Bibliometric profile of neurogenic bladder in the literature:a 20-year bibliometric analysis

Neurogenic bladder is a dysfunction of the lower urinary tract caused by nervous system disor- der. We investigated the trends in publication of articles under the topic ＂neurogenic bladder＂ using bibliometric analysis. Articles on neurogenic bladder, published between 1995 and 2014, were retrieved from the ISI Web of Science citation database. We analyzed the search results for authors, countries, institutions, journals, and top-cited papers. A total of 1,904 articles were re- trieved. There was a small increase in the number of articles on neurogenic bladder from 1995 （n = 43） to 2014 （n = 117）. The USA was the leading country in the total number of articles （n = 598）. However, the number of publications from China has rapidly increased, and China was ranked second in 2014. Emmanuel Chartier-Kastler （n = 65） was the most productive author, and University of Paris VI （Paris 6） （n = 61） was the most productive institution. The Journal of Urology published the greatest number of artides on this topic （n = 285）. Articles on neurogenic bladder were often published in a professional journal under the category Urology ＆ Nephrology, Neurosciences ＆ Neurology, or Rehabilitation. Visualization analysis based on co-citation networks was conducted using CiteSpace III. Visualization analysis revealed that the hot spots in neurogenic bladder were botulinum toxin-A, prazosin, bethanechol, and afferent pathways. These findings provide new insight into the publication trends and hot spots in neurogenic bladder.

The 100 most influential papers about cataract surgery:a bibliometric analysis

AIM：To identify the 100 most cited papers in cataract surgery,we performed a comprehensive bibliometric analysis basing on the literature search on the Thomson Reuters Web of Knowledge.METHODS：The number of citations,including the total citations,latest 5y citations and average citation number per year（ACY）,authorship,year of publication,major topics,journal of publication,country and institution of origin of each paper were recorded and then analyzed.Pearson’s correlation analysis was conducted to evaluate the correlation between the published year and the number of citations.The correlation between journal’s impact factor（IF）and number of citations was assessed as well.RESULTS：The most cited paper was the classic paper done by the European Society of Cataract＆Refractive Surgeons（ESCRS）group.This paper focused on the topic of endophthalmitis.Not only the most cited papers originated from the USA,but also some American institutions like Johns Hopkins University,Harvard Medical School,etc.had the most citations.Pearson’s correlation analysis indicated that the latest 5y citations and ACY were significantly related with the published year（5y citations：r=0.615,P〈0.001;ACY：r=0.657,P〈0.001）,whereas no association between the total number of citations and published year was found（r=0.045）.Moreover,the IFs of journals were found to have no significant effect on the number of total citations.CONCLUSION：To our knowledge,this is the first study on the most influential papers in cataract surgery aftera comprehensive research of relevant literatures.The present work may provide us concise information concerning the development history of cataract surgery over the past 66y.

Evolution of the Socio-cognitive Structure of Knowledge Management(1986–2015): An Author Co-citation Analysis

Purpose: The evolution of the socio-cognitive structure of the field of knowledge management(KM) during the period 1986–2015 is described. Design/methodology/approach: Records retrieved from Web of Science were submitted to author co-citation analysis(ACA) following a longitudinal perspective as of the following time slices: 1986–1996, 1997–2006, and 2007–2015. The top 10% of most cited first authors by sub-periods were mapped in bibliometric networks in order to interpret the communities formed and their relationships.Findings: KM is a homogeneous field as indicated by networks results. Nine classical authors are identified since they are highly co-cited in each sub-period, highlighting Ikujiro Nonaka as the most influential authors in the field. The most significant communities in KM are devoted to strategic management, KM foundations, organisational learning and behaviour, and organisational theories. Major trends in the evolution of the intellectual structure of KM evidence a technological influence in 1986–1996, a strategic influence in 1997–2006, and finally a sociological influence in 2007–2015.Research limitations: Describing a field from a single database can offer biases in terms of output coverage. Likewise, the conference proceedings and books were not used and the analysis was only based on first authors. However, the results obtained can be very useful to understand the evolution of KM research.Practical implications: These results might be useful for managers and academicians to understand the evolution of KM field and to(re)define research activities and organisational projects.Originality/value: The novelty of this paper lies in considering ACA as a bibliometric technique to study KM research. In addition, our investigation has a wider time coverage than earlier articles.

Co-author Weighting in Bibliometric Methodology and Subfields of a Scientific Discipline

Purpose: To give a theoretical framework to measure the relative impact of bibliometric methodology on the subfields of a scientific discipline, and how that impact depends on the method of evaluation used to credit individual scientists with citations and publications. The authors include a study of the discipline of physics to illustrate the method. Indicators are introduced to measure the proportion of a credit space awarded to a subfield or a set of authors.Design/methodology/approach: The theoretical methodology introduces the notion of credit spaces for a discipline. These quantify the total citation or publication credit accumulated by the scientists in the discipline. One can then examine how the credit is divided among the subfields. The design of the physics study uses the American Physical Society print journals to assign subdiscipline classifications to articles and gather citation, publication, and author information. Credit spaces for the collection of Physical Review Journal articles are computed as a proxy for physics.Findings: There is a substantial difference in the value or impact of a specific subfield depending on the credit system employed to credit individual authors.Research limitations: Subfield classification information is difficult to obtain. In the illustrative physics study, subfields are treated in groups designated by the Physical Review journals. While this collection of articles represents a broad part of the physics literature, it is not all the literature nor a random sample.Practical implications: The method of crediting individual scientists has consequences beyond the individual and affects the perceived impact of whole subfields and institutions. Originality/value: The article reveals the consequences of bibliometric methodology on subfields of a disciple by introducing a systematic theoretical framework for measuring the consequences.

A Bias-Free Time-Aware PageRank Algorithm for Paper Ranking in Dynamic Citation Networks

The process of ranking scientific publications in dynamic citation networks plays a crucial rule in a variety of applications. Despite the availability of a number of ranking algorithms, most of them use common popularity metrics such as the citation count, h-index, and Impact Factor (IF). These adopted metrics cause a problem of bias in favor of older publications that took enough time to collect as many citations as possible. This paper focuses on solving the problem of bias by proposing a new ranking algorithm based on the PageRank (PR) algorithm;it is one of the main page ranking algorithms being widely used. The developed algorithm considers a newly suggested metric called the Citation Average rate of Change (CAC). Time information such as publication date and the citation occurrence’s time are used along with citation data to calculate the new metric. The proposed ranking algorithm was tested on a dataset of scientific papers in the field of medical physics published in the Dimensions database from years 2005 to 2017. The experimental results have shown that the proposed ranking algorithm outperforms the PageRank algorithm in ranking scientific publications where 26 papers instead of only 14 were ranked among the top 100 papers of this dataset. In addition, there were no radical changes or unreasonable jump in the ranking process, i.e., the correlation rate between the results of the proposed ranking method and the original PageRank algorithm was 92% based on the Spearman correlation coefficient.

Citation classics in pediatrics: a bibliometric analysis

Background Citation analysis provides insights into the history and developmental trajectory of scientific fields. Our objec-tive was to perform an analysis of citation classics in the journals of pediatric specialty and to examine their characteristics. Methods Initially, all the journals listed under the category of pediatrics (n = 120) were identified using Journal Citation Reports. Web of science database was then searched (1950–2016) to select the top-100 cited articles in the above identified pediatric journals. The top-100 cited article were categorized according the study design, sub-specialty, country, institutional affiliation, and language. Results The top-100 articles were published in 18 different journals, with Pediatrics having the highest numbers (n = 40), followed by The Journal of Pediatrics (n = 17). The majority (n = 62) of classics were published after 1990. The most cited article had citation count of 3516 and the least cited had a citation count of 593. The USA (n = 71) was the most commonly represented country, and 60 institutions contributed to 100 articles. Fifteen authors contributed to more than one classic as first or second author. Observational study (n = 55) was the commonest study design across all decades, followed by reviews (n = 12), scale development studies (n = 11), and guidelines (n = 11). Among the pediatric sub-specialties, growth and development articles were highly cited (n = 24), followed by pediatric psychiatry and behavior (n = 21), endocrinology (n = 15), and neonatology (n = 12). Conclusions The top-100 cited articles in pediatrics identify the impactful authors, journals, institutes, and countries. Obser-vational study design was predominant—implying that inclusion among citation classics is not related to soundness of study design.

The Consistency Measurement in Document Publications and Citation Using t-Index

Recent time handling uncertainty and its measurement is considered as one of the major issues by data science and applied mathematics researchers. It becomes more complex when the dynamicity exists in data sets. One of the suitable examples is Scopus data sets which changes every time. In this case, precise measurement of consistency in document and citation publications is considered as one of the issues. It becomes more complex when the parameter like h-index and document count can be also manipulated over the period of time. To resolve this issue, a time-based index called as “t-index” is illustrated in this paper with an example. This method measures the randomness in document publication and citation using the average h-index and its entropy measurement.
