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.

Epidemiology of Suicide Attempts among Youth Transitioning to Adulthood

Suicide is the second leading cause of death for older adolescents and young adults. Although empirical literature has identified important risk factors of suicidal behavior, it is less understood if changes in risk factors correspond with changes in suicide risk. To address this knowledge gap, we assessed if there were different trajectories of suicidal behavior as youth transition into young adulthood and determined what time-varying risk factors predicted these trajectories. This study used four waves of data spanning approximately 13 years from the National Longitudinal Study of Adolescent Health. The sample included 9027 respondents who were 12–18 years old (M?=?15.26; SD?=?1.76) at Wave 1, 50% male, 17% Hispanic, and 58% White. The results indicated that 93.6% of the sample had a low likelihood for suicide attempts across time, 5.1% had an elevated likelihood of attempting suicide in adolescence but not young adulthood, and 1.3% had an elevated likelihood of attempting suicide during adolescence and adulthood. The likelihood of a suicide attempt corresponded with changes on depression, impulsivity, delinquency, alcohol problems, family and friend suicide history, and experience with partner violence. Determining how suicide risk changes as youth transition into young adulthood and what factors predict these changes can help prevent suicide. Interventions targeting these risk factors could lead to reductions in suicide attempts.     

‘Triple wins’ or ‘triple faults’? Analysing the equity implications of policy discourses on climate-smart agriculture (CSA)

This paper analyses contrasting discourses of ‘climate-smart agriculture’ (CSA) for their implications on control over and access to changing resources in agriculture. One of the principal areas of contestation around CSA relates to equity, including who wins and who loses, who is able to participate, and whose knowledge and perspectives count in the process. Yet to date, the equity implications of CSA remain an under-researched area. We apply an equity framework centred on procedure, distribution and recognition, to four different discourses. Depending on which discourses are mobilised, the analysis helps to illuminate: (1) how CSA may transfer the burden of responsibility for climate change mitigation to marginalised producers and resource managers (distributive equity); (2) how CSA discourses generally fail to confront entrenched power relations that may constrain or block the emergence of more ‘pro-poor’ forms of agricultural development, adaptation to climate change, or carbon sequestration and storage (procedural equity); (3) how CSA discourses can have tangible implications for the bargaining power of the poorest and most vulnerable groups (recognition). The paper contributes to work showing the need for deeper acknowledgement of the political nature of the transformations necessary to address the challenges caused by a changing climate for the agricultural sector.     

Configurations of Identity Among Sexual Minority Youth: Context,Desire, and Narrative

Youth with same-sex desire undergo a process of narrative engagement as they construct configurations of identity that provide meaning and coherence with available sexual taxonomies. This article presents a theoretical analysis and four case studies centering on the relationship among context, desire, and identity for youth with same-sex desire. Through an interpretive, holistic analysis of the personal narratives of youth, we examine the integration of same-sex desire, behavior, and identity in the general life story and the selective appropriation of elements of “master narratives” of sexual identity development. Narratives were characterized by challenges to integrate desire, behavior, and identity into a configuration that conformed to the received sexual taxonomy. Implications for theory and further research on sexual identity development are discussed.     

How the City of London lost at Brexit: a historical perspective

The nature of the City of London as an offshore financial centre has long made London dependent on the British state providing protection from external political regulation, even as London’s foreign currency business separated its interests from British governments’ economic policy preoccupations. Since the 2008 crash and the onset of the eurozone crisis, London has faced threats to both its autonomy from external regulatory demands and to its offshore business interests at the same time as the long-standing external statecraft of British governments around EU membership has broken down. The Cameron governments’ efforts to protect the City within the European Union under political conditions that were transformed by the eurozone crisis exposed the limits of Britain’s position as a member of the European Union. When David Cameron then tried to resolve the problem of EU membership through a referendum he made it extremely difficult to defend the City’s broader commercial interests in the Single European Market because freedom of movement issues weighed significantly more in British domestic politics than financial services.     

Repression and Monarchical Resilience in the Arab Gulf States

Why the uprisings that broke out across the Middle East and North Africa in 2010-11 ousted the leaders of republics but left monarchies largely intact remains puzzling. One promising explanation for the resilience of monarchical regimes argues that monarchs exercise repression in a comparatively restrained and largely effective fashion. Proponents of this theory tend to conflate two crucial causal factors: the level of state coercion exercised against opposition activists and the degree of indiscriminateness with which coercion is deployed. By treating these variables as analytically distinct, a more compelling explanation for monarchical resilience can be advanced. The advantages of the revised argument are illustrated by revisiting the divergent trajectories of the uprisings in Bahrain, Oman, Saudi Arabia and Kuwait.
