This paper addresses variable-time impulsive control for coordinated tracking problem in nonlinear multiagent systems. To make followers coordinately track the leader, a variable-time impulsive controller is designed. Under some well-selected conditions, the comparison system of variable-time impulsive tracking control system is constructed by employing B-equivalence method. And we theoretically demonstrate that the two systems have the same stability property. Coordinated tracking criteria of multiagent systems are obtained by considering the comparison system. Numerical simulation is also provided to illustrate the correctness (...) of theoretical results and the efficiency of the variable-time impulsive controller. (shrink)

PurposeGross motor skills and inhibitory control which are both development in preschool stage is significant for preschooler to healthy growth. However, the evidence of relationship between them in preschoolers are still insufficient, most of studies only focus on youth. Thus, the aim of this research is to examine the association between GMS and IC in preschool children.MethodsThis cross-sectional study used baseline data from a previous intervention study of preschoolers conducted in 2018. GMS were assessed by using the Test for Gross (...) Motor Development in preschoolers, which includes two subtests of locomotor and object control skills. Total GMS is calculated from the sum of these two subtests. The Fish Flanker task was used to evaluate both accuracy and reaction time of IC. Multivariate linear regression models were established to analyze the relationships between GMS and IC.ResultsA total of 123 preschool-age children were included in the final analysis. After adjusting for confounders, GMS, locomotor, and object control skills were all negatively related with reaction time of IC.ConclusionThere was a significant negative correlation between gross motor skills and the reaction time of inhibitory control in preschool children. Further research is needed to verify this finding in prospective and experimental studies. (shrink)

The Chinese have a 5000 years history and with it goes its Chinese philosophy. However, Chinese philosophy differs from western philosophy in more than one way. Western philosophy's famous “why” questions and free thinking were not part of Chinese philosophy. Acceptance was the rule and Confucius is known to be the source for this philosophy. The 20th century brought changes both in thinking generally as well as how sports were perceived. The main reasons for this were the opening to the (...) west and improving economic situations for the general population. This led to research in the field of sport philosophy on academic levels both in Taiwan and China. This article tries to put the achievements in this field in on the map. (shrink)

Rawls's recent articulation of his theory of justice in Political Liberalism (1993) carries on the contractarian approach to defining justice, which was first laid out in A Theory of Justice (1971). However, this approach is now characterised as ‘political’, not metaphysical. It is intended to appeal to those who are deeply divided by cultural, religious, and moral beliefs: it is to explain how justice can be stable in a divided society. This ‘political’approach, nevertheless, has narrowed its appeal. Since it relies (...) on the shared ideas in democratic societies, its appeal becomes political and cultural. Morever, this theory's requirement of equal basic liberties for a just society calls for a relatively developed economy and social institutions. It fails to provide guidance to societies that, owing to their lesser development, cannot afford to guarantee the worth of equal basic liberties. The structual insufficiency of Rawls's ‘political’theory explains the failure of his continuing efforts to extend his liberal theory of justice to the international terrain. This essay analyses this insufficiency and the narrow applicability of Rawls's ‘political’theory of justice. (shrink)

Study on conduct of life of Muslim women and women in Islamic perspective.

This study investigates the association between work-family conflict and organizational citizenship behavior and examines the mediated role of subjective happiness between and the moderated part of family support. A moderated mediation model is established based on the Conservation of Resources theory. We collected data from 386 employees of nine companies in China. This study shows that the work-family conflict of female professional employees is negatively correlated with organizational citizenship behavior, and that the relationship is mediated by subjective well-being. Furthermore, female (...) professional employees’ family support moderates the effects of work-family conflict on subjective happiness and organizational citizenship behavior, with the relationship weaker when family support is higher. This study enriches the literature on work-family conflict by using family support as a mediating mechanism for work-family conflict. It enhanced our understanding of the influencing mechanisms of organizational citizenship behavior by constructing a more detailed model. (shrink)

Contrary to the assumption of arbitrariness in modern linguistics, sound symbolism, which is the non-arbitrary relationship between sounds and meanings, exists. Sound symbolism, including the “Bouba–Kiki” effect, implies the universality of such relationships; individuals from different cultural and linguistic backgrounds can similarly relate sound-symbolic words to referents, although the extent of these similarities remains to be fully understood. Here, we examined if subjects from different countries could similarly infer the surface texture properties from words that sound-symbolically represent hardness in Japanese. (...) We prepared Japanese sound-symbolic words of which novelty was manipulated by a genetic algorithm. Japanese speakers in Japan and English speakers in both Singapore and the United States rated these words based on surface texture properties, as well as familiarity. The results show that hardness-related words were rated as harder and rougher than softness-related words, regardless of novelty and countries. Multivariate analyses of the ratings classified the hardness-related words along the hardness-softness dimension at over 80% accuracy, regardless of country. Multiple regression analyses revealed that the number of speech sounds /g/ and /k/ predicted the ratings of the surface texture properties in non-Japanese countries, suggesting a systematic relationship between phonetic features of a word and perceptual quality represented by the word across culturally and linguistically diverse samples.

In late autumn of the year 1995, trudging alone over ice- and snow-covered hills and plains, I walked into the Crow Valley in mountainous western Colorado and examined the sites of ancient American Indian tribes. Local archaeologists had told me the Indians living here had migrated from North China and Northeast China nine thousand years ago. I returned from the mountains that evening and made my way to a wooden cabin for archaeologists, built in a col. I planned to have (...) supper there. To my surprise the little dining room, which normally was occupied only by myself and two undergraduate archaeologists, was packed with youngsters. (shrink)

Uncertainty natural language processing has always been a research focus in the artificial intelligence field. In this paper, we continue to study the linguistic truth-valued concept lattice and apply it to the disease intelligent diagnosis by building an intelligent model to directly handle natural language. The theoretical bases of this model are the classical concept lattice and the lattice implication algebra with natural language. The model includes the case library formed by patients, attributes matching, and the matching degree calculation about (...) the new patient. According to the characteristics of the patients, the disease attributes are firstly divided into intrinsic invariant attributes and extrinsic variable attributes. The calculation algorithm of the linguistic truth-valued formal concepts and the constructing algorithm of the linguistic truth-valued concept lattice based on the extrinsic attributes are proposed. And the disease bases of the different treatments for different patients with the same disease are established. Secondly, the matching algorithms of intrinsic attributes and extrinsic attributes are given, and all the linguistic truth-valued formal concepts that match the new patient’s extrinsic attributes are found. Lastly, by comparing the similarity between the new patients and the matching formal concepts, we calculate the best treatment options to realize the intelligent diagnosis of the disease. (shrink)

The Japanese are fond of making an analogy between human life and the cherry blossom, which flowers very briefly and then withers. Xiaobo's life was like the cherry blossom: He, too, flowered for a brief moment and then abruptly passed away.

Choice revision is a sort of non-prioritized multiple revision, in which the agent partially accepts the new information represented by a set of sentences. We investigate the construction of choice revision based on a new approach to belief change called descriptor revision. We prove that each of two variants of choice revision based on such construction is axiomatically characterized with a set of plausible postulates, assuming that the object language is finite. Furthermore, we introduce an alternative modelling for choice revision, (...) which is based on a type of relation on sets of sentences, named multiple believability relation. We show without assuming a finite language that choice revision constructed from such relations is axiomatically characterized with the same sets of postulates that we proposed for the choice revision based on descriptor revision, whenever the relations satisfy certain rationality conditions.

“Rough set” is a theory put forward by the polish scholar Z. Pawlak, which is a useful mathematics tool for dealing with vague and uncertain information. Rough set theory can achieve a subset of all attribute which preserves the discernible ability of original features, by using the data only with no additional information. As a typical system of multi-agent, the decision-making system of soccer robot has the features of multi-layered, antagonism, and cooperation. On the bases of rough set theory, this (...) paper established a decision making system with complete information for soccer robot, and then reduce the condition and decision attributes and their values, to get the simply decision rules. On the otherwise, considering the situation of information loss, we study decision making of imperfect information system, extract the decision rules and calculate the reliability, so that the rules can assist the agent to make right decision in competition. The simulation result shows that the algorithm is correct and effective. (shrink)

The rapid development of modern science and technology, especially the widespread use of the Internet has, to a large extent, transformed the way culture comes into being and is disseminated. The Internet has greatly increased the coverage of information on political thought as well as cultural information; it has also provided advanced measures and a vast arena for political thought work. At the same time, it has created many new situations and problems for political thought work in the new era. (...) Only if we fully acknowledge these changes will we be capable of seizing these opportunities, meeting the challenges, and achieving good results in political thought work in this new era. (shrink)
