Social representations of law, justice and injustice: A study with Argentinean and Brazilian adolescents

This study aims to analyze the main social representations of law, justice and injustice preseneted by Argentinean and Brazilian youngsters. The Brazilian group consisted of 621 polled of three different regions-Floriano/PI, Erechim/RS, and Marilia/SP. From Argentina, 200 youngsters of Avellanedacity (Buenos Aires metropolitan region) participated. All the samples were proportionally divided according to the kind of school (public or private) and the school year attented (8(th) grade and 11(th) grade, considering the equivalent grade in Argentina). The data collection technique consisted of semi directed questionnaire composed by the free evocation of words technique. The procedure used to evaluate the results was the Analysis Correspondence Method (ANACOR). The results demonstrate important variations related to the youngster' nationality and they were discussed so that the preseneted representations were contextualized.

Baixa diversidade de zooplâncton na desembocadura de uma represa eutrófica (SP, Brasil): reflexo da poluição?

The Tiete River (in São Paulo state) receives most of the efuents of the metropolitan region of São Paulo; and the Barra Bonita reservoir, 200 km distant downstream, receives and recycle most of that pollution load. This work studied the ecological features of the zooplankton (Rotifera, Cladocera and Copepoda) sampled in a point of Tiete River's mouth. Monthly samples were collected, from April, 2001 to February, 2008. The hypothesis currently tested was that the composition and availability of zooplankton were similar to the others reservoir regions (middle and lacustrine sensu Thornton) and to other reservoirs of the Upper Parana River basin, supporting the idea that these organisms manage to stand the strong pollution. The reservoir shows a typical variation of accumulation, with wide variation of seasonal altimetric grading and large fow in the rainy pe- riod, infuenced by the rainfall regime, with efects upon zooplankton assemblage. As a whole, 24 species were registered: 12 Rotifera, 8 Cladocera and 4 Copepoda. Data showed that the hypothesis formulated must be rejected, due the variation trends of zooplankton environmental attributes not being regular, with relatively high abundance values for a lotic environment in specifc months, and low organism abundance or absence in other months. Those facts can be attributed to pollution efects conducting to low dissolved oxygen concentration (> 4mg.l-1) in some months, which causes the zooplankton community to be very much afected. [K]

Air quality and emissions management in the State of São Paulo, Brazil

The São Paulo State has 36 million people, 25 million living in three metropolitan areas. Only the São Paulo Metropolitan Region (SPMR) includes the state capital (São Paulo City) plus 38 cities, where ≈ 18 million people live, affected by frequent episodes of ozone, NOx, and fine particulate matter. In 2003, it was estimated that 15.1% of the SPMR vehicles used ethanol and 70.2% used the local gasoline. Natural gas vehicles have witnessed a booming participation in the last years, mainly through conversion of gasoline cars, and the present fleet is almost one million vehicles. To face the problems generated by light vehicles emissions the Federal Government set a program called PROCONVE - Program of Air Pollution Control from Vehicles - in 1986 and since then until now a significant reduction was reached, but the growth of the fleet hides most of the emission cuts. A discussion covers the evolution of the air pollution management in São Paulo; and innovative tools for air pollution management - both for mobile and stationary sources. This is an abstract of a paper presented at the 98th AWMA Annual Conference and Exhibition (Minneapolis, MN 6/21-24/2005).

Uma caracterização do Centro de Educação Matemática - CEM (1984-1997) como uma Comunidade de prática de formação continuada de professores de matemática

This paper presents some results of a study on the Centre for Mathematics Education (Centro de Educação Matemática, CEM), a group of mathematics educators from the city of São Paulo-SP (Brazil), active mainly during the years 1984 to 1997. To establish a position on the process of identity constitution of CEM, we bring forth the method of Oral History and theories of identity. In this essay, an exercise in constituting the identity of CEM from the characterisation of this community's publications within its practice, we assume that the processes of identity constitution do not refer to what CEM is or was, but rather to a set of possibilities for apprehending it on the basis of strategies and initiatives set in given historical conditions and times. We make explicit three aspects that are present as their practice is converted into a source of coherence (mutual commitment, joint enterprise and shared repertoire), which allow one to reveal actions and production in the history of mathematics teacher education in the metropolitan region of São Paulo.

Detecção de anticorpos anti-Toxoplasma gondii em cavalos carroceiros da região metropolitana de Curitiba, Paraná, Brasil

Toxoplasma gondii, the agent for toxoplasmosis, has worldwide distribution. Horses normally play a secondary role in its life cycle, but movement around urban areas, feeding on grass and the increasing use of carthorses for gathering recyclable material in some urban areas of Brazil may increase their exposure to T. gondii infection. The aim of the present study was to investigate the frequency of anti-T. gondii antibodies in carthorses in the metropolitan region of Curitiba, PR. IgG antibodies against T. gondii were detected using the indirect fluorescence antibody test (IFAT) (titers ≥ 64). Seventeen (17.0%) of the 100 horses sampled were seropositive. There were no statistical differences in relation to sex (p = 0.28) or age (p = 0.15). Our findings suggest that carthorses are exposed to T. gondii infections and that no associations with age or sex exist.

Análise comparativa das relações entre ensino e aprendizagem por professores e alunos

In this research we identified and compared the representations of teachers and students on teaching and learning. The objective was to determine which aspects of these representations correspond to subjects and if they differ between students with high and low academic performance. Data collection was organized through a semi-structured interview. The study included twenty teachers and forty students in the 5th year of elementary school municipal public metropolitan region of Campinas. The responses from the interviews were categorized and analyzed by using the Fisher exact test, chi-square and Proportions. The results show that teachers and students present a partial view of the factors involved in teaching and learning. The learning process is understood as an individual and social factor. Teachers and students with high performance positively represent the environment of the classroom, unlike the students with lower academic performance.
