Visual impairment classification varies from low visual loss to total absence of vision. There are many alterations in the routine of children and teenagers who suffer with visual impairment, changing their independency, the way they do everyday activities and the relationship with other people, changing their family lives too. Based on this, we found the necessity and motivation to do this research, which aims to study the experiences of visual impaired children and teenagers. This is a qualitative and descriptive research conducted in two cities, with the Symbolic Interactionism as theoretical reference. In the city A, the identification of the families was done using the data supplied by the Secretaria Estadual de Educação do Estado de São Paulo (the official government institution for education in the state of Sao Paulo). In the city B, we obtained the data from an institution for people with visual impairment; eighteen families were interviewed, and the total number of participants was 61. Data were collected using semi-structured interviews, genogram and ecomap. They were recorded and conducted in their homes or in the institution; the research was approved by the University research ethics committee number: 1.034.350. The narrative analysis was used as the methodological reference to make the interpretation of the interviews and understand the trajectory of the families. For a better comprehension, the results were divided in themes, categories and subcategories and organized in three articles for the data analysis. The trajectory starts with the perception of the first signs of visual impairment and the surprise with the diagnosis. After, the families have to adapt their routines in order to facilitate patient’s life. Among the adaptations, there is the use of treatment resources, the necessity to adapt and accept the condition, to protect and to understand the limits to overprotection. The school environment was described as difficult and traumatic in the city A. The social support received by the family may not be characterized as social network, but as a social support. For the families who live in the city B, the support from a specialized organization was essential to deal with visual impairment. We may conclude that it is necessary the qualification of education and health professionals to modify the reality of these families. This research may support improvements in current public health policies and create new ones for the inclusion of visual impaired patients

There is a wide divergence of results in the literature on the clinical relevance and the etiology of memory complaints (MC). Currently QM is being studied as pre-clinical symptom of Alzheimer's disease before a possible CCL setting. Our hypothesis is that MC may be associated with lower performance on cognitive tests or a low self-rated health. Objective. To investigate the relationship among MC in elderly patients with objective cognitive impairment and self-rated health. Method. This was a cross-sectional, correlational and quantitative study. The instruments used were the Memory Complaint Scale (MCS) - forms A and B, Addenbrooke’s Cognitive Examination – Revised (CEA-R), Mini-Mental State Examination (MMSE), Clock Drawing Test (CDT), Medical Outcomes Study 8-item Short-Form Heath Survey, Geriatric Depression Scale and a sociodemographic questionnaire. Results. Participated in this study 83 subjects, divided between the two forms of MCS evaluation scale. Sociodemographic groups were very similar, with no significant differences with MC. According to MCS-A, there was a significant association only with the CDT. MCS-B was associated with ACE-R and its domains memory, fluency and visual spatial orientation?. A ROC curve was drawn from the results of MCS-B in relation to the ACE-R and MMSE, demonstrating the high specificity of the instrument. Conclusion. In this study it was not found robust results with MC reported by the elderly and changes in cognitive screening tests. However, when the informant reported the complaint, the analysis with cognitive performance levels were more consolidated. This results highligh the need to include and empower perception of someone who knows enough the elderly to assess the MC globally.

Multiple Sclerosis (MS) is an inflammatory demyelinating (that is, with myelin loss) disease of the Central Nervous System (CNS). It is considered an autoimmune disease in which the immune system wrongly recognizes the myelin sheath of the CNS as an external element and attacks it, resulting in inflammation and scarring (sclerosis) of multiple areas of CNS’s white matter. Multi-contrast magnetic resonance imaging (MRI) has been successfully used in diagnosing and monitoring MS due to its excellent properties such as high resolution and good differentiation between soft tissues. Nowadays, the preferred method to segment MS lesions is the manual segmentation, which is done by specialists with limited help of a computer. However, this approach is tiresome, expensive and prone to error due to inter- and intra-variability between observers caused by low contrast on lesion edges. The challenge in automatic detection and segmentation of MS lesions in MR images is related to the variability of size and location of lesions, low contrast due to partial volume effect and the high range of forms that lesions can take depending on the stage of the disease. Recently, many researchers have turned their efforts into developing techniques that aim to accurately measure volumes of brain tissues and MS lesions, and also to reduce the amount of time spent on image analysis. In this context, this project proposes the study and development of an automatic computational technique based on an outlier detection approach, Student’s t-distribution finite mixture models and probabilistic atlases to segment and measure MS lesions volumes in MR images.

Nanosized NaX zeolites (FAU) (crystallite size = 16 nm; Si/Al ratio = 1,5) were synthesized and modified through ion exchange with linear alkylammonium cations containing from one to six carbons, with the intent to activate basic sites. In this work, commercial microsized zeolites (Aldrich) were also ion exchanged for comparison matters and all samples were characterized. Scanning electron microscopy analysis showed that both micro- and nanosized zeolites containing sodium portray polycrystalline particles: the former presents octahedral habit and particle size of 2952 nm and the latter presents an indefinite habit and particle size of 426 nm. Among the ion exchanged samples, none presented complete exchange of the Na+ cations due to steric hindrance. Nanosized zeolites presented higher exchange degrees than the microsized ones, which is due to higher accessibility to the exchange sites. Such factors also explain the exchange degrees’ reduction with the cations’ chain length, which is less abrupt among the nanosized samples. This happens due to the nanosized samples’ higher interparticular porosity, which has also allowed their micropore volumes’ constant decrease, differently from the microsized samples, which faced a minimum value with butylammonium. When the cations’ length is increased, the unit cell expands in comparison to the zeolites containing sodium since bulkier cations cause variations in the length and angle of the of the O-Si-O and O-Al-O bonds. Through thermogravimetric analysis in oxidant atmosphere, it was observed that the longer the carbon chain length, the lower is the mass loss, which evidences the lower diffusional limitations. The same was observed in inert atmosphere, which indicates that the presence of O2 does not influence the thermal events. Nanosized zeolites illustrate smoother mass loss profiles, which marks smaller diffusional limitations. The zeolitic materials were catalytically evaluated along the Knoevenagel condensation between butyraldehyde and ethyl cyanoacetate (3% m/m catalyst) during 1 h. The nanometric zeolites presented higher conversions and higher reaction rates when t = 0 than the microcrystalline ones, confirming the advantages of nanosized materials.

This thesis entitled "Childhoods experiences with Crop Yields in Ile Axe Omo Ibá Latam", sought to bring insights grounded in a cognitive justice perspective, recognizing children as crop producers in their social practices and tracing dialogues with theoretical frameworks and methodological Latin Americans and Africans. The guiding research question is; "As social practices of children's cultures in Ile Axe Omo x and IBA Latam constitute childhoods in Candomblé?". And the goal of "Understanding how social practices of child cultures in Ile Axe Omo Ibá Latam, unfold in educational processes and unveil new understandings and meanings on the childhood", allowed the children to bring their experiences of ancestry, corporeality and orality lived in Candomblé, through different epistemologies. The methodology was built with children and Candomblé community with inspiration in phenomenology and semiotics of communication in order to capture the different languages of children. The data are described in a comprehensive analysis building episodes through the record collected with children. Data analysis considered the possibility of establishing dialogues between the principles of world Yoruba cosmology present in Candomblé with the legal frameworks of the opinions CNE / CP / 03/2004 and CNE / CB / 20/2009 Children's Educational own. Considering the circularity present throughout the research aportada in exúlica logic is indicated possibilities for building an egalitarian education through the production of cultures of children of Candomblé.

In this master thesis, I seek to analyze the supervisor's papers and contributions of the PIBID (Programa Institucional de Bolsa de Iniciação à docência) in the various contributions of the program supervisor and implications in the continued training of supervisors. I made this study by analyze of texts presented at the V Encontro Nacional de Licenciaturas (ENALIC), IV Seminário Nacional do PIBID and XI Seminário de Iniciação à Docência (SID), held between December – days 8 to 12 – of 2014 at the Universidade Federal do Rio Grande do Norte (UFRN). Thus, the general purpose of this research is to find out what the texts publicated within event bring about the acting of the supervisors and their possible contributions in the graduated formation of students participants of the PIBID, beyond to show considerations about what the supervisors got in their formation when they participated on program. The question resulting of this goal is how is characterized the formation and the acting of PIBID supervisors within of the V ENALIC's and of the another two events publications. The theoretical grounding to this work is based on the dialogue between public policies and the production in the teacher formation area, articulating these ideas with the publications of the events. Methodologically, I made an analysis of the V ENALIC et al documents, bringing, as results, reflections about what the supervisors understand to respect their roles. The survey of the minutes found out nine texts perpetrated by supervisors: the informations’s joined of this documents, shaped of groups, categories, itens and fragments of analysis, seeks the understanding about the roles and contributions of and about the people that were envolved within the program. The survey results show that the PIBID is a program that helps on the initial and continuing teachers formation, still bringing other contributions, being the supervisor a fundamental key for program execution, combining theory and practice, beyond teaching and learning, both for work in school as in contribution for the graduate students.

The reproduction of 'urban x rural' hierarchy is filled from the stigmatizing understanding that living in rural areas is social and cultural inferior. According to this, with the increasing insertion of children from rural area to urban schools, it is inevitable that such an understanding pervades school relations, reinforcing mystified aspects about this population. If school operates as a stage of social relations and children as protagonists, how do they mean their experiences in urban school scenery? Under this question, the object is to understand how children of rural areas mean their experiences in a Municipal Elementary School, located in the urban area of a city in São Paulo. Participative observations were conducted in each part of the school and registered as field diaries, with a third grade group of eighteen children, and the classroom and Physical Education teachers. In addition to the participative observations, circles of conversation were conducted with the children. From the attentive and patient listening to the voices of them, the data analysis indicated that the school timings and spaces exceeded the impregnated speeches of stereotypical ideal to the rural subjects, because with the contact with and among children, the articulation of elements from both cultures, rural and urban, was present. Through the fluidity of affective relationships, the children showed to mean the school as a space to improve knowledge necessary for adult life, as well as a place to win friends, play and enjoy time better. It was realized in the relation of the teachers that some pedagogical deeds and practices still need to be contextualized to the reality of the children, considering them as concrete subjects, holders of childhood knowledge and skill. It is concluded that the being in school is for the children a possibility to build up shared and permissible practices of creation and re- signification of experiences, especially away from adult eyes.

Fructose (1,3,4,5,6-pentahydroxyhex-2-one) is an important sugar in global market because its unique characteristics when compared to another sugars. It becomes the fructose economically attractive besides the fact that it is not easily produced. Fructose may be produced by crystallization from its aqueous solution adding ethanol as antisolvent, and afterward a separation process will be necessary to separate ethanol+water+fructose to become the process practicable. Applying this way, ethanol may be recovered using a distillation column and vaporliquid equilibrium data for water+ethanol+fructose mixture are necessary but it is not available in literature yet. Thermodynamic models are necessary to modelate a distillation column. Thus, this work has the objective of obtain VLE of hydroethanolic solutions contain fructose, and estimate parameters of an adequated model to describe the behavior of the mixture. In this work, Vapor-liquid equilibrium (VLE) data for water+ethanol+fructose and water+ethanol were determined using a modified ebulliometer based on vapor recirculation operating at atmospheric pressure of São Carlos. The composition was determinated combinating measures of refractive index and mass balance. Curves of VLE with fix composition of fructose containing 10.3%, 20.7% and 31.0% in mass were determinated, besides a binary curve with water and ethanol to validate the method. The estimative of parameters was realized in Scilab software version 5.5.1, utilizing the Levenberg-Marquardt method. The experimental data were used to estimate parameters of models based on excess Gibbs energy and local composition (Wilson, NRTL, UNIQUAC, P&M-UNIQUAC). Among all the model tested on estimative of parameters, the best model to describe the experimental data was the P&M-UNIQUAC model whose parameters were considered dependents of temperature with maximum deviation of 6,10% to water in vapor phase. Were evaluated models based on modifications of UNIFAC model, in these cases using parameters of interaction available in literature, to these cases the best model to describe the experimental was the mS-UNIFAC with maximum deviation of 14,45% to water in vapor phase. The results show that is possible determinate VLE data contain fructose utilizing the methology adopted and that fructose influences in VLE.

Our object of study is a videoclasses service (videoaula@rnp) over the Internet, maintained by the National Network of Education and Research (RNP). To approach it will use the Actor- Network Theory. We propose here to look at the crossings between software, public officials and laboratories. The software available for publishing videoclasses by RNP is a Free Software called RIOComposer. This has become a link between free software and distance education. Obviously, this link is not given in a simple way and involves, on our part, a study of the Free Software and the RNP. Besides that, the movement of some laboratories involved with the creation of RIOComposer and other solutions for distance education will be observed. We will monitor the principles that guided the first Free Software developers, as their initial consequences. For that, some authors of social sciences, who proposed to examine the Free Software, will be used. About RNP, we will deal with its various initiatives involving the spread of high-speed networks for the Brazilian academic community and the development of solutions in Information and Communication Technologies. The selected laboratories will be seen in its relations with the Free Software and RNP.

Currently higher education institutions are under pressure given to the current demand for innovation of their efforts, not only in the context of research, but also in relation to education. The technological context for the insertion of digital technologies as a way to improve teaching and learning contents, procedures and attitudes are increasingly promising with the possibility of making them more suited to the reality that surrounds students. However, how teachers have appropriated these technologies for teaching in order to help their students in the construction of knowledge? Facing this question, this paper aims to investigate how music teachers of a higher education federal public institution utilize an electronic educational game as a music education tool. This work also falls within the framework of the discussions on how teacher training deals with Digital Technologies of Information and Communication, proposing an investigation of how these technologies are presented or taught during the process of teacher training, both in initial training and continued education proposals. The research methodology's focus is qualitative and descriptive. Data collection was based on empirical sources obtained from semi-structured interviews with music education teachers working in higher education at the Federal University of São Carlos (UFSCar). In addition to the analysis of data from the interviews, it was also intended to follow practical applications of the educational game Musikinésia, which could be explored into the keyboard classes of Bachelor of Music course from UFSCar as a resource that helps the students to learn the instrument keys. The results of these applications showed that, in fact, a game can bring learning benefits to students, however, it was also witnessed some difficulty by teachers in dealing with this technology, which alerts us to rethink how the preparation courses degree are training future teachers to think critically when it comes to digital technologies.

The woman´s access to higher education and academic career is na achievement. More and more women occupy the graduation chairs, getting to many areas of knowledge, occupying more than half of the places offered. But the number of women found in the highest scientific career positions remains low. What happened along this career path that prevents women able to ascend vertically? The glass ceiling assumption seems to define the force that keeps women in lower hierarchical positions. The glass ceiling is formed not by one, but by many barriers and obstacles that add up acting often in the loss of women throughout their careers. This work seeks to understand a little of the professional lives of researches who managed to get to a privileged elite of science, the "National Counsel of Technological and Scientific Development" – CNPq grant recipients in research, with the intention to diagnose the nature and impact of gender differences throughout the scientific career. From this point is possible to draw up suggestions for actions that seek to provide an institutional environment with equal opportunities for both genders.

Counting the number of leukocytes present in the blood vessels is an important task to understand inflammation mechanisms and to assess the effects of drugs that are being developed for the treatment of inflammatory diseases. In general, leukocyte counting is done by an observer (laboratory technician or specialist) using a sequence of intravital microscopy images obtained from blood vessel of an animal testing. However, this procedure is time-consuming, prone to errors, due to visual fatigue of the observer, and biased, due to inter and intra-observer variability. Thus, the objective of this work was the development of computational technique for the automatic detection of leukocytes in intravital video microscopy images. For this, the detection of leukocytes was performed in two main stages. In stage 1, the phase congruency measure, which is invariant to changes of contrast and lighting images, was used to calculate a blobness measure used to detect circular structures in intravital microscopy images. In stage 2, the circular structures detected in stage 1 were analyzed locally to identify only those corresponding to true leukocytes. The results were evaluated using the precision, recall and F1-measure metrics and the area under the precision-recall curves. Furthermore, the proposed technique was compared with the template matching technique.

We study fractal subordinacy theory for one-dimensional Schrödinger operators. First, we review results on Hausdorff subordinacy for discrete one-dimensional Schrödinger operators in order to analyze the differences and similarities of these results with respect to the packing setting. By using methods of packing subordinacy, we have obtained pac- king continuity properties of spectral measures of such operators. Then, we apply these methods to Sturmian operators with rotation number of quasibounded density to show that they have purely α-packing continuous spectrum. Moreover, we show that spectral fractal dimensional properties of discrete Schrödinger operators with Sturmian potentials of bounded density and with sparse potentials are preserved under suitable polynomial decaying perturbations, when the spectrum of these perturbed operators have some singular continuous component. Finally, we performed an introductory study of fractal subordinacy for continuous one-dimensional Schrödinger operators defined in bounded intervals.

Global phenomena such as population aging, increased rate of disability, and growing numbers of obese people have gained intense attention within the air transportation industry since it expects increases in travel and changes in the profile of users. However, studies have indicated gaps between the needs of passengers and the services and assistance provided by airlines and airports. Therefore, the objective of this study was to understand the contradictions and discontinuities in the activity systems of passengers with disability, elderly and obese in the Brazilian air transportation originating restrictions to participation during the flight and during the boarding and deplaning process of air travel. In the present study, a qualitative approach was adopted based on Ergonomics and the Activity Theory. The research participants were passengers with physical, visual, and auditory disabilities and elderly and obese passengers. A combination of methods and techniques was used for data collection, including: 14 preliminary interviews in health care organizations and facilities that provide assistance and services for the participant groups and air transportation users, with a total of 25 participants; a questionnaire survey involving 399 respondents; and observations in commercial aviation. A total of 43 non-participant observations were carried out, and other eight participant observations took place during the journey, which included two self-confrontation interviews. The results indicated passenger participation restrictions during the journey affect attitudinal barriers and limited spatial accessibility that are related to airport infrastructure, airport signs, operational factors, equipment, aircrafts, and regulatory aspects. These restrictions are related to contradictions in the interaction of the components of activity system, which include: the passenger, the artifacts, the rules, the community (passengers and workers), the airport operators, and the airlines, and the object of the activity. It was found that, in order to face these difficulties, passengers employ personal and interpersonal strategies. Therefore, specifications were developed to change the contextual factors associated with the environment, equipment, and operations. To promote full participation during the air journey, some changes are needed; primarily transformation in significance and representations for action of people involved in the air transportation and their work activity, seeking to achieve integration between design and use. This study was carried out focusing on the activity, which contributed to the involvement of different social actors; thus the information provided is based on the learning gained from experience and interaction with the subjects and the context aiming to demonstrate the users’ needs and constraints and support new air transport developments.

This Master's degree research aims to analyze the perception, reception and evaluation of students and the teacher-researcher regarding activities employed from the perspective of Critical Literacies. Theoretical aspects are based on authors like Monte Mór (2008, 2014, 2015), Lankshear and Knobel (2003, 2007), Duboc (2012, 2014), Duboc and Gattolin (2015), Kalantzis and Cope (2008, 2012), Rojo (2009, 2012), Janks (2012, 2013), Janks and Vasquez (2011), Freire (2011), Cervetti et. alii. (2001) and Jordão (2010; 2014), who report the possibility of developing critical features and agency of individuals accounting for the local context. Besides, we seek for understanding considerations about the post-method through Kumaravadivelu (2006) and Abrahão (2009) in order to analyze participants' autonomy development and issues related to teaching practices. Furthermore, we search to find focal points between the two perspectives mentioned before. Considering the qualitative nature of this study, it is under the methodology of a research-action according to Burns (1999; 2010) and Viana (2007), as it takes place in an environment in which the teacher rethinks her practice. The tools used were: survey, aiming to profile and understand the interests of students; the record book of the teacher-researcher, self-evaluation sheets and audio recording of the lessons. These tools enable us to observe the perception of the participants about teaching units, the progress of activities, the attitude of the teacher-researcher, the gaps that took place in the classroom and the curricular attitude of the teacher-researcher before these gaps. The research was carried out at a State Language Study Center, in the state of São Paulo, located in a public school in a small town in the countryside. The organization and analysis of data allowed a reading which indicates the strategies used by the teacher-researcher to improve Critical Literacies and we observe: a) material elaboration; b) perception of the gaps; c) curricular attitude and d) autonomy/agency development. Also, it was possible to observe the improvement of critical features in some participants and as they found it strange, they deconstruct and took different positions as from the discussions regarding the proposed themes.

Population aging is a global phenomenon related to changes in family structures and functions that bring consequences to the elderly, such as: change in living conditions, challenges in the care and social support, among others. This study aims to analyze the relationship between care system, social support and the fragility of senior caregivers in the context of high social vulnerability. It is an exploratory and analytical study, using the quantitative method of investigation. The population analyzed consisted of people aged 60 or over, who takes care of the seniors and were registered in the ”Unidades de Saúde da Família” (Public Family Health Units) in a city in the state of São Paulo and who are under the care of “ Núcleo de Apoio a Saúde da Família (NASF)” (Center for Support for Family Health), in the region of ARES “Cidade Aracy” (Aracy City). Interviews were conducted in the homes of elderly caregivers and used the following instruments for data collection: Semi-Structured Interviews, The Addenbrooke's Cognitive Examination Revised (ACE R), Geriatric Depression Scale (GDS), Fragility Assessment according to phenotype Fried, family APGAR, Genogram and ecomap. Most of the caregivers are spouses (83.6%), carefully time 1-4 years (46.5%) and spending one to four hours taking care (52%) of the elderly. The most mentioned institution that assists these seniors was a health institution. The main care provided to the elderly was feeding (82.2%), followed by lead to medical appointments (63.6%). There was a statistically significant association of low-income seniors with worse cognitive performance and the negative influence of the largest number of people living at home with worse results in cognition test. It is necessary to investigate the profile of these caregivers, as most are pre-fragile, and takes care of another pre-fragile elderly. It is noteworthy that the vast majority of the elderly in this study lives in houses with a large number of people, which is common in the context of high social vulnerability and low education; it was found that this factor interferes in the cognitive performance. More studies are necessary in order to investigate the conditions offered by the society and what these seniors, families and their social network can do in favor of a healthy aging.

This study consists in the synthesis and characterization of gas sensors based on hexagonal sodium-tungsten bronze powders (NaxWO3+x / 2.yH2O), whereas the gas sensors were synthesized by two routes. Both used as acid precipitation method in a sodium tungstate dihydrate solution (Na2WO4 • 2H2O). The routes were different by heating systems and in the first route obtained by the microwave-assisted hydrothermal method (HM). The second one was a hot plate with a magnetic stirrer (HP). Both syntheses were very efficient from the point of view of energy expenditure, because we obtained the NaxWO3+x/2.yH2O in short time and low temperatures. Samples were characterized by means of Raman spectroscopy, Fourier Transform Infrared (FTIR), absorption in the ultraviolet and visible region (UV-Vis), photoluminescence and energy dispersive X-rays (EDS), X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The bronze sensors obtained were tested against NO2 and the samples prepared by both routes were proved to be sensitive to gas. The HM samples had a higher sensitivity (Rgas / Rar ≅ 7 for 100 ppm of gás) and response time (of 1.5 minutes), with a working temperature of 250 ° C. On the other hand, the samples obtained by the PA method had the advantage of operating at working temperature of about 150 ° C, but with lower sensitivity and with a greater response time and recovery time (≅ 10 minutes). From the analysis of the photoluminescence measurement, it was possible to observe some possible relations between the type of defect as well as the sensitivity. It indicates that the larger the contribution of shallow defects in the samples, the greater sensitivity. It is suggested, therefore, from these data, that the sensor property in NaxWO3+x/2.yH2O system can be improved by the control of the defects.

We present a study of rank-one perturbations of self-adjoint and unitary operators, in particular related to the so-called Kotani’s trick. In Chapter 2 we recall relevant definitions and elementary facts. In Chapter 3 we present recent results by Marx, which involve self-adjoint operators and Hausdorff measures. A generalization of such results to the set of unitary operators is described in Chapter 4.

Published in 1979, the work Florbela Espanca: vida e obra, by Agustina Bessa-Luís, shows itself as a complex characterization text to fitness in a unique literary genre, due to compose, in a first aspect, a narration of life. However, it is clear that it is not just from a pure character and simply biographical, suggesting a fluid possibility between referentiality and fictional categories. For this, the presented concerns revolve around the question how Agustina’s work feed in a hybrid communion of different textual categories. Our interests are, also, observe how this kind of genre complexity is an occurrence in author conception, mainly in the Portuguese scene after the Revolução dos Cravos placing it thus in line with female authors, allowing a contemporary work analysis, in addition to their compliance with certain neobarroco procedures that approaches the textual structure to a kaleidoscope image and its effects in the whole composition.

The development and maintenance of vocal verbal repertories that follow structural regularities are processes in need for investigation under the selection by consequences paradigm. The present study investigates the effects of presenting vocal models in passive voice and explicit consequences, of high and medium preference, contingent to descriptions in active voice on the verbal voice of descriptions of Brazilian young children, 4 years old on average. Three experiments were performed. In the first, four children participated. The experimental procedure was composed by five conditions. In the first one, 10 drawings, with two animals interacting, were presented and its descriptions asked. In the second, experimenter and participant alternated in describing 20 drawings, the experimenter always described in passive voice. The third condition was similar to the second, except that descriptions in active voice (divergent) were followed by preferred consequences. The fourth condition was similar to the first one. The fifth condition was similar to the fourth, but it was conducted by an unknown experimenter. All participants described in passive voice after being exposed to the model and continued doing so even when preferred consequences followed descriptions in active voice. But the experimental design may have created a sequence effect between the second and the third conditions. Such limitation was followed in a second experiment. Other four young children participated, 4 years old on average. The procedure was similar to the first experiment, but, the model in passive voice during the second condition was replaced by the presentation of preferred explicit consequences contingent to active voice descriptions. All participants described in passive voice after being exposed to the model, except one. In order to refine the investigation, a third experiment was conducted. Other four young children mean of 4 years old, with different degrees of model following participated. The procedure was identical to the second experiment, but a pre-experimental condition was added in order to measure the participants’ sensibility to the model. Nevertheless, all participants described in passive voice after being exposed to the model in the third experimental condition. The findings point to the importance of investigations on non-arranged contingencies of reinforcement in the development and maintenance of verbal vocal repertoires that follow structural regularities.
