A DCV performance in IAQ services during COVID-19: a study of the contractor in Malaysia
Authors: Ismail Zul-Atfi 
Published: February 2025

PurposeDemand-controlled ventilation (DCV) plays a significant role in human life by providing safe, reliable and cost-effective services that are environmentally friendly and enhance occupant satisfaction and building energy efficiency. Significant decisions are made at the early stages of building sector DCV systems, requiring effective tools to avoid measurement errors and failures in Volatile Organic Compound (VOC) generation. The continuous upgrading of this sector is necessary to respond to technological advances, environmental changes and increased ventilation demands. Integrating indoor air quality (IAQ) and machine learning algorithms (MLA) proves promising, as the scope of DCV typically does not extend beyond the footprint of the building; it does not encompass IAQ within a Corona Virus Disease 2019 (COVID-19) infection risk information. Therefore, integrating IAQ with MLA provides a comprehensive overview of the building sector’s DCV systems. However, this integration poses challenges, particularly in DCV activities, as they are among the most complex systems involving numerous processes critical for making important decisions. This study aims to identify how digitalized construction environments can integrate DCV into their processes.Design/methodology/approachThis study reviews the literature on integrating IAQ with MLA systematically, aiming to analyze the DCV need for this integration and its benefits. It proposes a direction for a conceptual framework, simulation and causal explanation of the problems using the bootstrapping technique and Cronbach’s alpha factor analysis to establish the requirement for facilitating specific ventilation control processes to be incorporated into the system approaches in managing infection prevention and energy efficiency in the building sector’s DCV system.FindingsThis study proposes a conceptual framework for analyzing IAQ within a COVID-19 context and MLA embedded in systems that may impact DCV practices. The conceptual framework comprises six key constructs: virus detection, occupant ventilation behavior, DCV energy consumption, diagnostic evaluation, temperature perception cluster and indoor environmental quality. The conceptual framework underscores the importance of early integration of DCV in the design phase to identify alternative methods to cogenerate, monitor and optimize DCV.Originality/valueSo far, this study advances the knowledge of how digitalized construction environments can ensure DCV delivery. The testing results highlight four significant relationships between the constructs of strategies and the constructs of occupant-density factors in the Malaysian dataset within the existing conceptual framework. Hence, the framework designed for developed countries or US companies can enhance IAQ ventilation strategy options in Malaysia’s G7 contractor companies. A future study can validate the framework across the design phase with different construction stakeholders.

Published: February 2025

PurposeThis study investigates the effects of diversity and specialty on the performance of public research and development (R&D) teams and addresses a gap in research that has largely focused on diversity without adequately considering specialty. It explores the influence of educational background and level, as aspects of diversity, and specialty on team performance and innovation, particularly among leaders and members.Design/methodology/approachEmploying panel data from the National Science and Technology Information Service and a modified rank-normalized impact factor index for innovation performance, this study differentiates between educational background and level. It examines their influence on the performance of public R&D teams by focusing on the dynamics between diversity and specialty in leader and member groups.FindingsThe study finds that diversity in educational level boosts performance in member groups, whereas “leaders” performance is more closely linked to their educational background and specialty. The results underscore the importance of managing educational diversity and specialty within leader and member groups and highlight the need to avoid a unilateral emphasis on singular necessity.Originality/valueThis study’s novelty lies in its examination of the influence of educational diversity and specialty on innovation performance within the framework of inter-organizational public R&D teams, considering the interaction between these factors among leaders and members. It offers new insights for establishing inter-organizational teams and contributes a unique perspective to the literature on innovation management.
More sustainable denim fading process of two different indigo dyed denim fabrics with laser treatment
Authors: Uysaler Tuna , Altay Pelin , Özcan Gülay 
Published: February 2025

PurposeLaser fading, commonly used in the denim industry, is a computer-controlled, dry, ecological finishing method whereas conventional methods include high water, energy and time consumption. Resolution and pixel time are crucial parameters of laser source influencing the effect of laser treatment. The purpose of this study is to determine the optimum laser parameters of CO2 laser followed by enzyme washing and to compare the tensile strength and color values of laser-treated denim fabric with that of conventional enzyme-faded.Design/methodology/approachTwo different indigo-dyed, sulfur bottom-indigo-dyed and only indigo-dyed organic cotton denim fabrics with different unit weights, were lasetreated with different laser parameters and then subjected to 10 min enzyme washing. Tensile strength, abrasion resistance, and change in fabric unit weight were tested. CIE (L*a*b*, ΔE*, h°, C*) color values, color strength (K/S), yellowness and whiteness indexes were measured to identify the color differences. Color fastness tests including washing, rubbing, light, water and perspiration fastness were investigated.FindingsMost effective laser fading in terms of good mechanical properties and color values was obtained at 40 dpi resolution and 300 µs pixel time.Originality/valueConventional enzyme fading of denim fabrics is a wet process and requires a long process time of 40–45 min and high temperatures, leading to high energy and water consumption. Laser fading, on the other hand, is a dry and ecological method, but causes a decrease in mechanical properties of the fabric, and an increase in yellowness. In this study, unlike the similar studies in the literature, denim fading was carried out by a combination of laser treatment followed by only 10 min enzyme washing in order to eliminate or minimize the drawbacks of the denim fading, such as high energy and water consumption for enzyme fading and decrease in mechanical properties of the fabric and increase in yellowness for laser fading. This method was applied to two different dyed denim fabrics, sulfur (bottom) and indigo (top) and laser process conditions were optimized to achieve the desired fading effects compared to conventional enzyme fading.

Published: February 2025

PurposeThis research explores the impact of trust in online information, parasocial interaction, online flow experience, sharing fake news and corporate credibility on companies’ resilience to negative information.Design/methodology/approachA conceptual research model was developed, employing the flow theory to fill gaps in the literature. A cross-sectional national online survey was conducted among 1,550 respondents aged 16–74 in an emerging market, utilizing a quantitative-based approach; the data were then analyzed using structural equation modeling.FindingsTrust in online information and parasocial interactions was found to impact the online flow experience, with parasocial interaction positively affecting it optimally. The sharing of fake news is affected by parasocial interaction and the online flow experience, which in turn affects corporate credibility.Originality/valueCorporate credibility is shown to be an antecedent of resilience to negative information and word-of-mouth communication in companies, the former having a direct influence on the latter. The study hence has significant theoretical and managerial implications for communication and marketing.

Authors: Zhu Chunchu , Chen Xunjie , Yi Jingang 
Published: February 2025

Abstract
Current studies on human locomotion focus mainly on solid ground walking conditions. In this paper, we present a biomechanic comparison of human walking locomotion on solid ground and sand. A novel dataset containing 3-dimensional motion and biomechanical data from 20 able-bodied adults for locomotion on solid ground and sand is collected. We present the data collection methods and report the sensor data along with the kinematic and kinetic profiles of joint biomechanics. The results reveal significant gait adaptations to the yielding terrain (i.e., sand), such as increased stance duration, reduced push-off force, and altered joint angles and moments. Specifically, the knee angle during the gait cycle on sand shows a delayed peak flexion and an increased overall magnitude, highlighting an adaptation to maintain stability on yielding terrain. These adjustments, including changes in joint timing and energy conservation mechanisms, provide insights into the motion control strategies humans adopt to navigate on yielding terrains. The dataset, containing synchronized ground reaction forces (GRFs) and kinematic data, offers a valuable resource for further exploration in foot-terrain interactions and human walking assistive devices development on yielding terrains.
On Order Elevation for Unstructured Finite Volume Solvers Using Defect Correction
Authors: Jayasankar Akhil , Ollivier-Gooch Carl 
Published: February 2025

Abstract
Much of the effort in improving the accuracy of computational fluid dynamics (CFD) simulations is focused on mesh refinement and adaptation although studies have shown that the use of high-order methods are more efficient in improving accuracy. Stability issues, complexity of implementation, and demand of computational resources are some of the key factors hindering the use of high-order methods in commercial CFD solvers. This paper demonstrates an improvement in the order of accuracy of finite volume solutions on unstructured meshes without using a high-order solver. Defect correction and the error transport equation method are the techniques discussed, along with the method for obtaining an appropriate estimate of the truncation error, which is crucial in both these techniques. Methods to obtain high-order interpolation of the control volume averages and high-order integral functionals along curved boundaries are also discussed. Third-order accurate results are obtained for a variety of problems, including the 2D Euler equations, without using a third-order discretization scheme.
Investigation of Grooved Front Plate for Inlet Swirl Reduction in Brush Seals
Authors: Aboseada Abdullah , Pekris Michael J , Chew John W. 
Published: February 2025

Abstract
Brush seals are plausible replacements for conventional labyrinth seals in gas turbine internal air systems. They can offer superior leakage performance due to their compliant nature and reduced effective clearance during operation. However, highly swirling flow and aerodynamic forces on the upstream bristles could lead to bristle back aero-elastic instability at high-shaft speed locations. Previous research has shown that the bristles in an idealized pack are displaced from their equilibrium position at swirl velocities of 150m.s-1 and above for a bristle diameter of 0.1mm. This study investigates grooves as a means of improving brush seal robustness in these locations by reducing inlet swirl incident on the bristle pack. A parametric study of a simple groove geometry was conducted using CFD and a porous medium representation of the bristle pack to achieve representative seal leakages. Groove length, width, angle and pitch were identified as important parameters for swirl reduction. The performance of ribs from previous research can be replicated and improved upon. A Design of Experiments (DOE) approach was implemented to investigate a novel groove design geometry. Combining a horizontal channel with an inclined groove enables a higher spacing to achieve the same swirl reduction due to drag and flow channeling/mixing effects at the inner radius. The resulting trends indicate that the novel design performs as intended, for the selected boundary conditions, in substantially reducing the swirl and bristle aerodynamic loading, thus helping to mitigate the above risk of premature seal deterioration and failure.

Published: February 2025

This systematic review aimed to analyze the methodologies used to teach swimming skills to individuals with disabilities and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. 13 studies were reviewed to identify the most effective approaches in aquatic education. The studies analyzed included participants with a range of disabilities, such as autism spectrum disorder, cerebral palsy, and visual impairments. Key findings suggest that tailored methodologies like the Halliwick Method and Water Exercise Swimming Program improve motor and social skills significantly, while inclusive frameworks such as the Sherrill Swimming Model promote participation across diverse groups. In addition, the Comprehensive Aquatic Method offers an innovative framework, which includes cognitive challenges and creative activities promoting social and emotional development. However, gaps remain in addressing sensory disabilities, particularly hearing impairments. This review provides insights for educators and practitioners to develop inclusive aquatic programs while highlighting the need for further research into underexplored populations and socioaffective outcomes.

Published: February 2025

ObjectiveTo investigate the antecedents to episodes of aggression and the use of coercive measures in inpatient mental health settings, organize and explore their relationships and patterns through thematic analysis, identify gaps in the literature and provide insights for future research.IntroductionThe use of coercive measures in inpatient mental health settings remains controversial and ethically challenging. Despite an international consensus on the need to reduce their use, the antecedents to aggression and episodes involving coercive measures remain insufficiently explored. This review seeks to address this gap by systematically mapping the evidence of these antecedents and exploring their relationship, providing a foundation for future research.Inclusion criteriaStudies included were those published from 2014 to the present in the English language, focusing on either adult mental health inpatients or mental healthcare professionals aged 18 years or older involved in episodes of aggression or exposure to coercive measures in both acute and long-term inpatient mental health settings. Included studies must address antecedents to aggression or the use of coercive measures. Exclusions apply to studies focusing exclusively on behaviours unrelated to aggression or coercive measures, studies conducted in non-inpatient settings and those involving child, adolescent, geriatric or forensic populations.MethodsThe review will follow the Joanna Briggs Institute methodology for scoping reviews. The search strategy will cover key databases, including Ovid Medline, APA PsycINFO and Scopus, with reference list screening to ensure comprehensive coverage. Initial exploratory searches were conducted in June 2024, with the formal searches updated in January 2025. Studies will be screened against the inclusion criteria, and data will be extracted using a standardised form adapted to the review objectives. Grey literature will be excluded, focusing on peer-reviewed evidence. The analysis will include descriptive mapping of the antecedents to aggression and the use of coercive measures, supplemented by thematic analysis to organize and explore patterns and relationships between them. Results will be presented in a descriptive summary, supported by thematic analysis and descriptive statistics.Ethics and disseminationEthical approval is not required since this study uses existing published literature. The results will be disseminated through a peer-reviewed journal and presented at relevant international conferences.
