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
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
The Devon Active Villages Evaluation (DAVE) Trial of a Community-level Physical Activity Intervention in Rural South-West England: A Stepped Wedge Cluster Randomised Controlled Trial
No full textBackground: Although physical inactivity has been linked with numerous chronic health conditions and overall mortality, the majority of English adults report insufficient physical activity. To increase population physical activity levels, researchers have called for more community-level interventions. To evaluate these complex public health interventions, innovative study designs are required. The aim of this thesis was to evaluate whether a community-level physical activity intervention—‘Devon Active Villages’—increased the activity levels of rural communities.
Methods: The Devon Active Villages intervention provided villages with 12 weeks of physical activity opportunities for all age groups. Community engagement helped tailor activity programmes for each village; communities were then supported for a further 12 months. 128 rural villages from south-west England were randomised to receive the intervention in one of four time periods, as part of a stepped wedge cluster randomised controlled trial. Data collection consisted of a postal survey of a random sample of adults (≥18 years), at baseline, and after each of the four intervention periods. The primary outcome of interest was the proportion of adults who reported sufficient physical activity to meet the current guidelines (≥150mins of moderate-and-vigorous, or ≥75mins of vigorous-intensity activity per week). The number of minutes spent in moderate-and-vigorous activity per week was analysed as a secondary outcome. Using data from all five periods, a comparison of study outcomes between intervention and control arms was performed, allowing for time period (as a fixed effect), and the random effect induced by correlation of outcomes (clustering) within villages. Additionally, the baseline data were analysed separately using logistic and linear regression models to examine the correlates of physical activity behaviour in rural adults.
Results: Baseline study: 2415 adults completed the postal survey (response rate 37.7%). The following factors both increased the odds of meeting the recommended activity guidelines and were associated with more leisure-time physical activity: being male, in good health, greater commitment to being more active, favourable activity social norms, greater physical activity habit, and recent use of recreational facilities. In addition, there was evidence that younger age, lower body mass index, having a physical occupation, dog ownership, inconvenience of public transport, and using recreational facilities outside the local village were associated with greater reported leisure-time physical activity.
Main study: 10,412 adults (4693 intervention, 5719 control) completed the postal survey (response rate 32.2%). The intervention did not increase the odds of adults meeting the physical activity guideline, although there was weak evidence of an increase in the minutes of moderate-and-vigorous-intensity activity per week. The ineffectiveness of the intervention may have been due to its low penetration—only 16% of intervention participants reported being aware of the intervention, and just 4% reported participating in intervention events.
Conclusions: Baseline study: This study highlights potentially important correlates of physical activity that could be the focus of interventions targeting rural populations, and demonstrates the need to examine rural adults separately from their urban counterparts.
Main study: A community-level physical activity intervention providing tailored physical activity opportunities to rural villages did not improve physical activity levels in adults. Greater penetration of such interventions needs to be achieved for them to have any chance of increasing the prevalence of physical activity at the community level.Economic and Social Research Counci
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
