We examined the impact of psychological empowerment on employee loyalty, satisfaction, and task performance with survey data from 617 employees a petrochemical company in China. Results based structural equation model showed that had significant positive effect both loyalty performance, which was partially mediated by satisfaction. In addition, we found significantly positively influenced each dimension internal marketing.

The aim of this study was to develop and validate a prediction model evaluate the risk poor sleep quality. We performed cross-sectional enrolled 1,928 college students from five universities between September November 2021. quality evaluated using Chinese version Pittsburgh Sleep Quality Index (PSQI). Participants were divided into training (n = 1,555) group validation 373) group. used establish model, predictive effectiveness model. classification all participants based on optimal threshold...

In this paper a new chaotic system is presented. Some of its basic dynamical properties are studied. An electronic circuit designed to realize the system. Experimental behavior found be identical predicted by theoretical analysis and numerical simulations. Based on Lyapunov stability theory, controlled method adaptive backstepping. Numerical simulation shows feasibility effectiveness approach.

This paper is involved with the adaptive control and synchronization problems for an uncertain new hyperchaotic Lorenz system. Based on Lyapunov stability theory, law derived such that trajectory of system unknown parameters can be globally stabilized to unstable equilibrium point uncontrolled Furthermore, approach presented synchronizations between two identical systems, particularly different systems. Numerical simulations show effectiveness method.

Purpose Product presentation plays a critical role in influencing consumers’ purchasing decisions online shopping. The purpose of this study is to examine the effects text-image information on product pages sales. This also specifically explores moderating celebrity endorsements relationship between and Design/methodology/approach based regression analysis using data sets from largest book retailer China, Dangdang.com. Findings results show that there an inverse U-shaped word count...

This paper focuses on the cluster synchronisation problem of coupled complex networks with uncertain disturbances under an adaptive fixed-time control strategy. To begin with, dynamical community structure which are subject to taken into account. Then, a novel strategy combined techniques is proposed guarantee nodes in communities desired states settling time. In addition, stability error systems theoretically proved based Lyapunov theorem. At last, two examples presented verify...

In this paper two different methods——active control synchronization method and adaptive are presented to study hyperchaotic Chen system Rssler with structure. Two controllers designed for synchronizing response drive system. When the parameters known in advance, active is adopted, simple without constructing Lyapunov function time which realizes short, when fully unknown, analytical expression of controller law given based on stability theory, makes systems reach identifies unknown...

This paper reports a new hyperchaotic system by adding an additional state variable into three-dimensional chaotic dynamical system. Some of its basic properties, such as the attractor, Lyapunov exponents, bifurcation diagram and attractor evolving periodic, quasi-periodic behaviours varying parameter k are studied. An effective nonlinear feedback control method is used to suppress hyperchaos unstable equilibrium. Furthermore, circuit designed realize this electronic workbench (EWB)....

This paper further investigates a new type synchronization called full state hybrid function projective (FSHFPS). Based on the Lyapunov stability theory, adaptive control law and parameter update laws are derived to make FSHFPS between two financial hyperchaotic systems. And of systems is first studied in this paper. The method successfully applied identical different when parameters unknown. Numerical simulations presented demonstrate effectiveness proposed controllers.

In this paper, we get a time-delay new financial hyperchaotic system by modifying an old system. study the stability of via adaptive periodically intermittent linear control method. Stability is obtained using Lyapunov theorem, update laws and differential inequalities. Moreover, some numerical simulations are performed to show advantage applications

This paper reports a new hyperchaotic system by adding an additional state variable into three-dimensional chaotic dynamical system, studies some of its basic properties, such as the attractor, Lyapunov exponents, bifurcation diagram and attractor evolving periodic, quasi-periodic behaviours varying parameter κ. Furthermore, effective linear feedback control method is used to suppress hyperchaos unstable equilibrium, periodic orbits orbits. Numerical simulations are presented show these results.

In this study, a successful linear matrix inequality approach is used to analyse non-parameter perturbation of multi-delay Hopfield neural network by constructing an appropriate Lyapunov-Krasovskii functional. This paper presents the comprehensive discussion and also extensive applications.

This paper reports the globally exponentially attractive set and synchronization problem of a new chaotic finance system. Firstly, based on definition Lyapunov stability theory, sufficient condition was given. Secondly, one control approaches is investigated. Sufficient conditions for exponential two systems are obtained analytically. Finally, numerical simulation results indicate effectiveness proposed methods.
