Employee voice behavior: A meta‐analytic test of the conservation of resources framework

Although voice (i.e. expressing change‐oriented ideas and suggestions) has frequently been investigated as a way for workers to reciprocate to their employers for the positive treatment they receive, much less is known about how workers use voice to deal with stress. This study takes a conservation of resources perspective to examine the relationships among workplace stress, voice behavior, and job performance. We first examined the strength of relationships of three major groups of workplace stressors and strains (job based, social based, and organization based) with voice behavior. We then examined the relationships of voice behavior with performance variables (e.g. in‐role performance and creativity) to investigate how voice may help workers preserve or accumulate resources to enhance their performance. The meta‐analytic findings presented here provide support for a negative relationship between workplace stress and voice and a positive relationship between voice behavior and performance outcomes.

A Revealed Preference Approach to Estimating Supply Curves for Ecosystem Services: Use of Auctions to Set Payments for Soil Erosion Control in Indonesia

Abstract:  To supply ecosystem services, private landholders incur costs. Knowledge of these costs is critical for the design of conservation-payment programs. Estimating these costs accurately is difficult because the minimum acceptable payment to a potential supplier is private information. We describe how an auction of payment contracts can be designed to elicit this information during the design phase of a conservation-payment program. With an estimate of the ecosystem-service supply curve from a pilot auction, conservation planners can explore the financial, ecological, and socioeconomic consequences of alternative scaled-up programs. We demonstrate the potential of our approach in Indonesia, where soil erosion on coffee farms generates downstream ecological and economic costs. Bid data from a small-scale, uniform-price auction for soil-conservation contracts allowed estimates of the costs of a scaled-up program, the gain from integrating biophysical and economic data to target contracts, and the trade-offs between poverty alleviation and supply of ecosystem services. Our study illustrates an auction-based approach to revealing private information about the costs of supplying ecosystem services. Such information can improve the design of programs devised to protect and enhance ecosystem services.     

The dynamic response of pressure relief valves in vapor or gas service. Part II: Experimental investigation

An experimental testing program designed to evaluate the opening stability characteristics of direct acting pressure relief valves (PRV) in gas/vapor service is described. Three different valve sizes from each of three different manufacturers were tested at two different set pressures to determine their opening characteristics (disk lift vs. time). The valves were tested with several different lengths of inlet piping as well as with and without discharge piping to determine the conditions under which unstable operation (chatter) would occur. Part I of this program described a mathematical model for predicting the dynamic response of PRV's, and the data described in this test program were used to evaluate the accuracy of the model, as described in Part III of this study to follow.     

安全工程本科专业建设研究的文献计量学分析

为了解安全科技人员利用文献的特点和安全工程学科文献的发展规律,根据文献计量学分析理论与方法,对1995—2009年安全工程本科专业建设研究文献的发文量、文献著者、核心作者群、核心期刊群、引文文献、被引用情况和基金项目资助等进行分析研究,结果表明:安全工程本科专业建设研究的发文量较少但整体呈上升态势;文献著者的合作度为2.5,合著率76.1%,文献的合作度和合著率较低,研究深度和广度需进一步加强,同时需加强多单位联合研究;高校研究者是该领域的主力军,其发文量占92.5%,但核心作者群尚未形成;《中国安全科学学报》是该领域研究的核心期刊,北京是该领域研究的核心区域;期刊文献是主要的引文类型(73.5%),引文语种主要是中文文献(97.3%),篇均引文文献4.9篇,普赖斯指数较高(73.3%);文献的被引用频次整体较低(2.2);2005年以来文献的基金项目资助率为30.2%,基金项目资助率和资助项目级别均呈上升趋势。

Women executives and off-the-job misconduct by high-profile employees: A study of National Football League team organizations

The risk of off-the-job misconduct by high-profile employees is a serious concern of top management in professional sport organizations, media and entertainment companies, and public-facing entities in the government and education sectors. Yet there is little research on how to prevent or mitigate this form of misconduct in organizations. Utilizing upper echelons theory and the literature on demographic composition, we examine the relationship between the gender composition of executives of team organizations in a men's professional sport league and subsequent misconduct by players on those teams. Specifically, we employed multilevel and logistic regression analyses to unique data on U.S. National Football League team organizations, and we found that firms with a critical mass of women executives experienced fewer player arrests. No support was found for executive power as a moderator of this relationship. We discuss the implications of our findings for the demographic composition literature. We also offer guidance for preventing and managing off-the-job misconduct by high-profile employees.
