论行为请求权案件执行标的及其强制执行措施

由于行为请求权执行案件执行标的的特性,需要施以特殊的执行措施。其中间接执行措施应当是一类基本的措施,替代履行应是可替代行为请求权案件优先采取的措施,迟延履行金则应当谨慎适用。而在细节上,任何一项执行措施的适用条件、启动程序、实施强度等都应有明确的、操作性强的配套规范,这样才能真正完善行为请求权执行案件的法律制度,维护司法权威。     

Humanitarian work psychology: The contributions of organizational psychology to poverty reduction

Achieving the MDG goal of reducing world poverty by 50% by 2015 requires the cooperative effort of many disciplines. To date the discipline of organizational psychology has not played as significant a role as it might in this endeavor. With the recent establishment of the Global Task Force for Humanitarian Work Psychology, this discipline signaled its commitment to the global effort. Organizational psychology offers to bring its expertise to poverty reduction: its ability to assess needs and capacity, develop partnerships with stakeholders, bring about and manage change, and systematically review, evaluate, monitor and revise high level mandates, policy development, program implementation and consultation on personnel issues. Its successes as practitioners-scientists in private enterprise will enhance its credibility for success in the public sphere. The article reviews the research and practice of some of the organizational psychologists presently engaged in poverty reduction and how humanitarian work psychology might enhance the efforts of anti-poverty organizations.

Social Movements and Rights Claims: The Case of Action Groups in the Niger Delta of Nigeria

This article examines how the various claims to, and demands for, rights have enabled and shaped the various equity and justice seeking social movements that have emerged in the Niger Delta of Nigeria, the key point being that claims to rights are fundamental of the logic and coherence of social movements. The article is divided into three sections. The first sets the conceptual and analytical frame by elaborating on the rights–social movements nexus. This is followed by a discussion of the historical and conceptual location of the Niger Delta. The rest of the article interrogates the contexts of relative deprivation, rights denial, and injustice within which social movements have emerged in the Niger Delta. A major objective is to account for why the social movements have been largely ethnic and most recently generational and to analyze the dynamics and outcomes of the rights struggles waged by the various social movements.

彩电业市场的竞争博弈与产业整合

近年我国彩电业发展迅速,在经历了几场价格战后,开始由数量扩张向市场集中转变。由价格战转向技术竞争是彩电市场竞争格局的必然趋势,市场正在进入一个以产品差异化为特征的技术竞争新阶段。市场格局和企业战略的变化加快了产品和产业升级,同时也必然引发新一轮的企业兼并和产业重整。加入WTO既是契机又是挑战,国产品牌借助彩电生产线成本较低、劳动力成本低廉、售后服务网点密集等比较优势,成功地占领了国内市场70％以上的份额;“洋彩电”采取“本地化”生产与合资、合作等跨国经营手段,积极加入到价格竞争行列。中国彩电市场正经历一场“国内市场上的国际竞争”。

人类交往有效性条件的转喻基础--语用学理论系列研究之五

哈贝马斯的普遍语用学理论设定了描述客观世界的真实性、在社会世界中建立人际关系的合理性和表达个人主观世界的真诚性三个交往有效性条件,这解决了传统哲学的经验论和先验论中主客二元对立的问题,但是没有论证交往有效性条件的基础。转喻理论可以解决这一问题,因为陈述型的语言使用所要求的真实性往往是基于指称式转喻的相对真实性的,表现型语言使用中的真诚性是以言语行为转喻为基础的,互动型语言使用中所要求的合理性则兼有述谓式转喻和言语行为转喻的基础。
