Au siècle des Lumières, les femmes sont exclues des principales professions médicales - à l'exception des sages-femmes - et leurs pratiques sont l'objet de nombreuses critiques de la part des médecins et chirurgiens qui promeuvent leurs propres connaissances sur le corps, soucieux d'acquérir un nouveau statut social, économique et politique. La médicalisation de la société ne se fait pas pour autant contre les femmes, car les plus aisées d'entre elles sont sollicitées comme médiatrices de la nouveauté. Dans ce contexte, cette thèse interroge la réception des ambitions médicales et la place prise par les femmes dans le processus de médicalisation. Les sources sollicitées ne sont pas celles qui sont produites par les soignants, afin de prendre de la distance avec leur discours normatif et professionnel, mais celles qui ressortent de l'intime : journaux et mémoires, correspondances et livres de raison, recueils de recettes féminins. Il s'agit ainsi de composer une histoire des souffrantes et des soignantes à partir de discours « de » femmes et non « sur » les femmes, à l'intersection de l'histoire socio¬culturelle de la médecine, de l'histoire des femmes et de celle du genre. Ceci limite l'analyse aux lettrées, membres de la noblesse ou de la haute bourgeoisie, française et helvétique en l'occurrence. Les savoirs féminins sont au coeur de l'analyse à travers la définition des lieux d'apprentissage du corps et des représentations corporelles que leurs écrits mettent en scène. Les pratiques de soin féminines sont également étudiées, en dissociant le soin de soi -incluant aussi bien l'automédication, le recours aux thérapeutes que l'influence de la parenté dans la gestion de la santé et de la maternité - du soin d'autrui qui se rapporte aux corps sur lesquels les femmes exercent leur pouvoir de soin et à leurs manières de soigner.

Le but de cette thèse est d'étudier l'impact d'une appartenance groupale jouissant d'un supérieur dans la hiérarchie sociale sur la volonté de participer à des actions collectives en faveur d'une appartenance groupale désavantagée. Selon la Théorie de l'Identité Sociale, les individus sont en effet membres de plusieurs groupes simultanément, qui constituent autant d'identités sociales potentielles. Comme l'ont montré les recherches en sociologie du genre s'inscrivant dans le courant intersectionnel, les diverses catégories sociales auxquelles une personne appartient peuvent se trouver dans des positions différentes dans la hiérarchie sociale, plaçant ainsi les individus à l'intersection de divers rapports de domination. Toutefois, ces rapports ne sont pas indépendants les uns des autres, mais interagissent et contribuent conjointement à construire une façon spécifique de vivre et de percevoir l'expérience de la domination. Globalement, notre thèse montre que lorsque deux endogroupes dotés de statuts différents sont simultanément saillants, les individus tendent à agir prioritairement en accord avec les intérêts de l'endogroupe dont le statut est le plus élevé, au détriment de l'endogroupe dont le statut est le plus bas : les individus tendent en effet à adhérer à des idéologies qui contribuent à légitimer le maintien des inégalités intergroupes, ce qui a pour conséquence de réduire leur volonté de participer à des actions collectives en faveur de leur endogroupe de statut inférieur. - This thesis focuses on the impact of a high status ingroup on willingness to participate in collective action in favour of a low status ingroup. According to Social Identity Theory, individuals are members of various groups, each of which is a potential social identity. Moreover, the feminist sociological theory of intersectionality suggests that these various ingroups can occupy different positions in social hierarchies, placing individuals at the intersection of various relations of domination. However, these relations do not act independently of one another, but interrelate, and shape a specific way to live and perceive the experiences of domination. On the whole, our thesis shows that when two ingroups with different statuses are salient, people tend to acts uppermost in compliance with the higher status group interest, to the detriment of the lower status group : Indeed, people tend to agree with ideologies that contribute to legitimate the perpetuation of intergroup inequalities. Consequently their willingness to participate in collective action in favor of their low-status group is reduced.

Esta dissertação teve como ponto de partida a pergunta “Como se comportaram alguns temas e mitos ao longo da história da literatura de Cabo Verde? Que caminho percorreram?” Para tentar dar-lhe resposta recorremos à metodologia comparativista, com o objetivo de analisar as evoluções e possíveis mudanças ocorridas ao longo dos tempos, a partir do cruzamento transversal entre temas e mitos em épocas diferentes. Foi assim necessário abordar a literatura cabo-verdiana, na sua relação profunda com a história do país, considerando os seus três grandes momentos: um tempo “ indefinido” que vai até 1936, um segundo que vai de 1936 até 1975 e, por último, o que vai desde essa data até à atualidade. Ao longo dessa análise, e a partir de um corpus textual necessariamente circunscrito, fomos detetando as variantes, as diferentes atualizações ocorridas nesta literatura, geralmente provocadas por fatores de ordem geográfica, pela evolução histórico-social, por fatores ideológicos que se prenderam sobretudo com a falta de liberdade vivida até 1975. Esta abordagem comparativista, a análise intertextual que lhe é inerente, proporcionou, não uma simples comparação, mas o desvendar de relações múltiplas existentes entre as obras, o corpus literário escolhido, e os tempos que lhes deram origem, permitindo assim conhecer as partes e, consequentemente o todo através do “desocultamento do oculto”. Constatou-se uma migração dos temas e dos mitos entre as literaturas dos três momentos. Em certos casos, alguns elementos permaneceram, mas com novas representações, noutros assumem significados radicalmente diferentes dados os atuais contextos da sua recepção. Relativamente aos mitos, observou-se a sua crescente dessacralização, em sintonia com o progresso que o país foi conhecendo após a independência nacional. A leitura que fomos fazendo conduziu-nos deste modo a uma viagem ao passado do país. Esta leitura transversal, alicerçada na história, dando conta das transformações ocorridas ao longo dos tempos, mostrou-nos ainda de forma cabal a necessidade de se introduzirem mudanças no ensino da literatura nas escolas cabo-verdianas. Uma mudança que deverá passar por uma abordagem comparativista, que privilegia as relações entre textos de diferentes épocas, a sua perspetivação interdisciplinar com outras formas de expressão, capaz de transformar o aluno-mero-receptor num leitor ativo, implicado numa realidade que lhe diz respeito.

In the Arabidopsis root meristem, polar auxin transport creates a transcriptional auxin response gradient that peaks at the stem cell niche and gradually decreases as stem cell daughters divide and differentiate [1-3]. The amplitude and extent of this gradient are essential for both stem cell maintenance and root meristem growth [4, 5]. To investigate why expression of some auxin-responsive genes, such as the essential root meristem growth regulator BREVIS RADIX (BRX) [6], deviates from this gradient, we combined experimental and computational approaches. We created cellular-level root meristem models that accurately reproduce distribution of nuclear auxin activity and allow dynamic modeling of regulatory processes to guide experimentation. Expression profiles deviating from the auxin gradient could only be modeled after intersection of auxin activity with the observed differential endocytosis pattern and positive autoregulatory feedback through plasma-membrane-to-nucleus transfer of BRX. Because BRX is required for expression of certain auxin response factor targets, our data suggest a cell-type-specific endocytosis-dependent input into transcriptional auxin perception. This input sustains expression of a subset of auxin-responsive genes across the root meristem's division and transition zones and is essential for meristem growth. Thus, the endocytosis pattern provides specific positional information to modulate auxin response.

The objective of this experiment was to quantify the extramatrical mycelium of the arbuscular mycorrhizal (AM) fungus Glomus etunicatum (Becker & Gerdemann) grown on maize (Zea mays L. var. Piranão) provided with various levels of phosphate fertilizer and harvested at 30, 60 and 90 days after planting (DAP). Total extramatrical mycelium (TEM) was extracted from soil using a modified membrane filtration method, followed by quantification using a grid intersection technique. Active extramatrical mycelium (AEM) proportion was determined using an enzymatic method which measured dehydrogenase activity by following iodonitrotetrazolium reduction. At low levels of added P, there was relatively less TEM than at high levels of added P, but the AEM proportion at low soil P availability was significantly greater than at high soil P.

SUMMARY: We present a tool designed for visualization of large-scale genetic and genomic data exemplified by results from genome-wide association studies. This software provides an integrated framework to facilitate the interpretation of SNP association studies in genomic context. Gene annotations can be retrieved from Ensembl, linkage disequilibrium data downloaded from HapMap and custom data imported in BED or WIG format. AssociationViewer integrates functionalities that enable the aggregation or intersection of data tracks. It implements an efficient cache system and allows the display of several, very large-scale genomic datasets. AVAILABILITY: The Java code for AssociationViewer is distributed under the GNU General Public Licence and has been tested on Microsoft Windows XP, MacOSX and GNU/Linux operating systems. It is available from the SourceForge repository. This also includes Java webstart, documentation and example datafiles.

Let I be an ideal in a local Cohen-Macaulay ring (A, m). Assume I to be generically a complete intersection of positive height. We compute the depth of the Rees algebra and the form ring of I when the analytic deviation of I equals one and its reduction number is also at most one. The formu- las we obtain coincide with the already known formulas for almost complete intersection ideals.

The purpose of this paper is two fold. First, we give an upper bound on the orderof a multisecant line to an integral arithmetically Cohen-Macaulay subscheme in Pn of codimension two in terms of the Hilbert function. Secondly, we givean explicit description of the singular locus of the blow up of an arbitrary local ring at a complete intersection ideal. This description is used to refine standardlinking theorem. These results are tied together by the construction of sharp examples for the bound, which uses the linking theorems.

It is shown that Hirzebruch's result on the Chern classes of a complete intersection of nonsingular hypersurfaces in general position in PN(C), is also valid for any nonsingular complete intersection. Then rela- tions between Euler characteristic, class and Milnor number are pointed out.

Many studies have forecasted the possible impact of climate change on plant distribution using models based on ecological niche theory. In their basic implementation, niche-based models do not constrain predictions by dispersal limitations. Hence, most niche-based modelling studies published so far have assumed dispersal to be either unlimited or null. However, depending on the rate of climatic change, the landscape fragmentation and the dispersal capabilities of individual species, these assumptions are likely to prove inaccurate, leading to under- or overestimation of future species distributions and yielding large uncertainty between these two extremes. As a result, the concepts of "potentially suitable" and "potentially colonisable" habitat are expected to differ significantly. To quantify to what extent these two concepts can differ, we developed MIGCLIM, a model simulating plant dispersal under climate change and landscape fragmentation scenarios. MIGCLIM implements various parameters, such as dispersal distance, increase in reproductive potential over time, barriers to dispersal or long distance dispersal. Several simulations were run for two virtual species in a study area of the western Swiss Alps, by varying dispersal distance and other parameters. Each simulation covered the hundred-year period 2001-2100 and three different IPCC-based temperature warming scenarios were considered. Our results indicate that: (i) using realistic parameter values, the future potential distributions generated using MIGCLIM can differ significantly (up to more than 95% decrease in colonized surface) from those that ignore dispersal; (ii) this divergence increases both with increasing climate warming and over longer time periods; (iii) the uncertainty associated with the warming scenario can be nearly as large as the one related to dispersal parameters; (iv) accounting for dispersal, even roughly, can importantly reduce uncertainty in projections.

In 1891 Théodore Flournoy (1854-1920) became the first Professor of Psychology to be appointed at the University of Geneva, and his teaching regularly included references to religion. His successor, Georges Berguer, who taught psychology of religion, began as privat-docent in 1910 and received a full professorship in Religious Psychology and the History of Religion in 1928. French-speaking Switzerland is one of the rare places in the world where psychology of religion has been taught continuously since the very beginning of the 20th century. The aim of this article is to shed light on this tradition and especially on Georges Berguer (retired in 1944) and Edmond Rochedieu (retired in 1965) who succeeded Flournoy. This historical enterprise concludes with some reflections on the role of the psychology of religion at the intersection of psychology and the study of religions.
Roadway Lighting and Safety: Phase II – Monitoring Quality, Durability and Efficiency, November 2011

This Phase II project follows a previous project titled Strategies to Address Nighttime Crashes at Rural, Unsignalized Intersections. Based on the results of the previous study, the Iowa Highway Research Board (IHRB) indicated interest in pursuing further research to address the quality of lighting, rather than just the presence of light, with respect to safety. The research team supplemented the literature review from the previous study, specifically addressing lighting level in terms of measurement, the relationship between light levels and safety, and lamp durability and efficiency. The Center for Transportation Research and Education (CTRE) teamed with a national research leader in roadway lighting, Virginia Tech Transportation Institute (VTTI) to collect the data. An integral instrument to the data collection efforts was the creation of the Roadway Monitoring System (RMS). The RMS allowed the research team to collect lighting data and approach information for each rural intersection identified in the previous phase. After data cleanup, the final data set contained illuminance data for 101 lighted intersections (of 137 lighted intersections in the first study). Data analysis included a robust statistical analysis based on Bayesian techniques. Average illuminance, average glare, and average uniformity ratio values were used to classify quality of lighting at the intersections.

Red light running (RLR) is a problem in the US that has resulted in 165,000 injuries and 907 fatalities annually. In Iowa, RLR-related crashes make up 24.5 percent of all crashes and account for 31.7 percent of fatal and major injury crashes at signalized intersections. RLR crashes are a safety concern due to the increased likelihood of injury compared to other types of crashes. One tool used to combat red light running is automated enforcement in the form of RLR cameras. Automated enforcement, while effective, is often controversial. Cedar Rapids, Iowa installed RLR and speeding cameras at seven intersections across the city. The intersections were chosen based on crash rates and whether cameras could feasibly be placed at the intersection approaches. The cameras were placed starting in February 2010 with the last one becoming operational in December 2010. An analysis of the effect of the cameras on safety at these intersections was determined prudent in helping to justify the installation and effectiveness of the cameras. The objective of this research was to assess the safety effectiveness of the RLR program that has been implemented in Cedar Rapids. This was accomplished by analyzing data to determine changes in the following metrics: Reductions in red light violation rates based on overall changes, time of day changes, and changes by lane Effectiveness of the cameras over time Time in which those running the red light enter the intersection Changes in the average headway between vehicles entering the intersection
