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
Concept-level knowledge visualization for supporting self-regulated learning
No full textMastery Grids is an intelligent interface that provides access to different kinds of practice content for an introductory programming course. A distinctive feature of the interface is a parallel topic-level visualization of student progress and the progress of their peers. This contribution presents an extended version of the original system that features a finegrained visualization of student knowledge on the level of the detailed concepts that are associated with the course. The student model is based on a Bayesian-network which is built using students performance history in the learning activities. Copyright held by the owner/author(s)
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.
A Monographic Revision of the Jewel Scarabs Genus \u3ci\u3eChrysina\u3c/i\u3e from Panama, Colombia, and Ecuador (Coleoptera: Scarabaeidae: Rutelinae: Rutelini)
No full textThe work is a taxonomic revision of 28 species of the genus Chrysina Kirby (Scarabaeidae: Rutelinae: Rutelini) found in Panama (25), Colombia (2), and Ecuador (3). Chrysina tricolor (Ohaus), Chrysina chalcothea (Bates), and Chrysina cupreomarginata (F. Bates) are new records for Panama. A new country record from northern Colombia is confirmed for Chrysina mercedesae Barria. Chrysina gaitalica Curoe and Hawks and Chrysina galbina Hawks are discovered at new localities in Panama; females of both species are discovered and described. Chrysina aurora (Bates) known from other localities in the west of the country, is rediscovered in Veraguas province 147 years after its description based on a female, the only specimen that had been collected in the province. Chrysina wolfi (Ohaus) is placed as a new junior synonym of Chrysina argenteola (Bates). A neotype is designated for Chrysina ohausi (Franz) according to ICZN Article 75.3. The oreicola group is proposed to include Chrysina oreicola (Morón). Photographs of adults, illustrations of diagnostic characters, distribution maps, and taxonomic keys (in English and Spanish) for the identification of the species present in Panama, Colombia and Ecuador are presented.
El presente trabajo consiste en una revisión taxonómica de 28 especies del género Chrysina Kirby (Scarabaeidae: Rutelinae: Rutelini), 25 presentes en Panamá, 2 en Colombia y 3 en Ecuador. Chrysina tricolor (Ohaus), Chrysina chalcothea (Bates) y Chrysina cupreomarginata (F. Bates) son nuevos registros para Panamá. Se confirma un nuevo registro del norte de Colombia correspondientes a Chrysina mercedesae Barria. Chrysina gaitalica Curoe y Hawks y Chrysina galbina Hawks se descubren en nuevas localidades de Panamá; se descubren y describen hembras de ambas especies. Chrysina aurora (Bates) conocida en otras localidades del oeste del país, es redescubierta en la provincia de Veraguas después de 147 años desde su descripción a partir de una hembra, único ejemplar que había sido recolectado en la provincia. Chrysina wolfi (Ohaus) se considera una nueva sinonimia menor de Chrysina argenteola (Bates). Se asigna un neotipo a Chrysina ohausi (Franz) por aplicación del artículo 75.3 del CINZ. Se propone el grupo oreicola para incluir a Chrysina oreicola (Morón). Se presentan fotografías de adultos, ilustraciones de caracteres diagnósticos, mapas de distribución y claves taxonómicas (en Inglés y Español) para la identificación de las especies presentes en Panamá, Colombia y Ecuador.

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
Designing Criminal Tribunals: Sovereignty and International Concerns in the Protection of Human Rights, by Steven D. Roper and Lilian A. Barria
No full textSteven D. Roper and Lilian A. Barria, professors in the Department of Political Science at Eastern Illinois University, are frequent collaborators on scholarly work concerning criminal tribunals. Their co-authored articles and joint conference presentations on assorted aspects of this topic have culminated in Designing Criminal Tribunals, a book that examines various ad hoc tribunals, primarily those created since the end of the Cold War. These tribunals include the United Nations International Criminal Tribunals for the Former Yugoslavia (ICTY) and Rwanda (ICTR), both international tribunals; the Special Court for Sierra Leone (SCSL), the Extraordinary Chambers in the Courts of Cambodia (ECCC), and the Special Crimes Panel for East Timor (SCPET), all mixed tribunals; and the Indonesian Human Rights Court (IHRC), a purely domestic court
