After analyzing interviews, all three AA participants self-selected their identity based on linguistic and physical contexts Thus, the findings suggest further research on AAs should consider cyber identity as a factor for bilingual speakers and compare it with Arabic speakers in their home country展开更多

Within the framework of Tajfel＇s Social Identity Theory, we examine the nature of identity and the many contexts in which it is shaped, mainly in reference to the ESL （English as a Second Language） classroom, but with broader implications for the students＇ experiences in Western classroom as a whole. We discuss the challenges facing not only students, but also faculty who wish to assist students in the formation of their new identities展开更多

This theory can be reduced to a number of the most typical mild-slope equations currently in use and provide a reliable research basis for follow-up development of nonlinear water wave theory involving porous bottoms.展开更多
