Tempo graphs of 13 Beethoven piano sonatas (Op.13–Op.54) performed by 8 pianists
No full textThis dataset contains tempo graphs of 13 Beethoven piano sonatas (Op.13–Op.54) performed by eight pianists: Artur Schnabel, Wilhelm Backhaus, Wilhelm Kempff, Claudio Arrau, Friedrich Gulda, Alfred Brendel, Maurizio Pollini, and András Schiff. These graphs were generated using Vmus and illustrate tempo variation and average tempo across different sections of the sonatas as performed by the pianists.</span
Analysis of the Performance of Beethoven’s Piano Sonatas Composed Between 1798 and 1804 (Op.13 to Op.54)
No full textThis study aims to conduct an in-depth analysis of the performance recordings of 13 piano sonatas composed by Beethoven between 1798 and 1804 (Op. 13 to Op. 54), exploring the evolution over time of the performance styles of eight pianists from the 20th to the early 21st century in terms of tempo. This thesis first introduces the key collected and analytical methods of data used in this study, consisting of Vmus graphs and colour-coded spreadsheets. Subsequently, it explores the historical background of tempo treatment in 19th century performances, providing a context for the following analysis of performance styles. Then, this thesis continues by comparing and analysing the average tempo used by eight pianists in different phrases and segments of these works, providing a comprehensive interpretation of the variation of performance styles during this period. The analysis is mainly focused on three aspects, including the degree of acceleration, treatment of metronome mark, and trend analysis based on colour-coded spreadsheet. Meanwhile, this study investigates the individual characteristics of each pianist regarding tempo treatment. Finally, from the two perspectives, namely integrating historical performance methods with modern practices and innovative performance approaches, the author discusses how to create a Beethoven style that is consistent with contemporary aesthetics for today's audiences, demonstrating the potential for new interpretations of historical works in both the present and future
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
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
A Symplectic Numerical Power Flow Framework Based on Wave Finite-Element Method for Assembled Structural Systems
Full text linkIdentifying the propagation paths of dominant wave modes in complex assembled structure is critical for implementing wave-based vibration and noise control strategies, such as phononic band gaps. This paper presents a symplectic numerical framework to compute the wave-mode power flow in engineering assembled structures based on wave finite element method (WFEM). The power orthogonality among wave modes is explicitly formulated through the symplectic orthogonality (SO) and its adjoint form (SAO), and this formulation is further extended to the Zhong-Williams and lambda(phi) symplectic schemes. The generalized symplectic adjoint orthogonality (GSAO) and phi_SAO are subsequently proposed, providing a physically consistent basis for modal diagonalization and coherent wave propagation within the generalized symplectic eigenspace. These developments enable direct computation of the forced response and power flow entirely within the symplectic space, without reverting to the wave space. Six power-flow formulations are systematically compared and shown to yield consistent results on both beam and cylindrical shell structures. An electric motor housing is used as a case study, in which the proposed approach establishes a wave-mode power flow network. It is noted that the power-flow formulation relies on symplectic orthogonality defined for conservative WFEM systems and therefore cannot be directly applied to non-Hermitian systems
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
