Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Dodatne informacije o vodnih hroščih povodja gornje Neretve in reke Zalomke
Get PDFAs a follow-up to the investigation of the water beetle fauna of the upper course of the Neretva River in 2022, during the second »Neretva Science Week« in June 2023, additional tributaries were sampled and the presence of the endemic Bosnian species Hydraena bosnica has been confirmed (male specimens were collected). Additionally, three springs located at the slopes of the Neretva Valley were examined. Zalomka River exhibited an entirely different water beetle assemblage in comparison to that of the Neretva River and its tributaries, resulting from its intermittent character.Kot nadaljevanje raziskovanja favne vodnih hroščev zgornjega toka reke Neretve v letu 2022 smo na drugem »Tednu znanosti Neretva« junija 2023 vzorčili dodatne pritoke. Potrdili smo prisotnost bosanske endemične vrste Hydraena bosnica (moški osebki). Poleg tega smo povzorčili tri izvire na obronkih doline Neretve. Reka Zalomka ima popolnoma drugačno združbo vodnih hroščev kot Neretva s pritoki, kar je posledica njenega presihajočega značaja.
Apstrakt. Dodatne informacije o vodenim tvrdokrilcima sliva gornje Neretve i rijeke Zalomke – Kao nastavak istraživanja faune vodenih insekata gornjeg toka rijeke Neretve započetog 2022. godine, istraživanje je nastavljeno tokom Druge sedmice nauke (jun 2023. godine). Prikupljani su uzorci sa novih lokaliteta i potvrđeno je prisustvo bosanskohercegovačke endemske vrste Hydraena bosnica (muški primjerci). Uz to, prikupljeni su uzorci sa još tri izvora sa padina iznad rijeke Neretve. Rijeka Zalomka ima potpuno drugačiju zajednicu vodenih insekata od rijeke Neretve i njenih pritoka, što je rezultat njenog povremenog toka
Variations on the Author
Get PDF“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
Get PDFWe 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
Prispevek k poznavanju vodnih hroščev sensu lato (Coleoptera) iz zgornjega toka reke Neretve v Bosni in Hercegovini
Get PDFAltogether, 57 species of water beetles sensu lato (Coleoptera) belonging to 11 families (Dytiscidae, Dryopidae, Elmidae, Georissidae, Gyrinidae, Hydraenidae, Helophoridae, Heteroceridae, Hydrophilidae, Limnichidae and Scirtidae) are presented based on a survey carried out in the upper section of the Neretva River. The Georissidae with two species, Georissus costatus Castelnau, 1840 and G. cf. laesicollis Germar, 1832, are reported for the first time from Bosnia and Herzegovina with certainty. Additional new records comprise Hydraena vedrasi Orchymont, 1931, Limnebius paganettii Ganglbauer, 1904, Cercyon ustulatus Preyssler, 1790, Dryops lutulentus (Erichson, 1847) and Limnichus incanus Kiesenwetter, 1851. The most speciose family collected were Hydraenidae with 18 species, seven endemic to the Balkans.Skupno smo v raziskavi, opravljeni v zgornjem delu reke Neretve, našli 57 vrst vodnih hroščev sensu lato (Coleoptera), pripadajočih 11 družinam (Dytiscidae, Dryopidae, Elmidae, Georissidae, Gyrinidae, Hydraenidae, Helophoridae, Heteroceridae, Hydrophilidae, Limnichidae in Scirtidae). Prvič objavljamo zanesljiv podatek o najdbi družine Georissidae z dvema vrstama, Georissus costatus Castelnau, 1840 in G. cf. laesicollis Germar, 1832 v Bosni in Hercegovini. Dodatno navajamo nove podatke za Hydraena vedrasi Orchymont, 1931, Limnebius paganettii Ganglbauer, 1904, Cercyon ustulatus Preyssler, 1790, Dryops lutulentus (Erichson, 1847) in Limnichus incanus Kiesenwetter, 1851. Najbolj vrstno pestra družina so bili Hydraenidae z 18 vrstami, sedem endemičnih za Balkan.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
No full textWe 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
