Valorização do magistério da educação básica no RN: participação do SINTE e do governo estadual na implementação do piso salarial profissional nacional na rede pública estadual no ano de 2009

This paper analyzes the policy of upgrading the teaching profession in relation to financing basic education, with a view to participation of the Union of Education Workers of Rio Grande do Norte - SINTE / RN and the state government in the implementation of Professional Base Salary the National Professional Teaching Public Basic Education - Law 11738/2008, the public state of Rio Grande do Norte. The participation of civil society, through the union movement presents itself as an important process of implementation of Professional Base Salary. The participation of SINTE / RN occurred since the fight to pass the plan, careers and Compensation (2006) until the implementation of the Base Salary (2009) highlighting the power relations established between the Union and State Government. To this end, there were actions such as public hearings and strikes by education professionals. In order to raise issues relevant to the issue of enhancement of teaching and participation of unions as a collective representation has been taken as a theoretical and methodological literature on the financing of basic education, enhancing teaching and participation as well as policy guidelines governing the career of teaching. Was used as a methodological procedure to document analysis and information gathering through semi-structured interviews. The results indicate the participation and the power relationship between the trade union movement and the state government in the implementation of the Base Salary. However, the current issues concerning the limitations of recovery of the teaching profession in order to implement the policy floor, not only merit of the state of Rio Grande do Norte, but the decisions that have been taken by the Supreme Court (STF) relating to the unconstitutionality of Action (ADI) filed by five governors. This fact greatly reduced the possibility of recovery of the teaching of the state, considering that the government was limited to decisions of the Supreme Court. Therefore, the enhancement of teaching remains a challenge for the union movement

Eficácia do herbicida amicarbazone aplicado sobre a palha ou no solo no controle de plantas daninhas na cultura da cana-de-açúcar

A eficácia dos herbicidas no sistema de cana-crua é diretamente influenciada pela quantidade e distribuição de palha na área, bem como pela ocorrência da primeira chuva superior a 20 mm posterior à aplicação, uma vez que a palha é capaz de interceptar o herbicida antes que este atinja o solo. Nesse contexto, a presente pesquisa teve como objetivo avaliar a eficácia e o comportamento do herbicida amicarbazone no controle de plantas daninhas no sistema de cana-crua. Para isso, foi realizado um experimento em condições controladas, considerando diferentes doses de amicarbazone (D1 = 1,05 kg ha-1, D2 = 0,875 kg ha-1, D3 = 0,700 kg ha-1 e D4 = 0,525 kg ha-1) e situações de aplicação desse herbicida, a saber: sobre 5 t de palha ha-1, sobre o solo e coberto com 5 t de palha ha-1, além de pulverização sobre o solo sem cobertura de palha, resultando assim em 12 tratamentos. Aos 7, 14, 21 e 28 dias após a aplicação (DAA), foi avaliada a porcentagem de controle das seguintes espécies de plantas daninhas: Ipomoea grandifolia, Brachiaria decumbens, Merremia cissoides e Euphorbia heterophylla. Pelos resultados obtidos, pode-se constatar que, independentemente da espécie de planta daninha avaliada, os maiores índices de controle foram observados quando o amicarbazone foi aplicado sobre a palha, simulando-se em seguida precipitação correspondente a 30 mm de chuva, e nos tratamentos em que o herbicida foi aplicado diretamente no solo sem palha. Dessa forma, para as espécies I. grandifolia, M. cissoides e E. heterophylla, todos os tratamentos apresentaram excelente controle (nota 6 - 100%) a partir dos 14 DAA; para B. decumbens, o controle total ocorreu aos 28 DAA. Portanto, pode-se concluir que o amicarbazone é uma excelente alternativa para o manejo dessas espécies de plantas daninhas em cana-crua.

Do útero à adoção: a experiência de mulheres férteis que adotaram uma criança

Even with all changes and ruptures related to the social roles that woman had performed, the literature had confirmed that the motherhood still configures it like one of the main roles that she hopes to play in some moment of her life. When the woman did not get pregnant or take ahead a pregnancy, some women find in adoption an alternative to play this role. This research aimed to understand the experience of being mother for adoption in the case of fertile women, but whose partner is infertile. Supported by existential-phenomenological theory, used it the narrative, how methodological instrument. Participated five women, whose adoption process followed the legal ways in the Youngness and Infancy Judgeship of Natal/RN. The results showed that in the selfish training, the woman to see herself how whose role principal is to generate children, although, she think that is natural her participation in others activities go out home too. In male infertile case is a tendency that the woman strikes the infertile status too. The adoption is an alternative to fulfill her desire of being a mother and, meanwhile, please her husband and guarantee the continuity of her love relationship. Through motherly care, the woman discover herself as a mother, what brings a new meaning for her live, independent of to generate a child. Though, exit frustration, sometimes, in association with suffering, on account of the pregnancy and childbirth absence. The end of the research suggests reflections that to become fulfilled herself as mother, the woman does not need, necessarily, to generate a child, being the maternity one of the uncountable possibilities that are shown, and that she can choose, or not, accomplish it

Is The amphibian tree of life really fatally flawed?

Wiens (2007, Q. Rev. Biol. 82, 55-56) recently published a severe critique of Frost et al.'s (2006, Bull. Am. Mus. Nat. Hist. 297, 1-370) monographic study of amphibian systematics, concluding that it is a disaster and recommending that readers simply ignore this study. Beyond the hyperbole, Wiens raised four general objections that he regarded as fatal flaws: (1) the sampling design was insufficient for the generic changes made and taxonomic changes were made without including all type species; (2) the nuclear gene most commonly used in amphibian phylogenetics, RAG-1, was not included, nor were the morphological characters that had justified the older taxonomy; (3) the analytical method employed is questionable because equally weighted parsimony assumes that all characters are evolving at equal rates; and (4) the results were at times clearly erroneous, as evidenced by the inferred non-monophyly of marsupial frogs. In this paper we respond to these criticisms. In brief: (1) the study of Frost et al. did not exist in a vacuum and we discussed our evidence and evidence previously obtained by others that documented the non-monophyletic taxa that we corrected. Beyond that, we agree that all type species should ideally be included, but inclusion of all potentially relevant type species is not feasible in a study of the magnitude of Frost et al. and we contend that this should not prevent progress in the formulation of phylogenetic hypotheses or their application outside of systematics. (2) Rhodopsin, a gene included by Frost et al. is the nuclear gene that is most commonly used in amphibian systematics, not RAG-1. Regardless, ignoring a study because of the absence of a single locus strikes us as unsound practice. With respect to previously hypothesized morphological synapomorphies, Frost et al. provided a lengthy review of the published evidence for all groups, and this was used to inform taxonomic decisions. We noted that confirming and reconciling all morphological transformation series published among previous studies needed to be done, and we included evidence from the only published data set at that time to explicitly code morphological characters (including a number of traditionally applied synapomorphies from adult morphology) across the bulk of the diversity of amphibians (Haas, 2003, Cladistics 19, 23-90). Moreover, the phylogenetic results of the Frost et al. study were largely consistent with previous morphological and molecular studies and where they differed, this was discussed with reference to the weight of evidence. (3) The claim that equally weighted parsimony assumes that all characters are evolving at equal rates has been shown to be false in both analytical and simulation studies. (4) The claimed strong support for marsupial frog monophyly is questionable. Several studies have also found marsupial frogs to be non-monophyletic. Wiens et al. (2005, Syst. Biol. 54, 719-748) recovered marsupial frogs as monophyletic, but that result was strongly supported only by Bayesian clade confidence values (which are known to overestimate support) and bootstrap support in his parsimony analysis was < 50%. Further, in a more recent parsimony analysis of an expanded data set that included RAG-1 and the three traditional morphological synapomorphies of marsupial frogs, Wiens et al. (2006, Am. Nat. 168, 579-596) also found them to be non-monophyletic.Although we attempted to apply the rule of monophyly to the naming of taxonomic groups, our phylogenetic results are largely consistent with conventional views even if not wth the taxonomy current at the time of our writing. Most of our taxonomic changes addressed examples of non-monophyly that had previously been known or suspected (e.g., the non-monophyly of traditional Hyperoliidae, Microhylidae, Hemiphractinae, Leptodactylidae, Phrynobatrachus, Ranidae, Rana, Bufo; and the placement of Brachycephalus within Eleutherodactylus, and Lineatriton within Pseudoeurycea), and it is troubling that Wiens and others, as evidenced by recent publications, continue to perpetuate recognition of non-monophyletic taxonomic groups that so profoundly misrepresent what is known about amphibian phylogeny.

Associativismo e comportamento eleitoral na eleição de 2002

A autora analisa a participação eleitoral em 2002, relacionando-a às formas de participação associativa. A hipótese testada é de que o eleitor com vínculos associativos tem maior participação eleitoral. Nesse sentido, os resultados sugerem que para os eleitores ativos há um perfil associado à participação em greves e filiação sindical mas, quanto à sua filiação partidária, sugerem que há outros fatores intervenientes na relação.

Niobium filtration of conventional and high-frequency x-ray generator beams for intraoral radiography. Effects on absorbed doses, image density and contrast, and photon spectra

We have studied the effects of niobium beam filtration on absorbed doses, on image density and contrast, and on photon spectra with conventional and high-frequency dental x-ray generators. Added niobium reduced entry and superficial absorbed doses in periapical radiography by 9% to 40% with film and digital image receptors, decreased the radiation necessary to produce a given image density on E-speed film and reduced image contrast on D- and E-speed films. As shown by increased half-value layers for aluminum, titanium, and copper and by pulse-height analyses of beam spectra, niobium increased average beam energy by 6% to 19%. Despite the benefits of adding niobium on patient dose reduction and on narrowing the beams' energy spectra, the beam can be overhardened. Adding niobium, therefore, strikes the best balance between radiation dose reduction and beam attenuation, with its risks of increased exposure times, motion blur, and diminished image contrast, when it is used at modest thicknesses (30 μm) and at lower kVp (70) settings. © 1995 Mosby-Year Book, Inc.

A new rain-operated seed dispersal mechanism in Bertolonia mosenii (Melastomataceae), a Neotropical rainforest herb

Although widespread among fungi, lichens, liverworts, and mosses, seed dispersal mechanisms operated by rain are unusual among flowering plants. Generally speaking, two mechanisms are involved in seed dispersal by rains: the splash-cup and the springboard. Here we describe a new seed dispersal mechanism operated by rain in a Neotropical rainforest herb Bertolonia mosenii Cogniaux (Melastomataceae). The study was carried out at the lowland Atlantic rainforest, southeastern Brazil. We experimentally demonstrate that rain is necessary to release the seeds from the capsules through what we call squirt-corner seed dispersal mechanism: when a raindrop strikes the mature fruit, the water droplet forces the seeds outward to the angles (corners) of the triangular capsule and the seeds are released. As far as we know squirt-corner represents a new rain-operated seed dispersal mechanism, and a novel seed dispersal mode both for Melastomataceae and for flowering plants from Neotropical forests.

Mapeamento geoambiental como subsídio na determinação de áreas de instabilidades da faixa de dutos Osvat/Osplan - São Sebastião, SP

Works of linear engineering such as roads, pipelines and transmission lines have specific mapping due to their large scale impact on the environment, thus requiring mapping methods that are both efficient and of low cost. This paper presents a proposal of Geoenvironmental mapping for works linear. The work chosen for the implementation of the method was the Osvat/Osplan pipeline located in the cities of São Sebastião and Caraguatatuba. The geoenvironment mapping was elaborate trough photo-interpretation of images of the ETM+/Landsat-7 sensor and analysis of the drainage network, thus resulting in the partitioning of the geoenvironmental units and the fracture area (structural lineaments and lines of strikes), these maps were subsequently integrated into a product called Map of environmental susceptibility to gravitational and erosive processes, which helped define the areas with potential geotechnical problems that could damage both the pipeline and the environment.

Análise de fraturamentos para determinação de áreas instáveis na faixa de dutos Osvat/Osplan - São Sebastião, em São Paulo

The present work aimed at characterizing geological features that identify areas with high ruptibility (fracturing) in the Osvat/Osplan pipeline in São Sebastião, São Paulo. The analysis of ruptile geological structures (lines of strikes and structural lineaments) through the use of orbital remote sensing was used as systematic mapping. The analysis of these features enables the inference of factors, such as permeability, infiltration and degree of shear in the region, factors which influence the processes of erosion and landslides in the area. On the map of structural lineaments, points of lineaments intersection from different directions were analyzed, followed by the counting of the frequency of these items per unit area, allowing the statistical modeling of spatial distribution, generating the map of density of structural lineament intersections, which allows determining areas with the highest percolation of fluid in the rock structure. However, on the map of lines of strikes, a space analysis was conducted to identify the two directions with higher frequency of lines of strikes in order to establish the maximums 1 and 2 and to identify the areas of abrupt changes of direction of these strike lines. In such areas where abrupt changes of directions of maximum lines of strikes occur, consequently there will be intense percolation of fluids, responsible for higher alterability of the rock/soil complex, facilitating the installation of erosion processes and landslides, increasing the area instability and consequently the vulnerability of the pipeline.
