机采冰冻血小板保存质量指标变化分析

目的:本文通过对30袋机采冰冻血小板-80℃保存120天内质量指标变化,为冰冻血小板有效保存提供理论参考依据。方法:用美国克利夫兰生产的Research二甲基亚砜(DMSO)为冰冻保护剂,-80℃冰冻保存血小板120天,于20、40、80、120天进行计数,分别检测:聚集率、粘附功能、Ⅲ因子活性质量指标、输注后CCI值与冰冻前新鲜血小板进行比较,并随机抽取不同保存时期每样中1份冰冻血小板进行无菌试验。结果:- 80℃保存120天内各时期冰冻血小板的Ⅲ因子活性与新鲜血小板相比差异无显著性(P>0.05);冰冻血小板计数、粘附功能、聚集率与新鲜血小板相比差异有统计学意义(P<0.05),但保存120天内的各时期回收率平均为84.1%,均大于70%。无菌试验均无细菌生长。结论:血小板-80℃冰冻保存120天内进行临床应用是可行的。     

目的犯的犯罪形态研究

本文从目的犯的未完成形态 (包括预备犯、中止犯、未遂犯 )与完成形态 (既遂犯 )、目的犯的共犯形态、目的犯的罪数形态 (包括继续犯、转化犯 )等三个方面对目的犯进行了研究 ,提出了自己的观点。     

我国民主政治发展的路径依赖及路向选择——基于路径依赖理论的分析视角

从路径依赖理论的视角来考察,我国民主政治的发展在取得诸多成就的同时,也存在着思想观念、民主制度体系、民主组织行为等方面的非良性路径依赖,阻碍了我国民主政治的发展。加快我国民主政治发展必须打破非良性的路径依赖,实现路径替代,需要在更新民主观念、深化市场经济体制改革、推进政治体制改革、以及扩大公民有序政治参与等方面做出努力。     

管理模式创新与高校后勤社会化改革

该文对中国高校后勤社会化改革的历程进行回顾和分析,将中国高校目前主要采用的管理模式归结为两大类,即附属模式和独立模式,并采用新公共管理三种基本理论对这两种模式进行比较分析,在此基础上对高校管理模式的创新与重构进行探讨。     

大学生“红色社团”发展现状与开发模型研究

大学生＂红色社团＂是对大学生进行思想政治教育的重要阵地和有效载体,红色社团开发模型以学校培育和支持的马克思主义理论学习实践项目为导向,红色社团开发模型以学生对学习实践马克思主义理论产生兴趣为基础,红色社团开发模型以核心人物的模范作用来带动。     

浅议淫秽物品犯罪的界定

淫秽物品犯罪是指走私、制作、贩卖、传播淫秽物品的行为以及组织进行淫秽表演的行为。这类犯罪侵犯了我国社会风尚中的善良性风尚和性道德。尽管不同国家 (地区 )在不同的时期受到宗教、文化传统、意识形态等因素的影响对某物品是否为淫秽物品的认识存在着差异 ,但淫秽物品最终还是进入人们道德评价、法律评价的视野。     

新旧矛盾、结构矛盾及其关系

新旧矛盾是事物内部新的一方与旧的一方组成的矛盾,其主要特征是相克,在事物发展的质变阶段表现比较突出;结构矛盾是事物内部不同部分、层次之间组成的矛盾,其主要特征是相生,在事物发展的量变阶段表现比较突出。两类矛盾相互交织,相互转化,共同推动着事物的运动和发展。实践中,要正确认识两类矛盾,用不同的思维方式解决不同的矛盾,同时,思维方式还要随矛盾的变化而变化,要注重两种思维方式的有机结合,只有这样,对构建和谐社会才有现实的指导价值。     

Implementation and Optimization of the Sodium‐Rhodizonate Method for Chemographic Shooting Distance Estimation

In shooting incident investigations where it is important to estimate the shooting distance, the sodium‐rhodizonate coloring method has been used for the visualization of GSR patterns extensively. This publication describes the optimization of this method by the use of a heated press for the transfer of GSR traces on garments, as well as variation of a number of other important process parameters. Our final aim for this project was to prepare a formal validation of the coloring method as prerequisite for its inclusion into the scope of ISO17025‐certified methods in the GSR Laboratory. A number of important factors and process parameters were identified, such as buffer composition and pH, type of textile used as a substrate and resolution of the documentation of the results. Results were tested using a synthetic proficiency test. Our optimized method has been found to be a very effective technique for visualization of macroscopic GSR traces.     

Do homicide rates increase during weekends and national holidays?

In the UK there has been limited research examining temporal patterns of homicide. To our knowledge, no studies have linked patterns of homicide to the mental health characteristics of the perpetrator. The study examined a national consecutive case series of homicide offences committed between January 1996 and December 2015 in England. Clinical data were collected by the National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH). During this period 10,563 people committed a homicide. The offences were more likely to occur at the weekend, mostly on a Saturday. Weekend homicides were associated with: perpetrators under the age of 25, males and alcohol consumption. Homicides increased markedly on New Year’s Day, and public holidays. Those with a history of mental illness more commonly committed homicide during weekdays, suggesting a different pattern of offending. No change in pattern was found after licensing hours were extended in 2005 to allow 24-h licencing for the sale of alcohol. A public health approach should focus on educating young people on the health risks associated with alcohol, promoting responsible drinking and conflict avoidance, specifically on special events and at weekends.
