This study applies social network analysis to examining the pattern of relationships among networked users on Sina Weibo, the most popular social networking site in China. Focusing on verified (or V-) users and ordinary (non-V-) users, this study maps three centrality attributes of the social network, in terms of in/out degree, closeness, betweenness, along with cliques, in the dissemination and sharing of health-related information in the virtual community. Findings reveal a ‘spider web’ pattern of relationship among 50 V-users and 50 non-V-users during a regular period of time, highlighting the dominant position of the V-users for health-related information diffusion. Data analysis then reports a ‘drifting dandelion’ pattern of network among those who shared the information about a health-related incident on Weibo. This study also provides further information about the topical categories of health-related messages shared during the regular period as well as the topics concerning the incident. The implications of social networking media for health communication are also discussed.  相似文献

Social media have become an integral part of online news use, affecting how individuals find, consume, and share news. By applying the Theory of Reasoned Action (TRA), this study investigates the effects of motives, attitude, and intention on news-sharing behavior among German social media users (n = 333). Findings show that news-sharing attitude and subjective norms have a positive effect on news-sharing intention, which in turn has a positive effect on actual news-sharing behavior. Taken together, we see that a new media behavior in the early phases of its societal diffusion—like social media news sharing in Germany in 2015—can mainly be explained by a rational choice logic and is rooted in the motives of socializing and information seeking. This finding thus reflects the double nature of social media as a means for both information retrieval and social grooming.  相似文献

Journalists are frequently reporting about new and innovative products in news articles. Oftentimes, journalists use specific company and product information provided by enterprises that highlight a corporation’s social responsibility (CSR) activities. Based on framing theory and theory of reasoned action, an experiment was conducted to examine how types of CSR-framed news (either highlighting ethical, ecological, or philanthropic responsibilities of a company) affect news recipients’ product purchasing intentions. A mediation analysis showed that CSR-framed news indirectly and positively affected individuals’ purchasing intentions via company and product attitudes. No relevant differences could be detected for the specific type of CSR frame. Implications of the results are discussed.  相似文献

Abstract

Information and Communication Technologies (ICTs) incursion has brought a lot of changes to libraries activities. ICTs are used to manage libraries more efficiently and in meeting customers’ demands more appropriately at the right time. Despite the contribution of ICTs to library and information work, many libraries are yet to adopt these technologies especially in the acquisitions of library materials. This study was carried out in three selected university libraries in North West Nigeria. The objectives of the study were to: determine the influence of performance expectancy on academic librarians’ intention to use ICT for acquisition; establish the influence of effort expectancy on academic librarians’ intention to use ICT for acquisition; find out the extent of social influence and facilitating conditions on academic librarians’ intention to use ICT for acquisition and lastly to proffer recommendations. This study adopted a positivistic approach and used a questionnaire administered to 224 librarians to collect data in the three selected libraries. The study is guided by the Unified Theory Acceptance and Use of Technology (UTAUT) developed by Venkatesh. Findings from the study reveals that academic librarians are supportive on the use of ICT in their work; ICTs are significantly important, trainings were organized mainly for librarians on general use of ICT not only on acquisition, but also on the general issues related to library activities; librarians also have the knowledge necessary to use ICT for acquisition in their libraries. The study recommends among others that the parent universities should increase the funding of their libraries with adequate supervision, so that such funds are well utilized for ICTs application; university libraries should continually sponsor their academic staff on modern computerized ways of using ICTs to source for materials and the acquisition of information resources in academic libraries should be given all the seriousness it deserves by enacting legislation to allocate a reasonable percentage of the university’s budget to it.  相似文献

ABSTRACT

The modern learning environment is evolving at a rapid pace. Technology can help developers of preventive conservation tools and learning resources for collections professionals to increase their impact and reach. However, it is crucial to keep the needs of users, and gaps in skills and knowledge at the forefront. This article examines preventive conservation tools and resources developed by the Canadian Conservation Institute (CCI) and ICCROM (International Centre for the Study of the Preservation and Restoration of Cultural Property) over the past 30 years. In light of the results from a recent survey and research in the learning and development field, a set of orientations for future tool development are highlighted; these tools must be: need driven, user centered, emulating everyday experiences, social and informal, concise, mobile friendly, curated and open access.  相似文献

The study reviews the important role of information systems and their impact on educational planning and development. It also attempts to identify gaps in the provision of information needed by educational administrators who are key planners of education enterprise in Pakistan. It intended to determine their views about the development, objectives and needed services of a user centered information system for educational administrators. To achieve these objectives, a literature review, questionnaire survey and interviews were conducted. Thus, the educational administrators (i.e., registrars/deans/chairpersons in universities and principals of schools and colleges) were identified as the target population for the survey and were selected through cluster sampling. The respondents were from the Punjab province and Islamabad Capital Territory. In total, 297 (99%) responses were received and analyzed quantitatively. Interviews of purposively selected educational administrators were also conducted for a more in-depth understanding of respondents’ points of view. This triangulation of qualitative and quantitative methods helped in understanding the phenomena under study. Recommendations and conclusions are also drawn in the light of findings of the study. The study is the first one of its type that tried to probe the gaps in the process of accurate/valid information supply to educational administrators and planners. This gap is causing serious challenges for education in Pakistan.  相似文献

As an integral part of the Internet of Things (IoT), smart and connected sensors are emerging information and communication technologies that collect and transmit real-time data from various urban domains to inform decision-making. While smart sensors and IoT technologies have great potential to transform public service provision, their adoption in the public sector seems to be slow and incremental. Using cross-sectional data of 65 large and mid-sized cities in the United States, we examine what affects local governments' adoption of smart and connected sensors. We propose a path-dependence explanation for the incremental adoption and test if a local government's sensor adoption behavior is shaped by its existing policy priorities and managerial practices in related fields. Our results show that local governments' early adoption of smart sensors is likely to stem from their needs in specific policy domains. We also find that a local government's historical paths on urban sustainability and data-driven decision-making practices can predict its trajectory of sensor deployment, in terms of the scope and the integration of smart sensors across different urban domains. Surprisingly, a local government's e-government progressiveness is not a significant predictor. Our results confirm the incremental change in smart sensor adoption and provide implications for local governments' IoT planning.  相似文献

社交媒体时代受众的主体性地位逐渐凸显,新闻真实性可以理解为一种“信任性真实”,即受众所相信的真实。依据德国社会学家卢曼的分类,并结合对25位新闻从业者的深度访谈,本文从“系统信任”和“人际信任”两个维度对新闻的“信任性真实”进行了分析。笔者发现,“可视化”以及“交朋友”策略是社交媒体时代形塑传受之间“人际信任”的重要路径,不过需要指出的是,“信任”是完整实现新闻真实性的重要环节,但是新闻真实并不依赖于受众的信任,事实真实仍然是衡量新闻真实性的终极性标准。  相似文献

The technology acceptance model (TAM) has been used extensively to explain and predict users' acceptance of corporate information technology (IT). With the advancement in IT and the expanding popularity of internet applications in Gambia, e-Government has been a priority factor in rendering government services and in making information more accessible to citizens. This study shows how the TAM and e-Government initiatives would positively impact the Gambian government, despite the cultural differences within the country. This study developed a successful model of the Gambian e-Government system to assist Gambians with more efficient and cost-effective government operations. The study results reveal that the core constructs of the TAM have strong influences on user-intention towards e-Government products. This implies that the Gambian government can potentially utilize this study's TAM findings in other contextual settings to design and promote further implementation of e-Government systems.  相似文献
