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

Implementing Milestones: A Qualitative Analysis of Impact
No full textBackground: Changes to programs of assessment following the shift to milestones-based assessment in the Next Accreditation System have not been fully characterized. Better understanding is critical to helping programs across all specialties capitalize on emerging best practices and overcome shared challenges to meaningful milestones implementation.
Methods: Semi structured interviews were conducted with 15 residency program directors or associate program directors in 6 medical specialties at 8 academic medical centers. Questions explored four areas: 1) reviews of pre-milestones assessment programs to prepare for milestones-based assessment and reporting; 2) what programs retained from previous assessment efforts; 3) what programs added or changed from previous assessment efforts; and 4) what was the impact of the shift to milestones-based assessment on the program. Thematic analysis was used to identify codes, sub-themes, and themes.
Results: Four themes were defined in the data: 1) challenges to effective implementation; 2) adaptability and making milestones work; 3) value and utility of assessment changes; and 4) accountability and transparency to society, program, and residents.
Conclusions: Three of the four themes identified elaborated the impact of the shift to milestones, such as identification of gaps in curricula or the ability to obtain previously lacking objective performance data. Program leaders desired more guidance and support in redesigning programs of assessment but are resourceful in adapting milestones to their context. This underscores the importance of supporting programs with practical strategies and resources to support success in milestones-based assessment.Master of Medical Sciences in Medical Educatio
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

The Ancillary Learning Resources Used by Medical Students for Self-Directed Learning
No full textThe Internet is an important source of medical information. It not only increases the scope of available medical resources, but also provides opportunities that support self-directed learning and the individual learning preferences of medical students. This study identifies the common online learning resources used by medical students and their perceptions regarding the use of online resources for learning.
This study was conducted at a South African medical school which offers a six-year medical degree program. A mixed methods study design was used. The study consists of two phases, an initial qualitative phase that used focus group discussions, and a subsequent quantitative phase that used an online survey. The focus group discussions informed the design of the survey. This survey was distributed to medical students in years three to six.
A total of 19 medical students participated in the focus group discussions. The focus group discussions highlighted that online resources provided students with flexibility regarding how information could be acquired and also facilitated the learning process. However, there were concerns regarding credibility, depth and contextual relevance of some online resources. From 201 survey responses, 83% of respondents used online learning resources as often or more often than university-provided materials. The most popular resources were YouTube (91%), UpToDate (86%) and Medscape (75%), of which UpToDate and YouTube were found to be more useful than textbooks (p < .001). Students used these resources to establish a basic conceptual understanding of a clinical topic (79%). Using these was also considered time efficient (73%).
Online resources complement student learning. However, there are concerns regarding resource credibility, depth and contextual relevance. Medical schools should consider advising students on the rational and effective use of these online resources and should consider assisting in the development of information seeking and management so that students can successfully meet their learning goals.Master of Medical Sciences in Medical Educatio
