Household migration and the labor market position of married women

The present paper conceptualizes labor force participation among U.S. wives as both a determinant and consequence of household migration. A theoretical justification is provided for decomposing these relationships by occupational position of the wife. Applying log-linear models to data from the 1970 One-in-a-Thousand Public Use Sample, we corroborate previous research in that, on the average, the likelihood of interstate migration between 1965 and 1970 was greatest among families in which the wife was not employed prior to the move. However, among employed wives, those classified as professionals or managers were also found to accentuate the probability of household migration, particularly if the husband was not employed in 1965. The implication is that all types of employment by the wife need not limit family mobility as previous studies have suggested. Although migration was found to have a disrupting effect on the continuity of employment among most wives, this effect was most in evidence among wives employed in blue collar occupations. The data suggest the need for a careful reappraisal of traditional economic notions of migration, particularly as they apply to married women.     

不遇·玄思·宫怨·述行——简论屈骚影响下的汉代独创骚体赋

屈骚影响下的除悼骚体外的汉代骚体赋,具有很强的独创性质.在屈骚基础上,汉人拓展出多方面题材,建立起多种抒情模式,拥有各类经典,充分展示了汉人多彩多姿的人格风貌和杰出的创作才华,对后世同类文学有巨大影响.失志不遇类源于政治的不遇,寄托汉人愤世之情,揭示人生安顿策略;自广玄思类从批判社会的愤激进到"玄静"的人生至境;"宫怨"类写男女思恋,贴近人间性格;述行类拓展方域,弥补文学的北方缺憾.     

汉唐《论语》《孟子》学流变及特点

汉唐《论语》《孟子》学在不同时期呈现出不同的特点。汉代是《论语》、《孟子》学的发轫期,有关的注解之作已经涌现。魏晋南北朝时期《论语》学成果颇为丰富,但《孟子》却较少研究。同时,受时代学风影响,《论语》学的发展呈现出玄化或佛化的特点。唐代《论语》学的成就并不高,但是《孟子》其人其书的地位却不断提高,初步出现了所谓“孟子升格运动”。汉唐时期的《论语》《孟子》学的发展为宋代《四书》学的形成奠定了基础。     

教育评论的风格:实话实说

教育评论是根据社会发展和人的发展对教育提出的要求,对教育文化进行鉴别、评说,产生社会舆论作用,从而使教育在社会文明进步和人自身发展中发挥更大的作用。因此,教育评论要大力评论优良的教育文化,以向群众推荐优良教育文化为己任,但也要勇于批评不良的教育文化。依据教育规律对教育文化进行价值判断的教育评论本质,要求教育评论必须实话实说,但实话实说不是想说什么就说什么,想怎么说就怎么说,而是要切中社会主义教育文化的脉搏,分清是非,以马克思主义教育思想为指导,建设有中国特色的社会主义教育文化。     

对我国商品房价格的走势分析——以郑州市为个案

房价收入比的大小是影响房地产价格的关键，也是房地产是否出现拐点的判断依据。郑州市的数据分析显示，其商品房价格及房地产行业呈健康发展趋势，居民能够承受目前的住房压力，房地产行业与我国经济发展相适应。价格保持相对稳定是房地产业安全运行的关键，我国应该出台更具体的政策保持其健康发展。     

Penalized likelihood-ratio test for finite mixture models with multinomial observations

Due to the irregularity of finite mixture models, the commonly used likelihood-ratio statistics often have complicated limiting distributions. We propose to add a particular type of penalty function to the log-likelihood function. The resulting penalized likelihood-ratio statistics have simple limiting distributions when applied to finite mixture models with multinomial observations. The method is especially effective in addressing the problems discussed by Chernoff and Lander (1995). The theory developed and simulations conducted show that the penalized likelihood method can give very good results, better than the well-known C(α) procedure, for example. The paper does not, however, fully explore the choice of penalty function and weight. The full potential of the new procedure is to be explored in the future.     

用“嵌入-跳出法”控制高维耦合保守系统的混沌运动

推广了“嵌入-跳出法”对保守系统的混沌控制,将其应用到高维耦合保守系统——耦合标准映象中。数值模拟显示,该方法对于高维哈密顿系统的混沌行为控制非常有效。它能把系统的混沌轨道定位于KAM环面,并且具有一定的抗噪声能力。     

直接序列扩频信号PN序列盲估计方法

在非协作信息侦测情况下,提出了一种实用的直接序列扩频(DS-SS)通信信号PN码序列的快速盲估计方法。该方法根据DS-SS基带信号的特点,首先采用二阶循环统计量估计PN码周期,然后利用分段互相关平均估计PN码同步始点;并在准确预估计这2个参数的基础上,将接收信号以PN码周期分成多个时段,利用多重互相关方法估计PN码序列。理论分析与仿真表明,该方法在截获信号信噪比很低的情况下有很好的估计性能,且无需任何先验知识,对PN码码型也没有任何限制,是一种有效的快速盲估计方法。     

康集生态农场N素产投情况分析

本文采用投入产出法对农场的N素循环进行了分析。通过计算分析，得出本系统种植业的产投比为0．62，饲养业的产投比为0．48，系统产投比为0．40。说明系统N素的利用率较低。通过系统生产优势度和稳定性指数的计算发现：系统饲养业生产优势度大于种植业；系统稳定指数为0．34；森林覆盖率为18．6％．饲料转化率为20％。文中还指出了系统存在的主要问题。     

浅谈透视教学的改革新法
