Programa de Doctorado en Psicología Social ; Esta investigación estudia la relación entre distintos actores socio-políticos en el marco de la primavera árabe-amazigh en Marruecos. Los cambios superficiales experimentados, en relación a las demandas iniciales de apertura democrática, dan muestra de una alta resiliencia del régimen marroquí. El análisis está focalizado en la interacción de dos movimientos sociales. El Movimiento 20 de febrero, que lidera en 2011 el ciclo de contestación iniciado tras las revueltas tunecina y egipcia, y el Movimiento de Diplomados en Paro, uno de los más activos en Marruecos en las últimas décadas. Se analiza al mismo tiempo el papel de la intermediación del Estado, que se descubre como motivo principal de la ausencia de cristalización de la confluencia entre ambos movimientos. Desde un punto de vista teórico se estudian las identidades colectivas de ambos movimientos a partir de un enfoque constructivista y considerando el papel de la dimensión emocional en la evolución de los hechos. El trabajo empírico se ha basado en el análisis de noticias del periódico francófono Libération en el periodo de 2011 a 2014 y la realización de casi una treintena de entrevistas a activistas de ambos movimientos en las áreas geográficas de Rabat (centro) y Alhucemas (periferia). El movimiento 20 de febrero se identifica como un movimiento aglutinador de sectores sociales, políticos y sindicales (en menor medida) bajo el mínimo denominador de cambiar el régimen. Ante un Estado autoritario, utiliza fundamentalmente su herramienta discursiva, que le permite crear nuevos símbolos culturales y evidenciar relaciones sinérgicas representadas como imposibles, entre sectores islamistas y de izquierda. Estas nuevas realidades pasan a formar parte del imaginario colectivo y facilitan que el `espíritu del 20 de febrero¿ resurja en situaciones de vulneración de derechos a través de una reacción rápida social. La estrategia del Movimiento de Diplomados en Paro evoluciona en este nuevo escenario de protesta. El estudio analiza el cambio de una lógica clientelar, que ahoga el posible efecto transformador que hubiera supuesto un apoyo institucional al Movimiento 20 de febrero, a cierto alineamiento con este movimiento tras la experiencia de que las exigencias de democratización son necesarias para alcanzar sus objetivos.

AbstractIn this article we share our reflections on how childism has enabled us to navigate theoretical assumptions shaping our field and develop new positions and research practices fostering child–adult interdependencies. Justyna Deszcz‐Tryhubczak has relied on childism as a framework for the introduction of participatory research with young readers as a way for advancing child–adult collaboration. Macarena García‐González has deployed childism to think about adultism and its analogies to sexism. Although we offer a critique of childism as an essentializing concept, we also show how for both of us it has served as a gateway towards other approaches, and especially post‐anthropocentric understandings both of texts, readers and the world and of our critical engagements. Finally, we argue that childism may remain a productive starting point for further openings in children's literature and culture studies and childhood studies if it becomes a plural and messy notion that questions the discourse of hope for a better future as defining children's lives.

The PPC for PDPs implemented in Uruguay in recent years have provided fertile ground for research. Many have achieved results that can be analyzed within the scope of their respective histories and institutional settings. The study inquires about what PPCs maximize the benefits of PDP results and minimizes rent-seeking behavior or the capture of government. In other words, it wants to disentangle how did the PPCs selected balanced these two apparently conflicting goals. The results show that some PPCs managed these matters better than others did. A history of private-public collaboration at the sectoral level was a key factor in understanding the different results. The imposition of foreign regulations to export-intensive sectors is another factor that reduces the imbalance. Additionally, the PPCs' degree of sophistication and the lower risk of one-sidedness depend on the capacities of public and private actors. Finally, the study found that the PPC design that most likely has better results has to be consistent with the kind of good, that is, the public, club, or private good, the PDP is providing.

La sociedad actual impulsa la utilización masiva de la tecnología en todos los campos, incluyendo el ámbito educativo y, por extensión, la enseñanza y el aprendizaje que realizan las personas con necesidades específicas de apoyo educativo, dentro de las cuales se incluyen los sujetos con Síndrome de Down. Por esto, nuestro propósito es conocer cómo influye la implementación de los recursos tecnológicos en la educación de este colectivo, para lo cual hemos realizado una investigación bibliométrica, analizando los documentos hallados sobre el tema, escritos en los últimos quince años y publicados en cuatro bases de datos diferentes (Scopus, Eric, Google Académico y Dialnet). La muestra la componen 55 estudios cuyos principales resultados revelan que las Tecnologías de la Información y la Comunicación, bajo una metodología adecuada y con las pertinentes adaptaciones, son un recurso eficaz para acercar el currículum a dicha población, favoreciendo el desarrollo educativo, personal y social.

[Abstract] Optical Coherence Tomography Angiography (OCTA) constitutes a novel ophthalmological image modality that is characterized for being a non-invasive capture technique that allows a profound analysis of the vascular characteristics of the eye fundus. Given the restricted field of view of the eye fundus that offers each scan, the specialists frequently capture several complementary images that may be simultaneously analyzed to offer a complete and accurate diagnosis of the patient. In this work, we propose a fully automatic method to register complementary OCTA images and provide compositions for the same patient, generating a wide field of representation that allows a simpler and more direct analysis than the traditional tedious manual procedures. To achieve this, we based our proposal in a robust combination of representative features that are filtered by an accurate identification of the main retinal vasculature. This way, given the characteristic high irregularity in the fundus of the OCTA images, we avoid many variable areas that may interfere in the registration process, restricting the analysis to the most representative and stable structure of this image modality, the main retinal vasculature. In particular, we use Speeded-Up Robust Features (SURF) algorithm to extract representative features in the main vascular region that is extracted using a method that combines the analysis of the Hessian matrix followed by an hysteresis threshold process. Then, using a K-NN model, we perform the registration of the resulting features from the different OCTA images to be analyzed. Finally, the Random sample consensus (RANSAC) method is exploited to produce the final target mosaic. The proposed method presented satisfactory results in the validation experiments, with accurate values for the MSE index of 1.2566 and 1.6725 pixels for the registration of paired images an mosaics, respectively. ; Xunta de Galicia; ED431G/01 ; Xunta de Galicia; ED431C 2016-047 ; This work is supported by the Instituto de Salud Carlos III, Government of Spain and FEDER funds of the European Union through the DTS18/00136 research projects and by the Ministerio de Economía y Competitividad, Government of Spain through the DPI2015-69948-R research project.

[Abstract] Diabetic Retinopathy and Diabetic Macular Edema (DME) represent one of the main causes of blindness in developed countries. They are characterized by fluid deposits in the retinal layers, causing a progressive vision loss over the time. The clinical literature defines three DME types according to the texture and disposition of the fluid accumulations: Cystoid Macular Edema (CME), Diffuse Retinal Thickening (DRT) and Serous Retinal Detachment (SRD). Detecting each one is essential as, depending on their presence, the expert will decide on the adequate treatment of the pathology. In this work, we propose a robust detection and visualization methodology based on the analysis of independent image regions. We study a complete and heterogeneous library of 375 texture and intensity features in a dataset of 356 labeled images from two of the most used capture devices in the clinical domain: a CIRRUSTM HD-OCT 500 Carl Zeiss Meditec and 179 OCT images from a modular HRA + OCT SPECTRALIS® from Heidelberg Engineering, Inc. We extracted 33,810 samples for each type of DME for the feature analysis and incremental training of four different classifier paradigms. This way, we achieved an 84.04% average accuracy for CME, 78.44% average accuracy for DRT and 95.40% average accuracy for SRD. These models are used to generate an intuitive visualization of the fluid regions. We use an image sampling and voting strategy, resulting in a system capable of detecting and characterizing the three types of DME presenting them in an intuitive and repeatable way. ; Xunta de Galicia; ED431G 2019/01 ; This research was funded by Instituto de Salud Carlos III, Government of Spain, DTS18/00136 research project; Ministerio de Ciencia, Innovación y Universidades, Government of Spain, RTI2018-095894-B-I00 research project, Ayudas para la formación de profesorado universitario (FPU), grant ref.
