Produzione e conservazione del documento digitale. Requisiti e standard per i formati elettronici
No full textIl volume pubblica i primi risultati di un progetto di ricerca scientifica sviluppato dal curatore dell’opera presso il Laboratorio di Informatica Documentale (LID) dell’Università degli Studi di Macerata, in prosecuzione dello studio sulla formazione e conservazione della memoria digitale di cui alla monografia dello stesso autore (anno 2005). Il volume si compone di due parti: la prima analizza il processo di conservazione digitale, dimostrando l’esigenza di una partecipazione attiva e qualificata degli archivisti nel re-engineering dei processi e nella regolamentazione della produzione documentaria, la seconda illustra le caratteristiche dei formati elettronici, individuando per essi un insieme di requisiti tecnologici in relazione alle esigenze specifiche della conservazione digitale a lungo termine
Archivi storici e risorse tecnologiche
No full textIl lavoro affronta le tematiche relative al rapporto tra archivi e risorse tecnologiche descrivendo le principali tipologie di risorse disponibili sia a livello nazioonale che internazionale. In particolare si concentra sui software di descrione archivistica, sui sistemi informativi archivistici e sulle risorse web per la ricerca archivistic
La produzione di documenti digitali compatibili con un processo di conservazione a lungo termine
No full textL’articolo è pubblicato nel volume, curato dallo stesso autore, che raccoglie i primi risultati di un progetto di ricerca scientifica finalizzato allo studio dei requisiti dei formati elettronici per la produzione di documenti informatici compatibili con un processo di conservazione digitale a lungo termine. L’autore rileva la necessità per le strutture di archivio di estendere la loro azione ai processi che attengono alla produzione documentaria allo scopo di evitare che siano archiviate entità elettroniche soggette a rapida obsolescenza o mancanti delle necessarie informazioni di contesto. In particolare, secondo l’autore, tutte le organizzazioni che si accingono a sostituire i tradizionali documenti cartacei con entità informatiche dovrebbere prevedere come prima fase la rilevazione e l’analisi dei processi di lavoro, e poi la loro riprogettazione con l’intento sia di cogliere le opportunità offerte dalle nuove tecnologie ICT, sia di approfondire gli aspetti della produzione documentaria che maggiormente incidono sulla formazione e conservazione degli archivi digitali
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
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
