This article proposes to analyse the discourses on “integration” developed during the last few years within various “ethnics” churches (France-Belgium). Of Pentecostal and Evangelical obedience, these churches, stemming from Congolese’s migrations (DRC), can be estimated to several hundreds and even up to a few thousands in Europe. Some constant can be observed in this new branch of Protestantism despite its fragmented and plural movement, particularly the right to think oneself beyond the logics of reduction to otherness. The integrationist discourse produced constitutes a real break with the ideas carried by the autochthon order of both hierarchies and centralities. [less ▲]

Le modèle de Karasek (1979) est l’un des modèles le plus utilisé dans les recherches sur le lien travail-famille et sur le stress professionnel. Parmi les variables qu’il inclut, figurent le support social du supérieur et des collègues. À notre connaissance, peu d’études ont essayé d’analyser le lien entre l’interférence travail-famille, le stress négatif et d’autres sources de support social tel que le support perçu de l’organisation. Or, en accord avec la méta-analyse de Rhoades & Eisenberger en 2002, nous faisons l’hypothèse que le support organisationnel perçu joue un rôle central dans le lien entre les caractéristiques du travail, l’interférence négative travail-famille et le stress négatif qui en découle. Notre étude s’est réalisée dans un hôpital belge auprès de 266 membres du personnel soignant. Le questionnaire utilisé comprend : le Job Content Questionnaire de Karasek; l’échelle de support organisationnel perçu de Eisenberger (1986), l’échelle d’interférence négative du travail sur la famille (SWING, Geurts, 2004) et le stress négatif (SPPN, Hansez et al., 2004). Il en résulte que le support organisationnel perçu joue un rôle central dans les relations entre certaines caractéristiques du travail, l’interférence négative travail-famille et le stress par le biais d’une double médiation. En outre, l’effet négatif des exigences de travail sur le support organisationnel perçu est modéré par la latitude de décision que les employés peuvent avoir dans leur travail. Les résultats suggèrent qu’introduire le support organisationnel perçu dans des modèles liés aux relations travail-famille enrichirait les deux courants de recherche envisagés dans cette étude. En outre, le type de modèle utilisé dans cette recherche pourrait aussi être appliqué à d’autres types de variables dépendantes (e.g. la performance au travail). [less ▲]

The homogeneous charge compression ignition is an alternative combustion technology that can reduce automobile pollution, provided that the exhaust emission can be controlled. A parametric study can be useful in order to gain more understanding in the emission reduction possibilities via this new combustion technology. For this purpose, the inlet temperature, the equivalence ratio and the compression ratio are changed, respectively, from 30 to 70 degrees C, 0.28 to 0.41 and 6 to 14. Also the diluting, thermal and chemical effects of exhaust gas recirculation were studied. The emission of CO, CO2, O-2 and hydrocarbons has been measured using primary reference fuels. It appears that an increase in the inlet temperature, the EGR temperature, the equivalence ratio and the compression ratio results into a decrease of the emissions of CO and the hydrocarbons of up to 75%. The emission of CO2 increased, however, by 50%. The chemical parameters showed more complicated effects, resulting into a decrease or increase of the emissions, depending on whether the overall reactivity increased or not. If the reactivity increased, generally, the emissions of CO and hydrocarbons increased, while that of CO2 increased. The increase of CO2 emissions could be compensated by altering the compression ratio and the EGR parameters, making it possible to control the emission of the HCCI engine. (c) 2008 Elsevier Ltd.

The aim of this experiment was to study the kinetics of anti-eCG (equine chorionic gonadotrophin) antibodies in relation to eCG dose (8 or 25 IU) and number of injections (n = 11) in comparison with a control group (no injection), and to relate antibody production to sexual receptivity and productivity of rabbit does. In all, 124 lactating primiparous rabbit does were inseminated every 35 days for a year. Just before eCG injection (48 h before insemination), blood samples were collected from all the does to assay anti-eCG antibodies. The anti-eCG antibody binding rate, regardless of the injected dose, shows that none of the does developed detectable anti-eCG antibodies before the 7th injection. The level of detectable anti-eCG antibodies began to show an increase at the 7th injection and was significant only for the 25 IU dose at the 11th injection. At the end of the experiment, 15% and 39% of does treated with 8 and 25 IU, respectively, developed immunity to eCG (binding rate >6%: higher binding rate of the control group). Consequently, the immune response depends on the eCG dose and on the number of injections. Moreover, productivity of does estimated from the number of weaned rabbits produced per insemination is not influenced by the level of eCG antibodies (7.0 and 6.9 for binding rate <6% and binding rate 6%, respectively). Only 19 inseminations (n = 6 and n = 13 for 8 and 25 IU, respectively) were made on hyperimmune does. Consequently, the immune response to eCG seems to be marginal for rabbit does. Moreover, under the described experimental conditions, reproductive performances of hyperimmune does were not affected [less ▲]

Economic reasoning is a distinctive feature of competition law. At first sight, it may appear as foreign to judges. A closer analysis, however, shows that there is no conflict of logic between economic and judicial reasoning. Some points of convergence between these modes of reasoning are underlined. In addition, it is submitted that obstacles to judicial acknowledgement of economic reasoning are purely relative. The proposed analysis then proceeds to investigate how economic reasoning may be incorporated into judicial methods. It is shown that this is achieved by way of ordinary mechanisms. Indeed judges may use economic analysis to determine the relevant facts and legal tests. It follows that judicial control over economic reasoning – including that of competition authorities – can be explained by a very general theory of judicial review, according to which the depth of judicial control over grounds of fact and law depends on the dynamics of litigants’ contentions.

In order to understand better the auto-ignition process in an HCCI engine, the influence of some important parameters on the auto-ignition is investigated. The inlet temperature, the equivalence ratio and the compression ratio were varied and their influence on the pressure, the heat release and the ignition delays were measured, The inlet temperature was changed from 25 to 70 degrees C and the equivalence ratio from 0.18 to 0.41, while the compression ratio varied from 6 to 13.5. The fuels that were investigated were PRF40 and n-heptane. These three parameters appeared to decrease the ignition delays, with the inlet temperature having the least influence and the compression ratio the most. A previously experimentally validated reduced surrogate mechanism, for mixtures of n-heptane, iso-octane and toluene, has been used to explain observations of the auto-ignition process. The same kinetic mechanism is used to better understand the underlying chemical and physical phenomena that make the influence of a certain parameter change according to the operating conditions. This can be useful for the control of the auto-ignition process in an HCCI engine. (C) 2008 Elsevier B.V. All rights reserved. [less ▲]

Structures and ontogeny of schools in two cichlid fishes: quantitative approach with computerized videotracking systems in Oreochromis niloticus and Pelvicachromis pulcher. by Johann DELCOURT (Behavioural Biology Unit, Ethology and Animal Psychology, University of Liège, Belgium) The research works presented in this thesis, using new ethometric techniques based on digital imaging analysis, concerns several questions relating to the study of shoaling and schooling behaviours in early stages of life in two Cichlid species. Our two model species, the Nile tilapia (Oreochromis niloticus L.) and Pelvicachromis pulcher, are respectively a mouthbreeder and a substrate breeder. These reproductive and parental strategies have a direct impact on the ontogeny of fry. In this study, we have worked at understanding the impact of these strategies on the ontogeny of shoaling and schooling behaviours. The characterization of these behaviours needed the elaboration of new videotracking systems able to track individually a large number of fish, and the analysis of the spatial and dynamical structure of the group. After an extensive general introduction devoted to the shoaling and schooling behaviours in regards of the ethological study plan, we present our works in three major goals. These three topics concern: 1. Lab works using some classical methods of direct observation and a technique of computerised vision systems (Ethovision®). Moreover, Laboratory studies of fish groups were conducted to develop a new multitracking system, in collaboration with the G.R.A.S.P. (ULg), able to track a large number of unmarked individuals (up to 100 fishes) during several minutes. Thanks these two tracking systems, we studied the fry behaviours at the individual and the groups levels. 2. The emergence conditions of these behaviours. Are the fry able to adopt these behaviours in absence of parents, in absence of external stimuli? In this context, we described the spatial and dynamical (local and global) structures of groups to understand the mechanisms allowing the existence of schools. 3. The ontogeny of shoaling and schooling behaviours in the two model parental species. The first part exposes research devoted to the application, development and validation of the use of two videotracking systems (presented in the material and methods section). The advantages, capacities and limits of these systems are presented. The work concerning the emergence (the mechanisms) and the ontogeny are presented in scientific paper format in the “Results” section. A large general discussion centred on the three major goals (development of new ethometric tools, the structures and mechanisms of schools and the ontogeny of shoaling and schooling behaviours) concludes this PhD dissertation.

BACKGROUND: Intraindividual genetic variability plays a central role in deltaretrovirus replication and associated leukemogenesis in animals as in humans. To date, the replication of these viruses has only been investigated during the chronic phase of the infection when they mainly spread through the clonal expansion of their host cells, vary through a somatic mutation process without evidence for reverse transcriptase (RT)-associated substitution. Primary infection of a new organism necessary involves allogenic cell infection and thus reverse transcription. RESULTS: Here we demonstrate that the primary experimental bovine leukemia virus (BLV) infection of sheep displays an early and intense burst of horizontal replicative dissemination of the virus generating frequent RT-associated substitutions that account for 69% of the in vivo BLV genetic variability during the first 8 months of the infection. During this period, evidence has been found of a cell-to-cell passage of a mutated sequence and of a sequence having undergone both RT-associated and somatic mutations. The detection of RT-dependent proviral substitution was restricted to a narrow window encompassing the first 250 days following seroconversion. CONCLUSION: In contrast to lentiviruses, deltaretroviruses display two time-dependent mechanisms of genetic variation that parallel their two-step nature of replication in vivo. We propose that the early and transient RT-based horizontal replication helps the virus escape the first wave of host immune response whereas somatic-dependent genetic variability during persistent clonal expansion helps infected clones escape the persistent and intense immune pressure that characterizes the chronic phase of deltaretrovirus infection.
