Eliciting data from participants using visual mapping as a collection technique

This article uses the project evaluation of the School-Aged Therapy Service for children with disabilities in Western Australia as an example of alternative ways to gather qualitative data from participants. The purpose of the evaluation was to pave the way for considerable and quick developmental operational change in order to stem the complaints from users of the service and to provide more effective service delivery. With this in mind the research team determined it was necessary to ‘map’ the current model of operation as there was inconsistency from the staff as to their understanding, and their ideal model of operation before presenting a new model to management. To facilitate the change process the researchers conducted a final focus group two months after the formal evaluation to map the staff’s perceptions of how the proposed new model would work and the challenges the changes would produce. This article presents ‘visual maps’ that have been drawn by the staff to demonstrate that this technique provides rich, raw, timely, collaborative artefacts that are invaluable for organizations encouraging change

A user's guide for V174, a program using a finite difference method to analyze transonic flow over oscillating wings

The design and usage of a pilot program using a finite difference method for calculating the pressure distributions over harmonically oscillating wings in transonic flow are discussed. The procedure used is based on separating the velocity potential into steady and unsteady parts and linearizing the resulting unsteady differential equation for small disturbances. The steady velocity potential which must be obtained from some other program, is required for input. The unsteady differential equation is linear, complex in form with spatially varying coefficients. Because sinusoidal motion is assumed, time is not a variable. The numerical solution is obtained through a finite difference formulation and a line relaxation solution method

The state of EU sports law: lessons from UEFA’s ‘Financial Fair Play’ regulations

The EU’s sporting competence derives from the legal norm, established by the European Court of Justice, that requires that ‘sporting rules’ of sports governing bodies which have an economic impact and which breach the fundamental freedoms or competition law can only be justified if shown to be a proportionate response to an inherent need in the sport. However, the certainty of this norm is undermined by the EU’s subsequent Treaty competence for sport, a political compromise, which is ambiguous, and which in due course generated the European Commission’s sports policy, with its emphasis on governance and social dialogue. Consequently, EU sports law has evolved into ‘soft law’ which is far from coherent. This is demonstrated in the tolerance shown for certain of UEFA’s ‘sporting rules’, notably its Financial Fair Play Regulations, which restrict competition and lack proportionality yet have not attracted sanction from the European Commission (a sports law policy which could be characterised as not even constituting soft law but delegalisation)

Manipulating ultracold atoms with a reconfigurable nanomagnetic system of domain walls

The divide between the realms of atomic-scale quantum particles and lithographically-defined nanostructures is rapidly being bridged. Hybrid quantum systems comprising ultracold gas-phase atoms and substrate-bound devices already offer exciting prospects for quantum sensors, quantum information and quantum control. Ideally, such devices should be scalable, versatile and support quantum interactions with long coherence times. Fulfilling these criteria is extremely challenging as it demands a stable and tractable interface between two disparate regimes. Here we demonstrate an architecture for atomic control based on domain walls (DWs) in planar magnetic nanowires that provides a tunable atomic interaction, manifested experimentally as the reflection of ultracold atoms from a nanowire array. We exploit the magnetic reconfigurability of the nanowires to quickly and remotely tune the interaction with high reliability. This proof-of-principle study shows the practicability of more elaborate atom chips based on magnetic nanowires being used to perform atom optics on the nanometre scale.Comment: 4 pages, 4 figure

Development of the X-ray camera for the OGRE sub-orbital rocket

Current theories regarding the matter composition of the universe suggest that half of the expected baryonic matter is missing. One region this could be residing in is intergalactic filaments which absorb strongly in the X-ray regime. Present space based technology is limited when it comes to imaging at these wavelengths and so new techniques are required. The Off-Plane Grating Rocket Experiment (OGRE) aims to produce the highest resolution spectrum of the binary star system Capella, a well-known X-ray source, in the soft X-ray range (0.2keV to 2keV). This will be achieved using a specialised payload combining three low technology readiness level components placed on-board a sub-orbital rocket. These three components consist of an array of large format off-plane X-ray diffraction gratings, a Wolter Type 1 mirror made using single crystal silicon, and the use of EM-CCDs to capture soft X-rays. Each of these components have been previously reviewed with OGRE being the first project to utilise them in a space observation mission. This paper focuses on the EM-CCDs (CCD207-40 by e2v) that will be used and their optimisation with a camera purposely designed for OGRE. Electron Multiplying gain curves were produced for the back-illuminated devices at -80 degrees Celsius. Further tests which will need to be carried out are discussed and the impact of the OGRE mission on future projects mentioned

Popular attitudes to memory, the body, and social identity : the rise of external commemoration in Britain, Ireland, and New England

A comparative analysis of samples of external memorials from burial grounds in Britain, Ireland and New England reveals a widespread pattern of change in monument style and content, and exponential growth in the number of permanent memorials from the 18th century onwards. Although manifested in regionally distinctive styles on which most academic attention has so far been directed, the expansion reflects global changes in social relationships and concepts of memory and the body. An archaeological perspective reveals the importance of external memorials in articulating these changing attitudes in a world of increasing material consumption
