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
Techno-economic analysis of mobile battery storage systems to utilize curtailed wind energy in Germany for off-grid applications
No full textThe increasing share of renewable energy especially wind energy leads to increased share of unpredictable and varying energy into the grid. This leads to congestion in the grid which ultimately results in wind curtailment. In Germany in 2015 alone more than 4000 GWh of wind energy was curtailed. On the other hand, off grid energy requirements for event industry especially concerts and festivals, rely heavily on diesel generators to fulfill their power requirements. This thesis investigates a unique use case for the mobile storage application. The batteries are used to utilize the curtailed wind energy for off-grid applications like festivals and concerts in Germany. The batteries are charged at the wind farm during the duration of curtailment and once they are fully charged, the batteries are transported to the location of concert or an event to provide clean energy. The batteries or storage system used for this case have a capacity of 1.5 MWh and the whole system is constructed in a standard shipping container to allow convenient transportation. According to the findings of this study, the proposed use case can lead to a significant CO2 emission reduction, a single storage system could save up to about 8.4 million kg of CO2, at the events and festivals. Furthermore, it could help in renewable energy integration by providing clean wind energy, that is otherwise curtailed, to festivals and concerts. This study identifies a wind farm with most curtailed energy in Germany with total curtailment duration accounting for about 32% of the time in the year 2017. The technical model, simulated in MATALB/Simulink, successfully charged the battery storage system without any bottleneck. The levelized cost of storage was found to be in comparison with the levelized cost of diesel generators. A single storage system has an ability save up to 8.4 million kg of CO2 emissions. The study further proposes policy suggestions to promote such innovative use case.Den ökande andelen förnybar energi, särskilt vindenergi, leder en till ökad andel av oförutsägbar intermittent energi till elnätet. Detta leder tidvis till en överbelastning på elnätet, vilket resulterar i att vindkraftverkens elproduktion måste begränsas. Endast i Tyskland under 2015 begränsades 4000 GWh av vindenergi. Samtidigt används diesel generatorer i off-grid områden för att bedriva mässor, marknader, festivaler och liknande arrangemang. Den här rapporten undersöker ett specifikt fall för mobila lagringsmöjligheter. Batterier kan användas för att nyttja den begränsade vindenergin för offgrid evenemang som festivaler och konserter i Tyskland. Batterierna laddas i vindkraftsparker vid hög tillgång till vindenergi och transporteras sedan till ett evenemang för att försörjas med förnybar energi. Batterierna eller lagringsmediet som används för detta fall har en kapacitet på 1,5 MWh och systemet är paketerad i en fraktcontainer för enkel transport. Enligt resultaten från denna studie kan det föreslagna användningsfallet leda till en betydande minskning av koldioxidutsläppen, ett enda lagringssystem skulle kunna spara upp till cirka 8,4 miljoner kg CO2 vid evenemang och festivaler. Dessutom skulle det kunna bidra till integration av förnybar energi genom att tillhandahålla ren vindkraft, som annars begränsas, till festivaler och konserter. Denna studie identifierar en vindkraftspark med den mest begränsade energin i Tyskland med total kapacitetsvaraktighet som står för cirka 32% av tiden under 2017. Den tekniska modellen, simulerad i MATALB / Simulink, laddade batterilagringssystemet framgångsrikt utan flaskhals. De nivåiserade lagringskostnaderna visade sig vara i jämförelse med de nivåiserade kostnaderna för dieselgeneratorer. Ett enda lagringssystem kan spara upp till 8,4 miljoner kg koldioxidutsläpp. Studien föreslår vidare policyförslag för att främja ett sådant innovativt fall
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
