A novel expectation-maximization approach to infer general diploid selection from time-series genetic data.

Detecting and quantifying the strength of selection is a main objective in population genetics. Since selection acts over multiple generations, many approaches have been developed to detect and quantify selection using genetic data sampled at multiple points in time. Such time series genetic data is commonly analyzed using Hidden Markov Models, but in most cases, under the assumption of additive selection. However, many examples of genetic variation exhibiting non-additive mechanisms exist, making it critical to develop methods that can characterize selection in more general scenarios. Thus, we extend a previously introduced expectation-maximization algorithm for the inference of additive selection coefficients to the case of general diploid selection, in which heterozygote and homozygote fitnesses are parameterized independently. We furthermore introduce a framework to identify bespoke modes of diploid selection from given data, as well as a procedure for aggregating data across linked loci to increase power and robustness. Using extensive simulation studies, we find that our method accurately and efficiently estimates selection coefficients for different modes of diploid selection across a wide range of scenarios; however, power to classify the mode of selection is low unless selection is very strong. We apply our method to ancient DNA samples from Great Britain in the last 4,450 years, and detect evidence for selection in six genomic regions, including the well-characterized LCT locus. Our work is the first genome-wide scan characterizing signals of general diploid selection.

Working to Improve Youth-Police Interactions: A Pilot Evaluation of a Program for Young People.

In addition to training law enforcement personnel in strategies to promote positive youth-police interactions, equipping youth with similar knowledge is critical in ensuring safe and effective youth-police encounters. The classroom-based Juvenile Justice Curriculum was designed to equip young people with knowledge about the law and their rights and to empower them to have safer interactions with police. In the current study, we conducted the first evaluation of Strategies for Youth's nationally recognized classroom-based intervention. Cross-sectional data were collected from 155 youth (M age = 15.3; 43% White, 23% Black; 61% boys) after they completed the Juvenile Justice Curriculum. Results from our study indicated young people learned new information regarding what leads to arrest and multiple ways they might consider changing their behaviors when interacting with police. Young people's negative experiences with police officers were significantly associated with reduced views that police respect them and reports that they respect police, and with increased views of police as ethnoracially biased after completing the program. Altogether, our pilot program evaluation of this program demonstrated increased awareness of what constitutes illegal behavior, program engagement, and learned strategies to improve future interactions with police. Findings highlight the importance of policy makers supporting programming like the Juvenile Justice Curriculum as one means of preventing juvenile legal system involvement. While the onus to ensure safe and effective interactions with police should not be on young people, empowering young people to understand the law and their rights may help improve the social climate surrounding community responses to police and police interactions.

Did George Floyd's murder shape the public's felt obligation to obey the police?

OBJECTIVE: Our goal in the present study was to use longitudinal data to assess how normative (i.e., consensually motivated) and instrumental (i.e., coercively motivated) obligation to obey police changed after police murdered George Floyd and whether these changes differed by political ideology. HYPOTHESES: Using procedural justice theory, we hypothesized that after Floyd's murder, participants would feel less normatively obligated and more instrumentally obligated to obey police. We also hypothesized that these trends would be stronger for liberal-leaning than conservative-leaning participants. METHOD: Adults (N = 645) were recruited through Prolific from four politically diverse U.S. states. Participants reported their normative and instrumental obligation across three waves of data collection, each separated by 3 weeks. The first two waves were collected prior to the Floyd's murder, and the third was collected after. RESULTS: Hierarchical linear models indicated that although normative obligation remained stable before Floyd's murder, it declined after Floyd's murder (b = -0.19, 95% CI [-0.24, -0.14], p < .001). In contrast, coercive obligation to obey increased consistently across all three waves. Liberal-leaning participants drove most of the effects. CONCLUSIONS: For researchers, these findings help strengthen our understanding of procedural justice theory by differentiating normative and instrumental obligation and by distinguishing differences by political ideology within the context of a historic police-brutality event. For policymakers and law enforcement, our research suggests that police brutality may undermine the public's normative felt obligation to obey the police, which would be problematic for police reformation efforts grounded in governing by mutual consent versus by fear and coercion.

Centering race in procedural justice theory: Structural racism and the under- and overpolicing of Black communities.

OBJECTIVE: We assessed the factors that legitimized the police in the United States at an important moment of history, just after the police killing of George Floyd in 2020. We also evaluated one way of incorporating perceptions of systemic racism into procedural justice theory. HYPOTHESES: We tested two primary hypotheses. The first hypothesis was that perceptions of police procedural justice, distributive justice, and bounded authority were important to the legitimization of the police. The second hypothesis was that perceptions of the under- and overpolicing of Black communities also mattered to the delegitimization of the institution, especially for people who identified with the Black Lives Matter movement. METHOD: A cross-sectional quota sample survey of 1,500 U.S. residents was conducted in June 2020. Data were analyzed using confirmatory factor analysis, structural equation modeling, and latent moderated structural equation modeling. RESULTS: People who viewed the police as legitimate also tended to believe that police treated people with respect and dignity, made decisions in unbiased ways, fairly allocated their finite resources across groups in society, and respected the limits of their rightful authority. Moreover, people who believed that Black communities were underpoliced and overpoliced also tended to question the legitimacy of the police, especially if they identified with the Black Lives Matter movement. These results held among Black and White study participants alike. CONCLUSIONS: At the time of the study, systemic racism in policing may have delegitimized the institution in a way that transcended the factors that procedural justice theory focuses on, such as procedural justice. This was especially so for individuals who identified with a social movement, Black Lives Matter, that had an extremely high profile in 2020.

The intergenerational effects of paternal incarceration on children's social and psychological well-being from early childhood to adolescence.

The present study sought to unravel the psychological processes through which mass incarceration, specifically paternal incarceration, is negatively affecting the next generation of children. Data came from 4,327 families from 20 cities who participated in a 10-year longitudinal study. Parents and children reported on children's rule-breaking behaviors and depressive symptoms when they were on average ages 5 (2003-2006), 9 (2007-2010), and 15 (2014-2017). Parental surveys and disposition information were combined to assess paternal incarceration at each age. Results showed that children who experienced paternal incarceration at age 5 also demonstrated more rule-breaking behaviors at age 15. Children's age-9 depressive symptoms partially mediated our finding, such that children who experienced paternal incarceration at age 5 also showed greater depressive symptoms at age 9, which in turn predicted greater rule-breaking behaviors at age 15. Paternal incarceration predicted future rule-breaking behaviors more strongly than did other forms of father loss. Because we found paternal incarceration during childhood is associated with worsened adjustment into adolescence, we discussed the need for developmentally appropriate practices in the criminal justice system.

A Network Approach to Compliance: A Complexity Science Understanding of How Rules Shape Behavior.

To understand how compliance develops both in everyday and corporate environments, it is crucial to understand how different mechanisms work together to shape individuals' (non)compliant behavior. Existing compliance studies typically focus on a subset of theories (i.e., rational choice theories, social theories, legitimacy theories, capacity theories, and opportunity theories) to understand how key variables from one or several of these theories shape individual compliance. The present study provides a first integrated understanding of compliance, rooted in complexity science, in which key elements from these theories are considered simultaneously, and their relations to compliance and each other are explored using network analysis. This approach is developed by analyzing online survey data (N = 562) about compliance with COVID-19 mitigation measures. Traditional regression analysis shows that elements from nearly all major compliance theories (except for social theories) are associated with compliance. The network analysis revealed groupings and interconnections of variables that did not track the existing compliance theories and point to a complexity overlooked in existing compliance research. These findings demonstrate a fundamentally different perspective on compliance, which moves away from traditional narrow, non-network approaches. Instead, they showcase a complexity science understanding of compliance, in which compliance is understood as a network of interacting variables derived from different theories that interact with compliance. This points to a new research agenda that is oriented on mapping compliance networks, and testing and modelling how regulatory and management interventions interact with each other and compliance within such networks.

Cross-Theoretical Compliance: An Integrative Compliance Analysis of COVID-19 Mitigation Responses in Israel.

To understand the question why people obey or break rules, different approaches have focused on different theories and subsets of variables. The present research develops a cross-theoretical approach that integrates these perspectives. We apply this in a survey of compliance with COVID-19 pandemic mitigation rules in Israel. The data reveal that compliance in this setting was shaped by a combination of variables originating from legitimacy, capacity, and opportunity theories (but not rational choice or social theories). This demonstrates the importance of moving beyond narrow theoretical perspectives of compliance, to a cross-theoretical understanding-in which different theoretical approaches are systematically integrated.

Adolescents' views of defunding the police, abolishing the police, and "The Talk".

INTRODUCTION: Definitions regarding defunding or abolishing the police are highly contested in the United States. Moreover, adolescents' definitions and how socialization processes shape their definitions are unclear. METHODS: Within a national sample of 822 adolescents ages 13-17 (49.69% female; 63.22% White, 16.93% Black/African American, 11.01% Hispanic/Latinx) surveyed in July 2020, this study examined how youth define defunding versus abolishing the police, how much parents talk to youth about the police (i.e., "the Talk"), and whether relations emerged between defunding/abolishing the police and "the Talk." RESULTS: Youth supported defunding more than abolishing (d = 0.57). Support for abolishing was higher for youth who frequently received "the Talk" (b = 0.25). Differences by race and gender were uncovered in how frequently youth received "the Talk." CONCLUSIONS: Police must recognize that coercion, fear, and biased policing breed discontent and promote families to engage in protective parenting strategies including engaging in "the Talk."

The Longitudinal Associations Between Paternal Incarceration and Family Well-Being: Implications for Ethnic/Racial Disparities in Health.

OBJECTIVE: Ethnic/racial minority children in the United States are more likely to experience father loss to incarceration than White children, and limited research has examined the health implications of these ethnic/racial disparities. Telomere length is a biomarker of chronic stress that is predictive of adverse health outcomes. This study examined whether paternal incarceration predicted telomere length shortening among offspring from childhood to adolescence, whether maternal depression mediated the link, and whether ethnicity/race moderated results. METHOD: Research participants included 2,395 families in the Fragile Families and Child Wellbeing study, a national and longitudinal cohort study of primarily low-income families from 20 large cities in the United States. Key constructs were measured when children were on average ages 9 (2007-2010) and 15 (2014-2017). RESULTS: Children who experienced paternal incarceration exhibited shorter telomere lengths between ages 9 and 15, and changes in maternal depression mediated this finding. Specifically, mothers who experienced a partner's incarceration were more likely to have depression between children's ages 9 and 15. In turn, increases in maternal depression between children's ages 9 and 15 predicted more accelerated telomere length shortening among children during this period. Paternal incarceration was more prevalent and frequent for ethnic/racial minority youth than for White youth. CONCLUSION: Paternal incarceration is associated with a biomarker of chronic stress among children in low-income families. Rates of paternal incarceration were more prevalent and frequent among Black American and multiethnic/multiracial families than among White Americans. As a result, the mass incarceration crisis of the criminal justice system is likely shaping intergenerational ethnic/racial health disparities.

Perceptions of Legal Authorities in a Longitudinal Study of Adjudicated Youth.

While perceptions of the legitimacy of formal authority have been found to influence offending, little is known about the extent to which such perceptions influence the related outcome of victimization. This study addressed this gap by examining how changes in legitimacy affected victimization both within- and between-individuals. This study used 7 waves of the Pathways to Desistance data (n = 1310; 13.85% female; age range 14-22). Youth who have committed serious offenses were surveyed at 6-month intervals during the transition from adolescence to young adulthood. In the full sample, the effects of legitimacy on both victimization and offending remained largely stable over time within individuals. Sensitivity analyses revealed that more positive perceptions of legitimacy significantly reduce offending for boys and reduce victimization for girls during the developmental period under study. Consistent with prior research, between-individual differences appear to be more important than within-individual change for explaining both offending and victimization. The implications of the results for theory, future research, and early intervention for high-risk youth are discussed.

Social distancing in America: Understanding long-term adherence to COVID-19 mitigation recommendations.

A crucial question in the governance of infectious disease outbreaks is how to ensure that people continue to adhere to mitigation measures for the longer duration. The present paper examines this question by means of a set of cross-sectional studies conducted in the United States during the COVID-19 pandemic, in May, June, and July of 2020. Using stratified samples that mimic the demographic characteristics of the U.S. population, it seeks to understand to what extent Americans continued to adhere to social distancing measures in the period after the first lockdown ended. Moreover, it seeks to uncover which variables sustained (or undermined) adherence across this period. For this purpose, we examined a broad range of factors, relating to people's (1) knowledge and understanding of the mitigation measures, (2) perceptions of their costs and benefits, (3) perceptions of legitimacy and procedural justice, (4) personal factors, (5) social environment, and (6) practical circumstances. Our findings reveal that adherence was chiefly shaped by three major factors: respondents adhered more when they (a) had greater practical capacity to adhere, (b) morally agreed more with the measures, and (c) perceived the virus as a more severe health threat. Adherence was shaped to a lesser extent by impulsivity, knowledge of social distancing measures, opportunities for violating, personal costs, and descriptive social norms. The results also reveal, however, that adherence declined across this period, which was partly explained by changes in people's moral alignment, threat perceptions, knowledge, and perceived social norms. These findings show that adherence originates from a broad range of factors that develop dynamically across time. Practically these insights help to improve pandemic governance, as well as contributing theoretically to the study of compliance and the way that rules come to shape behavior.

Perceptions of police legitimacy and bias from ages 13 to 22 among Black, Latino, and White justice-involved males.

OBJECTIVE: Although researchers, policymakers, and practitioners recognize the importance of the public's perceptions of police, few studies have examined developmental trends in adolescents and young adults' views of police. HYPOTHESES: Hypothesis 1: Perceptions of police legitimacy would exhibit a U-shaped curve, declining in adolescence before improving in young adulthood. Hypothesis 2: At all ages, Black youth would report more negative perceptions of police legitimacy than Latino youth, who would report more negative perceptions than White youth. Hypothesis 3: Perceptions of police bias would be consistently associated with worse perceptions of police legitimacy. METHOD: Utilizing longitudinal data from the Crossroads Study, this study examined within-person trends in males' perceptions of police legitimacy from ages 13 to 22, as well as whether perceptions of police bias were associated with perceptions of police legitimacy. RESULTS: Perceptions of police legitimacy followed a U-shaped curve that declined during adolescence, reached its lowest point around age 18, and improved during the transition to young adulthood. Compared with White youth, Latino and Black youth had shallower curves in perceptions of police legitimacy that exhibited less improvement during the transition to adulthood. Further, perceptions of police bias were consistently associated with more negative perceptions of police legitimacy across races and ages. CONCLUSIONS: While perceptions of police legitimacy may decline during adolescence before improving during the transition to adulthood, perceptions of police bias are consistently negatively related to youth and young adults' perceptions of police legitimacy.

Crossroads in juvenile justice: The impact of initial processing decision on youth 5 years after first arrest.

The current study advances past research by studying the impact of juvenile justice decision making with a geographically and ethnically diverse sample (N = 1,216) of adolescent boys (ages 13-17 years) for the 5 years following their first arrest. Importantly, all youth in the study were arrested for an eligible offense of moderate severity (e.g., assault, theft) to evaluate whether the initial decision to formally (i.e., sentenced before a judge) or informally (i.e., diverted to community service) process the youth led to differences in outcomes. The current study also advanced past research by using a statistical approach that controlled for a host of potential preexisting vulnerabilities that could influence both the processing decision and the youth's outcomes. Our findings indicated that youth who were formally processed during adolescence were more likely to be re-arrested, more likely to be incarcerated, engaged in more violence, reported a greater affiliation with delinquent peers, reported lower school enrollment, were less likely to graduate high school within 5 years, reported less ability to suppress aggression, and had lower perceptions of opportunities than informally processed youth. Importantly, these findings were not moderated by the age of the youth at his first arrest or his race and ethnicity. These results have important implications for juvenile justice policy by indicating that formally processing youth not only is costly, but it can reduce public safety and reduce the adolescent's later potential contributions to society.

Exposure to Gun Violence: Associations with Anxiety, Depressive Symptoms, and Aggression among Male Juvenile Offenders.

Objective: To examine whether at-risk male youth experience increases in anxiety, depressive symptoms, and aggression during years when they are exposed to gun violence, adjusting for relevant covariates.Method: Participants were 1,216 male, justice-involved adolescents who were recently arrested for the first time for a moderate offense. They were interviewed 9 times over 5 years. Fixed effects (within-individual) regression models were used to estimate concurrent associations between exposure to gun violence and three outcomes: depressive symptoms, anxiety symptoms, and aggression (both overall and separately for proactive and reactive aggression). The reverse direction (anxiety, depressive symptoms, and aggression predicting gun violence exposure) was also modeled.Results: After controlling for covariates, exposure to gun violence was significantly associated with increases in reactive aggression and, to a lesser extent, increases in proactive aggression. In addition, gun violence exposure was associated with increased anxiety but not depressive symptoms. We found no support for the reverse direction.Conclusions: At-risk males experienced significant increases in anxiety and aggression (particularly reactive aggression) during years when they are exposed to gun violence, even after accounting for several potential confounding factors. The greater impact on reactive aggression suggests that exposure to gun violence may affect self-regulation and/or social information processing. The analyses shed light on the less-visible damage wrought by gun violence and underscore the importance of mental health screening and treatment for youth who have been exposed to violence - especially gun violence - both to assist individual youths and to disrupt cycles of violence.

Dynamic Risk Factors for Handgun Carrying: Are There Developmental or Sex Differences?

Objective: This study examines the effects of dynamic risk factors on handgun carrying from adolescence into young adulthood.Method: A nationally representative sample of 8,679 individuals (ages 12-26; 51.1% male; 58% White, 26.8% African American; 21.2% Hispanic ethnicity) from the National Longitudinal Survey of Youth (1997 cohort) interviewed at least three times across nine annual waves is used to estimate effects on handgun carrying. Key predictors include gang membership, selling and using drugs, violent crime, and arrest. Using mixed effects models, we focus on within-individual effects across three timeframes from ages 12 to 26: 1) predictors and handgun carrying measured concurrently, 2) predictors measured across one year and handgun carrying measured in the final month of the same year, and 3) predictors measured in the wave before handgun carrying. We also contrast estimates by sex and age.Results: All theoretically relevant predictors statistically significantly predict handgun carrying across the first two timeframes. However, none are statistically significant predictors of handgun carrying in the following year. Few significant sex and age differences emerge.Conclusions: Handgun carrying is an ephemeral behavior particularly during adolescence. The predictors of handgun carrying, which are grounded in gangs, drug use/sale, and crime involvement, appear to have short-term impacts that are consistent across age as well as across sex. Consequently, future work should focus on shorter-term changes in models and there is no evidence that intervention efforts must take fundamentally different approaches to reduce handgun use among males versus females or adolescents versus adults.

Partners or adversaries? The relation between juvenile diversion supervision and parenting practices.

OBJECTIVE: Based on guiding principles such as parens patriae, juvenile probation officers (JPOs) not only supervise youth, but in certain jurisdictions they also decide how control-oriented their conditions will be. JPOs' perceptions of parenting could be related to their decision making. This study examined: (a) whether JPOs' perceptions of the home were associated with the conditions they placed on youth; (b) if JPOs' perceptions of the home aligned with the youths' perceptions; and (c) if JPOs' control-oriented conditions were associated with changes in parenting practices. HYPOTHESES: (H1) JPOs' perceptions of the home should be positively related to youths' perceptions of parenting practices. (H2) JPOs' perceptions of the home should be positively associated with the conditions imposed. (H3) JPOs' control-oriented conditions may be positively associated with increased parental supervision, yet they may also be associated with lessened parental supervision. METHOD: The sample consisted of 265 male youth (mean age = 15.41; 76.6% Latino, 19.25% White, 0.75% Black) who were arrested for the first time and placed on supervised diversion. RESULTS: Latent class analyses indicated that there were three supervision conditions classes: standard, moderate, and high control. JPOs' perceptions of the home did not align with youths' perceptions of parenting practices (e.g., rule setting, curfew setting, and monitoring) yet they were the strongest predictor of receiving the most control-oriented conditions. Surprisingly, parental rule setting, curfew setting, and monitoring declined once youth were placed under supervision, and declines did not differ based on how control-oriented their official conditions were. CONCLUSIONS: Parents are thought to be vital in justice-involved youths' success. Yet within this sample, officers' perceptions of the family did not align with youths' perceptions. Further, parental supervision declined equally regardless of how control-oriented youths' supervision conditions were. Parents must be better integrated into the process to enhance the success of youth on community supervision. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Trust and Discipline: Adolescents' Institutional and Teacher Trust Predict Classroom Behavioral Engagement following Teacher Discipline.

This daily diary study examined how adolescents' institutional and teacher-specific trust predicted classroom behavioral engagement the day after being disciplined by that teacher. Within mathematics classrooms, adolescents (N = 190; Mage  = 14 years) reported institutional and teacher-specific trust and then completed a 15-day diary assessing teacher discipline and behavioral engagement. The results indicated that, among adolescents with low teacher trust, discipline was unrelated to next-day behavior. Contrastingly, adolescents with high teacher but low institutional trust became less engaged following discipline, whereas those with high teacher and institutional trust became more engaged. These findings suggest that adolescents interpret discipline within the social context of trust, and adolescents' trust in the institution and teacher are important for discipline to improve behavior.

The Relation Between Callous-Unemotional Traits, Psychosocial Maturity, and Delinquent Behavior Among Justice-Involved Youth.

Callous-unemotional (CU) traits are a risk factor for severe and persistent patterns of juvenile delinquency. Given the influence of CU trait assessments in justice-system settings, it is important to determine whether the predictive utility of CU traits is conditional on the absence of protective psychosocial factors. Employing a sample of justice-involved male youth (N = 1,216, Mage  = 15.29), this study examined whether psychosocial maturity (PSM) outweighs or attenuates the effect of CU traits on delinquency. Results indicated that youth with high CU traits or low PSM offended more during the year following their first arrest. Additionally, PSM moderated the relation between CU traits and offending, such that higher PSM was associated with less offending but only among low CU youth.

DO POSITIVE PERCEPTIONS OF CORRECTIONAL STAFF MITIGATE INSTITUTIONAL VIOLENCE AMONG YOUTHFUL OFFENDERS?

Juvenile justice facilities can be dangerous places for adolescents and may promote violent behavior among incarcerated youth. With high rates of violence among detained juveniles, youth who do not feel safe may resort to violent behavior to protect themselves. However, this "cycle of violence" may be interrupted if youth can turn to correctional staff for support. Using a 3-wave, longitudinal sample of 373 male incarcerated adolescents, the results indicated that as compared to violence exposure prior to incarceration, exposure to institutional violence more strongly predicts violent behavior. Further, the findings indicated that perceptions of staff serve as a buffer to violence exposure and may interrupt the cycle of violence. Policy implications are discussed.

Under the radar or under arrest: How is adolescent boys' first contact with the juvenile justice system related to future offending and arrests?

This study examined the extent to which being arrested during adolescence was associated with subsequent self-reported offending and court-recorded arrests. We also examined whether the way in which the justice system processed adolescents was related to the nature of these associations. The sample included 532 boys who had been arrested ("justice-system-involved") and 99 boys who had never been arrested despite engaging in similar illegal behaviors ("no-justice-system-contact"). Data included official arrest records and youths' self-reported illegal behavior at a baseline interview and a follow-up 6 months later. To reduce group differences at baseline, we calculated matching weights with 2 dozen variables and used these weights in all analyses. Results demonstrated that the groups differed in their rate of change in self-reported offending between the 2 interviews and in their likelihood of being arrested during the study period. The no-justice-system-contact group self-reported the same amount of offending at baseline and the follow up, whereas the justice-system-involved youth who received the most lenient disposition (i.e., sanction and dismiss) decreased their self-reported violent, theft or property, and total offending, and the justice-system-involved youth who received the most punitive disposition (i.e., adjudication) increased their self-reported violent offending. All justice-system-involved youth were more likely to be arrested during the study period than the no-justice-system-contact youth, even after accounting for self-reported offending. Thus, even though some justice system interventions were associated with less subsequent offending, involvement with the juvenile justice system during adolescence, in and of itself, is a significant risk factor for repeated contact with the system.
