Results suggest that positive self-selection works for all types of migrant labors. Migrant workers with non-agricultural household registration or feinong hukou have no trouble to be integrated into the labor market of destination. They even have higher income and human capital return rates than local urban workers. Newly-arrived migrant peasants earn less than local labors. However, after a certain period, the skilled migrant workers catch up with local labors and are economically integrated into the local labor market while the low-skilled migrant group still earns less. Therefore the integration of migrant labors in urban labor market is yet a kind of segregated integration.展开更多

During the course of their sophomore year, 17 students participated and each student held two to seven individual reading sessions, to which they brought a self-selected children＇s picture storybook or children＇s novel they had finished reading on their own and orally read it to the researcher. Their oral reading and the discussion of each book with the researcher were audio recorded. To gain insight into the reading progress, these oral data were categorized and analyzed in terms of mispronunciation patterns, misunderstanding of vocabulary, misinterpretation of sentence or passage, and researcher＇s guidance. General findings of the 17 participants were presented in three categories： （1） vocabulary acquisition, （2） common comprehension problems, and （3） common pronunciation problems. Further analysis of two motivated students who read five to seven books revealed that （1） these two EFL learners gradually developed conscious awareness of their own pronunciation and comprehension errors and （2） they progressively acquired better competence to apply the pronunciation tips and reading comprehension techniques provided by the researcher during previous sessions. These findings and corresponding implications are discussed and further research suggestions are made.展开更多
