This study surveys the development of Alzheimer's disease (AD) in the research literature, the scientific community, and the journals containing AD papers over a 35-year period. Research papers on AD published from 1983 to 2017 in journals indexed in the Web of Science were analyzed in seven five-year periods. The number of AD papers increased from 1,095 in 1983-1987 to 50,532 by 2013-2017 and in the same time period, the number of participating countries went from 27 to 152. The US was the most prolific country throughout, followed by several European countries, Canada, Australia, and Japan. Asian countries have emerged and by 2013-2017, China surpassed all but the US in productivity. Countries in Latin America and Africa have also contributed to AD research. Additionally, several new non-governmental institutions (e.g., ADNI, ADI) have emerged and now play a key role in the fight against AD. Likewise the AD scientific publishing universe evolved in various aspects: an increase in number of journals containing AD papers (227 journals in 1983-1987 to 3,257 in 2013-2017); appearance of several AD-focused journals, e.g., Alzheimer's & Dementia, Journal of Alzheimer's Disease; and the development of special issues dedicated to AD. Our paper complements the numerous extant papers on theoretical and clinical aspects of AD and provides a description of the research landscape of the countries and journals contributing papers related to AD.

Aim This study charts the growth of the scientific journal literature on headache for 30+ years (1983-2014). Methods Using the Web of Science, articles published in four two-year periods (1983-1984, 1993-1994, 2003-2004, 2013-2014) from journals indexed in the Science Citation Index Expanded database were retrieved and analyzed. Results From 1983-1984 to 2013-2014, the scientific literature on headache increased nearly fourfold (3.8) from 468 to 1776 articles; the number of participating countries more than doubled (26 to 67); and the two most prolific countries in each period were the USA and Italy. While several European countries (Italy, Germany, UK and Denmark) were among the top 10 in each period, the notable appearance of Turkey, China and Brazil among the top 10 in 2013-2014 indicates the growing geographic spread of publications on headache research. Meanwhile, the comet-like distribution of journals has not changed: two journals, Headache and Cephalalgia, persist throughout as the nucleus, with the tail increasing more than threefold from 141 journals in 1983-1984 to 462 in 2013-2014. Conclusion Our study follows the recent growth and spread of the scientific literature on headache research and should stimulate further bibliometric investigation in this field.

Increasingly, e-books are becoming alternatives to print books in academic libraries, thus providing opportunities to assess how well the use of e-books meets the requirements of academics. This study uses the task-technology fit ( TTF) model to explore the interrelationships of e-books, the affordances offered by smart readers, the information needs of academics, and the 'fit' of technology to tasks as well as performance. We propose that the adoption of e-books will be dependent on how academics perceive the fit of this new medium to the tasks they undertake as well as what added-value functionality is delivered by the information technology that delivers the content. The study used content analysis and an online survey, administered to the faculty in Medicine, Science and Engineering at the University of New South Wales, to identify the attributes of a TTF construct of e-books in academic settings. Using exploratory factor analysis, preliminary findings confirmed annotation, navigation, and output as the core dimensions of the TTF construct. The results of confirmatory factor analysis using partial least squares path modeling supported the overall TTF model in reflecting significant positive impact of task, technology, and individual characteristics on TTF for e-books in academic settings; it also confirmed significant positive impact of TTF on individuals' performance and use, and impact of using e-books on individual performance. Our research makes two contributions: the development of an e-book TTF construct and the testing of that construct in a model validating the efficacy of the TTF framework in measuring perceived fit of e-books to academic tasks.

This paper surveys aspects of the research productivity and visibility of Australian LIS educators as reflected in publications retrieved from eight relevant databases. Searching was restricted to educators serving for at least two years in Australian LIS programs from 1959 to 2008; the records obtained were downloaded and checked for accuracy. The results show that fewer than five percent of educators, generally with long service, produced over one-quarter of all journal articles, while nearly one-third of educators authored no articles. About three-quarters of all journal articles were single-authored; however, multiple authorship has increased over time, especially since 2000. Nearly one-half of all articles were published in Australian national journals. As these journals were indexed only in national and LIS-specific databases, such databases must be included to obtain a reliable picture of Australian LIS research productivity.

Extensive data document the distribution of library and information science (LIS) educators in Australia from 1959 to 2008: from a slow beginning in the 1960s, to rapid growth in the 1970s, relative stability in the 1980s, and a persistent decline from the 1990s. Other characteristics of Australian LIS educators over the 50-year period are presented, including: previous positions held before entering academia, what and where academic qualifications were obtained, academic positions/ranks by gender, mobility within Australian higher education institutions, and years spent as Australian LIS educators. Although there has been a steady decline in the number of Australian LIS educators since the 1990s, the level of academic qualifications and percentage with doctorates have risen, thus conforming to a major requirement of academia; however, the relative decline in junior academic positions is a worrying trend. The analysis of changed characteristics over time helps define who Australian LIS academics are, and additionally provides data that contributes to LIS academic workforce planning.

Using the SCI-expanded database, this study provides a quantitative description of the development of the research involving matrix metalloproteinase (MMP) over a period of 20 years. From 1986 to 2007 the scientific literature related to MMP increased sevenfold (397 papers in 1986-1987 and 2834 in 2006-2007). The number of countries participating in MMP-related research doubled during this period (33 in 1986-1987 to 67 in 2006-2007), and the USA continually remained the leader. Several industrialized nations (Japan, Germany, UK, Canada, and France) also continuously played important roles, with some emerging Asian countries joining the top 10 most productive countries in 2006-2007: China (ranked 5th), South Korea (6th), and Taiwan (10th). The MMP-related literature was distributed among a continuously growing number of journals (188 in 1986-1987, 527 in 1996-1997, and 913 in 2006-2007) and The Journal of Biological Chemistry remained the most prolific throughout the entire period. The development of the research involving MMPs during the past two decades was also characterized by a progressive transfer of interest from basic research to clinical medicine; cell biology and pharmacology were important routes of investigation generally pursued by researchers. Journals dedicated to oncology have progressively risen to the top 8 most prolific journals during the 20 year period analyzed. Menée sur la base de données SCI-expanded, cette étude présente une description quantitative du développement de la recherche sur les métalloprotéases matricielles sur une période de 20 ans. De 1986 à 2007, la littérature scientifique en lien avec les MMP s'est accrue d'un facteur 7 (397 articles en 1986-1987 à 2834 en 2006-2007). Durant la période 1986-2007, le nombre de pays participant à la recherche sur les MMP a doublé (33 en 1986-1987 et 67 en 2006-2007), et les États-Unis ont maintenu leur position de leader. Plusieurs pays industrialisés (Japon, Allemagne, Royaume-Uni, Canada et France) ont aussi joué un rôle important, avec quelques pays émergents d'Asie qui se sont joint aux dix pays les plus productifs en 2006-2007 : la Chine (5ième rang), la Corée du Sud (6ième) et Taiwan (10ième). La littérature reliée aux MMP était distribuée à travers un nombre croissant de revues scientifiques (188 en 1986-1987, 527 en 1996-1997 et 913 en 2006-2007), et The Journal of Biological Chemistry est demeurée la plus prolifique durant toute cette période. Le développement de la recherche sur les MMP au cours des deux dernières décennies a aussi été caractérisé par un transfert progressif de l'intérêt de la recherche fondamentale vers la médecine clinique ; la biologie cellulaire et la pharmacologie ont constitué des voies de recherche importantes généralement poursuivies par les chercheurs. Au cours de la période analysée, des revues spécialisées dans la recherche en oncologie ont progressivement intégré le top-8 des revues les plus prolifiques. [ABSTRACT FROM AUTHOR]

Objective. This study traces the evolution of the scientific literature on pain published during the last 30+ years (1976–2007). Methods. Using the Web of Science®, pain-focused journal articles from the Science Citation Index Expanded™ published in 1977, 1987, 1997, and 2007 were retrieved and analyzed. Results. The number of pain-related publications rose from 1,562 articles for 1976–77 to 9,159 PubMed for 2006–2007, with slow growth for the period 1976–1995, and rapid increases from 1995–2007. The analysis of contributing countries showed two major players, the United States and the UK; the doubling of the number of countries involved in pain research from 40 in 1977 to 82 in 2007; and the appearance in 2007 of The Netherlands, Turkey, China, and Brazil among the top-15 most prolific contributors. During the 30-year period, the number of journals publishing pain-related research increased nearly 2.5-fold (363 journals in 1977 vs 972 in 2007), including 14 new, international pain-focused journals since 2000. Additionally, while there were only two pain journals ( Pain and Headache) in 1977, 15 pain-focused journals were indexed in 2007 with the result that 17 of the top-20 pain-focused journals in 2007 did not exist in 1977. Conclusion. The rapid evolution and explosion of pain research in the last 30+ years was reflected in substantial changes in the landscape of the contributing countries and in the scientific journals targeted by pain researchers.

This study assessed the intermix of local citation analysis and survey of journal use and reading patterns for evaluating an academic library's research collection. Journal articles and their cited references from faculties at the University of New South Wales were downloaded from the Web of Science (WoS) and journal impact factors from the Journal Citation Reports. The survey of the University of New South Wales (UNSW) academic staff asked both reader-related and reading-related questions. Both methods showed that academics in medicine published more and had more coauthors per paper than academics in the other faculties; however, when correlated with the number of students and academic staff, science published more and engineering published in higher impact journals. When “recalled” numbers of articles published were compared to “actual” numbers, all faculties over-estimated their productivity by nearly two-fold. The distribution of cited serial references was highly skewed with over half of the titles cited only once. The survey results corresponded with U.S. university surveys with one exception: Engineering academics reported the highest number of article readings and read mostly for research related activities. Citation analysis data showed that the UNSW library provided the majority of journals in which researchers published and cited, mostly in electronic formats. However, the availability of non-journal cited sources was low. The joint methods provided both confirmatory and contradictory results and proved useful in evaluating library research collections.

Objective: To explore journal quality as perceived by clinicians and researchers in clinical neurology. Methods: A survey was conducted from August 2003 to January 2004. Ratings for 41 selected clinical neurology journals were obtained from 254 members of the World Federation of Neurology (1,500 solicited; response rate 17%). Participants provided demographic information and rated each journal on a 5-point Likert scale. Average ratings for all journals were compared with the ISI's journal impact factors. Ratings for each journal were also compared across geographic regions and respondent publication productivity. Results: The top 5 journals were rated much more highly than the others, with mean ratings greater than 4. Mean journal ratings were highly correlated with journal impact factors (r = 0.67). Most of the top 10 journal ratings were consistent across the subgroups of geographic regions and journal paper productivity. However, significant differences among the different geographical regions and respondent productivity groups were also found for a few journals. Conclusions: The results provide valuable insight on how neurological experts perceive journals in clinical neurology. These results will likely aid researchers and clinicians in identifying potentially desirable research outlets and indicate journal status for editors. Likewise, biomedical librarians may use these results for serials collection development. [ABSTRACT FROM AUTHOR]

This study provides an overview of the sleep research literature in medicine and biology through bibliometric analyses of the distribution of journal articles per country, the average journal impact factor of each country, the journal subject category of each article, and the population and gross domestic product of the top-producing countries. The authors of the 2325 articles were from 66 countries – the most prolific being the USA, Germany, Japan, The United Kingdom, France and Canada. This study complements continuing subject reviews on sleep research and offers readers a better understanding of the literature size and research richness in this field. [ABSTRACT FROM AUTHOR]

Findings from informetric research represent an important background resource to add to the mix of information useful for resolving difficult and ongoing problems in specific library environments or information service settings. This paper provides examples of informetric research that can be useful input to decision-making in the field of library management and information service provision. This overview takes four of the challenges that Michael Buckland outlined for library research as a way of guiding the discussion of ways that informetric work can be used to inform library decision-making.' References are made to relevant informetric work undertaken or conducted in Australia, by Australian researchers, or with Australian data. Informetrics includes both quantitative and qualitative methods, which when used in combination can provide a rounded set of findings that has great validity for management, policy and service applications. Quantitative methodologies are generally based on bibliometric techniques, such as mining and analysis of data from various bibliographic and textual databases. Qualitative methods include survey, case study and historical approaches. Used in combination, each set of findings adds richness and other perspectives to an analysis. [ABSTRACT FROM AUTHOR]

Australian library and information studies professional education experienced major changes over the past 15 years or so. There has been a growth in first professional level masters programs. Some schools have been involved in organisational relocation. Program structural changes have aimed to make programs more flexible and appealing to prospective students. These changes have not produced increased enrolments: rather, enrolments have fallen. [ABSTRACT FROM AUTHOR]

The performance of the World Wide Web is evaluated as an information resource in a specific information domain. The theoretical framework underpinning this approach recognises the contribution of information-seeking behaviour from the discipline of information science and models of information systems success from the discipline of information systems in explaining World Wide Web usage as an information resource. A model integrating the construct of uncertainty and the task-technology fit model is presented. A questionnaire-based empirical study is used to test this integrated approach. Our results confirm that richer models representing the broad context of World Wide Web usage are required to evaluate usage of the World Wide Web as an information resource. Usage for travel tasks, uncertainty reduction, the Web as an information resource, and mediation all have a significant impact on users' perception of performance, explaining 46 per cent of the variance.

The article discusses the use of the World Wide Web for international travel by integrating the construct of uncertainty in information seeking and the Task-Technology Fit Model. The author states that the evaluation and measurement of information provision through traditional media has been the domain of information science. Concepts of "information need" and "information seeking behavior" have been seminal in evaluating information services and user behavior when interfacing with traditional media. These two disciplines have now converged through Web technologies that utilize information and communication technologies to meet the information needs of the population at large. Evaluation of Web technologies as an information resource should bring together these two perspectives. In this article a model integrating information systems models of success and information science concepts of information seeking and uncertainty reduction is proposed. Specifically, the concept of "uncertainty" is integrated into the task-technology fit model to evaluate Web usage within the non-work domain of personal travel.

This article investigates the relationship between the journal "impact factor" (IF) and the "immediacy index" (II) in the sciences, as well as the social sciences. It is found that there are highly positive correlations between the IF and the II in most sciences and social sciences disciplines although the correlation strengths vary across disciplines. Moreover, it is found that the II of year Y is also a good predictor for the IF of year Y + 1. These results are strongest for rapidly developing fields, such as biomedicine. Based on the assumption that the citation-age distribution has a Poisson distribution, our empirical data are clarified by a simulation. [ABSTRACT FROM AUTHOR]

Bibliographic databases contain surrogates to a particular subset of the complete set of literature; some databases are very narrow in their scope, while others are multidisciplinary. These databases overlap in their coverage of the literature to a greater or lesser extent. The topic of Fuzzy Set Theory is examined to determine the overlap of coverage in the databases that index this topic. It was found that about 63% of records in the data set are unique to only one database, and the remaining 37% are duplicated in from two to 12 different databases. The overlap distribution is found to conform to a Lotka-type plot. The records with maximum overlap are identified; however, further work is needed to determine the significance of the high level of overlap in these records. The unique records are plotted using a Bradford-type form of data presentation and are found to conform (visually) to a hyperbolic distribution. The extent and causes of intra-database duplication (records duplicated in the one database) are also examined. Finally, the overlap in the top databases in the dataset were examined, and a high correlation was found between overlapping records, and overlapping DIALOG OneSearch categories.

Abstract Background: In 2000, the Australian and New Zealand Journal of Ophthalmology (ANZJO ) changed title to Clinical and Experimental Ophthalmology. At this time, a review of Australia's contributions to the literature over the previous 21 years appears timely. Bibliometric indicators are used extensively to assess research performance as they offer views of a field that might not otherwise be apparent. The aim of this study was to explore publication output data to construct a picture of ophthalmology that may be of benefit to researchers and ophthalmologists. Methods: Science Citation Index and Social Sciences Citation Index databases were used to collate data on ophthal­mology research literature from 1980 to 2000. Subsequent analysis particularly focused on Australia's contribution to this literature, including publication frequency vis-à-vis the world, collaboration, and the journals in which Australian researchers frequently publish. These data were also compared with other countries of similar scientific stature or language. Results: Since 1980, Australia has ranked in the top 10 nations contributing to world ophthalmology research. Its contribution was close to world average in the 1980s, but increasing numbers of researchers and papers show Australia exceeding the world average during the 1990s. Most ophthalmology research collaboration by Australians is within Australia. Although fewer in number, collaborative papers with overseas researchers include 28 other countries. Data on the journals in which Australians publish show that Australian researchers continue to exhibit a preference for publication in their own regional journals. Conclusions: This paper, one of a series on the literature of the vision sciences, provides some initial benchmarks on Australia's standing and contribution to the field of ophthalmology research.

Indicators of science and technology (S&T) activity often disadvantage developing countries, due, in part, to incomplete compilation of statistics or to the examination of indicators in isolation. Among the major indicators of S&T activity are research and development (R&D) expenditures and their relationship to gross domestic product, numbers of personnel involved in S&T research, scientific publication output and rankings by scientific discipline, and numbers of patents registered in the international patent systems. A 'composite index of S&T capacity' developed by researchers at the Rand Corporation is described and applied comparatively. We have compiled data on Iranian S&T activity under the following headings: R&D expenditure, population and educational profile, academic personnel, R&D personnel. A scientometric analysis of Iranian S&T publications using the Science Citation Index is presented, and possible shortcomings of this approach discussed. All findings are reported, analysed, and discussed with reference to the various compilations of S&T indicators and to our earlier studies on Iranian scientific publications. In particular we analyse annual distributions of world and Iranian S&T publications, international collaboration of Iranian scientists, journals where Iranian scientists publish and journals they cite, the most productive Iranian scientists and the extent of their influence nationally and internationally, and S&T subject areas in which Iranian scientists excel. We conclude with comments and suggestions for the continued development of Iran's S&T capacity. [ABSTRACT FROM AUTHOR]

This paper reports the findings of an exploratory study of position vacant announcements appropriate for library and information studies (LIS) graduates appearing in the Sydney Morning Herald over a four week period in each of the following years: 2004, 1994, 1984 and 1974. The period studied witnessed change-demanding developments in information technologies as well as changes in workplace conditions and client expectations. The study collected data on the demands of employers as expressed through job advertisements that included data on work status (full-time, part-time, contract, casual), qualifications and the experience required of the information professional during the periods selected. To investigate similarities and differences between periods a content analysis and co-word analysis of the job advertisement was undertaken. The advertisements indicated a movement from simple advertisements in 1974 inviting applications for reference or technical services librarians, to complex and specialised positions being advertised in 2004 where the most called for attributes were interpersonal skills and behavioural characteristics.

Bibliometric measures for evaluating research units in the book-oriented humanities and social sciences are underdeveloped relative to those available for journal-oriented science and technology. We therefore present a new measure designed for book-oriented fields: the “libcitation count.” This is a count of the libraries holding a given book, as reported in a national or international union catalog. As librarians decide what to acquire for the audiences they serve, they jointly constitute an instrument for gauging the cultural impact of books. Their decisions are informed by knowledge not only of audiences but also of the book world (e.g., the reputations of authors and the prestige of publishers). From libcitation counts, measures can be derived for comparing research units. Here, we imagine a match-up between the departments of history, philosophy, and political science at the University of New South Wales and the University of Sydney in Australia. We chose the 12 books from each department that had the highest libcitation counts in the Libraries Australia union catalog during 2000 to 2006. We present each book's raw libcitation count, its rank within its Library of Congress (LC) class, and its LC-class normalized libcitation score. The latter is patterned on the item-oriented field normalized citation score used in evaluative bibliometrics. Summary statistics based on these measures allow the departments to be compared for cultural impact. Our work has implications for programs such as Excellence in Research for Australia and the Research Assessment Exercise in the United Kingdom. It also has implications for data mining in OCLC's WorldCat. [ABSTRACT FROM AUTHOR]
