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
The Amsterdam Foot Model: Advancing the clinical assessment of multi-segment foot kinematics during gait
Get PDFThe human feet are essential for our unique way of bipedal locomotion. A dysfunctional foot limits our mobility and consequently our participation in daily life. Hence, it requires careful clinical assessment before any treatment is provided to restore or maintain foot function. Musculoskeletal foot and ankle disorders can be evaluated with marker-based gait analysis. Many marker models have been developed to measure foot and ankle kinematics and several of these are used in a variety of clinical populations. However, a critical evaluation on whether the outcomes of current models actually represent the movement of the bony structures of the foot is still lacking. To further advance the clinical assessment of foot and ankle kinematic measurements during gait, measurement errors that affect the anatomical validity (i.e. accuracy) and reliability (i.e. precision) need to be quantified, and improved if required. Simultaneously, these models’ definitions and output have to align with the clinical perception of foot and ankle motions for a successful clinical application. In this thesis we aim to establish the most accurate and precise skin-marker-based method to measure clinically relevant foot and ankle kinematics during gait. First we explore and compare existing foot models. We show that the ankle angle and triceps surae muscle-tendon complex length are likely overestimated in a mono-segment foot model compared to a multi-segment foot model. Additionally, in chapter 3, we show that the two most-frequently used multi-segment foot models (i.e. the Oxford and Rizzoli Foot Models) provide different angular output for the same gait trials of normal and voluntarily pathological gait. In the second part of this thesis, we evaluate potential sources of measurement error in the Oxford and Rizzoli Foot Models to gain insight in their accuracy and precision. A well-known source of error within marker-based gait analysis are soft tissue artifacts, which are the relative motions of the skin-mounted markers with respect to their underlying bones. To measure these artifacts, we developed a low-dose loaded computed tomography scanning protocol including 10 scans with a total radiation dose that is similar to 1.5 times the dose of a single clinical foot and ankle scan (chapter 4). This protocol is used in chapter 5 to quantify the soft tissue artifacts, which are shown to be substantial and causing clinically relevant errors in multi-segment foot kinematics. Another potential source of measurement error is inconsistent marker placement. In chapter 6, we quantify the marker placement sensitivity and show that for both models each segment is highly sensitive to misplacement of at least one marker. In chapter 5 and 6, markers are identified that are most affected by soft tissue artifacts or inconsistent marker placement. The role of these markers within the model definitions should be reconsidered to improve the accuracy of the measurements and the robustness of the models to inconsistent marker placement. After these evaluation studies, we concluded that the evaluated models are affected by clinically relevant measurement errors that can lead to misinformation. Therefore, in part three of this thesis (chapter 7), we define a novel clinically-informed multi-segment foot model: the Amsterdam Foot Model. A foot and ankle expert panel was consulted to assure that the model definitions and its output align with the clinical perception. The model is explicitly based on minimizing the aforementioned measurement errors. Both types of errors were shown to be smaller in the Amsterdam Foot Model compared to the Oxford and Rizzoli Foot Models. Within the limitations of marker-based motion analysis, the clinically inspired Amsterdam Foot Model accurately and precisely measures foot and ankle kinematics during gait, while striving for an optimal combination of anatomical accuracy, clinical needs and practical applicability
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

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.
