Is marijuana really a gateway drug? A nationally representative test of the marijuana gateway hypothesis using a propensity score matching design

Understanding the factors that affect the severity of juvenile stranger sex offenses: the effect of victim characteristics and number of suspects

Understanding factors that affect the severity of a juvenile-stranger sexual assault has implications for crime prevention, and potentially, the assessment and treatment of juvenile sex offenders. This study investigated how victim characteristics and the number of suspects affected the use of physical violence and weapons and the occurrence of penetration in 495 allegations of sexual assault committed by juveniles against strangers. Statistically significant interactions between victim age and gender were found for occurrence of penetration and use of violence. Differences in offense characteristics were also found between offenses with varying victim-suspect age differences. When comparing the rate of penetration in the presence and absence of violence, little change was observed for lone suspects. However, the rate of penetration increased significantly for groups in the presence of physical violence, suggesting that violence in this context may be more expressive than instrumental. Theoretical explanations and practical implications are considered.     

Persons with intellectual disabilities in the criminal justice system: review of issues

Although the vast majority of individuals with intellectual disabilities (ID) are law-abiding citizens, there is a small percentage with offending behaviour that is considered antisocial, socially inappropriate, or defined as illegal. It has long been recognised that individuals with ID or mental-health needs who break the law should be dealt with differently from the general population. There have been an increasing number of empirical studies in this area; however, these have been plagued by various definitional and methodological issues. Prevalence estimates of offenders with ID are complicated by diagnostic variations and inconsistencies in the criminal justice process. International studies have shown a large range, from 2% to 40%, depending on methodological approaches. The following review will highlight the salient issues including prevalence of offending, characteristics of offenders, vulnerabilities within the legal system, assessment, and a brief overview of intervention and treatment approaches.     

A content analysis of fingerprint literature for educational curricula

Forensic science is being required to justify and elucidate its scientific foundations. One way of doing this is through academic curricula. For many native forensic sciences, these curricula do not exist. A content analysis of nine major books in fingerprints was conducted to develop a structure for curricula in that field. The results of this study can be used to organize course content and serve as a model for other disciplines with published materials but no coherent or standard curricula.     

‘Good soldiers are made,not born’⊥: the dangers of medicalizing ability in the military use of genetics

Advances in genetic and genomic science are of particular interest to the United States military. Responding to Maxwell J. Mehlman''s and Tracy Yeheng Li''s article Ethical, Legal, Social, and Policy Issues in the Use of Genomic Technology by the U.S. Military, this Commentary explores the social consequences of medicalizing what it means to be a good soldier. It begins by reviewing the well-documented consequences of medicalization in the contexts of the eugenics movement and modern genetic and genomic science. It then applies that analysis to the military use of genetics and genomics, focusing on the ways in which genetic or genomic accounts of military ability could entrench existing gender and racial disparities.     

Genetic differentiation between and within Northern Native American language groups: an argument for the expansion of the Native American CODIS database

The National Research Council recommends that genetic differentiation among subgroups of ethnic samples be lower than 3% of the total genetic differentiation within the ethnic sample to be used for estimating reliable random match probabilities for forensic use. Native American samples in the United States’ Combined DNA Index System (CODIS) database represent four language families: Algonquian, Na-Dene, Eskimo-Aleut, and Salishan. However, a minimum of 27 Native American language families exists in the US, not including language isolates. Our goal was to ascertain whether genetic differences are correlated with language groupings and, if so, whether additional language families would provide a more accurate representation of current genetic diversity among tribal populations. The 21 short tandem repeat (STR) loci included in the Globalfiler® PCR Amplification Kit were used to characterize six indigenous language families, including three of the four represented in the CODIS database (i.e. Algonquian, Na-Dene, and Eskimo-Aleut), and two language isolates (Miwok and Seri) using major population genetic diversity metrics such as F statistics and Bayesian clustering analysis of genotype frequencies. Most of the genetic variation (97%) was found to be within language families instead of among them (3%). In contrast, when only the three of the four language families represented in both the CODIS database and the present study were considered, 4% of the genetic variation occurred among the language groups. Bayesian clustering resulted in a maximum posterior probability indicating three genetically distinct groups among the eight language families and isolates: (1) Eskimo, (2) Seri, and (3) all other language groups and isolates, thus confirming genetic subdivision among subgroups of the CODIS Native American database. This genetic structure indicates the need for an increased number of Native American populations based on language affiliation in the CODIS database as well as more robust sample sets for those language families.Supplemental data for this article is available online at https://doi.org/10.1080/20961790.2021.1963088 .     

Intergenerational Transmission of Violence,Threatened Egoism,and Reciprocity: A Test of Multiple Psychosocial Factors Affecting Intimate Partner Violence

A myriad of factors have been advanced to explain intimate violence. This study was undertaken to investigate the effects on intimate violence of three specific concepts: threatened egoism, violence in the family of origin, and reciprocity. Self-report questionnaires were administered to a randomly selected cluster sample of 423 participants, 147 males and 276 females. While no support was found for threatened egoism, both violence witnessed in the family of origin and reciprocity were found to significantly influence intimate violence. Analyses conducted separately for males and females indicated that these factors operate differently based on gender.
