In response to the Covid-19 pandemic, online learning has been carried out in many countries with different types of online learning models being promoted and implemented. In the global pandemic continues, the education environment is forced to change from traditional classroom or blended teaching mode to online learning teaching model. With the outbreak of COVID-19, China was the first to announce that online courses are to be implemented in February 2020. In China, whether online learning can replace traditional offline teaching (...) has become a topic worth discussing. Therefore, this study investigates university students in China by questionnaires and discussions of this topic. The study is based on the Push–Pull Mooring model. Based on 854 valid responses collected from an online survey questionnaire, structural equation modeling was employed to examine the research model. The results show that push effects, pull effects, and mooring effects all significantly influence users' switching intentions from offline to online learning platform. Finally, this study explores whether push–pull–mooring can be a reference for promoting and implementing online learning courses in Chinese colleges and universities in the future after the pandemic.

Low frequency oscillation is an important attribute of human brain activity, and the amplitude of low frequency fluctuation is an effective method to reflect the characteristics of low frequency oscillation, which has been widely used in the treatment of brain diseases and other fields. However, due to the low accuracy of the current analysis methods for low frequency signal extraction of ALFF, we propose the Fourier-based synchrosqueezing transform, which is often used in the field of signal processing to extract the (...) ALFF of the low frequency power spectrum of the whole-time dimension. The low frequency characteristics of the extracted signal are compared with those of FSST and fast Fourier transform through the resting-state data. It is clear that the signal extracted by FSST has more low frequency characteristics, which is significantly different from FFT. (shrink)

Although most existing studies have considered entrepreneurial bricolage as a means to overcome resource constraints in new ventures, few have explored the direct effects of entrepreneurial bricolage on employee creativity, particularly in the context of entrepreneurial internet firms. Drawing from multiple theories, this study proposes a cross-level mediation model for the trickle-down effects of entrepreneurial bricolage and business model innovation on employee creativity. By using a 2-wave longitudinal design, survey data were collected from multiple sources, including 49 leaders and 336 (...) employees from entrepreneurial internet firms in China. Multilevel structural equation modeling was applied to analyze the cross-level mediation model. The results show that both entrepreneurial bricolage and business model innovation failed to significantly and positively direct employee creativity. Furthermore, entrepreneurial bricolage exerted a cross-level influence on employee creativity that was sequentially transmitted through between-level business model innovation and within-level creative self-efficacy. The theoretical and managerial implications of these findings are also discussed. (shrink)

Atmospheric pollution is deteriorating, which has affected the evolution of respiratory disease for the exposed human worldwide. Thus, exploring the influence of air pollution on the evolution of disease transmission dynamics is a significant issue. In this article, a stochastic susceptible-infective epidemic model in a polluted atmospheric environment is investigated. The existence and uniqueness of the global positive solution are established. In virtue of the aggregation methods and Lyapunov function, the sufficient conditions of disease extinction, persistence, and existence of the (...) stationary distribution are established, respectively. TakingPM2.5concentration as the air pollutant index, numerical simulations are carried out to support these results. Our results indicated that the disease transmission dynamics are significantly associated with the environmental atmospheric pollution and fluctuation. (shrink)

The term "religious Daoism" first appeared in the Xiang'er commentary to the Laozi. Prior to this commentary, historiographical works only mentioned a "Way of Huang-Lao." For example, the "Biography of Huangpu Song" in the History of the Later Han states:Previously, Zhang Jue from Julu had called himself Perfect Master of Great Excellence. He served the Way of Huang-Lao.

SummaryIn 1684, during the Edo period (1603–1868), the imperial court of Japan passed a reform act that resulted in a new almanac called the Jôkyô almanac. This was the first reform in more than eight hundred years, and marked a departure from the past practice of adopting almanacs from China. Yet, the reform was complicated, and it was achieved after decades through the efforts of Shibukawa Harumi (1639–1715). How was the reform accomplished, and why was it significant? In this study, (...) I will focus on Harumi's role in the reform. I propose to examine the reform as the culmination of a process deeply linked to Harumi's political connections and his intellectual growth especially in the field of calendrical sciences. I will show that this approach of looking at the reform by analyzing different aspects of Harumi's life has implications for understanding trends in society in seventeenth-century Japan. First, despite the ban on Christianity, intellectuals like Harumi assimilated European sciences in unique ways. Second, Harumi's activities exemplified how intellectual ties were increasingly embedded within political networks. Overall, I will argue that the reform of the almanac, viewed as a process surrounding the core figure of Harumi, was driven by scientific goals and personal ambitions. (shrink)

Procrastination describes a ubiquitous scenario in which individuals voluntarily postpone scheduled activities at the expense of adverse consequences. Steel pioneered a meta-analysis to explicitly reveal the nature of procrastination and sparked intensive research on its demographic characteristics. However, conflicting and heterogeneous findings reported in the existing literature make it difficult to draw reliable conclusions. In addition, there is still room to further investigate on more sociodemographic features that include socioeconomic status, cultural differences and procrastination education. To this end, we performed (...) quantitative sociodemographic meta-analyses to fill this gap. It was found that the general tendency and academic procrastination tendency of males were stronger than females. No significant effects of differences in socioeconomic status, multiculturalism, nationality, family size, and educational background were found to affect procrastination tendencies. Furthermore, it was noteworthy that the gender differences in procrastination tendencies were prominently moderated by measurements, which has a greater effect on the Aitken Procrastination Inventory than on the General Procrastination Scale. In conclusion, this study provides robust evidence that males tended to procrastinate more than females in general and academic profiles, and further indicates that procrastination tendencies do not vary based on sociodemographic situations, including socioeconomic status, multiculturalism, nationality, family size, and educational background.

Marx and Rawls seems to have a very different concept of justice. Marx argued that the concept of justice functions in the performance of the dominant ideological mode of production required for the conduct, as universally binding legal code. Rawls is argued that justice is the first virtue of social institutions, its law may be recognized by all such people: they are fair and reasonable to discuss the issue is how to equitably divide among themselves the burden of social cooperation (...) and interests. Although embodied in Marx and Rawls an important difference between the various positions still exist, but I believe that the concept of justice is obviously two different positions, is able to reconcile. Despite the different effects of Hegel and Kant, Marx and Rawls's view can still show the same place. In a clear political concept of justice, Rawls believes that acceptable principles of justice, must be in the social system can be implemented. This led to his "Kantian constructivism", close to Hegel's view, at this point, Marx laid him on the universal, social rejection of a priori principles of justice. I believe that both Marx and Rawls are asked, and what can be seen as a social system to achieve the principles of justice as fairness. However, during which there are two important differences. First, Marx's vision, seems to be a Hume and Rawls beyond the so-called "environmental justice" society, while Rawls , the social environment beyond the justice is utopian. Secondly, Marx believed that, as the social basis of market relations should be exceeded, because the relationship between these markets to include the producers of natural and social process of production of the products of labor and social alienation. Although environmental justice in the society beyond the market's demise may be, Rawls was declared to be a just solution in the competitive demands of any society, the demise of the market are not. I believe that, if Marx's rejection of the market, as a fundamental denial "commodity fetishism", then the position of Marx and Rawls will be able to reconcile. The author concludes that, in addition to Marx's concept of the future classless society with the ideal ingredients, capitalism and the market in the concept of justice, Marx and Rawls's position is very close. Man and Raids appear to have quite different views at justice. Marx claims that the concept of justice functions ideologically to represent conduct required by the prevailing mode of production as universally binding imperatives. Rawls claims that justice is the first virtue of society, whose principles may be agreed to by all persons who impartially and rationally deliberate on the issue of fairly dividing the burdens and benefits of social cooperation. I argue that these apparently different positions on justice can be reconciled, although important differences between the standpoints of Marx and Rawls remain. Despite the differing influences on them of Hegel and Kant, the views of Marx and Rawls can be shown to converge. In proposing an explicitly political conception of justice, Rawls argues that acceptable principles of justice must be realisable in social institutions. This brings his' Kantian constructivism 'closer to the Hegelian view, on which Marx bases his rejection of universal, socially transcendent principles of justice. I argue that both Marx and Rawls can be seen as asking what social institutions can realise principles of justice as fairness. Nevertheless, two important differences remain. Marx seems to envisage a society which transcends the 'circumstances of justice', as specified by Hume and Rawls, whereas Rawls a society beyond the circumstances of justice as utopian. Secondly, Marx claims that market relations should be transcended as the basis of society, since they inherently involve alienation of producers from the social process of production and from the product of their social labour. However, while elimination of markets might be possible in a society that transcends the circumstances of justice, Rawls claims that it is not possible in any society where a fair resolution of competing claims is necessary. I argue that the positions of Marx and Rawls can be reconciled if we take Marx's objection to markets as fundamentally an objection to the 'fetishism of commodities'. I conclude that, apart from the utopian element in Marx's conception of a future classless society, the positions of Marx and Rawls on the justice of capitalism and the market are quite close.

The expanding demands of healthcare necessitate novel methods of increasing the supply of trained professionals to enhance the delivery of care services. One means of doing so is to expand allied health professionals’ scope of practice. This paper explores the ethics of two examples of such expansion in ophthalmology, comparing the widely accepted practice of nurses administering intravitreal injections and the relatively less prevalent optometrists functioning as physician extenders. We conducted a literature review of empirical research into both practices and (...) conclude that nurses administering intravitreal injections are ethically justified. With adequate standardized training, optometrists can also function as primary eye care providers to improve accessibility to eye care. We provide an algorithm for the ethical introduction of innovative expanded allied healthcare. (shrink)

This article highlights the significance of the “Za shuo” 雜說 (Miscellaneous discourses) series for the study of Han Yu’s 韓愈 (768–824) political ideology, which proposes a three-tier system of governance that is made up of the emperor, the feudal lords, and the bureaucrats. The emperor is the pinnacle of the system; he collaborates with his ministers to devise state policies in the inner palace. The feudal lords protect the emperor in the regional areas. The bureaucrats form the machinery of the (...) government and implement its policies. Challenging current scholarship, which treats each of Han Yu’s essays independently, the article proposes a new interpretation of them as a whole It argues that the three essays “Long shuo” 龍說 (Discourse on the dragon), “Yi shuo” 醫說 (Discourse on physicians), and “Ma shuo” 馬說 (Discourse on horses) form an organic unit that provides internally consistent counsel to the ruler for his governance, and that a fourth essay, “Ti Cui Shanjun zhuan” 題崔山君傳 (Foreword to the biography of Cui Shanjun), is likely an interpolation. Through unearthing the true meaning of this series, the article also narrows down its time of composition, which has traditionally been left unspecified. This article also reveals Han Yu’s attitude toward the revived concern over the enfeoffment of princes in medieval China and toward his political ideology, which is not purely Confucian. The article thus is a contribution to the study of both political history and literary creation in the mid-Tang era. (shrink)

This study chooses Chinese athletes as the research object and constructs the overall network of its social support network and discussion network. From the micro-, meso-, and macrolevels of the social network structure, the structure and characteristics of the athlete’s overall social network are analyzed. Through research, we found that there is embeddedness, that is, the relevance, between society support networks, between society discussion networks, and between society support networks and society discussion networks. At the same time, in the athletes’ (...) social support network and social discussion network, some athletes have no contact with other players; they have no “power” in the group as well, so it is difficult to obtain network resources. We also found that there are small-world characteristics in the social network of Chinese professional athletes. The above findings will provide a deeper understanding of the peculiarities of athlete groups and have certain practical significance for improving athletes’ daily training and life management conditions.

Background An increasing number of studies on physicians’ professionalism have been done since the 2002 publication of Medical Professionalism in the New Millennium: A Physician Charter. The Charter proposed three fundamental principles and ten responsibilities. However, most studies were done in developed countries, and few have been done in China. Additionally, few studies have examined the effect of patient-centered hospital culture (PCHC) on physicians’ professionalism. We aimed to investigate physicians’ medical professionalism in public hospitals in China, and to assess mediating (...) effect of professional attitudes in the relationship of PCHC with professional behaviours. Methods Self-administered questionnaires including professional attitudes (20 items) and behaviours (10 items) survey and PCHC scale (22 items) were given to clinical physicians in five public hospitals, China. The mediating effect of professional attitudes in the relationship of PCHC with professional behaviours was tested. Result 232 valid questionnaires were collected. More than 90% (208) respondents agreed with 15 of 20 specific statements on medical professionalism. As for the responsibility of improving quality of care, 54 (23%) respondents disagreed with reporting of incompetent colleagues and as for the responsibility of maintaining professional competence, 49 (21%) disagreed with recertification. More than 185 (83%) respondents reported that they sometimes, usually, or always showed the four positive behaviours on the questionnaire, and 173 (77%) reported that they never showed the six negative behaviours. Mediating effect analysis revealed that two dimensions of PCHC (i.e. value/institution culture and behaviour/material culture) had a significant positive impact on physicians’ professional behaviour, and professional attitude played a complete mediation role between them, but another dimension of PCHC (i.e. negative evaluation of hospital) directly affected professional behaviour without influencing professional attitude. Conclusion Chinese physicians showed positive professional attitudes and behaviours. Different dimensions of PCHC affected physicians’ attitudes and behaviours in different ways. (shrink)
