This paper is expected to introduce a novel memductor-based chaotic system. The local dynamical entities, such as the basic dynamical behavior, the divergence, the stability of equilibrium set, and the Lyapunov exponent, are all investigated analytically and numerically to reveal the dynamic characteristics of the new memductor-based chaotic system as the system parameters and the initial state of memristor change. Subsequently, an active control method is derived to study the synchronous stability of the novel memductor-based chaotic system through making the (...) synchronization error system asymptotically stable at the origin. Further to these, a memductor-based chaotic circuit is designed, realized, and applied to construct a new memductor-based secure communication circuit by employing the basic electronic components and memristor. Furthermore, the design principle of the memductor-based chaotic circuit is thoroughly analyzed and the concept of “the memductor-based chaotic circuit defect quantification index” is proposed for the first time to verify whether the chaotic output is consistent with the mathematical model. A good qualitative agreement is shown between the simulations and the experimental validation results. (shrink)

IntroductionIn recent years, with the popularity of many social media platforms worldwide, the role of “virtual social network platforms” in the field of cross-cultural communication has become increasingly important. Scholars in psychology and neuroscience, and cross-disciplines, are attracted to research on the motivation, mechanisms, and effects of communication on social media across cultures.Methods and AnalysisThis paper collects the co-citation of keywords in “cultural psychology,” “cross-culture communication,” “neuroscience,” and “social media” from the database of web of science and analyzes the hotspots (...) of the literature in word cloud.ResultsBased on our inclusion criteria, 85 relevant studies were extracted from a database of 842 papers. There were 44 articles on cultural communication on social media, of which 26 were from the perspective of psychology and five from the perspective of neuroscience. There are 27 articles that focus on the integration of psychology and neuroscience, but only a few are related to cross-cultural communication on social media.ConclusionScholars have mainly studied the reasons and implications of cultural communication on social media from the perspectives of cultural psychology and neuroscience separately. Keywords “culture” and “social media” generate more links in the hot map, and a large number of keywords of cultural psychology and neuroscience also gather in the hot map, which reflects the trend of integration in academic research. While cultural characteristics have changed with the development of new media and virtual communities, more research is needed to integrate the disciplines of culture, psychology, and neuroscience.

Learner control is an important instructional design in video-based learning. This study assessed two conditions: a full learner control where learners direct their learning path, and a hybrid learner control where learners follow the instructor-set path but still enjoy certain aspects of control. Two groups of university students participated in this study by learning statistics through online video courses. The findings show that the full learner control condition attained higher learning performance than the hybrid learner control condition, but spent more (...) time than the latter. The full learner control condition scored higher than the hybrid condition in the difficult sections of video-based learning; but no significant difference was found in the easy section. There was a significant difference between the two conditions in learning agency, but no differences in cognitive load and affective and cognitive engagement. Hierarchical regression analysis indicated differences between the full and the hybrid learner control conditions in the factors predicting overall scores. The findings carry important contributions and implications for the research and practice of instructional designs in online video-based learning such as MOOCs. (shrink)

This study aims to investigate the impact of justice perception of the employees on three dimensions of employee-based brand equity under the mediating role of psychological contract fulfillment. For this purpose, data have been collected from the employees of the education industry under the convenience sampling technique. In this regard, a survey method was used, and questionnaires were distributed among 420 respondents, out of which 310 questionnaires were received back, and after discarding 32 partially filled questionnaires, useable responses were left. (...) Data have been analyzed through structural equation modeling, and the partial least square -SEM approach has been used in this regard through the Smart PLS software. Measurement and structural models were assessed, and all the indicators of reliability and validity have been found to be fit. Path estimation indicates that perception of justice promotes brand endorsement and brand allegiance, while the relationship of perception of justice and brand-consistent behavior has not been found statistically significant. Moreover, it has also been found that perception of justice ensures employees that their psychological contract has been met. In addition, psychological contract fulfillment has found a mediating mechanism between the perception of justice and the three dimensions of EBBE. (shrink)

In the context of the COVID-19, we examined the relationship between college students’ ego depletion and their prosocial behavior. We explored the mediating role of social self-efficacy between ego depletion and prosocial behavior, we also examined the moderating role of personal belief in a just world in this relationship. 1,122 college students completed the ego depletion questionnaire, prosocial behavior questionnaire, social self-efficacy questionnaire, and personal belief in a just world questionnaire. The current findings suggested that: Social self-efficacy mediated the relationship (...) between college students’ ego depletion and their prosocial behaviors. The ego depletion of college students could be used to predict their prosocial behavior through social self-efficacy. Personal belief in a just world moderated the relationship between social self-efficacy and prosocial behavior. (shrink)

BackgroundTemporal interference (TI) stimulation is a novel technique that enables the non-invasive modulation of deep brain regions. However, the implementation of this technology in humans has not been well-characterized or examined, including its safety and feasibility.ObjectiveWe aimed to examine the feasibility, safety, and blinding of using TI on human participants in this pilot study.Materials and methodsIn a randomized, single-blinded, and sham-controlled pilot study, healthy young participants were randomly divided into four groups [TI and transcranial alternating current stimulation (tACS) targeting the (...) right frontoparietal region, TI-sham, and tACS-sham]. Each participant was asked to complete N-back (N = 1 to 3) tasks before, during, and after one session of stimulation to assess their working memory (WM). The side effects and blinding efficacy were carefully assessed. The accuracy, reaction time (RT), and inverse efficiency score (IES, reaction time/accuracy) of the N-back tasks were measured.ResultsNo severe side effects were reported. Only mild-to-moderate side effects were observed in those who received TI, which was similar to those observed in participants receiving tACS. The blinding efficacy was excellent, and there was no correlation between the severity of the reported side effects and the predicted type of stimulation that the participants received. WM appeared to be only marginally improved by TI compared to tACS-sham, and this improvement was only observed under high-load cognitive tasks. WM seemed to have improved a little in the TI-sham group. However, it was not observed significant differences between TI and TI-sham or TI and tACS in all N-back tests.ConclusionOur pilot study suggests that TI is a promising technique that can be safely implemented in human participants. Studies are warranted to confirm the findings of this study and to further examine the effects of TI-sham stimulation as well as the effects of TI on deeper brain regions. (shrink)

This study takes the mountainous villages in central Shandong as the research object, which becomes the entry point for studying the concepts of cultural landscape and revitalization. This study examines some villages with special cultural landscapes due to their unique physical space. Later, due to industrialization, they suffered a cultural crisis and then revitalized after restoration, and then reused it to generate value. It explores the interdependent relationship between the natural environment, people, and society in the mountainous area, including the (...) spatial production and value reuse of the village cultural landscape. Through this study, not only the theoretical connotation of concepts such as cultural landscape and spatial production is enriched, but also the intrinsic connection between the characteristics of village cultural landscape and revitalization is revealed. At the same time, the study also proposed new knowledge about value reuse and revitalization, that is, things in the past can not only retain their old value in the present but also generate new value. This study will further enrich the content of the theoretical research on cultural landscape and revitalization and help to understand the revitalized villages worldwide. (shrink)

With the global pandemic of COVID-19, it has been striking psychological burdens on individuals. Under this background, more and more people get wellbeing by watching live broadcasts. However, the psychological mechanism behind this phenomenon is still a black box. This study finds that when people watch a live broadcast and interact with anchors and other people, an interaction ritual chain is formed, and emotional energy is generated, thus making people experience and understand the meaning of the live interaction ritual chains. (...) Under the effect of the meaning transfer model, people will generate wellbeing. Specifically, the basic meaning of live interaction drives people’s generation of wellbeing. The meanings of self-participation, self-display, self-concept, and self-renewal play a role in mediation in enhancing people’s wellbeing with the basic meaning of live broadcast interaction.

This study adopts qualitative research methods, and the research texts are three Zhang Yimou films that reflect the history and social culture of the Republic of China, namely Red Sorghum, Ju Dou, and Raise the Red Lantern, also known as the Red Trilogy. This study explores the phenomenon of consuming history through the art form of films. The study finds that history is not only concerned and used by historians and archaeologists but can also be used by artists and consumed (...) by the audience. The consumption (use) of history by artists and audiences is not consuming its complete authentic history. In Zhang Yimou's Red trilogy films, the history and social culture of the Republic of China are arranged and designed. The audience can get a feeling that goes straight to the heart by watching these artfully processed. Re-made history, which is different from the historical knowledge read through words in history books, this kind of consumption is more intuitive, attractive, and acceptable to the audience. By watching these films, the audience colloquially learns about history, and although it is not a serious and complete history, it gains cultural value just as much. (shrink)

Previous studies have demonstrated that orientation-specific deprivation in early life can lead to neural deficits of spatial vision in certain space, and can even result in meridional amblyopia. Individuals with astigmatism are the optimal and natural models for exploring this asymmetric development of spatial vision in the human visual system. This study aims to assess the contrast sensitivity function and EEG signals along two principal meridians in participants with regular astigmatism when being optimal optical corrected. Twelve participants with astigmatism and (...) thirteen participants with were recruited in the current study. CSFs and spatial sweep visual evoked potentials were measured with vertical and horizontal sinewave gratings along two principal meridians monocularly. Area under log CSF, spatial frequency threshold corresponding to 80% contrast gratings, and CSF acuity were calculated from CSF test. In addition, sVEP amplitudes and thresholds were calculated with the recursive least square method. Participants with astigmatism exhibited marked vertical-horizontal resolution disparities even after they were corrected with optimal optical corrections. CSF tests showed that AULCSF along weak meridian was lower than that along strong meridian in both groups. Significant meridional disparity of CSF acuity was also found in both groups. In addition, the MA group showed larger meridional disparity compared to the AST group. Spatial sVEP thresholds also supported the existence of marked meridional disparity. Our results suggest that meridian-specific partial deprivation in early life might lead to monocularly asymmetric development of spatial vision in the human visual system. In terms of application, we tested the feasibility and reliability of adopting psychophysical and EEG scalings to investigate the asymmetric development of spatial vision related to astigmatism. These paradigms are potentially applicable to reduce and even eliminate the meridional disparity in the primary visual cortex by adopting perceptual learning or other vision-related interventions.

Brain-computer interface based on steady-state visual evoked potential has been widely studied due to the high information transfer rate, little user training, and wide subject applicability. However, there are also disadvantages such as visual discomfort and “BCI illiteracy.” To address these problems, this study proposes to use low-frequency stimulations, which can simultaneously elicit visual evoked potential and pupillary response to construct a hybrid BCI system. Classification accuracy was calculated using supervised and unsupervised methods, respectively, and the hybrid accuracy was obtained (...) using a decision fusion method to combine the information of VEP and PR. Online experimental results from 10 subjects showed that the averaged accuracy was 94.90 ± 2.34% for the supervised method and 91.88 ± 3.68% for the unsupervised method, which correspond to the ITR of 64.35 ± 3.07 bits/min and 33.19 ± 2.38 bpm, respectively. Notably, the hybrid method achieved higher accuracy and ITR than that of VEP and PR for most subjects, especially for the short data length. Together with the subjects’ feedback on user experience, these results indicate that the proposed h-BCI with the low-frequency stimulation paradigm is more comfortable and favorable than the traditional SSVEP-BCI paradigm using the alpha frequency range.

Megaprojects are implemented by different organisations, such as owners, consultants, and contractors. Gradually, these organisations and their connections can form business networks that influence both the market position of individual organisations and project performance. Previous research on large-scale projects mainly focused on static and homogeneous networks that were constructed by one individual project and/or carried out over one-off collaboration. However, this neglected the consideration of project network diversity, as well as repetitive, dynamic, cross-project coopetition relationship and long-term business networks formed (...) by key actors. Here, we chose Chinese skyscrapers over 300 meters that were built from 1996 to 2015 as typical megaproject cases and analysed the formation and evolution of megaproject business networks from the perspective of interorganisational coopetition. We identified the key actors involved and empirically studied their dynamic network positions over time. The main contributions of this study are threefold. First, we found that past collaboration experience has direct and dynamic impacts on the formation of megaproject business networks. Second, we identified key actors in the interorganisational business network and unveiled their dynamic positions with clear patterns. Third, we highlighted the temporal-spatial effect on the formation and development of business networks, alongside developments in the megaproject market. The findings of this study also provide practical applications for owners to choose collaboration partners and to build high-performance teams and for suppliers to enter and sustain the business in the megaprojects networks.

ABSTRACT In the context of the COVID-19 pandemic, leaders are facing an ethical dilemma and a tense tradeoff between employees’ health and economic performance. From the perspective of employees’ perceptions of the work situation, this study examines the way ethical leadership enhances employee creativity during the COVID-19 pandemic by using leader-member exchange and organizational ethical climate as mediators. The sample included 308 supervisor-employee pairs from 20 high-tech companies in eight provincial regions of China. Structural equation modeling was used to test (...) the proposed hypotheses. Results indicate that ethical leadership can significantly enhance employee creativity through the fully mediating roles of employees’ perceptions of leader-member exchange and organizational ethical climate. Moreover, leader-member exchange affects employee creativity directly as well as indirectly through the mediating role of organizational ethical climate. This study offers insights into the process linking ethical leadership to employee creativity and provides practical suggestions on ways of enhancing employee creativity in situations like the COVID-19 pandemic crisis.

An accumulating amount of research has documented the harmful effects of abusive supervision on either its victims or third parties (peer abusive supervision). The abusive supervision literature, however, neglects to investigate the spillover effects of abusive supervision through third-party employees’ (i.e., peers’) mistreatment actions toward victims. Drawing on social learning theory, we argue that third parties learn mistreatment behaviors from abusive leaders and then themselves impose peer harassment and peer ostracism on victims, thereby negatively affecting victims’ performance. Further, we posit (...) that, if a victim has a proactive personality, this will weaken these indirect, negative effects. We conducted two studies, both with three-wave longitudinal data, to verify the hypotheses. The results of Study 1 evidence the significant indirect effects of abusive supervision on employee creative performance via both peer harassment and peer ostracism. Contrary to our moderation hypothesis, the analysis shows that victims’ proactive personality strengthens rather than weakens the negative indirect effects of peer harassment. Study 2 generally replicated the results of Study 1 with employee’s objective job performance as outcome. Our research contributes to the abusive supervision literature by highlighting a social learning process of third-party peer mistreatment, suggesting a spillover channel of abusive supervision on the victim’s performance.

People are known for good predictions in domains they have rich experience with, such as everyday statistics and intuitive physics. But how well can they predict for problems they lack experience with, such as the duration of an ongoing epidemic caused by a new virus? Amid the first wave of COVID-19 in China, we conducted an online diary study, asking each of over 400 participants to predict the remaining duration of the epidemic, once per day for 14 days. Participants’ predictions (...) reflected a reasonable use of publicly available information but were meanwhile biased, subject to the influence of negative affect and future time perspectives. Computational modeling revealed that participants neither relied on prior distributions of epidemic durations as in inferring everyday statistics, nor on mechanistic simulations of epidemic dynamics as in computing intuitive physics. Instead, with minimal experience, participants’ predictions were best explained by similarity-based generalization of the temporal pattern of epidemic statistics. In two control experiments, we further confirmed that such cognitive algorithm is not specific to the epidemic scenario and that minimal and rich experience do lead to different prediction behaviors for the same observations. We conclude that people generalize patterns in recent history to predict the future under minimal experience. (shrink)

This study focuses on CEO hubris and its effect on corporate unethical behaviour—pollution in particular, and in addition examines critical institutional contingencies [state ownership, political connection and industrial competition] which may moderate this effect. With data from over-polluting listed firms based on the real-time pollution monitoring system in transitional China from 2015 to 2017, we find that CEO hubris is significantly positively related to firm pollution, and that the moderating role of SO is not significant, that PC positively moderates the (...) hubris–pollution relationship and that industrial competition negatively moderates this relationship. These findings contribute to research on the upper echelon theory, institutional theory and the growing literature on emerging economies. (shrink)

As environmental issues have become increasingly prominent around the world, corporate environmental responsibility has begun to attract more attention. As the decision-makers of firms, top executives play an important role in the environmentally ethical behavior of their corporations. Few studies, however, have explored the motivations behind corporations’ environmentally responsible behavior from the perspective of how CEOs’ early experiences shape their decisions. This paper explores the impact that CEOs who experienced the Send-down movement have on their companies’ environmentally responsible behavior and (...) the boundary conditions of this impact from the perspective of the imprinting theory. Based on the data of listed Chinese companies from 2009 to 2020, we have found that CEOs who were themselves “Sent-down youth” have a positive impact on corporate environmental responsibility. For firms with a higher proportion of state ownership and CEOs with Chinese Communist Party membership, the relationship between experience with the Send-down movement and corporate environmental responsibility is strengthened, whereas a higher level of market competition weakens the relationship. This article enriches and deepens the research on the imprinting theory, and it also has certain practical implications for firms that hire top executives with unique types of early experiences to promote business ethics improvement.

Coal mine safety management involves many interested parties and there are complex relationships between them. According to game theory, a multiparty evolutionary game model is established to analyze the selection of strategies. Then, a simplified three-party model is taken as an example to carry out detailed analysis and solution. Based on stability theory of dynamics system and phase diagram analysis, this article studies replicator dynamics of the evolutionary model to make an optimization analysis of the behaviors of those interested parties (...) and the adjustment mechanism of safety management policies and decisions. The results show how the charge of supervision of government department and inspection of coal mine enterprise impact the efficiency of safety management and the effect of constraint measures and incentive and other measures in safety management.

This study investigates how social capital affects managers’ use of corporate resources. We find that for firms located in U.S. counties with a high level of social capital, (i) corporate cash holdings have higher marginal value, (ii) the contribution of capital expenditures to shareholder value is higher, and (iii) acquirers experience higher announcement-period abnormal stock returns. We further find that social capital decreases both over- and under-investment, and thus improves ex post corporate investment efficiency. Our evidence suggests that in communities (...) with a high level of social capital, strong social norms and dense social networks constrain unethical corporate behavior, which induces more efficient use of corporate resources.

An adaptive neural network control problem is addressed for a class of nonlinear hydraulic servo-systems with time-varying state constraints. In view of the low precision problem of the traditional hydraulic servo-system which is caused by the tracking errors surpassing appropriate bound, the previous works have shown that the constraint for the system is a good way to solve the low precision problem. Meanwhile, compared with constant constraints, the time-varying state constraints are more general in the actual systems. Therefore, when the (...) states of the system are forced to obey bounded time-varying constraint conditions, the high precision tracking performance of the system can be easily realized. In order to achieve this goal, the time-varying barrier Lyapunov function is used to prevent the states from violating time-varying constraints. By the backstepping design, the adaptive controller will be obtained. A radial basis function neural network is used to estimate the uncertainties. Based on analyzing the stability of the hydraulic servo-system, we show that the error signals are bounded in the compacts sets; the time-varying state constrains are never violated and all singles of the hydraulic servo-system are bounded. The simulation and experimental results show that the tracking accuracy of system is improved and the controller has fast tracking ability and strong robustness. (shrink)

This study was conducted to investigate the relationship between posttraumatic growth, resilience, positive coping style, and self-efficacy among the primary caregivers of children with developmental disorders in Chongqing, China. A total of 198 primary caregivers aged from 22 to 66 years old, including 155 females and 43 males, were enrolled. The Posttraumatic Growth Inventory, Connor-Davidson Resilience Scale-10, Simplified Coping Style Questionnaire, and General Self-Efficacy Scale were used for data collection. The results found that PTG could be positively predicted by resilience. (...) Positive coping style and self-efficacy mediated the relationship between resilience and PTG. The different levels of PTG were determined by the resident location, monthly income and education of the primary caregivers. The results suggest that it is critical to improve the mental health of the primary caregivers of children with developmental disabilities. Our results also provide a scientific basis for future research. (shrink)

Attention has been theorized as a system comprising three networks that can be estimated reliably by the attention network test ; the three networks are defined as alerting, orienting, and conflict control. The present study aims to identify the attention networks that are crucial for elite shooting and archery athletes and to examine whether mindfulness training can improve elite athletes' attention networks. We compared the performances in ANT between 62 elite athletes from the Chinese national team of shooting and archery (...) and 49 athletes from a provincial team in China. The results indicate three well-functioned attention networks in both groups, but elite athletes in the national team responded faster overall than athletes in the provincial team. The 62 elite athletes in the national team then received mindfulness training with varied periods ranging from 5 to 8 weeks, after which the ANT was re-administered. After mindfulness training, the elite athletes improved in orienting and conflict control networks compared with their pre-training performances. These results suggest that elite shooting and archery athletes in the national team are more efficient in all three attention networks, which means that they are able to reach the alerting state faster, make better use of environmental information, and suppress interference from distractors more efficiently. Moreover, the orienting and conflict control networks of the elite shooting and archery athletes can be improved by mindfulness training. We conclude that mindfulness practice should be considered as a useful addition to daily training for shooting and archery athletes. (shrink)

Stock price data have the characteristics of time series. At the same time, based on machine learning long short-term memory which has the advantages of analyzing relationships among time series data through its memory function, we propose a forecasting method of stock price based on CNN-LSTM. In the meanwhile, we use MLP, CNN, RNN, LSTM, CNN-RNN, and other forecasting models to predict the stock price one by one. Moreover, the forecasting results of these models are analyzed and compared. The data (...) utilized in this research concern the daily stock prices from July 1, 1991, to August 31, 2020, including 7127 trading days. In terms of historical data, we choose eight features, including opening price, highest price, lowest price, closing price, volume, turnover, ups and downs, and change. Firstly, we adopt CNN to efficiently extract features from the data, which are the items of the previous 10 days. And then, we adopt LSTM to predict the stock price with the extracted feature data. According to the experimental results, the CNN-LSTM can provide a reliable stock price forecasting with the highest prediction accuracy. This forecasting method not only provides a new research idea for stock price forecasting but also provides practical experience for scholars to study financial time series data. (shrink)
