New real estate launch products and closed residential spaces, occurs with increasing frequency in Brazilian cities and are based on the assumption that there is a general increase in violence, as we address urban insecurity, which involves individual coping, and privatizing adept practices of exacerbated control mechanisms. We researched deployment and appropriation of residential spaces in middle cities of Sao Paulo (Brazil). We identify social representations of the others, blamed for insecurity growing, and analyzed from everyday life perspective. We hypothesized that new forms of production of urban space with a tendency to social and spatial fragmentation, generate new practices.

The emergence of the digital order renewed the Victorian civilizing ideal and strengthened a world order of techno-economic dependence. The new grand narrative is the urgency of digital transformation of societies; a dream pursued without reflection by the populations of the periphery that ended into in a collision between McLuhan's two informational orders: cold and hot societies. Latin America as part of the periphery did not participate in the development of the informatic technologies and its historical legacy made the appropriation of these technologies more difficult. This paper examines the historical circumstances of this process: the development of a discourse around the digital networks, the consequences of this social construction in the region, the fragile efforts of Brazil to create technology, and the entrance of IT networks in the region. The results showed that the status of this kind of research in the region is weak so we alert about its consequences. We concluded that to create an informational order that may serve as a space of self-affirmation, freedom and heterogeneity, it is necessary to have a deep knowledge of the social and historical context that created its basic technologies, but Latin America is indifferent in such regard. Information Science has a central role in the region within this process but it has not developed it yet.

During the process of development and urban sprawl in the city of Presidente Prudente (SP), some factors as the emergence of new centralities, the change in lifestyles and the expansion of equipments and urban infrastructure contributed to the dismantling and little appropriation of the central open space system. In this sense, the work is about the loss of continuity between the central squares of the city - Monsenhor Sarrion Square, July 9 Square, Bandeira Square and Nossa Senhora Aparecida Square - using different methodologies for character evaluation of each square, identifying the inviting and unattractive aspects of their spaces. The relations between these squares and its surroundings are characterized by analyzing interesting visual played on sketches, to complement character evaluation. Among these studies, it is also analyzed two spatial structures related to the squares – Calçadão and Quintino Bocaiuva Street - which have important architectural referring to the city's history and contribute to the central open space system configuration. General considerations obtained through diagnosis provided subsidies for the projectual proposed intervention, which aims to provide appreciation of the character of these public spaces and their articulation, promoting their use and constituting, thus, an important urban-environment set

The city of São Paulo has, since the beginning of the expansion of its urban sprawl, represented relations of conflicts and contradictions between society and nature. Once the way society relates to nature is defined by how the social agents themselves correlate in certain social and historical contexts, the ways of interaction between the social and natural elements will be different according to the forms of production and appropriation of the urban space. Even more evident is the case of the great national metropolis, given its demographic dimensions and historical conditions, the process of urban expansion follows a logic where spaces of better quality for housing are occupied by those of better financial conditions. Thus, although there are exceptions, the poorest people live in places less desirable, in less resilient environments of lower environmental quality, relating to nature and its phenomena with greater risks. These risks are reflected here as recurring flooding, mudslides and landslides for which the rain is constantly blamed. So we have a situation where it is clear that a weather phenomenon differently interacts with different social groups. In this context, the study was conducted to compare extreme events occurred in two regions of São Paulo: the Freguesia do O, in the north side, and M'Boi Mirim, in the south side. Both are regions with large number of risk areas and are in the same urban climate unit. However, they present different conditions of social vulnerability. With the investigation of each extreme rain event occurred in the two regions, in the period of 2000-2010, supplemented by field research, we tried to observe how far the rain, with his intensity and volume, can, in fact, be related to the accidents.

The increasing number of space debris in operating regions around the earth constitutes a real threat to space missions. The goal of the research is to establish appropriate scientific-technological conditions to prevent the destruction and/or impracticability of spacecraft in imminent collision in these regions. A definitive solution to this problem has not yet been reached with the degree of precision that the dynamics of spatial objects (vehicle and debris) requires mainly due to the fact that collisions occur in chains and fragmentation of these objects in the space environment. This fact threatens the space missions on time and with no prospects for a solution in the near future. We present an optimization process in finding the initial conditions (CIC) to collisions, considering the symmetry of the distributions of maximum relative positions between spatial objects with respect to the spherical angles. For this, we used the equations of the dynamics on the Clohessy-Witshire, representing a limit of validation that is highly computationally costly. We simulate different maximum relative positions values of the corresponding initial conditions given in terms of spherical angles. Our results showed that there are symmetries that significantly reduce operating costs, such that the search of the CIC is advantageously carried out up to 4 times the initial processing routine. Knowledge of CIC allows the propulsion system operating vehicle implement evasive maneuvers before impending collisions with space debris.

The aim of the present study was to determine the effects of motor practice on visual judgments of apertures for wheelchair locomotion and the visual control of wheelchair locomotion in wheelchair users who had no prior experience. Sixteen young adults, divided into motor practice and control groups, visually judged varying apertures as passable or impassable under walking, pre-practice, and post-practice conditions. The motor practice group underwent additional motor practice in 10 blocks of five trials each, moving the wheelchair through different apertures. The relative perceptual boundary was determined based on judgment data and kinematic variables that were calculated from videos of the motor practice trials. The participants overestimated the space needed under the walking condition and underestimated it under the wheelchair conditions, independent of group. The accuracy of judgments improved from the pre-practice to post-practice condition in both groups. During motor practice, the participants adaptively modulated wheelchair locomotion, adjusting it to the apertures available. The present findings from a priori visual judgments of space and the continuous judgments that are necessary for wheelchair approach and passage through apertures appear to support the dissociation between processes of perception and action.

This work aims to analyze the limitations of recent Brazilian urban expansion and, more specifically, the housing policy for low-income population, focused on Minha Casa, Minha Vida in Campinas / SP . It is understood that this program aims to democratize access to housing for excluded populations in the property market, resulting in a right to the city. This policy is analyzed in the living space configuration from the point of view of socio-spatial segregation. To meet the flexibility of real estate developers, urban politic Campinas was subsumed by the entrepreneurship of housing production, was detached from the municipal planning and releasing ownership of urban land for the free flow of capital that circulated by the real estate market in the search for the appropriation of elevation of the ground rent . These processes are understood through intense confinement of poverty in areas that grow randomly deleted and the margin of urban rights
