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
The Dynamic Effects of Open-Space Conservation Policies on Residential Development Density
No full textRecent economic analyses emphasize that designated open-space increases the rents on neighboring residential land, and likewise, the probability of undeveloped land converting to residential uses. This paper addresses a different question: What is the effect of local open space conservation on the rate of growth in the density of existing residential land? The analysis is relevant for exurban development and also for remote lakeshore development, where shoreline development density can rapidly increase over time and open-space policies are often advocated as a way to protect ecosystems by reducing development. A discrete choice econometric model of lakeshore development is estimated with a unique parcel-level spatial-temporal dataset, using maximum simulated likelihood to account for i) the panel structure of the data, ii) unobserved spatial heterogeneity, and iii) sample selection resulting from correlated unobservables. Results indicate that, contrary to the intuition derived from the current literature, local open space conservation policies do not increase the rate of growth in residential development density, and some open space conservation policies may reduce the rate of growth in residential development density. This is consistent with land-value complementarity between local open space and parcel size. Spatially-explicit simulations at the landscape scale examine the relative effects of conservation policies on the time path of development.
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

Montréal Télégraphe : Le son iconographe = Montreal Telegraph : Sound as Iconographer
No full textThis CD-ROM and audio CD document installations and sound performances by J.P. Gauthier, R. Gervais and J. Heward, presented as part of the “Sound as Iconographer” exhibition (2000). The CD-ROM contains an introductory essay by the artist-curators (Provencher and Tremblay) that suggests the multidisciplinary works in the exhibition explore relations between art and science, material aspects of sound and the musical potential of objects. It also includes information on the artists, detailed documentation of their works (incorporating electro-acoustic, electronic and improvisational music), comprehensive information on influential artists/composers (Cage, Duchamp, Varèse, Russolo, Satie, Rauschenberg) and inventors of technology (Bell, Berliner, Cros, Edison, Fessenden, Marconi, Morse); and a link to the Montréal Télégraphe website. The audio CD presents: five musical compositions by J.P. Gauthier and M. Sabatini; four pieces by R. Gervais, R.M. Lepage and M. Goldstein; and one composition by J. Heward, M. Goldstein, D. Prentice and R. Wiens. 71 bibl. ref. 80 disc. ref
