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
Leveraging Data Mining and Market Segmentation to Gain Conservation Opportunity Intelligence
No full textRural landowners are an important audience for conservation messages about natural resource management. On-going collaborations between scientists, academics, and practitioners are producing actionable intelligence related to reaching, engaging and influencing rural landowner messaging and program marketing. One goal of such collaborations is to improve conservation program enrollment. Recently, market research and market segmentation approaches have generated a better understanding of the drivers for natural resource management program participation. This pilot study demonstrates a proof of concept using analytic processes which can be effective for market segmentation. A cluster analysis, using a representative two county sample and an empirically based set of variables, was instrumental in identifying seven landowner types that explain interest or willingness to be program participants. Using these clusters, I generated maps of landowners who represent opportunity for engagement. Techniques for understanding the human dimensions of conservation in a priority resource area and the groups of landowners who may be receptive to program messages are explored and explained. Based on the success of this clustering method, other landowner engagement campaigns could consider following this approach to increase their predictive abilities and improve return on investment in direct response marketing campaigns.Geography and Environmental Studie
A Place for Bourbon? A Geographical Analysis of Bourbon Production in the United States
No full textBourbon is often referred to as the “American Spirit”and rightly so. In 1964 when congress passed Title twenty-seven of the code of Federal Regulations legally protecting bourbon as a distinctly American product, limiting its bounds of production to the United States. Despite this, there is a common misunderstanding that bourbon must be produced in Kentucky, which leads to a unique dichotomy between the true geography and the understood cultural geography of bourbon. At present, however, there has been little if any research on the spatial distribution and character of the bourbon industry’s expansion. This study utilizes a survey of bourbon distillers across America as well as a site suitability analysis to better understand the relationship between the current distribution of bourbon distillers and the historical narrative of bourbon. This study also utilizes the concept of terroir to assess if bourbon distilleries have situated themselves in settings reminiscent of the predominant bourbon producing regions in Kentucky, thus exploring the relationship between modern distillers, the bourbon they produce, and the historical and perceived geographies of bourbon.Geography and Environmental Studie
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
