Area characteristics and regional variates as determinants of area property crime levels

This article seeks to examine the area characteristics that act as determinants of area property crime levels, namely, incidence and prevalence. The crime figures are extracted from the 1984 British Crime Survey. Area characteristics are taken from the 1981 UK census. Initial exploratory analysis considers the non-Gaussian nature of the crime data, the statistical implications of this, and the transformations used to overcome these problems. In addition, possible regional and inner-city/non-inner-city variations are considered. The later stages move from simple individual correlations to multiple regression models. Three regression models are considered and the reasons for refining these are explored, with the results indicating that both area characteristics and regional influences play a role as determinants of the area crime level. In particular, population density and the area population age profile have significant roles to play. The conclusions support the recent revival of the application of ecological concepts in the analysis of crime levels.     

What sort of future for critical criminology?

This article argues for a criticalcriminology that is more mindful of the growing number ofcritiques of its general epistemologicaldirection. Specifically, such criticismtakes issue with the continued emphasis incritical criminology on crime and penalty,often to the detriment of a moreencompassing focus on issues associatedwith ``social harm'. In an attempt tohighlight the current weaknesses ofcritical criminology attention is drawn toa small although revealing conference thattook place at the University of WesternSydney in February 2001. In contrast to thenarrow concerns demonstrated at thisconference the article calls for a moreexpansive approach to the study of crimeand penalty that falls under thezemiological umbrella of social harm andwhich takes account of social movements andother disciplines that have givenrecognition to the question of humanrights. Such a call derives from StanCohen's evocation of the ``voracious Gods'that must be sated if a progressive andrelevant critical criminology is to bedeveloped in an era of rapid socio-economicand political transformation.     

Application of mRNA Expression Analysis to Human Blood Identification in Degenerated Samples that were False‐negative by Immunochromatography,,

Forensic laboratories are often faced with cases in which methamphetamine hydrochloride‐mixed blood is unable to be identified as human blood by immunochromatography against human hemoglobin A0. The application of mRNA expression analysis to samples that showed a false‐negative with immunochromatography was investigated as an alternative approach that did not depend on the antigen–antibody reaction. Real‐time PCR was used to examine the expression levels of blood markers such as glycophorin A, spectrin beta, and hemoglobin beta. Hemoglobin beta was the only marker that was specifically detected in blood, while glycophorin A was useful for determining human specificity. Hemoglobin beta showed good detection sensitivity and was detectable in 37‐year‐old blood stains. Hemoglobin beta was exclusively detectable in methamphetamine hydrochloride‐mixed blood stains. Detergents and disinfectants did not significantly influence mRNA markers. The proposed mRNA expression analysis was suitable for human blood identification as an alternative method to immunochromatography.     

Parliamentary Question Times: How Legislative Accountability Mechanisms Affect Mass Political Engagement

Over time, people have been losing interest in politics. Some believe this to be one of the largest challenges facing democracy today. What causes some citizens to be more engaged than others? This paper argues that national-level political institutions are important in shaping the tone of political debate between election campaigns. Some countries have regular, accessible debates between political leaders; in others the debate is rarer and harder to follow. Parliamentary question time (QT) is a prominent forum for regular elite-level debate, and QTs featuring open, accessible debate should help induce citizens to engage with politics by providing them with an information-laden political spectacle. The data show that these open QTs are associated with higher levels of political knowledge, partisanship, and turnout.     

Objective Evaluation of Subclass Characteristics on Breech Face Marks

Subclass characteristics can be found on the breech face marks left on spent cartridge cases. Even if they are assumed to be rare and their reported number is small, they can potentially lead to false associations. Subclass characteristics have been studied empirically allowing examiners to recognize them and to understand in which conditions they are produced. Until now, however, their influence on the identification process has not been studied from a probabilistic point of view. In this study, we aim at measuring the effect of these features on the strength of association derived from examinations involving subclass characteristics. The study takes advantage of a 3D automatic comparison system allowing the calculation of likelihood ratios (LRs). The similarities between cartridge case specimens fired by thirteen S&W .40S&W Sigma pistols are quantified, and their respective LRs are computed. The results show that the influence of subclass characteristics on the LRs is limited, even when these features are prevalent among the potential sources considered in a case. We show that the proportion of firearms sharing subclass characteristics should be larger than 40% of the pool of potential firearms for the effect to be significant.     

Driving racial profiling research forward: Learning lessons from sentencing research

Discretion is an integral component of the criminal justice system and is exercised by both police and the judiciary. Based on the extant research, evidence of racial/ethnic disparities within the context of traffic stops and sentencing decisions has been documented. Due to its long history of inquiry, sentencing research has developed a more thorough understanding of disparity and its correlates. This article contends that racial profiling research could expedite its development by learning from the history of sentencing research. Specifically, the extant research on sentencing decisions has demonstrated the value and utility of theory and methods as pillars of knowledge development. Therefore, progress in racial profiling research is most likely accomplished by employing similar theoretical frameworks and appropriate quantitative and qualitative approaches.
