Abstract: In Imperial Eyes Mary Louise Pratt (1992: 7, emphasis original) defines autoethnography as "instances in which colonized subjects undertake to represent themselves in ways that engage with the colonizer's own terms ... in response to or in dialogue with . . . metropolitan representations." Although Pratt's conceptualization of autoethnography has much to offer post-colonial studies, it has received little attention in the field. In this thesis, I interrogate Pratt's notion of autoethnography as a theoretical tool for understanding the self-representations of subordinate peoples within transcultural terrains of signification. I argue that autoethnography is a concept that allows us to move beyond some theoretical dualisms, and to recognize the (necessary) coexistence of subordinate peoples' simultaneous accommodation of and resistance to dominant representations of themselves. I suggest that even when autoethnographic expressions seem to rely on or to reproduce dominant knowledges, their very existence as speech acts implicitly resists dominant discourses which objectify members of oppressed populations and re-create them as Native Informants. I use Pratt's concept to analyze two books by Islamic feminist sociologist Fatima Memissi. Memissi's Dreams ofTrespass and Scheherazade Goes West illustrate the simultaneity of accommodation and disruption evident in autoethnographic communication. Across the two books, Memissi shows herself renegotiating the discourses which discipline her (and her speech). She switches back and forth between the positions of reader and author, demonstrates the reciprocity of the disciplinary gaze (she looks back at her dominants, reading their own reading of her representation of her social group), and provides a model of autoethnographic dialogue.

This thesis examines Death of a Ghost (1934), Flowers for the Judge (1935), Dancers in Mourning (1937), and The Fashion in Shrouds (1938), a group of detective novels by Margery Allingham that are differentiated from her other work by their generic hybridity. The thesis argues that the hybrid nature of this group of Campion novels enabled a highly skilled and insightful writer such as Allingham to negotiate the contradictory notions about the place of women that characterized the 1930s, and that in dOing so, she revealed the potential of one of the most popular and accessible genres, the detective novel of manners, to engage its readers in a serious cultural dialogue. The thesis also suggests that there is a connection between Allingham's exploration of modernity and femininity within these four novels and her personal circumstances. This argument is predicated upon the assumption that during the interwar period in England several social and cultural attitudes converged to challenge long-held beliefs about gender roles and class structure; that the real impact of this convergence was felt during the 1930s by the generation that had come of age in the previous decade-Margery Allingham's generation; and that that generation's ambivalence and confusion were reflected in the popular fiction of the decade. These attitudes were those of twentieth-century modernity--contradiction, discontinuity, fragmentation, contingency-and in the context of this study they are incorporated in a literary hybrid. Allingham uses this combination of the classical detective story and the novel of manners to examine the notion of femininity by juxtaposing the narrative of a longstanding patriarchal and hierarchical culture, embodied in the image of the Angel in the House, with that of the relatively recent rights and freedoms represented by the New Woman of the late nineteenth-century. Pierre Bourdieu's theory of social difference forms the theoretical foundation of the thesis's argument that through these conflicting narratives, as well as through the lives of her female characters, Allingham questioned the Hsocial myth" of the time, a prevailing view that, since the First World War, attitudes toward the appropriate role and sphere of women had changed.

My approach to the vampire detective highlights its connections to the private detective's story and reveals the monstrous investigators' debt to early feminist forms of detection -specifically in their reformation of the' other' and of traditional forms of power and authority. Seen in this light the movement of horror's imaginary 'other' into the rational world of detection can be seen as not an abrupt breach of detection's realist conventions, but an almost seamless transition into symbolic spaces that point to the detective's primary function -- to make sense of the senseless. It is in this light that I explore the monster that is a detective as a symbol that is also a sense-maker, and a quintessential postmodern figure. I argue that the distinctions between monsters and 'others', and between popular narratives and postmodern religion have faded, culminating in a character that can not only model 'otherness' as an exemplary condition, but also provide strategies for modeling the form of active postmodern subjectivity that postmodern theorist Jim Collins' (1989) conceives of as heretical activity.

In this thesis, I critically examine the discourses that inform how we conceptualise HIV/AIDS in Sub-Saharan Africa as they are produced in a sample of Canadian news articles, two nonfiction texts - Stephanie Nolen's 28 Stories of AIDS in Africa and Jonathan Morgan and the Bambanani Women's Group's Long Life ... Positive HIV Stories - as well as two literary texts - John Le Carre's popular fiction novel The Constant Gardener and an anthology of stories and poems from Southern Africa titled Nobody Ever Said AIDS, compiled and edited by Nobantu Rasebotsa, Meg Samuelson and Kylie Thomas. Paying particular attention to the role of metaphor in discursive formation, I have found that military metaphors, usually used in conjunction with biomedical discourses, continue to dominate what is said about HIV/AIDS. However, the use of military metaphors to conceptualise HIV/AIDS contributes to stigma and limits the effectiveness of responses to the pandemic. I argue that accessing alternative metaphors and discourses, such as biopsychosocial discourse, can lead to a more layered - and more beneficial - conceptualisation of HIV/AIDS, encouraging a more active response to the pandemic.

The freshwater mollusc Lymnaea stagnalis was utilized in this study to further the understanding of how network properties change as a result of associative learning, and to determine whether or not this plasticity is dependent on previous experience during development. The respiratory and neural correlates of operant conditioning were first determined in normally reared Lymnaea. The same procedure was then applied to differentially reared Lymnaea, that is, animals that had never experienced aerial respiration during their development. The aim was to determine whether these animals would demonstrate the same responses to the training paradigm. In normally reared animals, a behavioural reduction in aerial respiration was accompanied by numerous changes within the neural network. Specifically, I provide evidence of changes at the level of the respiratory central pattern generator and the motor output. In the differentially reared animals, there was little behavioural data to suggest learning and memory. There were, however, significant differences in the network parameters, similar to those observed in normally reared animals. This demonstrated an effect of operant conditioning on differentially reared animals. In this thesis, I have identified additional correlates of operant conditioning in normally reared animals and provide evidence of associative learning in differentially reared animals. I conclude plasticity is not dependent on previous experience, but is rather ontogenetically programmed within the neural network.

The relationship between photoperiod, plasma concentration of ionic calcium and the histology of the prolactin-secreting cells of the rostral pars distalis of the pituitary gland, the Corpuscles of Stannius and the Ultimobranchial gland were investigated. Neither the plasma concentration of ionic calcium nor histologically apparent prolactin cell activity could be correlated with photoperiod. Some evidence of a photoperiodic effect on both the Corpuscles of Stannius and the Ultimobranchial gland was obtained. The expected reciprocal relationship between the activity of these glands was not obvious at the histological level . Quantitative and qualitative analysis at the light microscope level revealed, however, that the hormone prolactin-secreting eta cells of the rostral pars distalis and the hypocalcin-secreting cells of the Corpuscles of Stannius may be arranged in a lamellar pattern comprized of synchronous bands of cells in like-phase of a secretory cycle consisting of four stages - synthesis, storage, release and reorganization. Such synchronized cell cycles in these glands have not heretofore been described in literature. It is suggested that the maintenance of at least 255? of the cells in any one phase of the cycle ensures a supply of the required hormone at all times.

Sherlock Holmes has been one of the most-adapted characters in literature since his first appearance in A Study in Scarlet in Beeton's Christmas Annual in 1887. Each new adaptation must offer innovations that bring freshness and contemporary appeal to time-worn stories and concepts or risk irrelevancy; analyzing these changes closely sheds light on shifts in societal constructs. Taking this as a starting point, this thesis examines Sherlock and Elementary from a perspective of feminism and queer theory via methods of discourse and genre analyses, with texts ranging from 1931 to the present as objects of comparison. The research illuminates constructions of masculinity as they have changed over time, particularly the movement from an orderly, stable, rational construction of hegemonic masculinity to one that is chaotic, often violent, and anti-heroic in at least some aspects while still being invested in the status quo.

Cette thèse explore le leitmotiv de la prostitution dans l’oeuvre de Tennessee Williams et soutient que la plupart des personnages de Williams sont engagés dans une forme de prostitution ou une autre. En effectuant une analyse formaliste des textes de Williams qui illustrent toute forme de prostitution, avec une attention particulière à quatre grandes pièces, A Streetcar Named Desire (1947), Cat on a Hot Tin Roof (1955), Suddenly Last Summer (1958) et Sweet Bird of Youth (1959), cette présente étude fait valoir que le dramaturge utilise un mode de fiction—le gothique—en lien avec une pratique transgressive—la prostitution—pour relier les classes sociales et troubler les catégories de prostitution. Ce faisant, Williams offre une vision plus représentative et nuancée de la prostitution. Théoriquement, cette thèse repose sur des oeuvres critiques portant sur le genre, la sexualité et l'histoire de Michel Foucault, David Savran, et Michael Paller afin de situer la dramaturgie de Williams dans le contexte historique et culturel des années 1940 et 1950. La première partie de cette thèse (chapitres un et deux) fournit de nombreuses informations autobiographiques et biographiques qui expliquent pourquoi la prostitution est devenue le thème de prédilection pour Williams. Cette section met l’accent sur sa préoccupation constante à l’égard de sa prostitution artistique (en prostituant son art pour le succès commercial) et sexuelle (en payant pour des prostitués). Cette partie présente également un inventaire détaillé des prostituté(e)s, que je divise en trois catégories: 1) la prostitution des enfants, 2) la prostitution masculine et 3) la prostitution féminine. La deuxième partie de cette étude, composée des chapitres trois et quatre, identifie les personnages de Williams qui s’engagent dans une forme de prostitution morale. Ce groupe comprend ceux qui tirent directement profit de la prostitution des autres ainsi que ceux qui se marient uniquement pour un gain financier ou une promotion sociale ou les deux. L’oeuvre de Williams résiste la représentation stéréotypée de la prostituée en littérature comme étant uniquement de sexe féminin ou provenant des classes sociales défavorisées ou les deux. La prostituée de Williams n’est ni une figure romantique ni une rebelle menaçant la société. Cette thèse conclut qu’en représentant des enfants prostitués, des femmes de rue, des prostitués de sexe masculin, des souteneurs, des proxénètes, des propriétaires de bordels, des leaders corrompus et des personnes qui se prostituent en concluant des mariages de convenance, Williams a effectivement et incontestablement dramatisé la prostitution sous toutes ses formes.

Le benzo-a-pyrène (BaP) est un cancérogène reconnu pour l'homme, contaminant présent dans notre environnement. Il cause des dommages à l'ADN que nous avons mesurés dans les lymphocytes exposés à de faibles concentrations de BaP, provenant de 20 jeunes volontaires non fumeurs et en santé. Suite à l’exposition, la fréquence des micronoyaux (MN) augmente significativement et décrit une courbe dose-réponse non linéaire, suggérant le déclenchement du processus de détoxification et la réparation de l’ADN. Des différences entre les individus et entre les sexes sont présentes dans la réponse génotoxique produite par le BaP. Le test des aberrations chromosomiques montre que le pourcentage de chromosomes cassés augmente significativement dans les cellules exposées au BaP. Combinés avec l'augmentation de la fréquence des MN, nos résultats confirment l'effet clastogène du BaP déjà rapporté dans la littérature. L’hybridation in situ en fluorescence (FISH) des MN avec une sonde pancentromérique est aussi utilisée pour établir leur mécanisme de formation. La FISH révèle que la majorité des MN formés après une exposition au BaP contient un centromère et plus, ce qui est significativement différent de la condition non exposée. Plus précisément, dans nos conditions expérimentales, les MN induits par le BaP contiennent surtout trois centromères et plus, indiquant également la présence d'un effet aneugène. L'effet clastogène du BaP est relié à son rôle d'initiateur dans la cancérogenèse, alors que l'effet aneugène le relierait à l'étape de progression. Ces résultats sont importants puisque l'exposition aux composés de la classe du BaP est de longue durée (cigarette, air pollué).

Les tumeurs des cellules de la granulosa (GCTs) sont des tumeurs avec un potentiel malin ayant tendance à récidiver, provoquant ainsi la mort dans 80% des cas de stade avancé consécutif à une rechute. Bien que les GCTs représentent 5% des tumeurs ovariennes, peu d’études ont évalué les protocoles de traitement adjuvant pour la maladie avancée ou récurrente. Notre but était d’évaluer l’efficacité de la voie de signalisation du facteur de croissance de l’endothélium vasculaire A (VEGFA) comme cible pour le traitement de la GCT utilisant le modèle murin transgénique Ptentm1Hwu/tm1Hwu; Ctnnb1tm1Mmt/+; Amhr2tm3(cre)Bhr/+ (PCA) qui reproduit le stade avancé de la maladie humaine. Un anticorps anti-VEGFA a été administré une fois par semaine par voie intrapéritonéale (IP) à partir de 3 semaines d’âge. La thérapie anti-VEGFA a permis une réduction de la taille des tumeurs à 6 semaines d’âge (p<0.05) et une prolongation de la survie des animaux traités, lorsque comparé aux animaux contrôles. L’analyse des GCTs a montré une réduction significative de la prolifération cellulaire (p<0.05) et de la densité microvasculaire (p<0.01) mais aucune différence significative n’a été détectée dans l’apoptose cellulaire. p44/p42 MAPK, un effecteur de la signalisation pour le récepteur 2 de VEGFA (VEGFR2) associé à la prolifération cellulaire, était moins activé dans les tumeurs traitées (p<0.05). Par contre, l’activation d’AKT, un effecteur impliqué dans la survie cellulaire, était similaire d’un groupe à l’autre. Ces résultats suggèrent que l’anticorps anti-VEGFA réduit la prolifération cellulaire et la densité microvasculaire chez les souris PCA par inhibition de la voie de signalisation VEGFR2-MAPK, inhibant ainsi la croissance tumorale. En conclusion, l’efficacité de la thérapie anti- VEGFA mérite d’être évaluée en essais contrôlés randomisés pour le traitement des GCTs chez l’homme.

Cette thèse présente une revue des réflexions récentes et plus traditionnelles provenant de la théorie des systèmes, de la créativité en emploi, des théories d’organisation du travail et de la motivation afin de proposer une perspective psychologique de la régulation des actions des individus au sein d’environnements de travail complexes et incertains. Des composantes de la Théorie de la Régulation de l’Action (Frese & Zapf, 1994) ainsi que de la Théorie de l’Auto-Détermination (Deci & Ryan, 2000) sont mises en relation afin d’évaluer un modèle définissant certains schémas cognitifs clés associés aux tâches individuelles et collectives en emploi. Nous proposons que ces schémas cognitifs, organisés de manière hiérarchique, jouent un rôle central dans la régulation d’une action efficace au sein d’un système social adaptatif. Nos mesures de ces schémas cognitifs sont basées sur des échelles de mesure proposées dans le cadre des recherches sur l’ambiguïté de rôle (eg. Sawyer, 1992; Breaugh & Colihan, 1994) et sont mis en relation avec des mesures de satisfaction des besoins psychologiques (Van den Broeck, Vansteenkiste, De Witte, Soenens & Lens, 2009) et du bien-être psychologique (Goldberg, 1972). Des données provenant de 153 employés à temps plein d’une compagnie de jeu vidéo ont été récoltées à travers deux temps de mesure. Les résultats révèlent que différents types de schémas cognitifs associés aux tâches individuelles et collectives sont liés à la satisfaction de différents types de besoin psychologiques et que ces derniers sont eux-mêmes liés au bien-être psychologique. Les résultats supportent également l’hypothèse d’une organisation hiérarchique des schémas cognitifs sur la base de leur niveau d’abstraction et de leur proximité avec l’exécution concrète de l’action. Ces résultats permettent de fournir une explication initiale au processus par lequel les différents types de schémas cognitifs développés en emplois et influencé par l’environnement de travail sont associés à l’attitude des employés et à leur bien-être psychologique. Les implications pratiques et théoriques pour la motivation, l’apprentissage, l’habilitation, le bien-être psychologique et l’organisation du travail dans les environnements de travail complexes et incertains sont discutés.

This dissertation examines gendered fictional dialogue in popular works by D.H. Lawrence, Ernest Hemingway and E.M. Forster, including Howards End (1910), The Sun Also Rises (1926) and Lady Chatterley’s Lover (1928). I apply Judith Halberstam’s notion of female masculinity to direct speech, to explore how speech traits inform modernist literary aesthetics. My introduction frames this discussion in sociolinguistics, Judith Butler’s theory of performativity, M.M. Bakhtin’s discourse theory, and gender studies. It provides an opportunity to establish experimental dialogue techniques, and the manipulation of gendered talk, in transgressive texts including James Joyce’s Ulysses (1922), Virginia Woolf’s Orlando (1928) and Radcyffe Hall’s The Well of Loneliness (1928). The first chapter discusses taboos and dialect in D.H. Lawrence’s fictional dialogue. The second chapter establishes gender subversion as a crucial element in Ernest Hemingway’s dialogue style. The third chapter contrasts Forster’s latently gendered speech with his techniques of dialect emphasis and dialect suppression. Finally, my conclusion discusses gender identity in the poetry of Dorothy Parker and Baroness Elsa von Freytag Loringhoven, and the temporality of gender in “Time Passes” from Virginia Woolf’s To the Lighthouse (1927). New Woman characters like Lady Brett Ashley typified a crucial moment in women’s liberation. They not only subverted stereotypes of womanhood through their dress or sexual freedom, they also adopted/adapted masculine idiom to shock, to rebel against and challenge male dominance. Different speech acts incited fashionable slang, became a political protest symbol or inspired psychoanalytic theory. The intriguing functions of women’s masculine speech in early twentieth century fiction establishes the need to examine additional connections between gender and talk in literary studies.

In this thesis we have studied a few models involving self-generation of priorities. Priority queues have been extensively discussed in literature. However, these are situations involving priority assigned to (or possessed by) customers at the time of their arrival. Nevertheless, customers generating into priority is a common phenomena. Such situations especially arise at a physicians clinic, aircrafts hovering over airport running out of fuel but waiting for clearance to land and in several communication systems. Quantification of these are very little seen in literature except for those cited in some of the work indicated in the introduction. Our attempt is to quantify a few of such problems. In doing so, we have also generalized the classical priority queues by introducing priority generation ( going to higher priorities and during waiting). Systematically we have proceeded from single server queue to multi server queue. We also introduced customers with repeated attempts (retrial) generating priorities. All models that were analyzed in this thesis involve nonpreemptive service. Since the models are not analytically tractable, a large number of numerical illustrations were produced in each chapter to get a feel about the working of the systems.

The world demand for fish and fishery products is increasing steadily and it is generally accepted that it will not be possible to meet the heavy demand with resources exploited from capture fishery alone. Now aquaculture is well established and fastdeveloping industry in many countries and is a major focus sector for development. During recent decades, aquaculture has gained momentum, throughout the world especially in developing countries. According to Food and Agricultural Oganisation (FAO, 2000), global aquaculture production was 26.38 tones in 1996 have reached 32.9 million tonnes during 1999. Only marine aquaculture sector has contributed 13.1 million tonnes during 1999.India is a major fish producing country. About one half of lndia’s brackish water lands are currently being utilized for farming in order to reduce the gap between supply and demand for fish. Aquaculture has become a major source of livelihood for people and its role in integrated rural development, generation of employment and earning foreign exchange, thereby alleviating poverty is being greatly appreciated around the world.Among the infectious agents, bacteria are becoming the prime causal organisms for diseases in food fishes and other marine animals. Sindermann, (1970) reported that bacterial fish pathogen most commonly found among marine fishes is species of Pseudomonas, Vibrio and Mycobacterium. These can be categorized into primary pathogens; secondary invaders that may cause systemic disease in immunocompromised hosts; and normal marine flora which are not pathogenic but may occur on body surfaces or even within the tissues of the host. I-Iigh density of animals in hatchery tanks and ponds is conducive to the spread of pathogen and the aquatic environment with regular application of protein rich feed, is ideal for culturing bacteria. Bacteria, which are normally present in seawater or on the surface of fish, can invade and cause pathological effects in fishes, which are injured or subjected to other environmental stresses.Mycobacteria except parasites are known as nontuberculosis mycobacteria (NTM), atypical mycobacteria or mycobacteria other than tuberculosis(MO'l'l"). This group of mycobacteria includes opportunistic pathogens and saprophytes. Environmental mycobacteria are ubiquitous in distribution and the sources may include soil, water, warm-blooded as well as cold-blooded animals. Disease caused by environmental mycobacterial strains in susceptible humans (Goslee & Wolinsky, 1976; Grange, 1987), animals and fishes are increasingly attracting attention. Greatest importance of environmental mycobacteria is believed to be their role in immunological priming of humans and animals, thereby modifying their immune responses to subsequent exposure to pathogenic species.
