酮洛芬注射液在乳牛体内的残留消除研究

为建立牛乳中酮洛芬的液相色谱-串联质谱(LC-MS/MS)检测方法,牛乳样品经甲醇提取,C18色谱柱分离,采用正离子模式,多反应监测,内标法定量。结果表明,牛乳中酮洛芬的检出限为1μg/kg,定量限为5μg/kg,在5~200μg/kg范围内线性关系良好,相关系数大于0.99。在25~100μg/kg添加水平的回收率为93.3%~107.5%,批内、批间相对标准偏差分别为1.72%~5.46%、1.13%~7.04%。该方法高效、灵敏、准确,可作为牛乳中酮洛芬的检测方法。选用20头健康的泌乳期荷斯坦乳牛,高产、低产各10头,以3 mg/kg剂量肌内注射给药,每天1次,连用3 d,分别于每次给药后第2、15小时采集乳样。每次给药后2 h牛乳中可检出酮洛芬,最高质量分数为(38.43±3.90)μg/kg,停药后15 h均未检出。所有时间点牛乳中酮洛芬质量分数的实测结果均低于加拿大规定的最高残留限量50μg/kg,建议弃乳期为0 d。

Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.     

再论公安工作与群众路线

坚持和贯彻群众路线是公安机关的优良传统和特色。在新世纪新形势下,公安机关必须继承和发展群众路线,解放思想,与时俱进,不断创新群众路线,从而更加有效地发挥职能作用。     

How mass media attract political elites’ attention

Political agenda‐setting research has shown that policy makers are responsive vis‐à‐vis media priorities. However, the mechanisms behind this effect have remained understudied so far. In particular, agenda‐setting scholars have difficulties determining to what extent politicians react to media coverage purely because of the information it contains (information effect), and to what extent the effect is driven not by what the media say but by the fact that certain information is in the media (media channel effect), which is valued for its own sake – for instance, because media coverage is considered to be a reflection of public opinion. By means of a survey‐embedded experiment with Belgian, Canadian and Israeli political elites (N = 410), this study tests whether the mere fact that an issue is covered by the news media causes politicians to pay attention to this issue. It shows that a piece of information gets more attention from politicians when it comes via the media rather than an identical piece of information coming via a personal e‐mail. This effect occurs largely across the board: it is not dependent on individual politician characteristics.     

Employee Satisfaction With Work‐life Balance Policies And Organizational Commitment: A Philippine Study

This study investigates the relationship between public employees' satisfaction with work‐life balance policies (WLBPs) and organizational commitment in the relatively unexplored Philippine context. Our findings show that (i) employees' overall satisfaction with WLBPs is positively related to organizational commitment, (ii) when specific WLBPs are examined, only satisfaction with health and wellness programs are positively associated with organizational commitment, and (iii) when accounting for employees' preferences for WLBPs, compensatory time‐off, childcare policy, health insurance benefits, and paid sick leave are positively related to organizational commitment. The findings indicate that understanding which WLBPs employees prefer is important before implementing WLBPs. The article discusses the theoretical and practical implications of this study in the developing country context. Copyright © 2017 John Wiley & Sons, Ltd.     

论网络“人肉搜索”在侦查工作中的运用

网络人肉搜索是在现代信息科技手段的辅助下,人工参与并提纯信息的一种新兴信息获取方式。实践证明,人肉搜索强大的搜索能力有助于侦查部门查明犯罪嫌疑人身份、锁定犯罪嫌疑人位置、扩大破案线索、查明尸源。人肉搜索在侦查中的运用,是网络时代侦查破案的新途径,是侦查工作群众路线的新形式。在侦查工作中,人肉搜索的运用应当作为一种最后手段,在运用的范围、条件和程序上进行严格控制,在运用方法上要科学合理,兴其利而除其弊,合法地为侦查破案服务。     

群体性事件临战处置的战术探讨

群体性事件之所以难以处置,不仅在于群体性事件发生的原因杂、涉及广、人数众、局面乱,还在于指导公安机关处置群体性事件的意见和规定或过于抽象,或过于笼统,缺少适应性和操作性,跟不上治安形势的发展。尽管在群体性事件的临战处置中,警察的职责任务、警力调动、处置措施都有相应的规定,但目前从警察临战战术的层面进一步研究群体性事件的处置程序和方法,使之更具有操作性和针对性,仍是公安理论研究的一项迫切任务。
