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
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
Multichannel temperature measurement for the KETCube platform
No full textPředkládaná bakalářská práce se ve své úvodní teoretické části krátce zabývá měřenými veličinami (teplota, vlhkost) na což navazuje poměrně rozsáhlý popis využívaných technologií, platformy KETCube a přehled dostupných komponentů pro návrh rozšiřujících desek. V praktické části je popis vytvořených desek plošných spojů s vyspecifikovanými součástkami pro jejich realizaci.ObhájenoThe submitted bachelor thesis in its introductory part shortly deals with measured values (temperature, humidity), followed by a relatively extensive description of the used technologies, KETCube platform and an overview of available components for the design and proposal of expansion boards. In the practical part is a description of created PCB with specified electronic components
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
Battery monitoring for IoT devices
No full textDiplomová práce se zabývá problematikou monitorování zbývající energie zejména v primárních článcích na bázi Lithium-Thionylchloridu (Li-SOCl2), které nachází své uplatnění v nízkoenergetických IoT zařízeních. Účelem této práce je výběr a validace vhodných integrovaných obvodů pro aplikační nasazení do této oblasti. V teoretické části se nejprve zaměříme na úvod do povědomí o Internetu věcí (IoT) a zde využívaných bezdrátových sítí. Jako příklad nízkoenergetického IoT zařízení je v práci uvedena a popsána platforma KETCube. Dále je zde zpracován popis primárních baterií a využitelné metody pro získání informací o zbývající energii a kapacitě. V rámci uceleného přehledu zde zmíníme také Energy harvesting. Praktická část práce je věnována návrhu a realizaci desek plošných spojů pro rešeršované integrované obvody. Pro veškeré vytvořené elektronické obvody je následně provedeno měření s vyhodnocením získaných výsledků.ObhájenoThe thesis deals with the issue of monitoring the remaining energy, especially in primary cells based on Lithium-Thionyl Chloride (Li-SOCl2), which find their application in low-power IoT devices. The purpose of this work is to select and validate suitable integrated circuits for application deployment in this area. In the theoretical part, we first focus on an introduction to the Internet of Things (IoT) and the wireless networks used here. As an example of a low-power IoT device, the KETCube platform is presented and described in this thesis. Furthermore, a description of primary batteries and usable methods for obtaining information about the remaining energy and capacity are elaborated. As part of a comprehensive overview, Energy harvesting is also mentioned here. The practical part of the thesis is devoted to the design and implementation of printed circuit boards for the researched integrated circuits. For all the designed electronic circuits, measurements are subsequently performed with evaluation of the obtained results
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
