A Snicker of Magic
No full textThere was a time when Midnight Gulch was known for its magic. That, however, was long before Felicity, her little sister, and her wandering mother move to town. Now all the magic left in the town is a small snicker, and of course the Beetle—a person who goes around town performing anonymous good deeds. Felicity loves what she finds in Midnight Gulch. She loves her aunt and uncle as well as her best friend Jonah. This is her first real home and she is determined to stay. She works hard and manages to break the curse on the town and her mother so that they can all live there happily

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Towards realistic orbit-following simulations of fast ions in ITER
No full textOne of the main scientific goals of the international ITER experiment is to provide understanding of burning plasmas, including the behavior of fusion-born alpha particles. These particles form both a potential risk for the first wall and a massive source of free energy in the plasma. Such free energy can drive a multitude of MHD modes, most notably the Alfvénic ones, that can lead to increased transport and even losses of fast ions.
In this work, the alpha particle physics has been studied using kinetic orbit-following Monte Carlo code ASCOT. The code was enhanced with two new physics models. The first model relaxes the usual guiding center (GC) approximation used to save computation time. In some cases, this approximation is not valid and the full gyro motion (FO) has to be resolved. The second model is for fast ion relevant MHD modes and its implementation allows taking into account electromagnetic fields due to these modes.
When the MHD model was used to simulate ITER plasmas, the wall power loads due to fast particles were not found to exceed the design limits of the wall materials even for unrealistically large perturbations. However, redistribution of fast ions was observed to alter the alpha particle heating profile and neutral beam ion (NBI) driven current profile.
Fusion alphas were simulated for the ITER 15 MA scenario using different integration methods. Following the full gyro motion gave slightly larger alpha particle wall power loads than the GC method. Since the FO method uses more than 50 times more CPU than GC integration, a third method was introduced as a compromise between the speed and accuracy: the GC method is used in the plasma core and FO integration is activated in the vicinity of the wall.
Finally, alpha-driven current and torque in ITER were studied using different magnetic field configurations. It was found that, independent of the magnetic configurations, the alpha-driven current is less than 1% of the total plasma current for both 9 MA and 15 MA baseline scenarios. On the contrary, the alpha-driven torque depends on the magnetic field configuration. While in the axisymmetric case the total torque was found to be close to zero, with realistic 3D effects the alpha particles produced substantial torque, about one tenth of that driven by the NBI particles, but in direction opposite to it.Maailman ensimmäisessä fuusioreaktorissa, ITERissä, on tarkoitus oppia ymmärtämään palavien plasmojen fysiikkaa ja siten valmistella tietä kaupalliselle fuusioenergialle. Fuusioreaktioissa syntyvät nopeat alfahiukkaset sekä neutraalisuihkukuumennuksesta (NBI) syntyneet nopeat ionit aiheuttavat riskin ensiseinämän kestävyydelle. Hiukkasten sisältämä vapaa energia mahdollistaa monenlaiset magnetohydrodynaamiset (MHD) epästabilisuudet. Nämä MHD-häiriöt voivat aiheuttaa nopeiden hiukkasten kulkeutumista jopa ulos plasmasta.
Tässä työssä on tutkittu alfa- ja NBI-hiukkasten fysiikkaa käyttäen apuna kineettistä Monte-Carlo menetelmään perustuvaa radanseurantaohjelmistoa nimeltään ASCOT. Koodia on täydennetty numeerisilla malleilla, joista ensimmäinen mahdollistaa johtokeskusmenetelmän (GC) testaamisen ja tarvittaessa korvaa sen. Menetelmässä ratkaistaan hiukkasen gyroliike magneettikentän ympäri (FO). Toinen malli ottaa huomioon tiettyihin MHD ilmiöihin liittyvien sähkömagneettisten häiriöiden vaikutuksen nopeisiin hiukkasiin.
Ensimmäistä mallia sovellettiin ITER:n perusplasmalle (15 MA) ja havaittiin, että FO menetelmällä laskettu alfahiukkasten aiheuttama seinäkuorma on suurempi kuin käytettäessä GC menetelmää. Koska FO menetelmä vaati noin 50 kertaa enemmän laskenta-aikaa, esiteltiin uusi hybridimenetelmä, joka siirtyy käyttämään FO radanseurantaa vain seinämien lähistöllä.
MHD-mallia käytettiin useissa erilaisissa ITER-simuloinneissa. MHD-häiriöt eivät aiheuttaneet missään tapauksessa merkittävää lisäystä nopeiden hiukkasten tuottamiin seinäkuormiin. Sen sijaan MHD-häiriöt vaikuttavat nopeiden hiukkasten jakaumaan plasman sisällä. Tämä uudelleen jakautuminen aiheutti muutoksia sekä alfahiukkasten kuumennusprofiilissa että NBI-hiukkasten ajamassa virtaprofiilissa.
Työssä laskettiin myös alfahiukkasten aiheuttama sähkövirta ja vääntömomentti erilaisten magneettikentän häiriöiden läsnäollessa. Alfahiukkasten synnyttämä virta oli kaikissa tapauksissa alle 1% kokonaisplasmavirrasta. Alfahiukkasten ajaman väännön puolestaan havaittiin riippuvan ulkoisista häiriöistä: aksiaalisesti symmetrisessä tapauksessa väännön komponentit summautuivat nollaan, mutta 3D häiriöiden läsnäollessa alfavääntö oli nollasta poikkeava. Alfaväännön suuruus on kuitenkin kertaluokkaa pienempi kuin NBI-hiukkasten aiheuttama vääntö ja lisäksi vastakkaissuuntainen
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
The Thursday Murder Club: Launching a megabrand author - a publishing case study
No full textIn 2020, the Christmas book charts in the UK made headlines: Barack Obama’s eagerly awaited autobiography, The Promised Land, was beaten to the top spot by The Thursday Murder Club by Richard Osman, a debut cosy crime novel set in a retirement village. Not only did Osman’s book beat the former US president’s expected bestseller, it also broke records, becoming the fastest-selling debut crime novel of all time. Although Osman has a certain level of fame in the UK from his TV appearances on shows such as Pointless, his celebrity status does not entirely explain the novel’s huge sales. This article tracks the acquisition, publication, and promotion journey of The Thursday Murder Club in order to understand the industry and cultural context of its success and to interrogate the role of celebrity in the creation of author brands. The findings suggest that the unexpected scale of the success of the book owed to a number of factors, including in-depth editing by the novel’s agent, editor, and author to tighten up the plot, an extensive and strategic promotional campaign, the pandemic (which drove interest in the book’s genre and themes), and the quality of the writing. We find that the book’s success was accentuated by Osman’s celebrity status rather than being entirely reliant on it. This research adds to the growing scholarship on celebrity authorship by means of an in-depth case study and provides insight into the processes behind publishing a ‘celebrity’ book and launching a megabrand author
Interaction of high-energy neutral beams with Divertor Tokamak Test plasma
No full textThe Divertor Tokamak Test (DTT) is a new, super-conducting device, being constructed in Frascati, Italy. DTT will be capable of plasma operations at high density and high heating power, in conditions relevant to address the power exhaust issue in support of ITER operation and DEMO design. DTT foresees the installation of a mix of auxiliary heating systems to couple up to 45 MW to the plasma, including Neutral Beam Injection (NBI). The neutral beam injector is currently being designed, aiming at delivering tangentially to the plasma neutral particles at energy of 510 keV, with a total power of -10 MW. In the present work, we apply for the first time the orbit-following Monte Carlo code ASCOT to DTT, in order to analyse with more details the interaction of the high-energy beam, described in real geometry beamlet by beamlet, and the plasma. The results of the simulation give an insight of the behaviour of beam energetic particles in DTT. Thanks to the flexibility of DTT, different plasmas can be generated, e.g. in terms of plasma shape due to different divertor concepts. We present the comparison of two cases with different plasma vertical positions and we analyse the effect on beam absorption in the plasma. We then present a sensitivity scan on plasma density, to verify the coupling of beam power at densities lower than the reference target scenario. These investigations are crucial to provide feedback and suggestions to DTT design and to assess the beam fast ion physics for plasma scenario developments.SP
