De l’aller-retour au point de non-retour : Étude comparative de l’expérience interculturelle et du sentiment d’épuisement culturel des expatriés occidentaux en Inde

Afin de saisir le contexte du phénomène de l’expatriation d’Occidentaux en Inde, nous relevons d’abord certains traits de la modernité occidentale, tels le sentiment d’aliénation, le tournant subjectiviste, la globalisation et les principaux mythes-modèles de l’Inde qui circulent dans les pays occidentaux et donnent naissance aux projets d’expatriation. Une approche expérientielle facilite la compréhension de l’expatriation telle qu’elle est vécue par les acteurs. La collecte de données ethnographiques permet de saisir ces expériences à partir de récits recueillis dans trois zones frontière : 1) à Rishikesh, auprès d’expatriés spirituels; 2) à Calcutta, auprès d’expatriés humanitaires; 3) à Goa, auprès d’expatriés hédonistes-expressifs cherchant à améliorer leur style de vie. Ces données ethnographiques sont présentées dans trois chapitres distincts. Un chapitre comparatif met ensuite en relief quelques points de convergence dans l’expérience des expatriés, soit l’insertion locale au sein de communautés spécifiques, fortement associées à des mythes-modèles de l’Inde; le renouveau identitaire découlant de l’expérience interculturelle; et finalement, l’impact du transnationalisme sur la consolidation du malaise face à la modernité. La discussion théorique présente les solutions mises en branle par les expatriés pour tempérer leur malaise par rapport à l’Occident, soit : 1) l’engagement en profondeur dans un mode de vie permettant de se réaliser selon ses propres aspirations; 2) le regroupement par affinités et l’adoption d’un rôle social clair; 3) l’affranchissement de la pression sociale et l’adoption de pratiques transnationales permettant de préserver une continuité affective avec les proches tout en endossant un statut d’étranger. L’étude révèle aussi qu’on ne peut faire abstraction de l’histoire des relations de l’Occident avec le sous-continent pour comprendre les relations interculturelles des expatriés occidentaux avec les Indiens locaux. Enfin, les privilèges socioéconomiques des Occidentaux en Inde sont clairement identifiés comme étant une condition essentielle de leurs projets d’expatriation, ceux-ci étant néanmoins motivés principalement par un sentiment d’épuisement culturel face à l’Occident et à son mode de vie. Faisant suite à l’analyse des points de vue critiques sur la modernité (renforcés par l’expérience d’altérité), la thèse s’achève sur l’évocation de quelques pistes de recherche pour une anthropologie de l’Occident, tout en interrogeant, implicitement, le projet anthropologique.

California pragmatista 1900-1960: proyecto doméstico como expresión y laboratorio del modo de vida

Esta tesis doctoral pretende desgranar una técnica de proyecto que la experiencia californiana ejemplifica y que puede ser descrita en términos pragmatistas. La arquitectura doméstica californiana fue la expresión tangible de una forma de ser y estar californiana pero también universal. El destinatario de esta arquitectura experimental y pragmática fue el individuo, tanto el gran mecenas como el liberal individualista de recursos moderados y aspiraciones infinitas; la gente corriente y, más tarde, la típica familia de clase media, fueron sin embargo el destinatario soñado en muchos ensayos de casa particular, frecuentemente en la casa del propio arquitecto. Arquitectos y clientes compartían el deseo común de un espacio doméstico involucrado en propiciar una vida sana, informal y hedonista, y en comunión con el aire, la naturaleza y el territorio, que satisficiera el espíritu independiente y emprendedor propio de una identidad libre y progresista. Participaron en ese sentido de la esperanza pragmatista de un futuro mejor, mediante la formulación de un modo de vida propio, moldeado por las distintas fuerzas motoras que definían el contexto. La principal de ellas fue la sensación de oportunidad: California se ofrecía como una tabula rasa con un clima paradisíaco; el paraíso soñado para generaciones sucesivas de recién llegados, que en la distancia con tradiciones preestablecidas en sus lugares de origen, encontraron el mayor estímulo para una actitud experimental que tomó el modo de vida como un material de proyecto para la formulación del espacio doméstico. Así, el proyecto doméstico californiano, fue un laboratorio cuyo trabajo mezclaba casos específicos con mitos e ilusiones, muchas veces cuestionadas; pero su interés reside en que puede ser, además de un referente estético y un icono visual, un ejemplo de una forma de proyectar que aborda el proyecto doméstico con talante indagador desde la receptividad al contexto físico, social y cultural; con capacidad para soñar y experimentar llevando los ideales a la práctica de los casos concretos; desde la atención al usuario, aunque sea anónimo; y usando un léxico llano, que devuelve toda la eficacia al vocabulario cotidiano. La experiencia californiana es por tanto, en este trabajo, sólo un ejemplo; un ejemplo paradigmático de una técnica de proyecto que puede ser de interés en otras circunstancias y contextos, y que concibe el espacio doméstico como la expresión, y también el laboratorio, del modo de vida. ABSTRACT This doctoral thesis aims to display a design’s technic that is exemplified by the Californian experience and can be described in pragmatic terms. The Californian domestic architecture was the tangible expression of a life style and way of being that was Californian but also universal. Home’s designed for the everyday experience attended the individual, both the rich sponsors of their own domestic design and the low income liberal individualists in search of an affordable but optimum home. But the dreamed target was ordinary people and the typical middle class family, as they represented the dream of a truly democratic society. Many domestic experiments for them took the form of particular cases, often in the house of the architect, which acted as a laboratory in search of general solutions. Architects and clients shared the common desire of a new domestic space, involved in promoting a healthy, casual and hedonistic lifestyle and in communion with the air, nature and territory, which satisfied the own independent and entrepreneurial spirit of a free and progressive identity. The way of life was therefore a design material, sensitive to the forces that shaped the region and its society through its domestic space. The main one was the feeling of opportunity: California offered itself as a tabula rasa with an exotic climate; the dreamed paradise for successive generations of newcomers who, in the distance with the pre-established traditions of their homelands, found the greatest incentive for an experimental attitude in which lifestyle was seen as project material to formulate the domestic space. Thus, the Californian domestic project can be more than an aesthetic reference and a visual icon; it is also an example of a design’s technic that approaches the domestic project with an inquisitive spirit sustained by these abilities: receptivity to the physical, social and cultural context; capacity to dream and to experiment, carrying ideals into practice; attention to the user, even when it’s anonymous; and use of a common lexicon that returns all the power to the everyday vocabulary. The Californian experience is therefore, in this dissertation, just an example; a paradigmatic example of a project technique that conceives domestic space as an expression, and also as a laboratory, of the way of life.

Exploratory Study Of The Effect Of Lifestyle Counselling On Bone Mineral Density And Body Composition In Users Of The Contraceptive Depot-medroxyprogesterone Acetate.

To compare variations in bone mineral density (BMD) and body composition (BC) in depot-medroxyprogesterone acetate (DMPA) users and nonusers after providing counselling on healthy lifestyle habits. An exploratory study in which women aged 18 to 40 years participated: 29 new DMPA users and 25 new non-hormonal contraceptive users. All participants were advised on healthy lifestyle habits: sun exposure, walking and calcium intake. BMD and BC were assessed at baseline and 12 months later. Statistical analysis included the Mann-Whitney test or Student's t-test followed by multiple linear regression analysis. Compared to the controls, DMPA users had lower BMD at vertebrae L1 and L4 after 12 months of use. They also had a mean increase of 2 kg in total fat mass and an increase of 2.2% in body fat compared to the non-hormonal contraceptive users. BMD loss at L1 was less pronounced in DMPA users with a calcium intake ≥ 1 g/day compared to DMPA users with a lower calcium intake. DMPA use was apparently associated with lower BMD and an increase in fat mass at 12 months of use. Calcium intake ≥ 1 g/day attenuates BMD loss in DMPA users. Counselling on healthy lifestyle habits failed to achieve its aims.

Explaining sleep duration in adolescents: the impact of socio-demographic and lifestyle factors and working status

Previous studies found students who both work and attend school undergo a partial sleep deprivation that accumulates across the week. The aim of the present study was to obtain information using a questionnaire on a number of variables (e.g., socio-demographics, lifestyle, work timing, and sleep-wake habits) considered to impact on sleep duration of working (n=51) and non-working (n=41) high-school students aged 14-21 yrs old attending evening classes (19:00-22:30 h) at a public school in the city of So Paulo, Brazil. Data were collected for working days and days off. Multiple linear regression analyses were performed to assess the factors associated with sleep duration on weekdays and weekends. Work, sex, age, smoking, consumption of alcohol and caffeine, and physical activity were considered control variables. Significant predictors of sleep duration were: work (p < 0.01), daily work duration (8-10 h/day; p < 0.01), sex (p=0.04), age 18-21 yrs (0.01), smoking (p=0.02) and drinking habits (p=0.03), irregular physical exercise (p < 0.01), ease of falling asleep (p=0.04), and the sleep-wake cycle variables of napping (p < 0.01), nocturnal awakenings (p < 0.01), and mid-sleep regularity (p < 0.01). The results confirm the hypotheses that young students who work and attend school showed a reduction in night-time sleep duration. Sleep deprivation across the week, particularly in students working 8-10 h/day, is manifested through a sleep rebound (i.e., extended sleep duration) on Saturdays. However, the different roles played by socio-demographic and lifestyle variables have proven to be factors that intervene with nocturnal sleep duration. ) The variables related to the sleep-wake cycle naps and night awakenings proved to be associated with a slight reduction in night-time sleep, while regularity in sleep and wake-up schedules was shown to be associated with more extended sleep duration, with a distinct expression along the week and the weekend. Having to attend school and work, coupled with other socio-demographic and lifestyle factors, creates an unfavorable scenario for satisfactory sleep duration

Wolbachia genomes: insights into an intracellular lifestyle

The genome sequence of the Wolbachia endosymbiont that infects the nematode Brugia malayi has recently been determined together with three partial Wolbachia genomes from different Drosophila species. These data along with the previously published Wolbachia genome from Drosophila melanogaster provide new insights into how this endosymbiont has managed to become so successful.

TP53 and EGFR mutations in combination with lifestyle risk factors in tumours of the upper aerodigestive tract from South America

Cancers of the upper aerodigestive tract [(UADT): oral cavity, pharynx, larynx and oesophagus] have high incidence rates in some parts of South America. Alterations in the TP53 gene are common in these cancers. In our study, we have estimated the prevalence and patterns of TP53 mutations (exons 4-10) in 236 UADT tumours from South America in relation to lifestyle risk factors, such as tobacco smoking and alcohol drinking. Moreover, we have conducted a pilot study of EGFR mutations (exons 18-21) in 45 tumours from the same population. TP53 mutation prevalence was high: 59% of tumours were found to carry mutant TP53. We found an association between TP53 mutations and tobacco smoking and alcohol drinking. The mutation rate increased from 38% in never-smokers to 66% in current smokers (P-value for trend = 0.09). G:C > T:A transversions were found only in smokers (15%). Alcohol drinkers carried more G:C > A:T transitions (P = 0.08). Non-exposed individuals were more probable to carry G:C > A:T transitions at CpG sites (P = 0.01 for never-smokers and P < 0.001 for never-drinkers). EGFR mutations were found in 4% of cases. Inactivation of TP53 by mutations is a crucial molecular event in the UADT carcinogenesis and it is closely related to exposure to lifestyle risk factors. EGFR mutations do not appear to be a common event in UADT carcinogenesis in this population.

Diet, lifestyle and the risk of Type 2 Diabetes Mellitus in women

Background Previous studies have examined individual dietary and lifestyle factors in relation to type 2 diabetes, but the combined effects of these factors are largely unknown. Methods We followed 84,941 female nurses from 1980 to 1996; these women were free of diagnosed cardiovascular disease, diabetes, and cancer at base line. Information about their diet and lifestyle was updated periodically. A low-risk group was defined according to a combination of five variables: a body-mass index (the weight in kilograms divided by the square of the height in meters) of less than 25; a diet high in cereal fiber and polyunsaturated fat and low in trans fat and glycemic load (which reflects the effect of diet on the blood glucose level); engagement in moderate-to-vigorous physical activity for at least half an hour per day; no current smoking; and the consumption of an average of at least half a drink of an alcoholic beverage per day. Results During 16 years of follow-up, we documented 3300 new cases of type 2 diabetes. Overweight or obesity was the single most important predictor of diabetes. Lack of exercise, a poor diet, current smoking, and abstinence from alcohol use were all associated with a significantly increased risk of diabetes, even after adjustment for the body-mass index. As compared with the rest of the cohort, women in the low-risk group (3.4 percent of the women) had a relative risk of diabetes of 0.09 (95 percent confidence interval, 0.05 to 0.17). A total of 91 percent of the cases of diabetes in this cohort (95 percent confidence interval, 83 to 95 percent) could be attributed to habits and forms of behavior that did not conform to the low-risk pattern. Conclusions Our findings support the hypothesis that the majority of cases of type 2 diabetes could be prevented by the adoption of a healthier lifestyle.
