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
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
Immunohistochemical and Molecular Genetic Methods in the Head and Neck Pathology
Full text linkCurrent doctoral thesis is dealing with morphology, immunohistochemistry, molecular genetics and biological behavior of head and neck tumors with a particular emphasis on salivary gland and sinonasal lesions. Dr. Martina Baneckova has focused on this topic during her postgraduate studies at Charles University, Medical Faculty in Pilsen, in the years 2017 - 2020. In her publication activity, the author focused on rare tumors of the head and neck. A total of 9 publications were published over a span of three years are presented in a form of a commentary. Four of them are first-author papers and these are introduced briefly below. The first study entitled "Mammary analog secretory carcinoma of the nasal cavity: Characterization of 2 cases and their distinction from other low-grade sinonasal adenocarcinomas" deals with the relationship of newly described entities, secretory carcinoma (SC) of the nasal cavity and ETV6-rearranged low-grade sinonasal adenocarcinoma (LG SNAC). It is important to distinguish these 2 entities because of different clinical behaviors. Low-grade non-ITAC, including ETV6-rearranged LG SNAC mostly behave in an indolent manner, whereas SC is a malignancy with metastatic potential. It is important to be aware of the possible occurrence of SC in the sinonasal region, as in this area..
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
Molecular genetic characteristics of salivary gland tumors in differential diagnosis and prognosis prediction
Full text linkMolecular genetic characteristics of salivary gland tumors in differential diagnosis and prognosis prediction Abstract: In the presented manuscript the author summarizes the current knowledge on molecular biomarkers of salivary gland cancer, focusing on tumor-type specific fusion oncogenes and their use as diagnostic, prognostic and therapeutic biomarkers. In detail, the author deals with adenoid cystic carcinoma (AdCC), the second most common salivary gland cancer. New facts of its biological behavior as well as new fusion oncogenes probably responsible for its carcinogenesis were described in the last few years. A retrospective case series evaluating 27 patients suffering from AdCC, who were treated at the University Hospital in Pilsen in the last 30 years (1986- 2016), is presented in this study. The following characteristics were observed: age, gender, tumor location, clinical stage at diagnosis, presence of regional and distant metastases, tumor grade, duration of follow-up, treatment and outcomes. Detection of the 1p36 deletion and the t(6;9)(q22-23;p23-24) chromosomal translocation resulting in the MYB-NFIB gene fusion were performed. The incidence of AdCC in minor salivary glands, submandibular gland, parotid gland and sublingual gland was 41 %, 26 %, 22 % and 11% respectively. The following staging..
