MIROIRS : l’identité et l’intimité sexuelle chez les femmes ayant vécu l’expérience de l’ablation d’un sein

Dans la société occidentale le corps et les seins ont été investis au fil des siècles. Selon le sociologue Amadieu, «le poids des apparences» est de plus en plus prégnant. Qu’arrive-t-il lorsqu’une femme reçoit le diagnostic d’un cancer du sein, doublé par l’annonce de l’ablation de celui-ci? C’est la perte de références. Il y aura désormais un avant et un après. Dans sa trajectoire de maladie, la femme ayant eu une mastectomie recevra de nombreuses images dans le Miroir par le biais de son propre regard, de celui de son partenaire sexuel et de celui des autres femmes. La première image est celle d’une femme mutilée. Cette altération corporelle a conduit certaines à un questionnement profond à l’égard de leur «entièreté d’être femme» et, corrélativement, à leur capacité de séduction. Notre recherche a permis de retracer les images/conceptions qui surgissent dans les nombreux Miroirs de l’identité et de l’intimité sexuelle et d’identifier des stratégies visant une réappropriation bio/socio/symbolique de leur «être femme».

Macro-geographical differences influenced by family-based expression on cultured pearl grade, shape and colour in the black-lip "pearl oyster" Pinctada margaritifera: a preliminary bi-local case study in French Polynesia

In French Polynesia, the aquaculture of P. margaritifera is carried out in numerous grow-out sites, located over three archipelagos (Gambier, Society and Tuamotu). To evaluate the impact of macro-geographical effects of these growing sites on pearl quality traits, five hatcheries produced families were used as homogeneous donor oysters in an experimental graft. The molluscs were then reared in two commercial locations: Tahaa island (Society) and Rangiroa atoll (Tuamotu). At harvest, eight pearl quality traits were recorded and compared: surface defects, lustre, grade, circles, shape categories, darkness level, body and secondary colour and visual colour categories. Overall inter-site comparison revealed that: 1) all traits were affected by grow-out location except for lustre and round shape, and 2) a higher mean rate of valuable pearls was produced in Rangiroa. Indeed, for pearl grade, Rangiroa showed twice as many A-B and less reject samples than Tahaa. This was related to the number of surface defects (grade component): in Rangiroa, twice as many pearls had no defects and less pearls had up to 10 defects. Concerning pearl shape, more circled and baroque pearls were found in Tahaa (+10%). For colour variation, 10% more pearls have an attractive green overtone in Rangiroa than in Tahaa, where more grey bodycolor were harvested. Lustre does not seem to be affected by these two culture site (except at a family scale). This is the first time P. margaritifera donor family have been shown to vary in the quality of pearls they produce depending on their grow-out location.

Age-dependence of cultured pearl grade and colour in the black-lipped pearl oyster Pinctada margaritifera

Pinctada margaritifera is an economically important marine bivalve species for cultured pearl production in French Polynesian aquaculture. In order to evaluate the influence of donor oyster age on pearl quality traits, experiments were conducted over 6 years using both grafts and surgreffe operations. At harvest, 6 pearl quality traits were recorded and compared: surface defects, luster, grade, darkness level, and visual color. Analyzing the quality traits of pearls harvested in the initial graft process and those of pearls obtained from surgreffe experiments allowed a comparison of the influence of pearl sac cells originating from the initial mantle graft, which aged together with their recipient oysters. The results demonstrated a significant decrease between these successive grafts in luster, grade (A-B-C,) darkness level, and green color – traits that are of major importance in the pearl market. The duplicated graft experiment allowed the comparison of donor oyster families at 2 and 5 years old, where a mantle graft was inserted into recipient oysters aged 2.5 years old. The results showed the same tendencies to a lesser extent, with 1) an improved pearl grade, predominantly through a most important rate of 0 surface defect category, and 2) a green / grey ratio in favor of the younger donor. A comparison between the graft-surgreffe and the duplicated graft experiments also highlighted: 1) the indirect role played by the younger recipient oysters, which must be optimized for optimal pearl quality realization, and 2) the complex interplay between donor and recipient oysters.

Protein feeding of Queensland fruit fly Bactrocera tryoni and cucumber fly Zeugodacus cucumis (Diptera: Tephritidae) on non-host vegetation: effect of plant species and bait height

Perimeter-baiting of non-crop vegetation using toxic protein baits was developed overseas as a technique for control of melon fly, Zeugodacus (Zeugodacus) cucurbitae (Coquillett) (formerly Bactrocera (Zeugodacus) cucurbitae), and evidence suggests that this technique may also be effective in Australia for control of local fruit fly species in vegetable crops. Using field cage trials and laboratory reared flies, primary data were generated to support this approach by testing fruit flies' feeding response to protein when applied to eight plant species (forage sorghum, grain sorghum, sweet corn, sugarcane, eggplant, cassava, lilly pilly and orange jessamine) and applied at three heights (1, 1.5 and 2 m). When compared across the plants, Queensland fruit fly, Bactrocera tryoni (Froggatt), most commonly fed on protein bait applied to sugarcane and cassava, whereas more cucumber fly, Zeugodacus (Austrodacus) cucumis (French) (formerly Bactrocera (Austrodacus) cucumis), fed on bait applied to sweet corn and forage sorghum. When protein bait was applied at different heights, B. tryoni responded most to bait placed in the upper part of the plants (2 m), whereas Z. cucumis preferred bait placed lower on the plants (1 and 1.5 m). These results have implications for optimal placement of protein bait for best practice control of fruit flies in vegetable crops and suggest that the two species exhibit different foraging behaviours.

L’influence de l’aménagement linguistique sur l'orientation des travaux de terminologie à l’Office québécois de la langue française (1961-2004)

La terminologie, telle quelle se pratique au Québec depuis une cinquantaine d'années, s'inscrit dans un projet d'aménagement linguistique qui vise à faire du français la langue d'utilisation commune sur le territoire québécois. La mise en œuvre de ce projet a été confiée à l'Office québécois de la langue française. Dans le cadre de la présente thèse, nous évaluons l'influence de l'aménagement linguistique sur l'orientation des travaux de terminologie à l'Office québécois de la langue française de 1961 à 2004. Notre objectif principal est de montrer que le projet d'aménagement linguistique a engendré une intense activité terminologique à la suite de l'adoption de diverses lois linguistiques au cours des cinquante dernières années. Plus précisément, nous analysons l'impact de ces lois sur le développement de la pratique de la terminologie. Pour ce faire, nous avons proposé six périodes qui caractérisent les travaux de terminologie de l'Office québécois de la langue française de 1961 à 2004. À l'intérieur de ces six périodes, nous analysons les mandats que les lois linguistiques ont confiés à l'Office et leurs répercussions sur l'orientation de ses travaux terminologiques. À l'instar de la problématique que nous avons esquissée au début de cette thèse, les résultats de notre recherche révèlent que la pratique de la terminologie est liée au projet de société que le Québec s'est donné pour assurer la défense du français sur son territoire. En outre, l'adoption des lois linguistiques a favorisé le développement de la pratique de la terminologie. Cette pratique a évolué en fonction des différents mandats confiés à l'Office québécois de la langue française qui a mis au point une méthodologie de travail en terminologie. C'est dans le cadre de l'aménagement linguistique que la terminologie s'est développée au Québec et qu'elle est devenue l'instrument clé de la mise en œuvre du projet d'aménagement linguistique québécois.

Construção e validação de uma escala multi-factorial de motivação no trabalho (mult-moti)

Esta investigação tem como objectivo a construção e validação de uma Escala MultiFactorial de Motivação no Trabalho para a população portuguesa. A ausência de instrumentos para medir várias dimensões da motivação levou ao desenvolvimento e elaboração desta escala de motivação. A escala integra 28 itens decorrentes de uma pesquisa teórica que contempla algumas teorias da motivação. Participaram nos estudos de validação da escala 444 colaboradores de empresas de novas tecnologias de ambos os sexos, com idades compreendidas entre os 19 e os 34 anos. A escala apresenta bons índices de consistência interna (valores entre 0.72 e 0.84) e uma análise factorial que revelou a existência de uma estrutura tetrafactorial com 49% de variância explicada: motivação com a organização do trabalho, motivação com realização e poder, motivação de desempenho e motivação associada ao envolvimento. Esperase ainda que novos estudos possam ser desenvolvidos a partir desta mesma escala.
