Electronic theses and dissertations: a review of this valuable resource for nurse scholars worldwide.

Science.gov (United States)

Goodfellow, L M

2009-06-01

A worldwide repository of electronic theses and dissertations (ETDs) could provide worldwide access to the most up-to-date research generated by masters and doctoral students. Until that international repository is established, it is possible to access some of these valuable knowledge resources. ETDs provide a technologically advanced medium with endless multimedia capabilities that far exceed the print and bound copies of theses and dissertations housed traditionally in individual university libraries. CURRENT USE: A growing trend exists for universities worldwide to require graduate students to submit theses or dissertations as electronic documents. However, nurse scholars underutilize ETDs, as evidenced by perusing bibliographic citation lists in many of the research journals. ETDs can be searched for and retrieved through several digital resources such as the Networked Digital Library of Theses and Dissertations (http://www.ndltd.org), ProQuest Dissertations and Theses (http://www.umi.com), the Australasian Digital Theses Program (http://adt.caul.edu.au/) and through individual university web sites and online catalogues. An international repository of ETDs benefits the community of nurse scholars in many ways. The ability to access recent graduate students' research electronically from anywhere in the world is advantageous. For scholars residing in developing countries, access to these ETDs may prove to be even more valuable. In some cases, ETDs are not available for worldwide access and can only be accessed through the university library from which the student graduated. Public access to university library ETD collections is not always permitted. Nurse scholars from both developing and developed countries could benefit from ETDs.

Status of research methods used in the dissertations of graduates from Tabriz University of Medical Sciences (Assistantship, MD, Board and MSc for the years 1996-2006

Full Text Available   The present study seeks to examine the status of research methods employed in dissertations submitted by graduates of Tabriz University of Medical Sciences. The study also examined the impact factors. Using content analysis, the research methods were divided into four groups: historical, descriptive, empirical and literature review. The distributions for each method were calculated on the basis of gender, graduate level, citations, time frame and fields of study. Samples were chosen randomly from among the dissertations available at faculty libraries at TUMS. 390 dissertations were selected. Findings demonstrated that gender did not influence the choice of research method. With exception of Nursing faculty, graduate level proved to be an prominent factor when choosing research method. All types of citations (books, journals, online and non-printed sources were identified as another significant factor impacting pushing towards any given research method. With exception of Hygiene and Food Faculty, the time factor affected the research method selection process as well. Finally, given their different research characteristics, the field of studies investigated also contributed to both the scope and direction of research methods chosen.

Tolisano, Anthony M; Song, Sungjin A; Cable, Benjamin B

2016-02-01

To determine the prevalence of author self-citation in the field of otolaryngology. A retrospective review of bibliographic references in 5 otolaryngology journals. Five high-impact otolaryngology journals were reviewed over a 3-month period between January and March 2014 to identify the pattern of author self-citations. Data included study type, otolaryngology topic, authorship, total citations, author self-citations, and country of origin. Nearly two-thirds of articles contained at least 1 self-citation, with an average of 2.6 self-citations per article. Self-citations represented nearly 10% of total citations. Articles with at least 1 self-citation had more authors (5.8 vs 4.9, P otolaryngology literature is common and compares similarly to other medical specialties previously studied. Self-citation should not be considered inappropriate, as it is often done to expand on earlier research. Nevertheless, editors, researchers, and readers should be aware of this increasingly recognized phenomenon and its associated potential implications to the process of scientific inquiry. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

This study examines the determinants of citation success among authors who have recently published their work in economic history journals. Besides offering clues about how to improve one's scientific impact, our citation analysis also sheds light on the state of the field of economic history...... find similar patterns when assessing the same authors' citation success in economics journals. As a novel feature, we demonstrate that the diffusion of research — publication of working papers, as well as conference and workshop presentations — has a first-order positive impact on the citation rate........ Consistent with our expectations, we find that full professors, authors appointed at economics and history departments, and authors working in Anglo-Saxon and German countries are more likely to receive citations than other scholars. Long and co-authored articles are also a factor for citation success. We...

Aberration of the Citation.

Science.gov (United States)

Moustafa, Khaled

2016-01-01

Multiple inherent biases related to different citation practices (for e.g., self-citations, negative citations, wrong citations, multi-authorship-biased citations, honorary citations, circumstantial citations, discriminatory citations, selective and arbitrary citations, etc.) make citation-based bibliometrics strongly flawed and defective measures. A paper can be highly cited for a while (for e.g., under circumstantial or transitional knowledge), but years later it may appear that its findings, paradigms, or theories were untrue or invalid anymore. By contrast, a paper may remain shelved or overlooked for years or decades, but new studies or discoveries may actualize its subject at any moment. As citation-based metrics are transformed into "commercial activities," the "citation credit" should be considered on a commercial basis too, in the sense that "citation credit" should be shared out as a "citation dividend" by shareholders (coauthors) averagely or proportionally to their contributions but not fully appropriated by each of them. At equal numbers of citations, the greater number of authors, the lower "citation credit" should be and vice versa. Overlooking the presence of distorted and subjective citation practices makes many people and administrators "obsessed" with the number of citations to such an extent to run after "highly cited" authors and to create specialized citation databases for commercial purposes. Citation-based bibliometrics, however, are unreliable and unscientific measures; citation counts do not mean that a more cited work is of a higher quality or accuracy than a less cited work because citations do not measure the quality or accuracy. Citations do not mean that a highly cited author or journal is more commendable than a less cited author or journal. Citations are not more than countable numbers: no more, no less.

Citation networks of related trials are often disconnected: implications for bidirectional citation searches.

Robinson, Karen A; Dunn, Adam G; Tsafnat, Guy; Glasziou, Paul

Reports of randomized controlled trials (RCTs) should set findings within the context of previous research. The resulting network of citations would also provide an alternative search method for clinicians, researchers, and systematic reviewers seeking to base decisions on all available evidence. We sought to determine the connectedness of citation networks of RCTs by examining direct (referenced trials) and indirect (through references of referenced trials, etc) citation of trials to one another. Meta-analyses were used to create citation networks of RCTs addressing the same clinical questions. The primary measure was the proportion of networks where following citation links between RCTs identifies the complete set of RCTs, forming a single connected citation group. Other measures included the number of disconnected groups (islands) within each network, the number of citations in the network relative to the maximum possible, and the maximum number of links in the path between two connected trials (a measure of indirectness of citations). We included 259 meta-analyses with a total of 2,413 and a median of seven RCTs each. For 46% (118 of 259) of networks, the RCTs formed a single connected citation group-one island. For the other 54% of networks, where at least one RCT group was not cited by others, 39% had two citation islands and 4% (10 of 257) had 10 or more islands. On average, the citation networks had 38% of the possible citations to other trials (if each trial had cited all earlier trials). The number of citation islands and the maximum number of citation links increased with increasing numbers of trials in the network. Available evidence to answer a clinical question may be identified by using network citations created with a small initial corpus of eligible trials. However, the number of islands means that citation networks cannot be relied on for evidence retrieval. Copyright © 2014 Elsevier Inc. All rights reserved.

An overview of the Data Citation Index is provided. Thomson Reuters developed this resource in response to a stated desire among members of the research community for increased attribution of non-traditional scholarly output. Launched in October of 2012 on the Web of science research platform, its aims include linking published research articles to their underlying data sets and tracking the citation of the data, as well as encouraging bibliographic citation of data. Cross-disciplinary search capabilities in the Index enable new possibilities for data discovery and synthesis. Data repositories are evaluated with respect to various selection criteria, with particular attention to their relevance to scientific and scholarly research. Index content reflects current data deposition practices. As data citation standards and practices continue to move toward widespread formalization and adoption, the initiative seeks to address issues of data citation, reuse, and author credit in a developing climate.

A recent review of frameworks used in dissemination and implementation (D&I) science described 61 judged to be related either to dissemination, implementation, or both. The current use of these frameworks and their contributions to D&I science more broadly has yet to be reviewed. For these reasons, our objective was to determine the role of these frameworks in the development of D&I science. We used the Web of Science™ Core Collection and Google Scholar™ to conduct a citation network analysis for the key frameworks described in a recent systematic review of D&I frameworks (Am J Prev Med 43(3):337-350, 2012). From January to August 2016, we collected framework data including title, reference, publication year, and citations per year and conducted descriptive and main path network analyses to identify those most important in holding the current citation network for D&I frameworks together. The source article contained 119 cited references, with 50 published articles and 11 documents identified as a primary framework reference. The average citations per year for the 61 frameworks reviewed ranged from 0.7 to 103.3 among articles published from 1985 to 2012. Citation rates from all frameworks are reported with citation network analyses for the framework review article and ten highly cited framework seed articles. The main path for the D&I framework citation network is presented. We examined citation rates and the main paths through the citation network to delineate the current landscape of D&I framework research, and opportunities for advancing framework development and use. Dissemination and implementation researchers and practitioners may consider frequency of framework citation and our network findings when planning implementation efforts to build upon this foundation and promote systematic advances in D&I science.

Electronic theses and dissertations management in Brazil: about digital libraries of theses and dissertations and institutional repositories

Directory of Open Access Journals (Sweden)

Fernando César Lima Leite

2015-12-01

Full Text Available Introduction: This paper presents analysis on the management of electronic theses and dissertations in the Brazilian context. The dilemmas of digital library of theses and dissertations and institutional repositories coexistence and its implications are discussed and possible paths to be considered by actors, in the institutional and national level. Objective: Present and analyze implications of the digital library of theses and dissertations and institutional repositories coexistence as management systems and, moreover, propose and discuss alternatives faced by actors responsible for its management at the institutional and national levels. Methodology: Data on the status of theses and dissertations management systems were obtained by IBICT. The analysis allowed to group the Brazilian institutions in three major categories that represent the current state of management of theses and dissertations in Brazil. Results: The settings were obtained from three major scenarios and their institutional and national implications for the management of theses and dissertations. Of these settings were listed alternative solutions to the problems identified. Conclusions: Among the findings stand out: the continuity of the IBICT’s Brazilian Digital Library of Theses and Dissertations (BDTD does not necessarily imply the continuity of the digital library of theses and dissertations; Investment in institutional repositories does not mean the end of BDTD; Part of Brazilian universities and research institutions do not enjoy conditions that allow them to effectively maintain the two systems.

[The path to "Doctor of Medicine"--how do doctoral candidates evaluate their dissertation?].

Weihrauch, M; Weber, A; Weltle, D; Pabst, R; Lehnert, G

1998-03-27

The value of medical dissertations has for some time been controversial. Critical opinions have, on the one hand, been directed against the effort required, its duration and the concept behind these dissertations, while asserting, on the other hand, that such dissertations hinder studying and lead to unnecessary lengthening of the medical curriculum. In collaboration with the Medical School in Hanover a questionnaire was sent to all the 189 dissertationists of one year, to be returned anonymously. It contained 16 questions about the dissertation itself, supervision. time spent on it, total duration of medical course and effect of the dissertation on the individual's medical studies. The answers were evaluated statistically by explorative data analysis. 181 questionnaires could be evaluated (96%). Average age of those questioned was 30.5 years, median duration of medical studies to-data was 13 semesters. For 80% it was the first attempted dissertation. 22% had been working on an entirely experimental topic (laboratory or animal experiments). The median time from starting to submitting the dissertation was 4 years, the median time of the experimental phase one year. Two-thirds of students said that work on the dissertation had not prolonged their studies. Supervision during various phases of the dissertation was overwhelmingly judged to have been "very good" or "good". Altogether 90% of dissertationists thought that it had been personally meaningful, and they would recommend it to younger costudents. The results of this study show that a universal criticism of medical dissertations does not stand up to detailed enquiry. Successful dissertationists highly rated their value both to themselves and to scientific medicine. The medical dissertation should therefore firmly remain as part of medical studies and of research within them.

The measurement of the effect on citation inequality of differences in citation practices across scientific fields.

Science.gov (United States)

Crespo, Juan A; Li, Yunrong; Li, Yungrong; Ruiz-Castillo, Javier

2013-01-01

This paper has two aims: (i) to introduce a novel method for measuring which part of overall citation inequality can be attributed to differences in citation practices across scientific fields, and (ii) to implement an empirical strategy for making meaningful comparisons between the number of citations received by articles in 22 broad fields. The number of citations received by any article is seen as a function of the article's scientific influence, and the field to which it belongs. A key assumption is that articles in the same quantile of any field citation distribution have the same degree of citation impact in their respective field. Using a dataset of 4.4 million articles published in 1998-2003 with a five-year citation window, we estimate that differences in citation practices between the 22 fields account for 14% of overall citation inequality. Our empirical strategy is based on the strong similarities found in the behavior of citation distributions. We obtain three main results. Firstly, we estimate a set of average-based indicators, called exchange rates, to express the citations received by any article in a large interval in terms of the citations received in a reference situation. Secondly, using our exchange rates as normalization factors of the raw citation data reduces the effect of differences in citation practices to, approximately, 2% of overall citation inequality in the normalized citation distributions. Thirdly, we provide an empirical explanation of why the usual normalization procedure based on the fields' mean citation rates is found to be equally successful.

A generalized view of self-citation: direct, co-author, collaborative, and coercive induced self-citation.

Science.gov (United States)

Ioannidis, John P A

2015-01-01

The phenomenon of self-citation can present in many different forms, including direct, co-author, collaborative, and coercive induced self-citation. It can also pertain to the citation of single scientists, groups of scientists, journals, and institutions. This article presents some case studies of extreme self-citation practices. It also discusses the implications of different types of self-citation. Self-citation is not necessarily inappropriate by default. In fact, usually it is fully appropriate but often it is even necessary. Conversely, inappropriate self-citation practices may be highly misleading and may distort the scientific literature. Coercive induced self-citation is the most difficult to discover. Coercive Induced self-citation may happen directly from reviewers of articles, but also indirectly from reviewers of grants, scientific advisors who steer a research agenda, and leaders of funding agencies who may espouse spending disproportionately large funds in research domains that perpetuate their own self-legacy. Inappropriate self-citation can be only a surrogate marker of what might be much greater distortions of the scientific corpus towards conformity to specific opinions and biases. Inappropriate self-citations eventually affect also impact metrics. Different impact metrics vary in the extent to which they can be gamed through self-citation practices. Citation indices that are more gaming-proof are available and should be more widely used. We need more empirical studies to dissect the impact of different types of inappropriate self-citation and to examine the effectiveness of interventions to limit them. Copyright © 2014.

The scientific community has long depended on consistent citation of the scientific literature to enable traceability, support replication, and facilitate analysis and debate about scientific hypotheses, theories, assumptions, and conclusions. However, only in the past few years has the community focused on consistent citation of scientific data, e.g., through the application of Digital Object Identifiers (DOIs) to data, the development of peer-reviewed data publications, community principles and guidelines, and other mechanisms. This means that, moving ahead, it should be easier to identify and track data citations and conduct systematic bibliometric studies. However, this still leaves the problem that many legacy datasets and past citations lack DOIs, making it difficult to develop a historical baseline or assess trends. With this in mind, the NASA Socioeconomic Data and Applications Center (SEDAC) has developed a searchable citations database, containing more than 3,400 citations of SEDAC data and information products over the past 20 years. These citations were collected through various indices and search tools and in some cases through direct contacts with authors. The citations come from a range of natural, social, health, and engineering science journals, books, reports, and other media. The database can be used to find and extract citations filtered by a range of criteria, enabling quantitative analysis of trends, intercomparisons between data collections, and categorization of citations by type. We present a preliminary analysis of citations for selected SEDAC data collections, in order to establish a baseline and assess options for ongoing metrics to track the impact of SEDAC data on interdisciplinary science. We also present an analysis of the uptake of DOIs within data citations reported in published studies that used SEDAC data.

Improving MeSH classification of biomedical articles using citation contexts.

Science.gov (United States)

Aljaber, Bader; Martinez, David; Stokes, Nicola; Bailey, James

2011-10-01

Medical Subject Headings (MeSH) are used to index the majority of databases generated by the National Library of Medicine. Essentially, MeSH terms are designed to make information, such as scientific articles, more retrievable and assessable to users of systems such as PubMed. This paper proposes a novel method for automating the assignment of biomedical publications with MeSH terms that takes advantage of citation references to these publications. Our findings show that analysing the citation references that point to a document can provide a useful source of terms that are not present in the document. The use of these citation contexts, as they are known, can thus help to provide a richer document feature representation, which in turn can help improve text mining and information retrieval applications, in our case MeSH term classification. In this paper, we also explore new methods of selecting and utilising citation contexts. In particular, we assess the effect of weighting the importance of citation terms (found in the citation contexts) according to two aspects: (i) the section of the paper they appear in and (ii) their distance to the citation marker. We conduct intrinsic and extrinsic evaluations of citation term quality. For the intrinsic evaluation, we rely on the UMLS Metathesaurus conceptual database to explore the semantic characteristics of the mined citation terms. We also analyse the "informativeness" of these terms using a class-entropy measure. For the extrinsic evaluation, we run a series of automatic document classification experiments over MeSH terms. Our experimental evaluation shows that citation contexts contain terms that are related to the original document, and that the integration of this knowledge results in better classification performance compared to two state-of-the-art MeSH classification systems: MeSHUP and MTI. Our experiments also demonstrate that the consideration of Section and Distance factors can lead to statistically

Comparing Medline citations using modified N-grams

Nawab, Rao Muhammad Adeel; Stevenson, Mark; Clough, Paul

2014-01-01

Objective We aim to identify duplicate pairs of Medline citations, particularly when the documents are not identical but contain similar information. Materials and methods Duplicate pairs of citations are identified by comparing word n-grams in pairs of documents. N-grams are modified using two approaches which take account of the fact that the document may have been altered. These are: (1) deletion, an item in the n-gram is removed; and (2) substitution, an item in the n-gram is substituted with a similar term obtained from the Unified Medical Language System  Metathesaurus. N-grams are also weighted using a score derived from a language model. Evaluation is carried out using a set of 520 Medline citation pairs, including a set of 260 manually verified duplicate pairs obtained from the Deja Vu database. Results The approach accurately detects duplicate Medline document pairs with an F1 measure score of 0.99. Allowing for word deletions and substitution improves performance. The best results are obtained by combining scores for n-grams of length 1–5 words. Discussion Results show that the detection of duplicate Medline citations can be improved by modifying n-grams and that high performance can also be obtained using only unigrams (F1=0.959), particularly when allowing for substitutions of alternative phrases.

Characterizing and modeling citation dynamics.

Young-Ho Eom

Full Text Available Citation distributions are crucial for the analysis and modeling of the activity of scientists. We investigated bibliometric data of papers published in journals of the American Physical Society, searching for the type of function which best describes the observed citation distributions. We used the goodness of fit with Kolmogorov-Smirnov statistics for three classes of functions: log-normal, simple power law and shifted power law. The shifted power law turns out to be the most reliable hypothesis for all citation networks we derived, which correspond to different time spans. We find that citation dynamics is characterized by bursts, usually occurring within a few years since publication of a paper, and the burst size spans several orders of magnitude. We also investigated the microscopic mechanisms for the evolution of citation networks, by proposing a linear preferential attachment with time dependent initial attractiveness. The model successfully reproduces the empirical citation distributions and accounts for the presence of citation bursts as well.

Identifying Anomalous Citations for Objective Evaluation of Scholarly Article Impact.

Directory of Open Access Journals (Sweden)

Xiaomei Bai

Full Text Available Evaluating the impact of a scholarly article is of great significance and has attracted great attentions. Although citation-based evaluation approaches have been widely used, these approaches face limitations e.g. in identifying anomalous citations patterns. This negligence would inevitably cause unfairness and inaccuracy to the article impact evaluation. In this study, in order to discover the anomalous citations and ensure the fairness and accuracy of research outcome evaluation, we investigate the citation relationships between articles using the following factors: collaboration times, the time span of collaboration, citing times and the time span of citing to weaken the relationship of Conflict of Interest (COI in the citation network. Meanwhile, we study a special kind of COI, namely suspected COI relationship. Based on the COI relationship, we further bring forward the COIRank algorithm, an innovative scheme for accurately assessing the impact of an article. Our method distinguishes the citation strength, and utilizes PageRank and HITS algorithms to rank scholarly articles comprehensively. The experiments are conducted on the American Physical Society (APS dataset. We find that about 80.88% articles contain contributed citations by co-authors in 26,366 articles and 75.55% articles among these articles are cited by the authors belonging to the same affiliation, indicating COI and suspected COI should not be ignored for evaluating impact of scientific papers objectively. Moreover, our experimental results demonstrate COIRank algorithm significantly outperforms the state-of-art solutions. The validity of our approach is verified by using the probability of Recommendation Intensity.

Invenio is the web-based integrated digital library system developed at CERN. Within this framework, we present four types of ranking models based on the citation graph that complement the simple approach based on citation counts: time-dependent citation counts, a relevancy ranking which extends the PageRank model, a time-dependent ranking which combines the freshness of citations with PageRank and a ranking that takes into consideration the external citations. We present our analysis and results obtained on two main data sets: Inspire and CERN Document Server. Our main contributions are: (i) a study of the currently available ranking methods based on the citation graph; (ii) the development of new ranking methods that correct some of the identified limitations of the current methods such as treating all citations of equal importance, not taking time into account or considering the citation graph complete; (iii) a detailed study of the key parameters for these ranking methods.

Findings present current thinking on the conversion of a dissertation into a journal paper in terms of how dissertations differ from journal articles, reframing for publication, rethinking the material, trimming the length, time taken to rewrite the material, specific lessons, and adapting for publication. Recommendations provided in the paper will enable staff to take this course of action when developing their publication portfolio to become more research active and to make an important contribution to the publication output of their department/school/faculty, especially with regard to assessment exercises such as the Research Excellence Framework. The value of the paper is that by following appropriate approaches, processes, and procedures it is possible to convert a good dissertation into a ranked journal article.

Modeling the citation network by network cosmology.

Xie, Zheng; Ouyang, Zhenzheng; Zhang, Pengyuan; Yi, Dongyun; Kong, Dexing

Citation between papers can be treated as a causal relationship. In addition, some citation networks have a number of similarities to the causal networks in network cosmology, e.g., the similar in-and out-degree distributions. Hence, it is possible to model the citation network using network cosmology. The casual network models built on homogenous spacetimes have some restrictions when describing some phenomena in citation networks, e.g., the hot papers receive more citations than other simultaneously published papers. We propose an inhomogenous causal network model to model the citation network, the connection mechanism of which well expresses some features of citation. The node growth trend and degree distributions of the generated networks also fit those of some citation networks well.

The German medical dissertation--time to change?

Science.gov (United States)

Diez, C; Arkenau, C; Meyer-Wentrup, F

2000-08-01

German medical students must conduct a research project and write a dissertation in order to receive the title "Doctor." However, the dissertation is not required to graduate, enter a residency, or practice medicine. About 90% of practicing physicians hold the title "Doctor"; a career in academic medicine almost always requires it. Although no convincing evidence supports the usefulness of the dissertation, many regard its completion as important to maintaining a high level of scientific competence and patient care. In recent years, the number of successfully completed dissertations has declined. Lack of time during medical school, the perceived irrelevance of the dissertation to medical practice, and the poor design of many projects may be at least part of the problem. There is also increasing evidence that conducting research frequently delays graduation and may affect clinical skills because students working on projects attend fewer classes, ward rounds, and clinical tutorials and do not spent sufficient time preparing for examinations. The scientific value of students' research has also been criticized; critics point out that students do not have enough time or experience to critically analyze methods and data, and they often are not properly supervised. European unification will probably lead to standardized requirements for medical education and research. The authors hope this will eliminate the dissertation requirement in Germany.

Citation analysis of the scientific publications of Britton Chance in ISI citation indexes

Directory of Open Access Journals (Sweden)

Lin Z. Li

2014-03-01

Full Text Available Britton Chance was a pioneer in many scientific fields such as enzymatic reaction kinetics, bioenergetics, metabolism, in vivo NMR, and biophotonics. As an engineer, physical chemist, physicist, physiologist, biophysicist, biochemist, innovator and educator, he had worked in diversified fields over extended periods between 1926 until his death in 2010, at the age of 97. In order to illustrate his scientific career and great impact on research from a new perspective, we employ scientometric analysis tools to analyze the publications of Britton Chance with data downloaded from the ISI Citation Indexes in April 2013. We included articles, reviews and proceeding papers but excluded meeting abstracts. In total, we obtained 1023 publication records with 1236 authors in 266 journals with 17,114 citations from 1945 to 2013. We show the annual publications and citations that Britton Chance received from 1945 to 2013, and generate HistCite maps on the basis of the global citations (GCS and local (self citations (LCS to show the citation relationships among the top-30 publications of Britton Chance. Metabolism and the development of physical methods to probe it appear to be the connecting thread of the lifelong research of Britton Chance. Furthermore, we generate the journal map and co-authorship map to show the broad scope of research topics and collaborators and the high impacts of the scientific oeuvre of Britton Chance ranging from physics, engineering, chemistry and biology to medicine.

Gender Differences in Synchronous and Diachronous Self-citations

Energy Technology Data Exchange (ETDEWEB)

Ghiasi, G.; Lariviere, V.; Sugimoto, C.

2016-07-01

Citation rates are increasingly used as a currency of science, providing a basis to reward a scientist. Self-citations, an inevitable part of scholarly communication, may contribute to the inflation of citation counts and impose a considerable impact on research evaluation and academic career advancements. Self-citations are classified into two types in this study: synchronous self-citations (self-citations an author gives) and diachronous self-citations (selfcitations an author receives). The main objective of this paper is to provide a comprehensive gendered analysis of synchronous and diachronous self-citations across all scientific disciplines. For this purpose, citation data of 12,725,171 articles published in 2008-2014 are extracted from Web of Science and are further scrutinized for articles of each gender. The findings reveal that men receive citations from their own papers at a higher rate than their women counterparts. They also tend to give more citations to their own publications. Gender gap in citation impact decreases when first-author’s diachronous citations are eliminated in the impact analysis. However, the gap does not vary when all-authors’ diachronous citations are excluded. The results of this research is important for effective gender-related policy-making in the science and technology arena. (Author)

The citation climate in neurosurgical literature is largely undefined. To study the patterns of citation of articles in neurosurgery as a scientific field and to evaluate the performance of neurosurgery journals vis-à-vis journals in other fields. References cited in articles published in neurosurgery journals during a specified time period were analyzed to determine the age of articles cited in neurosurgical literature. In the next analysis, articles published in neurosurgical journals were followed up for 13 years after publication. The postpublication citation patterns were analyzed to determine the time taken to reach the maximally cited state and the time when articles stopped being cited. The final part of the study dealt with the evolution of a new interfield citation metric, which was then compared with other standardized citation indexes. The mean ± SD age of articles cited in neurosurgical literature was 11.6 ± 11.7 years (median, 8 years). Citations received by articles gradually increased to a peak (at 6.25 years after publication in neurosurgery) and then reached a steady state; articles were still cited well into the late postpublication period. Neurosurgical articles published in nonneurosurgical high-impact journals were cited more highly than those in neurosurgical journals, although they took approximately the same time to reach the maximally cited state (7.2 years). The most cited pure neurosurgery journal was Neurosurgery. The citation climate for neurosurgery was adequately described. The interfield citation metric was able to ensure cross-field comparability of journal performance. G1, group 1G2, group 2G3, group 3G4, group 4IFCM, interfield citation metric.

Patent citation network in nanotechnology (1976-2004)

The patent citation networks are described using critical node, core network, and network topological analysis. The main objective is understanding of the knowledge transfer processes between technical fields, institutions and countries. This includes identifying key influential players and subfields, the knowledge transfer patterns among them, and the overall knowledge transfer efficiency. The proposed framework is applied to the field of nanoscale science and engineering (NSE), including the citation networks of patent documents, submitting institutions, technology fields, and countries. The NSE patents were identified by keywords 'full-text' searching of patents at the United States Patent and Trademark Office (USPTO). The analysis shows that the United States is the most important citation center in NSE research. The institution citation network illustrates a more efficient knowledge transfer between institutions than a random network. The country citation network displays a knowledge transfer capability as efficient as a random network. The technology field citation network and the patent document citation network exhibit a less efficient knowledge diffusion capability than a random network. All four citation networks show a tendency to form local citation clusters

CMIP6 Data Citation of Evolving Data

Directory of Open Access Journals (Sweden)

Martina Stockhause

2017-06-01

Full Text Available Data citations have become widely accepted. Technical infrastructures as well as principles and recommendations for data citation are in place but best practices or guidelines for their implementation are not yet available. On the other hand, the scientific climate community requests early citations on evolving data for credit, e.g. for CMIP6 (Coupled Model Intercomparison Project Phase 6. The data citation concept for CMIP6 is presented. The main challenges lie in limited resources, a strict project timeline and the dependency on changes of the data dissemination infrastructure ESGF (Earth System Grid Federation to meet the data citation requirements. Therefore a pragmatic, flexible and extendible approach for the CMIP6 data citation service was developed, consisting of a citation for the full evolving data superset and a data cart approach for citing the concrete used data subset. This two citation approach can be implemented according to the RDA recommendations for evolving data. Because of resource constraints and missing project policies, the implementation of the second part of the citation concept is postponed to CMIP7.

Tense Usage in Selected Humanities and Science Dissertations

Directory of Open Access Journals (Sweden)

Geoffrey M. Maroko

2014-11-01

Full Text Available Abstract Graduate students are usually not sure of the appropriate tense to use in each rhetorical section of their dissertations in their disciplines. Even style guides provide little information regarding tense usage in academic texts. This paper describes a study in which frequency and usage of types of tense were compared in selected dissertations from the humanities and sciences drawn from Kenyan Public Universities. It was found that graduate research students in both humanities and sciences preferred the simple present and simple past as primary tense forms. It also emerged that authors have to alternate verb tenses even in the same rhetorical section of a dissertation to achieve particular communicative purposes. Suggesting that choices for tense in dissertations are a function of the epistemology and ideology of the disciplines, the paper proposes a genre-based approach to teaching those preparing to write their dissertations.

The comparative importance of books: clinical psychology in the health sciences library.

Science.gov (United States)

Wehmeyer, J M; Wehmeyer, S

1999-01-01

Clinical psychology has received little attention as a subject in health sciences library collections. This study seeks to demonstrate the relative importance of the monographic literature to clinical psychology through the examination of citations in graduate student theses and dissertations at the Fordham Health Sciences Library, Wright State University. Dissertations and theses were sampled randomly; citations were classified by format, counted, and subjected to statistical analysis. Books and book chapters together account for 35% of the citations in clinical psychology dissertations, 25% in nursing theses, and 8% in biomedical sciences theses and dissertations. Analysis of variance indicates that the citations in dissertations and theses in the three areas differ significantly (F = 162.2 with 2 and 253 degrees of freedom, P = 0.0001). Dissertations and theses in biomedical sciences and nursing theses both cite significantly more journals per book than the dissertations in clinical psychology. These results support the hypothesis that users of clinical psychology literature rely more heavily on books than many other users of a health sciences library. Problems with using citation analyses in a single subject to determine a serials to monographs ratio for a health sciences library are pointed out. PMID:10219478

2013-01-01

Full Text Available BACKGROUND: The impact of a scientific article is proportional to the citations it has received. In this study, we set out to identify the most cited works in epileptology in order to evaluate research trends in this field. METHODS: According to the Web of Science database, articles with more than 400 citations qualify as "citation classics". We conducted a literature search on the ISI Web of Science bibliometric database for scientific articles relevant to epilepsy. RESULTS: We retrieved 67 highly cited articles (400 or more citations, which were published in 31 journals: 17 clinical studies, 42 laboratory studies, 5 reviews and 3 classification articles. Clinical studies consisted of epidemiological analyses (n=3, studies on the clinical phenomenology of epilepsy (n=5 – including behavioral and prognostic aspects – and articles focusing on pharmacological (n=6 and non-pharmacological (n=3 treatment. The laboratory studies dealt with genetics (n=6, animal models (n=27, and neurobiology (n=9 – including both neurophysiology and neuropathology studies. The majority (61% of citation classics on epilepsy were published after 1986, possibly reflecting the expansion of research interest in laboratory studies driven by the development of new methodologies, specifically in the fields of genetics and animal models. Consequently, clinical studies were highly cited both before and after the mid 80s, whilst laboratory researches became widely cited after 1990. CONCLUSIONS: Our study indicates that the main drivers of scientific impact in the field of epileptology have increasingly become genetic and neurobiological studies, along with research on animal models of epilepsy. These articles are able to gain the highest numbers of citations in the time span of a few years and suggest potential directions for future research.

Incites into Citation Linking using the OAI-PMH

CERN Multimedia

CERN. Geneva

2005-01-01

There are some 300 repositories of research material (Source: IAR), most of which have an OAI-PMH interface, but no current Institutional Repositories export reference data - nor do they provide their users with citation impact metrics. We propose a model for extending IR's to be citation aware and to expose that data to citation indices using the OAI-PMH and OpenURL. We present some techniques for the export of citation data using the OAI-PMH in Citebase Search. As part of a proposed Open Access Citation Information study we have developed a proposal for the integration of reference parsing and linking into the author- deposit process. This highly-distributed approach to citation linking utilises the OAI-PMH to transfer structured citation data between IRs and citation indexing services. OpenURL - a standard for contextual linking using bibliographic data - is now a NISO standard. As well as it's linking role, OpenURL is a useful standard for the transfer of bibliographic data for the purposes of citation in...

Using incomplete citation data for MEDLINE results ranking.

Science.gov (United States)

Herskovic, Jorge R; Bernstam, Elmer V

2005-01-01

Information overload is a significant problem for modern medicine. Searching MEDLINE for common topics often retrieves more relevant documents than users can review. Therefore, we must identify documents that are not only relevant, but also important. Our system ranks articles using citation counts and the PageRank algorithm, incorporating data from the Science Citation Index. However, citation data is usually incomplete. Therefore, we explore the relationship between the quantity of citation information available to the system and the quality of the result ranking. Specifically, we test the ability of citation count and PageRank to identify "important articles" as defined by experts from large result sets with decreasing citation information. We found that PageRank performs better than simple citation counts, but both algorithms are surprisingly robust to information loss. We conclude that even an incomplete citation database is likely to be effective for importance ranking.

Kamel, Mohamed; Terasaki, Yusuke; Adusumilli, Prasad S; Stiles, Brendon M

2016-01-01

We examined the impact of work presented in the plenary sessions at the meeting of The American Association for Thoracic Surgery (AATS), by determining how frequently the published papers corresponding to the session presentations during the past 20 years, were cited; those that were most cited were identified. We reviewed the AATS meeting programs from the 20-year period from 1994 to 2014 and identified the corresponding publications in the Journal of Thoracic and Cardiovascular Surgery (JTCVS) from all abstracts presented at the plenary sessions. Papers were categorized as cardiac, thoracic, or congenital. References were evaluated for subsequent citation in the Web of Science (WoS), and Google Scholar (GS). We determined both the median number of citations overall, and per year. For comparison, we evaluated numbers of citations in WoS from current JTCVS papers in issues containing the 3 most-cited plenary session papers. Among 195 published plenary papers, the median number of citations in WoS and GS was 49 and 76, respectively. The median total number of citations in WoS was as follows: 51 for cardiac-category papers (n = 105); 61 for thoracic (n = 55), and 41 for congenital (n = 35). These values were higher than the median total number of citations for contemporary nonplenary JTCVS papers: cardiac (22, n = 55; P papers published in JTCVS. The median number of citations per year since publication for plenary publications was 5.9 (cardiac), 6 (thoracic), and 3.7 (congenital), respectively. Publications corresponding to the plenary sessions of the AATS are highly cited and include some of the seminal studies in our field in the past 20 years.

Xu, Jun; Zhang, Yaoyun; Wu, Yonghui; Wang, Jingqi; Dong, Xiao; Xu, Hua

2015-01-01

In scientific writing, positive credits and negative criticisms can often be seen in the text mentioning the cited papers, providing useful information about whether a study can be reproduced or not. In this study, we focus on citation sentiment analysis, which aims to determine the sentiment polarity that the citation context carries towards the cited paper. A citation sentiment corpus was annotated first on clinical trial papers. The effectiveness of n-gram and sentiment lexicon features, and problem-specified structure features for citation sentiment analysis were then examined using the annotated corpus. The combined features from the word n-grams, the sentiment lexicons and the structure information achieved the highest Micro F-score of 0.860 and Macro-F score of 0.719, indicating that it is feasible to use machine learning methods for citation sentiment analysis in biomedical publications. A comprehensive comparison between citation sentiment analysis of clinical trial papers and other general domains were conducted, which additionally highlights the unique challenges within this domain.

Citation Matching in Sanskrit Corpora Using Local Alignment

Science.gov (United States)

Prasad, Abhinandan S.; Rao, Shrisha

Citation matching is the problem of finding which citation occurs in a given textual corpus. Most existing citation matching work is done on scientific literature. The goal of this paper is to present methods for performing citation matching on Sanskrit texts. Exact matching and approximate matching are the two methods for performing citation matching. The exact matching method checks for exact occurrence of the citation with respect to the textual corpus. Approximate matching is a fuzzy string-matching method which computes a similarity score between an individual line of the textual corpus and the citation. The Smith-Waterman-Gotoh algorithm for local alignment, which is generally used in bioinformatics, is used here for calculating the similarity score. This similarity score is a measure of the closeness between the text and the citation. The exact- and approximate-matching methods are evaluated and compared. The methods presented can be easily applied to corpora in other Indic languages like Kannada, Tamil, etc. The approximate-matching method can in particular be used in the compilation of critical editions and plagiarism detection in a literary work.

Data citation is of growing concern for owners of curated databases, who wish to give credit to the contributors and curators responsible for portions of the dataset and enable the data retrieved by a query to be later examined. While several databases specify how data should be cited, they leave it to users to manually construct the citations and do not generate them automatically. We report our experiences in automating data citation for an RDF dataset called eagle-i, and discuss how to generalize this to a citation framework that can work across a variety of different types of databases (e.g. relational, XML, and RDF). We also describe how a database administrator would use this framework to automate citation for a particular dataset.

Universality of Citation Distributions for Academic Institutions and Journals

Science.gov (United States)

Chatterjee, Arnab; Ghosh, Asim; Chakrabarti, Bikas K.

2016-01-01

Citations measure the importance of a publication, and may serve as a proxy for its popularity and quality of its contents. Here we study the distributions of citations to publications from individual academic institutions for a single year. The average number of citations have large variations between different institutions across the world, but the probability distributions of citations for individual institutions can be rescaled to a common form by scaling the citations by the average number of citations for that institution. We find this feature seems to be universal for a broad selection of institutions irrespective of the average number of citations per article. A similar analysis for citations to publications in a particular journal in a single year reveals similar results. We find high absolute inequality for both these sets, Gini coefficients being around 0.66 and 0.58 for institutions and journals respectively. We also find that the top 25% of the articles hold about 75% of the total citations for institutions and the top 29% of the articles hold about 71% of the total citations for journals. PMID:26751563

Measures of research productivity are increasingly used to determine how research should be evaluated and funding decisions made. In psychiatry, citation patterns within and between countries are not known, and whether these differ by choice of citation metric. In this study, we examined publication characteristics and citation practices in articles published in 50 Web of Science indexed psychiatric and relevant clinical neurosciences journals, between January 2004 and December 2009 comprising 51,072 records that produced 375,962 citations. We compared citation patterns, including self-citations, between countries using standard x(2) tests. We found that most publications came from the USA, with Germany being second and UK third in productivity. USA articles received most citations and the highest citation rate with an average 11.5 citations per article. The UK received the second highest absolute number of citations, but came fourth by citation rate (9.7 citations/article), after the Netherlands (11.4 citations/article) and Canada (9.8 citations/article). Within the USA, Harvard University published most articles and these articles were the most cited, on average 20.0 citations per paper. In Europe, UK institutions published and were cited most often. The Institute of Psychiatry/Kings College London was the leading institution in terms of number of published records and overall citations, while Oxford University had the highest citation rate (18.5 citations/record). There were no differences between the self-citation practices of American and European researchers. Articles that examined some aspect of treatment in psychiatry were the most published. In terms of diagnosis, papers about schizophrenia-spectrum disorders were the most published and the most cited. We found large differences between and within countries in terms of their research productivity in psychiatry and clinical neuroscience. In addition, the ranking of countries and institutions differed widely

Doctoral Dissertation Topics in Education: Do They Align with Critical Issues?

Directory of Open Access Journals (Sweden)

Ethan J Allen

2016-11-01

Full Text Available American society faces complex educational issues which impact many facets of its national interests. Institutions of higher education are granting doctoral degrees to educational leaders, but it is not known to what extent their dissertation topics are aligned with both longstanding and critical issues in education. Using a theoretical framework synthesizing Paul and Elder’s critical thinking model and Kuhlthau’s information seeking process, this study examines a set of education doctoral dissertation topical selections and categorizes them by general themes in relationship to many of the recognized educational issues in the United States. Investigators categorized dissertations from four departments within the College of Education of their home institution. The dataset, retrieved from ProQuest Dissertations and Theses Global, consisted of 231 documents published between 2005 and 2014. Through an inter-rater process examining dissertation titles, abstracts, and keywords, the dissertations were assigned critical issue themes culled from nine editions of a college text, and then categorized under a broader topical scheme situated within a well-used educational research website. Findings indicated that most dissertations concentrated in studies that researched problems and issues within schools. Further, some of the issues considered longstanding were not studied by dissertation authors within the sample. For example, privatization of schools and classroom discipline and justice were not selected for study. Findings also suggest new directions for those responsible for dissertation supervision and topic selection. The study adds to the literature on dissertation topic selection that addresses existing educational issues.

Miri, Seyyed Mohammad; Raoofi, Azam; Heidari, Zahra

2012-09-01

Citation analysis as one of the most widely used methods of bibliometrics can be used for computing the various impact measures for scholars based on data from citation databases. Journal Citation Reports (JCR) from Thomson Reuters provides annual report in the form of impact factor (IF) for each journal. We aimed to evaluate the citation parameters of Hepatitis Monthly by JCR in 2010 and compare them with GS and Sc. All articles of Hepat Mon published in 2009 and 2008 which had been cited in 2010 in three databases including WoS, Sc and GS gathered in a spreadsheet. The IFs were manually calculated. Among the 104 total published articles the accuracy rates of GS and Sc in recording the total number of articles was 96% and 87.5%. There was a difference between IFs among the three databases (0.793 in ISI [Institute for Scientific Information], 0.945 in Sc and 0.85 GS). The missing rate of citations in ISI was 4% totally. Original articles were the main cited types, whereas, guidelines and clinical challenges were the least ones. None of the three databases succeed to record all articles published in the journal. Despite high sensitivity of GS comparing to Sc, it cannot be a reliable source for indexing since GS has lack of screening in the data collection and low specificity. Using an average of three IFs is suggested to find the correct IF. Editors should be more aware on the role of original articles in increasing IF and the potential efficacy of review articles in long term impact factor.

From Excessive Journal Self-Cites to Citation Stacking: Analysis of Journal Self-Citation Kinetics in Search for Journals, Which Boost Their Scientometric Indicators.

Science.gov (United States)

Heneberg, Petr

2016-01-01

Bibliometric indicators increasingly affect careers, funding, and reputation of individuals, their institutions and journals themselves. In contrast to author self-citations, little is known about kinetics of journal self-citations. Here we hypothesized that they may show a generalizable pattern within particular research fields or across multiple fields. We thus analyzed self-cites to 60 journals from three research fields (multidisciplinary sciences, parasitology, and information science). We also hypothesized that the kinetics of journal self-citations and citations received from other journals of the same publisher may differ from foreign citations. We analyzed the journals published the American Association for the Advancement of Science, Nature Publishing Group, and Editura Academiei Române. We found that although the kinetics of journal self-cites is generally faster compared to foreign cites, it shows some field-specific characteristics. Particularly in information science journals, the initial increase in a share of journal self-citations during post-publication year 0 was completely absent. Self-promoting journal self-citations of top-tier journals have rather indirect but negligible direct effects on bibliometric indicators, affecting just the immediacy index and marginally increasing the impact factor itself as long as the affected journals are well established in their fields. In contrast, other forms of journal self-citations and citation stacking may severely affect the impact factor, or other citation-based indices. We identified here a network consisting of three Romanian physics journals Proceedings of the Romanian Academy, Series A, Romanian Journal of Physics, and Romanian Reports in Physics, which displayed low to moderate ratio of journal self-citations, but which multiplied recently their impact factors, and were mutually responsible for 55.9%, 64.7% and 63.3% of citations within the impact factor calculation window to the three journals

To determine whether algorithms developed for the World Wide Web can be applied to the biomedical literature in order to identify articles that are important as well as relevant. DESIGN AND MEASUREMENTS A direct comparison of eight algorithms: simple PubMed queries, clinical queries (sensitive and specific versions), vector cosine comparison, citation count, journal impact factor, PageRank, and machine learning based on polynomial support vector machines. The objective was to prioritize important articles, defined as being included in a pre-existing bibliography of important literature in surgical oncology. RESULTS Citation-based algorithms were more effective than noncitation-based algorithms at identifying important articles. The most effective strategies were simple citation count and PageRank, which on average identified over six important articles in the first 100 results compared to 0.85 for the best noncitation-based algorithm (p PageRank more than simple citation count. However, in spite of citation lag, citation-based algorithms remain more effective than noncitation-based algorithms. CONCLUSION Algorithms that have proved successful on the World Wide Web can be applied to biomedical information retrieval. Citation-based algorithms can help identify important articles within large sets of relevant results. Further studies are needed to determine whether citation-based algorithms can effectively meet actual user information needs.

Power-law citation distributions are not scale-free.

Science.gov (United States)

Golosovsky, Michael

2017-09-01

We analyze time evolution of statistical distributions of citations to scientific papers published in the same year. While these distributions seem to follow the power-law dependence we find that they are nonstationary and the exponent of the power-law fit decreases with time and does not come to saturation. We attribute the nonstationarity of citation distributions to different longevity of the low-cited and highly cited papers. By measuring citation trajectories of papers we found that citation careers of the low-cited papers come to saturation after 10-15 years while those of the highly cited papers continue to increase indefinitely: The papers that exceed some citation threshold become runaways. Thus, we show that although citation distribution can look as a power-law dependence, it is not scale free and there is a hidden dynamic scale associated with the onset of runaways. We compare our measurements to our recently developed model of citation dynamics based on copying-redirection-triadic closure and find explanations to our empirical observations.

We describe here an improved method to quantify the influence of a research article by making novel use of its co-citation network to field-normalize the number of citations it has received. Article citation rates are divided by an expected citation rate that is derived from performance of articles in the same field and benchmarked to a peer comparison group. The resulting Relative Citation Ratio is article level and field independent and provides an alternative to the invalid practice of using journal impact factors to identify influential papers. To illustrate one application of our method, we analyzed 88,835 articles published between 2003 and 2010 and found that the National Institutes of Health awardees who authored those papers occupy relatively stable positions of influence across all disciplines. We demonstrate that the values generated by this method strongly correlate with the opinions of subject matter experts in biomedical research and suggest that the same approach should be generally applicable to articles published in all areas of science.

Towards a simple mathematical theory of citation distributions.

Science.gov (United States)

Katchanov, Yurij L

2015-01-01

The paper is written with the assumption that the purpose of a mathematical theory of citation is to explain bibliometric regularities at the level of mathematical formalism. A mathematical formalism is proposed for the appearance of power law distributions in social citation systems. The principal contributions of this paper are an axiomatic characterization of citation distributions in terms of the Ekeland variational principle and a mathematical exploration of the power law nature of citation distributions. Apart from its inherent value in providing a better understanding of the mathematical underpinnings of bibliometric models, such an approach can be used to derive a citation distribution from first principles.

Neuroscience and molecular biology have been generating large datasets over the past years that are reshaping how research is being conducted. In their wake, open data sharing has been singled out as a major challenge for the future of research. We conducted a comparative study of citations of data publications in both fields, showing that the average publication tagged with a data-related term by the NCBI MeSH (Medical Subject Headings) curators achieves a significantly larger citation impact than the average in either field. We introduce a new metric, the data article citation index (DAC-index), to identify the most prolific authors among those data-related publications. The study is fully reproducible from an executable Rmd (R Markdown) script together with all the citation datasets. We hope these results can encourage authors to more openly publish their data.

Impact factors are currently the bibliometric index most used for evaluating scientific journals. However, the way in which they are used, for instance concerning the study or journal types analyzed, can markedly interfere with estimate reliability. This study aimed to analyze the citation distribution pattern in three Brazilian journals of general medicine. This was a descriptive study based on numbers of citations of scientific studies published by three Brazilian journals of general medicine. The journals analyzed were São Paulo Medical Journal, Clinics and Revista da Associação Médica Brasileira. This survey used data available from the Institute for Scientific Information (ISI) platform, from which the total number of papers published in each journal in 2007-2008 and the number of citations of these papers in 2009 were obtained. From these data, the citation distribution was derived and journal impact factors (average number of citations) were estimated. These factors were then compared with those directly available from the ISI Journal of Citation Reports (JCR). Respectively, 134, 203 and 192 papers were published by these journals during the period analyzed. The observed citation distributions were highly skewed, such that many papers had few citations and a small percentage had many citations. It was not possible to identify any specific pattern for the most cited papers or to exactly reproduce the JCR impact factors. Use of measures like "impact factors", which characterize citations through averages, does not adequately represent the citation distribution in the journals analyzed.

This paper defines and discusses two important types of citations, self-citation and mandatory citation, in engineering journals. Citation can be classified in three categories: optional; semi-mandatory; and mandatory. There are some negative and positive impacts for the authors' paper and journals' reputation if mandatory citation of a paper or set of papers is requested. These effects can be different based on the recommended papers for citing in the new research. Mandatory citation has various types discussed in this paper. Self-citation and its reasons and impacts are also discussed in the present study.

Full Text Available Aim: Informal citations is bibliographic information (title or Internet address, citing sources of information resources for informal scholarly communication and always neglected in traditional citation databases. This study is done, in order to answer the question of whether informal citations in the web environment are traceable. The present research aims to determine what proportion of web citations of Google search engine is related to formal and informal citation. Research method: Webometrics is the method used. The study is done on 1344 research articles of 98 open access journal, and the method that is used to extract the web citation from Google search engine is “Web / URL citation extraction". Findings: The findings showed that ten percent of the web citations of Google search engine are formal and informal citations. The highest formal citation in the Google search engine with 19/27% is in the field of library and information science and the lowest official citation by 1/54% is devoted to the field of civil engineering. The highest percentage of informal citations with 3/57% is devoted to sociology and the lowest percentage of informal citations by 0/39% is devoted to the field of civil engineering. Journal Citation is highest with 94/12% in the surgical field and lowest with 5/26 percent in the philosophy filed. Result: Due to formal and informal citations in the Google search engine which is about 10 percent and the reduction of this amount compared to previous research, it seems that track citations by this engine should be treated with more caution. We see that the amount of formal citation is variable in different disciplines. Cited journals in the field of surgery, is highest and in the filed of philosophy is lowest, this indicates that in the filed of philosophy, that is a subset of the social sciences, journals in scientific communication do not play a significant role. On the other hand, book has a key role in this filed

Golembiewski, Elizabeth H; Holmes, Ann M; Jackson, Joanna R; Brown-Podgorski, Brittany L; Menachemi, Nir

Given the call for more interdisciplinary research in public health, the objectives of this study were to (1) examine the correlates of interdisciplinary dissertation completion and (2) identify secondary fields most common among interdisciplinary public health graduates. We analyzed pooled cross-sectional data from 11 120 doctoral graduates in the Survey of Earned Doctorates, 2003-2015. The primary outcome was interdisciplinary dissertation completion. Covariates included primary public health field, sociodemographic characteristics, and institutional attributes. From 2003 to 2015, a total of 4005 of 11 120 (36.0%) doctoral graduates in public health reported interdisciplinary dissertations, with significant increases observed in recent years. Compared with general public health graduates, graduates of environmental health (odds ratio [OR] = 1.74; P dissertation work, whereas graduates from biostatistics (OR = 0.51; P dissertation was associated with being male, a non-US citizen, a graduate of a private institution, and a graduate of an institution with high but not the highest level of research activity. Many secondary dissertation fields reported by interdisciplinary graduates included other public health fields. Although interdisciplinary dissertation research among doctoral graduates in public health has increased in recent years, such work is bounded in certain fields of public health and certain types of graduates and institutions. Academic administrators and other stakeholders may use these results to inform greater interdisciplinary activity during doctoral training and to evaluate current and future collaborations across departments or schools.

Multiple Citation Indicators and Their Composite across Scientific Disciplines.

Ioannidis, John P A; Klavans, Richard; Boyack, Kevin W

2016-07-01

Many fields face an increasing prevalence of multi-authorship, and this poses challenges in assessing citation metrics. Here, we explore multiple citation indicators that address total impact (number of citations, Hirsch H index [H]), co-authorship adjustment (Schreiber Hm index [Hm]), and author order (total citations to papers as single; single or first; or single, first, or last author). We demonstrate the correlation patterns between these indicators across 84,116 scientists (those among the top 30,000 for impact in a single year [2013] in at least one of these indicators) and separately across 12 scientific fields. Correlation patterns vary across these 12 fields. In physics, total citations are highly negatively correlated with indicators of co-authorship adjustment and of author order, while in other sciences the negative correlation is seen only for total citation impact and citations to papers as single author. We propose a composite score that sums standardized values of these six log-transformed indicators. Of the 1,000 top-ranked scientists with the composite score, only 322 are in the top 1,000 based on total citations. Many Nobel laureates and other extremely influential scientists rank among the top-1,000 with the composite indicator, but would rank much lower based on total citations. Conversely, many of the top 1,000 authors on total citations have had no single/first/last-authored cited paper. More Nobel laureates of 2011-2015 are among the top authors when authors are ranked by the composite score than by total citations, H index, or Hm index; 40/47 of these laureates are among the top 30,000 by at least one of the six indicators. We also explore the sensitivity of indicators to self-citation and alphabetic ordering of authors in papers across different scientific fields. Multiple indicators and their composite may give a more comprehensive picture of impact, although no citation indicator, single or composite, can be expected to select all the

Research ethics in dissertations: ethical issues and complexity of reasoning.

Kjellström, S; Ross, S N; Fridlund, B

2010-07-01

Conducting ethically sound research is a fundamental principle of scientific inquiry. Recent research has indicated that ethical concerns are insufficiently dealt with in dissertations. To examine which research ethical topics were addressed and how these were presented in terms of complexity of reasoning in Swedish nurses' dissertations. Analyses of ethical content and complexity of ethical reasoning were performed on 64 Swedish nurses' PhD dissertations dated 2007. A total of seven ethical topics were identified: ethical approval (94% of the dissertations), information and informed consent (86%), confidentiality (67%), ethical aspects of methods (61%), use of ethical principles and regulations (39%), rationale for the study (20%) and fair participant selection (14%). Four of those of topics were most frequently addressed: the majority of dissertations (72%) included 3-5 issues. While many ethical concerns, by their nature, involve systematic concepts or metasystematic principles, ethical reasoning scored predominantly at lesser levels of complexity: abstract (6% of the dissertations), formal (84%) and systematic (10%). Research ethics are inadequately covered in most dissertations by nurses in Sweden. Important ethical concerns are missing, and the complexity of reasoning on ethical principles, motives and implications is insufficient. This is partly due to traditions and norms that discount ethical concerns but is probably also a reflection of the ability of PhD students and supervisors to handle complexity in general. It is suggested that the importance of ethical considerations should be emphasised in graduate and post-graduate studies and that individuals with capacity to deal with systematic and metasystematic concepts are recruited to senior research positions.

Piorun, Mary; Palmer, Lisa A.

2008-01-01

Objective: This paper describes the Lamar Soutter Library's process and costs associated with digitizing 300 doctoral dissertations for a newly implemented institutional repository at the University of Massachusetts Medical School. Methodology: Project tasks included identifying metadata elements, obtaining and tracking permissions, converting the dissertations to an electronic format, and coordinating workflow between library departments. Each dissertation was scanned, reviewed for quality control, enhanced with a table of contents, processed through an optical character recognition function, and added to the institutional repository. Results: Three hundred and twenty dissertations were digitized and added to the repository for a cost of $23,562, or $0.28 per page. Seventy-four percent of the authors who were contacted (n = 282) granted permission to digitize their dissertations. Processing time per title was 170 minutes, for a total processing time of 906 hours. In the first 17 months, full-text dissertations in the collection were downloaded 17,555 times. Conclusion: Locally digitizing dissertations or other scholarly works for inclusion in institutional repositories can be cost effective, especially if small, defined projects are chosen. A successful project serves as an excellent recruitment strategy for the institutional repository and helps libraries build new relationships. Challenges include workflow, cost, policy development, and copyright permissions. PMID:18654648

Chiesa, Alberto; Fazia, Teresa; Bernardinelli, Luisa; Morandi, Gabriella

2017-08-01

We performed a citation analysis of the literature about mindfulness aimed at describing the most significant topics and the impact of more relevant papers. We classified 128 systematic reviews about mindfulness-based intervention retrieved in Scopus according to their object, the population included and the type of mindfulness proposed. The citation counting was reported. The cumulative citation numbers per chronological years and article life were analyzed thorough a linear regression model. 1) We observed a general increase in the number of reviews published from 2003 to 2016; 2) two reviews collected the 33% of the overall citations; 3) citation counting for clinical and mixed population collected the 90% of total citations; 4) clinical reviews had higher cumulative citation per publication/year growth. As mindfulness research advances, higher attention should be given to the mechanisms by which mindfulness interventions work so as to provide fruitful insights for future research.

Silvestre, Jason; Kamath, Atul F

2018-03-01

The h-index is a commonly utilized metric for academic productivity. Previous studies have proposed that self-citation may limit the utility of the h-index. The purpose of this study is to evaluate the impact of self-citation on the h-index among orthopedic investigators. The study cohort consisted of program directors, chairpersons, and faculty at orthopedic surgery residency programs in the United States. The Scopus database was used to determine the h-index and number of citations ± self-citations. The total number of publications was correlated with the change in the h-index via self-citation. A total of 463 researchers were included (198 National Institutes of Health-funded faculty, 147 chairpersons, 118 program directors). Of these researchers, 83.8% cited previous work at least once (mean, 123.9 ± 277.6). Self-citations accounted for 5.8% of all citations. Including these citations increased the author h-index from 18.5 ± 14.9 to 19.2 ± 15.6 (P < .001). A minority of researchers (36.3%, P < .001) had increased their h-index via self-citation (range, 0-11). The proportional increase in the h-index via self-citation was positively related to the number of publications (P < .001). While the practice of self-citation is prevalent in orthopedics, its impact on the h-index is minimal for most researchers. With more publications, researchers can increase their h-index to a greater degree via self-citation.

A Practice and Value Proposal for Doctoral Dissertation Data Curation

Directory of Open Access Journals (Sweden)

W. Aaron Collie

2011-10-01

Full Text Available The preparation and publication of dissertations can be viewed as a subsystem of scholarly communication, and the treatment of data that support doctoral research can be mapped in a very controlled manner to the data curation lifecycle. Dissertation datasets represent “low-hanging fruit” for universities who are developing institutional data collections. The current workflow for processing electronic theses and dissertations (ETD at a typical American university is presented, and a new practice is proposed that includes datasets in the process of formulating, awarding, and disseminating dissertations in a way that enables them to be linked and curated together. The value proposition and new roles for the university and its student-authors, faculty, graduate programs and librarians are explored.

STEM Education Related Dissertation Abstracts: A Bounded Qualitative Meta-study

Science.gov (United States)

Banning, James; Folkestad, James E.

2012-12-01

This article utilizes a bounded qualitative meta-study framework to examine the 101 dissertation abstracts found by searching the ProQuest Dissertation and Theses™ digital database for dissertations abstracts from 1990 through 2010 using the search terms education, science, technology, engineer, and STEM/SMET. Professional search librarians established the search criteria used to establish the database. The overarching research question for this study was: What can we learn from the examination of doctoral dissertations abstracts that focus on the STEM education found from 1990 through 2010? The study's findings provide an overview of doctoral research related to STEM education and the discussion section focuses on quality of abstracts, questions regarding the use of the pipeline metaphor, and location of instructional innovation.

How accessibility influences citation counts: The case of citations to the full text articles available from ResearchGate

2017-08-01

Full Text Available It is generally believed that the number of citations to an article can positively be correlated to its free online availability. In the present study, we investigated the possible impact of academic social networks on the number of citations. We chose the social web service “ResearchGate” as a case. This website acts both as a social network to connect researchers, and at the same time, as an open access repository to publish post-print version of the accepted manuscripts and final versions of open access articles. We collected the data of 1823 articles published by the authors from four different universities. By analyzing these data, we showed that although different levels of full text availability are observed for the four universities, there is always a significant positive correlation between full text availability and the citation count. Moreover, we showed that both post-print version and publisher’s version (i.e., final published version of the archived manuscripts receive more citations than non-OA articles, and the difference in the citation counts of post-print manuscripts and publisher’s version articles is nonsignificant.

Statistical modelling of citation exchange between statistics journals.

Science.gov (United States)

Varin, Cristiano; Cattelan, Manuela; Firth, David

2016-01-01

Rankings of scholarly journals based on citation data are often met with scepticism by the scientific community. Part of the scepticism is due to disparity between the common perception of journals' prestige and their ranking based on citation counts. A more serious concern is the inappropriate use of journal rankings to evaluate the scientific influence of researchers. The paper focuses on analysis of the table of cross-citations among a selection of statistics journals. Data are collected from the Web of Science database published by Thomson Reuters. Our results suggest that modelling the exchange of citations between journals is useful to highlight the most prestigious journals, but also that journal citation data are characterized by considerable heterogeneity, which needs to be properly summarized. Inferential conclusions require care to avoid potential overinterpretation of insignificant differences between journal ratings. Comparison with published ratings of institutions from the UK's research assessment exercise shows strong correlation at aggregate level between assessed research quality and journal citation 'export scores' within the discipline of statistics.

2015-01-01

Peer reviewers sometimes request that authors cite their work, either appropriately or via coercive self-citation to highlight the reviewers' work. The objective of this study was to determine in peer reviews submitted to one biomedical journal (1) the extent of peer reviewer self-citation; (2) the proportion of reviews recommending revision or acceptance versus rejection that included reviewer self-citations; and (3) the proportion of reviewer self-citations versus citations to others that included a rationale. Peer reviews for manuscripts submitted in 2012 to the Journal of Psychosomatic Research were evaluated. Data extraction was performed independently by two investigators. There were 616 peer reviews (526 reviewers; 276 manuscripts), of which 444 recommended revision or acceptance and 172 rejection. Of 428 total citations, there were 122 peer reviewer self-citations (29%) and 306 citations to others' work (71%). Self-citations were more common in reviews recommending revision or acceptance (105 of 316 citations; 33%) versus rejection (17/112; 15%; pcitations with no rationale (26 of 122; 21%) was higher than for citations to others' work (15 of 306; 5%; pcitation in peer reviews is common and may reflect a combination of appropriate citation to research that should be cited in published articles and inappropriate citation intended to highlight the work of the peer reviewer. Providing instructions to peer reviewers about self-citation and asking them to indicate when and why they have self-cited may help to limit self-citation to appropriate, constructive recommendations.

The Anatomy of a Data Citation: Discovery, Reuse, and Credit

Directory of Open Access Journals (Sweden)

Hailey Mooney

2012-05-01

Full Text Available INTRODUCTION Data citation should be a necessary corollary of data publication and reuse. Many researchers are reluctant to share their data, yet they are increasingly encouraged to do just that. Reward structures must be in place to encourage data publication, and citation is the appropriate tool for scholarly acknowledgment. Data citation also allows for the identification, retrieval, replication, and verification of data underlying published studies. METHODS This study examines author behavior and sources of instruction in disciplinary and cultural norms for writing style and citation via a content analysis of journal articles, author instructions, style manuals, and data publishers. Instances of data citation are benchmarked against a Data Citation Adequacy Index. RESULTS Roughly half of journals point toward a style manual that addresses data citation, but the majority of journal articles failed to include an adequate citation to data used in secondary analysis studies. DISCUSSION Full citation of data is not currently a normative behavior in scholarly writing. Multiplicity of data types and lack of awareness regarding existing standards contribute to the problem. CONCLUSION Citations for data must be promoted as an essential component of data publication, sharing, and reuse. Despite confounding factors, librarians and information professionals are well-positioned and should persist in advancing data citation as a normative practice across domains. Doing so promotes a value proposition for data sharing and secondary research broadly, thereby accelerating the pace of scientific research.

2007-01-01

The medicine dissertation is often the last step of a physician's medical studies. Long considered a rite of passage, it is now regarded as a scientific work deserving attention from the national and international scientific community. The objectives of this study were to document the means by which dissertations at the University of Lomé Medical School are diffused and to determine their impact on the scientific production of medical school faculty. This cross-sectional study included all dissertations in medicine at the University of Lomé from 1993 through 2002. We interviewed dissertation supervisors and co-supervisors (questionnaire-structured interviews) and consulted the Medline and CNRS/PASCAL databases, scientific communication registers and local journals to collect information. During this period, 240 dissertations were defended at the University of Lomé medical school. More than half came from the departments of medicine (n=85, 35.4%), surgery (n=57, 23.7%) and paediatrics (n=51, 22.5%). The majority dealt with epidemiological (47 %) and clinical (35.8 %) themes, and only a small minority concerned topics in microbiology and biochemistry (7.5 %). Ninety-nine dissertations (41 %) were published: 54 (22.5%) in indexed journals and 45 (18.5 %) in non-indexed journals; 130 (54%) were delivered as papers or posters at scientific meetings. The distribution of published dissertations according to department showed that the departments of paediatrics (51.3 %), medicine (21.2 %) and surgery (21 %) had the best rates of publication in indexed journals, compared with obstetrics and gynaecology (4 %) and basic science (13.8 %) departments. During the study period, faculty at the University of Lomé medical school published 264 articles in indexed journals: dissertations accounted for only 20.4 %. Dissertations made up a higher proportion of publications in the paediatrics department (32.2 %) than in surgery (20.7 %), medicine (19.8 %), basis sciences (14 %) or

Citation classics in suicide and life threatening behavior: a research note.

Science.gov (United States)

Stack, Steven

2012-12-01

The number of citations a scholarly work receives is a common measure of its impact on the scientific literature; "citation classics" are the most highly cited works. The content of Suicide and Life-Threatening Behavior (SLTB) citation classics is described here. The impact of SLTB citation classics is compared to their counterparts in journals having published the most suicide papers. All data are from the ISI electronic venue on the Web of Science and refer to the number of citations the top 1% of works received in each of ten journals from 1975 through August 10, 2011. Among all ten journals, SLTB ranked first in the number of works on suicide. The principle theme of half of SLTB suicide classics was literature review. The median number of citations for SLTB citation classics (top 1%) was 121.5, with a range between 96 and 279 citations, but classics from generalized psychiatric journals received more citations as anticipated. Journal impact factors explained 73% of the variance in classic's citation counts across journals. On average, suicide classics received 30% more citations than all classics. Among a second group of five specialized suicide journals, however, SLTB ranked first in average 5-year impact. Although SLTB produced the highest number of suicide articles of any journal, SLTB's citation classics received fewer citations than suicide classics in high-impact/prestige, general journals. Future work is needed to assess what predicts which SLTB articles ultimately become citation classics. © 2012 The American Association of Suicidology.

The purpose of this study was to conduct a historical review of psycho-oncology and supportive care research in Canada using citation analysis and to review the clinical impact of the research conducted by the most highly cited researchers. The lifetime journal publication records of 109 psycho-oncology and supportive care researchers in Canada were subject to citation analysis using the Scopus database, based on citations since 1996 of articles deemed relevant to psychosocial oncology and supportive care, excluding self-citations. Three primary types of analysis were performed for each individual: the number of citations for each journal publication, a summative citation count of all published articles, and the Scopus h-index. The top 20 psycho-oncology/supportive care researchers for each of five citation categories are presented: the number of citations for all publications; the number of citations for first-authored publications; the most highly cited first-authored publications; the Scopus h-index for all publications; and the Scopus h-index for first-authored publications. The three most highly cited Canadian psycho-oncology researchers are Dr. Kerry Courneya (University of Alberta), Dr. Lesley Degner, (University of Manitoba), and Dr. Harvey Chochinov (University of Manitoba). Citation analysis is useful for examining the research performance of psycho-oncology and supportive care researchers and identifying leaders among them.

Citation screening, an integral process within systematic reviews that identifies citations relevant to the underlying research question, is a time-consuming and resource-intensive task. During the screening task, analysts manually assign a label to each citation, to designate whether a citation is eligible for inclusion in the review. Recently, several studies have explored the use of active learning in text classification to reduce the human workload involved in the screening task. However, existing approaches require a significant amount of manually labelled citations for the text classification to achieve a robust performance. In this paper, we propose a semi-supervised method that identifies relevant citations as early as possible in the screening process by exploiting the pairwise similarities between labelled and unlabelled citations to improve the classification performance without additional manual labelling effort. Our approach is based on the hypothesis that similar citations share the same label (e.g., if one citation should be included, then other similar citations should be included also). To calculate the similarity between labelled and unlabelled citations we investigate two different feature spaces, namely a bag-of-words and a spectral embedding based on the bag-of-words. The semi-supervised method propagates the classification codes of manually labelled citations to neighbouring unlabelled citations in the feature space. The automatically labelled citations are combined with the manually labelled citations to form an augmented training set. For evaluation purposes, we apply our method to reviews from clinical and public health. The results show that our semi-supervised method with label propagation achieves statistically significant improvements over two state-of-the-art active learning approaches across both clinical and public health reviews.

The purpose of this study is to determine and characterize the scientific and nonscientific factors that influence the rate of article citation in the field of plastic surgery. Cross-sectional study. We reviewed all entries in Annals of Plastic Surgery and Journal of Plastic, Reconstructive, and Aesthetic Surgery from January 1, 2007 to December 31, 2007; and Plastic and Reconstructive Surgery from January 1, 2007 to December 31, 2008. All scientific articles were analyzed and several article characteristics were extracted. The number of citations at 5 years was collected as the outcome variable. A multivariable analysis was performed to determine which variables were associated with higher citations rates. A total of 2456 articles were identified of which only 908 fulfilled the inclusion criteria. Most studies were publications in the fields of reconstructive (26.3%) or pediatric/craniofacial (17.6%) surgery. The median number of citations 5 years from publication was 8. In the multivariable analysis, factors associated with higher citations rates were subspecialty field (p = 0.0003), disclosed conflict of interest (p = 0.04), number of authors (p = 0.04), and journal (p = 0.02). We have found that higher level of evidence (or other study methodology factors) is not associated with higher citation rates. Instead, conflict of interest, subspecialty topic, journal, and number of authors are strong predictors of high citation rates in plastic surgery.

Data reuse and the open data citation advantage.

Science.gov (United States)

Piwowar, Heather A; Vision, Todd J

2013-01-01

Background. Attribution to the original contributor upon reuse of published data is important both as a reward for data creators and to document the provenance of research findings. Previous studies have found that papers with publicly available datasets receive a higher number of citations than similar studies without available data. However, few previous analyses have had the statistical power to control for the many variables known to predict citation rate, which has led to uncertain estimates of the "citation benefit". Furthermore, little is known about patterns in data reuse over time and across datasets. Method and Results. Here, we look at citation rates while controlling for many known citation predictors and investigate the variability of data reuse. In a multivariate regression on 10,555 studies that created gene expression microarray data, we found that studies that made data available in a public repository received 9% (95% confidence interval: 5% to 13%) more citations than similar studies for which the data was not made available. Date of publication, journal impact factor, open access status, number of authors, first and last author publication history, corresponding author country, institution citation history, and study topic were included as covariates. The citation benefit varied with date of dataset deposition: a citation benefit was most clear for papers published in 2004 and 2005, at about 30%. Authors published most papers using their own datasets within two years of their first publication on the dataset, whereas data reuse papers published by third-party investigators continued to accumulate for at least six years. To study patterns of data reuse directly, we compiled 9,724 instances of third party data reuse via mention of GEO or ArrayExpress accession numbers in the full text of papers. The level of third-party data use was high: for 100 datasets deposited in year 0, we estimated that 40 papers in PubMed reused a dataset by year 2, 100 by

Opening the Dissertation: Overcoming Cultural Calcification and Agoraphobia

Directory of Open Access Journals (Sweden)

Denise Troll Covey

2013-11-01

Full Text Available This article places the struggle to open access to the dissertation in the context of the crisis in doctoral education and the transition from print to digital literacy. It explores the underlying cultural calcification and agoraphobia that deter engagement with openness. Solving the problems will require overhauling the curriculum and conventions of doctoral education. Opening access to dissertations is an important first step, but insufficient to end the crisis. Only opening other dimensions of the dissertation – the structure, media, notion of authorship, and methods of assessment – can foster the digital literacy needed to save PhD programs from extinction. If higher education institutions invested heavily in remedying obsolete practices, the remedies would reverberate throughout the academy, accelerate advancement in the disciplines, and revolutionize scholarly publishing. The article ends with a discussion of the significant role librarians could play in facilitating needed changes given appropriate institutional commitment.

Ranking Scientific Publications Based on Their Citation Graph

CERN Document Server

Marian, L; Rajman, M

2009-01-01

CDS Invenio is the web-based integrated digital library system developed at CERN. It is a suite of applications which provides the framework and tools for building and managing an autonomous digital library server. Within this framework, the goal of this project is to implement new ranking methods based on the bibliographic citation graph extracted from the CDS Invenio database. As a first step, we implemented the Citation Count as a baseline ranking method. The major disadvantage of this method is that all citations are treated equally, disregarding their importance and their publication date. To overcome this drawback, we consider two different approaches: a link-based approach which extends the PageRank model to the bibliographic citation graph and a time-dependent approach which takes into account time in the citation counts. In addition, we also combined these two approaches in a hybrid model based on a time-dependent PageRank. In the present document, we describe the conceptual background behind our new...

Citation analysis of mental health nursing journals: how should we rank thee?

Science.gov (United States)

Hunt, Glenn E; Happell, Brenda; Chan, Sally W-C; Cleary, Michelle

2012-12-01

The journal impact factor (JIF), and how best to rate the performance of a journal and the articles they contain, are areas of great debate. The aim of this paper was to assess various ranking methods of journal quality for mental health nursing journals, and to list the top 10 articles that have received the most number of citations to date. Seven mental health nursing journals were chosen for the analysis of citations they received in 2010, as well as their current impact factors from two sources, and other data for ranking purposes. There was very little difference in the top four mental health nursing journals and their overall rankings when combining various bibliometric indicators. That said, the International Journal of Mental Health Nursing is currently the highest ranked mental health nursing journal based on JIF, but publishes fewer articles per year compared to other journals. Overall, very few articles received 50 or more citations. This study shows that researchers need to consider more than one ranking method when deciding where to send or publish their research. © 2012 The Authors.

2009-01-01

In the scientific research community, plagiarism and covert multiple publications of the same data are considered unacceptable because they undermine the public confidence in the scientific integrity. Yet, little has been done to help authors and editors to identify highly similar citations, which sometimes may represent cases of unethical duplication. For this reason, we have made available Déjà vu, a publicly available database of highly similar Medline citations identified by the text similarity search engine eTBLAST. Following manual verification, highly similar citation pairs are classified into various categories ranging from duplicates with different authors to sanctioned duplicates. Déjà vu records also contain user-provided commentary and supporting information to substantiate each document's categorization. Déjà vu and eTBLAST are available to authors, editors, reviewers, ethicists and sociologists to study, intercept, annotate and deter questionable publication practices. These tools are part of a sustained effort to enhance the quality of Medline as 'the' biomedical corpus. The Déjà vu database is freely accessible at http://spore.swmed.edu/dejavu. The tool eTBLAST is also freely available at http://etblast.org.

Do usage and scientific collaboration associate with citation impact

Chi, P.S.; Glänzel, W.

2016-07-01

In this study usage counts and times cited from Web of Science Core Collection (WoS) were collected for each article published in 2013 with Belgian, Israeli and Iranian addresses. We investigate the relations among three indicators related to citation impact, usage counts coauthorship, respectively. In addition, we apply the method of Characteristic Scores and Scal (CSS) to analyse the distributions of citations and usage counts. The results show that citations and usage counts in WoS correlate to each other significantly, especially in the social sciences. However, the increase of the number of co-authors does not increase usage counts or citations significantly. Furthermore, the stability of CSS-class distributions proves the availability of CSS in characterising both usage and citation distributions. (Author)

Formarier, M; Tchassou, P

1998-03-01

The writing of the study end dissertation, in the degree course of the student nurses poses pedagogical as well as methodological problems. The goal of the study end dissertation, if this latter takes the form of a research, is not a production of knowledge, but a methodological and conceptual learning. The critical analysis of 142 study end dissertations highlights a level heterogeneousness, a total lack of research problematics and unsuitable methodologies. The study end dissertation does not take the form of a research but of a reflection work, chosen by the student.

Self-citations at the meso and individual levels: effects of different calculation methods.

Science.gov (United States)

Costas, Rodrigo; van Leeuwen, Thed N; Bordons, María

2010-03-01

This paper focuses on the study of self-citations at the meso and micro (individual) levels, on the basis of an analysis of the production (1994-2004) of individual researchers working at the Spanish CSIC in the areas of Biology and Biomedicine and Material Sciences. Two different types of self-citations are described: author self-citations (citations received from the author him/herself) and co-author self-citations (citations received from the researchers' co-authors but without his/her participation). Self-citations do not play a decisive role in the high citation scores of documents either at the individual or at the meso level, which are mainly due to external citations. At micro-level, the percentage of self-citations does not change by professional rank or age, but differences in the relative weight of author and co-author self-citations have been found. The percentage of co-author self-citations tends to decrease with age and professional rank while the percentage of author self-citations shows the opposite trend. Suppressing author self-citations from citation counts to prevent overblown self-citation practices may result in a higher reduction of citation numbers of old scientists and, particularly, of those in the highest categories. Author and co-author self-citations provide valuable information on the scientific communication process, but external citations are the most relevant for evaluative purposes. As a final recommendation, studies considering self-citations at the individual level should make clear whether author or total self-citations are used as these can affect researchers differently.

Self-citation of Medical and Non-medical Universities in Northern Iran.

Science.gov (United States)

Jahani, Mohammad Ali; Yaminfirooz, Mousa

2016-12-01

Self-citation is one of the main challenges in the evaluation of researchers' scientific output. This study aimed at comparing the institutional self-citation among the universities located in Northern Iran. This study was conducted as a scientometric study. Research population included all scientific productions of 16 Northern Iran Universities with at least 100 indexed documents indexed in the Web of Science (WoS) by 2 June 2015. The citation analysis section of WoS was used for data collection. SPSS was applied for data analysis. Study hypotheses were tested with two independent sample t-test and paired sample t-test. Producing 16,399 papers, northern Iran universities had 5.33% of contribution in Iran's scientific production. They received 84,058 citations with 17% and 12% of self-citations belonged to the non-medical and medical universities, respectively. Testing hypotheses revealed that increase in received citations significantly increases the rate of self-citation and increase in scientific production does not necessarily increase the rate of self-citation. The rate of self-citation in the studied universities was not relatively high. However, investigating into the factors affecting the rate of and motives for self-citation needs further research.

Data reuse and the open data citation advantage

Directory of Open Access Journals (Sweden)

Heather A. Piwowar

2013-10-01

Full Text Available Background. Attribution to the original contributor upon reuse of published data is important both as a reward for data creators and to document the provenance of research findings. Previous studies have found that papers with publicly available datasets receive a higher number of citations than similar studies without available data. However, few previous analyses have had the statistical power to control for the many variables known to predict citation rate, which has led to uncertain estimates of the “citation benefit”. Furthermore, little is known about patterns in data reuse over time and across datasets. Method and Results. Here, we look at citation rates while controlling for many known citation predictors and investigate the variability of data reuse. In a multivariate regression on 10,555 studies that created gene expression microarray data, we found that studies that made data available in a public repository received 9% (95% confidence interval: 5% to 13% more citations than similar studies for which the data was not made available. Date of publication, journal impact factor, open access status, number of authors, first and last author publication history, corresponding author country, institution citation history, and study topic were included as covariates. The citation benefit varied with date of dataset deposition: a citation benefit was most clear for papers published in 2004 and 2005, at about 30%. Authors published most papers using their own datasets within two years of their first publication on the dataset, whereas data reuse papers published by third-party investigators continued to accumulate for at least six years. To study patterns of data reuse directly, we compiled 9,724 instances of third party data reuse via mention of GEO or ArrayExpress accession numbers in the full text of papers. The level of third-party data use was high: for 100 datasets deposited in year 0, we estimated that 40 papers in PubMed reused a

Growing complex network of citations of scientific papers: Modeling and measurements.

Science.gov (United States)

Golosovsky, Michael; Solomon, Sorin

2017-01-01

We consider the network of citations of scientific papers and use a combination of the theoretical and experimental tools to uncover microscopic details of this network growth. Namely, we develop a stochastic model of citation dynamics based on the copying-redirection-triadic closure mechanism. In a complementary and coherent way, the model accounts both for statistics of references of scientific papers and for their citation dynamics. Originating in empirical measurements, the model is cast in such a way that it can be verified quantitatively in every aspect. Such validation is performed by measuring citation dynamics of physics papers. The measurements revealed nonlinear citation dynamics, the nonlinearity being intricately related to network topology. The nonlinearity has far-reaching consequences including nonstationary citation distributions, diverging citation trajectories of similar papers, runaways or "immortal papers" with infinite citation lifetime, etc. Thus nonlinearity in complex network growth is our most important finding. In a more specific context, our results can be a basis for quantitative probabilistic prediction of citation dynamics of individual papers and of the journal impact factor.

Journal rankings by citation analysis in health sciences librarianship.

Fang, M L

1989-01-01

The purpose of this study was to identify objectively a hierarchical ranking of journals for health sciences librarians with faculty status. Such a guideline can indicate a journal's value for promotion and tenure consideration. Lists of recent research articles (1982-1986) in health sciences librarianship, and articles written by health sciences librarians, were compiled by searching Social SCISEARCH and MEDLINE. The journals publishing those articles are presented. Results show BMLA as the most prominent journal in the field. Therefore, citations from articles in BMLA from 1982 to 1986 were chosen as a sample for citation analysis. Citation analysis was employed to identify the most frequently cited journals. Some characteristics of the citations in BMLA are also discussed. The ranking of journals based on citation frequency, as a result, was identified. PMID:2655785

Nemtsov, A V; Kuznetsova-Moreva, E A

To evaluate the zero-citation sizes. Based on the data of the Russian Science Citation Index the publication activity of four leading institutes in the field of Psychiatry and Addiction is analyzed. The same indices in the field of Neurology were used as a control. Number and percentage of publications with ≥1 citations and zero-citation were analyzed. It has been shown that in psychiatric science zero citation rate is quite high (from 32.8% to 47.2%, an average of 42.9%). It is higher compared to the control. Zero-citation indicator is essential to evaluate the effectiveness of scientific institutions.

- What is the impact of patent citations on patent renewal behaviour? Patent citations are commonly used as an indicator of technology spillovers. For cited patents therefore, patent citations have a potentially ambiguous impact. On the one hand, patent citations may indicate a scientific breakthrough, a high value of the cited patent and therefore a long survival period. On the other hand, patent citations may indicate competing innovations that render the cited patent obsolete. By discri...

Perbal, Annick

2017-09-01

The recent publication of a commentary article by Dadkhah et al. (J Cell Commun Signal 11:181-185, 2017) which addressed issues raised by the citation of questionable scientific papers in current databases and the recent retraction of manuscripts dealing with the biological properties of the CCN1 protein by Lin et al. (J Biol Chem 291(53):27433, 2016) prompted us to examine how this situation reflects an evolution of the original citation system, endangering scientific communication. We argue that the increasing number of publication retractions that have been witnessed over several years is a direct consequence of the bias created by the inconsistency of citation metrics.

Misuse of anecdotes in primatology: lessons from citation analysis.

Science.gov (United States)

Sarringhaus, Lauren A; McGrew, William C; Marchant, Linda F

2005-03-01

This study analyzes the accuracy of anecdotes cited in behavioral primatology publications. Anecdotes (n=1 cases) recounting tool use were sought in the four main primatological journals. Citations of anecdotes in the scientific literature that met three criteria were systematically coded for recognition and accuracy. The results showed that 60% of the time, authors who cited anecdotes did not explicitly acknowledge them as such. To a lesser extent, the citations exaggerated the frequency of anecdotal events or misrepresented their status. For tool use specifically, the actor was misreported more often than the tool or its target. Multiple citations were incorrect more often than single citations. Overall, it seems that citation of anecdotes is problematic and may have far-reaching implications in terms of misleading overgeneralizations. Primatologists should take care in citing singular or rare events. Copyright (c) 2005 Wiley-Liss, Inc.

Science.gov (United States)

Bador, Pascal; Lafouge, Thierry

2012-01-01

In order to characterize scientific collaboration the best way is to study co-signature of articles. Two indicators are interesting: number of authors and international character. The objective is to study correlation between these two indicators and citation number. We selected two pharmacy and medicine journals in order to compare practices. We used a sample of about 800 articles published in 2002-2005 for which we collected citations up to 2010. We transformed numeric variables, authors number and citation number, into qualitative variables. "Authors" and "Citations" variables are not independent. Less cited articles are often published by one author or a very small team while international character of articles generally increases citation number. This micro-analysis also allowed us to better understand publication practices. © 2012 Société Française de Pharmacologie et de Thérapeutique.

Citation Analysis of the Korean Journal of Urology From Web of Science, Scopus, Korean Medical Citation Index, KoreaMed Synapse, and Google Scholar.

Science.gov (United States)

Huh, Sun

2013-04-01

The Korean Journal of Urology began to be published exclusively in English in 2010 and is indexed in PubMed Central/PubMed. This study analyzed a variety of citation indicators of the Korean Journal of Urology before and after 2010 to clarify the present position of the journal among the urology category journals. The impact factor, SCImago Journal Rank (SJR), impact index, Z-impact factor (ZIF, impact factor excluding self-citation), and Hirsch Index (H-index) were referenced or calculated from Web of Science, Scopus, SCImago Journal & Country Ranking, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, and Google Scholar. Both the impact factor and the total citations rose rapidly beginning in 2011. The 2012 impact factor corresponded to the upper 84.9% in the nephrology-urology category, whereas the 2011 SJR was in the upper 58.5%. The ZIF in KoMCI was one fifth of the impact factor because there are only two other urology journals in KoMCI. Up to 2009, more than half of the citations in the Web of Science were from Korean researchers, but from 2010 to 2012, more than 85% of the citations were from international researchers. The H-indexes from Web of Science, Scopus, KoMCI, KoreaMed Synapse, and Google Scholar were 8, 10, 12, 9, and 18, respectively. The strategy of the language change in 2010 was successful from the perspective of citation indicators. The values of the citation indicators will continue to increase rapidly and consistently as the research achievement of authors of the Korean Journal of Urology increases.

Citation analysis provides insights into the history and developmental trajectory of scientific fields. Our objective was to perform an analysis of citation classics in the journals of pediatric specialty and to examine their characteristics. 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. 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). The top-100 cited articles in pediatrics identify the impactful authors, journals, institutes, and countries. Observational study design was predominant-implying that inclusion among citation classics is not related to soundness of study design.

A comparison of citations across multidisciplinary psychology journals: a case study of two independent journals.

Science.gov (United States)

Schumm, Walter R

2010-02-01

Citation rates and impact factors are often used in an attempt to evaluate the apparent prestige of scholarly journals and the quality of research published by individual scholars. However, the apparent prestige of "top tier" journals may reflect aggressive marketing and advertising efforts as much as scholarship. Some journals have retained their independence from professional organizations and the funding, marketing, and advocacy policies that may be associated with such organizations. While lacking as much visibility as organizational journals and sometimes considered "lower tier," independent journals may be able to provide comparable scientific quality as measured by citation rates. To test this, the citation rates of 169 articles published by a frequently cited scholar were compared across first- and second-tier journals, including many sponsored and marketed by large professional organizations, and to rates for two independent journals combined, Psychological Reports and Perceptual and Motor Skills. Citation rates were higher for first-tier journals but for most comparisons, especially those that controlled for heterogeneity of variance, results did not differ in statistically significant ways among the three tiers of journals, though some nonsignificant trends (p journals appear to be a relatively weak indicator of scientific merit; journals at any tier contain articles that are useful and of good quality.

[Chartered specialist training in gerontology and geriatrics. Dissertation Council no. 601.001.01 working practice].

Kozina, L S

2014-01-01

The article highlights basic facts about the foundation and activity of the Gerontology and Geriatrics Dissertation Council of St. Petersburg Institute of Bioregulation and Gerontology, which took invaluable part in chartered specialist training in this field of science that has actively developed in Russia in recent decades. Over the period from June, 2001 to December, 2013, a total of 41 doctoral dissertations were defended, of which 32 dissertations were on Medicine and 9 on Biological Sciences. Likewise, over the same period, a total of 186 candidate's dissertations were defended, of which 152 dissertations were on Medicine and 34 on Biological Sciences, the defenders coming from various regions of Russia and other countries. The defence-representative trend data acquired over the period of the Dissertation Council activities shows that the number of defended doctoral dissertations was relatively small within the period from 2002 to 2008, but it increased significantly in the years 2009 to 2013. The number of defended candidate's dissertations increased significantly over the same period, too. Among many others considered by the Dissertation Council, there were dissertations dedicated to basic research in the field of gerontology and geriatrics. The priority topics of a large number of dissertations performed in St. Petersburg and other Russian towns are age pathology mechanisms, geroprotective effects of regulatory peptides and effectiveness of their use in clinic.

Scientific citations favor positive results: a systematic review and meta-analysis.

Citation bias concerns the selective citation of scientific articles based on their results. We brought together all available evidence on citation bias across scientific disciplines and quantified its impact. An extensive search strategy was applied to the Web of Science Core Collection and Medline, yielding 52 studies in total. We classified these studies on scientific discipline, selection method, and other variables. We also performed random-effects meta-analyses to pool the effect of positive vs. negative results on subsequent citations. Finally, we checked for other determinants of citation as reported in the citation bias literature. Evidence for the occurrence of citation bias was most prominent in the biomedical sciences and least in the natural sciences. Articles with statistically significant results were cited 1.6 (95% confidence interval [CI] 1.3-1.8) times more often than articles with nonsignificant results. Articles in which the authors explicitly conclude to have found support for their hypothesis were cited 2.7 (CI 2.0-3.7) times as often. Article results and journal impact factor were associated with citation more often than any other reported determinant. Similar to what we already know on publication bias, also citation bias can lead to an overrepresentation of positive results and unfounded beliefs. Copyright © 2017 Elsevier Inc.

The relationship between traditional metrics of research impact (e.g., number of citations) and alternative metrics (altmetrics) such as Twitter activity are of great interest, but remain imprecisely quantified. We used generalized linear mixed modeling to estimate the relative effects of Twitter activity, journal impact factor, and time since publication on Web of Science citation rates of 1,599 primary research articles from 20 ecology journals published from 2012-2014. We found a strong positive relationship between Twitter activity (i.e., the number of unique tweets about an article) and number of citations. Twitter activity was a more important predictor of citation rates than 5-year journal impact factor. Moreover, Twitter activity was not driven by journal impact factor; the 'highest-impact' journals were not necessarily the most discussed online. The effect of Twitter activity was only about a fifth as strong as time since publication; accounting for this confounding factor was critical for estimating the true effects of Twitter use. Articles in impactful journals can become heavily cited, but articles in journals with lower impact factors can generate considerable Twitter activity and also become heavily cited. Authors may benefit from establishing a strong social media presence, but should not expect research to become highly cited solely through social media promotion. Our research demonstrates that altmetrics and traditional metrics can be closely related, but not identical. We suggest that both altmetrics and traditional citation rates can be useful metrics of research impact.

Bibliometrics of systematic reviews: analysis of citation rates and journal impact factors

Science.gov (United States)

2013-01-01

Background Systematic reviews are important for informing clinical practice and health policy. The aim of this study was to examine the bibliometrics of systematic reviews and to determine the amount of variance in citations predicted by the journal impact factor (JIF) alone and combined with several other characteristics. Methods We conducted a bibliometric analysis of 1,261 systematic reviews published in 2008 and the citations to them in the Scopus database from 2008 to June 2012. Potential predictors of the citation impact of the reviews were examined using descriptive, univariate and multiple regression analysis. Results The mean number of citations per review over four years was 26.5 (SD ±29.9) or 6.6 citations per review per year. The mean JIF of the journals in which the reviews were published was 4.3 (SD ±4.2). We found that 17% of the reviews accounted for 50% of the total citations and 1.6% of the reviews were not cited. The number of authors was correlated with the number of citations (r = 0.215, P reviews published in the top quartile of JIFs (≥ 5.16) received citations in the bottom quartile (eight or fewer), whereas 9% of reviews published in the lowest JIF quartile (≤ 2.06) received citations in the top quartile (34 or more). Six percent of reviews in journals with no JIF were also in the first quartile of citations. Conclusions The JIF predicted over half of the variation in citations to the systematic reviews. However, the distribution of citations was markedly skewed. Some reviews in journals with low JIFs were well-cited and others in higher JIF journals received relatively few citations; hence the JIF did not accurately represent the number of citations to individual systematic reviews.

Herterich, Patricia

2016-01-01

A paradigm change in scholarly communication is underway. Supporting Open Science, an effort to make scientific research data accessible to all interested parties by openly publishing research and encouraging others to do the same thereby making it easier to communicate scientific knowledge, is a part of the change that has become increasingly important for (digital) libraries. Digital libraries are able to play a significant role in enabling Open Science by facilitating data sharing, discovery and re-use. Because data citation is often mentioned as one incentive for data sharing, enabling data citation is a crucial feature of research data services. In this article we present a case study of data citation services for the High-Energy Physics (HEP) community using digital library technology. Our example shows how the concept of data citation is implemented for the complete research workflow, covering data production, publishing, citation and tracking of data reuse. We also describe challenges faced and distil...

2009-07-01

Full Text Available Dissertations and theses that are generated in course of research at PhD and Masters levels are considered to be important scientific documents in every country. Data description and analysis of such documents collected together, could automatically - especially when compared with data from other resources - provide new information that is very valuable. Nevertheless, no comprehensive, integrated pattern exists for such description and analysis. The present paper offers the findings of a research conducted for devising an information analysis pattern for dissertations and theses. It also puts forward information categories derived from such documents that could be described and analyzed.

Turkish Publications in Science Citation Index and Citation Index-Expanded Indexed Journals in the Field of Anaesthesiology: A Bibliographic Analysis.

Özbilgin, Şule; Hancı, Volkan

2017-02-01

Our study aimed to assess Turkish publications in Science Citation Index (SCI) and Science Citation Index Expanded (SCI-E) indexed journals in the field of 'anaesthesiology'. Journals related to 'anaesthesiology' in the Science Citation Index-Expanded database of 'Thomson Reuter Web of Science' were searched. The search engine of Institute for Scientific Information (ISI) Web of Science (WoS) was used in the advanced mode by typing 'IS=ISSN number' to identify publications in the journal. By typing 'IS=ISSN number AND CU=Turkey', Turkish papers on anaesthesiology were found. If Turkish and non-Turkish authors had collaborated, the article was included in the search when the corresponding author had provided a Turkey-based address. The catalogue information and statistics were used to determine Turkish publications as the percentage of total publications and the annual mean number of Turkish publications. In WoS, 'SU=anesthesiology' was used to determine the number, country, year and topic distributions of publications from 1975 to date and within the last 10 years. The citation numbers and h-indices were determined based on the country for publications within the last 10 years. From 1975 to the early 2000s Turkey was 20 th in the list of countries with highest number of publications on anaesthesiology, however in the last 10 years Turkey moved up to 18 th place. Its mean citation number has been 4.64, and it remains the 2 nd lowest country pertaining to citations among the 22 countries with the most number of publications. According to the percentage of publications in the field of anaesthesiology, the journals with highest rate of Turkish publications were Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. In the field of anaesthesiology, the highest number of articles from Turkey was published in Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia.

Personal Ties in the Writing of a Doctoral Dissertation

Directory of Open Access Journals (Sweden)

Laura Colombo

2014-07-01

Full Text Available The problem of low graduation rates at the graduate level has been linked to the challenges of dissertation work. Given that this is a process of “disciplinary enculturation”, where graduate students acquire the ways of being and doing of each discipline, the social relations of doctoral candidates should be analyzed. Several studies have explored the support provided by social ties within academia but have, nevertheless, ignored other spheres. This qualitative study, based on in-depth interviews, explores the personal-sphere social relations in the dissertation writing process from the point of view of doctoral candidates and recent graduates in the fields of Education and Linguistics. Results indicate that the emotional, financial, economic, and academic support offered by these social ties is a necessary, although not in itself, sufficient condition. Some strategies for increasing institutional support to facilitate the process of writing a dissertation are offered.

2016-07-01

Purpose To determine if adherence to the Standards for Reporting of Diagnostic Accuracy (STARD) is associated with postpublication citation rates. Materials and Methods A comprehensive search of PubMed, EMBASE, and Cochrane Library databases was performed to identify published articles that have evaluated adherence of diagnostic accuracy studies to the STARD statement. These were included if the number of STARD items reported ("STARD result") could be obtained for each evaluated study. The date of publication, journal impact factor, and citation rate (citations per day) were extracted for the diagnostic accuracy studies. Univariate correlations were performed to identify any association between STARD result, impact factor, and citation rate. Multivariate regression analysis was performed to explore the effect of impact factor on postpublication citation rates. Results The authors were able to obtain the STARD results for 1002 "original" diagnostic accuracy studies from eight different "STARD evaluation" articles. The median impact factor was 3.97 (interquartile range [IQR]: 2.32-6.21), the median STARD result was 15 of 25 items (IQR: 12-18), and the median citation rate was 0.007 citations per day (IQR: 0.0032-0.017). The authors identified a weak positive correlation between STARD result and citation rate (r = 0.096; 95% confidence interval [CI]: 0.034, 0.157), a moderate positive correlation between impact factor and citation rate (r = 0.58; 95% CI: 0.535, 0.617), and a weak positive correlation between impact factor and STARD result (r = 0.13; 95% CI: 0.064, 0.186). Multivariate analysis accounting for journal clustering effects revealed that, when impact factor is partialed out, the positive correlation between citation rate and STARD result does not persist (r = 0.029; 95% CI: -0.033, 0.091). Conclusion There is a positive correlation between completeness of reporting, as evaluated with STARD, and citation rate as well as impact factor. When adjusted for

Citation metrics of excellence in sports biomechanics research.

Knudson, Duane

2017-11-13

This study extended research on key citation metrics of winners of two career scholar awards in sports biomechanics. Google Scholar (GS) was searched using Harzing's Publish or Perish software for the 13 most recent winners of the ISBS Geoffrey Dyson Award and the ASB Jim Hay Memorial Award. Returned records were corrected for author, and publications excluded for all but peer-reviewed journal articles, proceedings articles, chapters and books in English. These recent award winners had published about 150 publications that had been cited typically 4,082 and 6,648 times over a 26- and 28-year period before receiving these career awards for sports biomechanics research. Estimated median citations at time of their awards were 2,927 and 4,907 for the Dyson and Hay awards, respectively. Award winners had mean Hirsh indexes of 32-45 and mean h i of 19-28. Their mean g indexes (59-84) and their numerous citation classics (C > 100) indicated that they had many influential publications. The citation metrics of these scholars were outstanding and consistent with recent studies of top scholars in biomechanics and kinesiology/exercise science. Careful searching, cleaning and interpretation of several scholar-level citation metrics may provide useful confirmatory evidence for evaluations of awards committees.

Full Text Available ABSTRACT. The indigenous education in Brazil has its founding milestone in the first catechetical actions of the Jesuits in the second half of the sixteenth century. In this long trajectory up to the present day the education of the indigenous peoples that inhabit the Brazilian territory has been the subject of controversies and discussions at the governmental and academic levels, which has generated numerous studies. This research had as objective to elaborate a bibliometric panorama of the scientific production on indigenous education present in theses and dissertations of the Brazilian Digital Library of Thesis and Dissertations (BDTD / IBICT through bibliometric methodology. The corpus analyzed was composed of 173 postgraduate studies defended in the country between 1996 and 2016. The results indicate that the Southeast and South regions, respectively, concentrate the largest number of papers and that the Education area is the majority in the Scientific production of the thesis and dissertations recovered.

Vectorization of three-dimensional neutron diffusion code CITATION

International Nuclear Information System (INIS)

Harada, Hiroo; Ishiguro, Misako

1985-01-01

Three-dimensional multi-group neutron diffusion code CITATION has been widely used for reactor criticality calculations. The code is expected to be run at a high speed by using recent vector supercomputers, when it is appropriately vectorized. In this paper, vectorization methods and their effects are described for the CITATION code. Especially, calculation algorithms suited for vectorization of the inner-outer iterative calculations which spend most of the computing time are discussed. The SLOR method, which is used in the original CITATION code, and the SOR method, which is adopted in the revised code, are vectorized by odd-even mesh ordering. The vectorized CITATION code is executed on the FACOM VP-100 and VP-200 computers, and is found to run over six times faster than the original code for a practical-scale problem. The initial value of the relaxation factor and the number of inner-iterations given as input data are also investigated since the computing time depends on these values. (author)

A Citation Tracking System to Facilitate Sponsoring Institution Oversight of ACGME-Accredited Programs.

Long, Timothy R; Poe, John D; Zimmerman, Richard S; Rose, Steven H

2012-12-01

The Accreditation Council for Graduate Medical Education (ACGME) requires the graduate medical education committee and the designated institutional official to ensure that citations for noncompliance with the accreditation standards and institutional trends in citations are reviewed and corrected. To describe a citation tracking system (CTS) that uses Microsoft Office Access to efficiently catalogue, monitor, and document resolution of citations. The CTS was implemented in a sponsoring institution with oversight of 133 ACGME-accredited programs. The designated institutional official and the graduate medical education committee review all program letters of notification and enter citations into the CTS. A program-correction plan is required for each citation and is entered into the database. Open citations and action plans are reviewed by the graduate medical education committee and the designated institutional official on a quarterly basis, with decisions ranging from "closing" the citation to approving the action plan in process to requiring a new or modified action plan. Citation categories and subcategories are accessed on the ACGME website and entered into the CTS to identify trends. All 236 citations received since the 2006 Mayo School of Graduate Medical Education institutional site visit were entered into the CTS. On November 22, 2011, 26 of 236 citations (11%) were in active status with ongoing action plans, and 210 (89%) citations had been resolved and were closed. The CTS uses commercially available software to ensure citations are monitored and addressed and to simplify analysis of citation trends. The approach requires minimal staff time for data input and updates and can be performed without institutional information technology assistance.

Application of progressive nucleation mechanism for the citation behavior of individual papers of different authors.

Science.gov (United States)

Sangwal, Keshra

2012-09-01

The basic concepts and equations of the progressive nucleation mechanism (PNM) are presented first for the growth and decay of items. The mechanism is then applied to describe the cumulative citations L and citations ΔL per year of the individual most-cited papers i of four selected Polish professors as a function of citation duration t. It was found that the PNM satisfactorily describes the time dependence of cumulative citations L of the papers published by different authors with sufficiently high citations ΔL, as represented by the highest yearly citations ΔL(max) during the entire citation period t (normal citation behavior). The citation period for these papers is less than 15 years and it is even 6-8 years in several cases. However, for papers with citation periods exceeding about 15 years, the growth behavior of citations does not follow the PNM in the entire citation period (anomalous citation behavior), and there are regions of citations in which the citation data may be described by the PNM. Normal and anomalous citation behaviors are attributed, respectively, to the occurrence and nonoccurrence of stationary nucleation of citations for the papers. The PNM also explains the growth and decay of citations ΔL per year of papers exhibiting normal citation behavior.

AIM: To define the 100 citation classic papers of interventional radiology. METHODS: Using the database of Journal Citation Reports the 40 highest impact factor radiology journals were chosen. From these journals the 100 most cited interventional radiology papers were chosen and analysed. RESULTS: The top paper received 2497 citations and the 100th paper 200 citations. The average number of citations was 320. Dates of publication ranged from 1953 - 2005. Most papers originated in the United States (n = 67) followed by Italy (n = 20) and France (n = 10). Harvard University (n = 18) and Osped Civile (n = 11) were the most prolific institutions. Ten journals produced all of the top 100 papers with “Radiology” and “AJR” making up the majority. SN Goldberg and T Livraghi were the most prolific authors. Nearly two thirds of the papers (n = 61) were published after 1990. CONCLUSION: This analysis identifies many of the landmark interventional radiology papers and provides a fascinating insight into the changing discourse within the field. It also identifies topics, authors and institutions which have impacted greatly on the specialty. PMID:25918585

Web-based Citation Management Systems: Which One Is Best?

Directory of Open Access Journals (Sweden)

Michael Steeleworthy

2013-04-01

Full Text Available Librarians and researchers have long used citation management systems as research tools to help scholars organize their work, improve workflows, and ultimately save time. For many years, RefWorks has been the dominant citation management tool in many parts of Canada: the maturity of the product and its integration with many scholarly databases reassures users that it works well with these resources. However, a number of competitors now offer citation management systems that are as strong as RefWorks but offer different features to the user, therefore warranting a comparison with this leading tool. This paper reviews RefWorks, Zotero, WizFolio, and Mendeley, which are all popular citation management systems that either have a long history of use or are now gaining traction in Canadian academic circles. To compare these tools, we examined their import capabilities as well as their organizing, searching, annotating, and sharing functions. This review will interest both librarians and researchers who are considering alternative citation management systems at either the personal or organizational level.

What Effect Does Self-Citation Have on Bibliometric Measures in Academic Plastic Surgery?

Swanson, Edward W; Miller, Devin T; Susarla, Srinivas M; Lopez, Joseph; Lough, Denver M; May, James W; Redett, Richard J

Research productivity plays a significant role in academic promotions. Currently, various bibliometric measures utilizing citation counts are used to judge an author's work. With increasing numbers of journals, numbers of open access publications, ease of online submission, and expedited indexing of accepted manuscripts, it is plausible that an author could influence his/her own bibliometric measures through self-citation. The purpose of this study was to determine the impact of self-citation in academic plastic surgery. A cohort of full-time academic plastic surgeons was identified from 9 U.S. plastic surgery training programs. For all included faculty, academic rank was retrieved from department/division websites, and bibliometric measures were assessed using a subscription bibliographic citation database (Scopus, Reed Elsevier, London, UK). Bibliometric measures included the Hirsch index (h-index, the number of publications h which are cited ≥ h times), total number of publications, and total number of citations. The h-index and total number of citations were collected with and without self-citations. Percent changes in the h-index and total citations were calculated after removal of self-citations and compared across academic ranks and levels of research productivity (total publications, h-index, and total citations). The study cohort consisted of 169 full-time academic plastic surgeons. The h-index and total citations experienced decreases of 2.8 ± 5.0% (P citation. More than half of the cohort (n = 113, 67%) did not experience a change in the h-index after removal of self-citations. These decreases did not vary across academic rank. Surgeons who self-cited at rates greater than 5% were 9.8 times more likely (95% confidence interval, 4.5-21.9; P citation (after adjusting for academic rank). There were weak correlations between percent decreases in the h-index and total citations and various biblimoteric measures (total publications, h-index, total citations

Database citation in supplementary data linked to Europe PubMed Central full text biomedical articles.

2015-01-01

In this study, we present an analysis of data citation practices in full text research articles and their corresponding supplementary data files, made available in the Open Access set of articles from Europe PubMed Central. Our aim is to investigate whether supplementary data files should be considered as a source of information for integrating the literature with biomolecular databases. Using text-mining methods to identify and extract a variety of core biological database accession numbers, we found that the supplemental data files contain many more database citations than the body of the article, and that those citations often take the form of a relatively small number of articles citing large collections of accession numbers in text-based files. Moreover, citation of value-added databases derived from submission databases (such as Pfam, UniProt or Ensembl) is common, demonstrating the reuse of these resources as datasets in themselves. All the database accession numbers extracted from the supplementary data are publicly accessible from http://dx.doi.org/10.5281/zenodo.11771. Our study suggests that supplementary data should be considered when linking articles with data, in curation pipelines, and in information retrieval tasks in order to make full use of the entire research article. These observations highlight the need to improve the management of supplemental data in general, in order to make this information more discoverable and useful.

The e-index, complementing the h-index for excess citations.

Directory of Open Access Journals (Sweden)

Chun-Ting Zhang

Full Text Available BACKGROUND: The h-index has already been used by major citation databases to evaluate the academic performance of individual scientists. Although effective and simple, the h-index suffers from some drawbacks that limit its use in accurately and fairly comparing the scientific output of different researchers. These drawbacks include information loss and low resolution: the former refers to the fact that in addition to h(2 citations for papers in the h-core, excess citations are completely ignored, whereas the latter means that it is common for a group of researchers to have an identical h-index. METHODOLOGY/PRINCIPAL FINDINGS: To solve these problems, I here propose the e-index, where e(2 represents the ignored excess citations, in addition to the h(2 citations for h-core papers. Citation information can be completely depicted by using the h-index together with the e-index, which are independent of each other. Some other h-type indices, such as a and R, are h-dependent, have information redundancy with h, and therefore, when used together with h, mask the real differences in excess citations of different researchers. CONCLUSIONS/SIGNIFICANCE: Although simple, the e-index is a necessary h-index complement, especially for evaluating highly cited scientists or for precisely comparing the scientific output of a group of scientists having an identical h-index.

Data Citation in Astronomy

Many observatories maintain bibliographies to document their impact and justify their continued funding[1], an effort that requires humans to discover and curate links between the scientific papers and the data that was used as evidence. The "Best Practices for Creating a Telescope Bibliography", endorsed by IAU C5 WG Libraries, recommends full text searching and human examination of each paper.[2] These efforts do not scale well.It is unlikely that articles published in journals from other disciples would be found. This is particularly a problem for solar physics, as solar data has applicability in astrophysics, space weather, and even the earth sciences.As our scientists are not on the editorial boards of the journals from other disciplines, we can't ensure proper attribution to allow these relationships to be discovered via full text searching.To better deal with tracking cross-discipline data usage, a number of groups have come up with guidelines and principles for data citation. In 2012, the National Academy's Board on Research Data and Information released the report "For Attribution-Developing Data Attribution and Citation Practices and Standards" [3] and it was followed last year by the CODATA-ICSTI report "Out of Cite, Out of Mind".[4]Participants from a number of groups synthesized a single set of principles for data citation that could be endorsed by all groups involved in research.[5] Implementing these principles can help to improve the scientific ecosystem by giving proper attribution to all contributors to data, improving transparency and reproducability, and making data more easily reusable to both astronomers and other researchers.We will present the Joint Declaration of Data Citation Principles, discuss the implications of them for astronomical data, and recommend steps towards implementation.References:[1] Accomazzi, et.al, 2012. http://adsabs.harvard.edu/abs/2012SPIE.8448E..0KA[2] Bishop, Grothkopf & Lagerstrom, 2012. http://iau-commission5

A method for the automated, reliable retrieval of publication-citation records.

Directory of Open Access Journals (Sweden)

Derek Ruths

Full Text Available BACKGROUND: Publication records and citation indices often are used to evaluate academic performance. For this reason, obtaining or computing them accurately is important. This can be difficult, largely due to a lack of complete knowledge of an individual's publication list and/or lack of time available to manually obtain or construct the publication-citation record. While online publication search engines have somewhat addressed these problems, using raw search results can yield inaccurate estimates of publication-citation records and citation indices. METHODOLOGY: In this paper, we present a new, automated method that produces estimates of an individual's publication-citation record from an individual's name and a set of domain-specific vocabulary that may occur in the individual's publication titles. Because this vocabulary can be harvested directly from a research web page or online (partial publication list, our method delivers an easy way to obtain estimates of a publication-citation record and the relevant citation indices. Our method works by applying a series of stringent name and content filters to the raw publication search results returned by an online publication search engine. In this paper, our method is run using Google Scholar, but the underlying filters can be easily applied to any existing publication search engine. When compared against a manually constructed data set of individuals and their publication-citation records, our method provides significant improvements over raw search results. The estimated publication-citation records returned by our method have an average sensitivity of 98% and specificity of 72% (in contrast to raw search result specificity of less than 10%. When citation indices are computed using these records, the estimated indices are within of the true value 10%, compared to raw search results which have overestimates of, on average, 75%. CONCLUSIONS: These results confirm that our method provides

As research in Earth Science becomes more data intensive, a critical requirement of data archives is that data needs to be easily discovered, accessed, and used. One approach to improving data discovery and access is through data citations coupled with Digital Object Identifiers (DOI). Beginning in 1998, the Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) has issued data product citations that have been accepted and used in AGU and other peer-reviewed journals. Citation elements established by the ORNL DAAC are similar to those used for journal articles (authors, titles, information to locate, and version), and beginning in 2007 included a DOI that is persistent, actionable, specific, and complete. The citation approach used at the DAAC also allows for referring to specific subsets of the data, by including within the citation the temporal and spatial portions of the data actually used. Citations allow others to find data and reproduce the results of the research article, and also use those data to test new hypotheses, design new sample collections, or construct or evaluate models. In addition to enhancing discovery and access of the data used in a research article, the citation gives credit to data generators, data centers and their funders, and, through citation indices, determine the scientific impact of a data set. The ORNL DAAC has developed a database that links research articles and their use of ORNL DAAC data products. The database allows determination of who, in which journal, and how the data have been used, in a manner analogous to author citation indices. The ORNL DAAC has been an initial contributor to the Thomson Reuters Data Citation Index. In addition, research data products deposited at the ORNL DAAC are linked using DOIs to relevant articles in Elsevier journals available on ScienceDirect. The ultimate goal of this implementation is that citations to data products become a routine part of the scientific process.

Open Access Papers Have a Greater Citation Advantage in the Author-Pays Model

Elaine Sullo

2016-03-01

Full Text Available Objective – To investigate the citation performance of open access (OA and toll access (TA papers published in author-pays open access journals. Design – Longitudinal citation analysis. Setting – Publications in Springer and Elsevier’s author-pays open access journals. Subjects – 633 journals published using the author-pays model. This model encompasses both journals where the article processing charge (APC is required and journals in which authors can request open access and voluntarily pay APCs for accepted manuscripts. Methods – The authors identified APC funded journals (journals funded by mandatory author processing charges as well as those where authors voluntarily paid a fee in order to have their articles openly accessible from both Springer and Elsevier, and analyzed papers published in these journals from 2007 to 2011. The authors excluded journals that adopted the APC model later than 2007. To identify Springer titles, the authors created a search strategy to identify open access articles in SpringerLink. A total of 576 journals were identified and double checked in the Sherpa-Romeo database (a database of copyright and open access self-archiving policies of academic journals to verify their open access policies. The authors then downloaded the journal content using SpringerLink, and using Springer Author-Mapper, separated out the open access articles from the toll access articles. In order to identify the Elsevier APC funded journals, the authors referred to “Open Access Journal Directory: A-Z,” which contained 35 OA journals (p. 584. Once the authors consulted “Sponsored articles” issued by Elsevier and verified titles in Sherpa-Romeo, they identified 57 journals that fit the “author-pays” model. The bibliographic information was downloaded and OA articles were separated from TA articles. The authors confirmed that all journals were indeed OA publications by downloading the full-text from off-campus locations

The scientific impact of nations: journal placement and citation performance.

Directory of Open Access Journals (Sweden)

Matthew J Smith

Full Text Available International collaboration is becoming increasingly important for the advancement of science. To gain a more precise understanding of how factors such as international collaboration influence publication success, we divide publication success into two categories: journal placement and citation performance. Analyzing all papers published between 1996 and 2012 in eight disciplines, we find that those with more countries in their affiliations performed better in both categories. Furthermore, specific countries vary in their effects both individually and in combination. Finally, we look at the relationship between national output (in papers published and input (in citations received over the 17 years, expanding upon prior depictions by also plotting an expected proportion of citations based on Journal Placement. Discrepancies between this expectation and the realized proportion of citations illuminate trends in performance, such as the decline of the Global North in response to rapidly developing countries, especially China. Yet, most countries' show little to no discrepancy, meaning that, in most cases, citation proportion can be predicted by Journal Placement alone. This reveals an extreme asymmetry between the opinions of a few reviewers and the degree to which paper acceptance and citation rates influence career advancement.

A Falsification of the Citation Impediment in the Taxonomic Literature.

Steiner, Florian M; Pautasso, Marco; Zettel, Herbert; Moder, Karl; Arthofer, Wolfgang; Schlick-Steiner, Birgit C

2015-09-01

Current science evaluation still relies on citation performance, despite criticisms of purely bibliometric research assessments. Biological taxonomy suffers from a drain of knowledge and manpower, with poor citation performance commonly held as one reason for this impediment. But is there really such a citation impediment in taxonomy? We compared the citation numbers of 306 taxonomic and 2291 non-taxonomic research articles (2009-2012) on mosses, orchids, ciliates, ants, and snakes, using Web of Science (WoS) and correcting for journal visibility. For three of the five taxa, significant differences were absent in citation numbers between taxonomic and non-taxonomic papers. This was also true for all taxa combined, although taxonomic papers received more citations than non-taxonomic ones. Our results show that, contrary to common belief, taxonomic contributions do not generally reduce a journal's citation performance and might even increase it. The scope of many journals rarely featuring taxonomy would allow editors to encourage a larger number of taxonomic submissions. Moreover, between 1993 and 2012, taxonomic publications accumulated faster than those from all biological fields. However, less than half of the taxonomic studies were published in journals in WoS. Thus, editors of highly visible journals inviting taxonomic contributions could benefit from taxonomy's strong momentum. The taxonomic output could increase even more than at its current growth rate if: (i) taxonomists currently publishing on other topics returned to taxonomy and (ii) non-taxonomists identifying the need for taxonomic acts started publishing these, possibly in collaboration with taxonomists. Finally, considering the high number of taxonomic papers attracted by the journal Zootaxa, we expect that the taxonomic community would indeed use increased chances of publishing in WoS indexed journals. We conclude that taxonomy's standing in the present citation-focused scientific landscape could

Citation analysis of meta-analysis articles on posttraumatic stress disorder.

Science.gov (United States)

Liao, Xi-Ming; Chen, Ping-Yan

2011-04-01

In the past two decades enormously scientific researches on posttraumatic stress disorder (PTSD) have been undertaken and many related meta-analyses have been published. Citation analysis was used to get comprehensive perspectives of meta-analysis articles (MA articles) on PTSD for the purpose of facilitating the researchers, physicians and policy-makers to understand the PTSD. MA articles on PTSD in any languages from January 1980 to March 2009 were included if they presented meta-analytical methods and received at least one citation recorded in the Web of Science (WoS). Whereas studies, in which any effect sizes of PTSD were not distinguished from other psychological disorders, were excluded. Citations to and by identified MA articles were documented basing on records in WoS. Citation analysis was used to examine distribution patterns of characteristics and citation impact of MA articles on PTSD. Canonical analysis was used to explore the relationship between the characteristics of MA articles and citation impact. Thirty-four MA articles published during 1998 and 2008 were identified and revealed multiple study topics on PTSD: 10 (29.4%) were about epidemiology, 13 (38.2%) about treatment or intervention, 6 (17.6%) about pathophysiology or neurophysiology or neuroendocrine, 3 (8.8%) about childhood and 2 (5.9%) about psychosocial adversity. Two articles cited most frequently with 456 and 145 counts were published in Journal of Consulting and Clinical Psychology by Brewin (2000) and Psychological Bulletin by Ozer (2003), respectively. Mean cited count was 7.48 ± 10.56 and mean age (year 2009 minus article publication year) was (4.24 ± 2.91) years. They had been cited approximately by 67 disciplines and by authors from 42 countries or territories. Characteristics of meta-analysis highly correlated with citation impact and reflected by canonical correlation of 0.899 (P < 0.000 01). The age of MA articles predicted their citation impact. Citation analysis would

Kwang-Young Kim

2013-06-01

Full Text Available Today, citation index information is used as an outcome scale of spreading technology and encouraging research. Article citation information is an important factor to determine the authority of the relevant author. Google Scholar uses the article citation information to organize academic article search results with a rank algorithm. For an accurate analysis of such important citation index information, large amounts of bibliographic data are required. Therefore, this study aims to build a fast and efficient system for large amounts of bibliographic data, and to design and develop a system for quickly analyzing cited information for that data. This study also aims to use and analyze citation data to be a basic element for providing various advanced services to the academic article search system.

[The first deontology dissertation in Croatia (Desković, 1943)].

Science.gov (United States)

Segota, I

1995-01-01

The first Croatian deontological dissertation, and probably one of the oldest in Europe, was written in Vienna in 1843. It was also published there in German. Our medical historians discovered it 40 years ago. However, its contents have up to now been unknown to our scientific and broader community. The manuscript, titled "About Physician's Duties to the State and to his Fellow-Men" (in German original: Joseph Descovich, Ueber die Pflichten des Artzes, Gegen den Staat uind seine Mitmenschen), is the work of a Dalmatian physician from Omis, Dr. Josip Desković. Nowadays when medical ethics has evolved into an independent academic discipline, and is rapidly spreading on all continents, this dissertation indicates that historical roots of medical ethics in Croats are by more than 150 years older compared to some other European countries, e. g. Sweden. The author presents the content of the dissertation and analyses it from ethical and sociological viewpoints. He relates it to Hippocratic ethics as well as to contemporary medical ethics termed bioethics, which is steadily establishing itself in modern medicine.

Wright, Kath; Golder, Su; Rodriguez-Lopez, Rocio

2014-06-03

The value of citation searches as part of the systematic review process is currently unknown. While the major guides to conducting systematic reviews state that citation searching should be carried out in addition to searching bibliographic databases there are still few studies in the literature that support this view. Rather than using a predefined search strategy to retrieve studies, citation searching uses known relevant papers to identify further papers. We describe a case study about the effectiveness of using the citation sources Google Scholar, Scopus, Web of Science and OVIDSP MEDLINE to identify records for inclusion in a systematic review.We used the 40 included studies identified by traditional database searches from one systematic review of interventions for multiple risk behaviours. We searched for each of the included studies in the four citation sources to retrieve the details of all papers that have cited these studies.We carried out two analyses; the first was to examine the overlap between the four citation sources to identify which citation tool was the most useful; the second was to investigate whether the citation searches identified any relevant records in addition to those retrieved by the original database searches. The highest number of citations was retrieved from Google Scholar (1680), followed by Scopus (1173), then Web of Science (1095) and lastly OVIDSP (213). To retrieve all the records identified by the citation tracking searching all four resources was required. Google Scholar identified the highest number of unique citations.The citation tracking identified 9 studies that met the review's inclusion criteria. Eight of these had already been identified by the traditional databases searches and identified in the screening process while the ninth was not available in any of the databases when the original searches were carried out. It would, however, have been identified by two of the database search strategies if searches had been

2013-07-01

A recent review of technical editing of research suggests that over one third of references cited in articles in medical journals have some inaccuracies and one fifth of quotations to references in these articles are not accurate. Two hundred and forty-nine citation references and 408 quotes from 25 articles published in 5 orthopaedic journals were randomly selected to determine referencing accuracy. The presence of citation errors was examined by 1 of the authors while the presence of quotation errors was determined by 2 of the authors. Full copies of articles as well as the references were obtained to compare the accuracies. The total citation error rate was 41% (103 out of 249 references), and the total quotation error rate was 20% (80 out of 408 quotes) for the 5 orthopaedic journals. Citation and quotation errors were still relatively common in orthopaedic journals. While we did not identify any factors associated with citation and quotation errors, the use of technical editing may reduce the amount of citation errors. Readers and authors should be aware that many citations of studies are inaccurate and one should review the original source if it is to be used in another publication or to guide clinical treatment.

We wanted to analyze the citation trend and to find a way to improve the impact factor (IF) of the Journal of the Korean Radiological Society (JKRS). The number of articles and references, the total citations and self-citations, the IF and the IF excluding self-citations (ZIF) were described by an analysis of Korean Medical Citation Index (KoMCI) during 2000-2005. The total and self citations of the JKRS were compared to that of the Top 5 journals. There was a 57% decrease of papers for 6 years. The Korean references/paper ranged from 0.98-0.85. The number of total citations received steadily decreased from 394 in 2000 to 180 in 2005. The IF (ZF) of the JKRS has been gradually lowered from 0.142 (0.049) in 2000 to 0.063 (0.059) in 2005. Although the total citations that cited all papers published/the annual number of papers was 55% of that of the top 5 journals, the total citations citing papers published within the recent two years was only 24% of that of the top 5 journals. The citation status of the JKRS has steadily decreased for the recent 6 years, and the IF of the JKRS was very low among all the Korean medical journals. To improve the IF, active advertising for the journal members of the importance of the IF is needed to encourage citing JKRS papers that have been published within the recent two years

Haslam, Nick; Koval, Peter

2010-06-01

The citation impact of a comprehensive sample of articles published in social and personality psychology journals in 1998 was evaluated. Potential predictors of the 10-yr. citation impact of 1580 articles from 37 journals were investigated, including number of authors, number of references, journal impact factor, author nationality, and article length, using linear regression. The impact factor of the journal in which articles appeared was the primary predictor of the citations that they accrued, accounting for 30% of the total variance. Articles with greater length, more references, and more authors were cited relatively often, although the citation advantage of longer articles was not proportionate to their length. A citation advantage was also enjoyed by authors from the United States of America, Canada, and the United Kingdom. 37% of the variance in the total number of citations was accounted for by the study variables.

Sember, Marijan; Utrobicić, Ana; Petrak, Jelka

2010-04-01

To analyze the 2007 citation count of articles published by the Croatian Medical Journal in 2005-2006 based on data from the Web of Science, Scopus, and Google Scholar. Web of Science and Scopus were searched for the articles published in 2005-2006. As all articles returned by Scopus were included in Web of Science, the latter list was the sample for further analysis. Total citation counts for each article on the list were retrieved from Web of Science, Scopus, and Google Scholar. The overlap and unique citations were compared and analyzed. Proportions were compared using chi(2)-test. Google Scholar returned the greatest proportion of articles with citations (45%), followed by Scopus (42%), and Web of Science (38%). Almost a half (49%) of articles had no citations and 11% had an equal number of identical citations in all 3 databases. The greatest overlap was found between Web of Science and Scopus (54%), followed by Scopus and Google Scholar (51%), and Web of Science and Google Scholar (44%). The greatest number of unique citations was found by Google Scholar (n=86). The majority of these citations (64%) came from journals, followed by books and PhD theses. Approximately 55% of all citing documents were full-text resources in open access. The language of citing documents was mostly English, but as many as 25 citing documents (29%) were in Chinese. Google Scholar shares a total of 42% citations returned by two others, more influential, bibliographic resources. The list of unique citations in Google Scholar is predominantly journal based, but these journals are mainly of local character. Citations received by internationally recognized medical journals are crucial for increasing the visibility of small medical journals but Google Scholar may serve as an alternative bibliometric tool for an orientational citation insight.

Predictors of Citation Rate in Psychology: Inconclusive Influence of Effect and Sample Size.

Science.gov (United States)

Hanel, Paul H P; Haase, Jennifer

2017-01-01

In the present article, we investigate predictors of how often a scientific article is cited. Specifically, we focus on the influence of two often neglected predictors of citation rate: effect size and sample size, using samples from two psychological topical areas. Both can be considered as indicators of the importance of an article and post hoc (or observed) statistical power, and should, especially in applied fields, predict citation rates. In Study 1, effect size did not have an influence on citation rates across a topical area, both with and without controlling for numerous variables that have been previously linked to citation rates. In contrast, sample size predicted citation rates, but only while controlling for other variables. In Study 2, sample and partly effect sizes predicted citation rates, indicating that the relations vary even between scientific topical areas. Statistically significant results had more citations in Study 2 but not in Study 1. The results indicate that the importance (or power) of scientific findings may not be as strongly related to citation rate as is generally assumed.

Reiter, Ofer; Mimouni, Michael; Mimouni, Daniel

2016-09-01

Concerns have been raised regarding the impact factor's (IF) accuracy and credibility, which may be affected by different factors, including self-citations. To investigate the self-citation rate (SCR) of dermatology journals and its relationship to the IF. Data on all dermatology journals listed in the Journal Citation Reports (JCR) were retrieved, and the following parameters were analyzed: IF, total publications used to calculate the IF, total citations used to calculate the IF, self-citations used to calculate the IF, SCR, and IF without self-citations (corrected IF). The median SCR was 10.53% (0-50%), and the median IF and corrected IF, 1.54 (0.05-6.37) and 1.35 (0.03-5.84), respectively. There was an inverse correlation between the IF and the SCR. A statistically significant difference was noted in the SCR between general and subspecialty journals and between journals that offered a full English text and those that did not. In general, the IF of dermatology journals is not influenced by the SCR. However, journals with a lower IF tend to have a higher SCR. Subspecialty journals and foreign language journals have a higher SCR than general dermatology and English language journals, respectively, probably owing to their limited distribution and the difficulty experienced by international authors in accessing references in specific languages. © 2015 The International Society of Dermatology.

Book citations: influence of epidemiologic thought in the academic community

Porta Miquel

2006-01-01

Full Text Available Whilst their 'death' has often been certified, books remain highly important to most professions and academic disciplines. Analyses of citations received by epidemiologic texts may complement other views on epidemiology. The objective was to assess the number of citations received by some books of epidemiology and public health, as a first step towards studying the influence of epidemiological thought and thinking in academia. For this purpose, Institute for Scientific Information/ Thomson Scientific - Web of Science/ Web of Knowledgedatabase was consulted, in May 2006. The book by Rothman & Greenland appeared to have received the highest number of citations overall (over 8,000 and per year. The books by Kleinbaum et al, and by Breslow & Day received around 5,000 citations. In terms of citations per year the book by Sackett et al ranks 3rd, and the one by Rose, 4th of those included in this preliminary study. Other books which were influential in the classrooms collected comparatively less citations. Results offer a rich picture of the academic influences and trends of epidemiologic methods and reasoning on public health, clinical medicine and the other health, life and social sciences. They may contribute to assess epidemiologists' efforts to demarcate epidemiology and to assert epistemic authority, and to analyze some historical influences of economic, social and political forces on epidemiological research.

Developing Data Citations from Digital Object Identifier Metadata

Science.gov (United States)

Wanchoo, L.; James, N.

2015-12-01

NASA's Earth Science Data and Information System (ESDIS) Project has been processing information for the registration of Digital Object Identifiers (DOI) for the last five years of which an automated system has been in operation for the last two years. The ESDIS DOI registration system has registered over 2000 DOIs with over 1000 DOIs held in reserve until all required information has been collected. By working towards the goal of assigning DOIs to the 8000+ data collections under its management, ESDIS has taken the first step towards facilitating the use of data citations with those products. When registering DOIs, ESDIS requires certain DOI elements be collected for the DOI landing page as recommended by NASA's Earth Science Data System Working Group (ESDSWG). The landing page provides sufficient information to 1) identify NASA data as referenced in a science publication, 2) credit data creators and distributors, and 3) access the data itself enabling the trace-ability and reproducibility of the data. However, the required elements for this DOI landing page are also the core required elements for forming an Earth science data citation. Data citations are getting significant attention from the scientific community and data centers alike. So to encourage the citing of Earth science data products, each product DOI landing page displays a sample data citation and makes the required citation elements available to DataCite for use in its Data Citation generation tool. This paper will describe that process. ESDIS data centers are constantly developing technologies to better serve the Earth science user community such as Geospatial Interactive Online Visualization ANd aNalysis Infrastructure (GIOVANNI), Land and Atmospheric Near Real-Time Capability for EOS (LANCE), and advanced tools that support virtual data collections, and virtual data products. These all provide easier access to data and make possible the creation of data products with user specified parameters

2014-09-01

The preferential citation of studies with the highest success rates could exaggerate perceived effectiveness, particularly for treatments with widely varying published success rates such as radiofrequency catheter ablation for atrial fibrillation. We systematically identified observational studies and clinical trials of radiofrequency catheter ablation of atrial fibrillation between 1990 and 2012. Generalized Poisson regression was used to estimate association between study success rate and total citation count, adjusting for sample size, journal impact factor, time since publication, study design, and whether first or last author was a consensus-defined pre-eminent expert. We identified 174 articles meeting our inclusion criteria (36 289 subjects). After adjustment only for time since publication, a 10-point increase above the mean in pooled reported success rates was associated with a 17.8% increase in citation count at 5 years postpublication (95% confidence interval, 7.1-28.4%; Pcitation count; 95% confidence interval, 7.6-29.6%; Pcitation count, which may indicate citation bias. To readers of the literature, radiofrequency catheter ablation of atrial fibrillation could be perceived to be more effective than the data supports. These findings may have implications for a wide variety of novel cardiovascular therapies. © 2014 American Heart Association, Inc.

Citation Analysis for the Modern Instructor: An Integrated Review of Emerging Research

Chris Piotrowski

2013-07-01

Full Text Available While online instructors may be versed in conducting e-Research (Hung, 2012; Thelwall, 2009, today’s faculty are probably less familiarized with the rapidly advancing fields of bibliometrics and informetrics. One key feature of research in these areas is Citation Analysis, a rather intricate operational feature available in modern indexes such as Web of Science, Scopus, Google Scholar, and PsycINFO. This paper reviews the recent extant research on bibliometrics within the context of citation analysis. Particular focus is on empirical studies, review essays, and critical commentaries on citation-based metrics across interdisciplinary academic areas. Research that relates to the interface between citation analysis and applications in higher education is discussed. Some of the attributes and limitations of citation operations of contemporary databases that offer citation searching or cited reference data are presented. This review concludes that: a citation-based results can vary largely and contingent on academic discipline or specialty area, b databases, that offer citation options, rely on idiosyncratic methods, coverage, and transparency of functions, c despite initial concerns, research from open access journals is being cited in traditional periodicals, and d the field of bibliometrics is rather perplex with regard to functionality and research is advancing at an exponential pace. Based on these findings, online instructors would be well served to stay abreast of developments in the field.

CITATION ANALYSIS OF URBAN PLANNING SCHOLARS IN THE U.S.

Directory of Open Access Journals (Sweden)

Sanchez Thomas W

2015-03-01

Full Text Available This article provides a complete citation analysis for the field of urban planning in the U.S. Urban planning is multi-disciplinary with a rich tradition of debate about the knowledge domain of both research and practice. Urban planning includes consideration of social, economic, technological, environmental, and political systems that are highly sophisticated, which therefore has an extensive body of scholarship. The article argues that Google Scholar is an appropriate source of citation data for urban planning and includes a brief example of one urban planning scholar to demonstrate GS citation patterns. This is followed by the results of a descriptive analysis showing general patterns of citation activity for urban planning schools. A greater depth of analysis is required to better understand the dynamics of these scholarly activities.

PREP-45, Input Preparation for CITATION-2

International Nuclear Information System (INIS)

Ramalho Carlos, C.A.

1995-01-01

1 - Description of program or function: A Fortran program has been created, which saves much effort in preparing sections 004 (intervals in the coordinates) and 005 (zone numbers) of the input data file for the multigroup theory code CITATION (version CITATION-2, NESC0387/09), particularly when a thin complicated mesh is used. 2 - Method of solution: A domain is defined for CITATION calculations through specifying its sub-domains (e.g. graphite, lead, beryllium, water and fuel sub-domains) in a compact and simple way. An independent and previous geometrical specification is made of the various types of elements which are envisaged to constitute the contents of the reactor core grid positions. Then the load table for the configuration is input and scanned throughout, thus enabling the geometric mesh description to be produced (section 004). Also the zone placement (section 005) is achieved by means of element description subroutines for the different types of element (which may require appropriate but simple changes in the actual cases). The output of PREP45 is directly obtained in a format which is compatible with CITATION-2 input. 3 - Restrictions on the complexity of the problem: Only rectangular two-dimensional Cartesian coordinates are considered. A maximum of 12 sub-domains in the x direction (18 in the y direction) and up to 8 distinct element types are considered in this version. Other limitations exist which can nevertheless be overcome with simple changes in the source program

[Analysis of citations and national and international impact factor of Farmacia Hospitalaria (2001-2005)].

Aleixandre-Benavent, R; González Alcaide, G; Miguel-Dasit, A; González de Dios, J; de Granda Orive, J I; Valderrama Zurián, J C

2007-01-01

The objective of this study is to analyse the citation patterns and impact and immediacy indicators of the Farmacia Hospitalaria journal during the period 2001-2005. An analysis of citations chosen from 101 Spanish health science journals was carried out in order to determine the citing and cited journals and the national and international impact and immediacy indicators. A similar methodology used by Thomson ISI in Science Citation Index (SCI) and Journal Citation Reports (JRC) was applied. Farmacia Hospitalaria made 1,370 citations to 316 different journals. The percentage of self-citations was 9%. The national impact factor increased from 0.178 points in 2001 to 0.663 points in 2005 while the international impact factor increased from 0.178 to 0.806 for the same period. The analysis of citation patterns demonstrates the multidisciplinary nature of Farmacia Hospitalaria and a significant growth in the impact indicators over recent years. These indicators are higher than those of some other pharmacy journals included in Journal Citation Reports. Self-citation was not excessive and was similar to that of other journals.

Data Citation Standard: A Means to Support Data Sharing, Attribution, and Traceability

Directory of Open Access Journals (Sweden)

McCallum I.

2013-04-01

Full Text Available An important incentive for scientists and researchers is the recognition and renown given to them in citations of their work. While citation rules are well developed for the use of papers published by others, very little rules are available for the citation of data made available by others. Increasingly, citation of the source of data is also requested in the context of socially relevant topics, such as climate change and its potential impacts. Providing means for data citation would be a strong incentive for data sharing. Georeferenced data are crucial for addressing many of the burning societal problems and to support related interdisciplinary research. The lack of a widely accepted method for giving credit to those who make their data freely available and for tracking the use of data throughout their life-cycle hampers data sharing. Furthermore, only clear and transparent data citation allows other scientists to obtain the identical data to replicate findings or for further research.

Modeling nonuniversal citation distributions: the role of scientific journals

International Nuclear Information System (INIS)

Yao, Zheng; Peng, Xiao-Long; Xu, Xin-Jian; Zhang, Li-Jie

2014-01-01

Whether a scientific paper is cited is related not only to the influence of its author(s) but also to the journal publishing it. Scientists, either proficient or less experienced, usually submit their most important work to prestigious journals which receive more citations than others. How to model the role of scientific journals in citation dynamics is of great importance. In this paper we address this issue through two approaches. One is the intrinsic heterogeneity of a paper determined by the impact factor of the journal publishing it. The other is the mechanism of a paper being cited which depends on its citations and prestige. We develop a model for citation networks via an intrinsic nodal weight function and an intuitive aging mechanism. The node’s weight is drawn from the distribution of impact factors of journals and the aging transition is a function of the citation and the prestige. The node-degree distribution of resulting networks shows nonuniversal scaling: the distribution decays exponentially for small degree and has a power-law tail for large degree, hence the dual behavior. The higher the impact factor of the journal, the larger the tipping point and the smaller the power exponent that are obtained. With the increase of the journal rank, this phenomenon will fade and evolve to pure power laws. (paper)

Objective: To study the information absorbency of Chinese Journal of Radiation Oncology and it's half-citing life, find out the core journals and characteristics of literature requested by scientists, and analyze the trend of Radiation Oncology research. Methods: The citation analysis is used to analyze the references cited in 475 articles in Chinese Journal of Radiation Oncology from 2001-2004. Results: Citation rate is 70.5%, and there are 8.6 citations per article. Main types of citations are journals (91.7%) and books (7.8%). The Price Index is 41.6%, and the self-citation rate is 6.2%. The percent of citations from the high-ranked 20 journals are 57.0%. Conclusions: The articles in Chinese Journal of Radiation Oncology concern most journals in the medicine, the most citations are from the English journals. The half-citing life becomes longer than research in 2003. It shows that the use of newly-published articles should be improved. (authors)

A century of citation classics in otolaryngology-head and neck surgery journals revisited.

Coelho, Daniel H; Edelmayer, Luke W; Fenton, John E

2014-06-01

Citation classics have traditionally been defined in the smaller medical specialties as any article published in a peer-reviewed journal that has received 100 or more citations from other articles also published in peer-reviewed journals. This study aimed to determine patterns of citation classics changes in the medical field otorhinolaryngology and head and neck surgery (OHNS) over the past decade and serves as a follow-up to an original study published in 2002, "A Century of Citation Classics in Otolaryngology-Head & Neck Surgery." Bibliometric analysis. Using the Journal Citation Reports and Web of Science, OHNS journals were selected and assessed for the content of citation classics. Nine-hundred five citation classics were found, over 11-fold more than 1 decade prior. Other significant changes were seen in country of origin, decade of publication, number of authors per article, subspecialty of article, and most frequently discussed topics. The dramatic rise in quantity and nature of citation classics in the past decade may be due to unprecedented advancements in information technology and communication, allowing studies and experiments to be performed, written, reviewed, published, and cited at rapid rates.

Bai, Xiaomei; Zhang, Fuli; Hou, Jie; Lee, Ivan; Kong, Xiangjie; Tolba, Amr; Xia, Feng

2018-01-01

Quantifying the impact of a scholarly paper is of great significance, yet the effect of geographical distance of cited papers has not been explored. In this paper, we examine 30,596 papers published in Physical Review C, and identify the relationship between citations and geographical distances between author affiliations. Subsequently, a relative citation weight is applied to assess the impact of a scholarly paper. A higher-order weighted quantum PageRank algorithm is also developed to address the behavior of multiple step citation flow. Capturing the citation dynamics with higher-order dependencies reveals the actual impact of papers, including necessary self-citations that are sometimes excluded in prior studies. Quantum PageRank is utilized in this paper to help differentiating nodes whose PageRank values are identical.

Does Self-Citation Influence Quantitative Measures of Research Productivity Among Academic Oral and Maxillofacial Surgeons?

Science.gov (United States)

Susarla, Srinivas M; Swanson, Edward W; Lopez, Joseph; Peacock, Zachary S; Dodson, Thomas B

2015-10-01

Quantitative measures of research productivity depend on the citation frequency of a publication. Citation-based metrics, such as the h-index (total number of publications h that have at least h citations), can be susceptible to self-citation, resulting in an inflated measure of research productivity. The purpose of the present study was to estimate the effect of self-citation on the h-index among academic oral and maxillofacial surgeons (OMSs). The present study was a cross-sectional study of full-time academic OMSs in the United States. The predictor variable was the frequency of self-citation. The primary outcome of interest was the h-index. Other study variables included demographic factors and citation metrics. Descriptive, bivariate, and regression statistics were computed. The study sample consisted of 325 full-time academic OMSs. Most surgeons were men (88.3%); approximately 40% had medical degrees. The study subjects had an average of 23.5 ± 37.1 publications. The mean number of self-citations was 15 + 56. The sample's mean h-index was 6.6 ± 7.6 and was associated with self-citation (r = 0.71, P citations. After adjusting for PhD degree, total number of publications, and academic rank, an increasing self-citation rate influenced the h-index (r = 0.006, P citations were more likely to have their h-index influenced by self-citation. Self-citation among full-time academic OMSs does not substantially affect the h-index. Surgeons in the top quartile of self-citation rates are more likely to influence their h-index.

Cheng, Kristie L; Dodson, Thomas B; Egbert, Mark A; Susarla, Srinivas M

2017-07-01

Citation rate is one of several tools to measure academic productivity. The purposes of this study were to estimate and identify factors associated with citation rates in the oral and maxillofacial surgery (OMS) literature. This was a retrospective longitudinal study of publications in the Journal of Oral and Maxillofacial Surgery (JOMS), International Journal of Oral and Maxillofacial Surgery (IJOMS), and Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology (OOOO) from January through December 2012. The predictor variables were author- and article-specific factors. The outcome variable was the citation rate, defined as the total number of citations for each article over a 4-year period. Descriptive, bivariate, and multiple regression statistics were computed. The authors identified 993 articles published during 2012. The mean number of citations at 4 years after publication was 5.6 ± 5.3 (median, 4). In bivariate analyses, several author- and article-specific factors were associated with citation rates. In a multiple regression model adjusting for potential confounders and effect modifiers, first author H-index, number of authors, journal, OMS focus area, and Oxford level of evidence were significantly associated with citation rate (P ≤ .002). The authors identified 5 factors associated with citation rates in the OMS literature. These factors should be considered in context when evaluating citation-based metrics for OMS. Studies that focus on core OMS procedures (eg, dentoalveolar surgery, dental implant surgery), are published in specialty-specific journals (eg, JOMS or IJOMS), and have higher levels of evidence are more likely to be cited.

A review on citation amnesia in depression and inflammation research.

Science.gov (United States)

Maes, Michael

2015-01-01

Once original scientific results are published the author has the "intellectual property" and may claim ownership. Discovery credit is one of the most important "rewards" for scientists and thus incorrect credits undermine the reward system of science. Scientists who publish should therefore give proper credit and acknowledge the primary sources. Failure to do so is regarded as "citation negligence", "the disregard syndrome", "citation amnesia", "plagiarism by omission", "bibliographic plagiarism" or "citation plagiarism", and may range from an unconscious or conscious "failure to credit a prior discoverer so as to give an improper impression of priority" to "the appropriation of another person's ideas or results without given proper credit". False discovery credit is considered to be "a menace to honest science", "a serious transgression" or "intellectual theft, be it intentional or not". This paper describes some examples of citation amnesia showing that scientists often fail to credit prior sources and give false discovery credit to other scientists. One example is the association between major depression and activated immuno-inflammatory pathways, a discovery by European groups and published in many papers since 1990. Now, 25 years later, it is commonplace that these theories are credited to secondary American sources whose work in "the last decade", did or did not examine these pathways in major depression. This gives an improper impression of priority of American-based scientists. Here it is proposed that this citation amnesia and plagiarism reinforced the wrong science and had negative effects on the development of immune-inflammatory biomarkers and new immune-related treatments for depression. It is concluded that journal editors should improve their citation standards to guarantee correct assignment of discovery credit for example by demanding a signed pledge from the authors that correct citations to the primary sources were made.

Currencies of Science: discussing disciplinary “exchange rates” for citations and Mendeley readership

Energy Technology Data Exchange (ETDEWEB)

Costas, R.; Perianes-Rodriguez, A.; Ruiz-Castillo, J.

2016-07-01

In 1998 Garfield stated that “[t]he Mertonian description of normal science describes citations as the currency of science. Scientists make payments, in the form of citations, to their preceptors”. The idea of citations as a currency of science was also discussed by Wouters (1999) who suggested that the “role of the citation might also be compared with that of money, especially if the evaluative use of scientometrics is taken into account. Whenever the value of an article is expressed in its citation frequency, the citation is probably the most important unit of a ‘currency of science’”. Thus, citations have been seen as currency able to reward scientists for their work and scientific merit, being an integral part, together with authorship and acknowledgements, of the so-called “reward triangle” (Cronin & Weaver, 1995)2. This role of citations as main currency in evaluative scientometrics has gone unchallenged until recently. The emergence of new ways of measuring the reception of scientific publications by different audiences in the form of the so-called “altmetrics” (Haustein, et al. 2015a; Priem, et al. 2010) probably represents the most important attempt of expanding the system of currencies of science. However, research on altmetrics suggest that there are critical differences with citations: in coverage (Thelwall, et al. 2013), main characteristics (Haustein, et al., 2015), correlations (Costas, et al. 2015b; Haustein, et al. 2014), and interpretation (Haustein et al., 2016). These results essentially highlight the limited potential of most of these metrics as realistic alternatives to citations. (Author)

Radioactive mineral occurences of Colorado and bibliography. [2500 citations in bibliography

Nelson-Moore, J.L.; Collins, D.B.; Hornbaker, A.L.

1978-01-01

This two-part report provides an essentially complete listing of radioactive occurrences in Colorado, with a comprehensive bibliography and bibliographic cross-indexes. Part 1 lists approximately 3000 known radioactive occurrences with their locations and brief accounts of the geology, mineralogy, radioactivity, host rock, production data, and source of data for each. The occurrences are classified by host rock and plotted on U.S. Geological Survey 1/sup 0/ x 2/sup 0/ topographic quadrangle maps with a special 1 : 100,000-scale base map for the Uravan mineral belt. Part 2 contains the bibliography of approximately 2500 citations on radioactive mineral occurrences in the state, with cross-indexes by county, host rock, and the special categories of ''Front Range,'' ''Colorado Plateau,'' and ''thorium.'' The term ''occurrence'' as used in this report is defined as any site where the concentration of uranium or thorium is at least 0.01% or where the range of radioactivity is greater than twice the background radioactivity. All citations and occurrence data are stored on computer diskettes for easy retrieval, correction, and updating.

Power laws in citation distributions: evidence from Scopus.

Science.gov (United States)

Brzezinski, Michal

Modeling distributions of citations to scientific papers is crucial for understanding how science develops. However, there is a considerable empirical controversy on which statistical model fits the citation distributions best. This paper is concerned with rigorous empirical detection of power-law behaviour in the distribution of citations received by the most highly cited scientific papers. We have used a large, novel data set on citations to scientific papers published between 1998 and 2002 drawn from Scopus. The power-law model is compared with a number of alternative models using a likelihood ratio test. We have found that the power-law hypothesis is rejected for around half of the Scopus fields of science. For these fields of science, the Yule, power-law with exponential cut-off and log-normal distributions seem to fit the data better than the pure power-law model. On the other hand, when the power-law hypothesis is not rejected, it is usually empirically indistinguishable from most of the alternative models. The pure power-law model seems to be the best model only for the most highly cited papers in "Physics and Astronomy". Overall, our results seem to support theories implying that the most highly cited scientific papers follow the Yule, power-law with exponential cut-off or log-normal distribution. Our findings suggest also that power laws in citation distributions, when present, account only for a very small fraction of the published papers (less than 1 % for most of science fields) and that the power-law scaling parameter (exponent) is substantially higher (from around 3.2 to around 4.7) than found in the older literature.

Are there ways to improve the citations of a scientific paper?

Science.gov (United States)

Bartoli, E

2018-04-01

The expansion of scientific publications makes more difficult the mining of relevant information necessary for a productive appraisal of authors' work, scientific interaction and exchange. Papers over-citation is unproductive, under-citation of innovative research generates delay and inefficiency. The extraction of information from the literature is mostly based on keywords (KWs). I computed the chances of citation of one paper as 1/number of papers retrieved by the KWs published in that paper, and compared them with the chances obtained by selecting different KWs. Using generic KWs the chances are smaller, at times practically nil, as compared to those calculated with more specific KWs and their association. Selecting scientifically-analyzed KWs, specific for the message conveyed by a paper and computing beforehand the theoretical chances of citation, might increase the citations obtained, the retrieval of important scientific and innovative information, optimize scientific exchange and qualitative productivity.

Cite we must, cite we do. We cite because we are links in a chain, using properties and methods validated by others. We also cite to negotiate the anxiety of influence. And to be fair. After outlining the reasons for citation, we use two case studies of citation amnesia in the field of hypothetical carbon allotropes to present a computer-age search tool (SACADA) in that subsubfield. Finally, we advise on good search practice, including what to do if you miss a citation. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

[Citation analysis of research articles from Norwegian health enterprises, 2005-2011].

Science.gov (United States)

Piro, Fredrik Niclas; Aksnes, Dag W

2014-08-19

The citation frequency of a publication is often interpreted as an expression of its scientific impact. Previous citation analyses of Norwegian medical research have either focused on universities and university hospitals or on subject areas at the national level. Such analyses have paid little attention to other health enterprises, despite a strong increase in their research activity during the last decade. For all health enterprises with more than 25 publications in the Web of Science during the period 2005-2011 we have calculated field normalized citation indexes at the institution and subject levels. On the whole, research undertaken by the health enterprises is frequently cited, and some medium-sized health enterprises stand out in terms of their high average citation indexes: Helse Stavanger Health Enterprise, Diakonhjemmet Hospital and Helse Nord-Trøndelag Health Enterprise, although Oslo University Hospital Health Enterprise and Helse Bergen Health Enterprise account for more than half of the most cited articles. In citation analyses at the aggregated level, highly and infrequently cited research groups/departments may balance each other. This appears to be the case in the largest health enterprises. Some medium-sized health enterprises that have a more concentrated research portfolio will thus accumulate higher average citation indexes than the largest university hospitals.

Quantifying the impact of scholarly papers based on higher-order weighted citations

Bai, Xiaomei; Zhang, Fuli; Hou, Jie; Kong, Xiangjie; Tolba, Amr; Xia, Feng

2018-01-01

Quantifying the impact of a scholarly paper is of great significance, yet the effect of geographical distance of cited papers has not been explored. In this paper, we examine 30,596 papers published in Physical Review C, and identify the relationship between citations and geographical distances between author affiliations. Subsequently, a relative citation weight is applied to assess the impact of a scholarly paper. A higher-order weighted quantum PageRank algorithm is also developed to address the behavior of multiple step citation flow. Capturing the citation dynamics with higher-order dependencies reveals the actual impact of papers, including necessary self-citations that are sometimes excluded in prior studies. Quantum PageRank is utilized in this paper to help differentiating nodes whose PageRank values are identical. PMID:29596426

Doctoral Dissertations in the Internet: A Good Start in Finland

Esko Häkli

2000-05-01

Full Text Available At the present stage of the IT-applications the change from print publishing into electronic publishing of doctoral dissertations is not only a question of technology but it is also, and possibly even to a greater extent, a question of thinking. Although there is a large selection of technologies and publication formats available, none of them seem to be mature enough to be a self-evident choice. But obviously a greater obstacle can be found in the minds of people. In many cases legal regulations also have to be revised. Academic traditions still prefer properly printed dissertations and the attitudes of the academic community are not necessarily favourable towards electronic publishing in general. Young post-graduate students are obviously not able to appreciate a virtual dissertation. They seem to need a real tangible thing, which they also can show to their parents! And finally, the whole organization and financing of publishing may need to be revised, an exercise which is far more difficult than only starting to use new technology.

Ruano-Ravina, Alberto; Alvarez-Dardet, Carlos

2012-09-01

Citations received by papers published within a journal serve to increase its bibliometric impact. The objective of this paper was to assess the influence of publication language, article type, number of authors, and year of publication on the citations received by papers published in Gaceta Sanitaria, a Spanish-language journal of public health. The information sources were the journal website and the Web of Knowledge, of the Institute of Scientific Information. The period analyzed was from 2007 to 2010. We included original articles, brief original articles, and reviews published within that period. We extracted manually information regarding the variables analyzed and we also differentiated among total citations and self-citations. We constructed logistic regression models to analyze the probability of a Gaceta Sanitaria paper to be cited or not, taking into account the aforementioned independent variables. We also analyzed the probability of receiving citations from non-Spanish authors. Two hundred forty papers fulfilled the inclusion criteria. The included papers received a total of 287 citations, which became 202 when excluding self-citations. The only variable influencing the probability of being cited was the publication year. After excluding never cited papers, time since publication and review papers had the highest probabilities of being cited. Papers in English and review articles had a higher probability of citation from non-Spanish authors. Publication language has no influence on the citations received by a national, non-English journal. Reviews in English have the highest probability of citation from abroad. Editors should decide how to manage this information when deciding policies to raise the bibliometric impact factor of their journals. Copyright © 2012 Elsevier Inc. All rights reserved.

Study on the Promotion in the Citation of the Nuclear Engineering and Technology

International Nuclear Information System (INIS)

Chun, Young Choon; Yoo, J. B.; Yi, J. H.

2012-01-01

The Korean journal published in English, Nuclear Engineering and Technology (here under NET) has been enlisted in the global citation database SCI E(Science Citation Index Expanded) of Thomson Reuters (past ISI), beginning with NET vol.39 No.1 (Feb. 2007). As of July 2009, the citation index of NET as reported by JCR (Journal Citation Report) based on the cumulative data from ISI (Institute for Scientific Information) reached to 0.991. This index ranks on 12 th among the 33 journals in the area of nuclear science and technology in the science and technology covered by JCR, meaning fairly high impact factor. The following year 2010, however, witnessed the JCR figure dropping down to 0.465. The reason behind such drastic fall would be the decreased citation and in a lesser extent self-citation in 2010, in comparison with 2009, despite the increased number of paper publication. This study attempts to give an analysis as of the end of 2011 on the NET citation frequency in SCI Source Journal and the citation frequency by KAERI authors, together with the nationalities of NET authors and SCI journals that refer to NET most. Based on the analysis, the paper suggests some ways to promoting the position of NET as a journal in the international nuclear sector

Bibliography for transportation energy conservation. [578 citations

Energy Technology Data Exchange (ETDEWEB)

LaBelle, Sarah J.

1976-05-01

A listing is given of 578 reports, books, articles, and conference papers on transportation and energy. Coverage is primarily on U. S. developments and research from 1970 to 1975. Following a section of citations of general works on energy, the bibliography contains two main parts: ''Energy for Transportation'' and ''Transportation of Energy.'' Within each of these topics the arrangement is multimodal (at the urban, regional, national, or international level), then by mode. Selected information sources are listed in the last part. Within each section, entries are arranged alphabetically by author or, lacking an author, by title. References were drawn from the Transportation Center Library collection and other libraries in the Northwestern University system. An earlier bibliography, Transportation and Energy, compiled by the Transportation Center Library in March 1974, forms the basis for the arrangement and provides coverage from 1970 to 1973.

To characterize the dissertations and theses available in the Bank of Theses of the Coordination for the Improvement of Higher Education Personnel (CAPES) that deal with trauma. This is a documentary research on the characterization of Brazilian theses and dissertations that deal with trauma, available at the CAPES Theses Database. Data collection was carried out in March 2012, by master's degree students and PhDs, following a research protocol. A total of 411 dissertations and theses about trauma were analyzed. We elucidated considerations on the following aspects of the selected studies: academic level, location of conduction of the work, author's training, methodological design, theme and type of trauma. The significant amount of studies analyzed reveals the importance of trauma in the current scenario, the expansion of graduate programs and researchers being in line with the theme that alarmingly affects the national and international epidemiology.

[Medycyna Pracy: the scopus-based analysis of citations].

Przyłuska, Jolanta

2006-01-01

Medycyna Pracy, a Polish bimonthly published since 1950, forms a long-standing documentation of studies carried out in the area of workers' health protection. The journal is primarily addressed to occupational health physicians and work hygiene specialists in Poland. It is indexed by numerous foreign information services (e.g., MEDLINE, EMBASE, BIOSIS PREVIEWS, BIOLOGICAL ABSTRACTS, SCOPUS) and thus promotes Polish research in occupational medicine throughout the world. The quantitative analysis for the years 1996-2005, grounded on the SCOPUS database, presents an average number of citations concerning a given volume, frequency of citations, articles most frequently cited, and countries, in which articles published in Medycyna Pracy have been referred to. A growing number of citations observed in the recent years signify the importance of issues investigated and discussed in the journal as well as its role in the world-wide circulation of scientific information.

Citation Impact of Collaboration in Radiology Research.

Rosenkrantz, Andrew B; Parikh, Ujas; Duszak, Richard

2018-02-01

Team science involving multidisciplinary and multi-institutional collaboration is increasingly recognized as a means of strengthening the quality of scientific research. The aim of this study was to assess associations between various forms of collaboration and the citation impact of published radiology research. In 2010, 876 original research articles published in Academic Radiology, the American Journal of Roentgenology, JACR, and Radiology were identified with at least one radiology-affiliated author. All articles were manually reviewed to extract features related to all authors' disciplines and institutions. Citations to these articles through September 2016 were extracted from Thomson Reuters Web of Science. Subsequent journal article citation counts were significantly higher (P < .05) for original research articles with at least seven versus six or fewer authors (26.2 ± 30.8 versus 20.3 ± 23.1, respectively), with authors from multiple countries versus from a single country (32.3 ± 39.2 versus 22.0 ± 25.0, respectively), with rather than without a nonuniversity collaborator (28.7 ± 38.6 versus 22.4 ± 24.9, respectively), and with rather than without a nonclinical collaborator (26.5 ± 33.1 versus 21.9 ± 24.4, respectively). On multivariate regression analysis, the strongest independent predictors of the number of citations were authors from multiple countries (β = 9.14, P = .002), a nonuniversity collaborator (β = 4.80, P = .082), and at least seven authors (β = 4.11, P = .038). With respect to subsequent journal article citations, various forms of collaboration are associated with greater scholarly impact of published radiology research. To enhance the relevance of their research, radiology investigators are encouraged to pursue collaboration across traditional disciplinary, institutional, and geographic boundaries.

This study investigated the professional impact of "Japanese Journal of Psychology." Thirty four psychological journals written in Japanese were selected to register articles in a new database. This database included approximately 23,900 articles published through 2010. Using citations extracted from the references and footnotes in these scholarly journals, the Psychology Citation Index for Japanese Papers was created. The citation impact factors in Japanese psychology was determined on the basis of the number of times a journal was cited, cumulative impact factors, and the cited half-life of the journal; five years was a valid period for impact factor of psychological journals in Japan. The changes in the 5-year impact factors of "Japanese Journal of Psychology" were reviewed by comparing it with other journals.

Three options for citation tracking: Google Scholar, Scopus and Web of Science.

Bakkalbasi, Nisa; Bauer, Kathleen; Glover, Janis; Wang, Lei

2006-06-29

Researchers turn to citation tracking to find the most influential articles for a particular topic and to see how often their own published papers are cited. For years researchers looking for this type of information had only one resource to consult: the Web of Science from Thomson Scientific. In 2004 two competitors emerged--Scopus from Elsevier and Google Scholar from Google. The research reported here uses citation analysis in an observational study examining these three databases; comparing citation counts for articles from two disciplines (oncology and condensed matter physics) and two years (1993 and 2003) to test the hypothesis that the different scholarly publication coverage provided by the three search tools will lead to different citation counts from each. Eleven journal titles with varying impact factors were selected from each discipline (oncology and condensed matter physics) using the Journal Citation Reports (JCR). All articles published in the selected titles were retrieved for the years 1993 and 2003, and a stratified random sample of articles was chosen, resulting in four sets of articles. During the week of November 7-12, 2005, the citation counts for each research article were extracted from the three sources. The actual citing references for a subset of the articles published in 2003 were also gathered from each of the three sources. For oncology 1993 Web of Science returned the highest average number of citations, 45.3. Scopus returned the highest average number of citations (8.9) for oncology 2003. Web of Science returned the highest number of citations for condensed matter physics 1993 and 2003 (22.5 and 3.9 respectively). The data showed a significant difference in the mean citation rates between all pairs of resources except between Google Scholar and Scopus for condensed matter physics 2003. For articles published in 2003 Google Scholar returned the largest amount of unique citing material for oncology and Web of Science returned the

Citation classics represent the highest cited works in a field and are often regarded as the most influential literature. Analyzing thematic trends in citation classics across eras enables recognition of important historical advances within a field. We present the first analysis of the citation classics in neuro-oncology. The Web of Science database was searched using terms relevant to "neuro-oncology." Articles with >400 citations were identified and the top 100 cited articles were evaluated. The top 100 neuro-oncology citation classics consisted of 43 clinical studies (17 retrospective, 10 prospective, 16 randomized trials), 43 laboratory investigations, 8 reviews/meta-analyses, and 6 guidelines/consensus statements. Articles were classified into 4 themes: 13 pertained to tumor classification, 37 to tumor pathogenesis/clinical presentation, 6 to imaging, 44 to therapy (15 chemotherapy, 10 radiotherapy, 5 surgery, 14 new agents). Gliomas were the most common tumor type examined, with 70 articles. There was a significant increase in the number of citation classics in the late 1990s, which was paralleled by an increase in studies examining tumor pathogenesis, chemotherapy, and new agents along with laboratory and randomized studies. The majority of citation classics in neuro-oncology are related to gliomas and pertain to tumor pathogenesis and treatment. The rise in citation classics in recent years investigating tumor biology, new treatment agents, and chemotherapeutics may reflect increasing scientific interest in nonsurgical treatments for CNS tumors and the need for fundamental investigations into disease processes. © The Author(s) 2017.

Tweet success? Scientific communication correlates with increased citations in Ecology and Conservation

Directory of Open Access Journals (Sweden)

Clayton T. Lamb

2018-04-01

Full Text Available Science communication is seen as critical for the disciplines of ecology and conservation, where research products are often used to shape policy and decision making. Scientists are increasing their online media communication, via social media and news. Such media engagement has been thought to influence or predict traditional metrics of scholarship, such as citation rates. Here, we measure the association between citation rates and the Altmetric Attention Score—an indicator of the amount and reach of the attention an article has received—along with other forms of bibliometric performance (year published, journal impact factor, and article type. We found that Attention Score was positively correlated with citation rates. However, in recent years, we detected increasing media exposure did not relate to the equivalent citations as in earlier years; signalling a diminishing return on investment. Citations correlated with journal impact factors up to ∼13, but then plateaued, demonstrating that maximizing citations does not require publishing in the highest-impact journals. We conclude that ecology and conservation researchers can increase exposure of their research through social media engagement and, simultaneously, enhance their performance under traditional measures of scholarly activity.

To identify and analyze the characteristics of the most influential articles about central nervous system (CNS) inflammatory demyelinating disease. The Institute for Scientific Information (ISI) Web of Science database and the 2014 Journal Citation Reports Science Edition were used to retrieve the top 100 cited articles on CNS inflammatory demyelinating disease. The citation numbers, journals, years of publication, authorships, article types, subjects and main issues were analyzed. For neuromyelitis optica (NMO), articles that were cited more than 100 times were regarded as a citation classic and described separately. The top 100 cited articles were published between 1972 and 2011 in 13 journals. The highest number of articles ( n  = 24) was published in Brain, followed by The New England Journal of Medicine ( n  = 21). The average number of citations was 664 (range 330-3,897), and 64% of the articles were from the United States and the United Kingdom. The majority of the top 100 cited articles were related to multiple sclerosis ( n  = 87), and only a few articles reported on other topics such as NMO ( n  = 9), acute disseminated encephalomyelitis ( n  = 2) and optic neuritis ( n  = 2). Among the top 100 cited articles, 77% were original articles. Forty-one citation classics were found for NMO. Our study provides a historical perspective on the research progress on CNS inflammatory demyelinating disease and may serve as a guide for important advances and trends in the field for associated researchers.

Wood, L J; McLean, S; Davidson, J; Montgomery, I M

1995-01-01

Drink drivers arrested in Tasmania are routinely asked by police where they had last been drinking, and these data were examined for 716 drivers arrested in Southern Tasmania during a 4-month period in 1992. Nearly half (43%) of arrested drink drivers cited individual hotels as the place where they had last been drinking. This enabled a citation score to be assigned to each of the 82 hotels in metropolitan Hobart. The distribution of citation scores was highly skewed, with eight hotels accounting for 45% of hotel citations, and two accounting for 20%. The hotels' citation scores were compared in relation to the rank order of their licence fees, since better measures of patronage proved unobtainable. Some hotels with small total alcohol sales did appear to have an unexpectedly large number of citations, suggesting less than responsible serving practices. Hoteliers' comments were sought on the interpretation of citation scores, and incorporated into a discussion of the limitations of the data in determining the extent of individual hotel responsibility for drink drivers. Important questions remaining include (1) what is the validity of citations made by drink drivers at the time of arrest; (2) what appropriate and quantifiable denominator can be used to adjust the number of citations to the level of patronage; and (3) what level of citations is too high and requires action?

Citation practices in Slovak and English linguistic research papers

Directory of Open Access Journals (Sweden)

Walková Milada

2017-12-01

Full Text Available Citation in research articles is an important gateway to acceptance by academic community. When citing others, scholars follow the conventions of the genre, of the academic discipline, and of their culture. This paper focuses on the cultural aspects of citation by comparing and contrasting a corpus of linguistic papers written in English and in Slovak. The results show that while English native writers prefer making their papers more objective through a higher incidence of generalisations and reporting verbs denoting the process of research, Slovak native writers opt for making the cited authors more visible by a greater amount of integral citations and reporting verbs denoting mental states and processes. A higher number of quotations, including floating quotations, suggests that Slovak scholars have a high regard for the work of others.

Cardona, Genís; Sanz, Joan P

2014-09-01

This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR). The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored. Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals. These findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.

Measuring Long-Term Impact Based on Network Centrality: Unraveling Cinematic Citations

Science.gov (United States)

Spitz, Andreas; Horvát, Emőke-Ágnes

2014-01-01

Traditional measures of success for film, such as box-office revenue and critical acclaim, lack the ability to quantify long-lasting impact and depend on factors that are largely external to the craft itself. With the growing number of films that are being created and large-scale data becoming available through crowd-sourced online platforms, an endogenous measure of success that is not reliant on manual appraisal is of increasing importance. In this article we propose such a ranking method based on a combination of centrality indices. We apply the method to a network that contains several types of citations between more than 40,000 international feature films. From this network we derive a list of milestone films, which can be considered to constitute the foundations of cinema. In a comparison to various existing lists of ‘greatest’ films, such as personal favourite lists, voting lists, lists of individual experts, and lists deduced from expert polls, the selection of milestone films is more diverse in terms of genres, actors, and main creators. Our results shed light on the potential of a systematic quantitative investigation based on cinematic influences in identifying the most inspiring creations in world cinema. In a broader perspective, we introduce a novel research question to large-scale citation analysis, one of the most intriguing topics that have been at the forefront of scientific enquiries for the past fifty years and have led to the development of various network analytic methods. In doing so, we transfer widely studied approaches from citation analysis to the the newly emerging field of quantification efforts in the arts. The specific contribution of this paper consists in modelling the multidimensional cinematic references as a growing multiplex network and in developing a methodology for the identification of central films in this network.

Data citation in climate sciences: Improvements in CMIP6 compared to CMIP5

Science.gov (United States)

Stockhause, M.; Lautenschlager, M.

2017-12-01

Within CMIP5 (Coupled Model Intercomparison Project Phase 5) the citation of the data was not possible prior its long-term archival in the IPCC Data Distribution Centre (DDC). The Reference Data Archive for AR5 (Assessment Report 5) was built up after the submission deadline for part 1 of the AR5. This was too late for many scientific articles. But even the AR5 data in the IPCC DDC is rarely cited in literature in spite of annual download volumes between one and three PBytes. On the other hand, the request for a citation possibility for the evolving CMIP6 data prior to long-term archival came from the CMIP6 data providers. The additional provision of data citations for the project input4MIPs (input data for CMIP6) could raise the scientists' awareness of the discrepancy between the readiness to cite data and the desire to be cited and get credit. The CMIP6 Citation Service is a pragmatic approach built on existing services and services under development, such as ESGF (Earth System Grid Federation) as data infrastructure component, DataCite as DOI registration agency, and Scholix services for tracking data usage information. Other principles followed to overcome barriers of data citation are: Collect data and literature references in the data citation metadata to enable data-data and data-literature interlinking. Visibility of data citation information in the ESGF data portals (low barrier to access data citation information) Provide data usage information in literature for the data providers, data node managers and their funders (requested by some ESGF data node managers) The CMIP6 Citation Service is an implementation only of the credit part of the RDA WGDC recommendation for the citation of dynamic data. The second part, the identification of the data subset underlying an article, is planned for CMIP7 as a data cart approach comprising multiple pre-defined CMIP6 DataCite DOIs. Additional policies on the long-term data availability are required. References: M

Citation Analysis for Biomedical and Health Sciences Journals Published in Korea.

A citation analysis of biomedical and health sciences journals was conducted based on their enlistment in journal databases to identify the factors contributing to the citation metrics. Among the 1,219 academic journals managed by the National Center for Medical Information and Knowledge at the Korea Centers for Disease Control and Prevention, 556 journals were included for analysis as of July 2016. The characteristics of the journals include history years, publication media, language, open-access policy as well as the status enlisted in international and domestic databases, such as Science Citation Index (SCI), Scopus, Medline, PubMed Central, Embase, and Korea Citation Index (KCI). Six bibliometric measures were collected from SCI, Scopus, and KCI as of 2015, the most recent disclosure year. Analyses of group differences and influential factors were conducted using t -tests, Mann-Whitney tests, and multiple regression. Journal characteristics, such as history years, publication media, and open-access policy, were not significant factors influencing global or domestical citation of the journals. However, global citations were higher for SCI and Medline enlisted journals than for their counterparts. Among KCI journals, the KCI impact factors of journals published in English only were lower. Efforts by journals to be enlisted in international databases, especially in SCI and Medline, are critical to enhance their global circulation. However, articles published in English only hinder the use of domestic researchers. Different strategies are required for enhancing international and domestic readerships.

2015-01-01

There is a need to evaluate the quality of postgraduate dissertations of dentistry submitted to university in the light of the international standards of reporting. We conducted the review with an objective to document the use of sampling methods, measurement standardization, blinding, methods to eliminate bias, appropriate use of statistical tests, appropriate use of data presentation in postgraduate dental research and suggest and recommend modifications. The public access database of the dissertations from Rajiv Gandhi University of Health Sciences was reviewed. Three hundred and thirty-three eligible dissertations underwent preliminary evaluation followed by detailed evaluation of 10% of randomly selected dissertations. The dissertations were assessed based on international reporting guidelines such as strengthening the reporting of observational studies in epidemiology (STROBE), consolidated standards of reporting trials (CONSORT), and other scholarly resources. The data were compiled using MS Excel and SPSS 10.0. Numbers and percentages were used for describing the data. The "in vitro" studies were the most common type of research (39%), followed by observational (32%) and experimental studies (29%). The disciplines conservative dentistry (92%) and prosthodontics (75%) reported high numbers of in vitro research. Disciplines oral surgery (80%) and periodontics (67%) had conducted experimental studies as a major share of their research. Lacunae in the studies included observational studies not following random sampling (70%), experimental studies not following random allocation (75%), not mentioning about blinding, confounding variables and calibrations in measurements, misrepresenting the data by inappropriate data presentation, errors in reporting probability values and not reporting confidence intervals. Few studies showed grossly inappropriate choice of statistical tests and many studies needed additional tests. Overall observations indicated the need to

Full Text Available Paul Gavrilyuk recently reconstructed Georges Florovsky’s dissertation, “Hertsen’s Philosophy of History”, the complete text of which was previously considered lost. According to the report of Alexander Izgoev, G.V. Florovsky presented the summary of his dissertation in 19 theses during his dissertation defense in Prague on 3 June 1923. The typescript of these 19 theses, bearing the title «The Dissertation’s Theses of Privatdozent Georges Florovsky: «The Hertsen’s Philosophy of History»» was recently discovered by Matthew Baker in the Andrew Blane Papers. This document is published here for the first time. The 19 theses support the Gavrilyuk’s hypothesis that the June 1923 redaction of the dissertation consisted of an introduction, three chapters and a conclusion.

The paper analyzed the life cycle of scientific publications and show that the way to promote scientific articles in the world community inherent properties of Markov processes. Application of Markov chains allows top ground the need for active participation of the authors in the distribution of its publications in different scientometric databases, repositories of scientific and social networks. Markov model to describe decomposition of scientists made certain discrete states and proposed a schematic diagram of transitions between them. The model's 5A fully reflect the properties of the system. Communication influences the probability of changing system states with consistent movement along the trajectory from a lack of information about the publication to familiarize with it because of the positive attitude to state its citation. This is a must as well as a negative attitude to the publications. Proved that improve performance citation of scientific publications in the case of using Google Scholar, ORCID, Mendeley, Academia, ResearchGate, and others. The active participation of authors in their publications available in these systems leads to an increase in the proportion of articles that are available to colleagues in the global scientific community that is becoming one of the factors of increase in citations.

Citations are ubiquitous in scientific articles and play important roles for representing the semantic content of a full-text biomedical article. In this work, we manually examined full-text biomedical articles to analyze the semantic content of citations in full-text biomedical articles. After developing a citation relation schema and annotation guideline, our pilot annotation results show an overall agreement of 0.71, and here we report on the research challenges and the lessons we've learned while trying to overcome them. Our work is a first step toward automatic citation classification in full-text biomedical articles, which may contribute to many text mining tasks, including information retrieval, extraction, summarization, and question answering.

2012-08-31

We put under experimental scrutiny the preferential attachment model that is commonly accepted as a generating mechanism of the scale-free complex networks. To this end we chose a citation network of physics papers and traced the citation history of 40,195 papers published in one year. Contrary to common belief, we find that the citation dynamics of the individual papers follows the superlinear preferential attachment, with the exponent α=1.25-1.3. Moreover, we show that the citation process cannot be described as a memoryless Markov chain since there is a substantial correlation between the present and recent citation rates of a paper. Based on our findings we construct a stochastic growth model of the citation network, perform numerical simulations based on this model and achieve an excellent agreement with the measured citation distributions.

Revisiting an open access monograph experiment: measuring citations and tweets 5 years later.

Science.gov (United States)

Snijder, Ronald

An experiment run in 2009 could not assess whether making monographs available in open access enhanced scholarly impact. This paper revisits the experiment, drawing on additional citation data and tweets. It attempts to answer the following research question: does open access have a positive influence on the number of citations and tweets a monograph receives, taking into account the influence of scholarly field and language? The correlation between monograph citations and tweets is also investigated. The number of citations and tweets measured in 2014 reveal a slight open access advantage, but the influence of language or subject should also be taken into account. However, Twitter usage and citation behaviour hardly overlap.

Misemer, Benjamin S; Platts-Mills, Timothy F; Jones, Christopher W

Citation bias occurs when positive trials involving a medical intervention receive more citations than neutral or negative trials of similar quality. Several large clinical trials have studied the use of thrombolytic agents for the treatment of acute ischemic stroke with differing results, thereby presenting an opportunity to assess these trials for evidence of citation bias. We compared citation rates among positive, neutral, and negative trials of alteplase (tPA) and other thrombolytic agents for stroke. We used a 2014 Cochrane Review of thrombolytic therapy for the treatment of acute stroke to identify non-pilot, English-language stroke trials published in MEDLINE-indexed journals comparing thrombolytic therapy with control. We classified trials as positive if there was a statistically significant primary outcome difference favoring the intervention, neutral if there was no difference in primary outcome, or negative for a significant primary outcome difference favoring the control group. Trials were also considered negative if safety concerns supported stopping the trial early. Using Scopus, we collected citation counts through 2015 and compared citation rates according to trial outcomes. Eight tPA trials met inclusion criteria: two were positive, four were neutral, and two were negative. The two positive trials received 9080 total citations, the four neutral trials received 4847 citations, and the two negative trials received 1096 citations. The mean annual per-trial citation rates were 333 citations per year for positive trials, 96 citations per year for neutral trials, and 35 citations per year for negative trials. Trials involving other thrombolytic agents were not cited as often, though as with tPA, positive trials were cited more frequently than neutral or negative trials. Positive trials of tPA for ischemic stroke are cited approximately three times as often as neutral trials, and nearly 10 times as often as negative trials, indicating the presence of

Opthof, Tobias

2011-06-01

In this article, a critical analysis is performed on differences in citation frequency of basic and clinical cardiovascular papers. It appears that the latter papers are cited at about 40% higher frequency. The differences between the largest number of citations of the most cited papers are even larger. It is also demonstrated that the groups of clinical and basic cardiovascular papers are also heterogeneous concerning citation frequency. It is concluded that none of the existing citation indicators appreciates these differences. At this moment these indicators should not be used for quality assessment of individual scientists and scientific niches with small numbers of scientists.

"'Jackin’ for Beats'": DJing for Citation Critique

Full Text Available A challenge in teaching English composition is helping students envision plagiarism as “borrowing” – showing love to author(s and/or text(s that further their argument(s, versus “stealing” – biting someone’s style and words. Alastair Pennycook (1996 and Sarah Wakefield (2006 have contributed pieces to the elaborate plagiarism/citation puzzle, while Houston Baker situated the hip-hop DJ in seminal text Black Studies, Rap and the Academy (1993. Merging these moments introduces critical questions: Did Diddy invent “the remix” or become the illest beat-biter ever? How did DJ/Producers Pete Rock and Large Professor pay homage to previous musical genres to further hip-hop remix production without just taking 4-8 bar samples, copying sources and claiming unethical ownership? And how can this discussion provide students a window into citation conversations? This article will remix these “texts” to introduce the idea of DJ Rhetoric to discuss plagiarism. Through the lens of the hip-hop DJ in writing classrooms, one can foster an appreciation of the difference between “love and theft” in student citation. This article will couple examples from hip-hop music/culture while simultaneously remixing interviews from various hip-hop DJ/producers to help answer these difficult questions.

Scientific impact of studies published in temporarily available radiation oncology journals: a citation analysis.

Science.gov (United States)

Nieder, Carsten; Geinitz, Hans; Andratschke, Nicolaus H; Grosu, Anca L

2015-01-01

The purpose of this study was to review all articles published in two temporarily available radiation oncology journals (Radiation Oncology Investigations, Journal of Radiosurgery) in order to evaluate their scientific impact. From several potential measures of impact and relevance of research, we selected article citation rate because landmark or practice-changing research is likely to be cited frequently. The citation database Scopus was used to analyse number of citations. During the time period 1996-1999 the journal Radiation Oncology Investigations published 205 articles, which achieved a median number of 6 citations (range 0-116). However, the most frequently cited article in the first 4 volumes achieved only 23 citations. The Journal of Radiosurgery published only 31 articles, all in the year 1999, which achieved a median number of 1 citation (range 0-11). No prospective randomized studies or phase I-II collaborative group trials were published in these journals. Apparently, the Journal of Radiosurgery acquired relatively few manuscripts that were interesting and important enough to impact clinical practice. Radiation Oncology Investigations' citation pattern was better and closer related to that reported in several previous studies focusing on the field of radiation oncology. The vast majority of articles published in temporarily available radiation oncology journals had limited clinical impact and achieved few citations. Highly influential research was unlikely to be submitted during the initial phase of establishing new radiation oncology journals.

Last year's Joint Declaration of Data Citation Principles has triggered much discussion about the best ways to handle citation of data across research disciplines. Many communities have gotten together to design solutions to the issues of giving proper credit and attribution, although many fields, including solar physics, have yet to implement them. Issues still exist regarding data citation as a record for scientific reproducability.Solar physics data is particularly difficult to cite due to the nature of our collection methods and the method in which our data are used. Other than sounding rocket or balloon flights, our data collection from a given instrument spans years or decades but observing modes, cadence and field of view may vary daily. Researchers may only analyze a short timespan of the data, only given observing modes, at a slower cadence, and/or only a portion of each image; this reduction should be described to ensure that the analysis is reproducible.Many archives keep only the current, best calibrated data, making updates in place. It can be difficult to determine if the data used in a publication is the same as the currently available data.We discuss the current progress by the Research Data Alliance's Dynamic Data Citation Working Group, and tools and services that would be useful to identify when data may have been changed by an archive. As it may be some time before standards can be developed, we include a checklist for authors to improve reproducibility of their published articles.

This article examines the relative positions with respect to nanotechnology research publications of the European Union (EU), the United States (US), Japan, Germany, China, and three Asian Tiger nations (South Korea, Singapore, and Taiwan). The analysis uses a dataset of nanotechnology publication records for the time period 1990 through 2006 (part year) extracted from the Science Citation Index obtained through the Web of Science and was developed through a two-stage modularized Boolean approach. The results show that although the EU and the US have the highest number of nanotechnology publications, China and other Asian countries are increasing their publications rapidly, taking an ever-larger proportion of the total. When viewed in terms of the quality-based measure of citations, Asian nanotechnology researchers also show growth in recent years. However, by such citation measures, the US still maintains a strongly dominant position, followed by the EU.

Analyzing Data Citations to Assess the Scientific and Societal Value of Scientific Data

Stakeholders in the creation, distribution, support, funding, and use of scientific data can benefit by understanding the value that the data have for society and science. For decades, the scientific community has been using citations of articles in the published scientific literature as one of the primary measures used for evaluating the performance of scientists, departments, institutions, and scientific disciplines. Similarly, citations in the published literature of scientific data may be useful for measuring and assessing the value of the scientific data and the performance of the individuals, projects, programs, and organizations that have contributed to the data and their use. The results of citation analysis and other assessments of the value of data also can contribute to planning for future data collection, development, distribution, and preservation efforts. The planned release of new data citation indexes and the more widespread adoption of unique data identifiers and automated attribution mechanisms have the potential to improve significantly the capabilities for analyzing citations of scientific data. In addition, rapid developments in the systems and capabilities for disseminating data, along with education and workforce development on the importance of data attribution and on techniques for data citation, can improve practices for citing scientific data. Such practices need to lead not only to better aggregate statistics about data citation, but also to improved characterization and understanding of the impact of data use in terms of the benefits for science and society. Analyses of citations in the scientific literature were conducted for data that were distributed by an interdisciplinary scientific data center during a five-year period (1997 - 2011), to identify the scientific fields represented by the journals and books in which the data were cited. Secondary citation analysis also was conducted for a sample of scientific publications that used

Journal ranking based on the impact factor (IF) can be distorted by self-citation. The aim of this study is to investigate the present status of self-citation in the plastic surgery journals and its effect on the journals' IFs. IF, IF without self-citations (corrected IF), self-cited rate, and self-citing rate for 11 plastic surgery journals were investigated from 2009-2015, by reviewing the Journal Citation Report ® . The correlations of the IF with the self-cited rate and the self-citing rate were statistically assessed. In addition, Plastic and Reconstructive Surgery was compared with 15 top journals from other surgical specialties in 2015. IF was significantly correlated with the self-cited rate (R: 0.594, p = 0.001) and the self-citing rate (R: 0.824, p citation rate positively affects the IF in plastic surgery journals. A high concentration of self-citation of some journals could distort the ranking among plastic surgery journals in general.

Self-citation rates among medical imaging journals and a possible association with impact factor

International Nuclear Information System (INIS)

Kurmis, Timothy P.; Kurmis, Andrew P.

2010-01-01

Purpose: Since conceptualisation in 1955, journal impact factors (IFs) have evolved as surrogate markers of perceived 'quality'. However, no previous research has explored the relationship between IF and journal self-citation rate, which may inflate this measure. Given Radiography's ongoing push to achieve Medline and ISI database inclusion, this paper aimed to quantitatively explore the frequency of self-citation and correlate this with ISI-reported IF. Methods: A review of articles published in two peer-reviewed, Medline and ISI-listed, imaging journals (Radiology and Academic Radiology), and Radiography, within in a 12-month period, was performed. The total number of citations and self-citations per article was recorded, and the results compared. Basic statistical and correlation analyses between listed IF ratings and self-citation indices were also performed. Results and Discussion: To our knowledge, this work represents the preliminary investigation exploring the association between ISI-listed IF and self-citation frequency. From the current results it can be suggested that such a relationship does exist, as demonstrated by the strongly positive correlation statistic (Pearson's r 2 = 0.99). Radiology was noted to have a considerably larger mean number of self-citations per article than the other two journals (p < 0.01), despite near-equivalent numbers of references per article. Conclusion: Our findings suggest that there may be relationship between an ISI-listed IFs and journal self-citation rates. It is hoped that this paper will be of interest in academic and research circles, both within medical imaging and more widely, and may provide impetus for discussion relating to self-citation frequency and influence on resultant IF calculations.

[The medical dissertation--no definitive model. Results of a survey about obtaining a doctorate contradict frequently stated opinions].

Weihrauch, M; Strate, J; Pabst, R

The relevance of medical dissertations is controversial in Germany. The "Wissenschaftsrat" (Science Council) of Germany even made the radical proposal of abolishing medical dissertations, in their present form, in the recently published "Guidelines on writing a thesis". Using a questionnaire with 22 items all students submitting their dissertations within one year at the Medical School in Hannover were asked to participate in a survey about the dissertation, supervision, time spent on it and publishing the results. The answers were evaluated statistically by explorative data analysis. A total of 232 questionnaires were evaluated, which is equivalent to a response rate of 87% (47% were women). A majority of 69% had prepared their thesis in a clinical institution. The supervision during various phases of the dissertation was graded as good. Altogether 90% thought that it had been personally worth-while. In 57% of cases the data of the dissertation had already been published and in 39 % of these cases the author of the dissertation was listed as first author of the publication. In agreement with former studies in German universities an overwhelming majority of 90% of respondents graded dissertations as a significant part of their medical studies, although requiring much additional time. They would recommend such a research phase to younger students as highly valuable. These results are in contrast to many repeatedly made statements.

The objective of this study was to identify the 100 most cited, peer-reviewed burn-related articles over the past half century. Burn care presents ongoing challenges to both U.S. civilian and military healthcare personnel. Improvements in burn survival and quality of life are the result of advances in burn research. The Web of Science (including Science Citation Index) was searched for the most cited articles related to burn care, published from 1955 to the present. The most cited article was "Permanent coverage of large burn wounds with autologous cultured human epithelium," by G.G. Gallico et al, New England Journal of Medicine, 1984 (711 citations). Between the 1970s and the 1990s, there was a near doubling of the number of highly cited publications with each subsequent decade. A total of 85% of the articles were on the topics of pathophysiology (37%), wounds, tissue, or dressings (31%), or organ failure/sepsis (17%). B.A. Pruitt Jr. (2320 citations), D.N. Herndon (1972 citations), and A.D. Mason Jr. (1435 citations) were the most cited authors. This study identified some of the most important contributions to burn research and the areas of greatest scientific interest to the specialty during the past five decades, and highlights key research that has contributed to the evolution of modern burn care.

CITATION-LDI2, 2-D Multigroup Diffusion, Perturbation, Criticality Search, for PC

International Nuclear Information System (INIS)

2001-01-01

1 - Description of program or function: CITATION is designed to solve problems using the finite difference representation of neutron diffusion theory, treating up to three space dimensions with arbitrary group to group scattering. X-y-z, theta-r-z, hexagonal z, and trigonal z geometries may be treated. Depletion problems may be solved and fuel managed for multi-cycle analysis. Extensive first order perturbation results may be obtained given microscopic data and nuclide concentrations. Statics problems may be solved and perturbation results obtained with microscopic data. This version of CITATION was released by ORNL as CITATION - Rev. 2, Supplement 3 in July 1972 and ran on mainframes. It was first ported to PC by AECL in October 1988. CITATION-PC included in the March 1996 package involved minor changes including the removal of overlay statements introduced in 1988. CITALDI-PC is a new modified version with list-directed input. The codes in this package accept cross sections in CITATION format. Macroscopic data may be entered according to format specifications in Section 008 of the published report. Microscopic data format is specified in Section 105. There are no codes in RSIC's code collection to generate data in CITATION format. 2 - Method of solution: Explicit, finite difference approximations in space and time have been implemented. The neutron-flux-eigenvalue problems are solved by direct iteration to determine the multiplication factor or the nuclide densities required for a critical system

Colil: a database and search service for citation contexts in the life sciences domain.

To promote research activities in a particular research area, it is important to efficiently identify current research trends, advances, and issues in that area. Although review papers in the research area can suffice for this purpose in general, researchers are not necessarily able to obtain these papers from research aspects of their interests at the time they are required. Therefore, the utilization of the citation contexts of papers in a research area has been considered as another approach. However, there are few search services to retrieve citation contexts in the life sciences domain; furthermore, efficiently obtaining citation contexts is becoming difficult due to the large volume and rapid growth of life sciences papers. Here, we introduce the Colil (Comments on Literature in Literature) database to store citation contexts in the life sciences domain. By using the Resource Description Framework (RDF) and a newly compiled vocabulary, we built the Colil database and made it available through the SPARQL endpoint. In addition, we developed a web-based search service called Colil that searches for a cited paper in the Colil database and then returns a list of citation contexts for it along with papers relevant to it based on co-citations. The citation contexts in the Colil database were extracted from full-text papers of the PubMed Central Open Access Subset (PMC-OAS), which includes 545,147 papers indexed in PubMed. These papers are distributed across 3,171 journals and cite 5,136,741 unique papers that correspond to approximately 25 % of total PubMed entries. By utilizing Colil, researchers can easily refer to a set of citation contexts and relevant papers based on co-citations for a target paper. Colil helps researchers to comprehend life sciences papers in a research area more efficiently and makes their biological research more efficient.

Data Citation Policies of Data Providers within the scope of Longitudinal Studies in Life Course Research

Energy Technology Data Exchange (ETDEWEB)

Reinhold, A.; Rittberger, M.; Mahrholz, N.

2016-07-01

In this article, a small-scale case study analyzing the nature of data citation policies within the scope of longitudinal studies in life course research is presented. The sample consists of eight data providers from Europe, North-America and Australia and was evaluated with regard to eight criteria which potentially affect data citation behavior of researchers in the field, for example the wording of data citation obligations or sanctions for not citing research data in accordance to given requirements. The study demonstrates that research data providers follow a wide range of approaches to data citation, especially in terms of data citation location within a publication as well as disposal obligations for data-related publications. However, this diversity might lead to inconsistency in data citation behaviour and also to a general lack of comparability of data citation quantity and quality as relevant factors in research evaluation.

Specialized and emerging fields of research infrequently cross disciplinary boundaries and would benefit from frameworks, methods, and materials informed by other fields. Document co-citation analysis, a method developed by bibliometric research, is demonstrated as a way to help identify key literature for cross-disciplinary ideas. To illustrate the method in a useful context, we mapped peer-recognized scholarship related to systems thinking. In addition, three procedures for validation of co-citation networks are proposed and implemented. This method may be useful for strategically selecting information that can build consilience about ideas and constructs that are relevant across a range of disciplines. PMID:29308433
