大面积建成区建筑密度遥感制图产品的精度验证

大面积建成区建筑密度遥感制图产品能够提供土地开发强度与人类居住环境的基础信息,是支撑人居环境研究和土地利用规划的重要数据。全球人类居住区层（global human settlement layer,GHSL）是由欧盟联合研究中心负责的大面积人居环境制图项目,建成区建筑密度遥感制图产品是GHSL重要的组成部分。目前该产品在欧美地区已经完成了GHSL建成区建筑密度遥感制图产品的验证。然而以中国为代表的东亚区域的建筑物形态和城市布局与欧美等区域有较大的差别,有必要在亚洲地区对其进一步验证。以中国的5个典型城市（上海、西安、长春、昆明和乌鲁木齐）大面积单体建筑物分布图为基础,通过聚合分析和邻域关键点搜寻匹配等算法,生成中国建成区建筑密度栅格图像产品作为验证数据,然后通过回归分析等方法,在像元尺度上对GHSL建成区遥感制图产品进行评价验证。结果显示,GHSL建成区建筑密度产品在较低分辨率下可以反映中国地区建筑密度情况,但在较高分辨率下在高值区过高估计密度。本研究可以为中国地区研发建成区建筑面积密度产品提供依据。

Verbal energy: attending to poetry

This paper contends that the current English curriculum does not adequately acknowledge the potential of poetry to make meaning through sound. It reflects on how sound may embody or communicate meaning, and seeks enhanced conceptions of this aspect of poetry for pedagogy and the curriculum. It begins with the attention the mainstream press gave to Seamus Heaney's remarks about Eminem, and progresses to consider Heaney's notion of ‘verbal energy’ in the light of developing conceptions of multimodal ‘new literacies’. It suggests that new approaches could accord with an oral heritage approach to poetry while also acknowledging the influence of the communicational environments pupils experience beyond English classrooms. Throughout, the author draws on material that has informed his on‐going Teacher Training Agency‐sponsored project exploring the ways in which pupils approach poetry as sound, soon to be detailed on web resources for the English teaching community.

Data assemblages,sentient schools and digitised health and physical education (response to Gard)

Michael Gard raises some important issues in his opinion piece on digitised health and physical education (HPE) in the school setting. His piece represents the beginning of a more critical approach to the instrumental and solutionist perspectives that are currently offered on digitised HPE. Few commentators in education, health promotion or sports studies have begun to realise the extent to which digital data surveillance and analytics are now encroaching into many social institutions and settings and the ways in which actors and agencies in the digital knowledge economy are appropriating these data. Identifying what is happening and the implications for the concepts of selfhood, body and social relations, not to mention the more specific issues of privacy and the commercialisation and exploitation of personal data, requires much greater attention than these issues have previously received in the critical social research literature. While Gard has begun to do this in his article, there is much more to discuss. In this response, I present some discussion that seeks to provide a complementary commentary on the broader context in which digitised HPE is developing and manifesting. Whether or not one takes a position that is techno-utopian, dystopian or somewhere in between, I would argue that to fully understand the social, cultural and political resonances of digitised HPE, such contextualising is vital.     

论高中历史教学方法的转变--基于全球史观的视角

全球史观作为当前史学界较为赞同的观念,其新的史学理论与方法是对传统世界史中“欧洲中心论”的批判。不仅给史学研究指出了新的发展方向,也为中学历史学习提供了新的视角。高中历史新课程中借鉴和吸收了全球史观的观点,也使得历史教学方法的转变具有了契合性,推动了高中历史课程改革的进程。     

企业家全球竞争压力感知与企业国际化扩张行为的关系研究

基于合作全球图的专利国际合作分析

为辅助国际合作分析与管理,提出合作全球图。经过分析现有网络图、网络地理组合图,合作全球图将合作网络图融合全球地理图,以点的大小表示合作次数,用边揭示合作行为,在全球地理图上完整显示国际合作网络信息。实验表明,锂电池专利合作全球网络中,国家合作被北美合作网络、西欧合作网络、东亚合作网络主宰,美国、德国、法国、日本、韩国、中国是当之无愧的六强霸主,Centre Nat,Univ Tsinghua分别位居申请人合作的冠亚军。由此可见,合作全球图有助于国际合作分析、国际合作管理等。
