Movement learning has become a prominent issue in recent sport pedagogy research, including a particular concern about the new perspectives of movement learning. The turn towards new perspectives is partly spurred by discontent with the conventional perspectives of movement learning. The purpose of the article is to explore a journey into the kinescape of unicycling. The article can be seen as a case study of what it means to learn (how) to unicycle for one student teacher in the midst of a pedagogical research module and with the aid of the Deleuzian notion of a triadic relationship between percepts, affects and concepts. The analysis points to how a student, in the midst of material features such as equipment, the sport hall, other people, and instructional video clips, is mapping connections between concepts (what unicycling can be), percepts (a-ha moments) and affects (what moves him to continue practising unicycling), in ways that allow him to learn to unicycle with astonishing pace. His practising of unicycling is guided by particular strategies for exploration and experimentation that his experiences of board culture offer him. Rather than any general principles of movement learning, of importance here are the particular ways in which kinesio-cultural exploration may offer non-linear resources for movement learning. We conclude that this approach to learning may stimulate pedagogies that are not only effective but also more inclusive because they are more creative and more open than linear approaches to movement learning.

AbstractThis manuscript investigates the design-for-control (DfC) problem of minimizing pressure induced leakage and maximizing resilience in existing water distribution networks. The problem consists in simultaneously selecting locations for the installation of new valves and/or pipes, and optimizing valve control settings. This results in a challenging optimization problem belonging to the class of non-convex bi-objective mixed-integer non-linear programs (BOMINLP). In this manuscript, we propose and investigate a method to approximate the non-dominated set of the DfC problem with guarantees of global non-dominance. The BOMINLP is first scalarized using the method of $$\epsilon $$ ϵ -constraints. Feasible solutions with global optimality bounds are then computed for the resulting sequence of single-objective mixed-integer non-linear programs, using a tailored spatial branch-and-bound (sBB) method. In particular, we propose an equivalent reformulation of the non-linear resilience objective function to enable the computation of global optimality bounds. We show that our approach returns a set of potentially non-dominated solutions along with guarantees of their non-dominance in the form of a superset of the true non-dominated set of the BOMINLP. Finally, we evaluate the method on two case study networks and show that the tailored sBB method outperforms state-of-the-art global optimization solvers.

The objective of this case study was to experimentally manipulate the impact on arousal and recall of two characteristics frequently occurring in gruesome depictions of body parts in smoking cessation advertisements: the presence or absence of an external physical insult to the body part depicted; whether or not the image contains a clear figure/ground demarcation. Three hundred participants (46% male, 54% female; mean age 27.3 years, SD = 11.4) participated in a two-stage online study wherein they viewed and responded to a series of gruesome 4-s video images. Seventy-two video clips were created to provide a sample of images across the two conditions: physical insult versus no insult and clear figure/ground demarcation versus merged or no clear figure/ground demarcation. In stage one, participants viewed a randomly ordered series of 36 video clips and rated how “confronting” they considered each to be. Seven days later (stage two), to test recall of each video image, participants viewed all 72 clips and were asked to identify those they had seen previously. Images containing a physical insult were consistently rated more confronting and were remembered more accurately than images with no physical insult. Images with a clear figure/ground demarcation were rated as no more confronting but were consistently recalled with greater accuracy than those with unclear figure/ground demarcation. Makers of gruesome health warning television advertisements should incorporate some form of physical insult and use a clear figure/ground demarcation to maximize image recall and subsequent potential advertising effectiveness.
