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
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
Analysis of MENA-4’s Textiles and Clothing Sector Competitiveness
No full textThis chapter looks at the relative competitiveness of the textile and clothing sector in the MENA-4 countries by analyzing trends and drivers of market shares. It also assesses the factors that directly affect cost competitiveness (cost of yarns and fabrics, production costs, market access costs and shipping costs) as well as the factors that indirectly affect competitiveness (lengthy import procedures, efficiency of customs and ports).
We examine outcome-based indicators of both international and domestic competitiveness. The former focuses on export performance, trends in market shares, and standard trade tools such as the constant market share analysis (CMS). The latter examines the domestic cost factors underlying performance and benchmarks MENA-4 against their major competitors in world markets
Impact of rehabilitation intervention on fatigue,endurance and physical function in patients withfibromyalgia : a case - control study
No full textBackground. Fibromyalgia (FM), a chronic condition typically
characterized by widespread pain, non restorative sleep, fatigue,
cognitive dysfunction and other somatic symptoms, negatively
impacts physical function. Rehabilitation is recommended in the
management of people with FM. To evaluate the rehabilitation impact
on fatigue, endurance and physical function at 6-month follow-up.
Methods. Forty-one FM patients (39 female, 2 male, mean age
52.2 ± 9.21 yrs), were randomized to an exercise and educationalbehavioural
programme group (Experimental Group, EG = 21) or
to a control group (GC=20). Both groups maintained their own
pharmacological therapy. Each subject was evaluated before, at the
end (T1) and after 6 months from the beginning of the rehabilitation
treatment using the Health Assessment Questionnaire (HAQ), the
Fatigue Severity Scale (FSS), the 6-Minute Walking Test (6MWT)
and a pocket goniometer (for spinal active range of motion). The
protocol included 20 sessions (twice a week) under physiotherapist’s
supervision, consisting in self-awareness, stretching, strengthening,
spine flexibility and aerobic exercises, which patients were educated
to perform at home.
Results. The 2 groups were comparable at baseline. On intergroup
comparison at T1, the EG showed improvement, although non
statistically significant (p between 0.221 – 0.502) in the HAQ and FSS
scales, and significant in the 6MWT and in most spinal active range of motion measurements (p between 0.001 – 0.04). The positive results achieved of the EG were maintained at the 6-month follow-up.
Conclusions. FM patients show excellent adherence to exercise
and an educational-behavioural programme with beneficial effects
on endurance, fatigue and physical function
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
