水、油污中无电流斑电击死大鼠皮肤和心肌的病变

目的探讨水中、油污中无电流斑电击死法医学鉴定的病理形态学依据。方法 SD大鼠28只,分为水中、油污中无电流斑电击死各1组,典型电流斑组、正常对照组、死后电击组、死后水中、油污中电击各1组共7组。采用肉眼、光镜及投射电镜观察水中、油污中无电流斑电击死大鼠皮肤和心肌组织病理学改变,并与其它各组进行比较。结果采用肉眼观察,生前水中、油污中无电流斑电击死大鼠皮肤未见明显电流斑。普通光镜观察,可见电击中心部位表皮变性坏死、脱落,表皮细胞变薄、致密,表皮细胞或/和毛囊、汗腺、皮脂腺发生极性化改变。电镜观察,透明层和角质层分离脱落,基底细胞肿胀、细胞器减少、核固缩,汗腺导管上皮肿胀,棘细胞中粗面内质网扩张融合成泡状,线粒体肿胀空泡化;但光镜与电镜的变化与生前电击死比较不明显、典型。而死后电击组皮肤则无明显病理学改变。实验各组大鼠心肌的改变与皮肤改变类同。结论采用光镜和投透射电镜观察在潮湿环境中电击死的组织病理学改变,可为无电流斑电击死提供依据。     

Gender aspects of inheritance strategies and land transmission in rural Scania,Sweden, 1720–1840

This study deals with gender aspects of land transmissions in pre-industrial Sweden. Although not supported by law, a clear mentality of male primogeniture among peasants existed in the Swedish countryside in the 18th century. In many cases, however, this ideal could never be realized, making the idea of the “family farm,” handed down from father to son for generations, more of a myth than a reality. This study uses postmortem inventories linked to tax registers and family reconstitutions for a sample of parishes in southern Sweden to show that various strategies were chosen when transferring the farm after the death of the husband or wife. Although sons were more likely to take over the farms, daughters (or more correctly sons-in-law) also frequently did so, as did, sometimes, more distant kin and non-kin. Moreover, it was not the case, as has sometimes been maintained, that daughters took over the farm only when no able-bodied sons were available. On the contrary, daughters (sons-in-law) quite frequently took over the farm even when sons were present. The decision on land transmission was part of a more general family strategy concerning reproduction (access to marriage and household formation) as well as old-age security.     

The role of education in facilitating risk-taking and innovation in agriculture

The impact of education on farmers' attitudes toward endogenous risk (measured using an attitude survey instrument) is estimated with household data from rural Ethiopia. Education of the household head is found to decrease risk-aversion. Next, the effects of education and risk attitudes on technology adoption are estimated. Schooling encourages farmers to adopt innovations, whereas risk-aversion reduces the probability of adoption. Thus, we find that schooling encourages innovation, a potentially risky undertaking, not only directly but also indirectly, through its effect upon attitudes toward risk. To the extent that educated farmers are early innovators and are copied by those with less schooling (as other research on the same data has shown), the reduction of riskaversion not only has private benefits for those with education but also may have externality benefits.     

Understanding the survival of post-Communist corruption in contemporary Russia: the influence of historical legacies

Corruption is widespread throughout the former Communist states, and it is particularly severe and entrenched in Russia. Despite the fact that Russia's contemporary corruption has recently become a subject of analysis, there is, however, no study that has addressed the role of the Communist legacy in the development of various aspects of corruption. This paper contributes to the debates through, first, disentangling the complex phenomenon that is corruption, and focusing on its three aspects: supply, demand, and the attitude of the population. Second, the paper also contributes to the literature on modern corruption by explicitly focusing on the role of the historical legacy in these different aspects of corruption. The study is based on several rich data-sets on corruption and on an original data-set compiled to measure the percentage share of Communists in various regions of Russia in the last decades of the USSR (1970s–1980s). The analysis presented in the paper uncovers different roles of the Communist legacies across the development of various aspects of corruption. By doing so, the paper contributes to the literature on historical legacies in general, on Communist legacies in particular, as well as to the broader literature on the causes of corruption in transitional societies.     

Methodological challenges in doing ethnomathematical research

Abstract

Researchers in ethnomathematics are confronted by a variety of methodological questions when they carry out ethnomathematical research. These have to deal with: participants and knowledge holders; language used in research; interviews and observations; familiarity (or lack thereof) with the knowledge holders; mathematical analysis of cultural artefacts; etc. Knowledge in this field engages with indigenous knowledge systems. This article primarily deals with indigenous games which the author researched. He proceeds to explore questions which arose and to provide possible solutions. The author also reflects on and analyses other studies that have grappled with the questions and draws on the implications and insights of these studies in constructing the suggested answers. The article therefore demonstrates that ethnomathematical research contributes to the demystification of the historical false projection by colonialism that Africa and Africans were and are not culturally embedded in mathematics – especially applied mathematics.     

Strengthening Intergenerational/InterculturalTies in Immigrant Families (SITIF)

Abstract

Intergenerational/intercultural conflict is a significant stressor in immigrant families that occurs because of differential acculturation between migrant parents and their children. In spite of its negative mental health consequences, few empirically tested interventions address this problem. Strengthening Intergenerational/Intercultural Ties in Immigrant Families (SITIF) is a culturally-sensitive, community based intervention that aims to strengthen the intergenerational relationship. It promotes immigrant parents' emotional awareness and empathy for their children's experiences, cognitive knowledge and understanding of differences between their native and American cultures, and teaches behavioral parenting skills with the objective of enhancing intergenerational intimacy. SITIF was tested with a group of 16 middle class and 14 working class immigrant Chinese parents. Using objective and subjective assessment tools, the findings provide empirical support for SFTiF's effectiveness in enhancing parenting skills and strengthening the inter-generational relationship in immigrant Chinese American families.     

Commodities and economic growth

The process of social integration of the people associated with immigrant organisations, and the social (and potentially religious) change that comes with it, present the organisations with the difficult challenge of justifying their legitimacy to various societal actors. This is certainly true of Muslim organisations in Western immigration societies. In Germany, this process is quite clearly reflected within the community of established organisations, which play a part in creating intergenerational change. This is not to say, however, that they will be the only relevant – or even the predominant – actors involved in establishing Islam in Germany in the future, despite their roots in their countries of origin, nor that they will automatically become redundant over time.     

Differences in intergenerational fertility associations by sex and race in Saba,Dutch Caribbean, 1876–2004

This study examines the intergenerational transmission of fertility behavior in Saba, Dutch Caribbean from 1876 to 2004 using reconstituted genealogies. Pearson product-moment correlation coefficients of several fertility measures and event-history models of age at first birth are used to explore relationships between the fertility of mothers and their children. The strength of intergenerational fertility ties varies by race and gender. Individuals that are better positioned to realize their fertility preferences have the strongest intergenerational associations, while individuals with the most limited reproductive options have the weakest intergenerational associations. This evidence supports hypotheses that posit the intergenerational transmission of attitudes, goals, and behaviors and the ability to act on those preferences as drivers of the presence or magnitude of links between the fertility of parents and their children.

论中国文学传播的三种历史形态

中国文学在历史上的几次重大转型,都是伴随着语言及传播工具的革新而向前发展的。“言文疏离”代表着中国古代文学传播形态或者说是中国古代文学的形态样式;现代以来,白话文的文学范式体现了具有“言文合一”特征的现代精英文学传播形态;大众媒体出现之后,有了电影文学、电视文学、广播文学、报刊文学,而网络媒体的出现,有效地催生出以电子传媒为载体、具有“精英”与“草根”相融合特征的文学传播形态。
