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
Guns and Grades
Get PDFLaws protecting the right to carry a concealed handgun on college campuses have been passed in eleven states to date, March 25, 2017, and additional states are considering similar legislation. A primary intent of these laws is to allow a person to utilize his or her second amendment right to bear arms to self protect from mass shootings on college campuses. However, there may be an unintended consequence from these laws permitting guns on college campuses: has permitting college students with licensed concealed handguns on campuses created a sufficient amount of fear in the participating university administrations to create a positive shift in the average grade distributions? To phrase more simply, are professors more likely than not to provide better grades for fear of students��� carrying a permitted firearm? If this is the case, does the marginal benefit of protecting the second amendment outweigh the marginal cost of grade integrity
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
Cost, efficiency, and the optimal number of firms in spatial markets
No full textTypescript (photocopy).In markets where firms and buyers are separated by costly distance, the degree of competition is believed by some economists to be less than perfect. Under these circumstances, many economists have demonstrated through the use of theoretical models that the long run equilibrium outcome does not contain all of the desirable features that exist in perfectly competitive industries. Specifically, it is suggested that there are too many firms and each firm's rate of output is too low to achieve the minimum average cost of producing and transporting its product. Since resources are believed to be employed in less than the optimal manner, some theorists suggest that some form of government regulation can improve the performance of spatial markets and can achieve the "optimal" number of firms. A widely accepted theoretical model representing a spatial industry has evolved in the literature. Basically the same model is presented in this dissertation except that the abbreviated cost function used in spatial models is replaced with one that contains the more generally accepted U-shaped average cost characteristic. The model is then used to examine a variety of industry solutions under the condition that each firm is forced to charge a price that is equal to its average cost of production. Maintaining the zero profits condition, a planner may alter the number of firms in order to achieve a variety of results, each of which contains some desirable feature. The model is also used to examine three of the possible free market equilibria. Each of the market solutions is unique because of the different price reactions that are assumed to exist between the firms. After obtaining the market results and the planner's results the two are compared to determine the possible conditions that can exist in a spatial industry. After the comparison, some concluding remarks are offered
