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
High-speed jets and related phenomena at Earth's bow shock and magnetosheath
No full textMagnetosheath high-speed jets are transient and localized dynamic pressure enhancements downstream of Earth’s bow shock. Their formation has been associated with several mechanisms, including solar transient events and the dynamical evolution of the bow shock. After their formation, jets interact with the background magnetosheath population, exciting various waves and accelerating particles. When they reach the magnetosphere, they can penetrate the magnetopause, drive surface waves, and cause magnetopause reconnection. Their effects to the inner geospace environment can be seen through substorm activity and ground magnetometer measurements. In this thesis, a series of papers on the formation, evolution and statistical properties of jets is presented. Most of the work is done using NASA’s Magnetosphere Multiscale (MMS) mission, while other missions like THEMIS and upstream solar wind monitors (e.g., ACE and Wind) are also used. For our analysis, we also make complementary use of neural networks and computer simulations. Our investigation initially showed the importance of classifying jets based on the shock orientation and interplanetary magnetic field (IMF), resulting in an open-access database of magnetosheath jets using MMS. This dataset was then used to derive statistical properties for each class of magnetosheath jets (Paper I). The jets were also classified using neural networks (Paper II), while a comparison between their statistical properties and computer simulated jets was performed (Paper III). Another aspect we investigated through multi-point measurements is the excitation of waves due to the interaction of jets with the magnetosheath (Paper IV). We then focused on the formation and evolution of jets close to the Earth’s bow shock. We showed direct in-situ evidence that shock reformation and the evolution of upstream waves can generate downstream high-speed jets (Paper V). By evaluating the properties of jets on a kinetic level, we demonstrated that jets exhibit complex velocity distribution functions (VDFs) throughout their lifetime. Deriving partial plasma moments to isolate the jet from the background population, we revealed the limitations of studying these phenomena from a single-fluid perspective and how the derived partial plasma moments are related to the upstream solar wind and its foreshock structures (Paper VI).Plasmajetar i magnetoskiktet är transienta och lokaliserade förhöjningar av det dynamiska trycket nedströms om jordens bogchock. Flera olika generationsmekanismer har föreslagits, t ex transienta strukturer i solvinden eller dynamisk omformning av bogchocken. Efter att de har genererats vid bogchocken växelverkar de med bakgrundsplasmat i magnetoskiktet, där de exciterar plasmavågor och accelererar partiklar. När de når magnetopausen kan de korsa den, driva ytvågor, eller initiera magnetisk omkoppling. Plasmajetars effekt på rymdmiljön nära Jorden manifesterar sig genom substormar och markbaserade mätningar av jordens magnetfält. Denna avhandling innehåller att antal artiklar om genereringen, utvecklingen och de statistiska egenskaperna hos plasmajetar. Huvuddelen av arbetet är baserad på mätningar från NASAs MMS-satelliter, tillsammans med kompletterande data från andra satellitmissioner, som THEMIS och solavindsmonitorer (t ex ACE och Wind). För dataanalysen använder vi också neurala nätverk och plasmasimuleringar. Våra första resultat visade på vikten av att klassificera jetar baserat på relationen mellan bogchockens orientering och riktningen på det interplanetära magnetfältet. Denna klassificering resulterade i en offentligt tillgänglig databas, innehållande MMS-observationer av plasmajetar. Detta dataset användes för att bestämma jetarnas statistiska egenskaper för de olika klasserna (Artikel I), vilket följdes upp med en klassificering baserade på neurala nätverk (Artikel II), vilket jämfördes med plasmasimuleringar (Artikel III). En ytterligare egenskap hos plasmajetar, excitation av plasmavågor, undersöktes med flerpunktsmätningar (Artikel IV). Därefter fokuserade vi på genereringen och evolutionen av jetar nära jordens bogchock. Vi visar att direkta in situ-mätningar tyder på att dynamisk omformning av bogchocken och vågor uppströms om den kan generera plasmajetar i magnetoskiktet (Artikel V). Genom att studera jetars plasmakinetiska egenskaper visar vi också att deras distributionsfunktioner uppvisat ett komplext beteende under jetarnas livstid. Beräkningar av partiella plasmamoment för att isolera jetarna från bakgrundsplasmat visar på begränsningarna i att betrakta dessa fenomen som en enkel fluid, och hur momenten är relaterade till solvinden uppströms om bogchocken (Artikel VI).QC 20221031</p
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
