To improve sustainable practices and attract investors, companies in emerging markets have increasingly embraced strategies for inclusion in rapidly expanding sustainability indices. However, most early studies on socially responsible investment or sustainability investment have only focused on exploring the relationship between corporate sustainability and firm value. Moreover, little has been done to explore the practices of emerging market companies for engaging with a sustainability index. To address this research gap, we employed the decision-making trial and evaluation laboratory method to identify (...) critical factors that influence the inclusion of emerging market companies in the Dow Jones Sustainability Index. Five critical factors and best practices were identified based on the analysis of seven Taiwanese electronics companies that have been listed in the DJSI for several consecutive years. Our results provide insights on the critical factors and best practices that reinforce the sustainable practices of emerging market companies for inclusion in the DJSI. This study also contributes to the literature by investigating the engagement of emerging market companies with the DJSI. (shrink)

The unethical behavior of a business founder often leads to negative publicity which substantially affects positive corporate image. The amount of negative publicity relating to business founders’ unethical behavior is on the rise in the age of online social media in China. Based on the stimulus–response theory and balance theory, this paper developed a theoretical model to examine how negative publicity about a business founder’s unethical behavior affects corporate image. The proposed model was tested by the partial least squares technique. (...) Results show that perceived severity, publicity intensity and recovery performance are predictors of corporate image: perceived severity has a negative impact on positive corporate image; publicity intensity and recovery performance have positive impacts on positive corporate image; and founder image mediates the relationships between the three predictors and corporate image. Moreover, initial consumer impression of business founders has a positive impact on positive corporate image. (shrink)

This research examines the relationship between physical exercise and subjective well-being via the mediation of body image and self-esteem, thereby providing some suggestions on the improvement of subjective well-being in college students. A total of 671 college students from three universities of science and engineering in Sichuan, China voluntarily participated in the survey. Descriptive statistics, Pearson’s product-moment correlation, and mediation model analysis were conducted using the SPSS statistics 19.0. The results showed that the physical exercise level was positively and significantly (...) correlated with the subjective well-being level in each dimension college students with the medium and high level of exercise have higher subjective well-being than those with the low level of exercise, and body image and self-esteem played a complete mediation role between physical exercise and subjective well-being. The mediation analysis revealed two paths: first, the single mediating path via self-esteem [indirect effect = 0.087, 95% CI: ] and second, the serial mediating path via body image and self-esteem [indirect effect = 0.038, 95% CI: ]. Some practical implications have been discussed on the physical exercise intervention for promoting the subjective well-being level in college students. (shrink)

Social media users have increased rapidly in recent years; however, most are “silent users” who rarely share information online. To maintain social media companies’ stable operation and development, this research explored the effects of flow experience and identity formation on users’ intrinsic motivation to facilitate aggressive, spontaneous, and habitual participation in virtual communities. A total of 487 valid questionnaires were collected and underwent regression analysis. The results revealed that all three intrinsic motivations had a significant impact on social media participation, (...) with social interaction exerting the strongest influence. Flow experience and identification had significant, partial mediating effects on the relationship between motivation and participation. Several suggestions were provided based on the results to help social media enterprises increase user participation. It is hoped that this research could facilitate in transforming users into habitual participants to keep the operations of the virtual community stable and enduring. (shrink)

We explore corporate environmental accountability by examining how carbon emissions affect voluntary climate-related information disclosure based on TCFD principles. Using computerized textual analysis to measure such climate-related disclosure, our results show that firms with higher levels of carbon emissions disclose more climate-related information. This relation is stronger in firms belonging to carbon-intensive industries, such as energy, materials, and utilities. We also examine this relationship at the category level for Governance, Strategy, Risk Management, and Metrics and Targets, finding that carbon emissions (...) drive disclosure in all categories except in Governance. Overall, our findings indicate that high carbon emitting firms appear to discharge their corporate accountability by increasing climate-related disclosure, consistent with legitimizing their potentially unethical actions and submitting to stakeholder and societal pressure.

BackgroundTo investigate the factors related to approval after review by an Institutional Review Board, the structure equation model was used to analyze the latent variables ‘investigators’, ‘vulnerability’ and ‘review process’ for 221 proposals submitted to our IRB.MethodsThe vulnerability factor included vulnerable cases, and studies that involved drug tests and genetic analyses. The principal investigator factor included the license level of the PI and whether they belonged to our institution. The review factor included administration time, total review time, and revision frequency. (...) The revision frequency and total review time influenced the efficiency of review.ResultsThe latent variable of reviewing was the most important factor mediating the PIs and vulnerability to IRB review approval. The local PIs moderated with genetic study and revision frequency had an impact on the review process and mediated non-approval.ConclusionsBetter guidance of the investigators and reviewers might improve the efficiency with which IRBs function.

Single-sided deafness (SSD) or profound unilateral hearing loss obligates the only serviceable ear to capture all acoustic information. This loss of binaural function taxes cognitive resources for accurate listening performance, especially under adverse environments or challenging tasks. We hypothesized that adults with SSD would manifest both functional and structural brain plasticity compared to controls with normal binaural hearing. We evaluated functional alterations using magnetoencephalographic imaging (MEGI) of brain activation during performance of a moderately difficult auditory syllable sequence reproduction task and (...) assessed structural integrity using diffusion tensor magnetic resonance imaging (DTI). MEGI showed the SSD cohort to have increased induced oscillations in the theta band over the left superior temporal cortex and decreased induced gamma band oscillations over the frontal and parietal cortices between 175-475 ms following stimulus onset. DTI showed the SSD cohort to have extensive fractional anisotropy reduction in both auditory and non-auditory tracts and regions. Overlaying functional and structural changes revealed by the two imaging techniques demonstrated close registration of cortical areas and white matter tracts that expressed brain plasticity. Hence, complete loss of input from one ear in adulthood triggers both functional and structural alterations to dorsal temporal and frontal-parietal areas. (shrink)

ObjectiveBasic combat training is a kind of necessary high-intensity training to help each military recruit convert into a qualified soldier. In China, both the physical fatigue and passive psychological state have been observed in new recruits during BCT. However, after same-intensity training, the degree of fatigue and passive mood vary among recruits. Therefore, this study aimed to explore the effect of BCT on mood state of recruits with different physical fitness levels from a perspective of fatigue.Materials and methodsBefore and after (...) BCT, the degree of fatigue and mood state of participants were evaluated via the Borg Rating of Perceived Exertion Scale and Profile of Mood States Questionnaire immediately after 20 push-ups as RPE and POMS scores [total mood disturbance, passive mood and positive mood ]. The participants were divided into two groups according to the RPE score measured after BCT: group 1: RPE score after BCT < 13 and group 2: RPE score after BCT ≥ 13.ResultA total of 564 recruits were included. After BCT, in group 1, TMD and passive mood Ttension, Tfatigue, Tdepression, Tconfusion declined significantly, but positive mood both increased significantly ; while in group 2, only Tanger and Testeem increased significantly.ConclusionBCT could alleviate passive mood and add to positive mood for recruits with better physical fitness, while had no ameliorative effects on or even deteriorate most of the passive mood for recruits with worse physical fitness.

As teams of people increasingly incorporate robot members, it is essential to consider how a robot's actions may influence the team's social dynamics and interactions. In this work, we investigated the effects of verbal support from a robot on human team members' interactions related to psychological safety and inclusion. We conducted a between-subjects experiment where the robot team member either gave verbal support or did not give verbal support to the human team members of a human-robot team comprised of 2 (...) human ingroup members, 1 human outgroup member, and 1 robot. We found that targeted support from the robot had a positive effect on outgroup members, who increased their verbal participation after receiving targeted support from the robot. When comparing groups that did and did not have verbal support from the robot, we found that outgroup members received fewer verbal backchannels from ingroup members if their group had robot verbal support. These results suggest that verbal support from a robot may have some direct benefits to outgroup members but may also reduce the obligation ingroup members feel to support the verbal contributions of outgroup members.

Supporting families of people with developmental disabilities from culturally diverse backgrounds is receiving increased attention in the era of globalisation. However, there is little information about how disability policy and cultural values work together to support families. This article examined how disability policy and Chinese cultural values influence family care of children and young people with developmental disabilities. By comparing qualitative interview data from Chinese families in Taipei (15) and Sydney (10), we analysed how their expression of cultural values in (...) family care differs by policy context, relative to ethics of care claims for recognition, rights and redistribution. We found that positive expressions of Chinese culture in family care fade if policies do not complement them. Policies can alleviate potential tension with cultural values in three ways: reinforcing family capacity to care; ensuring the rights of both family caregivers and people with disabilities; and extending care choices for families. These approaches resonate with ethics of care principles. We argue that culturally responsive disability policy for families means working with cultural values to achieve ethics of care. This implies that incorporating principles of ethics of care could inform cultural responsiveness in disability policy development. (shrink)

Retailers like to use different colors to present the sale price and original price when they are presenting a promotion price. How does the inconsistent color presentation of the prices influence consumers’ purchase likelihood? The extant research does not consider this question. This article will address this question. Drawing on incongruence theory and the persuasion knowledge model, this article proposes that when the color of the sale price is inconsistent with that of the original price, consumers show less preference for (...) the sale price. The reason is that consumers perceive the price as being less trustworthy, which leads to a lower purchase likelihood. Furthermore, this effect is affected by the brand awareness of products. Specifically, when products are less-known brands, the inconsistent colors of the sale price and original price will lead to a lower purchase likelihood. In contrast, when products are well-known brands, the inconsistent colors of the sale price and original price will lead to a high purchase likelihood. In this article, four studies are used to verify these hypotheses, and implications of theory and practice of the present research are discussed. (shrink)

Robust techniques critically improve bearing-only target localization when the relevant measurements are being corrupted by impulsive noise. Resistance to isolated gross errors refers to the conventional least absolute residual method, and its estimate can be determined by linear programming when pseudolinear equations are set. The LAR approach, however, cannot reduce the bias attributed to the correlation between system matrices and noise vectors. In the present study, perturbations are introduced into the elements of the system matrix and the data vector simultaneously, (...) and the total optimization problem is formulated based on least absolute deviations. Subsequently, an equivalent form of total least absolute residuals is obtained, and an algorithm is developed to calculate the robust estimate by dual ascent algorithms. Moreover, the performance of the proposed method is verified through the numerical simulations by using two types of localization geometries, i.e., random and linear. As revealed from the results, the TLAR algorithm is capable of exhibiting significantly higher localization accuracy as compared with the LAR method. (shrink)

Most studies have examined the outcomes of patients supported by extracorporeal membrane oxygenation as a life-sustaining treatment. It is unclear whether significant social events are associated with the use of life-sustaining treatment.

This study focuses on CEO hubris and its detrimental effect on corporate financial performance along with an examination of critical corporate governance contingencies that may moderate the negative effect. From 654 observations of 164 Korean firms over the years 2001–2008, we found that CEO power exacerbated the negative effect of CEO hubris on corporate financial performance, whereas board vigilance mitigated it. This study provides empirical evidence that entrenchment problems arising from CEO hubris would be exacerbated as CEOs become more powerful, (...) but weakened as board of directors become more vigilant. Theoretical contributions and practical implications will be discussed. (shrink)

Test anxiety is a widespread and primarily detrimental emotion in learning and achievement settings. This research aimed to explore the autonomic nervous system response patterns of test-anxious individuals in response to evaluative stress. By presenting a standard interview task, an evaluative scenario was effectively induced. Heart rate variability, a biomarker that can accurately reflect the ANS activity, was used to reflect the physiological responses of 48 high test-anxious subjects and 49 low test-anxious subjects. Results indicate that: both groups show a (...) significantly increased emotional arousal in the evaluative scenario; high test-anxious individuals show a significantly decreased emotional pleasantness in the evaluative scenario, whereas low test-anxious individuals show no significant changes; both groups show a significantly increased low-frequency HRV; high test-anxious individuals show a significantly decreased high-frequency HRV and root mean square of successive heartbeat interval differences, whereas low test-anxious individuals remain stable. These findings suggest that high test-anxious individuals display an increased sympathetic nervous system activity and a decreased parasympathetic nervous system activity in response to evaluative stress, while low-anxious individuals display an increased SNS activity and a stable PNS activity in response to evaluative stress.

Objective: The objective of this study was to evaluate the psychometric properties of the Chinese version of the decision regret scale. Methods: The data of 704 patients who completed the DRSc were used for the analyses. We evaluated the construct, convergent/discriminant, and known-group validity; internal consistency and test–retest reliability; and the item invariance of the DRSc. A receiver operating characteristic curve was employed to confirm the optimal cutoff point of the scale. Results: A confirmatory factor analysis indicated that a one-factor (...) model fits the data. The internal consistency and test–retest reliability [intraclass correlation coefficient = 0.71] of the DRSc were acceptable. The DRSc demonstrated unidimensionality and invariance for use across the sexes. It was confirmed that an optimal cutoff point of 25 could discriminate between patients with high and low decisional regret during clinical practice. Conclusion: The DRSc is a parsimonious instrument that can be used to measure the uncertainty inherent in medical decisions. It can be employed to provide knowledge, offer support, and elicit patient preferences in an attempt to promote shared decision-making. (shrink)

In 2015, the Chinese pharmacologist, Tu Youyou, was awarded the Nobel Prize for Physiology or Medicine for the discovery of artemisinin. Traditional Chinese medicine (TCM) was the source of inspiration for Tu's discovery and provides an opportunity for the world to know more about TCM as a source of medical knowledge and practice. In this article, the value of TCM is evaluated from an ethical perspective. The characteristics of ‘jian, bian, yan, lian’ are explored in the way they promote accessibility (...) and economic efficiency for TCM. The article also examines how the increased use and prevalence of TCM reflects the scientific, cultural, and ethical values of TCM and their increasing attraction in meeting major challenges to medicine and health systems currently and in the future. The article discusses safety issues within TCM, which is a controversial area, and also comments on some shortcomings and challenges which pose difficulties for more widespread and greater uptake of TCM‐derived clinical or therapeutic interventions. The article concludes that TCM is generally safe if it is used according to TCM theory and where such applications are cognizant of the strengths and weaknesses of TCM. TCM has important bioethical values which may inform potential measures for meeting challenges facing global health care systems and the article argues that it can have an increasing role in improving human health.

The Zhouyi is the first of the Chinese classics and has, since medieval times, fascinated scholars from different parts of the world, who have produced numerous studies and expressed a dazzling array of views on its nature. It is argued that the Zhouyi has retained its exalted status and enduring appeal largely because it is an open book amenable to all kinds of appropriations and manipulations, and its openness comes from its being a semiotic system whose principle of composition warrants (...) unlimited interpretations. Through a semiotic-cum-philosophical inquiry, it is shown that the Zhouyi is first and foremost a system of representation, and because of its unique structure and principle of signification it forms an open hermeneutic space with infinite possibilities of interpretation.

John Rawls presents a liberal conception of international justice in his book The Law of Peoples, and this liberal conception of international justice has inspired a variety of responses from various perspectives. However, it seems that most such responses come from western perspectives, and that there is hence a corresponding paucity of seriously challenging responses based on non-western traditions. This paper aims to analyze Rawls’s liberal conception of international justice in view of the concept of natural justice expressed within the (...) Book of Change in order to illuminate the limitations and problems of Rawls’s conception in practice as well as in theory. Rawls employs the idea of political liberalism to construct a liberal conception of international justice that can be applied to a society of societies. Rawls addresses the eight principles for justice among free and democratic peoples, which have been historically accepted by western peoples. He admits that these principles are incomplete. There is no theoretical order among the eight principles equivalent to the lexical order of the two principles of justice in A Theory of Justice. There are no guidelines or basic principles for resolving the problem of priority that arises when the principles are themselves in conflict with one another. This situation may generate competing conceptions of justice within the society of peoples. Rawls mentions natural justice in his explanation for the extension of liberal political principles to decent hierarchical peoples. He takes as an example of natural justice the rule of formal equality that “similar cases be treated similarly.” He does not develop any further the idea of natural justice for his theory of international justice, which could potentially span the gap between his ideal theory and non-ideal theory, or enhance the reasonableness of his international justice, especially for non-liberal peoples. The Book of Change expresses the idea of natural justice that underlies the principle of Yin-Yang, which differs fundamentally from the liberal contract paradigm. The paper will argue that the idea of natural justice should be seriously considered for justice among peoples since it can provide the bedrock for criticizing non-public reason as well as public reason.

Spanning the 19th and 20th centuries and identifying multiple waves of modernization, this book illustrates how principles originating in Chinese Confucianism have impacted the modernization of East Asia, especially in Korea. It also analyzes how such principles are exercised at personal, interpersonal and organizational levels. As modernization unfolds in East Asia, there is a rising interest in tradition of Confucianism and reconsider the relevance of Confucianism to global development. This book considers the actual historical significance of Confucianism in the modernization (...) of the three nations in this region, China, Korea, and Japan through the nineteenth century and early twentieth century to the aftermath of the end of World War II. Examining the existing literature dealing with how Confucianism has been viewed in connection with modernization, it provides insight into western attitudes towards Confucianism and the changes in perceptions relative to Asia in the very process of modernization itself.

In November 1989, the Berlin Wall, the symbol of the Cold War between the West and the East, came tumbling down. In December 1991, a superpower, the Soviet Union, ceased to exist.

Indeed, it was perhaps the greatest irony of all.

Science and technology have changed all aspects of our lives, including the mode of narration, from traditional stories to data stories. Storytellers have been integrating visualizations into their narratives.

In lieu of an abstract, here is a brief excerpt of the content:RusselL on Chinese Civilization 23 RUSSELL ON CHINESE CIVILIZATIONI Yu DONG Ph}losophy / McMaster University Hamilton, Ont., Canada L8s 4K1 1 I am indebted to Nicholas Griffin for his valuable comments and encouragement. I thank Marty Fairbairn and Perer Lovrick for many corrections in the paper. I am also greatly indebred to Ken Blackwell for his helpful criticisms and suggesrions. • (London: Allen & Unwin, 1922), p. 20. (...) 3 Karl Popper, The Open Society and Its Enemies (Princeron: Princeton U. P.), p. 173· B ertrand Russell arrived in China with Dora Black in October 1920. World War I had deepened his disillusionment with both the capitalist system and Western civilization in general. Seeking a socialist solution, he had visited Soviet Union just a few months before. But he had found that the Communist state there presented an unappealing alternative to the capitalist West in that it treated its citizens as slaves. The sad mood in which he "set out for China to seek a new hope"2 was described in his The Problem of China, published in 1922 after his nine-month visit: "It was on the Volga, in the. summer of 1920, that I first realized how profound is the disease in our Western mentality, which the Bolsheviks are attempting to force upon an essentially Asiatic population, just as Japan and the West are doing in China" (p. 18). The 1920S were a time when China, both as a nation and as a civilization, was in deep trouble. Her young people were eagerly looking outside their country to find a way of saving her. Since the 1840 Opium War, the Western Powers had poured into China, which had been a closed society, at least in Karl Popper's sense,3 for more than 3,000 years. With the collapse of the Qing dynasty in 19I1, China had been thrown into a state of anarchy by feuding warlords. The Great World Powers had both politically and economically dominated China through successive wars with her;4 through demanding indemnities, the cession of territory, fixed tariffs, etc.; and through controlling the corrupt and inept central government and warlords. Meanwhile, China was plagued by famine, piracy, brigandage, incipient rebellion,5 and the failures of various attempts at reform and revolution.6 China was well on the way toward disintegration, divided into "spheres of influence" by Britain, Germany, France, Russia and, especially, Japan. In the 1920S, China was also in the period of the May Fourth Movement-named after a popular student protest on 4 May 1919against foreign imperialism and an impotent Chinese government. It was agitated by the Treaty of Versailles which transferred, at the request ofJapan, the properties and privileges of the German sphere of influence in the Shandong Peninsula to Japan. This movement advocated learning science and adopting democratic principles in order to save China. It is important in Chinese history as a symbol of Chinese awareness of the need for the most profound changes in her tradition. All of these factors constituted the background to Russell's visit to China and thus affected the formation of his distinct view of the problem of China.? The invitation to him was a part of Chinese efforts in seeking methods from the West to save their country. Russell had already been known in China as a great philosopher, not only for his philosophy of logic and science, but also for his views on social problems. Some Chinese had access to his books: Principles ofSocial Reconstruction (1916), Political Ideals (1917), Roads To Freedom (1918), and magazine publication of parts of The Practice and Theory ofBolshevism (1920).8 Considering this background, it is quite understandable why 4 For example, Brirain and France 1856-60, Japan 1894-95, 1914-15. 5 For example, Taiping 1850-65, and the Boxer Rebellion of 1900. 6 The revolution of 1911 actually just changed the name of the government, rather than the reality of society. 7 A detailed description of this background as "psychological roots" can be seen in S. P. Odgen, "The Sage in the Inkpot", Modern Arian Studies, 16 (1982): 529-600. 8 For example, Zhang Shenfu, a student originally majoring in mathematics in Beijing University, had read almost all of...

The paper aims to show how Japanese theoretical physics groups emerged between the First and Second World Wars. First, it will be argued that by the early 1930s the Japanese physics community had been predominantly inclined towards experimental physics and that several academic, cultural, and social factors had worked for the maintenance of this status quo. Next, how the situation slowly changed during the early 1930s, and how the young theoretical physicists successfully established a bridgehead during the mid-1930s will be (...) analysed. Four different elements are suggested: the dazzling success of quantum mechanics and its spread in the West; the dominance of experimental physics and its effect on the university system; cultural/social influence; and the emergence of the research network.

Emotion is closely associated with language, but we know very little about how children express emotion in their own writing. We used a large‐scale, cross‐sectional, and data‐driven approach to investigate emotional expression via writing in children of different ages, and whether it varies for boys and girls. We first used a lexicon‐based bag‐of‐words approach to identify emotional content in a large corpus of stories (N>100,000) written by 7‐ to 13‐year‐old children. Generalized Additive Models were then used to model changes in (...) sentiment across age and gender. Two other machine learning approaches (BERT and TextBlob) validated and extended these analyses, converging on the finding that positive sentiments in children's writing decrease with age. These findings echo reports from previous studies showing a decrease in mood and an increased use of negative emotion words with age. We also found that stories by girls contained more positive sentiments than stories by boys. Our study shows the utility of large‐scale data‐driven approaches to reveal the content and nature of children's writing. Future experimental work should build on these observations to understand the likely complex relationships between written language and emotion, and how these change over development. (shrink)

This paper aims both to tackle the technical issue of deciphering Hobbes’s derivation of the sine law of refraction and to throw some light to the broader issue of Hobbes’s mechanical philosophy. I start by recapitulating the polemics between Hobbes and Descartes concerning Descartes’ optics. I argue that, first, Hobbes’s criticisms do expose certain shortcomings of Descartes’ optics which presupposes a twofold distinction between real motion and inclination to motion, and between motion itself and determination of motion; second, Hobbes’s optical (...) theory presented in Tractatus Opticus I constitutes a more economical alternative, which eliminates the twofold distinction and only admits actual local motion, and Hobbes’s derivation of the sine law presented therein, which I call “the early model” and which was retained in Tractatus Opticus II and First Draught, is mathematically consistent and physically meaningful. These two points give Hobbes’s early optics some theoretical advantage over that of Descartes. However, an issue that has baffled commentators is that, in De Corpore Hobbes’s derivation of the sine law seems to be completely different from that presented in his earlier works, furthermore, it does not make any intuitive sense. I argue that the derivation of the sine law in De Corpore does make sense mathematically if we read it as a simplification of the early model, and Hobbes has already hinted toward it in the last proposition of Tractatus Opticus I. But now the question becomes, why does Hobbes take himself to be entitled to present this simplified, seemingly question-begging form without having presented all the previous results? My conjecture is that the switch from the early model to the late model is symptomatic of Hobbes’s changing views on the relation between physics and mathematics. (shrink)

In the research of motion video, the existing target detection methods are susceptible to changes in the motion video scene and cannot accurately detect the motion state of the target. Moving target detection technology is an important branch of computer vision technology. Its function is to implement real-time monitoring, real-time video capture, and detection of objects in the target area and store information that users are interested in as an important basis for exercise. This article focuses on how to efficiently (...) perform motion detection on real-time video. By introducing the mathematical model of image processing, the traditional motion detection algorithm is improved and the improved motion detection algorithm is implemented in the system. This article combines the advantages of the widely used frame difference method, target detection algorithm, and background difference method and introduces the moving object detection method combining these two algorithms. When using Gaussian mixture model for modeling, improve the parts with differences, and keep the unmatched Gaussian distribution so that the modeling effect is similar to the actual background; the binary image is obtained through the difference between frames and the threshold, and the motion change domain is extracted through mathematical morphological filtering, and finally, the moving target is detected. The experiment proved the following: when there are more motion states, the recall rate is slightly better than that of the VIBE algorithm. It decreased about 0.05 or so, but the relative accuracy rate increased by about 0.12, and the increase ratio is significantly higher than the decrease ratio. Departments need to adopt effective target extraction methods. In order to improve the accuracy of moving target detection, this paper studies the method of background model establishment and target extraction and proposes its own improvement. (shrink)

ObjectiveThe effects and possible mechanisms of cerebellar high-frequency repetitive transcranial magnetic stimulation on swallowing-related neural networks were studied using resting-state functional magnetic resonance imaging.MethodA total of 23 healthy volunteers were recruited, and 19 healthy volunteers were finally included for the statistical analysis. Before stimulation, the cerebellar hemisphere dominant for swallowing was determined by the single-pulse TMS. The cerebellar representation of the suprahyoid muscles of this hemisphere was selected as the target for stimulation with 10 Hz rTMS, 100% resting motor threshold, (...) and 250 pulses, with every 1 s of stimulation followed by an interval of 9 s. The motor evoked potential amplitude of the suprahyoid muscles in the bilateral cerebral cortex was measured before and after stimulation to evaluate the cortical excitability. Forty-eight hours after elution, rTMS was reapplied on the dominant cerebellar representation of the suprahyoid muscles with the same stimulation parameters. Rs-fMRI was performed before and after stimulation to observe the changes in amplitude of low-frequency fluctuation and regional homology at 0.01–0.08 Hz, 0.01–0.027 Hz, and 0.027–0.073 Hz.ResultsAfter cerebellar high-frequency rTMS, MEP recorded from swallowing-related bilateral cerebral cortex was increased. The results of rs-fMRI showed that at 0.01–0.08 Hz, ALFF was increased at the pons, right cerebellum, and medulla and decreased at the left temporal lobe, and ReHo was decreased at the left insular lobe, right temporal lobe, and corpus callosum. At 0.01–0.027 Hz, ALFF was decreased at the left temporal lobe, and ReHo was decreased at the right temporal lobe, left putamen, and left supplementary motor area.ConclusionRepetitive transcranial magnetic stimulation of the swallowing cortex in the dominant cerebellar hemisphere increased the bilateral cerebral swallowing cortex excitability and enhanced pontine, bulbar, and cerebellar spontaneous neural activity, suggesting that unilateral high-frequency stimulation of the cerebellum can excite both brainstem and cortical swallowing centers. These findings all provide favorable support for the application of cerebellar rTMS in the clinical practice. (shrink)

BackgroundAthletes will increase their state anxiety under stress situations, which will lead to the decline of sports performance. The improvement of anxiety by probiotics has been reported, but there is a lack of research in the athlete population. The purpose of the current study is to explore the effectiveness of probiotics in improving athletes’ state anxiety and sports performance under stress situations.MethodsWe conducted this single-arm study in Chongqing Institute of Sports Technology. In the 8-week study, 21 Chongqing young divers were (...) given probiotic Bifidobacterium animalis subsp. lactis BB-12 daily. The state anxiety and sports performance of athletes were measured before, during, and after the intervention, and the gut microbiota of athletes was measured before and after the intervention.ResultsThe intervention results showed that cognitive state anxiety, somatic state anxiety, and anxiety emotion were improved. In terms of gut microbiota, the intervention did not change the gut microbial composition but increased the abundance of Bifidobacteriaceae. At the 8th week, the performance of athletes under stress was significantly improved.LimitationsFirst of all, due to the restriction of the number of subjects in this study, there was no control group. Secondly, although the athletes’ diet was recorded in this study, the influence of this factor on gut microbiota was not eliminated. Finally, the anxiety level of the athletes in this study was obtained through a self-report, lacking physiological data in state anxiety.ConclusionThe results show that probiotics intervention can improve the state anxiety of athletes under stress situation and improve the performance of athletes under stress situation.
