This research aims to study a broad range of sustainability aspects and develop a set of indicators with their subjective relevance to each of the sustainability dimensions that will help to improve the sustainability level of the water system of Nur-Sultan (Kazakhstan).

The broader list of indicators (which were identified through a thorough review of the literature) was assessed by water-related industry professionals and experts who were asked to assess the compliance of suggested indicators to five criteria of sustainability using a Likert scale.

It was found that the highest-ranked indicators across all five categories were mainly related to the chemical and physical quality of water, followed by availability of individual water meters as well as water supply tariffs' adjustment to users' income, and issues of ageing infrastructure. The lowest-ranked indicators among all categories were mainly related to investments into research and development, water management and awareness, feedback systems and flexibility. The least ranked indicators are seen to be more related to the scenarios when basic needs are covered and the stakeholders have extra time and resources for advancing the levels of water infrastructure sustainability.

The ranked and categorized indicators can be used as a powerful decision-making tool to improve the sustainability of the water system of Nur-Sultan or any other city in a developing country.

By conducting this study, it was aimed to address the aforementioned gap in the field in terms of running a wider scope assessment of indicators rather than looking at conventional environmental and socio-economic aspects. This provides novelty to the study, especially in the context of developing countries that need more guidance in terms of sustainable development of the water-related infrastructure.

Purpose – This chapter analyses the socio-economic development of the Muslim community in Kelantan through the establishment of the Bazar Wakaf Rakyat (People’s Waqf Bazar).

Nutrition labels provide a cost-effective method of conveying nutrition information to consumers. This study aimed to assess the use of nutrition facts panels, knowledge of traffic light labelling (TLL) and perceived healthiness of food items using TLL among consumers.

A web-based cross-sectional study was conducted among adults in the United Arab Emirates (UAE) (n = 1,322). TLL knowledge score was derived for each participant. Conjoint analysis was used to calculate the utilities and relative importance of the perceived healthiness scores for four attributes (fat, saturated fat, total sugar, salt) at the aggregate level.

Participants had a positive attitude towards TLL but were less familiar with TLL than the nutrition facts panel (47.4 vs 85.8%). The mean TLL knowledge score was 3.6 out of 7 (51.6%). Younger age, higher education, higher income, and health-related qualifications were associated with higher scores. Conjoint analysis showed that participants tend to choose products with greener labels, especially for sugars (80.1%) and avoid red labels for fats. Sugars had the highest percentage value of relative importance compared to the other attributes (27.1%).

The study outcomes offer valuable insights into the extent of consumer awareness, comprehension and utilization of nutrition facts panels in the UAE. These findings contribute essential knowledge for a deeper understanding of the impact of nutrition labels on consumer behaviour and decision-making in the region.

This chapter provides a literature review on the topic of emotional intelligence (EI) in the workplace. Quantitative methods were used, with surveys sent to a predetermined sample and processed with the SPSS statistical package. The overall aim of the study was to investigate the effect of EI based on self-awareness, self-management, empathy, and relationship management on work engagement in a public university. One hundred eight professors at the public university. The data for this study were collected by means of a questionnaire. In total, there are 23 questions on a Likert scale. Cronbach's alpha showed that the reliability of the instrument was higher than 0.763. In light of the data, it has been shown that there is correlation between self-awareness, self-management, relationship management, empathy with both work engagement and job satisfaction. Furthermore, the results show that EI is significantly related to both university loyalty and job happiness. Only a conditional link was created between professors' achievements and the success of the public university.

Existing literature is still lacking field works that reflect the implications and applications of blockchain in supply chain management. This paper aims to explore the role of blockchain technology in improving the performance of maritime shipping and develop a model to enhance blockchain applicability.

Qualitative data were collected through 28 semi-structured interviews from several supply chain actors in the Middle East and were analyzed based on a thematic analysis approach using NVivo software.

An emerging model for improving the performance of the maritime shipping industry through blockchain technology has been developed. The findings suggest that there are transparency and process efficiency–related improvements as an outcome of Blockchain implementation in the maritime shipping industry.

As shipping industry is largely fragmented, small players find it difficult to achieve great benefits such as those achieved by larger players in the sector. The authors’ model provides guidance for the implementation of Blockchain.

To the best of the authors’ knowledge, this is one of the first scholarly works to investigate Blockchain applicability in shipping industry in the Middle East. The lack of a universal standard is a considerable challenge which is still hindering the development of blockchain applications that integrate the different actors.

This study aims to scrutinise the impact of fibre length and its composition on the tribological attributes of oil palm fibre (OPF) polymeric composite as an alternative brake friction material.

Fabrication of the sample was conducted by using a hot-compression method. The tribological test was carried out by deploying a ball-on-disk tribometer. Analysis of the data was then done by using the Taguchi approach as well as analysis of variance.

The results indicated that all design variables (fibre composition, length and treatment) are not statistically significant, as all p-values are greater than 0.05. Remarkably, irrespective of the fibre treatment, the wear rate and coefficient of friction (COF) distribution suggested that a smaller fibre length with a high fibre composition might enhance the composite’s tribological performance with COF of 0.4 and wear rate below than 1 × 10^–9 mm³/Nm. The predominant wear mechanisms were identified as micro-cracks, fine grooves and fibre debonding.

In this study, all-inclusive scrutiny needs to be carried out for further exploration.

The main contribution and novelty of this study are opening a new perspective on the formulation of new substances from bio-based material (i.e. OPF) that possess superior tribological characteristics for friction-based applications.

The purpose of the study is to analytically as well as numerically investigate the weight of throughflow on the onset of Casson nanofluid layer in a permeable matrix. This study examines both the marginal and over stable kind of convective movement in the system.

A double-phase model is used for Casson nanofluid, which integrates the impacts of thermophoresis and Brownian wave, whereas for flow in the porous matrix the altered Darcy model is occupied under the statement that nanoparticle flux is disappear on the boundaries. The resultant eigenvalue problem is resolved analytically as well as numerically with the help of Galerkin process with the Casson nanofluid Rayleigh–Darcy number as the eigenvalue.

The findings revealed that the throughflow factor postpones the arrival of convective flow and reduces the extent of convective cells, whereas the Casson factor, the Casson nanoparticle Rayleigh–Darcy number and the reformed diffusivity ratio promote convective motion and also decrease the extent of convective cells.

Controlling the convective movement in heat transfer systems that generate high heat flux is a real mechanical challenge. The proposed framework proved that the use of throughflow is one of the most important ways to control the convective movement in Casson nanofluid. To the best of the authors’ knowledge, no inspection has been established in the literature that studies the outcome of throughflow on the Casson nanofluid convective flow in a porous medium layer. However, the convective flow of Casson nanofluid finds many applications in improving heat transmission and energy efficiency in a range of thermal systems, such as the cooling of heat-generating elements in electronic devices, heat exchangers, pharmaceutical practices and hybrid-powered engines, where throughflow can play a significant role in controlling the convective motion.

Finding an efficient way for enhancing brand reputation by using social media among customers and business partners has long been the main purpose of every business. However, due to micro and macro changes in the business field, strategies to find a way to improve brand reputation with business partners and customers have altered from transaction marketing to newer approaches such as employing a social media platform. However, not all brands make use of social media to enhance their reputation. The present study uses Apple as an example of the one of the best known brands which does not benefit from social media platforms as to the degree expected.

The study aims to examine the connection between practices of total quality management (TQM) and sustainability in Malaysia food and beverages companies (FBC). Continuous process improvement, benchmarking, management leadership, human resources management, quality assurance, service design and information and analysis as TQM practices are considered and their relationship, respectively, with sustainable performance.

A survey questionnaire is administered to gather responses from 303 FBC, while 98 responses are useable and subsequently analysed using partial least squares structural equation modelling.

The results reveal that effective implementation of continuous process improvement, benchmarking, quality assurance, service design and information and analysis have positive and significant effect on sustainability.

The scope of the present study was limited to FBC in Malaysia, and a cross-sectional design was employed to examine the hypothesized relationships at a single point in time.

The proposed and developed model of this study can be employed by policy and decision makers in the industry. This model can be considered by practitioners in the industry to implement critical policies in the future.

The premises of the institutional and contingency theory are supported by re-affirming the importance of contingencies and institutions for any successful strategic practices to enhance sustainable performance by implementing TQM.

A family takaful certificate is subscribed by a takaful participant for the purpose of preparing financial support for his dependants after his death. The takaful benefits could then be made payable to a nominee named as the beneficiary under conditional hibah (gift). In this respect, the participant is free to decide to whom the benefits are to be given since the law is silent as to the criteria of the beneficiary. This situation gives rise to the issue on whether such a practice fulfils the objectives of Sharīʿah, especially when the nominated beneficiary is not the sole dependant of the deceased participant. Therefore, this research aims to evaluate the status of family takaful benefits, analyse the rules of conditional hibah from the Sharīʿah perspective and propose solutions whenever necessary. The research adopts doctrinal analysis by examining existing primary and secondary materials including statutory provisions and other legal and non-legal literatures. The study predicates that the application of conditional hibah to the whole benefits does not reflect the objectives of Sharīʿah if determination on the status of the benefits is solely based on the nomination made by the participant. It is observed that takaful benefits payable from the Participant’s Account should be considered as the deceased’s estate and must be distributed according to fara’id or Islamic law of inheritance. Conversely, the sum covered payable from the Participant’s Special Account may be paid to the deceased’s dependants whose criteria are determined by the Sharīʿah Advisory Council as the highest authority in Islamic financial matters.
