Gamification-based UML learning environment in virtual reality
No full textModeling is a key activity in conceptual design and system design which makes learning and understanding modeling languages like the Unified Modeling Language (UML) important. Many interactive UML learning applications exist and also gamification-based alternatives have been proposed in recent years to promote the engagement of learners. However, none of the existing approaches provide an immersive learning environment that can be used to increase interactivity while learning. As a consequence, existing UML learning applications cannot create a feeling of presence that can positively influence learning outcomes, and the potential of gamification is not fully exploited. To overcome this problem, in this demo paper, we present an immersive gamification-based UML learning environment in Virtual Reality (VR) to practice modeling class diagrams in an interactive way. The VR environment provides minigames and multi-viewpoint modeling features to learn creating class diagrams. The multi-viewpoint component highlights correspondences between a class diagram and a 3D model of an example system. The goal of this approach is to improve the learners' motivation, make the learning process an enjoyable experience, and boost learning outcomes
GaMoVR: Gamification-based UML learning environment in virtual reality
No full textOver the years, UML has become the de facto modeling language used in conceptual design and systems design leading to its adoption in computer science university courses. To improve learning outcomes, motivation, and fun of students learning about modeling UML and modeling in general, a variety of interactive learning applications has been presented over the years. However, so far, they fail to create immersive environments for the students missing out on drastically increasing engagement with the learning objectives. Hence, we present GaMoVR, a VR-based and gamified learning environment giving students learning about UML modeling an interactive and fun learning experience. Learning outcomes are further improved by utilizing gamification in the form of minigames encapsulating the modeling activity in an engaging and fun way. Furthermore, GaMoVR provides a multi-viewpoint modeling environment in which students can explore how a UML class diagram relates to a 3D model instancing the UML-modeled system
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
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
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
