No full textMeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
JADE, a new software tool for nuclear fusion data libraries verification & validation
No full textNuclear data improvement is a key objective in the nuclear field and, in particular, for fusion application. Due to their complex production process, new nuclear library releases must undergo systematic and extensive Verification and Validation (V&V) procedures. A novel software tool, JADE, is presented in this work. Its aim is to lead the path to a full standardization and automatization of V&V processes for neutron-gamma Monte Carlo transport for fusion applications, as well as saving substantial user time and avoid error-prone editing operations. JADE is a Python 3 based software that will be able to automatically run and post-process an exhaustive suite of computational and experimental benchmarks, together with the incorporation of pre-existing quality checks strategies. A first computational benchmark, the Leakage Sphere benchmark, has been implemented, a series of nuclear libraries were tested with it and the results have been discussed. The capability of JADE for spotting anomalies in the cross sections has been conclusively proven by being able to highlight inconsistencies already documented in the related literature. Moreover, some previously unknown anomalies have been identified and discussed, giving evidence of JADE's applicability for the validation of future nuclear libraries releases. Finally, future developments and objectives are discussed
Application of JADE V&V capabilities to the new FENDL v3.2 beta release
No full textFENDL nuclear data libraries are planned to be adjourned soon with a new release (v3.2). A beta version, together with previous FENDL releases and the ENDF/B-VIII.0, have been tested on the sphere leakage and ITER 1D computational benchmarks using JADE, a new and under development verification and validation (V and V) tool. The consistency checks performed on the new FENDL v3.2 beta release did not spot any formal inconsistency and the comparison of the results show that, in general, the new FENDLv3.2 beta behaviour is quite similar to the FENDL v3.1d one. Nevertheless, a few significant differences with respect to the previous FENDL version and to the ENDF/B-VIII.0 results have been highlighted by the tool and discussed in the paper. The work proves how JADE has the potential to become an important player in the V and V procedures of nuclear data libraries
