The quality and quantity of training data are crucial to the performance of a deep-learning-based brain-computer interface system. However, it is not practical to record EEG data over several long calibration sessions. A promising time- and cost-efficient solution is artificial data generation or data augmentation. Here, we proposed a DA method for the motor imagery EEG signal called brain-area-recombination. For the BAR, each sample was first separated into two ones by left/right brain channels, and the artificial samples were generated by (...) recombining the half-samples. We then designed two schemas corresponding to the single- and multi-subject scenarios. Extensive experiments using the classifier of EEGnet were conducted on two public datasets under various training set sizes. In both schemas, the BAR method can make the EEGnet have a better performance of classification. To make a comparative investigation, we selected two common DA methods, and the BAR method beat them. Further, using the proposed BAR for augmentation, EEGnet achieved up to 8.3% improvement than a typical decoding algorithm CSP-SVM, note that both the models were trained on the augmented dataset. This study shows that BAR usage can significantly improve the classification ability of deep learning to MI-EEG signals. To a certain extent, it may promote the development of deep learning technology in the field of BCI. (shrink)

Authoritarian leadership is of great significance to eastern countries, including China. Meanwhile, unethical employee behavior also exists in all types of social organizations. The relationship between authoritarian leadership and unethical employee behavior is worth studying. Senior leaders often do not have a direct influence on employees except for through their immediate supervisors. The leadership style of senior leaders also influences the leadership style of their subordinates. This paper studies how authoritarian manager leadership trickles down to unethical employee behavior through authoritarian (...) supervisor leadership and discusses the moderating effect of leader member exchange and an ethical climate. Through a questionnaire survey of 406 pairs of leaders, supervisors, and employees, the research results of the multilevel model show that authoritarian supervisor leadership is positively related to unethical employee behavior, authoritarian supervisor leadership mediates the relationship between authoritarian manager leadership and unethical employee behavior, LMX positively moderates the relationship between authoritarian manager leadership and authoritarian supervisor leadership and moderates the mediating effect of authoritarian supervisor leadership, and, that an ethical climate negatively moderates the relationship between authoritarian supervisor leadership and unethical employee behavior and moderates the mediating effect of authoritarian supervisor leadership.

Resumo: O pós-modernismo ocidental é uma tendência cultural de pensamento que surgiu nas décadas de 1960 e 1970. Sua influência envolve muitos campos, como arte, literatura, filosofia e estética, o que indica que uma grande mudança ocorreu em toda a sociedade ocidental e também tem um impacto profundo na cultura e na arte contemporâneas. Ao analisar a influência de longo alcance do pós-modernismo, na música e na filosofia, este artigo fornece estratégias de desenvolvimento e sugestões para a música e a (...) filosofia, sob o pano de fundo do pós-modernismo. Este texto estudou os efeitos positivos e negativos do pós-modernismo na filosofia e na música, sob dois aspectos: música e filosofia. A influência positiva do pós-modernismo na filosofia e na música manifesta-se na defesa da igualdade, da harmonia entre o homem e a natureza, da inovação e do espírito crítico. É claro que a tendência de pensamento do pós-modernismo também tem alguns efeitos negativos, os quais devem ser vistos dialeticamente, em seu impacto sobre a música e a filosofia. Com a premissa de incentivar a inovação, respeitar a liberdade e a diferença, deve-se estabelecer uma autoconfiança de valor, de modo a promover o desenvolvimento da filosofia e da música. O pós-modernismo é uma forma cultural do período posterior do capitalismo. No campo da música, é necessário não apenas aderir à rebeldia e à abertura trazidas pelo pós-modernismo, mas também dar importância ao valor artístico das obras musicais para evitar a produção e a proliferação de obras musicais vulgarizadas. A influência do pós-modernismo na música e na filosofia, que estudamos neste artigo, tem um significado prático importante. (shrink)

Objectives Older adults are considered one of the most vulnerable groups to COVID-19. However, previous studies on emotion and aging have found that older adults report better well-being than younger adults in global survey and daily report. To better understand older adults’ well-being during the COVID-19 outbreak, we examined age differences in daily affective experiences in this study. Method Two hundred and thirty-one participants from mainland China aged 18 to 85 were recruited to participate in the 14-day daily diary study, (...) after a pretest. Their trait affect and demographic information were measured in the pretest. Their daily affect and stress levels were measured in the daily assessments. Results We found that older adults reported lower perceived stress related to COVID-19 in daily life, compared to younger adults. The negative relationship between daily perceived stress and high arousal positive affect and the positive relationship between daily perceived stress and high arousal negative affect was weaker in older than younger adults. Discussion These results provide initial evidence of daily affective well-being across different age groups in adulthood during the COVID-19 outbreak. Such information is important for developing interventions to promote better well-being during the COVID-19 outbreak. (shrink)

DNA replication stress threatens ordinary DNA synthesis. The evolutionarily conserved DNA replication stress response pathway involves sensor kinase Mec1/ATR, adaptor protein Mrc1/Claspin, and effector kinase Rad53/Chk1, which spurs a host of changes to stabilize replication forks and maintain genome integrity. DNA replication forks consist of largely distinct sets of proteins at leading and lagging strands that function autonomously in DNA synthesis in vitro. In this article, we discuss eSPAN and BrdU‐IP‐ssSeq, strand‐specific sequencing technologies that permit analysis of protein localization and (...) DNA synthesis at individual strands in budding yeast. Using these approaches, we show that under replication stress Rad53 stalls DNA synthesis on both leading and lagging strands. On lagging strands, it stimulates PCNA unloading, and on leading strands, it attenuates the replication function of Mrc1‐Tof1. We propose that in doing so, Rad53 couples leading and lagging strand DNA synthesis during replication stress, thereby preventing the emergence of harmful ssDNA. (shrink)

ABSTRACT This study investigated what information about brain death was available from Google searches for five major religions. A substantial body of supporting research examining online behaviors shows that information seekers use Google as their preferred search engine and usually limit their search to entries on the first page. For each of the five religions in this study, Google listings reveal ethical controversy about organ donation in the context of brain death. These results suggest that family members who go online (...) to find information about organ donation in the context of brain death would find information about ethical controversy in the first page of Google listings. Organ procurement agencies claim that all major world religions approve of organ donation and do not address the ethical controversy about organ donation in the context of brain death that is readily available online.

This essay is an attempt to sketch out two contrasting notions of freedom in the Zhuangzi and the Xunzi . I argue that to understand the classical Chinese formulations of freedom we should look at the concept of hua 化 (transformation or to transform). It is a kind of freedom that highlights the moral and/or spiritual transformation of the self and its entailments on the connection between the self and various domains of relationality. The Zhuangzian hua is the transformation of (...) the self in such a way that the self becomes supremely attuned to the complexity of the world and can thus navigate various domains of relationality with extraordinary grace, ease, and efficacy. The Xunzian hua is the transformation of the self so that the self can extend its relationality to include the entire world and transform it from a raw and uncouth world to a civilized one through ritual practices.
