Why we need signed poetry in bilingual education

A truly bilingual and bicultural education for deaf children requires them to learn about the deaf art-form of sign language poetry. In this article I outline the advantages and challenges of doing this. Reviewing the scarce literature on teaching deaf children signed poetry, whether translated or original, I relate it to the use of literature in L2-learning settings. Reflections of deaf teacher-poets from the UK show that deaf children readily relate to signed poetry, and with informed language focus from teachers it helps them to develop a range of language skills, and express their emotions. Barriers to this, however, include lack of training and awareness for both deaf and hearing teachers - even when the teachers are poets

Por que precisamos de poesia sinalizada em educação bilíngue

Uma verdadeira educação bilíngue e bicultural para crianças surdas requer que elas aprendam a forma de arte surda de poesia em língua de sinais. Neste artigo apresento as vantagens e desvantagens de se fazer isto. Revisando a escassa literatura sobre o ensino de poesia sinalizada para crianças surdas, seja traduzida ou original, eu a relaciono ao uso de literatura em cenários de aprendizagem de L2. Reflexões de professores-poetas surdos do Reino Unido mostram que a criança surda prontamente se simpatiza com a poesia sinalizada, e com o foco linguístico adequado dos professores, isto as ajuda a desenvolver uma gama de habilidades linguísticas e a expressar suas emoções. Barreiras para isto, contudo, incluem a falta de treinamento e apreensão de professores surdos e ouvintes - mesmo quando os professores são poetas

Genome scan revealed new pathways related to meat tenderness in Nelore beef cattle.

A genome wide-association study (GWAS) for Warner-Bratzler shear force (WBSF) measured at different times of meat aging was conducted using genotype data from the Illumina BovineHD BeadChip to identify QTLs in Nelore cattle (n=442).ISAFG 2013. AB.08

Genomic structure and marker-derived gene networks for growth and meat quality traits of Brazilian Nelore beef cattle

Abstract\ud \ud Background\ud Nelore is the major beef cattle breed in Brazil with more than 130 million heads. Genome-wide association studies (GWAS) are often used to associate markers and genomic regions to growth and meat quality traits that can be used to assist selection programs. An alternative methodology to traditional GWAS that involves the construction of gene network interactions, derived from results of several GWAS is the AWM (Association Weight Matrices)/PCIT (Partial Correlation and Information Theory). With the aim of evaluating the genetic architecture of Brazilian Nelore cattle, we used high-density SNP genotyping data (~770,000 SNP) from 780 Nelore animals comprising 34 half-sibling families derived from highly disseminated and unrelated sires from across Brazil. The AWM/PCIT methodology was employed to evaluate the genes that participate in a series of eight phenotypes related to growth and meat quality obtained from this Nelore sample.\ud \ud \ud Results\ud Our results indicate a lack of structuring between the individuals studied since principal component analyses were not able to differentiate families by its sires or by its ancestral lineages. The application of the AWM/PCIT methodology revealed a trio of transcription factors (comprising VDR, LHX9 and ZEB1) which in combination connected 66 genes through 359 edges and whose biological functions were inspected, some revealing to participate in biological growth processes in literature searches.\ud \ud \ud Conclusions\ud The diversity of the Nelore sample studied is not high enough to differentiate among families neither by sires nor by using the available ancestral lineage information. The gene networks constructed from the AWM/PCIT methodology were a useful alternative in characterizing genes and gene networks that were allegedly influential in growth and meat quality traits in Nelore cattle.This study was conducted with funding from EMBRAPA (Macroprograma1,\ud 01/2005) and FAPESP (process number 2012/23638-8).

O comércio internacional de peles silvestres na Amazônia brasileira no século XX

Durante o século XX, o comércio internacional de peles foi responsável pelo abate de milhões de mamíferos e répteis na Amazônia. Negociadas no regime de comércio fluvial e aviamento, as peles seguiam dos portos e seringais, localizados no interior, para as casas aviadoras e exportadoras de Manaus e Belém, de onde eram exportadas principalmente para os Estados Unidos, a Europa e o sul brasileiro. Neste artigo, analisamos documentos fiscais inéditos liberados pelo extinto império econômico do aviamento - a empresa J. G. Araujo -, bem como periódicos da Associação Comercial do Amazonas e os registros portuários da Manáos Harbour Ltd. O comércio internacional de peles silvestres intensificou-se imediatamente após a crise da borracha (1912) e atingiu seu auge entre 1935 e 1946, com o pico durante a Segunda Guerra Mundial. O segundo pico ocorreu na década de 1960, principal e ironicamente logo após a publicação da Lei de Proteção à Fauna (1967). Ao longo do período que antecedeu a aprovação da Convenção sobre o Comércio Internacional de Espécies Ameaçadas (CITES), em 1973-1975, não houve depreciação significativa no preço ou na demanda internacional por peles silvestres, sugerindo um esforço de caça constante e intenso por quase meio século
