How transformational leadership influences follower helping behavior: The role of trust and prosocial motivation

We proposed and tested a moderated mediation model that jointly examines affect‐based and cognition‐based trust as the mediators and prosocial motivation as the moderator in relationships between transformational leadership and followers’ helping behavior towards coworkers. Data were collected from 348 sales and servicing employees and their supervisors in four private retail companies and five private manufacturing companies located in Southeast China. The results showed that both affect‐based trust and cognition‐based trust mediated the relationship between transformational leadership and followers’ helping behavior towards coworkers. Furthermore, moderated mediation analyses showed that affect‐based trust mediated the relationship between transformational leadership and followers’ helping behavior towards coworkers only among employees with high prosocial motivation, whereas cognition‐based trust mediated this relationship among only those with low prosocial motivation. Implications for the theory and practice of leadership are then discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

基于杜邦STOP系统及行为安全理论的非煤矿山不安全行为研究

非煤矿山是典型的高危行业。为了规范作业人员的不安全行为,预防和减少生产事故,基于杜邦STOP系统及行为安全理论,通过行为观察、行为聚类,构建了非煤矿山不安全行为管理模型。对某大型非煤地下矿山的14类工种作业为期70天跟踪观察,收集统计生产作业中的不安全行为,通过分类整理,形成不同类别的不安全行为比例变化趋势图。结果表明:动力设备类、防护坠落类和其它类的不安全行为有明显的降低趋势;生产工艺类、常识危险类和供电系统类的不安全行为改善不明显。实例表明,基于杜邦STOP系统及行为安全理论的非煤矿山不安全行为研究具有实效性。     

基于RBI技术的化工装置压力管道风险评估与在线检验策略研究

基于RBI方法原理,实施化工装置压力管道风险评估。在风险评估过程中,将装置内各腐蚀回路中的压力管道按照管径、材质及用途等因素进行分组,以得到各压力管道组的风险等级,在此基础上确定其抽检比例,制订在线检验策略。以某厂环氧乙烷/乙二醇〖JP2〗（EO/EG）装置为对象,应用壳牌S-RBI软件完成装置内274组（共458条）压力管道风险评估工作,根据风险评估结果共抽取178条压力管道实施在线检验,考虑到该装置存在的减薄机理,在线检验技术手段以测厚和宏观检查为主,并对部分中高风险等级以上的压力管道进行数字射线检测。检验结果表明:基于RBI技术的压力管道在线检验策略能够有效发现压力管道系统中存在的安全隐患,并节约检验成本。     

基于Multi-agent的矿工情绪稳定性模型构建

为解决由矿工情绪稳定性水平低下引起的不安全行为问题,基于复杂适应系统（CAS）理论和多主体建模与仿真（ABMS）的方法,构建矿工情绪稳定性水平提升模型。通过调节班组协调程度、组织公平程度、安全心理培训水平、受教育程度、个性特征和作业环境舒适度,在NETLOGO仿真平台上分析矿工意志强度、情绪安全倾向度以及管理者领导能力对矿工情绪稳定性水平的影响。研究表明:矿工的情绪稳定性水平提升系统是一种典型的复杂适应系统,矿工情绪稳定性水平是各主体属性相互作用的结果,作用程度存在差异。因此,煤炭企业应考虑各种因素,通过控制和改善各主体的行为以提高矿工情绪稳定性水平。     

Local‐level governance of risk and resilience in Nepal

This paper explores the circumstances in which communities may effectively reduce risks. It draws on the example of two ‘Risk and Resilience Committees’ (RRCs) that were established in Nepal as part of an action research project: one in Panchkhal in the central region, operating as a community‐based organisation (CBO); and the other in Dhankuta in the eastern region, embedded in municipal government. In‐depth interviews were conducted with RRC members. Wider community preferences for risk reduction were examined through a questionnaire survey. In Dhankuta, the RRC obtained further funding, developed strong upward and downward institutional links, and applied a ‘disaster risk reduction lens’ to existing local government responsibilities. In Panchkhal, RRC activities have been limited by funding and have focused on the strengthening of livelihoods. It may be concluded tentatively that community‐based disaster risk reduction activities are more successful when they are institutionally embedded in local government structures.     

Throughflow analysis: A stochastic approach

Ecological network analysis (ENA), predicated on systems theory and Leontiev input–output analysis, is a method widely used in ecology to reveal ecosystem properties. An important ecosystem property computed in ENA is throughflows, the amount of matter/energy leaving each compartment of the ecosystem. Throughflows are analyzed via a matrix representing their relationships to the driving input at the boundary. Network particle tracking (NPT) builds on ENA to offer a Lagrangian particle method that describes the activity of the ecosystem at the microscopic level. This paper introduces a Lagrangian throughflow analysis methodology using NPT and shows that the NPT throughflow matrix, , agrees with the conventional ENA throughflow matrix, , for ecosystems at steady-state with donor-controlled flows. The matrix is computed solely from the pathways (particles’ histories) generated by NPT simulations and its average over multiple runs of the algorithm with longer simulation time agrees with the Eulerian matrix (Law of Large Numbers). While the traditional NEA throughflow analysis is mostly used with steady-state ecosystem models, the Lagrangian throughflow analysis that we propose can be used with non-steady-state models and paves the way for the development of dynamic throughflow analysis.     

DOM对沉积物悬浮颗粒吸附铜的促进作用及机制

沉积物悬浮颗粒对重金属吸附是重金属在湖泊中迁移的关键环节,受到多种环境条件的影响.为了探究溶解性有机质（dissolved organic matter,DOM）对沉积物悬浮颗粒吸附Cu （Ⅱ）的影响及作用机制,通过室内模拟沉积物悬浮液进行Cu （Ⅱ）吸附试验.结果表明,两种DOM （富里酸和沉积物DOM）不同程度地促进了Cu （Ⅱ）在悬浮颗粒上的吸附;吸附48 h后,吸附百分比从71.51%分别提高到了75.31%和85.69%.扫描电子显微镜-能谱结果显示,在DOM的影响下,Cu （Ⅱ）被吸附后存在于沉积物颗粒内部.紫外-可见光谱技术分析结果表明,在吸附反应过程中,Cu （Ⅱ）与DOM存在先络合后解离的过程.荧光激发发射矩阵结合平行因子分析、同步荧光光谱结合二维相关分析的结果表明,类蛋白组分能够促进Cu （Ⅱ）在沉积物悬浮颗粒上的吸附,其中类酪氨酸组分在促进Cu （Ⅱ）被沉积物颗粒吸附沉淀过程中优先发挥作用,而类腐殖酸组分几乎没有促进吸附作用.完善了湖泊重金属迁移的相关理论,为沉积物重金属污染防治提供了一定的依据.
