Sounding grief: the Severn Estuary as an emotional soundscape
This paper explores sound infused creative responses to grief and related emotions of loss and landscape in the context of the tidal Severn Estuary (UK) and its particular sonic qualities. We draw principally on the practice of artist Louisa Fairclough, linking to wider discussions of emotion, sound and the body, in shared autotopological explorations of self and family in landscape. Like other estuaries, the Severn Estuary is a deeply rich (in socio-ecological terms) landscape which includes the tidal liminalities of the lower reaches of the Severn river, the mid estuary, and the lower areas which merge into open sea. The whole estuary, in geomorphological, ecological, and related social terms, is particularly dynamic as it has the second highest tidal range in the world. This means that vast volumes of brackish water wash up and down the estuary in a series of rhythmic cycles which play across and between day, month and season, mixing physical spaces and processes (e.g. land-sea; salt-fresh water). This ceaseless ebb and flow brings marked spatial, visual and aural richness to the estuary and places along its shores. This includes the Severn bore which, when at maximum height, is a powerful tidal wave washing up the upper estuary and tidal river with a loud sonic richness. Owain Jones (geographer) has previously written on this landscape and its memorial emotional qualities in relation to his family history and challenged geographical self. Louisa Fairclough (artist) has re-turned to it as performative art practice, to sleep by the River Severn, and produces a series of works consisting of field recordings, drawings and a series of installations of expanded films. These use river sounds and vocal recordings to interact with the tidal landscape and its margins in creative expressions of grief. This paper sets out these works, their background, shared responses to the estuary, and explores in particular the sonic registers of the landscape which, for us, listen, and speak to, loss and trauma
Physical activity and play behaviours in children and young people with intellectual disabilities: A cross-sectional observational study
The benefits of physical activity and active play for children and young people are well established. However, there is a lack of physical activity research involving children and young people with intellectual disabilities. This study investigated habitual physical activity and recess play behaviour in 70 5- to 15-year-old participants with intellectual disabilities using objective methods (accelerometers) and systematic observation techniques. Results showed that few children were active enough to benefit their physical health (23% of the cohort). No differences in habitual physical activity, sedentary behaviour, or recess play behaviours were observed between boys and girls. Participants spent most of their recess time alone or playing in small groups, with no participants engaging in large group play. Older participants spent more recess time playing in small groups rather than playing alone and participants with Autistic Spectrum Disorder spent more time engaged in active pursuits and less time standing than non-Autism Spectrum Disorder participants. Positive correlations were observed between time spent alone and physical activity. These findings contrast with those typically observed in a mainstream school setting. In conclusion, interventions designed from formative research are needed to promote physical activity within this population. Implications for school psychologists are discussed
A simple layout optimization formulation for load-carrying tensegrity structures
Traditional tensegrity structures comprise isolated compression members lying inside a continuous network of tension members. In this contribution, a simple numerical layout optimization formulation is presented and used to identify the topologies of minimum volume tensegrity structures designed to carry external applied loads. Binary variables and associated constraints are used to limit (usually to one) the number of compressive elements connecting a node. A computationally efficient two-stage procedure employing mixed integer linear programming (MILP) is used to identify structures capable of carrying both externally applied loads and the self-stresses present when these loads are removed. Although tensegrity structures are often regarded as inherently ‘optimal’, the presence of additional constraints in the optimization formulation means that they can never be more optimal than traditional, non-tensegrity, structures. The proposed procedure is programmed in a MATLAB script (available for download) and a range of examples are used to demonstrate the efficacy of the approach presented
An examination of global university rankings as a new mechanism influencing mission differentiation: the UK context
Since their emergence a decade ago, global university rankings have become a powerful force in higher education internationally. The majority of research studies on global rankings have examined the effects at institutional and national levels. This study offers a valuable perspective on the ways rankings (and other international benchmarks) are deployed at the intra-sector level, by UK higher education ‘mission groups’, to support different policy positions. The concept of object in activity theory is used to problematize the analysis. Critical discourse analysis is used as a methodological orientation to study the ways global rankings mediate the object in this context. The findings contribute to the current debate on whether rankings are promoting isomorphism in higher education sectors nationally, illustrating a differentiated engagement with rankings in the UK context. The relevance of the findings for policy-makers and institutional managers is discussed
“I Wasn’t Sure What It Meant to be Honest”—Formative Research towards a Physical Literacy Intervention for Preschoolers
Physical literacy (PL) as a concept is important in developing lifelong physical activity; however, there is little research exploring how PL can be developed during the preschool years. This two-phase qualitative study sought the insights of academics/expert practitioners and preschool staff towards PL in order to inform the design of future preschool PL interventions. Phase One comprised of nine semi-structured interviews with experts in the field of children’s physical activity and/or PL. Interview topics included perspectives on the concept of PL and recommendations for interventions targeted at improving preschool PL. Phase Two consisted of focus groups with practitioners from four local children’s centres. Focus groups explored perspectives on the feasibility and acceptability of proposed PL interventions. Interviews and focus groups were analysed by thematic analysis and means of representation, respectively. Findings revealed that whilst there was limited understanding about the concept of PL among preschool educators, knowledge of child development was evident and that all participants agreed that there was a need for further training for practitioners. Perceived barriers to promoting PL noted by practitioners included funding, policy, curricular priorities, parental opinions, and the preschool environment. It was recommended that interventions should be: (i) designed using a participatory approach including all key stakeholders, (ii) conducted over the long term, and (iii) incorporate opportunities for children to engage in free and outdoor play. Furthermore, any intervention should be flexible to allow for variation between children’s centres, aligned to current policy/children’s centre targets and provide training and resources in order to overcome perceived barriers.</jats:p
Toughening by nanostructure
Block copolymer modified epoxy resins have generated significant interest since it was demonstrated that the combination could lead to nanostructured thermosets through self-assembly. Over moderate to high polymer concentration the system behaves as expected for a block copolymer in a solvent selective for one block. Two types of copolymers have been studied: non-reactive and reactive modifiers. Morphologies such as copolymer vesicle and spherical/wormlike micelles can be formed under the appropriate conditions. The enhancement of the modified thermosets' mechanical properties depends on the morphology adopted by the polymers. Besides improving mechanical properties, the morphology was found to also have an effect on the glass transition in the studied systems. In this review we collect the available data on the block copolymers used to fabricate nanostructured epoxy resins and critically appraise the properties reported
News discourses on distant suffering: A critical discourse analysis of the 2003 SARS outbreak
News carries a unique signifying power, a power to represent events in particular ways (Fairclough, 1995). Applying Critical Discourse Analysis and Chouliaraki's theory on the mediation of suffering (2006), this article explores the news representation of the 2003 global SARS outbreak. Following a case-based methodology, we investigate how two Belgian television stations have covered the international outbreak of SARS. By looking into the mediation of four selected discursive moments, underlying discourses of power, hierarchy and compassion were unraveled. The analysis further identified the key role of proximity in international news reporting and supports the claim that Western news media mainly reproduce a Euro-American centered world order. This article argues that news coverage of international crises such as SARS constructs and maintains the socio-cultural difference between 'us' and 'them' as well as articulating global power hierarchies and a division of the world in zones of poverty and prosperity, danger and safety

Effect of a sport-for-health intervention (SmokeFree Sports) on smoking-related intentions and cognitions among 9-10 year old primary school children: a controlled trial.
BACKGROUND: Preventing children from smoking is a public health priority. This study evaluated the effects of a sport-for-health smoking prevention programme (SmokeFree Sports) on smoking-related intentions and cognitions among primary school children from deprived communities. METHODS: A non-randomised-controlled trial targeted 9-10 year old children from Merseyside, North-West England. 32 primary schools received a programme of sport-for-health activities over 7 months; 11 comparison schools followed usual routines. Data were collected pre-intervention (T0), and at 8 months (T1) and one year post-intervention (T2). Smoking-related intentions and cognitions were assessed using an online questionnaire. Intervention effects were analysed using multi-level modelling (school, student), adjusted for baseline values and potential confounders. Mixed-sex focus groups (n = 18) were conducted at T1. RESULTS: 961 children completed all assessments and were included in the final analyses. There were no significant differences between the two study groups for non-smoking intentions (T1: β = 0.02, 95 % CI = -0.08-0.12; T2: β = 0.08, 95 % CI = -0.02-0.17) or for cigarette refusal self-efficacy (T1: β = 0.28, 95 % CI = -0.11-0.67; T2: β = 0.23, 95 % CI = -0.07-0.52). At T1 there was a positive intervention effect for cigarette refusal self-efficacy in girls (β = 0.72, 95 % CI = 0.21-1.23). Intervention participants were more likely to 'definitely' believe that: 'it is not safe to smoke for a year or two as long as you quit after that' (RR = 1.19, 95 % CI = 1.07-1.33), 'it is difficult to quit smoking once started' (RR = 1.56, 95 % CI = 1.38-1.76), 'smoke from other peoples' cigarettes is harmful' (RR = 1.19, 95 % CI = 1.20-2.08), 'smoking affects sports performance' (RR = 1.73, 95 % CI = 1.59-1.88) and 'smoking makes 'no difference' to weight' (RR = 2.13, 95 % CI = 1.86-2.44). At T2, significant between-group differences remained just for 'smoking affects sports performance' (RR = 1.57, 95 % CI = 1.43-1.72). Focus groups showed that SFS made children determined to remain smoke free and that the interactive activities aided children's understanding of smoking harms. CONCLUSION: SFS demonstrated short-term positive effects on smoking attitudes among children, and cigarette refusal self-efficacy among girls. Although no effects were observed for non-smoking intentions, children said that SFS made them more determined not to smoke. Most children had strong intentions not to smoke; therefore, smoking prevention programmes should perhaps target early adolescents, who are closer to the age of smoking onset
Sex-Related Differences in the Association of Fundamental Movement Skills and Health and Behavioral Outcomes in Children
This study aimed to assess whether sex moderates the association of fundamental movement skills (FMS) and health and behavioral outcomes. In 170 children (10.6 ± 0.3 years; 98 girls), path-analysis was used to assess the associations of FMS (Get Skilled, Get Active) with perceived sports competence (Children and Youth - Physical Self-Perception Profile), time spent in vigorous-intensity physical activity (VPA), sedentary time and body mass index (BMI) z-score. For boys, object control skill competence had a direct association with perceived sports competence (β = 0.39; 95% CI: 0.21 to 0.57) and an indirect association with sedentary time, through perceived sports competence (β = -0.19; 95% CI: -0.09 to -0.32). No significant association was observed between FMS and perceived sports competence for girls, although locomotor skills were found to predict VPA (β = 0.18; 95% CI: 0.08 to 0.27). Perceived sports competence was associated with sedentary time, with this stronger for boys (β = -0.48; 95% CI: -0.64 to -0.31), than girls (β = -0.29; 95% CI: -0.39 to -0.19). The study supports a holistic approach to health-related interventions and highlights a key association of perceived sports competence and the time children spend sedentary
