Tutkimuksen maantieteellinen konteksti on Euroopassa, jossa on viimeisten 60 vuoden ajan poistettu työvoiman liikkuvuuden esteitä tiettyjen maiden väliltä. Suuri osa eurooppalaisista voi nykyään opiskella, työskennellä, tai viettää eläkepäiviään missä tahansa 28 Euroopan unionin (EU) jäsenmaasta tai asettua asumaan Sveitsiin, Norjaan, Islantiin tai Liechtensteiniin. Euroopassa sijaitseekin globaalisti ainutlaatuinen vapaan liikkuvuuden alue, jonka merkitys näkyy myös Suomesta muihin Euroopan maihin suuntautuvan muuttoliikkeen kasvuna Suomen liityttyä Euroopan talousalueen jäseneksi vuonna 1994 ja EU:n jäseneksi vuonna 1995. Tämä sosiologian tieteenalaan kuuluva tutkimus käsittelee yhden Euroopan sisällä muuttavan ryhmän, EU15 maihin muuttaneiden korkeasti koulutettujen suomalaisten, työmarkkinakokemuksia. Tutkimus pohjaa kahteen Working in Europe (2008 ja 2010) verkkokyselyyn sekä 18 ulkomaille muuttaneen suomalaisen haastatteluihin. Tutkimus pyrkii vastaamaan kolmeen empiiriseen kysymykseen: "Miksi korkeasti koulutetut osaajat muuttavat ulkomaille?", "Kuinka korkeasti koulutetut osaajat löytävät töitä ulkomailta?", ja "Minkälaiset taidot ja kvalifikaatiot edesauttavat tai vaikeuttavat kohdemaan työmarkkinoille siirtymistä ja minkälaisissa työpaikoissa nämä suomalaiset työskentelevät?". Olemassa olevien taitojen, koulutuksen ja aikaisemman työkokemuksen tunnustaminen on tärkeää erityisesti korkeasti koulutetuille muuttajille, jotka hakevat töitä ulkomailta. Tässä tutkimuksessa näihin tietoihin ja taitoihin viitataan kulttuurisen pääoman käsitteellä ja tutkimuksen teoreettinen tutkimuskysymys käsittelee tuon pääoman siirtymistä eurooppalaisten rajojen yli. Tutkimuksessa käytetty lähdekirjallisuus käsittelee kolmea teemaa: korkeasti koulutettujen osaajien muuttoliikettä, Euroopan sisällä tapahtuvaa liikkuvuutta sekä kulttuurista pääomaa ja muuttoliiketutkimusta. Tutkimus tarkastelee korkeasti koulutettujen suomalaisten työmarkkinakokemuksia ulkomailla. Vaikka tutkimuksen fokus on siten yksittäisten muuttajien tasolla, myös monet historialliset prosessit, kuten globalisaatio ja Euroopan integraatiokehitys, sekä kulttuuriset ja taloudelliset ilmiöt, vaikuttavat ulkomaille muuttoa harkitsevan päätöksentekoon. Siten myös yksilöä itseään laajemmat rakenteelliset ilmiöt osaltaan vaikuttavat siihen, miksi Suomesta muutetaan ulkomaille, milloin muutto tapahtuu sekä minne se suuntautuu. Tutkimuksessa todetaan, että kansainvälisesti suuntautuneille, suhteellisen nuorille ja hyvin koulutetuille Euroopan kansalaisille muutto EU:n sisällä on yksi mahdollinen väylä työmarkkinoille. Ulkomaille muutto nähdään usein kokeiluna, jota motivoivat erilaiset elämäntapaan ja henkilökohtaiseen kasvuun liittyvät tekijät eivätkä pelkästään urakehitys tai mahdollisuus parempiin ansioihin. Tutkimuksessa käytetään status-siirtymän käsitettä kuvaamaan sitä aikaa, jolloin koulutettu osaaja työskentelee koulutustaan vastaamattomissa töissä, opiskelee, on työttömänä tai hakee ulkomailta töitä Suomesta käsin. Status-siirtymää, jonka jälkeen muuttaja työllistyy koulutustaan ja/tai kokemustaan vastaaviin tehtäviin, tarkastellaan sekä sen ajallisen keston että työpaikan saamiseksi vaadittavien ponnistelujen kautta. Valtaosalle tämän tutkimuksen osallistujista tuo status-siirtymä oli ollut lyhytkestoinen ja sopivan työpaikan löytäminen ulkomailta oli ollut suhteellisen helppoa. Tutkimuksen osallistujat olivatkin hyvin tyytyväisiä työmarkkinatilanteeseensa ulkomailla. Osa tutkimukseen osallistuneista oli siirtynyt ulkomaille työnantajansa lähettäminä, ja osa oli rekrytoitu Suomesta suoraan johonkin tehtävään. Itsenäisesti ulkomailta töitä hakeneiden kokemuksissa oli yhtäläisyyksiä, vaikka tutkimukseen osallistuneet suomalaiset edustavatkin kovin erilaisia ammatteja ja koulutustaustoja. Työnhakutilanteissa esimerkiksi seuraavilla tekijöillä on ollut merkitystä: 1) tutkimukseen osallistuvien hyvä kielitaito oli auttanut heidän kulttuurisen pääomansa arvon määrittelyssä, 2) osallistujien suomalaisuus ja skandinaavisuus oli nähty positiivisen stereotypian kautta, 3) osallistujat olivat hakeneet työtä kansainvälisistä yrityksistä tai järjestöistä, joissa muutkin työntekijät ovat ulkomaalaisia ja 4) osa osallistujista oli löytänyt kilpailuetua siitä, että he kuuluvat pieneen muuttajaryhmään, joka osaa harvinaisia kieliä (suomi ja ruotsi). Tutkimuksen tulosten perusteella voidaan todeta, että korkeasti koulutettujen osaajien kulttuurinen pääoma siirtyy eurooppalaisten rajojen yli suhteellisen helposti, ainakin jos muuttaja on kotoisin Suomen kaltaisesta Pohjoismaasta. Ulkomailta töitä hakevan täytyy kuitenkin olla joustava ja valmis mukautumaan kohdemaan olosuhteisiin. Tähän tutkimukseen osallistuneet suomalaiset käyttivät kolmea eri strategiaa pyrkiessään kohdemaan työmarkkinoille: sopeutumista, erottautumista ja uudelleen orientaatiota. Tutkimuksen mukaan korkeasti koulutetut suomalaiset osaajat eivät kohtaa ylitsepääsemättömiä esteitä hakiessaan työtä muista EU-maista, mutta osaamista ja koulutusta vastaavan työpaikan löytäminen vaatii sopeutumista, määrätietoisuutta ja joskus jopa hakeutumista kokonaan toiselle ammattialalle. ; The geographical context of the study lies in Europe, where over the past 60 years a progressive lessening of restrictions on labour mobility between certain countries has taken place. It is possible for the majority of Europeans to study, work, or retire in any of the 28 European Union (EU) member states, as well as in Switzerland, Iceland, Norway, and Liechtenstein. Europe is thus a unique area, where sovereign states have given parts of their legislative power to supranational institutions and have given up one of the fundamental rights that define a nation state – that of deciding who can cross its borders. Increased mobility to other EU member states after Finland joined the European Economic Area (EEA) in 1994 and the EU in 1995 testifies to the fact that also Finns are taking advantage of the free movement regime. This sociological study examines the labour market experiences of one intra- European migrant group: highly skilled Finns who have moved to other EU15 countries. Based on two consecutive Working in Europe online surveys (2008, 2010) and 18 migrant interviews, this study addresses three empirical questions: "Why do highly skilled Finns move abroad?", "How do highly skilled Finns find work in the EU15 countries?", and "What kinds of skills and qualifications ease or impede labour market access and what kinds of jobs do these Finns work in?" The recognition of skills, educational qualifications and work experience, i.e. one's cultural capital, is a key question for any migrant and especially so for highly educated professional migrants. The main theoretical question asked therefore is: "How does the cultural capital of the highly skilled migrants transfer across intra-European borders?" The study engages with three related literatures focusing on highly skilled migration, intra-European mobility, and cultural capital during migration. The study examines the personal experiences of highly skilled Finns and thus the main focus of the study is on the micro level of international mobility. Yet also various historical processes, such as globalisation and Europeanisation, cultural phenomena, and economic developments outside the control of individual migrants influence the reasons why particular individuals decided to move, where they moved to and when they moved. The study concludes that for internationallyminded, relatively young and well-educated European citizens mobility in the EU area is one possible path among many, and experimenting with living abroad may be motivated by a range of different reasons related to lifestyle and personal growth that are not directly linked with one's professional career or the possibility of earning a better salary. The concept of status passage, i.e. a transitional period that is spent doing lowskilled jobs, studying, in unemployment, or continuing to work in Finland while applying for highly skilled jobs abroad, is used to describe how the Finns of the study entered the labour market of their destination country. It is examined through two dimensions: as the effort required in finding a job and in terms of its duration in time. The duration of the status passage had been short for most participants of the study and finding a highly skilled job had been relatively easy. The respondents were therefore quite content with their labour market situation in the new country. While many of the highly skilled Finns of the study moved abroad to continue on their professional career as intra-company transferees or because they were headhunted to a particular company, the study also notes four interrelated reasons for the experienced labour market success of those, who had looked for work on their own. First, their good language competence helped negotiate the value of their cultural capital abroad; second, participants were often seen through a positive Finnish or Scandinavian stereotypic image; third, the ease of finding work had often been based on applying for jobs in international workplaces; and fourth, the participants had found advantages from belonging to a small national group with skills in rather rare languages, Finnish and Swedish. Based on the results of this study it can be concluded that the cultural capital of highly skilled intra-European migrants' transfers across national borders rather smoothly, at least when they originate from a Scandinavian country such as Finland. Yet transnationally mobile individuals, however highly skilled and educated they are, must be willing and able to adapt to the situation in the local labour market. The Finns of this study used three strategies to facilitate labour market entry: adaptation, distinction, and re-orientation. The results of this study demonstrate that highly skilled Finns do not face insurmountable barriers when they enter the labour market of another EU country, but they are also not welcomed with open arms as brains gained: finding a highly skilled job in the country of destination demands adaptation, perseverance, and sometimes even a total re-orientation of one's career.

Transport has been identified as one of the biggest sectors that contribute to climate change (23%) due to its energy demand and polluting emissions and therefore one of the sectors that needs to take action to mitigate its impact. A few countries in Latin America (Brazil, Chile, Mexico and Colombia) have started their transport NAMA development and are at different stages in the process. Peru has started this process more recently and this report aims at facilitating the NAMA development and a strategy for its implementation. A key issue in the Peruvian case is the need to set a wave of change in the way transport is usually perceived and addressed in Peru. Thus this report considers both the requirements and changes needed in order to implement a successful and appropriate transport NAMA. What is a NAMA? A NAMA (Nationally Appropriate Mitigation Actions) is a concept that originated under the Conference of the Parties (COP) in Bali 2007, as a mechanism to engage "Nationally appropriate mitigation actions by developing country Parties in the context of sustainable development, supported and enabled by technology, financing and capacity-building, in a measurable, reportable and verifiable manner;". With two years of application; NAMAs have managed to attract transport sector decision-makers due to their alignment with national priorities and potential large financial and technical support to implement them. Overall Vision of a Transport NAMA in Peru The overarching aim for the transport NAMA in Peru is the achievement of the minimum optimum mobility required to stimulate economic growth and thus improve the quality of life. This report suggests that three areas of priority should be tackled in order to achieve the overarching aim – Urban Mobility, Energy Efficiency and the role of land use and planning – in the development and implementation of carbon emissions targets. In order to reduce emissions by any significant amount, it is necessary to devise measures for each of these priorities. For Urban Mobility, the measure to be adopted is the development of an integrated mobility system; for Energy Efficiency, the measure is the development of a programme to increase the energy efficiency of vehicles; for Land use and planning, the measure is to develop demonstrator Green Zones to show how low carbon living might work in reality. Each measure amounts to a set of interventions and each intervention has a set of Actions. The Actions are measurable, reportable and verifiable. In the draft NAMA, there are 16 Interventions and 51 Actions explained in Chapter 4 and some suggestions for indicators of successful outcomes (See chapter 4 intervention time frame tables). The dominance of the capital city of Lima and Callao in relation to the rest of the country means that significant effort needs to be made in the capital in order to influence the success of the policy at the national level. Many of the actions will therefore apply to and be developed in Lima and Callao. Most can be repeated elsewhere in the country as appropriate. A major finding is that to achieve the aim, it is crucially important to ensure coherent, consistent and comprehensive governance over the transport system, without which environmental and operational actions will fail. Therefore a major Mobility Reform must be put in place – some initial steps have already been taken but the path is longer than the political cycle; therefore in the case of Lima and Callao this reform could be facilitated by the creation of a Unified Technical Authority (UTA). This will incorporate all government bodies involved in transport in the capital city; to oversee the overall transport system in the city in order to have a low carbon means to provide the urban mobility required by the community. The UTA can then develop actions to optimise mobility for the population and improve the energy performance of the transport system by implementing the interventions. Some of the Actions suggested in the draft transport NAMA are substantive – designed to achieve the NAMA objectives. Other Actions are facilitative – intended to set up the governance and contextual situations required for successful implementation of the substantive actions. The report presents the arguments to support the choice of these outcomes, objectives, measures, interventions and actions and a suggested initial timescale for implementation. The 16 Interventions are (Please see Table 28 in appendix IV for summary of all actions): 1. Creation of a Unified Technical Authority 2. Mobility Reform for Lima and Callao 3. Creation of a Multi-institutional Transport NAMA Committee 4. Revision of draft Transport NAMA 5. Development of Travel Plans for commercial activity and employees 6. Development of an energy-efficient Mobility Plan 7. Support for education and training 8. Development, design and implementation of new infrastructure to encourage low energy mobility 9. Seek international finance for the implementation of the transport NAMA 10. Implement a vehicle labelling system and a compulsory system to achieve energy efficiency in light duty vehicles 11. Ensure that fuel quality is improved 12. Adopt mechanisms to achieve the declared emissions target 13. Design and Planning 14. Governance and Delivery 15. Carbon accounting and sustainability 16. Tendering and Feasibility Key Concepts Institutional Structure The overarching aim for the future of the world s citizens is the improvement in the quality of life – and Peru is no exception in this respect. This aim is so overarching that it extends beyond the limitations of political ideas and preferences: it is hard to imagine a political party not wishing to improve the quality of life of the population. It therefore extends beyond the political cycles of elections and terms of office, but requires commitment from all parties so that the initial actions are started immediately and there is a continuity of purpose – even if the methods and priorities change as one political philosophy is exchanged for another. The nature and scale of the problem (long term) transcends political differences, therefore it is necessary to have the right institutional structures in place in order to ensure that the technico-political discussions can take place in a meaningful way. A decision to implement a transport NAMA will require actions which will only return results beyond the current political cycle and this requires bold political action Technical Leadership Politicians have a duty to bring the societal consensus to the heart of government decision-making but sometimes this will conflict with the practical, technological and methodological requirements of the implementation of their decisions. However important and beneficial the political desire might be, the occasion does arise when it is simply not possible to put it into practice. Therefore there is a need to ensure that there is a body of technical wisdom at the disposal of the politicians. This wisdom includes the knowledge of what is possible, what happened before and an understanding of how to improve the predictions of what could happen in the future. This wisdom needs to be independent of political influence because its role is to provide advice that is independent of political wishes and, in effect, to provide the knowledgeable intelligence that enables politicians to be able to act in a responsible way with society s resources. It should be the norm that a politician turns to the technical leadership for objective advice of the highest order so that all decisions are made on the basis of the best evidence, advice and support. This requires technical leadership that is independent of the political process and therefore free from the changes that often occur as a result of the political cycle. Therefore continuity and leadership is also required at the technical level. Analytical Tools Three main tools have been selected to support the draft NAMA process; (1) the Outcome-based Strategy (OBS) which is a tool that formalises and facilitates the decision-making process; (2) the RED (Reduce, Exchange and Decarbonise) strategy which aims to drive and guide priorities increasing carbon reduction and improving quality of life; and (3) Multi-Criteria Analysis (MCA) which is an alternative method to cost-benefit analysis (CBA) enabling more effective assessments of strategic actions. Final remarks Further work is required in order to transform this draft transport NAMA into a NAMA proposal and this entails firstly the adoption and, if necessary, adjustment of the suggested interventions, followed by assessment of financial and incremental costs, development of appropriate metrics of success (including measurement, calculation, reporting and verification) and achievement of suitable GHG projections. Peru is currently recognised as a very promising emerging economy attracting international investment and the transport system plays a vital role in this economic development (transporting goods and people). Initial steps have already been taken to improve Mobility in the Metropolitan city (Lima and Callao), however more work needs to be done to ensure Peru s growth reaches its maximum potential. The large technical and financial support available and the potential social cobenefits that can be achieved, make a Transport NAMA the ideal tool to facilitate this goal.

Living Beyond Boundaries: West African Servicemen in French Colonial Conflicts, 1908-1962, is a history of French West African colonial soldiers who served in French Empire. Known by the misnomer tirailleurs sénégalais , these servicemen contributed to the expansion, maintenance, and defense of France's presence on several continents. The complex identity and shifting purpose of this institution were directly linked to French colonialism, but determined by numerous actors and settings. The men in the ranks of the tirailleurs sénégalais came from France's colonial federations in sub-Saharan Africa--French West Africa and French Equatorial Africa. During the twentieth century, tirailleurs sénégalais ' deployed to North Africa, the Levant, Indochina, and Madagascar, where their exploits brought them into contact with other imperial populations. Tirailleurs sénégalais played crucial roles in assembling and disassembling French empire. The tirailleurs sénégalais provide a unique West African perspective of France's colonial empire that challenges national and French colonial readings of this colonial military institution. Tirailleurs sénégalais were colonial soldiers and intermediaries who experienced French colonialism unlike other colonized peoples. As employees of the colonial state, West African soldiers were often among the first populations to experience novel colonial policy. As soldiers, they implemented those policies in foreign colonial populations. However, these men were not simply the conveyors of colonialism. Their imperial assignments in colonial wars evidenced the importance of lateral exchanges of knowledge and experience between colonial populations linked together by France's presence. The tirailleurs sénégalais demonstrate that the core-periphery model of historicizing colonialism, where information and historical causality flow unidirectionally from the French metropole into its colonies, is limited in portraying how people experienced colonialism. The roles of women and wives in the tirailleurs sénégalais ' history attest to the significance of cross-colonial exchange in the French colonial world. West African women followed their soldier/husbands to North Africa and Madagascar. Repatriating soldiers brought foreign wives home to French West Africa from Syria, Lebanon, and Indochina. Regardless of their origin or the setting of their interactions with soldiers, women affected the decisions that West African men made regarding their military service. By accounting for the importance of wives and marriage, this project also illustrates how women and soldiers challenged a secular colonial state to redefine marriage. Soldiers and wives convinced the colonial state to allot family allowances to polygynous Muslim West African soldiers. By emphasizing the importance of foreign women and cross-colonial exchange in the history of the tirailleurs sénégalais , this project problematizes histories of federal colonial institutions that are circumscribed by the boundaries of modern nation-states. Due to its composition and the range of its deployments, the tirailleurs sénégalais was an international enterprise. When shoehorned into the national history of a contemporary West African country, the tirailleurs sénégalais become a tool for interrogating French colonialism in that West African. These histories overemphasize the hand of France in the histories of West Africans and neglect the global influences on men who made French empire. When viewed through the lens of empire, the tirailleurs sénégalais also challenge the periodization of the colonial period. West Africans fought in the French-Algerian conflict after their home colonies were sovereign nations. The veterans of the tirailleurs sénégalais continue to rely on this historical relationship through the collection of their pensions. This project is informed by archival, published, and oral sources. They sources provide a nuanced understanding of the various worlds that tirailleurs sénégalais traipsed through in the twentieth century. The first half of this dissertation relies on French archival materials and published memoirs. These written sources were penned predominantly by French men, but the voices and agency of West African troops emerge in critical moments. These sources also portray French biases towards the tirailleurs sénégalais , as well as the ways in West African intermediaries contributed to French knowledge regarding their recruits. Roughly one hundred interviews conducted with veterans and their families inform the second half of this dissertation. Memory and oral history added complexity to the history presented by archival military documents. A source fraught with its own biases and omissions, veterans' memory of the past enriched this dissertation with anecdotal evidence. Their memories also illustrated how the fifty years since independence have influenced how they give importance particular events in their personal histories as soldiers and veterans. Living Beyond Boundaries chronologically, and geographically follows tirailleurs sénégalais ' imperial engagements in Morocco, Syria-Lebanon, Indochina, Madagascar, and Algeria. The West Africans in this dissertation were soldiers in the employment of France and large-scale conflicts act as the chronological framing device of this dissertation. Each chapter takes place in different imperial locations, but each analyzes recurring themes that illustrate how West Africans experienced the French colonial military and how they maintained empire. Chapter One introduces tirailleurs sénégalais and situates them within several genres of historical literature and accounts for the institution's nineteenth-century history. Chapter Two analyzes their deployment in the Moroccan "pacification" campaign, between 1908 and 1914. Tirailleurs sénégalais ' deployment in North Africa was an experiment that served as the springboard for subsequent deployments in French empire. The Moroccan campaign tested the adaptability of West African servicemen to military life in temperate climates, as well as challenged the French assumptions about their sub-Saharan African troops. The outbreak of the Great War brought the tirailleurs sénégalais to France. Chapter Three deals with pivotal legislation that reshaped the tirailleurs sénégalais . The Blaise Diagne Laws of 1915 and 1916 passed as result of the crises of the Great War. These laws secured citizenship for a minority of West Africans, who became obligated to service in the French military. The renegotiation of citizenship for military service led to the bifurcation of West African soldiers in the French Armed Forces--West African citizens served in the French metropolitan army and West African subjects in the tirailleurs sénégalais . Their experiences as soldiers diverged after the ratification of this legislation.After the armistice in 1918, tirailleurs sénégalais were diverted from France to serve in recently acquired French mandate territories--Syria and Lebanon. Chapter Four takes place in the interwar period, when the tirailleurs sénégalais ' role in empire was redefined as they fought in small-scale conflicts in the Levant and Morocco. The financial crisis of the 1920s and 1930s negatively impacted the colonial military's effort to improve and professionalize the tirailleurs sénégalais . The "hollow years" witnessed important processes in the tirailleurs sénégalais . The French military's attempt to professionalize the tirailleurs sénégalais was also thwarted by their paradoxical move to reestablish racial hierarchy in empire. The outbreak of World War II brought schizophrenia, paranoia and fratricide to the tirailleurs sénégalais . Chapter Five studies the division of empire into factions aligned with Free France and Vichy France. The tirailleurs sénégalais existed on both sides of this divide and found themselves facing one another on the battlefields of Syria when Allied forces attacked Vichy forces there. French Indochina fell under the authority of neighboring Japan and West African soldiers relied on romantic relationships with Indochinese women to survive the war. The reversals of World War II encouraged postwar challenges to France's authority in several of its colonies. Tirailleurs sénégalais ' participated in these events as colonizers and colonized peoples.The conclusion of hostilities in France were eclipsed by the Vietnamese Declaration of Independence. Chapter Six addresses the nine-year guerilla war in Indochina, where tirailleurs sénégalais found themselves overwhelmed by the intimacy and violence of close fighting quarters. This chapter is informed by veterans and their widows' memories, which illuminated the personal and psychological characteristics of this conflict. This was the first large-scale anti-colonial war where evidence suggests that tirailleurs sénégalais questioned their role in French colonialism. Deserters abandoned the French army for political reasons and for love. The romantic relationships between soldiers and Indochinese women led to the international migrations of inter-racial families to West Africa. West African communities dealt with the aftermath of the French-Indochinese Ware as their sons' families integrated into their households. After the conclusion of the Indochinese conflict in 1954, some tirailleurs sénégalais were redeployed immediately to the battlefields of Algeria. Chapter Seven uses the French-Algerian war as a backdrop for troops' demobilization and West Africa's decolonization. The French Constitutional Referendum in 1958 launched West African independence. West African soldiers became caught up in the extrication of France from West Africa, since both entities desired trained troops. As a result, tirailleurs sénégalais remained in France's employment after their natal countries were sovereign nations. West African soldiers' dual allegiance to France and their country of origin challenged the meaning and finality of political independence. The Conclusion takes this argument further by analyzing the contemporary relationships between tirailleurs sénégalais veterans, West African states and France.

This thesis concerns with the development and the validation of analytical methods for the determination of the mycotoxins aflatoxin B1, zearalenone and patulin, which occur frequently in food and feed. The toxic syndromes produced by them when ingested are known as mycotoxicoses. One of the first reports in history of mycotoxicoses is ergotism, caused by the fungus Claviceps purpurea. Nowadays ergotism is of minor importance; however the problem of mycotoxicoses and long term sub-acute exposure has not faded. Therefore, regulations have been established in many countries, and reliable testing methodology is needed to implement and enforce the regulatory limits. So far, several hundred different mycotoxins have been discovered, exhibiting different structural diversity, with various chemical and physicochemical properties, but only a few present significant food safety challenges. Among these are aflatoxins and ochratoxin A (produced by Aspergillus sp.), fumonisins, trichothecenes such as T-2, HT-2 toxins, deoxynivalenol and zearalenone (produced by Fusarium sp.), patulin (produced by Penicillium sp.) and ergot alkaloids (produced by Claviceps sp.) the most frequent occurring mycotoxins with the highest potential to adverse effects in humans and animals. The work of this thesis can be clustered into three parts as follows: (I) Method comparison and collaborative trial for the determination of aflatoxin B1 in medicinal herbs. This study was initiated upon the request of the European Pharmacopoeia since the regulatory limits for aflatoxin B1 in medicinal herbs were discussed in that moment. The methodology used has been adopted from existing methods for the determination of aflatoxin B1 in food. The food is extracted with an organic solvent followed by immunoaffinity clean-up and reversed-phase high performance liquid chromatography with fluorescence detection. The aim was to select the most suitable method parameters in order to obtain a method that allows the precise determination of aflatoxin B1 in a variety of medicinal herbs. Therefore acetone-water and methanol-water were tested as extraction solvents. Further, the influence of different post-column derivatisation options with electrochemically generated bromine, photochemical reaction and chemical bromination was compared. In addition, two different calculation modes peak height versus peak area were investigated concerning the precision on the evaluation of the rather small peaks that are obtained for aflatoxin B1 at low contamination levels. The different method parameters were applied in the collaborative study to three matrices: senna pods, ginger root and devil's claw root. As a result, the method with all tested variations was found to be fit-for-purpose for the determination of aflatoxin B1 in medicinal herbs at levels of 1 µg/kg and above. It could be concluded that the tested derivatisation methods had no influence on the analytical result in a range of 1 - 3 µg/kg for aflatoxin B1 in medicinal herbs. This is an interesting conclusion as control laboratories often have a preference for one or the other derivatisation method depending on their experience with one or the other system and its availability. 'A second method was adopted by single-laboratory validation for the determination of aflatoxin B1 in tiger nuts. The interest on tiger nuts rose on the fact of recent entries in the Rapid Alert System for Food and Feed regarding contamination with aflatoxin B1 in tiger nuts. This system allows the European Commission, EU member states and other associated countries to share information and take immediate action when potentially dangerous food or feed is detected on the market or at the border. Additionally a small survey of aflatoxin B1 content in chufa, which is a tiger nuts based soft drink in Spain, was conducted with the adopted method. The detection limit and the quantification limit were 0.02 µg/kg and 0.06 µg/kg respectively. The mean recovery at a level of 2 µg/kg was 88 % (n = 6) and the coefficient of variation 9 %. (II) Development and validation of an analytical method for the determination of zearalenone in infant food as well as in animal feed. The main challenge was to allow the determination of zearalenone at rather low concentrations in infant food, while being also able to deal with complex and more challenging matrices such as compound animal feed, due to their abundant interferences compounds. Previous work performed the determination of zearalenone in cereal grains and at higher levels. The method was validated in an international interlaboratory trial in which laboratories from EU member states, China, Turkey and Uruguay participated. Method performance parameters for both baby food and animal feed were calculated based on results for spiked samples blind duplicates at two levels and based on results for naturally contaminated samples blind duplicates at three levels. Test portions of the samples were spiked at levels of 20 µg/kg and 30 µg/kg zearalenone in baby food and at levels of 100 µg/kg and 150 µg/kg zearalenone in animal feed. As a result the method showed acceptable within-laboratory and between-laboratory precision for each matrix, as required by European legislation. Therefore, the newly developed method allows the enforcement of EU legislative limits for zearalenone in foods for infants at 20 µg/kg. (III) Development and validation of an analytical method for the determination of patulin in juices and purees for infants. The main challenge was to stress the method to determine patulin reliably at levels of 10 µg/kg in products intended for infants and young children. Previously developed methods for patulin were either collaboratively tested at higher levels, indicating that the lower limit for reliable quantification of patulin in such products was around 25 µg/kg or higher, or no validation data except single-laboratory validation were available. Method development focussed on improved and simplified extraction and clean-up procedures. A single liquid-liquid extraction in the presence of sodium sulfate as water binding agent showed sufficient extraction recovery rates for patulin in combination with a solid-phase extraction method, which trapped interfering substances and allowed the purification of patulin extracts without any pre-conditioning of the SPE cartridge. As a result, purees can be extracted without previous enzymatic treatment, as it is required by other methods that use multiple liquid-liquid extractions. Patulin was well separated from the main interfering compound 5-hydroxymethylfurfural during chromatography when using RP-HPLC columns that allow the separation of rather polar substances with mobile phases of more 99% of water. Additionally to this method A and due to the large number of laboratories that intended to participate in the validation process, the participants were split into two groups and a second method B was validated. This method B is a slightly modified version with the same principle as the one previously published by MacDonald et al. in 2000. The main modifications related to the aliquotation. Patulin is extracted three times from the juice or the de-pectinated puree with neat ethyl acetate. The combined ethyl acetate phases were re-extracted with sodium carbonate solution and evaporated. The residue was then re-dissolved in 0.1 % acetic acid solution and separated by HPLC as in method A. Both methods were tested for the determination of patulin in apple juice and fruit puree at the proposed European regulatory limit of 10 µg/kg. The methods were validated in an international interlaboratory trial in which laboratories from EU Member States, Japan and Brazil participated. Method performance parameters for both apple juice and fruit puree were calculated based on results for spiked samples blind duplicates at two levels and based on results for naturally contaminated samples blind duplicates at three levels for both methods. Test portions of the samples were spiked at levels of 10 µg/kg and 25 µg/kg patulin for both apple juice and fruit puree. In conclusion, the new developed method A showed acceptable within-laboratory and between-laboratory precision for both juice and puree at all levels, while method B only fulfilled partially the performance parameters as required by current EU legislation. Therefore, the newly developed method allows the enforcement of EU legislative limits for patulin in foods for infants at 10 µg/kg. Finally the development and in-house validation of a method for determination of patulin using ultra high pressure liquid chromatography in combination with a mass selective detector, resulting in a better chromatographic and analyte selective separation within a shorter time is described. This is of interest especially for projects in which larger amounts of results need to be generated. A survey with more than 200 samples of baby foods, apple purees and tomato purees from the EU food market was performed with this method. It indicated that during the period of 2006 almost all products were free of patulin and all products were compliant with current EU legislation.

Tutkimuksen ensimmäinen osa koostuu kolmesta esseestä, joissa käsitellään haitallisten hyödykkeiden verotusta. Haitallisilla hyödykkeillä tarkoitetaan tutkimuksessa hyödykkeitä, joiden kulutuksella on negatiivisia vaikutuksia kuluttajan hyvinvointiin tulevaisuudessa - esimerkkejä ovat epäterveellinen ruoka, alkoholi ja tupakka. Jos kuluttajat eivät ota riittävästi huomioon tulevaisuudessa koituvia haittoja, he kuluttavat oman hyvinvointinsa kannalta liikaa tällaisia hyödykkeitä. Verotuksella voi tällöin olla kulutusvalintoja korjaava vaikutus. Tutkimuksessa tarkastellaan haitallisten hyödykkeiden verotusta teoreettisten mallien avulla kolmesta näkökulmasta. Ensin tarkastellaan, millaiset hyvinvointivaikutukset verotuksella on eri väestöryhmissä, kun otetaan huomioon sekä verotuksen tulonjako- että terveysvaikutukset. Tutkimuksen tulosten perusteella voidaan arvioida esimerkiksi ajankohtaista keskustelua elintarvikeveron alentamisesta. Toisen esseen näkökulma on poliittinen: Esseessä pohditaan, onko esimerkiksi riittävän korkeille alkoholi- ja tupakkaveroille mahdollista saada poliittista kannatusta. Kolmas essee tuo tarkasteluun kansainvälisen ulottuvuuden: Esseessä käsitellään sitä, miten kansainvälinen verokilpailu heikentää mahdollisuuksia alentaa esimerkiksi alkoholin kulutusta korkean verotuksen avulla. Tutkimuksen tulosten perusteella minimivero on kansainvälistä veroharmonisointia parempi keino vähentää verokilpailun haittoja. Ensimmäisessä esseessä tarkastellaan haitallisten hyödykkeiden verotuksen hyvinvointivaikutusten jakautumista. Tutkimuksen kohteena olevat hyödykkeet ovat tyypillisesti sellaisia, joihin pienituloiset henkilöt käyttävät suuremman osan tuloistaan kuin suurituloiset. Näiden hyödykkeiden korkean verotuksen onkin katsottu vahingoittavan erityisesti pienituloisia; elintarvikeverotus on tästä hyvä esimerkki. Kun huomioidaan myös verotuksen terveysvaikutukset, arvio verotuksen vaikutuksesta eri tuloryhmien hyvinvointiin saattaa kuitenkin muuttua. On todennäköistä, että pienituloisten kysyntä reagoi veromuutoksiin enemmän kuin suurituloisten. Mikäli näin on, haitallisten hyödykkeiden korkean verotuksen myönteiset terveysvaikutukset olisivat suurimpia juuri pienituloisille. Esimerkiksi elintarvikkeiden verokohtelua mietittäessä saattaakin olla järkevää porrastaa verotusta elintarvikkeiden terveysvaikutusten perusteella. Toisessa esseessä tarkastellaan tilannetta, jossa haitallisten hyödykkeiden kulutus aiheuttaa ongelmia vain osalle kuluttajista, kun taas osa kuluttajista ottaa täysimääräisesti huomioon kulutuksen haitat. Haitallisten hyödykkeiden korkeasta verotuksesta on hyötyä nimenomaan ongelmakäyttäjille, mikäli verotus auttaa heitä vähentämään kulutustaan; muiden kulutusvalintoja korkea verotus rajoittaa turhaan. Esseessä osoitetaan, että riittävän korkeiden verojen on vaikea saada poliittista kannatusta, koska muut äänestäjät eivät ota huomioon ongelmakuluttajille koituvia hyötyjä. Myös verotulojen keräämiseen liittyvät motiivit voivat johtaa liian alhaiseen verotukseen: Jotkin hyödykkeet ovat niin haitallisia, että olisi järkevää asettaa verojen taso niin korkeaksi, että kulutus olisi hyvin vähäistä. Tällöin kuitenkin myös verotulot olisivat hyvin pienet. Kolmannessa esseessä tarkastellaan verokilpailun vaikutusta haitallisten hyödykkeiden, kuten alkoholin verotukseen. Esimerkiksi Euroopan Unionissa kuluttajat voivat vapaasti ostaa kotimaassa korkeasti verotettua tuotetta ulkomailta. Tutkimuksen johtopäätösten mukaan verotuksen terveysvaikutuksia ei kuitenkaan tällöinkään pitäisi sivuuttaa: Kotimaan korkean verotuksen vaikutus ulkomailta tuodun alkoholin määrään on pienempi kuin vähennys kotimaasta ostetun alkoholin määrässä. Verotuksella voidaan siis vähentää kulutuksen haittoja verokilpailusta huolimatta. Verokilpailun aiheuttamia ongelmia voidaan korjata koordinoimalla verojen tasoa esimerkiksi Euroopan Unionin jäsenmaiden kesken. Tutkimuksen tulosten perusteella on kuitenkin parempi asettaa haitallisille hyödykkeille riittävän korkea minimivero, kuin pyrkiä pelkästään verojen harmonisointiin. Veroharmonisointi poistaisi kuluttajien kannustimet ostaa haitallisia hyödykkeitä ulkomailta, mutta ei välttämättä poistaisi liian alhaisen verotuksen ja korkeiden terveyshaittojen tuomia ongelmia. Tutkimuksen toinen osa koostuu yhdestä itsenäisestä esseestä, jossa tarkastellaan teoreettisen mallin avulla sääntelyn vaikutuksia investointikannustimiin ja kilpailuun telekommunikaatiomarkkinoilla. Markkinoita sääntelevä viranomainen voi velvoittaa televerkkoyrityksen vuokraamaan verkkokapasiteettia muille operaattoreille, jotta telepalveluiden markkinoille syntyisi kilpailua vaikka televerkko pysyisikin monopolina. Tutkimuksen tulosten perusteella sääntely kuitenkin heikentää verkkoyrityksen kannustimia tehdä verkon laatua ja palvelujen kysyntää parantavia investointeja. Mikäli investoinnit hyödyttäisivät kilpailijoita enemmän kuin verkkoyritystä itseään, sääntely voi jopa johtaa kilpailijoiden aseman huononemiseen, vaikka sen alkuperäinen tarkoitus on edistää kilpailua. ; This thesis consists of two parts the first part comprises three essays that analyse different aspects of taxation of harmful goods in a situation where consumers have self-control problems. The second part, which consists of a single essay, examines the effect of access price regulation on investment and entry in telecommunications markets. The first part therefore explores a rationale for government intervention which has traditionally been controversial among economists, but has recently received more attention and also increasing acceptance within the profession: When we recognise that individuals can make errors in decision-making and may therefore fail to maximise their own welfare, there may be scope for government intervention that increases welfare. The intervention analysed in this thesis are taxes on harmful goods, or so called sin taxes. On the other hand, the second part of the thesis analyses a more traditional rationale for government involvement in the economy, namely distortions caused by market power. In the first part of the thesis, we extend the literature on the taxation of harmful goods in the presence of self-control problems in three main ways. In the first essay, we leave the question of optimal sin taxes aside, and analyse the factors that affect their incidence. We derive an incidence measure for taxes on harmful goods, as well as a condition for the case where sin taxes improve individual welfare. Secondly, we examine how taxes on harmful goods are determined in political equilibrium, and compare the equilibrium tax with the socially optimal level. The previous literature has focused on optimal sin taxes, and therefore our analysis of equilibrium taxes is an important extension to the literature. We also extend the previous literature by providing an explicit formula for the optimal sin tax in a second-best situation where consumers differ in their degree of self-control problems but a uniform tax is applied, and by comparing the optimal sin tax with the marginal distortion in consumption. Thirdly, we extend the analysis of sin taxes to an international context. More specifically, we examine a country whose government attempts to use taxation to reduce the consumption of a harmful good, and analyse the extent to which cross-border shopping and tax competition undermine the feasibility of this type of taxation. We also analyse whether policy coordination in the form of minimum tax rates or tax harmonisation can improve welfare. The practical implications of our findings can be summarised as follows. Firstly, considering tax incidence, we show that taxes on goods such as unhealthy food may be progressive. This is contrary to the common counter-argument against heavy VAT rates on necessities, which are usually regarded as regressive. The intuition for this result is that the self-control benefits of taxation depend importantly on the demand elasticity, and demand is typically more elastic for low income individuals. Therefore, when one considers for example lowering the VAT rate on food for redistributive reasons, it is important to note that in such exercises it is likely not to be optimal to treat all types of food equally. Secondly, we show that when consumers differ in their degree of self-control problems, equilibrium tax rates on harmful goods are likely to be too low from a social point of view. The intuition is that taxation has a large benefit for consumers with a severe self-control problem, and only a small negative impact on consumers with no self-control problems (whose consumption of highly harmful substances is low even in the absence of taxation - taxes therefore only impose a small distortion for these individuals). Individuals do not take this asymmetry into account in their voting decisions, and equilibrium sin taxes therefore cannot achieve the socially optimal outcome. There may thus be a case for quantity restrictions on some highly harmful substances. Thirdly, turning to the implications of international tax competition, we show that such competition should not lead governments to disregard paternalistic objectives of taxation completely: Taxation can still be used to lower harmful consumption. The intuition is that even if higher taxes at home lead consumers to buy harmful goods such as alcohol abroad, the increase in cross-border shopping is smaller than the corresponding reduction in domestic consumption. Regarding policy coordination, we show that countries should aim at implementing minimum tax rates on harmful goods, rather than at harmonising tax rates at some intermediate level between the original tax rates. This is because the problems associated with tax competition (both from the point of view of reducing harm from consumption and raising revenue) are caused by tax rates being too low, not by tax rate differentials per se. In the second part of the thesis, we analyse the effect of access price regulation on investment incentives and competition in telecommunications markets. We consider a model with a vertically integrated monopolist network provider who faces rival operators in the retail market. We examine the network operator s incentives for infrastructure investment. We find that investments are below the social optimum even when there is no regulation, and access price regulation further reduces investment incentives. We show that the underinvestment problem may have negative effects on the viability of competition. Access price regulation does not necessarily reduce the likelihood of foreclosure, and in the presence of regulation, rivals are most likely to be foreclosed when they would bring highest benefits to consumers.

EXECUTIVE SUMMARY Germany is one of the few industrialized nations in which the tobacco industry remains a legitimate force in business, government, science and society at large. Though Germany has been an international leader in environmental protection, the German tobacco industry has been successful in preventing the translation of knowledge of the dangers of pollution from secondhand smoke into effective public health policy through a carefully planned collaboration with scientists and policymakers and a sophisticated public relations program which it initiated in the 1970's and has been quietly running ever since. The tobacco industry in Germany founded the Verband der Cigarettenindustrie, a trade association, in 1948. Located in Germany's capital cities in order to as best as possible influence political decisions, the Verband includes all the multinational and national tobacco companies doing businessin Germany (7 in 2006). In Germany, secondhand smoke emerged as a political issue in the early 1970s, but the federal government failed to enact a proposed statutory law on protection from tobacco smoke. To date, there has been no passage of effective legislation for the protection against tobacco in public places. Understanding that secondhand smoke was the crucial issue for the tobacco industry's viability, the Verband engaged the issue long before the German government and the main voluntary health agencies, leading to the industry's continuing success in preventing government action to protect citizens from the toxic chemicals in secondhand smoke. The Verband influenced science and policy by challenging the scientific evidence linking secondhand smoke to disease by conducting or financing research, recruiting independent scientists, influencing high-level working groups and commissions, and by coordinating, sponsoring and participating in scientific conferences. In 1975, the "Research Council Smoking & Health" was created as an advisory body to the scientific department of the Verband to convey the impression that the tobacco industry was committed to objective exploration and further development of its product. Research that was deemed to be too sensitive to be contracted to outside researchers was conducted in a laboratory in Munich, headed by Franz Adlkofer. In 1992, the Research Council was replaced when the Verband created the VERUM foundation with Adlkofer as Scientific and Executive Director. The Medical Action Group on Smoking or Health, a small nongovernmental organization active in the protection of nonsmokers since the 1970s founded by medical scientist Ferdinand Schmidt, made numerous attempts to influence governmental health policy in Germany. The tobacco industry successfully responded by framing the Medical Action Group and Schmidt as out of the mainstream. Probably the most important health authority allied with the tobacco industry from the 1980s onwards was Karl Überla, President of the German Federal Health Office until 1985 and simultaneously head of a private research institute, the GIS, in Munich. In 1982, the Verband contracted with Überla's GIS for a study on "passive smoking and lung cancer." In 1983, a working group on smoking-related cancer risks was set up by the Federal Ministry of Health as part of Germany's contribution to the EU "Europe Against Cancer" program. Of the 24 members the Ministry invited to comprise this working group, at least five individuals, Franz Adlkofer, Dietrich Schmähl, Gerhard Lehnert, Klaus Thurau and Jürgen v. Troschke, had worked for or received funds from the Verband. Overall, the tobacco industry in Germany has been able to maintain a level of respectability that allowed it access to high-level authorities and scientists who either themselves held a policy-relevant office or served on political advisory bodies, including Karl Überla, President of the Federal Health Office, Dietrich Henschler, Chairman of the MAK-commission, and Helmut Valentin, President of the Bavarian Academy for Industrial and Social Medicine. Despite the fact that public attitudes in Germany were very supportive of government action to restrict smoking, the industry worked to cast tobacco control as a serious threat to the European culture that was portrayed as too open, modern and enlightened for such action. Secret tobacco industry polling showed even higher levels of support for smoking restrictions in Germany than in the United States; still, the German tobacco industry portrayed policies protecting workers from secondhand smoke as examples of US extremism. Several unsuccessful efforts to pass non-smoker protection legislation followed in subsequent years, and on October 3, 2002, a revised workplace ordinance took effect that nominally puts the duty on employers to protect their employees from secondhand smoke in the (non-hospitality) workplace; still, the ordinance overall failed to guarantee smokefree workplaces and as of January 2006, the German government had not established any meaningful program to promote implementation and enforcement of the ordinance. In 2003, approximately one-third (32.5%) of Germans were smokers. Recent data shows at least 9 persons die from passive smoking each day in Germany. As this calculation only takes into account frequent domestic exposure of nonsmokers, the actual death toll is likely to be much higher. Still, as of 2006, with few smokefree laws in place, none of the major voluntary health agencies in Germany had continuously made secondhand smoke a major topic. Public health policymaking in Germany remains dominated by tobacco interests. KURZFASSUNG Deutschland ist eines der wenigen industrialisierten Länder in denen die Tabakindustrie heute in derGeschäftswelt sowie vonseiten der Regierung, der Wissenschaft und der Gesellschaft im Allgemeinen noch als eine legitime Größe angesehen wird. Obgleich Deutschland im Umweltschutz international eine Führungsrolle einnimmt, hat es dieTabakindustrie in Deutschland erfolgreich verstanden, die Umsetzung der Erkenntnisse über die Schädlichkeit des Passivrauchens in wirksame Gesundheitspolitiken zu verhindern. Sie bediente sich hierzu einer sorgfältig geplanten Kollaboration mit Wissenschaftlern und politischen Entscheidungsträgern, und eines ausgeklügelten PR-Programms das in den 1970er Jahren eingeleitet wurde und seitdem still betrieben wird. Die Branchenorganisation, der Verband der Cigarettenindustrie (VdC, kurz "Verband") wurde im Jahr 1948 von der Tabakindustrie in Deutschland gegründet. Der Verband vertritt sowohl nationale als auch multinationale Tabakkonzerne, die in Deutschland ihre Geschäfte treiben und war bzw. ist in der bundesdeutschen Hauptstadt (Bonn, Berlin) ansässig, um politische Entscheidungen bestmöglich zu beeinflussen. Bereits in den frühen Siebzigerjahren wurde das Thema Passivrauchen in Deutschland zum Politikum, doch die Bundesregierung schaffte es nicht, einen damals existierenden Gesetzesvorschlag für eine Rechtsvorschrift zum Schutz vor Passivrauchen zu erlassen. Vielmehr hat die Bundesregierung es bis heute versäumt, eine wirksame Gesetzgebung zum Schutz vor Tabakrauch im öffentlichen Raum zu erlassen. Aufgrund der Einsicht dass Passivrauchen der entscheidende Faktor für Lebensfähigkeit der Tabakindustrie ist, hat sich der Verband bereits lange vor der Bundesregierung und den wichtigsten Organisationen im Gesundheitswesen und Interessengemeinschaften dieses Thema zu eigen gemacht. Dies hatte zur Folge, dass die Tabakindustrie Regierungshandeln zum Schutz der Bürger vor den giftigen Inhaltsstoffen des Tabakrauchs erfolgreich verhindert hat. Der Verband hat Einfluss auf Wissenschaft und Politik genommen indem er die wissenschaftlichen Erkenntnisse über den Zusammenhang von Passivrauchen und Krankheit bestritten hat, Forschungsarbeiten durchgeführt oder finanziert hat, unabhängige Wissenschaftler rekrutiert hat, Einfluss auf hochrangige Arbeitsgruppen und Kommissionen genommen hat sowie an wissenschaftlichen Tagungen teilgenommen, diese koordiniert oder finanziell gefördert hat. Im Jahr 1975 wurde der "Forschungsrat Rauchen und Gesundheit" gegründet. Er diente der Wissenschaftlichen Abteilung des Verbandes als Beratungsorgan und sollte den Eindruck vermitteln, dass die Tabakindustrie sich der objektiven Erforschung und Weiterentwicklung seines Produktes verschrieben hat. Untersuchungen die als zu heikel galten, um sie an externe Wissenschaftler zu vergeben wurden in einem Labor in München durchgeführt das von Franz Adlkofer geleitet wurde. Im Jahr 1992 wurde der Forschungsrat Rauchen und Gesundheit ersetzt durch die vom Verband gegründete Stiftung VERUM, deren Wissenschaftlicher und Geschäftsführender Direktor wiederum Adlkofer wurde. Der Ärztliche Arbeitskreis Rauchen und Gesundheit, eine kleine Nichtregierungsorganisation, die seit den 1970er Jahren im Bereich Nichtraucherschutz aktiv ist und von Ferdinand Schmidt gegründet wurde, machte zahllose Versuche, die Regierungspolitik Deutschlands zu beeinflussen. Die Tabakindustrie reagierte darauf- erfolgreich - damit, dass sie den Ärztlichen Arbeitskreis Rauchen und Gesundheit und Schmidt als jenseits der politischen Mitte darstellte. Vermutlich die wichtigste Autorität im Gesundheitsbereich, die mit der Tabakindustrie seit den 1980er Jahren verbündet war ist Karl Überla, bis 1985 Präsident des Bundesamtes für Gesundheit und zugleich Leiter einer privaten Forschungseinrichtung in München, der Gesellschaft für Information und Statistik in der Medizin (GIS). Im Jahr 1982 nahm der Verband Überla's GIS unter Vertrag für eine Untersuchung über "Passivrauchen und Lungenkrebs". Im Jahr 1983 stellte das Bundesgesundheitsministerium eine Arbeitsgruppe über "Krebsgefährdung durch Rauchen"zusammen, als ein Beitrag vonseiten Deutschlands zum EU-Aktionsprogramm "Europa gegen den Krebs". Von den 24 Mitgliedern, die das Ministerium geladen hatte, hatten zumindest fünf Personen, Franz Adlkofer, Dietrich Schmähl, Gerhard Lehnert, Klaus Thurau und Jürgen v. Troschke für den Verband gearbeitet oder von diesem Finanzmittel erhalten. Im Großen und Ganzen ist es der Tabakindustrie in Deutschland gelungen, einen Grad der Angesehenheit aufrechtzuerhalten, die ihr Zugang zu hochrangigen Autoritäten und Wissenschaftlern verschaffte, die entweder selbst politikrelevante Ämter innehatten oder die als Sachverständige oder Mitglieder von wissenschaftlichen Beiräten direkten Zugang zur Politik hatten. Beispiele hierfür sind Karl Überla, Präsident des Bundesgesundheitsamtes, Dietrich Henschler, Vorsitzender der MAK-Kommission, und Helmut Valentin, Präsidentder Deutschen Gesellschaft für Arbeitsmedizin sowie der Bayrischen Akademie für Arbeits- und Sozialmedizin. Trotz der Tatsache, dass die Einstellung der deutschen Bevölkerung Einschränkungen des Rauchens deutlich unterstützt, war die Tabakindustrie bemüht, die Tabakkontrolle als eine ernsthafte Bedrohung für die Europäische Kultur darzustellen, indem diese als zu offen, modern und aufgeklärt für derartige Aktivitätenporträtiert wurde. Ungeachtet der Tatsache, dass Umfragen die von der Tabakindustrie durchgeführt und geheim gehalten wurdenfür Deutschland sogar eine stärkere Befürwortung von Einschränkungen des Rauchens zeigten als in den Vereinigten Staaten, karikierte die Tabakindustrie in Deutschland Maßnahmen zum Schutz der arbeitenden Bevölkerung vor Passivrauch als US-amerikanischen Extremismus. Etliche erfolglose Anläufe zur Verabschiedung eines Nichtraucherschutzgesetzes folgten in den Jahren darauf und am 3. Oktober 2003 trat die novellierte Arbeitsstättenverordnung in Kraft, die die Arbeitgeber nominelldazu verpflichtet, ihre Angestellten am Arbeitsplatz vor dem Tabakrauch zu schützen (ausgenommen sind Arbeitsstätten mit Publikumsverkehr). Durch diese Verordnung werden jedoch übergreifend keine rauchfreien Arbeitsplätze geschaffen und bis Januar 2006 hatte die Bundesregierung noch kein bedeutsames Programm aufgelegt um die Umsetzung und Vollzug der Verordnung zu fördern. Im Jahr 2003 waren nahezu ein Drittel (32,5%) der deutschen Bevölkerung Raucher, neueste Daten zeigen, dass in Deutschland täglich mindestens neun Menschen an den Folgen des Passivrauchens sterben. Da dieser Berechnung lediglich die häufige Exposition von Nichtrauchern zu Hause zugrunde liegt, ist die wirkliche Zahl der Todesopfer wahrscheinlich deutlich höher. Dennoch garantieren bisher nur wenige Gesetze Rauchfreiheit und auch sonst hat bis heute keine der wichtigsten Gesundheitsorganisation in Deutschland sich kontinuierlich dem Passivrauchen angenommen bzw. dieses zu einem Hauptthema gemacht. Die Gesundheitspolitik wird in Deutschland bis zum heutigen Tag von Tabakindustrieinteressen dominiert.

This work examines the social construction of migrants living with HIV/AIDS in the Finnish welfare state through the concepts of postmodern illness, social memory and human rights. Taking a qualitative approach, the study explores how narratives of AIDS have been articulated in public policymaking and social practices concerning HIV/AIDS. Through a close reading of Finnish law and health information texts, the thesis examines how the interaction between cultural practices and social structures articulated meanings and absences on the issue of migrants and HIV in Finland. In-depth interviews of people living with HIV, as well as policymakers and practitioners, are also presented. The four primary research questions are: How has HIV/AIDS been constructed as an exceptional health issue internationally and how has it emerged out of globalized trends in socio-economic development, migration, and the traditions of public health and social work? What kinds of stories have been told about HIV/AIDS and how have they been organized as narratives to emplot AIDS in global and local social and health policies? How are migrant identities and rights constructed in Finland, specifically in the intersection of legal, social and health definitions for migrants living with HIV/AIDS? What sense of cultural identity and belonging is constructed at the core of access to Finnish social and health services for people living with HIV/AIDS and how is it manifested? The dissertation first examines how the meanings of globalization and accompanying socio-economic transformations have been articulated towards the end of the twentieth century. HIV/AIDS is considered as the first disease of globalization where patterns of the pandemic mirror global inequalities. The work examines the fragmenting pressures of the neoliberal push for privatization on public health and the welfare state. It then moves on to explore the growth of transnational migration as a consequence of increasing global income inequality and structural violence, which raises new challenges to citizenship, democracy and the basis of the welfare state. Through a discussion of how the AIDS pandemic was storied, the work suggests that the public policy that emerged in the early days of the AIDS pandemic reflected the complexity of diverse narrative plots. Many of the narrative invisibilities and erasures reveal the inequalities of globalized societies on local levels. HIV/AIDS became an exceptional health issue through the common efforts of community action groups and public health professionals. Despite these efforts to construct HIV/AIDS as an exceptional disease requiring special care as well as unique prevention and harm reduction interventions, it remains highly stigmatized disease in most societies and very expensive to treat. This presents great challenges to social work with people living with HIV/AIDS. Finally, the work focuses on the local level of the global story of AIDS. Through an analysis of Finnish texts, such as newspaper articles and academic theses, as well as personal interviews, it traces the chronology and development of the Finnish epidemic. International narratives of AIDS are tied to the shaping of articulations of AIDS policy in Finland. The work moves on to explore how immigration policy in Finland is mediated through social memory. It then locates migrants in Finnish social and health law, arguing that migrants occupy an ambivalent location in constructions of equality in the Finnish social and health care system. Interviews of Finnish people and migrants living with HIV/AIDS as well as professionals and policymakers in the field are juxtaposed to explore the complex terrain of migrants social and health needs as well as the realities of social care in Finland. Through a close reading of health information material produced by AIDS agencies, the work explores the invisibility of migrants in these activities and policies of these agencies and their material. It argues that migrants access to social care can be seen as limited by the lack of recognition of their needs. The paucity of migrant stakeholders and researchers in the development of HIV/AIDS care policy and national prevention strategy can also be seen as a barrier to empowering migrant communities. The interaction between cultural practices and social structures in the Finnish welfare state tends to articulate a culturally normative consensus on care needs. The lack of acknowledgment of cultural competence as an essential element of care and professional training can be seen as articulating indirect discriminatory practices. Finally, the silence and invisibility of migrants in Finnish HIV services is considered through a reflection of two in-depth interviews with migrants living with HIV/AIDS. ; This work examines the social construction of migrants living with HIV/AIDS in the Finnish welfare state through the concepts of postmodern illness, social memory and human rights.

[SPA] El turismo rural comunitario (TRC) es un tipo de turismo que se encuentra en auge en Latinoamérica, con una especial característica consistente en que son las propias comunidades rurales las que lideran dichos proyectos turísticos, que no suponen el centro de su desarrollo socioeconómico, sino un complemento a sus actividades rurales tradicionales. Es además un medio que dichos colectivos utilizan para ir mejorando su dotación de recursos naturales y culturales, implicando importantes beneficios sociales para la población local, como la reducción de la pobreza, la fijación de la población en su territorio, la valorización de las tradiciones culturales propias, y la promoción y empoderamiento social de colectivos más frágiles en el mundo rural, tales como las mujeres y los jóvenes. En este sentido, el TRC se convierte en un medio muy relevante para la sostenibilidad de las comunidades rurales que consolida y promociona su manera de vivir, ayuda a recuperar su medio ambiente, y abre sus comunidades a visitantes respetuosos con el entorno que buscan conocer cómo viven estas gentes en entornos rurales tradicionales. El objetivo de la tesis es básicamente aprender de los proyectos de TRC que están llevando a cabo las comunidades rurales del Oeste de Nicaragua desde hace ya más de 15 años, en especial en lo relativo a las cuestiones de sostenibilidad turística. Para ello se aplica un enfoque basado en la dimensión socio-cultural del proceso, lo que aporta una visión novedosa del mismo y sienta las bases para un desarrollo futuro de esta literatura muy nueva en el sector del turismo y la gestión de proyectos. Con este objetivo, se realiza un estudio empírico de campo sobre dichas comunidades rurales, contactando con sus líderes en un principio al objeto de identificar los aspectos más relevantes de estos proyectos de TRC. Posteriormente, con dicha información se diseñan unos cuestionarios amplios y se pasan a una muestra de la población rural de manera que aporten la información de base del conjunto de la investigación de la Tesis Doctoral. Con esta información, se han construido básicamente dos bloques de la investigación. Tras una primera introducción en el capítulo primero sobre el contexto de análisis del TRC y sus propias características en las comunidades del Oeste de Nicaragua, el capítulo segundo se centra en la identificación de la idea de comunidad como la variable clave que promociona y coordina todo el proceso de lanzamiento de los proyectos de TRC, confiriendo además la sostenibilidad al conjunto del proyecto, desde dimensiones sociales, culturales, respeto al entorno y consolidación de la vida rural comunitaria como objetivo final de todos los proyectos de TRC de esta zona. En un tercer capítulo, este enfoque se amplía incluyendo algunas otras piezas clave del proceso de desarrollo del TRC, como son el liderazgo y la contribución de los gobiernos nacional y local en la generación de un marco legal de gobernanza nacional para la sostenibilidad turística, así como mediante la provisión de las necesarias infraestructuras y apoyo técnico y en capacitación para las comunidades rurales y sus habitantes. En todo momento se identifica así mismo la necesidad de contar con capital humano, experiencia y recursos por parte de la comunidad rural como condición necesaria para el inicio de cualquier proyecto de TRC exitoso y sostenible. Como resultado de dicho apoyo público y de cooperación con las comunidades rurales en el inicio y durante el desarrollo de los proyectos de TRC, se observan en este capítulo tercero algunos efectos relevantes del propio TRC, como son la promoción y empoderamiento social de las mujeres rurales, y a través de esta vía, la generación de importantes beneficios económicos, culturales, sociales y en el patrimonio natural de la población local. Tras estos dos capítulos se incluyen las principales conclusiones y recomendaciones de la Tesis Doctoral, en línea con los propios resultados de la misma. La Tesis incluye en su metodología dos modelos teóricos y su contrastación empírica mediante técnicas de Modelos de Ecuaciones Estructurales (SEM en su aceptación inglesa), a través del uso del software Smart PLS 3.2, estando además redactada en idioma inglés y contando con una publicación del capítulo segundo en el International Journal of Contemporary Hospitality Management (Q1 en JCR-SSCI en Management), lo que le confiere un valor añadido a la investigación que aquí se presenta. [ENG] Community-based Rural Tourism (RCT) is a type of tourism significantly growing in Latin America, with a special characteristic that the rural communities themselves are leading these tourism projects, not being the core of their community income sources, but a complement to their traditional rural activities. These activities also help rural communities to improve their stocks of natural and cultural resources, involving important social benefits for the local population, such as poverty reduction, the fixation of the population in their territory, the appreciation of their own cultural traditions, and the promotion and social empowerment of weaker groups in the rural world, such as women and young people. In this sense, RCT becomes a very relevant mean for the sustainability of rural communities that consolidates and promotes their way of life, helping to recover their environment, and opening their communities to friendly visitors who seek to know how these people live at their traditional rural environments. The objective of this PhD Thesis is basically to learn from the RCT projects that are being carried out by the rural communities of Western Nicaragua for more than 15 years now on, in what regards to tourism sustainability issues. To this end, an approach based on the socio-cultural dimension of the process is applied, which provides a novel vision of the process and lays the foundation for the future development of this very new literature in the field of tourism and project management. With this objective, an empirical field study is carried out on these rural communities, contacting their leaders at first in order to identify the most relevant aspects of these RCT projects. Subsequently, searching for the information basis for the Thesis, extensive questionnaires are designed and a sample of the rural population is taken so that they can provide the work field information for the present Doctoral Thesis research. The research includes basically two research blocks: After an introduction in the first chapter on the context of the RCT projects and related characteristics for the West of Nicaragua, the second chapter focuses on the identification of "the community" construct as the key variable in the promotion and coordination of the whole process, and in the end the key piece conferring sustainability to the whole project from the social and cultural dimension, in environmental terms, and in regards to the consolidation of the rural community life, this being its final objective of the RCT projects developed. In a third chapter, the approach is extended to include some other pivotal pieces of the RCT process, including the relevant leadership of national and local governments in the generation of a governance legal framework for tourism sustainability, as well as through the provision of the needed infrastructure and technical and training support for rural communities and their inhabitants. Besides, the presence of human capital, experience and resources of rural communities and local population is identified as a necessary condition for the launching of any successful and sustainable RCT project. As a result, some relevant effects emerging from rural tourism experiences are presented along this third chapter, like the process of social empowerment of rural women, and through this, the generation of important economic, cultural, social and environmental benefits arising for and spreading through the entire local population. After these two chapters, the main conclusions and recommendations of the doctoral thesis are presented, synthetizing the main results of the investigation. The PhD Thesis also accounts for relevant methods of analysis, and develops two theoretical original models and their empirical estimates, through Structural Equation Modelling (SEM) techniques, and using the Smart PLS 3.2 software. The Thesis is written in good English language, reaching a paper from the second chapter in the International Journal of Contemporary Hospitality Management (Q1 in JCR-SSCI in Management), giving an added value to the research. ; Escuela Internacional de Doctorado de la Universidad Politécnica de Cartagena ; Universidad Politécnica de Cartagena ; Programa de Doctorado en Ciencias Económicas, Empresariales y Jurídicas

The Breslau arts scene during the Weimar period was one of the most vibrant in all of Germany, yet it has disappeared from memory and historiography. Breslau was a key center for innovative artistic production during the Weimar Republic; recovery of its history will shed new light on German cultural dynamics in the 1920s. Such a study has art historical significance because of the incredible extent of innovation that occurred in almost every intellectual field, advances that formed the basis for aesthetic modernism internationally and continue to affect the course of visual art and architecture today. Architecture education, just one example in many, is still largely based on a combination of the Bauhaus model from the 1920s and the model developed at the Breslau Academy of Fine and Applied Art. The exploratory attitude encouraged in Weimar era arts endeavors, as opposed to the conformism of academic art, is still a core value promoted in contemporary art and architecture circles. Given the long-lasting influence of Weimar culture on modernism one would expect to find a spate of studies examining every aspect of its cultural production, but this is not the case. Recent scholarship is almost exclusively focused on Berlin and the Dessau Bauhaus. Although both interests are understandable, the creative explosion was not confined to these cities but was part of a larger cultural ethos that extended into many of the smaller regional centers. The Expressionist associations the Blaue Reiter in Munich and Brücke in Dresden are two well-known examples. Equally, innovation was not confined to a few monumental projects like the Stuttgart Weissenhofsiedlung but part of a broader national cultural ethos. The dispersion of modernism occurred partly because of the political history of Germany as a loosely joined confederation of small city states and principalities that had strong individual cultural identities before unification in 1871 but also because of the German propensity to value and take intense pride in the Heimat, understood both as the hometown and the region. Heimatliebe translated into generous support for cultural institutions in outlying cities. Host to a roster of internationally acclaimed artists and architects, major collectors, arts organizations, museums, presses, galleries, and one of the premier German arts academies of the day, Breslau boasted a thriving modern arts scene until 1933 when the Nazis began their assault on so-called "degenerate" art. This book charts the cultural production of Breslau-based artists, architects, art collectors, urban designers, and arts educators, who were especially interesting because they operated in the space between the margins of Weimar-era cultural debates. Rather than accepting the radical position of the German avant-garde or the reactionary position of German conservatives, many Breslauers sought a middle ground. It is the first book in English to address this history and presents the history in a manner unique to any studies currently on the market. 'Beyond the Bauhaus' explores the polyvalent and contradictory nature of cultural production in Breslau in order to expand the cultural and geographic scope of Weimar history; the book asserts a reciprocal dimension to the relationship between regional culture and national culture, between centers like Breslau and the capital Berlin. With major international figures like the painters Otto Mueller and Oskar Moll, architects Hans Scharoun and Adolf Rading, urban planners Max Berg and Ernst May, collectors Ismar Littmann and Max Silberberg, and an art academy that by 1929 was considered the best in Germany, Breslau clearly had significance to narratives of Weimar cultural production. 'Beyond the Bauhaus' contributes the history of German culture during the Weimar Republic. It belongs alongside histories of art, architecture, urban design, exhibition, collecting, and culture; histories of the Bauhaus; histories of arts education more broadly; and German history.

V dizertaciji sem poskušal raziskati, kako oskrba z energijo v vsaki od štirih svetovnih velesil (EU, ZDA, Ruski federaciji, Ljudski republiki Kitajski) vpliva na njihovo zunanjo energetsko politiko, kateri od treh elementov energetske politike (konkurenčnost, varnost oskrbe, trajnostnost) odraža zunanjo energetsko politiko teh držav in kako lahko različne regionalne iniciative iyhajajoče iz zunanje energetske politike teh držav pojasnjujemo s teorijo neofunkcionalizma. Prvo poglavje želi predstaviti neofunkcionistično teorijo kot teorijo regionalne integracije. Najprej analizira poskus Jeana Monneta za spodbujanje evropske integracije, ki so jo po drugi svetovni vojni ilustrirale Evropske skupnosti: Evropska gospodarska skupnost, Euratom in Evropska skupnost za jeklo in premog. Neofunkcionalizem je teorija, ki razlaga proces integracije na regionalni ravni glede na naraščajoče vzajemne gospodarske odnose med državami. Analizira sposobnost regionalnih organizacij za reševanje sporov in oblikovanje mednarodnih pravnih režimov, znotraj katerih lahko nadnacionalna tržna pravila nadomestijo nacionalne regulatorne režime. Integracijo pojasnjuje tudi s specializacijo elit in s pozitivnim učinkom prelitja (spill over effect), ki se kaže v nujnosti sodelovanja med sektorji, povezanimi s tistim sektorjem, v katerem se je regionalno sodelovanje prvič začelo. Drugo poglavje na kratko predstavlja 130 let zgodovine regulacije za zaščito konkurence na energetskih trgih, približno 80 let izzivov glede varnosti oskrbe in prestopa te teme v politiko ter približno 70 let stremljenja k trajnostnosti v sodobni energetski politiki. Tretje poglavje predstavlja strukturo oskrbe z energijo v vsaki od analiziranih svetovnih velesil. Očitno je, da so energetski trgi (nafta, plin, elektrika) v ZDA in EU zelo konkurenčni in učinkoviti. Velesili si prizadevata za trajnostnost in nenehno zmanjšujeta izpuste škodljivih emisij iz elektrarn, v prometu ter pri drugih dejavnostih. Medtem, ko je EU močno odvisna od uvoza (leta 2017 je uvozila več kot 55% vseh virov energije), so se ZDA v zadnjih 15 letih iz največjega uvoznika energetskih virov na svetu razvile v neto izvoznico in leta 2018 dosegle energetsko samozadostnost. Ruski indeks neto uvoza energije znaša -84%. Po podatkih iz leta 2014 je država ena največjih neto izvoznikov nafte (približno 10% svetovne proizvodnje) in plina (blizu 20% svetovne proizvodnje). Leta 2018 je bila izvožena količina energije skoraj enaka tisti, ki jo je država v tem letu porabila. Kljub energetskemu izobilju, ima Rusija močno regulirane in neučinkovite trge s plinom, nafto in električno energijo. Med štirimi analiziranimi velesilami daleč najmanj učinkovito izrablja svoje energetske vire. Monopol državnega podjetja Gazprom postaja vedno bolj vprašljiv zaradi vse manjših koristi, ki jih tako stanje prinaša Rusiji. Posledično naraščajo pritiski na Moskvo za reformo energetskega (zlasti plinskega) sektorja. Do zdaj je ruska vlada bolj ali manj odklanjala strukturne reforme in se poskušala prilagajati novim okoliščinam s prerazporejanjem obstoječih dohodkov. Kitajska počasi liberalizira svoj trg s plinom. Reforma, ki je v devetdesetih pritegnila v proizvodnjo električne energije nove, zasebne vlagatelje, je bila vmes že odpravljena, zasebni vlagatelji pa izrinjeni. Plin, premog, nafto ter proizvodnjo električne energije v glavnem nadzirajo državna podjetja, ki praviloma ne dopuščajo konkurence. Kitajska je leta 2017 porabila 22% vseh svetovnih virov energije in je bila tako daleč največji porabnik energije na vsem svetu. Kitajska izkoplje in sežge približno polovico svetovnega premoga in je tako močno netrajnostno usmerjena. Količina izpustov škodljivih emisij iz elektrarn ostaja visoka in stabilna, emisije CO2 pa se nenehno povečujejo. Se pa Kitajska v zadnjih letih veliko bolj osredotoča na storitveno ekonomijo in proizvodnjo elektrike iz obnovljivih virov. Kitajski indeks neto uvoza energije je 15%, kar kaže na zmerno odvisnost od uvoza. Četrto poglavje je namenjeno analizi zunanje energetske politike EU v globalnem kontekstu zapletenih energetskih odnosov. Energetika je že zelo dolgo politično občutljiv sektor in je kot tak tesno povezan z državno suverenostjo in nacionalnimi interesi. Posledično so se bruseljska prizadevanja za oblikovanje skupne zunanje energetske politike, ob delitvi pristojnosti z državami članicami in ob upoštevanju skrbno pripravljenega kompromisa iz člena 194 Pogodbe o delovanju EU, izkazala za zelo zahteven in težko dosegljiv cilj. Dejstvo, da je Evropska unija močno odvisna od tujih dobaviteljev energije (med katerimi ima Rusija s svojo vizijo političnim ciljem podrejene energetske politike najpomembnejšo vlogo), dodatno omejuje težnje EU po uvedbi univerzalnih tržnih pravil v energetskem sektorju. Pri promociji tržnih pravil kot osnovi energetske politike je EU vseeno uspelo doseči nekaj napredka, zlasti z ustanovitvijo Evropskega gospodarskega prostora in Energetske skupnosti. V zadnjih letih, ki jih zaznamujeta zmanjšan pomen multilateralizma in povečan pomen bilateralnih odnosov, je EU začela oblikovati svojo lastno zunanjo energetsko politiko (po moji oceni od 2015 dalje) in takoj, tako kot druge velesile, v svojo zunanjo energetsko politiko vnesla elemente dominantnosti. Neofunkcionalistična teorija, ki evropsko integracijo razlaga z učinkom prelitja, se je izkazala za uporabno tudi pri razlagi procesov oblikovanja zunanje energetske politike EU in povečane vloge in avtonomije Evropske komisije v tem procesu. Po teoriji Nye-ja o štirih stopnjah pri oblikovanju regionalne integracije EU trenutno prehaja iz tretje stopnje (redukcija alternativ) v četrto (eksternalizacija). Peto poglavje skuša pokazati kako je ameriška energetska politika skozi zgodovino doživela več sprememb. ZDA so si v začetku dvajsetega stoletja, tako kot mnogo let od krize v Sueškem prekopu sredi 70-ih let 20.stoletja, prizadevale za konkurenco, ki naj bi omogočila ustrezen dostop do virov energije s ciljem, da bi ohranile sprotno zadovoljevanje svojih energetskih potreb. Od sredine osemdesetih let je postala ameriška energetska politika bolj večstranska, z vedno večjo skrbjo glede okoljskih vprašanj, vendar sta varnost oskrbe in konkurenčnosti še vedno na prvem mestu. Medtem, ko je ameriško energetsko politiko v dvajsetem stoletju vodil strah pred pomanjkanjem energije, je tako imenovana nekonvencionalna revolucija pri pridobivanju plina in nafte iz škrilavcev v drugem desetletju enaindvajsetega stoletja spremenila odnos Washingtona do zunanje energetske politike in močno vplivala na mednarodne trge nafte in plina. Obdobje nenehno rastoče skrbi glede pridobivanja energetskih virov je tako nadomestila doba energetske obilnosti. V dobi energetske obilnosti v ZDA si je Trumpova administracija zastavila cilj, da ZDA postanejo energetsko dominantne. Zaradi tega je Trumpova administracija začela podpirati politične posege v kreacijo cen na naftnem trgu in odmik od multilateralizma, ki je poprej omogočal globalno konkurenco. Kljub temu, da so ZDA dosegle status največje svetovne proizvajalke nafte in plina, se zdi, da Washington še vedno ne odstopa od ciljev, ki jih tradicionalno zasleduje s svojo zunanjo energetsko politiko: zagotavljanje zalog na svetovnih naftnih trgih in zmanjševanje motenj pri dobavi ; spodbujanje zaveznikov, da diverzificirajo lastne energetske vire, kjer je bila Evropa v glavnem v središču prizadevanj ZDA ; in s svojo močjo kaznovati države izvoznice plina in nafte ter jim ukazati, naj spremenijo politike, z uporabo možnosti uvedbe sankcij. Uvajanje sankcij ima vse pomembnejšo vlogo v ameriški zunanji politiki, saj je vedno bolj vprašljivo, kdaj, in če sploh, uporabiti vojaško silo za politične cilje. Nova doba obilja energije ZDA omogoča, da k uvedbi sankcij pritegnejo tudi druge države ter jih tako skupaj lažje uvedejo koordinirajo. Po drugi strani pa je zelo verjetno, da bi odločitev ZDA, da izkoristijo svoj položaj energetskega dobavitelja in začnejo izvoz energije uporabljati v politične namene, lahko delovala proti njihovim lastnim interesom in zmožnosti doseganja njihovih zunanjepolitičnih ciljev. ZDA nikoli niso sodelovale v nobeni gospodarski organizaciji, ki bi omogočala prenos suverenosti glede energetske politike v roke neke nadnacionalne strukture in neofunkcionalizem v njihovi zunanji energetski politiki nima nobenega odmeva. Šesto poglavje, ki je posvečeno Rusiji, raziskuje, kako njena bogata baza energetskih virov zagotavlja davčno osnovo za državno porabo, devizne prihodke in vzvod (zlasti v primeru dobave plina) v mednarodnih odnosih. Zahvaljujoč visokim cenam nafte iz obdobja pred pandemijo COVID-19 je Rusiji uspelo obnoviti gospodarstvo in povečati svojo geopolitično trdnost. Zaradi izjemne odvisnosti od energetskih prihodkov za ruski državni proračun je neugodna kombinacija nizkih cen nafte in finančnih sankcij ZDA in EU skupaj z naraščajočo konkurenco v proizvodnji nafte in plina povzročila postopno zmanjševanje ruskega vpliva v mednarodni politiki. Rusija nima veliko možnosti, da bi v bližnji prihodnosti postala pomemben igralec na azijskih trgih. Tako se je država usmerila k širitvi in osvežitvi svojih energetskih vezi z Evropo. Kljub temu pa Moskva vzporedno s tem spodbuja svoj konkurenčni integracijski projekt Evroazijske ekonomske unije (EAEU), katerega namen je povsem nasproten cilju evropskih integracijskih projektov, po katerih se vsaj formalno zgleduje. S tem projektom želi Rusija, med drugim, v energetskem sektorju zaščiti svoj prevladujoči položaj v postsovjetskem prostoru. Kljub formalni podobnosti EAEU z EU tam ni mogoče pričakovati učinkov prelitja na nadnacionalni ravni v skladu s teorijo neofunkcionalizma, saj gre za združitev neenakopravnih partnerjev z močnim ruskim vodstvom, ki ne dovoljuje socializacije neke nove, nadnacionalne elite. Sedmo poglavje predstavlja kako je zaradi hitro rastočega gospodarstva in povečanega povpraševanja po energiji Kitajska povečevala vpliv na svetovnih energetskih trgih. Na energetsko politiko kitajske vlade je močno vplivalo vse večje povpraševanje po nafti in odvisnost države od uvoza le-te. Naftna in plinska industrija sta zaslužni za zagotavljanje oskrbe, za zadosten proračunski dohodek in tudi za delovna mesta. Kitajska državna podjetja skušajo svoje poslovanje prilagoditi svetovnim praksam, vendar je bil do sedaj njihov manevrski prostor vedno omejen z državnim nadzorom. Pod sedanjim vodstvom kitajska podjetja sodelujejo v mednarodnem prodoru z velikimi, neposrednimi naložbami. Prvi poskus takega prodora je bila iniciativa 16+1 (sedaj 17+1) [e pred sedanjim predsednikom Xi Jinpingom. Njegov prihod na oblast je sprožil še obsežnejšo iniciativo. Prosor v svetovnem merilu je bil pred kratkim zasnovan kot Iniciativa pasu in ceste (Belt and Road Initiative - BRI). Kljub temu, da v BRI sodeluje skoraj 70 držav, pomen iniciative ostaja nejasen. BRI zagotavlja zaščito kitajskih trgovskih poti in oskrbe z energijo ter omogoča državi, da svoje industrijske presežke in gradbene kapacitete učinkovito izvaža po vsem svetu. Z BRI kitajska zunanja politika prek gospodarske diplomacije poskuša povečati svoj vpliv. Ta projekt je treba razumeti kot dolgoročno, globalno iniciativo, ki nima samo gospodarskega cilja. BRI in iniciativa 17+1 sta še dve obliki mednarodnega sodelovanja, ki sta neprimerljivi s postopkom vključevanja v EU in v njiju zaradi dominantnosti Kitajske ni prelitja funkcij na nadnacionalno raven kot ga opisuje neofunkcionalistična teorija. ; In the study, I tried to explore how characteristics of energy supply in each of the four global superpowers (EU, US, Russian Federation, People's Republic of China) influences their foreign energy policy, which out of the three elements of energy policy (competitiveness, security of supply, sustainability) primarily reflects it and how and if different forms of foreign energy policy regional initiatives can be explained with the theory of neofunctionalism. The first chapter aims to present the neofunctionalist theory as a theory of regional integration. It first analyzes Jean Monnet's attempts for European integration, at that time illustrated by the European Communities: European Economic Community, Euratom and the European Steel and Coal Community. Later, it was further developed to be able to explain processes like territorial growth of a regional integrated area and also processes of its shrinking, i.e. Brexit. Neofunctionalism is a theory explaining the process of integration on a regional level with reference to growing reciprocal economic relationships in-between nations. It also analyzes capacity of a regional organization in dispute resolution and creation of international legal regimes, within which the supranational market rules may replace national regulatory regimes. It explains also integration by positive spillover effects as necessities to cooperate in sectors, which are indirectly related to the sector where regional cooperation first started. I briefly present also intergovernmentalism as an alternative theory. The first chapter also briefly presents 130 years of history of regulation to protect competiveness on energy markets, some 80 years of security of supply challenges and their translation into political decisions and some 70 years of history of creation of sustainability in modern energy policy. The second chapter presents the structure of energy supply and the market structure in each of the analyzed global superpowers. It is evident that energy markets (oil, gas, electricity) in the US and the EU are highly competitive and efficient. Both superpowers strive also towards sustainability and are constantly decreasing harmful emissions from fossil fuel power plants as well as transport and other energy consuming activities. While the EU is highly import dependent (in 2017 imported more than 55% of all energy sources), the United States in the last 15 years developed from the biggest importer of energy sources globally into a net exporter, reaching energy self-sufficiency in 2018. Russia has a net energy imports index at -84%. It is one of the biggest net exporters of oil (some 10% of global production) and gas (close to 20% of global production), according to data from 2014. In 2018, it exported almost the same amount of energy as was consumed in the country. Despite its energy abundance, Russia has heavily regulated and inefficient gas, oil and electricity markets. Among the four analyzed superpowers, it has far the least energy efficient use of its energy resources. The position of Gazprom, which enjoys a monopoly on pipeline gas exports to Russia's neighbors, has been increasingly challenged. Consequently, pressures on Moscow to reform its energy (particularly gas) sector have been rising. So far, the Russian government has shown reluctance with regard to implementing structural reforms in its energy sector and has rather been trying to adjust, react and adapt to created circumstances. China is slowly liberalizing its gas market. Reform that attracted new private investors into electricity generation in the 1990s has backslid. Gas, coal, electricity generation and oil sectors are primarily controlled by state-owned companies and do not allow much room for competition. China in 2017 consumed 22% of all energy sources globally and was by far the biggest energy consumer worldwide. China extracts and burns around half of all coal being extracted worldwide and is heavily unsustainable. Its harmful emissions from power plants remain high and stable, while CO2 emissions are in constant ascent. However, in recent years, the country has been focusing much more on services-based economy and renewable energy. Additionally, taking into account the combination of effects of factors like structural changes in the economy, growing efficiency within the energy industry and demographic changes, total growth of the energy demand up until the year of 2040 will be comparable to the one that China experienced from 2008 to 2016. Its net energy imports index is 15% and shows moderate dependence on import. The third chapter aims at analyzing the EU's emerging foreign energy policy in a global context of imperfect energy relations. Energy, being an increasingly politicized sector, still remains closely linked with state sovereignty and national interest. Consequently, Brussels's efforts to shape a coherent foreign energy policy, while sharing competences with the Member States and taking into account the carefully drafted compromise of article 194 of the Treaty on the Functioning of the EU, has proved to be increasingly challenging. Moreover, Europe, being highly dependent on foreign energy suppliers (among which Russia, with its contrasting vision of energy policy, plays the most important role) has been further undermining the EU's aspirations of introducing universal, market-based norms in global energy relations. Against this backdrop, the EU managed to make some achievements in its foreign energy policy, particularly, by the means of the European Economic Area and the Energy Community, which was a successful example of what Europe aspired to achieve globally. In recent years marked by the decreased role of multilateralism and the increased role of bilateral relations, also the EU introduced elements of dominance into its foreign energy policy despite opposition to such behavior when performed by other superpowers. The neofunctionalist theory explaining European integration by spillover effect has proven to be usable also in explaining processes of creation of EU foreign energy policy in the years from 2015 on and increased role and autonomy of the European Commission in it. The fourth chapter attempts to demonstrate that US energy policy has gone through multiple changes throughout history. While in the beginning of the twentieth century, the US pursued competitive access to energy sources to sustain the strong growth of its demand, after the Suez Canal crisis and the subsequent oil crisis in the mid-seventies, the US energy policy became centered on ensuring the security of supply. Since the mid-eighties, it became much more multi-sided, with growing concern about environmental issues, yet without detriment to the importance given to security of supply and competitiveness. While American energy policy throughout the twentieth century has been driven by fears of energy scarcity, the so-called unconventional revolution of the past decade changed Washington's attitude towards its foreign energy policy and also considerably impacted international oil and gas markets. An atmosphere of continuously growing competition for resources has, thus, been replaced by the age of energy abundance, where the Trump's US administration has set the objective of the United States becoming energy dominant, supporting political interventions into the creation of prices on the oil market and moving away from multilateralism, which enabled global competition. Despite the fact that the US achieved the status of being the biggest producer of oil and gas in the world, Washington does not seem to withdraw the objectives traditionally pursued by its foreign energy policy. Namely, ensuring supplies on the global oil markets and minimizing disruptions ; encouraging allies to diversify their own energy resources, where Europe has usually been the main focus of US efforts ; and using its power to punish countries and to command them to change policies, using the possibility of imposing sanctions on gas and oil exporting nations. With latest Biden's administration US seems to reposition its focus on sustainability and multilateral cooperation again. Despite that sanctions play increasingly important role in US foreign policy, since it is more and more questionable when and if at all to deploy military force. New energy abundant age enables the US to get on board other nations to collectively impose multilateral sanctions easier than in previous times. ON the other side it is very possible that US decision to become energy dominant and start using energy exports for political purposes could work against their interests and ability to achieve their objectives. The US never participated in any economic organization that would tend to transfer sovereignty over energy policy to a supranational structure. The fifth chapter dealing with Russia explores how its vast energy resource base provides the fiscal basis for state spending, foreign exchange earnings, and leverage (especially for gas) in international relations. Thanks to the high oil prices of the pre COVID-19 pandemic decade, Russia managed to recover its economy and increase its geopolitical assertiveness. Nevertheless, due to its extreme dependence on energy revenues, following the unfavorable combination of low oil prices, financial sanctions of the West combined with the rising competition in production resulted in Russia's gradually diminishing economic leverage. Russia, with unlikely prospects to become a prominent player in Asian markets in the foreseeable future, has turned to expanding and refreshing its energy ties with Europe. Yet, in parallel, Moscow has been pushing forward its competing integrationist project of the Eurasian Economic Union (EAEU), which aims to conflict and overlap with the European integrationist projects, inter alia, in the sector of energy in order to safeguard its dominant position in the post-Soviet space. Despite the formal similarity of the EAEU with the EU, there is no spillover effect since it is an association of unequal partners with strong Russian leadership. Country's fast-growing economy and rapid increase in energy demand has lead China to gain more influence in global energy markets. The energy policy of the Chinese government has been strongly influenced by the increasing demand for oil and country's dependence on oil imports. The oil and gas industry has remained a strategic asset for the Chinese government. This industry is responsible for ensuring supplies of oil and gas, for sufficient budget income as well as for employment. With closer integration into global markets, Chinese state-owned companies have been seeking to adapt their operations to global practices, yet, the room for maneuver has always been limited by state control. Under the present leadership, Chinese companies have been engaged in large-scale outward direct investments. This process was recently soon packed as a Belt and Road Initiative (BRI). The fact that nearly 70 countries are participating in the BRI does not improve the perception that its label remains unclear. There is still no exact definition of the qualification of a BRI project Yet, half a decade after the launch of one of the most ambitious geo-economic projects of recent history, some more things became clearer. To name a few, BRI is not only responsible for securing China's trade routes and energy supplies, it is also accountable for the fact, that the country is being able to export worldwide several construction projects due to its industrial overcapacities. The BRI became a major component of China's grandiose foreign policy agenda aimed at increasing Chinese influence in the BRI region and beyond. The past years have proven that the BRI project is to be understood as a long-term, global and not having only an economic goal. Yet, challenges regarding to the future success of the BRI are many and of different nature: technical, political, financial and regulatory, to name a few. Both suspicion and skepticism concerning its real motives and viability remain high, especially among those countries who have been the main designers of today's global financial system and international trade rules. The Belt and Road Initiative is yet another form of international cooperation which is incomparable with the EU integration process and neofunctionalist theory cannot be used for its explanation. The thesis confirmed that characteristics of energy supply in a country are directly and with the same attitude reflected in the foreign energy policy. Foreign energy policy is additionally held up by whichever tool of dominance being available to one of the four studied cases. The thesis also confirmed that Haas' theory of neofunctionalism is still supportive in explanation of regional integration of all initiatives proposed in and by the four global superpowers. EU is creating its own foreign energy policy entering externalization as the last, fourth stage of regional cooperation, according to Nye.

Untersuchungen zur Rohstoffeffizienz der Forst-Holz-Kette vor dem Hintergrund der Forstreform in Ghana Im Jahr 1994 wurde in Ghana eine Forstreform durchgeführt, mit dem Ziel, das Artenspektrum der kommerziell nutzbaren Bäume zu vergrößern, den Holzverlust in der Forst-Holz-Kette zu reduzieren sowie die Verarbeitungsprozesse in der Holzindustrie zu optimieren. Um den Erfolg dieser politisch motivierten Ziele sicherzustellen, wurden ein Exportverbot für Rundholz und Mindestpreise für den Verkauf von Holz auf dem Stock erlassen, die an die internationalen Marktpreise angepasst waren. In dieser Arbeit soll die Effizienz dieser Maßnahmen genauer beleuchtet werden. In einem ersten Abschnitt werden die Auswirkungen des Exportverbots von Rundholz (LEB=log export ban) ab 1995 auf die weiter verarbeitende Industrie, die Preisentwicklung auf nationaler und internationaler Ebene sowie die Nutzung des vorhandenen Artenspektrums mit statistischen Methoden untersucht. Dafür standen zwei Zeitreihen der Timber Industry Development Division (TIDD), einer Abteilung der Forstkommission von Ghana, zur Verfügung. Der erste Datensatz umfasst den Zeitraum von 1984 bis 2005, während der zweite, detailliertere Datensatz die Periode von 1995 bis 2005 abdeckt. Im zweiten Abschnitt der Arbeit wurde die bei Holzerntemaßnahmen erzielte Rundholzausbeute analysiert. Dazu wurden im Rahmen von Fallstudien Holzerntemaßnahmen mit detaillierten Untersuchungen begleitet. Verglichen wurden die aufgrund der Dimension und der Qualität der eingeschlagenen Bäume verwertungstechnisch objektiv nutzbaren Holzmengen mit denjenigen Rundholzmengen, die tatsächlich zur Verarbeitung gelangten. In die Untersuchung wurde die Kontrolle und Ausführung der Arbeit miteinbezogen. Aus den Ausbeutedaten wurden Modelle zur Berechnung eines angemessenen Stockpreises sowohl für einzelne Baumarten als auch als Durchschnittswerte entwickelt. Ein weiterer Arbeitsschritt befasste sich mit der Schnittholzausbeute im Sägewerk. Ebenfalls im Rahmen von Fallstudien wurden das eingesetzte Rundholz und das daraus erzeugte Schnittholz hinsichtlich Volumen und Qualität verglichen und die Gründe für Ausbeuteunterschiede analysiert. Die Analyse des Produktionsprozesses deckte dabei auf, welche Faktoren bei welchen Arbeitsschritten zu den beobachteten Verlusten bei der Schnittholzausbeute beitragen. Dabei wurden sowohl technische Faktoren als auch Motivation und Ausbildungsstand der Arbeiter berücksichtigt. Auswirkungen des Exportverbots – Entwicklung der Exportmengen In dem Zeitraum vor Inkrafttreten des Rundholzexportverbots in den Jahren 1984 bis 1985 betrug das Gesamtexportvolumen von Holz und Holzprodukten ca. 5,7 Mio. m³. Daran hatten Rundholz- und Sägeholzexporte einen Anteil von 55% bzw. 39%, während die Anteile von veredelten Produkten deutlich niedriger waren: Furnier 4,1%, Sperrholz 0,4% und Fertigwaren aus Holz 1,4%. In den Jahren zwischen 1996 und 2005, in denen sich das Rundholzexportverbot auswirkte, betrug das exportierte Gesamtvolumen von Holz und Holzprodukten 4,5 Mio. m³. Daran hatte das Sägeholz einen Anteil von 54%, während der Anteil weiterverarbeiteter Produkte deutlich zunahm: Furnier 21,3%, Sperrholz 10,5% und Hobelware bzw. Holzprodukte 14,2%. Die Analyse der Wirkung des Exportverbots für Rundholz aus Ghana zeigt, dass durch diese Maßnahme ein deutlich höherer Anteil der Wertschöpfung im Land verbleibt. Vor allem die Herstellung von Furnieren, Sperrholz und veredelten Holzprodukten stieg deutlich an. In dieser Hinsicht wird die Hypothese gestützt, dass ein Exportverbot von Rundholz die Produktion von höherwertigen Waren im Inland fördert. Weitere Faktoren für die beobachtete quantitative Zunahme und den Wertzuwachs bei den verarbeiteten Produkten dürften auch die Verknappung des Rundholzangebots, die hohen Exportzölle auf Halbfertigwaren (Sägeholz) und finanzielle Investitionsanreize seitens des Staates sein. Preisentwicklung für Exportprodukte Die Untersuchung zeigte, dass der aggregierte Preisindex für alle Holzprodukte, die vor Inkrafttreten des Rundholzexportverbots exportiert wurden, in der Zeit von 1984 bis 1995 inflationsbereinigt um 129% anstieg, während der aggregierte Preisindex nach Inkrafttreten des Rundholzexportverbots im Zeitraum von 1996 bis 2005 um 3% fiel. Dabei stiegen die Exportpreise für die verschiedenen Produkte in unterschiedlichem Ausmaß: Sägeholz um 109%, Furnier um 238%, Sperrholz um 142% und verarbeitete Holzprodukte um 102%. Im Zeitraum nach Eintreten des Rundholzexportverbots ergaben sich demgegenüber folgende Veränderungen in den Preisen: Sägeholz +14,8%, Furnier -21,9%, Sperrholz -47% und verarbeitete Holzprodukte -31,7%. Während die Exportpreise für Furnier an stärksten anzogen, fielen die Preise von Sperrholzprodukten aus tropischen Hölzern, da billige Sperrhölzer auf Nadelholzbasis den Markt eroberten. Auch der stetig ansteigende Einsatz von Holzwerkstoffen wie MDF und OSB im Möbelbau und im konstruktiven Bereich verdrängen tropische Sperrhölzer aus dem Markt. Ein weiterer Grund ist schließlich der starke Konkurrenzdruck auf diese Produkte durch Sperrholz aus chinesischer Produktion. China war bis vor kurzem noch ein wichtiger Importeur von tropischem Sperrholz, ist heute aber bereits einer der größten Exporteure. Die Ursachen für die Preisrrückgänge sind vermutlich auch in globalen Ereignissen zu sehen, wie beispielsweise dem Zusammenbruch der asiatischen Märkte in den Jahren 1997 und 1998, sowie der schwachen Nachfrage nach Waren auf internationalen Märkten zwischen 2000 und 2001, die u. a. aus der wirtschaftlichen Rezession der drei stärksten Volkswirtschaften (USA, Japan, Deutschland) resultierte. Anteil weniger genutzter Baumarten (LUS) Der Anteil der weniger genutzten Baumarten (LUS – lesser used species in Ghana, auch als "Pink" und "Green"-Baumarten bezeichnet) an der Exportmenge blieb auch während des Exportverbots für Rundholz relativ gering. An der Gesamtexportmenge (ca. 4,1 Mio. m³) der sechs Hauptprodukte, die zwischen 1995 und 2005 aus Gahana ausgeführt wurden, betrug der Volumenanteil der "Pink" und "Green" Baumarten nur 12,5% bzw. 1,3%. Die marktgängigen "Scarlet" und "Red"-Baumarten nahmen dagegen einen Mengenanteil von 49% bzw. 29,4% ein, während sonstige Baumarten zu 7,7% beitrugen. Detaillierte Analysen der Statistiken zeigen, dass veredelte Produkte wie Fußböden und Paneele nahezu vollständig aus "Scarlet" und "Red"-Baumarten hergestellt wurden. Der Anteil dieser Baumarten macht bei diesen Produktgruppen 87% bzw. 90% aus. Beide Produktgruppen gehören zu den höchstbezahlten Exportprodukten. In der Regel fordern Kunden und Verbraucher die spezifischen Holzeigenschaften dieser Holzartengruppen, woraus die hohen Anteile bei den hochwertigen Produkten zu erklären sind. Es steht zu erwarten, dass diese Holzarten auch in Zukunft in Produktgruppen dominieren. Wie erwartet, hat der Mengenanteil von luftgetrockneten Sägeholz aus "Scarlet" Baumarten von 83 % im Jahr 1995 auf etwa 6 % im Jahr 2005 abgenommen, während luftgetrocknetes Schnittholz aus den weniger genutzten "Pink"-Baumarten gegenläufig von 6 % im Jahr 1995 auf 22 % in 2005 anstieg. Die Substituierung von "Scarlet" durch "Pink" Baumarten spiegelt die zunehmende Knappheit dieser verwertungstechnisch geschätzten Baumarten wieder. In den letzten Jahren wurden durch die Forstverwaltung erhöhte Abgaben auf einfaches, luftgetrocknetes Schnittholz erhoben, welches aus den zunehmend knapper werdenden Hauptbaumarten hergestellt wird. Auch darin könnte die wachsende Bevorzugung der weniger genutzten Baumarten in diesem Produktbereich erklärt werden. Entgegen der Erwartungen blieb jedoch der hohe Anteil der Hauptbaumarten im Bereich des kammergetrockneten Sägeholzes stabil. Die Bevorzugung der "Scarlet" Baumarten für diese Produkte ist nicht zuletzt auf deren deutlich besseres Verhalten bei der künstlichen Trocknung zurückzuführen. Forschungsvorhaben und verbesserte praktische Erfahrungen über die technische Trocknung der bisher weniger genutzten Baumarten könnten dazu beitragen, dass auch in diesem höherwertigen Bereich zunehmend eine Substitution stattfindet. Ausbeuteverluste und mögliche Ursachen in der Forst- Holz-Kette Die Frage der Ausbeuteverluste und ihrer möglichen Ursachen entlang der Forst-Holz-Kette wurde methodisch im Rahmen eines Fallstudien-Ansatzes untersucht. Dazu wurden die Nutzungsgebiete von drei unterschiedlichen Konzessionären (A, B, D) ausgewählt, die von ihrer geographischen Lage und ihrer Struktur her für die primäre Holzverarbeitung durch die Industrie in Ghana typisch sind. Insgesamt 135 Bäume aus neun Baumarten wurden für diese Studie ausgewählt. Dabei handelt es sich um die für die Vermarktung bedeutendsten Baumarten. Das theoretisch holzindustriell verwendbare Volumen aller Bäume in dieser Studie belief sich auf 2.177 m3, d. h. im Durchschnitt 16 m3 je Baum. Tatsächlich aufgearbeitet und zum Sägewerk transportiert wurden jedoch nur 1.638 m3 oder 12 m3 je Baum. Damit betrug die durchschnittliche Ausbeutequote 75+/-11,82%, während gut 25% (539 m3) des an sich industriell verwendbaren Holzes als Hiebsreste im Wald verblieben. Sowohl der Zopfdurchmesser als auch die Länge dieser Reststücke, wie auch ihre Qualität wären durchaus für eine weitere Bearbeitung im Sägewerk geeignet gewesen. Während der Feldaufnahmen konnten ungenügende Arbeitstechniken und mangelhafte Überwachung als die wichtigsten Gründe für diese geringe Rundholzausbeute identifiziert werden. Dabei spielt auch die herrschende Praxis, nach der der Stockpreis ermittelt wird, den die Firmen an den Staat entrichten müssen, eine Rolle: Da nur für das tatsächlich aus dem Wald exportierte Holz gezahlt werden muss, ergibt sich für die Konzessionäre kein finanzieller Anreiz dafür, die gefällten Bäume möglichst vollständig industriell zu nutzen. Aus diesem offensichtlichen Missstand wurde die Notwendigkeit abgeleitet, Modelle zu entwickeln, die zur Bestimmung der gesamten potentiell vermarktbaren Holzmenge eines stehenden Baumes herangezogen werden können, um so den Stockpreis (stumpage fee) rechnerisch zu bestimmen. Auf der Basis der Versuchsergebnisse wurden drei allometrische Funktionen berechnet, die für eine Schätzung des nutzbaren Volumens herangezogen werden können. Für die Bildung von baumartenspezifischen Modellen wurden drei in Ghana vom Mengenaufkommen her wichtige und markgängige Baumarten herangezogen: Akasaa (Chrysophyllum albidum), Wawa (Triplochiton scleroxylon) und Ofram (Terminalia superba). Darüber hinaus wurden auch generelle Modelle ohne spezifischen Bezug auf einzelne Baumarten entwickelt. Als Datengrundlage dafür wurden neben den drei genannten Hauptbaumarten die Arten von neun weiteren Baumarten herangezogen. Im Allgemeinen hatten artenspezifische Modelle eine bessere Vorhersagbarkeit als gemischte Modelle. Der Grund könnte in der höheren Homogenität der beobachteten und der vorhergesagten Variablen bei den artenspezifischen Modellen liegen. Die Modelle, die auf der Basis der Variablen Brusthöhendurchmesser (DBH) und kommerziell nutzbarer Schaftlänge (L) die nutzbare Holzmenge schätzen, waren jenen Modellen überlegen, die als Variable lediglich den DBH heranziehen. Allerdings ist eine zutreffende Ermittlung der kommerziell nutzbaren Schaftlänge stehender Bäume in der Praxis schwierig. Auch die nur auf dem DBH basierenden Modelle konnten die sägefähigen Stammholzanteile einschließlich stärkerer Kronenanteile mit hinreichender Genauigkeit schätzen. Ein so genanntes Log-Tracking-System, das in Ghana eingeführt werden soll, könnte die Anwendung dieser Modelle in der Praxis begünstigen. Wenn mit ihrer Hilfe die tatsächlich genutzten Stammvolumina zuverlässiger als bisher ermittelt werden, kann mittels der entwickelten Modelle auf das reale, nutzbare Volumen der Bäume auf dem Stock zurückgeschlossen werden, und eine realistische Bestimmung des Stockgeldes (stumpage fee) wäre so möglich. Die Nutzung der entwickelten Modelle in der Praxis zur Festsetzung eines realistischen Stockpreises haben jedoch ihre Grenzen: Wenn sich im Zeitablauf die Ausbeuterelationen fundamental ändern, müssen durch aktuelle Untersuchungen die hier aufgestellten Modelle neu parametrisiert werden. Ausbeuteverluste und mögliche Ursachen im Sägewerk Um die Ausbeute von Schnittholz in der weiteren Bearbeitungsstufe zu bestimmen, wurden im Rahmen der Fallstudie in 4 Sägewerken (A, B, C, D) insgesamt 189 Stämme eingeschnitten. Dazu wurden folgende, für Ausbeute und Qualität ausschlaggebende Faktoren aufgenommen: • Dimension und Volumen des eingesetzten Rundholzes • Zeitraum zwischen Fällung und Verarbeitung der Stämme • Risse, Fäule, Pilzbefall und sonstige Fehler am Rundholz • Schnittbild • Einschnitttechnologien • Qualität des Einschnitts (Maßhaltigkeit) • Volumen und Qualität des erzeugten Schnittholzes Die durchschnittliche Schnittholzausbeute lag bei 28,3% und war damit deutlich niedriger als die in vergleichbaren Studien angegebenen Werte. Die Ausbeute schwankte zwischen nur 1,9% für die Baumart Otie (Pycnanthus angolensis), die im Sägewerk A eingeschnitten wurde, bis hin zu 52.6% für Mahagonie (Khaya ivorensis), eingeschnitten in Werk B. Es konnte festgestellt werden, dass die geringe Qualität und die hohen Materialverluste überwiegend auf die lange Lagerzeit zwischen Fällung und Einschnitt zurückzuführen waren. Alle Otie-Stämme (Pycnanthus angolensis) und die meisten der Wawa –Sägestämme (Triplochiton scleroxylon) zeigten tiefe Risse an der Stirnseite sowie starken Pilzbefall, was zu hohen Ausbeuteverlusten führte. Für die Baumart Otie (Pycnanthus angolensis) wurden durchschnittliche Zeiträume von 6 Monaten vom Einschlag bis zum Einschnitt ermittelt, für Wawa immerhin noch 4 Monate. Eine entscheidende Schwachstelle ist also die mangelhafte logistische Planung. Die unflexible Ausrichtung in der Schnittholzproduktion auf nur wenige exportgängige Liefermaße verursachte einen hohen Volumenanteil an Sägeresthölzern, die bei einer entsprechenden Einschnittgeometrie und Sortierung durchaus zu Fußböden, Paneelen oder anderen Produkten hätten weiterverarbeitet werden können. Um die Maßhaltigkeit der verwendeten Einschnitttechnologien zu bestimmen, wurden zusätzlich an 267 Brettern in sägefrischem Zustand Breite und Stärke ermittelt. Die Ergebnisse der Studie zur Maßhaltigkeit des Schnittholzes weisen darauf hin, dass veraltete und schlecht gewartete Sägentechnik für große Volumenverluste beim Einschnitt verantwortlich sind. Schwankungen der Maßhaltigkeit von 2 bis 17% innerhalb eines Brettes konnten bei der untersuchten Schnittware festgestellt werden. Die Streuung der Maßhaltigkeit zwischen den Brettern war signifikant höher, was wiederum eine schlechte Wartung bzw. Justierung der Einschnittaggregate bestätigt. Abschließend muss kritisch angemerkt werden, dass mit 4 Fallstudien der Stichprobenumfang bei der Bestimmung der Einschlagvolumina sowie der Ausbeuteuntersuchungen bei Schnittholz im Sägewerk keine statistisch repräsentativen und auf ganz Ghana verallgemeinerbare Aussagen zulassen. Dennoch sind die Ergebnisse insofern richtungweisend, als dass Ursachen und Faktoren für die hohen Material- und Wertverluste entlang der Forst-Holz-Kette in Ghana aufgezeigt werden. Damit können Lösungsansätze für die logistischen und technischen Probleme erarbeitet, ein effizientes Controlling konzipiert und innovative Ansätze für eine erweiterte Produktpalette entwickelt werden. Diese Maßnahmen sind dringend notwendig, um eine nachhaltige Bewirtschaftung der Naturwälder Ghanas sicherzustellen und den knappen Rohstoff Holz effizienter zu nutzen. ; SUMMARY: Assessment of raw material utilisation efficiency of the forest-wood chain as influence by the forest sector reform in Ghana. The 1994 forest sector reform in Ghana placed priority on downstream processing, utilisation of lesser-used species (LUS) and improvement of processing efficiency in the timber industry of Ghana. To ensure the success of these policy goals, a ban on exportation of logs was introduced and stumpage fees were adjusted to reflect the realistic timber prices on the international market. This thesis was designed to assess the raw material utilisation efficiency under the influence of the forest sector reform and forest-wood processing chain. The thesis set out to investigate the effects of the log export ban (LEB) policy on the downstream processing, the growth of volume and the prices of the export wood products, and the utilisation of the various timber species. Two sets of time series data as compiled by the Timber Industry Development Division (TIDD) of the Forestry Commission of Ghana were analysed with statistical regressions. The first set of data spanned from 1984 to 2005 whilst the second more detailed data set was compiled from 1995 to 2005. This thesis further assessed, on a case study basis, logging recovery and examined the effect of lax supervision on the logging recovery, and thus justifying the need to develop models to predict the total merchantable volume and logically, the realistic stumpage volume and fees. It continued to assess the sawnwood processing recovery and quantified the volume loss due to sawnwood thickness over-sizing and sawing variation and investigated other factors that contribute to the low sawnwood recovery so as to provide managers and operators with insight into their operation performance and identify ways to improve production. Export market- Volumes Before the LEB policy in the years from 1984 to 1995, the total export volume of wood and wood products was about 5.7 million cubic metres. Out of this volume, log and sawnwood exports accounted for about 55 % and 39 % respectively whilst the contributions from veneer, plywood, and processed wood exports were 4.1 %, 0.4 % and 1.4 % respectively. In the years between 1996 and 2005, the total volume of wood and wood products exported during the LEB policy was about 4.5 million cubic metres. Veneer, plywood, and processed moulding showed increasing shares in the export market, contributing respectively 21.3 %, 10.5 % and 14.2 % during this period, whilst sawnwood accounted for 53.9%. The results of the study showed that the implementation of the log export ban policy in Ghana caused increases in the volume shares of the value-added products such as veneer, plywood and processed wood, which is in agreement with the theory that an LEB policy stimulates the production of value-added products. However, important factors such as shortage of timber supply, high export taxes on the primary products (sawnwood), and investment incentives may have played significant roles in increasing the volume of these products. Export market- Prices The study found that the aggregate price index of all the wood products exported before the LEB policy increased by 129 % compared to the decline of the aggregate price index by -3.9 % during the LEB policy. The growth in the export prices of sawnwood, veneer, plywood and processed wood before the LEB policy were respectively 109 %, 238 %, 142 % and 102 % compared to the corresponding growths or declines of 14.8 %, -21.9 %, -47 % and -31.7 % during the LEB policy. Whilst the export prices of veneer appear to have been bolstered by the increasing market share of re-constituted panels such as MDF and OSB, those of plywood from the tropical forests were eclipsed by the increasing substitution of tropical plywood by softwood plywood and other panels such as MDF and OSB in furniture, millwork, and mouldings production. Another important contributing factor to the decline in the prices of plywood is the intense competition from China, which until recently was a major importer of tropical plywood, and is now a major exporter of plywood. The need to find new markets for tropical plywood could help revive its export trade. These decline in prices also appears also to have been caused by such global factors as the collapse of the Asian economy in 1997 and 1998, and the weak demand for international commodity in 2000 and 2001, resulting from the economic recession of the world's three largest economies (U.S.A., Japan and Germany). Export volume of the traditional (scarlet and red) and the Lesser-Used Species (LUS) (pink and green) species During the LEB policy, the export volume shares of the LUS (pink and green species) stayed relatively low. Out of the total export volume of 4,074,570 m³ of the six main products exported from 1995 to 2005, pink and green species (LUS) contributed only 12.5 % and 1.3 % respectively. Furthermore, scarlet and red species had a respective volume share of 49 % and 29.4 % whilst "other species" contributed 7.7 %. The results indicated that flooring and moulding products were almost exclusively produced from the traditional timber species. About 87 % of the flooring and 90 % of the moulding products were produced from both the scarlet and red species. These two products are among the highly-priced export products. The flooring and moulding products are generally used for decoration purposes and the traditional and highly-valued timber species such as the scarlet and red species are expected to dominate the choice of species for these products. This fact probably explains the high volume contribution of the traditional timber species to the production of flooring and moulding products. In the face of a limited supply of the primary timber species, scarlet and red species obviously should be reserved for the highly-priced products such as flooring and moulding. As expected, the trend in the volume share of air-dried (AD) sawnwood produced from the scarlet species showed a substantial decrease from 83 % in 1995 to about 6 % in 2005, whilst air-dried sawnwood from the pink species increased from about 6 % in 1995 to about 22 % in 2005. The substitution of the scarlet species by the pink species reflects the increasing shortage of supply of the former. Another reason could be the result of systematic efforts by the stakeholders in forest management in Ghana to substitute the LUS species for the scarlet in the production of sawnwood (AD) by imposing levies on sawnwood (AD) produced from the primary timber species. Contrary to expectation, kiln-dried (KD) sawnwood had the most stable volume share from the scarlet species, decreasing only marginally from about 86 % in 1995 to about 84 % in 2005. Technical difficulties in developing kiln-drying schedules for the LUS species may explain a higher percentage volume share of the scarlet species used to produce sawnwood (KD). The logging efficiency and the development of allometric models to predict the realistic stumpage volume In a case study approach, a total of 135 trees from nine timber species were sampled from three logging sites of mills A, B and D to allow for the assessment of logging recovery and the development of models to predict the total merchantable volume. The mills were selected according to the prevailing sawmill industry structure in Ghana. The main species were selected on the basis of their forest availability and economic importance. Wawa (Triplochiton scleroxylon), for example, constitutes about 21 % of Forest Inventory Project (FIP) class 1 volume greater than 70 cm in diameter (see Ghana Forestry Department 1989) and hence justifies its higher selection percentage. The merchantable volume of all the trees sampled from the three studied mills totalled 2,177 m³, averaging 16.0 m³ per tree. The logs that were extracted from this total merchantable volume by the mills amounted to 1,638 m³, averaging 12 m³ per tree. The average logging recovery rate of the three studied logging sites was 75±11.82 % whilst 25 % (539 m³) of the merchantable volume was left at the logging site as residues. On the basis of the small-end diameter and length values, the merchantable wood residues were of sufficient quality to warrant their utilisation. For example, the small-end diameter of the residues ranged from 41 cm for ofram (Terminalia superba) to 60 cm for wawa (Triplochiton scleroxylon) whilst the average length of the residues also varied between 4.2 m for sapele (Entandrophragma cylindricum) and 8.5 m for wawa (Triplochiton scleroxylon). The study identified insufficient working techniques and lax supervision as one of the major causes of low logging recovery and the existing practice of fixing stumpage fees gives only weak economical incentives to improve volume recovery. Therefore the need to develop models to predict the total merchantable volume as a basis for adjusted stumpage fee calculation, was justified. To fix realistic stumpage fees, which take into account the true potential of the harvested trees, three allometric equations were developed to allow for comparison in terms of predictive accuracy. Three main species, namely akasaa (Chrysophyllum albidum), wawa (Triplochiton scleroxylon), and ofram (Terminalia superba) were sampled for the construction of the species-specific based models. The mixed-species based models were developed from the three main species and six additional tree species. In general, the species-specific models had a better predictive power than the mixed-species based models and this could be attributed to the relatively higher homogeneity of both the observed and predictor variables of the species-specific based models. Among the mixed-species based models, those that predicted the total merchantable volume indirectly from the log volume had the highest predictive power. The log tracking system which is being introduced in Ghana could benefit from these models. When logging data are available (through the log tracking system) the models could be used to predict the realistic stumpage volume. These models however, were found to perform relatively better for small-sized trees than for large-sized trees over (20 m³). The models that predicted the total merchantable volume from DBH and the total merchantable length had better fits than those that used only DBH as a predictor variable. Nevertheless they have little practical importance because of difficulty in measuring the total merchantable length in the forest. These models have however theoretically showed that, by including the merchantable branches, the general form of allometric equation did not substantially change. DBH as a predictor of the total merchantable volume has several advantages. It is easier and simpler to use since forest inventories include DBH measurements. For the mixed-species based models that predicted the total merchantable volume from DBH only, the site-specific models had a higher predictive power than a single model developed for all-sites, indicating that for a higher accuracy, DBH may be a good predictor of the total merchantable volume of tree species at a specific site. The use of these models, however, presents a limitation. If logging efficiency of individual mills changes substantially over time, the model may have to be validated periodically before it could be applied. Sawmill efficiency In order to determine sawnwood recovery in a case study approach, a total of 189 saw logs were sampled from four mills (Mills A, B, C and D). In order to assess the factors that affect sawnwood recovery, the following inquiries and observations were made and recorded: • Log dimensions (length, diameter at both ends) • Time between felling and processing of logs, • Prior to processing, each sampled saw logs was inspected for defects such as end-splits, rots and fungal blue stain. • Log breakdown technique, • Edging and trimming techniques and • Quality of trimming off-cuts The average sawnwood recovery (28.3 %) found in this study was substantially lower than the reported average recovery rate in the previous studies. The sawnwood recovery ranged from 1.9 % for the otie (Pycnanthus angolensis) processed at mill A to 52.6 % for the mahogany (Khaya ivorensis) processed at mill B. The study found that the poor log quality, resulting mainly from long storage periods between felling and processing, had a substantial effect on the sawnwood volume recovery. All of the otie (Pycnanthus angolensis) saw logs and most of the wawa (Triplochiton scleroxylon) saw logs sampled had end-splits and were severely infested with fungal blue stain and thus their low recovery was expected. The low sawnwood recovery reported in this study could be mainly attributed to a lack of proper management of logs and a lack of adequate logistic planning. For example, the period between felling and processing of the otie (Pycnanthus angolensis) logs was about six months whilst due to logistical problems and poor planning the period between felling and processing of the wawa logs sawn at mill D was about three months. In addition, 267 green sawn boards were sampled from the mills to quantify the sawnwood volume loss due to thickness over-sizing and sawing variation. The results of this study indicated that the volume that could have been gained by reducing the sawnwood thickness over-sizing and sawing variation ranged from about 2 % to 17 % in volume of the sampled sawnwood. The study also found that between-board sawing variation was substantially higher than within-board sawing variation indicating that lack of setworks repeatability could be the major cause of the loss in volume. It was observed that the studied mills concentrated their production on sawnwood in export dimensions and grades. Therefore, off-cuts and trim ends that could have been processed further into mouldings, battens, floorings, and other products were discarded or sold at cheaper prices. The limited supply of timber resources give every reason for sawmills in Ghana to optimise fibre recovery from every tree that is felled. Even though this thesis studied only a limited number of cases, which represent a small fraction of the forest and sawmill industry in Ghana, there is a reason to believe that conditions prevailing in other operations are not very different from those observed in these case study mills. Ghanaian sawmills stand to benefit economically if they could improve their logistical planning and integrate production lines devoted to recovering fibre from off-cuts and trimmings.

This study investigates the impact of various government interventions on the spread of COVID-19 as well as stock markets in South-East and East Asia. It finds that stricter interventions – including gathering restrictions, public event cancellations, and mask requirements – helped mitigate the severity of the pandemic significantly in the region. Total border closures had a moderate effect on flattening COVID-19 spread, especially during the onset of the pandemic. Other policies, such as school closures or stay-at-home orders, worked effectively later in the pandemic. The study also shows evidence of herding behaviours in regional stock markets during the pandemic. School closures, gathering restrictions, stay-at-home orders, domestic travelling bans, robust testing policies, and government income support programmes tended to reduce herding behaviour. More stock market integration is found during the onset of the pandemic, compared to the periods before and later in the pandemic, implying the short-term impact of a sudden shock from COVID-19.

The multidonor Gender and Development Cooperation Fund (GDCF) was established in May 2003 as a facility to promote gender equality and women's empowerment in the Asia Pacific region. This facility will help facilitate effective implementation of the Asian Development Bank's Policy on Gender and Development and accelerate gender equality and women's empowerment in the Asia Pacific region. As a leverage fund, GDCF is intended to make ADB's operations work better for gender equality and women's empowerment in Asia and the Pacific. Activities supported by GDCF are all aimed at influencing much bigger loan and Asian Development Fund (ADF) projects, national laws and sector policies, and capacity of ADB's clients in implementing such projects and policies.
