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
Valutazione disponibilità biomasse agro-industriali a livello nazionale e loro pubblicazione sul portale Webgis atlante delle biomasse
Full text linkQuesto rapporto ha come obiettivo quello di valutare la disponibilità potenziale di biomasse/sotto- prodotto, per il territorio nazionale e la loro pubblicazione sul portale WebGis ENEA “Atlante delle Biomasse”. La necessità di svolgere tale attività deriva dalle sfide che il legislatore si è posto. Infatti l’Unione Europea punta da una transizione entro il 2050 verso un’economia decarbonizzata in cui viene fortemente incentivata la bioeconomia, ovvero un’economia basata sull’utilizzo sostenibile di risorse naturali rinnovabili e la loro trasformazione in intermedi o prodotti finali cosiddetti “biobased “. Un ruolo fondamentale per affrontare tali sfide può essere svolto dall’uso delle biomasse come materia prima per produrre energia rinnovabile, prodotti chimici e biocarburanti. La dotazione di banche dati nazionali sulle biomasse è un requisito della nuova direttiva UE sulle energie rinnovabili. I database presentati nel presente report sono stati ottenuti attraverso una metodologia precedentemente vali- data in ENEA ed aggiornata di recente. Nel presente lavoro viene riportata la disponibilità nazionale per l’anno 2018 delle paglie di cereali, le potature di alberi da frutto, di ulivo, di vite, i gusci di frutta secca, il pastazzo degli agrumi, la sansa derivante dalla molitura delle olive da olio e la vinaccia derivante dalla filiera uva-vino. Tutti i dati elaborati, compresi i dati degli anni precedenti, sono stati pub- blicati sul portale WebGis “Atlante delle Biomasse”. Il portale è stato sviluppato al fine di fornire a tutti gli stakeholder uno strumento di supporto decisionale sulla disponibilità e distribuzione geografica delle biomasse. Dall’analisi svolta si evince che la biomassa maggiormente presente a scala nazio- nale è la paglia di cereali, con circa 14.330 chilo tonnellate di sostanza secca all’anno (ktss/anno) seguita dagli scarti di potature, con circa 2.264 ktss/anno. La terza biomassa prevalente è la vinaccia, con una potenziale disponibilità di circa 824 ktss/anno, segue la sansa con 424 ktss/anno, l’olio vegetale con 322 kt/anno, il pastazzo di agrumi con 302 ktss/anno e i gusci di frutta secca con 118 ktss/anno. I dati al 2018 confermano gli andamenti acquisiti nel periodo precedente. Parte del lavoro presentato nel presente report è stato svolto nell’ambito del progetto REBIOCHEM (finanziato dal Programma Operativo Nazionale "Ricerca e Competitività" 2007-2013-PONREC).This report aims to assess the potential availability of biomass/by-product, for the national territory and their publication on the WebGis ENEA portal "Atlante delle Biomasse". The need to carry out this activity derives from the challenges that the legislator has set itself. In fact, the European Union, by 2050, intends to be a prosperous, modern, competitive and decarbonised economy in which the bioeconomy is strongly encouraged. A key role in addressing these challenges can be played by the use of biomass as a raw material to produce renewable energy, chemicals and biofuels. The provision of national biomass databases is a requirement of the new EU directive on renewable energy. The da- tabases presented in this report have been obtained through a methodology previously validated in ENEA and recently updated. This work shows the national availability for the year 2018 of the cereal straws, the pruning of fruit trees, olive trees, grapevines, dried fruit shells, citrus pulp, pomace resulting from the milling of olives for oil and marc from the grape-wine chain. All the data processed, including data from previous years, have been published on the WebGis portal “Atlante delle Biomasse”. The portal was developed in order to provide all stakeholders a decision support tool on the availability and geographical distribution of biomass. The analysis carried out shows that the biomass most pre- sent on a national scale is cereal straw, with about 14330 kilo tons of dry matter per year (ktss/year) followed by pruning waste, with about 2264 ktss/year. The third prevalent biomass is marc, with a po- tential availability of about 824 ktss/year, followed by pomace with 424 ktss/year, vegetable oil with 322 kt/year, citrus pulp with 302 ktss/year and the shells of dried fruit with 118 ktss/year. The 2018 data confirm the trends acquired in the previous period. Part of the work presented in this report was carried out within the REBIOCHEM project (funded by the National Operational Program "Research and Competitiveness" 2007-2013-PONREC)
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
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.
