DESLAZAMIENTOS EN LA CUENCA DEL RIO BANANO, UNA CONSECUENCIA DEL TERREMOTO DE ABRIL DE 1991

En la región Caribe algunas cuencas se vieron afectadas en su comportamiento hidrológico, como consecuencia del terremoto de abril de 1991.Un ejemplo evidente de lo anterior es la cuenca del rio Banano, que es la fuente principal del agua potable para la provincia de Limón, y que se presenta un comportamiento de rio aluvial acelerado como consecuencia de cerca de 40 millones de m3 de material deslizado. Los deslizamientos  característicos en la cuenca son deslizamientos de roca (rockslide), aunque puede observarse uno de tipo rotacional (rotational slump); además existen flujos de detritos ( debris flow). Este comportamiento acelerado origina inundaciones en poblados como Aguas Zarcas, Quitaría, Beverly; Polonia, Bomba y María Luisa. Con el fin de minimizar las consecuencias de estas inundaciones se establece una zonificación de áreas inundables para la parte baja de la cuenca en tres clases. Además, en la cuenca se registra un aporte significativo de material en suspensión, lo cual podrá alterar la posibilidad del agua. ABSTRACTThe April 1991 earthquake in Costa Rica caused changes in the hydrological characteristics of several watersheds in the Caribbean region of country.Evidence of these changes was observer in the rio Banano, the principal source of potable water for the province de Limon. The behavior of the alluvial river accelerated as a consequence of nearly 40 million cubic meters of material that moved within the watershed as a result of the earthquake. The characteristical landslides were rockslides, althoung rotational slump and debris flow slides were also observed. The accelerated hydrological changes in the river have caused flooding in populated areas such as Aguas Zarcas, Quitará, Beverly, Polonia, Bomba and Maria Luisa. In order to minimize the consequences of the flooding, the lower part of the watershed was classified in three categories according to flooding susceptibility.The river has also shown an increase in suspended material, which could affect the potability of the water.

EL TERREMOTO DE FRAIJANES DEL 1888 Y EL SISTEMA DE FALLAS DE ALAJUELA, IMPLICACIONES DEL PELIGRO SISMICO POTENCIAL PARA EL VALLE CENTRAL OCCIDENTAL

El estudio geológico estructural y morfotectónico de la región de la región al norte de la ciudad de Alajuela, muestra una serie de fallas, estructuras volcánicas y alineamientos que pueden ser correlacionados con el terremoto de 1888, o bien, ser nuevas fuentes sísmicas, siendo la falla de Alajuela la alternativa más viable para el origen del terremoto y una depresión 1.5 km al este de Fraijanes, la probable área epicentral.  Los datos obtenidos de los informes y periódicos de la época permiten estimar el patrón de distribución de las isosistas del terremoto del  30 de diciembre de 1888 y calcular junto con otros datos microsísmicos y a partir de relaciones empíricas, los parámetros sísimicos (profundidad, epicentro, magnitud, intensidad, aceleración).  El terremoto de Fraijanes demostró hace casi un siglo ser muy destructivo, y hoy día con el aumento de población e infraestructura en la región, el grado de vulnerabilidad es mayor y por consiguiente aumento el riesgo sísmico.

LA SUSCEPTIBILIDAD A LA INESTABILIDAD DE LADERAS EN LA ZONA NORTE DE ALAJUELA Y EL TERREMOTO DE FRAIJANES DE 1888. EFECTOS Y PREVISIÓN

El terremoto de Fraijanes de 1888 (30 de diciembre), con una magnitud moderada (5.0  M 6.5)  generó una serie de deslizamientos que afectaron los caminos vecinales, viviendas, potreros, zonas de cultivo y aun las áreas de bosques, ríos y quebradas.  El deslizamiento más grande fue el que originó la Laguna de Fraijanes y para la cual proponemos su mecanismo de falla.   Examinando el relieve relativo, las características geológico-geomorfológicas, así como los deslizamientos identificables de la región, se ha obtenido un mapa de susceptibilidad a la inestabilidad de laderas.  Lo anterior permite delimitar zonas de diferente susceptibilidad, las cuales manifiestan diferente aptitud a la construcción de urbanizaciones, obras civiles, etc; así como la necesidad de realización de estudios geotécnicos para su correcto diseño.

EFECTIVIDAD DE LA METODOLOGÍA MORA-VAHRSON MODIFICADA EN EL CASO DE LOS DESLIZAMIENTOS PROVOCADOS POR EL TERREMOTO DE CINCHONA, COSTA RICA

Uno de  los primeros pasos en  la gestión de riesgos por deslizamiento es  la determinación de  las zonas de amenaza, para esto existen una serie de modelos, cada cual con un nivel de complejidad y detalle, cuya selección dependerá del tipo y calidad de datos disponibles en cada región, así como de utilidad de la información generada para el tomador de decisiones. Uno de los modelos más am-pliamente utilizados en la región centroamericana es denominado Método Mora-Vahrson, del cual se analizaran ex-poste al terremoto de Cinchona, con la finalidad de valorar su precisión, en virtud de su simplicidad y fácil aplicación.

Reflection on the 'Landscapes of Rights' Conference, Adelaide, 2009

This article presents a reflective view of three teaching colleagues from Queensland University of Technology, Brisbane who had attended and participated in the 'Landscapes of Rights' Conference in Adelaide, July 2009. The conference is a biennial event run by the Reggio Emilia-Australia Information Exchange. The authors explore and reflect on the provocations posed throughout this conference and consider these in light of their ongoing work in the field of teacher education, of early childhood teaching and as active supporters of children's rights.

QUT speaker identity verification system for EVALITA 2009

This document outlines the system submitted by the Speech and Audio Research Laboratory at the Queensland University of Technology (QUT) for the Speaker Identity Verication: Application task of EVALITA 2009. This submission consisted of a score-level fusion of three component systems, a joint-factor GMM system and two SVM systems using GLDS and GMM supervector kernels. Development and evaluation results are presented, demonstrating the effectiveness of this fused system approach.

The validity and structure of culture-level personality scores: Data from ratings of young adolescents

We examined properties of culture-level personality traits in ratings of targets (N=5,109) ages 12 to 17 in 24 cultures. Aggregate scores were generalizable across gender, age, and relationship groups and showed convergence with culture-level scores from previous studies of self-reports and observer ratings of adults, but they were unrelated to national character stereotypes. Trait profiles also showed cross-study agreement within most cultures, 8 of which had not previously been studied. Multidimensional scaling showed that Western and non-Western cultures clustered along a dimension related to Extraversion. A culture-level factor analysis replicated earlier findings of a broad Extraversion factor but generally resembled the factor structure found in individuals. Continued analysis of aggregate personality scores is warranted.

O'Neill Building Nudgee College

This project involved the complete refurbishment and extension of a 1980’s two-storey domestic brick building, previously used as a Boarding House (Class 3), into Middle School facilities (Class 9b) on a heritage listed site at Nudgee College secondary school, Brisbane. The building now accommodates 12 technologically advanced classrooms, computer lab and learning support rooms, tuckshop, art room, mini library/reading/stage area, dedicated work areas for science and large projects with access to water on both floors, staff facilities and an undercover play area suitable for assemblies and presentations. The project was based on a Reggio Emilia approach, in which the organisation of the physical environment is referred to as the child’s third teacher, creating opportunities for complex, varied, sustained and changing relationships between people and ideas. Classrooms open to a communal centre piazza and are integrated with the rest of the school and the school with the surrounding community. In order to achieve this linkage of the building with the overall masterplan of the site, a key strategy of the internal planning was to orientate teaching areas around a well defined active circulation space that breaks out of the building form to legibly define the new access points to the building and connect up to the pathway network of the campus. The width of the building allowed for classrooms and a generous corridor that has become ‘breakout’ teaching areas for art, IT, and small group activities. Large sliding glass walls allow teachers to maintain supervision of students across all areas and allow maximum light penetration through small domestic window openings into the deep and low-height spaces. The building was also designed with an effort to uphold cultural characteristics from the Edmund Rice Education Charter (2004). Coherent planning is accompanied by a quality fit-out, creating a vibrant and memorable environment in which to deliver the upper primary curriculum. Consistent with the Reggio Emilia approach, materials, expressive of the school’s colours, are used in a contemporary, adventurous manner to create panels of colour useful for massing and defining the ‘breakout’ teaching areas and paths of travel, and storage elements are detailed and arranged to draw attention to their aesthetic features. Modifications were difficult due to the random placement of load bearing walls, minimum ceiling heights, the general standard of finishes and new fire and energy requirements, however the reuse of this building was assessed to be up to 30% cheaper than an equivalent new building, The fit out integrates information technology and services at a level not usually found in primary school facilities. This has been achieved within the existing building fabric through thoughtful detailing and co-ordination with allied disciplines.

Design Minds Tomorrow's Classroom Toolkit

The Design Minds Tomorrow’s Classroom Toolkit was one of six K7-12 secondary school design toolkits commissioned by the State Library of Queensland (SLQ) Asia Pacific Design Library (APDL), to facilitate the delivery of the Stage 1 launch of its Design Minds online platform (www.designminds.org.au) partnership initiative with Queensland Government Arts Queensland and the Smithsonian Cooper-Hewitt National Design Museum, on June 29, 2012. Design Minds toolkits are practical guides, underpinned by a combination of one to three of the Design Minds model phases of ‘Inquire’, ‘Ideate’ and ‘Implement’ (supported by at each stage with structured reflection), to enhance existing school curriculum and empower students with real life design exercises, within the classroom environment. Toolkits directly identify links to Naplan, National Curriculum, C2C and Professional Standards benchmarks, as well as the student capabilities of successful and creative 21st century citizens they seek to engender through design thinking. This toolkit explores, through four distinct exercises, different design tools and ways to approach the future design of environments (classrooms/schools) to facilitate the Reggio Emilia philosophy of learning, while addressing diverse and changing social, cultural, technological and environmental challenges. The Design Minds Tomorrow’s Classroom Toolkit encourages students to explore architecture and interior design, and to think about their (life-long) learning as a product of inspiring interactions with people and the environments around them, and that their potential role in contributing to both delightful and functional design solutions requires a deep understanding of the user experience. More generally, it aims to facilitate awareness in young people, of the role of design in society and the value of design thinking skills in generating strategies to solve basic to complex systemic challenges, as well as to inspire post-secondary pathways and idea generation for education. The toolkit encourages students and teachers to develop sketching, making, communication, presentation and collaboration skills to improve their design process, as well as explore further inquiry (background research) to enhance the ideation exercises. Exercise 1 focuses on the ‘Inquire’ and ‘Ideate’ phases, Exercise 2 on the ‘Inquire’, Exercise 3 builds on ideation skills, and Exercise 4 concentrates on the ‘Implement’ phase. Depending on the intensity of the focus, the unit of work could be developed over a 2-5 week program (approximately 4-10 x 60 minute lessons/workshops) or as smaller workshops treated as discrete learning experiences. The toolkit is available for public download from http://designminds.org.au/tomorrows-classroom/ on the Design Minds website. This toolkit inspired the authorship and facilitation of a 2-day design workshop entitled Learning Environment 2050 at John Paul College, Daisy Hill, Brisbane on the 15-16 August 2013. 120 Grade 7 students and their teachers, under the mentorship of two design academics, 3 QUT design students and a professional architect, as part of a QUT School of Design Project Week community engagement activity, explored the formulation of a participatory design brief for the redesign of the school’s Wesley Precinct (including classrooms, a sustainable farm and recreation areas).

Feasibility of using technology to disseminate evidence to rural nurses and improve patient outcomes

Background: Rural African American women receive less frequent mammography screening and die of breast cancer at a higher rate than is seen in the general population. To overcome this disparity, it is necessary to assist rural providers in their efforts to influence women to obtain screening. Method: This study examined the feasibility of using distance education to disseminate knowledge about timely and appropriate mammography screening to rural nurses, using patient outcome data to evaluate the effectiveness of this intervention. Results: Overall, there was a decline in referrals and mammography screening, but the intervention group centers showed a smaller decline after the educational intervention than did the control group. Conclusion: The findings show the effect of dissemination of information and the feasibility of using patient outcome data for educational evaluation. Neighboring academic health centers and nursing schools should include in their mission the provision of educational programs for relatively isolated rural nurses.

Caught in the act of collaboration: Students’ experiences of collective learning within a real-world design studio context

This study is an evaluation of design students’ perceptions of the benefits of collective learning in a real-world collaborative design studio. Third year students worked in inter-disciplinary teams representing architecture, interior design, landscape architecture, and industrial design. Responding to a real-world brief and in consultation with an industry partner client and early childhood education pre-service teachers, the teams were required to collectively propose a design response for a community-based child and family centre, on an iconic koala sanctuary site. Data were collected using several methods including a participatory action research method, through the form of a large analogue, collaborative jigsaw puzzle. Using a grounded theory methodology, qualitative data were thematically analysed to reveal six distinct aspects of collaboration, which positively impacted the students’ learning experience. The results of this study include recommendations for improving real world collaboration in the design studio in preparation for students’ transition into professional practice.

Understanding Early Childhood Education and Care in Australia: Practices and Perspectives

A foundational text for pre-service teachers explaining the theories, policies and pedagogies that shape the provision of early childhood education and care in Australia. In order to effectively practise as an early childhood educator it is essential to understand the theories, policies and pedagogy that shape the discipline. Understanding Early Childhood Education and Care in Australia provides core foundational knowledge that is critical for best practice. Part One looks at concepts of childhood and the development of mass education before examining influential theories including developmental psychology, sociology, feminisms and critical theory. Specific approaches are also analysed including Reggio Emilia, Montessori, Multiple Intelligences and HighScope. Part Two focuses on the guiding frameworks and policies in Australia and explores in depth issues affecting Indigenous children and provisions for recognising diversity and the practice of inclusion. The final section examines teaching and leadership and considers curriculum, pedagogy and assessment, building relationships between staff and families, the care of babies and infants, the environment in which early childhood education takes place and the responsibilities and professional development of teachers. This essential reference will ensure pre-service teachers develop a sophisticated understanding of how theory underpins effective practice in early childhood education.

Reflecting on Reggio: An evaluation of design intent in an early childhood learning environment

Reggio Emilia is an educational philosophy that encourages teachers, students and their parents to collaborate and actively engage with the environment. This study investigates how the Reggio Emilia design approach was translated architecturally for a kindergarten in an Australian context, and provides insights into the operation of this Reggio kindergarten and the impact that it is now having on the occupants. It evaluates the original architectural design intent of the Reggio Emilia early childhood learning environment against its spatial provision. The relationship that the Reggio Emilia approach facilitates between students and the environment, and the contribution that this approach has on their learning, are also explored. Several key themes emerging from the Reggio values were identified in the literature. These were then used to inform an exploration of the kindergarten spaces and places.. Architects, teachers and a sustainability manager of the kindergarten were interviewed with their experiences constituting the primary data of this study. Using a Grounded Theory methodology, systematic data coding and analysis were then conducted. Themes and concepts that emerged from this process include: differing interpretations of the Reggio Emilia philosophy; motivations for neglect of traditional external structures and play equipment; the impact of education for sustainability; and the positive effects that Reggio Emilia is having on the rest of the institution’s development.
