The H ∞ performance of a class of T-S fuzzy systems with Markovian-jump parameters is analyzed. A state feedback controller is designed for T-S fuzzy systems with Markovian-jump parameters. First, a new modal-dependent Lyapunov function composed of closed-loop functions is constructed, which can fully use system status information. Based on this function, the stability conditions with less conservatism are given by linear matrix inequalities. At the same time, a design algorithm for a state feedback controller is proposed for the Markovian-jump-parameters (...) T-S fuzzy systems, which ensures the system’s stability under the condition of H ∞ − γ performance. Simulation results demonstrate that the mentioned method is accurate and practical. (shrink)

BackgroundFamily consent is a prerequisite for the organ donation of the deceased in China. However, a large number of donors are individuals who died due to accidental injuries or unanticipated diseases, which means that most of the families of such donors have just experienced the sudden death of their loved one and have to make a donation decision in a short time. This decision may cause psychological stress and some psychological damage to the minds of relatives of the donors. In (...) addition, cultural sensitivity also has largely caused the relatives of donors inner conflicts and contradictions. And sometimes organ donation may still be stigmatized. However, have they received any emotional support and what is their emotional support needs are some questions that need to be answered. Therefore, this study aims to investigate the emotional support, influencing factors, and needs of the family members of organ donors in Hunan Province, China.Materials and methodsThis is mixed-methods research that combines quantitative and qualitative research methods. A cross-sectional survey was conducted among 102 donor families using a questionnaire to investigate their emotional support status. To further understand their emotional support needs, 12 donor families participated in the semi-structured interview.ResultsThe results confirmed that: A total of 67.7% of the 102 respondents received emotional support or psychological comfort. Thus, only a small number of respondents felt respected by the public. Emotional support came mainly from immediate family members, and official organizations such as the Red Cross. Marital status, health status, occupation, and coping style can affect the emotional support of the donor families. Interview showed that the families of donors need emotional support and psychological aid from psychological professionals mostly. And they also wish to receive the understanding and respect of the public.ConclusionMost families of organ donors received emotional support from family, Red Cross, and friends, but only a minority of families of donors reported receiving respect from the public after the donation. And families of donor showed a strong need for emotional support and professional psychological aid from institutions. (shrink)

Fourteen subjects were tape‐recorded while they undertook to find a law to summarize numerical data they were given. The source of the data was not identified, nor were the variables labeled semantically. Unknown to the subjects, the data were measurements of the distances of the planets from the sun and the periods of their revolutions about it—equivalent to the data used by Johannes Kepler to discover his third law of planetary motion.Four of the 14 subjects discovered the same law as (...) Kepler did (the period varies as the 3/2 power of the distance), and a fifth came very close to the answer. The subiects' protocols provide a detailed picture of the problem‐solving searches they engaged in, which were mainly, but not exclusively, in the space of possible functions for fitting the data, and provide explanations as to why some succeeded and the others failed.The search heuristics used by the subjects are similar to those embodied in the BACON program, computer simulation of certain scientific discovery processes. The experiment demonstrates the feasibility of examining some of the processes of scientific discovery by recreating, in the laboratory, discovery situations of substantial historical relevance. It demonstrates also, that under conditions rather similar to those of the original discoverer, a law can be rediscovered by persons of ordinary intelligence (i.e., the intelligence needed for academic success in a good university). The data for the successful subjects reveal no “creative” processes in this kind of a discovery situation different from those that are regularly observed in all kinds of problem‐solving settings.

Contextualism and Disagreement This paper argues that attributor contextualism is in conflict with ordinary language methodology. Attributor contextualism has at its center the thesis that, the truth-values of knowledge attributions vary with the conversational contexts. This thesis entails that if two speakers in similar contexts make conflicting knowledge attributions, at least one of these attributions is false. One important argument for attributor contextualism depends on ordinary language methodology, a methodology that places great trust in ordinary speakers and prevents judging a (...) substantial group of ordinary speakers' simple knowledge attributions false. I argue that there is strong empirical evidence that ordinary speakers do extensively disagree in similar contexts. My conclusion is that one cannot coherently hold the attributor contextualist thesis and use ordinary language methodology, because the lesson we learn from the empirical evidence is that using the methodology would prove the thesis false. Since prominent attributor contextualists explicitly adopt the methodology, and that the methodology is what distinguishes attributor contextualism from its main rival, invariantism, the conflict with the methodology is a problem for attributor contextualism.

Because of difficulty processing the electronic medical record data of patients with cerebrovascular disease, there is little mature recognition technology capable of identifying the named entity of cerebrovascular disease. Excellent research results have been achieved in the field of named entity recognition, but there are several problems in the pre processing of Chinese named entities that have multiple meanings, of which neglecting the combination of contextual information is one. Therefore, to extract five categories of key entity information for diseases, symptoms, (...) body parts, medical examinations, and treatment in electronic medical records, this paper proposes the use of a BERT-BiGRU-CRF named entity recognition method, which is applied to the field of cerebrovascular diseases. The BERT layer first converts the electronic medical record text into a low-dimensional vector, then uses this vector as the input to the BiGRU layer to capture contextual features, and finally uses conditional random fields to capture the dependency between adjacent tags. The experimental results show that the F1 score of the model reaches 90.38%. (shrink)

Drawing on the transactional model of stress, we propose that organizational identification and positive affectivity moderate the relationship between abusive supervision and proactive behavior. In Study 1, we collected data from a sample of 165 dentists and 41 supervisors in two Chinese hospitals. In Study 2, we used a sample of 226 employee-supervisor dyads from a large Chinese transportation company. The results of two studies showed that the interaction between abusive supervision and organizational identification on proactive behavior occurred only when (...) positive affectivity was high. We discuss theoretical and managerial implications and indicate future research directions. (shrink)

Statistics show, that even though an ethical respect for nature is both widely advocated by current mainstream environmental philosophy and is increasingly publicly accepted, this is not enough to ensure the needed practical actions to protect and preserve the natural world and its living beings. This reflects a disconnection between the related intellectual or theoretical appreciation of the integrity or value within the natural world and the sorts of practices needed to heal or to motivate the actions needed for ecological (...) integrity and sustainability. Awareness of this disunity or disconnection calls for a philosophical examination of this disconnection. This paper argues that the disunity between knowledge and practice reflects a “blind spot” in those sorts of mainstream environmental philosophy that attempt to establish a rational basis for an ethical respect for nature and humans’ ethical responsibility to the environment. This paper shall reveal that blind spot and its origin by examining and building on Ed Casey’s analysis and phenomenological description of an original and authentic directly lived ethical response to the environment that he calls the “first moment of ethical response.” Casey’s description of this “first moment of ethical response,” rooted in his phenomenological horizon, allows him to break away from the horizon of current mainstream environmental ethics and uncover a field of original and authentic ethical experience that opens an area of investigation closed to current environmental ethics. In this way Casey’s work can reveal the limitations of the scientific horizon of mainstream environmental ethics and has great value in the overcoming of the blind spot and its ill effect. (shrink)

The computer distance teaching system teaches through the network, and there is no entrance threshold. Any student who is willing to study can log in to the network computer distance teaching system for study at any free time. Neural network has a strong self-learning ability and is an important part of artificial intelligence research. Based on this study, a neural network-embedded architecture based on shared memory and bus structure is proposed. By looking for an alternative method of exp function to (...) improve the speed of radial basis function algorithm, and then by analyzing the judgment conditions in the main loop during the algorithm process, these judgment conditions are modified conditionally to reduce the calculation scale, which can double the speed of the algorithm. Finally, this article verifies the function, performance, and interface of the computer distance education system. (shrink)

The current piano curriculum, according to conventional wisdom, is a product of the western music education system, which accords Chinese traditional culture with less importance. Most of the methods and tools used in today's collegiate piano programs are Western-based, often ignoring traditional musical traditions. However, it is widely acknowledged that piano music plays a key role in the culture of music and that it is closely related to traditional culture and art. Examining the impact of Chinese traditional philosophy on collegiate (...) piano instruction and performance is the main objective of the present research. The study makes use of an empirical method by conducting a survey and gathering information using a questionnaire. 174 students from six Chinese institutions participated in the current research. Students were split into two groups as a result of the training methodology. 87 students in the experimental group studied using a previously developed curriculum to advance Chinese traditional music culture, whereas 87 students in the control group took piano lessons using the standard curriculum. We used the student’s t-test and Chi-square test for statistical analysis. Since it demonstrates how traditional Chinese philosophy is successfully promoted in educational contexts, the present study is significant from both an academic and a practical standpoint. (shrink)

Various studies have recognized the importance of humility as a foundational aspect of virtuous leadership and have revealed the beneficial effects of leader humility on employee moral attitudes and behaviors. However, these findings may overestimate the benefits of leader humility and overlook its potential costs. Integrating person–supervisor fit theory and balance theory with the humility literature, we employ a dyadic approach to consider supervisor and employee humility simultaneously. We investigate whether and how the congruence of supervisor and employee humility influences (...) employee citizenship and deviance behaviors. We conducted a multilevel, multiphase, and multisource field study to test our hypotheses. The results of cross-level polynomial regression analyses revealed that when supervisors and employees were incongruent in humility, employees experienced higher levels of negative affect toward supervisors. Also, compared to those in low–low congruent dyads, employee negative affect toward supervisors was lower in high–high congruent dyads. The results further revealed asymmetric incongruence effects: employees experienced the highest levels of negative affect toward supervisors when their own humility was lower than their supervisors’. In addition, we found that employee negative affect toward supervisors mediated the impacts of supervisor–employee congruence in humility on employee organizational citizenship behavior and counterproductive work behavior.

One of the crucial fields of study that is getting more attention is association rule mining. It is crucial to databases' knowledge discovery (KDD). KDD and association rule mining have a very broad use. It has evolved at a rapid rate over the past fifteen years. Association Rule Mining is a novel technology, although it is still in the discovery and development stages. Video is an illustration of interactive media data since it contains text, pictures, meta-data, visual, sound, and different (...) kinds of data. It is frequently used for a variety of important likely reasons, such as security and reconnaissance, amusement, healthcare, educational endeavours, and sports. One of the main issues for the local data-mining research community is video data mining, which aims to find and comprehend fascinating examples from the large volume of video data. Video data mining is still in its infancy when compared to mining other sorts of data. It is pivotal to grasp and naturally mine the information from video databases considering the continually extending computerized libraries and video databases. Differentiating association rules between components in a significant video library is critical in the field of video data mining. As per continuous imaginative work, association rule mining is being utilized rapidly in various tasks, including perception, social affairs, broadcast news, sports, records, films, clinical data, as well as on the web and individual media assortments. This exploration tries to give a far-reaching method to association rule extraction from video databases. (shrink)

Empirical studies have suggested that language-capable robots have the persuasive power to shape the shared moral norms based on how they respond to human norm violations. This persuasive power presents cause for concern, but also the opportunity to persuade humans to cultivate their own moral development. We argue that a truly socially integrated and morally competent robot must be willing to communicate its objection to humans’ proposed violations of shared norms by using strategies such as blame-laden rebukes, even if doing (...) so may violate other standing norms, such as politeness. By drawing on Confucian ethics, we argue that a robot’s ability to employ blame-laden moral rebukes to respond to unethical human requests is crucial for cultivating a flourishing “moral ecology” of human–robot interaction. Such positive moral ecology allows human teammates to develop their own moral reflection skills and grow their own virtues. Furthermore, this ability can and should be considered as one criterion for assessing artificial moral agency. Finally, this paper discusses potential implications of the Confucian theories for designing socially integrated and morally competent robots. (shrink)

ABSTRACT Although unethical pro-organizational behavior (UPB) in the workplace has been widely researched, studies have focused on its antecedents rather than its outcomes. To fill this gap in the literature, we integrated moral licensing theory and the literature on leader gratitude expression to explore the ethical consequences of UPB. Using a sample of multi-source time-lagged surveys of 206 leader–employee dyads, we found that the pro-organizational nature of UPB fostered employees’ psychological entitlement and thereby increased their likelihood of engaging in subsequent (...) unethical behavior. Leaders’ expressions of gratitude for employee UPB strengthened the relationship between UPB and psychological entitlement, ultimately reinforcing employees’ unethical behavior. The theoretical and practical implications of the findings are discussed. (shrink)

Some engineering educators recognize the necessity and challenges of teaching students moral sensitivity. As recently pointed out by some scholars, along with moral sensitivity, promoting “self-knowledge” is significantly lacking in engineering curricula. We suggest that the “ethics autobiography” employed in some health and psychological science programs can serve as a useful tool for helping engineering students develop moral sensitivity and self-reflective competencies. First, this paper briefly discusses some unique potential strengths of introducing ethics autobiography as a tool for moral pedagogy (...) to engineering education. Second, this paper provides five specific examples on how to implement ethics autobiography in the classroom. Among the five examples, two are directly related to engineering education and the other three can easily be adapted to meet the needs of engineering education. Finally, this paper concludes with some discussion of the implications of ethics autobiography for engineering ethics education reform and the limitations and ethical considerations of using autobiography in moral pedagogy.

Engineering programs in the United States have been experimenting with diverse pedagogical approaches to educate future professional engineers. However, a crucial dimension of ethics education that focuses on the values, personal commitments, and meaning of engineers has been missing in many of these pedagogical approaches. We argue that a value-based approach to professional ethics education is critically needed in engineering education, because such an approach is indispensable for cultivating self-reflective and socially engaged engineers. This paper starts by briefly comparing two (...) prevalent approaches to ethics education in science and engineering: professional and philosophical. While we acknowledge that both approaches help meet certain ethics education objectives, we also argue that neither of these is sufficient to personally engage students in authentic moral learning. We make the case that it is important to connect ethics education to the heart, which is extensively driven by values, and present a value-based approach to professional ethics education. We provide some classroom practices that cultivate a safe, diverse, and engaging learning environment. Finally, we discuss the implications of a value-based approach to professional ethics education for curriculum design and pedagogical practice, including opportunities and challenges for engineering faculty eager to incorporate value-based inquiry into their classrooms.

Little is known about the Korean Peninsula before 12 th century, due to which potentially biased assessments of its social, cultural, and political history exist. This study attempted to unearth the history of the Korean Peninsula since the late 10th century through the Buddhist inscriptions. These inscriptions unveil the authentic social environment, religious beliefs, and political ecology of late Silla and delve into the political motives and life philosophies of Silla scholars who studied the Tang Dynasty, especially their approach of (...) 'interpreting Buddhism through Confucianism'. Based on empirical research grounded in documentary evidence, combined with literary-historical methods, this study examined the inscriptions of two great Silla scholars Choi Chi-Won and Choi Eun-Wee. Their works predominantly feature Confucian thought within Buddhist narratives. Politically, they used Confucian principles as the foundation for governance, interpreting them through Buddhist concepts to enlighten the masses and strengthen dynastic rule. Ideologically, while Choi Chi-Won fully implemented Confucian logic, Choi Eun-Wee demonstrated a stronger Buddhist inclination. This research enriches the understanding of the history, culture, and society of the Korean Peninsula, highlighting the significant role of blending Confucian and Buddhist elements in shaping its social and political structures.

There is little doubt that China's reform can be seen as a special case in the history of humanity, of modernization, and even in the relatively short history of economic transition. In terms of market-oriented choice, reform in China is not different from that in most countries in the world. With respect to the transition from a command to a market-based economy, comparable countries could be narrowed down to most of the former communist states that bear similarity. When taking into (...) consideration the circumstances in which the ongoing corporatization and/or privatization take place under the conditions of a regime that is nondemocratic in both polity and, to a large extent, resource allocation, however, the matching number of countries would be further reduced to a few, such as Vietnam and some autocratic small nations. Again, among these few, China's reform has its own specific features. (shrink)

In this paper, we mainly investigate the coordinated tracking control issues of multiple Euler–Lagrange systems considering constant communication delays and output constraints. Firstly, we devise a distributed observer to ensure that every agent can get the information of the virtual leader. In order to handle uncertain problems, the neural network technique is adopted to estimate the unknown dynamics. Then, we utilize an asymmetric barrier Lyapunov function in the control design to guarantee the output errors satisfy the time-varying output constraints. Two (...) distributed adaptive coordinated control schemes are proposed to guarantee that the followers can track the leader accurately. The first scheme makes the tracking errors between followers and leader be uniformly ultimately bounded, and the second scheme further improves the tracking accuracy. Finally, we utilize a group of manipulator networks simulation experiments to verify the validity of the proposed distributed control laws. (shrink)

Experimental results show that the proposed approach is feasible and effective. (shrink)

Der Aufsatz diskutiert die zentralen Gedanken Niklas Luhmanns über die Individualitätsbildung und Freiheitslage der Menschen in der segmentär, stratifikatorisch und funktional differenzierten Gesellschaft. Die Individualität und mithin die Freiheit der Menschen wird in den ersten beiden Differenzierungsformen durch Inklusion in Familien, Haushalten, Stämmen, Ständen etc. ermöglicht, also von außen bestimmt. In der modernen funktional differenzierten Gesellschaft muss man hingegen seine Individualität selbst bilden, weil man von den Funktionssystemen nur durch Anpassung an ihre Forderungen inkludiert werden kann, was heute vor allem (...) durch einen Karriereverlauf möglich ist. Als Individuum hat man aber auch die Freiheit, sich dem zu widersetzen und sich zurückzuziehen. Ferner zeichnet sich die moderne Gesellschaft dadurch aus, den Individuen die Freiheit einzuräumen, Ansprüche an sie zu stellen, damit sie ihre eigenen Strukturen dementsprechend aufbauen kann. Luhmanns Beschreibung der modernen Verhältnisse hat auch für die „Nachzügler“ der Modernisierung wie z.B. China Relevanz. (shrink)

Reading-to-write is an essential skill in academic writing, and reading-writing tasks have been widely adopted in standardized English tests. Much more recent literature on integrated reading-writing tasks has focused on writers’ use of source texts or the validity of integrated writing assessment, while little is known about whether the nature of the types of reading texts has any bearing on integrated reading-writing tasks. This study examines whether the types of reading texts have any influence on second language students’ argumentative writing (...) in terms of the use of argument elements and its overall quality. Fifty-four Chinese second-year university students majoring in English language teaching were asked to write an argumentative essay after reading texts with either similar views or opposing views. Results show that students reading texts with opposing viewpoints presented more data and higher overall quality of argumentative essays than students reading texts with similar viewpoints, although the latter group presented more counterargument data. Pedagogical implications on teaching argumentative writing are discussed. (shrink)

In this work, a virtual submerged floating operational system based on parallel and serial robotic platforms is proposed. The primary aim behind its development lies in carrying out simulated underwater manipulation experiments in an easier and safer way. This VSFOS is consisted of a six-degree-of-freedom parallel platform, an ABB serial manipulator, an inertial sensor, and a real-time industrial computer. The 6-DOF platform is used to simulate the movement of an underwater vehicle, whose attitude is measured by the inertial sensor. The (...) ABB manipulator, controlled by the real-time industrial computer, works as an operational tool to perform underwater manipulation tasks. In the control system architecture, software is developed to receive the data collected by the inertial sensor, to communicate and send instructions. Furthermore, the real-time status of the manipulator is displayed in this software. To validate the proposed system, two experiments have been conducted to test its performance. In the first experiment, the test is carried out to check the communication function of VSFOS, while in the second one, the manipulator is intended to follow the movement of the parallel platform and perform simulated operational task in the space. The obtained results from these two experiments show clearly the effectiveness and the performance of the proposed VSFOS. (shrink)

Developmental and neuroscience works have demonstrated that the moral judgment is influenced by theory of mind, which refers to the ability to represent the mental states of different agents. However, the neural and cognitive time course of interactions between moral judgment and ToM remains unclear. The present event-related potential study investigated the underlying neural substrate of the interaction between moral judgment and ToM by contrasting the ERPs elicited by moral judgments for self and for others in moral dilemmas. In classic (...) moral dilemmas, the agents must choose between the utilitarian choice and the non-utilitarian choice. The ERPs were recorded from participants who made moral judgments for self and for others when the agent made utilitarian or non-utilitarian choices during the dilemma. The results revealed that the moral judgment for others elicited a larger frontal late positive component than that for self when the agents made utilitarian choices, while no difference was observed on early components of N1, P2, and N2. Moreover, individual differences in mentalizing ability were negatively correlated with the LPC amplitudes. These findings suggested that ToM modulated the late controlled process but not the early automatic process during moral judgments. (shrink)

Spontaneous activity levels prior to stimulus presentation can determine how that stimulus will be perceived. It has also been proposed that such spontaneous activity, particularly in the default-mode network (DMN), is involved in self-related processing. We therefore hypothesised that pre-stimulus activity levels in the DMN predict whether a stimulus is judged as self-related or not. Method: Participants were presented in the MRI scanner with a white noise stimulus that they were instructed contained their name or another. They then had to (...) respond with which name they thought they heard. Regions where there was an activity level difference between self and other response trials two seconds prior to the stimulus being presented were identified. Results: Pre-stimulus activity levels were higher in the right temporoparietal junction (RTPJ), the right temporal pole (RTP), and the left superior temporal gyrus in trials where the participant responded that they heard their own name than trials where they responded that they heard another. Conclusion: Pre-stimulus spontaneous activity levels in particular brain regions, largely overlapping with the DMN, predict the subsequent judgement of stimuli as self-related. This extends our current knowledge of self-related processing and its apparent relationship with intrinsic brain activity in what can be termed a rest-self overlap. (shrink)

This paper will first introduce the development of professional ethics of counseling and psychotherapy in mainland China. Ethical awareness is often limited due to variations in training experiences. Aligning with ethics codes can also bring challenges due to nuances within Chinese culture.

These ethical issues are often discussed within an individualistic cultural frame and presentation from a collectivist (...) culture offers a unique perspective in the ethics literature. (shrink)

In traditional Chinese political philosophy, there has been a lack of explicit discussion on the power-responsibility relationship or the contract state . Western learning does not lack such content. As Western countries have already resolved the question of power-responsibility correspondence by means of constitutional democracy, it has become a linguistic usage of theirs that is not all too logical but quite harmless in practice to discuss “big and small” questions without taking power and responsibility into account. Yet, were our countrymen, (...) our compatriots, who are first of all muddleheaded about the relationship between power and responsibility, to take over and accept such language as theirs and discuss “their problems,” there would be great harm. If it is a mere academic error to say “State power does not go down to the county level,” which in history is actually “The state is not responsible for anybody and anything below the county level,” then the following will bring real harm.

Total factor productivity is not only the core of high-quality economic development but also a core indicator for measuring the quality of economic development. Improving total factor productivity is one of the most critical points in building a modern economic system. Firstly, this paper uses the DEA-Malmquist index method to measure and decompose the total factor productivity of China’s 30 provinces, municipalities, and autonomous regions from 2001 to 2017 and analyzes the characteristics of its temporal and spatial changes. From a (...) spatial perspective, the regional gap is relatively large. Secondly, we construct the index system of five dimensions and use this index system to comprehensively evaluate the improvement degree of China’s modernized economic system. The results show that the overall level of the improvement degree of China’s modernized economic system is relatively low, and the differences between provinces are great. Thirdly, this paper uses static and dynamic spatial econometric models to empirically analyze the effect of total factor productivity on the improvement degree of the modern economic system. The results show that the improvement degree of the modern economic system in China has obvious characteristics of time spillover and space spillover. Finally, we put forward countermeasures and suggestions on how to perfect the modern economic system. (shrink)

Studies have shown that performance‐dependent monetary rewards facilitate visual perception. However, no study has examined whether such a positive effect is limited to the rewarded task or may be generalized to other tasks. In the current study, two groups of people were asked to perform two visual perception tasks, one being a reward‐relevant task and the other being a reward‐irrelevant task. For the reward‐relevant task, the experimental group received performance‐dependent monetary rewards, whereas the control group did not. For the reward‐irrelevant (...) task, both groups were not rewarded. The two tasks were randomly intermixed trial by trial (Experiment 1) or presented block by block (Experiment 2) or session by session (Experiments 3a, 3b, and 3c). Results showed that performance‐dependent monetary rewards improved participants' performance on the relevant task in all experiments and impaired their performance on the irrelevant task in Experiments 2, 3a, 3b, and 3c. These results suggested that monetary rewards might incur a cost on reward‐irrelevant tasks. Finally, the benefit of monetary rewards disappeared when they were no longer provided during the final session. This is the first study that reveals both the bright and dark sides of the performance‐dependent monetary rewards in visual perception. (shrink)
