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
Review of the development of the Peregrine Falcon(Falco peregrinus)population in Hungary between 1997 and 2018
No full textPeregrine Falcon (Falco peregrinus) populations recovered globally after a dramatic decline experienced between the 1950s and 1980s. The conservation challenge forced the raptor biologist community to co-operate internationally. As a part of the co-operation, four conferences were organised to identify the problem, coordinate conservation efforts including research and to monitor the recovery process of the species’ populations worldwide. The line of conferences started in Madison (WI, USA) in 1965 and was followed by two conferences in Sacramento (CA, USA) and Piotrowo/Poznań (Poland) in 1985 and in 2007, respectively. The latest conference was organised in 2017, in Budapest, where Peregrine experts discussed the latest research and monitoring results. The event provides a good occasion to review the development of the Peregrine population in Hungary. The species became extinct in Hungary as a breeding species in the mid-1960s due to the intensive use of pesticides (DDT) and it returned only in 1997, when the first successful breeding was recorded. In 2018, 72 active eyries were recorded. The Hungarian population is the edge of the Carpathian Peregrine population and the birds represent mostly the nominate subspecies (F. p. peregrinus), but individuals showing typical phenotype of the Mediterranean subspecies (F. p. brookei) were also observed. The northern race of F. p. calidus also occurs on migration and in winter. The Hungarian population is sedentary. Natal dispersal of females is biased to males, but in case of both sexes most ring recoveries of adult birds occurred within the Pannonian basin. The increasing Peregrine population expanding to the lowland may cause conservation conflict on medium term by competing with the endangered Saker Falcon (Falco cherrug) for the nest sites. The conservation status of the Peregrine Falcon in Hungary is good in general, but threats may emerge on local scale in some regions. No specific conservation measures are taken, research and monitoring focus on population changes and threats posed on and caused by Peregrines
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
Observations of birds of prey in Eastern Nimba Nature Reserve, Liberia between 2015 and 2017
No full textDistribution and biology of birds of prey species have been well-documented in most parts of the
globe. Knowledge gaps are continuously shrinking due to more research, new technologies and increasing
possibilities to reach remote areas. However, there are still some regions where data on birds of prey are
scarce due to various reasons. Some parts of West Africa are such places, mostly because civil wars and the
outbreak of Ebola prevented any kind of research. In the period 2015–2017, a butterfly research project in
Nimba Mountains, Liberia offered opportunity to collect data also on birds of prey species. This article aims
to provide a comprehensive list of birds of prey species in the area and compare it to other available historic
and recent lists. In the frame of the project, 20 species were recorded. The results of comparing historic
and recent records show that species of dry open habitats appeared and even settled in Nimba Mountains’
predominantly rainforest habitat. That suggests a habitat shift likely due to both climate change and human
land transformation activities
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
