No full textGoing 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
Active preservation of analogue audio documents: A summary of the last seven years of digitization at CSC
No full textDuring the last 40 years, a large number of musical works was composed and recorded at the Centro di Sonologia Computazionale (CSC) of the University of Padova. The problem of how to preserve this increasing amount of audio documents arose and, in order to meet this need, the CSC started to carry out a research to develop a scientific methodology for preservation. In the last 7 years, this methodology was refined and applied to the digitization of more than 2,500 audio documents both from Italian and international audio archives, mainly stored on analogue magnetic carriers such as open-reel tapes and cassettes. Their content consists of electronic, folk and other kinds of music, as well as speech recordings. The methodology provides for collecting numerous metadata about the original carrier on which the audio information was stored, i.e. flange diameter, brand and material, its physical state and the related preservation copy, necessary for a correct preservation of the content and the contextual information. This work aims to extract and interpret the information from this wealth of data and metadata, which was collected and structured through the software PSKit. This may be useful for audio technicians, archives and policy makers to plan future preservation projects
Three-Dimensional Experimental Analysis of Wear in Retrieved Hip Implants
No full textWear is recognized as one of the main causes of hip replacement failure, as it can lead to instability, pain, and revision surgeries. Consequently, numerical and experimental wear investigations on hip implants are highly relevant in biomedical and orthopedic research. This study is focused on the application of advanced experimental analyses for wear characterization of hip replacements and presents an innovative and dedicated experimental wear assessment protocol based on 3D scanners. The method was tested on retrieved metal-on-plastic hip implants and provided 3D wear maps of the damaged surfaces of both the cup and head. Some preliminary results obtained on a plastic cup are here presented and discussed. The primary goal of these analyses is to understand the causes and mechanisms of wear so that prosthetic materials and designs can be improved, implant reliability, and patients’ quality of life enhanced. The research activity presented in this paper promotes more responsible production and consumption, making the biomedical sector more sustainable and resilient over time. Therefore, it contributes directly to the goals of sustainable development by improving health and well-being (SDG3), promoting technological innovation and reducing environmental impact (SDG9 and SDG12) with a reduction of material wastage and favoring recycling and waste management, improving collaboration between universities, research centers, biomedical industries, and hospitals (SDG17)
