The fiscal imbalance between the central and local governments under fiscal centralization may motivate local governments to pass tax burdens on firms. The causal identification of the tax system reform and the sustainable export innovation behavior of firms are of great significance. This study uses the income tax sharing policy of China to examine the impact of fiscal centralization on the sustainable export innovation behavior of firms. We find that this tax reform has significantly inhibited the increase of the export (...) value-added rate of firms, and has an increasing trend with the share ratio between the Central Government and the local government. Moreover, this effect mainly comes from the crowding-out effect of imported intermediate goods on domestic intermediate goods. The tests show that the above conclusions are consistent with the general logic of local governments. When they face greater downward fiscal pressure, they will further pass the tax burden on local firms and force the firms to promote their export performance to expand the tax base. This short-sighted behavior of replacing “quality improvement” with “quantity increase” is an important factor that affects the sustainable export innovation behavior of firms and the climb in the global value chain.

For synchronization of a class of chaotic systems in the presence of nonvanishing uncertainties, a novel time-varying gain observer-based sliding mode control is proposed. First, a novel time-varying gain disturbance observer is developed to estimate the uncertainties. Then, by using the output of TVGDO to modify sliding mode control, a new TVGDO-based SMC scheme is developed. Although the observation and control precision of conventional fixed gain disturbance observer-based control for chaotic systems can be guaranteed by a high observer gain, the (...) undesirable spike problem may be caused by the high gain if the initial values of estimate and true states are not equal. The most attractive feature of this work is that the newly proposed TVGDO can eliminate the spike problem by developing a time-varying gain scheme. Finally, the effectiveness of the proposed method is demonstrated by the numerical simulation. (shrink)

This paper proposes a novel robust fixed-time control for the robot manipulator system with uncertainties. Based on the uniform robust exact differentiator algorithm, a robust control term is constructed. Then, a robust fixed-time inverse dynamics control is proposed. For the proposed control method, the fixed-time stability of a closed-loop system with uncertainties is strictly proved. The newly proposed method exhibits the following two attractive features. First, the proposed control scheme extends the existing fixed-time IDC for the robot manipulator system to (...) the robust control scheme. Second, the proposed method is strictly nonsingular rather than the commonly used approximate approach. Simulation result demonstrates the effectiveness of the proposed control scheme. (shrink)

To realize the coordinated and sustainable development of hydropower projects and regional society, comprehensively evaluating hydropower projects’ influence is critical. Usually, hydropower project development has an impact on environmental geology and social and regional cultural development. Based on comprehensive consideration of complicated geological conditions, fragile ecological environment, resettlement of reservoir area, and other factors of future hydropower development in each country, we have constructed a comprehensive evaluation index system of hydropower projects, including 4 first-level indicators of social economy, environment, safety, (...) and fairness, which contain 26 second-level indicators. To solve the problem that existing models cannot evaluate dynamic nonlinear optimization, a projection pursuit model is constructed by using rough set reduction theory to simplify the index. Then, an accelerated genetic algorithm based on real number coding is used to solve the model and empirical study is carried out with the Y hydropower station as a sample. The evaluation results show that the evaluation index system and assessment model constructed in our paper effectively reduce the subjectivity of index weight. Applying our model to the social impact assessment of related international hydropower projects can not only comprehensively analyze the social impact of hydropower projects but also identify important social influencing factors and effectively analyze the social impact level of each dimension. Furthermore, SIA assessment can be conducive to project decision-making, avoiding social risks and social stability. (shrink)

Viewed from some postcolonial/postmodern perspectives by employing mostly the micropolitics of Homi Bhabha’s and Gilles Deleuze (and other theorists who hold similar conceptions), whose major common interest lies in dismantling the myth of establishing an imagined community by retrieving a shared national history/culture and assuming ethnic purity, this paper seeks to explore the paradoxical aspects of Taiwan’s quest in her decolonizing progress for a “collective” national/cultural identity. Besides, this paper compares mostly Taiwan’s decolonization process with South Korea’s because of their (...) similarity in territorial division due to some civil wars and the intervention of external powers (e.g., the former Soviet Union and U.S.A.). By so doing, this paper aims to propose some solution to Taiwanese’s dilemma in constructing a “collective” national /cultural identity. (shrink)

We recast parts of decision theory in terms of channel theory concentrating on qualitative issues. Channel theory allows one to move between model theoretic and language theoretic notions as is necessary for an adequate covering. Doing so clarifies decision theory and presents the opportunity to investigate alternative formulations. As an example, we take some of Savage’s notions of decision theory and recast them within channel theory. In place of probabilities, we use a particular logic of preference. We introduce a logic (...) for describing actions separate from the logic of preference over actions. The structures introduced by channel theory that represent the decision problems can be seen to be an abstract framework. This frame-work is very accommodating to changing the nature of the decision problems to handle different aspects or theories about decision making. (shrink)

This study explored the correlation between mental toughness and physical activity, and the moderation role between PA intention and subsequent behavior among college students and wage earners. Five hundred ninety-one college students aged from 19 to 24 and 285 wage earners aged from 27 to 58 recruited from seven colleges and five cities in China. A Theory of Planned Behavior questionnaire, MT Inventory, and the International PA Questionnaire was completed online. Results showed that attitudes, subjective norms, and perceived behavioral control (...) explained 46.5 and 38.3% variance in PA intention among college students and wage earners separately. Intention predicted PA behavior significantly among college students and wage earners. Structural equation modeling indicated that the TPB model and the moderation model have an adequate to good fit except the TPB model among wage earners. MT was positively correlated with PA among college students and wage earners and had a significant moderation role in intention-behavior gap among college students and partially affected the transfer of PA intention to behavior among college students. Individuals with high MT had high levels of PA regardless of intention, while PA of those with low MT was low and unstable. Future research should further explore the correlation between intention and PA and the moderation role of MT in different populations using a longitudinal study in order to better understand the correlation between intention and PA, and the transition from intention to PA and better guidance PA intervention to promote PA.

The pressure control for a liquid nature gas ship is vital for the cargo handling system which is a nonlinear, unstable, and controllable complex system accompanied by the dynamics of time delay. To improve the control effect, this article proposed a robust controller based on closed-loop gain shaping algorithm by mirror-mapping approach. In addition, the complete mechanism models for the system are established to predict the changes of temperature, pressure, and liquid inventory in the cargo tank. The heat exchanges and (...) evaporation of liquid are also considered. By collecting the data from the LNG ship “Dapeng,” the system models are validated. At the same time, the comparative experiment is introduced to verify the reliability and effectiveness. The scheme has been compared with the 2-DOF structure control law of modified Smith predictor. The comparative experimental results show that the scheme proposed in this note has a strong disturbance rejection ability and steady-state performance. The controller designed in this note has advantages of simplified construction method, satisfactory control effect and robustness. (shrink)

We show that there exists a properly Σ2 minimal degree b, and moreover that b can be chosen to join with 0′ to 0″ – so that b is a 0″ complement for every degree a such that 0′ ≤ a < 0″.

An incline S is a commutative semiring where r+1=1 for any r \in S . We note that the ideal lattice of an S-semimodule is naturally an S-semimodule and so is its congruence lattice when S is transitive. We prove that the categories of complete S-semimodules, together with dual functor, internal hom and tensor product, is a ⋆-autonomous category. We define the locally and globally maximal congruences which are related to Birkhoff subdirect product decomposition. We show that the categories of (...) S-semimodules, algebraic S-semimodules and topological S-semimodules are equivalent. Finally, we get a sheaf representation of any S-semimodule. (shrink)

Evidence suggests that participation in plaza dancing may affect mental health. This study for the first time quantified the relationships between plaza dancing and psychological well-being and ill-being. We systematically searched PubMed, Web of Science, CNKI, Wanfang, and VIP to identify relevant studies published from the databases since their inception to July 25, 2021. The standardized mean differences of pre-to-post intervention data were calculated in the meta-analysis. Subgroup and meta-regression analyses were performed to test the potential moderating effects of age, (...) outcome classification, measurement instruments, district, publication year, total sample size, and the duration, frequency, and length of the square dance intervention. A total of 25 original articles met all the eligibility criteria and were included in the review, and 17 studies were included in the meta-analysis. The meta-analysis revealed that plaza dancing improved psychological well-being and reduced psychological ill-being. The study participants’ age and district did not seem to affect the effectiveness of the plaza dancing intervention. The duration and frequency of plaza dancing affected the association between square dance and psychological well-being and psychological ill-being. Plaza dancing has a significant positive effect on psychological well-being and psychological ill-being, and the effects are moderated by intervention modality. Generalizing plaza dancing interventions to promote psychological well-being and prevent or treat psychological ill-being is needed.Systematic Review Registration[www.crd.york.ac.uk/prospero], identifier [CRD42021272016].

At the crossroads of poetry and philosophy: Francis Ponge and Maurice Merleau-Ponty The aim of the present article is to clarify the place of the sensitive dictionary in the work of Francis Ponge and to show how it denotes human's relationship to nature. To achieve that, we will use the body question as a measure of the human–nature relationship and apply the phenomenological method that Ponge took over from Merleau-Ponty. It should be noted that Merleau-Ponty rarely makes reference to Ponge's (...) poems, except for a few incisions in his Causeries. As for Ponge, he uses explicitly only the notion of phenomenological reduction to explain his project of sensitive dictionary. However, we will argue that there are many similarities of thought between the philosopher and the poet, which are still unexplored. (shrink)

Background:Ethical issues pose challenges for nurses who are increasingly caring for patients in complicated situations. Ethical sensitivity is a prerequisite for nurses to make decisions in the best interest of their patients in daily practice. Currently, there is no tool for assessing ethical sensitivity in Chinese language, and no empirical studies of ethical sensitivity among Chinese nurses.Research objectives:The study was conducted to translate the Moral Sensitivity Questionnaire–Revised Version (MSQ-R) into Chinese and establish the psychometric properties of the Moral Sensitivity Questionnaire–Revised (...) Version into Chinese (MSQ-R-CV).Research design:This research was a methodological and descriptive study.Participants and research context:MSQ-R was translated into Chinese using Brislin’s model, and the Translation Validity Index was evaluated. MSQ-R-CV was then distributed along with a demographic questionnaire to 360 nurses working at tertiary and municipal hospitals in Changsha, China.Ethical considerations:This study was approved by the Institutional Review Boards of Yale University and Central South University.Findings:MSQ-R-CV achieved Cronbach’s alpha 0.82, Spearman-Brown coefficient 0.75, significant item discrimination (p < 0.001), and item-total correlation values ranging from 0.524 to 0.717. A two-factor structure was illustrated by exploratory factor analysis, and further confirmed by confirmatory factor analysis. Chinese nurses had a mean total score of 40.22 ± 7.08 on the MSQ-R-CV, and sub-scores of 23.85 ± 4.4 for moral responsibility and strength and 16.37 ± 3.75 for sense of moral burden.Discussion:The findings of this study were compared with studies from other countries to examine the structure and meaningful implications of ethical sensitivity in Chinese nurses.Conclusion:The two-factor MSQ-R-CV (moral responsibility and strength, and sense of moral burden) is a linguistically and culturally appropriate instrument for assessing ethical sensitivity among Chinese nurses.

Classic genetics studies found that genomic imbalance caused by changing the dosage of part of the genome (aneuploidy) has more detrimental effects than altering the dosage of the whole genome (ploidy). Previous analysis revealed global modulation of gene expression triggered by aneuploidy across various species, including maize (Zea mays), Arabidopsis, yeast, mammals, etc. Plant microRNAs (miRNAs) are a class of 20‐ to 24‐nt endogenous small noncoding RNAs that carry out post‐transcriptional gene expression regulation. That miRNAs and their putative targets are (...) preferentially retained as duplicates after whole‐genome duplication, as are many transcription factors and signaling components, indicates miRNAs are likely to be dosage‐sensitive and potentially involved in genomic balance networks. This review addresses the following questions regarding the role of miRNAs in genomic imbalance. (1) How do aneuploidy and polyploidy impact the expression of miRNAs? (2) Do miRNAs play a regulatory role in modulating the expression of their targets under genomic imbalance? (shrink)

Based on a pre-order on a set, we axiomatize the Egli-Milner order on the power set and show how it is related to the Lewis order. Moreover, we consider a strict version of the Egli-Milner order and show how it can be related to the semantics of conditionals based on a priority structure.

In economic researches, much effort was devoted to the problem of how to increase the economics of countries. However, the development of a country may fluctuate a lot due to international and domestic problems. Thus, we should also evaluate the robustness of countries against unexpected economic recessions. In this paper, we use perturbation to quantify the robustness of countries using two renowned algorithms: method of reflections and fitness-complexity method. The robustness characterizes the stability of countries’ competitiveness against economic recessions. The (...) experiments in the international trade networks show that FCM could characterize the robustness better than MR. High fitness countries of FCM have strong robustness against economic crises, which enlarges the application fields of FCM. Additionally, we simulate the trade conflict between USA and China. The simulation results show that China suffers much in the trade conflict, while USA loses very little and has strong robustness in this conflict. (shrink)

A growing body of research has started to examine how individuals from different countries may differ in their use of ethically questionable tactics during business negotiations. Whereas prior research focused on the main effect of the national culture or nationality of the negotiator, we add a new factor, which is the nationality of the counterpart. Looking at both these variables allows us to examine whether and how people may change their likelihood of using ethically questionable tactics in inter-cultural negotiations as (...) opposed to intra-cultural ones. Results of an experiment show that overall, American participants were less likely than Chinese participants to use ethically questionable tactics in negotiations. However, American participants were more likely to use ethically questionable tactics, particularly those related to false promises and inappropriate information gathering, in inter-cultural negotiations with Chinese counterparts, than in intra-cultural negotiations with American counterparts. By contrast, Chinese participants were less likely to use ethically questionable tactics, particularly those related to false promises and attacking opponent’s network, in inter-cultural negotiations with American counterparts, than in intra-cultural negotiations with Chinese counterparts. Implications and future directions are discussed. (shrink)

For achieving the sustainable development goals, green development has been raised to a high position for cities in China. The economic development in Northwest China is slow, the ecological environment is fragile, and the mineral resources are rich. Only through green development can we realize the comprehensive income of regional production development, rich life, and good ecology. This paper measures the green development efficiency of 30 prefecture-level cities in Northwest China by using DEA-SBM model of unexpected output, explores the differences (...) and causes of green development efficiency from the perspective of time and space through convergence coefficient, coordination matrix, GIS, and other methods, and empirically tests the impact of industrial structure, technological progress, and other driving factors on green development efficiency by using panel Tobit model. The results show that, on the whole, the efficiency of green development in Northwest China is low, path dependence is serious and unbalanced, the coordinated development effect of different regions is weak, and the spillover effect of core urban agglomerations has not been effectively exerted; from the perspective of driving factors, economic development, population density, traffic situation, and education investment can significantly improve the efficiency of urban green development, and the second is that the proportion of industries significantly hinders the improvement of green development efficiency, while the impact of scientific and technological innovation is not significant. Based on the empirical results, this paper believes that the harmonious development of natural environment and economic society can be realized only by improving the coordinated development effect among cities, implementing the optimization and upgrading of industrial structure, introducing excellent talents, and promoting the technological upgrading.

To achieve environmental sustainability, the role of human capital and financial inclusion has been debated in limited empirical studies. Employing a reliable ARDL model approach, this study examines the dynamic link between human capital and ICT, financial inclusion, and CO2 emissions using the China economy dataset over the period 1998–2020. The vivacious side of human capital shows that literacy rate and average year of schooling curb CO2 emissions in long run. The results of human capital are also based on facts (...) in magnitude as well as in direction. Also, empirics unfold that digital financial inclusion significantly increases CO2 emissions. Based on these novel findings, a wide set of economic policies are repaired for environmental quality. Environmental education should be considered at early levels of education. The authorities and policymakers should fix energy-related issues through education. The China government should stimulate the educational sector to conduct a clean and green revolution that acts as a mechanism for a green and clean economy. This study's finding is more effective than the previous unlike empirical studies for policy-making because of the advanced econometric method. (shrink)

PurposeAsian Americans comprise 21% of matriculating medical students in the United States but little is known about their mental health. With the growing focus on addressing the mental health of medical students, this systematic, nationwide survey assesses the relationship between anxiety and depression symptoms and coping skills among Asian American medical students.Materials and methodsA survey tool comprised of Patient Health Questionnaire-9, General Anxiety Disorder-7, and questions related to coping were emailed to members of the Asian Pacific American Medical Students Association (...) enrolled in a United States medical school during the 2016–2017 academic year. We evaluated associations between anxiety and coping as well as depression and coping.ResultsA total of 511 Asian American medical students completed the survey. Anxiety symptoms were positively correlated with an increase in negative coping skills. Depressive symptoms were not correlated with an increase in negative coping skills.ConclusionProfessionals and medical schools that aim to improve the mental health of medical students should be aware of the needs of specific populations. Asian American students who experience anxiety were more likely to utilize avoidant or negative coping strategies. In addition, Asian American students who experience depressive symptoms were not more likely to utilize these negative coping strategies. Further research must be done to evaluate the factors that influence the use of negative coping strategies to better address anxiety within the Asian American medical student population. (shrink)
