Artificial intelligence (AI), as an advanced technological innovation, possesses considerable promise for improving energy efficiency and reducing emissions in industrial environments. Although AI plays a crucial role in industrial decarbonization, research reveals that many AI-dependent carbon reduction prospects remain untapped. This study examines the innovative correlation between the presentation styles of industrial AI recommendations and the trust that carbon management technicians have in AI from an ergonomic standpoint. This study combines the Stimulus-Organism-Response theory with the Elaboration Likelihood Model. The findings from three experiments reveal that precise and informative styles of AI recommendations enhance trust among technicians. Furthermore, we present mediating evidence with advanced eye-tracking devices, illustrating that cognitive effort strengthens the positive effect of precise abatement recommendations on trust toward AI (Study 2). Further research indicates that the positive effect of precise or informative AI-generated abatement recommendations on trust is amplified when technicians experience more positive emotions (Study 3). Overall, this study identifies distinct mechanisms through which the presentation styles of industrial AI recommendations can affect technicians' trust. These findings hold practical significance for developers of industrial AI systems and carbon management technicians who strategically utilize AI-generated information.

Objective
To compare visual versus haptic cueing modalities in modulating gait variability temporal structure using white noise, pink noise, and invariant interval patterns.
Background
Healthy human movement exhibits "pink noise" variability, representing optimal balance between stability and adaptability. Aging and pathology disrupt this pattern. While external cueing can help restore healthy patterns, visual and auditory approaches limit environmental awareness.
Method
Ten healthy young adults completed 12-min walking trials for each cueing condition across two counterbalanced sessions. Gait variability was quantified through Detrended Fluctuation Analysis (α) of inter-stride intervals. Synchronization accuracy between heel strikes and cues was measured as asynchrony. Usability was assessed using a modified System Usability Scale.
Results
Bayesian multilevel modeling showed noise condition significantly influenced α values, with white noise and invariant conditions reducing α values compared to control and pink noise conditions. Asynchrony values were not influenced by cueing type, modality, or session. Haptic cueing was strongly preferred over visual for frequent use (P = 0.985), reduced awkwardness (P = 0.996), and increased confidence (P = 0.996).
Conclusion
Both modalities effectively modulated gait variability, with no differences in synchronization performance. However, haptic cueing received significantly higher usability ratings in key areas.
Application
Haptic cueing offers an effective alternative to visual cueing for gait rehabilitation, providing similar effectiveness while maintaining environmental awareness and better user experience, with potential applications through wearable technologies.

The Work-Oriented Training Path (WOTP) in Quebec, Canada, is a dual vocational training program that offers students with learning difficulties supervised traineeships. Teachers play a pivotal role in managing students' occupational health and safety (OHS), yet must do so under tight time constraints, limited institutional guidance and highly diverse student profiles. Building on an activity-centered ergonomics and capabilities framework, this multiple-case study explores how gender, disabilities, and work determinants shape OHS management within the WOTP, emphasizing their implications for social sustainability. Twenty-seven semi-structured interviews were conducted with 15 WOTP teachers; 497 narrated anecdotes, which are units of speech when teachers' talk about students, were thematically analyzed to capture everyday mechanisms that expand or restrict safe participation in traineeship. The findings highlight challenges stemming from power dynamics between teachers, parents, and employers, which influence the operational leeway available for teachers to implement OHS prevention. Their work organization, conditions and tools also expand or restrict their capability to have an equitable approach. Additionally, the analysis reveals disparities in traineeship placement opportunities and OHS prevention, particularly concerning students’ gender identity and disabilities. Key factors influencing traineeship placements and OHS practices included students' communication skills, perceived autonomy, and suitability of behavior compared to social norms. Students with disabilities are frequently assigned repetitive tasks, increasing exposure to hazards that remain under-recognized. These results underscore the critical need for inclusive OHS prevention, fostering a more socially sustainable approach within vocational training programs.

High voltage overhead powerline work is physically demanding and exposes workers to a high risk of work-related musculoskeletal disorders (WRMSDs). This study investigated the effectiveness of interventions to reduce the risk of WRMSDs in powerline operators. Sixteen operators from Thailand who regularly used mobile elevating work platforms participated in the study. Following a task evaluation, an ergonomics improvement programme was implemented which involved engineering-design changes (e.g. purpose designed handling devices) and ergonomics training (e.g. techniques to reduce physically demanding postures). Pre- and post-intervention measures involved a musculoskeletal health survey, Rapid Entire Body Assessment (REBA) and the assessment of WRMSD risk levels (risk matrix). The ergonomics improvement programme led to changes in postures and working practices, and a reduction in WRMSD symptom reporting and WRMSD risk classifications when compared to pre-intervention measures. Following the intervention, musculoskeletal discomfort decreased by 25 % in the hands and wrists, 12.5 % in the shoulders, arms, and lower back, and 6.3 % in the neck, upper back, hips, knees, feet, and ankles. There was a significant shift to lower REBA scores and risk matrix classifications changed from high to medium risk. The implementation of engineering-designed changes combined with ergonomics training was effective in reducing the short-term risks associated with WRMSDs in high voltage overhead powerline workers. Further work is needed to determine the long-term effects of these interventions on the occupational health of powerline workers, along with strategies for addressing other risk factors (e.g. psychosocial, work organisation) known to impact on the incidence of WRMSDs.

Occupational exoskeletons are emerging as a promising solution to reduce work-related musculoskeletal disorders (MSDs) across various industries. Upper-limb exoskeletons are particularly relevant, given the high prevalence of MSDs associated with repetitive arm motions and overhead tasks. However, evaluating the effectiveness of these devices requires careful analysis of the specific technologies and kinematic designs they incorporate to ensure their safe and effective integration. This paper presents a detailed technological review and analysis of the existing literature, focusing on the diversity of technologies and the need for more comprehensive studies addressing challenges in both laboratory and real-world settings. This study particularly highlights the necessity of assessments that account for the unique characteristics of different exoskeleton technologies, rather than generalizing across them. It also emphasize the need to examine not only reductions in muscle activity but also the potential for overlooked side effects, long-term impacts, and adaptations across different task types. These factors are crucial, as upper-limb exoskeletons are planned to be deployed for prolonged use in complex industrial environments.

Prevention through Design (PtD) mitigates risks by integrating safety into early design stages, thereby enhancing building lifecycle safety. Despite its recognized importance, PtD remains insufficiently integrated into Architecture, Engineering, and Construction (AEC) education. This study examines discipline-specific barriers and motivators influencing student engagement with PtD, which had not been documented previously. A survey of 178 AEC students revealed low overall familiarity with PtD (11–15 %) and significant differences among disciplines in learning readiness and preferences. Architecture students exhibited the lowest worker safety awareness (56.7 %) and considered it less central to their design roles. Engineering students demonstrated moderate recognition of their worker safety responsibilities (77 %), while construction students, despite acknowledging the highest responsibility (92 %), expressed the least enthusiasm for formal PtD education. PtD's life-saving potential emerged as the primary motivator across all AEC disciplines. Secondary motivators varied by discipline. Construction students preferred learning PtD through tangible outcomes such as cost savings and schedule efficiencies, while architecture and engineering students were motivated by technology integration and career enhancement. Students showed an aversion to traditional reading and writing approaches, indicating a misalignment between conventional instruction and student preferences. Learning preferences differed by discipline. Architecture students favored visual learning strategies, while engineering and construction students preferred kinesthetic methods. These insights highlight the need for technology-enabled, case-based learning strategies that leverage disciplinary motivators and align with preferred learning modalities. Adopting these approaches is critical for equipping future AEC professionals with essential PtD competencies and advancing safer design.

Workforce agility is critical in the healthcare sector to navigate uncertainties and sudden changes in clinical environments, contributing significantly to job performance. However, specific factors contributing to agility in healthcare remain mainly unknown. This study investigates the impact of information technology ambidexterity and human resource practices on workforce agility. One hundred thirty-eight medical professionals from Peru participated in the study. Partial least squares structural equation modeling (PLS-SEM) was employed. The results indicate that information technology ambidexterity and human resource practices positively affect workforce agility. Furthermore, workforce agility mediates the effects of information technology ambidexterity and human resource practices on job performance. These results also suggest that healthcare organizations in Peru should not only invest in information technology ambidexterity and enhance human resource practices but also actively foster workforce agility to positively impact medical professionals' job performance.

The weakness of cognitive control in young novice drivers may be a potential mechanism leading to road traffic injuries and fatalities among this group. While previous research has demonstrated the association of cognitive control with risky driving, the mechanism of cognitive control in driving and the role of eye movements in this relationship remain unclear. Therefore, the present study aims to clarify the theoretical framework of the relationships between two typical cognitive control capacities, namely working memory and response inhibition, with driving performance and eye movements. The goals are to determine when working memory capacity (WMC) and response inhibition ability (RIA) influence driving performance, to explore the possible interactive moderating effect between WMC and RIA, and to reveal the mediating effect of eye movements in the relationship between cognitive control and driving performance. During the experimental process, participants completed two WMC tasks (visuospatial working memory (VSWM), and verbal working memory (VWM)), an RIA task (cued go/no-go), and a simulated driving task (including car-following, pedestrian-crossing, etc.). Experimental data were obtained from 49 young Chinese novice drivers. The results showed that WMC and RIA significantly predicted overall driving performance, and stronger cognitive control leading to better driving performance in terms of the percentage of time spent over the speed limit (speeding), the standard deviation of the lateral position from the central line (SDLP), driving performance score, accident frequency, minimum time to collision (TTC), braking reaction time (BRT), and time to meet pedestrian (TMP). Moreover, WMC was found to moderate the relationship between RIA and driving performance. Specifically, WMC significantly predicted the driving performance score, accident frequency, and TMP for drivers with lower inhibitory control, and the WMC prediction of BRT was more pronounced for inattentive drivers. WMC was also found to predict eye movements, including vigilance (horizontal and vertical gaze variability) and effort level (pupil dilation). The relationship between WMC and driving performance was also found to be mediated by eye movements. Specifically, vertical gaze variability mediated the effects of VSWM on the driving performance score, accident frequency, and BRT, as well as the effects of VWM on BRT. Furthermore, pupil dilation mediated the effects of VWM on BRT. This study also discusses the potential mechanism of risky driving from the cognitive perspective, and improves the theoretical framework of “working memory–eye movement–driving performance.” Thus, this research is of theoretical and practical significance for driver safety training and risky driving intervention.

Exoskeletons offer significant potential to enhance mobility and support independent living in older adults. However, their widespread adoption is hindered by a limited understanding of the diverse user needs and design requirements. To address this gap, we conducted a two-stage human-centered participatory study to identify user needs, preferences, and design requirements for soft exoskeletons design and evaluation. Stage 1 comprised six co-design workshops with older adults with mobility challenges and their family caregivers (n = 14), focusing on lived experiences, physio-psychosocial needs, and design expectations. Stage 2 involved laboratory-based assessments with 157 older adults to collect behavioral, functional, and biomechanical parameters relevant to exoskeleton performance requirements. The study identified four core physio-psychosocial needs, 13 design requirements, and nine objective performance benchmarks. Key priorities include facilitating daily task performance and mobility to foster independence and prevent injury; ensuring comfort, personalization, and durability; supporting competence and self-esteem through ease of use, aesthetic design, and affordability; promoting social connectedness and inclusion; and upholding ethical and moral integrity through accessibility, data security, and transparency. The nine evaluation benchmarks encompass biomechanical, functional, and behavioral parameters, including step length, stride length, handgrip strength, knee maximal voluntary contraction at multiple angles, walking speed, chair stand performance, and Short Physical Performance Battery scores. The finding offers a practical, evidence-based framework for aligning soft exoskeletons with the complex physical, psychological, and social needs of older adults, thereby promoting usability, acceptance, and adoption in aging societies.

The increasing shortage of qualified gerontological nurses poses a significant challenge to the healthcare system. To address this issue, an AI-enabled immersive virtual reality (VR) system was previously developed to enhance gerontological nursing training in senior care facilities. In this study, we focus on systematically evaluating user acceptance of this AI-enabled VR-based training system using an extended Technology Acceptance Model (TAM). The evaluation framework incorporates both classical TAM constructs and additional context-specific factors such as personal innovativeness and presence. Data collected from 45 gerontological nurses (41 valid records) were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). Results show that perceived usefulness significantly impacts intention to use, as well as perceived enjoyment of the system; personal innovativeness significantly influences perceived ease of use, enjoyment, and intention to use; and intention to use positively influences intention to purchase if commercialized. These findings offer new insights into the adoption of immersive AI-VR tools in healthcare education and extend existing acceptance modeling approaches in the field of nursing training.
