Sobre o financiamento no Plano de Desenvolvimento da Educação

Este artigo apresenta uma análise inicial do financiamento das ações do Plano de Desenvolvimento da Educação - PDE -, lançado em abril de 2007 pelo governo federal, focalizando algumas expectativas, impasses e impactos. Muitas das inquietações e dúvidas aqui expostas foram manifestadas no Seminário Itinerante O Plano de Desenvolvimento da Educação - PDE - em Debate nas Universidades Públicas Paulistas, em que especialistas de diferentes instituições tiveram a oportunidade de debater com os formuladores e responsáveis pela implementação do plano. Optou-se por organizar análise em três partes. Na primeira parte, discutem-se alguns pressupostos do financiamento da educação nacional, mostrando que o país pode e deve aplicar mais recursos para alcançar um desenvolvimento educacional e social adequado. Na segunda, analisam-se documentos do MEC que explicitam as concepções que fundamentam o PDE no que se refere ao financiamento das 40 ações propostas. Na terceira, os autores se posicionam quanto à forma de financiamento adotada e quanto aos recursos previstos ou alocados para a execução das ações. Para finalizar, uma série de questões sobre o plano são levantadas em perspectiva propositiva.

Ocupação de área e interações de golfinhos-rotadores (Stenella longirostris) com o turismo náutico no Arquipélago de Noronha/PE, Brasil

Several works characterize the presence of spinner dolphins at Fernando de Noronha Archipelago in the Dolphins Bay. Though, the dolphins abidance inside this cove has decreased and a new area has been occupied by the animals to achieve the same behaviors, that are resting, breeding and nursing. This area comprises the Inside Sea northeast border of Fernando s de Noronha Island, including the opposing Middle and Dog shore area, the San Antonio Bay and the Between Islands region. The aim was to characterize the dolphins occupation and describe their interactions with the tourism in this area. Data were collected in 2008 and 2009 through a fixed point observation. The study area was divided into seven sub-areas, recording: presence/absence of dolphins, days abidance endurance, abidance length in each area, estimated number of individuals, dolphins direction and speed of displacement, boats presence, interaction period, monitoring, boats attitude and velocity. The dolphins abidance time displayed the same pattern during both years of study, with the higher occupancy in the Between Islands region. Groups with farther than 200 individuals were more frequent both 2008 (46.2%) and 2009 (42.3%). Thus the displacement s slow speed as the preferred direction towards Rat Island also showed the same pattern in both years. The Between Islands region also presented the boats major abidance near the dolphins groups. Boats moved farther in slow speed (95%) than at high speed (5%). The legislation s compliance for the cetaceans protection occurred in 89.7% of 2.839 interactions between boats and spinners, in which this variable was recorded. Whenever boats moved at a slow speed during the meetings with spinner dolphins groups, animals also moved at a slow speed (n = 337), significantly more than the fast displacements (n = 128) ix or "porpoise" (n = 4) (X2 = 318.543, p = -0.001). When boats quickly passed by groups, a significant difference between the dolphins displacement speeds was observed (X2 = 18.264, p =- 0.001), however, the slow (47%) and fast (47% ) displacements frequency was equal, noted the difference with the porpoise displacements (6%), which had the lowest frequency. Data indicate the establishment of a new occupation pattern of the spinner dolphins at Fernando de Noronha, with the Between Islands area being of great importance to the dolphins habits and currently the main area of the boats meeting with the dolphins, showing the need of new conservation measures in this area

Medida da preditividade de instrumentos psicológicos nas avaliações psicológicas de condutores

The object of this study was to identify the possibility of predicting the involvement in traffic infractions from the results of the psychological tests carried out by psychologists specialized in the process of driver licensing in the state of Rio Grande do Norte (RN). The proposal consisted in identifying the penalty points recorded in national driving licenses (CNH) and identifying the corresponding tests and scores obtained, verifying if the average scores in the tests of drivers with and without an infraction record were significantly different and if there is any relation between the test scores and the frequency of the infractions. The results of the psychological instruments were collected in two moments the first being in the act of acquisition of the CNH and the second being during license renewal at the only certified clinic and at the DETRAN-RN. A population of 839 drivers of 14 municipalities were identified. 127 protocols of psychological tests were identified in the records of the DETRAN-RN (2002) and 76 at the clinic (2007), pointing out failures in the process of safekeeping of the psychological material, as well as in its retrieval from the record files. The sample was thus reduced to 68 drivers, all male, with age range between 18 and 41 years old, mean of 21,72 years old (DP = 5,24). 54 drivers were identified without a record of infraction, and 14 with a record. The latter committed 29 infractions. The penalty points recorded in their CNH ranged from 0 to 35 and the typical value of points (median) was zero. In the group with a record of infractions the number of points ranged between 3 and 35, mean of 10,79 (DP = 7,73). Differences were observed in the composition of the battery of tests in the two moments with the same subjects. The use of different tests to assess the same construct of the subject, first and second moment of assessment, did not allow for some analyzes with more efficient statistical proof. It was pointed out that five tests were not carried out and 118 were not corrected/analyzed. Significant differences between the groups were not identified with the psychological instruments used. In another attempt to establish differences between the means, the application of the independent t-Test evidenced a significant difference in the scores of the instruments of concentrated attention in 2002 (t = 2,21, gl = 25, p = 0.037) and of diffuse attention in 2002 (t = 2,37, gl = 24, p = 0.026). The results also did not evidence significant correlation between the scores of the tests and the penalty points of the infractions. Based on this study, it cannot be concluded with precision that the high or low scores are good criteria to determine that a driver will commit more or less traffic infractions, nor that the drivers with higher scores in the tests commit less infractions and vice-versa. Furthermore, the problems to find the instruments and the most basic data require a stronger monitoring on the part of the certified clinic and of the DETRAN-RN.

Reproductive responses of rabbit does to a supplemental lighting program

The objective was to investigate whether the productivity of rabbit does can be improved, when natural photoperiod is decreasing, by adopting a supplemental lighting program. Three experiments were conducted involving two groups: control, submitted to the natural decreasing photoperiod, and supplemented with a lighting program which provided 14 h light/24 h beginning at 10 weeks of age. In the first experiment, 20 nulliparous does, 10 from each group, were euthanized 8 h after being presented to a buck; the overall number of follicles, whose diameter exceeded I mm, was determined macroscopically. The right ovaries were collected, histologically analyzed, and electronically measured. In the second experiment, 30 nulliparous does, 15 from each group, were presented to a buck (day 1). Receptive does were euthanized on day 8 to evaluate embryonic survival (number of normal embryos/ovulation rate). In the third experiment, 48 nulliparous does, 24 from each group, were followed from the first presentation to the buck until the weaning of the first litter. The effect of treatment on reproductive and body weight traits of does, and litter performance traits, at birth and weaning, was evaluated. The average number of follicles whose diameter exceeded 1 mm was higher in the treatment group (12.05 +/- 1.07 vs. 8.63 +/- 1.00, P=0.03 7). Receptive does of the treatment group had heavier ovaries relative to those of the control group (790 +/- 59 vs. 470 +/- 64 mg, P=0.004), whereas no treatment difference regarding this trait was found for non-receptive ones. Treatment had a favorable effect on pregnancy rate of total exposed and of receptive does (80.0% vs. 33.3%, P=0.01, and 92.3% vs. 50.0%, P=0.02, respectively). The number of underdeveloped embryos was lower (0.067 +/- 0.380 vs. 2.500 +/- 0.455, P=0.004), embryonic survival up to day 8, and uterus weight was higher in the treatment group (0.839 +/- 0.075 vs. 0.534 +/- 0.087, P=0.033 and 13.83 +/- 0.72 vs. 10.99 +/- 0.84, P=0.037, respectively). Number of presentations tended to be lower (1.32 +/- 0.17 vs. 1.75 +/- 0.16, P=0.077) and adjusted litter size in the first reproductive cycle tended to be higher (7.09 +/- 0.89 vs. 5.22 +/- 0.68, P=0.091) in the treatment group relative to the control.

Biocompatibility of resin-based materials used as pulp-capping agents

Aim To evaluate and compare the response of pulps of rats capped with resin-modified glass-ionomer cement (RMGIC) or self-etching adhesive system.Methodology Class I cavities were prepared on the occlusal surface of 54 maxillary first molars of 27 rats. Pulp exposure was performed on the cavity floor. The following resin-based materials were applied as pulp-capping agents: G1, Clearfil Liner Bond 2V (CLB 2V; Kuraray Co., Japan); G2, Vitrebond (VIT; 3M/ESPE, USA). In group 3 (control group), a calcium hydroxide/saline paste (CH; Labsynth, Brazil) was used. The cavities were restored with amalgam. After 7, 30 and 60 days, the animals were sacrificed and the jaws were processed for microscopic evaluation.Results Despite the inflammatory response caused by the experimental and the control materials at 7 days, pulpal healing associated with calcified barrier formation was observed at 60 days following the pulp therapy. Both resin-based materials promoted a large zone of cell-rich fibrodentine matrix deposition on the pulp horn related to the pulp exposure site, which was larger to VIT than to CLB 2V specimens. Tertiary dentine underneath the fibrodentine matrix was deposited by a layer of elongated pulpal cells. The remaining pulpal tissue exhibited normal histological characteristics. In the control group, healing and dentine-bridge formation was observed at 30 days. Pulpal breakdown occurred only when bacterial infection occurred.Conclusion Both experimental pulp-capping agents allowed pulpal healing characterized by cell-rich fibrodentine and tertiary dentine deposition as well as calcified barrier formation.

Noradrenaline and mixed alpha(2)-adrenoceptor/imidazoline-receptor ligands: effects on sodium intake

The effect of noradrenaline, and mixed ligands to alpha(2)-adrenoceptors (alpha(2)-AR) and imidazoline receptors (IR), injected intracerebroventricularly (i.c.v.), on sodium intake of sodium depleted rats, was tested against idazoxan, a mixed antagonist ligand to alpha(2)-AR and IR. The inhibition of sodium intake induced by noradrenaline (80 nmol) was completely reversed by idazoxan (160 and 320 nmol) injected i.c.v. The inhibition of sodium intake induced by mixed ligands to alpha(2)-AR and IR, UK14,304, guanabenz and moxonidine, was antagonized from 50 to 60% by idazoxan i.c.v. The results demonstrate that noradrenaline, a non-ligand for IR, acts on alpha(2)-AR inhibiting sodium intake. The possibility that either alpha(2)-AR or IR mediate the effect of mixed agonists on sodium intake remains an open question. (C) 1999 Elsevier B.V. B.V. All rights reserved.

Ação de rodas compactadoras de semeadoras submetidas a cargas verticais na deformação do solo

Uma semeadura bem realizada é fundamental para o sucesso de implantação de uma cultura e as rodas compactadoras utilizadas nessa operação devem ser capazes de melhorar o contato solo-semente para promover boa emergência das plântulas. Com o presente trabalho teve-se por objetivo estudar a influência de três modelos de rodas compactadoras submetidas a diferentes níveis de carga vertical, sobre parâmetros físicos do solo, em uma pista de ensaios projetada para essa finalidade. O trabalho foi desenvolvido no município de Uberaba, MG, em LATOSSOLO Vermelho distrófico, textura média, preparado com enxada rotativa. O delineamento experimental utilizado foi o de blocos ao acaso, com 3 tratamentos e quatro repetições. Os modelos de rodas 1 e 2 apresentaram melhores coeficientes de correlação para as equações obtidas nos diagramas pressão-deformação do que a equação obtida com a roda 3.

Uso da alga Lithothamnium calcareum como fonte alternativa de cálcio nas rações de frangos de corte

Objetivou-se, com este trabalho, avaliar o uso da alga Lithothamnium calcareum (Pallas) Areschoug nas rações para frangos de corte de 1 a 21 e 21 a 42 dias de idade, em substituição à fonte de cálcio tradicional (calcário calcítico). Para isso, foram utilizados 300 pintos machos, da linhagem Cobb®, que receberam rações contendo o calcário calcítico e a alga Lithothamnium calcareum (colhida de inteira e na forma de areia biodentrítica) como fontes de cálcio. O delineamento experimental utilizado foi o inteiramente casualizado, com três tratamentos e cinco repetições de 20 aves cada. As variáveis analisadas foram: ganho de peso (g/ave), consumo de ração (g/ave) e conversão alimentar (g/g). No final do experimento foram avaliados os parâmetros ósseos: peso da tíbia (g), comprimento da tíbia (mm), diâmetro da tíbia (mm) e teor de cinzas na tíbia (%). Na fase inicial (1 a 21 dias) houve efeito (P<0,05) entre os tratamentos para o ganho de peso e conversão alimentar, sendo que o tratamento controle apresentou melhores resultados. Para a fase de crescimento (21 a 42 dias) e período total (1 a 42 dias) não houve efeito entre os tratamentos estudados. A utilização da alga Lithothamnium calcareum (independente da forma de colheita) em substituição à fonte de cálcio tradicional (calcário calcítico) pode ser recomendada para as rações de frangos de corte, sem prejudicar o desempenho zootécnico. Porém, deve-se levar em consideração a viabilidade econômica do uso dessa fonte alternativa nas rações.

Phase transition in poly(vinylidene fluoride) investigated with micro-Raman spectroscopy

The phase transition from the non-polar a-phase to the polar beta-phase of poly(vinylidene fluoride) (PVDF) has been investigated using micro-Raman spectroscopy, which is advantageous because it is a nondestructive technique. Films of alpha-PVDF were subjected to stretching under controlled rates at 80 degrees C, while the transition to P-PVDF was monitored by the decrease in the Raman band at 794 cm(-1) characteristic of the a-phase, along with the concomitant increase in the 839 cm-1 band characteristic of the P-phase. The alpha ->beta transition in our PVDF samples could be achieved even for the sample stretched to twice (2 X -stretched) the initial length and it did not depend on the stretching rate in the range between 2.0 and 7.0 mm/min. These conclusions were corroborated by differential scanning calorimetry (DSC) and X-ray diffraction experiments for PVDF samples processed under the same conditions as in the Raman scattering measurements. Poling with negative corona discharge was found to affect the a-PVDF morphology, improving the Raman bands related to this crystalline phase. This effect is minimized for films stretched to higher ratios. Significantly, corona-induced effects could not be observed with the other experimental techniques, i.e., X-ray diffraction and infrared spectroscopy.
