Teaching Intercultural Communication in Foreign Language Education through Video Conferencing

Since 1980s, Western linguists and specialists on second language acquisition have emphasized the importance of enhancing students’ intercultural communication competence in foreign language education. At the same time, the demand for intercultural communicative competence increased along with the advances of communication technology with its increasingly global reach and the process of globalization itself.In the field of distance language education, these changes have resulted in a shift of focus from the production and distribution of learning materials towards communication and learning as a social process, facilitated by various internet-based platforms. The current focus on learners interacting and communicating synchronously trough videoconferencing is known as the fourth generation of distance language education. Despite the fact that teaching of Chinese as a foreign language (CFL) faces the same or even greater challenges as teaching other languages, the intercultural communication perspective is still quite a new trend in CFL and its implementation and evaluation are still under development. Moreover, the advocates of the new trends in CFL have so far focused almost exclusively on classroom-based courses, neglecting the distance mode of CFL and leaving it as an open field for others to explore. In this under-researched context, Dalarna University (Sweden), where I currently work, started to provide web-based courses of the Chinese language in 2007. Since 2010, the Chinese language courses have been available only in the distance form, using the same teaching materials as the previous campus-based courses. The textbooks used in both settings basically followed the functional nationalism approach. However, in order to catch up with the main trend of foreign-language education, we felt a need to implement the cross-cultural dimension into the distance courses as well. Therefore in 2010, a pilot study has been carried out to explore opportunities and challenges for implementing a cross-cultural perspective into existing courses and evaluating the effectiveness of this implementation based on the feedback of the students and on the experience of the teacher/researcher.

What affects recognition most – wrong wordstress or wrong word accent?

In an attempt to find out which of the two Swedish prosodic contrasts of 1) wordstress pattern and 2) tonal word accent category has the greatest communicative weight, a lexical decision experiment was conducted: in one part word stress pattern was changed from trochaic to iambic, and in the other part trochaic accentII words were changed to accent I.Native Swedish listeners were asked to decide whether the distorted words werereal words or ‘non-words’. A clear tendency is that listeners preferred to give more‘non-word’ responses when the stress pattern was shifted, compared to when wordaccent category was shifted. This could have implications for priority of phonological features when teaching Swedish as a second language.

What Culture? : Cultural representations in English as a foreign language textbooks

Teaching the cultural aspect of foreign language education is a complex and sometimes difficult task, especially since English has become an international language used in different settings and contexts throughout the world. Building on the idea that the spread of the English language and its international status in the world has made English an important school subject to develop students’ cross-cultural and intercultural awareness, this paper has studied what research reveals about the influence this has had on cultural representations in English as a Foreign Language (EFL) textbooks. Findings from a systematic literature review that analyzed four different international studies on the topic are presented. The study showed that EFL textbooks often present stereotypical and overgeneralized representations of culture and that the cultural aspect of EFL education is not adequately addressed since focus tends to lean towards language proficiency. Results also indicated that though steps are made to include cultural representations from different international contexts, the target culture of countries where English is the first language remains dominant in EFL textbooks. The findings are discussed in correlation with the Swedish national curriculum and syllabus.

Product placement in movies: a cross cultural study between Brazil and the USA

The broader objective of this study undertaking can briefly be articulated in particulate aims as follows: to measure the attitudes of consumers regarding the brand displayed by this strategy as well as to highlight recall, recognition and purchase intentions generated by product placement on consumers. In addition, check the differences and similarities between the behavior of Brazilian and American consumers caused by the influence of product placements. The study was undertaken targeting consumer audience in Brazil and the U.S. A rang3 modeling set ups were performed in order to realign study instruments and hypothesis towards the research objectives. This study gave focus on the following hypothesized models. H1: Consumers / Participants who viewed the brands / products in the movie have a higher brand / product recall compared to the consumers / participants who did not view the brands / products in the movie. H2: US Consumers / Participants are able to recognize and recall brands / products which appear in the background of the movie than Brazil. H3: Consumers / participants from USA are more accepting of product placements compared to their counterparts in Brazil. H4: There are discernible similarities in consumer / participant brand attitudes and purchase intentions in consumers / participants from USA and Brazil in spite of the fact that their country of origin is different. Cronbach’s Alpha Coefficient ensured the reliability of survey instruments. The study involved the use of the Structural Equation Modeling (SEM) for the hypothesis testing. This study used the Confirmatory Factor Analysis (CFA) to assess both the convergent and discriminant validities instead of using the Exploratory Factor Analysis (EFA) or the Principal Component Analysis (PCA). This reinforced for the use of the regression Chi Square and T statistical tests in further. Only hypothesis H3 was rejected, the rest were not. T test provided insight findings on specific subgroup significant differences. In the SEM testing, the error variance for product placement attitudes was negative for both the groups. On this The Heywood Case came in handy to fix negative values. The researcher used both quantitative and qualitative approach where closed ended questionnaires and interviews respectively were used to collect primary data. The results were additionally provided with tabulations. It can be concluded that, product placement varies markedly in the U.S. from Brazil based on the influence a range of factors provided in the study. However, there are elements of convergence probably driven by the convergence in technology. In order, product placement to become more competitive in the promotional marketing, there will be the need for researchers to extend focus from the traditional variables and add knowledge on the conventional marketplace factors that is the sell-ability of the product placement technologies and strategies.

Plasmodium falciparum: sequence diversity and antibody recognition of the Merozoite surface protein-2 (MSP-2) in Brazilian Amazonia

The merozoite surface protein-2 (MSP-2) of Plasmodium falciparum comprises repeats flanked by dimorphic domains defining the allelic families FC27 and IC1. Here, we examined sequence diversity at the msp-2 locus in Brazil and its impact on MSP-2 antibody recognition by local patients. Only 25 unique partial sequences of msp-2 were found in 61 isolates examined. The finding of identical msp-2 sequences in unrelated parasites, collected 6-13 years apart, suggests that no major directional selection is exerted by variant-specific immunity in this malaria-endemic area. To examine antibody cross-reactivity, recombinant polypeptides derived from locally prevalent and foreign MSP-2 variants were used in ELISA. Foreign IC1-type variants, such as 3D7 (currently tested for human vaccination), were less frequently recognized than FC27-type and local IC1-type variants. Antibodies discriminated between local and foreign IC1-type variants, but cross-recognized structurally different local IC1-type variants. The use of evolutionary models of MSP-2 is suggested to design vaccines that minimize differences between local parasites and vaccine antigens. (C) 2004 Elsevier B.V. All rights reserved.

Cross-cultural differences for three visual memory tasks in Brazilian children

Norms for three visual memory tasks, including Corsi's block tapping test and the BEM 144 complex figures and visual recognition, were developed for neuropsychological assessment in Brazilian children. The tasks were measured in 127 children ages 7 to 10 years from rural and urban areas of the States of São Paulo and Minas Gerais. Analysis indicated age-related but not sex-related differences. A cross-cultural effect was observed in relation to copying and recall of Complex pictures. Different performances between rural and urban children were noted. © Perceptual and Motor Skills 2005.

Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes

This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ACF are widely used in signal processing. This work shows some features and problems in using these methods, as well as some improvements developed to increase their performance. © 2008 IEEE.

Robust and fast vowel recognition using optimum-path forest

The applications of Automatic Vowel Recognition (AVR), which is a sub-part of fundamental importance in most of the speech processing systems, vary from automatic interpretation of spoken language to biometrics. State-of-the-art systems for AVR are based on traditional machine learning models such as Artificial Neural Networks (ANNs) and Support Vector Machines (SVMs), however, such classifiers can not deal with efficiency and effectiveness at the same time, existing a gap to be explored when real-time processing is required. In this work, we present an algorithm for AVR based on the Optimum-Path Forest (OPF), which is an emergent pattern recognition technique recently introduced in literature. Adopting a supervised training procedure and using speech tags from two public datasets, we observed that OPF has outperformed ANNs, SVMs, plus other classifiers, in terms of training time and accuracy. ©2010 IEEE.

Automatic landslide recognition through Optimum-Path Forest

In this paper we shed light over the problem of landslide automatic recognition using supervised classification, and we also introduced the OPF classifier in this context. We employed two images acquired from Geoeye-MS satellite at March-2010 in the northwest (high steep areas) and north sides (pipeline area) covering the area of Duque de Caxias city, Rio de Janeiro State, Brazil. The landslide recognition rate has been assessed through a cross-validation with 10 runnings. In regard to the classifiers, we have used OPF against SVM with Radial Basis Function for kernel mapping and a Bayesian classifier. We can conclude that OPF, Bayes and SVM achieved high recognition rates, being OPF the fastest approach. © 2012 IEEE.

Levantamento, análise e descrição de elementos paralinguísticos do português espontâneo

A fala apresenta aspectos paralinguísticos que não pertencem ao código linguístico convencional, mas contribuem significativamente para a unidade temática do discurso, Essas realizações se constituem em enunciados não-lexicalizados que funcionam que funcionam como atos de fala completos nas interações comunicativas interpessoais. Sobre essas emissões não-verbais, Campbell (2002a, 2002b, 2003 e 2004), Maekawa (2004), Fujie et. al (2004), Hoult (2004), Key (1958) apud Steimberg (1988) postulam que elas constribuem para a manifestação da fala expressiva. Para os autores, é justamente o fenômeno da paralinguagem que sinaliza informações sobre atitudes, opiniões e emoções do falante em relação ao interlocutor ou ao tópico discursivo. Nesse sentido, investigamos, neste trabalho, as manifestações paralinguísticas recorrentes em conversas informais para demonstrarmos seu papel expressivo na linguagem falada. Para tanto, fizemos um levantamento de 450 ocorrências de elementos paralinguísticos no processo de transcrição de amostras de falas do Português Regional Paraense produzidas em situações reais de conversação. Pressupondo que essas realizações não-verbais são caracterizadas por variações prosódicas, nós as submetemos a uma análise fonética por meio do software PRAAT. A partir dessa análise, constatamos a contribuição de duas propriedades: a frequência fundamental (F0) e o tempo de emissão, para a manifestação expressiva dos elementos paralinguísticos no discurso falado. Além disso, identificamos também a silabação como uma propriedade comum às realizações sonoras focalizadas. Após o processo de análise, fizemos a descrição do uso e do funcionamento desses elementos nas conversas, bem como da contribuição deles para a manifestação da fala expressiva. Os resultados nos mostram que os elementos paralinguísticos, além de contribuírem para a fluência do discurso falado, desempenham a função de sinalizar compreensão, interesse e/ou atenção, gerenciar relações interpessoais e expressar emoções, atitudes e afeto.

Envelhecimento, linguagem e memória visuo-espacial: um estudo comparativo exploratório do desempenho humano em testes neuropsicológicos selecionados

O reconhecimento dos limites entre o envelhecimento normal e o patológico é essencial para a adoção de políticas de saúde baseadas em evidências para o grupo etário acima de 65 anos. Este estudo é parte de um esforço sistemático que o grupo de pesquisa do Laboratório de Investigações em Neurodegeneração e Infecção da Universidade Federal do Pará tem feito para fornecer informações translacionais sobre a neurobiologia do envelhecimento normal e alterada. A meta principal em longo prazo é permitir políticas públicas para o envelhecimento saudável na Região Amazônica. No presente trabalho investigamos os efeitos do envelhecimento sobre os desempenhos em testes neuropsicológicos selecionados para avaliar aprendizagem, memória e alterações de linguagem. 29 adultos jovens (29,9 ± 1,06 anos) e 31 idosos (74,1 ± 1,15 anos) saudáveis foram submetidos aos testes e os resultados de seus desempenhos foram comparados por testes paramétricos e estatística multivariada. Uma anamnese e uma variedade de testes cognitivos, incluindo Mini Exame do Estado Mental, tarefas visuo-espaciais de aprendizagem e de memória da bateria de testes neuropsicológicos automatizados - CANTAB e testes de linguagem incluindo fluência verbal semântica e fonológica, teste de nomeação de Boston reduzido, performance narrativa utilizando a figura “o roubo dos biscoitos” e alguns testes da Bateria Montreal de Comunicação - MAC. O programa BioEstat versão 5.0 e o pacote estatístico SPSS foram utilizados para a análise. O teste paramétrico t de Student ou o não paramétrico de Mann-Whitney foram aplicados para detectar diferenças significativas (fixadas em valores de p <0,05). Os grupos foram pareados por escolaridade e incluiu homens e mulheres. A análise das subcategorias que compõem o MEEM mostrou diferença significativa apenas na recuperação da memória de evocação de lista de palavras, em que o grupo de idosos apresentou pior desempenho em comparação com o grupo de jovens. Foram encontradas diferenças estatisticamente significativas entre os desempenhos de idosos e jovens adultos nos seguintes testes de linguagem: 1) Nomeação de Boston, 2) Testes de Narrativa, 3) Metáforas; 4) Prosódia Emocional e Linguística. Em comparação com os adultos jovens, indivíduos idosos apresentaram pior desempenho em 10 medidas diferentes nos testes de memória visuo-espacial e de aprendizagem do CANTAB. Distâncias Euclidianas e análise discriminante obtidas a partir do CANTAB e dos testes de linguagem demonstraram que os primeiros distinguem os grupos com maior resolução. Os efeitos do envelhecimento sobre o desempenho nos testes neuropsicológicos selecionados revelam que a Bateria CANTAB, empregada para testar a memória visuo-espacial, é mais sensível e discrimina melhor a formação de subgrupos tanto no grupo de adultos jovens quanto no grupo de idosos. Por essa razão sugerimos que a aplicação em larga escala de testes selecionados da bateria CANTAB, tanto em estudos transversais como em longitudinais, vai aumentar nossa capacidade de resolução na distinção dos limites entre o envelhecimento normal e o patológico.
