Detection of cannabinoids in homicide victims and motor vehicle fatalities

A gas chromatographic/mass spectrometric (GC/MS) procedure is described for the detection and measurement of delta 9-tetrahydrocannabinol, 11-hydroxy-delta 9-tetrahydrocannabinol, and 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in blood, or 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in urine. About 50% of all homicide victims and motor vehicle drivers killed in Bexar County in 1985 were tested for the presence of cannabinoids. Of 130 homicides and 69 drivers tested, blood was analyzed primarily in all but 15 and 3 cases, respectively. In these latter cases, blood analyzed after urine was found to be positive. Of the homicide victims, 44 (34%), and of all drivers, 19 (28%), tested were positive for one or more of the cannabinoids. As a separate group, 16 motorcycle drivers tested had 38% positive as compared with 25% of the other vehicle drivers. Ethyl alcohol was present in 55% of the drivers, and in 63% of the homicide victims. Drugs other than alcohol or cannabinoids were found in 10% of the drivers, and in 12% of the homicide victims.     

浅谈我国高校生态教育建设

随着全球经济的飞速发展,全球性的生态环境危机引起各国的广泛关注,我国也提出了树立科学发展观、构建和谐社会的问题。教育是实现可持续发展战略的关键一环,生态环境素质也已经成为21世纪人才必须具备的基本素质之一,而高校是培养社会人才的摇篮,当前我国高校的生态环境教育极其缺乏,高校生态环境教育亟待加强。     

西海固的梦想

<正>In 2005,I,with eight schoolmates from Xiamen University,went to Xihaigu in Ningxia to be a supporting teacher for a year..This is intended to tell a western China what I have seen and experienced as well as authentic stories about the children in bitter pursuit of their ideals on the plateau.     

15个基因座复合扩增体系的建立及新疆维吾尔族遗传多态性

目的建立15个基因座五色荧光复合扩增体系,并调查新疆维吾尔族的遗传多态性。方法筛选STR基因座,等位基因测序后按照重复序列重复次数命名,对建立的15个基因座五色荧光复合扩增体系进行灵敏度、种属特异性、同一性及稳定性检测,对新疆维吾尔族群体进行遗传多态性分析,与西藏藏族、岫岩满族、广州汉族进行群体间比较。结果建立了15个基因座复合扩增体系,检测灵敏度为0.3 ng,具有良好的种属特异性、同一性和稳定性。新疆维吾尔族13个常染色体STR基因座的基因频率分布符合Hardy-Weinberg平衡,无连锁不平衡现象,大部分基因座在群体间差异具有统计学意义。结论建立的体系具有法医物证学应用价值,13个常染色体STR基因座在新疆维吾尔族群体多态性高,适合于亲子鉴定及个人识别,可作为现有基因座的补充。     

The Erratic Behavior of Lesions in Burnt Bone

This study analyses depressed fractures (by blunt force trauma) and circular full‐thickness injuries (drill injuries and gunshot wounds) in charred bones. Fifty bovine ribs (total 104 lesions) were divided into three groups. The first group consisted in 20 depressed hammer‐produced fractures; in the second one, 60 round drill‐holes were produced (30 circular, 30 semicircular); in the third group, 12 fleshed and 12 skeletonized ribs were hit by 9‐mm bullets. Each specimen was carbonized in an electric oven up to 800°C. Morphological and metric analyses were performed before and after: morphological features were preserved, but depressed fractures showed an increase in their dimensions (p‐value < 0.05); the drilled holes shrunk (p‐value < 0.01); the charring cycle increased the number of fractures in samples with gunshot wounds differently in fleshed and defleshed ribs. This study showed the complex behavior of charred bone, for what concerns the interpretation of trauma and how caution should be applied.     

重大疫情防控背景下开展群众工作的意义与路径

重大疫情防控事关群众切身利益、社会大局稳定、国家安全和发展,广大人民群众是防控重大疫情的主体,是打好疫情防控阻击战、歼灭战的关键力量。党和政府在应对重大疫情的过程中积极开展群众工作,有助于及时遏制疫情蔓延,稳定社会秩序;维护群众切身利益,增强群众政治认同;磨炼党员干部,完善群众工作机制;推进国家治理现代化,展现良好国际形象。重大疫情防控背景下的群众工作主要通过引导、组织、反馈、保障四个方面发挥作用。     

改府规模与结构优化的维度与性质

政府规模与结构优化是近年来学术界与实践领域特别关注的一个问题.然而,目前的研究主要借助于经济学领域关于政府规模与结构优化的概念体系,而没有形成从公共管理的角度来探讨这一问题的概念体系,由此导致关于政府规模与结构优化的理论研究与实践探索出现某些偏颇.从公共管理的角度上说,我们认为,政府规模就是政府在社会、经济、政治、文化等领域的活动范围以及政府行为对个体或组织的行为所产生的影响;政府规模结构是指政府规模的组织构成、内容构成以及组织-内容匹配性构成.因此,政府规模与结构应该从政府活动、行为及其社会影响三个维度进行优化.     

城市基层社会的数字化治理

北京市X区J街道H社区在社会文化建设、社会服务提供、基层民主选举等几个领域内所发生的“治理一应对”的运作过程说明：当前城市基层社会的治理在很多方面表现为一种“数字化治理”模式,治理对象不是社区里的人或事,而是档案、数据、文牍等数字化内容,以此达到掌控基层社会情况、增加合法性、突出政绩等目的。同时,这种治理模式也直接促使社区事务执行者在不断提高文牍技术、注重细节、追求形式化的同时,采取变通、重新解释、选择性关注等方式,形成了新的社区运作逻辑和基层应对策略。     

论我国“小产权房”合法化的实现与障碍

“小产权房”是否合法化的问题已成为“小产权房”问题争论的焦点内容.纵观中国现行法律,不难发现关于“小产权房”“违法”的相关立法之间存在着逻辑上和法律上的种种矛盾与冲突.通过对“小产权房”的立法以及相关法律规章的梳理和分析发现,在我国“小产权房”应当实现合法化.“小产权房”应当拥有明确的法律定位,并应通过立法及相关配套政策的实施促进我国“小产权房”合法化的步伐.
