This study aims to examine the mediating effect of psychological safety on the relationship between socially responsible leadership and job satisfaction.

A cross-sectional design was used to obtain quantitative data from staff of 214 public universities in Uganda. The authors used Mplus to conduct structural equation modeling (SEM) for this study. Questionnaires were used to collect data.

Socially responsible leadership and psychological safety have a significant positive direct effect on job satisfaction. Further psychological safety significantly mediates the relationship between socially responsible leadership and job satisfaction.

Psychological safety and socially responsible leadership have been found to be important factors in determining how satisfied employees are at work. Furthermore, psychological safety is essential for creating a supportive workplace culture where staff members may freely voice their opinions without worrying about unfavorable consequences. Having a sense of security at work may boost job happiness. It is crucial to remember that there may be a complex link between these elements and job happiness, one that is influenced by a number of other variables including organizational culture, personal traits of employees and the unique circumstances of the Ugandan workplace.

This study contributes theoretically to the examination on the relationship between socially responsible leadership and job satisfaction. This study examined the role of psychological safety as a mediator in the relationship between socially responsible leadership and job satisfaction. Moreover, it has significant effects on the development of literature about socially responsible leadership, psychological safety and job satisfaction in Ugandan public universities.

This paper aims to enhance the stability and control of twin rotor multi-input multi-output system (TRMS) helicopters by introducing a novel approach that utilizes a multi-objective genetic algorithm (MOGA) for optimizing proportional, integral, derivative (PID) controllers in simultaneous pitch and yaw motions.

The TRMS, a common prototype for helicopter motion studies, is introduced, and a PID controller is designed for pitch and yaw stabilization. The gains of the PID controller are optimized using a MOGA, a technique not previously proposed for TRMS in the literature.

While various controllers have been explored in literature for TRMS stabilization, a MOGA-optimized PID controller for TRMS has not been proposed before. Simultaneous optimization of both pitch and yaw motions using two PID controllers is expected to yield improved robustness.

The study focuses on simulations, and experimental validation is not conducted. The MOGA is introduced as an optimization technique, and future studies may explore its application in experimental settings.

This study introduces a novel approach by utilizing a MOGA to optimize PID controller gains for TRMS. Simultaneous optimization of pitch and yaw motions aims to enhance robustness, providing a unique contribution to the field of helicopter control.

Halal brands are crucial in driving the growing global Islamic economy. Despite the importance of brand research and the rich brand literature, there has yet to be a comprehensive study of brand image across halal industries. This study aims to systematically review the existing literature on brand image in halal industries to provide a state-of-the-art understanding and identify opportunities in this research area.

Guided by the Scientific Procedures and Rationales for Systematic Literature Reviews protocol and the theories, contexts, characteristics and methods framework, this paper reviews 35 journal articles from the Scopus and Web of Science (WoS) databases that feature brand image as an underpinning theory in the context of halal economies.

Since the first study almost a decade ago in 2014, brand image research in halal industries has concentrated on consumers in the Islamic finance sector. Keyword co-occurrence analysis reveals that central research themes in halal brand image include outcomes of trust, satisfaction and loyalty. Most studies are focused on halal industries in Muslim countries. The cognitive operationalization of brand image remains dominant in halal industry studies. There is a lack of studies on the moderators of halal brand image. Several unique antecedents of halal brand image are uncovered in this review that are undetected in traditional brand image studies.

The studies in this review are based on the Scopus and WoS databases, which may be perceived as a study limitation. This paper also only considered English journal articles and studies that focused on brand image in halal industries rather than general industries with Muslim consumers.

To become a global brand, halal brands must effectively build and communicate their brand image. This review provides managers with an appreciation of brand image across different halal industries and a strategic lens on universal drivers and those that are faith/ethics related. The consequences of an effective halal brand image can inform and motivate managerial decisions with multiple stakeholders in brand-building campaigns. Researchers can use the results of this review to guide future multidisciplinary studies and contribute toward the development of this research field.

To the best of the author’s knowledge, this paper is the first to comprehensively map the antecedents, dimensions, outcomes and moderators of brand image across halal industries. This study gives managers a strategic understanding of brand image across the halal economy. This review also develops a conceptual model that maps the halal brand image nomological network revealing three key antecedent categories of halal brand image. A research agenda on halal brand image with 18 future research recommendations is introduced to the literature.

Inadequate empirical evidence on the effect of personality traits, entrepreneurship education and university entrepreneurial support on green entrepreneurial intention outcomes among technical university students in Africa has hindered concrete policy interventions. Based on the planned behaviour and social cognitive theories, we assess the influence of personality traits and entrepreneurship education on green entrepreneurial intention of undergraduates at technical universities in Ghana.

We employed an explanatory cross-sectional survey comprising 1,329 Ghanaian undergraduate students to assess the research gap. An adapted 60-item instrument was used to measure outcomes for ten constructs (six personality traits, entrepreneurship education and green entrepreneurial intention) for the participants. A multiple linear regression analysis was used to model green entrepreneurial intention as a function of personality traits, entrepreneurship education and university entrepreneurial support while controlling for respondents’ background characteristics.

We observed a significant direct positive effect of all the personality traits, except subjective social norms and need for achievement, on green entrepreneurial intention. There was also a significant direct positive effect of entrepreneurship curriculum, teaching methods and university entrepreneurial support on green entrepreneurial intention. Our findings further provide empirical data to inform educators, researchers, policymakers and practitioners on the design of pragmatic curriculum, policies and interventions to inspire students into green start-ups.

This study is valuable for its novel approach of using an integrated theoretical and conceptual model to provide empirical validation for the burgeoning discourse around the impact of personality traits and entrepreneurship education on the green entrepreneurial intentions of technical university students in a developing nation. By synthesising diverse theoretical perspectives, this research enriches the understanding of how individual characteristics and educational experiences influence environmentally conscious entrepreneurial aspirations.

This study aims to examine the impact of board gender diversity on sustainable growth by considering the mediating role of investment efficiency (INVEFF) in this relationship and the threshold effect between board gender diversity and INVEFF. This investigation focuses on the Gulf Cooperation Council (GCC) region, which is characterized by rapid socio-economic transformations and a recent emphasis on gender diversity.

Panel data regressions are applied to estimate the impact of board gender diversity on INVEFF using companies listed in the GCC in 2013–2022 as a sample. The estimations consider subsamples of underinvestment and overinvestment, as well as the pre- and post-COVID-19 pandemic periods.

The empirical results show a nonlinear impact of board gender diversity on INVEFF, a relationship that is more pronounced in the underinvestment subsample. The results indicate that INVEFF mediates the relationship between board gender diversity and corporate sustainable growth, which helps companies optimize their board composition to enhance their sustainable growth strategies.

These findings could inform GCC regulators in mandating further increases in women’s presence on boards of directors to improve INVEFF. This study examined only GCC-listed companies. Future research should investigate other factors influencing INVEFF and conduct comparative studies across Middle Eastern and North African countries to consider different regulatory and economic contexts and to examine compliance with international standards.

This study reveals the significant nonlinear impact of board gender diversity on INVEFF and the mediation of INVEFF in the relationship between board gender diversity and sustainable growth. These findings will help companies optimize their board of directors’ composition by increasing the presence of women on boards to improve their INVEFF and sustainable growth. This study aims to develop knowledge that will not only benefit companies regarding the potential impact of board gender diversity but also help international communities create better gender equality within companies.

To the best of the author’s knowledge, this study is the first to explore the relationship between board gender diversity and INVEFF in the emerging economies of the GCC region. It is also the first to examine the nonlinear relationship between board gender diversity and INVEFF and the mediating role of INVEFF in the relationship between board diversity and sustainable growth. This study contributes to the understanding of the financial impact of board gender diversity in improving corporate INVEFF and sustainable growth.

This study aims to focus on sustainable supplier selection in a construction company considering a new multi-criteria decision-making (MCDM) method based on dominance-based rough set analysis. The inclusion of sustainability concept in industrial supply chains has started gaining momentum due to increased environmental protection awareness and social obligations. The selection of sustainable suppliers marks the first step toward accomplishing this objective. The problem of selecting the right suppliers fulfilling the sustainable requirements is a major MCDM problem since various conflicting factors are underplay in the selection process. The decision-makers are often confronted with inconsistent situations forcing them to make imprecise and vague decisions.

This paper presents a new method based on dominance-based rough sets for the selection of right suppliers based on sustainable performance criteria relying on the triple bottom line approach. The method applied has its distinct advantages by providing more transparency in dealing with the preference information provided by the decision-makers and is thus found to be more intuitive and appealing as a performance measurement tool.

The technique is easy to apply using “jrank” software package and devises results in the form of decision rules and ranking that further assist the decision-makers in making an informed decision that increases credibility in the decision-making process.

The novelty of this study of its kind is that uses the dominance-based rough set approach for a sustainable supplier selection process.

Aficionados of wine festivals, a component of wine tourism experience, engage in vigorous online discussions that influence fellow travelers’ purchase behaviors. This study aims to delve into these overlooked discussions, identifying emotions, topics and assessing their usefulness in TripAdvisor’s Travel Forums for two US wine festivals: Taste of Yountville and Epcot International Food and Wine Festival, located in traditional and nontraditional wine tourism destinations.

The study uses state-of-art sentiment analysis and topic modeling methods to extract emotions and underlying latent topics in travel forum discussions. Drawing from information theory, two regression analyses are performed on 10,677 forum posts to examine how the extracted Ekman’s emotions and key underlying topics influence the helpfulness of wine forum posts for each festival.

While three topics were identified in Epcot and four in Yountville, both festival platforms highlight travelers’ common preferences for “culinary experience” and “planning” attributes but reveal notable differences in their utility. Other shared novel findings include the importance of “anger” and “surprise” emotions on the helpfulness of forum posts.

These findings enhance wine festival managers’ and destination planners’ understanding of online travelers’ preferences and cognitive evaluation of user-generated contents’ usefulness. This marketing intelligence informs strategies for boosting the wine destination’s economic development.

This research offers a novel comparative analysis of social media on wine festival tourism experiences in diverse regions. Unlike hotel reviews, typically posted after consumption, forums offer unique and broader perspectives on discussions before, during, and after experiencing the wine festival.

The study examines the effects of corporate governance and countrywide institutions and risk factors on corporate liquidity.

Using firm-level data, the authors analyze the effect of corporate governance and various economic, regulatory and social institutions on the liquidity of firms operating in the Middle East and North Africa (MENA) region. The authors use fixed-effects, firm-specific and country-level controls, disaggregated analysis, sensitivity and endogeneity analysis to test the robustness of the estimates.

The corporate governance characteristics of firms influence in diverse ways their liquidity decisions. The independence and diversity of the board and institutional ownership are especially strong predictors. The effect also depends on the size of the firm and the degree of economic development and exhibits time sensitivity and nonlinearity. Enforcement institutions and risk factors play a strong role.

The analysis contributes to the literature by using a large sample of countries and firms over a larger period, distinguishing between poorer and richer countries and using sensitivity and endogeneity analysis. The analysis considers explicitly the role of regulatory and enforcement conditions, social structures and religious beliefs.

This paper aims to study how corporate governance and country-related contextual factors affect the relationship between board gender diversity and environmental, social and governance (ESG) disclosure in its components: governance, social and environmental.

Using ordinary least-squares and two-stage least squares (2SLS) regressions, and retrieving ESG disclosure data from Bloomberg’s database, the paper analyses a sample of European nonfinancial listed firms (1,935 firm-year observations) over the period 2014–2022. The study adopts board independence and board cultural diversity as structural and demographic board attributes that characterize the corporate governance environment in which female directors operate; the enforcement of law and gender equality as country-related institutional and cultural factors.

Results suggest that female directors may substitute board independence in improving ESG and governance disclosure, whilst they co-occur with board cultural diversity in increasing ESG, governance and social disclosure. Findings indicate that the enforcement of law increases the positive effect of female directors on environmental disclosure and lowers the impact on governance disclosure. Conversely, a more gender-equal environment enhances female directors’ engagement in improving governance disclosure, reducing their beneficial effect on environmental information.

This study contributes to the literature suggesting that structural and other demographic board contextual aspects, as well as institutional and cultural country-related contextual factors, affect the relationship between board gender diversity and ESG disclosure differently and the effect may vary depending on ESG disclosure.

The purpose of the study is to investigate the relationship between the big five personality traits and personal financial planning (PFP) by focusing on the mediating role of mental accounting among Indian service sector employees.

The present study used a data set comprising 649 valid responses obtained through the structured questionnaire that was specifically disseminated to employees working in the Indian service sector. Further, the study used a quantitative approach, partial least squares structural equation modeling, to examine the hypothesized relationship.

The study’s outcomes reveal that mental accounting completely mediates the relationship between conscientiousness and PFP. In addition, extraversion and neuroticism traits have directly influenced the PFP, but in the presence of mental accounting, these traits have partially influenced the PFP. Furthermore, the results suggest that agreeableness directly affects PFP, whereas openness does not demonstrate any significant influence.

The existing literature within the field of PFP has primarily focused on exploring various variables associated with mental accounting, such as monetary and time costs, mental budgeting process and tax liabilities. However, it has overlooked the potential mediating effect of mental accounting. This study bridges this gap by investigating the impact of mental accounting as a mediator in the relationship between personality traits and PFP. Moreover, recently, the Indian economy has undergone major overhauls especially due to enactment of Goods and Services Tax and the profound impact of COVID-19, leading to changes in financial behavior of individuals. Therefore, this study endeavors to shed light on the emerging dynamics within the PFP domain, particularly within the context of the newly accustomed economic circumstances in India.
