This paper presents an analytical approach for estimating frictional resistance to pipe movement at soil and external pipe surface of buried coated pressurized steel pipes relative to the internal thrust *** proposed analytical method was developed based on 36 experiments,which involved three coating types(cement mortar(CM),polyurethane type-I(PT-I),prefabricated plastic tape(PPT))on pipes’surfaces,three different soils(pea-gravel(PG),sand(S),silty-clay(SC)),and four simulated over burden depths above the pipe’s *** showed frictional resistance decreased with increasing over burden depth above the pipe’s *** degree of frictional resistance at the pipe-soil interface was found to be in the order of PG>SC>S for all coating variations and overburden *** coated pipe buried in all three types of soil produced significantly higher frictional resistance as compared to other coating *** on experimental data,the developed analytical introduced a dimensionless factor“Z”,which included effects of types of coatings,soil,and overburden depths for simplified rapid *** showed that the method provided a better prediction of frictional resistance forces,in comparison to previous analytical methods,which were barely close in predicting friction resistance for different coating variations,soil types,and overburden *** resistance force values reported herein could be considered conservative.

What Knowledge is of Most Worth?Considering the Neo-Confucians in the Contemporary Debate Between Moral and Intellectual Learning

引用

ECNU Review of Education 2024年第1期7卷 155-163页

作者： john Patrick Shekitka Manhattanville College

●The perennial debate regarding the relative usefulness of various forms of knowledge,especially between the theoretical and practical and the intellectual and moral,lies at the heart of education in both past and present times in both the West and China(de Bary,1988,2004,2005,2015).●Neo-Confucians remain relevant in the 21st century and can help us to understand and elucidate contemporary debates in education-specifically,to answer the question Spencer asked nearly a century and a half ago:"What knowledge is of most worth?".●Mencius,Zhu Xi,Wang Yangming,Xu Ai,and Kang Youwei advocated for a type of learning that would strongly resonate with john Dewey(1938)and Paulo Freire(1970,1978).Foundational philosophies of education,particularly in the United States,have drawn heavily on 20th century European-American thinkers;this article attempts to correct this myopia and broaden perspectives.
