Introduction to the semiotics of the text
2021
This books aims to demonstrate how semiotic models of textual analysis can be used to study any social reality or cultural process. In addition, it shows how semiotic models work by using examples from everyday life and social praxis, communicative processes and modes of consumption, online interactions and cross-media procedures, political experiences and scientific universes.
Early development of hedonic and motivational aspects of eating behaviour
2015
Eating is essential for survival. However, the newborn is not an autonomous eater, and has to learn ‘how', ‘what', ‘when', and ‘how much' to eat quickly enough to ensure harmonious growth and development. In other nutritional areas, it has been shown during the past 20 years that early experiences are likely to impact long-term health outcomes. Thus, it appears fundamental to understand the early development of hedonic and motivational aspects of eating behaviour. This presentation will describe several studies conducted in our group during the past 10 years, in order to gain more knowledge about the development of what and how much children eat, in relation with food sensory and nutritiona…
Sex-specific signatures of intrinsic hippocampal networks and regional integrity underlying cognitive status in multiple sclerosis
2021
Abstract The hippocampus is an anatomically compartmentalized structure embedded in highly wired networks that are essential for cognitive functions. The hippocampal vulnerability has been postulated in acute and chronic neuroinflammation in multiple sclerosis, while the patterns of occurring inflammation, neurodegeneration or compensation have not yet been described. Besides focal damage to hippocampal tissue, network disruption is an important contributor to cognitive decline in multiple sclerosis patients. We postulate sex-specific trajectories in hippocampal network reorganization and regional integrity and address their relationship to markers of neuroinflammation, cognitive/memory per…
Sexes in gynodioecious Geranium sylvaticum do not differ in their isotopic signature or photosynthetic capacity
2017
In gynodioecious plants, females are expected to produce more or better seeds than hermaphrodites in order to be maintained within the same population. Even though rarely measured, higher seed production can be achieved through differences in physiology. In this work, we measured sexual dimorphism in several physiological traits in the gynodioecious plant Geranium sylvaticum. Photosynthetic rate, stomatal conductance, transpiration rate, WUE and isotopic signatures were measured in plants growing in two habitats differing in light availability. Females have been reported to produce more seeds than hermaphrodites. However, we did not observe any significant difference in seed output between …
How long is the sign?
2015
AbstractThis paper deals with the relative empirical length of signs in sign languages and provides evidence for the view that they are actually longer units than has hitherto been recognized. The evidence is presented from two perspectives: those of sign articulation and sign recognition. Concerning sign articulation, it is suggested that signs are longer units than is currently assumed because most of the structural features of signs are in fact already present before the currently accepted beginnings of signs and they continue after signs' generally accepted endings. Concerning sign recognition, the longer view of the sign is proposed on the grounds that the recognition point of signs is…
PALABRAS MORALES EN LAS CONSTITUCIONES. UNA CUESTIÓN DE LECTURAS
2012
Resumen: El presente trabajo pretende indagar y analizar las fuentes de significado de las diferentes referencias morales contenidas en las constituciones. El trabajo, así, envolverá varias posibles interpretaciones o “lecturas” acerca de tales fuentes de significado. Por ejemplo, se analizará una lectura intencional, una lectura literal, una lectura moral, una lectura pragmática. Todas ellas consecuentes con los tipos de interpretación más usuales en la literatura iusfilosófica actual. Tras apuntar los diversos inconvenientes de todas esas lecturas, en el trabajo se apostará por una “lectura personal”, es decir, por la subjetividad como fuente de significado de las palabras morales en las …
Physiological parameters measurements in a cardiac cycle via a combo PPG-ECG system
2015
In this paper, we present an innovative way to measure some physiological parameters (such as the pre-ejection period, the pulse transit time, the blood pressure) in a cardiac cycle. A combo PPG-ECG system has been developed and employed to extract both the ECG signal from standard limb leads and simultaneously the photoplethysmography signal from the wrist and the forearm, to calculate the pre-ejection period. This system represents an easy and non-invasive technique to determine these biomedical parameters without using expensive impedance cardiography equipment.
I segni parlano. Prospettive di ricerca sulla Lingua dei Segni Italiana
2008
I segni parlano perché cominciano a farsi più visibili nella società italiana: le ricerche sulla Lingua dei Segni Italiana (LIS) – avviate in modo sistematico in Italia dagli inizi degli anni ‘80 – sono aumentate rispetto a diversi anni fa, così come è aumentata la consapevolezza dell’importanza di questa lingua, non solo per le persone sorde. È una lingua infatti che sempre più persone – familiari, amici e colleghi di persone sorde, operatori, insegnanti, studenti – desiderano apprendere ed utilizzare non solo per necessità ma per avvicinarsi a nuove modalità comunicative. Una lingua che purtroppo ancora oggi sente il peso del pregiudizio e fatica a liberarsi di quel senso di inferiorità r…

Putative sorting signals involved in PIN1 trafficking
2013
Las auxinas son hormonas vegetales involucradas en muchos procesos fisiológicos, tales como el crecimiento y diferenciación celular, la maduración de los frutos, la floración o los tropismos. Su transporte a través de la planta es polar, jugando un papel esencial en la regulación del crecimiento y el desarrollo y contribuyendo al mantenimiento de la polaridad global de la planta. La polaridad en el flujo de auxinas es debida, al menos en parte, a la distribución polar de los transportadores de salida de auxina de la familia PIN. En Arabidopsis thaliana se han identificado 8 transportadores PIN diferentes. Todos ellos presentan una estructura similar, con un dominio citosólico central que se…
