Politiche di sviluppo e questione etnica. La cooperazione italiana IN Bosnia Erzegovina

The globalization process of the last twenty years has changed the world through international flows of people, policies and practices. International cooperation to development is a part of that process and brought International Organizations (IOs) and Non Governmental Organizations (NGOs) from the West to the rest of the world. In my thesis I analyze the Italian NGOs that worked in Bosnia Herzegovina (BH) to understand which development projects they realized and how they faced the ethnic issue that characterized BH. I consider the relation shaped between Italian NGOs and Bosnian civil society as an object of ethnic interests. In BH, once part of former Yugoslavia, the transition from the communist regime to a democratic country has not been completed. BH’s social conditions are characterized by strong ethnic divisions. The legacy of the early 1990s crisis was a phenomenon of ethnic identities created before the war and that still endure today. The Dayton Peace Agreement signed in 1995 granted the peace and reinforced the inter-ethnic hate between the newly recognized three principal ethnicities: Serbs, Croats and Bosniak. Through the new constitution, the institutions were characterized by division at every level, from the top to the bottom of society. Besides it was the first constitution ever written and signed outside the own country; that was the root of the state of exception that characterized BH. Thus ethnic identities culture survived through the international political involvement. At the same time ethnic groups that dominated the political debate clashed with the international organization’s democratic purpose to build a multicultural and democratic state. Ethnic and also religious differences were the instruments for a national statement that might cause the transition and development projects failure. Fifteen years later social fragmentation was still present and it established an atmosphere of daily cultural violence. Civil society suffered this condition and attended to recreate the ethnic fragmentation in every day life. Some cities became physically divided and other cities don’t tolerated the minority presence. In rural areas, the division was more explicit, from village to village, without integration. In my speech, the anthropology for development – the derivative study from applied anthropology – constitutes the point of view that I used to understand how ethnic identities still influenced the development process in BH. I done ethnographic research about the Italian cooperation for development projects that were working there in 2007. The target of research were the Italian NGOs that created a relation with Bosnian civil society; they were almost twenty divided in four main field of competences: institutional building, education, agriculture and democratization. I assumed that NGOs work needed a deep study because the bottom of society is the place where people could really change their representation and behavior. Italian NGOs operated in BH with the aim of creating sustainable development. They found cultural barricade that both institutions and civil society erected when development projects have been applied. Ethnic and religious differences were stressed to maintain boundaries and fragmented power. Thus NGOs tried to negotiate development projects by social integration. I found that NGOs worked among ethnic groups by pursuing a new integration. They often gained success among people; civil society was ready to accept development projects and overcome differences. On the other hand NGOs have been limited by political level that sustained the ethnic talk and by their representation of Bosnian issue. Thus development policies have been impeded by ethnic issue and by cooperation practices established on a top down perspective. Paradoxically, since international community has approved the political ethnic division within DPA, then the willing of development followed by funding NGOs cooperation projects was not completely successful.

Identificazione di un QTL principale per resistenza a ruggine bruna sul cromosoma 7B di frumento duro

Leaf rust caused by Puccinia triticina is a serious disease of durum wheat (Triticum durum) worldwide. However, genetic and molecular mapping studies aimed at characterizing leaf rust resistance genes in durum wheat have been only recently undertaken. The Italian durum wheat cv. Creso shows a high level of resistance to P. triticina that has been considered durable and that appears to be due to a combination of a single dominant gene and one or more additional factors conferring partial resistance. In this study, the genetic basis of leaf rust resistance carried by Creso was investigated using 176 recombinant inbred lines (RILs) from the cross between the cv. Colosseo (C, leaf rust resistance donor) and Lloyd (L, susceptible parent). Colosseo is a cv. directly related to Creso with the leaf rust resistance phenotype inherited from Creso, and was considered as resistance donor because of its better adaptation to local (Emilia Romagna, Italy) cultivation environment. RILs have been artificially inoculated with a mixture of 16 Italian P. triticina isolates that were characterized for virulence to seedlings of 22 common wheat cv. Thatcher isolines each carrying a different leaf rust resistance gene, and for molecular genotypes at 15 simple sequence repeat (SSR) loci, in order to determine their specialization with regard to the host species. The characterization of the leaf rust isolates was conducted at the Cereal Disease Laboratory of the University of Minnesota (St. Paul, USA) (Chapter 2). A genetic linkage map was constructed using segregation data from the population of 176 RILs from the cross CL. A total of 662 loci, including 162 simple sequence repeats (SSRs) and 500 Diversity Arrays Technology markers (DArTs), were analyzed by means of the package EasyMap 0.1. The integrated SSR-DArT linkage map consisted of 554 loci (162 SSR and 392 DArT markers) grouped into 19 linkage blocks with an average marker density of 5.7 cM/marker. The final map spanned a total of 2022 cM, which correspond to a tetraploid genome (AABB) coverage of ca. 77% (Chapter 3). The RIL population was phenotyped for their resistance to leaf rust under artificial inoculation in 2006; the percentage of infected leaf area (LRS, leaf rust susceptibility) was evaluated at three stages through the disease developmental cycle and the area under disease progress curve (AUDPC) was then calculated. The response at the seedling stage (infection type, IT) was also investigated. QTL analysis was carried out by means of the Composite Interval Mapping method based on a selection of markers from the CL map. A major QTL (QLr.ubo-7B.2) for leaf rust resistance controlling both the seedling and the adult plant response, was mapped on the distal region of chromosome arm 7BL (deletion bin 7BL10-0.78-1.00), in a gene-dense region known to carry several genes/QTLs for resistance to rusts and other major cereal fungal diseases in wheat and barley. QLr.ubo-7B.2 was identified within a supporting interval of ca. 5 cM tightly associated with three SSR markers (Xbarc340.2, Xgwm146 e Xgwm344.2), and showed an R2 and an LOD peak value for the AUDPC equal to 72.9% an 44.5, respectively. Three additional minor QTLs were also detected (QLr.ubo-7B.1 on chr. 7BS; QLr.ubo-2A on chr. 2AL and QLr.ubo-3A on chr. 3AS) (Chapter 4). The presence of the major QTL (QLr.ubo-7B.2) was validated by a linkage disequilibrium (LD)-based test using field data from two different plant materials: i) a set of 62 advanced lines from multiple crosses involving Creso and his directly related resistance derivates Colosseo and Plinio, and ii) a panel of 164 elite durum wheat accessions representative of the major durum breeding program of the Mediterranean basin. Lines and accessions were phenotyped for leaf rust resistance under artificial inoculation in two different field trials carried out at Argelato (BO, Italy) in 2006 and 2007; the durum elite accessions were also evaluated in two additional field experiments in Obregon (Messico; 2007 and 2008) and in a green-house experiment (seedling resistance) at the Cereal Disease Laboratory (St. Paul, USA, 2008). The molecular characterization involved 14 SSR markers mapping on the 7BL chromosome region found to harbour the major QTL. Association analysis was then performed with a mixed-linear-model approach. Results confirmed the presence of a major QTL for leaf rust resistance, both at adult plant and at seedling stage, located between markers Xbarc340.2, Xgwm146 and Xgwm344.2, in an interval that coincides with the supporting interval (LOD-2) of QLr.ubo-7B.2 as resulted from the RIL QTL analysis. (Chapter 5). The identification and mapping of the major QTL associated to the durable leaf rust resistance carried by Creso, together with the identification of the associated SSR markers, will enhance the selection efficiency in durum wheat breeding programs (MAS, Marker Assisted Selection) and will accelerate the release of cvs. with durable resistance through marker-assisted pyramiding of the tagged resistance genes/QTLs most effective against wheat fungal pathogens.

Studio della maturazione di formaggi pecorino stagionati in stabilimento e in grotta

Aims: Ripening evaluation of two different Pecorino cheese varieties ripened according either to a traditional method in plant and in cave. Different ripening features have been analyzed in order to evaluate the cave as possible ripening environment with the aim of obtaining a peculiar product which could also establish an added value to the cultural heritage of the local place in which it has been originally manufactured. Methods and Results: Chemical-physical features of Pecorino cheese have been initially analyzed into two different ripening environments and experimentations, among which: pH, weight reduction and subsequent water activity. Furthermore, the microbial composition has been characterized in relationship with the two different ripening environments, undertaking a variety of microbial groups, such as: lactic bacteria, staphylococci, yeasts, lactococci, enterobacteria, enterococci. Besides, an additional analysis for the in-cave adaptability evaluation has been the identification of biogenic amines inside the Pecorino cheese (2-phenilethylamine, putrescine, cadaverine, hystidine, tyramine, spermine and spermidine). Further analysis were undertaken in order to track the lipid profile evolution, reporting the concentration of the cheese free fatty acids in object, in relation with ripening time, environment and production. In order to analyse the flavour compounds present in Pecorino cheese, the SPME-GC-MS technique has been widely employed. As a result, it is confirmed the trend showed by the short-chain free fatty acids, that is to say the fatty acids which are mostly involved in conveying a stronger flavor to the cheese. With the purpose of assessing the protheolytic patterns of the above-mentioned Pecorino cheese in the two different ripening environments and testing methods, the technique SDS-PAGE has been employed into the cheese insoluble fraction, whereas the SDS-PAGE technique has been carried out into the cheese soluble portion. Furthermore, different isolated belonging to various microbial groups have been genotypically characterized though the ITS-PCR technique with the aim to identify the membership species. With reference to lactic bacillus the characterized species are: Lactobacillus brevis, Lactobacillus curvatus and Lactobacillus paraplantarum. With reference to lactococci the predominant species is Lactococcus lactis, coming from the employed starter used in the cheese manufacturing. With reference to enterococcus, the predominant species are Enterococcus faecium and Enterococcus faecalis. Moreover, Streptococcus termophilus and Streptococcus macedonicus have been identified too. For staphylococci the identified species are Staphyilococcus equorum, Staphylococcus saprophyfiticus and Staphylococcus xylosus. Finally, a sensorial analysis has been undertaken through on one side a consumer test made by inexperienced consumers, and on the other side through a panel test achieved by expert consumers. From such test Pecorino cheese ripened in cave were found to be more pleasant in comparison with Pecorino cheese ripened in plant. Conclusions: The proposed approach and the undertaken analysis showed the cave as preferential ripening environment for Pecorino cheese and for the development of a more palatable product and safer for consumers’ health.

Fenomeni di diffusione delle notizie in siti di microblogging: modelli di analisi e studio di caso.

L'informazione è alla base della conoscenza umana. Senza, non si potrebbe sapere nulla di ciò che esiste, di ciò che è stato o di quello che potrebbe accadere. Ogni giorno si assimilano moltissime informazioni, che vengono registrate nella propria memoria per essere riutilizzate all'occorrenza. Ne esistono di vari generi, ma il loro insieme va a formare quella che è la cultura, educazione, tradizione e storia dell'individuo. Per questo motivo è importante la loro diffusione e salvaguardia, impedendone la perdita che costerebbe la dipartita di una parte di sé, del proprio passato o del proprio futuro. Al giorno d'oggi le informazioni possono essere acquisite tramite persone, libri, riviste, giornali, la televisione, il Web. I canali di trasmissione sono molti, alcuni più efficaci di altri. Tra questi, internet è diventato un potente strumento di comunicazione, il quale consente l'interazione tra chi naviga nel Web (ossia gli utenti) e una partecipazione attiva alla diffusione di informazioni. Nello specifico, esistono siti (chiamati di microblogging) in cui sono gli stessi utenti a decidere se un'informazione possa essere o meno inserita nella propria pagina personale. In questo caso, si è di fronte a una nuova "gestione dell'informazione", che può variare da utente a utente e può defluire in catene di propagazione (percorsi che compiono i dati e le notizie tra i navigatori del Web) dai risvolti spesso incerti. Ma esiste un modello che possa spiegare l'avanzata delle informazioni tra gli utenti? Se fosse possibile capirne la dinamica, si potrebbe venire a conoscenza di quali sono le informazioni più soggette a propagazione, gli utenti che più ne influenzano i percorsi, quante persone ne vengono a conoscenza o il tempo per cui resta attiva un'informazione, descrivendone una sorta di ciclo di vita. E' possibile nel mondo reale trovare delle caratteristiche ricorrenti in queste propagazioni, in modo da poter sviluppare un metodo universale per acquisirne e analizzarne le dinamiche? I siti di microblogging non seguono regole precise, perciò si va incontro a un insieme apparentemente casuale di informazioni che necessitano una chiave di lettura. Quest'ultima è proprio quella che si è cercata, con la speranza di poter sfruttare i risultati ottenuti nell'ipotesi di una futura gestione dell'informazione più consapevole. L'obiettivo della tesi è quello di identificare un modello che mostri con chiarezza quali sono i passaggi da affrontare nella ricerca di una logica di fondo nella gestione delle informazioni in rete.

"Narrativa di frontiera". Fenomenologia di una forma aperta.

«Fiction of frontier». Phenomenology of an open form/voice. Francesco Giustini’s PhD dissertation fits into a genre of research usually neglected by the literary criticism which nevertheless is arousing much interest in recent years: the relationship between Literature and Space. In this context, the specific issue of his work consists in the category of the Frontier including its several implications for the XX century fiction. The preliminary step, at the beginning of the first section of the dissertation, is a semantic analysis: with precision, Giustini describes the meaning of the word “frontier” here declined in a multiplicity of cultural, political and geographical contexts, starting from the American frontier of the pioneers who headed for the West, to the exotic frontiers of the world, with whose the imperialistic colonization has come into contact; from the semi-uninhabited areas like deserts, highlands and virgin forests, to the ethnic frontiers between Indian and white people in South America, since the internal frontiers of the Countries like those ones between the District and the Capital City, the Centre and the Outskirts. In the next step, Giustini wants to focus on a real “ myth of the frontier”, able to nourish cultural and literary imagination. Indeed, the literature has told and chosen the frontier as the scenery for many stories; especially in the 20th Century it made the frontier a problematic space in the light of events and changes that have transformed the perception of space and our relationship with it. Therefore, the dissertation proposes a critical category, it traces the hallmarks of a specific literary phenomenon defined “ Fiction of the frontier” ,present in many literary traditions during the 20th Century. The term “Fiction” (not “Literature” or “Poetics”) does not define a genre but rather a “procedure”, focusing on a constant issue pointed out from the texts examined in this work : the strong call to the act of narration and to its oral traditions. The “Fiction of the Frontier” is perceived as an approach to the world, a way of watching and feeling the objects, an emotion that is lived and told through the story- a story where the narrator ,through his body and his voice, takes the rule of the witness. The following parts, that have an analytic style, are constructed on the basis of this theoretical and methodological reflection. The second section gives a wide range of examples into we can find the figure and the myth of the frontier through the textual analysis which range over several literary traditions. Starting from monographic chapters (Garcia Marquez, Callado, McCarthy), to the comparative reading of couples of texts (Calvino and Verga Llosa, Buzzati and Coetzee, Arguedas and Rulfo). The selection of texts is introduced so as to underline a particular aspect or a form of the frontier at every reading. This section is articulated into thematic voices which recall some actions that can be taken into the ambiguous and liminal space of the frontier (to communicate, to wait, to “trans-culturate”, to imagine, to live in, to not-live in). In this phenomenology, the frontier comes to the light as a physical and concrete element or as a cultural, imaginary, linguistic, ethnic and existential category. In the end, the third section is centered on a more defined and elaborated analysis of two authors, considered as fundamental for the comprehension of the “Fiction of the frontier”: Joseph Conrad and João Guimarães Rosa. Even if they are very different, being part of unlike literary traditions, these two authors show many connections which are pointed by the comparative analysis. Maybe Conrad is the first author that understand the feeling of the frontier , freeing himself from the adventure romance and from the exotic nineteenthcentury tradition. João Guimarães Rosa, in his turn, is the great narrator of Brazilian and South American frontier, he is the man of sertão and of endless spaces of the Centre of Brazil. His production is strongly linked to that one belonged to the author of Heart of Darkness.

Dimensionamento di invasi per il controllo dei deflussi nei bacini urbanizzati

Urbanization is a continuing phenomenon in all the world. Grasslands, forests, etc. are being continually changed to residential, commercial and industrial complexes, roads and streets, and so on. One of the side effects of urbanization with which engineers and planners must deal with, is the increase of peak flows and volumes of runoff from rainfall events. As a result, the urban drainage and flood control systems must be designed to accommodate the peak flows from a variety of storms that may occur. Usually the peak flow, after development, is required not to exceed what would have occurred from the same storm under conditions existing prior to development. In order to do this it is necessary to design detention storage to hold back runoff and to release it downstream at controlled rates. In the first part of the work have been developed various simplified formulations that can be adopted for the design of stormwater detention facilities. In order to obtain a simplified hydrograph were adopted two approaches: the kinematic routing technique and the linear reservoir schematization. For the two approaches have been also obtained other two formulations depending if the IDF (intensity-duration-frequency) curve is described with two or three parameters. Other formulations have been developed taking into account if the outlet have a constant discharge or it depends on the water level in the pond. All these formulations can be easily applied when are known the characteristics of the drainage system and maximum discharge that these is in the outlet and has been defined a Return Period which characterize the IDF curve. In this way the volume of the detention pond can be calculated. In the second part of the work have been analyzed the design of detention ponds adopting continuous simulation models. The drainage systems adopted for the simulations, performed with SWMM5, are fictitious systems characterized by different sizes, and different shapes of the catchments and with a rainfall historical time series of 16 years recorded in Bologna. This approach suffers from the fact that continuous record of rainfall is often not available and when it is, the cost of such modelling can be very expensive, and that the majority of design practitioners are not prepared to use continuous long term modelling in the design of stormwater detention facilities. In the third part of the work have been analyzed statistical and stochastic methodologies in order to define the volume of the detention pond. In particular have been adopted the results of the long term simulation, performed with SWMM, to obtain the data to apply statistic and stochastic formulation. All these methodologies have been compared and correction coefficient have been proposed on the basis of the statistic and stochastic form. In this way engineers which have to design a detention pond can apply a simplified procedure appropriately corrected with the proposed coefficient.

Pasta secca e identità nazionale. Note di storia dell'alimentazione

In the wide range of data that the nutrition subject offers to the historical observation, this investigation focuses on one of the functions that food serves in the social context: that is, to signify cultural identity. In this context, we will analyse the ways in which industrially produced pasta has come to its status as one of the symbolic forms of twentieth-century Italian food, contributing to a sense of social identity that forms part of the process of nation-building developed during the XX century. The nature of the relationship between pasta and Italian food is analysed for a period of almost a century (1886-1984) through a variety of different sources: government enquiries, cookery books, gastronomic guides and menus of official dinners. The assemblage of such documents in one study allows investigation of certain themes throughout a wide range of gastronomical cultures active within the national borders. In this way, links are made between the production, adoption, reception and dissemination of the ingredients and Italian Unification.This method has made it possible to restore one possible form of historical knowledge of twentieth-century gastronomy and of the experiences by which it was influenced.
