Este artigo empreende a análise do discurso dos capítulos cinco e sete do documento do Banco Mundial: Para além do consenso de Washington: a importância das instituições, identificando e questionando a proposição de modelos teóricos para as reformas da administração pública e educacional na América Latina, com fundamento em autores preocupados em examinar o conceito de modelo teórico. A intenção é discutir as categorias envolvidas, suas ambigüidades e seu caráter inovador/conservador e definir se as propostas contidas no texto referido são nacional e regionalmente adequadas, se detêm o poder de transformar a realidade ou constituem apenas algo mais sobre a mesma coisa ou, pior, traduzem o resgate/elogio de modelos remodelados, inspirados na teoria empresarial, que alimentam a crítica dos acadêmicos regionais há décadas.

Este trabalho investiga o aspecto qualitativo da Reforma Psiquiátrica no interior do estado de São Paulo, por meio da análise dos discursos presentes no campo da Saúde Mental. Balizamo-nos no referencial da Atenção Psicossocial enquanto corpo teórico-prático e ético para transformação paradigmática em Saúde Mental. Como método, utilizamos entrevistas semi-dirigidas com coordenadores de CAPS e coordenadores municipais de Saúde Mental, e observações participantes, analisadas por meio do método dialético de análise de discurso. Foram encontradas três matrizes teóricas principais dos discursos (Psiquiatria Tradicional, Psiquiatria Preventivo-Comunitária, Atenção Psicossocial) coexistindo no espaço institucional. A vertente Preventivo-Comunitária mostrou-se bem instalada e superando técnica e teoricamente a Psiquiatria Tradicional, porém dificultando o avanço da Atenção Psicossocial em termos éticos.

O câncer é uma doença que traz indagações para a pessoa que passa por essa experiência e transtornos dos mais variados, podendo gerar estresse que é inevitável e faz parte da vida humana. Para manejar o estresse há diferentes formas de adaptação a uma situação. O sucesso desse manejo vai depender das estratégias de coping (enfrentamento), definido como um processo utilizado para controlar as demandas da relação indivíduo-ambiente que serão elaboradas pelo indivíduo. Este trabalho teve como objetivo identificar as formas de enfrentamento utilizadas diante dessa doença e do tratamento. Realizou-se estudo qualitativo, através da Análise de Discurso do Sujeito Coletivo e referencial teórico de coping. Foram entrevistados 16 pacientes em tratamento radioterápico, sendo a amostra constituída por conveniência. Pode-se observar que os participantes, ao enfrentarem o câncer e a radioterapia elaboraram estratégias de enfrentamento tanto baseadas na emoção, como no problema.

Este estudo tem como objetivo analisar as concepções de licenciandos em Química e em Física sobre a prática profissional e as marcas deixadas pelas disciplinas pedagógicas na sua formação, assim como identificar sinais de mudanças em suas concepções durante a realização do curso de Licenciatura. Para tanto, textos foram produzidos por 54 alunos matriculados em cursos de Licenciatura de duas universidades públicas do estado de São Paulo, nos quais os licenciandos expressaram suas experiências de formação e apontaram elementos que consideram que terão alguma influência em sua atuação profissional. Os textos revelaram que as ideias que os licenciandos carregam são consistentes com muitas das visões e objetivos apresentados em cursos de formação de professores. Nas produções dos estudantes faz-se presente o desejo de compartilhar e promover em seus futuros alunos o interesse pela Química e a Física. Os seus comentários refletiram visões de professores que tiveram no passado, os quais gostariam de imitar, e de outros que não gostariam de ser. Os comentários também tornaram evidente a vontade dos licenciandos em se estabelecerem como professores que se preocupam com seus alunos. Os textos foram analisados segundo a Análise do Discurso de linha francesa, como tem sido divulgada por Eni Orlandi, especialmente a noção de formação discursiva.

The objective of the present article is to identify and discuss the possibilities of using qualitative data analysis software in the framework of procedures proposed by SDI (socio-discursive interactionism), emphasizing free distribuited software or free versions of commercial software. A literature review of software for qualitative data analysis in the area of social sciences and humanities, focusing on language studies is presented. Some tools, such as: Wef-tQDA, MLCT, Yoshikoder and Tropes are examined with their respective features and functions. The software called Tropes is examined in more detail because of its particular relation with language and semantic analysis, as well as its embeded classification of linguistic elements such as, types of verbs, adjectives, modalizations, etc. Although trying to completely automate an SDI based analysis is not feasible, the programs appear to be powerful helpers in analyzing specific questions. Still, it seems important to be familiar with software options and use different applications in order to obtain a more diversified vision of the data. It is up to the researcher to be critical of the analysis provided by the machine.

This paper describes two solutions for systematic measurement of surface elevation that can be used for both profile and surface reconstructions for quantitative fractography case studies. The first one is developed under Khoros graphical interface environment. It consists of an adaption of the almost classical area matching algorithm, that is based on cross-correlation operations, to the well-known method of parallax measurements from stereo pairs. A normalization function was created to avoid false cross-correlation peaks, driving to the true window best matching solution at each region analyzed on both stereo projections. Some limitations to the use of scanning electron microscopy and the types of surface patterns are also discussed. The second algorithm is based on a spatial correlation function. This solution is implemented under the NIH Image macro programming, combining a good representation for low contrast regions and many improvements on overall user interface and performance. Its advantages and limitations are also presented.

Building on the foundations of French Discourse Analysis and Social Psychology's developments on the issue of stereotypes, this paper analyzes the images of women available in works of self-help for women. With this purpose in mind, we have especially taken into account aphorizing enunciations present in works of this kind currently circulating in the market. The analysis shows the contradiction inherent to the self-help discourse for women, which proposes to women a pattern of behavior consistent with their emancipation, but, at the same time, contributes to keeping certain female stereotypes associated with their traditional roles.

Glasses in the ternary system (70 - x)NaPO3-30WO 3-xBi2O3, with x = 0-30 mol %, were prepared by the conventional melt-quenching technique. X-ray diffraction (XRD) measurements were performed to confirm the noncrystalline nature of the samples. The influence of the Bi2O3 on the thermal, structural, and optical properties was investigated. Differential scanning calorimetry analysis showed that the glass transition temperature, Tg, increases from 405 to 440 C for 0 ≤ x ≤ 15 mol % and decreases to 417 C for x = 30 mol %. The thermal stability against devitrification decreases from 156 to 67 C with the increase of the Bi2O3 content. The structural modifications were studied by Raman scattering, showing a bismuth insertion into the phosphate chains by Bi-O-P linkage. Furthermore, up to 15 mol % of Bi 2O3 formation of BiO6 clusters is observed, associated with Bi-O-Bi linkage, resulting in a progressive break of the linear phosphate chains that leads to orthophosphate Q0 units. The linear refractive index, n0, was measured using the prism-coupler technique at 532, 633, and 1550 nm, whereas the nonlinear (NL) refractive index, n 2 was measured at 1064 nm using the Z-scan technique. Values of 1.58 ≤ n0 ≤ 1.88, n2 ≥ 10-15 cm 2/W and NL absorption coefficient, α2 ≤ 0.01 cm/GW, were determined. The linear and NL refractive indices increase with the increase of the Bi2O3 concentration. The large values of n0 and n2, as well as the very small α2, indicate that these materials have large potential for all-optical switching applications in the near-infrared. © 2012 American Chemical Society.

Autism is a neurodevelopmental disorder characterized by impaired social interaction and communication accompanied with repetitive behavioral patterns and unusual stereotyped interests. Autism is considered a highly heterogeneous disorder with diverse putative causes and associated factors giving rise to variable ranges of symptomatology. Incidence seems to be increasing with time, while the underlying pathophysiological mechanisms remain virtually uncharacterized (or unknown). By systematic review of the literature and a systems biology approach, our aims were to examine the multifactorial nature of autism with its broad range of severity, to ascertain the predominant biological processes, cellular components, and molecular functions integral to the disorder, and finally, to elucidate the most central contributions (genetic and/or environmental) in silico. With this goal, we developed an integrative network model for gene-environment interactions (GENVI model) where calcium (Ca2+) was shown to be its most relevant node. Moreover, considering the present data from our systems biology approach together with the results from the differential gene expression analysis of cerebellar samples from autistic patients, we believe that RAC1, in particular, and the RHO family of GTPases, in general, could play a critical role in the neuropathological events associated with autism. © 2013 Springer Science+Business Media New York.

Honey bee venom toxins trigger immunological, physiological, and neurological responses within victims. The high occurrence of bee attacks involving potentially fatal toxic and allergic reactions in humans and the prospect of developing novel pharmaceuticals make honey bee venom an attractive target for proteomic studies. Using label-free quantification, we compared the proteome and phosphoproteome of the venom of Africanized honeybees with that of two European subspecies, namely Apis mellifera ligustica and A. m. carnica. From the total of 51 proteins, 42 were common to all three subspecies. Remarkably, the toxins melittin and icarapin were phosphorylated. In all venoms, icarapin was phosphorylated at the 205Ser residue, which is located in close proximity to its known antigenic site. Melittin, the major toxin of honeybee venoms, was phosphorylated in all venoms at the 10Thr and 18Ser residues. 18Ser phosphorylated melittin-the major of its two phosphorylated forms-was less toxic compared to the native peptide. © 2013 WILEY-VCH Verlag GmbH & Co.
