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 mechanisms of building a post-acute care network: navigating the care continuum
No full textHealthcare continues to rapidly evolve from a simplistic fee-for-service model to that of healthcare system management of a population. Healthcare management models that seek to advance public health include the requirement that an episode of care comprehensively also incorporate the post-acute care placement, management, and costs. Historically, post-acute care has been managed by independent providers. However, in an era of bundled payment and responsibility for the entire episode of care being transferred to a hospital-based health care network, it is now imperative that health care systems develop a partnership on some level with their post-acute care providers. Currently the public health is served by primarily independent post-acute care providers that are often expensive and rarely coordinate with the providers that refer patients to them. The impact of this is that a high cost post-acute care episode is driven by an individual institution seeking to maximizing revenue with a sole focus on the post-acute care issues and with little knowledge of the overall long term needs of the individual patient. This uncoordinated system has a meaningful negative impact on the value of care provided. Ultimately with respect to the population there is a consequential public health impact that offers a significant opportunity for improvement
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
Identifying empirically supported treatments: What if we didn’t
No full textThe conclusion of the Division 12 Task Force's report on empirically supported treatments raises 3 questions: (a) Is it desirable for the profession to specify what treatments are effective? (b) Do the criteria, either selected by the Task Force or modified by others, represent a reasonable way of identifying effective treatments? (c) Would different and less controversial conclusions have been reached if the criteria used were broadened to include naturalistic and quasi-experimental studies? It is concluded that the Task Force's selection of criteria, particularly as modified by D. L. Chambless and S. D. Hollon (1998) , was a reasonable response to these pressures. Findings from studies using less stringent and controlled research designs suggest that the proposals may have resulted in less palatable conclusions than those offered in its original report.

"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
