Analysis of the urban/rural broadband divide in Canada: Using GIS in planning terrestrial wireless deployment   总被引：3，自引：0，他引：3

Millions of Canadians residing in Canada's northern, isolated, rural, and remote communities do not have broadband Internet access. This situation has led to a national “broadband divide.” That is, the deployment of wireline broadband is very limited in Canada's northern, isolated, rural, and remote areas because of the significant expense of installation and maintenance of the wired infrastructure needed to reach dwellings in these locations.Terrestrial broadband wireless technology, on the other hand, does not entail the same kind of physical infrastructure. As a result, there are dramatic changes in how spatial considerations affect the provision of broadband Internet services (BIS) to areas beyond the urban zone. In particular, the spatial question is now focused on assessing the capacity for different technological solutions to reach profitable population bases, and brings to the forefront organizations that are developing non-line-of-sight (NLOS) technologies that would permit wireless Internet access over much greater distances than current solutions.We begin this paper by establishing the importance of broadband connectivity to Canada's northern, isolated, rural, and remote communities. This discussion comments on the role of the Government of Canada in the provision of broadband connectivity to residents of these communities, and outlines the current regulatory issues that govern wireless services and policy formulation.The second part of the paper illustrates the use of geographic information system (GIS) approaches in the study of wireless broadband planning and deployment. Case study findings suggest that GIS applications can make a significant contribution to the analysis of wireless deployment planning, to the understanding of the relationships between wireless signal sources and consumers, and to the spatial configuration of terrestrial wireless broadband networks. We conclude the paper by discussing how the GIS approach employed could be used to inform the public policy process with regard to increasing access to broadband Internet services in all regions of the country, and thereby providing the opportunity for all Canadians, regardless of location, to fully participate in the Information Society.  相似文献   

Finding the missing Einsteins: Expanding the breadth of cognitive and noncognitive measures used in academic services     

《Contemporary educational psychology》2020

Education researchers, policymakers, and practitioners are concerned with identifying and developing talent for students with fewer opportunities, especially students from historically marginalized groups. An emerging body of research suggests “universally screening” or testing all students, then matching those students with appropriate educational challenges, is effective in helping marginalized students. However, most tests have focused on two areas: math and verbal reasoning. We leverage three nationally representative samples of the U.S. population at different time points that include both novel cognitive measures (e.g., spatial, mechanical, and abstract reasoning) and non-cognitive measures (e.g., conscientiousness, creativity or word fluency, leadership skill, and artistic skill) to uncover which measures would improve proportional representation of marginalized groups in talent identification procedures. We find that adding spatial reasoning measures in particular—as well as other non-cognitive measures such as conscientiousness, leadership, and creativity—are worthwhile to consider for universal screening procedures for students to narrow achievement gaps at every level of education, including for gifted students. By showing that these nontraditional measures both improve proportional representation of underrepresented groups and have reasonable predictive validity, we also broaden the definition of what it means to be “gifted” and expand opportunities for students from historically marginalized groups.  相似文献   

Spontaneous spatial strategy use in learning from scientific text     

《Contemporary educational psychology》2017

Two studies explored the role of the spontaneous use of spatial note-taking strategies (i.e., creating maps and drawings) and spatial ability in learning from a scientific passage. In Study 1, college students read and took notes by hand on a 10-paragraph scientific passage about the human respiratory system. Students tended to use verbal strategies such as lists (on 48% of the paragraphs), outlines (29%) and running text (15%), but also used spatial strategies such as maps (28%) and drawings (11%). Regression analyses indicated that spatial ability and the use of spatial strategies (maps or drawings) significantly predicted learning outcomes, with spatial strategy use explaining additional variance beyond spatial ability. In Study 2, students read the same scientific passage and took notes either by hand on paper (paper group), by hand on a large whiteboard (whiteboard group), or on a laptop computer (computer group). A similar general pattern as Study 1 was found for the paper group, but this pattern was not found for the computer or whiteboard groups, suggesting that the relationships found in Study 1 might depend on the note-taking medium. Results also indicated that students in the paper and whiteboard groups spontaneously used more spatial strategies, whereas the computer group tended to use verbal strategies (i.e., words only), suggesting that different note-taking contexts encourage different strategies.  相似文献

王开泳  邓羽 《中国科学院大学学报》2016,33(6):775-782

空间联系强度是城市群发展阶段、态势、功能定位的重要表征.在大数据背景下，随着移动终端的普及和网络联系平台的广泛使用，人流在不同地区的空间移动能够得到较准确的统计和表达.在总结以往城市群空间联系研究方法的基础上，提出一种新的基于微博数据判别城市之间空间联系强度的方法，弥补了由于缺乏城际通勤数据而导致的传统空间联系强度判别方法的不足.新方法可以较准确地判别城市群地区各个城市的空间联系强度与组织类型.  相似文献   

Exploring Verbal,Visual and Schematic Learners' Static and Dynamic Mental Images of Scientific Species and Processes in Relation to Their Spatial Ability     

Sulaiman M. Al-Balushi 《International Journal of Science Education》2013,35(3):460-489

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners.  相似文献

论长三角城市群空间演进中的竞争策略     

张攀  徐长乐 《华东师范大学学报(哲学社会科学版)》2007,39(5):111-116

在经济全球化、区域一体化、地方行政力量调整和可持续发展的外部背景下，长三角城市群空间格局正经历着变革性的演变，城市群竞争力的塑造也面临着诸如行政力量变动、基础设施消长、生态控制等突出的问题。而从国外城市群空间开发和竞争力提升的经验来看，空间结构扁平化、空间联系多向性和城市群空间特性服务于地域综合开发的趋势是竞争力得以获得的途径所在。因此，未来的长三角城市群在借鉴国外经验解决自身发展障碍、参与全球竞争时的具体策略在于制度整合国际化、经济发展空间均衡化、竞争永续性和核心边缘地区统筹化。  相似文献
