Beyond Cross-Language Transfer: Reconceptualizing the Impact of Early Bilingualism on Phonological Awareness

This study investigates effects of early bilingualism on phonological awareness that are abstract and beyond cross-language transfer. It extends the scope of previous research by systematically examining hypotheses derived from structural sensitivity theory. The theory postulates that having access to two languages renders structural similarities and differences between languages more salient, thus allowing bilingual children to form representations of language structure at a more abstract level. About 200 bilingual and monolingual kindergartners, first-graders, and second-graders in Taiwan participated in experiments taking into account the syllable structures, the phoneme inventories, and the phonotactics of the bilinguals' two languages. Findings from the study provide empirical support for structural sensitivity theory and indicate the need to reconceptualize the bilingual effect on metalinguistic development beyond cross-language transfer.     

The Heroine of Free China: A New Image of Diplomatic Envoys and the Female Body of the Liangyou Women’s National Basketball Team in the 1950s

The Civil War between the Kuomintang (KMT) and Communist Party that ended in 1949 caused a confrontation between the ‘Free China’ in Taiwan claimed by the Republic of China, the KMT that retreated to Taiwan, and the ‘New China’ established by the People’s Republic of China. The sport policies of the ‘Two Chinas’ were based on the respective political positions, which were affected greatly by the Cold War. Taiwan, ruled by the KMT affiliating with the camp of the capitalists led by the USA, was the revival base to connect with Chinese in several East and Southeast Asian countries and to connect with other Asian anti-Communist countries. Political and military policies contributed to Taiwan women’s basketball development during the Cold War in East Asia and the first national team named Liangyou thus emerged. The Liangyou’s life symbolized the beginning and the phased ending of women’s basketball development in Taiwan, and skilful players of noble character practised loyal diplomatic missions and publicized the strong body-mind heroine image of Free China. Their healthy and cheerful character along with a passion for basketball provided new ideas of women’s roles in post-war Taiwan. Trips for overseas competitions let players experience the outside world.

Bilingualism and morphological awareness: a study with children from general education and Spanish-English dual language programs

Existing research on the impact of bilingualism on metalinguistic development has concentrated on the development of phonological awareness. The present study extended the scope of existing research by focusing on morphological awareness, an aspect of metalinguistic awareness that becomes increasingly important beyond the initial phase of literacy development. Participants included three groups of fourth-grader children from the same school with comparable SES and non-verbal IQ: (a) monolingual English-speaking children from a general education programme, (b) Spanish-speaking children from a Spanish–English dual-language programme and (c) English-speaking children from the same Spanish–English dual-language programme. Researcher-developed measures of vocabulary and morphological awareness were administered. Results suggested that bilingual education can have a positive impact on the development of morphological awareness through cross-language transfer as well as increased sensitivity to structural language features. The findings contribute to a growing body of research on how bilingual experience may shape children’s metalinguistic development.

非正交面齿轮副动力学仿真分析

目的:探究非正交面齿轮与直齿圆柱齿轮组成的齿轮副在啮合传动过程中动力学特性,为基于面齿轮的传动装置提供动力学仿真分析参考.方法:首先根据啮合原理,利用包络法推导非正交面齿轮齿面的曲面族,再通过VS编写相应的计算程序,计算得到非正交面齿轮齿面上的有限个坐标点,然后使用catia曲面设计程序,得到非正交面齿轮模型,最后将非正交面齿轮与配对圆柱齿轮进行正确装配,使用动力学分析软件Adams进行啮合仿真分析.结果:通过对比分析表明,动力学仿真分析下的非正交面齿轮输出转速、法向载荷、圆周力、径向力和轴向力与理论计算基本一致.结论:验证了非正交面齿轮在啮合传动过程中有轴向力的产生,面齿轮传动具有周期性啮入啮出的特性.
