Frequently an unquestioned belief is held in British schools in the value of "normalized" ability in physical education (PE). Consequently inclusion of disabled students can be problematic. Negative perceptions of disability are rarely challenged. This study investigated the embodied experiences of 49 non-disabled secondary school pupils during a programme designed to introduce disability sport to non-disabled school children entitled "The Wheelchair Sports Project". Funded by a County Sports Partnership, Wheelchair Basketball sessions were delivered by trained coaches during PE for a 12-week period. Forty-nine pupils aged between 10 and 12 years took part in the study. Non-participant observations were completed during the programme, and semi-structured group interviews were completed with 24 participants pre- and post-project. Bourdieu's theoretical framework guided data analysis. The impact of the project on pupils' perceptions of physical disability was investigated. Prior to the project, pupils emphasized the "otherness" of disabled bodies and described disability sport as inferior and not "real". Observations highlighted how pupils experienced physical challenges adapting to wheelchair basketball. Pupils struggled to control wheelchairs and frequently diverged from acceptable behaviour by using their lower limbs to "cheat". Post-programme group interviews demonstrated that, due to their own embodied experiences, pupils began to question their perceptions of the potential ability of participants with physical impairments. Pupils described high physical demands of wheelchair basketball and began to focus upon similarities between themselves and physically disabled individuals. However, participants made no reference to impairments other than physical disability, emphasizing the specificity of the effects of pupils' embodied experiences on their embodied habitus, which, although difficult to assess over the long term, appeared to have an impact on self-perceptions over the short term.

The singlet state of nuclear spin-1/2 pairs is protected against many common relaxation mechanisms. Singlet order, which is defined as the population difference between the nuclear singlet and triplet states, usually decays more slowly than the nuclear magnetization. Nevertheless, some decay mechanisms for nuclear singlet order persist. One such mechanism is called scalar relaxation of the second kind (SR2K) and involves the relaxation of additional nuclei ("third spins") which have scalar couplings to the spin-1/2 pair. This mechanism requires a difference between the couplings of at least one third spin with the two members of the spin-1/2 pair, and depends on the longitudinal relaxation time of the third spin. The SR2K mechanism of nuclear singlet relaxation has previously been examined in the case where the relaxation rate of the additional spins is on the time scale of the nuclear Larmor frequency. In this paper, we consider a different regime, in which the longitudinal relaxation of the third spins is on a similar time scale to the J-coupling between the members of the spin pair. This regime is often encountered when the spin-1/2 pair has scalar couplings to nearby deuterium nuclei. We show that the SR2K mechanism may be suppressed in this regime by applying a radiofrequency field which is resonant either with the members of the spin pair, or with the third spins. These phenomena are analyzed theoretically and by numerical simulations, and demonstrated experimentally on a diester of [13C2, 2H2]-labeled fumarate in solution. [ABSTRACT FROM AUTHOR]
