ABSTRACT

In the allocation of collection resources, it is important to have a good understanding of the teaching, instruction and research needs of faculty and graduate students. Data related to the use of electronic databases, journals, books, etc. is helpful; however, this data does not reflect the nature and impact of the information retrieved, but merely provides a general idea of the number of times items have been searched, retrieved or borrowed. By identifying and analyzing faculty and graduate students' publications and grant proposals to determine where researchers are publishing and what sources they are citing in their research, the Library can assess how well it is supplying a core of literature to meet research needs. To this end, this study analyzes the publication and citation patterns of food science faculty at the University of Arkansas for a fourteen-year period, 1990–2003. The findings show that faculty are using and citing materials ranging from 1 to 22 years old and that 85 titles account for only 13.67% of the total journals cited but for 77.75% of the citations. It is assumed that these 85 titles constitute the core journal titles for food science research.  相似文献

ABSTRACT

This study seeks to (1) identify the most productive source for current awareness information for the faculty and graduate students in the Department of Food Science and Technology at the University of Arkansas, (2) identify the update frequency and, hence, currency of information, and (3) identify effectiveness in retrieval. It is also hoped that this research will provide evidenced-based information for subscribing to a particular current awareness database for University of Arkansas food science and technology patrons and will allow us to direct patrons in this subject area to the best and most relevant resource for their current information needs. This paper reports the results of our evaluation of four current awareness sources on three search interfaces. These include Article 1st (First Search); Ingenta Connect; ISI Current Contents: Agriculture, Biology and Environmental Sciences (ABES); and ISI Current Contents: Life Sciences (LS). A listing of journals cited by faculty and graduate students in the Department of Food Science at the University of Arkansas for the period 1987–2003 was used to check against these databases. The extent of coverage of the journals and timeliness of update were used as criteria for the evaluation. The characteristics of the three interfaces are highlighted with respect to their effectiveness in providing a current awareness service.  相似文献

ABSTRACT

This study mapped the scholarly literature in the discipline of food science using co-citation analysis and explored the relationships found within this literature. Using the Journal of Food Science, an examination of a random sample of its articles published from 2000 to 2002 yielded a ranked list of frequently-cited journals. The top thirteen most frequently-cited journals formed a core set for further analysis. Using the SciSearch online database and a standard statistical package (SPSS), a two-dimensional map was created, relationships between the journals were studied, and the discipline of food science was explored. Food science journals tended to be either industry-specific (e.g., dairy science) or industry-general. The journals also tended to focus on either “pure” science (e.g., chemistry) or on applied science and technology. Of the thirteen journals mapped, six fell within the area of pure science, while four were in the area of applied science. Interestingly, three journals fell on the axis line dividing the two. At the same time, seven journals had the characteristics of being industry-general, while six were more industry-specific. The results are consistent with previous indications of the interdisciplinary nature of the field of food science, drawing as it does from many fields such as chemistry, microbiology, engineering, and agricultural science.  相似文献

ABSTRACT

“Agricultural communications” is an emerging field which is naturally both part of the “agriculture” and “communications” literature. However, it is much broader than just a subset of each. The coverage of standard databases such as CAB Abstracts and Communication Abstracts, while a good start, does not sufficiently cover the field. The Agricultural Communications Documentation Center (ACDC) at the University of Illinois at Urbana-Champaign has, over the last quarter century, worked to help define and collect this literature, by identifying relevant documents and entering them into a Web-searchable Microsoft Access database. An analysis of this database reveals important clues concerning the literature of agricultural communications. Of the nearly 30,000 documents within the ACDC collection, periodical articles comprise a little over one half, from a core list of 45 periodicals within the ACDC collection. More than one half of these core periodicals are outside the traditional agriculture and life science literature; approximately one third are scholarly journals.  相似文献

ABSTRACT

The purpose of this study was to develop a core list of journals for the field of agricultural economics. For this study, the holdings of members of the Agricultural Economics Reference Organization who represent agricultural economics libraries in the U.S. and Canada were surveyed. The resulting list of titles is compared to four similar lists, three in agricultural economics and the fourth in economics. Using any one list of journals is inadequate for collection development in agricultural economics. This survey list, along with other similar lists, can be used for decision making in selection and management of journal titles in the field.  相似文献

ABSTRACT

For a core journal to be developed, fruitful research articles, diversity, and continuity of research topics are essential. The main goal of this study was to trace the thematic evolution (historical development) of agricultural and natural resource academic journals (ANAJs) published by public academic institutions in Iran. To this end, the study analyzed 2,961 articles published from 1905–2003 in all publicly-funded ANAJs in all contributing agricultural and natural resource academic majors (subfields), examining the scientific domain, research subject, research method, citations, impacts, and the aggregation level of journals on academic majors and academic majors on journals. Less than 5% of the articles were qualitative and cited theoretical frameworks. Over 95% were quantitative articles as their publications progressed. Thematically, agronomy and plant breeding, with 31.68%, had the highest aggregation level among academic majors; whereas, agricultural extension and education, with 2.08%, had the lowest.  相似文献

ABSTRACT

A five year project to identify the most vital or core literature of the agricultural sciences was undertaken with results for the advanced countries as well as the Third World countries. Citation analysis and other bibliometric techniques were used to identify the most valuable literature for university-level instruction and research. Monographs in seven sub-disciplines of agriculture were evaluated by researchers resulting in a composite list of 8,400 volumes and in 363 core journals. Methods of analysis, evaluation techniques, and end products are described. Four of seven books describing the literature of agriculture have been published. A final product will be the transfer of the full text of the monographs and the journals for a five year period onto compact disk for use in the Third World. Because of copyright and other restrictions, the estimated 280 disk library will not be available to developed countries.  相似文献

ABSTRACT

As part of a larger, national survey, we performed an in-depth qualitative analysis using semistructured interviews and a standard set of questions. We wished to examine the research practices of faculty in agriculture, to understand what they need to be successful in their teaching and research. We plan to use this information to make improvements to research support services. The national survey results should help pinpoint opportunities for developing new research support services for agriculture. This study adds to library and information sciences by examining the specific needs of faculty members in agriculture and agricultural extension, groups that have been previously underrepresented in the library literature.  相似文献

ABSTRACT

After reviewing previously published literature in citation analysis and literature mapping, this study mapped the literature of food science and explored the relationships found within it. Using articles published in the Journal of Food Science from 2003 through 2005, a stratified random sample of citations was studied to yield a ranked list of the thirteen most frequently cited journals, which formed a core set for further analysis. Using the Science Citation Index and a standard statistical package (SPSS13), a two-dimensional map was created, relationships between the journals were studied, and the discipline of food science was explored. The study is an extension of previously published research covering the years 2000–2002 and attempts to analyze and compare the results across time frames.  相似文献

ABSTRACT

The University of Florida (UF) George A. Smathers Libraries is one of 19 institutions that participated in an Ithaka S+R Research Support Services investigation of agricultural sciences. The authors conducted a qualitative analysis of research support services based on one-on-one semistructured interviews with 15 faculty of the UF Institute of Food and Agricultural Sciences in 2016. A number of core themes emerged from the analysis of research practices in the local study at UF. Core themes included finding appropriate literature, data management issues and tools, repositories for sharing research products, and research dissemination. This report summarizes a subset of these results, focusing on themes related to academic library services that support agricultural scholars research needs.  相似文献

ABSTRACT

This paper analyzes the agricultural research output on energy crops and bioenergy for the period 2000–2005. Seven hundred eighty-three (783) articles gathered from CAB Abstracts from this period were analyzed to determine which disciplines have been publishing the most on this subject. The findings show that engineering-related research is most prevalent but that twelve distinct agricultural disciplines produced research on the subject during the study period, with varying degrees of productivity for each discipline. The actual agricultural energy resources being researched were determined by examining the 783 articles. The resources were divided into woody crops, non-woody crops, and animal-based resources, and the number of articles for each was tabulated. The three resource types were further examined to create a list of the individual crops or animal-based resources under investigation, along with the number of articles for each individual crop or resource. The core journal literature dealing with energy crops and bioenergy was determined by doing searches in both CAB Abstracts and Web of Science and tabulating the number of articles appearing in each journal. This allowed for the creation of a core journal list, ranked by the number of appropriate articles appearing in each journal.  相似文献

ABSTRACT

University of Nebraska-Lincoln (UNL) Libraries was one of 19 participants in a national study of the research practices and needs of agricultural researchers. Two UNL Libraries faculty members interviewed 11 UNL scholars during the summer of 2016. The ethnographic research approach revealed four core themes: interdisciplinarity and collaborations, scientific communication practices, scientific research data issues and practices, and challenges and opportunities. Illustrated by the sample of faculty comments presented here, the themes have direct implications for the UNL Libraries, while in other cases these point to concerns and opportunities for the university, the academy, and the nation.  相似文献
