Over the last 50 years there has been a paradigmatic shift in the climate of ideas and governing orthodoxy from Keynesian-corporatism to neoliberalism. Such paradigms provide the philosophical goals that are pursued by policy and practice and determine what are considered to be the legitimate means of attaining those goals. We use evolving policy and practice relating to the protection and management of street trees as a vehicle for examining the relations between the competing paradigms of corporatism and neoliberalism, and the ways that they are expressed 'on the ground'. In doing so we highlight the tensions between the amenity value and the economic value of street trees and between techniques for their estimation. The legitimacy of measures of the former, such as Helliwell and CAVAT, that embody corporatist concepts are subject to continuing challenges based on their (lack of) scientific rigour or economic principle. The strengths of measures of the latter, such as i-Tree, are emphasised on the same grounds. Such is the success of these efforts that the equation of the value of a street tree with an estimation of the price that people will pay for the ecosystem services it delivers is not seen as controversial.

ABSTRACT Human life is increasingly developing, making demands for fulfilment of needs are also growing. Likewise with the clothing needs used. Nowadays the use of one's clothing shifts into a lifestyle that cannot be separated from it. This condition can benefit the market to make it an opportunity. This happens in Indonesia, where the country whose population is the largest Moslem religion up to 85% of the total population has a fashion style that is influenced by the beliefs adopted by Islam. This fashion industry has an important role as a contributor to improving the economy. The development of the domestic Muslim fashion industry will be able to answer domestic to international market demand if it can formulate strategies in answering the challenges that exist. In this case the actors who play a role in the Muslim Fashion Industry must have a reliable strategy that can improve the development of the Muslim Fashion Industry. This development has also become the main focus of the Indonesian government where it has a target that makes Indonesia the World Muslim Fashion Qibla in 2020. By utilizing the wealth of Indonesian Human Resources, Nature and Culture, Indonesia will be able to reach its dreams. The impact that will be felt in achieving this target is very large, such as increasing economic productivity, increasing employment opportunities, national income and the role of Indonesia in the development of world Muslim fashion.

This study aims to discuss the understanding of hadith about the value of money in the perspective of Islamic economics. This research applies a qualitative type through literature study using thematic, takhrij, and syarah hadith methods as well as descriptive analysis. The discussion of this research includes an overview of money, thematic hadiths regarding money, and an understanding of the hadith about the value of money from an Islamic economic perspective in the contemporary era. This study concludes that the money used by Muslims at the time of the Prophet was Persian silver dirhams and Roman gold dinars, traditions about money are known to be maqbul traditions and can be used as evidence, and the understanding of hadiths about the value of money is closely related to buying and selling and selling. an effective prohibition of usury for controlling inflation so that people's purchasing power is maintained and economic stability is created, in this case Islamic economics which emphasizes increasing people's welfare is recognized in this contemporary era dealing with money politics with the ideology of capitalism.

Inclui correções e alterações sugeridas pelo Júri. ; The COVID-19 pandemic is the disaster of the 21st century, the disease that shook the world and change life of entire populations. Its tremendous negative impact on economy caused permanent changes in organizational functioning, triggering companies to create crisis management strategies and adopt new innovative practices. The agro-sector was not an exemption. Considering that this sector manifests constant growth related to not only the increase of human population, but also to continuous life-style changes, it is crucial to develop recovery strategies on organizational and governmental levels. Therefore this study provides the general overview of crisis management concept with its main characteristics and frameworks; analyses the importance of innovation in agro-sector; offers agro-sector overview; examines the pandemic's impact on this particular sector and some of the recovery strategies; and explores the attitudes of agro-sector professionals towards COVID-19 crisis in two countries – Portugal and Russia. This research intends to discover differences and similarities in crisis management solutions between agro business professionals in both countries, as well as possible approaches to crisis outcome minimization. ; A pandemia COVID-19 é a tragédia do século XXI, a doença que abalou o mundo e mudou a vida de populações inteiras. O seu forte impacto negativo na economia provocou mudanças permanentes no funcionamento organizacional, levando as empresas a criar estratégias de gestão de crise e a adotar as novas práticas inovadoras. O setor agrícola não foi a exceção. Visto que este sector demonstra um crescimento constante relacionado não apenas com o aumento da população a nível mundial, mas também com as mudanças contínuas no seu estilo de vida, um desenvolvimento de estratégias de recuperação a nível organizacional e governamental torna-se imperativo. Deste modo, este estudo oferece um panorama geral do conceito de gestão de crise com as suas principais características e estruturas; analisa a importância da inovação no setor agrícola; oferece uma visão geral do setor; apresenta o impacto da pandemia neste sector e algumas das estratégias de recuperação; por fim, explora as atitudes dos profissionais do setor agrícola em relação à crise da COVID-19 em dois países – em Portugal e na Rússia. Esta investigação pretende descobrir as diferenças e semelhanças nas soluções de gestão de crise entre os profissionais de agro-negócios de ambos os países, bem como os possíveis abordagens relativamente à minimização dos impactos da crise.

This article proposes a constitutional approach of the role of Government in Economy, and the principle of subsidiarity in the 1993 Peruvian Constitution. The proposal discusses the generally accepted notion of promotion in Public Law, as a reference to establish when Government can develop business activity within the framework of the 1993 Constitution. The discussion adopts the point of view of the Public Law to analyze the principle of subsidiarity of Government when it comes to developing business. ; El artículo propone una interpretación constitucional del rol promotor del Estado y del principio de subsidiariedad en la Constitución de 1993, sobre la base de la noción de fomento, generalmente aceptada por la doctrina, como criterio para establecer cuándo puede el Estado desarrollar actividad empresarial en el marco de la Carta Magna vigente. El análisis se desarrolla desde el punto de vista del derecho público y utiliza para ello el enfoque horizontal1 del principio de subsidiariedad.

The transition to a circular economy (CE) remains an anticipated future with alternative pathways for its fulfillment. Most research on CE is normative about technological approaches and interpretations for production and sustainable development. However, critical reviews of CE help understand that CE's emergence is constrained to current dominant goals. As a set of imagined futures, the visions of CE are produced and shared in discursive practices. We hypothesize that the existence of alternative discourses about CE originates from alignment with or divergence from current dominant goals. Green growth holds the dominant position as a goal in the European discourse about CE. In this study, we present an empirical case of an emerging CE in the region of Trøndelag in Norway. This case uses qualitative data collected through interviews with informants in the public and private sectors (profit and non-profit organizations). The analysis of these interviews involved the use of a discourse coalition framework as a method. We identified three discourse coalitions: 1) Waste as resources: a vision of better product design and waste sorting technologies making recycling more efficient. 2) Sharing economy: a vision of industrial symbiosis, and new business models for local commercial offerings in sharing, reuse, repair of products. 3) Reduction of individual consumption: a vision of individual changes in lifestyle, coupled with local services and skill acquisition/transfer for reuse and repair. The first two operate in alignment with the political goal of green growth. The third one diverges by questioning it and setting focus on individual consumption reduction. We found discursive competition in CE when the focus is on the goal underlying its enactment. From this finding, we raise the question of which kinds of technological implementation and political challenges would come from shifting CE's policy goal to reducing individual consumption. To illustrate an alternative CE that emerges from consumption reduction, we discuss its implications based on the insights from our empirical case. The main contribution of the article is to provide evidence and an example of an emerging aspect that can be integrated more prominently in CE and that requires a stance that is not based on economic growth. ; publishedVersion ; © 2020 The Author(s).

Doutoramento em Economia ; By focusing on the relationship between financial stability and monetary policy for the cases of Chile, Colombia, Japan, Portugal and the UK, this thesis aims to add to the existing literature on the fundamental issue of the relationship between financial stability and monetary policy, a traditional topic that gained importance in the aftermath of the GFC as Central Banks lowered policy rates in an effort to rescue their economies. As the zero-lower bound loomed and the reach of traditional monetary policy narrowed, policy makers realised that alternative frameworks were needed and hence, macroprudential policy measures aimed at targeting the financial system as a whole were introduced. The second chapter looks at the relationship between monetary policy and financial stability, which has gained importance in recent years as Central Bank policy rates neared the zero-lower bound. We use an SVAR model to study the impact of monetary policy shocks on three proxies for financial stability as well as a proxy for economic growth. Monetary policy is represented by policy rates for the EMEs and shadow rates for the AEs in our chapter. Our main results show that monetary policy may be used to correct asset mispricing, to control fluctuations in the real business cycle and also to tame credit cycles in the majority of cases. Our results also show that for the majority of cases, in line with theory, local currencies appreciate following a positive monetary policy shock. Monetary policy intervention may indeed be successful in contributing to or achieving financial stability. However, the results show that monetary policy may not have the ability to maintain or re-establish financial stability in all cases. Alternative policy choices such as macroprudential policy tool frameworks which are aimed at targeting the financial system as a whole may be implemented as a means of fortifying the economy. The third chapter looks at the institutional setting of the countries in question, the independence of the Central Bank, the political environment and the impact of these factors on financial Abstract stability. I substantiate the literature review discussion with a brief empirical analysis of the effect of Central Bank Independence on credit growth using an existing database created by Romelli (2018). The empirical results show that there is a positive relationship between credit growth and the level of Central Bank Independence (CBI) due to the positive and statistically significant coefficient on the interaction term between growth in domestic credit to the private sector and the level of CBI. When considering domestic credit by deposit money banks and other financial institutions, the interaction term is positive and statistically significant for the case of the UK for the third regression equation. A number of robustness checks show that the coefficient is positive and statistically significant for a number of cases when implementing a variety of estimation methods. Fluctuations in credit growth are larger for higher levels of CBI and hence, in periods of financial instability or ultimately financial crises, CBI would be reined back in an effort to re-establish financial stability. Based on the empirical results, and in an effort to slow down surging credit supply and to maintain financial stability, policy makers and governmental authorities should attempt to decrease the level of CBI when the economy shows signs of overheating and credit supply continues to increase. The fourth chapter looks at the interaction between macroprudential policy and financial stability. The unexpected interconnectedness of the global economy and the economic blight that occurred as a result of this, recapitulated the need to implement an alternative policy framework aimed at targeting the financial system as a whole and hence, targeting the maintenance of financial stability. In this chapter, an index of domestic macroprudential policy tools is constructed and the effectiveness of these tools in controlling credit growth, managing GDP growth and stabilising inflation growth is studied using a dynamic panel data model for the period between 2000 and 2017. The empirical analysis includes two panels namely an EU panel of 27 countries and a Latin American panel of 7 countries, the chapter also looks at a case study of Japan, Portugal and the UK. Our main results find that a tighter macroprudential policy tool stance leads to a decrease in both credit growth and GDP growth while, a tighter macroprudential policy tool stance results in higher inflation in the majority of cases. Further, we find that capital openness plays a more important role in the case of Latin America, this may be due to the region's dependence on foreign capital flows and exchange rate movements. Lastly, we find that, in times of higher perceived market volatility, GDP growth tends to be higher and inflation growth tends to be lower in the EU. In the other cases, higher levels of perceived market volatility result in higher inflation, higher credit growth and lower GDP Abstract growth. This is in line with expectations as an increase in perceived market volatility is met with an increased flow of assets into safer markets such as the EU. This thesis establishes a relationship between financial stability and monetary policy by studying the response of Chile, Colombia, Japan, Portugal and the UK in the aftermath of the GFC as Central Banks lowered policy rates in an effort to rescue their economies. In short, the results of the work conducted in this thesis may be summarised as follows. Our results show that monetary policy contributes to the achievement of financial stability. Still, monetary policy alone is not sufficient and should be reinforced by less traditional policy choices such as macroprudential policy tools. Secondly, we find that the level of CBI should be reined in in times of surging credit supply in an effort to maintain financial stability. Finally, we conclude that macroprudential policy tools play an important role in the achievement of financial stability. These tools should complement traditional monetary policy frameworks and should be adapted for each region. ; info:eu-repo/semantics/publishedVersion

The article discloses the foundations of the stock market development and understanding the essence of the stock market infrastructure based on the study of existing approaches to state regulation of the provision of financial services, in particular in the stock market. A key component of the stock market infrastructure is the implementation of exchange trading in securities, which is determined by the volume and number of securities on stock exchanges. The analysis of the conditions for the development and growth of the total volume of exchange trading in securities in the framework of the analysis of the dynamics of trading on the stock market of Ukraine in 2014–2020, which is determined by the desire to increase the capitalization of market participants. The conditions for the development of the stock market infrastructure and measures of government influence on the participants in financial relations, which will include sufficient institutional, organizational, technical, financial support for their interaction in the market, are indicated. It is noted that the key in the development of the stock market is the mechanism of state regulation and self-regulation. The directions of state regulation in the development of the stock market have been determined, which implies the implementation of measures to improve the activity of capital markets in order to attract additional investmentresources to the country's economy and reduce the barriers to access to the stock market. In this context, government regulation should help to strengthen the institutional foundations of the stock market with the improvement of the processes of issuing government debt securities, as one of the most effective tools for attracting monetary resources to the country's economy at the present stage. However, this can be achieved by developing a comprehensive strategy for managing government debt securities and studying the possibility of their targeted use for those industries or projectsthat ensure economic development and create prerequisites for expandedreproduction. ; В статье раскрыты основы развития фондового рынка и понимание сущности инфраструктура фондового рынка на основе исследования существующих подходов к государственному регулированию деятельности по предоставлению финансовых услуг, в частности на фондовом рынке.

This work assesses the capacity of a microalgae-based system to remove three highly to medium polar pesticides typically found in freshwater: acetamiprid, bentazone, and propanil. Degradation of the pesticides was firstly studied individually at batch lab-scale reactors and abiotic and heated-killed controls were employed to clarify their removal pathways. At lab-scale, propanil and acetamiprid were completely removed after 7 days whereas bentazone was not removed. Four and two transformation products (TPs) were generated in the biodegradation process for acetamiprid and propanil, respectively. Then, the simultaneous removal of the pesticides was assessed in an outdoor pilot photobioreactor, operated with a hydraulic residence time of 8 days. During the steady-state, high removal efficiencies were observed for propanil (99%) and acetamiprid (71%). The results from batch experiments suggest that removal is mainly caused by algal-mediated biodegradation. Acetamiprid TPs raised throughout the operational time in the photobioreactor, while no propanil TP was detected at the pilot-scale. This suggests complete mineralization of propanil or residual formation of its TPs at concentrations below the analytical method detection limit. Aiming at biomass valorization, diverse microalgae harvesting methods were investigated for biomass concentration, and the effect of residual pesticides on the biogas yield was determined by biochemical methane potential tests. Anaerobic digestion was not inhibited by the pesticides as verified by the digestion performance. The results highlight the potential of microalgae-based systems to couple nutrient removal, biomass production, micropollutant biodegradation, and biofuel production. ; This work has been supported by the Spanish Ministry of Economy and Competitiveness State Research Agency (CTM2016-75587-C2-1-R and CTM2016-75587-C2-2-R) and co-financed by the European Union through the European Regional Development Fund (ERDF) and the Horizon 2020 research and innovation WATERPROTECT project (727450).

This environmental problem may be solved by phytoremediation, which is an effective strategy to manage and remediate contaminated areas. During this remediation process, the establishment of plant communities may improve soil fungal community structure and, in particular, may favour mycorrhizal symbiotic associations. As a consequence, afforestation of degraded lands will have different outcomes on fungal diversity and functionality, which will depend on the selected tree and shrub species. We analysed soil fungal diversity and functional guilds by high-throughput sequencing of environmental DNA in a trace element contaminated area, part of a large scale phytoremediation project running for 20 years. We selected five habitats for comparison purposes: three under the canopy of selected tree species (wild olive, white poplar and stone pine), adjacent treeless areas (grassland) and non-remediated areas (bare soil). Soil fungal diversity and richness seemed to be enhanced by phytoremediation. White poplar soil had the highest diversity and richness compared to wild olive and stone pine. Fungal communities were especially different between stone pine, with soils rich in organic C and high C:N ratio, and grassland soils. We identified 9,428 fungal OTUs from which 1,283 were assigned to a unique functional guild; the most abundant belonging to saprotrophic, plant pathogenic and ectomycorrhizal functional guilds. Ectomycorrhizal fungi were more abundant in soils under ectomycorrhizal host trees. Saprotrophs were abundant in grassland and wild olive soils, while plant pathogens were abundant in non-remediated soils. The remediation of soils (clean-up and amendment addition) allowed the natural establishment of grassland habitats throughout the study area, increasing fungal diversity, richness, taxonomy and functionality, when compared to non-remediated soils. Tree afforestation allowed the establishment of a forest type community bringing a further recruitment of fungal taxa, mainly the ectomycorrhizal fungal guild. Afforestation with different tree species showed species-specific effects on soil N, organic C, Ca and C:N ratio which led to increased spatial heterogeneity in areas with potential to recruit a wider diversity of fungi. ; This work was supported by European Union Seventh Framework Programme (FP7/2007–2013) [grant number 603498 - RECARE], and Spanish Ministry of Science, Innovation and Universities [grants number CGL2014-52858-R – RESTECO and CGL2017-82254-R – INTARSU].

This PhD thesis seeks to contribute towards closing a research gap in the knowledge about the African Union Mission in Somalia (AMISOM) as an African Union (AU) and United Nations (UN) authorised peace enforcement operation. In so doing, the study covers the period 2007-2017 and attempts to fulfil three broad objectives. Firstly, it examines the implementation of AMISOM mandate amidst foreign interventions and their underlying implications for the strategic AU-UN partnership. Secondly, the thesis attempts to examine any significant changes towards the implementation of the mandate by assessing the evolution of AMISOM's decade-long presence in Somalia. The analysis focuses on whether AMISOM has morphed into an exercise in self-interest or still pursuing the shared strategic objectives for which it was established. Thirdly, the study confronts the theoretical idea imposed by Western ideologies to export liberal democracy through peacekeeping operations, especially as it relates to regional peace operations. In a sense, it contrasts between liberalism and realism vis-à-vis peacekeeping operations in order to account for the case of AMISOM given the involvement of frontline states whose realist strategy in Somalia has presented a major dilemma. Given the latitude, the study adopts an interdisciplinary and mixed methodology approach in its analysis of foreign interventions and the pursuit of illicit commercial interests in a conflict economy milieu marked by attempts to counter al-Shabaab in Somalia. As a qualitative research, the study relies on primary and secondary data sources including relevant articles and journals, although aspects of quantitative method have also been used where appropriate. ; Esta tese de doutoramento visa contribuir para o preenchimento de uma lacuna de pesquisa no conhecimento sobre a Missão da União Africana na Somália (AMISOM), como uma operação de imposição da paz autorizada pela União Africana (UA) e endossada pelas Nações Unidas (ONU). O âmbito do estudo abrange o período 2007- 2017 e ambiciona cumprir três objetivos principais. Em primeiro lugar, examina a implementação do mandato da AMISOM no meio de intervenções estrangeiras e as suas implicações subjacentes para a parceria estratégica UA-ONU. Em segundo lugar, a tese tenta examinar quaisquer mudanças significativas em relação à implementação do mandato, avaliando a evolução da AMISOM após uma década de presença na Somália. A análise concentra-se em determinar se a AMISOM se transformou num exercício em interesse próprio ou se ainda persegue os objetivos estratégicos comuns para os quais foi estabelecida. Em terceiro lugar, o estudo confronta a ideia teórica imposta pelas ideologias ocidentais para exportar a democracia liberal por meio de operações de manutenção da paz, especialmente no que se refere as operações de paz regionais. Em certo sentido, contrasta entre liberalismo e realismo face às operações de manutenção da paz com vista a contextualizar o caso da AMISOM, dado o envolvimento dos Estados da linha da frente, cuja estratégia realista na Somália apresentou um grande dilema. Dada a latitude, o estudo adopta uma abordagem metodológica interdisciplinar e mista, na análise de intervenções estrangeiras e a prossecução de interesses comerciais ilícitos, num ambiente de economia de guerra marcado por tentativas de conter o "al-Shabaab" na Somália. Tratando-se de uma pesquisa qualitativa, o estudo baseia-se principalmente em fontes primárias e secundárias, incluindo artigos e periódicos relevantes, embora alguns aspectos do método quantitativo tenham sido também aplicados.
