This second and concluding part of a comprehensive palynological study of the Lower to Middle Ordovician succession of the central-northeastern Canning Basin completes the systematic documentation of the palynomorphs, i.e., chitinozoans, and formulates a palynostratigraphic zonation scheme embracing all three constituent formations of this investigation, viz., the Willara, Goldwyer, and Nita formations. A total of 21 species of chitinozoans (five genera), detailed systematically herein, are identified. Although chitinozoan recovery per sample proved variable, the following species occur fairly persistently in the productive samples: Belonechitina micracantha, Conochitina subcylindrica, C. poumoti, C. langei, Calpichitina windjana, and Rhabdochitina magna. Five, stratigraphically successive acritarch/prasinophyte assemblage zones, ranging in age from early Arenig through late Llanvirn, are proposed as follows (ascending order): Athabascaella rossii Assemblage Zone (corresponding to the lower Willara Formation; and dated as early-mid Arenig); Comasphaeridium setaricum Assemblage Zone (upper Willara and lowermost Goldwyer; late Arenig-earliest Llanvirn); Sacculidium aduncum Assemblage Zone (lower Goldwyer; early Llanvirn); Aremorica-nium solaris Assemblage Zone (middle and lower upper Goldwyer; mid Llanvirn); and Dactylofusa striatogranulata Assemblage Zone (upper Goldwyer and lower Nita; late Llanvirn). Four chitinozoan assemblage zones, stratigraphically coinciding (within the limits of sampling) with the acritarch/prasinophyte zones, comprise (in ascending order): Lagenochitina combazi Assemblage Zone (equivalent to the A. rossii and L. heterorhabda Assemblage Zones); Conochitina langei Assemblage Zone; Conocbitina subcylindrica Assemblage Zone; and Belonecbitina micracantha Assemblage Zone. Chronostratigraphic assignments are based principally on associated conodont and graptolite faunas. Whereas the acritarch/prasinophyte zones bear scant similarities to those established globally elsewhere, the chitinozoan zones show significant affiliations with those known from Laurentia.

Freshwater is extremely precious; but even more precious than freshwater is clean freshwater. From the time that 2/3 of our planet is covered in water, we have contaminated our globe with chemicals that have been used by industrial activities over the last century in a unprecedented way causing harm to humans and wildlife. We have to adopt a new scientific mindset in order to face this problem so to protect this important resource. The Water Framework Directive (European Parliament and the Council, 2000) is a milestone legislative document that transformed the way that water quality monitoring is undertaken across all Member States by introducing the Ecological and Chemical Status. A “good or higher” Ecological Status is expected to be achieved for all waterbodies in Europe by 2015. Yet, most of the European waterbodies, which are determined to be at risk, or of moderate to bad quality, further information will be required so that adequate remediation strategies can be implemented. To date, water quality evaluation is based on five biological components (phytoplankton, macrophytes and benthic algae, macroinvertebrates and fishes) and various hydromorphological and physicochemical elements. The evaluation of the chemical status is principally based on 33 priority substances and on 12 xenobiotics, considered as dangerous for the environment. This approach takes into account only a part of the numerous xenobiotics that can be present in surface waters and could not evidence all the possible causes of ecotoxicological stress that can act in a water section. The mixtures of toxic chemicals may constitute an ecological risk not predictable on the basis of the single component concentration. To improve water quality, sources of contamination and causes of ecological alterations need to be identified. On the other hand, the analysis of the community structure, which is the result of multiple processes, including hydrological constrains and physico-chemical stress, give back only a “photograph” of the actual status of a site without revealing causes and sources of the perturbation. A multidisciplinary approach, able to integrate the information obtained by different methods, such as community structure analysis and eco-genotoxicological studies, could help overcome some of the difficulties in properly identifying the different causes of stress in risk assessment. In synthesis, the river ecological status is the result of a combination of multiple pressures that, for management purposes and quality improvement, have to be disentangled from each other. To reduce actual uncertainty in risk assessment, methods that establish quantitative links between levels of contamination and community alterations are needed. The analysis of macrobenthic invertebrate community structure has been widely used to identify sites subjected to perturbation. Trait-based descriptors of community structure constitute a useful method in ecological risk assessment. The diagnostic capacity of freshwater biomonitoring could be improved by chronic sublethal toxicity testing of water and sediment samples. Requiring an exposure time that covers most of the species’ life cycle, chronic toxicity tests are able to reveal negative effects on life-history traits at contaminant concentrations well below the acute toxicity level. Furthermore, the responses of high-level endpoints (growth, fecundity, mortality) can be integrated in order to evaluate the impact on population’s dynamics, a highly relevant endpoint from the ecological point of view. To gain more accurate information about potential causes and consequences of environmental contamination, the evaluation of adverse effects at physiological, biochemical and genetic level is also needed. The use of different biomarkers and toxicity tests can give information about the sub-lethal and toxic load of environmental compartments. Biomarkers give essential information about the exposure to toxicants, such as endocrine disruptor compounds and genotoxic substances whose negative effects cannot be evidenced by using only high-level toxicological endpoints. The increasing presence of genotoxic pollutants in the environment has caused concern regarding the potential harmful effects of xenobiotics on human health, and interest on the development of new and more sensitive methods for the assessment of mutagenic and cancerogenic risk. Within the WFD, biomarkers and bioassays are regarded as important tools to gain lines of evidence for cause-effect relationship in ecological quality assessment. Despite the scientific community clearly addresses the advantages and necessity of an ecotoxicological approach within the ecological quality assessment, a recent review reports that, more than one decade after the publication of the WFD, only few studies have attempted to integrate ecological water status assessment and biological methods (namely biomarkers or bioassays). None of the fifteen reviewed studies included both biomarkers and bioassays. The integrated approach developed in this PhD Thesis comprises a set of laboratory bioassays (Daphnia magna acute and chronic toxicity tests, Comet Assay and FPG-Comet) newly-developed, modified tacking a cue from standardized existing protocols or applied for freshwater quality testing (ecotoxicological, genotoxicological and toxicogenomic assays), coupled with field investigations on macrobenthic community structures (SPEAR and EBI indexes). Together with the development of new bioassays with Daphnia magna, the feasibility of eco-genotoxicological testing of freshwater and sediment quality with Heterocypris incongruens was evaluated (Comet Assay and a protocol for chronic toxicity). However, the Comet Assay, although standardized, was not applied to freshwater samples due to the lack of sensitivity of this species observed after 24h of exposure to relatively high (and not environmentally relevant) concentrations of reference genotoxicants. Furthermore, this species demonstrated to be unsuitable also for chronic toxicity testing due to the difficult evaluation of fecundity as sub-lethal endpoint of exposure and complications due to its biology and behaviour. The study was applied to a pilot hydrographic sub-Basin, by selecting section subjected to different levels of anthropogenic pressure: this allowed us to establish the reference conditions, to select the most significant endpoints and to evaluate the coherence of the responses of the different lines of evidence (alteration of community structure, eco-genotoxicological responses, alteration of gene expression profiles) and, finally, the diagnostic capacity of the monitoring strategy. Significant correlations were found between the genotoxicological parameter Tail Intensity % (TI%) and macrobenthic community descriptors SPEAR (p<0.001) and EBI (p<0.05), between the genotoxicological parameter describing DNA oxidative stress (ΔTI%) and mean levels of nitrates (p<0.01) and between reproductive impairment (Failed Development % from D. magna chronic bioassays) and TI% (p<0.001) as well as EBI (p<0.001). While correlation among parameters demonstrates a general coherence in the response to increasing impacts, the concomitant ability of each single endpoint to be responsive to specific sources of stress is at the basis of the diagnostic capacity of the integrated approach as demonstrated by stations presenting a mismatch among the different lines of evidence. The chosen set of bioassays, as well as the selected endpoints, are not providing redundant indications on the water quality status but, on the contrary, are contributing with complementary pieces of information about the several stressors that insist simultaneously on a waterbody section providing this monitoring strategy with a solid diagnostic capacity. Our approach should provide opportunities for the integration of biological effects into monitoring programmes for surface water, especially in investigative monitoring. Moreover, it should provide a more realistic assessment of impact and exposure of aquatic organisms to contaminants. Finally this approach should provide an evaluation of drivers of change in biodiversity and its causalities on ecosystem function/services provision, that is the direct and indirect contributions to human well-being.

A pesquisa aborda a violência psicológica tal como é definida pela Organização Mundial de Saúde (KRUG, 2002) Usamos também a definição de violência psicológica utilizada por Straus e Sweet (1992). Nosso objetivo geral foi identificar a ocorrência de violência psicológica conjugal entre estudantes universitários, e a correlação desta com fatores de risco. E os específicos foram verificar sua correlação com a auto-estima, a ingestão de álcool, a faixa etária, o número de filhos e o rendimento familiar dos participantes. Tivemos respondentes de ambos os gêneros, casados ou em união estável, com idades entre 16 e 60 anos e alunos da Universidade Metodista de São Paulo. A pesquisa de campo foi realizada na Universidade Metodista de São Paulo e abordou universitários da graduação, graduação tecnológica e cursos seqüenciais. Esta pesquisa é uma pesquisa descritiva e sua amostragem foi não-probabilística de conveniência, responderam ao instrumento 246 pessoas, que foram escolhidas com base nos critérios de inclusão e na sua disponibilidade imediata para responder à pesquisa. Obtivemos mais respondentes do gênero feminino (145) do que do masculino (100). O instrumento foi composto por: Escala de Táticas de Conflito (CTS1), Escala de Auto-Estima e Autoconceito de Rosenberg e um Questionário Sócio-demográfico Adaptado. A CTS 1 foi usada para medir a violência familiar, a escala de auto-estima foi usada para verificar a atitude positiva ou negativa das pessoas e o questionário foi usado para complementar dados sobre a história pessoal e conjugal dos respondentes. Foram analisados 246 instrumentos através do Estatístico SPSS 13,0 for Windows. Os resultados demonstraram que aproximadamente 30% das pessoas de ambos os gêneros e da amostra total apresentaram alto grau de violência psicológica. Verificamos que existe uma tendência de que quanto menor a auto-estima dos respondentes maior o grau de violência psicológica. Constatamos também a inexistência de correlação linear entre violência psicológica, costume de ingerir bebida alcoólica e quantidade de bebida alcoólica ingerida pelos respondentes. Este dado não é corroborado pela literatura pesquisada. Portanto, percebemos que o álcool em si diz pouco enquanto fator de risco para a ocorrência da violência psicológica. Sua articulação merece ser mais investigada e melhor delineada por meio da busca de conhecimentos e práticas que contribuam para a saúde da população. Concluímos que a violência psicológica conjugal muitas vezes é banalizada e tida como natural

In recent years there have been a number of high-profile plant closures in the UK. In several cases, the policy response has included setting up a task force to deal with the impacts of the closure. It can be hypothesised that task force involving multi-level working across territorial boundaries and tiers of government is crucial to devising a policy response tailored to people's needs and to ensuring success in dealing with the immediate impacts of a closure. This suggests that leadership, and vision, partnership working and community engagement, and delivery of high quality services are important. This paper looks at the case of the MG Rover closure in 2005, to examine the extent to which the policy response to the closure at the national, regional and local levels dealt effectively with the immediate impacts of the closure, and the lessons that can be learned from the experience. Such lessons are of particular relevance given the closure of the LDV van plant in Birmingham in 2009 and more broadly – such as in the case of the downsizing of the Opel operation in Europe following its takeover by Magna.

Este estudio analiza los efectos de la política de financiamiento de la educación básica, por intermedio de los Fundos contables, Fundef y Fundeb, y su proposición en valorar el magisterio, considerando las dimensiones de carrera y de la remuneración de los profesores de la red pública estadal de enseñanza del estado de Rio Grande do Norte, en el período entre 1996 y 2010. Para entender las condicionantes de la evaluación de las políticas públicas, se buscó también las contribuciones de Marx (1996) segundo quién “el concreto es concreto” y que la dialéctica del concreto se puede auxiliar en el intento de captar el fenómeno estudiado. Se utilizó aún, el referencial teórico bibliográfico relacionado al financiamiento de la educación y a la valoración del magisterio, a partir de la literatura referente a las dimensiones del objeto (fundef y Fundeb) y (carrera y remuneración). En la investigación documental, además de las legislaciones, directrices nacionales y locales pertinentes, se utilizaron datos referentes a los recursos disponibles en la Finbra. Tesoro Nacional, SIOPE/RN, INEP/MEC, datos de resumen del folio y folio de pagamiento de Secretaria de Estado, de la Educación e de la Cultura (SEEC), y 289 sueldos de 21 profesores. Se realizó entrevista semi estructurada con nueve profesores, referente a la carrera, además de un cuestionario aplicado a 12 profesores relacionado a remuneración. Se considera que en los resultados referentes a los indicadores educacionales, en el período Fundef ocurrió una reducción en las inscripciones de la red pública de enseñanza, como también en las funciones docentes, de la enseñanza base (fundamental), que corresponde a 37%. A partir de la vigencia del Fundeb (2007 – 2010), estos indicadores fueron puestos en ecuación. En todo el período entre 1996 a 2010, ocurre un aumento en las inscripciones de 119,03% y en las funciones docentes de 77,44%. Sobre los datos de financiamiento, se constató que, del mínimo exigido (60%) en la aplicación de recursos de los Fundos en la remuneración del magisterio se aplica en el período de los dos Fundos, pero el mínimo exigido, o sea, 83,29% a 98,89% de los recursos. Los efectos de los Fundos en la carrera de los nueve profesores, considerando la promoción y la progresión, no han sido satisfactorios. En la promoción de los nueve de estos docentes, apenas uno evolucionó el Nivel (titulación), pero retrocedió en la progresión. En la progresión de los nueve profesores, ocho se hallan con la progresión retrasada, entre dos y cinco clases, acumulando un perjuicio que varía de 10% a 45% en su ganancia. La diferencia de una clase a otra corresponde a 5% en la renta anual. Se observa que las ventajas pecuniarias contribuyen con la remuneración con porcentaje más alto que la renta, disminuyendo esta diferencia en el período de Fundeb. Sobre la remuneración, un profesor con 24 años de carrera, con formación (magisterio), no consigue, después de años de profesión, ganar ni siquiera dos salarios mínimos. El profesor con 30 años de carrera, con maestría, tiene una renta, en 2010, correspondiente a menos de tres salarios mínimos, o sea, 2,82 y una remuneración que equivale a poco más de tres salarios mínimos, o sea, 3,66. Si comparamos la profesión de magisterio con otras que igual exigen formación superior, la primera es, en general, de bajo nivel, causando un resultado negativo sobre la búsqueda de la profesión del magisterio. Por los efectos en la remuneración, se concluye que hubo una mejoría, pero aún insuficiente, sobre todo al comparar con el Salario Mínimo Anual. Se evalúa, una vez que los fundos – Fundef y Fundeb – no fueron capaces de promover la valoración del magisterio en las dimensiones de la carrera y de la remuneración. Se constatan algunos resultados negativos en la política de Fundo ya que tendría que ver, principalmente, con la incapacidad de la referida política a valoración de magisterio, siendo una de las causas, o financiamiento con restricción de presupuesto.

The investigation analyze s the role of the municipalities in the ongoing development of literacy teachers, having as a field of study the municipalities of Jaguaruana and Palhano, both in the State of Ceará. The political - educational space adopted as a sample of the study is the p eriod between the years 2003 and 2006, when the emphasis on cooperative action among the federated entities is observed in the Government’s guidelines and Brazilian educational policies, showing the municipal presence in the implementation and execution of these policies. T he historical - dialectical materialistic perspective, understood as an analysis of the social reality as historical elaboration and product of the human praxis, is expressed as the required theoretical - methodological path. The investigatio n is operationalized through interconnected stages: one that involves bibliographical and documental analysis, in which the theoretical input of the research is added, as well as the Federal, State and M unicipal documents accessed ; and another, regarding t he field work, studying the specific character of the object and its mutual rela tionships in the municipalities . The research brings the notion of intergovernmental relationships and cooperative mechanisms as central theoretical tools and, dialoguing with them, ideas such as decentralization, municipalization and municipal autonomy are inserted into a theoretical/practical body, through which the historical and logical aspects of the object are detailed. The study describes and interprets the policies of on going development of literacy teachers with focus on the national guidelines formulated since the 1990’s and on the govern mental incorporation in the national and subnational spaces. In this sense, the analysis is based on the comprehension of the interrel ationship between the municipal policies and the p olicies created by the S tate or Federal G overnments in order to offer ongoing development of literacy teachers. Considering the investigated sample, it shows how the municipal role and the relationships bet ween the State and municipalities of Ceará have emerged, as well as their characteristics regarding the education management policies, taking into account the practices of municipalization and cooperation between the State and municipalities in their histo rical composition. It shows the practices which aim at the ongoing development of literacy teachers observed in the researched municipalities, pointing out the realities and specific marks left by municipal presence in the area, demonstrating the assigned role and the role played. Based on the points of view of the managers interviewed in the municipalities of Jaguaruana e Palhano, it is possible to note the meaning and effectiveness of the policies carried out. With such elements, it discusses the municipa l asymmetries in their homogeneities and heterogeneities rega rding the execution of their federative role. The analysis shows that th e role of the municipalities vary according to the historical, political and social interventions in each municipality. In the fields of formulation and execution of educational policies, the actions of the municipal governments, situated and with expressive interferences, reveal asymmetries in the sense that some municipalities have bigger autonomy and participate more effect ively in the production and distribution of policies than others. In terms of the researched realities, the study shows that taking care of the policies of ongoing development of literacy teachers is not a task that should be assigned exclusively to the mu nicipalities, nonetheless it is a role that they play with varying degrees of success. This role is in fact a joint competence of the federated entities, in the scope the Brazilian cooperative federalism.

The thesis deals with the concepts of technical tra ining of middle level adopted by the Federal Institute of Education, Science and Technology of R io Grande do Norte (IFRN). Discusses these concepts from the four political-pedagogical projects built in the period 1970 to 2010, spanning three institutionalities: Federal Technica l School of Rio Grande do Norte (1970- 1998), Federal Center of Technological Education of Rio Grande do Norte (1999-2008) and IFRN (from 2008) as well as three important politic al contexts of the country: Civil-Military Dictatorship, New Republic and Period of neoliberal ideas in Brazil. The goal is to analyze the configuration of the conceptions of training adopte d in the political-pedagogical projects IFRN, with emphasis on the specificities and (dis) contin uities, placing them in the context of political, economic and educational change in development in t he country. Addresses the relationship work, education and human development in capitalist society, in order to grasp the concept of employee training engendered by that company as wel l as the possibility of a counter- hegemonic formation. We analyze the formation of mi d-level concepts outlined in the educational reforms implemented in the country. We investigate the concepts of training outlined in the political-pedagogical projects IFRN . Makes use of the historical-dialectical materialism, the literature review, the documentary research and interviews were conducted with subjects who participated in the working group coordinator of the drafting of the political- institutional educational projects. The results sho w that the training of workers in capitalist society has a unilateral character; that the traini ng required by the working class is the omnilateral training; that the formative ideas that permeated the educational reforms in the country between 1970 and 2010 were all envisaged by unilateral training; that, in certain contexts, conceptions of technical training medium level outlined in the political-pedagogical projects IFRN reflect the formative perspectives th at guide educational reforms in the country (unilateral training) and, at other times, the inst itution adopts concepts (training omnilateral) that are not consistent with such prospects; and th at between the political-pedagogical projects built from 1970 to 2010 there are more continuities than breaks in relation to the concepts of training adopted. We conclude that the challenge is to institutionalize the IFRN their educational actions omnilateral designing training undertaken in the political-pedagogical project 2009.

Le travail suivant discute le salaire touché par les professeurs et leur rémunération, face à l’implémentation du Fond de Mantenance du Développement de l’Éducation de Base et Valorisation des Professionnels de l’Enseignement (Fundeb), au Système d’Éducation Public de la Municipalité de la ville de Natal, entre les années de 2007 a 2010. L’objectif est l’analyse des repercussions du Funeb pour la rémuneration des enseignants dans le contexte de la politique de financement de l’Éducation de Base e ses propositions de valorisation des enseignants – revennu et rémunération. L’étude s’est utilisé la recherche bibliographique et documentale, les informations relatives à : Éducatif (inscriptions), rémunération (bulletin de salaire et bulletin de paie), budgétaires (recette et dépense) au ressource – microinformations du recensement scolaire (INEP/MEC), SIOPE/FNDE et lo PCCR de la municipalité (LC nº058/2004), et comme donné comparatif on utilise la rémunération et la valeur du salaire minimum national – actualisé par le INPC. À partir de là, les études montrent que dès la Constitution Fédeérale de 1988, il y a eu des changements dans la structure du financement de l’Éducation par la politique de Fonds, iniciée par le Fundef et continuée par le Fundeb, avec des reflets pour la valorisation des enseignants, spécialement, sur la rémunération. Par rapport au revennu, l’étude montre un réajustement à chaque année qui observe, en 2007, un pourcentage de 23,74%, c’est-à´dire, la plus grande de la série historique. Par l’analyse des donnés de revennus on peut observer que les enseignants, au début de leur carrière, présente des réajustement sur leur revennu et rémunération plus petit que celui du Salaire Minimum National, et pourtant les enseignants de niveau supérieur (N1), spécialisation et maîtrise (N2) ont présenté le même pourcentage de croissance de la rémunération pendant cet étude, qui correspond à 14,7%. Le pourcentage pour le professeur docteur a été noté en 33,9%. Par rapport aux enseignants de plus de temps de service, entre 10 et 15 ans, les pourcentages de réajustement ont été différents, car ils montrent des proportions croissantes selon le niveau de formation et le temps de carrière comme enseignant. Malgré le Fundeb présente des progressions, il ne s’est pas encore configuré comme une politique d’amélioration de salaire pour les enseignants. On remarque que pendant l’analyse, il y a une diminuition de proportion entre la valeur de rémunération e la quantité de salaires minimum composant le total, ce qui configure un procès qui exige de plus grands investissements aux salaires des enseignants.

The period known as the Military Dictatorship (1964-1985) was a period of history marked by Brazil's control of state power by the Armed Forces together, this started with the Civil-Military Coup of April 1964. Was characterized as a time where political freedoms of expression and were placed in check by authoritarian and repressive measures taken by the military governments. The sectional potiguar of the Ordem dos Advogados do Brasil (OAB / RN), and the Federal Council of the institution, supported the establishment of this scam, but from the 1970s undertook measures that sought to corroborate the struggles around democracy the country, which has consolidated its image as a defender of democratic order. With the title inspired by the XII Meeting of OAB in October 1988, the research aims to analyze the participation of OAB / RN and its members within the Brazilian democratization. This analysis begins in 1979 with the participation of the entity in discussions Amnesty Policy to the promulgation of the 1988 Constitution, since the Constitution is the beginning of a full rule of law. We seek to understand the object as a space for democratization, combining the concepts of History, Memory and Politics. In the analyzes are guided theoretically by Jacques Le Goff, Pierre Nora, Maurice Halbwachs, Pierre Bourdieu and Hannah Arendt. Be rebuilt the period of democratic rule in the land potiguares birthing shares of OAB / RN, particularly in the following events: Amnesty Policy 1979, the mobilizations around the campaign of "Direct Now" and the 1988 Constitution We make use of legislation. minutes, papers and interviews built on Oral History.

This scientific investigation begins with the recognition of the authorization granted by the Constitutional Legislator to the State for, relativizing its neutrality towards the private sector, intervene in the behavior of economic agents, through different means, including fiscal incentives and tax increases in order to achieve the objectives and directives of the Federal Constitution, as well as achieve the rights and guarantees also described in the Federal Constitution. Demonstrates, however, that this intervention in the private sector has the power to generate both salutary reflections as perverse and divorced goals from what was established by the Federal Constitution and Multilateral Agreements and this is the basis that justifies the relevance of the study: because of the urgency to provide a thorough analysis of the phenomenon of state intervention in the Economic Order, given the importance of its impacts, both for citizens' lives, as well as for the maintenance of the State established as it is nowadays. From this premise, this research examines the issue of tax policies adopted in the country, focusing on tax incentives, comparing its use with the principles of the Economic Order and the General Agreement on Tariffs and Trade - GATT analyzing whether these have been respected or if Brazil adopted unjustified protectionist measures. From this context, this research approximated different branches of the law, developed through literature review in areas such as constitutional law, economic law, tax law, financial law and law and economics. This study verifies the motivations and objectives that underlie the adopted justifications for the use of tax incentives, as well as its results, seeking to empirically answer if its use is reasonable and consistent with the terms enshrined in the Federal Constitution of 1988 and GATT. The answer to this research question will be sought through doctrinal analysis, jurisprudence and hard cases. Thus, the study begins with the historical evolution of extrafiscality, analyzes the principles that should guide the behavior of economic agents. Subsequently analyzes the legal regime of tax incentives and the results achieved by hard cases in which the tax policies with extrafiscal nature were adopted in order to demonstrate the positive and negative consequences arising from the adoption of this type of benefit

This study is about the enhancement of the elementary school in Natal/RN, (PCCR - Law No. 058/2004), concerning to the horizontal promotion through the performance evaluation. It uses as reference the education policy on the legislative field hegemony and the managerial model. The analysis of the teacher´s valorization is based on the policy of Funds (Fundef and Fundeb) in the Brazilian social and educational agenda. The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010).The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010). The thesis argues for the necessity to adopt a direct relationship between career development and horizontal promotion for more others fifteen classes, no matter to any conditioning variables. In addition, the performance shall be evaluated by interval of 25 years to reach at least the provisions decided in the law, which determines the salary adjustment in 5% at every two years, as pointed at the PCCR, about teachers remuneration, and teachers qualifications. A work of a bibliographic and a documental review about the education funding with the purpose of enhancement of educational work, career concepts, and also promotion and evaluation performance as well was performed based on experts authors in this field. The survey was organized with the aim of articulating quantitative and qualitative information, analyzing data from the teacher's salary - payrolls and paychecks - also applying a questionnaire. After the implementation of the PCCR, it was found that the wage indices for horizontal promotion during the teaching career are tied to a strategy for evaluating the performance which disqualifies the teacher‟s salaries in a minimum percentage of 25% (up to 25 years) and there are also elements that disturb the promotion strategy. The national minimum wage was set in three salaries by the PSPN Lei nº11.738/2008 but it never reaches the three salaries at Natal/RN educational system.Otherwise, the elements that structure the horizontal promotion in fifteen classes, throughout the career, flout the minimum years of teaching work, long established in 25 years. In addition, changes in terms in the salary increase depend on individual efforts by professional development through titration. Concerning to the career, despite of the category approving its PCCR, neither this instrument nor the Funds Policy managed to establish regulations were able to cope effective rules for valuing the teachers in the educational district system. It is necessary to ensure, in percentage terms and financial, the real remuneration of teachers with the attainment of horizontal promotion, reviewing the elements that structure the career and the determinants of performance evaluation.

The monoaromatic compounds are toxic substances present in petroleum derivades and used broadly in the chemical and petrochemical industries. Those compounds are continuously released into the environment, contaminating the soil and water sources, leading to the possible unfeasibility of those hydrous resources due to their highly carcinogenic and mutagenic potentiality, since even in low concentrations, the BTEX may cause serious health issues. Therefore, it is extremely important to develop and search for new methodologies that assist and enable the treatment of BTEX-contaminated matrix. The bioremediation consists on the utilization of microbial groups capable of degrading hydrocarbons, promoting mineralization, or in other words, the permanent destruction of residues, eliminating the risks of future contaminations. This work investigated the biodegradation kinetics of water-soluble monoaromatic compounds (benzene, toluene and ethylbenzene), based on the evaluation of its consummation by the Pseudomonas aeruginosa bacteria, for concentrations varying from 40 to 200 mg/L. To do so, the performances of Monod kinetic model for microbial growth were evaluated and the material balance equations for a batch operation were discretized and numerically solved by the fourth order Runge-Kutta method. The kinetic parameters obtained using the method of least squares as statistical criteria were coherent when compared to those obtained from the literature. They also showed that, the microorganism has greater affinity for ethylbenzene. That way, it was possible to observe that Monod model can predict the experimental data for the individual biodegradation of the BTEX substrates and it can be applied to the optimization of the biodegradation processes of toxic compounds for different types of bioreactors and for different operational conditions.
