La prospettiva neurodidattica nella valutazione delle competenze metodologicodidattiche dell’insegnante
No full textThe boost provided by Brain-based studies is a source of inspiration and change for teaching and for teacher training (Gola, 2022). Reflection and self-reflection on the practices and methodological-didactic choices introduced in the classroom deserve careful analysis and a systematic and continuous assessment of educational procedures, methods and principles aimed at promoting the educational success of each learner (Albanese, Compagno, 2022).
This contribution is placed in this perspective, which moves from a research project, already started in 2021, at the SPPEFF Department of the University of Palermo, and aimed at defining strategies and tools for the evaluation of neuroeducation activities for the development of some methodological-didactic skills of the first cycle schoolteacher, with respect to five areas of neuroeducation interest: transversal, cognitive, socio-emotional, expressive, and motor
CAUSALITY AND LOCALIZATION OPERATORS
No full textThe evolution of the expectation values of one- and two-point scalar field operators and of positive localization operators generated by an instantaneous point-source is non-local. Non-locality is attributed either to zero-point vacuum fluctuations, or to non-local operations or to the microcausality principle being not satisfied
Localization in a QFT model
No full textLocalization properties of a QFT model, consisting of a quantum scalar field interacting linearly with a classical localized source, are investigated using various approaches present in the literature. We evaluate, to any order of the field–matter coupling constant, the time evolution of average values of one-point localization observables and scalar product between the quantum field state of the evolving system and localized states. We show that the appearance of nonlocality can be connected to nonlocal properties of localized states used or to the fact that localization operators do not satisfy the microcausality principle and therefore does not imply the violation of causalit
Non locality and causal evolution in QFT
No full textNon-locality appearing in QFT during the free evolution of localized field states and in the Feynman propagator function is analysed. It is shown to be connected to the initial non-local properties present at the level of quantum states and it does not imply a violation of Einstein's causality. Then a simple QFT system with interaction, consisting of a classical source coupled linearly to a quantum scalar field is investigated and is exactly solved. The expression for the time evolution of the state describing the system is given. The expectation value of any arbitrary 'good' local observable, expressed as a function of the field operator and its space and time derivatives, is obtained explicitly at all orders in the field-matter coupling constant. These expectation values have a source-dependent part that is shown to be always causally retarded, while the non-local contributions are source independent and related to the non-local properties of zero-point vacuum fluctuation
Nonlocal quantum-field correlations and detection processes in quantum-field theory
No full textQuantum detection processes in quantum field theory (QFT) must play a key role in the description of quantum-field correlations, such as the appearance of entanglement, and of causal effects. We consider the detection in the case of a simple QFT model with a suitable interaction to exact treatment, consisting of a quantum scalar field coupled linearly to a classical scalar source. We then evaluate the response function to the field quanta of two-level pointlike quantum model detectors, and analyze the effects of the approximation adopted in standard detection theory. We show that the use of the RWA, which characterizes the Glauber detection model, leads in the detector response to nonlocal terms corresponding to an instantaneously spreading of source effects over the whole space. Other detector models, obtained with nonstandard or no application of RWA, give instead local responses to field quanta, apart from source-independent vacuum contribution linked to preexisting correlations of zero-point field

Il Compagno di Fisiologia dell'Esercizio Fisico e dello Sport
No full textAbstract
Il volume Il compagno di fisiologia è un testo di supporto allo studio della fisiologia umana, pensato per studenti dei corsi di laurea in ambito delle Scienze delle Attività Motorie e Sportive. Il libro affronta in modo sistematico i principali meccanismi funzionali dei sistemi e degli apparati dell’organismo umano, con particolare attenzione ai processi di regolazione e integrazione fisiologica. L’impostazione didattica privilegia un linguaggio chiaro e accessibile, supportato da schemi, esempi e richiami concettuali utili alla comprensione e al ripasso dei contenuti fondamentali. Il volume si propone come strumento di accompagnamento allo studio dei manuali istituzionali di fisiologia, facilitando l’apprendimento e la preparazione agli esami universitari. La collaboratrice ha contribuito alla stesura e alla revisione di specifiche sezioni del testo, apportando competenze scientifiche e didattiche nell’ambito della fisiologia umana
