Journey history reconstruction from the soils and sediments on footwear: An empirical approach

The value of environmental evidence for reconstructing journey histories has significant potential given the high transferability of sediments and the interaction of footwear with the ground. The importance of empirical evidence bases to underpin the collection, analysis, interpretation and presentation of forensic trace materials is increasingly acknowledged. This paper presents two experimental studies designed to address the transfer and persistence of sediments on the soles of footwear in forensically relevant scenarios, by means of quartz grain surface texture analysis, a technique which has been demonstrated to be able to distinguish between samples of mixed provenance.It was identified that there is a consistent trend of transfer and persistence of sediments from hypothetical pre-, syn- and post-crime event locations across the sole of the shoe, with sediments from ‘older’ locations likely to be retained in small proportions. Furthermore, the arch of the shoe (the area of lowest foot pressure distribution) typically (but not exclusively) retained the highest proportion of grain types from previous locations including the crime scene. A lack of chronological layering of the retained sediments was observed indicating that techniques that can identify the components of mixed provenance samples are important for analysing footwear sediment samples. It was also identified that the type of footwear appeared to have an influence on what particles were retained, with high relief soles that incorporate recessed areas being more likely to retain sediments transferred from ‘older’ locations from the journey history. In addition, the inners of footwear were found to retain sediments from multiple locations from the journey history that are less susceptible to differential loss in comparison to the outer sole. These findings provide important data that can form the basis for the effective collection, analysis and interpretation of sediments recovered from both the outer soles and inners of footwear, building on the findings of previously published studies. These data offer insights that enable inferences to be made about mixed source sediments that are identified on footwear in casework, and provide the beginnings of an empirical basis for assessing the significance of such sediment particles for a specific forensic reconstruction.     

A case study in public child welfare: county-level practices that address racial disparity in foster care placement

Racial disproportionality has been a longstanding issue within child welfare. The continued overrepresentation of black children in the foster care system is troubling. The authors of this article conducted a case study of two counties in New York State that have steadily decreased the number of black children in foster care in an effort to identify what aspects of their child welfare practice impacted the decline. The case study employed document analysis, in-depth interviews, and focus groups with child removal decision makers. Utilizing a grounded theory approach to content organization and analysis, several themes emerged as noticeable factors. Some of the most salient themes included preventive services and resources, community collaborations, case practice development, family meetings, workforce diversity, the court system, and, the most unique, blind removal meetings. The themes found in this study present promising practices to assist in decreasing the racial disparity in child welfare removal decisions.     

Settlement of refugee women and children following the Second World War: challenges to the family

Abstract

Following the Second World War, refugees that were displaced as a result of conflict became a global concern. Many of these displaced persons were resettled under the auspices of the International Refugee Organization. Large numbers of European displaced persons settled in Australia, with significant numbers living in Queensland. The wartime and migration experiences of refugees have the potential to influence settlement experiences, and for displaced persons who settled in Queensland, these prior experiences continued to resonate within the family throughout the settlement process. Many refugee children became separated from their families, and while some were reunited, the process was lengthy and not without its difficulties. The effect of separation and loss experienced by these families dominated the post-war experience. It presented challenges to mothers, children and families as they negotiated the uncertainty of displacement and the potential for resettlement, and affected their approaches to separation and reunification. The separation and reunification of children and families played a significant role in the settlement process, influencing interactions with Australian organisations and the development of familial and social network connections during settlement. The legacy of conflict and separation continued to resonate within families and influenced perspectives of the ongoing settlement process for child refugees.     

User review portability: Why and how?

User reviews of products on the e-commerce platforms are a critical determinant of inter-platform competition, as a large number of consumers base their purchasing choices on the related reviews written by other users. The network effects between the number of reviews and new users give a sustainable competitive advantage to incumbent platforms. While business literature has recognised the commercial value of the user reviews, legal scholarship has paid little attention to levelling the playing field between incumbents and new e-commerce platforms by exploring the portability of user reviews. This paper bridges this gap. We explore the possibility of porting user reviews through two legal mechanisms—first, traditional Intellectual Property law; second, the new Right to Data Portability (RtDP) as enshrined in the GDPR. After recognising the limitations of these mechanisms in enabling the portability of reviews, we suggest that pure data aggregators, such as Personal Information Management Services (PIMS), are best placed to make user reviews available to multiple platforms.     

“Legality with a Vengeance”: Reclaiming Distribution for Sociolegal Studies

The law and society community has argued for decades for an expansive understanding of what counts as “law.” But a content analysis of articles published in the Law & Society Review from its 1966 founding to the present finds that since the 1970s, the law and society community has focused its attention on laws in which the state regulates behavior, and largely ignored laws in which the state distributes resources, goods, and services. Why did socio‐legal scholars avoid studying how laws determine access to such things as health, wealth, housing, education, and food? We find that socio‐legal scholarship has always used “law on the books” as a starting point for analyses (often to identify departures in “law in action”) without ever offering a programmatic vision for how law might ameliorate economic inequality. As a result, when social welfare laws on the books began disappearing, socio‐legal scholarship drifted away from studying law's role in creating, sustaining, and reinforcing economic inequality. We argue that socio‐legal scholarship offers a wide range of analytical tools that could make important contributions to our understanding of social welfare provision.     

Trauma-Informed Resource Parent Training and the Impact on Knowledge Acquisition,Parenting Self-Efficacy,and Child Behavior Outcomes: A Pilot of the Resource Parent Curriculum Parent Management Training (RPC+)

This pilot study illustrates one state’s development, implementation, and outcomes of a trauma-informed curriculum called the Resource Parent Curriculum + CARE (RPC+). The RPC+ is an intensive co-trained curriculum intended to be trauma-informed and skills-based focused on ameliorating child behavior problems that are frequently the source of parenting stress and placement instability. This article will provide a literature review of child and caregiver needs, describe the training curriculum, and present the results from the pilot implementation of the curriculum. Preliminary findings from this study show participants of the RPC+ show positive changes pre- to post-training on a number of dimensions that have been correlated with placement stability for children including knowledge of trauma, parenting self-efficacy, and child behavior outcomes.     

Report of Increasing Overdose Deaths that include Acetyl Fentanyl in Multiple Counties of the Southwestern Region of the Commonwealth of Pennsylvania in 2015–2016

Acetyl fentanyl is a Schedule I controlled synthetic opioid that is becoming an increasingly detected “designer drug.” Routine drug screening procedures in local forensic toxicology laboratories identified a total of 41 overdose deaths associated with acetyl fentanyl within multiple counties of the southwestern region of the state of Pennsylvania. The range, median, mean, and standard deviation of blood acetyl fentanyl concentrations for these 41 cases were 0.13–2100 ng/mL, 11 ng/mL, 169.3 ng/mL, and 405.3 ng/mL, respectively. Thirty‐six individuals (88%) had a confirmed history of substance abuse, and all but one case (96%) were ruled multiple drug toxicities. This report characterizes this localized trend of overdose deaths associated with acetyl fentanyl and provides further evidence supporting an alarmingly concentrated opiate and opioid epidemic of both traditional and novel drugs within this region of the United States.     

Canine Population Data Generated from a Multiplex STR Kit for Use in Forensic Casework*

Abstract: Canine biological specimens are often part of the physical evidence from crime scenes. Until now, there have been no validated canine‐specific forensic reagent kits available. A multiplex genotyping system, comprising 18 short tandem repeats (STRs) and a sex‐linked zinc finger locus for gender determination, was developed for generating population genetic data assessing the weight of canine forensic DNA profiles. Allele frequencies were estimated for 236 pedigreed and 431 mixed breed dogs residing in the U.S. Average random match probability is 1 in 2 × 10³³ using the regional database and 1 in 4 × 10³⁹ using the breed dataset. Each pedigreed population was genetically distinct and could be differentiated from the mixed breed dog population but genetic variation was not significantly correlated with geographic transition. Results herein support the use of the allele frequency data with the canine STR multiplex for conveying the significance of identity testing for forensic casework, parentage testing, and breed assignments.
