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

L'abitato della media età del Bronzo di Gorgo del Ciliegio (Sansepolcro, Arezzo). Dati preliminari sul contesto paleoambientale
No full textThe settlement of Gorgo del Ciliegio (Sansepolcro-Arezzo) is situated on an ancient terrace on the left bank of the Afra Creek, at about 400 metres above sea level, near-by the tuscan-emilian Appennines divide. During the six last years (2001 -2006) an area of approximately 178 square meters was investigated, resulting in the fi ndings of a living fl oor with several structures (pole holes, combustion structures, pits of different typology), including a small food oven of particular interest. The pottery retrieved from the deposit is represented by cylindrical, troncoconic and globular vessels, among which milk boilers are present, carinated shapes (bowls, cups) and some sherds decorated in the Appennine styles, which has allowed for the attribution of the site to an early phase of the Middle Bronze 3 (BM3). The Middle Bronze Age people settled on a preserved portion of an alluvial surface (T1a) standing about 10 meters higher than the coeval active channel of the Afra Creek, whose deposits are bounded by the surface T2. This location ensured a relative protection from fl oods being, at the same time, close to a large water source. Sedimentological features of the alluvial gravels bounded on top by T1a and T2 surfaces,
suggest a significantly different fl uvial style during the late Holocene compared to the modern Afra Creek. Before (e.g. T1a deposits) and during (e.g. T2 deposits) the human occupation at this site, the Afra Creek was characterized by a relatively wide (about 150 meters) valley with multiple shallow channels inside, fi lled by gravels. This style can be observed in some modern creeks of the Upper Tiber River basin, indicating local condition of channel overfilling. On the whole this ancient style contrasts with the modern one in which a few tens meter wide Afra Creek is deeply entrenched in the bedrock and still affected by erosive processes. Despite the different valley morphology attained during the late Holocene, the terracing of the Afra Creek recorded at the site, attests to successive readjustment of the river profile to repeated perturbation of base level possibly due to the active tectonic setting of the Upper Tiber River valley. The preliminary results of the archeozoological study demonstrate that the inhabitants of Gorgo del Ciliegio were involved in the rearing of mostly sheep-goats and pigs and cattle in the second place, and in the hunting of deer and roe-deer; domestic dogs were present on the site. Such a pattern and the geographic location of the site, might suggest that Gorgo del Ciliegio community mostly practised mobile pastoralism and the dogs may have been kept to assist with herding the animals. Preliminary pollen analysis of the archaeological soil, reveals a scarcity and a bad preservation of the pollen grains possibly due to a highly acidic environment. Nevertheless, few grains of Urticaceae point to local anthropic impact on the vegetation cover, fully consistent with the settlement activity
