Do we need permission to play in public? The design of participation for social play video games at play parties and ‘alternative’ games festivals

Play is a fundamental to being Human. It helps to make sense of the self, to learn, to be creative and to relax. The advent of video games challenged traditional notions of play, introducing a single player experience to what had primarily been a communal social activity. As technology has developed, communal play has found both online and real-world spaces within video games. Online streaming, multiplayer games and built-in spectator modes within games underpin online communal play experiences, whilst ‘alternative’ games festivals, play parties and electronic sports, provide real world spaces for people to meet, play and exchange knowledge relating to both playing and making video games. This article reports the study of social play events which bring people together in the same space to explore video games making and playing. Expert interviews with curators, and event facilitators provides qualitative data from which design processes are formalised into a ‘model of participation’ of social play. Four key areas of balance are proposed as core considerations in supporting participation in event design. The study of these events also suggests that their design and fostering of participation has the potential to evoke cultural change in game making and playing practices

Updating the UK’s code for fiscal stability

The 1998 Code for Fiscal Stability sets out the framework within which UK fiscal policy is now set. While having such a code does not make it easier for a Government to meet its fiscal objectives, it may improve the economic credibility of the policy process. To date the Code has generally worked well, and in any case many of the Treasury’s practices exceed the minimum requirements of the Code. However, improvements could be made in the light of recent experiences. In particular it would be preferable for less emphasis to be placed on the precise forecasts for fiscal aggregates and greater emphasis to be placed on the magnitude of the risks to those forecasts. Using the projections contained in the March 2004 Budget, and information on the size of errors made in the past, we estimate that there is now a 60% chance that the Chancellor’s “golden rule” will be met without further tax increases or spending cuts. This compares to 74% for the forecast made by the Treasury 12 months earlier. As well as clarifying how cautious forecasts are, the uncertainty surrounding projections for fiscal aggregates also has implications for the way in which progress towards any fiscal rules should be interpreted

Separation of gas mixtures by centrifugation

Magnetohydrodynamic (MHD) centrifuge utilizing electric currents and magnetic fields produces a magnetic force which develops supersonic rotational velocities in gas mixtures. Device is superior to ordinary centrifuges because rotation of gas mixture is produced by MHD force rather than mechanical means

A three person poncho and a set of maracas:designing Ola De La Vida, a co-located social play computer game

Events that bring people together to play video games as a social experience are growing in popularity across the western world. Amongst these events are ‘play parties,’ temporary social play environments which create unique shared play experiences for attendees unlike anything they could experience elsewhere. This paper explores co-located play experience design and proposes that social play games can lead to the formation of temporary play communities. These communities may last for a single gameplay session, for a whole event, or beyond the event. The paper analyses games designed or enhanced by social play contexts and evaluates a social play game, Ola de la Vida. The research findings suggest that social play games can foster community through the design of game play within the game itself, through curation which enhances their social potential, and through design for ‘semi-spectatorship’, which blurs the boundaries between player and spectator thus widening the game’s magic circle

Applying concepts of fuzzy cognitive mapping to model IT/IS investment evaluation factors

The justification process is a major concern for many organisations that are considering the adoption of Information Technology (IT) and Information Systems (IS), and is a barrier to its implementation. As a result, the competitive advantage of many companies is being put at risk because of management's inability to evaluate the holistic implication of adopting new technology, both in terms of on the benefit and cost portfolios. This paper identifies a number of well-known project appraisal techniques used in IT/IS investment justification. Furthermore, the concept of multivalent, or fuzzy logic, is used to demonstrate how inter-relationships can be modeled between key dimensions identified in the proposed conceptual evaluation model. This is highlighted using fuzzy cognitive mapping (FCM) as a technique to model each IT/IS evaluation factor (integrating strategic, tactical, operational and investment considerations). The use of an FCM is then shown to be as a complementary tool which can serve to highlight interdependencies between contributory justification factors

Cotton spinning to climbing gear: practical aspects of design evolution in Lancashire and the North West of England

This article looks at the role of path dependency in the design of outdoor clothing and equipment, from the perspective of changing and overlapping industrial clusters in Lancashire and Sheffield, from the 1960s. It demonstrates that, unlike the fashion market, design in mountaineering clothing and equipment was originally based heavily upon functionality and hence on user innovation. It shows that skills and knowledge which evolved during the industrial revolution, in both industrial areas, were vitally important to the development of internationally competitive mountaineering equipment firms. It was, however, the way in which these sources of knowledge were combined with sporting expertise that contributed to the design of innovative functional products. In addition, fundamental changes occurred in the relationship between manufacturers and their customers and these were vital to the success of this process, marking a departure from past practice

Shock temperatures in calcite (CaCO3): Implication for shock induced decomposition

The temperatures induced in crystalline calcite upon planar shock compression (95–160 GPa) are reported from two-stage light gas-gun experiments. The temperatures are obtained fitting 6-channel optical pyrometer radiances in the 450 to 900 nm range, to a Planck radiation law temperature varied from 3300 to 5400 K. Calculations demonstrate that the temperatures are some 400 to 1350 K lower than if either shock-induced melting and/or disproportionation of calcite behind the shock front was not occurring. Here calcite is modeled as disproportionating into a molecular liquid, or a solid CaO plus CO2 gas. For temperature calculations, specific heat at constant volume for one mole of CO2 is taken to be 6.7R as compared to 9R in the solid state; whereas calcite and CaO have their solid state values (15R and 6R). Calculations also suggest that the onset of decomposition in calcite to CaO and CO2 during loading occurs at ~75±10 GPa, along the Hugoniot whereas decomposition begins upon unloading from 18 GPa. The 18 GPa value is based on comparison of VISAR measurements of particle velocity profiles induced upon isentropic expansion with one-dimensional numerical simulation
