Traumatic brain injury (TBI) is the biggest cause of death and disability in children and young people. TBI compromises important neurological functions for self-regulation and social behaviour and increases risk of behavioural disorder and psychiatric morbidity. Crime in young people is a major social issue. So-called early starters often continue for a lifetime. A substantial majority of young offenders are reconvicted soon after release. Multiple factors play a role in crime. We show how TBI is a risk factor for earlier, more violent, offending. TBI is linked to poor engagement in treatment, in-custody infractions, and reconviction. Schemes to assess and manage TBI are under development. These might improve engagement of offenders in forensic psychotherapeutic rehabilitation and reduce crime.

Research demonstrates the important role of refugees and asylum seekers' social networks in providing both the practical and emotional support necessary to mitigate social exclusion and promote integration within receiving societies. Based on research conducted by the National Evaluation of the Children's Fund, we highlight the barriers to network building for refugee and asylum seeking children and families, and the ways in which Children's Fund strategies and practices are tackling these. Using the ‘Indicators of Integration Framework’ developed by Ager and Strang (2004), we describe the activity of Children's Fund services in relation to the concepts social bonds, social links and social bridges. Such attempts to reduce social exclusion are seen to have limited effectiveness when framed by a government policy context favouring the development of social bridges at the expense of social links and bonds.

Reported prevalence rates of brain injury among incarcerated youth range from 16.5% to 72.1%, with a rate of 100% reported among a sample of young people sentenced to death. This suggests considerable levels of need among incarcerated young people. Where control groups or directly comparable studies within the general population exist, there is strong and consistent evidence of a prevalence of TBI among incarcerated youth that is substantially greater than that in the general population. This disparity is seemingly more pronounced as the severity of the injury increases.

content validity of the instrument were established and an exploratory factor analysis used to guide restructuring of the tool. Internal consistency/reliability was calculated using Cronbach's a . RESULTSUsing the scale showed that men with prostate cancer placed considerable importance on a broad range of information needs, most of which had been inadequately met. Age had a significant influence on the overall importance attributed to information, with younger patients having more need for information. The construct and content validity of the instrument were established. The factor analysis revealed four discrete factors which together explained > 68% of the variance, termed 'basics of prostate cancer care', 'disease management', 'physical well-being' and 'self-help' . Internal consistency/reliability was satisfactory ( a = 0.91). CONCLUSIONSThe basis of a tool capable of ascertaining the information needs of patients with prostate cancer was developed; it may offer clinicians a valid means of ascertaining information preferences and hence potentially enhance the quality of service provided. Further research is now required to refine the tool and test the effect of its longitudinal use in clinical practice on patient satisfaction and outcome. KEYWORDSprostate cancer, information needs, assessment scale OBJECTIVETo design, from first principles, a valid and reliable scale for assessing the importance of specific items of information needed by patients with prostate cancer that would be straightforward to use in clinical settings, as despite its prevalence, there is little research focusing specifically on the information needs associated with prostate cancer. PATIENTS AND METHODSSeveral stages of consultation and modification were used to inform the development of a scale which was then piloted on 96 patients with prostate cancer. Respondents were asked to rate the importance they placed on a range of prostate cancer-related topics of information, and the extent to which they felt these information needs had been met. The construct and

Humans are able to form a complex mental model of the environment they move in. This mental model captures geometric and semantic aspects of the scene, describes the environment at multiple levels of abstractions (e.g., objects, rooms, buildings), includes static and dynamic entities and their relations (e.g., a person is in a room at a given time). In contrast, current robots' internal representations still provide a partial and fragmented understanding of the environment, either in the form of a sparse or dense set of geometric primitives (e.g., points, lines, planes, voxels), or as a collection of objects. This paper attempts to reduce the gap between robot and human perception by introducing a novel representation, a 3D Dynamic Scene Graph (DSG), that seamlessly captures metric and semantic aspects of a dynamic environment. A DSG is a layered graph where nodes represent spatial concepts at different levels of abstraction, and edges represent spatio-temporal relations among nodes. Our second contribution is Kimera, the first fully automatic method to build a DSG from visual-inertial data. Kimera includes state-of-the-art techniques for visual-inertial SLAM, metric-semantic 3D reconstruction, object localization, human pose and shape estimation, and scene parsing. Our third contribution is a comprehensive evaluation of Kimera in real-life datasets and photo-realistic simulations, including a newly released dataset, uHumans2, which simulates a collection of crowded indoor and outdoor scenes. Our evaluation shows that Kimera achieves state-of-the-art performance in visual-inertial SLAM, estimates an accurate 3D metric-semantic mesh model in real-time, and builds a DSG of a complex indoor environment with tens of objects and humans in minutes. Our final contribution is to showcase how to use a DSG for real-time hierarchical semantic path-planning. The core modules in Kimera have been released open source.

Adolescents detained within the criminal justice system are affected by complex health problems, health-risk behaviours, and high rates of premature death. We did a global synthesis of the evidence regarding the health of this population. We

Earlier identification of language difficulties requires routine assessment of young people at risk of engagement in offending behavior. Where language difficulties are identified, holistic assessments of needs should be undertaken. There is a need for speech and language therapy provision within youth justice services, as well as in other services accessed by young people at risk of engagement in offending.
