Births in China Reduced Slightly Year-to-year in Line with the Law of Population Change

On January 19,National Bureau of Statistics announced that births in 2015 were 16.55 million,a slight drop of 320 000 compared to 2014.How should we consider the reduction of births after implementation of the selective two-child policy？

A TEACHER DEVELOPMENT PROJECT IN CHONGQING UNIVERSITY

This article reports on an on-going teacher development project in Chongqing University. The project, run by the College of Foreign Languages, is aimed at promoting professional development among its teachers, particularly new teachers, by adapting the reflective model of teacher development. It outlines the project framework and discusses the impact of the project on the teachers involved.

Comparative Study of Faculty Evaluation of Teaching Practice between Chinese and U.S.Institutions of Higher Education

Along with the“massification”of higher education in China since the late 1990s,the issue of quality and excellence appeared at the top of China's higher education agenda.Since faculty evaluation of teaching is one of the major approaches adopted by China's higher education sector to pursue quality and excellence,it is valuable to examine the effectiveness of faculty evaluation of teaching practices adopted by the Chinese higher education institutions(HEIs).Study of current literature reveals some similarities and differences between the faculty evaluation of teaching policies and practices between Chinese and American higher education sectors.This paper examines the specific practices adopted by some top-tier Chinese HEIs and American elite colleges and universities,summarizes and analyzes the major differences and similarities of faculty evaluation of teaching practices between these two countries'top-tier HEIs,and discusses the applicability of the American models to the Chinese setting of higher education.Finally,a set of best practices regarding faculty evaluation of teaching are proposed for Chinese HEIs.

Valley-resolved transport in zigzag graphene nanoribbon junctions

Applying the transfer matrix and Green’s function methods,we study the valley-resolved transport properties of zigzag graphene nanoribbon(ZGN_(R))junctions.The width of the left and right ZGN_(R)s are N_(L)and N_(R),and N_(L)≥N_(R).The step/dip positions of the conductance G,the intravalley transmission coefficients(TKKand TK’K’),and the valley polarization efficiency PK’K correspond to the subband edges of the right/left ZGN_(R)that are controlled by N_(R)/N_(L).The intervalley transmission coefficients(TKK and TK’K)exhibit peaks at most of the subband edge of the left and right ZGN_(R)s.In the bulk gap of the right ZGN_(R),TKK’=TK’K=0,and PKK’=±1,the valley polarization is well preserved.As N_(R)increases,the energy region for PK’K=±1 decreases.When N_(L)is fixed and N_(R)decreases,G,TKK,TK’K’and PKK’exhibit more and more dips,and the peaks of TKK’(TK’K)become more and more high,especially when(N_(L)-N_(R))/2 is odd.These characters are quite useful for manipulating the valley dependent transport properties of carriers in ZGN_(R)junctions by modulating N_(L)or N_(R),and our results are helpful to the design of valleytronics based on ZGN_(R)junctions.
