To explore the number of latent variables underlying recognition of own- and other-race faces for Chinese observers, we conducted a study-recognition task where orientation, stimuli type, and duration were manipulated in the study phase and applied state trace analysis as a statistic method. Results showed that each state trace plot on each pair of stimuli types matched a single monotonic curve when stimuli type was set to state factor, but separate curves between face and non-face showed up when the state factor was orientation. The results implied that at least two latent variables affected recognition performance in the inversion paradigm. Besides, the unidimensional structure between own- and other-race faces regardless of the state factor suggested that Chinese participants used the same recognition mechanism for unfamiliar own- and other-race faces in the inversion paradigm.

By investigating the status quo of the swimming training market in a certain area, we can obtain information on the current development of the swimming training market in a certain area and study the laws of the development of the market so as to provide a theoretical basis for the development of the market. This paper designs an evaluation algorithm suitable for swimming training based on the improved AlexNet network. The algorithm model uses a 3 × 3 size convolution kernel to extract features, and the pooling layer uses a nonoverlapping pooling strategy. In order to accelerate the network convergence, the model introduces batch normalization technology. The algorithm uses data augmentation technology to expand the data set, including rotation and random erasure, to a certain extent alleviating the problem of overfitting. The results of the study showed that there were no significant differences in fat, minerals, protein, body mass index, basal metabolic rate, and total energy expenditure in the body composition ratios of children in the convolutional neural network assessment group and the control group, while muscle and total body water were not significantly different. However, there are significant differences in fat-free body weight and muscle strength of various segments of the body, among which there are very significant differences in muscle strength of lower limbs in each segment of the body. There were no significant differences in minerals, body mass index, basal metabolic rate, total energy expenditure, and lower limb muscle strength in the body composition ratios of men and women in the convolutional neural network assessment group. There are significant differences in body weight, upper limb muscle strength, and trunk muscle strength. There were no significant differences in the proportions of body composition between men and women in the control group, except for fat and protein.

Based on learning, thinking, practicing and understanding, this paper explores the main ideas of the ideological and political construction of college mathematics courses under the blended learning model, which are mainly carried out from four aspects: the construction of knowledge system, the transformation of teaching concept, the promotion of blended learning model and the reform of evaluation method. Besides, it also carries out a specific case analysis and gives ways to achieve a good teaching effect.

BackgroundUsing Bourdieu’s cultural capital theory, this paper discusses the inequality of Chinese urban residents’ participation in physical activities caused by cultural capital and explores the relationship and role of residents’ income and self-rated health in cultural capital and physical activity participation.MethodsUsing Chinese social survey data, the proposed assumptions were tested and analyzed by using a linear regression model.ResultsCultural capital can promote the participation of Chinese urban residents in physical activities, and personal income and health self-assessment play an intermediary role in promoting residents’ participation in physical activities.ConclusionPromoting Chinese residents’ participation in physical activities can be realized not only through traditional publicity and sports venue construction but also by increasing residents’ educational level, art appreciation level and health awareness.

Development of economic globalization and integration of resources to promote cross-border flows of insurance, international insurance activities of transnational norms and ensure that the international insurance market operation order and national stability and development of the insurance industry the legal system - the International Insurance Act, under international law system derived emerging legal discipline. International Insurance Act of generation is a necessary requirement for development of the times. Study of international insurance law, should clarify the "International Insurance" phenomenon and the "International Insurance Law" to start understanding, revealing the international insurance and related legal emergence and development of the times and world economic developments. On this basis, by analyzing the definition of the basic concepts of international insurance law and nature of international economic law at the international insurance system under the legal research tasks and content, for the enrichment and development of norms of international economic activity and content of international economic law system has laid the theoretical study basis. Legal research by revealing the state of international insurance and challenges, thereby contributing to international research and development of the insurance law. The International Insurance Law, a new rising law subject which governing the cross-bonier insurance activities and assuring the moving order of international insurance market and insurance industries in varies countries, comes out under the developing environment of economic globalization and integration that promotes the cross- border movement of insurance resources. From clarifying the phenomena of 'International Insurance' and 'International Insurance Law', this paper mainly focuses on the analysis on the following issue: the concept and nature of International Insurance Law, the study mission and contents of the subject of International Insurance Law, and expounds the study status of the subject of International Insurance and challenges facing, thus promoting the development of the subject of International Insurance

Tang Dynasty in ancient China made ​​remonstrance the maturity period of institutional development, in particular, to become scholars admonish Emperor Zhen Guan Zheng phase interference in domestic affairs of the golden age. Appeal based on age, Tang Zheng scholars with a strong sense of remonstrance, in order to correct the error king, they boldly made ​​the bridge, and fear of punishment Wei, and sometimes even at the cost of life. The remonstrance Zheng Tang scribes not only the spirit and political lives, but also for literary realist tendency to produce a very profound impact. The remonstrant system in ancient China had been matured in Tang dynasty especially during the Zhenguan period. Therefore, the gentry were audacious to make remonstrance to correct the emperors' mistakes without fearing penalty even losing their lives, which was related to politics and had made heavy influence on literature in Tang dynasty
