Abstract
Purpose
The study aims to optimize truck routes by minimizing social and economic costs. It introduces a strategy involving diverse drones and their potential for reusing at DNs based on flight range. In HTDRP-DC, trucks can select and transport various drones to LDs to reduce deprivation time. This study estimates the nonlinear deprivation cost function using a linear two-piece-wise function, leading to MILP formulations. A heuristic-based Benders Decomposition approach is implemented to address medium and large instances. Valid inequalities and a heuristic method enhance convergence boundaries, ensuring an efficient solution methodology.
Design/methodology/approach
Research has yet to address critical factors in disaster logistics: minimizing the social and economic costs simultaneously and using drones in relief distribution; deprivation as a social cost measures the human suffering from a shortage of relief supplies. The proposed hybrid truck-drone routing problem minimizing deprivation cost (HTDRP-DC) involves distributing relief supplies to dispersed demand nodes with undamaged (LDs) or damaged (DNs) access roads, utilizing multiple trucks and diverse drones. A Benders Decomposition approach is enhanced by accelerating techniques.
Findings
Incorporating deprivation and economic costs results in selecting optimal routes, effectively reducing the time required to assist affected areas. Additionally, employing various drone types and their reuse in damaged nodes reduces deprivation time and associated deprivation costs. The study employs valid inequalities and the heuristic method to solve the master problem, substantially reducing computational time and iterations compared to GAMS and classical Benders Decomposition Algorithm. The proposed heuristic-based Benders Decomposition approach is applied to a disaster in Tehran, demonstrating efficient solutions for the HTDRP-DC regarding computational time and convergence rate.
Originality/value
Current research introduces an HTDRP-DC problem that addresses minimizing deprivation costs considering the vehicle’s arrival time as the deprivation time, offering a unique solution to optimize route selection in relief distribution. Furthermore, integrating heuristic methods and valid inequalities into the Benders Decomposition approach enhances its effectiveness in solving complex routing challenges in disaster scenarios.

This study aims to investigate whether auditors compromise their independence for economically important clients in family business settings.
Abstract
Purpose
This study aims to investigate whether auditors compromise their independence for economically important clients in family business settings.
Design/methodology/approach
The authors empirically examine the research question based on China for the years 2011 to 2020. The dependent variable is the auditors’ propensity to issue modified audit opinions, which is a proxy for auditor independence. The authors use relative client audit fees as a proxy for client importance. To address endogeneity issues in the selection of family firms, the authors use the two-stage least squares regression model and, subsequently, the propensity score matching and Hausman firm fixed effect modeling.
Findings
This study reveals that the propensity to issue modified audit opinions is positively correlated with client importance. Big-N auditors are more likely to issue modified audit opinions for their economically important family firm clients, whereas such evidence is not found for non-Big-N auditors. Results are consistent and robust to endogeneity test and sensitivity analysis.
Originality/value
This study enriches the literature on auditor independence and the effect of family firms’ ownership structure factors on audit reporting behavior for their economically important clients. Findings may prove useful for managers and practitioners interested in family business.

Abstract
Purpose
Organizational commitment could influence nurses’ turnover intention, but we know little about how effort recognition may enhance all three aspects of nurses’ organizational commitment and consequently reduce their turnover intention. This study adopts the self-affirmation theory to examine how the number of effort recognitions received by a nurse may impact the normative, continuance and affective aspects of their organizational commitment and their turnover intention.
Design/methodology/approach
We collected two-wave data from the survey responses of 481 nurses in a large medical center in Taiwan between June and August, 2017 and between January and February, 2018 as well as counting the number of times their efforts were recognized as excellent by using patient/family performance appraisal forms in 2016. Bivariate correlation was used to test the hypotheses.
Findings
We found that effort recognition is positively associated with nurses’ normative organizational commitment but not with their continuance or affective commitment. The three aspects of organizational commitment are negatively associated with turnover intention.
Practical implications
Nurse managers who hope to reduce nurses’ turnover intention could consider adequately recognizing nurses’ outstanding performance.
Originality/value
The present study is the first to employ the self-affirmation theory to examine the impact of effort recognition on the three aspects of organizational commitment and turnover intention.

Abstract
Purpose
This study aims to examine the effects of agency cost on auditor choice. This paper also deals with the moderating role of the board’s financial expertise (Bfe) and the status of the internal control (Intecon) system on the relationship between agency cost and auditor selection.
Design/methodology/approach
This study’s sample consists of 1,040 firm-year observations of Iranian nonfinancial companies listed on the Tehran Stock Exchange from 2012 to 2019. The information required for this research is mainly extracted from Comprehensive Database of All Listed Companies (in Iran Stock Exchange). Data from 130 companies were obtained during the research period. This study used logistic regression to test the hypotheses.
Findings
The findings indicate that companies with higher agency costs choose the auditor from lower classes. As the proportion of financial expert members on the board increases, the intensity of this relationship will be reduced. Companies with higher agency costs choose the auditor from the lower classes, but the higher the ratio of financial expert board members, the more these companies will choose high-quality auditors. However, findings showed that the status of the Intecon system has no moderating effect on the relationship between agency costs and auditor selection.
Originality/value
The results of this study can expand the existing literature on the relationship between auditor selection and agency costs and the factors affecting this relationship, especially the Bfe and Intecon. This research has significant suggestions for regulators, stakeholders, shareholders and analysts in emerging economies that may encounter similar contextual implications.

Abstract
Purpose
The purpose of this study is to explore the moderating effect of Confucian values and the mediating effect of relationship quality on the relationship between organizational justice and employee service orientation in the tourism and hospitality industry.
Design/methodology/approach
Structural equation modeling was applied to a sample of 421 responses in a questionnaire survey from employees of tourism and hospitality firms in mainland China.
Findings
Employee relationship quality fully mediated the relationship between organizational justice and service orientation. Confucian values negatively moderated the direct effect of organizational justice on employee relationship quality and the indirect effect of organizational justice on service orientation.
Practical implications
This study offers insights for hospitality managers how to improve employee service orientation and establish Confucian values in the practice of organizational justice. Tourism and hospitality organizations should equally treat all employees as internal customers and use distinct strategies to manage employees with high and low Confucian values in employee selection and management of training and development.
Originality/value
This study highlights the contributions of organizational justice and relationship quality to employee service orientation. It also demonstrates that Confucian values explain why many Chinese employees are less sensitive to low fairness: these values negatively moderate the organizational justice–relationship quality–service orientation relations. By linking organizational justice to relationship quality and employee service orientation, the findings enrich our understanding of the applications of internal marketing and social exchange theories under Confucian values.

Abstract
Purpose
There is a growing body of literature discussing the green logistics practices (GLPs) that companies could introduce to reduce the logistics environmental impact. Current approaches also identify several influencing factors within firms that could serve as barriers to, or enablers of, GLPs. However, less is known about the role of extra-firm stakeholders, even though these are crucial to operationalizing green logistics effectively. This study merges current theoretical understanding with empirical evidence to provide a detailed stakeholder analysis of GLPs.
Design/methodology/approach
Using stakeholder theory as a theoretical lens, the authors aimed at offering a mid-range contribution by conducting multiple embedded case studies examining Italian logistics service providers and shippers. GLPs and the related influencing factors were examined as sub-units of analysis within broader companies' environmental sustainability strategies.
Findings
The authors identified cascading effects among factors influencing the adoption of GLPs (e.g. key economic factors are affected by external factors which also influence organizational and collaboration factors). These effects are moderated by interdependencies between primary and secondary stakeholders, and the study highlights the prominent involvement of secondary stakeholders, such as final consumers.
Originality/value
This paper contributes to better understanding how and why companies adopt GLPs, emphasizing the wide set of stakeholders involved and illustrating how different stakeholders impact on GLPs adoption by affecting a set of influencing factors. By combining insights from the available literature with contemporary empirical data, the authors emphasize how Logistics Service Providers (LSPs) and shippers can no longer address the adoption of GLPs as “focal companies”, but only as part of a “focal network of interconnected stakeholders”, all of them influencing GLPs adoption.

Abstract
Purpose
The purpose of this work is to honor the wisdoms of Anishinaabe Elders, community and culture by interweaving these teachings with my own (first author) Anishinaabe experiences and a research project. Ceremonies are an important health practice for Anishinaabe people. This project aimed to gain a clearer conceptualization of the protective role of Anishinaabe puberty ceremonies on health in adolescence and across the lifespan.
Design/methodology/approach
Spiritual offerings guided this project at every stage including inviting Elders and community members into shared spaces of storytelling and teaching elicitation and grounding me as I carefully adopted the use of a western tool (research) in sacred community spaces. Elders were invited to share their experiences and perspectives. Three community members engaged with the interview transcripts on their own before coming together to discuss themes, patterns and insights that arose for them. This group coding discussion constructed the structural foundation of the findings.
Findings
An Anishinaabe perspective on youth development emerged. Key aspects of this model included a foundation of ceremonial experiences that spiritually prepares a child for adulthood and impending life’s challenges. As one transitions into adulthood, they accept the responsibilities of being caretakers of their families and communities and gain new tools to contribute to Anishinaabe society. Ideally, this society prioritizes Anishinaabe spirituality, language and way of life.
Originality/value
Frameworks of health, grounded in unique community wisdoms and worldviews, are imperative to repair spiritual and community relationships damaged in a history of colonialism. An Anishinaabe perspective on youth development may shed light on shared Indigenous experiences of cultural restoration and continuity.

Abstract
Purpose
The Purpose of this paper is to identify statistical relationships between visual environment and occupant productivity. Visual environment is one of the most important indoor environmental quality (IEQ) parameters, and it directly impacts occupant productivity in offices. The literature outlines the significance of the impact. Still, there is a lack of investigation, statistical analysis and inter-relationships between the independent variables (IEQ factors), especially in the hot and arid climate.
Design/methodology/approach
This study presents a research study investigating the effects and shows statistical relationships between IEQ on occupant comfort and productivity. The study was conducted in the Middle East, and data was collected for 12 months. It used the response surface analysis to perform analysis.
Findings
This study outlined seven unique relationships highlighting the recommended range, inter-dependencies. Results include that illumination has maximum effect on visual comfort and temperature, daylight having direct influence and relative humidity, wall type next to the seat and kind of workspace also impact visual comfort and productivity. These findings would help to improve occupant comfort and productivity in office buildings. It is recommended to include results and recommendations on design guidelines for office buildings.
Originality/value
This study presents the unique effects of non-visual IEQ parameters on visual comfort and productivity. This investigation also provides a unique method to develop the statistical relationship between various indoor environmental factors and productivity in different contexts and buildings.

Abstract
Purpose
The aim of this study is to examine the nature and determinants of stock market integration between India and other Asia–Pacific countries (Malaysia, Hong Kong, Singapore, South Korea, Japan, China, Indonesia, the Philippines, Thailand and Taiwan) over the period 1991–2021.
Design/methodology/approach
Unit root tests, the dynamic conditional correlation-Glosten Jagannathan and Runkle-generalized autoregressive conditional heteroscedasticity (DCC-GJR-GARCH), pooled ordinary least squares (OLS) regression and random effects models are employed for the analysis.
Findings
The empirical results show that the DCC between each pair of sample countries is less than 0.5, indicating weak ties between the pairs of sample countries. Also, the DCC between India and other Asia–Pacific stock markets is positive and low, implying low level of integration. The correlation between India and China stock markets is found to be the highest, implying significant level of integration. The main reason for it would be strong economic linkages and bilateral trade relationship between India and China. Moreover, gross domestic product (GDP), interest rate (IR), consumer price index (CPI)-inflation and money supply (MS) differentials are the major driver of stock market integration between India and other Asia–Pacific countries.
Practical implications
The findings of the study have important implications for investors, portfolio managers and policymakers. It is found that the DCC between India and other Asia–Pacific countries (considered in the study) except China is low, which indicates weak ties between the pairs of sample countries. This implies that the Indian stock market provides good investment opportunities for foreign investors. Also, investors and portfolio managers can attain more diversified benefits and can minimize country risk by investing across Asia–Pacific countries. Further, knowledge about the factors that integrate the Indian stock market with the other Asia–Pacific stock markets will help policymakers frame suitable economic and financial stabilization policies.
Originality/value
This study contributes to the extant literature: first, by examining the linkages of Indian stock market with other Asia–Pacific countries; second, although previous studies confirmed the existence of linkages among the various stock markets, few researchers pay attention to the factors driving the process of stock market integration. This study provides additional evidence by examining the significant macroeconomic factors driving the process of such integration in the Asia–Pacific region considered under the study.
