In this study, we examine the authorship trend and collaboration pattern in Marine Sciences literature. For this purpose, the required data has been collected from the Indian Journal of Marine Sciences published from 2001 to 2010. Scientometric tools such as, collaboration index, collaboration co-efficient and dominance factor have been used. Applicability of Lotka’s law has been tested. Further, level of collaboration has been observed among the authors. The study reveals that the coauthored papers are dominated and the author productivity follows the Lotka’s law. Average collaboration rate (0.57) is better collaboration and mean number of authors per joint authored paper is 3.4.

Authorship Trends and Collaboration Pattern in the Marine Sciences Literature : A Scientometric Study

Concerns have been raised of a potential connection between excessive online activity outside the academic realm and increased levels of psychological distress in young people. Young Minds Matter: the second Australian Child and Adolescent Survey of Mental Health and Wellbeing provides estimates of the prevalence of online activity and allows an exploration of associations between this activity, a range of mental disorders, socio-demographic characteristics and risk taking behaviour. Based on a randomized nationally representative sample, a household survey of mental health and wellbeing (Young Minds Matter) was conducted in 2013-14. Interviews were conducted with 6,310 parents and carers of 4–17 year-olds (55 % response rate), together with self-report questionnaires completed by 2,967 11–17 year-olds in these households (89 % response rate). The survey identified a range of mental disorders and emotional problems using a variety of diagnostic tools, with the self-report including questions about use of the Internet and electronic games. Five behaviours were measured related to this activity, with ‘problem behaviour’ being defined as exhibiting at least four out of five behaviours. Levels of Internet use (98.9 %, CI 98.5–99.3 %) and electronic gaming (85.3 %, CI 83.9–86.6 %) were high, and 3.9 % (CI 3.2–4.6 %) of young people reported problem behaviour. The proportion of girls with very high levels of psychological distress and problem behaviour (41.8 %,CI 28.8–54.9 %) was twice that for boys (19.4 %, CI 7.7–31.1 %). Those engaging with a range of risk factors reported higher prevalence of problem behaviour than others. Youth who suffered from emotional problems or high levels of psychological distress spent the most time online or playing games. Multivariate analysis showed associations with problem behaviour and having attempted suicide, experiencing high to very high levels of psychological distress, using alcohol, and living in a poorly functioning family. It was not possible to determine the direction of the associations. There are links between problem behaviours associated with Internet use and electronic gaming, and mental disorders and risk-taking behaviour in young people. Further studies are required to determine whether these are precursors or sequelae.

Conventional stereoscopic three-dimensional displays suffer from vergence- accommodation conflict because the stimulus to accommodation is fixed by the display panel and viewing optics, but that to vergence changes with image contents. With the recent rapid development of head-mounted displays, several methods have been proposed to offer the accommodation cues, among which multifocal display technology is an effective and practical solution. The first two decades of this century has witnessed the fast growth of multifocal displays from basic concept to mature implementations. This review systematically presents the state-of-the-art multifocal display design and development. Firstly, a comprehensive classification of numerous potential optical architectures to provide the multiplanar functionality is introduced, based on how the information is multiplexed and how the focal planes are generated. Next, the strengths and obstacles of reported or potential designs in each category are analyzed and compared with each other. In addition to enabling optics, the image rendering approaches for the multifocal planes are also described. This review presents a sufficient collection of past designs and is expected to offer a roadmap for future research and development of multifocal displays.

Causes and Effects of Forest Fires in Tropical Rainforests: A Bibliometric Approach:

Abstract This study marks the end of the UN Decade of Education for Sustainable Development that coincides with the 10th anniversary of the Baltic and Black Sea Circle Consortium on Educational Research (BBCC), and aims to analyse the research output performance of BBCC members and other scholars published in the Journal of Teacher Education for Sustainability (JTEFS) during this last decade. Using the methodology of bibliometric study and literature review, the authors describe the main bibliographic indicators of JTEFS and provide a qualitative and quantitative analysis of the research paradigms and their developmental changes in the papers published by JTEFS (2005ñ2014). The results of the study show that in general the journal has evolved in line with the advanced trends in educational research, research in teacher education, research in sustainability education and sustainability studies in higher education. The analysis of published papers indicates both the progress and issues of research in teacher education for sustainability. The authors conclude with some visionary insights into the further development of JTEFS and this research field in general.

This study aims at analysing the research output performance of social scientists on social science subjects. The analysis cover mainly the number of articles, authorship pattern, subject wise distribution of articles, average number of references per articles, forms of documents cited, year wise distribution of cited journals etc. and Eales in 1917, while Hulme used the term 'statistal Bibliography' in 1923. In 1948, the great Library Scientist, S.R. Ranganathan, coined the term "Librametry", which historically appeared first and perhaps seemed proper to streamline the services of librarianship. The term 'Bibliometrics' is just analogous to Ranganathan's Librametrics', the Russian concept of Scientometrics', FID's 'Informetrics' and to some other well established sub-disciplines like 'Econometrics', 'Psycho- metrics', 'Sociometrics', 'Biometrics', 'Techno- metrics', 'Chemometrics', 'Climetrics', where mathematical and statistical calculus have been systematically applied to study and solve problems in their respective fields. Now-a- days, the term 'Scientometrics' is used for the application of quantitative methods to the history of science and obviously overlaps with bibliometrics to a considerable extent. Bibliometrics is a type of research method used in Library and information sciences. It is an emerging area of research in the LIS field. The quantitative analysis and statistics to describe patterns of publication within a given field of body of literature are utilized. Researchers use bibliometric methods of evaluation to determine the influence of a single author or to describe the relationship between two ore more authors or works. Bibliometric studies can be used to study regional patterns of research, the extent of co- operation between research groups and national research profiles. The main derivatives of biblio- metrics are: publication counts, citation counts, co-citation analysis, co-word analysis, scientific 'mapping' and citations in patents. The word 'bibliometric' has been derived from the Latin and

Journal of Social Sciences: A Bibliometric Study

This paper presents a bibliometric analysis of the journal titled “Library Herald ” for the period between 2006 to 2010. The analysis cover mainly the number of articles, authorship pattern, subject wise distribution of articles, average number of references per articles, forms of documents cited, year wise distribution of cited journals etc. All the studies point towards the merits and weakness of the journal which will be helpful for its further development. The result showed that out of 138 articles single author contributed 72 (52.17%) articles while the rest 66 (47.83%) articles were contributed by joint authors. Study reveals that most of the contributions are from India with 89.85 % and the rest 10.15 % only from foreign sources.

Library herald journal: a bibliometric study

Introduction Bibliometrics is a research method used in library and information science. It is a quantitative study of various aspects of literature on a topic and is used to identify the pattern of publication, authorship, and secondary journal coverage to gain insight into the dynamics of growth of knowledge in the areas under consideration. This can lead to better organization of information resources, which is essential for effective and efficient use. Bibliometrics has attained sophistication and complexity with a national, international, and interdisciplinary character. The term "bibliometrics" was coined by Pritchard in 1969. A pioneering example of a bibliometric study was statistical analysis of the literature of comparative anatomy from 1543 to 1860, done by counting book and journal titles, and grouping them by countries of origin and periods. In 1923, a study was conducted by Hulme, entitled "Statistical Analysis of the History of Science". His analysis was based on the entries in the English International Catalogue of Scientific Literature. A third study was the work of Gross and Gross reported in 1927. They counted and analyzed the citations in articles from the Journal of the American Chemical Society, and produced a list of journals deemed important to chemical education. Another prominent work was Bradford's 1934 article on the distribution of literature in lubrication research. It is an important part of the theoretical foundation of bibliometrics, "Bradford's Law of Scattering." In 1948, the great library scientist, S.R. Ranganathan, coined the term "librametry", which historically appeared first and was intended to streamline the services of librarianship. Bibliometrics is analogous to Ranganathan's librametrics, the Russian concept scientometrics, boometrics, and subdisciplines like econometrics, psychometrics, sociometrics, biometrics, technometrics, chemometrics, and climetrics, where mathematics and statistics are applied to study and solve problems in their respective fields. Scientometrics is now used for the application of quantitative methods to the history of science and overlaps with bibliometrics to a considerable extent. Need for the Study Periodicals are the indicators of literature growth in any field of knowledge. They emerge as the main channel for transmitting knowledge. Due to the escalating cost of the periodicals and lack of adequate library budgets, the selection of any particular journal for a library should be done carefully. Library authorities are forced to reduce the number of journal subscriptions. Bibliometric analysis has many applications in library and information science in identifying research trends, core journals, etc., and thereby framing subscription policies for tomorrow. These studies will be helpful for librarians in collection development. Library Philosophy and Practice Library Philosophy and Practice (LPP) describes itself as "a peer-reviewed electronic journal that publishes articles exploring the connection between library practice and the philosophy and theory behind it. These include explorations of current, past, and emerging theories of librarianship and library practice, as well as reports of successful, innovative, or experimental library procedures, methods, or projects in all areas of librarianship, set in the context of applied research." (http://unllib.unl.edu/LPP It was founded in 1998 and was published twice a year until 2007, when it began to publish a continuous annual volume. Objectives of the Study The present study has been undertaken with the objective of analyzing the following aspects. Analysis of articles * to make an analysis of articles published in LPP from 2005-2009. * to identify the number of contributions published during the period of study. * to determine the year-wise distribution of articles. * to study the authorship pattern * to find out the ranking of leading contributors * to study the subject coverage of articles. …

Bibliometric Analysis of the Journal Library Philosophy and Practice from 2005-2009

Sources of information available via the Internet are increasing exponentially, leading to steady increase in the use of Internet for education and research. Since past few years, free online information sources like ejournals, e-books, e-databases have increased considerably. Earlier, information and knowledge were passed by word of mouth or through manuscripts, and communication was a slow process. Today, it is passed from one individual to an infinite number of other users through a number of media and formats which makes rapid and widespread dissemination of information possible. This paper discusses utilisation of digital resources by faculty and research scholars of Manonmaniam Sundaranar University, Tirunelveli. Results show that 67.14 per cent of the faculty is familiar with the use of digital resources, and majority of these members are using digital resources for research purpose. Study also reveals that majority of the faculty members are learning the required skills for the usage of digital resources through self-study.
