Culturally diverse as they are, Asian-American children and youth share quite a few features among themselves. Most of them are children of foreign-born parents who came to America during the post-1965 immigration waves. As they grow up in culturally isolated environment, they are often faced with identity crisis. The society’s racial exclusion makes them feel like “forever foreigners,” while at home or community their American frame of reference is often in conflict with parents’ traditional values. As a result, they develop a flexible concept of identification. In fact, they are a part of but also apart from the American mainstream culture.  相似文献

孔子的终身学习思想是现代终身学习理论的历史滥觞。它包括"修己安人",强调学习者的自我完善和社会的和谐发展;"有教无类",提倡全员的学习;"不知老之将至",提倡全程的学习;"学无常师",提倡全方位的学习;"为仁由己",确立学习者的主体地位。深入挖掘孔子的学习思想并进行创造性的转化,对于建设学习型社会具有重要的现实意义。  相似文献

存储混合型是目前研究较多的控制释放体系 ,但由于其机理较为复杂 ,目前尚未建立合理实用的动力学模型 .以混合药膜包膜体系为研究对象 ,建立了释放动力学的简化模型并获得了解析解 .实验数据表明 ,该模型适用于描述药物装填量大于饱和溶解度的药物释放动力学行为 (相对偏差小于 3 % ) .根据该模型还从理论上分析了两种限定条件 (Dm Df和 Dm Df)下药物的释放特征 :当 Dm Df时 ,释放速率变为常数 ,达到零级释放 ,其释放速率与药膜无关 ,这为零级释放缓释体系如何控制释放速率和药物释放量提供了理论依据 :当 Dm Df时 ,药物的释放速率与药膜中的释放系数、溶解度和药物的装填量有关 ,与包膜过程无关 ,其释放过程类似于混合药膜缓释体系  相似文献

王弼的"自然"所取的乃是"自动然"之意,换一个说法也就是"无为,"但是这里的"无为"并不是不作为,它更确切的涵义乃是无意为、无心为,说的更明确一点也就是不作意。这乃是宇宙本体(大道)与天地万物共有的属性,把它视为任何其他东西都是不正确的。前人所以对王弼的"自然论"思想产生误解,除了对文本的阅读不够仔细外,"五四"以来所形成的西方思维模式的影响无疑也是其中的一个十分重要的原因。  相似文献

Elderly people are exposed to information technologies to keep them in touch with younger generations. Among various technologies, social network sites (SNSs) are seldom used by the majority of elderly people. To bridge the digital divide, it is necessary to dig deeply into the minority elderly users of SNSs. This study explores usage patterns of elderly Facebook users and further investigates how their diverse characteristics influence their usage and social circles. Three findings were derived. First, a sharp digital divide on SNSs does exist, and existing elderly Facebook users are mainly the dabblers. Second, personality profiling could predict elderly people’s SNS usage behaviors. Elderly users with a high level of openness and extroversion have more friends, status updates, and group memberships, and those with a high level of conscientiousness have fewer likes and status updates. Elderly users are likely to seek insightful content on SNSs. Moreover, they may have a higher degree of emotional stability than young users when using SNSs. Third, elderly people tend to build small social circles on SNSs that “copy” the family relationship in the real world; whereas, they build large social circles with interests and hobbies that are difficult to share in the real world. Based on these results, detailed suggestions are presented for better targeting elderly people in ways that move them toward SNSs.  相似文献

Research indicates that affective attitudes such as liking of a subject and confidence in one’s ability within a subject predict academic performance. Generally, immigrant minority students have positive attitudes and often have low academic performance. This study examines the self-efficacy and liking of subjects of New Zealand students and analyses the relationship of those attitudes towards academic performance in mathematics, writing, and reading by self-reported ethnicity. Data were obtained from the norming samples from the Assessment Tools for Teaching and Learning project in New Zealand. Of special interest are the relationships between attitude and performance for Pasifika and Tongan students in New Zealand. Tongan and Pasifika students had positive attitudes, but their mean scores were not significantly different to other ethnic groups except in writing for Tongan students. Tongan and Pasifika students did have lower academic performance than majority and Asian immigrant students in all three subjects. The correlation between liking and self-efficacy was fundamentally zero for Tongan and Pasifika students, while it was weakly positive for majority and Asian immigrant students. Together these results question the power of self-efficacy and liking attitudes to predict academic performance for immigrant students from agrarian or traditional societies. Further, the data suggest that ‘school effects’ are most likely explanations for this relationship, rather than lack of attachment, opposition, or deficiency theories.  相似文献
