Belatedly hatching ornithology collections at the National Museum of Ireland
No full textFor the first time, summary details are presented for the ornithological collections of the National Museum of Ireland (Natural History) (NMINH). To date, new cataloguing efforts in collaboration with University College Dublin have documented close to 10,000 non-passerine bird skins and taxidermy mounts
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Prey deficit for reintroduced Golden Eagles (Aquila chrysaetos) in Ireland
No full textGolden Eagles (Aquila chrysaetos) were reintroduced to Ireland in 2001 following prey availability and habitat feasibility studies undertaken in the 1990s which deemed northwest Ireland as suitable for their ecological requirements. However, they have failed to reach the predicted population growth necessary to sustain a viable population in the long-term. It has been suggested that inadequate prey biomass may have led to the poor reproductive performance. To determine prey availability within the core range of reintroduced Golden Eagles in Ireland, pre-release density estimates for Irish Hare (Lepus timidus) and Red Grouse (Lagopus lagopus) - their main prey - were compared with post-release estimates derived from transect and camera trap surveys. Camera trapping suggested 0.2 hare detections/km2 in upland areas in Cloghernagore Bog and Glenveagh National Park Species Area of Conservation (SAC) indicating that the hare population is very low, corroborated by the local results in the National Hare Survey 2017-2019 which detected zero hares in the vicinity of Glenveagh. Tracks and signs on walked transects suggested 1.6 grouse males/km2 which was comparable to the 1.2 males/ km2 reported during 2006/2008. The availability of hares and grouse as sources of live prey was estimated at 1.5-2.4 kg prey/km2/year, which was 74-83 % lower than the 9.2 kg prey/km2/year estimated as required to maintain Golden Eagle productivity in Scotland. Thus, prey deficit may explain the poor performance of reintroduced Golden Eagles in Ireland. Land management or site interventions could potentially increase hare and grouse numbers to improve eagle productivity. As such, integrated landscape management interventions may be necessary to ensure the success of species reintroduction programmes

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
