人离体肝组织胺类产生与死亡时间和环境温度的关系

目的探讨在不同环境温度下,人离体肝组织中有机胺类产生量随死亡时间变化的规律,为某些碎尸案的死亡时间推断提供参考资料。方法应用高效液相色谱仪外标法,动态检测人离体肝组织中组胺、腐胺、尸胺和未腐败氨基酸含量。结果在8℃、15℃、23℃和32℃环境下,有机胺类产生量分别于人死后肝脏即刻离体69h、54h、40h和33h趋于最大值,并且在到达峰值之前,各温度组离体肝组织中有机胺类生成量均与死亡时间成正比关系。结论人离体肝组织中有机胺类产生量与死亡时间和环境温度在一定范围内均呈正相关。     

The Trilateral cooperation

Legal context: The relatively informal agreements setting up the TrilateralCooperation (TC) among the world's three most important patentoffices are contrasted with formal multinational treaties suchas the Patent Law Treaty and the abortive Substantive PatentLaw Treaty. Key points: After its inception in 1983, the TC concentrated initially ondeveloping and implementing standards for electronic storageand retrieval of prior art documents, and facilitation of searching.This was later extended to electronic sharing of priority documentsand to standardization and searching of DNA sequence databases.More recently emphasis has been placed on harmonization of searchingand examination procedures, and working groups have comparedthe approaches of the Trilateral Offices (TOs) to the patentabilityof claims in areas of new technology. Encouragingly, the resultsare usually the same, although the specific objections raisedmay differ. The ultimate goal is to reach a situation in whicha claim allowed by one TO would be accepted by the others withoutfurther examination. Practical significance: The TC has already facilitated search and examination, leadingto lower costs and shorter pendency times than would otherwisebe the case. Further progress depends on harmonization of substantivepatent law, which in turn depends on the willingness of theUSA to accept a first-to-file system.     

INTRODUCING PERSPECTIVES IN FAMILY LAW AND SOCIAL SCIENCE RESEARCH

This article provides an editorial introduction to the following three related articles on the growing use and influence of social science research in family law. It first considers why this has become problematic and identifies some common strategies used by advocates, sometimes under the guise of scholarship, to destroy the standing of research findings contrary to their ideological or political position. Then it discusses briefly the remedies proposed to mitigate these kinds of problems within the following three articles.     

THE CAUSES OF GIRLS’ DELINQUENCY AND THEIR PROGRAM IMPLICATIONS

This article summarizes some of the literature reviewed by the Girls Study Group, which is a federally funded project aimed at assessing the causes of girls’ delinquency as well as evaluating programs to address it. The literature reveals that a number of factors such as family dysfunction, involvement with antisocial peers, and living in disadvantaged neighborhoods are correlated with delinquency for both boys and girls. Some factors, however, are gender sensitive, meaning that either girls are more exposed to a given risk factor than boys or react somewhat differently to a given risk factor. Girls have higher rates of exposure to sexual assault, which is associated with delinquency and, although more research is needed, they are more affected by the impacts of early puberty, when it is coupled with harsh parenting and disadvantaged neighborhoods. This article discusses some implications of the research on correlates of delinquency for programming for girls and makes recommendations for program selection.     

PUNCHING THE PARENTING TIME CLOCK: THE APPROXIMATION RULE,SOCIAL SCIENCE,AND THE BASEBALL BAT KIDS*

The American Law Institute proposes that in contested physical custody cases the court should allocate to each parent a proportion of the child's time that approximates the proportion of time each has spent performing caretaking functions in the past. Examined through the lens of child development research, the approximation rule is unlikely to improve on the best interests standard. It is difficult to apply; is perceived as gender‐biased; creates a new focus for disputing parents; renders a poor estimate of parents’ contributions to their child's best interests; overlooks parents’ intangible, yet significant, contributions to their child's well‐being; and miscalculates the essence of how a child experiences the family. A preferable alternative is a better defined, contemporary best interests standard that accommodates new knowledge and reforms that encourage nonadversarial, individualized resolutions of custody disputes.
