Security issue against different attacks is the core topic of cyberphysical systems. In this paper, optimal control theory, reinforcement learning, and neural networks are integrated to provide a brief overview of optimal robust control strategies for a benchmark power system. First, the benchmark power system models with actuator and sensor attacks are considered. Second, we investigate the optimal control issue for the nominal system and review the state-of-the-art RL methods along with the NN implementation. Third, we propose several robust control (...) strategies for different types of cyberphysical attacks via the optimal control design, and stability proofs are derived through Lyapunov theory. Furthermore, the stability analysis with the NN approximation error, which is rarely discussed in the previous works, is studied in this paper. Finally, two different simulation examples demonstrate the effectiveness of our proposed methods. (shrink)

Schizophrenia is a serious mental disease whose pathogenesis has not been fully elucidated. Its clinical evaluation and diagnosis still highly depend on the clinical experience of doctors. It is of great scientific value and clinical significance to study the inducing factors and neuropathological mechanism of schizophrenia. Based on the four research problems of schizophrenia, this paper analyzes the data types that need to be stored in clinical trials and scientific research, including basic information, case report data, neuropsychological and cognitive function (...) evaluation, magnetic resonance data, electroencephalogram data, and intestinal flora data. Through the demand analysis of the system, including the data management part, data analysis part, the functional demand of the system management part, and the overall nonfunctional demand of the system, the overall architecture design, functional module division, and database table structure design of the system are completed. Adopting Browser/Server architecture and front-end and back-end separation mode and applying Java and Python programming language, based on spring framework and database, a multidimensional information management system for schizophrenia is designed and implemented, which includes four modules: data analysis, data management, system management, and security control. In addition, each functional module of the system is designed and implemented in detail, and the software operation flow of each module is illustrated with the sequence diagram. Finally, the multidimensional data of schizophrenia collected in our laboratory were used for system test to verify whether the system can meet the needs of clinical big data management of schizophrenia and the multidimensional information management system of schizophrenia can meet the needs of clinical big data management. The information management system helps schizophrenic researchers to carry out data management and data analysis. It also has advantages that are easy to use, safe, and efficient and has strong scalability in data management, data analysis, and scalability. It reflects the innovation of the system and provides a good platform for the management, research, and analysis of clinical big data of schizophrenia. (shrink)

The linguistic input children receive across early childhood plays a crucial role in shaping their knowledge about the world. To study this input, researchers have begun applying distributional semantic models to large corpora of child‐directed speech, extracting various patterns of word use/co‐occurrence. Previous work using these models has not measured how these patterns may change throughout development, however. In this work, we leverage natural language processing methods—originally developed to study historical language change—to compare caregivers' use of words when talking to (...) younger versus older children. Some words' usage changed more than others; this variability could be predicted based on the word's properties at both the individual and category levels. These findings suggest that caregivers' changing patterns of word use may play a role in scaffolding children's acquisition of conceptual structure in early development. (shrink)

This study examines the effectiveness of the inoculation strategy in countering vaccine-related misinformation among Hong Kong college students. A three-phase between-subject experiment was conducted to compare the persuasive effects of inoculation messages, supportive messages, and no message control. The results show that inoculation messages were superior to supportive messages at generating resistance to misinformation, as evidenced by more positive vaccine attitudes and stronger vaccine intention. Notably, while we expected the inoculation condition would produce more resistance than the control condition, there (...) was little evidence in favor of this prediction. Attitudinal threat and counterarguing moderated the experimental effects; issue involvement and political trust were found to directly predict vaccine attitudes and intention. The findings suggest that future interventions focus on developing preventive mechanisms to counter misinformation and spreading inoculation over the issue is an effective strategy to generate resistance to misinformation. Interventions should be cautious about using health advocacy initiated by governments among populations with low political trust. (shrink)

This article treats the public display of emotion as social performance. The concept of "emotive performance" is developed to highlight the overlooked quality of performativity in the social use of emotion. We argue that emotive performance is reflexive, cultural, and communicative. As an active social act, emotive performance draws from the cultural repertoire of interpretative frameworks and dominant narratives. We illustrate the utility of the concept by analyzing two episodes of unrehearsed emotive performances by two well-known politicians, Bill Clinton and (...) Jiang Zemin. The two cases demonstrate how emotion can be analyzed as a domain in which culturally specific narratives and rhetorics are used to advance the situational agenda of actors. The concept opens up a more expansive research agenda for sociology. It pushes sociologists to pay greater attention to people's experiences, interpretations, and deployments of emotions in social life. (shrink)

GIS is important equipment in the substation system in a complex microgrid network. Due to the long-term service in harsh operation environments, the electrical performance of GIS equipment will be seriously affected. Therefore, the regular maintenance of GIS equipment in the substation system is a routine task so as to ensure the normal operation of the microgrid networks. The traditional method relies on manual labor, where not only with the low operation efficiency but also regarding some maintenance, labors cannot reach (...) the inside of the GIS equipment, which seriously restricted the completion of GIS equipment maintenance operation. Based on the above analysis, a basic configuration of a GIS equipment maintenance robot with smart structure, convenient control, and stable motion characteristic has been proposed in this paper. Through the optimization design of the chassis adsorption system, the GIS inspection robot can achieve hanging and vertical adsorption inside the GIS equipment and some special motion status. In this way, the entire GIS equipment can be inspected without blind spots. Through establishing the mechanical model of the GIS inspection robot under the hanging and vertical motion state, the robustness and stability of the GIS inspection robot in the special status have been analyzed, and the corresponding GIS inspection robot robust stability motion control method has also been proposed. Finally, through the integrated design of mechanical system and hardware and software control system, the GIS inspection robot physical prototype system has been developed and the maintenance operation experiment has been carried out in Hunan Electric Power Company Maintenance Company through simulating the internal GIS equipment. The physical prototype can realize the basic movement and special movement in internal GIS equipment without any blind spots and complete the inspection task of GIS equipment operation; the movement of GIS robot is dexterous and stable in the whole operation process, which has strong robust stability. The research of GIS inspection robot in the complex microgrid networks has important theoretical significance and practical application value for the intelligent operation and maintenance management of substation system in complex microgrid networks.

Data Transfer Service (DTS) is an open-source project that is developing a document-centric message model for describing a bulk data transfer activity, with an accompanying set of loosely coupled and platform-independent components for brokering the transfer of data between a wide range of (potentially incompatible) storage resources as scheduled, fault-tolerant batch jobs. The architecture scales from small embedded deployments on a single computer to large distributed deployments through an expandable ‘worker-node pool’ controlled through message-orientated middleware. Data access and transfer efficiency (...) are maximized through the strategic placement of worker nodes at or between particular data sources/sinks. The design is inherently asynchronous, and, when third-party transfer is not available, it side-steps the bandwidth, concurrency and scalability limitations associated with buffering bytes directly through intermediary client applications. It aims to address geographical–topological deployment concerns by allowing service hosting to be either centralized (as part of a shared service) or confined to a single institution or domain. Established design patterns and open-source components are coupled with a proposal for a document-centric and open-standards-based messaging protocol. As part of the development of the message protocol, a bulk data copy activity document is proposed for the first time. (shrink)

Using data collected at two phases, this study examines why and how ethical leadership behavior influences employees’ evaluations of organization-focused justice, i.e., procedural justice and distributive justice. By proposing ethical leaders as moral agents of the organization, we build up the linkage between ethical leadership behavior and the above two types of organization-focused justice. We further suggest trust in organization as a key mediating mechanism in the linkage. Our findings indicate that ethical leadership behavior engenders employees’ trust in their employing (...) organization, which in turn promotes their justice perceptions toward the organization. The theoretical and practical implications of these findings are discussed, and some directions for future research are suggested. (shrink)

In this article, drawing from a relational perspective, we explore the relationship between moral leadership and employee creativity, treat employee identification with leader and leader–member exchange as two mediators, and develop a new theoretical model of employee creativity. Our data collected from 160 supervisor–subordinate dyads in the People’s Republic of China demonstrate that moral leadership is positively related to both employee identification with leader and LMX. Further, employee identification with leader partially mediates the relationship between moral leadership and LMX. In (...) particular, employee identification with leader greatly enhances LMX which leads to high creativity. Overall, the relationship between moral leadership and employee creativity is mediated by not only employee identification with leader but also LMX. Our findings offer a new theoretical framework for future theory development and testing on creativity as well as practical implications for researchers and managers in business ethics. (shrink)

In recent years, foreign language learning has been proposed as a possible cognitive intervention for older adults. However, the brain network and cognitive functions underlying FLL has remained largely unconfirmed in older adults. In particular, older and younger adults have markedly different cognitive profile—while older adults tend to exhibit decline in most cognitive domains, their semantic memory usually remains intact. As such, older adults may engage the semantic functions to a larger extent than the other cognitive functions traditionally considered the (...) most important. Using anatomical measurements and a cognitive test battery, the present study examined this hypothesis in twenty cognitively normal older adults, who participated in a two-month Italian learning programme. Results showed that the immediate learning success and long-term retention of Italian vocabularies were most consistently predicted by the anatomical measures of the left pars orbitalis and left caudal middle frontal cortex, which are implicated in semantic and episodic memory functions. Convergent evidence was also found based on the pattern of cognitive associations. Our results are consistent with a prominent role of semantic and episodic memory functions in vocabulary learning in older learners. (shrink)

Revenge is common in our daily lives, and people feel good when engaging in revenge behavior. However, revenge behavior is a complex process and remains somewhat of a puzzle of human behavior. Neuroimaging studies have revealed that revenge behaviors are associated with activation of a neural network containing the anterior cingulate cortex, ventral striatum, inferior frontal gyrus, and dorsolateral prefrontal cortex. Recent brain stimulation research using transcranial direct current stimulation and transcranial magnetic stimulation has shown a causal relationship between brain (...) regions and revenge behaviors, but the findings have been mixed. In the present study, we aimed to study whether stimulation in the DLPFC can change participants’ revenge behavior in conditions where participants’ wealth was taken away in different ways. We adapted the moonlighting game and designed a new paradigm. Our study revealed that revenge behavior increased following activation in the right DLPFC, suggesting that the right DLPFC plays an important role in overriding self-interest and retaliation. In addition, our results revealed that the right DLPFC is crucial in revenge behavior related to the motivation of invasion. (shrink)

O presente artigo deriva de uma pesquisa qualitativa de cunho propositivo que busca levantar questões relacionadas à diferenciação e os atendimentos voltados para estudantes com Altas Habilidades ou Superdotação, à luz da educação matemática crítica. Para tal, é necessário compreender a definição, características, dificuldades e necessidades educacionais dos educandos com altas habilidades. Dentre estas necessidades estão o estímulo intelectual, o contato com pares, menos tempo em espera e desafios à altura de seu nível cognitivo, fatores que implicam na premência da (...) provisão de atendimento. A educação matemática tem grande impacto no resultado desse atendimento, pois participa da efetivação de ações de enriquecimento, aceleração e diferenciação que são direcionadas para os alunos superdotados. Nesse contexto, a partir dos conceitos de ‘empowerment’ e ‘disempowerment’ descritos por Skovsmose, discute-se o processo de diferenciação para compreender se ele implica no desempoderamento de certas comunidades, em especial de alunos não superdotados. Sendo a diferenciação um processo necessário para atender as necessidades dos educandos com Altas Habilidades, ela não pode ser rapidamente descartada como sendo discriminação por habilidades. Há, entretanto, atitudes e aspectos desse processo que são capazes de levar a formas de discriminação. Esta reflexão é necessária para compreender a interseccionalidade entre a educação de superdotados e a educação matemática crítica e fundamentar o trabalho dos educadores matemáticos, avançando a Educação Inclusiva e Especial.

Résumé: La technologie métallurgique de la Chine ancienne est connue pour son ancienneté et sa délicatesse, mais pendant longtemps, le peuple chinois a toujours été sensible aux idées philosophiques qu’elles contiennent et le manque de compréhension rationnelle et généralisation théorique. La technologie métallurgique est une technique typique de l’ancien artisanat chinois. Cet article présente une analyse détaillée des idées philosophiques contenues dans la technologie métallurgique, notamment la technologie de la fabrication du fer (sidérurgie) et la technologie de la fonte et (...) du moulage de bronze. Nous estimons que les principales caractéristiques de l’ancienne culture chinoise de la technologie métallurgique sont l’accent mis sur l’importance de la philosophie, l’accent mis sur “le temporel, les avantages géographiques, et l’harmonie humaine”, et l’accent mis sur la pensée philosophique sur l’“harmonie”.

There is controversy around whether presenting sub-character units such as radicals and strokes are beneficial to L2 Chinese learning. The present study explored the effects of radical markings and stroke order animations on learning Chinese characters. Forty Chinese L2 learners with native alphabetic languages were divided into high-and low-level groups. They were first required to learn Chinese characters under four conditions either: presented radical markings with stroke animations; presented no radical markings with stroke animations; presented radical markings without stroke animations; (...) or presented neither radical markings nor stroke animations. After learning, the participants were given character recognition and character-meaning matching tests. Results showed that the presentation of radical markings increased the participants’ reaction times in the character recognition test and decreased their recognition accuracy. Moreover, presenting stroke order animations also decreased the participants’ accuracy in recognizing characters. Beyond that, presenting radical markings and stroke order animations had no significant influence on character-meaning matching tests. These results indicate that providing radical and stroke information might interfere with character learning instead of facilitating character learning. The results suggest that excessive visual information introduced in the learning process may increase L2 learners’ cognition load. Also, the findings contribute to theoretical arguments about the analytic and holistic processing of Chinese characters and the pedagogical implications for teaching Chinese as a second language.

Extreme learning machine is a recent scheme for single hidden layer feed forward networks. It has attracted much interest in the machine intelligence and pattern recognition fields with numerous real-world applications. The ELM structure has several advantages, such as its adaptability to various problems with a rapid learning rate and low computational cost. However, it has shortcomings in the following aspects. First, it suffers from the irrelevant variables in the input data set. Second, choosing the optimal number of neurons in (...) the hidden layer is not well defined. In case the hidden nodes are greater than the training data, the ELM may encounter the singularity problem, and its solution may become unstable. To overcome these limitations, several methods have been proposed within the regularization framework. In this article, we considered a greedy method for sparse approximation of the output weight vector of the ELM network. More specifically, the orthogonal matching pursuit algorithm is embedded to the ELM. This new technique is named OMP-ELM. OMP-ELM has several advantages over regularized ELM methods, such as lower complexity and immunity to the singularity problem. Experimental works on nine commonly used regression problems indicate that the investigated OMP-ELM method confirms these advantages. Moreover, OMP-ELM is compared with the ELM method, the regularized ELM scheme, and artificial neural networks. (shrink)

In this paper, a three-dimensional chaotic system with a line equilibrium is studied, in which a single nonbifurcation parameter is used to control the amplitude and frequency. A variety of chaotic signals can be modified using the amplitude-frequency control switch. The realization of circuit simulation based on multisim further verifies the theoretical analysis. Finally, the method for encrypting color images is tested, and the process performance is valued. It shows that the novel chaotic oscillation has a promising application prospect in (...) image encryption. (shrink)

Naturalistic stimuli, including movie, music, and speech, have been increasingly applied in the research of neuroimaging. Relative to a resting-state or single-task state, naturalistic stimuli can evoke more intense brain activities and have been proved to possess higher test–retest reliability, suggesting greater potential to study adaptive human brain function. In the current research, naturalistic functional magnetic resonance imaging (N-fMRI) has been a powerful tool to record brain states under naturalistic stimuli, and many efforts have been devoted to study the high-level (...) semantic features from spatial or temporal representations via N-fMRI. However, integrating both spatial and temporal characteristics of brain activities for better interpreting the patterns under naturalistic stimuli is still underexplored. In this work, a novel hybrid learning framework that comprehensively investigates both the spatial (via Predictive Model) and the temporal [via convolutional neural network (CNN) model] characteristics of the brain is proposed. Specifically, to focus on certain relevant regions from the whole brain, regions of significance (ROS), which contain common spatial activation characteristics across individuals, are selected via the Predictive Model. Further, voxels of significance (VOS), whose signals contain significant temporal characteristics under naturalistic stimuli, are interpreted via one-dimensional CNN (1D-CNN) model. In this article, our proposed framework is applied onto the N-fMRI data during naturalistic classical/pop/speech audios stimuli. The promising performance is achieved via the Predictive Model to differentiate the different audio categories. Especially for distinguishing the classic and speech audios, the accuracy of classification is up to 92%. Moreover, spatial ROS and VOS are effectively obtained. Besides, temporal characteristics of the high-level semantic features are investigated on the frequency domain via convolution kernels of 1D-CNN model, and we effectively bridge the “semantic gap” between high-level semantic features of N-fMRI and low-level acoustic features of naturalistic audios in the frequency domain. Our results provide novel insights on characterizing spatiotemporal patterns of brain activities via N-fMRI and effectively explore the high-level semantic features under naturalistic stimuli, which will further benefit the understanding of the brain working mechanism and the advance of naturalistic stimuli clinical application.

Authoritarian leadership is of great significance to eastern countries, including China. Meanwhile, unethical employee behavior also exists in all types of social organizations. The relationship between authoritarian leadership and unethical employee behavior is worth studying. Senior leaders often do not have a direct influence on employees except for through their immediate supervisors. The leadership style of senior leaders also influences the leadership style of their subordinates. This paper studies how authoritarian manager leadership trickles down to unethical employee behavior through authoritarian (...) supervisor leadership and discusses the moderating effect of leader member exchange and an ethical climate. Through a questionnaire survey of 406 pairs of leaders, supervisors, and employees, the research results of the multilevel model show that authoritarian supervisor leadership is positively related to unethical employee behavior, authoritarian supervisor leadership mediates the relationship between authoritarian manager leadership and unethical employee behavior, LMX positively moderates the relationship between authoritarian manager leadership and authoritarian supervisor leadership and moderates the mediating effect of authoritarian supervisor leadership, and, that an ethical climate negatively moderates the relationship between authoritarian supervisor leadership and unethical employee behavior and moderates the mediating effect of authoritarian supervisor leadership.

If we do not shrink from making rough generalizations and adopt a broad, conventional approach, then what we call modernity refers to the process whereby a state of heterogeneity progresses toward homogeneity in time, space, human collectives, social order, and other areas. In his book The Cheese and the Worms, Carlo Ginzburg discusses a late-16th century incident of heterodoxy that cannot be classified into previously existing standard categories. As new knowledge was disseminated thanks to the invention of the Gutenberg printing (...) press, old and new knowledge came into conflict in the mind of a heterodox figure by the name of Menocchio. He attacked the church, saying that it was more important to love one’s neighbor than to love God. Through these small, humble manifestations of change, Ginzburg was able to reveal the juncture when European modern knowledge first emerged from a muddled, undifferentiated state into one of clarity, whereby over the course of about a century of fermentation, its contours eventually became clearly evident around the year 1800. This process has been termed by the pioneer of conceptual history Otto Brunner as the “threshold era”, and by Reinhart Koselleck as the beginning of the “saddle era”. (shrink)
