Collaborative virtual gaming worlds in higher education
There is growing interest in the use of virtual gaming worlds in education, supported by the increased use of multiâuser virtual environments (MUVEs) and massively multiâplayer online roleâplaying games (MMORPGs) for collaborative learning. However, this paper argues that collaborative gaming worlds have been in use much longer and are much wider in scope; it considers the range of collaborative gaming worlds that exist and discusses their potential for learning, with particular reference to higher education. The paper discusses virtual gaming worlds from a theoretical pedagogic perspective, exploring the educational benefits of gaming environments. Then practical considerations associated with the use of virtual gaming worlds in formal settings in higher education are considered. Finally, the paper considers development options that are open to educators, and discusses the potential of Alternate Reality Games (ARGs) for learning in higher education. In all, this paper hopes to provide a balanced overview of the range of virtual gaming worlds that exist, to examine some of the practical considerations associated with their use, and to consider their benefits and challenges in learning and teaching in the higher education context

Making sense of assets: Community asset mapping and related approaches for cultivating capacities
This working paper critically reviews some main aspects from asset based approaches highlights key strengths and weaknesses for future research/development. Drawing on a large body of reports and relevant literature we draw on different theoretical traditions and critiques, as well as practices and processes embedded within a broad range of approaches including, widely acknowledged frameworks such Asset Based Community Development (ABCD), Appreciative Inquiry (AI), Sustainable Livelihood Approaches (SLA) and Community Capitals Framework (CCF). Although these are presented as distinct approaches, there is a sense of evolution through them and many of them overlap (in terms of both theories and methodologies). We also include emerging frameworks, including geographical, socio-spatial, visual and creative approaches, stemming from a number of projects within AHRCâs Connected Communities programme and additional collaborations

Virtual reality and its role in removing the barriers that turn cognitive impairments into intellectual disability
Early expectations of the contribution that virtual reality (VR) could make to education far exceeded actual applications. This was largely due to the initial immaturity of the technology and a lack of evidence base on which to base design and utilisation. While the early developments in computer based learning largely concentrated on mainstream education, leaving those with special needs behind, the potential of VR as an educational tool was exploited for those with intellectual disabilities right from the start. This paper describes the empirical evidence that has contributed to the development of educational virtual reality for those with intellectual disabilities: studies on transfer of learning from the virtual to the real world; how teachers might support those using VR; the design of virtual environments and what input/control devices best facilitate use of desktop VR. Future developments and ethical issues are also considered
The co-evolution of the âsocialâ and the âtechnology": a netnographic study of Social movements in virtual worlds
Virtual worlds provide new forms of social interaction. They offer alternative spaces where social functions can be carried out in online three-dimensional virtual environments. One social phenomenon which has moved into the virtual world is the social movement, which are an important means of bringing out social, cultural and political changes through collective action. These social movements exist in an immersive technological ecosystem which is constantly evolving as designers release patches which change the way users âliveâ within these environments. Using a biography of artifacts approach, we explore not just the evolution of the technological artifact itself (the virtual world), but also its co-evolution with the social phenomena (a social movement). Using Netnography, a modified version of ethnography, and actornetwork theory, we explore a social movement in World of Warcraft, and observe how it evolves over time as changes to the virtual world are implemented
Poverty, institutions and interventions: a framework for an institutional analysis of poverty and local anti-poverty interventions
At a time when technological innovations are making our world increasingly smaller and our production systems are becoming increasingly more efficient, the benefits of economic growth and development as a whole have not been able to reach all of society. Indeed, many poor countries, characterised by their disadvantageous position in the global society and continuously plagued by weak governments, internal strife and natural disasters have missed out on many of the benefits of growth and development. Within countries that do gain advantage from the various developments of globalisation, significant groups continue to be excluded from the benefits of this new-found prosperity. It is quite significant that a generalised conclusion such as this is still a reality at the turn of the century, despite decades of national and international effort to promote development and combat poverty.
Toward an Aesthetics of New-Media Environments
In this paper I suggest that, over and above the need to explore and understand the technological newness of computer art works, there is a need to address the aesthetic signiïŹcance of the changes and effects that such technological newness brings about, considering the whole environmental transaction pertaining to new media, including what they can or do offer and what users do or can do with such offerings, and how this whole package is integrated into our living spaces and activities. I argue that, given the primacy of computer-based interaction in the new-media, the notion of âornamentalityâ indicates the ground-ïŹoor aesthetics of new-media environments. I locate ornamentality not only in the logically constitutive principles of the new-media (hypertextuality and interactivity) but also in their multiform cultural embodiments (decoration as cultural interface). I utilize Kendall Waltonâs theory of ornamentality in order to construe a puzzle pertaining to the ornamental erosion of information in new-media environments. I argue that insofar as we consider new-media to be conduits of âreal-lifeâ, the excessive density of ornamental devices prevalent in certain new-media environments forces us to conduct our inquiries under conditions of neustic uncertainty, that is, uncertainty concerning the kind of relationship that we, the users, have to the propositional content mediated. I conclude that this puzzle calls our attention to a peculiar interrogatory complexity inherent in any game of knowledge-seeking conducted across the infosphere, which is not restricted to the simplest form of data retrieval, especially in mixed-reality environments and when the knowledge sought is embodied mimetically
How a Diverse Research Ecosystem Has Generated New Rehabilitation Technologies: Review of NIDILRRâs Rehabilitation Engineering Research Centers
Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a âtotal approach to rehabilitationâ, combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970âs, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program
Training Competences in Industrial Risk Prevention with LegoÂź Serious PlayÂź: A Case Study
This paper proposes the use of the LegoÂź Serious PlayÂź (LSP) methodology as a facilitating tool for the introduction of competences for Industrial Risk Prevention by engineering students from the industrial branch (electrical, electronic, mechanical and technological engineering), presenting the results obtained in the Universities of Cadiz and Seville in the academic years 2017â2019. Current Spanish legislation does not reserve any special legal attribution, nor does it require specific competence in occupational risk prevention for the regulated profession of a technical industrial engineer (Order CIN 351:2009), and only does so in a generic way for that of an industrial engineer (Order CIN 311:2009). However, these universities consider the training in occupational health and safety for these future graduates as an essential objective in order to develop them for their careers in the industry. The approach is based on a series of challenges proposed (risk assessments, safety inspections, accident investigations and fire protection measures, among others), thanks to the use of âgamificationâ dynamics with LegoÂź Serious PlayÂź. In order to carry the training out, a set of specific variables (industrial sector, legal and regulatory framework, business organization and production system), and transversal ones (leadership, teamwork, critical thinking and communication), are incorporated. Through group models, it is possible to identify dangerous situations, establish causes, share and discuss alternative proposals and analyze the economic, environmental and organizational impact of the technical solutions studied, as well as take the appropriate decisions, in a creative, stimulating, inclusive and innovative context. In this way, the theoretical knowledge which is acquired is applied to improve safety and health at work and foster the prevention of occupational risks, promoting the commitment, effort, motivation and proactive participation of the student teams.Spanish Ministry of Science, Innovation and Universities / European Social Fund: RamĂłn y Cajal contract (RYC-2017-22222
On Characterizing the Data Movement Complexity of Computational DAGs for Parallel Execution
Technology trends are making the cost of data movement increasingly dominant,
both in terms of energy and time, over the cost of performing arithmetic
operations in computer systems. The fundamental ratio of aggregate data
movement bandwidth to the total computational power (also referred to the
machine balance parameter) in parallel computer systems is decreasing. It is
there- fore of considerable importance to characterize the inherent data
movement requirements of parallel algorithms, so that the minimal architectural
balance parameters required to support it on future systems can be well
understood. In this paper, we develop an extension of the well-known red-blue
pebble game to develop lower bounds on the data movement complexity for the
parallel execution of computational directed acyclic graphs (CDAGs) on parallel
systems. We model multi-node multi-core parallel systems, with the total
physical memory distributed across the nodes (that are connected through some
interconnection network) and in a multi-level shared cache hierarchy for
processors within a node. We also develop new techniques for lower bound
characterization of non-homogeneous CDAGs. We demonstrate the use of the
methodology by analyzing the CDAGs of several numerical algorithms, to develop
lower bounds on data movement for their parallel execution
