L’étude de la responsabilité sociale des entreprises (RSE) cherche à analyser les démarches volontaires dans lesquelles des entreprises à but de lucre s'engagent afin de respecter, au-delà de leur objectif de rentabilité économique, des exigences sociales et environnementales, et d’améliorer les relations avec toutes les parties concernées par leurs activités (Bender et Pigeyre, 2003). Ces initiatives rappellent des pratiques à l'œuvre depuis plus d'un siècle dans les organisations d'économie sociale (OES), qui essayent d'atteindre des objectifs sociétaux par le biais d'une activité économique (Defourny et Develtere, 1999). Si, à la suite de Levi (1998), on place les entreprises privées "classiques" et les OES aux extrémités d'un continuum qui s'étendrait de la "performance économique" à la "performance sociétale", on peut émettre l'hypothèse selon laquelle l'apparition de la RSE provoque un double mouvement. D'une part, les entreprises privées recherchent une certaine performance sociétale et, d'autre part, les OES visent davantage de performance économique en adoptant parfois un comportement plus typiquement commercial (Weisbrod, 1998). En conséquence, alors que les rôles respectifs des différentes catégories d’acteurs semblaient clairement définis, les frontières se font à présent plus floues et certains domaines d’activité sont indubitablement témoins d’un rapprochement entre le secteur privé "classique" et le secteur de l'économie sociale. Néanmoins, ces deux ensembles ne semblent pas mus l’un vers l’autre de manière endogène et autonome : au contraire, il y a lieu de penser que les évolutions respectives sont le fruit d’influences réciproques. Notre article a pour but de faire le point sur cette hypothèse de rapprochement, en partant des rôles traditionnels des institutions au sein du système socio-économique et en observant de quelle manière le monde des entreprises et celui de l’économie sociale se sont non seulement rapprochés, mais également influencés réciproquement. Notre réflexion est structurée en trois étapes. Tout d'abord, nous présentons brièvement le contenu que nous associons aux deux concepts principaux sur lesquels repose notre argumentation (l'économie sociale et la RSE) et nous nous basons sur les arguments de la théorie économique institutionnelle pour identifier les atouts respectifs et les rôles traditionnellement dévolus aux grandes catégories d'acteurs dans nos économies. Dans un deuxième temps, nous montrons pourquoi on peut considérer la rencontre entre les OES et les entreprises à but de profit comme un des stimuli du mouvement de RSE et combien ces interactions peuvent potentiellement transformer les comportements de ces deux types d'acteurs. Enfin, nous illustrons notre hypothèse par une analyse des interactions entre OES et entreprises en quête de responsabilité sociale dans la filière du commerce équitable et éthique. Pour ce faire, nous nous basons principalement sur une étude empirique exploratoire menée sur la scène équitable belge et portant sur ces interactions et leurs conséquences en termes de gestion de l’activité économique (Huybrechts et Mertens, 2006).

The estrogen deficit occurring at menopause manifests itself under various modalities in the diverse organs and their functions. Skin does not escape this global involutive process. In addition to the effects of chronological ageing, sunlight exposure and other environmental and endogenous stimuli, the climacteric appears to exert some dramatic consequences on skin biology and aspect. The epidermis, its adnexae and the dermis are altered by this process. The epidermis may become xerotic and exhibits altered functions. The dermis thins out and its elasticity decreases in concert with the decline in bone mass. The skin microcirculation is impaired. These aspects are some of the better-worked out skin climacteric changes of which in turn seem to be stabilized or in part reversible with hormone replacement therapy (HRT). [less ▲]

Arachidonic acid (AA) metabolites are key mediators involved in the pathogenesis of numerous cardiovascular, pulmonary, inflammatory, and thromboembolic diseases. One of these bioactive metabolites of particular importance is thromboxane A(2) (TXA(2)). It is produced by the action of thromboxane synthase on the prostaglandin endoperoxide H-2 (PGH(2)) which results from the enzymatic transformation of AA by the cyclooxygenases. It is a potent inducer of platelet aggregation, vasoconstriction and bronchoconstriction, and has been involved in a series of major pathophysiological conditions. Therefore, TXA(2) receptor antagonists, thromboxane synthase inhibitors and drugs combining both properties have been developed by different laboratories since the early 1980s. Several Compounds have been launched on the market and others are tinder clinical evaluation. In the first part of this review. we will describe the physiological properties of TXA(2), thromboxane synthase and thromboxane receptors. The second part is dedicated to a description of each class of thromboxane modulators with the advantages and disadvantages they offer. In the third part. we aim to describe recent studies performed with the most interesting thromboxane modulators in major pathologies: myocardial infarction and thrombosis, atherosclerosis, diabetes, pulmonary embolism, septic shock.. preeclampsia, and asthma. Each pathology will be systematically reviewed. Finally, in the last part we will highlight the latest perspectives in drug design of thromboxane modulators and in their future therapeutic applications such as cancer, metastasis and angiogenesis.

The urban mosquito Culex quinquefasciatus Say (Diptera: Culicidae) uses chemicals to locate suitable water pools for oviposition. These chemicals when identified can be used to trap gravid female mosquitoes. Experiments in Davis and in Sacramento (California, in the United States) were made to improve the trapping efficiency of Reiter/Cumming gravid traps baited by several attractants (or attractant blends). Unfortunately, it appeared that the number of gravid female mosquitoes collected was not sufficient to differentiate the efficacy of attractant blends tested by statistical analysis. However, a positive correlation between the total mosquito number collected daily and the highest humidity shows that the mosquito oviposition activity seems to be influenced by the humidity during the night. Observations on total number of mosquitoes and the highest temperature seem to reveal a threshold temperature which is critical for the adult mosquito survival. A coupled gas chromatography – electronantennography (GC-EAD) protocol was also developed step by step in order to find new Culex quinquefasciatus oviposition attractants. After obtaining repetitive electroantennographic (EA) response, two comparison experiments (SPME fiber type and infusion type) were made to finalize the specific GC-EAD/SPME protocol. This with the aim to prospect new attractants from fermented Bermuda grass infusion. Analyses based on all results permit to distinguish the EA responses from random perturbations (electromagnetic and vibration). GC-EAD/SPME of Bermuda grass infusion analyses confirms the presence of 10 and the activity of 9 chemical compounds as established by Du and Millar in 1999. Furthermore, experiments on Culex quinquefasciatus performed with the new protocol, brought to light the EA activity of 10 other unknown chemicals, 7 of which are low molecular weight chemical compounds. These new chemicals have now to be identified and their ability to elicit EA responses still has to be confirmed. [less ▲]

This paper compares three methods to determine the earing profile that appears during the deep-drawing test of a circular steel sheet. Three steel grades will be studied. The first method is an experimental test made by a hydraulic press. The second one is a finite ele-ment method (FEM) deep-drawing simulation using a micro-macro texture based constitutive law. The last one directly determines the general aspect of the earing profile from the yield locus which is computed from the initial texture. The goal of this study is to validate the last approach. So, an earing profile prediction can quickly be obtained just from material’s tex-ture. [less ▲]

The purpose of this study was to investigate the reproducibility of findings derived from a new iso-inertial dynamometer during bench press (BP) and squat (SQ) and to provide descriptive data for recreational athletes. A position transducer and accelerometer were combined to assess velocity and power during free weight lifting exercises. Simulated movement with a pulley system revealed the excellent technical consistency of the dynamometer. Sixteen male subjects participated in the study. Iso-inertial tests consisted of lifting as fast as possible four different relative loads (35, 50, 70, 90% 1RM in BP and 45, 60, 75, 90% 1RM in SQ). The test was repeated one week later. Analysis of variance revealed no significant variation between sessions or trials. Reproducibility was better in velocity than in power, although it remained fairly good in both exercises (coefficients of variation [CV] never exceeding 10%) except for the time to peak power parameter. Descriptive data confirmed the classical force-velocity and force-power relationships for BP and SQ. In conclusion, this study demonstrated reliable measurements in BP and SQ iso-inertial exercises. Monitoring force-velocity and force-power relationships offers an original functional approach in strength training supervision. [less ▲]

It is clear that even low rate smoking is hazardous for health, the risk being independently increased by the daily number of cigarettes smoked and by the duration of smoking. The question raised is thus: will an adolescent experimenter be a non smoker, an experimenter for ever, a regular smoker, light or heavy? This short review shows that there are numerous factors from genetics, to familial environment not limited to tobacco issues, smoking situation at school as well as school performances of the student, and also individual psychological characteristics. The experimenter is a very good target for smoking cessation actions and should deserve particular attention from preventive medicine and, thus, from school medicine, before he becomes a regular smoker, who will be more resistant to smoking cessation programs.

The prescription of a pharmacological agent concludes most medical visits. The rational basis of drug prescription by the physician relies on numerous pharmacodynamic, pharmacokinetic, pragmatic and economic considerations. However, it is a pity to notice that one patient out of two does not strictly follow the pharmacological treatment as it was prescribed. This article analyses some problems of the patient-doctor relationship, which may reduce medication compliance, and provides practical advice for improving such a situation in order to enhance both efficacy and safety of drug prescribing.
