In the background of the environment of economic globalization, the strengthening of China's economic strength, comprehensive national power, the development of the national economy, is the cross-border e-commerce has been widely developed, cross-border e-commerce of overseas exchanges more and more frequent. This form of trade has also facilitated people's lives to a certain extent, while bringing economic benefits to many enterprises, reducing the difficulties of enterprises and customers brought about by geography and making transactions more convenient. This form of trade also has an impact on the macroeconomic economy of the country and accounts for a large proportion of the social economy. Economic globalisation is the process by which the world's economic activities transcend national borders and form a global organic economic whole through foreign trade, capital flows, technology transfer, service provision, interdependence and interconnectedness. And in the context of economic globalisation, the world is witnessing increasingly close trade exchanges, the emergence of multinational enterprises, cross-border e-commerce and a range of economies, where companies from various countries are beginning to face the world and where companies from various countries are competing and cooperating with each other. International trade is becoming more and more popular and developed, and in this general environment, the economies of various countries around the world have been affected to some extent, and cross-border e-commerce is an adaptation to this general environment.

Under the rapid development of the economy and society, the development process of the financial sector is also accelerating now. Nowadays, a variety of financial data information is emerging, how to fully combine these big data with the financial field is the key topic of general concern in the financial field, the combination of the two can make effective use of various financial data, so as to promote the healthy and sustainable development of the entire financial field. Therefore, this paper focuses on the specific application of computer big data in the field of finance, which has practical significance.

Cation-chloride cotransporters (CCCs) regulate the movement of chloride across membranes, controlling physiological processes from cell volume maintenance to neuronal signaling. Human CCCs are clinical targets for existing diuretics and potentially additional indications. Here, we report the X-ray crystal structure of the soluble C-terminal regulatory domain of a eukaryotic potassium-chloride cotransporter, Caenorhabditis elegans KCC-1. We observe a core α/β fold conserved among CCCs. Using structure-based sequence alignment, we analyze similarities and differences to the C-terminal domains of other CCC family members. We find that important regulatory motifs are in less-structured regions and residues important for dimerization are not widely conserved, suggesting that oligomerization and its effects may vary within the larger family. This snapshot of a eukaryotic KCC is a valuable starting point for the rational design of studies of cellular chloride regulation.

China has modified its pollution control policy system with such price tools as the pollution charge (PC) policy and the payment for initial emission allowance (PIEA) policy. The aim of PC policy is to compensate for the environment damage caused by pollutants, while PIEA is in charge of the initial emission allowance (IEA) within the emission trading system (ETS). However, since the implementation of PIEA, it has been criticized as redundant because of the similar pricing scheme with the PC. In addition, the existing PIEA pricing approaches have ignored interactions with other policies, such as PC and total emission control (TEC) policies. In this research, we established an optimal control-based model with chemical oxygen demand (COD) and ammoniacal nitrogen (NH3-N), two independent pollutants variables, to simulate the water pollutants' PIEA price. Simulation results indicated that emission quantity and optimal social benefit in the PC–PIEA combination scenario was equal to the situation in the PIEA scenario. Under this design, PC compensated for the emission damage, and PIEA paid for the scarcity rent, while PIEA does not duplicate the PC policy. In addition, the PIEA policy has a complex effect on pollutant emission. Because PIEA policy increases the enterprises' discharging cost, most regions' COD emissions are less than the baseline, excepting Beijing, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong, and Guangdong, in which emission quantities are greater than the baseline. The NH3-N emission shows an opposite trend. The simulation result is that excluding Inner Mongolia, Hubei, Hunan, Tibet, Gansu, Qinghai, Ningxia, and Xinjiang, the NH3-N emissions in the rest of regions are increased. TEC policy has a significant effect on pollutant emissions and the PIEA price. The COD emission quantity with TEC is lower than that without the TEC policy, therefore, the TEC policy will be effective for pollutant emission control. The pollutant beyond the restricted target will be charged a payment for IEA at a higher price than without the TEC policy.

O presente estudo insere-se num campo de estudos interdisciplinar, envolvendo principalmente duas culturas, dois sistemas sociais, dois sistemas filosóficos, duas modalidades artísticas, dois espaços de investigação, e visa responder às seguintes questões: (i) como é que os portugueses compreendiam a cultura chinesa no século XVII e (ii) como é que essa compreensão influenciou a criação artística portuguesa, sobretudo a manufatura da faiança portuguesa naquela época? A partir de um corpus de peças de faiança portuguesa do século XVII com temas de inspiração chinesa existentes em museus públicos e em coleções privadas e mediante a comparação dialética e hermenêutica das narrativas culturais chinesas presentes na faiança portuguesa e na porcelana chinesa, é possível atingir uma compreensão cultural baseada numa perspetiva global. O estudo é constituído pelo estudo dos motivos animais, vegetalistas, de figura humana, shanshui, arquitetónicos e gráficos. Os resultados obtidos nesta pesquisa pretendem fortalecer o estudo da faiança portuguesa do século XVII por meio do aprofundamento de estudos anteriores. Desta forma, pretende-se contribuir para a renovação das teorias dos estudos culturais e das relações internacionais em termos de diálogos e influências entre o Oriente e o Ocidente, a fim de fortalecer o desenvolvimento contínuo das compreensões interculturais. The present study is situated within an interdisciplinary realm of research, involving mainly two cultures, two social systems, two philosophical systems, two artistic modalities, two investigation spaces, aiming to answer the following questions: (i) how did the Portuguese understand Chinese culture in the 17th century and (ii) how did this understanding influence Portuguese artistic creation, especially the manufacture of faience in those times? Cultural understanding based on a global perspective was achieved by means of the organization of a corpus of 17th century Portuguese faience pieces with Chinese-inspired themes which are held in public museums or private collections as well as the dialectic and hermeneutic comparisons of the Chinese cultural narratives present in Portuguese faience and in Chinese porcelain. This study is composed of animal motifs, vegetalist motifs, human figure motifs, shanshui motif, architectural motifs and geographical motifs. The results obtained in this research introduce new energy in in the study of 17th century Portuguese faience by means of the identification of undetermined or ambiguous findings of previous studies. Thus, they contribute to the renewal of cultural studies theories and international relations in terms of dialogs and influences between East and West with the aim to strengthen the ongoing development of intercultural understanding.

In both theoretical and practical senses, Gothic writing techniques and Yin-Yang theory share many similarities. To some extent, Gothic writing techniques can be explained by Yin-Yang theory and their application in Gothic fictions can be transferred to corresponding regulations in Yin-Yang theory. This paper mainly looks into the similarities and dissimilarities of them, specifically in Edgar Allen Poe’s The Fall of the House of Usher. This paper studies this two terms from a philosophical perspective.
