论唯物史观的三大基本特征

唯物史观具有三大基本特征, 即: 实践原则与主体性原则的内在一致, 它为唯物史观奠定了彻底的唯物主义理论基础; 历史发展过程的客体制约性与主体创造性的辩证统一, 它为唯物史观赋予了辩证的理论品格; 人的自由解放与历史进程的高度一致, 它使唯物史观获得了明确的价值指向。这三大基本特征有着内在的逻辑联系, 使唯物史观与其它一切历史观从根本上区别开来。     

高职教育课程教学体系改革的实践探索

近年来在政府的扶持下,高职教育得到了大力的发展,现已成为高等教育的半壁江山。高职教育在现代社会发展、教师教育和教师专业化发展要求下则需要对现行的课程教学体系进行深层次的分析和改革,力求培养目标和规格符合人才发展要求,以为社会培养出大批优秀的具有应用型和实践性的高级技术人才。这一做法也同样适用其他高职类院校,具有很强的借鉴意义。

Empirical likelihood confidence intervals for the mean of a population containing many zero values

If a population contains many zero values and the sample size is not very large, the traditional normal approximation‐based confidence intervals for the population mean may have poor coverage probabilities. This problem is substantially reduced by constructing parametric likelihood ratio intervals when an appropriate mixture model can be found. In the context of survey sampling, however, there is a general preference for making minimal assumptions about the population under study. The authors have therefore investigated the coverage properties of nonparametric empirical likelihood confidence intervals for the population mean. They show that under a variety of hypothetical populations, these intervals often outperformed parametric likelihood intervals by having more balanced coverage rates and larger lower bounds. The authors illustrate their methodology using data from the Canadian Labour Force Survey for the year 2000.     

Simple detection of outlying short time series

Sets of relatively short time series arise in many situations. One aspect of their analysis may be the detection of outlying series. We examine the performance of standard normal outlier tests applied to the means, or to simple functions of the means, of AR(1) series, not necessarily of equal lengths. Although unequal lengths of series implies that the means have unequal variances, that are only known approximately, it is shown that nominal significance levels hold good under most circumstances. Thus a standard outlier test can usefully be applied, avoiding the complication of estimating the time series' parameters. The test's power is affected by unequal lengths, being higher when the slippage occurs in one of the longer series     

Inference for the measurement of poverty in the presence of a stochastic weighting variable

Empirical applications of poverty measurement often have to deal with a stochastic weighting variable such as household size. Within the framework of a bivariate distribution function defined over income and weight, I derive the limiting distributions of the decomposable poverty measures and of the ordinates of stochastic dominance curves. The poverty line is allowed to depend on the income distribution. It is shown how the results can be used to test hypotheses concerning changes in poverty. The inference procedures are briefly illustrated using Belgian data. An erratum to this article can be found at     

Randomized response techniques for complex survey designs

Singh et al. ([13]) pointed out that the Randomized response (RR) technique proposed by Moors ([9]) is not desirable because it fails to protect the confidentiality of the respondents and they provided two alternative strategies free from the above drawback but limited to SRSWOR sampling only. In this paper, generalization of one of the strategies is provided for complex survey designs, wider class of estimators and for quantitative characteristics. Relative efficiency of the modified strategy is tested through empirical investigations. An erratum to this article is available at .
