The rate of dissipation of mouth alcohol in alcohol positive subjects

Seven subjects participated in a two-part study to evaluate mouth alcohol dissipation in alcohol positive subjects. In part one, subjects rinsed their mouths with a vodka solution and were breath tested after 1, 2, 3, 4, and 5 min intervals. On average, breath alcohol concentration (BrAC) decreased 20.4% (range 3.2-47.9%) between 1 and 2 min after rinsing. In part two of the study, multiple breath tests were administered after rinsing once with the vodka solution. The BrAC decreased more than 0.020 g/210 L between the first and second tests for all subjects (average 0.095 g/210 L, range 0.021-0.162 g/210 L). The average time for subjects to reach their unbiased BrAC was 9.35 min (range 4-13 min) after rinsing. This study reaffirms the need for duplicate breath testing and confirms that the minimum of a 15-min observation period is sufficient for mouth alcohol to dissipate in alcohol positive subjects.     

Alcohol and Drug Mitigation in Capital Murder Trials: Implications for Sentencing Decisions

Analyses of the impact on sentencing when alcohol and drug‐related mitigation is used in the sentencing phases of capital murder trials is virtually absent from the existing literature. The present study addresses this by exploring the effect of having mitigation with alcohol and drug themes accepted in a large sample (n = 804) of capital murder trials in North Carolina. Logistic regression analyses that include a number of relevant control variables reveal no substantive impacts of having alcohol mitigation accepted by capital murder juries, but drug mitigators that were either accepted or rejected by juries were associated with an increased risk of receiving a death sentence. Possible reasons for the results and their implications are discussed and suggestions are made for further study of the effects of alcohol/drug mitigation in capital trials.     

从“血荒”现象看《献血法》在实施中的问题与完善

我国《献血法》在实施中存在一些问题：“血荒”现象在很多地方存在;目前的还血政策不能很好地激励公民献血的积极性;法律对医疗机构紧急用血规定不完善,“见死不救”,“救人违法”的矛盾在现实中还存在;部分临床用血的血液来源存在安全隐患。应当教育、动员、招募一支固定无偿献血者队伍,适当放宽献血的条件。提高血站的管理水平和服务质量、加强无偿献血及免费用血系统的网络化建设、适当扩大医疗机构在紧急用血时的权限。     

顶空GC／MS法检验血液中的硫化氢

目的建立血液中硫化氢的气相色谱质谱联用分析方法。方法取心血3mL-5mL,置于20mL顶空瓶中,加入1g氯化钠,加3mL-5mL蒸馏水,加入2mol／L盐酸1mL,加盖密封,混匀后于80℃水浴中加热20min。取液上气体0．5mL进样分析。结果在中毒死亡者的心血中检出硫化氢,保留时间参考值为3．6min。结论该方法可用于刑事案件中硫化氢的快速分析。     

酸性黄显现非渗透性客体上血潜手印初步探究

目的建立一种酸性黄显现非渗透性客体上血潜手印的方法。方法制备白色瓷砖、黑色塑料袋、黑色瓷瓶、易拉罐侧面、深色铁质茶叶盒等为客体的捺印手印,配置以酸性黄作为主要成分的染色剂,对其进行固定、染色、漂洗,在多波段光源下观察。结果在440nm激发光源条件下,通过橙色护目镜观察有很强的黄色荧光特征。结论酸性黄显现法具有操作简单、显现效果明显、能排除深色背景干扰的特点,容易推广使用。     

试析三岩社会的农牧二元经济

为克服土地资源的不足,三岩峡谷历史地形成了农业与牧业两种生产方式并存的经济结构。农牧并举的二元经济结构也在很大程度上影响了三岩峡谷内部的社会及文化。与土地相关的一系列技术与文化成为当地的文化核心,而其他的文化要素都根源于三岩人使用土地的技术。由此导致三岩的二元结构并没有与社会的阶序化相结合,也没有形成人群之外的二元划分,而是始终依附于特定生态与自然环境以及与此相适应的血缘群体。     

基层维稳视阈下破解非正常上访难题的路径探析

非正常上访与基层维稳的内在勾连关系表现为:非正常上访意味着基层维稳过程中民众与基层政府间无法进行有效的对话和沟通,以及基层维稳运行过程中民众对基层政治主体、治理规范和程序的不认同。当前非正常上访被广泛地视为一种严峻的社会危机而予以"问题化",并呈现出非正常上访的主体向体制内延伸及非正常上访的方式暴戾化的动向。要有效破解非正常上访问题,应当从以下几个方面入手:一是提高司法公信力,防止法律纠纷溢出司法渠道;二是完善信访问责制度,防止民众将非正常上访作为解决问题的博弈手段;三是完善人大代表的民意沟通功能,防止民众将所有的诉求向基层政府倾泻。     

政府管理与基层自治协调困境研究

政府行政管理与基层群众自治是两种不同的社会治理机制,二者具有统一的社会目标——社会治理。但因二者在内在机制、价值取向、运作方式等方面的不同,导致二者的协调陷入困境。协调两种治理机制,是建立科学治理结构的必然要求。要从合理调整基层政府管理职能,培育基层群众的自治观念和增强基层自治组织的利益聚合与表达功能三个方面入手加以协调。     

试论国家治理现代化视域下的基层群众自治制度

推进国家治理体系和治理能力现代化是完善和发展中国特色社会主义制度的必然要求。基层群众自治现代化是国家治理体系和治理能力现代化的题中之义和基础工程。国家治理现代化,涉及国家治理的各个层面,其中,观念和制度的现代化尤为重要。     

Detection of Denatonium Benzoate (Bitrex) Remnants in Noncommercial Alcoholic Beverages by Raman Spectroscopy

Illegal alcoholic beverages are often introduced into market using cheap technical alcohol, which is contaminated by denatonium benzoate (Bitrex) of very small concentration. Bitrex is the most bitter chemical compound and has to be removed before alcohol consumption. The home‐made methods utilize sodium hypochlorite to disintegrate particles of denatonium benzoate in alcohol and to remove bitter taste before trading. In this experimental studies, we propose a novel method that detects in a fast way the remnants of denatonium benzoate in dubious alcohol samples by Raman spectroscopy. This method applies a portable Raman spectrometer of excitation wavelength 785 nm and utilizes the effect of surface‐enhanced Raman spectroscopy (SERS) to recognize the suspected alcoholic beverages. High effectiveness (over 98%) of YES/NO classification of the investigated samples was observed when the nonlinear algorithm support vector machine (SVM) was exploited at carefully adjusted detection parameters. The method can identify illicit alcohol within minutes.
