论大理洞经文化的特点及社会功能

洞经音乐文化是中华文化的一部分,大理洞经音乐文化源远流长,它是道、佛、儒、唐宋词牌和民间小调的集合体,是以道教思想为基础发展演变而成的音乐社团和民俗文化,有大理地域文化的特色,是多元文化的结晶。洞经文化具有积淀历史文化、凝聚民众社团、陶冶民众道德情操的功能。目前应当抓好对洞经文化的继承与发展的课题。     

论人事保证的制度功能及我国的立法选择——兼评《劳动合同法》第9条

《劳动合同法》第9条在现有立法禁止劳动合同物的担保的基础上，进一步否定了人的担保，与很多国家以及我国台湾地区立法上的规定不同。从社会学和经济学的视角分析了人事保证制度的基本功能，客观评价了既存人事保证制度，在此基础上提出我国立法对现有人事保证制度不应该全盘否定，而应该扬弃，重新界定人事保证的内涵。     

A bayesian estimator for the dependence function of a bivariate extreme‐value distribution

Any continuous bivariate distribution can be expressed in terms of its margins and a unique copula. In the case of extreme‐value distributions, the copula is characterized by a dependence function while each margin depends on three parameters. The authors propose a Bayesian approach for the simultaneous estimation of the dependence function and the parameters defining the margins. They describe a nonparametric model for the dependence function and a reversible jump Markov chain Monte Carlo algorithm for the computation of the Bayesian estimator. They show through simulations that their estimator has a smaller mean integrated squared error than classical nonparametric estimators, especially in small samples. They illustrate their approach on a hydrological data set.

外语戏剧节对英语专业学生的影响——以四川大学外国语学院2005年戏剧节为例

在加德纳的多元化智能理论指导下,从学生个性发展、教材层面、教师授课角度、学生语言接受能力等方面对外语戏剧节对学生的影响进行观察性描述,通过抽样调查,可以得出结论:外语戏剧节对英语专业学生的间接影响主要体现在提高学习自信心、增强学习动机上;戏剧节对英语专业学生的直接影响,更多表现在对班级文化和身份的积极建塑上.     

货币政策调控有效性的实证检验

应用平稳性检验、协整性检验与因果检验,分析货币政策对经济政策与物价变动的影响,以此检验货币政策的有效性。实证结果表明,金融变量与经济增长、物价变动之间存在着长期稳定的因果关系,特别是80年代以来推行的市场经济改革,增强了中央银行选择货币供应量作为中介指标的可操作性,中央银行可通过控制货币供给总量来影响宏观经济活动,达到间接调控的目的。     

Some results on optimality in models with heteroscedastic errors from partial optimum designs

This paper studies optimum designs for linear models when the errors are heteroscedastic. Sufficient conditions are given in order to obtainD-, A- andE-optimum designs for a complete regression model from partial optimum designs for some sub-parameters. A result about optimality for a complete model from the optimality for the submodels is included. Supported by Junta de Andalucía, research group FQM244.     

轻声的作用与语音修饰

作为一种重要的语音现象，仅从可区别词义及词性来解释轻声的存在因由是不能令人信服的。轻声在语流中的语音修饰作用所带给我们的审美感受使得它的存在有理有据。     

大学英语语调交际功能的课堂教学研究与实践

大学英语课堂教学不能只注意学生英语语音，更重要的是在语音的基础上掌握语调及其功能。从学生语言运用能力的角度来说语调的教学比纯语音教学应该更重要，因为同一个单词或句子用不同的语调在同等交际背景下传递出的含义就会不同，有时还会是相反的含义。以语调的交际功能为出发点，运用语用学的相关理论，设计并分析了基于语调交际功能的英语课堂教学模式的实践，探讨了这种模式的可行性和有效性，以引起大家对语调教学的重新思考。     

Bootstrap Estimation of Benchmark Doses and Confidence Limits with Clustered Quantal Data

The benchmark dose (BMD) is an exposure level that would induce a small risk increase (BMR level) above the background. The BMD approach to deriving a reference dose for risk assessment of noncancer effects is advantageous in that the estimate of BMD is not restricted to experimental doses and utilizes most available dose-response information. To quantify statistical uncertainty of a BMD estimate, we often calculate and report its lower confidence limit (i.e., BMDL), and may even consider it as a more conservative alternative to BMD itself. Computation of BMDL may involve normal confidence limits to BMD in conjunction with the delta method. Therefore, factors, such as small sample size and nonlinearity in model parameters, can affect the performance of the delta method BMDL, and alternative methods are useful. In this article, we propose a bootstrap method to estimate BMDL utilizing a scheme that consists of a resampling of residuals after model fitting and a one-step formula for parameter estimation. We illustrate the method with clustered binary data from developmental toxicity experiments. Our analysis shows that with moderately elevated dose-response data, the distribution of BMD estimator tends to be left-skewed and bootstrap BMDL s are smaller than the delta method BMDL s on average, hence quantifying risk more conservatively. Statistically, the bootstrap BMDL quantifies the uncertainty of the true BMD more honestly than the delta method BMDL as its coverage probability is closer to the nominal level than that of delta method BMDL. We find that BMD and BMDL estimates are generally insensitive to model choices provided that the models fit the data comparably well near the region of BMD. Our analysis also suggests that, in the presence of a significant and moderately strong dose-response relationship, the developmental toxicity experiments under the standard protocol support dose-response assessment at 5% BMR for BMD and 95% confidence level for BMDL.
