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
Roughness deterioration of bitumen sealed pavements
No full textPavement engineers have used road roughness as an indicator of a road’s functional performance for many years now. Generally, the roughness data has been viewed in terms of a pavement’s current absolute condition in which excessively rough roads will be earmarked for further engineering investigation and possible remedial works. Engineers have also attempted to predict the future roughness of their road network so that appropriate funding can be proactively assigned to maintain an acceptable level of service for road users. To undertake these future predictions a roughness progression model, or deterioration model, is used to increase the roughness of the pavement in proportion to its age and other parameters. Many deterioration models are available, however anecdotal evidence from practitioners indicated that the theoretical roughness progression provided by many models is rarely mimicked in real life. As such, a research project partnership was established between the Queensland Department of Main Roads and the Queensland University of Technology to investigate road roughness progression.\ud

This paper outlines the research effort undertaken in 2001 that reviewed the actual time-series roughness progression of approximately 16,000 individual pavement segments, each 1km in length. The research was undertaken using data from the Queensland Department of Main Roads’ database and spans between 4 and 14 years of roughness information. The technical challenges and resulting methodology of analysis of the time-series roughness data is discussed. The research also investigated the effects of pavement maintenance and reviewed many of the common variables such as age, soil type etc that are used in roughness prediction models. \ud
\ud
In 2003, the analysis was re-performed with three years of additional roughness data and revealed similar results to the 2001 research. Currently the Australian Road Research Board is investigating the use of roughness progression to assist in identifying under-performing pavements. Further improvements on the current methodology and future uses of actual pavement roughness progression are also discussed
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
Study of site-specific roughness progression for a bitumen-sealed unbound granular pavement network
No full textPavement management systems assist engineers in the analysis of road network pavement condition data, and subsequently provide input to the planning and prioritization of road infrastructure works programs. The data also provides input to a variety of engineering/economic analyses that assist in determining the future road network condition for a range of infrastructure funding scenarios. The fundamental calculation of future pavement condition is commonly based on a pavement age versus pavement roughness relationship. However, roughness/age relationships commonly do not take into account the pavement’s historic performance; rather, an ‘average’ rate of roughness progression is assigned to each pavement based on its current age or current roughness measurement. \ud
\ud
This paper documents the results of a research project that involved a comprehensive evaluation of pavement performance by examining roughness progression over time with other related variables. A method of calculating and effectively displaying roughness progression and the effects of pavement maintenance was developed, which provides a better understanding of pavement performance. This in turn led to a methodology of calculating and reporting road network performance, for application to the pavement design and delivery system within Queensland, Australia. Means of using this information to improve the accuracy of roughness progression prediction were also investigated
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
