Brazil's cities in recent decades have a predominance of car use as children's mode of transport to school. In carrying out the route home-school by motorized modes children practice less physical activity to the detriment of health. Policies developed in schools can play an important role in determining how students travel to school. In this context, this research aims to identify the factors that influence the perception of managers about using the walk to access the school. The focuses of the research are the municipal and private elementary schools 1. The case study was conducted in the city of São José do Rio Preto. Data collection was carried out with the school managers (directors, coordinators and teachers) through questionnaires on travel behavior of the students, information on any activities at school to teach students to behave in traffic, opinions of management on the relationship between physical activity and health of children, children's ability to to walk to school, the barriers surrounding the school and attitude of managers regarding the use of different modes of transport and the impact of vehicle traffic in urban . The results showed that the estimation of directors and coordinators on the modes of transport used by students does not differ from a survey conducted by teachers significantly, and in private schools motorized individual transport is the most used by students and public schools over half of students walk or use public transportation to school. It was found that the traffic behavior on teaching is applied in all schools, although the directors and coordinators are more likely to say that the activities are carried out in your school. The school managers have a positive perception of the importance of physical activity, with acceptance rates above 90%. There is no consensus about the best age and abilities of children to make safe decisions alone and analysis on the perception of managers of barriers around the schools that may hinder access to foot it was found that about half of the managers have positive about the quality of the environment around the schools, but other managers have indifferent opinion about the quality of the environment. Regarding the use of different modes of transport it was observed that attitudes regarding the use of buses are in general negative, more than half of managers are indifferent to automobile use and favorable to the use of the walk. In the manager's attitude regarding the impact of vehicle traffic in urban areas the vast majority of managers are concerned about the impact of traffic on the environment. Perceptions regarding the active mobility should be worked through school policies to improve students' skills as pedestrians and through public policies to improve the environment in the school environment and encourage the use of active modes of transportation.
Provisão do Programa “Minha Casa Minha Vida” em São José do Rio Preto – SP : inserção, adequação urbana e socioeconômica de empreendimentos habitacionais

The development of a nation is directly linked to the solution of their major social problems. In Brazil, the housing deficit stands out among the social problems that need solving. However, the Brazilian government has spent the last 30 years without directing a massive investment in housing, sanitation and transport, which in turn caused serious problems in Brazilian cities. Since 2005, considering the emergence of solutions to this issue, it is observed by the federal government the resumption of investments, which gave priority to some concentrated management tools, based on the central axis of infrastructure producing that supports economic activities. At the end of the 2000s, with the worsening of an economic crisis of global reach, the federal government adopts a Keynesian and anti-cyclical strategy to resume growth: investment in public policies in housing area with the housing program called "Minha Casa, Minha Vida" (MCMV). From the urban point of view, the measures taken by the government originated sociospatial segregation and environmental problems, since the state does not equated the access to housing with city distribution, because it markedly prioritized the economic area of the PMCMV, insofar as the focus returned to the mass production of dwelling units. This work aims to understand the provision of the PMCMV in the city of São José do Rio Preto, São Paulo, Brazil, by analyzing the urban integration and socio-economic and urban appropriateness of two projects from the category 2 in the city in question. The methodology for this work was a quantitative research following the survey method (Babbie, 1999), besides using the qualitative research strategies, such as the study of post-facto case (Yin, 2010). For the application of quantitative research, 302 residents of two projects were interviewed according to a sample calculation. Then it was used a descriptive approach to treating the location of enterprises and public facilities. Based on the results of survey research, there was a correlation analysis and a factor and cluster analysis to check the interaction between the studied variables. Some researches and analysis show that PMCMV ventures in the city of São José do Rio Preto, São Paulo from the category 2 have problems of urban integration, peripheral location with limited access to transportation, health and education, as well as other issues to be addressed in this study. In conclusion, it was found a series of actions are still needed in order to perpetuate, deepen and broaden the access to housing from the point of view of public policies. Our reflections lead us to realize that the right to decent and adequate housing goes beyond distributing houses on the peripheries of cities, because it includes actions such as land-location distribution, urbanized land, a better oversight in the country of the regulation concerning the use and occupation of urban land.
Um estudo sobre crescimento de nanofios de fosfeto de índio e algumas de suas propriedades
(Universidade Federal de São Carlos, 2016-04-13) Kamimura, Hanay; Chiquito, Adenilson José; https://lattes.cnpq.br/7087360072774314; https://lattes.cnpq.br/2414357209169841
This work presents the development of an experimental apparatus and a route for the growth of InP nanowires whose general characteristics and properties made them suitable for the construction of electronic devices. Among theses characteristics, one may cite: desired dimensions, uniformity, quantity and composition. The synthesis system allowed the growth of a large amount of InP nanowires with diameter distributed around values smaller than 80 nm, grown in different substrates, covering them with a dense and uniform layer. Most important, all this in a reproducible way. The structural and morphological analyses, which resulted in the above described characteristics also allowed the observation of a amorphous/polycrystalline layer around the mono crystalline nucleus of the nanowires. Afterwards, the optoelectronic properties of the samples were studied. For this purpose, three types of devices were fabricated: single nanowire based devica, built using photolitography; nanowires network based device built from direct evaporation of contacts over the nanowires layer and from the growth of nanowires over pre defined contacts. The electronic transport mechanism was investigated by temperature dependent resistance measurements, obtaining the same dominant mechanism of hopping in all three types of device. This result indicates that the effect of the disorder attributed to the amorphous/polycrystalline layer and its interface to the monocrystalline nucleus was a critical factor to the determination of the sample’s properties. In order to complement and confirm the obtained results, other experiments were carried out: thermally stimulated current, showing additional energy levels inside the band gap, indicated in literature as levels originated from structural disorder; photo luminescence measurements, presenting a strong potential fluctuation due to localized states and photoconductivity, obtaining a sub linear dependence with the power excitation, typically observed in material with the presence of carrier traps. In this manner, the influence of localized states due to structural disorder was confirmed as the maind factor to the samples behaviour for both electronic and optical properties.
