    PDϑ Control Strategy for a Fractional-Order Chaotic Financial Model.Changjin Xu, Maoxin Liao, Peiluan Li, Qimei Xiao & Shuai Yuan - 2019 - Complexity 2019:1-14.
    In this article, based on the previous works, a new fractional-order financial model is put up. The chaotic behavior of the fractional-order financial model is suppressed by designing an appropriatePDϑcontroller. By choosing the delay as the bifurcation parameter, we establish the sufficient condition to guarantee the stability and the existence of Hopf bifurcation of fractional-order financial model. Also, the influence of the delay and the fractional order on the stability and the existence of Hopf bifurcation of fractional-order financial model is (...)

  2. Different Effects of Supervisor Positive and Negative Feedback on Subordinate In-Role and Extra-Role Performance: The Moderating Role of Regulatory Focus.Weilin Su, Shuai Yuan & Qian Qi - 2022 - Frontiers in Psychology 12.
    As an important tool for supervisors to intervene subordinates’ work and influence their performance, supervisor feedback has gradually become a new academic research hotspot. In this study, we build and verify a theoretical model to explore the different effects of supervisor positive and negative feedback on subordinate in-role and extra-role performance, and the moderating role of regulatory focus in these relationships. With data from pairing samples of 403 Chinese employees and their direct supervisors, the results indicate that supervisor positive feedback (...)

  3. Discretion: Whether and How Does It Promote Street-Level Bureaucrats' Taking Charge Behavior?Shuai Yuan, Zhixia Chen & Mei Sun - 2022 - Frontiers in Psychology 13.
    The extant pieces of literature on discretion has mainly focused on its effect on policy implementation and public service delivery, but few studies have looked at its influence on street-level bureaucrats' work behavior, such as taking charge behavior, which is of great importance for government reforms, especially in developing and transitional countries. Based on the self-determination theory, this study examines whether and how discretion promotes street-level bureaucrats' TCB. Two studies were conducted among street-level bureaucrats in China. First, a survey experiment (...)
