Makerspaces can serve as distributed urban infrastructures for repair, reuse, tool sharing, and peer learning, yet their contributions to circular economy (CE) goals often occur without being explicitly recognized or framed as CE practices. Inspired by practice theory and the literature on quiet sustainability, this study introduces implicit circularity as circular practices enacted without an explicit sustainability/CE framing by participants, and examines how such practices shape bottom-up circular transitions. Using reflexive thematic analysis informed by constructivist grounded theory procedures, we examined three linked questions: which circular practices occur in makerspaces and how they cluster into domains, how these practices vary across makerspace types, and which barriers and governance arrangements shape makerspaces’ consolidation as circular urban infrastructure. A qualitative multi-method design was employed in Czechia, combining field mapping with in-depth qualitative inquiry. Data included 40 semi-structured interviews with makerspace founders and operators, documentary analysis based on websites, social media, event listings, rules, and other documents, and 21 observations. Using reflexive thematic analysis informed by constructivist grounded theory procedures, we analyzed how circular practices cluster into domains, how implicit versus explicit circularity varies across makerspace types, which barriers constrain makerspaces’ consolidation as circular urban infrastructure, and what governance arrangements could mitigate them. Circularity was dominated by implicit, routine practices rather than formal, CE-branded programs. Three practice domains were identified: repair and maintenance, material flows, and learning/education. Explicit programming was comparatively less common and context-dependent. Barriers formed a reinforcing system spanning institutional fragmentation and coordination deficits, capability gaps, infrastructural constraints, and tensions around autonomy and legitimacy, which together kept many circular contributions low-visibility. Makerspaces constitute an under-recognized form of circular micro-infrastructure that couples technical capacity with social learning and can translate CE ambitions into everyday practice. To mobilize these latent capacities, cities need hybrid governance, especially light-touch coordination platforms, long-horizon operational support, and integration of makerspaces into municipal material-flow systems and repair/reuse strategies. The study offers a practice-based framework and a cross-case typology to support comparative research and grounded urban CE policy design. Full article

Digital transformation (DT) is becoming of strategic importance for Small, Medium and Micro Enterprises (SMMEs), especially in the retail sector, where a significant portion of customer engagement, operational efficiency, and market competitiveness is shaped by digital technologies. Even though there is a growing availability of smartphones, mobile payment systems, and social media platforms, many South African retail SMMEs struggle to achieve a sustained and meaningful DT. Existing studies offer limited insights into the dynamic interactions between technological, organisational, and human agency factors that enable digital uptake over time. This study investigates the sociotechnical dynamics of DT among retail SMMEs in the Eastern and Western Cape provinces of South Africa. The research integrates Adaptive Structuration Theory (AST) with the Limits to Success Archetype (LSA) to conceptualise DT as an evolving process shaped by the interplay of technology, organisational structures (formal arrangement of roles, responsibilities, authority, and communication patterns within an organisation), and human agency. Using an exploratory qualitative research design, purposively sampled semi-structured interviews were conducted with 23 retail owners, directors and managers. The interviews were transcribed, and the data were analysed thematically using the Braun and Clarke six-step thematic analysis framework on Atlas.ti 25. Findings indicate that DT in retail SMMEs is enabled by pragmatic, tool-level digital adoption, training, education, ongoing skill development, alignment with business capacity, regulatory clarity, operational realities, addressing scams, fraud, data security, a user-friendly interface, and the availability of native language digital tools, structural interventions that reduce inequality, and DT ecosystem support. The study contributes to DT scholarship by integrating sociotechnical and systems-thinking perspectives to explain the trajectories of DT in retail SMMEs. It also provides practical insights for policymakers, support institutions, and digital ecosystem actors seeking to democratise DT in emerging-market retail contexts. Full article

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.

The present article employs a discursive and neurocommunicational lens to analyze Donald J. Trump’s discursive playbook. By means of a qualitative approach founded upon Critical Discourse Analysis and framing theory, the present study examines the manner in which the tactics of denial, deflection, and discrediting have structured the politician’s political communication since 2016, throughout his new presidential term. The corpus under scrutiny encompasses a range of sources, including official speeches, social media posts, media coverage, and academic literature. A particular emphasis is placed on the Epstein case, which serves to expose the structural limitations of his rhetorical strategy. The findings demonstrate the efficacy of these tactics in polarized contexts, characterized by the mobilization of emotions such as fear, anger, and victimhood, while reinforcing cognitive biases such as dissonance and confirmation bias. However, in situations involving crises that are characterized by strong social consensus—such as sexual abuse, corruption, or demands for transparency—discursive saturation has been shown to generate contradictions, cognitive fatigue, and psychological reactance, leading to a so-called ‘boomerang effect’. From a neurocommunicational perspective, this phenomenon elucidates the process by which emotional triggers, which initially serve to strengthen audience cohesion, can subsequently act as factors of disaffection and internal fragmentation. The study posits that Trump’s rhetorical populism is contingent on a delicate equilibrium between emotional mobilization and perceived credibility, whose disruption threatens to undermine the stability of his leadership and facilitate the emergence of alternative leadership figures within the MAGA movement.

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 recent years, sustainability reporting has taken on an increasingly important role in corporate strategy discussions. Initially a voluntary tool, it has become a benchmark for measuring and communicating the environmental, social, and economic impacts of organizations in a structured way. In light of the Corporate Sustainability Reporting Directive (CSRD), the research assumes that reporting is a lever for change and organizational innovation. To test the hypothesis, the authors chose to use what is known as a ‘natural experiment’: they observed the experience of a particular type of company, benefit corporations, which are required to publish an annual impact report. The empirical investigation was conducted using content analysis methodology to read the impact reports, websites, and social media channels of the companies, as well as case studies through semi-structured interviews. The findings of this study suggest that sustainability reporting can play a role that goes beyond transparency and compliance. In the cases analyzed, the preparation of the sustainability or impact report appears to function as an organizational coordination mechanism that mobilizes internal and external stakeholders. Through this process, companies progressively develop shared interpretations of sustainability objectives, experiment with measurement practices and introduce organizational changes affecting work organization, production processes and value-chain relationships.

Background/Objectives: Blood donation is a critical component of healthcare systems worldwide, yet donor recruitment remains challenging. This study evaluates the knowledge, attitudes, motivations, and practices (KAP) of blood donation among the general population in Saudi Arabia to identify key barriers and propose targeted interventions. Methods: A cross-sectional study was conducted using a structured, validated questionnaire distributed over five months (December 2022 to April 2023) via social media and in-person recruitment at the Central Blood Bank in Riyadh. A total of 1150 participants aged 18–60 years residing in Saudi Arabia were included in the final analysis. Statistical analysis was performed using SPSS version 22, with p < 0.05 considered significant. Results: Participants demonstrated moderate knowledge (mean score 5.43 ± 1.81 out of 9), with significantly higher scores among males, individuals aged 21–30 years, and those holding a bachelor’s degree. Attitudes toward donation were highly positive (mean score 15.46 ± 2.74 out of 20) and correlated with age, gender, marital status, and occupation. Despite this positive outlook, only 34.96% of participants had donated blood previously, although 95.25% expressed willingness to do so. Primary motivators included mobile donation units (89.22%) and paid leave (89.22%), whereas 51.22% of respondents considered current media campaigns ineffective. Common barriers to donation included health concerns (25.30%), time constraints (12.87%), and fear of needles (7.74%). Conclusions: This study reveals a critical disparity between positive public attitudes and actual donation practices in Saudi Arabia. To enhance donor participation, we recommend implementing convenient donation strategies such as mobile blood drives, workplace incentives, and more effective, culturally tailored educational campaigns. Addressing these factors could help Saudi Arabia improve its voluntary donation rates and ensure a sustainable, safe blood supply. Full article

Background: Nomophobia, the fear of being without a mobile phone, has become an increasing public health concern. While existing theories suggest that smartphones often serve as tools for emotional regulation, the situational mechanisms driving these compensatory behaviors remain under-explored. This study investigated how nomophobia levels interact with daily emotional fluctuations and busyness to influence smartphone-based coping patterns. Methods: We employed an intensive longitudinal approach combining objective smartphone tracking with a 4-week daily diary design. Thirty-seven participants were monitored, yielding 837 daily observations. Smartphone use was categorized into Instant Messaging (IM), Social Media Use (SMU), and Non-social Use (NSU). Multilevel linear regression analyzed the interaction effects on usage metrics. Results: Nomophobia significantly correlated with the duration and frequency of SMU, but not IM or NSU. A significant three-way interaction was observed: individuals with high levels of nomophobia exhibited a significantly increased frequency of overall usage, SMU and NSU when experiencing negative emotions during periods of low busyness. In contrast, low-nomophobia individuals maintained stable usage patterns regardless of situational stressors. Conclusions: By conceptualizing smartphone usage as a behavioral proxy for the coping process, this study provides preliminary evidence that nomophobia is associated with a situation-dependent coping pattern, primarily involving increased social media usage. These findings underscore the importance of integrating situational contexts and underlying coping processes to better understand and manage problematic smartphone use. Full article

Global transition toward sustainable micro-mobility is an essential aspect of Saudi Vision 2030; however, high car dependency remains a significant barrier to public health and safety targets. In this context, this study explores the factors determining the adoption of electric bicycles (e-bikes) in Al-Qunfudhah, Saudi Arabia. The present research used a convenience sampling strategy through an online survey conducted via social media and texting, utilizing a designed questionnaire of 10 sections delivered to 171 participants, alongside a 5-point Likert scale. Additionally, the scientific validation and analysis were conducted utilizing internal consistency, validity and scale reliability via statistical analysis. The findings indicated a significant intention–action disparity; while respondents demonstrate a strong psychological intention to adopt e-bikes within 12 months (an average of 3.51), real household ownership was relatively low at 11.1%. In addition, a significant 71.9% of participants use private vehicles for short-distance travel (<5 km), influenced by an average bus stop distance of 21.22 km. The hierarchy of barriers indicates infrastructure and security as the main barrier, particularly the absence of dedicated bike lanes, and concerns regarding traffic safety. In contrast, a perception of physical fitness, and interpersonal interaction behave as significant facilitators. Public health data reveals an average weekly activity of 109.77 min, significantly lower than worldwide recommendations; however, 66.7% of individuals believe e-bikes may address the difference. The statistical evaluation acknowledged the questionnaire’s robustness, with significant Pearson correlation coefficients (p < 0.01) demonstrating internal consistency validity and Cronbach’s alpha values between 0.71 and 0.88 indicating high scale reliability, demonstrating a scientifically stable framework for assessing the measured behavioral determinants. The research recommends the establishment of shaded, dedicated micro-mobility networks and the enforcement of safety regulations to promote a healthy, multi-modal urban ecosystem. Full article

Food waste in households means that there is a need to recognize the possibilities of balancing activities in the field of obtaining and managing food products. Activities in this area may concern giving away surplus food to others, purchasing local and organic products, limiting shopping activity. Generation Z, which was included in this research, uses new media, including mobile applications, to a greater extent than other generations. The main objective of the research is to recognize and present the food-sustainable behaviors and attitudes of Generation Z consumers. The study used the analysis of source data, which was the basis for formulating four hypotheses. They were verified in empirical studies conducted using the CAWI method. The collected material was analyzed using, among others, the proprietary index of environmentally and socially sustainable behaviors (ESRBI), the Mann-Whitney test. The studies showed that respondents assessed their food behaviors as irresponsible, with women’s assessment being higher than men’s. A positive correlation was demonstrated between the use of food saving applications and the value of the ESRBI index and individual sustainable behaviors. Respondents positively assessed the initiatives of local authorities and housing cooperatives in the area of creating places for sharing food and organizing community gardens. Full article

Understanding the role of trust in shaping pro-ecological behaviour is essential for advancing effective environmental communication, particularly in societies characterized by low institutional credibility. This study examines how different forms of trust—scientific, institutional, mediatic, and interpersonal—predict pro-ecological behaviour in Bulgaria, a context marked by historically low levels of social and institutional trust. Drawing on a nationally representative survey of 1008 adults, participants rated their trust in six sources of environmental information (experts, public servants, politicians, media, social networks, and friends or relatives) and reported their engagement in various ecological practices. Multiple regression analysis revealed that trust in experts was the strongest positive predictor of pro-ecological behaviour, followed by trust in friends and relatives. Trust in political institutions, media, and online social networks showed no significant associations. These findings suggest that in low-trust societies, interpersonal trust and trust in experts serve as primary drivers of ecological engagement, while institutional trust alone is insufficient to mobilize collective environmental action. The study underscores the importance of fostering both scientific credibility and community-based communication to enhance public participation in sustainability initiatives. Full article

With the rapid development in new media and social platforms on the internet, some social hotspots or sensitive events can easily ferment and spread in the online space, attracting the attention or concentrated discussion of young students. Network cluster behavior is a collective behavior in which a large number of netizens collectively express and gather opinions around social hot issues of common concern, creating online public opinion. The study explored the influence of group psychology on the process of college students participating in online cluster behavior. A survey was conducted involving 2137 college students from over 10 universities in Zhejiang Province, Jiangsu Province, and other regions. The data were analyzed using correlation analysis and moderated mediation model testing. This study found that group psychological factors, such as emotional infection, depersonalization, the spiral of silence, relative deprivation, group polarization, and action mobilization, positively predicted network cluster behavior. The action mobilization of opinion leaders mediated the relationship between emotional infection and network cluster behavior. Group polarization mediated the relationship between the spiral of silence and network cluster behavior. Additionally, group efficacy moderated the latter part of the mediation process between group polarization and network cluster behavior. Full article

In classic communication systems, signals and data were mostly continuous in time, such as voice (fixed and mobile telephony, and radio systems) and video signals (Television services), Conversely, in modern communication systems, most signals are packet-based (text and images in messaging services and social media) and even continuous-time data has to be converted into a discrete-time nature data, such as video and voice services that are now discretized to be sent in packet-based communication systems. However, these classic communication systems were analyzed, studied, and designed using continuous-time analysis, such as the classic Erlang-B formula. This classic analysis can still be used in modern systems, but a discrete-based framework provides a seamless analysis and yields more accurate results. In this work, the effect of the system’s elementary time step is analyzed, and guidelines for its selection are provided to adequately analyze continuous-time systems within a discrete-time framework. To demonstrate the utility of the discretization and to consider these guidelines, we developed a mathematical analysis based on a discrete-time Markov chain to study a system with a buffer capacity under conventional and bursty traffic, which is commonly found in an Internet of Things application. The derived formulas allow us to quantify system performance under a discrete framework. This, in turn, allows us to provide some relevant guidelines for the elementary time step selection to adequately analyze continuous-time systems under a discrete-time framework. Full article

Mass media plays a key role in helping audiences organize facts and make sense of uncertainty, particularly during emerging medical crises when pre-existing knowledge is limited. The COVID-19 pandemic was the first major global crisis in the modern communications era in which traditional media (TV, radio, newspapers and major news sites) and social media (especially Facebook groups) both functioned as high-reach information systems, shaping public interpretation in parallel. Social media, especially closed and semi-closed Facebook groups, became a central arena for discussion, community building, and the circulation of alternative interpretations. Against this backdrop, the current study examines how anti-vaccination activists (anti-vaxxers) who are active in anti-vaccine Facebook groups perceive mainstream media coverage of COVID-19. The study employs a qualitative design based on semi-structured in-depth interviews with 70 anti-vaxxers of both genders who were active participants in anti-vaccination Facebook groups. Findings indicate that participants perceive mainstream media as advancing a biased, unidimensional narrative aligned with governmental, economic, and political interests, and as delegitimizing dissenting voices. Consistent with the hostile media effect, interviewees interpret coverage as hostile toward their community, which intensifies their tendency to avoid mainstream news and rely on Facebook group networks for validation, interpretation, and mobilization. These results highlight how crisis coverage is experienced by marginal groups and how social media group dynamics can reinforce perceptions of media hostility and deepen informational polarization.
