工作满意度、组织承诺与关系绩效的关系实证研究

通过在成都、广州、深圳一些企业的实证研究,探讨组织承诺、工作满意度与关系绩效之间的关系,发现组织承诺三维度、工作满意度五维度与关系绩效两维度之间几乎都具有非常显著的相关关系;但是将工作满意度和组织承诺作为关系绩效的预测变量时,发现二者的因果关系非常不显著,因此推测工作满意度、组织承诺可能是关系绩效的前因中介变量或者调节变量。     

An Interpretation of A Rose for Emily From a Feminist Perspective

Feminist Criticism,for women, is described as an self-awakening, and self-improvement.It is the voice of Feminism.By taking it,feminism breaks through the patriarchy-centered so-cialism.This paper analyses the story A Rose for Emily from a feminist perspective,explores the social roots that lead to the tragedy of Emily, and points out that Emily is victimized by the male-centered society and the southern conventional moral standards.

Effects of a kindergarten-based,family-involved intervention on motor performance ability in 3- to 6-year-old children: the ToyBox-study

This study targeted to examine the effect of the ToyBox-intervention, a kindergarten-based, family-involved intervention, aiming to improve preschooler’s energy-related behaviours (e.g., physical activity) on motor performance ability. Physical activity sessions, classroom activities, environmental changes and tools for parents were the components of the 1-year intervention. The intervention and control were cluster-randomised, and children’s anthropometry and two motor test items (jumping from side to side, JSS and standing long jump, SLJ) were assessed. A total of 1293 (4.6 ± 0.69 years; 52% boys) from 45 kindergartens in Germany were included (intervention, n = 863; control, n = 430). The effect was assessed using generalised estimating equation. The intervention group showed a better improvement in JSS (Estimate 2.19 jumps, P = 0.01) and tended to improve better in SLJ (Estimate 2.73 cm, P = 0.08). The intervention was more effective in boys with respect to SLJ (P of interaction effect = 0.01). Children aged <4.5 years did not show a significant benefit while older children improved (JSS, Estimate 3.38 jumps, P = 0.004; SLJ, Estimate 4.18 cm, P = 0.04). Children with low socio-economic status improved in JSS (Estimate 5.98 jumps, P = 0.0001). The ToyBox-intervention offers an effective strategy to improve specific components of motor performance ability in early childhood. Future programmes should consider additional strategies specifically targeting girls and younger aged children.

Effects of false-start disqualification rules on response-times of elite-standard sprinters

The 100 ms ruling for false start disqualification at athletic competitions governed by the International Association of Athletics Federations has been in force since the early 1990s. Throughout this period, there have been marked changes to the rules that govern the disqualification of athletes from sprint events incorporating starts from blocks. This study analysed all available World and European Championship response-time (RT) data from 1999 to 2014 to examine effects of rule changes on competition RT at major championships. The exponentially modified Gaussian distribution was used to model RT and make comparisons relative to athletes’ sex, ruling periods and competition rounds. Revised RT thresholds of 115 ms and 119 ms were identified for men and women, respectively, indicating that the current 100 ms rule could result in some false starts not being detected in competitive athletics. The study proposes that when using existing International Association of Athletics Federations approved systems, the false start detection threshold should be increased and that men and women athletes should have different thresholds because of substantial evidence of a sex-based difference in RT in elite-standard athletes.
