The present study investigates the effects of shared singing of a picture book on the Chinese vocabulary recall and retention of young bilingual learners in Chinese immersion programs using an experimental study *** hundred and six immersion kindergarteners from three different school districts in the *** were assigned to the experimental group(n=53)and the control group(n=53)at the class *** experimental group listened to a song-based storybook(also known as a story song)and shared in singing it,while the control group heard the same story,read aloud and shared in reading *** pre-test was administered to determine the participants’vocabulary level before the *** and delayed post-tests were used to assess their immediate recall and delayed retention of vocabulary targeted in the shared reading/*** t-test and one-way ANOVA analysis were employed to examine differences between the two groups in vocabulary recall and *** results showed that the experimental group achieved greater improvement in their vocabulary than the control *** finding suggests that shared singing can be a useful pedagogical tool for spoken vocabulary acquisition and retention in picture books.

Half-size adenosine triphosphate-binding cassette transporter subgroup G(ABCG) genes play crucial roles in regulating the movements of a variety of substrates and have been well studied in several plants. However, half-size ABCGs have not been characterized in detail in apple(Malus × domestica Borkh.). Here, we performed a genome-wide identification and expression analysis of the half-size ABCG gene family in apple.A total of 46 apple half-size ABCGs were identified and divided into six clusters according to the phylogenetic analysis. A gene structural analysis showed that most half-size ABCGs in the same cluster shared a similar exon–intron organization. A gene duplication analysis showed that segmental, tandem and whole-genome duplications could account for the expansion of half-size ABCG transporters in M. domestica. Moreover, a promoter scan, digital expression analysis and RNA-seq revealed that Md ABCG21 may be involved in root's cytokinin transport and that ABCG17 may be involved in the lateral bud development of M. spectabilis ‘Bly114’ by mediating cytokinin transport. The data presented here lay the foundation for further investigations into the biological and physiological processes and functions of half-size ABCG genes in apple.

解放战争后期,中共在占领城市后面临的一个重要问题就是如何处理好劳资关系。到1949年上半年,在不断总结各地城市工作经验的基础上,中共中央数次调整劳资关系的施政重点和方向,逐步摸索出一套实现劳资两利的具体办法和措施。而张闻天在1948年8月东北城市工作会议上的总结报告、在此基础上起草的《关于东北经济构成及经济建设基本方针的提纲》及其所引发的反响恰恰是与中共中央对劳资政策的迭次调整同步的。
