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
Structure and dynamics in framework materials
Get PDFThis thesis details a study of framework materials of the AM2O8 and AM2O7 families, which are of interest due to their unusual thermal expansion properties, phase transitions and often complex structures. The combination of results from NMR and diffraction techniques has enabled several new insights into the structure and dynamics to be made. Chapter 1 reviews the literature on negative thermal expansion materials that are of relevance to this project. Chapter 2 outlines the background to the key experimental techniques employed in this work. Chapter 3 outlines 17O isotopic enrichment techniques and qualitative results for several AM2O8 phases. 17O NMR results for cubic ZrW2O8 including variable temperature spectra and 2DExchange Spectroscopy (EXSY) are presented. The a / ß phase transition and low temperature oxygen mobility in ZrW2O8 are investigated. NMR results enabled the determination of a mechanism of oxygen exchange different to the previously suggested mechanism, which is disproved. The results of in situ diffraction experiments to investigate phase transitions inZrMo2O8 are also presented. 17O enriched samples of cubic-, trigonal- and LT- ZrMo2O8 samples were prepared, and their 17O NMR spectra recorded. Chapter 4 describes quantitative 17O NMR studies used to characterise oxygen dynamics inZrW2O8. The results of a range of NMR experiments, including a combination of 1D EXSY and saturation recovery experiments, are interpreted to give a measure of the rate and the activation energy for oxygen exchange. The experiments and derivation of the required theoretical background are detailed. Chapter 5 outlines a range of structural studies on AM2O7 materials. The room temperature superstructure of HfP2O7 is determined using a combination of X-Ray and neutron diffraction.31P NMR is reported for the high temperature phases of HfP2O7 and ZrP2O7 for the first time. The symmetry of the high temperature phase of HfP2O7 is investigated by Rietveld refinement of neutron diffraction data. Unusual effects in the 51V NMR spectra of HfV2O7 and ZrV2O7 are also reported. Chapter 6 outlines preliminary work on computational methods to investigate the structural dependence of the 31P NMR chemical shift of pyrophosphate materials. DFT calculations of NMR parameters were carried out, and a methodology developed for the derivation of suitable theoretical model structures
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
