In this paper, two scaling matrices are used to research the synchronization of different dimensional chaotic systems with unknown parameters. Firstly, the definition of synchronization of chaotic systems with different dimensions is introduced. Secondly, based on Lyapunov stability theorem and adaptive control method, an adaptive feedback hybrid controller and parameter adaptive laws are designed to realize synchronization of uncertain chaotic systems with different dimensions. Finally, three numerical experiments are carried out to verify the effectiveness of the proposed method.

ABSTRACT By integrating theories of social learning and moral judgment, we developed a theoretical model on whether and when peers imitate employees’ unethical pro-organizational behavior in the workplace. The study, which involved 256 employees in a large manufacturing company in China, revealed that employees’ UPB positively predicted peers’ vicarious learning of UPB, with the effect strengthened by employees’ organizational tenure but weakened by peers’ deontic injustice. Moreover, the positive effect of employees’ UPB on their peers’ vicarious learning was mitigated, and (...) even turned negative when employees’ organizational tenure was low, but peers’ deontic injustice was high.

Objective: Pulmonary complications could badly affect the recovery of neurological function and neurological prognosis of neurological critically ill patients. This study evaluated the effect of high-flow nasal cannula therapy on decreasing pulmonary complications in neurologically critically ill patients.Patients and Methods: The patients admitted to the intensive care unit with serious neurological disease and receiving oxygen therapy were retrospectively reviewed. Patients were divided into the HFNC group and the conventional oxygen therapy group. We analyzed the data within these two groups, including (...) patients’ baseline data, short-term outcomes of respiratory complications, general outcomes including hospital stay, ICU stay and mortality, and neurological functions. To analyze the relevant factors, we performed multivariable logistic regression analysis.Results: A total of 283 patients met the criteria, including 164 cases in the HFNC group and 119 cases in the COT group. The HFNC group had remarkably less mechanical ventilation requirement with lower phlegm viscosity. Even more, ICU stay and total hospital stay were significantly shortened in the HNFC group.Conclusion: HFNC decreased pulmonary complications in neurologically critically ill patients and improved recovery of neurological function and neurological prognosis.

While prior literature has widely acknowledged that the entrepreneurial environment significantly fertilizes entrepreneurship, the impact of workplace receives limited attention, and the vital role of organizations in linking social entrepreneurial environment and employee entrepreneurship has been largely ignored. Therefore, this study aims to unfold how multiple entrepreneurial environments shape employee entrepreneurship and then further reveal how such relationships vary with employees’ risk propensity. Drawn on the theoretical lens of mindsponge process, which offers an explanation of why and how organizations and (...) individuals adopt new values through the cost-benefit analysis, we proposed a research model to explain the influence mechanisms of the social entrepreneurial environment on the cost-benefit analysis of both organizations and individual employees. Specifically, given that organizations deeply embedded in the society need to balance the costs and benefits under the pressure of the social entrepreneurial environment, the social entrepreneurial environment affects the organizational entrepreneurial environment. Similarly, employees’ cost-benefit analysis under the pressure of organizational hostility will influence their entrepreneurial intentions. Through analyzing the data collected from a two-wave survey with 220 employees, we showed that organizational hostility toward employee entrepreneurship plays a mediating role between social entrepreneurial environment and employees’ entrepreneurial intentions. In addition, such mediation relationship is moderated by coworkers’ unethical behaviors during their entrepreneurship and employees’ risk propensity, which are expected to influence organizations’ and employees’ cost-benefit analysis, respectively.

The virtual brand community has become an important marketing tool for companies. A successful brand community marketing strategy should attract a large number of consumers. Although past studies have revealed consumer motivations for participating in virtual brand communities, they fail to answer an important question: Why is it so easy for some virtual brand communities to attract users while others have such difficulty? In this study, product characteristics are hypothesized to be important factors that determine consumer motivation to participate in (...) brand communities. Product characteristics can directly affect how actively consumers participate in brand communities. The results of questionnaires show that product complexity, product symbolism, and product satisfaction have a positive influence on consumers’ willingness to participate in brand communities. Notably, the duration of product use has a regulating effect on the influence of product satisfaction and product symbolism. A long period of product use weakens the influence of product satisfaction on consumers’ willingness to participate in brand communities. On the contrary, a long period of product use strengthens the influence of product symbolism on consumers’ willingness to participate in brand communities. This study enriches the literature on brand community participation and has implications for companies that aim to utilize brand communities for marketing. (shrink)

This paper investigates the aperiodic sampled-data control for a chaotic system. Firstly, Takagi–Sugeno fuzzy models for the chaotic systems are established. The lower and upper bounds of the sampling period are taken into consideration. Then, the criteria for mean square exponential stability analysis and aperiodic sampled-data controller synthesis are provided by means of linear matrix inequalities. And the real sampling patterns can be fully captured by constructing suitable Lyapunov functions. Finally, an illustrative example shows that the proposed method is effective (...) to guarantee that the system’s states are stable with aperiodic sampled data. (shrink)

What responsibility do individuals bear for structural injustice? Iris Marion Young has offered the most fully developed account to date, the Social Connections Model. She argues that we all bear responsibility because we each causally contribute to structural processes that produce injustice. My aim in this article is to motivate and defend an alternative account that improves on Young’s model by addressing five fundamental challenges faced by any such theory. The core idea of what I call the “Role-Ideal Model” is (...) that we are each responsible for structural injustice through and in virtue of our social roles, i.e. our roles as parents, colleagues, employers, citizens, etc., because roles are the site where structure meets agency. In short, the Role-Ideal Model explains how individual action contributes to structural change, justifies demands for action from each particular agent, specifies what kinds of acts should be undertaken, moderates between demanding too much and too little of individual agents, and provides an account of the critical responses appropriate for holding individuals accountable for structural injustice.

The present study examined the effects of transcranial direct current stimulation using Halo Sport on the time to exhaustion in relation with muscle activities and corticomuscular coupling of agonist and antagonist muscles during a sustained isometric fatiguing contraction performed with the elbow flexors. Twenty healthy male college students were randomly assigned to tDCS group and control group. The two group participants performed two experimental sessions which consisted of pre-fatigue isometric maximal voluntary contraction, sustained submaximal voluntary contractions performed to exhaustion, and (...) post-fatigue MVC with the right elbow flexor muscles. Sham stimulation and tDCS were applied for control and tDCS group participants 20 min prior to the second session test, respectively. MVC strength in pre- and post-fatigue test, TTE, electroencephalogram, and electromyography of biceps brachii and triceps brachii were recorded during the tests. It was found that tDCS using the Halo Sport device significantly increased TTE and thus improved muscular endurance performance. The improvement may be partly related to the improvement of neuromuscular efficiency as reflected by decrease of antagonistic muscle coactivation activities, which may be related to cortical originated central processing mechanism of neuromuscular activities.

Chronic stress impairs working memory, but few studies have explored the protective factors of the impairment. We aimed to investigate the effect of self-awareness on WM processing in people under chronic stress. Participants under chronic stress completed an n-back task after a self-awareness priming paradigm during which electroencephalograms were recorded. The behavioral results showed that participants whose self-awareness was primed reacted faster and more accurately than the controls. Event-related potentials revealed the following P2 was more positive in the self-awareness group (...) than in the controls, indicating that self-awareness enhanced allocation of attention resources at the encoding stage. N2 was attenuated in the self-awareness group compared with the controls, indicating that smaller attention control efforts were required to complete WM tasks adequately after self-awareness priming; and enhanced late positive potential was evoked in the self-awareness group compared with the controls, suggesting self-awareness enabled participants to focus attention resources on the information at the maintenance stage. Critically, mediational analyses showed that LPP mediated the relationship between self-awareness and WM response times. This result suggests that the fact that participants whose self-awareness was primed were able to achieve better behavioral performances may be attributed to their mobilization of sustained attention resources at the maintenance stage. In summary, self-awareness exerted a protective effect on WM in those under chronic stress, which may be due to the enhancements in the allocation and mobilization of attention. These results could be used to develop more specific coping strategies for people under chronic stress. (shrink)

Most discussions of racial fetish center on the question of whether it is caused by negative racial stereotypes. In this paper I adopt a different strategy, one that begins with the experiences of those targeted by racial fetish rather than those who possess it; that is, I shift focus away from the origins of racial fetishes to their effects as a social phenomenon in a racially stratified world. I examine the case of preferences for Asian women, also known as ‘yellow (...) fever’, to argue against the claim that racial fetishes are unobjectionable if they are merely based on personal or aesthetic preference rather than racial stereotypes. I contend that even if this were so, yellow fever would still be morally objectionable because of the disproportionate psychological burdens it places on Asian and Asian-American women, along with the role it plays in a pernicious system of racial social meanings.
