对广东省流动人口婚育问题的初探

:广东是我国流动人口最多的省份,流动人口的婚育问题也成为研究的热点之一。本文首先对流动人口作了界定,并分析了广东流动人口的特征及其对婚育行为产生的正面和负面影响,这使计划生育管理面临巨大的压力。文章最后提出一些措施以图化解流动人口的婚育问题带给城市的压力     

陕西创建计划生育工作“综合服务县”有关理论问题的思考

本文结合陕西省提出和展开的“创建计划生育综合服务县”活动 ,讨论了“综合服务”的概念和背景。指出“综合服务县”是“综合服务”与“综合治理”的统一,是“三为主”、“三结合”的延伸,顺应了以人为中心的可持续发展潮流 ,标志着陕西计划生育工作进入新阶段     

劳务输出与脱贫致富

长期以来 ,有关方面均把贫困地区脱贫致富寄望于劳务输出。短期看来 ,劳务输出确能在一定程度上缓解贫困压力 ,但长期而言 ,劳务输出并不能从根本上解决贫困地区的脱贫致富问题。这是由劳力输出的限度、制约条件、实际效果及贫困的根本原因决定的。贫困地区脱贫的根本出路在于 :立足并开发贫困地区 ,走政府推进型脱贫致富之路。为此 ,当务之急须认真解决好三个问题 :( 1 )制定并实施开发贫困地区的战略 ;( 2 )国家加大对贫困地区的投入 ;( 3)地方政府真抓实干领导脱贫     

西方发达国家的就业促进经验及其对中国的启示

近年来 ,随着中国改革开放的深入开展 ,城镇失业率迅速上升。西方发达国家在就业领域 ,都曾经历了失业率上升的发展阶段。为降低失业率 ,各国采取了不尽相同但却切实有效的就业促进措施 ,积累了丰富的就业促进经验。中国也可以借鉴这些就业促进经验 ,以期逐步降低失业率     

民工城乡两栖型就业与城市化

本文从民工的城乡两栖型就业这个角度出发 ,重点分析了对现阶段城市化进程中民工城乡两栖型就业的特点 ,并对民工的城市化归宿问题作了一些探讨     

21世纪我国老年人口规模与老年人力资源开发

21世纪上半叶将是老年人口数量及老龄化突进的时期。老年人力资源是人力资源构成的重要组成部分 ,建立市场机制 ,把老年人愿为现代化建设作贡献的主观愿望和能力 ,与社会发展对老年人力资源的客观需要 ,合理、有效地结合 ,促进人口经济协调发展     

试论明朝在越南的统治

明朝在 140 6年 (永乐四年 )派兵占领越南 (安南 ) ,设置郡县 ,宣德二年 (142 7年 )撤出。在 2 0多年的统治中 ,明政府通过在政治、经济、军事、文化等各方面采取一系列措施来巩固在越南的统治。尽管这些措施曾经给越南人民带来了很大损失 ,但对稳定当时安南的社会秩序和发展生产 ,缓和阶级矛盾起到了重要作用。两国经贸往来和文化交流得到加强 ,也更加有助于两国人民之间的相互了解和增进双方的友谊。     

Theory Trimming

This paper attempts to show that the “Theory Trimming” technique makes little contribution to theory in sociology. A brief history of the technique is given, and several key assertions of its proponents are abstracted. These assertions are shown to be highly questionable. The general alternative to Theory Trimming is shown, and the relationship between Theory Trimming and more general orientations to research is discussed.     

Sex similarities in occupational status attainment: Are the results due to the restriction of the sample to employed women?

Research on sex differences in occupational attainment suggests that working men and working women attain essentially the same mean level of occupational attainment and do so through quite similar processes. A possible explanation for these similarities is that the sample of working women contains an overrepresentation of successful women, since women who can afford not to work will stay out of the labor force unless they find a job commensurate with their education. This we define as a censoring problem. By extending a technique developed by Heckman, we can estimate the structural parameters for all women, regardless of current employment status. This procedure allows us to assess the impact of the censoring problem on women's occupational attainment equations.     

Seasonal forcing on the dynamics ofClethrionomys rufocanus: Modeling geographic gradients in population dynamics

We interpret gradients in population dynamics of the gray-sided vole from the southwestern part of the island of Hokkaido to its northeastern part within the framework of a phenomenological model involving the relative length of summer and winter. In Hokkaido, as in other northern regions, both spring and fall is considered as short transition periods between the two main seasons — summer (the primary breeding season) and winter (the non-reproductive or secondary breeding season). We show that the geographic transition in dynamics may be understood as the combined consequence of different patterns of density-dependence during summer and winter, and geographically varying season lengths. Differences are shown to exist between summer and winter with respect to strength of density-dependence. Direct density-dependence, in particular, is stronger during winter than during summer. A model is presented to show how relative lengths of seasons can induce both stable and periodically fluctuating population dynamics. The results are compared and contrasted with what is otherwise known about the gradient in rodent dynamics in Fennoscandia.
