Observaciones sobre una reflexión heterodoxa en los Comentarii de Juan Luis Vives a la Ciudad de Dios de San Agustín
2019
The Patres ecclesiae?s works were a frequent topic of discussion at the time in which many humanists stood against the decadent medieval scholastics. That Juan Luis Vives was part of this tradition is demonstrated in his commentaries on Saint Augustine works. Despite its pedagogical function, the scholia of the Valencian author became quite subjective. In this sense, his ecdotic work or, specially, his «criticisms and censures» can be mentioned. Here, Vives strongly disapproves of the intense political and intellectual turmoil of his epoch. Thus, this article is aimed at describing those annotations in which Vives adopts such an Erasmist point of view to comment Augustine?s De Civitate Dei.…
El saber gramatical sobre los tiempos del pasado en alumnos de 4º de Secundaria Obligatoria. Las relaciones entre conceptualización y uso reflexivo e…
2011
La presente tesis doctoral se pregunta por la relación entre la conceptualización y el uso reflexivo en la enseñanza de la gramática, a partir de una intervención en aula dirigida a alumnos de 4º de ESO (15-16 años), diseñada como un estudio de evaluación a pequeña escala (Piggot y Barr, 2002), según el modelo de secuencias didácticas de gramática (Camps, 2003). Como punto de partida, se eligió un problema observado en las aulas: el predominio del perfecto simple en las narraciones escritas de los estudiantes, en contextos en que la alternancia con el pluscuamperfecto era posible (Perdió el libro que se compró/había comprado pocos días antes). Para estudiar si la reflexión sobre los tiempos…
15. Functional mapping of monaural auditory brainstem responses
2012
Background and aims: The pedunculopontine nucleus (PPN) is a new deep brain stimulation (DBS) target, thought to be particularly for useful in ameliorating gait disturbance in Parkinson’s disease. Recent evidence shows a prominent theta (4–7 Hz) rhythm in the PPN (Tsang et al., Neurology, 2010; Simon et al., J. Neurophysiol., 2010; Shimamoto et al., JNNP, 2010). Given that theta activity is modulated by vestibular signals elsewhere in the brain, e.g. hippocampus, (Shin, Synapse, 2010; Chen et al., Neuroimage, 2010), we assessed whether vestibular signals modulate PPN theta activity. Methods: We recorded local field potentials (LFPs) in three patients with implanted bilateral subthalamic nuc…
Functional brain imaging of peripheral and central vestibular disorders.
2008
This review summarizes our current knowledge of multisensory vestibular structures and their functions in humans. Most of it derives from brain activation studies with PET and fMRI conducted over the last decade. The patterns of activations and deactivations during caloric and galvanic vestibular stimulations in healthy subjects have been compared with those in patients with acute and chronic peripheral and central vestibular disorders. Major findings are the following: (1) In patients with vestibular neuritis the central vestibular system exhibits a spontaneous visual-vestibular activation–deactivation pattern similar to that described in healthy volunteers during unilateral vestibular sti…
Comparative study of the effect of gentamicin on the vestibulo-ocular and visual vestibulo-ocular reflexes in the cat.
1991
The ototoxic effect of an aminoglycoside, gentamicin, on the vestibular system was investigated in cats given daily doses of 40 mg/kg i.m. for 14 days. Periodically, measurements were made of the vestibulo-ocular reflex (VOR) and visual vestibulo-ocular reflex (ViVOR) responses induced by rotatory stimuli at various frequencies from 0.0125 Hz to 0.8 Hz. After the cessation of drug administration, a progressively declining response to VOR stimuli continued, manifested by gain (ratio of peak response to peak stimulus amplitude) and phase relationships. The ViVOR was affected only in the gain measurements. The changes in the response amplitude (gain) were greater for the VOR than for the ViVOR…
Vertigo, Masseter Paresis or Masseter Reflex Abnormality, and Impaired Caloric Response
1993
Symptoms and signs of acute peripheral-type vestibular abnormalities occasionally occur in patients with multiple sclerosis and brain-stem ischemia. Such patients may show reduced excitability of the lateral semicircular canal. From this observation, the question arises as to the location of the causative lesion.
CLINICAL AND NEUROPHYSIOLOGICAL FINDINGS IN 47 LONG-TERM SURVIVORS OF CHILDHOOD MALIGNANCIES TREATED WITH VARIOUS DOSES OF VINCRISTINE
1978
ABSTRACT 96 long-term survivors of cancer in childhood were reexamined after succesful therapy. In 49 who had not been treated with VINCRISTINE (VCR) reflex status and motor conduction velocities were normal. In contrast, 47-after treatment with VCR-had loss of deep tendon reflexes in a high rate and a prolongation of sensory CV independent of the 1 total cumulative dose of VCR, 2 application mode according to different treatment regimen, 3 time interval since the last injections of the drug, 4 age of children at onset of therapy.

Insertion professionnelle des diplômés de l'enseignement supérieur en Europe : premiers résultats de l'enquête REFLEX
2009
09014; Le projet REFLEX (The Flexible Professional in the Knowledge Society) a été conduit par un consortium d'équipes de recherche de 16 pays (15 pays européens et le Japon). Une enquête a été réalisée en 2005 auprès de 40000 personnes diplômées 5 ans auparavant dans les 16 pays. On observe qu'il existe beaucoup de convergence entre les pays européens : dans l'ensemble, les compétences produites par les systèmes éducatifs semblent bien utilisées avec quelques problèmes ponctuels : les pays du sud de l'Europe, certaines disciplines comme les lettres et les sciences humaines. Les caractéristiques des systèmes éducatifs expliquent bien souvent les écarts entre l'offre et la demande qui se tra…
