“…The empirical investigations of Lotka's assertions have been fundamental in generating new approaches and methodologies in the field of bibliometrics. A recent study by Yang et al (2014) offered another confirmation of this fact. To date, most EL 34,5 bibliometric analyses of scholarly communication have been focused on determining the applicability to Lotka's assertions.…”

Purpose -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. Design/methodology/approach -This study covers all the journal articles on HIV/AIDS pandemic in Nigeria over a period of five years (2008)(2009)(2010)(2011)(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. Findings -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. Research limitations/implications -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. Originality/value -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.

“…Since its introduction by Lotka in 1926, the versatility of Lotka's Law has been pivotal in bibliometric studies, and it has been expanded on through the years (Leydesdorff et al, 2013;Yang et al, 2014). Perceptions of research productivity patterns of authors differ…”

“…Uma das leis clássicas da bibliometria é a Lei de Lotka a qual afirma que a quantidade Y de autores que fazem X publicações sobre um determinado tema é aproximadamente 1/X 2 daqueles que publicam apenas uma vez ou, de forma geral, Y = C/X α , onde C e α são definidos de acordo com os dados observados (Lotka, 1926). Estudos demonstram que a Lei de Lotka apresenta aplicabilidade favorável na literatura de patentes (Yang et al, 2014). Dessa forma, foi realizada a distribuição de frequências da produtividade tecnológica dos inventores e assim verificou-se a aplicabilidade da lei.…”

Os sistemas de Agricultura de Precisão adotam diversos equipamentos de alta tecnologia em hardware, software e comunicação para coletar dados de diferentes fontes a fim de medir e avaliar todos os aspectos da produção agrícola. Essa estratégia de gestão permite a racionalização no uso dos recursos agrícolas, aumentando a eficiência da produção ao tempo que reduz os impactos negativos da atividade no campo. Este estudo teve por objetivo realizar o monitoramento das tecnologias associadas à Agricultura de Precisão, a partir da análise de informações dos documentos de patentes, de modo a investigar o estado e as tendências, bem como identificar os principais provedores e suas redes de colaboração. Questões de pesquisa foram formuladas para guiar o estudo, sendo este de caráter tanto quantitativo e descritivo, quanto qualitativo e exploratório. O estudo também fornece um fluxo metodológico apoiado por ferramentas de softwares gratuitos para coleta, tratamento e visualização de dados. Entre os principais resultados, destacam-se: 312 famílias de patentes depositadas por 303 requerentes e 968 inventores foram identificadas; 86% das publicações de patentes ocorreram na última década com tendência ao crescimento; as tecnologias foram depositadas em 23 países, com destaque para China e Estados Unidos; cerca de 86% dos titulares e inventores possuem apenas uma patente; plantio, processamento de dados e análise de propriedades do solo são os setores tecnológicos mais desenvolvidos; patentes altamente citadas; principais inventores participam de forma mais cooperativa que os titulares, sendo pontes entre diferentes grupos de inventores.

“…To calculate the frequency of publication by the authors, Lotka's Law was applied. The realistic investigations of Lotka's assertions have been vital in generating new methodologies and practices in the field of bibliometrics Yang et al (2014). To highlighten this, a certain rule between author frequency and quantity of papers was postulated by Lotka (1926).…”

This paper investigated the development example of nanotechnology from 2005 to May 2019 (15 years). The PubMed database has been utilized to recognize the job of Nanotechnology applications. Absolutely, 502 articles gathered including examination, survey and clinical preliminary were investigated, and the information are introduced in various table headings. Single-wrote papers with 48% of commitments have overwhelmed this field of research. US rules with huge commitments right now followed by England (26%). Dominant part of the productions were in English language (99%) and simply 0.2% distributed in the Chinese. It was intriguing to note 56% research articles were distributed right now. 5% productions were result of clinical preliminaries. The outcomes recommended that creator profitability dissemination anticipated for non-subject in Animal science. From this examination, analysts, researchers, subject masters, understudies, overseers, strategy creators, academicians, Library and Information Science experts and staff partners will be profited attributable to the logical and powerful examination.
