Assessing Electromyographic Interfaces

Electronic apppliances are increasingly a part of our everyday lives. In particular, mobile devices, with their reduced dimensions with power rivaling desktop computers, have substantially augmented our communication abilities offering instant availability, anywhere, to everyone. These devices have become essential for human communication but also include a more comprehensive tool set to support productivity and leisure applications. However, the many applications commonly available are not adapted to people with special needs. Rather, most popular devices are targeted at teenagers or young adults with excellent eyesight and coordination. What is worse, most of the commonly used assistive control interfaces are not available in a mobile environment where user's position, accommodation and capacities can vary even widely. To try and address people with special needs new approaches and techniques are sorely needed. This paper presents a control interface to allow tetraplegic users to interact with electronic devices. Our method uses myographic information (Electromyography or EMG) collected from residually controlled body areas. User evaluations validate electromyography as a daily wearable interface. In particular our results show that EMG can be used even in mobility contexts.

Ordinary Families -Extraordinary Care Giving

Children with severe emotional problems often have multiple needs that require disparate services including child welfare, juvenile justice, health, mental health, substance abuse, and mental retardation (Stroul, 1996). However, the primary care giving responsibilities for these youngsters still remain with their families. It is the family who shelters and clothes them; provides guidance, affection, recreation, nurturing; gets them to appointments with doctors and therapists and to school dayin- and-day-out, year after year (Lourie, 1995). Despite the invaluable and irreplaceable care provided by families, they are often maligned by a system which characterizes them as having their own problems and inadequacies. The purpose of this research is to learn more about the strengths of families who care for children with severe emotional disabilities (SED). This exploratory descriptive study made use of focus groups attended by parents who are caring for such children. In order to improve services to these families, it is important that we understand how the notion of strengths play out in their everyday lives. Observations are made about the care giving plan, which all families devise in the course of caring for their child with special needs. Implications for paid professionals who serve these families are offered by presenting a model for putting family care givers at the hub of the service provision wheel.

Stress and coping in African American grandparents who are raising grandchildren

Over the years, substantial increases have occurred in the number of children being raised by their grandparents. A small number of studies have reported that grandparents raising grandchildren experience an increase in stress due to the demands of caregiving. The primary objectives of this study were to: (1) determine the degree of stress in African American (AA) grandparents who are raising their grandchildren age 12 years or younger; (2) identify the variables pertaining to the demographic characteristics of the grandparent caregiver and characteristics of the caregiving situation; (3) identify the coping strategies reported by AA grandparents; and (4) identify the relative importance of demographic and situational variables pertaining to the grandparent caregiver and caregiving situation, and coping strategies in influencing the degree of stress experienced. ^ An exploratory, descriptive, cross sectional design was used to study stress and coping in 50 AA grandparents who ranged in age from 44–87 years (M = 63.12). Data were collected via one personal interview in January/February 2001 at area senior centers or churches which the grandparent attends in Harris County, Texas. Five home interviews were done as requested by grandparents. ^ The instruments used to measure stress and coping were the Parenting Stress Index developed by Abidin and Folkman and Lazarus' Ways of Coping Questionnaire. Results of the study found that the grandparents is this study were a highly stressed group. Ninety-four percent of the sample demonstrated a “clinically significant” level of stress. Situational variables associated with lower stress levels were use of counseling, use of special school programs such as tutoring and special education, and increased length of caregiving (>5 years). ^ The most frequently used coping strategies overall were seeking social support and positive reappraisal. Six coping strategies were significantly correlated to lower reported stress: positive reappraisal, accepting responsibility, confrontive coping, self-control, planful problem solving, and distancing. ^ The findings from this study have limited generalizability. Nonetheless, this study was useful in adding to the limited amount of literature on AA grandparents who are rearing their grandchildren. The results clearly suggest the need for affordable counseling, support groups, education related to available resources, stress management, and interventions that increase the use of coping strategies found to reduce perceived stress. Future research should investigate levels of stress in AA and other grandparent caregivers longitudinally, as well as focus on stress and coping in grandparents raising grandchildren with special needs. ^

Symposium for dental treatment of medically complex children: Practice based culminating experience a continuing education course

The purpose of this Continuing Education Course is to provide oral health professionals with information to address the unique dental needs of medically complex children. The objective is to train dentists to treat special needs patients so these children have more access to oral healthcare. ^ Under the auspice of Dell Children Hospital of Austin, Lisa Jacob DDS MS is administering this Continuing Education Course for dentists and dental staff from the 46 counties of central Texas served by the hospital.^ Needs assessment was determined through a survey questionnaire to collect data about the number of special needs patients seen by general dentists in Central Texas.^ In recent years, an increasing number of continuing education courses have been developed to help dentists learn techniques for providing dentistry in more understanding ways to patients with special needs. Dentists and dental staff are trained to provide care specifically in dentistry, regardless of who the patient is. This means dentists can perform a clinical examination, carry out procedures to diagnose and treat oral diseases, and provide restorations such as fillings and crowns. ^ Four prominent speakers will provide an instructional tool to address the need for dentists to increase their competence and comfort level in caring for individuals with developmental disabilities. Each speaker will address one of the most frequently encountered cases of medically complex children. The four topics selected by Dr. Lisa Jacob are Cancer, Mental Disability, Downs Syndrome, and Craniofacial Syndromes.^ The public health implications of this continuing education course are presented in providing dental service to this underserved population. When general dentist turn away patients with special needs because of lack of knowledge to treat them, these patients will, more than likely, postpone or abandon needed dental visits because of difficulties reaching pediatric dentists who may not be available in certain areas.^

Specialized managed care for children with cystic fibrosis: Resource use patterns and rate design for a high cost Medicaid population

Objective. This research study had two goals: (1) to describe resource consumption patterns for Medi-Cal children with cystic fibrosis, and (2) to explore the feasibility from a rate design perspective of developing specialized managed care plans for such a special needs population.^ Background. Children with special health care needs (CSHN) comprise about 2% of the California Medicaid pediatric population. CSHN have rare but serious health problems, such as cystic fibrosis. Medicaid programs, including Medi-Cal, are enrolling more and more beneficiaries in managed care to control costs. CSHN, however, do not fit the wellness model underlying most managed care plans. Child health advocates believe that both efficiency and quality will suffer if CSHN are removed from regionalized special care centers and scattered among general purpose plans. They believe that CSHN should be "carved out" from enrollment in general plans. One alternative is the Specialized Managed Care Plan, tailored for CSHN.^ Methods. The study population consisted of children under age 21 with CF who were eligible for Medi-Cal and California Children's Services program (CCS) during 1991. Health Care Financing Administration (HCFA) Medicaid Tape-to-Tape data were analyzed as part of a California Children's Hospital Association (CCHA) project.^ Results. Mean Medi-Cal expenditures per month enrolled were $2,302 for 457 CF children, compared to about \$1,270 for all 47,000 CCS special needs children and roughly $60 for almost 2.6 million ``regular needs'' children. For CF children, inpatient care (80\%) and outpatient drugs (9\%) were the major cost drivers, with {\it all\/} outpatient visits comprising only 2\% of expenditures. About one-third of CF children were eligible due to AFDC (Aid to Families with Dependent Children). Age group explained about 17\% of all expenditure variation. Regression analysis was used to select the best capitation rate structure (rate cells by age and eligibility group). Sensitivity analysis estimated moderate financial risk for a statewide plan (360 enrollees), but severe risk for single county implementation due to small numbers of children.^ Conclusions. Study results support the carve out of CSHN due to unique expenditure patterns. The Specialized Managed Care Plan concept appears feasible from a rate design perspective given sufficient enrollees. ^

Understanding mental illness in Nigeria: Bringing culture and traditional medicine into mental health policy

One of the major challenges in treating mental illness in Nigeria is that the health care facilities and mental health care professionals are not enough in number or well equipped to handle the burden of mental illness. There are several barriers to treatment for individual Nigerians which include the following: such as the lack of understanding of the root causes of mental illness, lack of financial support to get mental treatment, lack of social support (family, friends, neighbors), the fear of stigmatization concerning being labeled as mentally ill or being in association with the mentally ill, and the consultation of traditional native healers who may be unknowingly prolonging illness, rather than addressing and treating them due to lack of formal education and standardization of their treatments. Another barrier is the non-health nature of the mental health services in Nigeria. Traditional healers are essentially the mental health system. The elderly, women, and children are the most vulnerable groups in times of strife and hardships. Their mental well-being must be taken into account as well as their special needs in times of personal or societal crisis. ^ Nigerian mental health policy is geared toward forming a mental health system, but in actuality only a mental illness care system is the observed result of the policy. The government of Nigeria has drafted a mental health policy, yet its actual implementation into the Nigerian health infrastructure and society waits to be materialized. The limited health legislation or policy implementations tend to favor those who have access to these urban areas and the facilities' health services. Nigerians living in rural areas are at a disadvantage; many of them may not even be aware of services available to help them understand and treat mental illness. Perhaps, government driven health interventions geared toward mental illness in rural areas would reach an underserved Nigerians and Africans in general. Issues with political instability and limited infrastructure often hinder crucial financial resources and legislation from reaching the people that are truly in need of governmental leadership in regards to mental health policy.^ Traditional healers are a severely untapped resource in the treatment of mental illness within the Nigerian population. They are abundant within Nigerian communities and are meeting a real need for the mentally ill. However, much can be done to remove the barriers that prevent the integration of traditional healers within the mental health system and improve the quality of care they administer within the population. Mental illness is almost exclusively coped with through traditional medicine practices. Mobilization and education from each strata of Nigerian society and government as well as input from the medical community can improve how traditional medicine is utilized as a treatment for clinical illness and help alleviate the heavy burden of mental illness in Nigeria. Currently, there is no existing policy making structure for a working mental health system in Nigeria, and traditional healers are not taken into account in any formulation of mental health policy. Advocacy for mental illness is severely inadequate due to fear of stigmatization, with no formally recognized national of regional mental health association.^

Intellectual disability: A quandary for immigration

Current immigration options for individuals with intellectual disabilities do not adequately address their special needs and under existing immigration laws, intellectually disabled adult dependents of United States citizens suffer an excessive burden. This problem causes undue hardship of persons whose families lawfully reside in the United States or have the opportunity to immigrate to the United States. The aim of this review is to examine materials relevant to the issue and answer the question: What are the barriers and pathways for adults with intellectual disability within the family-based preference system under United States immigration law? ^ Adults with intellectual disability are a vulnerable population that often relies upon family members to be their principle caregiver and provide financial support. Under the family-based preference system, the United States has maintained that the reunion of family members with their close relatives promotes the health and welfare of the United States, but a review of the number of findings of inadmissibility due to a mental/physical disorder with associated harmful behavior and the number of waivers granted show otherwise. The lack of reviewability of the decisions made by the Board of Immigration Appeals in addition to the lack of transparency surrounding the immigration process only serve to compound this problem. ^

A modo de figuras de un caleidoscopio: el sujeto de la educación especial en los proyectos institucionales

El presente escrito tiene como propósito reflexionar sobre la formación del sujeto en el ámbito de la escuela especial, a partir del estudio de los mediadores explícitos en los proyectos pedagógicos didácticos que contribuyen a la formación de los alumnos, entendiendo al currículo prescripto como lo más próximo a lo que ocurre en el espacio del aula. La información que se retoma para lograr el propósito de este escrito surge del proceso de análisis e interpretación de los datos extraídos de los proyectos pedagógicos estudiados en cinco escuelas de modalidad especial de la ciudad de Río Cuarto y la región. Entre los conceptos teóricos de relevancia, cobran importancia en el marco de nuestro análisis la propuesta teórica de Cerletti (2008) desde una perspectiva filosófica-política, que considera al sujeto en relación a dos concepciones básicas: el sujeto de la educación y el sujeto en la educación. Retomando la idea de la marca que imprime la pedagogía en la conformación subjetiva de los individuos a partir de los mediadores presentes en la educación del sujeto, se plantea la importancia de que el currículo prescripto conduzca a preguntar por qué los docentes hacemos lo que hacemos, qué enseñamos y para qué, cómo lo enseñamos y que concepción tenemos acerca del cómo formar a nuestros alumnos (Vaisman, 2006).

Acerca de algunas cuestiones invisibilizadas detrás de las Escuelas Inclusivas : de la declaración de los derechos de los niños a la deconstrucción de sus derechos

Este trabajo tiene como propósito problematizar experiencias derivadas de la intención de hacer de las organizaciones escolares -tal como funcionan en la actualidad, “escuelas inclusivas"- de modo de evitar que por esta vía y sin demasiada conciencia al respecto, se continúe avanzando en la profundización de un modelo que –por falta de revisión- corre el riesgo de terminar legitimando prácticas que, en ocasiones, hasta puedan estar contribuyendo a desvirtuar de manera significativa las intenciones y los principios mismos a partir de los cuales se sostienen. Para esto se aportan algunos elementos que contribuyen a visibilizar algunas cuestiones que –a partir de la riqueza que brinda una lectura de carácter interdisciplinaria de las mismas- se observa que se han ido naturalizando, a través de diversas prácticas pedagógicas orientadas a la “inclusión escolar" de niños con necesidades educativas especiales, algunos de cuyos “efectos" parecen –paradójicamente- estar promoviendo, incluso, hasta lo opuesto, es decir, procesos de “exclusión" encubiertos. Entre ellos, se hace referencia al de la “patologización y medicalización de las infancias y adolescencias actuales", a partir del cual se produce una suerte de “inversión" de los procesos de la pretendida “escuela inclusiva".

Competencias de los futuros docentes de educación especial en la escuela inclusiva : la perspectiva de las familas

El artículo que presentamos se trata de una investigación cualitativa que tiene por objetivo analizar la visión de las familias sobre los aspectos que consideran que deben desarrollarse en la formación inicial de los profesionales de Educación Especial que van a trabajar cada día en la inclusión del alumnado con necesidades educativas especiales. Utilizando una metodología cualitativa, realizamos un análisis descriptivo e interpretativo de los resultados obtenidos apoyándonos en un sistema de categorías o dimensiones inductivo con el cual hemos profundizado en los datos personales de las familias, las ideas de los profesionales sobre los niños y niñas, la finalidad de su trabajo con estos, la competencia científica, la competencia intra e interpersonal, la competencia didáctica, la competencia en gestión de la convivencia y la competencia social-relacional. Concluimos que desde la perspectiva de las familias, la relación familia-escuela es el eje fundamental para atender a la diversidad del alumnado teniendo en cuenta las características familiares de cada alumno o alumna y utilizando la información aportada por la misma como enclave básico para el desarrollo del niño o niña.

Traslaciones Poéticas: un recorrido por la Friedrichstrasse de Mies van der Rohe en 1921. Arquitectura, fotografía y cine, la percepción en la arquitectura

El presente ensayo pretende aportar una reflexión sobre el amplio territorio de la imagen en la arquitectura hoy. Para ello un buen ejemplo es el proyecto del Rascacielos de la Friedrichstrasse, realizado por Mies van der Rohe en el periodo de entre guerras de 1921/22. Muchas son las razones que han hecho de esta obra la elegida, pero una más actual sobresale del resto: que de los cientos de ensayos vertidos sobre esta obra solo se haya comentado -salvo alguna excepción- las características objetuales de lo directamente descrito por las vistas -como si fuera un fiel reflejo de la realidad- sin entrar a analizar la verdadera naturaleza física y simbólica de lo representado como expresión subjetiva –espacial- de una arquitectura. Si su importancia como punto de inflexión en el desarrollo inicial de una obra plenamente moderna es un motivo más que suficiente para dedicarle un estudio pormenorizado, ya que puede resultar crucial para comprender los inicios del autor en el Movimiento Moderno. Su presencia como un reducido conjunto de cuatro vistas perspectivas, mezcla de una fotografía del lugar y de un dibujo realizado sobre la misma, acarrea en nuestra opinión significaciones igual de importantes para la comprensión de esta arquitectura que todas aquellas ideas descritas sobre las mismas. Creadas en una época seminal, cuando el lenguaje de la fotografía y el cine están en pleno desarrollo, se puede afirmar que el conjunto de representaciones del Rascacielos de la Friedrichstrasse forman parte como referente histórico de una de las primeras arquitecturas virtuales que pertenecen de pleno derecho al Movimiento Moderno. Paradigma de las más absoluta actualidad, por encontrarse en esa frontera de lo nunca realizado, pero sí asumible espacialmente como realidad fotográfica, las imágenes del rascacielos se pueden considerar así como una de las primeras reflexiones sobre la naturaleza virtual del proyecto arquitectónico postindustrial. No siendo novedoso que la descripción fotográfica de una obra absorba y comunique por sí misma las múltiples propiedades que esta posee, como tampoco lo es que la mayoría de arquitecturas se den por conocidas actualmente a través de los medios. Sorprende que hasta hoy no se hayan analizado con la misma intensidad las múltiples razones que dieron lugar a unas imágenes cuya poética da forma por igual a la arquitectura que representan. Si la intención es reflexionar así sobre este hecho contemporáneo mediante un ejemplo paradigmático, certificado por la historia, nos veremos obligados a emplear una metodología acorde a la condición dual que toda imagen mediatizada produce en su lectura como mezcla fluctuante entre lo que se interpreta de manera autónoma a través de lo representado y de los significados que la imagen adquiere a lo largo de su recorrido como referente histórico. Esta ambivalencia interpretativa llevará a organizar este ensayo mediante dos bloques claramente diferenciados que, complementarios entre sí, siguen el orden de lectura que toda imagen de una arquitectura ofrece a través de los medios. Así, una primera parte, titulada La imagen de una arquitectura, analiza la interpretación que la historia y el autor han dado al rascacielos por medio de su uso en las diferentes exposiciones, revistas, tratados de estilos y monografías de las que ha formado parte. Este recorrido, que es el verdadero espacio donde estas arquitecturas residen, limitado -por una cuestión de poner orden- al estudio a los países que acogieron en vida al autor, servirá para establecer una primera narrativa que expone las diferentes posiciones que la crítica ha producido a lo largo del tiempo. La presencia del primer rascacielos junto al segundo, en la publicación que el arquitecto realiza de manera temprana en Frühlicht, obligará a incorporar esta segunda solución como una parte más del estudio. Cargada de las citas obligadas, de las diferentes personalidades que se han enfrentado a dichos proyectos, este primer análisis historiográfico establece un primer estado de la cuestión donde se revela una lectura ambivalente de los rascacielos. Si la interpretación directa de sus imágenes ha permitido profundizar en las características del vidrio y sus reflejos y en la desnudez de una estructura metálica como claros ejemplos de una expresión moderna y tecnológica de vidrio y el acero. Las particulares formas triangulares del primero y las formas sinuosas del segundo han dado lugar a una multitud de calificaciones, de ser ejemplo tanto de un Expresionismo como de un dadaísmo o constructivismo, que con el tiempo han ido creciendo hacia una admiración artística con una fuerte carga poética. Este lectura histórica, que remata con un breve periodo más actual donde se inicia el cuestionamiento de su carácter utópico y se recupera puntualmente su naturaleza como proyecto, servirá para plantear finalmente una serie de dudas que, sin respuesta aparente, exigen revisar la lectura de sus imágenes como parte de lo que realmente son: expresión de una nueva arquitectura que a partir de ese preciso momento entra de pleno derecho en el Movimiento Moderno. Por otro lado, la existencia en el discurso posterior del arquitecto de un proceso de formalizacion altamente valorado por su autor y la presencia de igual a igual de un lugar en las representaciones y planos de los rascacielos, que la historia parece haber obviado, servirán como razón más que suficiente para la revisión de unas relaciones iniciales con la vanguardia -todavía hoy poco definidas- así como para proponer la lectura renovada de dichas propuestas en altura por lo que también son: proyectos que responden a unas necesidades espaciales de un lugar y tiempo muy determinados. Esta segunda parte, denominada La arquitectura de una imagen, se plantea así más como una inmersión total en el mundo del proyecto que una simple descripción nominal del mismo. Conscientemente simétrica y opuesta a un primer bloque histórico, esta segunda parte -mucho más extensa y parte central de esta tesis- se concentra en el análisis de las imágenes como: aquel conjunto de eventos históricos que aplicados sobre la ciudad, el lugar, el rascacielos, y los procesos técnicos de la imagen dieron lugar a estas arquitecturas como razón de ser. Consecuentemente se tratará pues de bucear en las razones que, ocultas como proceso de formalización, llevaron a Mies a dar un paso más allá hacia a una nueva manera de hacer, ver y pensar su arquitectura, de expresar un espacio. La aproximación a estas imágenes radicará por tanto en resaltar al mismo tiempo la naturaleza de unas representaciones cuyas características fotográficas son el fiel reflejo de una época donde los nuevos medios visuales –cine y fotografía- empiezan a ser cuestionados por su excesiva utilización. La complejidad de unos hechos coincidentes en el tiempo obligará a dividir este estudio en un primer acercamiento general, a la respuesta dada por una mayoría de participantes al concurso, para así cotejar la importancia de una actitud proyectual y contextual común de Mies y sus compañeros. Mezcla de requerimientos y necesidades de la propia historia de la parcela, de las peculiaridades de un lugar y las exigencias programáticas del concurso; el siguiente paso consistirá en reconstruir el proceso de formalización del conjunto de dibujos que caracterizan ambos proyectos para así comprender los mecanismo que, suspendidos como traslaciones entre las diferentes representaciones, operan en la realización física de dichas imágenes y complementan como pensamiento la idea arquitectónica de los mismos. Con lo que se pretende ofrecer dos cosas: una interpretación que tenga en cuenta la novedosa naturaleza de la manera de pensar lo fotográfico en el arquitecto, así como la particular idiosincrasia del momento en que estas concurren. Dicho de otro modo, se realizará una aproximación de las vistas del primer rascacielos que tenga en cuenta la historia tecnológica y visual que rodea al evento y las características de una ejecución física todavía hoy sin aclarar del todo. El descubrimiento de una serie de incoherencias geométricas en las plantas, alzado y vistas del primer proyecto llevará a argumentar la presencia de un trampantojo que, nunca antes revelado, se entiende lleno de unas intenciones espaciales plenamente vanguardistas. Interpretación arquitectónica de las imágenes donde la presencia de una serie de elementos directamente ligados al lenguaje fotográfico y cinematográfico se traduce en una nueva lectura espacial plenamente dinámica llena de dislocación, ritmo y simultaneidad alejada de la idea de ver la forma como un elemento permanentemente fijo. Sugerencia que nos lleva directamente a la lectura del segundo proyecto de rascacielos como una clara continuación de lo imaginado en el primero. Para finalizar, tras una revisión biográfica -previa al proyecto- que desvela unas preocupaciones urbanas y un deseo de cambio anterior al concurso de la Friedrichstrasse, se comparan estas nuevas significaciones espaciales con una práctica de vanguardia que, coetánea a la convocatoria de 1921, demuestran unas investigaciones muy similares con unos mismos intereses cinematográficos. La lectura de las propuestas de tres artistas próximos en ese momento al arquitecto -como son Hans Richter, Moholy-Nagy y El Lissitzky- permiten demostrar unas preocupaciones muy similares a lo conseguido por Mies con los rascacielos que parecen haber servido de ejemplo y motivación mutua para el surgimiento de una nueva espacialidad -más fluida-. Esta lectura permitirá recuperar la importancia de estos dos proyectos como la expresión directa de una nueva manera de pensar y hacer su arquitectura que ya no tendrá vuelta atrás en la obra de Mies. A la vez que recuperar la potencialidad poética de unas vistas que, así definidas reiteradamente por la crítica, se revelan ahora como directas transmisoras de ese deseo de cambio arquitectónico evidenciado en los proyectos posteriores. Racionalización de una poética que al ir más allá de la forma directamente transcrita permite establecer una última reflexión general sobre como opera la imagen en la arquitectura, así como la pertinencia crítica de este proyecto para con el mundo virtual de hoy. En definitiva, más allá del poder evocador de estas representaciones, este será un estudio que pretende cuestionar las características que la imagen de la arquitectura puede proponer más allá de su literalidad por medio de la fascinante interacción que se produce entre la imagen y lo espacialmente imaginado. Encuentros, recursos e intereses de una respuesta plenamente arquitectónica que, además de dar luz a un cambio tan inclasificable como moderno, abre el camino a la interpretación de un proceso de formalizacion que, reiteradamente defendido por su autor justifican una intensidad poética dada por la historia y reafirman una preocupación artística a menudo desmentida por su autor. Dicho de otro modo, si profundizar en las razones arquitectónicas, históricas y técnicas que llevan a Mies a realizar sus rascacielos, por medio de su relación con la vanguardia y el cine, arrojan luz y explican el cambio que se está gestando en el arquitecto cara una nueva espacialidad fluida. Reflexionar sobre su naturaleza espacial -de estas imágenes ya icónicas- equivale a aportar una reflexión crítica sobre la naturaleza simbólica de la imagen de la arquitectura hoy. “Aunque el puesto clave que ocupa el Rascacielos de la Friedrichstrasse dentro de la historia de la arquitectura moderna nunca ha sido seriamente cuestionado, la opinion critica al respecto siempre ha estado dividida. Desde la publicacion de la monografia de Philip Johnson sobre Mies en 1947, el muro cortina como una piel transparente que reviste el esqueleto estructural has ido aclamado como un gran avance pionero. Otros puntos de vista sobre el edificio, subrayando su supuesta planta expresionista, lo han visto como un esfuerzo un poco menos aventurado. Asi calibrada, la propuesta de Mies para la Friedrichstrasse es radicalmente moderna en mas de un sentido enfatizado por Johnson.” 1 W.Tegethoff ABSTRACT This essay reflects on the broad territory of the image in today’s architecture. One good example is the Friedrichstrasse Skyscraper design by Mies van der Rohe in 1921/22, during the period between World Wars I and II. There are many reasons why this work has been chosen, but one of the most recent stands out above the rest: of the hundreds of essays written on this work, comments have been made only (with the odd exception) on the objectual characteristics of what has been directly described by the views (as if it were a genuine reflection of reality), without analysing the real physical and symbolic nature of the representation a subjective (spatial) expression of architecture. If its importance as a point of inflection in the initial development of a completely modern work is more than enough reason to make a detailed study, since it may be crucial for understanding the author’s beginnings in the Modern Movement. Its presence as a reduced set of four views, the combination of a photograph of the place and a drawing made of it, in our opinion, carry meanings that are as important for understanding this architecture as all the ideas described about them. Created during an early period, when the languages of photography and cinema were in full swing, it can be said that the perspectives of the Friedrichstrasse Skyscraper form a historical reference of one of the first virtual architectures that belong entirely to the Modern Movement. A paradigm of the most absolute modernity owing to the fact that it is on that frontier of the never-accomplished, but spatially assumable as photographic reality, the images of the skyscraper can be considered as one of the first reflections on the virtual nature of post-industrial architectural design. There is nothing new in the fact that the photographic description of work absorbs and communicates on its own the multiple properties it involves and there is nothing new in the fact that most architectures become known today through the media. It is surprising that no analysis has been made to date, with the same intensity, of the many reasons that led to a number of images whose poetry add form to the architecture they represent. If the intention is to reflect on this contemporary fact using a paradigmatic example certified by history, we will be forced to use a methodology that corresponds to the dual condition produced by the interpretation of all media images as a fluctuating combination of what is interpreted independently through the representation and meanings the image acquires as a historical reference. This ambivalent interpretation will lead this essay to be structured in two clearly different and complementary blocks that follow the reading order offered by any image of architecture in the media. Thus, a first part, titled The image of an architecture, analyses the interpretation history and the author have given to the skyscraper through its use in the various exhibitions, magazines, style agreements and monographs in which it has been included. This examination, which is the real space in which these architectures reside, is (to delimit and organise the study) restricted to countries in which the author lived during his lifetime and it will help establish a first narrative that considers the different interpretations made by critics over time. The presence of the first skyscraper next to the second one in the publication the architect makes early on in Frühlicht will require the second solution to be incorporated as another part of the study. Laden with necessary quotes by the various personalities who have examined said designs, this first historiographical analysis establishes an initial state of the question that reveals an ambivalent interpretation of skyscrapers. If the direct interpretation of the images has made it possible to closely examine the characteristics of the glass and its reflections and the nudity of a metal structure as clear examples of a modern and technological expression of glass and steel. The particular triangular shapes of the former and the sinuous shapes of the latter have generated many classifications that suggest it is an example of Expressionism, Dadaism or Constructivism, which have grown over time into artistic admiration laden with poetry. This historical reading, which concludes with a more recent short period that begins to question the utopian character and recovers its nature as a project, will finally consider a number of doubts that have no apparent answer and require a revision of the reading of the images as part of what they actually are: expression of a new architecture that becomes part of the Modern Movement as from that precise moment. In addition, the existence in the architect’s subsequent discourse of a formalisation process highly valued by the author and the equal presence of a place in the representations and plans of a skyscraper history seems to have forgotten, will stand as more than sufficient reason for a revision of initial relations with the avantgarde -not particularly well defined today- together with a renewed reading of said vertical proposals for what they also are: projects that respond to the special needs of a very specific place and time. This second part, titled The architecture of an image, is presented more as a total immersion in the project world than a mere nominal description of it. Deliberately symmetrical and opposite to a historic first bloc, this second part (much longer and central part of the thesis) it will focus on analysing images as: the set of historical events that affected the skyscraper, city, place and technical processes image to provide these architectures with their raison d’être. Consequently, the aim is to delve in the reasons which, hidden as a formalisation process, led Mies to move on to a new form of doing, seeing and thinking his architecture, of expressing a space. The approach to these images will therefore lie in highlighting the nature of a number of representations whose photographic features are the true reflection of a period in which the new visual media (cinema and photography) begin to be questioned due to excessive use. The complexity of facts that coincide in time will require this study to be divided into a first general approach, with a response given by most of the participants in the competition, to compare the importance of a common approach in terms of project and context of the response given by Mies and his colleagues. A combination of requirements and needs of the very history of the plot of land, the peculiarities of a place and the programmatic requirements of the competition; the next step will reconstruct the formalisation process of the set of drawings that characterise both to understand the mechanism which, suspended like translations between the different representations, operates in the realisation of said images and complements as thought their architectural idea. The aim is thus to offer two things: an interpretation that takes into account the new way in which the architect works with photography, together with the particular idiosyncrasy of the moment at which they occur. In other words, the approach will focus on the views of the first skyscraper, which takes into account the technological and visual history that surrounds the event and the characteristics of a physical execution that still remains unexplained in full. The subsequent discovery of a number of geometrical incoherences in the floor plans, elevations and views of the first project will lead to an argument for the presence of trompe l’oeil which, never before revealed, is seen as laden with completely avant-garde spatial intentions. Architectural interpretation of the images where the presence of a number of elements directly linked to the languages of photography and cinema is translated into a new spatial reading that is completely dynamic and full of dislocation, rhythm and simultaneity far-removed from the idea of seeing shape as a permanently fixed element. This suggestion takes us to directly to the second skyscraper design as a clear continuation of what he imagined in the first. To end, after a preliminary biographical revision (previous to the project) that reveals urban concerns and a desire for change before the Friedrichstrasse competition, a comparison is made of these new spatial meanings with avant-garde practice which, contemporary with the 1921 competition, show very similar investigations with the same cinematographic interest. The reading of the proposals of three artists close to the architect at that time -i.e. Hans Richter, Moholy-Nagy and El Lissitzky- reveals concerns that are very similar to what Mies achieved with the skyscrapers that seem to have been used as an example and mutual motivation for the creation of a new (more fluent) spatiality. This interpretation will make it possible to recover the importance of these two projects as the direct expression of a new way of thinking and doing his architecture that was to remain fixed in Mies’ work. This also gives rise to the possibility of recovering the poetic potential of views which, as defined repeatedly by the critics, now stand as the direct transmitters of the desire for architectural change shown in later projects. A rationalisation of poetry which, by going beyond the directly transcribed form, gives rise to the establishment of one general final reflection on how the image works in architecture, together with the critical relevance of this design for today’s virtual world. In short, beyond the evocative power of images this will be a study which questions the characteristics the image of architecture can propose beyond its literality through the fascinating interaction between the image and spatially imagined. Encounters, resources and interests of a completely architectural response that, besides sheds light to a change that is as non-classifiable as it is modern, shows the way to the interpretation of a formalisation process which, repeatedly defined by the author, justifies a poetic intensity and confirms an artistic concern often denied by the author. In other words, examining the architectural, historical and technical reasons that led Mies to create his skyscrapers, thanks to its relationship with the avant-garde and cinema, sheds light on and explains the change taking place in the architect with regard to a new fluent spatiality. Reflecting on the spatial nature -of these iconic images- is tantamount to a critical reflection on the symbolic nature of architecture today. “Although the key position of the Friedrichstrasse Office Building within the early history of modern architecture has never been seriously challenged, critical opinion on it has always been divided. Ever since the publication of Philip Johnson’s monograph on Mies in 1947, the curtain wall as a transparent skin sheathing the skeleton structure has frequently been hailed as a pioneering breakthrough. Other views of the building, stressing its supposedly Expressionist plan, have seen it as a somewhat less adventurous effort. In fact, the project has never been regarded in abroad context. Thus measured, Mies’s proposal fro Friedrichstrasse is radically modern in more than the one respect emphasized by Johnson.” 1 W.Tegethoff

Sistema de autenticación accesible para el hogar digital

El Hogar Digital Accesible (HDA) de la ETSIST nace con el propósito de acercar las nuevas Tecnologías de la Información a las personas que precisan de necesidades concretas de accesibilidad y usabilidad, dotándoles de herramientas que les permitan aumentar su calidad de vida, confort, seguridad y autonomía. El entorno del HDA consta de elementos de control para puertas, persianas, iluminación, agua o gas, sensores de temperatura, incendios, gas, sistemas de climatización, sistemas de entretenimiento y sistemas de seguridad tales como detectores de presencia y alarmas. Todo ello apoyado sobre una arquitectura de red que proporciona una pasarela residencial y un acceso a banda ancha. El objetivo principal de este PFG ha sido el desarrollo de un sistema de autenticación para el Hogar Digital Accesible de bajo coste. La idea de integrar un sistema de autenticación en el HDA, surge de la necesidad de proteger de accesos no deseados determinados servicios disponibles dentro de un ámbito privado. Algunos de estos servicios pueden ser tales como el acceso a la lectura de los mensajes disponibles en el contestador automático, el uso de equipos multimedia, la desconexión de alarmas de seguridad o simplemente la configuración de ambientes según el usuario que esté autenticado (intensidad de luz, temperatura de la sala, etc.). En el desarrollo han primado los principios de accesibilidad, usabilidad y seguridad necesarios para la creación de un entorno no invasivo, que permitiera acreditar la identidad del usuario frente al sistema HDA. Se ha planteado como posible solución, un sistema basado en el reconocimiento de un trazo realizado por el usuario. Este trazo se usará como clave de cara a validar a los usuarios. El usuario deberá repetir el trazado que registró en el sistema para autenticarse. Durante la ejecución del presente PFG, se justificará la elección de este mecanismo de autenticación frente a otras alternativas disponibles en el mercado. Para probar la aplicación, se ha podido contar con dos periféricos de distintas gamas, el uDraw creado para la PS3 que se compone de una tableta digitalizadora y un lápiz que permite recoger los trazos realizados por el usuario de forma inalámbrica y la tableta digitalizadora Bamboo de Wacom. La herramienta desarrollada permite a su vez, la posibilidad de ser usada por otro tipo de dispositivos como es el caso del reloj con acelerómetro de 3 ejes de Texas Instruments Chronos eZ430 capaz de trasladar los movimientos del usuario al puntero de un ratón. El PFG se encuentra dividido en tres grandes bloques de flujo de trabajo. El primero se centra en el análisis del sistema y las tecnologías que lo componen, incluyendo los distintos algoritmos disponibles para realizar la autenticación basada en reconocimiento de patrones aplicados a imágenes que mejor se adaptan a las necesidades del usuario. En el segundo bloque se recoge una versión de prueba basada en el análisis y el diseño UML realizado previamente, sobre la que se efectuaron pruebas de concepto y se comprobó la viabilidad del proyecto. El último bloque incluye la verificación y validación del sistema mediante pruebas que certifican que se han alcanzado los niveles de calidad necesarios para la consecución de los objetivos planteados, generando finalmente la documentación necesaria. Como resultado del trabajo realizado, se ha obtenido un sistema que plantea una arquitectura fácilmente ampliable lograda a través del uso de técnicas como la introspección, que permiten separar la lógica de la capa de negocio del código que la implementa, pudiendo de forma simple e intuitiva sustituir código mediante ficheros de configuración, lo que hace que el sistema sea flexible y escalable. Tras la realización del PFG, se puede concluir que el producto final obtenido ha respondido de forma satisfactoria alcanzando los niveles de calidad requeridos, siendo capaz de proporcionar un sistema de autenticación alternativo a los convencionales, manteniendo unas cotas de seguridad elevadas y haciendo de la accesibilidad y el precio sus características más reseñables. ABSTRACT. Accessible Digital Home (HDA) of the ETSIST was created with the aim of bringing the latest information and communications technologies closer to the people who has special needs of accessibility and usability increasing their quality of life, comfort, security and autonomy. The HDA environment has different control elements for doors, blinds, lighting, water or gas, temperature sensors, fire protection systems, gas flashover, air conditioning systems, entertainments systems and security systems such as intruders detectors and alarms. Everything supported by an architecture net which provides a broadband residential services gateway. The main goal of this PFG was the development of a low-cost authentication system for the Accessible Digital Home. The idea of integrating an authentication system on the HDA, stems from the need to safeguard certain private key network resources from unauthorized access. Some of said resources are the access to the answering machine messages, the use of multimedia devices, the alarms deactivation or the parameter settings for each environment as programmed by the authenticated user (light intensity, room temperature, etc.). During the development priority was given to concepts like accessibility, usability and security. All of them necessary to create a non invasive environment that allows the users to certify their identity. A system based on stroke pattern recognition, was considered as a possible solution. This stroke is used as a key to validate users. The user must repeat the stroke that was saved on the system to validate access. The selection of this authentication mechanism among the others available options will be justified during this PFG. Two peripherals with different ranges were used to test the application. One of them was uDraw design for the PS3. It is wireless and is formed by a pen and a drawing tablet that allow us to register the different strokes drawn by the user. The other one was the Wacom Bamboo tablet, that supports the same functionality but with better accuracy. The developed tool allows another kind of peripherals like the 3-axes accelerometer digital wristwatch Texas Instruments Chronos eZ430 capable of transfering user movements to the mouse cursor. The PFG is divided by three big blocks that represent different workflows. The first block is focused on the system analysis and the technologies related to it, including algorithms for image pattern recognition that fits the user's needs. The second block describes how the beta version was developed based on the UML analysis and design previously done. It was tested and the viability of the project was verified. The last block contains the system verification and validation. These processes certify that the requirements have been fulfilled as well as the quality levels needed to reach the planned goals. Finally all the documentation has been produced. As a result of the work, an expandable system has been created, due to the introspection that provides the opportunity to separate the business logic from the code that implements it. With this technique, the code could be replaced throughout configuration files which makes the system flexible and highly scalable. Once the PFG has finished, it must therefore be concluded that the final product has been a success and high levels of quality have been achieved. This authentication tool gives us a low-cost alternative to the conventional ones. The new authentication system remains security levels reasonably high giving particular emphasis to the accessibility and the price.

Aplicación de lectoescritura para dispositivos con Sistema Operativo Android

El presente proyecto pretende ser una herramienta para la enseñanza de la lectoescritura (enseñar a leer y a escribir) para niños con discapacidad, haciendo para ello uso de una aplicación que se ejecuta en una tablet con Sistema Operativo (S.O.) Android. Existe un vacío en el mundo de las aplicaciones para tabletas en este campo en el que se intentará poner un grano de arena para, al menos, tener una aplicación que sirva de toma de contacto a los interesados en este campo. Para establecer las funcionalidades más adecuadas al propósito de la herramienta, se ha consultado a profesionales de la logopedia de un colegio de educación especial, con cuya colaboración se ha dado forma a la estructura de la misma. La implementación de la aplicación se ha llevado a cabo con programación en entorno Java para Android. Se han incluido diferentes recursos como imágenes, pictogramas y locuciones tanto elementos con licencia libre, como elementos propios generados ‘ex profeso’ para dar la forma final a la herramienta. Podemos decir que en general esta aplicación puede ser usada para enseña a leer y escribir a cualquier niño, pero se ha dotado de unas ciertas características que la confieren una orientación especial hacia niños con necesidades educativas especiales. Para ello se ha cuidado mucho la estética, para que ésta sea lo más simple y suave posible, para hacer especial hincapié en la atención de los niños y evitar su distracción con elementos visuales innecesarios. Se ha dotado de estímulos visuales y sonoros para fomentar su interés (aplausos en caso de acierto, colores para diferenciar aciertos y errores, etc.). Se han utilizado los tamaños de letra más grandes posibles (para las discapacidades visuales), etc. El mercado cuenta con una ingente cantidad de dispositivos Android, con características muy dispares, de tamaño de pantalla, resolución y versiones del S.O. entre otras. La aplicación se ha desarrollado tratando de dar cobertura al mayor porcentaje de ellos posible. El requisito mínimo de tamaño de pantalla sería de siete pulgadas. Esta herramienta no tiene demasiado sentido en dispositivos con pantallas menores por las características intrínsecas de la misma. No obstante se ha trabajado también en la configuración para dispositivos pequeños, como “smartphones”, no por su valor como herramienta para la enseñanza de la lectoescritura (aunque en algunos casos podría ser viable) sino más bien con fines de prueba y entrenamiento para profesores, padres o tutores que realizarán la labor docente con dispositivos tablet. Otro de los requisitos, como se ha mencionado, para poder ejecutar la aplicación sería la versión mínima de S.O., por debajo de la cual (versiones muy obsoletas) la aplicación sería inviable. Sirva este proyecto pues para cubrir, mediante el uso de la tecnología, un aspecto de la enseñanza con grandes oportunidades de mejora. ----------------------- This Project is aimed to be a tool for teaching reading and writing skills to handicapped children with an Android application. There are no Android applications available on this field, so it is intended to provide at least one option to take contact with. Speech therapy professionals from a special needs school have been asked for the most suitable functions to be included in this tool. The structure of this tool has been made with the cooperation of these professionals. The implementation of the application has been performed through Java coding for Android. Different resources have been included such as pictures, pictograms and sounds, including free licenses resources and self-developed resources. In general, it can be said that this application can be used to teach learning and writing skills to any given kid, however it has been provided of certain features that makes it ideal for children with special educational needs. It has been strongly taken into account the whole aesthetic to be as simple and soft as possible, in order to get attention of children, excluding any visual disturbing elements. It has been provided with sound and visual stimulations, to attract their interest (applauses in cases of correct answers, different colours to differentiate right or wrong answers), etc. There are many different types of Android devices, with very heterogeneous features regarding their screen size, resolution and O.S. version, etc., available today. The application has been developed trying to cover most of them. Minimum screen resolution is seven inches. This tool doesn’t seem to be very useful for smaller screens, for its inner features. Nevertheless, it has been developed for smaller devices as well, like smartphones, not intended to be a tool for teaching reading and writing skills (even it could be possible in some cases), but in a test and training context for teachers, parents or guardians who do the teaching work with tablet devices. Another requirement, as stated before, in order to be able to run the application, it would be the minimum O.S. version, below that (very obsolete versions) the application would become impracticable. Hope this project to be used to fulfill, by means of technology, one area of teaching with great improvement opportunities.

Teachers’ Use of Inclusive Practices in Spain

The aim of this study was to examine the extent to which teachers use inclusive practices to respond to students’ special needs in their classrooms and to determine whether grade level taught, training, and availability of resources and support affect the implementation of these practices. A research survey was designed for this purpose with the participation of a representative sample of 336 general education teachers (68 kindergarten, 133 elementary, and 135 secondary education teachers) in the province of Alicante, Spain. Findings reflected a moderate use of inclusive practices, with teachers more frequently implementing general adaptations rather than substantial ones. Statistically significant differences in use of inclusive practices were found as a function of the grade level taught, training received, and availability of material resources. Results are discussed in terms of their implication for teacher education reform and training programs.
