"Knock, knock! Is it english or portuguese sign language?"

A presente investigação mostra a importância do contacto de crianças muito jovens com línguas estrangeiras. Este trabalho concentra-se na tentativa de investigar, numa abordagem plurilingue, com enfoque para a Língua Inglesa e a Língua Gestual Portuguesa, a sensibilização de um grupo de alunos do 1º Ciclo do Ensino Básico para uma língua diferente da sua língua materna. Nesta pesquisa, adotou-se uma postura de investigação-ação, apoiando-se com grande particularidade numa metodologia qualitativa e com menor relevância numa metodologia quantitativa, onde os alunos, através das várias atividades que desenvolveram foram adquirindo diferentes competências nas duas línguas. Isto permitiu aos alunos despertarem todas as suas potencialidades para a aprendizagem destas duas línguas (Língua Inglesa e Língua Gestual Portuguesa), tendo como ponto de partida a sua sensibilização e a aprendizagem de alguns vocábulos. Acreditamos que esta abordagem plurilíngue poderá auxiliar os alunos no desenvolvimento de habilidades linguísticas, cognitivas e pessoais tais como: a intercompreensão, o conhecimento de características específicas de diferentes línguas existentes em seu redor, a comparação linguística entre elas, a sua compreensão lexical, e por fim a competência em relacionar as línguas a culturas, e acima de tudo, o respeito e valorização da diversidade linguística e cultural. Foram utilizadas nas aulas atividades de nível de compreensão e produção oral, num processo de sensibilização e aprendizagem de alguns vocábulos destas línguas, sendo que os resultados foram posteriormente analisados, através de grelhas de observação das atividades, de dois inquéritos por questionário e fotos. Das observações e conclusões retiradas desta análise, confirmou-se que a sensibilização quanto à Língua Inglesa assim como quanto à Língua Gestual Portuguesa promove o desenvolvimento da criança, assim como a valorização da respetiva diversidade linguística e cultural.

The rebirth of an old language: issues of gender equality in Kazakhsstan

The existing language situation in Kazakhstan, while peaceful, is not without some tension. We propose to analyze here some questions we consider relevant in the frame of cultural globalization and gender equality, such as: free from Russian imperialism, could Kazakhstan become an easy prey of Turkey’s “imperialist dream”? Could these traditionally Muslim people be soon facing the end of religious tolerance and gender equality, becoming this new old language an easy instrument for the infiltration in the country of fundamentalism (it has already crossed the boarders of Uzbekistan), leading to a gradual deterioration of its rich multicultural relations? The present structure of the language is still very fragile: there are three main dialects and many academics defend the re-introduction of the Latin alphabet, thus enlarging the possibility of cultural “contamination” by making the transmission of fundamentalist ideas still easier through neighbour countries like Azerbaijan, Uzbekistan and Turkmenistan (their languages belong to the same sub-group of Common Turkic), where the Latin alphabet is already in use, and where the ground for such ideas shown itself very fruitful.

Differences in Mismatch Negativity (MMN) response to Pure-tone and Speech sounds in normal subjects: an additional explanation

The relation of automatic auditory discrimination, measured with MMN, with the type of stimuli has not been well established in the literature, despite its importance as an electrophysiological measure of central sound representation. In this study, MMN response was elicited by pure-tone and speech binaurally passive auditory oddball paradigm in a group of 8 normal young adult subjects at the same intensity level (75 dB SPL). The frequency difference in pure-tone oddball was 100 Hz (standard = 1 000 Hz; deviant = 1 100 Hz; same duration = 100 ms), in speech oddball (standard /ba/; deviant /pa/; same duration = 175 ms) the Portuguese phonemes are both plosive bi-labial in order to maintain a narrow frequency band. Differences were found across electrode location between speech and pure-tone stimuli. Larger MMN amplitude, duration and higher latency to speech were verified compared to pure-tone in Cz and Fz as well as significance differences in latency and amplitude between mastoids. Results suggest that speech may be processed differently than non-speech; also it may occur in a later stage due to overlapping processes since more neural resources are required to speech processing.

Língua adicional: contextos e continua

O papel de uma língua adicional, seja ela uma língua estrangeira, língua segunda, ou uma variedade não nativa, é fundamental atualmente não só no domínio profissional mas também em termos de investigação científica, mais precisamente sobre o contacto de línguas. Até ao início da segunda metade do século passado, o contacto linguístico que poderá ter estado na origem das línguas crioulas gozou de especial atenção entre os linguistas. Nas últimas décadas a sua atenção virou-se para a língua segunda e as variedades não nativas. Neste artigo, apresentamos,do ponto de vista teórico, os elos de ligação, contextos e continua, entre os quatro conceitos acima referidos, em que o primeiro, língua adicional, é apresentado como hiperónimo dos outros três, língua estrangeira, língua segunda e variedade não nativa.

Digital storytelling: an integrated approach to language for the 21st century student

Societal changes have, throughout history, pushed the long-established boundaries of education across all grade levels. Technology and media merge with education in a continuous complex social process with human consequences and effects. We, teachers, can aspire to understand and interpret this volatile context that is being redesigned at the same time society itself is being reshaped as a result of the technological evolution. The language- learning classroom is not impenetrable to these transformations. Rather, it can perhaps be seen as a playground where teachers and students gather to combine the past and the present in an integrated approach. We draw on the results from a previous study and argue that Digital Storytelling as a Process is capable of aggregating and fostering positive student development in general, as well as enhancing interpersonal relationships and self-knowledge while improving digital literacy. Additionally, we establish a link between the four basic language-learning skills and the Digital Storytelling process and demonstrate how these converge into what can be labeled as an integrated language learning approach.

Eastwards / westwards: which direction for gender studies in the 21st century?

Eastwards / Westwards: Which Direction for Gender Studies in the XXIst Century? is a collection of essays which focus on themes and methods that characterize current research into gender in Asian countries in general. In this collection, ideas derived from Gender Studies elsewhere in the world have been subjected to scrutiny for their utility in helping to describe and understand regional phenomena. But the concepts of Local and Global – with their discoursive productions – have not functioned as a binary opposition: localism and globalism are mutually constitutive and researchers have interrogated those spaces of interaction between the ‘self’ and the ‘other’, bearing in mind their own embeddedness in social and cultural structures and their own historical memory. Contributors to this collection provided a critical transnational perspective on some of the complex effects of the dynamics of cultural globalization, by exploring the relation between gender and development, language, historiography, education and culture. We have also given attention to the ideological and rhetorical processes through which gender identity is constructed, by comparing textual grids and patterns of expectation. Likewise, we have discussed the role of ethnography, anthropology, historiography, sociology, fiction, popular culture and colonial and post-colonial sources in (re)inventing old/new male/female identities, their conversion into concepts and circulation through time and space. This multicultural and trans-disciplinary selection of essays is totally written in English, fully edited and revised, therefore, it has a good potential for an immediate international circulation. This project may trace new paths and issues for discussion on what concerns the life, practices and narratives by and about women in Asia, as well as elsewhere in the present day global experience. Academic readership: Researchers, scholars, educators, graduate and post-graduate students, doctoral students and general non-fiction readers, with a special interest in Gender Studies, Asia, Colonial and Post-Colonial Literature, Anthropology, Cultural Studies, History, Historiography, Politics, Race, Feminism, Language, Linguistics, Power, Political and Feminist Agendas, Popular Culture, Education, Women’s Writing, Religion, Multiculturalism, Globalisation, Migration. Chapter summary: 1. “Social Gender Stereotypes and their Implication in Hindi”, Anjali Pande, Jawaharlal Nehru University, New Delhi, India. This essay looks at the subtle ways in which gender identities are constructed and reinforced in India through social norms of language use. Language itself becomes a medium for perpetuating gender stereotypes, forcing its speakers to confirm to socially defined gender roles. Using examples from a classroom discussion about a film, this essay will highlight the underlying rigid male-female stereotypes in Indian society with their more obvious expressions in language. For the urban woman in India globalisation meant increased economic equality and exposure to changed lifestyles. On an individual level it also meant redefining gender relations and changing the hierarchy in man-­woman relationships. With the economic independence there is a heightened sense of liberation in all spheres of social life, a confidence to fuzz the rigid boundaries of gender roles. With the new films and media celebrating this liberated woman, who is ready to assert her sexual needs, who is ready to explode those long held notions of morality, one would expect that the changes are not just superficial. But as it soon became obvious in the course of a classroom discussion about relationships and stereotypes related to age, the surface changes can not become part of the common vocabulary, for the obvious reason that there is still a vast gap between the screen image of this new woman and the ground reality. Social considerations define the limits of this assertiveness of women, whereas men are happy to be liberal within the larger frame of social sanctions. The educated urban woman in India speaks in favour of change and the educated urban male supports her, but one just needs to scratch the surface to see the time tested formulae of gender roles firmly in place. The way the urban woman happily balances this emerging promise of independence with her gendered social identity, makes it necessary to rethink some aspects of looking at gender in a gradually changing, traditional society like India. 2. “The Linguistic Dimension of Gender Equality”, Alissa Tolstokorova, Kiev Centre for Gender Information and Education, Ukraine. The subject-matter of this essay is gender justice in language which, as I argue, may be achieved through the development of a gender-related approach to linguistic human rights. The last decades of the 20th century, globally marked by a “gender shift” in attitudes to language policy, gave impetus to the social movement for promoting linguistic gender equality. It was initiated in Western Europe and nowadays is moving eastwards, as ideas of gender democracy progress into developing countries. But, while in western societies gender discrimination through language, or linguistic sexism, was an issue of concern for over three decades, in developing countries efforts to promote gender justice in language are only in their infancy. My argument is that to promote gender justice in language internationally it is necessary to acknowledge the rights of women and men to equal representation of their gender in language and speech and, therefore, raise a question of linguistic rights of the sexes. My understanding is that the adoption of the Universal Declaration of Linguistic Rights in 1996 provided this opportunity to address the problem of gender justice in language as a human rights issue, specifically as a gender dimension of linguistic human rights. 3. “The Rebirth of an Old Language: Issues of Gender Equality in Kazakhstan”, Maria Helena Guimarães, Polytechnic Institute of Porto, Portugal. The existing language situation in Kazakhstan, while peaceful, is not without some tension. We propose to analyze here some questions we consider relevant in the frame of cultural globalization and gender equality, such as: free from Russian imperialism, could Kazakhstan become an easy prey of Turkey’s “imperialist dream”? Could these traditionally Muslim people be soon facing the end of religious tolerance and gender equality, becoming this new old language an easy instrument for the infiltration in the country of fundamentalism (it has already crossed the boarders of Uzbekistan), leading to a gradual deterioration of its rich multicultural relations? The present structure of the language is still very fragile: there are three main dialects and many academics defend the re-introduction of the Latin alphabet, thus enlarging the possibility of cultural “contamination” by making the transmission of fundamentalist ideas still easier through neighbour countries like Azerbaijan, Uzbekistan and Turkmenistan (their languages belong to the same sub-group of Common Turkic), where the Latin alphabet is already in use, and where the ground for such ideas shown itself very fruitful. 4. “Construction of Womanhood in the Bengali Language of Bangladesh”, Raasheed Mahmood; University of New South Wales, Sydney. The present essay attempts to explore the role of gender-based language differences and of certain markers that reveal the status accorded to women in Bangladesh. Discrimination against women, in its various forms, is endemic in communities and countries around the world, cutting across class, race, age, and religious and national boundaries. One cannot understand the problems of gender discrimination solely by referring to the relationship of power or authority between men and women. Rather one needs to consider the problem by relating it to the specific social formation in which the image of masculinity and femininity is constructed and reconstructed. Following such line of reasoning this essay will examine the nature of gender bias in the Bengali language of Bangladesh, holding the conviction that as a product of social reality language reflects the socio-cultural behaviour of the community who speaks it. This essay will also attempt to shed some light on the processes through which gender based language differences produce actual consequences for women, who become exposed to low self-esteem, depression and systematic exclusion from public discourse. 5. “Marriage in China as an expression of a changing society”, Elisabetta Rosado David, University of Porto, Portugal, and Università Ca’Foscari, Venezia, Italy. In 29 April 2001, the new Marriage Law was promulgated in China. The first law on marriage was proclaimed in 1950 with the objective of freeing women from the feudal matrimonial system. With the second law, in 1981, values and conditions that had been distorted by the Cultural Revolution were recovered. Twenty years later, a new reform was started, intending to update marriage in the view of the social and cultural changes that occurred with Deng Xiaoping’s “open policy”. But the legal reform is only the starting point for this case-study. The rituals that are followed in the wedding ceremony are often hard to understand and very difficult to standardize, especially because China is a vast country, densely populated and characterized by several ethnic minorities. Two key words emerge from this issue: syncretism and continuity. On this basis, we can understand tradition in a better way, and analyse whether or not marriage, as every social manifestation, has evolved in harmony with Chinese culture. 6. “The Other Woman in the Portuguese Colonial Empire: The Case of Portuguese India”, Maria de Deus Manso, University of Évora, Portugal. This essay researches the social, cultural and symbolic history of local women in the Portuguese Indian colonial enclaves. The normative Portuguese overseas history has not paid any attention to the “indigenous” female populations in colonial Portuguese territories, albeit the large social importance of these social segments largely used in matrimonial and even catholic missionary strategies. The first attempt to open fresh windows in the history of this new field was the publication of Charles Boxer’s referential study about Women in lberian Overseas Expansion, edited in Portugal only after the Revolution of 1975. After this research we can only quote some other fragmentary efforts. In fact, research about the social, cultural, religious, political and symbolic situation of women in the Portuguese colonial territories, from the XVI to the XX century, is still a minor historiographic field. In this essay we discuss this problem and we study colonial representations of women in the Portuguese Indian enclaves, mainly in the territory of Goa, using case studies methodologies. 7. “Heading East this Time: Critical Readings on Gender in Southeast Asia”, Clara Sarmento, Polytechnic Institute of Porto, Portugal. This essay intends to discuss some critical readings of fictional and theoretical texts on gender condition in Southeast Asian countries. Nowadays, many texts about women in Southeast Asia apply concepts of power in unusual areas. Traditional forms of gender hegemony have been replaced by other powerful, if somewhat more covert, forms. We will discuss some universal values concerning conventional female roles as well as the strategies used to recognize women in political fields traditionally characterized by male dominance. Female empowerment will mean different things at different times in history, as a result of culture, local geography and individual circumstances. Empowerment needs to be perceived as an individual attitude, but it also has to be facilitated at the macro­level by society and the State. Gender is very much at the heart of all these dynamics, strongly related to specificities of historical, cultural, ethnic and class situatedness, requiring an interdisciplinary transnational approach.

Environmental policies in an international mixed duopoly

The purpose of this paper is to study the effects of environmental and trade policies in an international mixed duopoly serving two markets. We suppose that the firm in the home country is a welfare-maximizing public firm, while the firm in the foreign country is its own profit-maximizing private firm. We find that the environmental tax can be a strategic instrument for the home government to distribute production from the foreign private firm to the home public firm. An additional effect of the home environmental tax is the reduction of the foreign private firm's output for local consumption, thereby expanding the foreign market for the home public firm.

Electrolipólise mediada por TENS e microcorrente em associação com exercício físico

Introdução: A gordura visceral e subcutânea do abdómen poderá aumentar o risco de diferentes patologias. Objectivo: Verificar se a lipólise induzida pela corrente eléctrica, é eficaz na redução de massa gorda. Métodos: Vinte e três mulheres foram divididas em três grupos: controlo só com exercício físico, experimental com TENS e exercício físico e experimental com microcorrente e exercício físico. Resultados: Nos grupos experimentais, aumentaram os triglicerídeos (p<0,05), diminuiu a prega supra-ilíca (p>0,05) e observaram-se valores tendencialmente menores de parâmetros específicos e globais. No grupo da Microcorrente diminuiu a prega abdominal (p>0,05). Conclusão: A electrolipólise poderá ter efeito coadjuvante ao exercício físico, na redução da massa gorda.

Aspectos teóricos y prácticos de la interpretación de congresos de medicina

Los congresos de medicina se destacan actualmente como uno de los eventos multilingües que se celebran con más frecuencia en el panorama internacional. Recurrir a los servicios de interpretación se revela como un hecho habitual entre los organizadores de estos encuentros, especialmente en determinados ámbitos nacionales. Por consiguiente, los congresos de medicina brindan grandes posibilidades laborales a los intérpretes de conferencias, sobre todo a aquellos cuya combinación lingüística es inglés-español, dado que el inglés se define, sin lugar a dudas, como la lengua por excelencia de la comunicación médica. No obstante, a pesar de esta demanda creciente en nuestra sociedad actual, los planteamientos académicos y profesionales siguen siendo, en gran medida, teóricos e intuitivos, fruto de experiencias personales, carentes en la mayoría de los casos de un respaldo empírico. Para corroborar o descartar ciertas presuposiciones establecidas a priori por estudiosos de la interpretación especializada, como pueden ser el uso de determinadas fuentes documentales y métodos de preparación, la evaluación de determinados parámetros de calidad o el nivel de especialización del intérprete, nos servimos de unas medidas de valoración retrospectivas en intérpretes profesionales especializados en congresos de medicina para verificar nuestro objetivo fundamental: en qué medida se alejan las teorías establecidas de la práctica profesional.

Recuperação do calor de um efluente primário para aquecimento de lamas de um reactor anaeróbio

O presente trabalho tem como principal objectivo o estudo da possibilidade de recuperação de calor de um efluente proveniente do tratamento primário da fábrica do grupo Portucel Soporcel (fábrica produtora de pasta de papel), para o aquecimento da corrente de lamas do digestor anaeróbio da SimRia S.A. – ETAR Norte, (ambas localizadas em Cacia, distrito de Aveiro). A solução consiste na implementação de um sistema de permuta térmica entre estas duas correntes, constituído fundamentalmente por dois permutadores de placas em espiral, montados em paralelo que operam em contra-corrente. Segundo este novo sistema de aquecimento, as lamas abandonam o digestor anaeróbio da mesma ETAR a um caudal de 110 m3/h, que se dividirá em duas linhas, sendo admitidas em cada permutador a 55 m3/h e a uma temperatura de 32 ºC regressando ao digestor a uma temperatura de 37 ºC (temperatura óptima a que ocorre a digestão anaeróbia das lamas). O efluente disponível, abandona o tratamento primário da Portucel, a 45 ºC e é encaminhado até aos permutadores da SimRia S.A., onde vai trocar calor com as lamas e regressa à Portucel a 40ºC, sendo admitido nas torres de arrefecimento da fábrica de papel. A nova instalação proposta pretende substituir a actual existente na ETAR em causa, em que a corrente de água que aquece as lamas, circula num circuito fechado entre um único permutador e uma caldeira, alimentada com o biogás que se produz no digestor anaeróbio, e que é responsável pelo controlo da temperatura da corrente de água. Pretende-se que a implementação deste novo método de aquecimento de lamas seja uma alternativa económica relativamente ao actual sistema, uma vez que vai substituir a corrente de biogás alimentada à caldeira podendo este recurso ser transformado em energia eléctrica e posteriormente comercializada. A análise financeira realizada ao projecto demonstrou que o projecto é rentável, uma vez que, a diferença entre todos ganhos e custos ao fim dos 10 anos de vida útil estimados é de cerca de 150 000,0 €. O período de retorno do investimento é alcançado no final dos primeiros 6 anos e a taxa interna de rentabilidade obtida foi de 36 %. Posteriormente incluiu-se neste estudo a possibilidade de tratamento das lamas geradas na fábrica da Portucel na ETAR da SimRia recorrendo a um terceiro digestor. Conclui-se que se trata duma opção vantajosa, uma vez que permite obter um caudal de biogás 44 m3/h, que convertido em potência permite obter 150 kW que poderá ser aproveitado para produção de energia ou comercializado gerando uma receita adicional de 130 000,0 €/ano para as entidades envolvidas.
