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
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

Disease management and latent choices
Get PDFThis dissertation consists of three independent essays in the field of health economics. The first essay analyzes factors influencing the initial treatment choice of inpatients with severe hypertension. A thorough analysis of treatment choice has been largely overlooked in the hypertension literature, and few studies of any disease have conducted comprehensive multivariate analyses on treatment choices using such a diverse array of socioeconomic variables and hospital locations. According to the results, characteristics other than morbidity affect the type of treatment received; indicating public policy could improve care. The second essay analyzes the effect that a patient's reference point has on her perceived effectiveness of subsequent treatment. One commonly used measure of treatment effectiveness for conditions where treatments are palliative, and clear objective symptoms do not exist, is self-reported changes in disease status. Factors such as treatment history provide a reference point that may influence patients' expectations of how effective further treatment might be. Therefore, decisions about whether to proceed with additional treatment, as well as perceptions of how effective that treatment is, may be influenced by this point. Although there is an extensive literature on how patient expectations influence treatment outcomes, work testing how expectations depend on these reference point factors appears to be missing. The results indicate that these factors influence perceived treatment effectiveness. The final essay focuses on missing and ambiguous observations in a dataset with binary dependent variables. The ability to reallocate these responses could aid in the correction of potentially biased estimates. Using the "latent-choice multinomial logit model" (LCMNL), it is possible to determine whether these incomplete responses are more likely to belong to another outcome. Simulations of this model are performed to determine whether the estimated conditional probabilities are accurate enough to evaluate the likelihood that any given observation belongs to a particular outcome, and whether doing so improves parametric estimation. Tests imply that the reclassifications indicated by the LCMNL's conditional probabilities are accurate. The best method for dealing with ambiguous observations in empirical analysis is also assessed. Results indicate that the best method depends on the source of the ambiguit

Academic Success and Initial Labor Market Outcomes for Pharmacy Graduates
Get PDFPurpose: This study examines the relationship between academic success and labor market outcomes among graduating pharmacy students. Unlike previous studies, this paper characterizes labor market outcome not only as an individual’s starting salary, but also whether or not the student had a position secured at the time of graduation, whether or not a signing bonus was received, and the setting in which (s)he will practice. Methods: A standard exit survey was administered to graduating Doctor of Pharmacy students at a Midwestern, public university within two weeks of graduation. The relationship between academic success and initial labor market outcome was assessed using cross-tabulations, chi-square and Fisher exact tests. Results: There were no significant relationships between grade point averages and signing bonuses, starting salaries or employment offers. Students with higher grade point averages were less likely to work in chain community pharmacies, and more likely to work in a hospital or other health-system setting. Conclusions: The relationships between academic and direct measures of labor market outcomes (salary and bonuses) were not necessarily positive, as standard economic theory predicts. Rather, the relationship is indirect, as it appears that students with greater academic success obtained employment in more clinical settings, which carry a different mix of pecuniary and non-pecuniary benefits.Murphy, Sean; Naughton, Cynthia; Friesner, Dan.
