ALIVE CEROPLASTICS 4D Representations
No full textInnovative uses of reliable non-destructive x-ray investigation technologies, applied to anatomical wax models, enabled the discovery of implementation methods used by master ceroplastics in seventeenth and eighteenth century, so making it possible to investigate the construction techniques of artistic works 'interior parts'.- We discovered master ceroplastics used human bones to build the ‘skeleton’ upon which they lay down specially prepared beeswax, molded at full mass technology, with different color pigments, so as to represent, in a real and admirable way, tendon structures, muscle and human body tissues. These radiological and tomographic investigation techniques have been combined with the latest generation of computer technologies, so to allow a virtual realization of the artifact generated by ceroplastics. It has also given them ‘life’ (4D virtual models ‘in motion’ realization). Virtual models, in fact, not only ‘move’, but 'open' to allow viewing of their internal constituent parts and 'dancing' with adequate and contemporary musical accompaniments.
- With all these virtual representations of anatomical wax, we don’t want in any way substitute the ceroplastics masters realizations, but constitute an additional tool that allows: (1) to increase the informations on anatomical waxes technical embodiments, aged and current; (2) to admit, for a wider diffusion and access, people to the anatomical waxes vision, even if placed at a considerable distance with respect to the original positioning place; (3) to enable the realization of de-localized exhibitions and events, allowing the viewer, the vision of actual artifacts in the place of the exhibition together with virtual artifact (moving!), placed in another physical location
Multi-layer spiral CT with 2D, 3D and 4D volume rendered electronic reconstructions of wax models and natural bone made by Giuseppe Astorri kept at “Luigi Cattaneo” Museum in Bologna
Full text linkThe “L. Cattaneo” Anatomy Museum wax anatomical models in Bologna, works of great historical, artistic and scientific value, have been used since the beginning of the 18th century for medical sciences students practical demonstrations. For this work, which aims to use innovative diagnostic investigation techniques for advancement either in education and scientific communication through a new “remote” method for the museum fruition, we used anatomical preparations and both normal human anatomical and pathological one wax models, from the dawn of the nineteenth according to the new Morgagni’s theories. We acquired a lot of high resolution photographs as many as tomographic images than processed using innovative representation techniques through new generation hardware equipment and an original software especially developed for full three-dimensional display. The several high-resolution photographs acquired around the object, combined with the results of the X-ray computed tomography (CT) investigation, show the 3D reconstruction of the object with their internal parts reassembled and, at the same time, reveal hidden structures and materials used, all in a non-invasive way. The CT analysis was performed using a specifically designed system, developed for application on Cultural Heritage at the Physics and Astronomy Department of Bologna University. The results of this work are shown through a virtual 3D projection using a device able to emulate a holographic representatio
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
