Leadership is an essential contributor to employee creative self-efficacy, and past research suggests a positive relationship between servant leadership and creative self-efficacy. However, the relationship is complex and contingent upon moderating variables, and this research examines the moderating effect of role clarity by drawing on social exchange theory and social cognitive theory.

Data collected from a survey among 116 emergency room employees is used to test the research model using moderated ordinary least squares regression.

The results confirm a positive relationship between servant leadership and creative self-efficacy and suggest a U-shaped relationship between role clarity and creative self-efficacy. Furthermore, role clarity positively moderates the relationship between servant leadership and creative self-efficacy.

The sample used for this research mainly consisted of highly educated employees within a specific setting. Future research is needed to study if the relationships found in this research can be generalized to other organizational settings.

This research suggests that leaders can support employees' creative self-efficacy through servant leadership, particularly when coupled with high role clarity.

Rapidly changing work environments are characterized by decreased role clarity, so attention is needed to its moderating role on the relationship between servant leadership and creative self-efficacy.

The study sought to investigate how servant leadership affects employees' organisational citizenship and innovative behaviour by emphasising the mediation role of psychological empowerment. Relying on social exchange and self-determination theories, the present research examined the associations between these key elements in organisational dynamics.

Two waves of data were obtained from 325 supervisor-subordinate dyads working for 15 nonprofit organisations.

The results uncovered a significant and positive connection between leaders with a strong servant mindset and employees' organisational citizenship and innovative behaviour. Psychological empowerment was found to serve as a mediator in the anticipated correlations. Cultivating leaders with an enduring servant attitude was found to significantly boost employees' organisational citizenship and innovation, supported by improved psychological empowerment.

This study is distinctive as it fills a gap in research on the relationships between servant leadership, psychological empowerment and work outcomes in the global nonprofit sector, particularly in the Eastern context. This disposition, when given the opportunity, will contribute to strengthening working productivity.

This study examines the relationship between servant leadership and its dimensions on firm performance, with big data playing the role of a mediator.

Survey responses used for analysis in this study have been taken from business managers associated reputed private sector organizations in India. A conceptual model is proposed grounded to the Conservation of Resource Theory (COR). Structural equation modeling has been used to test the proposed model.

Servant leadership significantly relates to firm performance, whereby Big Data is seen to play the role of a mediator. The results also indicate that none of the dimensions of servant leadership independently affect firm performance.

The study adds to extant research by examining the mediating mechanism of Big Data in servant leadership and firm performance. It also suggests that each dimension of servant leadership gets reflected in overall servant leadership. Here it is important to note that Big Data analytics partially mediate the effectiveness of servant leadership.

This research aims to investigate the impact of servant leadership on knowledge management and its subsequent connection to cost-saving innovation. The study further explored these relationships by examining the mediating roles of innovation capabilities and technological volatility.

The research is applied in purpose and employs a descriptive-survey method for data collection. It follows a qualitative-quantitative approach, utilizing expert interviews in the qualitative phase. The sample consists of 35 managers and expert professors with knowledge management experience in universities and high-tech industries, selected through the snowball method. Data collected from Iranian organizations were analyzed using AMOS software.

The results revealed a positive correlation between servant leadership and knowledge management. Knowledge management demonstrated a significant positive relationship with cost-saving innovation. Additionally, technological volatility and innovation capabilities were identified as crucial factors influencing the connection between knowledge management and innovation, particularly in promoting frugality.

While this research provides a comprehensive model, it acknowledges specific limitations that warrant further investigation. The study predominantly focused on Iranian organizations, suggesting an opportunity to broaden its scope to include diverse organizational perspectives from various cultural and geographical contexts. Moreover, a promising avenue for future research involves exploring entrepreneurial orientation as a potential mediating variable. Given its significant impact on organizational dynamics, introducing entrepreneurial orientation could enhance our understanding of its effects on both knowledge management and the promotion of frugal innovation. This expansion may illuminate the intricate interplay between entrepreneurial orientation, knowledge processes and innovative practices, contributing to a more sophisticated discussion on effective organizational strategies.

The purpose of this study is to compare the competition and productivity of the US freight rail transportation industry for the past 41 years (1980 ∼ 2020), which consists of the two periods, before and after the abolishment of the Interstate Commerce Commission (ICC) in 1995.

This study investigates any relationships between the market concentration index values and labor productivity values in the separate two periods, and how the existence of a regulatory body in the freight transportation market impacted the productivity of the freight rail transportation industry by using a Cobb–Douglas production function on annual financial statement data from the US stock exchange market.

This study found that, after the abolishment of the ICC: (1) the rail industry became less competitive, (2) even if the rail industry had an increasing labor productivity trend, there was a strong negative correlation between the market concentration index and labor productivity and (3) the rail industry’s total factor productivity was decreased.

This study is to find empirical evidence of the effect of the ICC abolishment on the competition and productivity levels in the US freight rail transportation industry using a continuous data set of 41-year financial statements, which is unique compared to previous studies.

Although change is a necessary part of organisational life, achieving a successful change is complex. Change readiness is a critical element in successful change implementation, yet studies assessing change readiness as an underlying mechanism in the link between organisational-level factors and successful change implementation are scarce, particularly in the African context. Accordingly, the present study examined the extent to which change readiness mediates the link between learning organisation and successful change implementation in the Ghanaian context.

The study utilized a standardized questionnaire to collect data from 364 participants, working in public and private universities in Ghana. The participants were selected via the convenience sampling strategy to complete the survey on the main variables at a single point in time. The study was purely quantitative, as path analysis – a form of structural equation modelling was employed to test the hypothesized relationships in the study.

The results show that both learning organisation and change readiness facilitated successful change implementation. Finally, it was observed that change readiness served as an important mediating mechanism in the link between learning organisation and successful change implementation.

Change readiness was found to explain the link between learning organisation and successful change implementation. Thus, it is important that managers and leaders of public and private sector educational institutions in Ghana invest resources into preparing and getting employees to accept, be committed to and ready for change.

The present study contributes to the scarce knowledge of the mediating role of change readiness in the link between learning organisation and successful change implementation in the African context.
