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)

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.

In this paper, I provide a framework for accounting for the self, based on a reconstruction of Galen Strawson’s “theory of SESMETs,” or the Pearl view, with Barry Dainton’s continuous consciousness thesis. I argue that the framework I provide adequately accounts for the self and is preferable to solely adopting either Strawson’s or Dainton’s theory. I call my reconstruction the “Necklace” view of the self.

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)

Thomas Aquinas has argued that the passion of hope is the movement of the sensitive appetite and the first of the irascible passion. The first part of the article aims to explore the cause and the mechanism of the passion of hope, and tries to clarify the relationship between the passion of hope and the perception. In human beings, it is possible that the passion of hope is caused by false judgement of the perception, which will lead to the result (...) of false hope. In Aquinas’s argument, the problem of false hope could be solved through the moral virtue and the prudence. In the second part of this article, the aim is to analyse how the virtue of magnanimity, humility and the prudence work impact on the passion of hope and perfect it.Contribution: This research concentrates on the topic of the passion of hope of Thomas Aquinas, and provides a new perspective on the understanding of the relationship between the passion and the virtue.

The subject of this work is the worldview of subculture and its complex interaction with the elements and structure of these groups. To do this, various types of subcultures are analyzed in detail in order to identify their unique ideological features and characteristics. The main purpose of the research is to find links between the worldview of subcultures and their structural elements, as well as to understand the impact of these links on socio-cultural processes. By analyzing these issues, the study (...) seeks to expand our understanding of subcultural dynamics and their place in the modern sociocultural context. The results of this work can be useful for further research in the field of anthropology, sociology, cultural studies, as well as for the development of practical strategies for managing and supporting subcultural communities. To achieve the goals of the study, an anthropological analysis of subcultures is used, which includes an analysis of synchronous and diachronic aspects of the subcultural worldview, as well as comparative analysis. The scientific novelty of this work is manifested in a deep and comprehensive analysis of the diversity of types of worldview representation in various subcultures and their impact on a wide range of socio-cultural processes. The analysis presented in the study reveals unique aspects of the subcultural worldview and its diverse manifestations, which not only contributes to a deeper understanding of the socio-cultural dynamics of modern society, but also expands our knowledge of the mechanisms of formation and functioning of subcultural communities. The conclusions of this work are important both for academic research in the field of anthropology and sociology, and for practical applications, for example, those aimed at effective management and support of subcultural groups in modern society, including the development of policies and programs that promote inclusivity, cultural diversity and socio-cultural harmony.

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.

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)

In this paper we prove the uncompactness of every stit logic that contains a generalized refref conditional and is a sublogic of the stit logic with refref equivalence, a syntactical condition of uncompactness that covers infinitely many stit logics. This result is established through the uncompactness of every stit logic whose semantic structures contain no chain of busy choice sequences with cardinality , where is any natural number . The basic idea in the proof is to apply the notion of (...) companions to stit sentences in finding busy choice sequences in structures, and to make use of a relation between chains of busy choice sequences and generalized refref conditionals in connecting the two conditions of uncompactness mentioned above.
