Accuracy in dictation after improvement of reading and copying skills in a student with learning difficulties

The aim of this study was to use systematic teaching in a clinical setting using software to teach reading and writing in one boy with learning difficulties and obtain accurate performance in dictation. In the pre-test, the student showed good performance in matching-to-sample tasks (96% in matching printed words to dictated words; 88% in matching pictures to dictated words), although he obtained a low percentage of correct answers in the dictation of constructed responses (52%) and manuscripts (24%). The teaching strengthened the selection of printed words matched to dictated words and copying words. The student obtained 100% correct answers in the teaching tasks. In post-tests of dictation, he obtained 100% correct answers in constructed response and 96% correct answers in manuscripts. The results indicate that carefully teaching copying may promote accuracy in the performance of responding to minimal units in dictation tasks.

The Buffalo Genome and the Application of Genomics in Animal Management and Improvement

The publication of the human genome sequence in 2001 was a major step forward in knowledge necessary to understand the variations between individuals. For farmed species, genomic sequence information will facilitate the selection of animals optimised to live, and be productive, in particular environments. The availability of cattle genome sequence has allowed the breeding industry to take the first steps towards predicting phenotypes from genotypes by estimating a genomic breeding value (gEBV) for bulls using genome-wide DNA markers. The sequencing of the buffalo genome and creation of a panel of DNA markers has created the opportunity to apply molecular selection approaches for this species.The genomes of several buffalo of different breeds were sequenced and aligned with the bovine genome, which facilitated the identification of millions of sequence variants in the buffalo genomes. Based on frequencies of variants within and among buffalo breeds, and their distribution across the genome compared with the bovine genome, 90,000 putative single nucleotide polymorphisms (SNP) were selected to create an Axiom (R) Buffalo Genotyping Array 90K. This SNP Chip was tested in buffalo populations from Italy and Brazil and found to have at least 75% high quality and polymorphic markers in these populations. The 90K SNP chip was then used to investigate the structure of buffalo populations, and to localise the variations having a major effect on milk production.

Seleção recorrente em abobrinha 'piramoita' (Cucurbita moschata Duch.)

Seleção recorrente é um dos métodos mais eficientes para o melhoramento de espécies alógamas, especialmente quando progênies S1 são utilizadas. Considerando-se que abobrinha geralmente não apresenta perda de vigor pela endogamia, este método pode ser adequado para o melhoramento desta espécie. Neste trabalho foram realizados experimentos com o objetivo de avaliar a eficiência da seleção recorrente em abobrinha 'Piramoita'. Foram realizados três ciclos de seleção recorrente a partir da cultivar Piramoita (população P0), com avaliação e seleção de progênies S1. Novas populações foram obtidas com a recombinação de plantas das progênies selecionadas, utilizando-se sementes remanescentes. No primeiro ciclo foram avaliadas 74 progênies e selecionadas 14, no segundo foram avaliadas 60 e selecionadas 10 progênies e no terceiro ciclo foram avaliadas 77 e selecionadas 12 progênies. Foram obtidas populações melhoradas após um (PI), dois (PII) e três (PIII) ciclos de seleção recorrente. Quatro populações (P0, PI, PII e PIII) foram avaliadas em um delineamento em blocos ao acaso, com oito repetições e cinco plantas por parcela. Em todos os experimentos foram avaliadas as seguintes características: número de frutos total e comercial por planta, % de frutos comerciais, produção, em massa, de frutos total e comercial por planta e a massa média de fruto comercial. Foram observados aumentos de produção lineares significativos ao longo dos ciclos de seleção. Para número de frutos total e comercial e produção, em massa, total e comercial foram obtidos aumentos com a população PIII, comparativamente a população inicial, de 32, 63, 24 e 57%, respectivamente. A massa média de fruto comercial não foi afetada pela seleção recorrente. Conclui-se que a seleção recorrente foi eficiente para melhorar a abobrinha 'Piramoita'...

ASIAN SOYBEAN RUST INTEGRATED MANAGEMENT POTENTIAL: DISEASE SEVERITY, PLANT DEVELOPMENT AND YIELD COMPONENTS, CULTIVAR MG/BR-46 (CONQUISTA)

Soybean rust caused by Phakopsora pachyrhizi Sydow & P. Sydow is one of the major diseases of the soybean crop. The aim of this study was to evaluate the effects of sowing dates, plant populations and reduced doses of fungicides on soybean rust severity and its effects on plant development and yield, cultivar MG/BR46 (Conquista). Field experiments were conducted in the 2009/2010 and 2010/2011 harvests, under natural rust infestation of soybean rust. As from the appearance of the first disease symptoms, also began the fungicide spraying and the disease severity assessments. To understand the nature and extent of the effects of different treatments, a multivariate analysis of factors was applied. For the majority of the agronomic characters and factors, one-third to two-thirds of their variability can be explained by changes in plant populations or by differences in the fungicide treatments, and the remainder, was explained by sowing date variations. The fungicide treatments and sowing dates are determinants in disease severity and its interference on crop productivity. The characters of plant growth are more dependent on plant population variations. Treatments with azoxystrobina + ciproconazol promoted smaller disease severities, reflecting in productivity increase. The plant populations can be reduced up to 160.000 plants ha(-1) without losses in the disease control and the soybean yield. In general, the earliest sowings provided increase in the plant development, although the rust control was less efficient.
