This annotated list is a guide to government and nongovernment sources of population, vital, and health statistics. It is arranged first geographically, giving sources for local, regional, state, national, and international statistics, and secondly by issuing body. Below the national level sources for only the California area are included, but they are representative of publications of similar health jurisdictions. The list is selective and concentrates on recent or regularly updated publications. A brief list of guides to other sources is included at the end. 相似文献

The content of the term software tools (STs) is discussed in the light of the current development trends in information and communication technologies. The list of possible classification areas of STs is presented that is critical to binding scientific and technical information (STI) to these areas. The main categories of objective representation of STs, available sources of STI on STs, and peculiarities of obtaining (retrieving) STI from these sources are characterized. A 28-group classification of STI about STs by contents (subject matter) is suggested. The areas where it is possible to utilize the suggested classification systems for describing and grouping STI units in databases and databanks are specified. 相似文献

Research on librarians' roles and responsibilities often takes the form of content analysis of job advertisements found in aggregators such as print journals and websites. Whether these ads help us better understand librarianship depends on how representative the source data is for each study—the line going from jobs, to job ads, then to job ad sources. Print sources dominate even in studies published after 2000. This study examines where reasonably representative job advertisements for academic libraries may be found by starting at the origin: the institutions themselves. It finds that commonly used print sources provide only a small fraction of available positions (the majority of which are those in doctoral institutions), and even the most comprehensive aggregator misses nearly half of the available positions. Taking job ad samples directly from institutions is time-consuming but provides more representative data. Smaller colleges pose a particular challenge for finding ads as few of them have openings at any one time and few of their ads appear in national aggregators. 相似文献

Medical personnel and medical librarians may tend to think of nutrition in medical terms and to forget its interdisciplinary aspects. For this reason, it is desirable for medical librarians to become familiar with a variety of sources of information on the composition of foods, nutrient values, food additives, and food protection. Many of these are government publications from such agencies as the U.S. Department of Agriculture, the National Research Council, and the Food and Agriculture Organization. Less familiar sources include nutrition materials from state agricultural experiment stations and extension services and important data published in a wide range of scientific or agricultural journals, which may be located through Nutrition Abstracts and Reviews, Food Science and Technology Abstracts, and the Bibliography of Agriculture. Sources of current information on nutrition research in progress include the Department of Agriculture's Current Research Information System (CRIS) and selective listings from the Smith-sonian Information Exchange. 相似文献

Bibliometric methods for the analysis of highly specialized subjects are increasingly investigated and debated. Information and assessments well-focused at the specialty level can help make important decisions in research and innovation policy. This paper presents a novel method to approximate the specialty to which a given publication record belongs. The method partially combines sets of key values for four publication data fields: source, title, authors and references. The approach is founded in concepts defining research disciplines and scholarly communication, and in empirically observed regularities in publication data. The resulting specialty approximation consists of publications associated to the investigated publication record via key values for at least three of the four data fields. This paper describes the method and illustrates it with an application to publication records of individual scientists. The illustration also successfully tests the focus of the specialty approximation in terms of its ability to connect and help identify peers. Potential tracks for further investigation include analyses involving other kinds of specialized publication records, studies for a broader range of specialties, and exploration of the potential for diverse applications in research and research policy context. 相似文献

Objectives:
The research determined (1) the information sources that family physicians (FPs) most commonly use to update their general medical knowledge and to make specific clinical decisions, and (2) the information sources FPs found to be most physically accessible, intellectually accessible (easy to understand), reliable (trustworthy), and relevant to their needs.Methods:
A cross-sectional postal survey of 792 FPs and locum tenens, in full-time or part-time medical practice, currently practicing or on leave of absence in the Canadian province of Saskatchewan was conducted during the period of January to April 2008.Results:
Of 666 eligible physicians, 331 completed and returned surveys, resulting in a response rate of 49.7% (331/666). Medical textbooks and colleagues in the main patient care setting were the top 2 sources for the purpose of making specific clinical decisions. Medical textbooks were most frequently considered by FPs to be reliable (trustworthy), and colleagues in the main patient care setting were most physically accessible (easy to access).Conclusions:
When making specific clinical decisions, FPs were most likely to use information from sources that they considered to be reliable and generally physically accessible, suggesting that FPs can best be supported by facilitating easy and convenient access to high-quality information.Highlights
- Medical textbooks were the most popular information source for family physicians'' (FPs'') clinical decision-making purposes, and medical journals were the most popular information source for the purpose of updating FPs'' general medical knowledge.
- FPs considered medical textbooks to be the most reliable (trustworthy) source, colleagues the most physically accessible, and continuing medical education the most relevant and intellectually accessible.
- The lowest ranked information sources across all four attributes were personal digital assistants, mental health professionals, pharmaceutical sales representatives, and other decision aids.
Implications
- The most popular information sources for clinical decision-making purposes among FPs were sources characterized as reliable and generally physically accessible.
- This study suggests the need for further research into interventions that target information access barriers in FPs'' practice settings and the promotion of reliable evidence for FPs'' clinical decision-making purposes.

Five ratios RH, RT, SH, ST and SZ derived from the three-part division of a set of sources in h-core, h-tail and uncited sources are defined. Dynamic changes in the three independent ratios RH, SH and SZ are studied for six selected topics. Data about these topics are obtained from the Web of Science for scientific papers and Derwent Innovations Index for technical patents. It is observed that all RH- and SH-values decrease when the time span widens, while SZ stays the same or increases; and that all RH- and SH-values for papers are larger than the corresponding values for patents. The shifted Lotka distribution is used in a theoretical interpretation of these empirical phenomena. 相似文献

The surviving gilded and polychrome altarpieces and sculptures in Portuguese churches, and the historical documents relating to them, offer an opportunity for understanding material and technological choices regarding gesso grounds. This paper focuses on the historical documentary research about gessoes — one aspect of a wider research project which also involved investigation of physical/chemical evidence, and archaeological reconstructions of gilded gesso grounds. Documentary research sheds light on the meaning of the terms used in historical documents, and on artists’ choice of materials and practices, production, and trade patterns of materials. It informs technological investigations and conservation decisions. The paper also stresses the importance of the evidence gained by using the historical and archaeological methodology applied in material culture studies, in which documentary, analytical, and experimental information complement and/or elucidate each other, leading to a comprehensive understanding of this technology. 相似文献

AIMS AND OBJECTIVES: The effectiveness of each of the 14 sources of acquired immunodeficiency syndrome (AIDS) awareness available to women and adolescent girls dwelling in a rural community in Imo State, Nigeria was measured in order to understand the relative contribution of the sources to the general knowledge about human immunodeficiency virus (HIV)/AIDS possessed by the women and the girls. METHODS: The details of the research methods adopted in this study, which involved 734 in-school and out-of-school adolescents and 434 women, have been described previously [Nwagwu, W. Di Nwanna and the reproductive health of the girl child in Imo State, Nigeria. Final Report (04 83064 000 GSS) submitted to MacArthur Fund for Leadership and Development, Abuja, 2006]. RESULTS: Friends and relatives emerged as the most effective source of AIDS awareness for women (29%), followed by community meetings (26%) and then television (20%), whereas the most effective sources for the girls were television (28%), followed by friends and relatives, and radio (17% and 14.4%, respectively). CONCLUSIONS: Each of the information sources listed made some contribution to the general knowledge about HIV/AIDS possessed by the respondents, although the level of awareness would have been low among women in the absence of friends and relatives, and among the girls in the absence of television. Information awareness programmes should be selected according to the needs of social groups and the most effective information sources concentrated upon. 相似文献

An analysis has been performed of several classifications for an extensive interdisciplinary field of nanotechnology. Objective difficulties have been identified in compiling a priori categorization of subject domain due to the increased volume of information flow in combination with the permanent emergence of new concepts and objects. The concept of a semistructured (dynamic) subject catalogue is proposed, which is borrowed from the database technology and is characterized by a variable and a priori unknown structure. 相似文献
