试析高校创新氛围的营造路径

21世纪是一个充满了激烈竞争的世纪,是一个由“创新”引领时代潮流的世纪。国家富强,社会发展,教育进步离不开这一主旋律,更离不开具有创新思维的人才。本文通过探讨营造校园创新氛围的路径,来阐释校园创新氛围对大学生创新思维的养成有着至关重要的作用。     

Effets des pratiques organisationnelles vertueuses sur les comportements citoyens et l’intention de rester dans l’entreprise : le rôle médiateur de l’adéquation personne-organisation

The aims of this study were to explore the effects of virtuous organizational practices on employees’ citizenship behaviors towards the organization and employees’ intention to remain, and to test the mediating role of the person-organization fit in these relationships. A total of 290 employees from different sectors responded to the study. The results revealed that these practices had positive effects on citizenship behavior and intention to stay in the organization and that person-organization fit mediated these relationships partially and completely respectively. The results of this study, devoted to the innovative construct of virtuous organizational practices and its relationship to work attitudes and behaviors, suggest different avenues for research and action, which are discussed.     

Looking back and falling further behind: The moderating role of rumination on the relationship between organizational politics and employee attitudes,well-being,and performance

The current study tested the theoretically relevant, yet previously unexamined, role of rumination on the relationship between politics perceptions and a variety of threat responses. Drawing from Response Styles Theory, it was argued that rumination amplifies the effects of politics by enhancing the influence of negative information on cognition, interfering with problem-solving, and undermining sources of social support. The work stress literature, along with extant politics research, served to identify four variables – job satisfaction, tension, depressed work mood, and employee effort/performance – that served as study outcomes. Across three unique samples, hypothesized relationships were strongly supported, indicating that politics perceptions negatively affected work outcomes of high ruminators, but demonstrate little influence on those who engage in less rumination. Moreover, the nonlinear influences of the focal constructs were considered and the results confirmed atypical relational forms. Contributions, implications for theory and practice, strengths and limitations, and future research directions are described.     

Les gestionnaires tunisiens au cœur de la tourmente postrévolution : entre injustice et empowerment psychologique

The purpose of this research is to comprehend the reasons that arouse employee's psychological empowerment against organizational injustice. Based on this complex problematic, our approach is articulated around two central sectors. We proposed a conceptual framework of the researches related to organizational injustice and psychological empowerment for a better understanding of the mechanisms at work in their genesis. The qualitative exploratory investigation led in the mechanical and electric industrial sector in Tunisia underlined that a set of intra and extraorganizational determinants impact considerably the dynamic between injustice and psychological empowerment. The results clearly underline that contextual particularities are a catalyst of psychological empowerment.     

My Mentor,My Self: Antecedents and Outcomes of Perceived Similarity in Mentoring Relationships

This study examines the antecedents and outcomes of perceived similarity in mentoring relationships in a sample of 82 matched mentor-protégé dyads. Polynomial regression analyses were used to examine the association between actual and perceived similarity. Protégés were more likely to see themselves as similar to their mentors when they and their mentors shared either higher or lower levels of attachment security. However, sharing similar levels of relational self-construal was unrelated to protégés perceptions of similarity with their mentors. Path analyses revealed that protégés reported more organizational and professional commitment when they saw themselves as similar to their mentors, and that these associations were mediated by protégés’ reports of their mentors providing role modeling functions. These findings suggest that the effects of actual mentor-protégé similarity on perceptions of similarity may depend on the shared attribute, and provide further evidence of the importance of perceived similarity to not only mentoring relationships, but also to organizations.     

Effects of team and organizational commitment – A longitudinal study

Retention management, i.e., keeping qualified employees, is a top priority for contemporary organizations. Commitment, and especially team commitment, can be the key to mastering this challenge. There is a lack of longitudinal research concerning the development and the direction of the effects of team commitment over time. In a longitudinal field-study design with three points of measurement, a total of 360 employees in 52 semi-autonomous industrial teams were surveyed over a period of three years. On the one hand, organizational commitment showed stronger effects on organization-related criteria (job satisfaction and intention to leave). These effects were consistent over the three points of measurement. Team commitment, on the other hand, affected team-related criteria (team performance and altruism). Longitudinal analyses confirmed the effects of organizational commitment on job satisfaction and intention to leave, and of team commitment on team performance and altruism. Moreover, these effects increased over time. Theoretical and practical implications of these findings are discussed.     

The costs of today’s jobs: Job characteristics and organizational supports as antecedents of negative spillover

This study examined job characteristics and organizational supports as antecedents of negative work-to-nonwork spillover for 1178 U.S. employees. Based on hierarchical regression analyses of 2002 National Study of the Changing Workforce data and O∗NET data, job demands (requirements to work at home beyond scheduled hours, job complexity, time and strain) had positive relationships, and job resources (autonomy and skill development) and organizational supports (flexible work arrangements and two work-life culture facets) had negative relationships to negative spillover, but not all relationships held when multiple predictors were examined. Organizational supports did not moderate relationships of job characteristics to negative spillover, and relative weights analysis indicated that job characteristics accounted for the majority of explained variance in negative spillover. The findings underscore the importance of job characteristics, and suggest that job characteristics and organizational supports both need to be considered when developing work-life policies intended to reduce employees’ negative work-to-nonwork spillover.     

High-efficiency single-layer organic light-emitting diode based on green fluorescent protein

We have fabricated a molecular organic light-emitting device comprising indium–tin oxide/a molecular organic layer/aluminum in which the organic layer is a green fluorescent protein. The device exhibits peak external quantum and power efficiencies of 8?±?0.2% and 13?±?0.7?lm?W?^??1 at a current of J?=?1.5?A?m^?2, respectively. In addition, the turn-on voltage is 2.5?V for 1?cd?m^?2 and the maximum luminance achieved is 1275?cd?m^?2. This good performance can be explained by the presence of singlet-excited states, leading to a high internal efficiency.     

Ten years of career success in relation to individual and situational variables from the employee development literature

Individual, situational, and socio-demographic variables from the employee development literature were combined with theory and research on career success in a ten-year study of 289 workers from across many jobs and industries in the workforce. Support for employee development by one's employer ten years prior and a trend of increasing/accumulating support contributed to career success, providing the first long-term confirmation of the value to careers from support for development by employers. Proactive personality had unique effects on success not accounted for by a broad array of other variables, strengthening conclusions from prior research about the predictive value of proactive personality which were based on data not controlling for these variables. Finally, achievement goal orientation influenced success in a unique way via “profile effects:” Goal orientation dimensions interacted to predict success, suggesting simple linear effects (e.g. being more learning-oriented) may be inadequate in explaining career success. Implications for future research and practice are discussed.
