Exploitation of the Ultraviolet Properties and Machine Cut Edges of Paper to Associate and Sequence Sheets in a Ream

Previously unreported line patterns visible under ultraviolet light were observed on a proportion of plain white A4 printer/copier paper from different manufacturers. These Ultraviolet Line Patterns (UVLPs) usually appear as stripes down the vertical length of the paper. Typically, the UVLPs were found to “repeat” through the ream in a predictable way, while also changing. It is postulated that the repeating nature of the UVLPs is a result of the way that paper is manufactured. This leads to the ability to sequence the sheets compared to their original source paper. Even in the absence of UVLPs, it is possible to use our observation of the manufacturing process to anticipate the order of several sheets of paper and conclusively associate them, in some cases, by physically fitting their machine cut edges and crossing paper fibers. Such a novel approach to examining questioned documents would be highly useful in forensic casework.     

Internal reliability and construct validity of the Novaco Anger Scale-1998-S in a sample of violent prison inmates in Sweden

Abstract

In this study, the internal reliability and construct validity of the recently adapted Swedish version of the Novaco Anger Scale (NAS-1998-S; Lindqvist, Dåderman, & Hellström, Social Behavior and Personality, 8, 773–788, 2003), as well as its scale correlations with demographic and criminality variables, were investigated. Construct validity was established by assessing the correlation pattern of the scales of NAS-1998-S with concurrent scales of similar and distinct constructs. Ninety-five male violent prisoners, ranging in age from 18 to 67 years, participated. The results demonstrated good internal reliability, consistent intrascale relationships, and appropriate construct validity of NAS-1998-S. The number of previous convictions had a moderate negative relationship with the capacity of control. Age and education correlated negatively with the NAS-1998-S scales, except Regulation. In addition to psychometric issues, the results were discussed from a clinical perspective on the offender population.     

IS BEING “SPIRITUAL” ENOUGH WITHOUT BEING RELIGIOUS? A STUDY OF VIOLENT AND PROPERTY CRIMES AMONG EMERGING ADULTS

Although prior research has had a tendency to confirm a negative association between religiousness and crime, criminologists have been slow to incorporate new concepts and emergent issues from the scientific study of religion into their own research. The self‐identity phrase “spiritual but not religious” is one of them, which has been increasingly used by individuals who claim to be “spiritual” but disassociate themselves from organized religion. This study first examines differences in crime between “spiritual‐but‐not‐religious” individuals and their “religious‐and‐spiritual,” “religious‐but‐not‐spiritual,” and “neither‐religious‐nor‐spiritual” peers in emerging adulthood. Specifically, we hypothesize that the spiritual‐but‐not‐religious young adults are more prone to crime than their “religious” counterparts, while expecting them to be different from the “neither” group without specifying whether they are more or less crime prone. Second, the expected group differences in crime are hypothesized to be explained by the microcriminological theories of self‐control, social bonding, and general strain. Latent‐variable structural equation models were estimated separately for violent and property crimes using the third wave of the National Longitudinal Study of Adolescent Health. The overall results tend to provide a partial support for the hypotheses. Implications for criminology and future research are discussed.     

What Have We Learned from Columbine

Abstract

This study first examined a model of the predictors and mediators of both suicidal ideation and violent ideation, particularly since both types of ideation were highly correlated (r = .55) among our young adolescent participants. The variables in the model were those identified in media accounts of the histories of the 10 high-profile school shooting cases, and that have also been included in our earlier model of the predictors of suicidal ideation, which we expanded to include violent ideation. Perceptions of competence or adequacy and social support from peers and parents predicted two mediators in the model, an adjustment/depression composite (self-esteem, hope to hopelessness, and affect, along a continuum from cheerful to depressed) and anger-induced physical aggression. These variables, in turn, predicted both suicidal and violent ideation. Secondly, we examined adolescents' reactions to vignettes that described harassing events, at the hands of peers and teachers simulating the type of audience-observed ridicule experienced by the school shooters. We were particularly interested in the emotional reaction of humiliation, an effect that has received surprisingly little attention in the emotion literature. Humiliation was related to other emotions such as anger and depression, consistent with the co-occurrence of internalizing and externalizing symptoms demonstrated in the overall model. Next we compared those who reported that they would respond violently to the events in vignettes compared to those reporting nonviolent reactions. Examining the variables in the general model, those who reported violent ideation reported markedly lower perceptions of adequacy, lower levels of social support, lower self-esteem, greater hopelessness, depressed affect, and anger-induced aggression. The violent ideators also reported higher levels of both homicidal and suicidal ideation. Discussion focused on the fact that thoughts of violence toward others as well as toward the self have similar psychosocial origins that should be considered in prevention and intervention efforts.     

When do politicians listen to lobbyists (and who benefits when they do)?

This article provides an empirical test of an informational model of lobbying. The model predicts when lobbyists provide useful information to policy makers and when policy makers follow lobbyists' advice. The predictions are assessed against data on the policy positions and lobbying activities of firms and other organised groups in the context of 28 policy proposals advanced by United Kingdom governments between 2001 and 2007. The results suggest that the interactions between policy makers and lobbyists are driven mainly by the expected policy costs for policy makers, providing lobbyists with strong incentives to provide correct advice to policy makers. There is little support for the expectation that lobbyists can successfully persuade policy makers to take a course of action that is beneficial to the lobbyist at the expense of wider constituencies.     

Radical distinctions: a comparative study of two jihadist speeches

Work on contemporary instances of “violent extremist” texts tends to see these primarily as more or less instrumental extensions of political (or political-religious) movements. As a result, there are few studies that devote close attention to individual examples of the texts themselves. In this article, we offer a detailed analysis of two jihadist speeches by the prominent ideologues Adam Gadahn and the late Anwar al-Awlaki. We argue that Al-Awlaki’s work ultimately succeeds where Gadahn’s seemingly fails because it is underpinned by a form of fundamentalism which, paradoxically, is inherently premised on the survival of possibilities for dialogue and polyglossia.     

A New Look at the Gender Gap in Offending

Studies of public support for capital punishment have consistently observed a strong and enduring gender gap in the level of death penalty support, with males consistently more inclined than females to support capital punishment. This unexplained relationship has endured over time and space as well as across a myriad of research designs. The present study uses attribution theory in a factorial survey design to account for this relationship. Analyses of data obtained from jurors provide mixed support for attribution theory yet fails to bridge the gender gap in death penalty support. The implications of these findings as they relate to gender, socialization, and attributions are discussed.

论侦查假设在视频图像侦查中的运用

在信息化背景下,视频图像侦查已经成为刑侦部门打击和预防犯罪的重要方法之一。在视频图像侦查中,侦查人员针对采集的视频图像信息运用侦查假设的方法进行研判分析,挖掘出侦查线索,化解侦查僵局,切实推进侦查工作的进程。因此,有必要以大量视频图像侦查成功案例为素材,系统地对侦查假设在视频图像侦查中运用的工作流程进行梳理和总结,从人、案情、通信工具、交通工具、现场痕迹物证和光影六个方面提出假设并验证假设。     

论暴力恐怖事件发生后社会心理氛围的调控

恐怖犯罪的发生与特定的政治经济环境、国际形势、历史遗留问题等多种因素有关。反恐怖策略固然需要重视对暴力恐怖犯罪的打击,但更要重视营造健康的社会心理氛围,降低既定的社会环境对个体的消极影响,从一般预防的层面减少恐怖犯罪发生的机率。暴力恐怖事件发生后社会心理氛围的调控要注意反恐宣传、社会控制与心理引导等问题。
