L'étude est basée sur le processus de la transhumance qui se produit sur les rives du Tocantins Itacaiúnas et rivières de la commune de Maraba situé dans l'État sud-est du Para, sur les flux et reflux de nos rivières. La transhumance est due au transfert des ressources humaines temporairement par des contraintes environnementales ou les questions financières. Ce phénomène se produit chaque année à la suite d'inondations constantes qui se produisent dans la ville de Maraba, dans les zones les plus basses de la ville, semblable à ce qui se passe dans pionnier Maraba (ancien Maraba). En raison de cet événement, ces groupes sociaux doivent être mis aux quartiers résidentiels les plus élevés. Les noyaux qui servent de refuge sont la Nouvelle Ville et la Nouvelle Maraba. Cependant, la plupart des sans-abri, comme une question de stratégie et de survie, de finalement passer à des abris temporaires construits par les habitants eux-mêmes ou par la défense civile locale. Le processus de la transhumance se produit souvent des décennies sur les rives des fleuves Itacaiúnas et Tocantins dans la zone urbaine de la municipalité de Maraba. Bien que ce phénomène est lié à une question de mode de vie culturel de la ville côtière, l'un des principaux problèmes concerne une nouvelle main-d'oeuvre des riverains qui vivent dans les villes et ont subi les impacts des changements productifs dans l'environnement urbain. Tout comme nous ne pouvons pas ne pas tenir compte de la création de poches de pauvreté des femmes, des enfants, les migrants et les habitants des bidonvilles à la périphérie des villes, associées à un capitalisme périphérique qui a généré la marginalisation sociale d'une partie de la population (Oliveira, 2007). En outre, riverains, pour des raisons culturelles, sont connectés en permanence avec les rivières et la ville où s'occupe principalement de commerce et la fourniture de services. Le type d'activité de travail se passe comme la dynamique des flux et reflux de l'Amazonie. La recherche sur le terrain a été réalisée en 2012 avec la vie côtière dans la ville et de la souffrance des inondations qui se produisent entre les mois de Janvier à Juin dans la ville de Maraba. Il s'agit d'une étude de cas, étant donné que ce processus migratoire appelé transhumance ou de trajet ou changement de saison se passe en particulier dans cette partie de la ville inondée de Maraba. Diverses sources d'information ont été utilisés, comme les entrevues, l'observation systématique lieu, une source documentaire, les photographies, etc, ainsi que d'une variété de données recueillies par divers informateurs (en bordure de la ville, les pêcheurs, les responsables de la défense civile et les dirigeants Communauté). .

Despite the huge diversity in the Neotropical region, little is known about the biogeography of the subfamily Polistinae. This thesis is divided into three chapters which, despite their distinct specific aims, have as central target the discussion of the influence of environmental, ecological and evolutionary processes on the distribution of genetic diversity and species richness of polistines. For this end, in the first chapter is provided a wide review on the origins of Polistinae and change-promoter processes in the Neotropics. In the second chapter, possible colonization routes used by the subfamily in the Americas are proposed based on the Round-trip hypothesis. Such a hypothesis is corroborated by the recurrence of progression rules, inferred by phylogeny-distribution relationships, pointing more basal clades of several genera occurring in the Amazonian rainforest and more derived clades in eastern South America. The occurrence of an inverse progression rule for Polistes sustains a second rarer and older route from east to west. The third chapter focuses on the disjunction between Amazonia and Atlantic Forest and on the species that, due to changes in forest distributions, had their populations fragmented. It is provided in this study a wide list with 127 Neotropical taxa with disjunct lineages between both forests, climate stability models for eight species (two paper wasps and six vertebrates) and extensive phylogeographies for the wasps Angiopolybia pallens and Synoeca surinama. Such wasp species were used as genetic models to test spatially-esplicit hypotheses of climate stability and were chosen by present distinct ecological characteristics, but occur in sympatry in Amazonia and Atlantic Forest. It was aimed with this to test the following hypothesis: the disjunction affected idiosyncratically the genetic diversity of species with populations widely fragmented. The information presented in the three studies might serve as support in future works on Polistinae biogeography, mainly those that focus on the integration of environmental events to explain both evolutionary and ecological processes.

Recent studies have used low-level laser therapy (LLLT) and LEDs (light-emitting diodes - LEDT) to increase muscle performance in experimental models and randomized clinical trials. However, the effects of these therapies on muscle tissue are not well understood, especially related to their mechanisms of action and clinical use. The objective of this thesis was to investigate the effects of LLLT and LEDT on muscle tissue through in vitro, experimental models and clinical trials to elucidate the main mechanisms of action of these therapies on muscle tissue submitted to fatigue tests and/ or strength training programs to guide the clinical practice. Among the mechanisms of action, we highlight a modulation of mitochondrial metabolism, synthesis of ATP (adenosine triphosphate) and glycogen, muscle cell proliferation, antioxidant defenses and a gene expression modulation quantified by real time polymerase chain reaction (RT-PCR) and microarrays (whole human genome). To accomplish these objectives, we conducted an in vitro study with muscle cell line culture, two experimental studies with animals submitted to fatigue tests and physical training, and five clinical studies that investigated the effects of LLLT and LEDT on muscular pre-conditioning (LLLT/ LEDT application before exercise) and post-exercise muscle recovery (LLLT/ LEDT application after exercise) in athletes, non-athletes and young men genetically comparable (identical twins) submitted to official games of volleyball, sub maximal and maximal tests of effort, and physical training programs, respectively. In vitro, experimental and clinical studies, added to an extensive literature review included in this thesis, allowed us to understand that there is a time-response to muscle cells absorb the energy of lasers/ LEDs and transform that energy into biochemical responses to increase muscle performance in muscular pre-conditioning regimen, or accelerate postexercise muscle recovery. In addition, LLLT/ LEDT applied over the muscle tissue shows also a pattern of dose-response which appears to be dependent of the objective, i.e., prevention of muscle damage or stimulation of energy metabolism, ATP synthesis, gene expression and improved muscle performance.

This work has as its object music in the school context of children from the early years of Elementary School. The theme arose from my concern during the period of mandatory curricular internship held in 2013, when I was struck by the absence of music in the daily lives of children.The research sought to understand why music is still ignored in some school contexts despite being an important component of children's cultural education. The work is divided into three chapters. The first chapter presents the Theoretical Framework. In order to carry out the task of investigating music in the school context of children of the Early Years, in this part of the work, the presence of music since the baby's life was studied; the training of pedagogues in the area of music; interdisciplinarity as an important dimension in school music education; the use of singing in pedagogical practices; the use of free materials in the creation of musical instruments, and the presence of music at school in general. The second chapter contains the research methodology, classified as qualitative and case study, with the constitution of a group of teachers, with whom interviews were conducted. In the third and last chapter, the analysis of the interviews is presented, relating them to the authors of the theoretical basis presented in the first chapter. The results point to the importance of the musical training of pedagogues, of teaching music for the healthy development of children and of pedagogical practices that involve music in school routine.

The indigenous issue presented in the school context on the view of European blueprints may generate numerous misconceptions, reflecting attitudes of prejudice, rejection, discrimination and segregation. Although they represent a group of ethnic-cultural formation of Brazil, their history remains overlooked, covered in the school context as mere individuals from the time of contact with the Europeans, leaving a deep gap regarding the participation of those groups throughout the history of Brazil. Thus, a perspective that is intended to be multicultural and interactive should bring the debate to the classroom on diversity and difference as being dynamic, fluid, and ever-changing processes. Issues that pervade historic school discourses and similar ones, influence the construction process of individual and collective identification of the student. In this research, we aim to draw considerations on school discourses related to indigenous people, and on how the student builds his identification toward those groups, from the discourses that are recognized, accepted, and instituted in the matrix of the Common Basic Curriculum of Minas Gerais, in the subject of history. These perceptions point to an approach based on speeches that gained tradition throughout the history of Brazil, having the European discourse as its core.

Reading is a complex ability that involves a set of discriminated operants. In exposure to discrimination teaching with printed words the elements are combined and recombined in new words that control how to read the new words (recombinative reading). The present study had the objective of investigating whether previous discoveries on recombinative reading with tactile stimuli from the Braille alphabet were replicable. It was investigated the acquisition of pseudowords printed in Braille and the combination and recombination of the textual units in recombinative reading. Four literate adults with acquired visual impairment learned auditory-tactile conditional discriminations between dictated and printed pseudowords in Roman alphabet (AB) and between dictated and printed pseudowords in Braille (AC). Periodic tests evaluated new choice relations (BC, CB, AC) and oral textual responding (CD) with taught and new words. Two experimental studies (with two sets of words) were conducted, they were composed of six teachingtesting cycles (two words in each cycle) with tactile stimuli with font size 90 (Study 1) and size 40 (Study 2). The pseudowords were created to strengthen recombinative reading: four vowels and four consonants composed 4 syllables and formed 12 dissyllable words for teaching and 14 words for tests (each syllable was presented in the first and last position of the words at the same times). The four participants learned all conditional discriminations and formed equivalence classes that included dictated and tactile words in the two modalities. All of them showed scores higher than 80% in the selection of the new words. New words Braille reading showed variability: two participants showed correct responses with scores higher than 75%; the others showed between 41 and 79%. The results replicated and expanding the previous discoveries about to Braille stimuli and their elemental control by within-syllable units can develop recombinative reading. Teaching procedure variables, stimuli modalities, and the elements overlapping in different words had an important role to generate Braille reading.

Non-formal education and public communication of science received broad attention around the globe in recent years, which confirms it as a knowledge field with great potential for the formation of a scientific culture and science education. Within this field, Astronomy constitutes a privileged area due to the existence of a network of institutions across the whole country, the specificities of the community of amateur astronomers and the fascination which the subjects provokes in audiences of all ages. Yet, although the community of academics and educators begins to recognize the unique potential of Astronomy in non-formal education and public communication of science, the area has only been growing slowly and in a disperse manner and still remains ill explored and little analyzed. For example: What are the research trends? What are the shortcomings of the existing literature? Driven by this need for exploration, this study sets out to consolidate and enhance the existing knowledge base on the practice of non-formal education and public communication of science in the context of Brazil being the main objectives to: i) systematize and map the scientific literature on non-formal education and public communication of Astronomy in Brazil; ii) identify trends, priorities, gaps and future directions of the field, based on the opinion of a panel of experts of different backgrounds related to the field of non-formal education and public communication of Astronomy in Brazil; iii) integrate the data obtained from the literature review and the outcome of the consultation of experts to outline a comprehensive picture of the area. In order to achieve these objectives we conducted a state-of-the art review and consulted 86 specialists using the Delphi methodology which consists in a series of successive questionnaires. In terms of methodology qualitative analysis in form of content analysis of the questionnaires and the literature and quantitative analysis in form of descriptive statistic were combined. As expected, the results of the state-of the art review confirmed that research in this area is still in its infancy; only 20 articles could be identified being the majority descriptions of activities. However, in terms of institutions, initiatives and activities the area appears to be very active and heterogeneous and people involved show enthusiasm and dedication. Meanwhile, our Delphi reveals the major problems and barriers which have to be overcome to unlock the full potential of Astronomy in the area of science education. It further provides a controlled discussion on possible solutions suggested by the specialists itself. A majority agrees that the creation of an overarching entity, which co-ordinates, supports and unites the community, would be beneficial to the development and spread of the area. The apparent desire to discuss, reflect and act on how to improve the area - as shown by the community - remains to be underlined. Seen the strong involvement in this study of people actively participating in non-formal education and public communication of science, it is argued that one of the major contribution of this study was to foster and nourish this joint reflection. We hope that our results can provide a starting point for further reflections and actions which result in a better understanding of the area.

The main objective of this study focuses on the identification and analysis of expenditure incurred by rural and urban schools of Paraná with a view to calculating the cost-student, through the analysis of public policies implemented in Brazil and financing in the State of Paraná. We decided to make a documentary research, employing a quantitative and qualitative analysis of the brazilian legislation, contained in their constitutions and expressed by a set of policies that govern and regulate the educational field in our country, in particular its financing. The universe involving our research focused on five rural schools from Arapongas twelve urban schools that accept students from rural and twenty-four urban schools serving children and adolescents in the city of Apucarana. We note that the cost-student for the two schools goes far beyond the minimum set by the Brazilian federal government value, as well as specified by the Paraná state government, on average exceeding them up to four times the minimum value. We understand that the use of accounting, its resources and its instruments used both for display and for the analysis of legislation and public policies that regulate, standardize and manage the brazilian educational field can contribute to improving the school realities of individuals living and work in the field.

The purpose of this research is to understand the formative process developed in a group of mathematics teachers guided in the use of computers inclusion in their pedagogical practices. The question that guided the development of the research was: What are characteristics emerge from the formative process in a collaborative group of mathematics teachers to use computers in their teaching? This research is qualitative, of type participant observation. The data collection was carried out face of meetings a collaborative group of math study entitled Collaborative Study in Mathematics Education Group (CSMEG). Discussions of audio recorded meetings were used; oral and written narratives on the teaching practice; activity of scripts built out from the work proposal with the use of information technology and e-mails from the group on the profile and individual graduation and the sharing activities. For the analysis, we used the theoretical reference on teacher education, especially on reflective practice, collaborative groups and information technology in mathematics teaching. The reading of the data allowed to establish a guiding axis that highlights aspects of content and reflexive dynamics found both in the preparation of mathematical activities and in developing classroom environments with computer technology. From the discussion of the shaft were constructed three categories of analysis: 1. The computer technology insertion on collaborative group; 2. The computer technology insertion on mathematics education; and 3 Reflective practices on collaborative group. The results indicate that the pedagogical practice needs to be the starting point of reflective learning process, as shown in the proposed content and collective choices of the group during construction activities. The computer technology insertion's potentiality of visualizing and development of activities help on exploiting and relations of mathematical concepts. The elaboration of activities with the use of computer technology directed to individual interests contribute to the redefinition of the mathematical concepts and knowledge of the practice. Moreover, the reflective discussions that permeated the elaborations of the activities with the use of computer helped the teachers analyze and build meaningful activities with a look at content, to the student and to their knowledge.

Between 2001 and 2011, the significant reduction in the homicide rate in São Paulo has sparked controversy in public debate and social sciences. What causalities certainly multiple, and analytic assumptions that explain this phenomenon, a São Paulo specificity in the national framework? In 2001 the city of Luzia to be studied here, located in the Metropolitan Region of São Paulo (RMSP), presented homicide rate of 51.57 / 100 000 inhabitants; in 2010 this rate dropped to 5.53 / 100,000 inhabitants, a tenth of the initial value. However, in 2011, further significant increase to 18.11 / 100,000 inhabitants in the city, has blurred the picture even more complex. The objective of this research is to study the truth discourses around litigation and homicides operating in an intersection zone, expanding, between state and local policy in relations between broken and chain. The listed data are based on a living as a resident in the city for over 20 years, and of practice in local organizations, over the 2000s, now recovered in the light of ethnography in the territory, conducted between 2012 and 2013.

From 2010, Brazil ranks as the largest consumer of pesticides in the world, being 99% or more of sprayed pesticides can disseminate to the environment, and consequently reaching the ground and water. A possibility attempt to remedy this contamination is the use of Advanced Oxidation Processes (AOP). These processes consist in formation of highly oxidizing species in a way to mineralize organic molecules. The species can be generated from photoactivation reactions using a semiconductor under ultraviolet-visible radiation. A promising and underexplored semiconductor in catalysis is Nb2O5 which presents notable chemical and physical properties also, niobium is highly available in Brazil and present low cost. This work aimed to evaluate the use of an abundant material in Brazil, niobium, in order to contribute to the resolution of an environmental problem and public health, the water contamination by pesticides. In this way, it tried to draw parallels between the structural, morphological and surface characteristics of the synthesized Nb2O5, and its photocatalytic activity against pesticides. Nb2O5 was synthesized by three different methods, Polymeric Precursors, Hydrothermic and Decomposition. The process was optimized for each method varying different parameters in the employed methodology. The techniques X-ray diffraction (XRD), Scanning Electron Microscopy with Field Emission Gun (SEM-FEG), Zeta Potential, Infrared, Diffuse Reflectance and Raman spectroscopies; were used to characterize the synthesized materials. The photodegradation process under UVC radiation (254 nm) was monitored using UV-spectroscopy in the UV-visible region and its efficiency was evaluated by means of kinetic study. In general, it was found that the polymeric precursors method produces the most efficient Nb2O5 photocatalyst. Thus, this method was used for impregnating the previously synthesized magnetic nanoparticles (magnesium and cobalt ferrites) with Nb2O5, in order to remove the photocatalyst from water and enable to reuse this material. From the obtained results it was observed that the magnetic nanoparticles do not influence the photocatalytic response and may provide the removal and reuse of the photocatalyst.

The Federal Law 11.947 of 2009 provides that states and municipalities, to perform actions of the National School Feeding Programme (PNAE), must spend at least 30% of funds received from the National Fund for the Development of Education (ENDF) to purchase products from family farms. Despite presenting innovative features, such regulation has many challenges. Highlights the need for greater contact and cooperation between government managers and farmers during the PNAE implementation process. The literature that addresses the concept of innovation in the public sector also indicates the importance of inclusion of citizens/users in the design and provision of public actions. Based on these, this research aimed to identify innovative aspects in the PNAE implementation process in Sorocaba-SP. Also aimed to raise inducing aspects and barriers to innovation in this process. Collection and analysis of data, we used a qualitative approach and the method of single case study with multiple units of analysis and multiple sources of data collection. Among the main results, it was found that the participation of the actors involved in PNAE presented two different times as to the pricing of foodstuffs, impacting the relationship between the municipal government and the cooperatives of farmers. In general, there is no communication between the two main public sectors involved in the implementation of PNAE. By the family organizations, the formation of a central cooperative allowed greater representation of individual cooperatives. As inducing factors for the adoption of innovative practices, we highlight the own federal regulation - which gave rise to the need for inclusion of cooperatives in school food - and social pressure held in the spaces created through discussion forums and public hearings. Among the main barriers, were identified the legacy of past practices resulting from the outsourcing process, the lack of social control and lack of participation by the Council of School Feeding (CAE), besides the lack of public infrastructure geared specifically to meet agricultural and supply issues in the municipality.

This study examines the career of Federal Police special agents in São Paulo, in order to observe how concepts like masculinity, gender and difference are articulated to professionalism by them. This study conceives gender as something that is constructed, and often reproduced when such agents experiences the profession. Thus, it is necessary to explore the existence of an institutional hegemonic masculinity, as female and male, gender are made and how the pattern of heteronormativity are experienced in every day pratice in this career. The field research was conducted in the city of São Paulo. The methodology is based on qualitative interviews and analysis of documents from the Federal Police, as well as statistical data of the gender composition of the group, these empirical evidences are focused by the approaches of sociology of professions.

The goal of this dissertation is to discuss the two main theoretical sources that Jürgen Habermas uses in his essay "Work and Interaction": the Hegel s philosophy of Spirit of Jena period (1804-1806) and the Marx s theory, especially the labor category. In this sense, beyond criticism resumption of primary sources, the study also presents alternative perspectives to those assumed by Habermas in his youth period, mainly in the 1960s. Therefore, a critique of young Habermas' theory becomes possible, from the central concept of the public sphere to the reasoning of cultural formation in the private sphere, this being the focal point of the essay in question.

Tumor spreading occurs mainly by two pathways: through blood vessels and by lymphatic vessels, but the last is preferred by breast tumor cells. Some proteins are involved in cell adhesion and proteolysis, causing metastasis, such as ADAMs, a family of multi-domain and multi- functional proteins that contribute in these processes. ADAM9, a member of this family, has been increased in a large number of human carcinomas, including, breast cancer. In this context, the aim of this study was to evaluate the role of ADAM9 in tumor spreading via blood and lymphatic systems, in the search for new targets and focusing the development of new therapeutical tools. Therefore, MDA-MB-231 breast tumor cells were silenced for ADAM9 and tested with respect to their adhesive and invasive activity against blood and lymphatic endothelium. Our results showed that ADAM9 silencing in MDA-MB-231 breast cancer cells inhibited the invasion of this cells in matrigel (71.51 ± 8.02%) when compared to control cells, without affecting cell adhesion, proliferation, migration, and gene expression of the ADAM10, ADAM12, ADAM-17, cMyc, MMP9, VEGF-A, VEGF-C, Osteopontin and Collagen XVII, however, there was a decrease in the expression of the ADAM15 and increased expression of MMP2 when compared to controls. Furthermore, ADAM9 silencing did not affect the adhesion under flow to these vascular endothelial cells (HMEC-1 and HUVEC) and lymphatic (HMVEC-dLyNeo-Der). However, there was a decrease in the rate of trans-endothelial migration through the monolayer endothelial cells (HUVEC, HMEC-1 and HMVEC-dLyNeo-Der) by approximately 50%, 40% and 32%, respectively. In conclusion, ADAM9 showed to be essential in invasion and extravasation of MDA-MB-231 breast cancer cells through the blood and lymphatic vessels in vitro.

The Steam reforming of Acetone (SRA) reaction was studied on magnesium aluminate (MgAl2O4) supported nickel (Ni) and cobalt (Co) catalysts. The catalysts with 8 wt.% of Ni, Co or Ni-Co were prepared by dry impregnation and characterized with X-Ray Diffraction (XRD), Temperature Programmed Reduction (TPR) and Thermogravimetric Analysis (TGA). The catalytic tests were carried out at the molar ratio H2O/C3H6O = 6 of three ways: i) Thermal decomposition of C3H6O as a function of temperature between 523 and 973K; ii) SRA reaction as a function of temperature between 523 and 873K; and iii) SRA reaction in presence of H2 as a function of temperature. The stability tests were carried out for 4 hours at 773 and 4 hours at 873K. The thermal decomposition of acetone in homogeneous phase was significant above 923K. The SRA on reduced catalysts occur at temperatures above 773K, with conversion in a mixture of H2, CO2, CO and minor conversion to CH4 and C2H4. On Cocontaining catalysts, the SRA occurs via pyrolytic mechanism with the activation of C3H6O by cleavage of C-H bonds, followed of C-C and C-O bonds and oxidation of C formed by H2O. The Ni-containing catalyst, in the presence of H2, is active at lower temperatures (523K) than Co-containing catalysts with conversion predominantly to CH4. The results indicate that the H2 instead of C3H6O reduce of NiO on surface and the intermediates of acetone activation on reduce Ni surface is hydrogenate to CH4 at low temperatures. The thermogravimetric analysis of used catalysts demonstrate greater carbon accumulation on Ni than on Co-containing catalysts.

Within the thematic tourism and libraries the work here presented aims to analyze two public libraries located in Sorocaba(SP), taking in consideration characteristics such as book collection and architecture, and the diversity of the events that take place in these public libraries looking for state their turistic potencial. This work intends as general purpose to enable two libraries of the city of Sorocaba to become a turistic atraction that can be able to be a form of representation and dissemination of culture in the city. After a comparative between the libraries in the city, the two libraries that were chosen are the Municipal Public Library Jorge Guilherme Senger and the Children’s Library Renato Sêneca de Sá Fleury. From the analisys result it was proposed a cultural tour that can be offered in partnership with various entities in the city, acting as a final result of the present work and aiming to offer a cultural tourism proposal in the city to contribute to offer a diverse proposal and to include the local community.

The thesis contains a study on the School in MST Camp: Institutionalization and Management of State Itinerant School Carlos Marighella. The problem of this study lies in the way of managing the traveling school in the MST camp, the contradiction is present with regard to the class struggle and interests defending, as Brazil is, par excellence, the land of large estates and, he, a deep social inequality in rural and urban areas, that can be characterized as social apartheid. In this regard, it is noteworthy that the construction of the Itinerant School has history and school history in the MST has the story of the struggle for agrarian reform. In these struggles, the Paraná bears the mark of the explosion of class struggle in the countryside, whose centrality is in the mechanization of agriculture, land concentration and construction of dams in Santiago Jump and Itaipu, which displaced more than 3,000 families from their land. In the struggle for land, northwest region of Paraná brings the land occupation and school occupation as dispute space. There is, in this struggle, the occupation of Fazenda Santa Filomena, in Planaltina of Paraná, and with it the construction of Camp Elias Gonçalves de Meura. This camp was built Itinerant School Marighella Carlos, who was born as a public school in 2004, which started teaching activities in a stable. Therefore, our purpose was to this school, meet its internal structure and forms of management. So our object is the school management. So we ask ourselves: How is the management of a school of MST in the capitalist state structure? There is an autonomous management from the State? Management mechanisms that are present in the Itinerant School? Collegiate bodies that are present in the school structure? How is the social control of the Itinerant School? In this sense, the school management is the MST or no state control over school management? Given these issues, our intention was to investigate the School Itinerant Carlos Marighella both the organizational aspects, the management, the administrative, educational and financial dimensions, from 2004 to 2013. Therefore, we undertook a bibliographic nature of research and interviews. In literature, the empirical sources consulted were the texts and MST works on education, and the documents produced by the MEC, SEED and State Councils of Education relevant to Education Field and Itinerant Schools. Besides these, we also drew the texts produced by several researchers who analyzed the Itinerant Schools in the different aspects of studies. Interviews were conducted with members of the MST Education Sector, educators and students of EI, public officials and school community camping. The reflections on the school management, despite being a singularity as pedógica experience, to be tensioned by the conflict of land, EI is not the government school, nor he directed. She is the dual management, but brings in your organization elements of the socialist school of work as selforganization in the training process. This is the meaning of this research thesis answered.

In this Thesis we study in details one of the most astonishing application of quantum mechanics which totally departs from our common sense: quantum teleportation in continuous variables. We present a review of the postulates of quantum mechanics and quantum optics systems, in particular for Gaussian systems. After this review we apply these postulates in order to present one of the most counter intuitive applications of quantum mechanics, namely, the quantum teleportation protocol. We study in detail this protocol and we propose modifications in its construction aiming at an improvement in its efficiency. These modifications were made in order to take into account the realistic situations encountered in the implementation of the protocol, i.e., the fact that the entanglement, between Alice and Bob, is never perfect and the fact that states teleported by Alice are near the vacuum state. After this analysis we performed an extension of the teleportation protocol by proposing a multi-channel protocol and studied the case of two channels in parallel. Finally, we created the first quantum cryptography protocol that uses the continuous variables teleportation protocol in an active way. We showed that this protocol is robust to the beam splitter attack and that this protocol is the only one working with direct reconciliation and without post-selection over the 50% loss scenario.

The need for satisfying deadlines and reducing costs made construction companies invest in the improvement of productivity throughout the steps of constructing buildings. This study aimed to stratify the workforce‟s productivity in employment categories during the execution of the plaster coating, showing productivity indicators values expressed in man-hours per square meter (Hh/m²) of executed coating so as to identify among the workforce‟s employment categories chances of improvement. As research strategy, it was used the field survey in five construction works with different types of buildings, where it was made a hard observation and labor productivity collection taking into account the occupation categories (Direct Work, Delays, Mobilization, Downtime, Displacements and Support) resulting in productivity indicators stratified in accordance to these categories. It was diagnosed that the values of the overall workforce‟s productivity ranged between 0.16 and 0.50 Hh/m², considering that the main value in the distribution of its fractions was in the occupation category of Direct Work, which ranged between 0.08 Hh/m² and 0.23 Hh/m² regarding the other categories. The higher the representativeness of main productive and auxiliaries categories (Direct Work, Support and Mobilization) over the categories associated with the unproductive activities (Downtime and Delay), the better the productivity detected, although strong statistical correlation was not observed. Regarding the category Direct Work, the best productivity of labor is achieved in the implementation of the coating on the ceiling over the implementation on the walls. Thereby, this work‟s main contribution is in the preparation of the analytical structure of occupation categories to the plaster coating department as well as the unfolding of workforce‟s productivity indicators in these categories for this department.
