Aspetti processuali del Regolamento n. 1/2003/Ce

The recent reform in European antitrust enforcement is embodied in Regolation n. 1/2003/ Ce and related Communications. Since 2004 when it came into force, some crytical assessments can already be made. The work starts from some technical analysis of the reform, under a procedural perspective, to assess the proceedings’ real impact on parties’ rights and to criticize its limits. Decentralisation has brought about more complicacies, since community procedural systems are not harmonized, neither in their administrative rules, nor in their civil proceedings, which are all involved in the European antitrust network. Therefore, antitrust proceedings end un as being more jurisdictional in their effects than in their guarentees, which is a flaw to be mended by legislators. National laws shoud be harmonized, community law should be clarified and the system should turn more honestly towards a rationalized jurisdiction-cented mechanism. Otherwise, parties defense rights and the overall efficiency are put into doubt. Italy is a good exemple of how many colmlicacies can outburst from national procedures and national decentralised application. An uncertain pattern of judicial control, together with unclear relationships among the institutions to cooperate in the antitrust network can produce more problems than they aim to solve. As to the private enforcement, Regulation n.1 does not even attempt to give precise regulation to this underdeveloped sector. A continual comparison with U.S. system has brought the Commission to become aware both of the risks and of the advanteges of an increased civil antitrust litigation in fronto of national judges. In order to substain a larger development of this parallel and, presently, difficult way of judicial compensation, it is presently ongoing a consultation among states to find suitable incentives to make private enforcement more appealing and effective. The solution to this lack of private litigation is not to be sought in Regulation n. 1 which calls into action national legislators and proceedures to implement further improvements. As a conclusion, Regulation n. 1 is the outpost of an ambitious community design to create an efficient control mechanism over antitrust violations. It focuses on Commission proceedings, powers and sanctions in order to establish deterrence, then it highlights civil litigation perspectives and it involves directly states into antitrust application. It seems that more could be done to technically shape administrative proceedings in a more jurisdictionally oriented form, then to clarify respective roles and coordination mecanisms in order to prevent difficulties easy to forsee. Some of jurisprudential suggestions have been accepted, but much more is left to be done in the future to improve european antitrust enforcement system.

La costruzione razionale della casa. Scritti e progetti di Giuseppe Pagano

The rational construction of the house. The writings and projects of Giuseppe Pagano Description, themes and research objectives The research aims at analysing the architecture of Giuseppe Pagano, which focuses on the theme of dwelling, through the reading of 3 of his house projects. On the one hand, these projects represent “minor” works not thoroughly known by Pagano’s contemporary critics; on the other they emphasise a particular methodological approach, which serves the author to explore a theme closely linked to his theoretical thought. The house project is a key to Pagano’s research, given its ties to the socio-cultural and political conditions in which the architect was working, so that it becomes a mirror of one of his specific and theoretical path, always in a state of becoming. Pagano understands architecture as a “servant of the human being”, subject to a “utilitarian slavery” since it is a clear, essential and “modest” answer to specific human needs, free from aprioristic aesthetic and formal choices. It is a rational architecture in sensu stricto; it constitutes a perfect synthesis between cause and effect and between function and form. The house needs to accommodate these principles because it is closely intertwined with human needs and intimately linked to a specific place, climatic conditions and technical and economical possibilities. Besides, differently from his public and common masterpieces such as the Palazzo Gualino, the Istituto di Fisica and the Università Commerciale Bocconi, the house projects are representative of a precise project will, which is expressed in a more authentic way, partially freed from political influences and dogmatic preoccupations and, therefore, far from the attempt to research a specific expressive language. I believe that the house project better represents that “ingenuity”, freshness and “sincerity” that Pagano identifies with the minor architecture, thereby revealing a more authentic expression of his understanding of a project. Therefore, the thesis, by tracing the theoretical research of Pagano through the analysis of some of his designed and built works, attempts to identify a specific methodological approach to Pagano’s project, which, developed through time, achieves a certain clarity in the 1930s. In fact, this methodological approach becomes more evident in his last projects, mainly regarding the house and the urban space. These reflect the attempt to respond to the new social needs and, at the same time, they also are an expression of a freer idea of built architecture, closely linked with the place and with the human being who dwells it. The three chosen projects (Villa Colli, La Casa a struttura d’acciaio and Villa Caraccio) make Pagano facing different places, different customers and different economic and technical conditions, which, given the author’s biography, correspond to important historical and political conditions. This is the reason why the projects become apparently distant works, both linguistically and conceptually, to the point that one can define them as ”eclectic”. However, I argue that this eclecticism is actually an added value to the architectural work of Pagano, steaming from the use of a method which, having as a basis the postulate of a rational architecture as essence and logic of building, finds specific variations depending on the multiple variables to be addressed by the project. This is the methodological heritage that Pagano learns from the tradition, especially that of the rural residential architecture, defined by Pagano as a “dictionary of the building logic of man”, as an “a-stylistic background”. For Pagano this traditional architecture is a clear expression of the relationships between a theme and its development, an architectural “fact” that is resolved with purely technical and utilitarian aims and with a spontaneous development far from any aprioristic theoretical principle. Architecture, therefore, cannot be an invention for Pagano and the personal contribution of each architect has to consider his/her close relationship with the specific historical context, place and new building methods. These are basic principles in the methodological approach that drives a great deal of his research and that also permits his thought to be modern. I argue that both ongoing and new collaborations with younger protagonists of the culture and architecture of the period are significant for the development of his methodology. These encounters represent the will to spread his own understanding of the “new architecture” as well as a way of self-renewal by confronting the self with new themes and realities and by learning from his collaborators. Thesis’ outline The thesis is divided in two principal parts, each articulated in four chapters attempting to offer a new reading of the theory and work of Pagano by emphasising the central themes of the research. The first chapter is an introduction to the thesis and to the theme of the rational house, as understood and developed in its typological and technical aspects by Pagano and by other protagonists of the Italian rationalism of the 1930s. Here the attention is on two different aspects defining, according to Pagano, the house project: on the one hand, the typological renewal, aimed at defining a “standard form” as a clear and essential answer to certain needs and variables of the project leading to different formal expressions. On the other, it focuses on the building, understood as a technique to “produce” architecture, where new technologies and new materials are not merely tools but also essential elements of the architectural work. In this way the villa becomes different from the theme of the common house or from that of the minimalist house, by using rules in the choice of material and in the techniques that are every time different depending on the theme under exploration and on the contingency of place. It is also visible the rigorous rationalism that distinguishes the author's appropriation of certain themes of rural architecture. The pages of “Casabella” and the events of the contemporary Triennali form the preliminary material for the writing of this chapter given that they are primary sources to individuate projects and writings produced by Pagano and contemporary architects on this theme. These writings and projects, when compared, reconstruct the evolution of the idea of the rational house and, specifically, of the personal research of Pagano. The second part regards the reading of three of Pagano’s projects of houses as a built verification of his theories. This section constitutes the central part of the thesis since it is aimed at detecting a specific methodological approach showing a theoretical and ideological evolution expressed in the vast edited literature. The three projects that have been chosen explore the theme of the house, looking at various research themes that the author proposes and that find continuity in the affirmation of a specific rationalism, focussed on concepts such as essentiality, utility, functionality and building honesty. These concepts guide the thought and the activities of Pagano, also reflecting a social and cultural period. The projects span from the theme of the villa moderna, Villa Colli, which, inspired by the architecture of North Europe, anticipates a specific rationalism of Pagano based on rigour, simplicity and essentiality, to the theme of the common house, Casa a struttura d’acciaio, la casa del domani, which ponders on the definition of new living spaces and, moreover, on new concepts of standardisation, economical efficiency and new materials responding to the changing needs of the modern society. Finally, the third project returns to the theme of the, Villa Caraccio, revisiting it with new perspectives. These perspectives find in the solution of the open plant, in the openness to nature and landscape and in the revisiting of materials and local building systems that idea of the freed house, which express clearly a new theoretical thought. Methodology It needs to be noted that due to the lack of an official Archive of Pagano’s work, the analysis of his work has been difficult and this explains the necessity to read the articles and the drawings published in the pages of «Casabella» and «Domus». As for the projects of Villa Colli and Casa a struttura d’acciaio, parts of the original drawings have been consulted. These drawings are not published and are kept in private archives of the collaborators of Pagano. The consultation of these documents has permitted the analysis of the cited works, which have been subject to a more complete reading following the different proposed solutions, which have permitted to understand the project path. The projects are analysed thought the method of comparison and critical reading which, specifically, means graphical elaborations and analytical schemes, mostly reconstructed on the basis of original projects but, where possible, also on a photographic investigation. The focus is on the project theme which, beginning with a specific living (dwelling) typology, finds variations because of the historico-political context in which Pagano is embedded and which partially shapes his research and theoretical thought, then translated in the built work. The analysis of the work follows, beginning, where possible, from a reconstruction of the evolution of the project as elaborated on the basis of the original documents and ending on an analysis of the constructive principles and composition. This second phase employs a methodology proposed by Pagano in his article Piante di ville, which, as expected, focuses on the plant as essential tool to identify the “true practical and poetic qualities of the construction”(Pagano, «Costruzioni-Casabella», 1940, p. 2). The reading of the project is integrated with the constructive analyses related to the technical aspects of the house which, in the case of Casa a struttura d’acciaio, play an important role in the project, while in Villa Colli and in Villa Caraccio are principally linked to the choice of materials for the construction of the different architectural elements. These are nonetheless key factors in the composition of the work. Future work could extend this reading to other house projects to deepen the research that could be completed with the consultation of Archival materials, which are missing at present. Finally, in the appendix I present a critical selection of the Pagano’s writings, which recall the themes discussed and embodied by the three projects. The texts have been selected among the articles published in Casabella and in other journals, completing the reading of the project work which cannot be detached from his theoretical thought. Moving from theory to project, we follow a path that brings us to define and deepen the central theme of the thesis: rational building as the principal feature of the architectural research of Pagano, which is paraphrased in multiple ways in his designed and built works.

Language and Embodiment: sensory-motor and linguistic-social experience. Evidence on sentence comprehension

In this work I address the study of language comprehension in an “embodied” framework. Firstly I show behavioral evidence supporting the idea that language modulates the motor system in a specific way, both at a proximal level (sensibility to the effectors) and at the distal level (sensibility to the goal of the action in which the single motor acts are inserted). I will present two studies in which the method is basically the same: we manipulated the linguistic stimuli (the kind of sentence: hand action vs. foot action vs. mouth action) and the effector by which participants had to respond (hand vs. foot vs. mouth; dominant hand vs. non-dominant hand). Response times analyses showed a specific modulation depending on the kind of sentence: participants were facilitated in the task execution (sentence sensibility judgment) when the effector they had to use to respond was the same to which the sentences referred. Namely, during language comprehension a pre-activation of the motor system seems to take place. This activation is analogous (even if less intense) to the one detectable when we practically execute the action described by the sentence. Beyond this effector specific modulation, we also found an effect of the goal suggested by the sentence. That is, the hand effector was pre-activated not only by hand-action-related sentences, but also by sentences describing mouth actions, consistently with the fact that to execute an action on an object with the mouth we firstly have to bring it to the mouth with the hand. After reviewing the evidence on simulation specificity directly referring to the body (for instance, the kind of the effector activated by the language), I focus on the specific properties of the object to which the words refer, particularly on the weight. In this case the hypothesis to test was if both lifting movement perception and lifting movement execution are modulated by language comprehension. We used behavioral and kinematics methods, and we manipulated the linguistic stimuli (the kind of sentence: the lifting of heavy objects vs. the lifting of light objects). To study the movement perception we measured the correlations between the weight of the objects lifted by an actor (heavy objects vs. light objects) and the esteems provided by the participants. To study the movement execution we measured kinematics parameters variance (velocity, acceleration, time to the first peak of velocity) during the actual lifting of objects (heavy objects vs. light objects). Both kinds of measures revealed that language had a specific effect on the motor system, both at a perceptive and at a motoric level. Finally, I address the issue of the abstract words. Different studies in the “embodied” framework tried to explain the meaning of abstract words The limit of these works is that they account only for subsets of phenomena, so results are difficult to generalize. We tried to circumvent this problem by contrasting transitive verbs (abstract and concrete) and nouns (abstract and concrete) in different combinations. The behavioral study was conducted both with German and Italian participants, as the two languages are syntactically different. We found that response times were faster for both the compatible pairs (concrete verb + concrete noun; abstract verb + abstract noun) than for the mixed ones. Interestingly, for the mixed combinations analyses showed a modulation due to the specific language (German vs. Italian): when the concrete word precedes the abstract one responses were faster, regardless of the word grammatical class. Results are discussed in the framework of current views on abstract words. They highlight the important role of developmental and social aspects of language use, and confirm theories assigning a crucial role to both sensorimotor and linguistic experience for abstract words.

Per un approccio semiotico ai videogiochi tra memoria culturale e memoria corporea

La tesi propone un approccio semiotico ai videogiochi e indaga le relazioni tra videogioco, memoria e senso, a partire dall’analisi di un ampio corpus di videogiochi, trasversale rispetto ai generi. Il lavoro intende mostrare la proficuità di un incontro tra semiotica e videogiochi sotto un duplice punto di vista: da un lato i videogiochi, in quanto oggetti “nuovi”, rappresentano un buon banco di prova per la teoria e la metodologia semiotica; dall’altro lato la semiotica permette di comprendere meglio i videogiochi, ricostruendo i meccanismi semiotici che contribuiscono a generare gli effetti di senso tipici di questa forma testuale (es. immersività, interattività, flusso…). Il lavoro si propone quindi il duplice obiettivo di individuare le peculiarità del videogioco in quanto oggetto di analisi semiotica (cap. 1) e i meccanismi che in diversi generi videoludici portano alla creazione di effetti di senso peculiari e alla costruzione di una nuova memoria (capp. 3, 4, 5). Il primo capitolo è dedicato a una riflessione teorica e metodologica che intende preparare il campo per l’analisi, provando a “testare” modelli, concetti e strumenti più o meno assestati con lo scopo di riconoscere lo statuto semiotico dei videogiochi e di individuare il modo migliore per analizzarli semioticamente. Inoltre nel cap. 1 si affrontano, ancora in un’ottica generale, le dinamiche tra memoria del gioco e memoria del giocatore e l’importanza dei processi di apprendimento per l’interpretazione videoludica. Gli ultimi tre capitoli sono invece dedicati ai risultati delle analisi, condotte su un corpus ampio di videogiochi, affiancato da un corpus “di controllo” costituito da video di partite concrete, immagini user-generated, interfacce fisiche di gioco e “discorsi su” i videogiochi inseriti nel corpus principale. Il terzo capitolo individua i meccanismi semiotici che contribuiscono a costruire, de-costruire e ricostruire l’identità del giocatore nel corso della partita. Il quarto capitolo affronta la relazione tra tempo del gioco e tempo del giocatore, concentrandosi sulle modalità di configurazione del tempo in atto nei diversi generi videoludici. L’ultimo capitolo è dedicato all’approfondimento di un aspetto particolare della testualità videoludica: la capacità dei videogiochi di generare esperienze embodied, cioè esperienze ‘incarnate’ e ‘situate’.

Negoziare confini: dagli stati di cose ai transiti

Negotiating boundaries: from state of affairs to matter of transit. The research deals with the everyday management of spatial uncertainty, starting with the wider historical question of terrains vagues (a French term for wastelands, dismantled areas and peripheral city voids, or interstitial spaces) and focusing later on a particular case study. The choice intended to privilege a small place (a mouth of a lagoon which crosses a beach), with ordinary features, instead of the esthetical “vague terrains”, often witnessed through artistic media or architectural reflections. This place offered the chance to explore a particular dimension of indeterminacy, mostly related with a certain kind of phenomenal instability of its limits, the hybrid character of its cultural status (neither natural, nor artificial) and its crossover position as a transitional space, between different tendencies and activities. The first theoretical part of the research develops a semiotic of vagueness, by taking under exam the structuralist idea of relation, in order to approach an interpretive notion of continuity and indeterminacy. This exploration highlights the key feature of actantial network distribution, which provides a bridge with the second methodological parts, dedicated to a “tuning” of the tools for the analysis. This section establishes a dialogue with current social sciences (like Actor-Network Theory, Situated action and Distributed Cognition), in order to define some observational methods for the documentation of social practices, which could be comprised in a semiotic ethnography framework. The last part, finally, focuses on the mediation and negotiation by which human actors are interacting with the varying conditions of the chosen environment, looking at people’s movements through space, their embodied dealings with the boundaries and the use of spatial artefacts as framing infrastructure of the site.

Designing and Programming Organizational Infrastructures for Agents situated in Artifact-based Environments

Actual trends in software development are pushing the need to face a multiplicity of diverse activities and interaction styles characterizing complex and distributed application domains, in such a way that the resulting dynamics exhibits some grade of order, i.e. in terms of evolution of the system and desired equilibrium. Autonomous agents and Multiagent Systems are argued in literature as one of the most immediate approaches for describing such a kind of challenges. Actually, agent research seems to converge towards the definition of renewed abstraction tools aimed at better capturing the new demands of open systems. Besides agents, which are assumed as autonomous entities purposing a series of design objectives, Multiagent Systems account new notions as first-class entities, aimed, above all, at modeling institutional/organizational entities, placed for normative regulation, interaction and teamwork management, as well as environmental entities, placed as resources to further support and regulate agent work. The starting point of this thesis is recognizing that both organizations and environments can be rooted in a unifying perspective. Whereas recent research in agent systems seems to account a set of diverse approaches to specifically face with at least one aspect within the above mentioned, this work aims at proposing a unifying approach where both agents and their organizations can be straightforwardly situated in properly designed working environments. In this line, this work pursues reconciliation of environments with sociality, social interaction with environment based interaction, environmental resources with organizational functionalities with the aim to smoothly integrate the various aspects of complex and situated organizations in a coherent programming approach. Rooted in Agents and Artifacts (A&A) meta-model, which has been recently introduced both in the context of agent oriented software engineering and programming, the thesis promotes the notion of Embodied Organizations, characterized by computational infrastructures attaining a seamless integration between agents, organizations and environmental entities.

Second law analysis and simulation techniques for the energy optimization of buildings

The research activity described in this thesis is focused mainly on the study of finite-element techniques applied to thermo-fluid dynamic problems of plant components and on the study of dynamic simulation techniques applied to integrated building design in order to enhance the energy performance of the building. The first part of this doctorate thesis is a broad dissertation on second law analysis of thermodynamic processes with the purpose of including the issue of the energy efficiency of buildings within a wider cultural context which is usually not considered by professionals in the energy sector. In particular, the first chapter includes, a rigorous scheme for the deduction of the expressions for molar exergy and molar flow exergy of pure chemical fuels. The study shows that molar exergy and molar flow exergy coincide when the temperature and pressure of the fuel are equal to those of the environment in which the combustion reaction takes place. A simple method to determine the Gibbs free energy for non-standard values of the temperature and pressure of the environment is then clarified. For hydrogen, carbon dioxide, and several hydrocarbons, the dependence of the molar exergy on the temperature and relative humidity of the environment is reported, together with an evaluation of molar exergy and molar flow exergy when the temperature and pressure of the fuel are different from those of the environment. As an application of second law analysis, a comparison of the thermodynamic efficiency of a condensing boiler and of a heat pump is also reported. The second chapter presents a study of borehole heat exchangers, that is, a polyethylene piping network buried in the soil which allows a ground-coupled heat pump to exchange heat with the ground. After a brief overview of low-enthalpy geothermal plants, an apparatus designed and assembled by the author to carry out thermal response tests is presented. Data obtained by means of in situ thermal response tests are reported and evaluated by means of a finite-element simulation method, implemented through the software package COMSOL Multyphysics. The simulation method allows the determination of the precise value of the effective thermal properties of the ground and of the grout, which are essential for the design of borehole heat exchangers. In addition to the study of a single plant component, namely the borehole heat exchanger, in the third chapter is presented a thorough process for the plant design of a zero carbon building complex. The plant is composed of: 1) a ground-coupled heat pump system for space heating and cooling, with electricity supplied by photovoltaic solar collectors; 2) air dehumidifiers; 3) thermal solar collectors to match 70% of domestic hot water energy use, and a wood pellet boiler for the remaining domestic hot water energy use and for exceptional winter peaks. This chapter includes the design methodology adopted: 1) dynamic simulation of the building complex with the software package TRNSYS for evaluating the energy requirements of the building complex; 2) ground-coupled heat pumps modelled by means of TRNSYS; and 3) evaluation of the total length of the borehole heat exchanger by an iterative method developed by the author. An economic feasibility and an exergy analysis of the proposed plant, compared with two other plants, are reported. The exergy analysis was performed by considering the embodied energy of the components of each plant and the exergy loss during the functioning of the plants.

Macchine esperienziali: Narrativa, cognizione e atto di lettura

La mia tesi si riallaccia al dibattito teorico-letterario contemporaneo sulla possibilità di un approccio cognitivo alla narrativa e alla letteratura in particolare. Essa si propone di esplorare il rapporto tra narrazione ed esperienza, ridefinendo il concetto di “esperienzialità” della narrativa introdotto da Monika Fludernik nel suo Towards a “Natural” Narratology (1996). A differenza di Fludernik, che ha identificato l’esperienzialità con la rappresentazione dell’esperienza dei personaggi, la mia trattazione assegna un ruolo di primo piano al lettore, cercando di rispondere alla domanda: perché leggere una storia è – o si costituisce come – un’esperienza? L’intuizione dietro tutto ciò è che le teorizzazioni dell’esperienza e della coscienza nella filosofia della mente degli ultimi venti anni possano gettare luce sull’interazione tra lettori e testi narrativi. Il mio punto di riferimento principale è la scienza cognitiva “di seconda generazione”, secondo cui l’esperienza è un relazionarsi attivo e corporeo al mondo. La prima parte del mio studio è dedicata all’intreccio tra la narrativa e quello che chiamo lo “sfondo esperienziale” di ogni lettore, un repertorio di esperienze già note ai lettori attraverso ripetute interazioni con il mondo fisico e socio-culturale. Mi soffermo inoltre sul modo in cui relazionarsi a un testo narrativo può causare cambiamenti e slittamenti in questo sfondo esperienziale, incidendo sulla visione del mondo del lettore. Mi rivolgo poi al coinvolgimento corporeo del lettore, mostrando che la narrativa può attingere allo sfondo esperienziale dei suoi fruitori anche sul piano dell’esperienza di base: le simulazioni corporee della percezione contribuiscono alla nostra comprensione delle storie, incidendo sia sulla ricostruzione dello spazio dell’ambientazione sia sulla relazione intersoggettiva tra lettori e personaggi. Infine, mi occupo del rapporto tra l’esperienza della lettura e la pratica critico-letteraria dell’interpretazione, sostenendo che – lungi dal costituire due modalità opposte di fruizione dei testi – esse sono intimamente connesse.

Regolazione delle prestazioni indispensabili e poteri della Commissione di garanzia

La legge n. 146 del 1990 ha istituito la Commissione di garanzia per l’attuazione della legge sullo sciopero nei servizi pubblici essenziali, un’authority deputata al controllo dell’effettivo bilanciamento del diritto di sciopero con gli altri diritti della persona di rango costituzionale nel caso dei servizi pubblici essenziali. Ad essa spettano alcuni poteri tra di loro eterogenei. Accanto a poteri propulsivi e sanzionatori, essa possiede poteri di tipo normativo. La legge prevede, infatti, che le prestazioni indispensabili e le altre misure necessarie al contemperamento siano determinate da accordi tra il datore di lavoro e le associazioni sindacali, mentre per il lavoro autonomo da codici di autoregolamentazione forniti da ognuna delle categorie interessate. Gli accordi e i codici di autoregolamentazione devono essere, comunque, sottoposti al vaglio della Commissione di garanzia la quale in ultimo stabilisce se essi siano idonei a realizzare il bilanciamento dei diritti in questione. Quando i soggetti indicati dalla legge non provvedano alla redazione dei suddetti atti, la Commissione interviene con l’emanazione di una provvisoria regolamentazione, la quale possiede natura di regolamento, giacchè partecipa dei caratteri della generalità ed astrattezza propri delle norme di legge. In effetti, anche altre authorities possiedono un potere normativo, che si sostanzia alle volte in un regolamento indipendente, altre in un regolamento simile ai regolamenti delegati ed altre al regolamento esecutivo. Poiché la legge n. 146 del 1990 prevede quali siano gli istituti idonei a realizzare il bilanciamento (preavviso, proclamazione scritta, procedure di raffreddamento e conciliazione, intervallo minimo, misure indicative delle prestazioni indispensabili), la provvisoria regolamentazione possiede i caratteri del regolamento esecutivo.

Essays on Bank Risk

This PhD Thesis is composed of three chapters, each discussing a specific type of risk that banks face. The first chapter talks about Systemic Risk and how banks get exposed to it through the Interbank Funding Market. Exposures in the said market have Systemic Risk implications because the market creates linkages, where the failure of one party can affect the others in the market. By showing that CDS Spreads, as bank risk indicators, are positively related to their Net Interbank Funding Market Exposures, this chapter establishes the above Systemic Risk Implications of Interbank Funding. Meanwhile, the second chapter discusses how banks may handle Illiquidity Risk, defined as the possibility of having sudden funding needs. Illiquidity Risk is embodied in this chapter through Loan Commitments as they oblige banks to lend to its clients, up to a certain amount of funds at any time. This chapter points out that using Securitization as funding facility, could allow the banks to manage this Illiquidity Risk. To make this case, this chapter demonstrates empirically that banks having an increase in Loan Commitments, may experience an increase in risk profile but such can be offset by an accompanying increase in Securitization Activity. Lastly, the third chapter focuses on how banks manage Credit Risk also through Securitization. Securitization has a Credit Risk management property by allowing the offloading of risk. This chapter investigates how banks use such property by looking at the effect of securitization on the banks’ loan portfolios and overall risk and returns. The findings are that securitization is positively related to loan portfolio size and the portfolio share of risky loans, which translates to higher risk and returns. Thus, this chapter points out that Credit Risk management through Securitization may be have been done towards higher risk taking for high returns.

Social Cognition: New Insights from Affordance and Simon Effects

The perspective of the present project can be inscribed in the so-called “Social Cognition” framework, that in the last years moved from a focus on the individual mind toward embodied and participatory aspects of social understanding. Among the topics relevant for social cognition, the aim of the thesis was to shed more light on motor resonance and joint action, by using two well-known effects of cognitive psychology: “Affordance” and “Simon”. In the first part of the project, the Affordance effect has been considered, starting from Gibson to some post-Gibsonian theorizations. Particular attention has received the notion of “Micro-affordance”. The theoretical and empirical overview allows to understand how it can be possible to use the affordance effect to investigate the issue of motor resonance. A first study employed a priming paradigm and explored both in adults and school-age children the influence of a micro-affordance that can be defined dangerousness, and how motor resonance develops. The second part of the thesis focused on the Simon effect, starting with the presentation of the “stimulus–response (S–R) compatibility effect” to introduce the “Simon effect”. Particular attention has been dedicated to recent studies on the “joint Simon effect”. The reviewed empirical findings have been discussed in a wider theoretical perspective on joint action. The second study was aimed at investigating whether shared representations, as indexed by the presence of the joint Simon effect, are modulated by minimal ingroup–outgroup distinctions and by experienced interdependence between participants. The third study explored to what extent prior experience could modulate performance in task sharing, combining two paradigms of cognitive psychology, the joint Simon and the joint transfer-of-learning. In a general discussion the results obtained in the three studies have been summarized, emphasizing their original contribution and their importance within the Social Cognition research.

Una prospettiva storico-filosofica sull'evoluzione del curricolo di fisica nella scuola: problemi e innovazioni pedagogiche

Negli ultimi vent’anni sono state proposte al livello internazionale alcune analisi dei problemi per le scienze nella scuola e diverse strategie per l’innovazione didattica. Molte ricerche hanno fatto riferimento a una nuova nozione di literacy scientifica, quale sapere fondamentale dell’educazione, indipendente dalle scelte professionali successive alla scuola. L’ipotesi di partenza di questa ricerca sostiene che alcune di queste analisi e l’idea di una nuova literacy scientifica di tipo non-vocazionale mostrino notevoli limiti quando rapportate al contesto italiano. Le specificità di quest’ultimo sono state affrontate, innanzitutto, da un punto di vista comparativo, discutendo alcuni documenti internazionali sull’insegnamento delle scienze. Questo confronto ha messo in luce la difficoltà di ottenere un insieme di evidenze chiare e definitive sui problemi dell’educazione scientifica discussi da questi documenti, in particolare per quanto riguarda i dati sulla crisi delle vocazioni scientifiche e sull’attitudine degli studenti verso le scienze. Le raccomandazioni educative e alcuni progetti curricolari internazionali trovano degli ostacoli decisivi nella scuola superiore italiana anche a causa di specificità istituzionali, come particolari principi di selezione e l’articolazione dei vari indirizzi formativi. Il presente lavoro si è basato soprattutto su una ricostruzione storico-pedagogica del curricolo di fisica, attraverso l’analisi delle linee guida nazionali, dei programmi di studio e di alcuni rappresentativi manuali degli ultimi decenni. Questo esame del curricolo “programmato” ha messo in luce, primo, il carattere accademico della fisica liceale e la sua debole rielaborazione culturale e didattica, secondo, l’impatto di temi e problemi internazionali sui materiali didattici. Tale impatto ha prodotto dei cambiamenti sul piano delle finalità educative e degli strumenti di apprendimento incorporati nei manuali. Nonostante l’evoluzione di queste caratteristiche del curricolo, tuttavia, l’analisi delle conoscenze storico-filosofiche utilizzate dai manuali ha messo in luce la scarsa contestualizzazione culturale della fisica quale uno degli ostacoli principali per l’insegnamento di una scienza più rilevante e formativa.

Integration of MFA and LCA methodologies: the anthropogenic aluminium cycle in Italy

MFA and LCA methodologies were applied to analyse the anthropogenic aluminium cycle in Italy with focus on historical evolution of stocks and flows of the metal, embodied GHG emissions, and potentials from recycling to provide key features to Italy for prioritizing industrial policy toward low-carbon technologies and materials. Historical trend series were collected from 1947 to 2009 and balanced with data from production, manufacturing and waste management of aluminium-containing products, using a ‘top-down’ approach to quantify the contemporary in-use stock of the metal, and helping to identify ‘applications where aluminium is not yet being recycled to its full potential and to identify present and future recycling flows’. The MFA results were used as a basis for the LCA aimed at evaluating the carbon footprint evolution, from primary and electrical energy, the smelting process and the transportation, embodied in the Italian aluminium. A discussion about how the main factors, according to the Kaya Identity equation, they did influence the Italian GHG emissions pattern over time, and which are the levers to mitigate it, it has been also reported. The contemporary anthropogenic reservoirs of aluminium was estimated at about 320 kg per capita, mainly embedded within the transportation and building and construction sectors. Cumulative in-use stock represents approximately 11 years of supply at current usage rates (about 20 Mt versus 1.7 Mt/year), and it would imply a potential of about 160 Mt of CO2eq emissions savings. A discussion of criticality related to aluminium waste recovery from the transportation and the containers and packaging sectors was also included in the study, providing an example for how MFA and LCA may support decision-making at sectorial or regional level. The research constitutes the first attempt of an integrated approach between MFA and LCA applied to the aluminium cycle in Italy.

Tecnica, stile e ideologia nella musica sinfonica in video: la Quinta Sinfonia di Beethoven

Oggetto di questo lavoro è un’analisi dettagliata di un campione ristretto di riprese televisive della Quinta Sinfonia di Beethoven, con l’obiettivo di far emergere il loro meccanismo costruttivo, in senso sia tecnico sia culturale. Premessa dell’indagine è che ciascuna ripresa sia frutto di un’autorialità specifica che si sovrappone alle due già presenti in ogni esecuzione della Quinta Sinfonia, quella del compositore e quella dell’interprete, definita perciò «terza autorialità» riassumendo nella nozione la somma di contributi specifici che portano alla produzione di una ripresa (consulente musicale, regista, operatori di ripresa). La ricerca esamina i rapporti che volta a volta si stabiliscono fra i tre diversi piani autoriali, ma non mira a una ricostruzione filologica: l’obiettivo non è ricostruire le intenzioni dell’autore materiale quanto di far emergere dall’esame della registrazione della ripresa, così com’è data a noi oggi (spesso in una versione già più volte rimediata, in genere sotto forma di dvd commercializzato), scelte tecniche, musicali e culturali che potevano anche essere inconsapevoli. L’analisi dettagliata delle riprese conferma l’ipotesi di partenza che ci sia una sorta di sistema convenzionale, quasi una «solita forma» o approccio standardizzato, che sottende la gran parte delle riprese; gli elementi che si possono definire convenzionali, sia per la presenza sia per la modalità di trattamento, sono diversi, ma sono soprattutto due gli aspetti che sembrano esserne costitutivi: il legame con il rito del concerto, che viene rispettato e reincarnato televisivamente, con la costruzione di una propria, specifica aura; e la presenza di un paradigma implicito e sostanzialmente ineludibile che pone la maggior parte delle riprese televisive entro l’alveo della concezione della musica classica come musica pura, astratta, che deve essere compresa nei suoi propri termini.

Ground penetrating radar early-time technique for soil electromagnetic parameters estimation

In recent years, thanks to the technological advances, electromagnetic methods for non-invasive shallow subsurface characterization have been increasingly used in many areas of environmental and geoscience applications. Among all the geophysical electromagnetic methods, the Ground Penetrating Radar (GPR) has received unprecedented attention over the last few decades due to its capability to obtain, spatially and temporally, high-resolution electromagnetic parameter information thanks to its versatility, its handling, its non-invasive nature, its high resolving power, and its fast implementation. The main focus of this thesis is to perform a dielectric site characterization in an efficient and accurate way studying in-depth a physical phenomenon behind a recent developed GPR approach, the so-called early-time technique, which infers the electrical properties of the soil in the proximity of the antennas. In particular, the early-time approach is based on the amplitude analysis of the early-time portion of the GPR waveform using a fixed-offset ground-coupled antenna configuration where the separation between the transmitting and receiving antenna is on the order of the dominant pulse-wavelength. Amplitude information can be extracted from the early-time signal through complex trace analysis, computing the instantaneous-amplitude attributes over a selected time-duration of the early-time signal. Basically, if the acquired GPR signals are considered to represent the real part of a complex trace, and the imaginary part is the quadrature component obtained by applying a Hilbert transform to the GPR trace, the amplitude envelope is the absolute value of the resulting complex trace (also known as the instantaneous-amplitude). Analysing laboratory information, numerical simulations and natural field conditions, and summarising the overall results embodied in this thesis, it is possible to suggest the early-time GPR technique as an effective method to estimate physical properties of the soil in a fast and non-invasive way.
