Estudo genealógico das viagens, dos viajantes e dos turistas

Este artigo faz um estudo genealógico da viagem e do turismo, conceitos importantes para a compreensão da sociedade ocidental, por meio da análise de certos escritos, alguns dos quais representam um marco não só na literatura, mas também na história e na antropologia. Estuda-se a construção das idéias de viagem, turismo, viajante e turista, com base na literatura e nos relatos, dos “agentes” que contribuíram tanto para a formação como para a cristalização dessas noções. Constata-se que as idéias encontradas na literatura e nos relatos acabam sendo reproduzidas nos produtos culturais da pós-modernidade, transformando ações, personagens e personalidades em construções estereotipadas.

Algoritmos culturais com abordagem memética e multipopulacional aplicados a problemas de otimização

Em muitos problemas de otimização há dificuldades em alcançar um resultado ótimo ou mesmo um resultado próximo ao valor ótimo em um tempo viável, principalmente quando se trabalha em grande escala. Por isso muitos desses problemas são abordados por heurísticas ou metaheurísticas que executam buscas por melhores soluções dentro do espaço de busca definido. Dentro da computação natural estão os Algoritmos Culturais e os Algoritmos Genéticos, que são considerados metaheurísticas evolutivas que se complementam devido ao mecanismo dual de herança cultura/genética. A proposta do presente trabalho é estudar e utilizar tais mecanismos acrescentando tanto heurísticas de busca local como multipopulações aplicados em problemas de otimização combinatória (caixeiro viajante e mochila), funções multimodais e em problemas restritos. Serão executados alguns experimentos para efetuar uma avaliação em relação ao desempenho desses mecanismos híbridos e multipopulacionais com outros mecanismos dispostos na literatura de acordo com cada problema de otimização aqui abordado.

Bem estar em cativeiro: análise e planejamento da ocupação do tempo em macacos-prego (Cebus apella)

O forrageamento é uma das principais atividades de primatas neotropicais em ambiente natural e consome grande parte do tempo diário. No ambiente de vida livre os macacos-prego podem gastar até 80% do seu tempo se deslocando e forrageando. No cativeiro, porém, não é necessário nenhum esforço dos animais para encontrar e preparar o alimento para o consumo. Portanto, a oportunidade de expressar atividades de forrageio fica praticamente excluída. O principal objetivo deste trabalho foi criar e avaliar a efetividade de uma ferramenta de enriquecimento ambiental denominada de “painel de cuia”, com a função de dificultar o acesso dos macacos-prego ao alimento, aumentando o tempo para alcançar o alimento. As observações foram realizadas em quatro contextos diferentes, sendo um na parte da manhã e três pela parte, utilizando o método de animal focal. As durações relativas de cada evento comportamental foram comparadas na ausência e presença do enriquecimento. Foi encontrado que o cuieiro estendeu o tempo de forrageamento, funcionado como instrumento de enriquecimento ambiental. Foi observado também uma considerável redução nos comportamentos anormais, ao passo que a manipulação e a procura por alimento consumiram muito mais tempo.

Desenvolvimento de aplicações Web com base em modelagem 3D: módulo portal Web

This paper presents the development of a Web application called CityFreedom based on 3D modeling. The developed system demonstrates the use of most revolutionary and innovative techniques to create Web portals with the integrated 3D navigation scenarios to their own pages, without requiring any kind of plug-ins or external software. Everything works on the basis of compatible browsers. The CtyFreedom aims to give the user the feeling of immersion in virtual reality so get to interact with a three-dimensional city in order to see new places, traveling in an area of town that has always thought of knowing or even analyze establishments long before attend-them. It's the freedom to know and traveling around the city in a simple and trivial way. It is a new trend, the future of Web systems development

Ampliação da capacidade da portaria de cargas de uma indústria através da implantação de um sistema de pesagem por eixo

Through a detailed study of each component, the structural part and various technologies for highway weighing scales, a project was developed in order to implement a modern system of axle weighing in a company pursuing to expand its cargo door capacity, which was restricted to weighing and inspection of the maximum load of each vehicle, and especially to extinguish the number of notifications that the company has been suffering, by having their transportation logistics vehicles caught traveling with poorly distributed load per axle, what it caused damage to roads and vehicles and denigrated the company image in terms of marketing. To achieve these results, the project went through a study of all relevant national legislation, seeking to put the company always in agreement. Moreover, it had investments and its physical space available for its implementation. The payback of such investments would be about less than three years

As possíveis relações entre desenvolvimento moral e uso de crack por adolescentes

The dependency of psychoactive substances whether licit or illicit, among adolescents is a topic that has aroused much discussion today. One of the psychoactive substance that has caught the attention of authorities and experts, its potential dependence, increasing the number of addicts and speed with which triggers the human degeneration is the crack (a derivative of cocaine - Erythroxylon coca), used via the smoked administration. Understanding the phenomenon of increasing their use requires an analysis of the concepts of addiction throughout history, current research encompassing scientific findings in epidemiology and statistics involving several types of pharmacological substances, and especially the analysis of data related specifically to crack the focus of our theme. In order to contribute to ongoing discussions and offer possible alternatives for effective intervention, especially in schools, we conducted a survey that sought to find evidence of a possible relationship between crack use and moral reasoning. Since our work specifically theoretical nature, we use to reach our goals, assumptions, two researchers in the concept of human morality: Jean Piaget (1994) and Lawrence Kohlberg (1992) both traveling within the proposed cognitive-evolutionary human development. For an understanding of the proposals of these two researchers, we use research to (Lepre, 2005), as guiding thesis of this work. The results presented indicate that adolescents who use crack are very close to a level of moral reasoning pre-conventional and conventional, although it is important to state that more accurate results require further research on the subject, including those involving field research. Yet we can conclude that prevention must go through a dialogue that privileges the moral education as possible means of effective intervention against the use of crack, allowing the construction of autonomy...

Inclusão escolar com apoio: uma análise do serviço do ensino itinerante

We investigated the process of inclusion in the school common areas, tracking the performance of a traveling school teacher (teaching support service specialist), type of service in Special Education, as a support to the school's educational proposal. Objectives: To identify, describe and analyze the performance of itinerant school teacher in a school of mainstream school, with students and their teachers, to analyze the perception of two teachers of the common teaching about the process of integration of pupils with special educational needs in their classes; examine the roles and responsibilities of itinerant school teacher through an exploratory qualitative approach. Participants: an itinerant school teacher, two teachers and two of the common teaching students with special educational needs included in mainstream school. Observations were made weekly at the school over a period of six months, semi-structured interviews with teachers and document analysis. The results showed different facets of roaming at the intersection with the common teaching among them may be noted that acts as a parallel system in the common school, creating a gap between them which may compromise or disadvantage of the dynamic performance of service support, but this gap is overcome at critical times facing the mainstream school, where this service benefit the child's learning process and promotes their inclusive education policy.

De um falsário a outro, de patranhas viageiras a legados críveis (século XV)

In the 15th and early 16th centuries, when traveling eastward and westward no longer proved extraordinary, travel writings, such as those of Marco Polo or Jean de Mandeville, were printed and reprinted and have been in the world of exchanges and acquisitions both in Portugal and in other parts of Europe. However, although they have played a key role in defining foreign worlds for Europe, reflecting the aspirations of their time and providing news about the universe to be discovered, these reports do not always necessarily tell of trips that were actually taken. Several of them, on the contrary, do no more than draw together, for contemporary readers, passages of interest taken from other writings; passages which, based on their regularity and frequency, would allow for a narrative staged as travel to be taken as truth for contemporaries and immediate successors. In the Iberian Peninsula of the late 15th century, an account written by an author about whom nothing is known, Gomez de Santisteban, who defines himself as a companion of Prince Pedro on a supposed trip to the Holy Land, was among those reports integrated into the description and the perception of the land being discovered. The driving question of this paper is, therefore, how Santisteban, though he wrote memories of trips that he did not take, achieved credibility like those travelers whose trips have been recognized as authentic.

An investigation into the effects of resonances on the time delay estimate for leak detection in buried plastic water distribution pipes

In water distribution systems, old metallic pipes have been replaced by plastic pipes due to their deterioration over time. Although acoustic methods are effective in finding leaks in metallic pipes, they have been found to be problematic when applied to plastic pipes due to the high damping within the pipe wall and the surrounding medium. This is responsible for the leak signal not traveling long distances. Moreover, the leak energy in plastic pipes is generally located at a narrow frequency range located at low frequencies. However, the presence of resonances can narrow even more this frequency range. In order to minimise the influence of background noise and resonances on the calculation of the time delay estimate, band-pass filters are often used to supress undesirable frequency components of the noise. The objective of this paper is to investigate the influence of resonances in the pipe system (pipe, valves, connections and hydrants), on the time delay estimate calculated using acoustic signals. Analytical models and actual leak data collected in a bespoke rig located in the United Kingdom are used to investigate this feature.
