Understanding a proposition for an intelligent agent is an important epistemic concept. We first discuss intuitively general logic characteristics of understanding, and give a language and a semantics containing understanding as a modal operator. Secondly, we develop the system LU for the operator, give some results of its proof theory, and then we prove the frame soundness and frame completeness of LU.

ObjectiveVirtual reality grasping exercise training helps patients participate actively in their recovery and is a critical approach to the rehabilitation of hand dysfunction. This study aimed to explore the effects of active participation and VR grasping on brain function combined with the kinematic information obtained during VR exercises.MethodsThe cerebral oxygenation signals of the prefrontal cortex, the motor cortex, and the occipital cortex were measured by functional near-infrared spectroscopy in 18 young people during the resting state, grasping movements, and VR grasping (...) movements. The EPPlus plug-in was used to collect the hand motion data during simulated interactive grasping. The wavelet amplitude of each cerebral cortex and the wavelet phase coherence of each pair of channels were calculated by wavelet analysis. The total difference in acceleration difference of the hand in the VR grasping movements was calculated to acquire kinematic characteristics. The cortical activation and brain functional connectivity of each brain region were compared and analyzed, and a significant correlation was found between VR grasping movements and brain region activation.ResultsCompared with the resting state, the WA values of LPFC, RPFC, LMC, RMC, and ROC increased during the grasping movements and the VR grasping movements, these changes were significant in LPFC and LMC. The WA values of LMC in the VR grasping movements were significantly higher than those in the grasping movements. The WPCO of the cerebral cortex increased during grasping exercise compared with the resting state. Nevertheless, the number of significant functional connections during VR grasping decreased significantly, and only the WPCO strength between the LPFC and LMC was enhanced. The increased WA of the LPFC, RPFC, LMC, and RMC during VR grasping movements compared with the resting state showed a significant negative correlation with KCs.ConclusionThe VR grasping movements can improve the activation and FC intensity of the ipsilateral brain region, inhibit the FC of the contralateral brain region, and reduce the quantity of brain resources allocated to the task. Thus, ordered grasping exercises can enhance active participation in rehabilitation and help to improve brain function. (shrink)

Motor imagery-based brain-computer interfaces have been studied without controlling subjects’ gaze fixation position previously. The effect of gaze fixation and covert attention on the behavioral performance of BCI is still unknown. This study designed a gaze fixation controlled experiment. Subjects were required to conduct a secondary task of gaze fixation when performing the primary task of motor imagination. Subjects’ performance was analyzed according to the relationship between motor imagery target and the gaze fixation position, resulting in three BCI control conditions, (...) i.e., congruent, incongruent, and center cross trials. A group of fourteen subjects was recruited. The average group performances of three different conditions did not show statistically significant differences in terms of BCI control accuracy, feedback duration, and trajectory length. Further analysis of gaze shift response time revealed a significantly shorter response time for congruent trials compared to incongruent trials. Meanwhile, the parietal occipital cortex also showed active neural activities for congruent and incongruent trials, and this was revealed by a contrast analysis of R-square values and lateralization index. However, the lateralization index computed from the parietal and occipital areas was not correlated with the BCI behavioral performance. Subjects’ BCI behavioral performance was not affected by the position of gaze fixation and covert attention. This indicated that motor imagery-based BCI could be used freely in robotic arm control without sacrificing performance. (shrink)

BackgroundPsychological resilience may reduce the impact of psychological distress to some extent. We aimed to investigate the mental health status of the public during the outbreak of coronavirus disease 2019 and explore the level and related factors of anxiety and depression.MethodsFrom February 8 to March 9, 2020, 3,180 public completed the Zung’s Self-Rating Anxiety Scale for anxiety, Zung’s Self-Rating Depression Scale for depression, the Connor–Davidson resilience scale for psychological resilience, and the Simplified Coping Style Questionnaire for the attitudes and coping (...) styles.ResultsThe number of people with depressive symptoms was 1,303. The number of people with anxiety symptoms was 1,184. The depressed group and anxiety group had less education, more unmarried and younger age, as well as had significant different in SDS total score, SAS total score, CD-RISC total score, and SCSQ score. The binary logistic regression showed that female, strength, and the subscales of active coping style in SCSQ remained protective factors and passive coping style and higher SAS score were risk factors for depression. Optimism in CD-RISC was a protective factor, and passive coping styles and higher SDS score were risk factors for anxiety.LimitationsThis study adopted a cross-sectional design and used self-report questionnaires.ConclusionThe mental health of the public, especially females, the younger and less educational populations, and unmarried individuals, should be given more attention. Individuals with high level of mental resilience and active coping styles would have lower levels of anxiety and depression during the outbreak of COVID-19. (shrink)

In recent years, many studies have been done to identify the factors that affect teacher emotions at schools. However, the empirical evidence on how teachers’ emotions influence students’ outcomes and performance is not extensive. Against this background, this study explored the correlation between teacher EI and student academic achievement and possible mechanisms may lie in this relationship. A sample of 365 Chinese teachers from 25 public middle schools participated in this study by completing measurements of teacher EI, teacher work engagement, (...) and teacher self-efficacy. The student academic achievement was assessed by the grades of the previous term reported by the students. The results indicated that teacher work engagement partially mediated the path from teacher EI and student academic achievement. Moderated mediation further showed that teachers with high self-efficacy had a more significant positive impact on the relationship between teacher work engagement and student academic achievement than teachers with low self-efficacy. The limitations of this study were also discussed. (shrink)

Traffic congestion is a common problem in many countries, especially in big cities. At present, China’s urban road traffic accidents occur frequently, the occurrence frequency is high, the accident causes traffic congestion, and accidents cause traffic congestion and vice versa. The occurrence of traffic accidents usually leads to the reduction of road traffic capacity and the formation of traffic bottlenecks, causing the traffic congestion. In this paper, the formation and propagation of traffic congestion are simulated by using the improved medium (...) traffic model, and the control strategy of congestion dissipation is studied. From the point of view of quantitative traffic congestion, the paper provides the fact that the simulation platform of urban traffic integration is constructed, and a feasible data analysis, learning, and parameter calibration method based on RBF neural network is proposed, which is used to determine the corresponding decision support system. The simulation results prove that the control strategy proposed in this paper is effective and feasible. According to the temporal and spatial evolution of the paper, we can see that the network has been improved on the whole. (shrink)

This research examines the effect of an individual difference variable that reflects the extent to which one desires positive evaluations from others—that is, face consciousness on consumer energy-saving behavior—as well as the mechanism through which the effect occurs and conditions under which it varies. Drawing upon the means-end theory of lifestyles, we propose that face consciousness increases a status-seeking lifestyle and thus decreases energy-saving behavior. Moreover, the negative relationship between status-seeking lifestyle and energy-saving behavior is contingent upon a perceived seriousness (...) of environmental problems and perceived environmental responsibility, such that the indirect and negative effect of such face consciousness is stronger for consumers who perceive less serious environmental problems and less environmental responsibility. Results from an experimental study and a field study using samples of Chinese consumers provide consistent evidence for the hypothesized model. Theoretical and practical implications for energy-saving behavior are also discussed. (shrink)

Background: Chinese Taoist cognitive therapy (CTCT), a culture-oriented psychological therapy for Chinese mental well-being, has been proposed for decades. However, the evidence for its effects is unclear. This study aimed to systematically assess the effect of this therapy on symptoms of depression and anxiety in Chinese adults. Methods: Relevant studies were searched from major electronic databases through November 2018 without language limits. Several search terms used include “anxiety” OR “depression” AND “Taoism” OR “Daoism” OR “Chinese Taoist Cognitive Therapy”. A total (...) of 11 clinical trials focusing on CTCT were included in this meta-analysis. Random-effects meta-analytical models were conducted. Heterogeneity and publication bias were also explored. Results: Eight clinical trials for 580 subjects were included. The majority of these studies explored samples with depressive symptoms. Overall, CTCT significantly reduced depressive symptoms with a small positive effect (SMD = 0.16, 95% CI: -0.36-0.68). Medium-to-large effect sizes were observed across individuals with clinical or nonclinical depression and chronic physical diseases (SMD = 0.70, 95%CI: 0.27-1.13 and SMD = 0.72, 95%CI: 0.09-1.35, respectively). However, the effectiveness for anxiety symptoms remains debatable. Conclusions: Our findings hold promise that CTCT can help reduce depressive symptoms in Chinese adults, including patients with chronic physical diseases and clinical or nonclinical depression. Our findings may be generalized to Chinese communities in other countries. (shrink)

When navigating in a new environment, it is typical for people to resort to external guidance such as GPS, or people. However, in the real world, even though navigators have learned the route, they may still prefer to travel with external guidance. We explored how the availability of feedback and the source of external guidance affect navigation decision-making on experienced routes in the presence of external guidance. In three experiments, participants navigated a simulated route three times and then verbally confirmed (...) that they had learned it. They then travelled the same route again, accompanied with no, correct, or incorrect direction guidance, which latter two were provided by a GPS (Exp.1), a stranger (Exp.2), or a friend (Exp.3). Half of the participants received immediate feedback on their navigation decisions, while the other half without feedback did not know if they had selected the correct directions. Generally, without feedback, participants relied on external guidance, regardless of the direction sources. Results also showed that participants trusted the GPS the most, but performed best with their friends as a direction source. With feedback, participants did not show differences in performance between the correct and incorrect guidance conditions, indicating that feedback plays a critical role in evaluating the reliability of external guidance. Our findings suggest that incorrect guidance without any feedback might disturb navigation decision-making, which was further moderated by the perceived credibility of direction sources. We discuss these results within the context of navigation decision-making theory and consider implications for wayfinding behaviors as a social activity. (shrink)

Public policy and public opinion directly affect the image of the government, but due to the lack of appropriate monitoring and early warning tools, the government’s handling of credit changes is seriously lagging behind. In response to this problem, this paper integrates the internet, public information, market credit information, and other data, uses hidden Markov models and natural language processing technology, and establishes a modern government public policy and public opinion monitoring and early warning model to evaluate government credit in (...) real time; the government can formulate relevant policies based on the evaluation results to improve the government’s governance capabilities. Empirical analysis shows that, based on the dynamic scoring framework and Markov model, the government credit monitoring and early warning models established, respectively, have 90% of the reference value, and the analysis results have the same reference. This method can effectively predict the trend of hot online public opinion. The subsequent establishment of an online public opinion early warning system and an online public opinion guidance mechanism provided theoretical support. (shrink)

Is the statue made of copper identical with the piece of copper from which it is made? This question was argued for years since Allan Gibbard published Contingent Identity in 1975. Before arguing for or against identity, I try to clarify different usages of the word “identity” and the conditions under which Leibniz’s Law is effective. In our language, there are four concepts of identity, and Leibniz’s Law works differently in each case. Both monist and pluralists fail to distinguish the (...) four concepts. However, monist could be right. (shrink)

Fostering subordinate moqi is a significant method to improve the cooperating quality and promote positive outcomes. However, little is known about the influencing factors and mechanisms of subordinate moqi. To address this issue and explore the influencing factors of subordinate moqi, we draw on self-categorization theory to develop a mediation model to examine whether and how deep-level similarity affects subordinate moqi, casting the leader-member exchange as a mediator. A two-wave online survey was conducted and 316 data was collected. A Structure (...) Equation Modeling analysis was used to test all hypotheses with Mplus 7. Results showed that the deep-level similarity could positively predict subordinate moqi and LMX, respectively. Additionally, LMX was a significant predictor of subordinate moqi as well as it mediated the positive relationships between deep-level similarity and subordinate moqi. These findings expand our understanding of the antecedents of subordinate moqi. It is suggested that developing subordinates’ deep-level similarity with supervisors and LMX relationships are instrumental in cultivating subordinate moqi which promote positive outcomes. Organizations should integrate effective management programs into managerial strategies to enhance deep-level similarity and LMX, in turn, fosters subordinate moqi. (shrink)

It could be said that after Hegel’s, Philosophy in the world begun its downturn, falling in chaos during more than one hundred years. The Science study the specific thing replaced the philosophy as the King position in human’s knowledge. But, in fact, the science was born by philosophy. From 19th century, people could study the specific object by way of science, not philosophy. Of course, the best way to study the specific thing is the science. But, to study the onto, (...) science does not work. The onto is the target object of philosophy. The specific object is not the target study object of philosophy! The object for philosophy is the onto. But, in 19th and 20th century, people did not know this very well, viewing all the specific thing was studied very well by science, the scholars of philosophy were very upset. this is because they did not know the target object of philosophy is the onto, not the specific object. If they want to get a kind of specific object in nature to be the object of philosophy, of course, they would get defeated by the science, which was really the history. Finally, some got a field, called the phenomena, then, the phenomenology begun, but the phenomenology is not philosophy. Now, the human have got very large achievement in study of nature object. as per ontology and cognition logic, the onto is the root basis of every object, but, to get to know the specific object is the correct way for to get to know the onto. Now, with theachievement of study various object, philosophy could get new progress in study the onto. Following is the abstract explain why the phenomenology is not philosophy. From the very beginning of philosophy, people know the reality, the onto is hided in the phenomena, philosophy’s task is to find out the essence, the reality hided in the phenomena. At the time about early 20th century, there came out a kind of philosophy, called Phenomenology, ever developed ardently during last century for several decades, even now, it is still there, continue split philosophy, bring confusion to philosophy. Philosophy was produced by study the essence of object, especially the onto of everything. but in Phenomenology, there is no essence or the onto hided in the nature, it regard the phenomena as the study object, it deny the onto exists. The onto is the target object of philosophy over the past 2000 more years, but the phenomenology deny the onto, then, how could the phenomenology still regard itself as “philosophy”? Obviously, the phenomenology is not philosophy. Of course, the onto is there, longlive with the nature, the sun, the space. To get to know the onto, is the long live study for human. So, the phenomenology is wrong, at least wrong in the regard of the philosophy. Because of phenomenology’s ridiculous study object and theme, it produced various kinds of ridiculous answer and explain, by its main study such as Edmund Husserl, Martin Heidegger, Jean Paul Sartre, Albert Camus, and latter, The structuralism, post structuralism and post modernism ect.. Finally, philosophy was split, falling apart in everything, it seemed any kind thing or phenomena could produce a kind of philosophy, what more ridiculous is any kind of phenomena ever expected to explain the nature the world the space by its several points of view about itself. this make philosophy look like garbage, loss the glory it ever had. Now, it is high time to say that the phenomenology, since it deny the essence and the onto in the nature, is not philosophy. It shall not be called as philosophy. philosophy’s target object is the onto, which is the root basis of everything, the root theory in the space. (shrink)
