A Spanish Sign Language (LSE) Adaptation of the Communicative Development Inventories

This article presents the adaptation of the MacArthur Communicative Development Inventory (CDI; Fenson et al., 1993, 1994) to Spanish Sign Language (LSE). Data were collected from 55 participants (32 boys and 23 girls; 17 deaf signers, 38 hearing signers) who, evaluated by their caregivers every four months, presented a total of 170 records. The parents reported the signs that the children could understand or produce between 8-36 months. Results suggested that the CDI adapted to LSE is a valid and reliable instrument. Signing children could understand more signs than they produced at this early developmental stage. There were no significant differences between boys and girls, or between deaf and hearing children. The development of LSE is similar to other sign languages, although with a lower production of signs in the early stages, perhaps due to the bilingualism of most of the children of our study.Se presenta la adaptación a la lengua de signos española (LSE) del Inventario de Desarrollo Comunicativo MacArthur (CDI; Fenson et al., 1993, 1994). Se recogieron datos de 55 participantes (32 niños y 23 niñas; 17 niños y niñas sordos signantes y 38 oyentes signantes), que, evaluados cada cuatro meses por sus cuidadores, representaron un total de 170 registros. Los padres y madres informaron de los signos que los niños podían producir o comprender entre los 8 y 36 meses. Los resultados sugieren que el CDI adaptado a la LSE es un instrumento válido y fiable. Los niños signantes podían entender más signos que producir en esta etapa del desarrollo temprano. No hubo diferencias significativas entre niños y niñas o entre niños sordos y oyentes. El desarrollo de la LSE es similar a otras lenguas de signos, aunque con una menor producción de signos en las etapas iniciales, quizás debido al bilingüismo de la mayoría de los niños del estudio.Consejería de Innovación, Ciencia y Empresa, Junta de Andalucía (España), Proyectos de Excelencia (P11-SEJ-7417)

Visualizando Signos

Os signos e as classes dos signos estão entre os tópicos mais importantes do sistema filosófico de Charles S. Peirce. As 10, 28, e 66 classes de signos são classificações desenvolvidas especialmente a partir de 1903 e representam um grande refinamento da divisão fundamental de signos – ícone, índice, símbolo. Nossa abordagem aqui define uma estratégia de visualização das classificações dos signos, com especial atenção para as 10 e 66 classes de signos. O livro está dividido em duas partes: (i) bases teóricas, (ii) diagramas para as classes de signos. Na Parte I (bases teóricas), são apresentadas introdutoriamente as noções fundamentais das categorias fenomenológicas, classes de signos, as tricotomias e diagramas, assim como implicações gerais de nossa abordagem, metodologia e aplicações. Na Parte II (diagramas para as classes de signos), são apresentados e discutidos os modelos das classes, propostos por Peirce e seus comentadores, incluindo uma introdução detalhadamente documental de nossos modelos, 10cubes e 3N3, diagramas dinâmicos para as classes de signos

Recent work based on an approximation method suggested some odd behaviors may be possible in solutions to a generalized model for compact stars. We show that it was the error in these approximations and error coming from non-physical boundary conditions which lead to the odd behavior. As it turns out, the generalized model for compact stars actually admits an exact solution, and we obtain this exact solution in closed form. The exact solution agrees with what one would physically expect from a compact star, and hence we use this solutions to calculate various quantities of physical interest in closed form, without having to resort to approximations
