This paper aims to fabricate a polymer-based polyethylene glycol (PEG) coating with acrylic resin as a binder that can show antiviral activity against the feline coronavirus (FCov) on the glass substrate.

The PEG/acrylic coating systems of different weight percentages were coated on the glass substrates using the spray-coating method and cured at room temperature for 24 h.

The coating system containing 20 Wt.% of PEG exhibits the highest antiviral activities as high as 99.9% against FCov compared with other samples.

Findings will be useful in the development of antiviral coating for PPE fabrics by using the simple synthesis method.

Application of PEG as an antiviral agent in the antiviral coating system with high antiviral activities about 99.9%.

This paper aims to explore dual solutions for the flow of a hybrid nanofluid over a permeable melting stretching/shrinking sheet with nanoparticle shape factor, second-order velocity slip conditions and viscous dissipation. The hybrid nanofluid is formulated by dispersing alumina (Al₂O₃) and copper (Cu) nanoparticles into water (H₂O).

The governing partial differential equations (PDEs) are first reduced to a system of ordinary differential equations (ODEs) using a mathematical method of similarity transformation technique. These ODEs are then numerically solved through MATLAB’s bvp4c solver.

Key parameters such as slip parameter, melting parameter, suction parameter, shrinking parameter and Eckert number are examined. The results reveal the existence of two distinct solutions (upper and lower branches) for the transformed ODEs when considering the shrinking parameter. Increasing value of Cu-volume fraction and the second-order velocity slip enhances boundary layer thicknesses, whereas the heat transfer rate diminishes with rising melting and suction parameters. These numerical results are illustrated through various figures and tables. Additionally, a stability analysis is performed and confirms the upper branch is stable and practical, while the lower branch is unstable.

The analysis of hybrid nanofluid flow over a shrinking surface has practical significance with applications in processes such as solar thermal management systems, automotive cooling systems, sedimentation, microelectronic cooling or centrifugal separation of particles. Both steady and unsteady hybrid nanofluid flows are relevant in these contexts.

While the study of hybrid nanofluid flow is well-documented, research focusing on the shrinking flow case with specific parameters in our study is still relatively scarce. This paper contributes to obtaining dual solutions specifically for the shrinking case, which has been less frequently addressed.

This study aims to examine the association between board characteristics (namely, diligence, independence, gender diversity, size and expertise) and sustainability-related disclosures (SRD) in Malaysia.

A robust SRD index of 409 items is used to derive SRD scores for 56 Malaysian listed companies from 2018 to 2020, yielding 168 observations. Pooled ordinary least squares is applied to test the research hypotheses and model.

The authors find that board members in audit committees and female board members show a significant relationship with SRD, casting doubt on the widely held belief that other board characteristics (such as size, diligence, independence and expertise) independently impact SRD. However, the authors find that market influence (firm value) and firm size are associated with SRD.

SRD is at its nascent stage, and companies are cherry-picking on what to report, as evidenced in the SRD scores. Regulators and policymakers must recognize the complex interplay between various factors impacting SRD for the timely issuance of comprehensive rules for firms to comply. The regulators’ drive for more female board representation can be a boost to enhance the sustainability agenda for Malaysian listed companies. The SRD scoring template can be used on post-2020 data to investigate the sustainability maturity of Malaysian listed companies.

The authors evidence that SRD practice is in the early stages of maturity using the comprehensive SRD scoring template. Although the findings contradict prior studies, the authors believe this is driven by the robust SRD measure based on the latest Global Reporting Initiative and Bursa rules.

This study aims to explore the factors influencing Muslim behavior toward halal nutraceutical products in Malaysia.

This study used a quantitative survey approach to 400 Muslim respondents in Malaysia who have experience in consuming or purchasing nutraceutical products. The sampling technique used was multistage stratified sampling, and the data was analyzed using structural equation modeling.

This study revealed that perceived safety is the most influential factor contributing to Muslims’ behavior toward halal nutraceutical products in Malaysia, followed by Islamic values, trust, religiosity, maqasid al-Shariah and halal literacy.

This study has only focused on halal nutraceutical products from the perspective of Muslim consumers in Malaysia.

This study contributes to understanding the factors that influence Muslim consumers’ behavior toward halal nutraceutical products by adopting the Social Cognitive Theory and Islamic Theory of Consumer Behavior.

New generations actively seek employment in organizations that resonate with their values, mission and sense of purpose. However, perceptions of organizational politics (POP) associated with unethical practices detrimentally affects meaningful work experiences and employee retention. Ethical leadership emerges as a critical factor in mitigating these negative effects. This study aims to propose a comprehensive model that examines the impact of ethical leadership on two crucial work outcomes: meaningful work and turnover intention. The mediating role of POP is explored, shedding light on the intricate dynamics within organizational contexts.

To test the model, the authors use a sample of 261 respondents who completed an online questionnaire shared on social networks. Partial least squares is used for data analysis.

Results evidence that ethical leadership reduces employees’ POP, increases meaningful work and reduces turnover intention. One dimension of POP – communication – mediates the relationship between ethical leadership and work outcomes. Furthermore, meaningful work mediates the relationship between ethical leadership and turnover intention.

The study offers practical suggestions for managers to mitigate the negative impact of POP on meaningful work and employee retention.

This study adds to previous research by analyzing the separate and combined effects of ethical leadership on five dimensions of POP – communication, resources, decisions, reputation and relationships. Furthermore, this study adds empirical evidence on how POP influence meaningful work and employee retention.

Furthermore, it emphasizes the need for further research to validate the model's effectiveness and explores its potential global policy implications.

Retrofitting and rehabilitation are part of the conservation approach in Heritage Building Conservation Guideline 2016 in Malaysia. Heritage buildings can be retrofitted to preserve their culture and history while being given a new lease. Rehabilitation is a preservation requirement that is more flexible since it assumes that the structure has already deteriorated to the point where repairs are required to prevent further deterioration. Although the strategies of these two approaches are different, their combination resulted in sustainable heritage building maintenance. This long-term maintenance strategy is necessary, especially for Malaysia's numerous heritage schools, which have serious maintenance problems as a result of infrequent maintenance, repairs, and funding shortages.

This study involved secondary data from an intensive literature review along with a comparative study from articles review and context analysis. A comparative study was conducted to determine the typical issue with heritage school buildings and the best maintenance practice for these structures. Finally, it involved a SWOT analysis study of retrofitting and rehabilitating heritage school buildings will be discussed in this study as well.

The findings of this study will focus on developing a strategic planning framework and maintenance for heritage school buildings in Malaysia to achieve sustainable maintenance. It will also highlight sustainable maintenance best practices for heritage school buildings in Malaysia. Finally, SWOT analysis will go over the pros and cons of retrofitting and rehabilitation for these buildings.

This paper put forward the requirements of strategic planning in heritage school buildings and outlines the significance of sustainable maintenance for educational buildings. It is an alternative for cost savings that has not been extensively investigated in previous studies.

This paper aims to investigate the motivating factors for Malaysian governmental agencies (MGAs) to embrace chatbot technology.

Based on the technology-organisation-environment (TOE) framework, using purposive and snowball sampling techniques, 262 online data from the MGA top management were gathered. Smart PLS4 was employed to test the hypotheses of the study.

The findings demonstrated positive relationships between technological readiness (TR), big data analytics (BDA), organisational readiness (OR), organisational learning capabilities (OLC) and governmental policies (GP) concerning chatbot adoption intention and also the relationship GP with OR. A mediating effect was also observed, which indicated the OLC role in positively mediating BDA, the OR role in positively mediating OLC and the OR role in positively mediating GP with OR and OLC as sequential mediators in the relationship between BDA and chatbot adoption intention. Furthermore, the presence of citizen demand (CD) strengthened the relationship between TR, OR and chatbot adoption intention.

This study was limited to Malaysian federal government agencies who still not adopting Chatbots.

The findings offer valuable insight into factors affect the adoption of chatbots among Malaysian government agencies. Stakeholders, including department heads, can use these findings to strategically enhance counter service by promoting chatbot adoption.

The study demonstrated that the TOE framework was effective in identifying the factors contributing to the decision-making process for adopting chatbots across MGAs. Organisational readiness and organisation learning capability was found to sequentially mediate the relationship between big data analytic and intention to adopt chatbot. Citizen demand was found to have moderation effect on the relationship between organisational readiness and technological readiness towards the intention to adopt a chatbot.

This study aims to examine the factors of implementing istibdal waqf and generating cash waqf funds through istibdal in Penang. This study was based on the previous problem statements, stating that waqf property could not be developed due to lack of cash funds. This has allowed the study to explore the factors for implementing istibdal waqf property and the extent to which the istibdal method can generate cash waqf funds in Penang.

This study adopted a qualitative method by conducting semi-structured interviews to achieve its research goals. Semi-structured interviews were conducted to comprehensively understand the current practice on istibdal cases in Penang State Islamic Religious Council (MAINPP) through official institutions concerned with waqf management practices in Penang. This research relied on purposive sampling to select the informants. It is a sampling strategy to select the informants in advance based on the research question. To achieve the purpose of this study, two officers from MAINPP were selected based on their working experience and specialisation criteria. As a result, several themes were successfully defined from the interview data before being analysed based on the content analysis method.

The results present three istibdal implementation processes outlined by MAINPP, namely, the istibdal implementation process for waqf land involved in the acquisition by state authorities (PBN), non-productive waqf land and istibdal applications from certain parties. The results also reveal two factors in implementing istibdal in Penang: the acquisition of waqf land by PBN and the application of istibdal for cemeteries by the Islamic Centre of Universiti Sains Malaysia. From the point of cash fund generation, no case of istibdal implementation records the generation of cash funds to MAINPP. Thus, this study ends with proposals for improving the process and implementing istibdal in Penang to generate cash funds to help MAINPP manage waqf properties.

The study only focused on implementing factors and generating cash waqf funds through istibdal in Penang. At the same time, it can be expanded to other states like Terengganu, Johor and Kelantan. This study only interviewed officers who manage matters related to the affairs of waqf properties. Therefore, it is believed that the study can be extended to other respondents, such as experts in cash fund generation investments and others.

This study proposed improvements to the policy and practice of istibdal waqf property to MAINPP after the shortcomings were identified throughout this study. If improved, these proposals will significantly impact the waqf properties involved in implementing istibdal, where it can generate cash and ensure the constant economic value of waqf properties.

This study has great implications for society through the development of a cash waqf fund that can provide great benefits to the needy, in addition to increasing funds for the welfare expenditure of Muslims through rental income, investment and development. Progress and significant impact on waqf property can provide a high indicator of the efficiency of an organisation in managing waqf property. This can attract the interest of the public, especially the wealthy, to always fulfil welfare through the waqf mechanism and share the wealth with the needy.

This study contributes to comprehensive field data on the implementation of istibdal in Penang. The data analysis results are significant to be used by the waqf property management.

This study aims to investigate factors that drive or deter audit firms (AFs) from disclosing audit quality (AQ) information to stakeholders in Iran. Furthermore, information items that should be contained in their disclosures are examined.

The study followed an interpretive approach. In this regard, 21 semi-structured and face-to-face interviews were conducted to explore the viewpoints of audit partners and investment managers. Interviewees were selected by snowball sampling method. The transcripts of audio records were prepared, and a thematic perspective was applied to evaluate transcriptions.

Participants’ interpretations indicate that certain factors, such as signaling to stakeholders, active audit committees and investor demand, promote transparency among Iranian AFs. Nonetheless, this inclination is deterred by some concerns, including poor AQ, lack of financial resources, lack of legal enforcement, fear of raising stakeholders’ expectations, inactive professional associations and contextual factors which should be addressed. Interviewees believe five items should be contained in AFs’ disclosures to enhance transparency.

This study contributes to recognizing factors explaining AFs’ behavior in the context of an Islamic country. Furthermore, the type of disclosure that should be contained can provide good insight for standard setters or oversight bodies.

The semi-structured interviews shed light on the contextual factors that influence transparency within the accountancy profession, either enabling or hindering it. Additionally, it is crucial to consider each country’s unique characteristics when determining the disclosure items in transparency reports.
