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
Avaliação dos efeitos clínicos e sedativos da dexmedetomidina intramuscular, subcutânea e no acuponto yin tang em bezerros
No full textα-2 adrenergic agonists are the main sedatives used in ruminant medicine, and dexmedetomidine is
described as the most selective and safe among the drugs in this group. Pharmacopuncture has become
an alternative in sedation protocols for large animals, since it aims through subdoses to achieve a similar
effect of the conventional dose of the drug and the reduction of undesirable effects. Thus, the present
study aimed to evaluate the clinical and sedative effects of dexmedetomidine intramuscularly,
subcutaneously and in the Yin Tang acupoint in calves. For this, six animals were used, three males and
three females of the girolando breed, submitted to three experimental protocols: intramuscular
dexmedetomidine at a dose of 4µg/kg (DEX-IM); subcutaneous dexmedetomidine at a dose of 0.4µg/kg
(DEX-SC) and dexmedetomidine in the Yin Tang acupoint also at a dose of 0.4µg/kg (DEX-YT).
Parameters were evaluated at baseline (M0) and every 20 minutes thereafter (M20, M40, onwards),
respiratory rate (f), heart rate (HR), systolic blood pressure (SBP), temperature rectal (TR), ruminal
movements (RM), hematocrit (HT), glycemia (GL) and degree of sedation. Data were submitted to
analysis and statistics. The f remained stable in the DEX-YT group, and showed a tendency to decrease
in the DEX-IM and DEX-SC groups, however there was no statistical difference between the times in
the three groups. SBP showed no statistical difference between the groups or over time, however, it
showed a tendency to increase in the DEX-IM group. HR decreased in the DEX-IM group, while in the
DEX-SC and DEX-YT groups it remained stable. RM decreased in the DEX-IM group, which did not
occur in the DEX-SC and DEX-YT groups. HT and TR showed no statistical difference between groups
or over time. GL showed a significant increase in the DEX-IM group, however, in the DEX-SC and
DEX-YT groups there was no increase. Regarding the degree of sedation, only the animals in the DEX IM group showed behavioral changes that lasted for up to 120 minutes. Dexmedetomidine, at a dose of
4µg/kg administered by the intramuscular route, causes moderate sedation in dairy calves for up to 120
minutes, without presenting clinical complications. The dose of 0.4 μg/kg administered subcutaneously
and in the Yin Tang acupoint did not promote sedation in these animals. The dose of 4µg/kg of
dexmedetomidine may be indicated for short-term procedures in healthy animals.Os agonistas α-2 adrenérgicos são os principais sedativos utilizados na medicina de ruminantes, e a
dexmedetomidina é descrita como a mais seletiva e segura entre os fármacos desse grupo. A
farmacopuntura tem se tornado uma alternativa em protocolos de sedação de grandes animais, já que
visa através de subdoses alcançar efeito semelhante da dose convencional do fármaco e a diminuição
dos efeitos indesejáveis. Dessa forma, o presente trabalho objetivou avaliar os efeitos clínicos e
sedativos da dexmedetomidina pelas vias intramuscular, subcutânea e no acuponto Yin Tang em
bezerros. Para tal, foram utilizados seis animais, sendo três machos e três fêmeas da raça girolando,
submetidos a três protocolos experimentais: dexmedetomidina intramuscular na dose de 4µg/kg (DEX IM); dexmedetomidina subcutânea na dose de 0,4µg/kg (DEX-SC) e dexmedetomidina no acuponto Yin
Tang também na dose de 0,4µg/kg (DEX-YT). A avaliação dos parâmetros ocorreu no momento basal
(M0) e a partir daí a cada 20 minutos (M20, M40, em diante), sendo avaliados frequência respiratória
(f), frequência cardíaca (FC), pressão arterial sistólica (PAS), temperatura retal (TR), movimentos
ruminais (MR), hematócrito (HT), glicemia (GL) e grau de sedação. Os dados foram submetidos à
análise e estatística. A f se manteve estável no grupo DEX-YT, e apresentou uma tendência a diminuição
nos grupos DEX-IM e DEX-SC, no entanto sem diferença estatística entre os tempos nos três grupos. A
PAS não apresentou diferença estatística entre os grupos nem ao longo do tempo, contudo, apresentou
uma tendência ao aumento no grupo DEX-IM. A FC diminuiu no grupo DEX-IM, enquanto nos grupos
DEX-SC e DEX-YT se manteve estável. Os MR diminuíram no grupo DEX-IM, o que não ocorreu nos
grupos DEX-SC e DEX-YT. HT e TR não apresentaram diferença estatística entre os grupos e nem ao
longo do tempo. A GL apresentou um aumento significativo no grupo DEX-IM, no entanto, nos grupos
DEX-SC e DEX-YT não houve aumento. Quanto ao grau de sedação, apenas os animais do grupo DEX IM apresentaram mudanças comportamentais que perduraram por até 120 minutos. A dexmedetomidina,
na dose de 4µg/kg administrada pela via intramuscular causa sedação moderada em bezerros de leite
por até 120 minutos, sem apresentar complicações clínicas. Já a dose de 0,4 μg/kg administrada pela via
subcutânea e no acuponto Yin Tang não promoveu sedação nesses animais. A dose de 4µg/kg da
dexmedetomidina pode ser indicada para procedimentos de curta duração em animais hígidos
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.
