Decision Making Under Cumulative Prospect Theory: An Alternating Direction Method of Multipliers

This paper proposes a novel numerical method for solving the problem of decision making under cumulative prospect theory (CPT), where the goal is to maximize utility subject to practical constraints, assuming only finite realizations of the associated distribution are available. Existing methods for CPT optimization rely on particular assumptions that may not hold in practice. To overcome this limitation, we present the first numerical method with a theoretical guarantee for solving CPT optimization using an alternating direction method of multipliers (ADMM). One of its subproblems involves optimization with the CPT utility subject to a chain constraint, which presents a significant challenge. To address this, we develop two methods for solving this subproblem. The first method uses dynamic programming, whereas the second method is a modified version of the pooling-adjacent-violators algorithm that incorporates the CPT utility function. Moreover, we prove the theoretical convergence of our proposed ADMM method and the two subproblem-solving methods. Finally, we conduct numerical experiments to validate our proposed approach and demonstrate how CPT’s parameters influence investor behavior, using real-world data.

Distribution of the mysterious Chevron Crickets Melanabropsis Wang & Liu, 2020, with a remarkable new species from Hainan, China (Orthoptera: Anostostomatidae: Anabropsini)

Melanabropsis is a rare genus of Chevron Crickets from East Asia. In this study, Melanabropsis nightfury sp. nov. is described from Hainan Island in China. The new species is the first macropterous species belonging to the genus Melanabropsis, distinctly different from other species of the genus, which are all micropterous. Based on the data of the new species and records on iNaturalist, a suitability distribution map of the genus is generated using the Maxent model. The results indicate that this genus is primarily distributed in islands and mountains with small temperature differences and high precipitation. Taiwan Island in China shows high potential for distribution. Type specimens are deposited in the Museum of Biology, East China Normal University.

Status, influencing factors and paths on professional identity of special education teachers

ABSTRACT The aim of the present study was to explore the status, influencing factors and paths on professional identity of special education teachers. The statistical population of the study included 438 special education teachers in Guangdong Province, China. The age of the participants ranged from 22 to 57 years old (M = 32.16, SD = 1.85 years). Of the 438 teachers, 346 were females, 92 were males. The Occupational Stress Questionnaire (He, J. H. 2013. A Study on the Occupational Stress and Work Engagement of Special Education Teacher. Hangzhou: Hangzhou Preschool Normal College of Zhejiang Normal University), School Support Questionnaire (Zhang, Y. 2018. Study on Professional Identity and School Support of Special Education Teachers in Guizhou. Chengdu: Sichuan Normal University), and Professional Identity Questionnaire (Tang, J. R. 2012. Study on Professional Identity of Special School Teachers. Shanghai: East China Normal University) were used. The independent sample t-test, one way ANOVA, correlation analysis, and multiple stepwise regression were used for the data analysis. The results show that: (1) the professional identity of special education teachers is relatively high in the overall and dimensions. (2) There are significant differences in the professional identity in terms of leadership, marriage, education level, teaching years and professional titles. (3) Both occupational stress and school support can significantly predict the professional identity of special education teachers.

Narrative inquiry in China

Narrative inquiry has been widely used in different disciplines around the world. In this article, we focus on narrative inquiry in China where we start by retelling our first close contact with narrative researchers in China in 2007 when Professor Gang Ding at East China Normal University invited leading Chinese researchers to a three-day narrative inquiry workshop co-planned with us (Connelly and Xu). Second, we review narrative studies published in Chinese to demonstrate how widely narrative inquiry has been adopted in educational studies in the country in the past two decades by Chinese university researchers, graduate students, and schoolteachers. Next, our review of English literature of narrative studies related to education in China has two important components: English literature on narrative inquiry contextualized in China and narrative inquiry for reciprocal learning in teacher education and school education between Canada and China. Both reveal how narrative inquiry has contributed to international cross-cultural educational studies related to Chinese contexts. Finally, in the “Discussion” section, we provide our interpretation of some current dialogs on narrative inquiry among Chinese educational researchers; for example, the differences between yanjiu 研究 (research) and tanjiu 探究 (inquiry). Some heated discussions surrounding narrative inquiry in China are also highlighted, including: (1) cultural complexities in narrative inquiry, (2) theoretical frameworks in narrative inquiry, (3) re-storying and fictionalization processes in narrative inquiry, and (4) ethical considerations in narrative inquiry. To conclude, with cases selected and elaborated from the Canada-China partnership, we demonstrate how narrative inquiry has enabled us to develop “reciprocal learning” as both a conceptual framework and a methodological approach to building a multidimensional bridge for reciprocal learning in education between the West and East. This Reciprocal Learning approach reflects our global comparative studies view that the path to global cross-cultural harmony and understanding lies with collaborative action plans among people of different cultures. Writing this article on narrative inquiry in China enabled us to reflect on and learn from narrative inquirers and researchers in China while sharing what we have done in our own narrative inquiry.

Personalization of clopidogrel therapy based on genetic polymorphism analysis: clinical implications.

This study aimed to evaluate the impact of gene polymorphisms on clopidogrel metabolism and to use this analysis to inform treatment strategy for a population in southern Anhui of China. The research was conducted from 2019 to 2022, aincluding 430 patients from the Wuhu Hospital, affiliated with East China Normal University who were candidates for clopidogrel therapy. Genes influencing clopidogrel's absorption and metabolism were analyzed to guide treatment. Patient data were collected, and genotype and metabolic type distributions were compared. Patients needing medication adjustments were followed up and divided into two groups based on whether they received adjustments or not, and the re-admission rates for antiplatelet therapy within 12 months were compared. The 430 samples showed the expected genotypes and gene distribution, with no significant correlation to age or sex. The CYP2C19 metabolic phenotype frequency was moderate at 57.44%, fast at 25.12%, slow at 15.58%, and ultra-fast at 1.86%. The ABCB1-3435C>T genotype distribution was wild type in 38.14%, heterozygous in 42.33%, and mutant homozygous in 19.53%, with the TT group being significantly younger. The PON1-576G>A genotype showed no significant baseline differences. Of the 279 patients needing medication advice, 39.07% received it. The adjusted group had a significantly lower re-admission rate within one year. The distribution of gene polymorphisms related to clopidogrel metabolism varied within the study population, indicating a potential for personalized medication approaches. The study provides insight into the clinical application of genetic testing for clopidogrel therapy.

The Study of the History of Russian Emigration by Modern Chinese Scholars (According to the Scientific Site CNKI — 中国知网)

In China and Russia in recent years, the history of Russian emigration has attracted increased interest from many scholars. The purpose of the article is to identify and systematize publications about the fate of Russian emigrants in China, posted on the site “Zhiwang” (中国知 网, www.cnki.net). The analysis of information on this topic made it possible to identify the degree of interest of Chinese scientists in the study of intellectual and cultural heritage. The authors draw attention to the scientific and educational activities of educational organizations (Harbin Normal University, Heilongjiang University, Qiqihar University, Heihe University, East China Normal University, etc.) and scientific foundations (State Social Science Foundation of China, Philosophy and Social Science Foundation of Heilongjiang Province, etc.), which provided financial support and documentation support for the ongoing research. The authors of the article used their thematic focus as the main criterion for systematizing the publications of the Chinese site “Zhiwang”. The article focuses on quantitative indicators: the number of publications of Chinese scientists on the history of Russian emigration, the publication activity of the most famous Chinese Scientists-Slavists who described the fate of Russians who ended up in China. The applied value of the description by Chinese scientists of the educational and research, professional and entrepreneurial activities of Russian emigrants is noted. The opinion of Chinese scientists is emphasized that the culture (literature, painting, music) of Russian emigrants who settled in the cities of Northern China, adapted in the cultural space of the local population, left a significant mark in the history of China. The authors come to the conclusion that the cultural and historical heritage of Russian emigrants can currently be used not only to preserve national and spiritual values, but also to strengthen cultural interaction between China and Russia.

A135: Challenges and Strategies of Physical Fitness Course in Primary and Middle Schools

Purpose: Developing students’ overall competencies and physical health is an important goal of physical education and health curriculum (PEHC). PEHC Standards for Compulsory Education (2022) and PEHC Standards for Senior High Schools (2017) both designate Physical Fitness as a required course to achieve this goal. To date, it’s not clear about how the course has been implemented and its effectiveness. Therefore, this study was to identify problems associated with teaching Physical Fitness courses in primary and middle schools in China and to propose strategies for an improved implementation. Methods: First, the literature from CNKI, East China Normal University Library was extensively collected and analyzed. Second, to learn about the current status of Physical Fitness teaching in the primary and middle schools, experts in physical education and Physical Fitness teaching were interviewed. Results: The problems of Physical Fitness teaching in some primary and middle schools are as follows: (1) the course only focuses on the development of students’ motor abilities, ignoring healthy behavior and sportsmanship; (2) the course only contains skill explanation and demonstration, failing to teach principles, knowledge and methods of physical fitness development; (3) some Physical Fitness courses lack scientific and systematic implementation; (4) a number of physical education teachers lack the knowledges and abilities to teach the course; and (5) limited instructional resources, including lack of textbooks, for teachers to prepare lessons. Conclusion: To solve the problems identified above, we propose the following strategies: (1) The Physical Fitness course should focus on developing students’ overall competencies; (2) teachers include explanations of general principles, knowledge and methods for physical fitness development; (3) develop scientific and systematic Physical Fitness course content and methods; (4) increase physical education teachers’ knowledge and abilities of teaching Physical Fitness course; and (5) write textbooks suitable for the Physical Fitness course in the primary and middle schools.

An empirical study on the effect of academic engagement on academic achievement of engineering students in colleges and universities

Abstract Based on the linear regression algorithm, this paper uses the basic linear regression algorithm and the kernel linear regression algorithm to construct the relationship model between academic input and academic achievement based on linear regression and to determine the independent variables, dependent variables and control variables in the model. The engineering students of East China Normal University are selected as the research object, the research instrument is determined, the research index is determined according to the survey, and the research hypothesis is proposed, and then the research and analysis design of the impact of academic input on academic achievement is completed. Using reliability and validity to test the validity of the questionnaire, the initial data of the study can be obtained by distributing the questionnaire, and correlation analysis and regression analysis are used to carry out an empirical study of academic input and academic achievement based on linear regression. The results show that the correlation coefficient between academic input and academic achievement of master’s degree students is R=0.892 and R2=0.792, indicating that the predictive variance of academic input on academic achievement is 89.2%. The effects of the dimensions under the academic input on the social adjustment dimension under the academic achievement were, in descending order, as follows: active cooperation > teacher-student interaction > educational enrichment > academic challenge > campus support. This study comprehensively analyzes the impact of academic engagement on academic achievement, and colleges and universities should change the test of students’ ability to memorize knowledge and skills to the test of students’ ability to analyze and solve problems by applying what they have learned.

Exploring the path of high-quality development of teacher education and teaching based on collaborative filtering algorithm

Abstract In this paper, firstly, a collaborative filtering algorithm based on users is used to mine the past behaviors of the target users. Items are glanced and composed to gain insight into the user’s preferred items and to mine preference information, followed by searching for users with similar preferences to the user in the system and calculating the similarity between users and users using cosine similarity and pearson similarity, and predicting the target user’s rating of an element based on the rating value of an item given by a nearby user. Then the personalized teaching system is designed by the actual situation of the online teacher teaching courses on the platform and the course demands of the platform students, and the path of high-quality improvement of teacher training and teaching is studied, mainly focusing on three aspects: clear value orientation, good personalized system teaching planning, and implementation of multiple evaluations. When analyzing the student-teacher ratio of teacher education institutions, the student-teacher ratio of Central China Normal University has the largest value, 24.79%, while the values of East China Normal University and Nanjing Normal University are relatively small, 15.97% and 15.39%, respectively. Either based on theory or based on practice, any institution of higher education with an excessive student-teacher ratio. This study helps teachers grow professionally and provides a good foundation for eventual individualized student development.

Auxiliary Diagnosis of Papillary Thyroid Carcinoma Based on Spectral Phenotype.

Thyroid cancer, a common endocrine malignancy, is one of the leading death causes among endocrine tumors. The diagnosis of pathological section analysis suffers from diagnostic delay and cumbersome operating procedures. Therefore, we intend to construct the models based on spectral data that can be potentially used for rapid intraoperative papillary thyroid carcinoma (PTC) diagnosis and characterize PTC characteristics. To alleviate any concerns pathologists may have about using the model, we conducted an analysis of the used bands that can be interpreted pathologically. A spectra acquisition system was first built to acquire spectra of pathological section images from 91 patients. The obtained spectral dataset contains 217 spectra of normal thyroid tissue and 217 spectra of PTC tissue. Clinical data of the corresponding patients were collected for subsequent model interpretability analysis. The experiment has been approved by the Ethics Review Committee of the Wuhu Hospital of East China Normal University. The spectral preprocessing method was used to process the spectra, and the preprocessed signal respectively optimized by the first and secondary informative wavelengths selection was used to develop the PTC detection models. The PTC detection model using mean centering (MC) and multiple scattering correction (MSC) has optimal performance, and the reasons for the good performance were analyzed in combination with the spectral acquisition process and composition of the test slide. For model interpretable analysis, the near-ultraviolet band selected for modeling corresponds to the location of amino acid absorption peak, and this is consistent with the clinical phenomenon of significantly lower amino acid concentrations in PTC patients. Moreover, the absorption peak of hemoglobin selected for modeling is consistent with the low hemoglobin index in PTC patients. In addition, the correlation analysis was performed between the selected wavelengths and the clinical data, and the results show: the reflection intensity of selected wavelengths in normal cells has a moderate correlation with cell arrangement structure, nucleus size and free thyroxine (FT4), and has a strong correlation with triiodothyronine (T3); the reflection intensity of selected bands in PTC cells has a moderate correlation with free triiodothyronine (FT3).

Analysis of the cultivation of social responsibility of physical education students in the context of Healthy China

Background and Study Aim. 'Healthy China’ is an important symbol of China's social development and national prosperity. As practitioners and disseminators of sports and health, physical education of students should actively play their own specialties in the process of "Healthy China" construction. This study investigates the social responsibility and cultivation of college students so as to create a good atmosphere for educational groups from the four levels of society, family, school, and itself. Material and Methods. The participants were 53 students (aged 19-21 years) from the College of Physical Education and Health of East China Normal University. The "Questionnaire on the Cultivation of Social Responsibility of Students Majoring in Physical Education" was used as a search tool. A total of 60 questionnaires were distributed using the online platform in this study, and 53 valid questionnaires were recovered after sorting and screening. Among them, 32 were male students and 21 were female students. Results. Students lack enthusiasm and initiative in paying attention to national policies, learning health knowledge and technology, and participating in health education. There is also a lack of self-control and perseverance in physical exercise and healthy eating. Insufficient sleep and poor psychological state lead to low participation in social activities; College students have a low awareness of promoting sports spirit. Conclusions. The findings of this study shed light on the crucial need to cultivate social responsibility among college students majoring in sports at multiple levels: society, family, school, and individual. To effectively promote "Healthy China" and maximize the potential impact of physical education students, concerted efforts must be made to address the identified shortcomings and foster a holistic approach to social responsibility.

Association between physical activity, sedentary time, and physical fitness of female college students in China

BackgroundPrior research has highlighted the importance of Physical Activity (PA), Sedentary Time (ST), and Physical Fitness (PF) for health. However, there is limited research on the association between PA, ST, and PF in the context of female college students, particularly in Eastern cultures. Therefore, the purpose of this study was to investigate the association between PA, ST, and PF among Eastern female college students to inform policy and practice.MethodsThe study was conducted from February to May 2022 at East China Normal University, Shanghai, China. A total of 512 Chinese female college students participated in this study through snowball sampling. Participants’ PA and ST were investigated using the International PA Questionnaire, and PF was measured using the Chinese National Student Physical Fitness Test. Independent samples t-test and binary logistic regression were used to compare the differences in PF between Active Participants (AP) and Inactive Participants (IP), as well as between Low Sedentary Participants (LSP) and High Sedentary Participants (HSP). Multinomial logistic regression was used to compare the differences in PF between Active and Low Sedentary Participants (ALSP), Active and High Sedentary Participants (AHSP), Inactive and Low Sedentary Participants (ILSP), and Inactive and High Sedentary Participants (IHSP). Data analysis was performed using Statistical Package for the Social Sciences version 28. The level of significance was set at 0.05.ResultsAP showed significantly higher cardiorespiratory fitness (p < 0.05) and overall fitness (p < 0.01) than IP. Compared to IP, AP was less likely to be classified as unfit in terms of cardiorespiratory fitness [Odds Ratio (OR), 0.57; 95% Confidence Interval (CI), 0.38–0.85; p < 0.05]. Compared to IHSP, ALSP (OR, 0.44; 95% CI 0.25–0.76; p < 0.01) and AHSP (OR, 0.54; 95% CI 0.32–0.93; p < 0.05) were less likely to be classified as unfit in terms of cardiorespiratory fitness. Furthermore, compared to IHSP, AHSP (OR, 1.66; 95% CI 1.02–2.70; p < 0.05) and ILSP (OR, 2.09; 95% CI 1.16–3.77; p < 0.05) were more likely to be classified as unfit in terms of their flexibility.ConclusionThere was a positive association between PA, cardiorespiratory fitness, and overall fitness. There was also an association between cardiorespiratory fitness, flexibility, and the combination of PA and ST. These findings suggest that both PA and ST can influence different PF items. Therefore, we recommend that public health policy and practice for college female students should consider PF items when selecting different PA and ST intervention strategies.

A new species of the genus Larnaca from Guangxi, China (Orthoptera: Gryllacrididae: Gryllacridinae).

Larnaca (Larnaca) lieyongzhou sp. nov. is described from Guangxi, China. This species is characterized by the unique shape of the lobes on females 7th abdominal tergite. Types of the new species in this paper are deposited in Museum of Biology, East China Normal University.

A new species of whip spider, Sarax sinensis sp. nov., from Fujian, China (Arachnida: Amblypygi: Charinidae).

To date, only two whip spider species have been recorded in China. We describe a new species, Sarax sinensis sp. nov., from Fujian, China. This species is morphologically similar to S. ioanniticus (Kritscher, 1959), S. israelensis (Miranda et al., 2016), and S. seychellarum (Kraepelin, 1898), but can be distinguished by the combination of the following characters: 35 segments in leg I tarsus, eight teeth on cheliceral claw, and four dorsal and ventral spines respectively on pedipalp femur. To examine the evolutionary history of S. sinensis sp. nov., we sequenced 12S, 16S, and COI gene regions of our specimens and inferred its phylogenetic position. The inferred phylogenetic trees placed the new species within Sarax, with its closest relative being distributed across the western Asia. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).
