Full textAbstract:
The basic aim of this thesis is to describe and analyse how �the woman voter� was constructed within Labor discourse during the Hawke/Keating years. My domain of investigation is electoral politics, in particular the federal election campaigns of 1983 and 1993. These elections flank the beginning and the end of the Labor decade, a period of great significance to both the development of Labor politics specifically and Australian politics in general. The elections of 1983 and 1993 were campaigns in which the Party made a concerted effort to attract women�s votes. Through a reading of the various texts associated with these two campaigns, I explore the construction of �the woman voter� as a �new� political subject position within Labor discourse. The dominant influences on the construction of �the woman voter� as a new subject position were Labor discourse and feminism, or more precisely Labor discourse affected by the incursion of feminism from the 1970s onwards. This thesis describes and analyses how this subject position has been produced and reproduced within Labor discourse. The gender gap research developed for the 1983 federal election constitutes one of the more important technologies that work to construct �the woman voter� within Labor discourse. A reading of the texts associated with the 1983 campaign reveals the character of �the woman voter� as a caring figure. However, as the Labor decade progressed, �the woman voter� is articulated in Labor discourse as a more complex figure, focused on her responsibilities both in the home and at paid work. A reading of various texts associated with the 1993 election campaign shows that �the woman voter� is constructed as a carer-worker; this subject position is broadly consonant with the objectives liberal, economic government. Certain modifications within this basic subject position can be observed in Labor�s anti-GST campaign materials, which made an appeal to the woman voter as consumer.

Utifrån mina resultat kan jag konstatera att validiteten i ALP 2 och ALP 3 är relativt låg. Jag anser att ALP-testet är ett material vilket jag inte kan ha en direkt praktisk nytta av i min undervisning. Däremot är materialet väl värt att revidera och på så sätt öka dess validitet.</p>

The present manuscript is a brief, self--contained study of the ALP solution to the Strong CP problem of QCD.
The Standard Model is embedded with an ALP via an Effective Field Theory truncated at the lowest
non--renormalizable order in the Laurent expansion. The field content and the symmetry group are minimally
extended adding a single pseudo--scalar light resonance to the Standard Model, that is the Goldstone boson of an
anomalous global $U(1)_\mathrm{PQ}$ symmetry spontaneously broken at some high energy scale $f_a.$
The Effective Field Theory is then evolved along its Renormalization Group flow from this Ultra--Violet scale down
to the perturbative limit of QCD. Some attention is dedicated to the non--perturbative regime of Strong Interactions
with the QCD--Chiral Lagrangian.
Weak annihilation-induced ALP emissions generated by flavor conserving couplings and weak mesonic decays
induced by flavor violating ALP couplings are studied in the framework of a single experimental signature.
This allows to extract important bounds and correlation information on the low--energy ALP--fermion couplings
from flavor factories data. ALP--leptonic final state decays are also studied, a correction on the massless ALP limit
and the full mass dependence of the decay width is recovered. This opens up the study for a plethora of signals able
to project limits onto ALP--leptons and ALP--quarks parameters.<br>The present manuscript is a brief, self--contained study of the ALP solution to the Strong CP problem of QCD.

Previous issue date: 2016-05-31<br>CAPES<br>CNPq<br>O significado da calça jeans produzida por Toritama é uma construção coletiva, fruto de ações
conjuntas de uma cadeia de atores os quais empreendem culturalmente ao articularem
significados a esse artefato. Assim, para contextualizar essa dinâmica de significação,
buscamos compreender as dimensões discursivas que demarcam a produção cultural da calça
jeans no campo da moda em Toritama, a partir da perspectiva de cadeia de atores que atuam
como produtores culturais. Diante desse cenário, o estudo segue na perspectiva teóricometodológico
sugerida pelo Circuito da Cultura de Du Gay et al. (1997a), oriundos da
tradição dos Estudos Culturais. Como forma de acessar o campo das subjetividades da
produção da calça jeans na cidade de Toritama, foram realizadas entrevistas semi-estruturadas
com 06 atores representativos da cadeia produtiva, os quais impulsionam e demarcam a
produção subjetiva da calça jeans como produto de moda. A análise dos dados foi norteada
com o suporte da - Análise do Discurso (AD) -, na perspectiva proposta por Gil (2002). As
considerações sobre os achados de pesquisa apontam para uma produção cultural que
significa não só a calça jeans de Toritama no campo da moda, mas todo o modo de vida e os
valores culturais dessa cidade. Logo, diante dos argumentos, dos achados de pesquisa, as
considerações finais sugerem que a moda, em Toritama, por meio da calça jeans, surge como
um emaranhado de discursos culturais e disputas por poder. Os quais minimamente relevam
estratégias de mercado para o negócio de moda pautado no discurso da economia criativa.
Mas desvelam e conferem a grandiosa dimensão da vida nesta cidade, que articula a calça
jeans como símbolo de história e conquistas, expondo a calça jeans como base epistemológica
da cultura de Toritama.<br>The meaning of jeans produced by Toritama is a collective construction, the result of joint
actions of a chain of actors that culturally undertake to articulate meanings to this artifact. So,
to contextualize this dynamic of meaning, we seek to understand the discursive dimensions
that mark the cultural production of jeans in the fashion field in Toritama, from the actors
chain perspective that act as cultural producers. In this scenario, the study follows the
theoretical and methodological approach suggested by Du Culture Circuit Gay et al. (1997a),
derived from the tradition of Cultural Studies. As a way to access the field of jeans production
of subjectivities in the town of Toritama they were conducted semi-structured interviews with
06 representative players in the production chain, which drive and demarcate the subjective
production of jeans as a fashion product. Data analysis was guided with the support of -
Discourse Analysis (AD) - in the perspective proposed by Gil (2002). The considerations on
the research findings point to a cultural production that means not only Toritama jeans in
fashion, but the whole way of life and cultural values of this city. Therefore, before the
arguments in the research findings, the final considerations suggest that fashion in Toritama
through the jeans, appears as a tangle of cultural discourses and power for disputes. Which
fall under minimally market strategies for the fashion business guided the discourse of the
creative economy. But they unfold and give the great dimension of life in this city, which
articulates the jeans as a symbol of history and achievements, exposing the jeans as
epistemological basis of Toritama culture.

Full textAbstract:
La vegetazione di ambiente montano è nota per essere sensibile alle variazioni climatiche. Il forte gradiente climatico altitudinale, che caratterizza le aree montane, dà luogo ad un marcato gradiente ecologico, in cui numerosi ecotoni sono presenti in una piccola area. Sequenze polliniche investigate all’interno o poco al di sopra dell’ecotono attuale della timberline sono archivi ideali per investigare le relazioni esistenti fra clima ed ecosistemi. Ricostruzioni quantitative delle condizioni climatiche del passato da record pollinici fossili richiedono la comprensione della rappresentazione pollinica attuale lungo gradienti climatici ed ecologici. Obbiettivi di questa ricerca di dottorato sono: lo sviluppo di transetti altitudinali di polline-vegetazione-clima attuale, l’elaborazione di modelli e la loro validazione per valutare le relazioni polline-clima grazie a gradienti altitudinali, la ricerca di nuovi archivi naturali ad alta risoluzione per ottenere dati proxy e ricostruire le variazioni paleoambientali e paleoclimatiche durante l’Olocene, l’applicazione di questi modelli ai dati pollinici stratigrafici ed infine il confronto dei risultati con diverse ricostruzioni su base proxy. E’ stata dimostrata l’importanza di transetti altitudinali locali con campioni pollinici moderni e temperature sito-specifiche come strumento per le ricostruzioni climatiche. Sono stati sviluppati due transetti altitudinali (la Valle di La Thuile e l’Alta Val Brembana) per ottenere consistenti correlazioni locali polline-clima, per trovare taxa pollinici sensibili utili per le ricostruzioni paleoclimatiche, per stimare gli effetti di parametri locali (lapse rate, clima, trasporto di polline verso l’alto e impatto antropico) e infine sono stati utilizzati come test sets per valutare i modelli polline-clima basati su calibration sets estratti dall’European Modern Pollen Database. Sono state investigate le relazioni rappresentazione pollinica attuale-vegetazione-clima lungo un gradiente altitudinale in Alta Val Brembana. Qui la rappresentazione pollinica attuale (trappole polliniche e campioni di muschio), vegetazione, quota e clima sono stati rilevati in 16 siti di campionamento situati lungo un gradiente altitudinale da 1240 m slm a 2390 m slm. I risultati della CCA mostrano una buona concordanza con studi precedenti, che hanno individuato la quota come il maggior gradiente nella variazione della rappresentazione pollinica attuale e della vegetazione in aree montane. Lo studio stratigrafico di proxies paleoecologici e sedimentari nella torbiera Armentarga hanno permesso di ricostruire la vegetazione e il clima negli ultimi 10 ka in un distretto oceanico di alta quota delle Alpi Italiane. Sono state ottenute e validate ricostruzioni quantitative di Tluglio e Pann applicando funzioni di trasferimento create da un vasto dataset di calibrazione polline-clima. Il record paleobotanico proveniente dalla torbiera Armentarga ha mostrato che questa composizione altitudinale della vegetazione è principalmente guidata da un aumento di precipitazioni nel medio-tardo Olocene, indipendente dalle sequenze millenarie di anomalie termiche già note da altri proxies alpini di alta quota (ad es. ghiacciai, timberline, chironomidi, speleotemi). Le variazioni delle precipitazioni annuali durante l’Olocene sono avvenute in tre step principali, partendo da un inizio Olocene moderatamente umido, caratterizzato dalla presenza precoce di foreste di Alnus viridis e seguito da un primo incremento delle precipitazioni a partire da 6.2 ka cal BP. Uno step prominente in avanti avvenne nella transizione medio-tardo Olocene, datata alla torbiera Armentarga tra 4.7 e 3.9 ka, che ha portato verso i valori attuali tipici di clima oceanici montani (Pann 1700-1850 mm) ed è stato probabilmente accompagnato da un incremento di precipitazioni nevose e runoff ed ha avuto un maggior impatto sulla depressione della timberline e l’espansione di praterie.<br>Montane vegetation is traditionally known to be particularly sensitive to climate changes. The strong elevational climatic gradient that characterises mountain areas results in a steep ecological slope, with several ecotones occurring in a small area. Pollen sequences investigated in or shortly above the modern timberline ecotone are ideal archives to analyze the relationships between climate and ecosystems. Quantitative reconstruction of past climate conditions from fossil pollen records requires understanding modern pollen representation along climatic and ecological gradients.
The aims of this PhD research are the development of modern pollen-vegetation-climate elevational transects, model processing and validation for evaluating pollen-climate relationships thanks to elevational gradients, looking for new high-resolution natural archives to obtain proxy data and to reconstruct paleoenvironmental and palaeoclimatic changes during the Holocene, the application of these models to pollen-stratigraphical data and comparing the results with different proxy-based reconstructions.
The importance of local elevational transects of modern pollen samples with site-specific temperature as a tool for paleoclimate reconstructions in the Alps was demonstrated. The two elevational transects (La Thuile Valley and Upper Brembana Valley) were developed to derive consistent local pollen-climate correlations, to find sensitive pollen taxa useful for paleoclimate reconstructions; to estimate the effects of local parameters (elevational lapse rate, climate, uphill pollen transport and human impact) and were used as test sets to evaluate pollen-climate models based on calibration sets extracted from the European Modern Pollen Database. Modern pollen assemblages-vegetation-climate relationships along an elevational gradient in the Upper Brembana Valley were investigated. Here modern pollen assemblages (pollen traps and moss samples), vegetation, elevation and climate have been collected at 16 sampling sites placed along an elevational gradient stretching from 1240 m asl to 2390 m asl. The results of CCA analysis demonstrated a general good agreement with previous studies, which identified elevation as the main gradient in the variation of modern pollen and vegetation assemblages in mountain areas.
The stratigraphic study of paleoecological and sedimentary proxies in the Armentarga peat bog allowed to reconstruct the vegetation and climate history during the last 10 ka in a high-elevation, oceanic district of the Italian Alps. Quantitative reconstructions of Tjuly and Pann were obtained and validated by applying numerical transfer functions built on an extensive calibration pollen-climate dataset. The palaeobotanical record of the Armentarga peat bog has shown this elevational vegetation arrangement to be primarily driven by a Middle to late Holocene precipitation increase, substantially independent from the millennial sequence of thermal anomalies already known from other high-elevation Alpine proxies (i.e. glaciers, timberline, chironomids, speleothems). Changes in annual precipitation occurred in three main steps during the Holocene, starting with a moderately humid early Holocene marked by early occurrence of the Alnus viridis dwarf forests, and followed by a first step of precipitation increase starting at 6.2 ka cal BP. A prominent step forward occurred at the Middle to Late Holocene transition, dated between 4.7 and 3.9 ka at the Armentarga site, which led to present values typical for oceanic mountain climates (Pann 1700-1850 mm) and was probably accompanied by increased snowfall and runoff, and had a major impact on timberline depression and grassland expansion.

Full textAbstract:
This dissertation describes our investigation into the regulation and function of the innate immune modulator alkaline phosphatase (ALP). Animal intestine harbors a vast and complex microbial community, the gut microbiota. While resident microbes perform vital functions and confer tremendous benefits on their hosts, they also provide antigens and toxins that provoke host immune responses, which, if uncontrolled, could be detrimental to the host. Our lab previously demonstrated a negative feedback loop mediated by intestinal ALP (ALPI) which promotes immune tolerance to the commensal microbiota in zebrafish. We continue to investigate regulation mechanisms of ALP genes and explore their roles in modulating host-microbe interactions in various models. We have characterized four zebrafish alp genes, and we engineered tools for functional studies of these genes. Phylogenic analyses involving zebrafish alp genes revealed distinct evolution histories of animal ALP genes and implied their diversified functions. We then tested whether the regulation mechanism and the roles of zebrafish alpi were conserved in mice. We found the ALPI gene Akp3 was specifically upregulated by microbiota and played a role in immune education. We demonstrated the contribution of innate immune signaling to animal weight gain induced by high fat diet feeding. Finally, we discovered the positive correlation between neonatal ALPI activity and gestational age, suggesting potential therapeutic value of ALP supplementation for preventing necrotizing enterocolitis development in preterm infants.
This dissertation includes previously published and unpublished co-authored material.

Full textAbstract:
In the two decades between 1970 and 1990, hundreds of people passed through the ALP branches of Leichhardt Municipality. These were predominantly members of what this thesis calls a 'middle class Left', employed in professions and para-professions like teaching or the public service and motivated, to one degree or another, by the social movements and politics of the late 1960's and early 1970's. This is a social history incorporating the life histories of a selection of these people. It is set against the backdrop of conflicts with incumbent, conservative, working class-based political machines and the political climate of the times. The thesis is in four parts. Part I, the introduction, establishes the point of view of the writer as it shapes what is also a 'participant history'. In this context, and that of the oral history interviews, the introduction addresses the relationship between memory and history. Parts II and III are the body of the thesis and each is lead by a 'photo-essay', recognising the complimentary importance of a visual narrative. Part II sets out the broad political topography of the 1970's and early 1980's. Chapter one describes the middle-classing of the ALP in Leichhardt Municipality, set against a review of the principal literature. It then moves through chapters two to four to examine the three loci of middle-classing: Annandale, Balmain and Glebe. Part III moves on into the 1980's when the middle class Left 'takes power'. It examines, in chapter five, the emerging, sharp, divisions among the Left on Leichhardt Council and in the contests for federal and state parliamentary seats. Chapter six examines the deepening of these divisions in the mid to late 1980's, concluding with the climactic struggle over the Mort Bay public housing project. Chapter seven looks at the diaspora of the Labor Left in Leichhardt at the end of the 1980's as the branch membership declined and many sought out political alternatives to the ALP. Part IV brings the thesis to its conclusion, focussing on the complexities and ambiguities of the middle class Left and drawing out the main socio-political themes of the two decades.

Este estudo investiga o sucesso no processo de bilinguismo português/japonês de seis jovens retornados do Japão. Como sucesso no bilinguismo, entendemos pelo caso em que o indivíduo, mesmo após uma longa permanência no Japão e vivência no sistema escolar japonês, tenha conseguido após o seu retorno no Brasil, manter o domínio na lingua japonesa e possuir uma proficiência linguísitica em português suficiente para seu ingresso no ensino superior brasileiro. O referencial teórico sobre bilinguismo foi baseado nos estudos de Skutnabb-Kangas (2008); Cummins (1984); Baker (1993); Nakajima (2010). Foram realizadas entrevistas semiestruturadas presenciais e online, sendo analisados os seguintes três domínios na trajetória de vida desses colaboradores que, baseados em uma auto-avaliação, foram divididos em 2 grupos bilíngues dominantes em português e bilingues dominantes em japonês : (1) ambiente linguístico no Japão (2) atitudes dos colaboradores com os estudos da L1 e L2 e (3) ambiente linguístico no Brasil. O estudo comprovou que o apoio de familiares e de terceiros constitui um fator importante na motivação dos estudos, bem como na superação de desafios surgidos na adaptação linguística e cultural. Foi também observado que os colaboradores de ambos os grupos tiveram que investir na aprendizagem da língua por um longo período para o desenvolvimento da proficiência linguística acadêmica ALP (Cummins, 2001; 2011) até o ingresso na faculdade. Em relação à rede de apoio formal, foram verificadas as seguintes ações para minimizar os problemas relacionados ao não domínio da língua japonesa no contexto de imigração no Japão: ingresso em escola pública de região com alta concentração de brasileiros, ingresso em faculdade japonesa por programa especial para retornados e ingresso em escola brasileira ações essas realizadas pelos colaboradores do grupo dominantes em português. Por outro lado, os do grupo dominantes em japonês utilizaram as seguintes medidas para facilitar a adaptação linguística e escolar no Brasil: ingresso em escola privada com curso curricular de japonês, ingresso em escola técnica e ingresso em escola pública estadual.

Concluiu-se que o uso dessas redes de apoio formais infuenciou positivamente no desenvolvimento da ALP dos colaboradores.<br>The study herein aims to investigate success in the process of Portuguese/Japanese bilingualism of six youngsters returned from Japan. In our view, successful bilingualism happens in those cases in which even after a long stay in Japan along with an experience with the Japanese school system, the individual has managed to keep his mastery of the Japanese language after returning to Brazil, and be proficient enough in Portuguese so as to be admitted to Brazilian higher education. The theoretical framework on bilingualism was based on studies of Skutnabb-Kangas (2008); Cummins (1984); Baker (1993); Nakajima (2010). Both in-person and online semi-structured interviews have been conducted focusing on three aspects in the life trajectory of interviewees who, based on self-evaluation, have been divided into two groups: Portuguese-dominant bilinguals, and Japanese-dominant bilinguals: (1) linguistic environment in Japan (2) attitude of interviewees with the study of both L1 and L2; and (3) linguistic environment in Brazil. The study has proved that support both from family and others is key to generate motivation for studies, as well as to foment the overcoming of problems arising from both linguistic and cultural adaptation. It has also been observed that interviewees in both groups had to invest on language learning for a long period of time to develop academic linguistic proficiency ALP (CUMMINS, 2001; 2011) until they were admitted to college. As for the formal support network, the following actions aiming at alleviating problems concerning nonmastering of Japanese language in the context of Japanese immigration in Japan have been taken: admission to a public school in an area with a high concentration of Brazilian people; admission to a Japanese college by means of a program specially designed for returned, and admission to a Brazilian school, being all those actions taken by interviewees in the Portuguese-dominant group. On the other hand, those in the Japanese-dominant group have taken the following measures to facilitate linguistic and school adaptation in Brazil: admission to a private school with Japanese language in the syllabus, admission to a technical school, and admission to a state public school. Attendance to college entrance examination prep courses has been observed in both groups. it has been concluded that the use of those formal support networks has had a positive impact on the development of ALP of interviewees.

Full textAbstract:
cience, despite being one of the most universal social endeavours of mankind, is not equally practiced everywhere in the world. Science maintain different roles in different protected areas. As a result, there are regions where scientific information is created more frequently. At the same time, different places are following different scientific paths. It is no surprise that Yellowstone National Park is involved in the creation and circulation of studies on wildlife and the effects of climate change, and produce scientific research more than any other protected area in the world. Conversely, it is highly surprising that climate change science can be completely excluded by the research activities carried in some protected areas in the Alps. International monitoring initiatives, in the meantime, are promoting the circulation of science beyond borders, and providing us with data and powerful images of the effects of climate change from all parts of the world. It is normal, in our everyday scientific landscape, to see proofs of new pioneer species settling in mountaintops in the Tien Shan Range, while living at the foothills of the Alps. We are accustomed to seeing pictures of glacier melting in National Parks in the Andean Cordillera while we spend time monitoring the upward and northward distributional shift of butterflies species in the Rocky Mountains. However, we seldom inquire in the precise geography of the distribution of scientific research. Which protected areas in which regions are producing more research? What are the factors that influence distribution? This work aims at filling exactly this gap, with a particular focus on the Alpine range.

Full textAbstract:
In questa tesi si applica un’indagine multidisciplinare guidata dall’analisi strutturale per studiare l’evoluzione tettono-metamorfica di rocce ultrafemiche appartenenti a unità ofiolitiche affiorati nella parte occidentale delle Alpi o intrappolate nel basamento prealpino durante la collisione varisica. L’analisi si focalizza sulla Zona Zermatt-Saas (ZSZ) in alta Valtournanche (AO), al contatto di questa zona e la parte esterna del bordo meridionale della Zona Sesia Lanzo nella Valli del Tesso e del Tessuolo (TO) e nel Massiccio dell’Argentera, in alta Valle Gesso (CN). Le prime due aree si trovano nella Zona Piemontese che include unità derivanti da litosfera oceanica ristrutturate durante la convergenza alpina. L’ultima zona è situata nei Massicci Cristallini Esterni delle Alpi che includono in prevalenza rocce di origine continentale con scarsi relitti di rocce di probabile origine oceanica, ristrutturate e pervasivamente riequilibrate durante il ciclo Varisico. L’analisi meso- e micro-strutturale è stata integrata dall’analisi minero-chimica, dalle stime termo-barometriche e dalla modellazione petrologica delle associazioni di minerali metamorfici all’equilibrio, dalla datazione radiometrica dei fabric e dall’analisi geochimica di micro-domini selezionati.
Le serpentinite di Créton in Valtournanche sono state interpretate come una scaglia di litosfera originariamente adiacente alla dorsale medio oceanica della Tetide Alpina, metasomatizzata e percolata da Fe- e Mg-gabbri, che ha raggiunto condizioni di ultra alta pressione (UHP) durante la convergenza Alpina, come registrato dalle associazioni a Ti-chondrodite e Ti-clinohumite, precedentemente allo sviluppo della foliazione di alta pressione, dominante a scala regionale, e datata a 60-70 Ma. Il paragone delle condizioni metamorfiche registrate con un modello numerico di subduzione Alpina ha convalidato l’evoluzione ricostruita e ha permesso di restaurarne la posizione nel sistema di subduzione in funzione dell’evoluzione termo-barica dedotta per queste rocce.
La serpentinite di Gias Vej in Valle del Tesso ha registrato un’evoluzione strutturale comune alle rocce ofiolitiche e continentali ad essa adiacenti e ha raggiunto un picco metamorfico eclogitico, come testimoniato dalle paragenesi di alta pressione a Ti-clinohumite, durante la subduzione Alpina.
Presso il Lago Brocan dell’alta valle Gesso in Argentera, boudins di serpentinite e diopsidite, associati a boudins di anfibolite e marmi, si trovano avvolti e allineati dalla foliazione migmatitica regionale di età tardo-Varisica. Essi verosimilmente rappresentano, analogamente alle rocce Alpine studiate, i relitti della sutura dell’oceano Reico, riequilibrati in condizioni di alta temperatura-bassa pressione e trasposti durante la collisione Varisica ed il successivo collasso tardo orogenico.
In conclusione, i risultati ottenuti mostrano come l’utilizzo integrato di tecniche laboratoriali e modellistiche, basate su un solido lavoro di terreno, possano descrivere e individuare unità tettono-metamorfiche nei domini di affinità oceanica in catene montuose risultanti da uno o più cicli di Wilson e dare un contributo alla ricostruzione delle loro evoluzione geodinamica, anche quando scaglie di crosta oceanica sono frammentate e disperse nella cicatrice profonda di un’antica sutura continentale.<br>The tectono-metamorphic evolution of serpentinites and associated rocks has been investigated in the Alpine ophiolitic Piemontese Zone (PZ) – in the Zermatt-Saas Zone (ZSZ) and near the Sesia-Lanzo Zone (SLZ) rim – and in the Variscan migmatites of the Argentera External Crystalline Massif (ECM).
Materials selected for laboratory work contain sequences of meso- and microstructural imprints containing parts of the tectonic evolution of both mono- and poly-orogenic environments (in our case the Piemontese Zone in the Penninic of the Western Alps and the Argentera EMC – Provençal domain of the Alpine collisional front at the Alpine belt termination within the Western Mediterranean).
In the Zermatt-Saas Zone serpentinite of Valtournanche, meso- and microstructural analyses have been coupled with petrological investigation, geochemistry, and radiometric dating. In Valtournanche, Créton serpentinite has been interpreted as a slice of mid-ocean ridge lithosphere, affected by gabbroic percolation and hydrothermalism, deeply involved in the Alpine subduction complex, reaching UHP conditions (2.9-3.3 GPa and 600-630 °C) prior to be exhumed at HP conditions 60-70 Ma and incorporated in a mix of slices of oceanic material of heterogeneous origin and metamorphic evolution. Gias Vej serpentinite registered Eclogite facies conditions and was coupled with slices of continental material at the southern border of the Sesia Lanzo Zone before the record of Pmax conditions. At Lake Brocan in Valle Gesso, remnants of serpentinised spinel lherzolite and diopsidite are suggested to represent a most probable vestigial suture zone of the Rheic Ocean in the External Crystalline Massif of Argentera; this relict survived repeated transpositions and dismembering during migmatisation of the deep Variscan crust related to Variscan continental collision.
The obtained results indicate that investigation of ultramafic rocks by a structure-driven multidisciplinary approach, can unravel the most complete memory of the divergent and convergent tectonic evolution of old oceans. Similar investigation strategies of laboratory procedures, based on solid structural fieldwork, may more diffusely support circumscription of tectonic units in ocean-derived sequences and contribute to redefine their translational tectonic trajectories during mountain-building processes.

Full textAbstract:
The timing of the Alpine deformation in the Central Southern Alps (CSA or Orobic Alps) has always been a debated topic, since the scarcity of reliable absolute age constraints has prevented an accurate chronological reconstruction of the evolution of this sector of the European Alps.
In this work, detailed structural analyses performed in different areas of the CSA allowed us to distinguish different compressive features within both the crystalline basement and the sedimentary cover. The integration of these field data with new isotopic data provides time constraints for the reconstruction of the evolution of the CSA during the Alpine orogeny.
In the northern sector of the belt a Variscan polymetamorphic basement is stacked southward on the Permian to Mesozoic cover along two main regional faults (Orobic and Porcile thrusts). Fault zones, slightly postdating a first folding event of Alpine age (D3), experienced a complex evolution through the ductile and brittle deformation regime, showing greenschists facies mylonites overprinted by a penetrative cataclastic deformation (D4). Generation of fault-related pseudotachylytes marks the onset of brittle conditions, lasting up to the youngest episodes of fault activity.
Thrusting along this structures also produced thrusting within the Permian-Triassic cover with the formation of different south-verging thrust stacks. This first thrusting event was followed by the activation of new deeper thrust surfaces leading to the emplacement of three regional anticlines (Orobic Anticlines) which tilted to the south the previously stacked units. During this long compressive stage (Orobic-Porcile thrusts and Orobic Anticlines) the sedimentary cover of the CSA was also involved in thrusting and different stacks of Mesozoic units were emplaced to the south. 40Ar/39Ar dating of the pseudotachylyte matrix of 9 samples from both the Orobic and Porcile thrusts give two separated age clusters: Late Cretaceous (80-68 Ma) and Early to Middle Eocene (55-43 Ma). These new data provide evidence that the pre-Adamello evolution of the CSA was characterized by the superposition of different tectonic events accompanying the exhumation of the deepest part of the belt through the brittle-ductile transition. The oldest pseudotachylyte ages demonstrate that south-verging regional thrusting in the CSA was already active during the Late Cretaceous, concurrently with both the HP metamorphism that affected the Austroalpine units of the eastern Alps, and the development of a syn-orogenic foredeep basin where the Upper Cretaceous Lombardian Flysch was deposited.
In the Early to Middle Eocene a minor reactivation of the Orobic and Porcile thrusts occurred, as testified by the youngest pseudotachylyte ages obtained by 40Ar/39Ar dating. This event was probably related with the closure of the Ligurian-Piedmont and the ongoing of the Europe-Adria collision.
South of the Orobic Anticlines system the Triassic sedimentary succession is stacked into several units bounded by south-verging low-angle thrust faults, which are related to different steps of crustal shortening. Different thrust stacks occur within the Triassic cover between the Como Lake to the west and the Adamello batholith to the east. They usually have an antiformal arrangement and are separated by each other by different N-S trending transverse zones, such as the poorly known Grem-Vedra Transverse Zone (GVTZ), formed during complex deformational phenomena in a transpressional regime coeval with thrust emplacement. The GVTZ formed during the southward imbrication of the older thrust sheets of the Menna-Arera group, strongly interacting with syn-thrust ductile structures, and was reactivated during the growth of the Orobic Anticlines belt. The GVTZ and other transverse zones of the CSA probably reflect the occurrence of pre-existing fault systems that characterize the Norian to Jurassic rifting history of the Lombardian basin, and were reactivated as strike-slip features during Alpine tectonics.
In the Gandino and Presolana areas thrust surfaces are cut by high-angle extensional and strike-slip faults, which controlled the emplacement of hypabissal magmatic intrusions that post-date thrusts motions. Intrusion ages based on SHRIMP U-Th-Pb zircon dating span between 42±1 and 39±1 Ma, suggesting close time relationships with the earliest Adamello intrusion stages and, more in general, with the widespread calc-alkaline magmatism described in the Southern Alps. Fission track ages of magmatic apatites are indistinguishable from U-Pb crystallization ages of zircons, suggesting that the intrusion occurred in country rocks already exhumed above the partial annealing zone of apatite (depth < 2-4 km).
These data indicate that the northern and central sectors of the CSA were already structured and largely exhumed in the Middle Eocene and no major internal deformations has occurred in these areas after the Bartonian. Neogene deformations were instead concentrated further south, along the frontal part of the belt (Milano Belt).
These new data provide a direct evidence that thrusting and nappe stacking were active during Late Cretaceous times not only in the Eastern Alps, but also in the CSA, significantly extending southward the sector of the Alpine belt affected by the Cretaceous orogenic event. In this view, the Late Cretaceous Southern Alps can be interpreted as the south-verging retrobelt of a pre-collisional orogenic wedge, which formed during the subduction of the Alpine Tethys beneath the attenuated northern Adria margin.

Ogni sforzo umano, dalla pianificazione di una vacanza alla gestione di un complesso processo di produzione, è governato da processi.
I processi possono essere ottimizzati dall’esperienza oppure da accurate indagini scientifiche. È molto comune, in ambienti industriali, svolgere attività ripetitive e che richiedono il coinvolgimento di più risorse. Le attività che le aziende sono tenute a svolgere per completare il proprio business stanno diventando sempre più complicate, e richiedono l’interazione di più persone e sistemi eterogenei. Nel tentativo di affrontare queste sfide, l’informatica e molte tecnologie dell’IT sono state sfruttate per gestire i processi aziendali.
Le tecnologie esistenti permettono di modellare, gestire e ricavare informazioni dai processi aziendali, attraverso diversi strumenti. Veri e propri linguaggi, che fanno da base a strumenti automatici, sono stati sviluppati a questo scopo.
Nuove sfide in questo settore sono: la gestione e la modellazione di processi incompleti o la simulazione di processi reali. Ciò molto spesso è ostacolato dall’indisponibilità di dati e di conseguenza dalla manca di conoscenza, oppure capita che, seppur presenti, i dati risultino inconsistenti.
Oggetto di questa tesi è lo studio e la valutazione di metodi per la generazione di tracce positive e negative, ovvero tracce non conformi ad un dato modello. Ciò viene affrontato in maniera teorica, utilizzando il framework logico abduttivo SCIFF come supporto per la generazione di tracce.
Dopo un'introduzione sul settore di ricerca e una definizione dello stato dell'arte, viene introdotto il framework SCIFF e la metodologia con la quale opera per la gestione dell'incompletezza dei log e la generazione di essi partendo da un modello.

Full textAbstract:
This project is focused on understanding the processes of failure evolution (from triggering to propagation) and deformation mechanisms of Deep Seated Gravitational Movement (DSGSD) and Rock Avalanches (RA) in massive brittle rock slopes. In particular, the focus of this work is directed to the failure mechanism of these phenomena, the influence of failure mechanisms on the slope stability and dynamics of the collapse. This research aims to improve the understanding and modeling of brittle fracture and progressive failure in massive metamorphic rock slopes though a combination of structural geology, geomechanics, geomorphology, numerical and experimental modeling.
Triggering factors and failure mechanisms were study on one mass wasting phenomena in the Easten Alps (Ridnaun Valley Rock Avalanche). The left slope of the Ridnaun Valley (Sterzing/Vipiteno, South Tyrol, Italy), set on the crystalline units of the Austoalpine Nappe of the alpine orogenic wedge, shows evidence of quaternary gravitational evolution which highly depends on the brittle/ductile structural setting of the slope. Detailed field work and LiDAR-derived digital elevation model analysis clearly revealed different gravitational movements. A fully evolved gravitational collapse, having the typical features of a Rock Avalanche (RA), characterizes the central part of the slope; whereas to the east and west of the RA, deep - seated gravitational slope deformations, pointed out for the first time with this research, still involve the slope.
Making use of different approaches, such as geomorphology, structural geology and geomechanical analysis, and numerical modeling, the present work shows how the brittle/ductile tectonic setting acts on one hand as primary controlling factors of the detected large mass movements; on the other hand, can control the evolutionary type of failure (i.e.: rock avalanche).
It is expected that the findings obtained through this investigation will enhance our fundamental knowledge on DSGSD evolutionary type on poly - deformed metamorphic masses, particularly with regard to understanding the key stages of the progressive evolution of rock slope failures from a secondary creep stage to the sudden collapse.<br>Questo progetto di ricerca ha come focus la comprensione dei meccanismi di deformazione e di collasso (dall'innesco alla prpagazione della rottura) che governano Deformazioni Gravitative Profonde di Versante (DGPV) e valanghe di roccia (rock avalanches) in versanti rocciosi. In particolare, l'attenzione primaria di questo lavoro è indirizzata ai meccanismi di propagazione della rottura, alla loro influenza sulla stabilità dei versanti ed alle dinamiche del collasso. Lo scopo principale è migliorare le conoscenze ed i modelli relativi ai meccanismi di fratturazione e di rottura progressiva in ammassi rocciosi foliati, attraverso un approccio multidisciplinare che prevede l'analisi delversante con tecniche geologico - strutturali, geomorfologhiche, geomeccaniche e di modellazione numerica.
Cause innascanti e meccanismi di rottura progressiva sono stati analizzati prendendo come caso studio un collasso gravitativo di grandi dimensioni nelle Alpi orientali (la rock avalanche della Val Ridanna). Il versante sinistro della Val Ridanna (Sterzing/Vipiten, Alto Adige, Italia), collocato geologicamente nelle unità cristalline della falda Austroalpina del prisma orogenetico delle Alpi, mostra evidenze un'evoluzione gravitativa quaternaria di tipo differenziale, la quale è fortemente controllata dall'assetto geologico duttile/fragile delle unità metamorfiche costituenti il versante. Indagini di terreno, unita ad una dettagliata analisi del modello digitale del terreno ottenuti da acquisizioni LiDAR, ha permesso di riconoscere differenti deformazioni gravitative all'interno del versante studio. La parte centarle della valle è caratterizzata da un evidente accumulo derivante da un collasso gravitativo di tipo rock avalanche; lungo il verante, ad ovest ed ad est dell'area sorgente della rock avalanche, due DGPV, riconosciute per la prima volta grazie a questo lavoro, coinvolgono il versante.
Il presente lavoro mostra come l'assetto duttile/fragile agisca da un lato come fattore predisponente alle deformazioni gravitative riconosciute; dall'altro controlla direttamente le modalità evolutive delle deformazioni stesse.
Si ritiene che i risultati ottenuti da questa tesi di dottorato possano contribuire al miglioramento delle conoscenze sull'evoluzione di DGPV in rocce metamorfiche polideformate, in particolare per quanto concerne i meccanicsmi che governano l'evoluzione parossistica di un ammasso roccioso in deformazione lenta.

Full textAbstract:
The overarching goal of the doctoral thesis was thus the development of a systematic procedure capable to examine and enhance the role of geomechanical and climatic processes in rockfall susceptibility, performed with statistically based and Machine Learning techniques. To achieve this purpose, two case studies were analysed in the Italian Alps (Valchiavenna, Lombardy Region; Mountain Communities of Mont Cervin and Mont Emilius, Aosta Valley Region).
For both case studies, Generalized Additive Models (GAM) were used for rockfall susceptibility assessment; for the Valchiavenna case study, a Random Forest (RF) model was tested too. All models were validated through k-fold cross validation routines and their performance evaluated in terms of area under the receiver operating characteristic curve (AUROC). Predictors’ behaviour physical plausibility was verified through the analysis of the mathematical functions describing the predictors-susceptibility modelled relationships. Specific objectives of the two case studies differed.
The Valchiavenna case study was dedicated to testing the role of the outcrop-scale geomechanical properties in a rockfall susceptibility model. Specific objectives were: (i) the optimal selection of sampling points for the execution of geomechanical surveys to be integrated within an already available dataset; (ii) the regionalization over the study area of three geomechanical properties, namely Joint Volumetric Count (Jv), rock-mass weathering index (Wi) and rock-mass equivalent permeability (Keq); (iii) the implementation of the regionalized properties as predictors in a rockfall susceptibility model, along with the traditional morphometric variables; (iv) the investigation of prediction limitations related to inventory incompleteness; (v) the implementation of a methodology for the interpretation of predictors’ behaviour in the RF model, usually considered a black box algorithm; (vi) the integration of the RF and GAM outputs to furnish a spatially distributed measure of uncertainty; (vii) the exploitation of satellite-derived ground deformation data to verify susceptibility outputs and interpret them in an environmental management perspective.
The additional geomechanical sampling points were selected by means of the Spatial Simulated Annealing technique. Once collected the necessary geomechanical data, regionalization of the geomechanical target properties was carried out by comparing different deterministic, regressive and geostatistical techniques. The most suitable technique for each property was selected and geomechanical predictors were implemented in the susceptibility models. To verify rockfall inventory completeness related effects, the GAM model was performed both on rockfall data from the official landslide Italian inventory (IFFI) and on its updating with a field-mapped rockfall dataset. Regarding the RF model, the Shapely Additive exPlanations (SHAP) were employed for the interpretation of the predictors’ behaviour. A comparison between GAM and RF related outputs was carried out to verify their coherency, as well as a quantitative integration of the resulting susceptibility maps to reduce uncertainties. Finally, the rockfall susceptibility maps were coupled with Synthetic Aperture Radar (SAR) data from 2014 to 2021: a qualitative geomorphological verification of the outputs was performed, and composite maps were produced.
The key results were: (i) geomechanical predictor maps were obtained applying an ordinary kriging for Jv and Wi (NRMSE equal to 13.7% and 14.5%, respectively) and by means of Thin Plate Splines for Keq (NRMSE= 18.5%). (ii) Jv was the most important geomechanical predictor both in the GAM (witha deviance explained of 7.5%) and in the RF model, with a rockfall susceptibility increase in correspondence of the most fractured rock masses. (iii) Wi and Keq were penalized (i.e., they had low influence on rockfall susceptibility) in the GAM model, whereas Keq showed an importance comparable to Jv in the RF model. (iv) In a complex Machine Learning model (RF), the SHAPs allowed the interpretation of predictors’ behaviour, which demonstrated to be coherent with that shown in the GAM model. (v) The models including the geomechanical predictors resulted in acceptable rockfall discrimination capabilities (AUROC>0.7). (vi) The introduction of the geomechanical predictors led to a redistribution of the high-susceptibility areas in plausible geomorphological contexts, such as in correspondence of active slope deformations and structural lineaments, otherwise not revealed by the topographic predictors alone. (vii) Models built with solely the IFFI inventory, resulted in physically implausible susceptibility maps and predictor behaviour, highlighting a bias in the official inventory. (viii) The discordance in predicting rockfall susceptibility between the GAM and the RF models varied from 13% to 8% of the total study area. (ix) From the integration of InSAR data and susceptibility maps, a “SAR Integrated Susceptibility Map”, and an “Intervention Priority Map” were developed as operational products potentially exploitable in environmental planning activities.
The Aosta Valley case study was dedicated to challenge the concept of “susceptibility stationarity” by including the climate component in the rockfall susceptibility model. The availability of a large historical rockfall inventory and an extensive, multi-variable meteorological dataset for the period 1990-2020 were crucial input for the analysis. Specific objectives were: (i) the identification of climate conditions related to rockfall occurrence (ii) the summary of the identified relationships in variables to be used in a susceptibility model; (iii) the optimization of a rockfall susceptibility model, including both topographic, climatic and additional snow-related predictors (from a SWE weekly gridded dataset).
Starting from an hourly meteorological dataset, climate conditions were summarized in indices related to short-term rainfall (STR), effective water inputs (EWI, including rainfall and snow melting), wet-dry cycles (WD) and freeze-thaw cycles (FT). Climate indices and rockfall occurrence time series were paired. Critical thresholds relating rockfall occurrence to climate indices not-ordinary values (>75th percentile) were derived through a statistical analysis. As summary variables for the susceptibility analysis, the mean annual threshold exceedance frequency for each index was calculated. Model optimization consisted in stepwise modifications of the model settings in order to handle issues related to inventory bias, physical significance of climatic predictors and concurvity (i.e., predictors collinearity in GAMs). The starting point was a “blind model”, i.e., a susceptibility model created without awareness of the rockfall inventory characteristics and of the physical processes potentially influencing susceptibility. To reduce the inventory bias, “visibility” masks were produced so to limit the modelling domain according to the rockfall collection procedures adopted by administrations. Thirdly, models were optimized according to the physical plausibility of climatic predictors, analysed through the smooth functions relating them to susceptibility. Finally, to reduce concurvity, a Principal Component Analysis (PCA) including climatic and snow-related predictors was carried out. Subsequently, the obtained principal components were used to replace the climatic predictors in the susceptibility model.
The key results were: (i) the 95% of the rockfalls occurred in severe (or not ordinary) conditions for at least one among the EWI, WD and FT indices; (ii) ignoring inventory bias led to excellent model performance (0.80≤AUROC ≤0.90) but physically implausible outputs; (iii) the selection of non-rockfall points inside the “visibility mask” was a valuable approach to manage the inventory bias influence on outputs; (iv) the inclusion of climate predictors resulted in an improvement of the susceptibility model performance (AUROC up to 3%) in comparison to a topographic-based model; (v) the most important physically plausible climate predictors were EWI, WD, with a deviance explained varying from 5% to 10% each, followed by the maximum cumulated snow melting with a deviance explained varying from 3% to 5%. The effect of FT was masked by elevation. (vi) When the climate and snow related predictors were inserted in the susceptibility model as principal components, concurvity was efficiently reduced.
The inclusion of climate processes as non-stationary predictors (i.e., considering climate change) could be a valuable approach both to derive long-term rockfall susceptibility future scenarios and in combination with short-term weather forecasts to adapt susceptibility models to an early warning system for Civil Protection purpose.

Au cours des dernières décennies, l’industrie des semi-conducteurs a connu une augmentation spectaculaire de la performance des circuits intégrés. La photolithographie, un procédé indispensable à la fabrication des circuits intégrés, requiert désormais une séquence d'étapes de plus en plus complexes, comprenant de nombreux traitements successifs tels que le Self-Aligned Double Patterning (SADP) et le Self-Aligned Quadruple Patterning (SAQP). Au-delà de leur complexité et de l’augmentation des coûts associés, les étapes de patterning engendrent des erreurs d’alignement (Edge Placement Error (EPE)) qui affectent le bon fonctionnement des dispositifs. L’objectif de la thèse est de développer un nouveau procédé de dépôt sélectif topographique (TSD) par une approche en super-cycle « Dépôt/Gravure ». Les avantages d’un dépôt TSD est de réaliser latéralement et directement des espaceurs sur les flancs latéraux des architectures 3D telles que les grilles des transistors CMOS à l’échelle du nanomètre. Cette nouvelle stratégie de fabrication permet tout d’abord d’envisager une réduction du nombre des étapes et d’équipements nécessaires à la structuration, limitant ainsi les EPE potentiellement induites par la photolithographie. Ainsi, elle offre la possibilité de réduire la consommation des surfaces horizontales des transistors 3D, qui est un des éléments critiques à prendre en compte lors de réalisation des espaceurs dans l’intégration des nœuds technologiques avancés. Une preuve de concept du dépôt TSD a fait l’objet de ma thèse grâce à une approche en super-cycle reposée sur l’alternance d’un procédé de dépôt conforme par PE(ALD) suivi par différents procédés de gravure plasma anisotrope dans un seul et même équipement, en utilisant les propriétés physiques et chimiques d’interactions des plasmas avec les matériaux<br>Over the past decades, the semiconductor industry has witnessed a remarkable increase in the performance of integrated circuits. Photolithography, a crucial process in the manufacturing of integrated circuits, requires an increasingly complex sequence of steps, including various successive treatments such as Self-Aligned Double Patterning (SADP) and Self-Aligned Quadruple Patterning (SAQP). Beyond their complexity and the associated cost escalation, patterning steps can result in alignment errors, known as Edge Placement Error (EPE), which can impact the proper functioning of devices such as transistors. The objective of this thesis is to develop a novel topographical selective deposition (TSD) process using a "Deposition/Etching" super-cycle approach. The advantages of this TSD process include the lateral and direct formation of spacers on the sidewalls of 3D architectures, such as CMOS transistor gates at the nanoscale. This innovative manufacturing approach paves the way for reducing the number of steps and equipment required in the fabrication process, minimizing the potential EPE introduced by photolithography. Consequently, it offers the opportunity to reduce the consumption of horizontal surfaces in 3D transistors, a critical factor in the integration of advanced technological nodes during spacer creation. This work offers a proof of concept of the TSD deposition, using a super-cycle approach that alternates between a conformal deposition process by PE(ALD) and various anisotropic plasma etching processes in the same tool. This approach leverages the physical and chemical properties of plasma interactions with materials

Full textAbstract:
The monitoring of ecological condition of grasslands ecosystems in the
European Alps is a main issue for mountain regions, since the abandonment of
traditional and sustainable management practices has exposed grassland habitat
to significant impacts in a context of global environmental change.
The present research project was focused in assessment of the state of
permanent meadows in the lowlands of Valtellina Valley (80 km2), Italian Alps,
during the timeframe 1980-2000. In specific, it quantified the land use/land
cover changes and identified main drivers behind permanent meadows loss;
characterized the relationship between biodiversity in the meadows and the
spatial-environmental conditions in the landscape and by last evaluated the use
of satellite remote sensing data for fast change detection in landscape. To
achieve such aims, the research project was organized in three different
approaches presented in the four chapters of this thesis.
Concerning the quantification of the land use/land cover and identification of
main drivers behind permanent meadows loss, the results show a strong
decrease in meadows (-18.5%) in a context of agricultural land decrease and
human settlements increase. This was the land cover type with highest loss and
conversion rate during the study period. Meadows were converted to human
settlements (urban, industrial and roads), other agriculture uses (cultivation,
orchard, vineyard), bushland and uncultivated land. Meadows loss occurred
mainly in soils with good land capability, low slope, exposed to south and in
proximity of roads, urban settlements and bushland. Densities of urban,
industrial and bushland and land capability were the only significant drivers for
meadows loss, while distance to meadow edge, meadows density, distance to
roads and soil degradation were the only significant drivers for meadows
preservation.
Concerning the characterization of the relationship between biodiversity in the
meadows and the spatial-environmental conditions in the landscape, the results
evidenced that species richness and Shannon indices were best explained by
regressive models including changes occurred in spatial environmental
heterogeneity from 1980 to 2000. Species richness was negatively related to
strong decrease in meadows habitat area and recent urban area, while Shannon
index was positively related to the increase in landscape diversity. In contrast,
species evenness was better explained by regressive model including recent
spatial environmental heterogeneity and positively related to increase ineastness in the study area, and negatively affected both by the area of woody
and soil pH (KCl).
Concerning the evaluation of the use of satellite remotely sensing data for land
cover mapping and change detection in landscape, the results show that the
hybrid approach for land cover classification based of Landsat imagery was
highly accurate. Image differencing is the technique which best detect changes
in landscape as well as in urban, meadow and bush land. The accuracy of
change detection was moderate.
This thesis concludes that the conflict by land in locations densely occupied by
other land cover types with good land capability is the major threat to
meadows and avoidance of fragmentation may be a good strategy for its
preservation. The meadows habitat needs a well-designed landscape and
farming planning, which should account the economic value of the ecosystem
services provided by this habitat. In addition, to conserve plant diversity in
meadows it is necessary to avoid loss of meadows habitat, maintain landscape
diversity and execute a sustainable meadow management.
Remotely sensed imagery can be a reliable source of information for alps,
although particular attention should be made to the image pre-processing and
classification, as well as, to minimize topography effects in spectral
information.

Imagine a school where everyone tries to help the weakest student, and there is no competition among them except for being nice and supportive! Or companies who, instead of competing with their customers, try to make the world a better place! Yes, it is too big of a goal, but every big move starts from a small step. The small step in my thesis is working on the question "how to make groups work together in a better way" applied to the world of artificial intelligence. To train virtual agents to successfully work together, one must overcome the same problems humans face, such as selfishness. While agents might not be selfish, we typically optimize or preferentially select them on their individual performance. Thus, the selfish agents would also win again. To study and remedy this problem, I made a game for multiple artificial agents competing with each other. I also devised different objective functions so that selfishness might not be the optimal strategy. Specifically, Darwin's theory of Evolution and the group selection mechanism provides a different mechanism to incentivize groups to cooperate. The idea is that when evolving agents under these conditions, the last generation will include only cooperating agents. I used a framework that includes an evolvable neural network for implementing the agents and a genetic algorithm working based on specific rewarding schemes. I found that different rewarding schemes result in different agent behavior. Specifically, when agents evolve in groups whose performance is measured by their weakest member, they not only evolve to become an effective group, but they receive rewards more equally.

<p> Addiction to drugs and alcohol is at an all time high. Billions are being spent annually on this epidemic with minimal success (Califano, 2007). Research indicates that drug and alcohol abuse/addiction is one of the major contributing causes to mental health problems (Fletcher, 2013; Sheff, 2013). The purpose of this inquiry is to understand the experience of one client in Integral Recovery (IR). The experience of this client was interpreted through an AQAL lens. Additionally this study used a phenomenological design, the researcher interviewed one client of IR, his mother, and one staff member who regularly worked with the client over the course of three months. After careful analysis of these interviews five key themes related to the IR treatment model emerged: 1) Practices and Structure 2) Obstacles to Recovery 3) Values Integral Recovery 4) Relatedness 5) Optimism. Interview results provided an additional perspective on the experience of an IR client in primary treatment. Future research might consider a longitudinal study with more participants to better understand the success rates of individuals who use IR interventions as their primary means of drug and alcohol treatment.</p>

Full textAbstract:
Les pompes à induction linéaires électromagnétiques (PEM) sont un sujet de recherche important dans le développement des réacteurs rapides refroidis au sodium de génération IV. En particulier, dans le cadre du programme de simulation numérique R&D du Commissariat à l’énergie atomique et aux énergies alternatives (CEA), la prédiction du comportement des pompes à induction linéaires annulaires (ALIP) a été évaluée en raison de ses avantages en termes de sécurité par rapport aux pompes mécaniques.Pour des raisons de sûreté nucléaire, il est nécessaire de connaître le comportement d'une ALIP dans des conditions hors conception. En conséquence, le présent travail se concentre sur l’étude de la phénoménologie magnétohydrodynamique (MHD) et de ses instabilités, ces dernières se produisant lors du passage d’une branche linéaire à une branche non linéaire de la courbe de performance au maximum de pression. Ce phénomène est associé à une diminution conséquente de la pression et du rendement développés par la pompe et intervient dans des régimes de fonctionnement à grand nombre de Reynolds magnétiques (RmB), lequel quantifie la relation convection-diffusion du champ magnétique.Cette recherche vise à développer différents outils permettant de décrire des phénomènes et de prévoir des comportements pour différents régimes de performance. Ce raisonnement a été construit selon trois axes principaux basés sur les recherches bibliographiques plus notables sur le sujet. Ils consistent en i) la caractérisation des principaux effets déclenchés lors de l'opération de l’ALIP à l'aide d'approches théoriques et l'obtention de seuils de stabilité à partir desquels l’écoulement MHD pourrait devenir instable, ii) la mise au point de modèles numériques précis capables de reproduire les comportements physiques proches de ceux des installations réelles et iii) l'observation et l'analyse de phénomènes utilisant différentes méthodes pour le post-traitement de données volumineuses acquises par l'exploitation de l'installation expérimentale PEMDyn, située au centre du CEA Cadarache.Dans ces travaux, la comparaison des résultats obtenus à travers ces trois approches différentes a permis de décrire les instabilités MHD attendues lors de l’opération à grand nombre de Reynolds magnétique de glissement (Rms). Ils sont caractérisés par des pulsations à basse fréquence (LF), des inhomogénéités de vitesse et de champ magnétique, des vibrations, etc. On a obtenu ici que ces phénomènes pourraient être dus à une amplification des perturbations à l'entrée, déclenchée par une certaine valeur de la vitesse de glissement. Cette amplification peut être quantifiée avec des modèles théoriques ou numériques et a été observée lors d'expériences.En outre, cette étude met l'accent sur le niveau de détail requis dans les modèles analytiques et numériques en fonction de leur portée. Un nombre important de modèles avec différentes exactitudes et hypothèses ont donc été développés. Une des conclusions principales extraites montre l’importance des effets de bouts dus à la longueur finie de l’inducteur sur les performances et la stabilité des ALIPs<br>Electromagnetic Linear Induction Pumps (EMPs) are an important research subject in the development of Gen IV sodium-cooled fast reactors. Especially, in the framework of the French Alternative Energies and Atomic Energy Commission’s (CEA) R&D numerical simulation program, the prediction of the behavior of Annular Linear Induction Pumps (ALIPs) is been evaluated because of its safety advantages compared to mechanical pumps.For nuclear safety reasons, it is needed to know the behavior of an ALIP at off-design conditions. Consequently, the present work is focused on the study of magnetohydrodynamic (MHD) phenomenology and instabilities, these last occurring at the transition from linear to non-linear branch of the performance curve at the maximum of pressure. This phenomenon is associated to a consequent decrease of the pump developed pressure and efficiency and takes place at large magnetic Reynolds number (RmB), which quantifies the relation convection to diffusion of the magnetic field.This research aims to develop different tools permitting to describe phenomena and predict behavior for different performance regimes. This reasoning has been constructed following three main axes based on bibliographic researches on the subject. They consist of i) the characterization of main effects triggered during the performance of ALIPs using theoretical approaches and obtaining of stability thresholds from which the MHD flow might become unstable, ii) the development of accurate numerical models able to reproduce physical behavior close to real facilities and iii) the observation and analysis of phenomena using different methods for the post-treatment of big data acquired through the exploitation of the experimental facility PEMDyn, located in CEA Cadarache, France.In this work, the comparison of obtained results through these three different approaches has permitted to describe the MHD instabilities expected at operations with high values of slip magnetic Reynolds number (Rms). They are characterized by low frequency (LF) pulsations, velocity and magnetic field inhomogeneities, vibrations, etc. Here it has been obtained that these phenomena might be due to an amplification of inlet perturbations, triggered by the value of the slip velocity. Such amplification may be quantified with theoretical or numerical models, and has been observed on experiments.Furthermore, the current study puts the accent on the required level of detail in analytical and numerical models depending on their scope, and thus, an important number of models with different accuracies and assumptions has been developed. One of main conclusions extracted shows the importance of end effects due to the finite length of the inductor on the performance and stability of ALIPs

Full textAbstract:
In this work, the electronic band structure of III (In, Al, Ga) - V (N, As, Sb)
compounds and their ternary alloys have been investigated by density functional
theory (DFT) within generalized gradient approximation (GGA) and empirical
tight binding (ETB) calculations, respectively.
The present DFT-GGA calculations have shown direct band gap structures
in zinc-blende phase for InN, InAs, InSb, GaN, and GaAs. However, indirect
band gap structures have been obtained for cubic AlN, AlSb and AlAs com-
pounds<br>here, the conduction band minima of both AlN and AlAs are located at
X symmetry point, while that of AlSb is at a position lying along Gamma- X direction.
An important part of this work consists of ETB calculations which have been
parameterized for sp3d2 basis and nearest neighbor interactions to study the band
gap bowing of III(In<br>Al)- V(N<br>As<br>Sb) ternary alloys. This ETB model provides
a satisfactory electronic properties of alloys within reasonable calculation time
compared to the calculations of DFT. Since the present ETB energy parameters reproduce successfully the band structures of the compounds at ¡<br>and X symme-
try points, they are considered reliable for the band gap bowing calculations of
the ternary alloys.
In the present work, the band gap engineering of InNxAs1¡<br>x, InNxSb1¡<br>x,
InAsxSb1¡<br>x, Al1¡<br>xInxN, Al1¡<br>xInxSb and Al1¡<br>xInxAs alloys has been studied
for total range of constituents (0 <<br>x <<br>1). The downward band gap bowing
seems the largest in InNxAs1¡<br>x alloys among the alloys considered in this work.
A metallic character of InNxAs1¡<br>x, InNxSb1¡<br>x and InAsxSb1¡<br>x has been ob-
tained in the present calculations for certain concentration range of constituents
(N<br>As) as predicted in the literature. Even for a small amount of contents (x),
a decrease of the electronic e®<br>ective mass around ¡<br>symmetry point appears for
InNxAs1-x, InNxSb1-x and InAsxSb1-x alloys manifesting itself by an increase
of the band curvature. The calculated cross over from indirect to direct band gap
of ternary Al alloys has been found to be consistent with the measurements.
As a last summary, the determinations of
the band gaps of alloys as a function of contents, the concentration range of con-
stituents leading to metallic character of the alloys, the change of the electronic
effective mass around the Brillioun zone center (Gamma) as a function of alloy contents,
the cross over from indirect to direct band gap of the alloys which are direct on
one end, indirect on the other end,
are main achievements in this work, indispensable for the development of mate-
rials leading to new modern circuit components.

A importância do estudo do Islão em contexto indiano advém do facto de um terço
dos muçulmanos existentes hoje em dia no Mundo viverem nessa região e do facto de,
no período agora em estudo, o império britânico ter sido a entidade política com mais
muçulmanos precisamente porque a Índia estava sob administração da Grã-Bretanha.
Por outro lado, no ano de 2007, que assinalou precisamente os 60 anos da

La coopération d'aide au développement est née au lendemain de la Seconde Guerre mondiale. Sans conteste, la Plan Marshall constitue un exemple frappant d'aide économique à une vaste échelle géographique. Toutefois, il y a une trentaine d'années, un évènement historique, la décolonisation, bouleversait les rapports internationaux. La vague des indépendances faisaient disparaître les liens juridiques qui unissaient colonisateurs et colonisés. Cette mutation profonde et définitive débouchait sur des rapports nouveaux fondés sur une volonté commune de développement. C'est ce qu'on appellera très vite la coopération. La coopération Etats ACP/UE a plus de quarante ans et son existence date de la création de la Communauté économique européenne qu'institue le traité de Rome du 25 mars 1957. Si les premiers rapports d'association CEE/Pays et territoires d'Outre-mer s'inscrivent dans le cadre défini par la quatrième partie du traité CEE, l'entrée en vigueur de la première convention de Yaoundé, le 20 juin 1964, modifie en profondeur ces rapports, notamment avec les indépendances des associés au traité qui réclament également leur indépendance économique, sans laquelle l'indépendance politique n'est qu'un vain mot. . .
