An evaluation of personalised insoles developed using additive manufacturing

Abstract

The aim of the study was to evaluate the short and medium term use of personalised insoles, produced by combining additive manufacturing (AM) with three-dimensional (3-D) foot scanning and computer aided design (CAD) systems. For that, 38 runners (19 pairings) were recruited. The experimental conditions were: personalised and control. The personalised condition consisted of trainers fitted with personalised glove fit insoles manufactured using AM and using foot scans to match the plantar geometry of the feet. The control condition consisted of the same trainers fitted with insoles also manufactured using AM but using scans of the original insole shape. Participants were allocated to one of the experimental conditions and wore the trainers for 3 months. Over this period they attended three laboratory sessions (at months 0, 1.5 and 3) and completed an Activity Diary after each training session. The footwear was evaluated in terms of discomfort and biomechanics. Lower discomfort ratings were found in the heel area (P ≤ 0.05) and for overall fit (P ≤ 0.05), with the personalised insole. However, discomfort was reported under the arch region for both conditions. With regard to the biomechanical data, differences between conditions were detected for ankle dorsiflexion at footstrike (P ≤ 0.05), maximum ankle eversion (P ≤ 0.05) and peak mean pressure under the heel (P ≤ 0.01): the personalised condition had lower values which may reduce injury risk. The personalisation of the geometry of insoles through advances in AM together with 3-D scanning and CAD technologies can provide benefits and has potential.     

The One World, One Science Argument

The one world, one science argument (so named by Rescher) isadvanced by Carl Sagan and others to support the thesis thatwe will be able to learn to converse with intelligent extraterrestrialsif and when we encounter them. The prima facie obstacle to extraterrestrialcommunication is that the aliens’ culture and geographyare bound to be so different from ours that we would find itextremely difficult, if not practically impossible, to finda common topic on which we can both converse. Sagan's rebuttalis that we will share mathematics and the laws of physics, thesebeing the same for all intelligent beings regardless of localcultural and geographical variations. I show that this argumentfails even if its contentious assumptions about science andthe world are granted—that is to say, it fails on uncontentiousgrounds.

Self-perceived peer harassment in a community sample of Norwegian school children

OBJECTIVE: The experience of being harassed is associated with various forms of maladjustment. This study examined the prevalence of three domains of harassment, and their associations with emotional and behavioral problems. METHOD: A total of 4130 young people in 6th through 10th grade in 66 primary and secondary schools in Norway completed questionnaires on self-perceived harassment and emotional and behavioral problems. RESULTS: The structural psychometric properties of the scales of harassment showed an acceptable fit to the data. Boys reported more harassment on all items and domains than girls across grades. Strong associations between self-perceived harassment and psychiatric impact and behavioral and emotional problems, especially peer problems and conduct disorder, were revealed. DISCUSSION: The study adds to the understanding of the concept of harassment and its correlations with emotional and behavioral problems. The study underscores the importance of conducting routine screening in school as an important basis for the subsequent improvement in children's relationships.     

Museums as avenues of learning for children: a decade of research

In this review, we focus on the museum activities and strategies that encourage and support children’s learning. In order to provide insight into what is known about children’s learning in museums, we examined study content, methodology and the resultant knowledge from the last decade of research. Because interactivity is increasingly seen as essential in children’s learning experiences in a museum context, we developed a framework that distinguishes between three main interactivity types for facilitating strategies and activities in children’s learning: child–adults/peers; child–technology and child–environment. We identify the most promising strategies and activities for boosting children’s learning as situated in overlapping areas of these interactivity types. Specifically, we identify scaffolding as a key to enhanced museum learning. Our review concludes by highlighting research challenges from the last decade and recommendations for practice and future research on how to design, evaluate and guide theoretically-grounded educational programs for children in museums.     

Do Mothers or Children Lead the Dance? Disentangling Individual and Influence Effects During Conflict

Are mother–child conflict discussions shaped by time-varying, reciprocal influences, even after accounting for stable contributions from each individual? Mothers were filmed discussing a conflict for 5 min, separately with their younger (ages 5–9, N = 217) and older (ages 7–13, N = 220) children. Each person’s conflict constructiveness was coded in 20-s intervals and data were analyzed using dynamic structural equation modeling, which separates individual and influence effects. Children influenced their mothers’ behavior under certain conditions, with evidence for developmental differences in the magnitude and direction of influence, whereas mothers did not influence their children under any circumstance. Results are discussed in the context of child effects on parent behavior and changes in parenting across middle childhood.     

THE EIGHTEEN‐MONTH EXPERIENCE OF THE NATIONAL EVALUATION COMMITTEE IN FRANCE

This article describes the origins of and the rationale for the creation of the French National Evaluation Committee, the niche which it fills within the context of French higher education, its make‐up, details of its first year of activity, its typical procedures for the evaluation of. a given institution and, in general terms, its evaluation criteria. An annex lists the current members of the Committee, the President of which is Laurent Schwartz, a member of the French Academy of Sciences.
