失地农民权益保障的制度创新

农业用地转为建设用地是工业化和城市化进程中的必然现象.虽然我国政府对失地农民进行了补偿,但由于土地产权制度、土地征用制度以及社会保障制度的不完善,致使失地农民仍然蒙受着经济权益的损害、政治权益的剥夺和社会权益的缺失.因此,制度创新是保障失地农民权益的有效途径.应改革土地产权制度,明确集体土地所有权主体,健全农民承包经营权权能;完善土地征用制度,限定"公共利益"的范围,提高征地补偿标准,严格规范征地程序;建立健全失地农民的养老、医疗、最低生活保障制度和就业保障机制.     

论影响民族地区法治建设的因素——以四川凉山州彝族自治州为例

中华人民共和国是一个以汉族为主体,还有55个少数民族组成的统一的单一制国家。在少数民族聚居地方,实行民族区域自治,从而实现各民族团结、平等、进步和共同繁荣。依法治国方略,在西部民族地区仍然是实施该地区繁荣进步的基本策略。在西部大开发及加入WTO的大环境下,如何优化民族地区的发展环境,趋利避害,抓住机遇,发展经济,客观上也要求民族地区应有一个良好的法制环境。西部民族地区的法治建设,应充分考虑到各少数民族的历史、经济、人文、宗教、习惯等因素。     

“两伊问题”困扰中的美国海湾战略选择

伊战后,美国的海湾战略屡屡受挫,在中东面临危机多元化和扩散化的严重挑战。在伊拉克陷阱和伊朗核问题的双重困扰下,小布什政府及其后任可能的战略选择包括坚持原有“主导和预防行动”、采取“崩溃预防型”、恢复“稳定、威慑和遏制”、考虑“合作型秩序”等。但除非美国放弃独家主导海湾的霸权战略并调整其战略目标,否则难以在“支配”海湾地区和摆脱困境之间找到两全出路。     

中东地区国际体系的发展演变及其特点

本文在对中东地区国际体系的历史演变进行回顾的基础上,发现了两个重要特点:一是中东地区的民族国家体系并不是一个完全自足的体系,而是具有某种开放性,其发展演化的逻辑很大程度上受国际体系的影响和制约;二是由于长期的历史和文化联系的存在,中东地区的互动和交流特别频繁,使该地区的国际体系在一定程度上呈现出共同体的特征.     

绿色税收制度与我国循环经济发展

税收是解决资源和环境问题的重要政策工具。它可激励企业创新和应用先进技术减少资源消耗和污染物的排放。西方国家税制绿化改革为我国提供了值得借鉴的经验。我国应逐步完成费改税等改革并完善现有资源环保税收体系以促进我国循环经济的发展。     

Does IO Economics Really Make the Case for Investments in IT: A Rejoinder

The preceding critique [1] of the paper “The Information Problems in Organizations: A Research Model for the Value of Information and Information Systems” [3], reaches general conclusions with respect to the original paper and the applicability of economics to MIS research. These conclusions are based on arguments developed at a different level of analysis than that used in the original paper, and without considering the goals and intent of the original paper. The differences between the critique and the original paper are highlighted.

A Learning Curve Analysis of Expert System Use*

In this article, we study how an expert system affects novice problem solving in a financial risk analysis domain. We demonstrate that novice performance is improved after exposure to an expert system. Further, we show that novice performance continues to improve when the system is withdrawn. By comparing learning curves for people with exposure to those without, we can assess how much the system has benefitted its users. We demonstrate a quantitative methodology to measure the increment of learning due to the use of an information technology. We also explore the issue of how expertise is transferred from the system to the user.     

Auditors' Assessment of Management's Disposition: An Attributional Analysis*

Auditors' assessment of management's dispositions presumably affects their subsequent judgments. However, little is known about the process by which auditors infer characteristics of management. This paper proposes the theory of correspondent inferences [25] as a framework for examining auditors' assessment of management's dispositions; the model is tested in a laboratory experiment using experienced audit managers. The results are consistent with the proposed theoretical framework. Implications for future research are discussed.     

Marketing Communication Intensity Across Industries

Marketing communication intensity (i.e., the ratio of advertising and promotional expenditures to sales) has been an important topic for both business managers and academics. Here, we investigate cross-sectional and time-series variation of communication intensity due to: type of offering (product versus service) and type of market (consumer versus industrial). Overall, we find that both of these factors affect variation of communication intensity across industries and over time. However, the effect of market type is much more dramatic than the effect of offering type. Such knowledge about patterns in communication intensity levels helps managers make decisions about how much to spend on advertising and promotion.
