    markdownabstract__Abstract__ The premise underlying the use of citations data is that higher quality journals generally have a higher number of citations. The impact of citations can be distorted in a number of ways. Journals can, and do, inflate the number of citations through self citation practices, which may be coercive. Another method for distorting journal impact is through a set of journals agreeing to cite each other, that is, by exchanging citations. This may be less coercive than se...

    Cited author searches were conducted in Nursing Citation Index to determine its utility in locating clinical studies that apply the conceptual frameworks of Dorothea Orem, Callista Roy, Martha Rogers, Betty Neuman, and Dorothy Johnson. Fully 75 percent of the relevant papers would have been missed by a conventional subject/textword search in the MEDLINE or CINAHL databases. Had Nursing Citation Index not been available, only 22 percent of relevant papers could have been retrieved by cited author searches of Social Science Citation Index. In summary, Nursing Citation Index provides an important indexing link between nursing theory and nursing research. PMID:2655783

    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....... 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...... 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....

    This is a report about the use and misuse of citation data in the assessment of scientific research. The idea that research assessment must be done using ``simple and objective'' methods is increasingly prevalent today. The ``simple and objective'' methods are broadly interpreted as bibliometrics, that is, citation data and the statistics derived from them. There is a belief that citation statistics are inherently more accurate because they substitute simple numbers for complex judgments, and...

    This study analyses determinants of citation success among authors publishing in economic history journals. Bibliometric features, like article length and number of authors, are positively correlated with the citation rate up to a certain point. Remarkably, publishing in top-ranked journals hardly...... affects citations. In regard to author-specific characteristics, male authors, full professors and authors working economics or history departments, and authors employed in Anglo-Saxon countries, are more likely to get cited than others. As a ‘shortcut' to citation success, we find that research diffusion...

  14. Mainstream rapid thermal processing for source-drain engineering from first applications to latest results

    International Nuclear Information System (INIS)

    Rapid thermal processing (RTP) technology has been commercially available in the semiconductor industry for about 30 years. Already in 1957, e.g., a solar furnace with a parabolic Al reflector was designed. Despite this, it took several decades for RTP of semiconductors to penetrate the market. Over the last decade, RTP has become a mature application. As a replacement of standard furnaces, it provides outstanding ambient control and very short heating cycles with the highest ramp rates for promotion of desired processes such as implant activation, silicide formation or oxide growth while suppressing unintended processes like diffusion or surface degradation. In the field of ultra-shallow junction (USJ) formation, which is necessary to avoid short channel effects arising during continued scaling of CMOS devices, RTP is indispensable. With the introduction of CoSi2 as the source-drain contact material and its transition to NiSi for future technology nodes, RTP delivers unique benefits in terms of ambient control and single wafer processing capability. In the current paper, we will present the development and potential of RTP throughout this era and show latest results in USJ annealing as well as source-drain contact formation down to the 90 and 65 nm technology node of the ITRS2003, respectively

    Full Text Available 無Citation analysis has been an important area of informetrics (or bibliometrics for severai decades. It mainly deals with the study of the relationship between citing and cited documents. A number of studies have been done to explore citation analysis and its applications. These studies have different opinions about the nature and the complexities of the citing process. Theories of citation have been debated for decades and can never be complete. By reviewing many empirical studies, this article describes the development and critique of citation analysis. especially focuses on the citation classifications, citation functions, citation concepts and citation motivations.

  16. Aberration of the Citation.

    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. PMID:26636372

    2014-06-01

    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

    2012-07-01

    Assessing forest cover of Sri Lanka is becoming important to lower the pressure on forest lands as well as man-elephant conflicts. Furthermore, the land access to north-east Sri Lanka after the end of 30 years long civil war has increased the need of regularly updated land cover information for proper planning. This study produced an assessment of the forest cover of Sri Lanka using two satellite data based maps within 23 years of time span. For the old forest cover map, the study used one of the first island-wide digital land cover classification produced by the main author in 1988. The old land cover classification was produced at 80 m spatial resolution, using Landsat MSS data. A previously published another study by the author has investigated the application feasibility of MODIS and Landsat MSS imagery for a selected sub-section of Sri Lanka to identify the forest cover changes. Through the light of these two studies, the assessment was conducted to investigate the application possibility of MODIS 250 m over a small island like Sri Lanka. The relation between the definition of forest in the study and spatial resolution of the used satellite data sets were considered since the 2012 map was based on MODIS data. The forest cover map of 1988 was interpolated into 250 m spatial resolution to integrate with the GIS data base. The results demonstrated the advantages as well as disadvantages of MODIS data in a study at this scale. The successful monitoring of forest is largely depending on the possibility to update the field conditions at regular basis. Freely available MODIS data provides a very valuable set of information of relatively large green patches on the ground at relatively real-time basis. Based on the changes of forest cover from 1988 to 2012, the study recommends the use of MODIS data as a resalable method to forest assessment and to identify hotspots to be re-investigated. It's noteworthy to mention the possibility of uncounted small isolated pockets of

  3. Time and Citation Networks

    Clough, James R

    2015-01-01

    Citation networks emerge from a number of different social systems, such as academia (from published papers), business (through patents) and law (through legal judgements). A citation represents a transfer of information, and so studying the structure of the citation network will help us understand how knowledge is passed on. What distinguishes citation networks from other networks is time; documents can only cite older documents. We propose that existing network measures do not take account of the strong constraint imposed by time. We will illustrate our approach with two types of causally aware analysis. We apply our methods to the citation networks formed by academic papers on the arXiv, to US patents and to US Supreme Court judgements. We show that our tools can reveal that citation networks which appear to have very similar structure by standard network measures turn out to have significantly different properties. We interpret our results as indicating that many papers in a bibliography were not directly...

    2010-06-01

    Full Text Available Abstract CiTO, the Citation Typing Ontology, is an ontology for describing the nature of reference citations in scientific research articles and other scholarly works, both to other such publications and also to Web information resources, and for publishing these descriptions on the Semantic Web. Citation are described in terms of the factual and rhetorical relationships between citing publication and cited publication, the in-text and global citation frequencies of each cited work, and the nature of the cited work itself, including its publication and peer review status. This paper describes CiTO and illustrates its usefulness both for the annotation of bibliographic reference lists and for the visualization of citation networks. The latest version of CiTO, which this paper describes, is CiTO Version 1.6, published on 19 March 2010. CiTO is written in the Web Ontology Language OWL, uses the namespace http://purl.org/net/cito/, and is available from http://purl.org/net/cito/. This site uses content negotiation to deliver to the user an OWLDoc Web version of the ontology if accessed via a Web browser, or the OWL ontology itself if accessed from an ontology management tool such as Protégé 4 (http://protege.stanford.edu/. Collaborative work is currently under way to harmonize CiTO with other ontologies describing bibliographies and the rhetorical structure of scientific discourse.

    Serbia is a country with relatively small scale terrain features with economy mostly based on local landowners' agricultural production. Climate change analysis must be downscaled accordingly, to recognize climatological features of the farmlands. Climate model simulations and impact studies significantly contribute to the future strategic planning in economic development and therefore impact analysis must be approached with high level of confidence. This paper includes research related to climate change and impacts in Serbia resulted from cooperative work of the modeling and user community. Dynamical downscaling of climate projections for the 21st century with multi-model approach and statistical bias correction are done in order to prepare model results for impact studies. Presented results are from simulations performed using regional EBU-POM model, which is forced with A1B and A2 SRES/IPCC (2007) with comparative analysis with other regional models and from the latest high resolution NMMB simulations forced with RCP8.5 IPCC scenario (2012). Application of bias correction of the model results is necessary when calculated indices are not linearly dependent on the model results and delta approach in presenting results with respect to present climate simulations is insufficient. This is most important during the summer over the north part of the country where model bias produce much higher temperatures and less precipitation, which is known as "summer drying problem" and is common in regional models' simulations over the Pannonian valley. Some of the results, which are already observed in present climate, like higher temperatures and disturbance in the precipitation pattern, lead to present and future advancement of the start of the vegetation period toward earlier dates, associated with an increased risk of the late spring frost, extended vegetation period, disturbed preparation for the rest period, increased duration and frequency of the draught periods, etc

    In this paper, we study the citation decision of a scientific author. By citing a related work, authors can make their arguments more persuasive. We call this the correlation effect. But if authors cite other work, they may give the impression that they think the cited work is more competent than theirs. We call this the reputation effect. These two effects may be the main sources of citation bias. We empirically show that there is a citation bias in Economics by using data from RePEc. We als...

    Satellite-gauge quantitative precipitation estimate (QPE) products may reduce the errors in near real-time satellite precipitation estimates by combining rain gauge data, which provides great potential to hydrometeorological applications. This study aims to comprehensively evaluate four of the latest satellite-gauge QPEs, including NASA's Tropical Rainfall Measuring Mission (TRMM) 3B42V7 product, NOAA's Climate Prediction Center (CPC) MORPHing technique (CMORPH) bias-corrected product (CMORPH CRT), CMORPH satellite-gauge merged product (CMORPH BLD) and CMORPH satellite-gauge merged product developed at the National Meteorological Information Center (NMIC) of the China Meteorological Administration (CMA) (CMORPH CMA). These four satellite-gauge QPEs are statistically evaluated over the Huaihe River basin during 2003-2012 and applied into the distributed Variable Infiltration Capacity (VIC) model to assess hydrologic utilities. Compared to the China Gauge-based Daily Precipitation Analysis (CGDPA) newly developed at CMA/NMIC, the four satellite-gauge QPEs generally depict the spatial distribution well, with the underestimation in the southern mountains and overestimation in the northern plain of the Huaihe River basin. Specifically, both TRMM and CMORPH CRT adopt simple gauge adjustment algorithms and exhibit relatively poor performance, with evidently deteriorated quality in winter. In contrast, the probability density function-optimal interpolation (PDF-OI) gauge adjustment procedure has been applied in CMORPH BLD and CMORPH CMA, resulting in higher quality and more stable performance. CMORPH CMA further benefits from a merged dense gauge observation network and outperforms the other QPEs with significant improvements in rainfall amount and spatial/temporal distributions. Due to the insufficient gauge observations in the merging process, CMORPH BLD features the similar error characteristics of CMORPH CRT with a positive bias of light precipitation and a negative

    Goldberg, S R; Evans, T S

    2014-01-01

    The distribution of the number of academic publications as a function of citation count for a given year is remarkably similar from year to year. We measure this similarity as a width of the distribution and find it to be approximately constant from year to year. We show that simple citation models fail to capture this behaviour. We then provide a simple three parameter citation network model using a mixture of local and global search processes which can reproduce the correct distribution over time. We use the citation network of papers from the hep-th section of arXiv to test our model. For this data, around 20% of citations use global information to reference recently published papers, while the remaining 80% are found using local searches. We note that this is consistent with other studies though our motivation is very different from previous work. Finally, we also find that the fluctuations in the size of an academic publication's bibliography is important for the model. This is not addressed in most mode...

  4. PRAGMATIC ASPECT OF CITATION

    Directory of Open Access Journals (Sweden)

    Tatiana Sergeevna SIRENKO

    2015-02-01

    Full Text Available The article is devoted to the research of the prag-matic aspect of citation in fictional text from the in-tertextual point of view. The theory of intertextuality was formed in the works of M.Bakhtin and devel-oped by Y. Kristeva after the analysis of the works of post-modern writers. So allusion and citation began to be investigated not from the philology point of view only but from the linguistics as well. The pur-pose of the article is to investigate the pragmatic aspect of citation which includes also the investiga-tion of its pragmatic functions. Different views on the citation classification are also mentioned in the article as it is an actual problem in modern linguis-tics. Novels by British writer J. Fforde are the mate-rial for the investigation article because they pos-sess a big amount of intertextual inclusion in the text in general and citation in particular.

  5. Scientific citations in Wikipedia

    CERN Document Server

    Nielsen, Finn Aarup

    2007-01-01

    The Internet-based encyclopaedia Wikipedia has grown to become one of the most visited web-sites on the Internet. However, critics have questioned the quality of entries, and an empirical study has shown Wikipedia to contain errors in a 2005 sample of science entries. Biased coverage and lack of sources are among the "Wikipedia risks". The present work describes a simple assessment of these aspects by examining the outbound links from Wikipedia articles to articles in scientific journals with a comparison against journal statistics from Journal Citation Reports such as impact factors. The results show an increasing use of structured citation markup and good agreement with the citation pattern seen in the scientific literature though with a slight tendency to cite articles in high-impact journals such as Nature and Science. These results increase confidence in Wikipedia as an good information organizer for science in general.

    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.

    Full Text Available The Lemon8-XML software application, developed by the Public Knowledge Project (PKP, provides an open-source, computer-assisted interface for reliable citation structuring and validation. Lemon8-XML combines citation parsing algorithms with freely-available online indexes such as PubMed, WorldCat, and OAIster. Fully-automated markup of entire bibliographies may be a genuine possibility using this approach. Automated markup of citations would increase bibliographic accuracy while reducing copyediting demands.

  11. Application of health effect model of NUREG/CR-4214 to the Japanese population and comparison with a latest model

    International Nuclear Information System (INIS)

    Radiation-induced cancer is one of the key issues in a consequence analysis on a Nuclear Power Plant accident. U. S. Nuclear Regulatory Commission (USNRC) developed the estimation model of those risks for the use of accident consequence analysis in 1980s and 1990s. This model is still used as a leading model in this field. In this paper, we aimed to explore the differences between the results of risk prediction from the model of USNRC and those from a latest model. To achieve this aim, radiation-induced cancer risks were projected based on the Japanese population statistics using the models developed by USNRC and the latest model, which was developed by U. S. Environmental Protection Agency (USEPA). As compared to the model of USEPA, the lifetime attributable risks of all cancers projected by the model of USNRC were about 30% higher for male and about 35% lower for female in both morbidity and mortality. When the sex-averaged values were compared between them, the difference is within 10%. (author)

    2011-01-01

    Radicchi, Fortunato, and Castellano [arXiv:0806.0974, PNAS 105(45), 17268] claim that, apart from a scaling factor, all fields of science are characterized by the same citation distribution. We present a large-scale validation study of this universality-of-citation-distributions claim. Our analysis shows that claiming citation distributions to be universal for all fields of science is not warranted. Although many fields indeed seem to have fairly similar citation distributions, there are quite some exceptions as well. We also briefly discuss the consequences of our findings for the measurement of scientific impact using citation-based bibliometric indicators.

    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...

  1. Latest generation flotation in applications with industrial waste waters; Flotacion de ultima generacion en aplicaciones con aguas industriales

    Energy Technology Data Exchange (ETDEWEB)

    Galdi, M.; Azzollini, G.

    2004-07-01

    The article provides an introduction to the historical development of water flotation equipment. Its earliest application was in paper-making factories where it was used to recover cellulose fibres. As it was improved, it was employed to treat waste waters with hydraulic loads of 4,8 m''3/m''2+h. Further improvements gave it a circular shape with the flocculation in the middle and a highly controlled radial flow and the speed increased to 5.4 m''3/m''2*/h. Recently, Ecomac, a flotation system whose performance is close to the ideal. has been developed. In this system the fluid is immobile, as the advanced design of the internal conduits eliminates turbulence by distributing the liquid right across the annular section of the tank and feeds compartments of decreasing cross sections. This arrangement allows it to cope with hydraulic loads of 8.4 m''3/m''2*h. Practical performance results obtained in the mechanical,food (yoghurt, preserves, wine) and textile dyeing industries are given. (Author)

    In this article on the effect of physical activity on depression, data have been drawn from several meta-analyses, in particular, the latest Cochrane review entitled »Exercise for depression« published in 2013. The results show that physical activity can help prevent the onset and relapse of depression. Depressed people should be recommended aerobic or muscular strength training. There is clear evidence that physical activity alone is beneficial for the treatment of mild and moderate depression and can reduce symptoms of mild to moderate depression to the same extent as standard treatments (psychotherapy and antidepressant medication). Combining physical activity with these treatments may yield additional benefits. Individuals with depression should be recommended physical activity in adjunct to psychotherapy and medication.

Simple mathematical probability, not genius, can explain why some papers are cited a lot more than the other.

    We argue that citation is a composed indicator: short-term citations can be considered as currency at the research front, whereas long-term citations can contribute to the codification of knowledge claims into concept symbols. Knowledge claims at the research front are more likely to be transitory and are therefore problematic as indicators of quality. Citation impact studies focus on short-term citation, and therefore tend to measure not epistemic quality, but involvement in current discours...

  11. Relative Citation Ratio (RCR): A New Metric That Uses Citation Rates to Measure Influence at the Article Level.

    Hutchins, B Ian; Yuan, Xin; Anderson, James M; Santangelo, George M

    2016-09-01

    Despite their recognized limitations, bibliometric assessments of scientific productivity have been widely adopted. 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. A beta version of iCite, our web tool for calculating Relative Citation Ratios of articles listed in PubMed, is available at https://icite.od.nih.gov. PMID:27599104

  12. Visualization of the Citation Impact Environments of Scientific Journals: An online mapping exercise

    CERN Document Server

    2009-01-01

    Aggregated journal-journal citation networks based on the Journal Citation Reports 2004 of the Science Citation Index (5968 journals) and the Social Science Citation Index (1712 journals) are made accessible from the perspective of any of these journals. The user is thus able to analyze the citation environment in terms of links and graphs. Furthermore, the local impact of a journal is defined as its share of the total citations in the specific journal's citation environments; the vertical size of the nodes is varied proportionally to this citation impact. The horizontal size of each node can be used to provide the same information after correction for within-journal (self)-citations. In the "citing" environment, the equivalents of this measure can be considered as a citation activity index which maps how the relevant journal environment is perceived by the collective of authors of a given journal. As a policy application, the mechanism of interdisciplinary developments among the sciences is elaborated for th...

    2016-05-01

    I report the latest results from the Double Chooz experiment on the θ13 neutrino mixing angle. Two detectors are located at distances of 400 m and 1050 m from the reactor cores of the Chooz nuclear power station (France) to measure the disappearance of electron antineutrinos. The far detector has been taking data since 2011, accumulating a live time of 467.90 days (66.5 GW-ton-year). In this article we focus on the latest measurement using neutrino-induced neutron capture on hydrogen. A new analysis improved the signal efficiency and reduced the backgrounds and systematic uncertainties, leading to sin2 2θ 13 = 0.095+0.039 -0.038. When combined with the Gadolinium-based analysis this leads to sin2 2θ13 = 0.088+0.33 -0.033. The distortion from the prediction above a visible energy of 4 MeV is confirmed. The near detector started data taking in 2014 and first results shall be reported in 2016.

  4. 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...

    By adopting a citation-based recursive ranking method for patents the evolution of new fields of technology can be traced. Specifically, it is demonstrated that the laser / inkjet printer technology emerged from the recombination of two existing technologies: sequential printing and static image production. The dynamics of the citations coming from the different "precursor" classes illuminates the mechanism of the emergence of new fields and give the possibility to make predictions about future technological development. For the patent network the optimal value of the PageRank damping factor is close to 0.5; the application of d=0.85 leads to unacceptable ranking results.

    2013-12-01

    Data citations are growing in visibility in scientific and public policy circles. Data citations directly link scholarship and data, and as such provide a mechanism through which data can be discovered and accessed, scholarly use of data can be tracked, and the impact of data facilities can be identified. The interest in data citations is coming from many research stakeholders, including funders, policy makers, professional societies and their publication entities, research organizations, and individual researchers. Most of the efforts to date around data citations have focused on the challenges of assigning unique identifiers to digital data sets. While these challenges are significant, an additional challenge has gone relatively unaddressed, namely, the fact that data citation is not a common practice within scientific communities. This presentation will present findings from an interview study within the University Corporation for Atmospheric Research / National Center for Atmospheric Research (UCAR/NCAR). Through interviews with 14 scientists and engineers, we have found that there is little evidence that data citations have gained momentum as a common practice. Currently, data users acknowledge their use of particular data sets in either the research methods or acknowledgements sections of their papers, not as formal citations in a paper's bibliography. Data users are often 1) unaware that they can and should cite data sets, 2) unsure of how to cite data sets, and 3) lacking career motivations to forward data citations as a common activity. Data citation initiatives will have minimal impact on the scientific community if they do not address this practical inertia. Data users are a critical stakeholder in the data citation process. Their voice needs to be central to the data citation discussion. We will discuss how outreach efforts need to focus on raising the profile of data citations by informing scientists and administrators, being proactive in providing

  8. Double Chooz: Latest results

    CERN Document Server

    Crespo-Anadón, J I

    2014-01-01

    The latest results from the Double Chooz experiment on the neutrino mixing angle $\\theta_{13}$ are presented. A detector located at an average distance of 1050 m from the two reactor cores of the Chooz nuclear power plant has accumulated a live time of 467.90 days, corresponding to an exposure of 66.5 GW-ton-year (reactor power $\\times$ detector mass $\\times$ live time). A revised analysis has boosted the signal efficiency and reduced the backgrounds and systematic uncertainties compared to previous publications, paving the way for the two detector phase. The measured $\\sin^2 2\\theta_{13} = 0.090^{+0.032}_{-0.029}$ is extracted from a fit to the energy spectrum. A deviation from the prediction above a visible energy of 4 MeV is found, being consistent with an unaccounted reactor flux effect, which does not affect the $\\theta_{13}$ result. A consistent value of $\\theta_{13}$ is measured in a rate-only fit to the number of observed candidates as a function of the reactor power, confirming the robustness of the ...

    Full Text Available World consumers are looking for personal care products that supply multiple benefits with minimal efforts. They also expect the latest technology advances to be incorporated into innovative formulations. The trend toward therapeutic cosmetics will lead to a better understanding of modern ingredients and their assessment techniques. To obtain skin care formulations with real consumer-perceivable benefits and to optimize sensory attributes, formulators are resorting to technology that until recently was exclusively used in cosmetic products. Various formulations comes under special delivery systems like Vesicular, Particulate systems, emulsions type Particulate type and other delivery systems along with their applications are shown in this article, as it results in an economic uplift of cosmetic industry in various parts of the world. Little evidence is seen that nanoparticles in cosmetics and sunscreen might be a problem at this time and its need is further explored for a better understanding of these novel technologies. Thus, novel cosmaceutical delivery systems reviewed here possess enormous potential as next-generation smarter carrier systems.

  10. Latest design of gate valves

    Energy Technology Data Exchange (ETDEWEB)

    Kurzhofer, U.; Stolte, J.; Weyand, M.

    1996-12-01

    Babcock Sempell, one of the most important valve manufacturers in Europe, has delivered valves for the nuclear power industry since the beginning of the peaceful application of nuclear power in the 1960s. The latest innovation by Babcock Sempell is a gate valve that meets all recent technical requirements of the nuclear power technology. At the moment in the United States, Germany, Sweden, and many other countries, motor-operated gate and globe valves are judged very critically. Besides the absolute control of the so-called {open_quotes}trip failure,{close_quotes} the integrity of all valve parts submitted to operational forces must be maintained. In case of failure of the limit and torque switches, all valve designs have been tested with respect to the quality of guidance of the gate. The guidances (i.e., guides) shall avoid a tilting of the gate during the closing procedure. The gate valve newly designed by Babcock Sempell fulfills all these characteristic criteria. In addition, the valve has cobalt-free seat hardfacing, the suitability of which has been proven by friction tests as well as full-scale blowdown tests at the GAP of Siemens in Karlstein, West Germany. Babcock Sempell was to deliver more than 30 gate valves of this type for 5 Swedish nuclear power stations by autumn 1995. In the presentation, the author will report on the testing performed, qualifications, and sizing criteria which led to the new technical design.

  11. Measuring contextual citation impact of scientific journals

    CERN Document Server

    Moed, Henk F

    2009-01-01

    This paper explores a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal's contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field's literature. It further develops Eugene Garfield's notions of a field's 'citation potential' defined as the average length of references lists in a field and determining the probability of being cited, and the need in fair performance assessments to correct for differences between subject fields. A journal's subject field is defined as the set of papers citing that journal. SNIP is defined as the ratio of the journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields....

    2016-08-01

    Self-references, self-citations are considered by some as the sign of vanity, and deemed to be omitted from scientometrics analyses. In fact, self-citations reveal information in the study of scientific communications that is different but not less valuable than citations received from others. In the practice of self-citation severe ethical issues may emerge that can be bandled by the co-operation of the authors, editors and publishers. Orv. Hetil., 2016, 157(32), 1289-1293. PMID:27499288

  1. Evaluation of Content Pertinence through Citation Count

    Directory of Open Access Journals (Sweden)

    Adeleke Victor Adedayo

    2016-06-01

    Full Text Available In one of the online publications of Nature Publishing Group, Ball discussed issues relating to negative citation of science publications.[1] He identified from the work of Alexander Oettl, an economist, at the Georgia Institute of Technology in Atlanta that the rate at which negative citations appear in the literature is low but not negligible. In the work of Alexander Oettl, the study team checked through citations in articles published in the Journal of Immunology. Immunologists helped the team to manually classifying “negative” citations. Overall, it was found that only about 2.4% of the citations were “negative.” Although the paper concluded that the rate of the negative citation was low but not negligible, one may be tempted to conclude that the problem with citations analytics is a minor one. Unfortunately, this may not be the real situation because the significant amount of critiques on citation analytics indicates that the problem is not minor. Read more. . .

  3. Citation score normalized by cited references (CSNCR): The introduction of a new citation impact indicator

    CERN Document Server

    Bornmann, Lutz

    2016-01-01

    In this paper, a new field-normalized indicator is introduced, which is rooted in early insights in bibliometrics, and is compared with several established field-normalized indicators (e.g. the mean normalized citation score, MNCS, and indicators based on percentile approaches). Garfield (1979) emphasizes that bare citation counts from different fields cannot be compared for evaluative purposes, because the "citation potential" can vary significantly between the fields. Garfield (1979) suggests that "the most accurate measure of citation potential is the average number of references per paper published in a given field". Based on this suggestion, the new indicator is basically defined as follows: the citation count of a focal paper is divided by the mean number of cited references in a field to normalize citations. The new indicator is called citation score normalized by cited references (CSNCR). The theoretical analysis of the CSNCR shows that it has the properties of consistency and homogeneous normalizatio...

  4. The latest sorbent testing

    International Nuclear Information System (INIS)

    This paper describes an efficient oil spill and chemical hazards response equipment testing program. The type of equipment tested include sorbents, skimmers, pumps, oil-water separators and other mechanical containment and recovery products, with the emphasis on sorbents. The ultimate goal of the testing program developed by Science Applications International Corporation (SAIC Canada) of North York and Ottawa, Ontario, is to develop databases of performance information regarding oil spill equipment which would be tested to internationally recognized standards such as those developed by ASTM for oil spill recovery equipment. To date, a range of performance and handling criteria have been identified which enable end users to determine their priorities and rank sorbents accordingly. A recent successful application of the testing system involved the test of recovery devices designed to deal with some peculiar properties of a heavy oil (extreme viscosity and stickiness), properties which make conventional spill response equipment and techniques ineffective. A more extensive description of the system is promised at the Environment Canada-sponsored Arctic and Marine Oil Spill Technical Seminar scheduled for June in Vancouver

    Directory of Open Access Journals (Sweden)

    V. Dilip Kumar, B. Saraswathi and N. Prudvi Kanth

    2013-11-01

    Full Text Available Poor patient compliance is a frequent problem in daily clinical practice. The unfavorable pharmacokinetic of the drug, the inconveniences of the standard form of such drug application and the side effects due to the administration route often are the reasons for this. The high and self-optimizing deformability of typical composite transferosomes membrane, which are adaptable to ambient tress allow the ultra-deformable transferosomes to change its membrane composition locally and reversibly, when it is pressed against or attracted into narrow pore. Transferosomes possess an infrastructure consisting of hydrophobic and hydrophilic moieties together and as a result can accommodate drug molecules with wide range of solubility. Transferosomes can deform and pass through narrow constriction (from 5 to 10 times less than their own diameter without measurable loss. This high deformability gives better penetration of intact vesicles. They can act as a carrier for low as well as high molecular weight drugs e.g. analgesic, anesthetic, corticosteroids, sex hormone, anticancer, insulin, gap junction protein, and albumin.

    Oosterloo, Tom; van Cappellen, Wim; (,; Astronomy, Netherlands Institute or Radio; Dwingeloo,; Institute, Kapteyn Astronomical; Groningen,

    2010-01-01

    We describe a Phased Array Feed (PAF) system, called Apertif, which will be installed in the Westerbork Synthesis Radio Telescope (WSRT). The aim of Apertif is, at frequencies from 1.0 to 1.7 GHz, to increase the instantaneous field of view of the WSRT 8 deg^2 and its observing bandwidth to 300 MHz with high spectral resolution. This system will turn the WSRT into an effective survey telescope with scientific applications ranging from deep surveys of the northern sky of HI and OH emission and polarised continuum to efficient searches for pulsars and transients. We present results obtained with a prototype PAF installed in one of the WSRT dishes. These results demonstrate that at decimetre wavelengths PAFs have excellent performance and that even for a single beam on the sky they outperform single feed radio dishes. PAFs turn radio telescopes into very effective survey instruments. Apertif is now fully funded and the community is invited to express their interest in using Apertif (http://www.astron.nl/radio-ob...

  13. Inheritance Patterns in Citation Networks Reveal Scientific Memes

    Science.gov (United States)

    Kuhn, Tobias; Perc, Matjaž; Helbing, Dirk

    2014-10-01

    Memes are the cultural equivalent of genes that spread across human culture by means of imitation. What makes a meme and what distinguishes it from other forms of information, however, is still poorly understood. Our analysis of memes in the scientific literature reveals that they are governed by a surprisingly simple relationship between frequency of occurrence and the degree to which they propagate along the citation graph. We propose a simple formalization of this pattern and validate it with data from close to 50 million publication records from the Web of Science, PubMed Central, and the American Physical Society. Evaluations relying on human annotators, citation network randomizations, and comparisons with several alternative approaches confirm that our formula is accurate and effective, without a dependence on linguistic or ontological knowledge and without the application of arbitrary thresholds or filters.

  14. What is the dimension of citation space?

    Science.gov (United States)

    Clough, James R.; Evans, Tim S.

    2016-04-01

    Citation networks represent the flow of information between agents. They are constrained in time and so form directed acyclic graphs which have a causal structure. Here we provide novel quantitative methods to characterise that structure by adapting methods used in the causal set approach to quantum gravity by considering the networks to be embedded in a Minkowski spacetime and measuring its dimension using Myrheim-Meyer and Midpoint-scaling estimates. We illustrate these methods on citation networks from the arXiv, supreme court judgements from the USA, and patents and find that otherwise similar citation networks have measurably different dimensions. We suggest that these differences can be interpreted in terms of the level of diversity or narrowness in citation behaviour.

  16. Rescaling citations of publications in Physics

    CERN Document Server

    Radicchi, Filippo

    2010-01-01

    We analyze the citation distributions of all papers published in Physical Review journals between 1985 and 2009. The average number of citations received by papers published in a given year and in a given field is computed. Large variations are found, showing that it is not fair to compare citation numbers across fields and years. However, when a rescaling procedure by the average is used, it is possible to compare impartially articles across years and fields. We make the rescaling factors available, for use by the readers. We also show that rescaling citation numbers by the number of publication authors has strong effects and should therefore be taken into account when assessing the bibliometric performance of researchers.

  17. Homophily and missing links in citation networks

    CERN Document Server

    Ciotti, Valerio; Nicosia, Vincenzo; Panzarasa, Pietro; Latora, Vito

    2015-01-01

    Citation networks have been widely used to study the evolution of science through the lenses of the underlying patterns of knowledge flows among academic papers, authors, research sub-fields, and scientific journals. Here we focus on citation networks to cast light on the salience of homophily, namely the principle that similarity breeds connection, for knowledge transfer between papers. To this end, we assess the degree to which citations tend to occur between papers that are concerned with seemingly related topics or research problems. Drawing on a large data set of articles published in the journals of the American Physical Society between 1893 and 2009, we propose a novel method for measuring the similarity between articles through the statistical validation of the overlap between their bibliographies. Results suggest that the probability of a citation made by one article to another is indeed an increasing function of the similarity between the two articles. Our study also enables us to uncover missing ci...

  18. Median Citation Index vs Journal Impact Factor

    Science.gov (United States)

    Antonoyiannakis, Manolis

    2015-03-01

    The Journal Impact Factor is an arithmetic mean: It is the average number of citations, in a year, to a journal's articles that were published the previous two years. But for the vast majority of scholarly journals, the distribution of these citations is skewed (non-symmetric). We argue that a more representative member of the skewed distribution of citations is its median, not the mean. We thus introduce the Median Citation Index (MCI) and compare it to the journal Impact Factor (JIF) as a potentially more suitable choice of the ``center'' of the distribution, or its typical value. Unlike the JIF, the MCI is far less sensitive to outlier (very highly cited) papers or to gaming, and does not lend itself to the hype of calculating it to three decimal digits.

  19. The importance of proper citation of references in biomedical articles.

    Science.gov (United States)

    Masic, Izet

    2013-01-01

    In scientific circles, the reference is the information that is necessary to the reader in identifying and finding used sources. The basic rule when listing the sources used is that references must be accurate, complete and should be consistently applied. On the other hand, quoting implies verbatim written or verbal repetition of parts of the text or words written by others that can be checked in original. Authors of every new scientific article need to explain how their study or research fits with previous one in the same or similar fields. A typical article in the health sciences refers to approximately 20-30 other articles published in peer reviewed journals, cite once or hundreds times. Citations typically appear in two formats: a) as in-text citations where the sources of information are briefly identified in the text; or b) in the reference list at the end of the publication (book chapter, manuscript, article, etc.) that provides full bibliographic information for each source. Group of publishers met in Vancouver in 1978 and decided to prescribe uniform technical propositions for publication. Adopted in the 1979 by the National Library of Medicine in Bethesda, then the International Committee of Medical Journals Editors (ICMJE), whose review in 1982 entered the official application by 300 international biomedical journals. Authors writing articles for publication in biomedical publications used predominantly citation styles: Vancouver style, Harward style, PubMed style, ICMJE, APA, etc. The paper gives examples of all of these styles of citation to the authors in order to facilitate their applications. Also in this paper is given the review about the problem of plagiarism which becomes more common in the writing of scientific and technical articles in biomedicine. PMID:24167381

    Air quality model can be an adequate tool for future air quality prediction,also atmospheric observations supporting and emission control strategies responders.The influence of emission control policy (emission reduction targets in the national "China's 12th Five-Year Plan (2011-2015)") on the air quality in the near future over an important industrial city of China,Xuanwei in Yunnan Province,was studied by applying the AERMOD modeling system.First,our analysis demonstrated that the AERMOD modeling system could be used in the air quality simulation in the near future for SO2 and NOx under average meteorology but not for PM10.Second,after evaluating the simulation results in 2008 and 2015,ambient concentration of SO2,NOx and PM 10 (only 2008) were all centered in the middle of simulation area where the emission sources concentrated,and it is probably because the air pollutions were source oriented.Last but not least,a better air quality condition will happen under the hypothesis that the average meteorological data can be used in near future simulation.However,there are still heavy polluted areas where ambient concentrations will exceed the air quality standard in near future.In spatial allocation,reduction effect of SO2 is more significant than NOx in 2015 as the contribution of SO2 from industry is more than NOx.These results inspired the regulatory applications of AERMOD modeling system in evaluating environmental pollutant control policy

  14. Latest DVCS Results from HERMES

    CERN Document Server

    Yaschenko, Sergey

    2010-01-01

    Hard exclusive leptoproduction of real photons on nucleons and nuclei, Deeply Virtual Compton Scattering (DVCS), is one of the theoretically cleanest ways to access Generalized Parton Distributions (GPDs). During 1996–2006 the HERMES experiment at DESY, Hamburg, collected data on DVCS utilizing the HERA polarized electron or positron beams with energies of 27.6 GeV, and longitudinally and transversely polarized or unpolarized gas targets (H, D or heavier nuclei). The azimuthal asymmetries measured in the DVCS process allow access to the imaginary and/or real part of certain combinations of GPDs. An overview of the latest HERMES results on DVCS is presented.

  15. Patterns of database citation in articles and patents indicate long-term scientific and industry value of biological data resources.

    2016-01-01

    Data from open access biomolecular data resources, such as the European Nucleotide Archive and the Protein Data Bank are extensively reused within life science research for comparative studies, method development and to derive new scientific insights. Indicators that estimate the extent and utility of such secondary use of research data need to reflect this complex and highly variable data usage. By linking open access scientific literature, via Europe PubMedCentral, to the metadata in biological data resources we separate data citations associated with a deposition statement from citations that capture the subsequent, long-term, reuse of data in academia and industry.  We extend this analysis to begin to investigate citations of biomolecular resources in patent documents. We find citations in more than 8,000 patents from 2014, demonstrating substantial use and an important role for data resources in defining biological concepts in granted patents to both academic and industrial innovators. Combined together our results indicate that the citation patterns in biomedical literature and patents vary, not only due to citation practice but also according to the data resource cited. The results guard against the use of simple metrics such as citation counts and show that indicators of data use must not only take into account citations within the biomedical literature but also include reuse of data in industry and other parts of society by including patents and other scientific and technical documents such as guidelines, reports and grant applications.

    2013-05-01

    Full Text Available Analyzing the structure of research articles and th e relationship between the articles has always been important in bibliometrics research area. One of the methods for analyzing articles is by its citation. Normally researchers rank the article based on the citation count. But this quantity based evaluation is not sufficient due to various c itation types like Random citation, Guest citation. Our paper aims in providing a new method to rate a research paper based on its citation quality. In order to find the citation qua lity, three different semantic related processes are used: Citation classification, Citation Sentime nt Analysis, Content Relevancy. This work analyzes some challenges found in citing a research paper. We have proposed methods to figure out the valid citations for research paper and ther eby found quality of the research paper.

  17. Universality of citation distributions for academic institutions and journals

    CERN Document Server

    Chatterjee, Arnab; 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 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 that there are at least two distinct classes of journals across disciplines, depending on the form of the distribution function. We observe that a group of journals with high impact factor and average citations that are distinct from the majority of the j...

    2014-01-01

    We have collected and cleaned two network data sets: Coauthorship and Citation networks for statisticians. The data sets are based on all research papers published in four of the top journals in statistics from 2003 to the first half of 2012. We analyze the data sets from many different perspectives, focusing on (a) productivity, patterns and trends, (b) centrality, and (c) community structures, and present an array of interesting findings. For (a), we find that over the 10-year period, both the average number of papers per author and the fraction of self citations have been decreasing, but the proportion of distant citations has been increasing. These suggest that the statistics community has become increasingly more collaborative, competitive, and globalized, driven by the boom of online resources and Search Engines. For (b), we identify the most prolific, the most collaborative, and the most highly cited authors. We also identify a handful of "hot" papers and suggest "Variable Selection" and several other ...

    2016-01-01

    We study the statistics of citations made to the indexed Science journals in the Journal Citation Reports during the period 2004-2013 using different measures. We consider different measures which quantify the impact of the journals. To our surprise, we find that the apparently uncorrelated measures, even when defined in an arbitrary manner, show strong correlations. This is checked over all the years considered. Impact factor being one of these measures, the present work raises the question whether it is actually a nearly perfect index as claimed often. In addition we study the distributions of the different indices which also behave similarly.

  4. High Citation of Iranian Coauthored articles in comparison with single authored ones: does it link with self-citation

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available The aim of this research was to investigate the effect of co-authorship and self-citation on the citation rates of Iranian indexed articles in Web of Science (WoS. Research population included Iranian indexed articles in WoS in 2007 which had been received at least one citation. Numbers of articles in the time of research (October & November 2010 was 7355, which 390 of them, using stratified random sampling, was selected as sample. Research results showed that co-authored articles have received more citations than single-authored ones and this difference was statistically significant. On the other hand, self-citation exclusion has significantly reduced the citation rates of both co-authored and single-authored articles. After self-citation exclusion, existing difference between citation rates of co-authored and single-authored articles lost its significance. So, it can be concluded that self-citation exclusion led to reduction of citation rates of Iranian indexed articles in WoS, but this exclusion affected co-authored articles citation rates more than single-authored ones. In other words, high citation of Iranian co-authored articles in comparison with single-authored articles has been affected mainly by self-citation, not by foreign citation. This finding, which was our contribution, contradicted with results of previous researches.

  10. Citation pattern of newsworthy research articles

    Directory of Open Access Journals (Sweden)

    Manjari Manisha

    2015-01-01

    Full Text Available Popular science magazines cover research articles published in scholarly journals that the magazines perceive as having news value. Despite thousands of research articles being published in research journals, a very few get identified for coverage in popular science magazines, general magazines, and newspapers. Do research articles published in journals that are covered in popular science magazines receive higher citations? We hypothesize that newsworthy articles should receive higher citations as the newsworthiness can be a reflection of higher research value of the articles and also because of the visibility received by the articles owing to its coverage in popular science magazine. To empirically study the citedness, we identified 193 research articles and that were reported in New Scientist magazine in 2001. The characteristics of these articles including the citations received following coverage in New Scientist in 2001 were looked at. It was found that average citations per paper of articles covered in New Scientist was higher than the journal average for the year 2001 for 19 out of the 24 journals identified here.

The novel concept of Citation Mining, a combination of citation bibliometrics and text mining, is used for the phenomenological description. Citation Mining starts with a group of core papers whose impact is to be examined, retrieves the papers that cite these core papers, and then analyzes the technical infrastructure (authors, jorunals, institutions) of the citing papers as well as their thematic characteristics.

  20. The Structure and Dynamics of Co-Citation Clusters: A Multiple-Perspective Co-Citation Analysis

    CERN Document Server

    Chen, Chaomei; Hou, Jianhua

    2010-01-01

    A multiple-perspective co-citation analysis method is introduced for characterizing and interpreting the structure and dynamics of co-citation clusters. The method facilitates analytic and sense making tasks by integrating network visualization, spectral clustering, automatic cluster labeling, and text summarization. Co-citation networks are decomposed into co-citation clusters. The interpretation of these clusters is augmented by automatic cluster labeling and summarization. The method focuses on the interrelations between a co-citation cluster's members and their citers. The generic method is applied to a three-part analysis of the field of Information Science as defined by 12 journals published between 1996 and 2008: 1) a comparative author co-citation analysis (ACA), 2) a progressive ACA of a time series of co-citation networks, and 3) a progressive document co-citation analysis (DCA). Results show that the multiple-perspective method increases the interpretability and accountability of both ACA and DCA n...

    2015-11-01

    Citations to scholarly items are building bricks for multidisciplinary science communication. Citation analyses are currently influencing individual career advancement and ranking of academic and research institutions worldwide. This article overviews the involvement of scientific authors, reviewers, editors, publishers, indexers, and learned associations in the citing and referencing to preserve the integrity of science communication. Authors are responsible for thorough bibliographic searches to select relevant references for their articles, comprehend main points, and cite them in an ethical way. Reviewers and editors may perform additional searches and recommend missing essential references. Publishers, in turn, are in a position to instruct their authors over the citations and references, provide tools for validation of references, and open access to bibliographies. Publicly available reference lists bear important information about the novelty and relatedness of the scholarly items with the published literature. Few editorial associations have dealt with the issue of citations and properly managed references. As a prime example, the International Committee of Medical Journal Editors (ICMJE) issued in December 2014 an updated set of recommendations on the need for citing primary literature and avoiding unethical references, which are applicable to the global scientific community. With the exponential growth of literature and related references, it is critically important to define functions of all stakeholders of science communication in curbing the issue of irrational and unethical citations and thereby improve the quality and indexability of scholarly journals.

    Since the beginning of this century, humanity has been facing a new emerging, or re-emerging, virus threat almost every year: West Nile, Influenza A, avian flu, dengue, Chikungunya, SARS, MERS, Ebola, and now Zika, the latest newcomer. Zika virus (ZIKV), a flavivirus transmitted by Aedes mosquitoes, was identified in 1947 in a sentinel monkey in Uganda, and later on in humans in Nigeria. The virus was mainly confined to the African continent until it was detected in south-east Asia the 1980’s, then in the Micronesia in 2007 and, more recently in the Americas in 2014, where it has displayed an explosive spread, as advised by the World Health Organization, which resulted in the infection of hundreds of thousands of people. ZIKV infection was characterized by causing a mild disease presented with fever, headache, rash, arthralgia, and conjunctivitis, with exceptional reports of an association with Guillain–Barre syndrome (GBS) and microcephaly. However, since the end of 2015, an increase in the number of GBS associated cases and an astonishing number of microcephaly in fetus and new-borns in Brazil have been related to ZIKV infection, raising serious worldwide public health concerns. Clarifying such worrisome relationships is, thus, a current unavoidable goal. Here, we extensively review what is currently known about ZIKV, from molecular biology, transmission routes, ecology, and epidemiology, to clinical manifestations, pathogenesis, diagnosis, prophylaxis, and public health.

    Golosovsky, Michael

    2014-01-01

    We demonstrate a comprehensive framework that accounts for citation dynamics of scientific papers and for the age distribution of references. We show that citation dynamics of scientific papers is nonlinear and this nonlinearity has far-reaching consequences, such as diverging citation distributions and runaway papers. We propose a nonlinear stochastic dynamic model of citation dynamics based on link copying/redirection mechanism. The model is fully calibrated by empirical data and does not contain free parameters. This model can be a basis for quantitative probabilistic prediction of citation dynamics of individual papers and of the journal impact factor.

  17. Central indexes to the citation distribution: A complement to the h-index

    CERN Document Server

    Dorta-Gonzalez, Pablo; 10.1007/s11192-011-0453-3

    2013-01-01

    The citation distribution of a researcher shows the impact of their production and determines the success of their scientific career. However, its application in scientific evaluation is difficult due to the bi-dimensional character of the distribution. Some bibliometric indexes that try to synthesize in a numerical value the principal characteristics of this distribution have been proposed recently. In contrast with other bibliometric measures, the biases that the distribution tails provoke, are reduced by the h-index. However, some limitations in the discrimination among researchers with different publication habits are presented in this index. This index penalizes selective researchers, distinguished by the large number of citations received, as compared to large producers. In this work, two original sets of indexes, the central area indexes and the central interval indexes, that complement the h-index to include the central shape of the citation distribution, are proposed and compared.

  18. Do PageRank-based author rankings outperform simple citation counts?

    CERN Document Server

    Fiala, Dalibor; Žitnik, Slavko; Bajec, Marko

    2015-01-01

    The basic indicators of a researcher's productivity and impact are still the number of publications and their citation counts. These metrics are clear, straightforward, and easy to obtain. When a ranking of scholars is needed, for instance in grant, award, or promotion procedures, their use is the fastest and cheapest way of prioritizing some scientists over others. However, due to their nature, there is a danger of oversimplifying scientific achievements. Therefore, many other indicators have been proposed including the usage of the PageRank algorithm known for the ranking of webpages and its modifications suited to citation networks. Nevertheless, this recursive method is computationally expensive and even if it has the advantage of favouring prestige over popularity, its application should be well justified, particularly when compared to the standard citation counts. In this study, we analyze three large datasets of computer science papers in the categories of artificial intelligence, software engineering,...

    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.

  20. Universal hierarchical behavior of citation networks

    International Nuclear Information System (INIS)

    Many of the essential features of the evolution of scientific research are imprinted in the structure of citation networks. Connections in these networks imply information about the transfer of knowledge among papers, or, in other words, edges describe the impact of papers on other publications. This inherent meaning of the edges implies that citation networks can exhibit hierarchical features that are typical of networks based on decision making. In this paper, we investigate the hierarchical structure of citation networks consisting of papers in the same field. We find that the majority of the networks follow a universal trend towards a highly hierarchical state, and the various fields display differences only concerning (i) their phase in life (distance from the ‘birth’ of a field) or (ii) the characteristic time according to which they are approaching the stationary state. We also show by a simple argument that the alterations in the behavior are related to and can be understood by the degree of specialization corresponding to the fields. Our results suggest that during the accumulation of knowledge in a given field, some papers are gradually becoming relatively more influential than most other papers. (paper)

  1. On the evolution and utility of annual citation indices

    CERN Document Server

    Khaleque, Abdul; Sen, Parongama

    2014-01-01

    We study the statistics of citations made to the top ranked indexed journals for Science and Social Science databases in the Journal Citation Reports using different measures. Total annual citation and impact factor, as well as a third measure called the annual citation rate are used to make the detailed analysis. We observe that the distribution of the annual citation rate has an universal feature - it shows a maximum at the rate scaled by half the average, irrespective of how the journals are ranked, and even across Science and Social Science journals, and fits well to log-Gumbel distribution. Correlations between different quantities are studied and a comparative analysis of the three measures is presented. The newly introduced annual citation rate factor helps in understanding the effect of scaling the number of citation by the total number of publications. The effect of the impact factor on authors contributing to the journals as well as on editorial policies is also discussed.

    The purpose of this study is to analyze the relationship between citation ranking and peer evaluation in assessing senior faculty research performance. Other studies typically derive their peer evaluation data directly from referees, often in the form of ranking. This study uses two additional...... sources of peer evaluation data: citation content analysis and book review content analysis. Two main questions are investigated: (a) To what degree does citation ranking correlate with data from citation content analysis, book reviews, and peer ranking? (b) Is citation ranking a valid evaluative....... Analysis also shows that normalized citation ranking and citation content analysis, book reviews, and peer ranking perform similarly (i.e., are highly correlated) for high-ranked and low-ranked senior scholars.

  3. A small world of citations? The influence of collaboration networks on citation practices

    CERN Document Server

    Wallace, Matthew L; Gingras, Yves

    2011-01-01

    This paper examines the proximity of authors to those they cite using degrees of separation in a co-author network, essentially using collaboration networks to expand on the notion of self-citations. While the proportion of direct self-citations (including co-authors of both citing and cited papers) is relatively constant in time and across specialties in the natural sciences (10% of citations) and the social sciences (20%), the same cannot be said for citations to authors who are members of the co-author network. Differences between fields and trends over time lie not only in the degree of co-authorship which defines the large-scale topology of the collaboration network, but also in the referencing practices within a given discipline, computed by defining a propensity to cite at a given distance within the collaboration network. Overall, there is little tendency to cite those nearby in the collaboration network, excluding direct self-citations. By analyzing these social references, we characterize the social...

  4. Capturing citation activity in three health sciences departments: a comparison study of Scopus and Web of Science.

    Sarkozy, Alexandra; Slyman, Alison; Wu, Wendy

    2015-01-01

    Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed. PMID:25927511

    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

  8. Link Label Prediction in Signed Citation Network

    KAUST Repository

    Akujuobi, Uchenna

    2016-04-12

    Link label prediction is the problem of predicting the missing labels or signs of all the unlabeled edges in a network. For signed networks, these labels can either be positive or negative. In recent years, different algorithms have been proposed such as using regression, trust propagation and matrix factorization. These approaches have tried to solve the problem of link label prediction by using ideas from social theories, where most of them predict a single missing label given that labels of other edges are known. However, in most real-world social graphs, the number of labeled edges is usually less than that of unlabeled edges. Therefore, predicting a single edge label at a time would require multiple runs and is more computationally demanding. In this thesis, we look at link label prediction problem on a signed citation network with missing edge labels. Our citation network consists of papers from three major machine learning and data mining conferences together with their references, and edges showing the relationship between them. An edge in our network is labeled either positive (dataset relevant) if the reference is based on the dataset used in the paper or negative otherwise. We present three approaches to predict the missing labels. The first approach converts the label prediction problem into a standard classification problem. We then, generate a set of features for each edge and then adopt Support Vector Machines in solving the classification problem. For the second approach, we formalize the graph such that the edges are represented as nodes with links showing similarities between them. We then adopt a label propagation method to propagate the labels on known nodes to those with unknown labels. In the third approach, we adopt a PageRank approach where we rank the nodes according to the number of incoming positive and negative edges, after which we set a threshold. Based on the ranks, we can infer an edge would be positive if it goes a node above the

  9. The normalization of citation counts based on classification systems

    CERN Document Server

    Bornmann, Lutz; Barth, Andreas

    2013-01-01

    If we want to assess whether the paper in question has had a particularly high or low citation impact compared to other papers, the standard practice in bibliometrics is to normalize citations in respect of the subject category and publication year. A number of proposals for an improved procedure in the normalization of citation impact have been put forward in recent years. Against the background of these proposals this study describes an ideal solution for the normalization of citation impact: in a first step, the reference set for the publication in question is collated by means of a classification scheme, where every publication is associated with a single principal research field or subfield entry (e. g. via Chemical Abstracts sections) and a publication year. In a second step, percentiles of citation counts are calculated for this set and used to assign the normalized citation impact score to the publications (and also to the publication in question).

    Nobel Prizes are commonly seen to be among the most prestigious achievements of our times. Based on mining several million citations, we quantitatively analyze the processes driving paradigm shifts in science. We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur, from continuous scientific progress all the way up to scientific revolutions, which change the way we see our world. Measuring the "boosting effect" of landmark papers, our analysis reveals how new ideas and new players can make their...

  1. Patent citation network in nanotechnology (1976-2004)

    International Nuclear Information System (INIS)

    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

Here, we describe the current patterns of how database entries are cited in research articles, based on analysis of the full text Open Access articles available from Europe PMC. Focusing on citation of entries in the European Nucleotide Archive (ENA), UniProt and Protein Data Bank, Europe (PDBe), we demonstrate that text mining doubles the number of structured annotations of database record citations supplied in journal articles by publishers. Many thousands of new literature-database relationships are found by text mining, since these relationships are also not present in the set of articles cited by database records. We recommend that structured annotation of database records in articles is extended to other databases, such as ArrayExpress and Pfam, entries from which are also cited widely in the literature. The very high precision and high-throughput of this text-mining pipeline makes this activity possible both accurately and at low cost, which will allow the development of new integrated data services.

    Do you write code for your research? Use astronomical software? Do you wish there were a better way of citing, sharing, archiving, or discovering software for astronomy research? You're not alone! In April 2015, AAS's publishing team joined other leaders in the astronomical software community in a meeting funded by the Sloan Foundation, with the purpose of discussing these issues and potential solutions. In attendance were representatives from academic astronomy, publishing, libraries, for-profit software sharing platforms, telescope facilities, and grantmaking institutions. The goal of the group was to establish “protocols, policies, and platforms for astronomical software citation, sharing, and archiving,” in the hopes of encouraging a set of normalized standards across the field. The AAS is now collaborating with leaders at GitHub to write grant proposals for a project to develop strategies for software discoverability and citation, in astronomy and beyond. If this topic interests you, you can find more details in this document released by the group after the meeting: http://astronomy-software-index.github.io/2015-workshop/ The group hopes to move this project forward with input and support from the broader community. Please share the above document, discuss it on social media using the hashtag #astroware (so that your conversations can be found!), or send private comments to julie.steffen@aas.org.

  6. Patterns of database citation in articles and patents indicate long-term scientific and industry value of biological data resources [version 1; referees: 2 approved

    Directory of Open Access Journals (Sweden)

    David Bousfield

    2016-02-01

    Full Text Available Data from open access biomolecular data resources, such as the European Nucleotide Archive and the Protein Data Bank are extensively reused within life science research for comparative studies, method development and to derive new scientific insights. Indicators that estimate the extent and utility of such secondary use of research data need to reflect this complex and highly variable data usage. By linking open access scientific literature, via Europe PubMedCentral, to the metadata in biological data resources we separate data citations associated with a deposition statement from citations that capture the subsequent, long-term, reuse of data in academia and industry.  We extend this analysis to begin to investigate citations of biomolecular resources in patent documents. We find citations in more than 8,000 patents from 2014, demonstrating substantial use and an important role for data resources in defining biological concepts in granted patents to both academic and industrial innovators. Combined together our results indicate that the citation patterns in biomedical literature and patents vary, not only due to citation practice but also according to the data resource cited. The results guard against the use of simple metrics such as citation counts and show that indicators of data use must not only take into account citations within the biomedical literature but also include reuse of data in industry and other parts of society by including patents and other scientific and technical documents such as guidelines, reports and grant applications.

    Full Text Available Acoustics-based methods offer a powerful tool for sensing applications. Acoustic sensors can be applied in many fields ranging from materials characterization, structural health monitoring, acoustic imaging, defect characterization, etc., to name just a few. A proper selection of the acoustic wave frequency over a wide spectrum that extends from infrasound (<20 Hz up to ultrasound (in the GHz–band, together with a number of different propagating modes, including bulk longitudinal and shear waves, surface waves, plate modes, etc., allow acoustic tools to be successfully applied to the characterization of gaseous, solid and liquid environments. The purpose of this special issue is to provide an overview of the research trends in acoustic wave sensing through some cases that are representative of specific applications in different sensing fields.

  12. The Citation Field of Evolutionary Economics

    CERN Document Server

    Dolfsma, Wilfred

    2010-01-01

    Evolutionary economics has developed into an academic field of its own, institutionalized around, amongst others, the Journal of Evolutionary Economics (JEE). This paper analyzes the way and extent to which evolutionary economics has become an interdisciplinary journal, as its aim was: a journal that is indispensable in the exchange of expert knowledge on topics and using approaches that relate naturally with it. Analyzing citation data for the relevant academic field for the Journal of Evolutionary Economics, we use insights from scientometrics and social network analysis to find that, indeed, the JEE is a central player in this interdisciplinary field aiming mostly at understanding technological and regional dynamics. It does not, however, link firmly with the natural sciences (including biology) nor to management sciences, entrepreneurship, and organization studies. Another journal that could be perceived to have evolutionary acumen, the Journal of Economic Issues, does relate to heterodox economics journa...

  15. 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.

  16. Data Publication & Citation practices in Astronomy

    Science.gov (United States)

    Muench, August

    2011-05-01

    We investigated author behaviors around the practices of publishing and citing data products within refereed astronomical journals. We set the scope of this investigation to encompass AAS publications over the last decade, including the AAS publisher transition that took place in 2008-09. Our analysis focused on parsing the journal articles’ source material (LaTeX, XML) to catalog hyperlinks between the published text and extended data products that were provided by authors as part of the standard editorial process for refereed publications. We quantitatively and rhetorically analyzed this catalog of hyperlinks to decipher (some of) the authors’ behaviors with regard to data citation and publication. We focused on authors’ adoption and utilization of two specific data-literature links: journal hosted supplementary material and the NASA ADEC recommended system of dataset "identifiers,” which were designed to provide persistent links between articles and packages of relevant, reusable data located at trusted, established astronomy archives. These types of hyperlinks are, however, minor subsets of the overall catalog, where the bulk of author inserted links provide descriptive elements to otherwise "unpublished” material but not to unique, reusable datasets. In general our investigation reveals a consistent level of effort by authors to cite and publish some data products, although case by case examples darkly illuminate individual author's experiences with data publication and citation within the standard editorial process. Finally, we point out a couple of functional issues with existing data-literature links as specifically related to the suite of author behaviors examined in this project.

  17. Two Decades of Research on Strategic Alliances: Analysis of Citations, Co-citations and Themes Researched

    Directory of Open Access Journals (Sweden)

    Manuel Portugal Ferreira

    2014-12-01

    Full Text Available Research on strategic alliances has a long tradition in management studies. Strategic alliances have been investigated using multiple theoretical lenses from RBV to agency and transaction cost, and diverse contexts, from the semiconductor to airline industries. In this study we scrutinize the extant strategic alliance research in thirtyone top-ranked business/management journals, over a twenty-year period, from 1993 to 2012. In a sample of 866 articles we conducted citation and co-citation analyses employing social network techniques and factor analysis to identify research themes and make sense of the stock of accumulated knowledge and theoretical trends. We were able to identify some shifts in research over time, namely from a focus on performance and theoretical emphasis on transaction cost theory and governance concerns, moving to a learning and knowledge transfer approach, social networks and collaboration. This study provides the foundations over which future research may develop to fill conceptual and empirical gaps.

  18. The incidence and role of negative citations in science.

    2015-11-10

    Citations to previous literature are extensively used to measure the quality and diffusion of knowledge. However, we know little about the different ways in which a study can be cited; in particular, are papers cited to point out their merits or their flaws? We elaborated a methodology to characterize "negative" citations using bibliometric data and natural language processing. We found that negative citations concerned higher-quality papers, were focused on a study's findings rather than theories or methods, and originated from scholars who were closer to the authors of the focal paper in terms of discipline and social distance, but not geographically. Receiving a negative citation was also associated with a slightly faster decline in citations to the paper in the long run. PMID:26504239

  19. Robustness and discriminatory strength of citation-based journal indicators

    DEFF Research Database (Denmark)

    Andersen, Jens Peter; Christensen, Anette Luther

    AIM: A plethora of journal indicators exists, and are used e.g. in national assessment exercises as part of the basis for university funding. Recent studies report as many as 39 indicators of which the major part are citation based. While studies have shown these citation-based journal indicators...... to correlate, it is assumed that some indicators may be better at discriminating “good” from “bad” journals, and it is consequently assumed that some indicators are more robust than other. This study aims at describing these attributes for a selection of the most promising and/or most used citation-based...... journal indicators. METHODS: We use Bayes' theorem to illustrate the connection between journal indicators and the underlying citations. This method is closely related to that of Lehmann, Jackson & Lautrup (2006). This is a work in progress. MATERIALS: Complete citation data from Web of Science for select...

    Dongeuibogam is the most prestigious traditional medical book in Korea, written by Heo Joon, who codified it by picking the essence of Chinese traditional medical books before the Ming Dynasty and some other ancient Chinese books and sorted them out. Among the citations of this book, those marked as"Herbal" is more complicated. We made a preliminary research on the citations of such Herbal, from their distribution, sources, citation manners, pharmacological features, to find that 23 rolls of main text to include citations of Herbal in each roll. We also found that most Herbal referred by Heo Joon come from Zheng lei ben cao (Classified Materia Medica), and a few of the contents are mixed with the contents of other medical books. Heo Joon abstracted and modified the citations from the source literature, embodying his ideas of pursuing conciseness and practicability. PMID:25429883

    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...

    This bibliography contains citations concerning media and surfaces to produce an optical phase-conjugate wave. The phase-conjugate mirrors can be liquid, compressed gas, glass, or crystal. Phase conjugation, producing an ideal light beam by reversing the beam and passing it through a medium which on the first pass produced distortions, has recently moved from the laboratory and is now being used for practical applications. Some applications include holography, high-energy laser beams for plasma diagnostics, and laser heating of plasmas. The citations include stimulated Brillouin scattering and four-wave mixing as methods for phase conjugation.

  4. Latest approaches of Kyoto protocol

    International Nuclear Information System (INIS)

    Recently EURELECTRIC welcome the proposal of new EC Directive concerning the inclusion in the EU Emissions Trading Scheme (ETS) of credits from the project mechanisms - Joint Implementation (JI) and Clean Development Mechanism (CDM). The proposed Directive is an amendment to the EU Emissions Trading Directive adopted in June 2003. EURELECTRIC calls for unlimited use of credits in ETS. The draft Directive provides for the application of these mechanisms to begin as of 2008, on condition that the Kyoto Protocol does actually enter into force, an event which is still dependent on Russia's ratification. Such ratification has been subject to contradictory statements from the Russian Government, and the question of whether their signature to the Protocol is forthcoming is still fraught with uncertainty. Although it is not anticipated that significant quantities of JI or CDM certified credits will be available in the period 2005-2007, those that do become available would provide some additional liquidity in the emissions trading market. There is a direct relation between the coming ETS and electricity pricing: environmental policy is the driver, based on the need to switch to a low-carbon future and manage the necessary investments in a rational manner - and emissions trading is the best solution available. Romania has good opportunities to be involved in the greenhouse gases market, both in ETS and JI mechanisms. Some JI projects between Romanian and The Netherlands are already done or underway.

  5. Latest findings of RASPLAV project

    International Nuclear Information System (INIS)

    The main activity directions and results obtained in the course of investigations within the first stage of the RASPLAV project are discussed. The general aim of the RASPLAV project is to study into the processes taking place at PWR reactor severe accident stage when melt pool forms after reactor core meltdown and flowing down on reactor vessel bottom. Such accident development was observed during the Three Mile Island unit 2 accident in 1979. The RASPLAV-AW-200 experimental facility built basing on original engineering decisions and large number of calculations is described. The facility experimental section represents a narrow chamber 0.116 m wide having cylindrical bottom with radius of 0.4 m containing about 200 kg of melt. The main results obtained during experiments in the RASPLAV facility are considered. Those include measuring the physical properties for reactor core melts of different composition such as viscosity, heat and electric conductivity and melting temperature at temperatures up to 2850 deg C. Differences in melt behaviour as compared with that of modelling liquid at temperatures higher than 2650 deg C are revealed. The melt stratification and noticeable changes in distribution of the uranium-to-zirconium ratio over the slab height for the melt different compositions are shown. The conclusion on applicability of the results obtained for verification and development of analytical and computer approaches for simulation of the processes discussed is made

The majority of confirmed incidents with nuclear materials recorded during 1993-2004 involved criminal activity, such as theft, illegal possession, illegal transfer or transaction. Some of these incidents indicate that there is a perceived demand for such materials on the 'black market'. Where information on motives is available, it indicates that profit seeking is the principal motive behind such events. Chart can be viewed: Incidents involving nuclear materials confirmed to the ITDB (1993-2004). Radioactive Materials. From 1993-2004, a total of 424 incidents were reported involving other radioactive materials mostly in the form of radioactive sources. Radioactive sources are used worldwide in a host of legitimate applications while measures to protect and control their use, storage or disposal are much less strict than those applied toward nuclear materials. In the hands of terrorists or other criminals, some radioactive sources could be used for malicious purposes, for example in a radiological dispersal device or 'dirty bomb'. Uncontrolled radioactive sources also have the potential to harm human health or the environment. Unlawfully discarded or disposed of radioactive sources, when melted at scrap metal recycle plants, may lead to severe environmental and economic related consequences. The majority of incidents involved radioisotopes and portable radioactive sources used for various industrial applications, such as gauging or radiography. Chart can be viewed: Incidents involving radioactive sources confirmed to the ITDB, by type of application (1993-2004). Activity levels of the majority of these sources were too low to pose serious radiological risk if used for malicious purposes. About 50 incidents involved high-risk 'dangerous' radioactive sources, which present considerable radiological danger if used in a malicious act. The overwhelming majority of incidents involving 'dangerous' sources were reported

    Full Text Available 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.

    It is hard to detect important articles in a specific context. Information retrieval techniques based on full text search can be inaccurate to identify main topics and they are not able to provide an indication about the importance of the article. Generating a citation network is a good way to find most popular articles but this approach is not context aware. The text around a citation mark is generally a good summary of the referred article. So citation context analysis presents an opportunity to use the wisdom of crowd for detecting important articles in a context sensitive way. In this work, we analyze citation contexts to rank articles properly for a given topic. The model proposed uses citation contexts in order to create a directed and weighted citation network based on the target topic. We create a directed and weighted edge between two articles if citation context contains terms related with the target topic. Then we apply common ranking algorithms in order to find important articles in this newly cre...

  16. Editorial - Wikipedia popularity from a citation analysis point of view

    Full Text Available This study aims to provide an overview of the citation rate of Wikipedia since its launch in 2004. It is worth noting that since its inception Wikipedia, the free international multi-lingual encyclopedia, has been subject to criticism (Fasoldt, 2004; Orlowski, 2005; Lipczynska, 2005. Wikipedia as a popular web resource appears in response to every keyword search on Google. One way to test the popularity of a web resource is to use citation analysis method to predict to what extend it is cited by scientific papers. This study tries to identify and quantify the number of citations to Wikipedia in the papers indexed by the ISI Web of Science, studying the citation behavior of authors who have published papers in journals indexed by this database. Another simple search was conducted in order to analyze the number of citations to Britannica in the Cited Work=(Britannica* AND Cited Year=(2004-2009. The result showed that Britannica was cited only 10 times by 10 different subject areas and only in English language documents. The data show that Wikipedia is cited 26 times more than Britannica. Although, the credibility and reliability of content of Wikipedia as an authoritative reference source was widely criticized (e.g., Lih, 2004; Andrew et al., 2005; Korfiatis, Poulos, & Bokos, 2006, it is cited more than Britannica. The significance of Wikipedia from a citation analysis point of view goes well beyond open access and enhanced opportunities for citation.

    The Marine Biological Laboratory/Woods Hole Oceanographic Institution (MBLWHOI) Library, the Scientific Committee on Oceanic Research (SCOR) and the International Oceanographic Data and Information Exchange (IODE) of the Intergovernmental Oceanographic Commission have assembled a team of librarians, data managers and scientists who are collaborating to identify best practices for tracking data provenance and clearly attributing credit to data collectors/providers. One successful outcome of this collaborative effort includes tools and procedures developed by the Marine Biological Laboratory/Woods Hole Oceanographic Institution (MBLWHOI) Library and the Biological and Chemical Oceanography Data Management Office (BCO-DMO) that automate the ingestion of metadata from BCO-DMO for deposit with a copy of each data set into the Institutional Repository (IR) Woods Hole Open Access Server (WHOAS). The system also incorporates functionality for BCO-DMO to request a Digital Object Identifier (DOI) from the Library. This partnership allows the Library to work with a trusted data repository to ensure high quality data while the data repository utilizes library services and is assured that a permanent archived copy of the data is associated with the persistent DOI. The assignment of persistent identifiers enables accurate data citation. The Library can assign a DOI to appropriate datasets deposited in WHOAS. We are particularly interested in working with authors to deposit datasets associated with published articles. The DOI would ideally be assigned before submission and be included in the published paper so readers can link directly to the dataset, but DOIs are also being assigned to datasets that support papers that have already been published. WHOAS metadata records link the article to the datasets and the datasets to the article. Because of the assignment of DOIs, Elsevier Publishing sought a collaboration with the Library. Article records in Science Direct now contain

  5. Citation indexing and evaluation of scientific papers.

    Science.gov (United States)

    Margolis, J

    1967-03-10

    Evaluation by means of citation patterns can be successful only insofar as published papers and their bibliographies reflect scientific activity and nothing else. Such an innocent descrip tion is becoming less and less tenable. The present scientific explosion gave rise to more than a proportional pub lication explosion, which not only re flects the scientific explosion but has its own dynamics and vicious circles. Publication of results is probably the main means of accomplishing the al most impossible task of accounting for time and money spent on research. Inevitably, this puts a premium on quantity at the expense of quality, and, as with any other type of inflation, the problem worsens: the more papers are written, the less they count for and the greater is the pressure to publish more. What makes matters worse is the fact that the sheer volume of the"litera ture" makes it increasingly difficult to separate what is worthwhile from the rest. Critical reviews have become somewhat of a rarity, and editorial judgment is usually relegated to ref erees, who are contemporaries and, per haps, competitors of the authors-a situation which has its own undesirable implications (11, 18). It requires little imagination to discover other vicious circles, all arising from distortion of the primary reasons for publishing the results of scientific inquiry. There are, it is true, signs of ad justment to this crisis, partly due to some easing of the pressure to pub lish at all costs, and partly due to the readers' changing attitudes toward the flood of publications. An increasing amount of research is now being car ried out in the form of collective proj ects in large institutions where publica tion is no longer the standard method of accounting for individual work. At the same time there is apparent an in creasing tendency for scientific journals to polarize into the relatively few leading ones which carry important informa tion and the many subsidiary journals which serve as

  6. CWTS crown indicator measures citation impact of a research group's publication oeuvre

    Moed, Henk F

    2010-01-01

    The article "Caveats for the journal and field normalizations in the CWTS (`Leiden') evaluations of research performance", published by Tobias Opthof and Loet Leydesdorff (arXiv:1002.2769) deals with a subject as important as the application of so called field normalized indicators of citation impact in the assessment of research performance of individual researchers and research groups. Field normalization aims to account for differences in citation practices across scientific-scholarly subject fields. As the primary author of the papers presenting the "Leiden" indicators and of many reports and articles reporting on the outcomes of assessments actually using these measures, I comment on the 3 main issues addressed in the paper by Opthof and Leydesdorff.

  7. Considerations on patent valuation based on patent classification and citation in biotechnological field

    Science.gov (United States)

    Mihara, Kenji

    Regarding innovation measurement utilizing patent information, a number of researchers are making great efforts to measure a "patent value (patent quality)." For patent valuation, patent classification and citation are often utilized as patent information. Also, biotechnological field is attracting attention from the viewpoint of application to environmental or medical study, and considerable researches on patent valuation are ongoing in this technical field. However, it is not enough recognized that researchers cannot be too careful when they deal with classification information in the biotech field because patent classification structure in this field is not well-established. And also, it is not known enough that citation patterns of both academic papers and patent documents are so complicated that the patterns cannot be easily generalized. In this article, the issues above were verified from a position based on working experiences of biotech patent examiner at Japan Patent Office, and considerations and implications were given on what patent valuation should be.

  10. Indicators of the Interdisciplinarity of Journals: Diversity, Centrality, and Citations

    CERN Document Server

    Leydesdorff, Loet

    2010-01-01

    A citation-based indicator for interdisciplinarity has been missing hitherto among the set of available journal indicators. In this study, we investigate betweenness centrality, entropy, the Gini coefficient, and more recently proposed measures for diversity that combine the statistics of vectors and distances in networks, in terms of their potential to fill this gap. The effects of various normalizations are specified and measured using the matrix of 8,207 journals contained in the Journal Citation Reports of the (Social) Science Citation Index. Betweenness centrality in (1-mode) affiliations networks provides an indicator outperforming betweenness in the (2-mode) citation network. Entropy as a vector-based indicator performs better than the Gini coefficient, but is sensitive to size. Science and Nature, for example, are indicated at the top of the list. The new diversity measure provides reasonable results when (1 - cosine) is assumed as a measure for the distance, but results using Euclidean distances are ...

  11. Beyond citations: Scholars' visibility on the social Web

    Bar-Ilan, Judit; Peters, Isabella; Priem, Jason; Shema, Hadas; Terliesner, Jens

    2012-01-01

    Traditionally, scholarly impact and visibility have been measured by counting publications and citations in the scholarly literature. However, increasingly scholars are also visible on the Web, establishing presences in a growing variety of social ecosystems. But how wide and established is this presence, and how do measures of social Web impact relate to their more traditional counterparts? To answer this, we sampled 57 presenters from the 2010 Leiden STI Conference, gathering publication and citations counts as well as data from the presenters' Web "footprints." We found Web presence widespread and diverse: 84% of scholars had homepages, 70% were on LinkedIn, 23% had public Google Scholar profiles, and 16% were on Twitter. For sampled scholars' publications, social reference manager bookmarks were compared to Scopus and Web of Science citations; we found that Mendeley covers more than 80% of sampled articles, and that Mendeley bookmarks are significantly correlated (r=.45) to Scopus citation counts.

    Ming-Yueh Tsay

    2014-04-01

    Full Text Available Using informetrics and citation analysis, the present study explores and compares characteristics and types of citations in the humanity journal articles that published in Taiwan. Research articles published in 2011, from top humanity journals, assessed by the Institute of Humanities and Social Sciences, National Science Council in Taiwan, were collected and analyzed. The analysis was done by structure of journal article and location of citations. In addition to citations appearing in the text, the phenomena of citation type will be compared and discussed in the latter part. The results of this study revealed articles of literature, history, philosophy and arts were mostly argumentative, while linguistic articles tended to comply with IMRAD (Introduction, Methods and Materials, Results,And Discussion formats. Introducing primary materials from original works, humanity scholars tended to cite for factual descriptions or to support authors’ perspectives. Secondary materials, such as later studies on the original works by other scholars, were seen the most in the disciplines of linguistics while the least in that of history. In general, the distribution of citation types is similar between articles in domestic and foreign journals; merely minor differences occurred among disciplines. While citing characteristics and information needs of humanities scholars revealed in this study may contribute to collection development of libraries or refinement of information services to researchers, suggestions based on analysis of research results may also serve as reference for standardization of writing and publication of journal articles in Taiwan. Aiming at further exploration of citations, this study is expected to provide a better understanding of the nature of citations and to serve as a foundation for future empirical studies.

  19. The Scientific Impact of Nations: Journal Placement and Citation Performance

    Science.gov (United States)

    Smith, Matthew J.; Weinberger, Cody; Bruna, Emilio M.; Allesina, Stefano

    2014-01-01

    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. PMID:25296039

    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.

    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 discriminat...

  8. How citation boosts promote scientific paradigm shifts and nobel prizes.

    Directory of Open Access Journals (Sweden)

    Amin Mazloumian

    Full Text Available Nobel Prizes are commonly seen to be among the most prestigious achievements of our times. Based on mining several million citations, we quantitatively analyze the processes driving paradigm shifts in science. We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur, from continuous scientific progress all the way up to scientific revolutions, which change the way we see our world. Measuring the "boosting effect" of landmark papers, our analysis reveals how new ideas and new players can make their way and finally triumph in a world dominated by established paradigms. The underlying "boost factor" is also useful to discover scientific breakthroughs and talents much earlier than through classical citation analysis, which by now has become a widespread method to measure scientific excellence, influencing scientific careers and the distribution of research funds. Our findings reveal patterns of collective social behavior, which are also interesting from an attention economics perspective. Understanding the origin of scientific authority may therefore ultimately help to explain how social influence comes about and why the value of goods depends so strongly on the attention they attract.

We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur, from continuous scientific progress all the way up to scientific revolutions, which change the way we see our world. Measuring the “boosting effect” of landmark papers, our analysis reveals how new ideas and new players can make their way and finally triumph in a world dominated by established paradigms. The underlying “boost factor” is also useful to discover scientific breakthroughs and talents much earlier than through classical citation analysis, which by now has become a widespread method to measure scientific excellence, influencing scientific careers and the distribution of research funds. Our findings reveal patterns of collective social behavior, which are also interesting from an attention economics perspective. Understanding the origin of scientific authority may therefore ultimately help to explain how social influence comes about and why the value of goods depends so strongly on the attention they attract.

  16. On the framing of patent citations and academic paper citations in reflecting knowledge linkage:A discussion of the discrepancy of their divergent value-orientations

    Institute of Scientific and Technical Information of China (English)

    LI; Rui; MENG; Liansheng

    2010-01-01

    It has been widely recognized that academic paper citations will reflect scientific knowledge linkage.Patent citations are similar to academic paper citations in many aspects:Citation frequency distribution is often skewed;citation frequency varies from one subject field to another and authors’/inventors’preference for citing relevant literature is usually confined to their own native language.However,regardless of these seemingly similarities,the patent citation is unique and special.It is constructed by incorporating information providers from multiple sources,such as from examiners,inventors,attorneys and/or the public.It is driven by a value-orientation for the monopolization of market production under regulations of Patent Laws.It is also practiced under the sway of an industrial culture embedded with a notion of"creative destruction".In view of the contextual complexities of patent citations,simply applying the data criteria and citation behavior analysis of academic paper citations to that of patentbibliometrics for the purpose of reflecting knowledge linkage is both conceptually and technically illogical and unreasonable.This paper attempts to delve into the issue of the currently misconceived assertions and practice about"transplanting"the methodology of academic paper citations en masse indiscriminately into the practice of patent citations.It is hoped that such a study would yield improved result stemming from the practice of patent citations for reflecting knowledge linkage in the future.

    Full Text Available   The present study investigate the correlation between journal citations with impact factor in the humanities scientific journals published for the 2001-2007 period based on the Persian journal citation reports generated by Islamic Science Citation (ISC database. Citation analysis method was used. Findings demonstrated that there is a significant link between impact factor and journal self-citation (r=0.606, s =0.0000. In other words, journals with low impact factors have fewer self-citations, i.e. self-citation has a positive impact on the journal impact factor. There is a negative correlation between impact factor and number of articles in humanities in the period studied. The impact factor does not increase with increase in the number of articles. There is significant correlation between the number of article published and number of self-citation. The higher the number of articles, the higher would be the number of self-citation in the journal. Findings indicated that the rate of journal self-citation in humanities had been downward for the period studied. When screening journals for self-citations, 108 journals had their ranks reduced while 204 journals had their ranking increased. The ranking in 32 journals remained unchanged.

  18. Modeling nonuniversal citation distributions: the role of scientific journals

    International Nuclear Information System (INIS)

    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)

    2015-01-01

    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

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

    Directory of Open Access Journals (Sweden)

    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.

  5. Data reuse and the open data citation advantage

    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

  3. Exploiting citation networks for large-scale author name disambiguation

    CERN Document Server

    Schulz, Christian; Petersen, Alexander M; Penner, Orion; Helbing, Dirk

    2014-01-01

    We present a novel algorithm and validation method for disambiguating author names in very large bibliographic data sets and apply it to the full Web of Science (WoS) citation index. Our algorithm relies only upon on the author and citation graphs available for the whole period covered by the WoS. A pair-wise publication similarity metric, which is based on common co-authors, self-citations, shared references and citations, is established to perform a two-step agglomerative clustering that first connects linked papers and then merges similar clusters. This parameterized model is optimized towards an h-index based recall, which favors the inclusion of well-cited publications, and a name-initials-based precision using WoS metadata and cross-referenced Google Scholar profiles. Despite the use of limited metadata, we reach a recall of 87% and a precision of 88% with a preference for researchers with high $h$-index values. 47 million articles of WoS can be disambiguated on a single machine in less than a day. We d...

This allowed us to track statistical trends in author demographics, preprint posting habits, and citation rates for ApJ papers as a whole and across various subgroups and types of ApJ papers. The most interesting results are the frequencies of use of the astro-ph server across various subdisciplines of astronomy, and the impact that such posting has on the citation history of the subsequent ApJ papers. By 2002 72% of ApJ papers were posted as astro-ph preprints, but this fraction varies from 22-95% among the subfields studied. A majority of these preprints (61%) were posted after the papers were accepted at ApJ, and 88% were posted or updated after acceptance. On average, ApJ papers posted on astro-ph are cited more than twice as often as those that are not posted on astro-ph. This difference can account for a number of other, secondary citation tren...

  15. Runaway Events Dominate the Heavy Tail of Citation Distributions

    CERN Document Server

    Golosovsky, Michael

    2013-01-01

    Statistical distributions with heavy tails are ubiquitous in natural and social phenomena. Since the entries in heavy tail have disproportional significance, the knowledge of its exact shape is very important. Citations of scientific papers form one of the best-known heavy tail distributions. Even in this case there is a considerable debate whether citation distribution follows the log-normal or power-law fit. The goal of our study is to solve this debate by measuring citation distribution for a very large and homogeneous data. We measured citation distribution for 418,438 Physics papers published in 1980-1989 and cited by 2008. While the log-normal fit deviates too strong from the data, the discrete power-law function with the exponent $\\gamma=3.15$ does better and fits 99.955% of the data. However, the extreme tail of the distribution deviates upward even from the power-law fit and exhibits a dramatic "runaway" behavior. The onset of the runaway regime is revealed macroscopically as the paper garners 1000-1...

  18. Growing complex network of citations of scientific papers -- measurements and modeling

    CERN Document Server

    Golosovsky, M

    2016-01-01

    To quantify the mechanism of a complex network growth we focus on 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 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 verification 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 non-stationary citation distributions, diverging citation trajectory of similar papers, runaways or "immortal papers" with infinite citation lifetime ...

    2005-11-01

    Full Text Available To determine the features of papers, authors, and citation of eleven journals in tropical medicine indexed by Science Citation Index Expanded, the database of the Institute for Scientific Information, we analyzed original articles, editorials, reviews, corrections, letters, biographies, and news published in these journals. The results show that these journals covered 107 countries or regions on six continents. The average number of reference was 23.05, with 87.89% of the references from periodicals. The Price Index was 31.43% and the self-citing rate was 7.02%. The references in the first 20 journals ranked by the amount of citation accounted for 36.71% of the total citations. Brazil, United States, India, and England are more advanced in tropical medicine research. The conclusion is that these journals covered most research done in these countries or regions. Most researches were done by cooperation of the researchers, but many of the publications used outdated articles and should include newer information.

  6. Influence of omitted citations on the bibliometric statistics of the major Manufacturing journals

    OpenAIRE

    Mastrogiacomo, Luca; Franceschini, Fiorenzo; Maisano, Domenico Augusto Francesco

    2015-01-01

    Bibliometrics is a relatively young and rapidly evolving discipline. Essential for this discipline are bibliometric databases and their information content concerning scientific publications and relevant citations. Databases are unfortunately affected by errors, whose main consequence is represented by omitted citations, i.e., citations that should be ascribed to a certain (cited) paper but, for some reason, are lost. This paper studies the impact of omitted citations on the bibliometric stat...

  17. Latest developments for a computer aided thermohydraulic network

    International Nuclear Information System (INIS)

    Thermohydraulic networks are I-D systems characterized by a small number of basic components (pumps, valves, heat exchangers, etc) connected by pipes and limited spatially by a defined number of boundary conditions (tanks, atmosphere, etc). The network system is simulated by the well known computer program RELAPS/mod3. Information concerning the network geometry component behaviour, initial and boundary conditions are usually supplied to the RELAPS code using an ASCII input file by means of 'input cards'. CATNET (Computer Aided Thermalhydraulic NETwork) is a graphically user interface that, under specific user guidelines which completely define its range of applicability, permits a very high level of standardization and simplification of the RELAPS/mod3 input deck development process as well as of the output processing. The characteristics of the components (pipes, valves, pumps etc), defining the network system can be entered through CATNET. The CATNET interface is provided by special functions to compute form losses in the most typical bending and branching configurations. When the input of all system components is ready, CATNET is able to generate the RELAPS/mod3 input file. Finally, by means of CATNET, the RELAPS/mod3 code can be run and its output results can be transformed to an intuitive display form. The paper presents an example of application of the CATNET interface as well as the latest developments which greatly simplified the work of the users and allowed to reduce the possibility of input errors.

  18. Trehalose Analogues: Latest Insights in Properties and Biocatalytic Production

    Directory of Open Access Journals (Sweden)

    Maarten Walmagh

    2015-06-01

    Full Text Available Trehalose (α-d-glucopyranosyl α-d-glucopyranoside is a non-reducing sugar with unique stabilizing properties due to its symmetrical, low energy structure consisting of two 1,1-anomerically bound glucose moieties. Many applications of this beneficial sugar have been reported in the novel food (nutricals, medical, pharmaceutical and cosmetic industries. Trehalose analogues, like lactotrehalose (α-d-glucopyranosyl α-d-galactopyranoside or galactotrehalose (α-d-galactopyranosyl α-d-galactopyranoside, offer similar benefits as trehalose, but show additional features such as prebiotic or low-calorie sweetener due to their resistance against hydrolysis during digestion. Unfortunately, large-scale chemical production processes for trehalose analogues are not readily available at the moment due to the lack of efficient synthesis methods. Most of the procedures reported in literature suffer from low yields, elevated costs and are far from environmentally friendly. “Greener” alternatives found in the biocatalysis field, including galactosidases, trehalose phosphorylases and TreT-type trehalose synthases are suggested as primary candidates for trehalose analogue production instead. Significant progress has been made in the last decade to turn these into highly efficient biocatalysts and to broaden the variety of useful donor and acceptor sugars. In this review, we aim to provide an overview of the latest insights and future perspectives in trehalose analogue chemistry, applications and production pathways with emphasis on biocatalysis.

  19. Latest Insights on Adenovirus Structure and Assembly

    Directory of Open Access Journals (Sweden)

    Carmen San Martín

    2012-05-01

    Full Text Available Adenovirus (AdV capsid organization is considerably complex, not only because of its large size (~950 Å and triangulation number (pseudo T = 25, but also because it contains four types of minor proteins in specialized locations modulating the quasi-equivalent icosahedral interactions. Up until 2009, only its major components (hexon, penton, and fiber had separately been described in atomic detail. Their relationships within the virion, and the location of minor coat proteins, were inferred from combining the known crystal structures with increasingly more detailed cryo-electron microscopy (cryoEM maps. There was no structural information on assembly intermediates. Later on that year, two reports described the structural differences between the mature and immature adenoviral particle, starting to shed light on the different stages of viral assembly, and giving further insights into the roles of core and minor coat proteins during morphogenesis [1,2]. Finally, in 2010, two papers describing the atomic resolution structure of the complete virion appeared [3,4]. These reports represent a veritable tour de force for two structural biology techniques: X-ray crystallography and cryoEM, as this is the largest macromolecular complex solved at high resolution by either of them. In particular, the cryoEM analysis provided an unprecedented clear picture of the complex protein networks shaping the icosahedral shell. Here I review these latest developments in the field of AdV structural studies.

  20. Latest development in codes for electromagnetic fields

    International Nuclear Information System (INIS)

    The latest development in codes for calculating electromagnetic field has concentrated on fully three-dimensional programs. Two-dimensional codes are well established and in routine use for designing accelerator equipment. However, some 2D problems are not yet solved and are still being worked on, such as determining the impedance of cylindrical objects above the cut-off frequency of the adjacent beam pipe. Three-dimensional codes are still being developed but only a few are being used. The most advanced package, the MAFIA system, has been extended recently to allow solution of electrostatic and magnetostatic fields with quasi-open boundary conditions. The modules solving for resonant frequencies and modes have been improved in their accuracy and speed. A new major revision of the whole family of codes will provide a consistent and more comfortable user interface, which is fully menu-driven with built in on-line help for all commands. This new release will also include new modules for 3D particle-in-cell simulation. Many new modules are under development and will make this system a universal tool in the design of electromagnetic devices. A user guide to the MAFIA codes with easy-to-follow instructions and examples is now available to noncommercial institutions, as is also the source code. Concurrent codes, which are not generally available, such as ARGUS or SOS, have also been improved. One can observe that the different codes become more and more alike with time. 43 refs., 6 figs., 1 tab

  1. Citation Counting, Citation Ranking, and h-Index of Human-Computer Interaction Researchers: A Comparison between Scopus and Web of Science

    CERN Document Server

    Meho, Lokman I

    2008-01-01

    This study examines the differences between Scopus and Web of Science in the citation counting, citation ranking, and h-index of 22 top human-computer interaction (HCI) researchers from EQUATOR--a large British Interdisciplinary Research Collaboration project. Results indicate that Scopus provides significantly more coverage of HCI literature than Web of Science, primarily due to coverage of relevant ACM and IEEE peer-reviewed conference proceedings. No significant differences exist between the two databases if citations in journals only are compared. Although broader coverage of the literature does not significantly alter the relative citation ranking of individual researchers, Scopus helps distinguish between the researchers in a more nuanced fashion than Web of Science in both citation counting and h-index. Scopus also generates significantly different maps of citation networks of individual scholars than those generated by Web of Science. The study also presents a comparison of h-index scores based on Goo...

  3. Structure and Dynamics of Coauthorship, Citation, and Impact within CSCW

    CERN Document Server

    Keegan, Brian; Finholt, Thomas A; Kaye, Joseph "Jofish"

    2013-01-01

    CSCW has stabilized as an interdisciplinary venue for computer, information, cognitive, and social scientists but has also undergone significant changes in its format in recent years. This paper uses methods from social network analysis and bibliometrics to re-examine the structures of CSCW a decade after its last systematic analysis. Using data from the ACM Digital Library, we analyze changes in structures of coauthorship and citation between 1986 and 2013. Statistical models reveal significant but distinct patterns between papers and authors in how brokerage and closure in these networks affects impact as measured by citations and downloads. Specifically, impact is unduly influenced by structural position, such that ideas introduced by those in the core of the CSCW community (e.g., elite researchers) are advantaged over those introduced by peripheral participants (e.g., newcomers). This finding is examined in the context of recent changes to the CSCW conference that may have the effect of upsetting the pref...

    Rankings of schools, scholars, and journals emphasize ordinal rank. Journal rankings published by Journal Citation Reports (JCR) are widely used to assess research quality, which influences important decisions by academic departments, universities, and countries. We study refereed law journal rankings by JCR, Washington and Lee Law Library (W&L), and the Australian Research Council (ARC). Both JCR’s and W&L’s multiple measures of journals can be represented by a single latent factor. Yet JCR’...

  17. Epoch making NIRS studies seen through citation trends

    International Nuclear Information System (INIS)

    Near-infrared spectroscopy (NIRS) studies through citation trends are investigated of literature concerning only the brain function measurement and its methodology together with NIRS principle, technological development, present state and future view. Investigation is conducted firstly for the survey of important author name of those concerned papers in Web of Science and Google Scholar with search words of NIRS, brain and optical topography as an option. Second, >100 papers of those authors citing any of them are picked up and their papers are ranked in accordance with Web of Science citation number, of which top-nineteen are presented here. Impact and epoch making papers are reviewed with explanations of: the establishment of measuring technology of cerebral blood flow change and subsequent brain function by NIRS; development with multi-channel detection; simultaneous measurement with other imaging modalities; examination of NIRS validity; spatial analysis of NIRS; and measurement of brain function. The highest times of citation are 1,238 of the paper by F. F. Jobsis in 'Science' (1977). It should be noted that 10 of top 19 papers are those by Japanese authors. However, review articles omitted in the present literature survey are mostly described by foreign authors: an effort to systemize the concerned fields might be required in this country. (K.T.)

  18. Universality of Performance Indicators based on Citation and Reference Counts

    Evans, T S; Kaube, B S

    2011-01-01

    We find evidence for the universality of two relative bibliometric indicators of the quality of individual scientific publications taken from different data sets. One of these is a new index that considers both citation and reference counts. We demonstrate this universality for relatively well cited publications from a single institute, grouped by year of publication and by faculty or by department. We show similar behaviour in publications submitted to the arXiv e-print archive, grouped by year of submission and by sub-archive. We also find this distribution is well fitted by a lognormal with a variance of around 1.3 which is consistent with the results of Radicchi, Fortunato, and Castellano. Our work demonstrates that comparisons can be made between publications from different disciplines and publication dates, regardless of their citation count and without expensive access to the whole world-wide citation graph. Further, it shows that averages of the logarithm of such relative bibliometric indices deal wit...

  19. Modeling nonuniversal citation distributions: the role of scientific journals

    CERN Document Server

    Yao, Zheng; Zhang, Li-Jie; Xu, Xin-Jian

    2013-01-01

    Whether a scientific paper to be cited is related not only to the influence of its author(s) but also to the journal publishing it. Scientists, either proficient or tender, usually submit their most important work to prestigious journals which receives high citations than the ordinary. Thus, scientific journals play a crucial role in citation networks. In this paper, we address this issue and develop a model for citations networks via an intrinsic nodal weight function and an intuitive ageing mechanism. In the network, each node is endowed with a weight which represents its quality determined by the journal publishing it. All the nodes have two discrete stages: active and inactive. The evolution of the network combines the addition of new active nodes randomly connected to existing active ones and the transition of old active nodes to the inactive. The node-degree distribution of resulting networks shows a nonuniversal scaling: the distribution has exponential behaviour for small degree and a power-law tail f...

  20. Citations to articles citing Benford's law: a Benford analysis

    CERN Document Server

    Mir, Tariq Ahmad

    2016-01-01

    The observation that in large data the occurrence of first significant digits of numbers is often governed by a logarithmically decreasing distribution, quite far from the ordinarily expected uniform distribution, is called Benford's law (BL). It was first reported by S. Newcomb and many decades later independently by F. Benford. Due to its counter-intuitiveness the law was ignored for decades as a mere curious observation. However, huge swell in number of publications which the law has seen lately is an indication of its remarkable resurgence. The law has come a long way, from obscurity to now being a regular subject of books, peer reviewed papers, patents, blogs and news. Here, we use Google Scholar (GS) to collect the data on the number of citations received by the articles citing the original papers of Newcomb and Benford, and then investigate whether the leading digits of this citations data are distributed according to the law they discovered. We find that the monthly citations data of the articles citi...

    Full Text Available Interrelation of models and theories of human information behaviour (HIB, their common roots, and the extent to which they are indebted to the fields other than library and information science (LIS were investigated. Fifty-one theories were selected and their bibliographic information was obtained from Web of Science and then citation analysis and bibliographic coupling analysis were performed. Pajek, HistCite, Sci2 Tool and VOSViewer software were used for analysis and visualization. The results showed that most of the theories were proposed by information scientists. A few of the theories were proposed by scientists from the fields of sociology, psychology, computer science and a few other disciplines. Citation analysis showed that LIS literature has been used extensively in HIB theories; however, there were also citations to the sources of 29 other fields especially to sociology, communication, psychology, management, educational science and computer science. This is an indication of the interdisciplinary nature of HIB domain. Bibliographic coupling map showed that about four fifths of the theories were linked to each other as a whole network. The development of a large number of theories within the field of LIS is an indication for the increasing maturity of the interdisciplinary research area of HIB as well as the maturity of LIS field.

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

    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

  4. Can Scientific Journals be Classified in terms of Aggregated Journal-Journal Citation Relations using the Journal Citation Reports?

    CERN Document Server

    Leydesdorff, Loet

    2009-01-01

    The aggregated citation relations among journals included in the Science Citation Index provide us with a huge matrix which can be analyzed in various ways. Using principal component analysis or factor analysis, the factor scores can be used as indicators of the position of the cited journals in the citing dimensions of the database. Unrotated factor scores are exact, and the extraction of principal components can be made stepwise since the principal components are independent. Rotation may be needed for the designation, but in the rotated solution a model is assumed. This assumption can be legitimated on pragmatic or theoretical grounds. Since the resulting outcomes remain sensitive to the assumptions in the model, an unambiguous classification is no longer possible in this case. However, the factor-analytic solutions allow us to test classifications against the structures contained in the database. This will be demonstrated for the delineation of a set of biochemistry journals.

    The papers in the Journal of the Korean Radiologic Society (JKRS) during recent three years were surveyed by analysis of their types, topics, organs, employed modalities, and cited literatures. Citation analysis is a method of studying interrelationships between papers and journals, and the most important application of citation analysis is in studies of science policy and research evaluation to evaluate the implementation of science policy and to monitor research performance. Using these citation analysis to map the journal communications network may indicate to more efficient scientific progress. Total number of papers published by JKRS for recent 3 years was 473 papers (Clinical : 354, Case report : 91, Experimental : 26, Educational : 2). The most common organ system of the papers was abdomen (head and neck, chest, musculoskeletal, cardiovascular, and urologic system in the order of decreasing frequency). The most popular topic was techniques including newer modalities and interventional radiology, and normal measurement, tuberculosis, hepatoma, normal anatomy and the like followed. Total number of cited references was 8,642 (18.26 per one paper), and the average number of authors per paper was 4.83. The most frequently used modality was CT (41%) followed by simple radiography, ultrasonogram, fluoroscopic study, angiography, nuclear imaging, and MRI. Using this kind of analysis as a guide for writing a paper for the JKRS, it could be well-organized and uplifted in its format and contents.

    Latest climate changes in Romania :tornadoes As climate change has been considered a research priority in the European Strategy for enduring development , I have done a detailed research with my students of the new climate change that has been going on in Romania for the past decade. More precisely I have studied together with my students the phenomenon of tornadoes that have seriously affected on some occasions some our our country's locations, such as Facaeni, in the county of Ialomita, in August 2002. A quite unusual phenomenon occurred on that location situated at 44.56 degrees northern latitude and at 27.89 degrees eastern longitude, that caused severe damage to the local environment and three persons lost their lives in the process, as well as other thirty people suffering from bad injuries. The magnitude of that strong phenomenon rose on the Fujita scale at level F3 which implied wing gusts between 252-300 km/ hour . A main cause of occurrence of such a severe weather was the difference in temperature of two huge air masses, one of Polar origin, and other coming from tropical latitudes . Their crossroads was on that precise territory of Romania. The duration of the worst part of the tornado path lasted only for two minutes, but the consequences of its passage were colossal : total destruction of 33 households, and other 395 were partially damaged, 1,000 people afflicted by the devastation and 100 acres of acacia tree forest ripped off the ground. The first ever recorded tornado phenomenon in Romania was around 1894-1896, considered at that time " a freak of nature" was seen as a cloud formation abnormality , an uncontrolled force of nature that had a huge impact , and at the same time, it vanished into "thin air " fast. The most affected areas in Romania by tornadoes are the south-eastern planes where the cloud formations can create fast columns of air rotating up to 500 km/hour. The local people compared the cloud funnels created on the planes to "serpents

  15. Counting publications and citations: Is more always better?

    CERN Document Server

    Waltman, Ludo; Wouters, Paul

    2013-01-01

    Is more always better? We address this question in the context of bibliometric indices that aim to assess the scientific impact of individual researchers by counting their number of highly cited publications. We propose a simple model in which the number of citations of a publication depends not only on the scientific impact of the publication but also on other 'random' factors. Our model indicates that more need not always be better. It turns out that the most influential researchers may have a systematically lower performance, in terms of highly cited publications, than some of their less influential colleagues. The model also suggests an improved way of counting highly cited publications.

  20. 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.

  1. Predicting long-term citation impact of articles in social and personality psychology.

    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.

  12. Co-citation Network Analysis of Religious Texts

    Science.gov (United States)

    Murai, Hajime; Tokosumi, Akifumi

    This paper introduces a method of representing in a network the thoughts of individual authors of dogmatic texts numerically and objectively by means of co-citation analysis and a method of distinguishing between the thoughts of various authors by clustering and analysis of clustered elements, generated by the clustering process. Using these methods, this paper creates and analyzes the co-citation networks for five authoritative Christian theologians through history (Augustine, Thomas Aquinas, Jean Calvin, Karl Barth, John Paul II). These analyses were able to extract the core element of Christian thought (Jn 1:14, Ph 2:6, Ph 2:7, Ph 2:8, Ga 4:4), as well as distinctions between the individual theologians in terms of their sect (Catholic or Protestant) and era (thinking about the importance of God's creation and the necessity of spreading the Gospel). By supplementing conventional literary methods in areas such as philosophy and theology, with these numerical and objective methods, it should be possible to compare the characteristics of various doctrines. The ability to numerically and objectively represent the characteristics of various thoughts opens up the possibilities of utilizing new information technology, such as web ontology and the Artificial Intelligence, in order to process information about ideological thoughts in the future.

    2013-12-01

    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.

    2013-07-01

    In the recent years, a large amount of effort has been put into the development of Silicon Photomultipliers (SiPM) as a viable technology to replace the conventional photo multiplier tubes (PMT)in many low-light level applications. In parallel, a concept has been pursued where the Geiger avalanche diodes are integrated in the same substrate with the pixel-electronics, forming arrays of Single-Photon Avalanche Diodes (SPAD) smart pixels exploiting in this way the advantages of the CMOS technology combined with single-photon counting possibilities. One of the huge problems accompanying the increase of the in-pixel circuit complexity is the unavoidable diminishing of the SPAD pixel fill-factors, which tend to descend to below 4%. Aiming at improving the SPAD front-end performance, we pursue the development of Back-Side Illuminated SPAD (BackSPAD) smart-pixel structures in the frame of the EU-FP7-ICT-5 project *MiSPiA* (grant agreement No. 257646). BackSPAD array and the smart-pixel electronics are placed one over the other in close mechanical and electrical contact. The BackSPAD detectors are isolated from each other by deep trenches. The recent measurement results of the BackSPAD structures are reported.

    Dongliang Pan; Lianchao Jin; Xianghua Zhang

    2013-01-01

    The absence of ef ective therapies for castration-resistant prostate cancer (CRPC) establishes the need to de-velop novel therapeutic modality, such as targeted gene therapy, which is ideal for the treatment of CRPC. But its application has been limited due to lack of favorable gene vector and the reduction of“bystander ef ect”. Consequently, scientists al over the world focus their main experimental research on the fol owing four aspects:targeted gene, vector, transfer means and comprehensive therapy. In this paper, we reviewed the latest advances of experimental research on targeted gene therapy for prostate cancer .

  1. Editor citation: An alleged instance of social-professional desirability

    Directory of Open Access Journals (Sweden)

    Haim Levy

    2014-01-01

    Full Text Available One of the main pillars of the academic sphere is publication of articles, the scientific purity of which should be as higher as possible. Allegedly, scientists may prefer to cite journal editors more frequently than they would do when those personae are not in editors′ position, and quite a few of the formers in quite a few instances do not seem to refuse to go along with. The viability of this sort of assertion is supported by an exploratory examination through a cross-disciplinary scanning of long-term empirical evidence from leading journals in 11 research fields. This analysis covered a total of 337 journal editors from 35 top disciplinary journals spanning 40 years. The findings seem to support the alleged trend called "editor citation". Three psychology journals appear less susceptible to such desirability. Possible accounts are suggested with a special reference to the hypothesis of moral/social modularity. [1

  2. New model for datasets citation and extraction reproducibility in VAMDC

    CERN Document Server

    Zwölf, Carlo Maria; Dubernet, Marie-Lise

    2016-01-01

    In this paper we present a new paradigm for the identification of datasets extracted from the Virtual Atomic and Molecular Data Centre (VAMDC) e-science infrastructure. Such identification includes information on the origin and version of the datasets, references associated to individual data in the datasets, as well as timestamps linked to the extraction procedure. This paradigm is described through the modifications of the language used to exchange data within the VAMDC and through the services that will implement those modifications. This new paradigm should enforce traceability of datasets, favour reproducibility of datasets extraction, and facilitate the systematic citation of the authors having originally measured and/or calculated the extracted atomic and molecular data.

    For many years, CERN has been collecting all High Energy Physics documents to make them easy to access to physics researchers. A repository of up to 170,000 electronic documents is available via the CERN Document Server [1], the main gateway to CERN's digital library. On top of the creation of this digital archive, the computing support has been looking towards possible improvements in order to ease the task of searching through and reading the articles kept. In addition to the acquisition, cataloguing and indexing of standard metadata, specific treatments have been applied to the data itself. In this paper, after a brief description of process applied to fulltext data, we shall focus on the specific work done within a collaboration between CERN, Geneva University and the University of Sunderland in order to successfully achieve the automated acquisition of structured citations from fulltext documents.

    International Nuclear Information System (INIS)

    Considering a new way of being energy system, what is required is the decision making with balances of human security, environmental safeguards, energy security, proliferation risk, economic risks and etc. After FUKUSHIMA, there are needs to provide the information for transvaluation of what nuclear energy technology is. Therefore this study focuses on nuclear energy technology. In this paper, we analyze the information about the structure and history of past and the present research papers, which aim to clarify the characteristics of research trends and issues. Our results showed overview of the structure of R and D of nuclear energy technology by citation network analysis. We found that the impacts of Chernobyl accident to basic research papers are limited and research trends seem to be influenced by national R and D budget for nuclear power but not by national fund for basic science research.

  8. Citation in Applied Linguistics: Analysis of Introduction Sections of Iranian Master's Theses

    Directory of Open Access Journals (Sweden)

    Alireza Jalilifar

    2012-01-01

    Full Text Available Writing a master's thesis, oftentimes the first shot by a novice researcher at writing for academic purposes, requires providing a framework and support by learning how to cite the works of others. Compared to the host of studies on research article introductions as the product of expert writing, little work has been done on citations in master's thesis introductions (MAIs, and so the paucity of research in this area calls for further investigation into citations in MAIs. To this aim, we compared the use of citation forms in 65 Iranian MAIs in the field of Applied Linguistics. Citation forms were divided into integral which play an overt grammatical role within a sentence and non-integral which play a covert grammatical role in text. Each category was further divided into sub-categories. Analyses of the citation practices indicated that integral citations constituted a greater proportion of citations in the MAIs. The study also examined stance manifested in verb controlling citations and underlined the importance of evidential marking in academic writing and discussed pedagogical implications of the research.

In regard to the former, in accord with the intrinsic high linear energy transfer (Let) and short path length (<100 um) of the α-particles in calcified tissue, the product is in part intended as a bone-seeking radionuclide for treatment of metastatic cancer, offering high specificity and efficacy. The Tl yield of Ge-doped SiO{sub 2} fibres has been investigated including for photonic crystal fibre un collapsed, flat fibres and single mode fibres, these systems offering many advantages over conventional passive dosimetry types. In particular, one can mention comparable and even superior sensitivity, an effective atomic number Z{sub eff} of the silica dosimetric material close to that of bone, and the glassy nature of the fibres offering the additional advantage of being able to place such dosimeters directly into liquid environments. Finally we review the use of our tailor made fibres for on-line radioluminescence measurements of radiotherapy beams. The outcome from these various lines of research is expected to inform development of doped fiber radiation dosimeters of versatile utility, ranging from clinical applications through to industrial studies and environmental evaluations.

  19. Environment and Planning B as a Journal: The interdisciplinarity of its environment and the citation impact

    CERN Document Server

    Leydesdorff, Loet

    2009-01-01

    The citation impact of Environment and Planning B can be visualized using its citation relations with journals in its environment as the links of a network. The size of the nodes is varied in correspondence to the relative citation impact in this environment. Additionally, one can correct for the effect of within-journal "self"-citations. The network can be partitioned and clustered using algorithms from social network analysis. After transposing the matrix in terms of rows and columns, the citing patterns can be mapped analogously. Citing patterns reflect the activity of the community of authors who publish in the journal, while being cited indicates reception. Environment and Planning B is cited across the interface between the social sciences and the natural sciences, but its authors cite almost exclusively from the domain of the Social Science Citation Index.

Based on many studies from abroad done in the academic environment, the citation analysis, despite its disadvantages, proved to be a valid method for the collection of indicators of real use of (library information sources. The study analysed citation patterns, characteristics of information sources used by respondents and the accessibility of these sources in the academic library. Its aim was also to test the method of citation analysis in the context of library collection evaluation. The samples used in this study were papers published in 2010 by the students and teachers of the Department of Information Sciences in Osijek. The data analysis showed that while students preferred electronic information sources, teachers preferred print sources. Also, periodicals and monographs were top two information types used in the compilation of studied publications. However, students used undefined type of web resources such as presentations and commercial and educational websites to a great extent. As far as accessibility of sources used is concerned, the results show that library offers access to 60% of periodicals used and approximately 25% of monographs. In order to minimize the limitations of this quantitative method and to obtain valid and reliable indicators of citation patterns and use of (library information sources by students and teachers at the given Department, this study should be carried out longitudinally. It should also be complemented with a qualitative study (e.g. interview with teachers and students.

    Muscle injury represents the highest proportion of sport-linked contusions. Experimental and clinical studies aim at increasingly detailed recognition of muscle physiology and pathophysiology. It would allow to set up functional standards and permit to minimize risk of contusions associated with sport activities. In cases of such contusions it would restrict its sequele and would abbreviate the duration of treatment. In the study elements of prophylaxis, treatment and rehabilitation of injured muscles will be discussed, based on current scientific results. Review study includes data from studies investigating prophylactic activities, types of teratment and the effects of different rehabilitation strategy. Latest standards from First European Congress of Football Medicine, Munich 2004, were also taken into account. The prophylactic activities should focus on education attempting to popularize the knowledge of the role of warm-up activities which precede proper physical effort, muscle stretching and activities augmenting muscle strength. The treatment of muscle injury is related to the extent of their damage. First actions should be focused on the RICE principle (Rest, Ice, Compression, Elevation). In case of torn tissues, local injections of anesthetics, anti-inflammatory agents and regeneration-promoting agents used to be applied. Application of NSAIDs and anti-thrombotic prophylaxis is sound but due to their side effects it is recommended as frequently as it is counterindicated by physicians. A threshold in the therapy, not always noted by therapeutists, involves rapid mobilization of the injured tissue. This involves mobility exercises starting at 3-5 days post-trauma, with no load at the beginning, but starting at days 4 to 6 asssociated with appropriate loading. The recently conducted studies aim at stimulation of rapid muscle regeneration, inhibition of scar formation in the site of injury and elimination of already existing scars. The latter seems most

    The h-index has been shown to increase in many cases mostly because of citations to rather old publications. This inertia can be circumvented by restricting the evaluation to a citation time window. Here I report results of an empirical study analyzing the evolution of the thus defined timed h-index in dependence on the length of the citation time window.

    This paper explores the characteristics of maps of science generated from a relatively new type of citation: web citation. The web citation data were extracted from the Chinese Science Citation Database, then were used to analyze the structure of science by applying co-classification analysis, factor analysis and visualization. The result of factor analysis is different from other studies in which the main disciplines are extracted by factor analysis. The result of factor analysis in this research shows that science research in China is application-oriented and coincides with the current national conditions. The form of map of science generated from web citation data is centric. There are four obvious characteristics in maps based on web citation data compared with maps based on other types of data:computer science is the largest node in the network of web citation;computer science is also the central node;the relationship among disciplines is more direct and the interdisciplinarity is stronger in the network of web citation;the order of main disciplines in map of science based on web citation is in accord with other maps of science, and it shows that the hardness of science has negative relation with the number of web citation.%基于一类相对较新的引文形式---网络引文绘制科学知识图谱,探讨网络引文中科学结构的特点。网络引文数据来源于中国科学引文数据库。主要采用因子分析和共类分析方法。与其他研究中因子分析能够得出主干学科领域有所不同,基于网络引文数据所得的因子分析结果体现出学科间的相互关系与当前国情的契合性,以及国内科学研究的应用性特征。网络引文中的科学结构地图属于中心型科学知识图谱,它在四个方面与其他研究中的科学结构地图存在异同:计算机科学是网络引文网络中最大的节点,同时也是中心节点;网络引文网络中学科间的

    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)

  14. 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.

  16. The Importance of Being First: Position Dependent Citation Rates on arXiv:astro-ph

    Dietrich, J P

    2007-01-01

    We study the dependence of citation counts of e-prints published on the arXiv:astro-ph server on their position in the daily astro-ph listing. Using the SPIRES literature database we reconstruct the astro-ph listings from July 2002 to December 2005 and determine citation counts for e-prints from their ADS entry. We use Zipf plots to analyze the citation distributions for each astro-ph position. We find that e-prints appearing at or near the top of the astro-ph mailings receive significantly more citations than those further down the list. This difference is significant at the 7 sigma level and on average amounts to two times more citations for papers at the top than those further down the listing. We propose three possible non-exclusive explanations for this positional citation effect and try to test them. We conclude that self-promotion by authors plays a role in the observed effect but cannot exclude that increased visibility at the top of the daily listings contributes to higher citation counts as well.

  17. A geometric graph model for citation networks of exponentially growing scientific papers

    Science.gov (United States)

    Xie, Zheng; Ouyang, Zhenzheng; Liu, Qi; Li, Jianping

    2016-08-01

    In citation networks, the content relativity of papers is a precondition of engendering citations, which is hard to model by a topological graph. A geometric graph is proposed to predict some features of the citation networks with exponentially growing papers, which addresses the precondition by using coordinates of nodes to model the research contents of papers, and geometric distances between nodes to diversities of research contents between papers. Citations between modeled papers are drawn according to a geometric rule, which addresses the precondition as well as some other factors engendering citations, namely academic influences of papers, aging of those influences, and incomplete copying of references. Instead of cumulative advantage of degree, the model illustrates that the scale-free property of modeled networks arises from the inhomogeneous academic influences of modeled papers. The model can also reproduce some other statistical features of citation networks, e.g. in- and out-assortativities, which show the model provides a suitable tool to understand some aspects of citation networks by geometry.

    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{sup 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.

    Full Text Available   The present paper examines the links between self-citation and authors’ co-incidence with impact factors of economic journals indexed in ISC. It is essentially a scientometric research employing citation analysis and literature survey. Data was collected by querying ISC and leafing through the journals studied. Self-citation, authors’ co-incidence and impact factor of the journal studied formed the variables. Correlation analysis indicated that there is a significance between authors’ self-citations and co-incidence with impact factor of the journals studied. Significance was also found between authors’ co-incidence and self-citation of the journals studied.

    We discuss microscopic mechanisms of complex network growth, with the special emphasis of how these mechanisms can be evaluated from the measurements on real networks. As an example we consider the network of citations to scientific papers. Contrary to common belief that its growth is determined by the linear preferential attachment, our microscopic measurements show that it is driven by the nonlinear autocatalytic growth. This invalidates the scale-free hypothesis for the citation network. The nonlinearity is responsible for a dramatic dynamical phase transition: while the citation lifetime of majority of papers is 6-10 years, the highly-cited papers have practically infinite lifetime.

    2008-01-01

    In this article, we analyze the citations to articles published in 11 biological and medical journals from 2003 to 2007 that employ author-choice open access models. Controlling for known explanatory predictors of citations, only 2 of the 11 journals show positive and significant open access effects. Analyzing all journals together, we report a small but significant increase in article citations of 17%. In addition, there is strong evidence to suggest that the open access advantage is declining by about 7% per year, from 32% in 2004 to 11% in 2007.

    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

    Küçüktunç, Onur; Kaya, Kamer; Çatalyürek, Ümit V

    2012-01-01

    The literature search has always been an important part of an academic research. It greatly helps to improve the quality of the research process and output, and increase the efficiency of the researchers in terms of their novel contribution to science. As the number of published papers increases every year, a manual search becomes more exhaustive even with the help of today's search engines since they are not specialized for this task. In academics, two relevant papers do not always have to share keywords, cite one another, or even be in the same field. Although a well-known paper is usually an easy pray in such a hunt, relevant papers using a different terminology, especially recent ones, are not obvious to the eye. In this work, we propose paper recommendation algorithms by using the citation information among papers. The proposed algorithms are direction aware in the sense that they can be tuned to find either recent or traditional papers. The algorithms require a set of papers as input and recommend a set...

  14. A citation analysis of Henri Tajfel's work on intergroup relations.

    Science.gov (United States)

    Dumont, Kitty; Louw, Johann

    2009-02-01

    The late Henri Tajfel (1919-1982) is one of the central figures who shaped the development of post-war European social psychology. His contributions range from the establishment of an infrastructure for a European social psychology, and the start of a new intellectual movement within social psychology, to the formulation of a set of concepts addressing intergroup relations that were finally integrated into Social Identity Theory. The present study provides an empirical examination of Tajfel's contribution to intergroup research over the last 30 years via a citation analysis of five journals: the Journal of Personality and Social Psychology, the British Journal of Social Psychology, the European Journal of Social Psychology, the South African Journal of Psychology, and the German Journal of Social Psychology (Zeitschrift für Sozialpsychologie). The results indicate that Tajfel's work on intergroup relations is increasingly cited, especially since the 1990s, and the international recognition of his work is substantial. Three possible reasons for the recognition his work still enjoys are proposed: its potential to generate theoretical and empirical controversies; its explanatory power; and the extent to which his work is used as a referential framework.

    We have tested the performance of two types of the latest Multi-Pixel Photon Counters (MPPCs; measuring 3×3 mm2 in size) developed by Hamamatsu Photonics K.K. The new S12572-050C is a successor to the S10362-33-050C (i.e., conventional 3×3-mm2 pixel MPPC of 50 μm pitch), comprises 3600 Geiger mode avalanche photodiodes (APDs), and also features high gain (up to 1.25×106), a low dark count (up to 106 cps), and improved photon detection efficiency (PDE) by up to 30%. The S12572-015C is a new type of fine-pitch (15 μm) MPPC featuring a wide dynamic range and fast timing response. This paper first presents the detailed performance of these latest MPPCs as photon counting devices. It then describes our fabrication of a prototype detector consisting of a MPPC optically coupled with a Ce:GAGG scintillator. We obtained average FWHM energy resolutions of 7.3% (15 μm) and 6.7% (new-50 μm), as compared to 6.9% (old-50 μm) for 662-keV gamma rays from the 137Cs source, as measured at 20 °C. Moreover, the number of fired pixels for 662-keV gamma rays increased by 30% for the new-50 μm (as compared to the old-50 μm). We confirmed that the low energy threshold improved from 10 keV to 4 keV, when using the latest MPPC device (new-50 μm). We also confirmed that the timing resolution of the new MPPC is 50 ps or even better, as compared to 89 ps of the old MPPC. The results thus confirm that these new types of MPPCs are promising for various applications as scintillation detectors.

    Using the Arts & Humanities Citation Index (AHCI) 2008, we apply mapping techniques previously developed for mapping journal structures in the Science and Social Science Citation Indices. Can a cognitive structure be reconstructed from the aggregated citation patterns among these 1,157 journals containing 110,718 records? Both cosine-normalization (bottom up) and factor analysis (top down) suggest a division into approximately twelve subsets. The relations among these subsets are shown using various visualization techniques. However, this structure could not be retrieved using the ISI Subject Categories, including the 25 categories which are specific to the AHCI. We discuss validation against the categories of the Humanities Indicators (of the American Academy of Arts and Sciences) and compare our results with the curriculum organization of the Humanities Section of the College of Letters and Sciences of UCLA (as an example).

  20. Implications of a single highly cited article on a journal and its citation indexes: a tale of two journals.

    Citation indexes such as journal impact factor are increasingly used to evaluate the quality of a scholarly work and/or assess one's scientific contributions. However, this simplistic approach has increasingly been refuted with publication gaming and incorrect applications to rank one's academic significance. These indexes are being game not only by researchers but also subtly by journal editors. Although the attention drawn from the public pertaining to such misbehaviors from editors is limited, the associated implications cannot be undermined. In this article, the focus will be on the motivations, impacts, and lessons learnt from how single highly cited article can have on the reactions from and the reputation of two academic journals: Folia Phoniatrica et Logopaedica and Acta Crystallographica Section A. For the former, it adopted an unconventional approach to improve its prominence in the field while the latter reiterates the correct and the original intent of citation indexes, as well as the importance of good editorial governance. From these incidents, few considerations are proposed to assist in minimising the recurrence of possible publication gaming in the editorial process. However, the inherent ethical values of an individual should still take precedence of any preventive measure. PMID:23432771
