Solitary confinement and the well-being of people in prison.

BACKGROUND: Solitary confinement and mental well-being has been researched extensively, with a significant increase in studies over the last ten years. These recent studies produce mixed evidence for whether placement in solitary confinement is associated with psychological distress. We advance our understanding of these relationships in two critical ways. First, we conduct both between- and within-person analyses within the same data to better understand the relationship of solitary confinement and mental well-being relative to the well-being of people in less restrictive prison settings. Second, we ask the men in our sample questions about their personality style, coping strategies, and interactions with staff, which allows us to explore how individual characteristics and prison experiences matter, alongside isolation, in understanding mental well-being. METHODS: We gather data from interviews at three time points with 122 men in solitary confinement and 204 men in other conditions of confinement in Arizona from 2017 to 2019. We merge these interview data with administrative data on study sample and population sample to include critical measures such as mental health score, risk level, and visitation status. Our interviews contain a Global Severity Index (GSI), created from 90 self-reported psychopathological symptoms experienced, that we use to assess well-being. We estimate cross-classified multilevel models to assess between-person differences and within-person change in well-being over time. RESULTS: There was a small relationship between solitary confinement and worsening well-bring (longitudinal, within-person) and a small relationship between solitary confinement and worse well-being (cross-sectional, between-person), with this between-person association reduced significantly upon inclusion of additional individual characteristics and prison experiences. CONCLUSIONS: Our results suggest that the incarceration experience, including conditions of confinement, is associated with mental well-being in different ways for different people. We believe that collective confinement and well-being could receive the same scholarly attention and public concern as solitary confinement.

Treatment engagement in a prison-based Therapeutic Community: A mixed-methods approach.

Given the high proportion of inmates with histories of substance use disorders in the era of mass incarceration, many correctional institutions have integrated the prison-based Therapeutic Community (TC) into their programming. While most evaluations provide evidence of lowered rates of relapse and recidivism, the majority of TC graduates still have negative outcomes post-release. Filling an important gap in the TC treatment literature, we analyze quantitative measures of treatment engagement alongside qualitative narratives from prison-based TC residents, providing an essential look into the black box of TC treatment mechanisms. Quantitative results show more between-person variation than within-person change, reflecting trivial increases in treatment engagement throughout time in the program. Qualitative results unpack these findings, pointing to processes of selection bias, heterogeneous treatment effects, and program fidelity lapses. In combination, our mixed data identify tangible modifications to program implementation that could strengthen desired post-release outcomes.

On the positive relationship between breastfeeding & intelligence.

A wealth of literature has examined the association between breastfeeding and the development of cognitive abilities in childhood. In particular, at least some evidence exists suggesting that breastfed children perform better on measures of intelligence later in life. Although a correlation appears to be present, fewer observational studies have included appropriate adjustment for potentially confounding variables; maternal intelligence, maternal education, and cognitive stimulation provided by mothers being chief among them. As a result, we analyze a national sample of approximately 790 American respondents to test the association between breastfeeding and intelligence during childhood and adolescence using multiple intelligence tests and controlling for a range of key covariates. Our results suggest that the correlation between breastfeeding throughout the first six months of life and intelligence is statistically significant and consistent, yet of substantively minor impact.

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.

"Role magnets"? An empirical investigation of popularity trajectories for life-course persistent individuals during adolescence.

Recent scholarship has focused on the role of social status in peer groups to explain the fact that delinquency is disproportionately committed during adolescence. Yet, the precise mechanism linking adolescence, social status, and antisocial behavior is not well understood. Dual-taxonomy postulates a testable mechanism that links the sudden increase in risky behavior among adolescents to the social magnetism of a small group of persistently antisocial individuals, referred to here as the "role magnet" hypothesis. Using semi-parametric group-based trajectory modeling and growth-curve modeling, this study provides the first test of this hypothesis by examining physical violence and popularity trajectories for 1,845 male respondents age 11-32 from a nationally representative sample (54 % non-Hispanic White; 21 % non-Hispanic African American; 17 % Hispanic; 8 % Asian). Individuals assigned to a "chronic violence" trajectory group showed consistently lower average levels of popularity from 11 to 19. But, these same individuals experienced increases in popularity during early adolescence and subsequent declines in late adolescence. These findings are linked to current research examining social status as a mechanism generating antisocial behavior during adolescence and the consequences of delayed entry into adult roles.

The context of control: a cross-national investigation of the link between political institutions, efficacy, and collective action.

Most research on efficacy and participation in collective action has focused on single country samples with little attention paid to the relationship between efficacy and country-level structural factors. Drawing on value expectancy theory, we theorize a link between macro-level political institutions and micro-level efficacy. To address the previous limitations in the efficacy and collective action literature, we use multi-level, cross-national data, and present results from a series of hierarchical models testing whether efficacy increases collective action cross-nationally, whether political institutions affect efficacy, and whether the effect of efficacy on collective action is conditional on political institutions. We find that efficacy increases collective action, that certain political institutions increase efficacy, and that the effect of efficacy on collective action is partly conditional on the inclusiveness of a country's political institutions. These findings suggest the insufficiency of purely structural as well as social psychological explanations of collective action.

Thyroxine-induced alterations in the testis and seminal vesicles of air-breathing catfish, Clarias gariepinus.

Effect of experimentally induced thyroxine overdose on the testis and seminal vesicles was studied in the air-breathing catfish, Clarias gariepinus during the preparatory and the pre-spawning phase. The present study revealed a marked reduction in testosterone level in serum, testis and seminal vesicles (SV). Histological examination showed a considerable reduction in the number of spermatozoa/spermatids in the seminiferous tubular lumen as well as depletion of fluid in the loculi of SV. SDS-PAGE analysis of SV fluid proteins demonstrated a significant decrease in the level of a ~27 kDa protein in thyroxine treated fishes. Evidences are presented here to indicate that thyroid hormone plays a role in regulating testis and SV function in catfish.
