The Nurture Versus Biosocial Debate in Criminology: On the Origins of Criminal Behavior and Criminality takes a contemporary approach to address the sociological and the biological positions of human behavior by allowing preeminent scholars in criminology to speak to the effects of each on a range of topics. Kevin M. Beaver, J.C. Barnes, and Brian B. Boutwell aim to facilitate an open and honest debate between the more traditional criminologists who focus primarily on environmental factors and contemporary biosocial criminologists who examine the interplay between biology/genetics and environm

Moffitt's (1993) developmental theory has garnered an extensive amount of attention from scholars across a range of disciplines, and the results generated from this body of literature have been consistently supportive. Specifically, the segment of the population predicted by Moffitt to be chronically aggressive—called life-course persistent offenders—has been found to account for a disproportionate number of serious crimes. What remains less certain, however, is whether this same group of offenders are also responsible for perpetrating acts of forced sex. The authors examined the tendency for life-course persisters to sexually assault using a nationally representative sample of individuals. Our findings suggest that life-course persisters are disproportionately more likely to be sexually coercive compared to other individuals.

Given that enlistment in the U.S. military is completely voluntary, there has been a great deal of interest in identifying the various factors that might explain why some people join the military, whereas others do not. The current study expanded on this line of literature by estimating the extent to which genetic and environmental factors explained variance in the liability for lifetime participation in the military. Analysis of twin pairs drawn from the National Longitudinal Study of Adolescent to Adult Health (Add Health) revealed that 82% of the variance was the result of genetic factors, 18% of the variance was the result of nonshared environmental factors, and none of the variance was accounted for by shared environmental factors. In light of a number of limitations, replication studies are needed to determine the robustness of these findings and whether they are generalizable to other samples and populations.

Nearly 13 million children in the United States live in households struggling with food insecurity. Although biosocial theories suggest a strong link between the lack of food and child maltreatment, and a handful of studies have established a correlation between nutritional deficits and family violence, it is unclear if household food insecurity itself is associated with physical and psychological child abuse apart from other issues related to poverty. The current study examines this possibility by analyzing data from the Fragile Families and Child Wellbeing Study ( n = 2,330). Sixteen percent of households were food insecure, and food insecurity at Wave 3 was associated with an increased use of parent-to-child psychological and physical aggression at the follow-up interview. This relationship held even after controlling for important covariates, such as maternal depression and impulsivity. We conclude by discussing what additional research is required, as well as how our findings might intersect with social policy on this topic.

Background:Despite an emphasis on a biopsychosocial understanding of human behavior and the relevance of biosocial research to social work practice, it is unclear whether social work is contributing to biosocial research and knowledge.Methods:Systematic review procedures were employed to locate studies that included biological variables (e.g., genetic or physiological factors) related to behavior and were published in a social work journal between 2000 and 2015. Seventy-five social work journals were searched. Studies were screened and coded by two independent reviewers.Results:Eleven studies were eligible for this review; one was a behavior genetics study, two were molecular genetics studies, two were neurological studies, and six studies examined physiological factors such as skin conductance and salivary cortisol.Discussion:Findings suggest that social work as a discipline is not contributing new knowledge to advance the "bio" component of the biopsychosocial framework. Implications and recommendations are discussed.

Converging lines of research suggest that self‐control and language may be inextricably linked. No empirical research has ever examined this proposition, however. We address this gap in the literature by analyzing a sample of twin pairs from a nationally representative data set of children. The results revealed three broad findings. First, diminished language skills were predictive of low self‐control both cross‐sectionally and longitudinally. Second, the covariation between language and self‐control was linked to both genetic and environmental factors. Third, after controlling for genetic influences on self‐control, language skills were predictive of variation in individual levels of self‐control. The theoretical implications of these findings are discussed.

In a recent article published in Criminology, Burt and Simons () claimed that the statistical violations of the classical twin design render heritability studies useless. Claiming quantitative genetics is "fatally flawed" and describing the results generated from these models as "preposterous," Burt and Simons took the unprecedented step to call for abandoning heritability studies and their constituent findings. We show that their call for an "end to heritability studies" was premature, misleading, and entirely without merit. Specifically, we trace the history of behavioral genetics and show that 1) the Burt and Simons critique dates back 40 years and has been subject to a broad array of empirical investigations, 2) the violation of assumptions in twin models does not invalidate their results, and 3) Burt and Simons created a distorted and highly misleading portrait of behavioral genetics and those who use quantitative genetic approaches.
