This study aims to investigate the impact of the transformational leadership style on the behaviour of restaurant employees. Also, it was aimed to investigate the effect of transformational leadership on trust and the effect of trust on altruistic intention and organizational commitment.

The study integrates insights from transformational leadership to provide a fresh perspective to advance comparative organizational behaviour research. To test the hypotheses, the authors conduct a multiple analysis with observations from Turkey getting staff in culinary department with a quantitative survey.

This study equips different professional entities in the food and beverage industry with useful, contextualized links between transformational leadership. According to results, the perspective of transformational leadership style affects the concepts of trust, altruistic value and organizational commitment positively. Charisma, moral modelling and individualized consideration had a significant effect on trust. Also, trust has a significant effect on altruistic intention and organizational commitment.

The present study incorporated confidence as a mediating variable; however, it is recommended that alternative scales be used in subsequent research endeavours. Future research endeavours may incorporate theoretical frameworks such as theory of planned behaviour or stimulus-organism-response.

Transformational leadership style is a good acquisition for restaurant employees. There is a healthier and safer job sharing in these restaurants. This can be interpreted as a more satisfied customer. A good leader has a great contribution to the future and sustainability of the business.

This research created a new model and examined employees’ views on the company and its management. As a result of the analysis, it was determined that charisma, moral modelling and individualized consideration had a significant effect on trust.

This assists in learning better service quality developing and business practices to augment culinary staff, thereby maximizing their valuable contributions to tourism growth. This research created a new model and examined employees’ views on the company and its management.

Researchers, with the widespread acceptance of Web-based technologies by companies, have recently discovered a new type of social capital through these mass communication tools, but there is still limited knowledge about its formation. Therefore, this study specifically aims to conceptualize and validate brand social capital (BSC) by analyzing the role of the online brand community’s social media capital (OBCSC).

Research data was collected using a questionnaire with 39 closed-ended questions. Participants, among the 220 questionnaires distributed, only returned 140 acceptable questionnaires, indicating a response rate of 64%. The statistical population of the study included managers and employees of e-commerce companies active in social media in the field of B2C who introduce and sell their products and services on various types of social networking websites. This study performed data analysis using structural equation modeling with partial least squares.

The results showed that OBCSC has a positive and significant effect on the integration of brand knowledge, branding co-creation and sense of belonging to the brand community, and in addition, using the mediating role of these three variables, it also has a positive effect on BSC. This study rejects only hypothesis 8 among all the hypotheses formulated, which shows that the sense of belonging to the brand community has no significant effect on branding co-creation.

By conceptualizing a new phenomenon called BSC and how its conversion mechanism is, this research defines a specific and formulated path to better identify the results of the organizational use of social media. In addition, it significantly contributes to increasing managers’ understanding of the importance of online brand community activities in internalizing customer brand knowledge within the company and turning it into wealth.

The purpose of this study is to investigate the views of African higher education scholars about effective leadership and if those views reflect a unique, African meaning of leadership.

The study sought to explore the views of African higher education scholars about leadership in general and if those views reflect a unique, African meaning, that does not necessarily fit the widely accepted western theories. Using a researcher-designed questionnaire, higher education faculty and administrators were asked their understanding and beliefs about leadership. Data from quantitative responses were analyzed using descriptive statistics and t-test. In addition, qualitative answers, from one open ended question, were utilized to possibly triangulate with quantitative responses.

This study found that most research participants believe that the widely used western leadership theories are not fully applicable to Africa's context. However, the list of qualities of effective leadership, these participants suggest to be unique to Africa, included mixed attributes from Western, Non-Western and Culture-Neutral theories.

This study has some limitations. First, the data for this study was collected electronically which might have affected the potential responses from those with limited Internet connection or who have not updated their current email addresses. Second, the participants of the study are higher education professionals whose insight about leadership may not necessarily reflect the views of others from different background.

By examining leadership effectiveness in Africa's context, this study adds to the body of literature on the ongoing discussion on the topic of culture and leadership. It is hoped that the findings of the study provide important insights regarding the debate on “western vs non-western” leadership theories.

The universal understanding of leadership and the application of leadership theories across cultures have been an issue of debate for leadership scholars and practitioners around the globe. Many authors argue that the widely used leadership theories are “too western” in value and character (Bass, 1990; Hofstede, 1993; House and Aditya, 1997). This study adds the perspectives of African scholars to the ongoing debate and expands the understanding about leadership across culture.

This study aims to investigate the role of team problem-solving creativity in new product development (NPD) in the bottom-of-the-pyramid (BoP) in business-to-business firms. This study synthesizes perspectives from NPD, creativity and leadership to examine how work-related factors such as NPD managers’ role ambiguity and individual-related factors such as CEO’s ambidextrous leadership style interact to determine team problem-solving creativity and its effect on new product performance (NPP).

The hypotheses are tested using data from a multi-informant survey of 274 middle-level managers within 137 local BoP manufacturing firms in a sub-Saharan African country.

The results show that an NPD team’s ability to solve problems creatively determines NPP in BoP markets. The findings also show that NPD managers’ role ambiguity has a negative effect on team problem-solving creativity. However, a CEO’s ambidextrous leadership neutralizes the negative impact of role ambiguity on problem-solving creativity.

This study combines three distinct streams of literature, including NPD, creativity and leadership, to explore the antecedents and outcomes of problem-solving creativity. Drawing on creativity and leadership theories, this study reports that the success of creative idea exchanges depends heavily on a supportive environment for NPD team members and minimizing the NPD manager’s role ambiguity.

Green innovation (GI) in megaprojects has become a significant research topic that attracts both megaproject management scholars' and practitioners' attention. Green transformational leadership (GTL) is acknowledged as an important antecedent to GI in the permanent context. However, limited research investigates the mechanism and condition of how GTL effectively affects GI in the temporary (i.e. megaproject) context. This study seeks to examine the mechanism and condition of GTL in improving GI by assessing the mediating role of green knowledge sharing (GKS) and the moderating effect of innovation climate (IC).

Regression analysis was performed on data obtained from 303 experts who have been involved in megaprojects.

GTL has a significant positive impact on two aspects of GI, including green product innovation (GPDI) and green process innovation (GPCI). Besides, GKS mediates the relationship between GTL and the two aspects of GI. Moreover, IC plays a significantly positive moderating role in the relationship between GTL and GKS and the relationship between GKS and the two aspects of GI.

This study adds knowledge to the theory and practice by unveiling the “black box” between GTL and GI in the temporary (i.e. megaproject) context. First, this study extends the continuing discussion on the direct effect of GTL on GI to the temporary (i.e. megaproject) context. Second, this study facilitates the understanding of the mechanism to generate better GI performance considering the mediating role of GKS and the moderating effect of IC in the temporary (i.e. megaproject) context. The results can illuminate megaproject practitioners on generating better GI performance.

This paper presents the results of empirical research on the effects of teaching practice on student teachers’ teaching competence and psycho-emotional development using the “most significant change” narrative investigative technique.

Following a qualitative research approach, the study was conducted during the academic year 2021–2022 in two phases (January and May) with the participation of 73 student teachers of the Department of Theology at the National and Kapodistrian University of Athens (NKUA) during their mentored teaching practice. Student teachers’ narratives were collected and analysed using the most significant change technique (Davies and Dart, 2005). Content analysis was conducted with the contribution of seven independent judges.

The results indicate that the Teaching Practice course with the guidance of mentors has a direct and positive effect on student teachers’ teaching competence. Mentors also seem to have a positive effect on student teachers’ psycho-emotional development. The research also confirms the reliability of the most significant change narrative technique for investigating the effect of related educational interventions.

The study empirically validates the usefulness and potential of the investigative narrative most significant change technique for evaluating the effects of teaching practice on student teachers’ professional development with the guidance of experienced mentor teachers. The results of the study also have implications for the design and evaluation of teacher practice programmes.

The purpose of this study is to explore the influence of transformational leadership (TL) on firm's frugal innovation. It also deepens understanding of appropriate mechanisms and conditions to improve specific aspects of frugal innovation namely frugal functionality, frugal cost and frugal ecosystem by examining the mediating role of knowledge management capability (KMC) and moderating mechanism of collaborative culture.

The paper utilized structural equation modeling and cross-sectional design to test hypotheses in the proposed research model using data collected from 351 participants in 112 Vietnamese firms.

The findings indicate that KMC significantly mediates TL's effects on aspects of firm's frugal innovation namely frugal functionality, frugal cost and frugal ecosystem. In addition, the influence of KMC on frugal functionality is different and depended on the extent of collaborative culture in an organization.

The paper has significantly contributed to increasing the understanding of the link between TL and specific aspects of frugal innovation by highlighting the important role of KMC and positive effects of collaborative climate in an organization.

The paper is unique in the attempts to provide the valuable initiatives and integration view of leadership practices for improving specific dimensions of frugal innovation of firms in developing and emerging market.

This study aims to ascertain the role of servant leadership in affecting the knowledge hiding behavior of employees. This study also unfurled the mediating role of prosocial motivation and moderating role of cynicism.

The data were collected from 324 employees working in the IT sector, a subsector of the service sector of Pakistan in two phases. The data was analyzed through hierarchal regression.

This study found servant leadership to be negatively related to knowledge hiding behavior. This study also confirmed the mediating role of prosocial motivation linking servant leadership to knowledge hiding. Finally, cynicism was found to moderate the relationship between servant leadership and knowledge hiding behavior.

This academic endeavor has confirmed the previously unexplored relationship between servant leadership and knowledge hiding behavior. Additionally, the study has explicated the mediating role of prosocial motivation in the said relationship. This study has also found that the relationship between servant leadership and knowledge hiding is moderated by organizational cynicism.

This study aims to analyse the differences between professional interaction mediated by video conferencing and direct professional interaction. The research identifies diverging interests of office workers for the purpose of addressing work ethical and business ethical issues of professional collaboration, competition, and power in future hybrid work models.

Based on 28 qualitative interviews conducted between November 2020 and June 2021, and through the theoretical lens of phenomenology, the study develops explanatory hypotheses conceptualising four basic intentions of professional interaction and their corresponding preferences for video conferences and working on site.

The four intentions developed on the basis of the interviews are: the need for physical proximity; the challenge of collective creativity; the will to influence; and control of communication. This conceptual framework qualifies a moral ambivalence of professional interaction. The authors identify a connectivity paradox of professional interaction where the personal dimension remains unarticulated for the purpose of maintaining professionality. This tacit human connectivity is intertwined with latent power relations. This plasticity of both connectivity and power in direct interaction can be diminished by transferring the interaction to video conferencing.

The application of phenomenology to a collection of qualitative interviews has enabled the identification of underlying intention structures and the system in which they affect each other. This research identifies conflicts of interests between workers relative to their different self-perceived abilities to persevere in competitive professional interaction. It is therefore able to address consequences of future hybrid work models at an existential and societal level.

This study aims to unravel a potential determinant of employee engagement in family firms. In particular, we focus on the role of the CEO by studying the influence of CEO transformational leadership on employee engagement. Moreover, we look into the potential mediating psychological safety might play in this relationship.

Based on an extensive literature review, we propose that there will be a significant positive relationship between family firm CEOs’ transformational leadership and the level of employee engagement. We argue that psychological safety will serve as an underlying mechanism explaining this positive relationship. We empirically tested our research model using quantitative data collected through a questionnaire, completed by 508 employees from Belgian family firms.

The results confirm the positive relationship between CEOs’ transformational leadership and employee engagement. Moreover, these results show that the degree of psychological safety mediates this relationship.

This study forms a significant contribution to family firm literature. Until now, even though existing studies on employee engagement in general are numerous, we had little to no knowledge of the factors influencing employee engagement taking into account the unique context of family firms. With this study, we take an important step in this matter. In addition, this study also contributes to the general literature on employee engagement, since previous studies on the impact of leadership on employee engagement tended to focus on the role of the immediate supervisors and not the CEO.
