In this study, we tested a possible mechanism of the association between math anxiety and math achievement: the mediating role of math-specific grit. In Study 1, a sample of 10th grade students completed a battery of personality and attitude questionnaires, and math achievement was indexed by curriculum-based examination scores. Mediation analyses indicated that math-specific grit, but not domain-general grit, mediated the relationship between math anxiety and math achievement. In Study 2, we replicated and extended the above findings with another sample (...) of 11th grade students. Mediation analyses indicated that math-specific grit and math-specific procrastination played sequential mediating roles in the relationship between math anxiety and math achievement. That is, individuals with higher math anxiety were less gritty in math learning, possibly further leading them to be more procrastinated in performing math work, which may finally result in worse math achievement. In summary, the current study provides the first evidence that math-specific grit may mediate the relationship between math anxiety and math achievement. Furthermore, it also demonstrated the value of math-specific grit over domain-general grit in predicting math success, which invites a broader investigation on subject-specific grit. (shrink)

We give a new proof of Friedman's conjecture that every uncountable Δ11 set of reals has a member of each hyperdegree greater than or equal to the hyperjump.

The paper contains some observations on e-complete, precomplete, and uniformly finitely precomplete r. e. equivalence relations. Among these are a construction of a uniformly finitely precomplete r. e. equivalence which is neither e- nor precomplete, an extension of Lachlan's theorem that all precomplete r. e. equivalences are isomorphic, and a characterization of sets of fixed points of endomorphisms of uniformly finitely precomplete r. e. equivalences.

Based on the control-value theory, this study qualitatively investigated the relationship between control-value appraisals, achievement emotions, and English-as-a-foreign-language performance, and explored other antecedents of achievement emotions in addition to control-value appraisals. Data were collected from six Chinese high school students through two semi-structured interviews and one focus group discussion. With thematic analysis, data were analyzed under the framework of the CVT using NVivo 11.0. Results indicate that high perceived control, high perceived extrinsic, and intrinsic values were interactively associated with enjoyment, (...) pride, and hope. Low perceived control, high perceived extrinsic value, and low perceived intrinsic value were interactively associated with fewer positive achievement emotions and more negative achievement emotions like fear. High perceived control, high perceived extrinsic value, and low perceived intrinsic value were interactively associated with fewer positive achievement emotions, and more negative achievement emotions like anguish. Besides, positive achievement emotions were positively associated with EFL performance, while negative achievement emotions were negatively associated with EFL performance. Moreover, factors inside the classroom, factors outside the classroom, and personal factors were found to be the antecedents of achievement emotions in EFL learning. (shrink)

This paper affords a critical and historical reappraisal of Bakhtin’s theory of polyphony. It addresses the issue of the subjectivity of interpretation in the reception and formulation of this highly influential theory in literary semiotics. Following a revaluation of three major patterns of interpretation of polyphony that have emerged in the global field of literary theory since 1929, as well as Bakhtin’s shift in emphasis in 1963, we find that Bakhtin’s theorizing of polyphony, based on his seemingly inconsistent interpretation of (...) Dostoevsky’s novels, was defined by his own subjectivity as well. An obvious consequence of such subjective predispositions in both the reception of Bakhtin’s theory and his own treatment of Dostoevsky’s polyphonic novels is that they have instigated a type of perpetuating availability bias in approaching the theory of polyphony. This revelation is key to understanding the wholeness of the theory of polyphony from a diachronic perspective. By tracing the cultural and intellectual sources of Dostoevsky’s polyphonic creation, this paper attempts to reframe and restore the Bakhtinian idea of polyphony to its fullness, which we believe can be encapsulated in one phrase: harmony without uniformity.

This article challenges the importance and necessity of confidentiality, which are often taken for granted, and questions whether the default promise of confidentiality to all participants, particularly in educational research, could in fact be an unnecessary concern. This article begins by reviewing the difference in the way confidentiality is handled in different fields and the applicability of some underlying assumptions. This is followed by an explanation of why confidentiality is investigated in the sense of anonymity in this article. Then the (...) article draws on an empirical study where original researchers and their original participants were interviewed about their views on anonymity. Lastly, the contradiction between the promises of confidentiality and the recognition of a participant’s contribution is highlighted. The article concludes with a call for more empirical observation and investigation into the importance of confidentiality. (shrink)

In the second half of the 18th century, the naturalistically planted pleasure ground of England came to be known in France as le jardin anglo-chinois. What the French saw as the Oriental connection of the English landscaping revolution has been denied by English garden historians since Horace Walpole. By way of Matteo Ripa's 1724 visit to London, this paper takes a close look at the issues involved and tries to determine not only whether China was involved at all in the (...) initial change of English gardening taste, but also how specific and crucial that involvement was.

Centering on the cultural transformations of China since late 1970s and covering a diverse of topics in the field, this collection of articles presents a multi-dimensional narrative on the dynamics, dilemmas and characteristics involving this giant process.

Due to excessive greenhouse gas emissions, carbon emission-reducing measures are urgently needed. Important emission-reduction measures mainly include carbon trading and low-carbon cost subsidies. Comprehensive consideration of these two policies is a research hotspot in the field of low-carbon technology investment. Based on this background, this paper considers the impact of consumer low-carbon preferences on market demand and the impact of uncertainty in carbon emission-reduction behaviour. We construct a stochastic differential game model with upstream and downstream enterprises based on cost-sharing coordination (...) under a cost subsidy. From a dynamic perspective, this paper researches the optimal equilibrium strategy and evolution characteristics of the joint emission-reduction mechanism in a supply chain. This paper discusses the sensitivity of the parameters and uses numerical simulation to verify the impact of each parameter on the emission-reduction decision-making activities of stakeholders after introducing the cost subsidy. The results show that a cost subsidy policy can promote carbon emission-reduction investment and supply chain profit. Thus, it is important to strengthen technical cooperation and exchange among enterprises. (shrink)

The article shows that Kuhn's concept of incommensurability emphasizes mainly the objective dimension of communication. To the thesis about the incommensurability of the meanings of scientific concepts in competing paradigms, we oppose the idea of a three-dimensional space of communicative dimensions. We supplement the objective dimension of communication, within which the environmental evolutionary selection of the best knowledge is carried out, with equal social and temporal horizons.

Purpose - The high-speed growth of China’s large-scale new economy indicates that innovation has become the most important economic growth pole. The purpose of this paper is to explore the structure and antecedents of the path to innovation, in which we focus on revealing the mediating effect of organizational character. Design/methodology/approach - Considering the indigenous context of China’s new economy, our research divides the innovation into two types: technological innovation and business model innovation. Then, we build a path model to (...) achieve innovation by taking intellectual capital and organizational character as antecedents. Finally, we use structural equation method to measure the path model on the basis of sample data collected by a questionnaire survey. Findings - The results indicate that intellectual capital has a significant positive direct effect on technological innovation, while its direct effect on business model innovation is not significant. As for indirect effects, organization character not only mediate the beneficial effect of intellectual capital on technological innovation, but also mediate the beneficial effect of intellectual capital on business model innovation. In addition, technological innovation is positively affecting business model innovation, and it plays an intermediary role in the path of intellectual capital to business model innovation. Originality/value - This study takes intellectual capital and organizational character as the common antecedents of innovation and breaks down the content of innovation research into technological innovation and business model innovation. Thus, it has established a brand new theoretical analysis framework of dual innovation and enriched the innovation theory. This theoretical framework has important explanatory power for revealing the technological innovation and business model innovation activities carried out by a large number of corporate organizations in the context of China's new economy and the resulting economic boom. Furthermore, it would enlighten new economic organizations to organize innovation activities more effectively and achieve better innovation performance. (shrink)

After the COVID-19 outbreak, the health status of the general population has suffered a huge threat, and the health system has also encountered great challenges. As critical members of human capital in the health sector, medical students with specialized knowledge and skills have positively fought against the epidemic by providing volunteer services that boosted the resilience of the health system. Although volunteer behavior is associated with individual internal motivation, there is sparse evidence on this relationship among medical students, especially regarding (...) potential mechanisms. Therefore, this study had two main objectives: to examine the influence of prosocial motivation of medical students on their VB; and to verify the chain-mediating role of calling and vocation as well as social responsibility in the relationship between PM and VB. Study I: a total of 2454 Chinese full-time medical students were invited to complete an online survey. Data analysis was performed using descriptive statistics, Pearson’s correlation coefficient, and multiple linear regression analysis. The results demonstrated that PM significantly affected VB in medical students ; CV as well as SR chain-mediated the relationship between PM and VB. PM promoted the formation of SR by positively evoking CV of medical students, further resulting in increased VB. Study II: A 28 person qualitative interview was conducted. Qualitative data are added to reduce the limitations of online questionnaires. At the same time, we can also critically study the VB of Chinese medical students during COVID-19. The results showed that there were various reasons for medical students to volunteer in the process of fighting against COVID-19, and the experience of volunteer service and the impact on their future life were different. Lastly, the current findings suggest that fostering volunteerism among medical students requires the joint effort of the government, non-profit organizations, and medical colleges. (shrink)
