Securitization and Special Purpose Vehicles in an International Setting: a Systemic View

The present work tries to display a comprehensive and comparative study of the different legal and regulatory problems involved in international securitization transactions. First, an introduction to securitization is provided, with the basic elements of the transaction, followed by the different varieties of it, including dynamic securitization and synthetic securitization structures. Together with this introduction to the intricacies of the structure, a insight into the influence of securitization in the financial and economic crisis of 2007-2009 is provided too; as well as an overview of the process of regulatory competition and cooperation that constitutes the framework for the international aspects of securitization. The next Chapter focuses on the aspects that constitute the foundations of structured finance: the inception of the vehicle, and the transfer of risks associated to the securitized assets, with particular emphasis on the validity of those elements, and how a securitization transaction could be threatened at its root. In this sense, special importance is given to the validity of the trust as an instrument of finance, to the assignment of future receivables or receivables in block, and to the importance of formalities for the validity of corporations, trusts, assignments, etc., and the interaction of such formalities contained in general corporate, trust and assignment law with those contemplated under specific securitization regulations. Then, the next Chapter (III) focuses on creditor protection aspects. As such, we provide some insights on the debate on the capital structure of the firm, and its inadequacy to assess the financial soundness problems inherent to securitization. Then, we proceed to analyze the importance of rules on creditor protection in the context of securitization. The corollary is in the rules in case of insolvency. In this sense, we divide the cases where a party involved in the transaction goes bankrupt, from those where the transaction itself collapses. Finally, we focus on the scenario where a substance over form analysis may compromise some of the elements of the structure (notably the limited liability of the sponsor, and/or the transfer of assets) by means of veil piercing, substantive consolidation, or recharacterization theories. Once these elements have been covered, the next Chapters focus on the regulatory aspects involved in the transaction. Chapter IV is more referred to “market” regulations, i.e. those concerned with information disclosure and other rules (appointment of the indenture trustee, and elaboration of a rating by a rating agency) concerning the offering of asset-backed securities to the public. Chapter V, on the other hand, focuses on “prudential” regulation of the entity entrusted with securitizing assets (the so-called Special Purpose vehicle), and other entities involved in the process. Regarding the SPV, a reference is made to licensing requirements, restriction of activities and governance structures to prevent abuses. Regarding the sponsor of the transaction, a focus is made on provisions on sound originating practices, and the servicing function. Finally, we study accounting and banking regulations, including the Basel I and Basel II Frameworks, which determine the consolidation of the SPV, and the de-recognition of the securitized asset from the originating company’s balance-sheet, as well as the posterior treatment of those assets, in particular by banks. Chapters VI-IX are concerned with liability matters. Chapter VI is an introduction to the different sources of liability. Chapter VII focuses on the liability by the SPV and its management for the information supplied to investors, the management of the asset pool, and the breach of loyalty (or fiduciary) duties. Chapter VIII rather refers to the liability of the originator as a result of such information and statements, but also as a result of inadequate and reckless originating or servicing practices. Chapter IX finally focuses on third parties entrusted with the soundness of the transaction towards the market, the so-called gatekeepers. In this respect, we make special emphasis on the liability of indenture trustees, underwriters and rating agencies. Chapters X and XI focus on the international aspects of securitization. Chapter X contains a conflicts of laws analysis of the different aspects of structured finance. In this respect, a study is made of the laws applicable to the vehicle, to the transfer of risks (either by assignment or by means of derivatives contracts), to liability issues; and a study is also made of the competent jurisdiction (and applicable law) in bankruptcy cases; as well as in cases where a substance-over-form is performed. Then, special attention is also devoted to the role of financial and securities regulations; as well as to their territorial limits, and extraterritoriality problems involved. Chapter XI supplements the prior Chapter, for it analyzes the limits to the States’ exercise of regulatory power by the personal and “market” freedoms included in the US Constitution or the EU Treaties. A reference is also made to the (still insufficient) rules from the WTO Framework, and their significance to the States’ recognition and regulation of securitization transactions.

Scienza, Tecnica, Politica: Il Problema del Metodo nel Pensiero di Jacopo Aconcio

The aim of this PhD thesis is to study accurately and in depth the figure and the literary production of the intellectual Jacopo Aconcio. This minor author of the 16th century has long been considered a sort of “enigmatic character”, a profile which results from the work of those who, for many centuries, have left his writing to its fate: a story of constant re-readings and equally incessant oversights. This is why it is necessary to re-read Aconcio’s production in its entirety and to devote to it a monographic study. Previous scholars’ interpretations will obviously be considered, but at the same time an effort will be made to go beyond them through the analysis of both published and manuscript sources, in the attempt to attain a deeper understanding of the figure of this man, who was a Christian, a military and hydraulic engineer and a political philosopher,. The title of the thesis was chosen to emphasise how, throughout the three years of the doctorate, my research concentrated in equal measure and with the same degree of importance on all the reflections and activities of Jacopo Aconcio. My object, in fact, was to establish how and to what extent the methodological thinking of the intellectual found application in, and at the same time guided, his theoretical and practical production. I did not mention in the title the author’s religious thinking, which has always been considered by everyone the most original and interesting element of his production, because religion, from the Reformation onwards, was primarily a political question and thus it was treated by almost all the authors involved in the Protestant movement - Aconcio in the first place. Even the remarks concerning the private, intimate sphere of faith have therefore been analysed in this light: only by acknowledging the centrality of the “problem of politics” in Aconcio’s theories, in fact, is it possible to interpret them correctly. This approach proves the truth of the theoretical premise to my research, that is to say the unity and orderliness of the author’s thought: in every field of knowledge, Aconcio applies the rules of the methodus resolutiva, as a means to achieve knowledge and elaborate models of pacific cohabitation in society. Aconcio’s continuous references to method can make his writing pedant and rather complex, but at the same time they allow for a consistent and valid analysis of different disciplines. I have not considered the fact that most of his reflections appear to our eyes as strongly conditioned by the time in which he lived as a limit. To see in him, as some have done, the forerunner of Descartes’ methodological discourse or, conversely, to judge his religious theories as not very modern, is to force the thought of an author who was first and foremost a Christian man of his own time. Aconcio repeats this himself several times in his writings: he wants to provide individuals with the necessary tools to reach a full-fledged scientific knowledge in the various fields, and also to enable them to seek truth incessantly in the religious domain, which is the duty of every human being. The will to find rules, instruments, effective solutions characterizes the whole of the author’s corpus: Aconcio feels he must look for truth in all the arts, aware as he is that anything can become science as long as it is analysed with method. Nevertheless, he remains a man of his own time, a Christian convinced of the existence of God, creator and governor of the world, to whom people must account for their own actions. To neglect this fact in order to construct a “character”, a generic forerunner, but not participant, of whatever philosophical current, is a dangerous and sidetracking operation. In this study, I have highlighted how Aconcio’s arguments only reveal their full meaning when read in the context in which they were born, without depriving them of their originality but also without charging them with meanings they do not possess. Through a historical-doctrinal approach, I have tried to analyse the complex web of theories and events which constitute the substratum of Aconcio’s reflection, in order to trace the correct relations between texts and contexts. The thesis is therefore organised in six chapters, dedicated respectively to Aconcio’s biography, to the methodological question, to the author’s engineering activity, to his historical knowledge and to his religious thinking, followed by a last section concerning his fortune throughout the centuries. The above-mentioned complexity is determined by the special historical moment in which the author lived. On the one hand, thanks to the new union between science and technique, the 16th century produces discoveries and inventions which make available a previously unthinkable number of notions and lead to a “revolution” in the way of studying and teaching the different subjects, which, by producing a new form of intellectual, involved in politics but also aware of scientific-technological issues, will contribute to the subsequent birth of modern science. On the other, the 16th century is ravaged by religious conflicts, which shatter the unity of the Christian world and generate theological-political disputes which will inform the history of European states for many decades. My aim is to show how Aconcio’s multifarious activity is the conscious fruit of this historical and religious situation, as well as the attempt of an answer to the request of a new kind of engagement on the intellectual’s behalf. Plunged in the discussions around methodus, employed in the most important European courts, involved in the abrupt acceleration of technical-scientific activities, and especially concerned by the radical religious reformation brought on by the Protestant movement, Jacopo Aconcio reflects this complex conjunction in his writings, without lacking in order and consistency, differently from what many scholars assume. The object of this work, therefore, is to highlight the unity of the author’s thought, in which science, technique, faith and politics are woven into a combination which, although it may appear illogical and confused, is actually tidy and methodical, and therefore in agreement with Aconcio’s own intentions and with the specific characters of European culture in the Renaissance. This theory is confirmed by the reading of the Ars muniendorum oppidorum, Aconcio’s only work which had been up till now unavailable. I am persuaded that only a methodical reading of Aconcio’s works, without forgetting nor glorifying any single one, respects the author’s will. From De methodo (1558) onwards, all his writings are summae, guides for the reader who wishes to approach the study of the various disciplines. Undoubtedly, Satan’s Stratagems (1565) is something more, not only because of its length, but because it deals with the author’s main interest: the celebration of doubt and debate as bases on which to build religious tolerance, which is the best method for pacific cohabitation in society. This, however, does not justify the total centrality which the Stratagems have enjoyed for centuries, at the expense of a proper understanding of the author’s will to offer examples of methodological rigour in all sciences. Maybe it is precisely because of the reforming power of Aconcio’s thought that, albeit often forgotten throughout the centuries, he has never ceased to reappear and continues to draw attention, both as a man and as an author. His ideas never stop stimulating the reader’s curiosity and this may ultimately be the best demonstration of their worth, independently from the historical moment in which they come back to the surface.

Drugstore Bologna. Una lettura del rapporto tra la città e la droga

The main task of this research is to investigate the situation of drugs in the city of Bologna. A first discussion pertains the method to adopt studying an ethical question as drug actually is. In fact it is widely known that drugs problem involves many political and religious considerations which are misleading in a scientific point of view. After a methodological chapter supposed to show the purpose of this research, it is discussed a logical definition of drugs. There it is examined an aristotelian definition of drugs with semantic instruments from philosophy of the language to fulfil meaning of terms. The following chapter discusses personal stories of different people involved in drug in the city, who actually represent the main characters of drug subculture. Afterwards the official statistics concerning drug enforcement is discussed and compared with a specific police action which allows to criticize that data, and to make some hypothesis about drug quantities circulating in town. Next step is investigating drugs addicted in town, with a validation technique of data base queries. The result is a statistics of users in which there is evidence of main presence of foreigners and not resident Italians who use to practice drugs in this city. Demographic analysis of identified people shows that drug addiction is widely diffused among all range of age and mainly pertains males, with an increasing trend. Then is examined the geographic distribution of users residence and use places, showing that drugs abuse is spread among all classes of population, while drugs squares are located in some points of town which realise a kind of drug area with a concentration of dealers not organised together. With some detailed queries in police reports statistics is studied some specific subject on nowadays drug abuse, the phenomenon of multi-use, the relation between drug and crime, the relation between drug and mental disease, recording some evidence in such topics. Finally a survey on city media along last two years shows the interest about this topic and gives an idea of public opinion’s information about drugs. The study refers to the city of Bologna only, and pertains data recorded along last ten years by the local metropolitan police corp.

"Water users must be efficient producers". Women's access to and use of land in Chókwè irrigation scheme, Mozambique

The irrigation scheme Eduardo Mondlane, situated in Chókwè District - in the Southern part of the Gaza province and within the Limpopo River Basin - is the largest in the country, covering approximately 30,000 hectares of land. Built by the Portuguese colonial administration in the 1950s to exploit the agricultural potential of the area through cash-cropping, after Independence it became one of Frelimo’s flagship projects aiming at the “socialization of the countryside” and at agricultural economic development through the creation of a state farm and of several cooperatives. The failure of Frelimo’s economic reforms, several infrastructural constraints and local farmers resistance to collective forms of production led to scheme to a state of severe degradation aggravated by the floods of the year 2000. A project of technical rehabilitation initiated after the floods is currently accompanied by a strong “efficiency” discourse from the managing institution that strongly opposes the use of irrigated land for subsistence agriculture, historically a major livelihood strategy for smallfarmers, particularly for women. In fact, the area has been characterized, since the end of the XIX century, by a stable pattern of male migration towards South African mines, that has resulted in an a steady increase of women-headed households (both de jure and de facto). The relationship between land reform, agricultural development, poverty alleviation and gender equality in Southern Africa is long debated in academic literature. Within this debate, the role of agricultural activities in irrigation schemes is particularly interesting considering that, in a drought-prone area, having access to water for irrigation means increased possibilities of improving food and livelihood security, and income levels. In the case of Chókwè, local governments institutions are endorsing the development of commercial agriculture through initiatives such as partnerships with international cooperation agencies or joint-ventures with private investors. While these business models can sometimes lead to positive outcomes in terms of poverty alleviation, it is important to recognize that decentralization and neoliberal reforms occur in the context of financial and political crisis of the State that lacks the resources to efficiently manage infrastructures such as irrigation systems. This kind of institutional and economic reforms risk accelerating processes of social and economic marginalisation, including landlessness, in particular for poor rural women that mainly use irrigated land for subsistence production. The study combines an analysis of the historical and geographical context with the study of relevant literature and original fieldwork. Fieldwork was conducted between February and June 2007 (where I mainly collected secondary data, maps and statistics and conducted preliminary visit to Chókwè) and from October 2007 to March 2008. Fieldwork methodology was qualitative and used semi-structured interviews with central and local Government officials, technical experts of the irrigation scheme, civil society organisations, international NGOs, rural extensionists, and water users from the irrigation scheme, in particular those women smallfarmers members of local farmers’ associations. Thanks to the collaboration with the Union of Farmers’ Associations of Chókwè, she has been able to participate to members’ meeting, to education and training activities addressed to women farmers members of the Union and to organize a group discussion. In Chókwè irrigation scheme, women account for the 32% of water users of the familiar sector (comprising plot-holders with less than 5 hectares of land) and for just 5% of the private sector. If one considers farmers’ associations of the familiar sector (a legacy of Frelimo’s cooperatives), women are 84% of total members. However, the security given to them by the land title that they have acquired through occupation is severely endangered by the use that they make of land, that is considered as “non efficient” by the irrigation scheme authority. Due to a reduced access to marketing possibilities and to inputs, training, information and credit women, in actual fact, risk to see their right to access land and water revoked because they are not able to sustain the increasing cost of the water fee. The myth of the “efficient producer” does not take into consideration the characteristics of inequality and gender discrimination of the neo-liberal market. Expecting small-farmers, and in particular women, to be able to compete in the globalized agricultural market seems unrealistic, and can perpetuate unequal gendered access to resources such as land and water.

Previdenza complementare: evoluzione e tendenze

La tesi si articola in tre capitoli. Il primo dà conto del dibattito sorto attorno alla problematica dell’inquadramento della previdenza complementare nel sistema costituzionale dell’art. 38 Cost. che ha diviso la dottrina tra quanti hanno voluto ricondurre tale fenomeno al principio di libertà della previdenza privata di cui all’ art. 38, comma 5, Cost. e quanti lo hanno invece collocato al 2° comma della stessa norma, sulla base di una ritenuta identità di funzioni tra previdenza pubblica e previdenza complementare. Tale ultima ricostruzione in particolare dopo la c.d. Riforma “Amato” è culminata nella giurisprudenza della Corte Costituzionale, che ha avuto modo di pronunciarsi sulla questione con una serie di pronunce sulla vicenda del c.d. “contributo sul contributo” e su quella della subordinazione dei requisiti di accesso alle prestazioni pensionistiche complementari alla maturazione dei requisiti previsti dal sistema obbligatorio. Il capitolo successivo si occupa della verifica della attualità e della coerenza dell’impostazione della Corte Costituzionale alla luce dell’evoluzione della disciplina dei fondi pensione. Nel terzo capitolo, infine, vengono affrontate alcune questioni aperte in relazione ai c.d. fondi pensione “preesistenti” suscettibili di sollevare preoccupazioni circa la necessità di garantire le aspettative e i diritti dei soggetti iscritti.

Testo e memoria tra semiotica e scienze cognitive: una situazione sperimentale intorno al ricordo di un film

The research project presented in this dissertation is about text and memory. The title of the work is "Text and memory between Semiotics and Cognitive Science: an experimental setting about remembering a movie". The object of the research is the relationship between texts or "textuality" - using a more general semiotic term - and memory. The goal is to analyze the link between those semiotic artifacts that a culture defines as autonomous meaningful objects - namely texts - and the cognitive performance of memory that allows to remember them. An active dialogue between Semiotics and Cognitive Science is the theoretical paradigm in which this research is set, the major intend is to establish a productive alignment between the "theory of text" developed in Semiotics and the "theory of memory" outlined in Cognitive Science. In particular the research is an attempt to study how human subjects remember and/or misremember a film, as a specific case study; in semiotics, films are “cinematographic texts”. The research is based on the production of a corpus of data gained through the qualitative method of interviewing. After an initial screening of a fulllength feature film each participant of the experiment has been interviewed twice, according to a pre-established set of questions. The first interview immediately after the screening: the subsequent, follow-up interview three months from screening. The purpose of this design is to elicit two types of recall from the participants. In order to conduce a comparative inquiry, three films have been used in the experimental setting. Each film has been watched by thirteen subjects, that have been interviewed twice. The corpus of data is then made by seventy-eight interviews. The present dissertation displays the results of the investigation of these interviews. It is divided into six main parts. Chapter one presents a theoretical framework about the two main issues: memory and text. The issue of the memory is introduced through many recherches drown up in the field of Cognitive Science and Neuroscience. It is developed, at the same time, a possible relationship with a semiotic approach. The theoretical debate about textuality, characterizing the field of Semiotics, is examined in the same chapter. Chapter two deals with methodology, showing the process of definition of the whole method used for production of the corpus of data. The interview is explored in detail: how it is born, what are the expected results, what are the main underlying hypothesis. In Chapter three the investigation of the answers given by the spectators starts. It is examined the phenomenon of the outstanding details of the process of remembering, trying to define them in a semiotic way. Moreover there is an investigation of the most remembered scenes in the movie. Chapter four considers how the spectators deal with the whole narrative. At the same time it is examined what they think about the global meaning of the film. Chapter five is about affects. It tries to define the role of emotions in the process of comprehension and remembering. Chapter six presents a study of how the spectators account for a single scene of the movie. The complete work offers a broad perspective about the semiotic issue of textuality, using both a semiotic competence and a cognitive one. At the same time it presents a new outlook on the issue of memory, opening several direction of research.

Sostanzialismo e relazionalismo dello spaziotempo alla luce della relatività generale

Until recently the debate on the ontology of spacetime had only a philosophical significance, since, from a physical point of view, General Relativity has been made "immune" to the consequences of the "Hole Argument" simply by reducing the subject to the assertion that solutions of Einstein equations which are mathematically different and related by an active diffeomorfism are physically equivalent. From a technical point of view, the natural reading of the consequences of the "Hole Argument” has always been to go further and say that the mathematical representation of spacetime in General Relativity inevitably contains a “superfluous structure” brought to light by the gauge freedom of the theory. This position of apparent split between the philosophical outcome and the physical one has been corrected thanks to a meticulous and complicated formal analysis of the theory in a fundamental and recent (2006) work by Luca Lusanna and Massimo Pauri entitled “Explaining Leibniz equivalence as difference of non-inertial appearances: dis-solution of the Hole Argument and physical individuation of point-events”. The main result of this article is that of having shown how, from a physical point of view, point-events of Einstein empty spacetime, in a particular class of models considered by them, are literally identifiable with the autonomous degrees of freedom of the gravitational field (the Dirac observables, DO). In the light of philosophical considerations based on realism assumptions of the theories and entities, the two authors then conclude by saying that spacetime point-events have a degree of "weak objectivity", since they, depending on a NIF (non-inertial frame), unlike the points of the homogeneous newtonian space, are plunged in a rich and complex non-local holistic structure provided by the “ontic part” of the metric field. Therefore according to the complex structure of spacetime that General Relativity highlights and within the declared limits of a methodology based on a Galilean scientific representation, we can certainly assert that spacetime has got "elements of reality", but the inevitably relational elements that are in the physical detection of point-events in the vacuum of matter (highlighted by the “ontic part” of the metric field, the DO) are closely dependent on the choice of the global spatiotemporal laboratory where the dynamics is expressed (NIF). According to the two authors, a peculiar kind of structuralism takes shape: the point structuralism, with common features both of the absolutist and substantival tradition and of the relationalist one. The intention of this thesis is that of proposing a method of approaching the problem that is, at least at the beginning, independent from the previous ones, that is to propose an approach based on the possibility of describing the gravitational field at three distinct levels. In other words, keeping the results achieved by the work of Lusanna and Pauri in mind and following their underlying philosophical assumptions, we intend to partially converge to their structuralist approach, but starting from what we believe is the "foundational peculiarity" of General Relativity, which is that characteristic inherent in the elements that constitute its formal structure: its essentially geometric nature as a theory considered regardless of the empirical necessity of the measure theory. Observing the theory of General Relativity from this perspective, we can find a "triple modality" for describing the gravitational field that is essentially based on a geometric interpretation of the spacetime structure. The gravitational field is now "visible" no longer in terms of its autonomous degrees of freedom (the DO), which, in fact, do not have a tensorial and, therefore, nor geometric nature, but it is analyzable through three levels: a first one, called the potential level (which the theory identifies with the components of the metric tensor), a second one, known as the connections level (which in the theory determine the forces acting on the mass and, as such, offer a level of description related to the one that the newtonian gravitation provides in terms of components of the gravitational field) and, finally, a third level, that of the Riemann tensor, which is peculiar to General Relativity only. Focusing from the beginning on what is called the "third level" seems to present immediately a first advantage: to lead directly to a description of spacetime properties in terms of gauge-invariant quantites, which allows to "short circuit" the long path that, in the treatises analyzed, leads to identify the "ontic part” of the metric field. It is then shown how to this last level it is possible to establish a “primitive level of objectivity” of spacetime in terms of the effects that matter exercises in extended domains of spacetime geometrical structure; these effects are described by invariants of the Riemann tensor, in particular of its irreducible part: the Weyl tensor. The convergence towards the affirmation by Lusanna and Pauri that the existence of a holistic, non-local and relational structure from which the properties quantitatively identified of point-events depend (in addition to their own intrinsic detection), even if it is obtained from different considerations, is realized, in our opinion, in the assignment of a crucial role to the degree of curvature of spacetime that is defined by the Weyl tensor even in the case of empty spacetimes (as in the analysis conducted by Lusanna and Pauri). In the end, matter, regarded as the physical counterpart of spacetime curvature, whose expression is the Weyl tensor, changes the value of this tensor even in spacetimes without matter. In this way, going back to the approach of Lusanna and Pauri, it affects the DOs evolution and, consequently, the physical identification of point-events (as our authors claim). In conclusion, we think that it is possible to see the holistic, relational, and non-local structure of spacetime also through the "behavior" of the Weyl tensor in terms of the Riemann tensor. This "behavior" that leads to geometrical effects of curvature is characterized from the beginning by the fact that it concerns extensive domains of the manifold (although it should be pointed out that the values of the Weyl tensor change from point to point) by virtue of the fact that the action of matter elsewhere indefinitely acts. Finally, we think that the characteristic relationality of spacetime structure should be identified in this "primitive level of organization" of spacetime.

Tecniche numeriche di studio della sicurezza stradale: il caso della provincia di Bologna

La tesi dottorale in oggetto prende spunto da alcune considerazioni di base relative alla salute di una comunità. Infatti quest’ultima si fonda sulla sicurezza dell’ambiente in cui vive e sulla qualità delle relazioni tra i suoi componenti. In questo ambito la mobilità rappresenta uno degli elementi di maggior criticità, sia per la sicurezza delle persone, che per la salute pubblica, che per le conseguenze sull’ambiente che ne derivano. Negli ultimi anni la circolazione stradale è notevolmente aumentata è questo ha portato a notevoli aspetti negativi, uno dei quali è connesso agli incidenti stradali. In tale ambito viene ricordato che l’Unione Europea ha da tempo indicato come obiettivo prioritario il miglioramento della sicurezza stradale e nel 2001 ha fissato il traguardo di dimezzare entro il 2010 il numero delle vittime degli incidenti stradali. Non ultima, l’approvazione da parte del Parlamento europeo e del Consiglio di un atto legislativo (d’imminente pubblicazione sulla GU Europea) relativo alla gestione della sicurezza in tutte le fasi della pianificazione, della progettazione e del funzionamento delle infrastrutture stradali, in cui si evidenzia l’esigenza di una quantificazione della sicurezza stradale. In tale contesto viene sottolineato come uno dei maggiori problemi nella gestione della sicurezza stradale sia la mancanza di un metodo affidabile per stimare e quantificare il livello di sicurezza di una strada esistente o in progetto. Partendo da questa considerazione la tesi si sviluppa mettendo in evidenza le grandezza fondamentali nel problema della sicurezza stradale, (grado di esposizione, rischio d’incidente e le possibili conseguenze sui passeggeri) e analizzando i sistemi adottati tradizionalmente per effettuare analisi di sicurezza: • Statistiche dei dati storici d’incidente; • Previsione da modelli basati su analisi di regressione dei dati incidentali; • Studi Before-After; • Valutazione da giudizi di esperti. Dopo aver analizzato gli aspetti positivi e negativi delle alternative in parola, viene proposto un nuovo approccio, che combina gli elementi di ognuno dei metodi sopra citati in un algoritmo di previsione incidentale. Tale nuovo algoritmo, denominato Interactive Highway Safety Design Model (IHSDM) è stato sviluppato dalla Federal Highway Administration in collaborazione con la Turner Fairbank Higway Research Center ed è specifico per le strade extraurbane a due corsie. Il passo successivo nello sviluppo della tesi è quello di un’analisi dettagliata del modello IHSDM che fornisce il numero totale di incidenti previsti in un certo intervallo temporale. Viene analizzata la struttura del modello, i limiti d’applicabilità, le equazioni che ne sono alla base e i coefficienti moltiplicativi relativi ad ogni caratteristica geometrica e funzionale. Inoltre viene presentata un’ampia analisi di sensibilità che permette di definire quale sia l’influenza d’ogni singolo Fattore di Previsione incidentale (Accident Predication Factor) sul risultato finale. Dai temi trattati, emerge chiaramente come la sicurezza è legata a più sistemi tra loro interconnessi e che per utilizzare e migliorare i modelli previsionali è necessario avere a disposizione dati completi, congruenti, aggiornati e facilmente consultabili. Infatti, anche quando sono disponibili elementi su tutti gli incidenti avvenuti, spesso mancano informazioni di dettaglio ma fondamentali, riguardanti la strada come ad esempio il grado di curvatura, la larghezza della carreggiata o l’aderenza della pavimentazione. In tale ottica, nella tesi viene presentato il Sistema Informativo Stradale (SIS) della Provincia di Bologna, concepito come strumento di gestione delle problematiche inerenti la viabilità e come strumento di supporto per la pianificazione degli interventi e la programmazione delle risorse da investire sulla rete. Viene illustrato come il sistema sia in grado di acquisire, elaborare ed associare dati georeferenziati relativi al territorio sia sotto forma di rappresentazioni grafiche, sia mediante informazioni descrittive di tipo anagrafico ed alfanumerico. Quindi viene descritto il rilievo ad alto rendimento, effettuato con l’ausilio di un laboratorio mobile multifunzionale (Mobile Mapping System), grazie al quale è stato possibile definire con precisione il grafo completo delle strade provinciali e il database contenente i dati relativi al patrimonio infrastrutturale. Tali dati, relativi alle caratteristiche plano-altimetriche dell’asse (rettifili, curve planimetriche, livellette, raccordi altimetrici, ecc...), alla sezione trasversale (numero e larghezza corsie, presenza di banchine, ecc..), all’ambiente circostante e alle strutture annesse vengono presentati in forma completa specificando per ognuno la variabilità specifica. Inoltre viene evidenziato come il database si completi con i dati d’incidentali georeferenziati sul grafo e compresivi di tutte le informazioni contenute nel modello ISTAT CTT/INC spiegandone le possibili conseguenze sul campo dell’analisi di sicurezza. La tesi si conclude con l’applicazione del modello IHSDM ad un caso reale, nello specifico la SP255 di S.Matteo Decima. Infatti tale infrastruttura sarà oggetto di un miglioramento strutturale, finanziato dalla Regione Emilia Romagna, che consistente nell’allargamento della sede stradale attraverso la realizzazione di una banchina pavimentata di 1.00m su entrambi i lati della strada dalla prog. km 19+000 al km 21+200. Attraverso l’utilizzo dell’algoritmo di previsione incidentale è stato possibile quantificare gli effetti di questo miglioramento sul livello di sicurezza dell’infrastruttura e verificare l’attendibilità del modello con e senza storia incidentale pregressa. Questa applicazione ad un caso reale mette in evidenza come le informazioni del SIS possano essere sfruttate a pieno per la realizzazione di un analisi di sicurezza attraverso l’algoritmo di previsione incidentale IHSDM sia nella fase di analisi di uno specifico tronco stradale che in quella fondamentale di calibrazione del modello ad una specifica rete stradale (quella della Provincia di Bologna). Inoltre viene sottolineato come la fruibilità e la completezza dei dati a disposizione, possano costituire la base per sviluppi di ricerca futuri, come ad esempio l’indagine sulle correlazioni esistenti tra le variabili indipendenti che agiscono sulla sicurezza stradale.

Arti decorative: Bologna e Faenza tra Ottocento e Novecento

La ricerca approfondisce gli studi iniziati dalla dott.ssa Baldini in occasione della tesi di laurea e amplia le indagini critiche avviate per la mostra sull’Aemilia Ars (2001). La ricerca si è interessata alle aree di Bologna e di Faenza individuando le connessioni che tra Otto e Novecento intercorrono tra la cultura artistica locale e quella nazionale ed europea. Nasce infatti in questo periodo Aemilia Ars, uno dei più innovativi movimenti del contesto nazionale nel campo delle arti decorative. I membri del gruppo, raccoltisi intorno alla carismatica figura di Alfonso Rubbiani nei primi anni Ottanta, sono attratti da influenze nordeuropee e sin dall’inizio si mostrano orientati a seguire precetti ruskiniani e preraffaelliti. Molto importante in entrambe le città, per l’evoluzione dello scenario artistico e artigianale – in questi anni più che mai unite in un rapporto di strettissima correlazione – è l’apporto e il sostegno offerto dai salotti, dai circoli, dai caffè e dai cenacoli locali. Dal punto di vista dello stile, forme lineari con una marcata tendenza all’astrazione caratterizzano la produzione dei principali interpreti faentini e bolognesi dell’ultimo ventennio dell’Ottocento allineandoli con le ricerche dei loro contemporanei nel resto d’Europa. I settori produttivi che si sono indagati sono quelli della ceramica, dell’ebanisteria, dei ferri battuti, dell’oreficeria, delle arti tessili e dei cuoi. Gran parte di queste lavorazioni – attardatesi nella realizzazione di oggetti dalle forme di ispirazione seicentesca, certamente poco adatte alla produzione industriale – subiscono ora una decisa accelerazione verso forme più svelte che, adeguandosi alla possibilità di riproduzione seriale degli oggetti, si diffonderanno quasi capillarmente tra l’aristocrazia e la borghesia, faticando tuttavia a raggiungere le classi meno abbienti a causa degli elevati costi di produzione. Nell’ultima parte viene tracciato sinteticamente il quadro delle attività artistiche e artigianali faentine del periodo indicato, con una particolare attenzione all’opera delle personalità afferenti al Cenacolo baccariniano.

La memoria risorgimentale in Giustizia e Libertà (1929-1940)

The dissertation regards The memory on the Italian Risorgimento in “Justice and Freedom”(1929-1940) a theoretical core point in the history of the Movement, which so far has not been granted due attention. The work herewith presented is therefore aimed at filling a storiographical gap, analysing the historical events which continue to operate as traditions, raising feelings and passions and hence operating in politics, although as secondary factors. The point made is that the Justice and Freedom Movement, an antifascist political movement born in Paris in October 1929, bases its strength on the heroic choice of the antifascism movement to fight a Second Risorgimento, connecting the fight against the regime to the battles previously fought for the justice and the freedom, an entirely isolated event in the political opposition’s panorama. The dissertation, thus, attempts to explain how and why Justice and Freedom is so tightly interconnected in its political action to the Risorgimento tradition. The first chapter sets the cultural background of the foundation of the Justice and Freedom Movement. The centre of such foundation was Florence, where Gaetano Salvemini, along with a group of young people, would later on carry out some cultural experiences that ideally prepare the ground for the movement’s birth. In the second chapter are found the sites of the memory where the passage of the Risorgimento tradition between the generations takes place. The work therefore shifts from a public to a private level, concentrating on biographical paths. The choice made was for Nello Rosselli, a man very close to the Justice and Freedom Movement but who, as opposed to his comrades-in-arms, did not chose the political way to express his ethical choice, but rather the theoretical one, becoming a Risorgimento historian. The third chapter concentrates on the birth of the Justice and Freedom Movement in France, trying to reconstruct the cultural ties and the confrontation places and sites where the members of the Movement could interact with the French intellectual milieu, bringing back to light the propagandistic usage of the Risorgimento myth carried out by the Movement. Lastly, the fourth chapter focuses on the cultural debate on the Risorgimento, which took place on the press organs of the Movement, pointing out and periodizing the theoretical passages and the propagandistic uses of the myth as related to the stages of the Movement and the political needs.
