Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Distributed Topology Inference for Power System Applications : Algorithms and architectures utilising industry standards
No full textThe electrical transmission and distribution system is undergoing unprecedented changes to meet the need for a carbon emission-free global energy system. An expected increase in the portion of end-user energy use in the form of electricity and need to integrate renewable energy sources into the power grid on a large scale require major changes in how power grids are operated and controlled.The systems and methods used to monitor, control and protect the power grid have developed in a context where the net power flow could be assumed to originate at large centralised power stations and be transmitted, distributed and delivered to end-users. The operation and control systems still largely follow a centralised and hierarchical structure with a control centre extending a multitude of connections out to automation systems over the geographical span of the grid. With the large-scale integration of distributed generation in the power system and the interconnection of grid infrastructures to facilitate inter-area trade of electricity, many of the premises on which traditional control systems were developed are currently changing. As more distributed generation capacity is integrated into parts of the power grid, efficient methods for determination of the electrical connectivity, the grid topology, become essential components for the development of all other control systems. The systems on which these methods are implemented must interoperate seamlessly with existing and future infrastructure. One effort to address this is an internationally coordinated standardisation process for power systems management and information exchange. The resulting standards, for example, IEC 61850 and IEC 61970, provide a framework for the development of new architectures and methods with a high level of interoperability whilst remaining applicable to the wide variety of equipment and applications that will be required. This thesis aims to test the hypothesis that distributing the application logic closer to the substation automation systems directly connected to the electrical process, provides a suitable architecture which can acquire system-wide knowledge of grid topologies without the assistance of a central entity. To achieve this, three research objectives are identified; proposing of novel control system architectures, utilising state-of-the-art structured data and equipment in substation automation systems and finally to develop a distributed topology inference algorithm utilising minimum prior knowledge of the grid it is acting within.The results firstly demonstrate the use of multi-agent systems as a distributed control and monitoring architecture. Secondly, the result demonstrates the application of relevant standardised IEC 61850 data models and interfaces for data exchange, and how they can be integrated into such architectures. Thirdly, the development of work on a multi-agent systems architecture and algorithm for distributed topology analysis of power grids is described and a formal description of the topology inference algorithm is given. Finally, a validation for the algorithm using a reference power grid model is presented.Det elektriska transmissions- och distributionssystemet genomgår oöverträffade förändringar för att möta behovet av ett globalt energisystem utan koldioxidutsläpp. En förväntad ökning av andelen energikrav för slutanvändare i form av el och behovet av att integrera förnybara energikällor i elnätet i stor skala kräver stora förändringar i hur elnätet drivs och styrs.De system och metoder som används för att övervaka, styra och skydda kraftnätutrustningen har utvecklats i ett sammanhang där nettoeffektflödet kan antas härröra från stora centraliserade kraftverk och överföras, distribueras och levereras till slutanvändare. Operations- och styrsystemen följer fortfarande i stor utsträckning en centraliserad och hierarkisk struktur med endriftcentral som navpunkt med en mängd anslutningar ut till automationssystem över nätets geografiska utbredning. Med den omfattande integrationen av distribuerad elproduktion på olika punkter i elsystemet samt sammankopplingen av elnätinfrastrukturer för att underlätta elhandeln mellan områden, förändras m˙anga av de premisser som traditionella drift- och styrsystem utvecklats under.Eftersom mer distribuerad produktionskapacitet integreras i olika delar av elnätet, blir effektiva metoder för bestämning av den elektriska anslutningen, dvs. elnättopologin, nödvändiga komponenter för utvecklingen av alla andra styrsystem. De system på vilka dessa metoder genomförs m˙aste kunna samverka sömlöst med befintlig och framtida infrastruktur. Ett pågående arbete med att bemöta detta är en internationellt samordnad standardiseringsprocess för styrning av energisystem och informationsutbyte. De resulterande standarderna, till exempel IEC 61850 och IEC 61970 Common Infromation Model, utgör ett ramverk för utvecklingen av nya arkitekturer och metoder med hög driftskompatibilitet medan de fortfarande är tillämpbara på ett brett spektrum av utrustning och applikationer som framgent kommer att krävas.Denna avhandling syftar till att testa hypotesen att en arkitektur där applikationslogiken distribueras närmare ställverksautomationssystem som är direkt kopplade till elöverföringsprocessen, utgör en lämplig arkitektur som kan förvärva systembred kunskap om elnättopologier utan hjälp av en central enhet. För att uppn˙a detta har tre forskningsmål identifierats; föreslå nya styrsystemsarkitekturer, utnyttja state-of-the-art strukturerad data och utrustning i ställverksautomationssystem och slutligen utveckla en distribueradtopologiinferensalgoritm som behöver minsta möjliga förkunskaper om det nät som det verkar inom.Resultaten demonstrerar för det första användningen av multi-agent-system som en distribuerad kontroll- och övervakningsarkitektur. För det andra visar resultatet att tillämpliga standardiserade IEC 61850 datamodeller och gränssnitt används för datautbyte och hur de kan integreras i sådana arkitekturer. För det tredje beskrivs utvecklingen av arbetet med en multi-agent systemarkitektur och algoritm för distribuerad topologianalys av elnät och en formell beskrivning av topologiinferensalgoritmen ges. Slutligen presenteras en validering för algoritmen med hjälp av en referenskraftnätmodell
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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.
