    The Effect of Workplace Negative Gossip on Employee Proactive Behavior in China: The Moderating Role of Traditionality.Xiangfan Wu, Ho Kwong Kwan, Long-Zeng Wu & Jie Ma - 2018 - Journal of Business Ethics 148 (4):801-815.
    In this study, we examined the relationship between workplace negative gossip, as perceived by the targets, and proactive behavior by focusing on the mediating role of the target’s emotional exhaustion and the moderating role of the target’s traditionality. Our results from dyadic data on 234 supervisor–subordinate relationships in China revealed that workplace negative gossip was negatively related to proactive behavior; emotional exhaustion mediated this relationship; and traditionality strengthened both the relationship between workplace negative gossip and emotional exhaustion and the indirect (...)

    Contextual Cueing Accelerated and Enhanced by Monetary Reward: Evidence From Event-Related Brain Potentials.Guang Zhao, Qian Zhuang, Jie Ma, Shen Tu & Shiyi Li - 2021 - Frontiers in Human Neuroscience 15.
    The vital role of reward in guiding visual attention has been supported by previous literatures. Here, we examined the motivational impact of monetary reward feedback stimuli on visual attention selection using an event-related potential component called stimulus-preceding negativity and a standard contextual cueing paradigm. It has been proposed that SPN reflects affective and motivational processing. We focused on whether incidentally learned context knowledge could be affected by reward. Both behavior and brain data demonstrated that contexts followed by reward feedback not (...)

  3. Altered Effective Connectivity in the Emotional Network Induced by Immersive Virtual Reality Rehabilitation for Post-Stroke Depression.Jia-Jia Wu, Mou-Xiong Zheng, Xu-Yun Hua, Dong Wei, Xin Xue, Yu-Lin Li, Xiang-Xin Xing, Jie Ma, Chun-Lei Shan & Jian-Guang Xu - 2022 - Frontiers in Human Neuroscience 16.
    Post-stroke depression is a serious complication of stroke that significantly restricts rehabilitation. The use of immersive virtual reality for stroke survivors is promising. Herein, we investigated the effects of a novel immersive virtual reality training system on PSD and explored induced effective connectivity alterations in emotional networks using multivariate Granger causality analysis. Forty-four patients with PSD were equally allocated into an immersive-virtual reality group and a control group. In addition to their usual rehabilitation treatments, the participants in the immersive-virtual reality (...)

    Linkboost: A Link Prediction Algorithm to Solve the Problem of Network Vulnerability in Cases Involving Incomplete Information.Chengfeng Jia, Jie Ma, Qi Liu, Yu Zhang & Hua Han - 2020 - Complexity 2020:1-14.
    The vulnerability of network information systems has attracted considerable research attention in various domains including financial networks, transportation networks, and infrastructure systems. To comprehensively investigate the network vulnerability, well-designed attack strategies are necessary. However, it is difficult to formulate a global attack strategy as the complete information of the network is usually unavailable. To overcome this limitation, this paper proposes a novel prediction algorithm named Linkboost, which, by predicting the hidden edges of the network, can complement the seemingly missing but (...)
