Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
New ARMS Online Data Tool Allows Users To More Easily Access, Analyze, and Compare Farm Statistics
USDA’s Agricultural Resource Management Survey (ARMS) is the primary source of information on the production practices, resource use, and economic well-being of America’s farms and ranches. ERS recently released a new ARMS data dissemination tool that allows for more user interaction, includes charting capability, and has an application program interface (API) for direct queries
Predicting the aggregate economic impact of rural tourism events
Rural tourism is a rapidly expanding industry in Europe and America, experiencing an annual growth rate of six percent in recent past. The steady increase in rural tourism can help minimize the large gap between average rural income and average urban income. An issue Texas Department of Agriculture (TDA) faces in funding rural community events is whether these events will generate sufficient aggregate economic impact (AEI) to justify this public investment. The GO TEXAN Rural Community Program is a comprehensive program initiated by the TDA to enhance the growth and prosperity of rural Texas towns, cities and counties.
Using panel data this study develops a predictive model that explains variables that affect aggregate economic impact of rural events, where visitors spend their money based on the events' attractiveness. AEI is an important measure of the effectiveness of TDA funding of rural communities. It is calculated based on event and community characteristics and it is the total expenditures for a particular event multiplied by economic multiplier. We evaluated the total returns from 39 community events and seek to determine to what extent outcomes could have been predicted based upon available information. Event surveys from three consecutive years 2008, 2009 and 2010 are used as primary data.
The results reveal that the Ordinary Least Square (OLS) is a good fit for the model. Parameters coefficients of the explanatory variables such as event days, number of years, community investment, weather, folk/music, nature tourism, estimated miles, distance from major city, visitor rating, community population and median family income were statistically significant
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
