Abstract

Purpose

The paper aims to clarify the hybrid Mg alloy composites reinforced with multi-walled carbon nanotube (MWCNT) and Cerium (Ce) rare earth element tribological properties were investigated by using pin-on-disk test configuration under dry and lubricated sliding conditions.

Design/methodology/approach

The paper opted for an experimental study with composite samples under lubricated conditions. Their tribological properties were investigated by using pin-on-disk test configuration under dry and lubricated sliding conditions. Wear tests were carried out at 20°C temperature. Wear behavior of Mg alloy composites was evaluated as maximum coefficient of friction and the variation of the maximum frictional forces of the samples.

Findings

The reinforcements such as Ce and MWCNT have a decreasing effect between 100 and 200 rpm speed tests for friction coefficient and friction force of Mg alloy. The microstructure has an important effect on the wear mechanism. There can be both adhesive and abrasive wear mechanism for the same composite at different sliding speeds. It is determined that there is no systematic relationship between reinforcement percent and sliding speed related to wear behavior of AZ 41 matrix composites reinforced with CNT and Ce. The results indicate that different wear mechanisms occur at different sliding speeds. The sliding speed has effect on both an increment and decrement for wear.

Research limitations/implications

Because of the chosen research approach, the research results may lack generalizability. Therefore, researchers are encouraged to test the different reinforced composite samples further.

Practical implications

The paper includes implications for the development of a hybrid composite reinforced with rare earth elements and MWCNT.

Originality/value

This paper fulfils an identified need to study a hybrid composite reinforced with rare earth elements and MWCNT.

Abstract

The issue of training and appointment of school administrators has consumed substantial attention from educational scholars for several decades. The literature has witnessed a growing amount of research effort in investigating and identifying the effective ways of training and appointing school principals. However, there are also political, social and cultural aspects to this endeavour, which potentially influences the practices pertaining to training and appointment of school principals. This chapter represents scholarly efforts to discuss issues on the training and appointment of school administrators in Turkey within its historical and political background. Thus, first, it focuses on the historical journey of the field of educational administration in Turkey. This journey has been categorised under three phases: The Ottoman Era, Early Years of Turkish Republic and the 1950s Onwards. Second, this chapter discusses school principalship in Turkey with a specific focus on political and legal dimensions. Finally, the chapter ends with an overall evaluation of the practices and policies pertaining to school administration curriculum in Turkey.

Abstract

Purpose

The purpose of this paper is to explore the relationship between school administrators' power sources and teachers' organizational trust levels.

Design/methodology/approach

The sample of the study, which employed a survey research method, consisted of 376 primary school teachers in Kutahya, a city in western Turkey. The data gathering instrument of the study incorporated “School Administrators' Organizational Power Sources Scale” and “Organizational Trust Scale”. Descriptive statistics and regression analysis were used to analyze the data.

Findings

According to the research findings, the participant teachers' organizational trust levels were high. When power sources used by school administrators were considered, they positively correlated with the teachers' organizational trust perceptions at a moderate level. However, only referent power was the significant predictor of organizational trust perceptions, while referent power, expert power and reward power were significant predictors of trust in administrator. Although the other power sources were highly preferred, they did not have an influence on employees' organizational trust perceptions. Power sources used by administrators explained approximately two‐fifths of total organizational trust perceptions of the teachers and three‐fifths of trust in administrator perceptions.

Research limitations/implications

The research was limited to state primary school teachers' perceptions.

Practical implications

The research findings could be used to analyze primary school teachers' organizational trust environment. To increase the organizational trust levels of the staff, school administrators can prefer the power of expertise, charisma and awards. In this respect, conducting studies especially to develop the expertise of the administrators can contribute to the development of the trust perceptions of the staff.

Originality/value

Although there are studies on organizational trust, research connected to the relationship between power sources preferred by administrators and organizational trust has not been found. Furthermore, organizational power at schools is one of the disregarded fields of education.

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

For Bangladeshi small and medium enterprises (SMEs), the COVID-19 economic shock is remarkable in both its complexity and intensity. SMEs need systemic inspiration to solve the crisis, aligned with a moral and authentic approach that serves both the leader and the follower’s interests. This study aims to conceptualize the innovation-focused success method of SMEs before and after the pandemic to manage the crisis by establishing spiritual leadership based on Islamic perspectives.

Design/methodology/approach

To discuss the impact of spiritual leadership on innovation-focused SME performance configuration through the lens of a crisis, a comprehensive literature study has been carried out in which over 360 articles are read and reviewed by the authors. It has also established the reliability and validity of literature analysis. Also, a qualitative investigation has been used to support the direction of the study.

Findings

For a subsequent process of scientific deployment and evaluation of its execution, a new applied strategic innovation-focused SME success configuration through spiritual leadership development is made available. The primary value of this paradigm is the potential to calculate and treat the aspects of spiritual leadership obtained from Islamic ideas.

Research limitations/implications

Prior analytical or empirical attempts from multiple viewpoints are subsequently needed to inquire about the proposed conceptualization.

Practical implications

Among the realistic consequences of this analysis is that while a number of leadership paradigms have been embraced by a broad body of leadership studies, the findings indicate that this paper should pay heed to the influential spiritual style of leadership, taking into account Islamic perspectives on the context of crisis. Therefore, Bangladeshi SMEs need to develop and run leadership training programs focused on the Islamic viewpoint of spirituality to encourage the actions of leaders during and after crises.

Social implications

The legal and moral values of the society would ultimately be upgraded from this conceptualization. Moreover, less corruption in corporate activities would improve the economic prosperity of a nation. It would also contribute to the cross-cultural portrayal of the positive picture of Islam.

Originality/value

This holistic conceptualization describes the mediating role of strategic innovation practices based on theoretical foundations, which have seldom been done in previous research, between the Islamic model of spiritual leadership and SME success during and after a crisis.

Abstract

Purpose

Artificial intelligence (AI)-based human capital management (HCM) software solutions represent a potentially effective way to leverage and streamline a bank’s human resources. However, despite the attractiveness of AI-based HCM solutions to improve banks’ effectiveness, to the best of the authors’ knowledge, there are no current studies that identify critical success factors (CSFs) for adopting AI-based HCM in the banking sector. This study aims to fill this gap by investigating CSFs for adopting AI-based HCM software solutions in the banking sector.

Design/methodology/approach

Full consistency method methodology and technology–organization–environment, economic and human framework are used for categorizing and ranking CSFs.

Findings

The study identifies the technological and environmental dimensions as the most and least important dimensions for AI-based HCM adoption in banks. Among specific CSFs, compatible technology facilities, sufficient privacy and security and relative advantages of technology over competing technologies were identified as the most important. Implementation of AI-based HCM solutions requires significant outlays of resources, both human and financial, for banks.

Originality/value

The study provides bank administrators a set of objective parameters and criterion to evaluate the feasibility of adopting a particular AI-based HCM solution in banks.

Abstract

Purpose

The application of theories on group decision support is yet to be explored extensively in supplier selection literature, although the literature in both domains is extremely rich, in isolation. The purpose of this paper is to explore the application of group decision support theories for supplier selection.

Design/methodology/approach

The row geometric mean method (RGMM) of the analytic hierarchy process (AHP) has been used in this study for the prioritization of group preferences under consensus. A case study was conducted to test the theories of consensual group decision making and compare it with other approaches based on AHP.

Findings

The study establishes that the application of decision support theories for group decision making can improve the supplier selection process. Findings further imply that RGMM is more effective than eigen value method, for group decision making under consensus.

Research limitations/implications

Methodologically, the study highlights the greater regularity in outcome of group decision making, vis-à-vis individual decision making, for the same decision-making context. Also, it highlights how RGMM is more effective since it preserves reciprocal properties and diversity in preferences better.

Practical implications

The study establishes that firms can improve supplier selection processes by leveraging on the collective expertise of a group rather than depending on individual decision-making expertise.

Originality/value

This study explores the application of different theories based on AHP for consensual group decision making. It compares different approaches based on AHP and establishes that RGMM is a superior approach for supplier selection.

Abstract

Purpose

This paper aims to propose a research model that explores perceived green organizational support (OS) as a mediator of the effect of green human resource management (GHRM) on job performance (JP) and organizational citizenship behavior toward the organization (OCB-O).

Design/methodology/approach

This paper used data obtained from small- and medium-sized hotels in Palestine. The associations given above were tested using structural equation modeling.

Findings

The findings reveal that GHRM boosts hotel employees’ perceptions of green OS. That is, the effective implementation of GHRM is a sign of perceived green OS. Congruent with the study predictions, employees’ perceptions of green OS activate their JP and OCB-O. Finally, perceived green OS mediates the impact of GHRM on JP and OCB-O.

Practical implications

Management should take advantage of green human resource practices to acquire and retain talented employees whose environmental goals and values fit those of the company. Employees should be involved in problem-solving on environmental sustainability and green management. They should also participate in continuous training programs and enhance their awareness of environmental sustainability and green management.

Originality/value

There is a lack of evidence appertaining to the effects of GHRM and perceived green OS on non-green positive workplace performance outcomes. More importantly, there is a scarcity of evidence about the mechanism linking GHRM to these performance outcomes.

Abstract

Purpose

The aim of this study is to provide a holistic analysis of all possible maritime business logistics processes related to import and export shipments in a fuzzy environment through a case study of a maritime logistics company based on the as-is and to-be models within business process management (BPM).

Design/methodology/approach

The analyses considered the following perspectives: (i) in the stage of the process identification, the definition of the problem was carried out; (ii) in the stage of the process discovery, ocean department was divided into ocean export/import operation departments; ocean export/import operation were divided into freight collect/prepaid operation processes; ocean export/import logistics activity groups were broken down into sub-activities for freight collect/prepaid operation; the logistics activity groups and their sub-activities were defined; each sub-activity as either operation or documentation process group was classified; the durations of sub-activities were evaluated by decision-makers (DMs) as fuzzy sets (FSs); the monthly total jobs activities were estimated by DMs as FSs; the applied to monthly jobs activities of total shipments were estimated by DMs as FSs; the durations of each sub-activities were aggregated; the duration of the logistics activity groups and the sub-activities for per job were calculated; the cumulative workload of logistics activity groups and sub-activities were calculated; the duration of sub-activities for per job as operation or documentation departments were calculated, (iii) in the stage of the process analysis, cumulative ocean export/import workload as operation or documentation for freight collect/prepaid were calculated; duration of activity groups and sub-activities for per job as operation or documentation were calculated; cumulative workload activity groups and sub-activities as operation or documentation were calculated, (iv) in the stage of the process redesign, cumulative workload, process cycle time as operation and documentation group and required labor force were calculated; the process cycle time of the theoretical, the as-is model and the to-be model were calculated: (i) the theoretical minimum process cycle time without resource were calculated by the critical path method (CPM), (ii) the process cycle time of the as-is model perspective with the 1 person resource constraint and (iii) the process cycle time of the to-be model perspective with the 2-person resource constraint were calculated by the resource constrained project scheduling problem (RCPSP) method.

Findings

The methodology for analyzing the ocean department operation process was successfully implemented in a real-life case study. It is observed that the results of the to-be model can be applicable for the company. The BPM-proposed methodology is applicable for the maritime logistics industry in the present study; however, it can be applied to other companies in maritime logistics as well as other industries.

Originality/value

This study contributes to research using BPM methodology in maritime logistics. This is the first study the logistics process analyses were carried out in terms of including all operation processes for a company. All processes were analyzed by using BPM methodology in maritime logistics. This study demonstrated the application of the BPM as-is and to-be models to maritime logistics. The as-is and the to-be models of the BPM methodology were applied in maritime logistics.

Research implications

This methodology applied in this study can enable organizations operating in the time-urgent maritime logistics sector to manage their logistics processes more efficiently, increase customer satisfaction, reduce the risks of customer loss due to poor operational performance and increase profits in the long term. Through the use of these methodologies utilizing FSs, the CPM and the RCPSP methods, this study is expected to make contributions to the BPM literature and provide original insights into the field. Furthermore, this study will undertake a comprehensive analysis of maritime logistics with respect to BPM to deliver noteworthy contributions to the maritime logistics literature and provide original perspectives into the field.
