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
Evaluación de grados de calidad y rendimiento de la canal en vaquillas reimplantadas con cinco anabólicos sesenta días antes del sacrificio.
No full text"El presente trabajo se llevó a cabo con el objeto de evaluar los grados de calidad y rendimiento de la canal de vaquillas reimplantadas con cinco anabólicos sesenta días antes del sacrificio
Se utilizaron 113 vaquillas de 10 meses de edad de razas productoras de carne y con un peso vivo promedio
de 287 kg, distribuídas en seis tratamientos bajo un
diseño completamente al azar con diferente número de repeticiones. Los tratamientos designados fueron: grupo 1, sin implante con 18 animales; grupo 2, con 200 mg de acetato de trembolona (ATB) mas 28 mg de benzoato de estradiol (ATB200+BES28) con 18 animales; grupo 3, con 140 mg de acetato de trembolona mas 20 mg de 17 S estradiol (ATB140+17SES20) con 18 animales; grupo 4, con 200 mg de propionato de testosterona mas 20 mg de benzoato de estradiol (TES200+BES20) con 20 animales; grupo 5, con 200 mg de acetato de trembolona mas 20 mg de 17 II estradiol (ATB200+17SES20) con 19 vaquillas y grupo 6 con 36 mg de
zeranol con 20 animales. Para las características de
grados de calidad y rendimiento de la canal se evaluó a cada animal como una repetición. Se evaluó el grado de marmoleo y grado de calidad, grado de rendimiento, peso de la canal caliente, grasa de cobertura, grasa en riñón, pelvis y corazón (RPC) y área del ojo de la costilla. En el grado de marmoleo y calidad no existió diferencia estadística significativa entre tratamientos, aunque se observó que los tratamientos de implantes tendieron a disminuir el grado de marmoleo y calidad de la canal. El peso de la canal caliente fue muy similar para todos los tratamientos, no existiendo diferencia estadística significativa entre tratamientos. En el área del ojo de la costilla no existió diferencia estadística significativa entre tratamientos, pero se observó que entre tratamientos
de implantes los de actividad androgénica (2, 3, 4 y 5) tuvieron una mayor área que zeranol. La grasa de cobertura fue mayor en el grupo sin implante que en los tratamientos de implantes,. aunque no existió diferencia estadística significativa entre tratamientos. En la grasa RPC el grupo con zeranol obtuvo el valor más alto (2.2 por ciento). En el grado de rendimiento de la canal no existieron diferencias estadísticas entre tratamientos (P>0.05). Se observó que los implantes con ATB mas 17 E. estradiol y TES200+BES20 tendieron a mejorar el grado de rendimiento
de la canal. Para los incrementos de peso diario,
ATB200+17SES20 fue el más alto (1.212 kg/d), seguido por ATB140+1713ES20 (1.102 kg/d) y ATB200+BES28 (1.040 kg/d). TES200+BES20 y zeranol fueron inferiores en incrementos diarios de peso y muy similares al tratamiento sin implante. De la información obtenida se concluye que el efecto de los implantes anabólicos aplicados a vaquillas 60 días antes del sacrificio no influye en forma significativa los grados de calidad y rendimiento de la canal; sin embargo, existió la tendencia a mejorar los incrementos de peso diario; donde los implantes con ATB más estradiol tendieron a mejorar el incremento diario de peso en vaquillas en un período de finalización de 60 días antes del sacrificio disminuyendo así los días necesarios para su finalización y sacrificio.""A trial was conducted to evaluate carcass quality and yield grade of heifers implanted with five anabolics 60 days before slaughter.
One hundred and thirteen animals were used of different breeds within a commercial feedlot with an
average initial weight of 287 kg distribuited randomly within 6 inequal treatments.
Treatments were: group 1 with 18 animals without implant; group 2 with 18 animals with 200 mg of trenbolone
acetate (ATB) plus 28 mg of estradiol benzoato
(ATB200+BES28); group 3 with 18 animals wit 140 mg of ATB plus 20 mg of estradiol 17 13 (ATB140+17SES20); group 4 with 20 animals with 200 mg of testosterone plus 20 mg of estradiol benzoato (TES200+BES20); group 5 with 19 animals with 200 mg of ATB plus 20 mg of estradiol 17 i3 (ATB200+17SES20); and group 6 with 20 animals and 36 mg of zeranol.
Carcass quality and yield grade was evaluated in each animal within treatment. Hot carcass weight, fat tickness, kidney, pelvic and heart fat (KPH), ribeye area, were measured in each carcass for to take yield grade. Were no significant difference (P>0.05) in marbling and quality degree between treatments, althougt there was a tendency to implants to decrease marbling and carcass quality. Hot carcass weight was simmilar for all treatments (P>0.05). Fat tickness, KPH, ribeye area, and yield grade were simmilar for all treatments (P>0.05). For average daily gain there was no statistical comparison; neverthless there was a tendency for treatments ATB200+171ES20, ATB140+170ES20 and ATB200+BES28 to be better than treatments control, TES200+BES20 and zeranol group. It was concluded than the effect anabolics implants did not influence significatively in 60 days before slugther in
carcass quality and yield grade; neverthless there was a tendency for average daily gain to be better with implants with ATB respect to other treatments (Control group, zeranol and TES200+BES20).
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

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.
