This study synthesizes the rapidly expanding evidence on how digital technologies reshape international trade, with a particular focus on small and medium-sized enterprises (SMEs). Guided by two research questions—(RQ1) How do digital tools influence the volume and composition of cross-border trade? and (RQ2) How do these effects vary by countries’ development level and firm size?—we conducted a PRISMA-compliant systematic literature review covering 2010–2024. Searches across eight major databases yielded 1857 records; after duplicate removal, title/abstract screening, full-text assessment, and Mixed Methods Appraisal Tool (MMAT 2018) quality checks, 86 peer-reviewed English-language studies were retained. Findings reveal three dominant technology clusters: (1) e-commerce platforms and cloud services, (2) IoT-enabled supply chain solutions, and (3) emerging AI analytics. E-commerce and cloud adoption consistently raise export intensity—doubling it for digitally mature SMEs—while AI applications are the fastest-growing research strand, particularly in East Asia and Northern Europe. However, benefits are uneven: firms in low-infrastructure settings face higher fixed digital costs, and cybersecurity and regulatory fragmentation remain pervasive obstacles. By integrating trade economics with development and SME internationalization studies, this review offers the first holistic framework that links national digital infrastructure and policy support to firm-level export performance. It shows that the trade-enhancing effects of digitalization are contingent on robust broadband penetration, affordable cloud access, and harmonized data-governance regimes. Policymakers should, therefore, prioritize inclusive digital-readiness programs, while business leaders should invest in complementary capabilities—data analytics, cyber-risk management, and cross-border e-logistics—to fully capture digital trade gains. This balanced perspective advances theory and practice on building resilient, equitable digital trade ecosystems. Full article

Background/Objectives: Effective teamwork is crucial for minimizing human error in healthcare settings. Medical teams, typically composed of physicians and nurses, supported by auxiliary professionals, achieve better outcomes when they possess strong collaborative competencies. High-quality teamwork is associated with fewer adverse events and complications and lower mortality rates. Based on this background, the objective of this study is to analyze the perception of non-technical skills and immediate learning outcomes in interprofessional simulation settings based on E-CRM items. Methods: A cross-sectional observational study was conducted involving participants from the official postgraduate Medicine and Nursing programs at the Catholic University of Murcia (UCAM) during the 2024–2025 academic year. Four interprofessional E-CRM simulation sessions were planned, involving randomly assigned groups with proportional representation of medical and nursing students. Teams worked consistently throughout the training and participated in clinical scenarios observed via video transmission by their peers. Post-scenario debriefings followed INACSL guidelines and employed the PEARLS method. Results: Findings indicate that 48.3% of participants had no difficulty identifying the team leader, while 51.7% reported minor difficulty. Role assignment posed moderate-to-high difficulty for 24.1% of respondents. Communication, situation awareness, and early help-seeking were generally managed with ease, though mobilizing resources remained a challenge for 27.5% of participants. Conclusions: This study supports the value of interprofessional education in developing essential competencies for handling urgent, emergency, and high-complexity clinical situations. Strengthening interdisciplinary collaboration contributes to safer, more effective patient care. Full article

Background: Residency training is a formative and rigorous experience, with burnout rates reported at 76%. Formal peer support groups have shown improvement in burnout among healthcare workers with anxiety and depression. Objective: Implement a peer support program for emergency medicine (EM) residents and characterize utilization of metrics by demographics, burnout rates of participants, and overall session impact. Methods: An IRB-approved, longitudinal, prospective cohort study of 73 EM and EM/Pediatrics residents post-graduate year (PGY) 1–5 from July 2021–June 2022 was performed. Resident peer leaders were trained using a novel curriculum to lead peer support groups. Residents were invited to participate in biweekly sessions, with optional pre- and post-session surveys measuring demographics, burnout, themes discussed, and how they felt after sessions (Patients’ Global Impression of Change scale). Results: There were 134 attendances over 20 sessions, averaging 6 residents per session. Of 73 total residents, 37 (50%) participated at least once. All levels of training were represented, with half being female, 20% underrepresented in medicine, and 14% LGBTQ+. Overall burnout rates were unchanged for first-time attendances (49%, n = 18) vs. recurrent (50%, n = 11). Females had higher burnout at both baseline (60%, n = 15) and recurrent sessions (69%, n = 13). Following sessions, 94% of participants reported feeling immediately better and 100% of leaders felt prepared leading peer support sessions. Conclusions: This study demonstrates that residents utilize peer support, with many returning more than once. Despite stable burnout rates, 94% of participants felt immediately better after the session, suggesting that peer support is a valuable resource for residents actively experiencing burnout.

The increasing penetration of renewable energy sources (RESs) has significantly altered the operational characteristics of modern power systems, resulting in reduced system inertia and fault current capacity. These developments introduce new challenges for maintaining frequency and voltage stability, particularly in low-inertia grids that are dominated by inverter-based resources (IBRs). This paper presents a hierarchical control framework that integrates synchronous condensers (SCs) and grid-forming (GFM) inverters through a leader–follower consensus control architecture to address these issues. In this approach, selected GFMs act as leaders to restore nominal voltage and frequency, while follower GFMs and SCs collaboratively share active and reactive power. The primary control employs droop-based regulation, and a distributed secondary layer enables proportional power sharing via peer-to-peer communication. A modified IEEE 14-bus test system is implemented in PSCAD to validate the proposed strategy under scenarios including load disturbances, reactive demand variations, and plug-and-play operations. Compared to conventional droop-based control, the proposed framework reduces frequency nadir by up to 0.3 Hz and voltage deviation by 1.1%, achieving optimised sharing indices. Results demonstrate that consensus-based coordination enhances dynamic stability and power-sharing fairness and supports the flexible integration of heterogeneous assets without requiring centralised control.

Background/Objectives: Rates of receiving opioid use disorder (OUD) treatment among adolescents and young adults (AYA) aged 16–25 are low. The current study qualitatively analyzed informants’ perspectives regarding the availability of, developmental considerations relevant to, and barriers associated with OUD treatment for AYA. Methods: Thirty key informants involved with OUD treatment in the northeastern United States completed individual, semi-structured interviews, including treatment providers (N = 11) and clinic leaders in programs that provide medication and psychosocial treatments for AYA with OUD (N = 10), as well as opioid-related policymakers (N = 6) and patient advocates (N = 3). Interviews were transcribed and independently double coded. Template-style thematic analysis methods were used and revealed seven themes. Results: The first theme highlighted limited treatment program availability for adolescents (aged < 18 years) with OUD. Four themes related to developmentally optimizing OUD treatment for AYA, describing the importance of caregiver involvement, AYA peer connections, wraparound services, and early intervention. Two themes described barriers to AYA OUD treatment, including stigma and knowledge gaps about medications for OUD as well as deficits in AYA’s access to basic resources (e.g., housing, food security) that prohibit effective participation in treatment. Conclusions: Results highlight concerns from systems-level key informants regarding gaps in OUD treatment options for youth under the age of 18 and a high need for OUD treatment that is developmentally tailored to AYA. Findings point toward potential modifications and additions to existing adult treatment programs to make OUD treatment more accessible, relevant, and engaging for AYA. Full article

Digital transformation is the process of using digital technologies for creating or modifying existing business processes and customer experience, leveraging cutting-edge technology to meet changing market needs. Disruptions like the COVID-19 pandemic, regional wars, and climate-driven natural disasters create consequential scenarios, e.g., global supply chain disruption creating further demand–supply mismatch for healthcare enterprises. According to KPMG’s 2021 Healthcare CEO Future Pulse, 97% of healthcare leaders reported that COVID-19 significantly accelerated the digital transformation agenda. Successful digital transformation initiatives, for example, digital twins for supply chains, augmented reality, the IoT, and cybersecurity technology initiatives implemented significantly enhanced resiliency in supply chain and manufacturing operations. However, according to another study conducted by Mckinsey & Company, 70% of digital transformation efforts for healthcare enterprises fail to meet their goals. Healthcare enterprises face unique challenges, such as complex regulatory environments, cultural resistance, workforce IT skills, and the need for data interoperability, which make digital transformation a challenging project. Therefore, this study explored potential barriers, enablers, disruption scenarios, and digital transformation use cases for healthcare enterprises. A structured literature review (SLR), followed by thematic content analysis, was conducted to inform the research objectives. A sample of sixty (n = 60) peer-reviewed journal articles were analyzed using research screening criteria and keywords aligned with research objectives. The key themes for digital transformation use cases identified in this study included information processing capability, workforce enablement, operational efficiency, and supply chain resilience. Collaborative leadership as a change agent, collaboration between information technology (IT) and operational technology (OT), and effective change management were identified as the key enablers for digital transformation of healthcare enterprises. This study will inform digital transformation leaders, researchers, and healthcare enterprises in the development of enterprise-level proactive strategies, business use cases, and roadmaps for digital transformation.

Work–family conflict (WFC) is a common issue faced by employees balancing work and family roles, but research exploring individual strategies to reduce its negative effects has been limited. Leaders’ positive humor is a mutually (leader–subordinates) amusing communication tool in the workplace. It has been shown to enhance peer relationships (coworker socializing (CWS)) and may serve as an effective coping mechanism that mitigates the adverse effects of workplace stress (work–family conflict). This study strives to examine the relationship between leaders’ positive humor (LPH) and work–family conflict (WFC), with coworker socializing (CWS) mediating this relationship and sensitivity to favorable interpersonal treatment (SFIT) moderating the relationship between leaders’ positive humor and coworker socializing in the tourism and hospitality industry. The research addresses a significant gap in previous studies by investigating these variables together. A total of 387 valid questionnaires were collected from employees of five-star hotels and tourism organizations in Egypt. This study employed PLS-SEM to analyze the data. The results showed that leaders’ positive humor negatively impacts work–family conflict, positively influences coworker socializing and that coworker socializing negatively affects work–family conflict. Additionally, coworker socializing mediated the association between leaders’ positive humor and work–family conflict, and sensitivity to favorable interpersonal treatment moderated the relationship between leaders’ positive humor and coworker socializing. This study provides theoretical and practical insights by validating the proposed model based on the Stimulus–Organism–Response (S-O-R) framework and the Conservation of Resources (COR) theory. Regarding practical implications, the study recommends leadership training on the effective use of humor to foster follower socialization and promote work–family balance. Full article

Herein, we address the peculiar lack of scientific reporting on odor potent chloroanisoles (CAs) in the built environment. We have searched and critically examined sources beyond peer-reviewed scientific journals, namely research conferences, parliamentary records, newspaper articles, and cartoons. We provide evidence that CAs evolved on a large scale in Swedish buildings in the early 1970s and evoked a typical sticky malodor that was attributed to mold and gave rise to the term “mold houses”. The term first appeared in Swedish newspapers in 1978, and the media attention increased rapidly. The malodorous “mold houses” reached the Swedish parliament and led to economic compensation for afflicted homeowners. The “mold houses” became “sick houses” as researchers, predominantly from Sweden, introduced and became world leaders on the “sick buildings syndrome” (SBS). Researchers became aware of the CAs but did not mention them in peer-reviewed articles, just as they did not mention a well-known source of the sticky malodor, namely, legacy preserved wood where CAs were formed through microbial methylation of toxic chlorophenols (CPs). Thus, the mold story from the early 1970s was maintained and prevented the malodorous CAs from becoming recognized as indicators of the presence of hazardous CPs. Our study is the first to report the impact of an indoor malodor, not only on a few people, but on society. Full article

Globally, many school systems face leadership shortages and challenges in building strong principal pipelines, making career intentions to pursue school leadership a critical area of study. This study examines how key features of educational leadership preparation programs (ELPPs) influence graduates’ intentions to become school leaders. Guided by Social Cognitive Career Theory (SCCT), we analyzed data from 2994 graduates across 51 U.S.-based ELPPs collected between 2016 and 2020, using structural equation modeling and estimation thinking to assess direct and mediated relationships among program features and career outcomes. Findings reveal that internship quality plays a pivotal role as both a direct predictor of career intentions and a mediator for other program features, including faculty quality, program rigor and relevance, and peer relationships. Faculty quality influences intentions primarily through rigor and relevance, while cohort participation contributes indirectly by fostering peer relationships and internship quality. Graduate attributes, including prior leadership experience, also shape career aspirations. This study extends SCCT by demonstrating how ELPP features shape candidates’ career intentions through interconnected pathways, offering insights that inform policy and program design aimed at strengthening pathways into school leadership.

The rise of Construction 4.0—driven by digitalisation, automation, and data-intensive technologies—is radically reshaping the construction industry. While its technological innovations are widely acknowledged, their implications for industrial relations remain underexplored. In this study, we conduct a systematic literature review (SLR) of 91 peer-reviewed articles published between 2010 and 2024, aiming to synthesise emerging knowledge on how Construction 4.0 is transforming workforce dynamics, employment models, and labour relations. Using NVivo software and an inductive thematic approach, we identify seven key themes: workforce transformation, the attraction of new generations and women, skill requirements and workforce development, supply chain and logistics optimisation, digital twin technology in project management, the emergence of new business models, and safety and risk assessment. Our findings highlight both opportunities—such as improved collaboration, skill diversification, and enhanced productivity—and challenges, including job displacement, digital ethics, and widening disparities between developed and developing countries. Recent studies from 2023 and 2024 underscore routine-biased changes in workforce structure, evolving project management practices through digital twins, and critical skill shortages within the sector. Furthermore, contemporary policy shifts and increasing labour tensions in some regions reveal deeper socio-economic implications of digital construction. This review contributes to a more holistic understanding of how technological innovation intersects with social systems in the built environment. The insights presented offer valuable guidance for policymakers, educators, and industry leaders seeking to navigate the evolving landscape of Construction 4.0. Full article

Outdoor education camps offer adventure programs to schools that deliver camp-based activities that challenge students in various ways. These camps provide students with an opportunity to learn in a natural environment, interact with their peers outside of the classroom, and participate in activities that challenge them both physically and mentally. Youth Adventure Camps also espouse a Christian ethos, Christian values, and spirituality, which are also key focuses. Prior research into outdoor education camps has examined the social, emotional, and physical benefits for students. In this study, data were collected through semi-structured interviews with five (n = 5) Christian Youth Adventure Camp (CYAC) staff to better understand their experiences and perceptions of their induction, ongoing training, strategies, and pedagogical approaches used to deliver the CYAC camp programs. Targeted observations of camp staff (N = 5) in action were also used to identify the intentional pedagogies they used to embed CYAC’s philosophy within their camp programs. This paper is part of a larger study, and its findings are focused on the perspectives of the camp leaders for two key reasons: First, we wanted to examine the intentional pedagogies of camp leaders, particularly those who were not qualified teachers; and second, our aim was to examine how these camp leaders included the values-based THRIVE philosophy in their day-to-day practice. Our findings show that, despite not being university-qualified educators, camp staff consistently employed intentional pedagogies that were effective in engaging students in opportunities to “thrive” in alignment with the philosophy underpinning their operations and to meet the goals of the school using their programs.

Internet-of-Things (IoT) devices are interconnected objects embedded with sensors and software, enabling data collection and exchange. These devices encompass a wide range of applications, from household appliances to industrial systems, designed to enhance connectivity and automation. In distributed IoT networks, achieving reliable decision-making necessitates robust consensus mechanisms that allow devices to agree on a shared state of truth without reliance on central authorities. Such mechanisms are critical for ensuring system resilience under diverse operational conditions. Recent research has identified three common limitations in existing consensus mechanisms for IoT environments: dependence on synchronised networks and clocks, reliance on centralised coordinators, and suboptimal performance. To address these challenges, this paper introduces a novel consensus mechanism called Randomised Asynchronous Consensus with Efficient Real-time Sampling (RACER). The RACER framework eliminates the need for synchronised networks and clocks by implementing the Sequenced Probabilistic Double Echo (SPDE) algorithm, which operates asynchronously without timing assumptions. Furthermore, to mitigate the reliance on centralised coordinators, RACER leverages the SPDE gossip protocol, which inherently requires no leaders, combined with a lightweight transaction ordering mechanism optimised for IoT sensor networks. Rather than using a blockchain for transaction ordering, we opted for an eventually consistent transaction ordering mechanism to specifically deal with high churn, asynchronous networks and to allow devices to independently and deterministically order transactions. To enhance the throughput of IoT networks, this paper also proposes a complementary algorithm, Peer-assisted Latency-Aware Traffic Optimisation (PLATO), designed to maximise efficiency within RACER-based systems. The combination of RACER and PLATO is able to maintain a throughput of above 600 mb/s on a 100-node network, significantly outperforming the compared consensus mechanisms in terms of network node size and performance.

Supplemental instruction (SI) is a well-established direct academic support model. SI leaders provide unique success strategies that benefit underserved and underprepared students in difficult courses. In this study, the novel application of SI strategies at the master’s level was explored. The subject university is a Hispanic Serving Institution in the southern United States, and a social science program was examined, focusing on 309 students. Key findings include an improvement in performance on a post-course evaluation compared with the pre-course instrument. This increase was present regardless of the number of SI sessions attended. An instructor effect was also identified. One specific instructor had a letter grade lower average course grade than their peers. For this instructor, pass rate and course grade were significantly improved by SI, and the more SI sessions attended, the greater the effect. For all other instructors, SI had a small improvement on pass rate and course grade, possibly the result of grade compression associated with graduate student evaluation. Full article

Students as Partners (SaP) programs have centered student voices since their inception. Student–faculty pedagogical partnerships are grounded in the notion that students have the expertise to contribute to faculty in preparing for, reflecting on, and revising teaching and learning practices in ways that are inclusive and responsive to all learners. This expertise is based in part on their lived experiences—both as students and as members of the student populations that SaP programs were intentionally created to help empower (e.g., first generation, low-income, BIPOC (Black, Indigenous, and people of Color) and others marginalized in higher education). These students, in dialogue with faculty, help to expose equity issues across classrooms. As SaP programs have proliferated in colleges and universities across the globe, the student partners’ role as social justice advocates in these programs have expanded too. This review explores the pedagogical partnership literature over the past 20 years, to establish the ways in which undergraduate students and post-bacs have flourished in leadership roles in SaP programs: (a) acting as leaders for social equity on campus, (b) serving as peer mentors to new student partners in existing programs, (c) co-creating new programs, and (d) publishing in the literature. This review reveals opportunities for new directions with peer mentorship in SaP programs through the role of lead student mentors who can help to scale up SaP programs, support the emotional labor involved in partnership work, and create pathways to future social justice leadership opportunities.
