Purpose The purpose of this paper is to understand challenges facing organizations in the twenty-first century and address these challenges through suggesting future leadership development based on relevant leadership theories, which would motivate and guide future research directions in a streamlined manner. Design/methodology/approach The present study adopted the exploratory literature review, using the integrative method, to review the theoretical and empirical literature on leadership development published since the 2000s, primarily focusing on research published in the Journal of Management Development. Findings The findings of the current review confirmed that leadership theories are the base for leadership development theories, particularly if the purpose is to address and overcome the current challenges facing organizations. The authors suggest that leadership theories and leadership development theories do not exist in isolation from one another, nor do they exist in isolation from challenges facing organizations. Research limitations/implications This review does not cover all studies before the 2000s nor other journals in the field of leadership. Originality/value Given that most organizations are suffering from one or more of the following issues: sexual scandals, unethical behaviors, individualism, crises and a low level of performance or productivity, the development of particular leadership skills has become a priority. This study is one of few studies guiding both future leadership development research directions and leadership development initiatives.

PurposeThe purpose of this study is to explore and understand the influence of servant leadership on volunteers' commitment working in the voluntary sector in war zones.Design/methodology/approachWith a qualitative research design, participants were 16 volunteers from a servant-leadership-led charity who took part in three focus groups.FindingsResults of the present study revealed that (1) the effectiveness of servant leadership in the war environment lies in creating hope, and (2) the overlap between personal ethics of servant leaders and flexible policies in addition to a set of attributes such as honesty; social awareness; listening; a sense of responsibility; emotion; altruism; patience; and leading without power represent the primary reasons that influence volunteers' commitment during war times.Research limitations/implicationsResearch data was conducted during the war on Syria, which has negative implications not only on the participants, but also on the way they responded to questions.Practical implicationsThis paper explores and attempts to understand the influence of servant leadership on volunteers' commitment working in the voluntary sector in war zones, which can shed light on the importance of servant leadership behavior in the voluntary sector during postwar and reconstruction periods.Originality/valueThe study offers data and interpretation regarding servant leadership and its positive outcome in war zones, which can be used as a foundation for future studies in war zones.

Purpose The purpose of this study is to understand the impact of gender in the sport business by investigating gender differences in entrepreneurial leadership and cultural values using quantitative methods. Design/methodology/approach In total, 241 surveys were completed by sport business owners in 4 countries in the Middle East. Findings The results revealed that gender differences and similarities are not only widely affected by national cultural values but also the effects of national cultural values vary between countries in the Middle East, despite these countries being similar in terms of habits, traditions, history, language and institutional systems. Additionally, it was found that entrepreneurial leadership is a role, task or responsibility that is related to both men and women in the sport business in the Middle East. Research limitations/implications Theoretical and practical implications of the findings are discussed, together with limitations and suggestions for future research. Originality/value This is the only study in the field of entrepreneurial leadership that examined the concept of entrepreneurial leadership in Middle East sport businesses.
