信息消费者的人口结构是决定我国居民信息消费的重要因素。根据2011年4月28日国家统计局发布的全国第六次人口普查数据,我国人口结构发生了重大的变化。为了弄清新的人口结构对信息消费政策的影响,本文首先概述我国人口结构的变化情况,然后在阐述我国居民信息消费发展现状的基础上,分析制约信息消费发展的新问题和新人口结构下信息消费政策的需求,最后提出完善信息消费政策的建议。 相似文献

为更好地了解受众对不同媒介产品的消费支出情况,本研究主要分析在微观环境下,受众的收入、对媒介的态度、媒介使用时间是如何影响媒介消费支出的。通过QQ的配额调查,获得基于广州市网民的1162个数据,研究发现在控制其他变量之后,三个自变量中收入与报纸、互联网的消费支出正向相关,而与杂志、电视、付费电视的消费支出无关。对媒介的态度,除了对电视的态度没有显著影响其消费支出外,对其他媒介(报纸、杂志、互联网)的态度都显著影响其消费支出,而且这些影响都是正向的。媒介使用时间全部与媒介消费支出正向相关。 相似文献

Competency theory predicts a miscalibration between students' self-assessments of their information literacy skills and their actual skill level. This study investigates whether such a disparity is evident among incoming freshmen who test as non-proficient on a standardized test of information literacy. In addition, this study analyzes Information Literacy Test scores and library anxiety test scores to provide preliminary data on whether library anxiety is related to information literacy skill attainment. Findings reveal that the relationship between information literacy skills and self-assessments predicted by competency theory are evident in the domain of information literacy. This study did not find an association between information literacy skill scores and total library anxiety scores. However, a significant negative correlation between information literacy scores and the subscale “knowledge of the library” indicates that as information literacy scores rise, anxiety scores related to a lack of knowledge of the library fall. The findings suggest that traditional information literacy instruction may not be effective with non-proficient students, who are unlikely to see themselves as needing or benefiting from such instruction. 相似文献

Student perceptions of the information professions and their master's program in information studies

Library and information (LIS) education is undergoing a major transformation. During this time of change, there is a pressing need for data from all stakeholder groups to support strategic decisions within individual schools and across the discipline as a whole; students are a key stakeholder group. This paper reports on a 4-year study of master's students enrolled in an institution undergoing a transition toward an iSchool. The self-administered questionnaire was distributed to students enrolled in the Master of Information Studies program at the University of Toronto eight times: to incoming students in the fall term for 4 years, and to the entire student body in the spring term of those same years. The data collected from approximately 1000 questionnaires indicate that students arrive excited about the information professions and optimistic about employment opportunities. As they progress through the program, however, many are not satisfied with professional aspects of their program. They want courses that prepare them for their first professional position, and opportunities to gain experience, which they believe will increase their employability. The data from the 4-year period revealed fluctuations over the years, which indicates the value of examining longitudinal data. 相似文献

This paper examines representations of urban domestic sphere and communication technologies in Playboy during the 1950s and 1960s. I argue that Playboy carved out a space for a seamless relationship between work (production) and leisure/free time (reproduction) in the domestic sphere, specifically the bachelor pad, which contributed to current notions of the live–work lifestyle. Combining work, consumption, and leisure through technology within the home permits the erosion of boundaries between work and free time. Consequently, advances in communication and entertainment technologies, consumerism and Playboy's celebration of the urban bachelor pad contributed to current definitions of the good life and reflected the paradigm shift to the post-industrial economy and the subsequent emergence of the knowledge economy. 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

Urban exploration is a hobby that involves visiting and capturing visual images of urban infrastructure often no longer used, including sewers, towers, factories, and military instalments. Hobbyists then frequently share their visual content via social media sites. The urban explorer's multi-layered construction of content offers an important opportunity to understand how people create information and share experiences and content in a hobby context. Data were gathered through face-to-face interviews with 17 urban explorers from Ireland and the United Kingdom and an analysis of urban explorers' digital presence. Results suggest that urban explorers believe their hobby serves both personal and civic purposes. Urban explorers' creative hobby behaviors further lead them to secretive information behaviors. 相似文献

Library orientations do their part to familiarize students with information literacy, and how the library fits within university life. But what if an orientation could give a student a strong introduction to their academic librarians? Research in academic libraries has noted that library anxiety remains a continual problem among current students. Valparaiso University librarians created the Get to Know Your Librarian program, which sought to make librarians accessible. Using humor and casualness, incoming students were “introduced” to librarians through a series of fun facts. This simple program was successful in helping alleviate incoming students’ library anxiety before their first semester. 相似文献
