Uma descrição semiótica da metáfora no ensino de biologia: asserções sobre a célula animal

The main objective of this survey is describing signly the metaphor learning resource, with focus on biology education. Our teorical reference is the peircean semiotics, because it means solid heritage to code surveys implicated at science education, it led us to do an explanation about the main lines about that reference, addressed to researchers and lecturers interested in those reasonings. In the description yearned, another objectives appear: demonstrate diferences between metaphor/analogy and pragmatic analogy; to list metaphors, from cell representation analysis, and argue about principals diferences and probable cognitive consequences between the metaphor event in the visual representation and speech sentences. Therefore we analysed the animal cell of a high school first grade studying book – biology – cell biology – used by São Paulo and another state students. The findings demonstrate the undeniable importance of the metaphor as a learning tool in the biology education, and new findings about that, such as its limits in the concept elaboration, gnosiologic consequences for receptioning, the search needs for propositions– pictures between concept relations – in the science speech construction, and other results.

Cognição Numérica de crianças pré-escolares brasileiras pela ZAREKI-K

The Numerical Cognition is infl uenced by biological, cognitive, educational and cultural factors. It consists of a primary system, called Number Sense that would be innate and universal, also of secondary systems: the Calculation, implied to perform mathematical operations by means of symbols or words and Number Processing, which is divided into two components, Number Comprehension, related with the understanding of numerical symbols and Number Production, which includes reading, writing and coun-ting numbers. However, studies that show the development of these functions in children of preschool age are scarce. Therefore, aims of this study were to investigate numerical cognition in preschool Brazilian children to demonstrate the construct validity of the ZAREKI-K (A Neuropsychological Battery for the Assessment of Treatment of Numbers and Calculation for preschool children). The participants were 42 children of both genders, who attended public elementary schools; the children were evaluated by this battery and WISC-III. The results indicated signifi cant differences associated with age which children of 6 years had better scores on subtests related to Number Production, Calculation and Number Comprehension, as well moderate and high correlations between some subtests of both instruments, demonstrating the construct validity of the battery. In conclusion, preliminary normative data were obtained for ZAREKI-K. The analyses suggested that it is a promising tool for the assessment of numerical cognition in preschool children.Keywords: Mathematics, number, preschoolers, working memory, Developmental Dyscalculia.

Drivers of change in animal protein production systems: changes from 'traditional' to 'modern' beef cattle production systems in Brazil

Until 1990, beef cattle production in Brazil was recognized as an enterprise of low investment, low cost of production, as well as an extensive production system that used large land areas to be economically feasible. The situation changed for the Brazilian beef market when the economy stabilized in 1994 and all sectors involved in the beef supply chain were able to predict their associated costs and profits. During the same period, purchasing power of the Brazilian population grew, and as a consequence, consumers began to demand higher quality beef products. This new scenario in the late 1990s and early 2000s has led to more intensive beef production systems in Brazil as well as the need for a greater understanding of how technologies might be applied. As consequence of this evolution, in the last five years, a necessity to increase beef production has occurred. The quality of Brazilian beef has improved compared with beef produced 15 years ago, but continued improvements are needed to achieve excellence in terms of large-scale production of high quality beef, be sustainable over a long period of time, and increase our contribution to global food security.

Construção de um indicador qualitativo (status de saúde) para avaliação da qualidade de saúde animal de propriedades rurais

Aiming at developing a tool for assessing the magnitude of farm animal health, an indicator named herd “animal health status” was built. To illustrate the construction of the indicator, serum samples were taken from 923 goats on 17 goat farms in the state of Sao Paulo, Brazil, where three diseases were evaluated along with their impact percentages: caprine arthritis encephalitis, toxoplasmosis and neosporose – all of an infectious and transmissible nature and the cause of considerable economic losses. The mathematical rationale underlying the building of the “animal health status” indicator ranks properties on a 0 - 100% scale in terms of disease positivity in the herd, with the lowest indicator value indicating the highest cumulative disease frequency (0% = all animals tested positive for the three diseases, 100% = all animals tested negative for all diseases). Anti-T. gondii, anti-N. caninum and anti-CAEV antibodies were tested using indirect immunofluorescence reaction (IIFR ≥ 16), Neospora agglutination test (NAT ≥ 25) and agarose gel immunodiffusion (AGID positive or negative), respectively. The animal health status of the farms ranged from 32.38% to 96.40% according to disease positivity. The animal health status value will have a direct reflection on the production chain both on and off the farm, providing not only great market advantages, due to how the expression of animal health will add value to livestock farms, as well as on the consumer who can check the quality of animal health at the beginning of the production chain.

Resíduos de antibióticos e antiparasitários em alimentos de origem animal

O Brasil é considerado um grande produtor e consumidor de carnes, leite e alimentos de origem animal e os medicamentos veterinários têm sido amplamente utilizados na criação dos animais destinados ao consumo humano, com o intuito de prevenir o aparecimento de doenças e também como promotores de crescimento. Os fármacos utilizados para esta finalidade, no entanto, podem ocorrer nos alimentos derivados desses animais tratados, com conseqüências sobre a saúde humana. Além das substâncias utilizadas intencionalmente, a contaminação ambiental ou a presença de contaminantes em rações constitui uma fonte potencial de compostos cuja concentração no alimento final processado pode exceder os limites de segurança estabelecidos para garantir a saúde humana. Com o intuito de promover maior segurança alimentar, no Brasil, foram estabelecidos os programas PNCRC e o PAMVet, que são responsáveis pelo monitoramento da presença de substâncias ilegais (como os antimicrobianos nitrofuranos) e também, visam o controle do Limite Máximo de Resíduos (LMR). O objetivo do presente trabalho é reunir e discutir as informações sobre os principais resíduos e contaminantes de medicamentos veterinários em alimentos de origem animal no Brasil, assim como as publicações referentes às avaliações mais recentes desses produtos alimentícios presentes no mercado brasileiro. Estas informações serão utilizadas para novas discussões relacionadas ao uso adequado de medicamentos veterinários e à proposição de estudos de farmacocinética que poderão fundamentar o estabelecimento do período de carência para esses produtos farmacêuticos.

Adaptação do comportamento animal e mundos emergentes

Discutimos as implicações da noção de adaptação que é uma noção chave para a teoria da evolução clássica. Em lugar de obstinar-se em considerar os organismos como coleção de traços adaptados, propomos buscar estudar a evolução por meio de um quadro teórico onde prevalece uma outra ontologia que destaca o fato de que os organismos e as circunstâncias são totalmente integrados. A etapa preliminar necessária para esta reconsideração consiste em passar de uma lógica prescritiva para uma lógica proscritiva. Isto é, da idéia de que tudo que não é permitido, é proibido; à idéia que o que não é proibido, é permitido. Propomos que a idéia de que os sistemas vivos especificam o mundo no qual eles vivem pode modificar nossa maneira de encarar os processos adaptativos.

Animal-side serologic assay for rapid detection of Mycobacterium Bovis infection in multiple species of free-ranging wildlife

Numerous species of mammals are susceptible to Mycobacterium bovis, the causative agent of bovine tuberculosis (TB). Several wildlife hosts have emerged as reservoirs of M. bovis infection for domestic livestock in different countries. In the present study, blood samples were collected from Eurasian badgers (n = 1532), white-tailed deer (n = 463), brushtail possums (n = 129), and wild boar (n = 177) for evaluation of antibody responses to M. bovis infection by a lateral-flow rapid test (RT) and multiantigen print immunoassay (MAPIA). Magnitude of the antibody responses and antigen recognition patterns varied among the animals as determined by MAPIA; however, MPB83 was the most commonly recognized antigen for each host studied. Other seroreactive antigens included ESAT-6, CFP10, and MPB70. The agreement of the RT with culture results varied from 74% for possums to 81% for badgers to 90% for wild boar to 97% for white-tailed deer. Small numbers of wild boar and deer exposed to M. avium infection or paratuberculosis, respectively, did not cross-react in the RT, supporting the high specificity of the assay. In deer, whole blood samples reacted similarly to corresponding serum specimens (97% concordance), demonstrating the potential for field application. As previously demonstrated for badgers and deer, antibody responses to M. bovis infection in wild boar were positively associated with advanced disease. Together, these findings suggest that a rapid TB assay such as the RT may provide a useful screening tool for certain wildlife species that may be implicated in the maintenance and transmission of M. bovis infection to domestic livestock.

An animal movement model incorporating home range and habitat selection

Wildlife biologists are often interested in how an animal uses space and the habitat resources within that space. We propose a single model that estimates an animal’s home range and habitat selection parameters within that range while accounting for the inherent autocorrelation in frequently sampled telemetry data. The model is applied to brown bear telemetry data in southeast Alaska.
