Este estudio aborda el conflicto social y urbano que subyace en Alicante bajo la imagen publicitaria del tardeo. Durante la última década, se ha institucionalizado en las calles peatonalizadas del centro de la ciudad un modelo de ocio caracterizado por el consumo de alcohol en la vía pública, el ruido y la ocupación del espacio. El objetivo específico es la identificación y análisis de las posiciones discursivas de los principales actores sociales implicados. Estos discursos expresan las claves del conflicto investigado. En una ciudad turística de tamaño medio, el caso expuesto ilustra lógicas imperantes en contextos más amplios, inmersos en el tránsito del capitalismo de bienestar al capitalismo flexible. El ideal democrático deriva en la imposición de criterios de unos grupos sobre otros, apelando a una razón instrumental guiada por motivaciones económico-empresariales y amparada por las instituciones públicas. ; This study reports the social and urban conflict that underlies the advertising image of the 'tardeo' in Alicante (Spain). During the last decade, a leisure model characterized by alcohol consumption on the roads, noise and public space occupation has been institutionalized in the pedestrianized streets of the city centre. The specific objective is the identification and analysis of the discursive positions of the main social actors involved. These discourses express the keys to the conflict. In a medium-sized tourist city, this case illustrates prevailing logic in broader contexts, immersed in the transition from welfare capitalism to flexible capitalism. The democratic ideal leads to the imposition of criteria of one group over another, appealing to an instrumental reason guided by economic-business motivations and covered by public institutions.

RésuméL'article se propose d'étudier les pratiques de l'écriture dans l'Espagne de la fin du XVeau milieu du XVIIIesiècle, à travers la relation qui existe entre la fonction des textes et leurs conditions de production, de diffusion et de réception. Les formes de l'écrit résultent des différentes stratégies et objectifs poursuivis, appropriation publique (inscriptions, tables, pamphlets ou graffiti), ou circulation plus restreinte et privée (correspondances, livres de comptes, mémoires, journaux personnels, autobiographies). Cette distinction entre écritures publiques et privées ne doit cependant pas être entendue comme un concept fermé: il importe de mettre en évidence leurs interrelations.

In this article, a wave propagation model is presented as the first step in the development of a new type of transluminal procedure for performing elastography. Elastography is a medical imaging modality for mapping the elastic properties of soft tissue. The wave propagation model is based on a Kelvin Voigt Fractional Derivative (KVFD) viscoelastic wave equation, and is numerically solved using a Finite Difference Time Domain (FDTD) method. Fractional rheological models, such as the KVFD, are particularly well suited to model the viscoelastic response of soft tissue in elastography. The transluminal procedure is based on the transmission and detection of shear waves through the luminal wall. Shear waves travelling through the tissue are perturbed after encountering areas of altered elasticity. These perturbations carry information of medical interest that can be extracted by solving the inverse problem. Scattering from prostate tumours is used as an example application to test the model. In silico results demonstrate that shear waves are satisfactorily transmitted through the luminal wall and that echoes, coming from reflected energy at the edges of an area of altered elasticity, which are feasibly detectable by using the transluminal approach. The model here presented provides a useful tool to establish the feasibility of transluminal procedures based on wave propagation and its interaction with the mechanical properties of the tissue outside the lumen. ; University College London, United Kingdom ; Talentia scholarship (grant C2012H-75146405T-1) from the regional government of Andalusia, Spain ; the Ministry of Education and Science, Spain, grants DPI2017-83859-R, EQC2018-004508-P and UNGR15-CE3664 ; Andalusia, Spain, grants SOMM17/6109/UGR, B-TEP-026-UGR18, IE2017-5537 and P18-RT-1653

In this article, our previously developed wave propagation model for transluminal propagation based on a Kelvin Voigt Fractional Derivative wave equation is experimentally validated. The transluminal procedure uses the transmission and detection of shear waves through the luminal wall. The model was compared against high-speed camera observations in translucent elastography phantoms with similar viscoelastic properties to prostate tissue. An ad hoc cross-correlation procedure was used to reconstruct the angular displacement from the high-speed camera observations. Rheometry and shear wave elastography were used for characterising the shear wave velocity dispersion curve for the phantoms. Fractional viscoelastic properties were derived after fitting the dispersion curve to its analytical expression. Propagation features and amplitude spectra from simulations and high-speed camera observations ...

Los objetivos de este estudio son, primero, proponer una taxonomía de los marcadores de actitud más frecuentes utilizados en Twitter tras los comunicados del gobierno sobre el coronavirus, segundo, investigar si nos muestran que existe una aceptación del poder en España, así como un respeto a sus decisiones y, finalmente, identificar redes semánticas entre los marcadores de actitud. El corpus recopilado para el estudio está compuesto por los tuits que comentan los comunicados del Ministerio de Sanidad y Salud Pública desde el 12 al 16 de marzo de 2020. Una vez analizados los datos con las herramientas METOOL y GePhi, se observó que se desea una relación con el poder más cercana y que aumentaba la agresividad de los tuits. Finalmente, describimos las conclusiones de este estudio. ; The objectives of this study are to suggest a specific taxonomy for the attitude markers used in Twitter after government decrees about coronavirus and to investigate if attitude markers indicate that power distance is accepted in Spain and if government decisions are respected. Finally, we study semantic webs in attitude markers. The corpus compiled for this study is composed by the tweets to the decrees of the Ministry of Health and Public Health from 12th to 16th March 2020. We analysed the data with the tools METOOL and GePhi. In the results it was observed that Spanish citizens preferred a closer relationship with power and it was noticed an increase in aggressive language. Finally, conclusions were drawn.

33 Páginas; 7 Figuras; 3 Tablas ; This work studies the influence of cultivar and farming area on the sensory profile of green Spanish-style table olives, using Quantitative Descriptive Analysis. The lexicon developed was subsequently applied to samples of Gordal (G), Manzanilla (M), and Hojiblanca (H) from different origins: Arahal (A), Utrera (U), Alameda (Al), Estepa (E), Casariche (C), Alcalá de Guadaira (AG), Posadas (P), and Almendralejo (Am). The analysis of the data by ANOVA, considering the effect of the sample as fixed and those of the panelists and the sessions as random, showed good repeatability (no significant effect of the session). Bitter, salty, astringent, acid, alcohol and lupin descriptors had significant discriminating power. The samples were characterised by the following sensory attributes: HC, pungent and winery/wine; MP, salty and lupin; GA, acid and lactic acid; HAl, astringent and acetic/vinegar; and MAm, bitter and musty. The multivariate analysis combined with bootstrapping techniques offered a multidimensional view of repeatability, relationships among descriptors, and characterisation and segregation of products. The results then pointed to sensible differences among the sensory profiles of the samples due to cultivar and origin. ; This work was supported in part by the Ministry of Economy and Competitiveness from the Spanish government through Project AGL2014-54048-R, partially financed by the European Regional Development Fund (ERDF).
