涉警突发敏感事件网络舆论引导

在网络技术快速发展的今天,网络媒体在信息发布的领域不再一者独大,自媒体对网络舆论的发展起着极大的催化推动作用。涉警突发敏感事件的网络舆论,具有网络舆论主体多元化、匿名性,形成高速性,传播互动性、互文性的特点。由于警察的特殊身份,涉警突发敏感事件网络舆论的内容往往较为敏感,部分网民的观点容易夹杂着宣泄的心理,负面影响较大。针对涉警敏感事件网络舆论的独特之处,在涉警突发敏感事件发生之后,公安机关在舆论引导的过程中应着重把握"快"、"准"、"狠"三大原则和策略;找准时机进行议题的设置与置换;发挥网络舆论领袖的重要作用;建立一支专业的网络技术队伍,对涉警突发敏感事件网络舆论进行技术引导。

The potential of artificial aging for modelling of natural aging processes of ballpoint ink

Artificial aging has been used to reproduce natural aging processes in an accelerated pace. Questioned documents were exposed to light or high temperature in a well-defined manner in order to simulate an increased age. This may be used to study the aging processes or to date documents by reproducing their aging curve. Ink was studied especially because it is deposited on the paper when a document, such as a contract, is produced. Once on the paper, aging processes start through degradation of dyes, solvents drying and resins polymerisation. Modelling of dye's and solvent's aging was attempted. These processes, however, follow complex pathways, influenced by many factors which can be classified as three major groups: ink composition, paper type and storage conditions. The influence of these factors is such that different aging states can be obtained for an identical point in time. Storage conditions in particular are difficult to simulate, as they are dependent on environmental conditions (e.g. intensity and dose of light, temperature, air flow, humidity) and cannot be controlled in the natural aging of questioned documents. The problem therefore lies more in the variety of different conditions a questioned document might be exposed to during its natural aging, rather than in the simulation of such conditions in the laboratory. Nevertheless, a precise modelling of natural aging curves based on artificial aging curves is obtained when performed on the same paper and ink. A standard model for aging processes of ink on paper is therefore presented that is based on a fit of aging curves to a power law of solvent concentrations as a function of time. A mathematical transformation of artificial aging curves into modelled natural aging curves results in excellent overlap with data from real natural aging processes.     

Issues in Conducting Research on Crime Victimization

Abstract

There are many issues facing the non-Indian researcher who works with Native American subjects in Indian country. The impact of historical trauma, the history of Native American/United States government relations, and a history of exploitation are just some of the concerns facing non-Indian researchers. It is possible for non-Indian researchers to overcome tribal skepticism and resistance through the inclusion of tribal members in research design and implementation, cooperation with tribal research internal review boards, and respecting tribal values and beliefs. Native communities, as a result of past exploitation, may need reassurance that the research project will result in meaningful change or the development of resources in return for their participation.     

Identification of Carbonates as Additives in Pressure‐Sensitive Adhesive Tape Substrate with Fourier Transform Infrared Spectroscopy (FTIR) and Its Application in Three Explosive Cases

Abstract: Pressure‐sensitive tape is often used to bind explosive devices. It can become important trace evidence in many cases. Three types of calcium carbonate (heavy, light, and active CaCO₃), which were widely used as additives in pressure‐sensitive tape substrate, were analyzed with Fourier transform infrared spectroscopy (FTIR) in this study. A Spectrum GX 2000 system with a diamond anvil cell and a deuterated triglycine sulfate detector was employed for IR observation. Background was subtracted for every measurement, and triplicate tests were performed. Differences in positions of main peaks and the corresponding functional groups were investigated. Heavy CaCO₃ could be identified from the two absorptions near 873 and 855/cm, while light CaCO₃ only has one peak near 873/cm because of the low content of aragonite. Active CaCO₃ could be identified from the absorptions in the 2800–2900/cm region because of the existence of organic compounds. Tiny but indicative changes in the 878–853/cm region were found in the spectra of CaCO₃ with different content of aragonite and calcite. CaCO₃ in pressure‐sensitive tape, which cannot be differentiated by scanning electron microscope/energy dispersive X‐ray spectrometer and thermal analysis, can be easily identified using FTIR. The findings were successfully applied to three specific explosive cases and would be helpful in finding the possible source of explosive devices in future cases.     

慢性脱氧麻黄素染毒大鼠心肌中热休克蛋白的免疫组织化学研究

本文对慢性脱氧麻黄素（MethamphetamineMeth；1mg／kg／day2—8周）染毒大鼠心肌中热休克蛋白的代表物HeatshockProtein70（HSP70）和Ubiquitin进行了免疫组织化学的研究。实验结果显示早期Meth染毒阶段（2周组），虽然心肌组织未出现明显的病理形态学变化，但在心肌细胞、心内膜上皮细胞、血管平滑肌细胞和毛细血管内皮细胞内均可检出HSP70和Ubiqui－tin。以后随着染毒时间的延长，HSP70和Ubiquitin在细胞内的表达也增强。而对照组大鼠心肌组织在实验期间缺乏明显的表达。这些发现提示在受到Meth作用时，HSP70和Ubiquitin在心肌细胞内的表达优先于病理形态学改变的出现。且石蜡组织切片中热休克蛋白的免疫组织化学研究是早期诊断心肌细胞损伤的一个良好方法。
