Among the probable carbon sources, there are the polymers, as the phenolic resin, which produces residual carbon around 60% wt./wt. after thermal treatment. It is classified as non-graphitizable, because it has not graphitic lamellaes until temperatures between 2600°C and 3000°C. To organize carbon in temperatures around 1000°C, the catalytic graphitization was suggested, where the phenolic resin receives metallic and/or inorganic agents. Thus, three resins received the agents (ferrocene, boric acid and exfoliated graphite) and they were compared, in specific conditions of processing, to induce turbostratic or graphitic structures. Turbostratic structures have organization beyond 1 nm and graphitic fragments or graphene sheets stacked in almost parallel organizations. Graphitic structures have parallel sheets stacked. Phenolic resins with any graphitic organization would be useful in refractories or for technological applications, depending on the agents used for this induction. Materials with higher lamellae organization could reduce production costs, polydispersivity and increase their efficiency. The study was divided in three stages. In the first stage, some of the proposed procedures proved viability to this route. The best results of the organization level were between 58 and 61% and were obtained for the ferrocene agent, with thermal treatment with more isothermic steps until 1000°C/5h. After the second treatment, until 1400°C/5h, were between 60 and 65%. In the second stage was evaluated the mixing procedure in the carbon organization, the higher organization (70%) was inducted with laboratory stirrer and ultrasonic mixer, with the synthesized modified-novolak resin and ferrocene. In the third stage, the systematically evaluating the thermal decomposition of ferrocene showed phases with carbon (amorphous, turbostratic and graphitic) and with iron (hematite, maghemite, cementite and gamma-iron) and structures type hollow-like onion carbon with magnetic properties were obtained. The results open new possibilites of applications in materials engineering.

Forecasting financial losses and making decisions to avoid or reduce them has been a challenge for every investor. On one hand, due to the availability of data and its simple implementation, technical analysis methods have been quickly gaining supporters. On the other hand, modern computers processing power together with advances in text mining provides the opportunity to explore the investor’s behaviors in new data types: textual. This research evaluates the relationship between the Brazilian stock market and news published on national midia, focusing on automatic search for patterns related to down movements using machine learning algorithms. Six experiments were performed to analyze the possibility of predicting price falls automatically, followed by case studies in the search of explanations from the classifiers that justify the predictions.The results show that text mining based approaches overcome traditional strategies when forecasting losses, but the underlying patterns understanding is limited due to the complexity of the classifiers and high dimensional vocabulary.

This study is an attempt to understand the importance of developing a typology within the moral reflections proposed by Nietzsche. We understand that typological analysis is primarily a way of moving away from metaphysical thinking, as well as from an absolute generalization of concepts and values held by universals. Moreover, moral types are, we believe, in line with the Nietzschean view of reality, which is characterized by a plurality of meanings and values, which are embedded in a constant becoming and do not allow the existence of the axiological and conceptual crystallization desired by metaphysics. This view fits in with the Nietzschean concepts of will to power and perspectivism that we believe are fundamental to understanding why Nietzsche points to the need to erect a moral typology. Finally, we must think of moral typology as the product of genealogical research. It is from moral genealogy that we gain insight into values and morals through their importance or harm to life. Types in this context are expressions of a certain form of life, whether ascending or degenerate.

During the last decades, several studies point for a new Society shaped and framed through the optical of a digital culture. New devices emerge in a high speed, precluding the updating of the most adventurers. In front of this apparent digital society, new languages, symbols and signs receive several configurations. Because of it, the inclusion as the exclusion is present. For this new configuration of idealized society, the digital devices make a part of the everyday life as sensory extension of the human being. One of the problematics from the digital culture is the exacerbated spread of information, between real and true, and how to change them, once they digress and dominate the minds, especially of the youngers, about knowledge. Would the public school be included or excluded of this new device? In front of this, the present search aimed understanding how and if it happens, in the public-school group of São Paulo state, specifically in the elementary school, the teaching of subjects trough the digital technologies. The study showed as the general objective map, if the Science teaching should be effectively through the digital technologies. Besides the general objective, four specified objectives were created, like: analyze laws, provisional measures, decrees and other official documents of state bodies that legislate about education in Brazil, mainly the Federal Government, about the guidelines for the Science and technology teaching; catalogue schools to map and analyze which the researches, of infrastructure, human and economic are reserved for the process of the teaching through the digital technologies, confer and describe if in the elected institutions put or are putting some public program about incentive or broked teaching, as the teachers involved in the process, their abilities, knowledge and formations to teach their subjects, characterize what is the students vision about the learning through the digital technologies, and understand what they think about the broked process and about the subjects. Besides, what is the proportion that these technologies take in their lifes as confering their knowledges and abilities about them. Analyzing the search fulcrum, the methodologic triangulation was realized through the interview with three different groups: a. students of elementary school; b. teachers of public schools; c. manager- teacher that knows about the Federal Government jobs about digital technologies at school. So, qualitative and quantitative analyses were done during the purposed study. The analyses point that there is a strong speech that, for conception, treats the children and adolescents as native digitals in a slant of knowledge about digital technologies. But, these knowledges are in the most about games and social groups, besides entertainment things, so, it’s not real. About the teachers, the search shows they frequently confuse the meanings about the broking through digital technologies, and those that searches a broked process, what they do only, once that we conclude school is suboptimal about digital culture. Finishing, the study points there is a big abyss among what the Federal Government speaks, its actions and the effective inclusion of the public schools in digital culture. Besides important questions that involve the digital Technologies in a social and historic slant, that aren’t worked. We conclude the possibilities of field studies STS need to be discussed as a way for inclusion of the school technologies, since the basic education.

In this study, we problematize the invisibility of children's occupations, with an emphasis on Early Childhood Education. The general objective was to describe and analyze the education of children from an occupational perspective. The specific objectives were: a) To describe the activities, routines and environments of Early Childhood Education from an occupational perspective; b) To understand and analyze how children with typical and atypical development become involved in the activities, routines and environments of Early Childhood Education; and c) To identify and analyze the implications for Occupational Therapy in order to promote the participation of children in Early Childhood Education, from an occupational perspective. It was na empirical, qualitative, descriptive and exploratory research. The study participants were: four children with typical development; four children targeted by special education, three with Autism Spectrum Disorders and one with physical disability due to congenital malformation; four pre-school teachers and one trainee that accompany one of the children. Data collection was performed from direct observation according to the narrative descriptions technique. In addition, semi-structured interviews were conducted with the teachers and the trainee. The content analysis technique guided the data analysis. We found three categories of analysis: 1) Environments, routines and activities of early childhood education, which brings together results related to environments as promoters or inhibitors of participation in early childhood education, as well as analyzing the learning opportunities present in school routines, grouping the activities of early childhood education around three axes. : play, self-care and formal learning activities; 2) Participation of children with typical development and PAEE children in the environments, routines and activities of early childhood education, which presents and discusses results regarding the participation profiles in the three axes of early childhood activities found in the study, among which children with typical development predominantly demonstrated full participation and PAEE children demonstrated participation ranging from full, active assisted participation to restricted participation; and 3) Uncovering spaces for Occupational Therapy in Early Childhood Education from an occupational perspective, a category that analyzes gaps found in the results that allow contributions from Occupational Therapy to the context of Early Childhood Education. The defense for the understanding of Early Childhood Education from an occupational perspective contemplates the comprehension of the school occupations of play, self-care and learning of formal contents. Children with typical development show full participation in these occupations. Special Education Target Children, especially those who manifest Autism Spectrum Disorders, have restricted participation and require mediation. The specificity of the occupational therapist is to develop strategies to promote the full participation of all children in these occupations

In this work, we study existence and multiplicity of weak solutions for three problems involving fractional operators, with emphasis on critical growth nonlinearities. The first problem deals with the existence of sign-changing solution for an equation involving the fractional Laplacian and fractional critical Sobolev exponents. In the second problem, we study the existence of signed and sign-changing solutions for an equation involving the fractional p-Laplacian with a Kirchhoff term and fractional subcritical and critical Hardy-Sobolev exponent. The last problem approaches existence and multiplicity of positive solutions for an equation involving the fractional p-Laplacian with a Kirchhoff term, fractional subcritical and critical Hardy-Sobolev exponent and weight with indefinite signal. The presence of critical exponents generates additional mathematical dificulties in obtaining solutions due to lack of compactness of the Sobolev embedding. In our studies, we used variational methods such as the Mountain Pass Theorem, constraint minimization on Nehari sets and the fibering method.

Alternative Communication means and strategies are useful tools so that students with non-verbal disabilities to socialize in different environments. This research has objective to elaborate, implement and evaluate a program of formation of communication partners in the community for non-verbal users of alternative communication with autism. The specific objectives were: a) form communication partners to interact with users of Alternative Communication; and b) to evaluate the effects of the implementation of the Alternative Communication Program with users with autism in different environments and with different interlocutors. The study included four participants with autism, four family participants and four participants from the community. Data were collected in a medium-sized municipality and another small municipality, both located in the state of São Paulo in several environments frequented by participants with autism, such as their residence and general trade. A intermittent multiple baseline design cross subjects and environments was used in this research. Eight instruments were used to collect the data: 1) semi-structured interview script for parents / family; 2) a semi-structured interview script for the communication partners; 3) list of participants' interests with autism; 4) daily observation protocol; 5) post intervention questionnaire on the use of alternative communication for the communications partners ; 6) protocol of registration of the social interaction of CA users with community communication partners;7) protocol recording the interaction of community communications partners with CA users; and 8) social validity questionnaire. Communication partners training was the first step of research data collection of the research in which the teaching procedures were implemented with the users with TEA, at which point these procedures were filmed for further analysis. Participants with autism underwent initial assessments, corresponding to baseline sessions, and then intervention was initiated, after baseline stability check. All sessions were performed within the routine in which the participant is inserted. After 13 months of application of the program, a questionnaire was collected with the communication partners, in order to observe if CA users acquired communicative skills in the different environments after using the alternative communication, as well as to help them to expand the alternative communication program at home. The results show that from the training program with the community communication partners with the CA users participants demostrated satisfactory development and their communication skills improved with different people, according to their needs and the number of communication partners has been increased.

This thesis intends to contribute to the ethnography of the peoples of the eastern tukanoan linguistic family on the Uaupés river (specifically, Tukano and Desana), focusing in particular on the low course of this river, where there is a markedly dispersed set of multiethnic communities. We intend to highlight a relatively unexplored aspect of Uaupesian sociality in the available literature, namely, the attributes and principles of socio-spatial dynamics that involve groups at different scales in a seemingly continuous movement along the upstream-downstream axis. It was possible to map, mainly, from the memory of some residents of the lower Uaupés, a series of movements downstream, as well as their distinct contemporary and past motivations. In general, the thesis contributes to the discussion about the formation of groups and persons from the trajectories and displacements interviewed in the way such interlocutors conceptualize their arrival and permanence in the low Uaupés. In the thesis some classic themes of South American ethnology and the Upper Rio Negro are taken up such as hierarchy, naming and shamanism.

Following the information obtained by a rational design study, cyclic and dimeric helical stabilized analogues of the peptide Cm-p5 were synthetized. The cyclic monomer showed an increased activity in vitro against Candida albicans and Candida parapsilosis, compared to Cm-p5. Initially, fourteen mutants of Cm-p5 were synthesized following a rational design to improve the antifungal activity and pharmacological properties. Antimicrobial testing showed that the activity was lost in every of these fourteen analogues, suggesting as a main conclusion, that a Glu-His salt bridge could stabilize Cm-p5 helical conformation during the interaction with the plasma membrane. A derivative, obtained by substitution of Glu and His for Cys, was synthesized and oxidized with the generation of a cyclic monomer with improved antifungal activity. In addition, two dimers were generated during the oxidation procedure, a parallel and anti-parallel one. The dimers showed a helical secondary structure in water, whereas the cyclic monomer only showed this conformation in SDS. In addition, the antiparallel dimer showed a moderate activity against Pseudomonas aeruginosa and a significant activity against Listeria monocytogenes. Nor the cyclic monomer nor the dimers were toxi c against macrophages or THP-1 human cells. Continuing with the covalent modifications of the Cm-p5 structure, in chapter 2 is described the design, synthesis and characterization of 15 lipidated and cyclo-lipidated analogues of Cmp5. Previous studies showed that N-lipidation of Cm-p5 by Ugi-4CR increase notably the antifungal activity. Our initial biological test showed that lipidation with decanoic acid did not display any effect inthe activity of Cm-p5, while pentadecanoic acid decreased it. These results are not in accord with the increased activity in case of the Ugi lipidated analogue. The Ugi-4CRdo not only introduces a lipid chain, also produce N-substitution that can alter the conformational behavior of the lipid chain. To determine the influence of N-substitution, three analogues containing Ala, Gly or Pro between the lipid chain and the normal sequence of Cmp5 was synthetized. Gly and Pro are implied in several conformational changes in proteins or peptides.Gly possesses high flexibility while Pro is the only N-alkylated aminoacid and participate in loop or rigid structure formation. In addition, following the expected increase of activity by disulfide bridge formation, similar variants possessing Ala (introduced as a comparison), Gly or Pro between adodecyl chain and cyclic/dimeric CysCysCm-p5 were XVII prepared. Finally, lipidationby Ugi-4CR with n-dodecylisonitrile and subsequent cyclization between Cys produce cyclic and dimeric versions of Ugi lipidated cyclopeptides. All compoundsare under biological evaluation thatwill permit to gainconclusion about the structural motif needed to produce the more antifungal cyclic and lipidated analogue of Cm-p5. In chapter 3, we used the combination of solid phase and liquid phase methods for the synthesis of the anticancer drug, carfilzomib (CFZ). The convergent route comprises the tetrapeptide construction in solid phase followed by coupling with the previously prepared Leu-epoxide. Side effects of CFZ include the heart failure and shortness of breath so that the development of bioconjugation for targeted delivery is desired. With this aim, we prepared a traceless carbonylacrylic-Val-Cit-PAB linker as an alcohol in solid phase using the special DHP resin in high yield. This alcohol linker was tosylated and iodinated with the aim of improve the yields of the substitution reaction with CFZ (substitution of tosylate need heating). The pH (low) insertion peptides (pHLIPs) target acidity at the surfaces of cancer cells and show utility in a wide range of applications, including tumor imaging and intracellular delivery of therapeutic agents. We pretend to merge the capacity of tumor cell selectivity of pHLIP peptide with the traceless, stability and selective delivery of the new carbonylacrylic linker. Finally, the bioconjugation of CFZ to pHLIP peptide through the carbonylacrylic-Val-Cit-PAB linker, for the traceless release and targeted delivery to tumors could significantly improve the effectiveness of this drug in cancer treatment.

The soybean plant (Glycine max L. Merryl) produces a range of flavonoids as secondary metabolites, known to cause damage to herbivorous insects. However, Spodoptera frugiperda and Anticarsia gemmatalis (Lepidoptera: Noctuidae) can feed on soybean leaves, causing great losses in Brazilian crops. Surprisingly, little is known about how these insects metabolize soybean flavonoids, and how their metabolism explains their status as agricultural pests. Therefore, the present work aims to evaluate the toxicity of model flavonoids quercetin and rutin in the development of S. frugiperda and A. gemmatalis, in addition to elucidate the metabolic strategies used by these insects to deal with flavonoid toxicity. The insects were reared in artificial diets containing quercetin and rutin. Larval weights, larval stage durations, and mortality were followed during the experiments. Feces samples from caterpillars were analyzed by LC-MS to identify metabolites from quercetin and rutin, as well as naringenin. In vitro enzymatic assays with insect midgut tissue using quercetin and rutin together with UDP-glucose were performed in order to confirm the production of glucosylated metabolites found in feces. Quercetin and rutin showed toxicity in the diet, resulting in lower larval weights and longer larval stages for both insect species. Glucosylated, methylated, and sulfonated derivatives were detected in feces extracts, as well as di- and tri-glucosides and combinations of these functionalizations, including different regioisomers. S. frugiperda also produced phosphorylated metabolites of quercetin and naringenin. Both species are able to metabolize quercetin, rutin and naringenin, generating potentially less toxic compounds. Some glycosides were also observed in enzymatic assays, confirming the activity of UDP-glucosyltransferases in flavonoid metabolism. The experiments presented here provide qualitative data about the biochemical reactions employed by S. frugiperda and A. gemmatalis in flavonoid metabolism and contribute to future studies on their interactions with chemically defended host-plants.

Due to the high demand for software as a service, more and more companies are forced to modernize their applications to the digital world. However, this modernization needs to be very well designed to be able to follow the customers needs and also to have low operation cost, especially in applications that have a great deal of functionality variability for their customers. In this context, one of the faced problems is related to the management of multiple versions of ``similar'' systems and software evolution. To solve this issue, the SPL approach is used, while the Micro Services architectural style is a way to make the evolution process lighter, since it can be performed only in the specific micro-services being updated. However, despite being an important subject and widely used by the software industry, in the academy we did not find a large number of papers dealing with micro services and SPL. In the survey carried out in this work, only two papers were found that used micro services and SPL, one of them directly related to this work, applying the micro-services architecture and a SPL process, and the other work which used micro services and SPL to improve the flexibility of product family variability. However, the articles briefly discuss the process of how services were designed, and so this point needs more research. In addition, the main focus of the evaluation was on maintenance tasks, not evolution, as we investigated in this research. Therefore, this work aims to evaluate the evolution (both in the addition of new features and in the maintenance of existing features) of a SPL through the use of micro services in order to be able to affirm if the impact of micro services really improved the task of evolution. In order to reach the expected objective, this work had the partnership of a company based in Rio Grande do Sul, which has a ERP in its product portfolio, implemented as a product line. Based on this, a case study was carried out in two scenarios (one with micro services and the other without micro services), which allowed us to evaluate that the use of micro services brings great benefits in the evolution of a software product line, mainly in adaptive maintenance tasks. Finally, in addition to evaluating the impact of the use of micro services in the evolution of a product line, this work contributes with the lessons learned from the migration of a project developed in the traditional approach to the use of micro services, using data from a real experiment with focus on software engineering.

The present study had as object of study the teaching of Nature Science teachers from São Paulo state public school, located in the Sorocaba Teaching Board, within the limits and possibilities of the pedagogical practice in its relation with different praxiological nuances. It aimed to investigate the praxis developed by these teachers, articulating them in the Marxist praxic dimensions. The theoretical framework permeated three authors who conceptualized praxis in Marx's concept: Vázquez who conceptualized praxis as conscious and oriented human activity; Lefebvre who brings to praxis the refinement of his subjectivities in reproductive, mimetic and transformative dimensions, and Freire, who understands the educational process as transformative, inherent in an authentic praxis. The data obtained were verified through a qualitative approach, in a group of 10 participating teachers. In this sample universe, structured interviews and classroom observation were conducted. For data capture and analysis of results, the following praxiological structures (subject, context, process) were defined as beacon parameters, which within the research methodological dynamics emerged and revealed the proximity of the praxis dimensions of the sample group. In the end, the research brings denunciation and announcement, in Freire. Denunciation of the empirical epistemic focus that limits the teacher in the dialectic of his praxis. Announcement, by overcoming methodical scientific teaching, by a praxiological epistemic scientific teaching, within the framework of an authentic educational practice. Hence the need to implement transformative praxiological processes in the permanent formation of teachers, through the establishment of partnerships with educational public agencies.

Regarding dramatic depersonalization as a composition procedure which overlaps the traditional concepts of lyrical self and authorship, I chose examine some formal levels of the paradox and contradiction in ortonymic and heteronymic thought in Fernando Pessoa’s work. First, as the depersonalization of the lyrical self, theorized by the poet, appears in the dramatic form of the poem The Sailor delimiting formal stages of writing and composition to be achieved and overcome by heteronyms. Following the path of depersonalization opened by the poem The Sailor, I will try to show how Alberto Caeiro, Ricardo Reis, Álvaro de Campos and Fernando Pessoa ortonym bring Pessoa’s depersonalization theory to the last consequences, disfiguring and reconfiguring fragments of reflective notions around the clash between identity of the lyrical self and the non-identity of the dramatic self. The formalization of the gap between them will be dealt with overall by the opposition between Caeiro’s sensible certainty and Campos self-reflective sensation, opposition that constitutes one of the propelling elements of depersonalization in heteronyms. Alberto Caeiro’s sense-certainty engages itself in undoing the ontological self-certainty as the foundation of heteronymic cogito. The idea is that by formalizing the poetic word with the objective experience, the master heteronym claims for himself and his disciples the truth of sense-certainty against the tyranny of representation. Afterwards, I will show how Álvaro de Campos, Fernando Pessoa ortonym and Ricardo Reis, while treading the path of depersonalization opened by the cunning of Alberto Caeiro, condenses fragments of reflective notions of the subject as propelling element of heteronymic depersonalization.

Regarding ethnodevelopment initiatives with traditional communities, indigenous peoples occupy a recognized space within public policies. In the context of family farming, in which indigenous people are beneficiaries by law, a set of rural extension actions is developed in the State of São Paulo based on the State Program for Sustainable Rural Development (PDRS): Microbasins II, Market Access, which contemplates the "Strategy of Participation of Indigenous Populations." In this context, the objective of the research was to evaluate the conceptions, ways of implementation, the perceptions and social, cultural and environmental impacts of the activities of this program in Aldeia Boa Vista and Aldeia Itaoca Tupi, where agroforestry and rural tourism systems were implemented, respectively.The methodological orientations involved bibliographic and documentary survey and case study.It was noted that the changes of government directly affect the actions of public rural extension mainly impacting family farming. Indigenous peoples are even more disadvantaged because they do not have However, agroecology as well as the education and formation of socio-technical networks have proved to be positive instruments to overcome the challenges related to interculturalism faced by extensionists in the field. Bureaucratic obstacles were the biggest difficulties for the implementation of the Program. However, the final assessment is positive: there have been advances in ATER services provided to indigenous communities in the state of São Paulo and the initiatives have created references that can guide the creation and / or improvement of policies aimed at strengthening and emancipating indigenous people in the environment rural.

The objective of this study is to understand how the school reform project “Reorganization” of 2015 reproduces socio-spatial inequality in Sorocaba-SP, more specifically around a school in the outskirts of the city. With this initial objective in mind, we have made a diagnosis based on the relationship between school management and urbanization. The research cut took into account Henri Lefebvre´s theory of space production and had the contribution of the most diverse authors from the most varied areas of the Social Sciences to the accomplishment of a robust analysis of the events in that period. The historical recovery of the constitution of schooling and urbanization was important for the formulation of genetic movements that culminated in the occupation of school project that produced and reproduces the current reforms. We understand that this whole process is part of a totalization in the space convergence of the school bureaucracy to the founding elements of urbanization, which reveals the modus operandi expressed in modernity, its unfinished “emancipatory project”. The results of the survey show Sorocaba that pushes public education apparatus into regions of social vulnerability, or that produces “sanitized islands”, closing schools in its expanded center. The “Veiled Reorganization” occurs discreetly and areas of real estate speculation are amortized, in a attempt of property valuation. A school in the northwest of the city was used as the locus of the study, and the concreteness of the main concepts: democratic management; urbanization and the world of life are exposed throughout the text as way of expressing the vicissitudes of the real, but not imposing the phenomenon in a finished form, emphasizing its contribution as a way of understanding that is always constant, and never closed.

Lattes Platform metadata has been used frequently in scientific researches and technical reports from funding agencies, as also in higher education institutions and by private companies, aiming elaboration of Science and Technology indicators. In turn, the synclattes automated tool has been relevant for extracting data from the researchers' Lattes curriculum. In this context, the goal of this project was the development of an interactive interface for the visualization of scientific production indicators by use of the synclattes. It is a research of applied and exploratory nature, having as case unit the Federal University of São Carlos – UFSCar. Based on the concepts of information visualization area, a system was developed for the visual representation of data bibliometric, containing several graphs such as bars, stacked bars, tag cloud, graph and matrix of collaboration. Therefore, through a relevant data source such as the Lattes Platform, it was possible to elaborate a study about UFSCar's scientific production, considering the 50 researchers who more produce articles in events and in journals. Furthermore, this scientific work showed the viability of implementing an interactive interface for the visualization of Brazilian’s Institutes of Science and Technology bibliometric indicators, from data extracted by the synclattes.

The aim of this work was to look at the conflicts of a street theatre ensemble based in Sorocaba. Away from São Paulo, the ensemble did not go through the marketing's pressures of the capital and persevered over the sixteen years of existence. The cornerstones of this study are the moment which the ensemble was stablished, the organisational and contextual necessity of Sorocaba, the city’s public politics of cultural fundings, the ensemble's militancy and theatre pedagogy. Due to my immersion in this work, I came across protocols, reviews and clippings. Furthermore, it enables me to identify a curios core element for the survival of the theatre ensemble, in its own purpose for “theatre’s Decentralisation and popularisation”. The ensemble’s engagement to create an identity generated the elaboration of a examination, which even in the challenging and substandard moments, made it possible to recover and alter their work. Consequently, contributing to their permanence. This research was done based on interviews, essays, my daily participation within the ensemble and other documents; which suddenly brought the aspects that composes the existence of the street theatre ensemble. Looking globally at the proposed research, it becomes singular the Study Case in Nativos Terra Rasgada ensemble, using a Qualitative Methodology.

Xylella fastidiosa (XF) is a bacterium capable of colonizing a large number of plants, but is mainly known to cause disease in economically important crops such as citrus, grapevines, coffee and more recently olive trees. XF colonizes the xylem vessels, forming biofilm and thus blocking the passage of sap and water from roots to leaves. General symptoms related to diseases caused by these bacteria are leaves wilt, burning and subsequent leaf necrosis, leaves chlorosis and in same pathosystem plant death. The bacterium, which until recently was restricted to the American continent, in 2013 was reported in southeast Italy causing severe symptoms in olive trees leaving to dead of over one milion plants and infected eleven million. This desease was call as Olive Quick Decline Syndrome (OQDS). Since then XF has also been reported in other European countries, such as France, Spain and Portugal, infecting sweet cherry, almond, lavender and ornamental plants. Lately, in mid-2016, similar symptoms as observed in disease olive plants in Italy were also found in olive plants in the state of Minas Gerais in Brazil. The identification of XF in symptomatic olive trees in Brazil leave us to some questions about the; geographic distribution of infected plants, genetic diversity of pathogen, and natural infectivity of possible vectors involved on natural transmission. Therefore, the objetives of this work were; 1. to analyze the distribution of XF in olive orchards in southeastern Brazil; 2. to determined the genetic diversity of strains isolated from symptomatic trees; 3. to verify the natural infectivity of possible vectors. Targeting the objectives 1 and 2 aproximatley 500 samples with OQDS-like symptoms were analized for the presence of XF by using specific primers and bacterial isolation in agar medium growth following the genetic diversity studies. Those samples were sampled from twenty-five orchards located in 15 cities of states of São Paulo and Minas Gerais plus one from Espirito Santo. XF was identified in 21 of the 26 orchards analyzed. A total of 204 isolates were cultured from the symptomatic samples. Twenty-one representative strains of whole population were typed by both Multilocus Sequence type (MLST) and Simple Sequence Reapts (SSR) and the total population by the last methodology. Sixty-five percent of strains were identified as ST16 (previsouly reported in coffee plants) but others already described such as ST70 (from in hibiscus) and ST13 (from citrus) were found causing OQDS in olive plants. Beside these, new STs like the 84, 85 and 86, all belonging to subsp. pauca of X. fastidiosa were also identified in disease olive plants. Population genetic analysis using twelve SSR markers clustered the total population (204 strains) from 16 different orchards representing 12 different municipalities in only three subpopulations. Except the strains from SPA1, MG18, MGA7, MG10 and MGA4 all the remaining strains were placed in a specific subpopulation. In the SPA1 (S22°42'10.71"/W45°41'32.91") was found the largest number of private alleles and heterozygosis and also two different STs (84 and 86). The unbiased heterozygosity (HNei), ranged from 0 to 0.53 (Avg 0.20). Analyzes of possible migration routes have shown the orchards MG-A1 and MG-A2 as the largest migrant donors. X. fastidiosa was detected in at least 37% of potential vectors in commercial orchard SP-A1.

Internet and social Web made possible the acquisition of information to feed a growing number of Machine Learning applications and, in addition, brought light to the use of crowdsourcing approaches, commonly applied to problems that are easy for humans but difficult for computers to solve, building the crowd-powered systems. In this work, we consider the issue of semantic drift in a bootstrap learning algorithm and propose the novel idea of a crowd-powered approach to diminish the effects of such issue. To put this idea to test we built a hybrid version of the Coupled Pattern Learner, a bootstrap learning algorithm that extract contextual patterns from an unstructured text, and SSCrowd, a component that allows conversation between learning systems and Web users, in an attempt to actively and autonomously look for human supervision by asking people to take part into the knowledge acquisition process, thus using the intelligence of the crowd to improve the learning capabilities of Coupled Pattern Learner. We take advantage of the ease that humans have to understand language in unstructured text, and we show the results of using a hybrid crowd-powered approach to diminish the effects of semantic drift.

There is a growing interest in metric studies on scientific collaboration in Brazilian postgraduate studies. However, a significant part of these studies are conducted from international bibliographic databases at the macro level, while other studies are limited to a particular Postgraduate Program (PPG), making comparative analysis and group mapping impossible. The general objective of this research comprises the elaboration of indicators on the national and international scientific collaboration of the PPGs of the Applied Social Sciences Area 1 - Information Science, recommended by CAPES of Brazil. The method comprised a quantitative approach of exploratory nature. Bibliometrics and social network analysis were used as analysis techniques. The sample analyzed comprised 519 bibliographic records referring to the scientific production of 421 permanent teachers who work in 27 PPG of the Applied Social Sciences Area 1 - Information Science, from 2013 to 2018. The results achieved included the elaboration of a set of indicators. involving: 1] production characterization by PPG, identifying the evolution and percentage of contribution; 2] identification of national and international scientific collaboration through co-authoring, highlighting initiatives with international institutions, the main vehicles of communication and the most investigated themes. It can be concluded that the results achieved can contribute to the improvement of the PPG and of the National Graduate System, by maximizing the understanding of collaboration in the area of Applied Social Sciences 1 - Information Science, by providing a set of indicators, elaborated from the fusion of metadata from two sources of information. Lattes and Web of Science, enabling the identification of the institutional links of the authors in relation to PPG and international institutions.
