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
Microbial ecology and soil evolution
No full textPurpose: to try to understand how soil generates and works. Four experimental areas: dust on concrete square, 10 cm of raw construction sand on this same concrete, bare vegetable garden soil, cultured vegetable garden same soil.
Two radiation sensors were placed above these areas to measure the incoming (turned up) and departing (turned down) light - pyranometer (305-2800 nm) and pyrgeometer (4500-50000 nm) - from May to September. Temperature sensors were placed in the soil on the surface, at a depth of 5 and 10 cm (Figure 1). The soil was analyzed at the beginning (April) and at the end (August) of the experiment looking for: pH, totC, OC, totN, Ca, K, Mg and Na. With 3 samples per case, the following control trends were recorded: pH and CO decreased in bare soil, while they increased in the other three cases; total N increased in all cases except in vegetated soil; Ctot/Ntot increased il all cases except in bare soil; Ca increased and K decreased in all cases; Mg decreased in all except sand, while Na increased on cement and sand, and decreased in soil and vegetated soil.
Using the primers 16S for bacteria, 18S for Eukaryotes and ITS for fungi, the content in Operational Taxonomic Units of these categories of living organisms clearly distinguishes the dust of the concrete square from the other substrates, which in turn separate along a gradient that goes from sand to bare and cultivated soil. Some organisms definitely prefer dust on concrete (Cyanobacteria and Actinobacteria; Chloroplastida and Stramenipiles), others real garden soil (Chloroflexi and Acidobacteria; Eucaryota, Rhizaria and Amoebozoa; Glomeromycota).
The radiative balance is different in the 4 situations, with a shift in the balance towards redder emitted radiation when the complexity of the system increases. The study of these data is still ongoing, but we will have the definitive results to be presented to the Congress
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
