    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 PDF
    We 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 PDF
    We 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

    Natural history of Emerita analoga (Stimpson) (Anomura, Hippidae) in a sandy beach of Northern Chile

    No full text
    Sediment samplings were carried across the intertidal of the beach at Hornitos, northern Chile (22 degrees 26'S) during August and November 1996 and March, July and November 1997 for a study of the reproductive and population biology of Emerita analoga (Stimpson) (Decapoda, Anomura) in a region of the Chilean coast characterized by persistent upwelling. The highest abundances of E. analoga occurred during March and December 1997. During November 1996, March and December 1997, the highest abundances occurred below the effluent line, while in July 1996 and August 1997, most of the stages of E. analoga occurred in higher abundances above the effluent line. Ovigerous females were recorded over the entire study period. Juveniles were also present during all sampling months, peaking during March 1997. Body size of ovigerous females varied between 12.6 and 26.4 mm. Fecundity increased significantly with body size of females in all samples analyzed. The analyses of recruitment pattern for males and females suggest the existence of two pulses in the recruitment of E. analoga at Hornitos: one between October and December, and another one between February and March. Growth analyses show that females have growth rates a maximum body sizes higher than males. Comparisons with similar studies carried out at the coast of south central Chile (ca. 39 degreesS), a region where upwelling occurs occasionally, show that E. analoga from this region have similar growth rates but attain a greater maximum body size than in Hornitos. It is concluded that proximity to areas of persistent upwelling seems not to affect life history of E. analoga in northern Chile.PT: J; CR: ABELE LG, 1982, BIOL CRUSTACEA, V1, P241 ARNTZ WE, 1987, POPULATION COMMUNITY, P645 AVELLANAL MH, IN PRESS REPROD CYCL BERTALANFFY LV, 1938, HUM BIOL, V10, P181 BOSMAN AL, 1987, OECOLOGIA, V72, P226 BRUSCA RC, 1979, B BIOL SOC WASH, V3, P67 CONAN G, 1975, 10 EUR S MAR BIOL, V2, P129 CONTRERAS H, 1999, ESTUAR COAST SHELF S, V48, P101 COX GW, 1968, ECOLOGY, V49, P746 DIAZ H, 1983, MAR ECOL-PROG SER, V10, P203 DUGAN J, 1994, J EXPT MARINE BIOL E, V181, P225 DUGAN JE, 1991, J EXP MAR BIOL ECOL, V150, P63 DUGAN JE, 1996, REV CHIL HIST NAT, V69, P579 EFFORD IE, 1965, J ANIM ECOL, V34, P63 EMERY KO, 1938, J SEDIMENT PETROL, V8, P105 EMERY KO, 1961, LIMNOL OCEANOGR, V6, P90 FOLK R, 1980, PETROLOGY SEDIMENTAR FONSECA T, 1987, INVEST PESQ, V34, P33 FUSARO C, 1978, FISHERY B, V76, P369 GAYANILO FC, 1989, ICLARM CONTRIBUTION, V435 GAYANILO FCJ, 1996, FAO COMPUTERIZED INF, V8 GIBBS RJ, 1971, J SEDIMENT PETROL, V41, P7 HOENIG JM, 1982, STAT STUDY SEASONAL JARAMILLO E, 1987, THESIS U NEW HAMPSHI JARAMILLO E, 1993, MAR ECOL-PROG SER, V101, P105 JARAMILLO E, 1994, S AFR J ZOOL, V29, P227 JARAMILLO E, 1998, REV CHIL HIST NAT, V71, P459 JOHNSON MW, 1939, J MAR RES, V2, P236 KNOX C, 1963, B SO CALIFORNIA ACAD, V62, P45 MACGINITIE GE, 1938, AM MIDL NAT, V19, P471 MARIN V, 1993, REV CHIL HIST NAT, V66, P479 MCARDLE SB, 1992, J COASTAL RES, V8, P398 MORENO CA, 1998, MAR ECOL-PROG SER, V167, P171 OSORIO C, 1967, B MUSEO NACL HIST, V29, P60 PAULY D, 1984, FISHBYTE, V2, P21 PAULY D, 1984, PENAEID SHRIMPS THEI, P220 PAULY D, 1985, NAFO SCI COUN STUD, V9, P143 PAULY D, 1990, FISHBYTE, V8, P33 PENCHASZADEH P, 1971, I BIOL MARINA OFICIN, V6, P1 SEWARDTHOMPSON B, 1973, SEDIMENTOLOGY, V11, P83 SHORT AD, 1983, SANDY BEACHES ECOSYS, P133 SOKAL RR, 1995, BIOMETRY PRINCIPLES SOMERS IF, 1988, FISHBYTE, V6, P8 SPARRE P, 1989, FAO FISHERIES TECHNI, V306, P1 SPARRE P, 1989, FISHBYTE, V7, P23 SPARRE P, 1990, FISHBYTE, V8, P29 TARAZONA J, 1988, J MAR RES, V46, P593 TEMPLEMAN W, 1936, J BIOL BOARD CANNADI, V2, P42 VAKILY JM, 1990, THESIS CHRISTIAN ALB WOLFF M, 1989, FISHBYTE, V7, P5; NR: 50; TC: 3; J9: REV CHIL HIST NAT; PG: 11; GA: 396ZUSource type: Electronic(1

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We 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 text
    In 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.
