从主权国家的兴衰看权力博弈形态的转型

传统的国际关系理论,无论是现实主义、自由主义、建构主义还是科学行为主义理论,都是把主权国家抽象成一个统一的国际关系行为体。这一行为主体有一致的利益,也自然要有一致的对外政策目标和手段。在20世纪,尤其是在两次世界大战和冷战期间,这一概念抽象是非常准确的。但冷战结束以后,尤其是进入21世纪以后,这一概念抽象逐渐与国际关系的现实相违背。一方面,国家综合实力并不能直接转化为具体领域的竞争优势;另一方面,很多国家,包括超级大国在内,其对外政策的主要阻力可能不是所谓的竞争对手,而是其国内不同的利益集团。这导致传统的国际关系理论,从假设到概念和推理层面,都已经无法解释和预测今天的世界,而权力小博弈理论可以为认识多元复杂互动博弈时代的国际关系提供一个新的解释框架。     

Statistical testing strategies for assessing treatment efficacy and marker accuracy in phase III trials

When a candidate predictive marker is available, but evidence on its predictive ability is not sufficiently reliable, all‐comers trials with marker stratification are frequently conducted. We propose a framework for planning and evaluating prospective testing strategies in confirmatory, phase III marker‐stratified clinical trials based on a natural assumption on heterogeneity of treatment effects across marker‐defined subpopulations, where weak rather than strong control is permitted for multiple population tests. For phase III marker‐stratified trials, it is expected that treatment efficacy is established in a particular patient population, possibly in a marker‐defined subpopulation, and that the marker accuracy is assessed when the marker is used to restrict the indication or labelling of the treatment to a marker‐based subpopulation, ie, assessment of the clinical validity of the marker. In this paper, we develop statistical testing strategies based on criteria that are explicitly designated to the marker assessment, including those examining treatment effects in marker‐negative patients. As existing and developed statistical testing strategies can assert treatment efficacy for either the overall patient population or the marker‐positive subpopulation, we also develop criteria for evaluating the operating characteristics of the statistical testing strategies based on the probabilities of asserting treatment efficacy across marker subpopulations. Numerical evaluations to compare the statistical testing strategies based on the developed criteria are provided.

学术论文一稿多投的"诊"与"治"

一稿多投是学术界由来已久且难以医治的顽症。究其原因,主要是科研压力之下作者的投机心态、作者投稿经验的匮乏、稿件时效性的压力以及网上投稿的便捷与低成本等因素使然。一稿多投会造成编方人力资源的浪费,容易引发一稿多发,挤占宝贵的版面资源,引起版权纠纷,破坏学术诚信,扰乱科研秩序。要从加强制度建设、加大惩罚力度、利用高科技进行防范、健全监督机制、加强学术道德教育、提高编辑效率等方面,把"他律"与"自律"结合起来,惩防并举,标本兼治,多管齐下,齐抓共管,从根本上规范科研活动,根治一稿多投顽症。     

The impact of social power and influence on the implementation of innovation strategies: A case study of a UK mega infrastructure construction project

Influence plays a key role in reaching consensus among multiple actors involved in project-based decision-making processes. While prior literature devotes considerable attention to describing influence, little attention has been paid to influence at the individual level of the strategic project manager within the context of megaprojects. This research intended to fill this knowledge gap by identifying and describing the influence strategies that a strategic project manager applies when implementing innovation strategies on megaprojects. A qualitative case study was used to examine the complex social processes involved in a major UK capital investment programme. The findings underline a critical subset of influence strategies, notably higher-management support, inspirational appeal and bargaining. The study proposes a utilitarian structure of social power comprising selective, supportive and executory power bases.     

制约权力必须依靠制度——对邓小平政治体制改革理论的思考

权力需要制约。邓小平不主张照搬西方那套权力制约体制,但他十分赞成对权力进行制约,猛烈抨击滥用权力造成的种种弊端。制约权力不能靠人治,道德自律和纵向权力制约固然有一定的作用,但关键要靠制度。要建立和健全一系列制约权力的获得、权力的行使、权力运行后果的制度,在党内外自下而上逐步推行选举制,建立群众不信任票达一定比例必须引咎辞职的制度,建立弹劾罢免制度以及严格的任期制,切实执行重大过错责任追究制,保证人民赋予的权力服务于人民。     

马原小说语言试验背后的话语权力意识

马原小说以先锋姿态与陌生化叙事引人注目,而背后涌动的却是作家获取话语权力的欲望以及为实现欲望而进行的语言实验与狂欢。当这种实验与狂欢模糊了公共权力的视野,失却了对现实境遇的本真显现,成为作家主观欲望的肆意表演,则注定会走向失语与沉寂。
