The human brain shows neuroplastic adaptations induced by motor skill training. However, the description of the plastic architecture of the whole-brain network in resting-state is still limited. In the present study, we aimed to detect how motor training affected the density distribution of whole-brain resting-state functional connectivity (FC) brain in fast-ball student-athletes using resting-state functional magnetic resonance imaging (fMRI) data of student-athletes (SA), and non-athlete healthy controls (NC). The voxel-wise data-driven graph theory approach, namely global functional connectivity density (gFCD) mapping (...) was applied. The results showed that the SA group exhibited significantly decreased gFCD in brain regions centered at left triangular part of inferior frontal gyrus (IFG), extending to opercular part of left IFG and middle frontal gyrus (MFG) compared with NC group. The findings supported the idea of an increased neural efficiency of athletes’ brain in the brain regions associated with attentional-motor modulation and executive control. Furthermore, the behavioral results demonstrated that in the SA group, faster executive control reaction time was associated with smaller gFCD values in left IFG. The findings implied that the motor skill training would decrease the numbers of FC in IFG to accelerate the execution control with high attentional demands, and focus the attention to the target detection the athletes are interested in.

ObjectiveThis study aimed to develop a diagnostic model of multi-kinematic parameters for patients with amnestic mild cognitive impairment (aMCI).MethodIn this cross-sectional study, 94 older adults were included (33 cognitively normal, CN; and 61 aMCI). We conducted neuropsychological battery tests, such as global cognition and cognitive domains, and collected gait parameters by an inertial-sensor gait analysis system. Multivariable regression models were used to identify the potential diagnostic variables for aMCI. Receiver operating characteristic (ROC) curves were applied to assess the diagnostic accuracy (...) of kinematic parameters in discriminating aMCI from healthy subjects.ResultsMultivariable regression showed that multi-kinematic parameters were the potential diagnostic variables for aMCI. The multi-kinematic parameter model, developed using Timed Up and Go (TUG) time, stride length, toe-off/heel stride angles, one-leg standing (OLS) time, and braking force, showed areas under ROC (AUC), 0.96 [95% confidence interval (CI), 0.905–0.857]; sensitivity, 0.90; and specificity, 0.91. In contrast, a single kinematic parameter’s sensitivity was 0.26–0.95 and specificity was 0.21–0.90. Notably, the separating capacity of multi-kinematic parameters was highly similar to Montreal Cognitive Assessment (MoCA; AUC: 0.96 vs. 0.95). Compared to cognitive domain tests, the separating ability was comparable to Auditory Verbal Learning Test (AVLT) and Boston Naming Test (BNT; AUC: 0.96 vs. 0.97; AUC: 0.96 vs. 0.94).ConclusionWe developed one diagnostic model of multi-kinematic parameters for patients with aMCI in Foshan.

This study examined how self-worth of students mediated and moderated their perceived positive teacher-student relationships and student engagement among middle-school students from rural China. Eighth graders completed surveys measuring their perceived relationships with teachers, their self-worth, and engagement. Statistical analyses revealed significant correlations among all three variables, with the strongest being between teacher-student relationships and student engagement. The structural equation modeling indicated that self-worth partially mediated the effect of teacher-student relationships on student engagement; however, positive teacher-student relationships were a stronger (...) predictor. Multigroup analyses identified self-worth as a moderator, whereby students with lower self-worth were more reliant on positive teacher-student relationships to enhance their engagement. This study provides insights into how self-worth of students and their perceived positive teacher-student relationships influence their academic engagement in disadvantaged rural areas of China.

Objective: Automatic detection of auditory stimuli, represented by the mismatch negativity, facilitates rapid processing of salient stimuli in the environment. The amplitude of MMN declines with ageing. However, whether automatic detection of auditory stimuli is affected by visually perceived negative emotions with normal ageing remains unclear. We aimed to evaluate how fearful facial expressions affect the MMN amplitude under ageing.Methods: We used a modified oddball paradigm to analyze the amplitude of N100 and MMN in 22 young adults and 21 middle-aged (...) adults.Results: We found that the amplitude of N1 elicited by standard tones was smaller under fearful facial expressions than neutral facial expressions and was more negative for young adults than middle-aged adults. The MMN amplitude under fearful facial expressions was greater than neutral facial expressions, but the amplitude in middle-aged adults was smaller than in young adults.Conclusion: Visually perceived negative emotion promotes the extraction of auditory features. Additionally, it enhances the effect of auditory change detection in middle-aged adults but fails to compensate for this decline with normal ageing.Significance: The study may help to understand how visually perceived emotion affects the early stage of auditory information processing from an event process perspective.

In a recent article in this journal, Calemi challenges the Küng-Armstrong trilemma, a well-known objection to traditional class nominalism, by proposing a fusion of class nominalism with Zermelo-Fraenkel set theory (ZF). In this note, we argue that ZF-class nominalism faces significant challenges in the form of incompleteness and potential paradoxes stemming from Gödel’s incompleteness theorem. We will explore these issues in detail, highlighting the key implications for the viability of ZF-class nominalism as a philosophical position.

In _Shifts of Power: Modern Chinese Thought and Society_, Luo Zhitian explores the causes and consequences of various shifts of power during the transition from imperial to Republican China.

In the formal semantics based on modern type theories, common nouns are interpreted as types, rather than as predicates of entities as in Montague’s semantics. This brings about important advantages in linguistic interpretations but also leads to a limitation of expressive power because there are fewer operations on types as compared with those on predicates. The theory of coercive subtyping adequately extends the modern type theories and, as shown in this paper, plays a very useful role in making type theories (...) more expressive for formal semantics. It not only gives a satisfactory solution to the basic problem of ‘multiple categorisation’ caused by interpreting common nouns as types, but provides a powerful formal framework to model interesting linguistic phenomena such as copredication, whose formal treatment has been found difficult in a Montagovian setting. In particular, we show how to formally introduce dot-types in a type theory with coercive subtyping and study some type-theoretic constructs that provide useful representational tools for reference transfers and multiple word meanings in formal lexical semantics.

This essay breaks new ground in defending the view that contemporary care-based ethics and early Confucian ethics share some important common ground. Luo also introduces the notion of relational virtue in an attempt to bridge a conceptual gap between relational caring ethics and agent-based virtue ethics, and to make the connections between the ethics of care and Confucian ethics philosophically clearer and more defensible.

This essay examines the classical Confucian perspective on the topic of happiness through the lens of three Western theories: hedonism, desire satisfaction theory, and objective list theory. My analysis of the two classical texts—the Analects and the Mencius —reveals that three salient aspects of the Confucian conception of happiness, namely ethical pleasure, ethical desire, and moral innocence, play the fundamental role in the guidance and evaluation of an individual’s life. According to Confucius and Mencius, happiness consists primarily not in pleasure, (...) but in ethical pleasure; the good life is not a life in which all or most of one’s desires are fulfilled, but a life in which the satisfaction of prudential desires is subject to the constraint of ethical desire; the source of the greatest happiness lies not in the attainment of the greatest political power, but rather in the cognizance of one’s moral innocence. For classical Confucian thinkers, the relationship between happiness and the good life is that happiness is a critically important constituent of the good life. However, happiness—defined in terms of pleasure, desire satisfaction, or a list of goods—needs to be tempered by moral constraints. In light of their views on happiness and the good life, I conclude that Confucius and Mencius each lived a good life that exemplified the three salient features of happiness, and to that extent they were happy.

In recent years, the translation of Debray’s writings and the study of his media thoughts have become increasingly popular in China, but the ‘medium’ in his media discourse has never been clarified. Debray pointed out that the focus of the media is ‘mediation’, which actually reveals a new way of thinking and reasoning. He then proposed four stages of mediological reasoning: Message, Medium, Milieu and Mediation. This article believes that based on this framework (i.e. 4M), Debray used McLuhan’s theory as (...) a hub for analysis and launched a set of research methods and tools aimed at exploring the multiple nature of medium and message on the sense of interaction between culture and technology, which also involved the utility of ‘mediasphere’ as an exploration principle to question the past and future of mankind and the media conditions. This approach provides an avenue for us to understand ourselves and transmissions in different space-time categories at both practical and theoretical levels. This article emphasizes that it is better not to interpret Debray’s thoughts as a theory parallel to the existing medium theories because its focus is on research approaches rather than arguments. Besides, although Debray’s medium theory is based on his experience and thinking in Europe and Latin America, there are reasons for the publicity of Debray’s ideology in China. From the perspective of history, culture and human geography, Chinese civilization can be said to contain rich ideological resources of mediation. This is of great significance to re-understand China’s history and reality in the new context of globalization, and to discover the global value of China’s experience. (shrink)

Given that women CEOs are usually more risk averse, engage less in opportunistic behavior, and provide higher quality earnings than men CEOs, we argue that firms with women CEOs are likely to face lower operational and information risk and thus enjoy cheaper external funds. Using a large sample of Chinese A-share listed firms operating from 2006 to 2012, we find consistent evidence that Chinese banks tend to impose lower loan costs on firms with women CEOs compared to firms with men (...) CEOs. This effect is more pronounced for non-state-owned enterprises than for state-owned enterprises, for firms without political connections than for firms with political connections, and during non-crisis periods. We do not find any significant effects for firms with women chairpersons, CFOs, or directors. (shrink)

Hierarchies occur widely in evolving self‐organizing ecological, biological, technological, and social networks, but detecting and comparing hierarchies is difficult. Here we present a metric and technique to quantitatively assess the extent to which self‐organizing directed networks exhibit a flow hierarchy. Flow hierarchy is a commonly observed but theoretically overlooked form of hierarchy in networks. We show that the ecological, neurobiological, economic, and information processing networks are generally more hierarchical than their comparable random networks. We further discovered that hierarchy degree has (...) increased over the course of the evolution of Linux kernels. Taken together, our results suggest that hierarchy is a central organizing feature of real‐world evolving networks, and the measurement of hierarchy opens the way to understand the structural regimes and evolutionary patterns of self‐organizing networks. Our measurement technique makes it possible to objectively compare hierarchies of different networks and of different evolutionary stages of a single network, and compare evolving patterns of different networks. It can be applied to various complex systems, which can be represented as directed networks. (shrink)

In recent years, the phenomenological approach to empathy becomes increasingly influential in explaining social perception of other people. Yet, it leaves untouched a related and pivotal question concerning the unique and irreducible intentionality of empathy that constitutes the peculiarity of social perception. In this article, I focus on this problem by drawing upon Husserl’s theory of image-consciousness, and I suggest that empathy is characterized by a “seeing-in” structure. I develop two theses so as to further explicate the seeing-in structure in (...) question: first, empathy as a phenomenologically sui generis act is an intentional fusion of both presentation and re-presentation; and second, empathic intentionality is in essence twofold in that it is at once directed at both the other’s sensuously given body and the other’s non-sensuously given mentality. In this light, I argue that empathy is better conceived as a quasi-perceptual act that is fundamentally different from external perception simpliciter and other complex acts such as signitive, recollective and imaginative intention.

In this paper I scrutinize the “rational beliefs” in the concept of rationalizability in strategic games [Bernheim, Pearce ]. I illustrate through an example that a rationalizable strategy may not be supported by a “rational belief”, at least under one plausible interpretation of “rational belief”. I offer an alternative formulation of “rational belief” in the concept of rationalizability, which yields a novel epistemic interpretation of the notion of point-rationalizability.

This essay calls attention to an aspect of Confucius's notion of ren that has often been overlooked or even denied in much recent discussion of the topic. While the egalitarian aspect of ren, i.e., the idea that every human being has the potential to become a ren person, is frequently asserted, the leadership dimension of ren has for the most part been given short shrift. I argue that for Confucius, ren is the leadership virtue. This conclusion is mainly based on (...) a careful and systematic analysis of what may be called ?the definitional ren passages? and some ?elucidative ren passages? in the Analects. (shrink)
