Projects and programs of physical activity for old in the public Brazilian universities: a general view
Get PDFThe objective of this work was to describe a structure of projects/programs existing today in Brazilian public universities, to identify similarities and divergences and to point out indicators for changing new applications. Qualitative research of the descriptive exploratory type. Data were collected using an online instrument with 54 program coordinators, analyzed using the content analysis technique proposed by Bardin. Results: Found similarities regarding teaching strategies for elderly people according to what scientific literature prescribes. There was disagreement regarding the offer of activities in the different programs surveyed; there is no activity model to be followed. There was disagreement as to the type of physical activity offered in the programs. Not all regions have well-structured programs, there is a lack of resources, materials and personnel with experience in the area of physical activity for the elderly; built structures and places for carrying out activities are lacking. The offer of physical activities for the elderly in public universities is not yet a reality in all of them. Most programs increase through university extension and have been one of the maintainers of their legacy. We understand that there are indicators for the formulation of new proposals, such as: the experience of professionals in the field of Physical Education in offering and structuring the physical exercise offered; the need for teacher and continuing training; research and extension together in teaching; the importance of the evaluation as a subsidy for the continuity and prescription of the proposed exercises
Genomic prediction of ordinal traits via application of the BLASSO and BayesCπ methods in simulated data
Get PDFThis paper aims at evaluating the use of BLASSO and BayesCπ methods for the genomic prediction of ordinal traits, studying factors that influence the performance of the models, and if there is a difference in the ranking of individuals. Genotypic and phenotypic information from a simulated population of 4,100 animals, genotyped by 10k markers (QTL-MAS Workshop) were used. 3,000 animals were used for estimation of the predictive ability and bias accessed through 5-fold cross-validation with five repetitions. The other animals were used as a population of selection. One ANOVA and the Ryan-Einot-Gabriel-Welch test were performed to verify, respectively, which factors influence significantly the genomic prediction and if there is a statistical difference between the models. The results show that the four main factors significantly (p < 0.05) affect the predictive ability of GEBVs (genomic estimated breeding values), and that heritability and the number of categories are the most influential factors. Only for ordinal trait 2, with a density of 9k, significant differences (p < 0.05) were observed between the predictive ability of the methods. In general, the BayesCπ method proved to be more efficient in the identification of relevant SNPs and in the ranking of individuals. Finally, there is a slight superiority of the BayesCπ method for the genomic prediction of ordinal traits

Documental analysis of educational public policy: foundations of Paul de Bruyne's quadripolar approach
Get PDFThe present study seeks to explain the techniques and procedures, the concepts and categories with which the interpretation of the object studied, that is - documents related to the High School Technical Professional Education Policy - implemented in Bahia / Brazil, specifically, the reference regarding Paul de Bryne’s quadripolar approach (1977), which provide the theoretical-methodological density of the object studied in relation to the epistemological, theoretical, technical and morphological poles. In this perspective, it is agreed with Gamboa (1987), in the sense that, the accomplishment of a research is not the fulfilment of ‘methodological ritualism’ with a ‘theoretical fad’ in order not to repeat what commonly happens in research in education, in progressively more intense way, of eclectic attempts that randomly collect techniques, methods and theoretical references without a clear understanding of the epistemological foundations and the philosophical implications of the different paths of knowledge
AVALIAÇÃO PARTICIPATIVA E CONDIÇÕES AGROCLIMÁTICAS NO CULTIVO DO FEIJOEIRO EM SISTEMA ORGÂNICO
No full textThe present study aimed at the participatory evaluation of local and improved bean genotypes associated with agroclimatic conditions in organic farming systems. Joint work between the formal and informal sectors, generally represented by rural communities, can contribute to the use and conservation of germplasm adapted to the agroecosystems of agricultural communities. Furthermore, participatory improvement is undoubtedly an excellent strategy for the sustainable development of family farmer communities. Farmers happen to be co-responsible for the research ceasing to be a passive element within the process. The experiments were conducted under field conditions, under organic cultivation, in the agricultural community of Fortaleza, located in Muqui-ES. A total of 39 genotypes were used between cultivars grown in the region and local genotypes in the years 2006, 2007, and 2008. The experimental design was a randomized block design with four replications. It was verified that years of 2006, 2007, and 2008 there were few differences between the genotypes in the characteristics evaluated, except for grain production. The low rainfall in the year 2006 and the high temperatures in the year of 2008 influenced the low production of grains of the genotypes.O presente estudo teve como objetivo a avaliação participativa de genótipos locais e melhorados de feijoeiro associados às condições agroclimáticas em sistema de cultivo orgânico. O trabalho conjunto entre o setor formal e o setor informal, geralmente representado pelas comunidades rurais, pode contribuir no uso e conservação de germoplasma adaptado aos agroecossistemas das comunidades agrícolas e, além disso, o melhoramento participativo é sem dúvida uma excelente estratégia para o desenvolvimento sustentável de comunidades de agricultores familiares, pois o agricultor passa a ser corresponsável pela pesquisa deixando de ser um elemento passivo dentro do processo. Os experimentos foram conduzidos em condições de campo, sob cultivo orgânico, na comunidade agrícola de Fortaleza, situada no município de Muqui-ES. Foram utilizados 39 genótipos entre cultivares melhorados que são cultivados na região e genótipos locais, nos anos de 2006, 2007 e 2008. O delineamento experimental utilizado foi o de blocos ao acaso, com quatro repetições. Foi verificado que nos anos de 2006, 2007 e 2008 houve poucas diferenças entre os genótipos nas características avaliadas, exceto para a produção de grãos. A baixa precipitação no ano de 2006 e as altas temperaturas no ano de 2008 influenciaram a baixa produção de grãos dos genótipos

Low strain integrity tests in piles – 1-D and 3-D numerical modeling and comparisons with results obtained in the field
Get PDFThe risks associated with integrity problems in piles led to the inclusion of this matter in international standards. One of the tests available to evaluate piles integrity is known as low strain integrity test. Low costs, simple and fast execution and no waste generation are some of the main advantages of this test. However, between others, soil and reinforcement of the pile may affect the results and cause some difficulty to interpret them. In this paper two numerical models based on Finite Elements Method are presented: 1-D and 3-D. The results obtained in the numerical simulations of the tests are compared with those obtained in the field with focus in two main aspects: the signals attenuation effects and the reflections in the transition between the reinforced part of the pile and the part in simple concrete
