This study compares complaints in Korean and Chinese, focusing on how they are expressed explicitly or implicitly. Complaints are potentially face-threatening, yet they frequently appear in conversations among native Korean and Chinese speakers who are characterized as upholding Neo-Confucian values and emphasizing social harmony. Although some contrastive studies have examined complaints across languages, none have specifically investigated the explicit and implicit strategies employed in Korean and Chinese complaint discourse. Given the growing intercultural contact between Korean and Chinese speakers, this gap calls for closer attention. To address this, the present study explores how native Korean and Chinese speakers articulate complaints in the Korean and Chinese versions of the travel reality show Sisters Over Flowers. Sixteen episodes were analyzed using interactional sociolinguistic methods, incorporating both qualitative and quantitative approaches. The analysis uncovered both explicit and implicit strategies (e.g., expressions of annoyance or disapproval, overt grievances, questions, advice, teasing, and hints). Notably, the Korean participants produced significantly fewer complaints than their Chinese counterparts. These findings offer theoretical and practical insights. Theoretically, the results challenge overly broad notions of East–West pragmatic distinctions by demonstrating meaningful variation within East Asian cultures. Practically, a better understanding of explicit and implicit complaint strategies in Korean and Chinese can enhance intercultural communication, promote culturally sensitive responses, and bridge misunderstandings in increasingly globalized settings.

Background: Informal welders in Pretoria West face growing occupational safety risks due to hazardous working environments and limited regulatory oversight. Despite the high-risk nature of their work, many remain unaware of relevant safety legislation and inconsistently use personal protective equipment (PPE). This study aimed to investigate the occupational safety risks, challenges, and levels of compliance with safety practices among informal welders in Pretoria West, South Africa. Methods: A cross-sectional mixed-methods approach was employed, incorporating both qualitative and quantitative designs. Data were collected from 40 male welders (aged 20–55 years) using structured questionnaires, observational checklists, and semi-structured interviews. Descriptive statistics were generated using Microsoft Excel, while thematic content analysis was applied to the qualitative data. Results: Eighty-five percent (85%) of welders reported using gas welding, and more than half had received training in welding and PPE use; however, 47.5% had no formal training. A high prevalence of work-related injuries was reported, including burns, cuts, and eye damage. Common safety concerns identified were burns (42.5%), electric shocks (35%), and malfunctioning equipment. Observational data revealed inconsistent PPE use, particularly with flame-resistant overalls and eye protection. Qualitative insights highlighted challenges such as demanding client expectations, hazardous physical environments, and inadequate equipment maintenance. Many sites lacked compliance with occupational safety standards. Conclusion: The study reveals critical gaps in safety knowledge, training, and PPE compliance among informal welders. These deficiencies significantly elevate the risk of occupational injuries. Strengthening occupational health and safety regulations, improving access to PPE, and delivering targeted training interventions are essential to safeguard the well-being of welders and those in their surrounding communities.

Advanced three-dimensional extended reality (XR) technologies are highly suitable for cultural heritage research and education. XR tools enable the creation of realistic virtual or augmented reality applications for curating and disseminating information about cultural artifacts and sites. Developing XR applications for cultural heritage requires interdisciplinary collaboration involving strong teamwork and soft skills to manage user requirements, system specifications, and design cycles. Given the diverse end-users, achieving high precision, accuracy, and efficiency in information management and user experience is crucial. Human–computer interaction (HCI) design and evaluation methods are essential for ensuring usability and return on investment. This article presents ten case studies of cultural heritage software projects, illustrating the interdisciplinary work between computer science and HCI design. Students from institutions such as the State University of New York (USA), Glasgow School of Art (UK), University of Granada (Spain), University of Málaga (Spain), Duy Tan University (Vietnam), Imperial College London (UK), Research University Institute of Communication & Computer Systems (Greece), Technical University of Košice (Slovakia), and Indiana University (USA) contributed to creating, assessing, and improving the usability of these diverse cultural heritage applications. The results include a structured typology of CH XR application scenarios, detailed insights into design and evaluation practices across ten international use cases, and a development framework that supports interdisciplinary collaboration and stakeholder integration in phygital cultural heritage projects.

This study introduces Edible Streets as a distinct and scalable model of community-led urban food growing, specifically investigating the drivers and barriers to the initiative. Unlike traditional urban food-growing initiatives, Edible Streets explores the integration of edible plants into street verges and footpaths with direct community involvement of the people who live/work in a street. This study contributes new knowledge by evaluating Edible Streets through the COM-B model of behavioural change, through policy and governance in addition to behaviour change, and by developing practical frameworks to facilitate its implementation. Focusing on Oxford, the research engaged residents through 17 in-person interviews and 18 online surveys, alongside a stakeholder workshop with 21 policymakers, community leaders, and NGO representatives. Findings revealed strong motivation for Edible Streets, driven by values of sustainability, community resilience, and improved well-being. However, capability barriers, including knowledge gaps in gardening, land-use policies, and food preservation, as well as opportunity constraints related to land access, water availability, and environmental challenges, hindered participation. To address these, a How-to Guide was developed, and a pilot Edible Street project was launched. Future steps include establishing a licensing application model to facilitate urban food growing and conducting a Post-Use Evaluation and Impact Study. Nationally, this model could support Right to Grow policies, while globally, it aligns with climate resilience and food security goals. Locally grown food enhances biodiversity, reduces carbon footprints, and strengthens social cohesion. By tackling key barriers and scaling solutions, this study provides actionable insights for policymakers and practitioners to create resilient, equitable urban food systems. Full article

All individuals hold beliefs about their ability to successfully perform specific tasks. These beliefs, known as self-efficacy, play a key role in guiding and motivating human behavior. In education, both teachers’ self-efficacy beliefs and the collective efficacy shared by teachers within a school have been linked to improved performance, well-being, and job satisfaction among students and educators. While these constructs have been widely studied in various countries and contexts, little is known about them in Mexico, the country with the largest Spanish-speaking population worldwide. This study is the first to examine the relationship between teacher self-efficacy (TSE), collective efficacy, and other teacher- and school-level variables in Mexico. Given the absence of psychometrically robust instruments to assess collective efficacy among Spanish-speaking teachers, the Collective Teacher Beliefs Scale (CTBS) was first adapted into Spanish, and its psychometric properties were evaluated. Subsequently, multilevel analyses incorporating teacher- and school-level factors revealed that professional development on multicultural communication, classroom autonomy, and collaboration, at the teacher level, and collective efficacy and stakeholder participation, at the school level, were significant predictors of TSE. Finally, implications for future practice and policy are discussed. Full article

Tinos Island, part of the Cyclades Complex in the central Aegean Sea, represents a distinctive case of geocultural heritage where geological formations and cultural identity intersect. This study evaluates the geoeducational and geotouristic potential of Tinos’ geosites using GEOAM methodology, which assesses their scientific, educational, and conservation value. Six geosites are examined to explore their geoeducational potential, including prominent locations such as the Tafoni formations and the Exombourgo granite massif. The findings highlight the significance of these sites, while also identifying challenges related to infrastructure, stakeholder engagement, and sustainable management. By integrating geoethics into geotourism practices, Tinos can adopt a balanced approach that enhances environmental conservation alongside community-driven economic benefits. The study underscores the need for collaborative initiatives to optimize the island’s geoheritage for education and tourism, ensuring its long-term preservation. Geotourism, when responsibly implemented, has the potential to strengthen local identity while advancing sustainable tourism development. Full article

High-speed communication can be achieved using laser inter-satellite links. However, laser terminals are highly sensitive to environmental conditions, which can lead to link disconnections. Therefore, an acquisition method capable of determining pointing errors is essential. In this study, a fast space–time fusion acquisition method was developed. This method establishes the relationship between satellite position, capture time, and azimuth and elevation angles. The performance of the proposed acquisition time optimization method was verified in a practical engineering application. Experimental results show that the pointing error was reduced by five times, the acquisition rate increased by 40%, the acquisition speed improved by 300 times, and multiple interference factors were effectively addressed.

This study examines the political and elite motives behind Colombo’s ‘world-class city’ initiative and its impact on public housing in underserved communities. Informed by interviews with high-ranking government officials, including urban planning experts and military officers, this study examines how President Rajapaksa’s elite-driven postwar Sri Lankan government leveraged military capacities within the neoliberal developmental framework to transform Colombo’s urban space for political and economic goals, often at the expense of marginalized communities. Applying a contextual discourse analysis model, which views discourse as a constellation of arguments within a specific context, we critically analyzed interview discussions to clarify the rationale behind the militarized approach to public housing while highlighting its contradictions, including the displacement of underserved communities and the ethical concerns associated with compulsory relocation. The findings suggest that Colombo’s postwar public housing program was utilized to consolidate authoritarian control and promote speculative urban transformation, treating public housing as a secondary aspect of broader political and economic agendas. Anchored in militarized urban governance, these elite-driven strategies failed to achieve their anticipated economic objectives and deepened socio-spatial inequalities, raising serious concerns about exclusionary and undemocratic planning practices. The paper recommends that future urban planning strike a balance between economic objectives and principles of spatial justice, inclusion, and participatory governance, promoting democratic and socially equitable urban development.

Past archaeological practices have resulted in a distorted history of Native American cultures based upon western-biased research. This has been especially apparent in the rock art of the Klamath Basin in southern Oregon and northern California. In response to this, Native and non-Native scholars are striving to develop a counter-discourse that both challenges and replaces western constructs in research on Native American communities. The result of this approach is a growing trend within the discipline that has come to be called “Indigenous Archaeology.” Critical to this approach is that Native voices are transported from the margins of the research to its center, where they are intended to replace the Western colonialist narrative. Unfortunately, Native American tribal communities have been the targets of federal assimilation policies for the past few centuries, and as a result, much of their cultural knowledge unwittingly carries forward this distorted past. In this paper I explore a framework built upon ethnographic accounts of shamanism and rock art, along with a robust familiarity with local myth, and how this provides a foundation of traditional cultural knowledge against which to compare and evaluate the interpretive statements made in contemporary tribal members about rock art and other sacred material culture.

This article discusses caste dynamics within the Punjabi diaspora in Italy—the largest in the EU—by focusing on the case of the Ravidassia community and describing its evolving relations with the local Sikh community. Previous research on Punjabi migration to Italy mainly focused on issues of labor exploitation, intermediation, and Sikh identity, often conflating the entire Punjabi population with its majoritarian—but far from exclusive—Sikh-Jatt component, thereby overlooking its internal heterogeneity of caste, religion, and class. Despite the growing number of Ravidassia-Chamar migrants in Italy—evidenced by the proliferation of Ravidassia temples and associations across the country—their migratory experiences, employment patterns, socioreligious practices, and inter-caste relationships remained unexplored. This article offers, for the first time, an overview of the history, geography, and identity politics of the Ravidassia in Italy. Drawing on data collected with Punjabi migrants during multi-sited ethnographic fieldwork, it illustrates the alternative strategies adopted by the Ravidassia to assert their identity in this diasporic context, focusing on cases in which their relations with the Sikh manifested their complex nature. It concludes by discussing the advantages and drawbacks of each strategy, in light of the history of power relations between the Ravidassia and the Sikh. Full article

This study explores the relationship between institutional shareholders and climate-related disclosure (CRD) and how sustainability committees influence this relationship among publicly listed Malaysian firms. For the analysis, 990 firm-year observations were studied from 198 highly polluting firms from 2021 to 2024. A strong CRD index was designed using the recognized climate reporting frameworks and well-grounded literature to assess the level of climate-related disclosure. Fixed-effects and hierarchical panel regression models show that CRD increases when institutional investor ownership increases, meaning firms with more institutional investors disclose more information on climate-related topics. In addition, a sustainability committee at the board level greatly improves this relationship by highlighting the positive impact of strong internal governance. As a result, such committees establish climate management and improve communication with investors, making the firm’s actions more transparent. The findings of this study are consistent with agency and legitimacy theories because institutional investors assist in monitoring firms’ environmental performance, and sustainability committees help the company maintain these standards internally. Further, this study helps grow the understanding of corporate governance (CG) and sustainability by pointing out that the presence of institutional owners and sustainability committees can promote openness about climate matters. Accordingly, these findings can guide policymakers, investors, and business leaders in boosting responsible environmental reporting and sustainable business practices in developing countries.

Background: The integration of digital imaging tools in dentistry has transformed clinical workflows, diagnostic accuracy, and patient outcomes. However, less attention has been given to how these tools influence dentists’ self-reported outcomes, including clinical confidence, efficiency, perceived treatment quality, communication, and professional satisfaction. This article aimed at assessing AI-powered digital tools in dentistry and their self-reported impact on dental practitioners’ activity and treatment outcomes. Methods: A comprehensive survey was distributed to 126 dental professionals of different genders, ages, years of experience, and types of dental practice to assess their experiences and attitudes towards AI applications in diagnostics and treatment planning, as well as how patients and dentists perceive the benefits and challenges associated with digital dentistry. Results: Digital photographs and CBCT were regarded as essential tools to have in clinical practice, in contrast with intraoral scanners. However, barriers like high initial costs, specialty differences, and lack of formal training may influence the results. Conclusion: These findings suggest that when used appropriately, AI digital tools can significantly elevate the quality of clinical practice and professional fulfillment and underscore the importance of tailored training programs and supportive infrastructures to facilitate the effective integration of digital technologies in dental practice.

Currently, high-tech assistive technologies (ATs), particularly Socially Assistive Robots (SARs), virtual reality (VR) and conversational AI (ConvAI), are considered very useful in supporting professionals in Speech and Language Therapy (SLT) for children with communication disorders. However, despite a positive public perception, therapists face difficulties when integrating these technologies into practice due to technical challenges and a lack of user-friendly interfaces. To address this gap, a design-based research approach has been employed to streamline the integration of SARs, VR and ConvAI in SLT, and a new software platform called “ATLog” has been developed for designing interactive and playful learning scenarios with ATs. ATLog’s main features include visual-based programming with graphical interface, enabling therapists to intuitively create personalized interactive scenarios without advanced programming skills. The platform follows a subprocess-oriented design, breaking down SAR skills and VR scenarios into microskills represented by pre-programmed graphical blocks, tailored to specific treatment domains, therapy goals, and language skill levels. The ATLog platform was evaluated by 27 SLT experts using the Technology Acceptance Model (TAM) and System Usability Scale (SUS) questionnaires, extended with additional questions specifically focused on ATLog structure and functionalities. According to the SUS results, most of the experts (74%) evaluated ATLog with grades over 70, indicating high acceptance of its usability. Over half (52%) of the experts rated the additional questions focused on ATLog’s structure and functionalities in the A range (90–100), while 26% rated them in the B range (80–89), showing strong acceptance of the platform for creating and running personalized interactive scenarios with ATs. According to the TAM results, experts gave high grades for both perceived usefulness (44% in the A range) and perceived ease of use (63% in the A range). Full article

Petroleum-contaminated soil is an increasingly severe environmental issue. The integration of phytoremediation and microbial remediation can effectively mitigate their individual limitations and enhance remediation efficiency. In this study, four newly isolated bacterial strains (including Cytobacillus and Rhodococcus) that exhibited preferential degradation of distinct petroleum components were combined with the rhamnolipid-producing strain Pseudomonas aeruginosa SL-1. The immobilization of this petroleum-degrading microbial consortium was performed by biochar adsorption and sodium alginate embedding, subsequently optimized using response surface methodology (0.75 g·L⁻¹ of biochar, 40 g·L⁻¹ of sodium alginate, and 40 g·L⁻¹ of calcium chloride). The results showed that the highest petroleum degradation rate (97.1%) of immobilized bacterial consortium was achieved at 72 h at a petroleum concentration of 5.0 g·L⁻¹. When combined with Sudan grass for soil bioremediation, the degradation rate reached 72.8% after 120 d for soil containing 5.0 g·kg⁻¹ of petroleum, higher than the results for the treatments with only immobilized bacterial consortium (53.0%) or Sudan grass (49.2%). Furthermore, significant improvements were observed for soil pH; nitrogen, phosphorus, and potassium contents; and urease, dehydrogenase, and catalase activities. Composite treatment also significantly increased the diversity and richness of the soil bacterial community and regulated its structure, function, and network composition. This study offers theoretical insights and potential practical applications for the enhanced bioremediation of petroleum-contaminated soils. Full article
