The current study assessed the measurement equivalence of the Wong & Law Emotional Intelligence Scale (WLEIS) with three groups of Chinese university students. Two research sessions were conducted-one in Beijing, China with university students (N = 680), and the other in Calgary, Canada where two groups of Chinese students were administered the WLEIS in either Chinese (N = 151) or English (N = 151). The WLEIS had satisfactory reliability, the four-factor structure was replicated, and metric invariance was supported across the three groups. The present study provided empirical support to the growing emotional intelligence measurement invariance literature and demonstrated the robustness of both the English and Chinese versions of the WLEIS.

Under the framework of the viscous chromohydrodynamics, the gluon self-energy is derived for the quark-gluon plasma with shear viscosity. The viscous electric permittivity and magnetic permeability are evaluated from the gluon self-energy, through which the refraction index is investigated. The numerical analysis indicates that the refractive index becomes negative in some frequency range. The start point for that frequency range is around the electric permittivity pole, and the magnetic permeability pole determines the end point. As the increase of η/s, the frequency range for the negative refraction becomes wider.

Abstract. Neuroticism overlaps substantially with several perfectionism dimensions, depression, anxiety, stress, and life satisfaction. Accordingly, research testing whether perfectionism dimensions explain unique variance in these outcomes beyond neuroticism is needed. Research on cultural differences in perfectionism is also scarce. And it is especially unclear whether the link between perfectionism and psychological distress differs across individualistic and collectivistic cultures. Our study addressed these important gaps in knowledge. A sample of undergraduates from a traditionally individualistic culture (Canada; N = 449) and a traditionally collectivistic culture (China; N = 585) completed measures of self-oriented perfectionism, personal standards, socially prescribed perfectionism, concern over mistakes, doubts about actions, depression, anxiety, stress, and satisfaction with life. To test the incremental validity of perfectionism dimensions beyond neuroticism, as well as to test potential moderating effects of culture, four hierarchical regression analyses with interactions were conducted. Results supported the explanatory power of concern over mistakes and doubts about actions, beyond neuroticism and culture, in the prediction of depression, anxiety, and stress. As the first study to explore the incremental validity of perfectionism dimensions across undergraduates from traditionally individualistic and collectivistic cultures, our research both extends and clarifies understanding of the predictive power of perfectionism in important ways.
