项目总控的应用及其信息处理规划

随着国内大型建设项目的增多，大型建设项目的实施遇到诸多问题，其原因主要是业主对项目的控制能力不强，从而导致大型建设项目不能实现其质量、进度、投资等预期目标，甚至会导致整个项目的失败，项目总控模式的应用很大程度地解决了这一问题，另外，由于信息处理是项目总控的主要工作，因此，本也讨论了项目总控模式下的信息处理规划。     

GSM:技术标准化联盟的成功案例

GSM是欧洲第二代移动通信标准，它成功地成为在全世界占主导地位的移动通信标准。GSM的成功有两个方面的原因，一是欧盟的统一标准化政策；二是技术标准扩散过程中技术标准化联盟的形成。技术标准化联盟是当代信息技术发展中的一种较普遍现象。GSM是技术标准化联盟成功的一个典型案例。该案例引发了我们对技术标准化中的知识产权保护、技术标准化联盟以及技术创新等问题的深入思考，这些问题对于中国的电信业改革与发展具有重要的现实意义。     

双向沟通在绩效管理中的作用机制研究

绩效管理是企业将战略转化为行动的过程。绩效管理有别于传统的绩效考核，是一个完整的系统，具备完善的工作流程。绩效管理成败与否的关键在于管理者和员工之间双向沟通的过程，在于过程的连续性与有效性。本文分析了绩效管理各个环节中的沟通目的和作用机制以及就如何保证绩效管理中双向沟通的有效性提出了策略建议。     

The Impact of Basel II on Lending to Small- and Medium-Sized Firms: A Regulatory Policy Assessment Based on Spanish Credit Register Data

The objective of this paper is to evaluate the impact on bank credit exposures to small- and medium-sized Spanish firms of the current proposal for reform of the 1988 Capital Accord using information from the Spanish Credit Register. Capital requirements for exposures to those firms, according to the various revisions of the proposed capital reform (from the January 2001 consultative document to the April 2003 one), are calculated to analyze whether the existing pattern of bank financing of small- and medium-sized firms might be altered. Finally, the incentives for individual banks to adopt the advanced internal ratings-based approach proposed by Basel II are evaluated.     

Communicating risk for issues that involve ‘uncertainty bias’: what can the Israeli case of water fluoridation teach us?

Water fluoridation is a controversial issue in public health. Despite the uncertainty regarding its efficacy and safety, health officials continue to communicate it as ‘unequivocally’ safe and effective. Our focus is on how health officials and policy-makers in Israel frame the issue of water fluoridation in terms of certainty while promoting a mandatory fluoridation policy. According to van Asselt and Vos, the uncertainty paradox describes situations in which uncertainty is acknowledged, but the role of science is framed as providing certainty. Our study is an analysis of documents and media articles emphasizing the paradoxical language used by official representatives on the controversial topic of fluoridation. A central contribution of this study is that we coin the term ‘uncertainty bias,’ in which policy-makers do exactly what they accuse laypeople of doing, framing uncertainty in biased terms. We found that in order to establish mandatory regulation, health ministry officials expressed information in an unbalanced format, promoting the topic of fluoridation by framing it in exclusively positive terms. This study does not focus on the practice of water fluoridation per se, and is not intended to decide for or against it, but rather, to explore how the debate regarding it is communicated. Understanding this particular case can shed light on how other controversial topics are transformed into health policy that is characterized in equivocal terms.

辽宁省大学生亚健康现状及成因研究

以辽宁省6所不同类型院校的1 200名学生为研究对象,对他们的亚健康现状和影响因素进行了调查,可以看出我省大学生亚健康检出率略高于其他省份。影响辽宁省大学生亚健康症状的主要因素:对自身健康的关注度不够、饮食不规律、缺少合理的睡眠和适当的体育锻炼、闲暇时间睡懒觉及上网聊天打游戏;学校相关部门对学生身体状况的重视程度不够,缺少家人的影响与监督;大学生对未来前程的担忧和就业的压迫感、对自身工作能力的不自信。     

A probabilistic ghost in the experimental machine

This paper focuses on the opposition between two contemporary research programs in economics: behavioral economics (BE) and experimental market economics (EME). Our claim is that the arguments of this opposition can be clarified through the lens of another opposition in the philosophy of probability and in probability theory, between Bayesianism and frequentism. We show how this probabilistic opposition has indirectly shaped a controversy in psychology that opposes two research programs – Heuristics and Biases and Ecological Rationality – which play respective roles in the foundations of individual rationality in BE and EME. To understand these theoretical interrelationships, we investigate the 1996 controversy between Kahneman, Tversky, and Gigerenzer. Those psychologists held different views on how probabilistic representations influence the context-dependency of rationality. This provides a rationale to suggest that a probabilistic ghost may be haunting the experimental machine in economics, and explains how and why the oppositions between BE and EME are structured around the interplay between the norms of rationality and the context in which rationality is exercised.     

关于食品安全问题的几点思考
