Health risk assessment of trace metal(loid)s in agricultural soils based on Monte Carlo simulation coupled with positive matrix factorization model in Chongqing, southwest China

This study aimed to investigate the pollution characteristics, source apportionment, and health risks associated with trace metal(loid)s(TMs) in the major agricultural producing areas in Chongqing, China. We analyzed the source apportionment and assessed the health risk of TMs in agricultural soils by using positive matrix factorization(PMF) model and health risk assessment(HRA) model based on Monte Carlo simulation. Meanwhile, we combined PMF and HRA models to explore the health risks of TMs in agricultural soils by different pollution sources to determine the priority control factors. Results showed that the average contents of cadmium(Cd), arsenic (As), lead(Pb), chromium(Cr), copper(Cu), nickel(Ni), and zinc(Zn) in the soil were found to be 0.26, 5.93, 27.14, 61.32, 23.81, 32.45, and 78.65 mg/kg, respectively. Spatial analysis and source apportionment analysis revealed that urban and industrial sources, agricultural sources, and natural sources accounted for 33.0%, 27.7%, and 39.3% of TM accumulation in the soil, respectively. In the HRA model based on Monte Carlo simulation, noncarcinogenic risks were deemed negligible(hazard index <1), the carcinogenic risks were at acceptable level(10^(-6)<total carcinogenic risk ≤ 10^(-4)), with higher risks observed for children compared to adults. The relationship between TMs, their sources, and health risks indicated that urban and industrial sources were primarily associated with As, contributing to 75.1% of carcinogenic risks and 55.7% of non-carcinogenic risks, making them the primary control factors. Meanwhile, agricultural sources were primarily linked to Cd and Pb, contributing to 13.1% of carcinogenic risks and 21.8% of non-carcinogenic risks, designating them as secondary control factors.

The Role of Teachers’Apperception in Herbart’s Theory for Chinese Teaching in Shenzhen Primary Schools of China

This paper deeply analyzes the practical application of Herbart’s educational concept in contemporary education and teaching,especially its guiding significance to the primary school Chinese classroom in Shenzhen area.Herbart proposed that teachers should play a key role in students’cognitive process,that is,help students better understand and master new knowledge by combining it with existing knowledge.The survey results show that although teachers have some understanding of Herbart’s educational philosophy,it is not widely used in the concrete teaching process.However,the study also shows that there is a positive relationship between Herbart’s theory and students’academic performance,indicating that it plays an important role in improving students’interest and engagement in learning.The research also reveals the differences between educational concepts and practices,as well as the uneven distribution of educational resources,and puts forward measures to alleviate these contradictions,such as strengthening teacher training,improving teaching methods,and emphasizing moral education.At the same time,the study also highlights the critical role of teachers in promoting knowledge integration,arousing learning enthusiasm,shaping students’moral character,and promoting personal and professional growth.

The role repositioning of teacher and student in the process of knowledge internalization under flipped classroom

Flipped classroom model led to the transformation of university teachers＇ teaching role. From the perspective of the sociology of knowledge, the teacher professional development is a process of transformation of the role of teachers, and role transformation and the way of actors involved in the knowledge are associated. Participating in knowledge in different ways, role types are also different. Thus, changing the way ofparticipating in knowledge is the basic way to participate in the transformation of the role. Classification of roles is not the classification ofhumans.A social may might play many roles of many types in his life andmay have the function of a variety of roles at the same time. Meanwhile, it can be transferred between characters, especially in the case of depending on the same knowledge system.As long as the ways of involvement are different,the functions and types of roles are also different. University teachers are those who play a variety of roles of knowledge and society, some being the teaching teachers of organization and dissemination of knowledge, some being scientific and teaching teachers who focus on organizing and disseminating knowledge as well as knowledge creation, and knowledge creation and heavy teacher teaching and research, while others are knowledge creation based research teachers. In the field of the sociology of knowledge, university teachers should be scientific teaching roles depending on a deep knowledge and participating in knowledge in a variety of ways. From the perspective of the sociology of knowledge, according to Eph · Znaniecki＇ s role classification, university teachers participate in knowledge in three ways： teaching, learning and researching. Teaching, learning and researching are relative but different ways of participating in knowledge. State they are relative because itshows teaching can promote learning, learning can promote researching, researching can also promote learning and teaching. The homochromous interaction of teaching, leaming and researching, knowledge is in constant state of development and generation.

从协同到求异:指向教师专业发展的U-S合作优化研究

U-S合作是教师专业发展的重要举措。审视U-S合作的历程可知,U-S合作致力于多方位促进教师专业发展,协同逐渐成为U-S合作促进教师专业发展的底层逻辑。随着合作的持续推进,这一底层逻辑在促进教师专业发展方面所潜在的矛盾也逐渐暴露出来。一方面,大学与中小学的文化差异阻碍了协同的深度发生;另一方面,为了实现大学与中小学的协同,双方不得不做出诸多的妥协,在妥协的语境下,中小学教师往往面临着主体性丧失的风险。与之相对,在求异这一核心理念的引领下,跨界学习旗帜鲜明地提出了“差异即资源”的主张,并通过互动场域的营造和互动系统的建构,为“差异即资源”提供了现实可能,也为优化U-S合作提供了新的思路。
