    We start this work by recalling a class of globally hypoelliptic sublaplacians defined on the N-dimensional torus introduced by Cordaro and Himonas in 1994 and studied by Himonas and Petronilho in 2000. We consider a new class of sublaplacians that generalizes this one and prove that it is globally {omega}-hypoelliptic if and only if the coefficients satisfy a diophantine condition involving a new concept of simultaneous approximability with exponent {omega}. We also recall the Petronilho's conjecture (2006) for the smooth hypoellipticity and present a new class of sublaplacians for which the Petronilho's conjecture holds true in the ultradifferentiable functions setup. Motivated by the works of Petronilho and Zani (2008) and Chini and Cordaro (2017), we considered a vector field in the 2-dimensional torus with constant and real coefficients and we analyze the hypoellipticity and the solvability of this vector field when it is perturbed by a negative-order pseudodifferential operator. We find a non-negative order \sigma_0 such that for all operators with order less than to \sigma_0, the perturbed operator preserves both the global hypoellipticity and the global solvability of the initial vector field. This study was done in both the smooth case and the Gevrey case. Finally, we generalize, for a particular class, the work of Petronilho and Zani for the N-dimensional torus. Our study was motivated by the study of the Gevrey solvability of perturbations by Gevrey functions of the vector field system given in the first level of the complex studied by Bergamasco and Petronilho (1999).

    Arterial stiffness measurement, evaluated by pulse wave velocity (PWV), is a predictor of cardiovascular events. Among the main factors that affect arterial stiffness are cross-sectional area, medial wall thickening, wall-to-lumen ratio and collagen density. Recently, a device using finger-toe pulse wave velocity was validated for humans study, but to better understand the mechanisms that change arterial stiffness, it is necessary to use the arterial vessel for genic, proteic and histological analysis. Therefore, a new device – popmètre® – was designed for measurements of PWV in animals and it was not validated yet. The aim of this study was to evaluate the validity, reliability and objectivity of a new device pOpmètri® 1.0 for animal studies. Forty-two Wistar rats were allocated into 3 groups of different ages: Young: 1 month; Adult: 4 months and Older: 12 months. Two photodiodes were positioned on the right thoracic and pelvic members for PWV measurement, on anesthetized rats. Then, aorta, carotid, femoral and renal arteries were extracted and prepared for morphometric and histological analysis (cross sectional area – CSA, wall thickness and collagen density). Results of PWV and vessel structure were then correlated using Pearson correlation test (p<0.05). As expected, PWV was 46% higher in adult rats compared with young rats and 20% higher in aged rats compared with adult ones. Cross sectional area was significantly higher in aged rats compared with young rats in aorta (+151%), carotid (+94%), femoral (+62%) and renal (251%) arteries. Wall thickness was not altered among groups. Also, collagen density was higher aged rats compared with young rats in (aorta: 276%; femoral: 290% and carotid: 234%). A significant correlation was observed between CSA and PWV in all arteries: aorta (r=0.5642; p<0.001); carotid (r=0.6854 p<0.001); femoral (r=0.6642 p<0.001) and renal (r=0.7817; p<0.0001). Wall thickness did not correlate with PWV. In addition, collagen density correlated with PWV in aorta (r=0,8854), femoral (r=0,9031) and carotid (r=0,9051). The results of this present study allow us to suggest that PWV measurement, obtained by a new device pOpmètri® for small animals, was able to detect age-related vessel structure in rats. The device was approved of tests of validity, reliability and objectivity.

    The main objective of this study is to evaluate the impact of rural pensions on the reduction of poverty in rural areas of Brazil in the period from 2004 to 2015. Currently, more than 70% of total benefits issued by the Social Security Rural are pensions worth 1 minimum wage. This benefit corresponds to the pension received by the special insured persons, whose access to the benefit is granted by proving the exercise of rural activity. Special insured persons are rural workers who carry out their activities under the family economy regime. In order to carry out the present study, the influence of income growth and inequality reduction on poverty reduction was verified. After this initial analysis, the per capita household income (RDPC) of the rural households analyzed was broken down into 8 income sources. Then, the role of each source of income in income growth and in reducing inequality was verified, with a priority focus on the source of income related to special insured pensions. The analyzes were conducted for two groups: rural households in general and households with at least one special insured beneficiary of retirement. The results indicated that income growth had a decisive impact on the poverty reduction of the two groups analyzed. For rural households in general, at least 79.3% of poverty reduction was driven by the growth of the RDPC. Similar situation was observed for the group containing only households with at least one special insured beneficiary of retirement, where it was verified that the contribution of the growth of the RDPC was at least 73.7%. Decomposition and analysis of the RDPC revealed that for rural households as a whole, special insured pensions accounted for approximately 29% of RDPC growth in the period under analysis. For households with special insured beneficiaries of pensions, this source of income accounted for an even greater percentage of this growth, around 65%. The analysis of the impact of income sources on the reduction of inequality revealed a small contribution of the benefit of the special insured to the reduction of inequality in the rural households as a whole, so that around 4% of the reduction in the observed Gini index is associated with this portion of income. For households with special insured persons benefiting from pensions, the participation of the social security benefit in the reduction of the Gini index was substantially higher, approximately 54%. Thus, the presented results show that there is evidence of the performance of the social security benefit received by the special insured on the poverty reduction of the two analyzed groups.

    Throughout human history the consumption of natural resources has increased rapidly. The great leap happens at the moment we are inserted, the Third Industrial Revolution or Information Revolution - now highlighted by gadgets - of all order, such as smartphones, smartwatches, tablets, among others. There is continuous production of hardware and software, with direct impacts on the environment, economy and society, which characterizes the tripod of sustainability. According to the World Commission on Environment, Sustainability and Development, sustainability is defined as "meeting the needs of the present without compromising the ability of future generations to meet their own needs" (Amsel et al., 2011). In computational solutions, the impacts of the processes and methods used to design, deploy, and maintain them for sustainability issues are not usually measured by common development practices. Considering this problem, implying a lack of concern for sustainability in computational solutions, it is necessary to consider the issues of this scope, seeking direction solutions as suggested by the first great challenge for the Human-Computer Interaction area in Brazil (GrandIHCBr) - "Future , Smart Cities and Sustainability" (Neris et al., 2012). From this scenario, this research seeks to provide guidelines that help the team involved in the project to evaluate aspects of sustainability in computational solutions. The work started from a survey of the literature and a consultation to the computer community in Brazil that allowed to perceive the state of the art and the tacit knowledge in the subject. The literature also supported the choice of a reference model that was instantiated with the participation of 5 systems analysts and 3 researchers in computing. 21 directives were formalized. The directives were then presented to an industry professional and a university professor in computing for appreciation. The results suggest that the proposed policies can be considered as guiding factors for the design of computational solutions.

    The aim of the research, based on field research, is to understand how the translation phenomenon, presented in the retelling stories genre can estimulate the construction of children's identities. In other words, how the transition from a literacy event to another, grounded in the reading Children's Literature books, can contribute to the kindergarten children go through the oral and written language modalities in an attempt to read a book, interpreting, transforming, transcending, translating, venturing through multiple literary translation activities. The theoretical references of this work start from the idea of rhizomatic transversality and it is based on: 1) New Literacy Studies (BARTON & HAMILTON, 1998; KLEIMAN, 1995, 2002, 2007; MARTINS, 2007a, 2008; STREET, 2006, 2010, 2012, 2014) which investigates the conception of autonomous and ideological literacy models, literacy practices and literacy events, and discussing the importance of the genres of discourse and Children's Literature for the literacy and the development of language in its oral and written modalities; 2) Translation Studies (PAZ, 2009; LOTMAN, 1996; MARTINS, 012, 2013, 2018), which focuses in the concept of translation as creation and (de)construction, relating the translation to literacy practices as a way to enable the child to access the language in a competent and autonomous way, being a producer and consumer of texts; 3) Historical-Cultural Psychology and the Theory of the Activity (LEONTIEV, 1978a, 1978b, 2014a[1981], 2014b[1981]; VIGOTSKI, 2001, 2007; VIGOTSKII, 2014[1933]; VYGOTSKI, 1995[1931]) which examines the conceptions of the leading activity, zone of proximal development, higher psychological functions, affective-cognitive development, and cultural artifact; and 4) Critical Discourse Analysis (FAIRCLOUGH, 2001; MEURER, 2005), one of the cornerstones of our data analysis, which highlights the role of language in social transformation and allows us to analyze the relations present in the process of oral and written languages appropriation within a game of subjectivation and translation carried out by kindergarten children. This study is based on a qualitative-interpretative paradigm (BOGDAN & BIKLEN, 1994), participant (EZPELETA, 1984; ANDRÉ, 2005) and ethnographic perspective (STREET, 2010) and it investigates: a) how the transition from one literacy event to another and from the storytelling activity to a retelling activity, in which the child simulates a reading based on the adult reading activity, could contribute to the development of children texts producers and consumers; and (b) how literary translation activities can encourage the construction of children's identities. Thus, the results highlight the pertinence of literary translation activities in the sense of providing the transition of the child by the most varied discursive genres, establishing links between oral and written modalities of language; by considering child’s play as the leading activity in the affective-cognitive development that makes possible the child literary translation activities; and also, by enabling the child to enter the world of language subjectively and creatively, transforming it and transforming itself.

    The present work was devoted to the study of the images contained in chemical textbooks approved in PNLD-2015. It aimed to classify the nature of the images contained in the themes Solutions and Colligative Properties according to the categories proposed in the taxonomy of images proposed by authors of the area, in addition to classic themes of PNLD-2015. The theoretical framework was based on the Theory of Semiotics by Charles Pierce and the Triangle of Johnstone and Johnstone-Kiill. The results obtained in this work show the predominance of the use of inoperative photographs in the textbooks, being these linked to the text by means of verbal labels. The images favor the Macroscopic dimension to the detriment of other dimensions, weakening the understanding of chemical concepts at the submicroscopic level, as well as the low percentage of images and texts that deal with the History of Science, contributing to the conception of individualistic, elitist and perfect Science.

    This work consists in a contrast between the initial trajectories of two black authors of Trinidad and Tobago; C. L. R. James and Oliver C. Cox. The period of beginning is marked, in this research, from the birth of these authors until the publication of their magnum opi, 1938 for James and 1948 for Cox. The contrast was made having as its based a path opened by the Jamaican theorist Stuart Hall when he debated his trajectory, i.e., the idea of prism of Caribbean formation. It is argued, then, that the intellectual production of Afro-Caribbean authors may be read in the interstice between a flight from the dynamics of oppression inherent to a place of nonhumanity, the zone of Nonbeing, and the validation logics and horizons of possibilities reserved to black intellectuals in different national contexts. The magnum opi that marks this research’s chronological frame also denounces these dimensions through theoretical displacements that the authors have accomplished by a forced dialogue with Universalist Western intellectual traditions by which the authors they were formed.

    Opinions on the Web have been increasing progressively and, thus, has aroused interest in areas of study of Linguistics and Computation, for example. In this context comes the Sentiment Analysis, or Opinion Mining, which aims to analyze computationally opinions, emotions, feelings and subjectivities present in texts (LIU, 2012), however, certain subjective sentences can carry irony, transforming the meaning of a sentence. This dissertation aims to investigate expressions of irony in social media, focusing on the description of linguistic devices as clues of irony in opinion texts in Brazilian Portuguese. To understand the functioning of this figurative mechanism, we will start from the search a corpus constructed by new commentaries from the Folha de S. Paulo portal. In addiction, based on pragmatic and cognitive theories, we developed a corpus annotation scheme for opinions and their intentions: ironic, other types of irony or non-ironic. As a result, we have obtained a list of subcategories that characterize expressions of irony that allow to collaborate with the development of the NLP area and Sentiment Analysis and, in addition, to improve tools of automatic identification of opinion through the descriptions and the linguistic resources elaborated here.

    The Fontes do Ipiranga State Park (PEFI) is an Atlantic Forest Conservation Unit (UC) located in the city of São Paulo and has a unique feature: it houses several institutions in its interior, such as the São Paulo Zoo and the São Paulo Botanic Garden (JB), among others. The PEFI presents more than 210 species of vertebrates, however, much of this fauna is threatened by anthropic actions because it is inserted in an urban area. Some problems are: the risk of running over, electrocution, illegal hunting / capture and transmission of diseases and predation by invading domestic animals. Our main objective was to elaborate and apply a teacher education course, from a critical, emancipatory and transformative environmental education (EE) perspective, to two schools located around the PEFI, in order to identify the dimensions of the educational process, the dimensions of social learning (AS), in addition to the EE aspects. The research was developed in a qualitative approach, based on the presuppositions of action research. Thus, we signed a partnership with two state schools, one elementary school I and another elementary and secondary school, in which 47 teachers from all areas of knowledge participated. The research had a procedural character, being developed in four moments: the first consisted of a socio-environmental diagnosis with the participants; the second was the preparation of the course based on the diagnosis data, meeting all the demands of teachers and schools; the third time consisted of the application of the course, which had a total of 20 hours, being 8 presential and 12 at a distance, with development of EE activities in schools and student visits to the São Paulo Zoo; the last moment of the research was the analysis of the data and the course. As a result, we identify all dimensions of the educational process: the dimension of knowledge, ethical and aesthetic values and participation, the first one prevailing, but also the dimension of participation was well considered. As regards AS, its dimensions - reflection, communication, negotiation, action and participation - were also identified, which allowed us to relate both theoretical references in a critical EE perspective. Also with the course analysis, we could note that, although this was based on critical EE, the EE strand that was most identified in the course was pragmatic EE, which did not exclude the other strands and, in some aspects, the conservative and critical lines emerged. In this way, the training course addressed the main characteristics of effective continuing education courses, including, in part, pedagogical knowledge of content, active learning methods, collective participation, duration and coherence. Thus, we hope the course has contributed to the awareness of those involved, so that they become interested in the environmental issues of PEFI and become involved in the fight for the conservation of this UC.

    Phimosus infuscatus is a bird of gregarious behavior found in South America. Despite its conspicuity, few studies involve the species, so that a large gap exists on its ecology. There is, for example, no in-depth information on abundance in feeding areas, habitat selection, behavioral repertoire, roost use, daily dispersal movements, breeding and morphology of chicks. Thus, this study was developed aiming to verify the species abundance and habitat selection in foraging areas in three municipalities in the coast of Santa Catarina, presenting and discussing its behavioral repertoire; to analyze daily movements between feeding areas and a roost discovered in the municipality of Itajaí, SC; and to evaluate its reproduction during two seasons in two areas located in the city, with information on nest building, incubation, parental care, success estimates and morphology of nests, eggs and chicks. The research used binoculars, measuring equipment, meteorological databases, CEMAVE metallic rings for chick marking spreadsheets for data recording and computer software for organization, analysis and textual production. The abundance was related to the rice cultivation cycle in the region, mainly during soil preparation and inundation, and the reproductive period. The foraging was carried out preferentially in slightly flooded and low vegetation environments, with no major preferences between aquatic or terrestrial arthropods available as resource supplies, with food searching behavior considered the default. The roost was used continuously for two years, with daily movements of groups up to dozens of individuals and population fluctuation varying in the same way as the abundance quoted above. The species used rivers margins in two different models during its reproduction, with success as expected for the family, and better conditions in the second season, observed in the measurements of eggs and chicks, which allowed the definition of growth stages of the last. This study brings brand new information and serves for a better ecological understanding of the species, being able to contribute to preservation and management strategies, care of individuals in captivity and future research, also helping to understand the fast population expansion of the species in Santa Catarina.

    Production and distribution are two key decisions in supply chain management. In order to achieve an effective operational performance along the supply chain, it might be important for these two decisions to be planned in a integrated manner, especially in supply chains with low inventory levels between production and distribution activities. This thesis studies the integration of production, inventory, distribution and routing decisions in the context of furniture companies. Research involving this integration has focus on more theoretical and idealized scenarios and, therefore, analysis on real-world settings are scarce in the related literature. Thus, we contribute to the literature by proposing mathematical optimization models and solution methods to represent and solve the integrated production and distribution planning and scheduling problem in the context of furniture manufacturers. Moreover, we also highlight the advantages of integrating production and distribution planning and scheduling decisions over the current industry practice, wherein both of these decisions are made independently of each other. The proposed optimization models take into account features rarely considered in the literature, but commonly found in furniture companies, such as producing and stocking multiples components and sub-assemblies (instead of final products), sequence-dependent setups times and costs, different capacity vehicles performing multiples trips over the planning horizon, distribution routes extending over one or more periods, multiple time windows and customers deadlines. As a result, our models properly represent the real situation and can be used to support integrated production and distribution planning and scheduling decisions in furniture companies. These models, however, are difficult to solve and their use as a production and distribution planning and scheduling tool is limited to moderate sized instances. In order to solve larger problems, we also propose different decomposition-based heuristic methods, which are able to solve larger instances in reasonable computing times. Results show that our heuristics, based on mathematical programming (i.e., matheuristics), are able to produce better solutions than general-purpose optimization solvers in shorter computing times. Exact solution methods, based on Benders decomposition, are also proposed to provide better quality solutions for small instances. Computational evaluation of these approaches shows that they perform as well as a general-purpose optimization solver. Overall, the approaches here proposed (i.e., mathematical optimization models and solution approaches) can be used in different furniture companies, as they are able to effectively support production and distribution planning and scheduling activities, considering the most relevant and common features found in the furniture manufacturing and delivery processes. Moreover, these approaches can be adapted or extended to be used in other industries with similar production and distribution processes as those found in furniture companies.

    In Brazil, semi-deciduous seasonal forest (SSF) is one of the physiognomies of Atlantic Forests, and sited between the Atlantic Forest and Savanna Biomes. Over the last decades, SSF has been fragmented by use of the soil for agricultural or urban areas. The urban and industrial growth promote a strong impact in forest fragments due to the edge effects, isolation, and habitat degradation. Hence, the knowledge about ecologic dynamics and biotic integrity inside this fragment is essential to guide public policy and to support decision makers, in the planning and management of territories. The goal of this study was to analyze the Biotic Integrity in fragments of SSF inside Ribeirão Preto (SP), a medium-sized city in the southeast of Brazil, and to analyse the relationship between BII and landscape metrics (size, shape and connectivity). The method (BII) has nine indicators (littler and grass cover, stand of dead trees, exotic wood species, vines, gaps in the canopy, vascular epiphytes, later species in canopy and in understory). The results can vary from 9 to 45. The survey was carried out in 9 forest fragments, the sizes of which are from 1,3 to 185,0 ha, all with urban influence. The relation between IBI and landscape metrics (size, shape) were analyzed by the Pearson correlation. BII value were registered from 26,0 to 38,0 or as low, medium or high integrity. The results showed strong correlation between IBB and size (p= 0, 7944), and weakness with shape (p= 0, 47). Therefore, the results show a vast area (77 ha) with low Integrity and another small area (22 ha) with high integrity. It was registered a medium-sized area, with high integrity located urban area in expansion, for which it was recommended the creation of one Protected Area.

    Many studies have been carried out to find the best operating point for filter media, and the mathematical modeling and simulation are becoming a important tool. In this work, a code was built to generate geometric models for filter media from data obtained by statistical analysis and microscopic images, to be used in simulations. Two different approaches (random and uniform distributions) were used to alocate the fiber inside the limits of the filter medium. The OpenLB library, which uses the mesoscopic approach lattice Boltzmann method based on kinetic of gases, was used to calculate the gas flow and estimate the pressure drop through the filter medium. A free slip boundary condition was implemented in OpenLB code, using the mesoscopic approach of specular reflection of the distribution functions. This boundary condition was then applied on the fibers surfaces, with the purpose of correctly represent the slip flow regime. The free slip boundary condition was verificated by simulating flows in confined duct and around obstacles, and the results were compared with data obtained by macroscopic simulations carried out on the commercial package ANSYS Fluent, which solves Navier-Stokes equations, and also with data found in literature. In filter media simulations, the free slip and no-slip boundary conditions were applied on the fibers surfaces and the numerical results of three types of filter media were then compared to experimental data. A better agreement between numerical and experimental data was observed if the free slip boundary condition was used. This confirms the need to consider the proper boundary condition in flows with high Knudsen number. Moreover, an analysis of the influence of the size of the computational domain on the pressure drop was also carried out, in order to determine the smaller size of the geometric model of the filter medium. According to the results, the pressure drop tends to become stable with the increasing of the domain, since the solid fraction is more accurate. This stabilization occurs with better agreement when the ramdon alocation of the fibers are used to distribute the fibers inside the filter medium.

    Urban public green areas are public spaces with vegetation, free (total or partial) waterproofing, which perform ecological, landscape, social, cultural and recreational functions, among others, generating an increase in sociability, aesthetic, functional and environmental improvements in cities. In view of the benefits promoted by these areas, and considering the lack of privilege that the free spaces are approached in the planning and the lack of systemic perspective of them, the motivation of this research appeared on whether the public green areas are qualified for use; if there are relations between regions with more qualified areas and income; and how the population uses and perceives the importance of these areas. The general objective was the analysis and the relation between spatial distribution, functionality and attractiveness of people in public green areas in the city of São Carlos, SP. The paper was structured in three parts, with introductory elements in the first, development of two articles in the second and final considerations in the third. The first article analyzes the qualification of green areas for use, and their relation with the spatial distribution, vegetation concentration and income of the population. The second brings analyzes of uses, functions, and attractions, considering qualitative criteria and the environmental perception of the regulars. A bibliographic research, the use of geoprocessing tools, functional investigation forms and perception questionnaires were carried out. The results indicated 779 areas available for the leisure green area system, but 463 were considered only partly qualified for use. There was a greater amount of qualified green areas in higher income areas, and partly qualified and unqualified green areas in peripheral regions. There is attractiveness to the practice of physical activities, leisure, contemplation, well-being, commerce and work, indicating a potential for multiple uses of the public dimension. It is necessary that the management of green areas be integrated with urban planning, holistically and systemically designed to be part of the daily life of the city, and not only represent obligations of minimum amounts to create lots.

    With the dissemination of mobile devices and the migration of activities that were once executed only on desktop computers to smartphones and tablets, the concerns related to accessibility in this environments have increased. Accessibility barriers can directly affect the access of information: a user with difficulties on accessing important information can become frustrated, absorbing the content with difficulty or even not being able to assimilate any information. The difficulties encountered by a great variety of users on mobile devices adds new challenges to the task of creating accessible applications for everyone. However, the accessibility impact of mobile interface design patterns in the life of disabled people has not been widely addressed in academic works. At the same time, the community of mobile designers and developers has made significant advances in identifying accessibility issues with design patterns on mobile interfaces, reporting these findings in virtual spaces of discussions as forums and blogs. Against this scenario, this project proposes recommendations that will help to mitigate or eliminate the accessibility barriers created by Interface Design Patterns on mobile applications. These recommendations were created based on two main studies. The first study was an accessibility evaluation based on interaction design patterns in an e-learning application containing 21 participants without disabilities that collected the emotional response to seven design patterns and video analysis using communicability metrics. While the second study aimed to explore the experiences and knowledge of professionals through an ethnographic study in 18 virtual communities of mobile design and development with the goal of identifying issues on the accessibility of Android mobile interface design patterns. This work presents two main contributions. It presents an approach to support the employment of virtual ethnography studies in software engineering as means to observe software development practice based on the information available in online communities. It also proposes 22 recommendations of 11 Interface Design Patterns and 11 Cross-section elements of mobile applications with the goal of improving the overall accessibility of mobile devices.

    In the central region of the State of São Paulo, in the municipalities of Brotas and Itirapina, the Ecological Station of Itirapina (EEI, in portuguese) is located, which together with the Ecological Station of Santa Bárbara, presents one of the few places where one can observe areas of open phytophysiognomy of the Cerrado . The EEI is considered an important area for birds and biodiversity (IBA) due to the presence of migratory species, endemic and endangered species such as emas (Rhea americana). Previous studies have recorded small flocks of emas living in the EEI in the 1980s, but the presence and size of this population is currently declining. Thus, the objective of this work was to evaluate the situation of the american Rhea population in the EEI, to discuss the feasibility of reintroducing captive birds for the species reinvigoration, as well as the threats to this population and evaluation of the methodology used. For that, motorized transects, walking and fixed observation points were established as a strategy to detect birds. At the end of 13 months of study, more than 1,000 kilometers traveled and 162 hours of active search, 29 traces of footprints and three views of a single adult individual were recorded by the IEE inspection team. Considering the various references related to Rhea americana in the literature, as well as the results obtained in this study, it is believed that the emas population in the ISS is in a situation of great vulnerability, with strong evidence that there is only one individual using this conservation unit. Many factors directly affect the survival of the emas in the EEI and make it difficult to reinvigorate these birds. However, if we consider the various benefits of increasing the population of this species that, in addition to being threatened with extinction, also participates in the connectivity between forest fragments, increases the germination and dispersion of some large and medium sized seeds, as well as interacts with different chains food being prey and preying simultaneously, it is believed that it is highly beneficial to the entire local ecosystem to carry out an action of population reinforcement of captive emas in the Ecological Station of Itirapina.

    Social participation is fundamental to the control of state action, ensuring transparency to acts of Public Administration. Fiscal transparency is established for in Complementary Law 101/2000, ensuring transparency as a mean of control and inspection. The 12.527/2011 Law institutes as a fundamental principle that access to public information is the rule and secrecy the exception. Due to the importance of this theme, considering that currently the sharing of information occurs through the internet, this research aims to clarify the dissemination practices of information on administrative contracts in the portals of the federal universities of the Southeast region, which promote the strengthening of participation of the citizen and community. It seeks practices that go beyond the legal requirement, highlighting the best characteristics that portals must present for the availability and access to administrative contracts, emphasizing the importance of the availability of complementary information relating to contracts required for comparisons and various analyzes. In this exploratory and descriptive research, the content analysis method with the creation of a form for data collection is used to increase the possibility of discoveries during the research. The public administration is contextualized by means of theoretical reference, focusing on publicity and transparency of administrative contracts, on the structure of government portals and the availability of information relating to administrative contracts. The laws relating to administrative contracts, fiscal responsibility, corruption against public administration and access to information are presented. The results provide a scenario of how publicity of information on administrative contracts is being done in the portals of the studied universities, allowing the possibility of improvement in the method of availability and access of this information. Finally, in this process of public management, information management and public transparency, despite advances in the intention of transparency of public acts, it is understood that much must be done for efficiency to be achieved. It is considered fundamentally, as defined by the Access to Information Law, 12,527/2011 Law, that the Public Administration has to be proactive in availability of information regardless of requests.

    This work has as main objective to deal with the creation and expansion of isolated schools in the interior of São Paulo between the years 1889 to 1920 – the first 31 years of republic. The isolated schools were unidocent elementary education institutions that served at the same time and in the same space students of different ages and levels of knowledge. We understand that it was the economic development of the state of São Paulo started in the mid-nineteenth century - with the coffee-based agricultural expansion and accompanied by a railway network that linked cities and attracted a large population contingent – which made possible the emergence of a dynamic center in southeastern Brazil, especially in what we know today as Rio de Janeiro, Minas Gerais and São Paulo states, as well as the expansion of public schools in inland municipalities in the first decades of the 20th century. From this perspective, this period can be understood as a "watershed" in the organization of the free, secular and compulsory public education system. In these decades, schooling was, above all, part of a political program to solve Brazilian problems, so that it incorporated large sections of the population into the civilizing process. Political participation was linked not only to census voting but, to the process of schooling, however, this process already in the early years of the Republic did not mean a good school for all, especially in the state of São Paulo and to understand the expansion of elementary public schooling, it is necessary to understand the history of Brazilian education in the republican period, also understanding that the diffusion of the school groups was not established in a homogeneous, natural and linear way, as if we had first the isolated school that became schools reunited and sometime later the leaders realized that it was viable the transformation of these schools reunited in school group.

    To know the female situation and the gender relations in the scientific world contributes to the elaboration of strategies of shifts in the institutional structure of science. These changes are part of the search for gender equity in the academic setting. It is not just about increasing the participation of women in science and technology by increasing and stimulating access. It is necessary to recognize and unveil the sexist biases that are inherent to institutionality and are present among the lines of scientific culture, in search of the transformations of gender relations in science and technology, with the intent of keeping women in the academy and aiming at breaking the "ceiling glass". Thus, this descriptive and exploratory work aims to construct indicators of the participation of female professors in science and technology in a public institution of higher education and research and is guided by the following question of research: how to configure the distribution of female scholars in the scientific community of UFSCar in areas of knowledge, hierarchy and scientific leadership in the year 2017? We sought to identify indicators of female participation in the teaching community of the Federal University of São Carlos (UFSCar), referring to the year 2017. Documentary sources such as institutional reports, the Lattes Platform and the Directory of Research Groups of the National Council of Scientific and Technological Development (CNPq) were used in the research. The data portrays the participation of women in the teaching staff, the leadership of research groups, in the approval of research productivity grants from CNPq and in the exercise of trust functions. In order to analyze these data, the theoretical framework addresses the literature on gender and science derived mainly from Social Studies of Science.

    Many people who assist their dependent elderly relatives have trouble finding the time and energy for activities that are important for their mental health. In this study, a model was proposed to indicate skills that may affect a caregiver’s ability to establish plans that are important to their mental health and well-being, such as metacognitive skills (monitoring and self-regulation), social skills, and the ability to establish viable goals. Interviews were conducted with 30 caregivers, including 28 women and 2 men, with an average age of 57.5 years (SD = 11.09), concentrated in socioeconomic classes B and C, and who resided in the interior of the state of São Paulo. The participants responded to the following instruments: open questions about planning adjustments in care routines, Social Skills Inventory for Caregivers of Elderly Family Members, a Life Plans register, Zarit Burden Interview, and Beck Depression Inventory II. The results showed that caregivers own socioemotional wellbeing and the elderly person’s health were constantly monitored by the caregivers. To handle demands related to the caregiving context, about two-thirds of the caregivers enlisted the help of family members, friends, and professionals. However, half of the caregivers reported managing new or unexpected demands on their own, and this was often their only strategy. With respect to their social skills, the caregivers reported having a good repertory of skills, with their greatest strength being affective expression. More than half of the participants reported light to moderate perceptions of burden and depressive symptoms. In terms of their plans for the future, the caregivers mentioned more plans related to health and leisure activities. Eight categories were developed to capture differences in the quality of the plans. Plans for the maintenance of valued activities were most frequently mentioned, followed by plans that were classified as vague, and then viable plans. Scores for each factor of the social skills, burden and depressive symptoms measures were then correlated with the number of plans in each of the eight categories. Assertive Communication skills were positively related with the number of Viable Plans (r = .38, p = .04), the number of Vague Plans was positively related with perceptions of burden involving Emotional Tensions (rho = .39, p =. 03), while the number of Plans being Implemented was negatively related to Emotional Strains (rho = -.41, p = .02). Thus, in consonance with the proposed model, in this study, there is some initial evidence that metacognitive abilities and social skills may be important in the process of constructing viable plans for the future, which, in turn, seem to affect caregivers’ mental health. If researchers continue to find evidence in support of this model, these concepts can be used to develop and evaluate interventions to help caregivers make better use of skills that can improve their ability to construct viable plans, which may contribute to reducing perceptions of burden and the experience of depressive symptoms.
