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
Clastic interbeddings and ash within lignite mined in the Konin vicinity, central Poland
Full text linkWydział Nauk Geograficznych i GeologicznychMoja rozprawa doktorska, przedstawiona Radzie Naukowej dyscypliny nauki o Ziemi i środowisku na stopień doktorski na Wydziale Nauk Geograficznych i Geologicznych (Uniwersytet im. Adama Mickiewicza) składa się z czterech wybranych publikacji. Mój udział w ich przygotowaniu mieści się w przedziale 35–100%, co zostało poświadczone przez współautorów (oświadczenia współautorów). Dwie publikacje (pierwsza i druga) poświęcone są osadom klastycznym, które tworzą przewarstwienia w pokładzie węglowym. Natomiast dwie kolejne publikacje (trzecia i czwarta) obejmują badania popiołu występującego w węglu. Tak się składa, że w okolicach Konina eksploatowany jest aktualnie (lata 2015–2021, czas realizacji badań) wyłącznie 1. środkowopolski pokład węgla brunatnego. Jego eksploatacja odbywa się w trzech odkrywkach: Jóźwin IIB, Drzewce i Tomisławice. Ważną część badań stanowiły prace terenowe, w tym sedymentologiczne. Ponadto, z każdej odkrywki pobrano liczne próbki zarówno z osadów klastycznych, jak i z pokładu węglowego. Posłużyły one do następujących badań laboratoryjnych: uziarnienia klastyków, zawartości popiołu w węglu i określenia składu chemicznego popiołu, tj. składu pierwiastkowego i tlenkowego. W wyniku działalności Kopalni Węgla Brunatnego Konin (KWB Konin) w latach 2015–2016, między dwoma ławami węgla, odsłonięte zostały osady klastyczne w odkrywce Tomisławice. Miały one kształt soczewy o długości ok. 500 m i miąższości do 1,8 m, z warstwą węgla do 20 cm w części północnej odsłonięcia. Składały się one z głównie drobnoziarnistych i dobrze wysortowanych piasków, z wyjątkiem osadów znajdujących się w stropowej oraz spągowej części, które były wzbogacone w materię organiczną. Na podstawie analizy sedymentologicznej tych osadów klastycznych (tj. ich architektury i cech teksturalno-strukturalnych) zaproponowano model ich powstania. Osady te powstały, najprawdopodobniej w wyniku dwóch powodzi, na terenie zalewowym środkowowmioceńskiej rzeki meandrującej lub anastomozyjącej. Po przerwaniu wału brzegowego przez wody powodziowe osady piaszczyste, pochodzące głównie z koryta rzeki oraz wałów brzegowych były deponowane na obszarze torfowiska w postaci stożków krewasowych. W efekcie, w pokładzie węgla brunatnego z odkrywki Tomisławice występują przewarstwienia klastyczne, co uniemożliwiało wykorzystanie znacznej jego części do celów energetycznych – zbyt wiele popiołu.My PhD thesis, submitted to the Scientific Council of the study of the Earth and the environment in fulfilment of the requirements for the degree of Doctor of Philosophy in the Faculty of Geographic and Geological Sciences (Adam Mickiewicz University), consists of four selected publications. My participation in their preparation is in the range of 35–100%, which was confirmed by the co-authors (statements of the co-authors). Two publications (the first and the second) are devoted to clastic sediments that form interbeds in the lignite seam. On the other hand, two subsequent publications (the third and the fourth) include studies of ash present within lignite. It just so happens that in the vicinity of Konin, only the first Mid-Polish lignite seam is currently exploited (2015-2021, research period). It is mined from three opencasts: Jóźwin IIB, Drzewce and Tomisławice. An important part of the research was fieldwork, including sedimentological studies. Moreover, numerous samples were taken from each opencast, both from clastic sediments and from the lignite seam. They were used for the following laboratory tests: grain-size analysis, ash content within lignite and determination of the chemical composition of the ash, that is, its elemental and oxide composition. As a result of mining activity of the Konin Lignite Mine (KWB Konin) in 2015-2016, between two lignite benches, siliciclastic sediments were uncovered in the Tomisławice opencast. They were lens-shaped, about 500 m long and up to 1.8 m thick, with a lignite layer up to 20 cm in the northern part of the exposure. They consisted mainly of fine-grained and well-sorted sands, with the exception of sediments in the top and basal parts, which were enriched with organic matter
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

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.
