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

The particulate methane monooxygenase from Methylococcus capsulatus (Bath)
Full text linkThe isolation procedure for the pMMO complex has been optimised to obtain a high
specific activity enzyme from Methylococcus capsulatus (Bath). The enzyme is
comprised of the pMMO hydroxylase (pMMOH) consisting of polypeptides 47,26 and
23kDa molecular mass. In addition to this, a putative pMMO reductase (pMMOR) was
also found to be necessary to maintain propylene oxidising activity. This component
was found to consist of two polypeptides of approximately 63 and 8kDa. Preliminary Nterminal
sequence data of the large subunit ofpMMOR indicates that the sequence bears
70% similarity to the methanol dehydrogenase (MDH) from Methylococcus capsulatus
(Bath). Therefore, we tentatively propose that the" MDH can act as a reductase
component to the pMMOH.
The significance of this result prompted investigations into the previous published
proposals that electrons derived from the methanol oxidation reaction can be channelled
back into the methane oxidation reaction by the methanol dehydrogenase, independent
of NADH. Any effect of methanol to act as a reductant to pMMO in membrane
preparations was lost upon isolation of the pMMO complex, indicating the necessity to
maintain a fully functional methanol dehydrogenase (MDH) upon isolation. In addition
to this, the in vitro electron donors of pMMO, NADH and duroquinol were found to act
via distinct pathways of electron transfer (electron transport inhibitor studies).
Electron paramagnetic resonance (EPR) spectroscopy data provided evidence that the
copper in the active site of pMMO existed as a mononuclear copper (II) centre not a
trinuclear copper centre suggested by Chan and coworkers (Chan et al., 1993; Nguyen et
al., 1994, 1996a, 1996b, 1998). In addition to this preliminary data also indicates the
presence of an iron centre which is only EPR visible after reduction of the complex
suggesting the majority of iron in the complex is EPR invisible. The exact nature of this
iron centre is still unclear.
A structural study of the pMMO complex has also been undertaken using electron
microscopy studies in conjunction with single particle analysis. This allowed low
resolution projection maps of different views of the pMMO complex to be generated.
The complex appears to exist in a polymeric state of at least a dimer, possibly a tetramer
if the molecular weight analysis calculated by sedimentation equilibrium analysis is
taken into account.
This study has provided some insight into basic characteristics and the structure of a
duroquinol-driven pMMO complex and its interaction with other electron transfer
proteins
