Published: February 2025

A high-current, long-pulsed beam operation without beam loss was demonstrated at the Superconducting rf Test Facility (STF) of the High Energy Accelerator Research Organization. The primary purpose of the STF was to validate the superconducting radio-frequency (rf) acceleration technology for the International Linear Collider (ILC) using accelerator components in line with the ILC design. Thus, the most critical objective of STF was to perform beam operations with a pulse length (726−μsec) and current (5.8 mA) equal to those of the ILC. Severe radiation caused by beam loss hinders stable beam operation. In a 100−μsec pulsed beam operation, a gradient drop in the accelerating cavities owing to beam loading causes beam loss. This beam loading was suppressed by imposing an additional driving power as feedforward control (BeamFF) to compensate for the gradient drop. BeamFF can completely suppress the gradient variation from a flattop to a 0.4% level with an amplitude stability of 0.3%–0.4%. Based on the knowledge obtained in the 100−μsec beam operation, we achieved a stable 726−μsec, 5.8-mA beam operation, and a beam power of 5.6 kW. The maximum energy variation of the pulsed beam was 1.5%. This value is significantly less than the threshold of 4%, which causes beam loss. We thus verified the stable beam acceleration technology for the ILC at the STF.

Environmental, social and governance (ESG) disclosure quality in developing countries: evidence from the ASEAN region
Authors: Abu Afifa Malik , Nguyen Nha Minh , Bui Duong Van 
Published: February 2025

Purpose
This study aims to investigate the nexus among environmental, social and governance disclosure quality (ESGDQ), corporate governance (COG) and corporate social responsibility strategy (CSRS) in the context of ASEAN, a developing market. Furthermore, carbon emission (CAE) has been considered as a moderation component for the CSRS–ESGDQ link.

Design/methodology/approach
With strict selection criteria, five countries in the ASEAN region (ASEAN-5) were selected as the research sample frame, including Vietnam, Thailand, Malaysia, Indonesia and the Philippines. Using the Thomson Reuters Eikon database, the initial sample included 4,735 listed companies in ASEAN-5. After a rigorous screening process, there were a total of 683 companies in the final sample with the 2018–2022 intervals.

Findings
By using maximum likelihood structural equation modeling, the finding indicates that COG and CSRS have a favorable effect on ESGDQ in the ASEAN-5 context. Furthermore, CAE plays an outstanding moderation role in the CSRS–ESGDQ link. The fundamental accounting standards are also identified as having an impact on ESGDQ.

Practical implications
The research points up the dominant role of internal components (i.e. COG, CSRS and CAE) and government factor (i.e. fundamental accounting standards) for the sustainable value (i.e. ESGDQ) of firms in ASEAN-5, a developing market. Thus, firm headers should inspect the performance of these internal components at a crucial interval to enhance their environmental, social and governance (ESG) behaviors and make them more sustainable. Furthermore, governments in ASEAN-5 should pay attention to developing areas that have low CAE and have a favorable influence on national sustainable development goals.

Social implications
The findings of the research provide some social implications by pointing up important factors influencing sustainability practices, and understanding how ESG practices can be improved in developing countries.

Originality/value
The research enlarges ESG documentation by specifying the influences of internal components and government factor, as well as providing actual proof from developing regions. In addition, this study identifies the effectiveness of CAE as well as its moderating role in this context.
A cross-generational learning in organizations: the case of four civil engineering firms
Authors: Heo Dongcheol , Smuttrasen Kanlayakorn 
Published: February 2025

Purpose
This study explores how cross-generational learning is implemented and conditioned in organizations and the role of management in this process.

Design/methodology/approach
This is a multiple case study research.

Findings
The study identified three features of cross-generational learning (CGL): 1. CGL is a role-based practice where participants serve as either knowledge givers or receivers. 2. Knowledge transferred between generations, especially from the senior to the junior generation, is embedded in the organization’s work practices and bounded by path dependence. 3. Appropriate management commitment to CGL can mitigate the power and path dependence of the seniors, primarily through the active engagement of junior employees and the design of practices for equal knowledge co-creation.

Research limitations/implications
The study is exploratory and needs further examination with more cases and populations.

Practical implications
First, management can cultivate organizational learning by assigning appropriate roles to each generation. Senior and junior employees possess different knowledge and capability strengths. Second, management should promote a culture of psychological safety. The effectiveness of CGL largely depends on the status and authority of the knowledge giver, which may be influenced by their past experiences. Third, management can leverage CGL to enhance corporate innovation by acknowledging that past experiences play a crucial role in its development.

Originality/value
The study shows effective cross-generational learning can be conducted by assigning appropriate roles for each generation in their work practices. It also reveals that companies can help facilitate better learning among generations by designing and implementing knowledge management processes and systems that encourage juniors’ participation and contribution to product development and business operations. Last but not least, this study proves that managerial understanding and support can balance the influence of senior and junior generations by mitigating excessive power and curbing the influence of path dependency from one side.

Authors: Saha Shagnik , Saini Gordhan Kumar 
Published: February 2025

PurposeTo study the mediating effect of resilience and the moderating effect of gender on the association between satisfaction with life and self-efficacy.Design/methodology/approachParticipants were 211 HR professionals; mediation and moderation hypotheses were tested using PROCESS macro.FindingsResults revealed a significant association between satisfaction with life, self-efficacy and dimensions of resilience. The mediating effect was significant for three dimensions of resilience: positive acceptance, personal competence and trust in one’s instincts. Gender moderated the relationship between satisfaction with life and self-efficacy through positive acceptance and positive competence but not trust in one’s instincts.Originality/valueMost literature examines satisfaction with life as an outcome measure despite existing calls and alternate theoretical frameworks. This study considers satisfaction with life as a predictor of self-efficacy and resilience. Linkages with theoretical frameworks and implications are discussed.

Published: February 2025

PurposeThis study analyses the direct and indirect impacts of risks on the service-oriented construction supply chain and its resilience during disruptions.Design/methodology/approachWe utilised the service-dominant logic, contingency and information processing theories to identify service-oriented construction supply chain characteristics and risk behaviours during turbulent times.FindingsOur analysis of 285 construction companies with a strong service orientation revealed that the proposed risk model explains a 33.6% variance in supplier performance, 46.4% operational performance, 47.1% customer satisfaction and 46.5% financial performance. Our findings highlight the importance of effectively monitoring risks in service-oriented construction supply chains and examining complex networks in which risk variables impact construction supply chain performance.Research limitations/implicationsThis study examines the influence mechanisms between risks and actors’ performance in construction supply chains, taking a service-oriented perspective.Originality/valuePrevious studies emphasise the risks that construction companies encounter from disruptions, such as maintaining operations and enhancing performance. Nevertheless, the research still needs to establish the transmission mechanism of the simultaneous impact (direct and indirect) of all forms of risk on supply chain performance.
Campus environments and mental restoration: eye-tracking evidence from dynamic stimuli
Authors: Wang Mengrui , Zhang Shuting , Zhou Xiang 
Published: February 2025

PurposeUnderstanding the restorative potential of built environments is essential for promoting mental well-being. However, existing studies often rely on static image-based methods, which are inherently limited in capturing the temporal and spatial dynamics of environmental perception. These methods frequently introduce biases, such as selective framing and abrupt transitions, failing to reflect natural viewing behavior. Addressing these limitations, this study investigates the restorative qualities of campus environments using dynamic VR stimuli and eye-tracking technology. By providing continuous temporal and spatial information, dynamic VR stimuli offer a more immersive and ecologically valid approach to understanding how specific environmental features contribute to psychological restoration.Design/methodology/approachThis study investigates the restorative qualities of campus environments using VR eye-tracking technology and dynamic stimuli. Campus environments were filmed through walking sequences and paired with PRS audio prompts. About 40 university students participated in the experiment, with eye-tracking data processed using computer vision-based semantic segmentation and the concept of relative areas of interest, followed by correlation analysis with restorative quality scores.FindingsThe results revealed that natural elements such as “sky,” “tree,” “waterscape” and “landscape corridor” were significantly positively correlated with the being-away and fascination dimensions, indicating their role in capturing attention and supporting psychological recovery. Conversely, architectural elements like “architectural corridor” and “building facade” were negatively correlated with the extent dimension, while “architectural open space” positively correlated, enhancing spatial perception and exploration.Originality/valueThese findings underscore the importance of natural elements and open spaces in built environments while also revealing the complex influence of architectural features. The study provides valuable insights for optimizing campus design to support students’ mental health and well-being.

Published: February 2025

PurposeReinforced autoclaved aerated concrete (RAAC) panels have been extensively used in the UK since the 1960s as structural roofs, floors and walls. The lack of a longitudinal, objective, consistent defect data capture process has led to inaccurate, invalid and incomplete RAAC data, which limits the ability to survey RAAC within buildings and monitor performance. Therefore, an accurate, complete and valid digital data capture process is needed to facilitate better RAAC performance and defect monitoring. This paper presents the development of an artificial intelligence (AI)-driven RAAC crack defect capture tool for improving the quality of RAAC survey data.Design/methodology/approachRAAC crack defect image data were collected, curated and trained. A deep learning approach was employed to train RAAC surveyed defects (cracks) images from two hospitals. This approach mitigated unavoidable occlusions/obstructions and unintended “foreign” objects and textures.FindingsAn automatic RAAC crack identification tool has been developed to be integrated into RAAC survey processes via an executable code. The executable code categorises RAAC survey images into “crack” or “non-crack” and can provide longitudinal graphical evidence of changes in the RAAC over time.Originality/valueThis paper identifies the role of AI in addressing the intrinsic defects data capture issues for RAAC and extends current debates on data-driven solutions for defect capture and monitoring.

Published: February 2025

Purpose
This study aims to investigate, through employees’ perceptions in Greece’s private sector, the relationship between the minimum wage and employee well-being, job satisfaction and work-life balance.

Design/methodology/approach
A structured questionnaire was used consisting of four sections: employees’ personal characteristics, employee well-being, job satisfaction and work-life balance. Due to its normal distribution, correlations, T-test and simple linear regression models were executed to examine the relationships between the variables.

Findings
The main findings were: a) the wage had a significant relationship with job satisfaction and employees’ well-being, b) there is no strong statistical significance between work-life balance and wages, c) the wage was found to be a significant predictor of employees’ well-being and work life balance, and d) there were statistically significant differences between the group of employees who received the minimum wage and the group of employees who received higher wages in terms of employees’ well-being.

Originality/value
The originality of this study is that it combines a purely financial concept, such as the minimum wage, with specific elements of organizational behaviour, such as employee well-being. A better understanding of this relationship will enable companies to increase employee productivity through their willing cooperation.

Research on optimization and evaluation method of heavy-haul train cyclic braking manipulation
Authors: He Wen , Chang Chongyi , Li Lan , Song Yupan 
Published: February 2025

PurposeThe study aims to build a high-precision longitudinal dynamics model for heavy-haul trains and validate it with line test data, present an optimization method for multi-stage cyclic brakes based on the model and conduct a multi-objective detailed evaluation of the driver’s manipulation during cyclic braking.Design/methodology/approachThe high-precision longitudinal train dynamics model was established and verified by the cyclic braking test data of the 20,000 t heavy-haul combination train on the long and steep downgrade. Then the genetic algorithm is employed for optimization subsequent to decoupling multiple cyclic braking procedures, with due consideration of driver operation rules. For evaluation, key manipulation assessments in the scenario are prioritized, supplemented by multi-objective evaluation requirements, and the computational model is employed for detailed evaluation analysis.FindingsBased on the model, experimental data reveal that the probability of longitudinal force error being less than 64.6 kN is approximately 68%, 95% for less than 129.2 kN and 99.7% for less than 193.8 kN. Upon optimizing manipulations during the cyclic braking, the maximum reduction in coupler force spans from 21% ∼ 23.9%. And the evaluation scores imply that a proper elevation of the releasing speed favors safety. A high electric braking force, although beneficial to some extent for energy-saving, is detrimental to reducing coupler force.Originality/valueThe results will provide a theoretical basis and practical guidance for further ensuring the safety and energy-efficient operation of heavy haul trains on long downhill sections and improving the operational quality of heavy-haul trains.
Estimation of Species Abundance Based on the Number of Segregating Sites Using Environmental DNA (eDNA)
Authors: Ai Qiaoyun , Yuan Hao , Wang Ying , Li Chenhong 
Published: February 2025

ABSTRACTThe advance of environmental DNA (eDNA) has enabled rapid and non‐invasive species detection in aquatic environments. While most studies focus on species detection, recent works explored using eDNA concentration to quantify species abundance. However, the differential individual DNA contribution to eDNA samples could easily obscure the eDNA concentration‐species abundance relationship. We propose using the number of segregating sites as a proxy for estimating species abundance. Segregating sites reflect the genetic diversity of the population, which is less sensitive to differential individual DNA contribution than eDNA concentration. We examined the relationship between the number of segregating sites and species abundance in silico, in vitro, and in situ experiments, using two brackish goby species, Acanthogobius hasta and Tridentiger bifasciatus. Analyses of the simulated and in vitro data with DNA mixed from a known number of individuals showed a strong correlation between the number of segregating sites and species abundance (R2 > 0.9; p < 0.01). In the in situ experiments, we analysed eDNA samples collected from mesocosm. The results further validated that the correlation (R2 = 0.70, p < 0.01) was not affected by biotic factors, including body size and feeding behaviour (p > 0.05). The cross‐validation test results also showed that the number of segregating sites predicted species abundance with less bias and variability than the eDNA concentration. Overall, the number of segregating sites is less affected by differential DNA contribution among individuals compared to eDNA concentration. This advancement can significantly enhance the proficiency of estimating species abundance using eDNA.

Published: February 2025

ABSTRACTBackgroundAdolescents and young adults (AYA) with spina bifida and/or hydrocephalus (SBH) are at a higher risk for disordered eating, poor body image and body dissatisfaction. Regrettably, there is limited research on the eating patterns and behaviours of AYA with SBH, as well as their body image perceptions.ObjectivesThe purpose of this study was to explore the nature of disordered eating behaviours among AYA with SBH and their perceptions surrounding their body image. This study represents the first investigation of its kind conducted within a Canadian population. It fills a literature gap regarding the understanding of disordered eating behaviours and body image perceptions among young individuals with SBH in Canada.MethodsThe study comprised a self‐report, cross‐sectional online survey of AYA with SBH across Canada. The survey comprised validated brief measures to evaluate eating behaviours, disordered eating and body esteem. AYA aged 12–26 years with any type of SBH were eligible to participate.ResultsTwenty‐four participants were recruited. Results indicated that AYA with SBH may face an elevated risk for eating disorders/disordered eating compared to their typically developing peers, due to a myriad of reasons not typically experienced in the general population such as bowel and bladder management, mobility issues and eating aversions. Findings also indicated that some AYA with SBH may have poor body image and that it is possible that this is not discussed in SBH clinics.ConclusionOur work underscores the urgency for further research that focuses on assessing eating disorders/disordered eating behaviours in AYA with SBH.
