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

Rubrics are assessment tools that help students gain complex competencies. Our quasi-experimental study aimed to evaluate whether rubrics help teachers teach and assess mathematical reasoning in primary school and whether such an instrument might support student learning. In two Swiss cantons, 762 students in 44 5th- and 6th-grade primary classes worked on their reasoning competencies, and half of them additionally employed our standards-based rubric. All of the teachers received a 1-day training and participated in the final project evaluation. To standardise and support the teachers during the implementation phase, they received a detailed curriculum. An achievement test and questionnaires for students and teachers were administered before and at the end of the intervention. The results of our quantitative longitudinal analyses indicate that the rubric fosters the teachers’ perceived diagnostic skills but only indirectly impacts their use of formative feedback. Based on the students’ perceptions, however, we observed a direct effect of the rubric on formative feedback and student self-assessment. Effects on students’ outcomes could not be observed, but there are indications of effects mediated by self-regulation and self-efficacy. 相似文献

The form factors of handheld computers make them increasingly popular among K-12 educators. Although some compelling examples
of educational software for handhelds exist, we believe that the potential of this platform are just being discovered. This
paper reviews innovative applications for mobile computing for both education and entertainment purposes, and then proposes
a framework for approaching handheld applications we call “augmented reality educational gaming.” We then describe our development
process in creating a development platform for augmented reality games that draws from rapid prototyping, learner-centered
software, and contemporary game design methodologies. We provide a narrative case study of our development activities spread
across five case studies with classrooms, and provide a design narrative explaining this development process and articulate
an approach to designing educational software on emerging technology platforms. Pedagogical, design, and technical conclusions
and implications are discussed.

This study examines the reasons why authors publish in ‘predatory’ OA journals. In total, 50 journals were randomly selected from Beall's list of ‘predatory’ journals. Different methods, including WHOIS tracking, were utilized to query basic information about the selected journals, including location and registrant. Then, 300 articles were randomly selected from within selected journals in various scientific fields. Authors of the selected articles were contacted and sent survey questions to complete. A grounded theory qualitative methods approach was used for data collection and analysis. The results demonstrated that most of these journals were located in the developing world, usually Asia or Africa, even when they claimed they were in the USA or UK. Furthermore, four themes emerged after authors’ survey responses were coded, categorized, and sub‐categorized. The themes were: social identity threat, unawareness, high pressure, and lack of research proficiency. Scholars in the developing world felt that reputable Western journals might be prejudiced against them and sometimes felt more comfortable publishing in journals from the developing world. Other scholars were unaware of the reputation of the journals in which they published and would not have selected them had they known. However, some scholars said they would still have published in the same journals if their institution recognised them. The pressure to ‘publish or perish’ was another factor influencing many scholars’ decisions to publish in these fast‐turnaround journals. In some cases, researchers did not have adequate guidance and felt they lacked the knowledge of research to submit to a more reputable journal. More needs to be done by institutions and reputable journals to make researchers aware of the problem of ‘predatory’ journals. 相似文献
