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
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
Vehicle dynamics modeling and simulation including empirical nonlinear tire elements with artificial intelligence using native code MotionSim integrated into Simulink environment
No full textLocation: The 7th International Conference on Multibody System Dynamics, June 9-13, 2024, Madison, WI, USAEasyChair Preprint 13544The development of a multibody vehicle model, generated using the MotionSim and integrated into to the Simulink environment, has been described in this study. MotionSim is a collection of codes, which has been developed in the Matlab, specifically to model multibody systems without physical definitions utilizing general coordinates, as well as to allow one the ability to modify the source code to include any special constraints or elements that may be required.
MotionSim code has then been integrated into to the Simulink environment, providing a pictorial representation of physical signals and methods. With the flexibility of Matlab’s toolboxes and MotionSim being native codes, integrating Artificial Intelligence into multibody simulations can easily be achieved. In this study, the actual tire data by the Calspan Institute, providing tire testing data to Formula SAE teams, has been fitted to neural network models, which predict the tire lateral and longitudinal forces based on the slip angle and ratio. All this information is put together and can be simulated in the Simulink environment.
The general multibody solver is encapsulated into the full vehicle Simulink model block. This allows the integration of control systems into the model, which can include simple elements such as a driver model utilizing a simple PID loop that may control the vehicle in the specified scenario. It also allows the inclusion of control and simulation of active suspension elements such as continuously variable dampers and stability control
3D biomechanical simulation of human walking: Empirical data and inverse dynamics integration
No full textLocation: The 7th International Conference on Multibody SystemDynamics, June 9-13, 2024, Madison, WI, USAEasyChair Preprint 13393, version 1This study leverages 3D human modeling and gait analysis using multibody dynamics to enhance the understanding of human locomotion. By integrating detailed biomechanical models with computational methods, it provides a comprehensive analysis of gait patterns, overcoming traditional limitations. The model segments the body into various rigid parts, connected by spherical joints, to simulate realistic movements. Accurate foot-ground contact dynamics are modeled using a Hertzian-based normal contact force with dissipated damping and a modified Coulomb friction model, with a CT scan of a complete foot improving precision. This advanced approach significantly enhances the fidelity of human movement simulation and offers potential for clinical applications in diagnosing and treating gait disorders
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
