Students’ perceptions of teacher impact on their self-directed language learning with technology beyond the classroom: cases of Hong Kong and U.S.

Teachers are important social agents who affect students’ cognitive and social behaviors, including students’ self-directed use of technology for language learning outside the classroom. However, how teachers influence student behaviors may vary across cultures, and understanding how teacher influences vary across different cultures is critical to developing culturally adaptive approaches to enhance students’ self-directed use of technology for learning outside the classroom. This study surveyed 418 undergraduate foreign language learners (190 from Hong Kong and 228 from the U.S.) on their intention to use technology for language learning outside the classroom, teacher influence and other psychosocial factors that may affect their technology use intentions. Structural equation modeling analyses of the survey responses indicated that teacher capacity support was consistently the most influential teacher practice affecting students’ self-directed technology use across the two cultures, whereas teacher affective support and teacher behavior support were significant predictors for Hong Kong students but not for U.S. students.

Supplementation with turmeric residue increased survival of the Chinese soft-shelled turtle (<Emphasis Type="Italic">Pelodiscus sinensis</Emphasis>) under high ambient temperatures

Turmeric residue (TR), containing residual levels of curcumin, is a solid by-product waste generated after the extraction and separation of curcumin from turmeric root. A feeding trial was conducted to evaluate the effects of TR on the survival of Chinese soft-shelled turtles (SSTs), Pelodiscus sinensis, under a high ambient temperature. A total of 320 female SSTs were assigned randomly to two diets: basal diet (the control group, n=160) and an interventional diet supplemented with 10% TR (the TR group, n=160). Our results demonstrated that supplementation of TR increased the SST survival rate by 135.5%, and superoxide dismutase (SOD) activity of SST liver by 112.8%, and decreased the malondialdehyde (MDA) content of SST liver by 36.4%, compared to the control group. The skin of the SST fed TR showed a golden color. High-performance liquid chromatography (HPLC) analysis indicated that the concentrations of curcumin in TR and the skin of the SST fed TR were (1.69±0.30) and (0.14±0.03) μg/g, respectively. Our observation suggests that supplementation of TR increased the survival rate of SST under high ambient temperatures. We speculated that the increased survival rate and tolerance at the high ambient temperature were associated with the anti-oxidation activity of curcumin from TR. Moreover, curcumin in TR could be deposited in SST skin, which made it more favored in the market of China. Our findings provide new knowledge and evidence to effectively reuse TR as a feed additive in animal and aquatic farming.     

雅俗共赏--诗词创作的最高境界

文章所讨论的雅俗共赏,是一种艺术审美理想与文学批评标准.雅俗共赏的优秀诗词作品有着鲜明的艺术特点,能更好地发挥社会作用,是诗词创作的最高境界.因此,诗词创作应力求用浅显通俗的语言,表达丰厚幽深的意蕴,使作品具有丰富的文本潜能,不同层次的读者都能欣赏.这一主张对解决当前诗坛关于诗词创作宜雅还是宜俗的争论,具有重要的启迪作用.     

论人格教育是素质教育的灵魂

在大学生素质教育中如何确立人格教育的地位和机制，是当前高校思想政治工作中的首要问题。大学生素质教育的根本任务以及国内教育现实形势和状况，都要求要从教育理念、时代要求、思想教育者意识、人才培养等几个方面牢牢把握大学生素质教育的灵魂一一人格教育。     

马克思主义理论发展路径的几点思考

当代马克思主义理论发展主要有三条路径：回归文本、借鉴西方学者的研究、面向时代和实践。在三种路径中，回到文本是前提，借鉴西方是参照，面向实践是根本。当前马克思主义理论发展亟需解决的问题之一，是超越路径依赖，实现不同研究路径的互补，使三种路径之间既保持一种必要的张力而并行发展，又相互借鉴和补充。实践路径是马克思主义理论发展的主渠道，为此，特别需要确立研究的主体意识、问题意识和超越意识。     

创建学习型企业的环境分析和对策思考

随着我国加入WTO，我国经济已加速融入到经济全球化的进程当中，越来越多的中国企业参与国际化竞争。中国建设银行、中国银行纷纷引进战略投资者，力争在海外上市，联想集团与IBM公司成功合作，生产笔记本电脑；海尔、中海油试图收购国外企业等等。全球化要求企业全球统一运作，整合全球的资源．如人力资源、资金、技术、设备和原材料；要求企业更加注重企业文化，注重员工和客户的管理，努力形成企业特有的习俗和行为模式，并将这些视为企业成功的关键因素。

Development of a badminton teaching system with wearable technology for improving students’ badminton doubles skills

The aim of this study was to develop a badminton teaching system using the wearable technology for improving badminton teaching and learning. This system can provide the similarity scores automatically by comparing a student’s movement and strength while playing badminton with a well-trained expert model. A quasi-experiment was conducted for eight weeks to evaluate the effectiveness of the developed system. A paired-sample t-test was analyzed to evaluate whether there is a significant difference between the pretest and posttest for the experimental group (EG) and the control group (CG) respectively. Also, an independent sample t test was utilized to compare the posttests between EG and CG. The results show that the badminton teaching system developed in this study could enhance the learning effectiveness of novice badminton learners. The results not only show that applying wearable technology, the Myo armband, can benefit learners’ badminton training, but also can demonstrate the importance of providing instant and adaptive feedback in motor skill learning.
