À l'instar de la Réforme de l'éducation qui a lieu actuellement au Québec, deux éléments viennent alimenter le but et la raison d'être de cette recherche: l'abandon des cours de choix de carrière dans la grille-matière et le développement des compétences informatiques. Ces deux éléments relèvent des compétences transversales devant être construites par l'élève. L'objectif de cette recherche était de cerner l'efficacité du recours à des environnements informatiques en tant qu'outils de construction de compétences spécifiques et ainsi proposer aux jeunes une nouvelle méthode pour acquérir leur autonomie vocationnelle. L'échantillon était composé d'élèves de quatrième et cinquième secondaire. Suite aux traitements des données et aux analyses du discours des élèves, nos résultats démontrent comment les participants ont atteint certaines compétences transversales d'ordre méthodologiques et intellectuelles salutaires à leur choix de carrière. L'apport des technologies de l'information et des communications a été démontré et des pistes de recherches subséquentes ont été suggérées.

L'approche orientante qui est présentement implantée dans les écoles du Québec vise à favoriser l'implication des parents dans l'orientation de leurs enfants. La Suisse a pour sa part des méthodes qui répondent déjà à cet objectif. Afin de fournir une liste d'activités à privilégier pour la mise en oeuvre de l'approche orientante au Québec, 335 questionnaires ont été distribués à des parents du canton de Fribourg (Suisse). Ces derniers devaient indiquer les activités qui leur avaient été proposées au cours des études secondaires de leurs enfants, en plus de fournir leur degré de satisfaction à l'égard de celles-ci. Les résultats observés traduisent plusieurs suggestions d'activités permettant d'informer et d'impliquer davantage les parents dans l'orientation de leurs enfants.

Salespeople play a pivotal role in promoting new products. Therefore, managers need to know what control mechanism (i.e., output-based control, behavior-based control, or knowledge-based control) can improve their salespeople's new product sales performance. Furthermore, managers may be able to assist salespeople in performing better by having a strong market orientation. The literature has been inconsistent regarding the effects of sales management control mechanisms and has not yet incorporated market orientation into a sales management control framework. The current study surveyed 315 Taiwanese salespeople from publicly traded electronics companies with the aim of contributing to the sales management literature. The results show that sales management controls can directly affect salespeople's innovativeness, which, in turn, affects new product sales performance. However, sales management controls cannot affect performance directly. Furthermore, market orientation can positively moderate the relationship between salespeople's innovativeness and new product sales performance.

This paper extends original insights of resource-advantage theory (Hunt & Morgan, 1995) to a specific analysis of the moderators of the capabilities-performance relationship such as market orientation, marketing strategy and organizational power. Using established measures and a representative sample of UK firms drawn from Verhoef and Leeflang’s data (2009), our study tests new hypotheses to explain how different types of marketing capabilities contribute to firm performance. The application of resource-advantage theory advances theorising on both marketing and organisational antecedents of firm performance and the causal mechanisms by which competitive advantage is generated.

Understanding the determinants of international performance, and in particular, export performance is key for the success of international companies. Research in this area focuses mainly on how resources and capabilities allow companies to gain competitive advantage and superior performance in external markets. Building on the Resource-Based View (RBV) and the Dynamic Capabilities Approach (DCA), this study aims at analysing the effect of intangible resources and capabilities on export performance. Specifically, this study focuses on the proposition that entrepreneurial orientation potentiates the attraction of intangible resources, namely relational and informational resources. Moreover, we propose that these resources impact export performance both directly and indirectly through dynamic capabilities.

This study aims at investigating the influence that entrepreneurial orientation has on export performance of Portuguese footwear small and mediumenterprises (SMEs). Therefore, a quantitative methodological approach was used, conducting a descriptive, exploratory and transversal empirical study, having applied a questionnaire to a sample of Portuguese companies exporting footwear. The research results suggest that entrepreneurial orientation enhances export performance in the analysed SMEs, particularly innovation and proactiveness, through the amount of funds invested, human resources dedicated to this activity, number of new products or services introduced in the market and frequent change in product lines or services and materialization of a long-term perspective, which is accompanied by innovative activities or new businesses. Therefore, the findings sustain the necessity to invest in entrepreneurial orientation as a strategic determinant, which contributes to the growth of small firms in foreignmarkets. Finally, the main limitation of this study is related to the sample size, since it was difficult to find companies willing to collaborate with this kind of research.

Gravity and light are major factors shaping plant growth. Light perceived by phytochromes leads to seedling deetiolation, which includes the deviation from vertical hypocotyl growth and promotes hypocotyl phototropism. These light responses enhance survival of young seedlings during their emergence from the soil. The PHYTOCHROME KINASE SUBSTRATE (PKS) family is composed of four members in Arabidopsis (Arabidopsis thaliana): PKS1 to PKS4. Here we show that PKS4 is a negative regulator of both phytochrome A- and B-mediated inhibition of hypocotyl growth and promotion of cotyledon unfolding. Most prominently, pks4 mutants show abnormal phytochrome-modulated hypocotyl growth orientation. In dark-grown seedlings hypocotyls change from the original orientation defined by seed position to the upright orientation defined by gravity and light reduces the magnitude of this shift. In older seedlings with the hypocotyls already oriented by gravity, light promotes the deviation from vertical orientation. Based on the characterization of pks4 mutants we propose that PKS4 inhibits changes in growth orientation under red or far-red light. Our data suggest that in these light conditions PKS4 acts as an inhibitor of asymmetric growth. This hypothesis is supported by the phenotype of PKS4 overexpressers. Together with previous findings, these results indicate that the PKS family plays important functions during light-regulated tropic growth responses

La nouvelle organisation sociale du travail du début du 21e siècle pose une série de questions et lance de nombreux défis aux spécialistes de l'accompagnement en orientation professionnelle. Compte tenu de la mondialisation du conseil en orientation, c'est dans un cadre international que nous avons décidé d'aborder ces questions, puis de formuler des réponses potentiellement innovantes. Cette approche permet d'éviter les difficultés que soulève la création de modèles et de méthodes dans un pays donné en tentant ensuite de les exporter dans d'autres, où ils doivent être adaptés pour être utilisés. Cet article présente le premier résultat tangible de cette collaboration : un modèle et des méthodes d'accompagnement des personnes. Le modèle « Construire sa vie », destiné à des interventions d'accompagnement en orientation se fonde sur cinq présupposés concernant les personnes et leur vie professionnelle : des possibilités liées aux contextes, des processus dynamiques, une progression non linéaire, des perspectives multiples et des configurations individuelles. En partant de ces présupposés, nous avons bâti un modèle en contexte, se réclamant de l'épistémologie du constructionnisme social, reconnaissant en particulier que les connaissances et l'identité d'un individu sont le produit d'interactions sociales et que le sens est co-construit, via la médiation du discours. Le cadre général « construire sa vie » s'appuie sur les théories de la construction de soi (Guichard, 2005) et de la construction des parcours professionnels (Savickas, 2005), qui décrivent les conduites d'orientation et leurs développements. Ce cadre concerne toute la vie, il est holiste, tient compte des contextes et est préventif.

The superconducting transition temperature Tc of metallic glasses ZrxFelOO-x (x=80, 75), Zr75(NixFelOO-x)25 (x=75, 50, 25), and CU2SZr75 were measured under quasi-hydrostatic pressure up to 8 OPa (80kbar). The volume (pressure) dependence of the electron-phonon coupling parameters Aep for CU25Zr75 was calculated using the McMillan equatio11. Using this volume dependence of Aep and the modified McMillan equation which incorporates spin-fluctuations, the volume dependence of the spin fluctuation parameter, Asf, was determined in Zr75Ni25, ZrxFelOO-x , a11d Zr75(NixFelOO-x)25. It was found that with increasing pressure, spinfluctuations are suppressed at a faster rate in ZrxFe lOO-x and Zr75(NixFelOO-x)25, as Fe concentration is increased. The rate of suppression of spin-fluctuations with pressure was also found to be higher in Fe-Zr glasses than in Ni-Zr glasses of similar composition.
