Measurement precision of body composition variables in elite wheelchair athletes,using dual-energy X-ray absorptiometry

The purpose of this study was to assess the reproducibility of body composition measurements by dual-energy X-ray absorptiometry (DXA) in 12 elite male wheelchair basketball players (age 31 ± 7 years, BMI 21 ± 2 kg/m² and onset of disability 25 ± 9 years). Two whole body scans were performed on each participant in the supine position on the same day, using Lunar Prodigy Advance DXA (GE Lunar, Madison, WI, USA). Participants dismounted from the scanning table and were repositioned in-between the first and second scan. Whole body coefficient of variation (CV) values for bone mineral content (BMC), fat mass (FM) and soft tissue lean mass (LTM) were all <2.0%. With the exclusion of arm FM (CV = 7.8%), CV values ranged from 0.1 to 3.7% for all total body and segmental measurements of BMC, FM and LTM. The least significant change that can be attributed to the effect of treatment intervention in an individual is 1.0 kg, 1.1 kg, 0.12 kg for FM, LTM, and BMC, respectively. This information can be used to determine meaningful changes in body composition when assessed using the same methods longitudinally. Whilst there may be challenges in the correct positioning of an individual with disability that can introduce greater measurement error, DXA is a highly reproducible technique in the estimation of total and regional body composition of elite wheelchair basketball athletes.     

Supporting new school leaders: findings from a university‐based leadership coaching program for new administrators

Administrators need intense support in their early years in their jobs to master the demands of the position and to emerge as effective leaders for their schools. This article reports on a leadership coaching program offered by a university to support graduates as they transition to new school leadership roles. First year research results of the Program for New Principals indicate that all of the program participants felt that the coaching program was a positive addition to the induction experience for new administrators. New principals viewed coaching positively and emphasized that it is both a valuable and unique form of professional development. Both coaches and new principals cited personalized support as one of the coaching model's most significant assets. The results should inform the development of a model of leadership coaching for new administrators.     

Cell chip array for microfluidic proteomics enabling rapid in situ assessment of intracellular protein phosphorylation

We discuss the ability to perform fluorescent immunocytochemistry, following cell fixation, using a microfluidic array of primary, nonadherent, single CD34+ stem cells. The technique requires small cell samples and proceeds with no cell loss, making it well-suited to monitoring these rare patient-derived cells. The chip allows us to correlate live cell dynamics across arrays of individual cells with post-translational modifications of intracellular proteins, following their exposure to drug treatments. Results also show that due to the microfluidic environment, the time scale of cell fixation was significantly reduced compared to conventional methods, leading to greater confidence in the status of the protein modifications studied.     

Inclusive pedagogy in action: getting it right for every child

A key assumption underpinning formative assessment strategies is that individual pupils must be fully involved in the process. While such engagement and attention on the individual is important, studies suggest that teachers do not always readily engage with formative assessment as a reciprocal process which involves pupils. Additionally, a focus on individual differences between pupils can be problematic if the work that is set for some is differentiated to such an extent that they are not able to participate in classroom activities with others. Inclusive pedagogy is an approach to teaching and learning that attends to individual differences between pupils but avoids the marginalisation that can occur when pedagogical responses are designed only with individual needs in mind. Using participant observation and video footage from three classrooms that captured ‘learning moments’ identified by teachers and pupils, this study documents how the professional craft knowledge of teachers develops as they learn to use what their pupils have to say about learning in the context of whole class teaching. By concentrating on the findings from one site, this paper shows how teachers can use what they learn from listening to pupils’ self-assessments of their learning in ways that meet the standard of inclusive pedagogy.     

Causes of tension in post-observation feedback in pre-service teacher training: An alternative view

A central component in pre-service teacher training is teaching practice and feedback. In some cases, feedback results in disquiet and tension (Brandt, 2008). Many researchers attribute this tension to the incompatibility of the assessment and development roles that the trainer must perform. The research reported on here, however, suggests that tension may also be rooted in a difference in expectation amongst trainers and trainees about the purpose and performance of feedback. This can result in trainees not playing by the rules of the game (Roberts & Sarangi, 2001) either because they do not understand them or because they wish to challenge them.     

“They Think They Know What’s Best for Me”: An Interpretative Phenomenological Analysis of the Experience of Inclusion and Support in High School for Vision-impaired Students with Albinism

The challenges of social inclusion and access to the curriculum facing students with visual impairment in schools are well documented. The refreshed UK Vision Strategy (2013 UK Vision Strategy. (2013). Outcome 3. Retrieved from http://www.vision2020uk.org.uk/UKVisionstrategy/page.asp?section=289&sectionTitle=Outcome+3 [Google Scholar]) seeks to improve education for students with vision impairment. In order to do this, it is important to understand how students with visual impairment experience education. This study used interpretative phenomenological analysis to examine and understand the way in which two vision-impaired students with albinism experienced inclusion and support in high school. The students, aged 16 and 15, had approximately 10% functional vision, stable from birth and had a record of additional support needs at their respective schools. They were interviewed using a simple schedule of open questions to explore their perceptions of inclusion and of using low-vision aids in school. The two main themes that emerged from the interviews were experiencing low vision in school and experiencing additional support in school. A negative cycle of inclusion was identified based on the students’ internalised feelings of difference. Discrepancy was identified between the low-vision aid priorities identified by experts and those identified by students. Recommendations are made to address these issues.
