Escolas públicas?: o difícil acesso ao ensino de qualidade no Brasil
Jennifer Perroni,André Brando
Vértices , 2010,
Abstract: A desigualdade educacional atinge níveis alarmantes no Brasil. No ensino superior, é notório que institui es públicas apresentam difícil acesso para a parcela economicamente mais vulnerável da popula o. O presente trabalho pretende demonstrar, através de uma pesquisa empírica, que essa desigualdade também ocorre no acesso a institui es públicas de ensino fundamental e médio que se destacam pela excelência ou pela tradi o. Nossa investiga o se volta para o concurso realizado pelo Colégio Pedro II no início do ano de 2007 e tem, como pano de fundo, o Censo Educacional 2006 e os resultados do vestibular da UFF para o ano de 2005. Public Schools?: the difficult access to quality education in Brazil Educational inequality reaches alarming levels in Brazil. In higher education, it is widely known that it is difficult for the most economically vulnerable portion of the population to be admitted in public educational institutions. This paper aims at demonstrating, through empirical research, that this inequality is also found in admission processes carried out by prominent public institutions of primary and secondary education. Our investigation focuses on admission examinations held by Colégio Pedro II in early 2007, and is also based on data from the Educational Census 2006 and results of the UFF entrance examination for the 2005 school year.

Abstract: this article presents and discusses data obtained with the application of a questionnaire focused on variables for racial classification and opinion about the policy of quotas for blacks; the questionnaire was applied to a sample of 476 pupils from the last year of secondary education of the public school system of a peripheral town in the metropolitan area of rio de janeiro. we have tried to understand the elements that shape the classifications of color or race, as well as the stance these pupils were taking before a policy of quotas that could help them in their attempts to have access to a public university. it must be noted that the pupils interviewed would soon be facing the possibility of competing for a place in higher education via an entry exam with racial quotas to a public university that keeps a campus in the same town where they live and study. this problem and this kind of investigation seem to us fundamental nowadays, because quotas for blacks have been put in place since 2003 at several institutions of higher education, and have been subjected to criticism and undergone juridical dispute, as a result, among other things, of the forms of classification proposed. in the study conducted here it was possible to advance in the discussion of how the options of racial classification used so far in these policies are related with the forms of self-identification and identification of the other commonly present in the daily lives of the schools researched, and also to observe how the idea of a racial quota is evaluated by its potential beneficiaries.

Abstract: Cassava flours are obtained from the roots of Manihot esculenta Crantz and daily fairly consumed by the Brazilian population considering it comes to hum food, and also inserted into food baskets, besides to present low cost and easy access, in addition to being plant easily cultivated by the population. However, the food obtained with cassava may contain hydrocyanic acid, in the form of cyanogenic glycoside when those meals are not cooked properly. The oral toxicity can range 30 - 210 mg/kg body, the average daily consumption per capita in larger rural areas than in urban areas for cassava flour 19.1 g against 4.7 g, respectively. Brazil’s North and Northeast have higher consumption of cassava flour, associated with family monthly monetary income, making this region more vulnerable to poisoning. The objective of this study was to quantify cyanogenic glycosides present in some types of Brazilian cassava foods by means of spectrophotometric technique (reading at a wavelength of 530 nm). For quantitative determination of cyanide content, linamarase hydrolysis was used. The amount of cyanide was determined, and results were: artisan toasted cassava flour: 15 mg/500g, sweet cassava starch: 32.5 mg/500g, artisan dried cassava flour: 37.5 mg/500g, “bijuzada” cassava flour: 60 mg/500g, industrialized, toasted cassava flour: 115 mg/500g, industrialized, raw cassava flour: 140 mg/500g, and wet cassava flour: 225 mg/500g. Considering the chronic ingestion of cyanide present in these foods, they can cause public health problems.
Barcoding lepidoptera: current situation and perspectives on the usefulness of a contentious technique
Silva-Brando, Karina L;Lyra, Mariana L;Freitas, André V L;

Abstract: faced by a growing need of identification and delimitation of new and established cryptic species that are being lost at an increasing rate, taxonomists can now more than ever take advantage of an enormous variety of new molecular and computational tools. at this moment they should be open to all new available technologies in the so called "technology-driven revolution" in systematics. the use of the "dna barcode" has been discussed by those applying successfully this approach to identify and diagnose species and by those who believe that the flaws in the use of this molecular marker are as many as to negate the worth of its employment. for insects of the order lepidoptera neither side seems totally correct orwrong, and although many groups of lepidopterans have been taxonomically resolved by using exclusively or additionally this marker for diagnoses, for others the "barcode" helped little to resolve taxonomic issues. here we briefly present some pros and cons of using dna barcode as a tool in taxonomic studies, with special attention to studies with groups of lepidoptera developed in the last few years.
Plant-plant associations and population structure of four woody plant species in a patchy coastal vegetation of Southeastern Brazil
Correia, Cristiane Maria Brando;Dias, André Tavares Corrêa;Scarano, Fabio Rubio;
Brazilian Journal of Botany , 2010, DOI: 10.1590/S0100-84042010000400009
Abstract: we examined plant population structure and interspecific associations for juveniles and adults of four woody species (andira legalis (vell.) toledo, clusia hilariana schltdl., protium icicariba (dc.) marchand and vernonia crotonoides sch. bip. ex baker) in a patchy vegetation on a sandy coastal plain (restinga) in se - brazil. we found 101 vegetation patches in a 0.5 ha grid and these were divided into two distinct size classes, with large patches (> 20 m2) containing the majority of adult individuals of the species studied. the most abundant species, p. icicariba (465 individuals) and c. hilariana (312), had actively regenerating populations, whereas a. legalis (20) and v. crotonoides (338) showed evidence of intermittent regeneration. the regeneration niches of the four species differed as did their investment in vegetative reproduction: for instance, 81% of c. hilariana seedlings were found growing inside tank-bromeliads contrasting with only 3% of p. icicariba in this habitat. additionally, 28% of regenerants of c. hilariana originated vegetatively, contrasting with only 6% for p. icicariba. all significant associations between species found in the study were positive. there was a positive association between adults of c. hilariana and p. icicariba, as well as between adults of c. hilariana and juveniles of both. this suggests that p. icicariba is successfully establishing under the canopy of c. hilariana and highlights the role of c. hilariana in generating vegetation cover that will be later dominated by other woody plant species, as an important process for maintenance of plant diversity in this restinga vegetation.
