协商民主的限制简析

虽然协商民主号称是民主理论的“协商转向”。但是协商民主在理论和实践上都面临着诸多限制。协商民主强调以共同善为依据达成共识,但是共同善常常无法达到;协商民主强调以理性对话为主,但是参与者的理性能力是有限的,即使能够完全按照理性来进行协商,也未必能够保证公共利益最大化;协商民主主张由一般民众在公开、透明、平等的情况下进行讨论,但来自政治精英、经济优势阶级、专家学者、媒体的政治操弄始终无法避免。由于这些限制,协商民主无法替代代议民主,它的价值在于培养公民的共和精神和包容、参与、平等的政治文化。

碎纸片的拼接复原

碎片文件的拼接是一种结合计算机技术和人工辅助进行资料复原的过程。通过对碎片文件的外形轮廓、颜色变化以及所包含内容的格式等特征进行分析,可以利用计算机技术进行相应的自动拼接工作,从而有效提高拼接效率。本文提出了一种基于碎纸片的外形轮廓和内容格式相似性的拼接算法,将相似度高的碎纸片进行计算机辅助的自动拼接,同时在必要情况下辅以人工干预的手段,从而实现快速有效复原数据的目的。实验结果证明我们提出的方法具有很高的效率和正确性。     

On the Efficiency of Bankruptcy Law: Empirical Evidence in Spain

The current economic crisis is showing one of the main problems that many companies in financial distress have to face, namely, the impact of bankruptcy law in relation to companies and firms. This paper aims to analyze the bankruptcy law ex‐ante efficiency when companies are in financial distress. To test it out, two research questions are submitted: (i) Is solvency, the criterion used in the Spanish law, the best one to assess the relative significance of the main indicators, which determine bankrupt firms? (ii) Is the Spanish bankruptcy law efficient according to solvency or are there better criteria? To answer them, a logistic regression model is conducted. The sample embraces 1,387 firms in Spain, the data being obtained from 12 Commercial Justice Courts complemented with financial information. The main conclusion is that the solvency criterion is adequate to classify bankrupt companies although currently Spanish Bankruptcy law is not as efficient as it could be. Additionally, the relevant companies' indicators, which explain the financial distress procedure, are presented. Copyright © 2013 INSOL International and John Wiley & Sons, Ltd     

Selection of a Representative Value Function for Robust Ordinal Regression in Group Decision Making

In this paper, we introduce the concept of a representative value function in a group decision context. We extend recently proposed methods UTA^GMS-GROUP and UTADIS^GMS-GROUP with selection of a compromise and collective preference model which aggregates preferences of several decision makers (DMs) and represents all instances of preference models compatible with preference information elicited from DMs. The representative value function is built on results of robust ordinal regression, so its representativeness can be interpreted in terms of robustness concern. We propose a few procedures designed for multiple criteria ranking, choice, and sorting problems. The use of these procedures is conditioned by both satisfying different degrees of consistency of the preference information provided by all DMs, as well as by some properties of particular decision making situations. The representative value function is intended to help the DMs to understand the robust results, and to provide them with a compromise result in case of conflict between the DMs.     

粮食需求预测方法述评

在国内外24篇有代表性的粮食需求预测文献基础上,文章重点对这些文献的预测时间、预测结果、预测方法、预测的地区、城乡和品种差异进行了比较分析.现有文献的3个主要特点是:首先,定性分析、时间序列模型和联立方程模型是最常见的三种方法,单方程模型和其他方法应用较少;第二,文献集中关注2010 ～2030的粮食需求预测,且在相同时间点不同文献的预测结果比较接近;第三,在预测中,少数文献关注地区差异、城乡差异或品种差异,并且同时关注3种差异的只有1篇.在对现有文献评价基础上,文章提出粮食需求预测领域应进一步深入研究的方向.

卓越工程师教育培养计划是我国工程教育改革的切入点和突破口,对促进工程教育回归工程,提高人才培养质量具有重要的作用。文章以韩国的KAIST大学和国立首尔大学等的工程实践教育课程建设、过程实施、教育理念为例,分析了国外大学高等工程教育的主要特征,提出了在我国实施卓越工程师教育培养计划的几点建议。     

基于价格折扣的物流服务供应链协调模型研究

在一个物流服务集成商与一个物流服务提供商及一个客户构成的物流服务供应链中,文章建立了各个利益主体的利润模型及物流服务供应链的整体利润模型,并分别求解了其最优解,通过对模型的分析和求解,得出各个利益主体与整体供应链的最优解存在矛盾。为了协调这个利益矛盾,提出了利用价格折扣契约来对物流服务供应链进行协调,并计算得出价格折扣系数的取值范围,最后给出了算例以证明这种契约对物流服务供应链的协调具有有效性。
