BackgroundMild cognitive impairment is a common neurological disorder. Moxibustion has been shown to be effective in treating MCI, but its therapeutic mechanisms still remain unclear. This study mainly aimed to investigate the modulation effect of moxibustion treatment for patients with MCI by functional magnetic resonance imaging.MethodsA total of 47 patients with MCI and 30 healthy controls participated in resting-state fMRI imaging scans. Patients with MCI were randomly divided into true moxibustion group and sham moxibustion group. The degree centrality approach was (...) applied to distinguish altered brain functions. Correlation analysis was then performed to examine the relationships between the neuroimaging findings and clinical symptoms.ResultsCompared with HCs, patients with MCI mainly showed decreased DC in the left middle frontal cortex and bilateral middle cingulate cortex. After moxibustion treatment, the SHAM group had no significant DC findings, while TRUE group mainly showed significant increased DC in the bilateral MFC and MCC, as well as decreased DC in the left middle occipital cortex. Repeated measures analysis of variance showed significant interactions between the two groups of patients with MCI. In addition, the higher Mini-Mental State Examination score was significantly positively correlated with increased DC in the right MFC and left MCC after moxibustion treatment.ConclusionOur findings demonstrate that the potential value of moxibustion treatment on MCI, which adds new insights into the popular view that moxibustion treatment may slow cognitive decline in patients with MCI.

The present study provides evidence that the activation strength produced by emotional stimuli must pass a threshold level in order to be consciously perceived, contrary to the assumption of continuous quality of representation. An analysis of receiver operating characteristics for attentional blink performance was used to distinguish between two models of emotion perception by inspecting two different ROC’s shapes. Across all conditions, the results showed that performance in the attentional blink task was better described by the two-limbs ROC predicted by (...) the Krantz threshold model than by the curvilinear ROC implied by the signal-detection theory.

This paper examines the generalization of the Internet address term “family” (jiārénmen), a recently emerging phenomenon in language use from the perspective of Pragmatic Identity Theory. The main thrust of this research is to reveal the pragmatic identities and pragmatic functions involved in the use of “family” (jiārénmen). The core point has been arrived at by using a combination of quantitative and qualitative analyses to explore relevant cases collected from WeChat, Weibo, and in-person conversations. Research findings demonstrated that in different (...) contexts, the address term “family” (jiārénmen) can construct various pragmatic identities, all of which belong to the deviational identity opposite to the default identity. Notably, the construction of these identities functions to patch up address terms slot, promote relationships, and satisfy transactional needs. Furthermore, the generalization of the address term “family” (jiārénmen) mirrors the effect of the psychological mechanism of communicators and the Chinese family culture on discourse practice. The findings above contribute to extending the research line of Internet address term generalization, as well as a deeper understanding of the mechanism of the Internet address term “family” (jiārénmen) towards a harmonious language-using environment.

System security is essential for the operation of the island microgrid. However, the system security is generally threatened due to the presence of physical uncertainties and cyber attacks. In this article, a novel sliding mode load control strategy is proposed for the microgrid to mitigate cyber attacks and physical uncertainties. Firstly, a high-order disturbance observer is designed to estimate the unmeasurable factors in the microgrid. Secondly, a HODO-based sliding mode control strategy is proposed where the estimated value observed by the (...) HODO is applied to the sliding mode surface and control law. It can better guarantee the security of the isolated microgrid. Then, the stability of the HODO-based SMC is demonstrated by Lyapunov stability theory. Finally, simulation results show that the proposed control strategy has excellent control performance. (shrink)

The problem of generalizing the power option-pricing model to incorporate more empirical features becomes an urgent and necessary event. A new power option pricing method is designed for the financial market uncertainty that simultaneously involves randomness and fuzziness. The randomness in market uncertainty is modeled by a time-fractional diffusion model, which describes trend memory in underlying asset prices. The fuzziness in market uncertainty is characterized by a triangular interval type-2 fuzzy numbers, which better captures the fuzziness of underlying asset prices. (...) Considering the decision-maker’s subjective judgment, we show the price mean value with the possibility-necessity weight and pessimistic-optimistic index under the type-2 fuzzy environment. We develop the power option pricing model with the time-fractional diffusion model and the triangular interval type-2 fuzzy numbers. Furthermore, the analytic solutions of pricing call power option and put power option are obtained and verified by the variational iterative reconstruction method. Our study shows that power option pricing, which adopts the time-fractional model and the triangular interval type-2 fuzzy numbers, can better capture the trend memory and double fuzziness of the real market. In addition, a numerical example is provided to illustrate that the power option means the value is decreasing with respect to the pessimistic-optimistic index and is fluctuating with respect to the possibility-necessity weight index.

This paper explores whether a Student’s choice of major leads to certain personality traits and the reasons for this phenomenon. Specifically, we look at evidence from two Chinese universities, both of which specialize in agricultural studies. Using the Sixteen Personality Factor questionnaire and the Neuroticism Extraversion Openness Five-Factor Inventory questionnaire, we collected data from two groups of students: those who study agriculture-related majors, and those who study non-agriculture-related majors. The surveys all showed no significant change in personality traits during Students’ (...) freshman year. However, after 3 years of university study, significant personality trait changes were noted between seniors in the ARM and NARM groups. Whereas ARM seniors tended to be socially shy and lower in communicative competence, NARM seniors were better at expressing themselves and communicating with others. Although a Student’s choice of profession has an influence on their personality traits, it is not the only factor. The differences between ARM and NARM training models and curricula are also undoubtedly significant. Moreover, the bias against ARM in Chinese society further magnifies the differences in personality traits among students with different majors. (shrink)

Taking the semiotic landscaping of the Occupy Movement in Hong Kong in 2014 as an example, the article explores the semiotic relation between the materialization of signs and the constitution of a collectivity. Juxtaposing the concepts of ‘collective assemblage of enunciation’, ‘landscaping’ and ‘autoglottic space’, the article argues that collective enunciations are not autonomous from human agency. Instead, collective enunciations can be created by deliberate de-subjectification and de-personification in the materialization of signs.

Delay in seeking medical services is common in elderly populations, which leads to disease progression and life difficulty. This study aims to assess the prevalence of delay in medical visits and treatment and define associated effects and factors in patients with senile cataract, which may help obtain a better understanding of late-life psychopathology and provide the basis for interventions. Patients aged more than 60 years were prospectively recruited in Zhongshan Ophthalmic Center. All participants were diagnosed with binocular senile cataract and (...) decided to have primary surgery in ZOC. The distributions of the popularity of delaying outpatient visits and treatment, the degrees of visual impairment, the influences on quality of life, and the reasons for delaying treatment among participants were accessed by the descriptive statistics. Factors associated with the perceptions of cataract treatment were accessed using a binary logistic regression model. A total of 400 senile patients aged from 60 to 94 years were enrolled. At diagnosis, 82 participants had a low vision with monocular acuity of both eyes below 0.05. All participants have felt that their normal lives were affected, and 64 participants felt that their lives were affected severely. Only 17 participants have sought for medical services immediately after feeling vision loss, and 294 participants have felt vision loss since a year ago before seeking medical help. A total of 298 participants have delayed the surgery time, and 229 patients delayed it for more than 12 months. There were 147 participants delaying surgery on account of no knowledge about it and 114 participants delaying surgery because of fear. There are a high proportion of elderly patients with senile cataract delaying their outpatient visits and surgery treatment, whose normal lives were severely affected. Increasing medical service propaganda about cataract and other common diseases in elderly populations would probably be helpful for improving perceptions of diseases and decreasing medical delays. Public needs to draw more attention to the healthy and medical status of the elderly ocular patients. (shrink)

In face recognition systems, highly robust facial feature representation and good classification algorithm performance can affect the effect of face recognition under unrestricted conditions. To explore the anti-interference performance of convolutional neural network reconstructed by deep learning framework in face image feature extraction and recognition, in the paper, first, the inception structure in the GoogleNet network and the residual error in the ResNet network structure are combined to construct a new deep reconstruction network algorithm, with the random gradient descent and (...) triplet loss functions as the model optimizer and classifier, respectively, and it is applied to the face recognition in Labeled Faces in the Wild face database. Then, the portrait pyramid segmentation and local feature point segmentation are applied to extract the features of face images, and the matching of face feature points is achieved using Euclidean distance and joint Bayesian method. Finally, Matlab software is used to simulate the algorithm proposed in this paper and compare it with other algorithms. The results show that the proposed algorithm has the best face recognition effect when the learning rate is 0.0004, the attenuation coefficient is 0.0001, the training method is SGD, and dropout is 0.1, and the algorithm proposed in this paper has the largest mean average precision compared to other CNN algorithms. The correct rate of face feature matching of the algorithm proposed in this paper is 84.72%, which is higher than LetNet-5, VGG-16, and VGG-19 algorithms, the correct rates of which are 6.94%, 2.5%, and 1.11%, respectively, but lower than GoogleNet, AlexNet, and ResNet algorithms. At the same time, the algorithm proposed in this paper has a faster matching time and a higher correct matching rate than the joint Bayesian method, indicating that the deep reconstruction network algorithm proposed in this paper can be used in face image recognition, FE, and matching, and it has strong anti-interference.

Research on the relationship between emotions and job performance is ubiquitous, yet few scholars have examined the combined effects of different emotions. Drawing on the broaden-and-build theory and conservation of resources theory, we propose that employees’ daily emotion fluctuations will affect their service performance in opposite directions. Furthermore, we propose these effects will be moderated by psychological [i.e., regulatory emotional self-efficacy ] and physiological characteristics of the employees. Based on the experience sampling method, data obtained from 187 frontline employees of (...) 35 bank branches over 18 consecutive days supports our hypotheses. (shrink)

This study investigated the concept of individual differences (IDs) in the use of metacognitive strategies (planning, problem-solving, monitoring, and evaluating) and its relationship with task demand and learner performance within Kormos’ Bilingual Speech Production Model from the lens of Chinese English-as-foreign-language (EFL) learners in the context of integrated L2 speaking assessment. To measure metacognitive strategies, we administered an inventory on 134 Chinese EFL learners after they completed four integrated L2 speaking assessment tasks. Descriptive analysis and multiple linear regression were adopted (...) for data analysis, and results show that: (a) IDs displayed variance in Chinese EFL learners’ metacognitive strategy use; (b) among the four metacognitive strategies under investigation, problem-solving was reported to be used the most frequently in sharp contrast to monitoring, which had the lowest frequency; (c) metacognitive strategies worked interactively, responding to task demands involved in the four integrated L2 speaking assessment tasks; and (d) Chinese EFL learners’ use of metacognitive strategies, in individual and interactive working modes, had no relationship with their speaking performance. These results are expected to present some insights into the role of IDs in metacognitive strategy use during L2 speech production under assessment conditions, which will add robust evidence to the existing literature on L2 speaking, in particular on metacognitive strategy use in L2 speaking assessment. In the meantime, the findings will provide some empirical validation support for Kormos’ model, which will further provide some implications for L2 speaking instruction and L2 assessment. (shrink)

Mindfulness and accordant interventions are often used as complementary treatments to psychological or psychosomatic problems. This has also been gradually integrated into daily lives for the promotion of psychological well-being in non-clinical populations. The experience of mindful acceptance in a non-judgmental way brought about the state, which was less interfered by a negative effect. Mindfulness practice often begins with focused attention meditation restricted to an inner experience. We postulate that the brain areas related to an interoceptive function would demonstrate an (...) intrinsic functional change after mindfulness training for the mindful novices along with paying more attention to internal processes. To further explore the influence of mindfulness on the organization of the brain regions, both functional connectivity in the voxel and the region of interest level were calculated. In the current study, 32 healthy volunteers, without any meditation experiences, were enrolled and randomly assigned to a mindfulness-based stress reduction group or control group. Participants in the MBSR group completed 8 weeks of mindfulness-based stress reduction and rated their mindfulness skills before and after MBSR. All subjects were evaluated via resting-state functional MRI in both baselines and after 8 weeks. They also completed a self-report measure of their state and trait anxiety as well as a positive and negative affect. Pre- and post-MBSR assessments revealed a decreased amplitude of low-frequency fluctuations in the right anterior cingulate gyrus, left anterior and posterior insula, as well as left superior medial frontal gyrus in MBSR practitioners. Strengthened FC between right anterior cingulate cortex and aIC.R was observed. The mean ALFF values of those regions were inversely and positively linked to newly acquired mindful abilities. Along with a decreased negative affect score, our results suggest that the brain regions related to attention and interoceptive function were involved at the beginning of mindfulness. This study provides new clues in elucidating the time of evaluating the brain mechanisms of mindfulness novices. (shrink)

Profound sensorineural hearing loss is an auditory disability associated with auditory and cognitive dysfunction. Due to distinct pathogenesis, some associated structural and functional changes within the brain have been investigated in previous studies, but whole-brain structural alterations are incompletely understood. We extended the exploration of neuroanatomic differences in whole-brain structure in children with profound SNHL who are primarily users of Chinese sign language. We employed surface-based morphometry and subcortical analyses. T1-weighted magnetic resonance images of 26 children with profound SNHL and (...) 27 age- and sex-matched children with normal hearing were analyzed. Compared with the normal control group, children with profound SNHL showed diverse structural changes in surface-based and subcortical analyses, including decreased cortical thickness in the left postcentral gyrus, superior parietal lobule, paracentral lobule, precuneus, the right transverse temporal gyri, and the middle temporal gyrus; a noticeable increase in the Local Gyrification Index in the left precuneus and superior parietal lobule; and diverse changes in gray-matter volume in different brain regions. Surface-based vertex analyses revealed regional contractions in the right thalamus, putamen, pallidum, and the brainstem of children with profound SNHL when compared with those in the NC group. Volumetric analyses showed decreased volumes of the right thalamus and pallidum in children with profound SNHL. Our data suggest that children with profound SNHL are associated with diffuse cerebral dysfunction to cortical and subcortical nuclei, and revealed neuroplastic reorganization in the precuneus, superior parietal lobule, and temporal gyrus. Our study provides robust evidence for changes in connectivity and structure in the brain associated with hearing loss. (shrink)

Tourism in the Globally Important Agricultural Heritage System is critical to the inheritance and innovation of excellent traditional farming cultures. Based on social identity theory, this paper explored the process by which agricultural heritage systems’ creative performance influences tourists’ cultural identity through 406 questionnaires from Chinese tourists. The results indicate that creative performance affects tourists’ cultural identity through a dual perspective of knowledge transfer and novelty perception. Furthermore, perceived authenticity acts as a moderator, weakening the impact of creative performance on (...) tourists’ knowledge transfer, while perceived authenticity does not affect the process of tourists’ novelty perception. This research provides a fresh perspective on the sustainable development of agricultural heritage tourism. Meanwhile, it offers theoretical foundations and practical inspirations for the development of agricultural heritage’s creative tourism. (shrink)

The literature on error sharing has focused on employees’ cost–benefit assessment to predict whether employees will disclose self-made errors. Our study advances this line of research by adopting a different theoretical lens and examining leaders’ role in promoting employee error sharing. Drawing primarily upon social learning theory, we expected that when team leaders openly talk about their own errors within teams, through their behavior, they would set an example for team members and encourage members’ error sharing with team leaders. Based (...) on a sample of 353 employees within 95 teams, we found a positive link between leader error sharing and team member error sharing; in addition, we found that ethical leadership evaluation partially mediates this positive link. Moreover, we found that leader error sharing was positively related to the team error management climate, which moderated the relationship between ethical leadership evaluation and team member error sharing in such a way that the positive relationship becomes stronger under a higher error management climate. Our findings highlight the critical roles played by leaders in promoting employees’ error sharing. (shrink)

This paper presents an overall view of the Philosophy of Tian-xia, a particular form of neo-universalism developed by its author and very much debated in the last years. The system of Tian-xia, or ‘all-under-heaven’, is a philosophical re-elaboration of an ancient form of Chinese universalism. The world is constituted as a global unity and a basic concept of political philosophy. It aims at a world institution as a way to rethink all problems in the world as problems of the world. (...)Zhao Tingyang has analytically developed this view in some recent publications in Chinese. This article represents the most recent attempt to provide a synthetic view of his philosophy of ‘all-under-heaven’. (shrink)

According to the differences in the spatial-temporal co-location of human individuals, Alfred Schutz divided the contemporaneous lifeworld into two major realms: the realm of consociates made up of individuals sharing a community of space and a community of time, and the realm of contemporaries made up of individuals sharing neither a community of space nor a community of time. Extending Schutz''s phenomenological analysis to cyberspace, this paper delineates an emergent third realm – the realm of consociated contemporaries, in which individuals (...) share a community of time without sharing a community of space. A central argument of this paper is that the emergence of this social domain in cyberspace reconfigures the structure of the lifeworld by creating a new spatial-temporal condition of human contact, which gives rise to a new mode of human interaction and a new form of human relationship. The revolution of electronic communication is therefore a revolution of the ways in which human individuals come to construct we-relationships with one another in shared meaning contexts. (shrink)

All questions of thought lead back to philosophy. However, there remains a lack of clarity with regard to the preconditions of philosophy, especially the genesis of philosophy, that is, what is the first philosophical topic is not much clearer. It is often thought that philosophizing stems from being, or a state of existence, a legend from Greek philosophy. This paper attempts to reanalyze the precondition or the critical point of “how thinking is possible” by an archaeology of thought, so as (...) to pinpoint the first word that initiated human thought. The first thinking word must be a philosophical word. In examining historical conditions, oracle bone scripts and basic connectives in mathematical logic, this paper argues that human thought stemmed from negative words that are the first philosophical words. The trajectory is that negatives, upon entering the human lexicon, inspired the concept of possibility; only with various possibilities, consciousness begins to think freely, put forward issues worth being reflected and deliberated and provide different alternative answers. In short, the advent of the negative “no” marked the existence of the critical condition of thinking, i. e., thinking and philosophy started when the human being could say no, which is therefore the first term and the primary topic of philosophy.

Call ‘radical moral theorizing’ the project of developing a moral theory that not only tries to conform to our existing moral judgments, 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.
