The United States individualism construct is reflected in 3 factors called (a) Self-Reliance with Competition, (b) Low Concern for Ingroup, (c) Distance from Ingroup (triandis et al., 1988). This study explores the factorial structure of Triandis' items operationalized for Self-Reliance with Competition factor on a sample of Belgian-French speaking University students. A confirmatory factorial analysis on data from 407 subjects suggests that Self-Reliance is distinct from Competition though both factors are not independant. So, it seems that an important aspect of individualism has not necessarily the same meaning by Belgian French-speaking students as by individualists U. S. samples. This confirms that the individualism construct has to be more deeply probed in each country even belonging to close cultural areas. [less ▲]

This article deals with the question of the delimitation of community forest in tropical rainforest as envisaged by the law 94/01 of Cameroon through a case study of the nothern periphery of the Dja Reserve. A methodology of the delimitation of community forest is proposed which confronts on the one hand the legal framework in which they have to be defined (Plan of Zoning and legislation) and on the other hand the effective utilisation of the forest by the ethnic group Badjoué. The results are presented with the aid of maps (spatial occupation by village and summary map). The analysis proceeds by superimposing successive levels of information. The evident inadequacy of two realities lends us to question the methodology which underlies the Zoning Plan. In the light of this information, severals scenarios for the community forest are then sketched out. [less ▲]

The Extreme-UV Imaging telescope has already produced more than 15000 wide-field images of the corona and transition region, on the disk and up to 1.5R_o above the limb, with a pixel size of 2.6\arcsec. By using four different emission lines, it provides the global temperature distribution in the quiet corona, in the range 0.5 to 3*E(6) K. Its excellent sensitivity and wide dynamic range allow unprecedented views of low emission features, even inside coronal holes. Those so-called ``quiet'' regions actually display a wide range of dynamical phenomena, in particular at small spatial scales and at time scales going down to only a few seconds, as revealed by all EIT time sequences of full- or partial-field images. The initial results presented here demonstrate the importance of this wide-field imaging experiment for a good coordination between SOHO and ground-based solar telescopes, as well as for science planning.

Pour analyser l'action des machines de travail du sol, il faut disposer de techniques permettant de quantifier la structure du sol et le microrelief. Dans cet article, la porosité structurale est mesurée en imprégnant d'un mélange résine-colorant des échantillons de sol prélevés de manière non destructive. Une fois les échantillons séchés, la répartition de la porosité est étudiée par analyse d'images et il apparaît que la distribution de fréquence des pores en taille et en forme est caractéristique des façons culturales. Par ailleurs, le microrelief du sol est mesuré à l'aide d'un capteur laser et les données 'hauteur' sont interprétées par analyse de Fourier. La densité spectrale énergétique et la fonction d'autocorrélation rendent très bien compte de l'évolution différenciée du microrelief créé par différents travaux culturaux [less ▲]

L’objectif de cette recherche est de déterminer et d’évaluer le niveau d’observation du phénomène urbain en fonction des résolutions spatiale et spectrale de différents capteurs satellitaires. Les capteurs utilisés sont AVHRR de NOAA, MSS et TM de Landsat, HRV de SPOT et les photographies KVRl000 de KOSMOS. Les échelles sont, dans l’ordre, continentale, régionale et locale. La méthodologie de base est semblable pour les différents niveaux d’observation, mais le résultat des traitements est fonction des échelles utilisées. La procédure comprend les corrections géométriques des images, les classifications dirigées en 6 classes pour AVHRR, en 9 classes pour MSS et en 12 classes pour TM et HRV et le calcul du potentiel urbain. Le potentiel urbain permet de déterminer les axes d’urbanisation, les limites du périmètre urbain ainsi que le réseau des villes à différentes échelles. Les zones d’influente des villes sont déterminées par les polygones de Thiessen pondérés, tandis que les grandes unit& paysagères sont obtenues par classification automatique des images des différents potentiels. L’extraction des axes d’urbanisation est plus efficace avec les données issues de capteurs à haute résolution spatiale tandis que la faible résolution est plus performante pour limiter les zones d’influente des villes, parfois aussi pour la hiérarchie du réseau des villes et surtout pour l’analyse des paysages et des écosystèmes qui les composent.

To estimate actual evapotranspiration on regional scale, seven subcatchments were choosen on fleuve Niger catchment where we have selected stations for representative meteorological measurements. Precipitation values are spatially represented by using Thiessen polygons and Kriging methods and, based on water balance equation, we deduce the actual evapotranspiration term.The goal (objective) of this study is to deduce from the water balance equation the evapotranspiration term, to correlate remote sensing indicators (surface temperature and NDVI) and evapotranspiration data and characterise factors that affect this correlation.

This paper describes the Recreation Index Method as it was developed by the "Faculté universitaire des Sciences agronomiques" during the research project AIR3-CT94-2327 financed by the European Commission. The projects name was "Development and harmonization of monitoring systems for forest resources management in Europe" and the objective was to design a set of inventory systems for forest resources management, applicable in all regions of the European Union for the optimal decision making in the production of multiple goods and services. Several universities and research institutes participated in this research. The "Faculté universitaire des Sciences agronomiques" focused its research on the design of a forest inventory method that enables foresters to assess the recreation function of woodlands. An extensive set of tools already exists for assessing the economic function (woods, production) of forests. Multiple descriptions of volume tables, taper functions, inventory systems, and others were published throughout times and these techniques have become common goods to foresters. However, until now, only very few tools exist for assessing the recreation function of a forest. The Recreation Index Method definitely changes this situation and is a substantial step towards the global evaluation of the recreation value of forests. The method that is described hereafter, produces objective indexes that reflect how well a forest or forest elements meet eh society's demand for recreation: the more a forest corresponds to the publics demand, the higher the recreation index will be. These indexes are calculated from three data sets: 1. Demand: the relative importance that the public attributes to th inventoried items; 2. Offer: an inventory of items in the forest that affect the recreation value of this forest; 3. Appreciation curves and their reference values: the equations that produce the recreation indexes from the inventoried number of items. The method requires an extensive set of data as well as dreadful calculations. The RECRE software was developed to automate the procedures of this method. The computer program stores all the necessary data and easily calculates all the Recreation Indexes. The software and the manual that comes with it are available from the European Community of from the Faculté universitaire des Sciences agronomiques (see address in annexes). Althouth the Recreation Index Method compares offer and demand, it does not take into account the external constrains that influence the offer, the demand, and the interaction between both. Budget and personnel constrains typically influence the offer, while reputation and publicity often modify the demand. Accessibility, extremely high social pressure (especially near cities), vandalism, and even crime are important factors that determine how offer and demand will interact. Considering all those external constrains highly complicates the forest recreation problem. But, before investigating on these external constrains, one may want to know more about the intrinsic value of a forest. That's the important role of the Recreation Index Method. [less ▲]

L'extension récente, après 1960, de Pycnoporus cinnabarinus, en Belgique, au Grand-Duché de Luxembourg et dans les régions limitrophes est analysée à l'aide d'une série chronologique de cartes de distribution. La propagation du champignon semble s'être effectuée à deux "vitesses" : par bonds, sur des distances de plusieurs dizaines de kilomètres, et de proche en proche, au départ de populations voisines. L'analyse de la fréquence et de la fréquence cumulée des récoltes montre deux grandes "vagues" successives d'expansion du champignon. La liste des arbres hôtes est établie ainsi que la fréquence relative du champignon en fonction des hôtes. Les hôtes les plus fréquents sont les bouleaux (Betula alba et Betula pendula), le hêtre (Fagus sylvatica), le sorbier des oiseleurs (Sorbus aucuparia) et les chênes (Quercus robur et Quercus petraea). Les causes de l'extension et des fluctuations des populations du champignon ne sont pas connues avec certitude. Il semble cependant que des facteurs climatiques et le fait que de plus grandes quantités de bois pourrissant soient abandonnées sur les coupes puissent être impliqués. [less ▲]

The paper presents a case study of a seismic refraction survey in Bernburg, Germany. The interpretation was made using the GRM method and phantoming concept. The aim of the survey was to map the depth of the bed-rock over a distance of 2 km. The survey was divided into five linear profiles ranging from 150 to 640 metres in length. The resulting interpreted sections show substantial variations in velocity (1300 to 4500 m/s) and depth (5 to 18 m) of bed-rock. Correlation with existing boreholes shows that the top of the bed-rock is located with an accuracy of the order of 1 metre. [less ▲]

Some methodological aspects of the isotope dilution technique using 15N-leucine as a marker of the endogenous N secretions (choice of the precursor pool, time of blood collection, estimation of the isotopique equilibrium) were studied in pigs. Their effect on the estimation of the ileal endogenous N flow was limited. When 15N-leucine was replaced by 13C-leucine, the ileal endogenous N flow obtained with 13C was much lower than that obtained with 15N (1.4 vs 5.7g N/kg DM intake, respectively). The validity of the 13C-leucine infusion technique is questioned. [less ▲]
