Accuracy Rates of Sex Estimation by Forensic Anthropologists through Comparison with DNA Typing Results in Forensic Casework

A common task in forensic anthropology involves the estimation of the biological sex of a decedent by exploiting the sexual dimorphism between males and females. Estimation methods are often based on analysis of skeletal collections of known sex and most include a research‐based accuracy rate. However, the accuracy rates of sex estimation methods in actual forensic casework have rarely been studied. This article uses sex determinations based on DNA results from 360 forensic cases to develop accuracy rates for sex estimations conducted by forensic anthropologists. The overall rate of correct sex estimation from these cases is 94.7% with increasing accuracy rates as more skeletal material is available for analysis and as the education level and certification of the examiner increases. Nine of 19 incorrect assessments resulted from cases in which one skeletal element was available, suggesting that the use of an “undetermined” result may be more appropriate for these cases.     

Radicalisation theories,policing practices,and “the future of terrorism?”

This article explores how theories of radicalisation have placed an emphasis on the development of an indicators-based approach to identify individuals who might engage in politically motivated violence. We trace how policing agencies have juxtaposed the search for indicators as a defence against criticisms of racial profiling. However, through an analysis of Canadian counter-terrorism training programmes, we demonstrate that the search for radicalisation indicators reaffirms pre-emptive and discriminatory security practices. We insist that despite efforts to theorise radicalisation outside of the practices of the “war on terror”, current trends risk rationalising prejudicial policing that affirms social exclusion and injustice.     

Ethnic Conflict and the New Legalism in China

In October 2014, the Chinese Communist Party committed to the establishment of a “socialist rule of law with Chinese characteristics.” Since then a group of Chinese political elites that we refer to as new legalists has been calling for ethnic conflict to be managed in accordance with the rule of law. This article finds that the deeply embedded and highly politicized problem of ethnic conflict in China lends credence to the legalist position that new law-based approaches are needed, although a number of practical problems arise when attempting to strengthen the rule of law. There are for instance powerful factions in the country supporting the continuation of repressive policies or selective ethnic preferentialism, and there are relatively low levels of legal awareness in ethnic-minority communities and general inadequacies in the Chinese legal system. We argue that an elite group of new legalists in China is attempting to reshape ethnic-minority policy in order to break free from the everyday protean politics of ethnic relations that is based largely on a negative cycle of violent confrontation and financial compensation.     

Labeling effects of initial juvenile justice system processing decision on youth interpersonal ties*

The juvenile justice system can process youth in myriad ways. Youth who are formally processed, relative to being informally processed, may experience more public and harsh sanctions that label youth more negatively as “deviant.” Drawing on labeling theory, the current study evaluates the relative effect of formal justice system processing on the interpersonal dynamics of youth peer networks. Using data from the Crossroads Study, a multisite longitudinal sample of first-time adolescent offenders, the current study applies augmented inverse probability weighting and generalized mixed-effects models to estimate the effects of formal processing on friendship selection processes of homophily and withdrawal and considers whether these effects vary by race and ethnicity. Consistent with expectations of homophily, formally processed youth acquire more new deviant peers and fewer nondeviant peers during the 3 years after their initial processing decision compared with informally processed youth. The findings suggest no differences exist across processing types in withdrawal from friends. These effects were consistent across racial and ethnic groups. Ultimately, this study explores the dynamic interpersonal mechanisms associated with labeling theory and offers additional insight into the negative effects of formal processing.     

Effects of obesity on talar micro- and macro-morphology

The addition of information regarding obesity status to the forensic anthropological biological profile could significantly contribute to the identification of human skeletal remains since over 40% of the U.S. adult population is currently obese. This study examines the differences in talar shape and trabecular bone structure between obese and non-obese individuals. A sample of 20 obese and 20 non-obese divided evenly by sex was selected from the Texas State University Donated Skeletal Collection. Tali were imaged using x-ray computed tomography (voxel size: 28–38.7 μm). Image stacks were processed to produce binary images as well as trabecular thickness and spacing maps. Landmark-based geometric morphometric analyses were conducted to quantify shape variation. Shape coordinates were used to locate 100 geometrically homologous volumes of interest within each talus. Bone volume fraction, trabecular thickness, and trabecular spacing were extracted at each volume of interest. Within each sex, a one-way ANCOVA was used to determine if significant differences exist between obese and non-obese individuals in trabecular bone after controlling for age. The size of the talus as well as subtle aspects of shape were found to distinguish the sexes. The results further indicate that bone volume fraction significantly differs between obese and non-obese males. In females, bone volume fraction is correlated with age but does not differ between obese and non-obese. The study demonstrates that bone microstructure is a promising approach to estimating body mass or body mass index category but age effects diminish the potential for the talus to be used alone.     

Decoding hidden darknet networks: What we learned about the illicit fentanyl trade on AlphaBay

The opioid epidemic, impacted from the proliferation of fentanyl, has added impetus to the need to detect fentanyl, sources of fentanyl, and places where fentanyl and drugs adulterated with fentanyl are available. Many darknet marketplaces (DNMs) have rules that ban fentanyl. However, it is unclear how these affect the fentanyl market. Using the AlphaBay DNM as a case study, we conducted mixed methods qualitative research. We scraped and analyzed data from the AlphaBay I2P website using, among other methods, content and social network analysis, to uncover hidden fentanyl networks. Our research highlights the next evolution of darknet marketplaces – the migration of DNMs from Tor to I2P and the methods that can be used identify fentanyl networks, irrespective of where sites are: I2P, Tor, or multihomed on I2P and Tor. Despite its ban in the Global AlphaBay Rules, our research revealed the sale of fentanyl on the AlphaBay DNM. Unlike previous studies, our findings predominantly revealed the covert sale of fentanyl on AlphaBay and predatory vendors selling illicit drugs, which unbeknownst to buyers, contained fentanyl. To a lesser extent, our findings identified the overt sale of fentanyl patches on AlphaBay. Although we examined only one DNM, the prevalence of the covert sale of fentanyl and the presence of predatory vendors underscores the importance of research that decodes the language of vendors who surreptitiously sell fentanyl or drugs adulterated with fentanyl or other illicit substances. The results of our research can inform strategies aimed at disrupting and dismantling DNM fentanyl networks.     

LGBTQ Youth in the Child Welfare System: An Overview of Research,Practice, and Policy

LGBTQ youth are largely overrepresented in the child welfare system. The experiences of LGBTQ youth have largely been overlooked. LGBTQ youth often encounter a number of challenges and disparities as they navigate the child welfare system. Many report experiences of discrimination, marginalization, and an overall lack of acceptance. The permanency and placement options have historically been limited for many LGBTQ youth, often leading to an over reliance on congregate settings and aging out of foster are. The current article provides a synthesis of the existing research on the experiences and outcomes of LGBTQ youth in care, as well as an exploration of the policy and practice initiatives aimed at creating a more inclusive system of care.     

Professionals' Contribution to the Legislative Process: Between Self,Client, and the Public

How may professionals be made to contribute to legislative processes so that their expertise redounds to the public interest, despite the legislative product being likely to have a negative impact on their clients' wealth? Drawing on a case study of the legislative process that gave birth to Israel's recent (2002–2008) trusts taxation regime, based on five years of participant observation among the trust professional community, I find that to obtain the benefit of private‐sector professionals' expertise under such circumstances, government should have legislation drafted in a dispassionate, exclusive environment of experts rather than in the political arena; it should build professionals' trust in government by adopting an explicitly collegial approach; it should focus reform efforts on elements of the existing law so clearly inequitable as to make a refusal to contribute difficult to justify; and take care that the new regime creates a compliance practice lucrative enough to compensate for any loss to professionals consequent on its enactment. Once professionals' interests are suitably safeguarded, their loyalty to clients appears surprisingly brittle and government can successfully combine with them in the public interest.     

Promoting Daily Well-being in Adolescents using mHealth

Adolescents are at increased risk for developing mental health problems. The Grow It! app is an mHealth intervention aimed at preventing mental health problems through improving coping by cognitive behavioral therapy (CBT)-inspired challenges as well as self-monitoring of emotions through Experience Sampling Methods (ESM). Yet, little is known about daily changes in well-being and coping during a stressful period, like the COVID-19 pandemic. The current study aimed to elucidate daily changes in positive and negative affect, and adaptive coping, and to better understand the within-person’s mechanisms of the Grow It! app. The sample consisted of 12–25-year old Dutch adolescents in two independent cohorts (cohort 1: N?=?476, Mage?=?16.24, 76.1% female, 88.7% Dutch; cohort 2: N?=?814, Mage?=?18.45, 82.8% female, 97.2% Dutch). ESM were used to measure daily positive and negative affect and coping (cohort 1: 42 days, 210 assessments per person; cohort 2: 21 days, 105 assessments). The results showed that, on average, adolescents decreased in daily positive affect and adaptive coping, and increased in their experienced negative affect. A positive relation between adaptive coping and positive affect was found, although independent of the CBT-based challenges. Latent class analysis identified two heterogeneous trajectories for both positive and negative affect, indicating that the majority of participants with low to moderate-risk on developing mental health problems were likely to benefit from the Grow It! app.
