Personal Digital Twins and their Role in Epidemics Control. An IEEE Digital Reality White Paper
No full textSince the shift from nomadic life, to aggregation in clusters or cities, humanity has faced epidemics. It is the cluster of people that provides the fertile environment for viruses to jump from one host to the next, generating an epidemic. The geographical distance among clusters is a barrier to the spread of the epidemics; traveling from one locale to another was the only way to continue the spread. In the past, the epidemics spread along the commerce, maritime, and land pathways. Travel was slow and sporadic so an epidemic took years to become a pandemic. Today we have both bigger clusters (megacities and cities that on average are much bigger than the ones of the past) and much faster and denser traffic among clusters. This fuels both epidemics and pandemics
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
Gaming to Learn: A Pilot Case Study on Students Acceptance of Playing Video Games as a Learning Method
Full text linkThis paper presents a case study on playing video games as a method to support the delivery of a game development University module, describing the teaching methodology and presenting details on a ’gaming‘ for learning approach to support the module’s learning objectives. It presents the formulation of a theoretical framework to evaluate students acceptance of playing video games as a learning method, and the results of a pilot study using a modified Technology Acceptance Model.
The results revealed that gaming as a learning activity was positively perceived by students, finding this method engaging and relevant to their learning curriculum, playful, enjoyable, useful, easy to use, with positive attitudes and behavioural intentions to use. This pilot case study serves as a practical example of implementing video games to support learning, preparing the methodology for further research to understand students acceptance, and the effect on learning outcomes and knowledge acquisition
Utilising mobile game based learning methods effectively to support education
Full text linkThis paper is a response concerning the implications of scholarship of the article entitled "A critical review of 13 years of mobile game-based learning" by Giannakas et al. (in Educ Technol Res Dev 66:341–384, 2018). This response focuses on the key ideas presented in Giannakas et al. (2018) from a practical perspective, highlighting how practitioners, scholars and designers can use their findings to effectively utilise mobile Game Based Learning (mBGL) approaches to support and enhance learning. This response paper is discussing the value, impact and practical implications of Giannakas, et al. (2018) and possible future directions relevant to the use of smartphone enabled virtual reality to support mGBL
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
A cyber campus to support students experiencing barriers accessing education
No full textThere are many barriers hindering access to education for some students, significantly affecting their learning experience (Cross, 1981). To mitigate the effects of such barriers, e-learning technologies are widely used. One example of this is the use of cyber campuses. These are 3D environments where students can meet and share information, and synchronously communicate and collaborate (Prasolova-Førland et al., 2006). It has been suggested that the learning experience of students using these cyber campuses is related to their perceptions of presence, awareness, communication and sociability (De Lucia et al., 2009).
The educational capabilities of cyber campuses have been investigated thoroughly in the literature (Gregory et al., 2014). However, little is know about the extent to which cyber campuses can support students experiencing barriers hindering access to education. To investigate this, the SHU3DED (Sheffield Hallam University 3D Education) cyber campus was developed, and a mixture of quantitative and qualitative research was performed. A series of experimental studies were performed to i) evaluate the efficacy of SHU3DED to support online learning activities, ii) understand the barriers hindering access to Higher Education, and iii) ascertain the extent to which a cyber campus can alleviate some of these barriers and support students participate in online learning activities.
The findings of this research project revealed several barriers impeding access into Higher Education, together with a set of environment characteristics that contribute to the students’ online learning experience. The findings imply that a cyber campus can be a sound social space that supports participation in online learning activities for students experiencing situational and institutional barriers accessing education. The findings provide strong indications that a cyber campus has the potential mitigate some of the barriers that challenge or exclude students from accessing education, allowing them to participate in social online learning activities. As a result of this research project, a list of suggestions for the design and arrangement of cyber campuses have also been devised
