The country-of-origin is the “nationality” of a food when it goes through customs in a foreign country, and is a “brand” when the food is for sale in a foreign market. My research on country-of-origin labeling (COOL) started from a case study on the extra virgin olive oil exported from Italy to China; the result shows that asymmetric and imperfect origin information may lead to market inefficiency, even market failure in emerging countries. Then, I used the Delphi method to conduct qualitative and systematic research on COOL; the panel of experts in food labeling and food policy was composed of 19 members in 13 countries; the most important consensus is that multiple countries of origin marking can provide accurate information about the origin of a food produced by two or more countries, avoiding misinformation for consumers. Moreover, I enhanced the research on COOL by analyzing the rules of origin and drafting a guideline for the standardization of origin marking. Finally, from the perspective of information economics I estimated the potential effect of the multiple countries of origin labeling on the business models of international trade, and analyzed the regulatory options for mandatory or voluntary COOL of main ingredients. This research provides valuable insights for the formulation of COOL policy.

The subject of this doctoral dissertation concerns the definition of a new methodology for the morphological and morphometric study of fossilized human teeth, and therefore strives to provide a contribution to the reconstruction of human evolutionary history that proposes to extend to the different species of hominid fossils. Standardized investigative methodologies are lacking both regarding the orientation of teeth subject to study and in the analysis that can be carried out on these teeth once they are oriented. The opportunity to standardize a primary analysis methodology is furnished by the study of certain early Neanderthal and preneanderthal molars recovered in two caves in southern Italy [Grotta Taddeo (Taddeo Cave) and Grotta del Poggio (Poggio Cave), near Marina di Camerata, Campania]. To these we can add other molars of Neanderthal and modern man of the upper Paleolithic era, specifically scanned in the paleoanthropology laboratory of the University of Arkansas (Fayetteville, Arkansas, USA), in order to increase the paleoanthropological sample data and thereby make the final results of the analyses more significant. The new analysis methodology is rendered as follows: 1. Standardization of an orientation system for primary molars (superior and inferior), starting from a scan of a sample of 30 molars belonging to modern man (15 M1 inferior and 15 M1 superior), the definition of landmarks, the comparison of various systems and the choice of a system of orientation for each of the two dental typologies. 2. The definition of an analysis procedure that considers only the first 4 millimeters of the dental crown starting from the collar: 5 sections parallel to the plane according to which the tooth has been oriented are carried out, spaced 1 millimeter between them. The intention is to determine a method that allows for the differentiation of fossilized species even in the presence of worn teeth. 3. Results and Conclusions. The new approach to the study of teeth provides a considerable quantity of information that can better be evaluated by increasing the fossil sample data. It has been demonstrated to be a valid tool in evolutionary classification that has allowed (us) to differentiate the Neanderthal sample from that of modern man. In a particular sense the molars of Grotta Taddeo, which up until this point it has not been possible to determine with exactness their species of origin, through the present research they are classified as Neanderthal.

I Max Bill is an intense giornata of a big fresco. An analysis of the main social, artistic and cultural events throughout the twentieth century is needed in order to trace his career through his masterpieces and architectures. Some of the faces of this hypothetical mural painting are, among others, Le Corbusier, Walter Gropius, Ernesto Nathan Rogers, Kandinskij, Klee, Mondrian, Vatongerloo, Ignazio Silone, while the backcloth is given by artistic avant-gardes, Bauhaus, International Exhibitions, CIAM, war events, reconstruction, Milan Triennali, Venice Biennali, the School of Ulm. Architect, even though more known as painter, sculptor, designer and graphic artist, Max Bill attends the Bauhaus as a student in the years 1927-1929, and from this experience derives the main features of a rational, objective, constructive and non figurative art. His research is devoted to give his art a scientific methodology: each work proceeds from the analysis of a problem to the logical and always verifiable solution of the same problem. By means of composition elements (such as rhythm, seriality, theme and its variation, harmony and dissonance), he faces, with consistent results, themes apparently very distant from each other as the project for the H.f.G. or the design for a font. Mathematics are a constant reference frame as field of certainties, order, objectivity: ‘for Bill mathematics are never confined to a simple function: they represent a climate of spiritual certainties, and also the theme of non attempted in its purest state, objectivity of the sign and of the geometrical place, and at the same time restlessness of the infinity: Limited and Unlimited ’. In almost sixty years of activity, experiencing all artistic fields, Max Bill works, projects, designs, holds conferences and exhibitions in Europe, Asia and Americas, confronting himself with the most influencing personalities of the twentieth century. In such a vast scenery, the need to limit the investigation field combined with the necessity to address and analyse the unpublished and original aspect of Bill’s relations with Italy. The original contribution of the present research regards this particular ‘geographic delimitation’; in particular, beyond the deep cultural exchanges between Bill and a series of Milanese architects, most of all with Rogers, two main projects have been addressed: the realtà nuova at Milan Triennale in 1947, and the Contemporary Art Museum in Florence in 1980. It is important to note that these projects have not been previously investigated, and the former never appears in the sources either. These works, together with the most well-known ones, such as the projects for the VI and IX Triennale, and the Swiss pavilion for the Biennale, add important details to the reference frame of the relations which took place between Zurich and Milan. Most of the occasions for exchanges took part in between the Thirties and the Fifties, years during which Bill underwent a significant period of artistic growth. He meets the Swiss progressive architects and the Paris artists from the Abstraction-Création movement, enters the CIAM, collaborates with Le Corbusier to the third volume of his Complete Works, and in Milan he works and gets confronted with the events related to post-war reconstruction. In these years Bill defines his own working methodology, attaining an artistic maturity in his work. The present research investigates the mentioned time period, despite some necessary exceptions. II The official Max Bill bibliography is naturally wide, including spreading works along with ones more devoted to analytical investigation, mainly written in German and often translated into French and English (Max Bill himself published his works in three languages). Few works have been published in Italian and, excluding the catalogue of the Parma exhibition from 1977, they cannot be considered comprehensive. Many publications are exhibition catalogues, some of which include essays written by Max Bill himself, some others bring Bill’s comments in a educational-pedagogical approach, to accompany the observer towards a full understanding of the composition processes of his art works. Bill also left a great amount of theoretical speculations to encourage a critical reading of his works in the form of books edited or written by him, and essays published in ‘Werk’, magazine of the Swiss Werkbund, and other international reviews, among which Domus and Casabella. These three reviews have been important tools of analysis, since they include tracks of some of Max Bill’s architectural works. The architectural aspect is less investigated than the plastic and pictorial ones in all the main reference manuals on the subject: Benevolo, Tafuri and Dal Co, Frampton, Allenspach consider Max Bill as an artist proceeding in his work from Bauhaus in the Ulm experience . A first filing of his works was published in 2004 in the monographic issue of the Spanish magazine 2G, together with critical essays by Karin Gimmi, Stanislaus von Moos, Arthur Rüegg and Hans Frei, and in ‘Konkrete Architektur?’, again by Hans Frei. Moreover, the monographic essay on the Atelier Haus building by Arthur Rüegg from 1997, and the DPA 17 issue of the Catalonia Polytechnic with contributions of Carlos Martì, Bruno Reichlin and Ton Salvadò, the latter publication concentrating on a few Bill’s themes and architectures. An urge to studying and going in depth in Max Bill’s works was marked in 2008 by the centenary of his birth and by a recent rediscovery of Bill as initiator of the ‘minimalist’ tradition in Swiss architecture. Bill’s heirs are both very active in promoting exhibitions, researching and publishing. Jakob Bill, Max Bill’s son and painter himself, recently published a work on Bill’s experience in Bauhaus, and earlier on he had published an in-depth study on ‘Endless Ribbons’ sculptures. Angela Thomas Schmid, Bill’s wife and art historian, published in end 2008 the first volume of a biography on Max Bill and, together with the film maker Eric Schmid, produced a documentary film which was also presented at the last Locarno Film Festival. Both biography and documentary concentrate on Max Bill’s political involvement, from antifascism and 1968 protest movements to Bill experiences as Zurich Municipality councilman and member of the Swiss Confederation Parliament. In the present research, the bibliography includes also direct sources, such as interviews and original materials in the form of letters correspondence and graphic works together with related essays, kept in the max+binia+jakob bill stiftung archive in Zurich. III The results of the present research are organized into four main chapters, each of them subdivided into four parts. The first chapter concentrates on the research field, reasons, tools and methodologies employed, whereas the second one consists of a short biographical note organized by topics, introducing the subject of the research. The third chapter, which includes unpublished events, traces the historical and cultural frame with particular reference to the relations between Max Bill and the Italian scene, especially Milan and the architects Rogers and Baldessari around the Fifties, searching the themes and the keys for interpretation of Bill’s architectures and investigating the critical debate on the reviews and the plastic survey through sculpture. The fourth and last chapter examines four main architectures chosen on a geographical basis, all devoted to exhibition spaces, investigating Max Bill’s composition process related to the pictorial field. Paintings has surely been easier and faster to investigate and verify than the building field. A doctoral thesis discussed in Lausanne in 1977 investigating Max Bill’s plastic and pictorial works, provided a series of devices which were corrected and adapted for the definition of the interpretation grid for the composition structures of Bill’s main architectures. Four different tools are employed in the investigation of each work: a context analysis related to chapter three results; a specific theoretical essay by Max Bill briefly explaining his main theses, even though not directly linked to the very same work of art considered; the interpretation grid for the composition themes derived from a related pictorial work; the architecture drawing and digital three-dimensional model. The double analysis of the architectural and pictorial fields is functional to underlining the relation among the different elements of the composition process; the two fields, however, cannot be compared and they stay, in Max Bill’s works as in the present research, interdependent though self-sufficient. IV An important aspect of Max Bill production is self-referentiality: talking of Max Bill, also through Max Bill, as a need for coherence instead of a method limitation. Ernesto Nathan Rogers describes Bill as the last humanist, and his horizon is the known world but, as the ‘Concrete Art’ of which he is one of the main representatives, his production justifies itself: Max Bill not only found a method, but he autonomously re-wrote the ‘rules of the game’, derived timeless theoretical principles and verified them through a rich and interdisciplinary artistic production. The most recurrent words in the present research work are synthesis, unity, space and logic. These terms are part of Max Bill’s vocabulary and can be referred to his works. Similarly, graphic settings or analytical schemes in this research text referring to or commenting Bill’s architectural projects were drawn up keeping in mind the concise precision of his architectural design. As for Mies van der Rohe, it has been written that Max Bill took art to ‘zero degree’ reaching in this way a high complexity. His works are a synthesis of art: they conceptually encompass all previous and –considered their developments- most of contemporary pictures. Contents and message are generally explicitly declared in the title or in Bill’s essays on his artistic works and architectural projects: the beneficiary is invited to go through and re-build the process of synthesis generating the shape. In the course of the interview with the Milan artist Getulio Alviani, he tells how he would not write more than a page for an essay on Josef Albers: everything was already evident ‘on the surface’ and any additional sentence would be redundant. Two years after that interview, these pages attempt to decompose and single out the elements and processes connected with some of Max Bill’s works which, for their own origin, already contain all possible explanations and interpretations. The formal reduction in favour of contents maximization is, perhaps, Max Bill’s main lesson.

The research presented in my PhD thesis is part of a wider European project, FishPopTrace, focused on traceability of fish populations and products. My work was aimed at developing and analyzing novel genetic tools for a widely distributed marine fish species, the European hake (Merluccius merluccius), in order to investigate population genetic structure and explore potential applications to traceability scenarios. A total of 395 SNPs (Single Nucleotide Polymorphisms) were discovered from a massive collection of Expressed Sequence Tags, obtained by high-throughput sequencing, and validated on 19 geographic samples from Atlantic and Mediterranean. Genome-scan approaches were applied to identify polymorphisms on genes potentially under divergent selection (outlier SNPs), showing higher genetic differentiation among populations respect to the average observed across loci. Comparative analysis on population structure were carried out on putative neutral and outlier loci at wide (Atlantic and Mediterranean samples) and regional (samples within each basin) spatial scales, to disentangle the effects of demographic and adaptive evolutionary forces on European hake populations genetic structure. Results demonstrated the potential of outlier loci to unveil fine scale genetic structure, possibly identifying locally adapted populations, despite the weak signal showed from putative neutral SNPs. The application of outlier SNPs within the framework of fishery resources management was also explored. A minimum panel of SNP markers showing maximum discriminatory power was selected and applied to a traceability scenario aiming at identifying the basin (and hence the stock) of origin, Atlantic or Mediterranean, of individual fish. This case study illustrates how molecular analytical technologies have operational potential in real-world contexts, and more specifically, potential to support fisheries control and enforcement and fish and fish product traceability.

‘Who can be Greek?’ This was the question posed to the Greek society for the first time before the implementation of the Act 3838 in March 2010 which gave the right to access the Greek citizenship -under specific preconditions- to all children of legal migrants born or schooled in Greece. This change of the Nationality Code in order to include all those children was coincided by the economic crisis resulting into the rise of xenophobia, racism and extreme-right rhetoric. The outcome was the cancellation of the Act 3838 by the State Council in February 2013. Under this particular framework, the notions of identity and belonging formed among the youth of African background in Athens are explored. The ways those youngsters perceive not only themselves but also their peers, their countries of origin and the country they live in, are crucial elements of their self-identification. Researches have shown that the integration of the second generation is highly connected to their legal and social status. However, integration is a rather complex process, influenced and shaped by many variables and multiple factors. It is not linear; therefore, its outcomes are difficult to be predicted. Yet, I argue that citizenship acquisition facilitates the process as it transforms those children from ‘aliens’ to ‘citizens’. How these youngsters are perceived by the majority society and the State is one of the core questions of the research, focusing on the imposed dual ‘otherness’ they are subject to. On the one hand, they have to deal with the ‘otherness’ originating from the migrant status inherited to them by their parents, and on the other with the ‘otherness’ deriving from their different phenotypic characteristics. Race matters and becomes a means of discrimination against youth of African background who are perceived as inassimilable and ‘forever others’.

Logistics involves planning, managing, and organizing the flows of goods from the point of origin to the point of destination in order to meet some requirements. Logistics and transportation aspects are very important and represent a relevant costs for producing and shipping companies, but also for public administration and private citizens. The optimization of resources and the improvement in the organization of operations is crucial for all branches of logistics, from the operation management to the transportation. As we will have the chance to see in this work, optimization techniques, models, and algorithms represent important methods to solve the always new and more complex problems arising in different segments of logistics. Many operation management and transportation problems are related to the optimization class of problems called Vehicle Routing Problems (VRPs). In this work, we consider several real-world deterministic and stochastic problems that are included in the wide class of the VRPs, and we solve them by means of exact and heuristic methods. We treat three classes of real-world routing and logistics problems. We deal with one of the most important tactical problems that arises in the managing of the bike sharing systems, that is the Bike sharing Rebalancing Problem (BRP). We propose models and algorithms for real-world earthwork optimization problems. We describe the 3DP process and we highlight several optimization issues in 3DP. Among those, we define the problem related to the tool path definition in the 3DP process, the 3D Routing Problem (3DRP), which is a generalization of the arc routing problem. We present an ILP model and several heuristic algorithms to solve the 3DRP.

The thesis deals with the heterogenous category of the “unaccompanied minors”, concentrating the scientific work on those who migrate from Romania to the Italian city of Bologna. Between different migratory routes that include Romanian minors, I chose to explore the ones linked with the underground and illegal contexts. In order to analyse the reasons and the morphology of their migratory career, I used the multisituated field research which allowed me to consider the social policies in both the Romanian and the Italian environment. The main debate on the situation of the “unaccompanied children” refers to the extent to which these minors leave their country of origin “accompanied” by different adult figures and it also involves the role played by these adults. The first chapter is dedicated to a brief theoretical and methodological introduction to the main arguments of the thesis such as Romanian migration to Italy, trafficking in human beings, transnationality of migrant’s migration and decentered cooperation as a means of contrasting illegal migration and trafficking. Each field of research is characterized by a specific methodological approach, but they are all linked by the anthropological perspective I adopted throughout the entire work. The Romanian context, analized from a diachronic and a synchronic perspective represents the object of the second chapter. Some aspects of the Regime policies and other characteristics of the Romanian poscomunist period of “transition” are useful frameworks that become a background of the migration flows outside the country. The third chapter focuses on the Romanian patterns of migration. The reconstruction of some past attitudes that Romanians adopted towards migration are relevant in order to reveal the continuity with the present migratory practices. A consistent part is dedicated to a concrete example based on a field research in Bologna on a group of Romanian roma migrating from the south of Romania. The contact with these persons opened a debate on the limits between legal and illegal migration practices among the Romanians. The conclusion is that minors’ migration to Italy follows the adult patterns and flows. The nucleus of the field researches is included in the fourth and the fifth chapter. Before presenting the settings and the itineraries of the field researches, some deconstructive reflections are made on the representations that common sense and social sciences create on concepts as “child”, “minor” and “childhood”. A first perspective on the Romanian migrant minors emerges from a research concentrated on a group of roma teenagers engaged in Bologna in activities like windscreen washing, pocket-picking, begging and street prostitution. The aim of the research was to gain access to their daily life, to observe their relationship with the adults who “accompany” them and the strategies they activate in order to take some material profit out of their migratory experience. A parallel field research focuses on the Romanian minors who are part of the roma group coming from the south of Romania. Most of them are reunited with their family in Bologna, but according to the Italian law, they are all living as illegal migrants. Others are only temporary sheltered by these families and they meanwhile dedicate to illegal survviving practices. An interesting point of my participant observation was to reveal the motivations that these minors give when asked about the refusal to start a legal career inside the local Centres dedicated to the “non accompanied minors”. Their autoreflexivity brings some light on the controversy regarding the adequacy of the local and national care system and the migratory projects the minors have. In this respect, a small part of the research is dedicated to the phenomena of minors’ street prostitution in Bologna, as a useful contribution to the fragmented vision researchers have on the “unaccompanied” or “separated” children. The last chapter focuses on a decentered cooperation project that emerged as an alternative response the local administration from Bologna had chosen for facing the presence of numerous migrants coming from the south of Romania. The group of Romanian roma who was also the object of my field research became the starting point for the cooperation proposals between the city of Bologna and the city of Craiova. Although there are three projects involving the two administrations, throughout a period of stage in the Romanian city of Craiova I chose to analyse, only the one dedicated to the “urgent measures” requested in order to contrast the illegal migration and the trafficking in minors. This final part of the thesis highlightens the possible contribution that such a project might bring to the study of a complex and in some parts contradictory phenomena as that of the “unaccompanied” migrant minors.

Extensive literature outlined that the quality of the mother-foetus relationship is considered the main feature with regard to the quality of postnatal mother-infant interaction and also to the child’s psychical development. Nowadays the relationship between the pregnant woman and her foetus is viewed as the central factor of the somatic dialogue between the functioning of the maternal and the foetal organisms. This dialogue is responsible for the physic development of the child, as well as of its psychosomatic structure. Therefore the research area has necessarily had to extend to the analysis of psychological processes concerning: the pregnancy, the couple that is bound by parenthood, the influence of intergenerational dynamics. In fact, the formation of maternal identity, as well as that of the relationship between the woman and the foetus, refers to the pregnant woman’s relationship with her parents, especially with her mother. The same pregnancy, considered as a psychosomatic event, is directly influenced by relational, affective and social factors, particularly by the quality of the interiorized parental relations and the quality of the current relationships (such as that with her partner and with her family of origin). Some studies have begun to investigate the relationship between the pregnant woman and the foetus in term of “prenatal attachment” and its relationship with socio-demographic, psychological e psychopathological aspects (such as pre and post partum depression), but the research area is still largely unexplored. The present longitudinal research aimed to investigate the quality of the pregnant womanfoetus relationship by the prenatal attachment index, the quality of the interiorized relationship with woman’s parents, the level of alexithymic features and maternity social support, in relation with the modulation of the physiology of delivery and of postpartum, as well as of the physical development of the child. A consecutive sample of 62 Italian primipara women without any kind of pathologies, participated in the longitudinal study. In the first phase of this study (third trimester of the pregnancy), it has investigated the psychological processes connected to the affective investment of the pregnant women towards the unborn baby (by Prenatal Attachment Inventory), the mothers’ interiorized relationship with their own parents (by Parental Bonding Instrument), the social and affective support from their partner and their family of origin are able to supply (by Maternity Social Support Scale), and the level of alexithymia (by 20-Toronto Alexithymia Scale). In the second phase of this study, some data concerning the childbirth course carried out from a “deliverygram” (such as labour, induction durations and modalities of delivery) and data relative to the newborns state of well-being (such as Apgar and pH indexes). Finally, in the third phase of the study women have been telephoned a month after the childbirth. The semistructured interview investigated the following areas: the memory concerning the delivery, the return to home, the first interactions between the mother and the newborn, the breastfeeding, the biological rhythms achieved from newborns. From the data analysis a sample with a good level of prenatal attachment and of support social and a good capability to mental functioning emerged. An interesting result is that the most of the women have a great percentage of “affectionless control style” with both parents, but data is not sufficient to interpret this result. Moreover, considering the data relative to the delivery, medical and welfare procedures, that have been necessary, are coherent with the Italian mean, while the percentage of the caesarean section (12.9%) is inferior to the national percentage (30%). The 29% of vaginal partum has got epidural analgesia, which explains the high number (37%) of obstetrician operations (such as Kristeller). The data relative to the newborn (22 male, 40 female) indicates a good state of well-being because Apgar and pH indexes are superior to 7 at first and fifth minutes. Concerning the prenatal phase, correlation analysis showed that: the prenatal attachment scores positively correlated with the expected social support and negatively correlated with the “externally oriented thinking” dimension of alexithymia; the maternity social support negatively correlated with total alexithymia score, particularly with the “externally oriented thinking” dimension, and negatively correlated with maternal control of parental bonding. Concerning the delivery data, there are many correlations (after all obvious) among themselves. The most important are that the labour duration negatively correlated with the newborn’s index state of well-being. Finally, concerning the data from the postpartum phase the women’ assessments relative to the partum negatively correlated with the duration of the delivery and positively correlated with the assessment relative to the return to home and the interaction with the newborn. Moreover the length of permanence in the hospital negatively correlated with women’s assessments relative to the return to home that, in turn, positively correlated with the quality of breastfeeding, the interaction between the mother and the newborn and the biological regulation of the child. Finally, the women’ assessments relative to breastfeeding positively correlated with the mother-child interactions and the biological rhythms of children. From the correlation analysis between the variables of the prenatal phase and the data relative to the delivery, emerged that the prenatal attachment scores positively correlated with the dilatation stage scores and with the newborn’s Apgar index at first minute, the paternal care dimension of parental bonding positively correlated with the lengths of the various periods of childbirth like so the paternal control dimension with placental stage. Moreover, emerged that the expected social support positively correlated with the lengths of the various periods of childbirth and that the global alexithymia scores, particularly “difficulty to describe emotions” dimension, negatively correlated with total childbirth scores. From the correlation analysis between the variables of the prenatal phase and variable of the postpartum phase emerged that the total alexithymia scores positively correlated with the time elapsed from the childbirth to the breastfeeding of the child, the difficulty to describe emotions dimension of the alexithymia negatively correlated with the quality of the breastfeeding, the “externally oriented thinking” dimension of the alexithymia negatively correlated with mother-child interactions, and finally the paternal control dimension of the parental bonding negatively correlated with the time elapsed from the child to the breastfeeding of the child. Finally, from the analysis of the correlation between the data of the partum and the women’s assessments of the postpartum phase, emerged the negative correlation between the woman’s assessment relative to the delivery and the quantitative of obstetrician operations and the lengths of the various periods of childbirth, the positive correlation between the women’s assessment about the length of delivery periods and the real lengths of the same ones, the positive relation between woman’s assessment relative to the delivery and the Apgar index of children. In conclusion, there is a remarkable relation between the quality of the relationship the woman establishes with the foetus that influences the course of the pregnancy and the delivery that, in turn, influences the postpartum outcome, particularly relative to the mother-children relationship. Such data should be confirmed by heterogeneous populations in order to identify vulnerable women and to project focused intervention.

ABSTRACT: The dimension stone qualification through the use of non-destructive tests (NDT) is a relevant research topic for the industrial characterisation of finite products, because the competition of low-costs products can be sustained by an offer of highqualification and a top-guarantee products. The synthesis of potentialities offered by the NDT is the qualification and guarantee similar to the well known agro-industrial PDO, Protected Denomination of Origin. In fact it is possible to guarantee both, the origin and the quality of each stone product element, even through a Factory Production Control on line. A specific disciplinary is needed. A research developed at DICMA-Univ. Bologna in the frame of the “OSMATER” INTERREG project, allowed identifying good correlations between destructive and non-destructive tests for some types of materials from Verbano-Cusio-Ossola region. For example non conventional ultrasonic tests, image analysis parameters, water absorption and other measurements showed to be well correlated with the bending resistance, by relationships varying for each product. In conclusion it has been demonstrated that a nondestructive approach allows reaching several goals, among the most important: 1) the identification of materials; 2) the selection of products; 3) the substitution of DT by NDT. Now it is necessary to move from a research phase to the industrial implementation, as well as to develop new ND technologies focused on specific aims.

L’argomento affrontato nel presente lavoro di tesi dal titolo “Come tradurre il metadiscorso letterario. Esempi di scrittura femminile nell’Ottocento austriaco” è la versione interlinguistica di testi saggistici afferenti all’ambito del metadiscorso letterario. Nello specifico, non vengono analizzati testi di critica e/o metodologia ma scritti funzionali, di forte carattere pragmatico, che pur tuttavia rientrano tra le testimonianze di alta caratura letteraria, perché dovuti ad autrici che hanno fatto dell’espressione estetica la propria finalità primaria. I materiali scelti per l’analisi linguistico-testuale, compresi in un arco temporale tra la fine del Settecento e la metà dell’Ottocento, sono realizzati da donne che hanno operato in ambito teatrale facendo dell’attività di scrittura lo strumento della propria emancipazione intellettuale ed economica. La necessità di trovare una via alla pubblicazione le ha indotte a strategie di scrittura connotate da particolari stilemi e artifici retorici atti a favorire l’accettazione e la diffusione delle proposte editoriali di cui questi “paratesti” costituivano il momento giustificante. Il “lavoro di penna” è un’esperienza che viene ad assumere molteplici contorni, non privi di ricadute al momento della scelta delle strategie traduttive. Dal punto di vista formale, le testimonianze si collocano in una zona di modalità espressiva contigua alla testimonianza autobiografica. Il periodo storico e l’area di provenienza delle autrici hanno reso necessario un approccio capace di incrociare il piano diacronico con la dimensione diatopica, rendendo conto delle componenti diamesiche di una scrittura che nasce dal teatro per il teatro e ad esso e ai suoi frequentatori deve rapportarsi. Il modello traduttologico applicato ricava le sue linee fondamentali dalle riflessioni della linguistica testuale e dall’approccio integrato/multidisciplinare della “prototipologia dinamica”.

Until the end of the 1970s international migrants were perceived and analysed mainly within the frame of their lives in the host country, or as managing their lives and choices caught in a dilemma “between two cultures”. More recently, this approach has been challenged by an image of diasporic communities composed of individuals who “have collective homes away from home”. Migrants have become icons of hybridity and the metaphor of “border crossing”, the symbol of liberatory articulations between place, culture and identity. Migrants, it is also argued, have become transnational as they manage to live simultaneously in two countries. The research has the aim to study the migration process of the women who come from North Africa to Bologna. In particular, it investigates migrant women‘s relations with their adopted country and how their cultural practices are shaped by the transnational dimension of their lives. It was studied the journey of the migrant women’s lives across two countries and how their identities are going to change because of the experience of the migration. Migrant women are engaged in various kinds of practices and experiences through which they connect their country of origin and of residence. So this research focuses on the changes in the migrant women’s lives and the construction of their new identity. In particular, the research illustrates the development of a new notion of modernity, underlining how the migrant women construct a model of modernity that expresses a constant negotiation among diverse cultural models. The notion of modernity is not produced in opposition to tradition and religion, but is articulated with them in complex and diverse ways. The multiple ways in which migrant women understand modernity reflect their divergent identity’s renegotiation processes within the new society where they live.

The introduction of exotic species is one of the most important threats to biodiversity.This phenomenon may cause economic and environmental damage. To prevent these invasions there are institutions like EPPO. Nevertheless, the introduction of exotic pests is an increasing issue, difficult to control. Classic biological control, based on importation of natural enemies from the country of origin, has been successfully used for over 120 years, but it has also raised some criticism. My research work has focused on the study of the new associations occurring between indigenous parasitoids and three exotic pests introduced in Italy and Europe. The three target insects considered were: Cacyreus marshalli Butler (Lepidoptera: Lycaenidae), a pest of Geranium plants; Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), a plague of Castanea sp. and Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae). This ladybug has been introduced as a biological control agent, but since some years it considered as an invasive species. For C. marshalli I performed laboratory tests on acceptance and suitability of immature stages of this butterfly by Exorista larvarum (Diptera: Tachinidae) and Brachymeria tibialis (Hymenoptera: Chalcidicae). The experiments showed that these two parasitoids could be used to contain this pest. For D. kuriphilus I performed field samplings in an infested chestnut area, the samples were maintained in rearing chamber until gall wasp or parasitoids emergence. In the 3-year research many parasitoids of gall wasps were found; one of these, Torymus flavipes (Walker), was found in large number. For H. axyridis the research work included a first phase of field sampling, during which I searched indigenous parasitoids which had adapted to this new host; the only species found was Dinocampus coccinellae (Schrank) (Hymenoptera: Braconidae). Laboratory tests were performed on the wasp rearing, biology and capacity to contain H. axyridis.

Questa tesi di dottorato verte sull'individuazione di politiche industriali atte ad implementare il mercato dei prodotti a denominazione di origine. Inevitabilmente, l’analisi economica dei prodotti agroalimentari tipici di qualità implica anche l’approfondimento e l’individuazione, delle problematiche connesse con la creazione di un valore addizionale per il consumatore, rispetto a quello dei prodotti standardizzati. Questo approccio richiama l’attenzione, da una parte, sulle caratteristiche della domanda e sulla disponibilità del consumatore a riconoscere e apprezzare questo plus-valore, dall’altra sulle strategie che l’offerta può attivare per conseguire un premium price rispetto al prodotto standardizzato. Le certificazioni comunitarie Dop, Igp e Stg oltre che il marchio di prodotto biologico racchiudono, solitamente, tali dinamiche valoriali ma sono tutt’oggi poco conosciute dai consumatori. Diversi studi internazionali dimostrano, infatti, che la maggioranza dei cittadini comunitari ignorano il significato delle certificazioni di qualità. L’ipotesi di fondo di questo studio si basa sulla possibilità di fidelizzare questi marchi con i brand della grande distribuzione già affermati, come quello di Coop. Analizzare gli effetti dell’introduzione di prodotti private label a denominazione di origine nel mercato della grande distribuzione organizzata italiana ci permetterebbe di comprendere se questo segmento di mercato può aiutare il settore delle Dop/Igp. Questo studio ha cercato di verificare se il prodotto private label a denominazione di origine, riesca a sfruttare il doppio binario di fiducia rappresentato dal marchio comunitario unito a quello dell’impresa di distribuzione. Per comprendere la propensione del consumatore a spendere di più per questi prodotti, abbiamo utilizzato l’analisi dell’elasticità della domanda sul prezzo dei dati scanner fornitici da Coop Adriatica. Siamo riusciti a dimostrare tale positivo connubio confermato anche da una indagine demoscopica effettuata ad hoc sui consumatori.

Il settore suinicolo ricopre un ruolo rilevante nel contesto nazionale, con ricadute economiche e sociali di primaria importanza in varie regioni. Tuttavia da alcuni anni il settore si trova in crisi a causa dell’instabilità dei mercati internazionali, dello scarso coordinamento tra gli attori della filiera, della progressiva riduzione della redditività dei prodotti trasformati a Denominazione di Origine, della mancata valorizzazione dei tagli di carne fresca, nonché della difficoltà di aggredire i mercati esteri. Altre criticità riguardano la distribuzione del valore lungo la filiera e la scarsa efficacia delle politiche di coordinamento finora adottate. L'obiettivo della ricerca è quello di identificare gli elementi che possono garantire maggiore equilibrio di potere negoziale tra allevatori suinicoli e macellatori rispetto alla situazione attuale: verificati gli elementi critici che caratterizzano la relazione commerciale tra allevatori e macellatori, si avanzano alcune proposte operative utili al superamento delle fratture tra la componente agricola e quella dei macelli in Emilia Romagna. La struttura della tesi è la seguente: (capitolo 1) si descrive il quadro economico del settore suinicolo a livello internazionale e nazionale. Successivamente (capitolo 2) si passano in rassegna le teorie economiche utili a comprendere le ragioni alla base del malfunzionamento dei rapporti tra gli attori della filiera agroalimentare, mentre nel terzo capitolo è richiamato il quadro normativo comunitario, nazionale e regionale all’interno del quale tali relazioni si configurano. Nel quarto capitolo si elabora un modello interpretativo al fine di spiegare le fratture che oggi contraddistinguono le relazioni in essere tra gli attori della filiera: il “modello delle fratture”. Alla luce di questa concettualizzazione è stata svolta un’indagine diretta svolta presso gli operatori aderenti all’Organizzazione Interprofessionale del Gran Suino Italiano, i cui risultati hanno consentito di valutare l’efficacia del modello interpretativo e di fornire indicazioni migliorative della strategia di governance delle relazioni tra allevatori e macellatori.

Caratteristica comune ai regimi di consolidamento previsti dai diversi ordinamenti, è quella di consentire la compensazione tra utili e perdite di società residenti, e, di negare, o rendere particolarmente difficoltosa, la stessa compensazione, quando le perdite sono maturate da società non residenti. La non considerazione delle perdite comporta una tassazione al lordo del gruppo multinazionale, per mezzo della quale, non si colpisce il reddito effettivo dei soggetti che vi appartengono. L’effetto immediato è quello di disincentivare i gruppi a travalicare i confini nazionali. Ciò impedisce il funzionamento del Mercato unico, a scapito della libertà di stabilimento prevista dagli artt. 49-54 del TFUE. Le previsioni ivi contenute sono infatti dirette, oltre ad assicurare a società straniere il beneficio della disciplina dello Stato membro ospitante, a proibire altresì allo Stato di origine di ostacolare lo stabilimento in un altro Stato membro dei propri cittadini o delle società costituite conformemente alla propria legislazione. Gli Stati membri giustificano la discriminazione tra società residenti e non residenti alla luce della riserva di competenza tributaria ad essi riconosciuta dall’ordinamento europeo in materia delle imposte dirette, dunque, in base all’equilibrata ripartizione del potere impositivo. In assenza di qualsiasi riferimento normativo, va ascritto alla Corte di Giustizia il ruolo di interprete del diritto europeo. La Suprema Corte, con una serie di importanti pronunce, ha infatti sindacato la compatibilità con il diritto comunitario dei vari regimi interni che negano la compensazione transfrontaliera delle perdite. Nel verificare la compatibilità con il diritto comunitario di tali discipline, la Corte ha tentato di raggiungere un (difficile) equilibrio tra due interessi completamenti contrapposti: quello comunitario, riconducibile al rispetto della libertà di stabilimento, quello degli Stati membri, che rivendicano il diritto di esercitare il proprio potere impositivo.
