The aim of this work is to present and investigate a model that departs from three considerations. First, fiscal policy and debt sustainability are two sides of the same coin: the former is the policy instrument that government manages in the present time to achieve its social objectives, whereas, the latter is the repercussion of the former in the long run. Second, fiscal policy has a direct impact on industries capital accumulation because it affects the available income and, therefore, their savings; such an impact can be evaluated through the intertemporal optimization of industries saving decisions. Finally, fiscal policy has to be characterized on both the revenue and the spending side: revenues are determined through a unique tax rate, while spending is represented as an industry-based subsidy with a fixed fraction, Φ, that must be re-invested in capital. The production function in each industry is assumed AK and investment is subjected to quadratic adjustment costs. The consequences of assuming a convex adjustment cost function are twofold: the model does not display growth in the long run and the invested capital due to the public incentivization program hyper-crowds out private saving, consequently the optimal Φ is 0. Another advantage, due to the simplicity of the framework, is that the notion of debt sustainability, contrary to the majority of literature on fiscal policy sustainability, is defined unambiguously therefore it is always possible to determine whether a certain public debt can be sustained. In section 4, the model is solved as a Nash bargaining problem by assuming an explicit welfare function and it is found that the optimal government size results undetermined whenever the optimal Φ is 0. However, in the conclusions, it is proposed a way to modify slightly the model in order to overcome the problem of the hyper-crowding-out and letting the designed public program of capital incentivization work effectively.

U političkome trenutku kada se Europska unija percipira kao specifična politička organizacija kompleksnoga multirazinskog sustava vlasti koji prevladava nacionalne i manjinske probleme, pojavile su se tendencije unutarnjega identitetskog i političkog komešanja kod pojedinih država članica. Španjolska predstavlja izuzetan primjer recentne političke nestabilnosti proizvedene uslijed najava referendumskih izjašnjavanja građana Katalonije o potencijalnoj neovisnosti. Ekonomska kriza koja je pogodila Španjolsku zasigurno je katalizator spomenutih tendencija, ali nipošto jedini ili odlučujući faktor u političkome zahtjevu za neovisnošću ili barem povećanom autonomijom unutar Španjolske. Potonja ima dugu povijest sukobljavanja centralističkih i regionalno-federalističkih tradicija, a njezina identitetska kompleksnost nipošto ne odgovara centralističkomu sustavu vlasti i političke teritorijalizacije. Stoga su izazovnost tematike španjolskoga regionalnog modela, njegova problematika i zahtjevi za revidiranjem suviše važna tematika koja zahtijeva pažljivo proučavanje mnoštva aspekata koje ovaj model podrazumijeva. Ovaj rad nema namjeru sveobuhvatne analize španjolskoga regionalnog ustrojstva, već kratak presjek najznačajnijih elemenata koji su reaktualizirani u novijim događajima te njihovo smještanje u odgovarajuće teorijske modele radi lakšega razumijevanja i interpretacije. ; In today's political situation when the European Union is percevied as a specific political organization with a complex multilevel system of authority which overcomes national and minority problems, certain identity and political restlesness started to emerge in some member states. Spain is an excellent example of recent political instability created due to the announcement of the citizens referendum on potential self-determination in Catalonia. Economic crisis which has affected Spain is definitely a catalyst of the mentioned tendencies, but by no means the only and decisive factor in the political claims for independence or at least greater autonomy within Spain. The latter has a long history of conflict between centralist and regional-federal traditions, and the complexity of its identity in no way corresponds to the centralized system of government and political territorialization. Therefore, the challenging themes of Spanish regional model, its problems and requirements for its revisionism are extremely important issues which require careful study from multiple aspects that such model implies. This paper is not a comprehensive analysis of Spanish regional organization, but a brief overview of its most significant elements reaffirmed in the most recent events as well as their positioning within appropriate theorethical models for easier understanding and interpretation.

Questo saggio mira a presentare un modello in divenire volto ad analizzare gli spazi pubblici urbani (UPS), fondato su quattro dimensioni localmente situate –socioeconomica, socioculturale, socio-ambientale e politico-amministrativa – e una dimensione esterna, strutturale. In quanto modello relazionale, si concentra sul modo in cui le istituzioni capitaliste/statali e le loro rappresentazioni dello spazio plasmano luoghi e possibilità disuguali e sul modo in cui i cittadini percepiscono, vivono e si appropriano di questi luoghi, conformandosi in misura maggiore o minore allo spazio sociale della città. Un caso studio incentrato sulle persone di Rio de Janeiro che hanno fatto della strada un mezzo di produzione/riproduzione esaminerà il valore euristico del modello, rivelando come gli utenti si sentono nello spazio pubblico urbano, lo pensano e come reagiscono allo spazio "astratto". This essay aims at presenting a model with four non-exhaustive local content dimensions – socioeconomic, sociocultural, socio-environmental, and political-administrative – with an external dimension as a base to analyze urban public spaces (UPS). As a relational model it focus on how capitalist/state institutions and their representations of space conform unequal places and possibilities and how citizens perceive, live and appropriate these places, conforming to greater or lesser degree the city social space. A case study focusing on those who depend on the streets as means of production/reproduction in Rio de Janeiro examines the heuristic value of the model, revealing how users feel and think about UPS and how they react to the abstract space

A reflection on the possibility of drawing up a filing plan model that all Italian public administrations can adopt, with suitable modifications, for managing records of the current archive. The task assigned to the Working Group, by the Agency for Digital Italy - AGID, for developing a model of filing plan scheme has been analysed with the aim to identify both the strong points of a shared project and the related difficulties and problems found.The functional analysis of different types of government has identified a considerable overlap of the generic parts, referring to the general and instrumental functions, assuming a real feasibility of a shared filing plan model in a large scale. It has also highlighted the difficulty in maintaining the same consistency in translating specific and particular functions of other types of public administrations within the same filing plan model. ; Una riflessione sulla possibilità di predisporre un modello di Titolario di classificazione che tutte le pubbliche amministrazioni italiane possano adottare, con gli opportuni adattamenti, per la classificazione dell'archivio corrente. Il lavoro svolto Gruppo di Lavoro, promosso dall'Agenzia per l'Italia Digitale – AGID, incaricato di elaborare lo schema tipo di Titolario è analizzato con l'intento di individuare, da una parte, i punti di forza di un progetto condiviso e dall'altra, le difficoltà e le criticità riscontrate. L'analisi funzionale di diverse tipologie di pubbliche amministrazioni ha individuato una cospicua sovrapponibilità delle parti generiche, relative alle funzioni generali e strumentali, ipotizzando una reale fattibilità di un modello di Titolario condivisibile a larga scala; ha nel contempo, tuttavia, evidenziato la difficoltà di mantenere la medesima coerenza progettuale nel tradurre nello stesso modello di Titolario le funzioni specifiche e peculiari delle diverse tipologie di pubbliche amministrazioni.

This paper outlines the EU regulatory framework and analyses current practice in four European countries in respect of public procurement and tendering of ferry services. Tender management for major ferry services resides with national government agencies, while tenders for smaller volume regional and/or inter-isles services are generally managed by local authorities and/or regional transport authorities. Operator selection criteria increasingly emphasises service quality aspects, and environmental impacts, as well as price (i.e. amount of subsidy required). There is a continued trend towards privately-owned operators providing and investing in essential ferry services, with an increasing role played by larger international integrated transport organisations. For transport authorities, ferry service procurement involves a continuous evolutionary process of specifying, offering, selecting, monitoring and reviewing services supplied. Based on the information collected and analysed, the authors have developed a 'tender route map' which explains the different stages and key issues concerning public procurement of ferry services.

With the proliferation of social media, textual emotion analysis is becoming increasingly important. Sentiment Analysis and Emotion Detection can be useful to track several applications. They can be used, for instance, in Customer Relationship Management to track sentiments towards companies and their services, or in Government Intelligence, to collect people's emotions and points of views about government decisions. It is clear that tracking reputation and opinions without appropriate text mining tools is simple infeasible. Most of these tools are based on sentiment and emotion lexicons, in which lemmas are associated with the sentiment and/or emotions they evoke. However, almost all languages but English lack high-coverage inventories of this sort. This thesis presents several sentiment analysis tasks to illustrate challenges and opportunities in this research area. We review different state-of-the-art methods for sentiment analysis and emotion detection and describe how we modeled a framework to build emotive resources, that can be effectively exploited for text affective computing. One of the main outcome of the work presented in this thesis is ItEM, which is a high-coverage Italian EMotive lexicon created by exploiting distributional methods.It has been built with a three stage process including the collection of a set of highly emotive words, their distributional expansion and the validation of the system. Since corpus-based methods reflect the type of the corpus from which they are build, in order to create a reliable lexicon we collected a new Italian corpus, namely FB-NEWS15. This collection has been created by crawling the Facebook pages of the most important Italian newspapers, which typically include a small number of posts written by the journalists and a very high number of comments inspired by long discussions among readers about such news. Finally, we describe some experiments on the sentiment polarity classification of tweets. We started from a system based on supervised learning that was originally developed for the Evalita 2014 SENTIment POLarity Classification task (Basile et al., 2014) and subsequently explored the possibility to enrich this system by exploiting lexical emotive features derived from social media texts.

Public good provision has always been a central role of government, but it is also an important element in political competition. The recent financial difficulties of public authorities have undermined their capacity to invest in public goods, requiring politicians to search for new ways to finance those investments. A solution widely adopted is the Public-Private Partnership, an instrument designed to provide more valuable public goods thanks to efficiency gains coming from bundling building and operating phases in a single contract, but that has often resulted in resounding failures. The most common explanation for this lack of results is that PPP are often adopted not for efficiency purposes but to avoid financial constraints. We build a model to analyze the incentives for politicians to use PPP for pork barrel politics in presence of a binding budget constraint, when they have a better ability to look forward than their voters, and are limited in their possibility to stay in charge. We then release the assumption of homogeneous income among voters, and analyze how this modifies politician's incentives to pander.

I provide a full characterization of the quality choice in duopolies with vertical differentiation, without assuming ex-ante if the market is fully covered or not. This will allow to show that covered or uncovered market configurations are endogenous outcomes of firms' strategic interaction. To this purpose, I assume that firms are characterized by quadratic fixed costs of quality improvements and check whether pure-strategy subgame perfect equilibria with a corner solution always exist. Finally, my results are compared to the quality choice that maximizes the total surplus of the economy. I show that the welfare-maximizing choice of qualities does not have to be found in the same market configuration of the corresponding market equilibrium.

Osnovni je cilj ovog rada utvrditi potencijalno učinkovit smjer razvoja politike razvojne suradnje Republike Hrvatske kao države članice Europske unije i države donatora. Radom se predlaže praćenje globalnih i europskih trendova razvoja te politike primjenom modela delegirane razvojne suradnje kojim je moguće ostvarivati vlastite ciljeve i stjecati koristi ne upotrebljavajući isključivo vlastita nacionalna sredstva i resurse, nego podjelom donatorskih aktivnosti, uz ekspertize i resurse svih uključenih donatora te istodobno ostvarivanje učinkovitih rezultata. Imajući u vidu ograničene financijske resurse za provedbu te politike te preuzete obveze primarno spram Europske unije, provedena analiza u radu ukazuje na model delegirane razvojne suradnje kao na moguće strateško opredjeljenje Republike Hrvatske u provedbi predmetne politike u idućem razdoblju. Holistički pristup razvoju te politike, specijalizacija za određena područja djelovanja te integracija s drugim donatorima identificirani su kao predstojeći izazovi za Republiku Hrvatsku, a ujedno i kao preduvjeti primjene modela delegirane razvojne suradnje. ; The main aim of this study is to determine possible strategic guidance for increasing the effectiveness of implementing the development cooperation policy in the Republic of Croatia, bearing in mind its membership of the European Union and the fact that, since 2011, the Republic of Croatia has been officially classified as an international donor. Thus, taking into consideration the limited financial resources available for the implementation of this policy, the analysis in this study proposes a model of delegated cooperation as a possible strategic commitment on the part of the Republic of Croatia in policy implementation in the coming period. The delegated cooperation model should be considered in the context of the Republic of Croatia's meeting its commitments towards the European Union and the global donor community, as well as guidance for alignment with current global donor trends in policy implementation. Furthermore, it should be seen as beneficial in terms of achieving the visibility of the Republic of Croatia as a donor country, its proliferation through comparative advantage, and the withdrawal of European Union funds in order to achieve its own benefits and ultimate fulfillment of global development goals. In order to achieve this, structural changes should be introduced regarding the necessary political commitments and appropriate institutional and procedural reforms. In this respect, the need to introduce changes in the existing political system of the Republic of Croatia should be considered.
