The Accumulation of Disadvantage: Criminal Justice Contact, Credit, and Debt in the Transition to Adulthood.

Social exclusion of those with criminal justice experience increasingly includes a financial component, but the structure of disadvantage in credit and debt remains unclear. We develop a model of financial disadvantage in debt-holding during the transition to adulthood among justice-involved groups. We study cumulative criminal justice contact and debt holding by age thirty using the NLSY97. We follow life-course theory and understand this Millennial cohort as transitioning to adulthood during an era of historically high criminal justice contact, with many experiencing arrests, convictions, and incarceration. We develop a distinct measurement approach to cumulative criminal justice contact by age thirty that captures variation between young adults in the severity of justice encounters in the early life course. We conceptualize financial disadvantage as a lower likelihood of holding debt that facilitates property and attainment investments and a higher likelihood of holding higher-cost debts used for consumption or emergencies. We find that those with the most punitive criminal justice contact evidence the most disadvantageous form of debt holding, exacerbating social exclusion. We consider the implications of the accumulation of financial disadvantage for our understanding of criminal justice contact as a life-course process that will continue to shape the Millennial cohort's future trajectory.

Network Integration within a Prison-Based Therapeutic Community.

Prison-based therapeutic communities (TCs) are a widespread, effective way to help incarcerated individuals address substance abuse problems. The TC philosophy is grounded in an explicitly relational paradigm that entails building community and conditioning residents to increasingly take responsibility for leadership therein. Although TCs are based on cultivating a network that continuously integrates new residents, many common structural features can jeopardize TC goals and are hence discouraged (e.g., clustering, homophily). In light of this tension, analyzing the TC from a network perspective can offer new insights to its functioning, as well as to broader questions surrounding how networks integrate new members. In this study we examine a men's TC unit in a Pennsylvania prison over a 10-month span. Using data on residents' informal networks, we examine: (1) how well individuals integrate into the TC network across time, (2) what predicts how well residents integrate into the TC, and (3) how well the TC network structure adheres to theoretical ideals. Results suggest that individual integration is driven by a range of hypothesized factors and, with limited exceptions, the observed TC is able to foster a network structure and integrate residents consistent with TC principles. We discuss the implications of these results for evaluating TCs and for understanding the process of network integration.

The responsiveness of criminal networks to intentional attacks: Disrupting darknet drug trade.

Physical, technological, and social networks are often at risk of intentional attack. Despite the wide-spanning importance of network vulnerability, very little is known about how criminal networks respond to attacks or whether intentional attacks affect criminal activity in the long-run. To assess criminal network responsiveness, we designed an empirically-grounded agent-based simulation using population-level network data on 16,847 illicit drug exchanges between 7,295 users of an active darknet drug market and statistical methods for simulation analysis. We consider three attack strategies: targeted attacks that delete structurally integral vertices, weak link attacks that delete large numbers of weakly connected vertices, and signal attacks that saturate the network with noisy signals. Results reveal that, while targeted attacks are effective when conducted at a large-scale, weak link and signal attacks deter more potential drug transactions and buyers when only a small portion of the network is attacked. We also find that intentional attacks affect network behavior. When networks are attacked, actors grow more cautious about forging ties, connecting less frequently and only to trustworthy alters. Operating in tandem, these two processes undermine long-term network robustness and increase network vulnerability to future attacks.

School suspension and social selection: Labeling, network change, and adolescent, academic achievement.

The growing body of research detailing the pronounced effects of criminal stigma on inequality in the US underscores the importance of labeling theory. In spite of the renewed interest in labeling, little research has evaluated the theoretical mechanisms underlying the theory. Drawing on the labeling perspective, this article evaluates mechanisms underlying the relationship between school punishment and reductions in adolescent academic achievement. It uses recent innovations in longitudinal network analysis to examine the consequences of school punishment as a dynamic interplay of labeling, network selection, and group influence. Results indicate that school punishment facilitates selection into academically underperforming peer networks and that this change in network composition is largely responsible for the association between school punishment and reductions in adolescent academic achievement.

Evaluating peer-influence processes in a prison-based therapeutic community: a dynamic network approach.

BACKGROUND: The Therapeutic Community (TC) is a common treatment modality for incarcerated individuals with substance use disorders. TCs rely on peer group processes to promote lasting behavioral and identity change, yet prior research has not adequately tested the peer influence mechanisms underlying the theoretical model. This study applied dynamic network analysis to estimate peer influence processes central to TC philosophy. METHODS: A stochastic actor-oriented model (SAOM) was applied to ten months of social network data collected from prisoner surveys within a TC unit (N = 62) in a medium-security Pennsylvania prison. Respondents (N = 177, 84% of unit) completed at least one prison survey and provided network and community role model nominations. RESULTS: Although residents' levels of treatment engagement were significantly correlated with their nominated peers, estimates of peer influence for treatment engagement were non-significant in longitudinal network models. Nor were estimates of peer influence significantly greater for peers perceived as community role models. Rather, inmates connected with peers who were of similar treatment engagement as themselves (i.e., a peer selection process), and the latter primarily resulted from racial homophily in the TC social network. CONCLUSIONS: Inconsistent with the desired treatment model, treatment engagement diffusion was not evident in the sampled TC. Results suggested that highly-engaged residents clustered together at the center of the TC's social structure but had little impact on less-engaged and peripheral inmates. The relatively short (i.e., four-month) program length and moderate-to-low treatment fidelity likely contributed to the lack of peer influence processes.

Social Networks and Health in a Prison Unit.

Although a growing body of research documents lasting health consequences of incarceration, little is known about how confinement affects inmates' health while incarcerated. In this study, we examine the role of peer social integration and prisoners' self-reported health behaviors (smoking, exercise, perception of health, and depression) in a prison unit. We also consider whether inmates with similar health characteristics cluster within the unit. Drawing on a sample of 132 inmates in a "good behavior" unit, we leverage social network data to ask: In prison, is it healthier to become friends with other prisoners or keep your head down and "do your own time"? Using exponential random graph models and community detection methods, findings indicate that social integration is associated with better health outcomes. However, race-ethnicity, religious identity, and exercise intensity emerge as key factors sorting inmates into social groups and likely shaping the distribution of health behaviors observed in the unit.

Sexual intercourse, romantic relationship inauthenticity, and adolescent mental health.

Numerous studies indicate sexual intercourse, especially when it occurs early in adolescence, increases youths' risk of mental health problems. However, no research has examined whether the association between sexual intercourse and mental health varies by romantic relationship inauthenticity, or the level of incongruence between thoughts/feelings and actions within romantic relationships. Using data from a subset of romantically-involved Add Health respondents, we measured sexual involvement in romantic relationships and applied sequence analysis to reports of ideal and actual romantic relationship to measure inauthenticity within adolescent romances. Regressions of depression symptoms indicate that the magnitude of the positive associations between sexual intercourse and girls' mental health is most pronounced in relationships characterized by high levels of relationship inauthenticity and that there is no association between sexual intercourse and girls' depression at low levels of relationship inauthenticity. Having sexual intercourse is positively associated with depression symptoms among boys, but relationship inauthenticity does not alter this association. We discuss the implications of these findings for research on adolescent sexuality and programs aimed at enhancing youth sexuality development.

Where "Old Heads" Prevail: Inmate Hierarchy in a Men's Prison Unit.

Research of inmate social order is a once-vibrant area that receded just as American incarceration rates climbed and the country's carceral contexts dramatically changed. This study reengages inmate society with an abductive mixed methods investigation of informal status within a contemporary men's prison unit. The authors collect narrative and social network data from 133 male inmates housed in a unit of a Pennsylvania medium-security prison. Analyses of inmate narratives suggest that unit "old heads" provide collective goods in the form of mentoring and role modeling that foster a positive and stable peer environment. This hypothesis is then tested with Exponential Random Graph Models (ERGMs) of peer nomination data. The ERGM results complement the qualitative analysis and suggest that older inmates and those who have been on the unit longer are perceived by their peers as powerful and influential. Both analytical strategies point to the maturity of aging and the acquisition of local knowledge as important for attaining informal status in the unit. In sum, this mixed methods case study extends theoretical insights of classic prison ethnographies, adds quantifiable results capable of future replication, and points to a growing population of older inmates as important for contemporary prison social organization.

TOWARD A CRIMINOLOGY OF INMATE NETWORKS.

The mid-twentieth century witnessed a surge of American prison ethnographies focused on inmate society and the social structures that guide inmate life. Ironically, this literature virtually froze in the 1980s just as the country entered a period of unprecedented prison expansion, and has only recently begun to thaw. In this manuscript, we develop a rationale for returning inmate society to the forefront of criminological inquiry, and suggest that network science provides an ideal framework for achieving this end. In so doing, we show that a network perspective extends prison ethnographies by allowing quantitative assessment of prison culture and illuminating basic characteristics of prison social structure that are essential for improving inmate safety, health, and community reentry outcomes. We conclude by demonstrating the feasibility and promise of inmate network research with findings from a recent small-scale study of a maximum-security prison work unit.

Anticipating early fatality: friends', schoolmates' and individual perceptions of fatality on adolescent risk behaviors.

Past research indicates that anticipating adverse outcomes, such as early death (fatalism), is associated positively with adolescents' likelihood of engaging in risky behaviors. Health researchers and criminologists have argued that fatalism influences present risk taking in part by informing individuals' motivation for delaying gratification for the promise of future benefits. While past findings highlight the association between the anticipation of early death and a number of developmental outcomes, no known research has assessed the impact of location in a context characterized by high perceptions of fatality. Using data from Add Health and a sample of 9,584 adolescents (51% female and 71% white) nested in 113 schools, our study builds upon prior research by examining the association between friends', school mates', and individual perceptions of early fatality and adolescent risk behaviors. We test whether friends' anticipation of being killed prior to age 21 or location in a school where a high proportion of the student body subscribes to attitudes of high fatality, is associated with risky behaviors. Results indicate that friends' fatalism is positively associated with engaging in violent delinquency, non-violent delinquency, and drug use after controlling for individual covariates and prior individual risk-taking. Although friends' delinquency accounts for much of the effect of friends' fatalism on violence, none of the potential intervening variables fully explain the effect of friends' fatalism on youth involvement in non-violent delinquency and drug use. Our results underscore the importance of friendship contextual effects in shaping adolescent risk-taking behavior and the very serious consequences perceptions of fatality have for adolescents' involvement in delinquency and drug use.

Gender, Friendship Networks, and Delinquency: A Dynamic Network Approach.

Researchers have examined selection and influence processes in shaping delinquency similarity among friends, but little is known about the role of gender in moderating these relationships. Our objective is to examine differences between adolescent boys and girls regarding delinquency-based selection and influence processes. Using longitudinal network data from adolescents attending two large schools in AddHealth (N = 1,857) and stochastic actor-oriented models, we evaluate whether girls are influenced to a greater degree by friends' violence or delinquency than boys (influence hypothesis) and whether girls are more likely to select friends based on violent or delinquent behavior than boys (selection hypothesis). The results indicate that girls are more likely than boys to be influenced by their friends' involvement in violence. Although a similar pattern emerges for nonviolent delinquency, the gender differences are not significant. Some evidence shows that boys are influenced toward increasing their violence or delinquency when exposed to more delinquent or violent friends but are immune to reducing their violence or delinquency when associating with less violent or delinquent friends. In terms of selection dynamics, although both boys and girls have a tendency to select friends based on friends' behavior, girls have a stronger tendency to do so, suggesting that among girls, friends' involvement in violence or delinquency is an especially decisive factor for determining friendship ties.

Structuring the Future: Anticipated Life Events, Peer Networks, and Adolescent Sexual Behavior.

While prior research has established associations between individual expectations of future events and risk behavior among adolescents, the potential effects of peers' future perceptions on risk-taking have been overlooked. We extend prior research by testing whether peers' anticipation of college completion is associated with adolescent sexual risk-taking. We also examine whether adolescents' perceptions of the negative consequences of pregnancy and idealized romantic relationship scripts mediate the association between peers' anticipation of college completion and sexual risk-taking. Results from multivariate regression models with data from the National Longitudinal Study of Adolescent Health (Add Health) indicate peers' anticipation of college completion is negatively associated with a composite measure of sexual risk-taking and positively associated with the odds of abstaining from sexual intercourse and only engaging in intercourse with a romantic partner (compared to having intercourse with a non-romantic partner). In addition, perceptions of the negative consequences of pregnancy and sexualized relationship scripts appear to mediate a large portion of the association between peers' anticipation of future success and sexual risk-taking and the likelihood of abstaining (but not engaging in romantic-only intercourse). Results from our study underscore the importance of peers in shaping adolescent sexual behavior.

Dating and substance use in adolescent peer networks: a replication and extension.

AIMS: The current report examined associations between romantic partner, peer and individual substance use behaviors in a sample of American adolescents. DESIGN: The report used two waves of data (8th and 9th grades) from the Partnerships to Enhance Resilience (PROSPER) intervention project and focused on dating couples and their friends in 54 sampled school-cohorts. Hierarchical logistic regression models examined the associations between friend, partner and friend-of-partner substance use and daters' future drinking and smoking. SETTING: Surveys administered in rural Pennsylvania and Iowa secondary schools. PARTICIPANTS: A total of 744 dating couples. MEASUREMENTS: Student participants completed questionnaires that assessed substance use, background characteristics and dating and friend nominations. Friend, partner and friend-of-partner substance use were assessed at each wave directly from respective reports. FINDINGS: Consistent with a bridging hypothesis, friends-of-partner drinking had a strong and independent association with subsequent drunkenness (b = 1.40, P < 0.01) and drinking (b = 0.82, P < 0.01) among daters, and these associations did not vary by gender. A similar association was not observed for smoking, where partner (b = 0.77, P < 0.01) and direct friends (b = 1.19, P < 0.05) smoking showed strong and significant associations with future smoking, but friends-of-partner smoking did not (b = -0.44, P > 0.10). CONCLUSION: Romantic partner and peer behaviors have substantially different associations with adolescent drinking and smoking. Intervention efforts aimed at reducing teenage smoking should be aimed at proximal peer and romantic relationships, whereas interventions of teenage drinking should also include the wider circle of indirect friends.

DANGEROUS LIAISONS? DATING AND DRINKING DIFFUSION IN ADOLESCENT PEER NETWORKS.

The onset and escalation of alcohol consumption and romantic relationships are hallmarks of adolescence, yet only recently have these domains jointly been the focus of sociological inquiry. We extend this literature by connecting alcohol use, dating and peers to understand the diffusion of drinking behavior in school-based friendship networks. Drawing on Granovetter's classic concept of weak ties, we argue that adolescent romantic partners are likely to be network bridges, or liaisons, connecting daters to new peer contexts which, in turn, promote changes in individual drinking behaviors and allow these behaviors to spread across peer networks. Using longitudinal data of 459 couples from the National Longitudinal Study of Adolescent Health, we estimate Actor-Partner Interdependence Models and identify the unique contributions of partners' drinking, friends' drinking, and friends-of-partners' drinking to daters' own future binge drinking and drinking frequency. Findings support the liaison hypothesis and suggest that friends-of-partners' drinking have net associations with adolescent drinking patterns. Moreover, the coefficient for friends-of-partners drinking is larger than the coefficient for one's own peers and generally immune to prior selection. Our findings suggest that romantic relationships are important mechanisms for understanding the diffusion of emergent problem behaviors in adolescent peer networks.

Exposure to violence in adolescence and precocious role exits.

Exposure to violence is a serious public health concern that compromises adolescents by affecting their behavior and psychological well-being. The current study advances knowledge about the consequences of exposure to violence in adolescence by applying a life course perspective to evaluate the developmental implications of adolescents' exposure to violence. In particular, drawing on a sample of 11,949 school-aged adolescents in the U.S., we examine whether exposure to violence in adolescence is associated with precocious role exits that some adolescents experience. Exposure to violence is conceptualized as including both direct (i.e., experiencing physical victimization) and indirect exposure (i.e., witnessing others' victimization). Three types of direct exposure to violence are examined: street, intimate partner, and family victimization, as well as four types of indirect exposure including: street, peer, and school violence as well as exposure to family/friend suicide. Using three waves of longitudinal data from the Add Health Study, we find that exposure to violence is associated with greater risks of running away from home, dropping out of high school, having a child, attempting suicide, and coming into contact with the criminal justice system in later adolescence. In addition, risks depend upon the relational context in which the exposure to violence occurred, risks increase with greater exposure to violence, and risks are, for the most part, highest for those youth exposed to both indirect and direct violence in adolescence.
