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.

PANGAEA, https://doi.org/10.1594/PANGAEA.983803Pyrosomes are colonial tunicates that inhabit diverse environments and perform diel vertical migrations, contributing to the downward carbon flux primarily through large fecal pellet production and carcass depositions. Pyrosoma atlanticum is the most widespread pelagic colonial tunicate worldwide, yet its role in the carbon cycle remains poorly understood. Here, we investigated the abundance, biomass, and contribution of P. atlanticum colonies to the biological carbon pump using MOCNESS and Mesopelagos nets in the subtropical waters off the Northwest African upwelling transition zone. We found two different areas within the studied zone: a highly productive area off the African coast and an oligotrophic area. We only found P. atlanticum near and in the productive area. Organisms sampled with the MOCNESS showed a narrower size distribution (colony length of 23.1 ± 12.4 mm) associated with the lower productivity area. By contrast, the Mesopelagos captured a wider size community (colony length of 106.5 ± 74.5 mm). Off the African coast, migrant biomass of small-sized organisms exhibited values almost 2-fold higher compared to the large-sized organisms (121 vs 77.1 mgC·m−2). In oligotrophic waters, where only small-sized organisms were captured, their migrant biomass reached values four times higher (493 mgC·m−2). Two approaches were used to estimate large-sized pyrosomes active flux: (1) the enzymatic activity of the electron transfer system (ETS) and (2) a specific respiration equation (RC) for P. atlanticum. In the productive area, both methods yielded similar values for large-sized organisms (ETS: 2.02 mgC·m−2·d–1 and RC: 1.93 mgC·m−2·d–1). Small-sized organisms were quite abundant in the oligotrophic station showing a RC of 3.03 mgC·m−2·d–1. Active flux by P. atlanticum ranged between 1.93 near the upwelling zone and 12.36 mgC·m−2·d–1 in oligotrophic waters due to their quite high biomass there. Our finding highlights the functional role of this large zooplanktonic and micronektonic fauna in the biological carbon export according to the productivity of the area.We would like to thank the captain and crew of the R/V Sarmiento de Gamboa their support and hard work during the cruise.

No full textDispelling 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

Intervenció de caràcter conservatiu d un donjunt d ossos fòssils d un saurópode titanosaure.
No full text[ES] Los restos paleontológicos tienen una gran relevancia a nivel científico e incluso cultural, ya que son evidencias de la vida en épocas pasadas que ayudan a comprender cómo era el mundo en aquellos tiempos remotos. Es por ello que la intervención conservativa de dichos restos fósiles es fundamental para garantizar su perdurabilidad en el tiempo, facilitando su estudio y garantizando su conservación durante su posterior almacenaje, estudio o exhibición. En este Trabajo Final de Máster se documenta el proceso de intervención conservativa llevado a cabo sobre un conjunto de restos fósiles de un espécimen de saurópododo titanosaurio de finales del Cretácico. Este trabajo aborda, por tanto, las diferentes fases de la intervención del espécimen, desde su liberación del sistema de extracción in situ, pasando por su limpieza y consolidación, hasta el montaje de los fragmentos que lo permitan. Asimismo, se llevará a cabo un estudio sobre los diferentes estucos sintéticos para la reintegración volumétrica, con el fin de elaborar un mortero de reintegración que cumpla con los requisitos de idoneidad para este conjunto de fósiles.[EN] Paleontological remains have an extensive scientific and cultural relevance, because they are the evidence of life during past eras and they help us to understand how the world was at those remote times. Therefore, the conservative intervention on the fossil remains is essential to ensure their durability and to make possible their study, and it's also a way of guaranteeing their preservation during posterior storage, studies or exhibitions. This Master's Degree Final Project documents the processes of conservative intervention applied on a set of fossil remains belonging to a specimen of sauropod titanosaur from the Late Cretaceous. Consequently, this work addresses the different phases of the specimen¿s intervention, from the removal of the extraction system used in situ, continuing with the cleaning and consolidation, to the mounting of the fragments as long as possible. Furthermore, looking deeper into the last phase, a study of the different synthetic stuccos for volumetric reintegration will be performed, in order to develop a reintegration mortar which fulfills the requirement of suitability for this set of fossils.Silvestre Lezcano, I.
