The rise of social media has offered adolescents opportunities for development and learning but has also introduced new challenges such as cyberhate. This study explores the dynamics of cyberhate among Ukrainian adolescents, focusing on exposure, victimization, and perpetration in the context of the ongoing war and displacement. Drawing on a sample of 4160 participants aged 10 to 25, we analyzed the relation between these roles using social learning theory as our conceptual framework. We also considered gender, age, and direct exposure to war activities in relation to cyberhate perpetration. Our findings indicate that males are significantly more likely to be perpetrators compared to females. Furthermore, victims of cyberhate and cyberbullying demonstrate a higher tendency to perpetrate cyberhate, suggesting a cyclical pattern of aggression. Individuals with cyberhate victims in their social circles, or those generally exposed to cyberhate, are more likely to become perpetrators as well. These insights contribute to the discourse on cyberhate prevention, emphasizing the need for targeted interventions.

The study explored the dual-path mechanism of human-computer parasocial relationships on consumer attitudes through an experimental approach. Innovatively, ‘assistant’ and ‘friend’ are proposed as the two basic parasocial relationships of human-computer interaction, with the two gender traits of artificial intelligence robots - "male trait" and "female trait" - to stimulate consumers' perceived competence and warmth through interaction, and improve consumer attitudes. Research has found that perceived competence and perceived warmth mediate the impact of two parasocial relationships, "assistant" and "friend", on consumer attitudes. Compared with the "friend" type of human-machine parasocial relationship, the "assistant" type of human-machine parasocial relationship significantly enhances consumers' perceived competence; Compared with the "assistant" type of human-machine parasocial relationship, the "friend" type of human-machine parasocial relationship significantly enhances consumers' perceived warmth. Meanwhile, research has demonstrated the moderate role of gender traits in artificial intelligence robots. This study broadens the research perspective of AI Services marketing, and provides important enlightenment for enterprises to develop Marketing strategy and AI Intelligent design.

Hashtags are integral to conversations and discussions on social media and are used to communicate emotions and meaning. However, little is known about how hashtags form impressions of social media users' personalities, credibility, and attractiveness. This study utilizes Social Information Processing Theory (SIPT) to examine if impressions can be formed about the sender based on their use of hashtags on social media. A between-subjects post-test-only experimental design was implemented in which participants (N = 322) viewed mock Instagram posts that differed in the number of hashtags utilized (low vs. high) and framing (positive, negative, neutral) and completed assessments on source perceptions of extraversion, neuroticism, narcissism, trustworthiness, and social attractiveness. Posts with a high number of positive hashtags were associated with higher perceptions of extraversion. Posts with positive hashtags made the source perceived as more socially attractive and trustworthy than those with neutral and negative hashtags. This research significantly advances theory by extending tenets of SIPT to understand how hashtags influence person perception on social media.

Due to environmental factors, work behaviors may suddenly change from human-machine collaboration to deviant behavior in intelligent environments, which can negatively impact human-machine efficiency. Thus, the factors that influence labor-intensive human-machine behaviors and their catastrophe and resilience mechanisms are explored in this paper. First, a conceptual model outlining the factors influencing human-machine behaviors is proposed in a qualitative analysis of city smart sanitation. Next, the threshold conditions for catastrophe in human-machine behaviors are analyzed using a stochastic catastrophe model. A resilience computational model is proposed, in which the resilience index accurately reflects the ability of human-machine behaviors to maintain stability in the face of random disturbances. Finally, numerical analysis reveals that digital supervision reduces the resilience of collaborative behavior and increases the resilience of deviant behavior and that humanitarian management mitigates both effects. The increase in humanitarian management decreases the catastrophe threshold of collaborative behavior but has no significant role in the catastrophe threshold of deviant behavior. From the perspective of behavioral resilience computation, this paper discusses two key arguments regarding the influences of humanitarian management and punishment on human-machine behaviors. This paper makes methodological and theoretical contributions to the understanding of human behavior in intelligent environments and provides theoretical insights for organizations managing employee behavior in digital transformation.

Although mobile dating applications (apps) are one of the most common ways for young adults in the United States to meet potential dating partners, online dating platforms have been inadequately examined in relation to young adults' offline sexual health practices. Grounded in objectification theory, this study explored how young adults' use of dating apps—and specifically whether their sexualized perceptions of and interactions with others—related to their ability to discuss sexual consent with sexual partners they met on those apps. We conducted an online survey of a national sample (N = 1045) of young adults in the U.S. on this topic. Results revealed that the more frequently participants used dating apps, the more they engaged in the sexual objectification of others on dating apps. Participants who were prone to sexually objectifying others on dating apps were also more likely to endorse ‘digital consent cues’ (the assumption that matching or exchanging DMs implies consent to sex) and reported greater difficulty discussing sexual consent with partners they met through such apps. The study yields insights into how dating apps and their technological affordances may alter or dimmish offline conversations about consent, making theoretical contributions and proposing solutions to foster the development of healthy and equitable sexual relationships.

Technostress refers to an individual’s inability to engage with emerging computer technologies in a constructive and healthy manner. Moreover, teaching is increasingly recognized as a stressful profession, with recent studies indicating a rise in technostress among educators. However, current research has failed to holistically map the sources, outcomes, and mitigation strategies for technostress among teachers. In this systematic review, we analyzed 54 studies sourced from Scopus, PubMed, and Web of Science to outline the landscape of technostress and identify key factors, including sources, outcomes, and strategies for mitigation. Our findings reveal a notable increase in research on teachers’ technostress since 2018, especially during the COVID-19 pandemic, with a predominant focus on studies from Asia and a significant absence of perspectives from North America. Common identified sources of technostress include technological factors, workplace conditions, and personal perceptions. Furthermore, the findings emphasize that technostress affects teachers’ well-being and overall job performance. Although research on the mitigation of technostress remains limited, several effective strategies have emerged at the personal (e.g., boosting resilience, promoting information technology mindfulness, and fostering meaningful work perceptions) and organizational (e.g., enhancing digital literacy, providing organizational flexibility, and offering technical support) levels. Finally, despite the current studies covering the sources and consequences of technostress, they provide an incomplete understanding of the formation of technostress. Overall, the gap in the literature highlights the urgent need to investigate the formation and mitigation of technostress among teachers at all levels. Our review provides up-to-date information for researchers, educators, and teachers about technostress and its mitigation.

Virtual worlds (VWs), an integral part of the metaverse, offer immense potential for virtual team collaboration. However, adoption challenges persist due to subpar user experience, highlighting the need to address the theoretical gap in understanding collaboration within VWs versus traditional virtual tools. This study applies Media Naturalness Theory (MNT) to compare cognitive effort, a vital user experience indicator, in VWs and instant messaging (IM). It also examines cognitive effort's impact on team performance, assessing two interventions: self-paced training and an icebreaker exercise. Data from three experiments reveal that VWs demand higher cognitive effort, resulting in diminished team performance. Self-paced training significantly narrows the cognitive effort gap between VW and IM users, while the icebreaker exercise reduces cognitive effort for both. These findings address the theoretical gap by suggesting that VW adoption hesitancy may stem from unfavorable comparisons with familiar alternatives and by emphasizing the importance of such comparisons to avoid misrepresenting VWs as inherently superior. This study also highlights the importance of media theories like MNT, which emphasize both media characteristics and user adaptation, for understanding collaboration challenges in VWs. It contributes to practice by identifying interventions to reduce the cognitive effort disparity between VWs and IM.

With the increasing popularity of smartphones in the past decades, physical, social, and psychological consequences of excessive smartphone use (ESU) have been increasingly debated. Cue-reactivity (CR) has been discussed as a core mechanism driving this behavior, and previous studies have highlighted distinct neural mechanisms underlying CR in individuals with ESU. Here, we used a functional MRI (fMRI) CR-paradigm to investigate the effects of smartphone restriction over 72 h in 25 young adult smartphone users. The CR-task used contrasts of images showing smartphones vs. neutral stimuli and active vs. inactive smartphones. Region-of-interest based correlations with psychometric scores were performed, and activity changes after 72 h were investigated on a neurochemical level using neurotransmitter probability maps. CR-related brain activity changes over time were most prominent in the nucleus accumbens and anterior cingulate cortex (p < 0.001). Such changes were significantly associated with dopamine- and serotonin-receptor probabilities (pFDR < 0.05). Significant associations between parietal cortex activity and craving were detected (p < 0.05). This study provides evidence for CR-related modulation of neural activity in key regions of salience, motor-inhibition, and reward processing after 72 h smartphone restriction. The identified neural mechanisms may substantially promote addictive behavior in people at risk for ESU.

Background and aims
The rapid development of digital technology has led to an increase in problematic online behaviors (POBs), including excessive smartphone use, gaming, and social networking site, particularly among adolescents. This study used data from Chinese adolescents to (1) examine the spectrum hypothesis, which posits that POBs are interrelated yet distinct, (2) test a previously proposed POB taxonomic framework by investigating the relationships between smartphone use and two other POBs, and (3) explore sex-specific differences in the symptom network.
Methods
We conducted a cross-sectional study of 7184 adolescents from two Chinese cities. Participants were assessed for problematic usage of smartphones (PUS), video gaming (PUVG), and social networking (PUSN) using validated psychometric tools. Network analysis was applied to evaluate symptom associations within and across POB types, and network community detection alongside confirmatory factor analysis was used to identify underlying structures. Network comparison testing was performed to examine sex differences.
Results
Stronger associations and communities were observed within specific POB types than between them, supporting the spectrum hypothesis. Core symptoms included PUS-escapism, PUSN-withdrawal, and PUVG-loss of control. Escapism and withdrawal also served as bridge symptoms. Network comparison revealed denser symptom networks among females, instead of males.
Conclusions
These findings underscore the importance of considering distinct POB types in adolescents. Future research and clinical strategies should prioritize content-based identification of POBs and devote greater attention to female adolescents. Collaboration among psychologists, clinicians, and policymakers is crucial to address the mental health challenges of the digital era.

Gaming disorder is a global issue that impacts adolescents’ social development. Aggression and hyperactivity/inattention symptoms have been suggested as core risk factors and adverse consequences for gaming disorder symptoms. However, longitudinal studies on the directionality of these relationships are scarce, and most do not distinguish within-person and between-person effects. To address this gap, a one-year longitudinal study was performed using data collected in three waves from 1296 Chinese adolescents (Mage = 13.73 ± 1.49, aged 11–17 years, 50.85% girls). We applied random intercept and traditional cross-lagged panel models to examine the within-person and between-person effects. At the within-person level, findings suggested a unidirectional relationship that gaming disorder symptoms increased the symptoms of hyperactivity/inattention and aggression, but not vice versa. The between-person results showed significant relationships between these variables, and that hyperactivity/inattention symptoms were a mediating mechanism for the longitudinal relationship between gaming disorder symptoms and aggression. These findings deepen the directional understanding of the relationships between them, and emphasize the critical role of gaming disorder symptoms in the development of hyperactivity/inattention symptoms and aggression among adolescents.
