Research has examined the relationship between traditional news media use and normatively important political outcomes such as knowledge and participation. However, most research fails to account for variations in the nature of news over time and across communities that could alter the fundamental relationship between exposure and these outcomes. Here two studies are presented—one with variation in news characteristics over time based on the American National Election Studies time series data and another with variation across local communities and newspapers within a single state during a single election year—to assess the hypothesis that the relationship between news use and political outcomes are moderated by natural variations in the nature of the news content and news outlets. 相似文献

This is an exploratory study of public library services in Singapore for young people (defined as those people between thirteen to nineteen years of age) who are wheelchair bound. The research was carried out originally in 2000, but the study still informs policy makers in the Singapore system. Three main research questions are explored:
-
What are the information needs of wheelchair-bound young people?
-
What are their perceptions of libraries and library services?
-
What are the problems they face in using library facilities and services?

Abstract This study assessed the level of scientific and natural resource knowledge that fourth-, eighth-, and eleventh-grade students in Maine possess concerning acidic deposition. A representative sample of public school students (N = 175) was interviewed on twelve concept principles considered critical to a full understanding of the acidic deposition problem. These included geological, meteorological, ecological, political, and economic concepts. Student knowledge was rated for each concept principle on a scale of complete, high partial, low partial, or no understanding. Common misconceptions were also noted. Generalized correct concept statements of current student knowledge are reported, as well as generalized missing concepts. Our conclusions have implications for teaching about acidic deposition and the design of environmental education curriculum materials based upon student knowledge. This information can help teachers better instruct students about current environmental problems and thus help learners gain an appreciation for the complex and multidisciplinary nature of science and the environment. 相似文献

Multi-organizational collaborations are increasingly important incontemporary science, but their formative processes have beenneglected by scholars in the social studies of science. Based onan examination of 53 collaborations in physics and relateddisciplines, we have found five types of formations.Collaborations that encountered greater difficulties in formingbecame more formal in their organization and management. 相似文献

Introduction
The aim of the study was to present a protocol for laboratory information system (LIS) and hospital information system (HIS) validation at the Institute of Clinical Chemistry and Laboratory Medicine of the Merkur University Hospital, Zagreb, Croatia.Materials and methods:
Validity of data traceability was checked by entering all test requests for virtual patient into HIS/LIS and printing corresponding barcoded labels that provided laboratory analyzers with the information on requested tests. The original printouts of the test results from laboratory analyzer(s) were compared with the data obtained from LIS and entered into the provided template. Transfer of data from LIS to HIS was examined by requesting all tests in HIS and creating real data in a finding generated in LIS. Data obtained from LIS and HIS were entered into a corresponding template. The main outcome measure was the accuracy of transfer obtained from laboratory analyzers and results transferred from LIS and HIS expressed as percentage (%).Results:
The accuracy of data transfer from laboratory analyzers to LIS was 99.5% and of that from LIS to HIS 100%.Conclusion:
We presented our established validation protocol for laboratory information system and demonstrated that a system meets its intended purpose. 相似文献37.

The centrality of written feedback is clearly seen from the proliferation of research in the context of higher education. As an increasingly expanding field in research, the majority of written feedback studies have been interested in investigating the technical aspect of how feedback should be given in order to promote student learning. More recently, researchers have focused on the socio-emotional factors at work in the feedback process, and advocated a dialogic approach to giving feedback in order to increase students’ understanding and active participation in the process. Moreover, to empower students to reflect on and make sense of the written feedback they receive, students’ personal characteristics, such as their prior and current knowledge, also play an important role. Nevertheless, reviewing studies on written feedback in the context of higher education shows a lopsided focus on the technical factors of written feedback, with little attention paid to the socio-emotional and student factors. This commentary aims at providing a broader definition of written feedback and identifying the dominant factors reported in research. A conceptual framework for looking into the factors at work in the feedback process is proposed and future research directions are suggested. 相似文献
