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
Sample preparation and the pilot testing of an oxygen consumption test that assesses the extent of pyrrhotite oxidation in sulfide-bearing concrete aggregates
Get PDFNår betongtilslag inneholder magnetkis, et mineral som består av jern og svovel, kan dette føre til betydelige skader på betongkonstruksjoner. I 2016 ble en kanadisk testprosedyre introdusert. Målet med denne testprosedyren er å finne ut hvilke sulfidholdige tilslag som eventuelt kan brukes i betong.
Denne masteroppgaven har fokus på trinn to i den kanadiske testprosedyren, nemlig the oxygen consumption test, «OCT». Testen måler hvor mye oksygen som forbrukes av tilslagsmaterialet i en hermetisk lukket reaksjonscelle (beholder) i løpet av tre timer. Prøver fra fire tilslagstyper, to fra Norge og to fra Canada, ble preparert og etterpå testet med OCT som en del av denne oppgaven. Fokuset var å bidra til å bygge opp et eksperimentelt oppsett for OCT i Norge, samt vurdere om resultatene man får er fornuftige. Oppredningen av tilslag var spesielt satt i fokus, og målet var å utvikle en oppredningsprosedyre som både er effektiv og fri for kontaminering.
Det eksperimentelle oppsettet hos SINTEF Betonglaboratoriet er fult operativt. En oppredningsprosedyre som kombinerer wolfram- og stålutstyr, er funnet å være effektiv og med lav risiko for kontaminering av prøver.
Partikkelstørrelsen til tilslagsmaterialet er en av de viktigste parameterne til OCT. Partikkelstørrelsen til testprøvene ble bestemt gjennom sikting og gjennom en optisk metode (laser scattering). Store forskjeller mellom de to metodene ble avdekket, spesielt siden den optiske metoden viser større antall partikler 150 μm.
Alt i alt, resultatene fra OCT virker rimelige, spesielt for de norske tilslagene. Resultatene for de kanadiske tilslagene var mye lavere enn referanseverdiene i Canada, noe som kan tyde på en systematisk feilkilde som kunne ha påvirket resultatene fra pilot-testingen. En mulig feilkilde burde derfor undersøkes nærmere.
Et av de norske tilslagene ble testet i OCT med en lengere testperiode (16.7h sammenlignet med 3.5h). Den nye testperioden førte til betydelig høyere oksygenforbruk i reaksjonscellen.
Gjennom erfaringen fra denne masteroppgaven, og litteraturstudiet om OCT, ble det mulig å utvikle en norsk OCT-prosedyre som inkluderer oppredning av tilslagsmaterialet.The presence of pyrrhotite, a mineral consisting of iron and sulfur, in concrete aggregates can cause considerable damage to concrete structures. In 2016, a Canadian testing protocol was introduced, the aim of which was to investigate whether sulfide-bearing aggregates can be safely used in concrete.
This master’s thesis focused on the second step of the Canadian testing protocol, the oxygen consumption test (OCT). This test measures the oxygen consumption of aggregate material in a hermetically closed cell over three hours. Samples from four aggregates, two Norwegian and two Canadian, were prepared and then tested with the OCT as part of this study. The focus was to help establish the experimental setup of the OCT in Norway and to assess whether that the obtained results are reasonable. The process of sample preparation, in particular, was investigated, and the aim was to develop a methodology that was both efficient and contamination-free.
The OCT setup at the SINTEF Concrete Laboratory is fully operative. One sample preparation process involving steel and tungsten carbide equipment was preliminarily found to be efficient and free of iron contamination.
The particle size of the aggregate material is one of the parameters of the OCT. The particle size of test samples was determined both by sieving and by laser scattering (optical technique). The two methods gave significantly different particle size distributions.
The OCT results (oxygen consumption) seem reasonable, particularly for the Norwegian aggregates. However, the results for the two Canadian aggregates were significantly lower than the oxygen consumption reported by earlier work on the OCT in Canada. This might be due to a systematic source of error that requires further investigation.
Testing on one of the Norwegian aggregates preliminarily showed that increasing the duration of the OCT (to 16.7h) can lead to significantly higher oxygen consumption.
A detailed procedure for the oxygen consumption testing in Norway, including the sample preparation process, was developed based on the existing literature on the OCT and the experience acquired through the work on the master’s thesis

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.
