高级管理人员变更、股权特征与盈余管理——来自中国上市公司的经验证据

本文以2003-2006年我国A股上市公司为研究样本,检验公司发生高级管理人员变更时的盈余管理行为。研究结果表明,发生高级管理层变更的公司,高级管理人员变更的当年存在较严重的调减利润的盈余管理行为;此外,对于发生了高级管理人员变更的公司,如果其控股股东是地方和中央政府部门所属国企或中央直属国企,则其调减利润的盈余管理行为可以得到一定程度的抑制;大股东的制衡度越大,公司盈余管理的幅度也将越小。研究结果还显示,当发生高级管理人员变更时,上述因素对公司调增利润的盈余管理行为基本没有影响。

Zimbabwe's AIDS action programme for schools

AIDS education started very early in Zimbabwe and is now compulsory in all schools. This evaluation documents the development of the primary and secondary school AIDS Action Programme from 1991 to 1998. Six programme aspects were evaluated: programme start-up, planning and management, development of syllabi and materials, teacher training, research, monitoring and evaluation, and co-ordination. The Programme drew on resources from within the existing educational system. Due to broad-based consultation and participation, it was supported by Government and partners. Flexible management ensured implementation of mid-course corrections. It was concluded that school AIDS programmes should stress participatory teaching and learning methods and life-skills training. Curriculum writers and teachers needed training and supervision in participatory techniques. Cluster workshops between district and school levels were needed to strengthen the cascade model of teacher training that had been adopted. Systematic research, monitoring and evaluation were essential, including follow-ups to baseline surveys. The Zimbabwean programme was well-designed, relatively inexpensive and replicable.     

Employee stress litigation: The UK experience

This paper considers the extent to which stress-induced illness can be regarded as a personal injury that could give rise to civil action for damages against employers in the UK. It outlines the results of a brief survey of personal injury solicitors, which indicates that claims are already being initiated by employees who allege they have suffered a stress-induced illness. The potential for claims within industrial tribunal cases that have already been decided is also examined. Consideration is given to the hurdles that litigants will have to surmount, such as proving that their condition was in fact caused by some feature of their working conditions, showing that it was foreseeable that they would suffer a stress-based injury, and demonstrating that their employer was in some way at fault. This leads to a questioning of what employers can do to protect themselves from such claims, or at least defend them successfully. The paper points out that success is likely to depend heavily upon the quality of expert medical opinion, and also upon policy conditions that may influence those adjudicating on such cases. It is concluded that the cost of losing claims may be significant, and that employees who ignore the warning signs do so at their peril.     

Writing from practice

This study investigates the effects of integration change on the integration success of German acquisitions in Poland. It is argued that the degree of integration change has a positive impact on two success measures, namely, economic growth and efficient co-operation, in the acquisition target. It is further argued that process transparency, participation and positive reinforcement are moderators in this relationship between degree of integration change and integration success. Hypotheses are tested on 521 Polish employees from twenty-nine German acquisitions made in Poland between 1991 and 1999. The results show that there was a positive relationship between degree of integration change and integration success as expected and that only process transparency emerged as a significant moderator of this relationship. Consequences for post-acquisition management after German acquisitions in Poland and limitations of the study are discussed.     

Mediating role of citizen empowerment in the relationship between participatory monitoring and evaluation and social sustainability

The paper explores the mediating influence of citizen empowerment on the relationship between participatory monitoring and evaluation (PM&E) and social sustainability as a contribution to the ongoing debate on sustainability. The empirical investigation took the form of mixed-methods approach with the objectives to determine the extent to which PM&E influences citizen empowerment; establish the extent to which citizen empowerment influences social sustainability; and establish the joint influence of PM&E and citizen empowerment on social sustainability. The study employed a concurrent parallel design, in which samples for quantitative and qualitative components were different but drawn from the same population, and data collected within the same timeframe. Quantitative data were analyzed through bivariate and multiple regression analyses. Conversely, the qualitative component utilized interpretive technique and recursive abstraction to organize, summarize and give impression on the causal mechanisms at play in the quantitative data. Evidence from the study revealed that citizen empowerment mediates the relationship between PM&E and social sustainability. The study also found that when PM&E and citizen empowerment are considered together, citizen empowerment seems to have a dominant influence on social sustainability than PM&E itself. Thus, the government and development practitioners should prioritize citizen empowerment as a precursor to the realization of social sustainability outcomes.     

The Interdisciplinary Future of Supply Chain Management Research

Since the term supply chain management (SCM) was first introduced over 30 years ago, the field of SCM has undergone numerous transformations. Today, it is a prevailing theme in scholarly and popular research, and numerous disciplines claim its ownership. However, current and emerging SCM research challenges are becoming increasingly more complex. Fragmented and "siloed" research efforts across a range of disciplines may not be adequate to address the full complexities associated with these phenomena. We interviewed 50 SCM academic thought leaders, across a range of disciplines, and 20 SCM executives with the goal of helping researchers develop a consistent stream of work that builds on existing research, identifies relevant research directions, and provides guidance for the future. Although there were some differences in opinions, there was consensus on the boundary characteristics of SCM, as well as the identification of interdisciplinary research (IDR) as necessary for the enablement of SCM to address the numerous current and emerging intractable SCM challenges. In this article, we present these findings and provide a path forward based on the collective wisdom of these academics and executives.     

Retailer Transshipment versus Central Depot Allocation for Supply Network Design

We consider a supply chain structure with shipments from an external warehouse directly to retailers and compare two enhancement options: costly transshipment among retailers after demand has been realized vs. cost‐free allocation to the retailers from the development of a centralized depot. Stochastic programming models are developed for both the transshipment and allocation structures. We study the impact of cost parameters and demand coefficient of variation on both system structures. Our results show an increasing convex relationship between average costs and demand coefficient of variation, and furthermore that this increase is more pronounced for the allocation structure. We employ simulation and nonlinear search techniques to computationally compare the cost performance of allocation and transshipment structures under a wide range of system parameters such as demand uncertainty and correlation; lead times from the external warehouse to retailers, from warehouse to central depot, and from depot to retailers; and transshipment, holding, and penalty costs. The transshipment approach is found to outperform allocation for a broad range of parameter inputs including many situations for which transshipment is not an economically sound decision for a single period. The insights provided enable the manager to choose whether to invest in reducing lead times or demand uncertainty and assist in the selection of investments across identical and nonidentical retailers.
