Acculturation orientations of competing host communities toward valued and devalued immigrants

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.

Investigation of Poor Academic Achievement in Children with Duchenne Muscular Dystrophy

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.

永远的鹳雀楼

浩如烟海的中国古典文学作品里，咏唱名山胜川、雄关塞楼的篇章不知有多少；但真正能够令人吟咏不厌、永远留在人们记忆里的还是那些名作佳构、华彩篇章。人们在那里认识了惟见天际流的长江，认识了从天上而来的黄河，认识了岳阳楼、滕王阁……一首仅20字的小诗，也让天下人知晓了黄河岸畔有一座很有名气的鹳雀楼。     

将翱将翔弋凫与雁——漫谈古代的弋射

“女曰鸡鸣,士曰昧旦。子兴视夜,明星有烂。将翱将翔,弋凫与雁。”这出自《诗经·郑风·女曰鸡鸣》的诗句,描写了2500多年前一对夫妇晨起时的絮语。妻子说:鸡叫了。丈夫说:天还没亮呢。妻子又说:看天空中,启明星多么灿烂。丈夫答道:该去弋猎那翱翔的凫雁了。诗中所说的“弋”,是一种古老的射猎方式。弋射又称作“缴射”、“弋”,简单地说,就是用系着绳子的箭射猎飞鸟,它是以箭矢的牵引把绳子抛射到空中,靠绳子束缚飞鸟脖颈、羽翼的办法来获得猎物。弋射早已失传,不过,考古工作中发现不少与弋射有关的图像和实物,为我们了解这种古老而神秘的…
