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
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

An investigation of speech reception thresholds elevation pure-tone thresholds can not explain
Get PDFIt is well established that the biomarker most predictive of speech reception thresholds (SRTs) consists of pure-tone thresholds (PTTs). In general, the assumption is that an elevation of PTTs causes an elevation of SRTs. However, PTTs can explain ~60% of the variance of speech reception thresholds, and it remains controversial whether the remaining variance can be explained by subcortical phenomena such as cochlear synaptopathy or which part is caused by central processing deficits such as limited working memory, or a combination of both. To investigate the origins of SRT elevation which cannot be explained by PTT elevation, we employed a combination of subcortical and cortical measurements.
In the first section I will describe detailed audiometric screening of our cohort, in which we introduce two new approaches to studying the aspect of speech comprehension: the pure-tone normalized OLSA threshold (PNOT) and a post hoc analysis of variance. Using them, we show that age does not affect SRT beyond PTT. Furthermore, we found that cochlear synaptopathy explains a small but measurable amount of additional variance of SRT. In contrast, we found that the function of outer hair cells measured via pulsed DPOAE could explain a larger amount of additional variance.
In the second section, I will describe neuroelectric responses to phonemes recorded using a passive listening paradigm. Speech EEGs have been identified as an indicator of speech performance beyond PTT in hearing aid users. We confirm phoneme-evoked EEG response amplitude (PEA) as an indicator of speech comprehension. Specifically, PEA decreased with elevated SRT, PTT and increased age. We report here that temporal delays of phoneme-evoked EEG responses (PED) increase with age and PTT. The absolute duration of PED, its age-correlation, and the lack of PEA-lateralization suggest a predominantly thalamic generator of phoneme-evoked EEG responses. Most importantly, PED correlates with SRT and explains SRT-variance in quiet and in ipsilateral noise that PTT cannot. I will show that PED reflects both temporal fine structure (TFS) and temporal envelope (TENV) coding; thalamic activity may thus provide integrated information at the gate of the neocortex.
In the third section, I will expand the results of the previous two sections towards cortical speech processing. Cortical speech processing was investigated here using frequency-tagged MEG responses to speech in auditory scenes, including non-competitive and competing female and male voices. We found that attention alters cortical neural frequency-tagged responses. Furthermore, we have identified three factors that affect cortical speech processing. The first factor is the subject's age, which was correlated with increasing amplitude of cortical responses. The second factor is the delay of neural responses in the left hemisphere, which decreases with elevated SRT in noise. The neural response delay is particularly relevant when TFS coding is involved. Lastly, the third factor is the specificity of the neural response, which is linked to PNOT(quiet) and manifests as increased right-hemispheric activity and more stimulus-specific left-hemispheric responses to individual sentences. These findings can be explained as a combination of cortical and subcortical gating.
The combination of cochlear, subcortical and cortical factors measured in the same cohort provide a multi-dimensional picture of age-related hearing deficits. I sincerely hope that clinicians dealing with hearing deficits at the limits of pathology and the need to decide whether treatment is already necessary for a given patient, will benefit from the new perspectives opened here and possibly adopt new differentiated diagnostic tools. We have introduced new audiometric and neural measures which will hopefully advance further progress towards an objective measure of speech reception thresholds. Those more objective measures might in the future also enable more individualized therapeutic interventions
Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
