《国际私法》课程的教学方法探讨

案例教学和差异比较法教学是适合《国际私法》课程特点的教学方式方法。其中 ,案例教学是将教学内容、教学目的和教学方法等融汇于特定的案例分析和评价的一种教学过程和教学组织架构 ,一般由案例的准备、呈现、问题、思与行、评价和回归教材 6个环节动态地建构而成 ;而差异比较法教学则是以一个特定的国家的法律为比较基准 ,通过对各被比较国家在同一问题上的法律规定作相应的对比和分析 ,找出相应的差异并进一步探索国际私法的基本原理和解决法律冲突的方法的一种教学过程和教学方法 ,一般包括准备、实体法上的差异比较、法律冲突、解决冲突的方案、冲突规范的比较、综合评价 6个步骤。教师在《国际私法》课程的教学过程中应精心设计和实施案例教学和差异比较法教学且应将二者结合运用     

Mapping water quality by local scoring

The mean density of bacteria in a water body is commonly monitored using quantal assay. This paper describes the use of local scoring in estimating the spatial distribution of mean density from quantal assay results at a set of point locations. An application to estimating the mean density of fecal conform bacteria in a coastal pond is presented. Model diagnostics based on a parametric bootstrap are also presented.     

Modelling map positional error to infer true feature location

The authors consider the issue of map positional error, or the difference between location as represented in a spatial database (i.e., a map) and the corresponding unobservable true location. They propose a fully model‐based approach that incorporates aspects of the map registration process commonly performed by users of geographic informations systems, including rubber‐sheeting. They explain how estimates of positional error can be obtained, hence estimates of true location. They show that with multiple maps of varying accuracy along with ground truthing data, suitable model averaging offers a strategy for using all of the maps to learn about true location.

Pseudo–Modelling of Outliers for Estimation of Regression And Time Series Models

This paper documents situations where the variance inflation model for outliers has undesirable properties. The model is commonly used to accommodate outliers in a Bayesian analysis of regression and time series models. The alternative approach provided here does not suffer from these undesirable properties but gives inferences similar to those of the variance inflation model when this is appropriate. It can be used with regression, time series, and regression with correlated errors in a unified way, and adheres to the scientific principle that inference should be based on the data after obvious outliers have been discarded. Only one parameter is required for outliers; it is interpretable as the a priori willingness to remove observations from the analysis.     

Defining the linear portion of a sigmoid‐shaped curve: bend points

Formulae are provided that define the ‘bend points’, the beginning and end of the essentially linear dose–response region, for the four‐parameter logistic model. The formulae are expressed in both response and dose units. The derivation of the formulae is shown in order to illustrate the general nature of the methodology. Examples are given that describe how the formulae may be used while planning and conducting bioassays. Copyright © 2003 John Wiley & Sons, Ltd.     

证交所国债买断式回购交易的风险研究

国债买断式回购的推出衍生了抛补套利、循环融券卖空、债券组合交易、买断式回购组合交易这几种新的主要交易模式,丰富了投资者的交易手段,然而,这些新的交易模式将容易引发做空风险、流动性风险和更大的信用风险,在分析这些风险的基础上,提出了建立健全保证金制度、信用评估制度以及制定严格的交易规则等风险防范对策。     

略论毛泽东的语言风格

语言风格体现一定的审美观,毛泽东的语言风格体现了他独有的审美取向和审美价值。这里通过对毛泽东生活实践和写作实践中所形成的伟人风采的展示和文风、语言风格的研究,将毛泽东的语言风格概括为通俗平易,形象生动;理中寓情,情理交融;想象丰富,气势磅礴;古为今用,推陈出新,为人们树立了语言艺术运用的光辉典范。
