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
Diagnosis of viral skin diseases of ruminans in Romania
No full textDifferents viral species cause skin lesions in domestic ruminants, among all notifiable FMDV,
BTV and poxviruses but also parapoxviruses (PPVs), Herpesvirus and Papillomavirus. The
clinical aspect of skin disorders lead to frequent cases of misdiagnosis with possible severe
consequences in terms of economic impact and zoonotic transmition. The possibility to
identify the viral agents responsable of skin lesions with rapid direct method could help the
definitive diagnosis. In the last years, in Romania the most common skin diseases affecting
the domestic ruminanants are mainly those caused by PPVs ., Orf virus (OV), the prototype of
PPV genus, affected the adult goats and the kids, with lesions localised in the mouth area,
legs and on in the hudder. Cattle are frequently found to be affected with viruses causing
multiple skin lesions spread all over the body traditionally defined as papilomatosis. To
identify the etiological agents causing cutaneos diseases in domestic ruminants from
Romania, skin and scab samples have been collected from affected cattle and goats
respectively. The animals were farmed in two different locations Iasi and Botosani. PCR has
been performed on DNA extracted from either skin or scabs, in particular for the identification
of PPVs a fragment of the conserved gene B2L has been amplified using primers PPPI and
IV while for the detection of bovine papillomavirus we used FAP59 and FAP64 primers
targeted to the conserved L1 gene of Human papillomavirus (HPV) but able to amplify a
broad spectrum of papillomavirus species. Our results showed that the skin lesions found in
goats were caused by PPV and subsequent sequencing demonstrated orf virus as the
causative agent. The PCR performed on bovine lesions confirmed the presence of Bovine
papillomavirus DNA. This study demonstrated that PCR can be effective for a rapid
identification of viral agents responsible of skin diseases of ruminants. This technique is also
useful as a starting point for genomic characterization of virus strains circulating in Romani
The sustainable lightness of environment sociology applied to hotels retrofit
No full textThe sociological approach to the issue of environmental renovation (or
green retrofit) of hotels within the S.O.L.E.H. project interacts with other disciplines, providing operators in the construction chain with tools for evaluating costs, materials and retrofit practices. Specifically, it aims to offer information at three levels of analysis, according to an already tested scheme for energy and water issues [Osti, 2019; 2020]. A rigid hierarchical vision of disciplines is abandoned, in favour of a more flexible and interdisciplinary one. The paper is composed of two parts. In the first (longer one), the analysis scheme will be briefly illustrated and it will be exemplified with the specific case of retrofit, seeking analytical and practical connections with the S.O.L.E.H. research. In the second (shorter one), some considerations will be drawn on the usefulness of an integrated approach to the study of socio-environmental phenomena
