Fatal Methemoglobinemia Due to Acute Inhalation of Methyl Nitrite in an Industrial Accident

Methyl nitrite is suggested to cause methemoglobinemia by generating methemoglobin, which may be lethal when the methemoglobin concentration exceeds 70%. However, intoxication with methyl nitrite is seldom reported compared with that with other nitrites. Here, we present an industrial accident involving methyl nitrite inhalation during its synthesis process that resulted in three fatalities and one survivor. The autopsy revealed conspicuous blue-gray discoloration in various parts of the body, including the skin, airway mucosa, vessels, brain, heart, and among other areas. The toxicological tests on the deceased showed methemoglobin concentrations in the blood over the lethal level and increased nitrite ion levels in the blood, gastric contents, liver, and lung tissue compared with those in control samples. The cause of death was determined to be methemoglobinemia-induced hypoxia due to methyl nitrite inhalation. This report provides evidence that in methyl nitrite intoxication, exposure duration has a significant influence on the postmortem changes and likelihood of a fatal outcome may be related to the age of the victim. More attention is required regarding the industrial hazards of this substance.

基于精英策略的多目标进化算法的研究

针对基于精英策略的多目标进化算法NSGAⅡ[1]解的多样性降低的缺点,提出了一个分布函数改进其精英策略.通过调节分布函数中的参数,控制精英解的选取范围,使一部分非精英解也能参与到遗传操作中,增加了解的多样性.实验结果表明,改进的多目标进化算法无论在解的多样性方面还是解的收敛性方面都有较大改观,性能明显优于NSGAⅡ.

Reducing intimate partner homicides: The effects of federally-funded shelter service availability in California

Over twenty-five years of policy and scholarly attention to the problem of intimate partner violence appears to have generated greater victim safety. Intimate partner homicides, the most serious form of violence between intimates, have been declining for nearly three decades in many contexts, but not all. This study built on a small number of studies that had advanced knowledge about the policy-relevant factors behind the intimate partner homicide decline. The analysis described here utilized a set of county-level data from California from 1987 to 2000 to estimate the effects of shelter-based service availability on race/ethnicity-specific female intimate partner homicide victimization. The study relied on a new measure of service availability in an attempt to overcome limitations with previously used indicators. This analysis did not reveal an effect of shelter-based service availability and criminal justice system responses on changes in female intimate partner homicide victimizations. Reasons for these findings and suggestions for future research are discussed.     

中国古代秘密侦查方法析评

秘密侦查方法具有其特殊功能,为世界各国所普遍采用。我国古代便产生了广泛而深入的各种秘密侦查方法,其中包括以“侯”侦探,逆用犯罪人;设告密箱;跟踪盯梢和狱内侦查等。古代秘密侦查方法具有其合理内核,也为现代秘密侦查方法提供了相当的启示,如善用现代科技,促进秘密侦查方法的完善;面对我国秘密侦查立法的困境,从秘密侦查启动条件、启动主体、秘密侦查适用对象、实施程序、秘密侦查所获取资料的线索以及证据价值、违法秘密侦查的后果等方面完善我国缺失的秘密侦查立法;根据主体、客体、程序和是否穷尽等要素合理适用秘密侦查手段。

音乐心理剧对海洛因依赖者戒毒动机的干预

目的:研究音乐心理剧对我国海洛因依赖者的戒毒动机和操守的临床干预效果。方法:将62名女性海洛因依赖者随机分为实验组(n=31)和对照组(n=31)。实验组进行为期12周的Joseph.J.Moreno音乐心理剧临床干预;对照组常规治疗。将实验组干预后的戒毒动机与干预前及对照组进行比较;追踪所有被试的复吸情况并进行统计;对总体戒毒动机、操守率和各戒毒动机因子进行相关分析,了解干预的方法对戒毒动机和操守率的干预效果。结果:实验组总体戒毒动机与对照组和干预前相比显著提高(P<0.05);总体戒毒动机与"家庭因子"呈显著正性相关(r=0.364)。实验组操守情况(58.06%,18/31)优于对照组(35.48%,11/31),但无统计学意义上的显著性差异(P>0.05)。结论:音乐心理剧临床干预对提高海洛因依赖人群的戒毒动机有明显作用,但在提高复吸率方面效果不明显。提高戒毒动机需要从家庭角度进行干预。由于文化上的差异,本法在临床运用的过程中有些技术的使用存在一定的局限性。

建立适应社会主义市场经济发展的道德体系

市场经济与道德存在着矛盾与对立,但二者之间也存在彼此容纳、彼此依赖、彼此统一的属性。发展社会主义市场经济,不仅要建立相应的法律体系,而且要建立与之相适应的思想道德体系。
