Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
Die teoretiese begronding vir die ontwerp van ’n nagraadse toets van akademiese geletterdheid in Afrikaans
No full textEnglish: The low levels of academic literacy of students at South African universities are a well-known problem, and one which is increasingly being identified as one of the prime reasons for a lack of academic performance and low throughput rates. The employment of academic literacy tests by tertiary institutions is a direct result of the need to identify which students are potentially at risk, and would therefore need additional academic support in order to complete their degree courses successfully in the prescribed time. One such test that has been used for some time nationally and internationally to measure the academic literacy levels specifically of postgraduate students is the Test of Academic Literacy for Postgraduate Students (TALPS). This test, however, is currently unavailable in any of the other official languages. This study therefore confirms the need to promote multilingualism at postgraduate level, even in the face of this goal at present being increasingly undermined by the favouring of a monolingual English dispensation at university. More specifically, this and previous studies acknowledge the lack of an Afrikaans alternative for TALPS as a serious shortcoming in language assessment at tertiary level. In response to this need the study intends to design, develop, test out and refine a postgraduate of academic literacy in Afrikaans (TAGNaS – Toets van Akademiese Geletterdheid vir Nagraadse Studente). This is done with reference to a theoretical-analytical framework of constitutive and regulative design principles that relate assessment design on the one hand to intrinsic, conventional conditions such as reliability and validity and, on the other, take account of social impacts such as transparency, accountability, and fairness. For the theoretical justification of TAGNaS multiple sets of evidence are presented, among which are the articulation of the theoretical rationale for the test (a key element of construct validity) and an argument integrating several statistical analyses of the pilot test results. Since the test rests theoretically upon a recently modified definition of academic literacy, experimentation with new or modified subtests and task types was part of the investigation. The results indicate that it can be highly productive to treat the operationalization of the construct with ingenuity and creativity, and also that experimentation with the challenges that new articulations of established constructs provide can be successfully accomplished.Afrikaans: Die lae akademiese-geletterdheidsvlakke van studente aan Suid-Afrikaanse
universiteite is ’n goedbekende probleem wat toenemend as een van die
hoofoorsake van akademiese onderprestering en swak deurvloeikoerse
bestempel word. Die gebruik van akademiese geletterdheidstoetse by tersiêre
instansies is ’n direkte gevolg van die behoefte om te bepaal watter studente
potensiële risikostudente is wat heel waarskynlik bykomende akademiese
ondersteuning gaan benodig ten einde hulle graadkursusse binne die
voorgeskrewe tydperk met sukses te voltooi.
Een so ’n toets wat reeds ’n geruime tyd lank nasionaal en internasionaal gebruik
word om die akademiese geletterdheidsvlak van spesifiek voornemende
nagraadse studente te meet, is die Test of Academic Literacy for Postgraduate
Students (TALPS). Hierdie toets is egter tans in geen van die amptelike landstale
behalwe Engels beskikbaar nie. Gevolglik bevestig hierdie studie die behoefte
aan die bevordering van veeltaligheid op nagraadse vlak, selfs in weerwil
daarvan dat hierdie strewe toenemend in die huidige universiteitbestel ten gunste
van Engels-eentaligheid ondermyn word. Meer spesifiek, beskou hierdie en
vorige studies dit as ʼn leemte in die gebied van taaltoetsing op tersiêre vlak dat
daar tans geen Afrikaanse alternatief vir TALPS beskikbaar is nie.
In antwoord op hierdie behoefte gee hierdie studie uitvoering aan die ontwerp,
loodsing en verfyning van ʼn nagraadse toets van akademiese geletterdheid in
Afrikaans (TAGNaS). Dit word gedoen ooreenkomstig ’n wetenskaplikteoretiese
raamwerk van konstitutiewe en regulatiewe ontwerpbeginsels wat
verantwoordelike toetsontwerp in verband bring met, aan die een kant, die
inagneming van instrinsieke, konvensionele voorwaardes soos betroubaarheid en
geldigheid, en, aan die ander kant, die verrekening van sosiale impakte soos
deursigtigheid, verantwoordbaarheid en regverdigheid. Vir die teoretiese
begronding van TAGNaS word ’n menigvuldigheid van bewyse ter stawing
gebied, waaronder ’n artikulasie van die teoretiese rasionaal waarop die toets
gebaseer is (’n kernaspek van konstrukgeldigheid), asook ’n beredeneerde
opgawe van verskeie statistiese ontledings van die loodstoetsresultate.
Aangesien die teoretiese basis van die toets uit ’n onlangs bygewerkte definisie
van akademiese geletterdheid bestaan, maak eksperimentering met gewysigde
en/of nuwe subtoetse en/of taaktipes deel van hierdie ondersoek uit. Die
bevindinge dui daarop dat om vindingryk en kreatief om te gaan met die
operasionalisering van ’n konstruk besonder suksesvol en verruimend kan wees,
en dui aan dat eksperimentering met die vereistes wat nuwe artikulasies van
gevestigde konstrukte stel, geslaag kan wees.Inter-Institutional Centre for Language Development and Assessment (ICELDA)Suid-Afrikaanse Akademie vir Wetenskap en Kuns (SAAWK
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

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.
