    Transnational movements raised by globalization to a status of normality, let alone to absolute necessity, have reshaped the world and social practices (VERTOVEC, 2007; WEI & HUA, 2013). As a social practice, language dimension acquires a renewed importance in the way people use and consume languages functioning as an agent in the exercise of social and political power. Language ideologies whether individual or socioculturally constructed may be source of empowerment or, otherwise disempowerment, forging asymmetries in the way people consume languages. Thus, the pursuit of autonomy in language learning with the combination of its technical, psychological, sociocultural and political dimensions constitutes a space for (inter)personal emancipation and social transformation. Our theoretical framework emphasizes the collective aspects of learner autonomy, based on the sociocultural autonomy concept (OXFORD, 2003). Drawing on Bakhtin’s (1929/2006;1981) and Vygotsky’s (1991) contributions used as groundwork for research in learner autonomy and in consonance with ideas of fluid and hybrid identities (HALL, 1992; BAUMAN, 2005; MOITA LOPES, 2006), this paper discusses agency, empowerment and identity through sociocultural autonomy development in multicultural environments. This article is the result of two research projects conducted separately by the authors in two different contexts but related to the same research interest, which is language learning autonomy and agency in the continuous process of (re)constructing identities. Data generation was based on interviews with two speakers of Brazilian Portuguese and learners of English as an additional language, while taking part in exchange programs for international mobility – one of them in the U.S and another one in Australia. Results show that both participants seem to reframe their multiple identities, so that they adapt and readapt themselves to the new communities of practice - COPs, in which they have emerged in. Factors like agency, empowerment and sociocultural autonomy seem to be essential and decisive in this process of reframing identities.

    The aim of this paper is to examine the identity of foreign language (FL) pre-service teachers in two distinct contexts: Brazil and Chile. A multiple case study methodology was used to investigate how foreign language pre-service teachers develop and conceptualize their teacher identity in three different teacher education programs—two in Brazil and one in Chile. The analysis focused on three main issues: emerging identities, the role of foreign language proficiency, and the practicum as a mediating space to develop teacher identity. Results of the two case studies situated in Brazil suggest that FL pre-service teacher identity is shaped by their beliefs on language proficiency. The case study in Chile confirmed that pre-service teachers’ identity oscillates between identifying as students and as teachers. Overall, results of the study suggest that FL teacher identity is shaped by notions of legitimization of the teacher’s role and language proficiency.El objetivo de este artículo es examinar la identidad de los profesores de idiomas extranjeros (IE) en formación situados en dos contextos: Brasil y Chile. Con ese objetivo, se utilizó una metodología de estudio de caso múltiple para investigar la identidad de profesores de idiomas extranjeros en formación en tres contextos diferentes—dos en Brasil y uno en Chile. El análisis se centró en tres temas principals: las identidades emergentes, el papel del dominio de la lengua extranjera y la práctica pedagógica como un espacio de mediación para desarrollar la identidad docente. Los resultados de los dos primeros estudios de caso realizados en Brasil sugieren que la identidad docente de IE se ve afectada por las percepciones y creencias de profesores sobre la competencia lingüística y el nivel de proficiencia. El estudio de caso realizado en Chile confirmó que la identidad de los profesores oscila entre identificarse como estudiantes y como profesores. En general, los resultados del estudio apuntan a la conclusión de que la identidad del profesores de IE se ve afectada por las nociones de legitimación del rol y el nivel de proficiencia del IE

    he use of enzymes as catalysts requires recovery and reuse to make the process viable. Enzymatic immobilization changes enzyme stability, activity, and specificity. It is very important to explore new substrates for immobilization with appropriate composition and structure to improve the efficiency of the immobilized enzymes. This work explores the use of two different graphene oxide papers, one produced by oxidation route (GO) and the other by electrochemical synthesis (EG), aiming for β-galactosidase immobilization. The chemical and structural properties of these two papers were characterized by Raman spectroscopy, X-ray photoelectron spectroscopy and X-ray diffraction. Atomic force microscopy images showed that EG paper ensured more efficient immobilization of the enzymes on the surface of the paper. Cyclic voltammetry was used to monitor the reaction of conversion of lactose to glucose in the free enzyme solution and graphene paper immobilized enzyme solutions. The cyclic voltammetry analysis showed that immobilized enzymes on GO paper showed an improvement in the activity of β-galactose when compared to free enzyme solution, as well as enzyme immobilized on a glassy carbon electrode

    PURPOSE: To characterize the Auditory Brainstem Response (ABR) of small for gestational age preterm newborns and to compare the findings to those of appropriate for gestational age premature newborns in order to verify whether the small for gestational age condition is a risk factor for hearing loss. METHODS: This prospective cross-sectional multicenter study evaluated 72 preterm newborns of both genders (35 small and 37 appropriate for gestational age), who were born at 30 to 36 weeks of gestational age and were evaluated before hospital discharge. Only newborns with present transient evoked otoacoustic emissions and tympanometry type A were included. The ABR was performed with click stimuli. The quantitative data analysis was performed using mean and standard deviation measures for each group. For qualitative analysis, the ABR results were classified as normal or altered according to the absolute latencies of waves I, III, V and interpeaks I-III, III-V, I-V. The analysis was carried out considering the age of the newborn at the time of examination. RESULTS: Alterations were evident in 32 newborns (44.44%), being 15 small (43%) and 17 appropriate for gestational age (46%), with no between-groups difference. Of the 15 small for gestational age newborns with altered ABR, six presented as auditory risk only the small for gestational age condition. In the group of adequate for gestational age newborns, there was a higher occurrence of alteration in males. CONCLUSION: There was no difference in responses of auditory evoked potential between small and appropriate for gestational age preterm newborns. Therefore, the condition does not behave as a risk factor for retrocochlear impairment.OBJETIVO: Caracterizar as respostas do Potencial Evocado Auditivo de Tronco Encefálico em recém-nascidos pré-termo pequenos para idade gestacional, comparando-as às de recém-nascidos pré-termo adequados para idade gestacional, verificando se a condição de pequeno para a idade gestacional é indicador de risco para alteração auditiva retrococlear. MÉTODOS: Estudo multicêntrico transversal prospectivo. Avaliou-se 72 recém-nascidos pré-termo, 35 pequenos e 37 adequados para idade gestacional de ambos os gêneros, com idade gestacional de 30 a 36 semanas e avaliados na pré-alta hospitalar, com presença de emissões otoacústicas evocadas por estímulo transiente e timpanometria tipo A. A análise quantitativa dos dados foi feita baseada na média e desvio-padrão das latências das ondas I, III, V e interpicos I-III, III-V, I-V para cada grupo. Para análise qualitativa, os resultados dos potenciais evocados auditivos foram classificados em alterado ou normal mediante a análise das latências absolutas das ondas I, III, V e dos interpicos I-III, III-V, I-V, considerando-se a faixa etária no momento do exame. RESULTADOS: Evidenciaram-se alterações em 32 crianças (44,44% do total), sendo 15 recém-nascidos pequenos (43%) e 17 adequados (46%), não havendo diferença entre os grupos. Dos 15 recém-nascidos pequenos com potencial evocado auditivo alterado, seis tiveram como risco auditivo apenas o fato de ser pequeno para a idade gestacional. No grupo adequado para idade gestacional, houve maior ocorrência de alterações no gênero masculino. CONCLUSÃO: Não houve diferença nas respostas do potencial evocado auditivo entre os recém-nascidos pré-termo pequenos e adequados, de forma que a condição pequeno não se revelou risco para alteração retrococlear.Universidade de São Paulo Faculdade de Medicina Departamento de Fisioterapia, Fonoaudiologia e Terapia OcupacionalUniversidade Federal de São Paulo (UNIFESP) Departamento de FonoaudiologiaUniversidade de São Paulo Faculdade de Medicina Departamento de Pediatria, Universidade Federal de São Paulo (UNIFESP) Departamento de PediatriaUNIFESP, Depto. de Fonoaudiologia, UNIFESP, Depto. de PediatriaSciEL

    A contemporaneidade celebra a sociedade do conhecimento e da informação. O conhecimento científico e tecnológico mobiliza e alimenta sua produção, consumo e progresso. Nesse cenário, o "mercado" linguístico cresce em importância. Globalizar e internacionalizar são palavras de ordem na sociedade atual e, nela, a promoção de uma educação multilíngue assume uma preponderância estratégica. Este texto problematiza este cenário e questiona se há, no Brasil, uma política linguística que favoreça uma educação multilíngue, para que objetivos como internacionalização e incremento da produção científica e tecnológica no país tornem-se uma realidade efetiva. Os dados apresentados são parte de uma pesquisa em andamento sobre as competências linguísticas de estudantes de graduação participantes do Programa Ciência sem Fronteiras. Os dados apontam para a predominância do sistema privado de educação sobre o público e para a busca de estratégias individuais na aprendizagem de línguas estrangeiras

    Amorphous aluminum alloys have been evaluated as suitable thin films for protective coatings. Magnetron sputtering deposition may provide the necessary conditions for preparing such alloys due to its far-from-equilibrium deposition conditions. In this work, Al-Ti-C nanocomposite films were deposited by magnetron sputtering technique using TiC and Al targets. The produced films are mainly composed of Al nanocrystallites embedded into an amorphous matrix. Films effective hardness varied in the 6.4–8.2 GPa range, while their elastic modulus ranged from 109 up to 134 GPa. The higher the TiC/Al target power ratio, the harder the film. Topographic atomic force microscopy (AFM) images showed that films are mainly constituted by unevenly dispersed grains. Also, the dark phase angle fraction calculation derived from the phase angle contrast AFM images could be correlated with the deposited Al–Ti–C films hardness measured by nanoindentation tests; the higher the surface dark phase angle fraction, the harder the Al–Ti–C films.Fil: Alencastro, Felipe S..
