The purpose of this paper is to identify and analyze the challenges associated with the implementation of the concept of Maintenance 4.0 in industries.

The challenges in the implementation of Maintenance 4.0 are identified through a literature survey and interaction with professionals from the industry and academia. A structural hierarchy framework that integrates the methodologies of ISM and MICMAC is used for the analysis of Maintenance 4.0 implementation challenges. The framework establishes the interrelationship among challenges and segregates them into driving, linkage, dependent and autonomous groups.

A novel concept of Maintenance 4.0 under the aegis of Industry 4.0 is gaining appreciation worldwide. However, there are challenges in the adaptation of Maintenance 4.0 concepts among industries. The various challenges as well as their impact on the objective of implementation of Maintenance 4.0 are identified.

The practicing engineers, academicians, researchers and the concerned industries can infer from the results to improve upon the causes of such challenges and promote the implementation of Maintenance 4.0 most efficiently and effectively.

This paper is a novel, unique and first of its kind that addresses the most contemporary challenges in the implementation of Maintenance 4.0 concepts in industries.

The online purchasing behaviour of consumers has recently become a topic of increased interest and attention for marketers, policymakers, and researchers. However, due to its complex nature, this phenomenon is still in its infancy in many developing countries and needs to be paid more attention. Using the technology acceptance model (TAM), the purpose of this paper is to examine the role of utilitarian and hedonic shopping motivations, as well as the trust and privacy concerns of consumers in their online purchasing intentions, in a developing South Asian country: Pakistan.

Data were collected from 859 respondents through a self-administrated questionnaire using the non-probability convenience sampling technique and were analysed using the structural equation modelling.

The results of this study demonstrate that, more than hedonic values, trust, and privacy concerns, utilitarian values positively influence consumers’ attitudes to online purchasing. Consequently, consumers’ attitudes positively influence their online purchasing intentions. The findings indicate that Pakistani consumers buy online for goal-oriented reasons. Not surprisingly, they feel unsafe buying online due to concerns over trust and data privacy.

The findings of this study have various practical and managerial implications for electronic businesses in developing countries. This study serves as a guide for the development of effective online marketing and selling strategies.

This paper contributes to the existing literature on business to consumer e-commerce by identifying and empirically validating motivational factors and factors of concern using the TAM model. The extended TAM model, which integrates shopping motivations, trust, and privacy factors, can provide a solid theoretical foundation for consumers’ online purchasing behaviour in a developing country.

Multilevel inverters play a major role in the development of high-power industrial applications. In traditional low-level inverters (e.g. 2-level), the switching frequency is restricted and the harmonic spectrum of the system is hard to meet power requirements. Similarly, high-level inverters consist of a large number of switches, complex modulation techniques and complex hardware architecture, which results in high power loss and a significant amount of harmonic distortion. Furthermore, it is a must to ensure that every switch experiences the same stress of voltage and current. The purpose of this paper is to present an inverter topology with lower conduction and switching losses via reduced number of switches and equal voltage source-sharing technique.

Herein, the authors present a cascaded multilevel inverter having less power switches, a simple modulation technique and an equal voltage source-sharing phenomenon implementation.

The modulation technique becomes more complex when equal voltage source-sharing is to be implemented. In this study, a novel topology for the multilevel inverter with fewer switches, novel modulation technique, equal voltage source-sharing and Inductor-Capacitor-Inductor filter implementation is demonstrated to the reduce harmonic spectrum and power losses of the proposed system.

The nine-level inverter design is validated using software simulations and hardware prototype testing; the power losses of the proposed inverter design are elaborated and compared with the traditional approach.

The aim of this chapter is to examine the role of real exchange rates in the relationship between tourist arrival and economic growth in Malaysia over the period of 2000–2018. We disaggregate Malaysian tourists into six geographical regions, namely Asia, Singapore, Europe, Pacific region, Americas, and Africa. Using a non-linear autoregressive distributed lag model, we find that the appreciation of real exchange rates with positive growth of economy plays a prominent role in influencing international tourist arrivals from Singapore, other Asian countries, Pacific region, Europe, and Americas. Our study suggests that real appreciation is important in providing some insights into the effectiveness of growth-led-tourism policies. In line with this, some implications are provided at the end of this chapter.

The COVID-19 pandemic is having an unprecedented impact on schools and schoolchildren across the globe. There is still a dearth of studies that investigate this recent phenomenon in a developing country context, and this is true of Pakistan. Much of the population in Pakistan resides in rural settings and a lack of technology and of online provision of teaching for more than one year must have had huge negative impacts on students’ learning. The school dropout rate was already high in rural settings (Geven & Hasan, 2020) and, with school closures, this will likely have increased further, and cause some schoolchildren to lose interest in going back to school. However, no current data appear to exist to corroborate this. Due to the lack of available current quantitative and qualitative data, this study seeks to explore the impact of COVID-19 on schoolchildren’s education in Pakistan by examining recently published related studies. This study employs a literature review technique that gathers data to ascertain the potential overall impact on schoolchildren during the pandemic. The findings reveal that there remains a lack of detailed studies on this important topic and that urgent attention is needed from researchers to assess the scale of the impact. In addition, the review found that many children from rural communities had little to no school engagement due to technology poverty and their families being unable to support home-schooling, either due to family and/or work constraints or a lack of prior education and/or skills. Themes that emerged were that families, especially mothers, struggled to balance both caring and home-schooling duties, pupils from private schools had a better experience than those from public school backgrounds, and many of these reported that online provisions helped students develop new skills. This study may help to improve the understanding of the impact on the lost learning of schoolchildren during the pandemic by guiding practitioners as well as policymakers.

This study aims to identify enablers of belief and ethics-based marketing practices, establish relationships among the factors and present them in a hierarchical model to derive critical insights. This paper emphasizes interpretations of the in-depth interviews to decipher the market pervasiveness of the evolved model.

In-depth interviews were conducted with individuals and small groups of informed and elite respondents pursuing marketing guided explicitly by ethics and led by belief. The interview data further corroborated with the related literature contributed to specific factors. Finally, interpretive structural modeling has been implemented step by step to develop a systematic model for enablers.

This paper contributes a structural relationship of morality and ethics, strengthening faith and belief through philosophical understanding, which traverses into the actions related to societal benefits with the support of market opportunity development while bringing in value, enhancing the demand in return and establishing market pervasiveness. The crux of this paper is that the foundation of belief will reduce the hierarchy of other related factors while strengthening their interdependencies with equity to contribute to the development of the pervasiveness of the market for such organizations.

To the best of the authors’ knowledge, this is the first study exploring and examining the enablers contributing to belief and ethics-based organizations’ pervasiveness along with their interrelationships. The initial intrigue that led to the inquiry was evidence of the market pervasiveness of such organizations’ products and services across various streams.

This paper empirically examines the perceived relationship between banking sector performance and FDI inflows, thereby highlighting an underexplored area in the existing literature.

To provide evidence from the South Asian context, this study selected five economies of the same region based on the data availability. A panel dataset, collected from the internationally reliable sources for the period 1998–2017, is analyzed with the help of different econometric techniques, including pooled least squares, fixed effects, generalized least square and two stages least squares.

The results indicate a significant negative relationship between banking sector performance and FDI inflows while demonstrating a significant positive association of inflation and trade openness with FDI inflows Moreover, higher per capita income, which is one of the indicators of a growing economy, exerts a statistically significant positive impact on FDI inflows. Finally, institutional factors have not played a significant role in attracting FDI in the sampled countries.

The results demonstrate a unique outcome from the perspective of the relationship between banking sector performance and FDI inflows, and hence policymakers of the developing countries in general and South Asian countries in particular would benefit from the current study significantly.

The obtained results are original as we have provided comprehensive evidence on the relationship between FDI and banking sector performance in the SAARC context for the first time.

This paper aims to explore the viability of applying Qard Hasan as an Islamic crowdfunding financial instrument to finance micro-enterprises in Malaysia.

This is a qualitative study in which semi-structured interviews were conducted with several crowdfunding professionals concerning the application of Qard Hasan in Islamic crowdfunding. To realise the purpose of this study, the data is subjected to thematic analysis.

The finding reveals that though it is often argued that Qard Hasan is basically not a business-oriented instrument, a closer look at the framework reveals the uniqueness and flexibility of this instrument to be adopted as a viable financial instrument for crowdfunding in financing micro-enterprises in Malaysia. Although it is associated with various risks including default risk and the risk of attracting big funds. However, these risks can be managed and overcome by using FinTech mechanisms such as blockchain to carry out due diligence, monitor the project and ensure the repayment in installment.

The findings of this study may not be suitable for generalisation to all crowdfunding practices as the semi-structured interview is concentrated predominantly in Malaysia. However, it still provides valuable contributions to the Islamic crowdfunding sector in Malaysia between theory and practice.

The Qard Hasan crowdfunding framework in this study can potentially be applied to help micro-entrepreneurs reach out to financial services within their means. This framework provides means to grow the micro-enterprise sector.

Qard Hasan crowdfunding will effectively alleviate poverty by creating an avenue of opportunities for business enterprises and close the gap between the wealthy and the poor classes in society, which will eventually bring about more cooperation, more collaboration and cultivate a generous society.

In spite of the fact that Islamic crowdfunding is not a new topic in research, it lacks empirical studies, particularly qualitative analysis. As this study engages with experts in Shari’ah and crowdfunding regarding the potential application of Qard Hasan, it highlights a fresh discussion both in theory and practice.

The aim of this study is to develop a mathematical model for solar power generation system which starts with the quantification of solar resources on different characteristic surfaces at any location.

This study is based on a detailed quantitative analysis of solar potential at three different cities of Saudi Arabia: Riyadh, Mecca and Sharura. Direct normal insolation is calculated for one-axis tracking surfaces with rotation about East–West (EW) and North–South (NS) horizontal axes, a two-axes tracking surface and a fixed surface tilted at the latitude of each location and facing south. One-axis tracking parabolic trough collector with rotation about horizontal EW and NS axes, and photovoltaic systems are modeled; their performances and heat and optical losses from both systems are quantified for each location.

The findings demonstrate that energy output from the selected solar technologies is maximum and relatively stable in Sharura, whereas Mecca and Riyadh showed large variations during the course of the year.

A comparative analysis between the solar technologies would be very helpful for policy decisions to choose the best option.
