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
The effect of comorbidities on the choice of tyrosine kinase inhibitors in patients with chronic myeloid leukemia
No full textTyrosine kinase inhibitors (TKIs) approved for chronic myeloid leukemia known to have similar efficacies but different safety profiles. Therefore, the choice of patient-specific treatments is driven by factors such as tolerability and adverse event profile of TKIs. This review article examines the most up-to-date data and provides practical recommendations for clinical approaches. Nilotinib and ponatinib should be avoided in patients with cardiovascular risk factors, dasatinib in patients with lung damage and bosutinib and nilotinib in patients with liver disease. Considering that certain comorbidities predispose some patients to developing severe adverse events when receiving TKIs, the first- and second-line treatment of chronic myeloid leukemia should be tailored to each patient’s individual condition
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
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
The clinical impacts of the controlling nutritional status score on patients with Hodgkin lymphoma
No full textOBJECTIVE: The aim of the study was to evaluate the clinical importance and potential mechanisms of controlling nutritional status (CONUT) score as a prognostic tool for Hodgkin lymphoma (HL). PATIENTS AND METHODS: Diagnosed with HL, 307 patients were included in the study. Patients’ demographic data, stages, B symptoms, extranodal involvement, presence of bulky disease, laboratory findings, treatments, treatment responses, nutritional status, and overall survival (OS) rates were evaluated from the hospital records. The primary endpoint of our study was to evaluate and classify newly diagnosed HL patients under the CONUT score. The secondary endpoint was to indicate any relationship between nutritional status, CONUT score, and other prognostic factors and OS. RESULTS: Of 307 patients (173 males, 134 females), the mean age was 41.58±16.26 (ranging between 18-82 years). The most common type of malignancy was nodular sclerosis (72.53%). To the receiver operating characteristic (ROC) curve analysis, the best cut-off point was 2.5 to predict mortality. Eigthy-five (27.7%) and 222 (72.3%) patients had ≥3 and ≤2 CONUT scores, respectively. Twenty-four (10.80%) and 23 (27.10%) cases were also mortal in the patients with ≤2 and ≥3 CONUT scores, respectively (p<0.001). Survival times were significantly lower in those with higher (≥3) CONUT scores (p<0.001) than among the other patients. CONCLUSIONS: Evaluation of nutritional status plays an important role in the response and survival of those with hematological malignancies. Malnutrition can reduce patients’ tolerance to chemotherapy and increase the risk of secondary infections. In this study, undernutrition evaluated with the CONUT score was demonstrated to be a potential independent prognostic factor for OS in patients with HL
