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
Forward simulation of groundwater level changes induced by deep drainage wells in Succiso earth slide (northern Apennines, Italy)
No full textThe Succiso landslide is a large scale active earth slide located in the northern Apennines of Italy, in the upper Enza river basin (Province of Reggio Emilia, Emilia Romagna
Region). It extends from 1075 to 800 m a.s.l., affecting an area of about 0.5 km2 for a length of about 1.6 km and a maximum width of 500 m. The landslide area is characterized by flysch and claystone bedrock, by glacial and landslide deposits of various type and by more than 2000 mm rainfall per year. The landslide is named after the village of Succiso, that was damaged by acceleration of earth slide movements in 1951, 1952 and, quite severely, in 1966 and 1972. Succiso was first declared, according to law 445/1908, as “to be consolidated” (DPR n 201 of 14/02/1957) and, later on, as “to be transferred” (DL n°976 of 18/12/1966 – G.U. 24/4/70). From 1972 to 2008 the landslide did not underwent any other particular acceleration event and presumably, it moved at rates in the order of few cm/year, as it does presently. Consequently, the village of Succiso was again re-classified as “to be consolidated” (DGR n° 686 of 12/05/2008). Following such recent administrative act, and in order to define, design and construct consolidation works, the local technical basin service (Emilia Romagna Region) has undertaken an intensive geological, geotechnical investigation and monitoring survey
that allowed to define the geological model and the on-going kinematics of the landslide's deposit. This work supports feasibility analysis of a shield of deep drainage wells to be possibly located in the central portion of the landslide (indicatively: 26 wells, diameter 1 m, depth 30 m, inter-axes 7-8 m, total length of shield 200 m, gravity discharge).Specifically, it performs a forward simulation of groundwater level changes induced by this possible deep drainage solution, using an hydrogeological modeling of the landslide based on 3D FEFLOW software, which has been calibrated thank to a continuous piezometric monitoring. A parent paper presented at this conference has complemented the feasibility analysis by using the outputs of this hydrogeological simulation as input to a geotechnical softsoil-creep model, in order to analysing the potential benefits, in terms of decrease in displacement rates, induced by deep drainage wells
A Native Extensible XML Query Processor Towards Efficient and Effective MPEG-7 Querying
No full textIn recent years the production of massive amounts of visual information has led to the arrival of very large multimedia Digital Libraries (DLs). The key to support efficient search and management operations in such repositories is to exploit metadata information for digital media, such as MPEG-7 based ones, which seem to be the most widely accepted. The underlying XML syntax, together with the high versatility of the provided constructs, make it easy to specify significant and complex queries, however executing them efficiently on huge quantities of data is not a trivial task. In this paper we provide an overview of the XSiter system, a native and extensible XML query processor providing very high performance in general XML querying settings and whose flexible architecture can be easily enhanced to better support the peculiarities of retrieving multimedia objects through MPEG-7 annotation metadata. Further, we consider possible "use-cases" and tasks related to multimedia and video DLs querying and management which our system can successfully accomplish
