Firing distance estimates with pellet dispersion from shotgun with various chokes: an experimental, comparative study

There are several studies suggesting models for firing distance estimation due to pellet dispersion, but few of them consider the degree of choke of a shotgun. The purpose of this research is to suggest some models for estimation of the firing distance for choked and cylinder bore shotguns. Twelve gauge with full chokes, and 12 and 16 gauge with cylinder bore shotguns were fired with #2 and #5 shots from 75, 100, 300, 500, and 1000 cm distances. Statistically significant pellet dispersion values were found for each shotgun by using #2 and #5 shots for different firing distances. All the data obtained were analyzed with linear regression and four models were constituted. Investigators should use special formulae for each shotgun, degree of choke, and pellet type while determining the firing distance. Therefore, more experimental and comparative studies should be designed for each type.

Sequential angulation,spatial dispersion and consistency of distance attack patterns from home in serial murder,rape and burglary

Abstract

Three related measures of spatial movement (sequential angulation, spatial dispersion and consistency of distance in attack target) were compared across three serial offence types: serial homicide (n=35), serial rape (n=41) and serial burglary (n=30). In each case, each offender had committed at least five offences. “Spatial dispersion”, defined as the extent to which an offender distributes his offences across either a focused or relatively more evenly distributed area, revealed that burglary was less evenly distributed (i.e. more focused) than rape and murder. “Sequential angulation”, defined as the degree of rotational movement around the home of the offender from one offence to the next, revealed that serial murderers have higher angulation scores than do rapists who, in turn, have higher angulation scores than burglars. Lastly, a comparison of the offender's consistency in the relative distance travelled from home to each attack site (“consistency of distance in attack target”) was relatively similar across the three groups. This was despite the comparison of different serial offence types from disparate geographical areas. The supposition that differences in dispersion and sequential angulation scores across crime types are related to the perceived risk of the crime has been confirmed. The specificity and the mobility of the targets are also discussed.     

多元文化视阈下大学生先进典型培育的价值意蕴

大学生先进典型是大学生群体的优秀代表,是传统美德、时代精神和社会主义核心价值观的集中体现,是大学生学习借鉴的楷模。多元文化时代,大学生价值取向呈现个性化、易变化、物质化、功利化等多样性特点,大学生先进典型的影响力日渐式微。高校理应充分认识大学生先进典型的培育对大学生成长成才的导向、示范和激励等价值,狠抓大学生先进典型的选树、培养和宣传工作,以期形成大学生学习先进典型、争当先进典型的浓厚校园文化氛围。     

廉政文化建设融入同城高校大学生思想政治教育的思考

廉政文化建设融入同城高校大学生思想政治教育,必须充分认识在同城高校开展廉政文化建设的重要意义、基本思路和有效途径。加强廉政文化建设,开展同城高校大学生廉洁教育,是高校加强和改进大学生思想政治教育的重要任务,是建立健全党风廉政建设和反腐败工作长效机制的必然要求。     

思想政治工作对意识群体性分流的介入

加入WTO,标志着我国社会主义市场经济发展的一个新阶段,政府干预的减少及外来文化的影响,将在社会上引起广泛的意识群体性分流.政治参与意识、国家民族认同意识、社会角色认同意识以及人际融合意识的分流,要求思想政治工作积极介入,更新观念,转换思维,整合文化,以保障社会稳定.     

美国多元主义政体成因探析

美国的政治过程是由一批权力中心的运作来体现的美国是典型的多元主义政体国家，这一强调个人和公民社会权利的政治体制表现为权力中心的多元化。多元主义政体在美国的形成不是偶然的，而是由美国独特的历史背景、自由主义的政治哲学、人们对纯粹民主政治可能导致弊端的担心以及美国利益多元化等多方面因素决定的。了解美国政治本质特征及其成因，有助于我们认识美国政治和美国政府的决策过程。     

Blind Spots: The Effects of Information and Stakes on Fairness Bias and Dispersion

Mounting empirical research provides evidence of fairness bias and its economic and social effects, where fairness bias refers here to a deviation of claims from unbiased justice due to a personal stake. A far less appreciated issue is dispersion of fairness views and claims, which is also important for its effects on disagreements, empirical analysis, and philosophical theories. This study undertakes a systematic analysis of the effects on fairness bias and dispersion of two variables: stakes and information. Most philosophical and social science analyses related to justice and bias associate heightened bias with increased information and, conversely, impartiality with the elimination of certain information. Less attention has been paid to the opposing impact of information, which is to supply the facts needed to achieve justice more reliably. An important open question is whether, on balance, increased information helps agents to achieve fairer outcomes or whether biased use of such information contributes to less fair outcomes. This study focuses on a set of previously reported experiments that share certain features and subjects them to a new analysis. The results of this analysis suggest that, although information is often used in a self-serving way, increased information can, under certain conditions, contribute to fairness claims becoming less biased and less dispersed, both for stakeholders as well as impartial spectators.

对新时期做好边检队伍思想政治工作的思考

转制以来,上海边检队伍的思想政治工作按照“政治建警、制度管警、科教强警、从优待警”的工作思路,有力地推进了上海边检工作的开展。但我们也应清醒地看到在思想政治工作方面存在的差距,找出存在问题的原因,加强思想政治教育,正确处理好四种关系。只有这样,新时期边检思想政治工作才会有生命力。
