行政事业单位完善内部控制的探讨

内部控制理论是现代管理理论的重要组成部分。我国内部控制规范的制定和实施起步较晚,目前还缺乏一套对行政事业单位行之有效的内部控制指导性规范。随着事业单位体制改革的推进,建立完善高效的内部控制制度变得更加迫切。通过分析行政事业单位内部控制存在的问题,列举了实施内部控制的七项措施,为这类单位内部控制制度的建立提供参考。

三点渐进式无模成形分析与数值模拟

渐进成形是一种金属板材快速无模成形方法。工具头挤压板材产生连续的局部变形,通过累积局部变形以达到整体成形。然而每一局部变形必然影响整体变形,所以对局部变形的控制就成为成形精度的关键。文章提出一种3点渐进式无模成形方法,可以很好的控制的局部变形。通过LS-DYNA模拟整个成形过程,并通过分析节点在成形过程中的位移变化,可以看出此方法对局部变形的控制效果,提高了成形精度。     

水下现浇模袋混凝土施工质量控制

在某预制场造船基地改造工程中,船舶下水滑道采用了水下现浇模袋混凝土的施工工艺。船舶下水方式为气囊滚动式下水。为保证船舶顺利下水,滑道的坡度及平整度是工程施工的控制重点。在以往的工程中,水下现浇模袋混凝土主要应用于护坡工程,对坡度及平整度的要求低于船舶下水滑道。针对水下现浇模袋混凝土和船舶下水滑道的特点,此工程在基床整平、模袋加工、模袋铺设和混凝土工程等方面进行了严格的施工质量控制,对施工细节进行了把握,取得了良好的效果。

高校学生党员质量控制问题

高校一些大学生要求思想政治进步,积极靠近党组织,志愿加入中国共产党,成为一名光荣的中共党员。由于大学生是一个特殊的青年群体,为党内输入新鲜血液而增加党的生机与活力,对于完成伟大的社会主义事业和共产主义事业的意义是不可估量的。但是,在确定他们入党、准予入党和入党后始终能够达到一个党员的标准,在工作中先锋模范、努力拼搏、无私奉献,关键的是他们有很强的党员意识、很高的思想政治觉悟。为此,提出学生党员质量控制和如何控制的问题,从入党前注重对入党积极分子的培养、入党中严格入党条件和程序、入党后追踪培养与严格管理三个相互联系的过程中提出质量控制问题。     

供应商专项投资与感知的合作风险:关系发展阶段与控制机制的调节作用研究

本文从供应商———制造商关系发展这一动态的角度探讨供应商专项投资与其感知合作风险之间的关系以及契约和关系规范的不同调节作用.通过对中国家电行业261对供应商与制造商的关系的问卷调查,采用因子分析和多元回归的方法对概念模型及假设进行验证.本文研究结果表明:(1)在不同的关系发展阶段供应商专项投资与其感知的合作风险有着显著的差异.(2)尽管契约和关系规范对供应商专项投资与其感知的合作风险间的正向关系有着负向调节作用,但在关系发展的不同阶段,这种调节作用也存在着显著的差异.本文对于认识和了解关系发展阶段中供应商专项投资带来的合作风险感知水平的变化以及两种不同控制机制调节作用的差异性具有重要的理论和现实意义.     

Burnout and impaired cognitive functioning: The role of executive control in the performance of cognitive tasks

Abstract

Burnout patients often report deficits in cognitive control, and there is a need to understand the processes involved. Drawing on recent findings, we hypothesized that emotional exhaustion and task-related demands on executive control would interact in predicting performance in tasks requiring the updating and monitoring of working memory as well as the inhibition of prepotent (dominant or automatic) responses. In accordance with recent conceptualizations of burnout, we focused on emotional exhaustion as the core symptom of burnout. The sample comprised 81 employees recruited from nursing homes for elderly care in Germany, who participated in a laboratory study involving cognitive tasks. Based on a median split, participants were divided into two groups: those with high burnout and those with low burnout. In line with our hypotheses, the high exhaustion participants performed less well than those with low exhaustion only when tasks put high demands on their executive control. As predicted, high levels of emotional exhaustion were associated with more errors and longer reaction times when demands on executive control were high, whereas no performance differences were found when both tasks put low demands on executive control. The implications for practice are discussed.     

An EOQ model with partial delayed payment and partial backordering

In many transactions concerning selling and buying, a specified delay of payment is offered or accepted by the seller. This can be regarded as a kind of discount and has potential consequences for the order size. These kinds of effects are not explicitly incorporated in the classical formulas for economic order quantities (EOQ). In this research we consider an EOQ problem under partial delayed payment. A fraction of the purchasing cost must be paid at the beginning of the period and the remaining amount can be paid later. Shortages are permitted and occur as a combination of backorders and lost sales. The aim of this paper is to determine the order and shortage quantities.     

The effect of objective job demands on registered sickness absence spells; do personal,social and job-related resources act as moderators?

Abstract

This study applied Karaseks demand-control model, using sense of coherence (SOC), social support and job control as moderators of effects of job demands on ensuing sickness absence spells in a 3-year follow-up of 856 municipal employees. Among men the results supported the active learning hypothesis. Passive jobs predicted a high number of sickness absence spells and active jobs predicted a low number of spells. for short spells (1-3 days), the demand-control interaction, however, depended on SOC. In active jobs SOC was negatively associated with sickness absence spells; in passive jobs no such association was found. For long spells (3 days), the demand-control interaction depended on occupational level; active jobs were predictive of low absence spells among blue collar men. Among women, the results supported the strain hypothesis. The demand-control interaction, however, depended on household size. In small households, high-strain jobs predicted a high number of spells, while no increase in spells was found in active versus low-strain jobs. In larger households, the number of spells correlated positively with increasing demands even when control was good. The demand-control interaction, however, depended on SOC and spouse support. With strong SOC or spouse support, absence spells in active jobs remained on a relatively low level, otherwise active jobs led to a high number of spells. This suggests that SOC and spouse support may act as protective factors against female role conflicts associated with active jobs
