ObjectiveTo investigate the effects of cell phone dependence on mental health among undergraduates during the COVID-19 pandemic and further identify the determinants that may affect their mental health in China.MethodsThe data were collected from 602 students at a medical school in Shanghai via an online survey conducted from December 2021 to February 2022. The Mobile Phone Addiction Index and Depression Anxiety Stress Scale were applied to evaluate CPD and mental health, respectively. Independent sample t-test and one-way analysis of variance were (...) employed to compare the means of continuous variables among categorical groups. Correlations between continuous variables were detected using Pearson's correlation analysis. Univariable and multivariable logistic regressions were employed to identify the determinants of mental health.ResultsAmong the 402 eligible students, 73.88% were women with an average age of 20.19 ± 2.36 years. On average, the DASS score was 32.20 ± 11.07, the CPD score was 36.23 ± 11.89, and the cell phone use duration was 7.67 ± 3.61 h/day. CPD was found to have a negative effect on mental health among college students in Shanghai. Additionally, cell phone use duration, age, being senior students, faculty-student relationship, insomnia, tobacco use, obesity, and life satisfaction were clarified as contributing factors to mental health among college students.ConclusionHigh degree of CPD could have a negative effect on college students' mental health, which might lead to some psychological problems. Appropriate actions and effective interventions are highly needed to prevent severe psychological injuries among college students in China. (shrink)

In order to provide a unified framework for studying non-commutative algebraic logic, Rump and Yang used three axioms to define quantum B-algebras, which can be seen as implicational subreducts of quantales. Based on the work of Rump and Yang, in this paper we shall continue to investigate the properties of three axioms in quantum B-algebras. First, using two axioms we introduce the concept of generalized quantum B-algebras and prove that the opposite of the category GqBAlg of generalized quantum B-algebras is (...) equivalent to the category LogPQ of logical pre-quantales, but we can not prove that pre-quantales can be used as the injective objects in GqBAlg. Next, we use one axiom to propose the concept of C-algebras and show that a C-algebra is a group if and only if each of its elements is dualizing. Further, by dualizing elements of a C-algebra X, we can define different binary operations on X such that X is a moniod. Finally, we by the Zig–Zag relation discuss some properties of quantum B-algebras. (shrink)

Angle is an important concept in geometry. Young children have difficulty separating angle size from other dimensions such as the length of angle sides, perhaps due to whole-object bias in word learning. The present study used the pre-test–training–post-test design to investigate the effectiveness of two ways of separating angle from angle size in 3–6-year-old Chinese preschoolers. A total of 228 children were given a pre-test and 219 of them failed the crucial test. 168 of the 219 children were present at (...) school during the training phase and were randomly assigned to three groups: the “toma” group, which received training to call the whole angle figure as “toma” and angle size as angle size; the “angle/angle size” group, which received the training of separating “angle” from “angle size”; and the control group, which used “angle size” alone to represent both the overall angle figure and angle size. Results showed that the “toma” group improved significantly more than the other two groups, the latter of which did not differ from each other. These results suggest that it is insufficient to have two separate words/phrases for children to learn to differentiate angle from angle size, perhaps due to their shared usage of the word angle. Instead, the use of a novel term is necessary and sufficient to improve learning. Implications for preschool education are discussed. (shrink)

Teachers' adaptive expertise has received increasing attention in the current English as foreign language teaching field, however, it has seldom been examined with adaptive practices by teachers in on-going classes among existing literature. Adopting a mixed-method design with data triangulation, this study was conducted to explore the complexity of teachers' adaptive expertise and adaptive teaching practices that an EAP writing teacher demonstrated in academic writing courses, from a Complex Dynamic Systems Theory perspective. Semi-structured interviews, classroom observations, and questionnaires were arranged (...) to collect qualitative and quantitative data from an EAP writing teacher and 43 EFL learners in a Chinese university. Thematic analysis and SPSS were mainly used in the current work for data analysis. Our findings confirmed the complexity of TAE and ATP with specific features of non-linearity, interconnectedness, and self-organization, which are classic CDST characteristics; the TAE evolved with meta-cognitive, cognitive, affective and social components that are intertwined and contributed to the teacher's adaptive teaching practices in her academic writing course; being facilitated by TAE, the teacher's adaptive teaching practices significantly enhanced EFL learners, learning motivation of academic writing and their learning efficiency. Findings of the current work pave the way for future studies in researching TAE and ATP with a thorough consideration of language teachers, students and contexts from the CDST perspective. Moreover, pedagogical contributions are highlighted through the detailed examinations of the EAP writing teacher's ATP, including the class design, teaching plans, and methods, which would be fruitful for the development of tertiary EAP writing research.

This paper is devoted to develop a nonlocal and time-delayed reaction-diffusion model for HIV infection within host cell-to-cell viral transmissions. In a bounded spatial domain, we study threshold dynamics in terms of basic reproduction numberR0for the heterogeneous model. Our results show that ifR0 1, virus will persist in the host environment.

Abstract:A number of philosophers of language have proposed that people do not have conceptual access to‘bare particulars’, or attribute‐free individuals (e.g. Wiggins, 1980). Individuals can only be picked out under some sortal, a concept which provides principles of individuation and identity. Many advocates of this view have argued thatobjectis not a genuine sortal concept. I will argue in this paper that a narrow sense of‘object’, namely the concept of any bounded, coherent, three‐dimensional physical object that moves as a whole (Spelke, (...) 1990) is a sortal for both infants and adults. Furthermore,objectmay be the infant's first sortal and more specific sortals such ascupanddogmay be acquired later in the first year of life. I will discuss the implications for infant categorization studies, trying to draw a conceptual distinction between a perceptual category and a sortal, and I will speculate on how a child may construct sortal concepts such ascupanddog.

In any given historical period, the fate of human beings is determined directly by their modes of existence and their ways of understanding to the future. In our time, the process of modernization leaves us uncertain about the future. This situation of uncertainty gives a new way of philosophizing and understandingphilosophy that must be appropriate to our new way of experiencing the future. We must recognize that the future has its own reality: that it transcends us and is also impact (...) within us, and that it is inherently unpredictable. Therefore, the mission of philosophy in our time is to embody this new way of experiencing the future and help people to see the future from the future. This way of living does not rest on the assumption that history has a given aim, but instead seeks to buildthe future that focuses on dialogue among people with different viewpoints. (shrink)

The existing scholarship has developed six main explanations to account for the success of the Chinese Revolution, which has been anomalous for major paradigms derived from cross-national comparisons. Methodologically, we use a social geographical approach to test these existing explanations systematically by constructing and analyzing a unique dataset of Communist growth in 93 counties in the three most contested provinces during its most pivotal period of ascendence. Theoretically, we advance and test an alternative perspective, based on the groundwork of Tocqueville (...) and Fei Xiaotong, that integrates the state-centric theory, elite theory, and cultural analysis. Our perspective emphasizes the interplay between state centralization and local elite structure, which leads to intensified state extraction and local elite fracturing, thus creating favorable conditions for revolution. The quantitative analysis strongly supports the importance of the Japanese invasion but provides limited support for many other conventional explanations. The analysis largely confirms the Tocqueville-Fei perspective on state centralization, elite fracturing, cultural change, and revolution. The findings are buttressed by a detailed case study of Lianshui County. The study unveils a common structural challenge that a modernizing state faces in an agrarian status society, to recreate its political legitimacy while disrupting local elite structure. It also sheds historical light on the evolution of state-society relationship through the Chinese Revolution. (shrink)

Critical Discourse Analysis has excelled with its functional and ideological analysis of socio-political texts. Its capacities and achievements notwithstanding, this tradition is constituted of Western concepts, values, ways of thinking, analytic tools and topics of interest; such becomes problematic when universalised and globalised in international academic discourse. It is against this backdrop of cultural and intellectual tension that a culturally conscious and critical paradigm of discourse and communication research is emerging: Cultural Discourse Studies. It is manifested in the forms of (...) participation by searchers from the Developing World in significant proportions, development of locally grounded, globally minded research frameworks; and a growing multicultural awareness in the discipline. Inspired by Third World experiences, aspirations and scholarships on the one side and drawing on culturally critical insights in the human and social sciences on the other side, this multicultural scholarship endeavours to deconstruct ethnocentrism, construct culturally diversified modes of research and propel intercultural dialogue and debate in the discipline, all with a view to enhancing human cultural coexistence, harmony and prosperity. One exemplar of this new trend is Chinese Discourse Studies, characterised by a holistic philosophy, equilibrium and discrepancy theory, all-encompassing methodology and development-minded research agenda.

Lower plasma levels of high-density lipoproteins in adolescents with type 2 diabetes have been associated with a higher pulse wave velocity, a marker of arterial stiffness. Evidence suggests that HDL proteins or particle subspecies are altered in T2D and these may drive these relationships. In this work, we set out to reveal any specific proteins and subspecies that are related to arterial stiffness in youth with T2D from proteomics data. Plasma and PWV measurements were previously acquired from lean and T2D (...) adolescents. Each plasma sample was separated into 18 fractions and evaluated by mass spectrometry. Then, we applied a validated network-based computational approach to reveal HDL subspecies associated with PWV. Among 68 detected phospholipid-associated proteins, we found that seven were negatively correlated with PWV, indicating that they may be atheroprotective. Conversely, nine proteins show positive correlation with PWV, suggesting that they may be related to arterial stiffness. Intriguingly, our results demonstrate that apoA-I and histidine-rich glycoprotein may reverse their protective roles and become antagonistic in the setting of T2D. Furthermore, we revealed two arterial stiffness-associated HDL subspecies, each of which contains multiple PWV-related proteins. Correlation and disease association analyses suggest that these HDL subspecies might link T2D to its cardiovascular-related complications. (shrink)

When we say “I know why he was late”, we know not only the fact that he was late, but also an explanation of this fact. We propose a logical framework of “knowing why” inspired by the existing formal studies on why-questions, scientific explanation, and justification logic. We introduce the Kyi\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{\mathcal {K}}{}\textit{y}}_i$$\end{document} operator into the language of epistemic logic to express “agent i knows why φ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} (...) \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varphi $$\end{document}” and propose a Kripke-style semantics of such expressions in terms of knowing an explanation of φ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varphi $$\end{document}. We obtain two sound and complete axiomatizations w.r.t. two different model classes depending on different assumptions about introspection. Finally we connect our logic with justification logic technically by providing an alternative semantics and an in-depth comparison on various design choices. (shrink)

Due to the differences of languages, “ontology” in its original Western sense had not been conceptualized in ancient China. The most prominent and unique feature of Confucian philosophy in early ancient China is “Zhongtaology” instead of “ontology”. Zhongtaology is the philosophical inquiring for the way of “Zhong”, which is based on all the primordially related semantic meanings embodied in the Chinese character “zhong”. Zhongtaological philosophy indicates an association between human beings and their world, a coincidence between subjectivity and objectivity, a (...) harmony of internal world and external world, an intersubjective perspective between self and others, an equilibrium among different ideas and divergences. Zhongtaology advocates inclusiveness and harmony when dealing with conflicts and contradictions. The rich historical and cultural background of Zhongtaology enriches it with profound philosophic significance, and makes it a general philosophical methodology of Confucianism. Zhongtaology not only provides a Confucian approach to some fundamental ontological and epistemological issues, a philosophical foundation for establishing ethical norms, moral standards, social justice and political principles, but also provides an angle to understand certain aspects of Chinese way of life.

Appraisal is the way language users express their attitude towards things, people, behaviour or ideas. In the last few decades, significant achievements have been made in Appraisal Theory research, yet little attention has been paid to appraisal in scientific texts, especially in relation to the contrast to how it is applied in English and Chinese. This title examines the similarities and differences of Appraisal systems in English and Chinese scientific research articles. Using a self-constructed corpus of scientific research articles, the (...) authors make cross-linguistic comparisons in terms of the quantity and distribution patterns of categories of appraisals. They creatively categorise articles into theoretical scientific research articles and applied studies and discover that for both languages, each genre can have its own favorite mode of distribution for the realization of appraisal systems. In addition, this research helps appraisal theory systems to become more explicit, specific, and more applicable for the analysis of scientific research articles. Students and scholars of applied linguistics, comparative linguistics and corpus linguistics will find this an essential reference. (shrink)

Hui Shi (370-310B.C.E.?) is a unique one among the pre-Qin scholars. The object and orientation of his scholarship emphasized on “chasing after the materials” or the research for objective knowledge of natural things. He shows a tendency of tolerating and advocating diversity and variety, and intentionally pursuing new and unusual ideas. In certain degree he judges the value of knowledge by its truthfulness rather than its usefulness. As pointed out by Wing-tsit Chan, Hui shi represents a “tendency in ancient China (...) toward intellectualism for its own sake”. (shrink)

As a tool for analyzing time series, grey prediction models have been widely used in various fields of society due to their higher prediction accuracy and the advantages of small sample modeling. The basic GM model is the most popular and important grey model, in which the first “1” stands for the “first order” and the second “N” represents the “multivariate.” The construction of the background values is not only an important step in grey modeling but also the key factor (...) that affects the prediction accuracy of the grey prediction models. In order to further improve the prediction accuracy of the multivariate grey prediction models, this paper establishes a novel multivariate grey prediction model based on dynamic background values model) and uses the whale optimization algorithm to solve the optimal parameters of the model. The DBGM model can adapt to different time series by changing parameters to achieve the purpose of improving prediction accuracy. It is a grey prediction model with extremely strong adaptability. Finally, four cases are used to verify the feasibility and effectiveness of the model. The results show that the proposed model significantly outperforms the other 2 multivariate grey prediction models. (shrink)

As a non-dualistic but holistic and harmonious way of thinking, Chinese Yin-Yang Thinking can make great contributions to the contemporary dialogue between science and religion, especially in its emphasis on interdependence, mutual complementarity, and mutual transformation. It can help us understand the complex and multifaceted relationship between science and religion, and provides a middle way to move beyond the impasse between scientism and religious fundamentalism. This paper explores the following three contributions that Yin-Yang Thinking can make to the contemporary dialogue (...) between science and religion: 1. Yin-Yang Thinking can help deconstruct the dichotomy between science and religion by showing the interpenetration between them; 2. Yin-Yang Thinking can help promote synergy between science and religion by showing how they can complement and learn from each other; 3. Yin-Yang Thinking can help establish a partnership between science and religion in order to create an ecological civilization. The paper also explores the question of why such a valuable philosophical concept has been suppressed in China for almost a century. (shrink)
