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

Colômbia e o tráfico internacional de drogas: a securitização do tema nos governos de Álvaro Uribe e Manuel Santos
No full textTCC (graduação) - Universidade Federal de Santa Catarina. Centro Sócio-Econômico. Relações Internacionais.O estudo visa analisar a postura do governo Santos (2010-2014) em relação ao narcotráfico como tema da agenda de segurança internacional, utilizando conceitos da Escola de Copenhague. A análise é feita pela contextualização do narcotráfico na Colômbia, e da análise das políticas antidrogas no governo Uribe (2002-2010) e no governo Santos (2010-2014). Também se observa a influência norte-americana nas políticas de combate ao narcotráfico e as relações da Colômbia com os países vizinhos em relação ao tema. No governo Uribe, percebe-se a securitização do narcoterrorismo, alinhado com as ideias norte-americanas, por meio de políticas enérgicas de militarização, fortalecimento da Força Pública, erradicação dos cultivos por aspersão aérea, e desrespeito aos direitos humanos. No governo Santos, o tráfico de drogas continuou securitizado, entretanto, pode-se notar o distensionamento da forma como é tratado, com adoção de iniciativas mais brandas

The specimen photographed by Martin Reith (Fig. 4A) has a complete orbital band, different from the dorsally interrupted band of the female specimens reported by Santos (2016). Fore wing. Santos (2016) reports “H1WC” (actually, HW1C) = 1.0, but a direct measurement in figure 7 in that work returns HW1C = 1.10. Material examined. Photos of two females in their natural habitat. DOMINICAN REPUBLIC: Hispaniola, 18°01’15.6”N, 71°08’34.8”W, 01.V.2015, 15:42 h, photographed by Martin Reith (Fig. 4); Unknown location and date, photographed by Dennise Morales Pou (https://flickr.com/photos/59050296@N08/25207328276/in/photostream/). The first specimen is a new geographic record for the species. Comments. The availability of multiple photographic records online suggest that N. laluzbrillante might be a common species in the Dominican Republic, in the same way that N. ornatipennis is abundant and widespread in Cuba.Published as part of Supeleto, Fernanda A., Aguiar, Alexandre P. & Santos, Bernardo F., 2021, A new species, key and further redefinition of Nesolinoceras Ashmead (Hymenoptera, Ichneumonidae, Cryptinae), pp. 107-116 in Zootaxa 5016 (1) on page 115, DOI: 10.11646/zootaxa.5016.1.
Schmidarius kondratieffi Santos-Silva, Heffern, Botero & Nascimento 2020
No full textSchmidarius kondratieffi Santos-Silva, Heffern, Botero & Nascimento, 2020 Figures 35–36 Schmidarius kondratieffi Santos-Silva et al., 2020: 6; Monné, 2022b: 743 (cat.). Schmidarius kondratieffi was described based on a single female from Mexico (Mexico). We have examined two additional females, which allows us to establish new state records and point out some morphological variations. These specimens differ from the holotype (see photographs on Bezark 2022) by the antennomere III slightly slender, sinuous, and less densely setose (Figs. 35–36), and the mesoventral process has no distinct extension on each side near the apex (not projected on the mesocoxae) (Fig. 36). As the other morphological features perfectly agree with those of the holotype, we believe that they are intraspecific variations. Material examined. MEXICO, Jalisco (new state record): Nevado de Colima Road, 7 mi. W hwy. junct. (near Atenquique), 1 female, 5.VIII.1978, Plitt & Schaffner leg. (FSCA).

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

Halichondria (Halichondria) marianae sp. nov. differs from other Tropical Western Atlantic species by its combination of long and robust oxeas (large than 500 µm) and dark green color. External morphology (Fig. 2A–D). Thickly encrusting to massive sponges. The preserved holotype consist of one fragment, one 9.5 x 2.5 x 3 cm (length x width x thickness). Surface rugose and rough. Regularly oscular projections or diffusely distributed along the top of the sponge (Fig. 2A – D) less than 4 mm in diameter, generally in rows, some with membranous rims slightly down. Some specimens with subectosomal thin canals ending in oscula. Texture firm, soft, fleshy, but compact and compressible. Color in vivo is dark green (externally) and greenish (internally), becoming grayish or brownish after fixation (ethanol 92 %). Skeleton (Fig. 2E–F). Ectosome detachable from choanosome. The ectosomal skeleton is typically composed of a regular reticulation of tangentially arranged tracts (40–90 µm in diameter) of oxeas (Fig. 2E). Choanosomal skeleton is typically halichondrid (Fig. 2F), with oxeas of variable length organized in a confused fashion, showing a tendency to form ascending tracts (30–160 µm in diameter). Tracts form small brushes of oxeas perpendicular in the surface (see Fig. 2F). Many loose interstitial spicules in the basal and deeper regions. Pigmented cells in both regions and little spongin present. Spicules (Fig. 3A–B, Table 1 and 2). Oxeas smooth, varying from straight to slightly curved, not divisible into two categories (90– 340.4 –800 / 5– 11 –20 µm). Ecology. This species is often found in reef environments in sciaphylous habitats (Fig. 2C). Shallow water at 0.5–1 m depth. Distribution (Fig. 1). Brazil: Northeastern Region: Paraíba and Bahia State. Etymology. Named after Mariana Carvalho, researcher from Museu Nacional, Universidade Federal do Rio de Janeiro, to her contributions to the knowledge of Brazilian sponges. Remarks. Halichondria (Halichondria) marianae sp. nov. differs from the other 13 species recorded for the Tropical Western Atlantic by its combination of long and robust oxeas and dark green color. The most similar species is Halichondria (H.) melanadocia de Laubenfels, 1936 from Florida due to the detachable ectosome, choanosomal with spicules strewn in confusion and fusiform oxeas. However, both species clearly differ in the size of the oxeas, whereas in new species is larger than Halichondria (H.) melanadocia (Table 2). Additionally Halichondria (H.) melanadocia have a black color whereas the new species is green (see Table 2). Another Tropical Western Atlantic Halichondria species is Halichondria (Halichondria) corrugata Diaz, van Soest & Pomponi, 1993, but it has smaller and thinner spicules than new species (Table 2). Additionally, Halichondria (H.) corrugata also present color light greenish-brown or pink and lobate growth form against dark green color and thickly encrusting to massive form in the new species. Halichondria (Halichondria) lutea Alcolado, 1984 differ from new species in many features: the oxeas are larger than in new species and the growth form is subspherical. Finally, H. (H.) lutea is orange to yellow alive with corrugated projections against dark green color with surface rugose in Halichondria (H.) marianae sp. nov. Halichondria (Halichondria) stylata Diaz, Pomponi & Van Soest, 1993 have oxea, styles and styloids differs from the present specimen by possessing smaller spicules (see Table 2). Furthermore, the possession of color black and of styles separate if from the Halichondria (H.) marianae sp. nov. References: (1) Carvalho & Hajdu (2001); (2) Diaz et al. (1993); (3) Alcolado (1984); (4) Hechtel (1965); (5) de Laubenfels (1936). In Brazil, five species of Halichondria had been reported (Table 2) and many other specimens are available in scientific collections without identification at specific level (Muricy et al. 2011). Among the species recorded for the Brazilian coast, Halichondria (H.) tenebrica is the most similar to Halichondria (H.) marianae sp. nov. in the spicules size and shape (see Table 2). The new species differs from Halichondria (H.) tenebrica in the ectosomal skeleton and color: Halichondria (H.) marianae sp. nov. presents ectosomal skeleton with a regular reticulation of tangentially arranged always multispicular tracts of spicules (40–90 µm in diameter) and with abundant pigmented cells in both regions against ectosomal skeleton with a dense tangential reticulation of pauci-multispicular tracts (30–140 µm in diameter) of Halichondria (H.) tenebrica. Finally, Halichondria (H.) tenebrica do not exhibit pigmented cells and may display the color purple in vivo and in ethanol. However, this color has not been observed in any of the specimens described herein. Halichondria (H.) marianae sp. nov. differs from all other four species recorded from Brazil (Halichondria (H.) cebimarensis; Halichondria (H.) magniconulosa; Halichondria (H.) migottea and H. (H.) sulfurea) due to the combine of long and robust oxeas and the presence of dark green color (see Table 2). This description of Halichondria (Halichondria) marianae sp. nov. increased to 17 the number of Halichondria (Halichondria) for the Tropical Western Atlantic (Muricy 2017).Published as part of Santos, George Garcia, Nascimento, Elielton & Pinheiro, Ulisses, 2018, Halichondriidae Gray, 1867 from the Northeastern Brazil with description of a new species, pp. 556-566 in Zootaxa 4379 (4) on pages 558-562, DOI: 10.11646/zootaxa.4379.4.7, http://zenodo.org/record/117509
