The present doctoral dissertation was written in manuscript format. It consists of a summary of the dissertation in non-technical language, a theoretical essay, and three experiments. The theme addressed in this work is the effects of verbalization, from the experimenter and the individual, on the participants' food intake. The general objective was to verify if verbalizations would decrease the amount of unhealthy food eaten and if the use of an intermittent reinforcement schedule would promote the maintenance of this behavior. Three experiments were conducted, with children from 6 to 9 years old, and, in all sessions, nine pieces of healthy food (fruits and nuts) and nine pieces of unhealthy food (e.g., chocolate, cookies, packet snacks) were presented to them. In Experiment 1 it was examined the effect of a rule provided by the experimenter on the amount of the child's food intake. The rule signaled to child that they could eat only one piece of unhealthy food and as many as they wanted from healthy ones. There were no programmed consequences for following or not following the rule. Also, it was verified whether the rule presented by itself or accompanied by information of health and nutrition would have any effect on the responses. The results indicated that six out of the ten children decreased the amount of unhealthy food eaten during the rule presentation throughout the procedure, two children only decreased it at the beginning of the procedure, and two others did not change their behavior compared to the baseline. Furthermore, the presentation of the information did not change the responses, and all children increased unhealthy food intake when the rule was withdrawn. Experiment 2 aimed to verify whether the presentation of differential consequences for rule-following and, subsequently, its gradual withdrawal and its total suspension, would promote the maintenance of the behavior of eating less unhealthy food after removing the rule. For this, the children were told that they would earn one stamp, which could be exchanged for a prize, if they followed the rule. Otherwise, they would not earn the stamp. The consequences were provided in a continuous reinforcement schedule, then in intermittent reinforcement schedule, and, finally, they were no longer presented. The results showed that all children decreased the amount of unhealthy food intake when the rule was presented accompanied by the stamp, and five out of the seven children maintained their behavior after withdrawal the consequences. Finally, Experiment 3 examined the effect of a promise on unhealthy food intake. The child promised to eat no more than one piece of unhealthy food and as many as they wanted from healthy ones. The consequences were provided contingent only to the promise, and, as in the previous experiment, they were also withdrawn gradually, until their total suspension. The results indicated that the promise decreased the amount of unhealthy food eaten for five out of the six children. Two out of the six children were exposed to the correspondence training because they did not present correspondence between promise and eating. For them, the training was effective to promote correspondence and, consequently, reduced the amount of unhealthy food eaten. Five out of the six children maintained their behavior after removal of the consequences. Another interesting result was that there were children who increased the amount of healthy food eaten: two in experiments 1 and 2, and three in Experiment 3. The analyzes indicate that the rule changed the behavior, however, for higher effect and maintenance, the rule must be presented with differential consequences. Besides, the promise and correspondence training also increased the frequency of target behavior. Establishing operation is discussed as a variable that possibly influenced the responses.

Wastewater treatment represents an important stage of basic sanitation and the conditioning of the generated sludge is a major challenge, due to high operating costs. In this sense, the use of natural conditioners from agro-industrial residues that assist this process becomes a promising alternative. The goal of this work was to evaluate the application of corn straw lignin as a conditioning polymer in the dewatering of sludge from a Wastewater Treatment Plant. The lignin samples were extracted by soda pulping, with NaOH, and the Klason method, and later characterized using the Fourier Transform Infrared (FTIR), 1H Nuclear Magnetic Resonance (1H NMR), Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), UV-Visible Spectroscopy and Thermogravimetric Analysis (TGA). The lignin samples obtained by the Klason method were applied to the sludge to evaluate its dewatering. The highest yield of lignin obtained was 2.22% for the soda pulping and 24.6% for the Klason method. From the characterization, a typical chemical composition of lignins was observed, with the presence of hydroxyl, aromatic, methoxy and aliphatic groups. Its morphology was predominantly straight and amorphous. In its elemental composition, in addition to carbon and oxygen, the elements sodium and chlorine were identified as residues of the extractive process. The thermal stability of the sample was also observed even at high temperatures. After sludge conditioning, lignin had no influence on sludge dewatering, due to the insolubility in water and the low density of loads, which indicates the need for chemical modification of the lignin to act as a sludge conditioning agent.

I am going to start this narrative with the question I have heard for many years and sometimes I am still listening: Have you always wanted to do medicine? Well, I do not remember the exact day when I decided to do medicine, I have no medical relatives and as a child I did not have any important reference in the area, but I have old memories of having this certainty within me. Before that, I came to imagine myself as a biologist and working on beaches with protection for turtles, but over time I became disconnected from this idea and became more certain about Medicine. The process of passing the entrance exam was not the easiest. Since the beginning of high school I dedicated myself to this goal and suffered a lot each year of entrance exam, I considered myself a failure because I was in that situation. I thought several times that medicine was not for me. After 3 years of studying with lots of tears and certainly a lot of maturing, I went to UFSCar. Why UFSCar? I don't even know. In the last 3 minutes of choosing ENEM faculty I decided to put here, without knowing anyone, the method or the city. The next day, I received approval.

This thesis aimed to investigate the historical period between the years 1931 and 1942 of the current Parque Estadual da Ilha Anchieta (PEIA), when was in place the Presídio Político da Ilha dos Porcos (1931-1934), the Colônia Correcional da Ilha Anchieta (1934-1939) and the Presídio Político da Ilha Anchieta (1939-1942). As this is the first academic research about the above mentioned period, the primary purpose was to describe, in a detailed and critical manner, the pieces of information identified by the documents, within the material possibilities of the multiple sources consulted. The secondary purpose was to investigate the profile of the individuals transferred to these incarceration institution to comprehend the role of the same institution at the multiple social and political context of São Paulo state during the historical period and the daily events that involved that entire population: detainees, civil servents, militaries from Força Pública and their respective relatives. After the investigation, it was possible to determine that the Presidio Político da Ilha dos Porcos (1931-1934) received at least twenty-five (25) national and foreign detainees for political activities and among them are important members of the Partido Communista do Brazil (PCB), as well as the secretary of the União dos Operários em Fábricas de Tecidos (UOFT), the largest union in the state at that time. It was also possible to identify cases of Brazilians detained in Ilha dos Porcos who, shortly afterward, were deported outside national borders, from the states of Matto Grosso and Rio Grande do Sul. It was also revealed that, at least between September 1934 and January 1936, the Colony was illegally reactivated: without regulation and an ordinance from the government, it worked under “secrecy” in portion of the civilians detained there before the Judiciary, the Executive and even part of the São Paulo police itself at a time when Brazil was already under the democratic regimen of the 1934 Constitution. For the third period, from 1939-1942, the moment of the political prison, it was possible to identify detainees that were arrested under the justification of “estado de emergência” [state of emergency] and “manutenção da ordem pública” [Maintenance of public order], reports of forced labor, the presence of military personnel affiliated to Ação Integralista Brasileira (AIB) serving in the deployment of Força Publica and the increase in the number of deaths in the early 1940s, which may have accelerated the process of transforming that space into the Instituto Correcional da Ilha Anchieta (ICIA). During this period the island not only received communists, integralists and all categories of detainees but also “dementes” [person with dementia] and “mendigos” [beggar]. Thus, I argue that Ilha Anchieta was the institution of maximum confinement in the state of São Paulo, playing the role of “válvula de escapamento para casos insolúveis” [exhaust valve for insoluble cases] based on police actions that practiced a “serviço de saneamento” [sanitation service] and “profilaxia social” [social prophylaxis] in the urban environment of São Paulo and Santos. To this end, this research explores, in a pioneering way, the archive of the Parque Estadual da Ilha Anchieta (PEIA) and different collections already known from the Arquivo Público do Estado de São Paulo (APESP), mainly that of the Departamento Estadual de Ordem Política e Social (DEOPS) and of the Academia de Polícia Civil (Acadepol). In addition, the research for newspapers of the time from the Hemeroteca da Biblioteca Nacional Digital (BNDigital) from Fundação Biblioteca Nacional (FBN), in addition to the research on state legislation in the historical collection of the Assembleia Legislativa do Estato de São Paulo (ALESP) and research in the Diário Oficial do Estado de São Paulo (DOSP), based on the archives from Imprensa Oficial.

This dissertation aims to evaluate the capacity of fiscal policy to smooth the cyclical fluctuations of the Brazilian economy. A theoretical discussion is held regarding the possibility of stabilizing the level of activity through public spending and / or through changes in taxation, highlighting the differences between the conventional and the Keynesian view. Subsequently, an assessment of the fiscal policy guidelines in Brazil between 1995 and 2018 is made in order to provide historical and institutional elements for empirical analysis. From the calculation of fiscal multipliers for various components of primary expenditure and for net primary revenue, the empirical investigation admits as general hypothesis that the responses of the aggregate product to the shocks in the various fiscal variables differ between the recessive and expansive phases of the Brazilian economic cycle during the period 1997-2018. Two models are estimated: a structural VAR of the linear type and a non-linear VAR with regime change from the Markov-Switching process. In a second step, Public Sector Net Debt is included in both models to verify whether public debt overestimates fiscal multipliers. Public debt is not a predominant variable for the magnitude of the fiscal multiplier, as part of the literature suggests, as the economic cycle prevails over the size of the fiscal shock. In general, there are two contributions to the debate and to empirical research. The first is the estimation of fiscal multipliers for the Brazilian economy in a non-linear model with public debt. The second is the discussion of the results in the light of the economic policy actions of all governments in the period studied, relating them to the historical evolution of macroeconomic thinking on fiscal policy.

Mangroves are extremely important ecosystems, both for nature cycles and for humans. They provide a series of benefits, such as maintenance of fishing resources, control of hydrological cycles, maintenance of water quality, stabilization of the coastline, sediment retention, scenic beauty, among others. They are situated by definition between terrestrial and marine environments, being covered and uncovered permanently by the tides, and may suffer impacts from both sides, such as through the sanitary sewage of upstream urban areas, or in oil spill by vessels at sea. This location, as privileged as it is fragile, can make it a symbol of the Coastal Zone, which in Brazil is considered by the Federal Constitution a national heritage. In this country, the National Coastal Management Plan aims to organize this part of the territory, involving both land and ocean and the transition ecosystems between them, seeking economic and social development linked to environmental conservation that guarantees human activities as their own and life quality of the population. These objectives can be achieved with the Coastal Ecological-Economic Zoning, instrument incorporated in the legislation to order the territory, directing how and where different human activities can be developed, as well as determining forms of environmental conservation. Its formatting is so relevant that the knowledge of which areas are subject to urbanization, and which degraded areas need to be reforested, or also which places allow fishing or installation of port structures. Thus, this public policy has a fundamental role in the conservation of mangroves. This research aims to verify whether the review process of the Coastal Ecological-Economic Zoning of the North Coast of São Paulo, completed in 2017, increased or decreased in relation to the previous version of 2004 the protection of the mangroves in the region. For that, the two versions were compared considering both their texts and maps, as they are inseparable elements, as well as correlating with the use of the environments in 2016, and also with the future expectation of using the environments in both versions. The results show that the urban area tends to more than double, increasing the impacts that already exist in the mangroves due to the low coverage of public services infrastructure. Urban expansion is strongly directed towards extensive areas of native vegetation, which are expected to weaken the sensitive hydrological dynamics of mangroves, and the marine environment now has more permissible uses that can impact mangroves. The legislation that should be used in line with the Coastal Ecological- Economic Zoning to maintain the region's environmental quality has not been sufficiently observed, causing environmental degradation and the life quality of the population.

Government procurement moves an important part of the budgets of the federal entities, therefore, the good management of the bidding procedures is essential to avoid the misuse of public resources, requiring from public managers the capacity to instruct the processes and speed up their conduct. The Auction, a bidding modality regulated by Federal Law No. 10,520 / 2002, intended exclusively for the acquisition of goods and the contracting of common services,with performance and quality standards, objectively defined in the Notice, by means of usual specifications in the market, it is used with great frequency by Organs public agencies, for conferring to the competitions, greater speed, economy, competitiveness and advantage in the proposals. Considering thatthe Municipality of Itapeva, carried out in the period from 2011 to 2018, approximately 64% of its purchases through the use of Presentials, this work has as object this type of processes, since it is on these that the highest charges fall for results andspeed in processing. In this way, this research has as its general objective -to identify opportunities for improvements to remedy / correct the critical factors in the bottleneck units, which compromisethe speed and quality of the instruction of the bidding processes of the On-Site Auction, triggered for the acquisition of common goods and services in the municipality of Itapeva / SP. The research classified as applied, descriptive and qualitative, was outlined as a single Case Study, having as its locus of research the Municipality of Itapeva / SP and the activities developed by the Department of Materials and Supplies and other public departments responsible for processing the bidding processes, thus, it proposes the combined application of the ProcessManagement Methodology or Business Process Management -BPM approach and the Theory of Constraints, as tools for continuous improvement. Based on the application of the tools, the current situation was mapped -“As is” mapping of the processes and the verification of the execution times of the activities that make up the procedure and the format of the procedural instruction, through the collection of documentary data and semi-structured interviews. As a result of the research, 11 (eleven) improvement proposals were elaborated, to be applied in the bottleneck environment, the Department of Materials and Supplies, in order to facilitate the progress of the works performed by the sector, giving greater speed and quality to the bidding procedures. With the realization of the research it was possible to verify the contributions of the application of the approaches to the bidding processes, which may be implemented by the Municipality of Itapeva, as well as by other federal entities, in the investigated bidding modality, as well as in the other bidding modalities defined in the federal legislation, including, in other types of administrative processes, making public actions more transparent, establishing flows andstandardizing procedures.

This research aims to characterize the processes of reading and interpreting the work Auto da Barca do Inferno, by Gil Vicente for the 1st grade of the Chemistry Technician Integrated into High School of a State Technical School in the countryside of São Paulo and to problematize the didactic potentialities of audiovisual production for the development of critical reading. Our theoretical foundation is based on authors who discuss active methodologies (MORAN, 1995, 2007, 2015, 2018; VALENTE, 2018), critical reading (FREIRE, 1983, 1989, 1996) and literacy (SOARES, 1988, 2003, 2004, 2017; COSCARELLI, 2017). We proceeded to the analysis of the production process of audiovisual texts by students, elaborated during the classes of Portuguese Language and Literature in 2019 through a case study. The analysis criteria were: the description of the students (costume, makeup, satisfaction); reconstruction of dialogues (language used, quotations and intertextuality); description of the environment (location used for rehearsals, filming and scenarios); description of special situations: autonomy, interaction between teams, innovation, creativity and use of sound effects). The results of our analyzes show didactic potentialities in the production of videos for the development of critical reading in Portuguese language classes such as better understanding of the work read, vocabulary learning, as well as the ability to reflect and communicate, autonomy, resilience, critical thinking and aptitude to solve problems.

Demand for new implants with improved bioactivity, corrosion resistance, and optimal mechanical properties has been increasing considerably. In this sense, different surface treatments are applied in titanium alloys to improve their osteointegration process. Nevertheless, the developments of new bioactive surfaces could cause a considerable reduction in fatigue and corrosion strength leading to catastrophic failures in clinical use. For these reasons, this work studied the biocompatibility, corrosion and fatigue performance of Ti-12Mo-6Zr-2Fe alloy treated with three different surface modifications, namely, chemical surface treatment (CST), nanotubes (Nt) and nanopores (NP). Samples were immersed in simulated body fluid (SBF) solution during different periods, 0, 1, 7, and 14 days. After 14 days immersed in SBF, samples with CST showed high hydroxyapatite (HAp) formation; Likewise, samples with Nt and NP exhibited lower and moderated HAP formation, respectively. In samples without surface treatment was not observed HAp formation. The electrochemical behavior was studied through polarization curves and electrochemical impedance spectroscopy (EIS). Samples with Nt and NP displayed higher corrosion resistance and lower passivation current (Ipass) compared with untreated samples, after 14 days of immersion in SBF; samples with CST showed the worst corrosion performance for all the surface conditions studied. Furthermore, within the framework of electrochemical investigations, EIS results of Nt and NP samples showed a characteristic behavior that could not be modeled by traditional equivalent circuits. Thus, it was proposed a two-channel transmission line model for analyzing this impedance results, leading to a successful fitting of the EIS data. Finally, was observed a reduction of the fatigue resistance in the samples treated with NP and CST, associated with hydrogen embrittlement processes, due to the pick-up of hydrogen during the respective surface treatments.

This ethnography aims to reflect on the school reinsertion of young people in compliance with socio-educational measures in an open environment (MSE-MA), in response to the demands of re-socialization present in ECA and SINASE and required by the Judiciary. The effort is to understand the ways in which young people experience the practice of compulsory school reinsertion taking into account the different trajectories and relationships woven and legitimized in the tangle of institutions present in this plot. In addition, I propose to problematizing the notion of socio-education as a punitive method for a possible re-socialization and how these terms are placed in the context of this dissertation where school reintegration plays a fundamental role. The research was carried out in three stages and in MSE-MA services located in three peripheral regions of the city of São Paulo, with three different modes of insertion in the field. The insertions and the actions in each three of the research stages, first as a technique in the implementation of the MSE-MA, later as an educator and later as a researcher, are problematized and deepened as ethnographic experiences. For this reason, I designated my ethnographic production in three times: three different perspectives in different chronological and spatial times.

Thermal acclimation is suggested to provide a reversible physiological adjustment in response to environmental changes, conferring resilience in a climate change scenario. Since amphibians may be more vulnerable to habitat modification because of their life cycle dependence on both land and water, it is critical to identify species’ ability to acclimate in warming climates. Here, we investigate the effects of temperature acclimation on tadpoles of a stream-breeding savanna tree frog (Bokermannohyla ibitiguara) and the relationship between the thermal conditions experienced in their microhabitat. We quantified variation in thermal physiology by measuring routine and maximum metabolic rate (RMR and MMR, respectively) at different test (15, 20, 25, 30 e 34°C) and acclimation temperatures (18 and 25°C). In addition, we measured body characteristics of the two groups and the heart rate (fH) before and after autonomic blockade with atropine and sotalol. Further, we determined the critical thermal maximum (CTmax) and warming tolerance (WT=CTmax-Tmax), which were not affected by acclimation. The routine and maximum metabolic rate and fH increased with acute exposure to high test temperatures, although the acclimation did not affect significantly the maximum metabolic rate, fH or the autonomic tones. In addition to this absence of physiological compensation, we observed a decrease in aerobic scope in the group acclimated to 25 °C, followed by a 53.8% reduction in body mass in the tadpoles of this group. In conclusion, the tadpoles of B. ibitiguara inhabit in a thermally stable environment and are not able to thermally acclimate to high temperatures like 5°C above those found in their micro-habitat, making the species more vulnerable to climate changes or/and with degradation of their habitat.

In this work, a study was carried out on the main types of process control logic, making comparisons and simulations focusing on temperature control of an alcoholic fermentation process in a bioreactor with a thermal jacket. Before proceeding to the mathematical modeling of the proposed system, a bibliographic review was made studing the motivation for using temperature control in fermentative processes, the theory of process and process control and finally the concept of three important control logics, onoff, PID and Fuzzy. To present the structure of a Fuzzy control, an introductory study was made on Fuzzy logic itself and how it can be used in process controls. The free software Scilab was used to simulate the compared logics. The results of the simulations made for the process in question indicated that the biochemical system behaved as expected, resulting in cell growth and ethanol production while the substrate is fed and then consumed. The results obtained also indicated that for conventional controller bioprocesses, which are dynamic systems, conventional controllers such as on-off and PID have some stability restrictions. On the other side, the results show that the Fuzzy logic can be adapted with good stability, although requiring a fine tuning by a specialist. Finally, it was possible to see in the result of each simulation that the system behaves within the predicted theory and thus make the relevant comparisons and conclusions.

The general objective is to analyze which manifestations or perceptions predominate when the didactics of historical-critical pedagogy are used in the teaching and learning process in high school students. For this purpose, this didactic was used during philosophy classes in a high school classroom at a public school in the city of Sorocaba and its results were compared to those obtained with another class in which the didactics / class structure were applied. in the “student notebook” of the State Education Network of São Paulo, based on reflections from the analysis of historical-critical pedagogy and the experiences of implementing this theory in the State of Paraná, especially in the city of Francisco Beltrão, and in criticism of technical-reproductive model of the State of São Paulo and the implementation of historical-critical pedagogy in the municipality of Limeira-SP, the research found elements to structure a proposal for the application of the historical-critical didactics presented here. After a study and analysis of the theory, some experiences of implementing historical-critical pedagogy and its didactics were analyzed, first in the State of Paraná and later in Limeira-SP. Still in the practical analysis of historical-critical didactics, the teacher-researcher presented an action research that he developed with his high school students to observe how historical-critical didactics happen in school daily life in comparison with the use of the “student notebook” used by the State Education Network of São Paulo. In view of the theoretical framework of historical-critical didactics, the experiences studied and the practice developed in action research, it was thus possible to discuss the proximity, distances and challenges of implementing historical-critical didactics. What is observed is that it is more distant from its implementation in Teaching Networks and closer to its implementation in classrooms across the country. For this to accelerate in this political, economic and social moment that Brazil is going through, it is necessary to invest in continuing education and invest in the autonomy of the teacher and in his relationship with other educators and with the students so that new experiences emerge in the daily life of the classroom. class with historical-critical didactics, making education a space that contributes to social transformation, built through basic work.

When compared to solid reinforced concrete slabs, the ribbed slabs are designed in order to make the most efficient use of the qualities existing in the materials that constitute them, through the cover and ribs set, the use of concrete is optimized for compression and the use of steel to withstand the tensile stresses existing in the slabs. Due to this better use of the materials used in the construction of the ribbed slabs, these slabs are considered more economical than the solid ones, this for larger spans (from 6 or 7 meters). However, the mandatory verification of reinforced concrete structures for the fire situation tends to diminish this economic advantage possessed by the ribbed slabs, because when checking a slab to the fire situation, the thermal insulation capacity of this element is also verified. so that minimum thicknesses of concrete slabs are required. Thus, in this work we studied the design of solid and ribbed slabs in reinforced concrete in the fire situation using mostly two standards of the Brazilian Association of Technical Standards (ABNT), ABNT NBR 6118: 2014 - Design of reinforced concrete structures and ABNT NBR 15200: 2012 - Design of reinforced concrete structures in a fire situation with the tabular method. The dimensioning of the structures for different design impositions was carried out with the aid of the CAD / TQS software, and through the iterative process, the dimensions of the slabs were obtained so that the arrows obtained were as close as possible to the maximum arrows of each span. When the slabs were dimensioned and detailed, the quantities of steel and concrete used in the design of each slab were obtained. Thus, through the tables and graphs generated in the Excel software, a comparative study was carried out between the solid and ribbed slabs for different contour situations. (spans, classes of environmental aggressiveness and height of the building). A comparative study between the different construction methods was carried out, the use of solid and ribbed slabs in the structural design was discussed.

In several regions of the world, collective agroindustrial projects are important initiatives for the reduction of poverty and hunger. However, they are exposed to a set of particularities that make it difficult and set challenges to success in their implementation. These characteristics require the use of feasibility analysis tools that can incorporate such particularities. Aiming to contribute to the resolution of this problem, this research has as main objective the construction of a model to support decision making, which incorporates the conditions and determinants that affect the performance and viability of the collective agroindustrial projects of industrialization and commercialization in Brazil. A systematic literature review was carried out to identify the performance constraints of collective agroindustrial projects. The proposed model was structured via Simple Multi-Attribute Rating Technique (SMART) modeling, aiming at weighting weights for the factors and determinants from a panel with twenty interviews with experts. The developed model was applied to a portfolio with six collective agroindustrial projects. This application aimed to measure the impact of each determinant in the evaluation of the projects, build the proposed index in real situations and evaluate the results of the implementation of the projects using the proposed analytical tool. The results achieved include the development, proposal and testing of a Project Success Probability Index - IPSP for the analyzed initiatives. The proposed analytical method, with emphasis on the IPSP, proved to be efficient in identifying the most important factors for the success of collective agroindustrial projects.

This study assumes that the teaching professional identity is constituted as an interaction between the individual and his subjective experiences, both at the individual and professional levels. The objective was to investigate how the process of constituting the professional identity profile of teachers who work in early childhood education (with children aged 3 to 5 years). We considered their life stories, training processes and professional performance. Theoretical contributions to the analysis of the investigation was based on the contributions of Tardif (2002, 2013), Pimenta (1999), Nóvoa (1992, 1997, 2019), Dubar (2005)) - in the field of the theme on identity and professional knowledge - and in Assis (2007), Kishimoto (1999, 2005) and Rosemberg (2012), on the understanding of professionals in early childhood education. The research had been based on a qualitative methodology through an exploratory-descriptive study, carried out through questionnaires with open and closed questions, with 14 teachers of early childhood education. The data were organized into 05 axes of analysis (Identity and singularity; Initial and continuing education; Teaching professionalism; Teaching knowledge; Professional practice). The results shows the importance of this type of investigation, allowing us to have a more accurate look at how the teachers of young children act and face the problems of their realities, which leads us to a more in-depth dialogue and an analysis in a more critical and aware of issues related to real situations that arise in the context of early childhood education that enable a constant reflection of practice and, consequently, of the constitution of identities.
