Privacy is the cause of an important concern in the context of mobile applications, once these applications manipulate a countless number of the users’ confidential and personal information through their mobile devices. Previous researches have shown that the manipulation of information through the applications is commonly unknown to the user, or, when known, the reason for this collection is not clear enough. Several automated tools have been proposed to analyze the performance of mobile applications regarding their privacy. However, these tools don’t take into consideration the users’ perception about what they believe to be collected and the purpose of this collection. Concerning this, the current work presents an approach for privacy applied in the mobile context, in which people’s expectation of the aspects of collection and the use of information by smartphone applications are considered. This study shows the results of a research performed with 163 smartphone users which was used as a basic resource to understand how people’s expectations may impact their subjective feelings (levels of comfort). WePrivacy service is also presented, mainly composed of a mobile application, a concept which implements the idea of privacy and responds the question of research discussed in this work, that is, how to consider people’s expectation in the evaluation and support to the decision making on privacy in the use of mobile applications. The results found suggest that the users don’t know how to point which of their personal information are collected and to which purpose the collection serves. The results also show that when the purposes of the collection are known, the users tend to feel more comfortable.

Since its early development, cinema has been used in education due to the capacity of influencing how people think and behave. Most of the films and especially those categorized as animation, however, have adaptations and poetic licenses that allow an escape from reality, even if partially. Therefore, starting from film exhibition, followed by questions and a qualitative analysis of the answers, perceptions about “Finding Nemo” were got and, aimed at better understanding the influence of this cinematographic resource on the construction and consolidation of scientific knowledge. In total there were 32 participants, with 12 years old age range. Results show that even with some evident discernment between fiction and reality, much information in the film are still assimilated as true. So, to avoid a misappropriation of the scientific knowledge, and consequently its dissemination, it is fundamental that the way how films are used in education is rethought and re-adapted.

La investigación tiene como objetivo analizar el proceso de difusión de la fe, de la religi-osidad y de las simbologías chamánicas en el contexto amazónico para los centros urbanos brasileños. Se identifica su expansión a través de movimientos migratorios al norte del país, en el contacto cultural entre indígenas y no indígenas, y en la formación de nuevas religiosidades a partir del té ayahuasca. En la segunda parte del trabajo se buscó compren-der el chamanismo urbano a través de un estudio, del caso de Cielo Beija Flor Dourado, localizado en Sorocaba-SP. Em el que el debilitamiento y las carencias ocasionadas por la modernización frente a diversas dimensiones de la vida cotidiana como la religión, la pér-dida de identidad, referencias filosóficas y políticas, relaciones comunitarias y distancia-miento de la naturaleza, son los principales motivos que llevan a la producción y a la cir-culación de los ideales religiosos y filosóficos de dicha cultura al hombre de la ciudad, resultando como consecuencia la producción de nuevas territorialidades de la religiosidad moderna, en la formación de una nueva conciencia y en la apropiación mercadológica de estos elementos por el mercado capitalista.

Contemporary Brazilian cinema, particularly the one committed to revisiting the urban periphery, ends up refreshing some aspects of relation between the film and the social context, aesthetics and politics, theme and form, between fiction and reality. And in doing so, it maintains an already long-standing background dialogue which has privileged sociology and anthropology as interlocutors. That said, three orders of problems guide the theoretical-analytical fabulation that I develop. The first is the problem of fiction as a space of conformation for certain phenomenological ambiguities and the articulations that follows; how certain exteriorities are internalized in the film in a blurring between the fictional and the nonfictional, the discursive and the empirical. Next, I investigate how the social sciences tradition and practice (in dialogue with documentary aesthetics) are mobilized as epistemological models and referent of privileged access to the real. The third is the problem of the real itself as a raw material on which the discourses are based, of the real as a value, and communicating with an argumentative vocation of the film, of diegesis as a corpus and narrative as a thesis. I start, therefore, from the form, from the level of the meaning of the cinematographic device properly, so as to reconstitute the bonds, affinities and assumptions of engagement of the film with the real 'in' and 'out'. In the first part of the thesis I present a theoretical-methodological and historical-conceptual approach to these impasses. Thereafter I propose five essays about five films that are quite different from each other, but which share the gravitation around the themes of urban periphery, poverty and violence in Brazil: Cidade de Deus (2002), Linha de passe (2008), Tropa de Elite e Tropa de Elite 2: O inimigo agora é outro (2007 e 2010), O som ao redor (2013) e Branco sai, preto fica (2014).

Excessive salt intake has been associated with the development or worsening of chronic diseases such as hypertension. Spontaneously hypertensive rats (SHR) have a typical increased sodium preference. The lateral parabrachial nucleus (LPBN) acts as an important inhibitory mechanism for sodium intake control, besides its involvement in cardiovascular control in normotensive rats. However, the involvement of LPBN in cardiovascular control and sodium appetite is still unknown in SHR. The aim for the present study was to evaluate cardiovascular responses and 0.3 M NaCl intake after α2-adrenergic receptors activation in LPBN in this model of essential hypertension. In SHR, bilateral injections of moxonidine (α2-adrenergic/imidazolinereceptors agonist) in LPBN increased 0.3 M NaCl intake induced by water deprivation – partial rehydration protocol (WD-PR), without changes in water intake. However, LPBN moxonidine injections did not significantly change 0.3 M NaCl or water intake induced by WD-RP in normotensive Holtzman rats. In normohydrated SHR moxonidine injections into the LPBN did not change 0.3 M NaCl and water intake, mean arterial pressure (MAP), heart rate (HR) and baroreflex responses. The WD-PR protocol did not change baseline values of MAP and HR in SHR, neither after LPBN moxonidine injections. It was also observed that LPBN moxonidine injections in SHR resulted in a positive sodium balance, characterized by increased 0.3 M NaCl intake during the sodium appetite test followed by increased renal sodium excretion and urinary volume at the end of the experiment. Therefore, present results show thatα2-adrenergic/imidazolinereceptors activation in the LPBN increases WD-PR-induced sodium appetite in SHR. This effectis not related to changes in arterial pressure. Therefore, we can conclude that LPBN inhibitory mechanisms contribute to limit sodium intake also in Spontaneously Hypertensive Rats.

Winter corn (second crop corn) has become the main autumn-winter crop in Brazil. In the 2016/2017 crop, the average productivity was 5,303 kg ha-1, surpassing that of the summer corn (first crop corn). With the expectations of increased productivity and expansion of the cultivated area, there will be a need to supplement sowing fertilization with N in topdressing fertilization, a practice often suppressed due to water deficit in the period of extemporaneous cultivation of winter corn. The use of green manure species between the crop row in consortium with winter corn has been recommended to maintain soil moisture. In addition, considering that the N of green manure can become available to the main crop through in vivo mechanisms in intercropping, it is possible to decrease the amount of N offered in topdressing fertilization. The aims of this study were: (i) to evaluate biometric, nutritional, and production parameters of the winter corn (hybrid 30A37 PW), cultivated in consortium with green manure species and with doses of nitrogen in topdressing; (ii) the degree of nitrogen fertilization suppression using green manure. The experiment was installed in a dystrophic Oxisol, with a randomized block design and a 4x3 factorial scheme, with five replicates. The treatments consisted of four conditions for establishing green manure (without green manure; Crotalaria spectabilis; Cajanus cajan; Crotalaria spectabilis + Cajanus cajan;) and three levels of nitrogen topdressing fertilization (0, 15, and 30 kg ha-1 of N ), 30 days after the emergency. Dry mass, stem diameter, plant height, number of leaves above the ear, weight of 1000 grains, number of rows per ear, number of grains per row, grain mass per ear, the mass of the ear without straw, the length and diameter of the ear, the height of insertion of the first ear, productivity, and leaf contents of N, P, K, Ca, Mg and S were evaluated. The treatments did not produce significant differences in biometric and productivity parameters, which were lower than those found in the scientific literature. Regardless of the treatment, leaf N levels were above the range considered adequate for winter corn. Except for the treatment in which Crotalaria spectabilis was grown between the crop row and the addition of 30 kg ha-1 of N in topdressing fertilization, all experimental conditions resulted in insufficient P foliar levels. Experimental plots with no intercropping with green manure resulted in plants with adequate K leaf levels. No insufficient leaf levels of Ca, Mg and S were observed. It was not possible to estimate the degree of nitrogen fertilization suppression for winter corn intercropped with green manure species. The average productivity, which varied from 2.2 to 2.4 t ha-1, was considered very low when compared to the average Brazilian productivity and was attributed to the inadequacy of the 30A37 PW hybrid to climatic zoning, to the deficiencies of P and K and probable Zn insufficiency.

The Biotic Integrity Index has been an effective biomonitoring tool utilizing freshwater fish assemblages. In tropical and subtropical countries, however, its use over time has been developing, although adaptation in these regions has begun more recently. This study aimed at the creation of a Biotic Integrity Index for the municipality of Sorocaba - SP, where it aims to assist in the monitoring of aquatic environments in the urban zone using as bioindicators the fish of streams. A total of 2492 individuals were collected in a total of 27 stretches, 23 in the urban area of the city of Sorocaba and 4 in the Ipanema National Forest in Iperó. An environmental protocol was also applied in all the excerpts to verify the physical characteristics of the streams and later used to promote correlations between the biotic variables. Seven variables were selected to compose the Biotic Integrity Index, being separated into three groups with a response capacity, such as species diversity, habitat and trophic function. Two streams were classified as excellent (7.5%), five as good (18.5%), five regular (18.5%), eight poor (29.5%), two very poor (7.5%), and five without fish (18.5%). The biotic integrity index proposed for this work presented a satisfactory correlation between the environmental conditions and the fish communities due to the presence of a environmental gradient capable of generalizing impacts in the urban region of the city of Sorocaba. This work has demonstrated that studies like this one besides being able to promote applicability and development of methods for environmental biological evaluations, also has as consequence a better knowledge of the freshwater fishes.

Heterocyclic compounds containing the 1,2,3-triazole nucleus have received special attention in the field of synthetic chemistry have seen that have a wide field of application in biological and material areas. In this work, a new methodology was developed through a more sustainable approach for the synthesis of 1,2,3-triazoles, employing microwave irradiation as a heating source for the 1,3-dipolar cycloaddition reaction. As dipolarophile, β-dicarbonyl compounds, commercially available and others prepared by means of transesterification reactions between methyl acetoacetate and different alcohols were used. As the dipole species, different organic azides were prepared via a diazonium salt formation reaction. The triazoles were synthesized using nanoparticles of copper oxide II as catalyst under microwave irradiation. This new protocol allowed the preparation of a broad scope of highly functionalized 1,4,5-trisubstituted 1,2,3-triazoles in the short reaction time, in good to excellent yields. At the end of the synthesis, a study was performed on the recovery of the nanocatalyst, being possible its use for up to 3 reactional cycles with good yields of triazoles. Still in the context of more sustainable methodologies, the continuous flow reactors have been successfully applied in the development of new synthetic methodologies, since the efficient transfer of heat and better mixing of the reactants, has implied a smaller amount of byproducts and high conversion rates, among other advantages. In this part of the work, a new methodology for the synthesis of 1,2,3-triazoles 1,4,5-trisubstituted was initiated, via a reaction of 1,3-dipolar cycloaddition between carbonyl substrates, and arylazides, with reactions catalyzed by molecular sieves under continuous flow regime catalysed by molecular sieves, obtaining high conversion rates in the triazoles.

Given the high workforce participation rates among men and women who have preschool-aged children, it is important to examine evidence about factors that may facilitate the conciliation of paid and family work. In addition to the issue of how to divide one’s time between these two spheres, which may be affected by the parents’ hours of work, the quality of the interactions that are occur in the family and workplace environments is also likely to be important, which may depend on the parents’ social skills. To investigate this issue, a research program was conducted, involving four studies. In Study 1, a literature review was conducted to examine theoretical perspectives used to discuss the interface between paid and family work. It was found that: (a) current theories include negative and positive aspects of the work-family interface; (b) a reduction in work-family conflicts is associated with benefits for the wellbeing of people in these two spheres; (c) workers who reported fewer conflicts had higher levels of work commitment and work satisfaction; (d) there are two instruments for evaluating the relationship between work and family, validated for use in Brazil; (e) various individual, family and organizational strategies contribute to improving the integration of these two roles. In Study 2, the objective was to analyze the effects of paid work hours on people’s wellbeing, in the Brazilian context. Based on the literature reviewed, women with low education, very low incomes and young children tended to have greater health problems because of their double and triple workloads. In addition, workers who had greater problems with their physical and mental health also had lengthy hours of work. In Study 3, the goal was to analyze if there are differences related to gender in the use of social skills, among adults. Evidence was found for the importance of cultural influences on the social skills of men and women. Thus, the objective of Study 4 was to examine the joint influence of work hours, social skills and gender on work-family balance and satisfaction with different facets of life. Interviews were conducted with 142 participants (54 men and 88 women), all of who were in a common law or marital relationship in which both partners were engaged in paid employment, and all were parents of at least one child of up to six years of age. The participants completed the Del Prette Social Skills Inventory, an instrument to evaluate perceptions of work-family spillover (facilitation and conflicts), and scales to evaluate their satisfaction with their job, organization of their home, relationship with their child, marital relationship, and life in general. Some of the key findings were that there was little direct influence of work hours on the work-family balance and satisfaction of the study participants. With respect to social skills, for the men, more so than for the women, their ability to express positive feelings contributed to a reduction in the frequency of work-family conflicts. With respect to the participants’ satisfaction with different aspects of their lives, once again, the satisfaction of the men was more strongly related to their social skills than in the case of the women. Among the women, the influence of social skills was more evident among those who were working part-time. Thus, one can conclude that work hours, social skills and gender are important factors that, jointly, can affect the work-family balance and satisfaction of workers with pre-school aged children. In future studies, it will be important to use larger samples, a longitudinal study design, and more specific instruments for evaluating social skills in each of the areas investigated.

Acai is a widely consumed fruit in the North Region of Brazil and has gained consumers in other regions of the country and abroad. With the increasing acai pulp demand, quality control measures become necessary to improve its trading; however, there are some problems, such as the fast degradation of the pulp, microbiological contamination and no knowledge on the behavior of the organic compounds present in the pulp of fruits of different origins, growing, seasonality, transport and processing. This study describes the influence of seasonality, growing conditions and genotypic variations on the acai pulp from Belém - PA by 1H NMR combined with chemometric methods, and structural characterization of the chemical constituents by LC-DAD-SPE/NMR. This work was performed in 4 stages: I) Identification of the greatest number of organic compounds by 1D and 2D NMR, without the need for isolation; II) Attainment of the chemical profile by 1H NMR combined with the chemometric treatment of the pulp of the fruits of 31 genotypes cultivated under agronomic control (Embrapa Amazônia Oriental) and also of commercial samples (Belém-PA); III) Verification of the correlation between the 1H NMR chemical profile and the physical-chemical data measured in the same samples; and IV) Identification of the organic compounds present in the commercial acai pulp extracts obtained with an ASETM (accelerated solvent extractor), being the major compounds obtained by 1D and 2D NMR, and the minor ones by LC-DAD-SPE/NMR with time-slice as trapping mode. Tendencies in the distribution of the acai pulp samples were observed according to the type of growing (agronomic control x without control), seasonality (harvest season x inter-harvest season), genetic improvement, and the storage system used by the retailers from Belém, and the compounds responsible for such tendencies were identified. The great variability in the physical-chemical data of the evaluated pulps was verified and, thus, there was no correlation with the 1H NMR spectral data. The ASE provided the best extracts when compared to extracts obtained with the conventional method. Some aromatic compounds were isolated from the acai pulp methanolic extract by LC-DAD-SPE, and their structures were determined based on the analysis of 1D and 2D NMR, UV and MS experiments. This study showed the potential of the high-resolution NMR technique to obtain chemical information from the lyophilized acai pulp. The traditional analysis methods (physical-chemical ones) were not viable, since they did not provide good comprehension of the variations of the acai pulps. The ASE extractor was a good alternative to perform the clean-up and extraction of the organic compounds present in acai and the time-slice mode proved efficient in the isolation of compounds at low concentration present in the acai pulp methanolic extract.

The search for more sustainable methodologies has led in recent years to a significant increase in the development of more efficient heterogeneous catalysts, easily recoverable and with high stability over several reaction cycles. In this approach, zeolites emerge as a promising alternative for a wide range of reactions in organic synthesis, since they have unique physico-chemical characteristics, such as high acidity, presence of microporosity and also for acting as supports for catalysts prepared by ion exchange, it being possible then, the insertion of several metallic cations in their exchange sites. From this perspective, this work developed a catalyst exchanged with copper in zeolite β with magnetic support of ү-Fe2O3 that allows an easy and efficient separation of the catalyst from the reaction medium. After synthesis, the catalyst was characterized by X-ray diffraction (XRD), transmission electron microscopy (MET), atomic emission spectroscopy (ICP-OES), X-ray flowering (FRX), excited photoelectron spectroscopy (XPS). The magnetically recoverable copper catalyst (ү-Fe2O3-β-Cu(I)) was used in the synthesis of 1,2,3-1,4-disubstituted triazoles in a multicomponent approach with formation of azide in situ using water as a solvent. The optimization of the reaction conditions was performed using the benzyl bromide, sodium azide and phenylacetylene reagents as model substrates. In the optimization stage, different reaction parameters were evaluated, such as temperature, time, solvent and amount of catalyst. With the result of the optimization in hand, a study was carried out on the scope of the reaction, where the products were obtained with good to excellent yields. At the end of the synthesis, a study was carried out on the recovery of the catalyst, being possible its reuse for up to 5 reaction cycles leading to triazoles in good yields.

Aluminum extrusion is a thermomechanical process widely used throughout the world, and the performance of this process is strongly dependent on the quality of the tool steel used in the manufacture of the dies. In this context, the present study aimed to evaluate and compare the mechanical and microstructural properties of AISI H13 and VEX hot work tool steels, the effect of re-nitriding on die recovery and tooling performance in field tests. The samples were nitrided with gas and plasma for comparison purposes. The effect of re-nitriding was simulated by performing eleven consecutive nitriding cycles on the samples. The samples were characterized by chemical analysis, metallography, X-ray diffraction, SEM-EDS, hardness tests, impact tests and machinability tests. The tubular dies made of both materials were used in the extrusion of AA6060 aluminum alloy profiles for performance evaluation. The results showed that the increase in the number of nitriding cycles influences the surface nitrogen concentration, the white layer and the diffusion zone thickness, the surface oxides growth, the nitrided layer hardness and the substrate hardness. The residual stress profiles of the nitride layer and the effect of the alloying elements on the temperability of both materials were also compared. The experimental simulation of the effect of the working temperature on the dies proved the superior performance of VEX when compared to H13. The higher wear resistance of VEX was attributed to higher resistance to the tempering of the nitride layer and the substrate and depth of the nitride layer after the same number of nitriding cycles.

Our objective in this research was to analyze the assessment procedures and instruments of the teaching work, as well as the education quality and assessment conception, by the teachers and the institution. We began with the hypothesis that the assessment would have a quantitative characteristic, whose tendency would be measuring the productivity. As a start, we analyzed institutional documents, such as: institutional assessment reports; statistical yearbooks; assessment instruments; documents from the Assessment Forum; resolutions; ordinances; letters; instructions; related legislation; and also journals and publications of the servers and teachers union. We could obtain data about the university, its distinct expansion cycles, teaching work and assessment processes to which it is submitted. In a second part of the research, we conducted eight semi-structured interviews with teachers with different profiles. The reports expressed important nuances about the work conditions and views about the assessment processes and the education quality. There were both contradiction as convergences among the conceptions of assessment and quality of the institution and those supported by the teachers. The teacher views about the effects of the assessment system vary according to the profiles and different positioning toward the current policies and the practices in the university. We noticed some specificities in the teaching work assessment at UNESP and its instruments. These, built in the historical context of the State Reform and subordinated to the managerialist ideology and to the productivity and efficiency indexes, assume prominence. The instrumental rationality connects to the effort of the consolidation of the research and the post-graduation. What implied in the hyper-bureaucratization, expressed in hyper-normativity in the performance punctuation. We verified an infinity of resolutions, commission and management structures of teaching work control and its production. The hyper-normativity implies work intensification and results in obstacles to the education quality. The quantophrenia and the instrumental rationality start become part of the university routine, awakening the accession of many who believe in the possibility of measuring the quality of the education, and tend to naturalize the academic productivism and the quantitative assessment of the performance. Yet, also awakened criticism and questionings. Although there was a trend of naturalization of the academic productivism and the assessment processes, most of the teachers pointed to impasses, if not obstacles, to the realization of the education quality.

Nowadays, with industrial development, the concentrations of toxic materials produced and dumped by factory and domestic waste are increasing. The heavy metals are part of these contaminants which currently contaminate soil and groundwater, threatening the health of all living creatures. For this reason, the environmental monitoring of these metals is increasingly relevant. This work evaluated the development of electrochemical sensors in different architectures and materials, aiming at the detection and quantification of cadmium (Cd) and copper (Cu) metals in contaminated water sources. These electrochemical sensors were constructed by the Layer by Layer (LbL) technique. The LbL uses opposite charge solutions to form self-assembled layers of nanometric thickness by spontaneous adsorption on solid substrates. Sodium montmorillonite clay (MMT-Na +) and b-cyclodextrin (b-CD) are materials whose structure provides adsorption capacity of metal ions. Therefore, they were selected to be immobilized in the self-assembled films. Besides these materials, will also be tested the use of gold nanoparticles (AuNPs) to verify the improved sensitivity to the analytes. These AuNPs were synthesized in two shapes: nanospheres (AuNEs) and nanoroads (AuNBs). In this way, films were constructed in the (PAH/MMT)10, AuNEs/MMT)10, (AuNBs/MMT)5 and (PAH/b-CD)5 architectures. The self-assembled films were characterized by spectroscopic and voltammetric analyzes, to verify the growth of their layers and their detection efficiency through the Cd and Cu metals in solution. The electrochemical responses for all tested architectures were successfully obtained. The films built with MMT-Na+ clay presented potential for quantification of metals in wastewater, according to the standards established by the Environment National Council (CONAMA). However, the results obtained at the detection of metallic ions by the b-CD films were more sensitive, allowing the quantification of metals in the maximum permitted concentrations for drinking water according to the guidelines of the World Health Organization (WHO).

Orchid bees (Apidae, Euglossini) are important Neotropical pollinators. Two main features characterize these species: the tongue, which reaches at least half the body length, enabling the search for food resources in general, and the habit on the part of males of collecting aromatic compounds from various plant sources, which is a behavior that is unclearly associated with reproduction. Euglossa cordata is commonly found in cities and has primitive social behavior. Its nests are generally small and often reactivated in relationships between mothers and daughters, sisters or even unrelated females. Although Eg. cordata has been widely studied with regard to ecological and sociogenetic aspects, few studies have investigated how its occupation of the different environments occurs or its patterns of distribution over larger areas, especially with the use of more than one type of molecular marker. The 229 specimens analyzed were from 13 different Brazilian states distributed among the five major geographical regions (central, northeastern, northern, southeastern and southern Brazil). Genetic analysis were performed to verify the suggested sex-biased dispersal pattern, as well as determine population structuring and genetic diversity through the analysis of the mitochondrial 16S gene fragment and 15 microsatellite loci. The 20 characterized haplotypes showed considerable haplotype diversity and low nucleotide diversity. The results of the mitochondrial marker analysis also indicate certain genetic heterogeneity among populations, whereas the microsatellite loci indicate greater homogeneity among populations, which is explained by the relationship between dispersal and occupation of the environments by each of the sexes. The occurrence of gene flow, the presumed high number of individuals, the absence of diploid males and the great allelic diversity found suggest a health population. In addition, this work recovered a discussion about the difficulty of amplification of the mitochondrial genes COI and CytB for this species. The data also point to the existence of distinct population groups associated with the coastal and inland regions of the country, suggesting two dispersal routes, which underscores the need for further studies on the species, involving, for example, phylogeographic analysis.

The Libras (Brazilian Sign Language) / Portuguese translators and interpreters operate between linguistic and cultural borders. They are the subjects who mediate the interaction among deaf people and listeners. In the school context, however, their work is not restricted to this primary function, that is, it crosses this conception and goes through other ways which do not encompass just the linguistic and communicative aspects. The Educational Interpreter is called to also assume the educative function, as defended by Martins (2013), building a closer and more significant relationship with the deaf student than the one with the conducting teacher, since they share the same language. In this sense, it is necessary that teacher and interpreter work effectively in partnership, exchanging knowledge and experiences which aim to favor the deaf student’s learning and also collaborate to make student and teacher closer. This is a descriptive qualitative research which aims to analyze the Educational Interpreter operation at an inclusive nucleus school with bilingual project in the countryside of São Paulo state. For data collection, the observation instruments of everyday school were used, with registers on field notebook and semi-structured interview with the research subject. Data analysis was done from authors affiliated to Deaf Studies in Education and also Mikhail Bakhtin’s enunciative-discursive theory on the work Marxism and Philosophy of Language; both perspectives are articulated in order to reflect upon the Educational Interpreter practice, because they notice the professional’s activity as linguistic mediation and, beyond this function, they assume the professional is inserted in a sphere that calls for other functions, mainly the educational function, due to the genre and operation characteristic of the sphere itself. Thus, the results point at: a) the importance of a partnership between Educational Interpreter and conducting teacher when planning the methodologies to be used in classroom; b) the adoption of interpretative strategies with the use of image resources that help the deaf student in knowledge building and help the interpreter to have a higher quality performance; c) the importance of schools starting to give tests in Libras to deaf students, since it is through this language they acquire their knowledge; d) the context of a bilingual inclusive nucleus school favors the construction of a partnership between interpreter and teacher and also makes teacher and deaf student closer; e) the formation of the interpreter who works in the school must be specific, with two main lines: linguistic line, in order to acquire competences in translation and interpretation, and pedagogic line; f) Education Interpreters must be included in the offer of continuing formation by the educational systems. Given this, it is expected that this work contributes to broaden the discussions concerning this professional and to the promotion of a high quality teaching to deaf students.

Servitization is as an emergent competitive strategy for manufacturing companies. One research gap concerns the need to better understand its impact on firms’ performance. Prior empirical studies have provided inconsistent results regarding servitization-performance relationship. Moreover, the existing literature has concentrated on servitization in large-sized companies. This article aims to examine the factors influencing the servitization strategy in small and medium enterprises (SMEs) and the impact of this strategy on SME´s performance. The study uses data from 176 Brazilian SMEs and applies structural equation modeling technique to test a set of research hypotheses. The outcomes provide support for the hypothesized positive relationship between servitization strategy and performance by showing that servitization contributes to increase the financial and non-financial performance for SMEs regardless their level of servitization or proportion of service income. Moreover, external factors directly influence the servitization strategy in SMEs and indirectly affect SMEs´ performance through servitization strategy. This work also discusses theoretical and managerial implications.

Parental Alienation (PA) refers to the behaviors of a parent or family member (alienator) who initiates a defamatory campaign directed at the other parent (alienated), to hinder or prevent the contact of the family member with the child. PA has a scarce number of scientific studies in Brazil and is considered controversial by the scientific literature in spite of the fact that this country has a Federal Law on the subject. Despite the lack of data in the area,forensic professionals, especially psychologists, are called to act in PA cases, and may not be prepared to do so. Thus, the present dissertation has aimed to investigate the familiarity of Brazilian psychologies with PA and how they would use the concept in simulataed cases to subsequentely plan, and evaluate an online training course on the subject, with the purpose of filling possible gaps in the training of suchprofessionals, helping them improve their practices. The results of the dissertation are presented in four scientific papers: the first one refers to an already published review study of Brazilian publications on PA which analyzed 13 studies, verifying that most of them referred to theoretical constructs with questionable validity. The second article evaluated, through an online survey, the concepts of 137 Brazilian psychologists about PA and how they would apply such concept in simulated cases, concluding, among other aspects, that although participants admitted familiarity with the term, they presented difficulties in a case study vignette that with interface with child sexual abuse, demonstrating the need for further training in the area. Article 3 aimed to develop and provide an online PA training and its effectiveness in performance of 40 psychologists in termos of comparison with a PA questionnaire before and after the training. Among the results, statistical significance was found mainly in relation to an increase of familiarity with PA. The fourth and last paper, conducted a social evaluation of 38 psychologists who took the online course. Results pointed out that participants evaluated the training as positive and enriching for their practices. Half of participants presented personal difficulties which were mostly related to personal time management, as well as using resources from the online plataform. Finally, the dissertation unveils the controversial topics associated with PA and the complexity of assessing alegations at risk of minimizing claims of the severe problem of child sexual abuse. In addition, the present work evaluates a pioneer attempt to conduct online training to Brazilian psychologists on PA, which may be a starting point for new empirical studies on the subject, particularly on continuing education to professionals on parental alienation.

This research examines the film Superoutro (1989), by Edgard Navarro, which recovers the films developed by the director in the 1970s and points out issues that reflect the period of political and cultural transition, soon after the political opening in Brazil. The main objective of research is to analyze the film in order to understand how the transformations occurred in the democratization process in Brazil, after the military dictatorship established in 1964. The study was conducted in two methodological steps: film analysis, which includes the analysis of film's internal structure and external analysis, both supported by literature review, incluinding topics based on the film and in method of film analysis.

Since ancient times the soil has always had a very high importance for the primitive, since the soil was used for food production among other peculiarities. Given this, over time the interest in soil studies were gaining prominence as the study related to soil formation and microorganisms present. With this, it was discovered that many microorganisms present in the soil had beneficial characteristics, and this generated the greater interest to better understand everything that was related to the soil. Taking into account all these points, it is known that in Brazil there is a Brazilian Soil Classification System, which makes it possible to understand what types of soils exist and their characteristics. This is essential in order to understand what type of microorganism is capable of developing, what crop can be planted, and how the soil was formed. However, to obtain an increasingly consistent interpretation of a soil, macro and micronutrient analyzes, pedogenesis, and lately a new analysis has emerged to corroborate all the data, the metagenomics. Therefore, joining all these analyzes is possible to understand all interactions in the soil, including the diversity of microorganisms present. In order to understand all interactions in the soil, samples were collected at the Sugarcane Technology Center (CTC-SP), and these were represented by three different soils, and in these samples physical-chemical analyzes and metagenomic analyzes were performed, which were based on the sequencing by contemplating the V3 and V4 regions of the 16S RNAr gene through the Illumina MiSeq protocol, and later bioinformatics analyzes. From all the data collected and processed through software, these were confronted with the "Silva" bacterial database, and this allowed to determine the bacterial diversity of each type of soil taking into account the levels of taxonomy. Finally, all analyzes were correlated to understand all interactions in each type of soil.
