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
Medo de quedas em indivíduos idosos hospitalizados com doença pulmonar obstrutiva crônica
No full textChronic obstructive pulmonary disease (COPD) leads to frequent
hospitalizations, associated with exacerbations and comorbidities. Individuals are
more likely to fall, which can lead to fear of falls and decreased physical activity. The
relationship between fear of falls and physical activity in hospitalized elderly people
with COPD is not well understood. Objectives: To verify the behavior of fear of falling
in hospitalized elderly individuals with COPD and its association with the level of
physical activity, activities of daily living (ADL), quality of life and symptoms of anxiety
and depression. Materials and Methods: Cross-sectional observational study with
hospitalized elderly individuals with COPD. Demographic and characterization data
were collected, followed by study evaluation. The Activities-specific Balance
Confidence (ABC), Falls Efficacy Scale – International (FES-I) and Short Falls Efficacy
Scale – International (Short FES-I) questionnaires were used to assess fear of falls.
Physical activity level was assessed by accelerometry using a triaxial accelerometer
(Actigraph wGT3X®). ADL was assessed by the London Chest Activity of Daily Living
(LCADL), while quality of life and symptoms of anxiety and depression were assessed
by the EuroQuol five dimensions (EQ-5D) and Hospital Anxiety and Depression Scale
(HADS) questionnaires, respectively. Lower limb strength and functionality were
assessed by the 60-second Sit-to-Stand Test (SST 60s) and postural balance by the
Mini Balance Evaluation Systems Test (MiniBESTest). Univariate and multiple
regression analyses were performed to identify associations and predictors of fear of
falling. P < 0.05 was considered significant. Results: Twenty-three individuals were
included (mean ± SD; age 71.6 ± 7.2 years, FEV1 ± 52.5 ± 22.1% pred). The mean
ABC score was 69.2 ± 27.8, with a moderate fear of falling in the FES-I and Short FESI (27.2 ± 10.4 and 11 ± 4.84 points respectively). Fear of falling in the Short FES-I was
associated with greater sedentary behavior (R²= 0.924; p= 0.039). In the ABC, fear of
falling was associated with the "sensory orientation" domain of the Mini BESTest, after
adjustment for length of hospital stay (R²= 0.502; p= 0.037). In the FES-I, the degree
of dyspnea (R²= 0.620; p= 0.010) and the "total" (R²= 0.552; p= 0.006), "domestic
activities" (R²= 0.408; p= 0.014) and "leisure activities" (R²= 0.484; p= 0.013) domains
of ADL remained significant after adjustment for comorbidities. In the Short FES-I, the
degree of dyspnea and the "total" and "leisure activities" domains of ADL remained
significant after adjustment for comorbidities. The predictors for fear of falls were
dyspnea, ADL, lower limb strength and functionality, and postural balance.
Conclusion: Hospitalized elderly individuals with COPD have a moderate fear of falls,
associated with greater sedentary behavior, worse postural balance, greater dyspnea,
and negative impact on ADL. Dyspnea, ADL, lower limb strength and functionality, and
postural balance may be predictors for fear of falls, with comorbidities and length of
hospital stay influencing these relationships.A doença pulmonar obstrutiva crônica (DPOC) leva a hospitalizações
frequentes, associadas a exacerbações e comorbidades. Os indivíduos apresentam
maiores chances de cair, podendo levar ao medo de quedas e diminuição da atividade
física. A relação entre o medo de quedas e atividade física em idosos com DPOC
hospitalizados não é bem compreendida. Objetivos: Verificar o comportamento do
medo de quedas de indivíduos idosos com DPOC hospitalizados e a sua associação
com o nível de atividade física, atividade de vida diária (AVD), qualidade de vida e
sintomas de ansiedade e depressão. Materiais e Métodos: Estudo observacional
transversal com idosos com DPOC hospitalizados. Foram coletados dados
demográficos e de caracterização, seguidas pela avaliação do estudo. A Activitiesspecific Balance Confidence (ABC), e os questionários Falls Efficacy Scale –
International (FES-I) e Short Falls Efficacy Scale – International (Short FES-I) foram
usados para avaliar o medo de quedas. O nível de atividade física foi avaliado por
acelerometria, utilizando um acelerômetro triaxial (Actigraph wGT3X®). A AVD foi
avaliada pelo London Chest Activity of Daily Living (LCADL), enquanto qualidade de
vida e sintomas de ansiedade e depressão foram avaliados pelos questionários
EuroQuol five dimensions (EQ-5D) e Hospital Anxiety and Depression Scale (HADS),
respectivamente. A força e funcionalidade dos membros inferiores foi avaliada pelo
Teste de Sentar e Levantar em 60 segundos (TSL 60s) e o equilíbrio postural pelo
Mini Balance Evaluation Systems Test (MiniBESTest). Análises de regressão
univariada e múltipla foram realizadas para identificar associações e os preditores do
medo de quedas. Considerou-se significante p < 0,05. Resultados: Foram incluídos
23 indivíduos (média ± DP; idade 71,6 ± 7,2 anos, VEF1 ± 52,5 ± 22,1% pred). A média
da pontuação na ABC foi 69,2 ± 27,8, com um moderado medo de quedas no FES-I e
Short FES-I (27,2 ± 10,4 e 11 ± 4,84 pontos respectivamente). O medo de quedas na
Short FES-I foi associado a maior comportamento sedentário (R²= 0.924; p= 0.039).
Na ABC, o medo de quedas se associou ao domínio "orientação sensorial" do Mini
BESTest, após ajuste pelo tempo de internação (R²= 0.502; p= 0.037). No FES-I, o
grau de dispneia (R²= 0.620; p= 0.010) e os domínios "total" (R²= 0.552; p= 0.006),
"atividades domésticas" (R²= 0.408; p= 0.014) e "atividades de lazer" (R²= 0.484; p=
0.013) da AVD permaneceram significativos após ajuste por comorbidades. Na Short
FES-I, o grau de dispneia e os domínios "total" e "atividades de lazer" das AVD
mantiveram significância após ajuste por comorbidades. Os preditores para o medo
de quedas foram dispneia, AVD, força e funcionalidade de membros inferiores e
equilíbrio postural. Conclusão: Idosos com DPOC hospitalizados possuem moderado
medo de quedas, associado a maior comportamento sedentário, pior equilíbrio
postural, maior dispneia e impacto negativo na AVD. Dispneia, AVD, força e
funcionalidade de membros inferiores e equilíbrio postural podem ser preditores para
o medo de quedas, com comorbidades e tempo de internação influenciando essas
relações
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

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.
