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
Canine coronavirus infection in Turkish dog population
No full textCanine coronavirus (CCOV) is one of the most important viral agents affecting the gastrointestinal system of dogs. In this study virological and serological investigations were performed to demonstrate the existence and prevalence of CCoV infection in a Turkish dog Population. A total of 269 animals were subjected to the study. Of 179 dogs tested for CCoV antibodies, 112 (62.5%) were found to be positive by serum neutralization test, while 133 (74.3%) were positive by ELISA. The highest prevalence (94.2%) was detected in kennel dogs. Detection of CCoV genome in faeces was performed in samples from 90 diarrhoeic Puppies by reverse transcription-polymerase chain reaction. Fourteen (15.5%) faeces were positive for CCoV RNA, five of which were characterized Lis CCoV type 1. The widespread CCoV infection in the Turkish clog, population may be attributed Lis an important cause Of viral diarrhoea in dogs
Seroprevalence of canine coronavirus in dogs in Turkey
No full textCanine coronavirus (CCoV) is among important agents of dogs which affects gastrointestinal tract. In this study it was aimed to investigate existence and prevalence of CCoV infections in dogs in Turkey.
For this purpose, 179 blood sera, collected from 7 provinces in different regions of the country were screened for CCoV antibodies by neutralization and ELISA techniques. Of these samples, 112 were from household dogs, 21 from stray dogs, 35 from a kennel and 11 were from municipality shelter. Ages of animals sampled were between 5 months and 7 years old, and none of them were recorded to have vaccination history against CCoV.
One hundred and twelve of 179 dogs (62.5%) were positive in neutralization assay while ELISA detected 133 (74.3%) dogs as positive. Difference between positivity rates of techniques used were found to be statistically important (p<0.05). From the aspect of breeding types, the highest prevalence (94.2%) was detected in the kennel, and it was followed by municipality shelter (72.7%), stray dogs (71.4%) and household dogs (68.7%). There was a significant difference (p<0.05) among seroprevalence values detected in kennel and other types of breeding.
Results of this study demonstrate that CCoV infections are widespread in Turkish dog population, and kennels create the highest risk group as well as shelters
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
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
