This study examines gender differences in the variability of student performance in reading, mathematics and science. Twelve databases from IEA and PISA were used to analyze gender differences within an international perspective from 1995 to 2015. Effect sizes and variance ratios were computed. The main results are as follows. (1) Gender differences vary by content area, students’ educational levels, and students’ proficiency levels. The gender differences at the extreme tails of the distribution are often more substantial than the gender differences at the mean. (2) Exploring the extreme tails of the distributions shows that the situation of the weakest males in reading is a real matter of concern. In mathematics and science, males are more frequently among the highest performing students. (3) The “greater male variability hypothesis” is confirmed. [less ▲]

In today’s changing environment, SMEs must strengthen their competitiveness and credibility with all their external partners. So to survive and prosper, managers need adequate management practices in order to provide relevant accounting information. This paper examines the effect of profile of manager on management accounting practices which was defined in terms of traditional management accounting, modern management accounting and management accounting practices related to export. As to the profile of manager, it is defined by age, type of training and experience. To validate the hypotheses, a multiple linear regression method is used. The data is collected by questionnaire from 221 Tunisian manufacturing SMEs. The findings indicate that the profile of manager affect in part the use of management accounting practices. [less ▲]

Qu’on le veuille ou non, les habitants de la planète sont désormais appelés à y côtoyer constamment et intensément des personnes qui ne parlent pas, qui ne pensent pas et qui ne vivent pas comme eux. Entre les deux attitudes extrêmes de chercher à supprimer l’Autre, par le génocide ou l’uniformisation, ou de le redouter et de se replier sur soi, chaque citoyen et chaque communauté doivent inventer une nouvelle économie des rapports à soi comme aux autres. Il faut d’abord prendre la mesure que l’individu, manifestement en crise, est lui-même pluriel et doit gérer son identité en perpétuel devenir et (re)construction ; ensuite, que le groupe devient un espace à géométrie variable que les contacts, les échanges, les voyages ne cessent de remodeler, et dont la médiation assure le plus ou moins bon fonctionnement. Cet ouvrage interroge, à partir de points de vue linguistiques et culturels, les conditions actuelles du communiquer et du vivre avec les autres, les nouvelles modalités d’être soi, et il analyse pour ce faire aussi bien l’actualité que l’histoire, la réalité que les mythes, de Babel mais aussi de Frankenstein, dont l’époque contemporaine est en train de célébrer le retour.

Methylmercury MeHg is highly immunotoxic and can alter the health status of the harbour seal, Phoca vitulina, from the North Sea. To investigate the mechanism of MeHg-induced toxicity in harbour seal lymphocytes, ConA-stimulated peripheral blood leucocytes were exposed in vitro to sub-lethal concentrations of MeHgCl (0.2, 1 and 2 µM) for 72h, and then analysed for their viability and ultrastructure. After 72h of incubation, cells were counted with a propidium iodide staining technique, a metabolic MTS assay was performed, and cells exposed to 1 µM MeHgCl were observed by transmission electron microscopy (TEM). Alive cell numbers decreased with increased MeHgCl concentrations. In presence of ConA and 1µM of MeHgCl, TEM images revealed a higher frequency of apoptotic cells. Exposed cells displayed condensation of the chromatin at the nuclear membrane and mitochondrial damages. The results suggest that in vitro MeHgCl induced apoptosis in harbour seal lymphocytes through a mitochondrial pathway. [less ▲]

Harbor seals are exposed to increasing pressure caused by anthropogenic activities in their marine environment. Persistent organic pollutants (POPs) and trace elements are hazardous contaminants which accumulate in tissues of harbor seals. POPs and trace elements can negatively affect the immune-system and have been reported e.g. to increase susceptibility to viral infections in seals. Biomarkers of the xenobiotic metabolism, cytokines and heat-shock-protein as cell mediators of the immune-system were established to evaluate the impact of environmental stressors on harbor seals. Harbor seals (n=54) were captured on sandbanks in the North Sea during 2009 to 2012. Medicals including hematology were performed, RNAlater blood samples were taken and analyzed using quantitative Polymerase Chain Reaction. Normalized transcript copy numbers were correlated to hematology and POP concentration in blood, and trace metals in blood and fur. [less ▲]

The Hazel dormouse (Muscardinus avellanarius) is a habitat specialist that prefers dense shrub and tree vegetation and needs a high diversity of food plants on a limited area. Due to habitat degradation and fragmentation the Flemish distribution area of this critically endangered species has been reduced to the eastern part of the municipality of Voeren, where it forms a cross-border population with the Dutch Hazel dormice. Since 2003 the Mammal Working Group of Natuurpunt studies the remaining Flemish population to find out more about population parameters, habitat use, the influence of habitat quality and management actions. In 2007 a standardised monitoring started by counting autumnal nests along fixed transects. In 2013 an intensive capture-mark-recapture study was set up based on nest box and nest tube checks and live-trapping on custom made hanging platforms; also a first test with radiocollars took place. The information gathered from the combination of all these methods will be used to validate the monitoring method and to formulate better protection measures. First results show that late summer and autumn should not be considered as the main reproduction period, at least not in an early year like 2014 when first young were already born at the beginning of May. Hazel dormice do not only cross significant barriers like the railway during dispersal, but also do this regularly during their nightly movements within their home range. Expansion of the population on a location with sufficient connectivity seems to be hampered by a too low population density resulting from insufficient habitat quality and (in this case) a high predation pressure by house cats. On the scale of the Meuse-Rhine Euregion, genetic analyses carried out by the University of Liège reveal four genetically isolated clusters, for which a vision to interconnect these was computed in the Interreg-project ‘Habitat Euregio’.

Recent studies suggest common neural substrates involved in verbal and visual working memory (WM), interpreted as reflecting shared attention-based, short-term retention mechanisms. We used a machine-learning approach to determine more directly the extent to which common neural patterns characterize retention in verbal WM and visual WM. Verbal WM was assessed via a standard delayed probe recognition task for letter sequences of variable length. Visual WM was assessed via a visual array WM task involving the maintenance of variable amounts of visual information in the focus of attention. We trained a classifier to distinguish neural activation patterns associated with high- and low-visual WM load and tested the ability of this classifier to predict verbal WM load (high–low) from their associated neural activation patterns, and vice versa. We observed significant between-task prediction of load effects during WM maintenance, in posterior parietal and superior frontal regions of the dorsal attention network; in contrast, between-task prediction in sensory processing cortices was restricted to the encoding stage. Furthermore, between-task prediction of load effects was strongest in those participants presenting the highest capacity for the visual WM task. This study provides novel evidence for common, attention-based neural patterns supporting verbal and visual WM. [less ▲]

Almost all catchments plot within a small envelope around the Budyko curve. This apparent behaviour suggests that organizing principles may play a role in the evolution of catchments. In this paper we applied the thermodynamic principle of maximum power as the organizing principle. In a top-down approach we derived mathematical formulations of the relation between relative wetness and gradients driving runoff and evaporation for a simple one-box model. We did this in an inverse manner such that when the conductances are optimized with the maximum power principle, the steady state behaviour of the model leads exactly to a point on the asymptotes of the Budyko curve. Subsequently, we added dynamics in forcing and actual evaporations, causing the Budyko curve to deviate from the asymptotes. Despite the simplicity of the model, catchment observations compare reasonably well with the Budyko curves subject to observed dynamics in rainfall and actual evaporation. Thus by constraining the model with the asymptotes of the Budyko curve we were able to derive more realistic values of the aridity and evaporation index without any calibration parameter. Future work should focus on better representing the boundary conditions of real catchments and eventually adding more complexity to the model. [less ▲]
