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
Considerations in Technology Transfer Concerning Biopharmaceuticals: The University Perspective
No full textThe US pharmaceutical industry continues to face a number of challenges which include decreasing returns, declining sales, increasing development costs, the threat of price controls, an increasingly risk averse FDA, lack of internal pipeline diversity, patent expirations, and industry consolidation. With fewer truly innovative drug discovery programs being initiated internally, big pharma is more and more reliant on small, development stage biotech companies for their future product pipelines. Biotech companies however are facing challenges themselves, not the least of which is the paucity of true early-stage capital to fund technology development, pre-clinical drug discovery and product platform innovation. As a result, top tier research universities have had to step up to address the challenge of supporting the translational research needed to fill the growing gap between fundamental research undertaken within the academy and the innovation that fuels early stage companies and the future of therapeutics, diagnostics and medical device discovery and development. At UC Davis, we see an important element of our public mission being to transform cutting edge biological research into products or services that can positively change the lives of those in our community and create economic impact in California and beyond. Effective and efficient technology commercialization processes lie at the heart of how we are working to transform innovation into impact
Use of a thermodynamic cycle simulation to determine the difference between a propane-fuelled engine and an iso-octane-fuelled engine
Get PDFA thermodynamic cycle simulation of the four-stroke spark-ignition engine was
used to determine the effects of variations in engine design and operating parameters on
engine performance and emission characteristics. The overall objective was to use the
engine cycle simulation to determine the difference between a propane-fuelled and an
iso-octane-fuelled engine for the same operating conditions and engine specifications.
A comprehensive parametric investigation was conducted to examine the effects
of variations in load, speed, combustion duration, spark timing, equivalence ratio,
exhaust gas recycle, and compression ratio for a 3.3 liter, Chrysler Minivan, V 6 engine
operating on propane. Parameters were selected for the analysis. Variations in the brake
specific fuel consumption, brake specific NOx emissions, and mean exhaust temperature
were determined for both the propane-fuelled and the iso-octane-fuelled engines.
Brake specific fuel consumption and mean exhaust temperature values for the
propane-fuelled engine were consistently lower (3 to 5 %) than the corresponding values
for the iso-octane-fuelled engine. Fuel structure did not have a significant effect on brake
specific nitric oxide emissions.
Predictions made from the simulation were compared with some of the available
experimental results. Predicted brake torque and brake power showed acceptable
quantitative agreement (less than 10 % variation) in the low engine speed range (1,000 to
3,000 rpm) and similar trends with the available experimental data
