突发重大疫情网络舆论的生成逻辑､演进特征与治理机制

新形势下突发重大疫情网络舆论不仅给疫情防控带来了严峻挑战，而且给维护国家意识形态安全带来了较大压力。厘清网络舆论的生成逻辑，把握网络舆论发展的演进特征，对做好网络舆论引导与谣言治理意义重大。在现代网络社会，随着交往实践的普遍进行，从现实逻辑、实践逻辑与理论逻辑来看，突发重大疫情网络舆论的生成，是网络议题、网络交往和网络传播相互作用的结果。受网络社会交往实践主体、客体、环体和介体等多种因素影响，突发重大疫情网络舆论又呈现为非线性的发展演进趋势，极易引发“蝴蝶效应”造成舆论秩序失范，甚至导致“塔西佗陷阱”的舆论信任危机，给疫情防控带来复杂变数。必须建立健全网络舆论治理机制，有效管控舆情，提高疫情防控治理水平。     

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。     

浙江省新生代农民工继续教育状况研究

中共中央、国务院印发的《新时期产业工人队伍建设改革方案》提出,要帮助"新生代农民工增加受教育培训机会,提高专业技能和胜任岗位能力",并将教育作为促进农民工融入城市,成为稳定就业的产业工人的重要路径。以浙江省11个地级市的服务行业、建筑行业、制造业的从业人员为主要调查对象,了解浙江省新生代农民工接受继续教育的现状与特点,发现新生代农民工存在自身接受继续教育的动力意愿不足、企业进行职业技能培训投资的动力意愿不足等问题,并据此提出要做好终身教育宣传、搭建继续教育平台、优化在职培训模式等解决办法。     

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.     

司法附属行政语境下的中国古代法官地位

“司法附属行政”是中国古代司法的一个重要特征。在这一背景下，中国古代法官地位就呈现出鲜明的附属性特征，这种特征同样体现在法院的地位和司法权的地位上，这也导致中国古代法官没有专门的职业保障制度，而这一切都深深地镶嵌在当时的人治大背景之中。通过与现代法官地位的比较，可以更加深切地感受到古今法官地位以至整个司法状况的巨大差异。中国现代法官地位在独立性方面相对于古代法官有了巨大改善，但仍然不尽如人意，还需要在今后的司法改革中进行反思和重点关注。     

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.     

现代中国自由主义知识分子的 "叙拉古情结"——以胡适为中心

作为现代史上涉足政治最深的自由主义知识分子, "爱惜羽毛" 的胡适难掩其对政治的浓厚兴趣, 他的政治野心屡受打击, 却百折不挠. "四一二事变" 后, 在客居上海的三年半时间里, 胡适与政治权力之间历经从疏离、 接近、 受挫再到反抗、 放弃和妥协的心路历程. 胡适在上海期间与国民党的话语权冲突, 源于其逼仄的生存空间以及欧美宪政理念与军事强人政治的分歧, 体现了自由主义知识分子对精神自由和人格独立的追求, 是 "叙拉古" 母题下 "知识分子遇到政治" 的典型样本.     

Politics and Scientific Expertise: Scientists, Risk Perception, and Nuclear Waste Policy

To study the homogeneity and influences on scientists'perspectives of environmental risks, we have examined similarities and differences in risk perceptions, particularly regarding nuclear wastes, and policy preferences among 1011 scientists and engineers. We found significant differences ( p 0.05)in the patterns of beliefs among scientists from different fields of research. In contrast to physicists, chemists, and engineers, life scientists tend to: (a)perceive the greatest risks from nuclear energy and nuclear waste management; (b)perceive higher levels of overall environmental risk; (c)strongly oppose imposing risks on unconsenting individuals; and (d)prefer stronger requirements for environmental management. On some issues related to priorities among public problems and calls for government action, there are significant variations among life scientists or physical scientists. We also found that–independently of field of research–perceptions of risk and its correlates are significantly associated with the type of institution in which the scientist is employed. Scientists in universities or state and local governments tend to see the risks of nuclear energy and wastes as greater than scientists who work as business consultants, for federal organizations, or for private research laboratories. Significant differences also are found in priority given to environmental risks, the perceived proximity of environmental disaster, willingness to impose risks on an unconsenting population, and the necessity of accepting risks and sacrifices.     

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。
