Acculturation orientations of competing host communities toward valued and devalued immigrants     

Annie Montreuil  Richard Y. Bourhis   《Int J Intercult Relat》2004,28(6):507-532

This study explored how members of competing host communities may endorse different acculturation orientations towards valued and devalued immigrants settled in the bilingual city of Montreal. Francophone (N=422) and Anglophone (N=401) host community students from low-, medium- and high-ethnic diversity colleges completed the host community acculturation scale (HCAS) along with a questionnaire monitoring a range of social psychological correlates of acculturation orientations. Results showed that Anglophones were more integrationist and individualist and less assimilationist than Francophones. Both Francophones and Anglophones were more integrationist and individualist and less assimilationist, segregationist and exclusionist toward valued than devalued immigrants. Attending a multiethnic college had no influence on respondents’ acculturation orientations. The more welcoming acculturation orientations of Anglophones compared to Francophones was corroborated by results obtained with immigrants attending the French and the English colleges. Social psychological profiles of the respective acculturation orientations were similar across both host communities thus supporting the construct validity of the HCAS. Attitude toward co-national outgroup was a significant determinant of each acculturation orientations, suggesting that intergroup relations between rival host communities has an impact on acculturation orientations toward immigrants.  相似文献

刘桂华  师春生  贾冰怀  王启敏  黄安平  贾金榜  佟海青  高莹  姜思慧 《北京体育大学学报》1992,(4)

蛋白质分解供能的实质是某些氨基酸(主要是支链氨基酸)氧化供能。“副油箱”运动营养制剂以三种支链氨基酸(亮氨酸、异亮氨酸、缬氨酸)为主要成分,为耐力性项目运动员提供储备能源。经运动员服用实验证实,“副油箱”运动营养制剂能明显地改善心肺功能,减少乳酸积累和加快乳酸代谢,维持血浆氨基酸代谢平衡,增强肌肉力量,提高肌肉做功能力。  相似文献   

Investigation of Poor Academic Achievement in Children with Duchenne Muscular Dystrophy     

V. J. Hinton  D. C. De Vivo  R. Fee  E. Goldstein  Y. Stern 《Learning disabilities research & practice》2004,19(3):146-154

Duchenne Muscular Dystrophy (DMD) is a neurogenetic developmental disorder that presents with progressive muscular weakness. It is caused by a mutation in a gene that results in the absence of specific products that normally localize to muscle cells and the central nervous system (CNS). The majority of affected individuals have IQs within the normal range, generally with lower verbal than performance IQ scores. Prior work has demonstrated selective deficits on tests of verbal span and immediate memory. For the current study, 26 boys with DMD (and normal intellectual function) and their unaffected siblings were evaluated. Paired comparisons demonstrated that the children with DMD had significantly poorer academic achievement scores than their siblings, even though their vocabulary levels and home and educational environments were comparable. Children with DMD also had more behavioral concerns, physical disabilities, and poorer verbal memory spans. Linear regression indicated that behavioral concerns, executive function, and physical disability did not contribute substantially to academic performance, whereas performance on verbal span did. DMD presents with a selective developmental aberration in verbal span that has wide‐ranging consequences on learning skills.  相似文献

AI赋能公共图书馆适老化阅读服务研究--以杭州市为例     

李熠煜  朱彤 《新世纪图书馆》2022,(1)

杭州市图书馆运用人工智能等技术,在中心馆-总分馆体系下构建了全市共享的图书馆适老化服务,为老年人在数字环境下提供阅读服务。通过对杭州市公共图书馆的自助转借系统、无障碍服务和设施开发、数字服务平台、“悦借”网络渠道、多元服务方式的分析,肯定了AI赋能下杭州市公共图书馆适老化阅读服务的成效。同时指出,杭图的适老化服务存在对老年人心理层面的关注不够,高层次智慧馆员缺乏等不足。有效提升图书馆适老化服务需要满足老年读者的需求,利用智能设备提高服务效能,加强老年人阅读素养。  相似文献
