Juvenile Delinquency in China: Causes and Prevention

Juvenile delinquency is one of the most complex social issues confronting both developing and developed nations in today’s rapidly changing world. In China, adolescent criminality is likewise increasing at an alarming rate. In this study, we examined the status quo of juvenile delinquency in China, elucidated the reasons for adolescent crime from the perspectives of the individual, family, school, and society, and proposed preventive methods to provide insight into the reduction of juvenile delinquency in China

Ethical Risks in Integrating Artificial Intelligence into Education and Potential Countermeasures

A developing trend is the integration of artificial intelligence (AI) into education. As a result of the widespread adoption of educational AI, the ethical risks it poses have raised growing public concern. The use of educational AI poses three key ethical risks: the risk of educational data security; the risk of deconstructing the teacher-student role structure and educational inequality; and the risk of alienation from educational goals. We herein advocate as countermeasures the redefinition of teachers’ fundamental duties, the instruction of students in the sensible use of AI, and the promotion of effective regulation of AI’s deployment in education

Risks in Online College Student Lending in China and Coordinated Regulation

Since its introduction to China in 2007, online lending has witnessed a boom, aided by the impetus of internet development. Due to the peculiarities of the borrowers, online college student loans facilitated by peer-to-peer lending platforms have sparked widespread public concern. Many issues plague online lending operations for college students, including unclear duties of the platform, immature approval and exit regulations, interest rates, and fee structures; knowledge asymmetry in the transaction; and false publicity of the platform for profiteering purposes. As a result, internet lending risks are increasing, including credit risk, usury risk, and information leakage risk. The objective of this research was to provide implications for risk avoidance and action by exploring the causes of these risks and describing the current governance of online student lending

Estimation of swell height using spaceborne GNSS-R data from eight CYGNSS satellites

Global Navigation Satellite System (GNSS)-Reflectometry (GNSS-R) technology has opened a new window for ocean remote sensing because of its unique advantages, including short revisit period, low observation cost, and high spatial-temporal resolution. In this article, we investigated the potential of estimating swell height from delay-Doppler maps (DDMs) data generated by spaceborne GNSS-R. Three observables extracted from the DDM are introduced for swell height estimation, including delay-Doppler map average (DDMA), the leading edge slope (LES) of the integrated delay waveform (IDW), and trailing edge slope (TES) of the IDW. We propose one modeling scheme for each observable. To improve the swell height estimation performance of a single observable-based method, we present a data fusion approach based on particle swarm optimization (PSO). Furthermore, a simulated annealing aided PSO (SA-PSO) algorithm is proposed to handle the problem of local optimal solution for the PSO algorithm. Extensive testing has been performed and the results show that the swell height estimated by the proposed methods is highly consistent with reference data, i.e., the ERA5 swell height. The correlation coefficient (CC) is 0.86 and the root mean square error (RMSE) is 0.56 m. Particularly, the SA-PSO method achieved the best performance, with RMSE, CC, and mean absolute percentage error (MAPE) being 0.39 m, 0.92, and 18.98%, respectively. Compared with the DDMA, LES, TES, and PSO methods, the RMSE of the SA-PSO method is improved by 23.53%, 26.42%, 30.36%, and 7.14%, respectively.This work was supported in part by the National Natural Science Foundation of China under Grant 42174022, in part by the Future Scientists Program of China University of Mining and Technology under Grant 2020WLKXJ049, in part by the Postgraduate Research & Practice Innovation Program of Jiangsu Province under Grant KYCX20_2003, in part by the Programme of Introducing Talents of Discipline to Universities, Plan 111, Grant No. B20046, and in part by the China Scholarship Council (CSC) through a State Scholarship Fund (No. 202106420009).Peer ReviewedPostprint (published version

Review on the Compulsory Education Status of Migrant Workers’ Children in Chinese Cities

With the advancement of China’s economic and social development and urbanization, the scale of out-of-town migrant workers has been expanding. Following this, migrant worker children’s education problem has become increasingly prominent and has gradually become a focus of education research. This paper reviews recent studies on migrant worker children’s acceptance of compulsory education, and summarizes its existing education problems, aiming to provide direction and support for further promoting education equity and sustainable development of urban and rural education

OsMKKK70 Negatively Regulates Cold Tolerance at Booting Stage in Rice

Cold stress at the booting stage leads to a lower seed setting rate and seriously threatens the production of rice (Oryza sativa L.), which has become a major yield-limiting factor in higher-altitude and -latitude regions. Because cold tolerance at the booting stage (CTB) is a complex trait and is controlled by multiple loci, only a few genes have been reported so far. In this study, a function of OsMKKK70 (Mitogen Activated Protein Kinase Kinase Kinase 70) in response to CTB was characterized. OsMKKK70 expression was rapidly induced by cold stress at the booting stage. OsMKKK70 overexpression (OsMKKK70-OE) plants were more sensitive to cold stress at the booting stage with a lower seed setting and pollen fertility, but there was no significant difference between the osmkkk70 mutant and WT. Considering the effect of functional redundancy, we further tested the CTB response of osmkkk62/70 and osmkkk55/62/70, the double and triple mutants of OsMKKK70 with its closest homologs OsMKKK62 and OsMKKK55, and found that osmkkk62/70 and osmkkk55/62/70 displayed significantly increased CTB with a higher seed setting and pollen fertility, indicating that OsMKKK70 negatively regulates rice CTB. Moreover, under the low-temperature (LT) condition, the osmkkk62/70 mutant had slightly higher Gibberellin (GA) contents, increased expression of GA biosynthesis genes, and lower protein level of OsSLR1 in anthers than those in WT. By contrast, OsMKKK70-OE anther had a lower GA biosynthesis than that of WT. Together, these findings suggest that OsMKKK70 negatively regulates rice CTB by fine-tuning GA levels in anthers
