Evaluation of the wave energy density on the Sicilian coast
2016
In this article the wave energy density of the northern Sicilian coasts is evaluated and is used to evaluate the producibility of a wave nergy converter to be installed in an area in the north west part of Sicily. In particular, the objective of the study is the evaluation of a potential installation in an area between Trapani and Palermo, which are the largest cities in the north west part of Sicily. In particular in this research, the wave energy density of Sicily has been analyzed by using an analysis of wave data carried out in a 10-year period, using the measurements of buoyant of National Wave measuring System (RON - Rete Ondametrica Nazionale). The analysis shows that the north-weste…
The mechanically based non-local elasticity: an overview of main results and future challenges
2013
The mechanically based non-local elasticity has been used, recently, in wider and wider engineering applications involving small-size devices and/or materials with marked microstructures. The key feature of the model involves the presence of non-local effects as additional body forces acting on material masses and depending on their relative displacements. An overview of the main results of the theory is reported in this paper.
Atmospheric circulation modulates the spatial variability of temperature in the Atlantic-Arctic region
2019
International audience; The Arctic region has experienced significant warming during the past two decades with major implications on the cryosphere. The causes of Arctic amplification are still an open question within the scientific community, attracting recent interest. The goal of this study is to quantify the contribution of atmospheric circulation on temperature variability in the Atlantic–Arctic region at decadal to intra‐annual timescales from 1951 to 2014. Daily 20th Century reanalyses geopotential height anomalies at 500 hPa were clustered into different weather regimes to assess their contribution to observed temperature variability. The results show that in winter, 25% of the warm…
Les types de temps associés aux risques d’inondations et d’érosions en Camargue : éléments de diagnostic et de prospectives pour le 21e siècle (1993-…
2010
Les fortes surcotes marines et les fortes vagues sont les principaux aléas météo-marins associés aux risques de submersion et d’érosion du littoral camarguais. Sur la période 1993-2002, une forte fréquence mensuelle de très hautes surcotes marégraphiques est généralement associée à une forte fréquence de très hautes vagues. Ces deux phénomènes locaux se produisent principalement lorsqu'une dépression autour du Golfe de Gascogne est associée à des hautes pressions sur l’Europe Centrale. La fréquence mensuelle de ce type de temps nous renseigne sur la probabilité d’occurrence de fortes surcotes marégraphiques et vagues en Camargue. Au 21e siècle, la fréquence du type de temps associé aux plus…
Structural Equation Modeling in Research on Brand Capital in Higher Education
2016
This research is done in order to examine the role of the brand capital in higher education. For this purpose, we analyze the main contributions of the literature related to the study of the brand capital and its application in the educational sector, identifying which variables determine the brand capital in the higher education sector. Once we establish the susceptible brand capital in the higher education sector, an empirical research is done by using a questionnaire developed in Spanish language with a Likert scale of grade 5 in which 1 point means "strongly disagree" and 5 mean "strongly agree", being based on the measurement scales…
The linguistic construction of confirmation niches in online comment sequences
2018
This study starts from the consideration that new media are platforms where communication and language are re-negotiated to adapt new frames (e.g. new politeness, multimodal exchanges) and, in particular, that fora are participatory frameworks, that represent a mined engagement in writing practices (Stommel and Koole, 2010). Discussions are organised as multiparty conversations on several topics, written by participants (i.e website users accessing a parenting forum) at different levels of expertise about health issues (mostly earned through their experience of parenthood; Kata, 2010). the challenge in this paper is : 1) to study asynchronous forum as a talk-in -interaction venue, where seq…
Sbateyl.org: A Virtual Space for Effective Language Training
2016
AbstractThe paper presents an ongoing European cross-institutional project on teaching young language learners whose aim is to develop a web-based in-service teacher education programme with a school-based follow-up component. The main focus of the project is to bring researchers and teachers together to establish an innovative professional procedure blending theory and practice. Based on the strategic partnership between one local university and one primary school from each participant country, the project aims to foster the professional advancement and teaching practices of primary school teachers. The article initially outlines the main theoretical and methodological issues in the field …
Asking for medical help by posting on the net: genre, functions and ethical issues
2014
On the basis of the growing of the number of sites related to health issues and online conversation, statistical research tend to acknowledge that the communication practices of health message boards have significant roles to play in the era of online counseling (Anderson, 2003; Kim & Yoon, 2011; Mulholland, 1999; Eysenbach and Diepgen 1999; O'Connor and Johanson 2000; Shuyler and Knight 2003; Gooden and Winefield 2007). However, one of the main worries concerning these spaces has been the uncontrolled information that is provided by users with no defined roles and who do not/cannot take responsibility for what they say. Previous studies were intended to explore how people discussing health…
The influence of ENSO on South Africa winter rainfall
2011
International audience; We analysed the relationship between El Niño Southern Oscillation (ENSO) and South Africa austral winter rainfall using a 682 raingauges daily rainfall database documenting the period 1950-1999. The May, June and July (MJJ) seasonal rainfall amount shows a positive correlation with the Niño3.4 index that becomes significant since the mid 70's. Wet spells properties (length, frequency and intensity) at the raingauge scale indicate that high (low) MJJ seasonal rainfall amounts recorded during El Niño (La Niña) events are the result of longer (shorter) wet spells in the Cape Town area and more (less) frequent wet spells north of 33°S. Wet spells with daily rainfall amou…
The Trope of Sight in North American Whiteness Studies
2017
The trope of sight has been the central metaphor in North American whiteness studies sińce its very inception, that is, already before whiteness studies emerged as a separate field of study. The centrality of the trope stems not only ffom a particular applicability of the sight metaphor to render subject-object relations, but also ffom the unique presence of “sight” in the very relations between racial groups in the United States, in particular Alfican Americans, and whites. Originally, minorities were cast as objects of the gaze, while white people as subjects of the gaze, exercising the power to look, survey and pass judgment. Apart ffom exposing practices of looking employed by whites, w…
