The sampling-based motion planner is the mainstream method to solve the motion planning problem in high-dimensional space. In the process of exploring robot configuration space, this type of algorithm needs to perform collision query on a large number of samples, which greatly limits their planning efficiency. Therefore, this paper uses machine learning methods to establish a probabilistic model of the obstacle region in configuration space by learning a large number of labeled samples. Based on this, the high-dimensional samples’ rapid collision (...) query is realized. The influence of number of Gaussian components on the fitting accuracy is analyzed in detail, and a self-adaptive model training method based on Greedy expectation-maximization algorithm is proposed. At the same time, this method has the capability of online updating and can eliminate model fitting errors due to environmental changes. Finally, the model is combined with a variety of sampling-based motion planners and is validated in multiple sets of simulations and real world experiments. The results show that, compared with traditional methods, the proposed method has significantly improved the planning efficiency. (shrink)

Objective: To investigate the relationship between psychological empowerment, psychological capital, job involvement, and the retention intention of kindergarten teachers in mainland China and the internal mechanism of action.Methods: A total of 554 kindergarten teachers were investigated by scales for psychological empowerment, psychological capital, job involvement, and retention intention.Results: Psychological empowerment was positively correlated with psychological capital and job involvement. Psychological capital was positively correlated with job involvement. Psychological empowerment, psychological capital, and job involvement were significantly and positively correlated with retention (...) intention. Psychological empowerment influences kindergarten teachers' retention intention mainly through three indirect effects: the single intermediary effects of psychological capital and job involvement and the chain intermediary effect of psychological capital → job involvement.Conclusion: Psychological empowerment can not only indirectly predict the retention intention of kindergarten teachers through the single intermediary effects of psychological capital and job involvement, but also indirectly predict the retention intention of kindergarten teachers through the chain intermediary effect of psychological capital and job involvement.

Zha Changping takes inspiration from Western art theories and applies them to a contemporary Chinese context. The article has an ontological perspective, discussing how the concept of “relational aesthetics” manifests in Chinese contemporary art. It also discusses its relation to the history of ideas. The focus is on art, but the ontological perspectives on creation and humanity are universal.

The present text addresses the following questions: Why is the history of ideas in pioneering contemporary Chinese art essentially a history of culture? Why and how is art a kind of historical cultural phenomenon? What kind of challenges will artistic production encounter in the course of China’s civilizational transformation, and which artworks testify to these? These queries constitute the central focus of the history of ideas in pioneering art understood as a history of culture.

This paper presents the philosophical and theological underpinnings of the so-called “world-picture logic” mode of critique. It also outlines the arguments—empirical, transcendental and creationist—upon which the aesthetic framework depends that has the world relational picture as its object. By laying out these arguments and inquiring into the nature of what is human, it sketches the relational theology central to the “world-picture logic” mode of critique.

The changing context and increasing professionalization in higher education have ushered in challenges for liberal arts education worldwide. Situated this discourse in the context of Chinese universities, this paper explores Why do we need a liberal arts education that has been accused of being elitist in the twenty first century? Should an effective or ideal liberal arts education evolve with time and context? If yes, what needs to be taken into account to conceptualize a twenty first century model of liberal (...) arts education? How is a twenty first century liberal arts education defined and featured at Chinese universities and elsewhere? Drawing on an analytical framework constructed with the German concept of Bildung and the Confucian perspective on knowledge, this paper contends that a twenty first century liberal arts education for universities in China and elsewhere needs to absorb meta changes and movements in society at home and around the world, while ideally rooted in a knowledge tradition respectively. Specifically, it should comprise three essential pillars: humanism education, cognitive education, and global education. (shrink)

In recent decades, some Western philosophers have stressed the problem of the development of scientific theory within the "history of science," with special emphasis on the study of the philosophy of science as it appears in the history of modern science. In so doing they have studied the natural sciences as the process of the historical development of human knowledge of the natural universe and its lawfulness, and thus have sometimes termed such studies "theoretical dynamics." Among these, there have been (...) several different schools of thought, the best known and most influential of which include: Popper's "falsificationism," Lakatos' "methodology of research programme," and Kuhn's theory of scientific revolution.

The detection of moving targets is to detect the change area in a sequence of images and extract the moving targets from the background image. It is the basis. Whether the moving targets can be correctly detected and segmented has a huge impact on the subsequent work. Aiming at the problem of high failure rate in the detection of sports targets under complex backgrounds, this paper proposes a research on the design of an intelligent background differential model for training target (...) monitoring. This paper proposes a background difference method based on RGB colour separation. The colour image is separated into independent RGB three-channel images, and the corresponding channels are subjected to the background difference operation to obtain the foreground image of each channel. In order to retain the difference of each channel, the information of the foreground images of the three channels is fused to obtain a complete foreground image. The feature of the edge detection is not affected by light; the foreground image is corrected. From the experimental results, the ordinary background difference method uses grey value processing, and some parts of the target with different colours but similar grey levels to the background cannot be extracted. However, the method in this paper can better solve the defect of misdetection. At the same time, compared with traditional methods, it also has a higher detection efficiency. (shrink)

Since the outbreak of the COVID-19 pandemic, the physical and mental health of older adults has been threatened. Promoting physical and mental health through physical activity has therefore become a strategy for healthy aging. In order to better understand the impact of the participation of older adults in physical activity, this paper selects different types of physical activity, and examines the relationship between them and subjective well-being through the analysis of the mediation effect of outdoor exercise environment and the regulating (...) effect of exercise form. In this cross-sectional study, a questionnaire survey was conducted in mainland China. The main data come from 903 older adults in five urban areas in Chengdu, Sichuan Province. The surveys were carried out using the Physical Activity Rating Scale, Newfoundland Subjective Well-Being Scale, Exercise Environment Scale, and Exercise Form Scale. SPSS was used for statistical analysis, linear regression analysis was adopted for processing data, and AMOS was used to establish a mediation model. The mediating variable is the outdoor exercise environment, and the moderating variable is exercise form; gender, age, education level, and monthly income were used as control variables. The study results showed that different physical activities were significantly, positively correlated with the subjective well-being of older adults ; among the activities, tai chi had the strongest effect on the subjective well-being of older adults. Outdoor exercise environment played a mediating role between different physical activity types and subjective well-being of older adults [tai chi: β = 0.030, 95% CI ; health qigong: β = 0.018, 95% CI ; walking and jogging: β = 0.034, 95% CI ]. Exercise form moderated the subjective well-being of older adults in different physical activities. The results of this study demonstrate that the outdoor exercise environment plays a mediating role between different physical activities and the subjective well-being of older adults, and the form of exercise can also moderate the impact of different physical activities on the subjective well-being of older adults. This study has enlightening significance for psychological intervention with older adults facing stress, anxiety and depression. (shrink)
