Three-wheelers (3Ws—autos or auto-rickshaws) occupy a unique yet salient and substantive position within the context of India’s urban mobility. They provide critical first-and-last-mile connectivity, fill public transit coverage gaps, boost local and urban agglomeration economies, and are a major income source for millions. Their value and utility are especially pronounced in rapidly emerging Tier-II cities such as Amritsar. The city’s 7500-strong diesel 3W (d3W) fleet is the backbone of its transportation network but also contributes to air pollution. Though Amritsar’s favorable policies to transition the d3W fleet to electric (e3W) have reduced purchase costs by 40–60%, barriers remain. This study investigates the influence of the e3W user experience through a first-of-a-kind three-day pilot trial for ~300 d3W drivers. By leveraging a pre- and post-intervention framework combining surveys and trip diaries, this study evaluated how direct exposure influences adoption intentions, perceptions, and the social dynamics underpinning decision-making. In total, ~6% of participants switched to e3Ws following the trial, and there was a 20% drop in “don’t know” answers regarding charging duration and range. The results show non-random and meaningful shifts in attitudes, a greater awareness of range and charging times, improved views on charging convenience and vehicle safety, and air quality benefits.

Bedside echocardiography stands as a cornerstone diagnostic tool in internal medicine, offering rapid, real-time evaluation of cardiac structure and function across a wide spectrum of acute and chronic conditions. Its application, particularly when combined with lung and inferior vena cava (IVC) ultrasound, significantly enhances diagnostic accuracy for fluid balance assessment, dyspnea, and hypotensive states, guiding timely therapeutic decisions. Focused cardiac ultrasound (FoCUS) enables internists to assess left ventricular function, right atrial pressure, valvular abnormalities, and pericardial effusion, facilitating differentiation between cardiac and non-cardiac causes of symptoms such as dyspnea, chest pain, and hemodynamic instability. While operator-dependent, echocardiography can be effectively integrated into internal medicine practice through structured training programs that combine theoretical knowledge with supervised hands-on experience. This integration enhances clinical decision-making, optimizes patient management, and reduces the need for immediate specialist consultation. Widespread adoption of focused ultrasound techniques in internal medicine wards promises not only improved patient outcomes but also more efficient utilization of healthcare resources. Continued education and institutional support are fundamental to embedding echocardiography into routine care, ensuring internists are equipped to leverage this powerful bedside modality. This narrative review aims to underscore the transformative impact of bedside echocardiography in internal medicine, demonstrating its capacity, when combined with lung and IVC ultrasound, to optimize diagnostic pathways and treatment decisions across diverse acute and chronic settings.

This empirical paper explores South African preservice accounting teachers’ perceptions of ICT integration in secondary schools’ accounting curriculum practices. Since 2020, curriculum practices have been characterised by disruptions to traditional teaching and learning methods, including those brought on by the COVID-19 pandemic. Curriculum practices in accounting were not unnoticed. These sparked discussions about pedagogical changes, academic continuity, and the future of accounting curriculum practices. The theoretical framework used to guide the research process is connectivism. The theory is about forming connections between people and technology and teaching and learning in a connectivist learning environment. Connectivism promotes a lifelong learning perspective by training teachers and students to adapt to a fast-changing environment. An interpretive paradigm underpins this qualitative research paper. The data were collected from semi-structured interviews with five preservice accounting teachers about how they navigated pedagogy while switching to digital curriculum practices. Thematic analysis was used. The findings revealed that preservice accounting teachers faced challenges in ICT integration during school-based training, including limited resources, inadequate infrastructure, and insufficient hands-on training. While ICT tools enhanced learner engagement, barriers such as low digital skills and a lack of technical support hindered effective use. Participants highlighted a disconnect between theoretical training and classroom practice, prompting self-directed learning to bridge skill gaps. The study underscores the need for teacher education programs to provide practical, immersive ICT training to equip future educators for technology-driven classrooms. Full article

Background: Infantile colic affects up to 40% of otherwise healthy infants and can severely distress caregivers. Manual therapies are increasingly employed as non-pharmacological options, yet their effectiveness and safety remain uncertain. Methods: A scoping review was conducted in accordance with Joanna Briggs Institute methodology and reported following PRISMA-ScR. Five databases (MEDLINE, CENTRAL, Scopus, PEDro, Web of Science) were searched from December 2024 to May 2025 without restrictions at the search stage; however, only English-language randomised controlled trials published from 2012 onwards were included at the eligibility stage to ensure consistency and focus on the most recent body of evidence. Randomised controlled trials (RCTs) evaluating hands-on interventions for infants ≤ 6 months with colic were eligible. Two reviewers independently screened records, charted data, and grouped outcomes narratively. Results: Seven RCTs investigated abdominal massage, paediatric Tuina, craniosacral therapy, chiropractic manipulation, osteopathic light touch, reflexology, and acupressure. Five trials reported statistically or clinically significant reductions in daily crying (0.6–6.6 h) compared with usual care or sham. Three studies also documented meaningful gains in sleep duration (1.1–2.8 h). Parent-reported satisfaction improved in most interventions. No serious adverse events were recorded, although safety monitoring was inconsistently reported. Substantial heterogeneity in diagnostic criteria, outcome measures, and intervention dose precluded meta-analysis. Conclusions: Low-force manual therapies may offer modest short-term relief for colicky infants and improve parental experience, with an apparently favourable safety profile. However, methodological variability and small sample sizes limit certainty. Standardised protocols, objective outcome measures, and robust adverse-event surveillance are priorities for future research. Full article

Mango production plays a vital role in rural livelihoods in Mozambique, yet post-harvest losses remain high, ranging from 25% to over 50%, due to inadequate preservation methods. Improved solar drying technologies offer a sustainable solution by extending shelf life and enhancing product quality. However, their adoption among smallholder mango farmers remains limited. This study investigates the key barriers and drivers influencing the uptake of these technologies in three districts of Inhambane Province, through a combination of literature review and semi-structured interviews. Major barriers include limited technical knowledge, high upfront costs, poor market access, and limited institutional support. Field data show that over 80% of farmers are unaware of improved fruit drying techniques, and fewer than 5% have received any training. While the literature emphasizes environmental sustainability and policy support, field interviews highlight a stronger interest in practical enablers, such as affordable systems, hands-on training, and income-generating potential. The study calls for a multisectoral approach, involving financial support, capacity-building, and strengthened extension services to promote adoption. Scaling solar drying technologies can significantly reduce post-harvest losses and strengthen the mango value chain, contributing to food security and rural development in Mozambique. Full article

The growing frequency of cybersecurity incidents, coupled with the increasing significance of blockchain technology in today’s digital landscape, highlights the urgent need for enriched, hands-on educational programs within Computer Science and Engineering curricula. While core blockchain curricula typically cover consensus protocols, smart contracts, and cryptographic foundations, more advanced topics like InterPlanetary File System (IPFS) and oracles pose teaching challenges due to their complexity and reliance on broader system knowledge. Despite this, their critical role in decentralized applications (dApps) justifies their inclusion at least through practical use cases. The integration of the IPFS protocol with Distributed Ledger Technologies (DLTs) can enable pure decentralized storage subsystems for dApps, avoiding single points of failure and ensuring data integrity and security. At the same time, as an external source of information, oracles are required to ensure data correctness while managing IPFS data. Despite the potential use of such components in real use cases, the current literature lacks detailed oracle implementations designed to interact with the IPFS protocol. To tackle such an issue, this article presents two open-source use cases that integrate smart contracts, an oracle and an IPFS-based storage subsystem that will allow future professors, students, researchers and developers to learn and experiment with advanced dApps and DLTs.

This study investigates the causes of mathematics anxiety, its effect on mathematical performance, and the influence of field placement among preservice teachers enrolled in a field-based elementary mathematics methods course. To investigate this, the study utilized four tools: the Abbreviated Mathematics Anxiety Rating Scale (A-MARS), concept maps, Praxis Core test score, and questionnaires. The quantitative analysis indicates a negative correlation between anxiety and math performance. The analysis of concept maps and questionnaires indicate that key contributors to math anxiety include pop-up quizzes, tests, exams, memorization of mathematical ideas, and past negative experiences with school mathematics. The qualitative data analysis revealed that reduced mathematics anxiety during field placements was primarily due to practical teaching experience, constructive feedback, positive student interactions, and opportunities for observation and reflection. Understanding the root causes of mathematics anxiety is essential for supporting preservice teachers and improving their teaching effectiveness. Additionally, field placements play a crucial role in reducing math anxiety by providing hands-on teaching experience and building confidence. It is important to alleviate math anxiety in preservice teachers to have a more positive impact on their future students. Full article

The rapid integration of artificial intelligence (AI), particularly generative AI (Gen-AI), into higher education presents a critical challenge: preparing students for the complex ethical dilemmas inherent in AI-driven research and practice. Current AI ethics education, however, often remains fragmented, overly theoretical, and disconnected from practical application, leaving a significant gap between knowing ethical principles and acting upon them. To address this pressing issue, this study proposes and validates a full-cycle AI ethics education system designed to bridge this gap. The system integrates three core components: (1) an updated four-dimensional ethics framework focused on Gen-AI challenges (research review, data privacy, algorithmic fairness, intellectual property); (2) a “cognition-behavior” dual-loop training mechanism that combines theoretical learning with hands-on, simulated practice; and (3) a full life-cycle education platform featuring tools like virtual laboratories to support experiential learning. A mixed-methods study with 360 students and 20 instructors demonstrated the system’s effectiveness, showing significant improvement in students’ ethical knowledge, a large effect size in enhancing ethical decision-making capabilities, and high user satisfaction. These findings validate a scalable model for AI ethics education that moves beyond passive instruction toward active, situated learning, offering a robust solution for higher education institutions to cultivate ethical responsibility in the age of Gen-AI.

Due to rapid technical advancements and increasing cost-effectiveness, the potential application of next-generation sequencing (NGS) in newborn screening (NBS) has raised great interest worldwide. Genomic NBS offers the possibility to improve current NBS programs when applied as follow-up tier, and, as first-tier, allows for inclusion of conditions lacking a detectable biomarker for conventional NBS. Obtaining enough high-quality DNA from typically limited dried blood spot (DBS) material to meet NGS requirements can be challenging. Selecting a DNA isolation method for genomic NBS requires balancing technical performance and laboratory feasibility with optimal cost-effectiveness. Ten DNA isolation protocols, including two column-based, five lysis-based, and three semi-automated magnetic bead-based protocols, were evaluated on technical outcomes and performance in targeted amplicon sequencing. Additionally, estimated costs, hands-on time, turnaround time, scalability, and plastic footprint were assessed. Although technical outcomes, including yield, purity, and molecular weight, differed between methods, qualitative results in amplicon sequencing, as defined by read output, mapping, and coverage depth, were found sufficient and comparable for various protocols. In conclusion, both technical requirements and operational parameters are crucial when selecting a DNA isolation protocol and will depend on the NGS application as well as the NBS approach, as either first-tier or follow-up tier.
