本研究运用"柏林锻炼阶段"模型调查了211名银行员工的体育锻炼行为,并通过检验银行员工的锻炼自我效能变量和社会支持变量在各阶段中的非连续性模式和非线性趋势,考察了该阶段模型的阶段性假说.研究结果没有充分支持上述阶段性假说.未来研究仍需进一步修订该阶段模型. 相似文献

In the current research, we examined whether promoting an inclusive national ingroup that includes both immigrants and nonimmigrants would improve attitudes toward immigrants and immigration among members of receiving societies. We also determined whether one's nation of citizenship and individual differences in social dominance orientation would moderate the effects. Participants were 126 Canadian students and 282 German students, who completed a measure of social dominance orientation and were then asked to respond to a series of questions designed to heighten the salience of national identity (national identity), promote a national ingroup that includes immigrants (common national ingroup), or irrelevant questions (control). The dependent measures included attitudes toward immigrants and immigration, and subtle prejudice toward immigrants. Results revealed that the manipulation of a common national ingroup successfully promoted more positive attitudes toward immigrants and immigration among higher social dominance oriented Canadian participants, but tended to have detrimental effects on the attitudes of higher social dominance oriented German participants. Results are discussed in terms of the importance of considering the context in which groups are situated, as well as implications for developing strategies to promote harmony between immigrants and members of receiving societies. 相似文献

This investigation considers the effects of feedback on memory with an emphasis on retention of initial error responses. Based
on a connectionist model (Clariana, 1999a), this study hypothesized that delayed-retention memory of initial lesson responses
would be greater for delayed feedback compared to immediate feedback, that feedback effects will be greatest with difficult
items, and that there would be a disordinal interaction of feedback timing and item difficulty. High school students (n =
52) completed a computer-based lesson with either delayed feedback, single-try immediate feedback, or multiple-try immediate
feedback. There was a significant difference for type of feedback, with retention test memory of initial lesson responses
greater under delayed feedback than under immediate feedback. Also, instructional feedback effects varied depending on lesson
item difficulty. The findings indicate that a connectionist model can explain instructional feedback effects. 相似文献

Innovation in high technology industries poses considerable challenges, frequently forcing firms to consider using acquisitions as a means of sourcing technology. This paper investigates such behaviour in a major high technology sector, namely the semiconductor industry. The paper focuses on differential effects of technology-related versus nontechnological acquisitions on exploratory and exploitative research and innovation. Most importantly, it confirms the important role of technology-related acquisitions for exploratory innovation. 相似文献
