Anorexia nervosa (AN) is an eating disorder often occurring in adolescence. AN has one of the highest mortality rates amongst psychiatric illnesses and is associated with medical complications and high risk for psychiatric comorbidities, persisting after treatment. Remission rates range from 23% to 33%. Moreover, weight recovery does not necessarily reflect cognitive recovery. This issue is of particular interest in adolescence, characterized by progressive changes in brain structure and functional circuitries, and fast cognitive development. We reviewed existing literature on fMRI studies in adolescents diagnosed with AN, following PRISMA guidelines. Eligible studies had to: (1) be written in English; (2) include only adolescent participants; and (3) use block-design fMRI. We propose a pathogenic model based on normal and AN-related neural and cognitive maturation during adolescence. We propose that underweight and delayed puberty-caused by genetic, environmental, and neurobehavioral factors-can affect brain and cognitive development and lead to impaired cognitive flexibility, which in turn sustains the perpetuation of aberrant behaviors in a vicious cycle. Moreover, greater punishment sensitivity causes a shift toward punishment-based learning, leading to greater anxiety and ultimately to excessive reappraisal over emotions. Treatments combining physiological and neurobehavioral rationales must be adopted to improve outcomes and prevent relapses.

Review
There is growing debate in the parenting literature as to whether using physical punishment to discipline children is an effective strategy or leads to the development of aggressive behaviors and other antisocial attributes. The aim of the current literature review is to examine the association between harsh physical discipline and the development of externalizing behaviors in children, as well as the suggested moderators of this relationship. Secondly, the findings regarding the effects of harsh physical discipline on children's educational outcomes are reviewed. Articles were selected from relevant databases while maintaining an inclusion and exclusion criteria, with a total of 22 articles included in this review. Strong associations between parental corporal punishment and a range of child behaviors were indicated by the literature, and cultural normativeness was implicated as a moderator of these effects. Results regarding the role of parental warmth as a moderator did not provide a firm conclusion. Finally, the findings suggest that when a child is subjected to physical discipline in the home, their life at school may be adversely affected by impaired cognitive performance, peer isolation, and behavioral problems. The primary limitation of the studies reviewed is the use of self-report data and correlational analyses, ruling out the possibility of inferring causal relations. Nonetheless, the results indicate the necessity of encouraging parents and caregivers to avoid physical punishment as a disciplinary tactic while providing them with the tools to explore alternative practices.

Review
BACKGROUND
Studies from multiple contexts conceptualize organized crime as comprising different types of criminal organizations and activities. Notwithstanding growing scientific interest and increasing number of policies aiming at preventing and punishing organized crime, little is known about the specific processes that lead to recruitment into organized crime.
OBJECTIVES
This systematic review aimed at (1) summarizing the empirical evidence from quantitative, mixed methods, and qualitative studies on the individual-level risk factors associated with the recruitment into organized crime, (2) assessing the relative strength of the risk factors from quantitative studies across different factor categories and subcategories and types of organized crime.
METHODS
We searched published and unpublished literature across 12 databases with no constraints as to date or geographic scope. The last search was conducted between September and October 2019. Eligible studies had to be written in English, Spanish, Italian, French, and German.
SELECTION CRITERIA
Studies were eligible for the review if they: Reported on organized criminal groups as defined in this review.Investigated recruitment into organized crime as one of its main objectives.Provided quantitative, qualitative, or mixed methods empirical analyses.Discussed sufficiently well-defined factors leading to recruitment into organized crime.Addressed factors at individual level.For quantitative or mixed-method studies, the study design allowed to capture variability between organized crime members and non-members.
DATA COLLECTION AND ANALYSIS
From 51,564 initial records, 86 documents were retained. Reference searches and experts' contributions added 116 additional documents, totaling 202 studies submitted to full-text screening. Fifty-two quantitative, qualitative, or mixed methods studies met all eligibility criteria. We conducted a risk-of-bias assessment of the quantitative studies while we assessed the quality of mixed methods and qualitative studies through a 5-item checklist adapted from the CASP Qualitative Checklist. We did not exclude studies due to quality issues. Nineteen quantitative studies allowed the extraction of 346 effect sizes, classified into predictors and correlates. The data synthesis relied on multiple random effects meta-analyses with inverse variance weighting. The findings from mixed methods and qualitative studied were used to inform, contextualize, and expand the analysis of quantitative studies.
RESULTS
The amount and the quality of available evidence were weak, and most studies had a high risk-of-bias. Most independent measures were correlates, with possible issues in establishing a causal relation with organized crime membership. We classified the results into categories and subcategories. Despite the small number of predictors, we found relatively strong evidence that being male, prior criminal activity, and prior violence are associated with higher odds of future organized crime recruitment. There was weak evidence, although supported by qualitative studies, prior narrative reviews, and findings from correlates, that prior sanctions, social relations with organized crime involved subjects, and a troubled family environment are associated with greater odds of recruitment.
AUTHORS' CONCLUSIONS
The available evidence is generally weak, and the main limitations were the number of predictors, the number of studies within each factor category, and the heterogeneity in the definition of organized crime group. The findings identify few risk factors that may be subject to possible preventive interventions.

Review
This rapid systematic review describes violence and health outcomes among child domestic workers (CDWs) taken from 17 studies conducted in low- and middle-income countries. Our analysis estimated the median reported rates of violence in CDWs aged 5-17-year-olds to be 56.2% (emotional; range: 13-92%), 18.9% (physical; range: 1.7-71.4%), and 2.2% (sexual; range: 0-62%). Both boys and girls reported emotional abuse and sexual violence with emotional abuse being the most common. In Ethiopia and India, violence was associated with severe physical injuries and sexual insecurity among a third to half of CDWs. CDWs in India and Togo reported lower levels of psycho-social well-being than controls. In India, physical punishment was correlated with poor psycho-social well-being of CDWs [OR: 3.6; 95% CI: 3.2-4; < 0.0001]. Across the studies, between 7% and 68% of CDWs reported work-related illness and injuries, and one third to half had received no medical treatment. On average, children worked between 9 and 15 h per day with no rest days. Findings highlight that many CDWs are exposed to abuse and other health hazards but that conditions vary substantially by context. Because of the often-hidden nature of child domestic work, future initiatives will need to be specifically designed to reach children in private households. Young workers will also benefit from strategies to change social norms around the value and vulnerability of children in domestic work and the long-term implications of harm during childhood.

Corporal punishment is believed to precede various forms of violent behavior, yet prior research has yielded inconsistent findings, partly due to variations in violent types and other factors. This meta-analysis systematically reviewed 35 studies including 144 effect sizes (comprising a total sample size of 159,213) investigating the association between corporal punishment and a spectrum of violent behaviors called Violent Behavior Spectrum (VBS). Additionally, meta-regressions were conducted to explore the moderating impact of punishment severity, violence type and cultural context. Our findings indicated a significant positive relationship between corporal punishment and VBS ( = 0.238, 95%, CI [0.176, 0.300]). Notably, punishment severity was found to influence the strength of this association. Namely, The more severe the corporal punishment, the more likely it is to lead to VBS. These results enhance our understanding of the intricate connection between corporal punishment and various forms of violence, providing valuable insights for both parenting practices and policy development.

Meta-Analysis
IMPORTANCE
Computational psychiatry studies have investigated how reinforcement learning may be different in individuals with mood and anxiety disorders compared with control individuals, but results are inconsistent.
OBJECTIVE
To assess whether there are consistent differences in reinforcement-learning parameters between patients with depression or anxiety and control individuals.
DATA SOURCES
Web of Knowledge, PubMed, Embase, and Google Scholar searches were performed between November 15, 2019, and December 6, 2019, and repeated on December 3, 2020, and February 23, 2021, with keywords (reinforcement learning) AND (computational OR model) AND (depression OR anxiety OR mood).
STUDY SELECTION
Studies were included if they fit reinforcement-learning models to human choice data from a cognitive task with rewards or punishments, had a case-control design including participants with mood and/or anxiety disorders and healthy control individuals, and included sufficient information about all parameters in the models.
DATA EXTRACTION AND SYNTHESIS
Articles were assessed for inclusion according to MOOSE guidelines. Participant-level parameters were extracted from included articles, and a conventional meta-analysis was performed using a random-effects model. Subsequently, these parameters were used to simulate choice performance for each participant on benchmarking tasks in a simulation meta-analysis. Models were fitted, parameters were extracted using bayesian model averaging, and differences between patients and control individuals were examined. Overall effect sizes across analytic strategies were inspected.
MAIN OUTCOMES AND MEASURES
The primary outcomes were estimated reinforcement-learning parameters (learning rate, inverse temperature, reward learning rate, and punishment learning rate).
RESULTS
A total of 27 articles were included (3085 participants, 1242 of whom had depression and/or anxiety). In the conventional meta-analysis, patients showed lower inverse temperature than control individuals (standardized mean difference [SMD], -0.215; 95% CI, -0.354 to -0.077), although no parameters were common across all studies, limiting the ability to infer differences. In the simulation meta-analysis, patients showed greater punishment learning rates (SMD, 0.107; 95% CI, 0.107 to 0.108) and slightly lower reward learning rates (SMD, -0.021; 95% CI, -0.022 to -0.020) relative to control individuals. The simulation meta-analysis showed no meaningful difference in inverse temperature between patients and control individuals (SMD, 0.003; 95% CI, 0.002 to 0.004).
CONCLUSIONS AND RELEVANCE
The simulation meta-analytic approach introduced in this article for inferring meta-group differences from heterogeneous computational psychiatry studies indicated elevated punishment learning rates in patients compared with control individuals. This difference may promote and uphold negative affective bias symptoms and hence constitute a potential mechanistic treatment target for mood and anxiety disorders.

Meta-Analysis Review
Prosocial behaviour is fundamental for our social togetherness. Yet, how acute stress, a common everyday occurrence, influences our behaviours towards one another is still unclear. In this systematic review and meta-analysis, we aimed to quantitatively investigate the effect of experimentally induced acute stress on prosocial behaviours in economic games. We also probed possible moderators to explain differences in findings. We included 23 studies, 77 individual effects, and 2197 participants in the meta-analysis and found no overall differences between stress and control groups in prosocial behaviours (SMD=-0.06), or costly punishment (SMD=-0.11). There were no moderating effects of stressor type, participants' gender/sex, or the delay from the stressor to the task. However, the potential recipient of the donated money (person vs. charity) and the complexity of the decision did reveal some differences under stress. The results of this meta-analysis suggest that there is currently no clear answer to the question of whether or not stress increases or decreases prosociality. We highlight important open questions and suggest where the field should go next.

Review
Seclusion is used in forensic and general mental health settings to protect a person or others from harm. However, seclusion can result in trauma-related harm and re-traumatization with little known about the experience of seclusion for consumers in forensic mental health settings from their perspectives. This article explores consumer experiences of seclusion in forensic mental health settings and explores the differences between female and male experiences of seclusion. Five electronic databases were systematically searched using keywords and variations of experience, attitude, seclusion, coercion, forensic mental health, and forensic psychiatry. Inclusion criteria were original peer-reviewed studies conducted in adult forensic mental health settings reporting data on the experiences of or attitudes towards seclusion. Seven studies met the criteria for inclusion and a quality assessment was undertaken. Results found consumers in forensic mental health settings perceive seclusion to be harmful, a punishment for their behaviour, and largely a negative experience that impacts their emotional health. Some consumers report positive experiences of seclusion. Differences in the experience of seclusion for females and males are unclear. Further research is required to understand the experience of seclusion for women in forensic mental health settings. Identification and consideration of differences in the experience of seclusion for males and females may assist in identifying sex-specific interventions and may inform policy and practices to eliminate or reduce the trauma associated with seclusion use.

Meta-Analysis
BACKGROUND
Housemaids often experience different types of sexual violence by different perpetrators. Sexual violence against housemaids remains usually concealed as victims cannot report such offenses. Except for fragmented studies with varying reports, there is no national prevalence studies conducted on sexual violence among housemaids in Ethiopia. Thus, this systematic review and meta-analysis aimed to determine the pooled prevalence and associated factors of sexual violence amongst housemaids in Ethiopia.
METHODS
A systematic search of PubMed, Embase, Science Direct, HINARI, Scopus, Cochrane Library, and Google Scholar was conducted using relevant search terms. Data were extracted using the Joanna Briggs Institute (JBI) tool. The quality of all selected articles was evaluated using JBI critical appraisal checklist. Data analysis was performed using STATA Version 14 statistical software. Egger's test and funnel plot were used to evaluate publication bias. Heterogeneity was assessed using Cochran's chi-squared test and quantified by I values. A random-effects model was applied during meta-analysis if heterogeneity was exhibited; otherwise, a fixed-effects model was used.
RESULTS
After reviewing 37,849 articles, 8 studies involving 3,324 housemaids were included for this systematic review and meta-analysis. The pooled prevalence of life time sexual violence among housemaids in Ethiopia was 46.26% (95% CI: 24.69, 67.84). The pooled prevalence was 55.43% (95% CI: 26.38, 84.47) for sexual harassment, 39.03% (95% CI: 14.55, 63.52) for attempted rape, and 18.85% (95% CI: 7.51, 30.19) for rape. Sexual violence is more likely among housemaid who previously lived rural residence (AOR = 2.25; 95% CI: 1.41, 3.60), drinks alcohol (AOR = 2.79 95% CI: 1.02, 4.56), and employer alcohol consumption (AOR = 6.01; 95% CI: 1.10, 32.96).
CONCLUSION
This study revealed that the prevalence of sexual violence against housemaids in Ethiopia is high. Of the forms of sexual violence against housemaids, sexual harassment is high. Male employers are the vast majority of perpetrators of their housemaids. Thus, concerned stakeholders should develop and implement interventions that could empower housemaids in their struggle toward the elimination of sexual violence, create awareness for men, control and monitor the implementation of legislation and policies, and prompt punishment of the perpetrators.

Review
UNLABELLED
Resurgence is the return of a previously reinforced response as conditions worsen for an alternative response, such as the introduction of extinction, reductions in reinforcement, or punishment. As a procedure, resurgence has been used to model behavioral treatments and understand behavioral processes contributing both to relapse of problem behavior and flexibility during problem-solving. Identifying existing procedural and analytic methods arranged in basic/preclinical research could be used by basic and preclinical researchers to develop novel approaches to study resurgence, whereas translational and clinical researchers could identify potential approaches to combating relapse during behavioral interventions. Despite the study of resurgence for over half a century, there have been no systematic reviews of the basic/preclinical research on resurgence. To characterize the procedural and analytic methods used in basic/preclinical research on resurgence, we performed a systematic review consistent with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). We identified 120 articles consisting of 200 experiments that presented novel empirical research, examined operant behavior, and included standard elements of a resurgence procedure. We reported prevalence and trends in over 60 categories, including participant characteristics (e.g., species, sample size, disability), designs (e.g., single subject, group), procedural characteristics (e.g., responses, reinforcer types, control conditions), criteria defining resurgence (e.g., single test, multiple tests, relative to control), and analytic strategies (e.g., inferential statistics, quantitative analysis, visual inspection). We make some recommendations for future basic, preclinical, and clinical research based on our findings of this expanding literature.
