The present study examines the effects of transformational leadership exercised by team leader and transformational leadership shared by team members on team creativity and team performance at the team level. A growing body on leadership research highlights the role of team leadership in work organizations. In team settings, studies have focused exclusively on individual leaders who occupy formal leadership positions and exercise vertical influence over team members. In contrast to this traditional approach, shared leadership highlights a horizontal influence process where leadership is collectively carried out by team members. In this shared form of leadership, members actively participate in the leadership process and horizontally influence other team members. This mutual influence among team members constitutes a critical condition for the success of team-based organizations. The ability of team members to work together as a team is the key to the overall functioning of the team organization. To verify the effect of two leadership styles, we analyze the effect of a leader's transformational leadership and members' shared transformational leadership on team creativity and team performance for the same team. This study also predicts that the transformational leadership shared by members will moderate the effects of leader transformational leadership on team performance and creativity. Our findings show that both leaderships have a positive effect on team performance. However, the main effect of a leader's transformational leadership on team creativity is not significant when members' transformational leadership is employed into the model. With the effect of leader transformational leadership controlled for, the main effects of the transformational leadership shared by members on team creativity and performance are significant. In addition, we also found the significant moderation effects of member transformational leadership by leader transformational leadership on team creativity. Based on these findings, we strongly recommend that team based organizations shift the leadership focus from the leader focused leadership model to the shared leadership model. We also discuss managerial implications of our findings in details.

Purpose - This study investigated the effects of leaders of national universities on faculty creativity. The study examined transformational leadership and creativity theories and investigated self-efficacy, the parameter between transformational leadership and creativity, to examine its moderating effect and provide policy implications for national universities. Research design, data, and methodology - This study built four hypotheses based on the literature review, and tested these using a survey methodology. The collected data were analyzed using SPSS 15.0. Result - At the national universities, the results were as follows: charisma of leaders had a positive influence on member creativity; intellectual stimulus of leaders had a positive influence on member creativity; and, individual consideration of leaders had a positive influence on member creativity. Therefore, leaders' transformational leadership had a positive influence on member creativity. Conclusion - Creativity is thought to be important for organizational survival and continuous development at rapidly changing education administrations. Educational administration leaders should exercise transformational leadership to develop member creativity. Member self-efficacy, which had a mediating effect on creativity, requires leadership to develop it.

Transformational and authentic leadership are known to create positive effects on follower's various outcomes, like job satisfaction and organizational commitment. We're mostly interested in testing positive effects of transformational and authentic leadership of cabin team leaders in airline industry, because their leadership tends to have strong and immediate impact on cabin crew's quality of customer services. We figured that cabin team leader's transformational and authentic leadership had positive effects on crew member's job satisfaction and organizational commitment. And, these positive relationships were at least partially mediated through crew member's self-efficacy and LMX. Based on these positive results, we discussed several theoretical and practical implications for developing effective leadership across cabin team leaders in airline services industry.

The purposes of this study were (1) to describe the effects of transformational leadership and transactional leadership on the hospital member's organizational commitment and turnover intention, (2) to provide with fundamental data in enhancing organizational effectiveness. For this purpose, the types of leadership, organizational commitment and turnover intention were evaluated among hospital members. A survey was conducted with 827 respondents working in a general hospital in Sungnam-shi. For the data analysis SPSS 10.0 was utilized. To verify the reliability and validity of variables, Chronbach's ${\alpha}$ and confirmatory factor analysis were processed. After descriptive analysis, regression analysis was conducted. In these progresses all the statistical significant levels were set at ${\alpha}$= 0.05. Results of the study can be summarized as follows. First, the types of leadership had differences in the level of organizational commitment and turnover intention of the hospital members and then transformational leadership had a more influence than did transactional leadership. Second, there were significant correlations for organizational commitment and turnover intention with overall characteristics of leadership(p<.05). Third, the factor influencing hospital member's organizational commitment and turnover intention were transformational leadership(p<.001). Total explanatory powers($R^2$) were 20.2% (organizational commitment) and 12.1%(turnover intention). Multiple regression analysis demonstrated that organizational commitment significantly high when transformational leadership was higher and it also showed turnover intention was significantly lower. In conclusion, the results of this study show that the leadership influence hospital member's organizational commitment and turnover intention and they are different the types of leadership. This results suggest that in order to be as successful leaders in hospital, the leaders should know their employee's behaviors and change their leadership styles.

In this paper, we propose the role of job crafting in the relationship between leadership and organizational effectiveness in voluntarily carrying out each member's assigned tasks. This study surveyed the manufacturing, construction, service industries in Seoul and Gyeonggi province, identified the type of leadership they recognized, and empirically analyzed the organizational effectiveness of leadership. The purpose of this paper is to grasp the types of leadership acknowledged by the industry of manufacturing, construction, and service, and also to empirically analyze the organizational effectiveness of the leadership. The study measures the organizational effectiveness in terms of the job satisfaction, organizational commitment, and organizational citizenship behavior while classifying the leadership into coaching leadership, transformational leadership, and sensible leadership. In addition, the strictness of the analysis is imposed by estimating the simple least square model and ranking probit model. The results of the least square model is summarized as the following. Regardless of the different defining terms of organizational effectiveness, transformational leadership was shown to have the greatest organizational effectiveness. Sensible leadership positively effected job satisfaction whereas coaching leadership positively effected job satisfaction and organizational effectiveness. Compared to transformational leadership and coaching leadership, the impact of the sensible leadership was very much limited. The result of the ranking probit model is summarized as the following. First, sensible leadership had a positive impact on the member's job satisfaction and organizational commitment. Second, regarding the organizational citizenship behavior, coaching leadership showed greater impact than transformational leadership. This results contradicts the results from the simple least square model. If similar studies were to be conducted in the future, two models and the results must be compared. Third, as the leadership score increases by 1 point, there is greater possibility of having more than 4 points for all job satisfaction, organizational commitment, organizational citizenship behavior. Lastly, the analysis proves that job crafting has the mediation effect between the leadership and organizational effectiveness.

One of the organizational characteristics in the modern society is the emphasis placed upon individual autonomy in an effort to promote and develop each member's morale as well as the efficiency in personnel management. Therefore, it can be understood that the importance of "Self" is recognized in work places and the leadership of supervisors and each member's self-management and control are also emphasized, leading to establishment of the "Self-leadership" concept. In this study, the effect of the Transformational Leadership of the supervisors on the subordinates' Self-leadership was analyzed and the causal factor of organizational support in the relationship between Transformational Leadership and Self-leadership was defined. A survey was conducted with 182 security officials at the National Assembly and the following results were obtained. First, Transformational Leadership had a positive effect on Self-leadership and the Transformational Leadership of the supervisors had a statistically significant impact on the organizational support awareness. Furthermore, organizational support showed a statistically significant mediator effect in the relationship between the Transformational Leadership of the supervisors and the Self-leadership of the subordinates. Finally, future directions in regard to the personnel management system were suggested.

The main purpose of this study was to find antecedents of organizational citizenship behavior(OCB) and to investigate the mediating role of leader-member exchange(LMX). This study categorized the factors that influence OCB and LMX into individual(distributive and procedural justice), group(transformational leadership and team empowerment), and organizational levels(complexity). A total of 773 cases were used in this study, which were collected in one of industrial complexes. The research participants were any employees who participated in their work by collaborating with their co-workers. This study found that procedural justice, transformational leadership, and team empowerment had positive influences on OCB, and distributive justice, procedural justice, transformational leadership, team empowerment, and complexity significantly influenced LMX. Moreover, LMX played a mediating role in the relationship between each of the five input variables and OCB.

This study examines the effects of transformational leadership on helping behavior for the secretary workers. We also demonstrate comprehensively the moderating effects of job resources(LMX) and job demands(utilization of mobile devices after work) on the relationship between transformational leadership and helping behavior. The results of this study targeted 140 incumbent secretaries are as follows: First, transformational leadership has a significant positive effect on the helping behaviors of members. Second, the interaction effect of LMX(synergistic effect) was verified in the positive relationship between transformational leadership and helping behavior. Finally, interaction effects of utilization of mobile devices after work(buffering effect) were confirmed in the relationship between transformational leadership and helping behavior. The results of this study are that transformational leadership of middle managers is important to strengthen worker's helping behavior, but it is also important to understand the contextual factors such as social support(LMX) and work environment(utilization of mobile devices after work) that affect the will and autonomy of members in accepting leadership. Finally, we suggest the theoretical and practical implications of this study, present limitations and future research directions.
