Homeostasis in school science: analysis of the subject and results of a proposal for classroom work

2016

El trabajo presenta un breve repaso del nacimiento del concepto de homeostasis en la historia de la fisiología. Se ha realizado un estudio de aula con estudiantes de tercer curso de secundaria apreciando las dificultades que estos presentan para construir una visión holista del concepto de homeostasis. La ciencia escolar porta una iconicidad múltiple, derivada del lenguaje experto, que en muchos casos se revela como un obstáculo para el aprendizaje de los estudiantes novatos. Siendo la homeostasis un concepto básico en la estructura del curriculum nacional se hace una llamada para ahondar en su investigación didáctica.

The iconic interface for the PIctorial C language

2003

Iconic environments intend to provide expressive tools to implement, to debug and to execute programs. Moreover its pictorial constructs guide the user to design algorithms in an interactive fashion. Visual interfaces are especially required whenever programs run on an heterogeneous and reconfigurable multiprocessor system oriented to image analysis. Pictorial tools help the user to control the scope of variables, and the distribution of the tasks into the processors. In this paper, the general design, the visual-syntax, and the implementation of the first prototype of an iconic user interface for the PIctorial C Language (PICL) are described. >

An Iconic Framework for Learning the Art of Programming

2016

The integration of programming teachings, in all levels of education, highlights the need to acquire the art of programming for each individual student through versatile tools based on specific cognitive methods. Diversified linguistic metaphors have to be adopted by the developing frame, in order to highlight the qualities of each student. Therefore, a framework, oriented to learning the art of programming, must foster polychrome constructs representations, a number of data structures and an intuitive interfaces in order to make easier to understand the evolution of the algorithm that have to be developed. The following contribution will present a theoretical formalization of a framework f…

Estrategias icónicas en las comedias mitológicas de Calderón

2015

El artículo explora el tópico horaciano «ut pictura poiesis», que tan buenos resultado ha ofrecido sobre el análisis de los textos calderonianos, pero no solo: también incorpora la relación de otras artes (música, escenografía, etc.) para estudiar el complejo entramado de las comedias mitológicas de Calderón que fueron representadas en entornos cortesanos. De este modo, la autora rastrea las interacciones artísticas existentes entre obras de destacada importancia como la fiesta palaciega “La fiera, el rayo y la piedra”, “La púrpura de la rosa” o “El hijo del sol, Faetón”. This paper explores the Horacian topic «ut pictura poiesis» which has offered such good results on the analysis of calde…

An interpretative and cognitive semiotic approach to the learning process of mathematical objects

Post-fotografia etnografica

2021

È evidente come la nostra società tecnologica sia legata senza alcun dubbio alla diffusione delle immagini. Autori come Gottfried Boehm, John Mitchell, Hans Belting hanno indagato la natura dell'immagine ponendo le basi, negli anni Novanta, per l'idea di un pictorial turn, di una cultura totalmente dominata dalle immagini che è diventata adesso una possibilità tecnica reale su scala globale. Un nuovo statuto dell'immagine che si usa raccogliere sotto l'etichetta di iconic turner inserito nel più vasto campo visual culture studies. L'uso del termine cultura accanto a quello di visuale è indicativo dell'ampiezza del campo d'indagine che visual culture studies si prefiggono di ricercare: essi …

Introduction : formes de l'iconicité

2014

International audience; L'emploi du terme "eikon" pour désigner une forme linguistique fonctionnant comme une image est aussi ancien que la tradition linguistico-grammaticale de l'Occident. Il figure en effet pour la première fois dans le Cratyle de Platon (439a), point de départ de cette tradition. Pour Platon, qui ne distingue pas encore entre signifiant et signifié, il est raisonnable d'affirmer que le nom, dans son ensemble, et jusqu'à ses éléments phonologiques, opère comme une image de la chose signifiée, ce qui constitue du reste une bonne raison pour s'en méfier et préférer la connaissance directe des choses à celle de leurs représentations. La reprise du terme "icon" dans la pensée…

A Geometric Approach to Automatic Description of Iconic Scenes

2005

It is proposed a step towards the automatic description of scenes with a geometric approach. The scenes considered are composed by a set of elements that can be geometric forms or iconic representation of objects. Every icon is characterized by a set of attributes like shape, colour, position, orientation. Each scene is related to a set of sentences describing its content. The proposed approach builds a data driven vector semantic space where the scenes and the sentences are mapped. Sentences and scene with the same meaning are mapped in near vectors and distance criteria allow retrieving semantic relations.

Clausal coordination in Finnish Sign Language

2016

This paper deals with the coordination of clauses in Finnish Sign Language (FinSL). Building on conversational data, the paper first shows that linking in conjunctive coordination in FinSL is primarily asyndetic, whereas in adversative and disjunctive coordination FinSL prefers syndetic linking. Secondly, the paper investigates the nonmanual prosody of coordination: nonmanual activity is shown both to mark the juncture of the coordinand clauses and to draw their contours. Finally, the paper addresses certain forms of clausal coordination in FinSL that are sign language-specific. It is suggested that the sign language-specific properties of coordination are caused both by the fact that signe…

Acousto-optic interaction in biconical tapered fibers: shaping of the stopbands

2016

The effect of a gradual reduction of the fiber diameter on the acousto-optic (AO) interaction is reported. The experimental and theoretical study of the intermodal coupling induced by a flexural acoustic wave in a biconical tapered fiber shows that it is possible to shape the transmission spectrum, for example, substantially broadening the bandwidth of the resonant couplings. The geometry of the taper transitions can be regarded as an extra degree of freedom to design the AO devices. Optical bandwidths above 45 nm are reported in a tapered fiber with a gradual reduction of the fiber down to 70 μm diameter. The effect of including long taper transition is also reported in a double-tapered st…
