Implementing cash for work programmes in post-tsunami Aceh: experiences and lessons learned

Cash for work (CFW) programmes are utilised in various disaster and emergency contexts and were a prominent component of the tsunami response in Aceh province, Indonesia. This paper describes Mercy Corps' CFW programme, discusses CFW implementation experiences and provides key recommendations for similar programmes in future emergencies. For the majority of CFW participants and their households, CFW was the only source of household income and 93 per cent of household incomes were attributable to it. The CFW programme empowered displaced populations to return to their communities; 91 per cent of participants indicated that CFW facilitated their return. Other reported psychosocial benefits included providing productive activities and giving communities an opportunity to work together. Mercy Corps' experience in Aceh demonstrates that cash disbursements can be safely delivered in a widespread manner in emergencies, and that when implemented on a short-term basis, can have positive impacts at the individual and community level.     

安全生产规划体系框架探讨

阐述了建立安全生产规划体系的必要性,探讨了安全生产规划的定义、研究对象、目的和内容,指出安全生产规划是为使安全生产与经济社会协调发展而预先对未来一段时间内各项安全生产工作所做的时间和空间的合理安排,具有整体性、综合性、动态性、前瞻性、信息密集和政策性强等特征。同时设计了"四级、三层"的安全生产规划体系,即在行政层级上分为国家级、省级、市级和县级四个层级,在协调作用上分为宏观指导层、项目布局层和方案实施层三个层次。国家安全生产规划从宏观上对全国安全生产工作做出谋划与部署,省级安全生产规划要接受国家安全生产规划宏观指导性的引导和要求,并结合各地实际进行项目布局,同时借助专项规划分解内容,制定市、县级规划实施方案。     

煤炭企业安全生产管制多方博弈研究

为研究我国煤矿企业安全生产管制效果影响因素和管制力度相对不足的问题,构建中央政府、地方政府、煤矿企业和煤矿员工四方博弈模型。模型分析结果表明:地方政府对煤炭企业的监管效果受到企业预期损失、安全生产管理成本和中央政府给予举报者的奖金额的影响。从而,可以得出结论:大多数中小煤矿企业有其自发管理的动力,地方政府监管力度较低;企业需要改进管理方法,降低管理成本,合理制定员工事故赔偿额标准,降低员工的遵守规章的难度,并适度提高对员工遵守规章行为的奖励力度,以降低员工从事不安全生产行为的概率。     

轮班制度对于地铁司机疲劳的影响

立足于轮班工作模式,阐述轮班制度对司机疲劳产生与积累的影响。介绍疲劳指数方法和池田公式的理论基础及模型构架,基于北京地铁13号线现行轮班表,分别应用上述两种研究方法进行地铁轮班司机疲劳程度的分析。两种方法的评估结果显著相关,均说明13号线现行轮班表的制定会导致司机疲劳的产生,存在安全运营风险。应用上述方法可实现对司机疲劳程度的非接触式测量,避免对司机驾驶作业的干扰,同时为地铁运营公司的安全管理人员制定合理的轮班方案,建立全面、量化的动态管理措施,提高行车安全保障提供了科学依据。     

企业安全生产管理责任矩阵应用

在全面分析安全生产责任矩阵的基础上,进一步提出针对落实企业安全生产主体责任的企业安全生产管理责任矩阵新方法。围绕企业安全生产责任管理,彻底分解企业安全生产管理任务,明确划分企业安全生产管理个人和部门的角色,并按照每一项安全生产任务有且只有一个角色、每一个角色至少参与一项安全管理任务的准则,建立一般类型的中小企业安全生产管理责任矩阵,将企业安全生产责任管理有序清晰地体现在一个责任矩阵中,使企业安全生产主体责任管理权有所属、事有所任、责有所归。这对指导和落实企业安全生产主体责任具有一定的参考作用和借鉴意义。     

企业安全生产主体责任绩效评估建模与应用

在全面分析企业安全生产主体责任内涵的基础上,采用问卷调查、访谈等多种手段,从企业依法生产经营、组织机构与人员配置、安全教育培训、员工权益维护、规章制度管理、作业场所管理及事故管理等方面建立系统的企业安全生产主体责任绩效评估指标体系;结合层次分析法和变权综合理论,构建企业安全生产主体责任绩效评估模型,并进行实例应用。结果表明:依法生产经营是对进行安全生产主体责任绩效评估的前提,机构与人员设置、作业场所安全、规章制度、安全教育培训、事故管理、员工权益维护等子体系对落实企业安全生产主体责任的重要性程度依次递减,所构建的企业安全生产主体责任绩效评估方法和模型是有效的。     

When the going gets tough: Employee reactions to large-scale organizational change and the role of employee Machiavellianism

Large-scale, long-term change initiatives take time to unfold, which can be a source of uncertainty and strain. Investigating the initial 19 months of a large-scale change, we argue that during these stages, employees' change-related beliefs become more negative over time, which negatively affects their work engagement and, ultimately, increases their turnover intentions. Furthermore, we investigate the impact of a trait, Machiavellianism, on change reactions and propose that employees high in Machiavellianism react more negatively during change processes as they are especially susceptible to uncertainty and stress. We test our (cross-level) moderated mediation model in a three-wave longitudinal study among employees undergoing a large-scale change (T1: n = 1,602; T2: n = 1,113; T3: n = 759). We find that employees' beliefs about the impact and value of the change are indeed negatively related to change duration and that decreases in these perceptions come with a decline in engagement and increases in turnover intentions. Moreover, employees high in Machiavellianism react more strongly to a deterioration in change-related beliefs, showing stronger reductions in engagement and stronger increases in turnover intentions than employees low in Machiavellianism. Our study offers explanations for the negative effects of large-scale changes including an explanatory factor for disparate employee reactions to change over time.     

高职“订单式”培养模式实施路径——以市场营销专业为例

以人才市场需求为导向,建立“订单式”人才培养模式是高职院校彻底解决学生就业的理想培养模式。但目前国内很多院校在实施过程中存在着企业积极性不高、实习实践专业指导师资力量不足、缺乏特定的实践场所等种种问题。在建立“订单式”培养模式过程中,很多院校先从与企业签订“订单”着手,这给本身不愿意接收不具备任何实践经验学生的企业带来较重的负担,增加了完全实现“订单”式培养的难度。主要结合国内实际情况,以市场营销专业为例,论述高职院校应该从调研市场专业人才需求出发,首先调整自身培养方案,主动迎合企业需求,最终真正实现“订单式”培养模式的路径。     

Pulsed pumping process optimization using a potential flow model

A computational model is applied to the optimization of pulsed pumping systems for efficient in situ remediation of groundwater contaminants. In the pulsed pumping mode of operation, periodic rather than continuous pumping is used. During the pump-off or trapping phase, natural gradient flow transports contaminated groundwater into a treatment zone surrounding a line of injection and extraction wells that transect the contaminant plume. Prior to breakthrough of the contaminated water from the treatment zone, the wells are activated and the pump-on or treatment phase ensues, wherein extracted water is augmented to stimulate pollutant degradation and recirculated for a sufficient period of time to achieve mandated levels of contaminant removal. An important design consideration in pulsed pumping groundwater remediation systems is the pumping schedule adopted to best minimize operational costs for the well grid while still satisfying treatment requirements. Using an analytic two-dimensional potential flow model, optimal pumping frequencies and pumping event durations have been investigated for a set of model aquifer-well systems with different well spacings and well-line lengths, and varying aquifer physical properties. The results for homogeneous systems with greater than five wells and moderate to high pumping rates are reduced to a single, dimensionless correlation. Results for heterogeneous systems are presented graphically in terms of dimensionless parameters to serve as an efficient tool for initial design and selection of the pumping regimen best suited for pulsed pumping operation for a particular well configuration and extraction rate. In the absence of significant retardation or degradation during the pump-off phase, average pumping rates for pulsed operation were found to be greater than the continuous pumping rate required to prevent contaminant breakthrough.
