The rapid expansion of digital technologies has created an unprecedented level of increased connectivity, yet the neurobiological mechanisms underlying these changes remain incompletely understood. This systematic review synthesizes the currently available evidence on neurobiological findings related to problematic internet use, problematic smartphone/social media use, and internet gaming disorder, with a focus on reward processing, attentional control, and emotional regulation. Across the included studies, recurrent findings suggested the involvement of fronto-striatal circuitry, salience- and reward-related regions, and executive-control networks. Alterations in large-scale brain networks, including the default mode, salience, and frontoparietal systems, were also reported, although the evidence base was heterogeneous and consisted largely of cross-sectional studies with modest sample sizes. Overall, the findings support a provisional neurobiological framework linking reward-related processing, inhibitory-control difficulties, and large-scale network alterations, but better-standardized studies are needed to draw conclusions.

This article examines how the Ecuadorian national digital press has represented the relationship between criminal violence, declining mobility, tourism contraction, and the erosion of intangible cultural access in Machala, Puerto Bolívar, and the route to Jambelí during 2025. This study aims to explain how mediated representations of insecurity can contribute to the symbolic narrowing of culturally meaningful urban–coastal spaces, even when those spaces remain materially present and formally open. The article responds to a gap in the literature at the intersection of critical heritage studies, media framing, urban fear, and Latin American security studies. The existing research has examined heritage as social practice, media representation of crime, and urban securitization, but has rarely connected these fields to explain how criminal violence erodes lived access to intangible cultural environments in secondary port cities of the Global South. Methodologically, this study applies qualitative content analysis to a purposive corpus of eight focal journalistic texts published in Ecuadorian digital outlets, such as El Universo, El Comercio, Expreso, El Mercurio, Extra, Primicias, GK, and La Hora. Deductive–inductive coding was complemented by descriptive article-level indicators of themes, keyword clusters, and temporal distribution. The findings show that the press did not merely report violent events; it progressively reorganized the symbolic meaning of Machala by re-signifying Puerto Bolívar, the marine environment, the cabotage pier, and the maritime route to Jambelí as spaces of risk, interruption, and conditional access. This study contributes conceptually by defining intangible cultural access and symbolic enclosure, empirically by documenting the mediated erosion of coastal public–cultural life, and practically by proposing integrated policy actions for security governance, cultural reactivation, local commerce, maritime mobility, and responsible public communication.

Faced with the challenges of cross-cultural communication of public opinion in emergency events, traditional sentiment recognition methods struggle to accurately capture the complex semantics under multi-lingual and multi-symbol systems. This paper takes the powerful 7.7-magnitude earthquake that struck Myanmar in 2025 as a case study. It constructs a multi-dimensional public opinion annotation framework that integrates four types of semantic information—time, space, subject, and sentiment—by extracting data from multi-source textual materials, including social media, news reports, and government announcements. Building on this foundation, we design an improved Model-Agnostic Meta-Learning (MAML) model that incorporates cultural features to enhance sentiment recognition performance in low-resource cross-linguistic scenarios. Experimental results show that the model outperforms traditional methods in terms of sentiment classification accuracy, cultural semantic deviation rate and metaphor recognition ability. Furthermore, the research reveals the coupling mechanism of public opinion communication of “cultural modulation–agenda game”, and clarifies the influence paths and weight distributions among multiple subjects. The research results provide theoretical support and practical paths for improving the governance capacity of cross-border public opinion in emergency events and the construction of multilingual monitoring models.

Background: Anorexia nervosa (AN) commonly emerges during adolescence and disproportionately affects girls. In recent years, problematic social media use (PSMU) has been identified as a potential sociocultural risk factor for eating disorder symptoms; however, the psychosocial pathways linking PSMU to AN symptomatology remain insufficiently understood. This study examined the associations between PSMU and AN symptoms in adolescent girls and explored the roles of perceived parenting style and childhood traumatic experiences as explanatory pathways. Methods: A cross-sectional, school-based survey was conducted with 463 adolescent girls aged 13–18 years in İstanbul, Türkiye. Participants completed validated self-report measures assessing AN symptoms (Eating Attitudes Test–26), problematic social media use (Social Media Disorder Scale), perceived parenting style (Parenting Styles and Dimensions Questionnaire), and childhood trauma (Childhood Trauma Questionnaire). Structural equation modeling was used to examine direct and indirect associations between PSMU and AN symptoms, controlling for age, body mass index, and socioeconomic indicators. Indirect effects were tested using bias-corrected bootstrapping. Results: Problematic social media use was directly associated with greater AN symptom severity (β = 0.18, p < 0.001). Significant indirect associations were also observed via perceived parenting style (β = 0.06, 95% CI [0.03, 0.11]) and childhood traumatic experiences (β = 0.07, 95% CI [0.04, 0.12]). Childhood trauma accounted for a larger proportion of the indirect association, while parenting style contributed a smaller but significant pathway. When both pathways were included simultaneously, the direct association between PSMU and AN symptoms remained significant, indicating partial mediation. Model fit indices indicated good overall fit. Conclusions: Problematic social media use is meaningfully associated with anorexia nervosa symptoms among adolescent girls, both directly and through indirect pathways involving parenting context and childhood trauma. Childhood trauma may be interpreted as a variable showing a significant indirect statistical association with both problematic social media use and anorexia nervosa symptoms, rather than a causal determinant within the present design. These findings underscore the importance of integrated, trauma-informed and family-sensitive prevention strategies that address adolescents’ digital environments alongside broader psychosocial vulnerabilities.

With the intensification of global climate change and rapid urbanization, urban flooding poses an increasing threat to urban safety and sustainable development. Flood susceptibility mapping (FSM) serves as a practical approach for recognizing areas that may be vulnerable to flooding and is therefore essential for flood mitigation and urban planning. In this study, an interpretable ensemble machine-learning framework for urban FSM was developed using social media data. First, the spatial locations of flood events were extracted from social media posts and news reports to construct a flood inventory. Subsequently, a non-flood sample selection strategy, termed Similarity- and Diversity-Based Representative Sampling (SDRS), was proposed to ensure both sample similarity and diversity. Based on these samples, a heterogeneous bagging-based ensemble machine learning model was established for flood susceptibility assessment. To enhance model interpretability, the GeoShapley method was introduced to quantify the contributions of key conditioning factors and reveal their directional effects. The findings indicated that the proposed SDRS strategy delivered the best performance, yielding an AUC of 0.893 and a test-set precision of 0.859. The resulting susceptibility map exhibited a clear south-to-north decreasing gradient, with High- and Very-high-susceptibility zones accounting for approximately 26% of the study area (1897.23 km²). The interpretability analysis further indicated that the Nighttime Light Index (NLI), Impervious Surface Percentage (ISP), and population density were among the most strongly associated positive factors in the model, with a Global Spatial Share of 7.18%. These findings demonstrate that the proposed framework can reliably recognize areas vulnerable to flooding and offer a scientific basis for urban flood management in Guangzhou. Full article

The increasing use of digital technologies (DT) among university students has raised concerns about their associations with mental health (MH) and academic performance. Grounded in the Diversity in Learning (DinL) framework, this cross-sectional study examines how age and sex moderate the relationships between DT use, MH indicators, learning-related psychological difficulties, and academic outcomes. Data were collected through an online questionnaire administered to 4519 university students in Chile. The survey included self-reported measures of MH indicators and learning-related psychological difficulties (bad mood/irritability, anxiety, lack of motivation, attentional difficulties, and low achievement expectations), as well as academic performance and frequency of use of digital tools (social media, smartphones, gamification and collaboration applications, and asynchronous classes). Descriptive analyses, ANOVAs, and multiple regression models were employed. Results showed that younger students reported more frequent use of gamification apps, social media, and smartphones, as well as higher levels across all mental health issues and learning-related psychological difficulties. Social media use and particularly smartphone use emerged among the DT variables as the strongest predictors of MH problems and learning difficulties, with age significantly moderating these relationships. These predictors were significant for both young female and male students, although stronger associations were observed among females. Female students reported higher levels of MH problems (especially anxiety), as well as greater use of social media and smartphones. However, neither social media use nor smartphone use showed a consistent negative relationship with academic performance. Overall, these findings highlight the importance of considering age and sex differences when examining the links between digital engagement and student well-being. They also underscore the need for targeted interventions to promote healthier digital habits and emotional regulation strategies, particularly among higher-risk groups. Full article

Background: Eating disorders are on the rise among emerging and young adults, driven by familial dynamics, social media, psychological traits, and cultural, genetic, and peer factors. Yet not all underlying variables are fully understood. This study explores relationships between the differentiation of self (a crucial family pattern), problematic social media use, internalization of appearance ideals, negative body image, and the risk of eating disorders, aiming also to identify risk profiles. An additional objective was to examine differences between emerging adults and young adults, two age groups that have recently experienced increased prevalence of eating disorders. Methods: Participants included 333 emerging (n = 114, 34.2%) and young (n = 219, 65.8%) adults aged 18–40 (mean age 29.53; 207 females, 126 males) who completed questionnaires assessing the study variables. Results: The results revealed a sequential mediation effect: differentiation of self contributed to risk of eating disorders via problematic social media use, internalization of appearance ideals, and negative body image. Emerging adults (18–25) reported a higher risk of eating disorders, problematic social media use, internalization of appearance ideals, and emotional reactivity/fusion with others than young adults (26–40). A risk profile emerged: young, single, child-free women with a lower education and socioeconomic status, lower differentiation of self, and higher internalization of appearance ideals and problematic social media use. Conclusions: These findings highlight the importance of addressing both familial and societal factors—particularly differentiation of self, problematic social media use, and internalization of appearance ideals—in prevention and intervention programs for eating disorders. Developing tailored strategies for high-risk groups, such as young, single women with lower education and socioeconomic status, may enhance program effectiveness. Full article

Background/Objectives: Metabolic and bariatric surgery (MBS) is increasingly performed worldwide and requires specific anesthetic management due to the complex physiological alterations associated with severe obesity. Although several international guidelines provide recommendations for perioperative care in bariatric patients, their implementation in routine clinical practice may vary. This study aimed to report anesthetic practices among Polish anesthesiologists providing anesthesia for bariatric procedures. Methods: A cross-sectional survey study was conducted in October 2025 among Polish anesthesiologists. The questionnaire consisted of 13 closed-ended questions addressing demographic characteristics, anesthetic management and blood pressure management, including preoperative thresholds for postponement of elective surgery and intraoperative thresholds for pharmacological treatment of hypotension. The survey was distributed via social media platforms. Participation was anonymous and voluntary. Results: A total of 71 anesthesiologists participated in the study. The most commonly used intubation device was the Macintosh laryngoscope (57.7%), while videolaryngoscopy was used by 42.2% of respondents. Positive end-expiratory pressure (PEEP) was routinely applied by most respondents, with 63.4% adjusting its level according to patient body weight. Multimodal analgesia components were commonly used, with paracetamol (95.8%), dexamethasone (91.5%), metamizole (90.1%), and lignocaine (84.5%) being the most frequently administered drugs. Most anesthesiologists reported postponing elective surgery when blood pressure exceeded 180/110 mmHg. More experienced anesthesiologists more often considered lower thresholds for postponement of elective surgery (p = 0.006). Conclusions: Reported practices among surveyed anesthesiologists for MBS in Poland are generally consistent with international recommendations, particularly regarding the use of PEEP. However, variability remains in airway management strategies and the use of videolaryngoscopy, highlighting the need for continued education and broader implementation of evidence-based perioperative protocols.

Suicide is commonly approached through clinical and psychological frameworks centred on the individual, alongside social explanations emphasising collective conditions. These perspectives offer complementary leverage for understanding and preventing suicidal behaviour. Between these levels, a clinically decisive segment can be specified with greater precision for psychiatric practice, namely the processes through which suffering becomes speakable, socially legitimate and clinically actionable, or is displaced into self-censorship, isolation and delayed help-seeking. This paper advances a service-facing biosemiotic model of suicide risk that formalises this segment as a communicative infrastructure and links it to the public circulation of suicide narratives across media and digital environments. The model comprises two coupled modules. The first, the communicative-classification module, characterises labelling and delegitimation operations that allocate epistemic credibility to crisis talk, foster self-stigma and increase the social cost of disclosing suffering. The second, the public-feedback module, specifies how media representation and repetition regulate the symbolic availability of narrative scripts, with closure- and openness-oriented configurations positioned along the Werther–Papageno continuum. Coupling the modules yields testable propositions concerning mediation via anticipated sanction and moderation by stigma and speakability and identifies conditions under which protective content may show limited translation into help-seeking behaviour. Implications are outlined for how the model may inform therapeutic risk assessment, continuity of care, and prevention. These implications are framed as hypotheses and implementation-relevant considerations derived from the model, with emphasis on (i) operationalising speakability as a clinically evaluable dimension, (ii) identifying institutional conditions that may reduce the communicative cost of help-seeking, and (iii) aligning public communication strategies with international reporting standards. The model is intended to support future empirical testing rather than to establish effectiveness at this stage. Full article

Contact with nature is increasingly recognized as a potential way to enhance prosocial outcomes, yet causal evidence and boundary conditions remain unclear. This meta-analysis synthesized 29 independent experiments (derived from the 19 included reports; N = 4520) examining the effects of short-term nature exposure on prosocial outcomes. Overall, short-term nature exposure produced a significant small-to-medium effect (Hedges’ g = 0.46), robust across sensitivity analyses. Heterogeneity was low (I² = 16.45%), and pre-specified moderator analyses, including exposure modality (media-based, unstructured direct, structured direct), outcome measurement type (behavioral tasks, observed behavior, self-report), and sample characteristics, were largely non-significant, suggesting that the observed effect may generalize across these methodological and demographic factors. These findings provide experimental evidence that short-term nature exposure can reliably enhance prosocial outcomes, with implications for interventions promoting social cohesion in increasingly urbanized societies.

Big-data analytics are increasingly used in scouting and talent identification, with machine learning (ML) tools applied to evaluate and predict player performance based on match statistics, video tracking, physical and anthropometric tests, psychological assessments, social media data, and qualitative scouting reports. Advances in computer vision, together with the emergence of affordable automated broadcasting and data collection systems, have extended the deployment of ML-driven scouting from professional to youth sport. The use of algorithms in educational, employment, and healthcare settings has been shown to introduce biases and discrimination while wrongly assuming accuracy and objectivity because the decisions are made automatically and quantitatively. In this respect, we briefly describe the development of data-driven performance analysis and how ML-based technologies are currently applied for early screening and comparison of large player populations. Based on a narrative overview of the literature, we draw on evidence from education, employment, and healthcare to identify risks that may also emerge in ML-driven player evaluation, including algorithmic bias, non-representative training data, privacy concerns, and the persistence of model-based labels over time, especially in youth sport. Our main contribution is translating these threats into governance principles and operational safeguards for responsible use of AI in scouting and talent identification. Full article

Background/Objectives: There is a seemingly high prevalence of dietary supplement use in the kidney stone population. We aimed to understand patients’ perceptions of dietary supplements and their role in the management of kidney stones. Methods: We performed a standardized survey of patients presenting for management of kidney stones. We investigated the knowledge and use of apple cider vinegar (ACV), turmeric, and cranberry extract, as well as opinions on the safety of dietary supplements and sources of information. Descriptive statistics were used to summarize demographic and survey data. Results: Ninety-five patients were surveyed; 18 (18.9%) patients reported using ACV, 19 (20%) reported using cranberry extract, and 11 (11.6%) reported using turmeric. Similar numbers reported having heard of these dietary supplements being used for kidney stone prevention and/or treatment. Most patients believed these dietary supplements to be probably (ACV, n = 61, 64.2%; cranberry, n = 62, 65.3%; turmeric, n = 61, 64.2%) or definitely (ACV, n = 22, 23.2%; cranberry, n = 28; 29.5%; turmeric, n = 22, 23.2%) safe. For those who had heard about these supplements being used to treat or prevent kidney stones, friends/family (n = 25, 26.3%), online websites (n = 21, 22.1%), and social media (n = 15, 15.8%) were the most common sources of information. Conclusions: Apple cider vinegar, turmeric and cranberry extract have unknown risks or benefits in the management of kidney stones. Furthermore, their impact on stone pathophysiology remains unclear; however, many of our surveyed patient population uses them. Our study provides insight into patients’ use and perception of dietary supplements that clinicians should consider in the management of kidney stones. Further studies are needed to better counsel patients on the safety and efficacy of dietary supplements. Full article

Digital commerce ecosystems increasingly depend on the alignment between social media advertising formats and digital payment systems, yet existing research has examined these mechanisms in isolation, overlooking their combined influence on consumer behaviour, conversion, and long-term value creation. This study addresses that gap by developing an integrative conceptual framework that examines how advertising formats and payment infrastructures jointly shape sustainable digital monetisation within an Environmental, Social, and Governance (ESG) framework. Methodologically, the study adopts a structured narrative literature review of interdisciplinary peer-reviewed studies and selected high-quality institutional reports, drawn from Scopus, Web of Science Core Collection, and Google Scholar, covering publications from 2015 to April 2026. A four-stage PRISMA-adapted selection protocol was applied to ensure transparency, replicability, and analytical rigour across the review process. The findings demonstrate that advertising formats including native advertising, influencer marketing, user-generated content, short-form video, live streaming, and augmented reality drive consumer attention and purchase intention, while payment systems encompassing digital wallets, BNPL services, and in-platform checkout shape transactional trust and friction. Conversion and customer lifetime value emerge as joint outcomes of this interaction, mediated by consumer trust and transaction friction. The study further identifies key sustainability tensions related to digital carbon footprints from data-intensive formats, financial vulnerability associated with frictionless credit tools, and governance concerns surrounding transparency, privacy, and platform power concentration. The study contributes an integrative conceptual model linking advertising formats, payment systems, consumer behaviour, and ESG dimensions within a unified framework, supported by six theoretically grounded hypotheses (H1–H6) to guide future empirical research in sustainable digital commerce.

Background: Problematic smartphone use has been increasingly reported among university students, including nursing students, yet the availability of brief, culturally appropriate, and psychometrically sound assessment instruments in Greece remains limited. Aim: This study aimed to translate and culturally adapt the Greek version of the Smartphone Addiction Scale—Short Version (SAS-SV) and to evaluate its psychometric properties, including internal structure, reliability, and convergent validity with the Mobile Phone Problem Use Scale-10, among nursing students in Greece. Methods: In a cross-sectional study, nursing students from multiple departments across Greece (N = 331) completed the Greek SAS-SV, distributed online via official university forums, student groups, and institutional social media pages, between September 2025 and November 2025. We conducted exploratory and confirmatory factor analyses using polychoric correlations, examined convergent validity, performed exploratory comparisons across demographic characteristics, and estimated the reliability of the SAS-SV. Results: Confirmatory factor analysis was consistent with a one-factor structure and showed acceptable model fit. Internal consistency was high (Cronbach’s α was 0.862 and McDonald’s omega was 0.891), with supportive evidence of convergent validity through its correlation with the MPPUS-10 (Spearman’s ρ = 0.772, p < 0.001). Conclusions: The Greek SAS-SV showed acceptable psychometric properties among nursing students and seems appropriate for research purposes in Greece. Full article

In a media ecosystem marked by misinformation and disinformation, democratic resilience requires new strategies for digital and media literacy and participation. In the proposed model, the University, through transnational Cooperation Partnerships, activates applied research laboratories that generate high-social-impact communication prototypes. The European case studies Respectnet and DigiFunCollab demonstrate that the conscious use of digital media, transforming students from passive users into conscious creators, reduces vulnerability to cognitive biases, filter bubbles, and echo chambers, thereby limiting manipulation in democratic processes and stimulating civic participation. The imitative diffusion of such practices generates virtuous circles of collective learning. The theoretical framework combines institutional isomorphism, reinterpreted as a virtuous isomorphism of best practices, with democratic resilience and the UNESCO MIL and DigComp 2.2 frameworks. The methodology adopts a mixed-methods design with a quantitative prevalence. The qualitative phase includes focus groups with national stakeholders and a national report (regulatory analysis, training needs, SWOT on social entrepreneurship) preliminary to course design. The quantitative phase involves monitoring training pathways (online course and project work) and a final questionnaire. Indicators include the number of participants, certifications, projects developed, and engagement levels. By systematically implementing this approach, the Academy fuels multi-stakeholder institutional dialogue. Knowledge transfer creates communicative culture and strengthens the democratic capacity of communities. This approach confirms the role of Visual Education as a tool to integrate the University’s three missions, thus structurally reinforcing democratic resilience. Full article
