We used mindfulness as a mediating variable and self-efficacy as a moderator to examine the relationship between academic procrastination and subjective well-being. Participants comprised 512 college students from Hangzhou, Xiamen, and Huizhou in China. Results show that academic procrastination
had a negative impact on subjective well-being, and that mindfulness was a mediator in this relationship. In addition, self-efficacy played a moderating role in the academic procrastination–mindfulness relationship, and, to a certain extent, regulated the relationship between academic
procrastination and subjective well-being. Thus, the stronger the self-efficacy of college students, the weaker was the negative predictive effect of academic procrastination on mindfulness. The significance of mindfulness and self-efficacy regarding subjective well-being among procrastinators
is discussed.

We explored the mediating role of perceived organizational support (POS) on the relationship between job security and 2 dimensions important in employee work outcomes: extrarole behavior and turnover intention. Participants were 212 subordinate team members and their supervisors, who
were employed by an air transportation group in China, and we found that POS partially mediated the relationship between job security and extrarole behavior and fully mediated the relationship between job security and turnover intention. Implications for management practice and limitations
in this study are discussed.

Abstract Background Comprehensive smoke-free legislation has been implemented in many countries. The current study quantitatively examined the reduction in risk of acute myocardial infarction (MI) occurrence following the legislations and the relationship with the corresponding smoking prevalence decrease. Methods PubMed, EMBASE, and Google Scholar databases and bibliographies of relevant studies and reviews were searched for potential original studies published from January 1, 2004, through October 31, 2011. Meta-analysis was performed using a random effect model to estimate the overall effects of the smoking-free legislations. Meta-regression was used to investigate possible causes of heterogeneity in risk estimates. Results A total of 18 eligible studies with 44 estimates of effect size were used in this study. Meta-analysis produced a pooled estimate of the relative risk of 0.87 (95% confidence interval (CI): 0.84 to 0.91). There was significant heterogeneity in the risk estimates (overall I 2 = 96.03%, p<0.001). In meta-regression analysis, studies with greater smoking prevalence decrease produced larger relative risk (adjusted coefficient −0.027, 95% CI: -0.049 to −0.006, p=0.014). Conclusion Smoke-free legislations in public and work places were associated with significant reduction in acute MI risk, which might be partly attributable to reduced smoking prevalence.
