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
Determination of the underwater acoustic properties of a towing tank for source radiated sound power measurement
No full textSound generated by marine vessels and structures, radiates into the marine environment. It is of great importance regarding the acoustic signature of naval vessels, and can have a dramatic impact on the behaviour and well-being of marine fauna. Additionally there is a need to make autonomous and remotely operated underwater vehicles as quiet as possible such that they can record the ocean soundscape, and not influence the behaviour of the marine life which they may be researching. Towing tanks offer a practical and controlled environment to measure and optimise the noise radiated by a ship at model scale. Additionally most underwater robotic vehicles are small enough to operate in a towing tank. However, sound measurements in towing tanks suffer from the effects of reverberation. This means sources acoustical properties measured in the tank can be significantly different to a measurement made in free field conditions. Current methods to overcome this method involve taking a measurement close to the source such the direct field is dominant over the reverberant field. However the measurement of reverberation distance is achieved with classical room acoustic equations which use an assumption of a diffuse field in their derivation. It is shown in this thesis, that the acoustic field inside a towing tank is not diffuse, and as such these classical room acoustic equations are not applicable to a towing tank. Additionally, limiting measurements to be within the direct field may cause the measurement to be in the near field of the source for low frequencies. In order to characterise the acoustic environment of a towing tank, and understand its impact on the acoustical properties of a source, an expression for the exact acoustical field inside a rectangular room with the boundaries and geometry of a towing tank is derived. To improve the computational cost of numerically evaluating this expression, an approximate form is derived, known commonly as the image source model. A spherical wave reflection coefficient is derived to improve the accuracy of the image source model. Impulse response measurements are undertaken in the Boldrewood towing tank, which are used to calibrate the damping in the image source model, through the tuning of the shear and compressional wave speeds in the plane wave reflection coefficient of the concrete wall of the tank. This method has produced an indirect way of measuring the shear and compressional wave speeds in the concrete walls of a water tank. A non-dimensional coefficient relating the power radiated by a point monopole source in a towing tank, to the surface averaged mean square pressure over the side wall of the tank is defined. This power coefficient can be used to predict the radiated power of a source in a tank, through measurement of the mean square pressure on the wall of the tank. The calibrated image source model is used to build a dataset of source radiated power and surface averaged mean square pressure for a large number of source locations. This enables the power coefficient to become statistically valid, and enable a prediction of power to be made with the measurement of surface averaged mean square pressure, with a quantifiable random error. Using the statistical analysis it is found that only 15 hydrophones are required to achieve a 98% probability of being within 3dB of the tanks mean value. This is a significant reduction in the number of hydrophone measurement locations used to measure power using the method of volume averaged mean square pressure in a diffuse field. The radiated power of an omnidirectional ITC1032 transducer is measured and validated against manufacturers specifications
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
