双元领导对新员工社会化适应与创新的双路径影响研究

基于双元领导理论、创新理论和组织社会化理论,旨在探究双元领导对新员工社会化适应与创新的影响机制与边界条件。以354名企业新员工为调查对象,运用层次回归分析方法对概念模型进行检验。结果表明:(1)双元领导与新员工创新行为和任务绩效呈显著正相关;(2)角色宽度自我效能感在双元领导与新员工创新行为之间起部分中介作用;(3)角色清晰在双元领导与任务绩效之间起完全中介作用;(4)领导力对双元领导与角色宽度自我效能感和角色清晰之间的正向关系具有显著的强化效应。最后,对研究结果和研究意义进行了讨论并对未来研究做了展望。

Promoting doctoral students' research self-efficacy: combining academic guidance with autonomy support

A diverse sample of doctoral students completed an on-line questionnaire assessing their supervisors' academic, personal and autonomy support and their research self-efficacy. The more task-related help and personal support students received, the more positively they evaluated their supervision. The degree to which supervisors encouraged students to think and act autonomously (autonomy support) was not uniquely associated with students' supervision satisfaction but predicted greater research self-efficacy. A combination of high levels of autonomy and academic support was associated with the highest levels of research self-efficacy, whereas when greater levels of personal support were accompanied by low levels of autonomy support, students reported lower research self-efficacy. These results indicate that effective doctoral supervision involves supporting students to voice and act on their own ideas while simultaneously providing guidance on how to complete research tasks.     

Help-seeking tendencies during early adolescence: An examination of motivational correlates and consequences for achievement

The present study examined the motivational correlates and achievement consequences of students’ help-seeking tendencies during sixth grade (N = 217). Students’ grades were collected from school records at the beginning and end of the school year. Midway through the year students reported on their academic self-efficacy and social demonstration goals; teachers reported on students’ help-seeking tendencies. First quarter grades and academic self-efficacy were positively related to adaptive help seeking and negatively related to avoidant help seeking. In addition, a social demonstration-approach goal was negatively related to adaptive help seeking. Help-seeking tendencies predicted 3rd quarter grades, controlling for 1st quarter grades.     

Developing teaching self-efficacy in research institutions: A study of award-winning professors

The purpose of this study was to assess the sources of award-wining research professors’ (six women; six men) teaching self-efficacy through the framework of Bandura’s (1986) social cognitive theory. Semi-structured interviews revealed that mastery experiences and social persuasions were particularly influential sources of self-efficacy and that these sources tended to be closely related. Professors reported that their self-efficacy had generally stabilized within their first few years of assuming a tenure-track position. Participants framed negative events in adaptive ways that had little cost to their teaching self-efficacy.     

师范生择业效能感问卷的初步编制

为了编制师范生择业效能感问卷,并检验所编制问卷的信度和效度,采用探索性因素分析初步探究理论结构,用验证性因素分析验证理论结构的合理性和正确性。验证结果为:探索性因素分析确定该问卷包括5个因子,全问卷的内部一致性系数为0.96,各分问卷的信度均在0.85以上,各分问卷全问卷得分之间的相关系数在0.859~0.918之间。从而得出结论:编制的师范生择业效能感问卷共包括5个因子,量表具有较好的信效度。     

自助服务技术环境下的顾客参与及其影响因素研究

随着信息技术的发展和互联网的广泛运用,自助服务技术(SSTs)环境下的顾客行为研究已经成为服务营销领域倍受关注的热点.本文以网上旅游预订为例,结合技术接受模型(TAM)和动机理论,系统探讨了角色清晰、动机、自我效能对顾客参与的影响,并得出以下结论:(1)网上旅游预订环境下,顾客参与可以分为信息搜寻、付出努力和信息分享三个维度.(2)感知愉悦、感知行为控制、自我效能和感知易用对顾客参与产生显著的正向影响,其中感知愉悦的影响最大.(3)各前置变量时顾客参与子维度的影响程度各不相同.根据研究发现,本文提出了相关的营销建议以供实际运用.
