The shallow magma system beneath Sierra Negra was imaged using attenuation tomographic methods. The t∗ spectral decay method for P wave phases was used to highlight regions of high Qp−1 which suggest the presence of magma melt. High‐ Qp−1 anomalies ranging from 0.005 to 0.04 are concentrated below the caldera from 0.5 to 10.5 km depths. Attenuation is sensitive to temperature and fluid presence; thus, this high attenuation is interpreted as possible zones of magma accumulation. An imaged shallow body is consistent with geodetic studies on caldera deformation that modeled a magma sill or flattopped diapir of unknown thickness at ∼1 km depth below sea level.

The Community Occupational Therapy Service (Equipment and Adaptations) at Worcestershire Health and Care National Health Service Trust, Redditch and Bromsgrove Locality identified the need to find an outcome measure that would determine its effectiveness. The Canadian Occupational Performance Measure was chosen as a client-centred, reliable, and validated outcome measure that was integrated within existing paperwork. The process followed is outlined in this practice analysis. The service completed 1,869 Canadian Occupational Performance Measure scores, which showed a statistically significant increase in client ratings of performance and satisfaction in 90% of clients, illustrating the effectiveness of the service. The aim of this practice analysis is to explain the process that this service followed to integrate the Canadian Occupational Performance Measure into practice and, thus, share the benefit of using it as an outcome measure with colleagues who work in a similar setting. The authors highlight the importance of continuing with the Canadian Occupational Performance Measure and look to develop its use further.
