强制保险能否提高保险市场效率

文章以社会福利为衡量保险市场效率的标准,分析实施强制保险是否有助于保险市场效率的提高。文章首先证明了在信息不对称的保险市场中存在着市场失灵现象;然后通过比较实施强制保险前后社会福利的差异,得出结论:实施强制保险有助于社会福利的改善,从而可以提高保险市场效率。

大学合法性危机：大学治理的原因探究

现代社会对大学的自我合法性证明有两个核心要求：社会效能和学术自由，文章从社会效能和学术自由这两个方面的要求探究了大学治理产生的原因，并在此基础上得出大学合法性问题是一个由来已久的问题，大学合法性问题不仅体现在其因环境不同的变化性，还体现在其因遗传的不变性，大学治理是现代大学诉求其合法性的时代产物等结论。     

A powerful test for uniformity to detect highly peaked alternativedensities

A new class of statistical tests for uniformity based on sample ranges is proposed to detect a uniform density contaminated by a density with one or more high peaks. These kinds of alternatives occur quite frequently, especially in physics. It is shown that the proposed tests arc consistent and have high Pitman asymptotic relative efficiencies. Results of a Monte Carlo power study indicate that they, compared with other tests of uniformity, possess good power properties.A comparative study of various tests is also conducted using real data. An effcient algorithm for computing out test statistic and a table of percentage points are given, providing a practical guide for using the new test.     

城市生态绿化项目的政府投资方式改革——基于绿地建设与房产开发商的利益互动关系研究

通过对公共产品的内涵分析表明，仅由政府提供公共产品经常会出现不经济现象；只要解决外部性问题，公共产品是可以由私人提供的。以上海公共绿地为例，在分析目前公共绿地政府投资方式的基础上，研究绿地建设与房产开发商的利益互动关系，探讨城市绿地外部效应内部化的投资方式改革，提出房产与绿地联合开发建议，以期减轻政府建设城市绿地的资金压力，为实现城市公共绿地的最优投资提供理论上的依据。

Federated searching and usability testing: Building the perfect beast

With the ubiquity of federated search tools as viable solutions for students and researchers to search across external sources and internal repositories, users have become more sophisticated in their application of this technology. With the goal of optimizing the user experience of its newly introduced federated search offering, Endeavor Information Systems employed usability testing to gain insights into the critical requirements of librarians and information professionals for this solution. The results of this analysis, conducted in concert with market research and customer focus groups, and their relevance to Endeavor's federated search technology are the focus of this article.     

Estimation of a discriminant function from a mixture of two inverse Weibull distributions

The classification of a random variable based on a mixture can be meaningfully discussed only if the class of all finite mixtures is identifiable. In this paper, we find the maximum-likelihood estimates of the parameters of the mixture of two inverse Weibull distributions by using classified and unclassified observations. Next, we estimate the nonlinear discriminant function of the underlying model. Also, we calculate the total probabilities of misclassification as well as the percentage bias. In addition, we investigate the performance of all results through a series of simulation experiments by means of relative efficiencies. Finally, we analyse some simulated and real data sets through the findings of the paper.     

A Feminist Political Economic Critique of Women and Investment in the Popular Media

From a feminist political economic perspective, this paper examines the relationship between gender and investment in the popular media in three interrelating ways. First, a discourse analysis was used to examine eight popular books on investment for women published in the US. The popular financial literature asks women to solve the problems that they encounter in a patriarchal household by participating in the financial market. Second, Suze Orman was used as a case study to show the commodification process of financial information through the tactics brand differentiation, multi-platform delivery, and creation of niche markets. Third, the consumption of commodities is linked to that of production and distribution by revealing the relations between the gendered production and reproduction in the household, transnational corporations, and financial institutions.     

Decomposing the predictive performance of the moving average trading rule of technical analysis: the contribution of linear and non-linear dependencies in stock returns

The main purpose of this work is to decompose the predictive performance of the moving average (MA) trading rule and find out the portion that could be attributed to the possible exploitation of linear and non-linear dependencies in stock returns. Data from the General Index of the Athens Stock Exchange, from the Standard and Poor-500 Index of the New York Stock Exchange and from the Austrian Traded Index of the Vienna Stock Exchange are filtered by linear filters so as the resulting simulated ‘returns’ exhibit no serial correlation. Applying MA trading rules to both the original and the simulated indices and using a new statistical testing procedure that takes into account the sensitivity of the performance of the trading rule as a function of the length of the MA it is found that the predictive performance of the trading rule is clearly weakened when applied to the simulated indices indicating that a substantial part of the rule's predictive performance is due to the exploitation of linear dependencies in stock returns. This weakening is uneven; in general the shorter the MA length the more pronounced the attenuation.
