Mesure du transport narratif dans le contexte d’une expérience de consommation transmédia
2018
This research offers a French narrative transportation scale measuring the experience of transmedia devices in the arts and cultural field. First, based on a literature review of the definition and measure of narrative transportation, a new scale is presented and defended. Second, a qualitative study is conducted. The dimensions of narrative transportation are confirmed and items are generated to measure it. Results from factorial analysis leading to a reliable and valid scale of narrative transportation lived by the cultural consumer through the use of a transmedia device are presented.
Canard-cycle transition at a fast–fast passage through a jump point
2014
Abstract We consider transitory canard cycles that consist of a generic breaking mechanism, i.e. a Hopf or a jump breaking mechanism, in combination with a fast–fast passage through a jump point. Such cycle separates two types of canard cycles with a different shape. We obtain upper bounds on the number of periodic orbits that can appear near the canard cycle, and this under very general conditions.
Social Media Marketing and Value Co-creation: A Dynamic Performance Management Perspective
2017
The diffusion of web-based technologies has transformed the today consumers, shifting them from mere users to content generators, able to influence each other’s opinions and choices. Such trend discloses important consequences for firms, products and brands. In order to support strategic and operational decision-making, this study frames the phenomenon of social media marketing into the value co-creation paradigm and shows how to design an analytical framework combining performance management and System Dynamics.
Anomalous water dynamics in brain: a combined diffusion magnetic resonance imaging and neutron scattering investigation
2019
International audience; Water diffusion is an optimal tool for investigating the architecture of brain tissue on which modern medical diagnostic imaging techniques rely. However, intrinsic tissue heterogeneity causes systematic deviations from pure free-water diffusion behaviour. To date, numerous theoretical and empirical approaches have been proposed to explain the non-Gaussian profile of this process. The aim of this work is to shed light on the physics piloting water diffusion in brain tissue at the micrometre-to-atomic scale. Combined diffusion magnetic resonance imaging and first pioneering neutron scattering experiments on bovine brain tissue have been performed in order to probe dif…
PODOLOGICAL ASPECTS OF FOOT CARE IN SOCIAL CARE CENTERS
2018
Investigate the necessity for therapeutic foot care and the involvement of a podologist in an interdisciplinary health care team in social care institutions in Latvia. So far, no study has been conducted on the need for therapeutic pediatric care for Social Care Center (SCC) clients in Latvia; it is known that in individual SCC’s where some podologists work part-time, another podologist is invited in specific cases, or clients are taken to a podologist at a medical institution. The study was conducted in 15 Latvian Social Care Centers (SCC), surveying 750 customer feet. People who, for various reasons, are no longer capable of foot care, is a highly necessary specialist who will do it profe…
Multi-method evaluation of denudation rates in small mediterranean catchments
2015
The paper presents the results of the research tasks of the Quantitative Geomorphology Working Group (of the Italian Association of Physical Geography and Geomorphology) focused on multi-method evaluation of denudation rates in small catchments of Italy. Several study areas are compared with the goal of quantifying the morphodynamic evolution in different response times and with traditional and innovative techniques. The final aims are the direct erosion monitoring, the geomorphic analysis for the comprehension of drainage basin morphodynamics, up to the geomorphological hazard evaluation. The catchments are key Mediterranean areas particularly sensitive to climatic and anthropic modificati…
Sensitivity of precipitation forecasts to convective parameterization in the October 2007 Flash Flood in the Valencia Region (Eastern Spain)
2018
Abstract. The Valencia region, on the Mediterranean coast of the Iberian Peninsula, is an area prone to torrential rains, especially the north of Alicante province and the south of Valencia province. In October 2007, a torrential rain event with accumulated rainfall values exceeding 400 mm in less than 24 h affected the aforementioned areas, producing flash floods that caused extensive economic losses and human casualties. Several simulations of this rain event have been performed with the Regional Atmospheric Modeling System (RAMS) to test the influence of the different convective parameterization scheme implemented in the model on the precipitation forecast.
Plant genetic resources and traditional knowledge on medicinal use of wild shrub and herbaceous plant species in the Etna Regional Park (Eastern Sici…
2014
Ethnopharmacological relevance: This paper illustrates the results of a study carried out in the Etna Regional Park (Eastern Sicily, Italy) concerning the traditional knowledge on medicinal use of wild plant species. It specifies contains the results of a quantitative analysis carried out for the first time. A total of 71 wild species are used for medicinal purposes. Two species, Astracantha sicula (Biv.) Greuter and Trifolium phleoides Willd., are little known as medicinal in the Mediterranean area. Aim of the study: The main aim of the study was to understand to what extent current knowledge on the medicinal use of plants is still an element of the culture within the elderly population of…
Environmental Metal Pollution Considered as Noise: Effects on the Spatial Distribution of Benthic Foraminifera in two Coastal Marine Areas of Sicily …
2008
We analyze the spatial distributions of two groups of benthic foraminifera (Adelosina spp. + Quinqueloculina spp. and Elphidium spp.), along Sicilian coast, and their correlation with six different heavy metals, responsible for the pollution. Samples were collected inside the Gulf of Palermo, which has a high level of pollution due to heavy metals, and along the coast of Lampedusa island (Sicily Channel, Southern Mediterranean), which is characterized by unpolluted sea waters. Because of the environmental pollution we find: (i) an anticorrelated spatial behaviour between the two groups of benthic foraminifera analyzed; (ii) an anticorrelated (correlated) spatial behaviour between the first …
Electrical Coupling in Ensembles of Nonexcitable Cells: Modeling the Spatial Map of Single Cell Potentials
2015
We analyze the coupling of model nonexcitable (non-neural) cells assuming that the cell membrane potential is the basic individual property. We obtain this potential on the basis of the inward and outward rectifying voltage-gated channels characteristic of cell membranes. We concentrate on the electrical coupling of a cell ensemble rather than on the biochemical and mechanical characteristics of the individual cells, obtain the map of single cell potentials using simple assumptions, and suggest procedures to collectively modify this spatial map. The response of the cell ensemble to an external perturbation and the consequences of cell isolation, heterogeneity, and ensemble size are also ana…
