Consumer health information-seeking behavior of members of a local Korean community in Tallahassee, Florida, was explored through semi-structured interviews. Questions explored how this community assessed the quality of health information, and what cultural values influenced their understanding of its quality. Accuracy and reliability were identified as the two most valuable quality characteristics. A commercial type of webpage was considered as a negative indicator for reliability, while information described in detail or displayed reiteratively was a positive indicator. In addition to functional quality criteria, nonfunctional characteristics such as sympathy were found. Above all, findings highlighted that cultural differences limited the use of health information. Quality based selection of information is an important part of a health information seeking process. Findings can give the designers of Web-based consumer health information systems important insights into how to support evaluation of the quality of health information by consumers, and how to reduce barriers to health information seeking and use caused by cultural differences.  相似文献

The outcomes of public libraries as perceived by individuals in the major areas of their lives are analyzed and the benefits as outcome types are systematized. The data are based on a representative sample of 1000 Finnish adults, ranging in age from 15 to 79. The results give a systematic account of the benefits in 22 areas of life that adults derive from using public libraries. These 22 benefits were reduced by factor analysis into three major outcome types: benefits in everyday activities, cultural interests, and career. The association of these outcome types with gender, educational levels, and age is also explored.  相似文献

Social media monitoring is gradually becoming a common practice in public organizations in the Netherlands. The main purposes of social media monitoring are strategic control and responsiveness. Social media monitoring poses normative questions in terms of transparency, accountability and privacy. We investigate practices of social media monitoring in four Dutch public organizations. Policy departments seem to be more strongly orientated towards monitoring, whereas organizations involved in policy implementation seem to be more inclined to progress to webcare. The paper argues for more transparency on social media monitoring.  相似文献

Constructivism is presented as the inexorable denouement of the qualitative versus quantitative paradigm war. Postmodernism is equated with constructivism, then deconstructed and critiqued in light of rhetorical strategy. The problem of universals is discussed and the solution is elaborated into objectivist pedagogy. Elkind (2005) is cited as an exemplar of postmodern doublespeak and, accordingly, logically refuted. The article concludes that a constructivist monopoly in education ideology is calamitous. The sole curative would be a fundamental change in philosophy; that is, an acceptance of objectivist epistemology.  相似文献

The shifting location of one institution within a knowledge-space that is itself dynamic is examined through a brief case-study of one of the constituent museums which, in 1985, became a part of the then newly established National Museums of Scotland. Through examination of the declared intentions of successive directors over the 151 year history of the institution successively known as the Industrial Museum of Scotland, the Edinburgh Museum of Science and Art, the Royal Scottish Museum, and the Royal Museum of Scotland, it attempts to reveal changes in that institution's perception of its own role, its corporate vision, and its sense of place within the social, intellectual and political landscape.  相似文献

The objective of this study was to investigate the effect of a socio‐cognitive teaching strategy on young children. It tests their understanding of the factors that friction depends on when an object is projected across a horizontal surface. The study was conducted in three phases: pre‐test, teaching intervention, and post‐test. The sample consisted of 68 preschool children who were assigned to two groups according to age and cognitive ability, based on their responses to a pre‐test. The children in the experimental group participated in activities that were approached from a socio‐cognitive perspective while the children in the control group participated in the same activities but from a Piagetian perspective. A statistically significant difference was found (Mann–Whitney U‐test), between the pre‐test and the post‐test, providing evidence for the effect of the socio‐cognitive strategy on children's understanding of a ‘precursor model’ for the concept of friction.  相似文献

A survey was conducted among library and information science (LIS) practitioners to examine the effect of the research methods course on LIS practitioners' work. Findings suggest the research methods course is a valuable component of the master's in library and information science (MLIS) program. Taking the research methods course increases LIS practitioners' research interest and assists them by helping them critically evaluate published literature and apply it at work, provide better assistance to library patrons, produce valid and reliable data to facilitate decision making, identify problems at work and design and implement studies to solve them, and write grants and for publication. Suggestions are made to improve the research methods curriculum and enhance the educational experience for LIS practitioners.  相似文献

In today's fast-paced world, anecdotal evidence suggests that information tends to inundate people, and users of information systems want to find information quickly and conveniently. Empirical evidence for convenience as a critical factor is explored in the data from two multi-year, user study projects funded by the Institute of Museum and Library Services. The theoretical framework for this understanding is founded in the concepts of bounded rationality and rational choice theory, with Savolainen's (2006) concept of time as a context in information seeking, as well as gratification theory, informing the emphasis on the seekers' time horizons. Convenience is a situational criterion in peoples' choices and actions during all stages of the information-seeking process. The concept of convenience can include their choice of an information source, their satisfaction with the source and its ease of use, and their time horizon in information seeking. The centrality of convenience is especially prevalent among the younger subjects (“millennials”) in both studies, but also holds across all demographic categories—age, gender, academic role, or user or non-user of virtual reference services. These two studies further indicate that convenience is a factor for making choices in a variety of situations, including both academic information seeking and everyday-life information seeking, although it plays different roles in different situations.  相似文献

Given the rising number of international environmental agreements, it is increasingly difficult for many developing countries to meet the basic commitments of compliance to Multilateral Environmental Agreements (MEAs). One major reason for non-compliance is an unforced restriction on enforcement information flow to the national environmental governance repository either due to policy regulations or, technological hindrance. The purpose of this paper is to highlight the importance of a global information technology framework for MEAs that will help in enhancing the flow of information from a grassroot level to a national repository and then serving to various international agencies involved in monitoring of enforcement and compliance to MEAs. The paper defines the current challenges in global and national-level environmental information gathering and analysis and then, explains the technological and policy framework model adopted in the Wildlife Enforcement Monitoring System (WEMS). The paper then argues that the WEMS model will be able to overcome the existing challenges hindering the information flow in a government framework.  相似文献
