单亲亲子鉴定的分析研究

目的从理论和实际应用方面客观评价13～15个STR位点应用于单亲亲子鉴定的准确性。方法依据中国人群基因频率资料,计算单亲亲子鉴定的非父排除率及单亲亲子鉴定的亲子关系概率,并选择有明确排除结论的104例排除案例,分析统计其中父-子二联体出现的排除指标数。结果对于单亲亲子鉴定,选用13～15个STR位点,联合非父排除率为0.9805～0.9906;亲子关系概率均大于99.73%。104例二联体排除案例中,有3例的排除指标数小于2,未发现排除指标为零的现象。结论若应用ProfilerPlus和CofilerPlus试剂盒的13个STR位点进行日常单亲亲子鉴定工作,存在微弱漏判非父的风险,必要时增加检测指标数。不排除案例的单亲亲子鉴定,其亲子概率均可达国际认定标准。

Fatal poisoning in drug addicts in the Nordic countries in 2007

The frequency of medico-legally examined fatal poisonings in 2007 among drug addicts was investigated in five Nordic countries; Denmark, Finland, Iceland, Norway, and Sweden. The number of deaths, age, sex, place of death, main intoxicant, and other drugs present in blood samples were recorded to obtain national and comparable Nordic data, as well as data to compare with earlier studies in 2002, 1997, and 1991. Norway had the highest incidence of drug addict deaths by poisoning followed by Denmark, with 8.24 and 6.92 per 100,000 inhabitants, respectively. The death rates in Finland (4.02), Iceland (4.56), and Sweden (3.53) were about half that of Norway and Denmark. Compared with earlier studies, the death rates were unchanged in Denmark and Norway, but increased in Finland, Iceland, and Sweden. In all countries, fewer deaths (29-35%) were recorded in the capital area compared with earlier studies. Females accounted for 11-19% of the fatal poisonings. Iceland deviates with a more equal distribution between men and women (40%). Deaths from methadone overdoses increased in all Nordic countries, and methadone was the main intoxicant in Denmark in 2007, accounting for 51% of the poisonings. In Norway and Sweden, heroin/morphine was still the main intoxicant with a frequency of 68% and 48%, respectively. In Iceland, 3 deaths each were due to heroin/morphine and methadone, respectively. Finland differs from other Nordic countries in having a high number of poisonings caused by buprenorphine and very few caused by heroin/morphine. The total number of buprenorphine deaths in Finland doubled from 16 in 2002 to 32 in 2007, where it constituted 25% of deaths. The general toxicological screening program showed widespread multi-drug use in all countries. The median number of drugs per case varied from 3 to 5. The most frequently detected substances were heroin/morphine, methadone, buprenorphine, tramadol, amphetamine, cocaine, tetrahydrocannabinol, benzodiazepines and ethanol.     

Trends in Non-Muslim Divorces in Singapore

This article examines the trends and patterns in the way thesecular divorce law has been utilized by couples in Singaporeseeking to end their marriage. Social and demographic featuresof the divorcing couples, as well as the ‘fact’relied on in support of their divorce petitions, are studiedand compared to earlier analyses. It is found that while somepatterns observed by earlier researchers have remained intact,others have changed. This article suggests explanations forthese observed patterns and contributes to the discussion onwhether and how the divorce law can be improved in Singaporeand elsewhere.

Differences in female and male involvement in lethal violence in Russia

Relatively little is known of the distributions of homicide event characteristics in non-Western nations in which women relative to men are involved. This article utilizes unique homicide narratives drawn from Russian court and police records to compare homicide victim, offender, and event characteristics by sex of victim and separately by sex of offender. Results from logistic regression show that homicides in which a female was the victim or offender were more likely to occur between intimates and to occur in the home, whereas homicides involving males were more likely to occur in a public place, to be alcohol-related, to involve a firearm, and to involve a victim and offender who did not know each other well. These results not only present an important first glimpse at women as homicide victims and offenders in Russia specifically, but also provide a point of comparison with findings from similar analyses undertaken in the West, and present further initial observations upon which to construct a cohesive theory about female involvement in serious violent events.
