Secretory immunity in overweight and obese versus normal-weight early-and late-pubertal females

Obesity is a condition associated with a wide variety of health problems including hypertension, dyslipidemia, diabetes mellitus, certain forms of cancer, cardiovascular disease, and gallstones (157). TTiere is growing evidence that obesity may also be related to compromised immune function due to altered metabolic, psychological, and physical attributes (93). The aim of this study was to compare: a) immunity-related variables such as frequency of upper respiratory tract infections (URTI) and salivary secretory immunoglobulin A (sIgA) levels between overweight/obese (OB) and normal weight (NW) early-pubertal and late-pubertal girls, and b) stress-related variables such as Cortisol, melatonin, the melatonin/cortisol ratio, testosterone and the testosterone/cortisol ratio. Physical activity levels, stress indicators, and fatigue were used to explain potential differences in the dependent variables. It was hypothesized that the OB females would have lower melatonin (M) and higher Cortisol (C) and testosterone (T) levels compared with NW girls, regardless of maturity status. The altered levels of melatonin, Cortisol, and testosterone, would result in decreased M/C and T/C ratios, despite the increase in testosterone in OB females. It was hypothesized that this altered hormonal status results in a compromised immunity marked by higher frequency of upper respiratory tract infections (URTI) and decreased levels of secretory immunoglobulin A (sIgA). It was also hypothesized that OB girls would participate in less hours of physical activity than their NW counterparts and that this would relate to their stress and immunity levels. Forty (16 early- and 24 late-pubertal) overweight and obese females were compared to fifty-three (27 eariy- and 26 late-pubertal) age-matched normal-weight control subjects. Participants were categorized as early-pubertal (EP) or late-pubertal (LP) using Tanner self-staging of secondary sex characteristics. Subjects were classified into the two adiposity groups according to relative body fat (%BF), where normal weight (NW) subjects had a %BF less than 25%, and overweight and obese (OB) subjects had a %BF greater than 27.5%. Participants completed a number of questionnaires and information was collected on menstrual history, smoking history, alcohol and caffeine consumption, and medical history. Following the determination of maturity status, a complete anthropometric assessment was made including height, body mass, and body composition. All questionnaires and measurements were completed during a one-hour visit between 1 500 and 1900 hours Relative body fat was assessed using bioelectrical impedance analysis. Resting saliva samples were obtained and assayed (ELISA) for testosterone, Cortisol, melatonin and secretory immunoglobulin A. Physical activity was self-reported using the Godin- Shephard Leisure time questionnaire, and quantified using Actigraph GTIM accelerometers, which participants wore for seven consecutive days from the time they woke up in the morning, until the time they went to bed. Late-pubertal girls also completed questionnaires on their perceived stress and fatigue. Finally, all participants also filled out a one-month health log to record frequency of symptoms of upper respiratory tract infections (URTI). Significant age effects were found for testosterone, Cortisol, incidence of sickness, and sIgA when controlling for physical activity, however there were no significant effects of adiposity on any of the variables. There was a trend which neared-significance for an effect of adiposity on sIgA (p=0.01). There were no significant differences between the groups on the total selfreported leisure-time physical activity in METs per week, however EP girls recorded significantly greater levels of moderate, hard, and very hard physical activity from accelerometers. Results of the perceived stress and fatigue questionnaires in late-pubertal girls demonstrated that contrary to what was hypothesized, NW girls reported more stress and more fatigue than OB girls. Results of the present study suggest that excess adiposity in early- and latepubescent girls may not have a negative impact on immunity as hypothesized.

An exploration of transformation theory and the western tradition: a critical evaluation of a graduate studies class

This qualitative study is an exploration of transformation theory, the Western tradition, and a critical evaluation of a graduate studies class at a university. It is an exploration of assumptions that are embedded in experience, that influence the experience and provide meaning about the experience. An attempt has been made to identify assumptions that are embedded in Western experience and connect them with assumptions that shape the graduate class experience. The focus is on assumptions that facilitate and impede large group discussions. Jungian psychology of personality type and archetype and developmental psychology is used to analyze the group experience. The pragmatic problem solving model, developed by Knoop, is used to guide thinking about the Western tradition. It is used to guide the analysis, synthesis and writing of the experience of the graduate studies class members. A search through Western history, philosophy. and science revealed assumptions about the nature of truth, reality, and the self. Assumptions embedded in Western thinking about the subject-object relationship, unity and diversity are made explicit. An attempt is made to identify Western tradition assumptions underlying transformation theory. The critical evaluation of the graduate studies class experience focuses upon issues associated with group process, self-directed learning, the educator-learner transaction and the definition of adult education. The advantages of making implicit assumptions explicit is explored.

Ethnic conflicts and international politics : an analysis of the communal regional, and global dimensions of the Cyprus problem

The thesis assesses the impact of international factors on relations between Greek and Turkish Cypriots during and after the Cold War. Through an analysis of the Cyprus problem it explores both why external actors intervene in communal conflicts and how they influence relations between ethnic groups in plural societies. The analytical framework employed throughout the study draws on contributions of International Relations theorists and students of ethnic conflict. The thesis argues that, as in the global political system, relations between ethnic groups in unranked communal systems are anarchic; that is, actors within the system do not recognize a sovereign political authority. In bipolar communal systems dominated by two relatively equal groups, the struggle for security and power often leads to appeals for assistance from external actors. The framework notes that neighboring states and Great Powers may heed calls for assistance, or intervene without a prior request, if it is in their interest to do so. The convergence of regional and global interests in communal affairs exacerbates ethnic conflicts and precludes the development of effective political institutions. The impact of external intervention in ethnic conflicts has the potential to alter the basis of communal relations. The Cyprus problem is examined both during and after the Cold War in order to gauge how global and regional actors and the structure of their respective systems have affected relations between ethnic groups in Cyprus. The thesis argues that Cyprus's descent into civil war in 1963 was due in part to the entrenchment of external interests in the Republic's constitution. The study also notes that power politics involving the United States, Soviet Union, Greece and Turkey continued to affect the development of communal relations throughout the 1960s, 70s, and, 80s. External intervention culminated in July and August 1974, after a Greek sponsored coup was answered by Turkey's invasion and partition of Cyprus. The forced expulsion of Greek Cypriots from the island's northern territories led to the establishment of ethnically homogeneous zones, thus altering the context of communal relations dramatically. The study also examines the role of the United Nations in Cyprus, noting that its failure to settle the dispute was due in large part to a lack of cooperation from Turkey, and the United States' and Soviet Union's acceptance of the status quo following the 1974 invasion and partition of the island. The thesis argues that the deterioration of Greek-Turkish relations in the post-Cold War era has made a solution to the dispute unlikely for the time being. Barring any dramatic changes in relations between communal and regional antagonists, relations between Greek and Turkish Cypriots will continue to develop along the lines established in July/August 1974. The thesis concludes by affirming the validity of its core hypotheses through a brief survey of recent works touching on international politics and ethnic conflict. Questions requiring further research are noted as are elements of the study that require further refinement.

Explaining the Great Divergence: Medium and Message on the Eurasian Land Mass, 1700-1850

Between 1700 and 1850, per-capita income doubled in Europe while falling in the rest of Eurasia. Neither geography nor economic institutions can explain this sudden divergence. Here the consequences of differences in communications technology are examined. For the first time, there appeared in Europe a combination of a standardized medium (national vernaculars with a phonetic alphabet) and a non-standardized message (competing religious, political and scientific ideas). The result was an unprecedented fall in the cost of combining ideas and burst of productivity-raising innovation. Elsewhere, decreasing standardization of the medium and increasing standardization of the message blocked innovation.

Postcolonial readings of resistance and negotiation in selected contemporary African writing

Cette dissertation traite des (re)configurations postcoloniales de la résistance et de la négociation comme concepts permettant d’aborder les représentations des conflits nationaux dans les littératures Africaines contemporaines. Ensemble, ces concepts ouvrent de nouvelles voix et possibilités de se remémorer, de raconter, et de lire la violence en problématisant non seulement les discours sur la guerre civile en Afrique, mais aussi les conceptions d’histoire nationale, de la mémoire, et de leur représentation. Si cette étude cherche à reconfigurer la négociation et la résistance au-delà des définitions qui tendent à les opposer, elle se consacre surtout à développer la notion de négociation comme stratégie de dépassement, de lecture, et d’écriture, qui, néanmoins, ne vise pas de résolution. La négociation implique ainsi une conception pluraliste d’un pouvoir d’action sociale, politique, et culturelle. Cette dissertation avance que la négociation est un concept d’écriture et de lecture qui intervient dans les événements, discours, et pratiques de remémoration en prenant compte de leurs multiplicités et définitions instables. Cette étude explore les manières selon lesquelles Nuruddin Farah, Chenjerai Hove, Yvonne Vera, Chimamanda Adichie, et Sefi Atta déploient la négociation et la résistance comme outils d’engagement esthétique et sociopolitique dans la narration de la violence en Somalie, au Zimbabwe, et au Nigeria. En outre, la négociation marque mon analyse de l’intervention des textes dans les discours d’historiographie et de représentation. Si ces romans mettent en exergue la généalogie complexe du conflit postcolonial, ils négocient aussi les implications multiples, incluant la leur, dans les questions problématiques de la responsabilité et de la représentation. La vii négociation représente un acte conscient à travers lequel nous reconnaissons l’instabilité de toute bataille politique, morale, ou éthique sans pour autant céder à un cynisme paralysant. De par son approche négociée et interdisciplinaire, cette dissertation ne fait pas qu’entrer en débat avec des discours multiples des études postcoloniales, Africaines, et littéraires. Elle intervient aussi dans les conceptions de la nation, la violence, la mémoire, la responsabilité, et la justice selon les études philosophiques, politiques, et culturelles. Outre les critiques littéraires, les chapitres interrogent les théories de penseurs tels Ngugi wa Thiong’o, David Jefferess, Pheng Cheah, et Wole Soyinka. Cette approche éclectique reflète l’attention des romans à la complexité irréductible des responsabilités individuelles et collectives dans les récits d’histoire et d’appartenance nationales. Cet engagement négocié avec les questions entourant la postcolonialité, malgré la dominance actuelle des discours de la globalisation, permet de reconceptualiser l’approche postcoloniale pour contrer les analyses déhistorisées et décontextualisées des conflits sociopolitiques en Afrique. Le chapitre 1 élabore les concepts clés de la dissertation. Le chapitre 2 explore la résistance et la négociation dans le langage figuré métonymique dans les représentations de la guerre en Somalie. Le chapitre 3 se consacre à l’analyse de la figure de la spectralité dans la narration de l’histoire et de la violence nationales au Zimbabwe. Finalement, le chapitre 4 négocie les concepts de représentation et de responsabilité dans les récits du trauma postcolonial au Nigeria. viii Mots-clés : négociation, résistance, littératures africaines, violence, responsabilité, nation, représentation

Understanding the past to imagine the future : the history of industrial design practice in Alberta

La pratique du design industriel dans la province canadienne de l’Alberta est en pleine croissance. Ses activités sont principalement concentrées à Edmonton et à Calgary, qui sont les plus grandes villes de la province. On y trouve des studios de design de renom, des communautés de design complexes et des programmes universitaires de design bien établis. Cependant, la pratique du design industriel albertaine est sous-développée en comparaison avec celle du reste du Canada et il y a peu de recherches et de documentation sur le design industriel en Alberta. Dans ce projet de mémoire, la pratique du design industriel en Alberta a été explorée depuis une approche historique. Pour pallier le manque de documentation, la collecte de données a été faite par une recherche qualitative, des entretiens narratifs et une recherche quantitative statistique. Une base d’information historique sur le design industriel albertain a été établie puis située par rapport au développement de la pratique du design industriel ailleurs au Canada. Les facteurs, événements et tendances dans l’histoire de la pratique du design industriel en Alberta ont été identifiés. De plus, le développement de la pratique du design industriel de l’Alberta a été comparé à celui du Québec et de l’Ontario. Les retombées de cette étude indiquent que la pratique du design industriel en Alberta présente quatre domaines de spécialisations distincts se développant depuis les années 1980. La pratique du design industriel en Alberta est sous-développée en comparaison à celui du Québec et de l’Ontario, mais elle peut devenir plus compétitive, au niveau canadien, avec plus de soutien gouvernemental, de meilleures relations avec l’industrie manufacturière et les institutions académiques, une communauté de design plus unifiée et en portant une plus grande attention aux domaines les plus prometteurs de l’industrie. Ces informations supportent une meilleure compréhension de la pratique du design industriel en Alberta et pourront informer les praticiens, enseignants et administrateurs du domaine du design industriel dans la province. Finalement, le mémoire servira de base à d’autres projets de recherche sur les changements potentiels dans la pratique du design industriel en Alberta et l’étude du design canadien et des industries de design régionales.

L’élargissement de l’Union européenne dans un contexte de sécurisation croissante des migrations:enjeux et conséquences pour les nouveaux membres de l’Est

"En mai 2004, l’Union européenne connaissait un élargissement sans précédent, passant soudainement de 15 à 24 pays membres. Cet élargissement s’est opéré dans un contexte mondial marqué par une sécurisation accrue des migrations ; une tendance à laquelle l’Union Européenne ne saurait échapper. Cet élargissement constitue, aujourd’hui encore, un défi fondamental pour l’UE qui d’un côté craint pour sa sécurité en multipliant les politiques restrictives à l’endroit des migrations et qui, de l’autre, se doit d’intégrer ces dix nouveaux membres, pour la plupart issus de l’ancien bloc soviétique et n’ayant par conséquent que très peu d’expériences et de moyens en matière de contrôle migratoire ; ce domaine ayant été pendant plus de 60 ans l’apanage du pouvoir central de Moscou. Le défi à relever est d’autant plus grand si l’on considère le fait que ces nouveaux membres se situent géographiquement aux frontières centrales et orientales de l’Europe et en constituent ainsi l’une des plus importantes portes d’entrées. En imposant à ces nouveaux membres la reprise intégrale de l’acquis communautaire, sans tenir compte des spécificités géographiques, historiques, économiques et politiques de ces pays, l’Union européenne risque de payer le prix d’une politique hypocrite et aveugle et de favoriser la multiplication d’effets pervers, pouvant aller jusqu’à compromettre, à terme, la stabilité de la région."

Bionomics, cryopreservation of gametes and captive breeding behaviour of threatened hillstream cyprinid, garra surendranathanii(shaji, arun & easa, 1996)

Garra surendranathanii is a hill stream cyprinid endemic to Kerala. According to IUCN based classification, G. surendranathanii is grouped under the threatened category. This endemic fish is having highly restricted and fragmented distribution and reported only from 5 river systems viz. Chalakudy, Periyar, Pamba, Achenkoil and Bharathapuzha. Categorization of this fish as a potential ornamental candidate can invariably add more pressure on the threat status of this particular species. Hence, this species is considered as one which requires foremost attention for conservation. Hitherto, no infomiation is available on the bionomics, resource characteristics and any conservation attempts of G. surendranathanii. Studies on detailed life history traits and development of captive breeding technique are indispensable for successful fishery management.The present study was undertaken with the following obj ectives: To study the Length-weight relationship and condition factor to ascertain the relationship between length and weight and general wellbeing ofthe fish To study the age and growth to understand the age composition of the exploited stock, age at first maturation and life span of the species. To study the reproductive biology of G. surendranathanii to gain insights in the process of gametogenesis, spawning, sex ratio, fecundity and other related aspects which are essential for developing captive breeding technology of this species. To develop captive breeding technology and cryopreservation ofgametes of G. surendranathanii for conservation

Continuation and discontinuation of local institution in community based natural resource management

Currently the push toward frontier areas, which until twenty years ago were still largely untouched by commercial agriculture, is taking place on a massive scale. This push is being driven not the least by global economic developments, such as the price increase of agriculture commodities like coffee and cocoa. In most cases the indigenous communities become trapped between the state monopoly in natural resource management and the competition for resources by external actors. In this processes the indigenous communities start to lose their access to resources. Another victim in this process is the environment where the natural resources are imbedded. International and national organizations working to conserve environment have became conscious of the important role that indigenous people could fulfill as partners in this endeavour. This partnership in struggle has produced a new discourse on the relationship between indigenous people and their environment. As a further consequence, programs were set up to develop what became known as Community Based Natural Resource Management (CBNRM) with its numerous variations. Based on a case study in a village on the eastern border of the Lore Lindu National Park in Central Sulawesi, this study questioned the basic assumption behind the concept of Community Based Natural Resource Management (CBNRM). Namely the assumption that communities living at the margin of forest are socially and culturally homogenous, still more or less egalitarian, and basically living in harmony with their natural environment. This study was inspired by the persistent critique – although still a minority – on the basic assumption the CBNRM from academicians and practitioners working through the Entitlement perspective. Another inspiration was the mounting critique toward the participatory approach. In its effort the study explore further the usefulness of certain approaches. One of the approach much relied on in this study was the local history of the community studied, through exerting oral and local written documents on local history, legends and local stories. These sources proofed quite capable in bringing the local history into the light. Another was the actor oriented approach, which later came to be supported by the concept of Social Pool Resources. The latter concept proofed to be useful as analytical instrument to integrate social institutions and the common pool resources, as a field of action for the different actors as human agencies.

La cooperación cultural como herramienta para la reafirmación identitaria en el Grupo Visegrád y sus efectos en el posicionamiento del mismo dentro de la Unión Europea 2004-2012

El Grupo Visegrád es un escenario de cooperación multilateral, conformado por Polonia, República Checa, Eslovaquia y Hungría, el cual tiene como objetivo principal contribuir al cumplimiento de los intereses de dichos países, por medio de la financiación de proyectos culturales. El interés de esta monografía consiste en determinar la incidencia de la cooperación cultural en la reafirmación identitaria de cada uno de los miembros del Grupo y, por ende, en la manera como éstos se proyectan dentro de la Unión Europea. Así pues, se identifican los principales hechos históricos que han moldeado los intereses de los países del V4 y que condujeron a la creación de una estructura institucional sólida, que ha servido como plataforma para el accionar de dichos países dentro del bloque europeo. Se utiliza la perspectiva constructivista de Alexander Wendt, la cual permite entender la naturaleza de la cooperación y, su relación con las identidades y los intereses de los Estados.

The Victoria Falls 1900-1940: Landscape, tourism and the geographical imagination

This article is about the politics of landscape ideas, and the relationship between landscape, identity and memory. It explores these themes through the history of the Victoria Falls, and the tourist resort that developed around the waterfall after 1900. Drawing on oral and archival sources, including popular natural history writing and tourist guides, it investigates African and European ideas about the waterfall, and the ways that these interacted and changed in the course of colonial appropriations of the Falls area. The tourist experience of the resort and the landscape ideas promoted through it were linked to Edwardian notions of Britishness and empire, ideas of whiteness and settler identities that transcended new colonial borders, and to the subject identities accommodated or excluded. Cultures of colonial authority did not develop by simply overriding local ideas, they involved fusions, exchanges and selective appropriations of them. The two main African groups I am concerned with here are the Leya, who lived in small groups around the Falls under a number of separate chiefs, and the powerful Lozi rulers, to whom they paid tribute in the nineteenth century. The article highlights colonial authorities' celebration of aspects of the Lozi aristocracy's relationship with the river, and their exclusion of the Leya people who had a longer and closer relationship with the waterfall. It also touches on the politics of recent attempts to reverse this exclusion, and the controversial rewriting of history this has involved.
