Aggression and Violent Behavior最新文献

Research from around the world shows that violent crime is spatially clustered in hot spots. A growing body of research shows that place-based changes to the built environment can help reduce violent crime. Increasingly, research summaries imply there are important public health approaches to reduce the hyper-concentration of violence. Past summaries of the effect of place-based changes on violence have focused primarily on their overall effect and have not paid adequate attention to the impact on violent crime within hot spots. Additionally, research summaries seldom delineate what place-based changes actually involve the work of public health departments versus that of housing agencies, redevelopment authorities, street departments, or community-based nonprofits. This review focuses on evidence from experimental and quasi-experimental studies of placed-based changes to the built environment that focus on violent crime hot spots. A narrative review discusses the context of each intervention and assesses their effect sizes on violent crime. Implications for this evidence for public health approaches to reduce violent crime hot spots are considered.

Aggressive behavior is a multifaceted phenomenon encompassing various behaviors with distinct etiological, developmental, and motivational underpinnings. Reactive aggression is impulsive, emotionally charged, and triggered by real or perceived provocation, whereas proactive aggression is premeditated, controlled, and aimed at achieving specific goals. This review delves into the physiological aspects of aggression to explore the validity of the “hot-blooded” (reactive) versus “cold-blooded” (proactive) distinction, which are thought to be associated with hyper-arousal and hypo-arousal, respectively. To do so, we build on evidence from work investigating the role of heart rate (HR), skin conductance (SC), heart rate variability (HRV), and respiratory sinus arrhythmia (RSA) in the manifestation of reactive and proactive aggression. Our review points to contradicting findings in terms of the physiological arousal patterns associated with each aggressive behavior, although associations with HRV and RSA were more consistent compared to those found for HR and SC measures. We propose distinct possibilities that might explain the identified contradictory evidence. Specifically, we suggest that future research needs to test for (1) environmental moderation (e.g., parenting styles), (2) individual differences (e.g., negative emotionality and callous-unemotional traits), (3) potential associations with physiological responses to threat (e.g., fear conditioning and startle reactivity), and (4) the interaction between sympathetic and parasympathetic nervous systems. Despite its limitations, this line of work also has important implications and can guide more effective interventions for aggressive individuals who operate at a high cost to peers, family members and to the society in general.

Recent decades have seen substantial research on the biology of childhood aggression. Here, we review whether and how insights from biological research have contributed to more effective treatments for aggression, with a focus on parenting interventions. We also outline specific strategies for researchers to integrate biological and clinical approaches to refine or augment parenting-focused interventions moving forward. In particular, we (1) evaluate the ability of biological data to provide unique and treatment-relevant insights into the mechanisms of aggression, beyond behavioral data; (2) outline ways of incorporating biological measures directly into clinical practice and possible drawbacks; and (3) discuss the privileged position of biological evidence in the eyes of policymakers and the public, including the potential to drive change at the risk of promoting biological essentialism. To meaningfully advance parenting interventions for childhood aggression, clinical scientists must be thoughtful about the promises and possible pitfalls of integrating biological and implementation-oriented approaches.

The alarming prevalence of workplace violence and harassment (WVH) has serious repercussions for individuals, workplaces, and broader societies. As scholarly interest in WVH intensifies, evidenced by a burgeoning number of studies, a comprehensive overview becomes pivotal, especially in discerning effective prevention and intervention methods. Addressing this, the present study aimed to synthesize the vast array of knowledge, focusing on globally applicable insights for diverse organizational settings. The research was structured in two interlinked phases. In the initial phase, a thorough cross-disciplinary literature search identified five pivotal umbrella reviews on WVH, providing insights into prevalence, risk factors, outcomes, and intervention strategies. These studies spanned the years 2001 to 2022. The subsequent phase undertook an umbrella review of nine synthesis studies, specifically centered on WVH interventions, covering research from 1992 to 2021. Data analysis was performed using a systematic review methodology, following PRISMA guidelines to ensure structured and comprehensive identification and analysis of relevant studies. Results spotlighted certain interventions as notably more impactful. Considering WVH's multifaceted nature, the current study findings support the need for interventions that are multilevel, multitarget, and multicomponent. Among the findings highlighted is the importance of leadership commitment in both implementing successful interventions and fostering a culture of transformation. This study provides researchers and practitioners with an enhanced understanding of WVH and its prevention.

Sexual offending represents a significant societal burden and a critical public health concern due to its devastating impact on victims. Extensive research on the etiology and maintenance of sexual offending has led to the development of several hypotheses. Among these, a compelling hypothesis suggests that a putative deficit in emotional recognition skills may underlie the genesis of aggressive behavior, including acts of sexual assault against both adults and children. However, previous studies have reported heterogeneity in emotion recognition skills across different subtypes of offending behavior.

The aim of this systematic review was to determine whether adult sexual offenders (ASO), pedophile diagnosed offenders (PED), and pedophile non-diagnosed offenders (N-PED) share a common deficit in facial emotion recognition.

A systematic literature search was conducted using the PRISMA guidelines. A total of 13 studies were included that met the following inclusion criteria: inclusion of sex offenders and a control group, and original measurement of facial emotion recognition using a validated face battery.

The results indicate a reduced ability to recognize facial emotions in ASO offenders. However, no differences emerged between PED and N-PED offenders and controls. Moreover, this review highlights the difficulties of homogenizing and implementing a systematic assessment of the sex offender population. Factors such as psychiatric/personality disorders, medications and victim characteristics have been particularly understudied in relation to offender etiology and their potential influence on emotional processing. We have therefore formulated basic recommendations for systematizing sexual offender screening in future studies investigating emotional processing in forensic populations.

Despite over 50 years of research, limited evidence exists regarding a connection between pornography and sexual offending, which individuals are most likely to be affected by pornography, and the broader implications of this purported relationship. Prior meta-analyses have included studies that use a wide range of different methodologies but have not isolated the effects of pornography in samples of individuals that perpetrated a sex offense. We examined the association between pornography (only legal content, child sexual abuse material was not included) and sexual offending in studies that included samples of individuals that had admitted to or been convicted of a sex offense (persons identified as committing a sexual offense (s); PISOs). In addition, we examined several potentially relevant moderator variables that could impact the relationship between pornography and sex offending. Using Robust Variance Estimation, the main effect was non-significant, g = 0.18, 95 % CI [−0.09, 0.46], which further questions whether pornography is associated with various offender populations. However, several moderator analyses generated significant results, including method used to identify PISOs and living status (institutionalized versus living in the community). Tentative conclusions based on these results are discussed, along with implications for future research.

Our paper reports on a systematic review of crime concentration studies over the last 35 years. We identify 47 papers that report on crime concentrations at a micro geographic unit of analysis. These papers produced 49 estimates of general crime concentration for crime incidents at streets segments for a specific cumulative proportion of crime. The median concentration for these estimates is 50 % of crime found at 4.5 % of streets, and 25 % of crime at 1.25 % of streets. The bandwidth for 50 % crime concentration is 9.3 % (1.7–11.0 %), and for 25 % crime concentration 3.0 % (0.4–3.4 %). Using the interquartile range to exclude outliers, we found a bandwidth of 2.5 % (3.2–5.7 %) for 50 % of crime, and 1.4 % (0.8–2.2 %) for 25 % of crime. Crime concentration was generally stronger for specific types of crime, and bandwidths of concentration were generally smaller. Using alternative measures of crime and different micro geographies produces similar conclusions regarding strong crime concentration at place with narrow bandwidths. Our review shows that a general framework of a law of crime concentration applies across a large number of cities across many regions around the world.

For decades, scientists have explored the link between aggressive behaviors and being an athlete based on a persistent concern that behaviors encouraged during competition influence actions outside the sports context. Numerous publications have investigated the relationship between athlete identity and engaging in aggressive behaviors. Only a small percentage have used psychometrically validated instruments to measure aggressive behaviors. This is a critical limitation. The aim of this review is to summarize findings from studies preceding January 2023 that used validated measures to identify types and intensity of aggression. A total of 7392 articles were identified from several databases. Thirty-eight met the inclusion criteria. Fifteen compared athletes to non-athletes, and 23 examined aggression using athlete-only samples. Six comparison studies found no differences between athletes and non-athletes. Nine had mixed results. Among the studies that used athlete-only samples, competitive level, age, and sport type differentiated scores on the aggression measures. Methodological differences in the study designs (e.g., sample size, sport type, and competitive level) make it difficult to draw generalizable conclusions from this body of literature. Future research on this topic should focus on carefully constructing new studies or replicating existing ones paying close attention to the measurement instruments and study design methods.

Previous research has indicated a connection between physical activity and bullying behaviors among children and adolescents, however, there is a lack of in-depth exploration of this relationship. Therefore, we conducted a systematic review and meta-analysis to assess the relationship between the physical activity in children and adolescents and bullying behaviors. We searched the literature through the database until December 2023, and finally included 15 original studies through screening, and conducted a preliminary analysis, including both overall effects and detailed subgroup analyses. The results revealed a significant negative correlation between physical activity and bullying victimization (r = −0.16, p < 0.001) among children and adolescents, but no significant correlation with bullying (r = −0.01, p = 0.83). Our study extends current studies by examining various moderating factors, including the cultural and economic background and basic characteristics of the sample, different forms of bullying behaviors, different intensity and measurement forms of physical activity, which may influence the relationship between physical activity and bullying behaviors. The findings of this meta-analysis suggest a link between physical activity and bullying behaviors in children and adolescents, emphasizing the need to consider the influence of various variables in future intervention programs.

School bullying has been identified as a major issue among students throughout the world. With around 260 million school students, the largest student population in the world, it becomes essential to investigate this issue in the Indian context. The present work uses the Arksey and O'Malley (2005) framework for scoping review to examine the nature of research on school bullying in India and identify research gaps to be addressed by future research. The review maps the concepts examined, research approaches used, sample characteristics, data collection methods, researcher characteristics, and nature of publications in relation to bullying. Seven databases - JSTOR, PsycNET, Cochrane Reviews, ERIC, MEDLINE, Web of Science, and Cochrane Central Register for Controlled Trials - were searched for sources containing the terms “bullying” and “India” published in English and between the years 2015 and 2022. Thirty-eight sources selected for the review suggest that existing research in India on school bullying is limited compared to the West and yet provides a guiding light to future researchers. The findings from this review highlight research gaps in the existing literature and outline areas for further exploration.
