In speaker recognition systems, feature extraction is a challenging task under environment noise conditions. To improve the robustness of the feature, we proposed a multiscale chaotic feature for speaker recognition. We use a multiresolution analysis technique to capture more finer information on different speakers in the frequency domain. Then, we extracted the speech chaotic characteristics based on the nonlinear dynamic model, which helps to improve the discrimination of features. Finally, we use a GMM-UBM model to develop a speaker recognition system. (...) Our experimental results verified its good performance. Under clean speech and noise speech conditions, the ERR value of our method is reduced by 13.94% and 26.5% compared with the state-of-the-art method, respectively. (shrink)

The power grid is an important connection between power sources and users, responsible for supplying and distributing electric energy to users. Modern power grids are widely distributed and large in scale, and their security faces new problems and challenges. Information entropy theory is an objective weighting method that compares the information order of each evaluation index to judge the weight value. With the wide application of entropy theory in various disciplines, the subject of introducing entropy into the power system has (...) been gradually concerned. This article aims to study the smart terminal security technology of the power grid perception layer based on information entropy data mining. This article analyzes its related methods and designs a smart terminal for the power grid. On this basis, a data analysis platform is built and a safety plan is designed. The result is that the average absolute error, root mean square error, average absolute percentage error, and mean square error of the platform's power load forecast are 1.58, 1.96, 8.2%, and 3.93, respectively. These error values are within the ideal range, and the data processing ability is strong. The packet loss rate of the adversary's eavesdropping was tested, and the average packet loss rates at locations a, b, c, and d were 1.05, 1.2, 1.81, and 2.2%, respectively. Data packets will be definitely lost, so the platform is highly secure. (shrink)

Despite the rising interest in environmental strategies, few studies have examined how managerial cognition of such strategies influences actual innovation capability development. Taking a managerial cognition perspective, this study investigates how managers’ perceptions of institutional pressures relate to their focus on proactive environmental strategy, which in turn affects firms’ realized innovation capability. The findings from a primary survey and three secondary datasets of publicly listed companies in China reveal that managers’ perceived business and social pressures are positively associated with their (...) focus on proactive environmental strategy, which consequently fosters innovation capability development. Moreover, state ownership and government administrative control weaken the impact of managerial focus on proactive environmental strategy on innovation capability. These findings have important implications for how managerial cognition supports environmental strategy and organizational capability building under the influence of institutional pressures and government intervention.

「惻隱之心，仁也；羞惡之心，義也；恭敬之心，禮也；是非之心，智也。仁義禮智，非由外鑠我也，我固有之也，弗思耳矣。」 （《孟子．告子上》） 孔子為挽救周文，創造性地闡釋「仁」的觀念；孟子依此，主張人性本善，提出四端之心，擴而充之，即成仁義禮智，是為中華傳統文化裏重要的道德基礎。爾後多位思想家加以深化、詮釋、演繹，令其內涵更充沛、更豐盈。 本書介紹中國古代各思想家對仁、義、禮、智的論說，嘗試釐清四種觀念的歷史脈絡和演變，並對不同思想家的說法加以比較，務求讀者能概括認識儒家的核心所在。.

Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments (...) about different and unrelated visual stimulus properties. We found that inter-individual differences were strongly correlated between the two tasks for metacognitive ability but not objective performance. Such stability of an individual’s metacognitive ability across different perceptual tasks indicates a general mechanism supporting metacognition independent of the specific task. (shrink)

This study attempts to answer the question why Confucianism, the dominant “teaching” among the Three Teachings, is not a religion in contemporary China, unlike the other two “teachings,” Buddhism and Daoism. By examining this phenomenon in the social-historical context, this study finds its origin in Orientalism. The Orientalist conceptualization of religion became part of the New Culture discourse at the turn of the twentieth century. While China has undergone tremendous social changes over the past century, the old discourse remains.

Editor's AbstractThis essay presents Mainland New Confucianism (MNC) as diverse but distinctive, as still in a process of maturation but already with a clear direction. According to Chen, MNC is a rejection of the twin modernist narratives of the left (revolution) and the right (enlightenment) in favor of a narrative that downplays the ruptures associated with the May Fourth Movement and instead seeks to reconnect to China's past values and traditions.

Drawing on social exchange theory and benevolent leadership literature, we show how the largesse associated with benevolent leadership can cause subordinates to feel obliged to undertake illegitimate tasks assignments that go beyond their job duties. The hypotheses are tested in a scenario experimental study and a multisource, time-lagged field survey. Both studies indicate that benevolent leadership evokes indebtedness in subordinates (called felt obligation), which is then indirectly related to their willingness to undertake illegitimate tasks. The second study shows that subordinates (...) who try to avoid actions that damage relationships (called disintegration avoidance) and those who feel job insecurity are most willing to perform illegitimate assignments. Practical implications for curbing workplace exploitation are discussed. (shrink)

The common law's approach in the law of unjust enrichment is to enumerate specific «unjust factors» as permissible causes of action in claims for restitution. This approach has come under attack, inter alia, for being unnecessarily complicated. The claim is that the civilian approach, with its single ground of absence of legal cause for the transfer, is preferable since the operative unjust factor in any particular case is irrelevant to the restitutionary response. In defence of the common law's approach, this (...) article tenders four aspects of the restitutionary response which, it is claimed, are illuminated by reference to the nature, context, and effect of the operative unjust factor in any particular case. They are: (i) the availability of the defence of change of position; (ii) the justifiability of certain «bars» on rescission and the permissible mode of mutual restitution on rescission; (iii) the appropriate measure of enrichment where restitution is, or must be, effected in money; and (iv) two possible justifications for the controversial remedy of partial rescission.

In the fifth year of the reign of Shaoxi [in the Song dynasty]—in other words, in the year 1194 A.D.—Zhu Xi was returning to his home province after he had been relieved of his position at court as daizhi shijiang when, in the eleventh month of that year he came to Yushan county in Jiangxi Province. The governor of the district invited Master Zhu to give a number of lectures at the local county school, and Master Zhu complied, discoursing on (...) essential teachings in response to the questions that were raised by the students as well as in response to the lectures given by other scholars. At one point, the record says, the scholar Cheng Gong1 rose to ask the question: "Philosophers prior to the Three Ages only spoke about zhong and ji ; how come, then, that when it came to the time of the dialogues of those in the school of Confucius, everything seemed to revolve around the word ren ?" Master Zhu replied: "The discussions of zhong and of ji have often tended to make people misunderstand the meaning of what they were actually saying; alas, we do not ourselves have the leisure here to discuss all of that in detail.".

Today's educational environment forms the stage for a host of debates, many of which centre on the use of standardized assessment in the classroom. With this push towards standardization, less time is being devoted to incorporating ?experiential? knowledge, or that knowledge which comes from hands?on, travel, natural and other worldly experiences, into the learning environment. William Wordsworth and Thomas Hardy, two somewhat unlikely sources of educational insight, do have a pertinent message to add to this ongoing educational discussion. The two (...) authors, through their personal experiences and through their literary works, draw from and examine the roles of formal education and the functions of various facets of knowledge in education. They exemplify the importance of finding a balance between formal educational experiences and informal avenues of education. Both men remind society that without the incorporation of experiential knowledge into the educational experience, students cannot reach the full potential of their intellectual, emotional, spiritual and social growth. Through an examination of the lives and works of Wordsworth and Hardy, the importance of non?formal, non?standardized experiences is reasserted at a time when it is of utmost importance to evaluate the components that make up modern education.

Kepler's Somnium is a fantastical story about the world on the moon. It presents a heliocentric world-picture established through a total conversion of the meaning and place of observation in the hierarchy of knowledge. This epistemological program is construed through a critical adaptation of Lucian's "True Story," and Plutarch's "The Face on the Moon." Utilizing his new optics, embodied in the Camera obscura, Kepler inverts the meaning of these classical texts together with the reader's point of view. Astronomical knowledge is (...) vindicated and scientific observation is the only way out of an obscure and mannerist dream. (shrink)

The fiscal imbalance between the central and local governments under fiscal centralization may motivate local governments to pass tax burdens on firms. The causal identification of the tax system reform and the sustainable export innovation behavior of firms are of great significance. This study uses the income tax sharing policy of China to examine the impact of fiscal centralization on the sustainable export innovation behavior of firms. We find that this tax reform has significantly inhibited the increase of the export (...) value-added rate of firms, and has an increasing trend with the share ratio between the Central Government and the local government. Moreover, this effect mainly comes from the crowding-out effect of imported intermediate goods on domestic intermediate goods. The tests show that the above conclusions are consistent with the general logic of local governments. When they face greater downward fiscal pressure, they will further pass the tax burden on local firms and force the firms to promote their export performance to expand the tax base. This short-sighted behavior of replacing “quality improvement” with “quantity increase” is an important factor that affects the sustainable export innovation behavior of firms and the climb in the global value chain.

Our paper draws attention to a neglected channel of corruption—the bribe payments by state-owned enterprises. This is an important phenomenon as bribe payments by SOEs fruitlessly waste national resources, compromising public welfare and national prosperity. Using a large dataset of 30,249 firms from 50 countries, we show that, in general, SOEs are less likely to pay bribes for achieving organizational objectives owing to their political connectivity. However, in deteriorated institutional environments, SOEs may be subjected to potential managerial rent-seeking behaviors, which (...) disproportionately increase SOE bribe propensity relative to privately owned enterprises. Specifically, our findings highlight the importance of fostering democracy and rule of law, reducing prevalence of corruption and shortening power distance in reducing the incidence of SOE bribery.

Professor Chen Ning Yang, an eminent contemporary physicist, was Professor at the Institute for Advanced Study, Princeton, New Jersey, from 1955 to 1966, and Albert Einstein Professor of Physics at the State University of New York at Stony Brook until his retirement in 1999. He has been Distinguished Professor-at-Large at the Chinese University of Hong Kong since 1986 and Professor at Tsinghua University, Beijing, since 1998. Since receiving his PhD from the University of Chicago in 1948, Prof Yang has (...) made great impacts in both abstract theory and phenomenological analysis in modern physics. In 1983, he published "Selected Papers (1945-1980), With Commentary". It has been considered by Freeman Dyson as one of his favorite books. The present book is a sequel to that earlier volume. It is a collection of his personally selected papers (1971-2012) supplemented by his insightful commentaries. Its contents reflect Professor Yang's changing interests after he reached age sixty. It also includes commentaries written by him in 2011 when he is 89 years old. The papers and commentaries in this unique collection comprise a remarkable personal and professional chronicle, shedding light on both the intellectual development of a great physicist and on the nature of scientific inquiry.

Thomas Kuhn's Structure of Scientific Revolutions became the most widely read book about science in the twentieth century. His terms 'paradigm' and 'scientific revolution' entered everyday speech, but they remain controversial. In the second half of the twentieth century, the new field of cognitive science combined empirical psychology, computer science, and neuroscience. In this book, the theories of concepts developed by cognitive scientists are used to evaluate and extend Kuhn's most influential ideas. Based on case studies of the Copernican revolution, (...) the discovery of nuclear fission, and an elaboration of Kuhn's famous 'ducks and geese' example of concept learning, this volume, first published in 2006, offers accounts of the nature of normal and revolutionary science, the function of anomalies, and the nature of incommensurability.

To me, becoming attached to Dushu was a "historical event" of no mean significance, because doing so has ever since profoundly affected my academic career.

"Scholar of the humanities" is not a title of honor; it is only a choice of profession. Hence, those "erstwhile scholars" who have already gone into politics or business are not discussed in the present article. Instead of touching on such hot topics as professors selling meat pies, buying and selling automobiles, entering people's political consultative conferences, or taking government posts, this article considers the destiny and possible options of scholars who are willing to engage in humanity studies and are (...) still doing so, for the latter are more perplexed and more at loss and deserve more understanding and sympathy.

This article examines various positions on whether children should be allowed to play in late imperial China. Demonstrating distinctly different views from Neo-Confucian thinkers, professional genre painters of “Children at Play” ( yingxi tu 嬰戲圖), and the emerging pediatric specialists, the article maintains that clearly multi-vocal forces coexisted during the Song Dynasty, including a persuasive child-favoring stance that remains unique in global humanities on this issue.

In his Knowledge and Belief (1962), Hintikka establishes his system of epistemic logic with the KK (Knowing that One Knows, in symbols, Kp→KKp) principle (KK for short). However, his system of epistemic logic and the KK principle are grounded upon his strong notion of knowledge, which requires that knowledge is infallible, that is, it makes further inquiry pointless, and becomes ‘discussion-stopper’; knowledge implies truth, to wit, cognitive agents will not be mistaken in their knowledge; cognitive agents will be ‘perfect logicians’, (...) i.e. they have infinitive capability of logical inference. Hintikka calls the argument for KK from the strong notion of knowledge as the ‘transcendental argument’ for KK. Obviously, the strong notion of knowledge is far away from our ordinary conception of knowledge; based on such a strong sense of knowledge, epistemic logic has met the problem of logical omnipotence, and is difficult to apply in our ordinary cognitive practice. Moreover, there is no close connection of the KK principle with internalism or externalism. (shrink)

All concepts, methods, and techniques of the philosophy of language arise from its conceptions of language. Conceptions of language have determined the character of the philosophy of language and the direction of its philosophical research. Various schools and currents within the philosophy of language differ from each other, mainly in the way they understand the referential character of the sign—that is, the relationship between the meaning of a word and its referential object.

The Sapir-Whorf hypothesis asserts that people who organize their experience with the help of different languages can have different pictures of the world.

This study examines the effect of teaching ethics and the form of code of ethics on auditors’ ethical decision making. We draw upon Rest’s decision-making model and Hunt and Vitell’s theory of marketing ethics to assist us with this examination. We use accounting students as substitutes for auditors in this study to enhance its internal validity as students are “subjects who would not already have detailed knowledge and experience of the Code”. The research method includes a survey and an experiment (...) in the study. A between-subjects survey design with a sample of 271 students and a within-subjects experimental design with a sample of 146 students are used. A confirmatory factor analysis is conducted before other statistical methods are performed. Our results show that teaching codes of ethics improves accounting students’ awareness of audit independence issues and their ethical judgments and intentions. However, the form of a code of ethics does not make any significant difference in terms of the participants’ awareness of audit independence and their ethical judgments and intentions. Our study contributes to the debate on the effectiveness of principles-based versus rules-based codes of ethics and the importance of teaching ethics in non-Western economies. (shrink)
