Employees' perceptions of organizational restructuring: The role of social support

Organizational change and restructuring is often perceived as leading to increased occupational stress, impacting negatively on the psychological well-being of employees. This pragmatic study investigates the role of social support and dispositional affect as moderators of role stress post-restructuring for employees in a public utility company. A total of 176 employees, including 37 managers, 60 graded staff and 78 industrial staff completed a self-report questionnaire, approximately 1 year postrestructuring, retrospectively assessing role conflict, ambiguity, overload and positive and negative feedback pre- and post-restructuring. Results suggested that overall role stress increased for managers/ senior officers and graded staff, but not for industrial staff. Social support was linked with lower role stress, more positive feedback and less negative feedback at post-restructuring. For certain role stressors this impact was moderated by dispositional affect, but the effect was not consistent across occupational groups. Positive affect enhanced the effect of manager support in reducing role conflict for graded staff, and the effect of co-worker support in increasing positive feedback and reducing negative feedback for industrial staff. Findings suggest that managers should pay particular attention to support and feedback for employees during periods of chronic occupational stress following organizational restructuring.     

On positive harris recurrence of stochastic fluid networks

The stochastic fluid networks we consider here are open multiclass fluid networks with Markov-modulated inflow rate. They are typically used as models for manufacturing and telecommunication systems. The main aim of this paper is to investigate the question of positive Harris recurrence of the joint process of buffer content and inflow rate. It will turn out that a Markovian server allocation exists under which the process is positive Harris recurrent if the usual traffic conditions are satisfied on average. Moreover, for special networks like single-server networks, re-entrant lines and Jackson networks it is possible to show that certain service disciplines induce positive Harris recurrent state processes. As a by-product we show that these stochastic fluid networks converge under appropriately defined scaling to solutions of deterministic fluid models.

Double samble tests— a distribution free procedure

A method for constructing two-stage (double samble) tests is presented which does not require the evaluation of complicated bivariate distribution function. The procedure results from a modification of Fisher's method for combining independent tests of significance and is distribution free in the way it combines the test results from the two sampies. However, the one sample test statistics for the two samples are assumed to have continuous distributions and may be parametric. A rule is also given or the selection of a particular test out of a family of possible two-stage tests which can be generated by this method. Specific examples are given and comparisons are made with two double sample tests which have previously been presented in the literature.     

Bayesian Robustness of the Positive False Discovery Rate

The positive false discovery rate was introduced by Storey (2003 Storey , J. D. (2003). The positive false discovery rate: a Bayesian interpretation and the q-value. Ann. Statist. 31:2013–2035.[Crossref], [Web of Science ®] , [Google Scholar]) as an alternative to the family wise error rate for the case in which we are simultaneously testing a large amount of hypotheses. The positive false discovery rate has a very nice Bayesian interpretation (as it was shown by Storey, 2003 Storey , J. D. (2003). The positive false discovery rate: a Bayesian interpretation and the q-value. Ann. Statist. 31:2013–2035.[Crossref], [Web of Science ®] , [Google Scholar]) and its robustness is analyzed. The emphasis is on the ε-contamination class (one of the most used classes of priors for Bayesian robustness) and it is shown that robustness is not obtained when the basic prior concentrates the probability on the null hypothesis.     

Bivariate Aging Properties under Archimedean Dependence Structures

Let X  = (X, Y) be a pair of lifetimes whose dependence structure is described by an Archimedean survival copula, and let X _t  = [(X ? t, Y ? t) | X > t, Y > t] denotes the corresponding pair of residual lifetimes after time t ≥ 0. Multivariate aging notions, defined by means of stochastic comparisons between X and X _t , with t ≥ 0, were studied in Pellerey (2008 Pellerey , F. ( 2008 ). On univariate and bivariate aging for dependent lifetimes with Archimedean survival copulas . Kybernetika 44 : 795 – 806 .[Web of Science ®] , [Google Scholar]), who considered pairs of lifetimes having the same marginal distribution. Here, we present the generalizations of his results, considering both stochastic comparisons between X _t and X _t+s for all t, s ≥ 0 and the case of dependent lifetimes having different distributions. Comparisons between two different pairs of residual lifetimes, at any time t ≥ 0, are discussed as well.

陈染：肯定性书写——女性性主体意识

阐明女性经验可以使历史上主要为男性利益服务的文化价值体系具有人性并得到平衡,也就是说,它能够带来男女文化上的双性。所以觉醒的女作家一反男性传统文学的创作方法和美学原则,加强对女性内在体验与性的主体欲望的书写,用以颠覆和反抗菲勒斯中心主义对女性的压抑与禁锢。
