Un Sistema de ayuda a la escritura de textos estructurados en LaTeX para estudiantes con déficit visual
2011
La redacción y presentación de documentos estructurados grandes, especialmente si requieren notación matemática, puede resultar difícil para los alumnos ciegos o con déficit visual usando editores clásicos. El proyecto que se propone, aún en fase inicial, consiste en un sistema de ayuda a la escritura de textos en LATEX[2] que reconozca como órdenes simples de voz las principales marcas de este lenguaje y emita también por voz indicaciones útiles como errores, mensajes de estado, etc. Se discuten las ventajas del uso de lenguajes de marcado para personas ciegas, entre otras la posibilidad de conversión automática a cualquier otro formato (HTML,XML,...), la posibilidad de inclusión de tablas…
Self-generated Drawing: A Help or Hindrance to Learning from Animation?
2017
The considerable potential of animations to aid learning about dynamic systems too often remains unfulfilled when the targeted subject matter is complex and unfamiliar. Various approaches designed to support learning from animation in such cases have met with limited success. Recent studies on learning from demanding texts indicate that educational outcomes can be improved if learners are required to self-generate drawings during their study of a text. This improvement has been attributed to the role of drawing in fostering deeper learner processing of the presented information and superior self-regulation as learning proceeds. It is possible that learner self-generation of drawings during …
An Interactive Framework for Offline Data-Driven Multiobjective Optimization
2020
We propose a framework for solving offline data-driven multiobjective optimization problems in an interactive manner. No new data becomes available when solving offline problems. We fit surrogate models to the data to enable optimization, which introduces uncertainty. The framework incorporates preference information from a decision maker in two aspects to direct the solution process. Firstly, the decision maker can guide the optimization by providing preferences for objectives. Secondly, the framework features a novel technique for the decision maker to also express preferences related to maximum acceptable uncertainty in the solutions as preferred ranges of uncertainty. In this way, the d…
Tecnologías en la creación de imágenes en las aulas. Un estudio de casos en tres escuelas públicas
2018
Esta investigación forma parte del proyecto “Estudio de la calidad estética de tres centros educativos valencianos” que profundiza en las técnicas y tecnologías con las que están creadas las imágenes presentes en los colegios, como variable de la calidad educativa. La metodología de investigación es plural, al combinar métodos artísticos, cualitativos y cuantitativos. La recogida de datos consiste en fotografiar las imágenes que se muestran en las paredes de 27 aulas en 3 escuelas. Las fotografías se analizan cualitativamente según su tecnología. Mediante investigación basada en imágenes se clasifican según sus procesos de producción: mecánicos, manuales, o mediante tecnología mixta. Los re…
Aplicación, generalización y evaluación del programa PECS en un caso de Trastorno del Espectro Autista
2019
El presente artículo muestra un estudio de caso sobre intervención en la generalización de la comunicación que emplea un niño diagnosticado de TEA. El objetivo fue la creación, aplicación y evaluación de pautas que deben seguir los profesionales del Centro de Educación Especial en el que está matriculado, para que pueda generalizar las habilidades adquiridas del sistema PECS en el aula de audición y lenguaje, al aula de referencia. Para ello se ha seguido un método mixto, empleando el análisis documental, entrevistas y registros de observación cuantificables. A lo largo del proceso se diseñan y construyen las pautas, se realizan reuniones de coordinación, se implementan las instrucciones en…
Attributional and relational influence of numerals in S’ncamtho metaphors
2020
AbstractYouth varieties in Africa such as S’ncamtho, the Ndebele-based youth variety in Zimbabwe, and urban vernaculars interact with urban and modern experiences which offer them new materials and experiences to base their metaphors on compared to older metaphors in the base languages. This paper explores the use of numeral qualities and associations in the conceptualisation and orthographic representation of S’ncamtho metaphors. S’ncamtho is popular with urban youth and this makes social media platforms such as Twitter, Facebook, WhatsApp, SMS and Instagram key in the performance of the youth variety, a performance that includes the creation, use and contraction of metaphors. Numerals off…
A Randomized Trial of a Schlemm's Canal Microstent with Phacoemulsification for Reducing Intraocular Pressure in Open-Angle Glaucoma
2014
Purpose To assess the safety and effectiveness of the Hydrus Microstent (Ivantis, Inc, Irvine, CA) with concurrent cataract surgery (CS) for reducing intraocular pressure (IOP) in open-angle glaucoma (OAG). Design Prospective, multicenter, randomized, single-masked, controlled clinical trial. Participants One hundred eyes from 100 patients 21 to 80 years of age with OAG and cataract with IOP of 24 mmHg or less with 4 or fewer hypotensive medications and a washed-out diurnal IOP (DIOP) of 21 to 36 mmHg. Methods On the day of surgery, patients were randomized 1:1 to undergo CS with the microstent or CS alone. Postoperative follow-up was at 1 day, 1 week, and 1, 3, 6, 12, 18, and 24 months. Wa…
Re-thinking news: Information design and “antibody” contents
2022
Rethinking news and producing quality (“antibody”) contents as a remedy against the rampant proliferation of fake news (and the related erosion of democracy), starting from the values and approaches shared by the worlds of design and journalism can be - and certainly are - an effective and interesting way forward. The fertile confluence of the body of knowledge (and know-how) of these two disciplines has already produced excellent results, starting with design-driven experiments tried and tested in several significant experiences in Italy and abroad. As Paolo Ciuccarelli stated, “once again, designers as ‘meaning makers’ find today in the narrative of the world of the infosphere a design gr…
''Forward to the past''
2012
Carlini, Alessandro | Actis-Grosso, Rossana | Stucchi, Natale | Pozzo, Thierry; International audience; ''Our daily experience shows that the CNS is a highly efficient machine to predict the effect of actions into the future; are we so efficient also in reconstructing the past of an action? Previous studies demonstrated we are more effective in extrapolating the final position of a stimulus moving according to biological kinematic laws. Here we address the complementary question: are we more effective in extrapolating the starting position (SP) of a motion following a biological velocity profile? We presented a dot moving upward and corresponding to vertical arm movements that were masked i…
Analysis of neuronal networks in the visual system of the cat using statistical signals--simple and complex cells. Part II.
1978
Superimposing additively a two-dimensional noise process to deterministic input signals (bars) the neurons of area 17 show a class-specific reaction for the task of signal extraction. Moving both parts of the signals simultaneously and varying the signal to noise ratio (S/N) the simple cells achieve the same performance as resulted from the psychophysical experiment. Type I complex cells extract moving deterministic signals (i.e. bars) from the stationary noise, whereas in the answers of Type II complex cells the statistical parts of the signals predominate. Considering the different cell types each as a series of a linear and a nonlinear system one obtains the cell specific space-time freq…
