This study conducts a bibliometric analysis of news discourse analysis using CiteSpace to sketch its scientific landscape based on journal articles in English in the Scopus database from 1988 through 2020. The statistical analysis provides evidence for the interdisciplinarity of this area, and shows an upward trend in general over these years as well as an accelerating growth rate in the past decade. Findings also indicate that the problem-oriented CDA has gained the most popularity in this area since its emergence, (...) and the appraisal framework, multimodality analysis, and discursive news values have become three hotspots of news discourse analysis. In addition, the authors in the West have contributed most in this area, but those from Chinese Mainland, Malaysia, South Africa, and Indonesia have gradually been an emerging powerhouse, which has added diversity in topics and will enhance equality and promote dialogue between different communities, ethnics, and races across the globe.

We prove that for any computably enumerable degree c, if it is cappable in the computably enumerable degrees, then there is a d.c.e. degree d such that c d = 0′ and c ∩ d = 0. Consequently, a computably enumerable degree is cappable if and only if it can be complemented by a nonzero d.c.e. degree. This gives a new characterization of the cappable degrees.

The principal–principal perspective suggests that controlling shareholders have excessive influence on corporate philanthropy and may direct corporate funds to charitable causes to support their personal interests. Analysis of a sample of Chinese private firms listed on the Shenzhen or Shanghai stock exchange between 2004 and 2011 shows that there is a significant and negative relationship between corporate giving and the share held by the largest shareholders, suggesting that controlling shareholders are opportunistic in directing corporate charitable contributions; there is a significant (...) and positive relationship between corporate giving and the political connections of the largest shareholders and their agents, suggesting compatibility between corporate contributions and the personal interests of the controlling shareholders; there is a stronger negative relationship between corporate giving and the share of the company held by the largest shareholders in politically connected firms, suggesting that political connections contribute to increased opportunistic corporate giving. Overall, our study provides important evidence for the “one dominant controlling shareholder” phenomenon by testing and extending the principal–principal framework and showing that the largest shareholders of Chinese firms appear to donate to charitable causes that ultimately serve their personal interests at the expense of minority shareholders.

Interval time-varying delay is common in control process, e.g., automatic robot control system, and its stability analysis is of great significance to ensure the reliable control of industrial processes. In order to improve the conservation of the existing robust stability analysis method, this paper considers a class of linear systems with norm-bounded uncertainty and interval time-varying delay as the research object. Less conservative robust stability criterion is put forward based on augmented Lyapunov-Krasovskii functional method and reciprocally convex combination. Firstly, the (...) delay interval is partitioned into multiple equidistant subintervals, and a new Lyapunov-Krasovskii functional comprising quadruple-integral term is introduced for each subinterval. Secondly, a novel delay-dependent stability criterion in terms of linear matrix inequalities is given by less conservative Wirtinger-based integral inequality approach. Three numerical comparative examples are given to verify the superiority of the proposed approach in reducing the conservation of conclusion. For the first example about closed-loop control systems with interval time-varying delays, the proposed robust stability criterion could get MADB about 0.3 more than the best results in the previous literature; and, for two other uncertain systems with interval time-varying delays, the MADB results obtained by the proposed method are better than those in the previous literature by about 0.045 and 0.054, respectively. All the example results obtained in this paper clearly show that our approach is better than other existing methods. (shrink)

This study provides an attributional perspective to the ethical leadership literature by examining the role of attributed altruistic motives and perceptions of organizational politics in a moderated mediation model. Path analytic tests from two field studies were used for analyses. The results support our hypotheses that attributed altruistic motives would mediate the relationship between perceived ethical leadership and affective organizational commitment. Moreover, the relationship between perceived ethical leadership and attributed altruistic motives was stronger when perceptions of organizational politics were high (...) but weaker when these perceptions were low. The study concludes with a discussion of future research implications as well as managerial implications. (shrink)

Lachlan observed that any nonzero d.c.e. degree bounds a nonzero c.e. degree. In this paper, we study the c.e. predecessors of d.c.e. degrees, and prove that given a nonzero d.c.e. degree , there is a c.e. degree below and a high d.c.e. degree such that bounds all the c.e. degrees below . This result gives a unified approach to some seemingly unrelated results. In particular, it has the following two known theorems as corollaries: there is a low c.e. degree isolating (...) a high d.c.e. degree [S. Ishmukhametov, G. Wu, Isolation and the high/low hierarchy, Arch. Math. Logic 41 259–266]; there is a high d.c.e. degree bounding no minimal pairs [C.T. Chong, A. Li, Y. Yang, The existence of high nonbounding degrees in the difference hierarchy, Ann. Pure Appl. Logic 138 31–51]. (shrink)

The current study mainly explored the influence of fluid intelligence and emotional intelligence on affective decision-making from a developmental perspective, specifically, during the transition from childhood into early adolescence. Meanwhile, their age-related differences in affective decision-making were explored. A total of 198 participants aged 8–12 completed the Iowa Gambling Task, the Cattell’s Culture Fair Intelligence Test and the Trait Emotional Intelligence Questionnaire-Child Form. Based on the net scores of IGT, the development of affective decision-making ability did not increase monotonically with (...) age, and there was a developmental trend of an impaired IGT performance in early adolescence, especially in the early learning phase of the IGT. More importantly, IQ and EI played different roles for children and early adolescents: IQ and EI jointly predicted the IGT performance for 8–10 years old children, whereas only EI contributed to the IGT performance of 11–12 years old early adolescents. The present study extends the evidence how cognitive processing and emotional processing interact in affective decision-making from the developmental perspective. Furthermore, it provides insights of future research and intervention with early adolescents’ poor affective decision-making. (shrink)

This study aims to examine the neural correlates of cognitive shifting during the Dimensional Change Card Sort Task task with functional near-infrared spectroscopy. Altogether 49 children completed the DCCS tasks, and 25 children passing all items were classified into the Switch group. Twenty children committing more than one perseverative errors were grouped into the Perseverate group. The Switch group had Brodmann Area 9 and 10 activated in the pre-switch period and BA 6, 9, 10, 40, and 44 in the post-switch (...) period. In contrast, the Perseverate group had BA 9 and 10 activated in the pre-switch period and BA 8, 9, 10 in the post-switch period. The general linear model results afford strong support to the “V-shape curve” hypothesis by identifying a significant decrease–increase cycle in BA 9 and 44, the neural correlations of cognitive shifting.

In this study, for COVID-19, we divide people into four categories: susceptible S t, closely contacted C t, infective I t, and removed R t according to the current epidemic situation and then investigate two models: the SCIR models with immigration and without immigration. For the former, Model 1, we obtain the condition for global stability of its disease-free equilibrium. For the latter, Model 2, we establish the local asymptotic stability of its endemic equilibrium by constructing Lyapunov function. Afterwards, by (...) the bifurcation theory, we qualitatively analyze the properties of its Hopf bifurcations of the latter. Finally, numerical simulations are given to illustrate the obtained results of two models. The results imply the importance of finding closely contacted and overseas imports on epidemic control. It indicates that not only the incubation delay τ is crucial for the containment of the COVID-19 but also the scientific and rigorous containment measures are the key factors of the success of the containment.

Under the dual background of underemployment and health inequality, this study empirically analyzes the impact of education level on underemployed workers’ health based on data from the 2016 China Labor-force Dynamics Survey. The results show that underemployment is significantly related to the decline of self-rated health, increased depressive tendencies, and the prevalence of illness over a certain period. The results indicate that underemployment can significantly reduce the health level of workers in both low and high education level groups. However, underemployment (...) appears to have no significant impact on workers’ health in the middle education level group. This result holds even if the measurement method of the indicators is adjusted and endogeneity is considered; this indicates that the research conclusions are robust. Moreover, this kind of health inequality mainly comes from the economic and leisure effects of underemployment for workers with different educational levels. Although underemployment significantly reduces the economic level of workers in each education level group, it brings a positive leisure effect to workers with a middle education level and a negative leisure effect to workers with a low education level. This study provides empirical support for increasing labor protection mechanisms for underemployed people and reducing the health inequality caused by differences in education level. (shrink)

: Filial piety is a core value in ancient Chinese culture, and it still exerts significant influence on the attitudes, behavior and daily life of Chinese people today. At present, China is facing an increasingly aging population and the concern how to properly care for the elderly. Through the vertical review of filial piety in China’s history, two constant elements, namely support and respect, stands out among China’s traditions. There is an argument that addressing the contemporary elderly care problem requires (...) the adequate support from two perspectives, material support from families and societies for the aged and spiritual caring for them. It is further argued that any approaches aimed at addressing contemporary elderly care issue should take into consideration the actual social and culture conditions in China, including the cultural traditions of filial piety. Resumo: A piedade filial era um valor central na cultura chinesa antiga, e ainda exerce influência significativa nas atitudes, comportamento e vida cotidiana do povo chinês. Atualmente, a China está enfrentando uma população cada vez mais envelhecida e as preocupações associadas a como cuidar adequadamente dos idosos do país. Através da revisão vertical da piedade filial, ao longo da história da China, para este trabalho, dois elementos constantes emergiram nas tradições, a saber, apoio e respeito. Argumenta-se que a abordagem do problema contemporâneo do cuidado ao idoso exigirá a incorporação adequada de ambas as dimensões, ou seja, fornecer não apenas apoio material ao idoso, na família e na sociedade, mas também prover seu cuidado espiritual. Argumenta-se ainda que quaisquer abordagens destinadas a tratar da questão devem ser baseadas nas condições sociais e culturais reais, na China, incluindo e passando além das tradições culturais de piedade filial.

The problem of rationalizing denominators for two types of fractions is discussed in the paper. By using the theory and algorithms of Gröbner bases, we first introduce a method to rationalize the denominators of fractions with square root and cube root, and then, for the denominators with higher radical of the general form, the problem of rationalizing denominators is converted into the related problem of finding the minimal polynomials. Some interesting results and an executable algorithm for rationalizing the denominator of (...) these type fractions are presented. Furthermore, an example is also established to illustrate the effectiveness of the algorithm. (shrink)

Lung nodules are an early symptom of lung cancer. The earlier they are found, the more beneficial it is for treatment. However, in practice, Chinese doctors are likely to cause misdiagnosis. Therefore, deep learning is introduced, an improved target detection network is used, and public datasets are used to diagnose and identify lung nodules. This paper selects the Mask-RCNN network and uses the dense block structure of Densenet and the channel shuffle convolution method to improve the Mask-RCNN network. The experimental (...) results prove that proposed algorithm is extremely effective. (shrink)

Based on the perspective of the regional innovation system, this study constructs an analytical framework for the influence of government R&D funding on regional innovation quality and uses 283 Chinese cities as research samples to empirically test the influence of government R&D funding methods such as subsidies and tax preferences on regional innovation quality by the spatial Durbin model. According to the study, China’s regional innovation quality has a positive spatial correlation. Subsidies can improve regional innovation quality, which is mainly (...) realized by increasing the input of innovation resources from local direct innovation subjects, attracting the inflow of innovation resources from neighboring areas, and increasing the innovation support from local indirect innovation subjects. Besides, spatial competition for subsidies makes it beneficial to improve the regional innovation quality in neighboring regions, while the promotion effect of tax preferences is not significant. When considering the heterogeneity of the city location and administrative hierarchy, it shows that the government R&D funding cannot improve the innovation quality of the Eastern cities and higher-administrative-hierarchy cities, while it can improve that of the Middle and Western cities and general-administrative-hierarchy cities. Furthermore, government R&D funding widens the gap of regional innovation quality, which may be related to the existing “insufficient intervention” and “excessive intervention” of government R&D funding. This study provides insights into the implementation of R&D funding by the government to promote the development of regional innovation quality. (shrink)

COVID-19 has affected every aspect of our life, including economic, social, and academic. Exchange and mobility students face more difficulties overseas, and Chinese students are no exception. However, e-learning has been introduced by institutions in many countries. The present study examines the psychosocial factors affecting the academic performance of Chinese outbound exchange and mobility students during the COVID-19 pandemic. The study surveys about 186 Chinese outbound exchange and mobility students. The present study performs the quantitative data analysis using Partial Least (...) Square Structural Equation Modeling through the Smart PLS software version 3. By confirming the measurement model and structural model assessments, the study finds that personality, social support, and language fluency are psychosocial factors that significantly influence the exchange and mobility students’ academic performance. This study contributes by establishing relationships among psychosocial factors, language fluency and academic performance. Besides, practitioners can be benefitted by understanding students’ psychosocial factors and its relation to academic performance during COVID-19 pandemic. (shrink)

In order to deal with high-dimensional distributed data, this article develops a novel and communication-efficient approach for sparse and high-dimensional data with the penalized quantile regression. In each round, the proposed method only requires the master machine to deal with a sparse penalized quantile regression which could be realized fastly by proximal alternating direction method of multipliers algorithm and the other worker machines to compute the subgradient on local data. The advantage of the proximal ADMM algorithm is that it could (...) make every parameter of iteration to have closed formula even in high-dimensional case, which greatly improves the speed of calculation. As for the communication efficiency, the proposed method does not sacrifice any statistical accuracy and provably improves the estimation error obtained by centralized method, provided the penalty levels are chosen properly. Moreover, the asymptotic properties of the proposed estimation and the convergence of the algorithm are convincible. Especially, it presents extensive experiments on both the numerical simulations and the HIV drug resistance data analysis, which all confirm the significant efficiency of our proposed method in quantile regression for distributed data by comparative and empirical analysis.

Heterogeneous institutional investors' shareholding preferences have been driven to change by the deepening of ESG investment philosophy. Therefore, we examine the impact of corporate ESG performance on institutional investors' shareholding preferences and its mechanism of action. We conduct mixed OLS and mediation effect tests using data on ESG responsibility scores and institutional investors' shareholding ratios of A-share listed companies in China from 2010 to 2020 as samples. We find that corporate ESG performance can significantly and robustly increase institutional investors' shareholdings; (...) the mediation effect analysis shows that overall corporate ESG performance contributes to increases in corporate book and market values, thus encouraging institutional investors to increase their shareholdings. The heterogeneity analysis shows that independent institutional investors attach more importance to corporate ESG responsibility performance, and long-term institutional investors attach more importance to corporate environmental performance; moreover, institutional investors have more significant ESG shareholding preferences for Chinese SOEs. Our study can strengthen the encouragement of institutional investors to integrate ESG investment concepts from multiple perspectives, such as research and analysis, portfolio management, risk control, and due diligence management, to design and develop targeted ESG investment tools, give full play to the role of shareholders and guide the sound development of listed companies from the perspective of investment strategy objectives.

Factory workers make up a large proportion of China’s internal migrants and may be highly susceptible to job and adaptation stress, negative affective states, and Internet gaming disorder. This cross-sectional study investigated the relationships between job stress, psychological adaptation, negative affective states and IGD among 1,805 factory workers recruited by stratified multi-stage sampling between October and December 2019. Structural equation modeling was conducted to test the proposed mediation model. Among the participants, 67.3% were male and 71.7% were aged 35 years (...) old or below. The prevalence of probable depression, probable anxiety, and IGD was 39.3, 28.7, and 7.5%. Being male, younger age, and shorter duration of living in Shenzhen were associated with higher IGD scores. Job stress was significantly associated with IGD but not with negative affective states. Psychological adaptation was significantly associated with negative affective states. Negative affective states were positively associated with IGD. The indirect effect of psychological adaptation but not job stress on IGD through negative affective states was statistically significant. The observed psychological correlates and mechanisms are modifiable, and can inform the design of evidence-based prevention programs for depression, anxiety, and IGD in this population. (shrink)

Holistic thinking involves four subconstructs: causality, contradiction, attention to the whole, and change. This holistic perspective varies across Eastern–Western cultures and genders. We theorize that holistic thinking reduces three domain-specific risk-taking behavioral intentions (ethical, financial, and health/safety) directly and indirectly through enhanced risk-taking attitudes. Our formative theoretical model treats the four subconstructs of holistic thinking as yoked antecedents and frames it in a proximal context of causes and consequences. We simultaneously explore the direct and indirect paths and test our model (...) across cultures, genders, and the combination of the two. For the entire sample (N = 531), holistic thinking negatively relates to risk intentions via enhanced risk perceptions. Across cultures, the indirect paths prevail among Chinese people (n = 284), and both direct and indirect paths triumph for Americans (n = 247). Across genders, the indirect paths exist for females, whereas the negative direct path (risk-raking attitudes → behavioral intentions) succeeds for males. Across cultures and genders, holistic thinking negatively relates to American males’ ethical risks the most but Chinese males’ financial risks the least. Risk-taking perceptions are negatively related to Chinese males’ ethical risks the most, but Chinese people’s (males/females) financial risks the least. Causality and change are vital for all contexts, attention to the whole for all males and Chinese males, and contradiction for Americans and all females. Holistic thinking has limits and is less robust than risk-taking perceptions in reducing risky behavioral intentions. Our practical implications help people make ethical, healthy, and wealthy decisions. (shrink)

Attention has been theorized as a system comprising three networks that can be estimated reliably by the attention network test ; the three networks are defined as alerting, orienting, and conflict control. The present study aims to identify the attention networks that are crucial for elite shooting and archery athletes and to examine whether mindfulness training can improve elite athletes' attention networks. We compared the performances in ANT between 62 elite athletes from the Chinese national team of shooting and archery (...) and 49 athletes from a provincial team in China. The results indicate three well-functioned attention networks in both groups, but elite athletes in the national team responded faster overall than athletes in the provincial team. The 62 elite athletes in the national team then received mindfulness training with varied periods ranging from 5 to 8 weeks, after which the ANT was re-administered. After mindfulness training, the elite athletes improved in orienting and conflict control networks compared with their pre-training performances. These results suggest that elite shooting and archery athletes in the national team are more efficient in all three attention networks, which means that they are able to reach the alerting state faster, make better use of environmental information, and suppress interference from distractors more efficiently. Moreover, the orienting and conflict control networks of the elite shooting and archery athletes can be improved by mindfulness training. We conclude that mindfulness practice should be considered as a useful addition to daily training for shooting and archery athletes. (shrink)

We examine enforcement action in China’s emerging markets by focusing on the agents that impose this action and the role played by supervisory boards. Using newly available databases, we find that supervisory boards play an active role when Chinese listed companies face enforcement action. Listed firms with larger supervisory boards are more likely to have more severe sanctions imposed upon them by the China Security Regulatory Commission, and listed companies that face more severe enforcement actions have more supervisory board meetings. (...) Our findings are of interest, as supervisory boards in China are generally perceived to be dysfunctional. This study contributes to the existing literature in three ways. First, we shed light on the effects of supervisory boards whose role in a fraud setting has not yet been examined. Second, the study has important policy implications for governance reform. Finally, our analyses provide the most up-to-date picture of fraud and governance issues in China’s ever-growing markets. (shrink)

This study aimed to analyze the relations between class competition and primary school students’ academic achievement, considering the possible mediating roles of learning anxiety and learning engagement. Participants were 1,479 primary school students from four primary schools in Zhejiang, China. We analyzed participants’ scores for class competition, learning anxiety, and learning engagement and their last two final exam scores. Class competition did not directly predict academic achievement, but indirectly affected academic achievement through learning anxiety and learning engagement. There were three (...) effect paths: class competition negatively predicted academic achievement by increasing learning anxiety; class competition positively predicted academic achievement by promoting learning engagement; and class competition affected academic achievement through multiple mediating effects of learning anxiety and learning engagement. This study highlights the important roles of learning anxiety and learning engagement in class competition and academic achievement, which have theoretical and practical significance. (shrink)

We examine the dynamics between enforcement actions and the responses from both the board of directors and supervisory boards amid China's governance reform. Rather than examining determinants of fraudulent activities, we investigate, after enforcement actions are imposed, whether the board of directors and supervisory boards react differently, and whether their different reactions play a role in preventing future occurrences of frauds. We find that both boards react to enforcement actions, but only the responses from the board of directors help us (...) curb future enforcements under certain circumstances. The supervisory board fails to play any role in preventing future enforcements, even though it is one of the two monitoring mechanisms in the listed companies. Policy implications are discussed.
