The present study investigates authorship trends and productivity among Library and Information Science (LIS) professionals who contributed journal articles in the selected 12 peer reviewed LIS journals of India, US and UK. For the purpose of the study four periodicals from each country are chosen during the period 2007 to 2017. The results analyzed proved that journal wise author distribution is highest in the published literature of UK with (3546) authors followed by India with (3162) and US (2420) authors. The obtained values of χ²= 66.331, ρ=0.05 found that there is an association between type of authorship and country. As India and UK accounted for more number of collaborative works while US has large number of solo article contributions. The data analyzed shows preference towards collaborative research in all the three countries with little variations. Lotka's law have been applied and tested using Pao's method and verified through Kolmgorov-Smirnov (KS) test. The application of Lotka's law when applied individually on author's data set of published literature of India with Dmax value=0.0238 and critical value=0.046, proves that observed authorship data holds good for Lotka's law in the authors' data. But with Dmax value=0.1362 and CV=0.04 in the author distribution of US and D max value=0.2520 and CV=0.04 of UK, does not support lotka's law. Overall the results of the K-S tests proved that author productivity distribution does not fits Lotka's law in the subject of library and information science in scholarly research output in Library and information science published journal literature of US and UK.

Dyslexia, or a reading disability, occurs when an individual has significant difficulty with speed and accuracy of word decoding. Comprehension of text and spelling are also affected. The diagnosis of dyslexia involves the use of reading tests, but the continuum of reading performance means that any cut off point is arbitrary. The IQ score does not play a role in the diagnosis of dyslexia. The cognitive difficulties of dyslexics include problems with speech perception, recognizing and manipulating the basic sounds in a language, language memory, and learning the sounds of letters. Dyslexia is a neurological condition with a genetic basis. There are abnormalities in the brains of dyslexic individuals. There are also differences in the electrophysiological and structural characteristics of the brains of dyslexics. Physicians play a particularly important role in recognizing children who are at risk for dyslexia and helping their parents obtain the proper assessment. The fundamental aim of this study was, to analyze the application of Lotka's law to the research publication, in the field of Dyslexia. The data related to Dyslexia were extracted from web of science database, which is a scientific, citation and indexing service, maintained by Clarivate Analytics. A total of 5182 research publications were published by the researchers, in the field of Dyslexia. The study found out that, the Lotka's inverse square law is not fit for this data. The study also analyzed the authorship pattern, Collaborative Index (CI), Degree of Collaboration (DC), Co-authorship Index (CAI), Collaborative Co-efficient (CC), Modified Collaborative Co-efficient (MCC), Lotka's Exponent value, Kolmogorov-Smirnov Test (K-S Test), Relative Growth Rate and Doubling Time.

Lotka's Law describes the frequency of publications by authors in a given subject/discipline. In the present study, an attempt has been made to study the suitability of the Lotka's Law to the publications of a Higher Educational institution of a region consisting of academic authors and researchers in various disciplines. Annamalai University has been ranked 20th in the state level and 56th at National level by MHRD. Annamalai University is renowned for its research output performance and has been funded for many major, minor and DST research projects. It has a large network and linkages to academia, R&D organisations and industries. It covers almost all the subjects with 10 Faculties and 49 departments of study. Examines the applicability of Lotka's Law as a general inverse power (a # 2) and as an inverse square power relationship (a = 2) to the distribution of the research productivity Annamalai University, South India. Two datasets of the research papers (936 and 3370) contributed by Annamalai University academic authors and researchers during the period of 2000-2006 and 2011-2017 were collected from Web of Science Database. A K-S Test was applied to measure the degree of agreement between the distribution of the observed set of data against the inverse general power relationship and the theoretical value of a=2. It was found that the inverse square law of Lotka does not show conformity as such. [ABSTRACT FROM AUTHOR]

This paper analyses various bibliometric dimensions of the journal literature such as authors' productivity, geographical distribution, citation pattern, institution-wise distribution of articles, discipline-wise distributions of articles, productive institutions, Productivity Index (PI), Activity Index (AI), Domestic Collaborative Index (DCI) and International Collaborative Index (ICI) etc. It also explores the applicability of Lotka's Inverse Square Law and Zipf's Law to examine the observed rank - frequency pattern of Keywords and Subject Terms of Information Systems (IS) literature. To illustrate these bibliometric indicators pertinent information on the field of Information Systems (IS) collected from EBSCO database for the International Journal of Cooperative Information Systems (IJCIS). Results indicated that a high level of collaboration exists among the authors, USA occupies the dominant position in terms of high productive authors, institutions and tops the list with highest number of domestic collaboration. Authors' productivity confirms to Lotka's law and the Frequency distribution of both Subject Terms and Keywords in IJCIS journal literature follow Zipf's distribution. [ABSTRACT FROM AUTHOR]

The paper reveals the scientific productivity pattern of authors in the field of Astronomy & Astrophysics research in India and applicability of Lotka's law in the literature of Astronomy & Astrophysics for the given data set. Data was retrieved from WoS database for this study, a total of 6,363 papers has been published by 2,719 authors during 2013-2017 in straight count of the authorship. Examining the Lotka's Inverse square (n=2) method as well as general power method (n≠2), (calculating the value of 'n' with observed data) was used to test the applicability of Lotka's law. Goodness of fit test - Chi-Square test and Kolmogorov-Smirnov (KS) test was also used to measure the viability of Lotka's law in the field of Astronomy & Astrophysics research in India. The productivity distribution didn't fit when Lotka's law was applied in generalized form as well as in its original form on the data set. This confirms that Lotka's law doesn't fit to the literature of Astronomy & Astrophysics. [ABSTRACT FROM AUTHOR]

An earthworm is a soil living organism and seems in soil. It helps to make the soil more nutritious and used as an organic fertilizer. So earthworms are called as best partner for the soil and the farmer. This research is concentrated on earthworm analysis. The records are collected from web of science database for the period of 2007 - 2016. Total number of publications collected for this study was 3939. Composting with worms is called as vermicomposting. It is a good way to dispose all organic wastes, such as vegetable and fruit peelings. By the vermicomposting, the wastes are converted into nutritious by earthworm. In every home, wastes are converted into this vermicomposting the home and the city are clean. And it maintains the country very clean and protects the surrounding clean. And it may use for the terrace garden and home garden plants. This compost is a green way for organic vegetables, fruits, flowers and soil. Most of the agricultural universities, give the awareness and training program of vermicomposting to the farmers. And now- a-days the farming based on vermicomposting has been developing. [ABSTRACT FROM AUTHOR]

The study is based on the articles published in the open access journal, Advances in Anthropology during the year 2013-2014 covering 59 articles in 8 issues having 1750 citations. Data has been collected from Advances in Anthropology from the Directory of Open Access Journals. Data has been analyzed by using excel sheet by year, types of document, trend of research, author productivity, journal productivity etc. The citation study has been carried out to find out the various sources of literature used by the researchers in the field of Anthropology. A rank list of journals is also prepared to find out the core journals based on the citation frequencies. Applicability of Bradford's Law of scattering is tested here to identify the core journals in the field of anthropology. Lotka's Law of Author Productivity is also tested to find out the most active authors in anthropology. Authorship Pattern has been studied to know whether collaborative or individual research is mostly done in the field of Anthropology. In this way trend of research, growth of research, type of documents, etc are analyzed. It has been observed that the articles published in the year 2007 have been cited maximum number of times i.e. 140 times and the journal Nature is the most popular journal for the anthropologists. Bradford's Law of Journal Productivity is applicable but Lotka's Law of Author's Productivity does not follow here. From the study it has also been identified that individual research is more prominent than collaborative research and Physical Anthropology is the most promising field of research.
