On the mode of administering a questionnaire and responses to open-ended items

Concurrently administered personal and telephone surveys are compared to measure differences between the modes for identical questions. Speed of questioning is found to be greater in telephone interviews than personal interviews. The faster pace of telephone interviews is linked to shorter answers to open-ended items on the telephone. The tendency to reduce such responses is disproportionately exhibited by younger, affluent respondents who tend to provide detailed responses in personal interviews.     

Binary Dynamic Logit for Correlated Ordinal: estimation,application and simulation

We evaluate the estimation performance of the Binary Dynamic Logit model for correlated ordinal variables (BDLCO model), and compare it to GEE and Ordinal Logistic Regression performance in terms of bias and Mean Absolute Percentage Error (MAPE) via Monte Carlo simulation. Our results indicate that when the proportional-odds assumption does not hold, the proposed BDLCO method is superior to existing models in estimating correlated ordinal data. Moreover, this method is flexible in terms of modeling dependence and allows unequal slopes for each category, and can be used to estimate an apple bloom data set where the proportional-odds assumption is violated. We also provide a function in R to implement BDLCO.

被征地农民就业与参保意愿及政策建议——基于西安市调查的分析

通过问卷调研,对被征地农民的就业与参加社会保障的现状、意愿及其影响因素进行研究。首先,被征地农民的就业率低主要原因是缺乏市场竞争意识,就业意愿与就业能力有偏差。其次,政策宣传力度不够和被征地农民社会保障制度存在缺陷,是被征地农民参保意愿低的主要原因。除此之外,征地补偿标准不合理、被征地农民市民化程度低,是造成被征地农民"弱势"地位的深层次原因。对此,应根据被征地农民的需求,建立多种形式的就业培训和就业扶助,尤其扶持有意向的被征地农民自主创业;为实现与城镇社会保障的对接,应建立多层次的被征地农民社会保障体系。     

家庭托育点管理实践及启示：政策工具的视角

家庭托育点的规范化对婴幼儿健康成长至关重要。通过文献收集和访谈获得既往管理举措和当前试点政策,运用政策工具进行分析和总结,探究管理家庭托育点的背景、对象和措施。结果表明：家庭托育点因经济优势而被纳入管理,现有征求意见稿管理对象偏向小规模邻托,但试点和市场偏向较大收托规模;消防审查依托既有消防验收,师资准入要求偏低,质量监管依靠政府。管理建议：应根据收托规模区分小型和大型家庭托育点开展试点;完善三方协同的管理架构,设定专门空间环境要求,提高师资准入要求,建立综合质量监管。     

李白卒年新论

李白的卒年,依据李阳冰、范传正所记的李白生年和李华所记的李白享年即可确定为大历元年。从曾巩到王琦,对此提出了异议。但他们所提出的依据没有一条是信实可靠的,包括他们认作铁证的《为宋中丞自荐表》,编在至德二载也是不可靠的。要正确地确定李白的卒年,还是要回到李阳冰、范传正和李华那里去。     

19世纪末20世纪初中国商人阶层的崛起

在漫长的中国封建社会中,商业被贬之日末务,商人也位于四民之末,士农工商的地位归序似乎成了中国封建社会亘古不变的模式.然而到了19世纪末20世纪初,随着民族危机日益加深,商战呼之欲出,商人团体相继成立,商会诞生,商人政治意识提高并且对政治广泛参与,使商人的社会地位发生了根本性的变化.商人阶层坚持不懈地努力终于迎来了清政府自上而下的重商措施的出台.清延设立商部以指导商人组织,制定商律以规范商人行动,颁行一系列工商的法规以奖商恤商,一系列新经济政策的实施使社会舆论开始从抑商转为誉商,商人在社会上广受赞扬,官员也开始纷纷投资经商.所有这些,促进了中国新的绅商阶层的形成,并进而带动了整个商人阶层随之崛起.

Measuring non-linear dependence for two random variables distributed along a curve

We propose new dependence measures for two real random variables not necessarily linearly related. Covariance and linear correlation are expressed in terms of principal components and are generalized for variables distributed along a curve. Properties of these measures are discussed. The new measures are estimated using principal curves and are computed for simulated and real data sets. Finally, we present several statistical applications for the new dependence measures.
