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
Vehicle Speed Impacts of Occasional Hazard (Playground) Warning Signs
No full textThe main objective of this study was to estimate the speed impact of occasional hazard (playground) warning
(OHPW) signs along residential streets. Three types of data were collected at each of three study sites
approximately one month before and one week to one month after the installation of a pair of OHPW signs.
Vehicle speed data were collected with a pneumatic tube device. Manual observations were recorded, and focused
on the magnitude and location of the on-street parking and park and/or playground activities occurring at the study
sites. Linear regression analysis was used to estimate the change in mean vehicle speed associated with the
presence of the OHPW signs, while controlling for the effects due to activity levels on the streets and the
playgrounds. At one site the OHPW sign had no discernible effect on mean vehicle speeds, while at the other two
sites mean vehicle speeds decreased by 1.5 mph and 0.9 mph following installation of the OHPW signs.Civil Engineering Department, University of Minnesota; Iowa Local Technical Assistance Program, Institute for Transportation, Iowa State UniversityDavis, Gary; Knapp, Keith K.; Hourdos, John.

Eliciting goals of care in an academic nursing home
No full textObjectives
To identify enablers and barriers facing providers and staff in initiating Goals of Care (GOC) discussions with patients in the nursing home.
Design
Qualitative methods, one-on-one interviews. The interviews began with eliciting the participant’s definition of GOC. The open-ended questions were designed to assess recent experience and satisfaction with the participant’s role in the GOC discussion.
Setting
Nursing home.
Participants
We interviewed 23 nursing home staff and providers.
Measurements
Transcripts were qualitatively analyzed.
Results
Five themes emerged that were identified as barriers to discussing GOC: (1) Fear of legal ramifications; (2) Not enough education on how to have a GOC discussion; (3) Family not involved on a regular basis; (4) Time pressure; (5) Interdisciplinary team not involved. Five themes also emerged that were identified as enablers to the GOC discussion: (1) Education/experience with the GOC discussion; (2) Interdisciplinary team involved in the discussion; (3) Established trusting relationship with the patient/family/other staff; (4) Terminal diagnosis/hospice involvement; (5) Discussion occurs in-person.Conclusion
A major finding of these interviews is the lack of systematic attention to GOC in the nursing home setting. Since education and experience were identified as crucial to understanding GOC, more formal education and observed practice discussing GOC is needed for all staff. The outcomes of GOC discussions should be documented in the patient record and be accessible to all staff and communicated systematically to all staff. Addressing these barriers and facilitating these enablers to the GOC discussion will improve the care of nursing home patients. <br/
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
