This monograph aims to contribute to the understanding and analysis of extreme events and its correlation with anthropogenic actions, in order to understand the levels of human interference in the environment and to identify potential social and environmental damage that such events may result in Ubatuba, located on the northern coast of São Paulo state. Therefore, two strategies were established, on one hand, episodic analysis of extreme weather events, and on the other, the analysis of the impact of atmospheric phenomena in everyday society. In this case we gave greater emphasis to analysis years that had higher total rainfall. In this sense, the research was based on the standard deviation technique and percentages, which supported to characterize the exceptional rainy years, in addition, use of rhythm analysis technique that has helped to identify the active atmospheric systems. From a qualitative point of view, field works were carried out in order to make use of news by the local press and civil defense for years considered extreme (positive standard deviation). From this, it was analyzed how the extreme episodes of rainfall trigger repercussions in geographic space. Also the spatial distribution of rainfall were carried out by means of quantitative analysis of six rain gauges. It was found that the highest occurrences of impacts, are located in the central areas of the city, as well as the highest rainfall totals. In fact, Ubatuba/SP suffers from very high rainfall totals and has a singularity on the climate...

The main objective of this paper is to answer the following question: how can we draw a parallel, during the analysis of the data, between children who are at different moments in the language acquisition process or who belong to different populations (children that are monolingual, bilingual, with language disorders, etc.)? In order to answer this question, we are discussing the advantages and limitations of adopting a measure like MLU, from English Mean Length of Utterance, or EME as it was named in Brazil, proposed by Roger Brown (1973). We intend to verify the effective contribution of these measures to the studies in the area and propose an adaptation in the studies that use a qualitative approach. Firstly, we recall the study of the criteria proposed by Brown (1973), Scliar-Cabral (1976), Parker & Brorson (2005), Parisse & Le Normand (2006), and Araújo (2007), and by scholars of Brazilian Portuguese morphology, like Câmara Jr (2009), Monteiro (2002), and Kehdi (1990), among others. Secondly, from a dialogic-discursive point of view (BAKHTIN, 2006; BAKHTIN/ VOLOSHINOV, 1992, 1981), we provide as an example the research on the plural in the language acquisition process (HILÁRIO, 2010, 2011b, 2012). The reflections made indicate that EME may be a useful measure for the researches on language acquisition. Nevertheless, adaptations should be done and its inherent problems should be taken into account, especially if other factors are considered – like the age, the number of types/occurrences, the maximum limit of items per utterance etc. – although it is not the only parameter of analysis. Considering that EME may vary according to the conditions of production and may not reflect the qualitative changes in the children’s discourse, other factors should be analyzed, like the context of the discourse, the participants involved etc.

Human activities have been driven land cover, provoking acceleration of the erosive process and alteration on the soil characteristics. To explore the effects of human disturbance, we investigated the influences of natural and anthropogenic features on soil quality and soil erosion indicators (EI) within a Brazilian rural watershed located in Bauru Municipality, State of So Paulo. A pre-established set of soil EI was used to evaluate the influence of anthropogenic land cover categories on the presence and severity of erosion, related with spatial variations of soil attributes. On-site visits were carried out to measure the occurrence and the intensity of eleven separate EI values and to collect undisturbed topsoil samples for subsequent analyses. We registered 17 occurrences of EIs, distributed in ten locals. Occurrence and intensity of EIs were related to degree of sheet erosion. The EI qualities were more strongly associated with land cover management practices than to local topographic features. The occurrence of EIs and characteristics of soil and soil organic matter (SOM) were not significantly self-correlated. Although land cover class seems to influence soil properties and SOM attributes, we observed that the granulometric composition of the soils also contributes to the structural characteristics of the soil and consequently to the dynamic loss and gain of soil carbon. Sites covered with natural remnant vegetation (NRV) store 96.5 Mg ha(-1) of C and grassy and tilled soils stored more C than NRV, 100.1 and 142.4 Mg ha(-1), respectively. Due to the influence of soil texture over the soil C dynamic, we observe that in Bauru, pastured areas have high potential for sequestration of C if factors such as fire and/or erosion were avoided or effectively controlled. Results from this study show that human disturbance substantially affects soil properties within of southeastern region of Brazil.
