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
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
Il lavoro degli italiani all'estero e degli stranieri in Italia

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
L’acciaio: materia e tecnica del progetto di recupero
No full textLa vicenda tecnica dell’uso dell’acciaio nel campo del recupero ben esplicita il cambiamento che la diversa considerazione del dato materiale induce negli esiti di progetto. L’acciaio ha mutato nel tempo il suo ruolo passando da quello esclusivamente tecnico legato agli aspetti del consolidamento a quello di vero e proprio elemento di progetto capace di sostanziare la conservazione dialogando da posizione “moderne” con la preesistenza.
Nella tradizione tutta italiana del progetto di recupero, che inizia con Carlo Scarpa e Ignazio Gardella, proseguendo con Guido Canali e Massimo Carmassi, , ecc., l’acciaio diviene il materiale per eccellenza con cui tentare una sperimentazione formale e tecnica spinta verso una progettazione di dettaglio che rivendica la sua dimensione artigianale molto vicina ai modi della costruzione degli edifici antichi. Ricercare proprietà e significato della materia ed in particolare le diversità linguistico-sintattiche connesse alla sua natura, significa assumere il materiale come elemento centrale di un processo primariamente formativo e creativo, sostanziato attraverso un successivo atto tecnico.
La sperimentazione del dato materiale e tecnico dell’acciaio nello specifico progettuale del recupero è divenuta una modalità operativa con cui costruire, in relazione a intenzionalità diverse, una relazione possibile tra testo originario e testo critico, declinando il binomio Analogia/Contrasto con differenti tonalità sia tecniche che figurative. La conservazione può essere operata analizzando la materia preesistente sia nelle sue intenzionalità dichiarate, che hanno strutturato la logica propria dell’edificio, che in quelle potenziali e latenti, valutabili in relazione alla diversa disponibilità alla trasformazione dell’oggetto costruito; queste ultime divengono un ambito di sperimentazione, sia tecnica che formale, o giocata all’interno della logica propria dell’edificio (analogia) o, attraverso l’integrazione con materiali nuovi, spinta verso configurazioni rispondenti a codici formali e tecnici diversi (contrasto).
In quest’ottica l’acciaio diviene un supporto materico duttile, specializzato e compatibile cui rinviare la soluzione di alcuni aspetti della conservazione rispetto sia a nuovi assetti spaziali e funzionali che più strettamente tecnici e costruttivi.
L’uso dell’acciaio si traduce da una parte, nella configurazione, univoca o ibrida, di componenti funzionali e costruttivi, vecchi e nuovi, unici o seriali, che definiscono nuovi rapporti formali e costruttivi con la preesistenza e, dall’altra, nell’opzione tecnica della sospensione, diretta e indiretta, specializzata al sistema dei connettivi verticali e orizzontali che, attraverso un rovesciamento del criterio fondativo, media la riduzione e risoluzione delle interferenze con la stessa preesistenza.
A partire da alcuni interventi esemplari che ben identificano questo approccio progettuale e tecnico sull’esistente, il contributo prende in considerazione alcuni progetti di recupero realizzati nel Lazio meridionale significativi per la natura tipologica del manufatto originario e per le diverse articolazioni tecnico-costruttive e linguistico-formali degli interventi caratterizzati dall’uso dell’acciaio.During the time the steel changed its rule, going from technical ones connected to reinforced aspects, to one of project element capable to legitimize the conservation dialoguing from modern position with the pre-existence.
In the preservation project the definition of possible relation between primary and critical text can be research trough an experimentation of steel material data capable to solve the Analogy/Contrast binomial words achieving technical and figurative different tonalities.
In this point of view are analysed same refurbishment project, realised in southern Lazio, significant for the different typology of original buildings and for the modality of steel use; it becomes material support specialised, compatible and adaptable for solution of same conservation problems, in particular the functional and spatial new dimensions and technical and construction new aspects.
In this projects the steel is used in the configuration of functional and construction components, old or new, single or serial, defining the new formal and construction relations with the pre-existence; but also in the technical option of suspension, direct and indirect, specialised to all system of stairs and platforms, modulating the reduction and resolution of pre-existence interference through a different criteria of construction foundation
