“Don Juan in the Ottoman East: Dis/continuities in Cantos V-VIII”
No full textAs with the English cantos, those set in Constantinople and Ismail constitute a discrete narrative sequence within Don Juan, one whose apparently seamless plot progression is criss-crossed by continuities and discontinuities in relation to the poem’s previous instalments. Discontinuities particularly concern the position of these cantos in the poem’s compositional history during the fraught period of 1821-22, as well as a representation of the Ottoman East which knowingly reprises and relentlessly subverts familiar orientalist topoi. In keeping with Don Juan’s pervasive medley mode, cantos V-VIII are built on an interplay of dis/continuities forcing readers uninterruptedly to identify and decode multiple, ever-varying lines of argument about excess, consumption, eroticism and war, and held together by a central thread of reflections on power. Investigating the thematic and structural peculiarities of this section of Don Juan, this chapter suggests that we read it as a unit within the poem, which consistently engages questions of authority and control through a distinctive interweaving of figurative protocols, historical-ideological materials, and metaliterary references
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
"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.
Simulations of large winds and wind shears induced by gravity wave breaking in the mesosphere and lower thermosphere (MLT) region
No full textUsing a fully nonlinear two-dimensional (2-D) numerical model, we simulated
gravity waves (GWs) breaking and their contributions to the formation of
large winds and wind shears in the mesosphere and lower thermosphere (MLT).
An eddy diffusion coefficient is used in the 2-D numerical model to
parameterize realistic turbulent mixing. Our study shows that the momentum
deposited by breaking GWs accelerates the mean wind. The resultant large
background wind increases the GW's apparent horizontal phase velocity and
decreases the GW's intrinsic frequency and vertical wavelength. Both the
accelerated mean wind and the decreased GW vertical wavelength contribute to
the enhancement of wind shears. This, in turn, creates a background condition
that favors the occurrence of GW instability, breaking, and momentum
deposition, as well as mean wind acceleration, which further enhances the
wind shears. We find that GWs with longer vertical wavelengths and faster
horizontal phase velocity can induce larger winds, but they may not
necessarily induce larger wind shears. In addition, the background
temperature can affect the time and height of GW breaking, thus causing
accelerated mean winds and wind shears
Shears band with a large dynamic moment of inertia in
No full textHigh-spin states in 197Bi were studied with the AFRODITE γ-ray array at iThemba LABS using the 181Ta( 22Ne, 6n) reaction at a beam energy of 125 MeV. A new shears band was found and linked to the low-lying states in 197Bi. Its dynamic moment of inertia, , is considerably larger than the of the shears bands in the neighbouring Pb isotopes. This is probably a result of the involvement of an additional high-K

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
