The purpose of this paper is to investigate the relationship between CRM dimensions (i.e. customer orientation, CRM organization, knowledge management, and technology based CRM) and various aspects of organization performance (i.e. financial, customer, internal process, and learning and growth) in Malaysian hotels.

This is a quantitative study, the response came from the managers of 152 Malaysian hotels (3 to 5 star) and data collected was subjected to correlation and regression analysis in pursuance of the study's stated objectives.

The results of this study suggest that all dimensions of CRM (i.e. customer orientation, CRM organization, knowledge management and technology based CRM) have a positive and significant impact on different perspectives of hotel performance. However, CRM technology failed to show a significant relationship with learning and growth perspective of hotel performance.

An emphasis has been placed on the direct relationship between CRM dimensions and organization performance perspectives as well as, the study concentrated only on 3 to 5 star hotels.

Meaningful implications are made that building an extensive and effective CRM dimensions in hotel firms is crucial to face a high competition and improve performance in Malaysia hotel sector.

The paper addresses CRM dimensions issues specifically for hotels in Malaysia.

This research aims to examine and compare differences in waṣiyyah wājibah (obligatory bequest) (WW) practices in Malaysia and Indonesia.

This is an exploratory qualitative research, employing a thematic analysis approach. Six Muslim Wills (State) Enactments [Enakmen Wasiat Orang Islam (Negeri)] in Malaysia, Islamic Law Compilation (Kompilasi Hukum Islam) in Indonesia, two fatwas (ruling in religious matters) and one court case from each country are analysed. Data is collected from official government websites and other reliable search engines.

First, the findings show that the WW practice in both countries is similar regarding the quantum of the beneficiaries' entitlement. However, the practice varies between both countries in terms of the types of beneficiaries and how the bequest is distributed. Second, this study shows the potential of WW as an estate planning instrument to complement the existing instruments in each country, especially when addressing family members who are not entitled to succeed by farāʾiḍ (Islamic inheritance law).

The provision of relevant laws and regulations regarding WW needs to be formulated to guarantee the well-being of dependants. The differences in practice between the two countries can be a guideline to expand the WW scope and context to other Muslim countries.

This study is the first attempt to compare WW between two Muslim-majority countries focusing on relevant laws, court cases and regulations.

Based on the extended theory of planned behavior, this study aims to examine potential intentions-related factors that affect Islamic tax compliance moderated by information and communication technology (ICT) adoption.

A quantitative cross-sectional design was used to distribute questionnaire sets to 975 working Muslim Omanis by using convenience sampling method. PLS-SEM was mainly used to examine the data.

All the factors determine behavioral intention to pay Islamic tax (BIIT), which significantly predicts Islamic tax compliance behavior (ITCB). However, perceived control behavior negatively determines intention. ICT adoption moderates the link between BIIT and ITCB.

This study offers both practical and theoretical implications that can guide efforts to promote Islamic tax compliance and advance our understanding of tax behavior within the ETPB framework.

This study accounted for crucial factors determining intention than earlier ones using the ETPB. Considering technological advancements, the study also assessed the moderating role of ICT between BIIT and ITCB.

This paper aims to explore the perception of business owners’ on zakat compliance by examining the influence of intention to pay zakat, attitude, subjective norm, perceived behavioural controls and past behaviour.

A total of 575 self-administered questionnaires were distributed to active business owners in Algeria. The data were analysed using variance-based structural modelling (PLS-SEM) to examine the hypothesised relationships.

The results revealed that the relationships between attitude, subjective norm and perceived behavioural controls were positive and significant with the intention to comply with zakat, which significantly influences the compliance behaviour of zakat.

In a country like Algeria with a high poverty rate, the current findings would benefit authorities in understanding zakat compliance and assist zakat administration in formulating and implementing strategies to promote compliance.

The present research extends the existing zakat knowledge from behavioural perspectives by using the extended theory of planned behaviour. In addition, it considers the mediating role of intention demonstrated in the zakat compliance setting.

This study aims to explore the current Green practices implemented in Malaysia higher education institutions toward sustainability attainment by developing a multi-disciplinary comprehensive policy framework to further extend the collaboration among sustainability practitioners in providing integrated data on Green indicators linked to economic, social and environmental dimensions of sustainability in higher education institutions.

Primary data which comprises of sustainability archival documents from sixteen universities in Malaysia was used to explore the extent of Green practice for sustainability. In addition, this study also used secondary data from existing literature on sustainable development in Malaysia higher education institutional context.

Findings from the examined 16 universities and prior sustainability studies in Malaysia universities suggest that higher education institutions in Malaysia are presently implementing Green practices in their university campuses toward attaining sustainability.

Qualitative data is only collected from higher education institutions in Malaysia. Hence, findings from this study cannot be generalized to universities in other countries.

This study provides insights toward infusing Green campus paradigms from a technological perspective to facilitate the exchange of information between sustainability practitioners to produce innovative solutions for addressing sustainability challenges.

This research developed a policy framework that provides trans-disciplinary approach to be adopted by higher education institutions in Malaysia and further beyond toward attaining sustainability. Socially, this study provides Green indicators that act as a reference manual and road map toward sustainable development in higher education institutions.

A novel multi-disciplinary comprehensive policy framework is developed grounded on identified Green indicators integrated to provide information on how sustainability practitioners can implement Green practices paradigms across universities. Furthermore, the Green indicators can be used as metrics to provide data for Green practice measurement and monitoring in higher education institutions.

This paper aims to analyze the role of waqf in the socio-economic development of the organization of the Islamic Cooperation (OIC) countries. Various projects currently use waqf as an instrument for socio-economic development, as reported in the scholarly literature. This study will investigate this literature to explore trends in waqf studies and the role of this Islamic form of endowment in the socio-economic development of OIC countries.

This systematic literature review focuses on peer-reviewed journals and data obtained from the Mendeley database using specific criteria to analyze the socio-economic developmental role of waqf in OIC countries from 2011‐2020.

The socio-economic developmental role of waqf in OIC countries has been widely studied. In total, 68 academic articles were found that are relevant to themes of poverty alleviation, social welfare, entrepreneurship, education, health services and religious facilities. They reveal that the role of waqf in social welfare was the most discussed topic in the research. In addition, the majority of studies used an interview method to study waqf institutions in nine OIC countries. Furthermore, the number of publications on the theme has increased significantly every year, although the largest proportion occurred in unindexed journals.

This study provides an overview of research trends in the socio-economic developmental role of waqf. Its results can provide practical input for waqf institutions as they encourage its practice in OIC countries, and for policymakers in formulating their management strategies to promote the role of waqf in the social and economic aspects of society.

This paper reviews the current development of the socio-economic role of waqf in OIC countries. It will help researchers improve their understanding of this role. It will also provide waqf managers in OIC countries with adequate information on waqf projects which they can implement to achieve socio-economic development in their countries.

Authenticating an individual through voice can prove convenient as nothing needs to be stored and cannot easily be stolen. However, if an individual is authenticating under duress, the coerced attempt must be acknowledged and appropriate warnings issued. Furthermore, as duress may entail multiple combinations of emotions, the current f-score evaluation does not accommodate that multiple selected samples possess similar levels of importance. Thus, this study aims to demonstrate an approach to identifying duress within a voice-based authentication system.

Measuring the value that a classifier presents is often done using an f-score. However, the f-score does not effectively portray the proposed value when multiple classes could be grouped as one. The f-score also does not provide any information when numerous classes are often incorrectly identified as the other. Therefore, the proposed approach uses the confusion matrix, aggregates the select classes into another matrix and calculates a more precise representation of the selected classifier’s value. The utility of the proposed approach is demonstrated through multiple tests and is conducted as follows. The initial tests’ value is presented by an f-score, which does not value the individual emotions. The lack of value is then remedied with further tests, which include a confusion matrix. Final tests are then conducted that aggregate selected emotions within the confusion matrix to present a more precise utility value.

Two tests within the set of experiments achieved an f-score difference of 1%, indicating, Mel frequency cepstral coefficient, emotion detection, confusion matrix, multi-layer perceptron, Ryerson audio-visual database of emotional speech and song (RAVDESS), voice authentication that the two tests provided similar value. The confusion matrix used to calculate the f-score indicated that some emotions are often confused, which could all be considered closely related. Although the f-score can represent an accuracy value, these tests’ value is not accurately portrayed when not considering often confused emotions. Deciding which approach to take based on the f-score did not prove beneficial as it did not address the confused emotions. When aggregating the confusion matrix of these two tests based on selected emotions, the newly calculated utility value demonstrated a difference of 4%, indicating that the two tests may not provide a similar value as previously indicated.

This approach’s performance is dependent on the data presented to it. If the classifier is presented with incomplete or degraded data, the results obtained from the classifier will reflect that. Additionally, the grouping of emotions is not based on psychological evidence, and this was purely done to demonstrate the implementation of an aggregated confusion matrix.

The f-score offers a value that represents the classifiers’ ability to classify a class correctly. This paper demonstrates that aggregating a confusion matrix could provide more value than a single f-score in the context of classifying an emotion that could consist of a combination of emotions. This approach can similarly be applied to different combinations of classifiers for the desired effect of extracting a more accurate performance value that a selected classifier presents.

The advent of recession at the beginning of twenty-first century forced many organizations worldwide to reduce cost and to be more responsive to customer demands. Lean Manufacturing (LM) has been widely perceived by industry as an answer to these requirements because LM reduces waste without additional requirements of resources. This led to a spurt in LM research across the globe mostly through empirical and exploratory studies which resulted in a plethora of LM definitions with divergent scopes, objectives, performance indicators, tools/techniques/methodologies, and concepts/elements. The purpose of this paper is to review LM literature and report these divergent definitions, scopes, objectives, and tools/techniques/methodologies.

This paper highlights various definitions by various researchers and practitioners. A total of 209 research papers have been reviewed for the research contribution, research methodology adopted, tools/techniques/methodologies used, type of industry, author profile, country of research, and year of publication.

There are plethora of LM definitions with divergent objectives and scope. Theory verification through empirical and exploratory studies has been the focus of research in LM. Automotive industry has been the focus of LM research but LM has also been adopted by other types of industries also. One of the critical implementation factors of LM is simultaneous adoption of leanness in supply chain. LM has become an integrated system composed of highly integrated elements and a wide variety of management practices. There is lack of standard LM implementation process/framework.

The paper reviews 209 research papers for their research contribution, research methodology, author profile, type of industry, and tools/techniques/methodology used. Various characteristics of LM definitions are also reviewed.
