Stress Assessment of Vestibular Endurance Training for Civil Aviation Flight Students Based on EEG
2021
AbstractObjectiveThe main goal of our study is to clarify the EEG characteristics of the stress response caused by vestibular endurance training under the real conditions.MethodsTen pilot trainees received a series of acute anti-vertigo training stimulations on the rotary ladder while recording electroencephalographic data (64 electrodes). Afterwards, the subject’s anti-vertigo ability was tested for the best performance after 1 month of training, and verifying whether it is relating to the EEG signals we collected before.Results(1) The absolute power ofαwaves in the C3 and C4 regions is same as the difference between 1 min before and 2 min after stimulation, and their activity is enhanced …

Interconceptualizing Europe and Peace : Identity Building Under the European Heritage Label
2019
AbstractThis chapter investigates how peace is used in attempts to build a collective identity for the European Union in the context of the European Heritage Label (EHL), a central instrument in the EU’s cultural heritage policy. The official EHL documents and the websites of the EHL sites are analysed using a conceptual approach that particularly focuses on the interconceptualizations between peace and Europe. The ways peace is discussed can be divided into four thematic categories: treaties, institutions, practices, and symbols related to peace. The chapter concludes that heritage related to peace is mainly discussed in a non-contradictory manner, with little space for dissonance.
Unveiling the Unexpected Reactivity of Electrophilic Diazoalkanes in [3+2] Cycloaddition Reactions within Molecular Electron Density Theory
2021
The [3+2] cycloaddition (32CA) reactions of strongly nucleophilic norbornadiene (NBD), with simplest diazoalkane (DAA) and three DAAs of increased electrophilicity, have been studied within the Molecular Electron Density Theory (MEDT) at the MPWB1K/6-311G (d,p) computational level. These pmr-type 32CA reactions follow an asynchronous one-step mechanism with activation enthalpies ranging from 17.7 to 27.9 kcal·
Intraflagellar transport protein 172 is essential for primary cilia formation and plays a vital role in patterning the mammalian brain
2008
AbstractIFT172, also known as Selective Lim-domain Binding protein (SLB), is a component of the intraflagellar transport (IFT) complex. In order to evaluate the biological role of the Ift172 gene, we generated a loss-of-function mutation in the mouse. The resulting Slb mutant embryos die between E12.5 and 13.0, and exhibit severe cranio-facial malformations, failure to close the cranial neural tube, holoprosencephaly, heart edema and extensive hemorrhages. Cilia outgrowth in cells of the neuroepithelium is initiated but the axonemes are severely truncated and do not contain visible microtubules. Morphological and molecular analyses revealed a global brain-patterning defect along the dorsal–…
Inhibitory effect of A10 dopaminergic neurons of the ventral tegmental area on the orienting response evoked by acoustic stimulation in the cat.
1998
Abstract The effect of bilateral electric stimulation of A10 dopaminergic neurons of the ventral tegmental area (80–300 μA, 20–50 Hz, 0.1–0.5 ms, 2 s duration) on latency and duration of the orienting response, evoked by acoustic stimuli (4500–8000 Hz, 2 s), was studied in the cat. A10 neuron stimulation, simultaneous with the acoustic one, was performed with threshold parameters inducing minimal behavioral signs (head searching movement, sniffing, increase in alertness). By means of a videoanalysis system, a statistically significant increase, both of latency and duration of the response, was observed. The possible role of dopamine was studied administrating sulpiride (20 mg/kg IP), a dopa…
Parental Involvement in Math Homework: Links to Children’s Performance and Motivation
2017
The present study examined the longitudinal associations between children’s perceptions of parental involvement in math homework (control and support) and their math performance and motivation (taskpersistent homework behavior and math self-concept). Children (n = 512) reported their perceptions concerning parental involvement in sixthgrade math homework. In grades 3 and 6, children completed math tests, evaluated own math self-concept, and their mothers (n = 420) evaluated task persistence during homework. The results showed that low selfconcept in math predicted increased parental control, which in turn related to low math performance, task persistence, and math selfconcept. Second, perce…
Crianza, prosocialidad y relaciones entre los pares en la adolescencia. Factores implicados en los comportamientos antisociales
2017
La adolescencia es la etapa evolutiva de transición entre la infancia y la edad adulta. Este periodo está acompañado de numerosas transformaciones fisiológicas, cognitivas y sociales, que amplían la capacidad de analizar y comprender procesos más complejos, así como las necesidades de ampliar las relaciones sociales. Desde la perspectiva de la Teoría Social Cognitiva y la Psicología Positiva conviene poner el acento en factores personales que estimulan la adaptación social. Con todo, en esta etapa, el adolescente se enfrenta a conflictos personales y sociales, fruto de las nuevas demandas y necesidades (Marina, Rodríguez y Lorente, 2015; Oliva et al., 2010; Viejo y Ortega-Ruiz, 2015). Será …
Explorer les possibles de l'écriture multimédia
2011
International audience; Dans cet article, nous posons la question d’une écriture multimédia et de ses spécificités. Le multimédia permet-il d’ouvrir des possibles pour l’écriture ? Pour comprendre et explorer ces possibles, nous mobilisons une théorie du numérique et proposons un modèle en trois niveaux de l’écriture multimédia. Nous utilisons cette approche conceptuelle pour analyser des pratiques éditoriales professionnelles à l’Institut national de l’audiovisuel (Ina).
