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
The role of free radicals and homocysteine in the development of arteriosclerosis
No full textIntroduction The oxidative hypothesis of atherosclerosis proposes thatoxidative modification of low density lipoprotein (LDL) plays a critical role inatherogenesis The evaluation of LDL oxidation in vivo is therefore veryimportant However, data concerning the evaluation of the above biochemicalmarker is very limited in clinical practiceAim This study was conducted to test the hypothesis that plasma levelsof oxLDL reflect atherosclerosis and determine the clinical significance in themeasurement of circulating oxLDL and autoantibodies against them as well astheir correlation with homocysteine and lipid parameters m the diagnosis andseventy of coronary heart diseaseMaterial-Methods A total of 273 individuals were examined 41 sufferingfrom unstable angina pectoris (UAP), 62 suffering from stable angina pectoris(SAP) and 170 healthy control subjects We used a sensitive method for detectmgoxLDL that is based on a direct sandwich technique (ELISA) in which twomonoclonal antibodies are directed against separate antigenic determinants onthe oxidized apokpoprotein-B molecule along with an another enzymeimmunoassay designed to determme human antibodies to oxidized LDL (antioxLDL)directly m serum Total homocysteine (HCY) was evaluated by means of afully automated fluorescence polarization immunoassayResults Patients with UAP exhibited marked elevations m oxLDL levels ascompared to patients with SAP (161 2±28 4 vs 119 2±26 6, p<0 001) and thecontrol subjects (67±18 8, p<0 001) The difference in oxLDL levels betweenpatients with SAP and the control group was also statistically significantSimilarly, patients with UAP showed marked elevations m anti-oxLDL antibodiescompared to both patients with SAP (602 2±62 2 vs 510 8±50 3, p<0 001) andcontrol subjects (368±79 6, p<0 001) The difference in anti-oxLDL levels betweenpatients with SAP and the controls was also statistically significant OxLDL levelswere not correlated with age in any of the groups studied Triglycerides, LDLcholesteroland total cholesterol were elevated m patients with UAP as opposed topatients with SAP and the control subjects, while HDL levels were elevated in thecontrol subjects when compared to patients with SAP and UAP Homocysteinelevels were elevated m patients suffering from UAP and SAP when compared tohealthy subjects Patients with UAP or SAP did not differ on homocysteine levelsConcusions Our findings demonstrate the presence of oxLDL in vivo, itsstrong association with homocysteine, with coronary artery disease as well aswith the severity of its clinical presentation.Εισαγωγή Η "οξειδωτική" θεωρία χης αθηροσκληρυνσης υποστηρίζει οτι ηοξειδωτική τροποποίηση των χαμηλής πυκνότητας λιποπρωτεΐνων (LDL) διαδραματίζει ένανκεντρικό ρολό στην διαδικασία της αθηρογενεσης Η αξιολόγηση της οξείδωσης των LDL invivo είναι επομένως πολύ σημαντική Ωστόσο, βιβλιογραφικές αναφορές σχετικές με τονπροσδιορισμό του βιοχημικού αυτού δείκτη στην καρδιαγγειακή νόσο και την χρησιμότητατου στην διάγνωση η/και πρόγνωση της ασταθούς και σταθερής στηθάγχης είναι λιγοστέςΣκοπός Η παρούσα μελέτη πραγματοποιήθηκε με σκοπό την αξιολόγηση τηςισχύος της παραπάνω υπόθεσης, τον καθορισμό της κλινικής χρηστικότητας μέτρησηςοξειδωμένων LDL και αντισωμάτων έναντι αυτών καθώς επίσης και της πιθανής συσχέτισηςτους με λιπιδαιμικες παραμέτρους και ομοκυστεΐνη όσον άφορα στη διάγνωση καιβαρύτητα της στεφανιαίας νόσουΥλικό Μέθοδος Συνολικά εξετάστηκαν 273 άτομα 41 που έπασχαν απο ασταθήστηθάγχη, 62 που έπασχαν απο σταθερή στηθάγχη και 170 υγιή άτομα που αποτέλεσαν τηνομάδα έλεγχου Συγκεκριμένα, για την ανίχνευση των κυκλοφορουσων οξειδωμένων LDL(oxLDL) έγινε χρήση μιας ευαίσθητης ανοσοενζυμικης μεθόδου τύπου σάντουιτς (ELISA)στην οποία δυο μονοκλωνικα αντισώματα κατευθύνονται έναντι ξεχωριστών αντιγονικωνεπιτοπων της οξειδωτικά τροποποιημένης Αρο Β 100 Για τον προσδιορισμό αντισωμάτωνέναντι της οξειδωμένης LDL χρησιμοποιήθηκε μια άλλη ανοσοπροσροφητικη ενζυμικηδοκιμασία Επιπλέον καταγράψαμε το λιπιδαιμικο προφίλ των ατόμων αυτών μετρώντας τηνολική χοληστερόλη (tCHL), τα τριγλυκεριδια (TG), την HDL-χοληστερολη και την LDL-χοληστερολη Η ολική ομοκυστεΐνη (HCY) προσδιορίσθηκε με τη μέθοδο τηςανοσοφθορισμοπολωσιμετριαςΑποτελέσματα Οι ασθενείς με ασταθή στηθάγχη παρουσίασαν αυξημένα επίπεδαoxLDL σε σύγκριση με τους ασθενείς με σταθερή στηθάγχη (161,2±28,4 εναντίον119,2±26,6, ρ<0,001) και τα άτομα έλεγχου (67±18,8, ρ<0,001) Η διάφορα στα επίπεδατων oxLDL μεταξύ των ασθενών με σταθερή στηθάγχη και της ομάδας έλεγχου ήταν
