Brand social representations: strategic perspectives for a fitness club
2009
International audience; The aim of this study was to identify an accurate tool to enable fitness club managers to discover those opinions or stereotypes which represent obstacles to joining their organisations. Starting with brand image, the analysis then considered social representations as relevant constructs for apprehending these opinions or prejudices. The use of a word association task and the model of basic cognitive schemes (Rouquette, 1990; 1994) provided access to the salient elements of the social representations of a particular sport brand and the way they are structured. The procedure combining these two stages represented a diagnostic tool for identifying the attractive and un…
Il ruolo della corteccia prefrontale dorsolaterale nella memoria di riconoscimento: uso dellla Stimolazione Magnetica Transcranica per il trattamento…
Il ruolo della corteccia prefrontale dorsolaterale (DLPFC) in compiti di memoria è stato largamente documentato. Una questione ancora molto dibattuta è il grado di lateralizzazione anatomica-funzionale dei processi di controllo esecutivo della DLPFC coinvolti nella memoria di riconoscimento. Il lavoro di tesi indaga le connessioni tra DLPFC e ippocampo mediante l’applicazione di tecniche di neuromodulazione dell’eccitabilità della DLPFC che consentano di accrescere l’attività ippocampale durante compiti di memoria di riconoscimento. I primi tre studi valutano gli effetti inibitori ed eccitatori della rTMS applicata alla DLPFC sulla performance in compiti di memoria di riconoscimento, in div…
Auditory cortical and hippocampal-system mismatch responses to duration deviants in urethane-anesthetized rats
2013
Any change in the invariant aspects of the auditory environment is of potential importance. The human brain preattentively or automatically detects such changes. The mismatch negativity (MMN) of event-related potentials (ERPs) reflects this initial stage of auditory change detection. The origin of MMN is held to be cortical. The hippocampus is associated with a later generated P3a of ERPs reflecting involuntarily attention switches towards auditory changes that are high in magnitude. The evidence for this cortico-hippocampal dichotomy is scarce, however. To shed further light on this issue, auditory cortical and hippocampal-system (CA1, dentate gyrus, subiculum) local-field potentials were …
Clinicopathological analysis of oral mucous autoimmune disease : a 27-year study
2008
Made available in DSpace on 2022-04-28T20:39:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-02-01 Objectives: The aim of the present study was to analyze the main clinical and histopathological features of autoimmune diseases with oral manifestations such as oral lichen planus (OLP); mucous membrane pemphigoid (MMP); pemphigus vulgaris (PV) and erythema multiforme (EM). Study design: Retrospective review of 5770 files from the Oral Pathology Laboratory of São José dos Campos Dental School, São Paulo State University (UNESP) comprising a 27-year period from 1974 to 2000. Results: The cases accounted for 64 (1.10%) of 5770 anatomopathological examinations performed over the study p…
Storie di famiglie e memoria storica: l'Archivio Boncompagni Ludovisi
2012
Ripercorrendo brevemente la storia delle famiglie Boncompagni, Ludovisi e Gesualdo, l’Autore intende mostrare come le modalità di conservazione delle fonti condizionino la memoria storica; in particolare, il processo di selezione demografica ha portato ad una collocazione subalterna della documentazione relativa alle famiglie estinte, sanzionando il primato delle famiglie sopravvissute nella memoria storica e, quindi, restituendo una realtà storica deformata.
Comportement en fatigue des composites en lin/époxy
2011
International audience; Le travail présenté s'intéresse à la caractérisation des propriétés mécaniques quasi-statiques et en fatigue d'un composite stratifié en lin/époxy. Les éprouvettes fabriquées par thermocompression ont des séquences d'empilement de 0/90° et ±45° pour les essais de traction uniaxiale et cisaillement plan respectivement. Les essais quasi-statiques révèlent une variabilité des propriétés mécaniques de l'ordre de 10%. Les essais de fatigue en traction et en cisaillement plan ont été réalisés pour des niveaux de contraintes compris entre 40 et 80% des valeurs ultimes du composite (US). L'étude des boucles d'hystérésis a mis en évidence une plastification plus importante en…
Memoria Autobiográfica y Atención. Perspectiva Cognitiva y Experimental.
2017
RESUMEN TESIS Título: Memoria Autobiográfica y Atención. Una perspectiva cognitiva y experimental. Doctoranda: Ana Isabel Agustí López Director de tesis: Juan Carlos Meléndez Moral Este trabajo plantea dos cuestiones u objetivos generales, en primer lugar se pretende comprobar si al estudiar la memoria autobiográfica (MA) existen diferencias entre jóvenes y adultos mayores no solamente en relación al tipo de memoria (episódica y semántica) sino también en relación al componente emocional asociado a los recuerdos y la distribución temporal del recuerdo (infancia/ adolescencia, bump de reminiscencia y recuerdos recientes). En segundo lugar, se pretende estudiar la atención mediante tareas de …
