Un’analisi statistico – economica dell’impatto delle norme WHO su nutrizione e salute

I comportamenti nutrizionali stanno assumendo sempre maggiore rilievo all’interno delle politiche comunitarie e questo sottolinea che la dieta sta avendo, negli ultimi anni, una maggiore importanza come fattore di causa e allo stesso tempo prevenzione nella diffusione di malattie croniche come il cancro, malattie cardiovascolari, diabete, osteoporosi e disturbi dentali. Numerosi studi mostrano infatti che i tassi di obesità sono triplicati nelle ultime due decadi e si è stimato che, se i livelli di obesità continueranno a crescere allo stesso tasso del 1990, nel 2010 il numero di persone obese raggiungerà i 150 milioni tra gli adulti e i 15 milioni tra bambini e adolescenti. I governi nazionali stanno quindi cercando di risolvere questo problema, a cui sono inoltre legati alti costi nazionali, tramite l’implementazione di politiche nutrizionali. Analisi di tipo cross-section sono già state evidenziate da studiosi come Schmidhuber e Traill (2006), i quali hanno effettuato un’analisi di convergenza a livello europeo per esaminare la distanza tra le calorie immesse da 426 prodotti diversi. In quest’analisi hanno così dimostrato la presenza di una similarità distinta e crescente tra i paesi europei per quanto riguarda la composizione della dieta. Srinivasan et al. invece hanno osservato la relazione esistente tra ogni singolo prodotto alimentare consumato e le norme nutrizionali dell’ Organizzazione Mondiale della Sanità (World Health Organization, WHO) Lo scopo di questa tesi è quello di evidenziare il problema a livello di aggregati nutritivi e di specifiche componenti nutrizionali come zucchero, frutta e verdura e non relativamente ad ogni singolo prodotto consumato. A questo proposito ci si è basati sulla costruzione di un indicatore (Recommendation Compliance Index) in modo da poter misurare le distanze tra la dieta media e le raccomandazioni del WHO. Lo scopo è quindi quello di riuscire a quantificare il fenomeno del peggioramento della dieta in diverse aree del mondo negli ultimi quattro decenni, tramite un’analisi panel, basandosi sui dati sui nutrienti consumati, provenienti dal database della FAO (e precisamente dal dataset Food Balance Sheets – FBS). Nella prima fase si introduce il problema dell’obesità e delle malattie croniche correlate, evidenziando dati statistici in diversi paesi europei e mondiali. Si sottolineano inoltre le diverse azioni dei governi e del WHO, tramite l’attuazione di campagne contro l’obesità e in favore di una vita più salutare e di una maggiore attività fisica. Nella seconda fase si è costruito un indicatore aggregato (Recommendation Compliance Index) in modo da analizzare le caratteristiche nella dieta dei diversi Paesi a livello mondiale rispetto alle norme del WHO. L’indicatore si basa sui dati ottenuti da FAOSTAT ed è calcolato per 149 paesi del database dell’FBS per il periodo 1961-2002. Nell’analisi si sono utilizzati i dati sulle percentuali di energia prodotta dalle varie componenti nutritive, quali grassi, grassi saturi e transaturi, zuccheri, carboidrati, proteine e le quantità di frutta e verdura consumate. Inoltre si è applicato un test statistico per testare se il valore del RCI è significativamente cambiato nel tempo, prendendo in considerazione gruppi di Paesi (Paesi OECD, Paesi in via di sviluppo e sottosviluppati). Si è voluto poi valutare la presenza o meno di un processo di convergenza, applicando l’analisi di σ-convergenza per osservare ad esempio se la variabilità è diminuita nel tempo in modo significativo. Infine si è applicato l’indicatore ad un livello micro, utilizzando il database del National Diet and Nutrition Survey, che raccoglie dati di macrocomponenti nutritive e misure antropometriche della popolazione inglese dai 16 ai 64 anni per il periodo 2000-2001. Si sono quindi effettuate analisi descrittive nonché analisi di correlazione, regressione lineare e ordinale per osservare le relazioni tra l’indicatore, i macronutrienti, il reddito e le misure antropometriche dell’ Indice di Massa Corporea (Body Mass Index, BMI) e del rapporto vita-fianchi (Waist-hip ratio, WHR).

Competitività in sostenibilità urbana e territoriale. L’Emilia Romagna, regione d’Europa

The thesis in Urban and Regional Geography titled “URBAN AND TERRITORIAL COMPETITIVENESS IN SUSTAINABILITY. EMILIA-ROMAGNA, REGION OF EUROPE” is divided into two sections. Section one is additionally composed by two chapters (chap. 1 and 2) and deals with theoretical and gnosiological issues. Section two, of two more chapters (chap. 3 and 4), provides practical contributions: these issues give explanatory patterns to interpret the performances of emiliano-romagnoli urban systems. Chapter one is an introductory chapter. It analyzes globalization that involves a larger and larger number of cities, rich or poor. It also considers the so called “digital divide” either as one of the major phenomena of this unhomogeneous development or as an interesting gnosiological and practical challenge of geography. Globalization is now involving all the cities, large or small, but the small ones have higher risks of exclusion: it depends on their more fragile socio-economic, cultural, and environmental urban structure. That’s why European Union (chapter two) promotes policies and endows politics to sustain cities, because urban systems are the basis for the territorial development. So, European, national and local Institutions are firmly interested in promoting urban and local interventions and projects. Section two deals with economic-geography methods, which consists on collecting indicators and the benchmarking methodology. It also specifically analyzes the urban systems of Emilia-Romagna. Consequences of the globalization on the cities are interpreted with a study of their local resources, intended as potentials for their development. The STeMA approach, proposed by Professor Maria Prezioso (University of Roma, “Tor Vergata”) and used by the ESPON (European Spatial Program Observation Network) project, describes the main “determinants” of the territorial and urban development. These are easily comparable to one another (similar or better performing). This approach achieves two goals. On one hand, it is possible to analyze every urban system in its all main characteristics and to preserve its historical and cultural factors. On another hand, each city is “knowable” and “understandable” by all scholars, as it is objectively comparable. So, urban planners can propose specific “multi-level” and “multi-varied” programs of governance. These will face globalization by exalting local empowerment.

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.

Il processo migratorio come determinante della salute mentale: l'esperienza del Centro di Consultazione Socio-Culturale nel Distretto di Pianura Est, AUSL di Bologna.

La ricerca in oggetto ha analizzato le relazioni tra migrazione e salute mentale nel Distretto di Pianura Est dell'AUSL di Bologna. Attraverso un dispositivo d’indagine multi-disciplinare basato sui quadri teorici dell'Antropologia Medica Critica, della Salute Pubblica e della Psichiatria, la ricerca si è inserita nell’ampio contesto di sperimentazione di un innovativo modello di assistenza per pazienti migranti, denominato Centro di Consultazione Socio- Culturale. L'architettura dello studio si rifà a un modello di Ricerca-Azione Partecipata e Multi-Situata fondato su un approccio analitico e auto-riflessivo, il quale ha consentito di problematizzare, oltre alle azioni e alle traiettorie dei vari soggetti che operano nel campo della ricerca, anche le categorie oggetto della ricerca stessa. L'analisi, profondamente radicata nel dato empirico, è stata condotta a partire dall'esperienza degli attori sociali coinvolti. Le esperienze, le informazioni e le rappresentazioni reciproche sono state co-costruite in forma partecipativa attraverso l'uso combinato di metodologie quali-quantitative proprie sia delle discipline sanitarie sia di quelle sociali. Come materiali della ricerca sono stati utilizzati: dati primari e secondari prodotti dalle istituzioni e dalle organizzazioni del territorio stesso; informazioni provenienti dall'osservazione partecipante; colloqui con informatori-chiave; interviste semi-strutturate con decisori politici, amministratori, organizzazioni del territorio, operatori dei servizi, cittadini e pazienti. La ricerca ha dimostrato la validità delle prospettive teoriche utilizzate e delle strategie di lavoro proposte. Il modello di lavoro multi-disciplinare e multi-metodologico si è rivelato produttivo nell'indagare congiuntamente le prospettive degli attori coinvolti insieme alle loro traiettorie, alle reciproche interconnessioni e alle relazioni tra processi locali e globali. L’analisi auto-riflessiva ha consentito di analizzare le attività del Centro di Consultazione evidenziandone vantaggi e limiti. Infine, la collaborazione tra Salute Pubblica e Antropologia Medica Critica ha dimostrato una grande potenzialità e produttività sia sul versante della ricerca scientifica sia su quello dell'assistenza sanitaria.

Essays on Atypicality: A narrative perspective to illuminate how atypical actors can counter the disciplining effect of categories

Using Big Data and Natural Language Processing (NLP) tools, this dissertation investigates the narrative strategies that atypical actors can leverage to deal with the adverse reactions they often elicit. Extensive research shows that atypical actors, those who fail to abide by established contextual standards and norms, are subject to skepticism and face a higher risk of rejection. Indeed, atypical actors combine features and behaviors in unconventional ways, thereby generating confusion in the audience and instilling doubts about their propositions' legitimacy. However, the same atypicality is often cited as the precursor to socio-cultural innovation and a strategic act to expand the capacity for delivering valued goods and services. Contextualizing the conditions under which atypicality is celebrated or punished has been a significant theoretical challenge for scholars interested in reconciling this tension. Nevertheless, prior work has focused on audience side factors or on actor-side characteristics that are only scantily under an actor's control (e.g., status and reputation). This dissertation demonstrates that atypical actors can use strategically crafted narratives to mitigate against the audience’s negative response. In particular, when atypical actors evoke conventional features in their story, they are more likely to overcome the illegitimacy discount usually applied to them. Moreover, narratives become successful navigational devices for atypicality when atypical actors use a more abstract language. This simplifies classification and provides the audience with more flexibility to interpret and understand them.

Mind the gaps: cognitive-inspired AI for high-level visual sensemaking. Towards abstract concept image classification

The abundance of visual data and the push for robust AI are driving the need for automated visual sensemaking. Computer Vision (CV) faces growing demand for models that can discern not only what images "represent," but also what they "evoke." This is a demand for tools mimicking human perception at a high semantic level, categorizing images based on concepts like freedom, danger, or safety. However, automating this process is challenging due to entropy, scarcity, subjectivity, and ethical considerations. These challenges not only impact performance but also underscore the critical need for interoperability. This dissertation focuses on abstract concept-based (AC) image classification, guided by three technical principles: situated grounding, performance enhancement, and interpretability. We introduce ART-stract, a novel dataset of cultural images annotated with ACs, serving as the foundation for a series of experiments across four key domains: assessing the effectiveness of the end-to-end DL paradigm, exploring cognitive-inspired semantic intermediaries, incorporating cultural and commonsense aspects, and neuro-symbolic integration of sensory-perceptual data with cognitive-based knowledge. Our results demonstrate that integrating CV approaches with semantic technologies yields methods that surpass the current state of the art in AC image classification, outperforming the end-to-end deep vision paradigm. The results emphasize the role semantic technologies can play in developing both effective and interpretable systems, through the capturing, situating, and reasoning over knowledge related to visual data. Furthermore, this dissertation explores the complex interplay between technical and socio-technical factors. By merging technical expertise with an understanding of human and societal aspects, we advocate for responsible labeling and training practices in visual media. These insights and techniques not only advance efforts in CV and explainable artificial intelligence but also propel us toward an era of AI development that harmonizes technical prowess with deep awareness of its human and societal implications.

Transatlantic regulatory divergence in pharmaceuticals: exploring economic and cultural explanations

The analysis delves into the regulatory divergence between the EU and the US in the pharmaceutical sector. Through law and economics, political science, and cultural theory perspectives, the study explores how collective preferences within each jurisdiction shape regulations. By identifying cultural orientations such as individualism in the US and hierarchy in the EU, the research suggests that underlying cultural factors play a significant role in regulatory decisions. Despite calls for regulatory harmonization, the recognition of legitimate differences in preferences due to cultural diversity emphasizes that uniformity may not always be the best solution, showcasing the importance of understanding cultural influences in shaping regulatory landscapes.
