Abstract

Purpose

This paper aims to investigates a novel design of a modular moving magnet linear oscillating actuator (MMM-LOA) with the capability of coupling modules, based on their application and space requirements.

Design/methodology/approach

Proposed design comprised of modules, and modules are separated by using nonmagnetic materials. Movable part of the proposed design of LOA is composed of permanent magnets (PMs) having axial magnetization direction and tubular structure. Stator of the proposed design is composed of one coil individually in a module. Dimensions of the design parameters are optimized through parametric analysis using COMSOL Multi Physics software. This design is analyzed up to three modules and their response in term of electromagnetic (EM) force and stroke are presented. Influence of adding modules is analyzed for both directions of direct current (DC) and alternating input loadings.

Findings

Proposed LOA shows linear increase in magnitude of EM force by adding modules. Motor constant of the investigated LOA is 264 N/A and EM force per PM mass is 452.389 N/kg, that shows significant improvement. Moreover, proposed LOA operates in feasible region of stroke for compressor application. Furthermore, this design uses axially magnetized PMs which are low cost and available in compact tubular structure.

Originality/value

Proposed LOA shows the influence of adding modules and its effect in term of EM force is analyzed for DC and alternating current (AC). Moreover, overall performance and structural topology is compared with state-of-the-art designs of LOA. Improvement with regard of motor constant and EM force per PM mass shows originality and scope of this paper.

Abstract

This chapter The Grass Is Greener Where You Water It! delves deeper into explicating Employee Green Behaviour (EGB), which outlines the eco-friendly behaviours practiced by employees. The section provides a more thorough explanation of EGB, including its origins, theoretical foundations, and practical applications in a social and physical environment to create environmentally conscious workplaces. The in-role and extra-role of EGB are discussed to strengthen its execution, and its significance considering the present ecological exigency. This chapter outlines the five-features-hierarchical framework for EGB: Sustainability Initiatives, Non-Harmful Action, Resource Conservation, Peer Influence, and Individual Commitment. The environmental history, ecosystems, and biodiversity and their interaction with humans from the ancient period to the present day are provided. The later unit explores organizational plans to encourage EGB, focussing on the role of HR policies, practices, and systems in nurturing the culture of sustainability within organizations. This chapter reviews current studies on EGB, emphasizing the role of employee engagement, transformational environmental leadership, and corporate culture in promoting green practices. It contributes to the academic literature by analyzing EGB, its relevance, and the effects it can have on organizations and society. It is a great tool for academics, government officials, and business heads to make workplaces environmentally friendly.

Abstract

Purpose

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.

Design/methodology/approach

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

Findings

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.

Originality/value

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.

This study aims to investigate the claim that there is no coherent and homogeneous body of concepts and practices that can be classified as “Islamic accounting”.

Abstract

Purpose

This study aims to investigate the claim that there is no coherent and homogeneous body of concepts and practices that can be classified as “Islamic accounting”.

Design/methodology/approach

The study focuses specifically on Islamic accounting and uses a qualitative historical documentary analysis methodology to study an original manuscript from the 14th century.

Findings

The analysis of the manuscript argues that religious accounting can be seen as a value-based system for achieving social good and that in the context of Islamic accounting, it can be conceptualised as a coherent body of ideas and practices.

Originality/value

Firstly, the study conceptualises Islamic accounting as a homogeneous discipline with its own knowledge, concepts and practices. Secondly, it contributes to current accounting literature by examining an ancient manuscript from the 14th century, which serves as a foundation for understanding the Islamic accounting system within the context of accounting, religion and spirituality. The paper further contributes by arguing that this conceptualisation of religious accounting as a value-based approach enables its practitioners to evaluate their own accountabilities in delivering on socioeconomic objectives related to inter-human/environmental, social and financial transactions within the context of religious accounting practices.

Abstract

Purpose

The face value of nonowner-occupied real estate and business fixed assets is excluded from Zakah, according to most Fiqh scholars who argue that it has not been explicitly ordered during the lifetime of Prophet Muhammad (sas). This study aims to test the hypothesis that the role of these properties in the early Islamic economy was insignificant and, therefore, differed from today.

Design/methodology/approach

A qualitative historical analysis of primary Islamic sources and narrations from early Muslim historiography has been conducted to understand real estate sales and rent, construction costs and the number and size of houses owned by the Sahabah. In addition, inheritance reports and land gift records have been examined to obtain relevant information about the value of real estate. As for business fixed assets, the type, number and wealth of craftspeople as well as their tools have been analyzed to reveal their significance in comparison with today.

Findings

The findings of this study confirm the hypothesis that real estate for investment purposes and business fixed assets were quasi-non-existent during the lifetime of the Prophet (sas) and, therefore, irrelevant from a Zakah perspective.

Originality/value

This study intends to be a catalyst for the reconsideration of Zakah on these items of wealth and contributes to the Fiqhi discourse.

Abstract

Purpose

Abusive supervision (AS) provides insights into the darker aspects of leadership behavior and its effects on employees. Understanding and addressing AS can contribute to creating healthier work environments and promoting employee well-being. The effect of abusive leadership (AS) on counterproductive work behaviors (CWB) in nursing staff is examined through the theoretical lens of the social exchange theory.

Design/methodology/approach

Data were collected from 302 nursing staff working at public and private hospitals through a self-administered questionnaire. Measurement scales were adapted from the literature and the data were tested for validity and reliability before performing hypotheses testing through structural equation modeling in SmartPLS 4.0.

Findings

AS positively affects CWB, and psychological contract breach mediates this relationship. However, employees with high Islamic work ethics (IWE) are less concerned with supervisors' dysfunctional behaviors and pay less attention to them; thus, IWE buffers the effect of AS on CWBs.

Originality/value

A positive and supportive organizational climate is crucial for attracting and retaining skilled healthcare professionals. When healthcare professionals are subjected to abusive behaviors, their ability to share knowledge, adopt safety protocols and provide the best patient care may be hampered. Therefore, addressing AS in hospitals is vital to promoting a positive work environment, enhancing employee well-being and improving patient care.

This study aims to examine how digitalization affects the work efficiency of the Shariah Supervisory Board (SSB) in Islamic banks.

Abstract

Purpose

This study aims to examine how digitalization affects the work efficiency of the Shariah Supervisory Board (SSB) in Islamic banks.

Design/methodology/approach

This study uses panel data analysis of annual report disclosures over the past 10 years. The authors have selected 79 Islamic banks for the period ranging from 2012 to 2021. The criteria for SSB efficiency used in this research are disclosure of Zakat and disclosure in the SSB report.

Findings

The econometric results show that digitalization has a positive effect on improving the work efficiency of the SSB in Islamic banks. Accordingly, the authors provide evidence that the higher the bank's digital engagement, the higher the quality of the SSB.

Originality/value

The findings highlight the need to improve the current understanding of SSB structures and governance mechanisms that can better assist Islamic banks in engaging in effective compliance with recent governance and accounting reforms. Moreover, Islamic banks are the most capable and appropriate to implement and activate digitalization because they are based on a vital root calling for development if there are executives believing in it, as well as legislation supporting and serving them.

Abstract

Purpose

This study examined how economic freedom and its related components, such as open markets, regulatory efficiency, rule of law and the size of government, affect bank risk behavior, focusing on the Japanese context.

Design/methodology/approach

The study employs a two-step GMM framework on the annual data of Japanese banks ranging from 2005 to 2020 to empirically test the hypotheses. Furthermore, we also use the ordinary least square method to ensure the robustness of our mainline findings.

Findings

The finding suggests that economic freedom increases the banks' risk-taking, thus making them fragile. The results also highlight that out of the four main subcomponents of economic freedom, regulatory efficiency and government size increase bank risk-taking, while the rule of law and open markets decrease banks' risk-taking. Additionally, we examine how the banks' specific characteristics affect the results by creating a subsample based on capitalization and liquidity ratios. Overall, the results are consistent with the baseline findings. Moreover, the results are robust to alternative proxy measures of risk.

Practical implications

The study's findings have several implications for regulators and policymakers. The results suggest that regulators and policymakers should reconsider their strategies for economic freedom to ensure that they promote stability in the banking system and reduce banks' risk-taking inclinations.

Originality/value

Although previous studies have examined the impact of economic freedom on bank stability and risk-taking, this study is the first to do so in the Japanese context, contributing to the literature by providing new insights and empirical evidence.

Abstract

Purpose

The paper aims to examine the association of green human resource management (GHRM) with organisational sustainability (OS) through the mediating function of corporate social responsibility (CSR) and organisational citizenship behaviour for the environment (OCBE) in Palestinian health-care organisations.

Design/methodology/approach

The paper applied a quantitative method in which data are collected from a survey with 88 human resources and quality managers who work in Palestinian health-care organisations. Furthermore, the structural equation modelling method of partial least squares was used for the data analysis.

Findings

The results demonstrated that GHRM practices positively influenced CSR and OCBE, which eventually influenced OS. Notably, this study offers empirical insights into how to improve OS through CSR, OCBE and GHRM approaches.

Originality/value

This paper presents the implications for achieving the health care sector’s long-term sustainability by linking strategic environmental goals of human resources management practices with practices of social responsibility and organisational citizenship behaviour, which ensures employee participation in formulating policies and strategies for the organization.

Abstract

Purpose

The study aims to inspect the impact of employees’ perception of corporate social responsibility (CSR) and their spiritual values on their affective commitment and job satisfaction, which in turn may promote organizational citizenship behavior. Furthermore, this study examines the moderating effect of Islamic work ethics to identify whether they strengthen or weaken the proposed associations.

Design/methodology/approach

A survey instrument was devised to collect data from employees. The statistical analysis of the data was conducted using the Smart PLS software. Additionally, the research uses the “Partial Least Square-Structural Equation Modelling (PLS-SEM)” technique.

Findings

The findings of the study suggest that employees’ perception of CSR exhibits a positive association with affective commitment and job satisfaction. Likewise, employees’ spiritual values demonstrate a positive and significant correlation with affective commitment and job satisfaction. Finally, the outcomes reveal that affective commitment and job satisfaction play a major role in fostering organizational citizenship behavior. Moreover, Islamic work ethics positively and significantly moderate the relationship between employee CSR perception and affective commitment and between employee CSR perception and job satisfaction.

Originality/value

This research study endeavors to fill the gaps in the current literature by investigating two crucial aspects of employees: their perception of CSR and spiritual values. Additionally, the study includes Islamic work ethics as a moderator to provide a more comprehensive understanding of how these factors contribute to fostering organizational citizenship behavior. This work highlights the significance of spiritual values and social responsibilities in employees’ lives and how Islamic work ethics shape their behavior accordingly.
