Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Risk Assessment for the Transmission of Foot and Mouth Disease via Movement of Swine and Cattle Carcasses from FMD-infected Premises to a Disposal Site
Full text linkThe present risk assessment proactively evaluated the risk of infecting susceptible livestock by
the movement of Foot and Mouth Disease (FMD) infected carcasses (swine and cattle) from
FMD infected premises. The risk assessment evaluated the most up to date available science and
solicited opinion from experts when data was lacking. This risk assessment is proactive in nature
and the scenarios, pathways and depopulation practices assessed were based on the current
practices and regulations applicable during an animal disease outbreak in the US. The
characteristics, types of conveyance methods, and equipment used to transport the infected
carcasses were provided from expert opinion and verified through site visits. Different modeling
techniques were used to estimate the number of infected animals during a FMD outbreak at
various time intervals, the total time estimated from infection to depopulation and the total
amount of FMD virus (FMDv) contained in a disposal truck. The main outcomes of the risk
assessment should be reviewed if needed as new data becomes available in the future.
Risk estimation: The risk of FMD infection of susceptible livestock associated with the
movement of swine and cattle carcasses from FMD infected premises to a disposal site during a
FMD outbreak in the United States is negligible when using a standard rendering truck (tailgate
sealed and tarp cover) and a Bio-Zip bag, and between negligible and low when using a
standard rendering truck or a roll-off /dump truck with a Bio-Zip bag. The risk level in other
scenarios (uncovered standard rendering trucks, uncovered roll-off/dump trucks, covered rolloff/
dump trucks and a liner) is between moderate and high.
Main results: Time for FMD detection was estimated by a disease spread model to be between
4-10 days for swine and beef cattle and 3-9 days for dairy cattle premises of different sizes. Total
time from infection to depopulation (including detection and confirmation) for the first FMD
infected case was estimated to be between 10-15 days for swine, 8-12 days for dairy and 10-14
days for beef cattle premises. Total time estimated for subsequent FMD cases was between 7-12
days for swine, 6-9 for dairy and 8-11 days for beef cattle premises. Most of the animals (>65%
for the first case and >81% for subsequent cases) were viremic at the time of depopulation. The
average concentration of FMDv in a carcass in experimental inoculation studies was 103 Plaque-
Forming Unit per gram (PFU/g) for a pig carcass and 106 PFU/g for a cattle carcass. The total
amount of infected carcasses moved to the disposal site (relative to the size of the animal carcass
and the capacity of the truck trailer) was between 23-390 cattle carcasses and 117-780 pig
carcasses per truck. Any small amount of body fluids (1 mL) would contain virus that is equal
and greatly exceeds the infective dose by oral and inhalation route for pigs and cattle. The
likelihood that swine and cattle carcasses moved from FMD positive premises will contain an
infective dose was high. The use of a Bio-Zip bag in a standard rendering truck (tailgate sealed
and tarp cover) reduces the likelihood of leakage, spillage and aerosolization to negligible.This project was developed in funded through a sub-award with West Texas A&M University through USDA-APHIS and DHS.Slingluff, Jamie; Sampedro, Fernando; Goldsmith, Timothy J..

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
