Breaking the intergenerational transmission of child abuse: Beyond the mother-child relationship

Studies comparing abusive and non-abusive parents who were abused as children are reviewed to determine protective factors that may lead to a break in the transmission pattern. Non-abusers have several factors in common. For instance: they have extensive emotional and social support from significant others. they are aware of what happened to them as children and are openly angry about their abuse. and many of them received (psycho)therapy as adolescents or young adults. Discovering protective factors by which some parents overcome a family pattern of abuse is valuable in guiding both prevention and intervention efforts. A brief discussion of the influence of methodological variations of different studies on reported transmission rates precedes the review. Furthermore. attention is given to the underrepresentation of (abusive) fathers in theory as well as in research on child abuse. The effects of undervaluation of gender differences are discussed in terms of their importance in the occurrence and (breaks in the) transmission of child abuse.     

Girls’ Jobs for the Boys? Men,Masculinity and Non‐Traditional Occupations

Occupational segregation by sex remains the most pervasive aspect of the labour market. In the past, most research on this topic has concentrated on explanations of women’s segregation into low paid and low status occupations, or investigations of women who have crossed gender boundaries into men’s jobs, and the potential impact on them and the occupations. In contrast, this article reports on a small‐scale, qualitative study of ten men who have crossed into what are generally defined as ‘women’s jobs’. In doing so, one of the impacts on them has been that they have experienced challenges to their masculine identity from various sources and in a variety of ways. The men’s reactions to these challenges, and their strategies for developing and accommodating their masculinity in light of these challenges, are illuminating. They either attempted to maintain a traditional masculinity by distancing themselves from female colleagues, and/or partially (re)constructed a different masculinity by identifying with their non‐traditional occupations. This they did as often as they deemed necessary as a response to different forms of challenge to their gender identities from both men and women. Finally, the article argues that these responses work to maintain the men as the dominant gender, even in these traditionally defined ‘women’s jobs’.     

从英汉非宾格动词的比较谈汉译英中动词的翻译

传统语法将动词分为及物动词和不及物动词,已不足以反映动词的特性。从生成语法的角度对英汉非宾格动词进行比较之后,将有利于学习和掌握英汉互译。

基于直接接触凝结理论的汽液两相流升压模型

针对汽液两相流升压装置利用经验模型计算的过程中，仅能对出口压力进行计算，且计算值与实验值有较大误差的弱点，提出了用直接接触凝结（DCC）的理论求解汽液两相流的一维理论模型。计算升压装置的最大出口压力，分析其他参量的变化规律。结果表明，汽液两相流在凝结激波前为泡沫流，在凝结激波后完全凝结成单相水的情况下，升压装置的出口压力达到最大值。     

Linguistic differentiation and Mayan language revitalization in Guatemala1

This paper presents a quantitative study of syntactic change in the context of Mayan language revitalization in Guatemala. Quantitative analyses of grammatical variation and code‐switching patterns were used to examine the degree of Spanish influence in the speech of three generations of Sipakapense‐Spanish bilinguals. The younger generations show lower frequencies of code‐switching compared to the oldest generation. In terms of syntactic variation, younger speakers show patterns that suggest a resistance to influence from Spanish. The results suggest that younger speakers are hyperdifferentiating the two languages by avoiding traditional Sipakapense constructions that could be interpreted as resulting from Spanish influence. The analysis highlights the important role of language ideology in cases of language change due to contact and language shift.     

Issues in applying recent CPMP ‘Points to Consider’ and FDA guidance documents with biostatistical implications

The International Conference on Harmonisation guideline ‘Statistical Principles for Clinical Trials’ was adopted by the Committee for Proprietary Medicinal Products (CPMP) in March 1998, and consequently is operational in Europe. Since then more detailed guidance on selected topics has been issued by the CPMP in the form of ‘Points to Consider’ documents. The intent of these was to give guidance particularly to non‐statistical reviewers within regulatory authorities, although of course they also provide a good source of information for pharmaceutical industry statisticians. In addition, the Food and Drug Administration has recently issued a draft guideline on data monitoring committees. In November 2002 a one‐day discussion forum was held in London by Statisticians in the Pharmaceutical Industry (PSI). The aim of the meeting was to discuss how statisticians were responding to some of the issues covered in these new guidelines, and to document consensus views where they existed. The forum was attended by industry, academic and regulatory statisticians. This paper outlines the questions raised, resulting discussions and consensus views reached. It is clear from the guidelines and discussions at the workshop that the statistical analysis strategy must be planned during the design phase of a clinical trial and carefully documented. Once the study is complete the analysis strategy should be thoughtfully executed and the findings reported. Copyright © 2003 John Wiley & Sons, Ltd.     

基于EMD的非线性信号自适应分析

根据EMD分解原理,提出通过选择平均包络中的突变点确定自适应滤波器截止分量阶,以此构造时空滤波器组进行非线性信号自适应分析的方法,成功应用于分析波音737飞机涡轮轴振动信号。从噪声中自适应地提取随转速变化的信号分量和低频振动分量,与小波分析方法相比,在轴向位移检测中取得了更为满意的效果。该方法不仅改进了涡轮轴振动信号分析方法,也适用于解决其他非线性信号的分析问题。
