The effect of document types and sizes on the scaling relationship between citations and co-authorship patterns in management journals

The aim of this paper is to explore the power-law relationship between citation-based performance (CBP) and co-authorship patterns for papers in management journals by analyzing its behavior according to the type of documents (articles and reviews) and the number of pages of documents. We analyzed 36,241 papers that received 239,172 citations. The scaling exponent of CBP for article papers was larger than for reviews. Citations to articles increased 2^1.67 or 3.18 times each time the number of article papers published in a year in management journals doubled. The citations to reviews increased 2^1.29 or 2.45 times each time the number of reviews published in a year in management journals doubled. The scaling exponent for the power-law relationship of citation-based performance according to number of pages of papers was 1.44 ± 0.05 for articles and 1.25 ± 0.05 for reviews. The citations to articles increased faster than citation to reviews. The scaling exponent for the power-law of citation-based performance to co-authored articles was higher than single-authored articles. For reviews the scaling exponent was the same for the relationship between citation based performance and the number of reviews. Citations increased faster in single authored reviews than co-authored reviews.

The distribution of reference citations in two agricultural journals

The average numbers of references cited in papers published inN. Z. Journal of Experimental Agriculture (JEA) andN. Z. Journal of Agricultural Research (JAR) are compared. The papers inJAR have a greater number of references per paper than doJEA papers, probably becauseJAR papers are longer.ForJEA papers there is a steady increase in the average number of references per paper as the number of authors per paper increases. ForJAR there is no such steady increase but there is a marked increase in the average number of references per paper for 3- and 4+-author papers.There is a clear difference betweenJEA andJAR papers in the distribution of references between the different sections of the text. ForJEA papers 49% of references are cited in the Introduction and 52% are cited in the Results & Discussion sections. ForJAR the figures are 38% and 65% respectively.It is suggested that the distribution of cited references in the different sections of the text may be an indicator of the appliedness of a paper or of a journal.     

The use of citations matrices to group journals

A method of grouping journals within a wide discipline area into clusters is proposed, based on a algorithm that attempts to re-order a citations matrix so that it is block diagonal, or block recursive. The algorithm is based on a penalty function which allows one to account for the level of citation, not just the distribution of citations between journals. A case study involving eight economics journals is presented which illustrates the principles involved, but which also highlights the computational problems associated with extending the analysis to larger numbers of journals.The permission of the Institute for Scientific Information to access data from theSocial Science Citations Index ^® is gratefully acknowledged, as are the comments of a reviewer, who brought additional literature to my attention.     

A comparison between the journals nature and science

In this paper,Nature andScience, the two distinguished multi-disciplinary scientific journals were compared placing emphasis on their internationality. The items investigated were as follows. A general comparison: 1. number of authors per article, 2. distribution of countries to which first authors' institutions belong, 3. distribution of main discplines studied by first authors, 4. time-lag between the date of receipt of an article by the editor and the date of its publication. B. the position with regard to Japanese author: 1. number of Japanese authors, 2. relationship between the ranking of a Japanese author in the list of authors' names and the country where his institution is located, 3. relationship between the time-lag stated in A-4 and the items stated in B-2. As a result, it can be said thatNature is a more highly international journal thanScience.     

Analysis of the relationship between citation frequency of patents and diversity of their backward citations for Japanese patents

Conventional patent citation analyses have focused mainly on the presence of citation relationships, the number of patents cited by the subject patent, and the number of times the subject patent is cited by others (i.e., the numbers of backward and forward citations of the subject patent). However, most of them have not focused on patent classifications. Assuming that a patent based on a variety of technological bases tends to be an important patent that is cited more often, this study examines and clarifies the relationship between the diversity of classifications assigned to backward citations and the number of forward citations for Japanese patents. The results show notable differences in the number of classifications assigned to backward citations between the often cited and less frequently cited groups. It is considered that the diversity of backward citations can be utilized in the evaluation criteria for grouping that roughly identifies the often cited patents or eliminates a large part of less frequently cited patents.

The first mover and the challenger: The relationship between two journals in organization research

Many new journals are started in response to increasing specialization and limited space in existing journals. In this study two journals in organization research are studied,Administrative Science Quarterly as the first mover in the field andOrganization Studies as the challenger. It is shown that the new journal gradually differ from the old in terms of the national origin of its authors as well as the documents cited. It is concluded that the scientific journal market may not mirror the copy-cat behaviour found among newspapers or companies in other markets.     

Landmark papers written by the Nobelists in physics from 1901 to 2012: a bibliometric analysis of their citations and journals

We collected 382 landmark papers written by 193 Nobel Laureates in physics from 1901 to 2012 and used bibliometric methods, citation frequencies, impact factor (IF), and tendency of the landmark journals to analyze their contents. The results show: (1) Of landmark papers published during 1980–2009, 74.7 % were cited more than 500 times. Average citation frequencies and proportion of highly cited papers were higher for theoretic discoveries than for experimental methods. However, the proportion of highly cited papers in both domains was lower than for an invention. The average test period for the latter was markedly shorter too. (2) Landmark papers by Nobelists were mainly published in journals with IF from 5.0 to 10.0, but journals below IF 5.0 ranked first among all landmark journals. (3) As to countries where landmark papers were published, the Netherlands ranked at the top of the countries with the most landmark journals, besides the United States and England. In addition, the majority of landmark papers written by non-mainstream countries’ Nobelists were published in foreign journals with IF <7.0. These data indicate some regularity and tendency of landmark papers written by Nobelists in physics.     

Succinct effect or informative effect: the relationship between title length and the number of citations

Previous studies produced mixed results with respect to the correlation between title length and number of citations. This research aims to provide a new explanation for this controversy by examining one of the largest pools of papers to date, containing over 300,000 economics papers spanning a much longer time period (1956–2012). The results show that correlation between title length and the number of citations is negative between 1956 and 2000, but becomes positive after 2000, when online searches became the predominant method for literature retrieval. Moreover, heterogeneity analyses show that longer titles are especially crucial for papers with relatively lower influence, which researchers can typically only access using online searches.     

Relationship between international collaboration papers and their citations from an economic perspective

This paper analyzes the relationship among international collaboration, number of papers and number of citations from an economic perspective. It analyzes the number of international collaboration papers and their citations according to different international economic collaboration types, the number of countries at different economic levels, and the economic situations of first or corresponding authors. This study analyzes international collaboration papers listed in Web of Science from 2011 to 2015, published in the field of Public, Environmental and Occupational Health. According to different international collaboration types, results show that the subset of international collaboration with the same economic level accounts for the highest percentage, especially the type of H&H, and there are significant differences in average citations among different collaboration types, the type of H&M&L has the highest value (11.21?±?15.72). According to the number of countries at different economic levels, results show that papers published by ≥?3 countries account for the highest percentage most of the time in different collaboration types. In general, there are positive correlations between the number of countries and citations, but there are no significant differences according to the number of low income countries in different types except H&M&L. According to economic situations of first or corresponding authors, results show that papers initiated by high income countries always account for the highest percentage over past 5 years, and there are positive correlations between the economic situations of first or corresponding authors and citations in different types except H&M. (H: high income countries, M: middle income countries, L: low income countries).     

Problem of the physical nature of relationship between micro- and macroyielding

The results are examined of investigations into the effect of the grain size and the type of crystal lattice of polycrystalline material on the yield limit in a multiaxial stress state and the form of the limiting yield curve of carbon steels. Reasons for the transformation of the yielding surface of these materials with temperature variation are examined. A yielding criterion of polycrystalline materials with fcc and bcc lattices is proposed and experimentally justified.Translated from Problemy Prochnosti, No. 3, pp. 68–73, March, 1990.     

Computer models for identifying instrumental citations in the biomedical literature

The most popular method for evaluating the quality of a scientific publication is citation count. This metric assumes that a citation is a positive indicator of the quality of the cited work. This assumption is not always true since citations serve many purposes. As a result, citation count is an indirect and imprecise measure of impact. If instrumental citations could be reliably distinguished from non-instrumental ones, this would readily improve the performance of existing citation-based metrics by excluding the non-instrumental citations. A citation was operationally defined as instrumental if either of the following was true: the hypothesis of the citing work was motivated by the cited work, or the citing work could not have been executed without the cited work. This work investigated the feasibility of developing computer models for automatically classifying citations as instrumental or non-instrumental. Instrumental citations were manually labeled, and machine learning models were trained on a combination of content and bibliometric features. The experimental results indicate that models based on content and bibliometric features are able to automatically classify instrumental citations with high predictivity (AUC = 0.86). Additional experiments using independent hold out data and prospective validation show that the models are generalizeable and can handle unseen cases. This work demonstrates that it is feasible to train computer models to automatically identify instrumental citations.     

The log-linear relation between patent citations and patent value

This paper reports the results of an analysis of patent citation and patent renewal data, advancing a log-linear relation between patent citations and patent value. A complementary analysis of firms’ patent portfolios confirms that modelling the relation between citations and firm value benefits from the adoption of the log-linear form.     

An empirical analysis of the relationship between individual characteristics and research productivity

This paper provides an analysis of the relationship between research performance and individual characteristics (e.g., career path information) of researchers, based on information provided in the curriculum vitaes of 565 excellent researchers within the life sciences and medical sciences fields in Japan. I specifically analyzed the relationship between the experiences of practical physicians and research performance. As a result, I found that the experience as a practical physician had a statistically positive relationship with the number of research papers, but there was not a significant relationship with the number of citations. Moreover, the diversity of a researcher’s career related significantly to the number of citations and patents. An employment experience at a young age with a company or independent administrative agency had a significant and positive relationship with number of coauthors. However, a significant relationship between work experience in a foreign country and research performance was not observed.

Modeling the obsolescence of research literature in disciplinary journals through the age of their cited references

There are different citation habits in the research fields that influence the obsolescence of the research literature. We analyze the distinctive obsolescence of research literature in disciplinary journals in eight scientific subfields based on cited references distribution, as a synchronous approach. We use both negative binomial (NB) and Poisson distributions to capture this obsolescence. The corpus being examined is published in 2019 and covers 22,559 papers citing 872,442 references. Moreover, three measures to analyze the tail of the distribution are proposed: (i) cited reference survival rate, (ii) cited reference mortality rate, and (iii) cited reference percentile. These measures are interesting because the tail of the distribution collects the behavior of the citations at the time when the document starts to get obsolete in the sense that it is little cited (used). As main conclusion, the differences observed in obsolescence are so important even between disciplinary journals in the same subfield, that it would be necessary to use some measure for the tail of the citation distribution, such as those proposed in this paper, when analyzing in an appropriate way the long time impact of a journal.
