Construction and Application Practice of the Digital Platform for Red Education of the Young Pioneers of China

The survey found that there is a shortage of red education and extracurricular reading among Chinese primary school students, who play video games and watch cartoons more than watch red inspirational books and movies outside of class, and lack ambitious ideals and learning motivation. To improve this situation, the research group built a digital platform for red education for Chinese children and youth and conducted a one-semester after-school reading comparison experiment among 427 elementary school students in Hangzhou LX Primary School. The post-experimental measurement found that the students in the experimental group enjoyed the “read red books + watch red movies” activity for one hour a day, and their reading time and quantity of red books/films increased significantly, their time spent playing video games and watching cartoons decreased by 46% per day, and their knowledge of Chinese revolutionary history and socialist core values, patriotic consciousness, ideal beliefs, and enthusiasm for learning also improved. Their knowledge of Chinese revolutionary history and core socialist values, patriotic consciousness, ideal beliefs, and enthusiasm for learning have also been greatly improved, and their total scores in the final exams of four courses, namely Chinese, mathematics, moral character, and English, have increased by 12% compared with those before the experiment. In contrast, in the control group, which did not carry out the reading activity and maintained the original learning and living condition, the above post-test indicators did not change significantly from the pre-test. Therefore, the experiment shows that this digital reading model has a positive effect on the cultivation of qualified communist successors, and provides experience and reference for the cultivation and education of Chinese elementary school students

Quantum phase transitional patterns in the SD-pair shell model

Patterns of shape-phase transition in the proton-neutron coupled systems are studied within the $SD$-pair shell model. The results show that some transitional patterns in the $SD$-pair shell model are similar to the $U(5)-SU(3)$, $U(5)-SO(6)$ transitions with signatures of the critical point symmetry of the interacting boson model.Comment: 13 pages, 7 figure

Online Retailer’s Return Policy and Prefactual Thinking: A Cross-Cultural Study of U.S. and Chinese E-Commerce Markets

This study examines how online fashion retailers’ return policies differ based on country-of-business. In particular, we examine whether online companies for American consumers are inclined to be more lenient and address American consumer needs to avoid uncertainty and influence prefactual thinking compared to return policies for Chinese consumers

An Application Study on AI Educational Robots in Spoken English Exercises of Chinese Primary Schools

China’s primary schools offer limited English courses, and the society lacks the environment for naturally acquiring English in everyday life. Students typically have weak spoken English abilities and inadequate application of English. With the aim of addressing this issue, 79 fifth-graders from China’s Hangzhou L elementary school participated in a one-semester AI-assisted English-speaking practice experiment. The control class practiced spoken English by reading English texts aloud, whereas the experimental class practiced for 30 minutes a day using the “AI educational robots + graded picture books + role play” approach. According to the results of the experiment’s post-test, Chinese primary school students regarded the experimental class’s acquisition mode to be highly appealing, this approach was well accepted by both students and parents and brought enthusiasm and good effect of spoken English exercise. The experimental class’s average daily reading time for English role-play reading grew by about 30 minutes, the amount of reading increased by five times, the amount of time spent watching cartoons and playing video games fell by nearly 28 minutes, and the spoken English score climbed by 37 points, representing an increase of 82% when compared to the control class; Additionally, the standard level of pronunciation and intonation has increased by two grades, from “poor” to “good,” and the English final exam scores have increased by roughly 8%. However, there has not been a considerable change in the aforementioned control class indicators. This AI-assisted second language practice technique is affordable, efficient, and helpful and has good implications for second language acquisition in other countries

Chlorophenyl-benzoxime inhibits pancreatic cancer cell proliferation, invasion and migration by down-regulating the expressions of interleukin-8 and cyclooxygenase-2

Purpose: To investigate the effects of chlorophenyl-benzoxime (CPBZX) on pancreatic cancer (PC) cell proliferation, invasion and migration, and the underlying mechanism of action. Methods: Pancreatic carcinoma cell lines (HuP-T4, HuP-T3 and BxPC-3) were cultured in Dulbecco's Modified Eagle medium (DMEM) containing 10 % fetal bovine serum (FBS), penicillin (100 U/mL) and streptomycin (10 μg/mL) at 37 ˚C in a humidified atmosphere containing 5 % CO2 and 95 % air. Cell proliferation was assessed using MTT assay. Real-time quantitative polymerase chain reaction (qRTPCR) and Western blotting were employed for the determination of changes in the levels of expression of carcinoembryonic antigen (CEA), interleukin-8 (IL-8) and cyclooxygenase-2 (COX 2). Cell invasion and migration were determined using Transwell and wound healing assays, respectively. Results: The results of MTT assay showed that CPBZX significantly and dose-dependently inhibited the proliferation of PC cells (p < 0.05). Incubation of HuP-T4 cells with CPBZX significantly and dosedependently reduced the invasive ability of the cells (p < 0.05). The migratory ability of HuP-T4 cells was also significantly and dose-dependently inhibited by CPBZX (p < 0.05). The results of Western blotting and qRT PCR showed that CPBZX treatment significantly and dose-dependently upregulated CEA mRNA expression (p < 0.05). On the other hand, the expressions of IL-8 and COX-2 were significantly and dose-dependently down-regulated by CPBZX. Treatment of pancreatic tumor mice with CPBZX significantly decreased tumor growth and metastasis of tumor cells to the pulmonary tissues, liver and lymph nodes (p < 0.05). Conclusion: The results of this study suggest that CPBZX inhibits the development and metastasis of PC via the down-regulation of IL-8 and COX 2 expressions, and therefore may find application in pancreatic cancer therapy

FastGroupII: A web-based bioinformatics platform for analyses of large 16S rDNA libraries

BACKGROUND: High-throughput sequencing makes it possible to rapidly obtain thousands of 16S rDNA sequences from environmental samples. Bioinformatic tools for the analyses of large 16S rDNA sequence databases are needed to comprehensively describe and compare these datasets. RESULTS: FastGroupII is a web-based bioinformatics platform to dereplicate large 16S rDNA libraries. FastGroupII provides users with the option of four different dereplication methods, performs rarefaction analysis, and automatically calculates the Shannon-Wiener Index and Chao1. FastGroupII was tested on a set of 16S rDNA sequences from coral-associated Bacteria. The different grouping algorithms produced similar, but not identical, results. This suggests that 16S rDNA datasets need to be analyzed in multiple ways when being used for community ecology studies. CONCLUSION: FastGroupII is an effective bioinformatics tool for the trimming and dereplication of 16S rDNA sequences. Several standard diversity indices are calculated, and the raw sequences are prepared for downstream analyses

The research on the relationship between the self-concept and the personality traits

The Piers-Harris Children's Self-Concept Scale and the Eysenck Personality Questionnaire were tested with 36 adolescent short-track skaters. This paper discussed the overall situation of self-concept of adolescent athletes in short track speed skating team and the relationship between them. The results showed that the self-concept score of athletes was obviously lower than that of the Chinese norm（p＜0.01）. The six factors of adolescent athletes' self-concept were positively correlated with extroversion-introversion（r=0.114~0.560, p＜0.05）, but they are negatively correlated with neuroticism and psychoticism（r=0.142~0.637, p＜0.05）. The interpretation of physical appearance and attributes, anxiety, behavior on the extroversion-introversion, neuroticism and psychoticism were 28.4%, 22.2% and 39.5% respectively. The interpretation of extroversion-introversion factors and neuroticism to self-concept were 26.9% and 42.5% respectively. The conclusion showed that self-concept and personality were mutually influenced and restrained in the process of development. What's more，physical appearance and attributes, anxiety and behaviors were the dominant factors that influenced the extroversion-introversion, neuroticism and psychoticism scores respectively. extroversion-introversion and the psychoticism were the most important personality features that affected the development level of self-concept.La Piers-Harris Children's Self-Concept Scale y el Eysenck Personality Questionnaire fueron probados con 36 adolescentes patinadores de pista corta. Este documento examina la situación general de autoconcepto de los atletas adolescentes en el equipo de patinaje de velocidad en pista corta y la relación entre ellos. Los resultados mostraron que la puntuación de autoconcepto de los atletas fue obviamente inferior a la de la media china (p ＜ 0.01).Los seis factores del autoconcepto de los atletas adolescentes fueron positivamente correlacionados con la extroversión-introversión (r = 0.114 ~ 0.560, p ＜ 0.05), pero están negativamente correlacionados con el neuroticismo y psicoticismo (r = 0.142 ~ 0.637, p ＜ 0.05).La interpretación de la apariencia física y los atributos, la ansiedad o el comportamiento en la extroversión-introversión, neuroticismo y psicoticismo fueron 28.4%, el 22.2% y el 39.5%, respectivamente. La interpretación de los factores de extroversión-introversión y el neuroticismo del autoconcepto fueron 26.9% y el 42.5%, respectivamente. La conclusión muestra que el autoconcepto y la personalidad son mutuamente influenciados y contenidos en el proceso de desarrollo. Además, la apariencia física y sus atributos, la ansiedad y el comportamiento fueron los factores dominantes que influyeron en las puntuaciones de extroversión-introversión, neuroticismo y psicoticismo respectivamente. La extroversión-introversión y el psicoticismo fueron las características de personalidad más importantes que afectan al nivel de desarrollo del autoconcepto
