Corticokinematic coherence is stronger to regular than irregular proprioceptive stimulation of the hand
2021
Funding Information: This study was supported by the Academy of Finland “Brain changes across the life-span” profiling funding to University of Jyva€skyla€. H. Piitulainen was supported by Academy of Finland (Grants 296240, 326988, 307250, and 327288) and Jane and Aatos Erkko Foundation. Publisher Copyright: © 2021 the American Physiological Society. Proprioceptive afference can be investigated using corticokinematic coherence (CKC), which indicates coupling between limb kinematics and cortical activity. CKC has been quantified using proprioceptive stimulation (movement actuators) with fixed interstimulus interval (ISI). However, it is unclear how regularity of the stimulus sequence (jitter…
Uso de sensores de movimiento y otros recursos para mejorar la interpretación de gráficas en cinemática
2021
En este trabajo nos hemos planteado: ¿qué dificultades presenta el alumnado al interpretar gráficas de cinemática?, ¿cuáles pueden ser las causas de estas dificultades?, ¿se puede mejorar dicha destreza con la implementación de una secuencia de enseñanza aprendizaje que contemple el uso de sensores de movimiento y otros recursos? Para responder estas preguntas nos planteamos dos hipótesis. La primera afirma que el alumnado presenta dificultades interpretando gráficas de cinemática por la forma en que se enseña esta unidad didáctica, sin apenas experimentación, lo que dificulta que el alumnado relacione el movimiento real con las gráficas. La segunda hipótesis plantea que, si se diseña y se …
Is Environmental Sustainability Also “Economically Efficient”? The Case of the “SOStain” Certification for Sicilian Sparkling Wines
2022
The Italian wine industry is strongly committed to sustainability. Among the numerous sustainability certifications and programs implemented in Italy for the wine sector, SOStain is the oldest at the regional level. The SOStain Foundation promotes the voluntary application of a sustainability program, developed in 2010 in Sicily (Southern Italy). The requirements of the SOStain specifications are connected to the new CAP 2023–2027 objectives; therefore, companies preparing for the new challenges of future winemaking might be interested in joining the SOStain Foundation for greening production practices. The objective of this study was to learn producers’ and consumers’ opinions about motiva…
Deep Talk: A Dialogic Instruction Method for Enhancing the Sense of Belonging
2022
In this study, we investigate Deep Talk, which is a method used in the context of early years education in Finland. The method is based on multisensory storytelling and clear phases. The method has received positive feedback from educators and children, but no prior research has been conducted on it. This data aims to determine the significant elements of the method for the individual child and the children in a group. The data consisted of 25 narrations of educators who participated in Deep Talk training and had been serving as Deep Talk instructors. The data were analyzed using a data- and theory-driven qualitative content analysis through the dialogical process of the research team. The …
Multisensorās stratēģijas skolēnu ar speciālajām vajadzībām iesaistīšanai angļu valodas stundās pamatskolā
2015
Skolotāja pieredzes mapes autore ir angļu valodas skolotāja un speciālais pedagogs vidusskolā. Skolēnu ar speciālajām vajadzībām iekļaušana vispārizglītojošajā skolā ir izraisījusi skolotāju diskusijas par to, kā sekmēt visu skolēnu iesaistīšanos vienas stundas laikā, ņemot vērā, ka viņu spējas un vajadzības ir tik dažādas. Autore ir mēģinājusi atrast visefektīvāko veidu darbā ar skolēniem ar speciālajām vajadzībām; kā risinājums ir rasts multisensoro stratēģiju izmantošana. Lai dalītos profesionālajā pieredzē, kā noslēguma darba forma tika izvēlēta skolotāja pieredzes mape. Darba mērķis ir noskaidrot, kuras multisensorās stratēģijas sekmē skolēnu ar speciālajām vajadzībām iesaistīšanos ang…
Assessment of the tibia using ultrasonic guided waves in pubertal girls
2002
The purpose of this study was to compare low frequency ultrasonic guided wave measurements with established ultrasound and bone density measurements in terms of their ability to characterize the tibia in pubertal girls. Subjects were 12-14-year-old girls ( n=106) who were participating in a calcium and vitamin D intervention study. A prototype low frequency pulse transmission device consisting of a uniaxial scanning mechanism and low frequency transducers orientated perpendicularly to the limb was used to measure two ultrasound velocities in the tibia. The first velocity, V1, was that of the first arriving signal, similar to that measured by existing commercial tibial ultrasound devices. Th…
Use of accelerometers and gyros for hip and knee angle estimation
2013
In this paper a wearable sensor system, consisting of accelerometers and gyros, has been studied to estimate hip and knee angles. The proposed algorithm, developed in order to avoid the error accumulation due to gyroscopes drift, has been tested on angle measurement of the hip and knee of a commercial device for assisted gait. The results have shown a good accuracy of the angles estimation, also in high angle rate movement
MRI findings and evoked potentials in patients with myotonic dystrophy versus facioscapulohumeral dystrophy
1997
Evoked potentials recordings have been applied to many neurological disorders, localizing the lesions in the central nervous system (CNS) pathways. Facioscapulohumeral muscular dystrophy (FSHD) is a slowly progressive degenerative disease involving the muscles of the face and shoulders. On the contrary, myotonic distrophy (MD), the most frequent and severe myotonic disease, is caracterized by myotonia (delay of relaxation after voluntary contraction), muscular atrophy and dystrophic changes in non-muscular tissues. In the present investigation, patients with clinically and electromyographically verified FSHD and MD were examined using somatosensory evoked potentials (SEP) and brainstem aud…
Hearing loss in facioscapulohumeral dystrophy.
1986
Bilateral sloping high frequency hearing loss of 20–90 dB was found in six out of ten patients with infantile or adolescent onset FSHD. In all cases the basic defect could be traced to the cochlea. The outer hair cells of the basal turn are predominantly affected. In 20 patients with various other forms of muscular dystrophy or neuromuscular disorders with an FSH distribution, no sensorineural hearing loss was found. Myopathology of FSHD patients extended from mild to severe, often showing inflammatory infiltrates and type I fibre atrophy, without unequivocal differences between the two groups with and without hearing loss. It is concluded that cochlear dysfunction is a specific and frequen…
Molecular and Macromolecular Changes in Bottle-Aged White Wines Reflect Oxidative Evolution–Impact of Must Clarification and Bottle Closure
2018
This article is part of the Research Topic "The Chemistry of Wine Ageing" Adresse de correspondance: Institut Universitaire de la Vigne et du Vin, Dijon, France PMCID: PMC5897750; International audience; Chardonnay wines from Burgundy, obtained from musts with three levels of clarification (Low, Medium and High) during two consecutive vintages (2009 and 2010) and for two kinds of closures (screw caps and synthetic coextruded closures) were analyzed chemically and sensorially. Three bottles per turbidity level were opened in 2015 in order to assess the intensity of the reductive and/or oxidative aromas (REDOX sensory scores) by a trained sensory panel. The chemical analyses consisted in poly…
