Progettare interventi didattici personalizzati: implicazioni per la formazione dei futuri insegnanti
2020
L’articolo riporta i risultati di un’indagine sul terzo anno di tirocinio nel corso di laurea magistrale (LM 85-bis) in Scienze della Formazione Primaria dell’Università degli Studi di Palermo nell’anno accademico 2019-2020. È stato chiesto ai 269 studenti, che avevano svolto nei mesi precedenti 50 ore di tirocinio in classe, di descrivere le loro progettazion didattiche seguendo una guida, appositamente costruita, che li aiutasse anche a svolgere una riflessione metacognitiva sulla didattica personalizzata; inoltre la capacità decisionale degli studenti, valutata con il test QTD, è stata messa in relazione con la loro capacità di progettare in una scuola inclusiva. Al fine di preparare il …
Metālu oksīdu izejas darba mērījumi izmantojot fotoelektronu emisijas iznākuma spektroskopijas metodi
2022
Darbā tika pētīti caurspīdīgi, elektrovadoši metālu oksīdi (ITO un FTO) ar fotoelektronu emisijas iznākuma spektroskopijas metodi. Veicot eksperimentu vairākas reizes pēc kārtas, tika novērota fotoelektronu emisijas spektra pārbīde. Tika mainīti dažādi mērījumu apstākļi, piemēram, paraugi tika sildīti, noturēti vakuumā noteiktu laika posmu, un tika veikta paraugu virsmas attīrīšana ar mērķi novērst fotoemisijas spektra pārbīdes. Darbā tika veikti fotoelektronu emisijas mērījumi gaisā, kas ļāva atbrīvoties no fotoelektronu emisijas spektra pārbīdes un iegūt atkārtojamus rezultātus FTO paraugam. Mērījumi gaisā tika veikti arī organiskajiem savienojumiem P3HT un PBDB-T, lai pārliecinātos par m…

Single Event Transients and Pulse Quenching Effects in Bandgap Reference Topologies for Space Applications
2016
An architectural performance comparison of bandgap voltage reference variants, designed in a $0.18~\mu \text {m}$ CMOS process, is performed with respect to single event transients. These are commonly induced in microelectronics in the space radiation environment. Heavy ion tests (Silicon, Krypton, Xenon) are used to explore the analog single-event transients and have revealed pulse quenching mechanisms in analogue circuits. The different topologies are compared, in terms of cross-section, pulse duration and pulse amplitude. The measured results, and the explanations behind the findings, reveal important guidelines for designing analog integrated circuits, which are intended for space appli…
Programa de intervención para foavorecer la motivación hacia la lectura en el alumnado de educación primaria con un alto índice de absentismo escolar…
2015
Se describe un programa de intervención para estimular el desarrollo de la lectoescritura de una alumna de etnia gitana, de 13 años de edad, escolarizada en 6º de primaria, sin autonomía lectoescritora y con un alto índice de absentismo escolar; y que, por su origen social o cultural, no siente la necesidad de aprender a leer y a escribir. El programa se desarrolló en el aula de Pedagogía Terapéutica durante el segundo cuatrimestre del curso 2013-14. A partir del conocimiento de sus circunstancias específicas y personales, se adaptó la metodología, las actividades y los materiales de acuerdo con sus intereses, para crear necesidades reales cuya satisfacción dependa del aprendizaje de la lec…
Enhancing Light Emission in Interface Engineered Spin-OLEDs through Spin-Polarized Injection at High Voltages
2019
The quest for a spin-polarized organic light-emitting diode (spin-OLED) is a common goal in the emerging fields of molecular electronics and spintronics. In this device, two ferromagnetic (FM) electrodes are used to enhance the electroluminescence intensity of the OLED through a magnetic control of the spin polarization of the injected carriers. The major difficulty is that the driving voltage of an OLED device exceeds a few volts, while spin injection in organic materials is only efficient at low voltages. The fabrication of a spin-OLED that uses a conjugated polymer as bipolar spin collector layer and ferromagnetic electrodes is reported here. Through a careful engineering of the organic/…
Aportaciones al conocimiento de los mosquitos (Diptera, Culicidae) de alta montaña presentes en la Península Ibérica
2009
Several larval samplings of mosquitoes (Diptera, Culicidae) in different mountainous regions of the peninsular Spain were carried out. A total of 2796 specimens belonging to 18 species were collected, nevertheless the 72.5 % of these finds includes only three of them (Cx. hortensis hortensis, Cx. pipiens and Cs. longiareolata). The adaptation capacity to a varied typology of water bodies together with the marked multivoltinism that characterizes their biotic cycles are postulated as two of the principal reasons that explain their abundances. The altitudinal distribution as well as some information about the bioecology of all the species captured are also exposed.
Proprioceptive response strength in the primary sensorimotor cortex is invariant to the range of finger movement
2023
Available online 13 February 2023 Proprioception is the sense of body position and movement that relies on afference from the proprioceptors in muscles and joints. Proprioceptive responses in the primary sensorimotor (SM1) cortex can be elicited by stim- ulating the proprioceptors using evoked (passive) limb movements. In magnetoencephalography (MEG), propri- oceptive processing can be quantified by recording the movement evoked fields (MEFs) and movement-induced beta power modulations or by computing corticokinematic coherence (CKC) between the limb kinematics and cortical activity. We examined whether cortical proprioceptive processing quantified with MEF peak strength, relative beta supp…
Plantar pressure distribution analysis in normal weight young women and men with normal and claw feet: a cross-sectional study
2005
We analyzed the plantar support in 72 normal-weight young voluntaries (46 women, 26 men), by a baropodometric platform. We considered subjects with claw foot (CFS) and subjects with normal foot (NFS). We found a significant reduction of total plantar support surface in the CFS (P < 0.0001 for women, P < 0.001 for men), due to the reduction of the forefoot and rear foot areas of both plantar imprints. Indeed, CFS of both sexes exhibited higher values of both plantar pressure and peak pressure, compared to the NFS. Moreover, the load per units of plantar surface increased in CFS compared to the NFS. In conclusion, the reduction of plantar support surfaces in CFS of both sexes was associated t…
CMC is more than a measure of corticospinal tract integrity in acute stroke patients
2021
In healthy subjects, motor cortex activity and electromyographic (EMG) signals from contracting contralateral muscle show coherence in the beta (15-30 Hz) range. Corticomuscular coherence (CMC) is considered a sign of functional coupling between muscle and brain. Based on prior studies, CMC is altered in stroke, but functional significance of this finding has remained unclear. Here, we examined CMC in acute stroke patients and correlated the results with clinical outcome measures and corticospinal tract (CST) integrity estimated with diffusion tensor imaging (DTI). During isometric contraction of the extensor carpi radialis muscle, EMG and magnetoencephalographic oscillatory signals were re…
