Systematics of the neotropical butterfly genus paryphthimoides forster, 1964 (lepidoptera: nymphalidae: satyrinae), with descriptions of seven new taxa
No full textA systematic revision of Paryphthimoides, a satyrine genus widely distributed in Central and South America, is presented based on an integrative approach. Molecular phylogeny inferred using multiple methods with nuclear (GAPDH, RpS5) and mitochondrial (COI) genes indicates that Paryphthimoides, as currently circumscribed, is polyphyletic. A new taxonomic arrangement is proposed reflecting the monophyly based on molecular and morphological evidence. Paryphthimoides now comprises 14 taxa, namely: P. poltys poltys (), P. poltys numilia (C. Felder & R. Felder, 1867) stat. nov., P. vestigiata (Butler, 1867), P. fridae Zacca, Casagrande, Huertas & Nakahara sp. nov., P. jorupe Zacca, Casagrande, Checa & Willmott sp. nov., P. terrestris terrestris (Butler, 1867) comb. nov., P. terrestris muyrakytan Zacca, Casagrande & Mielke ssp. nov., P. terrestris araguaianus Zacca, Casagrande & Mielke ssp. nov., P. terrestris grevei Zacca, Casagrande & Mielke ssp. nov., P. touloulou () comb. nov., P. brixius brixius () comb. nov., P. brixius madre Zacca, Mielke, Casagrande & Lamas ssp. nov., P. brixius rouranensis Brévignon ssp. nov. and P. flavofascia (Zacca & Siewert, 2014) comb. nov. Euptychia zeredatha and P. bahneri are new synonyms of P. p. poltys, and Euptychia binalinea Butler, 1867 and E. poltys bahiana are new synonyms of P. poltys numilia. Lectotypes are designated for Euptychia zeredatha, Neonympha numilia, Euptychia vestigiata, Euptychia terrestris and Euptychia brixiola, Butler, 1867 and a neotype is designated for Satyrus brixius. In addition, female morphology is described for the first time for all available species, and biological data and distributional maps are provided for all species. Last instar and pupae of Paryphthimoides p. poltys are also described

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"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.

No full text[ES] Uno de los problemas de la sociedad española actual es la despoblación que sufre su territorio así como la falta de oportunidades que tiene la población que se resiste a abandonarlo. Es por ello que surge la inquietud por tratar el tema del éxodo rural en España y más concretamente en un pequeño pueblo de Guadalajara, Checa.
La población actual del municipio, como en muchos otros con la misma problemática, es una población envejecida que contrasta con la población joven que quiere seguir viviendo en su lugar de origen. Por ello mismo, se pretende la creación de un proyecto que fomente el flujo de migración desde las zonas urbanas masificadas hacia entornos rurales castigados por la falta de población, pero sobre todo, dotar de oportunidades a dicha población joven para que pueda formarse académicamente en su propio pueblo.[EN] One of the problems of current Spanish society is the depopulation that its territory suffers as well as the lack of opportunities for the population that refuses to abandon it. That is why the concern arises to address the issue of rural depopulation in Spain and more specifically in a small village in Guadalajara, Checa.
The current population of the village, as in many others with the same problem, is an aged population that contrasts with the young population that wants to continue living in its place of origin. For this reason, the creation of a project that fosters the migration flow from overcrowded urban areas to rural environments punished by the lack of population is sought, but above all, provide opportunities to said young population so that they can learn in their own village.Asensio Lozano, R.

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

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
Periostracal mineralization in the gastrochaenid bivalve Spengleria
No full textWe investigated the spikes on the outer shell surface of the endolithic gastrochaenid bivalve genus Spengleria with a view to understand the mechanism by which they form and evaluate their homology with spikes in other heterodont and palaeoheterodont bivalves. We discovered that spike formation varied in mechanism between different parts of the valve. In the posterior region, spikes form within the translucent layer of the periostracum but separated from the calcareous part of the shell. By contrast those spikes in the anterior and ventral region, despite also forming within the translucent periostracal layer, become incorporated into the outer shell layer. Spikes in the posterior area of Spengleria mytiloides form only on the outer surface of the periostracum and are therefore, not encased in periostracal material. Despite differences in construction between these gastrochaenid spikes and those of other heterodont and palaeoheterodont bivalves, all involve calcification of the inner translucent periostracal layer which may indicate a deeper homology
