  • According to the social learning theory, leader' organizational citizenship behavior (OCB) is a predisposing factor for follower' OCB, because they acknowledge and imitate leader as a desirable example of behaviors for organizational and individual success. We investigate social learning effect of leader OCB on follower OCB and examine the moderating role of political skill in the mediated relationship between leaders OCB and follower OCB (with followers' affective organizational commitment as the mediator). We find that follower's affective organizational commitment may mediate the relationship between leader OCB and follower OCB. Furthermore, we find that follower with high political skill may focus on the instrumental value of OCB. Political skill moderates the relationship between follower' affective organizational commitment and follower OCB. Data from 325 leader-follower dyads support the hypothesis. Theoretical and practical implications of these findings are also discussed.

  • This paper presents obstacle avoidance of Leader-Follower formation. The follower robot maintain the formation with leader robot and avoid the detected obstacle. When obstacle is detected, follower robot avoid it considering leader robot and follower robot position and follower robot and obstacle position. In addition, follower robot avoid obstacle irrespective of obstacle size. Controller of follower robot is designed to satisfy Lyapunov stability by backstepping method. Simulation results shows that the designed controller has a stable performance.

  • This paper proposes the leader-follower based formation control method for multiple mobile robots. The controller is designed using the measurements of the follower robot such as the relative distance and angle between the leader and the follower. This means that the follower robot does not require the information of the leader robot while keeping the desired formation. Therefore, the proposed control method can reduce the communication loss and the cost for hardware. From Lyapunov stability theory, it is shown that all error signals in the closed-loop system are uniformly ultimately bounded. Finally, simulation results demonstrate the effectiveness of the proposed control system.

  • 본 연구는 리더 또는 구성원의 자기보고에 의한 일방향적인 LMX 지각과 성과와의 관계를 규명한 기존 연구와 달리, LMX지각의 정합성을 바탕으로 리더와 구성원의 LMX 지각의 균형과 불균형에 따른 조직정치지각 및 정서적 조직몰입의 차이를 규명하였다. 특히, 불확실성관리이론에 근거하여 LMX지각의 정합성 차이에 따른 집단별로 구성원의 조직정치지각이 정서적 조직몰입이 미치는 영향을 실증하였다. 연구결과, 먼저 정서적 조직몰입은 균형/LMX 고집단이 균형/LMX 저집단과 구성원 저평가집단에 비해 높았으며, 구성원 고평가집단 역시 균형/LMX 저집단과 구성원 저평가집단에 비해 높았다. 둘째, 조직정치지각은 균형/LMX 고집단이 균형/LMX 저집단과 구성원 저평가집단에 비해 낮았으며, 구성원 고평가집단은 균형/LMX 저집단에 비해 낮았다. 마지막으로 불확실한 정치적 업무환경에서 구성원의 정서적 조직몰입은 모든 집단(균형/LMX 고집단, 균형/LMX 저집단, 구성원 저평가집단, 구성원 고평가집단)에서 감소되었다. 특히, 내집단에 비해, 외집단의 구성원들이 정치적 업무환경 하에서 정서적 조직몰입에 더욱 부정적으로 반응하였다. 마지막으로 종합논의를 통해서 본 연구의 이론적 실무적 시사점과 한계점 및 향후 연구방향을 제시하였다.

  • Nash Equilibrium (NE) is as useful tool for investigating a participant's strategic generation quantity in a competitive electricity market. Cournot model may give a mixed strategy NE instead of a pure strategy when transmission constraints are considered. A mixed strategy is difficult to compute, complicated to understand conceptually, and hard to implement in an electricity market practically. This paper presents that a mixed strategy does not appear in Stackelberg leader-follower model even under a transmission congestion. A solution method is proposed for the leader-follower model under a nondifferentiable space of a strategy variable. Based on the pure strategy NE with a transmission line congested, the merit of leader-follower model is shown from a social welfare point of view.

  • This paper proposes about decentralized control approach based Leader-Follower formation control using LOS (Line of Sight) algorithm and unknown input observer. The position of robots which is a basic information in multi-robot or single robot motion control is determined by localization algorithm fusing UPS (Ultrasonic Position System) and kinematics model. For formation control, a decentralized control approach individually installing a local controller in leader and follower robot is adopted. Leader robot is controlled to track a specified trajectory by LOS algorithm, and the other robots follow the leader by local controller based on tracking platoon level function, self-sensing data and estimated information from unknown input observer. The performance of proposed method is proven through the formation experiment of two vehicle models.

  • Purpose: This paper investigates the effects of leader feedback on employee creative problem-solving behavior. It also explores the relevant conditions that maximize the above relationship from the psychological trait and task nature perspectives. Specifically we examine how employee feedback acceptance and task complexity moderate the relationship between leader's feedback behavior on follower creative problem-solving behavior. Finally the three-way interaction among leader's feedback behavior, employee feedback acceptance and task complexity is analyzed for the best conditions to maximize the positive effect of leader's feedback on creative problem solving behavior. Methods: This paper used a cross-sectional design with questionnaires administered to 411 employees working in Korean manufacturing and service firms. It applied a hierarchical regression analysis to test the hypothesized relationships including three-way interaction effect among leader's feedback behavior, follower feedback acceptance and task complexity on follower creative problem-solving behavior. Results: The empirical results of the paper indicated that the leader feedback behavior had enhanced employee creative problem-solving behavior. It was also found that follower feedback acceptance and task complexity positively moderated the relationship between leader's feedback and follower problem solving behavior. In addition, the test of three-way interaction effects also revealed that the higher the levels of both employee feedback acceptance and task complexity, the greater the positive effect of leader feedback behavior on employee creative problem solving behavior. Conclusion: This paper contributes to the leadership and creativity literatures by identifying the role of leader's behavior enhancing employee creative problem-solving behavior and the specific conditions strengthening the positive effect of leader feedback behavior on employee creative problem-solving behavior.

  • This paper deals with the energy saving problem of the follower aircraft in the loose leader-follower formation geometry in which the lateral separation between formation members is more than a wingspan of the leader aircraft. This formation geometry offers no drag benefit, but has a strategic advantage. In the case of loose formation flight, the follower aircraft usually consumes more energy than the leader aircraft because the follower aircraft should use more thrust to maintain given formation geometry, especially during the turning phase from the outside of the leader"s flight path or join-up phase. A formation control scheme based on the energy maneuverability is proposed in this paper. To design the proposed control law, the velocity command is designed using feedback linearization for the horizontal formation geometry and then coverts it to the altitude command using the energy equation. Numerical simulation is performed to verify the effectiveness of the proposed controller.

  • According to the characteristics of salvo attack for the multiple flight vehicles (MFV), the design of cooperative guidance law can be converted into the consensus problem of multi-vehicle system through the concept of multi-agent cooperative control. The flight vehicles can be divided into leader and followers depending on different functions, and the flight conditions of leader are independent of the ones of followers. The consensus problem of leader-follower multi-vehicle system is researched by graph theory, and the consensus protocol is also presented. Meanwhile, the finite time guidance law is designed for the flight vehicles via the finite time control method, and the system stability is also analyzed. Whereby, the guidance law can guarantee the line of sight (LOS) angular rates converge to zero in finite time, and hence the cooperative attack of the MFV can be realized. The effectiveness of the designed cooperative guidance method is validated through the simulation with a stationary target and a moving target, respectively.
