馬克思主義概念翻譯在中國1900-1949

本論文探討馬克思主義經由翻譯介紹到中國的歷史過程。馬克思主義作為中共立國的意識形態，已經成為一種權威的話語。但在本世紀初經由翻譯傳入的馬克思主義，並不是一套教條。在二十世紀初到二、三十年代間，多種思潮互相衝擊，馬克思主義在翻譯傳入的過程中，也是知識份子分析社會矛盾性質和思考社會變革的思想資源。對馬克思主義的翻譯與介紹，揭示了翻譯本身是在一定的文化政治的位置中的論述踐行。 本論文以幾個馬克思主義概念為例，將這些概念置放於其歷史脈絡中，考察這些概念在個別知識份子的著述中怎樣被理解，討論翻譯的過程中牽涉的各種閱讀策略，並嘗試說明它們如何構築各種身分。論文嘗試說明這些概念的互譯性是藉著種種論述與實踐建立起來的

TiO2 Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials

Graphene/TiO2 nanocrystals hybrid is successfully prepared by directly growing TiO2 nanocrystals on graphene oxide (GO) sheets. The direct growth of nanocrystals on GO sheets was achieved by a two-step method, in which TiO2 was coated on GO sheets by hydrolysis first and crystallized into anatase nanocrystals by hydrothermal treatment in second step. Slow hydrolysis reaction through the use of EtOH/H2O mixed solvents and addition of H2SO4 allows the selectively growing TiO2 on GO and suppressing free growth in solution. The method offers easy access to the GO/TiO2 nanocrystals hybrid with well controlled coating and strong interactions between TiO2 and the underlying GO sheets. The strong coupling could lead to advanced hybrid materials for various applications including photocatalysis. The prepared graphene/TiO2 nanocrystals hybrid has demonstrated superior photocatalytic activity in degradation of rhodamine B over other TiO2 materials, showing an impressive 3-fold photocatalytic enhancement over P25. It is expected that the hybrid material could also be promising for various other applications including lithium ion battery where strong electrical coupling to TiO2 nanoparticles is essential.Comment: Nano Research, in pres

A Traffic State Detection Tool for Freeway Video Surveillance System

AbstractTraffic state is one of the most important traffic flow parameters to both the traffic management center and the traveler. It's difficult to extract traffic data using surveillance cameras because of the wider field, panning and zooming of the surveillance cameras. To leverage the existing surveillance camera infrastructure, a surveillance video based traffic state detection system is proposed. The proposed system can estimate traffic flow speed and road space occupancy, and recognize three typical traffic states (congested, slow, and smooth). Experimental results show that the system had good adaptation and high accuracy in daytime

Growth of Pedagogical Practice in an Active Multidisciplinary FLC on Flipped Learning

Faculty Learning Communities (FLCs) have gained a lot of attention in higher education. Research has shown that they support student learning, faculty development, and congenial relations among faculty. This paper will shed light on a successful, multidisciplinary FLC comprised of nine faculty members who engaged in Flipped Classroom pedagogy over a two-year period. Guided by Cox’s (2015) recommendations, the FLC members sought to improve their students’ learning while at the same time enhance their instructional practice. Participation in the FLC led to (1) course redesign, (2) instructional redesign, (3) professional growth, and (4) a sense of community
