Personal identification of cold case remains through combined contribution from anthropological, mtDNA, and bomb-pulse dating analyses

In 1968, a child's cranium was recovered from the banks of a northern Canadian river and held in a trust until the "cold case" was reopened in 2005. The cranium underwent reanalysis at the Centre for Forensic Research, Simon Fraser University, using recently developed anthropological analysis, "bomb-pulse" radiocarbon analysis, and forensic DNA techniques. Craniometrics, skeletal ossification, and dental formation indicated an age-at-death of 4.4 ± 1 year. Radiocarbon analysis of enamel from two teeth indicated a year of birth between 1958 and 1962. Forensic DNA analysis indicated the child was a male, and the obtained mitochondrial profile matched a living maternal relative to the presumed missing child. These multidisciplinary analyses resulted in a legal identification 41 years after the discovery of the remains, highlighting the enormous potential of combining radiocarbon analysis with anthropological and mtDNA analyses in producing confident personal identifications for forensic cold cases dating to within the last 60 years.     

Characteristics of sexual assault and disclosure among women in substance abuse recovery homes

Research suggests that many women experience some form of sexual assault in their lifetime and that women who engage in substance abuse often have a higher incidence of past sexual assault than women in the general population. Given the documented rates of sexual assault among women in recovery from substance use, it is important to explore community interventions that promote positive recovery from substance use and sexual assault. One model that promotes successful substance use recovery is the Oxford House--a democratic, self-supported substance use recovery home. Research demonstrated that living in an Oxford House provides sober social support and that this increased social support may promote the use of positive coping strategies to strengthen recovery from substance use, however; the relationship between social support and sexual assault for women is unclear. Thus, the current study examines the Oxford House model for women in recovery from substance use who have experienced sexual assault. A cross-sectional sample of women living in Oxford Houses in the United States was obtained to examine the relationship among disclosure of sexual assault, social support, and self-esteem. Results suggested that many women used Oxford House as a setting in which to disclosure prior sexual assault. Results also indicated that women who disclosed their assault experience reported higher self-esteem and social support than women who had not disclosed. Possible implications include the value of substance abuse recovery homes as a safe, supportive environment for women to address issues related to sexual assault.     

Impact of Intimate Partner Violence on Women’s Mental Health

This study aimed to explore the mental health needs of women residing in domestic violence shelters; more specifically, we aimed to identify commonalities and differences among their mental health needs. For this purpose, qualitative and quantitative data was collected from 35 women from a Midwestern domestic violence shelter. Hierarchical clustering was applied to quantitative data, and the analysis indicated a three-cluster solution. Data from the qualitative analysis also supported the differentiation of women into three distinct groups, which were interpreted as: (A) ready to change, (B) focused on negative symptoms, and (C) focused on feelings of guilt and self-blame.     

Relational demography and officer occupational attitudes: The influence of workgroup context

Purpose

Researchers have long held an interest in understanding what role officer demographics play in explaining occupational attitudes. Despite this interest, evidence has consistently shown such relationships to be inconsistent. Using a relational demography framework that is based on the notion that demographic effects are contextual rather than universal across all officers, the current study examines the extent to which officer demographics influences their occupational attitudes when viewed in relation to other officers in their assigned workgroup.

Methods

Surveys of 1,022 patrol officers assigned to 187 workgroups were used to examine demographic effects across a number of occupational attitudes. A series of multilevel modeling techniques were used to test the viability of the relational demography framework.

Results

Certain demographic effects changed or were attenuated after accounting for workgroup membership. Demographic effects were also found to differ across workgroup contexts. Finally, results for job satisfaction indicated that gender and experience effects were dependent upon the demographic and cultural context of the workgroup.

Conclusions

Demographic-attitudinal relationships are influenced by the broader workgroup environment. The results also highlight the importance of taking into consideration non-independence issues associated with attitudes and demographics from both theoretical and analytical perspectives.     

On the Nature of Harms Reported by those Identifying a Problematic Drinker in the Family,an Exploratory Study

A national telephone survey on alcohol-related harms experienced by others consisted of 2,649 randomly selected adults and 415 (15 %) commented on the family member whose heavy drinking most negatively affected them. Relationships comprised close family (child, parent, sibling; 47 %), partner (22 %), extended family (e.g., aunt/uncle, cousin, grandparent; 19 %), and ex-partner (12 %). Common harms were being emotionally hurt and having a serious argument. An average of 3.4 harms was reported and multiple harms meant a higher likelihood of significant impact. Harms were classified into four domains which accounted for approximately 60 % of the explained variance: psychological (26.1 %), physical (11.4 %), social (10.9 %), and practical (9.6 %). Psychological and practical domains were associated with significant harm as were being female and sharing a home with the drinker. Perceived harms from a problematic drinking family member are broad ranging and have significant impact. Advice, information, and directions for family members dealing with a problematic drinker need development.     

Explanations of a Violent Relationship: The Male Perpetrator’s Perspective

The purpose of this study was to understand the way male perpetrators’ perceive and explain intimate partner violence (IPV) in their relationship. Specifically, men were invited to reflect upon their role in their relationship when violence exists, their contributions to the violence, and how they felt about it. Using coding procedures from grounded theory methodology, researchers analyzed data from 13 men who had been in violent relationships. Seven key themes were identified from 104 significant statements. These themes included justification, relapse, control, anger, emotional threshold, triggers, and remorse. Clinical implications as well as suggestions for future research are presented.     

The New Ecology of Tornado Warning Information: A Natural Experiment Assessing Threat Intensity and Citizen‐to‐Citizen Information Sharing

The complexity of the modern information ecosystem raises many questions for public organizations. In the context of emergency management, information (such as warning messages) is communicated not only from a source of authority to the public but also between members of the public. The authors use a series of storms that affected Oklahoma in the spring of 2016 to test propositions related to how information about tornado warnings reached the public and who received and shared information about the storm, as well as to identify how gender and age mediate the influence that exposure to an extreme weather event has on the sharing of this information. Overall, the authors find that reported exposure to a tornado increases information sharing through a variety of media and technology. The effect of the tornado erases the otherwise present gender gap in sharing information, while it has little effect on the media platforms that are most popular among older respondents.
