Although the library's Web site has become a standard tool for seeking information and conducting research in academic institutions, there are a variety of ways libraries approach the often challenging—and sometimes daunting—process of Web site development and maintenance. Three librarians at Western Michigan University explored issues related to this topic by conducting a Web-based survey, which was sent to two librarians—Web services and reference/public services—at 149 academic institutions. Survey findings are discussed, including references to Web departments and committees, priority setting, Web authoring, soliciting input, outsourcing, content management systems, redesigns, and user involvement. The participants’ insights regarding the greatest challenges and what seems to be working or not working well are also outlined, in addition to the authors’ suggestions for future research in this area.  相似文献

Statistical representations in the popular almanacs published at the end of the 19th century in the Habsburg Empire are an early prototype of visualizing statistical data for popular consumption and informing the public of an ethnically and linguistically differentiated society. The purpose of this article is to analyze these statistical representations using a combination of humanistic and visual analysis methods. The article focuses on the persuasive aspects (rhetoric) of diagrams, how they visualize knowledge and information (pragmatics), and the nature and structure of visual sense making (semantics). The form and content are related to the social context and materiality of images. These early popular diagrams predate functional design defined by positivism and science. They are interpreted as a historical practice of knowledge visualization in the context of a post-Enlightenment information regime (epitomizing rational government and the privileged position of statistics as instrument of increasing the efficiency and social control of the state). The modernist approach shapes the same information regime in information science discourse. The analysis—based on principles of information visualization and functional design requirements—shows that these examples possess a sound visual structure based on functional design criteria, and that they integrate cultural context without distorting the data. The advantages of naturalistic and culturally rich visualizations that enable ordinary citizens to acquire knowledge through leveraging simple visual reasoning skills, reliance on mental models, and narrative conventions are identified.  相似文献

With the increasing disclosure of public information and government data through information and communication technologies, along with the considerable privately generated data now available online, individuals have access to a huge volume of information. This “disintermediation” of (i.e., greater direct access to) public information may improve transparency and facilitate citizen engagement, but it may also overwhelm citizens not only with too much information but also by requiring them to take responsibility for gathering, assembling, and processing information. Despite the importance of effective information processing to successful use of available information, existing studies have not yet fully integrated this consideration into research on citizen use of e-government and open government data. Based on information processing theory—according to which individuals have a finite information processing capacity, which is affected not only by the quantity and quality of information but also by one's preferences for how information is presented—this study examined the effects of information presentation type (infographic versus text) on perceived information overload, along with the consequent effect of information overload on perceived website usefulness. We also investigated whether individual information processing propensity (visual or verbal) moderated the effect of information presentation type on perceived information overload. Our results showed that textual information tended to cause greater information overload, especially for those with a propensity for visual information processing, and that higher information overload was associated with a lower perception of website usefulness. Moreover, individual information propensity moderated the effect of information type on perceived information overload; people with visual information processing propensity were more strongly affected by the presentation of textual information. We discuss the implications of our findings for improving the communication of policy information through government websites.  相似文献

This study compared American and Japanese youth preferences for information sources and advertising content within the context of their respective cultures’ relationship and communication values. It found larger parental involvement and smaller media use for Japanese students. In an interesting reversal from cultural expectations, Japanese students ranked advertising as the most important information source and family as considerably less important, while American students did the opposite. Friends, not family, were the important interpersonal information source for the Japanese. Japanese consumers of the ‘90s may be ‘holonic’: able to be both individualistic and in harmony with groups important to them. The Japanese youth preferences for advertising content—indirect, symbolic, visual, emotional, with infrequent brand identification—were more in line with expectations.  相似文献

ABSTRACT

Information literacy aims to develop in students the necessary skills, knowledge, and dispositions to use information to solve problems, make decisions, and generate new knowledge. The literature is replete with examples of guiding students in accessing and evaluating information sources. Less prevalent is processing information—the heart of the inquiry. Analysis, inference, and synthesis are critical thinking skills that take information literacy beyond a bibliographic task. In this liberal arts college setting, librarians team with consultants in quantitative reasoning, writing, and presentation technologies to deliver an information literacy program that supports not only the search, but also the analysis, interpretation, synthesis, and presentation of findings and insights.  相似文献

Objectives: To create research bulletins for public health professionals that support knowledge transfer and evidence‐based practice. Methods: The methodology for the bulletins comprises five stages: scoping the topic, searching for relevant literature, selecting and obtaining relevant articles, assessing the quality of articles including evidence grading, producing a comment on quality and implications for practice and writing the research bulletin. An ABC—applicability, brevity and clarity—is considered at each stage to ensure that bulletins meet the needs of their intended audience. Results: Nine research bulletins have been produced on a range of health promotion topics. Bulletins are distributed to Welsh health professionals and are available online. The bulletins have developed since their inception to incorporate evaluation and feedback. Most significant among these developments has been introduction of an Implications for Practice section to promote uptake of research. Conclusions: Research bulletins support busy health professionals in evidence‐based practice by assigning a level of evidence, highlighting implications for practice and providing a comment on quality. The bulletins further develop the extended role for information professionals in knowledge transfer and dissemination.  相似文献

XTM的主题相关度的量化机制研究   总被引:3,自引:2,他引:1  
主题图XTM作为一种用于描述信息资源知识结构的工具,在信息和知识资源的整合领域有着广泛的应用前景。然而,在XTM技术框架中只定义了主题之间的关联,并没有给出相应的相关度评价方法,而且关联只局限在彼此有直接关联的主题之间,并没有定义间接关联。因此有必要为主题图引入相关度的评价,进而更清晰地理解主题图的语义结构。针对这一问题,本文在对XTM中主题关联语义结构的分析的基础上,通过划分主题关联种类,从XTM抽取出其树形的语义层次结构。在此树形结构的基础上,引入语义距离的概念进行对主题图的二级关联扩展和关联间语义相关度的计算。并在在相关算例的验证过程中,得到了较好的计算结果。  相似文献

“Crowdsourcing” is a practice that combines the concepts of “the crowd” and “outsourcing.” Introducing two articles on crowdsourcing in this issue, Nancy Proctor argues that—although we associate crowdsourcing with Web 2.0 and the social media revolution—its origins stretch back to the nineteenth century. Crowdsourcing is examined for its usefulness in creating radical new relationships between museum constituents, users, and institutions—putting the “wisdom of the crowd” in dialogue rather than in competition with formal institutional knowledge.  相似文献

This study evaluates the use of full-text databases amongst 425 undergraduate and graduate students in western New York. A review of literature implicated convenience, time issues, article retrieval option knowledge, and the appreciation and understanding of research article quality as potential predictors of full-text reliance. These variables were then evaluated via survey response and frequency counts, by conducting correlations, a one-way ANOVA, and stepwise regression analyses. The findings suggested that convenience, appreciation and understanding of research quality, and time management issues played a significant role in the prediction of student full-text reliance. These findings as well as the relationships among independent variables are discussed. Implications for instruction are then addressed.  相似文献

This study investigates the methods by which faculty obtain scholarly articles, books, and chapters. It focuses on full-text retrieval rather than discovery, drawing on a survey of 529 full-time faculty at U.S. colleges and universities in the Carnegie master's—large and master's—medium categories. When seeking articles, faculty rely mainly on their home-institution library collections, freely accessible online resources, and interlibrary loan. The situation is different for books, however; faculty most often purchase the books they need. Despite the continuing importance of formal access mechanisms (home-institution library collections and interlibrary loan), faculty rely on other sources of full text—informal access mechanisms—for 50% of the articles and 66% of the books they use. Nearly 25% get more articles from the open web than from any other source, and substantial minorities report heavy reliance on other sources. In particular, faculty sometimes use other libraries, often relying on current or past affiliations (e.g., part-time teaching) or on the user accounts of family, friends, and colleagues. Many are critical of their university library collections, but most are satisfied with freely accessible online resources and interlibrary loan.  相似文献

Due to doubts about the reliability of information in social media environments, and the epistemological beliefs of individuals who use these media, questioning the source of information and the perception of knowledge structure, is an important research topic. A structural model was constructed to explore structures associated with epistemological beliefs (justification for knowing) and online information-seeking strategies. The model included personality traits and information literacy. Data were collected from 190 university students. PLS-SEM was implemented in the analysis of the data. Analysis revealed that there was a significant relationship between epistemological beliefs specific to social media and information-seeking strategies, and information literacy structure has a direct effect on information-seeking strategies. Agreeableness and neuroticism were related with several dimensions of social media-specific beliefs. It was found that the personality trait which has the greatest effect on online information-seeking strategies is conscientiousness.  相似文献

The rising volume of electronic data, the growth in cloud computing and the need for secure and affordable large-scale data storage all contribute to the increasing reliance on data centers in society. This paper provides an overview of security issues relevant to data centers. We offer an aggregation and exploratory analysis of four audit reports of government data centers operating in the United States. Using the information security common body of knowledge to categorize audit findings, we identify the key issues from the reoccurring findings in the reports, particularly in regards to operations security, data center management, physical security, and disaster planning. The security of data centers has become a paramount concern for both government and the information technology industry. Both practitioners and academics can benefit from our research results because it provides insight into the key security issues facing modern data centers.  相似文献
