论庭前证据交换制度

证据交换制度作为民事诉讼的一项重要制度有其自身的发展历程,从而显示了其重要的意义,并得到了各国的重视。我国也建立了民事诉讼证据交换制度,但仍存在着很多缺陷,所以有必要对我国的民事诉讼证据交换制度进行完善。     

A theoretical basis for perturbation methods

In this paper we discuss a new theoretical basis for perturbation methods. In developing this new theoretical basis, we define the ideal measures of data utility and disclosure risk. Maximum data utility is achieved when the statistical characteristics of the perturbed data are the same as that of the original data. Disclosure risk is minimized if providing users with microdata access does not result in any additional information. We show that when the perturbed values of the confidential variables are generated as independent realizations from the distribution of the confidential variables conditioned on the non-confidential variables, they satisfy the data utility and disclosure risk requirements. We also discuss the relationship between the theoretical basis and some commonly used methods for generating perturbed values of confidential numerical variables.     

论公司法上的自我交易

对于自我交易,各国公司立法确立了比较完备的实体规规和相应有效的救济程序,而我国现行的《公司法》只是在第61条第2款作了原则性的禁止规定,缺乏可操作性。鉴于现有立法之不足,通过对各国关于自我交易规定的比较研究,试图确立符合法理的实体和程序规则,使得我国公司法上的自我交易问题得到有效解决。     

论改进我国企业环境信息报告

我国企业环境信息报告存在的问题是报告目标单一,内容不完整,模式不规范。在可持续发展战略条件下,企业既要向政府主管部门提供环境信息报告,也应向投资者、债权人、社会公众等提供企业环境影响信息。因此,有必要改进企业环境信息报告。主要措施包括:培养和提高信息使用者的环境意识,开展可持续发展教育;健全法制环境,加大环境监管力度;发挥会计职业界的作用,鼓励会计师事务所开展环境信息审计业务。     

Model Diagnostics for Remote Access Regression Servers

To protect public-use microdata, one approach is not to allow users access to the microdata. Instead, users submit analyses to a remote computer that reports back basic output from the fitted model, such as coefficients and standard errors. To be most useful, this remote server also should provide some way for users to check the fit of their models, without disclosing actual data values. This paper discusses regression diagnostics for remote servers. The proposal is to release synthetic diagnostics—i.e. simulated values of residuals and dependent and independent variables–constructed to mimic the relationships among the real-data residuals and independent variables. Using simulations, it is shown that the proposed synthetic diagnostics can reveal model inadequacies without substantial increase in the risk of disclosures. This approach also can be used to develop remote server diagnostics for generalized linear models.

Ordinal utility models of decision making under uncertainty

This paper studies two models of rational behavior under uncertainty whose predictions are invariant under ordinal transformations of utility. The quantile utility model assumes that the agent maximizes some quantile of the distribution of utility. The utility mass model assumes maximization of the probability of obtaining an outcome whose utility is higher than some fixed critical value. Both models satisfy weak stochastic dominance. Lexicographic refinements satisfy strong dominance.The study of these utility models suggests a significant generalization of traditional ideas of riskiness and risk preference. We define one action to be riskier than another if the utility distribution of the latter crosses that of the former from below. The single crossing property is equivalent to a minmax spread of a random variable. With relative risk defined by the single crossing criterion, the risk preference of a quantile utility maximizer increases with the utility distribution quantile that he maximizes. The risk preference of a utility mass maximizer increases with his critical utility value.     

Priority Setting for the Distribution of Localized Hazard Protection

We address the problem of distributing safety-enhancing devices across a region, where each identical device provides for only local protection of the population. The devices protect nonidentical sectors of the population. The sectors of population are exposed to nonidentical intensities of hazard. A method for the screening and prioritizing of needs for the protective devices is described. An approach of risk-benefit-cost analysis under uncertainty is recommended as follows. Measures of hazard intensity and population exposure are identified. Exogenous parameters that influence assessments of risks, benefits, and costs are identified. Uncertainties of the exogenous parameters are propagated by interval analysis. Several tiers of the plausibility of need for protection are identified. The tiers are useful in setting priorities for the distribution of the safety devices. The method is demonstrated in an engineering application to roadway lighting, but has implications for disaster preparedness, anti-terrorism, transportation safety, and other arenas of public safety.

癌症基因组研究信息披露的伦理探讨

癌症基因组计划是当前研究热点,存在诸多伦理、法律及社会问题,如何有效地保障基因组研究参与者的知情同意是值得关注的内容。信息披露(disclosure)作为知情同意的第一要素具备深厚的伦理基础,然而与传统医学研究相比,癌症基因组研究由于其目的与内容的特殊性,研究中信息披露的内容和标准尚存在诸多伦理问题,需要深入探讨。
