A forensic examination of four popular cross‐platform file‐sharing apps with Wi‐Fi P2P

File‐sharing apps with Wi‐Fi hotspot or Wi‐Fi Direct functions become more popular. They can work on multiple platforms and allow users to transfer files in a concealed manner. However, when criminals use these apps in illegal activities, it becomes an important issue for investigators to find digital evidence on multiple platforms. At present, there are few studies on this topic, and most of them are limited to the single platform problem. In this paper, we propose a forensic examination method for four popular cross‐platform file‐sharing apps with Wi‐Fi hotspot and Wi‐Fi Direct functions: Zapya, SHAREit, Xender, and Feem. We use 22 static and live forensic tools for 11 platforms to acquire, analyze, and classify the forensic artifacts. In our experiments, we find many useful forensic artifacts and classify them into six categories. The experimental results can support law enforcement investigations of digital evidence and provide information for future studies on other cross‐platform file‐sharing apps.     

Validation of the 4‐aminophenol color test for the differentiation of marijuana‐type and hemp‐type cannabis

The analysis of cannabis plant material submitted to seized‐drug laboratories was significantly affected by the signing of the Agricultural Improvement Act of 2018, which defined hemp and removed it from the definition of marijuana in the Controlled Substances Act. As a result, field law enforcement personnel and forensic laboratories now are in need of implementing new protocols that can distinguish between marijuana‐type and hemp‐type cannabis. Colorimetric tests provide a cost‐effective and efficient manner to presumptively identify materials prior to submission to a laboratory for analysis. This work presents the validation of the 4‐aminophenol (4‐AP) color test and demonstrates its utility for discriminating between marijuana‐type and hemp‐type cannabis (i.e., typification). Validation studies included the testing of numerous cannabinoid reference materials, household herbs, previously characterized cannabis plant samples, and real‐case samples. The 4‐AP test reliably produces a pink result when the level of Δ⁹‐tetrahydrocannabinol (THC) is approximately three times lower than the level of cannabidiol (CBD). A blue result is generated when the level of THC is approximately three times higher than that of CBD. Inconclusive results are observed when the levels of THC and CBD are within a factor of three from each other, demonstrating the limitations of the test under those scenarios.     

Staying Out: Reentry Protective Factors Among Rural Women Offenders

The current study examines protective factors for women who transition from county jails to rural Appalachian communities, areas with limited health and behavioral health services. The study included drug-using women recruited from three jails in rural Appalachia and followed-up at 12-months post-release. Analyses focused on differences between women who remained in the community and those who returned to custody, as well as a multivariate model to determine protective factors for reentry success. At the bivariate level, staying out of jail was associated with being older, having a job, not using drugs, stable housing, receiving health treatment, and having prosocial peers. In the multivariate model, the most robust predictors of staying out of jail were drug use abstinence, health care utilization, and prosocial peers. Most research on criminogenic needs associated with reentry success have focused on men, and most focused on reentry to urban communities where services and resources are more accessible. These findings have important implications for criminal justice systems to implement reentry programs for women offenders during the transition to the community.     

The Logic of Terrorism: Existential Anxiety,the Search for Meaning,and Terrorist Ideologies

Drawing from the work of political theorists, theologians, anthropologists, journalists, philosophers, and contemporary psychologists studying Terror Management Theory (TMT), it becomes possible to see that the concepts of existentialism and ideology may be useful for modern thinkers attempting to understand a problem such as terrorism. Integrating work from these fields makes it possible to see that terrorism may be driven by an existential-terroristic feedback loop: a cycle in which people support or engage in terrorism to alleviate existential anxiety but ultimately find this anxiety exacerbated in the wake of the violence they create or sanction. The loop is closed when this exacerbated anxiety compels them to reaffirm their support of, or participation in, terrorist violence. If this model is valid, then effectively addressing the problem of terrorism requires joining existing U.S. policies with policies that address ideologies. Specifically, policies must aspire to a) mitigate existential anxiety, b) provide a compelling counter-narrative, c) address environmental factors conducive to radicalization, d) prevent the formation of radicalized groups, and e) deradicalize existing ideologues.

Just compensation: a no-fault proposal for research-related injuries

Biomedical research, no matter how well designed and ethically conducted, carries uncertainties and exposes participants to risk of injury. Research injuries can range from the relatively minor to those that result in hospitalization, permanent disability, or even death. Participants might also suffer a range of economic harms related to their injuries. Unlike the vast majority of developed countries, which have implemented no-fault compensation systems, the United States continues to rely on the tort system to compensate injured research participants—an approach that is no longer morally defensible. Despite decades of US advisory panels advocating for no-fault compensation, little progress has been made. Accordingly, this article proposes a novel and necessary no-fault compensation system, grounded in the ethical notion of compensatory justice. This first-of-its-kind concrete proposal aims to treat like cases alike, offer fair compensation, and disburse compensation with maximum efficiency and minimum administrative cost. It also harmonizes national and international approaches—an increasingly important goal as research becomes more globalized, multi-site trials grow in number, and institutions and sponsors in the United States move to single-IRB review.     

Clinical psychologists’ perceptions of barriers and facilitators to engaging service users in index offence assessment and formulation within a medium secure unit

Index offence assessment and formulation (IOAF) helps service users (SU) in secure units to make sense of their index offence, provides detailed understanding of risk and contributes to treatment planning and discharge decisions. Clinical psychologists’ perceptions of barriers and facilitators to engaging SUs in IOAF within the men’s and women’s services of one medium secure unit were explored through focus groups. Thematic analysis identified two relevant domains: person-specific factors and the organisational context. Person-specific barriers included challenges in working with fragmented narratives, conflicting motivations to engage, SU defences and distorted perceptions of clinical psychologists’ roles. Giving clarity and choice to SUs facilitated engagement with the work. Regarding the organisational context, clinical psychologists within both services identified the importance of having adequate resources and care-team support to complete this work. Findings highlight the importance of developing an evidence-based framework for IOAF to be embedded within clear ‘risk’ care pathways through secure services.
