Anxiety is one of the most important affective factors affecting college students' foreign language learning. Especially in the Internet age, new teaching ideas and methods bring new load and anxiety to students' psychology. Taking students who attend a college English online course learning as the research object, this paper analyzes the general situation and professional skills of the students' psychological anxiety under the network environment by using the method of investigation and data analysis. It conceives six methods to reduce the (...) students' psychological anxiety according to the reason analysis and summarizes the more effective ways with data mining of another questionnaire. It points out that teachers can advocate the mode of group learning and peer cooperation, strengthen the timeliness and diversity of tests, increase the richness of extracurricular activities, and increase teachers' and students' quality of online teaching and learning to reduce the anxiety of students' foreign language learning in an online teaching environment.

This volume offers a comprehensive overview of the status of the Buddhist tradition in a contemporary and global context. Buddhist experts from several Asian and Western nations address a number of ethical problems from the Buddhist perspective, including medical and environmental ethics, feminism, the social impacts of materialism, and ethnic minorities. All major schools of Buddhism are represented--Mahayana, Theravada, and Vajrayana--as well as a variety of sects such as Ch'an/Zen, Lojong, and Pure Land.

Should you be targeted by police for a crime that AI predicts you will commit? In this paper, we analyse when, and to what extent, the person-based predictive policing (PP) — using AI technology to identify and handle individuals who are likely to breach the law — could be justifiably employed. We first examine PP’s epistemological limits, and then argue that these defects by no means refrain from its usage; they are worse in humans. Next, based on major AI ethics (...) guidelines (IEEE, EU, and RIKEN, etc.), we refine three basic moral principles specific to person-based PP. We also derive further requirements from case studies, including debates in Chicago, New Orleans, San Francisco, Tokyo, and cities in China. Instead of rejecting PP programs, we analyse what necessary conditions should be met for using the tool to achieve social good. While acknowledging its risks, we conclude that the person-based PP could be beneficial in community policing, especially when merging into a larger governance framework of the social safety net.

Most complex real systems are found to have multiple layers of connectivity and required to be modelled as multiplex networks. One of the extremely critical problems is to reduce the congestion and enhance the transfer capacity, especially in real communication networks with a big data environment. A novel and effective strategy to improve traffic and control congestion is proposed by adding edges according to their weights which are defined by the topology structural properties. Furthermore, which layer is more effective when (...) our strategy is applied is discussed based on its topology structure. Adding edges between nodes whose product of multiplex network betweenness is the highest is confirmed to be more effective, particularly in the layer with stronger community structure. Simulation experiments on both computer-generated and real-world networks demonstrate that our strategy can enhance the transfer capacity of multiplex networks significantly, which is in good agreement with our analysis.

This study explored the acceptance of artificial intelligence-based judicial decision-making (AI-JDM) as compared to human judges, focusing on the moral foundations of the cases involved using within-subject experiments. The study found a general aversion toward AI-JDM regarding perceived risk, permissibility, and social approval. However, when cases are rooted in the moral foundation of fairness, AI-JDM receives slightly higher social approval, though the effect size remains small. The study also found that demographic factors like racial/ethnic status and age significantly affect these (...) attitudes. Especially, racial/ethnic minorities showed more social approval in AI-JDM than the racial/ethnic majority (i.e., non-Hispanic whites). These findings show the potential role of machine heuristics in the acceptance of AI-JDM and have practical implications for the implementation of AI in judicial systems, particularly suggesting a cautious approach and underscoring the need to inform the public, especially minority groups, about the limitations and potential biases of AI-JDM.

The logical intuition hypothesis proposes a difference in the strength between logical and heuristic intuitions. The labels of logical and heuristic intuitions are exclusive to conventional reasoning research. This paper reports the result of testing intuition strength using the dot-probe methodology in a novel multiplication paradigm. Here, “logical intuition” and “heuristic intuition” were relabeled as “weaker intuition” (-1 × 5 = 5) and “stronger intuition” (1 × 5 = 5), respectively, to assess the assumptions about the difference in the strength (...) of “Chinese multiplication mnemonics” intuitions. The dot-probe paradigm was utilized in the following experiments to measure attentional bias. This was assessed by calculating the difference in reaction time between incongruent (the target location is opposite to the probe location) and congruent (the target location is the same as the probe location) conditions. Experiment 1 found attentional bias directed attention to the correct answer for both weaker and stronger intuitions. Experiment 2 replicated and extended Experiment 1 with a secondary task to manipulate high and low cognitive loads. Consequently, stronger intuitions were unaffected by cognitive load and participants were biased toward the correct answer, whereas attentional bias for weaker intuitions only occurred in low load conditions. These results revealed that although both intuitions can guide attention, stronger intuition may guide attention bias in a high-load situation due to its robust automation. Our findings extend the logical intuition hypothesis that proposes a difference in the automated strengths of intuitions to mathematical and analytic thinking. (shrink)

This article systematically surveys the history of Anglo-American philosophy in Taiwan since the late nineteenth century. Contrary to conventional wisdom, it argues that pragmatism remained influential given the dominance of continental philosophy in Japanese colonized Taiwan, where the universal values assumed by pragmatists were used to resist the Empire’s ideology, after WWII, immigrated Chinese scholars brought in more novelty to Taiwanese philosophy than the Vienna circle diasporas brought to their Anglo-American counterparts, in which liberal scholars’ emphasis on science and democracy (...) challenged Chiang’s dictatorship and Chinese nationalism, and analytic philosophy thrived with the advance of democratizing in the 1980s, which, in turn, diversified the philosophy in 1990s Taiwan. Accordingly, Anglo-American philosophy was never confined to the academic ivory tower but had positive impacts on Taiwan’s centennial social transformation. (shrink)

As one of the basic manufacturing industries in China, injection molding industry is faced with the problems of low degree of informatization and intelligence, resulting in low production efficiency and high costs. It is urgent to integrate deeply with new generation of information technology to achieve transformation and upgrade. In this paper, an integrative industrial Internet architecture of “integration of intelligent equipment, intelligent production lines, intelligent workshops, intelligent factories, and intelligent formats” was described. The injection molding intelligent control system, the (...) production management, control platform based on the MES system, and other key technologies were researched. Also, the smart factory architecture based on digital twin was established, and the implementation method of the smart factory digital twin system was elaborated. The feasibility and effectiveness of the method had been verified through the industrial application, which provided the technical supports for the injection molding industrial Internet system. Finally, the intelligent manufacturing industrial Internet cloud platform for injection molding industry was prospected. (shrink)

This volume explores the cross-linguistic diversity, and possibly inconsistency, of the span of linguistic means that signal reported speech and thought. The integration of broad linguistic (viewpoint in conversation and narrative) and cognitive (theory of mind and understanding the inner life and thought of others) strategies for handling mixed points of view will be considered.

How do corporate social responsibility (CSR) disclosure and innovation investment co-evolve with organizational forms to affect firm market value? To address this question, we draw on the co-evolutionary perspective and theorize that the contingency effect of CSR reporting is more pronounced for firms with high uncertainty and low legitimacy by comparing start-up firms vs. established firms and privately owned enterprises (POEs) versus state-owned enterprises (SOEs). Moreover, taking a dynamic approach, we propose that the effects of CSR and innovation investment on (...) market value change when the organizational form transitions over time. Specifically, we argue that when start-up firms transitioned to established firms or when POEs were transformed from SOEs, the strengthening effects of CSR reporting become less pronounced. We test our theory using panel data on 2204 Chinese listed firms for the period of 2008–2017. (shrink)

Large-scale social media services have been challenged due to their lack of ethical principles, which has resulted in allegations of user manipulation such as propagation of fake news related to COVID-19 vaccination and biased algorithmic curations that lead to social polarization. We studied current social media community guidelines and conducted a systematic literature review to identify the core values needed for the establishment of guidelines for responsible social media services. Through expert interviews, a framework and guidelines are proposed for each (...) of three areas: protecting privacy, raising awareness, and controlling abuse. We present each set of guidelines with executable principles and relevant design interventions that practitioners can use to offer responsible social media services. Our expert interviews surfaced tensions between the three areas that need to be addressed in developing responsible social media, such as privacy vs. sharing information, pseudonymity vs. safety, and spreading information vs. safety.

The creative thinking and ability of top management team members is important in coping with rapid changes in the external environment and improving the competitive advantage of an organization. This research focuses on the CEO–TMT interface to explain how CEOs influence TMT characteristics, which in turn affects TMT outcomes. Based on social learning theory, this study examines the associations among CEO ethical leadership, TMT cohesion and TMT creativity in a Chinese context using a total of 91 top management teams. To (...) verify the reliability and validity of the constructs, a series of confirmatory factor analyses (CFAs) were run. The results showed that the hypothesized model captured distinct constructs and fits the data well. Multistep regression method was used to test hypotheses. The results indicated that (a) CEO ethical leadership has a positive effect on TMT creativity; (b) TMT cohesion plays a mediating role in the relationship between CEO ethical leadership and TMT creativity; and (c) power distance plays a moderating role in the relationship between CEO ethical leadership and TMT creativity. The greater the power distance, the weaker the positive relationship between CEO ethical leadership and TMT creativity. This study demonstrates the value of CEO ethical leadership and advocates the importance of establishing team cohesion and building a psychologically safe environment to motivate top managers within an organization to share information and knowledge to improve creativity.

In this essay we explore extensive modes of enactive engagement among humans, physical and computational media richer than the modes represented by classical notions of interaction and relation. We make use of a radically material and a potential-theoretic account of event to re-conceive ad hoc, non-pre-schematized activity in responsive environments. We can regard such activity as sense-making via dehomogenization of material that co-articulates subjects and objects.

Building on prior research in Confucianism and business, the current study examines the effects of Confucianism on consumer trust of government involvement with products and company brands. Based on three major ideas of Confucianism – meritocracy, loyalty to superior, and separation of responsibilities – it is expected that consumers under the influence of Confucianism would perceive products from government-involved enterprises to have more desirable attributes and show preference for their company brands. Findings from an empirical study in the Chinese automobile (...) market support the hypotheses. The results suggest that small firms doing business in China would especially benefit from some association with the government. These results also provide managerial implications for enterprises in other countries with a Confucian cultural background. (shrink)

The self-reference effect refers to better memory for self-relevant than for other-relevant information. Generally, the SRE is found in conditions in which links between the stimuli and the self are forged in the encoding phase. To investigate the possibility that such conditions are not prerequisites for the SRE, this research developed two conditions by using two recognition tasks involving abstract geometric shapes. One was the cue-in-encoding condition in which self- and other-cues were presented to construct links with AGSs during the (...) encoding phase, and the other was the cue-in-retrieval condition in which self- and other-cues were presented to construct links with AGSs during the retrieval phase. The SRE was found in both conditions. The findings reveal that self-cues merely presented during the retrieval phase are sufficient to induce the SRE. Links between the stimuli and the self constructed during the encoding phase may not be necessary prerequisites for the SRE. (shrink)

Ironic criticisms in online interactions are very common, but have rarely been examined. Following the concept of (non)propositional irony, this study investigates how online ironic criticisms are produced and responded to. The findings were derived from a mixed-methods analysis of 200 comments and 1,140 responses collected from Weibo. The analysis offers a computer-mediated taxonomy and identifies four subtypes of ironic criticisms, with different realisation forms in each subtype. Responses to negative evaluations are more common in online ironic interactions. Possible motivations (...) for the prevalence of online ironic criticisms are also discussed. The findings shed light on the creativity of ironic criticisms on social media, and suggest the need for an updated definition of ironic criticisms to account for their use in online interactions.

Comparative syllogism is a type of scientific reasoning widely used, explicitly or implicitly, for inferences from observations to conclusions about effectiveness, but its philosophical significance has not been fully elaborated or appreciated. In its simplest form, the comparative syllogism derives a conclusion about the effectiveness of a factor (e.g. a treatment or an exposure) on a certain property via an experiment design using a test (experimental) group and a comparison (control) group. Our objective is to show that the comparative syllogism (...) can be understood as encoding a simulation view of counterfactuals, in that counterfactual situations are conceptual constructs that can be correctly simulated by homogeneous comparison groups. In this simulation view, the empirical data from the comparison groups play an evidential role in the evaluation of counterfactuals and in obtaining counterfactual knowledge. We further indicate how successful experimental designs can help us to obtain correct simulations, and thus to bring us to scientifically-empirically based counterfactual knowledge. (shrink)

The purpose of this study was to examine the effect of group art therapy using traditional Chinese materials on improving the self-efficacy and social function of individuals diagnosed with schizophrenia. In China, little research has been conducted on patients to measure the effectiveness of group art therapy, especially using traditional Chinese materials. To address this research gap, 104 individuals diagnosed with schizophrenia were tested in a group art therapy program that included 30 treatment sessions and used a wide variety of (...) materials, including traditional Chinese materials, such as Chinese calligraphy, traditional Chinese painting, Chinese embroidery, and Chinese beads. The effect of art therapy was analyzed using the General Self-Efficacy Scale and Scale of Social Skills for Psychiatric Inpatients. This study demonstrates that group art therapy using traditional Chinese materials can improve self-efficacy and social function, reducing social and life function problems, and promote the recovery of individuals diagnosed with schizophrenia.

To evaluate the performance of rural land circulation mode through the analytic network hierarchy process, based on the results of the performance evaluation with analytic network process, we implemented efficiency analysis on five types of rural land circulation mode by two improved efficiency analytic procedures. Finally, we implemented sensitivity analysis for each criterion layer of the evaluation index system with the performance evaluation data, interpreted five types of rural land circulation mode from three perspectives including benefits, costs, and risks with (...) sensitivity analysis results, and drew related conclusions including higher revenue which will lead to smaller difficulty of the rural land circulation. Cost variables were negative variables of the selected rural land circulation mode, and higher risk would lead to the greater difficulty of rural land circulation and related conclusions. (shrink)

School belonging is of great significance to students' physical and mental health development, especially academic improvement. However, the mechanism of the influence of school belonging on student academic achievement should be further explored, especially reading performance. Based on ecological systems theory and self-determination theory, the present research constructs a multilevel design to examine a moderated mediation model in which school belonging as a level-1 predictor, mastery goal orientation as a level-1 mediator and school disciplinary climate as a level-2 moderator jointly (...) impact reading literacy. Results of the study were based on the questionnaires from 11,364 15-year-olds nested in 332 schools in mainland China that participated in PISA 2018. The cross-sectional analysis indicated that: school belonging had a direct and positive effect on student reading literacy; the relationship between school belonging and reading literacy was prominently mediated by mastery goal orientation; both school disciplinary climate level and strength could negatively moderate the latter half path of “school belonging → mastery goal orientation → reading literacy.” Implications, limitations, and future research directions are discussed.

Given the current popularization of computer programming and the trends of informatization and digitization, colleges have actively responded by making programming lessons compulsory for students of all disciplines. However, students from different ethnic groups often have different learning responses to such lessons due to their respective cultural backgrounds, the environment in which they grew up, and their consideration for future employment. In this study, an AI-assisted programming module was developed and used to compare the differences between multi-ethnic college students in (...) terms of their theoretical and actual learning expectancy, motivation, and effectiveness. The module conducted analysis through the deep learning network and examined the relevant processes that the students underwent during programming lessons, as well as the types of errors they had committed. Their learning motivation for and actual learning performance in programming were then examined based on the cognitive learning theory. The results of the experiment, which involved 96 multi-ethnic college students, indicated that the two groups had dissimilar theoretical performance in terms of their expectancy and motivation for learning programming. The indigenous students’ main concern was whether programming would affect their families or tribes, and this concern affected and was reflected in their learning outcomes. In contrast, the learning motivation and goals of Han Chinese students were driven by the cognition of the value of programming to themselves. The research findings can contribute toward the cognition and understanding of multi-ethnic students when learning computer programming and development of the appropriate teaching methods, and serve as a reference for subsequent research on integrating multiculturalism into computer programming lessons.

Carbon emission has negative externalities, which will cause severe natural and social problems. In recent years, more and more attention has been paid to carbon emission reduction issue both in academic and application fields. This paper aims to explore the impact of punitive carbon tax and incentive carbon emission reduction subsidy on economy and environment through the dynamic stochastic general equilibrium framework. The results show that both carbon tax and carbon emission reduction subsidy policies can help to reduce carbon emissions (...) and to improve environment quality. In addition, carbon emission reduction subsidy has a positive impact on economy, while carbon tax has the opposite impact. It follows that the incentive carbon emission reduction policy is more conducive to the coordinated development of economy and environment. This research can be a guideline for the government to formulate carbon emission abatement policies from the perspective of coordinated development. (shrink)

Current research considers business model innovation as a series of responses to technological change and market environment change. However, in practice, it is often business model innovation that leads to market innovation and subversion and then promotes a new round of iterative product renewal. This is because business model innovation is a value creation activity based on market demand, rather than a technology-oriented innovation behavior. Moreover, since the degree of demand manifestation varies, the degree of its influence on value creation (...) and thus the driving mechanism for business model innovation vary significantly, and the duality of market-oriented theory is introduced to explore how firms go about achieving business model innovation based on different demand characteristics and how the results of firms’ integration of market information work. Through regression analysis of 230 sample enterprises, the results show that both responsiveness and proactive market orientation have a significant positive impact on business model innovation. In contrast, market information integration has a positive regulatory effect on the two groups of relationships. (shrink)

Enhancing urban development vitality and optimizing the allocation of regional industrial factors require a comprehensive analysis of listed companies, such as the overall distribution network, agglomeration evolution trend, industrialization layout, and driving mechanism. Using 1,624 A-share listed companies in China's Yangtze River Economic Belt as research area, this study integrated trend surface analysis, exploratory spatial data analysis, standard deviation ellipse, and spatial regression model methods. The main results are as follows: The overall quantity scale of the listed companies in the (...) Yangtze River Economic Belt has achieved significant growth, but the spatial difference of location selection persists. The spatial configuration formed a hierarchical urban distribution pattern with the Yangtze River Delta region as the agglomeration core and the provincial capitals as the fulcrum. Listed companies accelerate the expansion of the Yangtze River Delta region. Chengdu, Wuhan, Changsha, and other central-western provincial capitals gradually increased the region’s attractiveness. High-high and low-low agglomerations remain the main forms of agglomeration. There are significant differences in the location selection of listed companies with varying specialization levels, forming a relatively different alienated high-value distribution structure among various industry types. The levels of knowledge spillover, city scale, and policy support level are major factors affecting the location selection process of listed companies in the Yangtze River Economic Belt. For low-level city network with few listed companies, city scale and knowledge spillover levels are significant determinants for the development of headquarters’ economy. For high-level city network, along with the level of knowledge spillovers and policy support, globalization level has an important contribution to the shaping of the location advantages of attracting the layout of listed companies.

Using a data set of 30 authentic institutional emails written by Chinese college students to their native English teacher, this article investigates the frequency and combinations of apology strategies used by English as a Foreign Language learners in natural contexts. Drawing on the coding framework adapted from previous studies, this article carries out a fine-grained analysis of apology behaviors of Chinese EFL learners when they offended their teacher for various reasons. Results revealed that the most frequently used strategy was illustrative (...) force indicating devices, and “IFIDs + taking on responsibility” ranked the most frequent combination. Among IFID sub-strategies, an expression of regret had the highest frequency. In addition, a new strategy—request for a chance to repair—was identified, which was used by Chinese learners to show their respectful and pious attitude when a more serious offense was made to their teacher. Findings from the study indicate that Chinese EFL learners tend to use culture-specific apology strategies in academic contexts. This study has pedagogical implications for EFL pragmatics instruction in Chinese contexts and also second language pragmatics instruction tailored for native Chinese learners in English-speaking countries.

The existing differential item functioning detection approaches relying on item difficulty or item discrimination are limited for understanding the associates of DIF items, and consequently, DIF items were conventionally either deleted or ignored. Given the importance of minimizing DIF items in test construction, teachers or testing practitioners need more information regarding possible associates of DIF items. Using an example of a teacher-made mathematics achievement test, this study aimed to examine how the Poly-BW indices contributed to the properties of gender-related DIF (...) items. Data from a 34-item mathematics achievement test that involved 1,439 seventh-grade students from Taiwan showed that the differences of the defenselessness and power indices between men and women served as salient predictors of the DIF measures estimated by the Poly Simultaneous Item Bias Test procedure and with satisfactory accuracy of hit rates. Items with relatively large defenselessness for men were likely to present male-favoring DIFs, whereas items with relatively large power for men were likely to present female-favoring DIFs. The Poly-BW indices yielded directions for modifying items for teachers in practice. (shrink)
