心理契约视角下的高校学风建设策略探析

心理契约现象存在于诸多管理活动中,将心理契约引入高校学风建设领域具有可行性.通过对心理契约在高校学风建设中的适用性分析后,就心理契约对学风建设产生影响的机制问题,将心理契约与学风建设的关系分为建立、调适、实现3个阶段进行分析.在此基础上,建议从明确学校和学生的心理期望、强化沟通机制、积极履行心理契约等角度建立高校学风建设心理契约机制,推进高校学风建设.     

The labour division of Italian couples after a birth: assessing the effect of unobserved heterogeneity

The results of previous studies on the effect of childbearing on both parents’ paid and unpaid work suffer from the difficulty related to the specification of latent variables that influence the relationship between reproductive behaviour of the couple and working activity. The aim of this study is to estimate the effect of transition to parenthood on the partners’ division of labour by accounting for latent variables, such as the bargaining process between partners and endogenous fertility decisions. In particular, this is the first time that our specific estimation strategy has been applied to determine the impact of childbearing on the division of household labour between partners taking into account the reverse causality effect between labour and fertility decisions. We use longitudinal data on married or cohabiting Italian couples provided by the Italian panel survey of the Generation and Gender Program. Our results are consistent with previous studies, and show that the birth of a child affects a woman’s unpaid labour strongly and positively and her paid labour negatively, while men’s work is mostly unaffected. Moreover, when partners hold traditional attitudes regarding gender roles and the family, the female partner is even more strongly affected by childbearing in terms of total amount of labour (paid plus unpaid). However, our sensitivity analysis shows that these results appear only when our correction strategy for the misspecification of latent variables is applied.

高管领导力与组织双元能力关系述评及展望:基于国有企业改革背景

在当前国有企业改革的背景下,以往从所有权结构和领导特质之间关系来探讨高管层角色定位问题的研究,已经不能完全适应建立健全现代化公司治理结构的需要.基于组织双元能力理论,文章对高管领导力和组织双无能力之间的关系进行述评,认为在国有企业改革背景下,高管行为整合更能促进组织双元能力的实现.在此基础上,从三方面分析未来研究方向:基于国有企业改革背景,对高管行为整合维度重新探讨和定义、分析可行的高管行为整合前置影响因素以及高管行为整合与组织双元能力关系的调节变量.文章力图开创国有企业研究的新视角,为国有企业改革和公司内部运作规范提供借鉴.     

Continuous event monitoring via a Bayesian predictive approach

In clinical trials, continuous monitoring of event incidence rate plays a critical role in making timely decisions affecting trial outcome. For example, continuous monitoring of adverse events protects the safety of trial participants, while continuous monitoring of efficacy events helps identify early signals of efficacy or futility. Because the endpoint of interest is often the event incidence associated with a given length of treatment duration (e.g., incidence proportion of an adverse event with 2 years of dosing), assessing the event proportion before reaching the intended treatment duration becomes challenging, especially when the event onset profile evolves over time with accumulated exposure. In particular, in the earlier part of the study, ignoring censored subjects may result in significant bias in estimating the cumulative event incidence rate. Such a problem is addressed using a predictive approach in the Bayesian framework. In the proposed approach, experts' prior knowledge about both the frequency and timing of the event occurrence is combined with observed data. More specifically, during any interim look, each event‐free subject will be counted with a probability that is derived using prior knowledge. The proposed approach is particularly useful in early stage studies for signal detection based on limited information. But it can also be used as a tool for safety monitoring (e.g., data monitoring committee) during later stage trials. Application of the approach is illustrated using a case study where the incidence rate of an adverse event is continuously monitored during an Alzheimer's disease clinical trial. The performance of the proposed approach is also assessed and compared with other Bayesian and frequentist methods via simulation. Copyright © 2015 John Wiley & Sons, Ltd.     

震后人群常见的心理困扰及应对策略

创伤后应激障碍又称延迟性心因性反应,是灾难性事件发生后在灾区及灾区之外的人们中普遍存在的一种心理应激反应.它不仅有滞后性,持续时间长,而且可能伴随当事人终生,必须引起社会的广泛重视.而要消除心理"余震",除介入及时外,必须做好打持久战的心理准备.对汶川大地震也是如此.为此,必须充分发挥传媒的社会稳定功能,确保信息准确,为灾区群众提供心理屏障;还要建立社会支持系统.帮助丧失亲朋者顺利度过悲哀历程,学会面对事实,寻求新的生活目标.此外,探索震后心理调适方法,鼓励震后人群进行自我情绪调整也十分必要.
