In this paper, finite-time tracking problem of nonholonomic mobile robots for a moving target is considered. First of all, polar coordinates are used to characterize the distance and azimuth between the moving target and the robot. Then, based on the distance and azimuth transported from the sensor installed on the robot, a finite-time tracking control law is designed for the nonholonomic mobile robot by the switching control method. Rigorous proof shows that the tracking error converges to zero in a finite (...) time. Numerical simulation demonstrates the effectiveness of the proposed control method. (shrink)

It is commonly held that implicit learning is based largely on familiarity. It is also commonly held that familiarity is not affected by intentions. It follows that people should not be able to use familiarity to distinguish strings from two different implicitly learned grammars. In two experiments, subjects were trained on two grammars and then asked to endorse strings from only one of the grammars. Subjects also rated how familiar each string felt and reported whether or not they used familiarity (...) to make their grammaticality judgment. We found subjects could endorse the strings of just one grammar and ignore the strings from the other. Importantly, when subjects said they were using familiarity, the rated familiarity for test strings consistent with their chosen grammar was greater than that for strings from the other grammar. Familiarity, subjectively defined, is sensitive to intentions and can play a key role in strategic control. (shrink)

Students and teachers of Chinese history and philosophy will not want to miss Daniel Gardner's accessible translation of the teachings of Chu Hsi —a luminary of the Confucian tradition who dominated Chinese intellectual life for centuries. Homing in on a primary concern of our own time, Gardner focuses on Chu Hsi's passionate interest in education and its importance to individual development. For hundreds of years, every literate person in China was familiar with Chu Hsi's teachings. They informed the curricula of (...) private academies and public schools and became the basis of the state's prestigious civil service examinations. Nor was Chu's influence limited to China. In Korea and Japan as well, his teachings defined the terms of scholarly debate and served as the foundation for state ideology. Chu Hsi was convinced that through education anyone could learn to be fully moral and thus travel the road to sagehood. Throughout his life, he struggled with the philosophical questions underlying education: What should people learn? How should they go about learning? What enables them to learn? What are the aims and the effects of learning? Part One of _Learning to Be a Sage_ examines Chu Hsi's views on learning and how he arrived at them. Part Two presents a translation of the chapters devoted to learning in the _Conversations of Master Chu_. (shrink)

Most binaural speech source localization models perform poorly in unprecedentedly noisy and reverberant situations. Here, this issue is approached by modelling a multiscale dilated convolutional neural network. The time-related crosscorrelation function and energy-related interaural level differences are preprocessed in separate branches of dilated convolutional network. The multiscale dilated CNN can encode discriminative representations for CCF and ILD, respectively. After encoding, the individual interaural representations are fused to map source direction. Furthermore, in order to improve the parameter adaptation, a novel semiadaptive (...) entropy is proposed to train the network under directional constraints. Experimental results show the proposed method can adaptively locate speech sources in simulated noisy and reverberant environments. (shrink)

Quarantine and isolation at extended length, although considered as highly effective countermeasures for the novel coronavirus which started at the end of 2019, can have great impact on individual's mental health, especially emotional state. The present research recruited 5,115 participants from the general public across 32 provinces and autonomous regions in China in an online survey study, about 20 days after the lockdown of the epicenter, to investigate the relationship between the length of the quarantine and negative affect, as well (...) as the mediating roles of negative cognition, and the moderating roles of dispositional optimism, tolerance of uncertainty, social support, and healthy behavior. The results showed that: Worry and anticipation mediated the relationship between quarantine length and depression and anxiety; Dispositional optimism moderated the path coefficients of quarantine length to worry, worry to anxiety, and anticipation to depression; Tolerance of uncertainty moderated the path coefficient of worry to anxiety; Social support moderated the path coefficient of anticipation to anxiety. In conclusion, during quarantine, dispositional optimism, uncertainty tolerance, and social support can buffer the direct or indirect effects of quarantine length on depression and anxiety. These findings could have profound implications on the societal responses to COVID-19 and future pandemics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Teaching the Trinity:Scripture and Performance of the Psychological Analogy in Aquinas's Summa TheologiaeZane E. ChuTeaching the Trinity, for St. Thomas Aquinas, takes its point of departure from Sacred Scripture. He makes this explicit at the outset of the Trinitarian treatise in the Summa theologiae, citing Christ's words at John 8:42, "from God I proceeded," and affirming, "divine Scripture in the things of divinity, uses words that pertain to procession."1 (...) The order of teaching then continues through speculative effort to give an account of the scriptural witness to the distinction of persons in God, in order to return to the same Scripture with a deeper grasp of its meaning.2Aquinas is a master of the sacred page, and his basic pedagogy for theology involves the "exercises of Sacred Scripture" of reading, disputing, and preaching.3 Recent scholarship draws attention to his reading of Scripture [End Page 1149] expressed in biblical commentaries as foundational for his teaching and as an interpretive context for his summative works.4 My purpose is to illustrate this basic pedagogy in the Trinitarian treatise of the Summa theologiae, taking the Lectura super Ioannem as an interpretive context for the analogies of word and love—the psychological analogy—for the Trinity. Most scholarly discussion of the psychological analogy elaborates on its theoretical aspects, with some attention to its scriptural foundation.5 I wish to show the priority of Scripture in Aquinas's employment of this analogy in three respects, namely, its foundation in exegesis, performative aspects, and orientation toward preaching.My investigation focuses on question 27 of the prima pars alongside pertinent sections of the Super Ioannem. I argue that citations from the Gospel of John (8:42, 15:26, and 14:16) in the sed contras of articles 1 and 3 function to ground the psychological analogy in scriptural exegesis and to prompt its performance. Turning to the corresponding commentary shows Aquinas leading the student to knowledge of Christ as divine Word and to love of him from the Holy Spirit that both leads to and follows upon such knowledge. This provokes an affective experience of loving Christ in knowing his divinity that is an actual performance of the psychological analogy. The magisterial responses then use this affective experience as a basis to facilitate a grasp of the analogy, the articulation of which is a further guided performance that reflects on this experience. Aquinas teaches the Trinity by exercising the student both affectively and intellectually in its scriptural foundation for a deeper grasp that prepares for preaching. I develop my argument in three [End Page 1150] main steps. First, I specify the place of Scripture in Aquinas's teaching and review the composition of the Trinitarian treatise. Then, I examine the first four articles of question 27 and corresponding sections of the Super Ioannem, in the order of the analogies of word and of love. Lastly, I consider Aquinas's treatment of the Holy Spirit's proper name of Love and subsequent preaching to illustrate Scripture as a point of arrival through performance of the psychological analogy.The Place of Scripture in Aquinas's TeachingFor Aquinas, Scripture is placed within his broader practice of sacra doctrina or holy teaching, attention to which assists in demonstrating how the Johannine citations ground the psychological analogy in Scripture and prompt its performance. Sacra doctrina has a primarily pastoral orientation, namely, to form Dominicans for preaching and hearing confessions.6 Though more speculative than practical, sacra doctrina as speculation or contemplation of the truth of Christian faith contained in Scripture is to be handed on to others.7 This requires training in the scriptural exercises of reading and disputing as preparation for preaching. These may be taken as "spiritual exercises" that engage not only thought, but also affectivity in service of personal transformation for the preacher's way of life.8 Aquinas's practice of sacra doctrina begins with reading Scripture as expressed in biblical commentaries, and develops in the Summa theologiae, which accesses Scripture through citations to offer a summative grasp of the truth contained therein. Here, I review the formal aspects of Aquinas's teaching from Scripture in these texts... (shrink)

Of the many proposals for inferring genetic regulatory structure from microarray measurements of mRNA transcript hybridization, several aim to estimate regulatory structure from the associations of gene expression levels measured in repeated samples. The repeated samples may be from a single experimental condition, or from several distinct experimental conditions; they may be “equilibrium” measurements or time series; the associations may be estimated by correlation coefficients or by conditional frequencies (for discretized measurements) or by some other statistic. This paper describes two (...) elementary statistical difficulties for all such procedures, no matter whether based on Bayesian updating, conditional independence testing, or other machine learning procedures such as simulated annealing or neural net pruning. One difficulty obtains if large numbers of cells are aggregated in a measurement of expression levels from a common population of cells; the other obtains if small numbers of cells are aggregated or if samples are separately aggregated over different populations of cells.

The environmentally friendly or ‘sustainable’ products have been launched in various markets in response to the growing concerns for the environmental deterioration and the alarming effects of climate change in past years. However, the uptake of green products does not seem to fully reflect the self-claimed pro-environmental concerns and attitudes. Consumers who profess to be environmentally conscious and believe they could help slow down environmental deterioration do not necessarily purchase eco-friendly products. This discrepancy between behaviour and attitude has been termed (...) as ‘intention-behaviour gap’ or ‘green gap’. This study aims at exploring the green gap in the purchases of high-involvement products such as skincare products. Focus groups and thematic analysis were conducted. It was found that environmental concern was virtually non-existent in making purchase decisions with regard to skincare products because the perceived product effectiveness is found to be the key determinant of the choice of skincare products. Other factors such as weak social norm, weak perceived consumer effectiveness, and a sense of powerlessness facing the environment degradation, to some degree, attribute to the consumers’ justification of their non-green consumption practices. Implications for closing the gap have been drawn for marketing practitioners and policy makers. Directions for future research are also provided. (shrink)
