管理控制中管理者的行为特征分类及管理业绩的关系研究

以心理学、组织行为学、管理学为理论基础,以价值观、态度、动机为行为特征的划分变量,对企业管理控制中管理者不同群体的行为特征进行了实证研究。通过聚类分析将控制对象划分为集体主义倾向型、规则顺从型、自我价值实现型和环境认知型4类人群,研究显示每一类群体都呈现出差异化的人口统计特征。然后,进一步考察了这4类群体的管理业绩与"目标难度适度性"、"信息反馈及时性"及"业绩考核公平性"等控制环节的关系。     

中国人的上下级关系:整合构念的建立与初步检验

为建立更整合的SSG构念,基于多维度人际关系理论,提出SSG三维构念,认为上下级关系指在某一时刻存在于上下级之间的基于利益、情感和身份义务的连结。工具性、情感性、义务性是构成上下级关系的3个维度,由此发展出SSG类型构念初始模型。为检验理论,以调查与案例混合法收集并分析39对上下级关系的相关信息,基于分析结果形成SSG类型构念修正模型。经检验,修正后的SSG类型构念与案例有较高的相符程度。最终形成的SSG构念理论包括构念界定、维度内涵、维度的动态发展、维度构念与类型构念的对应关系和类型描述等内容。     

中庸结构内涵及其与集体主义关系的研究

基于4批共949份调查问卷数据,首先探索目前中国情境下中庸价值取向的结构内涵,得到“执中一致、慎独自修、消极成就、消极规避”4个维度,其中,“执中一致”是中庸结构内涵的核心,描述了个体与周围情境互动时的价值取向.然后,基于参照框架效应理论发现,相比于集体主义,中庸能更为有效解释中国员工的帮助行为;在高和谐导向氛围的情境下,中庸对集体主义有显著的促进作用.     

家长式领导对高层管理团队成员创造力的作用机制研究

基于对57个高科技企业高层管理团队中的配对数据分析,对家长式领导行为、心理授权、权力距离和集体主义价值观影响高层管理团队成员创造力的方式进行探究。研究发现,CEO的家长式领导行为对团队成员创造力具有显著的正向影响,团队成员的心理授权在其中起完全中介作用。此外,家长式领导对不同价值取向的团队成员的心理授权产生了不同的影响,即团队成员的权力距离取向越高,或者集体主义取向越高,威权领导对其心理授权的负向影响越弱;团队成员的集体主义取向越高,仁慈领导对其心理授权的正向影响越弱。     

家族期望落差与创业退出：基于中国数据的分析

作为创业过程的重要活动之一, 创业退出并未引起学者太多的关注, 大多数现有研究文献从企业家、企业、行业和宏观环境去分析创业退出的原因, 而忽略了创业家族的影响.本文以家族期望作为分析单元, 从理论上探讨了家族期望落差与创业退出之间的关系, 以及寻租活动在其间的传导效应.本文的经验分析主要得到了以下研究结论: (1) 新创企业的创始人及其家族具有多重期望目标, 包括家族财富、家族声望、家族团结以及人丁兴旺期望的实现. (2) 家族期望落差对企业家是否选择创业退出具有显著的影响, 即家族的财富丰腴、团结和谐和社会声望期望落差越大则家族企业创始人越倾向于退出经营领域, 而人丁兴旺期望落差越小则越有可能坚持创业. (3) 寻租行为在家族期望落差与创业退出之间起中介传导效应, 即家族期望的未实现将导致企业主倾向于选择非法性寻租行为, 而寻租的高成本与潜在的风险则会进一步增加其退出创业的可能性.     

虚拟社区内不同群体的知识贡献行为:一项对比研究

中老年群体正在成为虚拟社区知识贡献的新主体,但不同群体在虚拟社区内的知识贡献行为究竟有何差异目前尚缺乏有针对性的研究。基于社会认知理论,本文设计了关于环境对虚拟社区知识贡献影响的假设模型,使用不同群体的数据对假设进行了验证。分析并解释了年轻人与年长者在机制上的差异,发现线上互动、线下互动作为环境,对知识贡献的影响机制不同;分析了不同群组构念均值得分的差异,发现年轻人在期望收益及自我效能上要强于年长者,但知识贡献差异不显著,说明年长者热心于知识贡献行为,且他们对收益的预期低于年轻人,这对于开发老年人力资源有很好的启示意义。本文比较了虚拟社区内不同用户群体行为的差异,有助于丰富在线知识管理的对比研究,为虚拟社区用户管理提供参考。     

供应商网络形态构念及实证研究

依据嵌入性理论,从结构嵌入、关系嵌入、认知嵌入和规范嵌入4个层面,对制造企业供应商网络形态构念进行理论分析,归纳并初步提取制造企业供应商网络形态构念的主要要素.在此基础上结合企业访谈,开发供应商网络形态构念的测量工具.以中国制造企业为研究对象,进行大样本问卷调查,利用SPSS软件对回收的有效问卷进行探索性因子分析,得出供应商网络形态构念的5个维度,利用SPSS和AMOS软件对由该5个维度组成的供应商网络形态测量量表进行检验.研究结果表明,供应商网络形态测量量表具有较好的信度和效度,供应商网络形态由认知一致性、组织之间关系、协调机制、网络位置和网络结构5个维度组成.研究开发的供应商网络形态测量量表实现了对供应商网络形态构念的定量测量,为制造企业供应商网络形态的研究提供可借鉴的测量工具,有利于对制造企业设计和管理供应商网络问题进行更深入和广泛的研究.     

IT服务企业中文化对知识共享与创新行为关系的影响

在全球一体化进程加速、IT服务企业员工文化价值取向趋于多元化的背景下,有必要了解员工文化观念对企业的影响。本文研究员工的集体主义观念和权力距离观念对IT服务企业中知识共享与创新行为之间关系的影响。在北京、西安的具有不同文化特色的IT服务企业进行问卷调查,收集了484份问卷,运用SPSS及SmartPLS进行数据分析。研究结果表明:员工的集体主义观念增强时,知识共享对创新行为的影响会增加;权力距离增大时,知识共享对创新行为的影响会减弱。对实践的启示是:管理者应培养、提高员工的集体主义文化价值观;根据公司的企业文化特色,区分对待员工权力距离对知识共享与创新行为之间关系的影响作用。     

重大公共威胁情境下个体亲社会行为形成机制———以新冠疫情为例

现有研究对于威胁情境和个体亲社会行为的关系并未达成共识.对于两者之间的关系,本研究以新冠肺炎疫情为具体研究情境,从威胁情境的时间和类型两个角度填补了以往研究的空白,以内群体认同和关注他人为中介机制,提出重大公共威胁情境下影响个体捐赠意愿的双路径形成机制和相关调节变量.本文的研究表明,对于新冠疫情这种捐赠方和受助方同时面对的公共威胁情境:1)潜在捐助者所在地的疫情严重程度对其捐赠意愿的影响没有显著差异.2)群体认同和关注他人具有相反的中介作用,其掩盖了潜在捐助者所在地的疫情严重程度对其捐赠意愿的影响;本地疫情严重程度一方面会增强个体的内群体认同继而正向影响捐赠意愿,另一方面会使个体减少关注他人继而减弱其捐赠意愿.3)威胁情境影响过程中,区域文化取向调节了内群体认同的正向中介作用和关注他人的负向中介作用.具体而言,相较于偏个体主义,当区域文化取向为偏集体主义时,本地疫情严重程度对于内群体认同的正向影响能够增强,对于关注他人的负向影响能够减弱.     

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.     

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.     

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.
