刑法中的"自然身份犯"概念质疑

长期以来,我国刑法理论的学说在论及刑法中的特殊主体时,一般认为以特殊主体为犯罪成立条件或刑罚加减事由的身份犯可以其形成方式的不同而划分为自然身份犯和法定身份犯,其中自然身份犯中的自然身份主体的形成来源于诸如男女性别、亲属等自然事实。本文通过严密的论证,阐明了刑法中自然身份及自然身份犯的概念在理论上是不妥当的,应从理论中予以剔除。     

Testing symmetry under a skew Laplace model

We develop tests of hypothesis about symmetry based on samples from possibly asymmetric Laplace distributions and present exact and limiting distribution of the test statistics. We postulate that the test statistic derived under the Laplace model is a rational choice as a measure of skewness and can be used in testing symmetry for other, quite general classes of skew distributions. Our results are applied to foreign exchange rates for 15 currencies.     

平生重交结,为多山水乐 --孟浩然的自我审视与人格追求

历来人们大多认为孟浩然的归隐源于仕途上的挫折和政治的毫无出路,这一看法有些一厢情愿,忽略了对孟浩然自身兴趣的关注.虽然有关孟浩然的史料相当稀少,但从现存他的诗歌中,我们还是能够发现他对山水的爱好是由衷的.这决定了他交游的对象、他诗歌创作的题材和艺术风格.     

Do You Speak English? Language Barriers in Child Protection Social Work with Minority Ethnic Families

This paper critically evaluates research and literature on childprotection social work practice with minority ethnic familieswho speak little or no English. Though the focus is on childprotection, many of the themes raised should be transferableacross to other areas and disciplines. Specifically, the paperfocuses on the limitations and difficulties of using professionalinterpreters in child protection work and covers themes likethe availability of interpreters, the role of interpreters,suitability of interpreters, the interpretation of particularwords and phrases, and manipulating the interpreting process.The paper then moves on to address the important but often neglectedarea of using children as interpreters, and ends by consideringthe broader issue of how language barriers can exacerbate discriminationagainst minority ethnic families.

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;

       

试论社会技术创新

无论从逻辑上还是从实践上讲,社会技术和自然技术一样是确定存在的。社会技术也是第一生产力,发挥着和自然技术一样重要的作用。在技术领域中引入社会技术就必然要求创新和发展技术观念和技术概念,突破对传统技术定义的局限。在技术观念上进行变革和创新。
