The primary objective of this study is to determine how concentrated ownership affects stock returns by country and scale (by market capitalization), like large, medium, and small-cap firms in selected developed economies of the world.

Using a dataset comprising 12,751 annual observations from 850 listed companies from developed economies from 2004 to 2018, the study employs panel data models and instrumental variable estimation to mitigate endogeneity bias.

The findings reveal a significant and positive correlation between ownership concentration and expected returns on corporate equities in developed economies. Furthermore, the study categorizes firms into distinct size categories and finds nuanced differences in the relationship between ownership concentration and stock returns across large, medium, and small-cap enterprises. The results of the study reveal that ownership concentration (by country) and scale (Large, medium, and small) have a significant and positive impact on the stock returns of firms in developed economies.

the practical implications of this study extend to investors, firms, policymakers, regulators, and other stakeholders involved in the financial markets. By considering these implications, stakeholders can make informed decisions to enhance market efficiency, investor protection, and overall market integrity.

To the authors' understanding, this study is the first to examine the impact of concentrated ownership on excessive stock returns across countries and scales, with an explicit focus on large, medium, and small companies in select developed economies worldwide.

Knowledge is an important resource that becomes obsolete if not shared in time. Therefore, this study aims to examine how employees’ perceived fun at work affects their psychological empowerment to evoke knowledge-sharing behavior. The study further explored the conditional role of inclusive leadership between the same.

Using the time lag approach, the data for the current study was collected from 355 employees working in IT firms. The study used convenience sampling, and structural equation modeling was used for hypotheses testing.

The results showed that perceptions of fun have a favorable impact on employees' knowledge sharing behavior and psychological empowerment mediate this relationship. Furthermore, there was no empirical evidence of the conditional role of inclusive leadership between fun and psychological empowerment. However, the results of the alternative model indicated that inclusive leadership moderates the relationship between psychological empowerment and knowledge sharing.

The findings reveal that management should nurture fun at work as it can lead to psychological empowerment and knowledge sharing. The study also reveals that the role of leadership is important for empowerment and knowledge sharing relationships.

Based on the conservation of resources and self-determination perspectives, this study proposes and empirically investigates the mechanism of psychological empowerment and inclusive leadership which has largely been an unattended area of research in knowledge sharing literature.

This paper aims to assess the combined application of Lean Six Sigma and agile approach for optimizing operational processes of order management in the seed industry.

This study is based on an action research case conducted in a multinational Brazilian Seeds Business enterprise. This paper reports on the application of the Lean Six Sigma define-measure-analyze-improve-control (DMAIC), using the steps of DMAIC cycle as a sprint of agile approach. The methodology involves outlining an operational process through sequential activities, each associated with a cycle time, equivalent number of full-time employee and number of orders. Performance metrics for the order management process include continuous monitoring of these activities, using monitoring systems, management software and manual records to collect data.

The findings reveal significant improvements in critical-to-quality measures related to customer care, planning and logistics. The implementation of the DMAIC methodology and agile approach resulted in tangible enhancements in cycle time, defects per opportunities and overall process efficiency. The results allow the classification of defects, the identification of their causes and, consequently, the presentation of a control plan to mitigate these problems. Furthermore, the study identifies key causes of operational issues and proposes a prioritized action plan.

The limitation of this research is its restriction to a single case. The external validity of the results and generalizability to other organizational contexts may be compromised due to the lack of case diversity. The fact that the research focuses on a single company, even if it is a large multinational company, may limit the applicability of the findings to different sectors, sizes and organizational structures, which may be an opportunity for future research.

The findings suggest that the integrated approach of DMAIC and agile methodology contributes to a culture of continuous improvement and operational efficiency. The systematic collection and analysis of data enhance evidence-based decision-making, providing a robust foundation for strategic and operational choices. Moreover, the successful integration of methodologies presents a comprehensive framework applicable to diverse organizational challenges.

The paper applies action research to understand and address operational challenges, emphasizing practical solutions. The integration of DMAIC and agile enhances the depth of process analysis, enabling the identification, implementation and control of improvements. This study offers a significant contribution both to practitioners, providing practical implications, and to academics, enriching the Lean Six Sigma and agile body of knowledge.

This study aims to explore the key challenges and drawbacks of smart contracts (SCs) and how they impact digital resilience within small and medium enterprises (SMEs). Whilst this type of technology is seen as a step forward in terms of traceability, transparency and immutability to increase digital resilience, we argue that it should be approached with trepidation.

In developing this paper, the authors conduct a systematic literature search using the Scopus database. Through this, we identified 931 relevant articles, of which 30 were used as the focus of this article. Thematic analysis was used as the analytical approach to develop themes and meaning from the data.

In this paper, there is an emphasis on the importance of understanding the potential risks associated with SC implementation, as well as identifying appropriate strategies for mitigating any negative impact. In our findings, we puts forward three key themes, namely legality, security and human error, which we argue are key smart contract challenges that impact SME digital resilience.

In this paper, we propose the notion of “centralised control in decentralised solutions”. This comes from the research highlighting SC weaknesses in digital resilience for SMEs. We argue that there is a need for standards, regulations and legislation to address these issues, advocating, ironically, a centralised approach to decentralised technology.

The insidious proliferation of online misinformation represents a significant societal problem. With a wealth of research dedicated to the topic, it is still unclear what determines fake news sharing. This paper comparatively examines fake and accurate news sharing in a novel experimental setting that manipulates news about terrorism.

The authors follow an extended version of the uses-and-gratification framework for news sharing, complemented by variables commonly employed in fake news rebuttal studies.

Logistic regression and classification trees revealed worry about the topic, media literacy, information-seeking and conservatism as significant predictors of willingness to share news online. No significant association was found for general analytical thinking, journalism skepticism, conspiracy ideation, uses-and-gratification motives or pass-time coping strategies.

The current results broaden and expand the literature examining beliefs in and sharing of misinformation, highlighting the role of media literacy in protecting the public against the spread of fake news.

This is, to the authors’ knowledge, the first study to integrate a breadth of theoretically and empirically driven predictors of fake news sharing within a single experimental framework.

Exploring the current phenomenon of the cash waqf-linked sukuk (CWLS) program issuance that involves Islamic banks in Indonesia, this paper aims to investigate the key barriers and intentional behaviors in realizing wealthy Muslims’ contribution to the program using the intermediary function of Islamic banks. Moreover, this study provides a conceptual framework to set effective marketing strategies to encourage wealthy Muslims to become cash waqf founders and sustain their contribution.

This qualitative study used a literature review and in-depth interviews to generate insights for developing a model of wealthy Muslims’ behavior toward cash waqf programs held by Islamic banks.

The study identified low trust, literacy and transparency as the biggest barriers to cash waqf contributions, but suggests that a greater role for Islamic banks, personal engagement and innovative product offerings can help to overcome these barriers. The study also identified three new behavioral dimensions that are important for understanding wealthy Muslims’ contributions to cash waqf: personal financial planning, accountability and political issues. Based on these findings, the study proposes 10 strategies for all stakeholders to pursue in the short and medium term to promote cash waqf contributions from wealthy Muslims.

This study only involved respondents from three major cities in Indonesia: Jakarta, Bandung and Surabaya because these cities have a large number of wealthy Muslims. Future research can collect more samples from all major cities in Indonesia or other Muslim majority countries, and use other qualitative methodology such as phenomenological, ethnographic, grounded theory, case study or action research. The findings of this study can be the starting point for further research and the proposed conceptual framework requires empirical testing in the future.

The findings of this study can be a basis for policymakers and the Islamic financial industry in formulating marketing, education and socialization strategies for innovative cash waqf programs.

The findings of this study will support the acceleration of cash waqf collection for cash waqf initiatives through Islamic banks. Moreover, with a better understanding of the factors impeding and motivating the most potential Muslim groups to contribute to the innovative cash waqf program, the ultimate goal of higher national socio-economic development becomes more attainable.

To the best of the authors’ knowledge, this study is the first to investigate wealthy Muslims’ behavioral factors for contributing to innovative cash waqf held by Islamic banks, from various stakeholder perspectives. It fills a research gap in the literature on innovative cash waqf and behavior.

Drawing on the conservation of resources (COR) theory, this study aims to examine the effects of servant leadership and despotic leadership on employees’ happiness at work (HAW) through job crafting.

To test the hypothesized relationships, the data were collected from 309 Pakistani employees. Structural equation modeling was used to analyze the data.

The findings showed that servant leadership is an optimal leadership style for creating employees’ HAW. In addition, job crafting was found to mediate the effects of servant leadership on employees’ broad-based positive attitudinal outcome (HAW). Moreover, results showed that despotic leadership negatively influences employees’ HAW through job crafting.

This study is novel as it investigates how newer forms of positive (servant) and negative (despotic) leadership styles influence employees’ multidimensional attitudinal outcome (HAW) via job crafting. By doing so, this research extends the nomological network of servant leadership, despotic leadership, job crafting and HAW.

The purpose of this study is to examine factors influencing consumers’ intention to purchase Halal cosmetics through the lens of theory of consumption values (TCV).

This study employed a quantitative research methodology, collecting data from 185 respondents through an online questionnaire. The participants, selected via purposive sampling, were all current purchasers of cosmetics. The data were analyzed using partial least square structural equation modeling (PLS-SEM) with the assistance of IBM SPSS and SmartPLS software.

This research reveals that emotional value is the most substantial value predictor, followed by epistemic value, conditional value and functional value. Further, the moderation analysis shows that the effect of conditional value is strengthened when the consumer are from a higher social class.

This study reveals that consumption values with context-specific attributes directly impact consumer purchase intentions towards Halal cosmetics, while social class acts as a significant catalyst. This offers a fresh perspective that mitigates the traditional misconceptions about Halal cosmetics among Malaysians, highlighting the complexity and resilience of consumer adoption in this innovative sector.

This research aims to build on the pre-existing corpus of literature through the integration of the technology acceptance model (TAM) and usage habit to more accurately capture the determinants associated with social media addiction among university students. This study seeks to delineate how usage habit and TAM may be used as predictors for addiction potential, as well as provide greater insight into current trends in social media usage across this population demographic.

A cross-sectional research design was employed to investigate the determinants of social media addiction among university students in Malaysia at the onset of their tertiary education. A self-administered survey, adapted from prior studies, was administered to a sample of 217 respondents. The hypotheses on social media addiction were subsequently tested using a partial least squares structural equation modeling (PLS-SEM) approach.

Usage habit was found to be a direct and strong predictor of this type of addiction, as well as all TAM variables considered in the research. Additionally, by integrating TAM with usage habit, the study revealed a comprehensive and multi-faceted understanding of social media addiction, providing an important insight into its complexity in the Malaysian context. Although several other factors have been identified as potential contributors to social media reliance and addictive behavior, it appears that usage habit is paramount in driving these addictive tendencies among university students.

This expanded model holds significant implications for the development of interventions and policies that aim to mitigate the adverse effects of social media addiction on students' educational and psychological well-being. The study illustrates the applicability of the TAM in examining addictive behaviors within emerging contexts such as the Malaysian higher education sector, thus contributing to the extant literature on the subject.

The integrated TAM and habit model is an effective predictor of social media addiction among young adults in developing countries like Malaysia. This highlights the importance of actively monitoring and controlling users' interactions with technology and media platforms, while promoting responsible usage habits. Educators can use these findings to create tailored educational programs to educate students on how to use technology responsibly and reduce their risk of becoming addicted to social media.

This study provides a unique perspective on social media addiction among university students. The combination of TAM and usage habit has the potential to shed significant light on how variables such as perceived usefulness (PU) and perceived ease of use (PEOU) may be associated with addictive behaviors. Additionally, by considering usage habit as an explanatory factor, this research offers a novel approach to understanding how addictions form over time.
