论群体性事件处置中的说服艺术

群体性事件基本上属于人民内部矛盾.因此,公安机关在处置过程中.应最大限度地运用解决人民内部矛盾的方法和手段.群体性事件处置中说服的条件是事件态势处于相对控制之下,说服的原则主要有平等性原则、针对性原则、可信性原则和感染性原则.说服方法有标签效应法、"自己人"效应法、亲情效应法和威信效应法等.     

The Implications of Framing Effects for Citizen Competence

Social scientists have documented framing effects in a wide range of contexts, including surveys, experiments, and actual political campaigns. Many view work on framing effects as evidence of citizen incompetence—that is, evidence that citizens base their preferences on arbitrary information and/or are subject to extensive elite manipulation. Yet, we continue to lack a consensus on what a framing effect is as well as an understanding of how and when framing effects occur. In this article, I examine (1) the different ways that scholars have employed the concepts of framing and framing effects, (2) how framing effects may violate some basic criteria of citizen competence, and (3) what we know about how and when framing effects work. I conclude that while the evidence to date suggests some isolated cases of incompetence, the more general message is that citizens use frames in a competent and well-reasoned manner.     

大众化教育背景下校园文化创新研究

高等教育大众化对校园文化建设提出了新的要求。大众化教育背景下,校园文化建设应把握好主体性设计、群众性参与性和综合性评价原则,推行项目化运作,尤其是要抓好学生社团、网络和社会实践这三个载体,同时要建管协调,堵疏结合,牢牢把握校园文化建设的主动权,充分发挥校园文化的育人功能,推动校园文化健康发展。     

论爆炸现场的救援和身份认证——以恐怖主义爆炸袭击为背景

恐怖主义是威胁当今世界和平的一个重要因素,目前恐怖活动在全球有愈演愈烈的趋势;我国在新世纪也同样面临恐怖袭击的威胁。爆炸手段是恐怖分子发动袭击的主要手段,爆炸现场的救援和身份认证是各国应对恐怖袭击的难题。本文介绍了恐怖主义爆炸案件的概念,分析了恐怖主义爆炸袭击常用的手段和现场的特点,借鉴以色列的经验,论述了现场救援和身份认证的程序和步骤。

Identification of Eight Synthetic Cannabinoids,Including 5F‐AKB48 in Seized Herbal Products Using DART‐TOF‐MS and LC‐QTOF‐MS as Nontargeted Screening Methods

Synthetic cannabinoids are sprayed onto plant material and smoked for their marijuana‐like effects. Clandestine manufacturers modify synthetic cannabinoid structures by creating closely related analogs. Forensic laboratories are tasked with detection of these analog compounds, but targeted analytical methods are often thwarted by the structural modifications. Here, direct analysis in real time coupled to accurate mass time‐of‐flight mass spectrometry (DART‐TOF‐MS) in combination with liquid chromatography quadruple time‐of‐flight mass spectrometry (LC‐QTOF‐MS) are presented as a screening and nontargeted confirmation method, respectively. Methanol extracts of herbal material were run using both methods. Spectral data from four different herbal products were evaluated by comparing fragmentation pattern, accurate mass and retention time to available reference standards. JWH‐018, JWH‐019, AM2201, JWH‐122, 5F‐AKB48, AKB48‐N‐(4‐pentenyl) analog, UR144, and XLR11 were identified in the products. Results demonstrate that DART‐TOF‐MS affords a useful approach for rapid screening of herbal products for the presence and identification of synthetic cannabinoids.
