Ecology of the sand lizard (Lacerta agilis L.) in Southern England and comparisons with the common lizard (Lacerta vivipara jacquin)
No full textThe ecology of the sand lizard (Lacorta agilis) and the sympatric common lizard (Lacorta vivipara) was studied at two sites in Dorset, England from 1975 to 1977. Lizards wore caught in dry pitfall traps at one site and by hand at the other. Each individual caught was weighed, measured, and marked, before release. Diet was studied by faecal analysis. Both species took invertebrate pray of a variety of types and sizes but there were several taxonomic differences in prey taken. L. gilis took larger and border prcy than L. vivipara. Relationships between prey length and snout-vent length were examined for both species„Prey of L. agilis in spring was smaller, harder, and less diverse than in summer. Food consumption, measured by production of nitrogenous excreta, was lower in spring. Factors affecting production of nitrogenous and faecal excreta were investigated. Faecal excreta was unsuitable as a measure of food consumption for L. agilis because of its relationship with prey hardness.Stomach capacity of L. agilis was much greater than normal daily levels of food consumption. Individuals appeared capable of exploiting locally and seasonally abundant prey by feeding at high rates.Reproductive effort of L. agilis increased with age. Annual adult mortality was estimated as 28%. Densities at both sites wore approximately 50 individuals hectare 1. Sub-adult L. amilis grow faster than sub-adult L. vivipara 3~horgy devoted to growth by different ago classes of both species is compared. Individuals of L. agilis had overlapping home ranges and did not defend territories. It is suggested that home range size is too large to allow resources to be defended. Pitfall traps caught 7 times more L. agilis than L. ivipara. Rates of capture of L. agilis increased with increasing temperature and radiation whereas those of L.vivipara did not.</p

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
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
