Cyberloafing is prevalent in the workplace and research has increasingly focused on its antecedents. This study aims to extend the cyberloafing literature from the perspective of perceived overqualification among civil servants. Drawing on equity theory, we examined the effect of POQ on cyberloafing, along with the mediating role of harmonious passion on the POQ–cyberloafing relationship and the moderating role of the need for achievement on strengthening the link between POQ and harmonious passion. Using time-lagged data from a sample of 318 (...) civil servants in China, we found that POQ was positively related to cyberloafing; harmonious passion mediated this relationship; the need for achievement moderated the effect of POQ on harmonious passion as well as the indirect effect of POQ on cyberloafing via harmonious passion. Based on the findings, we discussed theoretical and managerial implications and provided future research avenues. (shrink)

This paper focuses on the problem of event-triggered control for a class of uncertain nonlinear strict-feedback systems with zero dynamics via backstepping technique. In the design procedure, the adaptive controller and the triggering event are designed at the same time to remove the assumption of the input-to-state stability with respect to the measurement errors. Besides, we propose an assumption to deal with the problem of zero dynamics. Three different event-triggered control strategies are designed, which guarantees that all the closed-loop signals (...) are globally bounded. The effectiveness of the proposed methods is illustrated and compared using simulation examples. (shrink)

As an essential component and core power source of aircraft, the operational stability of aeroengine has important impact on system safety and reliability. Accurate degradation tendency prediction on an engine can not only improve its operational stability but also significantly reduce the maintenance costs. In this paper, a novel forecasting method that combines CEEMDAN permutation entropy and improved Grey–Markov model is proposed to perform multistep degradation tendency prediction of aircraft engines. In order to accurately quantify the degradation level of engines, (...) a new integrated degradation index is innovatively designed by multidimensional sensory data. And then, because of high speed and excellent performance, CEEMDAN algorithm is specifically employed to decompose the generated IDI series to eliminate the potential influence of stochastic fluctuations. Aiming at the complexity of intrinsic mode functions generated by CEEMDAN, an IMFs reconstruction strategy based on permutation entropy is developed to better characterize the degradation states. Finally, on the basis of above achievements and for higher forecasting efficiency and accuracy, an improved Grey–Markov model combined with the moving window algorithm, which is unique, is constructed to realize multistep degradation trend prediction of engines. The proposed method is applied to the degradation tendency prediction of aircraft engines. The experimental results validate the effectiveness and superiority of the proposed method, and it is more suitable for engineering applications in comparison with other methods. (shrink)

Despite the rising interest in environmental strategies, few studies have examined how managerial cognition of such strategies influences actual innovation capability development. Taking a managerial cognition perspective, this study investigates how managers’ perceptions of institutional pressures relate to their focus on proactive environmental strategy, which in turn affects firms’ realized innovation capability. The findings from a primary survey and three secondary datasets of publicly listed companies in China reveal that managers’ perceived business and social pressures are positively associated with their (...) focus on proactive environmental strategy, which consequently fosters innovation capability development. Moreover, state ownership and government administrative control weaken the impact of managerial focus on proactive environmental strategy on innovation capability. These findings have important implications for how managerial cognition supports environmental strategy and organizational capability building under the influence of institutional pressures and government intervention.

Despite the growing importance of stakeholder management, few studies have empirically examined the influence of stakeholder relationship capability on firm innovation, especially in emerging economies. This study investigates how SRC relates to firm innovation in the presence of governmental intervention and in combination with firm-level characteristics. Using a survey and multiple secondary datasets on the listed Chinese firms, our findings indicate that SRC is positively associated with firm innovation. Moreover, advanced legal development and high-tech status strengthen the positive link between (...) SRC and innovation, whereas state ownership and firm age weaken this relationship. These findings provide novel insights into how firms use stakeholder management to enhance innovation that is beneficial for economic growth. (shrink)
