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
Intelligent terrain avoidance agent for General Aviation Free Flight
Get PDFDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references (leaf 24).In order to reduce the workload of Air Traffic Controllers, a new concept called Free Flight has emerged for General Aviation. This system takes the load off of the air traffic controller and puts the responsibility on the pilot. In order to help the pilot handle this responsibility, a hierarchical agent system is under development. This system will take information from traffic, weather, and terrain to determine a safe and efficient flight path. The terrain agent in this system must avoid Controlled Flight into Terrain. A simplistic conditional logic model was created and tested on a two-dimensional terrain slice. Then this algorithm was implemented with the dynamics of a Commander 700, a twin-engine general aviation aircraft. This algorithm was found to satisfy minimum altitude requirements and safely navigate the aircraft over the terrain conflicts for a simple terrain model. Further work, however, should be explored on adapting the algorithm for three-dimensions, testing on actual terrain, and implementing the terrain agent with the weather, traffic, and executive agents in this system
Breath of Life: A Biblical Understanding of the Human–Animal Distinction and a Critique of Contemporary Theological Anthropology
Get PDF“If you have no doctrine of creation, you have no doctrine of salvation.” With one pithy sentence, Peter Gentry exposes the foundational support for my dissertation. It has become popular recently in the interaction between theology and science to diminish the distinction between humans and animals. This is problematic. Starting from a basis of sola Scriptura, I look through the biblical data on humans and animals. The first chapters of Genesis are very important and are reviewed in detail. The following two chapters look at the rest of the Old Testament and the New Testament. From this data, it is clear that though humans are similar to animals, they are also distinct. Central to this distinction is the “breath of life” in man. This is an ontological distinction that includes both the physical capacities and immaterial aspect of man that are not found in animals. This includes man being made in the image of God, man’s moral stance before God, and the connection to Christ’s work as a man. Four modern theologians are reviewed who take a different methodological path with the result that they come to different theological conclusions. A final chapter brings together the biblical data with its implications for theology
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
