Produção textual de adolescentes acerca da saúde sexual e reprodutiva: subsídios para atuação de enfermagem

Trata-se de um estudo exploratório-descritivo, com abordagem qualitativa, que teve por objetivo analisar as mensagens, acerca da promoção da saúde sexual e reprodutiva, produzidas por adolescentes de escolas públicas e particulares da cidade do Rio Grande, num concurso de redação e música promovido pelo Grupo Gestor Municipal (GGM) do Projeto Saúde e Prevenção nas Escolas (SPE), nos anos de 2007 e 2008. Após autorização pelo GGM para realização deste estudo, foram disponibilizadas para reprodução, via xérox, as 29 redações e as três letras de músicas inscritas nos concursos. Para o tratamento dos dados utilizou-se a técnica de análise de conteúdo na modalidade temática. Participaram 35 adolescentes, sendo 25 moças e dez rapazes, com idades entre onze e dezessete anos. Quanto à escolaridade, dois frequentavam a quinta série; doze a sexta, doze a sétima e nove a oitava. Apreendeu-se que, em sua produção textual, os(as) adolescentes revelaram as vulnerabilidades e fortalezas referentes à saúde sexual e reprodutiva. Entre os inúmeros fatores que aumentam a vulnerabilidade individual, social e programática, discorreram sobre a carência de informações, a dificuldade para transformar o conhecimento em prática, a sensação de imunidade, a violência familiar, a conduta repressora de pais e mães, as mensagens de cunho sexual veiculadas pela mídia, a necessidade de serem aceitos(as) pelo grupo, preconceitos, e falta de ações governamentais direcionadas a adolescentes. No que se refere às fortalezas, sabem que a informação é uma importante aliada para a promoção da saúde sexual e reprodutiva citando, entre as fontes acessíveis, os serviços públicos de saúde, a família e a escola. Demonstraram conhecimento acerca da alarmante propagação da epidemia da AIDS entre jovens, conhecendo os sinais e sintomas das DSTs mais comuns e as formas de prevenção. As moças enfatizaram a necessidade de compartilhar a responsabilidade preventiva com os rapazes, bem como de amor próprio e respeito mútuo. O acesso aos serviços de saúde também foi apresentado como indispensável ao adolescer saudável. Os(as) jovens demonstraram conhecimento sobre drogas seus efeitos e consequências. Referem-se à adolescência como um período gostoso, repleto de dúvidas, mas também cheio de potencialidades. Assim, os mesmos componentes apresentados como desencadeadores de vulnerabilidade podem torná-los(as) fortes e capazes de superar os desafios comuns a essa etapa da vida. Para que tal superação ocorra, é necessário que tenham acesso à informação e a problematizem; que sejam capazes de incorporá-las ao cotidiano, adotando práticas protegidas e protetoras; que haja diálogo, despido de tabus, censuras e preconceitos no ambiente familiar; que as escolas adotem de forma transversalizada temáticas referentes à saúde sexual e reprodutiva; que os serviços de saúde tenham infraestrutura para assegurar os direitos contidos no Estatuto da Criança e do Adolescente; entre outras estratégias fortalecedoras.

Ondas lusas : contributos para a análise linguística do processo de mediação na rádio pública portuguesa : abordagem pragmático-textual

A presente dissertação tem como objeto de análise as produções discursivas realizadas em dezasseis emissões do programa Em Nome do Ouvinte, emitido semanalmente na rádio pública portuguesa. As emissões escolhidas debatem o contributo da rádio pública na divulgação da língua e da cultura portuguesas. A investigação incide sobre o processo linguístico de mediação, motivado pelas mensagens dos ouvintes, os modos de receção dialógica e as estratégias de delicadeza presentes no discurso, no qual, de entre várias sequências textuais e marcadores pragmáticos, se destacam as sequências de justificação.

Pervasive Software Visualizations

A picture tells a thousand words. We all know that. Then why are our development tools showing mainly text with so much obstinacy? Even when visualizations do make it into our tools, they typically do not make it past the periphery. Something is deeply wrong. We argue that visualizations must become pervasive in software development, and to accommodate this goal, the integrated development environments must change significantly.

Experimental characterization of wingtip vortices using smoke flow visualizations

In order to predict the axial development of the wingtip vortices strength an accurate theoretical model is required. Several experimental techniques have been used to that end, e.g. PIV or hotwire anemometry, but they imply a significant cost and effort. For this reason, we have carried out experiments using the smoke-wire technique to visualize smoke streaks in six planes perpendicular to the main stream flow direction. Using this visualization technique, we obtained quantitative information regarding the vortex velocity field by means of Batchelor's model~\cite{batchelor}, which only depends on two free parameters, i.e. the vortex strength, $S$, and the virtual origin, $z_0$. Results for two chord based Reynolds numbers have been compared with those provided by del Pino et at. (2011), finding good agreement.

Towards flexible parsing of structured textual model representations

Existing parsers for textual model representation formats such as XMI and HUTN are unforgiving and fail upon even the smallest inconsistency between the structure and naming of metamodel elements and the contents of serialised models. In this paper, we demonstrate how a fuzzy parsing approach can transparently and automatically resolve a number of these inconsistencies, and how it can eventually turn XML into a human-readable and editable textual model representation format for particular classes of models.

Caminhos da crítica textual Da filologia à interdisciplinaridade: o caso das edições dos Sermões de Padre António Vieira

The present paper discusses the problem of the plurality of the text, as a cultural object, and its implications for the textual criticism activity. Starting from the fact that the nature of the textual object, especially in the case of ancient texts and literary texts, requires the editor to call into play very diverse knowledge – among which stands out the linguistic knowledge, but also the knowledge of the work, its characteristics and context – we advocate that a «philological» approach, multi and interdisciplinary, of the text editing is still needed, desirably carried out by teams of experts in different scientific fields. We exemplify, among others,with the case of the editions of the Sermões, by Vieira.

Elementos de coesão textual

Ao escrever um texto, é necessário estar atento aos elementos da coesão textual, pois são estes que criam conexão e harmonia entre as partes que o compõe para apresentar sentido e uma ideia completa. Seguir esse procedimento facilita a leitura e interpretação do leitor. Para que os parágrafos apresentem conexões, são necessários os elos entre eles, tais como os pronomes. Esta classe de palavras, portanto, são de fundamental importância na amarração das ideias colocadas em um texto. Desta forma, este recurso textual apresenta algumas formas de utilização dos pronomes como elemento de coesão textual para serem aplicadas ao se produzir uma redação

Resonancias discursivas y cortesía en prácticas de lecto-escritura

In this paper we present a study of reading comprehension based on a contrastive argumentative-discursive approach. We examine the relationship between linguistic materiality and discursive processes, observing the connection between reading in a foreign language, writing production and textual memories in the mother tongue. In addition to an interest in practical language teaching and learning processes (in this case of Spanish and Portuguese), we investigate the question of politeness and the theoretical relationship between subjectivity, language, and textuality. The latter, being understood as the result of discourse regularities, is unique for each and every production, yet is also conditioned by plural discursive memories resulting from contradictory social relationships in a specific historical context (Foucault, 1986; Pêcheux, 1990). In the experiment presented here, we follow some of the procedures of the methodology applied in the European Galatea Project developed for the study of reading strategies in the inter-comprehension between Romance languages (Dabène, 1996). We use the procedure of simulation and the subjective projection of participants as well as the notion of discursive resonance in the analysis. The results, having to do with directness and indirectness in speech and the question of politeness in two typologically close languages, lead to the conclusion that the concept of politeness goes beyond a pragmatic strategy used to avoid conflicts to be approached as a marker of cultural identity constitution. The relevance of discursive awareness and its theoretical and practical consequences are then emphasized.

Visibility of the mandibular canal on CBCT crosssectional images

The identification of the mandibular canal (MC) is an important prerequisite for surgical procedures involving the posterior mandible. Cone beam computed tomography (CBCT) represents an advance in imaging technology, but distinguishing the MC from surrounding structures may remain a delicate task. OBJECTIVES: The aim of this study was to assess the visibility of the MC in different regions on CBCT cross-sectional images. MATERIAL AND METHODS: CBCT cross-sectional images of 58 patients (116 hemi-mandibles) were analyzed, and the visibility of the MC in different regions was assessed. RESULTS: The MC was clearly visible in 53% of the hemi-mandibles. Difficult and very difficult visualizations were registered in 25% and 22% of the hemi-mandibles, respectively. The visibility of the MC on distal regions was superior when compared to regions closer to the mental foramen. No differences were found between edentulous and tooth-bearing areas. CONCLUSIONS: The MC presents an overall satisfactory visibility on CBCT cross-sectional images in most cases. However, the discrimination of the canal from its surrounds becomes less obvious towards the mental foramen region when cross-sectional images are individually analyzed.

Identificação de operantes verbais constituintes da leitura por meio da análise dos movimentos dos olhos

Os movimentos dos olhos produzem estímulos discriminativos para o comportamento de ler. O presente estudo teve por objetivo analisar os movimentos dos olhos de dois participantes durante a leitura de anagramas e identificar os operantes verbais envolvidos. A tarefa consistia em vocalizar uma palavra utilizando cinco letras. Na Fase 1, as letras formavam apenas uma palavra, sempre que observadas em uma mesma sequência espacial. Na Fase 2, formavam duas ou mais a partir de diferentes sequências. Na Fase 2, apesar da possibilidade de múltipla formação de palavras, as palavras vocalizadas foram aquelas formadas pela mesma sequência reforçada na fase anterior. Com base nos movimentos dos olhos, as vocalizações foram analisadas à luz dos conceitos de comportamento textual, auto-correção e intraverbal.

The academic plagiarism and its punishments - a review

Currently there is an increase in the occurrence of plagiarism in varied types of academic texts. Therefore, in agreement with the Brazilian Coordination of Improvement of Higher Education Personnel (CAPES) policies, Brazilian higher education institutions should establish guidelines for the detection and inhibition of academic plagiarism. However, the notion of plagiarism is extremely complex, since the ability of textual construction acquired during education is also developed using others' words. Thus, it is necessary to better know the concept of plagiarism and its implications, as well as the consequences of plagiarism and the punishments that may result from it. Consequently, rules and policies to be established will be better founded in order to address the problem of plagiarism in academic texts in a comprehensive and consistent way, not only to inhibit plagiarism but also to promote education on how is possible to create texts in an original fashion.

The Use of Latent Semantic Indexing to Mitigate OCR Effects of Related Document Images

Due to both the widespread and multipurpose use of document images and the current availability of a high number of document images repositories, robust information retrieval mechanisms and systems have been increasingly demanded. This paper presents an approach to support the automatic generation of relationships among document images by exploiting Latent Semantic Indexing (LSI) and Optical Character Recognition (OCR). We developed the LinkDI (Linking of Document Images) service, which extracts and indexes document images content, computes its latent semantics, and defines relationships among images as hyperlinks. LinkDI was experimented with document images repositories, and its performance was evaluated by comparing the quality of the relationships created among textual documents as well as among their respective document images. Considering those same document images, we ran further experiments in order to compare the performance of LinkDI when it exploits or not the LSI technique. Experimental results showed that LSI can mitigate the effects of usual OCR misrecognition, which reinforces the feasibility of LinkDI relating OCR output with high degradation.

Integration and visualization of systems biology data in context of the genome

Background: High-density tiling arrays and new sequencing technologies are generating rapidly increasing volumes of transcriptome and protein-DNA interaction data. Visualization and exploration of this data is critical to understanding the regulatory logic encoded in the genome by which the cell dynamically affects its physiology and interacts with its environment. Results: The Gaggle Genome Browser is a cross-platform desktop program for interactively visualizing high-throughput data in the context of the genome. Important features include dynamic panning and zooming, keyword search and open interoperability through the Gaggle framework. Users may bookmark locations on the genome with descriptive annotations and share these bookmarks with other users. The program handles large sets of user-generated data using an in-process database and leverages the facilities of SQL and the R environment for importing and manipulating data. A key aspect of the Gaggle Genome Browser is interoperability. By connecting to the Gaggle framework, the genome browser joins a suite of interconnected bioinformatics tools for analysis and visualization with connectivity to major public repositories of sequences, interactions and pathways. To this flexible environment for exploring and combining data, the Gaggle Genome Browser adds the ability to visualize diverse types of data in relation to its coordinates on the genome. Conclusions: Genomic coordinates function as a common key by which disparate biological data types can be related to one another. In the Gaggle Genome Browser, heterogeneous data are joined by their location on the genome to create information-rich visualizations yielding insight into genome organization, transcription and its regulation and, ultimately, a better understanding of the mechanisms that enable the cell to dynamically respond to its environment.

New perspectives on the processing and release of public information

This article discusses issues related to the organization and reception of information in the context of services and public information systems driven by technology. It stems from the assumption that in a ""technologized"" society, the distance between users and information is almost always of cognitive and socio-cultural nature, a product of our effort to design communication. In this context, we favor the approach of the information sign, seeking to answer how a documentary message turns into information, i.e. a structure recognized as socially useful. Observing the structural, cognitive and communicative aspects of the documentary message, based on Documentary Linguistics, Terminology, as well as on Textual Linguistics, the policy of knowledge management and innovation of the Government of the State of Sao Paulo is analyzed, which authorizes the use of Web 2.0, also questioning to what extent this initiative represents innovation in the environment of libraries.

Evaluation of flow patterns and elongated bubble characteristics during the flow boiling of halocarbon refrigerants in a micro-scale channel

In the present study, quasi-diabatic two-phase flow pattern visualizations and measurements of elongated bubble velocity, frequency and length were performed. The tests were run for R134a and R245fa evaporating in a stainless steel tube with diameter of 2.32 mm, mass velocities ranging from 50 to 600 kg/m(2) s and saturation temperatures of 22 degrees C, 31 degrees C and 41 degrees C. The tube was heated by applying a direct DC current to its surface. Images from a high-speed video-camera (8000 frames/s) obtained through a transparent tube just downstream the heated sections were used to identify the following flow patterns: bubbly, elongated bubbles, churn and annular flows. The visualized flow patterns were compared against the predictions provided by Barnea et al. (1983) [1], Felcar et al. (2007) [10], Revellin and Thome (2007) [3] and Ong and Thome (2009) [11]. From this comparison, it was found that the methods proposed by Felcar et al. (2007) [10] and Ong and Thome (2009) [1] predicted relatively well the present database. Additionally, elongated bubble velocities, frequencies and lengths were determined based on the analysis of high-speed videos. Results suggested that the elongated bubble velocity depends on mass velocity, vapor quality and saturation temperature. The bubble velocity increases with increasing mass velocity and vapor quality and decreases with increasing saturation temperature. Additionally, bubble velocity was correlated as linear functions of the two-phase superficial velocity. (C) 2010 Elsevier Inc. All rights reserved.
