Wayfinding: How Ecological Perspectives of Navigating Dynamic Environments Can Enrich Our Understanding of the Learner and the Learning Process in Sport

Wayfinding is the process of embarking upon a purposeful, intentional, and self-regulated journey that takes an individual from an intended region in one landscape to another. This process is facilitated through an individual’s capacity to utilise temporally structured, functional actions embedded within a particular environmental niche. Thus, individuals learn of their performance landscapes by experiencing them through interactions, detecting and exploiting its many features to ‘find their way’. In this opinion piece, we argue that these ecological and anthropological conceptualisations of human navigation can, metaphorically, deepen our understanding of the learner and the learning process in sport, viewed through the lens of ecological dynamics. Specifically, we consider sports practitioners as (learning) landscape designers, and learners as wayfinders; individuals who learn to skilfully self-regulate through uncharted fields (composed of emergent problems) within performance landscapes through a deeply embodied and embedded perception-action coupling. We contend that, through this re-configuration of the learner and the learning process in sport, practitioners may better enact learning designs that afford learners exploratory freedoms, learning to perceive and utilise available opportunities for action to skilfully navigate through emergent performance-related problems. We conclude the paper by offering two practical examples in which practitioners have designed practice landscapes that situate learners as wayfinders and the learning process in sport as wayfinding

‘Knowing as we go’: a Hunter-Gatherer Behavioural Model to Guide Innovation in Sport Science

Where do novel and innovative ideas in sport science come from? How do researchers and practitioners collectively explore the dynamic landscape of inquiry, problem, solution and application? How do they learn to skilfully navigate from current place and practice toward the next idea located beyond their current vantage point? These questions are not just of philosophical value but are important for understanding how to provide high-quality support for athletes and sport participants at all levels of expertise and performance. Grounded in concepts from social anthropology, and theoretically positioned within an ecological dynamics framework, this opinion piece introduces a hunter-gatherer model of human behaviour based on wayfinding, situating it as a conceptual guide for implementing innovations in sport science. Here, we contend that the embedded knowledge of a landscape that guides a successful hunting and gathering party is germane to the pragmatic abduction needed to promote innovation in sport performance, leading to the inquisition of new questions and ways of resolving performance-preparation challenges. More specifically, exemplified through its transdisciplinarity, we propose that to hunt ‘new ideas’ and gather translatable knowledge, sport science researchers and practitioners need to wayfind through uncharted regions located in new performance landscapes. It is through this process of navigation where individuals will deepen, enrich and grow current knowledge, ‘taking home’ new ideas as they find their way

Enskilment: an Ecological-Anthropological Worldview of Skill, Learning and Education in Sport.

The aim of this paper is to explore a different, more relational worldview of skill, learning and education in sport. To do this, we turn to the work of social anthropologist, Tim Ingold, leaning on the notion of enskilment, which proposes that learning is inseparable from doing and place. From this worldview, what is learned is not an established body of knowledge, transmitted into the mind of a passive recipient from an authorised being, but is a progressively deepening embodied-embedded attentiveness, where an individual learns to self-regulate by becoming more responsive to people and environmental features by 'looking, listening and feeling'. As we discuss, Ingold's perspectives on enskilment are rooted in the etymological connotations of education-ex-ducere, which roughly means 'to lead out'. In applying this notion to sport, we unpack three of its entangled components, taskscapes, guided attention, and wayfinding, detailing the implications of each for the growth of enskilled sports performers. To promote the translation of these ideas, in addition to encouraging their inquiry beyond the scope of what is discussed here, sporting examples are threaded throughout the paper

An ecological dynamics conceptualisation of physical ‘education’: Where we have been and where we could go next

Background: In this paper, we explore physical education from a relational worldview. Theoretically guided by an ecological dynamics framework, this perspective calls us to conceptualise ‘education’ in its etymological roots – ex-ducere – meaning ‘to lead’ an individual ‘out’ into the world. In doing so, an educator would employ a ‘softer’ pedagogy, seeking to guide the attention and encourage exploration of a less experienced individual toward the perception of things that can support, or regulate, their behaviours. This pedagogical approach could help learners to self regulate in the environment, becoming more responsive to emergent opportunities for action available. Theory: This is a pedagogy of exploration, search, discovery, invention and adaptation that is devised from three of the contributing theories to ecological dynamics: ecological psychology, dynamical systems theory and complexity sciences. Throughout this paper we show that this progressive view contrasts with the more traditional perspectives of physical education, grounded in established pedagogical approaches that are often pre-occupied with instilling idealised ways of moving in learners, typically at the expense of appreciating how the environment reciprocally shapes behaviour. Practical Implications: In an effort to support educators with integrating an ecological conceptualisation of PE into their practice we outline three cornerstones. We bring these ideas to life by concluding the paper with the presentation of three practical examples that transcends the physical educational journey from primary/elementary school through to secondary/ high schools. We exemplify how an ecological approach to PE can move us closer to achieving the aim of enabling children to lead a physically active life beyond the school gates

Factors contributing to the temperature beneath plaster or fiberglass cast material

<p>Abstract</p> <p>Background</p> <p>Most cast materials mature and harden via an exothermic reaction. Although rare, thermal injuries secondary to casting can occur. The purpose of this study was to evaluate factors that contribute to the elevated temperature beneath a cast and, more specifically, evaluate the differences of modern casting materials including fiberglass and prefabricated splints.</p> <p>Methods</p> <p>The temperature beneath various types (plaster, fiberglass, and fiberglass splints), brands, and thickness of cast material were measured after they were applied over thermometer which was on the surface of a single diameter and thickness PVC tube. A single layer of cotton stockinette with variable layers and types of cast padding were placed prior to application of the cast. Serial temperature measurements were made as the cast matured and reached peak temperature. Time to peak, duration of peak, and peak temperature were noted. Additional tests included varying the dip water temperature and assessing external insulating factors. Ambient temperature, ambient humidity and dip water freshness were controlled.</p> <p>Results</p> <p>Outcomes revealed that material type, cast thickness, and dip water temperature played key roles regarding the temperature beneath the cast. Faster setting plasters achieved peak temperature quicker and at a higher level than slower setting plasters. Thicker fiberglass and plaster casts led to greater peak temperature levels. Likewise increasing dip-water temperature led to elevated temperatures. The thickness and type of cast padding had less of an effect for all materials. With a definition of thermal injury risk of skin injury being greater than 49 degrees Celsius, we found that thick casts of extra fast setting plaster consistently approached dangerous levels (greater than 49 degrees for an extended period). Indeed a cast of extra-fast setting plaster, 20 layers thick, placed on a pillow during maturation maintained temperatures over 50 degrees of Celsius for over 20 minutes.</p> <p>Conclusion</p> <p>Clinicians should be cautious when applying thick casts with warm dip water. Fast setting plasters have increased risk of thermal injury while brand does not appear to play a significant role. Prefabricated fiberglass splints appear to be safer than circumferential casts. The greatest risk of thermal injury occurs when thick casts are allowed to mature while resting on pillow.</p

A case of bilateral luxatio erecta

Luxatio erecta is an uncommon form of glenohumeral dislocation. Cases of bilateral inferior shoulder dislocation (luxatio erecta) are very rare, and only ten cases have been described in literature. We describe a case of a woman with bilateral luxatio erecta of the shoulders treated with close reduction, immobilization and rehabilitation. The patient had fallen downstairs while clinging to both lateral banisters

Unusual inferior dislocation of shoulder: reduction by two-step maneuver: a case report

Dislocation of the shoulder is the commonest of all large joint dislocations. Inferior dislocation constitutes 0.5% of all shoulder dislocations. It characteristically presents with overhead abduction of the arm, the humerus being parallel to the spine of scapula. We present an unusual case of recurrent luxatio erecta in which the arm transformed later into an adducted position resembling the more common anterior shoulder dislocation. Such a case has not been described before in English literature. Closed reduction by the two-step maneuver was successful with a single attempt. MRI revealed posterior labral tear and a Hill-Sachs variant lesion on the superolateral aspect of humeral head. Immobilisation in a chest-arm bandage followed by physiotherapy yielded excellent results. The case is first of its kind; the unusual mechanism, unique radiological findings and alternate method of treatment are discussed

Developing Maintenance Cultures in UN Police Peacekeeping Operations

This report provides an analysis and evaluation of maintenance cultures in United Nations Police Contributing Countries (PCC) receiving funding for Formed Police Units from the United States. The US Department of State, Bureau of International Narcotics and Law Enforcement Affairs (INL) recognized a marked lack of research on maintenance cultures in police agencies receiving foreign funding and sought to build a base of knowledge to aid in creating and sustaining maintenance cultures within these organizations. The INL also requested analysis and evaluation of maintenance cultures in five specific African PCCs (Cameroon, Ghana, Rwanda, Senegal, and Togo), as well as recommendations to create and sustain maintenance cultures specific to these countries. By establishing effective maintenance cultures, INL seeks to ensure that equipment purchased with funding from the United States will operate effectively throughout the manufacturer's estimated life-span

This article will review common causes of chronic anterior knee pain in the pediatric population with a focus on patellofemoral pain

Theoretical description of deformed proton emitters: nonadiabatic coupled-channel method

The newly developed nonadiabatic method based on the coupled-channel Schroedinger equation with Gamow states is used to study the phenomenon of proton radioactivity. The new method, adopting the weak coupling regime of the particle-plus-rotor model, allows for the inclusion of excitations in the daughter nucleus. This can lead to rather different predictions for lifetimes and branching ratios as compared to the standard adiabatic approximation corresponding to the strong coupling scheme. Calculations are performed for several experimentally seen, non-spherical nuclei beyond the proton dripline. By comparing theory and experiment, we are able to characterize the angular momentum content of the observed narrow resonance.Comment: 12 pages including 10 figure
