Using an interview study, the author focuses on understanding the students＇ perspectives in relation to the label of model minority. The purpose of the study is to investigate how social, academic, and economic factors affect these students, including different outcomes in terms of school achievement and self-identity formation. The findings aim to help urban educators approach complex factors regarding minority students＇ educational opportunities. Comprehensive results identified that： （1） The concept of model minority significantly affects Asian American students at all levels of daily life; （2） Urban schools continue reinforcing social reproduction and producing perceptions based on socioeconomic background and intersectional discrimination; （3） The evidence in the study shows that school environments do not aid students in valuing their cultural capital; （4） Students from different social classes present different linguistic and behavioral patterns; and （5） Social stratification significantly influences students＇ perspectives in response to the Asian stereotype, self-identity, and racial hierarchy in school and society.展开更多

The mix-game model is proposed to mimic such phenomena. In a mix-game model there are two groups of agents： Group 1 plays the majority game and Group 2 plays the minority game. In this paper, we investigate such a case that some traders in real financial markets could change their investment behaviours by assigning the evolutionary abilities to agents： if the winning rates of agents are smaller than a threshold, they will join the other group; and agents will repeat such an evolution at certain time intervals. Through the simulations, we obtain the following findings： （i） the volatilities of systems increase with the increase of the number of agents in Group 1 and the times of behavioural changes of all agents; （ii） the performances of agents in both groups and the stabilities of systems become better if all agents take more time to observe their new investment behaviours; （iii） there are two-phase zones of market and non-market and two-phase zones of evolution and non-evolution; （iv） parameter configurations located within the cross areas between the zones of markets and the zones of evolution are suited for simulating the financial markets.展开更多
