Stochastic comparisons for the number of working components of a system in random environment

In terms of stochastic orders, the purpose of this paper is to show how the random environment can affect the number of working components of a system with heterogeneous components sharing a common random environment. Applications to a class of semiparametric mixture models, stress-strength model and warm standby system are presented.     

How does growth need strength influence employee outcomes? The roles of hope,leadership, and cultural value

Abstract

Strong growth need is essential if an employee is to be motivated to complete complex and challenging jobs. It is important for organizations to attract employees with high growth need strength and help them achieve positive outcomes. However, limited research has been conducted to examine the mechanism underlying growth need strength’s positive effect on employee outcomes. Based on hope theory, we hypothesized that hope mediates the effect of growth need strength on job performance and affective commitment by transforming employees’ general desire for personal growth into goal-related cognitive thinking, comprising both ‘will’ and ‘ways’. We further hypothesized the moderating effect of transformational leadership, and the joint moderating effect of transformational leadership and individual power distance on the relationship between growth need strength and hope. We tested our hypotheses with data from a sample of 265 subordinate–supervisor dyads from China. Data analysis results supported the mediating role of hope. We found that growth need strength has a stronger effect on hope when transformational leadership is higher, and this effect is the strongest when both transformational leadership and individual power distance are simultaneously higher. The implications of these findings for human resource management research and practice are discussed.

市场经济中企业理论演化过程研究及其启示

市场经济逐渐取代封建经济的过程实际上是和企业演化过程结合在一起的,在这个过程中,不同的时期产生了不同的具有明显时代背景的企业理论。根据这些企业理论产生的先后顺序和时代背景,本论文先后研究了斯密的企业理论、马克思的企业理论和现代西方学者的企业理论,并在此基础上得出了对我国经济转型时期企业演化实践极有意义的启示。     

理性与良知：“大跃进”时期的县级官员

“大跃进”时期的县级官员在整个国家的行政结构中处于一个夹层位置，一方面其命运取决于上级的好恶，另一方面对下级和民众的权力基本不受到制约，因此他们从理性的角度发出，只能对上惟命是从，但是他们中的一些人，对民众所遭到的痛苦，表现出良知的一面。有一部分县级官员为上级的错误和自己的过失承受了惩处，不过最根本的原因是行政体制所造成的，在一定程度上说，县级官员也是行政体制问题的牺牲品。

Retrospect of the Chinese Exchange Rate Regime after Reform： Stylized Facts during the Period from 2005 to 2010

In the present paper, we estimate the de facto RMB exchange rate regime, the currency basket, the floating band and the foreign exchange market pressure before and after the reform of the Chinese exchange rate regime in 2005. We find the following stylized facts： the value of the RAIB became stable after the reform; the weight of the US dollar remained high in the basket, while other currencies remained statistically significant; and the floating band gradually increased to lO percent during 2005-2008, and then greatly narrowed from the late summer of 2008 under the assumption of a yearly resetting interval. We find that the foreign exchange market pressure increased from 2005 to 2008. A possible reason is that the weight of the US dollar in the basket was slightly lower than the share of the US dollar in total transactions on the Chinese foreign exchange market. Therefore, it is reasonable for China to adopt a dollar peg exchange rate regime.
