This research is concerned with two topics in assessing model fit for categorical data analysis. The first topic involves the application of a limited-information overall test, introduced in the item response theory literature, to structural equation modeling (SEM) of categorical outcome variables. Most popular SEM test statistics assess how well the model reproduces estimated polychoric correlations. In contrast, limited-information test statistics assess how well the underlying categorical data are reproduced. Here, the recently introduced C2 statistic of Cai and Monroe (2014) is applied. The second topic concerns how the root mean square error of approximation (RMSEA) fit index can be affected by the number of categories in the outcome variable. This relationship creates challenges for interpreting RMSEA. While the two topics initially appear unrelated, they may conveniently be studied in tandem since RMSEA is based on an overall test statistic, such as C2. The results are illustrated with an empirical application to data from a large-scale educational survey. 相似文献

道教思想文化蕴涵着深刻的旅游本真性思想。道教"游"的概念,指谓生命的本真存在状态和方式,与现代旅游学追寻的旅游本真性要旨相契合。而道教中的"味道"之游,则充分展现和表达了本真性旅游体验的方法和过程。与此同时,道教"归于朴"的理念,更深刻阐明了旅游的本真价值目的性及人格境界提升功能。全面认识和把握道教的旅游本真性思想,对于当代中国旅游文化建设具有重要的理论和实践价值。 相似文献

采用中国汉字谜,通过模拟wallas(1926)关于顿悟问题解决的四个阶段,探讨了酝酿期有效提示和无效提示对猜字谜的影响。结果发现:有效提示组被试比无效提示组猜对了更多的靶字谜,反应时也更短;在脑电水平上,酝酿期的有效提示谜比无效提示谜在左前额叶分别于300ms-400ms,400ms-600ms,600ms-800ms内引发了更大的P300-400成分、P400-600成分、P600-800成分。表明有效提示谜比无效提示谜对靶字谜问题的解决有更大促进作用。 相似文献

Employees' innovative work behavior (IWB) is one of the key factors in improving organizational competitiveness. Previous studies show that challenge and hindrance stress can impact employees' IWB, but our understanding of the exact mechanism underlying the impact is still limited. The present study employed four scales (Challenge and Hindrance Stress Scale, Thriving at Work Scale, Chinese Emotional Exhaustion Scale, and Employee Innovative Behavior Scale) to collect questionnaire data from 789 employees in diverse organizations via an online platform. A two-path mediation model was constructed. The results show that: (a) challenge stress positively predicted thriving at work and IWB; (b) thriving at work played a partial mediation effect between challenge stress and IWB; (c) hindrance stress negatively predicted thriving at work and positively predicted emotional exhaustion; and (4) hindrance stress did not directly impact IWB while thriving at work and emotional exhaustion were main mediators in the relationship between hindrance stress and IWB. These findings suggest that employees should sensibly cope with different work stresses, while managers should plan work tasks scientifically and give employees adequate opportunities to learn and rest in order to keep them in a positive state to solve problems and work creatively. 相似文献

Based on career construction theory and the model of proactive motivation, the current research examined the mediating and moderating models for the relations among future work self, career adaptability, job search self-efficacy and employment status. A survey study was conducted among Chinese university graduates (N = 270). The results showed that future work self (measured at wave 1) had positive effect on employment status (measured at wave 3), with this relationship partially mediated by career adaptability (measured at wave 1) and job search self-efficacy (measured at wave 2). In addition, the results further revealed that the positive effect of future work self on job search self-efficacy was stronger among the graduates who had a higher level of career adaptability. In support of the hypothesized moderated mediation model, for individuals with a higher level of career adaptability, the indirect effect of future work self on employment status through job search self-efficacy was stronger. These findings carry implications for research on job search behavior, career education and career counseling. 相似文献
