Moving tales, exploring narrative strategies for scalable locative audio drama.

This paper reports on a recent collaboration between the Lansdown Centre for Electronic Arts at Middlesex University and the BBC Radio Drama Department, which was designed to investigate the narrative possibilities of locative media in a drama context. The locative drama Scratch is the first outcome of an ongoing research project, Locating Drama, whose aim is to investigate and develop narrative strategies that take full advantage of the current generation of GPS enabled portable computing devices for audio drama. In particular, we are exploring content and modes of interaction, which, while based on location awareness are not in any way site-specific allowing users to experience the drama in a location of their choice. We will refer to this approach as translocational as it allows the translation of locative media experiences to a wide variety of spaces. The translocational approach is of particular interest to broadcasters as it is more scalable than a site-specific paradigm, opening the possibility of downloadable location-aware podcasts featuring professionally authored content for a wide audience

Frameshift Mutagenesis and Microsatellite Instability Induced by Human Alkyladenine DNA Glycosylase

Human alkyladenine DNA glycosylase (hAAG) excises alkylated purines, hypoxanthine, and etheno bases from DNA to form abasic (AP) sites. Surprisingly, elevated expression of hAAG increases spontaneous frameshift mutagenesis. By random mutagenesis of eight active site residues, we isolated hAAG-Y127I/H136L double mutant that induces even higher rates of frameshift mutation than does the wild-type hAAG; the Y127I mutation accounts for the majority of the hAAG-Y127I/H136L-induced mutator phenotype. The hAAG-Y127I/H136L and hAAG-Y127I mutants increased the rate of spontaneous frameshifts by up to 120-fold in S. cerevisiae and also induced high rates of microsatellite instability (MSI) in human cells. hAAG and its mutants bind DNA containing one and two base-pair loops with significant affinity, thus shielding them from mismatch repair; the strength of such binding correlates with their ability to induce the mutator phenotype. This study provides important insights into the mechanism of hAAG-induced genomic instability.National Institutes of Health (U.S.) (Grant CA055042)National Institutes of Health (U.S.) (Grant CA115802)National Institutes of Health (U.S.) (Grant ES02109

Foreign investment in Scotland

A significant feature of the UK economy throughout the post-war period has been the growth in direct foreign investment in manufacturing industries. For the host nation the main benefits are employment creation, income generation and import reduction or export expansion. Scotland has been particularly successful in attracting the lion's inward investment for example in the period 1945- 1965 a total of 108,500 jobs were created by foreign firms setting up manufacturing units in the despite its size, obtained 46,221 (42.6%), whereas the second most SE England, gained only 16,926 (15.6%). The reasons for this success have been attributed primarily to a combination of the availability of labour in Scotland, the financial inducements offered by central government as part of regional policy and, the undoubted attraction of the environment, notably of course golf courses, for foreign businessmen. This brief paper explores the nature of Scotland's direct foreign investment and the reasons for its success

Tourism in Scotland

In 1978 13.2 million tourist and business travellers spent £523 million in Scotland, Foreign visitors, although only 8.5% of the total, contributed £158 million (ie 30.2%) of tourist expenditure. As such tourism is both an "invisible" export, since it is a means of earning foreign exchange, and a significant provider of jobs, many of which are created in the remoter rural areas. Despite its importance statistics relating specifically to tourism are not readily available from published sources. The "industry" actually combines the resources of a wide range of activities, most of which have economic and social links with other sectors of the economy independent from tourism. These include hotels and catering, transport and travel services as well as entertainment, sport and recreation facilities. Consequently the economic impact of tourism is generally assessed not in terms of employment and output but by more indirect measures such as numbers of visitors, or bednights spent in Scotland, as well as tourist expenditure and hotel occupancy data. This brief will examine the wider economic impact of Scotland's tourism industry and its future

The tax and price index

A feature of this year's Budget was the shift in emphasis from direct taxation to indirect taxation. The annual yield of income tax has been reduced by £4½ billion while that of direct taxes was increased by a similar amount. It must be acknowledged that the new tax and price index has a number of deficiencies. It is only applicable to a proportion of the population, namely those who pay tax and whose gross income is less than £10,000 per annum. It takes no account of the social wage, nor of changes in benefits, such as the recent restructuring of child allowance. It smoothes out tax payments over a full year even though, for administrative reasons, these may fluctuate widely from month to month. This brief paper explores some of these deficiencies in more detail and assess their impact on taxation

The Scottish economy [October 1979]

The previous two issues of this Commentary have both indicated that the Scottish economy has been performing poorly since the mid 1970's. This is true in both an absolute and a relative sense. Manufacturing production only increased by 1.2% between 1976 and 1978 and, after dropping below 1975 levels in the first quarter of 1979, is unlikely to show any substantial improvement for the year as a whole. In an international context the 1975-1978 performance can best be described as appalling. Over the same period industrial production in Eire grew by 28%, in Japan and the US by 23% and in West Germany and France by 15%. Inertia in developing new markets and lack of competitiveness in existing markets both contributed substantially to the virtual stagnation of Scottish output. Because the problems are so diverse, so too must be the solutions

The world economy [April 1979]

In the January issue of the Commentary is was pointed out that the mildly favourable prospects for world economic growth in 1979 were overshadowed by some political uncertainties, notably the prospect of disruptions to the supply of oil and the growth of protectionism. While the volume of world trade, as measured by the utilisation rates of dry cargo shipping, has continued to improve since the trough of June, 1978, there have been further less favourable political developments. This brief considers the impact of these developments and analyses the latest economic data

Spheres of Practice for the Co-design of Wearables

As expectations within the area of smart textiles increasingly become informed and driven by technological developments, the disciplinary boundaries and relationship between user and technological innovation will unavoidably transform. The authors venture that new paradigms of collaborative practice will inevitably develop between design and science, to more fully realize both the opportunities and contexts that wearable textiles offer. Drawing on previous work by the authors namely Molecular Imprinted Textiles (MIT - 2009/10), Future Textile Visions (FTV - 2010/11), Design Specks: Connecting People with Speckled Computing (2012/13), Second Skin (2013/14), and The S*** Word: Designing the Empathic Underwardrobe (2014), a model is proposed to more clearly understand and navigate between design, technology and application, and more importantly, between our cultural understanding of the user and the wearer. This paper reflects on a series of projects that inform a methodological approach: a process of asking questions; developing scenarios; exploring materials and making; generating concepts and building prototypes. Each project involved collaborations between design, academics, users and industry, and a form of co-design, where knowledge exchange was central, design was the intermediary, and the goal was to understand the drivers and the stakeholders. Simultaneously, this research sought to better understand and communicate the development of more empathic textile and fashion artifacts, and solutions. Co-design in this context is seen as a core approach to shifting the balance from technology as merely adjunct, or as a hook for marketers and users, to a more informed and harmonised position, where technology sits proximally and comfortably. The notion of interdisciplinary understanding, which tracks across domains of product, fashion and textiles, presents an approach where the application is still emerging. Through analysis of this progressive series of projects, the authors suggest that there is an opportunity to explore the inherent connectedness that textiles might offer for the integration and embedding of technology within material as a means to embrace these affordance opportunities. Central to this notion is the realisation of opportunities arising from dialogue and collaborative making (i.e. co-design), and for exploring the transformative notions of the user and the wearer. This paper led the authors to pose a set of questions that align to a four stage design process: Research, Define, Develop, Reflect, to frame findings and insights, and to outline the potential for future opportunities of working with technology to achieve the making and wearing of desirable materializations on the body

Pointing errors in non-metric virtual environments

There have been suggestions that human navigation may depend on representations that have no metric, Euclidean interpretation but that hypothesis remains contentious. An alternative is that observers build a consistent 3D representation of space. Using immersive virtual reality, we measured the ability of observers to point to targets in mazes that had zero, one or three ‘wormholes’ – regions where the maze changed in configuration (invisibly). In one model, we allowed the configuration of the maze to vary to best explain the pointing data; in a second model we also allowed the local reference frame to be rotated through 90, 180 or 270 degrees. The latter model outperformed the former in the wormhole conditions, inconsistent with a Euclidean cognitive map
