Measurement and Evaluation of the Business Environment in Large and Medium-Sized Cities in China

The comprehensive development level of the business environment reflects the quality of a region’s economic development,and a good business environment will give a city a strong vitality.This paper uses the entropy method to measure and evaluate the business environment of 106 large and medium-sized cities in China from 2017 to 2021.The results show that:From the spatial point of view,the business environment index of China’s cities shows a gradually decreasing pattern from east to west and from south to north.The balance of the business environment of large and medium-sized cities in China is divided into four levels according to the standard deviation of the ranking of each subindex.The greater the standard deviation,the more unbalanced the overall development of the business environment in the region.Finally,this paper put forward countermeasures and suggestions to further optimize the business environment.

Research on the influence of quadrupole deformation and continuum effects on the exotic properties of 15,17,19B with the complex momentum representation method

The properties of exotic nuclei are the focus of the present research.Two-neutron halo structures of neutron-rich17,19B were experimentally confirmed.We studied the formation mechanism of halo phenomena in17,19B using the complex momentum representation method applied to deformation and continuum coupling.By examining the evolution of the weakly bound and resonant levels near the Fermi surface,s–d orbital reversals and certain prolate deformations were observed.In addition,by analyzing the evolution of the occupation probabilities and density distributions occupied by valence neutrons,we found that the ground state of15B did not exhibit a halo and the ground states of17B and19B exhibited halos at 0.6≤β2≤0.7 and0.3≤β2≤0.7,respectively.The low-l components in the valence levels that are weakly bound or embedded in the continuous spectrum lead to halo formation.

Interpretation of the Characteristics of the Southern Anhui Third Front Industrial Cultural Landscape in the Context of Philosophy of Technology

The third front industrial cultural landscape has the dual attributes of “industry” and “nature”.The special historical background and mountainous environment make it a distinctive industrial cultural landscape.Taking the third front industrial cultural landscape of southern Anhui as an example,this paper uses philosophy of technology to study this industrial cultural landscape with “modernity” characteristics,so as to make its “culture” return to the industrial cultural system and rethink,rather than the previous interpretation in the context of “cultural relics”.Then,under the framework of natural system,technological system and cultural system,the deep-seated cultural philosophy characteristics of the third front industrial cultural landscape are explained from the technological nature of the three line industrial cultural landscape.

Exploring the impacts of major events on the systemic risk of the international energy market

This study examines the systemic risk caused by major events in the international energy market(IEM)and proposes a management strategy to mitigate it. Using the tail-event driven network(TENET)method, this study constructed a tail-risk spillover network(TRSN) of IEM and simulated the dynamic spillover tail-risk process through the cascading failure mechanism. The study found that renewable energy markets contributed more to systemic risk during the Paris Agreement and the COVID-19pandemic, while fossil energy markets played a larger role during the Russia-Ukraine conflict. This study identifies systemically important markets(SM) and critical tail-risk spillover paths as potential sources of systemic risk. The research confirms that cutting off the IEM risk spillover path can greatly reduce systemic risk and the influence of SM. This study offers insights into the management of systemic risk in IEM and provides policy recommendations to reduce the impact of shock events.

Changing Characteristics of Comfort Index of Human Body in Bengbu City in the Past 40 Years under the Background of Climate Change

Based on the daily meteorological data of Bengbu City during 1981-2020,the changing characteristics of three elements needed for the calculation of the comfort index of human body(CIHB)were discussed,and daily CIHB was classified and discussed.The results show that from 1981 to 2020,annual average temperature tended to increase significantly.Annual average wind speed and relative humidity showed a decreasing trend before 2011 but an increasing trend after 2011.The duration of the four seasons in Bengbu City mainly rose in spring,reduced in winter,declined first and then increased in summer,and rose first and then decreased in autumn.As CIHB was at grades 1 and 9(the most uncomfortable),the three factors had different effects on them.For cold weather,the influence of relative humidity and wind speed on CIHB can not be ignored besides temperature.In hot weather,the influence of temperature was dominant,and the change of annual average temperature could well correspond to the change in the number of very hot days.In the context of climate warming,the number of cold days tended to decline generally,but it was larger in the years with fewer very cold days.Under the background of climate warming,there was no obvious change in the number of days of the overall comfort of human body.The number of hot days was closely related to the duration of summer,and the number of days of grade 8 rose significantly in the years with an increase in the duration of summer.

Current Situation of College Students’ Entrepreneurship and Employment in the Countryside in the Context of Rural Revitalization

Focusing on the talent training in the strategy of revitalizing the countryside, this paper uses questionnaire survey, field survey, descriptive statistics, chi-square test and other methods to study the willingness of college students to "go to the countryside" to contribute to rural development after graduation, as well as the influencing factors. The results show that the willingness of college students to "go to the countryside" is negative after graduation, and engaging in rural education and returning to their hometown to start a business is the mainstream will of college students to "go to the countryside". The one-sidedness of the understanding of rural areas, less employment opportunities, low wages, poor infrastructure conditions and the views of the older generation are the important reasons that hinder college students from "going to the countryside". The good environment in rural areas and the guidance of policies are the biggest promoting factors for "going to the countryside". The willingness of rural college students to "go to the countryside" is significantly higher than that of urban college students. The freshman s willingness to "go to the countryside" is the most positive, and the graduate students willingness to "go to the countryside" is the most negative. The college students majoring in agriculture are most willing to support the development of rural areas, while the students of "medicine","literature" and "art" are most unwilling to "go to the countryside". Whether or not to participate in the "volunteer activities for the country people" has no impact on the willingness to "go to the countryside".

Dynamics of a Delayed Predator-prey System with Stage Structure for Predator and Prey

In this paper, a predator-prey system with two discrete delays and stage structure for both the predator and the prey is investigated. The dynamical behaviors such as local stability and local Hopf bifurcation are analyzed by regarding the possible combinations of the two delays as bifurcating parameter. Some explicit formulae determining the direction of the Hopf bifurcation and the stability of the bifurcating periodic solutions are derived by using the normal form method and the center manifold theory. Finally~ numerical simulations are presented to support the theoreticM analysis.

Hopf Bifurcation of Delayed Predator-prey System with Reserve Area for Prey and in the Presence of Toxicity

A kind of three species delayed predator-prey system with reserve area for prey and in the presence of toxicity is proposed in this paper. Local stability of the coexistence equilibrium of the system and the existence of a Hopf bifurcation is established by choosing the time delay as the bifurcation parameter. Explicit formulas to determine the direction and stability of the Hopf bifurcation are obtained by means of the normal form theory and the center manifold theorem. Finally, we give a numerical example to illustrate the obtained results.

Modeling of unsupervised knowledge graph of events based on mutual information among neighbor domains and sparse representation

Text event mining,as an indispensable method of text mining processing,has attracted the extensive attention of researchers.A modeling method for knowledge graph of events based on mutual information among neighbor domains and sparse representation is proposed in this paper,i.e.UKGE-MS.Specifically,UKGE-MS can improve the existing text mining technology's ability of understanding and discovering high-dimensional unmarked information,and solves the problems of traditional unsupervised feature selection methods,which only focus on selecting features from a global perspective and ignoring the impact of local connection of samples.Firstly,considering the influence of local information of samples in feature correlation evaluation,a feature clustering algorithm based on average neighborhood mutual information is proposed,and the feature clusters with certain event correlation are obtained;Secondly,an unsupervised feature selection method based on the high-order correlation of multi-dimensional statistical data is designed by combining the dimension reduction advantage of local linear embedding algorithm and the feature selection ability of sparse representation,so as to enhance the generalization ability of the selected feature items.Finally,the events knowledge graph is constructed by means of sparse representation and l1 norm.Extensive experiments are carried out on five real datasets and synthetic datasets,and the UKGE-MS are compared with five corresponding algorithms.The experimental results show that UKGE-MS is better than the traditional method in event clustering and feature selection,and has some advantages over other methods in text event recognition and discovery.

Analysis of Colors of Ancient Villages in Jiangsu-Anhui Region Based on Cultural Connotation

Colors of ancient villages in Jiangsu-Anhui Region are of classic beauty and in elegant taste,representing a neutral color system composed of 3 kinds of lightness,namely black,white,and gray.The formation of that feature is closely related with the development of feudal society in China as well as the natural environment and folk culture of Jiangsu-Anhui Region.This paper analyzed the cultural connotation reflected by the colors of the ancient villages in Jiangsu-Anhui Region,explored the causes of its colors in terms of ancient law,regional exchange,and customs in that region,and revealed the historical context and cultural characteristics of the ancient villages south of the Yangtze River,so as to provide a frame of reference for the protection and development of historical and cultural heritage in the ancient villages.

Technological Content of the Import of Services and the Transformation of Growth Patterns of China's Industrial Economy

Based on the latest approach for measuring technology content of import of services and with the contribution of total factor productivity(TFP) to gross industrial output as the indicator for measuring the growth pattern of China's industrial economy,this paper provides an empirical study on the effect of import technology content of trade in services on the development pattern of China's industrial economy between 2004 and2011.Result of econometric test reveals that the technology content of import of services has a significant positive effect on transforming the growth pattern of China's industrial economy.Moreover,import of new types of trade in services with high technology such as computer and information services has a much stronger positive effect compared with import of traditional trade in services with relatively low technology content such as transport.In terms of different industrial sectors,technology content of import of services has the greatest effect on transforming the development pattern of China's technologyintensive industrial sectors,followed by capital-intensive,resource-intensive and laborintensive sectors respectively.Transformation of the development pattern of China's industrial economy cannot be isolated from the system of global division of work.Against the backdrop of global service sector fragmentation,China should take the important opportunities in the development of global trade in services and give more attention to improving the quality of import of services in the interest of transforming the development pattern of its industrial economy.

New Agricultural Business Entity and Rural Governance Body against the Backdrop of Rural Revitalization

The new agricultural business entity is the representative of the "new" productive forces in the countryside. Based on the analysis of the connotation of the new agricultural business entity, this paper further explains the new characteristics of the new agricultural business entity, such as internationalization, informatization, greening, ecologization, and organizational integration. The new type of agricultural business entity is the innovation of socialist agricultural management system with Chinese characteristics, which has brought new institutional performance to agricultural and rural modernization, and caused changes in the rural governance body and its structure in terms of production relations. The traditional basic subject "villager" has changed to "professional farmer", "homogenization" to "heterogeneity" and "diversification", and governance pattern to "unitary leading and pluralistic participation". These developments and changes reflect the dialectical relationship movement between rural productive forces and production relations, economic base and superstructure. New agricultural business entity, rural governance body and their structural system have become an important basis for rural revitalization.

Wildean Ambivalent Dichotomy of Women--Taking An Ideal Husband as An Example

Oscar Wilde is mainly famous for being the representative figure of Aesthetic Movement and the steadfast advocate of"art for art's sake". Although being influenced by the traditional dichotomy of women, Wilde does try to add some personal elements during this process. In one of his social comedies, An Ideal Husband, this wildean characteristic is more obvious. This essay attempts to reveal those hidden images which are employed by Wilde to represent his female characters and tries to show the Wilde's improvement of the traditional dichotomy.
