The present study investigates the joint effect of the quantity and quality of out-of-school activities (i.e., employment and leisure) on academic outcomes (i.e., well-being, study attitude, and academic performance) among 230 undergraduates. A series of hierarchical regression analyses show that spending too much time in both employment and leisure activities has negative relations with undergraduates’ academic outcomes. Work-study interference fully mediated the effect of time engagement in student employment on students’ reported well-being. These findings support a conflict perspective on multiple role engagement. However, results also show positive effects of activities depending on job demand and autonomy and level of autonomous motivation to engage in these activities. We conclude that out-of-school activities can be beneficial for students’ academic outcomes and preparation for the labor market when perceived as relevant for their academic study and performed in a balanced, autonomous way. 相似文献

The relationship between objective and perceived fit with academic major, adaptability, and major-related outcomes 总被引:2,自引:0,他引:2

This study examined the effects of fit with college major on major commitment, GPA, college satisfaction, and changing one’s major. We further examined how individual adaptability may moderate the importance of fit on these outcomes. College students (N = 198; 160 women and 38 men; mean age = 19.14 years) completed an interest inventory used to assess objective fit with major, and also indicated their perceived fit with major. Results revealed little correlation between perceived fit and objective fit, with differential relationships to these outcomes. Perceived fit showed stronger positive correlations with affective major commitment and academic self-efficacy than did objective fit. Regarding the moderating role of adaptability, individuals higher in adaptability reported higher institutional satisfaction when there was lower perceived fit. Adaptability also had a main effect on major-related outcomes above and beyond the effects of fit. Practical and theoretical implications of these results are discussed. 相似文献

Previous research has focused on enhanced processing as a response to causal uncertainty (CU), but relatively little empirical attention has been given to how CU is activated and the temporal unfolding of this activation. The current research investigates the counterintuitive idea that people inhibit causal uncertainty immediately after its activation. We find that this inhibition weakens over time. Study 1 demonstrates this inhibition effect with self-report uncertainty. Study 2 demonstrates this effect with an implicit accessibility measure. Temporary inhibition of uncertainty may be a general response when uncertainty is activated. 相似文献

The main purposes of this study are to examine whether multisource feedback ratings predict leaders' organizational goal performance, and whether the relationships are consistent across the two rating purposes (developmental, administrative), two leadership dimensions behaviors (Consideration, Initiating Structure), and three rating perspectives (supervisor, self, and ‘other’ raters, i.e., peers and subordinates). Leaders (n=396) in a large organization in the transportation industry participated in two multisource feedback programs, the first for developmental purposes and the second 8 months later for administrative purposes. Approximately 1 month later, they were rated by their supervisor on their effectiveness in attaining five organizational performance goals (financial, safety, customer satisfaction, employee satisfaction, diversity). Results revealed that both developmental ratings and administrative ratings uniquely predicted leaders' goal performance. However, both leadership dimension and rater perspective moderated these relationships. Leadership behaviors associated with Consideration were stronger predictors of goal performance for supervisor ratings, whereas behaviors associated with Initiating Structure were stronger predictors of goal performance for self and other ratings. 相似文献

Hispanic individuals in the U.S. have been disproportionately impacted by HIV/AIDS, yet little is known regarding the neuropsychological sequelae of HIV within the Hispanic population. This study characterized neuropsychological (NP) test performance of HIV+ English-speaking Hispanic participants (n = 51) and investigated the combined roles of sociocultural factors (e.g., ethnicity, socioeconomic status [SES] proxy, and reading level) on NP test performance among our HIV+ Hispanic and non-Hispanic White participants (n = 49). Results revealed that the pattern of NP impairment in HIV+ Hispanic participants is consistent with the frontal-striatal pattern observed in HIV-associated CNS sequelae, and the overall prevalence of global NP impairment was high compared to previous reports with more ethnically homogeneous, non-Hispanic White cohorts. Multivariate prediction models that considered both sociocultural factors and CD4 count revealed that reading level was the only unique predictor of global NP functioning, learning, and attention/working memory. In contrast, ethnicity was the only unique predictor of abstraction/executive functioning. This study provides support for the use of neuropsychological evaluation in detecting HIV-associated NP impairment among HIV+ Hispanic participants and adds to the growing literature regarding the importance of considering sociocultural factors in the interpretation of NP test performance. 相似文献

Although it is assumed that there are negative social consequences for individuals missing visible front teeth, no study of the way in which edentulous individuals were perceived in a social context and the potential social repercussions could be located. This initial study concerned college students' perceptions of individuals missing visible upper front teeth. 200 volunteers, 19 to 50 years of age (M = 20.6, SD = 4.4), rated five photographs depicting tooth presence or absence, from a full dentition to missing as many as four upper front teeth, on social traits including attractiveness, health status, educational attainment, satisfaction with life, active social life, aggressiveness, intelligence, trustworthiness, amount of caring, friendship, dating, and likelihood to live as a neighbor. Analysis suggested a person missing visible teeth was more negatively perceived on all social traits than a person with full dentition. Results were strongest when students were proposed to be linked to the edentulous individual in a personal way, i.e., dating or living as neighbor. Men and women agreed on perceptions of social traits and dentition condition. These results suggest the presence of strong Western cultural values, whereby those who are missing teeth may experience significant barriers to personal and social success. 相似文献

The constant-RPE tracking model monitors progress over the course of exercise training. During aerobic exercise, prior work using this model has demonstrated similar relative intensities pre- and posttraining, while the absolute workload increases posttraining. However, the prediction equation associated with these changes has not been examined during resistance training. 22 men and 27 women (M age 64 yr.) participated in a 12-wk. resistance training. Orientation determined resistances associated with RPEs of 4, 5-6, 7-8, and 9 on the OMNI-Resistance Exercise Scale for each of seven exercises for each participant. Individuals trained 3 days a week for 12 wk. Linear regression was used to calculate percent of 1-repetition maximum (%1-RM) at RPE 4, 6, and 8 for the exercises. Paired sample t tests, comparing pre- and posttraining %1-RMs at each RPE, indicated that posttraining %1-RMs were higher for RPE 4 and 6 for each exercise, while at RPE 8, results were significant for only 3 exercises. Thus for at least the RPE 4 and 6, the constant RPE tracking model is appropriate for resistance exercise; however, the equation of prediction appears to differ from that for aerobic exercise. Development of a new prediction equation may be necessary to track relative strength in older adults. 相似文献

David Lewis has long defended an analysis of counterfactuals in terms of comparative similarity of possible worlds. The purpose
of this paper is to reevaluate Lewis’s response to one of the oldest and most familiar objections to this proposal, the future similarity objection. 相似文献

Members of the public (Study 1; n = 184) and university students (Study 2; n = 101) evaluated a piece of research and indicated their support for its continuation. The research findings were held constant, but the methods that revealed those findings were attributed to either neuroscience or social science, and the conclusions based on those findings were biased either in favor of men or in favor of women. Study 1 revealed that participants were more positive about research that affirmed their gender identity and that was based on neuroscience rather than social science. Study 2 found this pattern to be apparent in more specialist samples. Indeed, participants with some scientific training were more influenced by research that affirmed the reader's gender identity. Participants with less scientific training, in comparison, were more influenced by the type of science described when making judgments about the value of the research. Contrary to popular claims, this suggests that scientific knowledge alone is no protection against the effects of bias on research evaluation. Implications for the practice and popularization of science are discussed. 相似文献

Testing a self-determination theory intervention for motivating tobacco cessation: supporting autonomy and competence in a clinical trial. 总被引:1,自引:0,他引:1

A longitudinal randomized trial tested the self-determination theory (SDT) intervention and process model of health behavior change for tobacco cessation (N = 1006). Adult smokers were recruited for a study of smokers' health and were assigned to intensive treatment or community care. Participants were relatively poor and undereducated. Intervention patients perceived greater autonomy support and reported greater autonomous and competence motivations than did control patients. They also reported greater medication use and significantly greater abstinence. Structural equation modeling analyses confirmed the SDT process model in which perceived autonomy support led to increases in autonomous and competence motivations, which in turn led to greater cessation. The causal role of autonomy support in the internalization of autonomous motivation, perceived competence, and smoking cessation was supported. 相似文献
