股票流动性与期望收益的关系研究

本文选取换手率作为股票流动性指标,采用FM两阶段截面回归方法研究了股票流动性与期望收益的关系。研究表明,我国股票市场流动性的波动较为稳定;股票流动性和期望收益的异常波动主要受政策的影响,但在周内的变化不存在系统性差异;上市公司的市场价值与股票收益无关;股票的流动性与期望收益负相关;投资者可以根据股票流动性与期望收益的关系套利。     

入职期望与员工离职的关系——期望落差假设在中国情境下的验证

本研究在回顾期望落差假设分歧并分析其原因的基础上,以"新员工入职期望问卷"为测量工具,以我国某大型股份制企业2005年招聘的336名新员工为研究对象,采取纵向研究设计,在新员工进入企业半年内四次测量入职期望,并在第二年底收集员工主动离职信息,运用生存分析方法,研究两者关系。结果表明:(1)员工近期经历对主动离职有显著预测作用,入职期望及组织进入早期的经历对主动离职的预测作用不显著,没有支持期望落差假设;(2)团队期望在团队经历与主动离职的关系中起调节作用。由本研究引发的测量时间、竞争风险模型等问题值得进一步研究。     

Initiating structure leadership and employee behaviors: The role of perceived organizational support,affective commitment and leader–member exchange

The aim of this study was to examine the mediating role of perceived organizational support (POS) and affective organizational commitment (AOC) in the relationship between initiating structure (ISL) and employee behaviors. In addition, we also analyzed the moderator role of leader–member exchange in this relationship along three dimensions (affect, loyalty and professional respect). We conducted a survey-based study of 484 employees of a retail business and the results of the multiple regression analyses indicate that POS and AOC act as mediators in the relationship between ISL and two employee behaviors (extra-role organizational citizenship behaviors and turnover). Further, our results support the moderator effect of professional respect in the positive relationship between ISL and POS. This study makes an interesting contribution to the literature on ISL and its effects by construing POS as a consequence of this leadership style, and by adding professional respect among the possible moderators. Research avenues, limitations, and the practical implications of our findings are discussed.     

CEO health

Using comprehensive data on 28 cohorts in Sweden, we analyze CEO health and its determinants and outcomes. We find CEOs are in much better health than the population and on par with other high-skill professionals. These results apply in particular to mental health and to CEOs of larger companies. We explore three mechanisms that can account for CEOs’ robust health. First, we find health predicts appointment to a CEO position. Second, the CEO position has no discernible impact on the health of its holder. Third, poor health is associated with greater CEO turnover. Here, both contemporaneous health and health at the time of appointment matter. Poor CEO health also predicts poor firm outcomes. We find a statistically significant association between mental health and corporate performance for smaller-firm CEOs, for whom a one standard deviation deterioration in mental health translates into a performance reduction of 6% relative to the mean.     

Using Resilience to Reconceptualise Child Protection Workforce Capacity

Abstract

Current approaches to managing and supporting staff and addressing turnover in child protection predominantly rely on deficit-based models that focus on limitations, shortcomings, and psychopathology. This article explores an alternative approach, drawing on models of resilience, which is an emerging field linked to trauma and adversity. To date, the concept of resilience has seen limited application to staff and employment issues. In child protection, staff typically face a range of adverse and traumatic experiences that have flow-on implications, creating difficulties for staff recruitment and retention and reduced service quality. This article commences with discussion of the multifactorial influences of the troubled state of contemporary child protection systems on staffing problems. Links between these and difficulties with the predominant deficit models are then considered. The article concludes with a discussion of the relevance and utility of resilience models in developing alternative approaches to child protection staffing issues.     

国有控股、经营者变更和公司绩效

本文从国有控股上市公司董事长职业生涯考虑角度,研究董事长变更和绩效的关系。发现董事长免职和公司绩效恶化正相关,控股股东对董事长的考核以长期绩效和相对绩效(相对于前任董事长)为主,董事长任期和免职负相关,和控股股东的良好关系可以降低董事长被免职的概率。研究表明,国有控股上市公司经营者变更的激励模式与国际公众公司相近。     

统筹城乡建设用地中的农民土地权益保障——以浙江省宁波市为例

城镇建设用地增加与农村建设用地减少相挂钩是破解城市建设用地供给不足和农村建设用地闲置浪费双重矛盾的有效方式,也是优化土地资源配置的要求。在统筹城乡建设用地中,农民的土地权益容易受到侵害,需要通过提高集体建设用地指标交易费用、征地补偿费用以及征收集体建设用地流转累进税等方式建立土地收益分享机制,推动城乡统筹发展。     

职业成长与离职倾向:职业承诺与感知机会的调节作用

本文构建了职业成长对离职倾向的关系模型,实证分析了职业成长对离职倾向的作用机理。识别了职业成长与离职倾向关系中的两个重要调节变量,即职业承诺和感知机会。通过对九个城市961名企业员工的调查,采用回归分析处理数据,研究结果表明:职业成长对离职倾向具有很好的预测作用,职业成长四个因素对离职倾向均存在显著的影响;职业目标进展与职业能力发展交互作用于离职倾向;职业承诺越高的员工,他们对自身的职业能力发展、晋升速度越加关注,更可能会因为职业能力发展受限和晋升速度缓慢而产生高的离职倾向;随着员工感知机会的增加,职业成长对离职倾向的预测作用逐渐增强。     

个人-组织匹配在外资医药企业员工离职倾向决定中的调节效应研究

本文采用我国外资医药企业员工样本,运用层级回归方法对员工离职倾向的主要结构化变量和环境变量的解释能力进行了检验,在此基础上提出并检验了个人-组织匹配度对员工离职倾向的解释能力,进而验证了个人-组织匹配度在员工离职倾向决定过程中的调节效应.     

上市公司高管更替模式对企业绩效的影响

本文以上市公司2005-2009年间高管更替数据为研究样本,引入了高管团队重组和战略连续性作为中介变量,探讨了不同高管更替模式对企业绩效的影响路径。研究结果表明,上市公司高管强制更替外部聘任对高管团队重组有正向影响,对战略连续性有负向影响,对企业绩效有负向影响,其中高管团队重组和战略连续性在强制更替外部聘任与企业绩效之间起到中介效应;上市公司高管强制更替内部聘任对高管团队重组影响不显著,对战略连续性有正向影响,对企业绩效有正向影响,其中战略连续性在强制更替内部聘任与企业绩效之间起到中介效应;另外,高管团队重组对企业绩效有负向影响,战略连续性对企业绩效有正向影响。
