Picture This: A new sociocultural ‘layered listening framework’ that promotes participation through documentary photography, with young children whose families have migrated to the UK.
No full textHigh quality, equitable early childhood education and care (ECEC) is significant for the participation of children whose families have migrated to the UK. The rich lived experiences, perspectives and funds of knowledge of newly arrived children are largely invisible and there is an increased risk of social exclusion as a consequence. Drawing upon the findings of a three-year study using child-led photography and photo story books to explore three- to four-year-old children’s funds of knowledge, this chapter offers an original theoretical and pedagogic ‘layered listening framework’ (LLF) that blurs sociocultural theory and visual theories for deep listening with young children. This novel conceptualisation, comprising intuitive and wise photography; ambiguity; photographing democratically and ‘elastic spaces’ suggests an expanded guide for understanding how children as ‘photographer-authors’ co-create diverse perspectives about their lived experiences as pedagogical possibilities. Further research into photography is recommended for researchers and practitioners to develop ‘elastic spaces’ of ongoing dialogue and alternative ways of seeing in culturally responsive ECEC and beyond. Such possibilities have the potential for challenging deficit perspectives of diversity by building democratic relationships of trust and reciprocity, with and for strong, resilient communities with hearts as well as minds
Comparing indoor tracking of golf ball and club metrics: Consistency and absolute agreement of the Flightscope Mevo+ and Trackman 4 launch monitors
Full text linkBackground
This study aimed to compare the Flightscope Mevo + launch monitor against a previously validated system (Trackman 4) during full golf swings in an indoor setting.
Methods
Mevo+ and Trackman 4 were compared concurrently for driver (n = 118, 118, 174 shots, respectively). Intraclass correlation coefficients (ICC) reported consistency and absolute agreement. Bland–Altman plots reported limits of agreement.
Results
Moderate to excellent consistency was reported for all values for driver (ICC = 0.66–0.996), 7-iron (ICC = 0.50–0.996) and pitching wedge (ICC = 0.55–1.00) except angle of attack which was poor for both 7-iron and pitching wedge (ICC = 0.06 & 0.03, respectively). For absolute agreement, Mevo + demonstrated moderate to excellent levels for most driver (ICC range = 0.58–0.98), 7-iron (ICC range = 0.83–0.94) and pitching wedge (ICC range = 0.77–0.999) variables. Driver swing plane (ICC absolute = 0.24), 7-iron angle of attack, clubhead speed, dynamic loft and spin rate (ICC absolute = 0.02, 0.44, 0.23, 0.49, 0.42, respectively) and pitching wedge angle of attack, dynamic loft, and swing plane (ICC absolute = 0.01, 0.25, 0.43, respectively) had poor agreement.
Conclusion
Mevo+ is consistent with Trackman 4 for all variables except angle of attack. It does however provide different absolute values, but usually in a consistent, systematic manner, across a number of variables. Coaches, club fitters, golfers, and scientists should be aware of these systematic differences when attempting to compare performance across launch monitors or when solely using the Mevo + system to aid performance, club building and fitting, or for research purposes
Porous sound absorbing materials from natural sources: data and modelling
Full text linkThis study reports porosity, flow resistivity, and normal incidence sound absorption spectra for samples fabricated from plant fibers, crushed fruit stones, chopped nut shells, and wood-cement composites. The Johnson–Champoux–Allard (JCA) model has been used to fit measured data and extract microstructural parameters such as tortuosity and characteristic lengths. An alternative, semi-analytical approach based on a model for a log normal size distribution of non-uniform cylindrical pores (NUPSD) is proposed. It uses porosity, flow resistivity, and the frequency of the first quarterwavelength resonance to estimate tortuosity. Also, it enables estimates of thermal permeability for making predictions with the Johnson-Champoux-Allard-Lafarge (JCAL) model. It avoids the need for direct fitting and provides comparable predictions. Typically, it predicts higher values of tortuosity than those resulting from fitting the JCA model. For many samples, particularly those with fibrous structure, the NUPSD-based predictions agree better with measured spectra than predictions based on JCA model fitting. The results indicate that the materials made from plant fibers are better sound absorbers than materials made from wood chips, wood cement, crushed fruit stones or chopped nut shells. Those with the higher tortuosity, implying broader pore size distributions, are more useful as sound absorbers for building applications
Build a sense of belonging in online learning environments
No full textThis chapter describes three projects that have piloted different ways to create a sense of belonging in an online academic setting. The Law School Peer-Mentoring Project uses technology to connect students with each other to develop supportive communities. The Law School Belonging Project takes a programme-wide approach through online events to provide opportunities for peer and staff interaction to create a sense of belonging. Finally, the Business School’s Belonging in Business Project has created a digital space where students can interact synchronously and asynchronously to foster connections.
The chapter explains the findings from the evaluations of these projects and the reflections of the practitioners running them. It includes practical advice and guidance for other education providers who may wish to develop their own intervention to create a sense of belonging for students within an online or blended education environment
Early Observations of New Active Asteroid 2025 VZ<sub>8</sub>
Full text linkWe report observations of main-belt asteroid 2025 VZ8 using multiple telescopes from UT 2025 November 24 to UT 2025 December 23 that confirm the presence of visible comet-like activity. These observations were motivated by online reports that an abrupt brightening event may have led to the object’s discovery on UT 2025 November 9. In all observations reported here, the object displays a tapered tail approximately 3″ long aligned with the antisolar direction. The object has an asteroidal Tisserand parameter value with respect to Jupiter (TJ = 3.371), and is thus considered an active asteroid. We measure an average apparent r′ -band magnitude of mr ∼ 21.6 mag over the reported observing period. Due to the sudden appearance of activity far from perihelion, we suggest that the activity is more likely due to an impact or rotational destabilization, rather than sublimation
Experimental Evaluation of Turning AISI 304 Using Minimum Quantity Lubrication With Vegetable‐Based Green Cutting Fluids
No full textCutting fluids play a crucial role in dissipating the heat generated during machining operations, contributing to improved service life and machinability of tools and workpieces. Even though commercially available conventional cutting fluids are effective in serving their intended roles during the machining process, they are non‐biodegradable. Previous researchers have introduced a variety of environmentally friendly alternatives, among which green cutting fluids stand out due to their biodegradability and availability. The present study focuses on a comparative assessment of the machining performance of green cutting fluids, made from oil‐water emulsions derived from coconut oil, sunflower oil, and palm oil, with a conventional cutting fluid (MAK Sherol B) during the turning operation of AISI 304 stainless steel. Tween 20 is used as the emulsifying agent for preparing oil‐water emulsion. The machining performance was investigated by examining the impact of these cutting fluids on cutting speed, feed rate, and depth of cut on tool tip interface temperature, surface roughness, and cutting force during the turning process. Surface roughness values are determined using surface profilometry and Atomic Force Microscopy (AFM). The results indicate that palm oil has rendered the lowest cutting force and cutting temperature with improved surface quality under higher feed rates, cutting speeds, and depths of cut as compared with sunflower oil, coconut oil, and conventional cutting fluid
Long-term revitalisation of coastal fisheries in Fukushima Prefecture: Insights from a deliberative Q-methodology exercise
Full text linkThe recovery of fisheries in coastal Fukushima Prefecture, Japan reflects long-term challenges faced by coastal communities following major environmental disasters. Long-term social, cultural and economic impacts highlight the need for a just recovery, prioritising requirements and perspectives of the most affected and offering opportunity for recovery and transformation. However, a just recovery requires sustained policy support, aligning with what different sections of the community aspire to. We therefore engaged different sectors of the fishing community in Iwaki, Fukushima Prefecture in an exploratory collaborative Q-Methodology exercise, to identify divergence and agreement on priorities for long-term recovery in the locality. Our results show that whilst ‘the community’ is never homogenous, a just recovery may depend as much on understanding people outside the community – such as distant consumers – as those in it. We also found that place identity can remain strong across the community in the face of major environmental change; and that divergence over how to proceed with ‘recovery’ may only emerge after the initial ‘emergency’ response period has passed. We make three tentative recommendations about how existing policy could better support just recovery in Iwaki and contexts like it. One is continuing core support for reform of infrastructure and distribution systems to transform local economies. Second is enabling locally-driven messaging about quality of produce, over and above technical safety information. Third is creating processes to engage intermediaries in long-term environmental monitoring to support evidence-informed decision-making
A Zipf-preserving, long-range correlated surrogate for written language and other symbolic sequences
Full text linkExamining anomalous summer carbonyl sulfide emissions in a boreal forest after thinning
No full textCarbonyl sulfide (COS) is gaining interest as a proxy for gross primary productivity (GPP). Thinning of the Hyytiälä (Finland) forest in the winter of 2019–2020 altered the response of COS fluxes to environmental conditions in the summer of 2021. For the first time, extended periods of ecosystem-scale COS emissions were observed in a boreal forest. The warm and dry conditions in the summer of 2021 reduced the COS uptake by the canopy and elevated soil abiotic COS production. However, the reduction in canopy uptake and the increase in soil production do not fully explain the observed ecosystem-level emissions. The analysis suggests an unidentified, homogeneously distributed COS source in the eddy covariance footprint area, potentially from the photodegradation of forest floor litter and cutting residue from thinning. Such a source in a boreal forest stand warrants further source apportionment studies to effectively use COS as a proxy for GPP
