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.

Empowering Student Transition and Engaging Students Using Actionbound: A Gamified Collaborative Community Learning Platform

Transition to University is a significant milestone for students who are embracing new experiences and challenges. It is particularly vital for international students who have to adapt to a new and different learning environment in the UK. Successful transition and sense of belonging in a new institution lay foundation for students’ academic success. However, transition is a process rather than an event. Accordingly, fostering a collaborative community learning environment and facilitate peer networks and community support becomes critical. It enables social interactions and active learning by engaging students in collaborative group activities, which would in turn support students’ transition to and belonging in a new learning environment. With the advancement of technology, computer-assisted and computer-supported collaborative learning flourished in 21st century. The emergence of mobile digital technology leads to the design of gamification in learning, known as game-based learning or gamified collaborative community learning in order to engage students in fun and interactive activities. ‘Actionbound’ is one of the versatile gamification platforms and mobile apps which can engage students in collaborative community learning with gamified activities. It enables users to create, share and participate in interactive scavenger hunts, tours, games and quizzes. It allows users to design custom challenges, incorporate multimedia content and track players’ progress in real-time. It engages participants to work collaboratively to solve challenges and complete tasks. At UHBS, we have used Actionbound to support the student transition into the University’ learning journey at the start of term. We used scavenger hunt game and quiz functions within Actionbound to direct students to collaborate in teams to solve the challenges and tasks. In this action research, students found Actionbound fun and loved the competitive nature with points and leaderboards. It helped them build network and form friendship. Together, they solved puzzles and tackled challenges which supported their transition and got them prepared for learning in a new environment. Moving forward, as an ongoing action research, we would like to extend the use of Actionbound to term time and in module delivery so to track students’ engagement with the collaborative learning platform and investigate the impact on their academic performance.

Exploring the use of point-of-care ultrasound by pelvic health physiotherapists in the UK

National and international surveys have highlighted point-of-care ultrasound (PoCUS) as an emergent technology that is being utilized by physiotherapists across a variety of clinical specialities. It confers advantages beyond traditional physiotherapy assessment and increases treatment options for patients with pelvic health conditions. What is not known is how pelvic health physiotherapists are routinely using PoCUS, or the barriers and enablers to its use that exist specifically within this population. The aim of this service evaluation was to explore the current use of PoCUS by pelvic health physiotherapists who are part of the POGP professional network to identify barriers and enablers to wider use within clinical practice across the UK. An online survey with both multiple-choice and free-text responses was shared. Questions covered four domains of interest: (1) demographic and professional characteristics; (2) current use of PoCUS; (3) perceived barriers and enablers; and (4) training. One hundred and two pelvic health physiotherapists with varied levels of experience responded from different sectors and areas of the UK. Only 30.4% reported routine use of PoCUS in their clinical practice despite consensus that PoCUS is an important tool for the rehabilitation of pelvic health conditions. Most barriers to the use of PoCUS identified could be linked to resource limitations, training or lack of support, and were also reflected in suggestions for enablers. Most users had formal training and felt that this had been sufficient to be competent in using PoCUS in their service. Physiotherapists recognize the advantages that PoCUS offers for rehabilitation in pelvic health populations, but are often unable to access the equipment or training required. Ongoing support after training is needed to ensure that users maintain confidence and competence, especially as many work as independent practitioners and are without a direct peer network. Updates to national recommendations or guidelines to include PoCUS as a recommended tool within rehabilitation may provide the impetus needed to support its adoption across more public healthcare settings.

Engaging Communities in Energy Transitions: A Study on Attitudes Towards Sustainable Heating Technologies and the Role of Peer Effects in Southern Chile

This study investigates the role of peer effects in shaping the adoption of sustainable heating systems in two highly polluted communes in Southern Chile. Despite policies promoting cleaner alternatives, wood-burning stoves, a major source of particulate matter emissions, remain widespread. This research work addresses a critical gap in the literature by examining how peer influence—typically studied in relation to visible technologies like solar panels or electric vehicles—affects the adoption of less visible but essential sustainable heating technologies. The main objective of this study is to understand how peer networks can influence the attitudes of residents towards sustainable heating technologies in highly polluted urban environments. Employing a non-experimental, cross-sectional design with a sample of 244 participants, this study reveals that peer effects and health risk perception are significant predictors of positive attitudes towards sustainable heating systems. These findings contribute valuable insights for policymakers seeking to accelerate energy transitions in polluted regions.

Examination of Stress Among Recruit and Incumbent Women Firefighters

BackgroundFirefighting is risky and impacts the mental and physical health of personnel. While most research focuses on men firefighters, recent work has highlighted mental health concerns among women including depression, anxiety, and post-traumatic stress disorder (PTSD). Social support is a known protective factor for mental health; however, women may be excluded from the supportive peer network of the firehouse. MethodsThis cross-sectional study compared the prevalence of perceived stress, peer (functional) support, anxiety, depression, PTSD, chronic work discrimination and harassment, resilience, and job satisfaction in recruit (n=184) and incumbent (n=200) career women firefighters. ResultsWhile depression and perceived stress did not differ between recruits and incumbents, recruits were more likely to score in the range of concern for anxiety (26.1% and 15.5%, respectively). Incumbents were more likely to score at risk for PTSD (16.5% and 10.3%, respectively) and more likely to report sex discrimination, sexual harassment, and sexist behaviors in the workplace. Compared to the low stress group, those who reported moderate or high stress were more likely to score in the range of concern for anxiety (OR=3.86, CI=1.76-8.89) and PTSD (OR=1.30, CI=1.15-1.47), and report poor organizational cohesion (OR=1.13, CI=1.02-1.25). ConclusionAddressing mental health in the context of women firefighters requires a comprehensive and multi-faceted approach including collaboration between fire departments, mental health professionals, advocacy groups, and the broader community.

Proximity within adolescent peer networks predicts neural similarity during affective experience.

Individuals befriend others who are similar to them. One important source of similarity in relationships is similarity in felt emotion. In the present study, we used novel methods to assess whether greater similarity in the multivoxel brain representation of affective stimuli was associated with adolescents' proximity within real-world school-based social networks. We examined dyad-level neural similarity within a set of brain regions associated with the representation of affect including the ventromedial prefrontal cortex (vmPFC), amygdala, insula, and temporal pole. Greater proximity was associated with greater vmPFC neural similarity during pleasant and neutral experiences. Moreover, we used unsupervised clustering on social networks to identify groups of friends and observed that individuals from the same (versus different) friend groups were more likely to have greater vmPFC neural similarity during pleasant and negative experiences. These findings suggest that similarity in the multivoxel brain representation of affect may play an important role in adolescent friendships.

Farmland Degradation in the Czech Republic: Drivers and Barriers of Mitigation Strategies in Agricultural Soils

ABSTRACTIn line with Sustainable Development Goal (SDG) 15.3, which aims to restore degraded land and soil, and the priorities of the Common Agriculture Policy (CAP) to mitigate environmental issues caused by intensive agriculture, understanding the factors influencing farmers' adoption of soil conservation practices (SCPs) is crucial. However, there is still a limited understanding of these specific factors, particularly in the context of the Czech Republic. This study investigates the perceptions and determinants influencing the adoption of SCPs among farmers in the Czech Republic. We analyzed 358 randomly selected farm households using probit and multivariate probit models. Our results show that a significant number of farmers perceive soil degradation as an important problem, attributing it to factors such as low soil nutrient content, declining soil humus, water and wind erosion. The results of our analysis showed positive associations for perceived effectiveness and profitability, indicating that farmers tend to adopt practices such as minimum tillage, mulching, mixed cropping, cover cropping, and continuous soil cover when these methods are perceived to be effective and profitable. Conversely, negative associations are found for perceptions of soil degradation and education, suggesting potential barriers to adoption with higher levels of perceived soil degradation and education. The study also highlights the complex interplay of information sources on adoption, with both positive and negative trends. In light of these findings, we propose recommendations, including that awareness campaigns should be tailored to address perceptions of soil degradation, and that the use of peer networks and information dissemination from research institutions can bridge the gap between scientific recommendations and on‐farm practices. Policy makers and agricultural extension services should work together to develop targeted strategies that take into account regional differences in the factors influencing adoption and ultimately promote widespread adoption of SCPs.
