不同集卵方法收集的抗苯并咪唑捻转血矛线虫卵的发育试验

用饱和盐水、饱和糖水漂浮法获得抗苯并咪唑(benzimidazole)的捻转血矛线虫(Hae monchus contortus)虫卵,在实验室进行了在不同浓度的苯并咪唑药液中保存不同时间的虫卵发育试验。结果显示,用2种集卵方法获取的虫卵在虫卵发育试验中仅有不足以影响虫卵发育的微小差异,对整体试验也没有实质性的影响,表明2种集卵方法都可以作为该试验获取虫卵的方法;不同保存时间的苯并咪唑药液的试验结果也差别不大,对试验也没有实质性的影响。     

Melody and Law's Mindfulness of Time

Abstract. A structured awareness of time lies at the core of the law's distinctive normativity. Melody is offered as a rough model of this mindfulness of time, since some important features of this awareness are also present in a hearer's grasp of melody. The model of melody is used, first, to identify some temporal dimensions of intentional action and then to highlight law's mindfulness of time. Its role in the structure of legal thinking, and especially in precedent‐sensitive legal reasoning, is explored. This article argues further that melody‐modeled mindfulness of time is evident also at a deeper and more pervasive level, giving structure to the distinctive mode of law's normative guidance. The article draws one important theoretical consequence from this exploration, namely, that the normative coherence of momentary legal systems depends conceptually on their coherence over time.

Crafting the language of consensus

Conclusion In summary, the consensus process provides a necessary set of procedures and standards that provide the essential foundation for reaching mutually supported settlement of disputes. Adjudicatory or voting processes are antithetical to the very nature of the consensus process. When voting takes place, winners and losers are explicitly defined. This can lead to lessened support for implementation of solutions—and even to the losers preferring that implementation fail.As with any other processes, consensus-based processes can—and, at times, should—fail. Where consensus fails, participants will have recourse to other alternatives for making decisions, including administrative, legal, and political forums, the alternative forums which provided the impetus for disputing parties to seek mutually agreeable solutions through a consensus process.

Unexplained sudden death and the likelihood of drug abuse

The common history of drug abuse in adults with an undetermined cause of death has led us to hypothesize that chronic drug abuse increases the risk of sudden death. To begin evaluating this hypothesis, we conducted a retrospective case-control study of 61 decedents whose cause of death remained undetermined following autopsy matched one to one to a control group of pedestrians or passengers killed in motor vehicle collisions. In 21 pairs, the case subject had evidence of drug abuse but the control did not, and in 5 cases the reverse was true. Analysis showed that individuals with an undetermined cause of death are 4.2 times more likely to have evidence of drug abuse than are victims of a motor vehicle collision.     

The Richard Cory phenomenon: suicide and wealth in Kansas City, Missouri

This case-control study investigates the relationship between suicide and wealth in Kansas City, Missouri. House and personal property appraisal data on all victims of suicide from 1998 and 2002 and victims from a control population of deaths reported to the Jackson County Medical Examiner during the same time interval were obtained from the Jackson County Government website. The controls were matched to suicide cases by race, gender, year of death, and age at death (+/- 1 year). Data from the 426 members of each group of suicides and controls indicate that suicide victims were: 1) 77% more likely than controls to have lived in houses rather than in apartments or trailers, 2) more likely than controls to have lived in more expensive houses (mean values dollar 70,143 versus dolllar 61,513 respectively, p = 0.04) and 3) more likely to have killed themselves because of factors other than financial strain (8.0% of suicides showed financial strain).
