Disseny i validació d'un qüestionari per mesurar les actituds necessàries per tenir cura de la salut de les persones
2022
Actualment són moltes les veus que es posicionen per fer evident que la preparació per poder tenir cura de les persones no sols ha de ser tècnica sinó també ètica (Bellver Capella, 2014), (Domingo Moratalla, 2013), (Arroyo Gordo M. P., Cortina Orts, Torralba Madrid, & Zugasti Cabrillo, 1997), (Noddings, 2003), perquè aquesta acció és una acció transcendent (Watson, 2011). Les cures són el fenomen fonamental de l’existir (Heidegger, 1999) i abasten no sols el camp d’allò físic sinó també allò moral, construir-se; créixer i madurar (Foucault, 1990). La formació de les infermeres i infermers com a responsables de la cura de la salut de les persones, haurà de permetre no sols acumular coneixeme…
Stavo per scivolare, ho pensato a Wittgenstein!. Etnopragmatica di un concetto
2016
In questo saggio, esploro la porta semiotica e pragmatica di un’azione (‘scivolare’), comunemente appartenente all’ambito del quotidiano, per mostrarne invece la valenza teorica e metateorica oltre che d’ordine pratico. Le domande che mi pongo sono le seguenti: come si può riflettere sul quotidiano in chiave antropologica? Come analizzare il senso di un concetto soltanto in apparenza d’uso comune? Come eludere la metafisica radicata nelle nostre proprie analisi? Per rispondere a queste domande, mi sono avvalso del concetto di gioco linguistico formulato da Wittgenstein rinviando allo ‘scivolare’ in opposizione all’‘attrito’ e, infine, al concetto stesso di ‘gioco linguistico’. Ho dunque mes…

Therapeutic Benefits of Music-Based Synchronous Finger Tapping In Parkinson’s Disease – an fNIRS Study Protocol for Randomized Controlled Trial in Da…
2020
Abstract Background: Music therapy improves neuronal activity and connectivity of healthy persons and patients with clinical symptoms of neurological diseases like Parkinson’s disease, Alzheimer’s Disease, and Major Depression. Despite the plethora of publications that have reported the positive effects of music interventions, little is known about how music improves neuronal activity and connectivity in afflicted patients.Methods: For patients suffering from Parkinson’s disease (PD), we propose a daily 25-minute music-based synchronous finger tapping (SFT) intervention for 8-weeks. Eligible participants with PD are split into two groups: an intervention group and a control arm. In addition…
Less Effort, Better Results: How Does Music Act on Prefrontal Cortex in Older Adults during Verbal Encoding? An fNIRS Study
2014
Several neuroimaging studies of cognitive aging revealed deficits in episodic memory abilities as a result of prefrontal cortex (PFC) limitations. Improving episodic memory performance despite PFC deficits is thus a critical issue in aging research. Listening to music stimulates cognitive performance in several non-purely musical activities (e.g., language and memory). Thus, music could represent a rich and helpful source during verbal encoding and therefore help subsequent retrieval. Furthermore, such benefit could be reflected in less demand of PFC, which is known to be crucial for encoding processes. This study aimed to investigate whether music may improve episodic memory in older adult…
Education in a crisis. Italy within southern Europe: Trends and the way forward
2016
El artículo analiza la reacción peculiar del sistema educativo italiano a la reciente crisis, en comparación con países dotados de un «modelo de bienestar Mediterráneo», como Grecia, Portugal y España. Analizando los principales indicadores estadísticos nacionales de los sistemas educativos –acceso a la educación, éxito escolar, equidad e inclusión de alumnos inmigrantes– se ha profundizado en las dificultades, pero también en la resiliencia del sistema italiano de educación. El análisis permite concluir que las prioridades en términos de reforma son: completar el proceso de autonomía escolar, completar el plan de digitalización, dotando todas las escuelas de TICs actualizadas, cambiar la j…
Brain Monitoring Via an Innovative CW-FNIRS System
2015
Functional Near InfraRed Spectroscopy (fNIRS) is an imaging technique mainly devoted to human brain monitoring. It is used as a non-invasive technique, in medical field, in order to measure the oxygen concentration of blood. This because the relatively good transparency of biological materials in the near infrared allows sufficient photon transmission through tissues. Within the so-called fNIRS range (650-900 nm), the main absorbers are blood chromophores, in particular the oxygenated and deoxygenated haemoglobin (HbO2 and Hb, respectively). When two or more wavelengths are used, changes of such chromophores can be computed by employing the modified Beer-Lambert law, thus providing importan…
Design and realization of a portable continuous wave fNIRS
2015
A design and implementation of a portable functional Near InfraRed Spectroscopy embedded system prototype is described. In this theoretical and experimental work, we present an embedded system hosting 64 LED sources and 128 Silicon PhotoMultiplier detectors (SiPM). The elementary part of the structure is a flexible probe “leaf” consisting of 16 SiPMs, 4 couples of LEDs, each operating at two wavelengths, and a temperature sensor. The hardware system is based on an ARM main microcontroller that allows to perform both the switching time of LEDs and the acquisition of the SiPM outputs. The performed preliminary experimental tests achieved very promising results, thus demonstrating the effectiv…
Continuous Wave fNIRS with Silicon Photomultiplier
2015
This work is focused on the development of a Continuous Wave (CW) NIRS integrated system with multi-wavelength LED sources between 700 and 950 nm and a Silicon Photomultiplier detector (SiPM) developed by STMicroelectronics. The Signal Noise Rate (SNR), measured placing the LEDs and an SiPM in a direct contact with the surface of a plastic phantom mimicking a real human head, results higher than the calculated minimum, required to detect small variation in the HbO2 and HHb concentration, till a source detector separation (SDS) of 6 cm.
Spotlight on fundus autofluorescence
2018
Ana M Calvo-Maroto,1 Alejandro Cerviño2 1Department of Ophthalmology, Clínica Universidad de Navarra, University of Navarra, Madrid, Spain; 2Optometry Research Group, Department of Optics and Optometry and Vision Sciences, University of Valencia, Valencia, Spain Abstract: Fundus autofluorescence (FAF) imaging is based on the fluorescence from ocular endogenous fluorophores located in the retinal pigment epithelium and choroid, mainly lipofuscin and melanin. It is a noninvasive technique that provides information about the spatial distribution of lipofuscin/melanin and retinal pigment epithelium health status. An overview about the fluorophores responsible for FAF imaging and t…
