To assess the value of satellite photographs in resource evaluation on a national scale

The author has identified the following significant results. The limit of resolution on ERTS imagery is normally acknowledged to be about 60 miles although very long features such as roads and railways which are often less than 10 miles long are easily detectable. An example is the north-south road and railway from Lobatse to Francistown. Vegetation growth from winter to summer is readily monitored on false color imagery. The limits of government ranches and special farming areas can be quite accurately ascertained from ERTS imagery. Another aspect to which ERTS imagery lends itself is the location and demarcation of bush fires, many of which were seen on the first imagery which was acquired at the end of the cold, dry season. As a whole, MSS 7 offers maximum reflectance contrast among black and white imagery and is the wavelength used most for interpretation

Modelling treatment, age- and gender-specific recovery in acute injury studies

Background: Acute injury studies often measure physical ability repeatedly over time through scores that have a finite range. This can result in a faster score change at the beginning of the study than towards the end, motivating the investigation of the rate of change. Additionally, the bounds of the score and their dependence on covariates are often of interest. Methods: We argue that transforming bounded data is not satisfactory in some settings. Motivated by the Collaborative Ankle Support Trial (CAST), which investigated different methods of immobilisation for severe ankle sprains, we developed a model under the assumption that the recovery rate at a specific time is proportional to the current score and the remaining score. This model enables a direct interpretation of the covariate effects. We have re-analyzed the CAST data using these improved methods, and explored novel relationships between age, gender and recovery rate. Results: We confirm that using below knee cast is advantageous compared with a tubular bandage in relation with the recovery rate. An age and gender effect on the recovery rate and the maximum achievable score is demonstrated, with older female patients recovering less fast (age-effect: -0.21, 95% confidence interval (CI) [-0.28,- 0.14]; gender effect: -0.06, CI [-0.12,-0.004]) and achieving a lower maximum score (age-effect: -8.07, CI [-11.68,-4.01]; gender-effect: -5.34, CI [-8.18, -2.50]) than younger male patients. Conclusions: Our model is able to accurately model repeated measurements on the original scale, while accounting for the bounded nature of a score. We demonstrate that recovery in acute injury trials can differ substantially by age and gender. Older female patients are less likely to recover well from a sprain

'Lessons learned' from introducing universal strategies designed to support the motor and functional skills of Reception and Year 1 children in a sample of primary schools in South East England

This article describes an evaluation of universal resources designed to support motor development in Reception and Year 1 children. Four schools (Year R - Year 6) in the South East of England, three with high numbers of disadvantaged children participated. Senior leadership influenced take up of the initiative. Health and well-being practitioners and occupational therapy students contributed to ‘roll out’ of the resources with support provided by the authors over 12 weeks. Interview and focus group data from participating staff were gathered alongside examples of schoolwork from pupils. School staff needed access to support when incorporating universal strategies. The initiative contributed to schools working towards Healthy Schools targets. At the end of 12 weeks improvements in children’s sitting position, handwriting and lunch time skills were noted, warranting further exploration of this approach to address the needs of children with poor motor skills at school entry

Writing readiness and children with Down Syndrome in an Irish context

There is a dearth of studies investigating writing readiness in children with Down Syndrome (DS) and limited information on appropriate interventions. This article reports on a study conducted in the Republic of Ireland. An uncontrolled pretest-posttest design was implemented using writing readiness measures specifically adapted/developed from the literature to collect data on the writing readiness skills of 28 school-aged children with DS attending mainstream schools in the Republic of Ireland. Teacher/parent perspectives were also gathered during focus groups. The children presented with complex needs in relation to posture, pencil grasp, copying basic shapes, name/letter copying. Teacher and parent reports highlighted the need for collaborative intervention with occupational therapy. Findings from the study supports the need for targeted early collaborative syndrome-specific intervention to support the development of writing readiness in children with DS as an important part of school readiness. Intervention should include adopting a broader emergent literacy approach, teacher education regarding writing readiness and parental involvement in intervention

Exploring the participation of children with Down Syndrome in Handwriting Without Tears®

Background Children with Down Syndrome typically experience difficulties with attention to task and lack motivation when learning to write. This article provides an evaluation of the HWT® method applied as an intervention to promote handwriting amongst children with Down Syndrome attending mainstream school in The Republic of Ireland. Methods In the absence of standardised measures, a purpose-designed group task participation scale and pre- and post-intervention teacher/parent questionnaire were developed by the first author and used to investigate the participation of 40 children with Down Syndrome in HWT® activities. Results Positive changes in participation in HWT® activities were recorded in group data and in teacher/parent report. Conclusions Hands-on multisensory learning approaches such as HWT® may encourage children with Down Syndrome to participate in activities that promote handwriting skills. Further research and the development of robust measures to evaluate handwriting intervention for this population of children is require

Identifying studies for systematic reviews - An example from medical imaging

Objectives: To determine if published figures on the proportion of articles included in systematic reviews and identified in electronic databases are applicable to an example from medical imaging. Methods: A systematic review was performed. Additionally, sensitivity and precision of a MEDLINE search were compared with values from three published searches, each customized for a specific field. Results: All articles included in the systematic review were in electronic databases. The MEDLINE search had low precision compared with searches in other fields. Conclusions: in a specific area of medical imaging, electronic databases, including MEDLINE, are reliable sources of articles
