This paper aims to examine the relation between resonant leadership (RL) and organizational citizenship behaviors while testing for the mediation effects of followers’ resilience (FR) and gender as a moderating effect, all within the United Arab Emirates (UAE) business environment.

The paper uses cross-sectional data collected through a questionnaire from 467 employees working at various organizations in the UAE. The data were analyzed using the Statistical Package for the Social Sciences (SPSS) software. The mediating and moderating effects were tested using Preacher and Hayes’s (2008) macro models.

Results confirmed that RL positively affected employees’ organizational citizenship behaviors (OCBs). It also confirmed the mediating role of FR between RL and organizational citizenship behavior. Gender moderated the relation between RL and OCB but not between RL and FR.

Managers can use RL styles to improve workers’ resilience and OCB of employees, especially females.

It is important to understand the relation between such variables in times of crisis, such as the COVID-19 pandemic, where the relationship between the leadership style of the organizational managers and employees can greatly impact employees’ behaviors and organizational performance.

Surface acoustic wave (SAW) sensors have attracted great attention worldwide for a variety of applications in measuring physical, chemical and biological parameters. However, stability has been one of the key issues which have limited their effective commercial applications. To fully understand this challenge of operation stability, this paper aims to systematically review mechanisms, stability issues and future challenges of SAW sensors for various applications.

This review paper starts with different types of SAWs, advantages and disadvantages of different types of SAW sensors and then the stability issues of SAW sensors. Subsequently, recent efforts made by researchers for improving working stability of SAW sensors are reviewed. Finally, it discusses the existing challenges and future prospects of SAW sensors in the rapidly growing Internet of Things-enabled application market.

A large number of scientific articles related to SAW technologies were found, and a number of opportunities for future researchers were identified. Over the past 20 years, SAW-related research has gained a growing interest of researchers. SAW sensors have attracted more and more researchers worldwide over the years, but the research topics of SAW sensor stability only own an extremely poor percentage in the total researc topics of SAWs or SAW sensors.

Although SAW sensors have been attracting researchers worldwide for decades, researchers mainly focused on the new materials and design strategies for SAW sensors to achieve good sensitivity and selectivity, and little work can be found on the stability issues of SAW sensors, which are so important for SAW sensor industries and one of the key factors to be mature products. Therefore, this paper systematically reviewed the SAW sensors from their fundamental mechanisms to stability issues and indicated their future challenges for various applications.

This study seeks to examine motivations, challenges and strategies implemented to sustain environmentally friendly practices in Macau hotels and the effects of the COVID-19 pandemic on such practices.

Executives in sustainability departments of hotels in Macau were purposefully targeted for the in-depth interviews. Ten executives were interviewed either face-to-face or via video call.

The findings revealed that hotels in Macau implement sustainable practices. The main motivation for their implementation was the need to protect the environment, compliance and business-driven reasons. The major challenge involved the implementation costs. The pandemic had a limited impact on the implementation of these practices.

The study recommends that the Macau government should establish clear environmental policies and regulations for hotels with guidelines and support systems. Hotels can also benchmark their performance and collaborate on sustainable practices, develop innovative financing mechanisms and cost-efficient waste recycling practices, organize customer education and engagement programs to promote environmentally friendly practices and incorporate crisis management and resilience strategies into environmental strategies.

The current study denotes that the “sustainable development” concept is crucial in Macau because the largely gaming-driven hospitality industry has been developed over the last decade, significantly impacting environmental degradation. This study examined how hotels respond to these environmental challenges and how their responses can be sustained in the long term. The authors suggest the environmental practice indicators that can be helpful for the hospitality industries in Macau. Social and economic implications are discussed based on the findings.

Although past studies have suggested that business-to-business (B2B) interfirm relationship management contributes to a firm’s omnichannel integration, little research has been undertaken to reveal how that happens. This study aims to draw upon the relational view to propose a research model that associates interfirm information technology (IT) capability and interfirm trust with omnichannel integration through interfirm integration (i.e. authority integration and cooperative integration). Furthermore, this work considers a firm’s channel usage variety as the boundary condition of the interfirm integration’s influence.

The research model was examined using a seemingly unrelated regression of archival data and matched a survey of 324 Chinese omnichannel firms.

Interfirm IT capability positively relates to authority integration, and interfirm trust positively relates to cooperative integration. Authority integration and cooperative integration are both positively associated with omnichannel integration. A high level of channel usage variety strengthens the relationship between cooperative integration and omnichannel integration.

Prior literature has called for research on the factors influencing omnichannel integration within a B2B setting. This study answers this research call by examining interfirm IT capability, interfirm trust and interfirm integration as factors associated with omnichannel integration. This work also examines how channel usage variety regulates the relationship between interfirm integration and omnichannel integration.

This paper aims to present a novel approach for computing particle temperatures in simulations coupling computational fluid dynamics (CFD) and discrete element method (DEM) to predict flow and heat transfer in fluidized beds of thermally thick spherical particles.

An improved lumped formulation based on Hermite-type approximations for integrals to relate surface temperature to average temperature and surface heat flux is used to overcome the limitations of classical lumped models. The model is validated through comparisons with analytical solutions for a convectively cooled sphere and experimental data for a fixed particle bed. The coupled CFD-DEM model is then applied to simulate a Geldart D bubbling fluidized bed, comparing the results to those obtained using the classical lumped model.

The validation cases demonstrate that ignoring internal thermal resistance can significantly impact the temperature in cases where the Biot number is greater than 0.1. The results for the fixed bed case clearly demonstrate that the proposed method yields significantly improved outcomes compared to the classical model. The fluidized bed results show that surface temperature can deviate considerably from the average temperature, underscoring the importance of accurately accounting for surface temperature in convective heat transfer predictions and surface processes.

The proposed approach offers a physically more consistent simulation without imposing a significant increase in computational cost. The improved lumped formulation can be easily and inexpensively integrated into a typical DEM solver workflow to predict heat transfer for spherical particles, with important implications for various industrial applications.

This paper aims to explore the efficiency of natural ventilation in the bedrooms of typical two-storeyed row houses with newly reconfigured design that incorporate rooftop wind catchers and side windows to create cross ventilation.

A CFD program was used to assess average air velocity coefficient (Cv) in 32 airflow cases. Parameters include location of openings with respect to wind direction, inlet-to-outlet area ratio (IOR) and opening-to-floor area ratio (OFR).

The results reveal that indoor air velocities in the cases of air entering wind catchers are generally higher than those in the cases of air entering side windows while air velocities at the openings are the opposite. The IOR of 1:2 provides best results in terms of both velocities of the indoor air and velocities at the openings. Increasing the OFR from 20% to 50% generally improves indoor air velocities and airflow rates.

This study proved that the new solution of combining one-sided wind catchers and side windows can effectively solve the problem of ventilation uniquely existing in the conditions of typical row houses by catching prevailing wind from two opposite directions into multiple rooms. The results are given as non-dimensional air velocities, which can be interpreted with any climatic data, and therefore can be applied to row houses in any locations and climatic conditions. The findings can create a new and efficient design of row houses that benefits building industry.

The aim of this paper is to research the acceptance mechanism of building information modeling (BIM) technology and to explore the differences among Architecture/Engineering/Construction (A/E/C) professionals with different individual characteristics. The proposed acceptance mechanism of BIM technology is intended to be used by industry stakeholders to propose decisions and measures, and improve the degree of BIM adoption.

Traditional hypothesis testing is adopted by the current study to empirically research the specific mechanism of A/E/C professionals accepting BIM technologies. In the one phase, a conceptual model based on technology acceptance model (TAM) and technology organization environment (TOE) theory was established and a large-scale questionnaire survey was conducted. In the other phase, structural equation modeling (SEM) was used to analyze acquired sample data, so as to empirically test the validity of the proposed linkage.

The results show first that perceived ease of use has no significant influence on perceived usefulness, and perceived usefulness has no significant effect on behavior intention as well. Second, BIM technical features and government BIM policies have positive effects on perceived usefulness, BIM technical features and organization supports have positive effects on perceived ease of use. Third, the BIM acceptance mechanism of A/E/C professionals is diverse from respondents with different characteristics, e.g. regions and working time.

The authors highlight the large sample size, as well as the nationwide context, of the questionnaire survey. Meanwhile, acceptance differences among A/E/C professionals with different demographic characteristics have been clarified using profound data and t-test. The findings of this study enrich the research on the acceptance mechanism of BIM technology, and contribute to relevant stakeholders taking targeted measures to promote the effective application of BIM technology nationwide.

Industries worldwide have been striving to serve the increasing demand of consumers alongside providing importance to environmental issues. Yet, there are concern-raising changes on the planet, such as greenhouse gas (GHG) emissions resulting in a temperature rise. India remains a vital party of the United Nations Convention on Climate Change. Henceforth, the paper aims to study the increased emissions of GHG in Puducherry, an Indian Union Territory that faces tremendous pressure owing to its denser population.

The research is designed as a case study conducted in a tyre manufacturing unit in Puducherry. The industrial sector was chosen, as it is the largest contributor (78%) of the total GHG emissions. Case studies were chosen to analyse the GHG emissions and the effects of implementing the policies and imposing interventions over time. The identified areas of improvement, proposed changes and the implemented ones with the results over a three-year period have been discussed.

The present study’s GHG inventorisation for Puducherry paved the way for preparing mitigation and adaptation plans. A total of 21 and 48 changes were incorporated to conserve fuel and power, respectively. A significant 11% reduction in power consumption and 1,113,008/litres of furnace oil was achieved. This translates to 5,115 tCO₂ and 3,306 tCO₂, respectively.

This research will help to improve the importance of climate change management in the manufacturing sector, and it will pave the way for achieving effective sustainable practices.

Such case studies could cumulatively impact the policy directives/ interventions on GHG emissions. Though this seems a small leap, putting them into practice at firm levels would contribute significantly towards achieving Sustainable Development Goals.
