Repercussões de um curso de formação continuada a distância em matemática na visão dos participantes

Este artigo apresenta os resultados de uma pesquisa que teve por objetivo geral avaliar as repercussões de um curso de formação continuada a distância em matemática na visão dos participantes. Contou com a participação de um grupo de dezoito professores dos anos iniciais do Ensino Fundamental, participantes do referido curso. Para coletar os dados, utilizaram-se questionários, entrevistas semiestruturadas, documentos relacionados ao curso realizado e memoriais construídos pelos docentes ao longo da formação. Para analisar os dados coletados, utilizou-se a Análise Textual Discursiva, de Moraes e Galiazzi (2011), delineada em quatro etapas: organização do corpus, unitarização dos elementos de significado, definição das categorias e produção de metatexto. Da análise resultaram duas categorias, intituladas Qualificação da prática pedagógica e Aprimoramento da formação inicial. Os resultados evidenciaram que o curso de formação continuada contribuiu para qualificar a formação dos professores e a sua prática pedagógica. Neste sentido, destaca-se a importância de promover espaços formativos e socializadores de conhecimento, visando a uma formação que integre e articule diferentes saberes e, ao mesmo tempo, admita as singularidades dos sujeitos no seu processo de formação

Ants Sleep, Plants do not: The Variation in Species’ Activity Influences the Topology of Interaction Networks

The emergence of graph theory allowed using the complex network approach to aggregate detailed information about interactions between species. Although the use of the complex network approach has improved the understanding about community structuring, few aspects such as the temporal variation in the species’ activity pattern in the networks’ topology were explored so far. The current study used the ecological network approach to investigate ants interacting in the extrafloral nectary (EFN) of plants in order to test the hypothesis that the temporal variation in the foraging behavior of these animals affects the networks’ topology. In order to assess the temporal effect on the interaction networks, 24-hour collections divided in two 12-hour shifts (day and night) were performed in 20 plots, thus totaling 288 collection hours over 6 months. The ant-plant interaction networks presented similarity among the topological metrics assessed throughout the day. Different ant species presented distinct foraging times. Thus, two modules referring to the day and night shifts emerged from the network and presented specific species at each foraging shift. On the other hand, the plants kept on providing the resource (active EFNs) throughout the day. The results found in the current study have shown that ecological networks keep their structures constant; however, the ecological processes ruling these networks can better respond to the effects caused, for example, by the temporal variation in species’ activity. Therefore, it is worth always taking into consideration the importance of ecological processes at the time to analyze interactions in the nature

A FUNÇÃO CONTROLE EM UMA INSTITUIÇÃO FEDERAL DE ENSINO SUPERIOR: UM ESTUDO DE CASO DA AUDITORIA INTERNA

O artigo aborda a atuação da Auditoria Interna de uma Instituição Federal de Ensino Superior - IFES na percepção dos seus gestores e auditores em relação às atividades desenvolvidas no apoio à gestão, evidenciando o resgate histórico da implantação da unidade de controle interno na Instituição. A pesquisa, um estudo de caso único, foi realizada por meio de metodologia qualitativa, utilizando para a coleta de dados, documentos da Instituição, questionários e entrevistas. O resultado da pesquisa concluiu que a percepção geral é de que a unidade contribui para a gestão, embora se entenda que há necessidade de aprimorar o relacionamento interno e de apoio à gestão, havendo necessidade de pró-atividade, voltar-se para o controle de resultados, promover cursos sobre as atividades de controle e aperfeiçoar a divulgação de suas atividades a fim de oportunizar uma cultura mais propícia aos controles de modo geral

Nutritional and metabolic parameters of sheep fed extruded roughage

The objective was to evaluate the effect of using different levels of inclusion of extruded roughage to replace corn silage on nutritional and metabolic parameters in sheep. For this, 20 ewes aged over three years were used, housed in metabolic cages, distributed in a completely randomized design in four treatments, which consisted of different levels of inclusion of extruded roughage to replace corn silage (20%, 40%, 60% and 80%). Dry matter intake (DMI) and water intake were calculated by the difference between what was offered and what was left over. Blood glucose and energy and protein metabolites were obtained through blood collection by jugular venipuncture and subsequent laboratory analyses, and feeding behavior by observation every 5 minutes for 24 hours. DMI and water intake increased linearly with the inclusion of extruded roughage in the diet. The greater inclusion of extruded roughage reduced the total chewing time, consequently increasing the efficiency of ingestion, rumination and total chewing. There was no effect of treatments on the concentrations of energy and protein metabolites, with the exception of the urea and uric acid concentration, in which there was a quadratic effect with the use of extruded roughage. The inclusion of extruded roughage in the diet of sheep increases the dry matter intake, without altering the digestibility of nutrients, reducing the time spent on chewing, in addition to maintaining energy and protein metabolism at adequate serum levels.The search for technologies to increase productivity of the herds, without increasing production costs, brings a positive highlight to extruded feeds, since these products act to maximize digestive efficiency.

Manoel Luiz Reefs morphology unveiled by high resolution satellite images (North Brazilian Continental Shelf)

The reefs of Manoel Luiz are located 100 nautical miles N from the city of São Luís, capital of the State of Maranhão - Brazil. The region is practically unconquerable, due to the great concentration of shallow reef pinnacles; it has never been possible to map the area by traditional methods, due to the dangers to navigate. The images acquired in June 2018, by programmed WorldView-3 satellite (30 cm resolution), revealed for the first time the real and exuberant reef formation with innumerable constructions, predominantly individual with circular, or linear and coalescent format. The reefs of Manoel Luiz are not constructed by corals. Drop-camera videos shows that sparse colonies of corals are fixed on hard structures formed (covered) by superimposed crusts of calcareous algae. The location of Manoel Luiz reefs remained almost 300 years unknown to navigators, since the year 1500, attributed to the discovery of Brazil, until 1820, when it was described by the French hydrographer Adm. Baron de Roussin, and another 198 years to be precisely georeferenced and mapped

O presente artigo analisa o direito humano ao meio ambiente à luz de princípios administrativos ambientais aplicados ao ciclo nuclear brasileiro. A notícia da retomada das obras de Angra 3 reacende o debate sobre os riscos da geração de energia nuclear. O processo de geração envolve a extração e enriquecimento de minério de urânio, atividade desenvolvida no município de Caetité/BA. Tais atividades demandam fiscalização efetiva das autoridades públicas. Assim, convém analisar o histórico enfrentado por este município numa luta desigual. Para tanto, utiliza-se de metodologia de revisão bibliográfica, especialmente em estudos e relatórios oficiais relevantes sobre o tema

DESEMPENHO DE FRANGOS DE CORTE CRIADOS EM DIFERENTES TIPOS DE CAMA E TAXA DE LOTAÇÃO

Objetivou-se avaliar os efeitos dos diferentes tipos de cama e densidade populacional no desempenho de frangos de corte. Foram utilizados 264 pintos de um dia de idade de ambos os sexos da linhagem Hubbard. Utilizou-se o delineamento em blocos ao acaso com seis tratamentos e quatro repetições num arranjo fatorial 3 x 2 x 2 (3 camas: casca de arroz, bagaço de cana e maravalha de madeira; 2 densidades: 10 e 12 aves/m2 e 2 períodos: 1o = 1 a 28 dias e 2o = 29 a 42 dias). As variáveis estudadas foram: consumo de ração, ganho de peso e conversão alimentar das aves. Não se observaram efeitos significativos (P>0,05) dos três tipos de camas nas variáveis estudadas. Houve efeito significativo (P0,05) das duas densidades para ganho de peso, porém ocorreu efeito significativo para consumo de ração (

Species Richness and Diversity in Bee Assemblages in a Fragment of Savanna (Cerrado) at Northeastern Brazil

The conservation of the fauna of bees inhabiting the Brazilian savanna is threatened due to changes in land use in the last decades. We investigated the composition, species richness and abundance of a bee assemblage in the vicinity of the Chapada Diamantina National Park. In addition, we compiled data on composition and diversity from another bee assemblage located in the same portion of the Cerrado, which was previously investigated by one of us almost 30 years ago, in order to produce a more complete panorama on beta diversity of bees in this region. We used a non-metric multidimensional scaling ordination analysis (NMDS) to compare composition of bee assemblages from diff erent types of open vegetation. We recorded 77 bee species (H’ = 2.95; J = 0.68), 42% of them were singletons. We collected slightly more than half of the species and 60% of the genera recorded in the bee assemblage studied three decades ago. H’ was signifi cantly lower in our area than in the previous study (t = 8.588, p <0.001), but equitability (J) was very similar. Several factors may contribute to these diff erences, including local diff erences in bee assemblage composition, diff erences in the probability of capturing the diff erent species (many rare species), factors affecting the sampling itself, and perhaps species loss over the three decades separating the two studies. The magnitude of species loss is difficult to assess because the two studies were not carried out exactly in the same area and there were differences in sampling time and sampling effort

PROPOSITION FOR THE ALIGNMENT OF THE INTEGRATED MANAGEMENT SYSTEM (QUALITY, ENVIRONMENTAL AND SAFETY) WITH THE BUSINESS STRATEGY

With the current globalized and increasingly competitive organizational scenario, organizations increasingly need strategies to survive in the midst of excessive competition. In order to optimize efforts and resources, the companies, especially industrial companies, started to develop their own Integrated Management System (IMS), namely, quality management system, environmental management system and safety management system, among others, as a plausible and efficient alternative in this sense. However, few companies are aware of the difficulties in aligning their IMS as a strategy. This paper is classified as qualitative, and has used the bibliographic research method for its execution. Therefore, the aim of this paper is formulate the propositions that assist the IMS alignment as a business strategy. The results of this paper allow identify that really exists an interaction in both senses, i.e., the IMS influences a strategy and the strategy influences the IMS. The main contribution of this article is to support in the development based on the articulation of the IMS-related theory and business strategy

Prêmio por informação: uma investigação empírica da microestrutura do mercado acionário no Brasil

Este artigo estima a probabilidade de informação privilegiada (PIN), para ações do Índice Brasil durante o período de 2006 até 2011. O PIN é uma proxy para informação privada e é incorporado ao método de Fama French (1993) para separar os portfolios e explicar seus retornos. A combinação do PIN com as variáveis valor de mercado e índice book-to-market possibilita, para alguns portfolios, aumento do retorno e diminuição do risco. A significância das variáveis na explicação dos retornos é testada utilizando modelos de Markov-switching. Os resultados demonstram que o PIN é um fator importante na explicação dos retornos dos portfolios.This article makes use of tick-by-tick data to estimate the probability of informed trading (PIN) to IBRX stocks. We add PIN in Fama French (1993) method to separate portfolios and explain their returns. Our evidence points out we may find some portfolios, which have statistically higher return and lower risk in a Markov-switching regression. The results demonstrate PIN is an important factor in explaining portfolio returns
