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
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
Design to Control a Thermal Runaway in Battery Electric Vehicles (BEVs)
No full textThe rapid electrification of vehicles has neccessitated advancements in battery technology, impacting various components within the car battery pack. This project focuses on the development of thermal barriers, which serve as crucial components that prevent potential fires from thermal runaway incidents in the battery pack from reaching the vehicle's interior compartment. Currently, thermal barriers are predominantly composed of mica. The objective of this project is to identify a more sustainable alternative material to mica that possesses similar properties while considering economic, social, and environmental factors. Following the product development process, a comprehensive background study and benchmark analysis were conducted. Subsequently, the specific requirements for the new material were defined, and potential suppliers providing alternative materials were identified. Torch tests and dielectric strength tests were performed to assess thermal conductivity, fire resistance, and dielectric properties, which were deemed critical attributes. The test results unveiled a novel material comprised of a combination of two distinct materials from different suppliers. One material was a composite consisting of glass fiber and carbon, exhibiting exceptional thermal properties. The other material was an electrical-grade paper boasting excellent electrical properties. When combined, these materials formed a composite that paralleled the properties of mica. The composite material had a total thickness of 2 mm, slightly thicker than the current implementation of mica. To explore the feasibility of a thinner alternative, an estimation was conducted, suggesting that a thinner sheet of the composite material could be possible. In conclusion, this study demonstrates the feasibility of replacing mica with an alternative material. Further testing and investigation are required to determine the optimal implementation and minimum thickness of the new material. However, based on the successful test results and similarity in properties, it can be affirmed that the new material has the potential to replace mica as a sustainable thermal barrier in the battery pack.Denna avhandling fokuserar på utvecklingen av hållbara termiska barriärer som ersättning för mica i batteripacken i elektriska bilar, vilket har blivit nödvändigt på grund av den snabba elektrifieringen av fordon. Syftet med studien är att identifiera ett mer hållbart alternativ till mica och samtidigt ta hänsyn till ekonomiska, sociala och miljömässiga faktorer. Genom att följa produktutvecklingsprocessen har en omfattande bakgrundsstudie och benchmark-analys genomförts. Därefter definierades specifika krav för det nya materialet, och potentiella leverantörer av alternativa material identifierades. Väsentliga attribut som termisk ledningsförmåga, brandsäkerhet och elektriska egenskaper utvärderades genom att utföra flam-tester och tester för den elektriska ledningsförmågan. Resultaten av testerna resulterade i ett innovativt material bestående av en kombination av två olika material från olika leverantörer. En komposit av glasfiber och kol visade exceptionella termiska egenskaper, medan ett elektriskt kvalitetspapper uppvisade utmärkta elektriska egenskaper. När dessa material kombinerades bildade de en komposit som liknade micas egenskaper. Det komposita materialet hade en total tjocklek på 2 mm, något tjockare än mica. Genom en uppskattning undersöktes möjligheten att använda en tunnare variant av det komposita materialet. Sammanfattningsvis visar denna studie att det är genomförbart att ersätta mica med det föreslagna alternativa materialet. Vidare tester och undersökningar krävs för att optimera implementeringen och fastställa den minsta möjliga tjockleken på det nya materialet. Baserat på de positiva testresultaten och likheten i egenskaper kan det konstateras att det föreslagna materialet har potential att vara en hållbar termisk barriär i batteripaket

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
