Encouraging employees to co-operate: the effects of sponsored training and promotion practices on employees' willingness to work overtime

The ‘mutual-investment’ model argues that when employers invest more in the social exchange relationship between them and their employees, their employees will show more effort. In this paper we relate the ‘mutual-investment’ model to training and promotion (possibilities) and examine if these kinds of career-enhancing measures influence the willingness of employees within organizations to work overtime. To test this hypothesis, a vignette experiment was conducted in five organizations (N = 388; 1,531 vignettes). Multilevel analyses show that employees are more willing to work overtime when their employer has provided for training, when the employee recently was promoted, when the supervisor was supportive in the past and when co-workers approve of working overtime and behave similarly. But we did not find that future promotion chances affect willingness to work overtime.     

南宁市周末城郊旅游发展对策研究

由于城市化进程不断推进,南宁市人口规模稳步扩大,以及市民生活水平不断提高及我国节假日制度的改革,周末城郊旅游将越来越受到市民的青睐。因此,南宁市周末城郊旅游发展前景美好,值得我们重视。通过问卷调查的形式,调查了南宁市周末城郊旅游“行、住、食、游、购、娱”的供求情况和城郊旅游景区的知名度,收集到相关数据,据此运用定量分析法进行分析,发现南宁市周末城郊旅游供给与需求并不均衡,存在着许多问题。文章从供求角度对南宁市周末城郊旅游进行调查、分析,总结现存问题,并在此基础上研究其发展对策。     

MTO生产模式的交货期决策研究

基于订单式生产(MTO)模式下的中小企业的生产运营环境,对产品提前交货、延期交货及加班赶工或外协所引发的成本进行分析,构建了交货期决策模型,分析了模型的最优解。实例计算结果证明了该模型的有效性,该模型可以为订单式生产企业交货期决策提供有益的参考。

Asymmetric information about workers' productivity as a cause for inefficient long working hours

In this paper, a model of labor contracting with asymmetric information is developed in order to explain the existence of inefficient long working hours. Since firms cannot observe workers' true productivity, they use long working hours as a mechanism to sort productive workers. The model therefore predicts that workers with a high productivity will tend to work inefficient long hours. An empirical analysis confirms this prediction: high-productivity workers are more likely to experience hours constraints in the form of overemployment than low-productivity workers. Moreover, the extent of overemployment is positively related to productivity.     

基于时间测定法的工时定额标准化研究

工时定额是企业生产经营需要的一项基础性数据,一套科学合理的工时定额对企业合理安排生产、公平按劳分配、缩短生产(维修)周期等都有着至关重要的作用。在规范工时测定程序的基础上,就如何利用时间测定法对工时定额进行标准化进行了研究,得到了一套从工时测定开始至获得标准工时的科学方法与程序,以及标准工时的量化公式。     

从打瞌睡探析日本文化

打瞌睡,在世界各个国家都有,但是像日本人那样无论在拥挤的电车里还是在重要的国际会议上打瞌睡的国家并不多见。大家都知道日本是个勤劳甚至过劳的民族,但是打瞌睡的这些人都是勤劳的吗?他们为什么爱打瞌睡呢?又是什么夺走了他们的睡眠呢?本文主要从打瞌睡这一现象来分析其中隐藏的日本社会文化。     

基于6 Sigma方法的设计成本管理体系优化——非标设备制造企业

虽然设计成本在产品成本体系中所造成的重大影响度已经成为了众多成本研究者的一个共识,但是对设计成本的研究却停留在一个比较浅显的阶段,从理论和技术上都不太成熟。本文通过6 Sigma方法对一个非标设备制造企业的设计成本体系进行研究,找出设计成本的主要影响因素并对其改善,完善设计成本体系,以达到对该公司产品成本改善的目的。     

Individual versus institutional investors and the weekend effect

Since the late 1980’s, considerable research has focused on the behavior of individual versus institutional investors and the potential patterns which may emerge from their trading activities. Miller (1988) and Abraham and Ikenberry (1994) posit that the tendency for negative Monday returns on equity (i.e., the weekend effect) is at least partially explained by the trading behavior of individual investors. Sias and Starks (1995), on the other hand, present empirical evidence showing a dominant role played by institutional traders. This study contributes to the literature by distinguishing between individual versus institutional trading as it relates to the weekend effect. We find that the information-processing hypothesis is consistent with observed institutional trading patterns, thus supporting the results of Sias and Starks (1995). In addition, these results are shown to be robust with respect to market type (i.e., auction and dealer markets).     

缺陷披露、审计意见与内部控制质量提升

基于理性预期和管理者风险偏好视角,对缺陷披露、非标意见和内部控制质量提升之间的关系从理论上进行分析,在此基础上选取A股上市公司2009—2014年相关数据进行实证研究,研究结果表明：企业的财务报告在当年被出具非标意见后,下年度该企业的内部控制质量会有显著提升,内控缺陷披露会显著增强非标意见对控制质量提升的正面影响。在对当年被出具非标意见的企业样本进一步分组进行回归分析后发现：相对于披露了控制缺陷的企业而言,未披露控制缺陷的企业下年度控制质量没有显著提升。     

基于人工神经网络的非标产品制造成本估算研究

大型和形状复杂的非标产品的生产成本,是很难估算的。目前采用的人工方法估算的误差较大。当成本估算用于招标目的时,这样的误差将产生不利的后果。成本高估承担的风险,是使公司缺乏竞争力,失去客户,而低估了成本,赢得了合同,但招致财务的损失。因此,一个精确的产品生产成本估算方法,对项目管理而言至关重要。本文应用神经网络建立的参数模型,针对大型和形状复杂的非标产品的生产成本估算和目前采用的手动估算相比,精确度有了很大提高。     

Local Times of Bernoulli Walk

The joint probability generating functions of local times of Bernoulli walk at various stopping times are determined by simple functional equations. The results can be interpreted by means of branching processes with immigration satisfying the same equations. One way of working with these results is to specialize and evaluate the derived equations, but a more elegant and efficient way is to compare these equations with corresponding functional equations for branching processes.
