Defiant Retreat： The Relocation of Middle Schools to China＇s Interior, 1937-1945

引用

Frontiers of History in China 2013年第4期8卷 558-584页

作者： jennifer liu Department of History Central Michigan University Mount Pleasant MI 48859 USA

This study focuses on the migration of middle school students to the interior of China after the Japanese invaded in 1937. It argues that the Guomindang （GMD） central government was generally successful in handling the 500,000 displaced students, making substantial efforts to monitor, register, educate, and provide training for them, as well as establishing government-run ＂national middle schools＂ during the war. Meanwhile, the GMD also exerted a strong influence on course curriculum, instructing educators how to implement the Three People＇s Principles and other party doctrines in classrooms. These processes expanded the state＇s hand in secondary education and allowed the GMD to include refugee students and schools in its wartime narrative of progress, praising the students＇ patriotic participation in defying the Japanese occupiers and their contribution to ＂national reconstruction＂（jianguo）. However, there were still many challenges. Refugee students, teachers, and principals forcibly converted Buddhist temples into schools and clashed with local monks, farmers, villagers, and even the GMD military. With schools merging and moving inland, relocation also provided opportunities for unscrupulous administrators and teachers to exploit the situation for themselves, as government reports reveal many cases of corruption in the wartime schools.

Archean-Paleoproterozoic Lithospheric Mantle at the Northern Margin of the North China Craton Represented by Tectonically Exhumed Peridotites

引用

Acta Geologica Sinica(English Edition) 2017年第6期91卷 2041-2057页

作者： TIAN Wei WANG Shuangyue liu Fenglin CHU Zhuyin WANG Bin CHEN Mimi jennifer PRICHARD Key Laboratory of Orogenic Belts and Crustal Evolution MOESchool of Earth and Space SciencesPeking University State Key Laboratory of Lithospheric Evolution Institute of Geology and GeophysicsChinese Academy of Sciences Research School of Earth and Space Sciences the Australian National University

Tectonically emplaced peridotites from North Hebei Province, North China Craton, have retained an original harzburgite mineral assemblage of olivine （54%-58%）＋ orthopyroxene （40%-46%）＋minor clinopyroxene （〈1%）＋spinel. Samples with honinite-like chemical compositions also coexist with these peridotites. The spinels within the peridotites have high-A1 end-members with A1203 content of 30 wt%-50 wt%, typical of mantle spinels. When compared with experimentally determined melt extraction trajectories, the harzburgites display a high degree of melting and enrichment of SiO2, which is typical of cratonic mantle peridotites. The peridotites display variably enriched light rare earth elements （REEs）, relatively depleted middle REEs and weakly fractionated heavy REEs, which suggest a melt extraction of over 25% in the spinel stability field. The occurrence of are- and SSZ-type chromian spinels in the peridotites suggests that melt extraction and metasomatism occurred mostly in a subduction-related setting. This is also supported by the geochemical data of the coexisting boninite-like samples. The peridotites have lS7Os/lSSOs ratios ranging from 0.113-0.122, which is typical of cratonic iithospheric mantle. These lSTOs/ISSOs ratios yield model melt extraction ages （TRD） ranging from 981 Ma to 2054 Ma, which may represent the minimum estimation of the melt extraction age. The Ai203- lSTOs/lSSOs-proxy isochron ages of 2.4 Ga-2.7 Ga suggest a mantle melt depletion age between the Late Achaean and Early Paleoproterozoic. Both the peridotites and boninite-like rocks are therefore interpreted as tectonically exhumed continental lithospheric mantle of the North China Craton, which has experienced mantle melt depletion and subduction-related mantle metasomatism during the Neoarchean- Paleoproterozoic.

Application of Drone in Solving Last Mile Parcel Delivery

Journal of Systems Science and Information 2018年第4期9卷 302-319页

作者： Jiashi liu Zhongliang GUAN jennifer SHANG Xiang XIE School of Economics and Management Beijing Jiaotong University Joseph M.Katz Graduate School of Business University of Pittsburgh

The article is about solving the last mile delivery problem in rural town or village. We want to test the drone’s potential in parcel delivery. The objectives are 1) to introduce the cluster and truck-drone in tandem delivery method, 2) to compare the new method with the traditional TSP method in aspect of truck running distance, energy using and time occupation. The parcel delivery demand is sparse, so it is not dense enough for a truck to carry on delivery. We try to identify the best route for the drone to deliver the goods. We use k-mean method to carry on clustering, then we use enumeration method to fulfill the centroids delivery, which comes from the depot. We design a model and calculate the energy, time and distance saving between drone using method(DTSP) and traditional TSP method. The drone attended delivery saves truck delivery distance, energy consumption and *** truck running distance of DTSP method saves 91.87%, the truck running distance is shortened from 189.69 km to 15.4252 km. The DTSP method saves 90.45% of energy. The DTSP method brings a29.75% cutoff in time aspect when there are two drone in running. The research introduces the cluster and TSP combination method, which is a good way to carry on last mile delivery. The result shows a bright future for drone to attend parcel delivery. The e-commerce corporation can apply this method in practice.

High-temperature magnetic properties of anisotropic Mn Bi/Nd Fe B hybrid bonded magnets

引用

Rare Metals 2016年第6期35卷 471-474页

作者： Dong-Tao Zhang Peng-Fan Wang Ming Yue Wei-Qiang liu Jiu-Xing Zhang jennifer Anand Sundararajan You Qiang College of Materials Science and Engineering Beijing University of Technology Physics Department University of Idaho

Anisotropic MnBi/NdFeB （MnBi contents of 0 wt%, 20 wt%, 40 wt%, 60 wt%, 80 wt%, and 100 wt%） hybrid bonded magnets were prepared by molding compression using MnBi powders and commercial hydro-genation disproportionation desorption and recombination （HDDR） NdFeB powders. Magnetic measurements at room temperature show that with MnBi content increasing, the magnetic properties of the MnBi/NdFeB hybrid bonded magnets all decrease gradually, while the density of the hybrid magnets improves almost linearly. In a temperature range of 293-398 K, the coercivity temperature coefficient of the hybrid magnets improves gradually from -0.59 %.K^-1 for the pure NdFeB bonded magnet to -0.32 %.K^-1 for the hybrid bonded magnet with 80 wt% MnBi, and the pure MnBi bonded magnet exhibits a positive coercivity temperature coefficient of 0.61%-K^-1.
