Testudo chernovi Khosatzky 1948
<i>Testudo chernovi</i> Khosatzky, 1948 <p>Material. Nuchals, NMNHU-P AR 406 (FIg. 2, G), AR 407 (FIg. 3, A).</p> <p>Description. The anterior edge of the bones is slightly notched. The cervical scute is narrow, arrow-shaped and wedged on the inner side; its length reaches 11.0 mm. Lateral wings of the nuchal plate are not covered with pleural scutes. The midline length of the specimens AR 406 and AR 407 is equal to 31.6 and 36.1 mm, the greatest width — 38.0 and 46.2 mm, respectively. The length to width ratio is 0.83 (AR 406) and 0.78 (AR 407).</p> <p> Remarks. The specimens are identical in morphology and shape to those of <i>T. chernovi</i> from the Early Pliocene of Ukraine (Khosatzky, 1948 a), although they are smaller and possess a shorter cervical scute. The nuchal of the closely related species <i>Testudo kuchurganica</i> Khosatzky, 1948 has a straight anterior edge and its lateral wings are covered with pleural scutes.</p> <p>A series of characteristic scratches has been observed on one of the specimens considered (fig. 3, B–C). It was interpreted as traces of gnawing or rasping (Mikuláš et al., 2006) and described as a new ichnospecies below.</p>Published as part of <i>Yanenko, V. & Kovalchuk, О., 2023, Late Miocene Turtles Of Grytsiv (Western Ukraine) With Rodent Gnaw Marks On The Carapace Surface, pp. 311-322 in Zoodiversity 57 (4)</i> on page 315, DOI: 10.15407/zoo2023.04.311, <a href="http://zenodo.org/record/10831776">http://zenodo.org/record/10831776</a>
Melanochelys moldavica Chkhikvadze 1983
<i>Melanochelys</i> cf. <i>moldavica</i> <p>M a t e r i a l. One right xiphiplastron NMNHU-P AR 405 (FIg. 2, D–E), one neural plate AR 404, one costal plate AR 403 (FIg. 2, C).</p> <p>Description. The posterior lobe of the right xiphiplastron is smoothly narrowed. The femoro-anal notch is weakly expressed. The short xiphiplastral processes are rounded and not bent posteriorly. The moderate anal notch is pointed. The transverse ridge on the upper surface of the caudal part of the xiphiplastron is moderately developed, and it is almost parallel to the posterior edge of the bone. The neural plate is wide, hexagonal, with a distinct bend of the medial keel. The fragments of costal plates are uniform in width.</p> <p> Remarks. The right xiphiplastron from Grytsiv is morphologically similar to that in <i>Melanochelys moldavica</i> from the middle Sarmatian of Moldova (Chkhikvadze, 1983) except for the more pronounced transverse ridge on the upper surface of its caudal part. It further differs from the respective bones of the other geoemydid turtles (e. g., <i>Sarmatemys</i>, <i>Sakya</i> etc.) in having a much less developed femoro-anal notch and shorter xiphiplastral processes. Other skeletal elements (neural and costal plates) share general geoemydid morphology and we tentatively assign them to the same taxon.</p>Published as part of <i>Yanenko, V. & Kovalchuk, О., 2023, Late Miocene Turtles Of Grytsiv (Western Ukraine) With Rodent Gnaw Marks On The Carapace Surface, pp. 311-322 in Zoodiversity 57 (4)</i> on page 315, DOI: 10.15407/zoo2023.04.311, <a href="http://zenodo.org/record/10831776">http://zenodo.org/record/10831776</a>
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
Dispelling the Myths Behind First-author Citation Counts
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
