Assessing the Victim-Perpetrator Overlap in Adolescent Dating Violence in China: A Latent Class Analysis.

There is a limited understanding of the pathways that lead to victim-perpetrator overlap in adolescent dating violence (ADV) particularly in developing countries such as China. Applying a latent class approach, the present study focuses on whether the overlap can be explained by theoretical constructs grounded in social learning, general strain, and social bonding theories, and whether these constructs relate to underexplored mediating mechanisms or are direct precursors. The study sample consisted of 1,787 dating adolescents (39.8% male; mean age = 17.82 ± 0.92 years) from a population of 5,820 adolescents in 32 high schools in Chinese cities and rural counties. We found a significant victim-perpetrator overlap in controlling, psychological, and physical ADV, with the proclivity increasing with the severity of ADV. Membership of groups engaged in general delinquency and those engaged in dating violence increased the odds of victim-perpetrator overlap. Peer bullying victimization was the most consistent direct predictor of victim-perpetrator overlap in family/peer/community settings; victimization resulting from interparental violence during childhood, peer bullying, and community violence was the most consistent indirect predictor. Neighborhood bonds had a greater impact than social bonds with family and school in terms of direct and indirect protective effects against victim-perpetrator overlap. Patterns of exposure to violent victimization in family/peer/community settings and patterns of social bonds cast new light on the nature of deviant peer (general delinquency vs. ADV) networks, which were found to operate as major mediating mechanisms in victim-perpetrator overlap.

Exploring Socio-Political Factors and Quality of Life Among LGBT Individuals in India

ABSTRACT The quality of life of queer individuals in India is a result of a complex sociopolitical climate which is what this study aims to explore through qualitative methodology. Previous research has explored the social factors that impact the wellbeing of LGBT individuals in western countries, while the impact of politics on the wellbeing of marginalized groups is still largely unexplored. Through thematic analysis, this study found that family support and peer networks are the two most important social structures that determine the quality of life of LGBT emerging adults in India, whereas the impact of politics on wellbeing depends on the level of political awareness of the participants and their socio-political privilege in terms of caste, class and gender. However, there were significant differences in the relevant factors that affect the quality of life for cisgender and transgender participants which leaves room for further research. The findings indicate intra-community conflicts and changing dynamics within the community, and there needs to be extensive research on understanding the intersectionality of different identities within the community and their impact on the lives of queer individuals.

Associations between violence in childhood, depression and suicide attempts in adolescence: evidence from a cohort study in Luwero district, Uganda

BackgroundMany studies have documented an association between violence victimisation and poor mental health. However, few studies use longitudinal data from low- and middle-income countries with attention to how associations differ by experiencing specific types of violence or alongside different contexts of peer and family support. In this study, we quantify the association between experiences of violence in early adolescence and depression and suicide attempts in late adolescence and explore whether this association is modified by family and peer connectedness.MethodsData came from the Contexts of Violence Against Children (CoVAC) cohort study in Luwero District, Uganda, involving 2773 participants aged 11–14 years at Wave 1 (2014) and 15–18 years at Wave 2 (2018). Physical, sexual, and emotional violence were measured at Wave 1. Mental health outcomes, depression symptoms in the past two weeks, and lifetime suicide attempts were measured at Wave (2) We used logistic regression models, stratified by sex, to estimate adjusted odds ratios with an interaction term to test for effect modification by peer and family connectedness at Wave 1.FindingsAt Wave 1, the prevalence of any violence from any perpetrator was 90% (physical violence: 87%, physical violence excluding caning: 68%, sexual violence: 6.3%, emotional violence: 56.8%). At Wave 2, 13.3% of participants had scores indicative of depression and 4.3% reported ever attempting suicide. Physical violence excluding caning, emotional violence, and sexual violence during early adolescence increased the odds of depression and attempting suicide in late adolescence for both boys and girls. Experiencing any violence (including caning) in early adolescence was not associated with depression in late adolescence, including in sex-stratified models. Childhood experience of any violence was associated with a suicide attempt violence in early adolescence (aOR: 2.60; 95%CI: 1.08, 6.27). High peer support mitigated the effect of any violence and physical violence on depression.ConclusionsFindings highlight the importance of efforts to prevent violence and improve access to response and support services for violence and mental health for young people. Findings also underscore the important role friends and peer networks can play in mitigating the effects of violence as young people grow up.

Exploring Media Literacy Formation at the Intersection of Family, School, and Peers

Today, media literacy and digital skills are essential for personal communication and social interaction. Children and adolescents need these skills to act autonomously in highly digitised social contexts. These skills are acquired in different social spaces, most frequently and primarily at home, followed by peer groups, school, and extracurricular activities. The present study aims to conceptually situate media literacy within a broader network of social power relations. It is therefore grounded in an academic theoretical framework that constructs media literacy as a form of digital cultural capital. As such, media literacy also contains the principles of media preferences and choices that condition the media choices of young people. This draws our attention to the social contexts in which media literacy and digital skills of children and teenagers are formed: within the family, school, and peers. With a selective thematic analysis of qualitative interviews with 67 primary and secondary school students (12–19 years), the empirical research is focused on different contextual incentives and regulations related to the formation of students’ media literacy, primarily in relation to digital media. First, we examine parenting practices that frame home access to media and media practices within families. Then, we explore the characteristics of formal media education within schools, which seems limited to teaching with/through media. Finally, we identify peer networks as important promoters of both digital capital and elements of advanced media practices and skills, compared to the media literacy encouraged within families and schools.

Navigating Barriers: Healthcare Anchor Institutions and Population Health Advancement

Background: Many United States hospitals explicitly pursue “anchor missions” by committing to intentionally apply place-based economic power and human capital in partnership with the community. Little is known about how hospital-community partnerships are implemented or whether they impact social determinants of health (SDOH) and population health. We qualitatively analyzed healthcare institutions from a national network to understand barriers and facilitators while implementing hospital-community partnerships that aim to improve population health. Methods: We used qualitative analysis of responses to open-ended items on a cross-sectional survey to explore how hospitals with anchor missions address SDOH. We administered the survey to healthcare systems participating in the Healthcare Anchor Network (HAN), a national network of hospitals with explicit goals to address SDOH and improve population health. Results: Responses were from 16 organizations. Two themes emerged: 1) healthcare systems faced many demands (i.e., COVID-19, financial stability), which competed with prioritization of the anchor mission, and 2) senior leadership engagement was critical for impact of the anchor mission and efforts to address SDOH and population health. Strategies to engage leadership included peer networking and providing repetitive education on community health inequities to hospital leaders. Conclusions: Although health systems show enthusiasm for population health, competing priorities often constrain anchor mission efforts to improve SDOH and population health outcomes. With external encouragement, such as changes to federal or state quality metrics reporting, payment incentives to address community health, or other policy changes, health systems will engage more with communities and be able to address SDOH.

Uptake of the hepatitis B vaccine among brothel-based female sex workers in Kampala, Uganda

BackgroundHepatitis B is a significant health problem worldwide, particularly among high-risk groups such as female sex workers (FSWs). In Uganda, it is highly recommended that FSWs receive the hepatitis B vaccine. However, there is limited evidence of the level of uptake of the hepatitis B vaccine and associated factors among FSWs in Uganda. This study aimed to assess hepatitis B vaccine uptake and associated factors among FSWs in Kampala district, Uganda.MethodsWe conducted a cross-sectional study using data from 400 FSWs in Kampala, Uganda. We utilized a researcher-developed digitized semi-structured questionnaire and employed multistage sampling to enroll participants. Data analysis was performed using STATA version 14.0. Continuous data were expressed as mean and standard deviation whereas categorical data were reported as frequencies and proportions. We employed Modified Poisson regression analysis to assess the relationship between predictor variables and the uptake of the hepatitis B vaccine.ResultsA total of 400 respondents (98.5% response rate) were surveyed. Close to half, 49.8% of the respondents had ever heard about hepatitis B, and only 16.5% had received at least a hepatitis B vaccine dose. Individual factors significantly associated with hepatitis B vaccine uptake included spending more than four years in sex work (APR: 1.06, 95% CI: 1.01–1.12), previous screening for hepatitis B (APR: 1.49, 95% CI: 1.38–1.61), and having work conditions that allowed time to seek HBV services (APR: 1.13, 95% CI: 1.04–1.22). Health system factors significantly associated with vaccine uptake included the presence of hepatitis B outreach programs in residential areas (APR: 1.17, 95% CI: 1.03–1.33) and receiving information about hepatitis B from peers (APR: 1.07, 95% CI: 1.05–1.31).ConclusionThe study revealed a low prevalence of hepatitis B vaccine uptake among FSWs, with less than a tenth completing the three-dose schedule. Therefore, enhancing screening programs, expanding outreach initiatives, and tailoring services to accommodate nontraditional work hours while leveraging peer networks can significantly improve vaccine uptake and reduce hepatitis B transmission in this high-risk population.

The Impact of Social Media on Mental Health: A Comprehensive Review

Introduction: This comprehensive review explores the multifaceted relationship between social media use and mental health, highlighting its positive and negative effects. While social media fosters connectivity and mental health awareness, excessive use has been linked to adverse outcomes such as anxiety, depression, and cyberbullying. It is utilizing theoretical frameworks such as Social Comparison Theory and the personal Model.Objectives: This study examines how curated online interactions influence psychological well-being. Methods: A systematic scoping review was conducted, encompassing recent studies from 2019 onward. Results: Findings reveal that age, developmental stage, and usage patterns significantly moderate the effects of social media on mental health. Emerging concerns include Fear of Missing Out (FOMO), sleep disturbances, and low self-esteem, particularly among adolescents and young adults. Despite its challenges, social media presents opportunities for mental health support through peer networks and online interventions. Conclusions: This review underscores the need for tailored strategies, digital literacy programs, and policy regulations to mitigate risks and maximize social media’s potential for positive mental health outcomes. Future research should focus on longitudinal studies, cross-cultural analyses, and innovative digital interventions to address gaps in understanding the complexities of social media's impact on mental health.

Key Mental Health Challenges: The Role of Health Policy After COVID-19

Background; The COVID-19 pandemic profoundly impacted global mental health, revealing vulnerabilities in healthcare systems and exacerbating issues such as anxiety, depression, and PTSD. Vulnerable groups, including healthcare workers, young adults, and children, faced heightened risks due to social isolation, economic uncertainty, and disruptions to daily life. These challenges emphasized the critical need for targeted interventions and systemic improvements in mental health care. Objective; This review aims to analyze the key mental health challenges emerging post-pandemic, evaluate the roles of government policies and community interventions, and propose evidence-based strategies for prevention and rehabilitation. Additionally, it highlights innovative solutions to address service gaps and promote resilience. Methodology; A narrative review methodology was employed, synthesizing data from peer-reviewed journals, organizational reports (e.g., WHO, OECD, UNICEF), and national datasets from 2019–2023. Key themes—mental health challenges, government roles, prevention strategies, and innovative interventions—were explored through qualitative and quantitative analyses. Selection criteria focused on mental health conditions exacerbated by the pandemic and policy responses at local and national levels. Conclusions; The pandemic underscored the importance of mental health as a public health priority. Effective interventions include integrating mental health into broader health policies, increasing funding, and promoting public awareness. Prevention strategies focusing on early detection, lifestyle interventions, and community support proved vital, while rehabilitation efforts such as family involvement, peer networks, and technological tools facilitated recovery. A multisectoral, evidence-based approach is essential to build resilient mental health systems capable of addressing future challenges.

The impact of social media exposure and online peer networks on green purchase behavior

Green purchase behavior has grown significantly to promote sustainable living and minimize the environmental impacts of increasing consumption. There are limited research investigating the impact of green digital interaction influence customers’ pro-environmental practices. Drawing from customer value theory, the objective of the present study is to investigate the mediating role of perceived values in the relationship between green digital interaction and green purchase intention. A total of 308 participants were recruited to complete a survey regarding green purchases in China. Structural equation modelling (SEM) was used, and the findings provided empirical evidence that emotional value is a central concept that mediates the relationship between green digital interaction and other value dimensions. The study provides significant findings for organizations and marketers to implement more effective digital marketing strategies to promote green products.

Intimate Partner Violence among Adolescents in Hong Kong.

Intimate Partner Violence (IPV) among adolescents is a prime public health concern worldwide. Research found that IPV victimization and peers' IPV perpetration could increase the likelihood of IPV perpetration. In contrast, healthy partner attachment, forgiveness, shame management, and family harmony could serve as protective factors for IPV. Therefore, this study aims to investigate the risk and protective factors of IPV perpetration among adolescents in Hong Kong. The present study recruited 1,815 full-time secondary school students in Hong Kong aged 11 to 19 years. Healthy partner attachment, forgiveness, shame management, and family harmony were negatively correlated with IPV perpetration. IPV victimization and peers' IPV perpetration were positively correlated with IPV perpetration. Specifically, peers' IPV perpetration partially mediated the effect of IPV victimization on IPV perpetration. Thus, the effectiveness of intervention programs targeting IPV could be enhanced by resolving the traumatic experience of IPV victimization and promoting positive peer networks and support.

Exploring leaving-care and post-care experiences: What have helped care leavers in China?

The transition out of state out-of-home care is a critical and challenging phase for young individuals with care experience worldwide, yet there is limited understanding of the positive aspects of this transition, particularly in China. This study employs a qualitative research approach to explore the protective factors that facilitate young people’s transition out of care and their adaptation to post-care life. Thematic analysis of semi-structured interview transcripts from 22 care leavers in China highlights the significant role of personal qualities and support from significant others in navigating the challenges at each life stage. Supportive relationships are crucial, providing continuous influence throughout their life journeys. Additionally, the development and strengthening of family and peer networks further enhance young people’s resilience and life satisfaction in the post-care period. However, the study also identifies substantial gaps in formal support structures, underscoring the need for policy and practice innovations to better address the unique needs of care leavers. This research contributes to the understanding of care leavers’ experiences in China and offers insights that may inform the development of more effective support mechanisms to improve their outcomes in adulthood.

A secured channel for transmitting multimedia contents in peer-assisted networks

The Internet's explosive growth has raised demand for effective online video streaming services and cast doubt on the viability of peer-to-peer (P2P) networks and conventional content distribution networks (CDN). To facilitate efficient video streaming, Peer-Assisted Networks (PA-CDNs) integrate the best aspects of P2P networks and CDNs. Transferring data content across a protected channel platform is crucial since the PA-CDNs strategy uses both servers and peers, optimizing both delivery methods to offer the best possible user experience. However, it is vulnerable to assaults. By guaranteeing secure access management and addressing security concerns, this study offers a strong security model to strengthen and improve security in PA-CDN network environments. The outcome of the experiment indicates that the strategy works. Strong security model to strengthen and improve security in PA-CDN network environments. The outcome of the experiment indicates that the strategy works.

Unmet Needs of Children and Young Adults With ADHD: Insights From Key Stakeholders on Priorities for Stigma Reduction.

Individuals with ADHD continue to face stigma, which can negatively impact their access to, adherence to, and quality of mental health services, as well as their overall wellbeing. Perspectives of various stakeholders regarding priorities for stigma reduction remain underexplored. This study explores young adult, parent, teacher, and mental health care professional perspectives on unmet needs of children and young adults with ADHD in the Netherlands, in the context of stigma reduction. A total of 24 respondents participated in seven small focus group discussions (FGDs). The FGDs facilitated in-depth discussions exploring stakeholder group perspectives on unmet needs of children and young adults with ADHD in educational, professional, and social settings. Data was analyzed using thematic content analysis. Three thematic categories of unmet needs were identified: (1) a lack of awareness, knowledge, and understanding of ADHD; (2) insufficient personalized approaches in education and health care; and (3) limited accessibility of information and support services. Within theme 1, respondents primarily highlighted the importance of improving education for primary school teachers and mental health care professionals. Theme 2 underscored the need for increased capacity for personalization and attention to the sociopsychological factors of ADHD, alongside recognizing strengths. Theme 3 emphasized the need for easy access to reliable information and mental health care, including peer networks, as well as proper follow-up and continuity of care. Findings highlight the need for improving our understanding of ADHD as a complex biopsychosocial condition, which requires specific adjustments in education and mental health care. Interventions to improve support and disrupt stigmatization should meet diverse needs, incorporate multi-level strategies, and involve key stakeholders.

Navigating the First Years: Newly Qualified Teachers’ Experiences with Professional Learning Communities

AbstractDrawing on a mixed-methods evaluation of the New Teacher Induction Programme of the South African Department of Basic Education, this paper examines the role of Professional Learning Communities in enabling the transition of newly qualified teachers (NQTs) into their professional roles in schools. The article focuses on one of the four components of the induction programme, namely, the participation of NQTs in Professional Learning Communities (PLCs) and examines the experiences of newly qualified teachers as members of their respective professional learning communities. It begins by examining the range of typical early career challenges and, thereafter, shows how the social capital fostered through their collaboration in communities enables to overcome a range of challenges they face. As the results of the study show, PLCs provide safe spaces where new teachers experiment, share experiences and engage in collective reflection and problem-solving. The new teachers reported a range of professional and personal benefits, including their professional growth, expanded peer networks, and a stronger sense of belonging. Moreover, their responses show how their participation in PLCs contributes to developing their self- and collective efficacy, increasing their resilience, and enabling their transition into the teaching profession. As a participatory action research study, the paper shows the dual benefits of the PLCs – both in supporting the personal and professional development of novice teachers and in informing the development of broader educational policy. The results of the study led to the expansion of the New Teacher Induction Programme and the national adoption of PLCs – illustrating how teacher experiences can inform policy in bringing about meaningful change.

Adoption and User Behaviour Towards Digital Payments by Millennial

The rapid adoption of digital payment systems has transformed the financial landscape, particularly among millennials, who are at the forefront of this technological shift. This study explores the adoption and user behaviour of digital payment methods among millennials in India. The research aims to identify the key factors influencing the decision to use digital payments, including convenience, security, trust, and government initiatives. Additionally, it examines how socio-cultural influences, mobile payment applications, and peer networks impact the payment choices of this demographic. Through a survey of 250 millennials, the study reveals that ease of use, trust in security features, and promotional incentives are the primary drivers of digital payment adoption. It also identifies challenges such as concerns over data privacy and digital literacy. The findings suggest that while millennials are increasingly adopting digital payment systems, their behaviour is shaped by a complex interplay of technological, economic, and social factors. The study provides insights into strategies for improving the digital payment ecosystem and encourages further research into the evolving behaviour of young consumers.

How do personality traits affect the formation of friendship and preference-for-collaboration networks?

Intuitively, personality traits may shape friendships differently from academic connections, potentially influencing social support development. Yet, this remains understudied, while it is crucial for student’s wellbeing. Therefore, this study investigates how the personality traits of the Five-Factor Model interact with the role friendships and preferred collaboration relationships. In a sample of 95 university students, socio-centric data were collected with questionnaires on personality traits and longitudinally on networks of friendship and preferences for collaboration networks. Utilizing stochastic actor-oriented models in RSiena, we showed that students more open to new experiences established more friendships, preferred more collaborations with their peers, and were also more popular in both networks than students less open-to-new-experiences. Students scoring higher on agreeableness were less likely to connect to their peers in both networks, whereas higher-achieving students were more likely to establish peer relationships in both networks. Furthermore, friends were preferred for collaboration (and vice versa), indicating an overlap. This study points to the importance of personality traits and achievement when students integrate into their social and academic environment.

Childhood maltreatment associated with adolescent peer networks: Withdrawal, avoidance, and fragmentation

BackgroundChildhood maltreatment can affect subsequent social relationships, including different facets of peer relationships. Yet, how prior maltreatment shapes adolescents' connections within school peer networks is unclear, despite the rich literature showing the importance of this structural aspect of social integration in adolescence. ObjectivesThis study examines how childhood physical abuse, emotional abuse, sexual abuse, and physical neglect predict adolescent social network structure as withdrawal, avoidance, and fragmentation among peers. Participants and settingData from the National Longitudinal Study of Adolescent to Adult Health (Add Health) Waves I, III, and IV yield a sample of 9154 respondents with valid network data and survey of childhood maltreatment. MethodsModels using linear regression examine childhood maltreatment predicting withdrawal, avoidance, and fragmentation in adolescent peer networks. Maltreatment is first measured as ever occurring, then separately by maltreatment type. ResultsResults indicate that experiencing any maltreatment leads to withdrawal (lower sociality, B = −0.214, p = 0.008), avoidance (lower popularity, B = −0.222, p = 0.007), and fragmentation (lower cohesion, B = −0.009, p < 0.001). However, different types of maltreatment are associated with different dimensions of peer networks, with only physical neglect impacting all three dimensions. ConclusionsExperiencing any maltreatment in childhood predicts lower integration in the adolescent peer network structure across three dimensions. However, distinct types of maltreatment relate differently to separate network dimensions, with sexual abuse predicting withdrawal, emotional and physical abuse predicting avoidance and fragmentation, and physical neglect predicting lower integration on all three dimensions.

The Frequency and Characteristics of Brokered Illegal Drug Sales: Reconceptualizing Illegal Drug Markets and Measuring Local Demand

Background Drug policies and interventions require an ongoing understanding of the local demand for illegal drugs. How illegal drugs are distributed to consumers is critical in the demand process. To overcome barriers to purchasing illegal drugs, people utilize their peers to purchase substances for them. These brokered drug sales allow buyers to leverage their peer networks to make purchases. For brokers, this form of exchange allows them to obtain drugs for free. This drug acquisition strategy is underappreciated in understanding how local drug market's function. Methods This paper presents findings from a brief survey on brokering collected from a random sample (N = 241) of active illegal drug injectors recruited from two syringe services programs in Ohio, USA. Results Findings indicate that 30-day and lifetime brokering behavior is common (71% and 90% respectively). Respondents who brokered in the last 30 days (n = 181) purchased drugs for an average of 7 people and from an average of 4 different sellers. Among this group, over 84% indicated that they used drugs with the person they brokered for, 49% reported often or always inflating the price to the buyer, and 27% indicated they removed some drug before returning to the buyer. Conclusion Measuring brokering offers new insight on the dynamics of drug markets, how they operate, and ways to measure their activity. The demand for illegal drugs incorporates the increased use of a drug, changes in the use of different drugs, and/or a novel drug being used. Accessing drugs via brokering accommodates these dynamics. By including brokering in drug market activity, the concept and scope of illegal drug markets transform into networks and not places.

A four-factor model of executive function: Predicting physical and academic outcomes from cognitive assessments in adolescents

Impulsivity and cognitive function are essential for understanding behavioral regulation, particularly in relation to health-risk behaviors like substance use, physical activity, and academic performance. This study examined the factor structure underlying executive function in adolescents using the UPPS-P Impulsive Behavior Scale and NIH Toolbox Cognition Battery. We explored how parental monitoring moderates, and peer network health and perceived stress mediate, relationships between cognitive function and outcomes such as BMI, physical activity, and academic performance. Exploratory factor analysis (EFA) on 2228 observations identified a four-factor model (BIC = −97.92, RMSEA = 0.040, TLI = 0.936), validated by confirmatory factor analysis (CFA) (CFI = 0.961, RMSEA = 0.055). Structural equation modeling (SEM) on 5902 observations showed that parental monitoring moderated Factor 1 (adaptive impulsivity) in relation to physical activity and academic performance, while peer network health mediated Factor 2 (emotional impulsivity) effects on BMI and physical activity. This model underscores the influence of peer relationships, parental involvement, and stress on cognitive, health, and academic outcomes, suggesting that interventions enhancing peer support, reducing stress, and promoting healthy behaviors may improve adolescent well-being.

Cryptocurrency and Money Laundering

Cryptocurrency, a form of virtual currency, is increasingly pervasive in the modern society. People can use Bitcoin, Ether or Dogecoin to buy a range of products and services with ease and convenience. Yet, beneath the popularity of cryptocurrency is an emerging socio-legal concern: money laundering. Using the information collected from web sources, this brief paper taps into how cryptocurrency money laundering works and what measures can be undertaken to curtail digital crime. In view of the extant information, the paper found that a mixer is required as a ‘middle man’ to convert identifiable crypto-tokens into unidentifiable clean ones thereby delivering them to new wallet(s). In this manner, the origins of these tokens can be obscured, and the new tokens can be accessed and used legally. Many platforms and channels can serve as the mixer to proceed with illegal activities, including casinos, dark web marketplaces, and p2p networks. In considering the ways to tackle such digital crime in jurisdictions with limited oversight, the paper proposes to adopt measures in the Anti-Money Laundering initiatives already implemented in Hong Kong, the United States, and Singapore – especially, the need to strengthen recordkeeping to enhance the traceability and trackability of cryptocurrencies. Meanwhile, laws and rules associated with digital crime shall also be reshaped for risk mitigation.
