This prospective study examined romantic partner selection and socialization among a sample of 78 young adolescents (6th–8th graders). Independent assessments of adolescent and romantic partner adjustment were collected before and after relationships initiated via peer nomination and self‐report. Prior to their relationship, adolescents and partners were significantly alike on popularity, physical attraction, and depressive symptoms. Controlling for initial similarity, partners’ popularity, depressive symptoms, relational aggression, and relational victimization significantly predicted changes in adolescents’ functioning in these areas over time. However, the magnitude and direction of change varied according to adolescents’ and partners’ prerelationship functioning. In general, adolescents who dated high‐functioning partners changed more than those who dated low‐functioning partners, and partner characteristics predicted greater change among low‐ versus high‐functioning adolescents. Results were consistent even when controlling for best friend characteristics. The current findings are among the first to demonstrate unique contributions of romantic partner characteristics to adolescents’ psychosocial functioning. 相似文献

The emphasis on competitiveness and the knowledge-based economy in European policymaking has resulted in a heightened focus on monitoring and steering the science system, particularly through metric-based instruments. Policymakers’ general aims of fostering excellent research and breakthroughs are shared by researchers as well; however, below the surface is a paradox that is rarely discussed. The political system and the science system understand and pursue these concepts and objectives differently. Through two case studies on high-performing university-based research environments in Denmark and Sweden, this article uncovers the ways in which highly successful researchers often behave in ways that run counter to policy steering attempts. They do this by shielding themselves and their research group from steering pressures originating in the political system. Using Luhmann’s systems theory, the cases demonstrate why the relationship between the science system and the political system needs to be understood as a horizontal rather than a vertical relationship, and using concepts from organizational theory, provides a model and terminology for identifying and analyzing the types of mechanisms and strategic responses that the science system uses to shield itself from political steering pressures. 相似文献

Intake of a 0.15% saccharin solution was suppressed when it was followed by a 32% sucrose solution in brief daily pairings. With equal access durations to the two solutions, intervals of intermediate duration (2 or 3 min) produced a larger contrast than more extreme intervals (1 or 10 min). There was no evidence of inhibition of delay with the 10-min interval (Experiments 1A and 1B). When access times were asymmetrical, longer access time to the first solution reduced contrast, whereas longer access time to the second solution enhanced contrast (Experiment 2). Contrast was greater when the two solutions were presented at consistent and separate spatial locations than when location was changed randomly or when both solutions were presented in sequence at the same location. However, a degree of contrast occurred in all conditions (Experiment 3). Experiment 4, conducted with the solutions in opposite arms of a T-maze, showed that anticipatory approach to the location correlated with the 32% sucrose solution developed prior to lick suppression on the saccharin solution. However, within daily sessions, there was a reliable increase in contrast without correlated changes in anticipatory-approach behavior. Access-time effects were attributed to altered reward values, whereas spatial-separation effects suggest that goal-directed responses contribute to, but do not cause, anticipatory contrast. 相似文献

U.S. Supreme Court opinions have left some doors open for institutions to build the kinds of diverse student populations that are known to enrich the learning of all students. But simply inviting diverse students through those doors is not doing nearly enough. 相似文献

Conclusion As culture is at the heart of meaning making, it warrants exacting attention in the systemic design process. As Gustafson
& Powell (1991) point out, too often models are not tested for validity and reliability. It is for this reason that we emphasize
that research must critically evaluate this expanded ADDIE model.
As technology enables us to increase our interaction with the peoples of the world, we are enriched by the incessant shifts
in our own cultural paradigms. Attention to this cultural dynamism and incessant interplay leads to both improved designs
and improved designers. As instructional designers, we must be able to critically analyze our learner’s cultures and allow
it to strengthen the instructional design process. In this way we address our ethical commitment to creating culturally sensitive
products.

Abstract A home‐based reinforcement (H‐BR) programme was carried out in a secondary school to increase rule‐following and work completed by two groups of disruptive students. Of particular interest was whether the positive effects of the programme on target students would ‘spill‐over’ to equally disruptive control students in the same classes. The results showed highly significant improvements in the work and behaviour of both sets of target students but positive ‘spill‐over’ effects on controls were only apparent in one of the classes. Possible explanations for this are discussed. It is concluded that the already considerable value of H‐BR programmes in secondary schools as minimal intervention techniques would be enhanced even more if ‘spill‐over’ effects on non‐targeted, classroom sub‐groups could be planned for, rather than hoped for. 相似文献

Cross-Racial Interaction Among Undergraduates: Some Consequences, Causes, and Patterns 总被引:1,自引:0,他引:1
This study utilized a national longitudinal data set of college students to examine the educational relevance of cross-racial interaction and how campuses can best structure such opportunities. The general pattern of findings suggests that cross-racial interaction has positive effects on students' intellectual, social, and civic development. The results show that institutions could enhance such experiences by enrolling larger proportions of students of color and by offering students more opportunities to live and work part-time on campus. While these findings apply uniformly to white students, the frequency of cross-racial interaction does not always follow an expected path of steady gains for students of color as the student body becomes increasingly more diverse. Implications of the findings are discussed. 相似文献
