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)

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.

The extraction process of palm seed oil was optimized. Using palm seed as raw material, oil extraction rate was used as an index. The effects of flash extraction, ultrasonic-assisted extraction, supercritical extraction, and aqueous enzymatic extraction on the yield of palm seed oil were investigated. The extraction methods and technological conditions of palm seed oil were optimized by the orthogonal method on the basis of single factor. The seed oil was analyzed and detected. The results showed that the water enzymatic (...) extraction method was the best, and the optimal extraction conditions were as follows: enzymatic hydrolysis time 16 h, enzymatic hydrolysis temperature 50°C, and enzymatic content 2.0%. The oil yield of palm seed was 16.48%. Conclusion. Water enzymatic extraction process of palm seed oil is reasonable, the active ingredients are rich, and the quality of seed oil is better, providing reference for the development and research of palm seed oil.

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

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

Green housing is a new type of building that advocates energy saving and environmental protection. How to stimulate buyers to buy green housing under the background of high cost is the key problem to guide green consumption. First of all, based on the existing literature, the comment of homebuyers was divided into comment quantity, comment quality, comment titer and evaluator credibility. The psychological distance mediation variable was introduced, and three dimensions of time distance, social distance, and space distance were selected (...) to construct the influence model of homebuyer comment on green housing purchase intention. Meanwhile, the concept model was built, and questionnaires were adopted for empirical analysis. On this basis, considering the long-term purchase behavior of buyers, the influence model of homebuyers' second comment on green housing purchase intention with the Hotelling model was established. The results show that comment quality, comment titer, and the credit rating of the evaluator have a positive effect on green housing purchase intention while comment quantity has no significant effect. Psychological distance plays a mediation role between comment quality, comment titer, the credit rating of the evaluator, and green housing purchase intention while having a mediation effect between comment quantity and green housing purchase intention. In the long-term purchase behavior of green housing, psychological distance plays a greater role than price. At last, some suggestions were proposed. (shrink)

The behavior of somatic stem cells is regulated by their niche. Interaction between hematopoietic stem cells (HSCs) and their niches are a representative model to understand stem cell‐niche interplay. Here, we provide an overview of crosstalk between HSCs and their niches in bone marrow and extramedullary organs following the life journey of HSCs from emergence, development, maturation until aging. We highlight the unique differences of HSC niches in different life stages within various organs focusing on recent literature to propose new (...) speculations and hypotheses. (shrink)

The purpose of this study is to analyze the relationship between psychology and modern art design education in colleges, and to provide the basis for improving the quality of art education in colleges. Based on the relevant theory, the characteristics of educational psychology and art psychology and the correlation between them were analyzed from the angle of art education. According to the characteristics of college students' psychological development, the significance of art psychology-related courses was analyzed. Through the form of questionnaire, (...) a total of 200 students were randomly selected from Xi'an Academy of Fine Arts and Xi'an University of Science and Technology, respectively. A total of 400 questionnaires were issued, and 382 valid questionnaires were recovered. The results show that almost all students in two colleges think pedagogy and educational psychology are the theoretical basis for art teachers, while less than one-third of students in Xi'an University of Science and Technology think that art psychology is the theoretical basis for art teachers. The difference between the students' aesthetic and life values in the two colleges is significant. In the 15 directions of life values, there are significant differences in five directions: spirit—material, enrichment—emptiness, enthusiasm—apathy, hope—despair, and dedication—acceptance. It shows that the psychological and values of college students are changeable, and the educators should pay attention to the education in the related fields of psychology. This exploration was conducted based on educational psychology, which is of great significance for improving the educational level of art psychology in colleges and enable students to form correct aesthetic standards and life values.

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

Chinese international students constitute the largest proportion of overseas students in several English-speaking countries such as the UK and New Zealand. Little research has been done concerning those undertaking doctoral study. This qualitative study explores how Chinese overseas doctoral students become involved in church communities and how some of them convert to Christianity in New Zealand. In-depth interviews were conducted with nine Chinese doctoral students from different social backgrounds. Five of these reported varying degrees of interest in and commitment to (...) Christianity. Their narratives revealed that their conversion was a gradual and complex process as a result of the interplay between habitus, agency and contextual factors. These findings from a New Zealand context provide insights into non-academic experience of Chinese international students, particularly their religious experience. (shrink)

Aristotle and Xunzi on Shame, Moral Education and the Good Life is the first major work that takes two philosophers from the ancient Greek and early Chinese traditions to stimulate discussion of an interdisciplinary nature on the rich and complex topic of the emotions, in particular shame. It features sophisticated comparative analysis of the Greek and Chinese texts while bringing the ancient materials to bear on modern controversies such as the role of shame in moral education and social cohesion. Despite (...) fundamental differences in their social-historical and intellectual backgrounds, Aristotle and Xunzi bear striking similarities in several respects: their concept of humans as essentially members of communities, as having a unique set of characteristics that set them apart from other living things, and as beings in need of moral training to fulfil their potential and become integrated into a well-ordered society. The two philosophers' discourses on shame reveal important insights into their ideals of human nature, moral education and the good life. This book tackles directly the methodological problems that are relevant to anyone interested in cross-cultural comparisons and organises discussion of the ancient sources in such a way as to facilitate a thorough integration of perspectives from the cultural traditions concerned. This approach provides sufficient focus to allow for detailed textual analysis while giving scope for making constant connections to the broader comparative questions at issue. (shrink)

In this paper, I explore an intriguing view of definable numbers proposed by a Cambridge mathematician Ernest Hobson, and his solution to the paradoxes of definability. Reflecting on König’s paradox and Richard’s paradox, Hobson argues that an unacceptable consequence of the paradoxes of definability is that there are numbers that are inherently incapable of finite definition. Contrast to other interpreters, Hobson analyses the problem of the paradoxes of definability lies in a dichotomy between finitely definable numbers and not finitely definable (...) numbers. To bypass this predicament, Hobson proposes a language dependent analysis of definable numbers, where the diagonal argument is employed as a means to generate more and more definable numbers. This paper examines Hobson’s work in its historical context, and articulates his argument in detail. It concludes with a remark on Hobson’s analysis of definability and Alan Turing’s analysis of computability. (shrink)

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

대부분의 연구자들은 주염계의 「태극도설」에 대한 주자의 해석서인 「태극해의」가 이기론을 기반으로 이루어졌다고 주장한다. 그러나 「태극해의」에서 ‘태극=리’라고 명시적으로 주장한 구절은 찾아볼 수 없으며 체계적인 이기론이 나타나지도 않는다. 이와 같은 사실에 비추어 볼 때에 조선유학자들이 이기론을 사용하여 「태극도설」을 해석한 것은 의미가 있다. 남당은 ‘모두 같은 본연지성’과 ‘모두 다른 기질지성’이라는 기존의 이분법적 성론만으로는 인간과 사물의 차이를 본질적으로, 그리고 명실상부하게 분별할 수 없으며, 인간이 도덕적 주체로서 가지는 고유한 지위를 확보하기 어렵다고 보았다. 이와 같은 문제의식에서 남당은 본연지성을 ‘초형기의 본연지성’과 ‘인기질의 본연지성’으로 나누고, 因氣質의 ‘人性과 物性이 다른 (...) 本然之性’이라는 독창적 개념을 토대로 「태극도설」을 해석하였다. 그리고 이 성론에 기반을 둔 ‘一原分殊’의 논리로 「태극도설」에 통일적인 체계를 부여하였다. 그는 리와 기의 분별을 매우 강조하고 있다. 이 분별의 논리가 인물성동이론에 적용될 때 인/물의 본연지성이 다르며 성인과 범인의 마음이 다르다는 ‘차이’의 이론이 정립된다. 그리고 이를 토대로 ‘차이의 형이상학’이 구축된다. 남당은 이 ‘차이의 형이상학’을 기반으로 「태극도설」을 해석하여 통일적인 체계성을 부여한 것이다. 이와 같은 남당의 해석이 ‘동아시아 유학자들의 「태극도설」 해석사에 있어서 어떠한 위상을 차지하고 있는가’라는 문제는 앞으로 중요한 연구과제가 될 것이다. 성리학의 핵심적 쟁점들은 「태극도설」과 밀접한 관계에 있기 때문이다.

Global justice or the lack thereof has internal connections with global poverty. Global justice is an ideal pursuit of cosmopolitanism, which regards basic human needs as its rightful object. The right to life, from the point of view of global justice, is the most fundamental in the list of Human Rights. International anarchy and the current international economic order, however, cast a utopian shadow on the realization of this right when we consider the de facto institutions and the ostensible goal (...) of impartial love for everyone. Humanitarian aid is another approach to the problem of contemporary global poverty. Its difficulty lies first in people’s different conceptions of obligation and donation. They consider the former as duty while the latter is seen to lie beyond the call of duty. Second, in terms of a correlation between right and duty, since everyone has the right to life, the duty falls accordingly upon organizations or individuals. Meanwhile, donation as duty is not perfect obligation, thus is not compulsory either. Finally, international humanitarian aid is constrained by nationalism and partial love. Hence, in the light of either government or individual, the humanitarian aid approach is beset with challenges. Global justice has gained academic importance worldwide since John Rawls’ later works. By contrast to domestic justice, it is a theory of justice that proposes to include all human beings. Global justice stands for a kind of utopian justice in regard to both the institutional path and the humanitarian aid approach. I shall examine the theory of global justice under these two aspects.
