可视化微课资源对听障学生专业学习的补偿性研究

可视化微课是针对听障学生的缺陷进行补偿的一种介入式教学形式,听障学生因听分析器的缺失,对文本教材的阅读理解能力弱,现有手语配以多媒体的专业教学模式在知识的传递中欠直观、具象,造成听障学生接受信息有所缺失。可视化微课是将文本教材的内容设计转化为动态图形图像予以展现,符合听障学生读图看话习得知识的规律,能充分利用其视分析器接受信息。同时,可视化微课在专业教学的前、中、后三个阶段分别予以介入,能有效提升听障学生学习的积极性。该微课资源的可重复性和可逆性能极大的弥补听障学生对信息的高遗忘率,具有很好的缺陷补偿作用。     

微时代冰雪体育文化传播：价值、异化与消解*

采用文献研究、逻辑分析等方法,探究了微时代冰雪体育文化传播的价值、异化与消解。研究表明,冰雪体育文化微传播的价值特征体现在迅捷性、草根性和围观性等。价值异化体现在：在传播内容上,存在文化内涵与精神道德缺失;在传播形式上,存在过分技巧化与随意性;在传播效果上,存在信任危机乃至突出事件的可能性。建议：丰富文化内涵,提升文化品质;整合传播资源,创新传播形式;建构监管机制,提高传播质量。     

体育学科体系的分类:宏观、中观与微观

教育学科门类之下的"体育学",有望成为与"教育学"并列的一级学科,其学科体系的构建尚存在较多的问题:如体育学科特色不够突出、学科体系应用性和针对性不强、学科发展与体育教育问题研究缺乏互动等问题制约着体育学科的发展.以"科学发展观"为指导,采用文献资料和逻辑分析等方法,分析了体育学科体系分类三大实践领域存在的问题与不足,并试图从宏观、中观、微观的层次对体育学科体系的构建进行探索,提出了"一化四式"的发展趋势.     

兰州城市贫困住区空间分异特征及其影响因素

依据空间属性和社会属性,将兰州市区155个贫困住区分别归类为棚户区型与城中村型、多民族型与单一汉族型,运用最邻近距离指数、核密度估计和缓冲区分析等方法,揭示兰州城市贫困住区的空间分异特征及其影响因素。结果如下。1）棚户区型、城中村型和单一汉族型的贫困住区在市区层面均呈凝聚型分布,而多民族型贫困住区呈分散型分布。2）4类贫困住区都存在1个高密度区（带）和1个次高密度区;多民族型与单一汉族型还各存在1个较高密度区,但核密度最高值差异较大。3）在城市基础地理要素黄河、洪道和铁路两侧,不同类型贫困住区的数量与比重不同,亲疏关系差异较大。4）微观上的自然地理环境、历史格局和民族文化,宏观上的产业发展政策、住房供应体制和城市规划是影响贫困住区空间分异的重要因素。     

Caliphal Imperialism and Ḥijāzī elites in the second/eighth Century

ABSTRACT

This article contributes to the debate over the effectiveness with which late Umayyad and early ?Abbāsid caliphs negotiated their respective rights and duties with provincial elites during the second/eighth century. The focus is on the relationships that evolved between the caliphs and those elite families residing in the ?ijāz whose ancestors had helped to establish the Muslim community and the early caliphal empire in the mid-first/seventh century. The article's analysis centres on a series of four revolts in the ?ijāz over the second/eighth century and examines developments in the enthusiasm with which local elites either supported or opposed those revolts. This discussion demonstrates that, aside from a brief period during the first decades of ?Abbāsid rule, Umayyad and ?Abbāsid caliphs during the second/eighth century were actually quite successful at inspiring loyalty among the local elites of the ?ijāz.

Catégories et fonctions dans l’appareil de l’état au temps des Barmécides: un sondage sur le glissement entre les rôles

This essay is part of a wider research project aiming to define the components of the élite in power during the first ?Abbāsid period. Our present purpose is to verify if, and to what extent, the sliding among different public roles must be related with the “arbitraire” of the caliph or rather if it would be reasonable to discern in it some automatisms, some unregulated, although already applied paths. For this purpose, we carried out a survey of the figures who had offices in the administration of the ?Abbāsid state during the second half of the 2nd/8th century, i.e. the Barmakids and those who evolved with them on the political scene. In the initial stage, we confined our survey to the figures appearing in the Kitāb al-wuzarā’ wa'l-kuttāb by al-Jahshiyārī (d. 331/942), that is, with al-?ūlī's one, the most ancient collection of akhbār devoted to the vizirs. We actually think that this work has a historical as well as a symbolic significance. In our opinion the fact of having been produced inside the official milieu of the 4th/10th century increases its value as a source for the social history of the first ?Abbāsid period. Facing the problem of the sliding among different public roles, we tried to fix some criteria for the statistical analysis of this phenomenon, as well as to deduce how this could be used for the study of the social components of the ?Abbāsid élite.
