Highlights Mobile phone addiction was significantly and positively associated with psychological distress. Rumination mediated the association between mobile phone addiction and psychological distress. The direct effect of mobile phone addiction on psychological distress could be moderated by the capacity to be alone. The capacity to be alone could also act as a buffer in the indirect effect of mobile phone addiction on psychological distress via rumination. Both the direct effect and indirect effect of mobile phone addiction on psychological distress were stronger for adolescents with lower level of capacity to be alone.

Extant research suggests that workplace ostracism has a detrimental impact on the outcomes of employees. However, very little is known about the impact of workplace ostracism on sleep quality. Therefore, this study aimed to address this gap in the literature. By employing the extended stressor-detachment model, we investigated the mediating role of psychological detachment and the moderating role of coping humor. We used a self-report questionnaire and a time-lagged research design to assess employees’ workplace ostracism, coping humor, psychological detachment, and sleep quality. A total of 403 valid questionnaires were obtained from participants in full-time employment in China. As predicted, the results showed that workplace ostracism is negatively associated with psychological detachment, which in turn, impairs sleep quality. We further found that high levels of coping humor buffer the negative effect of workplace ostracism on psychological detachment and sleep quality. In addition, the moderation effect of coping humor on the relationship between workplace ostracism and sleep quality is mediated by psychological detachment. Finally, based upon the results, we discuss the theoretical implications, provide practical proposals for managers and policymakers, and make suggestions for the direction of further research.

Relativistic heavy-ion collisions can produce extremely strong magnetic field in the collision regions. The spatial variation features of the magnetic fields are analyzed in detail for non-central Pb -Pb collisions at LHC √ sNN = 900, 2760 and 7000 GeV and Au-Au collisions at RHIC √ sNN = 62.4, 130 and 200 GeV. The dependencies of magnetic field on proper time, collision energies and impact parameters are investigated in this paper. It is shown that a enormous with highly inhomogeneous spatial distribution magnetic field can indeed be created in off-central relativistic heavy-ion collisions in RHIC and LHC energy regions. The enormous magnetic field is produced just after the collision, and the magnitude of magnetic field of LHC energy region is larger that of RHIC energy region at the small proper time. It is found that the magnetic field in the LHC energy region decreases more quickly with the increase of the proper time than that of RHIC energy region.

The phenomenon of problematic mobile phone use (PMPU) has been incredibly increasing, especially in Asian countries. Prior studies have argued that negative emotion is linked to PMPU. Based on the cognitive‐behavioural model of pathological Internet use and the buffering model of social support, our purpose is to identify the nuanced mediators of the rumination subtypes (i.e., reflection and brooding) and examine the moderator of social support in the relation between negative emotion and PMPU. A sample of 1,014 college students was recruited to complete the scales of PMPU, depression, anxiety, rumination (i.e., reflection and brooding), and social support. Results showed that (a) reflection did not mediate a link between negative emotion and PMPU whereas brooding partially mediated the link, and (b) both the direct association between negative emotion and PMPU and the mediated effect of brooding were moderated by social support, and they were stronger when social support was low rather than high. The study distinguishes the mediated effect of rumination subtypes and incorporates social factor in the relationship between negative emotion and PMPU, which deepens our understanding of how and when negative emotion relates to PMPU.
