In special application scenarios, such as portable anesthesia depth monitoring, portable emotional state recognition and portable sleep monitoring, electroencephalogram (EEG) signal acquisition equipment is required to be convenient and easy to use. It is difficult to remove electrooculogram (EOG) artifacts when the number of EEG acquisition channels is small, especially when the number of observed signals is less than that of the source signals, and the overcomplete problem will arise. The independent component analysis (ICA) algorithm commonly used for artifact removal (...) requires the number of basis vectors to be smaller than the dimension of the input data due to a set of standard orthonormal bases learned during the convergence process, so it cannot be used to solve the overcomplete problem. The empirical mode decomposition method decomposes the signal into several independent intrinsic mode functions so that the number of observed signals is more than that of the source signals, solving the overcomplete problem. However, when using this method to solve overcompleteness, the modal aliasing problem will arise, which is caused by abnormal events such as sharp signals, impulse interference, and noise. Aiming at the above problems, we propose a novel EEG artifact removal method based on discrete wavelet transform, complete empirical mode decomposition for adaptive noise (CEEMDAN) and ICA in this paper. First, the input signals are transformed by discrete wavelet (DWT), and then CEEMDAN is used to solve the overcomplete and mode aliasing problems, meeting the a priori conditions of the ICA algorithm. Finally, the components belonging to EOG artifacts are removed according to the sample entropy value of each independent component. Experiments show that this method can effectively remove EOG artifacts while solving the overcomplete and modal aliasing problems. (shrink)

The Chinese academic assessment and incentive system drew mixed responses from academia. In the essay the author tried to explain why the current assessment system is appropriate in China and an opportunistic behavior in Chinese academia is exposed.

Scientists normally earn less money than many other professions which require a similar amount of training and qualification. The economic theory of marginal utility and cost-benefit analysis can be applied to explain this phenomenon. Although scientists make less money than entertainment stars, the scientists do research work out of their interest and they also enjoy a much higher reputation and social status in some countries.

Machine learning algorithms bring out an under-appreciated puzzle of discrimination, namely figuring out when a decision made on the basis of a factor correlated with race is a decision made on the basis of race. I argue that prevailing approaches, which are based on identifying and then distinguishing among causal effects of race, in their metaphysical timidity, fail to get off the ground. I suggest, instead, that adopting a constructivist theory of race answers this puzzle in a principled manner. On (...) what I call a “thick constructivist” account of race, to be raced is to be socially positioned in the way indicated by a certain set of statistical regularities on the basis of particular phenotypical traits. A thick constructivist sees that acting on the basis of correlations that constitute race qua social position just is acting on the basis of race, because races just are social positions that subject their member individuals to a particular matrix of social relations that define the raced position. This conclusion has considerable ramifications for our understanding of discrimination, algorithms and beyond. (shrink)

University students having high entrepreneurial intention while not transferring into actual entrepreneurial behavior is a contradictory issue in need of in-depth research. To explore the successive development mechanism of the entrepreneurial process, this study constructed a moderated mediation model to examine whether entrepreneurial commitment from three dimensions mediated the relationship between entrepreneurial intention and behavior, and whether this mediating process was moderated by family support. A survey was conducted among university students from six major universities in south China using the (...) snowball sampling approach. A total of 469 valid responses were obtained. Structural equation modeling was adopted for data analysis. According to the results of the confirmatory factor analysis, it was found that entrepreneurial intention had both direct and indirect positive effects on entrepreneurial behavior, while entrepreneurial commitment worked as the mediator, and family support moderated the relationship between entrepreneurial intention and behavior. Results indicated that entrepreneurial commitment bridged the path from entrepreneurial intention to behavior, and family support created the boundary effect. This finding highlights the importance of guiding students through entrepreneurial commitment toward entrepreneurial behavior, and pays special attention to the crucial role of family support under the national strategy.

That a symbolic object or work of art participates in what it signifies, as a part within a whole, was a controversial claim discussed with particular intensity in the wake of Immanuel Kant's Critique of Judgment. It informed the aesthetic theories of a constellation of writers in Jena and Weimar around 1800, including Moritz, Goethe, Schelling and Hegel. Yet the twin concepts of symbol and intuition were not only tools of literary and mythological criticism: they were integral even to questions (...) of epistemology and methodology in the fields of theology, metaphysics, history and natural philosophy. The international contributors to this volume further explore how both the explanatory potential and peculiar dissatisfactions of the symbol entered the Anglo-American discourse, focusing on Coleridge, Crabb Robinson and Emerson. Contemporary debates about the claims of symbolic as opposed to allegorical art are kept in view throughout. (shrink)

Ursachen spielen im Alltag und in der Wissenschaft eine zentrale Rolle. Wir stützen uns auf Ursachenwissen wenn wir Vorhersagen machen, wenn wir Phänomene erklären, wenn wir in die Natur eingreifen und wenn wir Verantwortung zuschreiben. Aber was heißt es, dass etwas die Ursache eines Ereignisses ist? Dieses Buch gibt einen kurzen Überblick über historische Positionen, die auch für heutige Debatten noch relevant sind. Im Hauptteil wird ein systematischer Überblick über die wesentlichen Theorien von Ursachen gegeben: die Regularitätstheorie, die kontrafaktische Theorie, (...) die Prozesstheorie und neuere Formen des Interventionismus. Zwei Fragestellungen spielen bei der Bewertung der verschiedenen Ansätze eine zentrale Rolle: Wie wird erklärt, dass Ursachen ihre Wirkungen,erzwingen‘? Wie wird verständlich gemacht, dass Ursachen Teil einer Welt sein können, die durch die Physik beschrieben wird? Schließlich entwickelt der Verfasser eine neue Variante einer Prozesstheorie, die darauf verzichtet Prozesse physikalisch auszuzeichnen. Die Neuauflage enthält eine deutliche Weiterentwicklung der Position des Verfassers. Zudem wurde der gesamte Text durchgesehen sowie neu erschienene Literatur berücksichtigt. (shrink)

Among world's three major philosophic traditions, Chinese philosophy excels in ethical discourse. As a collective wisdom on a par with Aristotle's "Ethics" and Kant's "Critique of Practical Reason", Chinese philosophy now needs to be systematized and developed. Today, Chinese philosophy per se has often been reduced to the historical approach to it, hence its slower development in comparison with European and Indian philosophies. The author of this book avails himself of Kant's model of human psychic structure, synthesizes the basic elements (...) of Chinese philosophy into a rigorous theoretical framework, and presents a panoptic view of the edifice of traditional Chinese philosophy.
