A great deal of work has been done to understand how science contributes to technological innovation and medicine. This is no surprise given the amount of money invested annually in R&D. However, what is not well known is that US science (R&D) investment is only one-sixth that of the annual revenue received by non-profit organizations (NPOs) in the US. The large majority of NPO revenues are devoted to the remaining landscape of altruistic causes – those not relying as heavily on scientific inquiry. Given this broader context, one might reasonably expect the non-profit world to have been as well characterized as that of scientific research. The unfortunate truth is that no map of altruistic missions and causes exists; the landscape of altruistic activity is virtually unknown. In this paper, we present the first maps of altruistic mission space. These maps were created using the text from websites of 125,000 non-profit organizations (NPOs) in the US. The maps consist of 357 topics covering areas such as religion, education, sports, culture, human services, public policy and medical care. The role of science in this altruistic landscape is examined. Possible applications are discussed. 相似文献

People with more political knowledge tend to have more coherent ideologies (Delli Carpini & Keeter, 1996; Judd & Krosnick, 1989; Stimson, 1975; Zaller, 1992). Drawing on prominent theories of attitude structure (e.g., Dinauer & Fink, 2005; Hunter, Levine & Sayers, 1976), we propose an explanation for this relationship, testing whether people who spend time thinking about how political concepts relate to one another are more likely to exhibit ideologically coherent attitudes (Judd & Krosnick, 1989). We find that participants who are instructed to participate in an exercise that requires them to think about how political concepts are related exhibit greater correlations between social- and economic-policy attitudes than nonparticipants and find some evidence that participants’ policy attitudes are more consistent over time. Contrary to expectations, there was no evidence of greater consistency between policy attitudes and underlying values, including party identification. 相似文献

Librarians at four different academic institutions concurrently completed curriculum mapping projects using varying methods to analyze their information literacy instruction. Curriculum mapping is a process for systematically evaluating components of an instructional program for cohesiveness, proper sequencing, and goal achievement. There is a dearth of documentation of how this process has applied to an information literacy curriculum; however, the benefits of an organized examination of course progression is clear. The librarians explored curriculum mapping using different methodologies and approaches in order to formulate a more strategic approach to teaching students information literacy skills. 相似文献

Local news media in the United Kingdom are undergoing a multitude of changes which have implications for our understanding of their value in local democracies. Despite the potential significance of these changes for those actors responsible for the provision of local news, very little research has investigated journalists’ and political communicators’ perceptions of the impact of these threats and opportunities. This article addresses this gap by presenting research which investigated the views of key stakeholders in the production of local news in a large city in the United Kingdom. The thematic analysis of 14 interviews evaluates how normative roles attributed to journalism, such as representing the public, acting as a watchdog, providing information, and running campaigns, are being fulfilled by different news providers in the current news ecology. 相似文献

Abstract French geography dissertations for the years 1985–2002 were examined for their salient characteristics in terms of degree production, dissertation type, institutional affiliation, and geographical reach. These dissertations offer a rich base of research conducted in a country known for its innovative geographical research and tradition. Particular strengths and trends were discerned and concentrations of institutional base and activity established. This study can serve as a template for other national research traditions and disciplines, and is especially useful for library science and those interested in characteristics of literature studies. 相似文献

The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature. 相似文献

Research on the literature of dietetics, apart from the broader field of nutrition, has not been reported in the literature. The purpose of this bibliometric study was to identify the core journals of dietetics and to determine the extent of indexing coverage for these journals. The study was conducted as part of a larger project, the Project for Mapping the Literature of Allied Health, sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association. Citations appearing in three journals between 1995 and 1997 were analyzed by the methodology common to studies in the project. Results revealed that dietetic literature relies heavily on journal literature and on those journals that are from associated health sciences fields. Of the indexing services examined, EMBASE/Excerpta Medica and MEDLINE provided the most complete coverage of the literature. The study's findings have implications for those involved with the literature of dietetics. 相似文献

Objectives
This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.Method
Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.Results
Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.Conclusion
Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field. 相似文献14.

Perfusionists select and operate the equipment necessary for monitoring, supporting, or temporarily replacing the patient's circulatory or respiratory function. There are over 3,000 perfusionists working in U.S. hospitals, medical and perfusionist groups, and as independent contractors. The purpose of this study was to identify the core literature of perfusion and to determine which major databases provide the most thorough access to this literature. This paper is part of the Medical Library Association Nursing and Allied Health Resource Section's project to map the literature of the allied health professions. It uses a bibliometric methodology to identify core journals. A group of forty-three journals was determined to make up the core journal literature of perfusion. MEDLINE provided the best overall indexing coverage for these journals, but librarians and perfusionists will wish to supplement its use with the Cumulative Index to Nursing and Allied Health Literature in order to access the journals written primarily for perfusionists. The study results can guide purchasing and database searching decisions of collection development and reference librarians, encourage the database producer to increase coverage of titles that are unindexed or underindexed, and advise perfusionists of the best access to their core literature. 相似文献

ABSTRACTThis study explores the conversational terrain of supportive conversations that vary in person centeredness (PC). Our team transcribed and unitized 223 conversations in which a discloser talked about an upsetting event to a listener trained to exhibit either low (LPC), moderate (MPC), or highly person-centered (HPC) comfort. Each utterance was coded for PC with a modified version of the traditional nine-level hierarchy. HPC-coded turns comprised 24% of HPC conversations, while LPC-coded turns comprised almost half of LPC conversations. Over 95% of turns in MPC conversations were classified as MPC. Additionally, turn-level coding and global ratings of PC differentially predicted outcomes. We discuss the implications of these conversational profiles in the context of how the PC content of conversations might aid in cognitive reappraisal. 相似文献

Korean politicians, particularly National Assembly members, have embraced the internet as a major means of communication for managing election campaigns and maintaining relationships with (potential) supporters during non-election periods. An increasing number of National Assembly members have become aware of the considerable influence that the internet has on their constituents, and thus, this study determines whether there are significant differences in online networks of National Assembly members and examines the relationship among National Assembly members and that between those members and their constituents to determine whether Twitter is used as a tool for communication as well as deliberation. The data were drawn from homepages, blogs, and Twitter pages of the members of the 18th National Assembly in April 2010. The results indicate that National Assembly members tended to have a more equal relationship in the Twitter network than in the homepage or blog network. More importantly, the members were linked mainly to fellow politicians in the same party, and thus, they used Twitter to communicate more with fellow politicians than with their constituents. 相似文献
