蒙古语近音近义词刍议

以往对蒙古语近义词的研究 ,只从词义之间的关系出发 ,重点放在解释近义词的意义差别上 ,却很少涉及它的形式结构。虽然蒙古语绝大多数近义词的语音形式相互间毫无关系 ,但是 ,有些近义词的构成 ,具有一定的语音学和形态学基础。通过语音手段构成的近义词是由同一词分化而产生 ;通过形态手段构成的近义词是由同根词派生出来的

Social Stratification and the Division of Household Labor in Japan: The Effect of Wives' Work on the Division of Labor among Dual-earner Families

Abstract:  This article explores the relationship between social stratification and the division of household labor by examining how the contribution to housework by husbands in dual-earner families varies across the Japanese social stratification structure. First, I review previous studies concerning the determinants of husbands' participation in housework and construct four hypotheses regarding the relative resources explanation, the time constraints explanation, the ideology/sex role explanation, and the alternative manpower explanation. Second, I examine the empirical support for these hypotheses in dual-earner couples and the effect of social stratification on husband's participation in housework, which has not been studied thus far. Third, I investigate the effect of social stratification in more detail. According to the results of TOBIT regressions and other supplementary analyses, the principal findings are as follows:

• 1) 

  the relative resources explanation is not supported;

       

基于并行遗传算法的去相关多用户检测器

通过将码分多址通信系统中的最佳多用户检测视为组合优化问题,利用遗传算法能全局寻优的优势,提出了一种基于并行遗传算法的去相关多用户检测器。理论分析和仿真表明:该多用户检测器无论是抗多址干扰的能力还是抗远近效应的能力都明显优于传统的检测器和去相关多用户检测器;由于采用了基于“联姻”策略的并行遗传算法,使这种多用户检测器更易于实时应用和硬件实现。     

关于中世文学开端的一点想法

中国文学史有关上古、中世、近世的分期法 ,早先是通过明治时代日本的中介影响 ,借鉴了西方历史的划分标准。这套标准本身有其特定的构架及内涵 ,故在今天采用上述分期法时 ,仍应考虑到与它的对应性。从我国早期文学的表现形态来看 ,至秦汉 ,文学的发展受专制独裁政体及思想统制的压抑 ,丧失了先秦文学中曾出现的相对比较自由的精神与批判意识 ,质性上显示出较明显的异面 ,并对后世有着深远的影响。比照欧洲中世纪文学的情形 ,笔者赞同以秦汉作为中国中世文学的开端     

Premarital Cohabitation and Housework: Couples in Cross‐National Perspective

The authors examine the effect of premarital cohabitation on the division of household labor in 22 countries. First, women do more routine housework than men in all countries. Second, married couples that cohabited before marriage have a more equal division of housework. Third, national cohabitation rates have equalizing effects on couples regardless of their own cohabitation experience. However, the influence of cohabitation rates is only observed in countries with higher levels of overall gender equality. The authors conclude that the trend toward increasing cohabitation may be part of a broader social trend toward a more egalitarian division of housework.     

20世纪中国文学思潮进程现象反观(一)

每一个时代都有自己时代所需要的历史叙述与文学观念 ,成为了学术的基本权力。 2 0世纪中国文学已经走完了它的全程 ,并完整地展现在我们的记忆与案头。纵览 2 0世纪中国社会思潮的史学进程 :从“人文主义精神”到“社会主义思潮” ,再向世纪末“现代主义理念”的嬗变演进 ,决定 2 0世纪中国文学思潮的整体走向 ,传统的“现、当代文学史”的分期理论与编史叙述的本质缺陷 ,清晰地暴露出来 ,从而有力地支撑着“2 0世纪中国文学”编史叙述的基本构想。     

世界文化视野中的楚美术

楚美术是我国上古时期具有南方文化品格的艺术事象。作为上古时期楚人奇异而丰富的美术创造 ,它以其卓尔不群的创造姿态和原始浪漫主义精神开创了世界上古美学的新视界。本文试图将这一重要美术现象放在上古世界文化视野中去观照 ,从本土艺术的南北分流的考察和上古艺术的东西对比研究中 ,发绎其独创一格的创造精神     

Attracting Micro‐Enterprises To Learning

Micro‐enterprises, i.e. firms with less than 10 employees, are traditionally the hardest to engage in learning; they are also least likely to participate in such measures as business advice and guidance provision and initiatives to support information communication technology (ICT) adoption. Through a community‐based initiative initially targeting parents (unemployed or employed) to participate in ICT, 30 micro‐enterprises were attracted to learning for the first time. These companies had carefully avoided similar initiatives taking place locally, which emphasized business success and growth; they had only participated in this ICT skills training because of their children. The paper takes a case study approach to evaluate the reasons for participation, explores barriers and implications for those organizing similar activities, and calls for a more holistic view of owners and managers of small firms as fathers, mothers, etc. rather than just as ‘entrepreneurs’.
