This paper aims at investigating the dynamic characteristics of a microring driven by dual arch electrodes because they are basic elements of microelectrostatic motors. The dual arch electrodes surround the periphery of the microring and are arranged symmetrically to the center of the ring. The electrodes are fixed while the microring is flexible. The electrostatic force will deform the microring, while the deflection of the microring changes the gap between the microring and the electrodes, thereby changing the electrostatic force. Therefore, (...) this is an electromechanical coupling effect. The nonlinear partial-differential equation that governs the motion of the microring is derived based on thin shell theory. Then, based on the assumption of small deflection, the nonlinear governing equation is linearized by truncating the higher-order terms of the Taylor series expansion of the nonlinear electrostatic force. After that, the linearized governing equation is discretized into a set of ordinary differential equations using Galerkin method in which the mode shape functions of the ring are adopted. The influences of the structural damping of the microring and the span of the arch electrodes on the forced response and dynamical stabilities of the microring are investigated. The results show that the damping ratio has a great influence on the system instability during high-frequency excitation. The unstable region of the system can increase with the increase of the electrode span; the response amplitude can also be increased within a certain range. (shrink)

Hydromechanical continuously variable transmission is capable of bearing large torque and has wide transmission range, which is suitable for high-power tractors. Dynamic characteristics could influence the tractor life, especially in a high-power tractor. Wet clutch is the crucial component in the HMCVT, which could smooth and soft power transmission. Therefore, it is important to study the dynamic characteristics and implement the wet clutch test of HMCVT. In this paper, AMESim is used to establish virtual models of gearbox, pump-controlled hydraulic motor (...) system, and shifting hydraulic system. Then, a simulation study of tractor operation under working condition is carried out. The internal and external meshing forces of the planetary row are analyzed. Finally, the wet clutch engagement process of HMCVT in the high-power tractor is tested to verify the oil pressure. The simulation results show that the values of internal and external meshing force become larger as the throttle opening increases. At the moment of shifting change, the meshing forces of the planetary gear have great impact. The clutch test shows that the trend of the oil filling curve obtained from the bench test is similar to that obtained from the theoretical curve, which verifies the simulation results. (shrink)

Does the level of marketing activity in a country contribute to societal well-being or quality of life? Does economic efficiency also play a positive role in societal well-being? Does economic efficiency also moderate or mediate the marketing activity effect on societal well-being? Marketing activity refers to the pervasiveness of promotion expenditures and number of retail outlets per capita in a country. Economic efficiency refers to the extent to which the economy is unhampered by corruption, burdensome government regulation, and a large (...) informal economy. We used secondary data from the World Bank and other statistical sources to answer these questions. Our study findings suggest that both marketing activity and economic efficiency contribute positively to societal well-being, and that economic efficiency plays more of a mediator than moderator role between marketing activity and societal well-being. The public policy implication of this study is that increases in marketing activity and economic efficiency in countries characterized as low on both dimensions should significantly increase the quality of life in those countries.

一部從玄學美學角度對中國審美範式進行深入系統研究的文藝美學專著。為了有別于以西方美學為主要參照系的審美形態論，作者在書中提出了“審美範式”。 概念，這是作者的獨創。作者將中國審美範式分為“中和”“氣韻”“意象”和“意境”四種，並分析了這四種審美範式的精神特質、內在理路、表現特征以及美學價值，以求建構中國審美範式的理論框架。.

Some previous studies have explored the impact of family function on school belonging. However, little is known about the parallel mediating relationship underlying them. This study aims to investigate the formation mechanism of school beginning in a sample of Chinese adolescents and examined the parallel mediating role of interpersonal self-support and individual self-support in the link between family function and school belonging. A cross-sectional study was conducted in four schools of the district of Hunan province in China, and 741 students (...) were surveyed using cluster sampling. Family cohesion and adaptability scale (FACES), Adolescent students self-supporting personality scale (SSPS-AS), School belonging scale were applied. The results indicated that interpersonal self-support and individual self-support, together, and uniquely, parallel mediated the relationship between family function and school belonging. It can be concluded that family function not only has direct effects on school belonging but also has indirect effects through interpersonal self-support and individual self-support. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:A Leaky Boat Holding Wine: A Study of the Word-Meaning Debate in Wei-Jin Six Dynasties Period Thought by Jing YuanRun Gu (bio)Lou Chuan Zai Jiu: Yanyi zhi Bian yu Wei-Jin Liu Chao Sixiang Xueshu Yangjiu 漏船载酒: 言意之辨与魏晋六朝思想学术研究 (A Leaky Boat Holding Wine: A Study of the Word-Meaning Debate in Wei-Jin Six Dynasties Period Thought). By Jing Yuan 袁晶. Shanghai: Shanghai People's Press, 2022. Pp. 247. Paperback RMB23.93, isbn (...) 978-7-208-17567-9.In A Leaky Boat Holding Wine: A Study of the Word-Meaning Debate in Wei-Jin Six Dynasties Period Thought (hereafter A Leaky Boat Holding Wine), Jing Yuan offers a careful review and critical evaluation of one of the major philosophical topics in the Wei-Jin period, namely, the word-meaning (Yanyi 言意) debate. In several previous publications, Yuan has addressed the word-meaning controversy from different angles and in various classics, including Prajnaparamita and The Analects.The word-meaning debate, as Yuan explains, can be interpreted as a conflict between cognition and expression, and reveals a series of contradictions and conflicts in ontology, epistemology, and philosophy of life among scholars in the Wei-Jin period. The debate refers to the controversy on whether words can fully express meaning or not. It departs from the relationships between word and meaning to critically evaluate their functions and limitations, and mainly consists of two ways of thinking: "distinguishing names, analyzing principles" (bian ming xi li 辯名析理) and "getting the meaning, forgetting the words" (de yi wang yan 得意忘言). Although this debate had already developed in China for quite some time, it was only prevalent as a common philosophical theme in the Wei-Jin period, a time characterized by social disorder and endless war. The metaphor in the book title, "a leaky boat holding wine," is from one of Lu Xun's (1881) poems, illustrating that although people use words as a tool to express meaning, it is impossible for words to convey all meaning. Yuan uses the metaphor to refer to the capacity of a word to carry meaning, and indicates that human thought and expression are inseparable from words, but cannot be entirely restricted to them.The book is organized in chronological order, and readers can easily grasp how the word-meaning debate was developed and reshaped in different periods, responding to various social-political contexts. Chapter 1 starts with the origin of the debate in the early Qin period. The author provides a solid examination of relevant theories and high-quality secondary literature. She clearly demonstrates that both early Daoist and Confucian thinkers were involved in the debate, and [End Page 1] that it aimed to describe a core ontology--or a search for the principles of the cosmos--and understand various other aspects of the world, including natural cycles and social ethics. Confucius advocated a metaphorical grasp of the Dao, transforming epistemology into practical philosophy. He held a critical attitude toward the relationship of word and meaning, arguing that words could express meaning because people could use them to influence the state and society. Confucius also believed that Dao, as an imaginative and contextual concept, could not be expressed through words.In contrast, Zhuangzi--"the most significant source of inspiration for Neo-Daoism (Metaphysics) in the Wei-Jin period" (p. 70)--focuses on the limitations of the function of words to convey meaning, highlighting the ineffable nature of Dao. Zhuangzi's concept of Dao, according to Yuan, is always beyond the reach of our senses and can only be attained through an intuitive grasp of reality: through the ability to reach an epiphany and perceive through the mind, even when not observing through physical means. It is only with an intuitive way of thinking that one can identify the ultimate noumenon and grasp the idea of Dao when words cannot contain it. In Zhuangzi's epistemology, Dao is grasped using a method of knowing that transcends ordinary sense perception, knowledge or rationality, and provides a non-logical intuition and an experience of a practical nature that transcends knowing.On this basis, the author brings together ancient and current research on the word-meaning debate, to critically assess the impact of Zhuangzi...
