In the last decade, mobile applications have gained widespread use through smartphones, it has radically transformed the way people can access and use the media, bringing the internet and many everyday tasks in the palm of their hands. Such ease, however, brought with it new challenges, such as the need for devices with high energy efficiency, good processing capacity, performance, good ergonomic form, lightweight and easy handling. Despite the great efforts expended by all of these companies, some issues with mobile application classification are at the top of many developers' concerns, as implementation defects, lack of domain knowledge or even preparation for future functionalities can cause mobile applications to consume hardware resources incorrectly allocated to both the application user's need and the domain for which it was developed. Focusing on the identification of permissions' profiles, the correct use of resources and the way the application is implemented, this research proposes a method that involves Google Play Store data collection, to use techniques like clustering and visualization, which will provide to device manufacturers, mobile application developers, and researchers a simple way to compare and analyze mobile applications that use similar features. To evaluate the method, a case study related to the energy consumption of mobile applications was conducted, which proves its effectiveness in this type of analysis.

Carbon cycling of macrophytes in aquatic ecosystems occurs both by the characteristics of the environment (extrinsic properties) and by the different characteristics of their debris (intrinsic properties). So, in this study, you researched a proven carbon cycling of different initial Eichhornia crassipes debris compositions and humic material formations under the effect of increasing temperature on decomposition. A plant, inoculation material and incubation water were collected in the Barra Bonita reservoir in Barra Bonita / SP. Three types of experiments were performed that contain different initial compositions of macrophyte debris: (i) natural debris, simulating or newly added debris to the sediment; (ii) remove the aqueous extract, simulating debris after a few days of decomposition; and (iii) remove the alkaline extract, simulating advanced stages of decomposition. The materials were incubated for 120 days in anaerobic and aphotic chambers, at temperatures of 20 and 28 °C. A temporal variation of the mass loss caused by experiments, parameterizes the kinetic model using the Levenberg-Marquardt iterative algorithm, and is also calculated by coefficients Q10. The statistics employed follow a significance of 5%. By mathematical model adopted, higher values of mineralized carbon and wet material training were found without decomposition experiments, including natural debris and for experiments with debris without aqueous extraction, and the values of these fractions detected in this experiment may be affected by chemical use. the initial debris suffered prior to incubation. The refractory fraction was the main non-experimental component that only removes the aqueous extract. The more refractory to debris, the more transformations are necessary for it to be incorporated by the microbial community, as demonstrated by the parameterization of the mathematical model used. Decomposition coefficients (mainly refractory refraction) were more affected by quality than temperature increase, while Q10 values indicate higher sensitivities by temperature variation for experiments without water and alkaline extraction. On these evidences, the debris quality as well as temperature contributed to the increase in mineralization values. Mathematical modeling used in experiments clearly expressed as mineralization routes of different debris. Although the increase in temperature causes a mineralization process in the aquatic environment to be accelerated, the quality of the debris was more significant.

Teacher training is an important area of education and ultimately responsible for improving the quality of education received by students. The exercise of the teaching profession is full of intentionality and requires a deep knowledge of the dimensions that permeate the teaching and learning processes, namely, the human, technical and political-social dimensions. In this context, initial training is configured as a stage in the teacher training process that enables contact with different knowledge and discourses about education and pedagogical practice, guided by the National Curricular Guidelines for Higher Education Teacher Training (DCNs) and the Pedagogical Project of the Degree Course (PPC) where they study. At the same time, certain policies may contrast with the conception of education proposed by these documents, so that neoliberalism presents itself as an antagonistic political, social and economic model when looking at education from a market logic, neglecting its role in other spheres. Based on this, the This work aimed to collect the meanings of students completing undergraduate courses at the Federal University of São Carlos (UFSCar), Araras campus, regarding the role they attribute to the school together with their understanding of the teaching and learning processes, seeking to understand how such speeches and statements align or conflict with the DCNs and the neoliberal discourse. To this end, an online questionnaire and semi-structured interviews were used to capture the speeches that underwent subsequent discursive analysis, based on the Foucauldian framework, which sought identify in these speeches elements that highlight the construction of the subjectivity of these future educators in the context of initial teacher training, seeking to highlight the techniques of self and power responsible for modifying the experience that these individuals have of themselves and the world around them in these contexts. It was possible to verify the significant contribution of initial training in transforming the way in which undergraduates conceive the educational process and the role of the school and the teacher, in addition to revealing forms of resistance and opposition to the dominant discourse together with a deep knowledge and critical look at the challenges and the reality that the Brazilian educational scenario imposes, especially in relation to inequalities and school failure.

The advent of school inclusion brought the presence of deaf students to regular schools. In order to maintain quality, some measures had to be taken, such as the regularization of the profession of the educational interpreter, the professional responsible for mediating communication between deaf and hearing people. However, the Brazilian Sign Language, Libras, is very recent in our country, and several specific terms from the academic world are still not dictionized or are being created. Biology is one of those areas that, in addition to being full of specific terminology, has non-visible or even microscopic contents. Considering that the interpreter has a generalist training, we aim to find out what are the main difficulties they face when interpreting, as well as the strategies and resources they use to overcome them, together with professionals who work in high school. In this qualitative and exploratory study, we interviewed and analyzed the discourse of two educational interpreters regarding their practice during biology classes. The interviews were carried out at the Federal University of São Carlos. The analyzes were built through the presentation of excerpts from the interview, with theoretical basis in studies on deafness and education. The results indicate difficulties in relation to the partnership with the regent teacher, with the necessary adaptations for deaf students and also with regard to the lack of specific lexicon in sign language. Given the findings, we highlight some possible strategies, but we emphasize the urgent need for further research, involving deaf people and biologists, so that the area of biology can be studied in depth. Only with a refined linguistic repertoire in specific areas will deaf people have equal opportunities and access to knowledge as hearing individuals.

The present work has as its central problem the meanings of undergraduates in the initial formation in Physical Education about their educational curriculum, from the perspective of the theoretical framework of Cultural Studies in its poststructuralist version. Initially, there is a contextualization of higher education in Physical Education demonstrating its growth, as well as the expansion of this educational level in Brazil - with emphasis on private higher education. Language gains central prominence and it is from it that one explores the concept of culture and that of meanings. The methodology was based on two main moments: document analysis and semi-structured interviews with four graduates from two private institutions in the interior of São Paulo. The documentary analysis uses as a subsidy the Pedagogical Political Project of each institution in which the graduates studied were formed, as well as the analysis of the National Curriculum Guidelines of the Physical Education courses, which establishes directives to the training courses of this institution. modality. It is emphasized its importance in generating data for analysis, as well as to support the construction of the script of semi-structured interviews, for which graduates who work in the field of Physical Education degree were selected and, based on their speeches. , analyzed specific meanings about your training curriculum. Regarding the documentary analyzes performed, we discuss firstly the formation and identification of the authors; the strong concern with the practical issue of the course; the lack of specificity in the definition of the field and their expectations regarding the aptitude of the graduates to work in education. With the analysis of the semi-structured interviews, the meanings shared by the graduates reveal that the degree, in relation to the bachelor, is always allocated in a less prominent space; which has a close connection with the market logic propagated by the curricular organization - the appeals are always for the constant movement (of the students and graduates or the curriculum itself), to the lag and incompleteness of the initial formation. “Always” and for individualism (for merit or failure); culminating in what is conventionally called the Salvationist continuum. It concludes by pointing out the gaps of the initial formation, the preponderance of the market logic and the weakness of the subjects related to the degree.

The present work aims to analyze how the movie The Others (2001), by Alejandro Amenábar, integrates and modernizes itself on the Freudian concept of Uncanny in the cinematic tradition of the gothic. The Uncanny is part of a sensitivity core, something that is awakened on the individual something that is awakened in the individual when they are confronted with a situation that diverges from their conscious understanding of the world. Gothic art, by transposing into the environment the psychological and emotional state of the individual, transforms into Uncanny what was once familiar, becoming the genre that best suits the Freudian concept. In addition, the gothic is responsible for the reflection of social trauma, a repressed essence that returns after being left in the shadows.

This paper discusses the formation of the Brazilian Sign Language (Libras) / Portuguese Language interpreter, whose presence interferes with the psychological care provided to the signaling deaf patient in Libras. We analyzed the data obtained by the questionnaire, in order to score contributions regarding the role of TILSP in the health context. To carry out the work we brought clippings to illustrate our questions regarding mainly the formation of TILSP, as well as the emotional balance established within the therapeutic setting. However, the qualitative research was developed from the exploratory research methodology that according to Gil 2002, “Qualitative analysis depends on many factors, such as the nature of the collected data, [...], defining this process as a sequence of activities ”. Therefore, the work produced in addition to promoting the discussion of the formation of the TILSP professional in the health context, also aims to present some contributions about the role of the interpreter in the therapeutic context through the participants' reports. The work is organized in three main chapters in order to collaborate with the promotion of research that relates the interpreter of Libras in the context of psychology. Therefore, we identified that the participation of TILSP in the deaf community and deaf associations is indispensable. the search for complements in training. Finally, it is relevant that the professionals involved should qualify in order not to harm the main character who is the deaf person at any time, and should seek to improve their training in congresses, research area, articles, so that in practice can apply your knowledge and provide a better result of your work.

As birds are a well-known class of animals, occurring in almost all habitats, where they perform essential ecosystem functions, they are indicated as good bioindicators of ecosystem services (ES). Many services provided by birds arise through their ecological functions and their benefits are often transmitted indirectly, thus they are hardly understood or measured in terms of their contribution to human well-being. In this sense, this project aims to evaluate the relationship of the bird community with ES, not only the services promoted directly as birds, but also the ES of the environment itself that is related to its biodiversity. We selected 43 survey points distributed along riparian ecosystems, covering the entire Monjolinho River basin (São Carlos / SP), aiming to (1) analyze community structure in relation to the seasonality, land use and occupation influences, functional diversityand supply of ES; (2) to evaluate the seed disperser community with an improvement in the understanding of this ES provided by birds and its seasonal and spatial distribution in the study area; and (3) to investigate a relationship between bird richness and current state of ES as Cooling effect, air pollution retention and Nature-based recreation opportunities and their dynamic along an urbanization gradient. The results point to a well-structured community with 201 species and few seasonal variations, and remain with high richness at all points, even in urbanized areas. The functional diversity observed is linked to 8 ES types according to species’ ecological functions. The land use mapping showed a vast mosaic composed predominantly byanthropic areas such as agriculture and urbanization. The in-depth analysis of the seed dispersion ES, promoted by at least 39 species during two seasons, indicated significant changes in species composition and in taxonomic diversity and distinction between the rainy and dry seasons of the year, and higher quality of the dispersion service supply in environments with a higher proportion of native vegetation. The study over the relationship between bird richness and ES showed a significantly positive relationship between bird richness, air pollution retention and microclimate regulation, and negative with the recreation opportunities. These results can be used as a basis for better urban planning and for the definition of priority areas for environmental enrichment in order to expand the ES supplyas a guarantee of biodiversity conservation and increase in the human well-being.

Studies in Science, Technology and Society (STS) arose amid questions about the role of science and the use of technology in society, and its main purpose is to elucidate theories and methods that address the relationships between these three strands. One of the issues that raises the most concern in the scientific community, and affects society as a whole, concerns social and environmental problems, which are taking on increasing proportions even though there are legal provisions to mitigate them. In this arrangement of intense relationships, involving society and the environment, an important theory of the STS field arises that discusses the mutual influence exerted by human and non-human actors: the Actor-Network Theory, whose precursor is Bruno Latour. Supported by this theory and guided by the guidelines of a Brazilian Environmental Education program, this research proposes the formation of a network of social actors to face social and environmental challenges in a community in the city of Uberaba, located in Minas Gerais State, Brazil, in which society is invited to reflect on their reality and to act on relevant issues that impact its environment. The main objective of this study was to characterize the role of these actors in conducting the desired transformations, taking a close look at the organizational capacity of society during the confrontations. Based on the participatory action research methodology, network mediations were constituted by the stages of diagnosis, social mobilization and field intervention, involving community, schools, churches, universities, cooperatives, public authorities, among other agents. The results indicated that although society has the potential to overcome socio-environmental challenges, it is still unable to perpetuate the necessary transformations due to its dependence on government initiatives that, in turn, do not prioritize collective and participatory actions focused on socio-environmental confrontations. In addition, another aggravating scenario refers to environmental education, which is largely characterized by pragmatic actions, with little investment in actions based on critical thinking. In view of this, it can be concluded that although society is aware of the social and environmental challenges, its organizational capacity to face them requires, on the one hand, further dialogue between social actors and, on the other, educational processes that contemplate historical contexts about the social and environmental crisis and encourage the exercise of social control.

Shared attention (SA) is considered a milestone in child development. One of the most mentioned components in the literature for children starting SA is eye contact. The study of SA in young children with visual impairment is scarce and limited, suggesting the following questions: What are the behavioral dimensions of shared attention in the interaction between an adult and a young child with visual impairment? Is it possible to define theoretically and empirically what are the components of shared attention when the visually impaired child is involved in the interaction? To answer these questions, three studies were developed: the first aimed to characterize the components of shared attention of young children with visual impairment found in the definitions and in the method of empirical research conducted with this population. To achieve this goal, a systematic literature review produced between the 1980s and 2017 was carried out. The methodology used attended Preferred Reporting Items for Systematic Reviews and Meta-Analyzes/PRISMA requirements and resulted in 2,919 manuscripts survey theme of shared attention, 288 occurred with targeted participants by special education and 28 of them shared attention with visual impairment children. The result of the analysis of indicated studies addressed predominantly themes: definition of Shared Attention (N = 15); Limits of Shared Attention (N = 8); Maternal Interaction (N = 4) and Perspective Taking (N = 3). The main components highlighted in publications were touch/touch and communication when related to caregiver's interaction with the child. Many components descriptions of shared care found in publications about children with visual impairments brought difficult to identify and characterize the behavioral dimensions, especially components function indicated by studies. Therefore, Study 2 sought to empirically identify the behavioral components performance of initiating and responding to children with low vision in episodes of shared attention with an adult during free play. The study included 27 dyads (small and responsible child) recruited from an Educational Assistance Center Specialized in Visual Disability in Curitiba - PR. The instruments used were: Participants Protocol Characterization by Parents/Guardians; Brazil Criterion Questionnaire; Operationalized Portage Inventory; Transcription Protocols and Functional Analysis Protocol for Episodes of Shared Attention and analysis software adapted to OpenPose Realtime Multi-Person 2D Pose. The dyads were filmed in play situations for up to 10 minutes. The video recordings were edited with excerpts suppression from the beginning to the end recordings, totaling three minutes editing for each dyad. Videos descriptions and analyzes were carried out by completing the Transcription Protocols and Functional Analysis Protocol of Shared Attention Episodes. After observing and categorizing the SA behaviors in free inspection, video recordings were submitted to OpenPose programming treatment, in order to observe points of convergence between the guardian and the child in relation to the object and presented behaviors. The results indicated with the analysis using contingency of three, we have how much the OpenPose program was effective in identifying the SA behaviors of young children with low vision. Initiate a behavior SA most observed by those responsible were speech, hand movements and directives; for children and responding behaviors to SA were vocalization, conversation, responding orally and looking towards the source of the sound. The results presented by participants were in accordance with literature, as well as the result indicating that children were less likely to initiate shared attention. It is concluded that children components who shared attention with visual impairment are similar to those described for children in general. Additional research may help to refine the analysis procedures to advance the characterization of the phenomenon. In order to verify which components of initiating and responding to shared attention are presented by the child with low vision in a situation of structured activity, Study 3 was carried out: the participants in this study were 14 children selected from the 27 who undertook Study 2. The selection criterion was the child not to have completed four years and to be enrolled in the specialized institution. The instrument used was an unsystematic adaptation of Early Social Communication Skills - ESCS. The task materials that referred to shared attention were adapted/replaced by others with sound and light so that the children could access and carry out the activity. Original objective tasks proposed by the scale were preserved. Tasks were organized with reference to triple contingency. Results indicated that children with visual impairment had more behavior classes of responding to shared attention than of initiating shared attention. The ESCS behavioral observation protocol provided effective measures to identify SA components, as well as to verify children performance with low vision in tasks that evaluated the IAC and the RAC. Material adaptation and specific insertion components for SA behavior identification in children with DV were essential to obtain results. The thesis was concluded by stating that three studies contributed to describe shared care components with visual impairment children. Despite the effort to analytically break down aspects of shared care between the visually impaired child and their caregiver, it is necessary to invest in studies that detail and expand the findings of these studies. The lack of consensus in literature on shared care components, associated with conceptual problems and data collection methodological compatibility and analysis, limited discussion scope about this research results. Realization of other modalities of functional analysis, supplementary and complementary to those carried out here, may indicate new directions for consolidating behavioral components identification that establish the bases of shared attention in children with visual impairment.

We address the Constrained Guillotine Cutting Problems (CGCP) in this doctoral thesis. The CGCP consist of producing items from objects using guillotine cuts, i.e., cuts that divide the rectangular materials into two rectangular sub-objects without restricting the number of guillotine stages, and with a limitation over the maximum number of copies per item type to be cut from the object. New linear mathematical formulations are proposed for the Constrained Two-dimensional Guillotine Cutting Problem (C2GCP). The first proposed formulation is based on object discretization, which is also extended to deal with 2-staged and 1-group patterns, and a Benders decomposition algorithm is developed from it. Two other formulations are proposed to the C2GCP, based on the concept of successive combination of copies of item types and sub-patterns, i.e., the bottom-up approach; from the proposed additional constraints, these models strictly deal with d-staged cutting patterns, where d is a positive integer scalar. Two extensions of the C2GCP are also addressed in this thesis. The first extension is the Constrained Two-dimensional Guillotine Cutting Problem with Defects (C2GCP-D). The linear model and the Benders decomposition algorithm, both based on object discretization, are extended to deal with this variant, and then a new solution method based on Constraint Programming is developed. The second extension is the Constrained Three-Dimensional Guillotine Cutting Problem (C3GCP), which is addressed by models and by a tree-search algorithm. All these proposed approaches are evaluated through computational experiments, using instances of the literature or randomly generated ones, and compared to another approaches in the literature. Despite the applicability of these problems, the literature took more than three decades to present mathematical formulations to the CGCP. Therefore, this thesis contributes to new formulation paradigms for the CGCP and effective methods to solve them, which are competitive with those known in the literature.

Pneumococcus surface protein A (PspA) is a lactoferrin-binding protein that can be found on the surface of Streptococcus pneumoniae. The use of this protein as a carrier in the formulation of conjugate vaccines contributes to the protection against infections such as pneumonia, sinusitis and meningitis. Recently, the Butantan Institute developed a purification process for PspA4Pro produced by cultures of Escherichia coli BL21 (DE3) pET37b + PspA4Pro. Although the results achieved in terms of purity were satisfactory, it was observed a significant loss of the product during the purification, especially in anion exchange chromatography, the most expensive step in the downstream process. In this context, the present work aims to model and simulate this operation, developing an applicable methodology to model complex mixtures. In the first stage of this work, clarified cell extracts obtained from E. coli biomass produced under different cultivation conditions were purified. Anion exchange chromatography was performed on the Akta Avant 150 system and the samples were analyzed by Bradford methodology and band densitometry. The process was modeled by the EMSO software (Environment for modeling, simulation and optimization) and the modified Langmuir and the steric mass action isotherms were separately tested along with the equilibrium dispersive model to estimate the parameters and validate the models, proving to be adequate to simulate the process. The steric mass action isotherm was also used to simulate the chromatography of a virtual sample, with the parameters of PspA4Pro and the protein impurities separately adjusted. The simulation results were compared with the results of an experimental elution. In both cases it was observed that PspA4Pro eluted at the beginning of the peak, showing similarity between the simulation and experiment profiles and allowing to establish an alternative purification scheme that provided PspA4Pro at a purity of 82.8%, representing an increase of 34% when compared to the original purification process. In the second stage of this work, different experiments involving modifications in ionic elution forces and in the processed protein mass were tested on the column and a cross-validation methodology was applied. Simulations demonstrated that the chromatographic column could process twice the protein without loss of quality of the obtained PspA4Pro. These results were experimentally confirmed, providing a specific yield of 22 x 10-3 g PspA4Pro.mLresin-1 with purity of 81.2%, which was higher than the specific yield of 10 x 10-3 gPspA4Pro.mLresin-1 with purity of 73,9% obtained at the original process. In the last stage of this work, the cross validation methodology was once again used to separately estimate the PspA4Pro and the protein impurities parameters. The results of the simulations once again showed the tendency of PspA4Pro to elute at the beginning of the peak, but in variable profiles according to the applied ionic force, enabling the identification of alternative elution strategies. The best results were obtained by applying lower ionic forces, leading to a significant increase of purity (91.0%) without reduction of specific yield (9.7 x 10-3 gPspA4Pro.mLresin-1). The conclusions of this work show that it is possible to use mathematical models to describe chromatographic processes and to increase efficiency, even when complex mixtures are being processed, such as cell extracts with recombinant proteins. This approach facilitates systematic process analysis and allows a better understanding of actual purification operations.

In organizations, knowledge is already assumed as a strategic asset, as well as an explanatory variable for their performance and growth. Thus, it is considered that the diffusion and acquisition of knowledge determine the innovative potential of companies. In this context, this paper aimed to select the Absorptive Capacity (BB) Buildings Blocks (BBs) through the Systematic Review Literature (SRL) and validate them through econometric models for developing and developed economies. The research also identifies possible thresholds of these BBs using the fixed effects threshold model in panel data (2007-2015). The results show that BBs and their respective most significant thresholds for developed countries are not, in fact, the most important for emerging and developing countries, as groups have different socioeconomic conditions and therefore assume that each group has BBs that are more expressive.

The aim of this paper is to think about the ways in which it was possible to mobilize and adjust the workers’ subjectivity to the discourse and business literature taken as reference by the new forms of post-fordist management of the work. Through field observations, interviews with startups entrepreneurs located in coworking spaces and theoretical revision, we will try to understand how these new models of flexible work enable workers - especially those linked to the dimension of creative and immaterial work - to internalize discourses that connect their desires and affections to the dimension of the work. In this way, we want to 1st) demonstrate the convergence of the emergence of the first startup and coworking spaces, observing how, as a result, the coworking spaces collaborate to maintain the enterprising atmosphere of the startups and, 2nd) to answer in which ways the worker’s love in relation to the conditions and results of his work works as ideological “cement” for new forms of labor exploitation. In this exercise, we observe that the concept of alienation developed by Karl Marx takes on new dimensions from the mobilization of subjectivities, naturalizing the processes of expropriation and exploitation understood now as creativity and innovation. So bringing this whole context is important to understand the basis of our hypothesis today: the individual, a worker with flexible working models, does not consider himself disconnected from what he produces, but in other hand, he identifies himself so completely with his work that he ends up not knowing or even admitting the conditions of work to which it is subjected, in which daily days, weekly rest and personal life are subordinated to the needs of the realization of projects, in a daily life marked by instabilities, fragilities and precariousness. We work with the hypothesis that such subjectivity is related to a rationality where the worker becomes an entrepreneur and mobilizes their desires, affections and other subjective aspects in function of a higher productivity within the work. We understand that the spaces of coworking are privileged places to carry out the analyzes, since in these spaces we find a working model, as the startups, that are born from the economic and productive transformations and puts at stake a worker profile that, under flexible conditions of work, internalizes discourses and practices that increasingly blur the boundaries between his life and his work, thus softening situations of conflict and exploitation.

The low-pressure die casting process to produce automotive aluminum alloy wheels is well known, and, in the last decades, has been consolidated as the most common way to produce light automotive wheels in large scale. The big competitiveness in this market associated with higher levels of performance required, pushes the companies to seek for process optimizations and cost reduction. In this project, different regions of aluminum alloy wheels, casted in A356 and solidified at different cooling rates, were assessed in terms of its mechanical and microstructural properties in different steps of the manufacturing process, from as casted condition until final painted wheel; the impact of different periods of solution treatment as well as the effects exerted by the painting ovens on these properties were also evaluated. A great reliance was observed between the mechanical properties obtained and the primary and secondary microstructural refinement degrees, similar regions such as the outer and inner flanges of the wheel, cooled at similar rates and, with almost equal refinement degree and SDAS values, have shown practically the same results of elongation and mechanical resistance on all process phases evaluated. Inferior values of elongation and mechanical resistance were found for the wheel spoke, mainly due to its less refined as cast microstructure solidified at lower rates. The solution treatment was found a key process phase in order to transform the Si for the wheels to achieve minimum values of elongation, and the ageing treatment allied with the painting ovens has given the necessary resistance for the product to be applied in the field. The results found delineated a general process panorama and might be used for actual and future manufacturing process optimizations.

Several laws, at national and state scope, have been instituted for environmental assessment aiming at reducing the damage resulting from the replacement of native vegetation by anthropic agricultural and non-agricultural areas, as well as the obligation to recompose deforested areas. This study analyzed the effectiveness of the legislation and environmental inspection of the State São Paulo in relation to the assessment, prevention and recovery of environmental damage, within the territorial boundaries of 23 municipalities of the Central Region of the State São Paulo, based in a quantitative inventory of the Environmental Infringement Registration (EIRs) and Environmental Recovery Commitment Terms (ERCTs), drafted over the 31-year period (1987-2018). A total of 1,863 EIRs and, respectively, 1,207 signed ERCTs were quantified, with 61% of EIRs related to legally protected areas categorized as Permanent Preservation Areas. In the period from 2008 to 2018, a total assessment area equivalent to 1,753.05 ha was estimated, of which 1,107.71 ha covered with native vegetation; 65.92 ha sent for regularization via environmental licensing, and 664.53 ha related to native vegetation recovery procedures based on signed ERCTs. The municipalities considered potentially susceptible or critically compromised due to the higher values of EIRs and assessment areas (ha) were, respectively, São Carlos (188; 490.31 ha), Ibitinga (90; 301.62 ha), and Araraquara (85; 100.44 ha), over the 10 year period (2008 - 2018). In a potentially susceptible opposite situation, the municipalities of Bocaina (2; 0.18 ha), Águas de São Pedro (4; 0.68 ha), and Nova Europa (2; 0.99 ha) were identified. The increase in Gross Domestic Product values, and the change in land use related to increases in agricultural anthropic area and native vegetation area were pressure vectors directly related to the number of EIRs registrations, over the 31-year period (1987-2018). The number of environmental enforcement agencies in the study area did not directly influence the number of EIA registrations.The results obtained highlight the effectiveness of environmental legislation in its satisfactory regulatory capacity, with reference to what is real and true, with concern to the EIRs and ERCTs quantifying, within the territorial boundaries of the 23 municipalities of the Central Region of the state of São Paulo, over the 31 year period (1987-2018). It also indicates that the improvement of environmental inspection procedures inhibits the occurrence of new damage, as an essential tool for the effective control of deforestation and the recovery of environmentally degraded areas.

This work presents the reality of the education of indigenous deaf people from a Pankararu ethnic community, located in the interior of the state of Pernambuco, based on interviews with two deaf people and their families. We discussed, from the reports of family members and the difficulty of interviewing the indigenous deaf students themselves in LIBRAS, how education for these students has been proposed in the village (quite distantly from what is provided for by the legislation, specifically by law 10.436 of 2002 and by Decree 5,626 of 2005, which ensure the recognition of LIBRAS as a language and guarantee the access of deaf people to education). Questioning the ways in which the education of the deaf indigenous of this Pankararu community has been carried out, based on the studies of bilingual education for the deaf and the work of the professional translator and interpreter of LIBRAS in the educational sphere, we intend to highlight how much the training of professionals (including and mainly indigenous) in this sense, so that inclusive bilingual education can, in fact, take place within indigenous communities.

In Brazil, there are few studies that investigate the support needs of families that have handicap children in their daily context. There are few instruments as well that try to identify and evaluate the support needs level in the areas of family life that influence the family’s well-being in a certain moment of life. Therefore, the objective of this study was to perform the cross-cultural adaptation and the validation of the Evaluación de las Necesidades Familiares – ENF scale for the use with families of children and adolescents with disabilities. This is an instrument with the potential to help the families and their service providers to identify the needs and to make decisions that result in measures of support and quality of family life. To this end, two studies were performed: the first one was cross-sectional, multicenter and methodological of cross-cultural adaptation of the scale for its usage in Brazil. The second study was about the validation of the scale, which is also multicenter, cross-sectional, exploratory, descriptive and correlational, with a quantitative approach. The cross-cultural adaptation study was held in six stages (translation, reconciliation, back-translation, specialist’s evaluations, cognitive unfolding and pre-test) that resulted in a scale called Avaliação das Necessidades da Família – ANF in Portuguese, with 49 items and with an excellent index of internal consistency (Cronbach’s Alfa coefficient of 0.98). These items were obtained from analysis performed in the Software SPSS 21 version, with a sample of 38 families of children and adolescent with disabilities between 0 and 18 years old, residents in four Brazilian cities (São Paulo-SP, Santos-SP, Lagarto-SE and Maceió-AL). For the validation study of the Brazilian version of ENF two more instruments were used: the Escala de Qualidade de Vida Familiar (QdVF Brasil), used to verify the validation of criterion of ANF, is an instrument that has 25 questions that evaluate the family satisfaction in the last 12 months in a series of family activities; and the Questionário de Identificação da Família, that was made by the researchers to obtain the socioeconomic data of the participants. In this study participated 151 families of children and adolescents with disability, between 0 and 18 years old, residents in four Brazilian cities (São Paulo-SP, Santos-SP, Pelotas-RS e Maceió-AL), in which 130 of them were part of the main sample and 21 participated in the test retest. For the data analysis, it was used the Software R (The R project for Statistical Computing) 3.6.1 version. The structure of the scale validation process is indicated as valid from a structure obtained from the Structural Equation Modeling (SEM), that confirmed a final model for the ANF with 46 items distributed in seven dimensions (education, family life, community life, leisure time, economy, acquisition and management of products and services and health and emotional well-being) with a good index of data adjustment (RMSEA = 0.041 e SRMR = 0.063), satisfactory convergent validity (rs (130) = -0.27, p < 0,001) and excellent index of reliability obtained (Cronbach’s Alfa = 0.92 and McDonald’s Omega = 0.94) and reaffirmed by the test retest technique (R1F = 0.98). From the obtained results it can be said that the ANF is valid and trustworthy to evaluate the necessities of the Brazilian families of children and adolescents with disability under 18 years old.

The compliance with the Environmental Legislation during the implementation of Legal Reserves for the territorial limits of 23 municipalities located in the Central Region of the State of São Paulo, over the period of 35 years, was analyzed. The analysis was based on the development of a georeferenced database of Legal Reserves numbers and areas, between 1983 and 2013, under Federal Law n° 4.771/1965, and between 2013 and 2018, associated with the implementation of Federal Law n° 12.651/2012 and of the Rural Environmental Registry. The inventory of Legal Reserves numbers and areas, for the period of 1983-2013, was obtained from the consultation of the Integrated Environmental Management System (SIGAM), used by the São Paulo State Secretariat of Infrastructure and Environment (SIMA) for management and administrative proceedings. For the period of 2013-2018, the data were obtained from the consultation of the digital database of the São Paulo State Rural Environmental Registry System (SiCAR-SP). Between 1983 and 2013, 854 Legal Reserves with a total extension of 54,950ha were implemented for the territorial boundaries of the 23 municipalities in the Central Region of the State of São Paulo. Between 2013 and 2018 (September), a total of 4,550 Legal Reserves were potentially identified, equivalent to a total area of 146,444ha. Over the 35-year period (1983-2018), the São Carlos municipality had the highest number of registrations (524) and total area (22,208.04ha), while the municipality of Águas de São Pedro presented the smallest total area (24.07ha) and number of records (02) of Legal Reserves. The spatial cumulative scenario of the total areas of Legal Reserves in 2018, for the municipalities in the study area, highlighted São Carlos (30%), Ibaté (30%) and Trabiju (52%) with the highest percentages of municipality area defined as Legal Reserve, i.e., the municipalities that displayed the highest compliance with the environmental legislation. On the other hand, the Itaju (3%), Jaú (7%) and Bariri (7%) municipalities presented scenarios that were critically compromised with regards to the deficit of protected area in rural properties, due to the lower percentages of agricultural areas potentially protected in the form of Legal Reserve. An effective indicator for the government to act in relation to the fragility or administrative failure of these municipalities to comply with the environmental legislation. Although not all areas declared as Legal Reserves in SiCAR in 2018 represent a real implemented scenario, a potential increase of 432% in the number and of 170% in the extension area (ha) of Legal Reserves was estimated to Central Region of the State of São Paulo, between 2013 and 2018. These results show a trajectory that points to the increase in the amount of native vegetation in the study area, especially in terms of the number and extent of legally protected areas configured as Legal Reserves. This was especially true for the period of 2013-2018, when the values were more expressive, presenting a positive trend for regional environmental conservation. This research supports and highlights the effectiveness of environmental legislation, together with environmental enforcement, as responsible pressure factors in controlling deforestation and restoration of degraded areas of the State of São Paulo.

The objective of this work was to study the corrosion of AISI 1020 exposed in an atmosphere containing acetic acid (HAc) vapor. Electrochemical noise (RE) oscillations and surface micrographs of the samples were obtained simultaneously during the corrosion process for 2000 s. A potentiostat/galvanostat was used to acquire the RE signals. Two identical AISI 1020 steel electrodes were used as working electrodes and another AISI 304 steel electrode as a pseudo-reference. For electrochemical measurements, a sealed glass cell saturated with HAc vapor was used. The cell has a flat bottom which has been adapted in an optical microscope (MO) to obtain steel surface images at 6 frames/min rate. Atmospheres formed from solutions containing 0.0%, 1.0%, 50.0% and 100% (V/ V) HAc showed different types of corrosive processes indicating different corrosion mechanisms. For solutions containing 1.0% (V/V), 50.0% (V/V) and 100% HAc the current transient amplitudes were in the order of 9.2 pA, 50.0 pA, 62.0 pA and 57.0 pA respectively. The results were analyzed by Wavelet Transforms (TO) and the results were organized in an energy distribution diagram (EDP) where the energies are arranged in 8 decomposition levels (d1-d8). For atmospheric experiments using solutions containing 1.0% HAc the energy distribution is concentrated at the highest levels (d5-d8) where the process is characterized by localized corrosion. This information is confirmed by the images obtained in situ, which showed the formation of pits. The EDP data for the experiments performed from 50.0% HAc solutions showed a concentrated energy distribution at the ends of the diagram (d1 and d8). In this experiment, through the obtained images it is possible to notice that, after the steam condensation, there is a generalized corrosion formation on the electrode surface followed by the formation of corrosion products. However, in an exact simulation with the same conditions as above, the electrode surface was sanded and thus it was observed that pitting also occurred. Finally, experiments using 100% HAc solutions showed an increase in the concentration of the relative energy distribution at levels d1 and d2 and a smaller relative energy distribution for the other levels. In situ images show more intense corrosion after the initial 700 s of the experiment. With the successful analysis, localized corrosion and generalized corrosion were contacted. The use of the RE technique combined with TO and OM proved to be effective in a short time to evaluate and classify the corrosive process.
