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
External validation of the ASTRAL and DRAGON scores for prediction of functional outcome in stroke
No full textBackground and Purpose - ASTRAL (Acute Stroke Registry and Analysis of Lausanne) and DRAGON (includes dense middle cerebral artery sign, prestroke modified Rankin Scale score, age, glucose, onset to treatment, National Institutes of Health Stroke Scale score) are 2 recently developed scores for predicting functional outcome after acute stroke in unselected acute ischemic stroke patients and in patients treated with intravenous thrombolysis, respectively. We aimed to perform external validation of these scores to assess their predictive performance in the large multicentre Safe Implementation of Thrombolysis in Stroke-International Stroke Thrombolysis Register. Methods - We calculated the ASTRAL and DRAGON scores in 36 131 and 33 716 patients, respectively, registered in Safe Implementation of Thrombolysis in Stroke-International Stroke Thrombolysis Register between 2003 and 2013. The proportion of patients with 3-month modified Rankin Scale scores of 3 to 6 was observed for each score point and compared with the predicted proportion according to the risk scores. Calibration was assessed using calibration plots, and predictive performance was assessed using area under the curve of the receiver operating characteristic. Multivariate logistic regression coefficients for the variables in the 2 scores were compared with the original derivation cohorts. Results - The ASTRAL showed an area under the curve of 0.790 (95% confidence interval, 0.786-0.795) and the DRAGON an area under the curve of 0.774 (95% confidence interval, 0.769-0.779). All ASTRAL parameters except range of visual fields and all DRAGON parameters were significantly associated with functional outcome in multivariate analysis. Conclusions - The ASTRAL and DRAGON scores show an acceptable predictive performance. ASTRAL does not require imaging-data and therefore may have an advantage for the use in prehospital patient assessment. Prospective studies of both scores evaluating the impact of their use on patient outcomes after intravenous thrombolysis and endovascular therapy are neede
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
Amber ( كَهرمَانْ ) : Interactive Installation Experience Mixed of Video and 3D Projection Mapping Installation
No full textThis capstone project proposes an approximately 120-seconds 3D projection mapping of a combination of 3D and 2D animated content. The concept of the project is entertainment as it is presented as a live interaction with the audience. The interaction will be based on an animated fiction scenario about a psychological concept of a schizophrenic human experience to be visualized. This project is under the installation art category which considers as an Interactive art piece. The project will comprise pre-production, production, and post-production stages. The first part of the capstone thesis (VDP 450) consists of two chapters. The first chapter provides an introduction with background information, brief history, and significance of the project, while the second chapter contains the project concept, synopsis, Visual Treatment, Concept Art, Mood Board, and Wireframe
NIMBO
No full textThis capstone project proposes a short, animated film (2-3 mins) about a story that revolves
around a young boy and a cloud maker, who go through a journey of discovery during the
transition into adulthood. This film is ultimately about imagination, and the hardship that are part
of growing up and losing touch with youthfulness. This project targets all demographics, and
encourages children to embrace their imagination, and adults to nurture it. This film will go
through all the pre-production, production and post production phases of animation, including
research on character design, environment design and depicting emotions on screen. Finally,
there are two chapters in the first part of the capstone thesis. Chapter 1 contains an introduction,
brief background information and the significance of the project, while chapter 2 contains the
script, treatment, synopsis, concept, and storyboard
Xenophobia
No full textThis capstone project proposes an Augmented Reality experience as Transmedia project about the different world of forest at night. It will be presented in a visual platform with some sound effects. The user interacts with the visuals that is viewed on a big LED screen. The camera detects the position of the user. The first phase is to write the story and then to make it visualized through a suitable program. This capstone thesis contains three chapters. Chapter one is about the idea, background, and significance of the story. Chapter 2 includes longline, synopsis, character description, treatment, concept art and wire frame. Chapter 3 discuss the final production of the whole Augmented Reality experience by representing some visuals from the experience
