基于锻炼心理学领域中的"从无活动到保持活动的4步骤模型"(Four Steps from In-activity to Activity;FIT模型),以3 807名大学生为研究对象,探讨了大学生身体活动阶段变化与健康状况变量(身体体质、主观良好感、健康满意度和不适感)之间的关系。研究结果表明,处于活动阶段的个体,其健康状况水平均好于处于不活动阶段的个体;在3个活动阶段上,处于保持期(即长期保持规律性身体活动)的个体,其健康状况水平均好于处于探索期和波动期的个体;人口统计学变量和健康状况变量共同解释了17.6%的阶段方差变异(F=108.48,P<0.05)。验证了FIT模型中大学生身体活动阶段变化与健康状况之间的相关关系,为今后运用FIT模型诊断大学生身体活动变化阶段及其相应健康状况提供了实证依据。 相似文献

The effects of systematically varied teacher verbal and nonverbal evaluative behavior upon student willingness to self-disclose were studied within an experimental microlesson. Subjects were 126 sixth-grade students who were removed from their classrooms to participate in a vocabulary lesson with one of the four experimental teachers (two male and two female). Within each experimental condition, the teacher employed one of four evaluative styles: (1) verbally and nonverbally positive, (2) verbally positive and nonverbally negative, (3) verbally negative and nonverbally positive, or (4) verbally and nonverbally negative. The data analysis indicated that teachers' verbal behavior influenced self-disclosure. The magnitude of student self-disclosure scores was a direct function of the positiveness of teacher verbal behavior. Nonverbal behavior also influenced self-disclosure, interacting with student sex. This effect varied across individual teachers, however, and no consistent pattern was evident. 相似文献

We examined the role of social support in turnover intention among new teachers. First, we tested and found evidence for a direct negative relationship between social support and turnover intention. Second, we tested the social support buffer hypothesis, and found that teachers with higher social support had lower turnover intention in the face of higher workload, compared to teachers with lower support. Third, we examined a mediational hypothesis, and found that social support acts indirectly, through job satisfaction in relation to turnover intention. These findings suggest that social support can be a valuable resource for new teachers. 相似文献

Video is a medium that has passed through a progression of technical advances including the invention of videotape, the incremental refinements to laser videodisc technologies, and the arrival of digital imaging technologies such as CD-ROM, DVD, and the Web's video streaming. Today, video is firmly established as a convenient and effective medium for conveying medical information. One result of these developments is that medical reference librarians can expect to encounter information requests and professional tasks that will require an understanding of these wide-ranging and differing video technologies. 相似文献

The current study tests whether media consumption is associated with negative intergroup emotions toward Blacks, Latinos, and Asians and whether media use indirectly influences intergroup emotions via threat perceptions. We do so using a two-study survey design. Results from Study 1 indicated that media consumption is associated with anger toward Latinos and Asians but not anger toward Blacks. We also found that media use was associated with anxiety toward Blacks, Latinos, and Asians. Results from Study 2 indicated that media use indirectly influences anger and anxiety toward Blacks and Latinos through perceptions of threat. Media consumption did not indirectly influence anger and anxiety toward Asians, though perceptions of threat did directly influence intergroup emotions toward this group. The discussion highlights the important, but negative, role of media in intergroup processes. 相似文献

This study investigated student teachers’ efficacy beliefs, collective teacher efficacy beliefs, and perceived cooperating teachers’ efficacy beliefs. These student teacher beliefs were examined with the focus on context, primarily the school setting (i.e., rural, suburban, and urban), to determine whether setting played a role in the development of the student teachers’ efficacy beliefs. The research participants included 102 student teachers. All three setting groups exhibited significant increases in teachers’ sense of efficacy following student teaching. Urban student teachers exhibited significantly lower perceived collective efficacy. Perceived cooperating teachers’ efficacy was predictive of and positively related to the student teachers’ post-TSES scores. 相似文献
