The purpose of this study is to investigate the effect on flexural strength of fire-damaged concrete repaired with high-strength mortar (HSM).

Reinforced concrete beams with dimension of 100 mm × 100 mm × 500 mm were used in this study. Beams were then heated to 400°C and overlaid with either HSM or high-strength fiber reinforced mortar (HSFM) to measure the effectiveness of repair material. Repaired beams of different material were then tested for flexural strength. Another group of beams was also repaired and tested by the same procedure but was heated at higher temperature of 600°C.

Repair of 400°C fire-damaged samples using HSM regained 72 per cent of its original flexural strength, 100.8 per cent of its original toughness and 56.9 per cent of its original elastic stiffness. Repair of 400°C fire-damaged samples using HSFM regained 113.5 per cent of its original flexural strength, 113 per cent of its original toughness and 85.1 per cent of its original elastic stiffness. Repair of 600°C fire-damaged samples using HSM regained 18.7 per cent of its original flexural strength, 25.9 per cent of its original peak load capacity, 26.1 per cent of its original toughness and 22 per cent of its original elastic stiffness. Repair of 600°C fire-damaged samples using HSFM regained 68.4 per cent of its original flexural strength, 96.5 per cent of its original peak load capacity, 71.2 per cent of its original toughness and 52.2 per cent of its original elastic stiffness.

This research is limited to the size of the furnace. The beam specimen is limited to 500 mm of length and overall dimensions. This dimension is not practical in actual structure, hence it may cause exaggeration of deteriorating effect of heating on reinforced concrete beam.

This study may promote more investigation of using HSM as repair material for fire-damaged concrete. This will lead to real-world application and practical solution for fire-damaged structure.

The aim of this research in using HSM mostly due to the material’s high workability which will ease its application and promote quality in repair of damaged structure.

There is a dearth of research on using HSM as repair material for fire-damaged concrete. Some research has been carried out using mortar but at lower strength compared to this research.

The notion of students as change agents have widely been used in the campus sustainability literature, but very little has been done to unpack what it really means in practice. This paper aims to critically investigate university students’ perspectives on their role as a change agent for campus sustainability in the context of Malaysian universities.

In-depth interviews were carried out with 21 students that have been categorized as change agents through selection criteria at three leading universities in the area of campus sustainability in Malaysia. The data collected from the interviews were analysed through content-based and thematic analysis.

Findings demonstrate that students are the backbone behind the implementation of campus sustainability activities. They play the multi-faceted role of leaders, supporters and ambassadors in initiating and driving campus sustainability. The results further suggest that support and freedom to act are the empowering factors that have driven these change agents in carrying out their initiatives. However, without a position, the students’ voices are not significant.

This study provides deeper evidence-based insights on the notion of students as change agents and how it can be operationalized in the context of campus sustainability.

Halal certification is predominantly linked with the product and its production process. However, certifying price, place and promotion (3Ps) has not received enough attention theoretically and empirically. Against this backdrop, this study aims to unravel the halal certification of the marketing mix in Bangladesh’s cosmetics industry.

Fourteen mid and top executives from 12 national, international and multinational cosmetic companies were interviewed from November 2023 to January 2024. The data were analyzed using ATLAS.ti 2024 to showcase content, concept, sentiment, correlation, network and thematic analysis, exploring respondents’ perceptions aligned with Islamic principles.

The respondents held highly negative perceptions about certifying halal pricing, followed by promotion and supply chain or place. The mixed perceptions illustrate that certifying the halal product is easier than certifying the halal price, promotion and place (3Ps). Conditional and positive perceptions can foster halal certification of the entire marketing mix, while negative perceptions seem to be a threat to the halal cosmetics industry.

The findings have implications for academic, managerial and policymaking issues, benefiting halal cosmetics consumers. Based on this empirical study, halal stakeholders can determine the likelihood of certifying the entire marketing mix.

This study proposes certifying the halal status of the marketing mix against the backdrop of the scarcity of theoretical and practical premises.

The purpose of this study is to develop a new whistleblowing scale considering the conventional and Islamic perspectives in combating corruption. Whistleblowing has received great attention because it helps the corruption prevention process by revealing bad practices, improving transparency and ensuring accountability. However, not many scholars have focused on the concept of whistleblowing in the Islamic context.

The study uses a theoretical inquiry design, delving into the literature to thoroughly examine whistleblowing likelihood, Kohlberg’s theory and Maqasid Shariah. Through qualitative content analysis, relevant concepts are scrutinized and synthesized. The integration of Kohlberg’s theory and Maqasid Shariah aims to offer a comprehensive framework for comprehending whistleblowing likelihood, integrating perspectives from both Western and Islamic traditions.

This study has conceptualized the integration of the six stages of Kohlberg and Maqasid Shariah to understand whistleblowing likelihood. The study offers a scale to explain whistleblowing likelihood based on the two theories.

The correlation between Kohlberg and Maqasid Shariah reveals a nuanced relationship between individual moral evolution and Islamic ethical imperatives, in the context of whistleblowing likelihood. As individuals progress through Kohlberg’s stages, aligning with Maqasid Shariah’s emphasis on societal well-being, their inclination to blow the whistle evolves from early considerations of fear and conformity to a commitment to universal ethical principles and justice.

The new scale integrating Kohlberg and Maqasid Shariah aids ethical climates in organizations by assessing employees’ moral development and promoting ethical leadership through tailored training. Aligned with Islamic values, the scale becomes a tool for fostering ethical behavior and organizational culture, emphasizing justice and commitment to higher ethical objectives. Managers must delicately balance justice and community harmony when implementing whistleblowing initiatives to ensure a positive impact on both ethical principles and organizational cohesion.

By integrating the six stages of moral development proposed by Kohlberg, the new scale plays a role in promoting transparency and accountability for sustainable development. Furthermore, its alignment with Maqasid Shariah contributes to addressing corruption and advocating for social justice, making the scale a catalyst for societal well-being that respects cultural and religious values. Ultimately, the scale supports a socially responsible approach, reinforcing ethical behavior and contributing to the broader global agenda for sustainable and just societies.

The new scale integrating Kohlberg and Maqasid Shariah offers an innovative and interdisciplinary approach to assessing whistleblowing likelihood. This fusion provides a nuanced understanding of individuals’ ethical reasoning, aligning universal moral principles with Islamic ethics. The scale not only broadens the conceptual framework for evaluating ethical decision-making but also respects cultural diversity, making it inclusive and applicable across diverse global contexts.

The objectives of this study are to determine the level of awareness of crowdfunding and green projects among Bruneians, to investigate the preference of Bruneians regarding funding through crowdfunding as well as to evaluate the willingness of Bruneians to use crowdfunding as a funding alternative for green projects in Brunei. In addition to that, this study aims to identify the effects of environmental awareness and environmental concern on the willingness to crowdfund green projects.

A total of 177 responses from an online questionnaire distributed via convenience and snowball sampling was used for data analysis. Frequency, descriptive, correlation and regression analyses are used to achieve the aims of this study.

The study finds that the awareness of the concepts of crowdfunding and green project is high among Bruneians, but the level of their familiarity of crowdfunding platforms and climate change issues is very low. Regression analysis carried out to test the effects of awareness and concern on willingness indicates that while environmental concern has a significant positive effect on the willingness to support crowdfunded green projects, environmental awareness is insignificant.

The study highlights that government policy should be aimed at not just increasing awareness but at increasing the knowledge of the impacts of climate change issue that will raise concern and improve participation of residents in green projects. The study focuses on a rarely studied population, the people of Brunei.

The purpose of this study is to provide a comprehensive exploration of academic research on halal purchasing decisions and consumer behavior by integrating bibliometric and systematic review methodologies.

This study uses a multi-method approach, combining bibliometric and systematic review methodologies, to comprehensively analyze the domain of halal purchasing decisions and consumer behavior. A data set of 184 articles published between 2007 and 2024 was sourced from the Scopus database. The bibliometric analysis was conducted using Bibliometrix in R, facilitating performance analysis, science mapping and network analysis to explore key authors, affiliations, collaborations and thematic trends. Additionally, the systematic review examined the limitations and future research areas discussed in prior studies, providing the basis for formulating potential research questions to address identified gaps.

The study identifies significant contributions within the domain of halal purchasing decisions and consumer behavior, emphasizing the critical roles of religiosity, trust and halal certification as dominant themes. Bibliometric analysis reveals key authors, influential publications and collaborative networks, highlighting Malaysia as a central hub for research in this field. Additionally, the analysis underscores the intellectual structure and thematic evolution, identifying underexplored areas such as non-Muslim perspectives, emerging halal industries and geographic diversity. The systematic review complements these insights by addressing recurring methodological and theoretical limitations, offering targeted recommendations for future research.

This research uniquely combines bibliometric and systematic review methodologies to provide a comprehensive review of the halal consumer behavior literature, identifying limitations and gaps in prior studies and proposing actionable areas for future research.

This study aims to improve the theory of planned behavior (TPB) model by incorporating electronic word of mouth (E-WOM) as a factor influencing attitude (ATT), subjective norms (SN) and perceived behavioral control (PBC). The main goal is to study Generation Z’s intention to purchase halal cosmetics. In addition, the research examines how halal product knowledge (HPK) influences the relationships between ATT, SN, PBC and the purchase intention of halal cosmetics.

Data were collected using self-administered questionnaires from two superstores in Karachi, Pakistan, with 265 valid responses. Convergent and discriminant validity analyses were performed to ensure validity and reliability, and variable relationships were assessed using structural equation modeling.

The results revealed that EWOM significantly influences ATT, SN and PBC. ATT and PBC both significantly affect purchase intention (PI), while SN has a nonsignificant influence on PI. In addition, the study found HPK only moderates the association between ATT and PI, while moderating influence HPK does not exist in the relationship between (SN and PI) and (PBC and PI).

This study focuses on the Halal cosmetics industry in Pakistan and explicitly targets Generation Z individuals in a particular cultural environment. The aim is to examine how applying the same research design in different sectors and countries can lead to different results. In addition, the study primarily includes Gen Z consumers of halal cosmetics. Collecting data from other generational groups for future studies, such as generations X and Y, would be interesting.

This research contributes to the existing literature on halal consumption by introducing the concept of E-WOM as a factor within the TPB model. This study is particularly groundbreaking as it examines how Gen Z Pakistani Muslim consumers’ behavioral intentions toward halal cosmetic products are influenced by their HPK using the TPB model. Additionally, the paper presents an extended TPB modeling framework that could be valuable to researchers, marketers and halal experts.

This review paper aims to provide a comprehensive retrospective analysis of the research landscape in the Halal industry through a threefold approach, including bibliometric analysis, latent theme identification and examination of driving factors of research citations.

A total of 2,510 research documents, identified from the Scopus through a systematic search, were considered for review. The review methods included bibliometric analysis of the domain, application of the machine learning structural topic modeling (STM) to identify latent themes and negative binomial regression to estimate the impact of paper, author and geographical characteristics on citation rates.

In addition to bibliometric insights, the STM uncovered 10 key topics within the Halal industry literature, including certification processes, dietary practices, consumer behavior, ethical considerations, supply chain management, market dynamics, Halal tourism, verification methods, regulatory frameworks and Halal food production and marketing. Positive associations with citation rates were found for abstract length, number of keywords, paper age, number of references, funding, number of authors and international collaboration, while a negative association was observed for authorship from Malaysia.

This paper, besides providing insights into research dynamics and citation patterns, also guides future research avenues in the Halal industry.

This paper aims to provide a comprehensive and systematic overview of relevant factors that affect green purchase behavior of Muslims.

A systematic literature review was conducted to fill in the lack of conceptual clarity on the relationship between green product purchasing and Muslim consumers.

The review revealed that studies on Muslim green purchase behavior were mostly carried out in Asian countries, with the theory of planned behavior as a highly featured approach. The in-depth analysis captured more than 50 factors of green purchasing behavior of Muslims with religiosity, which was found to be the most mentioned determinant in the literature.

The finding provides three insights for future research and marketing practices: Muslim consumer behavior model development, green-halal product innovation and green Islamic marketing strategy formulation.

To the best of the authors’ knowledge, no literature review has comprehensively identified the determinants of Muslim green purchasing behavior. Therefore, enriched with bibliographical mapping, this study will systematically conduct a literature review to explain the driving factors of Muslims in purchasing green products and outline potential directions for marketers and researchers to enhance green ecosystems.
