Modelling the Aboriginal rock art of Mt Moffat\ud
No full textThis paper introduces the method used to produce a 3D model of an Aboriginal Rock Art Cave for inclusion in a synthetic environment using the Torque game engine as its user interface. The site chosen for this is an area called “The Tombs” in the Mt Moffat section of the Carnavon Gorges National Park. The game developers were facing a number of obstacles such as remoteness of the site, its accessibility and the necessity to produce a 3D model with a low number of polygons for an efficient use in Virtual Reality.\ud
Given the nature of the model to construct, a traditional method of surveying/modelling would have produced a very high number of polygons making it necessary for a lengthy process of optimization. Laser scanning or Photogrammetry would produce the most accurate data collection but would have been difficult due to the presence of numerous trees; and, because little was known about the site, the choice of appropriate equipment was difficult to make and not practical to carry into the remote of the site. The geometrical accuracy was not a priority, as the purpose of the model is for visualisation alone, therefore a much simpler method of surveying and modelling was chosen.\ud
A series of high resolution photographs were taken onsite. These were used as a base for the mesh modelling as well as for the texturing of the final result. Each photo was then calibrated before stitching to produce a panorama of the entire rock face. The panorama was then used as a texture onto a flat plane made of 500 polygons. The most obvious cracks and recesses were then created by changing the Z value of the relevant polygons, finally the high resolution panorama was re-applied to form the final texture. The entire process took approximately 16 hours and the end result is a very realistic mesh model with less than 1000 polygons. This paper will report on the processes and outcomes of this project in the context of preserving and enhancing aboriginal cultural heritage
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
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
