Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
Hybrid Nacelle Testing: Enhancing the Capabilities of Wind Turbine Nacelle Test Benches by Combining Virtual and Experimental Testing
The increasing size and complexity of modern wind turbines necessitates innovative testing methodologies to ensure their reliability and performance. Although ground-based nacelle testing facilities play a crucial role in the development process, they are facing challenges due to the growing demand for testing capacity. This thesis addresses these challenges by proposing and evaluating a novel hybrid testing approach that combines physical and virtual testing techniques.
A comprehensive literature review establishes the current state of the art in nacelle testing, highlighting key challenges and identifying the need for innovative solutions. The thesis then introduces a novel hybrid testing methodology that leverages partial load tests conducted on a physical test bench to develop and validate a high-fidelity simulation model. The validated virtual model is subsequently used to predict the full-load behavior of the wind turbine drivetrain, enabling the investigation of load ranges beyond the physical test bench's capabilities.
The framework for hybrid testing requires a virtual replica of the test bench. A systematic approach is proposed to develop and validate the virtual test bench model independently of a test specimen. This approach enables an accurate representation of the test bench related physical responses that can influence the overall system response during nacelle testing.
Using the developed virtual test bench model, the hybrid testing approach is demonstrated through a case study involving a 5 MW geared drivetrain subjected to parasitic load tests. Using measurements from partial load tests, the virtual model is validated and utilized to predict the full load response of the drivetrain. The accuracy of the virtual model in predicting various drivetrain responses at full load is evaluated.
Furthermore, the thesis investigates the influence of selecting different partial load ranges for model validation in predicting the full load response. By analyzing the nonlinear behavior of the drivetrain response, a systematic method is developed to determine the optimal partial load range for accurate full-load predictions. Finally, the nonlinearities in various drivetrain responses are characterized, providing valuable insights for developing hybrid test procedures for further drivetrain responses.
The hybrid testing concept aims to reduce the reliance on building larger and more expensive testing infrastructure and utilizes the already available testing facilities. Once matured, the novel hybrid testing approach has the potential to enhance the capabilities of existing test facilities, making them available for a wider range of wind turbine platforms
