Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
First Record of the Rhadinorhynchus trachuri (Acanthocephala, Rhadinorhynchidae) Parasite on the Auxis rochei from the Marine Waters of Lattakia, Syria
No full textThe aim of this research was to deal with identification of the types of endoparasites observed in the fish species A. rochei caught in the marine waters of Lattakia, the site of infection and prevalence of the parasites found during the current study to be protected from the damages of this parasite. They research was carried out in Department of Zoology, Faculty of Sciences, Latakia University between October 2021 and September 2023. during the research, 263 live specimens of A. rochei were collected; they were taken from the commercial fishermen from Ras Al Basit – Lattakia. All specimens were transferred fresh to laboratory of Hydrobiology in Faculty of Science at Latakia University. Eleven fish were infected by parasites. Fish were dissected and then their body cavities and internal organs were examined. Some parasites were observed inside intestines of some fish; these parasites were collected, counted, processed, examined and saved, and classified according to criteria applied in similar studies. Infection prevalence (%) and mean intensity follow the recommendations of (Bush et al., 1997). In the result, 11 out of 263 examined specimens of A. rochei were infected with 27 parasites found in their intestines. The infection prevalence was 4.18% and its density was 2.45 parasite/ fish. Morphological features (body, eggs, and hooks) of Rhadinorhynchus trachuri agreed with study of Amin (2020). Worms collected were mature females with an orange color, body composed of proboscis, neck and trunk. trunk elongated, sub-cylindrical, somewhat swollen anteriorly, a spinose, and covered with transverse striated cuticle. Proboscis is cylindrical, stout, claviform, densely armed with 12 alternating rows of strongly re-curved 23–25 hooks. In conclusion, the result of this study showed the presence of the parasite R. trachuri inside the intestines of the A. rochei fish that inhabiting the marine waters of the Syria coast of Lattakia. This is the first record of infection of A. rochei fish by R. trachuri in Mediterranean Sea generally and Syrian marine waters especially. In our knowledge, this article will contribute to the ichthyhelminthological studies of marine fish in Syria
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
FIRST RECORD OF THE NEMATODA PARASITES FROM THE FAMILY ANISAKIDAE ON THE Euthynnus alletteratus (Rafinesque, 1810) CAUGHT IN THE MARINE WATERS OF LATTAKIA – SYRIA
Full text linkThe E. alletteratus is one of the most desirable fish for consumption in general, because of its high nutritional value, Moreover, is one of the richest fish in protein. Severe infection with pathogens, especially parasites, can cause various functional disorders and this affects the quality of its meat.
The A. simplex is one of the most clinically important parasites in human health, the disease in humans manifests nonspecifically, however the consumption of raw or semi-raw seafood is crucial information to link the presence of the parasite with the disease.
Therefore, the identification of parasites that parasitize on E. alletteratus is of great importance, as we found (during current research) the parasite Anisakis simplex (Rud, 1809) on the outer surface of the digestive system of one of them.
The present study was considered as the first report of anisakid larvae from E. alletteratus in the Syrian water
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
