Interprofessional Collaboration in Reintegration After Prison for Prisoners with Substance Abuse Issues: A Scoping Review

Reintegration after prison for prisoners with interlinked welfare needs has been one of the most challenging issues for decades in the criminal justice system. The WHO and the UN highlight the demand for well-functioning collaboration between professionals and welfare agencies handling these challenges. However, interprofessional collaboration has been an underdeveloped field of research and theory, especially concerning prisoners with substance abuse issues. The present study undertakes a scoping review of research on interprofessional collaboration in reintegration after prison for prisoners with substance abuse issues, particularly identifying factors that influence collaboration. Nineteen included studies from the USA, the U.K., Australia, and Norway show that relational and structural factors influence collaboration and that innovative projects are perceived as improving collaboration. A tentative conceptual model of factors that influence collaboration is presented and may serve as a basis for reflection and further development of a theoretical framework within the field of research

Remote sensing of avalanches in northern Norway using Synthetic Aperture Radar

We present results from using synthetic aperture radar data (SAR) to analyse three avalanches in the county of Troms in northern Norway during the late snow season 2013. During a persistent polar low pressure activity at the end of March and the beginning of April 2013, inducing high precipitation rates in combination with high wind speeds, an extensive avalanche cycle took place in that area. Several avalanches released naturally causing fatalities, road closures and community evacuations. The main goal of our study was to investigate whether high resolution SAR could be used for detecting avalanche debris in the run-out zones. For validation purposes we used, among others, a high resolution camera operated on an Unmanned Airborne Vehicle (UAV) to acquire very accurate ortho-photos of the avalanches. The UAV-maps were of unprecedented resolution (~5 cm). The result of the analysis of the high resolution Radarsat-2 image showed that avalanches could be identified visually due to the high contrast between low radar backscatter from unperturbed snow and high backscatter (caused by increased surface roughness/snow mass) of the avalanche debris in the avalanche run-out zones. In order to assess the accuracy, the avalanche delineations were compared with results from UAV photos and photographs taken during helicopter reconnaissance flights right after the events. In two of three cases, a good correspondence was found between SAR delineated avalanches and outlines derived from optical data

InSAR Svalbard – User requirements, technical considerations, and product development plan

The InSAR Svalbard development project (2023–2025) is a partnership between the Geological Survey of Norway (NGU) and NORCE Norwegian Research Centre AS, with funding from the Norwegian Space Agency (Post 74, contract number: 74CO2301). The project aims to start the development of a Ground Motion Service (GMS) in Svalbard, providing spaceborne Synthetic Aperture Radar Interferometry (InSAR) ground displacement maps and time series tailored to Arctic conditions. This report presents the findings from the project's first year, including the outcomes of a user workshop and a user survey conducted in 2023. The study's main goal was to identify the user requirements for an InSAR Svalbard GMS, and to highlight past InSAR research and known for processing limitations. The report also presents a product development plan that considers both user needs and technical considerations.publishedVersio

The Extended Timing Annotation Dataset for Sentinel-1 - Product Description and First Evaluation Results

This article introduces the extended timing annotation dataset (ETAD) product for Sentinel-1 (S-1) which was developed in a joint effort of German Aerospace Center (DLR) and European Space Agency (ESA). It allows to correct range and azimuth timing of S-1 images for geophysical effects and for inaccuracies in synthetic aperture radar (SAR) image focusing. In combination with the precise orbit solution, these effects determine the absolute geolocation accuracy of S-1 SAR images and the relative collocation accuracy of repeat pass image stacks. ETAD contains the gridded timing corrections for the tropospheric and ionospheric path delays, the tidal-based surface displacements, and the SAR processing effects, all of which are computed for each data taken using standard models from geodesy and auxiliary atmospheric data. The ETAD product helps S-1 users to significantly improve the geolocation accuracy of the S-1 SAR products to better than 0.2 m and offers a potential solution for correcting large-scale interferometric phase variations. The product layout and product generation are described schematically. This article also reports first the results for different SAR techniques: first, the improvement in geolocation accuracy down to a few centimeters by verification of accurately surveyed corner reflector positions in the range–azimuth plane; second, the well-established offset-tracking technique, which is used for systematic ice velocity monitoring of ice sheets and glaciers, where ETAD can reduce velocity biases down to subcentimetric values; and third, the correction of atmospheric phase contributions in wide-area interferograms used for national and European ground motion services. These early results proof the added value of the ETAD corrections and that the product design is well-suited to be integrated into the processing flows of established SAR applications such as absolute ranging of targets, speckle/feature tracking, and interferometry

Evaluation of ESA's Extended Timing Annotation Dataset (ETAD) for Sentinel-1 - First Results for Ice Velocity Monitoring and InSAR Applications in Greenland, Iceland and Norway

SAR images benefit from excellent geometric accuracy due to accurate time measurements in range and precise orbit determination in azimuth. Moreover, the interferometric phase of each single pixel can be exploited to achieve differential range measurements for the reconstruction of topography and the observation of earth surface deformation and surface motions. But these measurements are influenced by the spatial and temporal variability of the atmospheric conditions, by Earth dynamics, and by SAR processor approximations, which may lead to overall displacements shifts of up to several meters. These effects become visible in various SAR applications including the retrieval of ice velocity applying offset tracking and various InSAR applications, which might require several post-processing steps and external information for correction. In this paper we present the Extended Timing Annotation Dataset (ETAD) for Sentinel-1 recently developed in a joint effort by ESA and DLR based on research results and processor prototypes available at DLR

The 2014–2015 eruption of Fogo volcano: Geodetic modeling of Sentinel-1 TOPS interferometry

After 20 years of quiescence, Fogo volcano erupted in November 2014. The eruption produced fast-moving lava flows that traveled for several kilometers and destroyed two villages. This event represents the first episode of significant surface deformation imaged by the new European Space Agency's Sentinel-1 satellite in its standard acquisition mode, Terrain Observation by Progressive Scans (TOPS), which differs from that of previous synthetic aperture radar (SAR) missions. We perform a Bayesian inversion of Sentinel-1 TOPS SAR interferograms spanning the eruption and accurately account for variations in the TOPS line-of-sight vector when modeling displacements. Our results show that magma ascended beneath the Pico do Fogo cone and then moved laterally toward its southwestern flank, where the eruptive fissure opened. This study provides important insights into the inner workings of Fogo volcano and shows the potential of Sentinel-1 TOPS interferometry for geophysical (e.g., volcano monitoring) applications
