Motor imagery and cortico-spinal excitability: A review
2016
International audience; Motor imagery (MI) has received a lot of interest during the last decades as its chronic or acute use has demonstrated several effects on improving sport performances or skills. The development of neuroimagery techniques also helped further our understanding of the neural correlates underlying MI. While some authors showed that MI, motor execution and action observation activated similar motor cortical regions, transcranial magnetic stimulation (TMS) studies brought great insights on the role of the primary motor cortex and on the activation of the cortico-spinal pathway during MI. After defining MI and describing the TMS technique, a short report of MI activities on…
Pragmatics, Metaphor Studies and the Challenge of Mental Imagery
2023
Metaphor is considered a figurative use of language, a term that seems to recall the imagistic dimension characterizing this kind of utterances. Tzvetan Todorov (1967) speaks of “figure” as “visibility of speech”: as a figure, metaphor provides a kind of figurability to what is communicated. As Paul Ricoeur wrote in La métaphore vive (Ricoeur, 1975), metaphor makes “speech appear”. Precisely because of the reliance on the idea of figure, it is therefore not surprising that discussions on metaphor often refer to the role that mental images play in their comprehension. A long tradition holds that the formation of a mental image is fundamental for the comprehension of certain kinds of metaphor…
Improving Hand Hygiene Behavior Using a Novel Theory-Based Intervention During the COVID-19 Pandemic
2022
Abstract Background Promoting the adoption of personal hygiene behaviors known to reduce the transmission of COVID-19, such as avoiding touching one’s face with unwashed hands, is important for limiting the spread of infections. Purpose We aimed to test the efficacy of a theory-based intervention to promote the avoidance of touching one’s face with unwashed hands to reduce the spread of COVID-19. Methods We tested effects of an intervention employing imagery, persuasive communication, and planning techniques in two pre-registered studies adopting randomized controlled designs in samples of Australian (N = 254; Study 1) and US (N = 245; Study 2) residents. Participants were randomly assigned…
Cavezzo, the first Italian meteorite recovered by the PRISMA fireball network. Orbit, trajectory, and strewn-field
2020
ABSTRACT Two meteorite pieces have been recovered in Italy, near the town of Cavezzo (Modena), on 2020 January 4th. The associated fireball was observed on the evening of New Year’s Day 2020 by eight all-sky cameras of the PRISMA fireball network, a partner of FRIPON. The computed trajectory had an inclination angle of approximately 68° and a velocity at infinity of 12.8 km s−1. Together with the relatively low terminal height, estimated as 21.5 km, those values were indicating the significant possibility of a meteorite dropping event, as additionally confirmed by the non-zero residual total mass. The strewn-field was computed taking into account the presence of two bright light flashes, re…
Pleasant Musical Imagery : Eliciting Cherished Music in the Second Person
2019
This article introduces the notion of pleasant musical imagery (PMI) for denoting everyday phenomena where people want to cherish music ‘‘in their heads.’’ This account differs from current paradigms for studying musical imagery in that it is not based a priori on (in)voluntariness of the experience. An empirical investigation of the structure and experiential content in 50 persons’ experiences of PMI applied the elicitation interview method. Peer judgments of the interviews helped to bridge a phenomenological investigation of particular experiences with systematic between-subjects analysis. Both structural features of the imagery (e.g., Looseness of structure or Looping) and content featur…
ON-LINE CONSTRUCTION OF A SMALL AUTOMATON FOR A FINITE SET OF WORDS
2012
In this paper we describe a "light" algorithm for the on-line construction of a small automaton recognising a finite set of words. The algorithm runs in linear time. We carried out good experimental results on real dictionaries, on biological sequences and on the sets of suffixes (resp. factors) of a set of words that shows how our automaton is near to the minimal one. For the suffixes of a text, we propose a modified construction that leads to an even smaller automaton. We moreover construct linear algorithms for the insertion and deletion of a word in a finite set, directly from the constructed automaton.
Estereotipos asociados al cuerpo humano: análisis de aplicaciones móviles usadas en la educación físico-deportiva
2022
Institutions and educators are massively and uncritically integrating digital curricular materials in their teaching praxis. This article aims to uncover whether health and fitness APP images convey or legitimize stereotypes linked to bodies, focusing on gender, race, somatotype and physical activity practice. We also analyse whether these apps are adequate for the recommended age or whether they are designed by physical education professionals. For that purpose, we designed a descriptive, comparative study based on content analysis on a sample of 373 images from 128 apps selected through a PRISMA review and a pilot test. Our results report that bodies reproduce a series of stereotypes: of …
An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety
2017
In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…
