Sorveglianza dell'influenza aviare: studio di un sistema di rilevazione precoce della circolazione virale in popolazioni di volatili selvatici

The emergency of infection by highly pathogenic avian influenza virus (HPAI) subtype H5N1 has focused the attention of the world scientific community, requiring the prompt provision of effective control systems for early detection of the circulation of low pathogenic influenza H5 viruses (LPAI) in populations of wild birds to prevent outbreaks of highly pathogenic (HPAI) in populations of domestic birds with possible transmission to humans. The project stems from the aim to provide, through a preliminary analysis of data obtained from surveillance in Italy and Europe, a preliminary study about the virus detection rates and the development of mathematical models, an objective assessment of the effectiveness of avian influenza surveillance systems in wild bird populations, and to point out guidelines to support the planning process of the sampling activities. The results obtained from the statistical processing quantify the sampling effort in terms of time and sample size required, and simulating different epidemiological scenarios identify active surveillance as the most suitable for endemic LPAI infection monitoring in wild waterfowl, and passive surveillance as the only really effective tool in early detecting HPAI H5N1 circulation in wild populations. Given the lack of relevant information on H5N1 epidemiology, and the actual finantial and logistic constraints, an approach that makes use of statistical tools to evaluate and predict monitoring activities effectiveness proves to be of primary importance to direct decision-making and make the best use of available resources.

Sintesi di catalizzatori supportati Pd/Cu e studio della loro reattività per l'idrodeclorurazione di molecole clorofluorurate

Il Protocollo di Montreal, che succede alla Convenzione di Vienna per la protezione dello strato di ozono richiede l’eliminazione di idrocarburi contenenti cloro (CFC). Nel corso degli ultimi decenni ha quindi assunto importanza la reazione di idrodeclorurazione di clorofluorocarburi, in particolare rivolta alla produzione di idrocarburi fluorurati che sono risultati interessanti per la produzione di polimeri con specifiche caratteristiche di resistenza meccanica, termica e chimica. In questo lavoro di tesi, svolto in collaborazione con SOLVAY SPECIALTY POLYMERS ITALY, sono stati studiati catalizzatori innovativi per la produzione di perfluorometilviniletere (MVE), mediante idrodeclorurazione di perfluorometilcloroviniletere (AM). Attualmente la reazione di produzione industriale dell’MVE, condotta con l'utilizzo di quantità stechiometriche di Zn e dimetilformammide (DMF), presenta il notevole problema dello smaltimento di grandi quantità di zinco cloruro e di DMF. La reazione studiata, condotta in catalisi eterogenea, in presenta di H2, presenta una forte dipendenza dalla natura dei metalli utilizzati oltre che dal tipo di sintesi dei catalizzatori impiegati. Nell'ambito di questo lavoro è stato sviluppato un metodo, a basso impatto ambientale, per la sintesi si nanoparticelle preformate da utilizzare per la preparazione di catalizzatori supportati si TiO2 e SiO2. Le nanosospensioni ed i sistemi catalitici prodotti sono stati caratterizzati utilizzando diverse metodologie di analisi quali: XRD, XRF, TEM, TPR-MS, che hanno permesso di ottimizzare le diverse fasi della preparazione. Allo scopo di osservare effetti sinergici tra le specie utilizzate sono stati confrontati sistemi catalitici monometallici con sistemi bimetallici, rivelando interessanti implicazioni derivanti dall’utilizzo di fasi attive nanoparticellari a base di Pd e Cu. In particolare, è stato possibile apprezzare miglioramenti significativi nelle prestazioni catalitiche in termini di selettività a perfluorometilviniletere all’aumentare del contenuto di Cu. La via di sintesi ottimizzata e impiegata per la produzione di nanoparticelle bimetalliche è risultata una valida alternativa, a basso impatto ambientale, ai metodi di sintesi normalmente usati, portando alla preparazione di catalizzatori maggiormente attivi di quelli preparati con i metalli standard.

Da alleati vittoriosi ad acerrimi rivali: i processi di ri-allineamento dopo i conflitti egemonici. Teorie a confronto e studio di casi

Why some powers manage to coordinate their security efforts while others confront each other as rivals is still one of the most relevant and debated questions in the field of IR theory. The dissertation wants to give a contribution to this important debate. In particular, the main goal of the research is to analyse the dynamics of great power interactions after the end of hegemonic conflicts, that is to understand why, following the defeat of the common enemies, some of the winning allies continue to cooperate, while others begin to engage in political and military competition. In order to understand this difference, the study compares the explanatory value of two rival theoretical perspectives: neorealism, in its main version of the balance of power framework, and a liberal approach focused on domestic politics. The thesis is divided in two sections. In the first, I do summarize the main assumptions and predictions of the theories, from which I derive two different sets of hypotheses on the evolution of post-war great power relations. In the second part, I test the hypotheses by focusing on two cases of post-war alignment dynamics: 1) the relations among Austria, Prussia, Russia, Great Britain and France after the Napoleonic wars; 2) the relations among the US, the UK, France and Italy after the end of WWI. The historical cases disconfirm the logic of the balance of power and confirm the liberal hypotheses, seeing that the results of the analysis show changes in the domestic structures of the great powers had a much larger impact on the emergence of new alliances and rivalries than did the international distribution of power. In the conclusion of the dissertation, I provide the reader with a discussion of the main theoretical implications of the empirical findings.

Very Long Baseline Interferometry in Italy Wide-field VLBI imaging and astrometry and prospects for an Italian VLBI network including the Sardinia Radio Telescope

In this thesis the use of widefield imaging techniques and VLBI observations with a limited number of antennas are explored. I present techniques to efficiently and accurately image extremely large UV datasets. Very large VLBI datasets must be reduced into multiple, smaller datasets if today’s imaging algorithms are to be used to image them. I present a procedure for accurately shifting the phase centre of a visibility dataset. This procedure has been thoroughly tested and found to be almost two orders of magnitude more accurate than existing techniques. Errors have been found at the level of one part in 1.1 million. These are unlikely to be measurable except in the very largest UV datasets. Results of a four-station VLBI observation of a field containing multiple sources are presented. A 13 gigapixel image was constructed to search for sources across the entire primary beam of the array by generating over 700 smaller UV datasets. The source 1320+299A was detected and its astrometric position with respect to the calibrator J1329+3154 is presented. Various techniques for phase calibration and imaging across this field are explored including using the detected source as an in-beam calibrator and peeling of distant confusing sources from VLBI visibility datasets. A range of issues pertaining to wide-field VLBI have been explored including; parameterising the wide-field performance of VLBI arrays; estimating the sensitivity across the primary beam both for homogeneous and heterogeneous arrays; applying techniques such as mosaicing and primary beam correction to VLBI observations; quantifying the effects of time-average and bandwidth smearing; and calibration and imaging of wide-field VLBI datasets. The performance of a computer cluster at the Istituto di Radioastronomia in Bologna has been characterised with regard to its ability to correlate using the DiFX software correlator. Using existing software it was possible to characterise the network speed particularly for MPI applications. The capabilities of the DiFX software correlator, running on this cluster, were measured for a range of observation parameters and were shown to be commensurate with the generic performance parameters measured. The feasibility of an Italian VLBI array has been explored, with discussion of the infrastructure required, the performance of such an array, possible collaborations, and science which could be achieved. Results from a 22 GHz calibrator survey are also presented. 21 out of 33 sources were detected on a single baseline between two Italian antennas (Medicina to Noto). The results and discussions presented in this thesis suggest that wide-field VLBI is a technique whose time has finally come. Prospects for exciting new science are discussed in the final chapter.

Percorsi di gender performance: fotografia tra arte e moda dagli anni Novanta ad oggi

My project explores and compares different forms of gender performance in contemporary art and visual culture according to a perspective centered on photography. Thanks to its attesting power this medium can work as a ready-made. In fact during the 20th century it played a key role in the cultural emancipation of the body which (using a Michel Foucault’s expression) has now become «the zero point of the world». Through performance the body proves to be a living material of expression and communication while photography ensures the recording of any ephemeral event that happens in time and space. My questioning approach considers the gender constructed imagery from the 1990s to the present in order to investigate how photography’s strong aura of realism promotes and allows fantasies of transformation. The contemporary fascination with gender (especially for art and fashion) represents a crucial issue in the global context of postmodernity and is manifested in a variety of visual media, from photography to video and film. Moreover the internet along with its digital transmission of images has deeply affected our world (from culture to everyday life) leading to a postmodern preference for performativity over the more traditional and linear forms of narrativity. As a consequence individual borders get redefined by the skin itself which (dissected through instant vision) turns into a ductile material of mutation and hybridation in the service of identity. My critical assumptions are taken from the most relevant changes occurred in philosophy during the last two decades as a result of the contributions by Jacques Lacan, Michel Foucault, Jacques Derrida, Gilles Deleuze who developed a cross-disciplinary and comparative approach to interpret the crisis of modernity. They have profoundly influenced feminist studies so that the category of gender has been reassessed in contrast with sex (as a biological connotation) and in relation to history, culture, society. The ideal starting point of my research is the year 1990. I chose it as the approximate historical moment when the intersection of race, class and gender were placed at the forefront of international artistic production concerned with identity, diversity and globalization. Such issues had been explored throughout the 1970s but it was only from the mid-1980s onward that they began to be articulated more consistently. Published in 1990, the book "Gender trouble: feminism and the subversion of identity" by Judith Butler marked an important breakthrough by linking gender to performance as well as investigating the intricate connections between theory and practice, embodiment and representation. It inspired subsequent research in a variety of disciplines, art history included. In the same year Teresa de Lauretis launched the definition of queer theory to challenge the academic perspective in gay and lesbian studies. In the meantime the rise of Third Wave Feminism in the US introduced a racially and sexually inclusive vision over the global situation in order to reflect on subjectivity, new technologies and popular culture in connection with gender representation. These conceptual tools have enabled prolific readings of contemporary cultural production whether fine arts or mass media. After discussing the appropriate framework of my project and taking into account the postmodern globalization of the visual, I have turned to photography to map gender representation both in art and in fashion. Therefore I have been creating an archive of images around specific topics. I decided to include fashion photography because in the 1990s this genre moved away from the paradigm of an idealized and classical beauty toward a new vernacular allied with lifestyles, art practices, pop and youth culture; as one might expect the dominant narrative modes in fashion photography are now mainly influenced by cinema and snapshot. These strategies originate story lines and interrupted narratives using models’ performance to convey a particular imagery where identity issues emerge as an essential part of fashion spectacle. Focusing on the intersections of gender identities with socially and culturally produced identities, my approach intends to underline how the fashion world has turned to current trends in art photography and in some case turned to the artists themselves. The growing fluidity of the categories that distinguish art from fashion photography represents a particularly fruitful moment of visual exchange. Varying over time the dialogue between these two fields has always been vital; nowadays it can be studied as a result of this close relationship between contemporary art world and consumer culture. Due to the saturation of postmodern imagery the feedback between art and fashion has become much more immediate and then increasingly significant for anyone who wants to investigate the construction of gender identity through performance. In addition to that a lot of magazines founded in the 1990s bridged the worlds of art and fashion because some of their designers and even editors were art-school graduates encouraging innovation. The inclusion of art within such magazines aimed at validating them as a form of art in themselves supporting a dynamic intersection for music, fashion, design and youth culture: an intersection that also contributed to create and spread different gender stereotypes. This general interest in fashion produced many exhibitions of and about fashion itself at major international venues such as the Victoria and Albert Museum in London, the Metropolitan Museum of Art and the Solomon R. Guggenheim Museum in New York. Since then this celebrated success of fashion has been regarded as a typical element of postmodern culture. Owing to that I have also based my analysis on some important exhibitions dealing with gender performance like "Féminin-Masculin" at the Centre Pompidou of Paris (1995), "Rrose is a Rrose is a Rrose. Gender performance in photography" at the Solomon R. Guggenheim Museum of New York (1997), "Global Feminisms" at the Brooklyn Museum (2007), "Female Trouble" at the Pinakothek der Moderne in München together with the workshops dedicated to "Performance: gender and identity" in June 2005 at the Tate Modern of London. Since 2003 in Italy we have had Gender Bender - an international festival held annually in Bologna - to explore the gender imagery stemming from contemporary culture. In few days this festival offers a series of events ranging from visual arts, performance, cinema, literature to conferences and music. Being aware that any method of research is neither race nor gender neutral I have traced these critical paths to question gender identity in a multicultural perspective taking account of the political implications too. In fact, if visibility may be equated with exposure, we can also read these images as points of intersection of visibility with social power. Since gender assignations rely so heavily on the visual, the postmodern dismantling of gender certainty through performance has wide-ranging effects that need to be analyzed. In some sense this practice can even contest the dominance of visual within postmodernism. My visual map in contemporary art and fashion photography includes artists like Nan Goldin, Cindy Sherman, Hellen van Meene, Rineke Dijkstra, Ed Templeton, Ryan McGinley, Anne Daems, Miwa Yanagi, Tracey Moffat, Catherine Opie, Tomoko Sawada, Vanessa Beecroft, Yasumasa Morimura, Collier Schorr among others.

Eco-Management and Audit Scheme (EMAS): An evaluation of success factors in the agricultural sector. The case of Italy's Emilia Romagna region.

Different tools have been used to set up and adopt the model for the fulfillment of the objective of this research. 1. The Model The base model that has been used is the Analytical Hierarchy Process (AHP) adapted with the aim to perform a Benefit Cost Analysis. The AHP developed by Thomas Saaty is a multicriteria decision - making technique which decomposes a complex problem into a hierarchy. It is used to derive ratio scales from both discreet and continuous paired comparisons in multilevel hierarchic structures. These comparisons may be taken from actual measurements or from a fundamental scale that reflects the relative strength of preferences and feelings. 2. Tools and methods 2.1. The Expert Choice Software The software Expert Choice is a tool that allows each operator to easily implement the AHP model in every stage of the problem. 2.2. Personal Interviews to the farms For this research, the farms of the region Emilia Romagna certified EMAS have been detected. Information has been given by EMAS center in Wien. Personal interviews have been carried out to each farm in order to have a complete and realistic judgment of each criteria of the hierarchy. 2.3. Questionnaire A supporting questionnaire has also been delivered and used for the interviews . 3. Elaboration of the data After data collection, the data elaboration has taken place. The software support Expert Choice has been used . 4. Results of the Analysis The result of the figures above (vedere altro documento) gives a series of numbers which are fractions of the unit. This has to be interpreted as the relative contribution of each element to the fulfillment of the relative objective. So calculating the Benefits/costs ratio for each alternative the following will be obtained: Alternative One: Implement EMAS Benefits ratio: 0, 877 Costs ratio: 0, 815 Benfit/Cost ratio: 0,877/0,815=1,08 Alternative Two: Not Implement EMAS Benefits ratio: 0,123 Costs ration: 0,185 Benefit/Cost ratio: 0,123/0,185=0,66 As stated above, the alternative with the highest ratio will be the best solution for the organization. This means that the research carried out and the model implemented suggests that EMAS adoption in the agricultural sector is the best alternative. It has to be noted that the ratio is 1,08 which is a relatively low positive value. This shows the fragility of this conclusion and suggests a careful exam of the benefits and costs for each farm before adopting the scheme. On the other part, the result needs to be taken in consideration by the policy makers in order to enhance their intervention regarding the scheme adoption on the agricultural sector. According to the AHP elaboration of judgments we have the following main considerations on Benefits: - Legal compliance seems to be the most important benefit for the agricultural sector since its rank is 0,471 - The next two most important benefits are Improved internal organization (ranking 0,230) followed by Competitive advantage (ranking 0, 221) mostly due to the sub-element Improved image (ranking 0,743) Finally, even though Incentives are not ranked among the most important elements, the financial ones seem to have been decisive on the decision making process. According to the AHP elaboration of judgments we have the following main considerations on Costs: - External costs seem to be largely more important than the internal ones (ranking 0, 857 over 0,143) suggesting that Emas costs over consultancy and verification remain the biggest obstacle. - The implementation of the EMS is the most challenging element regarding the internal costs (ranking 0,750).

La musa bambina. 1911-2011: un secolo di letteratura mitologica per ragazzi in Italia tra storia, educazione e narrazione

Questa ricerca mostra l’evoluzione della letteratura mitologica per ragazzi in Italia. Il primo libro italiano di mitologia per bambini è stato pubblicato nel 1911 (lo stesso anno di un’importante e violenta guerra coloniale tra l’Italia e la Libia): la scrittrice italiana Laura Orvieto pubblicò allora “Storie della storia del mondo”, in cui riunì antichi racconti greci per giovani lettori. Queste storie erano ispirate al libro mitologico per bambini “Il libro delle meraviglie” di Hawthorne (titolo originale “A Wonder Book for Girls and Boys”). In seguito molti scrittori italiani scrissero libri mitologici per giovani lettori: serie importanti di libri di mitologia per bambini furono pubblicate durante il regime mussoliniano – talvolta per diffondere l’ideologia fascista della superiorità romana. Durante questo periodo, i libri mitologici spesso mostravano uno stile letterario solenne. Dopo la seconda guerra mondiale, la letteratura mitologica per bambini cambiò lentamente prospettiva: gli scrittori italiani cominciarono ad usare il mito per parlare di problemi sociali (p.e. Gianni Rodari descriveva re Mida come un capitalista) e per spiegare le diverse condizioni umane (p.e. Beatrice Masini fa riferimento alle dee e alle eroine greche per descrivere la condizione femminile). La ricerca analizza anche la relazione tra mito e scuola in Italia: i racconti mitologici hanno sempre fatto parte dei programmi scolastici italiani per bambini dagli 8 agli 11 anni. Le riforme scolastiche – deliberate negli anni ’20 e ’40 – fissarono pratiche didattiche sui miti ancora oggi in uso. I racconti mitologici erano soprattutto un supporto per gli studi storici e letterari. Tuttavia, negli ultimi decenni, i miti sono divenuti un importante aiuto per gli insegnamenti scientifici e artistici.

Calibrazione di modelli idrologici con algoritmi multiobiettivo

Traditional procedures for rainfall-runoff model calibration are generally based on the fit of the individual values of simulated and observed hydrographs. It is used here an alternative option that is carried out by matching, in the optimisation process, a set of statistics of the river flow. Such approach has the additional, significant advantage to allow also a straightforward regional calibration of the model parameters, based on the regionalisation of the selected statistics. The minimisation of the set of objective functions is carried out by using the AMALGAM algorithm, leading to the identification of behavioural parameter sets. The procedure is applied to a set of river basins located in central Italy: the basins are treated alternatively as gauged and ungauged and, as a term of comparison, the results obtained with a traditional time-domain calibration is also presented. The results show that a suitable choice of the statistics to be optimised leads to interesting results in real world case studies as far as the reproduction of the different flow regimes is concerned.

Studio di metodi di preparazione e caratterizzazione di nanostrutture per la funzionalizzazione di materiali ceramici

This thesis was carried out in the context of a co-tutoring program between Centro Ceramico Bologna (Italy) and Instituto di Tecnologia Ceramica, Castellón de la Plana (Spain). The subject of the thesis is the synthesis of silver nanoparticles and at their likely decorative application in the productive process of porcelain ceramic tiles. Silver nanoparticles were chosen as a case study, because metal nanoparticles are thermally stable, and they have non-linear optical properties when nano-structured, and therefore they develop saturated colours. The nanoparticles were synthesized by chemical reduction in aqueous solution, a method chosen because of its reduced working steps and energy costs. Besides such a synthesis method uses non-expensive and non-toxic raw material. By adopting this synthesis technique, it was also possible to control the dimension and the final shape of the nanoparticles. Several syntheses were carried out during the research work, modifying the molecular weight of the reducing agent and/or the firing temperature, in order to evaluate the influence such parameters have on the Ag-nanoparticles formation. The syntheses were monitored with the use of UV-Vis spectroscopy and the average dimension as well as the morphology of the nanoparticles was analysed by SEM. From the spectroscopic data obtained from each synthesis, a kinetic study was completed, relating the progress of the reaction to the two variables (ie temperature and molecular weight of the reducing agent). The aim was finding equations that allow the establishing of a relationship between the operating conditions during the synthesis and the characteristics of the final product. The next step was finding the best method of synthesis for the decorative application. For such a purpose the amount of nanoparticles, their average particle size, the shape and the agglomeration are considered. An aqueous suspension containing the nanoparticles is then sprayed over the fired ceramic tiles and they are subsequently thermally treated in conditions similar to the industrial one. The colorimetric parameters of the obtained ceramic tiles were studied and the method proved successful, giving the ceramic tiles stable and intense colours.

Finite element models of coseismic deformation due to the 2009 L'Aquila (Italy) and 2008 Wenchuan(China) earthquakes

The topic of my Ph.D. thesis is the finite element modeling of coseismic deformation imaged by DInSAR and GPS data. I developed a method to calculate synthetic Green functions with finite element models (FEMs) and then use linear inversion methods to determine the slip distribution on the fault plane. The method is applied to the 2009 L’Aquila Earthquake (Italy) and to the 2008 Wenchuan earthquake (China). I focus on the influence of rheological features of the earth's crust by implementing seismic tomographic data and the influence of topography by implementing Digital Elevation Models (DEM) layers on the FEMs. Results for the L’Aquila earthquake highlight the non-negligible influence of the medium structure: homogeneous and heterogeneous models show discrepancies up to 20% in the fault slip distribution values. Furthermore, in the heterogeneous models a new area of slip appears above the hypocenter. Regarding the 2008 Wenchuan earthquake, the very steep topographic relief of Longmen Shan Range is implemented in my FE model. A large number of DEM layers corresponding to East China is used to achieve the complete coverage of the FE model. My objective was to explore the influence of the topography on the retrieved coseismic slip distribution. The inversion results reveals significant differences between the flat and topographic model. Thus, the flat models frequently adopted are inappropriate to represent the earth surface topographic features and especially in the case of the 2008 Wenchuan earthquake.

Sintesi di catalizzatori supportati su silice mesoporosa e loro utilizzo per l'idrodeclorurazione di molecole clorofluorurate

La necessità di raggiungere la sostenibilità ambientale delle produzioni industriali rappresenta un motore di sviluppo per innovative tecnologie impiantistiche e nuove filosofie produttive. Ad esempio, la necessità di promuovere lo smaltimento dei clorofluorocarburi, causa i loro dimostrati effetti dannosi sullo strato di ozono stratosferico, ha promosso lo sviluppo di nuovi processi industriali. In questo ambito ha acquisito sempre maggior importanza la reazione di idrodeclorurazione di clorofluorocarburi (CFC), in particolare rivolta alla produzione di idrocarburi fluorurati insaturi che mostrano caratteristiche interessanti per la produzione di polimeri con specifiche proprietà di resistenza meccanica, termica e chimica. In questo lavoro di tesi, svolto in collaborazione con SOLVAY SPECIALTY POLYMERS ITALY, sono stati studiati catalizzatori innovativi per la reazione di idrodeclorurazione del 1,2-dicloro-1,2,2-trifluoro-1-(triflurometossi)etano (AM) a 1,2,2-trifluoro-1-(trifluorometossi)etene (MVE).

Oltre il limite invalicabile. Procedure, piani, progetti sostenibili per le aree militari dismissibili di Piacenza

The research project concerns the restoration of military real estate, starting from the procedures in progress in Italy related to dismission, with particular emphasis for Piacenza and the case study of Caserme Bixio and Nicolai (Comparto Nord/San Sisto-Cittadella). The work is aimed at defining the relationship between urban planning and rehabilitation of dismissed military areas, in order to create a synergic effort capable to face the transformation of these sites and their integration into the urban tissue. The results obtained from the various recordings performed in Italy and in USA during the preparation of this thesis may help to find a new possible scenario for the Comparto Nord and its historic buildings.

Italia e Francia nell'Ungheria di Trianon (1919-1939): due modelli di penetrazione politico-culturale

Italy and France in Trianon’s Hungary: two political and cultural penetration models During the first post-war, the Danubian Europe was the theatre of an Italian-French diplomatic challenge to gain hegemony in that part of the continent. Because of his geographical position, Hungary had a decisive strategic importance for the ambitions of French and Italian foreign politics. Since in the 1920s culture and propaganda became the fourth dimension of international relations, Rome and Paris developed their diplomatic action in Hungary to affirm not only political and economic influence, but also cultural supremacy. In the 1930, after Hitler’s rise to power, the unstoppable comeback of German political influence in central-eastern Europe determined the progressive decline of Italian and French political and economic positions in Hungary: only the cultural field allowed a survey of Italian-Hungarian and French-Hungarian relations in the contest of a Europe dominated by Nazi Germany during the Second World War. Nevertheless, the radical geopolitical changes in second post-war Europe did not compromise Italian and French cultural presence in the new communist Hungary. Although cultural diplomacy is originally motivated by contingent political targets, it doesn’t respect the short time of politics, but it’s the only foreign politics tool that guarantees preservations of bilateral relations in the long run.

La nutrizione-idratazione artificiale è terapia? All'interfaccia tra scienza, diritto e bioetica, il fine vita in Italia, secondo una prospettiva di comunicazione della scienza post-accademica e Science&Technologies Studies (STS)

The question “artificial nutrition and hydration (ANH) is therapy or not?” is one of the key point of end-of-life issues in Italy, since it was (and it is also nowadays) a strategic and crucial point of the Italian Bioethics discussion about the last phases of human life: determining if ANH is therapy implies the possibility of being included in the list of treatments that could be mentioned for refusal within the living will document. But who is entitled to decide and judge if ANH is a therapy or not? Scientists? The Legislator? Judges? Patients? This issue at first sight seems just a matter of science, but at stake there is more than a scientific definition. According to several scholars, we are in the era of post-academic Science, in which Science broaden discussion, production, negotation and decision to other social groups that are not just the scientific communities. In this process, called co-production, on one hand scientific knowledge derives from the interaction between scientists and society at large. On the other hand, science is functional to co-production of social order. The continuous negotation on which science has to be used in social decisions is just the evidence of the mirroring negotation for different way to structure and interpret society. Thus, in the interaction between Science and Law, deciding what kind of Science could be suitable for a specific kind of Law, envisages a well defined idea of society behind this choice. I have analysed both the legislative path (still in progress) in the living will act production in Italy and Eluana Englaro’s judicial case (that somehow collapsed in the living will act negotiation), using official documents (hearings, texts of the official conference, committees comments and ruling texts) and interviewing key actors in the two processes from the science communication point of view (who talks in the name of science? Who defines what is a therapy? And how do they do?), finding support on the theoretical framework of the Science&Technologies Studies (S&TS).
