This research proposes an empiric study on the tattoo artification processes and starts with the following question: what are the strategies and discourses developed by male and female tattoo artists for the practice be artified? Since the 1980s and 1990s, in Brazil, tattooing has gone through the processes of professionalization, commercialization, commodification, sanitation, regulation, field standardization and, finally, artification, changing the ways it is conceived socially. Thus, the research aims to understand the power relations and negotiations between male and female tattoo artists regarding the knowledge construction about artification practice in São Paulo. It also seeks to analyze how the association between tattoo and art materialized in the fields of production, mediation and reception; understand the dimensions negotiated by male and female tattooists in order to construct the artistic value of tattoo; and, finally, to reflect how generation, gender, race and class differences reverberate in tattoo artification. These purposes will be achieved through participant observation in the institutions that discuss tattoo as art, semi-structured interviews with male and female tattooists inserted in the process of tattoo artification in São Paulo, bibliographic research and theoretical discussion on body modification and art.

Modern zoos are increasingly participating in the conservation of wild fauna. The squad allows the study of the several variables that make up the environmental, health and animal habits, in addition to the opportunity to obtain rare biological material for the development of new studies. Mammals of the Carnivorous Order are predators present in terrestrial ecosystems, being top animals in the food chain that have great ecological importance. The target species of this work were 3 carnivores belonging to the Felidae Family, genus Leopardus (Leopardus colocolo, Leopardus geoffroyi and Leopardus tigrinus) in which the objective of the present work was to establish hematological and biochemical reference values for small feline species under human care belonging to the squad of the Fundação Parque Zoológico de São Paulo. Through a retrospective study of the results of hematological and biochemical tests, the possibility of determining specific reference values for the species under study was studied, since the values used for these species are outdated and often comes from extrapolation from other species of felines, including domestic cats. For a correct interpretation of blood tests it is necessary to know and use specific reference values for the animal species being studied, adapted to geographical conditions, management, feeding and even the laboratory that performed the hematological analyzes. The results found made it possible to better understand the population of small cats in the FPZSP, in which the focus individuals of the study are mostly elderly, allowing the reference values to be established for this age group of captive cats.

Although the use of antibiotics has been indispensable for the control of diseases in humans and animals, their indiscriminate consumption has favored the appearance of bacteria resistant to antibiotics. A way to tackle this problem is based on the use of natural compounds with antibacterial properties, as an alternative to conventional antibiotics, due to their different mechanisms of action. In this context, this work aimed at the development of electrospun fiber mats of poly lactic acid (PLA) containing natural rubber (NR) and curcumin for applications in bactericidal wound dressings. PLA was chosen as the base polymer for fiber production because it is easily electrospun, besides being biocompatible and biodegradable, while latex (containing NR) was chosen due to its natural stimulus to angiogenesis, biocompatibility, low cost and easy handling. Curcumin was chosen because of their antibacterial, antioxidant, antifungal and anti-inflammatory properties. Due to the incompatibility between the polymers, the NR epoxidation reaction was used to favor the interaction with the PLA. Microfibers from the blend of PLA and NR (without the compatibility process) were also produced with two concentrations of curcumin (2.5% an d 5%, in relation to the polymeric mass), using an asymmetric membrane structure (anisotropic structure composed of 2 layers of fibers with different properties in terms of morphology and properties) aiming at application in wound dressing. The results indicated that the asymmetrical mat containing curcumin showed antibacterial action against S. aureus and E. coli bacteria, with more promising results for the former, according to the results of a wound model using ex-vivo pigskin. The results also showed that the asymmetric membranes were able to prevent the penetration of bacteria for up to 14 days. In addition, photodegradation, one of the main disadvantages of curcumin, was overcome with the addition of an extra top layer of PLA nanofibers over the curcumin-containing PLA/NR microfiber layer, which was able to prevent its photodegradation for up to 12 hours when exposed to light. Finally, the results presented show two different alternatives for obtaining microfibers using the blend of NR and PLA and also the high potential use of curcumin for wound dressing application.

This work presents N-BEATS-RNN, an extended version of an ensemble of deep learning networks for time series forecasting, N-BEATS. We apply a state-of-the-art Neural Architecture Search, based on a fast and efficient weight-sharing search, to solve for an ideal Recurrent Neural Network architecture to be added to N-BEATS. We evaluated the proposed N-BEATS-RNN architecture in the widely-known M4 competition dataset, which contains 100,000 time series from a variety of sources. N-BEATS-RNN achieves comparable results to N-BEATS and the M4 competition winner while employing solely 108 models, as compared to the original 2,160 models employed by N-BEATS, when composing its final ensemble of forecasts. Thus, N-BEATS-RNN's biggest contribution is in its training time reduction, which is in the order of 9 times compared with the original ensembles in N-BEATS.

The dissertation aims to understand the set of interactions established between terreiros and bocas-de-fumo located in the city of Maceió, Alagoas from two relational bundles: ritual and gender stylizations. It is anchored in an ethnography that considers special attention to the space of interlocution between bocas-de-fumo and terreiros as a result of changes in forms of governance over life in the peripheries, as well as the productive technologies generated in terreiros from the incorporation of entities and control of the circulation of information. As a background, changes in the forms of government in the peripheries of Maceio from what locally came to be called the rupture of the alliance between the criminal collectives Primeiro Comando da Capital and Comando Vermelho regarding the production of senses of masculine identification remain in abeyance. In this sense, being ethnographically inspired, it is nourished by the role of encounters and possibilities of interlocution established from the performance of different roles in interpersonal networks. Concerned with following the relational plots elaborated with queers and márginals - the research's interlocutors -, the field of concern gradually changed. In a first moment, the center of the project was to follow the battles of queers through the incorporation of female spirits and their production crossing gender stylizations as dangerous. However, following episodes and narratives involving their friendly relations made it opportune to observe plots involving men in criminal dynamics. In this way, this shift in focus led to an approach with a body of literature gathered among different concerns. More roughly, studies on gender and sexuality in terreiros; forms of government in Brazilian urban peripheries and the dialogue on illicit markets more properly related to drug trafficking. In relation to these different research contexts, the accumulation of works exploring interfaces between gender and sexuality studies and urban peripheries has sensitized the idea of the intersection of an unprecedented field of relations articulating different social landscapes. In this sense, in relation to the context of Alagoas, it is possible to argue that the idea of gender styles and rituals seems to point to how the presence of a patriarchal bias in structures of care and protection - in which the hierarchy in terreiros is situated, is founded through transitional experiences, in which subjects experience a constant immanence. Gender, in this way, articulates itself much more to the idea of an eternal tension and delimitation of another to be fought, than necessarily a stabilization of meaning.

This dissertation aimed to study how the non-nursery Pedagogical Documentation enables the discussion of pedagogical practices with babies, favoring teacher education, considering the action of the teacher who registers and researches through this approach, and the requests, both as actors in the contexts of collective life. At first, it understands the conception of this approach, like the studies carried out by the pedagogies of Northern Italy, in the Region of Emillia Romana, as an instrument for reflection and planning of teaching actions in order to build forced experiences with babies as protagonists, and to support pedagogical practices and professional training. Adopting the techniques of observation, recording, document analysis, study, reflection and sharing with the school community, the Pedagogical Documentation was built, producing the data of this research and implementing its principles as a research method of the practice itself. Pedagogical Documentation as a research, reflection and communication tool can be a new way for the education of children and young children, making the school alive, producing culture, opportunities, which provokes thinking, reveals learning and gives meaning to everyday life from of the provocations it causes to the teaching action and, concomitantly, to the babies' actions. It proposes a review again and with a sensitive listening, enabling the communication of what has been lived through the sharing of mini-stories that show the discoveries of the researcher teacher and the babies as protagonists and authors.

Teaching concepts of physical optics to high school students, especially those related to the behavior of light, is not a simple task. The approach to these topics is scarce, and short class time during the week are the challenges encountered. The use of experiments in the classroom is a good tool to be used to approach these subjects, mainly in the 3rd year of high school, where the subjects of modern physics are also little explored. With the use of experiments, we have the students' motivation and engagement as an additional stimulus in the presentation of the studied subjects. The purpose of this work was to develop a didactic sequence for the study of the behavior of light with experiments, the contents covered involve concepts of optics and modern physics. Our goal is to offer high school teachers alternatives to stimulate their students through practical activities appropriate to each reality. Our methodology was guided by David Ausubel's theory of Significant Learning, in the sense that the student is stimulated with a potentially significant product. The product was applied to a 3rd year high school class at a state school in the interior of the state of São Paulo. The product was developed in stages: survey of previous knowledge about the behavior of light, conducting experiments on this theme and a final questionnaire on understanding the theme. The experiments involved topics such as refraction, diffraction, interference and the photoelectric effect, all of which allowed students to discuss the concepts of the wave and corpuscular behavior of light and build their knowledge about the contents covered, in the student's notebook of modern optics and physics. From the final questionnaire and the interaction in practical experimental activities during the sequence, it was possible to verify the students' motivation and interest in the subjects covered in each experiment. The product allowed the emergence of questions, raising hypotheses and debates about the observed phenomena associated with the behavior of light.

Simulation is a widely used technique for validation and testing of routing protocols in vehicular networks (VANETs). These simulations are based on mobility models that must follow the real movement patterns of vehicles to produce realistic and accurate assessments of protocols and other vehicular network solutions. Mobility models and simulations can be based and adjusted using real vehicular mobility traces. These traces are records of vehicles positioning over a period of time, and they incorporate the behavior and dynamics that occur in the day-to-day of a city (traffic jams, the way drivers drive, routines of population or types of vehicles). Understanding the mobility characteristics of these traces helps in feasibility study of vehicular networks, understanding of factors that affect traffic conditions, configuring and conducting realistic simulations so that the design of routing protocols reacts to real vehicle movement behaviors. Therefore, a tool to produce more accurate and realistic results in these simulations is the characterization of vehicle mobility datasets. There are works that already makes this type of characterization, but few of them explore data from large cities like São Paulo. This work characterizes a dataset of real mobility traces of buses in São Paulo, extracting and demonstrating mobility and connectivity metrics found in the literature. Prior to characterization, the dataset was pre-processed using common treatments for this type of data. The metrics extraction and pre-processing were done using the Python language and the big data tool Apache Spark. The objective of this work is to demonstrate the behavior of a large urban centers, and to provide a dataset for the validation, adjustment and conduction of simulations of vehicular networks. The extracted characteristics indicate behavior patterns in the movement of buses that are repeated according to the days of the week (weekdays, Saturdays, and Sundays), period of the day, and regions of the city.

The goal of this thesis is to understand how the field of support services for ex-offenders from the penitentiary is organized in São Paulo, focusing on (re)integration of these individuals in the formal job market. The starting point of this analysis is the performance of two non-profit organizations, targeting their methodology, driven by participant observation, and focusing on the comprehension of subjective aspects through the perspective of ex-offenders that have attended those programs. The initial intention to observe the levels of employment showed to be more complex, reaching a symbolic dimension guided by ideologies connected to the neoliberal thinking. The introjection of myths encompasses ideas of entrepreneurship, self accountability and motivacional thinking, acting in a dimension that modifies the perception that the ex-offenders has of itself. However, this symbolic transformation does not necessarily bring material change. The passage rituals promoted by these NGOs produce multiple identity triggers ranging from criminal to worker, showing the permeability between identities considered opposite. The perception of the ex-offenders about the NGOs is that, although they don´t get a formal job, there is a meaningful change in the image they have about themselves, which can lead to a switch in their behavior. Furthermore, the field of actors that integrate the big network of support services for ex-prisoners from the penitentiary in the city of São Paulo has been presented to be diverse and full of relationships between government and non-government entities. This research sought to analyze the performance of government entities, NGOs, private companies and investors, adding to a total of 12 actors who find themselves in a scenario with an abundance of neoliberal ideas and practices.

Cloud Network Slicing (CNS), emerging alongside the 5G mobile network, comprises a paradigm shift in the way networks are provisioned, managed, and operated. Fundamentally, CNS fosters the deployment of a multitude of modern applications, e.g., virtual and augmented reality, 4K video streaming, and autonomous vehicles, which require ultra-low latency, high bandwidth consumption, or both. Slicing promotes the realization of such services through the allocation of computing and network resource bundles, which, as CNS mandates, are isolated from the rest of the network. Typically, such resources are arranged into wide geographical areas (e.g., into multiple countries or even continents), which implies that it is possible to pertain to distinct infrastructure providers. This exacerbates the already challenging problem of maximizing resource allocation efficiency, a feature commonly addressed by CNS architectures. In this respect, we study the optimal assignment of slices to multiple domains. Therefore, we account for slices as a collection of computing and network parts. Given specific resource requirements from slice tenants, and potentially multiple offers per slice part, we model the problem as a Mixed Integer Linear Program (MILP). We further design two heuristic algorithms, in order to mitigate the complexity intricacies that would be perceptible in large problem instances. Our evaluation results, based on a simulation environment aligned with the NECOS architecture, indicate that the MILP approach had a better performance compared to both the heuristics in choosing the cheapest offers with a fair amount of performance parameters in an adequate execution time. Our main contribution stands on the optimization methods based on the split and combine approach inserted in the novel NECOS' CNS architecture.

In Brazil, in particular, civil construction is a traditional industry that, despite the increasingly frequent technological and managerial innovations, the vast majority of work is still carried out manually. The association of functions that require the use of intense, repetitive physical efforts, improvised postures and body movements with inadequate conditions and low qualification can be harmful and cause damage to the health of workers. That said, the main objective of this work, which consists of evaluating the ergonomic conditions associated with the execution of the screed service, was built within this context from the identification of a knowledge gap and the need to disseminate the importance and impact of carrying out ergonomic analysis that can positively reflect on the worker's life. Three ergonomics assessment tools were used to carry out the analysis and obtain a diagnosis, which pointed out the ergonomic risks that the worker responsible for carrying out the screed was exposed, identifying the most critical steps and activities of this service. Such tools were: MET (The Standard Metabolic Equivalent), in which the energy expenditure was evaluated, REBA (Rapid Entire Body Assessment), in which the postures of the whole body in the use of activities were evaluated, and EWA (Ergonomic Workplace Analysis), in which the “Lifting of Loads” (physical factor), “Accident Risk” (organizational factor) and “Communication between Workers and Personal Contacts” (cognitive factor) were evaluated. In order to obtain this diagnosis, direct observations, interviews and photographic records, including filming, of workers and workstations for data collection were carried out, which were subsequently processed based on the listed ergonomic assessment tools. Among the results obtained with the realization of the case studies, the following stand out: "Materials Supply" and "Waste Removal" tasks predominating as heavy work (MET), a higher percentage of very high risk postures in the "Screed Layer Production” task, mainly during the activities of “smooth” and “rub” (REBA), and the “Mortar Production” task and “Load Lifting” factor presenting the biggest numbers of negative classifications (EWA). It is safe to affirm that the performance of the screed service presents evident ergonomic risks, especially those related to the postures required. This research proved to be contributory for notifying such risks, proposing improvements and highlighting the ergonomics associated with civil construction.

Early childhood education in the country has been offered in a polarized way between schooling practices for part-time preschools and welfare practices for day-care centers on a full-time basis. However, since the incorporation of this last stage into the education system, there has been a transformation in the provision of care due to pressure from social movements. In addition, the very conception of a child, when changing historically, created the need to formulate educational policies that advocate the balance between caring and educating - two pillars of the triad that is completed with playing - as well as advances in studies on child development demonstrated the relevance of ensuring the quality of the experiences provided to young children in children's equipment, whether part-time or full-time. This research arises from the perception that the offer of full-time work, characterized by the child's long stay within the school space, demands the elaboration of quality educational policies so that, during the entire period spent at school, comprehensive formation is offered for this audience. As a problem, he questions whether, in extending the time spent in kindergarten, children would be guaranteed to play, educate and care, thus addressing their limits and possibilities. In this dimension, the general objective of the study is to analyze the supply and attendance of early childhood education in the school system of Rio Claro, a municipality in the interior of São Paulo; its specific objectives sought to characterize this reality in the researched education school system, as well as to examine the conceptions of children, childhood and early childhood education present in the official texts for education in the city where the research was located. As methodological designs, the research was undertaken through bibliographic research, document analysis and semi-structured interviews with the management team of the municipal education department. The results of the study showed that the main challenges and difficulties for the development of full-time educational work are related to the fragmentation between the care-to-educate functions and the persistence of care concepts still present in educational practices in early childhood education that work full time, that when they understand the role of the school as a place for childcare, they offer basic care and a hobby, thus compromising the comprehensive education necessary for childhood. Finally, the research points out that, although the legislation has advanced at the federal, state and municipal levels, there is still a need for improvement so that the integral education effectively occurs in the full-time day in Brazilian early childhood education.

Biotechnology is the central object of study, it will be classified here as an activity originated in the boundary between science (chemical and biological) and engineering, under the influence of several sets of values, with a ruling expression of capital and market values in the moment of application. Thus, it ruptures with the conception that “science is value free” and destabilizes the scientific ideals of neutrality and autonomy. The main objective of this work is to reflect how the application of biotechnology is conducted and what are the consequences of the professionals actions in terms of expression of values. The method used was the literature review. The analysis undertaken in this study made possible to note the existence of “control of nature” as a necessary condition for biotechnology, which does not imply in the direct link of biotechnologies to market values. Such an assertion will be corroborated by the application of biotechnology in projects that articulate and express values of sustainability, social justice and democratic participation. Although there is a relationship with capital and market values, it is possible to apply biotechnology oriented according to a “context-sensitive strategy”. It is hoped that this discussion will contribute to the diffusion of the postmodern critique of science within biotechnology, in order to instill the critical self-awareness in biotechnology students and professionals.

In the 1990s, camelôs1 who worked in the streets and squares of Cuiabá were relocated in a new space, still precarious and far from the city center. Over the years, this space has undergone transformations, guaranteeing a "mall" structure. Workers, formerly informal, are now registered and legalized, their activities have been reframed, with the entrepreneurial ideal, a term by which they have come to identify themselves. This research aimed to understand how this reframing took place, and to what extent the entrepreneurship idea was incorporated by workers, as well, as their perceptions about the galerização2 policies implemented by the government, which were questioned by them for a long time. The analytical framework sought to recover the debate on informality and its transformations in recent decades, in a context of more flexible work relations and neoliberal polices. And also, the importance of social networks to understand the strategies used by workers to stay in the activity. The workers, now small entrepreneurs, of Shopping Popular de Cuiabá (MT) were empirical. The research consisted of observation of the work, application of questionnaires to build a profile of these workersentrepreneurs and in-depth interviews. We note the internalization of the entrepreneurial ideals and the erasure of the previous history as camelôs, which is reflected, among other things, as they reinterpret the public policies of business activity.

The research is based on the assumption that information and communication technology (ICT) provided a relational network of unity among women travelers, inspiring and motivating them to move. Therefore, the objective of this research will be to investigate before the ICT platforms the effects provided by traveling users, mainly related to the motivation that lead them to travel, their experiences resulting from travel, as well as their sharing via digital network media. As specific objectives we seek to a) Interview women travelers to understand what effects these shared experiences provide on digital media platforms; b) Describe and list the contents found; c) Identify the profile of women, as well as their main motivations for travel. The procedures resulting from the execution took place through qualitative and quantitative research using virtual ethnography. The researched sample was composed of sixty-six users with a traveling profile, three of them with semistructured interviews conducted virtually, and also, analysis of four groups of sociability in digital networks. In this study, the absence of platforms or official information produced by the Ministry of Tourism was identified. There is a lack of appropriations by public bodies, in general, to articulate better information on the topic. When verifying the answers and the semi-structured interviews, it was analyzed how much greater the complexity of each personal experience because it managed to show a small part of the situation experienced by each one of them.

The teacher education of Brazilian researchers abroad favors their insertion in international collaboration networks, through international scientific exchanges and partnerships, contributes to the success and quality of the performance of the Graduate Programs, generating results that benefit society. Several bibliometric indicators have been used in the performance evaluation of researchers, universities and countries, at national and international levels, such as impact and internationalization indicators, calculated from the citations received by the articles. The objective of the research was to investigate the relationship between the teaching abroad, represented by the completion of a doctoral course and / or postdoctoral internship abroad and the international collaboration, represented by the international co-authorships present in the institutional scientific output indexed in the database Web of Science (WoS). The research method used was the exploratory case study, and the case-unit, the Federal University of São Carlos (UFSCar). A bibliometric study was performed using the Lattes Platform and WoS as sources of information, and the sample analyzed comprised 12,787 bibliographic records and 1,915 Lattes Curricula of active teachers. As a result, a set of indicators was elaborated on the scientific output of teachers with and without training abroad and their impact on international scientific collaboration, through analysis of co-authorships. From the results obtained, through data enrichment, it was possible to ascertain the positive relationship between the training of doctoral or postdoctoral professors abroad with the formation of international networks and co-authorships, contributing to the impact of institutional scientific output. Initial considerations indicate that the results and discussion of this research can contribute to the improvement of initiatives including the development of indicators of scientific and technological production in Brazil, involving internationalization and, consequently, for the improvement of the National Graduate System, by providing a better understanding of international scientific collaboration, based on investigating the training and performance of Brazilian researchers.

Context: Software testing plays an important role in quality assurance. Testing techniques and criteria help the tester to develop and assess test suites. Mutation testing is a fault-based testing criterion commonly used to evaluate the quality of test suites. However, a high computational cost to generate and execute the mutants and the existence of equivalent prevent mutation testing to be widely applied in practical situations. In this sense, it is important to propose studies to overcome such problems. Objective: This work presents an approach that combined mutation testing and the concept of primitive arcs, used in the context of control-flow testing criteria, to reduce the cost of mutation testing. Overall, the goal was to verify if the execution of a subset of mutants located on the primitive arcs of a program under testing reduces the number of mutants and maintains a high mutation score. Next, this work evaluated the relationship between minimal mutants and primitive arcs. If both hypotheses confirm, it is possible to design new testing criteria based on the results obtained. Method: This work presented an experimental study to evaluate the proposed approach. To carry out the experiment, this work considered a set of 29 programs in C already used in other studies involving mutation testing. Results: The results showed that the approach reduced the number of mutants and achieved a high mutation score. Besides, the results showed that the primitive arcs concentrated a high percentage of minimal mutants. Then, the approach was compared to random mutation. The results showed that mutation on primitive arcs was slightly better than random mutation. Finally, this work presents a set of testing criteria based on the results obtained. Conclusion: Although powerful to detect faults, mutation testing still requires some improvements to large use in industry. The proposed approach may guide further works once the results obtained showed that the combination of mutation testing and primitive arcs might be a promising alternative. Thus, a broad experimental study using industry level programs and different test suites, may bring different results and hence, bring some contribution to the community.

The present research aimed to investigate how the Municipal Education System of Bauru has interpreted and translated national public policies for IE, and how these influenced the conceptions and directions assumed for playing expressed in its municipal document. Through documentary analysis of the notebooks produced by the Coordination of Early Childhood Education - COEDI and by the Secretariat of Fundamental Education - SEF (BRASIL, 1994-1998), the National Curriculum Reference for Early Childhood Education - RCNEI (BRASIL, 1998) and the National Curriculum Guidelines for Early Childhood Education - DCNEI (BRASIL, 2009), and the Pedagogical Proposal for Early Childhood Education of the Municipal Education System of Bauru (PASQUALINI; TSUHAKO, 2016), sought to understand how the main socio-historical, political and theoretical milestones influenced public policies for Brazilian early childhood education, and the defended conceptions and guidelines for playing. The theoretical framework for studies on playing is supported by the Historical-Cultural Theory, and the methodological framework is inspired by the Policy Cycle Approach (BOWE; BALL; GOLD, 1992, 1994). The results presented from the contexts of influences, text production and context of practice point to distances and similarities between public policies for national and municipal early childhood education. This study is part of the research line “Assessment and public policies in early childhood education”, of the study group EDIPIC- Early Childhood Education and Small Childhood in Context, at Federal University of São Carlos/SP.
