英语专业“专转本”学生英语学习调查及启示

采用问卷调查和语言测试的方法,对英语专业“专转本”学生的英语学习背景和学习状况进行描述性调查与研究,并基于对所得数据的统计和分析,建议教师根据学生的实际水平,在教材的使用、教学内容和教学手段等方面作相应的调整,抓好专科与本科教学的衔接。     

永久随机数在多层次调查中的应用

采用永久随机数法抽样技术抽到的样本具有很好地样本兼容的性质。本文讨论了采用序贯srswor抽样技术和Poisson抽样技术这两种永久随机数法抽样技术时,多层次调查的实现问题,希望能为多层次调查的实现提供一点启示。     

ESTIMATING DISTRIBUTION FUNCTIONS FROM SURVEY DATA WITH LIMITED BENCHMARK INFORMATION

The model-based approach to estimation of finite population distribution functions introduced in Chambers & Dunstan (1986) is extended to the case where only summary information is available for the auxiliary size variable. Monte Carlo results indicate that this ‘limited information’ extension is almost as efficient as the ‘full information’ method proposed in the above reference. These results also indicate that the model-based confidence intervals generated by either of these methods have superior coverage properties to more conventional design-based confidence intervals.     

A bias analysis of Weibull models under heaped data

Retrospectively collected duration data are often reported incorrectly. An important type of such an error is heaping—respondents tend to round-off or round-up the data according to some rule of thumb. For two special cases of the Weibull model we study the behaviour of the ‘naive estimators’, which simply ignore the measurement error due to heaping, and derive closed expressions for the asymptotic bias. These results give a formal justification of empirical evidence and simulation-based findings reported in the literature. Additionally, situations where a remarkable bias has to be expected can be identified, and an exact bias correction can be performed.

学生视野:高校大课堂教学中值得注意的几个问题

采用无记名方式对实施学分制的本科生大课堂教学现状作了调查。调查结果显示大课堂教学中存在着诸如讲授方法、教学媒介、逃课现象以及学生主体地位缺失等问题,并就此进行了深入、多层面的分析,希望引起相关部门的重视,使学生在学分制改革中普遍受益。     

近年来毛泽东民主政治思想研究综述

毛泽东民主政治思想是目前学术界关注的重大课题,学界近年来对这一课题进行了较全面的研究,大体来说,学界的研究主要围绕以下几方面进行：对毛泽东民主政治思想的主要内容进行概括；对毛泽东民主政治思想的重大论题进行分析；对毛泽东民主政治思想与社会主义政治文明的关系进行探讨；对毛泽东、邓小平的民主政治思想进行比较；对毛泽东晚年民主政治思想及其实践失误原因进行探析。学者的研究成果显著,但仍存在较大的研究空间。     

目前中国网络调查的局限性和适用范围

网络调查的逐渐兴起和蓬勃发展,使人大有传统调查过时之感,也有人认为网络调查将很快取代传统的数据收集方法。但网络调查毕竟是一种新生事物,其方法的科学性如何?结果的有效性、准确性怎样?实践中有哪些新的理论问题需要探讨?等等,目前还没有一套完整的理论加以阐述。本文拟就     

Survey nonresponse and the distribution of income

The paper examines the distributional implications of selective compliance in sample surveys, whereby households with different incomes are not equally likely to participate. Poverty and inequality measurement implications are discussed for monotonically decreasing and inverted-U compliance-income relationships. We demonstrate that the latent income effect on the probability of compliance can be estimated from information on response rates across geographic areas. On implementing the method on the Current Population Survey for the U.S. we find that the compliance probability falls monotonically as income rises. Correcting for nonresponse appreciably increases mean income and inequality, but has only a small impact on poverty incidence up to poverty lines common in the U.S. Martin Ravallion: Corresponding author.
