Assessing the cumulative effects of stress: The association between job stress and allostatic load in a large sample of Chinese employees

Job stress can lead to various system dysfunctions, but until now no reliable biomarkers for its assessment have been identified. Allostatic load (AL) is an index that enables the cumulative effect on the body of chronic stress to be assessed, and is derived from a set of relevant biological measures. In this study, a 13-parameter index (building on the original 10-item index) was used to examine the relationship between job strain and AL. Participants were 1219 healthy Chinese employees. Job strain was measured using the Job Content Questionnaire, and AL was assessed by various possible stress responses, including blood pressure, cholesterol, indicators of glucose metabolism, and hormone and inflammation markers. AL in the high job strain group differed sharply from that in the low job strain group. The AL score was positively associated with age and educational level. Several individual parameters also differed between the two groups. Men scored significantly higher on AL and cardiovascular and metabolic health outcomes, whereas for women the associations appeared in the biological indicators. Analyses indicated that decision latitude (DL) and job demands were significantly related to AL. Job demands correlated significantly with the primary biological indicators and DL with the secondary health outcomes. In conclusion, this study provides evidence of the value of measuring allostatic load in assessing the chronic effects of job stress.     

Measuring the complexity of generalized linear hierarchical models

Measuring a statistical model's complexity is important for model criticism and comparison. However, it is unclear how to do this for hierarchical models due to uncertainty about how to count the random effects. The authors develop a complexity measure for generalized linear hierarchical models based on linear model theory. They demonstrate the new measure for binomial and Poisson observables modeled using various hierarchical structures, including a longitudinal model and an areal‐data model having both spatial clustering and pure heterogeneity random effects. They compare their new measure to a Bayesian index of model complexity, the effective number p_D of parameters (Spiegelhalter, Best, Carlin & van der Linde 2002); the comparisons are made in the binomial and Poisson cases via simulation and two real data examples. The two measures are usually close, but differ markedly in some instances where p_D is arguably inappropriate. Finally, the authors show how the new measure can be used to approach the difficult task of specifying prior distributions for variance components, and in the process cast further doubt on the commonly‐used vague inverse gamma prior.     

专业技术职务任职资格定量评审探讨

本文对如何搞好任职资格的评审提出了“申请评职基本分+专家组意识评审分”综合评审的模式设想,该设想强调目前资格的评审应以对国家作出的贡献为主,并以此强调,高级技术职务的任职要求应建立一个在全国范围内统一的最基本的个人“申请评职基本分”标准。本文对一些标准定分提出了初步设想,最后着重阐述了实行“申请评职基本分”的意义所在。     

论高等学校公共关系的开放式战略

大学毕业生社会择业的瓶颈问题,使高等学校公共关系处于比较危机的状态,协调好高等学校人才培养和社会人才市场需求之间的同步一体关系,是高等学校公共关系管理的当务之急。做好公共关系管理工作,首先要认清高等学校公共关系的本质,认清人才综合素质的培养达到社会需求标准的重要性;其次是要紧紧抓住高等学校公共关系的主体方面。由于高等学校三大职能相互关系所决定,人才培养是高等学校公共关系的主体方面。高等学校培养出的人才,要得到人才使用单位的认同与支持,高等学校必须在公共关系的管理上实施开放式战略,充分发挥社会行业专家的桥梁纽带作用,敞开校门办学,与社会需要同步运行,这样,大学毕业生社会择业的瓶颈问题就有希望得到解决。     

工作倦怠的结构与测量

各种职业的从业人员中普遍存在工作倦怠现象,工作倦怠会对个体的身心健康和工作产生消极影响,因此必须对个体的工作倦怠程度进行测量,继而进行干预。本文介绍了国外主要的工作倦怠结构理论,以及MBI、BM、OLBI和S—MBM量表,总结了每种量表的优缺点,指出了各种倦怠量表均存在的主要问题,提出了量表的开发和改进方向。     

工作特性与工作倦怠的关系研究

从工作激励潜能、工作特性及其与个体变量的交互作用的角度来分析工作倦怠,结果表明:激励潜能对工作怠慢有着预测作用,从工作本身中所获得的激励潜能越大,则工作怠慢程度越低,并且与性别、工作年限、婚姻存在着交互作用;此外,性别变量与工作完整性有着交互作用。为此,应该设计丰富化、扩大化及多元化的工作特性以提升工作的激励性,同时建立适当的倦怠管理机制,并考虑个体间的不同需求。
