Youth violence—the deliberate use of physical force or harm by young people between the ages of 10 and 24 to intimidate or cause harm to others, both online and offline—is a critical public health issue in the United States. Yet, successfully predicting future violent offenders is a complex and challenging task, as the question of why some youths resort to extreme violence while others refrain from it—despite facing similar risk factors—remains widely debated. This article highlights both risk and protective factors of youth violence through a socio-ecological lens to offer a comprehensive understanding of the multifaceted factors driving youth violence in the United States. To understand the interconnectedness between individual factors and the broader environments in which individuals are embedded, we outline the risk and protective factors related to youth violence across five socio-ecological levels: (1) individual, (2) interpersonal, (3) neighborhood, (4) cultural, and (5) life course. Approaching youth violence from a holistic lens offers a greater opportunity to mitigate contributing factors and to address the deleterious impacts of this complex issue. Practice and research implications are discussed. Full article

This study investigates the mechanisms underlying the diffusion of risk information about genetically modified organisms (GMOs) on the Chinese social media platform Weibo. Drawing upon social contagion theory, we examine how endogenous and exogenous mechanisms shape users’ information-sharing behaviors. An analysis of 388,722 reposts from 2444 original GMO risk-related texts enabled the construction of a comprehensive sharing network, with computational text-mining techniques employed to detect users’ attitudes toward GMOs. To bridge the gap between descriptive and inferential network analysis, we employ a Shannon entropy-based approach to quantify the uncertainty and concentration of attitudinal differences and similarities among sharing and non-sharing dyads, providing an information-theoretic foundation for understanding positional and differential homophily. The entropy-based analysis reveals that information-sharing ties are characterized by lower entropy in attitude differences, indicating greater attitudinal alignment among sharing users, especially among GMO opponents. Building on these findings, the Exponential Random Graph Model (ERGM) further demonstrates that both endogenous network mechanisms (reciprocity, preferential attachment, and triadic closure) and positional homophily influence GMO risk information sharing and dissemination. A key finding is the presence of a differential homophily effect, where GMO opponents exhibit stronger homophilic tendencies than non-opponents. Despite the prevalence of homophily, this paper uncovers substantial cross-attitude interactions, challenging simplistic notions of echo chambers in GMO risk communication. By integrating entropy and ERGM analyses, this study advances a more nuanced, information-theoretic understanding of how digital platforms mediate public perceptions and debates surrounding controversial socio-scientific issues, offering valuable implications for developing effective risk communication strategies in increasingly polarized online spaces.

From an outside perspective, it is not clear whether the Catholic Church is an active digital entity, or at least, it is not perceived as such. This paper analyses this issue. The methodology involved the monitoring of ecclesiastical Internet activity, SWOT analysis and in-depth interviews (seven) with clergy and technological suppliers of the Church in both Spain and Latin America. Results: Catholic Church digitalisation is spontaneous, as a reflection of society at large, and is heterogeneous due to its decentralised management. There is more inner acceptance of digital mediatisation for proclamation or support in faith (i.e., apps for praying) and less acceptance for the digitalised practice of rites (digital mediation in the celebration of sacraments is an open debate); however, the presence of ICTs in sacred places is increasing (i.e., liturgical books on screen). The evangelisation of the digital continent is an objective of the Church, whereby clergy influencers are the most striking but less solid case. There is almost full digital implementation at the functional level (i.e., digitised accounting and archives). Only charitable action with vulnerable groups remains analogue. Polarisation is also present, as ultra-Catholic groups are over-represented on the Internet. Conclusion: The Catholic Church is integrated in the Information and Digital Age but is also concerned with spiritual impoverishment, as online fragmentation does not feed real humanitarian communities.

This article carries out an interdisciplinary analysis of five MOOC courses developed by the University of Valladolid and offered on higher education platforms between 2020 and 2024. This research is based on the study of the lexical categories used by the informants participating in these courses, establishing a correlation with the theoretical and practical debates surrounding the definition of heritage and the frameworks of contemporary heritage education. Through a metalinguistic approach, the semantic limits of the emerging lexical categories are examined, paying attention to their ambiguity, polysemy and contexts of use, both from a formal linguistic perspective and from a hermeneutic approach. The analysis is based on natural language processing tools, complemented by qualitative techniques from applied linguistics and cultural studies. This dual approach, both scientific–statistical and humanistically nuanced, allows us to identify recurrent discursive patterns, as well as significant variations in the conceptualization of heritage according to the socio-cultural and geographical profiles of the participants. The results of the linguistic analysis are contrasted with the thematic lines investigated by our research group, focusing on cultural policy, legacy policies, narratives linked to the culture of depopulation, disputed scientific paradigms, and specific lexical categories in the Latin American context. In this sense, the article takes a critical look at discursive production in massive online learning environments, positioning language as a key indicator of the processes of cultural resignification and the construction of legacy knowledge in the Ibero-American context. The findings of my scientific article underscore the pressing need for a multiform liberation of the traditionally constrained concept of heritage, which has long been framed within rigid institutional, legal, and disciplinary boundaries. This normative framework, often centered on materiality, monumentalism, and expert-driven narratives, limits the full potential of heritage as a relational and socially embedded construct. My research reveals that diverse social agents—ranging from educators and local communities to cultural mediators and digital users—demand a more flexible, inclusive, and participatory understanding of heritage. This shift calls for redefining legacy not as a static legacy to be preserved but as a dynamic bond, deeply rooted in affective, symbolic, and intersubjective dimensions. The concept of “heritage as bond”, as developed in contemporary critical theory, provides a robust framework for this reconceptualization. Furthermore, the article highlights the need for a new vehiculation of access—one that expands heritage experience and appropriation beyond elite circles and institutionalized contexts into broader social ecosystems such as education, digital platforms, civil society, and everyday life. This approach promotes legacy democratization, fostering horizontal engagement and collective meaning-making. Ultimately, the findings advocate for a paradigm shift toward an open, polyphonic, and affective heritage model, capable of responding to contemporary socio-cultural complexities. Full article

As recent advancements in large language models enhance reasoning across various domains, educators are increasingly exploring their use in conversation-based tutoring systems. However, since LLMs are black-box models to users and lack human-like problem-solving strategies, users are hardly convinced by the answers provided by LLMs. This lack of trust can potentially undermine the effectiveness of learning in educational scenarios. To address these issues, we introduce a novel approach that integrates multi-agent debates into a lecture video Q&A system, aiming to assist computer science (CS) university students in self-learning by using LLMs to simulate debates between affirmative and negative debaters and a judge to reach a final answer and presenting the entire process to users for review. This approach is expected to lead to better learning outcomes and the improvement of students’ critical thinking. To validate the effectiveness of this approach, we carried out a user study through a prototype system and conducted preliminary experiments based on video lecture learning involving 90 CS students from three universities. The study compared different conditions and demonstrated that students who had access to a combination of video-based Q&A and multi-agent debates performed significantly better on quizzes compared to those who only had access to the video or video-based Q&A. These findings indicate that integrating multi-agent debates with lecture videos can substantially enhance the learning experience, which is also beneficial for the development of students’ high-order thinking abilities in the future.

The rise of information technology and artificial intelligence has sparked debates on data protection in various fields. Data protection has been addressed in court rulings long before Brazil’s General Data Protection Law (LGPD). This study analyzes jurisprudence related to data protection by examining 10,009 documents from the Brazilian States’ courts collected through a web scraping process in an online juridical platform without restricting the period of publication. This analysis reveals document distribution among state courts, with the southeast and southern regions being the most productive, and identifies key terms in each state court. This provides a deeper understanding of the legal processes surrounding data protection issues in each Brazilian region. Full article

#MeToo furthered the debates about sexual harassment in academia in different contexts and locations. In Portugal, two moments drove the media debates around sexual harassment in higher education. Specifically, the allegations that emerged at the Faculty of Law of the University of Lisbon (FDUL) in 2022, and the case related to the Centre for Social Studies (CES) of the University of Coimbra in 2023. This study aimed to investigate the media coverage of these cases and their respective contributions to the national debate on sexual harassment in academia. We analysed the opinion articles published online between April 2022 and June 2023 in five Portuguese newspapers, Diário de Notícias, Jornal de Notícias, Público, Expresso, Observador, and Correio da Manhã, conducting a comparative analysis of the two cases. Sexual harassment was broadly discussed as an endemic reality, exacerbated by the precariousness and gendered hierarchical structures of academia. At the same time, there was a tendency to personalize the debate, by focusing on Boaventura Sousa Santos, CES’s emeritus director. This served as a basis for the instrumentalization of sexual violence as a form of political attack against the left, thus weakening the potential of the debates about sexual and moral harassment in academia.

Background/Objectives: Glucagon-like peptide-1 receptor agonists are increasingly used worldwide for weight and hyperglycemia management. There is an ongoing debate on the presence of increased gastric residue, leading to complications such as aspiration and overall safety in patients receiving upper gastrointestinal endoscopy. We aimed to study the effect of GLP-RAs on endoscopy outcomes. Methods: We conducted a detailed search of online databases to select the studies which provided details of the effects of GLP-RAs on patients undergoing endoscopy. The outcomes of interest were odds of retained gastric content (RGC), aspiration risk, and aborted and repeated procedures. A random effect model was used to calculate the pooled odds of outcomes with a 95% CI. We further calculated the pooled odds of predictive factors associated with an increased rate of retained gastric residues in the study population. Results: We included 12 studies with a total of 105,515 patients, of which 32,144 were on GLP-1 RAs and 73,273 were in the control group. A total of 234 (0.73%) aspiration events in GLP-RA users were noted compared to 257 (0.35%) events in the control group. No increased odds (1.26, 95% CI 0.86–1.87, I² 34%) of aspiration were found in GLP-1 users compared to the non-GLP-1 group. Patients on GLP-1 RA had increased RGC compared to the control group (OR 6.30, 95% CI 5.30–7.49, I² 0%). The pooled odds of aborted (OR 5.50, 95% CI 3.25–9.32, I² 0%) and repeated procedures (OR 2.19, 95% CI 1.42–3.38, I² 0%) were significantly higher in GLP-1 RA users. Patients taking Tirazepatide had the highest percentage of RGC (18.9%), while exenatide users had the lowest rate (6.2%) of food retention. Patients undergoing concomitant colonoscopy were found to have significantly low pooled odds of RGC (OR 0.26, 95% CI 0.04–0.48). GLP-1 RAs use was independently associated with increased odds of RGC (3.91, 95% CI 3.21–4.62, I² 0%). The results were homogenous and stayed consistent in the sensitivity analysis. Conclusions: Although the odds of RGC and aborted procedures are high in the GLP-1 RAs group compared to the control, no significant difference in the odds of aspiration was found between the two groups. Simple measures such as a clear liquid diet for 24 h, as routinely set for patients undergoing colonoscopy, may reduce the risk of retaining gastric residue in these patient populations.

COVID-19 has reinvigorated the policy debate for a universal healthcare system, attracting much attention on social media. In this paper, we study the online discourse of Medicare-For-All before and after COVID-19 by examining the Twitter feeds of two opposing health advocacy groups—Physicians for a National Health Program (PNHP) and Partnership for America’s Healthcare Future (P4AHCF). Our empirical results show a sharp contrast between the two interest groups’ communication strategies. PNHP showed a consistent narrative before and after the onset of COVID-19 on 11 March 2020, marked by personalized stories, references to diverse demographic groups, and a growing number of Medicare-For-All tweets. In contrast, P4AHCF showed more scientific terminology and data-centric tweets and had an inconsistent narrative with a sudden surge in positive sentiments and a complete silence on Medicare-For-All right after 11 March. The difference in communication strategies is consequential. PNHP has higher engagement with Twitter users and is more adaptive to a pandemic narrative than P4AHCF. We discuss how distinctive social media strategies can be explained by the groups’ different audiences and resources. The findings add to our understanding of healthcare advocacy campaigns on social media and the implication of a pandemic for health policy reform. Full article

Climate change has become a prominent global issue, demanding the attention of governments and populations due to convincing scientific evidence concerning its sources and effects. Even though a strong commitment to finding ways of reducing individual emissions is an important element of coping with climate change, initiatives to enhance public awareness and engage people in climate-friendly activities seem to be overlooked. Individuals’ reactions to climate change are shaped by their understanding of its causes, consequences, and implications, and this is heavily influenced by communications on the topic in public media. However, the discourses offered on climate change are problematic, leading to oversimplification and differing levels of comprehension. The widespread contentious debate over the causes and implications of climate change, alongside a scarcity of published research on communication about climate change in developing countries, suggests significant information gaps must be addressed. An analysis was performed on 397 articles from Vietnamese online newspapers, employing content analysis and framing to examine the communication of climate change to the public in Vietnam in the past two decades. The findings indicate an anthropocentric framing of climate change, which highlights institutional solutions, set up at a psychological distance from the public. Moreover, the pervasive propaganda advocating for eco-friendly solutions and methods may generate an optimistic perception that this issue can be resolved without altering individual habits.

Although scientific literature already shows the connections between gamification, tourism and sustainability, there is still a gap in research into how gamification can transform cities into more playful, sustainable and intelligent tourism destinations. Gamification in tourism promotes engagement, education and innovation, enriching experiences and driving the development of smart destinations. This study advances this debate by employing a mixed methodology, combining a systematic review (supported by Rayyan, an artificial intelligence) and content analysis (supported by Iramuteq, a textual software, version 0.7 Alpha 2). Additionally, we used Dreamscape by Voyant Tools online for a geographical analysis of the textual corpus formed by n = 61 abstracts. The intersection of main findings from the techniques applied provides eight new insights on urban tourism education through gamification, which are as follows: (1) exchange between the Global North and South; (2) local and global participation; (3) collaborations to achieve the 17 SDGs; (4) improve urban destination marketing by ethics principles; (5) deepening disruption technology and ethics studies; (6) the transformation of reality by sciences; (7) gamification on interdisciplinary perspectives; and (8) the role of gamification on the tourism and hospitality industry. The results suggest that gamification in tourism can offer a new ontological approach to addressing sustainable urban development, highlighting both theoretical and practical challenges. This research has both theoretical and practical implications, advancing the concept of ecogaming by integrating technology, entertainment and sustainability, and reinforces its potential to educate and engage in sustainable urban tourism practices.

Background: Problematic social media (SM) use is a growing concern, particularly among adolescents who are drawn to these platforms for social interactions important to their age group. SM dependence is characterized by excessive, uncontrolled usage that impairs personal, social, and professional aspects. Despite the ongoing debate over recognizing SM addiction as a distinct diagnostic category, the impact of social feedback, particularly through the “like” button, on brain activity remains under scrutiny. Objective: This systematic review aims to study the neural correlates of online social feedback, focusing on the effects of the “like” feedback on brain activity using fMRI and EEG. Methods: The review followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA). Results: The review included 11 studies with 504 participants, identifying key brain structures such as the amygdala, ventromedial prefrontal cortex (vmPFC), and ventral striatum involved in reward processing. Positive feedback (“likes”) activates areas like the nucleus accumbens (NACC), vmPFC, and amygdala, with NACC correlating with increased SM use intensity. Negative feedback activates the ventrolateral prefrontal cortex (vlPFC) and left medial prefrontal cortex (mPFC). Behavioral data indicates that positive feedback influences subsequent social interactions. Conclusions: The review highlights disparities in the literature regarding the neural response to social feedback, emphasizing the need for further research to clarify the roles of sex, personality traits, and the person giving feedback. Overall, understanding the neurobiological underpinnings of SM engagement is essential for developing effective interventions to prevent or address the negative effects of excessive SM use.

This research work aimed to analyse the impact and potential of cardboard as a construction material, as well as cultural aspects and sustainable construction regulations, in the context of Lima, Peru. The study employed a mixed research methodological approach, including three case studies from Japan, the Netherlands, and the UK, online interviews, and surveys with British, Polish, and Peruvian architects. Additionally, a range of dynamic thermal simulations of an existing school building in the UK employing cardboard construction material were conducted to evaluate its impact on energy consumption. The survey revealed that there is a gap in information about the material applied to the architecture and construction environment, which is coupled with a general distrust and little credibility regarding its inclusion. However, cardboard is also seen as a complementary material in hybrid construction systems, with potential recycling enhancing environmental sustainability. The case studies showed cardboard structures can fulfil different functions with flexible designs that are adaptable to different contexts, simple, economical, accessible, recyclable, and capable of resisting natural disasters. However, post-construction consequences affect the structural integrity. Simulations carried out with EnergyPlus confirmed that cardboard has an optimal performance that can be a great complement or variation to traditional materials to reduce the carbon footprint and could meet the U-value requirements established in the construction regulations. Since it has low thermal conductivity and good acoustic insulation, it is recyclable and generates fewer CO₂ emissions, and it is economical, accessible, versatile, and light in use. For example, from a technical point of view, when used as thermal insulation, this element outperforms other conventional materials due to its cellular structure, which traps air, a poor conductor of heat. This study provides a set of guidelines for sustainable building practices. Such guidelines can be adopted to produce a prototype of a sustainable building using cardboard as the main construction material to contribute to the current debates on the state of building materials. It offers valuable perspectives on the development of building materials, construction techniques, and building regulations that can guide the way forward for sustainable building practices in the future, informing policymakers and building designers about construction techniques that adhere to building codes and lessen the built environment’s environmental impact.

In 2023, Brazil regained momentum in proposing innovative participatory institutions by launching a complex participatory experiment for budget planning within its “Multiannual Plan” (PPA). While this was not a scaled-up version of the local participatory budgeting plan that emerged decades earlier, its launch did reopen the debate on the possibilities of expanding political participation. The challenge was significant due to the intricate nature of budget planning and the complexity of the plan’s participatory design. This paper examines that experience by outlining the institutional design of the PPA Participativo and analyzing its results in terms of online participation. It also discusses the prominence of climate-related proposals, suggesting that the PPA Participativo serves as a relevant indicator of national concerns regarding climate-based issues. Building on previous experiences, the PPA Participativo is a strategy consisting of three layers: an online platform for digital participation, state-level meetings with civil society activists, and a high-level forum composed of members from national councils. This paper analyses some of the results from the online platform, which recorded 4 million visits from 1.5 million individual participants. These citizens were invited to submit proposals, vote for up to three proposals, and choose from a set of pre-designed government programs. The main concerns that emerged from this open-ended process included corporate demands, stemming from highly organized sectors, such as public health and education employees. However, animal rights also ranked among the most-voted proposals. The program of the Ministry of the Environment on climate change reached the top position in this segment, largely due to its strong campaigning strategy. This paper discusses these outcomes, drawing on evidence of both societal engagement and institutional activism to promote specific agendas. Full article

This paper contributes to international debates about ‘authenticity’ in higher education, especially where this is embroiled in technology-oriented aspects of educational policy and practice. It describes activity theoretical research in a setting of engineering higher education, in industrial attachments taking place at distance, during which students and lecturers experience problems with technology-mediated interactions. Prior to the research-intervention that we describe in the paper, these interactions had been implemented through top-down policy, with work-related practices being conducted in the name of authenticity—a notion used in framing education as preparing students for economic work, in which digital technologies are increasingly embroiled. We describe an activity theoretical approach, and an online Change Laboratory methodology, through which students and lecturers envision and enact change to these practices. Their activity is thus reconfigured through their confrontation and renegotiation of authenticity. Our core contribution is to illustrate, through exposing and aggravating contradictions in technology-mediated activity, how practice in higher education can be considered authentic in and of itself, as distinct from solely having authenticity in preparing students for economic work.
