Abstract

Purpose

Tribological research is complex and multidisciplinary, with many parameters to consider. As traditional experimentation is time-consuming and expensive due to the complexity of tribological systems, researchers tend to use quantitative and qualitative analysis to monitor critical parameters and material characterization to explain observed dependencies. In this regard, numerical modeling and simulation offers a cost-effective alternative to physical experimentation but must be validated with limited testing. This paper aims to highlight advances in numerical modeling as they relate to the field of tribology.

Design/methodology/approach

This study performed an in-depth literature review for the field of modeling and simulation as it relates to tribology. The authors initially looked at the application of foundational studies (e.g. Stribeck) to understand the gaps in the current knowledge set. The authors then evaluated a number of modern developments related to contact mechanics, surface roughness, tribofilm formation and fluid-film layers. In particular, it looked at key fields driving tribology models including nanoparticle research and prosthetics. The study then sought out to understand the future trends in this research field.

Findings

The field of tribology, numerical modeling has shown to be a powerful tool, which is both time- and cost-effective when compared to standard bench testing. The characterization of tribological systems of interest fundamentally stems from the lubrication regimes designated in the Stribeck curve. The prediction of tribofilm formation, film thickness variation, fluid properties, asperity contact and surface deformation as well as the continuously changing interactions between such parameters is an essential challenge for proper modeling.

Originality/value

This paper highlights the major numerical modeling achievements in various disciplines and discusses their efficacy, assumptions and limitations in tribology research.

Abstract

Purpose

The promulgation of group purchasing organizations (GPOs) into the healthcare (HC) sector is an invaluable procurement strategy to manage the suppliers effectively. This study aims to identify and prioritize the factors of integrating GPOs into the HC sector on the perspectives of the developing countries such as India.

Design/methodology/approach

The factors are identified from current literature exploration, experts’ support and experience surveys. The factors are scrutinized and shortlisted using the Delphi technique and analysed further using the best-worst model method.

Findings

The findings of the study highlight the cost reduction, fair distribution of savings and healthcare supply chain (HCSC) data standardization among others to be the most prioritized drivers. The consulting services provided by GPOs including training and development as a result of high competitiveness in the HC market has been prioritized the least.

Practical implications

The study bears some important implications for decision and policymakers. The managers should consider factors, namely, cost reduction, fair distribution of savings and HCSC data standardization on a priority basis that acts as motivation for the HC providers to join the GPOs.

Originality/value

The study provides valuable insights for HC providers to participate in the GPOs for cost savings and enhance the performances.

Abstract

Purpose

This article investigated whether the executives' compensation and corporate governance attributes are aligned with stakeholders' demands for higher corporate voluntary disclosures. Moreover, the study also examined the moderating role of the auditor's reputation in the direction of association among executive compensation, corporate governance attributes, and voluntary disclosures.

Design/methodology/approach

The study used a sample of S&P BSE index constituents' 90 Indian firms for 2017–2019. The voluntary disclosure scores were fetched from the India Disclosure Index Report published by FTI Consulting. This analysis was carried out in two parts by applying four panel-data regression models in the agency and signalling theories framework. First, the study examined the association between executive compensation, board strength, composition, gender diversity, and voluntary disclosures. Second, the article investigated the moderating role of the “Big 4” in the direction of association among executive compensation, corporate governance attributes, and voluntary disclosures.

Findings

The willingness of executives to share private information with stakeholders depends on the compensation they receive from their employer. The higher compensation paid to executives leads to a higher “tone from the top,” which is better aligned with stakeholder interests. Further, the research also found that bigger board sizes, a higher proportion of independent and woman directors (indicators of good governance), and an auditor's reputation are associated with increased voluntary disclosure.

Research limitations/implications

The findings showed that the executives' compensation and corporate governance attributes are aligned with stakeholders' demand for higher voluntary information from firms. Moreover, the study also found that the “Big 4” play a moderating role in this direction. The choice of a reputed auditor indicates the firms' long-term positive future perspectives, which strengthens investor confidence in the financial market.

Practical implications

The study suggests that fair executive compensation can address the agency problem.

Originality/value

This research furnishes managers and different stakeholders with significant implications of executives' compensation, corporate governance, and auditor's reputation in the best interests of a firm through reducing potential risks of information asymmetry.

Abstract

Purpose

The main purpose of the study is to investigate the impact of gender diversity both at the board and workforce level on firm performance (FP) in the Indian context.

Design/methodology/approach

This study is based on annual data of 200 companies listed on Bombay Stock Exchange (BSE) for the period 2012–2019. The authors have used the fixed-effects (FE) regression and system generalized method of moments to estimate the impact of board gender diversity and workforce gender diversity (WGD) on FP. The authors have used Blau's Index (BI) and Shannon's Index (SI) to measure gender diversity. Further, the authors have used return on assets and Tobin's Q (TBQ) to measure FP.

Findings

The authors' panel regression results suggest that board gender diversity and WGD have a positive and statistically significant impact on FP. The authors' findings are robust across different methods of estimation and alternative measures of FP.

Originality/value

This paper examines the impact of gender diversity both at the board and workforce level on FP of 200 companies listed on BSE. The authors' study contributes to the literature that is sparse in the Indian context and provides new insights on the impact of board and WGD on FP. The findings have useful policy implications. To achieve better performance, it is imperative to appreciate gender diversity at the governance and workforce level in a fast-growing economy like India.

Abstract

Purpose

The aim of this study is to measure the risk disclosure level and to determine the relationship between ownership structure dimensions (institutional ownership, foreign ownership and family ownership) and corporate risk disclosure in Jordan.

Design/methodology/approach

This study used a sample of 94 Jordanian listed firms from the Amman Stock Exchange for the period from 2014 to 2017. This study measured risk disclosure using the number of risk-related sentences in the annual report, while random effects regression was used for hypotheses testing.

Findings

The results revealed that family ownership has a negative effect on risk disclosure practices, but institutional ownership, foreign ownership, firm size and leverage have no significant effect on the risk disclosure level.

Practical implications

The finding of this study is more likely be useful for many concerned parties, researchers, authorities, investors and financial analysts alike in understanding the current practices of the risk disclosure in Jordan, thus helping them in reconsidering and reviewing the accounting standards and improving the credibility and transparency of the financial reports in the Jordanian capital market.

Originality/value

This study offers novel evidence detailing the impact of ownership structure toward corporate risk disclosure, its implementation in emerging markets following the minimal amount of scholarly efforts on the topic. To the best of the authors’ knowledge, this is the first examination of the impact of ownership structure on corporate risk disclosure. Thus, this study has important implications for the decisions of executives, policymakers, shareholders and lenders, as it enables them to better understand the linkage between ownership structure on corporate risk disclosure.

Abstract

Purpose

Studies have so far focused on learning in organizations, factors affecting learning, learning effectiveness and so on but the concept of learning in a hybrid work arrangement is yet unexplored. The purpose of this study is to measure the perception of faculty members in higher education institutions towards learning in a hybrid work arrangement and also to measure the differences of perception towards hybrid work arrangement based on employees’ gender and organization type.

Design/methodology/approach

The data was collected from a sample of 390 faculty members composing of Assistant Professors, Associate Professors and Professors, purposely chosen from two of the premier higher education institutions (one private and one public) located in Punjab, India. A self-structured questionnaire was administered to the faculty members who are working on a regular basis and have minimum of two years of work experience with the chosen university. For analysing the collected data exploratory factor analysis and other descriptive statistics have been applied.

Findings

The findings of the survey show that in terms of gender differences, it is the female employees who are more satisfied with different aspects of hybrid/remote work arrangement as compared to male employees. In regard to organizational differences in the perception towards learning in a hybrid work arrangement it is found that public university employees have a more positive attitude so far as individual factors are concerned, but in terms of organizational factors, it is the private university that is scoring better than the public university.

Research limitations/implications

The study is limited to only two higher education institutions, and its findings to be applicable in all higher education institutions, further studies may be required on a larger canvas. Future studies may be undertaken using advanced statistical tools like structural equation modelling to explore various variables associated with learning in a hybrid work arrangement.

Originality/value

Applicability of hybrid work arrangement is very high in higher education institutions and to the best of the authors’ knowledge, this is the first study which adds to the literature on perception of employees towards organizational learning in a hybrid work arrangement.

Abstract

Purpose

This paper aims to explore the optimization process involved in the aircraft maintenance allocation and packing problem. The aircraft industry misses a part of the optimization potential while developing maintenance plans. This research provides the modeling foundation for the missing part considering the failure behavior of components, costs involved with all maintenance tasks and opportunity costs.

Design/methodology/approach

The study models the cost-effectiveness of support against the availability to come up with an optimization problem. The mathematical problem was solved with an exact algorithm. Experiments were performed with real field and synthetically generated data, to validate the correctness of the model and its potential to provide more accurate and better engineered maintenance plans.

Findings

The solution procedure provided excellent results by enhancing the overall arrangement of the tasks, resulting in higher availability rates and a substantial decrease in total maintenance costs. In terms of situational awareness, it provides the user with the flexibility to better manage resource constraints while still achieving optimal results.

Originality/value

This is an innovative research providing a state-of-the-art mathematical model and an algorithm for efficiently solving a task allocation and packing problem by incorporating components’ due flight time, failure probability, task relationships, smart allocation of common preparation tasks, operational profile and resource limitations.

Abstract

Purpose

The developing field of entrepreneurial marketing reflects input from both marketing and entrepreneurship. Since the early 1980s, it has evolved heterogeneously, without a coherent theory, leading to complex scholarly views. Therefore, this literature review aims to shed light on the recent developments, reveal various research perspectives related to entrepreneurial marketing and derive future research avenues.

Design/methodology/approach

To account for recent scientific contributions and establish a more transparent view of divergent insights, the systematic literature review reported herein covers 207 peer-reviewed journal articles published after the “Charleston Summit” over 12 years (2010–2021) and details their contributions based on descriptive and inductive thematic analysis.

Findings

First, a descriptive analysis illustrates recent scientific developments indicating that entrepreneurial marketing is a vibrant research field with a continuous increase in publications worldwide and a wide range of research methods applied. Second, the thematic analysis suggests a three-part classification into entrepreneur, business and market perspectives. The authors present the most frequent themes and subthemes within this literature domain, as well as offering a critical assessment of the field that reveals key directions for expanding existing research.

Originality/value

To the best of the authors’ knowledge, this study is the first comprehensive review systematically examining entrepreneurial marketing literature while conducting an in-depth thematic analysis. It enhances current knowledge of the field by extending previous narrative and bibliographic reviews and discussing research directions. Aside from specific research questions, an alternative way to narrow down the multiple research objects is elaborated by critically debating the perspectives.

Abstract

Purpose

The purpose of this study is to determine the interactions between factors such as organizational learning, feedback about errors, punitive response to errors and communication quality in hospitals in the Kingdom of Saudi Arabia and Colombia when adopting a culture of quality and safety (CQS) in patient care.

Design/methodology/approach

Based on a literature review, a self-administered questionnaire was developed and used to collect data from 417 Saudi respondents affiliated with hospitals and 483 Colombian respondents at the beginning of the pandemic. Structural equation modeling is used in this study to test the hypothesized relationships.

Findings

The results show a solid and significant predictive relationship between feedback about errors and the CQS in both countries (Colombia: b = 0.55, p < 0.001; KSA: b = 0.44, p < 0.001), but a very low and insignificant predictive relationship between no punitive response to errors and CQS (Colombia: b = –0.02, p > 0.05; KSA: b = 0.05, p > 0.05).

Practical implications

This study demonstrates the importance of organizational learning in fostering a CQS in the health-care sector in the Kingdom of Saudi Arabia and Colombia. Recent unprecedented policy actions motivated by the COVID-19 pandemic, such as social distancing, lockdowns and safety practices enforcement, have further highlighted this concern. Moreover, attention to the dimensions addressed in this study is required for accreditation purposes in organizations seeking to promote a CQS. Overall, this research highlights the vital role of safety and quality practices among health-care organizations, which has significant policy implications, especially in the current period of high uncertainty.

Originality/value

This paper contributes to the theory and practice in the health-care sector by extending the current knowledge of the impact of the quality of communications, non-punitive response to errors and feedback about errors in organizational learning and safety culture, and by presenting a novel, quantitative methodology seldom used for these topics.

Abstract

Purpose

A growing body of evidence points to the influence of location and allocation decisions on the structure of healthcare networks. The authors introduced a three-level hierarchical facility location model to minimize travel time in the healthcare system under uncertainty.

Design/methodology/approach

Most healthcare networks are hierarchical and, as a result, the linkage between their levels makes it difficult to specify the location of the facilities. In this article, the authors present a hybrid approach according to data envelopment analysis and robust programming to design a healthcare network. In the first phase, the efficiency of each potential location is calculated based on the non-radial range-adjusted measure considering desirable and undesirable outputs based on a number of criteria such as the target area's population, proximity to earthquake faults, quality of urban life, urban decrepitude, etc. The locations deemed suitable are then used as candidate locations in the mathematical model. In the second phase, based on the proposed robust optimization model, called light robustness, the location and allocation decisions are adopted.

Findings

The developed model is evaluated using an actual-world case study in District 1 of Tehran, Iran and relevant results and different sensitivity analyses were presented as well. When the percentage of referral parameters changes, the value of the robust model's objective function increases.

Originality/value

The contributions of this article are listed as follows: Considering desirable and undesirable criteria to selecting candidate locations, providing a robust programming model for building a service network and applying the developed model to an actual-world case study.
