Improved Area of Origin Estimation for Bloodstain Pattern Analysis Using 3D Scanning

An important component of crime scene reconstruction is bloodstain pattern analysis (BPA). Where BPA concerns impact patterns, estimating the area of origin is critical information for scene reconstruction. Traditionally, this is achieved by measuring individual bloodstains and performing trigonometric calculations; however, 3D scanning has been proposed as a viable alternative for overcoming logistical and practical concerns with the manual method. Therefore, this project aimed to establish whether the FARO Focus 3D scanner and FARO Zone 3D software can improve the accuracy of area of origin estimates relative to the manual method. We created a series of eight bloodstain impact patterns and performed paired analysis using the two methods to estimate areas of origin for each pattern. Our data suggested that FARO-derived estimates were generally more accurate than using the manual method. FARO-estimated heights of origin areas were generally closer to the true distance. Both methods underestimated the distance from the wall for most patterns originating 150mm or greater from the wall, but overestimated distances for patterns originating closer to the wall. The degree to which distances were underestimated increased significantly the further the blood source was from the wall and was greater for FARO-derived estimates. The results of this research contribute to the validation of these instruments for operational implementation for BPA and should be considered alongside the practical benefits of 3D scanning relative to manual methods. Further, 3D scanning can provide reliable BPA reconstruction documentation for technical review and court presentation.     

Domestic labour,masculinity and social change: insights from working-class young men’s transitions to adulthood

Abstract

Drawing on a seven-year longitudinal qualitative study in England, this paper presents evidence of how engagement with housework and childcare is regular and normalized for contemporary working-class young adult men. I explain this development with reference to inclusive masculinity theory, but supplement this by incorporating Mannheim’s concept of social generation, as recently adopted by scholars of youth sociology. The paper thus further augments other research that has documented considerable change in the construction and performance of contemporary masculinities – such as an opening up of gendered behaviours and a decrease (but not erasure) of homophobia – among young men across multiple contexts in English-speaking countries.     

The Past as Prologue in Life Extension

Aging research may significantly lengthen human life spans in the foreseeable future. This paper argues that we do not need to wait until this happens to prepare for the dislocations that may result. Increased longevity over the past century has already raised urgent, unresolved issues of equity, social cohesion, and human dignity. These developments, and our past experiences in dealing with them, provide a basis for revisiting the basic questions raised by all attempts to extend human life: what does life mean, and why is it worth extending?     

The Public Service Mutual: Theories of Motivational Advantage

Public service mutuals are a form of employee‐led organization in which service workers spin out of the public sector to form “mutuals” that contract back with government to provide a service. This article draws on economic and psychological theory to demonstrate that mutuals can align both self‐interested and altruistic or public service motivations so as to serve the social good; moreover, by offering greater autonomy to public service professionals, mutuals are predicted to encourage energetic and persistent behaviors. In both cases, there is an advantage over alternative forms of organization such as the public sector bureaucracy, the shareholder‐owned private firm, or the nonprofit organization. The employee‐led mutual form, however, may not appeal to risk‐averse workers, its collective decision‐making systems may be inefficient, and external mechanisms may be required to ensure that organizational outcomes are always directed toward the social good.     

Non-Suicidal Self-Injury and Depressive Symptoms During Middle Adolescence: A Longitudinal Analysis

Previous research has shown a consistent positive association between non-suicidal self-injury and depressive symptoms. However, the direction of the effects has not been examined. To understand whether non-suicidal self-injury predicts depressive symptoms or vice versa, we examined the relations between non-suicidal self-injury and depressive symptoms across three waves of self-report data collected 1 year apart from 506 Swedish adolescents (47 % girls; M age = 13.21; SD = .57) who were attending 7th grade at the onset of the study. The results suggest that depressive symptoms predict increases in non-suicidal self-injury 1 year later between the first and second waves of the study. Between the second and third waves of the study depressive symptoms and non-suicidal self-injury were significantly correlated indicating co-occurrence with no direction of effect rather than depressive symptoms predicting non-suicidal self-injury or vice versa. Group comparisons revealed no differences for boys and girls. The findings help clarify the relationships between non-suicidal self-injury and depressive symptoms during middle adolescence.     

A Comment on Kellogg's Analysis

An American specialist on the Soviet and Russian military-industrial complex examines the economic, social and political tensions within one of the most important, closed nuclear cities in Russia. Based on an intensive examination of the city's daily newspaper, not heretofore available in the West, the author explores the implications of the current situation for prospective nuclear accidents or proliferation.
