信息茧房视域下移动知识服务使用影响因素研究

［目的/意义］信息茧房现象的存在,对用户使用移动知识服务具有一定影响,不利于用户对知识的学习与汲取。为探究信息茧房对用户使用移动知识服务的影响,以高校师生为研究对象,研究信息茧房效应下影响移动知识服务的因素,并提出相关建议,旨在为突破信息茧房、完善现有移动知识服务提供参考。［方法/过程］以信息茧房的主要成因为研究变量,构建信息茧房效应下用户使用移动知识服务的影响因素初始模型;利用问卷调查法收集相关数据,对初始模型进行分析检验并建立回归方程。［结果/结论］研究发现,用户特质(如心理动因和个人素养)、服务平台(如算法推荐技术)、信息内容(如内容权威性和有用性)和移动环境这4个方面均对用户使用移动知识服务产生影响。其中,用户特质对移动知识服务使用的影响最大;服务平台对移动知识服务使用也产生较大影响;此外,信息内容与移动环境也对移动知识服务具有一定影响。     

大学生手机依赖与认知失败的关系:冗思和焦虑的作用

采用手机依赖指数量表、认知失败问卷、冗思反应量表和焦虑自评量表,通过网络平台以大学生群体为研究对象进行调查,旨在探讨大学生手机依赖、认知失败、冗思、焦虑之间的关系,共收回有效问卷327份。结果发现:(1)大学生手机依赖显著正向预测认知失败;(2)冗思在大学生手机依赖与认知失败之间起部分中介作用;(3)冗思和焦虑在大学生手机依赖与认知失败之间起链式中介作用。研究表明,手机依赖除了直接影响认知失败,还通过冗思的独立中介以及冗思和焦虑的链式中介效应间接影响认知失败。

Analysis of the urban/rural broadband divide in Canada: Using GIS in planning terrestrial wireless deployment

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.     

Ipad远程开放教育教学初探

目前国内许多学校都开始尝试采用Ipad进行教学,教育人士对其褒贬不一,作为一种新型的移动学习媒体,它有着自身的优势,但也有一定的弊端。Ipad在远程开放教育方面有着较为明显的优势,也符合成人学员移动学习的习惯。在具备了充分的硬件设施和完善的教学环节设计之后,Ipad会为远程开放教育揭开一个新篇章。     

基于野外测量生成GIS数据方法分析

地理信息系统的核心,就是获取数据。搜集精准数据,才能描画完备的测量图。为满足测量需求,应不断深入解析,提供实时特性的精准数据。获取的GIS数据,被用在野外范畴的测量之中。确认数据生成特有的路径,提升GIS测定的精准性,便利后续的导入数据。     

Libraries and Spatial Literacy: Toward Next-Generation Education

The role of the library is to assist citizens in skills development critical to national interest and empowerment as literacy ambassadors, in general. Specifically, the work by the Federal Geographic Data Committee (1994) indicates that spatial literacy is for every citizen and not just a set of workforce specialists. Hence, the use of maps in decision making and problem solving will become fundamental to all professions, including library professionals. Thus, a spatial literacy awareness and rationale for such as standard job ability is discussed as a future librarian workforce proficiency and knowledge transfer medium.
