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

With the rapid development of Chinese e-government, Chinese citizens are encouraged to access e-government services as their convenience. However, the accessibility of Chinese e-government Web sites has been overlooked. This research study tries to provide an overview of the accessibility of Chinese local government Web sites. Three hundred twenty-four Chinese local government Web sites were examined to find out how accessible they are with reference to the Web Content Accessibility Guidelines 1.0 (WCAG) published by the World Wide Web Consortium (W3C). This research found that all the surveyed Chinese e-government Web sites failed one or more W3C's accessibility measures and thus many disabled Chinese people may have substantial problems to access them. Several valuable recommendations are made based on the research findings and the China's actual conditions. 相似文献

【目的】 调查开放获取期刊目录(DOAJ)收录的所有开放获取(OA)期刊的可达性和稳定性,以期为OA期刊长期保存和访问提供技术支持和参考。【方法】 采用网络调研法,结合Excel宏和人工测试,对2017年5月8日下载的DOAJ元数据中全部期刊进行可达性和稳定性的调查。该调查为期3个月,分3次进行。【结果】 在3次调查中,能够成功访问至少1次的期刊共9104种,占样本期刊总数的96.4%。虽然第1次和第2次调查的可达率接近,但是从单个期刊角度分析,在第1次调查中可达的期刊,在第2次调查中未必可达。【结论】 DOAJ收录的OA期刊可达性较高,但其稳定性还有待提高。经济发达的国家或地区的OA期刊数量较多、可达性较高。虽然各学科OA期刊数量差异较大,但是各学科期刊可达性差别不大。 相似文献

Fear appeals have long been used in persuasive messages to motivate people to perform adaptive behaviors. This research explored the influence of a fear appeal message concerning breast cancer on attitude accessibility. Messages advocating the efficacy of breast self‐examinations increased the accessibility of attitudes toward the adaptive behavior. Further, the accessibility of participants' attitudes toward the adaptive behavior predicted behavioral intentions to perform breast self‐examinations. Attitudes toward the threat became less accessible after exposure to a high fear‐arousing message, however. Analyses suggest that defensive reactions to the fear‐inducing message mediate the influence of the message on the accessibility of the attitudes toward breast cancer. Implications of these findings for models of fear appeals are discussed. 相似文献

ABSTRACT The Council on Public Liberal Arts Colleges (COPLAC) libraries websites were assessed for Section 508 errors using the online WebXACT tool. Only three of the twenty-one institutions (14%) had zero accessibility errors. Eighty-six percent of the COPLAC institutions had an average of 1.24 errors. Section 508 compliance is required for institutions receiving federal funding. While this study shows the need to correct the existing errors, the low error rate shows that COPLAC institutions have generally been conscious of accessibility standards and are working toward achieving fully accessible websites. Studies of the connections between average accessibility errors and the geographic locations of these institutions, the amount of federal funding received, and size were inconclusive. The main aim of the study is to demonstrate the need to check library websites using the free WebXACT tool. This tool offers suggestions for accessibility that should serve to decrease the number of pages that are inaccessible to patrons. 相似文献

U.S. federal websites are required to be accessible for people with impairments. However, despite the existing regulations and guidelines, many federal websites continue to be inaccessible, and accessibility policy statements available on federal websites often do not provide any useful information. This paper provides three contributions to the research literature: (1) an accessibility evaluation of 100 federal home pages using both human and automated methods, (2) a content analysis of existing website accessibility policy statements, and (3) a discussion of the relationship between actual Section 508 compliance and the existing accessibility policy statements on a website. The paper concludes with recommendations for improving policy related to Section 508 compliance for websites. 相似文献

User satisfaction is a crucial factor for continual usage of e-Government services and for the success or failure of e-Government projects. The main challenge for Jordanians is what are the key determinants of their satisfaction? This paper aims to identify the key factors that determine Jordanians' e-Satisfaction with Jordan's e-Government services portal. Based on an extensive review of relevant literature, five hypotheses are formulated and five factors are identified (i.e., security and privacy, trust, accessibility, awareness of public services, and quality of public services) that may affect the Jordanians' level of satisfaction towards using the Jordan e-Government portal (www.jordan.gov.jo). Survey data from 400 employees in four universities in the northern region of Jordan were collected and used to test the proposed hypotheses. Based on multiple linear regression and factor analyses, our empirical analysis demonstrates several key findings. These findings indicate the usefulness and importance to unveil the key drivers of e-Satisfaction so as to provide feedback in a set of recommendations that will enable creating e-Government portals which are compatible with citizens' needs, desires, and expectations. They also provide insights for both practitioners and governmental policy-makers to enhance e-Government portals via accounting diverse factors of technical, behavioral, managerial, and motivational aspects. Finally, implications and recommendations of these findings were discussed. 相似文献
