低压架空线路雷电感应过电压计算

低压架空线路在野外与雷击点距离较近或由于与建筑物避雷引下线的距离较近,因雷电电磁场作用于架空线路,在线上产生的感应过电压会造成线路对杆塔横担闪络.采用电磁场理论,分析了低压架空线路旁接闪物体及架空线路高度、线路与雷击点间距等参数对架空线路感应过电压的影响,推导出了架空线路附近出现雷击时在架空线路上的感应过电压计算公式.     

Holocaust Historiography: The Return of Antisemitism and Ethnic Stereotypes as Major Themes

Ofer addresses the return of antisemitism as a major factor in explanations of the Final Solution, and explores the significance and meaning of the reinstatement of antisemitism at the centre of historical work on the subject. She refers mostly to three books published in the mid-1990s. The one that caused the greatest uproar was Daniel Jonah Goldhagen's Hitler's Willing Executioners: Ordinary Germans and the Holocaust, the title of which makes clear its thesis, as does that of John Weiss's Ideology of Death: Why the Holocaust Happened in Germany. The third book discussed is the first volume of Saul Friedländer's Nazi Germany and the Jews: The Years of Persecution, 1933-1939. Ofer demonstrates the role of antisemitism in explaining the Holocaust at different stages of post-war research, the historiographical trends in histories of the Holocaust and the transition that these three publications suggest. The main part of the article addresses these books which, despite their common message, are very different in their methodologies and the perceptions of their authors, and are also associated with different historiographic schools.     

Confessing their Crime: Factors Influencing the Offender’s Decision to Confess to the Police

Confessions are crucial to successful police investigations but scholars have significantly overlooked factors that contribute to an offender’s decision to confess a crime. This study aims to examine a large array of factors that play a role in the offender’s decision to confess a crime to the police and potential interaction effect among them. A total of 221 adult males incarcerated in a federal Canadian penitentiary were recruited. Correctional files, police reports, and offenders’ self‐reported data were collected and analyzed. Controlling for sociodemographic, criminological, and contextual factors, a series of logistic regression analyses were conducted. Findings highlighted the predominant role of police evidence over and above other factors analyzed. Furthermore, sociodemographic and criminological factors played a more important role in the offender’s decision to confess when police evidence was weak. Findings are discussed in light of the current scientific literature on the determinants of offenders’ decision to confess their crime.

ROMANTIC PARTNERS' INFLUENCE ON MEN'S LIKELIHOOD OF ARREST IN EARLY ADULTHOOD*

Female romantic partners' influence on official crime occurrence for men across a 12‐year period in early adulthood was examined within a comprehensive dynamic prediction model, including both social learning and social control predictors. We hypothesized that relationship stability, rather than attachment to partner, would be associated with reduced likelihood of crime, whereas women's antisocial behavior would be a risk factor, along with deviant peer association. Models were tested on a sample of at‐risk men [the Oregon Youth Study (OYS)] using zero‐inflated Poisson (ZIP) modeling predicting 1) arrest persistence (class and count) and 2) arrest onset class. The findings indicated that women's antisocial behavior was predictive of both onset and persistence of arrests for men and that deviant peer association was predictive of persistence. Relationship stability was protective against persistence.     

Relative Width and Height of Handwritten Letter

This is an exploratory study that analyzes the width and the height of letters in two texts written by each of the 21 writers analyzed. After detrending the linear, text, and allograph trends, we proceeded to comparing the sizes obtained in different texts. The different detrended series were compared by means of correlation and t‐test. According to the results regarding the width of letters, the texts of 19 of 21 writers correlated strongly, whereas the texts of two writers did not correlate with the limits of the threshold. With regard to the height of letters, texts written by between 18 and 21 writers of 21 writers correlated strongly, whereas texts that did not correlate were within the threshold value. Regarding both the width and the height of letters, of 21 writers, texts written by between 19 and 21 individuals were found to correlate strongly.

Effects of Parental Differential Treatment on Relationship Quality with Siblings and Parents: Justice Evaluations as Mediators

Based on equity theory, the present study analyzes to what extent justice evaluations mediate the effects of perceived parental differential treatment (PDT) on relationship quality with siblings and parents as experienced in middle adulthood. Middle-aged adult offspring (N = 709) rated how often they and a sibling received parental recognition, nurturance, and demands for assuming filial responsibility. In addition, they indicated their justice evaluations of PDT and completed measures of relationship quality to sibling and parents. Justice evaluations emerged as either partial or complete mediators between PDT and relationship quality. Moreover, justice evaluations turned out to be more powerful predictors of relationship quality to parents than PDT per se. Implications are discussed concerning factors contributing to justice evaluations and the role of PDT within the context of other justice issues in families.     

维生素D受体基因多态性研究进展

维生素D受体(vitaminDreceptor,VDR)基因多态性可能与骨密度、骨质疏松、身高相关。本文作者就近年国内外所开展的VDR基因4个单核苷酸多态性(singlenucleotidepolymorphism,SNP)位点FokI、BsmI、ApaI、TaqI与骨密度、骨质疏松、身高关联性研究进行综述,发现各国的研究结果虽不尽相同,但VDR基因多态性在遗传学、临床内分泌代谢,尤其在法医学领域对身高的研究中,有重要的应用价值。
