Playing social justice: How do early childhood teachers enact the right to play through resistance and subversion?
In this paper we narrate how two teachers enact playful pedagogies by resisting the single story of formalised learning discourses in early childhood education and care. Playful learning is well established in international literature and children have the right to play. Yet in contemporary outcomes-driven policy, adult-led formalised teaching has become normalised at the expense of child-initiated play. Play is thus marginalised; positioned as a privilege rather than as a right and dependent on views of children as capable holders of rights. Here, we position play in relation to democracy, equity and social justice by storying how teachers’ circumvent scrutiny to facilitate the right to play and we argue this as a fruitful sub-context for resistance. From this perspective, teachers’ resistances do not just enable play, they embody and enact representative and democratic justice. Firstly, teachers story representative forms of social justice as ‘being the right thing’ in making play happen. Secondly, teachers enact democratic forms of social justice through resistance actions of ‘doing the right thing’ that entangle an emotional vulnerability to scrutiny. Adopting alternative resistance positions shifts play beyond a privilege and creates transformational spaces for social justice where time, space and materiality have a role to play. We call on teachers and educators to deepen their critical awareness of the narrowness of a single story of learning and the rich relationships between rights and play agendas. We assert that teachers’ resistances can enable playful pedagogies and act as hopeful storytelling of social justice as serious play.
Storying hopeful resistances to datafication:Cracks, spacetimematterings and figurations of agency within the more-than-human ecologies of early childhood education and care
In this paper, we ponder the ecologies of spacetimematterings folded into resistance practices and its relationality with figurations of agency outside and beyond datafication agendas. Accountability cultures bound up with datafication have consequences that include a diminished agency for both children and educators. According to Holloway (2010) enactments of resistance can cause cracks to appear that forge creative spaces where different kinds of doings related to agency emerge. The context, potentiality and storyings of cracking encounters is where our interest lies. To ponder crackings, we play with feminist posthuman and materialist theorising with research-creation approaches to notice resistances as material-discursive intra-actions amongst the lively materiality of educational life. From there we notice resistance practices as ecologies. Those ecologies are complex and lively yet often concealed in more-than-human cracks by the grand narrative of datafication. Through storytelling, we re-imagine these cracks as dynamic resistances, often unresolving the relationality between power and the collective more-than-human modes of resistance we witnessed. Different kinds of noticing mattered and amplifying the sharing of resistance stories brings attention to hopeful agencies already and always at work. Sharing stories can strengthen the connectivity of resistances to datafication and build a stronger autonomy and agency for early childhood education and care. Our provocation is to pay attention to the spacetimematterings of ecologies where resistance practices are already at work cracking cracks for different doings. From there, further activisms can mobilise a larger fracturing to the dominance of datafication narratives
Food insecurity and severe mental illness: understanding the hidden problem and how to ask about food access during routine healthcare
SUMMARY Food insecurity occurs when an individual lacks the financial resources to ensure reliable access to sufficient food to meet their dietary, nutritional and social needs. Adults living with mental ill health, particularly severe mental illness, are more likely to experience food insecurity than the general adult population. Despite this, most interventions and policy reforms in recent years have been aimed at children and families, with little regard for other vulnerable groups. Initiating a conversation about access to food can be tricky and assessing for food insecurity does not happen in mental health settings. This article provides an overview of food insecurity and how it relates to mental ill health. With reference to research evidence, the reader will gain an understanding of food insecurity, how it can be assessed and how food-insecure individuals with severe mental illness can be supported. Finally, we make policy recommendations to truly address this driver of health inequality.</jats:p
Comparison of flow and dispersion properties of free and wall turbulent jets for source dynamics characterisation
The objective of this paper is to provide an investigation, using large eddy simulations, into the dispersion of aircraft jets in co-flowing take-off conditions. Before carrying out such study, simple turbulent plane free and wall jet simulations are carried out to validate the computational models and to assess the impact of the presence of the solid boundary on the flow and dispersion properties. The current study represents a step towards a better understanding of the source dynamics behind an airplane jet engine during the take-off and landing phases. The information provided from these simulations can be used for future improvements of existing dispersion models
Wearable devices can predict the outcome of standardized 6-minute walk tests in heart disease
Wrist-worn devices with heart rate monitoring have become increasingly popular. Although current guidelines advise to consider clinical symptoms and exercise tolerance during decision-making in heart disease, it remains unknown to which extent wearables can help to determine such functional capacity measures. In clinical settings, the 6-minute walk test has become a standardized diagnostic and prognostic marker. We aimed to explore, whether 6-minute walk distances can be predicted by wrist-worn devices in patients with different stages of mitral and aortic valve disease. A total of n = 107 sensor datasets with 1,019,748 min of recordings were analysed. Based on heart rate recordings and literature information, activity levels were determined and compared to results from a 6-minute walk test. The percentage of time spent in moderate activity was a predictor for the achievement of gender, age and body mass index-specific 6-minute walk distances (p < 0.001; R2 = 0.48). The uncertainty of these predictions is demonstrated
Gene expression associated with early and late chronotypes in Drosophila melanogaster
The circadian clock provides the temporal framework for rhythmic behavioral and metabolic functions. In the modern era of industrialization, work, and social pressures, clock function is jeopardized, and can result in adverse and chronic effects on health. Understanding circadian clock function, particularly individual variation in diurnal phase preference (chronotype), and the molecular mechanisms underlying such chronotypes may lead to interventions that could abrogate clock dysfunction and improve human (and animal) health and welfare. Our preliminary studies suggested that fruit-flies, like humans, can be classified as early rising “larks” or late rising “owls,” providing a convenient model system for these types of studies. We have identified strains of flies showing increased preference for morning emergence (Early or E) from the pupal case, or more pronounced preference for evening emergence (Late or L). We have sampled pupae the day before eclosion (fourth day after pupariation) at 4 h intervals in the E and L strains, and examined differences in gene expression by RNA-seq. We have identified differentially expressed transcripts between the E and L strains, which provide candidate genes for subsequent studies of Drosophila chronotypes and their human orthologs
Use of stochastic simulation to evaluate the reduction in methane emissions and improvement in reproductive efficiency from routine hormonal interventions in dairy herds
This study predicts the magnitude and between herd variation in changes of methane emissions and production efficiency associated with interventions to improve reproductive efficiency in dairy cows. Data for 10,000 herds of 200 cows were simulated. Probability of conception was predicted daily from the start of the study (parturition) for each cow up to day 300 of lactation. Four scenarios of differing first insemination management were simulated for each herd using the same theoretical cows: A baseline scenario based on breeding from observed oestrus only, synchronisation of oestrus for pre-set first insemination using 2 methods, and a regime using prostaglandin treatments followed by first insemination to observed oestrus. Cows that did not conceive to first insemination were re-inseminated following detection of oestrus. For cows that conceived, gestation length was 280 days with cessation of milking 60 days before calving. Those cows not pregnant after 300 days of lactation were culled and replaced by a heifer. Daily milk yield was calculated for 730 days from the start of the study for each cow. Change in mean reproductive and economic outputs were summarised for each herd following the 3 interventions. For each scenario, methane emissions were determined by daily forage dry matter intake, forage quality, and cow replacement risk. Linear regression was used to summarise relationships. In some circumstances improvement in reproductive efficiency using the programmes investigated was associated with reduced cost and methane emissions compared to reliance on detection of oestrus. Efficiency of oestrus detection and the time to commencement of breeding after calving influenced variability in changes in cost and methane emissions. For an average UK herd this was a saving of at least £50 per cow and a 3.6% reduction in methane emissions per L of milk when timing of first insemination was pre-set
Development of a Molecular Snail Xenomonitoring Assay to Detect Schistosoma haematobium and Schistosoma bovis Infections in their Bulinus Snail Hosts.
Schistosomiasis, a neglected tropical disease of medical and veterinary importance, transmitted through specific freshwater snail intermediate hosts, is targeted for elimination in several endemic regions in sub-Saharan Africa. Multi-disciplinary methods are required for both human and environmental diagnostics to certify schistosomiasis elimination when eventually reached. Molecular xenomonitoring protocols, a DNA-based detection method for screening disease vectors, have been developed and trialed for parasites transmitted by hematophagous insects, such as filarial worms and trypanosomes, yet few have been extensively trialed or proven reliable for the intermediate host snails transmitting schistosomes. Here, previously published universal and Schistosoma-specific internal transcribed spacer (ITS) rDNA primers were adapted into a triplex PCR primer assay that allowed for simple, robust, and rapid detection of Schistosoma haematobium and Schistosoma bovis in Bulinus snails. We showed this two-step protocol could sensitively detect DNA of a single larval schistosome from experimentally infected snails and demonstrate its functionality for detecting S. haematobium infections in wild-caught snails from Zanzibar. Such surveillance tools are a necessity for succeeding in and certifying the 2030 control and elimination goals set by the World Health Organization
Direct observations of a surface eigenmode of the dayside magnetopause
The abrupt boundary between a magnetosphere and the surrounding plasma, the magnetopause, has long been known to support surface waves. It was proposed that impulses acting on the boundary might lead to a trapping of these waves on the dayside by the ionosphere, resulting in a standing wave or eigenmode of the magnetopause surface. No direct observational evidence of this has been found to date and searches for indirect evidence have proved inconclusive, leading to speculation that this mechanism might not occur. By using fortuitous multipoint spacecraft observations during a rare isolated fast plasma jet impinging on the boundary, here we show that the resulting magnetopause motion and magnetospheric ultra-low frequency waves at well-defined frequencies are in agreement with and can only be explained by the magnetopause surface eigenmode. We therefore show through direct observations that this mechanism, which should impact upon the magnetospheric system globally, does in fact occur
