Drawing on Dewey's pragmatic perspective on talent cultivation and previous research on promoting employee creativity in industry, this study investigates student creativity performance in relation to teacher's encouragement, intrinsic motivation, and creative process engagement. Based on survey data collected from 140 vocational high school students who participated in a nation‐wide contest in Taiwan, path analyses were performed using structure equation modeling techniques. The results indicate that both teacher's encouragement and intrinsic motivation have a significant, although indirect, effect on student creativity, and that creative process engagement, as opposed to teacher encouragement or intrinsic motivation, has a direct and significant mediating effect on student creativity. This finding is in partial agreement with prior research which reports student creativity is positively associated with teacher encouragement and intrinsic motivation, highlighting the mediating role of creative process engagement in facilitating student creative performance.  相似文献

The purpose of this study was to test the relationship between self-efficacy, readiness to change, and Alcohol Use Disorders Identification Test (AUDIT) risk levels in a sample of active duty drinkers who were seeking care in a military emergency department. Civilian health educators screened participants for alcohol use with the AUDIT and collected sociodemographic, service, and drinking-related cognitions data from active duty patients admitted to an emergency department. A total of 787 active duty military personnel participated in the study. Almost half (48%) drank at least once a week and 32% reported consuming five or more alcoholic drinks during a typical drinking episode. One in five participants reported heavy episodic drinking weekly to almost daily. Results of a multinomial logistic regression model showed that active duty service members with a self-reported diagnosis of posttraumatic stress disorder since joining the military were more likely to be an at-risk or high/severe risk drinker relative to a low risk drinker. Higher controlled drinking self-efficacy was associated with a decrease in the odds of being either an at-risk or high/severe risk drinker. Increased readiness to reduce drinking was associated with an increase in the odds of being either an at risk or high/severe risk drinker. The results of this research suggest self-efficacy to control one’s heavy drinking as well as readiness to change may be important factors to consider when designing alcohol education programs within the military.  相似文献

This study assesses the retractions of scientific articles in engineering journals indexed on the Web of Science from 1945 to 2015. The data set was built based on documents containing the keywords retracted, retraction, withdrawal, or redress. We used database exploration techniques, including Structured Query Language and analysis of variance, for data analysis. We analyzed 238 retractions published by 117 journals. The most common reason for retraction was unethical research, and higher impact factors journals tended to publish more retractions. In conclusion, most of the analyzed retractions were the result of unethical research and were retracted by editors.  相似文献

This study investigated moderators of newlywed spouses' accuracy in judging each other's personality. Spouses in 154 predominantly Hispanic newlywed couples rated their own and their partners' personality traits. Full‐sample results showed significant associations between perceivers' and targets' personality ratings (“truth force”/“tracking accuracy”). Positive directional bias (perceivers' mean trait ratings of targets exceeding targets' self‐ratings) also was evident. Positive directional bias occurred when perceivers had little familiarity with their spouse prior to dating and when perceivers had high self‐esteem. Truth force/tracking accuracy increased with less time spent cohabiting and higher perceiver self‐esteem. Positive associations between perceivers' self‐esteem and ratings of partners on positively valenced traits were reduced when partners had had greater opportunities to observe one another's behaviors.  相似文献
