1无屏幕编程教育的兴起、目标与实践——基于社交媒体研究法(SMR)的Twitter大数据分析显示文摘近些年来兴起的无屏幕编程教育是基于有形用户界面(TUI),在没有屏幕支持的情况下,通过物理活动和有形设备来实现编程的教育。研究基于社交媒体研究法(SMR),采用定量与定性相结合的方式,对2018年1月1日至2020年6月30日期间,全球范围内推特(Twitter)推文中的四种无屏幕编程设备的数据进行分析,探究现阶段无屏幕编程教育的实践情况。结果表明:无屏幕编程教育在世界范围内受到广泛关注,多数人对其持肯定态度。无屏幕编程教育以最近发展区和支架理论为基本理论,通过主体四种角色的演绎,对学习者的认知能力、计算思维能力和学习品质,有着不同程度的良好促进作用。相较于有屏幕编程教育,无屏幕编程教育在帮助学习者感知真实世界方面,有着明显的优势。但是,如何将无屏幕编程合理、高效的引入课堂教学,依然是教育工作者亟需解决的一个难题。而且,TUI和人工智能技术发展仍有广阔的进步空间。随着技术的不断发展,无屏幕编程教育的普适度会有极大的提升。罗文蔚 陈蕙若 刘天娥 Ilene R.Berson 2020远程教育杂志2020,38,5:4
2自然辐射在电气石呈色中的作用显示文摘将经过大剂量γ射线辐射处理的锂电气石的光谱与那些自然样品的进行对比,淡红色自然样品与经辐射处理的样品表现出相同的光谱特征。近于无色的锂电气石中的Mn^(2+)吸收光谱特征在经辐射处理后消失,表明在辐射处理过程中发生了Mn^(2+)→Mn^(3+)的转变。对南加利福尼亚伟晶岩中电气石矿囊的辐射水平测试结果,已被用于计算在整个地质历史中自然样品所经受的辐射剂量,这些剂量一般相当于用来使经过室内热处理而发生褪色的锂电气石恢复原色所需的剂量。这表明,那些自然呈淡红色的电气石的颜色是由于受到自然辐射作用的结果,这种辐射作用仅仅在伟晶岩冷却到电气石褪色温度之下时才有效,它暗示了大部分的淡红色锂电气石最初在伟晶岩中生长时是近于无色的,仅仅是后来通过由于Mn经由离子化辐射产生的氧化作用而获得这种淡红色色调。Ilene M.Reinitz George R.Rossman 董秉宇 1990地质科学译丛1990,7,2:3

4Lignocellulose as an insoluble fiber source in poultry nutrition:a review显示文摘Extensive research in recent years into the use of various fiber sources in poultry nutrition has led to the perception that dietary fiber is more than a simple diet diluent.Several studies showed that the feeding of insoluble fiber sources such as oat hulls,sunflower hulls or wood shavings may affect digestive physiology and function improving chickens health and growth performance.In this context,the effect of lignocellulose as an insoluble dietary fiber source is increasingly being investigated.Lignocellulose is a component of plant cell walls and consists mainly of the insoluble carbohydrate polymers cellulose and hemicelluloses as well as the phenolic polymer lignin.Lignocellulose is chemically and physicochemically different from other insoluble fiber sources and thus possibly has different effects on poultry compared to traditional fiber sources.Several studies investigated the effect of dietary lignocellulose on growth performance,nutrient digestibility,gastrointestinal tract development and intestinal microbiota in broilers and laying hens.Studies differed in terms of feed formulation and lignocellulose inclusion level as well as products of different suppliers were used.The results obtained are inconsistent;beneficial,indifferent or detrimental effects of feeding lignocellulose were observed,so that a final assessment of lignocellulose as a“novel”insoluble fiber source is difficult.This review article summarizes the results of studies in connection with the feeding of lignocellulose to poultry,compares them with those that have used other insoluble fiber sources and illuminates the possible mechanisms of action.Ilen Röhe Jürgen Zentek 2021Journal of Animal Science and Biotechnology2021,12,4:2
