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.

Egemonia, socialismo e democrazia nell’occidente periferico. Gli studi gramsciani di Aricó e Portantiero tra Argentina e Messico.

La ricerca si propone di mostrare come il pensiero gramsciano sia stato riferimento prioritario di due intellettuali argentini in esilio in Messico dal 1976 al 1983: Juan Carlos Portantiero e José Maria Aricó. In quel periodo incentrarono le loro elaborazioni teorico-politiche sull’analisi della relazione tra Stato, società civile, democrazia e socialismo, partendo da una prospettiva gramsciana. Il fallimento della guerra di movimento in Argentina nei primi anni settanta li condusse a riflettere su strategie alternative di transizione al socialismo, il cui punto focale fu il concetto di "Egemonia". A partire dal 1975 indirizzarono la ripresa del pensiero di Gramsci alla creazione di un progetto politico adatto ad un contesto sempre più "occidentale", caratterizzato dalla presenza di una "società civile complessa", in cui risultava necessario combattere "guerre di posizione" e non "guerre di movimento". La prospettiva che connotò questo approccio alle riflessioni gramsciane rappresenta il culmine di un percorso che iniziarono negli anni ’50, quando sorsero i primi studi del pensiero gramsciano in Argentina. Sin da allora, Aricó e Portantiero si occuparono di Gramsci insieme al dirigente del PC argentino Agosti e continuarono a farlo anche durante gli anni sessanta e i primi anni settanta sulla rivista Pasado y Presente. Fu, però, nel periodo dell’esilio che ne ripresero il pensiero considerandolo nella sua totalità, a partire dagli scritti giovanili sino ai Quaderni del Carcere, rielaborandolo in maniera originale e costruendo una propria proposta di cammino verso socialismo nell' "occidente periferico" dell'Argentina, influenzati dall'azione del Partito Comunista Italiano.

Labour, LGBT* rights, and Europe. Discourses in Italy and Serbia

At the time of writing, all three elements that are evoked in the title – emancipation and social inclusion of sexual minorities, labour and labour activism, and the idea and substance of “Europe” – are being invested by deep, long-term, and – to varied degrees – radical processes of social transformation. The meaning of words like “equality”, “rights”, “inclusion”, and even “democracy” is as precarious and uncertain as are the lives of those European citizens who are marginalised by intersecting conditions of gender, sexuality, ethnicity, and class – in a constellation of precarities that is both unifying and fragmented (fragmenting). Conflicts are played, in hidden or explicit ways, over material processes of redistribution as well as discursive practices that revolve around these words. Against this backdrop, and roughly ten years after the European Union provided an input for institutional commitment to the protection of LGBT* workers' rights with the Council Directive 2000/78/EC, the dissertation contrasts discourses on workplace equality for LGBT* persons produced by a plurality of actors, seeking to identify values, semantics, and agendas framing and informing organisations’ views and showing how each actor has incorporated LGBT* rights into its own discourse, each time in a way that is functional to the construction and/or confirmation of its organisational identity: transnational union networks, by presenting LGBT* rights as a natural, neutral commitment within the framework of universal human rights protection; left-wing organisations, by collocating activism for LGBT* rights within a wider project of social emancipation that is for all the marginalised, yet is not neutral, but attached to specific values and opposed to specific political adversaries (the right-wing, the nationalists); business networks, by acknowledging diversity as a path to better performance and profits, thus encouraging inclusion and non-discrimination of “deserving” LGBT* workers.

Per di più la ricerca evidenzia la trasformazione politico-istituzionale e il processo di cambiamento dell’Albania dopo la caduta del muro di Berlino che segno la fine del sistema comunista, che vide l’Albania ad adottare il modello Italiano per il Capo dello Stato.

Physiology and Biotechnology of the Hydrogen Production with the Green Microalga Chlamydomonas reinhardtii

The hydrogen production in the green microalga Chlamydomonas reinhardtii was evaluated by means of a detailed physiological and biotechnological study. First, a wide screening of the hydrogen productivity was done on 22 strains of C. reinhardtii, most of which mutated at the level of the D1 protein. The screening revealed for the first time that mutations upon the D1 protein may result on an increased hydrogen production. Indeed, productions ranged between 0 and more than 500 mL hydrogen per liter of culture (Torzillo, Scoma et al., 2007a), the highest producer (L159I-N230Y) being up to 5 times more performant than the strain cc124 widely adopted in literature (Torzillo, Scoma, et al., 2007b). Improved productivities by D1 protein mutants were generally a result of high photosynthetic capabilities counteracted by high respiration rates. Optimization of culture conditions were addressed according to the results of the physiological study of selected strains. In a first step, the photobioreactor (PBR) was provided with a multiple-impeller stirring system designed, developed and tested by us, using the strain cc124. It was found that the impeller system was effectively able to induce regular and turbulent mixing, which led to improved photosynthetic yields by means of light/dark cycles. Moreover, improved mixing regime sustained higher respiration rates, compared to what obtained with the commonly used stir bar mixing system. As far as the results of the initial screening phase are considered, both these factors are relevant to the hydrogen production. Indeed, very high energy conversion efficiencies (light to hydrogen) were obtained with the impeller device, prooving that our PBR was a good tool to both improve and study photosynthetic processes (Giannelli, Scoma et al., 2009). In the second part of the optimization, an accurate analysis of all the positive features of the high performance strain L159I-N230Y pointed out, respect to the WT, it has: (1) a larger chlorophyll optical cross-section; (2) a higher electron transfer rate by PSII; (3) a higher respiration rate; (4) a higher efficiency of utilization of the hydrogenase; (5) a higher starch synthesis capability; (6) a higher per cell D1 protein amount; (7) a higher zeaxanthin synthesis capability (Torzillo, Scoma et al., 2009). These information were gathered with those obtained with the impeller mixing device to find out the best culture conditions to optimize productivity with strain L159I-N230Y. The main aim was to sustain as long as possible the direct PSII contribution, which leads to hydrogen production without net CO2 release. Finally, an outstanding maximum rate of 11.1 ± 1.0 mL/L/h was reached and maintained for 21.8 ± 7.7 hours, when the effective photochemical efficiency of PSII (ΔF/F'm) underwent a last drop to zero. If expressed in terms of chl (24.0 ± 2.2 µmoles/mg chl/h), these rates of production are 4 times higher than what reported in literature to date (Scoma et al., 2010a submitted). DCMU addition experiments confirmed the key role played by PSII in sustaining such rates. On the other hand, experiments carried out in similar conditions with the control strain cc124 showed an improved final productivity, but no constant PSII direct contribution. These results showed that, aside from fermentation processes, if proper conditions are supplied to selected strains, hydrogen production can be substantially enhanced by means of biophotolysis. A last study on the physiology of the process was carried out with the mutant IL. Although able to express and very efficiently utilize the hydrogenase enzyme, this strain was unable to produce hydrogen when sulfur deprived. However, in a specific set of experiments this goal was finally reached, pointing out that other than (1) a state 1-2 transition of the photosynthetic apparatus, (2) starch storage and (3) anaerobiosis establishment, a timely transition to the hydrogen production is also needed in sulfur deprivation to induce the process before energy reserves are driven towards other processes necessary for the survival of the cell. This information turned out to be crucial when moving outdoor for the hydrogen production in a tubular horizontal 50-liter PBR under sunlight radiation. First attempts with laboratory grown cultures showed that no hydrogen production under sulfur starvation can be induced if a previous adaptation of the culture is not pursued outdoor. Indeed, in these conditions the hydrogen production under direct sunlight radiation with C. reinhardtii was finally achieved for the first time in literature (Scoma et al., 2010b submitted). Experiments were also made to optimize productivity in outdoor conditions, with respect to the light dilution within the culture layers. Finally, a brief study of the anaerobic metabolism of C. reinhardtii during hydrogen oxidation has been carried out. This study represents a good integration to the understanding of the complex interplay of pathways that operate concomitantly in this microalga.

From fossil to sustainable diets: an assessment of farming energy footprint

The dependence of industrial agricolture on fossil fuels has been assessed in two comparative case studies between Italy (Emilia-Romagna and Piemonte)and Missouri. The first is related to dairy farming; 15 different farms were surveyed, divided into three different groups: grain based, pasture based and organic. The second is devoted to rice cropping; 12 holdings were examined divided into two groups: conventional and organic. Energy footprint was determined for structures, machinery, fertilizers, pesticides, fuel, electricity, feed and seeds. Possible scenarios of transition to a more sustainable agricolture based on renewable energy sources were analized in detail for all the farms analized.

Modelling and Uncertainty Quantification application to SA simulation codes in advanced SMR

In the framework of a global transition to a low-carbon energy mix, the interest in advanced nuclear Small Modular Reactors (SMRs) has been growing at the international level. Due to the high level of maturity reached by Severe Accident Codes for currently operating rectors, their applicability to advanced SMRs is starting to be studied. Within the present work of thesis and in the framework of a collaboration between ENEA, UNIBO and IRSN, an ASTEC code model of a generic IRIS reactor has been developed. The simulation of a DBA sequence involving the operation of all the passive safety systems of the generic IRIS has been carried out to investigate the code model capability in the prediction of the thermal-hydraulics characterizing an integral SMR adopting a passive mitigation strategy. The following simulation of 4 BDBAs sequences explores the applicability of Severe Accident Codes to advance SMRs in beyond-design and core-degradation conditions. The uncertainty affecting a code simulation can be estimated by using the method of Input Uncertainty Propagation, whose application has been realized through the RAVEN-ASTEC coupling and implementation on an HPC platform. This probabilistic methodology has been employed in a study of the uncertainty affecting the passive safety system operation in the DBA simulation of ASTEC, providing a further characterization of the thermal-hydraulics of this sequence. The application of the Uncertainty Quantification method to early core-melt phenomena has been investigated in the framework of a BEPU analysis of the ASTEC simulation of the QUENCH test-6 experiment. A possible solution to the encountered challenges has been proposed through the application of a Limit Surface search algorithm.

Transition Matters. Il ruolo del designer nella transizione sostenibile e circolare dei materiali polimerici

La ricerca indaga il ruolo del designer nella transizione sostenibile e circolare all’uso di materiali polimerici. Nel contesto contemporaneo la plastica è utilizzata in quasi ogni settore merceologico ma la sua futura applicazione è messa in forte discussione a causa dei visibili impatti ambientali del suo uso irresponsabile. Un passaggio netto dalla totale dipendenza alla liberazione dei polimeri è difficile; è necessario un periodo di transizione che permetta di coesistere responsabilmente con i polimeri in attesa di trovare dei validi sostituti. L’obiettivo della ricerca è lavorare su questo periodo ponendo il designer e le sue competenze come soggetti chiave del movimento. La tesi di ricerca propone un approccio per calare le pratiche del Transition Design nella progettazione di sistemi-prodotto, nutrendosi degli attributi anticipatori dell’Advanced Design e puntando agli obiettivi del Circular Design, lavorando a partire dalle merci più critiche nel contesto contemporaneo: quelle in polimero fossile non riciclabile. Contributo della tesi è la figura del Transition Matter Designer, un progettista di transizioni dei materiali che prevede metamorfosi di sistemi-prodotto nel tempo grazie alle sue competenze a diverse scale del progetto: forma l’utente agli atteggiamenti circolari e sostenibili, caratterizza i materiali per individuarne nuovi usi, seleziona i processi produttivi adatti a prevenire scarti e ne anticipa i cicli di vita nei prodotti. I Knitted Fasteners sono il risultato della simulazione del lavoro del Transition Matter Designer nel tessile: un sistema di elementi di fissaggio, personalizzabili dallo stilista e integrati negli abiti a maglia, che permettono di eliminare l’uso di fashion fasteners in plastica e metallo, elementi che rendono difficile il riciclo dei capi. Dalla sperimentazione è emerso il modello concettuale della Transindustrial Production: un lavoro di collaborazione fra Transition Matter Designer e creativo per dare identità ai materiali polimerici circolari attraverso l’ibridazione fra artigianato e industria, tipico del Made in Italy.
