As an important component to promote the development of affective brain–computer interfaces, the study of emotion recognition based on electroencephalography (EEG) has encountered a difficult challenge; the distribution of EEG data changes among different subjects and at different time periods. Domain adaptation methods can effectively alleviate the generalization problem of EEG emotion recognition models. However, most of them treat multiple source domains, with significantly different distributions, as one single source domain, and only adapt the cross-domain marginal distribution while ignoring the (...) joint distribution difference between the domains. To gain the advantages of multiple source distributions, and better match the distributions of the source and target domains, this paper proposes a novel multi-source joint domain adaptation (MSJDA) network. We first map all domains to a shared feature space and then align the joint distributions of the further extracted private representations and the corresponding classification predictions for each pair of source and target domains. Extensive cross-subject and cross-session experiments on the benchmark dataset, SEED, demonstrate the effectiveness of the proposed model, where more significant classification results are obtained on the more difficult cross-subject emotion recognition task.

It is not only difficult to be a sports expert but also difficult to grow from a sports expert to a sports elite. Professional athletes are often concerned about the differences between an expert and an elite and how to eventually become an elite athlete. To explore the differences in brain neural mechanism between experts and elites in the process of motor behavior and reveal the internal connection between motor performance and brain activity, we collected and analyzed the electroencephalography findings (...) of 14 national archers and 14 provincial archers during aiming and resting states and constructed the EEG brain network of the two archer groups based on weighted phase lag index; the graph theory was used to analyze and compare the network characteristics via local network and global network topologies. The results showed that compared with the expert archers, the elite archers had stronger functional coupling in beta1 and beta2 bands, and the difference was evident in the frontal and central regions; in terms of global characteristics of brain network topology, the average clustering coefficient and global efficiency of elite archers were significantly higher than that of expert archers, and the eigenvector centrality of expert archers was higher; for local characteristics, elite archers had higher local efficient; and the brain network characteristics of expert archers showed a strong correlation with archery performance. This suggests that compared with expert archers, elite archers showed stronger functional coupling, higher integration efficiency of global and local information, and more independent performance in the archery process. These findings reveal the differences in brain electrical network topologies between elite and expert archers in the archery preparation stage, which is expected to provide theoretical reference for further training and promotion of professional athletes.

Objective: Tangent Space Mapping using the geometric structure of the covariance matrices is an effective method to recognize multiclass motor imagery. Compared with the traditional CSP method, the Riemann geometric method based on TSM takes into account the nonlinear information contained in the covariance matrix, and can extract more abundant and effective features. Moreover, the method is an unsupervised operation, which can reduce the time of feature extraction. However, EEG features induced by MI mental activities of different subjects are not (...) the same, so selection of subject-specific discriminative EEG frequency components play a vital role in the recognition of multiclass MI. In order to solve the problem, a discriminative and multi-scale filter bank tangent space mapping algorithm is proposed in this article to design the subject-specific Filter Bank so as to effectively recognize multiclass MI tasks. Methods: On the 4-class BCI competition IV-2a dataset, first, a non-parametric method of multivariate analysis of variance based on the sum of squared distances is used to select discriminative frequency bands for a subject; next, a multi-scale FB is generated according to the range of these frequency bands, and then decompose multi-channel EEG of the subject into multiple sub-bands combined with several time windows. Then TSM algorithm is used to estimate Riemannian tangent space features in each sub-band and finally a liner Support Vector Machines is used for classification. Main Results: The analysis results show that the proposed discriminative FB enhances the multi-scale TSM algorithm, improves the classification accuracy and reduces the execution time during training and testing. On the 4-class BCI competition IV-2a dataset, the average session to session classification accuracy of nine subjects reached 77.33 ± 12.3%. When the training time and the test time are similar, the average classification accuracy is 2.56% higher than the latest TSM method based on multi-scale filter bank analysis technology. When the classification accuracy is similar, the training speed is increased by more than three times, and the test speed is increased two times more. Compared with Supervised Fisher Geodesic Minimum Distance to the Mean, another new variant based on Riemann geometry classifier, the average accuracy is 3.36% higher, we also compared with the latest Deep Learning method, and the average accuracy of 10-fold cross validation improved by 2.58%. Conclusion: Research shows that the proposed DMFBTSM algorithm can improve the classification accuracy of MI tasks. Significance: Compared with the MFBTSM algorithm, the algorithm proposed in this article is expected to select frequency bands with good separability for specific subject to improve the classification accuracy of multiclass MI tasks and reduce the feature dimension to reduce training time and testing time.

Common spatial pattern is an effective algorithm for extracting electroencephalogram features of motor imagery ; however, CSP mainly aims at multichannel EEG signals, and its effect in extracting EEG features with fewer channels is poor—even worse than before using CSP. To solve the above problem, a new combined feature extraction method has been proposed in this study. For EEG signals from fewer channels, wavelet packet transform, fast ensemble empirical mode decomposition, and local mean decomposition were used to decompose the band-pass (...) filtered EEG into multiple time–frequency components, and the corresponding components were selected according to the frequency characteristics of MI or the correlation coefficient between its time–frequency components and the original EEG signal. Furthermore, phase space reconstruction was performed on the selected components after the three time-frequency decompositions, the maximum Lyapunov index was calculated, and the features were reconstructed; then, CSP projection mapping was used for the reconstructed features. The support vector machine probability output model was trained by the obtained three mappings. Probability outputs by three different support vector machines were then obtained. Finally, the classification of test samples was determined by the fusion of the Dempster–Shafer evidence theory at the decision level. The results showed that the accuracy of the proposed method was 95.71% on data set III of BCI competition II, which was 2.88% higher than the existing methods. On data set IIb of BCI competition IV, the average accuracy was 86.60%, which was 2.3% higher than the existing methods. This study verified the effectiveness of the proposed method and provided an approach for the research and development of the MI-BCI system based on fewer channels. (shrink)

Mindfulness and accordant interventions are often used as complementary treatments to psychological or psychosomatic problems. This has also been gradually integrated into daily lives for the promotion of psychological well-being in non-clinical populations. The experience of mindful acceptance in a non-judgmental way brought about the state, which was less interfered by a negative effect. Mindfulness practice often begins with focused attention meditation restricted to an inner experience. We postulate that the brain areas related to an interoceptive function would demonstrate an (...) intrinsic functional change after mindfulness training for the mindful novices along with paying more attention to internal processes. To further explore the influence of mindfulness on the organization of the brain regions, both functional connectivity in the voxel and the region of interest level were calculated. In the current study, 32 healthy volunteers, without any meditation experiences, were enrolled and randomly assigned to a mindfulness-based stress reduction group or control group. Participants in the MBSR group completed 8 weeks of mindfulness-based stress reduction and rated their mindfulness skills before and after MBSR. All subjects were evaluated via resting-state functional MRI in both baselines and after 8 weeks. They also completed a self-report measure of their state and trait anxiety as well as a positive and negative affect. Pre- and post-MBSR assessments revealed a decreased amplitude of low-frequency fluctuations in the right anterior cingulate gyrus, left anterior and posterior insula, as well as left superior medial frontal gyrus in MBSR practitioners. Strengthened FC between right anterior cingulate cortex and aIC.R was observed. The mean ALFF values of those regions were inversely and positively linked to newly acquired mindful abilities. Along with a decreased negative affect score, our results suggest that the brain regions related to attention and interoceptive function were involved at the beginning of mindfulness. This study provides new clues in elucidating the time of evaluating the brain mechanisms of mindfulness novices. (shrink)

This project was undertaken to ascertain the perceptions of a group of Taiwan’s fourth-year bachelor of science in nursing (BSN) students regarding death and help expected from nurses during the dying process. Within the Chinese culture, death is one of the most important life issues. However, in many Chinese societies it is difficult for people to reveal their deepest feelings to their significant others or loved ones. It was in this context that this project was developed because little is known (...) about how Taiwan’s nursing students perceive death and the dying process. Using an open-ended, self-report questionnaire, 110 senior BSN students recorded their thoughts on: (1) their fears before physical death; (2) afterlife destinations; and (3) the help they would expect from nurses when dying. The data were analyzed using a three-layer qualitative thematic analysis. The students’ reported needs during the dying process were directed towards three main goals: (1) help in reaching the ‘triple targets of individual life’; (2) help in facilitating in-depth support so that both the dying person and significant others can experience a blessed farewell; and (3) help in reaching a destination in the afterlife. The results support the belief of dying as a transition occurring when life weans itself from the mortal world and prepares for an afterlife. (shrink)

In recent years, more and more Chinese women have joined the legal profession and have made remarkable achievements in this field. Gender stereotypes, however, which involve a deep-rooted social concept, have seriously hindered Chinese women’s development in the legal profession and have had a profound and adverse impact on women’s career progression. Based on the statistical data in the public domain as well as the ethnographic data drawn from interviews with legal professionals and informal conversations with lawyers known to the (...) principal author, this paper focuses on women in the Chinese legal profession, identifies the causes of women’s dilemmas in their career development as well as the impact of gender stereotyping on them within the legal profession in order to provide some insights on improving gender equality in China. According to the authors, the causes of gender stereotypes in China are diverse: Existing legal institutions promote and maintain such stereotyping practices; traditional gender concepts enter into and disseminated in people’s thoughts; the theory of biological determinism in the field of science misleads the general public; and the legal system constructs women’s status as workers and mothers. In view of this, it is necessary to achieve substantive equality in China’s legal profession by weakening men’s domination of the legal profession, improving the structure and ideology of relevant institutions and policies in offering women more incentives for career development, and also changing women’s understanding of and efforts against biased gender stereotypes. This will help break down China’s gender stereotypes, promote gender equality in the legal profession, and address the dilemma of women’s legal career development. (shrink)

ABSTRACT The ongoing Sino-U.S. trade dispute between the world’s two largest economies has since 2018 attracted much attention from the international media. This study used the approach of corpus-assisted discourse studies to compare how leading English-language newspapers from each side—The New York Times and China Daily — discursively constructed this issue. The findings indicated that while NYT tended to profile the trade conflict as a ‘war’ in line with mainstream hard-line ideologies that emphasize China’s presumed threat to national security of (...) the U.S., CD sought to dial down the rhetoric and showed a preference for defining the matter as a ‘friction’, consistent with the tenet of ‘pragmatic nationalism’ endorsed by the Communist Party of China. Accordingly, the two newspapers framed the causes, moral evaluation/consequences, and treatment of the issue in congruence with their respective dominant metaphors by means of various linguistic patterns. These differences are interpreted with regard to each side’s underlying ideologies and national interests. (shrink)

This paper uses the Process Dissociation Procedure to explore whether people can acquire unconscious knowledge in the serial reaction time task [Destrebecqz, A., & Cleeremans, A. . Can sequence learning be implicit? New evidence with the Process Dissociation Procedure. Psychonomic Bulletin & Review, 8, 343–350; Wilkinson, L., & Shanks, D. R. . Intentional control and implicit sequence learning. Journal of Experimental Psychology: Learning, Memory, and Cognition, 30, 354–369]. Experiment 1 showed that people generated legal sequences above baseline levels under exclusion (...) instructions. Reward moved exclusion performance towards baseline, indicating that the extent of motivation in the test phase influenced the expression of unconscious knowledge. Experiments 2 and 3 revealed that even with reward, adding noise to the sequences or shortening training led to above-baseline exclusion performance, suggesting that task difficulty and the amount of training also affected the expression of unconscious knowledge. The results help resolve some current debates about the role of conscious awareness in sequence learning. (shrink)

This paper discusses Eastern European Marxists’ consideration of science and technology concerning aesthetic dimensions. Different from most of Western Marxists who take negative or dystopian attitudes towards modern science and technology from the aesthetic utopian perspective, those Marxists who come from countries such as Hungary, Yugoslav, Poland, Czechoslovakia, East Germany, Bulgaria or Romania, which once belonged to the socialist camp, under the influence of Soviet and Western culture, pay attention to the complicated tension between science-technology and aesthetics. In this paper, (...) I probe into these notions by reading György Lukács, Budapest School, Romanian theorists and the Yugoslav Praxis Group, which are divided into four key points: basic nature of science in contrast with arts; modern tension of culture between science and arts; the possibility of scientific aesthetics; and development of arts in the world of technology. There is a dialectical understanding of science and technology here which contributes to contemporary recognition of science and technology from the point of view of neo-humanism, not only in aesthetics but also human existence. This is relevant to theoretical reflection on the present and future Chinese socialist aesthetics. (shrink)

H. L. A Hart complained about the ambiguity of legal positivism, and proposed a definition that refers to particular explications of the concept of law, to certain theories of legal interpretation, to particular views on the moral problem of a duty to obey the law, and to a sceptical position with regard to the meta-ethical issue of the possibility of moral knowledge. It is said to be restricted to the Thesis of Separation — the contention that there is no necessary (...) connection between law and morals. In this chapter, the Separation Thesis is discussed even further, and has three shortcomings identified: first, that it has been vacillating between object-level contentions about moral qualities of the law; that the precise logical relation between both levels has never been properly accounted for; and that the question of necessary relations between morality and law hinges crucially on the presupposition that the very concept of law itself does not unravel into different sets of convenient stipulations from different epistemological angles, each of which renders the question of such necessary relations trivial. The Separation Thesis is also identified as having two versions: the Fallibility Law and the Neutrality Law. (shrink)

This paper offers a short history of Agnes Heller’s relationship to China through three aspects: imaginative aesthetic enjoyment, real encounters with Chinese cultural spectacles and actual audiences, and the construction of an academic community through creative dialogue. These discussions suggest that Heller felt at home in China. Although Heller has passed away, a home for us remains in her work through remembering her and engaging further with her writings.

The conceptual and methodological contributions of Marxist aesthetics from Eastern European countries like Hungary, Yugoslavia, Poland, Czechoslovakia, Bulgaria, Romania, and East Germany were productive and significant despite various hurdles faced concerning institutionalization, legitimization and differing theoretical abuses. In its mode of inquiry and discursive practices, Eastern European Marxist aesthetics is both similar and dissimilar to its Western, Soviet, Russian and Chinese counterparts. The specificity here is the function of a unique geographical and socio-historical context, as well as interaction with other (...) contemporary paradigms of thought. The innovative impulses of Eastern European Marxist aesthetics affected six scholarly domains: aesthetics of praxis, theory of realism, critique of modernity, semiotics, theory of genre and cultural theory. This paper provides a general survey of the intellectual achievements of Eastern European Marxist aesthetics across these six domains and will show how this theoretical tradition has influenced the modern history of ideas.
