In this study, we developed and validated an instrument for measuring postgraduate competence and examined the relationships between postgraduate competence and academic research performance, along with the mediating role of psychological capital. Based on two independent samples, the results provided robust evidence of postgraduate competence composed of six dimensions. Adopting a two-wave survey at two different time periods, we conducted a questionnaire survey on 364 postgraduates from three top universities in China by random sampling. The results indicated that postgraduate competence was positively associated with academic research performance. Among the competences composed of six dimensions, research ability was the most predictive dimension of academic research performance. Additionally, psychological capital partially mediated the relationship between postgraduate competence and academic research performance. These findings contributed to the ongoing discussion about improving postgraduates’ academic research performance under the circumstance of competence-based education.
The popularity of social media, such as WeChat and Weibo in China, has provided an opportunity to develop social commerce. Although shopping through social commerce platforms is widely favored by consumers, the factors affecting consumers’ decision-making behavior in the social commerce environment remain unclear. Therefore, from the perspective of the stimulus–organism–response (SOR) theory, we construct a consumer repurchase decision model in the social commerce environment and analyze the influencing mechanism of social commerce features (interactivity, recommendations, and feedback) on perceived value (utilitarian value and hedonic value) and consumers’ repurchase intention. The empirical results found that social commerce features are positively related to the generation of perceived value, which in turn drives consumers to form repurchase intentions. We also found some mediating effects of perceived value. The study’s conclusions clarify the intrinsic influence mechanism of social commerce features on consumers’ perceived value and repurchase intentions. In addition, it can provide some theoretical guidance for future research and business.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
