Comparative analysis of two techniques for detection and segmentation of moving bodies

This paper makes a comparative analysis of results produced by the application of two techniques for the detection and segmentation of bodies in motion captured in images sequence, namely: 1) technique based on the temporal average of the values of each pixel recorded in N consecutive image frames and, 2) technique based on historical values associated with pixels recorded in different frames of an image sequence.

Chuva, vulnerabilidade social e percepção do risco na cidade de São Paulo: impactos de eventos extremos nos bairros da Freguesia do Ó e do M’Boi Mirim

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.

Biogeography of the social wasp genus (Hymenoptera: Vespidade: Polistinae)

Aim The aim of this study was to understand the biogeography of Brachygastra. As the spatial component of evolution is of fundamental importance to understanding the processes shaping the evolution of taxa, the known geological history of the Neotropical region was used together with the current phylogeny and distribution of species to investigate questions concerning the biogeography of Brachygastra: the ancestral ranges of Brachygastra species; their areal relationships and their congruence with previously published hypotheses; the possible associated vicariance events and the influence of land bridges between North and South America, and the split between the Amazon and Atlantic forests. Location Neotropical region, from Mexico to central Argentina and southern USA. Methods Statistical dispersal–vicariance analysis (S-DIVA) was used to reconstruct the possible ancestral ranges of Brachygastra species based on their phylogeny (divided into three groups, lecheguana, scuttelaris and smithii). A Brooks parsimony analysis (BPA) and component analysis were performed to reconstruct the areal relationships of these species within the Neotropics. Results S-DIVA suggested a widespread, South American ancestral region for Brachygastra. The ancestral B. azteca probably reached the Nearctic before a posterior vicariance event separated it from the species groups ((lecheguana (scutellaris + smithii))), that stayed in the Atlantic forest. The ancestral (scutellaris + smithii groups) possibly reached the Amazon by dispersal, and the subsequent vicariance event splitting the Atlantic forest and Amazon separated the groups into scutellaris in the Atlantic forest and smithii in the Amazon. BPA and component analyses suggested that the Nearctic was a sister area to other regions, the Andes and Mesoamerica was a sister area to the Neotropical regions and the Amazon was closely related to the Atlantic forest. Main conclusions The phylogeny and distribution of Brachygastra suggest the influence of a land bridge between the Northern and Southern Hemispheres affecting the cladogenesis of B. azteca and the importance of the formation of the two blocks of forests in South America to the cladogenesis of the main groups of Brachygastra. Future comparisons between the distribution patterns of other taxa should enable a more precise identification of the possible events and outcomes, adding robustness to the hypothesized areal relationships.

Meios de comunicação social de massa e a agressividade do espectador de futebol

The mass media have a decisive function in formation of opinion and conduct of population. Among those, the television is a vehicle with great power of spread of information. The objective this study is to analyze the influence of media on occurrences regarding the aggressiveness some participants involved in event soccer, while spectators. The subject's attitude is determined by predominant factors, among them the influences of social and cultural way in that lives, as well as, of the education and sporting influences that it affects. The problem of violence in the sport, in the case of soccer, it cannot be addressed for total responsibility of media. However, collaboration is indispensable, for aspect positive and/or negative, depending on the interest in subject. The models of behavior in television could influence the spectator's behavior for a learning process, for example, the use of the language. Therefore, it is indispensable to rethink the roads of television, their ethical conducts and to discuss the philosophical sense of the crisis. Because, to reject the mass media is to deny the reality and social transformations. The extent of the Physical education, above all in the school, is a fundamental space for the teacher to intermediate the meaning of the sport, in this case, the soccer-spectacle, in social context and their relationships with the media, enlarging the process civilization, so much inside as out of field.
