基于第三类危险源的风险管理计划研究

以安全管理理论、组织理论、风险管理理论为基础,在对多家煤矿实地调研的基础上,提出第三类危险源是造成组织失误的根本原因,预防第三类危险源的根本方法是编制风险管理计划;实例分析了陈家山矿某巷道实施风险管理整个过程,通过风险管理计划实施与运用,检查危险源是否在可接受风险水平下得到控制。风险管理可以对危险源的风险状态持续的检查,发现问题及时纠正,使危险源的风险状态降级,以便消除危险源。根据风险管理计划进行煤矿安全组织风险预警,其目的是为了保证煤矿安全管理组织活动处于安全、可靠的运行状态,并预测、监控、纠正各种不安全行为。陈家山矿风险管理研究对预防组织失误有现实意义。

煤矿员工的“知-能-行”不安全行为模式研究

从认知心理学视角,分析煤矿员工不安全行为的决策心理过程,构建煤矿员工不安全行为"知-能-行"模式模型,归纳该模式下煤矿员工不安全行为致因因素,为煤矿员工不安全行为管理工作提供了重要理论参考。研究表明:煤矿管理者的不尽职行为是一种重要的不安全行为,并成为导致我国煤矿事故频发的根本原因;安全管理规定和行为规范、员工的记忆状态、理解能力、行为认知能力、价值观及价值判断、行动能力均是影响煤矿员工作出不安全行为的重要心理因素;预防和控制煤矿员工不安全行为应从煤矿员工的外在规定性、"知"、"能"、"行"4个方面入手;对煤矿管理者和工人的不安全行为管理应具有差异性。     

The psychological contracts of violation victims: A post‐violation model

Organizations may fail to keep their commitments to their employees, at times leading to psychological contract violation. Although many victims of violation remain with their employer despite such adverse experiences, little research exists on their responses in the aftermath of violation. This paper develops a post‐violation model to explain systematically how violation victims respond to and cope with violation and the effects this process has on their subsequent psychological contract. Central to post‐violation are the victims' beliefs regarding the likelihood of violation resolution and the factors affecting it. The model specifies how the victim engages in a self‐regulation process that results in an array of potential psychological contract outcomes. Possible outcomes include reactivation of the original pre‐violation contract, the formation of a new contract that may be more or less attractive than the original, or a state of dissolution wherein the victim fails to form a functional psychological contract with the employer. The research and practical implications of this model are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

The power of reflection for would-be leaders: Investigating individual work reflection and its impact on leadership in teams

This paper examines the key role that individual work reflection plays in facilitating individuals' leadership in teams. Consistent with the functional perspective on leadership, we argue that individual work reflection allows individuals to better understand their team's needs, and therefore enact higher levels of task-, relational-, and change-oriented leadership behaviors and be more effective leaders in their teams. We first conducted a series of measure development studies to validate a measure of individual work reflection comprising four dimensions of reflection at work: goals-, methods-, relationships-, and self-focused reflection. Then, across two independent studies assessing individuals in self-managing teams over time, we found support for our theoretical model linking individual work reflection to peer-rated leadership behaviors (Main Studies 1 and 2) and leadership effectiveness (Main Study 2). In further support of our theorizing, Main Study 2 also indicates that individual work reflection shapes leadership behaviors and effectiveness via understanding the team's needs, beyond a wide range of related constructs (e.g., feedback seeking, mindfulness, and rumination), as well as commonly studied predictors of leadership behaviors (i.e., the Big Five). Our theory and empirical findings help advance insights on the role of individual work reflection in improving leadership outcomes in organizations.     

Prioritizing species conservation programs based on IUCN Green Status and estimates of cost-sharing potential

Over 1 million species around the world are at risk of extinction, and conservation organizations have to decide where to invest their limited resources. Cost-effectiveness can be increased by leveraging funding opportunities and increasing collaborative partnerships to achieve shared conservation goals. We devised a structured decision-making framework to prioritize species’ conservation programs based on a cost–benefit analysis that takes collaborative opportunities into account in an examination of national and global conservation return on investment. Conservation benefit is determined by modifying the novel International Union for the Conservation of Nature Green Status for Species to provide an efficient, high-level measure that is comparable among species, even with limited information and time constraints. We applied this prioritization approach to the Wilder Institute/Calgary Zoo, Canada, a nonprofit organization seeking to increase the number of species it assists with conservation translocations. We sought to identify and prioritize additional species’ programs for which conservation translocation expertise and actions could make the most impact. Estimating the likelihood of cost-sharing potential enabled total program cost to be distinguished from costs specific to the organization. Comparing a benefit-to-cost ratio on different geographic scales allowed decision makers to weigh alternative options for investing in new species’ programs in a transparent and effective manner. Our innovative analysis aligns with general conservation planning frameworks and can be adapted for any organization.     

组织定向的人因失误因果模型及影响关系研究

为了更好地从源头上预防人因失误,首先,基于系统理论发展一个组织定向人因失误的"结构-行为"因果模型,包括组织子模型、情境状态子模型、个体因素子模型以及人因失误子模型。然后,分析模型中各子模型之间以及其因素类别之间的直接和间接影响关系,如模型中各层级之间的因果关系:组织因素→情境状态因素→直接触发人因失误的个体因素→人的认知行为失误。最后,基于事件报告分析、专家意见和文献资料,并依据建立的4种影响类型(I,C,A,N)识别具体情境环境与人因失误或认知行为之间的影响关系。分析结果表明,情境环境因素对人因失误的影响非常复杂,不同的情境环境因素对同一人因失误可能产生不同类型的影响,同一情境环境因素对不同的人因失误可能产生不同类型的影响。     

硫丹的环境行为及水生态毒理效应研究进展

有机氯农药硫丹作为一种典型的持久性有机污染物(POPs)曾广泛应用于农业生产,我国曾大量使用。硫丹作为一种重要的污染物通过地表径流、淋、溶、干/湿沉降等方式进入水体,在直接影响大型水生植物和浮游藻类的同时,给鱼类等水生动物也带来了一定的毒性效应。由于其半衰期较长、迁移能力强、富集性高,在水体环境中已普遍检测出硫丹的存在,因此,对硫丹的水生生态安全性评价显得十分重要。硫丹对水生生物具有高毒性,它可影响生物正常受体配体作用、损伤生物膜、影响活性氧代谢并具有潜在的内分泌干扰作用。本文介绍了硫丹的环境行为效应,并综述了硫丹对水生生物的毒性及几种致毒机制,展望了该领域今后的研究重点和方向。
