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

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。     

模糊学与模糊美学的现状与未来

作为观察世界的基本方法之一 ,模糊学是针对事物的模糊性而产生的。它和精确方法并不冲突 ,而是各自都有自己的范围。从某种角度上说 ,模糊方法是精确方法的沿伸和补充。受模糊学方法启发而产生的模糊美学 ,不但对于美学 ,对其它人文社会科学无疑也有十分积极的影响 ,因为它出现的本身就具有不可忽视的方法论意义。作为一门新学科、自然还需要不断完善 ,还需要多种学科的通力协作     

A two phases queueing system with Bernoulli vacation schedule under multiple vacation policy

This paper deals with a single server Poisson arrival queue with two phases of heterogeneous service along with a Bernoulli schedule vacation model, where after two successive phases service the server either goes for a vacation with probability p (0≤p≤1) or may continue to serve the next unit, if any, with probability q(=1−p). Further the concept of multiple vacation policy is also introduced here. We obtained the queue size distributions at a departure epoch and at a random epoch, Laplace Stieltjes Transform of the waiting time distribution and busy period distribution along with some mean performance measures. Finally we discuss some statistical inference related issues.     

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.
