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
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
Prostate cancer investigation in the region of Thessaly, using advanced imaging modalities and histological correlation
No full textIntroduction –Objectives: The PhD thesis explores the imaging approach of prostate cancer, focusing on the use of multiparametric magnetic resonance imaging (mpMRI) in combination with transrectal ultrasound-guided biopsy (Fusion-guided mpMRI-TRUS). The work aims to evaluate the diagnostic accuracy of this method compared to traditional systemic biopsies, as well as to improve clinical results through more accurate detection and categorization of cancer foci. Methodology: The study methodology includes the analysis of data from 185 patients who underwent mpMRI and fusion-guided mpMRI-TRUS biopsy. Patients were selected based on specific criteria and statistical analysis of the data was performed with SPSS Statistics version28. The methodology includes a description of the imaging and biopsy procedures, as well as the parameters used to evaluate the findings. Results: A total of 81/185 (43.8%)cancer-positive cases were identified. 23/81 (28.4%) cases with non-clinically significant prostate cancer-insPCa and 58/81 (71.6%) cases with clinically significant prostate cancer-csPCa. There was a statistically significant difference in overall adenocarcinomas detection between methods (p = .035, McNemar test). In addition, there was a statistically significant difference in the detection of insPCa between the two methods (p = .004, McNemar test). The systemic biopsy detected 13 patients with insPCa more (14.4%) than the targeted biopsy method. However, there is no statistical difference in the detection rate of csPCa between the two methods (p = 1, McNemar test). When both techniques were combined, more instances of csPCa were identified. Conclusions: The thesis concludes that multiparametric MRI in combination with targeted transrectal ultrasound biopsy is a reliable and effective method for detecting prostate cancer. This approach allows clinically significant cancers to be detected more accurately, while reducing the number of unnecessary biopsies. In addition, mpMRI is used as a screening tool for patients before biopsy, providing important information for clinical decision-making. The study suggests using mpMRI and fusion-guided mpMRI-TRUS along with systemic biopsy as a standard for diagnosing prostate cancer, highlighting the advantages of this combination over traditional biopsy methods. Finally, the thesis emphasizes the importance of continuous training and specialization of physicians in using these technologies to achieve optimal clinical results.Εισαγωγή –Στόχοι: Η διδακτορική διατριβή διερευνά την απεικονιστική προσέγγιση του καρκίνου του προστάτη, με επίκεντρο τη χρήση της πολυπαραμετρικής μαγνητικής τομογραφίας (mpMRI) σε συνδυασμό με διορθική υπερηχογραφική καθοδηγούμενη βιοψία (Fusion-guidedmpMRI-TRUS). Η εργασία έχει ως στόχο την αξιολόγηση της διαγνωστικής ακρίβειας αυτής της μεθόδου σε σύγκριση με τις παραδοσιακές συστηματικές βιοψίες, καθώς και τη βελτίωση των κλινικών αποτελεσμάτων μέσω της ακριβέστερης ανίχνευσης και κατηγοριοποίησης των καρκινικών εστιών. Μεθοδολογία: Η μεθοδολογία της μελέτης περιλαμβάνει την ανάλυση δεδομένων από 185 ασθενείς που υποβλήθηκαν σε mpMRIκαι βιοψία με συστηματική και fusion-guidedmpMRI-TRUS. Οι ασθενείς επιλέχθηκαν με βάση συγκεκριμένα κριτήρια(DRE, PSA, κλινική υποψία)και η στατιστική ανάλυση των δεδομένων πραγματοποιήθηκε με το SPSS έκδοση 28. Η μεθοδολογία περιλαμβάνει περιγραφή των διαδικασιών απεικόνισης και βιοψίας, καθώς και των παραμέτρων που χρησιμοποιήθηκαν για την αξιολόγηση των ευρημάτων. Αποτελέσματα: Συνολικά εντοπίστηκαν 81/185 (43,8%)περιπτώσεις θετικές για καρκίνο. 23/81 (28,4%) περιπτώσεις με μη κλινικά σημαντικόκαρκίνο του προστάτη-insPCaκαι 58/81 (71,6%) περιπτώσεις με κλινικά σημαντικό καρκίνο του προστάτη-csPCa. Υπήρξε στατιστικά σημαντική διαφορά στη συνολική ανίχνευση αδενοκαρκινωμάτων μεταξύ των μεθόδων (p = .035, δοκιμή McNemar). Επιπλέον, υπήρξε στατιστικά σημαντική διαφορά στην ανίχνευση insPCa μεταξύ των δύο μεθόδων (p = .004, δοκιμή McNemar). Η συστηματική βιοψία ανίχνευσε 13 ασθενείς με insPCa περισσότερους (14,4%) από τη στοχευμένη μέθοδο βιοψίας. Ωστόσο, δεν υπήρξε στατιστική διαφορά στο ποσοστό ανίχνευσης του csPCa μεταξύ των δύο μεθόδων (p = 1, δοκιμή McNemar). Όταν συνδυάστηκαν και οι δύο τεχνικές, εντοπίστηκαν περισσότερες περιπτώσεις csPCa. Συμπεράσματα: Η διατριβή καταλήγει στο συμπέρασμα ότι η πολυπαραμετρικήμαγνητική τομογραφία σε συνδυασμό με τη στοχευμένη διορθική υπερηχογραφική βιοψία αποτελεί μια αξιόπιστη και αποτελεσματική μέθοδο για την ανίχνευση του καρκίνου του προστάτη. Αυτή η προσέγγιση επιτρέπει την ανίχνευση κλινικά σημαντικών καρκίνων με μεγαλύτερη ακρίβεια, μειώνοντας παράλληλα τον αριθμό των περιττών βιοψιών. Επιπλέον, η mpMRI χρησιμοποιείται ως εργαλείο διαλογής των ασθενών πριν τη βιοψία, παρέχοντας σημαντικές πληροφορίες για τη λήψη κλινικών αποφάσεων. Η μελέτη προτείνει τη χρήση της mpMRIκαι της fusion-guidedmpMRI-TRUSμαζί με τη συστηματική βιοψία, ως πρότυπο για τη διάγνωση του καρκίνου του προστάτη, επισημαίνοντας τα πλεονεκτήματα αυτού του συνδυασμού σε σχέση με τις παραδοσιακές μεθόδους βιοψίας. Τέλος, η διατριβή τονίζει τη σημασία της συνεχούς εκπαίδευσης και εξειδίκευσης των ιατρών στη χρήση αυτών των τεχνολογιών για την επίτευξη βέλτιστων κλινικών αποτελεσμάτων

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
