The main objective of this study was to understand the contemporary regime of subjectivity in the favelas of Rio de Janeiro, based on the analysis of the processes that involve the pacification of these territories and the emergence of new forms of the market, having as empirical cut, the "tourist favela" and the "Self-management". The pacification project represented a possibility of political and economic management of certain territories chosen according to the strategic objectives defined by the power apparatus. Control, militarized surveillance and the consequent domestication of bodies can not be considered the only forms by which power invested, since pacification also sought to structure a field of action in which the favelado itself was an active subject of its own transformation by the way of entrepreneurship. In this sense, the study sought to understand the process of subjectivation of slum dwellers as something situated in the midst of a complex of apparatuses, practices, machinations and compositions within which they were constituted and which presupposes the implication of particular relations with themselves, the research analyzed how the intersections between a set of devices that propitiated a strategic articulation of the ways of conduct of others with the forms of self-government. In order to elaborate the study, the following areas of UPP were taken as object of analysis: Favela Santa Marta, Favela Pavão-Pavãozinho, Ladeira dos Tabajaras / Morro dos Cabritos and Complexo do Alemão. The methodology used for the purposes of the thesis could be fulfilled consisted in the elaboration of a study based on the qualitative analysis, obtaining data through direct observations and semi-structured interviews. As a result, it was possible to observe that the expansion of neoliberal logic in the pacified favelas, on the one hand, configured entrepreneurship as a possibility for the favelados to find their "place in the sun" and on the other intensified processes related to the individualization of destiny and poor subject, as well as the emptying of the public sphere and collective projects.

Fish of the Schizodon genus have important representation in the largest South American basins. Historically they underwent through several taxonomic revisions, due to their high phenotypic plasticity and the ontogenetic characters found among the species of this group. The goal of this work was to evaluate the congruence between the molecular units (MOTUs) and the nominal species currently valid, using the DNA barcoding and coalescent methods. DNA extraction, amplification and analysis of the mitochondrial COI region from 68 samples were performed; additionally, 19 sequences available on the BOLD system were added to the analyses. The CodonCode Aligner program was used to edit the sequences and alignment. The genetic distances were calculated in the MEGA 7 software, using the K2P model (Kimura 2-Parameters). For the distance-based species delimitation, the DNA barcoding method was used with three different values of thresholds (2%, 1.4% and 1%). Although evidencing different numbers of MOTUs, the results were congruent in suggesting a possible synonymy of S. jacuiensis and S. platae. With the thresholds 1.4% and 1%, S. vittatus was subdivided into two MOTUs, evidencing the existence of a potential cryptic species. These results were corroborated in the GMYC (Generalized Mixed Yule-coalescent) species delimitation analysis. Thus, the findings of this work show that there are disagreements between the molecular units and the currently valid taxonomy for the genus. This indicates that an extensive taxonomic revision, using morphological and molecular tools, which include different genes, is still needed for a better decision on the taxonomic status within the Schizodon genus.

The discussion scenario for Special Education (SE) and Inclusive Education (IE) is a reality today and means that it does not occur only in the theoretical field. The difficulties and challenges are related to different aspects shown by many studies that verify that, unfortunately, exclusionary situations in school everyday. The same scenario is noted when we focus in school physical education (SPE). Therefore, the topic of this research is related to SPE and SE. The general objective is: to analyze the exclusion factors of people with disabilities (PWD) in SPE. The specific objectives are: 1) to describe and study the life trajectory of PWD focusing on lived experiences during physical education (PE) classes at school; 2) to study the relation between SPE of PWD and their involvement with sports; and 3) to analyze the PWD conception of PE. The theoretical framework is based on Dermeval Saviani's Historical-Critical Pedagogy (HCP), as well as EE studies such as Jannuzzi (2004a, 2004b) and PE studies such as Chicon (2015), Darido (2003) and Castellani Filho (2003), which will help to discuss its contextualization, conceptions, purposes and contents. The chosen referential is the thematic oral history, focusing on five axes to conduct the interviews. The selected collaborators are four adult educated athletes, with ages varying from 17 to 63 years, who play in adapted teams in the city of Sorocaba and are already attending school as a disability person. The analysis of the interviews identified and classified the contents that most appeared at the narratives. After that, constructed data was interpreted according to the theoretical framework of the research, pursuing to answer the proposed questions. Finally, it was possible to realize a concrete analysis of the real-life movement of the PWD, considering their past in the SPE, identifying as exclusion factors: 1) the teachers' approach; 2) the dissemination of content without a dialectical interface with the social function of SPE; 3) the fragility in legitimation of SPE’s purposes; 4) the discrimination and society’s difficulty in understanding people instead of judging someone by their disabilities; 5) the unpreparedness in some professionals training. It should be emphasized that it was not intended to assign value judgments to historical moments of the SPE, but to perform a critical analysis to understand such factors, assuming a political position of discussing the reality of PWD in these classes through their own trajectories: “Nothing about us, without us!”. It is expected to contribute with a quality education and encourage further studies focused on educational practices, which prepare individuals to intervene and overcome barriers that are put by society and thus ensure everyone’s right to acquire knowledge and contents about body culture, aiming a truly inclusive SPE.

Precise estimates of energy production and consumption are essential to promote the integration of renewable energy sources to the electrical grid, guiding power supply balance through cycles and fluctuations inherent to these resources. In this scenario, many experiments have developed solar radiation forecasting methods, but not so many of those apply Recurrent Neural Networks and their potential of modeling time series. This dissertation reviews some of the studies and outlines an experiment comparing Recurrent Neural Networks, XGBoost and persistence of Clear Sky and Clearness indexes in solar irradiance forecasts. Model precision is verified in minute observations from Denver and Las Vegas, re-sampled in resolutions of 5 minutes, 30 minutes, 1 hour and daily mean. XGBoost gives the best results in all forecast horizons, with nRMSE between 12.9% at 5 minute resolutions, and 21.2% at daily mean. Persistence models for Clear Sky and Clearness indexes show comparable precision, with nRMSE from 14.2% to 22.5% in forecasts up to 1 hour ahead. RNNs outperform persistence in forecasts of daily mean irradiance, reaching nRMSE 21.3%.

This dissertation addresses the problem of designing a humanitarian supply network. With this purpose, a mixed integer linear programming model is proposed, which aims at maximizing the covering of demand in the affected municipalities. The proposed model considers facilities having two purposes (which operate as deposits and aid centers), and is used to decide on capacity planning upon the basis of the Social Vulnerability Index (SoVI) that prioritizes the care of more vulnerable areas. For the sake of testing the model, a real case based on the Brazilian disaster response planning was considered. Thus, data was gathered from the Integrated System Disaster Information (S2iD); in particular, the 11 types of natural disasters with the highest prevalence during the period 2007-2016 were used for the study. The goal was to estimate the demand for relief aid required to cover population needs in the affected municipalities. Computational experiments were implemented and executed to evaluate the mathematical model. The results suggest that the model proposed may be used as a decision support tool that allows for evaluating: (i) the configuration of the humanitarian supply network, regarding to the deposits and aid centers, as well as their characteristics in terms of capacity and long-term operation, (ii) the dynamics of transportation of relief aid throughout the country to meet the requirements (iii) sensitivity analysis of the budget to the care of victims and the role of SoVI in the level of emergency service; and (iv) the advantages and disadvantages of combining pre-positioning and acquisition of relief aid to take the care of victims.

The Internet of Things (IoT) is considered one of the emerging technologies in the area of information technology. The use of this technology provides an improvement to the population by providing better transportation systems, health and electrical infrastructure, among others. However, collecting information in these spaces can cause serious damage to the user’s privacy, which is one of the challenges to be overcome by IoT. In some scenarios, the user may provide personal information without being aware of the risks to their privacy. Cryptographic primitives with a high computational cost are used to maintain the privacy of users in IoT environments, but they are not applicable to all devices due to their heterogeneity. In this context, this work proposes a mechanism of preservation of privacy that aims to mediate the information exchanges that occur in IoT environments. This proposal was based on a research done with users that aimed to validate the characteristics and functionalities of a mechanism with these objectives. The privacy preservation mechanism was developed as an application to provide ease in user interaction with IoT environments. The validation of the application was performed by an experiment with the users, where they were submitted to several IoT scenarios. The results show that, with the use of the mechanism, users feel more comfortable with the availability of their data in these environments. The learning process of application privacy preferences obtained a success rate of 88.62% in the predicted scenarios and is considered satisfactory for decision making procedures for the provision of personal information.

This work aimed investigate the perspectives attributed to the teachers about their performance at one daily care in the city of Sorocaba towards the judicialization context of vacancies in the Childish Education. It also aimed to understand the challenges and possibilities of the staff performance since demands provoked by the implications of the judicialization in the daily care center. The study approaches the concept of perspective from the cultural-historic theory of Vigotski (2008). Three teachers of one daily care center have participated in this study, thus having as methodological strategies the participant's observation, records in field diaries and interviews semi-structured. The results show that : a) the judicialization was noticed by the participants as one fact that denotes the incapability of the region to fulfill the legal determinations towards the attendance of the children at 0 to 3 years of age; b) the teachers recognized the law of small children to education, but reinforced (that) the judicialization has produced a few alterations in the school routine and in the educative work, causing situations like the superpopulation of the classrooms, what imposes the necessity of adjustments in the educational attendance offered. c) the reports of the participants signalized that the team has been trying to create alternatives to lead with the existing difficulties, but the living reality is difficult, mainly due to the following aspects : a few human resources, a precariousness work and an increasing outsourcing of the services of the district, through the hiring number of professionals in the daily care centers. They argue that the right of the child to the educational attendance in the daily care center must be guaranteed, as what is recommended in the Law as well as in the official orientations of the Child Education. However there are several challenges to be faced against actual nonliberal polices which include the progressive decreasing of public investments and the outsourcing of services in the field of Education. We can conclude that educators, managers, social movements and communities need to articulate, thus charging from the responsible administrative organs the respect from the children's rights, as well as fight for the improvements in the Child Education attendance in district.

The objective of this work was to evaluate the diversity of Ichneumonidae (Hymenoptera, Ichneumonoidea), with emphasis on the subfamily Pimplinae at three different altitudes in the Serra do Japi Biological Reserve, Jundiaí, SP, Brazil. The samples were collected using malaise traps installed at altitudes of 896 m (A1), 1,082 m (A2) and 1,190 m (A3) in a period of one year (October 2015 to October 2016). A total of 4,196 specimens of Ichneumonidae were collected from 18 subfamilies. Cryptinae, Pimplinae, Campopleginae, Ichneumoninae and Orthocentrinae were the most abundant subfamilies. The highest altitude site (3) showed greater abundance with 1,625 individuals (38.73%); in the other two collection points (A1 and A2) presented greater wealth (18 subfamilies). The subfamilies with cenobiont habits (11) were the most abundant (56.12%). The highest diversity and equitability indexes were found at the lowest altitude; the highest quantitative similarity occurred between the lowest and highest altitudes; the highest qualitative similarity was found between the lowest and intermediate altitude sites. The 745 specimens of Pimplinae were identified in 18 genera and 91 morphospecies. Males accounted for 50.6% and females accounted for 49.4%. The most frequent specimens were of the genus Pimpla (54.23%) and Neotheronia (16.37%). P. caerulea Brullé, 1846 was the most frequent species (43.62%). For Pimplinae, idiobionts were more frequent (530) attributed to 3 genera. The abundance was higher in the lower altitude site, with 293 specimens collected; the highest richness in the highest altitude site, with 56 morphospecies. Higher values of diversity and equitability index for Pimplinae were found at intermediate altitude, and the lowest and highest altitude sites were similar quantitatively; and the intermediate and high altitudes qualitatively. At different times of the year, the highest abundance values of Ichneumonidae and Pimplinae were recorded in hot and rainy periods. A new species was found for the genus Acrothapus and two for the genus Polysphincta. The Serra do Japi is home to important fauna of Ichneumonidae and Pimplinae, which makes it necessary to increase knowledge in this region.

A subject of constant discussions, scientific communication, since the seventeenth century, has been undergoing several changes. One of the most dramatic of those was from the middle of the last century with the emergence of the periodicals crisis, triggered by the explosion of the costs of subscriptions to international periodicals. In contrast, with the advent of the internet, STS studies, and also, the open access movement to scientific publications, new proposals begin to emerge, implying an open science and results available to all. On the other hand, research funding agencies have increasingly demanded that the researchers they fund publish in journals with a high impact factor, many of them, including paid access, generating future expenditures for the acquisition of journals by public libraries. As an example, only in 2017, the federal government in Brazil spent nearly 107 million dollars to maintain the CAPES Periodical Portal. Given the above, the aim of this research is to compare the methods of publication and knowledge dissemination by researchers and professors on the Postgraduate Programs in Exact Sciences (CCET) and Human Sciences (CECH) at UFSCar, and to verify what percentage of this output is in open access. Because it has a quantitative-qualitative research approach, this dissertation is composed of bibliographical research that brings together topics such as the scientific community, as well as communication among peers, their modes of production and scientific indicators. Finally, we discuss some topics relevant to postgraduate studies and the impact of their evaluation system. In the document research we use data from UFSCar, CV Lattes, Qualis CAPES and Sucupira Platform, adopting as a cut-off period the years 2013 to 2016 (last CAPES four-year evaluation). For the mapping of the bibliographic production of the researchers investigated here, we used the ScriptLattes software. With the data tabulated, we consulted which journals were registered in DOAJ and SciELO. For those which were not registered, we consulted the SHERPA / RoMEO database to verify the self-archiving policies of the journal titles identified. Finally, we researched articles from these journals on Google Scholar to see if they had copies available in open access repositories. The research results identified 19 programs, 434 teachers and the publication of 308 complete books, 1162 book chapters and 4638 scientific articles. From these, we find that the PGPs in the Exact Sciences have mostly male researchers, with predominant publication of articles in subscription scientific journals. On the other hand, in PGPs in the Humanities, there are more female teachers, with a higher percentage of publications in books (complete or chapters). Regarding the scientific articles, we could observe the predominance of publications in open access journals for programs in the Humanities. When accessing subscription journal articles on Google Scholar, we find the vast majority of them have open copies available. We conclude that our objectives have been met and we stress the importance of further studies on this theme.

This research aims to ethnographically study the circuits of exchange that are established between incarnated and disincarnated agents in the activities of a spiritist center in the city of São Carlos (state of São Paulo). Through the description of what is done on a daily basis within a spiritist institution, the analysis seeks to apprehend the circuits of gifts and hierarchical processes involved in lectures, psychic sessions, prayers, passes, study groups and charitable practices, focusing on the effects of relationships thus established and its centrality in the construction of the spiritist notion of person. Spiritist practitioners establish their religious experiences around the movement of energies, words, spirits, knowledge, healing, feelings, messages, objects, etc. Such sets of spiritual and material goods constantly traverse the planes of existence (physical and spiritual) and evolutionary layers that make up the kardecist view of the cosmos. This image of the universe is organized in terms of hierarchical levels, a principle that also guides relationships between incarnated and disincarnated actors on Earth. The discussion of these aspects, alongside with a reflection on reciprocity and debt, aims to offer an understanding of spiritism as a system – morally and cosmologically – for circulation, enabling a relational and dynamic perspective of the daily religious experiences in the spiritist center.

The construction industry is the main generator of waste in the economy. The CW can account for up to 70% of total urban solid waste produced (SINDUSCON, 2015), resulting in a concern for the waste of materials extracted from nature, with their illegal disposal and consequent increase in demand for landfill areas. The CONAMA Resolutions and NBR 15.114 (ABNT, 2004c) presented the guidelines for the correct destination of the residues and the development of the CW recycling activity as one of the ways to solve this problem. In addition, Marques Neto (2003) and Córdoba (2010) demonstrated that almost all CW, represented by Class A waste, can be recycled with the production of recycled aggregates. The development of the recycling of CW class A in Brazilian territory was verified in the research of Miranda, Angulo and Carelli (2009) with the identification of 24 units of plants in the State of São Paulo, with only 3 located in small municipalities, with population below 100.000. At the same time, even with lesser generation of waste, they together contribute a significant percentage of CW generation, representing 87.90% of the total municipalities of the State of São Paulo (IBGE, 2010). In this sense, this research had as objective the accomplishment of technical visits based on the content of the bibliographical revision with the proposal of basic project that resulted in the presentation of technical parameters and elaboration of costs for an economic feasibility analysis on the implantation and operation of recycling plants of CW class A, in three case studies defined as small municipalities, with a population range between 10 and 100 thousand inhabitants. The municipality of Severínia with production of 3.70 t / h of recycled aggregates presented the project as not feasible. The municipalities of Monte Alto and Votuporanga, with a production of 6.50 t / h and 13 t / h, respectively, presented as a viable investment with positive net present value and capital recovery.

The industrialized precast building systems have been used all over the world in housing construction since the 50’s. In Brazil, as there were no specific standard codes for precast panels until 2016, the use of those building systems have been under the certification of technical evaluations called DATec from the SINAT system. Since the approval of the new code of practice NBR16475:2017 - Wall Precast Panels and the review of NBR9062:2017, many performance aspects related to structural safety, fire, water tightness, among others are now covered, however there is not yet a very clear position regarding thermal performance requirements. In this context, as specific contribution, this research intends to present the results of an exploratory study regarding aspects and design conditions related to precast walls’ thermal performance, according to the code of practice ABNT NBR 15575 and the precast code of practice ABNTNBR 16475. In order to potentialize a greater usability of those systems in Brazil, this study was accomplished through the measurement of the wall surface temperature using a thermal camera and the comparison of the achieved numbers, verifying the importance of design factors that influence the façade's temperature variation through the solar energy absorption at heat flow, impacting wall panel's thermal performance.

This work aims to document the production process and characteristics of the new Brazilian prestressing steel CP-210 RB, as well as evaluating its use viability and to indicate design guidelines for the application in the design of precast prestressed concrete beam bridges. In this thesis, numerical examples of the design of isostatic reinforced beam are presented considering the use of conventional passive reinforcement and prestessed concrete using either CP-190 RB and CP-210 RB steels. Design procedures consider both full and limited prestessing specifications. Typical, design details are also considered. Comparative studies of materials and execution procedures are considered assessing the bridge deck, designed with several girder beams, for execution of the prestressed or reinforced precast beams. The number of girders and the deck width were determined according to the DER-SP specification for road bridges and overpasses. The beam height varies according to the span length. Designs assessed both the Service Limit State and the Ultimate Limit State considering each construction system. From the analysis results, trend lines were determined indicating the class 450 isostatic precast beams for road bridges production cost, with deck width of 14 m and nominal length from 20 to 35 m, considering solutions in reinforced concrete and CP-190 RB and CP-210 RB prestressed concrete options. With the trend lines, it was possible to determine that bridge or overpass for deck structure with lengths greater than 22 m are economically viable with the use of precast prestressed girders using the new Brazilian CP-210 RB steel. This work also presents, for each chosen construction system, the equations to determine the production cost of precast girder as a function of the nominal length of the deck structure and according to the production items unit costs: concrete, formwork, CA-50 steel, CP-190 steel, CP-210 steel and anchorages. The results show that the anchorage cost represents about 15% to 20% of the total production cost of the prestressed beam, beings this cost higher than the concrete and formwork costs in the case of full prestressing. The relative cost of the anchorage decreases with increasing the nominal length of the deck structure.

As a solution to the paradigm of achieving maximum efficiency in a shorter analysis time, Ultra High-performance Liquid Chromatography (UHPLC) coupled to mass spectrometry (MS / MS) have been successfully explored. The biggest problem still liesin sample preparation which causes waste of time and generates residue, demanding usually high use of organic solvents. Methods by direct injection of samples furnishes more efficient and greener approaches and have been efficiently used for LC-MS/MS analysis. The present work describes the challenges involved in the quantification of three benzophenones in breast milk by direct injection of the sample using albumin serum bovine restricted access phases (RAM-BSA). This work describes the results obtained for the determination in breast milk of 2,4-dihydroxybenzophenone (BP-1), 2-hydroxy-4-methoxybenzophenone (BP-3) and 2-hydroxy-4-methoxybenzophenone sulfonic acid (BP-4). . The results of obtained showed protein exclusion levels greater than 82% for three different aliquots (n = 3). The studies of matrix effect, process efficiency and recovery were not satisfactory due to strong interaction of analytes with the RAM-BSA phases and also to memory effect. Sample preparation by precipitation of protein was used as a proof of concept but the memory effect remained even when we used different analytical columns, different elution modes, and bovine milk as a matrix, indicating contamination of the chromatographic system and making it impossible for the validation of the method. The screening of breast milks samples by LC-HRMS obtained from 26 different mothers allowed the identification of BP-1, BP-3 and BP-4 in 88% of the analyzed samples.

This study aimed to: (a) explore the possible risk and protection factors of families of children with disabilities, indicative of school difficulties and typical development, and (b) examine the relationships between parental variables. The participation of 15 Childhood Education teachers aimed to divide the children according to an assessment conducted by the Capacities and Difficulties Questionnaire (CDQ) and the academic part of the Social Skills Rating System (SSRS). In fact, 87 family members (mother, father or guardian) participated in the study, of which 27 had children with disabilities, 30 had children with signs of school difficulties and 30 had children with typical development. Data collection took place in seven municipal pre-schools. In order to meet the objectives, the family members answered, in the form of an interview, to six instruments: Brazil Criteria Questionnaire, Semistructured interview script, Shared and Engagement Routine Checklist between Family-School – parents’ version, Family Environment Resource Inventory (FERI), Family Needs Questionnaire (FNQ) and Social Support Questionnaire (SSQ). The qualitative data were analyzed through the elaboration of subcategories, with the participation of three experts. Quantitative data were analyzed using descriptive methods - measures of central tendency and dispersion. To compare the quantitative data between the three groups, the ANOVA test was used, as well as the chi-square test to perform the qualitative comparison between the groups. The results showed statistically significant differences between the groups. The parents/guardians of the group with children with typical development (GTD) presented better organization and routine supervision, as well as better relations with the school, specifically in relation to the parent-teacher and parent-student dyads. The sociodemographic aspects of the parents/guardians of the group with children with low academic performance and behavioral problem (GAP/BP), together with the paid activity practiced outside the home by most of the participants, have possibly impacted on the difficulty they had to meet at home, follow up on their children’s homework, and engage directly with the school institution. In the case of the group of children with disabilities (GD), even though it was ascertained that the children in this group did not often perform activities at home, established routines for daily life activities and took walks, it was found that they established better relationships with the school than the group of GAP/BP. The discussions and hypotheses raised suggested that the school institutions which GD, GAP/BP and GTD children attended to were related differently to each of their families, assuming that the best interactions were with those with children with typical development. In view of the findings, this research confirmed the initial questions that there were particularities among the families of the three groups, considering that children with typical development had protective aspects from their immediate context to the relations that indirectly affected their academic and behavioral performance. The families whose children showed signs of school difficulties were the group that showed the most unfavorable conditions at all environmental levels ascertained, as well as the identification of a relationship with the most precarious school, either because of their own cultural and socioeconomic conditions or by the posture of the institution. In families where the children had a disability, it was observed the presence of risk and protection mechanisms acting simultaneously, since several conditions were favorable to their development, but the lack of practical and instrumental support may have led to some types of demands.

The objective of this research was to investigate how the teachers of a municipal education center in Sorocaba (SP) perceive the process of evaluation of children in pedagogical practice. The interest in the research theme came up in a context of changing the guidelines of the Municipal Department of Education in relation to the process of evaluation of children in early childhood education, through the document Guidelines for Pedagogical Documentation in Early Childhood Education. This qualitative research (LUDKE and ANDRÉ, 1986) used the methodology of case study, according to Yin (2001), seeking to apprehend the teachers' conceptions about the evaluation process, through interviews and consultation of documents. Understanding evaluation as an inseparable part of pedagogical practice, from a mediating perspective (HOFFMANN, 2014) whose objective is to make decisions to favor student learning (LUCKESI, 2002), without anticipating fundamental education practices (GODOI, 2010; MORO, 2016), we tried to answer the following questions: What conceptions do the teachers present about the evaluation process in early childhood education? How are their evaluation practices and what pedagogical guidelines do they seek to follow in order to achieve them? Which relationships do teachers establish between evaluation and the teaching-learning process of children? With the presentation of the document of the Municipal Education Department there was a proposal for a change of assessment instruments. However, in addition to the evaluation instruments, the document also presented the conception of children as a historical and rights subject (BRASIL, 2009a), being a participant as person and as a citizen in the various social contexts, as well as in the construction of knowledge and culture (OLIVEIRA-FORMOSINHO, 2007). Through the analysis of data it was possible to identify that, although they understand some aspects of the evaluation in a different way, the teachers conceive that their completion occurs daily and using various forms of registration, according to the guidelines of the document and the design of pedagogical documentation. Were verified progress and difficulties faced by teachers in this process of new conceptions and evaluation practices, as well as relationships established with their pedagogical practices. The research poses as a possibility to broaden the discussions on evaluation in early childhood education, in the search for progress in the aspects that are still necessary, so that it approaches more and more of offer of a quality education for young children.

Introduction: The emergence of the Internet and the Web platform raise new possibilities and challenges of management and access to knowledge, stored in digital environments in the form of data. In this context, the tools for description promoted by the Linked Open Data movement are highlighted, through Linked Data principles. The connection and availability of cultural heritage data, present in libraries, archives and museums, offer new possibilities for learning and dissemination of knowledge in Humanities and the vast cultural heritage distributed throughout the globe. Given this scenario, the question is: how do Linked Data principles contribute to the representation and access to cultural heritage collections? Purpose: To analyze the Linked Open Data in cultural heritage institutions, in order to contribute to studies about representation and access to cultural heritage collections. Methodological procedures: This is an exploratory theoretical-applied research, with a qualitative approach, carried out through a bibliographical and documentary survey about the research question. The scientific bibliography and relevant documents were analyzed in order to provide support for the representation and promotion of access to the cultural heritage collections within the scope of the Linked Open Data movement. Results: The results achieved included 1) academic contributions regarding the benefits of using the tools of the Linked Open Data movement, highlighting issues of interoperability (technical and semantic) and data sustainability, 2) the survey of Linked Open Data initiatives in international cultural heritage institutions, 3) the presentation and discussion of data models adopted by the initiatives Europeana and DPLA and the data scheme of the DigitalNZ project and 4) presentation of the solutions developed by the cultural heritage community to use the metadata standards for the Linked Open Data description of cultural heritage collections. These results demonstrated that the cultural heritage community has sought to take advantage of the benefits offered by the Linked Open Data movement, especially with respect to the sustainability of the processes of description and access to the data of cultural heritage collections and, with that, this community seeks to approach the practices and goals proposed by the Digital Humanities discipline.

We used agricultural commodities futures prices to identify speculative bubbles in the Brazilian derivatives markets between 2008 and 2017. We applied the Generalized Supremum Augmented Dickey-Fuller (GSADF) test to analyze if corn, soybeans, coffee and live cattle futures prices moved temporarily away from their fundamental values. This study aimed to fill in a gap in the literature that analyses the existence of speculative bubbles in the Brazilian agricultural futures markets. Our findings support evidence for multiple periods of bubbles in all markets, except for coffee. We found that 40,4% of the bubbles were short-lived, lasting between 3 and 8 days, and that on average, there were more positive (60%) than negative bubbles (40%). Most of the bubbles events occurred in corn, which represented 87% of the total bubbles episodes during the analyzed period. We verified that prices movements during a speculative period were asymmetric, as the initial price variation was usually larger than the last. We expect that our findings can be useful for market participants who trade futures contracts as a way to hedge their cash position, or for speculative reasons. In addition, a better understanding of prices behavior can help market participants to manage their portfolio risk, and help regulators to ensure that trading rules are respected, and markets function efficiently.
