A data-enhanced distributionally robust optimization method for economic dispatch of integrated electricity and natural gas systems with wind uncertainty

Cultural education is the concept of college English culture teaching, and college English teaching is an effective way to implement the concept of cultural education. At present, there are still many problems in college English teaching, such as the lack of cultural education, single teaching objectives, lack of teaching strategies and imperfect evaluation system. In view of these problems, this article puts forward the research on the reform of college English education inspired by the cultural differences between China and the United States. First, this study was carried out to understand the differences between Chinese and American cultures and clarify the current situation of college English education. Then, the matrix-valued factor model is constructed to identify the feature vector of cultural differences, decompose the features of cultural differences, obtain the feature vector corresponding to the maximum feature value and predict the covariance matrix. The model effectively reduces the matrix dimension, greatly reduces the number of expected parameters, effectively prevents the accumulation of estimation errors and further clarifies the dependence between covariance matrix elements through coefficient analysis. Finally, the VaR identification model can predict the development trend of college English education reform. The experimental results show that this method can effectively improve college students’ English performance and teachers’ teaching quality and has wide applicability.

“…coefficient matrix and e is the cultural difference vector [22]. It can be concluded that the prediction matrix-valued factor model is as follows:…”

“…Looking at the current situation of my country's agricultural development, it has the disadvantages of starting late with a relatively weak development level. The shortcomings of agricultural modernisation development directly drag down the overall process of my country's 'four modernisations' [2], Against the background of such a development environment, in order to make up for the insufficiency of agricultural development, the 19th National Congress of the Communist Party of China proposed a rural revitalisation strategy [3], adhering to the priority development of agriculture and rural areas [4]. The general requirements for effective governance and a prosperous life [5], establish and improve the urban-rural integrated development system [6] and policy system [7] and accelerate the modernisation of agriculture and rural areas.…”

Analysis of agricultural economic development and optimisation measures under the strategy of rural revitalisation

In order to better promote economic development, my country has successively issued many preferential policies, which have created more and better opportunities for economic development and the improvement of comprehensive national strength. My country's agricultural development has more development momentum and long-term planning goals. This paper firstly sorts out the practical and theoretical significance of implementing the rural revitalisation strategy. Based on doing a good job in agricultural economic management, when conducting cointegration analysis, the stationarity of the time series is tested, and an error correction model (ECM) is introduced as a supplement. It lays foundation for the analysis of optimisation measures; secondly, the ADF test is carried out for the constructed ECM, and the entropy method and the analytic hierarchy process are used to calculate various indicators. Finally, according to the numerical results obtained, the agricultural economy under the rural revitalisation strategy is completed. The analysis of development and optimisation measures can fundamentally solve the limitations of the concept of rural development, break through the shackles of traditional development models, explore a path more suitable for the development of new rural areas and new agricultural economy and fundamentally improve the quality of production and life of farmers.

“…This very broad concept of commodity quality also confuses the direction and focus of scientific research to a certain extent. The research on the influence mechanism of brand development and consumption in China is mostly focussed on the stage of shopping and not buying, and the research tackles various issues [12]. In addition, some research results on customer buying process mainly focus on the positive effect or proof of social and historical factors on customer's buying behaviour [13].…”

Research on the post-purchase behaviour tendency of the product quality to customers in fast-selling marketing

2022

Based on an analysis of the influence of the quality of fast-selling products on customers' shopping behaviour, this paper discusses the research on the influence of various factors on customers' shopping behaviour. According to modern scientific methods and literature, theoretical research and social factor analysis, from three angles, namely corporate image, product/service image, and consumer image, six important indicators, such as corporate image, product style and value, consumer characteristics, user's buying feeling, corporate philosophy and corporate values, are determined, which are the key factors that influence people's choice behaviour. Considering the key factors in the quality of fast-selling products and the weight of their influence on users' choice behaviour, according to the development trend of the fast-selling-product industry, this paper provides appropriate guidance on shaping and ensuring the quality of enterprises' products. Suggestions on image-building and maintenance of fast-selling products are as follows: the image-building of fast-selling products must pay attention to quality, the shaping of brand culture and the practice of brand image communication management.
