Índices nacionales de satisfacción del consumidor: Una propuesta de revisión de la literatura

2011

Durante las últimas décadas, gran cantidad de académicos del ámbito del marketing que investigan el comportamiento del consumidor han llegado a la conclusión de que la satisfacción es un buen indicador, si no el mejor, de los futuros beneficios de las empresas. A partir de la década de 1990 se han desarrollado los índices nacionales de satisfacción como herramientas de evaluación macro desde el punto de vista del cliente para complementar las medidas objetivas de rendimiento económico tradicionales. En este trabajo se presenta una revisión teórica de los índices nacionales de satisfacción que más relevancia han tenido en entornos tanto profesionales como académicos, identificando las variab…

Una vida en imágenes: los daily photo projects y la retórica del instante

2009

Los daily photo projects son una práctica contemporánea que consiste en tomar una fotografía digital diaria de sus protagonistas hasta el día de su muerte. Las imágenes son ensambladas en un video que, de este modo, concentra sus vidas en minutos. Una vida entera es visualizada como si fuera una secuencia de instantes, de instantáneas. Son alegorías de la vida que muestran el proceso de envejecimiento a modo de espejo, lanzando una nueva mirada al tópico de la vanitas y del autorretrato. El montaje en video es lo que convierte a estos proyectos en vanitas en movimiento ya que la secuencia de fotografías muestra el proceso de envejecimiento. Daily photo projects are contemporary photographic…

Progressive non-linear damage of variable angle tow composite plates by a Ritz approach

2022

In this work a Ritz model for progressive non-linear damage analysis of variable angle tow composite plates is presented. The damage is treated in the framework of continuum damage mechanics and its evolution is based on a linear softening law with which four damage indices are computed for degrading the mechanical properties of the material. A set of analyses have been carried out to investigate how damage evolves in VAT composite plates under progressive loading.

Vascular Risk Factors in Mild Cognitive Impairment Subtypes

2007

<i>Background and Aim:</i> To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. <i>Methods:</i> Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. <i>Results:</i> snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and …

Neuronal effects of Sugammadex in combination with Rocuronium or Vecuronium.

2017

Rocuronium (ROC) and Vecuronium (VEC) are the most currently used steroidal non-depolarizing neuromuscular blocking (MNB) agents. Sugammadex (SUG) rapidly reverses steroidal NMB agents after anaesthesia. The present study was conducted in order to evaluate neuronal effects of SUG alone and in combination with both ROC and VEC. Using MTT, CASP-3 activity and Western-blot we determined the toxicity of SUG, ROC or VEC in neurons in primary culture. SUG induces apoptosis/necrosis in neurons in primary culture and increases cytochrome C (CytC), apoptosis-inducing factor (AIF), Smac/Diablo and Caspase 3 (CASP-3) protein expression. Our results also demonstrated that both ROC and VEC prevent these…

Author Correction: Evaluation of three methods for biomass estimation in small invertebrates, using three large disparate parasite species as model o…

2018

Invertebrate biomass is considered one of the main factors driving processes in ecosystems. It can be measured directly, primarily by weighing individuals, but more often indirect estimators are used. We developed two indirect and non-destructive approaches to estimate biomass of small invertebrates in a simple manner. The first one was based on clay modelling and the second one was based on image analysis implemented with open-source software. Furthermore, we tested the accuracy of the widely used geometric approximation method (third method). We applied these three different methods to three morphologically disparate model species, an acanthocephalan worm, a crustacean and a flatworm. To …

Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.

2011

Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…

L’image des légumes

2017

Au sein du vaste champ de recherche qu’est l’alimentation, les légumes et les représentations qu'en ont les mangeurs ont été délaissés malgré la place importante qu'ils occupent dans les discours officiels depuis la mise en place en 2001 du PNNS. Dans un contexte de stagnation de leur consommation, il semble judicieux de tenter de comprendre quels en sont les freins. Notre hypothèse veut que les discours médiatiques sur le sujet, dans la lignée du discours des autorités publiques, présentent les légumes avant tout comme un aliment fonctionnel, dans un pays où le goût et le plaisir restent pourtant des piliers de la culture alimentaire. Pour mettre à l’épreuve ce postulat, notamment à traver…
