Les organisations africaines seraient peu performantes. Leurs dirigeants seraient mal formés, ils seraient marqués par une mentalité traditionnelle peu conciliable avec la modernité managériale et la recherche de la rentabilité, etc. Les auteurs de l’ouvrage ont voulu déconstruire ce cliché. Dans une quinzaine de contributions qui se réfèrent à des approches disciplinaires variées (anthropologie, économie, sociologie, gestion), ils analysent de près les spécificités des entreprises d’Afrique sub-saharienne (leur ancrage familial et communautaire, l’incidence qu’ont sur elles les croyances magico-religieuses, etc.) et ils explorent l’apport d’outils de gestion tantôt inspirés des traditions locales (tontine d’entreprise, conseil des sages, etc.), tantôt importés de l’Occident (qualité totale, externalisation, etc.). Il en ressort une image contrastée des facteurs contribuant à la performance des organisations africaines ainsi que des pistes susceptibles de l’améliorer de façon durable. [less ▲]

In previous studies, we described subclinical abnormalities of neuromuscular transmission and cerebellar functions in migraineurs. The aim of this study was to search if these two functions are correlated in the same patient. Thirteen migraineurs [five without aura (MO) and eight with aura (MA)] underwent both stimulation-SFEMG and 3D-movement analysis. Single fiber EMG (SFEMG) results were expressed as the "mean value of consecutive differences" (mean MCD). Precision of arm-reaching movements (measured with an infrared optoelectronic tracking system) was expressed as the average deviation in the horizontal plane. Median values of mean MCD and mean horizontal deviation were not different between MO and MA. However, in MA, but not in MO, both variables were positively correlated. Thus, we conclude that neuromuscular transmission and cerebellar functions are correlated in the same patient when affected by migraine with aura. We suggest that this correlation might be due to a common molecular abnormality. [less ▲]

Face la population transnationale d’origine latino-américaine croissante à travers le monde – spécialement présente en Espagne et aux États-Unis – je me suis intéressée à la création littéraire en tant que mise en récit de Soi et de l’Autre. Dans le cadre de cette littérature latinoaméricaine de la migration, je me centrerai sur la représentation du genre dans ces romans, c'est-à-dire sur ces attitudes performatives qui (re)produisent les normes et les modèles mais aussi parfois des corps a-normatifs et illisibles (Butler, T. de Lauretis). Je proposerai donc d’articuler la notion stimulante de performance de genre telle que proposée par J. Butler à celle d’ethos rhétorique (Amossy, Maingueneau) dans le but d’analyser la voix narrative du roman The Brief Wondrous Life of Oscar Wao de Junot Díaz (2008). Cette lecture nous permettra de mettre en lumière le jeu de va-et-vient par rapport aux stéréotypes de genre qui font autorité et, plus fondamentalement, la construction d’un corps queer apatride qui s’oppose "naturellement" au corps masculin de la diaspora.

A novel, multidimensional on-line SPE-LC method with electrochemical detection is described for the fully automated and direct analysis of the catecholamines norepinephrine, epinephrine and dopamine in urine. The integrated extractive clean-up of the raw biofluid is based on a SPE-column packed with restricted access material (RAM) which is modified with the affinity ligand nitrophenylboronic acid. The method was fully validated according to a recent approach based on an accuracy profile. The acceptance limits were set at +/- 15% of the nominal concentration values. The method was found accurate over a concentration range from 15 to 500 mu g/l for norepinephrine, from 5 to 500 mu g/l for epinephrine and from 50 to 500 mu g/l for dopamine. The relative risk for the use of the validated method in routine analysis was also assessed based on this validation strategy. It was found that at most 3.5% of future sample measurements will fall outside the acceptance limits. This demonstrates the high reliability of the analytical method described. Moreover, the measurements uncertainties were deduced from the validation experiments without any additional effort. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

As building insulation level increases, the coupling of ventilation systems with building enveloppe airtightness becomes an important issue in order to improve buildings energy performances. A building ventilation model can be built on a set of resistances and generators in order to handle infiltration, natural ventilation as well as fan driven air flows. The model is able to assess the indoor air humidity level and the building energy balance. Double flow ventilation can be handled through decentralized air handling terminals (DAHT), integrated in window ledges. A model of DAHT can be combined with the model of a whole building envelope, including infiltrations as well as dynamic behaviour, allowing comparisons with classical ventilation systems, such as natural or hybrid systems, or with centralized double flow systems. Results regarding energy consumptions, air humidity levels and superficial condensation risks can be analysed. Fresh air flow can be calibrated in order to meet air quality standards related to indoor humidity level and CO2 concentration. The modelization of buiding indoor hygro-thermal climate allows a complete assessment of the seasonal heat exchanger efficiency, including heat recovery through the condensation of indoor air humidity when it flows through the exchanger.

This paper proposes a survey of the performances of binary classifiers based on low-level audio features, for music similarity in large-scale databases. Various low-level descriptors are used individually and then combined using several fusion schemes in a content-based audio retrieval system. We show the performances of the classifiers in terms of pruning and loss and we demonstrate that some combination schemes achieve a better performance at a minimum computational cost. [less ▲]

The special properties of volume phase holographic gratings make them promising candidates for spectrometry applications where high spectral resolution, low levels of straylight, and low polarization sensitivity are required. Therefore it is of interest to assess the maturity and suitability of volume phase holographic gratings as enabling technologies for future space missions, with demanding requirements for spectrometry. One of the main areas of research is related to grating ageing under space radiation. In the present paper, two volume grating technologies are analyzed and compared under gamma irradiation. The performances of both technologies, the photo–thermo–refractive glass and the Dichromated Gelatin, are tested on samples and assessed in the and near-infrared bands. The diffraction efficiency degradation under gamma irradiation is assessed. [less ▲]

Nowadays, Belgian poultry breeding is characterized by a strong biodiversity that is nevertheless greatly endangered. The present work aims at evaluating the zootechnical potential of an ancient poultry breed originating from the Franco-Belgian Ardennes region, the Ardennaise. This breed shows an important phenotypic variation, with 10 different varieties being recognized. This study evaluates the Ardennaise production performances and is divided into three parts: (1) the analysis of the growth and the consumption indices over a twelve weeks period, (2) the comparison of the growth over seventeen weeks in four varieties, (3) the study of eggs number and eggs weight over 70 weeks laying. The results indicate that the Ardennaise breed constitutes a good dual purpose breed that could be interestingly submitted to selection. Its use in industrial crosses for egg composition amelioration is also proposed. Lastly, this works shows the importance of extending the here developed evaluation protocol to other Belgian endangered poultry breeds to motivate the necessary conservation programs. [less ▲]
