Substituição na produção de /ɵ/ e /ð/ por falantes do português: uma análise não linear

Trata o presente estudo da produção das fricativas interdentais da língua inglesa por falantes do português brasileiro (PB), aprendizes de Inglês como língua estrangeira, (English as a Foreign Language – EFL) nos Cursos Livres de Línguas Estrangeiras mantidos pela Universidade Federal do Pará. O objetivo deste estudo é investigar as possibilidades de ocorrência de substituições para as fricativas interdentais surda e sua contraparte sonora em posições de onset e coda silábica, os resultados são analisados com base na Fonologia de Geometria de Traços (Clements e Hume, 1995). A coleta de dados foi realizada junto a um grupo de vinte e dois alunos, sendo 12 alunos do terceiro nível e 10 alunos do sétimo nível. Pretende-se fazer a representação detalhada do processo de substituição que falantes do português brasileiro (PB), aprendizes de inglês como segunda língua (ESL), realizam especificamente para os segmentos fricativos interdentais da língua inglesa em suas versões surda e sonora /Ɵ/ e /ð/, no processo de aquisição da fonologia desta língua. Diferentes tipos de segmentos foram encontrados em nossa pesquisa como resultado das substituições, quais sejam: [t],[tʃ],[d],[f] e [s] para a fricativa interdental surda /Ɵ/ e [t],[d],[s],[f],[v] e [tʃ] para a fricativa interdental sonora /ð/. Os tipos predominantes de processos observados foram: (a) Fortição, (b) Posteriorização (c) Sonorização (d) Palatalização (e) Labialização (f) Epêntese e (g) Ressilabificação. Todos resultando de um processo anterior chamado Nativização.

O retorno na produção escrita e suas influências na motivação para a aprendizagem de inglês

Pesquisas na área do ensino/aprendizagem da produção escrita em língua estrangeira têm envolvido os estudos sobre o erro apresentado por alunos, incluindo, geralmente, o como e por que fornecer correção a esses erros. Alguns sugerem que a correção desempenha papel tão importante quanto os erros, na aprendizagem, pois a forma como ela é feita pode beneficiar ou prejudicar o desenvolvimento de seus alunos. No intuito de investigar a(s) forma(s) como professores de língua inglesa fornecem a correção de erros escritos a seus alunos, assim como quais os efeitos dessa intervenção na motivação para aprender uma língua estrangeira é que nos propusemos desenvolver esta pesquisa. Para tanto, o referencial teórico utilizado baseia-se nas teorias sobre erro e retorno, escrita em segunda língua (L2) e motivação e retorno motivacional, em especial naquelas encontradas em Figueiredo (2001, 2005), Ferris (2004), Raimes (1991) e Dörnyei (2000-2011, 2001, 2010). A investigação é de caráter observatório não-participante, descritiva e se deu em uma turma do curso de Letras Língua Inglesa, da Universidade Federal do Pará, campus de Marabá. São sujeitos da pesquisa professores deste curso e um grupo de estudantes da graduação. Como instrumentos de coleta de dados, utilizamos observação de aulas, questionários e produção escrita dos alunos. Os resultados obtidos nos mostram que a maior parte dos movimentos corretivos partem do professor. No entanto, percebemos que, quando os alunos participam do processo, há uma maior aceitação, o que pode resultar em possíveis melhorias para a escrita e para a aprendizagem da L2 propriamente dita.

A abordagem do voseo em materiais didáticos brasileiros de ensino do espanhol como língua estrangeira

This work discusses the importance of the language varieties in the Spanish language to the process of teaching and learning Spanish as a foreign language (ELE), focusing on the approach, ie, how to deal with the phenomenon voseo in Brazilian textbooks. It presents a brief historical overview on the arising of this language and its implementation in Latin America. From an educational approach that values a good development of communicative competence, it’s driven to a presentation of the Spanish schoolbooks selected by PNLD for the year 2012, as well as an observation of activities that demonstrate the phenomenon called voseo, in other words, the use of the variety of the pronoun vos instead of tú for the treatment of the second person. Given the vast range of Spanish courses as a foreign language for high school students, and the growing interest of young people in learning a second language, this study addresses the importance of developing the communicative competence of a foreign language

Vozeamento na pronúncia de uma língua estrangeira: descrição de desvios comuns e como eles afetam o aprendizado do inglês

This paper analyzes voicing occurrences on the coda of Portuguese and English words pronounced by Brazilian speakers. The aim of this kind of analysis is to describe how voicing occurrences affect the realization and perception of foreign words. It was noted that there is a recurrence on the use of unvoiced coda in Portuguese, which was assumed to happen also in English when Brazilian Portuguese speakers uses it as a second language. The recordings were analyzed through Praat, software that generates waveforms and spectrograms, allowing segments to be divided and phonetically transcribed. The analysis proved the assumption to be true, concluding that speakers who had their speeches recorded produced unvoiced codas in fact. Conclusions concerning this take into consideration that, considering how minimal pairs in English can be produced based on coda voicing, there is a possible communication difficulty Brazilians may face due to this fact. But it goes by unnoticed, because this process sounds so natural it hardly is taken as a problem source

A interlíngua e o alinhamento léxico-conceitual da base de dados bilíngue REBECA

In the architecture of a natural language processing system based on linguistic knowledge, two types of component are important: the knowledge databases and the processing modules. One of the knowledge databases is the lexical database, which is responsible for providing the lexical unities and its properties to the processing modules. The systems that process two or more languages require bilingual and/or multilingual lexical databases. These databases can be constructed by aligning distinct monolingual databases. In this paper, we present the interlingua and the strategy of aligning the two monolingual databases in REBECA, which only stores concepts from the “wheeled vehicle” domain.

A norma-padrão Europeia e a mudança linguística na Escola Moçambicana

In Mozambique, the portuguese language is considered the official language, second language, national language and competes with more than twenty Bantu languages spoken by the majority of population. The standard norm lose away their floor to the Mozambican Portuguese which carries own characteristics pertaining to the sociolinguistic context of the country. Schools attempt their best, but they cannot teach the European standard due the multilingual and Portuguese contact with African languages, a fact that is reflected in the media and in the literature through their oral and written forms. These difficulties result in high rates of failures due to problems encountered in using the European standard by teachers and writers who prepare the school books. This research suggests the standardization of the Mozambican variant as well as the preparation of dictionaries and grammars illustrating the sociolinguistic reality of Mozambique in order to improve the quality of education. It also emphasizes the need for a self-esteem spirit on Mozambicans in general as a conduit to eliminate the soaring bias that Mozambicans can not speak portuguese language

Extractive summarization using complex networks and syntactic dependency

The realization that statistical physics methods can be applied to analyze written texts represented as complex networks has led to several developments in natural language processing, including automatic summarization and evaluation of machine translation. Most importantly, so far only a few metrics of complex networks have been used and therefore there is ample opportunity to enhance the statistics-based methods as new measures of network topology and dynamics are created. In this paper, we employ for the first time the metrics betweenness, vulnerability and diversity to analyze written texts in Brazilian Portuguese. Using strategies based on diversity metrics, a better performance in automatic summarization is achieved in comparison to previous work employing complex networks. With an optimized method the Rouge score (an automatic evaluation method used in summarization) was 0.5089, which is the best value ever achieved for an extractive summarizer with statistical methods based on complex networks for Brazilian Portuguese. Furthermore, the diversity metric can detect keywords with high precision, which is why we believe it is suitable to produce good summaries. It is also shown that incorporating linguistic knowledge through a syntactic parser does enhance the performance of the automatic summarizers, as expected, but the increase in the Rouge score is only minor. These results reinforce the suitability of complex network methods for improving automatic summarizers in particular, and treating text in general. (C) 2011 Elsevier B.V. All rights reserved.

The lexical approach: collocability, fluency and implications for teaching

[EN] [EN] The lexical approach identifies lexis as the basis of language and focuses on the principle that language consists of grammaticalised lexis. in second language acquisition, over the past few years, this approach has generated great interest as an alternative to traditional grammar-based teaching methods. From a psycholinguistic point of view, the lexical approach consists of the capacity of understanding and producing lexical phrases as non-analysed entities (chunks). A growing body of literature concerning spoken fluency is in favour of integrating automaticity and formulaic language units into classroom practice. in line with the latest theories on SlA, we recommend the inclusion of a language awareness component as an integral part of this approach. The purpose is to induce what Schmidt (1990) calls noticing , i.e., registering forms in the input so as to store themin memory. This paper, which is in keeping with the interuniversity Research Project “Evidentialityin a multidisciplinary corpus of English research papers” of the University of las Palmas de Gran Canaria, provides a theoretical overview on theresearch of this approach taking into account both the methodological foundationson the subject and its pedagogical implications for SLA

The secrets of publishing your article in Journal of Geophysical Research (Oceans)

[EN] The editorial and review processes along the road to publication are described in general terms. The construction of a well-prepared article and the manner in which authors may maximise the chances of success at each stage of the process towards final publication are explored. The most common errors and ways of avoiding them are outlined. Typical problems facing an author writing in English as a second language, including the need for grammatical precision and appropriate style, are discussed. Additionally, the meaning of plagiarism, self-plagiarism and duplicate publication is explored. Critical steps in manuscript preparation and response to reviews are examined. Finally, the relation between writing and reviewing is outlined, and it is shown how becoming a good reviewer helps in becoming a successful author

Research and theory driven insights: ten suggestions for L2 reading instruction

[EN]Research and theory on second language reading has reached heightened dimensions in recent years. It is through reading that learners access much information concerning the target language and culture, and consequently reading is an important part of almost all language programs across stages of acquisition. The purpose of this article is to offer informed suggestions for the foreign language instructor of reading. The ideas given in this paper constitute a collaborative project that developed as part of a graduate seminar on L2 Reading and Writing taught at Washington University in St. Louis.

Educazione alla cittadinanza per cittadini immigrati adulti. Il contributo della formazione linguistico-giuridica all'acquisizione di competenze di cittadinanza in lingua seconda

The research examines which cultural and linguistic instruments can be offered to provide adult migrants with formative access to citizenship competences. Starting from the questions: How can individuals of all community groups present in a nation-state acquire high standards of linguistic, sociolinguistic and discourse competences in order to be fully integrated, that is to participate and be included in social activities in the public domain such as work and institutional environments? How are these competencies developed in an educational context? How do adult migrants behave linguistically in this context, according to their needs and motivations? The research hypothesis aimed at outlining a formative project of citizenship education targeted at adult foreign citizens, where a central role is assigned both to law education and linguistic education. Acoordingly, as the study considered if the introduction of a law programme in a second language course could be conceived as an opportunity to further the access to active citizenship and social participation, a corpus of audiodata was collected in law classes of an Italian adult professional course attended by a 50% of foreign students. The observation was conducted on teacher and learner talk and learner participation in classroom interaction when curriculum legal topics were introduced and discussed. In the classroom law discourse two dimensions were analyzed: the legal knowledge construction and the participants’ interpersonal and identity construction. From the analysis, the understanding is that drawn that law classes seem to represent an educational setting where foreign citizens have an opportunity to learn and practise citizenship. The social and pragmatic approach to legal contents plays a relevant role, in a subject which, in non-academic contexts, loses its technical specificity and refers to law as a product of social representation. In the observed educational environment, where students are adults who bring into the classroom multiple personal and social identities, legal topics have the advantage of increasing adult migrants’ motivation to ‘go back to school’ as they are likely to give hints, if not provide solutions, to problems relating to participation in socio-institutional activities. At the same time, these contents offer an ideal context where individuals can acquire high discourse competences and citizenship skills, such as agency and critical reflection. Besides, the analysis reveals that providing adult learners with materials that focus on rights, politics and the law, i.e. with materials which stimulate discussion on concerns affecting their daily lives, is welcomed by learners themselves, who might appreciate the integration of these same topics in a second language course.

L'italiano di apprendenti lituani: elementi acquisizionali e implicazioni didattiche

La ricerca, che ha per oggetto lo studio dell’apprendimento guidato dell’italiano come lingua seconda da parte di apprendenti lituani, si articola in quattro capitoli. I primi due costituiscono il quadro teorico della ricerca, dedicando il primo ai fondamenti teorici e ricerche empiriche in generale e il secondo alle ricerche sull’apprendimento dell’italiano come L2. Nel terzo capitolo viene presentata la metodologia della ricerca, mentre nel quarto capitolo vengono presentati i risultati, concentrandosi in particolare sull’ortografia, sulla morfologia del nome, sulla categoria del verbo e sugli aspetti sintattici.In base ai risultati conseguiti, che in parte confermano i percorsi acquisizionali rilevati in contesto di apprendimento spontaneo, vengono all’ultimo suggerite alcune proposte applicative.

BabelNet e il problema della Word Sense Disambiguation

La Word Sense Disambiguation è un problema informatico appartenente al campo di studi del Natural Language Processing, che consiste nel determinare il senso di una parola a seconda del contesto in cui essa viene utilizzata. Se un processo del genere può apparire banale per un essere umano, può risultare d'altra parte straordinariamente complicato se si cerca di codificarlo in una serie di istruzioni esguibili da una macchina. Il primo e principale problema necessario da affrontare per farlo è quello della conoscenza: per operare una disambiguazione sui termini di un testo, un computer deve poter attingere da un lessico che sia il più possibile coerente con quello di un essere umano. Sebbene esistano altri modi di agire in questo caso, quello di creare una fonte di conoscenza machine-readable è certamente il metodo che permette di affrontare il problema in maniera più diretta. Nel corso di questa tesi si cercherà, come prima cosa, di spiegare in cosa consiste la Word Sense Disambiguation, tramite una descrizione breve ma il più possibile dettagliata del problema. Nel capitolo 1 esso viene presentato partendo da alcuni cenni storici, per poi passare alla descrizione dei componenti fondamentali da tenere in considerazione durante il lavoro. Verranno illustrati concetti ripresi in seguito, che spaziano dalla normalizzazione del testo in input fino al riassunto dei metodi di classificazione comunemente usati in questo campo. Il capitolo 2 è invece dedicato alla descrizione di BabelNet, una risorsa lessico-semantica multilingua di recente costruzione nata all'Università La Sapienza di Roma. Verranno innanzitutto descritte le due fonti da cui BabelNet attinge la propria conoscenza, WordNet e Wikipedia. In seguito saranno illustrati i passi della sua creazione, dal mapping tra le due risorse base fino alla definizione di tutte le relazioni che legano gli insiemi di termini all'interno del lessico. Infine viene proposta una serie di esperimenti che mira a mettere BabelNet su un banco di prova, prima per verificare la consistenza del suo metodo di costruzione, poi per confrontarla, in termini di prestazioni, con altri sistemi allo stato dell'arte sottoponendola a diversi task estrapolati dai SemEval, eventi internazionali dedicati alla valutazione dei problemi WSD, che definiscono di fatto gli standard di questo campo. Nel capitolo finale vengono sviluppate alcune considerazioni sulla disambiguazione, introdotte da un elenco dei principali campi applicativi del problema. Vengono in questa sede delineati i possibili sviluppi futuri della ricerca, ma anche i problemi noti e le strade recentemente intraprese per cercare di portare le prestazioni della Word Sense Disambiguation oltre i limiti finora definiti.
