买卖合同中的风险转移制度研究

在买卖合同中,风险应被限定为标的物因法定免责事由毁损、灭失的不利状态.由于各种风险的存在,风险转移制度显得尤为重要,它直接关系到当事人最根本的利益,因此是买卖合同中最重要的问题.各国对风险转移制度的规定是不同的,主要有合同订立主义、所有人主义及交付主义三种形式.我国买卖合同的风险转移制度采纳交付主义为一般原则,兼采特别法原则.

Statistics for weighing benefits and harms in a proposed genetic substudy of a randomized cancer prevention trial

Summary.  When evaluating potential interventions for cancer prevention, it is necessary to compare benefits and harms. With new study designs, new statistical approaches may be needed to facilitate this comparison. A case in point arose in a proposed genetic substudy of a randomized trial of tamoxifen versus placebo in asymptomatic women who were at high risk for breast cancer. Although the randomized trial showed that tamoxifen substantially reduced the risk of breast cancer, the harms from tamoxifen were serious and some were life threaten-ing. In hopes of finding a subset of women with inherited risk genes who derive greater bene-fits from tamoxifen, we proposed a nested case–control study to test some trial subjects for various genes and new statistical methods to extrapolate benefits and harms to the general population. An important design question is whether or not the study should target common low penetrance genes. Our calculations show that useful results are only likely with rare high penetrance genes.     

商业银行贷款风险及其防范

商业银行贷款风险是客观存在的一种经济现象。我国商业银行的不良贷款比率居高不下,状况令人堪忧。它严重影响了商业银行的经营,使其在日益激烈的竞争中处于不利的地位。商业银行为适应新协议的标准和日益激烈的竞争,必须加强贷款管理防范贷款风险。本文在商业银行贷款业务的基础上分析商业银行贷款风险形成的原因,提出商业银行贷款风险的防范对策。

利率变动下的存续期缺口管理和流量比例调整

在金融自由化和利率市场化的浪潮下,商业银行所面临的利率风险防范问题日益突出。利率风险管理成为商业银行经营管理中极其重要的环节。马考勒存续期缺口管理是现代西方商业银行的主要风险管理手段之一,合理构造存续期缺口可使商业银行净值不受市场利率影响,而流量比例调整可以克服存续期缺口受制于利率变动的不足,综合利用存续期缺口管理对我国商业银行建立风险管理机制起着重要的作用。     

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.
