Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
QuickTrust : Produktförnyelse av vakuumassisterad biopsinålhållare med tillhörande adapter
No full textThis bachelor ́s thesis was conducted in collaboration with Turon Medtech AB and aimed to innovate and improve a vacuum-assisted biopsy (VAB) needle holder and its corresponding adapter. These components are used to mount a vacuum-assisted biopsy needle during breast biopsy procedures. The goal was to improve usability for healthcare professionals and enhance patient comfort by further developing the company ́s existing needle holder and adapter. The development process was carried out through an iterative design process, beginning with a needs identification phase based on work analysis in a clinical setting. This was followed by the creating of a requirement specification and conceptual design phase, where analogy modeling was used as a supporting tool. The generated concepts were systematically evaluated using the Pugh matrix and expert opinions from clinical professionals and mechanical engineers. Several plastic prototypes were manufactured in plastic to enable practical testing and further development. In the final design stage, aluminum 7075-T6 along with a surface treatment of 20 natural anodizing was selected as the material for the final product, and the solution was verified through a Finite Element Method (FEM) analysis. The solution developed in this bachelor ́s thesis was named QuickTrust, a mechanical locking device consisting of a VAB-needle holder, an adapter, and two removable locking arms. The design enables quick and secure one-handed assembly and disassembly, along with locking indicators that ensure correct position during biopsy. The modular design in aluminum 7075-T6 along with a surface treatment is optimized for efficient cleaning and withstands the expected mechanical loads. The bachelor ́s thesis thus presents a technically verified design solution with the potential to improve workflow, increase patient safety, and enhance both user and patient experience during breast biopsy procedures. Kandidatuppsatsen gjordes i samarbete med företaget Turon Medtech AB och syftade till att produktförnya en vakuumassisterad biopsi (VAB) nålhållare och en tillhörande adapter. Dessa används för att montera en vakuumassisterad biopsinål vid bröstbiopsier. Målet var att förbättra användarvänligheten för vårdpersonal samt öka patientkomforten genom att vidareutveckla företagets befintliga VAB- nålhållare och tillhörande adapter. Utvecklingsarbetet bedrevs genom en iterativ designprocess som inleddes med behovsidentifiering baserad på arbetsanalys inom klinisk miljö. Därefter togs en kravspecifikation fram, följt av konceptuell utformning där analogimodellering användes som stöd. De framtagna koncepten utvärderades systematiskt med hjälp av Pugh-matris och expertutlåtanden från både klinisk expertis och konstruktörer. Flera prototyper tillverkades i plast för att möjliggöra praktisk testning och vidareutveckling. I det avslutade konstruktionsarbetet valdes aluminium 7075-T6 ytbehandlat med 20 naturlig anodisering som material för den färdiga produkten, lösningen verifierades genom en Finita Elementmetod (FEM) analys. Lösningen som utvecklades i kandidatuppsatsen namngavs QuickTrust, en mekanisk låsanordning bestående av en VAB-nålhållare, en adapter och två avtagbara låsarmar. Konstruktionen möjliggör snabb och säker montering och demontering med enhandsfattning samt tydliga låsindikatorer som säkerställer korrekt positionering vid biopsi. Den modulära designen i aluminium 7075-T6 med ytbehandlig är anpassad för effektiv rengöring och de förväntade mekaniska påfrestningarna. Kandidatuppsatsen presenterar därmed en tekniskt verifierad designlösning med potential att förbättra arbetsflöden, öka patientsäkerheten och höja både användar- och patientupplevelsen vid bröstbiopsier.
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
