Lotka’s law and author productivity pattern of research in law discipline

PurposeThis study aims to analyze the productivity patterns of authors using law literature indexed in Directory of Open Access Journals (DOAJ) from 2016 to 2020 based on Lotka’s law. Lotka’s law of scientific productivity provides a platform for studying the variation between the actual and expected authors’ productivity patterns in a subject area over a specified period.Design/methodology/approachThis study covers 3,334 open access journal articles in law subject. The law journals are subdivided into two basic divisions, namely, public law and private law. This paper focuses on the journal-wise distribution of publications, subject-wise distribution of publications, annual growth rate (AGR) as well as compound AGR and applicability of Lotka’s law in both public and private law by applying the least square method followed by Pao and doing the K-S goodness-of-fit test. Student’s t-test and chi-square test have been applied to verify the significant difference between the public law and the private law literature.FindingsThere is no significant difference between the public law and private law publications on their publications per issue. The chi-square test showed that there is no significant difference between the year-wise publications in public law and private law. The authorship productivity in public law differs from the distribution of Lotka’s inverse square law, whereas it follows Lotka’s law in the case of private law.Research limitations/implicationsThis study is based on the articles published in open access English language journals which are indexed in the DOAJ.Originality/valueThis study will be useful to know the authorship productivity pattern of law literature for both public and private law individually.

Author productivity pattern and applicability of Lotka’s inverse square law: a bibliometric appraisal of selected LIS open access journals

Purpose The purpose of this paper is to know whether the authors’ productivity pattern of library and information science (LIS) open access journals adheres to Lotka’s inverse square law of scientific productivity. Since the law was introduced, it has been tested in various fields of knowledge, and results have varied. This study has closely followed Lotka’s inverse square law in the field of LIS open access journals to find a factual result and set a baseline for future studies on author productivity of LIS open access journals. Design/methodology/approach The publication data of selected ten LIS open access journals pertain to authorship, citations were downloaded from the Scopus database and analysed using bibliometric indicators like authorship pattern, collaborative index (CI), degree of collaboration (DC), collaborative coefficient (CC) and citation counts. This study has applied Lotka’s inverse square law to assess authors’ productivity pattern of LIS open access journals and further Kolmogorov-Smirnov (K-S) goodness-of-fit test applied for testing of observed and expected author productivity data. Findings Inferences were drawn for the set objectives on authorship pattern, collaboration trend and authors’ productivity pattern of LIS open access journals covered in this study. The single authorship pattern is dominant in LIS open access journals covered in this study. The CI, DC and CC are found to be 1.95, 0.47 and 0.29, respectively. The expected values as per Lotka’s law (n = −2) significantly vary from the observed values as per the chi-square test and K-S goodness-of-fit test. Hence, this study does not adhere to Lotka’s inverse square law of scientific productivity. Practical implications Researchers may find an idea about the authors’ productivity patterns of LIS open access journals. This study has used the K-S goodness-of-fit test and the chi-square test to validate the authors’ productivity data. The inferences found out from this study will be a baseline for future research on author productivity of LIS open access journals. Originality/value This study is significant from the viewpoint of the growing research on open access journals in the field of LIS and to identify the authorship pattern, collaboration trend and author productivity pattern of such journals.

Bibliometric analysis of indian pulp and paper technical association journal (2005-2019)

IPPTA (Indian Pulp and Paper Technical Association) Journal is a well-known journal in the Indian pulp and paper fraternity with a publishing history of fifty-five years. This study presents a bibliometric overview of articles published in the IPPTA Journal during 2005-2019. This is the first bibliometric study of a journal completely dedicated to pulp and paper research. The bibliometric analysis included analysis of article distribution, subject classification, authorship pattern, author productivity and collaboration, geographical distribution, references, keywords, prominent institutions, and citations. It also accounts for Lotka's law of scientific productivity, relative growth rate, doubling time, frequently contributing authors and top-cited articles. It was found that during this period 830 articles were published in IPPTA Journal. The average number of articles published per year in the journal is ~56. A total of 2361 authors from 27 countries and 339 unique institutes were identified in these articles. These articles contained 1009 unique keywords, used 5968 references, and received 561 citations. 74.10% of articles were contributed by joint authors. Out of the total 5968 references cited in this journal during the period of study, 48.51% were sourced from journal articles. The overall degree of collaboration, modified collaboration coefficient, average author per article, productivity per article, and collaboration index were calculated to be 0.7410, 0.5030, 2.8446, 0.3515, and 3.8390, respectively. Nonetheless, highlighting various interesting features, this analysis also detected certain inadequacies that need to be resolved for further improvement of this journal.

Indian Doctoral Research in the Field of Library and Information Science: An Empirical Analysis

In this paper, we analyzed systematically the doctoral research works produced by Indian Universities in the discipline of Library and Information Science (LIS). This study aims to find out the developmental pattern, current trends, popular focused areas, most productivity universities, and supervisors, as well as language and gender-wise productivity of LIS theses. Based on two Indian data sources a database was developed on LIS doctoral research and inferences were drawn as per the research questions formulated. It was observed that altogether 957 doctoral theses have been guided by 382 supervisors from 105 universities in India. Lotka’s law of scientific productivity was applied for the first of it’s kind to the ‘guide-ship pattern of doctoral works’ and found validated. Five broad areas of research are found to be the most focused themes of Indian LIS research. This paper highlights the evolution and pattern of LIS research to identify the areas that have influenced the scholars most and to know the direction of research.

Multifocal contact lenses: A bibliometric study

PurposeTo analyze the state of scientific publications in multifocal contact lenses field through a bibliometric study. MethodsThe database used to carry out the study was SCOPUS and contained the descriptors “multifocal contact lens”, “bifocal contact lenses”, “progressive contact lenses” and “presbyopia contact lenses”, limited to the fields of title, keywords and abstract. The indicators applied in this research were: doubling time and annual growth rate, Price’s transience index, Lotka’s law of scientific productivity, and Bradford’s zones. ResultsA total of 346 articles were published between 1960 and 2019. The growth in the number of publications matches the exponential adjustment slightly better (R = 0.53). The duplication time was 13.2 years. The productivity level is focused on articles with an average number of authors of just 2.06 per article. The Bradford core was formed by two journals, Optometry and Vision Science and Eye and Contact Lens. ConclusionsResearch on multifocal contact lenses has exponential growth, without evidence of having reached a saturation point. The main countries in scientific production in this field are the United States and Australia.

Authorship trend and content analysis

PurposeThe purpose of this paper is to examine the classic characteristics of highly cited articles (HCAs) of top-ranked library and information science (LIS) journals and get acquainted with the high-quality works in specific areas of LIS for distinguishing what gets cited and who the prolific authors are.Design/methodology/approachThe HCAs published across the top four LIS journals were downloaded, coded and a database was developed with basic metadata elements for analysis using bibliometric indicators. Lotka’s Inverse Square Law of Scientific Productivity was applied to assess the author’s productivity of HCA. The content analysis method was also used to find out the emerging areas of research that have sought high citations.FindingsInferences were drawn for the proposed five number of research questions pertaining to individual productivity, collaboration patterns country and institutional productivity, impactful areas of research. The Netherland found to be the potential player among all the affiliating countries of authors and Loet Leydesdorff tops the list among the prolific authors. It is observed that Lotka’s Classical Law also fits the HCA data set in LIS. “Research impact measurement and research collaboration,” “Social networking” and “Research metrics and citation-based studies” are found to be the emerging areas of LIS research.Practical implicationsResearchers may find a way what gets cited in specific areas of LIS literature and why along with who are the prolific authors.Originality/valueThis study is important from the perspective of the growing research field of the LIS discipline to identify the papers that have influenced others papers as per citation count, spot the active and more impactful topics in LIS research.

Mapping of Scholarly Communication in Publications of the Astronomical Society of Australia, Publications of the Astronomical Society of Japan, and Publications of the Astronomical Society of the Pacific: A Bibliometric Approach

ABSTRACTIn this study, three journals in the field of astronomy and astrophysics were selected for mapping scholarly communication by using bibliometric methods. Moreover, a brief review of bibliometric studies in the field of astronomy and astrophysics was conducted. The annual publication distribution and authorship pattern of articles in the three journals were analyzed. All three journals published more multiauthored papers. Author productivity indexes, such as the average number of authors per paper and productivity per author were calculated. Lotka’s law of scientific productivity and goodness-of-fit tests were applied; the results revealed that the data set in this study did not conform to Lotka’s law. The h-, g-, and i10-indexes for each journal were calculated. Regarding the geospatial distribution of articles, the authors from the journals’ source country contributed more articles. In this paper, highly contributing institutions and authors are presented. A list of highly cited articles and journals is also presented. The author-given keywords were analyzed.

Lotka's inverse square law of scientific productivity: Its methods and statistics

This brief communication analyzes the statistics and methods Lotka used to derive his inverse square law of scientific productivity from the standpoint of modern theory. It finds that he violated the norms of this theory by extremely truncating his data on the right. It also proves that Lotka himself played an important role in establishing the commonly used method of identifying power‐law behavior by the R2 fit to a regression line on a log‐log plot that modern theory considers unreliable by basing the derivation of his law on this very method.

Lotka’s Law and productivity patterns of authors in biomedical science in Nigeria on HIV/AIDS

This study aims to analyze the productivity patterns of authors in Nigeria using publications indexed in Medline from 2008 to 2012 based on Lotka’s Law. Lotka’s Law of scientific productivity provides a platform for studying inequality in authors’ productivity patterns in a given field and over a specified period.,This study covers all the journal articles on HIV/AIDS pandemic in Nigeria over a period of five years (2008-2012) in Medline, of which 512 articles were reported to have been published during this period. In this paper, 306 articles that had HIV/AIDS in the title, published in 20 journals, and articles that had HIV/AIDS as author keywords were analyzed. Because no local database that indexed biomedical literature from Nigeria was available, Medline was used, which is not only a robust and flexible database that includes articles from Nigeria but is also the largest medical database that indexes over six-and-a-half million articles from 3,400 biomedical journals.,While HIV/AIDS can be considered a global pandemic, Nigeria has the second highest number of new infections reported each year, and an estimated 3.7 per cent of the population is living with the dreaded disease. This study presents a general picture of the distribution of papers as single-author papers, multiple-author papers and the measures of co-authorship. The findings of the study reveal that in the productivity distribution for authors on the subject of HIV/AIDS, only co-authors and non-collaborative authors’ categories fit in the Lotka’s Law, whereas all-authors and first-author categories differ from the distribution of Lotka’s inverse square law.,The empirical evidence used in this paper was based on only articles of HIV/AIDS pandemic in Nigeria that had HIV/AIDS the title. Therefore, the findings of this study might not be the generalized to other biomedical research studies.,The originality of this paper lies in the fact that the productivity pattern of each of the different author categories on the subject of HIV/AIDS is a first of its kind in the Nigerian context.

Bibliometric Portrait of SRELS Journal of Information Management for the Period 2004-2013

(ProQuest: ... denotes formulae omitted.)1. Introduction:Journals are no doubt the most preferred source of information in any field of research due to the nascent information that they carry and faster delivery of research output. But the increasing subscription rates and budget constraints forcing libraries to select and subscribe only the popular journals from the huge number of journals published in different subject fields. Bibliometrics and citation analysis have emerged as the important tools for selection of popular journals in any area of research or subject. As Zafrunnisha (2012) explains, bibliometric techniques are being used for a variety of purposes such as determination of various scientific indicators, evaluation of scientific output, selection of journals for libraries and even forecasting the potential of a particular field. Anyi et al (2009) are of the opinion that bibliometric analysis of single journal creates the portrait of that journal and indicates the quality, maturity and productivity of the journal in any field, in a country or region. It also informs us about the research orientation that it supports to disseminate and its influence on author's choice as a channel to communicate or retrieve information for their research needs. Taking these advantages of presenting bibliometric portrait of journals, Journal of Information is selected for this study. Journal of Information has emerged as one of the highly regarded journal in the field of library and information science in India. In this study an attempt is made to examine the characteristics and present the bibliometric portrait of Journal of Information Management.2. Source Journal:Sarada Ranganathan Endowment for Science has been publishing the quarterly journal 'Library Science with a slant to Documentation' since 1964. It was founded by Dr. S. R. Ranganathan. The title of the journal was changed to Library Science with a slant to Documentation and Information Studies from Vol.25 in 1988 and to SRELS Journal of Information Management from Vol.37 (2000). The journal has been publishing scholarly articles and articles of practical use in the fields of library and information science and services. Journal of Information is published bi-monthly (6 issues per year) since from 2010. Journal has well defined guidelines for authors to submit articles and is peer reviewed by the board of editors. Beginning 2014, the journal is published by Informatics Publishing Limited, Bangalore. From 2015 onwards, manuscripts have to be submitted online and the entire review process will be electronic.3. Objectives of the Study:The objectives of the study are as follows:* To map year-wise distribution of articles* To find the average length of articles* To examine the authorship pattern of the contributions* To study author productivity* To study the range and percentage of references per article* To study different types of resources used and number of citations appended* To study different collaboration measures* To identify and prepare ranked list of authors and journals* To identify and prepare geographical list of contributions and State-wise list of Indian contributions* To study Lotka's law of scientific productivity* To study Bradford's law of scattering4. Methodology:The data required for the study was collected from both print and electronic version of the journal for the period 2004-2013. The references appended to each article were carefully scanned and tabulated in respective tables using Microsoft Excel. The details regarding number of articles published, author names and affiliations are recorded for each article. Citation analysis technique and required bibliometric measures are applied.5. Analysis of Data:Following section discusses the analysis of the data collected and presented under different table headings as per the objectives of the study. …

The Scholarly Status of Blacks in the Economics Profession: Have the National Economic Association and the Review of Black Political Economy Mattered?

This paper considers whether the National Economic Association and its journal the Review of Black Political Economy have enhanced the scholarly status of black economists. A bibliometric analysis reveals that while the typical black economist has never published in the Review of Black Political Economy, the share of black economists publishing in the Review of Black Economy approximates the share of all articles published on the economic and political economy of race by black economists, and the share of articles published in the Review of Black Political Economy by black economists appears higher than typical journals in economics–-particularly for black economists employed at Historically Black Colleges and Universities. We also find that similar to other economics journals non-black economists dominate the share of published articles, and publications in the Review of Black Political Economy appear to be consistent with Lotka's Law of scientific productivity suggesting that the journal is a standard outlet for research no different from any other science journal. Our results imply a plausible counterfactual that if the National Economic Association and Review of Black Political Economy did not exist, the scholarly status of blacks in the economics profession would have been lower than currently observed.

Visibility of african scholars in the literature of bibliometrics

This paper discusses the visibility of African scholars in the literature of Bibliometrics, as it appears in the Library and Information Science Abstract (LISA) from 1982-2010. Analysis was conducted on a list of 75 papers generated from the Abstract. The year-wise growth of the literature shows that single authorship dominates the literature, scoring 52% and the average number of publication per year was found to be 2.7. On the productivity of authors, Lotka’s formulation of inverse square law of scientific productivity was applied and found to be in harmony with the literature. Bradford-zipf Law for distribution of papers was also applied and found to be in conformity with the literature of Bibliometrics. Prolific authors were found to be 6 in number and their contributions falls between 3-16 papers within the 28 years period of the study. English language was found to be the dominant language with 91.3% score, and then followed by French with 8.7% score.

Nutrition sciences in Spain in the second half of the twentieth century: a descriptive bibliometric study of the journal Anales de Bromatologia (1949-1993)

To analyse the institutionalisation of nutrition sciences in Spain in the second half of the twentieth century, and evaluate the activities of the journal Anales de Bromatología. Descriptive bibliometric study of the original articles. Full names of the authors and the complete article title were recorded. Using key words, each article was assigned by consensus of the researchers to a single main subject in accordance with the thirteen subject areas addressed by the Spanish Society of Bromatology in its meetings. An analysis was conducted of the distribution and trends of general productivity indicators and their characteristics. A total of 917 original articles were published, with a mean of 20.8 papers/year. The subjects for which the highest percentage of articles was recorded were foreign substances in foods, foods of plant origin and nutrition. A total of 874 authors contributed, with a collaboration rate of 2.43 and a transience rate of 70.1%. Distribution of the number of authors per article was close to that indicated by Lotka's law of scientific productivity. The top twelve producers, predominantly women, participated in 49.9% of the articles published. The journal showed low productivity and was of an endogamous nature, with a predominance of authors related to the School of Bromatology in the Faculty of Pharmacy, at the Complutense University. The subjects addressed reflected the demands of the nutrition transition in Spain.

Lotka's law and productivity index of authors in a scientific journal.

Lotka's law of scientific productivity is a bibliometric example: the number of authors against the number of contributions made by the authors was plotted on a logarithmic scale. The points were closely scattered around a straight line having a slope of -2. The purpose of this study was to apply information technology to real-world data and to quantify the extent of the bibliometric regularity that exists in the literature of dental science. We have analyzed the productivity index of authors (PI) in a scientific journal (Journal of American Dental Association). Details of a total of 4,088 papers published between 1966 and 1995 were extracted electronically from MEDLINE. The total number of authors was 5,589, responsible for 8,569 authorships. Only 0.8% of the authors presented a PI > = 1 (large producers), and 78.1% a PI = 0 (occasional authors). The number of authors publishing N papers was 1/N2.64 of those publishing one paper. The result suggested that repeated publications in the Journal were more difficult than those predicted by Lotka (1/N2).

The Simon-Yule approach to bibliometric modeling

Using an index approach to take into account the scattering pattern of the observed values, Chen and Leimkuhler showed that the three well-known bibliometric distributions (i.e., Lotka's law of scientific productivity, Bradford's law of bibliographic scattering, and Zipf's law of word frequency) are equivalent. Furthermore, Chen showed that Lotka's law can be derived from a generating mechanism (the Simon-Yule Model) proposed by Herbert A. Simon. In this paper, we use a simulation algorithm based on the Simon-Yule model to conduct computational experimentation on these three laws. The results indicate that the probability of a new entry (α), be it constant or decreasing, determines the characteristics of all three distributions.

Scientific productivity and accumulative advantage: a thesis reassessed in the light of international data

Ever since Lotka (1926) published his inverse square law of scientific productivity, both the nature and origin of the phenomenon have been investigated in the literature. Although the specific parameters of those functions which indicate what proportion of scientists produces what bulk of scientific products vary with different indices (Davis, 1941; Leavens, 1953; Price, 1963; Britton, 1964; Allison & Stewart, 1974; Knorr et al., 1975), there is general agreement that the distribution of scientific products is highly skewed, irrespective of the measurement chosen Of the discy,line investigated. Alternative hypotheses for explaining these diflerences among U.S. scientists were descn'bed by Cole & Cole (1973) and Allison & Stewart (1974). A third account of differences in pUblication rates is implied in a recent argument by Bourdieu (1975), and substantiated by Knorr (1977) and Knorr et al. (1978). The present paper will first summarize the various hypotheses offered in explanation, and then proceed to reassess the plausibility of accumulative advantage based upon data from an international study of scientific productivity conducted in 6 European countries from 1973 to 1977.

Indexing consistency and quality

AbstractA measure of indexing consistency is developed based on the concept of “fuzzy sets.” It assigns a higher consistency value if indexers agree on the more important terms than if they agree on less important terms. Measures of the quality of an indexer's work and exhaustivity of indexing are also proposed. Experimental data on indexing consistency is presented for certain categories of indexers; and consistency, quality, and exhaustivity values are compared and analyzed. The analysis of indexing exhaustivity leads to the conclusion that the increase of information as a result of group indexing is a process analogous to Bradford's law of information scattering, Lotka's law of scientific productivity, and Zipf's law of vocabulary distribution.
