Do homicide rates increase during weekends and national holidays?

In the UK there has been limited research examining temporal patterns of homicide. To our knowledge, no studies have linked patterns of homicide to the mental health characteristics of the perpetrator. The study examined a national consecutive case series of homicide offences committed between January 1996 and December 2015 in England. Clinical data were collected by the National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH). During this period 10,563 people committed a homicide. The offences were more likely to occur at the weekend, mostly on a Saturday. Weekend homicides were associated with: perpetrators under the age of 25, males and alcohol consumption. Homicides increased markedly on New Year’s Day, and public holidays. Those with a history of mental illness more commonly committed homicide during weekdays, suggesting a different pattern of offending. No change in pattern was found after licensing hours were extended in 2005 to allow 24-h licencing for the sale of alcohol. A public health approach should focus on educating young people on the health risks associated with alcohol, promoting responsible drinking and conflict avoidance, specifically on special events and at weekends.     

A simulation for exploring the effects of the "trait list" method's subjectivity on consistency and accuracy of ancestry estimations

The nonmetric "trait list" methodology is widely used for estimating ancestry of skeletal remains. However, the effects of the method's embedded subjectivity on subsequent accuracy and consistency are largely unknown. We develop a mathematical simulation to test whether variation in the application of the "trait list" method alters the ancestry estimation for a given case. Our simulation explores how variations in (i) trait selection, (ii) number of traits employed, and (iii) ancestry choice thresholds affect the ancestry estimation of an unidentified skeleton. Using two temporally and geographically diverse samples, the simulation demonstrates that trait selection, trait quantity, threshold choices, and the exclusion of high-frequency traits had minimal effect on estimation of general ancestry. For all data sets and Runs, Accuracy(AS) was maintained above 90%. The authors close with a discussion on the logistical issues present when choosing traits, and how to avoid ancestry bias.     

Enduring neoliberalism in Alberta's oil sands: the troubling effects of private–public partnerships for First Nation and Métis communities

Changes in federal government relations with First Nations and Métis in Canada have been described as shifting over time, from fur trade colonialism, to welfare colonialism, to neoliberal partnerships. Acknowledging changes and continuities in Aboriginal peoples–state relations over time, this article examines the effects of recent policies that emphasize private–public partnerships for economic development on Indigenous communities in northern Alberta. We argue that while the term ‘partnership’ connotes equality, cooperation, and consensus, the actual workings of partnerships are anything but equal, and the effects include fragmentation, competition, and lack of overall accountability. These outcomes work against the needs and aspirations of Indigenous communities.     

Parenting without Protection: How Legal Status Ambiguity Affects Lesbian and Gay Parenthood

Through the lens of lesbian and gay parenthood we ask how individuals who experience “legal status ambiguity”—that which emerges when legal fluctuations combine with divided attitudes, ignorance of the law, and autonomous institutional gatekeepers—exercise their legal rights and responsibilities. The results from thirty‐one interviews with lesbian and gay parents in Oregon and their six adult children suggest that the state's fluctuating legal and social climates for lesbian and gay parenting between 1985 and 2013 presented significant challenges for two generations of same‐sex parents. Although both cohorts created and utilized a range of legal and social mechanisms to assert their legal rights, they found these rights to be controlled as much by gatekeeper perspectives as by legal force. After the 2015 Obergefell ruling on marriage equality, lesbian and gay parenting status remains a site of ongoing legal and social contestation, providing insight into the risks and challenges of legal status ambiguity.     

An exploratory study in methods of distinguishing destructive cults

Abstract

Drawing extensively on academic and anti cult literature and paying particular attention to theories of how cults become destructive, this small-scale exploratory study deconstructed 25 cults into a number of constituent behaviours, practices and beliefs. A preliminary multivariate analysis revealed that 7 behaviours might form the basis of discriminating destructive from more benign cults. These 7 behaviours, which were most closely correlated with overt destructive acts (mass suicide and mass murder) did distinguish the five demonstrably destructive religious cults (Aum Shinri Kyo. Order of the Solar Temple, Brunch Davidians, Heaven's Gate, Jim Jones Jonestown) associated with major loss of life from the remaining 20 cults examined. The exception to this was The House of Yahweh, which was not theoretically classified as destructive but was empirically classified as such in this analysis. The study demonstrated clear patterns of behaviour and beliefs that are at variance with those identified by other authors who have adopted a more conceptual approach.     

The development of a filter model for prioritising suspects in burglary offences

Abstract

This paper discusses the development of a filter model for prioritizing possible links in dwelling burglary. The filters utilize the central aspects of crime scene information that is available and accessible to investigators in burglary, namely geo-spatial, temporal, behavioural, and dwelling information. The proposed filters were analysed using a sample of 215 dwelling burglaries committed by 43 serial burglars (i.e. 5 offences each) in order to determine the sequence in which the filters should be considered in prioritizing possible linked offences. The results indicated that the following order (i.e. better performance to worse performance) was most effective at linking offences, utilizing: (1) geo-spatial information, (2) temporal aspects, (3) behavioural information and, lastly, (4) dwelling characteristics. Specifically, the results indicated that offences in close proximity to one another should be given priority. Further, any offence occurring within a 28-day span before or after the index offence should be given priority. The paper argues that behavioural and dwelling characteristics are less effective for linking than geo-spatial and temporal information because the former two aspects are influenced significantly by situational and contextual cues on offender decision-making.
