On a result by Clunie and Sheil-Small
No full textIn 1984 J. Clunie and T. Sheil-Small proved ([2, Corollary 5.8]) that for any complex-valued and sense-preserving injective harmonic mapping in the unit disk , if is a convex domain, then the inequality |G(z_2)-G(z_1)| < |H(z_2)- H(z_1)| holds for all distinct points . Here and are holomorphic mappings in determined by , up to a constant function. We extend this inequality by replacing the unit disk by an arbitrary nonempty domain in and improve it provided is additionally a quasiconformal mapping in

MeSH 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
“Staging the Last Stand: The Politics of Aben Humeya in Richard Lalor Sheil and Francisco Martínez de la Rosa”
No full textDealing with an Irish and a Spanish playwright and two dramas staged thirteen years apart in London and Paris respectively, this essay experiments with a comparative reading of parallel texts in order to gauge its potential for insights in the context of Romantic-era Anglo-Hispanic studies. The two authors—Richard Lalor Sheil and Francisco Martínez de la Rosa—were representatives of a political and literary-cultural liberal internationale in the post-Waterloo years. Their plays on Aben Humeya, the leader of the morisco rebellion of 1568–71 (The Apostate, 1817, and Aben Humeya, o la rebelión de los moriscos, 1830), proceed from this ideological background and trans- national web of cultural exchanges and literary developments. While examining the parallels and divergences in their treatments of this material, this essay also provides further evidence of how the Spanish-Moorish imaginary constituted a powerful clus- ter of thematic and ideological faultlines crossing European literatures between the eighteenth and nineteenth centuries, a rich quarry of stories and histories associated with ‘hot chronologies’ (most notably, the conquest of Granada in 1492) and available for allusive, coded inscriptions of current concerns
"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
