Abstract

Purpose

The numerical solution of third-order boundary value problems (BVPs) has a great importance because of their applications in fluid dynamics, aerodynamics, astrophysics, nuclear reactions, rocket science etc. The purpose of this paper is to develop two computational methods based on Hermite wavelet and Bernoulli wavelet for the solution of third-order initial/BVPs.

Design/methodology/approach

Because of the presence of singularity and the strong nonlinear nature, most of third-order BVPs do not occupy exact solution. Therefore, numerical techniques play an important role for the solution of such type of third-order BVPs. The proposed methods convert third-order BVPs into a system of algebraic equations, and on solving them, approximate solution is obtained. Finally, the numerical simulation has been done to validate the reliability and accuracy of developed methods.

Findings

This paper discussed the solution of linear, nonlinear, nonlinear singular (Emden–Fowler type) and self-adjoint singularly perturbed singular (generalized Emden–Fowler type) third-order BVPs using wavelets. A comparison of the results of proposed methods with the results of existing methods has been given. The proposed methods give the accuracy up to 19 decimal places as the resolution level is increased.

Originality/value

This paper is one of the first in the literature that investigates the solution of third-order Emden–Fowler-type equations using Bernoulli and Hermite wavelets. This paper also discusses the error bounds of the proposed methods for the stability of approximate solutions.

Abstract

Purpose

The role of insurance is a backbone for consumers to secure their future. It is important to know where to invest and what are the benefits. Therefore, for the Muslim segment, Islamic insurance system provides Riba (interest)-free environment where consumers invest their money and recover their losses according to sharia. This paper aims to examine the determinants that influence purchase intention of consumers toward Islamic insurance (Takaful) adoption in Pakistan with the help of the modified theory of planned behavior (TPB).

Design/methodology/approach

The authors added four specific variables related to Islamic sharia compliance in the conventional form of the TPB. The relationship among the variables is assessed by using partial least squares structural equation modeling, while the data are collected from 305 respondents.

Findings

The results suggest that attitude, subjective norm and perceived behavioral control are strong predictors of an Islamic insurance adoption in Pakistan. Moreover, factors such as compatibility, relative advantage and awareness have positive and significant impacts on takaful participation. A negative but insignificant relation is found between perceived risk and intention.

Practical implications

This paper provides insight for understanding the factors that lead to consumers' purchase intention of Islamic insurance.

Originality/value

This paper makes a unique contribution to the literature with reference to Pakistan, being a pioneering attempt to investigate the factors of Islamic insurance adoption by modifying the TPB and applying more rigorous statistical techniques like confirmatory factor analysis (CFA) and partial least square structural equation modeling.

Abstract

Purpose

Since passenger safety is critical, aviation maintenance is essential. Aviation maintenance management is changing due to Industry 4.0 (I4.0). According to earlier research, I4.0 technologies improve aircraft manufacturing efficiency and responsiveness through automation, predictive maintenance and process self-optimization. Thus, this study examines I4.0 research and aircraft maintenance's potential interaction.

Design/methodology/approach

Using a text-mining methodology, this paper looks at the state of the art in aviation maintenance research in the I4.0 era. We used the topic modeling approach and Latent Dirichlet Allocation (LDA) technique to analyze the abstracts and indexed keywords of 929 research articles on the intersection of aviation maintenance and I4.0, subsequently clustering them into eight topics.

Findings

We have mapped out the emerging research trends at the intersection of “aviation maintenance” and “I4.0 technologies”, and presented suggestions for theoretical frameworks, applied frameworks and future lines of inquiry. This paper makes a theoretical contribution to the systematization of literature on I4.0 technologies in aviation maintenance. It provides valuable insight for managers by exploring the implications and opportunities that arise in light of recent innovations brought by I4.0 in aviation maintenance.

Originality/value

This study focuses on the use of Industry 4.0 technologies in aircraft maintenance processes, contributing to the growing research on digital technology in maintenance and maintenance, repair and overhaul (MRO). Furthermore, the study's analysis of the LDA topic model provides valuable insights for future research on using I4.0 technologies to investigate specific areas of application in the context of digital maintenance.

Abstract

Purpose

Despite noted instances of organizational cronyism in public sector Higher Educational Institutions (HEIs), there is a lack of empirical evidence on its detrimental outcomes. The present investigation tested the impact of organizational cronyism on knowledge hiding via the mediating role of moral disengagement and moderating role of egoistic climate.

Design/methodology/approach

A multi-stage random sample was drawn from the 312 teaching faculty working in HEIs of Lahore, Pakistan in three waves. M-plus was used to validate a longitudinal moderated mediation model based on Structural Equation Modeling.

Findings

The results showed that organizational cronyism leads to knowledge hiding. In addition, it was substantiated that moral disengagement acts as a mediator in the relationship between organizational cronyism and knowledge hiding. The strengthening impact of an egoistic climate was found in the direct and indirect association between organizational cronyism, moral disengagement, and knowledge hiding.

Originality/value

There is a dearth of research on the consequences of organizational cronyism and the understanding of the factors that underlie this association is limited. This research has bridged this gap by investigating the role of moral disengagement and egoistic climate in linking organizational cronyism and knowledge-hiding by building on social exchange and social cognitive theory.

Abstract

Purpose

The research focused on analysing a unique type of heat exchanger that uses swirling air flow over heated tubes. This heat exchanger includes a round baffle plate with holes and opposite-oriented trapezoidal air deflectors attached at different angles. The deflectors are spaced at various distances, and the tubes are arranged in a circular pattern while maintaining a constant heat flux.

Design/methodology/approach

This setup is housed inside a circular duct with airflow in the longitudinal direction. The study examined the impact of different inclination angles and pitch ratios on the performance of the heat exchanger within a specific range of Reynolds numbers.

Findings

The findings revealed that the angle of inclination significantly affected the flow velocity, with higher angles resulting in increased velocity. The heat transfer performance was best at lower inclination angles and pitch ratios. Flow resistance decreased with increasing angle of inclination and pitch ratio.

Originality/value

The average thermal enhancement factor decreased with higher inclination angles, with the maximum value observed as 0.94 at a pitch ratio of 1 at an angle of 30°.

Abstract

Purpose

This study aims to address a leading challenge of confusion about the concept of takāful confronted by existing and potential consumers of the insurance industry. There are multiple sources of confusion, including the lack of consensus among religious scholars to implement a standardized business model of takāful, the lack of knowledge or awareness and the lack of skilled or trained personnel, which prevent existing and potential consumers from adopting takāful products or services. The fundamental concept of takāful is introduced mainly to fulfill the religious, social and economic needs of Muslims. Thus, the choice of takāful activates the religious, cultural, family and tradition values of individuals. Hence, the primary purpose of this study is to determine the impact of tradition value and stimulation value on consumer adoption of takāful services. Further, the scope of this study is extended to establish the mediating role of religiosity and moderating role of confusion on the association between tradition value and consumer adoption of takāful services.

Design/methodology/approach

This study follows quantitative research methods and a cross-sectional approach for data collection. Thus, the sample is collected from 768 respondents belongs to rural and urban areas by using a close-ended questionnaire. The mediation and moderation analysis are performed by using Andrew F. Hayes process Models-4 and −5.

Findings

The result reveals that religiosity mediates and confusion moderates the relationship of tradition value and consumer adoption of takāful. However, the tradition value shows a negative effect on consumer adoption of takāful. Moreover, the confusion negatively moderates the association between tradition value and consumer adoption of takāful. Finally, the stimulation value also reflects a negative effect on consumer adoption of takāful services.

Originality/value

The findings of this study shed novel insights into the existing literature of takāful and basic human values. The outcomes of stimulation values contradict with the findings of Wang et al. (2008). The result of mediation analysis reveals that religiosity plays a vital role in activating the goals of tradition value, which motivates consumers to adopt takāful services. The present study is useful for takāful operators to understand the value priorities of prospect clients belong to rural and urban areas.

Abstract

Purpose

This study aims to delineate the fast-growing path of human resource management (HRM) research with a sustainable orientation and resolve confusion over the differences and interdependences of the various approaches that have emerged: green human resource management (GHRM), sustainable human resource management (Sustainable HRM), and socially responsible human resource management (SR-HRM).

Design/methodology/approach

In this study, bibliometrics and science mapping were used to analyze the field's conceptual structure based on 587 related documents extracted from the ISI Web of Science database. Co-word analysis with SciMAT software enabled the authors to map the main themes studied and identify evolution, importance, and relevance.

Findings

SR-HRM is the least developed of the three approaches analyzed and has been overlooked by the journals that publish the most work in the field of HR. The authors identify a lack of sustainability-related HRM studies on higher education and an ongoing need both to explore the role of culture in GHRM implementation and to explain further the potential non-green behavioral outcomes that can result from GHRM's use.

Practical implications

This study demonstrates how human resource factors are key to managing challenges such as aging workforce, unstable employment relationships, implementation of green supply chain management, and Industry 4.0.

Originality/value

This study explores in detail the interrelations among various emerging sustainable human resource approaches and subtopics derived from the interrelations to reveal hotspots, dilemmas, paradoxes, and research gaps.
