The educational process of developing web design competence remains a persistent challenge for many students and educators, particularly in developing countries where conventional teaching methodologies and assessment models often fall short in promoting higher-order thinking and problem-solving. In this study, we respond to the call for innovative assessment approaches by examining the impacts of assessment models on a web design and development course and students’ cognitive load when adopting the AI-assisted assessment model (AAAM) compared to the traditional assessment model (TAM). We employed a mixed-methods research approach, incorporating a quasi-experimental, non-equivalent pretest–posttest control group design and a qualitative component, involving 63 undergraduate students enrolled in CRE 625. The intervention lasted approximately 10 weeks and focused on web design and development across two universities in a developing country. Consistent with quasi-experimental principles, students were assigned to treatment groups based on pre-existing institutional class structures, thereby controlling allocation using criteria rather than randomization. Two validated instruments were used to assess students’ web design and development competence (WDDC) and cognitive load (CL), and the data were analyzed using ANCOVA to evaluate performance gains and the interaction effect with gender.

Sustainable energy systems (SESs) support intelligent modeling, automation, and governance that enable energy access, infrastructure innovation, and climate resilience. Despite their potential, their integration with large language models (LLMs) raises concerns regarding energy intensity, transparency, equity, and regulation. This study adopts a mixed-methods review combining a BERTopic-based thematic analysis and case-based synthesis to examine applications of LLMs in energy modeling, optimization, etc., and to assess their alignment with the United Nations Sustainable Development Goals. These applications support SDG 7 (Affordable and Clean Energy) by improving access to energy knowledge and decision support, SDG 9 (Industry, Innovation and Infrastructure) through intelligent and scalable digital infrastructure, and SDG 13 (Climate Action) by climate-responsive planning and operational efficiency. The findings reveal that modular, agent-based LLM workflows enhance energy modeling and regulatory compliance. However, sustainability trade-offs necessitate responsible Artificial Intelligence (AI) governance emphasizing transparency, ethical design, and inclusivity. This review informs policy and practice by suggesting that LLMs offer potential value for sustainable energy application deployment within responsible AI governance frameworks that emphasize ethical design, accountability, and equitable access. The study provides future research directions using the ADO (antecedents–decisions–outcomes) framework, emphasizing regulatory readiness, ethical design, and inclusive governance aligned with SDGs 7, 9, and 13, among others.

The integration of digital tools into mathematics education has the potential to transform teaching and learning for students with special needs by fostering inclusion, accessibility, and engagement. Guided by the principles of Universal Design for Learning (UDL) and Vygotsky’s social constructivist theory, this study investigates how digital technologies can enhance learning experiences and promote inclusive education in mathematics classrooms. Using a mixed-method design, data were collected from 110 mathematics teachers and 210 Grade 11 students in special schools across Nigeria to assess the availability, utilization, and impact of digital tools on students’ engagement, motivation, collaboration, and problem-solving. Findings indicate that while access to digital tools remains limited, their effective use significantly improves students’ learning experiences and supports inclusive pedagogical practices. The study underscores the importance of policy alignment to ensure equitable access to digital resources for all students. Findings contribute to global discussions on inclusive digital pedagogies by providing empirical insights into how technology can mediate participation, interaction, and achievement in mathematics for students with special needs.

Amid rapid urbanization in China, widespread gated residential districts have created physical and visual isolation from surrounding nature, undermining environmental benefits and daily accessibility. The emergence of a twenty-first-century “sharing” paradigm reshapes how buildings and landscapes are used and experienced, opening new opportunities for diversified sharing between communities and natural systems. Yet, despite mature research on city-scale landscape sharing, micro-scale tools to balance sharing versus exclusive route allocation—and to operationalize cross-system sharing-route design—remain limited. This study examines nature-integrated community design through the Landscape Route Sharing Ratio (LRSR), a metric derived from the Length and Density of Sharing Landscape Route (L_s/D_s), the Length and Density of Non-shared Landscape Route (L_ns/D_ns). It analyzes eight cases using a mixed-methods approach (field surveys, spatial mapping, planning-document review and quantitative measurement), and identifies five core cross-system features through typological analysis: extension to surrounding landscapes (ENL), cross-boundary landscape axes (CBLA), multi-scale hierarchy (MSH), multi-elevation systems (MES), and non-motorized priority (NMP). This study demonstrates that higher LRSR values significantly enhance landscape integration and pedestrian experiences. By establishing actionable target ranges (0.50–0.70), the research provides a practical decision-support tool for nature-integrated community design, advancing the methodological understanding of how shared routes foster ecological and social vitality in contemporary urban environments. The framework effectively bridges the gap between quantification with design guidance for nature-integrated communities. Full article

Against the background of high-quality development and urban renewal in China, old residential communities have become key areas for improving spatial quality and quality of life. We used the entrance pavilion of Baoshengli North Community as a case study to explore how spatial design and layout can meet residents’ psychological and social needs. Adopting a mixed-methods approach, combining field observation, behavioral mapping, a questionnaire (Total = 105), in-depth interviews, and statistical analysis, a post-occupancy evaluation (POE) was conducted on spatial effectiveness and social functions. The results show that user-oriented spatial design, safety, esthetic quality, and inclusive functions significantly enhance residents’ spatial perception, willingness to use the space, and social interaction. Differentiated spatial preferences and potential conflicts among diverse resident groups were also identified. Targeted design interventions can effectively strengthen the connection between spatial use and subjective perception, and participatory and equitable strategies help promote social harmony and justice. This study enriches the post-occupancy evaluation system for the renewal of old communities from psychological and social dimensions, and provides practical references for user-centered, inclusive, and sustainable public space design in urban renewal practices. One limitation of this study is that data were collected over a single period, which restricts the analysis of seasonal impacts on spatial usage. Full article

Illegal artisanal and small-scale mining (galamsey) and climate stress jointly degrade ecosystems and livelihoods in Ghana. This paper demonstrates how community-driven governance can realign incentives toward environmental stewardship and inclusive livelihoods. Using an explanatory sequential mixed-methods design—quantitative difference-in-differences followed by qualitative case analysis and Participatory Action Research—we evaluate a structured program combining vocational training, financial literacy, environmental stewardship, and governance alignment. We operationalize Environmental, Social, and Governance (ESG) outcomes via transparent composite indices and triangulate survey, administrative, and focus group evidence. The study identifies conditions under which alternative livelihoods reduce participation in illegal mining, strengthen women’s economic agency, and improve adoption of climate-smart practices. Implications include practical guidance for program design (community delivery, matched incentives, oversight), policy (local climate finance and accountability mechanisms), and research (scalable indicators and rigorous impact evaluation in resource-dependent communities).

Cartilage regeneration remains an unmet clinical challenge. Despite the great advances in the production of hydrogels as support matrices for cartilage regeneration, the resulting mechanical properties remain low. Granular composite hydrogels appear as ideal candidates due to their injectability and modularity in design. Here, we report on the fabrication and characterization of heterogeneous composite granular hydrogels based on methacrylated chitosan (CHIMA) and gelatin (GelMA) microparticles supported by an interstitial methacrylated alginate (ALMA) matrix. Microparticles were prepared by an oil-emulsion method and their size and morphology optimized, resulting in CHIMA and GelMA microparticles of 10.8 µm (95% CI 9.2, 13.1) and 115.8 µm (95% CI 107.5, 137.6) in diameter, respectively. The microparticles were mixed with ALMA and crosslinked to form granular hydrogels that demonstrated reduced swelling and weight loss. The storage modulus increased from 33 to 66.4 kPa for CHIMA/ALMA hydrogels and from 11.5 to 19.5 kPa for GelMA/ALMA hydrogels when the particle concentration increased from 10 to 50%, and was higher than traditional ALMA hydrogels. Hydrogels of 50:50 CHIMA:GelMA permitted a 6.6-fold increase in cell number after 28 days of culture, and promoted the chondrogenic differentiation of embedded mouse mesenchymal stem cells with a glycosaminoglycan deposition of over 15 µg and the expression of chondrogenic markers.

Understanding and developing habits in complex systems thinking using STEM-integrated perspectives is essential in addressing education and workforce needs in society. In this study, we investigated a learning intervention that incorporated multiple models designed to improve engineering students’ understanding of complex systems through investigating the mechanobiology of the Venus flytrap. Mechanobiology is a transdisciplinary field that integrates biology, engineering, chemistry, and physics to explore how cells and tissues sense and respond to forces in their environment. We used an exploratory, mixed-methods approach to examine the impact of this new curriculum on investigating flytrap closure and prey digestion. We then evaluated students’ understanding of complex systems characteristics (i.e., many interacting parts, decentralization, non-linear interactions, emergence, and adaptation) and in their ability to transfer these principles to other systems. Qualitative analyses demonstrate that students articulated key systems principles in relation to their understanding of flytrap mechanobiology, while descriptive summaries of pre- and post-surveys suggest broader conceptual gains. Furthermore, students demonstrated the transfer of systems thinking to other contexts and reported an enhanced understanding of real-world STEM research. Full article

This study explores the impact of implementing a mandatory e-government reform within Indonesia’s national ISBN service (Regulation No. 5/2022). It examines the effects of this policy shift on public service quality and the resulting administrative burden placed on stakeholders, specifically publishers. The study employs an explanatory sequential mixed-methods design (QUAN → qual). The first phase analyzes longitudinal quantitative data from annual Public Satisfaction Surveys (2021–2024). The subsequent qualitative phase analyzes thousands of archival records, including complaint logs and policy memos, to contextually explain the quantitative findings. The results indicate that the reform induced a severe digital shock, causing the Public Satisfaction Index (IKM) to plummet from Good in 2021 to Poor (75.03) in 2022. The most significant declines were observed in the Procedures (2.79/4) and Service Time (2.30/4) indicators. Qualitative analysis reveals that this collapse was driven by specific policy-induced frictions: the mandatory implementation of a Single Account system and the intentional tightening of governance and validation parameters. While limited in statistical generalizability due to its single-case archival design, this study clearly demonstrates that public managers must recognize the inherent trade-off between tightening institutional governance (control) and maintaining public service quality (satisfaction). Proactive friction management and user-centric change management are essential to mitigating such digital shocks. Ultimately, this study offers a unique longitudinal analysis that forensically links quantitative satisfaction metrics with qualitative policy frictions. Full article

Digital inspection technologies are increasingly being adopted in the construction industry to improve efficiency, decision quality, and sustainability performance. Mixed reality (MR) systems can reduce rework, minimise human error, and support resource-efficient inspection processes. However, empirical evidence on how perceptions of efficiency and safety influence professional acceptance of MR technologies remains limited. This study investigates the adoption of MR for construction inspection using an extended technology acceptance model (TAM) that incorporates task efficiency and safety perception as domain-specific human factors. A within-subjects scenario-based experimental design was applied, in which 103 construction professionals evaluated four inspection modalities: HoloLens MR, smart glasses, tablet-based systems, and traditional paper-based methods. Data was analysed using linear mixed-effects models, structural equation modelling, mediation analysis, and dominance analysis. The results show that HoloLens MR achieved the highest perceived efficiency and safety perception, while imposing the lowest cognitive demand. Perceived efficiency was a strong predictor of device preference and significantly predicted perceived usefulness (β = 0.322, p < 0.001), which fully mediated its effect on behavioural intention. Safety perception accounted for a substantial proportion of the variance in user evaluations (η² = 0.237). These findings indicate that sustainable adoption of MR in construction inspection depends on combined perceptions of efficiency gains, usability, and safety support. Full article

Traditional enzyme-induced carbonate precipitation (EICP) technology for brick crack rehabilitation is commonly plagued by solution clogging and low repair efficiency. To overcome these technical limitations, a novel centrifugal cementation method was proposed in this study, with its core innovation lying in decoupling the EICP reaction from the masonry reinforcement process. After the complete reaction of urease with the cementation solution, a high-concentration calcium carbonate colloid was extracted via centrifugation, which was then mixed with fine sand to prepare a repair mortar for direct injection into brick cracks. The experimental results, based on a single-factor design with a fixed soybean powder concentration (180 g/L, peak urease activity), showed that the maximum flexural strength of the repaired bricks reached 2.31 MPa, recovering as much as 122.9% of that of the cracked unrepaired bricks. Furthermore, the flexural strength of the repaired bricks exhibited a significant positive correlation with the calcium carbonate content (20–100%) and curing time (3–28 days). Phase analysis indicated that the repair mortar was primarily composed of calcite and quartz. The high shear force generated by centrifugation triggered explosive nucleation of calcium carbonate, and spherical calcite particles were formed through Ostwald ripening, exhibiting a distinct characteristic of decoupling between the spherical morphology and calcite crystal phase. The centrifugal cementation method proposed in this study achieves excellent short-term repair effects for masonry structures under laboratory conditions, thus providing a novel technical approach for the crack rehabilitation of masonry structures.

Rapid, state-led urbanization in China often generates socio-spatial vulnerabilities, leaving interstitial “waiting lands” in a state of regulatory and ecological limbo. This paper investigates “nomadic gardens”—spontaneous, resident-led cultivation in Jinan—as a bottom-up strategy for adaptive capacity. Using a mixed-methods approach involving site typologies and community surveys (n = 100), we identify eight distinct garden forms that function as socio-ecological buffers, mitigating the risks of social isolation and psychological distress among elderly residents. Findings reveal a significant resilience gap caused by rigid land-use policies that prioritize ornamental aesthetics over functional productivity. We propose an Adaptive Urbanism framework that utilizes modular design and transitional governance to transform these precarious spaces into managed resilience assets. By shifting the planning focus from enforcement to risk-responsive design, this research provides a scalable model for sustainable urban risk management in rapidly transforming global cities.

Background/Objectives: Adequate cardiopulmonary resuscitation (CPR), defibrillation, and treatment of reversible causes are essential for improving the survival of patients suffering from out-of-hospital cardiac arrests (OHCAs). The Advanced Life Support (ALS) algorithm includes reversible causes for cardiac arrest. This study aimed to develop an interactive mobile checklist to identify reversible causes of OHCA (REBECCA) and evaluate their usability and usefulness among emergency physicians. Methods: This mixed-methods study was conducted at the Emergency Medical Service Vienna, Austria. All participants were emergency physicians from the Medical University of Vienna. An interactive mobile checklist was developed using a participatory design approach involving a focus group of 10 emergency physicians. Usability and applicability were assessed using structured questionnaires. Descriptive statistics were used to summarize participant characteristics and evaluation outcomes. Results: Among the included participants, 70% were specialists with a median prehospital experience of 2.0 (1.0–4.3) years. Although most participants were confident about their level of professional experience with OHCA, 85% still found the checklist to be helpful. The majority of the participants preferred the digital checklist over the paper-based checklist and appreciated its integration with the point-of-care ultrasound (POCUS) application. Although the participants did not communicate a significant need for further details on most causes, a small majority favored more information on intoxication and electrolyte disorders. Conclusions: The majority of the included emergency physicians found the REBECCA checklist helpful regardless of training level, whereas almost no physician needed further detailed information on the reversible causes. Our findings underscore the potential importance of future investigations aiming to reduce the cognitive load of emergency physicians during OHCA scenarios. Full article

In Australia and around the world, young students are increasingly experiencing declines in wellbeing, engagement, and sense of belonging. These trends are accompanied by rising anxiety and social disconnection that affect learning and development. In response to these concerns, this study investigated whether a 10-week nature play intervention could support wellbeing, engagement, and learning in Year One students. A quasiexperimental mixed-methods design was used with students (N = 50; mean age = 6.87 years) from a metropolitan public primary school in Sydney, Australia. Participants were allocated to an intervention (n = 25) or a waitlist control group (n = 25). Data was collected at three time points: pre-intervention, post-intervention, and four-month follow-up. Quantitative measures included reading and mathematics results, and a student self-report questionnaire assessing play, nature connection, engagement, and wellbeing. Qualitative data comprised teacher and student journals, teacher interviews, parent surveys, and researcher observations. The results indicated significant improvement in mathematics, alongside children’s reported expressions of joy, autonomy, and emerging awareness of human–nature reciprocity. Despite limitations in sample size and context, these outcomes suggest that nature play supports holistic development while promoting a broader view of education that values wellbeing, engagement, and belonging alongside academic learning.

Rural educators face persistent structural barriers to accessing professional development that supports instructional change, particularly in disciplines such as engineering that require specialized knowledge and resources. This study examines a needs-driven professional development initiative designed to support rural K–12 educators in integrating engineering concepts through a school–university partnership in Southwest Virginia. Using a mixed-methods needs assessment consisting of a regional survey and in-depth interviews with teachers and administrators, we identified key challenges related to professional development access, relevance, and sustainability. These findings informed the design of a two-day professional development workshop grounded in place-based education and teacher pedagogical choice. Results highlight educators’ preferences for contextually relevant, hands-on learning experiences and the importance of ongoing support and professional community-building. While situated in a rural region, the findings have broader implications for professional development policy and practice across diverse educational settings. By explicitly examining how needs assessment findings were translated into professional development design decisions, this study contributes practice-based evidence for creating more equitable and context-responsive professional learning models.
