    Musical Engagement and Parent-Child Attachment in Families With Young Children During the Covid-19 Pandemic.Selena Steinberg, Talia Liu & Miriam D. Lense - 2021 - Frontiers in Psychology 12.
    The onset of the Covid-19 pandemic has disrupted the lives of families in the United States and across the world, impacting parent mental health and stress, and in turn, the parent-child relationship. Music is a common parent-child activity and has been found to positively impact relationships, but little is known about music’s role in parent-child interactions during a pandemic. The current study utilized an online questionnaire to assess the use of music in the home of young children and their parents (...)

    Group ethical voice and ethical behaviors: The mediating role of group moral transitive motivation and moderating role of group faultlines.Meng Qi, Bin Feng, Fei Liu & Ting Qian - forthcoming - Business Ethics, the Environment and Responsibility.
    Ethical voice involves individuals’ perceptions of what is right and what is wrong. Although prior research has investigated the impacts of individual-level prohibitive ethical expression on personal outcomes, there has been limited examination of ethical voice at the group level. Our study examines how and when different types of ethical voice influence group outcomes. Using data gathered from 363 participants from 61 groups in two Chinese companies, the results reveal that promotive and prohibitive ethical voices at the group level exert (...)

  8. A new framework for host-pathogen interaction research.Hong Yu, Li Li, Anthony Huffman, John Beverley, Junguk Hur, Eric Merrell, Hsin-hui Huang, Yang Wang, Yingtong Liu, Edison Ong, Liang Cheng, Tao Zeng, Jingsong Zhang, Pengpai Li, Zhiping Liu, Zhigang Wang, Xiangyan Zhang, Xianwei Ye, Samuel K. Handelman, Jonathan Sexton, Kathryn Eaton, Gerry Higgins, Gilbert S. Omenn, Brian Athey, Barry Smith, Luonan Chen & Yongqun He - 2022 - Frontiers in Immunology 13.
    COVID-19 often manifests with different outcomes in different patients, highlighting the complexity of the host-pathogen interactions involved in manifestations of the disease at the molecular and cellular levels. In this paper, we propose a set of postulates and a framework for systematically understanding complex molecular host-pathogen interaction networks. Specifically, we first propose four host-pathogen interaction (HPI) postulates as the basis for understanding molecular and cellular host-pathogen interactions and their relations to disease outcomes. These four postulates cover the evolutionary dispositions involved (...)

    Specificity of face processing without awareness.Guomei Zhou, Lingxiao Zhang, Jinting Liu, Jiaoteng Yang & Zhe Qu - 2010 - Consciousness and Cognition 19 (1):408-412.
    The recognition memory for inverted faces is especially difficult when compared with that for non-face stimuli. This face inversion effect has often been used as a marker of face-specific holistic processing. However, whether face processing without awareness is still specific remains unknown. The present study addressed this issue by examining the face inversion effect with the technique of binocular rivalry. Results showed that invisible upright faces could break suppression faster than invisible inverted faces. Nevertheless, no difference was found for invisible (...)

    Nothingness in Asian Philosophy.Douglas L. Berger & JeeLoo Liu (eds.) - 2014 - New York: Routledge.
    A variety of crucial and still most relevant ideas about nothingness or emptiness have gained profound philosophical prominence in the history and development of a number of South and East Asian traditions--including in Buddhism, Daoism, Neo-Confucianism, Hinduism, Korean philosophy, and the Japanese Kyoto School. These traditions share the insight that in order to explain both the great mysteries and mundane facts about our experience, ideas of "nothingness" must play a primary role. This collection of essays brings together the work of (...)

    The Neural Mechanisms of Cognitive Control in the Category Induction Task.Xueli Cai, Guo Li, Qinxia Liu, Feng Xiao, Youxue Zhang & Yifeng Wang - 2022 - Frontiers in Psychology 13.
    According to the conflict monitoring hypothesis, conflict monitoring and inhibitory control in cognitive control mainly cause activity in the anterior cingulate cortex and control-related prefrontal cortex in many cognitive tasks. However, the role of brain regions in the default mode network in cognitive control during category induction tasks is unclear. To test the role of the ACC, PFC, and subregions of the DMN elicited by cognitive control during category induction, a modified category induction task was performed using simultaneous fMRI scanning.

    Exploring English for medical purposes (EMP) teacher cognition in the Chinese context.Zhongkai Cao, Zaihong Zhang, Ya Liu & Liping Pu - 2022 - Frontiers in Psychology 13.
    It has been a growing trend in Chinese universities to shift from English for general purposes to English for specific purposes teaching. Against this background, large groups of teachers previously engaged in teaching EGP have become or are becoming ESP teachers, which means a complex process of learning for subject-specific information, transforming teaching practices and constructing new identities. Despite this, very little has been written about the ESP teacher cognition of language teaching or the factors influencing this shift in teaching. (...)

  30. Experiencing an art education program through immersive virtual reality or iPad: Examining the mediating effects of sense of presence and extraneous cognitive load on enjoyment, attention, and retention.Qingyang Tang, Yanyun Wang, Hao Liu, Qian Liu & Shen Jiang - 2022 - Frontiers in Psychology 13.
    Sense of presence and extraneous cognitive load are the two psychological effects widely employed to explain the cognitive outcomes caused by high-immersive media. This study identified the concepts of both technological affordance and the psychological effects of VR learning. It investigated the mechanism by which immersion leads to better or worse communication in the context of art education. We operationalized the concept of immersion into two levels: a high-immersive VR system and a low-immersive tablet system. Through a between-subject experiment, we (...)

    A categorical equivalence between logical quantale modules and quantum B‐modules.Xianglong Ruan & Xiaochuan Liu - forthcoming - Mathematical Logic Quarterly.
    This paper introduces the notion of logical quantale module. It proves that there is a dual equivalence between the category of logical quantale modules and the category of quantum B‐modules, in the way that every quantum B‐module admits a natural embedding into a logical quantale module, the enveloping quantale module.

    Why Tu Youyou Makes Less Money Than Zhang Ziyi?Qinghui Suo, Yang Liu & Daming Zhang - 2017 - Science and Engineering Ethics 23 (4):1233-1235.
    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.

    The New Biopolitics.Jiangxia Yu & Jingwei Liu - 2009 - Journal of Academic Ethics 7 (4):287-296.
    The biotech revolution profoundly changes and reconstructs the Foucaultian concept of biopolitics from different dimensions. It declares the coming of the Age of Biocapitalism, which opens a new pattern of modern power allocation of life governance and shows people two prospects simultaneously: utopian hopes and dystopian desperation. Biocapitalism has not only produced ethical degeneration and cultural shock, but more importantly, has opened new areas for political hegemony and economic aggression through the reconstruction of biopolitics, and the enhancement of capital’s comprehensive (...)

    Regional impairment of deep gray matter perfusion in neonates with congenital heart disease revealed by arterial spin labeling MRI.Yan Sun, Yujie Liu, Wenwen Yu & Yumin Zhong - 2022 - Frontiers in Human Neuroscience 16:803006.
    The present study examined deep gray matter perfusion in neonates with congenital heart disease (CHD) with arterial spin labeling magnetic resonance imaging preoperatively. We found that neonates with cyanotic CHD showed lower right thalamus compared with controls and lower right basal ganglia perfusion compared with acyanotic CHD. When the CHD group was assessed as a whole, it showed slightly decreased left thalamus perfusion compared with controls. The results suggest that cardiac physiology plays a crucial part in changes in regional cerebral (...)

Wzięliśmy pod uwagę zarówno perspektywę logiczną. jak i lingwistyczną, zwracając szczególną uwagę na specyfikę klasycznego języka chińskiego, rolę kontekstu i uwzględniając wszelkie możliwe wskazówki pochodzące ze źródłowych tekstów. Poprzez zastosowania reguł monotoniczności sformułowaliśmy jednolitą odpowiedź na pytanie, dlaczego shi er ran są uznawane za rozumowania poprawne, a shi er buran przeciwnie — uznawane są za kontrprzykłady.
