Edición semántica inteligente de entornos virtuales

Tradicionalmente, los entornos virtuales se han relacionado o vinculado de forma muy estrecha con campos como el diseño de escenarios tridimensionales o los videojuegos; dejando poco margen a poder pensar en sus aplicaciones en otros ámbitos. Sin embargo, estas tendencias pueden cambiar en tanto se demuestre que las aplicaciones y ventajas de estas facilidades software, se pueden extrapolar a su uso en el ámbito de la enseñanza y el aprendizaje. Estas aplicaciones son los conocidos como Entornos Virtuales Inteligentes (EVI); los cuales, tratan de usar un entorno virtual para llevar a cabo labores de enseñanza y tutoría, aportando ventajas como simulación de entornos peligrosos o tutorización personalizada; cosa que no podemos encontrar en la mayoría de los casos de las situaciones de enseñanza reales. Este trabajo trata de dar solución a una de las problemáticas que se plantean a la hora de trabajar con cualquier entorno virtual con el que nos encontremos y prepararlo para su cometido, sobre todo en aquellos enfocados a la enseñanza: dotar de forma automática e inteligente de una semántica propia a cada uno de los objetos que se encuentran en un entorno virtual y almacenar esta información para su posterior consulta o uso para otras tareas. Esto quiere decir que el objetivo principal de este trabajo, es el proceso de recolección de información que se considera importante de los objetos de los entornos virtuales, como pueden ser sus aspectos de la forma, tamaño o color. Aspectos que, por otra parte, son realmente importantes para poder caracterizar los objetos y hacerlos únicos en un entorno virtual donde, a priori, todos los objetos son los mismos a ojos de un ordenador. Este trabajo que puede parecer trivial en un principio, no lo es tanto; y servirá de sustento fundamental para que otras aplicaciones futuras o ya existentes puedan realizar sus tareas. Una de estas tareas pudiera ser la generación de indicaciones en lenguaje natural para guiar a usuarios a localizar objetos en un entorno virtual, como es el caso del proyecto LORO sobre el que se engloba este trabajo. Algunos ejemplos de uso de esta tarea pueden ser desde ayudar a cualquier usuario a encontrar sus llaves en su propia casa a ayudar a un cirujano a localizar cierta herramienta en un quirófano. Para ello, es indispensable conocer la semántica e información relevante de cada uno de los objetos que se presentan en la escena y diferenciarlos claramente del resto. La solución propuesta se trata de una completa aplicación integrada en el motor de videojuegos y escenarios 3D de mayor soporte del mundo como es Unity 3D, el cual se interrelaciona con ontologías para poder guardar la información de los objetos de cada escena. Esto hace que la aplicación tenga una potencial difusión, gracias a las herramientas antes mencionadas para su desarrollo y a que está pensada para tanto el usuario experto como el usuario común.---ABSTRACT---Traditionally, virtual environments have been related to tridimensional design and videogames; leaving a little margin to think about its applications in other fields. However, this tendencies can be changed as soon as it is proven that the applications and advantages of this software can be taken to the learning and teaching environment. This applications are known as intelligent virtual environments, these use the virtual environment to perform teaching and tutoring tasks; tasks we cannot find in most real life teaching situations. This project aims to give a solution to one of the problematics that appears when someone works with any virtual environments we may encounter and prepare it for its duty, mainly those environments dedicated to teaching: automatically and intelligently give its own semantic to the objects that are in any virtual environment and save this information for its posterior query or use in other tasks. The main purpose of this project is the information recollection process that considers the different important facts about the objects that are in the virtual environments, such as their shape, size or color. Facts that are very important for characterizing the objects; to make them unique in the environment where the objects are all the same to the computer’s eye. This project may seem banal in the beginning, but it is not, it will be the fundamental base for future applications. One of this applications may be a natural language indicator generator for guiding users to locate objects in a virtual environment, such as the LORO project, where this project is included. Some examples of the use of this task are: helping any user to find the keys of his house, helping a surgeon to find a tool in an operation room… For this goals, it is very important to know the semantics and the relevant information of each object of the scenario and differentiate each one of them from the rest. The solution for this proposal is a fully integrated application in the videogame and Unity 3D engine that is related to ontologies so it can save the object’s information in every scenario. The previously mentioned tools, as well as the idea that this application is made for an expert user as well as for a common user, make the application more spreadable.

Definición, diseño e implementación de métricas de usuario final sobre componentes web en el lado Front-end, mediante Google Analytics

La web ha evolucionado hacia la participación en la creación de contenido tanto por desarrolladores expertos como por usuarios finales sin un gran conocimiento en esta área. A pesar de que su uso es igual de válido y funcional, las diferencias entre la calidad de los productos desarrollados por ambos puede llegar a ser considerable. Esta característica se observa con mayor claridad cuando se analizan los web components. El trabajo consiste en el desarrollo de un entorno capaz de recoger las métricas de calidad de los componentes, basadas en la interacción con ellos por parte de los usuarios. A partir de las métricas obtenidas, se determinará su calidad para realizar una mejora de la misma, en función de las características valoradas. La selección de las métricas se realiza mediante un estudio de las características que definen a un componente, y permiten ser analizadas. Para poder llevar a cabo la construcción del portal, se ha descrito un prototipo capaz de proporcionar un sistema para permitir que los componentes intercambien información entre ellos. El modelo ha sido integrado en los componentes que se han de evaluar para obtener nuevas métricas sobre esta característica. Se ha desarrollado un dashboard que permite la interacción sin limitaciones de los usuarios con los componentes, facilitándoles un sistema para conectar componentes, utilizando para ello el sistema previamente descrito. Como conclusión del trabajo, se puede observar la necesidad de integrar los componentes web en un entorno real para poder determinar su calidad. Debido a que la calidad está determinada por los usuarios que consumen los componentes, se ha de contar con su opinión en la cuantificación de la misma.---ABSTRACT---Recently, the web has evolved to the collaboration between professional developers and end users with limited knowledge to create web content. Although both solutions are correct and functional, the differences in the quality between them can be appreciable. This feature is shown clearly when the web components are analyzed. The work is composed of the development of a virtual environment which is able to pick the quality measures of the components, based on the interaction between these components and the user. The measures are the starting point to decide the quality, and improve them with the rated measures. The measures selection is done through a study of the main features of a component. This selection can be analyzed. In order to create the website, a prototype has been specified to provide a system in which the components can be trade information between them. The interconnection model has been integrated in the components to evaluate. A dashboard has been developed to allow users interacting with the components without rules, making them possible connecting components through the model. The main conclusion of the work is the necessity of integrating web components in a real environment to decide their quality. Due to the fact that the quality is measured in terms of the rate of the users, it is a must to give them the main roles in the establishment of that quality.

Caracterización geométrica y lumínica de los atrios incorporados en los edificios de Santiago de Chile

El atrio incorporado en los edificios ha sido un recurso espacial que tempranamente se difundió a nivel global, siendo adoptado por las distintas arquitecturas locales en gran parte del mundo. Su masificación estuvo favorecida primero por la rápida evolución de la tecnología del acero y el vidrio, a partir del siglo XIX, y en segundo termino por el posterior desarrollo del hormigón armado. Otro aspecto que explica tal aceptación en la arquitectura contemporánea, es de orden social y radica en la llamativa cavidad del espacio describiendo grandes dimensiones y favoreciendo con ello, el desarrollo de una multiplicidad de usos en su interior que antes eran impensados. Al interior del atrio, la luz natural es clave en las múltiples vivencias que alberga y sea tal vez la condición ambiental más valorada, ya que entrega una sensación de bienestar al conectarnos visualmente con el ambiente natural. Por esta razón de acuerdo al método hipotético deductivo, se evaluaron los efectos de la configuración geométrica, la cubierta y la orientación en el desempeño de la iluminación natural en la planta baja, a partir un modelo extraído desde el inventario de los edificios atrio construidos en Santiago de Chile, en los últimos 30 años que fue desarrollado en el capitulo 2. El análisis cuantitativo de los edificios inventariados se elaboró en el capítulo 3, considerando las dimensiones de los atrios. Simultáneamente fueron clasificados los aspectos constructivos, los materiales y las características del ambiente interior de cada edificio. En esta etapa además, fueron identificadas las variables de estudio de las proporciones geométricas de la cavidad del atrio con los coeficientes de aspecto de las proporciones, en planta (PAR), en corte (SAR) y de la cavidad según (WI), (AR) y (RI). Del análisis de todos estos parámetros se extrajo el modelo de prueba. El enfoque del estudio del capítulo 4 fue la iluminación natural, se revisaron los conceptos y el comportamiento en el atrio, a partir de un modelo físico construido a escala para registro de la iluminancia bajo cielo soleado de la ciudad. Más adelante se construyó el modelo en ambiente virtual, relacionando las variables determinadas por la geometría de la cavidad y el cerramiento superior; examinándose de esta manera distintas transparencias, proporciones de apertura, en definitiva se evaluó un progresivo cerramiento de las aberturas, verificando el ingreso de la luz y disponibilidad a nivel de piso con la finalidad, de proveer lineamientos útiles en una primera etapa del diseño arquitectónico. Para el análisis de la iluminación natural se revisaron diferentes métodos de cálculo con el propósito de evaluar los niveles de iluminancia en un plano horizontal al interior del atrio. El primero de ellos fue el Factor de Luz Día (FLD) que corresponde, a la proporción de la iluminancia en un punto de evaluación interior respecto, la cantidad proveniente del exterior bajo cielo nublado, a partir de la cual se obtuvo resultados que revelaron la alta luminosidad del cielo nublado de la ciudad. Además fueron evaluadas las recientes métricas dinámicas que dan cuenta, de la cantidad de horas en las cuales de acuerdo a los extensos registros meteorológico de la ciudad, permitieron obtener el porcentajes de horas dentro de las cuales se cumplió el estándar de iluminancia requerido, llamado autonomía lumínica (DA) o mejor aún se permanece dentro de un rango de comodidad visual en el interior del atrio referido a la iluminancia diurna útil (UDI). En el Capítulo 5 se exponen los criterios aplicados al modelo de estudio y cada una de las variantes de análisis, además se profundizó en los antecedentes y procedencia de las fuentes de los registros climáticos utilizados en las simulaciones llevadas a cabo en el programa Daysim operado por Radiance. Que permitieron evaluar el desempeño lumínico y la precisión, de cada uno de los resultados para comprobar la disponibilidad de iluminación natural a través de una matriz. En una etapa posterior se discutieron los resultados, mediante la comparación de los datos logrados según cada una de las metodologías de simulación aplicada. Finalmente se expusieron las conclusiones y futuras lineas de trabajo, las primeras respecto el dominio del atrio de cuatro caras, la incidencia del control de cerramiento de la cubierta y la relación establecida con la altura; indicando en lo específico que las mediciones de iluminancia bajo el cielo soleado de verano, permitieron aclarar, el uso de la herramienta de simulación y método basado en el clima local, que debido a su reciente desarrollo, orienta a futuras líneas de trabajo profundizando en la evaluación dinámica de la iluminancia contrastado con monitorización de casos. ABSTRACT Atriums incorporated into buildings have been a spatial resource that quickly spread throughout the globe, being adopted by several local architecture methods in several places. Their widespread increase was highly favored, in the first place, with the rapid evolution of steel and glass technologies since the nineteen century, and, in second place, by the following development of reinforced concrete. Another issue that explains this success into contemporary architecture is associated with the social approach, and it resides in the impressive cavity that describes vast dimensions, allowing the development of multiple uses in its interior that had never been considered before. Inside the atrium, daylight it is a key element in the many experiences that involves and it is possibly the most relevant environmental factor, since it radiates a feeling of well-being by uniting us visually with the natural environment. It is because of this reason that, following the hypothetical deductive method, the effects in the performance of daylight on the floor plan were evaluated considering the geometric configuration, the deck and orientation factors. This study was based in a model withdrawn from the inventory of atrium buildings that were constructed in Santiago de Chile during the past thirty years, which will be explained later in chapter 2. The quantitative analysis of the inventory of those buildings was elaborated in chapter 3, considering the dimensions of the atriums. Simultaneously, several features such as construction aspects, materials and environmental qualities were identified inside of each building. At this stage, it were identified the variables of the geometric proportions of the atrium’s cavity with the plan aspect ratio of proportions in first plan (PAR), in section (SAR) and cavity according to well index (WI), aspect ratio (AR) and room index (RI). An experimental model was obtained from the analysis of all the mentioned parameters. The main focus of the study developed in chapter 4 is daylight. The atrium’s concept and behavior were analyzed from a physical model built under scale to register the illuminances under clear, sunny sky of the city. Later on, this physical model was built in a virtual environment, connecting the variables determined by the geometry of the cavity and the superior enclosure, allowing the examination of transparencies and opening proportions. To summarize, this stage consisted on evaluating a progressive enclosure of the openings, checking the access of natural light and its availability at the atrium floor, in an effort to provide useful guidelines during the first stage of the architectural design. For the analysis of natural lighting, several calculations methods were used in order to determine the levels of illuminances in a horizontal plane inside of the atrium. The first of these methods is the Daylight Factor (DF), which consists in the proportion of light in an evaluation interior place with the amount of light coming from the outside in a cloudy day. Results determined that the cloudy sky of the city has high levels of luminosity. In addition, the recent dynamic metrics were evaluated which reflects the hours quantity. According to the meteorological records of the city’s climate, the standard of illuminance- a standard measure called Daylight Autonomy (DA) – was met. This is even better when the results stay in the line of visual convenience within the atrium, which is referred to as Useful Daylight Illuminance (UDI). In chapter 5, it was presented the criteria applied to the study model and on each of the variants of the analysis. Moreover, the information of the climate records used for the simulations - carried out in the Daysim program managed by Radiance – are detailed. These simulations allowed the observation of the daylight performance and the accuracy of each of the results to confirm the availability of natural light through a matrix. In a later stage, the results were discussed comparing the collected data in each of the methods of simulation used. Finally, conclusions and further discussion are presented. Overall, the four side atrium’s domain and the effect of the control of the cover’s enclosure. Specifically, the measurements of the daylight under summer’s clear, sunny sky allowing clarifying the use of the simulation tool and the method based on the local climate. This method allows defining new and future lines of work deepening on the dynamic of the light in contrast with the monitoring of the cases.

Diseño y configuración de una red de comunicaciones en un Centro de Contactos - Contact Center

Este proyecto muestra una solución de red para una empresa que presta servicios de Contact Center desde distintas sedes distribuidas geográficamente, utilizando la tecnología de telefonía sobre IP. El objetivo de este proyecto es el de convertirse en una guía de diseño para el despliegue de soluciones de red utilizando los actuales equipos de comunicaciones desarrollados por el fabricante Cisco Systems, Inc., los equipos de seguridad desarrollados por el fabricante Fortinet y los sistemas de telefonía desarrollados por Avaya Inc. y Oracle Corporation, debido a su gran penetración en el mercado y a las aportaciones que cada uno ha realizado en el sector de Contact Center. Para poder proveer interconexión entre las sedes de un Contact Center se procede a la contratación de un acceso a la red MPLS perteneciente a un operador de telecomunicaciones, quien provee conectividad entre las sedes utilizando la tecnología VPN MPLS con dos accesos diversificados entre sí desde cada una de las sedes del Contact Center. El resultado de esta contratación es el aprovechamiento de las ventajas que un operador de telecomunicaciones puede ofrecer a sus clientes, en relación a calidad de servicio, disponibilidad y expansión geográfica. De la misma manera, se definen una serie de criterios o niveles de servicio que aseguran a un Contact Center una comunicación de calidad entre sus sedes, entendiéndose por comunicación de calidad aquella que sea capaz de transmitirse con unos valores mínimos de pérdida de paquetes así como retraso en la transmisión, y una velocidad acorde a la demanda de los servicios de voz y datos. Como parte de la solución, se diseña una conexión redundante a Internet que proporciona acceso a todas las sedes del Contact Center. La solución de conectividad local en cada una de las sedes de un Contact Center se ha diseñado de manera general acorde al volumen de puestos de usuarios y escalabilidad que pueda tener cada una de las sedes. De esta manera se muestran varias opciones asociadas al equipamiento actual que ofrece el fabricante Cisco Systems, Inc.. Como parte de la solución se han definido los criterios de calidad para la elección de los Centros de Datos (Data Center). Un Contact Center tiene conexiones hacia o desde las empresas cliente a las que da servicio y provee de acceso a la red a sus tele-trabajadores. Este requerimiento junto con el acceso y servicios publicados en Internet necesita una infraestructura de seguridad. Este hecho da lugar al diseño de una solución que unifica todas las conexiones bajo una única infraestructura, dividiendo de manera lógica o virtual cada uno de los servicios. De la misma manera, se ha definido la utilización de protocolos como 802.1X para evitar accesos no autorizados a la red del Contact Center. La solución de voz elegida es heterogénea y capaz de soportar los protocolos de señalización más conocidos (SIP y H.323). De esta manera se busca tener la máxima flexibilidad para establecer enlaces de voz sobre IP (Trunk IP) con proveedores y clientes. Esto se logra gracias a la utilización de SBCs y a una infraestructura interna de voz basada en el fabricante Avaya Inc. Los sistemas de VoIP en un Contact Center son los elementos clave para poder realizar la prestación del servicio; por esta razón se elige una solución redundada bajo un entorno virtual. Esta solución permite desplegar el sistema de VoIP desde cualquiera de los Data Center del Contact Center. La solución llevada a cabo en este proyecto está principalmente basada en mi experiencia laboral adquirida durante los últimos siete años en el departamento de comunicaciones de una empresa de Contact Center. He tenido en cuenta los principales requerimientos que exigen hoy en día la mayor parte de empresas que desean contratar un servicio de Contact Center. Este proyecto está dividido en cuatro capítulos. El primer capítulo es una introducción donde se explican los principales escenarios de negocio y áreas técnicas necesarias para la prestación de servicios de Contact Center. El segundo capítulo describe de manera resumida, las principales tecnologías y protocolos que serán utilizados para llevar a cabo el diseño de la solución técnica de creación de una red de comunicaciones para una empresa de Contact Center. En el tercer capítulo se expone la solución técnica necesaria para permitir que una empresa de Contact Center preste sus servicios desde distintas ubicaciones distribuidas geográficamente, utilizando dos Data Centers donde se centralizan las aplicaciones de voz y datos. Finalmente, en el cuarto capítulo se presentan las conclusiones obtenidas tras la elaboración de la presente memoria, así como una propuesta de trabajos futuros, que permitirían junto con el proyecto actual, realizar una solución técnica completa incluyendo otras áreas tecnológicas necesarias en una empresa de Contact Center. Todas las ilustraciones y tablas de este proyecto son de elaboración propia a partir de mi experiencia profesional y de la información obtenida en diversos formatos de la bibliografía consultada, excepto en los casos en los que la fuente es mencionada. ABSTRACT This project shows a network solution for a company that provides Contact Center services from different locations geographically distributed, using the Telephone over Internet Protocol (ToIP) technology. The goal of this project is to become a design guide for performing network solutions using current communications equipment developed by the manufacturer Cisco Systems, Inc., firewalls developed by the manufacturer Fortinet and telephone systems developed by Avaya Inc. and Oracle Corporation, due to their great market reputation and their contributions that each one has made in the field of Contact Center. In order to provide interconnection between its different sites, the Contact Center needs to hire the services of a telecommunications’ operator, who will use the VPN MPLS technology, with two diversified access from each Contact Center’s site. The result of this hiring is the advantage of the benefits that a telecommunications operator can offer to its customers, regarding quality of service, availability and geographical expansion. Likewise, Service Level Agreement (SLA) has to be defined to ensure the Contact Center quality communication between their sites. A quality communication is understood as a communication that is capable of being transmitted with minimum values of packet loss and transmission delays, and a speed according to the demand for its voice and data services. As part of the solution, a redundant Internet connection has to be designed to provide access to every Contact Center’s site. The local connectivity solution in each of the Contact Center’s sites has to be designed according to its volume of users and scalability that each one may have. Thereby, the manufacturer Cisco Systems, Inc. offers several options associated with the current equipment. As part of the solution, quality criteria are being defined for the choice of the Data Centers. A Contact Center has connections to/from the client companies that provide network access to teleworkers. This requires along the access and services published on the Internet, needs a security infrastructure. Therefore is been created a solution design that unifies all connections under a single infrastructure, dividing each services in a virtual way. Likewise, is been defined the use of protocols, such as 802.1X, to prevent unauthorized access to the Contact Center’s network. The voice solution chosen is heterogeneous and capable of supporting best-known signaling protocols (SIP and H.323) in order to have maximum flexibility to establish links of Voice over IP (IP Trunk) with suppliers and clients. This can be achieved through the use of SBC and an internal voice infrastructure based on Avaya Inc. The VoIP systems in a Contact Center are the key elements to be able to provide the service; for this reason a redundant solution under virtual environment is been chosen. This solution allows any of the Data Centers to deploy the VoIP system. The solution carried out in this project is mainly based on my own experience acquired during the past seven years in the communications department of a Contact Center company. I have taken into account the main requirements that most companies request nowadays when they hire a Contact Center service. This project is divided into four chapters. The first chapter is an introduction that explains the main business scenarios and technical areas required to provide Contact Center services. The second chapter describes briefly the key technologies and protocols that will be used to carry out the design of the technical solution for the creation of a communications network in a Contact Center company. The third chapter shows a technical solution required that allows a Contact Center company to provide services from across geographically distributed locations, using two Data Centers where data and voice applications are centralized. Lastly, the fourth chapter includes the conclusions gained after making this project, as well as a future projects proposal, which would allow along the current project, to perform a whole technical solution including other necessary technologic areas in a Contact Center company All illustrations and tables of this project have been made by myself from my professional experience and the information obtained in various formats of the bibliography, except in the cases where the source is indicated.

Death Threat Letters: Allegories of American Authorship in the Age of Terrorism

This dissertation examines novels that use terrorism to allegorize the threatened position of the literary author in contemporary culture. Allegory is a term that has been differently understood over time, but which has consistently been used by writers to articulate and construct their roles as authors. In the novels I look at, the terrorist challenge to authorship results in multiple deployments of allegory, each differently illustrating the way that allegory is used and authorship constructed in the contemporary American novel. Don DeLillo’s Mao II (1991), first puts terrorists and authors in an oppositional pairing. The terrorist’s ability to traffic in spectacle is presented as indicative of the author’s fading importance in contemporary culture and it is one way that terrorism allegorizes threats to authorship. In Philip Roth’s Operation Shylock (1993), the allegorical pairing is between the text of the novel and outside texts – newspaper reports, legal cases, etc. – that the novel references and adapts in order to bolster its own narrative authority. Richard Powers’s Plowing the Dark (1999) pairs the story of an imprisoned hostage, craving a single book, with employees of a tech firm who are creating interactive, virtual reality artworks. Focusing on the reader’s experience, Powers’s novel posits a form of authorship that the reader can take into consideration, but which does not seek to control the experience of the text. Finally, I look at two of Paul Auster’s twenty-first century novels, Travels in the Scriptorium (2007) and Man in the Dark (2008), to suggest that the relationship between representations of authors and terrorists changed after 9/11. Auster’s author-figures forward an ethics of authorship whereby novels can use narrative to buffer readers against the portrayal of violent acts in a culture that is suffused with traumatizing imagery.

The programming language python in earth system simulations

-scale vary from a planetary scale and million years for convection problems to 100km and 10 years for fault systems simulations. Various techniques are in use to deal with the time dependency (e.g. Crank-Nicholson), with the non-linearity (e.g. Newton-Raphson) and weakly coupled equations (e.g. non-linear Gauss-Seidel). Besides these high-level solution algorithms discretization methods (e.g. finite element method (FEM), boundary element method (BEM)) are used to deal with spatial derivatives. Typically, large-scale, three dimensional meshes are required to resolve geometrical complexity (e.g. in the case of fault systems) or features in the solution (e.g. in mantel convection simulations). The modelling environment escript allows the rapid implementation of new physics as required for the development of simulation codes in earth sciences. Its main object is to provide a programming language, where the user can define new models and rapidly develop high-level solution algorithms. The current implementation is linked with the finite element package finley as a PDE solver. However, the design is open and other discretization technologies such as finite differences and boundary element methods could be included. escript is implemented as an extension of the interactive programming environment python (see www.python.org). Key concepts introduced are Data objects, which are holding values on nodes or elements of the finite element mesh, and linearPDE objects, which are defining linear partial differential equations to be solved by the underlying discretization technology. In this paper we will show the basic concepts of escript and will show how escript is used to implement a simulation code for interacting fault systems. We will show some results of large-scale, parallel simulations on an SGI Altix system.

REPRESENTAÇÕES SOCIAIS DOS ALUNOS DO PROGRAMA ESPECIAL DE FORMAÇÃO PEDAGÓGICA: UM ESTUDO SOBRE A FORMAÇÃO DOCENTE DE PROFESSORES, QUE JÁ SÃO PROFESSORES

O objetivo desta pesquisa é investigar o Programa Especial de Formação Pedagógica (PEFP), na perspectiva das representações sociais. Foram convidados a participar da pesquisa 463 (quatrocentos e sessenta e três) alunos, integrantes de cinco turmas do curso, sendo que 102 (cento e dois) alunos aceitaram e responderam voluntariamente ao questionário colocado no ambiente virtual de aprendizagem. Em seguida, foram selecionados entre os alunos respondentes, aqueles que já exerciam a docência. Esses professores foram convidados a participar de uma entrevista sobre sua formação docente, por meio do programa especial e 9 (nove) professores aceitaram. Também foram entrevistados 4 (quatro) diretores de escolas e supervisores de ensino que atuam ou atuaram na região metropolitana de Santos. A investigação se completou com a análise da legislação educacional e mandados judiciais referentes ao Programa Especial de Formação Pedagógica. Os dados obtidos foram analisados pelo software ALCESTE e por meio de Análise de Conteúdo, numa metodologia de pesquisa qualitativa. Os resultados apontaram a seguinte representação social: ser professor é ter formação pedagógica, formação profissional e formação acadêmica, por meio de uma licenciatura. Esta representação quanto à formação docente converge para a themata: ser professor é ser licenciado. A díade licenciado/não licenciado enuncia uma tensão existente no centro da representação identificada. Alunos e egressos do curso manifestaram insegurança sobre a legitimidade da licenciatura obtida por meio da complementação pedagógica e, consequentemente, sobre sua inserção profissional no sistema educacional. Entretanto, entrevistas feitas com supervisores de ensino e diretores de escola mostram o outro lado da formação pedagógica, por meio do PEFP. Os relatos dos diretores e supervisores de ensino apontam para a legitimação do curso e para o envolvimento profissional destes professores, nas escolas onde atuam.

A RELAÇÃO PEDAGÓGICA NA TUTORIA A DISTÂNCIA: UM ESTUDO A PARTIR DO CURSO DE PEDAGOGIA

O presente estudo de natureza qualitativa tem por objetivo explicitar as implicações da relação pedagógica com a construção do conhecimento na tutoria à distância com foco nas relações entre professores tutores e alunos da EAD da Universidade Metodista de São Paulo. Analisa a complexidade que envolve o trabalho educativo em ambiente virtual de aprendizagem e a relação estabelecida entre esses sujeitos na prática pedagógica. A partir dos pressupostos metodológicos e das abordagens multirreferencial, dialógica e transpessoal observadas sob a perspectiva da modalidade a distância na construção dos referenciais teóricos. Realizada na UMESP e no polo regional de apoio presencial Mauá-SP, a pesquisa foi desenvolvida por meio de observações, questionários exploratórios e entrevistas de aprofundamento, contou com a participação de quatro professoras tutoras do curso de Pedagogia a distância e dez alunas desse mesmo curso, além da leitura crítica de documentos, considerando a legislação educacional e diretrizes curriculares vigentes. Procurou responder aos seguintes questionamentos: O que é a relação pedagógica? Qual a importância da relação pedagógica quando a concepção educativa assumida trabalha na perspectiva de educar na/para a inteireza? Quais as possibilidades, as dificuldades e limites desta proposta de relação pedagógica na EAD considerando as relações entre professores tutores e alunos? Buscando identificar os conflitos e desafios vividos e experimentados nessa relação, foram problematizados alguns intervenientes no processo de ensino e aprendizagem para a construção do conhecimento na modalidade, desvelando características do discurso e das práticas repletas de sentido e significados. A pesquisa permitiu concluir que, apesar da distância, o aluno não está isolado, ele tem a possibilidade de participar ativamente junto a tutoria na construção de seu conhecimento e de sua formação, essa interação, no entanto, é influenciada pela relação pedagógica entre esses sujeitos e por demais fatores que podem afetar o desenvolvimento do trabalho na educação a distância. Para educar na inteireza, é necessário reconhecer a complexidade presente em todo ato educativo e o caráter da pluralidade, do multiculturalismo e da diversidade presente no contexto da realidade brasileira, bem como a emergência de autoconhecimento e formação continuada para professores na área.(AU)

Spatially structured cognitve models of semantic information:the implications for computerised databases

Existing theories of semantic cognition propose models of cognitive processing occurring in a conceptual space, where ‘meaning’ is derived from the spatial relationships between concepts’ mapped locations within the space. Information visualisation is a growing area of research within the field of information retrieval, and methods for presenting database contents visually in the form of spatial data management systems (SDMSs) are being developed. This thesis combined these two areas of research to investigate the benefits associated with employing spatial-semantic mapping (documents represented as objects in two- and three-dimensional virtual environments are proximally mapped dependent on the semantic similarity of their content) as a tool for improving retrieval performance and navigational efficiency when browsing for information within such systems. Positive effects associated with the quality of document mapping were observed; improved retrieval performance and browsing behaviour were witnessed when mapping was optimal. It was also shown using a third dimension for virtual environment (VE) presentation provides sufficient additional information regarding the semantic structure of the environment that performance is increased in comparison to using two-dimensions for mapping. A model that describes the relationship between retrieval performance and browsing behaviour was proposed on the basis of findings. Individual differences were not found to have any observable influence on retrieval performance or browsing behaviour when mapping quality was good. The findings from this work have implications for both cognitive modelling of semantic information, and for designing and testing information visualisation systems. These implications are discussed in the conclusions of this work.

EFFECTS OF A VISUAL HORIZON ON DROSOPHILA MELANOGASTER OBJECT-TRACKING RESPONSES

To navigate effectively in three-dimensional space, flying insects must approximate distances to nearby objects. Humans are able to use an array of cues to guide depth perception in the visual world. However, some of these cues are not available to insects that are constrained by their rigid eyes and relatively small body size. Flying fruit flies can use motion parallax to gauge the distance of nearby objects, but using this cue becomes a less effective strategy as objects become more remote. Humans are able to infer depth across far distances by comparing the angular distance of an object to the horizon. This study tested if flying fruit flies, like humans, use the relative position of the horizon as a depth cue. Fruit flies in tethered flight were stimulated with a virtual environment that displayed vertical bars of varying elevation relative to a horizon, and their tracking responses were recorded. This study showed that tracking responses of the flies were strongly increased by reducing the apparent elevation of the bar against the horizon, indicating that fruit flies may be able to assess the distance of far off objects in the natural world by comparing them against a visual horizon.

O canto dos vestibulandos em 140 caracteres: linguagem e construção de identidades no Twitter

The revolution caused by the internet and its various social networks eventually bring forth fruitful reflections on cyberculture and the power of identity construction. What seemed purely fashion has become way of being, representation of self, reality creation (Lévy, 1996). Considering language as a social phenomenon, which occurs through interaction, as explicit in Bakhtin (1929), the speech aired on social networks shapes the profile of their users, constructing identities which, according to Hall (2006), are multiple and non-permanent . This research seeks to examine the use of Twitter by school students, developing a reflection on the construction of their own identities in cyberspace. The subjects are students of Educandário Nossa Senhora das Vitórias, private school in Assú/RN, all graduates from high school. Understanding the Vestibular year as a decisive and a reflection engine ever present about their condition of students, subjects eventually express their anxieties, fears and perspectives in the virtual environment, providing us with enough material to analyze how they are high school students, expectations for appropriate selection processes, plus several representations belonging to the school environment. From the discourse conveyed on Twitter expressed in Featured posts, this study reveals the identities of high school students that emerge from it, which led the cast of some evidence. From them, despite the multiplicity of identities observed, presented some common aspects that corroborate the requirements provided for specific objectives, such as: feeling of belonging to a group - class and school; change of routine and behavior towards education; desecration of traditional teaching practices; changing the identity of students'writings. The analysis of postings enables us to know the perceptions of students regarding the school, the disciplines , the pace of studies, interest in school practices, and from such evidence, the perception of how vestibular modify your daily life and a fondness their identities as school students.
