Il est évalué qu’entre 15 et 40 % des élèves surdoués performent à des niveaux inférieurs à leur potentiel (Seeley, 1994). Récemment, plusieurs chercheurs se sont plongés dans ce phénomène en tentant de l’expliquer. Par contre, une seule équipe de recherche s’est attardé sur l’impact des climats socioéducatifs sur la performance des surdoués, alors que ce lien est bien existant chez les jeunes non-doués. Cette recherche vise à explorer la relation possible entre les climats socioéducatifs, l’environnement familial et la performance scolaire chez les jeunes surdoués, afin de combler ce manque dans la littérature. Afin d’atteindre cet objectif, un échantillon de 1 885 participants de 3e secondaire provenant de la base de donnée de l’évaluation du programme SIAA furent étudiés afin de créer un modèle présentant l’effet des environnements sur la performance des jeunes surdoués, médié par la motivation. Nos résultats suggèrent que l’impact des environnements socioéducatifs et familiaux sur la performance des jeunes surdoués est minime, bien qu’il soit majeur chez les jeunes non-doués.

Several writings explore the organizational innovation and relate its effect on the organizational performance. However, few studies, on the one hand, take into account the technical innovation and the management innovation as dimensions of organizational innovation; and on the other hand, they use these dimensions to analyze its effect on the organizational performance.In this paper, the authors analyze the influence of innovation -including the twodimensions mentioned- on organizational performance. Furthermore, the authors examinethe behavior of organizational characteristics as a moderator variable of this relationship. The study was applied to service sector companies. The results indicate that innovationand technical innovation have an influence on the organization performance, while management innovation does not. This strengthens the argument that asserts companies need to improve the low perception they have about the importance of management innovation,for better performances.

Two studies investigated the degree to which the relationship between rapid automatized naming (RAN) performance and reading development is driven by shared phonological processes. Study 1 assessed RAN, phonological awareness, and reading performance in 1010 7- to -10 year-olds. Results showed that RAN deficits occurred in the absence of phonological awareness deficits. These were accompanied by modest reading delays. In structural equation modeling, solutions where RAN was subsumed within a phonological processing factor did not provide a good fit to the data, suggesting that processes outside phonology may drive RAN performance and its association with reading. Study 2 investigated Kail’s proposal that speed of processing underlies this relationship. Children with single RAN deficits showed slower speed of processing than did closely matched controls performing normally on RAN. However, regression analysis revealed that RAN made a unique contribution to reading even after accounting for processing speed. Theoretical implications are discussed.

This paper describes a region-based algorithm for deriving a concise description of a first order optical flow field. The algorithm described achieves performance improvements over existing algorithms without compromising the accuracy of the flow field values calculated. These improvements are brought about by not computing the entire flow field between two consecutive images, but by considering only the flow vectors of a selected subset of the images. The algorithm is presented in the context of a project to balance a bipedal robot using visual information.

We study the contemporaneous relationship between the intensity of the Indian Summer Monsoon (ISM) and runoff in the major rivers of the Aral Sea basin (Amudarya, Syrdarya) and some of their subcatchments. To this end, we use All-India rainfall (AIR) data, CRU surface observations of precipitation and temperature, ERA40 atmospheric data, and natural discharge data corrected for human interference. We show that there is a highly significant positive correlation between ISM intensity and Amudarya runoff. This finding cannot be explained by the spill-over of ISM precipitation over the Hindu Kush into the Amudarya basin. Instead, we suggest that the observed co-variability is mediated by tropospheric temperature variations due to fluctuations in the ISM intensity. These variations are known to be due to Rossby-wave propagation in response to condensational heating during monsoon precipitation. We hypothesise that the corresponding anomalies in surface temperatures imply anomalies in meltwater formation.

Retail organisations have often been cited as being at the forefront of corporate real estate management. This research found that the retail sector can be characterised by diversity both in terms of the degree to which organisations are vertically integrated and in terms of the range of modes of retailing they engage in. This in turn led to highly diverse real estate portfolios. Given this diversity it may be surprising that the over riding strategy which the vast majority of sample firms adopted was focused on supporting the core retail activity. However the way in which they implement this strategy, again reflected the diversity in the sector. In terms of the future, the senior real estate managers were focusing on the medium term particularly looking at the way change would impact their functional strategy. This study provides a snap-shot of current practice and contributes to the debate however it also recognised that there is a need to answer the more fundamental questions.
