Raggophyllum species distribution is restricted to Inambari, the second larger Amazonian area of endemism, comprising 1.327.00 km², limited to the north by the Amazon river, to the south by the Madeira river and southwest by the Andes mountain range (Da Silva et al., 2005) (Fig. 13). Information on invertebrate groups associated with this area is scarce. Thus, this is the first study that associates a group of katydids with this region.Published as part of Mendes, Diego Matheus De Mello & Rafael, José Albertino, 2021, Redescription of Raggophyllum Nickle, 1967 (Orthoptera: Tettigoniidae: Phaneropterinae) with description of a new species from Brazilian Amazon Rainforest and placement in Microcentrini Brunner von Wattenwyl, 1878, pp. 547-560 in Zootaxa 4950 (3) on pages 548-549, DOI: 10.11646/zootaxa.4950.3.7, http://zenodo.org/record/465011
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 specimens from Brazil (Acre) were collected in a terra firme upland forest with high bamboo density (Guadua sp.), locally called “taboca”. As discussed by Mendes & Rafael (2020) for Acropsis tectiformis (Brunner von Wattenwyl, 1878), possibly R. spinosum distribution is associated with Amazonian bamboo forests from the foot of the Andes (Peru and part of Bolivia) to the Brazilian Amazon.Published as part of Mendes, Diego Matheus De Mello & Rafael, José Albertino, 2021, Redescription of Raggophyllum Nickle, 1967 (Orthoptera: Tettigoniidae: Phaneropterinae) with description of a new species from Brazilian Amazon Rainforest and placement in Microcentrini Brunner von Wattenwyl, 1878, pp. 547-560 in Zootaxa 4950 (3) on pages 549-554, DOI: 10.11646/zootaxa.4950.3.7, http://zenodo.org/record/465011
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

The R&D Tax Incentives
No full textThis article sets out some background information and reflections of the author on the R&D tax incentive schemes included in the Common Corporate Tax Base (CCTB) Proposal. In particular the author analyzes the stimulus to private R&D through ad hoc tax incentives included in the CCTB Proposal and dives into the actual provisions included in the Proposal highlighting the most relevant issues connected with their design and interpretation. Moreover, the author explores the interaction between the CCTB Proposal and the granting by Member States of domestic R&D tax incentives
