Sociology Study 2011年第1期1卷 58-64页

作者： pam Nilan University of Newcastle Australia

Immigration, whether formally organised, or through refugee arrivals, remains a major source of population and workforce growth for Australia, This article undertakes a sociological analysis of the experiences of some young Muslim jobseekers in Australia. Some are recent migrants. Some are refugees. Others are second generation migrant Muslim youth. The Australian Government has identified Muslim youth as needing some special assistance to obtain paid employment. The study reported here investigated some of the obstacles faced by 18 young Muslim jobseekers in Western Sydney in 2009. Interviews were conducted with young Muslims of both sexes who were actively looking for work. It is concluded that the apparent ＂religious＂ ostracism of young Muslim jobseekers results in a highly counter-productive form of ＂cultural unemployment＂ that impedes the logic of the flow of migration.

Improving the cycling stability of metal sulfide-based anode materials at high rate is of great significance for advanced sodium ion ***,the sluggish reaction kinetics is a big obstacle for the development of high-performance sodium storage ***,we have rationally engineered the heterointerface by designing the Fe1?xS/MoS2 heterostructure with abundant“ion reservoir”to endow the electrode with excellent cycling stability and rate capability,which is proved by a series of in and ex situ electrochemical *** functional theory calculations further reveal that the heterointerface greatly decreases sodium ion diffusion barrier and facilitates charge-transfer *** present findings not only provide a deep analysis on the correlation between the structure and performance,but also draw inspiration for rational heterointerface engineering toward the next-generation high-performance energy storage devices.
