Este trabalho teve como objetivo analisar a arborização urbana da Estância Turística de Águas de São Pedro-SP, visando obter uma série de informações que possibilitassem o planejamento de uma cidade com mais qualidade ambiental, mais qualidade de vida para seus habitantes e que se mostrasse mais atrativa aos turistas. Primeiramente, buscou-se quantificar a percepção dos residentes em relação à arborização urbana e ao meio ambiente; para tanto, foram aplicadas 330 entrevistas. Concluiu-se que a maioria da população se referiu à necessidade de melhorias nos parques, nas praças e na arborização urbana, além de apontar problemas ambientais na Estância. Ficando evidente a necessidade de um plano de gestão, que leve em consideração as indicações da opinião pública e os fatores técnicos. Em uma segunda etapa, foi analisado o histórico da formação da cidade e levantadas as condições atuais das praças, dos parques, dos espaços livres e das áreas de preservação permanente. Obtiveram-se os seguintes resultados: a) a cidade possui duas praças e apenas uma é utilizada pela população; b) em relação aos parques, um deles é privado e outros três são de domínio público; destes, um atrai um alto número de freqüentadores e os outros dois são subutilizados. Sugerem-se, então, várias intervenções, que possibilitariam um aumento das atrações turísticas; c) em relação aos espaços livres, não obstante a cidade possuir dois espaços para atrações públicas, a população reclama da falta de lazer. A cidade, além destes, possui mais cinco espaços livres, configurados no projeto de urbanização de uma cidade jardim, mas que ainda não receberam tratamento paisagístico; a maioria se encontra em estado de abandono, sendo um deles propício para a implantação de um parque destinado à recreação infantil, tão desejado pela população, e d) em relação às áreas de preservação permanente, estas se encontram em estado precário e abandonadas, necessitando de intervenções urgentes tanto no uso e ocupação do solo, como em ações de reflorestamento e de tratamento de esgoto. Conclui-se que somente a concepção de um bom projeto urbanístico não garante qualidade ambiental e qualidade de vida aos habitantes de uma cidade; faz-se necessário um planejamento contínuo, que englobe as etapas de concepção, implantação, manutenção e gestão. Na terceira etapa, fez-se uso de videografia aérea multiespectral de alta resolução, obtendo-se a área dos espaços livres, de cobertura de copa, entre outros. Pôde-se concluir, que a técnica foi adequada para a diferenciação dos alvos urbanos e que a cidade possui espaços livres configurados no plano urbanístico de uma cidade jardim, que não estão sendo utilizados, comprometendo a concepção do projeto, acarretando em perdas ambientais, de qualidade de vida e potencial turístico. Constatou-se que o município não tem uma Secretaria do Meio Ambiente, o que reforça a necessidade de sua criação, com ações direcionadas no sentido da construção de parques, reformulações nos espaços livres, plantios de árvores nas áreas indicadas, reflorestamentos, tratamento de esgoto, reciclagem do lixo e eliminação/redução da poluição sonora, do ar, das águas e visual. / This paper goal was to analyze urban forestry in the city of Águas de São Pedro-SP, aiming to obtain important information that allows planning of a city with better environmental quality, more life quality to its inhabitants and more attractive to the tourists. Firstly, it was quantified inhabitants opinion about city urban forestry and environment. To do so, 330 people were interviewed. Most of the people cited the need of improvements in the parks, squares and city urban forestry but also pointed out environmental problems in the city. It is clear the necessity of a management plan that takes into account public opinion and technical factors. Secondly, it was analyzed the city conception and formation history and levantadas the current conditions of squares, parks, open spaces and permanent protection areas. The results were the following: a) the city has only two squares but only one is used by the population; b) about parks, one of them is private and the other three are public. From the public ones, one is highly frequented and the other two are underused. Some changes in the parks are suggested to increase the number of visitors; c) about open spaces, despite the fact the city has two dedicated areas for public events, the population complains about the few choices for entertainment in these places. The city has another five open spaces, designed in the so called garden-city urbanization project, but none of them has any landscaping treatment. Most of them is abandoned, but one is appropriate to install a park meant for children recreation, hardly wished by the population, and d) about permanent protection areas, are found in bad shape and abandoned, needing urgent actions, from reforesting to wastewater treatment. It can be stated that only a good urban project does not guarantee life and environment quality to the population, being necessary a continuous urban environment planning that includes conception, implementation, maintenance and management. Thirdly, it was used high resolution multispectra air videography, obtaining the open spaces area, trees canopy, among others. This technique was adequate to distinguish between different targets urban and to show that the city has open spaces designed in the garden-city concept that are not used. This leads to environmental, life quality and touristy potential losses. The city does not have an Environment Department, thus reinforcing the need to create one with actions towards the construction of parks, open spaces reformulation, trees planting in certain areas, reforesting, effluent treatment, waste recycling and elimination/reduction of sound, air, water and visual pollution.

Computational models of collective motion have yielded many insights about the way that groups of animals or simulated particles may move together and self-organize. Recent literature has compared predictions of models with large datasets of detailed observations of animal behavior, and found that there are important discrepancies, leading researchers to reexamine some of the most widely used assumptions. We introduce FlockOpt, an optimization-based, variable-speed, self-propelled particle model of collective motion that addresses important shortcomings of earlier models. In our model, each particle adjusts its velocity by performing a constrained optimization of a locally-defined objective function, which is computed at each time step over the kinematics of the particle and the relative position of neighboring particles. Our model explains how ordered motion can arise in the absence of an explicitly prescribed alignment term and simulations performed with our model exhibit a wide variety of patterns of motion, including several not possible with popular constant-speed models. Our model predicts that variations in speed and heading of particles are coupled due to costs associated with changes in relative position. We have found that a similar coupling effect may also be present in the flight of groups of gregarious bats. The Mexican Free-tailed bat (Tadarida brasiliensis) is a gregarious bat that forms large maternity colonies, containing hundreds of thousands to millions of individuals, in the southwestern United States in the summer. We have developed a protocol for calibrating cameras used in stereo videography and developed guidelines for data collection. Our field protocol can be deployed in a single afternoon, requiring only short video segments of light, portable calibration objects. These protocols have allowed us to reconstruct the three-dimensional flight trajectories of hundreds of thousands of bats in order to use their flight as a biological study system for our model.

Video-recorded music lessons (on multi angle DVDs) were used to inspire and improve understanding among experts from different cultures and discourses of music education. To make the process manageable and focused we developed the Analytical Short Film (2-3 minutes) to address particular areas of interest and starting points for debate. We asked selected music teachers from seven nation-states to allow a typical and (in their opinion) good lesson to be recorded. We also asked the students and their parents for permission. At a symposium, national experts and researchers presented views on „their“ lessons through Analytical Short Films. Discussion included implicit and explicit comparisons. The presenters also used a lesson from one of the other countries to stimulate discussion about assumptions in and challenges to their own views. We documented all comparisons made and compared these to derive cross cultural categories (tertia comparationis). These categories should be relevant for understanding what makes a music lesson „good“. The different perspectives and discussions offered by the authors in this book provide rich and diverse material for researchers, teachers and teacher educators.

Cette thèse porte sur ce que l'on ne voit pas dans les images et qui pourtant s'y trouve. C'est ce que signale l’expression « visiblement manquant » : le foyer émotionnel au creux duquel les signes semblent s'agencer et désigner ce qui n'est pas vu mais qui est essentiel à l'image, à l'artiste et au spectateur. L’hypothèse ici développée pose qu’il s’agirait d’un moment antérieur à l’élaboration de l'image, s'originant dans la conscience par les souvenirs, les rêves, les pensées obsessionnelles, images mentales dont le corps porte et entretient la mémoire dans ses actes moteurs comme dans l’acte même de percevoir, d’anticiper l’expérience du réel et d’éprouver la présence d’une image. S'appuyant sur ma pratique artistique de la vidéo et un ensemble d'œuvres photographiques, cinématographiques et vidéographiques puisées dans le champ des Arts visuels contemporains, la recherche chemine par des analyses précises de leurs registres iconique, plastique et sémantique. Établissant des relations entre le vu, le perçu hors-vision et le nommé, elle dessine finalement les contours d'une esthétique qui pourrait être celle de la défaillance : défaillance recherchée comme l’expression d’une fragilité, que le regard du spectateur reconnaît par sa proximité paradoxale avec sa propre vulnérabilité. / This thesis explores what is not seen and yet what can be found in images: "the visibly missing". This expression points to the center of emotions in which signs seem to be organizing themselves and designating what is unseen, and nevertheless essential to the image, to the artist and to the viewer. Our working hypothesis defines this moment as prior to the creation of the image. It originates in the conscious mind through memories, dreams, obsessional thoughts, mental images which help maintain memory alive, as well as motor behaviors like the very act of perceiving, of anticipating our experience of reality, and the act of appreciating the presence of the image itself. The research is based on my fine art video practice, as well as photographic, cinematographic and video graphic works from contemporary artistic fields, and aims to analyze precisely their iconic, artistic and semantic ranges. It also establishes links between what is seen, what is felt behind the vision, and what is named. Finally, it outlines an "aesthetics of the fainting": a deliberate fainting, expressing a fragility that the viewer's eye recognizes as such by the paradoxical proximity with its own vulnerabity.

This thesis book describes the development and production of Escape Velocity, a short narrative film. The writing, pre-production, shooting, and editing of the film are reviewed. Script drafts and a final budget are included in the appendices. The film concerns Larry Pipe and Percy Knuckle, best friends who dream of moving to Barbados. They hope to open a beachside bar and spend the rest of their days relaxing and watching girls. When Percy starts dating Melinda Bundt, however, Larry's jealousy threatens to destroy the men's friendship. When Percy needs money to follow Melinda to Atlanta, Larry must choose between supporting his best friend or pursuing their dream of Barbados alone. Escape Velocity examines the ways we hold ourselves back from pursuing our dreams, the reasons we justify doing so, and the changes in our life that finally inspire us to move toward our goals.

This is an examination of how the fictional representation and re-creation of past wars is colliding with the personal video presentations of the Iraq War. It raises questions about how war and art are experienced in a new way and also how “instant history” is made available to the public. Personally recorded footage of the everyday experience of war has altered the way in which society views war and copes with its aftereffects because Generation Y has become a computer based generation. This is a reception study that will show how Generation Y has used the Baby Boomers’ input about the Vietnam War as a basis for its perceptions of historiography and as both a positive and negative framework for its videography.
