农民工子女留守原因分析

农民工子女留守农村是国家现行城乡分割的二元体制的结果,也是城乡两种不同社会与文明推拉合力作用的产物,同时是作为父母的农民工在迁移流动中的理性抉择与意识建构。城市生存境遇、乡村归属意识及城乡分割的义务教育体制等是农民工子女留守的重要因素。解决农民工子女问题,需要城乡相关体制的建立。     

清代流人的地理分布及其对文化发展的贡献——以吉林地区为视角

在以柳条边"封禁"和"军府制"管理机制为主导的诸多因素的综合作用之下,清代吉林地区流人的地理分布大体分为三个系统.这些流人吟诗著文、保卫边疆、开发土地、发展贸易,积极参与吉林的文化建设事业,与当地各民族一起为开发和建设吉林贡献了力量.流人在吉林的历史上应占有一席之地.     

养羊场户饲养规模扩大意愿影响因素分析——基于山东省17地市849家养羊场(户)的调查数据

养羊场(户)扩大饲养规模是提高羊养殖规模化程度的前提。利用山东省17地市849份养羊场(户)的调查数据,运用Logit二元离散选择模型,实证分析了养羊场(户)饲养规模扩大意愿的影响因素。研究结果表明:决策者文化程度、饲养规模、饲养类型、专业化程度、是否加入养羊合作社、是否加入产业化经营组织6个因素对养羊场(户)饲养规模扩大意愿有显著影响。     

Obtaining cancer risk factor prevalence estimates in small areas: combining data from two surveys

Summary.  Cancer surveillance research requires accurate estimates of risk factors at the small area level. These risk factors are often obtained from surveys such as the National Health Interview Survey (NHIS) or the Behavioral Risk Factors Surveillance System (BRFSS). The NHIS is a nationally representative, face-to-face survey with a high response rate; however, it cannot produce state or substate estimates of risk factor prevalence because the sample sizes are too small and small area identifiers are unavailable to the public. The BRFSS is a state level telephone survey that excludes non-telephone households and has a lower response rate, but it does provide reasonable sample sizes in all states and many counties and has publicly available small area identifiers (counties). We propose a novel extension of dual-frame estimation using propensity scores that allows the complementary strengths of each survey to compensate for the weakness of the other. We apply this method to obtain 1999–2000 county level estimates of adult male smoking prevalence and mammogram usage rates among females who were 40 years old and older. We consider evidence that these NHIS-adjusted estimates reduce the effects of selection bias and non-telephone coverage in the BRFSS. Data from the Current Population Survey Tobacco Use Supplement are also used to evaluate the performance of this approach. A hybrid estimator that selects one of the two estimators on the basis of the mean-square error is also considered.     

我国妇女围产期保健服务利用的影响因素

根据国家人口与计划生育委员会2001年全国计划生育/生殖健康调查资料,对我国城市、农村妇女围产期保健的现状进行比较研究.结果显示:城市妇女的围产期保健服务利用的总体水平高于农村;围产期保健利用的影响因素主要有妇女年龄、民族、文化程度、亲生子女数等;五期教育等宣传品的影响没有显著差别.     

非稳态下公共养老金资产负债表的编制与精算平衡调整

公共养老金资产负债表是国家资产负债表的重要组成部分,也是政府实施养老金改革的重要依据。已有研究给出了稳态下公共养老金资产负债表的编制方法,但这些方法无法直接用于非稳态情形。当前我国面临经济、人口、制度调整等非稳态环境,因此构建适应我国实际的非稳态下的公共养老金资产负债表成为重要的研究问题。非稳态下公共养老金资产负债表编制的主要难题在于缴费资产的计算。本文在梳理公共养老金资产负债表编制原理的基础上,推导出非稳态下缴费资产的计算公式,给出我国公共养老金资产负债表的编制方法和实际应用,并进一步测算分析了降低养老金待遇指数、延迟退休、提高缴费等多项改革对公共养老金资产负债表的影响。结果显示：我国公共养老金的资产负债平衡过度依赖财政补贴,无法实现缴费资产与负债的平衡。适当调整养老金待遇指数、退休年龄、缴费水平等参数,有助于恢复资产和负债的平衡,减轻制度对财政补贴的依赖。

Psychosocial work environment and mental health among travelling salespeople

Travelling salespeople have a rather unusual working environment, with long periods of absence from their firm and a low level of social contacts with colleagues. Furthermore, they are exposed to high demands in their work, which may conflict with a normal family life. In this paper a cross-sectional study of psychosocial work environment and mental health of Danish travelling salespeople is described. A sample of 1,306 travelling salespeople filled in a questionnaire (response rate 68%). The results indicate that poor mental health is associated with a number of demand indicators: number of working hours per week, number of customers per week, non-day work, and a high level of perceived job demands. On the other hand, the number of hours spent with customers per week is positively associated with mental health. The authors did not find the expected associations between poor mental health and several factors such as number of hours away from firm, nights away from home, and a low degree of perceived support from colleagues and superiors. It is concluded that the main stressors of travelling salespeople are long working hours, many customers, non-day work and high perceived psychological demands in general.     

知识整合的分析框架：评价、途径与要素

信息时代的知识创造速度在不断加快，知识整合逐渐成研究的热点。当前对于知识整合研究有一个重要缺失，就是还没有形成一个统一而系统的知识整合研究框架。本文基于现有的知识整合理论，以知识整合本身作为研究的核心，归纳和提炼出知识整合研究的三个层次，即评价层、途径层、要素层；通过对各层次所包含内容的深入分析，构建了知识整合研究的理论框架；并对该框架的理论和实践指导意义进行了讨论。
