Although there is now a considerable literature on gender inequality in education and employment, there is virtually no research on the Careers Service which provides a bridge between the two. Based on a national survey of all Careers Services conducted in 1987, this paper explores the significance afforded to gender discrimination and the nature and content of equal opportunities policies designed to counter it. It draws attention to the differences in meaning which the term ‘equal opportunities’ can have and to the changing context in which equal opportunities policies now operate.  相似文献

Collective efficacy is an important determinant of the motivation of individuals within groups, with increases in collective efficacy producing more effort in a task and greater persistence when faced with failure. To test hypotheses concerning the impact of collective efficacy on effort and persistence, participants (n = 22) were assigned to triads (consisting of the participant and two confederates) and performed three time trials on cycle ergometers. After trial 1, the participants were assigned to either a high or low collective efficacy condition, receiving appropriate bogus performance feedback. All groups received failure feedback after trial 2. Effort was assessed by performance time and maximum heart rate (HRmax) achieved during performance. A 2 (collective efficacy condition) x 3 (trials) analysis of variance with repeated measures on trials revealed significant interaction effects for both performance time and HRmax. Fisher's least significant difference post-hoc tests indicated that, following efficacy manipulation, groups low in collective efficacy significantly reduced both their performance time and HRmax, whereas groups high in collective efficacy maintained performance and HRmax. However, predictions concerning the impact of failure on persistence were not supported. Our results provide partial support for the role of collective efficacy in team sports.  相似文献

This article describes the development of a faculty–librarian collaborative project that integrated discipline-specific information literacy into an upper-level psychology class. The instruction involved a case study technique in order to increase student engagement in a content area while helping students gain needed information literacy skills that meet professional guidelines. We found that employing this approach enhanced instructor ability to more fully and meaningfully engage with students within a more comfortable classroom atmosphere. This method may be easily adapted to other disciplines as it allows for much creativity and selection of course-relevant themes.  相似文献

This article aims at generalizing loxodromic (rhumb line) navigation to conformally flat Riemannian manifolds. We admit space-time dependence of both perturbing vector field and ship’s self-speed. Thereafter, the findings are applied to time-efficient navigation by a variational approach, referring to the local solutions of Zermelo’s navigation problem under arbitrary wind. This yields the corresponding conditions for loxodromic time-minimal and time-maximal navigation in relation to the navigation data. Our research is also illustrated by a two-dimensional example (an oblate ellipsoid), which distinguishes perturbations of different force: weak, critical and strong. It includes numerical simulations and discussion, emphasizing and comparing loxodromic solutions among the minimizing, maximizing and anomalous time extremals.  相似文献

Little research has examined seasonal differences in physical activity (PA) levels among children. Proxy reports of PA were completed by 1,715 parents on their children in Edmonton, Alberta, Canada. Total PA (TPA) minutes were calculated, and each participant was classified as active, somewhat active, or inactive. Logistic regression models were conducted to examine associations between PA status and seasons. Significant seasonal differences were observed for TPA, weekday PA, weekend PA, and active play. Children were significantly more likely to be physically active in the summer and spring and somewhat physically active in the summer and fall, relative to winter Children living in cold climates are less likely to be physically active in the winter.  相似文献

Collective efficacy research has begun to progress from simply trying to verify the relationship between collective efficacy and performance to examining the mechanisms through which collective efficacy impacts on performance. To test hypotheses concerning the impact of collective efficacy on group goal selection and commitment, 24 participants were assigned to triads (consisting of the participant and two confederates) and performed two time-trials on cycle ergometers. Before each trial, the participants were asked to select both a finishing time and position goal for their group and to indicate their commitment towards these goals. After trial 1, the participants were assigned to either a high or low collective efficacy condition and received appropriate bogus performance feedback. Analysis of variance and post-hoc tests revealed that participants in the low collective efficacy group significantly reduced both finishing time and group position goals from trial 1 to trial 2, whereas participants in the high collective efficacy group maintained their goals. These results provide support for Bandura's suggestions concerning the mechanisms through which collective efficacy impacts upon performance.  相似文献

Early research experiences must be made available to all undergraduate students, including those at 2-yr institutions who account for nearly half of America''s college students. We report on barriers unique to 2-yr institutions that preclude the success of an early course-based undergraduate research experience (CURE). Using a randomized study design, we evaluated a CURE in equivalent introductory biology courses at a 4-yr institution and a 2-yr institution within the same geographic region. We found that these student populations developed dramatically different impressions of the experience. Students at the 4-yr institution enjoyed the CURE significantly more than the traditional labs. However, students at the 2-yr institution enjoyed the traditional labs significantly more, even though the CURE successfully produced targeted learning gains. On the basis of course evaluations, we enhanced instructor, student, and support staff training and reevaluated this CURE at a different campus of the same 2-yr institution. This time, the students reported that they enjoyed the research experience significantly more than the traditional labs. We conclude that early research experiences can succeed at 2-yr institutions, provided that a comprehensive implementation strategy targeting instructor, student, and support staff training is in place.  相似文献
