Stress at work has become a major problematic in Europe this last decade. The European and national legal framework has been developed, and several methods for stress diagnosis and stress management intervention can be listed. In this context, a systematic examination of diagnosis and interventions taking place in companies is necessary. The objectives of the study were 1) the evaluation of work stress diagnosis practices among Belgian companies, and 2) the identification of factors stimulating or blocking the implementation of stress management interventions. A survey was used to collect data about work stress diagnosis practices. The first objective was explored trough qualitative open questions about stress diagnosis and intervention. The second objective was achieved using a specific questionnaire elaborated for the purpose of the study. On the basis of a review of the scientific literature, this questionnaire assessed stimulating and blocking factors for implementing stress management interventions. The sample includes 180 Belgian companies from different sectors of activity and with different size (from 20 to more than 10000 workers). Only one out of six companies had implemented a diagnosis of stress. Among companies with a stress diagnosis, only one out of two had implemented actions, and only one out of four entered in an evaluation stage. Stimulating factors related to the methodology implemented and the communication process were identified, as well as blocking factors concerned with financial/temporal constraints and the context of change in the company, a factor which is rather new regarding the existing literature. The discussion includes four points of analysis. The interventions which are implemented are clearly concerned with the primary approach focusing on the work environment. Second, the results give support to the necessity for a systematic evaluation process of stress management interventions. Moreover the results give evidence for a need of sensitization and publication of best practices about the necessary stages in the stress prevention process as well as about stimulating and blocking factors. This holds especially true for small size companies which realize less diagnosis than bigger ones. It is also important for companies which are not yet involved in a stress diagnosis, that are less aware of the impact of financial and temporal constraints. [less ▲]

L’évaluation des pratiques éducatives est un champ nouveau des recherches tant en didactique générale qu’en didactique des disciplines. Les travaux relatifs à la géographie étant à notre connaissance encore rares, le propos de cette communication est de dresser un premier bilan en nous appuyant principalement sur des recherches menées par des chercheurs en sciences de l’éducation et sur notre expérience personnelle. Après avoir tenté de définir l'objet de ces pratiques et leur intérêt comme objet d'étude, l'article discute des pratiques en géographie et propose quelques pistes de recherche-action. [less ▲]

La vie des personnes souffrant d’une maladie mentale est souvent caractérisée par une pauvreté de la vie personnelle, professionnelle et sociale. Les programmes de réhabilitation psychiatrique ont été développés pour soutenir l’insertion sociale et professionnelle de ces personnes. Les recherches antérieures ont montré que ces programmes peuvent contribuer à l’amélioration du bien-être de l'individu. L’objectif de la présente étude a été d’évaluer les effets d’interventions cognitives et comportementales offertes par des Centres de Réadaptation Fonctionnelle (CRF) en Belgique, sur la symptomatologie clinique, le fonctionnement cognitif et social. Une étude longitudinale a été conduite dans laquelle les patients ont été évalués après 6 et 12 mois de thérapie. Les résultats soutiennent l’idée que les Centres de Réadaptation Fonctionnelle offrent des interventions thérapeutiques qui peuvent améliorer le fonctionnement social et cognitif des patients ainsi que leur symptomatologie clinique.

Specific stream powers were calculated at more than 70 discharge stations along rivers with catchments between 10 and 2500 km². In order to calculate the stream power, bankfull discharge, average slope and width were calculated at each station. The relationship between, on one hand, the size of the catchments and the bankfull discharge and, on the other, the size of the catchments and the width of the channels were highlighted. These allow several regional differentiations to be highlighted. With regard to the specific stream power, there is a clear contrast between the rivers from the South and the North Ardenn which show an East-West gradient of decreasing stream power. Rivers from Condroz and Entre-Vesdre-et-Meuse have intermediary values. Rivers from Hesbaye have very low stream powers. Stream power values partly account for the evolution of the river bed dynamics : in Hesbaye, where the rivers have low stream power (less than 15 W/m²), the river’s course is rather stable for a few centuries. In the South Ardenn (stream power lower than 30 W/m²), meanders are quite active and the meandering cycle is longer than a century. In the Entre-Verdre-et-Meuse (stream power between 30 and 40 W/m²), meanders are active and the river is able to readjust following anthropogenic constructions (deflectors). However, our observations deviate from threshold values proposed in the literature. Thus, the Geer (Hesbaye) is able to readjust and to create a secondary meandering following log-jams edifications, despite a stream power lower than 15 W/m². In the rivers such as the Ourthe in Famenne, despite rather high stream power values (higher than 50 to 70 W/m²), the meandering cycle is longer than a century. But, still in Famenne, braided channels are observed whereas the stream powers are clearly lower than the threshold proposed in the literature (stream power higher then 100 W/m²). Finally, in Ardenn, when we reach a threshold of 100 W/m², rivers develop an active low sinuosity system in place of an active free meander system. This active low sinuosity system is comparable to a step-pool system. [less ▲]

Located in the southwestern part of Niger, the Dargol basin belongs to the region of Precambrian Liptako. In this area, most of the groundwater resources are stored in fractured aquifers of Precambrian basement. Since the late 1980s, major rural water supply programs were interested in these aquifers and thousands of boreholes were drilled to cover the water needs of the growing population. However, many of them dry up during the dry season, forcing villagers to walk kilometers to fetch water their families. To increase the success rate of drilling, it is important to improve the knowledge on the functioning of these aquifers. The present study is carried out in this context. Its main objective is to identify and characterize fractured reservoirs in order to quantify and improve groundwater resources management methods of in semi-arid. A multidisciplinary methodology is developed to achieve this goal. Its combines lineaments maps, major element geochemistry and isotopic analyzes of drill logs. The lineaments cartography are made from the satellite imagery analysis. It is completed by field measurements, geological and geophysical data analysis. This study helped to understand the influence of the directions of fractures in the yield of the boreholes. New field investigations, particularly piezometric measurements, analyze of water and structural measurements were performed. The chemistry of water in this area revealed three sources of main ions which are from entropic origins, dissolution of gypsum and weathering of silicates minerals. Approximately 19% of boreholes recorded a high content of nitrates exceeding WHO standards (50 mg / l). To better understand the modes of recharge of these fissured aquifers, isotopic approaches were used. Stable isotope ratios (δ18O, δ2H) indicate two groundwater recharge mechanisms: direct recharge waters with little or no rain evaporated and indirect recharge which are infiltration surface water and water from stream channels beds. The analysis of the tritium content of the water indicates that recharge is new at most of the points investigated. In contrast, in area of low levels of tritium, the renewal rate appears to be low or even zero. On the basis of these data, a multi-criteria analysis was performed to produce maps of potential recharge areas and productivity index. These maps are validated using independent data and can be used as a pragmatic tool for water resources management and for future surveys. [less ▲]
