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
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
Craniometric analysis of sexual dimorphism of the modern Croatian population using MSCT
No full textUvod:
Forenzička antropologija je primijenjena grana biološke antropologije koja s pomoću bioantropoloških metoda rekonstruira događaje i identificira sudionike u sklopu sudskih i/ili policijskih istraga. Osnovni korak u identifikaciji je procjena spola, koja se na kostima može učiniti morfološki, osteometrijski i analizom DNK-a. Nedostatak morfološke procjene spola je u tome što ovisi o iskustvu osobe koja vrši procjenu. DNK analiza također ima svoja ograničenja poput kontaminacije uzoraka, invazivnosti u smislu daljnjeg oštećenja kolekcije uzimanjem uzoraka za analizu te visoke cijene postupka. Osteometrijske metode su populacijski specifične, te je za svaku populaciju potrebno izraditi standarde. U prošlosti su koštane zbirke bile jedini izvor forenzičko antropoloških mjerenja. Nedostatci koštanih zbirki su ograničeni broj dostupnih koštanih ostataka koji su očuvani u optimalnoj mjeri za daljnje proučavanje. Isto tako, mnogim ostatcima nije moguće procijeniti spol, najčešće zbog nedovoljne očuvanosti uslijed tafonomskih promjena. Vremenom su slikovne metode, korištene u radiologiji svakodnevno (poput MSCT-a) postale važan dio forenzičke antropologije. Razvojem softvera za MSCT, postalo je moguće dobiti trodimenzionalni model čime nastaje pojam virtualne antropologije. U ovoj disertaciji je upravo pomoću MSCT-a i virtualne antropologije po prvi puta ustanovljeno koje standardne kraniometrijske mjere su spolno dimorfične i u kojoj mjeri za suvremenu hrvatsku populaciju.
Materijali i metode:
Provedeno je retrospektivno istraživanje na ukupno 414 arhivskih CT snimki angiografije glave i vrata punoljetnih pacijenata (98 odraslih muškaraca i 97 odraslih žena iz KBC-a Zagreb i 109 odraslih muškaraca i 110 odraslih žena iz KBC-a Split). Isključni kriteriji su bili debljina slojeva veća od 1 mm te patološke i traumatske promjene lubanje koje bi mogle utjecati na mjerenje, odnosno postavljanje točaka. DICOM podatci dobiveni CT pregledima importirani su u Stratovan Checkpoint softver u kojemu su učitane rekonstrukcije u koštanom prozoru kako bi se na 2D (aksijalni, koronalni i sagitalni presjek) i 3D modelu lubanje pozicioniranjem anatomskih točki izmjerilo dvadeset i osam standardnih forenzičkih mjera.
U svrhu bolje preciznosti i brzine rada prije svakog postupka mjerenja svih 414 lubanja na CT pregledima, učitani su predlošci s izmijenjenim redoslijedom točaka u usporedbi s literaturnim popisom točaka kako bi se optimiziralo postavljanje točaka u istoj ravnini odnosno pregledu. Anatomske točke prikupljene na svakom CT pregledu izvezene su kao .nts datoteke i učitane u R (verzija 3.6.2) i Rstudio (verzija 1.2.5033) koristeći se „geomorph“ paketom. Isti softver je korišten i za izračunavanje interorijentirskih duljina koje predstavljaju standardne kranijske mjere. Zbog međumjeriteljske i unutarmjeriteljske pogreške, mjerenja su ponovljena na 35 uzoraka. Učinjena je statistička obrada podataka te izvedene diskriminantne funkcijske jednadžbe za procjenu spola, za pojedinačne mjere koje su pokazale statistički značajni spolni dimorfizam te za njihove kombinacije.
Rezultati:
Analizom dobivenih podataka ustanovljene su regionalne razlike u određenim kraniometrijskim mjerama između žena iz Splita i Zagreba i između muškaraca iz Splita i Zagreba. Žene i muškarci iz Zagreba imaju kraću i širu lubanju u odnosu na žensku i mušku populaciju iz Splita. Određene kraniometrijske mjere su imale nešto višu unutarmjeriteljsku i međumjeriteljsku pogrešku te su isključene iz daljnje analize. Ukupno sedam kraniometrijskih mjera (širina između jabučica, biaurikularna širina, najmanja čeona visina, gornja širina lica, visina nosa, biorbitalna širina i bimaksilarna širina) zadovoljile su kriterije ponovljivosti i nisu pokazale regionalne razlike, a pokazale su statistički značajni spolni dimorfizam. Za sve navedene mjere izrađene su pojedinačne diskriminantne funkcije za procjenu spola čija ukupna točnost varira od 84,3 % za mjeru širina između jabučica do 66,7 % za mjeru najmanja čeona širina. Također su izrađene i diskriminantne funkcije za dvije kombinacije mjera čija je ukupna točnost 86,2 % i 85,5 %.
Zaključak:
Sedam kraniometrijskih mjera je pokazalo statistički značajan spolni dimorfizam u suvremenoj hrvatskoj populaciji te su primjenjive u forenzičkim slučajevima. Izrađene su diskriminantne funkcije procjene spola za svaku pojedinačnu mjeru te za dvije kombinacije mjera. Rezultati pokazuju da su standardne mjere kranija ograničeno primjenjive za procjenu spolnoga dimorfizma te potrebu da se u budućim istraživanjima analiziraju sve moguće mjere koje se mogu dobiti iz točaka kranija, a ne samo standardne kraniometrijske mjere.Forensic anthropology is a subfield of biological anthropology that utilizes bioanthropological methods to reconstruct events and identify participants in legal and/or police investigations. The initial step in identification involves assessing the sex, which can be done morphologically, osteometrically, and through DNA analysis on bones. Osteometric methods are population specific, requiring standards for each population. There is no research on sexual dimorphism in cranial features (all standard craniometric measurements) in the contemporary Croatian population. This retrospective study aimed to investigate cranial sexual dimorphism in the contemporary Croatian population using MSCT. Analysis of the obtained data revealed regional differences in certain craniometric measurements between women from Split and Zagreb, as well as between men from Split and Zagreb. The female and male population from Zagreb exhibited shorter and wider skulls compared to the female and male population from Split. Some craniometric measurements had unacceptably high intra- and inter-observer errors and were excluded from further analysis. A total of seven craniometric measurements (ZYB, AUB, WFB, UFBR, NLH, EKB, ZMB) met repeatability criteria, showed no regional differences, and demonstrated statistically significant dimorphism. We developed nine linear discriminant models for sex estimation, seven univariate and two multivariate using stepwise analysis

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.
