It is proposed a possible new line of research in which distributions are combined. Combined distributions are an alternative for adjusting continuous data that present different probabilistic behaviors. A combined distribution called Gucumatz is developed, composed of the symmetrical Normal and Cauchy distributions. Some properties of this distribution are studied, maximum likelihood estimation of augmented data is performed (EM Algorithm), regression model and simulation studies are developed. A set of real data is adjusted using the Gucumatz distribution.

Historically the market has become more dynamic and competitive, so customers needs and desires have become increasingly refined. Thus, clearly understanding the requirements and making the product available at the right time to the market become crucial competitive force for the business. As a result, the present study aimed to carry out an analysis seeking to identify an existing relationship between the use of customer interaction in the development phase of a new product, reducing the time of the project execution and, consequentialy, the time-to-market. This work was developed from a quantitative analysis in a consumer goods company from school supplies sector. For the evaluation of the central question, a questionnaire was made for people responsible to lead the new product development area of the company. It was possible to treat the information obtained and establish discussions and conclusions around the main idea. The results of the research demonstrate that the user's participation in the development stages of a new product can impact on the reduction of the time used in the project execution if its planned correctly and applied since the initial stages of product design.

The search for a healthy lifestyle leads to a situation where several people start to take care of their health. From then on, they seek products of higher quality, preferably with health benefits, rich in vitamins, bioactive compounds, bioelements, and valuable nutrients. In this sense, bee pollen, which is rich in functional components, can satisfy these expectations when added to processed products and be better used as an ingredient in the food industry. One of the fastest-growing categories is the bakery category, mainly focused on producing artisanal or rustic bread, with the appeal of "more natural" or" healthier" because it does not contain synthetic additives in its composition. Thus, natural fermentation bread has been gaining market and winning more concerned about a healthier lifestyle. Given the above, we believe that it is important to study consumers' behavior concerning developing new products in the bakery sector. Thus, this study aimed to analyze the acceptance of artisanal hamburger bread added with bee pollen, as well as, how consumers perceive specific natural compounds for health promotion and their attitudes towards accepting this bread.

In this master’s dissertation has investigated the use of deep eutectic solvents (DES) for the development of electrochemical sensors. DES was immobilized on the surface of a glassy carbon electrode (GCE) within carbon black (CB) nanoparticles in chitosan (CTS) films crosslinked with epichlorohydrin (ECH). During the electroanalytical method development for the simultaneous determination of acetaminophen (ACP) and diclofenac (DCF), the experimental conditions were optimized, such as composition and concentration of the DES within the modification, support electrolyte’s pH, time, and applied potential for the analytes pre-concentration, and instrumental parameters for the differential pulse adsorptive anodic stripping voltammetry technique (DPAdASV). The DES applied in this work were characterized by Fourier-transform infrared spectroscopy and conductivity measurements. The proposed modified electrode had its morphological structure characterized by scanning electronic microscopy, which allowed to observe morphological changes after incorporating DES into the CB film. The electrochemical characterization was given by electrochemical impedance spectroscopy to calculate electronic parameters, such as capacitance and charge transfer resistance, and by cyclic voltammetry to calculate the heterogeneous electron transfer constant (k0). The DPAdASV method resulted in linear responses in the range from 5.0 × 10−7 to 3.9 × 10−6 mol L−1 for ACP and from 5.0 × 10−7 to 1.5 × 10−5 mol L−1 for DCF, with limits of detection of 2.7 × 10−8 mol L−1 and 5.2 × 10−8 mol L−1 for ACP and DCF, respectively. The proposed method proved to be precise and selective, observed from studies of repeatability and effect of possible interferents besides addition and recovery studies. The accuracy of the proposed method was evaluated for the simultaneous determination of ACP e DCF in commercial pharmaceutical samples and biological fluids (synthetic urine and bovine serum). The obtained results were compared with those obtained by HPLC/UV-Vis.

Context: Software development companies are constantly seeking practices that improve the execution of their activities and, consequently, their processes. Several initiatives for using gamification have been observed in different areas, providing evidence on different types of activities. However, the implantation of gamification in a real software development environment requires planning and systematization in order to make this alternative effective and efficient. This fact became clear after we performed a systematic mapping of the literature, in which analyzed the initiatives to use gamification, with special attention in the area of Software Engineering. Objective: Establishing a systematic way of applying gamification to activities of the software development process to improve and make more effective activities that need to be improved, with the objective of improving the process as a whole. Method: A systematic mapping was carried out to analyze gamification use initiatives and, concerning Software Engineering activities, some frameworks have identified, but also difficulty in using them. Thus, based on what we found, it has been defined the GSA framework and a strategy of how to apply gamification in software engineering activities. They were defined in an evolutionary way, based on action research. During the cycles of evolution, three experimental studies were carried out, being them a pilot study and two case studies in a real software development company. Such studies allowed us to improve both the framework and the strategy. Results: The results of the studies have shown improvement in carrying out the selected Software Engineering activities with gamification. In the case of the “Timesheet fill” activity, a decrease in more than 75% in the time of filling out the Timesheet was observed. In the case of the “Requirements Reading and Review” activity, we noticed a decrease of at least 68% in the number of defects, when compared with a historical basis of the company, by applying the framework and the strategy to Requirements Reading and Review Activities. Conclusion: The use of a framework and a strategy to deploy gamification in Software Engineering activities contributed to the improvement in the execution of activities that were considered problematic in the context of the company’s software development process, and hence may contribute to the process as a whole.

The aim of this paper is to discuss the paths and objectives in the implementation of Democratic Management in public schools in the Brazilian context, using theoretical frameworks and a survey to analyze the perspective of Pedagogy students regarding the discussion. It is a qualitative research. The methodology used was bibliographic research, through a review of specialized literature and documentary analysis through a questionnaire conducted with twenty-one students in the fifth year of undergraduate studies in Pedagogy at the Federal University of São Carlos, Sorocaba campus. The results showed that a large part of the volunteers only knew the term Democratic Management after entering graduation, in addition, part of the accredited participants had never known a school that exercised Democratic Management, this reveals that the process in legislative form is extremely fundamental but it is still no guarantee that Democratic Management is present in public schools. Thus, when exercised in its integral concept, through the understanding that the school is a historical and cultural form, it is able to articulate the means to the end, mediating the construction of the subject in the historical-critical scope. Circumstantiating the paths taken by Public Educational Policies in Brazil, addressing how democratic management appears in documents and their influences over the years is essential. In this research, we will seek to understand the reasons why Democratic Management has not been built and applied in a broad way in the context of Brazilian public schools.

The dysfunction of the respiratory system is seen in several neurodegenerative diseases such as Alzheimer's, but how the pathophysiology mechanisms of the disease are related to the respiratory system remains poorly documented. Here, we treat animals with intracerebroventricular streptozotocin (STZ, 2 mg / kg). In chapter 1, we measured ventilation (VE), electroencephalography and electromyography during normocapnia, hypercapnia and hypoxia in Wistar rats. In addition, we performed western blot analyzes for phosphorylated tau, total tau and amyloid- (Aβ) peptide at the locus coeruleus (LC), retrotrapezoid nucleus (RTN), medullary raphe, pre-B¨otzinger / B¨otzinger complex and hippocampus, and we evaluated memory acquisition and learning using Barnes' maze. The STZ-DA model increased the ventilatory response in hypercapnia by 26% during wakefulness due to the increase in tidal volume, but no change in VE was observed in room air or ihypoxia conditions. We observed an increase of 93% in the percentage of awake-state time during room air in the STZ model. And, we associate the results to the 73% increase in amyloid beta peptide in the LC region. In order to analyze the electrophysiological properties and sensitivity of LC neurons during hypercapnia (10% CO2, pH = 7) in the STZ-DA model, we performed the patch clamp technique in chapter 2. We observed that most (~ 60%) of the noradrenergic neurons of the LC in adult rats were inhibited after exposure to CO2, as indicated by a significant decrease in the action potential (AP). The STZ-DA model had a 57% higher sensitivity to CO2 compared to controls, which was partly due to the hyperpolarization of the resting membrane potential -52.2 mV. The reduction in AP in both groups was generally accompanied by lower activity of the LC network, depolarized AP threshold, increased AP repolarization and increased current through a voltage-dependent sub-population of K + channels (KV). Then, in chapter 3, we decided to take a treatment with the drug minocycline to reverse the cognitive, respiratory, sleep-awake cycle, and molecular disorders found earlier in chapter 1 in the STZ model. For that, we performed the same techniques as in chapter 1. Additionally, the animals were treated for five days with minocycline at a dose of 30 mg / kg, we analyzed the micrology cells in the LC region by immunohistochemistry for IBA-1 and the pro-inflammatory cytokines by real-time PCR. Minocycline treatment improved learning and memory, possibly due to decreased cell density and inactivation of microglia cells in the LC region, as well as decreased IL-B cytokine. However, the treatment did not reverse the increased sensitivity to CO2 during awake state in room air. Likewise, we did not observe a decrease in the expression of beta-amyloid peptide in the LC region after treatment. Our study demonstrates that the ventilatory response to CO2 is increased in the STZ model due to changes in the noradrenergic neurons of the LC, which have their electrophysiological properties altered possibly by an increase in beta-amyloid. The cognitive and sleep changes observed in the STZ model are due to changes in microglia, since the use of minocycline was able to attenuate

Xanthan gum is a polysaccharide produced by bacteria from the genus Xanthomonas. This biopolymer has many industrial applications such as in food and cosmetics production, oil extraction process, among others. There is no national production of this compound, which leads us to import high volumes of xanthan gum annually. Currently, the development of production processes for this biopolymer has focused on the optimization of growth media and operational parameters, as well as on downstream steps to recover the product from the fermentation broth. However, a key aspect of this process is the development of optimized strains. In this context, a deterministic model in Python developed by Kundlascht (2017) identified the reactions catalyzed by UDP-Glucose pyrophosphorylase (UDPG-PP) and UDP-Glucose dehydrogenase (UDPG-deH) as being the bottleneck of the xanthan gum biosynthesis pathway. The model predicted the system behavior with the enzymes’ super-expression, indicating a significant rise in the gum monomers synthesis. From these results, the present work sought the hypothesis validation performing the cloning and the transformation of the genes galU (UDPG-PP) e Udg (UDPG-deH) in Xanthomonas campestris pv. campestris (XCC) using a broad host range plasmid as the backbone. Three plasmids were then produced containing each individual gene or both genes together, which were respectively named pLACR1_deH, pLACR1_PP and pLACR1_OP. To evaluate gum production by the new transformed strains with the constructed plasmids, cultures were performed in shake flasks with two different inducer concentrations. The results showed up to 21.7% more productivity (Pr) of xanthan gum for the best recombinant strain compared to the parental strain. This result validates the initial hypothesis about the pathway bottlenecks identified by in silico analysis.

This study aims to present a bibliographic survey on consumerism in childhood, seeking to contribute to the discussion of the theme in the educational field. To this end, the work addresses the relationship between culture and consumption, the definition of consumerism, marketing and advertising, the presentation of the definition of childhood, the influence of the media and its relationship with child consumerism, laws for the protection of children and the role of the school in this context. It is exposed that the market increasingly uses mechanisms to win over the child audience using various media and tools such as advertising, advertising and "marketing" that increase their profitability and profitability on a daily basis. Ever-changing family functioning models and easy access to new technologies make consumer education a much-needed reality for the schooling process. It is discussed that it is necessary to educate students under a critical perspective, seeking to overcome naive visions and to create more conscious habits about consumption.

Civil construction is an important indicator of a country's economic and social development, but it is also an activity that generates environmental impacts and its residues have been a major problem for society. Part of the waste generated, especially that of concrete, can be transformed into aggregates and replace part of the natural aggregates. The objective of this study was to evaluate the impacts of substituting natural coarse aggregate for recycled concrete aggregate (RCA) on the mechanical properties of concrete. The starting point was the creation of a database formed with results of compressive strength and modulus of elasticity available in the literature. These data were used in statistical analyzes that took as a reference the results corresponding to concretes with natural aggregates. The compressive strength in RCA concretes showed that the variation in relation to the reference concrete increases as the substitution content increases, the same behavior was observed for the elastic modulus. The concretes with recyclable aggregates showed great heterogeneity, with a minimum variation coefficient of 57 for compressive strength and 39 for the modulus of elasticity.

Simulations of granular flows in spouted beds are carried out following two main approaches: two-fluid model (TFM) and CFD-DEM coupling (Computational Fluid Dynamics/Discrete Element Method). Moreover, the fluid dynamics of conical spouted beds with 3.20 mm grain sorghum were evaluated through experiments, TFM simulations (2D, and 3D), and CFD-DEM simulations. The gas-solid heat transfer was evaluated by experiments and through CFD-DEM simulations. To determine the input parameters of the CFD-DEM simulations, the direct measurement approach was used. Hence, devices were built to measure the restitution, static friction, and rolling friction coefficients to account for particle-particle and particle-wall interactions. First, the simulations were conducted from operational conditions, and experimental data to validate the model obtained from the literature. Subsequently, an experimental unit was constructed and fluid dynamic and heat transfer tests were performed. The simulations were conducted using the FLUENT® software. The geometries were built in DesignModeler and the computational grids generated in Meshing from the ANSYS® package, student version 19.1. With the experimental devices and employed methodologies, it was possible to obtain the material and interaction properties, which were essential to obtain satisfactory results in the CFD-DEM simulations. The behavior of the spouted bed was predicted with the CFD-DEM coupling, such as the transition stages from static bed to stable spouting conditions. In addition, the fluid dynamic characteristic curve was successfully simulated for both experimental units analyzed. For 2D and 3D TFM simulations, the pressure drop data as a function of air velocity (fluid dynamic characteristic curve) did not show the typical behavior of spouted bed. Through CFD-DEM simulations, the effect of six cone angles (28°, 30°, 45°, 60°, 75°, and 90°) on the spouted bed fluid dynamics was also evaluated, in order to determine the configuration that favors the drying process. Smaller cone angles provide better solids circulation with higher mass flow rate, and shorter cycle times. Consistent results were also verified for the heat transfer. After reaching the steady-state, there were no dead zones in the spouted bed, and the particles temperature was homogeneous, which is evidence of the efficient gas-solid contact with this drying equipment.

The world population and demand for food are expected to have considerable growth in the next 30 years. In such case, the food could not be sufficiently supplied with sustainability. Therefore, edible insect proteins have been studied with more interest in the last years as a potential alternative source of protein to help meet such demand as food or feed. This kind of protein is more sustainable because it can be produced in small areas and systems with low emissions of greenhouse effect gases. Based on the nutritional aspect, insect proteins have a quality similar to conventional proteins in terms of essential amino acids. According to scientific data compilation, these proteins used in several preparation forms and process conditions show properties comparable with those of proteins widely used for functional purposes in food. Products prepared with partial replacement of conventional proteins by insects using flours or protein concentrates may be interesting to improve the acceptance and adoption of this novel protein source in the diet by Western consumers. Currently, insects as food are considered in the category of novel foods by western legislation, requiring prior authorization and proof of safety. This tends to change as this emerging source gains notoriety and relevance in these markets

The present study is part of the matrix project that aimed to carry out a multidimensional assessment from the perspective of different actors whose policies on schooling of students with special education needs (SEN) directly affect it. Bearing in mind that the National Education Plan recommends carrying out studies with the objective of monitoring as goals of educational policies, the objective of this study was to analyze a schooling policy for SEN student’s perspectives. The research anchored in the Policy Cycle Approach perspective had SEN students as actors. The design involved a multi-method research based on the analytical perspective that offers a possibility to interpret the information in a quantitative and qualitative way, for triangulation of results. The study conducted in a small municipality in the state of São Paulo involved 65 SEN students, (56 from elementary school cycle 1, and 9 from elementary school cycle 2) from seven schools in the municipal education system. The instruments used to collect data was closed questionnaires through the SurveyAnyPlace platform and saved in spreadsheets, generating the quantitative database and a semi-structured interview script carried out with five participants. For the analysis of quantitative data, item scoring criteria were created, which were grouped into 15 indicators and, and these in six categories. After converting the responses generated in the database to numerical data (based on the established criteria), we calculated arithmetic averages for each of the indicators, requirements and a general average for the municipality studied. We transcribed the reports obtained in the focus group and excerpts selected to illustrate and support the quantitative data. The aspects of Municipal School Inclusion Policy by Students well evaluated by the students were: 1. Participation (7.1-good), 3) Assessment of learning (6.6- good), 4) Relationships (7.1 - good) and 5) Self-assessment (8.2 - very good). The aspects that deserve more attention from the policy managers and teachers were: 2) Specific support and services (5.5 - regular), and 6)- Accessibility (5.6-regular). The general index for the municipality was good (6.3). We conclude that: a) the questionnaires used need improvement; b) the focus group technique with the students was challenging and the data were succinct due to the complexity of inciting and maintaining deep dialogues and; c) SEN students, even within the collection challenges, demonstrated that their perspectives are unique and their voices are fundamental in the elaboration of schooling policies. We expect that this study will contribute to the area of special education and that the voices of students will be heard and valued.

The soil is considered a living organism, the Agroforestry Systems are considered more sustainable production systems for the generation of food, inputs and conservation of forests and biodiversity. This study aimed to evaluate the infiltration rate, soil cover and leaf damage in Agroforestry Systems as a function of the rain seasonality. The study was conducted, in a complex, biodiverse and successional Agroforestry Systems with occasional cultural treatment and in a simple Agroforestry Systems, with cultural treatment performed periodically. In both cases, the monitoring of the infiltration rate was also carried out in control plots. The rate of water infiltration in the soil was obtained by the container method. A comparison was made between the campaigns between the rainy season and the dry season. The ground cover was verified using the 1m2 quadrant method. Leaf damage was assessed visually from two leaves collected from each of the faces (N, S, E, W) in the middle third of the individual of shrub / tree size. ANOVAs of the indicators were performed, when this was significant, the Student test was performed. TI increased by 63% in Agroforestry Systems 1 and 3% in Agroforestry Systems 2 , when compared to witness averages. In both areas, the average soil coverage was less than 50%, but it influenced the IT. Both Agroforestry Systems showed some level of leaf damage, which was positively influenced by soil cover. It was concluded that the studied Agroforestry Systems present improvements in the pre-established indicators

The drying process can be carried out by different methods, but the choice directly influences the quality of the final product, which can obviously be affected by operational conditions. This work aims to study the drying of the avocado pulp, through process optimization and experimental analysis. To achieve the proposed objective, this study was divided into two stages. Initially, the equipment to be used for drying the fruit pulp was defined. For this, the process synthesis techniques were applied, such as making the branch-and-bound trees, heuristic rules and determination the base flowchart, using the fuzzy logic method. From the application of the process synthesis, the lyophilization equipment proved to be promising for the drying process of the fruit pulp. After, considering that the knowledge of the drying rate is essential in the choice of suitable conditions for the lyophilization process, and the experimental data obtained to determine the drying kinetics, in the simplest lyophilizer, are measured in a discontinuous way, through destructive analysis, a simplest and low-cost setup for a laboratory-scale lyophilizer was developed, with an automated data acquisition system. The setup made it possible to obtain the drying kinetics curves, the temperature of the material as a function of time and the pressure difference, in addition to controlling different temperatures of the heating tray. The study was evaluated for the drying of the avocado pulp with heating temperature of 30, 40, 50 ° C and also without the supplying controlled of heat. The data acquisition system implemented proved to be satisfactory for the conditions evaluated. As expected, the load cell was influenced by the operating conditions, but the data was reproducible, so it was possible to minimize errors in the measurement of mass. The controlled supply of heat during lyophilization accelerated the process and, consequently, had a direct influence on the drying rate. In addition to the tests related to lyophilization of the avocado pulp, the influence of drying on the morphology, thermal decomposition, rehydration capacity, color, phenolic compounds and antioxidant activity of the fruit pulp was verified. It was observed that the heating temperature had an influence on the evaluated parameters, with temperatures of 40 and 50 ° C being the most appropriate for the process of dehydration of the fruit pulp. This study proved to be important for the analysis of the steps that occur during the lyophilization process.

This monograph has the general objective of this study to reflect on the existing cultural repertoire and produced by young children and educators through intangible heritage education, in order to contribute with pedagogical practices and proposals in early childhood education. It is a bibliographic and documentary research around laws and curricular documents necessary for the construction process of this work, understanding culture as an open space for the search for observation through the plurality of childhood, education heritage and cultural repertoire of the child in early childhood education. By reflecting on education heritage and cultural heritage as driving means for thinking and rethinking the history, origin and details that surround us, which often go unnoticed. Through the concepts of material and immaterial heritage, I seek to bring reflection as to their presence in the National Common Curricular Base - BNCC - on the stage of early childhood education. With a focus on early childhood, I try to find if there is a concern on the part of educators regarding the valorization of childhood cultures, from the perspective of the children's repertoires. In this way, we concluded the work with emphasis on the importance of seeing the child as a being who creates, capable of establishing multiple relationships, in order to bring into the school environment an egalitarian, playful education, which respects and dialogues with the diversity of each child and value plural childhoods.

Galls are structures formed by the modification of plant tissue by the action of agents such as viruses, bacteria, nematodes, and, mainly, insects. Most known galls are induced by dipterans of the Cecidomyiidae family. Many gall morphotypes can be found in host plants simultaneously. Their presence is a marker to identify the gall makers because there is a species-specific interaction between gall makers and host plant species. This study aimed to search for records of the occurrence of morphotypes induced by cecidomyiids in Andira Lam. species distributed in Brazil to expand the geographical distribution of gall morphotypes and, consequently, of their gall makers. The study was carried out through the search for records of gall morphotypes in Andira species in the database of scientific articles and in Brazilian and abroad virtual herbaria. As results were found records for six species of Andira, which are Andira cujabensis Benth, Andira fraxinifolia Benth., Andira humilis Mart. ex Benth., Andira nitida Mart. ex Benth., Andira surinamensis (Bondt) Splitg. ex Amshoff, and Andira vermifuga (Mart.) Benth. In addition to the distribution registered in the original description of the gall makers –which usually cover only the type-locality– two new records of occurrence were found for Andira fraxinifolia and Andira nitida each, four for Andira humilis and six for Andira vermifuga. With these new records of occurrence, there was an expansion of geographic distribution to six new locations in Brazilian states already sampled, and new occurrences to the states of Bahia, Paraíba, Goiás, Ceará and Distrito Federal.

This project aims to develop a didactic sequence that contributes to learning the concept of electromagnetic induction from the theme of wind energy. The topic is pertinent since lately there is a very strong incentive for countries to adopt a policy of generating electricity from renewable sources and causing the least amount of environmental impact. Wind energy is an abundant and clean energy source and the number of wind farms in Brazil has been growing, indicating an effort by the country to diversify its energy matrix. The educational product developed sought, based on the strategy of using a text for scientific dissemination, the exhibition of scenes from the film “The Boy Who Discovered the Wind” and a series of electromagnetism experiments, to develop activities that promote social interaction between the students and the teacher. Given the difficulties of students in understanding these concepts related to electromagnetism due to the high level of abstraction, the educational product sought, from the diversification of activities, to improve students' understanding of electromagnetic induction and its application in the generation of electrical energy.

The giftedness is not an immutable condition. They are also not conditioned by characteristics such as race, gender, ethnicity, age, or social class. Sometimes, giftedness occurs concomitantly with other specificities, such as: disability, disorders, or syndromes. In this case, it is called twice exceptionally. Seeking to study this phenomenon, the research aims to identify giftedness in adults with visual impairment. The specific objective is to verify whether the instruments applied – Questionário de Identificação de Indicadores de Altas habilidades/superdotação - Adultos (QIIAHSD-Adultos) and Questionário de Identificação de Indicadores de Altas habilidades/superdotação – Adultos – 2ª fonte (QIIAHSD-Adultos – 2ª fonte)– are effective for this audience. The research has an exploratory and descriptive approach. The study included a field diary, electronic forms related to the instruments (QIIAHSD-Adultos and QIIAHSD-Adultos – 2ª fonte) and an interview script. The research is divided into a pilot study and a main study. The pilot study was carried-out in person before the COVID-19 pandemic, in a city in the countryside of the State of São Paulo. Five people with visual impairment participated as 1st source respondents and three people as 2nd source respondents, aged between 18 and 80 years. The main study took place remotely, through electronic forms and interviews. Altogether, there were 14 participants, aged between 21 and 80 years. Results indicate that one pilot study participant was identified giftedness indicators. In the main study, four participants with giftedness indicators were identified. The data show that enabling postures negatively interfere in the development of people giftedness and visual impairment, which can make their abilities invisible. Some participants indicated that they were seen as dependent people. It was possible to verify that the school and the family have fundamental roles in the general development of these people. These factors can influence negatively, generating trauma, or positively, helping to develop high self-esteem, self-concept, and resilience. The data showed that, in the case of the women who participated in the study, there may be stigmas related to gender and disability, hiding their potential, nullifying their achievements, or reinforcing the belief that their abilities are the result of a lot of effort. The study also demonstrates that the gay person with visual impairment who has high potential suffers more than a double stigma. It is a unique condition, which can lead to developmental dissociation. From the application of the QIIAHSD-Adultos and QIIAHSD-Adultos – 2ª fonte instruments, it was verified that, although they are well elaborated and reach the goal of identifying gifted people, they have some weaknesses, including: the need of the questions aimed at the public with twice exceptionality and the adequacy of developmental concepts and specificities of typical giftedness and visual impairment people. Thus, adaptations in the instruments used in the research are recommended for future studies.
