Literature Review on Control Charts for Autocorrelated Processes

This research aims to present a literature review (LR) on control charts for autocorrelated processes, intending to contribute to the scientific knowledge of the process management area. The article was constructed having a research question defined ex-ante, elaborated based on the literature, where a research protocol adapted from Tranfield, Denyer, and Smart (2003) was systematized according to the methodological rigor demanded in the literature review, which resulted in the composition of the research corpus. The research corpus was evaluated in detail using the bibliometric packages HistCite, VOSviewer, package R and Iramuteq. It was evaluated the validity of the 3 bibliometric laws were verified: Lotka's Law, Bradford's Law, and Zipf's Law based on the authors’ citation and co-citation techniques. This study is considered as relevant and original since it is the first literature review on control charts for autocorrelated processes. The results confirmed the 3 classical bibliometric laws for the researched corpus. As a practical implication, this review provides support for quality management scholars to unlock potential research gaps. The main limitation of the work refers to the composition of the textual corpus, given that databases of national journals were not consulted due to the difficulty in terms of compatibility of the software used in this research.

Bitcoin: an analysis of the accounting and finance research published in international journals

This paper consists of a literature review and a survey of scientific research published in journals about the theme cryptocurrencies. In a descriptive study, we used bibliometrics and the content analysis of articles that address the central theme, bitcoin. The study analysed 337 articles. The number of studies has been increased in the period from 2013 to 2018. The findings corroborate with the law of Bradford (many journals with few articles) and will meet with the Lotka's law (80% of the authors are logged only one study on the theme). The majority of researches conducted, in short, comparative studies with indexes and mathematical properties, using statistical tools such as analysis of variance and regression. It generally noted the lack of research on the topic in Brazilian journals, which enables opportunities for future studies.

FELICIDADE NO TRABALHO: MAPEAMENTO DA PRODUÇÃO CIENTÍFICA DA ÚLTIMA DÉCADA POR MEIO DE ANÁLISE BIBLIOMÉTRICA

The aim of this article was to investigate the configuration of scientific production on job happiness, taking as source the main international databases, the ISI Web of Science (WOS) and Scopus, in the 2011-2020 timeframe. From a methodological point of view, the study was developed following the laws of Bradford, Lotka and Zipf in search of the main authors and their productivity, related topics covered and their evolution in the period 2011-2020. Data were processed using R and Excel® software. The study results allow us to state that happiness at work is being considered as part of the well-being construct in the main publications on the subject. However, it is necessary to consider happiness “in the organizational environment”, not just “at work”, appropriating the term happiness and developing a new construct of the concept.

ЧАСТОТНЫЕ СВОЙСТВА ЛЕКСИКИ НАУЧНЫХ ТЕКСТОВ И ЗАКОНЫ ЦИПФА ВЫСШИХ ПОРЯДКОВ

The statistical properties of the lexis of texts in natural languages have attracted the close attention of many mathematicians and linguists over the past hundred years. The basic law of the dependence of the word frequency on its rank, which is known as Zipf’s law, is that the product of the frequency of a word and its rank is approximately constant and is a marker of the text language. It should be noted that numerous analogs of Zipf’s law in other subject areas have great practical significance for describing the functioning of various sociotechnical systems: Auerbach’s law of the distribution of cities by population, Pareto’s law of the distribution of material goods in society, Bradford’s law of the distribution of scientists by productivity, Lotka law of the distribution of publications in bibliographic sources. The article considers the latent frequency characteristics of the lexis of scientific texts on various topics by the array of articles in the multidisciplinary open access journal “Young Scientist”. The paper formulates the concept of a higher-order frequency table and empirically investigates the dependence of frequencies in such tables on their ranks. Power, hyperbolic, and other twoparameter models of the dependence of frequencies on ranks in tables of frequencies of higher orders were constructed for all articles from the corpus of texts under consideration. The constructed models are generalizations of the well-known Zipf models and have high quality indicators. In the paper, new predictors are obtained, which can be useful for solving problems of classifying scientific texts.

ANALYSIS OF OBSOLESCENCE AND PRODUCTIVITY OF AUTHORS USING LOTKA LAW ON THE JOURNAL OF ENTREPRENEURSHIP IN 2015 – 2019

This research was conducted to determine the level of obsolescence of a literature and determine the author's productivity with the law of lotka in the literature on entrepreneurship in 2015-2019. The research method used is quantitative research methods by conducting citation analysis. In analyzing data, data is collected, submitted, processed and then presented in tables and graphs. The result of the research is the obsolescence level of the literature with an article entitled "The Effect of Organizational Citizenship Behavior on Performance with Service Quality, Satisfaction and Behavior Intention as Antecedents" with the obsolescence of literature and half-life of the last 17 years. And the shortest time for literature obsolescence is only 5 years, the article is entitled: "The Effect of Using Cooperative Learning Type Think-Pair-Share (Tps) on Entrepreneurship Learning Outcomes of Class X Students of Even Semester SMP Kartikatama 1 Metro T.P 2015/2016". Then for the calculation of authors who are often cited, namely I Ghozali, Singh, Sangeeta, Wafa, S.A and Suharti L. Each of the authors of the articles is the writer with the second rank on the subject of entrepreneurship. Most of the writers produce one article. The most productive writer produced 4 articles and got first place, namely Wiliams, then Muhammad Hassan and Berry L were in second place by producing 2 articles in the 2015-2019 period while the third rank was occupied by authors who produced 1 article in the 2015-2019 period, namely as many as 156 authors. Based on the test of Lotka's law on Entrepreneurship articles, it has an exponential value of (n) 3.7537, with the set (C) 0.9127 or 91.27%. From the graph it can be seen that there is a relationship between the number of authors and the number of articles produced as in the lotka law. The fewer the number of writers, the more articles are produced.

A Bibliometric and Mapping Analysis of Glaucoma Research between 1900 and 2019

To explore the relevance of scientific production on glaucoma using bibliometric tools. Bibliographic study. Original articles published from 1900 through2019. We performed a search in Web of Science for documents published between 1900 and 2019. We used bibliometric indicators to explore documents production, dispersion, distribution, time of duplication, and annual growth, as characterized by Price's law of scientific literature growth, Lotka's law, the transient index, and the Bradford model. We also calculated the participation index of different countries and institutions. Finally, we explored with bibliometric mapping the co-occurrence networks for the most frequently used terms in glaucoma research. Bibliometric indicators for individuals, institutions, and countries. A total of 33 631 original articles were collected from the timeframe 1900 through 2019. Price's law showed an exponential growth. Scientific production was adjusted better to exponential growth (r= 0.967) than linear growth (r= 0.755). Literature on glaucoma research increased its growth in the last 30 years at a rate of 5.1% per year with a production that doubled its size every 13.9 years. The transience index was 60.08%; this indicates that most of the scientific production is the output of very few authors. Bradford's law showed a high concentration of articles published in a small core of specialized journals. Lotka's law indicated that the distribution of authors is concentrated heavily in small producers. The United States and University of London demonstrated the highest production of original articles. Map network visualization showed the generated term map detailing clusters of closely related terms. Glaucoma literature has grown exponentially. A very high rate of transience was found that indicates the presence of numerous authors who sporadically publish on this topic. No evidence of a saturation point in the glaucoma literature was observed.

Bibliometric Analysis of COVID-19 Publications in the Field of Chest and Infectious Diseases

Aim: At the context of the chest and infectious diseases, the main goal of this study is to make a bibliometric analysis of publications on coronavirus disease 2019 (COVID-19). Visualizing it with visible and scientific mapping techniques is the secondary goal. Material and Methods: Raw data for 2020 have been downloaded from the Web of Science Core Collection database. A total of 787 articles were reviewed. Raw data were analyzed with Bibliometrix and VOSviewer. The articles about COVID-19, related with the respiratory system and infectious diseases were included. The perspectives of other disciplines were excluded with the analysis. Results: A total of 787 articles were published in 108 different journals. The average number of citations per article is 10.17. There are four studies with over 300 citations. The top three authors with the highest H index are Raoult D, Colson P and Rolasin JM. The h, g and m indices of the authors were calculated and the core authors were determined according to Lotka's law. The top three countries that publish the most articles are China, America and Italy. Finally, according to the word mining analysis, it was determined that the studies can be classified under three clusters. Conclusion: One of the tools that will accelerate the basic reading process in the face of the numerical increase rate of publications on COVID-19 is the bibliometric analysis results. The most up-to-date and basic information on treatment options can be found collectively in bibliometric studies.

DEVELOPMENT OF MATHEMATICAL FUNDAMENTALS OF SOCIAL COMMUNICATIONS

The purpose of the article is to generalize the patterns of phenomena and processes of social communications and to develop on this basis their unified mathematical model. The methodology is a systematic, infometric, and synergetic approaches to the development of mathematical principles of socialcommunication. The first one (systematic) is to generalize the empirical patterns of scaling in librarianship, linguistics, and science. The second one (infometric) is to obtain an analytical description of the quantitative relationship between the subjects and objects of social communications, the thirdone (synergetic) is to create their unified mathematical model. The scientific novelty of the work lies in the development of ideas about the large-scale invariance of phenomena and processes of social communications, which are approximated by the empirical laws of Bradford, Lotka, and Zipf. A comprehensive analysis of these patterns was performed, and it was stated that they differ only in areas of use, and we should raise the question of establishing a unified mathematical model of these patterns. The necessity of using stable laws of distribution of probability theory for the analytical description of the phenomenon of scaling and self-organization of social communication processes was substantiated. It was found that the considered processes are described by a stable distribution law with a characteristic coefficient equal to the constant of the golden section. Conclusions. Bradford’s lawof concentration and scattering of information, Zipf’s linguistic-statistical law, and Lotka’s law of distribution of scientists by publishing activity are manifestations of latent relations between subjects and objects of social communication (authors, publications, terminology, etc.). Clarifying these hidden relationships and defining the mathematical apparatus for their accurate description and analysis, as was done in the study, will ensurethe development of the scientific base of social communications and the transition from approximation to analytical research in this area.Key words: social communications, mathematical models, scale invariance, probability theory, stable distributions, self-organization.

Flipped classroom in the second decade of the Millenia: a Bibliometrics analysis with Lotka's law.

This paper aims to examine the current dynamics of the flipped classroom studies and to propose a direction for future research for the field. Using a bibliometric approach, we observe a sample of 1557 documents from the Scopus database to identify research activity on the flipped classroom. The keywords “flipped classroom” and “flipped learning” have been executed in the search query. We presented the earlier stage of research in the flipped classroom, the subsequent trends, publications status based on source title, country and institution and examined citations pattern of the publication. We also discuss the themes based on the occurrences and terms of the keywords, title and abstract of the documents. This paper also predicts the future study in the flipped classroom using Lotka’s law. We found that the pattern distribution of the author’s contribution fits with the law. We conclude by suggesting a few potential research directions on the flipped classroom. Research on flipped classroom focuses on approaches, strategies and effectiveness perceived by practitioners and learners with relatively less attention on author’s contribution and the prediction on their future and sustainable contribution and networking in guaranteeing the survival and expansion of flipped classroom approach for the coming decades.

A teoria dos stakeholders no Brasil: produção acadêmica no período de 2014 a 2019

Objetivo: Analisar o perfil da produção recente sobre Teoria dos Stakeholders nos periódicos nacionais.Método: Revisão de literatura, na qual foram selecionados 271 artigos publicados, entre 2014 e 2019, em 92 periódicos do estrato superior do Qualis/CAPES em Administração e áreas afins. Originalidade/Relevância: O conhecimento acerca do referido perfil auxilia os pesquisadores a visualizarem aspectos metodológicos e conceituais a partir dos quais o tema está sendo discutido, contribuindo para a definição de uma agenda de pesquisa.Resultados: A RBGN, a RAUFSM e a RIAE são os periódicos de referência. A maioria dos estudos adota uma abordagem teórico-empírica e possui natureza qualitativa, sendo a pesquisa documental e a entrevista os instrumentos de coleta de dados mais utilizados. A análise de conteúdo foi a técnica de análise de dados mais aplicada. A definição de Stakeholder de Freeman e o modelo de análise de Mitchell, Agle e Wood são os mais empregados. A pesquisa sobre o tema é crescentemente colaborativa, bem como foi possível constatar a validação das Leis de Bradford e Zipf, mas não a de Lotka. Portanto, é possível identificar um grupo de periódicos mais devotos ao tema e os termos que apresentam maior frequência nos artigos pesquisados. Entretanto, não foi possível comprovar que uma larga proporção da literatura foi produzida por um pequeno número de autores. Contribuições teóricas/metodológicas: Foram identificadas lacunas na literatura e tendências, como o diálogo entre a Teoria de Stakeholder e a geração de valor, que foram objeto da agenda de pesquisa sugerida.

Thirty Years of Psicothema: A Bibliometric Analysis (1989-2018).

This study presents a bibliometric analysis of Psicothema as a commemoration for its 30 years of publishing (1989-2018). A year-, sex-, and publication language-based analysis of the journal's characteristics was carried out based on the sample of 2,396 publications. Based on that data, Lotka's law was assessed, Lawani and Subramanyam indices and cooperation networks were estimated, the Pratt index was calculated, the concentration of papers according to thematic areas and research methods was described, and citations and impact indicators were obtained according to the original articles indexed in Web of Science (1993-2018). The results indicated greater participation by male authors, increased publication in English, compliance with Lotka's law, and a greater inter-institutional contribution in recent decades. There was a higher percentage of methodology/psychometrics-related work, and most of these publications used quantitative methods. The impact factor and the amount of citations reached its peak in 2018. The characteristics of Psicothema, which is a model of scientific communication of psychology in the international context, are discussed in this study.
