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
Predicted response of the lichen epiphyte lecanora populicola to climate change scenarios in a clean-air region of northern Britain
No full textStudies in the response of vegetation to predicted future climate change have focussed on vascular plants and are therefore largely unrepresentative of wider botanical diversity (i.e. comprising cryptogams; algae, mosses, liverworts and fungi including lichens). This paper presents a study to predict the response of a cryptogam species, the epiphytic lichen Lecanora populicola, to climate change scenarios. L. populicola is an easily dispersed species that occurs predictably in a widespread habitat, i.e. aspen stands. The study area was geographically constrained to a clean-air region of northern Britain. Thus, using the popular bioclimatic envelope approach, the projected climatic response of L. populicola is not expected to be confounded by air-borne pollution effects, or dispersal and habitat limitation. Non-parametric multiplicative regression was used to describe the response of L. populicola to seven climate variables, and an optimum model projected using UKCIP02 scenarios, comprising two time-frames (2020 s and 2050 s) and two greenhouse gas emission levels (low and high). Model predictions suggest an overall increase in the potential range of L. populicola, and, by association, several other ‘Boreal’ lichen epiphytes. Projected increases in the occurrence of L. populicola are associated with predicted summer drying, and indicate a putative threat to negatively associated ‘oceanic’ lichens
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
Wind Energy Feasibility and Energy Education Project Lower Sioux Community
No full textThe results of wind speed and direction measurements carried out in the Lower
Sioux Community during the twelve~month period from November 1, 1995, to October
31, 1996, are reported. The measurement were performed using six wind anemometers
and six wind direction vanes installed at four sites in the community. The data presented
include the monthly averages of the semi~hour1y wind speeds and of their cubes, monthly
wind roses, the probability distributions of the wind speeds and the parameters of Wei bull
distributions fitted to them, turbulence intensity data, and total energy roses for each
month.
The data are presented so as to streamline a comparison with wind energy data at
other area sites where comparable records may be available. Possible sites and
methodology for such a comparison and errors which may arise in a potential
extrapolation of the twelve-month record to longer time periods are discussed.Office of the Environment Lower Sioux CommunityFarell, Cesar; Ellis, Christopher R.. (1997).

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
