This paper aims to present stability of a three-layered journal bearing considering magnitude of the layers’ thicknesses and viscosities with slip/partial slip on the bearing surface.

Modified Reynolds equation based on one-dimensional analysis is derived for a three-layered journal bearing with slip/partial slip. Dynamic coefficients are derived based on infinitesimal perturbation method. Linearized stability analysis is presented taking into account slip/partial slip on bearing surface; thicknesses and viscosities of bearing surface layer; and core layer and journal surface layer.

Results of threshold speed and critical whirl frequency ratio coefficients (C_ω, C_Ω), stiffness (K_ij for i = x,y) and damping (B_ij for i = x, y) coefficients and threshold speed (ω_s) and critical whirl frequency ratio (Ω_s) are presented. The bearing surface is analyzed for slip (total surface with slip) and partial slip (partial surface with slip). The slip-on bearing surface reduces stability, while partial slip improves bearing stability. The threshold speed coefficient (C_ω) decreases with slip on bearing surface. The threshold speed (ω_s) and critical whirl frequency ratio (Ω_s) are influenced by the variation of threshold speed coefficient (C_ω) and critical whirl frequency ratio coefficient (C_Ω), respectively. A three-layered journal bearing with partial slip and thick high viscosity bearing surface layer results in higher threshold speed coefficient and has a potential to improve stability of journal bearing. The analyses indicate that optimal angular extent of partial slip region (θ_s) enhances the stability of journal bearing.

The paper presents parametric study of stability coefficients (C_ω and C_Ω) and evaluation of threshold speed (ω_s) and critical whirl frequency ratio (Ω_s) of a three-layered journal bearing with slip/partial slip.

This study aims to analyse the mechanism of trust instrument from a Shariah point of view. Analysis of the mechanism would determine the extent to which its implementation can resolve estate planning issues such as frozen estate and the issue of naming beneficiaries under the age of 18.

This is a qualitative study method through library research. To explore the mechanism of trust instrument, an in-depth interview with five participants using purposive sampling and analyses of documents were used. The selection of this sample allows the researcher to obtain specific data in their field of expertise. Therefore, two officers from the Trust Administration Department of Amanah Raya Berhad (ARB) and three Shariah advisors from ARB (MPS ARB) were interviewed to find out the mechanism of trust instrument from the Shariah perspective. The researcher also referred to the trust deed documents, ARB company policies, field case studies such nomination cases and trust accounts, articles and court cases.

The trust instrument meets Shariah requirements even though it is based entirely on the Civil Law. The comprehensive and flexible features of trust deeds can help donors to plan systematically during their lifetime.

This study only focuses on the trust instruments that are currently being implemented in the ARB. Five trust products were analysed to achieve the objectives of the study, namely, the Normal Trust, Safecare and Safecare Premium, Takaful Care, Hibah (literally “gift”) as well as Trust and Declaration of Hibah.

The implementation of trust instrument at an early stage can ensure the property is well managed through a trust deed, guarantee the life of the beloved heirs after the death of the donor and prevent the property from being frozen.

This study comprehensively describes the trust instrument from the Shariah perspective and its implementation mechanism in the industry.

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.

The purpose of this study is to examine the management of cash waqf fund generation through the implementation of istibdal in Kedah.

The data are obtained through literature and empirical data. The authors first review the literature on the importance of waqf fundraising, the implementation factors of istibdal waqf and the relevance of istibdal method as a waqf fund generation medium to understand the extent to which the scholarly articles have discussed these topics. Furthermore, the authors conducted face-to-face interviews with two Kedah Islamic Religious Council (Majlis Agama Islam Kedah [MAIK]) officers, who were directly involved in the affairs of istibdal waqf to obtain holistic information regarding implementing istibdal waqf properties in Kedah. As a result, several themes are defined from the interview data before being analysed based on the content analysis method.

The results of the study show two istibdal implementation processes outlined by the Kedah Islamic Religious Council (MAIK), namely, the istibdal implementation process for waqf land registered title deed, and waqf land registered as reserve certificate for religious use like mosque and cemetery. The results also showed three factors in implementing istibdal in Kedah: the acquisition of waqf land by the state authority (PBN), istibdal application by the state education department (JPN) and istibdal application by the mosque committee. Out of eight cases of istibdal implementation, four have generated cash funds for MAIK through investment methods from the sale of waqf lands and rental of replaced shophouses that are able to cover the expenses of managing waqf properties in Kedah. Several suggestions are also recommended for MAIK to improve its istibdal policy, thus enabling the institution to generate cash waqf funds at the maximum rate.

This study only focused on the implementation factors and the generation of cash waqf funds through istibdal in Kedah, while it can be expanded to other states like Terengganu, Kelantan and Penang. Furthermore, this study only interviewed officers who manage matters related to the affairs of waqf properties, as the session can actually be extended to other respondents, such as those specialising in cash fund generation investments and others.

This study proposed some improvements to the policy and guidelines of istibdal waqf property to MAIK after a few shortcomings were identified throughout this study. If improved, these proposals will have a significant impact, especially on the waqf properties involved in the implementation of istibdal, where it has the potential to bring cash generation and ensure the constant economic value of waqf properties.

This study has a tremendous impact on society, in which their areas have cash waqf funds that can be developed. It can benefit the needy and increase funds for the welfare expenditure of Muslims through rental income, investment and development. Progress on waqf property provides a high indication of the efficiency of an organisation in managing the waqf property. Thus, the public, especially the rich, is motivated to fulfil their charitable practices through waqf mechanism and share their wealth with the needy.

This study contributes to comprehensive field data on the implementation factors and generation of cash waqf funds through the implementation of istibdal in Kedah. The results of this study are significant to be used by waqf property management.

This paper aims to examine the current practice in Singapore regarding an inheritance issue: disposal of the residual net estate to the bayt al-māl, which is identified as the Islamic Religious Council of Singapore (Majlis Ugama Islam Singapura, MUIS). The issue arises when the deceased leaves farḍ (fixed-share) heir(s) and/or dhawū al-arḥām (outer family members) but there is no ʿaṣabah (agnatic residuary heir by blood). Farḍ legal heirs are those beneficiaries for whom the Qurʾān prescribes inheritance of a pre-determined share. Disposal of the residual net estate to the bayt al-māl results in a reduction in the share due to the farḍ legal heir or worse, a total loss to the dhawū al-arḥām legal heirs.

A qualitative approach based on library and case study research has been adopted to elaborate practices that fall under the purview of the Administration of Muslim Law Acts (AMLA), Chapter 3.

The current practice seems biased against, especially, women and spouses. It creates high dissatisfaction in the community, especially those affected by such practices. This paper elaborates on the practice of residual net estate distribution in Singapore and the contemporary practices of the four Sunni madh-habs – the Ḥanafī, Mālikī, Shāfiʿī and Ḥanbalī jurisprudential schools – in other countries.

In Singapore, Muslim law is defined and implemented by the civil court, not the Syariah Court or MUIS. The recommendation to change from the current classical practice by the Syariah Court and MUIS to the contemporary practice that is relevant to today’s context lies with the civil court and Government of Singapore. The choice for the Syariah Court and MUIS to adopt the contemporary practice as per Ḥanafī School by rule of the court or the government is beyond this research. Zayd ibn Thābit, Caliph Abū Bakr and a small number of companions held the view that the residue net estate asset must go to the bayt al-māl, the current classical practice. The contemporary practice adopted by Sayyidina ʿUthmān ibn ʿAffān, Jābir ibn Zayd and majority of the companions’ view, is not in favour of the residue net estate asset to go to the bayt al-māl; rather they view that it must be returned to the legal heirs.

Awareness in the community in the current controversial practice in Singapore when the residue net estate through the farāʾiḍ law was giving to bayt al-māl instead of returning to farḍ or dhawū al-arḥām in the absence of the ʿaṣabah legal heir as stated in the Inheritance Certificate issued by Syariah Court.

To understand the contemporary Muslim law and the practical and just application in today’s Singapore context as supported by the AMLA, Chapter 3.

This is the first study that challenges the current practice by the Syariah Court and MUIS in Singapore, thereby endeavouring to restore justice to the community.

This paper aims to analyse the implementation of istibdal waqf property in several states of Peninsular Malaysia. To achieve this objective, this study identified the amount of waqf property ‘am (general) and waqf property khas (special) which were involved in the process of istibdal in each state, the factors that have caused the istibdal to be implemented, the rate of istibdal involved for each lot of waqf lands and the type of property replacement performed.

This study used the qualitative method, whereby the researchers had collected secondary data consisting of documents related to waqf from the State Islamic Religious Council (MAIN). The type of documents obtained were public records. The data collected were analysed using the content analysis techniques.

The results showed that there are several factors involved in the implementation of istibdal, namely, the acquisition of waqf land by the State Authority, applications by external parties for a particular interest and the initiatives taken by the MAIN on waqf property which is problematic and uneconomical to generate waqf fund. This study also found some Shariah and management issues, which were identified in the implementations of istibdal, whereas some cases of istibdal were only carried out on a small part of the waqf lands and there were also cases of the implementation of istibdal which have not been replaced with fixed assets as authorised by the istibdal parameter. This study suggests some improvements to the issues identified in the implementation of istibdal for waqf managers in Malaysia.

The limitation of this study is that it analyses only the documents that record the implementation of istibdal in the states managed by MAIN. Thus, the analysis performed was limited to the documents obtained without involving empirical data.

This study suggests some improvements to the implementation of istibdal waqf in the states studied. Therefore, these recommendations can be used by waqf property managers to improve the process of implementing waqf property istibdal so that it can be used to its maximum potential.

If the recommendations in this study can be implemented, the Muslim community will benefit greatly from the waqf property because it is being developed through the method of istibdal. This impact can increase the confidence of the Muslim community towards MAIN in managing waqf property and encouraging the Muslim community to contribute to waqf property for the welfare of the ummah.

This study involved data on a larger waqf istibdal implementations that involved several states in Peninsular Malaysia, which to the best of the authors’ knowledge, the analysis involving such large research data have not been implemented before.

This study aims to explore the challenges of getting halal certification for restaurants in north-eastern Thailand.

Qualitative research approach was adopted to analyse the collected data. The research procedures and the interview questions were examined by the Ethics Committee for Research involving human subjects. In total, 10 restaurant owners were interviewed. Then, the interviews were transcribed, coded and grouped by using thematic analysis while the ATLAS ti. software was used for qualitative data analysis. The theme was finalised by three intercoder agreements.

The three challenges of obtaining halal certification among restaurants in north-eastern Thailand were the complicated process of getting halal certification, lack of restaurant owner commitment and high halal certification fee.

The number of halal-certified restaurants are limited. Some restaurants refused to renew halal status but their information is still displayed on the halal authority website. Not only the number of restaurants but also time-limited. Further, a quantitative phase for prioritising was suggested.

The study can be beneficial to the halal authority and business holders as the two main stakeholders. The findings can be used to plan or develop halal strategies to increase the quality of halal restaurants. As informants mentioned common challenges, the findings could be applied as guidelines for a new business holder keen on halal implementation.

This research demonstrated the challenges of halal certification in a non-Muslim country, focussing on the north-eastern region of Thailand. The findings will add value to a potential business area. Therefore, the highlighted challenges could provide a novelty and be useful for Muslim marketing.

Impulsive buyers are a dream segment for retailers and marketers. Stimulants in the retail environment and cognitive aspects evoke a sudden urge the acquisition of products spontaneously. This paper aims to examine key cognitive aspects of impulsive buying behaviour and purchase regret in an online context.

An online survey was conducted to collect the data of 317 online consumers with the help of a convenience sampling technique. The structural equation modelling technique was carried out to establish the validity and reliability of measures and examine the proposed relational paths.

The study results suggest that cognitive aspects recede impulsive buying, resulting in purchase regret. The empirical findings on the impulsive buying behaviour and purchase regret to yield several important implications, including developing marketing strategies and policies to evoke the intentions for impulsive buying behaviour, consumer innovation and balancing the feelings of regret.

The study also provides some significant contributions to the literature on online impulse buying and its related paradigms.

This study mainly attempted to determine the precursors of online impulse buying and purchase regret from the perspective of hedonic and experiential consumption motivation and consumer innovation. Getting reflections from cognitive dissonance theory and the post purchase evaluation, a theoretical model was developed and empirically tested for impulsive online buyers.

This study aims to examine the concept of brand equity and willingness to buy second-hand products in the automobile context. The customer-based brand equity model is used as a theoretical lens to examine after-sales services, brand credibility and brand loyalty as drivers of brand equity and willingness to buy the second-hand product.

A survey questionnaire based on convenience sampling is used to collect the data from the car owners. A total of 433 survey responses were used to empirically test the measures and propositions by using structural equation modeling (SEM).

The findings suggest that after-sales services are a key factor in developing brand credibility and brand loyalty. Results are also in support of the positive and significant impact of brand credibility and brand loyalty on brand equity and willingness to buy second-hand products.

Brand equity represents a differential response and preference to marketing efforts that a product obtains as a result of its brand identification. Although practitioners are actively engaged to position themselves as a unique, attractive and strong brand, little is known about the equity of the brand in the case of second-hand products. This study provides an alternate branding view to the academic scholars and to the marketing manager as this study explicitly probes into the effect of after-sales services in developing brand credibility, brand loyalty, brand equity and wiliness to buy second-hand product as an outcome.

Knowledge hoarding is an emerging issue among multiracial employees engaged in public sector higher educational institutes (HEIs) of Islamabad, Pakistan. By considering knowledge-sharing barriers, this study aims to examine the knowledge sharing behavior (KSB) of ethnically diverse public sector staff in perspective of well-known theory of planned behavior (TPB).

It is a cross-sectional survey study, and it has used a self-administered questionnaire for data collection. With proportionate stratified random sampling technique, 273 nonacademic employees associated in 15 public sector HEIs of Islamabad have recorded their responses. Structural equation modeling was employed for empirical hypotheses testing.

Results stated significant and positive effect of cultural diversity management, interpersonal trust and knowledge technology on KSB. Moreover, knowledge-sharing attitude (KSA) fully mediated the relationship between cultural diversity management and KSB and between interpersonal trust and KSB; whereas KSA partially mediated the relationship between knowledge technology and KSB. Moreover, proposed model has explained 45% variation in endogenous construct.

Current study contributes to the present literature by investigating the antecedents of knowledge-sharing behavior of multicultural nonacademic staff engaged in public sector HEIs of capital city of Pakistan. Enriching the top management thoughts about problems of diverse workforce, the researcher has explored a noticeable lack in elucidation of such connection. Moreover, formation of knowledge-sharing behavior specifically on ethnic-based diverse employees made a significant addition in existing literature.

The present research aids academic leadership in designing policies and strategies to enhance knowledge sharing among public sector employees and to create a supportive knowledge-sharing culture.

This study fills the empirical gap in literature by exploring the antecedents and their effect on KSB of nonacademic employees of Islamabad, Pakistan. Moreover, assessing the mediation effect of KSA between CDM and KSB on multicultural public sector employees is another novel inclusion in literature.
