Emotional labor and family quality: the role of work-family positive spillover

There is increasing research interest in both types of emotional labor at work (i.e. surface acting and deep acting), but the effects of emotional labor at work on employees’ emotional labor at home and their family members’ family quality have not yet been explored. Drawing on work-family enrichment theory, this study investigated the mechanism underlying the relationship between employees’ emotional labor at work and their spouses’ perceived family quality by focusing on the mediating role of employees’ emotional labor at home and the moderating role of work-to-family positive spillover (WFPS). The results from a time-lagged three-wave survey of 193 Chinese employee-spouse dyads indicated that surface acting at home mediated the relationship between surface acting at work and spousal ratings of family quality. Although deep acting at work was positively related to deep acting at home, deep acting at home was not significantly related to family quality. WFPS strengthened the relationship between surface acting at work and surface acting at home. This study extends emotional labor theories to the family domain and provides insights into the mediating mechanisms and boundary condition through which emotional labor at work relates to spouses’ perceptions of family quality. The implications for theory and management practice are discussed.

2009年广水市高中生乙肝表面抗原检测结果分析

目的了解2009年广水市高中生乙肝病毒(HBV)感染情况,为制定乙肝防治对策,保护学生身体健康提供科学依据。方法 HBsAg采用酶联免疫吸附法(ELISA)对广水市所辖区域内七所高中生共计8486名进行检测,并对检测结果进行统计分析。结果检出HBsAg阳性者共671例,阳性率7.91%。其中男生HBsAg阳性427例,阳性率5.03%;女生HBsAg阳性244例,阳性率为2.88%;二者差异有统计学意义。结论男生HBV感染率显著高于女生,可能与男生没有女生讲究卫生,生活用品交叉使用,尤其与交叉使用牙刷和剃须刀有关。为有效降低高中生HBV感染率,可加大对高中生健康教育宣传力度、对高中学生定期进行健康体检、并对HBsAg阴性者进行乙肝疫苗的接种工作,提高免疫覆盖率和人群免疫水平。

To sigmoid-based functional description of the volatility smile

We propose a new static parameterization of the implied volatility surface which is constructed by using polynomials of sigmoid functions combined with some other terms. This parameterization is flexible enough to fit market implied volatilities which demonstrate smile or skew. An arbitrage-free calibration algorithm is considered that constructs the implied volatility surface as a grid in the strike-expiration space and guarantees a lack of arbitrage at every node of this grid. We also demonstrate how to construct an arbitrage-free interpolation and extrapolation in time, as well as build a local volatility and implied pdf surfaces. Asymptotic behavior of this parameterization is discussed, as well as results on stability of the calibrated parameters are presented. Numerical examples show robustness of the proposed approach in building all these surfaces as well as demonstrate a better quality of the fit as compared with some known models.
