The changing politics of preference formation in international trade negotiations: the European Union in the Doha Round

This research seeks to provide an explanation for variations of “politics” of preference formation in international trade negotiations. Building on the ‘policy determines politics’ argument, I hypothesize the existence of a causal relationship between issue-characteristics and their variations with politics dynamics and their variations. More specifically, this study seeks to integrate into a single analytical framework two dimensions along which variations in the “politics of preference formation” can be organized: configurations of power relationships among the relevant actors in the structures within which they interact as well as the logic and the motivations of the actors involved in the policy making process. To do so, I first construct a four-cell typology of ‘politics of preference formation’ and, then, I proceed by specifying that the type of state-society configurations as well as the type of actors’ motivations in the “politics of preference formation” depend, respectively, on the degree to which a policy issue is perceived as politically salient and on the extent to which the distributional implications of such an issue can be calculated by the relevant stakeholders in the policy making process. The empirical yardstick against which the validity of the theoretical argument proposed is tested is drawn from evidence concerning the European Union’s negotiating strategy in four negotiating areas in the context of the so-called WTO’s Doha Development Round of multilateral trade negotiations: agriculture, competition, environment and technical assistance and capacity building.

In nome della comunità. Analisi dei testi della sicurezza e del terrorismo

The focus of this dissertation is the relationship between the necessity for protection and the construction of cultural identities. In particular, by cultural identities I mean the representation and construction of communities: national communities, religious communities or local communities. By protection I mean the need for individuals and groups to be reassured about dangers and risks. From an anthropological point of view, the relationship between the need for protection and the formation and construction of collective identities is driven by the defensive function of culture. This was recognized explicitly by Claude Lévi-Strauss and Jurij Lotman. To explore the “protective hypothesis,” it was especially useful to compare the immunitarian paradigm, proposed by Roberto Esposito, with a semiotic approach to the problem. According to Esposito, immunity traces borders, dividing Community from what should be kept outside: the enemies, dangers and chaos, and, in general, whatever is perceived to be a threat to collective and individual life. I recognized two dimensions in the concept of immunity. The first is the logic dimension: every element of a system makes sense because of the network of differential relations in which it is inscribed; the second dimension is the social praxis of division and definition of who. We are (or what is inside the border), and who They are (or what is, and must be kept, outside the border). I tested my hypothesis by analyzing two subject areas in particular: first, the security practices in London after 9/11 and 7/7; and, second, the Spiritual Guide of 9/11 suicide bombers. In both cases, one observes the construction of two entities: We and They. The difference between the two cases is their “model of the world”: in the London case, one finds the political paradigms of security as Sovereignty, Governamentality and Biopolitics. In the Spiritual Guide, one observes a religious model of the Community of God confronting the Community of Evil. From a semiotic point view, the problem is the origin of respective values, the origin of respective moral universes, and the construction of authority. In both cases, I found that emotional dynamics are crucial in the process of forming collective identities and in the process of motivating the involved subjects: specifically, the role of fear and terror is the primary factor, and represents the principal focus of my research.

Educazione alla cittadinanza per cittadini immigrati adulti. Il contributo della formazione linguistico-giuridica all'acquisizione di competenze di cittadinanza in lingua seconda

The research examines which cultural and linguistic instruments can be offered to provide adult migrants with formative access to citizenship competences. Starting from the questions: How can individuals of all community groups present in a nation-state acquire high standards of linguistic, sociolinguistic and discourse competences in order to be fully integrated, that is to participate and be included in social activities in the public domain such as work and institutional environments? How are these competencies developed in an educational context? How do adult migrants behave linguistically in this context, according to their needs and motivations? The research hypothesis aimed at outlining a formative project of citizenship education targeted at adult foreign citizens, where a central role is assigned both to law education and linguistic education. Acoordingly, as the study considered if the introduction of a law programme in a second language course could be conceived as an opportunity to further the access to active citizenship and social participation, a corpus of audiodata was collected in law classes of an Italian adult professional course attended by a 50% of foreign students. The observation was conducted on teacher and learner talk and learner participation in classroom interaction when curriculum legal topics were introduced and discussed. In the classroom law discourse two dimensions were analyzed: the legal knowledge construction and the participants’ interpersonal and identity construction. From the analysis, the understanding is that drawn that law classes seem to represent an educational setting where foreign citizens have an opportunity to learn and practise citizenship. The social and pragmatic approach to legal contents plays a relevant role, in a subject which, in non-academic contexts, loses its technical specificity and refers to law as a product of social representation. In the observed educational environment, where students are adults who bring into the classroom multiple personal and social identities, legal topics have the advantage of increasing adult migrants’ motivation to ‘go back to school’ as they are likely to give hints, if not provide solutions, to problems relating to participation in socio-institutional activities. At the same time, these contents offer an ideal context where individuals can acquire high discourse competences and citizenship skills, such as agency and critical reflection. Besides, the analysis reveals that providing adult learners with materials that focus on rights, politics and the law, i.e. with materials which stimulate discussion on concerns affecting their daily lives, is welcomed by learners themselves, who might appreciate the integration of these same topics in a second language course.

Reputation, VC funding, and innovation: Evidence from the UK Micro and Nanotechnology sector

Startups’ contributions on economic growth have been widely realized. However, the funding gap is often a problem limiting startups’ development. To some extent, VC can be a means to solve this problem. VC is one of the optimal financial intermediaries for startups. Two streams of VC studies are focused in this dissertation: the criteria used by venture capitalists to evaluate startups and the effect of VC on innovation. First, although many criteria have been analyzed, the empirical assessment of the effect of startup reputation on VC funding has not been investigated. However, reputation is usually positively related with firm performance, which may affect VC funding. By analyzing reputation from the generalized visibility dimension and the generalized favorability dimension using a sample of 200 startups founded from 1995 operating in the UK MNT sector, we show that both the two dimensions of reputation have positive influence on the likelihood of receiving VC funding. We also find that management team heterogeneity positively influence the likelihood of receiving VC funding. Second, studies investigating the effect of venture capital on innovation have frequently resorted to patent data. However, innovation is a process leading from invention to successful commercialization, and while patents capture the upstream side of innovative performance, they poorly describe its downstream one. By reflecting the introduction of new products or services trademarks can complete the picture, but empirical studies on trademarking in startups are rare. Analyzing a sample of 192 startups founded from 1996 operating in the UK MNT sector, we find that VC funding has positive effect on the propensity to register trademarks, as well as on the number and breadth of trademarks.

The role of proactive coping strategies and perceived health status for Social well-being and life-project in old age.

The latter part of the 20th century was a period characterized by a fundamental demographic transition of western society. This substantial and structural demographic change proposes several challenges to contemporary society and fosters the emergence of new issues and challenges. Among these, none is more crucial than the comprehension of the mechanisms and the processes that lead people to positive aging. Rowe and Kahn’s model of successful aging highlights the interplay between social engagement with life, health, and functioning for a positive aging experience. Other systemic models of successful aging (Kahana et al., 1996; 2003; Stevernik et al., 2006) emphasize the role of internal and external resources for attaining positive aging. Among these, the proactive coping strategies are indicated as important active strategies for avoiding the depletion of resources, counterbalancing the declines and maintaining social and civic involvement. The study has analyzed the role of proactive coping strategies for two facets of positive aging, the experience of a high social well-being and the presence of personal projects in fundamental life domains. As expected, the proactive coping strategies, referred to as the active management of the environment, the accumulation of resources and the actualization of human potentials are confirmed as positive predictors of high level of social well-being and of many personal projects focused on family, culture, leisure time, civic and social participation. Perceived health status give a significant contribution only to the possession of many personal projects. Gender and level of school education give also a significant contribution to these two dimensions of positive aging, highlighting how positive aging is rooted not only in the possession of personal resources, but also in historical models of education and in positive longitudinal chains related to early development.

El principio de neutralidad interna en el IVA

La tesis estudia el principio de neutralidad en su vertiente interna y su aplicación efectiva en el IVA. Se centra en los principales aspectos de la configuración jurídica del impuesto: derecho de deducción, exenciones y tipos reducidos. Se realiza en primer lugar una aproximación teórica al principio desde un punto de vista jurídico y también económico. Una vez construido el principio se acomete una comparación de las distintas clases de impuestos indirectos que pueden establecerse y se analiza su cumplimiento del principio de neutralidad fiscal. El énfasis es mayor en los impuestos en cascada, impuestos monofásicos minoristas y en el IVA. El objetivo de la tesis es, por tanto, concretar el contenido del principio, desarrollar sus implicaciones económicas principales y analizar el grado de cumplimiento real de la Directiva IVA. Desde el punto de vista del derecho de deducción y de las exenciones el estudio se apoya en el análisis de la jurisprudencia del Tribunal de Justicia de la Unión Europea, donde se profundizará en cuestiones como la utilización de bienes de uso mixto, la consideración de costes como directos o generales y las formas de ejercicio del exceso de deducción (devolución y compensación). Además, la tesis muestra las principales excepciones al principio de neutralidad establecidas en la Directiva IVA: prohibiciones al derecho de deducción, exenciones y tipos reducidos. En esta parte también se apoyará el estudio en la jurisprudencia del TJUE, que ha construido en gran medida los criterios de interpretación de estas excepciones. En conclusión, el objetivo de la tesis es medir si la directiva IVA cumple con el principio de neutralidad fiscal, para lo que deberá haberse especificado primero su significado concreto y se habrá debido diferenciar entre sus dos dimensiones: interna y externa.

Assessment and optimization of chemical industrial processes from a life cycle perspective

During the PhD program in chemistry, curriculum in environmental chemistry, at the University of Bologna the sustainability of industry was investigated through the application of the LCA methodology. The efforts were focused on the chemical sector in order to investigate reactions dealing with the Green Chemistry and Green Engineering principles, evaluating their sustainability in comparison with traditional pathways by a life cycle perspective. The environmental benefits associated with a reduction in the synthesis steps and the use of renewable feedstock were assessed through a holistic approach selecting two case studies with high relevance from an industrial point of view: the synthesis of acrylonitrile and the production of acrolein. The current approach wants to represent a standardized application of LCA methodology to the chemical sector, which could be extended to several case studies, and also an improvement of the current databases, since the lack of data to fill the inventories of the chemical productions represent a huge limitation, difficult to overcome and that can affects negatively the results of the studies. Results emerged from the analyses confirms that the sustainability in the chemical sector should be evaluated from a cradle-to-gate approach, considering all the stages and flows involved in each pathways in order to avoid shifting the environmental burdens from a steps to another. Moreover, if possible, LCA should be supported by other tools able to investigate the other two dimensions of sustainability represented by the social and economic issues.

Ragnar Östberg. Genius loci e memorie urbane. Stockholms Stadshuset-Nämndhuset e villa Geber

La ricerca si propone di analizzare una di quelle stagioni architettoniche controverse e lontane dalle internazionali strade maestre del nascente Neues Bauen: il romanticismo-nazionale svedese riletto attraverso l’esperienza del suo massimo esponente, Ragnar Östberg (1866-1945). L’obiettivo della tesi non è solamente quello di una revisione della critica storiografica, facendo così luce su una di quelle personalità considerate marginali, quanto quello di ricavare dalla lettura comparata di due tra i suoi progetti, fino ad ora mai indagati, quegli elementi che fanno dell’architettura un “fatto urbano” in cui la collettività può riconoscersi e parallelamente un fatto di rappresentazione della stessa. L’arcipelago di Stoccolma e quel processo di “renovatio urbis” a cui fu sottoposta proprio agli albori del XX secolo furono gli scenari in cui presero vita i due progetti: il complesso formato dallo Stockholms Stadshuset e la vicina parte mai realizzata del Nämndhuset, e villa Geber. Condensano due dimensioni che la città immersa nel paesaggio contiene: la natura urbana dell’edificio municipale e quella domestica della villa urbana isolata. La ricerca intesse un itinerario di disvelamento attraverso una matrice duale di lettura: “genius loci” e memorie urbane. I capitoli cercano di dimostrare come i due casi-studio siano espressione di quella pendolarità di ricerca tra lo spirito del luogo e le rimembranze delle forme urbane della tradizione. Questa analisi ci conduce in un viaggio alla ricerca dell’atlante delle “memorie urbane”, raccolte nei viaggi e nella formazione, comprendendo così il mondo analogico di riferimenti culturali con altre architetture europee della tradizione. I due progetti sorgono in opposte aree di espansione di Stoccolma e, pur nella loro diversità di scala, sono chiara espressione di appropriatezza al luogo e di strutture formali analoghe. Stockholm Stadshuset-Nämndhuset e villa Geber esprimono il metodo di Östberg, dove i riferimenti raccolti dall’imagination passive sono tramutati ed assemblati grazie alla imagination active.

Fundamental Dimensions of Social Judgment: Sociability and Morality as Distinct Characteristics of Social Warmth

The present dissertation focuses on the two basic dimensions of social judgment, i.e., warmth and competence. Previous research has shown that warmth and competence emerge as fundamental dimensions both at the interpersonal level and at the group level. Moreover, warmth judgments appear to be primary, reflecting the importance of first assessing others’ intentions before determining the other’s ability to carry out those intentions. Finally, it has been shown that warmth and competence judgments are predicted by perceived economic competition and status, respectively (for a review, see Cuddy, Fiske, & Glick, 2008). Building on this evidence, the present work intends to further explore the role of warmth and competence in social judgment, adopting a finer-grained level of analysis. Specifically, we consider warmth to be a dimension of evaluation that encompasses two distinct characteristics (i.e., sociability and morality) rather than as an undifferentiated dimension (see Leach, Ellemers, & Barreto, 2007). In a similar vein, both economic competition and symbolic competition are taken into account (see Stephan, Ybarra, & Morrison, 2009). In order to highlight the relevance of our empirical research, the first chapter reviews the literature in social psychology that has studied the warmth and competence dimensions. In the second chapter, across two studies, we examine the role of realistic and symbolic threats (akin economic and symbolic competition, respectively) in predicting the perception of sociability and morality of social groups. In study 1, we measure perceived realistic threat, symbolic threat, sociability, and morality with respect to 8 social groups. In study 2, we manipulate the level and type of threat of a fictitious group and measure perceived sociability and morality. The findings show that realistic threat and symbolic threat are differentially related to the sociability and morality components of warmth. Specifically, whereas realistic threat seems to be a stronger predictor of sociability than symbolic threat, symbolic threat emerges as better predictor of morality than realistic threat. Thus, extending prior research, we show that the types of threat are linked to different warmth stereotypes. In the third and the fourth chapter, we examine whether the sociability and morality components of warmth play distinct roles at different stages of group impression formation. More specifically, the third chapter focuses on the information-gathering process. Two studies experimentally investigate which traits are mostly selected when forming impressions about either ingroup or outgroup members. The results clearly show that perceivers are more interested in obtaining information about morality than about sociability when asked to form a global impression about others. The fourth chapter considers more properly the formulation of an evaluative impression. Thus, in the first study participants rate real groups on sociability, morality, and competence. In the second study, participants read an immigration scenario depicting an unfamiliar social group in terms of high (vs. low) morality, sociability, and competence. In both studies, participants are also asked to report their global impression of the group. The results show that global evaluations are better predicted by morality than by sociability and competence trait ascriptions. Taken together the third and the fourth chapters show that the dominance of warmth suggested by previous studies on impression formation might be better explained in terms of a greater effect of one of the two subcomponents (i.e., morality) over the other (i.e., sociability). In the general discussion, we discuss the relevance of our findings for intergroup relation and group perception, as well as for impression formation.

Resonances in the two centers Coulomb system

In this work we investigate the existence of resonances for two-centers Coulomb systems with arbitrary charges in two and three dimensions, defining them in terms of generalized complex eigenvalues of a non-selfadjoint deformation of the two-center Schrödinger operator. After giving a description of the bifurcation of the classical system for positive energies, we construct the resolvent kernel of the operators and we prove that they can be extended analytically to the second Riemann sheet. The resonances are then defined and studied with numerical methods and perturbation theory.

Inferences on earthquake kinematic properties from data inversion: two different approaches

During my PhD, starting from the original formulations proposed by Bertrand et al., 2000 and Emolo & Zollo 2005, I developed inversion methods and applied then at different earthquakes. In particular large efforts have been devoted to the study of the model resolution and to the estimation of the model parameter errors. To study the source kinematic characteristics of the Christchurch earthquake we performed a joint inversion of strong-motion, GPS and InSAR data using a non-linear inversion method. Considering the complexity highlighted by superficial deformation data, we adopted a fault model consisting of two partially overlapping segments, with dimensions 15x11 and 7x7 km2, having different faulting styles. This two-fault model allows to better reconstruct the complex shape of the superficial deformation data. The total seismic moment resulting from the joint inversion is 3.0x1025 dyne.cm (Mw = 6.2) with an average rupture velocity of 2.0 km/s. Errors associated with the kinematic model have been estimated of around 20-30 %. The 2009 Aquila sequence was characterized by an intense aftershocks sequence that lasted several months. In this study we applied an inversion method that assumes as data the apparent Source Time Functions (aSTFs), to a Mw 4.0 aftershock of the Aquila sequence. The estimation of aSTFs was obtained using the deconvolution method proposed by Vallée et al., 2004. The inversion results show a heterogeneous slip distribution, characterized by two main slip patches located NW of the hypocenter, and a variable rupture velocity distribution (mean value of 2.5 km/s), showing a rupture front acceleration in between the two high slip zones. Errors of about 20% characterize the final estimated parameters.
