ObjectiveWe conducted the following cross-sectional study to comprehensively assess the anxiety among Chinese international students who studied online during the COVID-19 pandemic and its influencing factors.MethodsQuestionnaires were distributed through “Sojump,” and a total of 1,090 valid questionnaires were collected. The questionnaire was divided into two parts: general situation and anxiety assessment of students. The former used a self-made questionnaire, and the international general GAD-7 scale was used to measure anxiety. Chi-square test was used to analyze the differences between groups, and (...) logistic regression analysis was performed for the factors with differences.ResultsAnxiety was found in 707 of 1,090 international students. Chi-square test and multivariate Logistic regression analysis showed that the incidence of anxiety was higher in the group under 22 years of age than in the group over 22 years of age ; International students living in big cities had a higher incidence of anxiety than those living in rural areas ; international students who socialized 3 times or less monthly had a higher incidence of anxiety than those who socialized more than 3 times per month ; international students who expected purely online teaching had a higher incidence of anxiety than those who expected purely offline teaching or dual-track teaching ; international students with a subjective score of online learning experience of 6 or less had a higher incidence of anxiety than those with subjective scores of more than 6. However, gender, emotional status, BMI, major of study, vaccination status, and degree type had no significant difference in the incidence of anxiety among international students who studied online during the COVID-19 pandemic.ConclusionDuring COVID-19, international students who were younger, came from big cities, had low social frequency, expected purely online teaching, and had poor experience of online classes were risk factors for anxiety during online classes.

It will be settled out for the open problem of designing an r-order finite-time state observer for reaction-diffusion genetic regulatory networks with time-varying delays. By assuming the Dirichlet boundary conditions, aiming to estimate the mRNA and protein concentrations via available network measurements. Firstly, sufficient F-T stability conditions for the filtering error system have been investigated via constructing an appropriate Lyapunov–Krasovskii functional and using several integral inequalities and convex technique simultaneously. These conditions are delay-dependent and reaction-diffusion-dependent and can be checked by (...) MATLAB toolbox. Furthermore, a method is proposed to design an r-order F-T state observer, and the explicit expressions of observer gains are given. Finally, a numerical example is presented to illustrate the effectiveness of the proposed method. (shrink)

Language teacher research is conducive to the development of teachers’ teaching skills and professional careers. Thus, many English teacher education programs require student teachers to do research. However, some empirical findings suggest that English as a foreign language student teachers lack research motivation. Consequently, finding suitable interventions to increase their research motivation has become increasingly necessary. In light of the importance of research motivation intervention, this study involved designing an experiment to identify the effect of a value and interest intervention (...) including the sharing of positive research experiences to improve student teachers’ research motivation. Quantitative questionnaires and qualitative semi-structured interviews were used to gather evidence on the change in student teachers’ research motivation during the intervention. The interview data revealed that student teachers’ research motivation was influenced by their belief in the value of research to their teaching practice. The experiment results suggested that student teachers’ intrinsic and extrinsic research motivations both increased after the intervention. However, the intervention was not effective in curbing their failure avoidance tendency. Pedagogical implications of the results are discussed at the end of this article. (shrink)

In the presence of heterogeneity between the randomized controlled trial (RCT) participants and the target population, evaluating the treatment effect solely based on the RCT often leads to biased quantification of the real-world treatment effect. To address the problem of lack of generalizability for the treatment effect estimated by the RCT sample, we leverage observational studies with large samples that are representative of the target population. This article concerns evaluating treatment effects on survival outcomes for a target population and considers (...) a broad class of estimands that are functionals of treatment-specific survival functions, including differences in survival probability and restricted mean survival times. Motivated by two intuitive but distinct approaches, i.e., imputation based on survival outcome regression and weighting based on inverse probability of sampling, censoring, and treatment assignment, we propose a semiparametric estimator through the guidance of the efficient influence function. The proposed estimator is doubly robust in the sense that it is consistent for the target population estimands if either the survival model or the weighting model is correctly specified and is locally efficient when both are correct. In addition, as an alternative to parametric estimation, we employ the nonparametric method of sieves for flexible and robust estimation of the nuisance functions and show that the resulting estimator retains the root- n n consistency and efficiency, the so-called rate-double robustness. Simulation studies confirm the theoretical properties of the proposed estimator and show that it outperforms competitors. We apply the proposed method to estimate the effect of adjuvant chemotherapy on survival in patients with early-stage resected non-small cell lung cancer. (shrink)

A frequent caveat in online dating profiles – “No fats, femmes, or Asians” – caused an LGBT activist to complain about the bias against Asians in the American gay community, which he called “racial looksism”. In response, he was asked that, if he himself would not date a fat person, why he should find others not dating Asians so upsetting. This response embodies a popular attitude that personal preferences or tastes are simply personal matters – they are not subject to (...) moral evaluation. In this paper, I argue, against this popular attitude, that a personal preference like racial looksism is indeed wrong. A preference like racial looksism is wrong because it is an overgeneralization that disrespects individuality by treating people as exchangeable tokens of one type, and such disrespect denies its objects appreciation that their dignity entitles them to. As it turns out, there is on my account a relevant moral difference between racial looksism and simple looksism. (shrink)

Dujiangyan irrigation system of more than 2000 years history is a symbol of originality of Chinese ancestors both in its conception and project mode. It is still working well and benefit Chengdu Plain nowadays while other comparable water conservancy projects of the same or later age have vanished and been forgotten. More than just a world-famous cultural heritage, it shows the harmonious relationship between man and nature. And it also reveals us how to solve problems in the era of economic (...) globalization, such as the constantly silt up of the dams, the exhaustion of the energy and the crisis of the deterioration of ecosystem. The inspirations it gives us range from technology to humanities, from economy to various aspects in social life. In a word, Dujiangyan irrigation system demonstrates the wisdom and creativity of Chinese people and has a universal significance despite the change of time and space. (shrink)

One type of soft-line reply to manipulation arguments, which I call ‘the another-agent reply’, focuses on the existence of some controlling agent and how this can undermine the actor's moral responsibility. A well-known challenge to this type of reply is the so-called ‘machine induction’ case. This paper provides an argument for why ‘machine induction’ presents no real challenge to the another-agent reply. It further argues that any soft-liner who does not leave room for the existence of some controlling agent in (...) their explanation of why manipulation undermines responsibility will face a dilemma. Thus, instead of presenting a challenge to the another-agent reply, ‘machine induction’ actually presents a reason in support of it. (shrink)

This paper is an attempt to improve the practical argument for beliefs in God. Some theists, most famously Kant and William James, called our attention to a particular set of beliefs, the Jamesian-type beliefs, which are justified by virtue of their practical significance, and these theists tried to justify theistic beliefs on the exact same ground. I argue, contra the Jamesian tradition, that theistic beliefs are different from the Jamesian-type beliefs and thus cannot be justified on the same ground. I (...) also argue that the practical argument, as it stands, faces a problem of self-defeat. I then construct a new practical argument that avoids both problems. According to this new argument, theistic beliefs are rational to accept because such beliefs best supply us with motivation strong enough to carry out demanding moral tasks. (shrink)

The authors find East Asians to be holistic, attending to the entire field and assigning causality to it, making relatively little use of categories and formal logic, and relying on "dialectical" reasoning, whereas Westerners, are more analytic, paying attention primarily to the object and the categories to which it belongs and using rules, including formal logic, to understand its behavior. The 2 types of cognitive processes are embedded in different naive metaphysical systems and tacit epistemologies. The authors speculate that the (...) origin of these differences is traceable to markedly different social systems. The theory and the evidence presented call into question long-held assumptions about basic cognitive processes and even about the appropriateness of the process–content distinction. (shrink)

Philosophers debate over the truth of the Doctrine of Doing and Allowing, the thesis that there is a morally significant difference between doing harm and merely allowing harm to happen. Deontologists tend to accept this doctrine, whereas consequentialists tend to reject it. A robust defence of this doctrine would require a conceptual distinction between doing and allowing that both matches our ordinary use of the concepts in a wide range of cases and enables a justification for the alleged moral difference. (...) In this article, I argue not only that a robust defence of this doctrine is available, but also that it is available within a consequentialist framework. (shrink)

The relationships between age and the life-supporting treatments use, and between gender and the life-supporting treatments use are still controversial. Using extracorporeal membrane oxygenation as an example of life-supporting treatments, the objectives of this study were: to examine the relationship between age and the extracorporeal membrane oxygenation use; to examine the relationship between age and the extracorporeal membrane oxygenation use; and to deliberate the ethical and societal implications of age and gender disparities in the initiation of extracorporeal membrane oxygenation. This (...) is a population-based, retrospective cohort study. Taiwan’s extracorporeal membrane oxygenation cases from 2000 to 2010 were collected. The annual incidence rate of extracorporeal membrane oxygenation use adjusting for both age and gender distribution for each year from 2000 to 2010 was derived using the population of 2000 as the reference population. The trend of extracorporeal membrane oxygenation use was examined using time-series linear regression analysis. We conducted joinpoint regression for estimating the trend change of extracorporeal membrane oxygenation use. The trends of extracorporeal membrane oxygenation use both for different gender groups, and for different age groups have been significantly increasing over time. Men were more likely to be supported by extracorporeal membrane oxygenation than women. Women’s perspectives toward life and death, and women’s perception of well-being may be associated with the phenomenon. In addition, the patients at the age of 65 or older were more likely to be supported by extracorporeal membrane oxygenation than those younger than 65. Family autonomy/family-determination, and the Confucian tradition of filial piety and respecting elders may account for this phenomenon. This study showed gender and age disparities in the initiation of extracorporeal membrane oxygenation use in Taiwan, which may be accounted for by the cultural and societal values in Taiwan. For a healthcare professional who deals with patients’/family members’ medical decision-making to initiate life-supporting treatments, he/she should be sensitive not only to the legality, but also the societal and ethical issues involved.

Within the framework of pragma-dialectics, this paper analyzes the use of dissociations in the spokespersons’ replies at the press conferences held by the Chinese Ministry of Foreign Affairs between 2015 and 2017. As shown in the research results, to cut down the authority of their opponents in criticizing China and to convince the international general public of the Chinese standpoints, four subtypes of dissociation are used, which can be differentiated as: “distorted” Term I versus “authentic” Term II, “ambiguous” Term I (...) versus “univocal” Term II, “broadened” Term I versus “exact” Term II, and “narrowed” Term I versus “exact” Term II. The strategic maneuvering carried out by the spokespersons in confronting their immediate opponents by means of the various subtypes of dissociation is in the first place directed at their primary audience, i.e. the international general public. To make a convincing case, in using dissociations the spokespersons not only adapt in their strategic maneuvering to the demands of their primary audience but also in their selection from the topical potential and the presentational devices.

This article explores the moral permissibility of sweatshop boycotts. We build explicitly on Tomhave and Vopat’s (2018) framework for evaluating the moral permissibility of boycotts in general for the specific case of sweatshop labor. We argue that sweatshop boycotts are more likely to be morally justified when targeting forced labor compared to free labor and we explore the relevant moral tradeoffs associated with boycotts of free labor sweatshops. We analyze the morality of three cases of sweatshop boycotts—Indonesia in the 1990s, (...) Bangladesh following the 2013 Rana Plaza disaster, and the Uyghur region in China—and then discuss how insights from these cases might provide a model to guide activists and business ethicists in analyzing the morality of other sweatshop boycotts.

Of the three powers—Wei, Shu, and Wu—that divided China for the better part of the third century, Wei has received the most attention in the standard literary historical accounts. In a typical book of Chinese literary history in any language, little, if anything, is said about Wu and Shu. This article argues that the consideration of the literary production of Shu and Wu is crucial to a fuller picture of the cultural dynamics of the Three Kingdoms period. The three states (...) competed with one another for the claim to political legitimacy and cultural supremacy, and Wu in particular was in a position to contend with Wei in its cultural undertakings, notably in the areas of history writing and ritual music. This article begins with an overview of Shu and Wu literary production, and moves on to a more detailed discussion of Wu’s cultural projects, both of which were intended to assert Wu’s legitimacy and cultural power vis-à-vis Wei and Shu’s claims to cultural and political orthodoxy. Ultimately, this article implicitly asks the question of how to write literary history when there is scant material from the period under question, and suggests that we perform textual excavations and make use of what we have to try and reconstruct, as best as we can, what once was. A good literary history of the Chinese medieval period, the age of manuscript culture and that of heavy textual losses and transfigurations, should be written with the awareness of the incomplete and imperfect nature of the data we do have, and incorporate the phenomenon of textual losses and transfigurations as well as some reflections on the underlying reasons into its narrative and critical inquiry.

Reviewing a recent book about early medieval Chinese geographical writings, this essay asks what sort of historical contextualization is needed for historical study, and suggests looking at multiple factors, including the material conditions of textual production, that may be responsible for the proliferation of texts. It cautions against embracing a single story to account for a long historical period, especially if that story fits our modern concerns too neatly; even more importantly, we have to allow the primary sources to take (...) the lead, rather than looking for and presenting only evidence that serves a particular agenda.

A cross-generic examination of the discursive representations of a changing rela- tionship to a specific subcategory of things that are observable in writings from early to medieval China, this essay suggests that these representations denote the appearance of a culture of sentimentality about old, worn-out things at the turn of the ninth century. This culture of sentimentality indicates a deep-seated anxiety about the blurred boundary, on a conceptual and ideological level, between humans and things, and bespeaks the complex dynamics in (...) the relationship of self and other at a time of profound cultural and intellectual changes, in which the textual representations of dilapidated ordinary things of daily life participated. It anticipates and yet remains profoundly different from Northern Song antiquarianism, thus showing gaps and fissures in the neat, familiar teleological narrative of the “Tang-Song transition.”.

Abstract:The most important themes of Wang Lü's painting theory are the "true self" and the "true thing." One reason this topic has not received sufficient attention is that the original text was altered. This article aims to correct and reinterpret the text. After textual research and interpretation, Wang Lü's paintings and painting theory have been reevaluated. This article also responds to some difficult topics such as the relationship between "form" (ᔶ) and "meaning" (ᛣ) and between "following" (ᕲ) and "not following" (...)

Using pure statistical evidence about a group to judge a particular member of that group is often found objectionable. One natural explanation of why this is objectionable appeals to the moral notion of respecting individuality: to properly respect individuality, we need individualized evidence, not pure statistical evidence. However, this explanation has been criticized on the ground that there is no fundamental difference between the so-called “individualized evidence” and “pure statistical evidence”. This paper defends the respecting-individuality explanation by developing an account (...) of what it means to respect individuality. It combines an idealistic account of respecting individuality and a prioritization account of respecting individuality, and offers a principled way to distinguish individualized evidence from non-individualized evidence.

A result from a standard linear model course is that the variance of the ordinary least squares (OLS) coefficient of a variable will never decrease when including additional covariates into the regression. The variance inflation factor (VIF) measures the increase of the variance. Another result from a standard linear model or experimental design course is that including additional covariates in a linear model of the outcome on the treatment indicator will never increase the variance of the OLS coefficient of the (...) treatment at least asymptotically. This technique is called the analysis of covariance (ANCOVA), which is often used to improve the efficiency of treatment effect estimation. So we have two paradoxical results: adding covariates never decreases the variance in the first result but never increases the variance in the second result. In fact, these two results are derived under different assumptions. More precisely, the VIF result conditions on the treatment indicators but the ANCOVA result averages over them. Comparing the estimators with and without adjusting for additional covariates in a completely randomized experiment, I show that the former has smaller variance averaging over the treatment indicators, and the latter has smaller variance at the cost of a larger bias conditioning on the treatment indicators. Therefore, there is no real paradox. (shrink)

It has been found in many cases that consumers are prone to exhibit impulsive buying behavior that is manifested as being immediate, emotional, and irresponsible especially under short video scenario. Supported by the customer inspiration theory, this study explores the psychological mechanism underlying impulse purchase in short videos that differentiates the traditional web shopping by the strong sense of presence in short video marketing. On the basis of a questionnaire survey and three laboratory experiments, this study examines the relationship among (...) presence, customer inspiration, and impulse purchase intention. The empirical results point to the fact that social presence, co-presence, and physical presence have significant positive effects on impulse purchase intention, and customer inspiration mediates the effect of social presence, physical presence, and co-presence on impulse purchase intention. Furthermore, it is indicated that social and co-presence have stronger influences on impulse purchase intention than physical presence, thus proving a stronger effect of social factors on impulse purchase intention than physical factors in short video environment. The research results testify the impact of presence on consumer behavior in the upgrading short video marketing and provide valuable reference for marketing strategies to shorten consumers' decision-making time in short video purchase.

As part of a research project on confrontational maneuvering in the spokespersons’ argumentative replies at the regular press conferences of China’s Ministry of Foreign Affairs between 2015 and 2018, this article analyzes, within the framework of Pragma-Dialectics, how the spokespersons declare a standpoint at issue unallowed or indisputable in order to avoid having to resolve a difference of opinion as it is, according to the questioning journalist, presented by their immediate opponents. Starting from the various rationales the spokespersons presuppose to (...) be understood and regarded acceptable by the questioning journalist and the international general public, three subtypes of declaring a standpoint unallowed or indisputable are differentiated: the “Necessity Rationale” subtype, the “Desirability Rationale” subtype, and the “Feasibility Rationale” subtype. The confrontational maneuvering by declaring a standpoint unallowed or indisputable carried out by the spokespersons is directed both at the immediate opponent and at the international general public. However, it is the international general public that the spokespersons primarily intend to convince. For this purpose, they make in all three subtypes of the unallowed or indisputable declaration an effort to adapt their response to their primary audience’s demand by making strategic choices from the available topical potential and the available presentational devices.

For millennia, the basic idea that there is a universal order that connects human beings and the universe has lived on in many cultures. This order has often been expressed in geometric or musical-harmonic terms. From Pythagoras to Kepler, universal scholars were firmly convinced that this order represented the primordial code of all things. This chapter explores a new interdisciplinary perspective that combines the fields of traditional Chinese medicine (TCM), music theory, and Keplerian astronomical insights. By means of corresponding mathematical (...) analyses, it is shown that the energy meridians of the human body correspond to a specific musical-harmonic order, which in turn is inextricably linked to certain relational aspects of the celestial bodies of our solar system. The study represents completely new discoveries in relation to this universal connection. In doing so, it also opens up new levels of understanding and provides new aspects for the further development of the concept of cosmic life. (shrink)

This paper presents an integrated approach to plan smooth path for robots docking in unknown environments with obstacles. To determine the smooth collision-free path in obstacle environment, a tree structure with heuristic expanding strategy is designed as the foundation of path planning in this approach. The tree employs 3D Dubins curves as its branches and foundation for path feasibility evaluation. For the efficiency of the tree expanding in obstacle environment, intermediate nodes and collision-free branches are determined inspired by the elastic (...) band theory. A feasible path is chosen as the shortest series of branches that connects to the docking station after the sufficient expansion of the tree. Simulation results are presented to show the validity and feasibility of the proposed approach. (shrink)

A geometric lattice is the lattice of closed subsets of a closure operator on a set which is zero-closure, algebraic, atomistic and which has the so-called exchange property. There are many profound results about this type of lattices, the most recent one of which, due to Czédli and Schimdt, says that a lattice L of finite length is semimodular if and only if L has a cover-preserving embedding into a geometric lattice G of the same length. The goal of our (...) paper is to offer the following result: a lattice of finite length is semimodular if and only if every cell in L is a 4-element Boolean lattice and the 7-element non-distributive atomistic lattice having 3 atoms is not a cover-preserving sublattice of L.

A total of 944 expressed sequence tags generated 2212 EST loci mapped to homoeologous group 1 chromosomes in hexaploid wheat. EST deletion maps and the consensus map of group 1 chromosomes were constructed to show EST distribution. EST loci were unevenly distributed among chromosomes 1A, 1B, and ID with 660, 826, and 726, respectively. The number of EST loci was greater on the long arms than on the short arms for all three chromosomes. The distribution of ESTs along chromosome arms (...) was nonrandom with EST clusters occurring in the distal regions of short arms and middle regions of long arms. Duplications of group 1 ESTs in other homoeologous groups occurred at a rate of 35.5%. Seventy-five percent of wheat chromosome 1 ESTs had significant matches with rice sequences, where large regions of conservation occurred between wheat consensus chromosome 1 and rice chromosome 5 and between the proximal portion of the long arm of wheat consensus chromosome 1 and rice chromosome 10. Only 9.5% of group 1 ESTs showed significant matches to Arabidopsis genome sequences. The results presented are useful for gene mapping and evolutionary and comparative genomics of grasses. (shrink)
