The work proposes to understand how the Career Plan for the Public Magisterium in the Municipality of Piracicaba is being established. This is an instrument of the Human Resources Administration, foreseen by the Brazilian educational legislation for teaching categories, especially for Basic Education. The objective is to understand the specificities of the elaboration of a Career Plan for Public Teaching in the Municipality of Piracicaba, through the analysis of the compatibility of incentives for professional development, in a career, with the organizational objectives of the City Hall. The study focuses on a literature review on the topic of strategic management of people in the public sector, the study of positions and careers, and also the concept of teacher professional development. The Systematic Bibliographic Review focused on career planning in public education was used to map the field of study. As qualitative and quantitative descriptive research strategies, data triangulation is built around 1) Participant Observation, through the political-institutional context of the Municipality of Piracicaba and the Municipal Department of Education aligned with the researcher's experience as a natural member of the Network Municipal Education; 2) Documentary Analysis that breaks down Complementary Law Projects nº 11/2004 and nº 17/2017, which deal with the legislative matter object of this study, in Piracicaba, and were both rejected and archived; and 3) the application of a Survey, through a questionnaire proposed to the target audience of Piracicaban teachers, whose results show an average profile of municipal teachers. From the triangulation of data between Participant Observation, Document Analysis and Survey it led to the conclusion that the City Hall offered career plans consistent with the professional development of teachers, valuing career progression based on academic title, length of service, functional performance and continuing education courses for professional improvement and qualification. The plans, however, have yet to be approved and implemented. The City Hall's objectives, in this sense, consist of complying with current educational legislation, consolidating the structure of the Municipal Education Network and valuing teaching professionals. At the end, possibilities for future studies are proposed related to the teacher's participation in the elaboration of these plans, the legal forecast of career plans for other servants of Basic Education, and the possibilities of access to school management positions.

About 4% of the GDP of industrialized countries is destined to the maintenance of materials deteriorated by corrosion and the corrosion of reinforcements contributes to a significant portion of this percentage. Another problem in civil construction is the exacerbated use of natural resources, such as sand and gravel, used as aggregates for the production of concrete. Over time, these resources became scarce and the use of recycled aggregates became necessary. The author's research group has been working with eco-efficient waste for two decades, and this knowledge was combined with the general objective of this work, which was to evaluate the corrosion of reinforcement in cementitious composites with the incorporation of two residues separately: sugarcane bagasse ash sand (SBAS) and water treatment sludge (WTS), both used as fine aggregate in concrete pore solutions (CPS) and in cement composite samples. The innovation of this work lies in the use of the corrosion assessment technique in CPS for concrete with residues. For this, carbon steel samples were immersed in pore solutions of cementitious composites with SBAS and WTS in pure solutions and solutions contaminated with aggressive agents to the reinforcement (chlorides and carbonates). In an electrochemical cell, the monitoring of the open circuit potential, the electrochemical impedance spectroscopy and the linear scanning polarization were carried out to verify the corrosion of the steel in the different solutions studied. In addition, the results obtained were compared to the results of similar evaluation on cementitious composites of the same traces of WTS and SBAS. Based on the analyzes carried out, it was possible to conclude that the incorporation of SBAS is beneficial in terms of corrosion resistance of reinforcements, and can be used as a fine aggregate to replace 30% by mass with natural sand in concrete for structural purposes in marine environments. However, 3% of LETA replacing natural sand in concrete caused the passivation film not to form properly on the reinforcement. Therefore, in this case, concrete with this WTS percentage cannot be recommended for structural purposes in a marine environment.

Lignocellulosic biomass is one of the renewable energies indicated in the replacement of fossil fuels for the production of bioenergy and mitigation of climate change, given its wide distribution and quantity, considering the different types of biomass and its residues. However, it is necessary to study the thermal behavior of biomass in order to achieve greater energy efficiency. A usual methodology to understand the thermal behavior of biomass is thermogravimetric analysis (TGA). As lignocellulosic biomass has a complex and heterogeneous composition, in TGA the decomposition ranges of its compounds overlap at some points. Thus, thermogravimetric analysis of biomass-cellulose, hemicellulose and lignin compounds has been used; in order to elucidate the degradation ranges and parameters of each constituent separately and how they interfere in the thermal degradation of in natura biomass. The objective of this work was to thermally analyze the biomass of eucalyptus wood chips and sugarcane bagasse, as well as their compounds – cellulose, hemicellulose and lignin; in order to understand more about the combustion and pyrolysis processes of biomass. Proximate analysis and chemical analysis of the biomasses were performed to obtain the components of the biomass and analyze in thermogravimetry. The materials analyzed were: microcrystalline cellulose, cotton, xylose, kraft and organosolv lignins, eucalyptus chips (in natura, without extractives, holocellulose, alphacellulose, lignin) and sugarcane bagasse (in natura, without extractives, holocellulose, alphacellulose, lignin). The xylose DTG curve showed two degradation peaks before 350 °C and stabilized the degradation near 400 °C, indicating less resistance to thermal degradation. The DTG curves for cotton, microcrystalline cellulose, alpha cellulose from eucalyptus chips and alpha cellulose from sugarcane bagasse showed a narrow degradation range and a sharp peak of maximum degradation around 300-400 °C. The DTG curves of lignins (kraft lignin, orgnosolv lignin, eucalyptus lignin and bagasse lignin) showed a less pronounced degradation, covering wide temperature ranges - between 270 and 560 °C, proving the stability and resistance of the material to thermal degradation. Sugarcane bagasse proved to be more thermally stable than eucalyptus. In general, for both eucalyptus and bagasse, the TG and DTG curves of in natura biomass, without extractives, holocellulose and alphacellulose were similar, but there was a gradual omission of the peak corresponding to the deflection temperature before the point of deflection. maximum decomposition (Tsh) and the narrowing of the base of the maximum degradation peak in the DTG curve, a behavior that is probably associated with the loss of secondary/extractive compounds and hemicellulose. To accurately plot the TG and DTG curves, as well as perform kinetic studies, it is recommended to use different heating rates.

As soon as they enter the military institutions, all individuals are obligatorily submitted to a rigorous period, called Basic Military Training (BMT). In this sense, the present study aimed to evaluate and characterize musculoskeletal injuries, training load, recovery, creatine kinase (CK) concentration and skin temperature during the BMT of the Air Force Academy (AFA). This is a longitudinal study, carried out during the AFA TBM, lasting 37 days. To verify the musculoskeletal injuries that occurred during training, a daily survey of medical and physiotherapeutic records was carried out. After the military training instructions, the participants were evaluated through the subjective perception of exertion (SPE) and once a day, always before the first activity, they were asked about the current stage of recovery using the total quality of recovery scale (TQR). From the SPE, the total weekly training load (TWTL) and the monotony index were calculated. In the pre-BMT period and at the end of each week, CK concentrations and skin temperatures were measured. A total of 103 male soldiers were evaluated. During the BMT, 121 musculoskeletal injuries were recorded, which were suffered by 64.1% (n=66) of the military. The body region with the highest frequency of injuries were the lower limbs (75.2%). Of the participants who suffered at least one musculoskeletal injury, 42.4% (n=28) were excused from activities for at least one day. The TWTL of week 2, 20010.1±4010.1 (U.A), was the lowest when compared to the others (p<0.001). The weekly averages found for monotony were higher than 2.6±0.5. For TQR, the second week was the one with the worst recovery (11.5±1.6) (p<0.001). CK increased right at the beginning of training and remained throughout the BMT with values higher than the initial assessment. Bilateral asymmetries greater than 0.5º were found in several body regions, with the knee being the most affected region. A positive correlation was found between CK and the temperature of the biceps, pectorals and knees, but only in a few weeks. The findings of the present study indicate that the TBM had a high percentage of injuries, with the lower limbs being the most affected region. The weekly training loads were high, showed no progression and had high monotony. Recovery throughout the stage was not adequate. CK increased at the beginning of the stage and remained high. Skin temperature showed asymmetries, but these did not correlate with CK concentration.

Higher Education Institutions (HEIs) have occupied a distinctive role in society: they are predisposed to be at the forefront of social change and to deal with problems. In this context, the aim of this work was to investigate how the theme of sustainability is dealt with and the application of in HEIs. To achieve this objective, the work proposed to explore how sustainability in HEIs was addressed in the literature, to evaluate the selected publications, to integrate the dimensions of sustainability to the purpose activity of HEIs and how sustainability is operationalized in Brazilian HEIs. As results and discussion, the published articles were identified, with relevance and comprehensiveness and the main types, methodologies, scales, dimensions and approaches were analyzed. In addition to proposing the integration of the dimensions of sustainability with the end-activity of Brazilian HEIs, by means of structural equation modeling. Finally, the evaluation of the application of sustainability demonstrated that although there are constant efforts by both public and private HEIs, sustainability still reaches low levels of application in most of them. Future work needs to conduct the assessment in a multinational context and better investigate the interaction between sustainability in public and private HEIs.

Self-regulation interventions have been the object of study due to their increasing evidence and association with health throughout life, social and educational aspects. Research shows that children who have experienced adverse experiences (for example, experiencing violence at home), tend to have deficits in self-regulation skills, therefore, it is important to delve into intervention processes. This research aims to analyze, through a systematic review with meta-analysis, following the "PRISMA" reporting guide, the interventions in self-regulation that have contributed to those children who experienced adverse experiences. The search in six databases, reflected a total of 6,854 studies of self-regulation and adverse experiences in childhood. After making a selection by reading titles, abstracts, 83 studies were selected for full reading, an analysis of quality and bias of randomized controlled studies and randomized controlled studies by groups, selected 41 studies for a qualitative analysis and 21 studies for meta-analysis, based on measures of heterogeneity between studies. The main results found are related to the type of intervention: interventions within the school environment, interventions based on electronic or computerized games, interventions focused on family support, interventions based on games or physical activities, such as yoga, mindfulness or some sport. Finally, the results based on the type of population that has experienced adverse experiences and the studies that work on self-regulation, limitations, and the implications of the results for practice, policy, and future research are discussed.

This dissertation aims at exploring the intrinsic characteristics of the Board of Directors, verifying the conformity of such boards with the stablished good practices of Corporate Governance while also exploring the Board Interlocking that exists in said boards with the help of Network Analysis. It also aims to map the shareholder composition of the studied companies composed by a sample of Level 2 of Corporate Governance of B3 from the year 2017. For that, we used a theory-based research in which he data collection in order to reach the objectives was achieved through a bibliographic and documental research. In order to analyze the networks of the Board Interlocking, we used the Gephi software to draw the networks of interest and make the measurements of Modularity, Intermediation Centrality, Degree Centrality and Proximity Centrality. The results regarding the characteristics of the Board of Directors shows board members with notable professional careers and academic legitimacy, little feminine participation and boards composed mostly by family members. The results regarding the conformity of the Board of Directors with the good practices of Corporate Governance show that the size of the boards to be in accord to the legislation, CEOs/Vice-CEOs holding also the positions of Chariman/Vice-Chairman and once more the issue of family members with control of the board composition. Last, the results for Board Interlocking, one research showed that 80,9% of the board members of the analyzed companies were interlocked, meaning that they participated in ate least two different boards, connecting the sample to other 789 organizations. Of the 20 companies, only 2 (AES Tietê and AES Eletropaulo) connected directly through the Board Interlocking. Another analysis assessed the inter-board Board Interlocking in which 14 of the 20 assessed companies had two or more board members acting together in another 46 companies not listed At the Level 2 of the Corporate Governance of the B3. A third analysis showed that a subset of 42 companies not listed at the Level 2 of Corporate Governance of B3 (from the total of 789) which connect 18 companies listed at Level 2 of Corporate Governance (of the 20), with the exception of Celesc e and Gol. A network analysis was made using Gelphi, identifying 5 clusters; AES Eletropaulo, AES Tietê, Marcopolo and Renova had a higher degree centrality and intermediation; ABDIB, IBGC, AMEC, AES Tietê and AES Eletropaulo had higher proximity indicator. We also gathered data for the shareholder position of the 20 companies, in which 7 of them share investors. This network was drawn in tandem with the third analysis to verify which factors could complement the corporate relations. The Board Interlocking proved to be, therefore, a primordial factor to the network analysis, specially by the fact that the Board of Directors has several members that provide a myriad of connections. For future works, taking the shareholders position, underlying questions could also be analyzed in order to make clarify the corporate ties and the complexity of the networks made by them.

As many aspects of education, teaching botany may not be easy due to several factors and awakening the student's interest in learning about plants can be very difficult. In this work we aim to help the teacher with support material so that he can present some plants in a different way, through cooking, with practical experiences, and showing students the wide variety of unconventional food plants that exist. The material has information on conventional food plants (PAC) and unconventional food plants (PANC), with a focus on PANC, where it will be possible to learn where to find, how to identify, how to collect, what are the benefits in food, forms of cultivation and examples of consumption. Videos of very practical cooking recipes were produced, which the teacher can make together with the class or take ready-made so that the students have the opportunity to taste. This support material can be used when the teacher starts to teach Botany or after the students already have knowledge about basic concepts, in that case, the material would offer elements that reinforce the concepts and help to have greater contact with plants.

In the field of soft actuators, ionomeric polymer metal composite like devices (IPMCs) are a trend, as they display great displacement when a low electric potential is applied. Its work mechanism is related to the migration of solvated counterions inside the polymeric membrane, so the type of counterion plays a key role in the IPMC performance, while keeping the membrane hydrated limits the usage of IPMC's in dry environments. Ionic liquids (ILs) are used in IPMC to solve the dependence of the environment, but with the burden of poor mechanical performance. Thus, the objective of this work was to study the electrochemical, electromechanical and thermal properties of Nafion®/Pt-IPMC with different counterions (H+, Li+, Na+ and [BMIM]+) and to tune the concentration of ionic liquid 1-butyl-3-methylimidazole chloride ([BMIM]Cl) with 0.1; 0.3 or 0.5 mol L-1, attaining electrochemical stability with better electromechanical performance independently of humidity level. [BMIM]Cl was successfully synthesized and characterized through Nuclear Magnetic Resonance, Infrared Spectroscopy with Fourier Transform and Cyclic Voltammetry (CV). IPMC electrochemical behavior was studied through Electrochemical Impedance Spectroscopy, CV and Chronoamperometry, while the electromechanical properties were measured through blocking force and displacement, and mass loss with Thermogravimetric Analysis. IPMC-[BMIM]Cl tests were performed in distinct humidities (30%, 60% and 90%). Concentration of 0.3 mol L-1 provided electrochemical stability with the best electromechanical performance regardless of relative humidity. This result will be important for enhance the devices performance and efficiency.

The Civil Construction Industry is characterized as a sector with a complex production flow. The diversity of stages, even in small projects, produces a large informational input that, based on the current model for organizing and managing project information - based on 2D - has the potential to generate divergences, omissions, duplications or project doubts that reflect in production stages. Besides the lack of integration and communication of the current structure that can drive delays, additional costs and production errors throughout the life cycle of a construction project. Therefore, Lean Construction and Building Information Modeling (BIM) have the potential to solve some of the most recurrent problems in the Architecture, Engineering, Construction and Operation (AECO) industry. Thus, this paper aims to analyze the main Lean Construction tools that contribute to the conduct of construction processes and can be catalyzed through the BIM methodology. To this end, a Systematic Literature Review (SLR) was conducted in order to collect the main concepts and conclusions already existent on the proposed theme and a Case Study was analyzed in the execution phase of the Last Planner System (LPS) and prefabricated systems, and such implementations converge with the Lean Construction principles. From the RSL, it was possible to conclude that BIM can act as a Lean catalyst methodology due to its collaboration, coordination, facilitated communication, 3D visualisation and 4D simulation functionalities, improving the processes conduction and the product result. In this context, a BIM implementation proposal was carried out with the objective of catalyzing Lean Construction in the Case Study.

Deep Learning has achieved state-of-the-art results in several domains, such as image processing, natural language processing, and audio processing. To accomplish such results, it uses neural networks with several processing layers along with a massive amount of labeled information. One particular family of Deep Learning is the Convolutional Neural Networks (CNNs), which works using convolutional layers derived from the digital signal processing area, being very helpfull to detect relevant features in unstructured data, such as audio and pictures. One way to improve results on CNN is to use regularization algorithms, which aim to make the training process harder but generate models that generalize better for inference when use in applications. The present work contributes in the area of regularization methods for CNNs, proposing more methods for using in different image processing tasks. This thesis presents a collection of works developed by the author during the research period, which were published or submited until present time, presenting: (i) a survey, listing recent regularization works and highlighting the solutions and problems of the area; (ii) a neuron droping method to use in the tensors generated during CNNs training; (iii) a variation of the mentioned method, changing the droping rules, targeting different features of the tensor; and (iv) a label regularization algorithm used in different image processing problems.
A Festa de Santos Reis como resistência da cultura caipira no bairro rural dos Camargos em Juquitiba-SP

With a focus on understanding the resistance of caipira culture, a case study was conducted in the Camargos neighborhood, in the municipality of Juquitiba-SP, registering the population’s way of life and especially the performing in the Three Kings’ Day celebration. The municipality has a socio-spatial formation that is historically connected to the formation of rural neighborhoods with the development of caipira culture in the 19th century. Along with urban expansion, caipira societies have undergone transformations regarding their working, leisure, and inhabiting dynamics. However, some changes have happened in a slow and fragmented way, considering that the municipality is still mostly rural, being requested as a spring protection area with decisive environmental importance. Our goal was thus to identify aspects of change and permanence essentially based on caipira sociability. For that, literature on this study area was used, as well as quantitative population and urban infrastructure data to measure the challenges found in these rural areas. Using a qualitative perspective, we adopted the oral history technique to get to know the reality experienced by the inhabitants of the Camargos neighborhood, grasping their memory and experience. Due to its environmental potential and to being part of the São Paulo Metropolitan Region, it was possible to register a dynamic of growth in the occupation by summer country houses. Within this complexity, the municipality of Juquitiba is also part of the Ribeira Valley and faces the tendency of emigration due to the low offer of infrastructure in the areas of health, housing, education, and quality of life, while the leisure use of these places grows. Contradictorily, this dynamic can offer employment alternatives for the population, ensuring their permanence in rural neighborhoods. The passage from a subsistence economy to the service sector has kept a way of life that is connected to the land, with flexible time and relative autonomy regarding the religious practices of popular Catholicism. The structure found in family and neighborly-based neighborhoods, in its turn, gives rise to a dense network of communitarian relationships, be it at work or in religious manifestations. Just as it was common in previous decades, it is possible to find elements of the caipira culture reframed and adapted to a new context. Due to the time-space fragmentation, different temporalities coexist in the same space, being expressed at work, in habitation, in the way of dealing with the environment and with the social life. Among the materializations of this way of live, we registered the Three Kings’ Day celebration, which, with its symbolism, reinforces neighborly bonds and affirms the territoriality of the neighborhood life, alluding to the church, the family, and the property, seeking the permanence of its celebration goers for the following years. The celebration outlines the desires of the group, which not only wishes to reach grace through the divine, but to reestablish their contact with collectivity and to reproduce the community spaces of peasant life. Devout celebration goers transport the desires of being, standing, and producing a space, seeking permanence and the symbolic appropriation of their territory.

Citrus canker causes a decrease in the productivity and quality of citrus fruits due to the lack of efficient control and eradication measures and is caused by the bacterium Xanthomonas citri subsp citri (XAC). In proteomics studies previously carried out by our research group, the involvement of xylose metabolism, a carbohydrate present in the plant wall, in the bacterial infection process was bserved, demonstrating that studies with XAC may have biotechnological importance for the use of plant biomass. The objective of this work was to characterize the XAC xylulokinase (XK) gene, one of the enzymes belonging to this metabolic pathway, responsible for the phosphorylation of D-xylulose [produced from xylose by xylose isomerase enzyme (XI)] to D-xylulose-5-phosphate, then allowing xylose to be metabolized via the pentose phosphate pathway. There are two ORFS present in the XAC genome annotated as coding for XK (XAC1775 or xylB1 and XAC4244 or xylB2), and the alignment of the two amino acid sequences revealed only 26% similarity between them. These two genes annotated as coding for XK were used in the construction of an IPTG-inducible heterologous expression system to evaluate their predicted activities. The expression of the xylB2 gene returned an insoluble protein, and studies with xylB1 continued. Enzyme activity studies demonstrated that xylB1 encodes a functional xylulose kinase enzyme, and kinetic studies revealed the value of the Michaelis-Menten constant (Km) to be 0.7947 ± 0,4032 mM and the value of Vmax to be 0,01217 ± 0,001130 µMol of xylulose.min-1.mg of protein-1. In a Pull-Down assay to investigate possible XK interacting proteins, the results indicated absence or undetectable concentrations of proteins from the total cell extract that interact with XK of XAC. An attempt was also made to obtain a mutant strain deleted in the xylB1 gene, based on a double homologous recombination methodology, with the construction of the suicide vector (pNPTS138_ xylB1) with the in tandem cloning of fragments 1 kb upstream and 1 kb downstream to the xylB1 gene. So far, a heterogeneous colony was obtained, possibly containing the wild and the mutant strains (mutant to be named XAC∆1775), which is in the process of isolation of the mutant for further characterization against the wild strain regarding its pathogenicity. Given the importance of xylose metabolism within the current economic-strategic context of using plant biomass, this work aims to add knowledge about this metabolic pathway in XAC and is a pioneer in the molecular characterization of the xylulokinase (XK) gene in the genus Xanthomonas.

Several studies show that the many different situations of violence are considered a serious public health issue. Among the violence types that exist, the one against women, understood as gender-based violence, is considered a universal problem, regardless of the country's culture, level of education, religion, socioeconomic status or level of development. In this sense, this study focused on gender violence, based on the narratives of the women interviewed, seeking to understand the stories and experiences of women in situations of violence, and paying special attention to the role of the care network that assists women in situations of violence. This is a qualitative and exploratory study, carried out through interviews with women who have experienced domestic violence, all of whom are treated at a Specialized Reference Center for Social Assistance (CREAS) in a city in the countryside of the state of São Paulo (SP). The results show that women suffered all types of violence, ranging from humiliation to deprivation of freedom and food, verbal, psychological and physical aggression, among others; not counting on family and community support to deal with the situation and showing insecurity to trust the professionals and services of the care network that answers to women in situations of violence. In conclusion, it is necessary to discuss and think collectively about more effective actions and strategies to provide attention, prevention and recovery of gender violence victims, based on a network that, in fact, is supportive and assists women throughout their journey seeking help.

The outbreak of COVID-19 caused by the new coronavirus (SARS-CoV-2) has led to the confirmation of numerous cases and deaths in a short time worldwide. In March 2020, the World Health Organization (WHO) declared the new coronavirus a pandemic and from there, an effort by countries began to try to contain the spread of the virus. Of the measures taken, social isolation was the most effective, so far, being adopted both in Brazil and in other countries. Through social isolation, there was a change in people's behavior and habits, when they had to study and work at home by digital means. Federal Universities, in view of the scenario caused by the COVID-19 pandemic, established the suspension of face-to-face classes, as well as extension projects. In this way, teaching activities underwent changes in remote formats, as well as community service through extension and research projects. The objective of this study was to understand the perceptions of students from an Occupational Therapy undergraduate course at a Federal University in Telehealth in a University Extension Project. Based on this pandemic scenario and the adjustments for telehealth, the expected results in this research sought to understand what was the impact of this form of service for the formation of the student, what were the difficulties faced by them and to map their implications within the formation of undergraduates in the Occupational Therapy Course. The results that were found after data analysis were the following categories and thematic units respectively: Changes in Learning Processes (Challenges and development of new skills, Adaptation to remote care, Changes in student routine and Development of clinical reasoning); Differences in Health Care (Flexibility of strategies, Participation and bonding, Physical and social distancing, Understanding of everyday life and Use of technologies); Call center: how do I understand this strategy? (Continuity of Care), Social Isolation and Difficulties in the Teaching Activity (Use of technologies and digital tools, Bonding, Routine and Search for knowledge); Teaching Strategies (Learning Development); Guidance Material, (Contributions in the learning process, Use of Materials Produced); and, finally, Strategies and Difficulties in Telehealth (Strategies and Difficulties, Adequate Space, Technologies and Digital Tools, and Distance). Teaching and care underwent changes in their processes that generated great potential despite the challenges faced. Dealing with internet access problems, inadequate work and study space, new ways of evaluating and studying were just a part of what was built, but everything is opposed to the exchanges generated, the development of learning and the pro-activity of the students, as well as as the continuity of care provided to users with the flexibility of intervention strategies.

In this study we investigate João Antônio's literature from a specific interpretation of the essay “Dialética da malandragem”, by Antonio Candido. We suggest that if, in addition to a division between poles, in which obedience to laws and customs is considered as a line that separates order and disorder, dialectics can also understand a social logic that divides the country into hierarchical classes among themselves, it will be possible to notice in his texts the literary representation of a system that naturalizes violence and impossibilities, in the mold of a country project that wants to be advantageous for the few and adverse for the many. What we are indicating - which also involves the notes of the "Dialética da marginalidade" - is a conception that starts from the point of view of João Antônio's own characters to try to understand how this specific logic of inequalities affects the texts of the author, who was notable precisely for the interpretation of the Brazilian popular classes. It is as a synthesis of this literary analysis and its probable correspondence with the concrete life of the country that we name the model as the dialectic of social impossibility. It is a proposal that begins with Candido's analytical method and is structured on the perspective of these characters to identify the mechanisms that try to define their place in the world, which meticulously seems to intend to bequeath them violence, impossibility, and abandonment. In view of this, in this study we focus on the known fictional texts by João Antônio, prioritizing those in which the popular classes are markedly addressed and in which the author privileges the figure of the malandro and his contacts with small bandits. Thus, our corpus of analysis is composed of eight short stories from the book Contos reunidos, which brings together all the author's fictional production. Our hypothesis suggests a new debate regarding the work of João Antônio, indicating that it should be seen as the literary representation of the functioning of the social structure organization that affects concrete life of people and classes in the country.

A questão agrária brasileira é marcada pela subordinação da agricultura à lógica do capital, com sua tendência à concentração da propriedade da terra e dos meios de produção. Nas décadas mais recentes, a hegemonia do agronegócio no rural brasileiro alterou padrões anteriores de acumulação de capital, todavia, nossa hipótese é que o poder econômico e extraeconômico do agro latifundiário no país é um elemento estrutural e estruturante da (e na) questão agrária brasileira, notadamente pelas imbricações que se estabelecem, pacífica ou coercitivamente, entre economia e política. Dito isso, o objetivo desse artigo é evidenciar que, mesmo passível de alterações na aparência, o agro latifundiário brasileiro mantém, dialeticamente sua essência no processo de acumulação ampliada de capital, por meio de sua capacidade – legal ou não – de apropriação privada e concentrada da terra e de fundos públicos. Configura-se assim, como buscamos demonstrar ao longo do trabalho, uma dinâmica que, mesmo apresentada como síntese da modernidade, se sustenta pela força econômica, política e coercitiva que a propriedade da terra confere a uma determinada fração da classe dominante.

The Stochastic Differential Equation models (SDEs) assume an important role in finances. The major part of these models try to help the investors with the risk management of the financial activities and they use SDEs for describing the evaluation of certain variables such as the price and the volatility of assets. In this sense, one of our goals for this dissertation is to study how the financial market works, with special attention to option price and hedging strategies. The second goal is to show the mathematical modeling process with SDEs and, then, explore the models as Black - Scholes - Merton and it version with many assets. Finally, we conclude by presenting applications in real data and some possibilities to extend the option price models.
