BackgroundExercise is one of the effective ways to improve cognition. Different forms of exercises, such as aerobic exercise, resistance exercise, and coordination exercise, have different effects on the improvement of cognitive impairment. In recent years, exergames based on Non-Immersive Virtual Reality have been widely used in entertainment and have gradually been applied to clinical rehabilitation. However, the mechanism of NIVR-Exergames on improving motor cognition has not been clarified. Therefore, the aim of this study is to find whether NIVR-Exergames result in (...) a better neural response mechanism to improve the area of the cerebral cortex related to motor cognition under functional near-infrared spectroscopy dynamic monitoring in comparison with resistance exercise.MethodsA cross-over study design was adopted in this study, and 15 healthy young subjects were randomly divided into group A and group B according to a computerized digital table method. Task 1 was an NIVR-Exergame task, and Task 2 was resistance band stretching. Group A first performed Task 1, rested for 30 min, and then performed Task 2. Group B had the reverse order. The fNIRS test was synchronized in real time during exercise tasks, and heart rate measurements, blood pressure measurements, and 2-back task synchronization fNIRS tests were performed at baseline, Post-task 1, and Post-task 2. The primary outcomes were beta values from the general linear model in different regions of interest, and the secondary outcomes were heart rate, blood pressure, reaction time of 2-back, and accuracy rate of 2-back.ResultsThe activation differences of Task 1 and Task 2 in the right premotor cortex and the left PMC were statistically significant. There were statistically significant differences in the activation of the right supplementary motor area, left dorsolateral prefrontal cortex, left and right PMC between baseline and Post-task 1. The differences in systolic pressure between the two groups at three time points among women were statistically significant.ConclusionIn this study, we found that NIVR-Exergames combined with motor and challenging cognitive tasks can promote the activation of SMA, PMC and DLPFC in healthy young people compared with resistance exercise alone, providing compelling preliminary evidence of the power for the rehabilitation of motor and cognitive function in patients with central nervous system diseases.

According to the received account of guilt in the philosophical literature, one cannot feel guilt unless one takes oneself to have done something morally wrong. But ordinary people feel guilt in many cases in which they do not take themselves to have done anything morally wrong. In this paper, I focus on one kind of guilt without perceived wrongdoing, guilt about being merely causally responsible for a bad state-of-affairs. I go on to present a novel account of guilt that explains (...) guilt about mere causal responsibility, according to which guilt represents part of the self as bound up with what is bad. (shrink)

Call "radical moral theorizing" the project of developing a moral theory that not only tries to conform to our existing moral intuitions, but also manifests various theoretical virtues: consistency, simplicity, explanatory depth, and so on. Many moral philosophers assume that radical moral theorizing does not require any particular metaethical commitments. In this paper, I argue against this assumption. The most natural justification for radical moral theorizing presupposes moral realism, broadly construed; in contrast, there may be no justification for radical moral (...) theorizing if moral anti-realism is true.

According to the safety principle, if one knows that p, one's belief that p could not easily have been false. One problem besetting this principle is the lottery problem – that of explaining why one does not seem to know that one will lose the lottery purely based on probabilistic considerations, prior to the announcement of the lottery result. As Greco points out, it is difficult for a safety theorist to solve this problem, without paying a heavy price. In this (...) paper, I first reject three existing safety-based solutions to the lottery problem, due to Pritchard, Sosa, and Broncano-Berrocal. Failure of these accounts reveals that there is something crucial missing in the safety principle. By way of remedying this, I propose to integrate a safety principle with a condition regarding one's own awareness of (nearby) error-possibilities. The resulting account, as I argue, enjoys a number of theoretical advantages, including its capacity to handle the lottery problem. (shrink)

It is a commonplace in economics that we should disregard sunk costs. The sunk cost effect might be widespread, goes the conventional wisdom, but we would be better off if we could rid ourselves of it. In this paper, I argue against the orthodoxy by showing that the sunk cost effect is often beneficial. Drawing on discussions of related topics in dynamic choice theory, I show that, in a range of cases, being disposed to honor sunk costs allows an agent (...) to mimic a resolute chooser, someone who adopts the best plan at the outset of a decision problem and sticks with it, even when resoluteness is unfeasible. I discuss several kinds of cases in which honoring sunk costs coincides with resolute choice. (shrink)

Sensitivity account of knowledge states that if one knows that _p_ (via method M), then were _p_ false, one would not believe that _p_ via M. This account has been highly controversial. However, even its critics tend to agree that the account enjoys an important advantage of solving the Gettier problem—that is, it explains why Gettierized beliefs are not knowledge. In this paper, I argue that this purported advantage of sensitivity is merely illusory. The account cannot, in principle, solve the (...) Gettier problem. Moreover, another formulation of sensitivity—which is fully in line with Nozick’s original account—is not unscathed either. (shrink)

With the continuous development of society, the role of the visual guidance system in animation design has also evolved and evolved in its long history, leading to the changes in the values of modern beauty. In the field of modern social and cultural design, the visual guidance system in animation design has unique regional nature and cultural influence. The visual language should correspond to the visual environment and easy to understand and be known by people. It combines animation conception and (...) design technology to capture the cultural charm and beauty, values, and behavioral norms of people in different fields. This article studies and analyzes the visual orientation of graphic language in the design of animation visual guidance system, and injects the graphic language with orientation into its animation design, so that the animation design is more in line with the characteristics of the times. It can be more adapted to the emerging media and better convey the information transfer between the enterprise and the audience. To further understand the audience’s tendency toward elements of graphic expression, this article analyzes the subjective perceptions of the respondents on the importance of color selection, calligraphy fonts, graphic expression, and modeling meaning. The results of the study showed that the respondents aged 21–35 paid more attention to the choice of graphic colors, and the highest number was 69. (shrink)

This paper examines the role existence plays in measurement validity. I argue that existing popular theories of measurement and of validity follow a correspondence framework, which starts by assuming that an entity exists in the real world with certain properties that allow it to be measurable. Drawing on literature from the sociology of measurement, I show that the correspondence framework faces several theoretical and practical challenges. I suggested the validity-first framework of measurement, which starts with a practice-based validation process as (...) the basis for a measurement theory, and only posits objective existence when it is scientifically useful to do so.

One interesting and potentially attractive feature of the sensitivity account of knowledge is that it not only preserves knowledge of ordinary propositions, but also concedes the skeptic's intuition that we do not know skeptical hypotheses do not obtain. This paper challenges the sensitivity‐based reply to the skeptic, advocated by Robert Nozick, among others. Sensitivity generates an implausibly bizarre result that although we do not know we are not brains in vats (because a belief to this effect is insensitive), a real (...) BIV who is in a much worse epistemic situation can sensitively believe that it is not in the good case. This result reveals a fundamental problem with the sensitivity conditional: its antecedent is not suitable for picking out possibilities that are relevant for our epistemic evaluation. I then offer a systematic explanation of why it is the safety account—the main competitor of sensitivity—that picks out a more suitable set of possibilities. A consequence of this comparison is that the safety account delivers an overall more satisfying reply to the skeptic than sensitivity does. (shrink)

Seepage analysis is always a concern in dam safety and stability research. The prediction and analysis of seepage pressure monitoring data is an effective way to ensure the safety and stability of dam seepage. With the timeliness of a change in a monitoring value and lag due to external influences, a RS-LSTM model written in Python is developed in this paper which combines rough set theory and the long- and short-term memory network model. The model proposed calculates the prediction score (...) of the seepage pressure of a dam experiencing multiple effects by preordering factor importance values to eliminate the interference of redundant factors. A case study shows that the water level, rainfall, temperature, and duration are all factors that affect the seepage pressure, and their importance values decrease successively. Thus, the seepage pressure of a dam can be predicted with a determination coefficient R2 of 0.96. Compared with the recurrent neural network model and BP neural network model, the training time of the RS-LSTM model proposed is 6.37 s, and the operation efficiency is 41% and 59% higher than that of the RNN and BP models, respectively. The mean relative error is also 3.00%, which is 50% lower than that of the RNN model and 31% lower than that of the BP model. Based on these results, this model has the advantages of fast computation speed and high accuracy in prediction. (shrink)

Two essential components make up the semantic information that was used to pinpoint the video events. They consist of: (a) A spatial component of a video frame, such as the scenery, visible people, and visible objects. (b) A temporal component that is represented by a series of video frames across time, such as the actions of a character or the movements of an object. The video's audio, video, and text components are examined in order to provide the higher-level semantic data. (...) The semantic structure of the movie is discovered using a variety of cues from many modalities, such as auditory and visual elements, bridging the gap between high level semantic notions and low level qualities. A video contains three distinct modalities. The three are as follows: (1) Visual modality, which refers to the scene seen in the video; (2) Auditory modality, which refers to spoken words, background music, and other noises; and (3) Textual modality, which refers to written materials that describe the subject matter of the movie. There are numerous video databases and a sizable amount of video data in general. Even while there are tools for maintaining and exploring these collections, many decision-making applications increasingly require tools to extract the critical information hidden in the video data.

According to the sensitivity account of knowledge, if one knows that p, then (roughly) were p false, one would not believe that p. One important issue regarding sensitivity is whether or not it preserves inductive knowledge. Critics including Jonathan Vogel, Ernest Sosa, and Duncan Pritchard argue that it does not. Proponents including Kevin Wallbridge insist that it does. In this paper, I first draw attention to an often-neglected distinction between two different versions of sensitivity—a distinction that has important implications for (...) the debate regarding inductive knowledge. In particular, I distinguish between the sensitivity principle originally defended by Robert Nozick and another version that has been the focus of many recent discussions. With the distinction in place, it is shown that a sensitivity theorist cannot preserve inductive knowledge while being unscathed. For neither account can simultaneously preserve inductive knowledge while properly handling the Gettier problem. Overall, sensitivity theorists are in trouble. (shrink)

This speculative paper enquires into the discourse of the ‘end of labour’ or ‘disappearance of labour’ as a result of the development of ‘intelligent capitalism’ clearly seen in ‘intelligent manufacturing’ systems that are now pursued and developed as Industry 4.0 strategy in East Asia, Germany and others parts of the world. When ‘intelligent capitalism’ becomes the norm rather the exception what happens to labour as a factor of production and what happens to economy and society based on capital and labour? (...) The paper briefly reviews the sociology of labour from a Marxist view to examine conceptions of Fordist and post-Fordist capitalism, and explore the advert of ‘intelligent capitalism’ to pose the question concerning education.

Statistical distributions play a prominent role for modeling data in applied fields, particularly in actuarial, financial sciences, and risk management fields. Among the statistical distributions, the heavy-tailed distributions have proven the best choice to use for modeling heavy-tailed financial data. The actuaries are often in search of such types of distributions to provide the best description of the actuarial and financial data. This study presents a new power transformation to introduce a new family of heavy-tailed distributions useful for modeling heavy-tailed (...) financial data. A submodel, namely, heavy-tailed beta-power transformed Weibull model is considered to demonstrate the adequacy of the proposed method. Some actuarial measures such as value at risk, tail value at risk, tail variance, and tail variance premium are calculated. A brief simulation study based on these measures is provided. Finally, an application to the insurance loss dataset is analyzed, which revealed that the proposed distribution is a superior model among the competitors and could potentially be very adequate in describing and modeling actuarial and financial data.

Dialogue between eastern and western philosophies -- Dialogue between Confucianism and Christianity.

Since the beginning of the twentieth century, Chinese scholars have tended to traditional Chinese learning split apart and rearrange it according to the systematics of modern Western academic disciplines. By examining the meaning of Western "philosophy" and "ethics," it is demonstrated that Western and Chinese learning should not be lumped together according to the same systematics. Moreover, classical Chinese learning has always had its own complex systematics and its own long tradition, and it has undergone constant development over time. Thus, (...) it is well beyond any criticism that may be leveled at it from the standpoint of Western systematics. Even so, modern Chinese intellectuals have become accustomed to understanding classical Chinese learning through a Western prism. (shrink)

Nozick has an account of inferential knowledge which has rarely been discussed. According to this account, in order to know q via competent inference from p, S’s belief in q should track the truth of p in the right way. In detail, S knows via competent inference from p that q iff 1*. S knows that p. 2*. q is true, and S infers q from p. 3*. If q were false, S wouldn’t believe that p. 4*. If q were (...) true, S would believe that p. In this paper, it is argued that the account is problematic. It is both too restrictive and too inclusive. It is too restrictive because condition 4* is not satisfied in some cases of inferential knowledge. It is too inclusive because condition 3*, together with other conditions, could be easily satisfied in some cases where inferential knowledge does not exist. (shrink)

According to the safety account of knowledge, one knows that p only if one’s belief in p could not easily have been false. In the literature, most objections to the safety account rely on intuition of knowledge that could be easily denied by the safety theorists. In this paper, an objection to the safety account which does not make use of such intuition is raised. It is argued that either there are instances of unsafe knowledge or the safety account has (...) an implausible implication that one’s epistemic status might depend on what happens in the future.

The US and China have both benefited greatly from their trading relationship. However, motivated by a US concern that their partner was becoming more of a rival, then-president Donald Trump began a ‘trade war’ in 2018. In US news outlets and, of particular interest here, on American social media platforms, China was represented as a global menace, with extreme xenophobia against Chinese people. Yet less is known about how Chinese people responded on social media to the same situation. This paper (...) explores the discourses carried on the Chinese social media platform Weibo, focusing on the 2021 Alaska talks between the US and China, where negotiations took place. As with their US counterparts, Weibo users comment little on actual trade benefits or damages caused by the conflict. We find a strong sense of nationalism, but this is not based on xenophobia; rather on a discourse comparing the talks to similar events early in the twentieth century, where the ‘Century of Humiliation’ began, and where territories such as Hong Kong, Taiwan and Shaoshan were taken by colonial powers. Foregrounded is China’s ability now to end this humiliation. (shrink)

This paper focuses on modeling and control of a class of serial variable stiffness actuators based on level mechanisms for robotic applications. A multi-input multi-output complex nonlinear dynamic model is derived to fully describe SVSAs and the relative degree of the model is determined accordingly. Due to nonlinearity, high coupling, and parametric uncertainty of SVSAs, a neural network-based adaptive control strategy based on feedback linearization is proposed to handle system uncertainties. The feasibility of the proposed approach for position and stiffness (...) tracking of SVSAs is verified by simulation results. (shrink)

This article introduces the problem of inexistence to studies in genre and gender, providing a hermeneutic point of reference for literary history and trans theory. It seeks to negotiate the affinities and disaffinities between queer and trans by foregrounding the latter’s struggle for existence against the former’s mobilization of a rhetoric of negative relationality, while at the same time preserving the bonds of intimacy across and beyond the coalition of LGBTQIA+. Such queer intimacy is read in relation to a haptic (...) technology of queer close reading, enabling differentially sexed bodies to imaginatively inhabit each other. I begin by considering how Djuna Barnes’s close, haptic readings of Henry James and Marcel Proust enact a reversal of sex, but I consider how the affective evidence of these trans moments do not amount to trans existence but raise the ethical necessity of holding open the difference between the ephemeral trans experiences within cis existence and the real struggle for trans existence of trans subjects today. Such a divide, however, is simultaneously held against the moments of intimacy that are capable of being produced across cis and trans subjects through such close reading and cross-inhabitation of bodies. To read trans literary history before trans, I thus propose the notion of trans inexistence through an interpretation of Jacques Maritain’s figure of the “angel” and Hegel’s “beautiful soul.” By situating Barnes’s and Jean Genet’s own characterizations of their transfeminine characters in terms of the angel in a post-Romantic, Catholic context, I interpret the trans angel as a figure of inexistence, tied to a minimal transcendence from the terms of history and materiality, including the sexed body. Finally, I consider how Genet’s phenomenology of proprioception draws together the problems of queer intimacy, haptic reading, and trans inexistence. In analyzing how Genet and his characters cross-inhabit each other’s bodies via proprioceptive mimicry, I unfold both the vast potential and the limits of the intimacies constructed across cis male and transfeminine lives and the accompanying role played by the literary mode of romance.
