With the rapid and unbalanced development of industry, a large amount of cultivated land is converted into industrial land with lower efficiency. The existing research is extensively concerned with industrial land use and industrial development in isolation, but little attention has been paid to the relationship between them. To help address this gap, the paper creates a new efficiency measure method for industrial land use combining Subvector Data Envelope Analysis with spatial analysis approach. The proposed model has been verified by (...) using the industrial land use data of 30 Chinese provinces from 2001 to 2013. The spatial autocorrelation relationship between industrial development and industrial land use efficiency is explored. Furthermore, this paper examines the effects of industrial development on industrial land use efficiency by spatial panel data model. The results indicate that the industrial land use efficiency and the industrial development level in the provinces of eastern region are higher than those of the western region. The spatial distribution of industrial land use efficiency shows remarkable positive spatial autocorrelation. However, the level of industrial development has obvious negative spatial autocorrelation since 2009. The improvement of industrial development has a significant positive impact on the industrial land use efficiency. (shrink)

Empathy and altruistic behavior are more crucial abilities for pre-service teachers to possess when compared with other study fields. The relationship between empathy and altruistic behavior in Chinese pre-service teachers and their underlying mechanisms, however, has received relatively little attention in the literature. Therefore, the goal of the current study was to examine the links between study fields, self-control, emotional empathy, and altruistic preferences among undergraduates and graduates in five Chinese universities with the Interpersonal Reactivity Index-C Questionnaire, the Self-Control Scale, (...) and the Chinese Self-Report Altruism Scale tests. The results showed a significant difference between pre-service and non-pre-service teachers in empathic concern and self-control. Furthermore, empathic concern and altruistic behavior tendency of pre-service teachers were significantly higher than those of non-pre-service teachers. Moreover, mediation analyses indicated that empathic concern partially mediated the relationship between study fields and altruistic tendency. Moderated mediation analysis further revealed that self-control buffered the relation between empathic concern and altruistic behavior tendency. These results demonstrate that altruistic tendency of pre-service teachers is influenced by empathic concern and self-control. (shrink)

Off-seat behaviour refers to students leaving their seats and walking out of a classroom without the teacher noticing. This behaviour occurs in special education for students with certain special needs, which would lead to serious safety problems. This study carried out an inattentional blindness test to explore whether the location of seats in classrooms would impact teachers’ detection rate regarding off-seat behaviours. The participants were 126 pre-service teachers who were invited to perform the primary task of counting students raising their (...) hands up whilst the disappearance of one of the students was introduced as an unexpected occurrence. The results show that peripheral seats were more detectable than the central ones for the teachers to notice the “missing student.” Meanwhile, the left and below oriented seats were more likely to be ignored compared to those that were right and upper oriented. These results suggest the existence of a location effect in the classroom that is associated with teachers’ attention regarding off-seat behaviour. This study has implications for classroom management in terms of arranging students’ seats appropriately to assist in increasing teachers’ identification of this hazard. (shrink)

With the development of industrialization and urbanization, cities have become the main carriers of economic activities. However, the long-term development of cities has also caused damage to resources and the environment. Hence, objective and scientific evaluation of urban low-carbon sustainable development capacity is very important. An index system of urban low-carbon sustainable development capability is constructed in this paper, and a TOPSIS-BP neural network model is established to evaluate the low-carbon sustainable development capability of Beijing, Shanghai, Shenzhen, and Guangzhou in (...) China. At the same time, the difference degree of low-carbon sustainable development level in these four cities is analyzed by standard deviation and coefficient of variation, and the influencing factors of urban low-carbon sustainable development ability are extracted by grey correlation analysis. The results show that the capability of low-carbon sustainable development in four cities is rising and the difference of low-carbon sustainable development capability is decreasing; the general view that the higher the general investment in low-carbon sustainable development, the higher the level of low-carbon sustainable development in cities has not been verified; with the change of time series, the factors affecting the capability of low-carbon sustainable development in the same city are different and the influence of the same factor on the capability of low-carbon sustainable development in different cities is different.

Purpose: This study used a moderated mediation model to test the mediating effect of general self-efficacy on the relationship between post-traumatic growth and creativity and the moderating effect of deliberate rumination in the second path of the indirect mediation path during the COVID-19 pandemic.Methods: A sample of 881 university students from Guangdong Province, China, was surveyed with the Posttraumatic Growth Inventory, the Runco Ideational Behavior Scale, the General Self-Efficacy Scale, and the Deliberate Rumination Inventory. SPSS and PROCESS were used for (...) correlation analyses, mediation analysis, and moderated mediation analysis.Results: PTG was positively correlated with creativity, self-efficacy, and deliberate rumination. Creativity was positively correlated with self-efficacy and deliberate rumination. Deliberate rumination was positively correlated with self-efficacy. Self-efficacy mediated the relationship between PTG and creativity. Deliberate rumination moderated the second half of the path of “PTG → self-efficacy → creativity.”Conclusions: PTG affected creativity directly and also indirectly through self-efficacy. In particular, deliberate rumination moderated the relationship between self-efficacy and creativity, such that the association was stronger when the incidence of deliberate rumination was low. These results provide a more comprehensive understanding of the positive link between PTG and creativity. (shrink)

We investigate the cross-correlations of return-volume relationship of the Bitcoin market. In particular, we select eight exchange rates whose trading volume accounts for more than 98% market shares to synthesize Bitcoin indexes. The empirical results based on multifractal detrended cross-correlation analysis reveal that the nonlinear dependencies and power-law cross-correlations in return-volume relationship are found; all cross-correlations are multifractal, and there are antipersistent behaviors of cross-correlation for q=2; the price of small fluctuations is more persistent than that of the volume, while (...) the volume of larger fluctuations is more antipersistent; and the rolling window method shows that the cross-correlations of return-volume are antipersistent in the entire sample period.

The aim of this study was to investigate the use of a newly developed design game called BLOCKS to stimulate awareness of ethical responsibilities amongst engineering students. The design game was played by seventeen teams of chemical engineering students, with each team having to arrange pieces of colored paper to produce two letters each. Before the end of the game, additional constraints were introduced to the teams such that they faced similar ambiguity in the technical facts that the engineers involved (...) in the Challenger disaster had faced prior to the space shuttle launch. At this stage, the teams had to decide whether to continue with their original design or to develop alternative solutions. After the teams had made their decisions, a video of the Challenger explosion was shown followed by a post-game discussion. The students’ opinion on five Statements on ethics was tracked via a Five-Item Likert survey which was administered three times, before and after the ethical scenario was introduced, and after the video and post-game discussion. The results from this study indicated that the combination of the game and the real-life incident from the video had generally strengthened the students’ opinions of the Statements. (shrink)

I focus on specific practices in twentieth- and twenty-first-century mathematics of articulating, barring, taming, and operating with what mathematicians widely call mathematical monsters. I describe how over centuries the quotidian procedures of the epitome of rational practice – mathematics – have produced beings outside the extant purified categories understood by theorems and proofs, despite, and sometimes as a consequence of, ever greater precision and rigor. However, mathematical monsters stand in a different relation to their makers than socio-economic and moral monsters (...) who are barred from the world. Indeed, we will see how mathematicians have made plural and productive accommodation with their monsters. Although some mathematicians have been persuaded by logicians to bar monsters from the temple of mathematics by simply forbidding the operations that engender beings against nature, most mathematicians have accommodated or simply cohabited with their monsters by extending axioms, definitions, theorems, and methods of proving theorems as a part of quotidianized practice.

Let ∃n denote the set of all formulas ∃x1…∃xn[P = 0], where P is a polynomial with integer coefficients. We prove a new relation-combining theorem from which it follows that if ∃n is undecidable over N, then ∃2n+2 is undecidable over Z.

Les questions les plus fondamentales de la phénoménologie du sentir de Max Scheler concernent la place de l’intentionnalité dans la phénoménologie du sentir et la structuration de la sphère émotionnelle. Dans la première section, nous nous focaliserons avant tout sur la différence entre les sentiments non intentionnels et le sentir intentionnel, en comparant sur ce point les positions de Scheler et de Husserl. En effet, Scheler critique ces deux thèses fondamentales de Husserl: 1) les actes affectifs et leurs corrélats (« (...) valeurs ») doivent être associés aux représentations et à leurs corrélats (« choses », Sachen ); 2) les actes affectifs, en tant qu’actes non objectivants, sont fondés dans les actes objectivants. D’une part, pour Scheler, la valeur est un objet unique en son genre du sentir des valeurs, et le sentir intentionnel est donc un acte indépendant. D’autre part, Scheler a d’abord entrepris de dépasser la séparation entre acte objectivant et acte non objectivant. Dans ce contexte, la recherche actuelle consacrée à Scheler se heurte à de nombreuses difficultés relatives à la structuration de la sphère émotionnelle en rapport avec la hiérarchie des modalités axiologiques et avec l’a priori corrélationnel. Dans la deuxième section, nous expliquerons d’abord les idées de Scheler, puis en discuterons les difficultés. C’est par le « commerce vivant » avec le monde dans le sentir intentionnel et dans les actes émotionnels intentionnels, par les corrélats intentionnels (valeurs matérielles), que Scheler se sépare du formalisme en éthique. A travers un « apriorisme matériel » qui présente trois espèce d’a priori (a priori axiologique, a priori émotionnel et a priori corrélationnel), l’éthique matérielle phénoménologique des valeurs de Sche­ler est guidée par l’esprit d’un « objectivisme et absolutisme éthique rigoureux ».

This study aimed to examine the integrated relationships of business ties, political ties, sustainable leadership, and frugal innovation. The correlation was assessed with the consideration of social network and situational leadership theories. Data was collected from 363 Small and Medium Enterprises employees in Pakistan with a response rate of 72.60%. Accordingly, the Partial Least Squares-Structural Equation Modeling was employed to examine the validity of the proposed hypotheses. Empirical findings confirmed the significant impact of managerial and business ties on frugal innovation, (...) strengthened by sustainable leadership. However, data analysis negated the positive impact of political ties on frugal innovation, which remains non-significant with the introduction of sustainable leadership among Pakistani SMEs. Hence, future studies are recommended to explore other conditional factors and mediating mechanisms in the relationship between managerial ties and frugal innovation. This idea can bring a deeper insight into the vital role of networking. To the best of the author’s knowledge, no prior study is available about the integrated relationships of managerial ties, frugal innovation, and sustainable leadership. This study enriches the literature in innovation management, especially concerning the social network and situational leadership model. (shrink)

In recent years, the method of the complex network has been applied to various fields. Dynamics research in complex networks is also an important branch. There are many types of research into dynamic complex network, but few scholars use bibliometrics to study it. Therefore, this paper adopts the method of bibliometrics to analyze the development history and status quo of dynamic complex network, providing a summary description of this research field. We used CiteSpace and Pajek to analyze 2936 relevant papers (...) on the website of Web of Science and further interpreted and summarized the analysis results. To fully show the bibliometric results, we further derive the productive countries, institutions, sources, and authors and some main research directions in the dynamic complex network research. The research results show that the dynamic complex network research method was applied to various fields after the dynamic research method had been integrated into the complex network. According to the subject analysis of the cited papers, we find that the dynamic complex network method has been widely used in various subjects. Through emergent analysis, we found that the latest hot research trends are the study of infectious diseases and applications in neural networks. At the same time, through the main path analysis, we find the essential literature to elaborate on the development context of a dynamic complex network at different time points. This paper gives a comprehensive analysis of dynamic complex network research and provides some enlightenment for the future research direction. (shrink)

On the one hand, Scheler's critique of Kant's concept of a priori benefits from Husserl to a large extent, and it complements and deepens Husserl's. On the other hand, Scheler also critiques Husserl's definition of a priori. Husserl's material a priori as ideal object primarily thanks to his so-called "Bolzano- turn". In this connection, Scheler grabs hold of the relation of Husserl to Bolzano from the very beginning. For Scheler, Husserl thinks in a "platonic" way, and still falls in a (...) new type of "Platonism", or rather, logical Platonism, although he correctly refuses the ordinary Platonism. In Scheler's view, Husserl's phenomenological reduction is "not purely" executed, and therefore his phenomenological experience is problematic, or more precisely, the relation between categorial intuition and sensuous intuition is problematic. The final aim of Scheler's critique of Husserl's phenomenological understanding of "objective a priori" is to win the primary position of categorial intuition and its content , ethical insight and its correlate , and ultimately of phenomenological ethics of material value.Einerseits nimmt Schelers Kritik an Kant bezüglich des Begriffs des Apriori die Einsichten Husserls in großem Umfang auf. Schelers Kritik an Kant ergänzt und vertieft die Husserlsche Kant-Kritik. Andererseits kritisiert er aber auch Husserls Bestimmung des Apriori. Vor allem verdankt sich das materiale Apriori als idealer Gegenstand bei Husserl der sogenannten “Bolzano’schen Wendung”. Von Anfang an kritisiert Scheler Husserl in diesem Punkt, indem er dem Verhältnis zwischen Bolzano und Husserl immer präziser nachging. Für Scheler unterliegt Husserl mit Recht keinem platten Platonismus. Aber dennoch verfahre Husserl immerhin “platonistisch”, er unterliege einem “Neoplatonismus”, bzw. einem logischen Platonismus. Weil die phänomenologische Reduktion bei Husserl nach Schelers Meinung “nicht reinlich” durchgeführt wird, ist die phänomenologische Erfahrung bei Husserl problematisch, genauer gesagt ist das Verhältnis zwischen der kategorialen Anschauung und der sinnlichen Anschauung problematisch. Der Endzweck von Schelers Kritik an der phänomenologischen Auffassung des gegenständlichen Apriori bei Husserl besteht darin, die primäre Stelle der kategorialen Anschauung und ihrer Gehalte , sowie der sittlichen Einsicht und ihrer Korrelate und zuletzt der phänomenologisch materialen Wertethik zu gewinnen.S jedne strane, Schelerova kritika Kantova pojma a priori u velikoj mjeri duguje Husserlu, te dopunjuje i produbljuje Husserlovu. S druge strane, Scheler kritizira i Husserlovu definiciju apriorija. Husserlov materijalni a priori kao idealni predmet prvenstveno proizlazi iz njegova takozvanog bolzanovskog obrata. Prema Scheleru, Husserl razmišlja na "platonski" način te upada u novi tip "platonizma" ili, točnije, logičkog platonizma, iako s pravom odbacuje obični platonizam. Scheler smatra da Husserlova fenomenološka redukcija nije izvedena "čisto" te da je stoga njegovo fenomenološko iskustvo proble- matično ili, točnije, problematičan je odnos između kategorijalnog zora i osjetilnog zora. Krajnji cilj Schelerove kritike Husserlova fenomenološkog shvaćanja "objektivnog a priori" jest zadobivanje primarne pozicije kategorijalnog zora i njegova sadržaja , etičkog uvida i njegova korelata te, na koncu, fenomenološke etike materijalne vrijednosti.

Liver transplantation (LT) activities during the COVID-19 pandemic have been curtailed in many countries. The impact of various policies restricting LT on outcomes of potential LT candidates is unclear. We studied all patients on the nationwide LT waitlists in Hong Kong and Singapore between January 2016 and May 2020. We used continuous time Markov chains to model the effects of different scenarios and varying durations of disruption on LT candidates.

Using the promulgation of Green Credit Guidelines in China as the research setting, this paper exploits a quasi-natural experiment to examine the impact of green credit policy on the stock price crash risk of heavy-polluting firms. The results show that green credit policy significantly increases the risk of stock price crash of heavy-polluting firms. Such impact is transmitted through increased financial constraints and reduced information transparency. In addition, we find that the impact of green credit policy on the stock price (...) crash risk is more pronounced in firms with weak external governance and a small size. Our findings provide policy implications for mitigating corporate risks and promoting corporate sustainability. (shrink)

The Dutch Book Argument shows that an agent will lose surely in a gamble (a Dutch Book is made) if his degrees of belief do not satisfy the laws of the probability. Yet a question arises here: What does the Dutch Book imply? This paper firstly argues that there exists a utility function following Ramsey’s axioms. And then, it explicates the properties of the utility function and degree of belief respectively. The properties show that coherence in partial beliefs for Subjective (...) Bayesianism means that the degree of belief, representing a belief ordering, satisfies the laws of probability, and that coherence in preferences means that the preferences are represented by expected utilities. A coherent belief ordering and a utility scale induce a coherent preference ordering; a coherent preference ordering induces a coherent belief ordering which can be uniquely represented by a degree-of-belief function. The preferences (values) and beliefs are both incoherent or disordered if a Dutch Book is made. (shrink)

This article investigates an adaptive neural network control algorithm for marine surface vessels with time-varying output constraints and unknown external disturbances. The nonlinear state-dependent transformation is introduced to eliminate the feasibility conditions of virtual controller. Moreover, the barrier Lyapunov function is used to achieve time-varying output constraints. As an important approximation tool, the NN is employed to approximate uncertain and continuous functions. Subsequently, the disturbance observer is structured to observe time-varying constraints and unknown external disturbances. The novel strategy can guarantee (...) that all signals in the closed-loop system are semiglobally uniformly ultimately bounded. Finally, the simulation results verify the benefit of the proposed method. (shrink)

The concept of a priori plays an important role in Kant’s entiree philosophy. However, Husserl often claimed that a genuine concept of a priori in the phenomenological sense was absent in Kant. Scheler criticized this concept of Kant just as Husserl did. All of Scheler’s ethical critiques of Kant, who is the major opponent to Scheler, are based on his critiques of Kant’s concept of a priori because, for Scheler, it is the largest absurdity of Kant’s theory that a priori (...) is equated to the formal. Scheler thus clearly delineated Kant’s transcendentalism, which seeks a priori in form. It seems that Scheler‘s comprehension and interpretation of a priori reversed Kant’s “Copernican revolution”, in contrast with which, Scheler carried ou a „Ptolemiac counter-revolution“. In fact, Scheler questioned Kant‘s transcendental-rational theory of the function of synthetic categories, which derived from the “Copernican revolution”. Nevertheless, Scheler did not want to defend the pre-Kant position, or Kant’s pre-critique period. He also did not mean simply to stress one side in Kant’s dualism, which was ignored by Kant. In fact, he wanted to question Kant’s metaphysical dualism itself. The eventual goal of his phenomenological philosophy is to reveal the uncritical presuppositions in Kant’s critical philosophy.

The use of comparative methods to study in China since reform and opening up and development of higher education faces challenges and opportunities. Pointed out: At present, China's higher education development to a new stage and critical period, opportunities and challenges, we must establish and implement the scientific concept of development, people-oriented, co-ordination of higher education and economic development of the coordinated development of the connotation and extension of the coordinated development of Road, correctly grasp the scale and quality of (...) the dialectical relationship between the advance of different types, levels, ownership and coordination of higher education in the development of different regions. The development of higher education in China has reached a new and crucial stage currently, facing both opportunities and challenges. We must establish and implement a scientific concept of development, which is human-oriented. By both intensive form and extensive form, the increasing speed of the scale of higher education should be coordinated with that of economic development. The dialectical relationship between the scale and quality has to be mastered. The development of different types, levels, ownerships and regions of higher education should be coordinated and balanced. (shrink)

The dissertation project is a study of the rhetoric of "enlightenment" and the philosophy of modernity. It addresses two seemingly unrelated questions: "what is enlightenment?" and "what is May Fourth?" The investigation of these two questions is located in the contexts of Kant-Foucault-Habermas's dialogue on "what is enlightenment?" and Western sinology's re-presentation of Chinese modernity. One of the objectives of the present study is to critique modern sinology's re-presentation of Chinese modernity, which has reduced the latter into a latent statement (...) of the Enlightenment and a derivative language of Reason, and hence, to seek to determine the conditions of possibility to address the question of "what is May Fourth?" ;The study attempts to identify the problematics in the Kant-Foucault-Habermas context, in which enlightenment was treated as an enterprise to bridge the gap between theoretical reason and practical intelligence, reason and unreason, and expert knowledge and everyday praxis. The study suggests that mediation of hermeneutic understanding of text/tradition with political commitment to organize an enlightened society was treated differently in Confucian and modern Chinese political philosophy and historiographical discourse. Examination of that treatment, the study points out, may help provide a framework to further reflect upon some unresolved problems and anticipate some pratical difficulties in the Western genealogy of enlightenment.

Although research in the feedback-seeking behavior literature has primarily focused on feedback-seeking from supervisors, some emerging works have begun to explore the benefits of coworker feedback-seeking behavior. Based on the social exchange theory, we investigated how and when seeking feedback from coworkers will benefit the seekers. Using a sample of 327 teachers from China, we find that seeking feedback from coworkers is positively associated with task performance and workplace well-being. Seeking feedback from coworkers is also positively associated with coworker relationship. (...) Moreover, the coworker relationship mediates the effects of seeking feedback from coworkers and task performance and workplace well-being, and moderates the strength of the relationship between seeking feedback from coworkers on task performance and workplace well-being. Theoretical and practical implications of our findings are discussed. (shrink)

The problem of self-consciousness has been an essential one for philosophy since the onset of modernity. Both E. Tugendhat and the Heidelberg School represented by D. Henrich have reflected critically upon the traditional theory of self-consciousness, and both have revealed the circular dilemma of the “reflection-model” adopted by the traditional theory. In order to avoid the dilemma, they both proposed substitute formulas, each of which has its advantages and disadvantages. Husserl also paid particular attention to the traditional theory of self-consciousness (...) in his phenomenology. Through the distinctions of “primal consciousness” and “reflection,” Husserl explored the core problem of the traditional theory of self-consciousness in two different dimensions. In his critique, Husserl clarified the founding relation between primal consciousness and reflection, and in contrast to Tugendhat’s semantic approach, he developed a new reflection-model of self-consciousness which effectively avoids the circular dilemma of the traditional theory and does not narrow the problem domain of that theory.
