The Test–Retest Repeatability of a Rhythm Coordination Test Procedure in 4- to 6-Year-Old Children : A Pilot Study
2020
Moving to music combines the ability of rhythm and coordination. In relation to the musical and motor development of children, sensorimotor synchronization requires the ability to perceive and perform a steady beat. The present pilot study aimed to investigate the test–retest repeatability of a rhythm coordination test procedure in order to pilot the procedure for children. Test–retest repeatability reflects the variation in measurements taken by the rhythm coordination test on the same participant under the same conditions. Ten children (mean age 5.5 years, standard deviation (SD) 0.6) participated in the tests. The test performance was evaluated in points from 0 to 8, separately at a slow…
Mismatch negativity (MMN) in freely-moving rats with several experimental controls.
2014
Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MMN. One of the major concerns for animal models of MMN is whether the rodent brain is capable of producing a human-like MMN, which is not a consequence of neural adaptation to repetitive stimuli. We therefore tested several methods that have been used to control for adaptation and differential exogenou…
Might as well jump: Sound affects muscle activation in skateboarding
2014
The aim of the study is to reveal the role of sound in action anticipation and performance, and to test whether the level of precision in action planning and execution is related to the level of sensorimotor skills and experience that listeners possess about a specific action. Individuals ranging from 18 to 75 years of age - some of them without any skills in skateboarding and others experts in this sport - were compared in their ability to anticipate and simulate a skateboarding jump by listening to the sound it produces. Only skaters were able to modulate the forces underfoot and to apply muscle synergies that closely resembled the ones that a skater would use if actually jumping on a ska…
Aprendiendo con todos los sentidos en la clase EFE
2016
En esta experiencia práctica queremos compartir nuestra propuesta para trabajar diferentes aspectos del mundo de los negocios desde un enfoque holístico que apele a la emoción y al uso de los sentidos y que respete los diferentes estilos de aprendizaje. Nuestro objetivo más importante es ofrecer al estudiantado la oportunidad de vivir, practicar y procesar nuevos conocimientos relacionándolos con sus experiencias y conocimientos previos. Por otra parte, aspiramos también a que nuestros estudiantes reflexionen en este proceso sobre su propio aprendizaje y la forma en la que les resulta más fácil acceder a la nueva información y hacerla memorable. Nuestra experiencia educativa, que tiene por…
Strategies for Improving Optimal Positioning of Quality Sensors in Urban Drainage Systems for Non-Conservative Contaminants
2021
In the urban drainage sector, the problem of polluting discharges in sewers may act on the proper functioning of the sewer system, on the wastewater treatment plant reliability and on the receiving water body preservation. Therefore, the implementation of a chemical monitoring network is necessary to promptly detect and contain the event of contamination. Sensor location is usually an optimization exercise that is based on probabilistic or black-box methods and their efficiency is usually dependent on the initial assumption made on possible eligibility of nodes to become a monitoring point. It is a common practice to establish an initial non-informative assumption by considering all network…
Wo3 and ionic liquids: A synergic pair for pollutant gas sensing and desulfurization
2020
This review deals with the notable results obtained by the synergy between ionic liquids (ILs) and WO3 in the field of pollutant gas sensing and sulfur removal pretreatment of fuels. Starting from the known characteristics of tungsten trioxide as catalytic material, many authors have proposed the use of ionic liquids in order to both direct WO3 production towards controllable nanostructures (nanorods, nanospheres, etc.) and to modify the metal oxide structure (incorporating ILs) in order to increase the gas adsorption ability and, thus, the catalytic efficiency. Moreover, ionic liquids are able to highly disperse WO3 in composites, thus enhancing the contact surface and the catalytic abilit…
Fluorescent Biosensors Based on Silicon Nanowires
2021
Nanostructures are arising as novel biosensing platforms promising to surpass current performance in terms of sensitivity, selectivity, and affordability of standard approaches. However, for several nanosensors, the material and synthesis used make the industrial transfer of such technologies complex. Silicon nanowires (NWs) are compatible with Si-based flat architecture fabrication and arise as a hopeful solution to couple their interesting physical properties and surface-to-volume ratio to an easy commercial transfer. Among all the transduction methods, fluorescent probes and sensors emerge as some of the most used approaches thanks to their easy data interpretation, measure affordability…
Fear of falling and coexisting sensory difficulties as predictors of mobility decline in older women
2012
Background. Mobility decline, the coexistence of several sensory difficulties and fear of falling (FOF) are all common concerns in older people; however, knowledge about the combined effect of FOF and coexisting sensory difficulties on mobility is lacking. Methods. Data on self-reported FOF, difficulties in hearing, vision, balance, and walking 2 km were gathered with a structured questionnaire among 434 women aged 63–76 years at baseline and after a 3-year follow-up. Logistic regression models were used for analyses. Results. Every third participant reported difficulties in walking 2 km at baseline. In cross-sectional analysis, the odds ratio for difficulties in walking 2 km was higher amo…
Effect of consumers’ origin on perceived sensory quality, liking and liking drivers: A cross-cultural study on European cheeses
2021
Abstract We aim at studying consumers’ Perceived Sensory Quality (PSQ) concept. We manipulated a priori both familiarity (contrast local vs. foreign cheeses) and quality level (contrast PDO or traditional cheeses vs. their non-PDO and/or industrial counterpart). The study was run in four European countries. Thus, eight cheeses (one PDO or traditional cheese and one non-PDO cheese from each of the four European countries) were assessed by a total of 438 consumers (from 100 to 120 consumers from each region) in terms of PSQ and liking. The cheeses were also described by a trained panel. PSQ depended on both consumers’ and cheeses’ origin. The main finding is that in the three countries with P…
