‘I don’t want my parents’ respect going down the drain’: South Asian, Muslim young women negotiating family and physical activity.

Young women’s relationship with physical activity has been explored extensively, yet the focus is often upon young women who are White. This paper considers South Asian, Muslim young women’s experiences of physical activity and how these are influenced by family. A ‘middle ground’ feminist approach is used, drawing upon the work of Hill Collins [(2000). Black feminist thought: Knowledge, consciousness, and the politics of empowerment. London: Routledge] and Hamzeh [(2012). Pedagogies of deveiling: Muslim girls and the hijab discourse (critical AQ2 construction). Charlotte, NC: Information Age Publishing were generated with 13 young women using participatory approaches in focus group settings, and individual interviews. This research highlights how the young women’s families can both enable and challenge opportunities and involvement in physical activity. The paper discusses how gender and religion intersect with family and wider community to influence experiences in multiple, diverse and fluid ways. The young women’s narratives suggest that experiences are not determined solely by these influences; rather, they emerge as active agents negotiating different contextual challenges in their quest to be physically active

Enhancement of rare-earth--transition-metal exchange interaction in Pr2_{2}Fe17_{17} probed by inelastic neutron scattering

The fundamental magnetic interactions of Pr$_{2}$Fe$_{17}$ are studied by inelastic neutron scattering and anisotropy field measurements. Data analysis confirms the presence of three magnetically inequivalent sites, and reveals an exceptionally large value of the exchange field. The unexpected importance of $J$-mixing effects in the description of the ground-state properties of Pr$_{2}$Fe$_{17}$ is evidenced, and possible applications of related compounds are envisaged.Comment: 4 RevTeX pages, 4 EPS figures.

The socialization and participation of Deaflympians in sport

D/deaf people are often ignored within sports research. This paper centralizes the experiences of four D/deaf athletes who have competed in the Deaflympics and offers some insights about their socialization into sport. The key questions addressed are: (1) What are the key factors enabling D/deaf athletes’ involvement and progression in elite D/deaf sport? (2) What are the key challenges D/deaf athletes face when participating and progressing in D/deaf sport? Findings from the interviews suggest that early specialization into sport does not include exposure to Deaf sport

Messy methods: Making sense of participatory research with young people in PE and sport

Participatory research with young people has become an approach increasingly adopted by researchers within PE and sport. In this paper, we draw on our research diaries to collectively reflect on our experiences of attempting to work in participatory ways. Although we each work with different young people and have adopted differing participatory approaches, there are similarities in our research experiences. This includes recurring accounts of ‘muddling through’ and messiness occupying our reflections. We are also struck by the absence of concern within the literature to reveal the messiness of research. In light of our shared musings about participatory research with different young people, this paper offers some preliminary thoughts about our experiences of dealing with this messiness. We take as our focus the increasing concerns to support rights-based research that advocates inclusion, participation and empowerment, and draw on our research to explore how these features were worked towards. In these discussions we are open about the limitations of the research, challenges encountered and the resultant messiness arising. Our conclusion turns to what it might mean if researchers were more transparent about the usually unpredictable, messy and confusing situations that arise in the practice of doing participatory research with young people

Electrosprayed nanoparticle delivery system for controlled release

This study utilises an electrohydrodynamic technique to prepare core-shell lipid nanoparticles with a tunable size and high active ingredient loading capacity, encapsulation efficiency and controlled release. Using stearic acid and ethylvanillin as model shell and active ingredients respectively, we identify the processing conditions and ratios of lipid:ethylvanillin required to form nanoparticles. Nanoparticles with a mean size ranging from 60 to 70 nm at the rate of 1.37 × 109 nanoparticles per minute were prepared with different lipid:ethylvanillin ratios. The polydispersity index was ≈ 21% and the encapsulation efficiency ≈ 70%. It was found that the rate of ethylvanillin release was a function of the nanoparticle size, and lipid:ethylvanillin ratio. The internal structure of the lipid nanoparticles was studied by transmission electron microscopy which confirmed that the ethylvanillin was encapsulated within a stearic acid shell. Fourier transform infrared spectroscopy analysis indicated that the ethylvanillin had not been affected. Extensive analysis of the release of ethylvanillin was performed using several existing models and a new diffusive release model incorporating a tanh function. The results were consistent with a core-shell structure

The hows and whys of gendered grouping practices in primary physical education in England

Background: Single- and mixed-sex grouping have long been a focus of attention in physical education (PE) and are matters often at the fore of discussions about curriculum planning, teaching, and learning. Nonetheless, there remains little consensus or guidance on which approach (or combination of approaches) should be preferred in PE in primary and secondary schools in England. Further, while single- and mixed-sex grouping have been extensively researched in PE in secondary schools, hitherto there remains an absence of research examining these practices in PE in primary schools. This research sought to address gaps in the literature to build a stronger evidence-base for decisions about gendered grouping practices in PE. Specifically, the study was designed to provide a snapshot of current single- and mixed-sex grouping arrangements in primary PE in England. Method: Data were collected via an online survey which was administered to all state-funded mainstream and special schools providing for children in Key Stage 1 (aged 5–7) and/or Key Stage 2 (aged 7–11) in the North-East of England (917 at the time of study). A total of 254 surveys were completed giving a response rate of 27.7%. Results: The responses indicate that nearly all schools were using mixed-sex grouping for PE, with children typically remaining in their mixed-sex form class and taught the same curriculum activities by their class teacher. Notably, no schools were using single-sex grouping for all PE lessons, although some were teaching combinations of single- and mixed-sex classes across different year groups and/or different activities of the curriculum. The responses also challenge the traditional dichotomous representation of single- and mixed-sex grouping by showing that some schools were grouping children into smaller single-sex groups within mixed-sex PE classes, particularly in activities requiring bodily contact. Some schools were also organising children into smaller mixed-sex groups within mixed-sex PE classes to encourage boys and girls to work together and support one another in their learning. Reported reasons for current grouping arrangements reflected both pragmatic considerations and perceived educational benefits of particular approaches, including school timetabling and consideration of gender equity in curriculum provision in PE. Conclusion: The conclusion calls for further research to explore the efficacy of single- and/or mixed-sex grouping in supporting and meeting the needs of all children in primary PE. Relatedly, we also highlight the importance of intersectional perspectives being brought to single- and mixed-sex grouping debates to inform the development of more nuanced, evidence-based policies and practices that promote inclusion and celebrate the diversity of children. We further suggest a need for research and policy to reconsider the language used in grouping practices to reflect commitments to gender diversity and gender equity

Development of a Nanodroplet Formulation for Triggered Release of BIO for Bone Fracture Healing

Impaired fracture healing impacts patients’ quality of life and imposes a financial burden on healthcare services. Up to 10% of bone fractures result in delayed/non-union fractures, for which new treatments are urgently required. However, systemic delivery of bone anabolic molecules is often sub-optimal and can lead to significant side effects. In this study, we developed ultrasound (US) responsive nano-sized vehicles in the form of perfluorocarbon nanodroplets (NDs), as a means of targeting delivery of drugs to localised tissues. We tested the hypothesis that NDs could stably encapsulate BIO (GSK-3β inhibitor), which could then be released upon US stimulation to activate Wnt signalling and induce ossification. NDs (~280 nm) were prepared from phospholipids and liquid perfluorocarbon and their stability and drug loading was studied by NTA (Nano Tracking Analysis) and HPLC. ND cytotoxicity was assessed in patient-derived bone marrow stromal cells (BMSCs) with Alamar Blue (24 h), and in vitro bioactivity of BIO-NDs was evaluated in a 3T3 Wnt-pathway reporter cell line with luciferase readout. To investigate the acoustic behaviour of NDs, 2% agarose (LM) containing NDs was injected into a bespoke bone fracture model (Sawbones) of various geometries and stimulated by US (1 MHz, 5% duty cycle, 1 MPa, 30 s), allowing the simultaneous capture of optical images and acoustic emissions. Femoral bone hole defects (1–2 mm) were made in WT-MF1 mice (age: 8–12 wks) and DiR-labelled NDs (100 µL, 109 NDs/mL, i.v.) were injected post-fracture to determine biodistribution by IVIS imaging. NDs were stable (4 and 37 °C) and retained >90% BIO until US was applied, which caused ~100% release. ND exposure up to a concentration of 109 NDs/mL showed no cytotoxicity (24 h). BIO-loaded NDs induced Wnt pathway activation in a dose dependent manner. Biodistribution of DiR-NDs in a femoral bone hole defect model in mice demonstrated increased localisation at the fracture site (~2-fold relative to that found in healthy mice or contralateral femurs at 48 h)
