Purpose: To determine the scientific evidence about the prevalence of accommodative and nonstrabismic binocular anomalies. Methods: We carried out a systematic review of studies published between 1986 and 2009, analysing the MEDLINE, CINAHL, FRANCIS and PsycINFO databases. We considered admitting those papers related to prevalence in paediatric and adult populations. We identified 660 articles and 10 papers met the inclusion criteria. Results: There is a wide range of prevalence, particularly for accommodative insufficiency (2 %-61.7 %) and convergence insufficiency (2.25 %-33 %). More studies are available for children (7) compared with adults (3). Most of studies examine clinical population (5 studies) with 3 assessed at schools and 1 at University with samples that vary from 65 to 2048 patients. There is great variability regarding the number of diagnostic signs ranging from 1 to 5 clinical signs. We found a relation between the number of clinical signs used and prevalence values for convergence insufficiency although this relationship cannot be confirmed for other conditions. Conclusion: There is a lack of proper epidemiological studies about the prevalence of accommodative and nonstrabismic binocular anomalies. Studies reviewed examine consecutive or selected patients in clinical settings and schools but in any case they are randomized and representative of their populations with no data for general population. The wide discrepancies in prevalence figures are due to both sample population and the lack of uniformity in diagnostic criteria so that it makes difficult to compile results. Biases and limitations of reports determine that prevalence rates offered are only estimations from selected populations.

Este artículo analiza diversas manifestaciones publicitarias aparecidas en la prensa española de los siglos XVIII y XIX. Considerando que la publicidad moderna nace en los países primero industrializados en torno a esas fechas, esta investigación se ha planteado la hipótesis de que en España, aun con retraso, se inició un proceso similar. Para la recopilación y selección de hechos, hemos utilizado las colecciones digitalizadas de portales que recientemente ofrecen el acceso libre a sus fondos; en particular, los de la Biblioteca Nacional de España, el Archivo de Revistas Catalanas Antiguas y la Hemeroteca Municipal de Madrid.

Este trabajo presenta la metodología empleada para compilar un corpus económico e identificar su terminología con el fin de crear un glosario de utilidad en la formación de traductores. Por una parte, se repasa brevemente la bibliografía sobre compilación de corpus y explotación con fines terminológicos. Por otra parte, se presenta la metodología en cuestión, así como una serie de actividades enfocadas a la adquisición de conocimiento especializado en economía. Los resultados muestran que las técnicas usadas para detectar términos y extraer automáticamente candidatos a término, si bien no terminan de adecuarse a las necesidades concretas del presente trabajo, son de utilidad e incluso pueden complementarse. Por su parte, las actividades propuestas pueden sumarse igualmente a otro tipo de actividades y modificarse según el contexto docente.

The retina is a very complex neural structure, which performs spatial, temporal, and chromatic processing on visual information and converts it into a compact ‘digital’ format composed of neural impulses. This paper presents a new compiler-based framework able to describe, simulate and validate custom retina models. The framework is compatible with the most usual neural recording and analysis tools, taking advantage of the interoperability with these kinds of applications. Furthermore it is possible to compile the code to generate accelerated versions of the visual processing models compatible with COTS microprocessors, FPGAs or GPUs. The whole system represents an ongoing work to design and develop a functional visual neuroprosthesis. Several case studies are described to assess the effectiveness and usefulness of the framework.
