构建高层管理团队社会网络的人力资源实践、战略柔性与企业绩效——环境不确定性的调节作用

本文首次将战略柔性作为一种典型的动态能力运用到战略人力资源管理的研究领域中,探索了其在构建高层管理团队(TMT)社会网络的人力资源实践与企业绩效关系中所扮演的中介作用,并且基于我国经济转型这一现实背景,采用环境不确定性作为该中介环节的调节变量予以进一步阐释.我们对上述问题进行了实证检验,通过对北京、天津、上海、江苏和浙江等地区390家企业的780名高管进行问卷调查,最终获得241个有效样本,研究发现:(1)构建TMT社会网络的人力资源实践对企业绩效具有正向影响,并且战略柔性在其中发挥了完全中介的作用;(2)环境不确定性在构建TMT社会网络的人力资源实践与战略柔性的关系中具有调节作用,但在战略柔性与企业绩效的关系中不具有调节作用.本文的研究结论表明,考虑战略柔性和环境不确定性这两个重要因素可以更好地解释构建TMT社会网络的人力资源实践对企业绩效的影响机制,这为战略人力资源管理在动态环境中的发展和应用提供了重要启示.     

管制放松后的企业竞争行动、竞争对手分类与销售绩效

基于亚洲14个国家(地区)电信企业的二手数据,本文检验了企业竞争行动与销售绩效之间的主效应,以及组内竞争和组间竞争对上述主效应的调节作用。研究发现,企业竞争行动密集性、异质性与销售绩效正相关,企业竞争行动简单性与销售绩效负相关;市场竞争(包括组内竞争与组间竞争)对企业竞争行动密集性、异质性与销售绩效之间的关系存在负向调节,对企业竞争行动简单性与销售绩效之间关系存在正向调节。从3个战略群组的对比看,在企业成员规模越小的战略群组中,组内竞争对企业竞争行动与销售绩效之间关系的调节效应越强;在企业成员规模越大的战略群组中,组间竞争对企业竞争行动与销售绩效之间关系的调节效应越强。上述结论表明,组内竞争对小企业最为不利,组间竞争对大企业最为不利。     

HRM系统、竞争战略与企业绩效关系的实证研究

战略人力资源管理理论认为人力资源管理(HRM)系统和企业竞争战略之间的匹配关系会对企业绩效产生影响.通过类型学和分类学两条主线归纳并总结了关于 HRM 系统及其与企业绩效关系的研究,提出了 HRM 系统、竞争战略与企业绩效关系的假说,并以133家样本企业为研究对象,对理论假说进行了检验.研究发现,采取内部型 HRM 形态的企业的绩效高于采取市场型 HRM 形态的企业;环境特征(产业技术变革、劳动力市场竞争)对 HRM 系统形态与企业绩效关系的调节效应仅得到部分支持,而企业规模的调节效用没有得到支持;企业的竞争战略对人力资源战略选择的影响很小;HRM 系统与竞争战略匹配企业的绩效高于没有匹配企业的假说没有得到支持.最后,对研究结论进行了讨论,分析了其局限性和未来研究建议.     

科技型小微企业应用性学习与成长绩效

以广东顺德地区130家科技型小微企业为研究对象,运用结构方程模型(SEM)和多元回归分析方法对应用性学习、成长绩效与环境动荡性之间的关系进行了实证研究。结果表明,应用性学习对成长绩效有正向影响,科技型小微企业通过开展应用性学习可以获得良好的成长绩效;环境动荡性对应用性学习与成长绩效间关系存在负向调节作用,当环境动荡性较高时,应用性学习对成长绩效的促进作用较弱。根据这一结论,通过实践案例,从企业和政府2个角度出发,给出了相应的启示和对策。     

中小型制造企业竞争优先权关系实证研究

制造战略竞争优先权关系研究是制造战略研究的重要分支.中小企业作为企业群体的重要的组成部分,有着高效率、高灵活性等一系列优点.本文将从中小型企业的角度出发,对该类企业的战略竞争优先权进行验证性实证分析.本文结合2001年国际制造战略调查(IMSS)数据样本,运用因子分析、相关分析和回归分析等方法研究企业竞争优先权之间的关系以及竞争优先权与绩效之间的关系,构建了竞争优先权和绩效关系模型.结果显示,中小型制造企业竞争优先权关系符合累积关系,但累积关系排序与以往的研究结果不一致;在企业绩效方面,重视多种竞争能力的企业优于那些重视单一能力的企业.     

组织学习、战略柔性对企业绩效影响的实证研究

通过对组织学习能力、战略柔性及企业绩效的相关文献的系统梳理,探索性地提出了一个体现组织学习能力、战略柔性以及企业绩效之间关系的结构模型,采用多行业的样本数据,运用SPSS和结构方程模型,通过样本分析,检验了组织学习能力对不同类型的战略柔性(资源柔性和能力柔性)的影响,以及资源柔性和能力柔性分别对于企业绩效的影响;通过假说验证分析,辅助各变量R2值的分析,企业绩效的53.6%被战略柔性的影响作用所解释,又由于资源柔性对企业绩效的影响作用不显著,所以被解释的企业绩效很大程度上源于能力柔性的影响.研究表明确实存在组织学习能力对战略柔性的影响作用,以及不同类型的战略柔性(资源柔性和能力柔性)对企业绩效影响的差异,从而为企业提高经营绩效提供理论基础和有效途径.     

产品模块化对企业竞争优势的影响机理研究

利用珠三角大中型制造企业的调查数据,分别检验了战略柔性(先动柔性、响应柔性)、环境动态性在产品模块化(模块化设计、模块化生产)与竞争优势(品牌优势、大规模定制优势)间的中介与调节作用。结果表明:产品模块化对竞争优势有显著正向影响;产品模块化通过战略柔性完全中介作用于品牌优势;响应柔性在模块化设计、模块化生产与大规模定制优势的关系中分别起完全和部分中介作用,先动柔性则没有;环境动态性正向调节模块化生产与品牌优势的关系,负向调节模块化设计与竞争优势的关系,而在模块化生产与大规模定制优势关系中的调节作用不显著。

Criteria for selecting a production control philosophy

Logistic objectives constitute a compromise between having short leadtimes and a low volume of work in progress on the one hand and a high resource loading and due date obligation on the other. Miscellaneous production planning approaches offered today provide different combinations of logistic objectives for satisfying a manufacturing strategy. To combine the strength of the various approaches into a unified system, a new approach based on a dynamic and distributed production planning methodology is proposed. To customize the approach, various analyses and specifications have to be made and for that reason some important characteristics and criteria for analysing production control philosophies will be given.     

The social construction of the meaning of acute stressors: a qualitative study of the personal accounts of police officers using a stress counselling service

The police profession is one in which acute stressors are encountered more frequently than in other occupations. Using the personal accounts of 35 police officers attending an in-house stress counselling clinic, the aim of the present study was to provide a qualitative examination of how the institutional context of policing influenced the ways in which acute stressors signified to individual police officers experiencing felt distress. Using the framework of Rational Emotive Behaviour Therapy as an analytical tool, it is argued that beliefs contributing to the experience of felt distress are related to the way in which policing as both an identity and an activity is constructed through the police organizational culture. Not only do these constructions influence the ways in which officers perceive themselves and their environments, but they also operate at the collective level to 'normalize' some emotional responses and to 'pathologize' others which, it is argued, could impact upon the outcomes of interventions such as stress counselling.     

The moderating role of social support in Karasek's job strain model

This paper examines whether social support is a boundary-determining criterion in the job strain model of Karasek (1979). The particular focus is the extent to which different sources of social support, work overload and task control influence job satisfaction, depersonalization and supervisor assessments of work performance. Hypotheses are tested using prospective survey data from 80 clerical staff in a university setting. Results revealed 3-way interactions among levels of support (supervisor, co-worker, non-work), perceived task control and work overload on levels of work performance and employee adjustment (self-report). After controlling for levels of negative affect in all analyses, there was evidence that high levels of supervisor support mitigated against the negative effects of high strain jobs on levels of job satisfaction and reduced reported levels of depersonalization. Moreover, high levels of non-work support and co-worker support also mitigated against the negative effects of high strain jobs on levels of work performance. The results are discussed in terms of the importance of social support networks both at, and beyond, the work context.     

Job insecurity, coping resources and personality dispositions in occupational strain

This paper presents research on the relationships between the work-related stressor of perceived job insecurity and various indicators of occupational strain, taking into account employees' personality dispositions (trait negative and positive affectivity) and coping resources. Respondents were 222 Australian public servants surveyed during organizational restructuring that involved downsizing and threat to job certainty. The research was formulated within an adaptation of Osipow, Doty, and Spokane's (1985) framework of stress-strain-coping that included the possible direct as well as moderating effects of personality dispositions in reporting occupational strain (Parkes, 1990). Findings from hierarchical regression analyses indicate consistent significant independent effects of personality dispositions, coping resources and perceived job insecurity on various indicators of strain. There was also support for the moderating roles of negative affectivity and self-care in the relation between perceived job insecurity and physical strain. Implications for the role of dispositional factors, especially negative affectivity, and the utility of various coping resources in accounting for occupational strain in times of threatened job security are discussed.     

Introduction to Special Section on Sensitivity Analysis and Summary of NCSU/USDA Workshop on Sensitivity Analysis

This guest editorial is a summary of the NCSU/USDA Workshop on Sensitivity Analysis held June 11–12, 2001 at North Carolina State University and sponsored by the U.S. Department of Agriculture's Office of Risk Assessment and Cost Benefit Analysis. The objective of the workshop was to learn across disciplines in identifying, evaluating, and recommending sensitivity analysis methods and practices for application to food‐safety process risk models. The workshop included presentations regarding the Hazard Assessment and Critical Control Points (HACCP) framework used in food‐safety risk assessment, a survey of sensitivity analysis methods, invited white papers on sensitivity analysis, and invited case studies regarding risk assessment of microbial pathogens in food. Based on the sharing of interdisciplinary information represented by the presentations, the workshop participants, divided into breakout sessions, responded to three trigger questions: What are the key criteria for sensitivity analysis methods applied to food‐safety risk assessment? What sensitivity analysis methods are most promising for application to food safety and risk assessment? and What are the key needs for implementation and demonstration of such methods? The workshop produced agreement regarding key criteria for sensitivity analysis methods and the need to use two or more methods to try to obtain robust insights. Recommendations were made regarding a guideline document to assist practitioners in selecting, applying, interpreting, and reporting the results of sensitivity analysis.     

Job stress, job strain, and psychological withdrawal among Dutch university staff: towards a dualprocess model for the effects of occupational stress

This study examined the antecedents of job strain (emotional exhaustion, health complaints) and withdrawal behaviour (e.g. lowered organizational commitment) among a cross-sectional sample of 131 academic staff members of the law department of a large Dutch university. Conservation of resources theory (Hobfoll, 1989) provided the theoretical background for this study. Strains and withdrawal behaviours were expected to be most prominent among those who reported having few resources and/or who reported high job demands. Structural equation modelling revealed that this was indeed the case. As predicted, differential patterns of effects emerged for job demands and job resources. Analysis of the effects of four job-specific stressors revealed that especially the structural aspects of a staff member's teaching task (e.g. the number of students in their classes) contributed strongly to perceived job demands. Theoretical and practical implications of the study are discussed.     

Distinguishing traumatic, vicarious and routine operational stressor exposure and attendant adverse consequences in a sample of police officers

Problems in studying occupational stress within the police service are identified and the paucity of work on operational duties as potential stressors are discussed. The present study reports the results of a factor analysis of operational stressors (N = 601 serving British police officers) that revealed three factors: exposure to death and disaster; violence and injury; sexual crime. These were demonstrated to be reliable scales and were included in logistic regression models together with a range of demographic and psychological variables. Models were applied to men and women separately, which showed there to be different predictors of the likelihood of suffering distress (measured by the General Health Questionnaire, GHQ) in terms of the officer's gender and operational role. Overall the model for women officers was better at predicting psychological distress than that for men. These findings are related to aspects of the police occupational culture. Further discussion is offered that conceptualizes police operational stressors as traumatic, routine and vicarious. Finally, some implications are drawn for the provision of stress intervention in the light of this differentiation.     

Dermal Uptake of 18 Dilute Aqueous Chemicals: In Vivo Disappearance‐Method Measures Greatly Exceed In Vitro‐Based Predictions

Average rates of total dermal uptake (K_up) from short‐term (e.g., bathing) contact with dilute aqueous organic chemicals (DAOCs) are typically estimated from steady‐state in vitro diffusion‐cell measures of chemical permeability (K_p) through skin into receptor solution. Widely used (“PCR‐vitro”) methods estimate K_up by applying diffusion theory to increase K_p predictions made by a physico‐chemical regression (PCR) model that was fit to a large set of K_p measures. Here, K_up predictions for 18 DAOCs made by three PCR‐vitro models (EPA, NIOSH, and MH) were compared to previous in vivo measures obtained by methods unlikely to underestimate K_up. A new PCR model fit to all 18 measures is accurate to within approximately threefold (r = 0.91, p < 10^?5), but the PCR‐vitro predictions (r > 0.63) all tend to underestimate the K_up measures by mean factors (UF, and p value for testing UF = 1) of 10 (EPA, p < 10^?6), 11 (NIOSH, p < 10^?8), and 6.2 (MH, p = 0.018). For all three PCR‐vitro models, log(UF) correlates negatively with molecular weight (r² = 0.31 to 0.84, p = 0.017 to < 10^?6) but not with log(vapor pressure) as an additional predictor (p > 0.05), so vapor pressure appears not to explain the significant in vivo/PCR‐vitro discrepancy. Until this discrepancy is explained, careful in vivo measures of K_up should be obtained for more chemicals, the expanded in vivo database should be compared to in vitro‐based predictions, and in vivo data should be considered in assessing aqueous dermal exposure and its uncertainty.     

Systems Resilience for Multihazard Environments: Definition,Metrics, and Valuation for Decision Making

The United Nations Office for Disaster Risk Reduction reported that the 2011 natural disasters, including the earthquake and tsunami that struck Japan, resulted in $366 billion in direct damages and 29,782 fatalities worldwide. Storms and floods accounted for up to 70% of the 302 natural disasters worldwide in 2011, with earthquakes producing the greatest number of fatalities. Average annual losses in the United States amount to about $55 billion. Enhancing community and system resilience could lead to massive savings through risk reduction and expeditious recovery. The rational management of such reduction and recovery is facilitated by an appropriate definition of resilience and associated metrics. In this article, a resilience definition is provided that meets a set of requirements with clear relationships to the metrics of the relevant abstract notions of reliability and risk. Those metrics also meet logically consistent requirements drawn from measure theory, and provide a sound basis for the development of effective decision‐making tools for multihazard environments. Improving the resiliency of a system to meet target levels requires the examination of system enhancement alternatives in economic terms, within a decision‐making framework. Relevant decision analysis methods would typically require the examination of resilience based on its valuation by society at large. The article provides methods for valuation and benefit‐cost analysis based on concepts from risk analysis and management.
