Indicadores de floresta urbana a partir de imagens aéreas multiespectrais de alta resolução

The present work evaluated urban forest indicators, acquired through airborne high-resolution multiespectral images, on the quality of the urban design and its vegetative fraction, in special its trees, in nine neighborhoods of Piracicaba, SP. There were made supervised classifications for characterization of intra-urban elements and the proportions obtained, as exposed soil, tree cover, lawns, asphalt, concrete pavements and roofs. They were studied for the measurement of the urban forest in each place. These variables were related to each other, as well as with the independent variables: population density, people with more than fifteen years of study and family heads with income above twenty minimum wages, obtained through population census. Through the analysis of linear regression variables were identified for intra-urban areas evaluation. Correlations were made and linear regressions among the data obtained from the image and among the proposed indicators. Negative correlations were obtained among population density and arboreal covering and the evaluated indices, in accordance with the predicted in the literature. Composite indicators are proposed, as: the proportion between arboreous space on waterproof space (PAW) and the proportion between arboreous space on building space (PAB). It is concluded by the possibility of the use of those indicators for evaluation of the urban forest and definition of priorities in the execution of ordinances to the improvement of the urban forestry, being prioritized the application of resources in the most lacking neighborhoods.

Avaliação de fatores de risco de cães sororreagentes à leptospira spp. e sua distribuição espacial, em área territorial urbana

We aimed to evaluate the risk factor of serum reactive dogs to antileptospire agglutinin and their spatial distribution in an urban area. We collected 1,000 blood samples from dogs at 20 immunization centers, homogeneously distributed in the urban area (32 km²) of Botucatu, Sao Paulo, Brazil. Diagnosis was made by microscopic serum agglutination using 24 serovars of Leptospira spp. Statistical analysis was performed by Goodman's test with 5% of significance. Spatial clusters were tested by spatial scan statistic using SaTScan. We found that 17.9% dogs reacted to Leptospira spp. (p<0.0001). Dogs with street access (22.14%) were more reactive (p<0.05) than those without (14.83%). The scan test indicated only one significant cluster influenced by age. Incorporating each one of the co-variables gender, breed, and street access to age, we found that street access was the most important. Street access and age were the most important risk factors in the large number of reactive animals in the cluster, with the castellonis serovar being the most reactive in urban dogs. The identification of a cluster with more reactive dogs than expected allows local preventive measures to be taken.

Investigação soroepidemiológica de leptospirose canina na área territorial urbana de Botucatu, São Paulo, Brasil

Leptospirosis was seroepidemiologically investigated in 775 dogs from Botucatu, state of Sao Paulo, in blood samples collected during the annual anti-rabies vaccination campaign. The samples were collected from 14 out of the 45 vaccination stations geographically distributed in five different municipal districts, with a territorial urban area of 31Km2. Samples were taken from 449 males and 326 females; 564 were of undetermined breed, and 211 were pedigree animals; ages ranged from 3 months to 20 years. Diagnosis included the microscopic serum agglutination tests using 12 Leptospira spp serovars. Serological results and epidemiological variables were compared using Goodman and chi-square tests, with χ=0.05. There were 119 (15.3%) positive samples for 11 serovars; the most important was canicola with 48 (40.3%), followed by pyrogenes 41 (34.5%). Statistical analysis showed significant difference for: breed, 17.7% positive in undetermined breeds and 9.0% in pedigrees; and sex, 18.4% positive in males and 11.0% in females. There was no statistically significant difference in relation to age with uniform distribution of positives.

A relação entre modernização neoliberal e práticas políticas atrasadas no Brasil dos anos 1990

Our goal is to investigate the reasons behind the presence of clientelist-type practices among the popular classes in Brazil, highlighting the decade of the 1990s. Our proposal gives salience to factors regarding the phenomenon's socio-political conjuncture, thereby taking us beyond explanations that rely exclusively on historical-cultural aspects or that sustain an economic bias. We use bibliographic and journalistic sources, from which we develop our own interpretation of the period. Thus, we observe that clientelist practices are encouraged to manifest themselves at the level of national political organization particularly within the federal sphere yet are also reflected at state and municipal levels, due to the coalition of political forces created through the implantation of a neoliberal project in Brazil. The latter has joined modern Brazilian social democracy and old regional oligarchies situated primarily within the PFL, PP, PTB and certain sectors of the PMDB, whose representatives are known for their attachment to patrimonialist and paternalistic practices. The inclusion of the latter in the conservative pact that has promoted neo-liberal political reform has thus meant awarding new value to such practices. Herein lies partial explanation for the vigor with which practices such as fisiologismo, apadrinhamento, abuse of state machinery, buying and selling of votes and clientelism have manifested themselves on the national scene over the course of the 1990s.

Hidrogeoquímica do aqüífero guarani na área urbana de ribeirão preto (SP)

This work evaluated the hydrogeochemistry of the Guarani Aquifer in the urban area of Ribeirão Preto, São Paulo State. Thirty one sampling points were established and it was carried out field campaigns in 7 and 8 July 2005, analyzing the following parameters: conductivity, temperature, pH, turbidity, color, dry residue, dissolved oxygen, Ca2+, Mg2+, Na+, K+, Fe3+, Al3+, HCO3-, SO42-, PO43-, NO3-, Cl- and F-. The results indicated that the groundwaters in the urban area of Ribeirão Preto pH possess slightly acid, low conductivity, turbidity, color and dissolved oxygen inside the limits established for drinking waters. The ionic composition indicated that the groundwaters have low cations and anions concentration, being they classified as soft water and calcium-bicarbonated. Statistical tests suggested that conductivity and pH are controlled for the calcite dissolution (CaCO3) during the water/rock interaction process. Besides, it is possible to conclude that the high NO3- and PO43- concentrations found in the groundwater in the urban area of Ribeirão Preto are originated due to anthropogenic activities.

Mujer urbana y el servicio doméstico: Colombia

El proyecto en torno a las condiciones socio-laborales del servicio domestico en Colombia es amplio y procura la transformacion ideologica de lo que se entiende por servicio domestico. El primer material educativo consiste en un boletin basico de las normas laborales como paso inicial de seminarios y charlas sobre la legislacion complementada con asesoria legal a las propias afectadas. Estas acciones se han realizado en Bogota y se estan iniciando en Cali y durante un ano se han atendido a 3.500 personas en liquidacion de sus funciones y a 1.500 en asistencia juridica y legal (p164). La segunda etapa del proyecto consiste en trabajar no solo con la empleada sino tambien con la patrona y se encuentra en sus inicios. En terminos globales, el proyecto ha difundido material de utilidad que esta actualmente en manos de abogados y juristas, habiendose realizado seminarios con diversas instancias del Ministerio del Trabajo.
