Arranjos institucionais entre o poder público municipal e instituições privadas para oferta de vagas na educação infantil

This paper features a research of the partnerships/agreements between the municipal public services and the private sphere to the offer of vacancies in Early Education, in the large counties of São Paulo. The study allowed us to identify different arrangements between the municipal public service and private institutions, which 30 of the 54 large counties of São Paulo turn to the services from partnerships as a mean to attend the local demand, including the institutions with lucrative purposes, being different of the traditional forms of partnerships instituted in Early Education. The text is based on the literature analysis about the theme and the information collected during the research from phone calls to municipal administrators, municipal official sites and government sites.

Currículos de formação de professores de língua portuguesa: instituições autônomas e o poder de sua história

Baseia-se em uma pesquisa interinstitucional que focaliza o âmbito mais amplo em que são formuladas e implementadas as políticas de formação de professores no Estado de São Paulo. Tem por objetivo contribuir para a elucidação das forças presentes em movimentos de reforma curricular nos cursos de licenciatura, cotejando dados e aspectos socioculturais e institucionais circundantes. A análise incide sobre projetos pedagógicos de dois cursos de Letras de duas universidades públicas paulistas. Essas instituições desenvolveram, nos últimos anos, projetos ou ações de formação de professores para a escola básica, e é nesse contexto que se inserem os projetos pedagógicos analisados, que são tomados como exemplos de caminhos diferenciados que as universidades traçam, influenciadas pela história de cada instituição. O procedimento de pesquisa adotado foi a análise documental e o conceito de currículo em processo orientou as reflexões desenvolvidas. Reafirma-se, como em outros estudos, que a necessária integração entre saberes pedagógicos e saberes provenientes da área de referência continua sendo tarefa difícil, que as circunstâncias na criação dos cursos e a formação superposta deixou suas marcas nas instituições e que as tentativas para superá-la constituem exemplos esparsos e não modelos generalizados, o que ressalta a relevância da continuidade das pesquisas sobre o currículo dos cursos de licenciatura.

Emissão luminescente no titanato de cálcio dopado com íons de terras-raras

Through the polymeric precursor method were synthesized samples Ca0.98Sr0.01X0.01TiO3 (X= Eu3+, Sm3+ and Pr3+), which under different heat treatments were obtained with levels of distinct structural order-disorder. The synthesized materials were characterized by X-ray diffraction, confirming the obtaining of ahomogeneous material with perovskite-type orthorhombic structure. This characterization allowed evaluating the average crystallite size of the samples that varies depending on the rare-earth ion. The results of photoluminescence emission confirmed the presence of this optical phenomenon at room temperature and its relationship to the level of order-disorder structural system. The photoluminescence emission is more intense in samples annealed at 500 ° C (independent on the dopant ion), the variation of the dopant influence on the emission intensity due to charge transfer between the host and emitting rare-earth ion, where the doped with Pr3+ ion has charge transfer more efficient and hence more intense emission in the photoluminescence. Another factor that favors the optical property of the samples is the charge compensation, as it contributes to the increase in structural disorder due to formation of Ca2+ vacancies.

Produtividade de arroz de terras altas em função de reguladores de crescimento

The use of sprinkler-irrigation and/or high levels of fertilization in upland rice can increase plant height and hence plant lodging. Lodging can be controlled by using growth regulators, in order to reduce plant height. The objective of this study was to evaluate the efficiency of plant growth regulators applied at the stage of panicle primordium differentiation on the reduction of plant height and the impact on grain yield and its components of upland rice cultivar Primavera, under sprinkler irrigation. The experiment was arranged in a 3x4 factorial randomized blocks design with four replications. Treatments consisted of: mepiquat chloride and trinexapac-ethil applied at doses 9, 50, 100, and 200 mg a.i. ha-1, and paclobutrazol at doses of 0, 25, 50, and 100 mg a.i. ha-1. Plant growth regulators reduced rice plant height; increasing doses of regulators reduced upland rice grain yield and its components; trinexapac-ethyl was the most harmful to rice grain yield.In this study, it was not identified the dose of growth regulator that allied reduction in plant height and did not cause decrease in rice yield.

Desenvolvimento radicular e aéreo, nutrição e eficiência de absorção de macronutrientes e zinco por cultivares de arroz de terras altas afetadas pela adubação fosfatada

In Brazil, phosphorus availability is one factor that that more limit yield of upland rice under rainfed system. Then, better understanding of cultivars development at phosphorus soil fertilization is very important in the production systems making this more sustainable. The objective was to evaluate the influence of phosphorus doses applied to the soil over the root length, root and shoot dry matter, concentration and content of macronutrient and zinc in shoot and root as well as the efficiency of nutrient uptake per meter root of upland cultivars of intermediate and modern groups. The experiment was carried out in greenhouse conditions in a completely randomized design in factorial scheme 4 x 4. Treatments were four levels of P fertilization applied at the soil (0, 50, 100 and 200 mg dm(-3) of P) and four upland rice cultivars (Maravilha - modern group, IAC-201, IAC-202 and Carajas - intermediate group). There is increase in phosphorus availability in the soil with increasing levels of P fertilization. Under low phosphorus availability, cultivars of the intermediate group have better shoots and root system development in relation to the modern cultivar group. Level of phosphorus affected nutrients contents in shoots and root system of upland rice cultivars. The increasing phosphorus fertilization increased uptake of nutrients per meter of root; and although under higher phosphorus availability there was a greater root growth, in low phosphorus availability root growth was greater at the expense of shoot growth.

Acidez do solo afetando concentração de micronutrientes, atividade da enzima nitrato redutase e produtividade em plantas de arroz de terras altas

The lowest grain yield of rice under no-tillage system (NTS) in relation to the conventional system may be due to the predominance nitrate in the soil and the low nitrate reductase activity. Another reason may be caused by micronutrient deficiency because of superficially soil acidity corrections. Therefore, the objective of this study was to evaluate the changes caused by soil pH in the N forms in the soil, micronutrients concentration in rice plants, nitrate reductase activity, yield of rice and its components. The experiment was performed in a greenhouse conditions. The experimental design was a completely randomized in a factorial three (levels of soil acidity) x five (micronutrients sources) with four replications. The addition of micronutrients does not affect levels of nitrate and ammonium in the soil; soil acidity significantly affects levels of nitrate and ammonium in the soil, concentration of micronutrients in rice plants and crop yield and its components; medium soil acidity (pH 5.5) result in medium to high levels of Cu and Fe, medium level of Zn and Mn, high nitrate reductase activity, resulting in higher dry matter, tillers, panicles, spikelets, weight of 100 grains and hence grain yield.

Acúmulo de silício na parte aérea de cultivares de arroz de terras altas afetado pela aplicação de silicato e carbonato no solo

Even the element silicon being the most uptake by rice plant, many benefit effect like: increase of pest and disease tolerance, decrease of lost of water by transpiration and better the leaf architecture becoming the leafs more erect, resulting as well at the better photosynthesis efficacy. There is not too much knowledge about the uptake march in upland rice plants. This study aimed to evaluate the content of silicon in two upland rice cultivars by the influence of the application of silicate and limestone at the soil. The experiment was carried in Hapludox soil in a completely randomized experimental design in 2x2x7 factorial scheme in four replications. The treatments were consisted of calcium silicate fertilizer and limestone in interaction with seven period of physiological stage, using the upland rice cultivars Caiapo and Maravilha. At the cultivar Maravilha Si accumulation begin from tillering and achieve it better value at the microsporogenesis, while the Caiapo cultivar, occurs between tillering until the mily grain. Caiapo shows efficient Si accumulation when it was supplied to the soil. Plant organs that more accumulated silicon in both upland rice cultivars followed decreased order: stem > leaf > panicle.
