Ultrasound System Typologies, User Interfaces and Probes Design: A Review
Full text linkAbstractThe present review paper aims to give insights regarding what is available now, and will be in the next future, on the Market in terms of Ultrasound (US) system User Interfaces characteristics and peculiarities; US system typologies and probe typologies. Moreover, insights regarding ergonomics evaluation technologies and techniques for US systems, User Interface and transducers design evaluation, will be provided as well. The User interface ergonomics of US systems and probes is of primary importance due to the increased use in the everyday clinical practice even by non-sonographers, and the higher attention to the Work-related Musculoskeletal Disorders (WRMSD). A large overview and review of market data, side by side tests, websites, interviews to US users, marketing and sales professionals, scientific and educational publications was carried out in order to collect all available data as well as to show and describe them to the reader. Nowadays US market offers many different typologies of systems and probes, with different prices, features, quality level and targets of use. Users have to be aware to increase their level of knowledge in order to perform the best choice in terms of price/performance ratio and in terms of ergonomics and workflow requirements. The same level of knowledge is necessary also for other stakeholders of the US imaging Lab and purchasing/test decision phases such as Clinical and Biomedical Engineers involved in technical decision related to capital equipment and their maintenance. Final users expect technical innovations every 6-12 months in order to ensure technical-clinical improvements and company commitment to research and customer focus. Such characteristics are important clues showing a fast moving of the US market from a capital equipment basis to a more mass-consumer approach characterized by fast innovations, quick obsolescence and consumer prone attitude to system rotation in order to have always the more up-to-date technology, product, probe available on the Market
Ergonomic Design Process of the Shape of a Diagnostic Ultrasound Probe
No full textThis study presents a design process for the ergonomic design of a hockey stick ultrasound probe, based on clinical applications needs, competitors benchmarking and analysis of feedback about a commercially available probe. The design is performed in two phases: (1) design of the product and initial evaluation of subjective satisfaction of expert users; (2) the subsequent review of the project and the selection of the preferred probe grip design. This approach involves several successive stages allowing for progressively better results in terms of acceptability and comfort of the new product

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
