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
Parziali assenze. Sigle e marchi su strumenti della produzione ceramica (VI-III sec. a.C)
No full textSe la presenza di marchi e sigle apposti sul prodotto finito parrebbe cosa piuttosto nota e frequente, simili attestazioni risultano invece alquanto rare su alcuni tipi di strumenti utilizzati durante determinate fasi della chaîne opératoire che caratterizza i processi di produzione della ceramica (distanziatori, barre da fornace etc.). Lo scopo di questo studio sarà quindi quello di presentare le attestazioni note cercando di comprendere il motivo di questa quasi totale assenza di marchi di fabbrica o sigle di produzione nell’ambito di officine che già dal periodo arcaico possono considerarsi specializzate, con un’articolata divisione del lavoro e con volumi di produzione tali da far pensare al coinvolgimento di un numero nutrito di professionisti capaci di gestire impianti di cottura spesso condivisi da più maestranze. Verrà quindi introdotto come caso studio quello del quartiere artigianale di Veio-Piano di Comunità – adibito alla produzione di bucchero - che ha restituito strumenti marchiati e tuttora senza confronti puntuali nel panorama dell’Italia preromana
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
Fornaci e strumenti per la produzione di ceramica a Veio-Piano di Comunità
No full textIl quartiere artigianale attivo tra la fine del VII e per tutto il VI sec. a.C, legato alla produzione di bucchero messo in luce nel distretto meridionale del pianoro di Veio in loc. Piano di Comunità, ha restituito una quantità notevole di manufatti appartenenti ad alcune parti strutturali delle fornaci rinvenute in situ, insieme ad un gruppo di strumenti impiegati durante le diverse fasi di lavorazione e produzione della ceramica. La vocazione artigianale dell’area, a cui riportano tali rinvenimenti, è probabilmente da ricondursi alla presenza della vicina area sacra indiziata dal ritrovamento di importanti e disparate testimonianze . In questo contributo verranno presentate alcune novità derivanti dallo studio di queste due categorie di testimonianze privilegiandone l’aspetto tecnologico e tipologico e aggiornando alcune considerazioni avanzate in precedenza; l’intento è quello di sottolineare l’importanza di tali rinvenimenti nell’ambito generale delle nostre conoscenze (non approfondite e poco sistematiche) degli impianti di cottura della ceramica di epoca arcaica e più in particolare della tecnologia di produzione del bucchero.
Il materiale rinvenuto può essere enucleato in cinque diversi gruppi, afferenti a due categorie di utilizzo: un impiego all’interno delle fornaci, come parte integrante della loro struttura ed organizzazione interna, e uno in associazione al vasellame. Al primo caso fanno riferimento le cosiddette “barre da fornace” (firebars) e i cosiddetti “canaletti”; nella seconda categoria rientrano invece i distanziatori e i sostegni. L’ultimo gruppo, quello delle cosiddette “calotte”, può rientrare in entrambe le categorie in base alle diverse ipotesi di utilizzo
The Architecture of Firing: The Interplay between Tradition and Innovation in the Potter’s Workplace
No full textCrafting spaces are places where traditional and experimental approaches are combined to meet the
needs of production. Thanks to the archaeological record, we can indeed observe these opposite
aspects through specific evidence: the products and the structures used for firing. Arguably, changes
recorded in the way pottery objects were fired, may originate both and at once from the adoption of
a traditional way to transmit knowledge (e.g., empirical learning or by observing craftsmen roles
within the workshop) and innovative ways to use it (either discovered by accident or as a result of
an external contribution). Hence, this paper aims at assessing the impact that particular changes in
the architecture of pre-Roman kilns – as recorded specifically but not exclusively among the
Etruscan ones, from the end of the 9th to the beginning of the 5th century BC – may have had in the
development of the firing processes, indeed expressing a unique interplay between tradition and
innovation that can be found only in the potter’s workplace. By considering specific case-studies
and using an interdisciplinary approach, which will combine experimental archaeology,
ethnographic research and 3D modelling I will try to evaluate the impact of social and technological
factors, such as the introduction of a foreign know-how in the organization of the chaîne opératoire.
On the other hand, I will finally discuss how the preservation of a rigorous modus operandi may
contribute to the product’s standardisation
