Micro-Displacement Sensor Based on a Hollow-Core Photonic Crystal Fiber

Abstract: A sensing head based on a hollow-core photonic crystal fiber for in-reflection measurement of micro-displacements is presented. The sensing structure takes advantage of the multimodal behavior of a short segment of hollow-core photonic crystal fiber in-reflection, being spliced to a single mode fiber at its other end. A modal interferometer is obtained when the sensing head is close to a mirror, through which displacement is measured.

IncluCity: using contextual cues to raise awareness on environmental accessibility

Abstract: Awareness campaigns aiming to highlight the accessibility challenges affecting people with disabilities face an important challenge. They often describe the environmental features that pose accessibility barriers out of context, and as a result public cannot relate to the problems at hand. In this paper we demonstrate that contextual cues can enhance people's perception and understanding of accessibility. We describe a two-week study where our participants submitted reports of inaccessible spots all over the city through a web application. Using a 2x2 factorial design we contrast the impact of two types of contextual cues, visual cues (i.e., displaying a picture of the inaccessible spot) and location cues (i.e., ability to zoom-in the exact location). We measure participants' perceptions of accessibility and how they are challenged to consider their own limitations and barriers that may also affect themselves in certain circumstances. Our results suggest that visual cues led to a bigger sense of urgency while also improving participants' attitude towards disability.

Gross motor coordination and weight status of Portuguese children aged 6-14 years.

Abstract: Objectives To construct age- and gender-specific percentiles for gross motor coordination (MC) tests and to explore differences in gross MC in normal-weight, overweight and obese children. Methods Data are from the “Healthy Growth of Madeira Study,” a cross-sectional study carried out in children, aged 6–14 years. All 1,276 participants, 619 boys and 657 girls, were assessed for gross MC (Korperkoordinations Test fur Kinder, KTK), anthropometry (height and body mass), physical activity (Baecke questionnaire) and socioeconomic status (SES). Centile curves for gross MC were obtained for boys and girls separately using generalized additive models for location, scale and shape. Results A significant main effect for age was found in walking backwards and moving sideways. Boys performed significantly better than girls on moving sideways. At the upper limit of the distributions, interindividual variability was higher in hopping on one leg (girls) and jumping and moving sideways (boys and girls). One-way ANCOVA, controlling for age, physical activity and SES, indicated that normal-weight children scored significantly better than their obese peers in all gross MC tests. Overweight boys and girls also scored significantly better than their obese colleagues in some MC tests. Conclusions These centile curves can be used as reference data in Portuguese children and youth, aged 6–14 years. Being overweight or obese was a major limitation in MC tests and, therefore, of the children's health- and performance-related physical fitness. Am. J. Hum.
