高中化学竞赛培训的总体规划

国际化学奥林匹克竞赛已经成为国际瞩目的化学资优青年学生一展聪明才智的最高竞技舞台。在我国,化学奥林匹克竞赛也日益受到重视,已逐渐成为衡量一个学校、一个教师工作成绩的重要指标。为了使高中化学竞赛培训工作更具针对性和系统性,本文从目标的定位、培训的模式、选手的选拔和培训内容的设计四个方面对高中化学竞赛培训进行了总体规划,力求为高中化学竞赛培训起到抛砖引玉、提纲挈领的作用。     

E‐Procurement Infusion and Operational Process Impacts in MRO Procurement: Complementary or Substitutive Effects?

The procurement of maintenance, repair, and operating (MRO) goods has remained a relatively understudied topic in the literature. Though vital cost efficiencies can be extracted from procurement processes through investments in e‐procurement systems, there is little empirical work that addresses how such systems should be deployed within organizations. In this study, we focus on the role of e‐procurement systems in MRO procurement and study two critical aspects of infusion. The first dimension captures the depth of e‐procurement use within the procurement function, while the second dimension depicts the breadth of use. We argue that these two dimensions of e‐procurement use, and their interaction, will be related to the performance of the MRO procurement process. Using survey data from 193 service organizations and structural equation modeling techniques, we show that the two infusion dimensions are significantly associated with improved process performance. Additionally, we show a substantial substitutive effect between the two use dimensions on performance. Our work has significant implications for managers who seek to gain efficiencies by the deployment of Internet‐based technologies within operational processes. Our conceptualization of e‐procurement infusion along two dimensions provides a more fine‐grained analysis of performance benefits accruing from the infusion of information technologies within organizations.     

关于违法行政行为之争讼撤销的几个问题

通过争讼程序撤消违法行政行为是实现违法行政责任的重要形式。争讼撤销的基本特征在于必须以当事人的申请为前提。对我国法律所规定的争讼撤销申请人资格条件应当作宽泛的理解 ,凡是其合法权益受到行政行为侵犯的人 ,都应被赋予申请争讼撤销的资格。我国目前争讼撤销的事项范围过于狭窄 ,需要逐步扩大。争讼撤销的申请期限应当本着对当事人有利的原则进行调整     

论社会主义新农村建设中的农村法文化重构

在当前的社会转型期,各种因素之间的相互博弈使原有的农村法文化出现了明显的失范现象,并直接导致了一系列农村社会问题的生发.农村法文化建设是新农村建设的重要组成部分.以文化承载力、文化发展力和文化张力为理论基础,对农村法文化进行重构将在新农村建设中凸显出重要的社会作用.     

土地投资强度的理论与实证研究

针对目前我国某些产业投资新建项目由于土地投资强度不够,未能充分实现“规模效应”,甚至造成了资源闲置等现象,科学地提出了土地投资强度的计算公式,并对我国经济技术开发区的土地投资强度进行了实证研究。确定了该计算方法的有效性。它可以用来指导产业用地的集约管理工作,从而更好地实现对土地资源的有效控制。

关于使用价值量几个问题的辨析

传统政治经济学认为使用价值量等同于物品数量,物品数量是影响使用价值量的惟一因素。事实上,把使用价值量定义为“某种使用价值满足人的需要的程度”的认识是更加科学的。衡量使用价值量大小的标准是人的需要的满足程度而不是物品数量;使用价值量的影响因素不是单一的而是多样的,既有客观因素又有主观因素;由于人的需要的满足程度是一个动态标准,所以物品的使用价值量是不能够精确计量的。

经理报酬激励强度的综合评价研究

旨在建立一个运用多维度定量指标判断经理报酬激励强度的评价方法,有利于全面认识各上市公司经理报酬的激励程度。根据评价结果把经理报酬激励强度分为激励不足、适中、过度,并实证研究不同激励强度上市公司治理结构的特征,进而提出改进经理报酬激励公平和效率的有效手段,提高对不同类型企业高管薪酬管理的针对性。     

Rational choice and the political bases of changing Israeli counterinsurgency strategy

Israeli counterinsurgency doctrine holds that the persistent use of credible threat and disproportionate military force results in repeated victories that eventually teach the enemy the futility of aggression. The doctrine thus endorses classical rational choice theory's claim that narrow cost-benefit calculations shape fixed action rationales. This paper assesses whether Israel's strategic practice reflects its counterinsurgency doctrine by exploring the historical record and the association between Israeli and Palestinian deaths due to low-intensity warfare. In contrast to the expectations of classical rational choice theory, the evidence suggests that institutional, cultural and historical forces routinely override simple cost-benefit calculations. Changing domestic and international circumstances periodically cause revisions in counterinsurgency strategy. Credible threat and disproportionate military force lack the predicted long-term effect.
