Post-Traumatic Stress and Alcohol-Related Problems Following a College Shooting: Effect of Help-Seeking

Our aim was to test the hypothesized relationships between trauma exposure and alcohol-related problems, mediated by PTS symptoms, moderated by prior trauma exposure and help-seeking. Participants were 244 members of a private university who were enrolled or employed at the school on the date of a campus shooting. Online measures were distributed via e-mail in October 2014, and included the AUDIT, BTQ, PCL-5, and self-report measures of trauma exposure and counseling services utilized. The overall moderated mediation model examining the indirect effect of exposure to trauma on alcohol-related problems through PTSD symptoms, moderated by prior trauma and help seeking was significant, β(SE) = .310(.3554), p = .0001. This study highlights the importance of crisis interventions following trauma exposure.     

Bullet Trajectory after Impact on Laminated Particle Board

When reconstructing a bullet's trajectory prior to impact using the spatial orientation between two consecutive bullet defects (e.g., by probing), it is important to take the bullet's deflection into account. The (critical) ricochet angles as well as the vertical and horizontal deflection angles of eight cartridge types on laminated particle board have been studied. For all eight of the cartridge types combined, the critical ricochet angles lie between approximately 14° and 26°, while for the subgroup of the jacketed bullets, this range lies lower, between approximately 14° and 18°. The data from this study can be used to assess the accuracy and precision of the applied method. The results show that the highest deflection angles are seen near the critical ricochet angle. Generally speaking, vertical and horizontal deflection angles can almost be neglected above angles of incidence of 30° or 40° for handgun ammunition when shooting at laminated particle board.     

基层工会组织要努力实现"三个转型"

在当今社会转型时期,基层工会要想成为有为有位的新型组织,更好地履行维护职工合法权益的基本职能,就必须以三个代表重要思想统领工会工作的实践,摒弃计划经济时代形成的传统运行机制.转变观念,服务改革,在干部队伍建设、工作方针、工作模式等方面作重大调整.

借鉴与重塑:我国农地利用权利体系构建的基本思路和框架

我国现行的农地利用制度主要是土地承包经营权制度。将土地承包经营权界定为用益物权是导致当前农地征用征收过程中农民利益严重丧失的一大重要原因。我国农地利用制度的设计基础与大多数大陆法系国家不同。大多数大陆法系国家土地物权制度设计是建立在土地私有制基础上的,而我国实行的是土地公有制,这一基础制度目前是不可动摇的。因而我们应在借鉴英美法系国家地产权制度的基础上重构我国的农地利用制度。农地持有权作为一种独立的权利形态,应该替代土地承包经营权成为我们的现实选择。     

关于公安指挥中心重新定位的思考——首都警方警务指挥体系改革实践的启示

首都警方“加强勤务指挥工作推进社会治安整体防控体系建设”的工作思路,是关于指挥中心重新定位的实践性探索。重新确定指挥中心的地位是社会治安整体防控体系建设的需要,指挥调度作用对象的调整表明指挥中心的职责范围有了重大突破,指挥中心地位及职责范围的重新界定必然要求建立新的运行机制。     

"趋同论"刍议

在中国共产党与民主党派的多党合作中趋同具有必然性,但这种趋同是以中国共产党与民主党派的不同为前提的,其实质是一个不断求同存异的过程。准确把握同和异的辩证关系,是正确认识趋同论的一把钥匙。     

“运行”计算机内“易挥发数据”的取证问题

当前司法实践中对现场中处于运行状态的计算机大多采用“二步式”取证的方式来收集数字证据,即先由侦查人员对涉案计算机实施关机分离和保全,尔后再移交专业机构进行数字证据司法鉴定。该方法虽保障了数字证据的原始性和证明力,但无形之中却造成了存储于RAM中的“易挥发”数据以及其他形式的潜在数字证据的丢失。而计算机信息系统中的这些“易挥发数据”可为案件的侦破提供重要线索和潜在的数字证据,因此进行现场动态分析,收集这些“易挥发数据”对数字案件侦查取证意义重大。
