Design recommendations for the creation of icons for the elderly

During employment of icons in order to represent system functions, specific user requirements from elderly people have not been scientifically gathered and thus will merely be considered during the process of system design. The survey, with explicit consideration of technology acceptance and experience of 120 elderly probands, looked into the comprehension of four different classes of non-animated graphical representations. It was shown that among elderly, the use of photos compared to pictograms or clip art leads to a significantly higher recognition rate. The mapping of actions rather than objects leads to a further reduction of the error probability and is thus, especially in the context of telemedicine, preferable for the target group.     

Adaptive information design for outdoor augmented reality

Augmented Reality focuses on the enrichment of the user's natural field of view by consistent integration of text, symbols and interactive three-dimensional objects in real time. Placing virtual objects directly into the user's view in a natural context empowers highly dynamic applications. On the other hand, this necessitates deliberate choice of information design and density, in particular for deployment in hazardous environments like military combat scenarios. As the amount of information needed is not foreseeable and strongly depends on the individual mission, an appropriate system must offer adequate adaptation capabilities. The paper presents a prototypical, vehicle-mountable Augmented Reality vision system, designed for enhancing situation awareness in stressful urban warfare scenarios. Tracking, as one of the most crucial challenges for outdoor Augmented Reality, is accomplished by means of a Differential-GPS approach while the type of display to attach can be modified, ranging from ocular displays to standard LCD mini-screens. The overall concept also includes envisioning of own troops (blue forces), for which a multi-sensor tracking approach has been chosen. As a main feature, the system allows switching between different information categories, focusing on friendly, hostile, unidentified or neutral data. Results of an empirical study on the superiority of an in-view navigation cue approach conclude the paper.     

How to reduce workload--augmented reality to ease the work of air traffic controllers

In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction.     

Waged Slavery – Incentivizing Unfree Labour at Cape Coast Castle in the Eighteenth Century

This article studies the payment of wages to castle slaves at Cape Coast Castle (in current-day Ghana) in the eighteenth century. A quantitative estimate shows that the wages paid to these slaves were considerably higher than subsistence costs. A large sample of wage payments is also used in order to analyse statistically the existing wage differentials among the slaves. The results indicate that a complex wage structure had been developed in order to incentivize the slaves to work and to foster loyalty towards the slaveholder.     

Making Sense of After‐School Care Dilemmas in Mothers' Stories of After‐School Care in Finland and Sweden

The study focuses on dilemmas in storied experiences of everyday after‐school care arrangements among Swedish and Finnish mothers. Finland and Sweden, which share a history of strong labour market attachment among women, arrange institutional after‐school care in similar ways. The data consist of interviews with three Swedish and six Finnish mothers. A positioning analysis of four stories shows how decisions related to children's after‐school hours were allocated among different actors. Two reoccurring dilemmas, Competent‐dependent child stories and Unburdened‐deficient mother stories, emerged from the data analysis as related to prevailing moral discourses on childhood and motherhood.     

Distress or disability? Could a theoretical framework drawn from disability studies be a way forward when trying to understand experiences of oppression on the grounds of mental distress?

This article explores whether it is possible to use a theoretical framework drawn from disability studies to understand experiences of social oppression on the grounds of mental distress. Thomas’ extended social relational theoretisation of disablism was used in a PhD project concerned with experiences of mental distress. The tentative conclusion was that Thomas’ conceptualisation of disablism and impairment could offer a way of improving understanding of mental distress and oppression on the grounds of mental distress. However, Thomas and Reeve’s theorisation of the different forms of disablism was not readily transferred to the field of mental distress. Thus, tentative definitions of the different forms of disablism in relation to the field of mental distress were created. Perceived impairment type and disablism appear to be interconnected, and one has to acknowledge what kind of perceived impairment type one is focusing on when theorising disability and the different types of disablism.     

Collective empowerment: A comparative study of community work in Mumbai and Stockholm

Mumbai and Stockholm are worlds apart in terms of public services, infrastructures and standard of living. However, both cities have known common problems of social exclusion and marginalisation related to neo‐liberal globalisation. Social workers are facing similar challenges regarding collective empowerment as a strategy for community work. This comparative study explored how collective empowerment is undertaken by community workers. The research participants were 13 informants from community‐work organisations in the two settings. Semi‐structured interviews were used and were analysed with the help of Atlas‐ti 6.2 (ATLAS.ti Scientific Software Development GmbH D‐10623 Berlin Germany). Social work in Mumbai is in a context of extreme poverty and mainly within the informal sector, whereas in Stockholm most social work is done in relation to a public welfare model. In Stockholm, interventions are aimed towards strengthening social networks, without direct aim at social change. In Mumbai, community workers organise people for collective empowerment to strengthen marginalised groups and achieve social change.
