The design, implementation and production process of creating a viable series of Latin shows in Hollywood, Florida

The purpose of this research was to design and implement a Series of Latin Shows to be featured at the Satine Restaurant located in The Diplomat Hotel in Hollywood, Florida. Three shows were created: "Electro Tango," "Bossa Nova Jazz," and "Piel Canela Night" to help generate interest for not only the Satine Restaurant but also for the surrounding area. The artistic concept included big bands, costumes, dancers and a DJ. A production book was created and included the most important aspects of the individual shows such as budgets, costumes, and ground plans, to assure the success of each event. Careful analysis was done for the demographic area and a marketing plan was designed and implemented. The research and practical application of similar shows in the industry determined that the production of these particular shows, although costly, have a qualifiable chance to succeed in this venue.

Measuring the sustainability of a national economy. The application of three measures of sustainability to Ireland

An assessment of the sustainability of the Irish economy has been carried out using three methodologies, enabling comparison and evaluation of the advantages and disadvantages of each, and potential synergies among them. The three measures chosen were economy-wide Material Flow Analysis (MFA), environmentally extended input-output (EE-IO) analysis and the Ecological Footprint (EF). The research aims to assess the sustainability of the Irish economy using these methods and to draw conclusions on their effectiveness in policy making both individually and in combination. A theoretical description discusses the methods and their respective advantages and disadvantages and sets out a rationale for their combined application. The application of the methods in combination has provided insights into measuring the sustainability of a national economy and generated new knowledge on the collective application of these methods. The limitations of the research are acknowledged and opportunities to address these and build on and extend the research are identified. Building on previous research, it is concluded that a complete picture of sustainability cannot be provided by a single method and/or indicator.

Development of sexing systems functional to mass production of Aedes albopictus sterile males

Aedes albopictus is a vector able to transmit several arboviruses. Due to its high impact on human health, it is important to develop an efficient control strategy for this pest. Nowadays, control based on chemical insecticides is limited by the number of available active principles and the occurrence of resistance. A valuable alternative to the conventional control strategies is the sterile insect technique (SIT) which relies on releasing sterile males of the target insect. Mating between wild females and sterile males results in no viable offspring. A crucial aspect of SIT is the production of a large number of sterile males with a low presence of females that can bite and transmit viruses. The present thesis aimed to find, implement and study the most reliable mechanical sex sorter and protocol to implement male productivity and reduce female contamination. In addition, I evaluated different variables and sorting protocols to enable female recovery for breeding purposes. Furthermore, I studied the creation of a hyper-protandric strain potentially able to produce only males. I also assessed the integration of artificial intelligence with an optical unit to identify sexes at the adult stage. All these applications helped to realise a mass production model in Italy with a potential weekly production of 1 million males. Moreover, I studied and applied for aerial sterile male release in an urban environment. This technology could allow the release of males in a wide area, overcoming environmental and urban obstacles. However, the development and application of drone technologies in a metropolitan area close to airports, such as in Bologna area, must fit specific requirements. Lastly, at Réunion Island, during a Short Term Scientific Mission France (AIM-COST Action), Indian Ocean, I studied the Boosted SIT application. Coating sterile males with Pyriproxyfen may help spread the insecticide into the larval breeding sites.

Tecnologia assistiva e computacional : contribuições para o atendimento educacional especializado e desafios na formação de professores

Neste trabalho, analisamos aspectos relacionados a como a tecnologia computacional é utilizada no Atendimento Educacional Especializado (AEE) e como se deu a formação de professores para utilizar esses recursos. Para tanto, delimitamos os seguintes objetivos específicos: investigar a utilização da tecnologia assistiva (TA) computacional no âmbito das salas de recursos multifuncionais (SRM); problematizar as tensões, dificuldades e possibilidades relacionadas à TA com ênfase na tecnologia computacional para o AEE; analisar a formação do professor de educação especial para o AEE tendo como recurso a TA com ênfase na tecnologia computacional, visando à mediação dos processos de aprendizagem. O aporte teórico deste trabalho foi a abordagem histórico-cultural, tomando por referência os estudos de Vigotski e seus colaboradores. Trata-se de uma pesquisa qualitativa que fez uso de diferentes instrumentos metodológicos como, os grupos focais, o questionário online e a entrevista semiestruturada. Para desenvolvê-lo, realizamos a coleta de dados em diferentes contextos, começando pelos grupos focais da pesquisa inaugural do Oneesp, que serviram como dispositivo para esta pesquisa, seguida da aplicação de um questionário aos professores participantes da pesquisa-formação desenvolvida como um desdobramento no estado do Espírito Santo da pesquisa inaugural do Oneesp pelos integrantes do Oeeesp e da aplicação in loco de entrevistas semiestruturadas com professores de educação especial, de uma SRM do Tipo II. Foram oitenta e nove professores participantes na pesquisa do Oneesp, trinta professores na pesquisa-formação do Oeeesp e dois professores para aplicação da entrevista semiestruturada in loco, respectivamente. Esses dois professores participaram tanto da pesquisa do Oneesp como da pesquisa do Oeeesp. Analisamos esses três momentos, dos quais emergiram os apontamentos que nos proporcionaram pensar, com base nas narrativas orais e escritas dos professores: sua formação para uso da TA computacional; seu entendimento sobre sua formação para este fim; seus anseios por uma formação mais direcionada; a forma como utilizam a tecnologia na sala de recursos; seus entendimentos sobre as dificuldades e possibilidades relacionadas a TA com ênfase na tecnologia computacional para o AEE. Após essas análises, concluímos que poucos professores que atuam nas SRM tiveram uma formação que possibilitasse a aplicação das tecnologias computacionais em sua mediação pedagógica, aliando teoria e prática, com momentos de formação que privilegiassem os momentos presenciais e em laboratórios, onde possam interagir com os computadores e suas ferramentas simbólicas. Sem essa familiaridade com os recursos computacionais, os professores acabam sentindo-se inseguros para utilizá-los, deixando de potencializar, pela via desses recursos, os processos de ensinoaprendizagem do aluno com deficiência. Faz-se necessário um investimento nesse tipo de formação e, mais do que isso, que se viabilize para os professores que atuam ou que pretendem atuar nas SRM. A partir de uma formação apropriada é possível fazer com que os professores utilizem os recursos computacionais como mediadores dos processos de ensino-aprendizagem de seus alunos.

Application of two-dimensional wavelet transform in near-shore X-band radar images

Among existing remote sensing applications, land-based X-band radar is an effective technique to monitor the wave fields, and spatial wave information could be obtained from the radar images. Two-dimensional Fourier Transform (2-D FT) is the common algorithm to derive the spectra of radar images. However, the wave field in the nearshore area is highly non-homogeneous due to wave refraction, shoaling, and other coastal mechanisms. When applied in nearshore radar images, 2-D FT would lead to ambiguity of wave characteristics in wave number domain. In this article, we introduce two-dimensional Wavelet Transform (2-D WT) to capture the non-homogeneity of wave fields from nearshore radar images. The results show that wave number spectra by 2-D WT at six parallel space locations in the given image clearly present the shoaling of nearshore waves. Wave number of the peak wave energy is increasing along the inshore direction, and dominant direction of the spectra changes from South South West (SSW) to West South West (WSW). To verify the results of 2-D WT, wave shoaling in radar images is calculated based on dispersion relation. The theoretical calculation results agree with the results of 2-D WT on the whole. The encouraging performance of 2-D WT indicates its strong capability of revealing the non-homogeneity of wave fields in nearshore X-band radar images.

Application of GPR in the study of a modern alluvial megafan: The case of the Taquari river in Pantanal wetland, West-Central Brazil

A novel and timely ground penetrating radar (GPR) survey has been carried out in Pantanal from Mato Grosso State, west-central Brazil. Fieldwork was carried out on February/2001 and August/2002 in an attempt to understand avulsion processes that are occurring within Taquari alluvial megafan. The main objectives were to map channel, crevasse and floodplain morphology, as well as active sedimentary bedforms. Many GPR profiles were acquired in the medium and lower Taquari River course. Subaqueous megaripples and exposed sand bars were identified in the medium fan area. Similar features were observed in the lower fan channels, where there were many crevasses in the marginal levees. During the flooding seasons, the flow splays out on to the floodplain, where new distributary channels are being formed. GPR data show that the lower fan, Taquari channel is topographically higher than the adjacent floodplain, thus favoring avulsion as a natural process of river course shifting. GPR data obtained during the wet and dry seasons, together with sedimentology information have been very important in characterizing the fluvial dynamics, and avulsion phenomena. © 2005 Springer Science+Business Media, Inc.
