Adult-Sapling Tree Data
No full text<p>The physical characteristics of 20 trees were measured on September 23, 2014 at 3:00-4:00pm in the Saywell Woodslot (York University, 43° 46' 9.228"N, 79° 30' 29.556''W). Adult Maple Trees were identified, along with the nearest sapling to the adult tree. For each adult tree, the diameter at breast height, and canopy coverage was recorded, along with the distance from the adult to the closest sapling of the same species. For each sapling, diameter at breast height was measured and recorded.</p
Impact of Plant Richness and Closeness to water on Insect Abundance
No full text<p> In order to study the relationship between plant species diversity, distance from a water source and insect abundance, a study was done at the Grassland, East of Osgoode Hall, beside the Pond (York University) on October 14 and October 21, 2014. October 14, 2014 was sunny and 18°C and October 21st was 5°C with rain. Distance from the pond was measured using three discrete areas; the first area from the start of the pond to 20m away, the second from 20m to 40m and the final area from 40m to 60m away from the pond. 1m x 1m quadrats were used to measure plant species richness, and sweepnets were used to sweep for insects in order to determine insect abundance. Transects were used to mark out regions across the perimeter of the pond. Each transect was placed 5m away from the first transect, along the perimeter of Strong Pond.</p
Biodiversity of Insects found in the Woodslot and Grassland
No full text<p>In order to study the abundance and diversity of insects in the grassland and woods habitats, a study was conducted in the Saywell Woodslot and Grassland, east of Strong College (York University), on September 30, 2014 at approximately 3:00pm. Insect abundance was observed using a quadrat. Each quadrat area was observed for 3 minutes, and data on the total number of insects (and snails), and the number of organisms from specific Classes was recorded. First quadrat was placed randomly in the habitat; each subsequent quadrat was placed 5 metres in front of the previous quadrat. 10 replications were done in the Woodslot and 10 in the Grassland.</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
