Fisionomia e organização da vegetação do carrasco no planalto da Ibiapaba, estado do Ceará

Is the carrasco on the Ibiapaba plateau a unique plant formation? To answer this question the vertical height (except of climbers) and the stem basal diameter (from 3cm on) of woody plants were measured, and soil extracts (0-50 and 50-100cm depth) were taken from 100 random plots (10x10m) at Jaburuna (3º54'34S and 40º59'24W, altitudes near 830m), municipality of Ubajara, Ceará State. Data on climate, soil, diameter height, density, basal area, and physiognomy were compared with those surveyed by other researchers from the carrasco, caatinga, and cerrado in Northeastern Brazil. The carrasco occurs under an annual rainfall of between 668 and 1,289mm and temperatures from 22 to 24ºC, on alic Quartz Sand soils, at altitudes between 700 and 900m: it has a larger density and a smaller basal area than the caatinga and the cerrado, small and similar diameters, and an average vertical height between 3,7 and 5,4m. It differs from the caatinga, cerrado (and cerradão) and secondary forest in many items of lhe ecotope, organization and physiognomy, thus being a unique plain formation, which can be characterized as a deciduous, high, closed, and unistratified shrubland intermingled by lianas, with an irregular canopy and sparse, emergent trees.

As vozes da sociedade: letramento, consciência e poder

The dialectic tension between the phenomenon of illiteracy and the remedial efforts of the literate to provide a voice for those who don t have one, reflects at the same time the difficulties that the emerging discourses have to struggle with, and highlights the importance of this struggle as one that belongs to the opressed, not the well-meaning educators and political activists. It also informs the latter s efforts on behalf of the uneducated. Naturally these issues have attracted a good deal of attention of some specialists in South America. There is now a movement afoot there that aims at placing illiterate discourse inside the societal discourse proper without letting the latter manipulate the former for its own ends. I will address the typical exigencies and limitations inherent in such efforts, but at the same time point to new ways of understanding and handling the problem of literacy in a developing country.

Sociedade, cultura, matemática e seu ensino

One of the effects of the globalized world is a strong tendency to eliminate differences, promoting a planetary culture. Education systems are particularly affected, undergoing strong pressure from international studies and evaluations, inevitably comparative, and sadly competitive. As a result, one observes the gradual elimination of cultural components in the definition of education systems. The constitution of new social imaginaries becomes clear; imaginaries empty of historical, geographical and temporal referents, characterized by a strong presence of the culture of the image. The criteria of classification establish an inappropriate reference that has as its consequence the definition of practices and even of education systems. On the other hand, resistance mechanisms, often unconscious, are activated seeking to safeguard and recover the identifying features of a culture, such as its traditions, cuisine, languages, artistic manifestations in general, and, in doing so, to contribute to cultural diversity, an essential factor to encourage creativity. In this article, the sociocultural basis of mathematics and of its teaching are examined, and also the consequences of globalization and its effects on multicultural education. The concept of culture is discussed, as well as issues related to culture dynamics, resulting in the proposition of a theory of transdisciplinar and transcultural knowledge. Upon such basis the Ethnomathematics Program is presented. A critique is also made of the curriculum presently used, which is in its conception and detailing, obsolete, uninteresting and of little use. A different concept of curriculum is proposed, based on the communicative (literacy), analytical (matheracy), and material (technoracy) instruments.

A língua inglesa no ensino fundamentl I público: diálogos com Bakhtin por uma formação plurilíngue

This article aims at discussing the contributions of the Bakhtinian Circle theories to foreign language teaching and learning (HALL et al., 2005), as far as the first years of formal education in Brazil are concerned. Up to the present moment, foreign languages, including English, are not officially part of the National Curriculum of the first five schooling years. Due to the importance of English in a globalized world and despite all the controversial socio-educational impacts of such an influence, there has been an increase in the interest in this discipline at the beginning years of Brazilian public education (ROCHA, 2006), which has been happening at an irregular pace and without official parameters. Therefore, the relevance of this work lies on the possible guidelines it may offer to support a more effective, situated and meaningful teaching-learning process in that context. Standing for a pluralistic approach to language education, we take the bakhtinian speech genres as organizers of the educational process. We strongly believe that through a dialogic, pluralistic and trans/intercultural teaching (MAHER, 2007), whose main objective is the development of multi (COPE e KALANTZIS, 2000) and critical (COMBER, 2006) literacies, the hybridization of genres and cultures, as well as the creation of third spaces (KOSTOGRIZ, 2005; KUMARAVADIVELU, 2008) can happen. From this perspective, foreign language teaching and learning play a transformative role in society and English is seen as a boundary object (STAR e GRIESEMER, 1989), in and by which diversity, pluralism and polyphony can naturally find their way.

Consenso brasileiro para a abordagem clínica e tratamento do hipotireoidismo subclínico em adultos: recomendações do Departamento de Tireoide da Sociedade Brasileira de Endocrinologia e Metabologia

INTRODUCTION: Subclinical hypothyroidism (SCH), defined as elevated concentrations of thyroid stimulating hormone (TSH) despite normal levels of thyroid hormones, is highly prevalent in Brazil, especially among women and the elderly. Although an increasing number of studies have related SCH to an increased risk of coronary artery disease and mortality, there have been no randomized clinical trials verifying the benefit of levothyroxine treatment in reducing these risks, and the treatment remains controversial. OBJECTIVE: This consensus, sponsored by the Thyroid Department of the Brazilian Society of Endocrinology and Metabolism and developed by Brazilian experts with extensive clinical experience with thyroid diseases, presents these recommendations based on evidence for the clinical management of SCH patients in Brazil. MATERIALS AND METHODS: After structuring the clinical questions, the search for evidence in the literature was initially performed in the MedLine-PubMed database and later in the Embase and SciELO - Lilacs databases. The strength of evidence was evaluated according to the Oxford classification system and established based on the experimental design used, considering the best available evidence for each question and the Brazilian experience. RESULTS: The topics covered included SCH definition and diagnosis, natural history, clinical significance, treatment and pregnancy, and the consensus issued 29 recommendations for the clinical management of adult patients with SCH. CONCLUSION: Treatment with levothyroxine was recommended for all patients with persistent SCH with serum TSH values > 10 mU/L and for certain patient subgroups.

Ituglanis mambai, a new subterranean catfish from a karst area of Central Brazil, rio Tocantins basin (Siluriformes: Trichomycteridae)

Ituglanis mambai, new species, is described from a cave in the Mambaí karst area, State of Goiás, Central Brazil. The new species distinguishes from epigean and cave congeners by the combination of the following characteristics: posterior supraoccipital fontanel absent; pectoral-fin rays usually i,7; six pleural ribs; total vertebrae 37-38 behind Weberian apparatus; shorter predorsal length (65.1-70.8% SL); shorter caudal peduncle length (8.4-11.9% SL); shorter dorsal-fin base length (7.7-11.3% SL); wider interobital width (29.2-36.5% HL); larger mouth width (43.4-64.0% HL); intermediate between epigean and other cave Ituglanis species as regards to both eyes (diameter varying from 0.5 to1.0 mm in adults, 7.8-10.1 % HL) and pigmentation, composed by irregular light brown spots along the body. The latter indicate the troglobitic status for I. mambai. In addition, this species has the maxillae with a discrete medial-posterior projection; fronto-lacrimal one half-length of the maxillae and pointed backwards; posterior process of palatine half its length, with a tenuous medial concavity; 14 dorsal and 12 ventral procurrent rays. In the natural habitat, I. mambai displayed cryptobiotic habits, trying to hide in the graveled bottom or under boulders when disturbed, apparently showing a negative response to light. It was observed a preference to slow-moving waters. Recent flood marks were observed in the stream conduit in March/April 2007 (end of the rainy season) when less individuals were observed on 300 m of the subterranean stream compared to September 2004 (end of the dry season).

Potamotrygon boesemani (Chondrichthyes: Myliobatiformes: Potamotrygonidae), a new species of Neotropical freshwater stingray from Surinam

Potamotrygon boesemani, new species, is described from the Corantijn river drainage in Surinam. The species has a diagnostic dorsal color pattern formed by deep orange to red ocellated spots of irregular form, encircled by relatively broad black rings. Potamotrygon boesemani is distinguished from other ocellated congeners (P. motoro, P. henlei and P. leopoldi) by the more intensely colored ocelli, which are usually yellow in the latter species. From P. motoro it is also distinguished by the darker dorsal background coloration, by the broader black contour of the dorsal ocelli, and by the irregular form of the ocelli as compared to the more rounded shape in the latter species. From P. henlei and P. leopoldi, it is distinguished by the lack of ocelli on tail. From the tentatively identified specimen of P. ocellata, which also has dark orange ocelli, the irregular contour of the ocelli in the new species is also distinctive. The teeth are relatively smaller and in greater number than in P. motoro and P. ocellata, with up to 45 rows in the upper jaw.

“Memória e sociedade”: ciência poética e referência de humanismo

O artigo apresenta um conjunto articulado de reflexões a respeito do livro Memória e Sociedade: Lembranças de Velhos, de Ecléa Bosi, aqui considerado como obra-prima da psicologia social e das ciências humanas. Procura destacar as originalidades de natureza teórico-metodológica do texto, a começar por uma composição singular que incorpora poesia na construção científica, passando por uma redefinição das relações entre sujeito e objeto do conhecimento, ao desenvolver a perspectiva de alternância da condição entre ambos, no desdobramento da pesquisa. Mostra, também, como o estudo de Ecléa Bosi se fundamenta em estreitos vínculos entre a pesquisadora e os velhos pesquisados, de modo a se formar entre eles uma comunidade de destino.
