1H‐NMR with Multivariate Analysis for Automobile Lubricant Comparison

Identification of suspected automobile‐related lubricants could provide valuable information in forensic cases. We examined that automobile lubricants might exhibit the chemometric characteristics to their individual usages. To compare the degree of clustering in the plots, we co‐plotted general industrial oils that were highly dissimilar with automobile lubricants in additive compositions. ¹H‐NMR spectroscopy was used with multivariate statistics as a tool for grouping, clustering, and identification of automobile lubricants in laboratory conditions. We analyzed automobile lubricants including automobile engine oils, automobile transmission oils, automobile gear oils, and motorcycle oils. In contrast to the general industrial oils, automobile lubricants showed relatively high tendencies of clustering to their usages. Our pilot study demonstrated that the comparison of known and questioned samples to their usages might be possible in forensic fields.     

Lone‐actor Terrorism and Impulsivity

In some recent cases of lone‐actor terrorism, there is evidence the subject acted impulsively, often in response to a triggering event which contained a loss and humiliation. Evidence suggests the subjects acted precipitously, despite planning and preparation carried out in the preceding weeks or months, and their attacks failed to include the often considerable preparation that had been done. The pathway became a runway. The authors recommend the traditional assessment of impulsivity in persons of concern for lone acts of terrorism, as well as other proximal warning behaviors for targeted violence. Both indirect and direct assessment guidelines are proposed, with an emphasis upon self‐report, psychological testing, collateral data gathering, and historical records.     

Think global,talk local: getting the party political message across in the age of the internet

This paper seeks to test the view that the Internet will provide politicians and political parties with a means of directly communicating with electors, so circumnavigating the perceived bias of the mass media, and explores how the political use of the Internet will impact on campaigning, particularly at the local/personal level. The evidence surveyed shows that political use of the Internet is, despite the hype, still in its infancy, but that more extensive use will lead to changes in the style and mode of political communications. The Internet will eventually enable politicians and parties to address a mass audience in qualitative new ways, tailoring their message and information dissemination to individual and local concerns. But this will bring all the consequences of direct communication, such as increased workloads and the danger of atomising the political process. Politicians and parties may hanker for the days when the traditional mass media intervened in the process of political communications. This paper is an edited version of the one presented to 'On Message: A Conference on Political Communication and Marketing sponsored by the Political Studies Association Media and Politics Group, Loughborough University, September 2000.

浅论公安机关应对群体性事件的群众工作

我国群体性事件基本属于人民内部矛盾。群众工作是我党解决人民内部矛盾的主要方法,公安机关在处置群体性事件中要树立群众路线的观念,把群众工作作为解决群体性事件的首选途径和方法。     

Inventing terrorists: the nexus of intelligence and Islamophobia

The transatlantic Islamophobia industry, emboldened by US intelligence efforts to entrap Muslims, appears to have helped to increase permissible levels of Islamophobia across the US, as illustrated by the fiery anti-Muslim rhetoric during the 2016 presidential campaign. In this article, I first look at five key leaders of the Islamophobia industry who also claim to be “terrorism experts” and have links to US and Israeli intelligence. I then describe US law enforcement’s mass surveillance of Muslims and its invention of terrorists, including a map of the “successful terrorist prosecutions” claimed by the US Department of Justice, most of which were tried only as criminal cases. Finally, I explore in-depth the case against the Holy Land Foundation, a Muslim charity based in Texas that was run by Palestinian-Americans and targeted by both the state and the Islamophobia industry for its dubious links to “terrorism”, helping to legitimate the Bush W. Administration’s “War on Terror”. I argue that this nexus of intelligence and Islamophobia has empowered anti-Muslim voices that were formerly marginal.     

处置群体性事件若干问题分析

文章阐释了我国九十年代以来群体性事件概念的演变,从处置群体性事件的基本依据和原则,处置群体性事件的基本理念,处置群体性事件的基本技战术,以及慎用警力、慎用警械、慎用强制措施等方面分析了当前群体性事件处置中存在的相关问题。     

如何处置群体性事件

群体性：事件处置不当,将给社会稳定带来严重危害。群体性事件的发生机制与燃烧的机制一样：一是被歧视、被不公正对待的社会阶层（或群体、集团）的愤怒或挫折感的积累（即燃料的形成）;二是激发群体性事件的意外事件或谣言（即火种）。群体性事件处置的第一个重要原则是预防,即防止罢工抗议人群情绪失控、防止人群中出现暴力违法行为;第二个重要原则就是在抗议罢工人群出现暴力甚至与警察冲突时,要采取“擒贼擒王”、“网开一面”的原则。     

The Identification of a Steel Mold’s Marks on Fake Drug Bottles

Plastic bottles are commonly encountered in drug cases where they are used as packaging materials and produced with polymers. However, to the best of our knowledge, systematic studies on the evidential values of medicine bottles have not been carried out. Therefore, it is difficult practically to determine if it is possible to identify whether the plastic bottles are manufactured with the same steel mold by comparing the manufacturing marks on plastic bottles. This paper reports the successful attempt of the authors in establishing a definite relationship between three different medicine bottles with a steel mold recovered from suspects. Fourier transform infrared spectroscopy (FT-IR) was used to characterize the chemical composition of submitted medicine bottles, and then some physical characteristics (viz., total length, length, and diameter of different parts) and the manufactured marks on these bottles were examined. The results showed that the linkage of the medicine bottles to a steel mold was successfully established using the similarities in physical characteristics and manufacturing marks. In the process, the FT-IR was only complementary in the identification process. The individual characteristics of plastic medicine bottles included the imperfections and striated impressions that were produced by the grinding patterns on the inner surface of a steel mold.     

Detection of Pb,Ba, and Sb in Cadaveric Maggots and Pupae by ICP-MS*

The concentrations of lead (Pb), barium (Ba), and antimony (Sb), characteristic of GSR, were determined in soil sediments and immature (larvae) of cadaveric flies of the family Calliphoridae, by inductively coupled plasma mass spectrometry (ICP-MS). This research refers to a case study from two real crime scenes in which the corpses were in an advanced state of decomposition. In case 1, the victim had holes similar to gunshot wounds, and in case 2, there was no evidence of perforations in the corpse. Soil sediment collection was performed at three different points of the terrain, at a minimum distance of 10 m from the corpse, for cases 1 and 2. In relation to the collection of immatures, larvae were collected in regions of the mouth, nose, and orifices similar to the entry of firearms projectile into the body, for case 1, and collection of larvae and pupae, located on the body and underneath it, for case 2. It was possible to detect and quantify the three elements of interest (Pb, Ba, and Sb) by ICP-MS in both sediment and cadaveric larvae. Concentrations of 4.44, 8.74, and 0.08 μg/g were obtained for Pb, Ba, and Sb, respectively, in the soil for case 1. For the case 2, the concentrations in Pb, Ba, and Sb were from 16.34 to 26.02 μg/g; from 32.64 to 57.97 μg/g and from 0.042 to 0.30 μg/g, respectively. In the larvae, Pb, Ba, and Sb were quantified in cases 1 and 2 with a concentration of 6.28 and 1.78 μg/g for Pb, 1.49 and 2.94 μg/g for Ba, 0.50 μg/g and <LD for Sb, respectively. These new results present the detection of characteristic elements of GSR in cadaveric larvae in humans in a real crime scene, besides highlighting the importance of the study of immature flies, using the ICP-MS technique in forensic analysis.
