Caracterização e composição florística de uma comunidade savânica no Rio Grande do Norte, Brasil : subsídios para a conservação

Studies on Brazilian biodiversity are still very few and can observe the difference of knowledge between the different regions of the country. This affirmation can be verified in the investigation to identify the rare species in Brazil and the key biodiversity areas (ACBs). In that study were identified for Brasil 2.256 rare species and 752 ACBs. The Rio Grande do Norte (RN) was the only Brazilian state that has not been identified any rare species and no ACBs, possibly due to the lack of floristic studies in this state. A particular area was selected for this study: an area of ecological tension with savanna physiognomy in Rio do Fogo, RN. This savanna community is represented in RN in a fragment and immersed in restinga and caatinga and was identified and described only through of radar imagens there are no studies to date in loco . We have prepared the following questions about this community savanna: 1) The region delimited and described by through of radar images by the RADAMBRASIL, 1976, can be associated of the Cerrado, in terms of floristic ?; 2) What is the floristic composition of this area? This area includes rare species, endemic or endangered? 3) What is the geographical and phytogeographical distribution of plant species registered in this area? 4) Those plant species registered are endemic or have affinity with other areas phytoecological Brazilian? To answer these questions we performed a floristic inventory of the August 2007 to September/2009. The results are presented in two chapters (manuscripts). The first chapter, titled "The Savannah Rio Grande do Norte: floristic links with other plant formations in the Northeast and Center-West Brazil" was submitted to the Revista Brasileira de Botância. Chapter 1 discusses the phytogeographical distribution of the species, by comparing floristic studies conducted in the Cerrado, Caatinga and Restinga in the Northeast and Cerrado of the Central Brazil. The analysis of data of this study and compilation with other studies indicated that: i) the record of 94 plant species; ii) of total species, about 64% are associated with the Cerrado, the second specialized bibliography, and about 78% as the List of Species of Flora of Brazil. However, about 73% of total species (94) are also distributed in the Caatinga, the Atlantic forest 64%, the Amazon forest 64%, the Pantanal 15% and the Pampa 12%. Floristically the data show that the community studied is influenced by other floras, has a structure where grasses dominate and also because of his appearance the same savanna then be classified as a Savana gramíneo-lenhosa do tabuleiro . Chapter 2, titled "Considerations on the flora of a savanna community in Rio Grande do Norte, northeastern Brazil: Subsidy key area for conservation" was submitted to the Revista Natureza e Conservação. This has the objective of improve the knowledge of flora of Rio Grande do Norte and to identify possible rare species and consequently increase the key areas of biodiversity in Brazil. The data indicated that: i) of 94 species registered in the study area, 40 were new records for the Rio Grande do Norte state; ii) These citations to unpublished state, Stylosanthes montevidensis Vogel (Fabaceae) and Aristida laevis (Nees) Kunth (Poaceae) are indicated for the first time to the Northeast of Brazil; iii) are registered in the area 24 species endemic to Brazil and 63 non-endemic; iv) Aspilia procumbens Baker (Asteraceae) registered in the area is considered a restricted species and micro endemic Rio Grande do Norte, ie rare species; v) Aspilia procumbens is also cited in the category of critically endangered species and Stilpnopappus cearensis Hubber (Asteraceae) a species vulnerable to extinction. This study shows a new area phytoecological in Rio Grande do Norte and indicates the area's potential to contribute with the sites of global significance for biodiversity conservation, either locally, regionally and nationally. This will certainly contribute to respond some targets set by the Global Strategy for Plant Conservation and the Convention on Biological Diversity such as the inventory of vegetal diversity in a region with little collection, which will provide data that contributes to questions and themes related to biodiversity.

Arcabouço geofísico, isostasia e causas do magmatismo cenozóico da província Borborema e de sua margem continental (Nordeste do Brasil)

The Borborema Province (BP) is a geologic domain located in Northeastern Brazil. The BP is limited at the south by the São Francisco craton, at the west by the Parnaíba basin, and both at the north and east by coastal sedimentary basins. Nonetheless the BP surface geology is well known, several key aspects of its evolution are still open, notably: i)its tectonic compartmentalization established after the Brasiliano orogenesis, ii) the architecture of its cretaceous continental margin, iii) the elastic properties of its lithosphere, and iv) the causes of magmatism and uplifting which occurred in the Cenozoic. In this thesis, a regional coverage of geophysical data (elevation, gravity, magnetic, geoid height, and surface wave global tomography) were integrated with surface geologic information aiming to attain a better understanding of the above questions. In the Riacho do Pontal belt and in the western sector of the Sergipano belt, the neoproterozoic suture of the collision of the Sul domain of the BP with the Sanfranciscana plate (SFP) is correlated with an expressive dipolar gravity anomaly. The positive lobule of this anomaly is due to the BP lower continental crust uplifting whilst the negative lobule is due to the supracrustal nappes overthrusting the SFP. In the eastern sector of the Sergipano belt, this dipolar gravity anomaly does not exist. However the suture still can be identified at the southern sector of the Marancó complex arc, alongside of the Porto da Folha shear zone, where the SFP N-S geophysical alignments are truncated. The boundary associated to the collision of the Ceará domain of the BP with the West African craton is also correlated with a dipolar gravity anomaly. The positive lobule of this anomaly coincides with the Sobral-Pedro II shear zone whilst the negative lobule is associated with the Santa Quitéria magmatic arc. Judging by their geophysical signatures, the major BP internal boundaries are: i)the western sector of the Pernambuco shear zone and the eastern continuation of this shear zone as the Congo shear zone, ii) the Patos shear zone, and iii) the Jaguaribe shear zone and its southwestern continuation as the Tatajuba shear zone. These boundaries divide the BP in five tectonic domains in the geophysical criteria: Sul, Transversal, Rio Grande do Norte, Ceará, and Médio Coreaú. The Sul domain is characterized by geophysical signatures associated with the BP and SFP collision. The fact that Congo shear zone is now proposed as part of the Transversal domain boundary implies an important change in the original definition of this domain. The Rio Grande do Norte domain presents a highly magnetized crust resulted from the superposition of precambrian and phanerozoic events. The Ceará domain is divided by the Senador Pompeu shear zone in two subdomains: the eastern one corresponds to the Orós-Jaguaribe belt and the western one to the Ceará-Central subdomain. The latter subdomain exhibits a positive ENE-W SW gravity anomaly which was associated to a crustal discontinuity. This discontinuity would have acted as a rampart against to the N-S Brasiliano orogenic nappes. The Médio Coreaú domain also presents a dipolar gravity anomaly. Its positive lobule is due to granulitic rocks whereas the negative one is caused by supracrustal rocks. The boundary between Médio Coreaú and Ceará domains can be traced below the Parnaíba basin sediments by its geophysical signature. The joint analysis of free air anomalies, free air admittances, and effective elastic thickness estimates (Te) revealed that the Brazilian East and Equatorial continental margins have quite different elastic properties. In the first one 10 km < Te < 20 km whereas in the second one Te ≤ 10 km. The weakness of the Equatorial margin lithosphere was caused by the cenozoic magmatism. The BP continental margin presents segmentations; some of them have inheritance from precambrian structures and domains. The segmentations conform markedly with some sedimentary basin features which are below described from south to north. The limit between Sergipe and Alagoas subbasins coincides with the suture between BP and SFP. Te estimates indicates concordantly that in Sergipe subbasin Te is around 20 km while Alagoas subbasin has Te around 10 km, thus revealing that the lithosphere in the Sergipe subbasin has a greater rigidity than the lithosphere in the Alagoas subbasin. Additionally inside the crust beneath Sergipe subbasin occurs a very dense body (underplating or crustal heritage?) which is not present in the crust beneath Alagoas subbasin. The continental margin of the Pernambuco basin (15 < Te < 25 km) presents a very distinct free air edge effect displaying two anomalies. This fact indicates the existence in the Pernambuco plateau of a relatively thick crust. In the Paraíba basin the free air edge effect is quite uniform, Te ≈ 15 km, and the lower crust is abnormally dense probably due to its alteration by a magmatic underplating in the Cenozoic. The Potiguar basin segmentation in three parts was corroborated by the Te estimates: in the Potiguar rift Te ≅ 5 km, in the Aracati platform Te ≅ 25 km, and in the Touros platform Te ≅ 10 km. The observed weakness of the lithosphere in the Potiguar rift segment is due to the high heat flux while the relatively high strength of the lithosphere in the Touros platform may be due to the existence of an archaean crust. The Ceará basin, in the region of Mundaú and Icaraí subbasins, presents a quite uniform free air edge effect and Te ranges from 10 to 15 km. The analysis of the Bouguer admittance revealed that isostasy in BP can be explained with an isostatic model where combined surface and buried loadings are present. The estimated ratio of the buried loading relative to the surface loading is equal to 15. In addition, the lower crust in BP is abnormally dense. These affirmations are particularly adequate to the northern portion of BP where adherence of the observed data to the isostatic model is quite good. Using the same above described isostatic model to calculate the coherence function, it was obtained that a single Te estimate for the entire BP must be lower than 60 km; in addition, the BP north portion has Te around 20 km. Using the conventional elastic flexural model to isostasy, an inversion of crust thickness was performed. It was identified two regions in BP where the crust is thickened: one below the Borborema plateau (associated to an uplifting in the Cenozoic) and the other one in the Ceará domain beneath the Santa Quitéria magmatic arc (a residue associated to the Brasiliano orogenesis). On the other hand, along the Cariri-Potiguar trend, the crust is thinned due to an aborted rifting in the Cretaceous. Based on the interpretation of free air anomalies, it was inferred the existence of a large magmatism in the oceanic crust surrounding the BP, in contrast with the incipient magmatism in the continent as shown by surface geology. In BP a quite important positive geoid anomaly exists. This anomaly is spatially correlated with the Borborema plateau and the Macaú-Queimadas volcanic lineament. The integrated interpretation of geoid height anomaly data, global shear velocity model, and geologic data allow to propose that and Edge Driven Convection (EDC) may have caused the Cenozoic magmatism. The EDC is an instability that presumably occurs at the boundary between thick stable lithosphere and oceanic thin lithosphere. In the BP lithosphere, the EDC mechanism would have dragged the cold lithospheric mantle into the hot asthenospheric mantle thus causing a positive density contrast that would have generated the main component of the geoid height anomaly. In addition, the compatibility of the gravity data with the isostatic model, where combined surface and buried loadings are present, together with the temporal correlation between the Cenozoic magmatism and the Borborema plateau uplifting allow to propose that this uplifting would have been caused by the buoyancy effect of a crustal root generated by a magmatic underplating in the Cenozoic

Arquitetura deposicional e evolução tectono-estratigráfica das sequências pré-rifte e rifte, na porção central do Vale do Cariri, Bacia do Araripe, NE do Brasil

A complex depositional history, related to Atlantic rifting, demonstrates the geological evolution during the late Jurassic and early Neocomian periods in the Araripe Basin NE Brazil. Based on outcrop, seismic and remote sensing data, a new model of the tectono-stratigraphic evolution of the section that covers the stages Dom João, Rio da Serra and Aratu (Brejo Santo, Missão Velha and Abaiara formations) is presented in this paper. In the stratigraphic section studied, ten sedimentary facies genetically linked to nine architectural elements were described, representing depositional systems associated with fluvial, aeolian and deltaic environments. Based on the relationship between the rates of creation of accommodation space and sediment influx (A / S) it was possible to associate these depositional systems with High and Low accommodation system tracks. These system tracks represent two tectono-sequences, separated by regional unconformities. The Tectono-sequence I, which includes lithotypes from the Brejo Santo Formation and is related to the pre-rift stage, is bounded at the base by the Paleozoic unconformity. This unit represents only a High Accommodation System Track, composed by a succession of pelitic levels interbedded with sandstones and limestones, from a large fluvial floodplain origin, developed under arid climatic conditions. The Tectono-sequence II, separated from the underlying unit by an erosional unconformity, is related to the rift stage, and is composed by the Missão Velha and Abaiara Formation lithotypes. Changes in depositional style that reflect variations in the A / S ratio, and the presence of hydroplastic deformation bands, make it possible to divide this tectonosequence into two internal sequences. Sequence IIA, which includes the lower portion of the Missão Velha Formation and sequence IIB, is composed by the upper section of the Missão Velha and Abaiara Formations The Sequence IIA below, composed only by the Low Accommodation System Track, includes crossbedding sandstones interbedded with massive mudstones, which are interpreted as deposits of sandy gravel beds wandering rivers. Sequence IIB, above, is more complex, showing a basal Low Accommodation System Track and a High Accommodation System Track at the top, separated by an expansion surface. The lower System Track, related to the upper portion of the Missão Velha Formation, is composed by a series of amalgamated channels, separated by erosion surfaces, interpreted as deposits of a belt of braided channels. The High Accommodation System Track, correlated with the Abaiara Unit, is marked by a significant increase in the A / S, resulting in the progradation of a system of braided river deltas with aeolic influence. Regarding tectonic evolution, the stratigraphic study indicates that the Tectonosequence Rift in the Araripe basin was developed in two phases: first characterized by a beginning of rifting, related to Sequence IIA, followed by a phase of syndepositional deformation, represented by sequence IIB. The first phase was not influenced by the development of large faults, but was influenced by a sharp and continuous decrease of accommodation space that permitted a change in depositional patterns, establishing a new depositional architecture. In turn, the stage of syndepositional deformation allowed for the generation of enough accommodation space for the preservation of fluvial-lacustrine deposits and conditioned the progradation of a braided river-dominated delta system.

Petrologia e geocronologia U-Pb do plúton granítico Serra da Rajada, porção central do domínio Rio Piranhas - Seridó, Província Borborema, NE do Brasil

The ediacaran plutonic activity related to the Brasilian/Pan-African orogeny is one of the most important geological features in the Borborema Province, represented along its extension by numerous batholiths, stocks, and dikes.The object of this study, the Serra Rajada Granitic Pluton (SRGP), located in the central portion of the Piranhas-Seridó River Domain is an example of this activity. This pluton has been the subject of cartographic, petrographic, geochronological and lithogeochemical studies and its rocks were characterized by two facies. First, the granitic facies were described as monzogranites consisting of K-feldspar, plagioclase (oligoclase - An23-24%), quartz and biotite (main mafic) and opaque minerals such as titanite, allanite, apatite, and zircon as accessories. Alteration minerals are chlorite, white mica and carbonate. Second, the dioritic facies consist of rocks formed by quartz diorite containing plagioclase (dominant mineral phase), quartz and K-feldspar. Biotite and amphibole are the dominant mafic minerals; and titanite, opaque minerals, allanite, zircon and apatite are the accessories. However, previous geological mapping work in the region also identified the presence of other lithostratigraphic units. These were described as gneisses and migmatites with undifferentiated amphibolite lenses related to the Caicó Complex (Paleoproterozoic) and metasedimentary rocks of the Seridó Group (Neoproterozoic) composed of paragneiss with calc-silicate lenses, muscovite quartzite and biotite schist (respectively, the Jucurutu formations, Equador and Seridó), the host rocks for the SRGP rocks. Leucomicrogranite and pegmatite dikes have also been identified, both related to the end of the Ediacaran magmatism and colluvial- eluvial and alluvial deposits related to Neogene and Quaternary, respectively. Lithogeochemical data on the SRGP granite facies, highlighted quite evolved rocks (SiO2 69% to 75%), rich in alkalis (Na2O+K2O ≥ 8.0%), depleted of MgO (≤ 0.45%), CaO (≤ 1.42%) and TiO2 (≤ 0.36%) and moderate levels of Fe2O3t (2.16 to 3.53%). They display transitional nature between metaluminous and peraluminous (predominance of the latter) with sub-alkaline/monzonitic (High K calcium-alkali) affinity. Harker diagrams show negative correlations for Fe2O3t, MgO, and CaO, indicating mafic and plagioclase fractionation. REE spectrum shows enrichment of LREE relative to heavy REE (LaN/YbN = 23.70 to 10.13), with negative anomaly in the Eu (Eu/Eu* = 0.70 to 0.23), suggesting fractionation or accumulation in the feldspars source (plagioclase). Data integration allows to correlate the SRGP rocks with those described as Calcium-Alkaline Suite of equigranular High K. The crystallization conditions of the SRGP rocks were determined from the integration of petrographic and lithogeochemical data. These data indicated intermediate to high conditions of ƒO2 (mineral paragenesis titanite + magnetite + quartz), parent magma saturated in H2O (early biotite crystallization), tardi-magmatic processes of fluids rich in ƒCO2, H2O and O2 causing part of the mineral assembly to change (plagioclase carbonation and saussuritization, biotite chloritization and opaques Sphenitization). Thermobarometrical conditions were estimated based on geochemical parameters (Zr and P2O5) and CIPW normative minerals, with results showing the liquidus minimum temperature of about800°C and the solidus temperature of approximately 700°C. The final/minimum crystallization pressure are suggested to be between 3 and 5 Kbar. The presence of zoned minerals (plagioclase and allanite) associated with lithogeochemical data in bi-log diagrams for Rb vs. Ba and Rb vs. Sr suggest the role of fractional crystallization as the dominant process in the magmatic evolution of SRGP. U-Pb Geochronological and Sm-Nd isotope studies indicated, respectively, the crystallization age of biotite monzogranite as 557 ± 13 Ma, with TDM model age of 2.36 Ga, and εNd value of -20.10 to the crystallization age, allowing to infer paleoproterozoic crustal source for the magma.

Fatores de longevidade do programa Central do Cidadão no Rio Grande do Norte

The public management reform in Brazil, since 1995, provoked new experiences in public administration. Among the new models of public service the one-stop shopping has distinguished and was adopted at Rio Grande do Norte with the Citizens Center Program. The one-stop shopping assembles in the same place many public services with appropriate structure, enabled human resources and citizens focus processes. The goal of this research was understand how citizens focus processes help to explain Citizens Center Program s longevity. It was made a case study and the research tools were applied with Citizen Center Programs workers and citizen-users at South Unit of Citizen Center Program placed at Via Direta Mall, Natal. The major contributions for Citizen Center Program s longevity were imputed to Basic Operation Processes. The most spoken features in Citizen Center Program mentioned were quality, efficiency, celerity e personal appearance, what demonstrate concern and care with citizen-users. Worker s personal appearance, accommodation, celerity, politeness and attending capacity planning were high evaluated by citizen-users revealing the wisely choice of use a large quality concept and citizenship concept in public administration. Citizen-users also pointed the necessity of refine and enlarge the communication ways that form an essential mechanism to public citizen focus administration. Not ignoring the policy aspect citizen focus processes were noticed like especial management actions that make easier citizen s activities and public service access, what generate satisfaction to citizen-users. It s possible to conclude that the high level approving evaluation of Citizen Center Program consolidates it an especial public policy that serves citizen s necessities e create appropriate legitimacy conditions of the public policy making harder the choice of ending the policy even in more fragile moments strongly contributing for its longevity

Microcrédito emancipatório no nordeste do Brasil? : estudo de caso do Crediamigo Comunidade nos municípios de Caucaia-Ce e Maranguape-Ce

This piece of work consists in a study case of Crediamigo Comunidade, a product from the portfolio of Crediamigo Program of Banco do Nordeste, that uses the methodology of the Comunitary Banks in the concession of low amount loan to poor communities. The main question consists to understand how the Crediamigo Comunidade is characterized faced to the conflict of emancipatory versus liberal paradigms, that exists in the microcredit area. The main objective will analyze how the mechanisms: social capital, empowerment, formation to credit education and better conditions for economic and social issues promoted in the specific objectives of this product, before the dipute between these paradigms. The method adopted analyzed, in a longitudinal perspective, the three years of the product s existence (jun/2005 to jul 2008). Primary and secondary data made possible to identify qualitatively, emancipatory and non emancipatory attributes in the actions and results of Crediamigo Comunidade. It is concluded that the Crediamigo Comunidade works in a liberal logic of the Crediamigo Program, consequently, his focus is not in the emancipation of the poorest clients. The empowerment is individual and not communitary or Freiriano ; the social capital relations enlarges itself in its bounding and bridging ties, but not in its linkage ties, to have access to politic actors and consequently communitary strengthen. All the formation in the Crediamigo is strictly commercial. These characteristics happen by the liberal paradigm in the Crediamigo management and of all of its products, including the Crediamigo Comunidade

Centros históricos e desenvolvimento urbano: um estudo comparativo entre os programas Monumenta no Brasil e Polis em Portugal

Both the end of the twentieth century and the beginning of the twenty-first century have been characterized as a period of major political, economic, social and cultural transformations. Two of the major consequences of the political-economical crisis of the end of last century are the restructuring of capitalist production, and the consolidation of neoliberalism as a worldwide phenomenon. This new world political-economical scenario has influenced, in a dialectic way, the contemporary urban development. In that sense, "new" spatial processes and new paradigms in both urban management and urban planning have gained shape. In this context of urban transformations, the central areas of western cities, also known as historic centers, are being increasingly (re)valued. Since the Second World War, the historic centers urban areas which have great infrastructure and symbolic relevance had been undergoing a process of evasion of population and activities, undeniably linked to the neglect of government authorities. However, in recent decades, the question of historic centers rehabilitation has acquired a growing interest, academically and in political agendas. The object of this dissertation is to focus on how the government of each Brazil and Portugal has dealt with the issue of historic center rehabilitation through programs of urban rehabilitation

Os instrumentos de incentivo à produção e uso de biodiesel no Brasil: uma análise constitucional sob o princípio do desenvolvimento sustentável

The recent insertion of biodiesel derived from oily vegetables in the Brazilian energetic matrix calls for the study of some aspects that belong to it. The analysis of the carbonized energetic pattern concerns the paradigm of economic development that is constitutionally enshrined sustainable development which make environmental protection compatible with the needs of the economic rationality. This text is structured according to the ideas of modern hermeneutic that sees substantial value in the principles capable of create a harmonious relationship between law and society. The study of the constitutional principles to conduct a legal analysis about the National Program for Production and Use of Biodiesel - PNPB. The aim of the research is the study of PNPB ahead with the constitutional principles governing the economic order. To achieve this end we studied the sustainable development as a constitutional principle. We start with the notion that the thematic principles, and fundamental to understanding the dimension of sustainable development institute, since its concept is closely related to the applications of the principles enshrined in virtually all the constitutional order of the Western world. Then this was the National Energy Policy, initiating the approach by guiding principles of the National Energy Policy to develop the theme of public policy in the energy sector. Therefore, we studied the National Program of Biodiesel Production and Use - PNPB. From a technical introduction to the concept of biodiesel and a brief historical background, analyzing their advantages compared to fossil fuels predominantly used. Then it became a regulatory overview of the Brazilian legislation on the subject, central to understanding the plans and objectives pursued by the Brazilian government with encouraging the production of biodiesel. Finally discussed the tax incentives for production and use of biodiesel in Brazil. From the idea of federalism, characterized the tax as an instrument of state intervention in the economy. And finally it brought the tax incentives of Law No. 11.116/2005 in the face of the constitutional principles of economy and tax, and tax incentives from projects related to the Kyoto Protocol

Sistema eleitoral proporcional : uma proposta técnico-politica para o Brasil

The present work aims to analyze the several proportional electoral systems from the contemporaries democracies in order to, in the end, purpose a system that better fits to the constitutional Brazilian order. In this direction, we pursued to indicate the main virtues and imperfections in proportional electoral systems in use in more than two hundred countries, especially relating to the positive and negative effects that these systems inject in the party systems, in the governability and in the representativity. In order to collect elements, and also before getting to the work s main point, other issues were approached, even in a shortened way. Nevertheless, in a position taking, we conclude the work opting for a proportional electoral system that potencializes the constitutional principles of representativity and governability as well as prints a party system strong and strict, once these are the depositaries of a democracy compromised with the Brazilian society

Terceirização versus agenda do trabalho decente : estudo de caso a partir do Banco do Brasil s.a. na Paraíba

This Dissertation examines outsourcing in Bank of Brazil SA, the state of Paraiba. The central research question is to what extent this flexibility of labor relations incorporates items claimed by ´recent´ Decent Work Agenda of the International Labour Organization (OIT) or, on the contrary, the ´epidemic´ of outsourcing makes it even more challenging the world of work in the third millennium. The research hypothesis is that the Bank of Brazil has a growing subcontracting / outsourcing of labor (companies and individuals) and that not only contributes to the deterioration of working conditions, but also opposes the Work Agenda decent. Aiming to prove or disprove the hypothesis, the study includes a survey and secondary field. The literature review focuses on the trend towards casualization of labor in capitalism, and yet, in an effort to systematize data and analysis on ´outsourcing´ from the viewpoint of different actors. This theoretical framework is anchored in important classical sources and present that address the topic in the world and in Brazil. The field research was conducted with the actors related to the theme of ´outsourcing´ the Bank of Brazil - Paraiba, precisely branch managers, permanent employees of the bank, union representatives (bank workers), union bank and outsourced. The results confirm, in part, the study hypothesis, by demonstrating that there are several meanings and forms of precariousness that the contractors surveyed are submitted, highlighting the issue of salaries, the work environment, union representation and health worker. All these themes, each for himself, are contemplated by the Decent Work Agenda of the ILO and show, according to field research, rather fragile

Aí eu era Antônio Brasil: contribuições de situações didáticas com conhecimentos históricos para a construção da identidade pessoal da criança na educação infantil

L'objectif de cette étude est de comprendre la relation entre les situations didactiques faisant appel aux connaissances historiques et la construction de l'identité personnelle pour les enfants dans l'éducation de la petite enfance. Sa question centrale se demande si les connaissances sont offrent des contributions à la construction de l'identité personnelle par les enfants de la petite enfance. Se distingue, lui aussi, entend contribuer à élargir le débat sur l'enseignement et l'apprentissage des thèmes historiques dans l'éducation des enfants, et permettre un dialogue avec d'autres enseignants dans cette étape de l'éducation. Ont été analysés par des principes théoriques et méthodologiques de qualité et a assumé les orientations méthodologiques de la recherche collaborative. Il a été constaté que la systématisation des situations didactiques impliquant la connaissance historique dans l'éducation de la petite enfance contribue à la construction de l'identité personnelle de l'enfant. Ceci, pour prendre possession de ces connaissances, ils recueillent des renseignements qui permet le plus large éventail de relations, afin de comparer les pratiques culturelles de son temps avec des pratiques à d'autres moments. Ainsi orientée, l'enfant cherche à raconter son histoire avec le thème historique à laquelle elle a eu accès, d'organiser et de construire des réponses des explications sur leur environnement et de lui-même. Tout cela montre à la réalisation que le processus d'internalisation des connaissances historiques de l'enfant est construit comme un sujet et, par conséquent, cette connaissance peut être conçu comme un médiateur dans la formation de l'identité personnelle

Política de formação docente na América Latina :Argentina, Brasil e Chile

This work aims at studying the policies of teaching training and their impact in the actors and in the education systems of the countries in which these policies were implemented into the context of neoliberal reforms. We particularly studied these policies in three Latin America countries: Argentina, Brazil and Chile. The policies studied here are the ones implemented from the 90 s. However, the horizon of this study is at the beginning of the 80 s, period that starts one of the four intervention initiatives of education here studied: The Main Project of Education For Latin America and Caribbean (PROMEDLAC), which in 2002 goes into a new stage and it is called Regional Project of Education for Latin America and Caribbean (PRELAC), worked out by UNESCO as a request of government representatives of countries of the region, based on the suggestions of Declaration of Mexico , signed by them in 1979. These suggestions will be in the base of the other three initiatives: The Education For All (EPT); Ibero-American Conferences of Education (CIE) and The Hemisphere Action Plan of Education (PAHE), whose documents are the base to the production of an abundant legislation and normatization on education that created the parameters on which the policies of education reforms were worked out and implemented and the dynamism of our education systems from the last two decades of the twentieth century on. All these initiatives intend to work with objectives, projects and programs that, in some cases, in isolation or in groups, are under influence of their actions in a way that frequently it is difficult to identify which of them is the main responsible for some advances. It is important to stand out that not all of the suggestions produced by these initiatives were implemented as policies, and many of them to be implemented were changed in such a way that they were distorted, even they were a result of a multilateral deal, each country gave to them its own interpretation. Moreover, in all these processes the teaching entities had and keep having a fundamental role. The evidences, result of the evaluations of each initiative, show that education policies implemented produced advances in several aspects. They are still not the ideal ones, in truth, but they do exist. In relation to the teaching questions, there were and are still being implemented multiples and varied actions that did not have the expected impact in the education systems of the countries, objects of this study, but, many of them that go on, are promising and start to have a positive impact into the education systems. Even so, the teaching subject matter, even playing a central role in the agenda of all countries of the region, still represents one of the big challenges to the advance and improvement of our education systems

Guiando almas femininas: a educação protestante da mulher em impressos confessionais no Brasil e em Portugal (1890-1930)

This paper treats confessional printings as a non formal space for the female education. It reflects on the importance of the woman s role to the diffusion of Protestantism in general, and its Presbyterian trend in particular, besides commenting on the proliferation of printings at the First Republic and its relation with education. In this study, Brazilian Northeastern is seen as a relevant space to the diffusion of Protestantism in Brazil; especially on what concerns the relations between Rio Grande do Norte and Pernambuco. Thereby some fountains were fundamental, as the confessional printings, that is, newspapers, magazines, prospects and other materials recollected in archives located in Natal/RN and Recife/PE, and São Paulo. It was also provided a brief incursion on Portuguese confessional printings kept in Oporto, PT. New Cultural History was chosen as theoretic-methodological guide, franchising ways inside the history of book and reading with the help of concepts like Interdependence, Social Configuration (ELIAS, 1993, 1994) and Representation (CHARTIER, 1990), considering that the survey worked out culture-manufactured products that is, intentional materials. It is well known that publishing, or better, the dissemination of printed material used to be associated to Protestants missionary practices since Reform began and, as what concerns the investigated period, in Portuguese and Brazilian lands indistinctly. Printing material in general books, booklets, fragments, as well as the press itself played a central role in divulging reformed ideas, their social options and the means of being and intervening in the world. In this regard, the confessional printings established themselves as an educative, although non schooled, informal space, but, all considered, relevant, seen that they dialogue with another important demand of that social group: formal, literate education. Because it dealt with the diffusion of a printed culture supported by the written word, it required of that group a different modus operandi: formal education. The first letters schools at first, then the high schools later represented spaces established for the circulation of printing material in order that they should be read, divulged and comprehended. This survey intends at last to take a look at Protestantism which, in this context of self-affirmation, reserved a specific place to woman by working out a non formal educational proposal disseminated by printing material. Three models were highlighted in the reformed proposal: Christian education in itself, household education, whose references of motherhood and care towards the neighbor were present and, at last, education to the public space, with emphasis on the practice of teaching. This study also offers a brief dialogue between Brazil and Portugal because, when some periodic printing, book or something like that got to be published in one margin of the Atlantic Ocean, the other margin surely was affected by that feat, received it, divulged it, corroborating the argument in support of the circulation of these printings. It was not only the same language that survived in both maritime coasts; some protestant specificities also crossed out along that sea
