A comunicação intercultural ao nível da intervenção pedagógica no ensino do português como língua estrangeira a alunos chineses na China

A globalização aproxima os povos: o mundo chinês e o mundo português nunca tiveram uma relação tão estreita como a atual. Apesar de os portugueses terem ido os primeiros ocidentais a entrar na China com a chegada de Jorge Álvares a uma ilha chinesa, em 1513, e os últimos ocidentais a deixar o governo de um território chinês, com a transferência da administração portuguesa de Macau para a China a 20 de dezembro de 1999, nunca haviam sido registados, nos últimos séculos, grandes contatos ou intercâmbios comerciais e culturais entre a China e Portugal e entre o mundo chinês e o mundo lusófono, em comparação com os contatos entre o mundo chinês e outros mundos ocidentais: como o inglês, o francês, o alemão e o espanhol. Os objetivos gerais desta investigação são três: 1 - Reconhecer o papel do desenvolvimento da competência omunicativa intercultural no contexto do ensino-aprendizagem do português como LE na China. 2 - Promover o desenvolvimento da competência comunicativa intercultural dos alunos chineses no processo de aprendizagem da língua portuguesa na China. 3 - Analisar os métodos pedagógicos e de integração curricular para apoiar e desenvolver um ensino mais eficaz do português como LE na China. O desenvolvimento do nosso trabalho articula-se em duas áreas científicas: Ciências da Linguagem e Ciências da Educação. A abordagem metodológica utilizada é o estudo de caso, com recolha de dados primários realizada através de questionários, entrevistas e observação participante em profundidade, que permitiu a confirmação e/ou refutação das hipóteses levantadas, privilegiando a metodologia qualitativa. Os resultados permitem estabelecer uma relação significativa, do ponto de vista pedagógico, entre a comunicação intercultural na educação e as práticas pedagógicas desenvolvidas no ensino do português como língua estrangeira na China. Contudo e de acordo com a nossa pesquisa, o maior problema que impede as práticas pedagógicas para desenvolver as competências comunicativas no ensino, é a falta de materiais didáticos com estrutura para elaborar um programa de atividades coerentes e complementares nas aulas.

Inserción de Colombia en el mercado de China, hacia un tratado de libre comercio Colombia – China.

El presente trabajo busca evaluar las oportunidades y amenazas que se pueden generar a causa de la creación de un Tratado de Libre Comercio con China, identificando así el impacto que tendrían dichas alianzas sobre el desarrollo económico del país y sobre la competitividad en la región. A partir del análisis de las relaciones comerciales y particularidades de las dos economías, se tendrá en cuenta variables como la reducción del crecimiento económico de China que ha venido experimentando en los últimos años respecto al crecimiento que ha venido ganando poco a poco Colombia. Para ello, se realizó una investigación con base en información relevante de los últimos 5 años, obtenida de diferentes fuentes. Entre estas se destaca el Plan Nacional de Desarrollo (2014- 2018), estadísticas del DANE, portales de análisis económico, entrevistas, revistas indexadas, entre otras. Este compendio de fuentes permitirá evaluar el comportamiento actual de la economía en Colombia y China, así como de las perspectivas económicas de cada país para los próximos años en relación al comercio exterior. Con esto se logrará evaluar la factibilidad, así como las ventajas y desventajas que debería asumir Colombia al firmar un Tratado de Libre Comercio con su segundo socio comercial más importante.

A 20-day period standing oscillation in the northern winter stratosphere

Observations of the ozone profile by a ground-based microwave radiometer in Switzerland indicate a dominant 20-day oscillation in stratospheric ozone, possibly related to oscillations of the polar vortex edge during winter. For further understanding of the nature of the 20-day oscillation, the ozone data set of ERA Interim meteorological reanalysis is analyzed at the latitude belt of 47.5° N and in the time from 1979 to 2010. Spectral analysis of ozone time series at 7 hPa indicates that the 20-day oscillation is maximal at two locations: 7.5° E, 47.5° N and 60° E, 47.5° N. Composites of the stream function are derived for different phases of the 20-day oscillation of stratospheric ozone at 7 hPa in the Northern Hemisphere. The streamline at Ψ = −2 × 107 m2 s−1 is in the vicinity of the polar vortex edge. The other streamline at Ψ = 4 × 107 m2 s1 surrounds the Aleutian anticyclone and goes to the subtropics. The composites show 20-day period standing oscillations at the polar vortex edge and in the subtropics above Northern Africa, India, and China. The 20-day period standing oscillation above Aral Sea and India is correlated to the strength of the Aleutian anticyclone.

Web searching and Σ2 queries

In the terminology of Logic programming, current search engines answer Sigma1 queries (formulas of the form where is a boolean combination of attributes). Such a query is determined by a particular sequence of keywords input by a user. In order to give more control to users, search engines will have to tackle more expressive queries, namely, Sigma2 queries (formulas of the form ). The purpose of the talk is to examine which directions could be explored in order to move towards more expressive languages, more powerful search engines, and the benefits that users should expect.

Vortex dynamics in the studies of looping in tropical cyclone tracks

This paper proposes criteria for predicting the tendency of looping in tropical cyclone tracks using the approach of vortex dynamics. We model the asymmetric structure of a cyclone by a system of vortex patches. The evolution of such system of vortices is simulated by the method of contour dynamics. A new set of exact analytic formulas for contour dynamics calculations is derived, which is shown to be more computationally effective. Based on point-vortex models, we derive analytic formulas for the criteria of looping in a cyclone track. From numerical experiments, the simulated trajectories obtained from the point-vortex system and vortex patch system agree quite well. Hence, the looping criteria obtained from the point-vortex system can be applied by forecasters to stay alert for tendency of looping in a cyclone track. To demonstrate the applicability of the proposed criteria, the trajectory of Typhoon Yancy (9012), whose field data are available from ''TCM-90'', is simulated. The case study shows that the asymmetric structure similar to the pattern of a beta gyre is responsible for its recurvature when Yancy landed Fujian Province, China on 20 August 1990.

Mães obesas, filhotes obesos: estudo experimental

O aumento da obesidade materna pode refletir em efeitos deletérios na prole adulta, manifestos diferentemente de acordo com o gênero do indivíduo. Este trabalho teve como objetivo verificar a hipótese de que a obesidade materna provoca alterações metabólicas, na estrutura do tecido adiposo e hepático e mudanças de perfil inflamatório nas proles adultas de machos e fêmeas. Fêmeas C57BL/ 6 receberam dieta padrão (SC, 17% da energia proveniente do lipídeo) ou dieta hiperlipídica (HF; 49% da energia proveniente do lipídeo) durante oito semanas pré-gestacionais até a lactação. Após o desmame, os filhotes foram divididos nos grupos: SCM (machos), SCF (fêmeas), HFM (machos) e HFF (fêmeas). As características metabólicas foram avaliadas pela massa corporal (MC), glicemia de jejum, área sob a curva no teste oral de tolerância a glicose; concentrações de triglicerídes (TG) hepáticos e estimativa da esteatose hepática; análise plasmática de insulina, colesterol total (CT), triglicerídes (TG) e adipocinas; distribuição e análise morfológica do tecido adiposo e estado pró-inflamatório dos filhotes. Diferenças entre os grupos foram analisadas pelo Teste T não pareado (dados entre progenitoras e pares de grupos nas proles); one-way ANOVA com pós-teste de Tukey (para proles) e two-way ANOVA (efeito da dieta materna e gênero). O nível de significância adotado foi de P≤0,05. Progenitoras HF tiveram maior MC (+20%), glicemia elevada (+22%) e intolerância à glicose em comparação ao grupo SC. A partir da quarta semana, a MC mostrou-se maior nas proles HF, em ambos os gêneros, quando comparados às proles SC. Na 12 semana, a MC foi 20% maior no grupo HF macho e 30% maior no grupo HF fêmea do que seus controles (p<0,0001, ambos os gêneros). Intolerância à glicose foi observada em machos e fêmeas HF em relação aos seus contrapares SC (+20%, p<0,05). Proles HF demonstraram hepatomegalia com maior acúmulo de TG hepático, resultando em maior percentual de esteatose em machos (27%) e fêmeas HF (25%). Proles HF apresentaram incremento na adiposidade (+20%) e nos níveis de CT e TG do que seus congêneres SC. Níveis plasmáticos de leptina e insulina foram maiores, enquanto houve diminuição da adiponectina no grupo HF macho em relação ao grupo SC macho. Hipertrofia de adipócitos foi observada nas proles HF. TNF-alfa, IL-6 e leptina foram mais expressos em proles HF, porém diminuição na expressão de adiponectina foi evidenciada nas proles geradas por mães obesas. A luz do exposto, a dieta HF administrada em mães antes e durante períodos de gestação e lactação leva à obesidade materna que tem consequências na prole, tais como remodelamento do tecido adiposo, juntamente com alterações bioquímicas e metabólicas dos adipócitos, intensificando o estado pró-inflamatório da prole, em ambos os gêneros, na idade adulta.

PHYLOGENY OF RHESUS-MONKEYS (MACACA-MULATTA) AS REVEALED BY MITOCHONDRIAL-DNA RESTRICTION ENZYME ANALYSIS

Mitochondrial DNA, purified from 36 samples of 23 local populations which are widely distributed in Vietnam, Burma, and 10 provinces of China, has been analyzed to model the phylogeny of rhesus monkeys. The 20 local populations of China may represent nearly all major populations in China. Using 20 restriction endonucleases of 6-bp recognition, we observed a total of 50-61 sites in the various samples. By combining the cleavage patterns for each enzyme, the 36 samples were classified into 23 restriction types, each of which was found exclusively in the respective population from which samples were obtained By combining the earlier study of Indian rhesus monkeys, phylogenetic trees, which have been constructed on the basis of genetic distance, indicate that rhesus monkeys in China, Vietnam, India, and Burma can be divided into seven groups. Integrating morphological and geographical data, we suggest that rhesus monkeys in China, Vietnam, and Burma may be classified into six subspecies-M. m. mulatta, M. m. brevicaudus, M. m. lasiotis, M. m. littoralis, M. m. vestita, and M. m. tcheliensis-and rhesus monkeys in India may be another valid subspecies. M. m. tcheliensis is the most endangered subspecies in China. Divergence among subspecies may have begun 0.9-1.6 Ma. The radiation of rhesus monkeys in China may have spread from the southwest toward the east. The taxonomic status of the Hainan monkey and the Taiwan monkey require further investigation.

Bacterial diversity in activated sludge from a consecutively aerated submerged membrane bioreactor treating domestic wastewater

The bacterial diversity of activated sludge from submerged membrane bioreactor (SMBR) was investigated. A 16S rDNA clone library was generated, and 150 clones were screened using restriction fragment length polymorphism (RFLP). Of the screened clones, almost full-length 16S rDNA sequences of 64 clones were sequenced. Phylogenetic tree was constructed with a database containing clone sequences from this study and bacterial rDNA sequences from NCB1 for identification purposes. The 90.6% of the clones were affiliated with the two phyla Bacteroidetes (50%) and Proteobacteria (40%), and beta-, -gamma-, and delta-Proteobacteria accounted for 7.8%, 28.1%, and 4.7%, respectively. Minor portions were affiliated with the Actinobacteria and Firmicutes (both 3.1%). Only 6 out of 64 16S rDNA sequences exhibited similarities of more than 97% to classified bacterial species, which indicated that a substantial fraction of the clone sequences were derived from unknown taxa. Rarefaction analysis of operational taxonomic units (orrUs) clusters demonstrated that 150 clones screened were still insufficient to describe the whole bacterial diversity. Measurement of water quality parameter demonstrated that performance of the SMBR maintained high level, and the SMBR system remained stable during this study.

Effects of Cd2+ and Pb2+ on the substrate biofilms in the integrated vertical-flow constructed wetland

The effects of single Cd2+ and Pb2+, and combined Cd2+ and Pb2+ on dehydrogenase activity and polysaccharide content of the substrate biofilms in the integrated vertical-flow constructed wetland (IVCW) were studied. Dehydrogenase activities decreased linearly with the increasing concentrations of Cd2+ and Pb2+ at different times (6, 24, 72, and 120 h). The activities at both 6 and 24 h were significantly higher than that at 72 and 120 h in the case of single and combined treatments. The single Cd2+ and Pb2+ treatments significantly inhibited dehydrogenase activities at concentrations in excess of 20 mu mol/L Cd2+ and 80 mu mol/L Pb2+, respectively. The inhibitory effect of Cd2+ was much greater than that of Pb2+. At the same time, the combined treatment of Cd2+ and Pb2+ Significantly inhibited dehydrogenase activities at all five concentrations studied and the lowest combined concentration was 1.25 mu mol/L Cd2+ and 5 mu mol/L Pb2+. A synergistic effect of Cd2+ and Pb2+ was observed. On the other hand, polysaccharide contents varied unpredictably with the increasing concentrations of Cd2+ and Pb2+ and extended experimental time. There were no significant statistical differences within the range of concentration and time studied, whether singly or in combination. These results implied that the effects of heavy metals on biofilms should be a concern for the operation and maintenance of constructed wetlands.

Plankton community composition in the Three Gorges Reservoir Region revealed by PCR-DGGE and its relationships with environmental factors

To explore the relationships between community composition and the environment in a reservoir ecosystem, plankton communities from the Three Gorges Reservoir Region were studied by PCR-denaturing gradient gel electrophoresis fingerprinting. Bacterial and eukaryotic operational taxonomic units (OTUs), generated by DGGE analysis of the PCR-amplified 16S and 18S rRNA genes, were used as surrogates for the dominant "biodiversity units". OTU composition among the sites was heterogeneous; 46.7% of the total bacteria] OTUs (45) and 64.1% of the eukaryotic OTUs (39) were identified in less than half of the sampling sites. Unweighted pair group method with arithmetic averages (UPGMA) clustering of the OTUs suggested that the plankton communities in the Xiangxi Rive sites were not always significantly different from those from the Yangtze River sites, despite clear differences in their environmental characterizations. Canonical correspondence analysis (CCA) was applied to further investigate the relationships between OTU composition and the environmental factors. The first two CCA ordination axes suggested that the bacterial community composition was primarily correlated with the variables of NO3--N, dissolved oxygen (DO), and SiO32--Si, whereas, the eukaryotic community was mainly correlated with the concentrations of DO, PO43--P, and SiO32--Si.

Short-term effects of drawing water for connectivity of rivers and lakes on zooplankton community structure

During 28-29, September 2005, water was drawn from Hanjiang River and Houguan Lake to the Yangzi River via Sanjiao Lake and Nantaizi Lake in Wuhan in order to provide favorable conditions for ecosystem restoration. To evaluate the feasibility and validity of drawing water as a means of ecosystem restoration, zooplankton populations were studied 3 times (before, immediately after finishing and a month after drawing water) at seven locations from 27 Sept. 2005 to 2 Nov. 2005. Water quality in the lakes was mostly improved and zooplankton species richness decreased as soon as drawing water had finished but increased a month after drawing water. Zooplankton density and biomass was reduced in the lakes by drawing water but was increased at the entrance to Sanjiao Lake because of landform geometry change. Before drawing water, most species in Sanjiao Lake e.g., Brachionus sp. and Keratella sp. were tolerant of contamination. After drawing water oligotrophic-prone species such as Lecane ludwigii and Gastropus stylifer emerged. We conclude that drawing water could be important for improving water quality and favour ecosystem restoration. Dilution of nutrient concentrations may be an important role in the effect.
