Profile of micronucleus frequencies and nuclear abnormalities in different species of electric fishes (Gymnotiformes) from the Eastern Amazon

The frequency of spontaneous micronucleus (MN) formation in fish species needs to be determined to evaluate their usefulness for genotoxic biomonitoring. The definition of a good bioindicator takes into account the current knowledge of its metabolic traits as well as other factors including its feeding behavior and relationship to the environment. In this study, we compared the basal frequencies of micronucleated erythrocytes and nuclear abnormalities (NA) among different species of the fish Order Gymnotiformes (Rhamphichthys marmoratus, Steatogenys elegans, Sternopygus macrurus, Parapteronotus hasemani, Gymnotus mamiraua, Gymnotus arapaima, Brachyhypopomus beebei, Brachyhypopomus n. sp. BENN) sampled in several localities of the Eastern Amazon. A baseline of MN and NA frequency in these fish was determined, enabling the identification of potentially useful species as models for genotoxicity studies. Only one impacted sample collected at a site in the River Caripetuba showed a significant number of NAs, which may be due to the release of wastewater by neighbouring mining industries and by the burnt fuel released by the small boats used by a local community. Our results may provide support for further studies in areas of the Eastern Amazon affected by mining, deforestation and other anthropogenic activities.

Multilatinas na global economy. historical characterization, sectorial and space

The successive crises for which has passed in the world economy since the years 1970, together with the United States 'hegemonic crisis, have created the conditions for the reordering and the construction of a multipolar world, with the increasing importance of some peripheral countries into the world economy, particularly with regard to capital flows. This article represents an effort to bring to light the analysis on the decrease of importance of developed countries in world investment flows and corresponding increase in the relevance of some peripheral countries. The objective underlying the text is understanding the expansion of space circuits of production of multinational companies in Latin America (Multilatinas) at different spatial scales, by means of an analysis of the temporal, spatial and sectoral dimensions of the investments. The methodological procedures adopted covered survey, selection and bibliographic data compilation, reading in international organizations (UNCTAD and ECLAC), systematization of data, analysis of data in the light of the theoretical reflections.

Concepções de 'palavra' em escolas de educação infantil

We searched for which conceptions twenty-three Kinden garden teachers would have of “word”, as well as for “echoes” from these conceptions in their 4-6 years old pupils. Essentially all the teachers showed a graphic and semantic conception of “word”. “Echoes” from these conception were detected in part of their pupils. The other part of children showed a conception in which could be detected enunciative, pragmatic and discursive aspects of language. Conception of teachers indicates ruptures between their pedagogic activities with literacy and their pedagogic activities with language unities such as word. These ruptures, however, not necessarily were made by part of children, who seems integrate language and literacy.

A insegurança e as novas práticas espaciais em cidades brasileiras

New real estate launch products and closed residential spaces, occurs with increasing frequency in Brazilian cities and are based on the assumption that there is a general increase in violence, as we address urban insecurity, which involves individual coping, and privatizing adept practices of exacerbated control mechanisms. We researched deployment and appropriation of residential spaces in middle cities of Sao Paulo (Brazil). We identify social representations of the others, blamed for insecurity growing, and analyzed from everyday life perspective. We hypothesized that new forms of production of urban space with a tendency to social and spatial fragmentation, generate new practices.

A relação fala-escrita em dados produzidos em contexto digital

This paper aims to explain certain language phenomena remarkable for example in the Internet. These phenomena are popularly known as “internetês” in Brazilian Portuguese writing texts. A set of texts collected from chats was analyzed based on discoursive and phonological studies. The relationship between spoke and writing is seen as a distinctive character of heterogeneity of writing. In a particular way, the writing of nicknames in these digital interactions is analyzed. It is shown that enunciative complexity came from different linguistic information (phonological, morphological, semantics and enunciative ones). This study aims to contribute for general questions about oral/spoken and literacy/writing in digital context (but not just in those contexts).

Reflexõs sobre a linguagem do ambiente chat no Teletandem sob a perspectiva da natureza heterogênea da escrita

This paper aims at discussing the characteristics of computer mediated language within a foreign language teaching and learning environment enabled by the use of synchronic writing resources – chat. The present research is based on (i) theoretical principles about the use of technologies and the teaching-learning of foreign languages in the scope of the Teletandem Brazil Project: Foreign languages for all – Projeto Teletandem Brasil: línguas estrangeiras para todos (TELLES, 2005); (ii) studies on the characteristics of the language within chat interactions; (iii) different theoretical perspectives on the relationship between spoken and written language, emphasizing the constitutive heterogeneity of writing perspective (CORRÊA, 1997, 1998, 2001); and (iv) some relevant concepts related to Prosodic Phonology field (NESPOR; VOGEL, 1986). Is being taken as research data, the written production of a Brazilian student (finishing a Licentiate in Literature) interacting with an American student (in Religious Studies) through Windows Live Messenger. The data were collected during a five-month period, during which the participants interacted through chat, totalizing 12 interactions in English and in Portuguese. During the analysis, a particular attention was given to the messages’ fragmentation, the use (or not) of punctuation signs and abbreviations within the Brazilian participant’s production, in order to discuss the representations she built of her writing, her interlocutor, herself and on the teaching-learning process of a foreign language.

Letramentos acadêmicos e multimodalidade em contexto de EaD semipresencial

From a theorethical enunciative-discursive perspective, this article aims at discussing the process of the text consistency in digital context, in a particular manner, by means of problematic semiotic modes and resources updated in the academic production of the student who uses internet access computers in the semi-present Distant Learning (DL) process. It’s of interest to investigate how the academic literacies model may be linked to the multimodality study, considering, in theory, that in an electronic environment, the student has “unlimited” access to every and any kind of text, not just the “verbal” (name generally attributed to the graphic component) one. The collected material contains texts which were produced by the semi-present Pedagogy Course students from the Virtual University of São Paulo (UNIVESP), in 2010.

A abordagem histórica do letramento: Ecos da memória na atualidade

The word literacy acquired a polysemy spectrum which put it away from the notion of social and historic process, at the same time that associates it to codification and decodification of writing. Concerning to this last perspective, we would have nothing to add. However, we sustain, in this paper, considering Pêcheux´s Discourse Analysis and Lacanian Psychoanalysis approaches, that there is a conception of literacy as a phenomenon which influences indirectly individuals and cultures for whom the competence of writing is not established. In this sense, the concept of literacy is larger than alphabetization. As an evidence of this proposal, we analyze a text written by a student, that demanded him to write about a context distant from his own, and, to do so, he mobilized places from the archive and from his particular memory, showing a singular knowledge of writing culture, even though his text presents interpenetration of oral an writing forms, aspect that is not allowed by those who defend an a-historical conception of literacy. We discuss that the student’s text ran away from the reduction of a merely pedagogic ideology and reflects a discursive coherence in face of the challenge that was proposed to him. By the end of this paper, we propose that the teachers should search for devices that make easier for their students to write texts in which their authorship could emerge.
