This study investigated the incidental acquisition of second language (L2) vocabulary through the viewing of a 30-minute science documentary and the effect of captioning on this process. Thirty-four English language learners watched two documentaries (one captioned and one uncaptioned) and were then assessed on their knowledge of a set of words appearing in the documentaries. Results of the Vocabulary Tests (Form-recall/Spelling, and Meaning recognition) showed that documentary viewing led to significant acquisition of new vocabulary and that the captioning condition had a significant effect on this learning. Captioning boosted the gains on meaning recognition, form recall and spelling. Results indicated that relative gains in the captioning condition are 8% significantly higher than in the uncaptioned condition.

The Protective Area of the Escazú Hills (ZPCE, Spanish acronym) is an area designated as a pollution sink within theWestern Central Valley (VCO, Spanish acronym), in Costa Rica. For this study, the total deposition characteristicsobtained in the ZPCE during 2015’s rainy season were analyzed. The pH parameters and field conductivity wereassessed. The Cl-, SO4-2 and NO3- anions were determined by ion exchange chromatography while the Ca+2 andMg+2 cations were analyzed by atomic absorption. It was possible to identify acid rain (pH less than 5.6) in 90%of the ZPCE samples. There is more acidic pH distribution in the northwest part of ZPCE. The pH, as H+ concentration,presents a moderate conductivity correlation (0.585), according to Kolhraush’s law. The most abundant rainions collected are as follows, in decreasing order: CO3-2 > Cl- > SO4-2> NO3-. The ion correlations were high(more than 0.7) between Cl- and Mg + 2, between Ca+ 2 and CO3-2 and moderate (more than 0.4) between SO4-2and NO3-.

Este texto reflexiona sobre la importancia de las evaluaciones del impacto sobre la dinámica inmobiliaria, provocado por la implementación de una obra pública, particularmente un sistema de transporte colectivo. Para ello, se comenta de manera general sobre los impactos producidos por proyectos de transporte, haciendo énfasis en las fluctuaciones de los valores inmobiliarios. Así también, se expone el estado de la investigación y reflexión sobre valor y gestión del suelo en el Ecuador, para dejar en evidencia que, a pesar de que la legislación nacional actual motiva la aplicación de herramientas de gestión del suelo, aún existe un importante camino por recorrer en la disponibilidad de información sobre valores inmobiliarios. Para asentar la reflexión, se toma el caso de Cuenca, en donde se construyó un sistema tranviario entre los años 2013-2019, y se relatan las dificultades metodológicas enfrentadas para evaluar el impacto sobre los precios reales de las propiedades. Constatar y poner en evidencia estos retos tiene gran relevancia en el contexto latinoamericano, ya que solo a través de compartir experiencias se podrá conformar un cuerpo metodológico para futuros estudios en la región. Este tipo de reflexiones reivindican la necesidad de incluir, dentro de las agendas públicas de los gobiernos locales, el levantamiento y análisis de los valores de venta y de arriendo, de las propiedades.Palabras clave: Impacto urbano, dinámica inmobiliaria, transporte público, Cuenca, tranvía, valor del suelo. AbstractThis text reflects on the importance of impact assessments on real estate dynamics, caused by the implementation of public works, specifically a collective transport system. For this purpose, the impacts produced by transportation projects are discussed in a general way to emphasize the fluctuations of real estate values. Similarly, the state of research and reflection on land value and management in Ecuador is exposed, to elucidate that, although the current national legislation encourages the application of land management tools, there is still a long way to go in the availability of information on real estate values. To start the discussion, the case of Cuenca, where a tramway system was built between 2013-2019, is taken into consideration. The methodological difficulties faced to assess the impact on real property prices are reported in this research. Verifying and highlighting these challenges have great relevance in the Latin American context since only through sharing experiences a methodological body can be formed to carry out future studies in the region. These types of reflections claim the need to include, within the public agendas of local governments, the lifting and analysis of the sale and lease values of the properties.Keywords: Urban impact, real estate dynamics, public transport, Cuenca, tram, land value.

La vivienda es un bien que todo ser humano desea adquirir como necesidad prioritaria, atiende aspectos sociales, culturales, de seguridad, salud y bienestar, tanto individuales como colectivos. El estudio tiene por objetivo el sintetizar la información sobre construcciones sostenibles con materiales ecológicos en viviendas de interés social como aporte al hábitat urbano. La investigación se desarrolla bajo una revisión sistemática a través del buscador académico Google con las palabras clave: construcciones sostenibles; hábitat urbano; materiales ecológicos en la construcción y viviendas de interés social; de dicha búsqueda se seleccionaron los 30 artículos formales para el estudio, los que fueron evaluados inicialmente con la lectura rápida del título y resumen; posterior a ello se analizaron los criterios de inclusión y exclusión, y como último filtro se examinaron las variables específicas establecidas para el estudio. Las publicaciones revisadas muestran que es posible acceder a Viviendas de Interés Social sostenibles construidas con eco materiales que coadyuven al hábitat urbano, se concluye además que el uso de materiales ecológicos y el diseñar con criterios de arquitectura bioclimática reducirán los gastos económicos en el uso de energía eléctrica y agua, y por ende minimizar el impacto ambiental. Palabras clave: Construcciones sostenibles; hábitat urbano; materiales ecológicos en la construcción; viviendas de interés social. Abstract Housing is an asset that every human being wants to acquire as a priority need, which addresses social, cultural, safety, health, and welfare aspects, both individually and collectively. The study aims at synthesizing information on sustainable constructions built with ecological materials, and which represent housing of social interest as a contribution to urban habitats. The research is carried out under a systematic review through the Google academic search engine under the keywords: sustainable constructions; urban habitat; ecological materials in construction and housing of social interest. From this search, 30 formal articles were selected for the study which were initially evaluated with a fast reading of the title and summary. After that, the inclusion and exclusion criteria were analyzed, and as a last filter, the specific variables established for the study were examined. The revised publications show that it is possible to access sustainable social interest housing built with eco-materials that contribute to the urban habitat. It is also concluded that the use of ecological materials and designing with bioclimatic architecture criteria will reduce the economic expenses in the use of energy, electricity, and water, and therefore minimize the environmental impact. Keywords: Sustainable constructions; urban habitat; ecological materials in construction; social interest housing.

En Cuenca existe un déficit cuantitativo de 45000 viviendas (INEC, 2011). Este y otros problemas como el costo excesivo del suelo en la zona central de la urbe, ocasionan que la ciudad se extienda hacia su periferia. Como consecuencia los conjuntos habitacionales se construyen cerca del límite urbano. El estudio analizó los efectos sociales y espaciales que genera la ubicación de estos proyectos, específicamente del conjunto habitacional “Las Praderas de Bemani” y su contexto inmediato desde los dos enfoques planteados en este estudio. Por un lado, el enfoque territorial: su ubicación, que determina la cercanía a servicios básicos e infraestructura; por otro, el enfoque social: el derecho a la ciudad, la calidad de vida y la interacción entre diferentes grupos sociales. Metodológicamente se planteó una investigación de carácter mixto, se utilizó instrumentos cualitativos y cuantitativos: encuestas y análisis cartográfico. Los resultados obtenidos evidenciaron la existencia de segregación social y espacial, al interior y al exterior del proyecto.Palabras clave: Segregación social, segregación espacial, ciudades intermedias, conjuntos habitacionales, satisfacción residencial, vivienda Ecuador. AbstractIn Cuenca there is a quantitative deficit of 45,000 households (INEC, 2011). This and other problems such as the excessive cost of land in the central area of the city have caused its expansion to the periphery. As a consequence, housing complexes are built near the urban limit. Thus, this study analyzed the social and spatial effects generated by the location of these projects, specifically the housing complex “Las Praderas de Bemani” and its immediate context from the two approaches proposed in this study. On the one hand, the territorial approach: the location, which determines the proximity to basic services and infrastructure. On the other side, the social approach: the right to the city, the quality of life and the interaction between different social groups. Methodologically, a mixed research was proposed, qualitative and quantitative instruments were used: surveys and a cartographic analysis. The achieved results evidenced the existence of social and spatial segregation, inside and outside the project.Keywords: Social segregation, spatial segregation, intermediate cities, housing complexes, residential satisfaction, housing Ecuador.

El territorio de las ciudades puede segmentarse de acuerdo a criterios que van desde lo morfológico hasta las zonificaciones, permiten un análisis espacial que puede explicar los fenómenos que suceden en las urbes. El presente trabajo expone la conveniencia de hacer dicha identificación de zonas haciendo el estudio de los espacios urbanos a partir de las características de los objetos que existen en ellos, bajo la premisa de que de ello deriva gran parte de la percepción e imaginario que se tiene del entorno, lo que nos hace actuar en consecuencia. Se explora qué elementos se pueden seleccionar y cómo se pueden clasificar. Finalmente se esboza una propuesta metodológica para realizar una cartografía de zonas con identidades específicas de acuerdo a sus objetos. Palabras clave: Elementos urbanos, entorno, objetos, percepción.Abstract The territory of cities can be segmented according to criteria ranging from morphological to zoning. This allows a spatial analysis that can explain the phenomena that occurs in cities. The present work exposes the convenience of making the identification of areas by studying urban spaces based on the characteristics of the objects that exist in them under the premise that much of the perception and imaginary that is derived from the environment makes us act accordingly. The study explores the elements that can be selected and how they can be classified. Finally, a methodological proposal is outlined to create a mapping of areas with specific identities according to their objects. Keywords: Urban elements, environment, objects, perception.

The present article analizes Alejandro Zambra’s novel Ways of Going Home considering its structure and the way of writing that it draws on. In order to do so, Carlos Hernandez’ nominations about the poetics of fragments are considered.  In this context, it explains the fragmentariness and the metafiction of the writing as strategies that reflect the Chilean post-dictatorial disintegration and the way that this resource is used to find a suitable language to properly portray grief.

España, aparta de mí estos premios [Spain, Take These Awards from Me] (2009) by Fernando Iwasaki establishes, no doubt, a connection to the well-known text by Peruvian poet César Vallejo, España, aparta de mí este cáliz[Spain, Take This Cup from Me]. This paper compares the lyric voice in Vallejo’s poem and the narrative voice in Iwasaki’s text. This comparison leads to an exploration of the way in which Spain is represented in two different historical times. In other words, what is the Transatlantic relation posed by Iwasaki? How can we compare this relation to the possible relation suggested by Vallejo? What views of Spain does Iwasaki represent in the narratives?

In this paper, I discuss some aspects of one of the thorniest problems of the theory of discourse processing: The role of knowledge in the production and understanding of discourse. Although there are a large number of articles and books on this topic, some very fundamental questions have as yet hardly been asked. Firstly, I review the scant references to the role of knowledge in discourse processing and then I outline a tentative typology around four groups of knowledge. I then address the key question of how these different types of knowledge play a role in discourse processing, focusing on some hypothetical processes involved in the production of discourse. I finish with a call for an explicit theory of text processing that integrates context models.
