Interprétation tribologique de la perception tactile de surfaces texturées

2018

International audience; Ces dernières années, l’industrie a porté un intérêt grandissant à la qualité sensorielle de leurs produits, et notamment à la sensation tactile qu’ils procurent. Selon Hollins et al, l’ensemble des surfaces matérielles peuvent être définies selon quatre dimensions psycho-perceptives tactiles : « glissant/collant », « lisse/rugueux », « chaud/froid » et « dur/mou » [1]. La texturation de surface est un moyen de parvenir à la réalisation d’une variété de surfaces appartenant, du point de vue de la perception tactile, aux deux premières dimensions susnommées. Néanmoins, les liens entre les paramètres topographiques des textures et la sensation ressentie lors du toucher…

Pain experience and social support of endometriosis patients during the COVID-19 pandemic in Germany – results of a web-based cross-sectional survey

2021

Background Endometriosis is a chronic pain condition in premenopausal women. Pain is mainly characterized by pain intensity and may induce disability in all areas of daily life. Nevertheless, pain is influenced by emotional and social factors as well. Social distancing measures or quarantine, as reaction to rapidly rising infections with the COVID-19 virus due to the SARS-CoV-2 pandemic, were implemented across Europe to prevent the spread of the virus and social distancing measures were imposed by the German government by beginning of March 2020 with initiation of the lockdown by the end of March 2020. The objective of this study was to assess, how social distancing measures during the lo…

Impact of COVID-19 pandemic on mobility in ten countries and associated perceived risk for all transport modes.

2021

The restrictive measures implemented in response to the COVID-19 pandemic have triggered sudden massive changes to travel behaviors of people all around the world. This study examines the individual mobility patterns for all transport modes (walk, bicycle, motorcycle, car driven alone, car driven in company, bus, subway, tram, train, airplane) before and during the restrictions adopted in ten countries on six continents: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. This cross-country study also aims at understanding the predictors of protective behaviors related to the transport sector and COVID-19. Findings hinge upon an online survey con…

Effects of different lower-limb sensory stimulation strategies on postural regulation-a Systematic review and metaanalysis

2017

Systematic reviews of balance control have tended to only focus on the effects of single lower-limb stimulation strategies, and a current limitation is the lack of comparison between different relevant stimulation strategies. The aim of this systematic review and meta-analysis was to examine evidence of effects of different lower-limb sensory stimulation strategies on postural regulation and stability. Moderate- to high-pooled effect sizes (Unbiased (Hedges' g) standardized mean differences (SMD) = 0.31-0.66) were observed with the addition of noise in a Stochastic Resonance Stimulation Strategy (SRSS), in three populations (i.e., healthy young adults, older adults, and individuals with low…

Interaction features for prediction of perceptual segmentation:Effects of musicianship and experimental task

2016

As music unfolds in time, structure is recognised and understood by listeners, regardless of their level of musical expertise. A number of studies have found spectral and tonal changes to quite successfully model boundaries between structural sections. However, the effects of musical expertise and experimental task on computational modelling of structure are not yet well understood. These issues need to be addressed to better understand how listeners perceive the structure of music and to improve automatic segmentation algorithms. In this study, computational prediction of segmentation by listeners was investigated for six musical stimuli via a real-time task and an annotation (non real-tim…

Learning and Synchronising Dance Movements in South African Songs – Cross-cultural Motion-capture Study

2011

Music and dance are human universals. Understanding the communicative nature and the interpersonal dynamics of making music and dancing has a wide area of applications from academic to artistic, educational and therapeutic uses. Cross-cultural and embodied cognitive approaches are important, as they ensure a view across a spectrum of cultural practices and allow us to explore which aspects of cognitive performance are learned and how. In this study, our aims were to use a case study to investigate possible cross-cultural differences in movement, especially corporeal representation of beat and metre; to study group entrainment and factors contributing to synchronisation accuracy. From earli…

Practitioners’ conceptions of ethical practice in social networking in career services

2018

AbstractThis article reports on a phenomenographic investigation into practitioners’ conceptions of ethical practice in social networking in career services. The results show that ethical practice was conceived as stemming from: (1) an information orientation, (2) a networking orientation, (3) an educational orientation, and (4) a collaborative orientation. Differences appeared along six dimensions including: approach, activities, level of usage, perception, strategy and ethical principles. The findings give us a more profound understanding of critical aspects that may have an important role in relation to further developments and the successful implementation of existing and emerging techn…

Now you see me, now you don’t: applying automated content analysis to track migrant women’s salience in German news

2020

Reading media headlines and articles about migration, one quickly gets the impression that the media discourse is focussed on migrant men. To investigate to what extend this perception actually hol...

<title>The perception of isoluminant coloured stimuli of amblyopic eye and defocused eye</title>

2008

In routine eye examination the visual acuity usually is determined using standard charts with black letters on a white background, however contrast and colour are important characteristics of visual perception. The purpose of research was to study the perception of isoluminant coloured stimuli in the cases of true and simulated amlyopia. We estimated difference in visual acuity with isoluminant coloured stimuli comparing to that for high contrast black-white stimuli for true amblyopia and simulated amblyopia. Tests were generated on computer screen. Visual acuity was detected using different charts in two ways: standard achromatic stimuli (black symbols on a white background) and isoluminan…
