Large volumes of complex and diverse data sources present a tremendous barrier for big data applications (BDAs) in digital library in terms of processing and extracting relevant insights. The purpose of this study is to examine librarians’ perceptions of BDAs and management for digital library services in selected academic libraries in Kwara State.

The research design that was adopted in this study is the cross-sectional research design. The total population for this study is 58 (58) library professionals. Owing to the small population of this study, total enumeration sampling technique was adopted for this study. Hence, the sample size for this study is 58 (58). Questionnaire was used for data collection. Collected data were analyzed using descriptive statistics.

The study demonstrated that digital library services provided include virtual reference services, institutional repositories and personalized content recommendation. Also, the librarians were aware of BDAs like Apache Hadoop and Python. It was showed that BDAs are used for resource transfer, borrowing management, user needs, usage tracking and personalizing content recommendations. Results showed that open-source software and hardware, and training on handling diverse data sets are essential for the management of big data. Challenges associated with the use of BDAs include scalability limitations, complex data structures, lack of big data processing, power supply issues and data privacy.

This study provides unaddressed questions and gaps in the area of using BDAs for the provision of digital library services, especially in developing countries like Nigeria.

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 paper aims to investigate the principles guiding sustainable waste management practices within the framework of Maqasid al-Shari’ah. The purpose is to address the environmental challenges arising from economic expansion, population growth and resource consumption, which often lead to unsustainable waste management practices and hinder economic growth. The focus is on aligning waste management principles with the ethical objectives outlined in Shari’ah.

Adopting a qualitative content analysis method and an inductive approach to outline the constituent elements that formulate the framework, this study investigates the objectives of Maqasid al-Shari’ah to identify underlying elements crucial for sustainable waste management.

The study reveals how the principles embedded in Maqasid al-Shari’ah provide a foundation for effective waste management practices. The findings emphasize the importance of integrating these principles into human behavior to ensure that waste management aligns with the Shari’ah viewpoint. The insights shed light on the role of Maqasid al-Shari’ah in managing waste sustainably and contributing to environmental conservation efforts.

This research contributes to the field by offering a unique perspective on waste management practices through the lens of Maqasid al-Shari’ah. The study’s originality lies in its exploration of how Islamic ethical objectives can guide sustainable waste management, providing a framework that goes beyond conventional approaches. The incorporation of a comprehensive literature review enhances the authenticity and novelty of the proposed waste management framework.

This study aimed to analyse user experiences and perceptions of eRupee banking applications in India, focussing on understanding the key factors driving user satisfaction and dissatisfaction.

A comprehensive text-mining approach was employed to analyse 5,176 user reviews collected from the Google Play Store. Sentiment analysis and latent Dirichlet allocation (LDA) were used to classify reviews and uncover prevailing themes.

The analysis revealed that positive reviews highlighted the themes of usefulness, convenience, satisfaction, app attributes, and ease of use. Negative reviews emphasise issues related to lack of trust, faulty updates, unreliability, security concerns, and inadequate customer support. The Logistic Regression model demonstrated superior performance in predicting user sentiments, achieving an AUC of 0.7926 and an accuracy rate of 77.90%.

This study was limited to reviews from a single-platform source. Future research could incorporate data from multiple online sources and employ qualitative methods to gain deeper insight. Additionally, longitudinal studies and cross-cultural analyses are recommended to capture evolving user sentiments and global perspectives.

The findings provide actionable insights for bank managers, app developers and policymakers to enhance eRupee applications by addressing identified issues and leveraging positive aspects to improve overall user experience and satisfaction.

This study makes a novel contribution to the literature on digital currency and advanced text-mining techniques using machine-learning models to analyse user feedback in the context of an emerging economy. The proposed conceptual model and practical recommendations serve as the foundation for future research and practical development in digital financial services.

This paper aims to explore the role and relationship of ethics and morals in technology, specifically examining how Islam, as a religion that emphasizes spirituality and sacredness, can uniquely influence the concept of robot rights.

The existing literature on robot rights and Islamic perspectives has been critically reviewed to address the study’s objectives.

In Islam, robots are viewed similarly to property ownership, where the owner holds responsibilities rather than absolute control. Islamic ownership rights are distinct compared to conventional ownership models. In Islam, private ownership is limited, as God is considered the ultimate owner of all assets. Assets, including robots, must be managed according to Islamic values and ethics. Unlike conventional ownership, where the owner can dispose of their property without justification, Islamic principles grant more rights to assets (including robots). This difference arises from the sacred origins of economic resources in Islam, which extends to the treatment of assets as inputs in an economy. Therefore, spirituality, as defined in Islam, uniquely influences the rights of robots.

As robotics becomes an increasingly significant part of our lives, religion plays a growing role in shaping the ethical and moral framework within which robots operate. This study is among the first to present an integrative framework and evaluate robot rights from an Islamic economics perspective.
