A Study of the Effects of Immersion on Short-term Spatial Memory
Full text linkJohnson, Eric Arthur. M.S., Purdue University, August, 2010. A Study of the Effects of Immersion on Short-term Spatial Memory. Major Professor: Nicoletta Adamo-Villani. The goal of the study was to determine whether the level of immersion of a virtual environment has a significant effect on the user’s short term spatial memory. Two previous virtual environment development projects are reviewed: the Muscatatuck Virtual Tour and the 21st Century World Future City (Adamo- Villani, et al. 2009, 2010)). These projects show the viability of producing a virtual environment and a partially immersive, low-cost virtual reality system ,i.e. a Fish- Tank system (The system was used for the purpose of the study). Previous research is analyzed to demonstrate the viability of using virtual reality as a testing tool for measuring the effects of immersion on cognitive processes. Results of the study show that there is a significant difference in spatial memory when the level of immersion changes
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
Scotney: an archaeological survey and map analysis
No full textThis edited volume sets out the work of a team of scholars from Northwestern University and the University of Southampton led by Matthew Johnson, in collaboration with the National Trust. Between 2010 and 2014, different members of the group carried out topographical, geophysical and building survey at four different late medieval sites and landscapes in south-eastern England, all owned and managed by the National Trust: Bodiam, Scotney, Knole and Ightham. Studies were also undertaken into documentary, map and other evidence. A particularly important element of the research was to synthesise and re-present the ‘grey literature’ at all four sites. This volume seeks to present this work and discuss its archaeological and historical importance. It places the four sites and their landscapes in their setting, as part of the wider landscape of south-east England. It discusses the importance of these places in understanding later medieval elite sites and landscapes in general, and in terms of their long-term biographies and contexts. Central to the volume are the linked ideas of lived experience and political ecology in presenting a new understanding of late medieval sites and landscapes
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
