Abstract:
This thesis seeks to challenge deficit approaches to 'different' childhoods. It does this through documenting the everyday life experiences of Sylheti-heritage Muslim children in urban Scotland, and reading these childhoods through the lives of children and their kin in rural Sylhet, Bangladesh. The research is based on 3 years' ethnographic fieldwork (January 2008-February 2011), in Scotland and in Bangladesh, and incorporates various child-friendly creative research methods used to elicit data on children's realities and perspectives on their lives. These data are supplemented by data from the children's mothers (and occasionally wider family) in both locations. Transnational migration between the Indian subcontinent and the UK is not new, but little research has focused on childhoods, in particular the lived experiences of young Muslim children of marriage-migrant mothers in Scotland, where this minority ethnic 'community' is quite small, later-formed and largely invisible. Little early childhood research has been conducted on children's everyday lives either in rural Sylhet or in Scotland. The history and context of migration and the realities of children's lives in Scotland, as migrant-heritage Muslim children, are largely unexplored and their particular needs are little understood. Some media and public imaginaries and discourses portray Muslim families and their communities as 'problematic', increasingly so since September 11th, 2001, with recent events in the UK, mainland Europe and the Middle East adding fuel to such sentiments. Many Sylheti-heritage families experience harassment and abuse, or live in fear of such eventualities, and the women and young children in my Scottish cohort have largely withdrawn for safety from the visible public domain. This research aims to contribute to a body of knowledge on early childhood(s). Early childhood interventions are high on Scotland's, and the UK's, policy agendas. These policies aim to create better futures and greater inclusiveness for all residents, but they are problematic for families that do not match the very Euro-American middle-class conceptions of childhood and family norms that inform policy. Despite the introduction of strengths-based models in family and childhood policy and practice, such 'different' children and families may still be viewed from a deficits perspective. Such deficit discourses may be rooted in a language of cultural deprivation and special needs, focusing on perceived deficiencies, resulting in the pathologising of certain groups, which become normalised over time. The global Early Years' agenda is also reflected in interventions in rural Bangladesh, with imported global ideals and norms of which most village families have no knowledge and which bear little relevance to their everyday lives. For example, many interventions exist for early childhood in the form of pre-school and nursery provision, but many are based on very Eurocentric models of childhood, which although pertinent in the Global North may not 'fit' with the realities of life for most rural children and their families. There is an over-emphasis on children's futures and children as 'becomings', the future citizens they will become, rather than on their quality of life here and now as 'beings'. This thesis frames children's everyday lives in terms of 'domains': places of childhood (locations of children's day-to-day activities), 'networks': spaces of childhood (social networks and relationships with kin and friends); and 'preoccupations': pursuits of childhood (how they spend their lives and what meaning, if any, they attach to these different aspects of life). The gendered character of these experiences is highlighted throughout. Children's lives, particularly when young, are influenced and shaped by their kin, yet opportunities for agency also exist. When women migrate after marriage from Sylhet to Scotland, some aspects of childhood and family lives remain fairly constant while others change quite radically. For instance, whilst children's lives continue to be centred on close family, family may be much smaller and less accessible than in Sylhet. Concepts of house and neighbourhood continue to be important, but Sylheti village childhoods are largely spent outdoors, whilst children are largely restricted to the family home in Scotland; children's physical domains of activity diminish and women and children have few opportunities to connect socially beyond their existing family networks, particularly in the early years. Social life, very rich and foregrounded in Sylheti villages, becomes potentially more restricted in Scotland although women work hard to create and maintain social opportunities and networks in Scotland, with wider Diasporic kin, and the Sylheti villages to which they have connections. Through their representations and narratives, both drawn and spoken, children convey rich examples of their childhood experiences, in both locales, which challenge deficit discourses on 'different childhoods'.

Abstract:
This thesis is about children and transnationalism. It is about the way in which children develop their identities in transnational communities in societies being transformed by globalisation. It is about the reproduction of societies through the socialisation of children and the tension inherent between this reproduction and social change. I set out to study children but became interested in adults' interactions with children and the nature of transnational communities and identities. As my fieldwork progressed I was drawn away from children into a study of families and societies. So, while children are the empirical focus of this thesis, there are many complementary sections which draw on evidence from adults or only discuss adults. As my description of Shirin and her brother above illustrates, processes and tensions are mediated by children often through seemingly contradictory attitudes and practices. I will investigate this phenomenon of contradiction and ambivalence as it characterises the experiences of the British Bangladeshi children I focus on and is key to understanding way in which identities are formed and experienced. [It] was conceived as part of the research project ‘Home and Away: South Asian Children's Representations of Diaspora', which was managed by my supervisor, Dr. Katy Gardner and Dr. Kanwal Mand. One aim of the project was to address a gap in research on the views of transnational children on issues of culture, belonging and identities. The project aims to investigate and bring to the fore the influence of the life course in migration research. This thesis contributes to these aims, but on its own can make only a partial contribution to this field. It is a snapshot of just over a year in the lives of a group of about twenty British Bangladeshi children between the ages of 8 and 12. Added to this material is additional data collected from a wider group of children in less depth, from younger and older siblings and from parents and other adults.

Abstract:
This thesis examines the health seeking practices of the mentally ill in Sylhet, Bangladesh. Previous work has suggested that in the Islamic world local traditional healing is being undenriined by the encroaching global forces of biomedicine and orthodox Islam. However, in Sylhet, traditional healing is thriving. Traditional healing may survive for different reasons. For local women, traditional healers may offer a space for ventilating complaints which is not available elsewhere for affluent ex-pats the opportunity to reassert their Bengali identity. Western biomedicine poses less of a threat to traditional healing as it has become incorporated as a Bangladeshi product and perceived as inefficacious, corrupt and hannful. Conversely, the endurance of traditional healing may lie in its ability to adapt and incorporate Western biomedicine. Muslims do not see anything inconsistent in visiting Hindu healers as any healer is simply the medium through which Allah works.

Full text
Abstract:
Abstract The Surma basin is a part of the Bengal Basin situated in northeastern Bangladesh. The presence of eight gas fields and one oil field makes this an area that is interesting both economically and geologically. In spite of detailed geological and geophysical investigations, information available on palynostratigraphy and geochemistry for the area is scanty. The aim of the present work was to investigate the palynological assemblages, mineralogy and geochemistry of the Surma Group (SG) sequences in Surma Basin, Bangladesh. Core samples (n = 188) were gathered from the wells following: Patharia well-5, Rashidpur well-1, Atgram well-IX, Habiganj well-1, Kailastila well-1 and Fenchuganj well-2. They were provided by BAPEX (Bangladesh Petroleum Exploration Company). X-ray Fluorescence (XRF), Atomic Absorption Spectrometry (AAS), Loss of Ignition (LOI), X-ray diffraction (XRD), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) were used for geochemical and mineralogical study of shale samples. In the palynological study, the distributions of pollens and spores were determined. For data analysis, SPSS computer programme was used. Palynological assemblages of the Surma Group of sedimentary sequence of Bangladesh include taxa range in age from the lower Miocene to the Upper Miocene which can be potentially used in dating and correlation. The Lower Miocene interval is correlated with the Simsang Palynological Zone IV of Meghalaya, India and the Bengal Palynological Zone (BPZ) V. The Upper Miocene is correlated with the Simsang Palynological Zone IV of Meghalaya, India and the BPZ Zone V of Bengal. They were deposited in two types of paleoenvironments ranging from the brackish type to shallow marine to brackish. The sequence contains reworked palynomorphs of BPZ IV and III namely Meyeripollies naharkotensis, Polypodiesporites Oligocenecus, Palmepollenities Eocencus and ornamented Tricolpate pollen of the Eocene-Oligocene age which are mainly encountered in the lower Miocene sediments indicative of increased tectonic activity in the area. Geochemical ratios (SiO2/ Al2O3, Cu/Zn, Maturity = K2O+ Al2O3/Na2O+MgO, Rb/K2O, K2O/Na2O, Cr/Rb, Zr/Rb, V/Rb, Th/U etc.) were useful for determining grain size, maturity, tectonics and environment of deposition. High Ba enrichment was detected in the Patharia well-5 and showed high surface water productivity and diagenetic mobilisation. Tectonic descrimination was achieved using SiO2 and K2O/Na2O ratio. XRD analysis revealed the minerals kaolinite, illite, chlorite, illite/smectite (I/S) and kaolinite/smectite (K/S) mixed layers. Kaolinite/Smectite here reported for the first time in Bangladesh. Clay mineral analyses provided evidence for diagenesis. Smectite diagenesis and dehydration have contributed to the generation of overpressure in the Bhuban Formation in the Patharia well -5. Geochemical ratios of the present study from the Surma Basin is undoubtedly a powerful technique and can be applied to any sedimentary basin analysis to infer the palaeoenvironment, palaeoclimate and palaeotectonics.

Full text
Abstract:
This thesis examines the effects of 'Historical Globalization' on Sylhet and its people from 1874 to 1971. The aim of the thesis is to show two intersecting worlds within which the people of Sylhet lived their lives. At the local level they have responded to the introduction of the capitalist tea plantation. At the global level they established a 'diaspora' and social networks that maintained contact with the homeland. The dissertation considers the reshaping of Sylhet and its role as buffer zone between Assam and Bengal - the biggest province of British India. Thus it looks at Sylhet's place as the producer of global commodity tea - interfacing capital and labour that left long-term impact. It explores how local people itself becoming global for seeking economic fortune. The dissertation further examines identity politics from 1870s to 1971 as these events shaped political mobilizations at home and abroad that ended up the creation of Bangladesh. The study begins in 1874, when Assam Province was created taking Sylhet from Bengal and ends in 1971, when Bangladesh emerged where Sylhetis played a key role at home and across the globe. The chapter one traces the distinctive nature of Sylhet as a frontier, a meeting point of cultures even before the opening of Sylhet for tea capitalism. Chapter two examines the local and overseas entrepreneurs involved in the development of the plantation. Chapter three focuses on the phenomenon of labour migration within the South Asian context created by the plantation, the recruitment of tea labourers from other regions up to 1000 kilometres away, some affected by famine and a sharp termination of the contacts with their homeland following the partition in 1947. Chapter four explores mobility of labour created by the merchant marine, drawing in Sylheti seafarers with a tradition of migration and involvement in water transport and taking them across the globe. It considers the impact of 1947 partition, cutting off Sylhetis from Calcutta and ships - out migration not only continues but become torrent. Chapter five goes on to examine social improvement through communication, education and public health. Chapter six looks at the political mobilization in Sylhet, the reaction of the Hindu elites to the prospect of decolonization and the displacement of this elite following partition in 1947 and trans-national network of Diaspora nationalism. The Sylhet referendum in 1947 emerged as a watershed needs emphasising more strongly as a structuring element in the overall study.

Full text
Abstract:
Research and debates on gender have shown in the past 20-30 years the importance of gender relations to the realisation or achievement of women's development or lack of advancement. This thesis addresses two major themes: firstly, it links a detailed study of intra-household social relations in rural household livelihood strategies; and secondly examines empirically the relationship between women's participation in Non-Wood Forest Product (NWFP), in this case murta (a herbaceous reed) production and processing; and the position and status of women as well as men within their households through gender analysis of rural livelihood strategies among poor households in one village, in Sylhet district, Bangladesh. Murta is one of the major income generating activities in which women in poorer households are engaged to meet their subsistence needs. The research used a qualitative case study approach to understand gender and household livelihood strategies among the poor. A gender analysis of the division of labour was made relating to assets, access and activities; the culturally contracted terms about the division of resources and the pattern of negotiations that take place between household members among selected cases. The second section of this thesis examines women's and men's status defined in the following terms: i) their control over resources; ii) their decision-making power within their households; iii) the recognition women receive for their work from household members and the village community; iv) culturally constructed rules about social status. This study shows that income contribution has not improved women's relative well-being. The study on social relations improves understanding of the household's livelihood strategies more holistically by recognising gender inequalities in resources and status through the terms of cultural rules and negotiations. This study concludes with suggestions for policy interventions as follows: in future the government and NGOs planning for gender and development programmes in rural livelihoods need to look beyond the roles to understand the cultural rules as status signifiers that are placed on how people construct their livelihoods; but planning also need to address the joint interests of negotiations over gender relations at household level.

Full text
Abstract:
Les nanoparticules d'argent sont de plus en plus utilisées dans les objets de consommation courante ainsi que dans les dispositifs médicaux pour leur activité biocide, qui est due au relargage d'ions Ag(I) au cours du temps. Le recul sur ces nano-objets et en particulier sur leur innocuité n'est toujours pas suffisant et les études sur leur transformation et leur impact in vivo sont sujets à d’intenses recherches. En effet, le devenir dans l’organisme des macro- et micro-matériaux étudiés classiquement n’est pas le même que celles des nanomatériaux. Les nanoparticules d’argent illustrent bien cette problématique : l’argent soluble injecté par voie intraveineuse est éliminé plus rapidement que la même quantité d’argent injectée sous forme nanoparticulaire. De plus, la concentration en argent retrouvée dans le sang et les organes est dix fois supérieure lorsque les nanoparticules d’argent sont injectées plutôt qu’ingérées. C'est pourquoi le développement de produits implantatoires qui se retrouvent donc en contact direct avec l’organisme, et qui contiennent des nanoparticules d’argent doit prendre en compte les risques associés, ce qui peut se faire par une approche Safer-by-design.Une des composantes principales du développement Safer-by-design concerne la fonctionnalisation des nano-objets. L’affinité des thiolates pour l’ion Ag(I) étant très forte, des ligands thiolés pourraient donc constituer une piste pour la fonctionnalisation des nanoparticules d’argent. Néanmoins, il est connu que les molécules thiolées conduisent à différents comportements allant de la dissolution de la nanoparticule d’argent en ions Ag(I) à la simple passivation de la surface de la nanoparticule ce qui peut entrainer la perte de son activité biocide.Ainsi, l’Ecoconception de Nouveaux Agents Biocides à base de Nanoparticules d’Argent à Enrobage Bio-inspiré avait pour objectif principal de poser les bases conceptuelles du développement d’un agent biocide Safer-by-design constitué de nanoparticules d’argent et de molécules thiolées en se positionnant à l’interface de plusieurs disciplines.Le développement de ce projet a nécessité d’étudier la réactivité de diverses molécules biologiques ou bio-inspirées thiolées avec les nanoparticules d’argent. Ainsi, nous avons mis en évidence l’importance de la pré-organisation architecturale des biomolécules dans la cinétique de dissolution, ainsi que le nombre de thiols libres dans la molécule. Dans le cas de composés induisant la dissolution des nanoparticules, sa cinétique augmente avec le nombre de thiols libres présents sur la molécule, et avec la pré-organisation du site de liaison du métal. Le projet principal de cette thèse a ensuite mené à la preuve de concept recherchée, avec le développement d’un nouvel agent biocide composé de nanoparticules d’argents pontées entre elles par un ligand thiolé tripode symétrique qui est le mime chimique d’un site de liaison d’une métallothionéine. Ces assemblages de nanoparticules se sont montrés actifs contre les bactéries (E. coli) et moins toxiques sur les cellules eucaryotes (HepG2), malgré une entrée dans les cellules similaire. Enfin, un criblage a également été réalisé avec des polyéthylèneglycols possédant un à huit thiols et des longueurs de polymères variables dans le but d’essayer de rationaliser les différences de comportement des nanoparticules d’argent en présence des molécules thiolées. Ce travail, a conduit à l’observation des comportements très variés qui vont permettre d’explorer de nouvelles voies de développements de biocides à base d’assemblages de nanoparticules médiés par des liaisons thiol – Ag(I).L’ensemble de ce travail de thèse a donc permis à la fois un travail très fondamental sur la réactivité des thiols vis-à-vis des atomes d’argent à la surface des nanoparticules et au développement de produits à potentiel applicatif, les assemblages de nanoparticules d’argent qui sont des biocides Safer-by-design<br>Silver nanoparticles are increasingly used in everyday consumer goods as well as in medical devices for their biocidal activity, which is due to the release of Ag(I) ions over time. The hindsight on these nano-objects and, in particular, on their safety is still not sufficient and studies on their transformation and their impact in vivo is currently an intense research field. Indeed, the fate in the body of macro- and micro-materials studied classically is not the same as for nanomaterials. The case of the silver nanoparticles illustrates this problem: the soluble silver injected intravenously is eliminated faster than the same amount of silver injected in nanoparticular form. Moreover, the concentration of silver found in the bloodstream and organs is ten times higher when silver nanoparticles are injected rather than ingested. The development of silver nanoparticle-containing implanted devices, that get in direct contact with the body, must thus take into account the related risks. A Safer-by-design approach could be a way to solve this issue.One of the main components of Safer-by-design development is the functionalization of nano-objects. The affinity of the thiolates for Ag(I) ions is very high, which would make thiolated ligands a good tool for silver nanoparticle functionalization. However, it is known that the thiolated molecules lead to different behaviors, ranging from the dissolution of silver nanoparticles into Ag(I) ions to the simple passivation of the surface of the nanoparticles, which leads to the loss of their biocidal activity.The Ecodesign of New Biocidal Agents based on Silver Nanoparticles and Bio-inspired Coating is therefore at the interface of several research areas and its main objective was to lay the conceptual foundations for the development of a Safer-by-design biocidal agent based on the interaction between silver nanoparticles and thiolated molecules.The development of this project required to study the reactivity of various biological or bio-inspired thiolated molecules with silver nanoparticles. First of all, we have highlighted the importance of the architectural pre-organization of biomolecules in the dissolution kinetics, as well as the role of the number of free thiols in the molecule. In the case of molecules inducing the dissolution of the nanoparticles, its kinetics increases with the number of free thiols present on the molecule and with the pre-organization of the metal binding site. In a second time, the main project of this thesis was the development of a proof of concept of a new biocidal agent composed of silver nanoparticles bridged together via a thiolated ligand, which is the chemical mimic of one binding site of a metallothionein. These nanoparticle assemblies were active against bacteria (E. coli) and less toxic than silver nanoparticles on eukaryote cells (HepG2), despite a similar cellular entry. Finally, a screening was performed with polyethylene glycols having two to eight thiols and varying polymer lengths in an attempt to rationalize the differences in the behavior of silver nanoparticles in the presence of the thiolated molecules. This ongoing work leads to various behaviors that will enable to explore novel ways for the development of biocidal based on nanoparticles assemblies mediated by thiol – Ag(I) bonds.Therefore, this overall PhD work allows performing both very fundamental researches concerning the reactivity of thiols with surface silver atoms of the nanoparticles and the development of products with application potential, silver nanoparticle assemblies that are Safer-by-design biocide

Abstract:
This thesis explores the utility of Attachment Theory (Bowlby, 1969; 1973; 1980) as a framework for understanding both the personality and cognitive processing styles associated with depression and vulnerability to depression. In two separate but related studies, the present investigation identified depressive personality characteristics and depressive cognitive processing styles associated with each of the styles of adult attachment defined by Bartholomew and Horowitz's (1991) four-category attachment model. Using self-report data from a sample of 305 respondents (225 female; 80 male), Study 1 explored associations among each of the adult attachment styles and sociotropic and autonomous personality-based vulnerabilities to depression (Beck, 1983). Extending the work of Zuroff and Fitzpatrick (1995; Study 2), associations among the attachment styles and the specific components of the two depressive personality styles, as defined by Robins et al. (1994), were examined. Using cued recall of autobiographical memories for a subsample of 44 of the same respondents (35 female; 9 male), Study 2 explored attachment style group differences in autobiographical memory retrieval, thereby identifying specific depressive cognitive processing biases associated with each adult attachment style. Past research has focused on the assessment of memory accessibility, using either recall latency (Mikulincer & Orbach, 1995; Mikulincer, 1998a) or memory generality (Tasker, MacLeod & Maynard, 1996) to indicate accessibility. In the present study, both latency and generality were used as indicators of memory accessibility, and the content of memories was also examined. In addition, use of a four-category rather than a three-category measure of attachment style permitted distinction of cognitive biases for the fearful-avoidant and dismissive-avoidant styles. The present findings support a notion that the two adult attachment styles understood to be characterised by a negative self-view, namely fearful and preoccupied attachment, are associated with depressive vulnerability. Replicating previous findings (Carnelley, Pietromonaco & Jaffe, 1994), both the fearful and preoccupied styles were associated with state depression and with perceptions of negative parental bonding. The fearful style in particular was associated with perceptions of 'affectionless control' in childhood. As the major focus of this thesis, the fearful and preoccupied attachment styles were each associated with both personality styles and cognitive processing deficits which have previously been linked with depression and depressive vulnerability. In terms of personality styles (Study I), the fearful attachment style was broadly associated with the autonomous personality style, whereas the preoccupied attachment style was broadly associated with the sociotropic personality style, as previously demonstrated by Zuroff and Fitzpatrick (1995; Study 2). By focusing on associations with the individual components of the autonomous and sociotropic vulnerabilities, as defined by Robins et al. (1994), the more specific 'depressive' personality characteristics were identified for both these insecure attachment styles. In particular, the findings suggest that a fearful attachment style involves both avoidant and self-critical characteristics, whereas a preoccupied attachment style involves both dependent and self-critical characteristics. In terms of cognitive processing deficits (Study 2), fearful individuals had difficulty accessing autobiographical memories, indicated by delayed memory recall and reduced memory specificity across a range of memory cues. Indeed, these individuals demonstrated a globalised 'mnemonic interlock' typical of depressed individuals (Williams, 1996) and their memories were predominantly negative in content. In contrast, preoccupied individuals demonstrated a ruminative cognitive processing style, indicated by relatively fast recall of predominantly specific and negative memories across a range of memory cues. However, these individuals had difficulty accessing personally-relevant memories of abandonment, arguably due to both encoding and retrieval deficits emanating from their hypersensitivity to abandonment experiences. Dismissive attachment was associated with the avoidant but not the self-critical aspect of the autonomous personality style and involved a repressive cognitive processing style. This repressive style was indicated by delayed recall of specific negative memories. Nonetheless, unlike the fearful and preoccupied styles, dismissive attachment was not shown to be associated with state depression, suggesting that an avoidant attachment style does not necessarily contribute to depressive vulnerability. Instead, dismissive individuals' use of defensive repression of negative affects and memories appears to be an effective coping mechanism in the maintenance of a positive self-concept and a non-self-critical approach. Furthermore, in light of self-narrative models of personality (e.g., McAdams, 1993; Bruhn, 1990; 1992; 1995; Singer & Salovey, 1993), dismissive individuals' easy access to positive memories, particularly personally-relevant memories of independence, can be viewed as maintaining their positive self-concept. Overall, the findings of the present thesis support the proposition that Attachment Theory provides a framework for understanding both the personality and cognitive processing styles associated with depression. Indeed, the findings suggest that the fearful and preoccupied adult attachment styles can both be regarded as constituting vulnerability factors for depression. As expected, the fearful attachment style was highlighted as conferring greater depressive vulnerability. Thus, the findings provide further insight into the factors involved in the onset and maintenance of depression and highlight the importance of assessing adult attachment style during therapy for depression. Other clinical implications, as well as directions for future research, are outlined.

Ce mémoire est une étude traductologique du suédois au français, concernant les mots inventés par Astrid Lindgren dans Ronya fille de brigand et spécifiquement les invectives, les jurons et les êtres (personnages inventés). Nous avons étudié les stratégies utilisées par la traductrice (selon Vinay et Darbelnet), la proximité avec la langue source ou la langue cible et le problème spécifique de traduire un livre pour la jeunesse du suédois au français. Notre conclusion est que les stratégies sont parfois difficiles à cerner mais que ce sont surtout des stratégies indirectes, que le texte est proche de la langue cible et qu’il y a un remplacement des mots inventés par des mots courants de la langue cible. Notre conclusion est que s’il n’existe pas une express ion identique dans la langue cible, il est probable que le traducteur remplace l’expression en question par une expression courante.<br>This essay is a translation study from Swedish to French concerning the invented words by Astrid Lindgren in Ronia, the Robber’s Daughter, in particular the swear words, invectives and spirits (invented figures). Our study examines the strategies used by the translator according to Vinay and Darbelnet, the closeness to the source language or the target language and the specific problems when translating a book for children from Swedish to French. Our conclusion is that the strategies sometimes are difficult to encircle and that the indirect strategies are more frequent. We noticed also that the text, concerning these words, is closer to the target language and that there is a replacement of the invented words of more standard words in the target language. Our conclusion is that if it does not exist an identical expression in the target language, it is likely that the translator replaces this expression with a more common one.

Abstract:
Eighty-seven high school students completed a modified version of the Organizational Communication Conflict Instrument: 38 students had behavioral problems and 49 didn't. Result indicate that all these students use significantly more control strategies than solution-orientation or non-confrontation strategies to resolve conflicts with their peers. T-tests identified several significant differences ($\alpha$ = 0.05): (1) boys with behavioral problems use significantly less non-confrontation strategies than boys without behavioral problems; (2) girls with behavioral problems use significantly less solution-orientation strategies than girls without behavioral problems; (3) boys with behavioral problems use significantly more solution-orientation strategies than girls with behavioral problems. Furthermore, although only significant at $\alpha$ = 0.07, boys with behavioral problems belonging to non-nuclear families use control strategies more than boys from nuclear families. These findings show however that all high school students could benefit from conflict resolution programs.

Abstract:
Les sprites sont de gigantesques phénomènes lumineux qui sont produits entre 40 et 90 km d’altitude généralement par des éclairs nuage-sol positifs. Les sprites sont des phénomènes très brefs (durée de quelques millisecondes) qui appartiennent à la famille des TLEs (évènements lumineux transitoires) et qui sont composés de structures filamentaires nommées streamers. Les streamers sont des filaments de plasma, qui se propagent à des vitesses allant jusqu’à ∼10⁷ m/s et qui possèdent des champs électriques très forts souvent proches de 150 kV/cm (champs réduit à la pression atmosphérique). Lors de ce travail, on a développé un modèle fluide de plasma qui simule les décharges streamers couplées avec un modèle simulant les émissions optiques afin d’étudier la physique des streamers, des TLEs et plus particulièrement des sprites dans le cadre de la mission spatiale TARANIS. Cette mission a pour objectif d’étudier le système Atmosphère-Ionosphère-Magnétosphère, et observera les TLEs et leurs émissions associées: électromagnétiques, optiques, et probablement radiations énergétiques depuis le nadir. Dans cette thèse, on propose d’étudier certains problèmes liés aux streamers et aux sprites qui sont cruciaux pour préparer la mission TARANIS. Plus particulièrement nous abordons certains mécanismes de production de radiations énergétiques par les streamers récemment proposés dans la littérature et nous développons une méthode qui permet de déterminer l’altitude, la vitesse et le champ électrique des streamers des sprites, à partir d’une analyse spectroscopique de leurs émissions optiques. Nos résultats renforceront donc le retour scientifique des futures missions spatiales observant les TLE depuis le nadir et particulièrement TARANIS<br>Sprites are large optical phenomena usually produced between 40 and 90 km altitude generally by positive cloud-to-ground lightning (+CG). These are short lifetime phenomena (duration of few milliseconds) that belong to the family of transient luminous events (TLEs) and composed of complex filamentary structures called streamers. Streamers are non-thermal plasma filament, highly collisional, propagating with velocities up to 10⁷ m/s, and characterized with high electric fields at their heads often close to 150 kV/cm when scaled to ground level air. In this work, we have developed a streamer plasma fluid model coupled with an optical emission model to investigate the physics of streamers and sprites in the framework of the TARANIS space mission. TARANIS will observe TLEs from a nadir-viewing geometry along with their related emissions (electromagnetic and particles). In this dissertation, we investigate some mechanisms of emission of energetic radiation from streamers recently proposed in the literature and we present an original spectroscopic method to determine sprite streamers altitudes, velocities, and electric fields through their optical emissions. This method is especially useful for increasing the scientific return of space missions that have adopted nadir-based observation strategies

Abstract:
La méiofaune joue un rôle important dans le fonctionnement des habitats benthiques à substrat meuble (ex. flux de matière) en relation avec sa production élevée, sa position trophique intermédiaire et les importants transferts d’énergie vers les niveaux trophiques supérieurs qui y sont lié. Les relations trophiques et les flux de matière organique liés à la méiofaune restent néanmoins mal connus ou peu pris en compte. Afin de mieux appréhender le rôle de la méiofaune, la structure des communautés et les relations trophiques entre les sources de nourriture et ces consommateurs ont été déterminées dans cinq habitats à substrat meuble (i.e., vasière nue, herbier, zone à sables) de la baie de Marennes-Oléron, France, et de la baie de Sylt-Rømø, Allemagne, en tenant compte des variations temporelles. Le peuplement de méiofaune s’est trouvé être dominé par les nématodes et les copépodes benthiques. Les biomasses de microphytobenthos et de matière organique du sédiment sont apparues comme étant deux facteurs structurants pour les communautés. L’utilisation combinée de différents traceurs de la matière (i.e., isotopes stables, acides gras) a démontré que le microphytobenthos et les bactéries étaient les ressources trophiques majeures de la méiofaune dans les cinq habitats étudiés. Les mesures réalisées sur la structure des communautés et les données issues des traceurs de la matière ont été implémentées dans des modèles de réseaux trophiques. Dans tous les habitats, ces modèles ont mis en évidence que le flux de carbone dominant était issu du microphytobenthos, ceci démontrant les très faibles changements de comportements alimentaires malgré les importantes différences de sources trophiques en termes de disponibilité et de production des sources de nourriture entre ces différents habitats. Tous les groupes trophiques de nématodes, à l’exception des déposivores sélectifs, étaient particulièrement sélectifs et s’alimentaient majoritairement à partir de microphytobenthos, ceci étant à l’origine d’une forte production et d’un court temps de renouvellement de la méiofaune. En conclusion, cette thèse démontre le rôle important de la méiofaune dans les habitats à substrat meuble ainsi que l’importance de la relation trophique entre le microphytobenthos et la méiofaune dans le fonctionnement de ces réseaux trophiques<br>Meiofauna play an important role in ecosystem processes in soft-bottom benthic habitats, e.g. food web dynamics, related to their highproduction, their intermediate trophic position and the energy they transfer towards higher trophic levels. The trophic linkages and flows of organic matter related to the meiofauna remain poorly known or taken into account. To better assess the role of meiofauna, the community structure and trophic relationships between food sources and meiofauna were determined in five intertidal soft-bottom habitats (i.e., mudflat, seagrass bed, sandflat) of the Marennes-Oléron Bay, France, and the Sylt-Rømø Bight, Germany, taking temporal variations into account. Meiofauna communities were dominated by nematodes and benthic copepods. Biomass of microphytobenthos and of sediment organic matter were two of the major drivers of community structure. The combination of trophic markers (i.e., stable isotopes, fatty acids) demonstrated that microphytobenthos and bacteria were the major food sources of meiofauna in the five habitats. Information from community structure assessments and trophic marker analyses were implemented in food web models. In all habitats, these models demonstrated that the main flow of carbon to meiofauna originated from microphytobenthos, highlighting negligible changes in meiofauna feeding behavior besides the large differences in availability and productivity of food sources between these habitats. All trophic groups of nematodes, except for selective deposit feeding nematodes, were highly selective and mainly fed on microphytobenthos, resulting in a high production and a short turn-over time of meiofauna. In conclusion, this thesis demonstrated the important role of meiofauna in soft-bottom habitats as well as the importance of the trophic pathway from microphytobenthos to meiofauna in the functioning of these food webs
