Aiming at the oscillation suppression of spacecraft with large flexible appendages, we propose a control strategy using H∞ control. The weighting functions are designed for the specific flexible modes of the spacecraft and the frequency of harmonic interference in its operating environment. Taking into account the structural uncertainty of systematic modeling and the comprehensive performance requirements of system bandwidth constraint and attitude stability, the H∞ comprehensive performance matrix is constructed. A space telescope with a large flexible solar array is presented (...) as an illustrative example, and a control design that meets the requirement for pointing accuracy is proposed. The simulation results show that the designed controller satisfies the requirements of attitude stability and high pointing accuracy and has effectively suppressed the disturbance of endemic frequency. The design scheme and selection method of the weight function shown in this paper can be a reference for the controller design for oscillation suppression of this type of spacecraft with flexible structures.

This article reports a survey of nurses in different cultural settings to reveal their perceptions of ethical role responsibilities relevant to nursing practice. Drawing on the Confucian theory of ethics, the first section attempts to understand nursing ethics in the context of multiple role relationships. The second section reports the administration of the Role Responsibilities Questionnaire (RRQ) to a sample of nurses in China (n = 413), the USA (n = 163), and Japan (n = 667). Multidimensional preference analysis revealed (...) the patterns of rankings given by the nurses to the statements they considered as important ethical responsibilities. The Chinese nurses were more virtue based in their perception of ethical responsibilities, the American nurses were more principle based, and the Japanese nurses were more care based. The findings indicate that the RRQ is a sensitive instrument for outlining the embedded sociocultural factors that influence nurses’ perceptions of ethical responsibilities in the realities of nursing practice. This study could be important in the fostering of partnerships in international nursing ethics. (shrink)

This article examines the rise and decline of the enthusiasm for intelligence testing in early twentieth-century China, focusing on the appeal, the challenges, and the critiques revolving around this psychological instrument. The introduction of intelligence testing reflected not only China’s urgent needs in modernizing its merit system, but also Chinese psychologists’ aspirations for pursuing exactitude and redefining the racial characteristics of their compatriots against foreign interpretations. But despite psychologists’ endeavors, the political and geographical fragmentation of Republican China troubled the epistemic (...) imperative of uniformity demanded by Euro-American psychometrics and therefore undermined the validity of measurement. Subsequently, the legitimacy of intelligence testing began to be questioned by several influential Chinese psychologists in the late 1920s and 30s. The difficulties in standardization and the hostility within the psychology community formed a vicious cycle, impeding the progress of nationwide testing. Through this history, the article demonstrates not only the elevation of measurement to epistemic authority in modern China, but also how its promise was challenged by a diverse and rapidly changing society.

This article analyzes a popular meme that has spread rapidly among Chinese internet users in the last few years, ‘garlic chives’ ( jiucai), as a self-mockery of the bio-economic subject in contemporary China. This metaphor refers to those ordinary Chinese people who are constantly lured to participate in all kinds of economic activities, but whose investments are destined to be consumed by the establishment. Through a close study of this popular meme and the social conditions from which it arises, this (...) article demonstrates two main features of the Chinese economic subject that supports the state’s economic sovereignty: the thriving of self-sufficient and rule-abiding individuals, and the quality of these individuals as hard working and capable of producing wealth on their own. This article offers a critique of PRC’s post-socialist governmentality, and it provides insights about the relation between the biological and the political in our complicated world order. (shrink)

Readings in Chinese Women's Philosophical and Feminist Thought gathers 40 original writings on women by 32 authors (many of whom are women) from the Yuan dynasty to the Republics, an important 700-year historical period during which women's learning in China blossomed as a result of economic prosperity, the development of commercial printing, and the interaction between East and West. -/- Selections are made not only from canonical texts on women's virtues, but also from less orthodox literary works such as plays, (...) poetry, novels, essays, and revolutionary writings that illuminate the lived experience of women and the perception of gender. With many texts translated into English for the first time, this reader provides the context needed to understand them. It features: -/- - Chronologically organized readings in the sequence of the Yuan, Ming, Qing dynasties, and the Republics to demonstrate historical progression of thought (or the lack of) - Introductions to each section and chapter covering essential information about the authors and the cultural, historical, and philosophical background to their work - A chronology of dynasties, Republics, key events, and a map -/- Recovering discourse so often neglected in discussion of Chinese thought, this is the first collection to pay special attention to women-authored works from the late 13th to the early 21st century. By bringing these readings together in a single volume, it juxtaposes and compares female and male perspectives from the same time and creates a new narrative of Chinese philosophical thought.

This study examined how vocabulary, syntactic knowledge, and orthographic knowledge are related to comprehension monitoring and whether comprehension monitoring mediates the relations between these language skills and reading comprehension. Eighty-nine Chinese children were assessed on their vocabulary, syntactic knowledge, orthographic knowledge, and comprehension monitoring in Grade 1. Their reading comprehension skills were assessed in Grade 1 and Grade 3. Results showed that in Grade 1, comprehension monitoring mediated the relations between vocabulary and syntactic knowledge and reading comprehension. For Grade 3 (...) reading comprehension, syntactic knowledge in Grade 1 was the only significant predictor. These findings indicate that multiple language skills make direct and indirect contributions via comprehension monitoring to Chinese reading comprehension, and the relations would change as children’s reading skills develop.

Augustine of Hippo is often regarded as the champion of the doctrine of weakness of the will. John M. Rist in his 1994 'Augustine: Ancient Thought Baptized' draws an interesting analogy between Aristotle's 'akrasia' and Augustine's 'concupiscentia'. However, such an analogy without further qualification is defective and misleading because it implies that Augustine commits himself to the notion that since everyone is perpetually akratic and, thus, always morally blameworthy. I argue that, for Augustine, weakness of the will has equivocal meanings (...) and is manifested in four kinds of case--their scope goes far beyond Aristotle's discussion of 'akrasia' in Book Seven of the 'Nicomachean Ethics'. There are, therefore, considerable differences between Aristotle's and Augustine's account of weakness of the will. Consequently, for Augustine, moral responsibility for the moral agent also varies in each of the four cases. (shrink)

This article analyzes the current political predicament of Hong Kong by examining Nightmare Wallpaper, an art project composed of a series of automatic drawings made by local artist Pak Sheung Cheun. He made them while attending the court cases of political activists on trial, and the article further explores his subsequent efforts to transform this work into wallpaper prints, a series of installations, and a book. This political work, which is also very private, vividly and honestly demonstrates the artist’s intense (...) struggles, along with the despair felt by many in the city. The earnest self-reflection shown in the art does not give his audience a way out of the blind alley of the present but invites us to express ourselves and to connect with others. It is both a work of abjection and intersubjectivity, with no naïve expectation to reconcile the tensions between them. It shows, rather, a determination to participate in an uncertain future, combining the artist’s and the city’s capacity of meaning production and imagination. The Nightmare Wallpaper project also reveals how this artist, as part of a protest community, struggles to overcome binary thinking through an affirmation of becoming. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:206 Feminist Studies 46, no. 1. © 2020 by Feminist Studies, Inc. Pang Laikwan Identity Politics and Democracy in Hong Kong’s Social Unrest Hong Kong’s anti-Extradition Law Amendment Bill (anti-ELAB) movement began with legislation proposed in February 2019 to allow the transfer of fugitives to jurisdictions with which the city lacks formal extradition treaties. The law quickly attracted a tremendous amount of criticism and generated enormous anxiety because (...) mainland China was one of those jurisdictions.1 In fact, many believe that this bill was proposed to allow the government of the People’s Republic of China (PRC) to transfer wanted persons of any nationality from Hong Kong to China, subject to a legal process that many view as highly dubious. A large-scale anti-government movement exploded in June 2019 when pro-establishment legislators in Hong Kong insisted on passing it, and millions of people took to the streets. The government waited three months to withdraw the bill, only doing so after some of the most violent confrontations between civilians and the police in Hong Kong’s history. With Beijing’s 1. The law was originally proposed after a Hong Kong man, who killed his pregnant girlfriend in Taiwan, could not be extradited back to Taiwan to stand trial for the murder due to the lack of formal extradition laws. The proposed law, which would be applied to Hong Kong citizens, foreign residents, and even people passing through on business or as tourists, is being opposed due to the fear that it would be used to extradite Hong Kong political/civil rights activists and dissidents to China, where they would be harshly punished. Pang Laikwan 207 support, the Hong Kong government has doggedly resisted negotiating with the protestors over other demands, such as setting up an independent inquiry into police misconduct. As people have become completely disillusioned with the government and their own futures, tensions have increased. Collapsing many of the city’s socioeconomic problems into one cause, the anti-ELAB movement is primarily an anti-authoritarian impulse motivated by the unifying power of the term “Hongkongers.” As the movement unfolds, one of the most popular slogans, “Add Oil, Hongkongers!” (meaning “Keep going, Hongkongers!”) gradually transformed into “Rebel, Hongkongers!” and “Revenge, Hongkongers!” showing the protestors ’ anger about unrestrained police violence and the Beijing regime behind it. The militarization associated with these protests is both worrisome and symptomatic. This short essay analyzes this movement and uses it as a vehicle to disentangle social and political identity. My concern is about how a large-scale political movement can realign identities to generate power from the bottom. I use an Arendtian approach to ground my theoretical orientation, asking: How can political actions be understood as the pursuit of freedom to transcend one’s biological and social identity? From an intersectional feminist angle, if we are aware that social discrimination operates within a complex network of simultaneous discriminations, real social change can only be envisioned using a broad political canvas. Hong Kong’s anti-Extradition Law Amendment Bill movement provides such a setting. Division and Inclusion “The people” might be the emptiest, but also the most powerful, phrase in the modern political lexicon. It can be used by politicians to justify groundless proposals or criticisms, but it is also the foundation and source of legitimacy for all modern political institutions. Indeed, the most basic meaning of democracy is “rule of the people,” which is impossible to avoid in any democratic imagination. As has been widely seen throughout the world, however, “the people” is often attached to various degrees of xenophobia—hatred of outsiders in the name of in-group solidarity. While the Hong Kong protestors’ courageous demands for the PRC to honor its promise to grant the city a high degree of autonomy have gained widespread international sympathy, thorny social divisions persist within the movement. 208 Pang Laikwan While Hong Kong has never been a united society, the anti-ELAB protests—like most social movements—have been highly divisive, splitting Hong Kong people apart. Most obviously, “the people” are divided by their political identifications, forming a primary antagonism between those who support the protests and those who do not, usually described... (shrink)

The information age can be dated to the work of Norbert Wiener and Claude Shannon in the 1940s. Their work on cybernetics and information theory, and many subsequent developments, had a profound influence on reshaping the field of psychology from what it was prior to the 1950s. Contemporaneously, advances also occurred in experimental design and inferential statistical testing stemming from the work of Ronald Fisher, Jerzy Neyman, and Egon Pearson. These interdisciplinary advances from outside of psychology provided the conceptual and (...) methodological tools for what is often called the cognitive revolution but is more accurately described as the information-processing revolution. Cybernetics set the stage with the idea that everything ranging from neurophysiological mechanisms to societal activities can be modeled as structured control systems with feedforward and feedback loops. Information theory offered a way to quantify entropy and information, and promoted theorizing in terms of information flow. Statistical theory provided means for making scientific inferences from the results of controlled experiments and for conceptualizing human decision making. With those three pillars, a cognitive psychology adapted to the information age evolved. The growth of technology in the information age has resulted in human lives being increasingly interweaved with the cyber environment, making cognitive psychology an essential part of interdisciplinary research on such interweaving. Continued engagement in interdisciplinary research at the forefront of technology development provides a chance for psychologists not only to refine their theories but also to play a major role in the advent of a new age of science.

We propose a fast and reliable corner detector that can detect corners under non-uniform illumination and fuzzy mineshaft images effectively. First, we presented an inner mask that used only four pixels to determine the flat and corner regions of an image, which could eliminate unnecessary computation of flat regions, thus reducing computing cost. Second, we separated the corner regions into background and foreground and computed the separate corner threshold to settle non-uniform illumination. Third, we proposed a fast corner-detection algorithm to (...) compute the nucleus continuous contributive segment based on the corner state. Finally, we proposed two effective methods to remove the false corners. Experimental results showed that our approach has a better detection quality and is less time consuming than three other algorithms on an artificial image, a noisy image, and non-uniform images and could meet the real-time requirement of mineshaft applications.

A survey of women in two highly developed rural counties of China, Sichuan and Jiangsu Provinces, was carried out in late 1991, to gain information about demographic and economic change between 1980 and 1990. Three separate surveys were conducted: the first a questionnaire administered to married women aged 30–39, eliciting information about childbearing and contraception, as well as the social and economic background of the respondents; the second, focus group interviews emphasizing the motivation for childbearing. Official information about the selected (...) villages, townships and counties was also collected. (shrink)

Among the many silk manuscripts excavated from Changsha Mawangdui Tomb 3 in Hunan province in the winter of 1973, one text was named Wu xing [by contemporary scholars]. Twenty years later, in the winter of 1993, there was a text [of itself] titled Wu xing among the many bamboo slip texts excavated from Jingmen Guodian Tomb 1 in Hubei.

In October 1993, a cache of bamboo slips written in the Chu script was excavated from a Warring States period tomb in the village of Guodian in the city of Jingmen in the province of Hubei. After separation and arrangement by experts, the photo plates of the Chu slips and their annotations were published this May by Wenwu Press in the book called Guodian Chu mu zhujian.

Among the most influential and well-known experiments of the 19th century was the generation and detection of electromagnetic radiation by Heinrich Hertz in 1887–1888, work that bears favorable comparison for experimental ingenuity and influence with that by Michael Faraday in the 1830s and 1840s. In what follows, we pursue issues raised by what Hertz did in his experimental space to produce and to detect what proved to be an extraordinarily subtle effect. Though he did provide evidence for the existence of (...) such radiation that other investigators found compelling, nevertheless Hertz’s data and the conclusions he drew from it ran counter to the claim of Maxwell’s electrodynamics that electric waves in air and wires travel at the same speed. Since subsequent experiments eventually suggested otherwise, the question arises of just what took place in Hertz’s. The difficulties attendant on designing, deploying, and interpreting novel apparatus go far in explaining his results, which were nevertheless sufficiently convincing that other investigators, and Hertz himself, soon took up the challenge of further investigation based on his initial designs.
