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
Educational and informational delivery method preferences of Mississippi beef cattle producers
Get PDFDue to the production costs associated with beef cattle production, it is important to equip beef cattle producers with sound, research-driven information to aid in the decision making process regarding their operation. Extension personnel as well as other organizations involved with beef cattle producers should be knowledgeable of the audience that they are disseminating information to and how this audience prefers to receive information. Knowing the demographics and educational and informational needs of the audience helps shape programming endeavors to meet the needs of the audience. The beef cattle producers surveyed indicated that they preferred to receive information from farm and feed supply dealers, other cattle producers, farm demonstrations, and cattle and farm magazines. The average producer was 53.6 years of age, had been involved in beef cattle production for 28.4 years, was a college graduate, and received less than 25% of their total income from their beef cattle operation
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
A multi-method study of the influence of online and traditional media on public opinion of antibiotic use in livestock
Get PDFFor millennia, antibiotics have been used to treat infections, although it was not until the last century or so that people discovered that infections were caused by bacteria. From 1945-1955, penicillin, streptomycin, chloramphenicol, and tetracycline ushered in the antibiotic age. However, today, many of these original antibiotics and most of their successors are largely ineffective due to antibiotic resistance. The use and misuse of antibiotics in both human and animal medicine has led to decreased efficacy of many common antibiotics due to bacteria’s ability to develop resistance.
Using sentiment analysis software and content analysis, this three-phase study sought to understand how online and traditional media discuss the topic of antibiotic use in livestock. Using a public opinion survey in the last phase, this study additionally sought to understand what effect framing of antibiotic use in livestock and the development of antibiotic resistant bacteria had on public opinion.
During phase one, Nuvi, a social media monitoring program, provided sentiment for each tweet and coded 64.8% of the content (n = 129) as negative compared to the 38.2% (n = 76) humans coded as negative. The contrast between human coders and Nuvi indicates there could be discrepancies between how Nuvi codes content and the way a human might interpret the content. No key influencer discussed antibiotic use in livestock positively. Findings suggest agricultural communicators should not rely completely on the output from Nuvi to evaluate how the public discusses issues related to agriculture, particularly controversial issues.
During phase two, a quantitative content analysis was conducted on three national U.S. newspapers from 1996 – 2017 and found three primary frames were used when discussing antibiotic use in livestock and antibiotic resistance. The content analysis also indicated that over 40% of the news articles contained no scientific source when communicating about this scientific topic. Based on the frames identified, some readers are being ill-informed about this topic and could be using this information in their decision making without having all of the facts. Science communicators should prioritize the inclusion of scientific sources in their writing as they communicate about complex, controversial topics.
In the final phase, a between-subjects experimental survey research design, 297 participants indicated their perceptions of antibiotic use in livestock and the development of antibiotic resistant bacteria before being randomly assigned to one of three conditions. Each condition was a mock Twitter account framed differently based on findings from phase two. After reading their assigned mock Twitter page, respondents indicated their trust of the information contained in the account, their information seeking behavior, demographics, and their support for antibiotic use in livestock. Using an ANCOVA, results indicated the frame influenced trust of information (F = 8.7, p < .05) and information seeking behavior (F = 4.48, p = .01) while support was not significant (F = 2.7, p = .07). Results suggest the blame frame has the greatest influence on shaping public opinion of antibiotic use in livestock and the development of antibiotic resistance.
This study allowed for the development of a more robust understanding as to what kinds of information are being communicated to the public regarding the topic. By identifying what messages are being communicated to the public, the researcher was then able to test the effects of these messages on the public. This study indicated the inclusion and omission of specific information can influence public opinion of antibiotic use in livestock and the development of antibiotic resistant bacteria
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
