Acrylic resins are very used in dentistry to dental restorations and manufacture of prostheses. New compositions of acrylic resin have been developed through the incorporation of silver nanoparticles due to the antimicrobial potential. In this study, silver nanoparticles were synthesized and employed in the preparation of nanocomposites with polymethylmethacrylate (PMMA). PMMA-Ag nanocomposites were synthesized and characterized by structural, thermal, mechanical and biological techniques in order to evaluate the influence of these nanoparticles on the physicochemical properties of the new formed materials. PMMA-Ag nanocomposites were synthesized with the addition of 0.05, 0.5 and 5% (l/l) of silver nanoparticles in the polymer during the plastic phase. Possible interactions between nanoparticles and polymeric matrix occurred through the carboxylate ions, resulting in a gain in the thermal stability due to the barrier effect, which slows down the degradation of nanocomposites. The nanocomposites showed a heterogeneous distribution of spherical particles in the polymeric matrix. The mechanical tests showed the nanocomposites presented low storage modulus, loss modulus and tan δ values, which are characteristic of materials which exhibit an interfacial interaction between inorganic nanoparticles with polymer matrix. Clinically, the nanocomposites can be applied in dentistry, according to the normative American Dental Association (1958), through its specification No. 12 and ISO 4049, which evaluate the mechanical properties of dental materials. These results showed statistically are not difference between nanocomposites and the polymeric matrix. The microbiological adhesion test of PMMA and its nanocomposites to combat Candida glabrata revealed the nanocomposite with a lower percentage of colloidal solution have higher fungicide activity.

The Munich Model of Giftedness unites individual and environmental characteristics in a single scheme for the identification and development of giftedness and talent (G&T). In this model, natural abilities are called predictors, individual and environmental variables are called moderators and measures of observable talent are called criteria variables. There are seven predictors in the model that reflect the domains for G&T, intellectual abilities, creative abilities, social competence, practical intelligence, artistic abilities, musicality and psychomotor skills. In this thesis, the goal was to design a scale for the identification of G&T characteristics in students in their 4th, 5th and 6th years of primary school, through teacher nomination, as well as analyze their evidence of content validity, internal structure validity, reliability and convergent validity. To achieve the proposed goals, a series of four studies was performed: construction of the scale items; investigation of evidence of content validity based on specialists’ analyses; investigation of evidence of internal structure validity and analysis of internal consistency through teacher nomination, and investigation of evidence of convergent validity based on the correlation with the Raven's Progressive Matrices, in a sample of students. The 120 initial items of the scale were based on predictors of the Munich Model of Giftedness and complementary theories that helped in defining domains. The experts evaluated these items and proposed changes in some items, while others were excluded for not exceeding a minimum ratio of interjudge agreement. The second version of the scale consisting of 98 items, was applied to 16 teachers of 4th, 5th and 6th year primary school students which evaluated 433 students. The results of the factor analysis from this application indicated that the scale has a well-defined three-factor structure that encompasses items from the seven predictors of the model, which explains 54.8% of the total variance. The internal consistency of the instrument and for each three factors can be considered good to excellent. The scale scores also presented moderate to strong correlations with the Raven's Progressive Matrices, providing evidence for the convergent validity of the instrument. Despite the satisfactory results found, further studies are needed to increase the representativeness of the participant sample, and of the analysis for standardizing the instrument in order to conduct analyses to establish norms for interpretation of scores obtained using this instrument.

Since the Brazilian National System of Conservation Units, the society participation in management of protected areas (PAs) is guaranteed and emphasized as an important issue. Environmental education (EE) contributes to the PAs so that they can ensure biodiversity conservation, being present in actions with visitors and the surrounding population and in management processes in order to make them participative. In this context, this research studied the Fontes do Ipiranga State Park (PEFI). The PEFI is a different PA, because inside its area there are institutions such as the São Paulo Zoo, the São Paulo Botanical Garden and the Cientec Park, responsible for visitation in the area. Thus, the research objectives were to understand the development and implementation of educational activities in the institutions at PEFI; identify the participation of local communities in activities at the PA; identify the perception of managers, educators and local communities towards PEFI; and support for the preparation of an integrated educational project, using participatory methodologies. The research had a qualitative approach with data collection conducted through interviews with educators responsible for the EE programs of the institutions at PEFI, people from local communities and managers, as well as from the direct observation of the PA council meetings. In a second step, we held a meeting with the research participants, using the Café ComPartilha methodology (based on World Café methodology), to stimulate dialogue between these people and carry out analyzes of the EE described in the management plan and the implementation of an integrated EE program. The main results of the research were that, regarding the perception about PEFI, most people do not see the PA as a whole; they see the institutions at PEFI as different matters and not related to the PA. Nevertheless, people from local communities have positive perceptions towards PEFI, such as a concern for its conservation. The participation of local communities exists only through representation on the PA management council. The population did not effectively participate in the elaboration and updating of the PEFI's management plan until the moment when this survey happened. EE activities currently in operation do not have people from local communities as their main public, they are developed individually by each institution and focus only on their visitors. PEFI is not the main theme hardly in any of the activities, being more present in a museum at São Paulo Botanical Garden and in an exposition at São Paulo Zoo. The PEFI’s managers are not involved directly with the EE programs that take place in the area; this is a responsibility of the institutions that develop them. The search for the integration of educational activities at PEFI is not a clear element in the management plan, which offers no tools for its realization; in addition, there are political barriers to the implementation of an EE integrated program. However, people involved in this research showed interest in that, suggesting that the formulation of the activities should be performed collectively, including institutions, managers and people from local communities. Finally, the lack of an identity of PEFI as a PA proves to be the main factor influencing the dynamics of activities that occur in the area. This factor can be mitigated from greater dialogue between the different groups. We hope that the research will help strengthening PEFI, mainly through EE, in order to ensure its conservation.

ADAM10 is an-secretase that cleaves APP in the non-amyloidogenic pathway, thereby inhibiting -amyloid peptide (A ) production in Alzheimer´s disease (AD). Studies have shown decreased ADAM10 platelet levels in AD patients as well as the deregulation of microRNAs (miRNAs) related to molecules involved in the pathophysiology of this disease. The objective was to verify and compare ADAM10 gene expression and micro-RNAs (miRNAs) between AD patients and controls without cognitive impairment. It is a comparative study, based on the assumptions of quantitative research. Biological samples were collected, analyzed and stored in a biorepository. The ADAM10 gene expression in whole blood was studied in 47 AD, 32 healthy controls and 21 mild cognitive impairment (MCI) subjects by RT-qPCR techniques and analyzed by relative expression by 2- Ct. For miRNAs analyses, using MegaplexTM and MirWalk 2.0 database, were analyzed by RT-qPCR ~700 miRNAs in total blood and 21 miRNAs of them were validated in a sample of 21 AD subjects and 17 healthy controls. Statistical association tests, regression and diagnostic accuracy were performed. No significant differences in ADAM10 gene expression were observed between AD and control groups. Therefore, the decrease of ADAM10 protein in platelets of AD patients was not caused by a reduction in mRNA encoding for ADAM10. Mir-144-5p, miR-374 and miR-221 were downregulated in AD subjects, with moderate accuracy diagnosis. However, the association of selected miRNAs expression and Mini Mental State Examination (MMSE) was significantly better as a diagnostic tool compared to their expression separately. The validated miRNAs are involved in the regulation of pathways related to neurodegenerative diseases (beta-amyloid cascade, ubiquitination, transcriptional regulator, synaptic transmission, vesicle trafficking). Specifically, miR-144-5p, miR-374 and miR-221 are relevant for AD, as regulators of APP, BACE1 and ADAM10 translation. To the best of our knowledge, this is the first study to demonstrate a downregulation of these specific miRNAs in total blood of Alzheimer’s disease patients, compared to healthy cognitive controls. These findings are in agreement with AD protein outcomes and place the miRNAs evaluated as potential biomarkers that can be used to improve AD diagnosis.

With the rise in life expectancy and the high incidence of chronic degenerative diseases among the elderly, there is a growing demand to dedicate time to caring for an elderly family member. Caring for a dependent elderly person requires the acquisition of skills that are specific to this context, such as social skills (SS), which affect the wellbeing of the caregiver and the elderly care recipient. Given the situation-dependent nature of SS, it is important to be able to identify deficits in caregivers’ SS, but no instruments for evaluating SS in this population were found. Thus, the aim of this thesis was to develop an inventory of social skills for family caregivers of the elderly, and to analyze its psychometric properties. A review of the literature on the use of social skills among caregivers for the elderly is presented in Manuscript I. Based on a literature search using the major Psychology databases, nine studies (seven articles and two dissertations) were found, four about intervention evaluations and five reporting correlations for social skills with burden, stress, self-esteem, social support or quality of the relationship. According to the evidence, caregivers with a better-developed SS repertoire have more positive perceptions of their quality of life. In addition, although there are instruments to assess SS in other contexts, none were found for family caregivers of the elderly, in Brazil. Thus, it was concluded that it would be important to construct an instrument for this context, to assist in the identification of SS deficits, in this population. In Manuscript II, the objectives were to ascertain the primary conflicts that arise when caring for an elderly family member and identify the SS considered as important in this situation, to obtain information for preparing items for a new instrument. Interviews were conducted with 50 caregivers of the elderly, 25 elderly care-recipients and 25 professional in the field of aging. The main conflicts involved difficulties to reconcile differences of opinion, or financial issues. The SSs considered most useful included: expressing positive feelings, controlling aggressiveness, and discussing problems. Based on this information, 37 items were written, creating an initial version of an instrument to evaluate the social skills of those who care for elderly family members (IHS-CI). In Manuscript III, the aim was to describe the initial steps in the validation of this instrument. In Study 1, five independent judges conducted a semantic and content analysis of the instrument, resulting in the exclusion of six items. In Study 2, to obtain evidence about the psychometric properties of the new version of this instrument, 205 participants, all of whom cared for an elderly family member, completed the IHS-CI and a further five measures. Based on an analysis of the internal structure of the instrument, three factors were identified: Expression of emotions, Assertive communication, and Information seeking. The global, internal reliability of the instrument was excellent (α =0.886). Scores on the IHS-CI were positively correlated with greater quality of life and positive caregiver-elderly care-recipient interactions, and negatively correlated with burden, depression and conflicts. Additional studies are needed to gain further evidence of the validity of the IHSCI and to establish norms for the interpretation of test-scores. After this, the instrument will be ready for use to evaluate the social skills of family caregivers of the elderly, to guide interventions that can contribute to the greater wellbeing and quality of life of caregivers and of their elderly care-recipients.

This study aimed to investigate the physiological and somatic changes evoked by chronic stress regimens in adolescent and adult rats, with a focus on cardiovascular function. Additionally, we evaluated the long-term changes induced by stress exposure during adolescence, as well as a possible vulnerability to effects of stress in adult animals exposure to chronic stress during adolescence. Male rats were exposed to repeated restraint stress (RRS) or chronic variable stress (CVS) during adolescence (28 days) and/or adulthood (60 days). Adrenal hypertrophy, thymus involution, and elevated plasma glucocorticoid were observed only in adolescent rats, whereas reduction in body weight was caused by both stress regimens in adults. CVS increased blood pressure and heart rate regardless of the age, whereas RRS increased blood pressure selectively in adults. Resting tachycardia evoked by CVS was associated with increased cardiac sympathetic tone in adults while a decreased cardiac parasympathetic activity was observed in adolescents. Changes in baroreflex function were evoked by both RRS and CVS, but this effect was age- and type-stress specific. The pressor response to systemic administration of a α1-adrenoceptor agonist was increased by both stress regimens in adolescents. Depressor responses to acetylcholine and the nitric oxide donor sodium nitroprusside were affected by RRS in both ages. Except for the circulating glucocorticoid change, all alterations observed during adolescence were reversed in adulthood. However, the RRS or CVS in adult animals subjected to the respective chronic stressor during adolescence evoked responses that was not identified in animals exposure to the stressors only in adulthood, including: CVSevoked increase in circulating corticosterone, adrenal hypertrophy, RRS-evoked increase in heart rate and cardiac sympathetic activity, reduction of intrinsic heart rate by CVS, and baroreflex changes evoked by both stressors. These findings suggest a stress vulnerability of adolescents to somatic and neuroendocrine effects regardless of stress regimen. Our results indicate an age- and stress type-specific influence in stressevoked cardiovascular/autonomic changes. Data suggest minimal consequences in adulthood of stress during adolescence, but indicate that stress experience during adolescence causes a vulnerability to neuroendocrine and cardiovascular effects of stress in adulthood.

Theory of Mind is conventionally defined as the ability to understand and make inferences about one’s own mental states (i.e., desires, intentions and beliefs) and those of other people, and based on this repertoire, one can predict and explain human behavior. Recent research, supported by Relational Frame Theory (RFT), has emphasized the role of perspective taking in the development of Theory of Mind. Results suggest that children who undergo perspective-taking training show improved performance in Theory of Mind tasks. The goal of the present study was to administer the Perspective Taking Protocol, used in these previous studies, in Brazilian children with low performance in theory of mind tasks. Three studies were conducted, two of them being pilot studies, which revealed the need for adaptations to the original procedure. Study 1 aimed to test the original protocol with one child aged 4 years and 9 months. The protocol consisted in the presentation of blocks of simple verbal trials and trials including reversal and double reversal of roles with the experimenter. Trials included the deictic frames I-YOU, HERE-THERE and NOW-THEN. The protocol, however, proved to be incompatible with the child’s repertoire, that is, he did not meet the learning criteria established in the original study. In order to test the difficulty level of the protocol, in Study 2, two young university students received the same training. Data suggested that the two adult participants succeeded in completing the protocol, having met criteria; however, they did face difficulties during the procedure. In Study 3, four participants, aged 4 and 5, were administered an adapted version of the protocol. In order to train reversed trials, physical tips (i.e., cards) and gestural signs were used and were gradually withdrawn until participants could respond without any assistance. Participants were also evaluated in three tasks of Theory of Mind, before and after the teaching procedure. During training, children were able to respond correctly on the reversed trials, even after removal of physical tips. All four participants showed improved performance in Theory of Mind tasks after training, with scores 1 or 2 points higher (scores could vary from 0 to 3), in comparison to pretest. Results suggest that, despite the evidence showing that the Perspective Taking Protocol is effective, it should be altered in order to be consistent with the repertoire of children with quite distinct characteristics from those who participated in the original study. In the case of children participating in the present research, changes in the distribution of trials throughout training blocks, as well as changes in the format of those trials had a positive learning effect. We hope the results of the present study may encourage future work on the potential benefits of procedures aimed at perspective taking training, in particular, with individuals who present delays or difficulties in social cognition.

The cement industry, closely associated with the global warming question, accounts for significant emissions of CO2 and other air pollutants, such as SO2 and NO2 in the atmosphere. In search for ways to mitigate the atmospheric CO2, we performed semicontinuous cultures of Chlorella sorokiniana under phototrophic conditions to test the effect of a flue gas simulation (18% CO2, 9% O2, 300 ppm NO2 and 140 ppm SO2). This was provided once a day in six serial experiments, in which the exposure to the gas was increased through the increase of bubbling time. A constant flow rate allowed us to calculate the total volume of gas introduced into the system each day (0.1, 0.3, 0.8, 1.5, 6 and 48 L). Air-CO2 (18%) was used as control and its bubbling time was pHregulated. Culture medium acidification led to suboptimal growth conditions that affected cell density, photosynthetic activity, cell viability and the biochemical composition of C. sorokiniana. Compared to control, the specific growth rate decreased by 17 and 3,9% in cultures that received 6 and 48 L gas d-1, respectively. The pulseamplitude modulated (PAM) fluorometry was used for culture evaluation. It revealed low maximum quantum yield (ΦM 0.40) and operational quantum yield (Φ'M 0.47) values one day after 48 L gas bubbling. Light saturation curves confirmed the negative effects of long-time gas simulation stress. On the other hand, quenching analysis indicated an increase in photochemical light use and low values of non hotochemical quanching (qN and NPQ). Exposure of the cells to the flue gas simulation resulted in lower cell viability compared to control. Biochemical analysis showed that 6 and 48 L gas d-1 significantly increased protein content by 75% and 154%, respectively; total carbohydrates also increased in the presence of the gas, 148% and 195%, respectively. Despite the physiological changes, C. sorokiniana resisted suboptimal growth conditions imposed by the gas, supporting its vigorous nature and relevance in biotechnological aplications with flue gases.

The food security issue has entered the public agenda after the World War II, when some countries started acting to eradicate poverty and hunger (SIMON, 2012). In Brazil, the issue became relevant after 2003, when the government made some policies to end the hunger as well as poverty, like the Programa de Aquisição de Alimentos (PAA). Thus, this research aims to analyze the possibility of the implementation of PAA in Companhia de Entrepostos e Armazéns Gerais de São Paulo (CEAGESP), which is a public company responsible for storage services and wholesale food market in São Paulo state. The analysis was first focused on the Ceasa Araraquara unity, as a diagnosis which can be applied on the other unities later. Therefore, some interviews were conducted with the managers of some CEAGESP's unities along with secondary data. The theorical referential was based on the Strategic Action Fields, to understand the power relations inside the fields of food secure. To lead a better understanding of the food secure policies it was made an historical analysis of the issue, first in a worldwide context and later in a national level. Finally, the results show primarily that the operation of the PAA by CEAGESP finds some barriers within political issues. Once those questions are overcome, it will become possible for the public company to execute the policy.

Locative verbs establish a locative relation between an object and a location and are very frequent in different types of texts. This thesis aims at describing the phenomenon of locative verb constructions in Portuguese and contrasting two recent studies on the syntactic-semantic classification of these constructions carried out for Brazilian and European Portuguese. This contrastive analysis presents not only the classes of locative constructions already determined, but also the intersection and divergence points between the two variants of the Portuguese language. The data here described is expected to contribute in the construction of language resources, which could be used in several didactic applications and in natural language processing.

Many pharmaceutical solids are able to adopt more than one crystalline form, and this property is called polymorphism. Currently 80-90% of the drugs are marketed as in solid forms and a very common problem is the low solubility of these drugs, particularly in aqueous media. Depending on how a drug crystallizes, its physical and chemical properties can be changed, which may also result in changes in its solubility. Before this problem the crystals engineering appears as a strategy to improve the properties of the solid state related to the efficacy of the drugs through the development of new crystalline forms. Multicomponent molecular crystals can be prepared from supramolecular synthons forming approach by crystallization methods involving the optimization of conditions for the formation of these novel crystalline forms. In this context, this study aimed to use the solid state NMR for study of supramolecular chemistry the three antiparasitic drugs (secnidazole, albendazole and mebendazole) and one antiretroviral (tenofovir disoproxil fumarate) using a set of one-dimensional techniques (CP-TOSS, CP-NQS and CP-PI) for the carbon-13 and nitrogen-15 nucleus as well as two-dimensional (1Hx13C FSLG HETCOR). Solid state NMR was used as the primary analytical tool for characterizing the crystalline forms obtained in this study, as in the prior characterization of Active Pharmaceutical Ingredient (APIs) used as raw material, being demonstrated the applicability of this technique in the analysis of new formulations. The data obtained were of great importance in the study of these solid dosage forms which can contribute to the structural study of dosage forms, identify polymorphic forms of drugs, detect phase transitions in both API as in commercial samples and check for interactions molecular (intramolecular and intermolecular) by means of two-dimensional NMR. In this work it was shown that this technique is configured as an important tool for the characterization of new polymorphs but they certainly should be applied in conjunction with other techniques in order to take advantage of the complementarity provided when different techniques are used in combination. This work intends to consolidate the use of NMR in the solid state in Brazil as a tool for the characterization of the crystalline forms of drugs and also for the analysis of drugs, which has been few explored so far.

Due to the complexity of markets and intense competition organizations are looking for new ways to generate sustainable competitive advantage, that it is the competitive advantage that can not be copied in the short term by competitors. In this sense, the distribution channels emerge, which are the set of interdependent organizations involved in the process of making a product or service available for use or consumption. Integrating the distribution channel as intermediaries are wholesalers and retailers, who act as an important link between the industry and the end consumer. In general, these organizations carry out a number of elements of the marketing strategy in the distribution channel and so develop and maintain long-term relationships with partners and other channel members. The objective of this research is to identify how the elements of the marketing strategy influence on the aspects of the relationship. This study has as its core the wholesale distributor perspective, but also identifies the views of small food and retail industry. This research has qualitative and exploratory nature character, using as main methods the case study and the technique of critical incident. As a data collection instrument, we opted for the construction of semistructured in order to support the conduct of interviews. nine interviews were conducted, two in the distributor wholesaler four in food industries and three small retailers. For data analysis, we used the technical characteristics of the critical incident, content analysis and triangulation. The survey results identified the elements of the marketing strategy and relationship issues primarily from the perspective of distributor wholesaler. It has been found empirically that targeting influences the trust; the element influencing product partnerships and satisfaction; price element affects power / dependence, conflict, cooperation and satisfaction; element of marketing communication relates to investment, exchange of information and commitment; element distribution influences the conflict, among other relations. Ultimately, this study presents an analysis of the gaps / shortcomings as they relate to the elements of the marketing strategy developed by the wholesale distributor or the aspects of the relationship with food and small retail industry. Finally, we present the implications both managerial and theoretical, limitations and future research suggestions.

The literature has shown evidence that bullying is a worldwide phenomenon that deserves the attention of researchers and the community as a whole. Considering that bullying occurs in interpersonal relationships among students, it is important to understand the role of social skills repertoire of these individuals and their social competence to deal with the bullying situation, as a way to provide a more accurate diagnosis on the relationship of social skills and bullying, as well as contribute for the prevention of this type of violence. Considering these aspects, this study aimed to: (1) correlate social skills classes with authoring and victimization bullying behaviors; (2) compare the social skills of victims, authors, victims-authors and bystanders of bullying in terms of frequency and difficulty; (3) identify similarities and differences between the scores of authorship and victimization in bullying considering the self-assessment, peers and teachers evaluations; (4) assess and describe social competence indicators of teenagers involved in bullying; (5) functionally analyze the behavior of victims, perpetrators and bystanders of bullying. To analyze the social skills of students involved in bullying were applied the IHSA-Del-Prette, QIPVE and Peer Assessment with 241 adolescents aged 11 to 16 years. The data were analyzed descriptively and inferentially, and it was found that bullying behaviors and victimization showed a negative correlation with social skills classes. It was also found that students involved in bullying reported a less elaborate repertoire of self-control, assertiveness and empathy. Additionally, a comparison was also made between the bullying instruments used in this study. For this purpose 263 students responded to QIPVE and Peer Assessment, and 10 teachers appointed students as victims and bullies. This comparison brought data that there are differences between the self-assessment, evaluation of teachers and peers nominations about the involvement in bullying. To assess social competence indicators was realized an interview with 10 bullies, eight victims, 10 victims-authors and 10 bystanders. The interviews were transcribed and the responses were categorized. The results indicated that all respondents reported fail to achieve important indicators of social competence, which brings an impact on quality of life and development of these adolescents. Finally, the functional analysis of the student´s behavior pointed out that the attacks made by the bullies are reinforced by the removal of the victims and the bystanders’ silence and/or laughter. These datas indicate that anti-bullying programs should teach some specific social skills classes, promote not only social skills but also social competence and reach the entire school community, including bystander.

En una sociedad regida por una ideología oficial tejida por ideologías excluyentes y respaldadas por la constitución de la identidad global en detrimento de la alteridad, este trabajo se propone estudiar, a través de un análisis discursivo, la constitución de los sujetos ético-estético presentes en el funk y el rap nacional, entendidos como un movimiento contemporáneo de cultura popular urbano, la búsqueda para que sus voces sean escuchadas fuera de sus horizontes sociales. En principio, el sujeto estético presente en esas manifestaciones culturales, al buscar que sus voces sean escuchadas y visibles también fuera de su espacio de actuación, promueve la desestabilización de algunos hilos que constituyen la ideología hegemónica, al mismo tiempo que saluda nuevas formas de interacción social, y así, para la constitución de una sociedad basada en la alteridad. Es importante resaltar que ese este estudio no se enfocó en nombres o grupos específicos de funk o rap, y si en la búsqueda por discursos oriundos de esos movimientos culturales y también en discursos sobre los mismos que ratifiquen o no el objetivo propuesto. Este trabajo fue construido con el respaldo teórico de los estudios realizados por el Circulo de Bakhtin, principalmente los que recaen sobre los conceptos de sujeto, dialogía, carnavalización, así como los estudios de Bakhtin sobre cultura popular y fiesta. En general, se dialogó con Callois, Zumthor, Certau, Hall, Canclini, Martín-Barbero entre otros, con la finalidad de verificar la manera por la cual las voces de esos sujetos son valorizadas dentro y fuera de los barrios pobres por medio del embate ideológico ocurrido en y por la palabra ambivalente.

In this Thesis we expose the proposition of a new class of probability distributions, the so called alpha skew normal multivariate, an extension of the univariate Normal Alpha distribution, introduced by Elal-Olivero (2010). It can accommodates up to two modes and generalizes the distribution proposed by Elal-Olivero in its marginal components. In addition, we apply this new distribution in the construction of two new data mining methods for classi cation. The procedures developed here increment the predictive ability of the classi cation in the presence of asymmetric and / or bimodal data. The results indicate that the new proposal is signi cantly more appropriate than the usual modeling by classical normal distribution, and is also suitable for datasets without the presence of asymmetry. In this thesis it is shown, using real and synthetic data, the procedures of construction, estimation and validation for the new probability distribution and for probabilistic networks for binary classi cations, particularly for the k-dependence probabilistic networks.

This research aims to study the films that form the Elements Trilogy, by the Indo-Canadian director Deepa Mehta. Released between 1996 and 2005, the trilogy is part of the production by the Indian diaspora, that is to say, films without strictly defined national borders. Recurring themes in transnational films will be addressed, such as class, ethnicity, sexuality and the concept behind nations. Our purpose is to understand the power structures in India and its implications on female gender policies in these films. The trilogy comprises Fire (1996), 1947-Earth (1998) and Water (2005) and approaches three moments in Indian history throughout the female subjectivity. Deepa Mehta proposes discussions through the criticism presented in her films regarding the interconnection between the fundamentalism Hinduism and women's role in Indian society and culture. We intend to detect these criticisms as we analyze sequences in the three films, using the following method: observation of the narrative pattern, the themes chosen and the articulation of visual and sound strategies.

Current international and national politics about Special Education and Inclusive Education aims to ensure that all, without exception, have equal rights to access, permanency and opportunities for satisfactory learning in all segments and areas of knowledge proposed by the Basic Education, among them, Physical Education. Based on the premise that teacher vocational training collaborates with the conjectures of the inclusive movement, this study aimed to analyze whether and how a Continuing Education Program for Physical Education teachers contributes to the construction and reconstruction of knowledge about school inclusion, enabling (more) inclusive speeches and practices, especially for students with disabilities. To meet these objectives, the research presented here was characterized as qualitative, outlined by the action research insights and data analyzed by categories. The Continuing Education Program was attended five physical education teachers and the results showed that the activities developed and built at each meeting through dialogue (search), made possible the construction and the collective reconstruction of knowledge about inclusion in the program and beyond (action); especially because the participants were able to analyze, reflect and position on what they could and should do as those who believe in inclusion, seek knowledge and enable theories and inclusive practices. Consequently, the proposed and discussed knowledge in the Continuing Education Program (search) had significant contributions to the daily action/s participants. However, this research has reinforced the responsibility of the applicability of Inclusive Education assumptions should not only be the physical education teachers or teachers of any curriculum component of basic education; since the idea of inclusion is linked to multiple government, physical, curricular and attitudinal dimensions. In this vein, this research shows that access, permanence and learning opportunities for school education of all students, will only be possible if government agencies, school administrators, teachers, families, students and community do each of you, thus enabling , a society and a truly inclusive education for all, regardless of the specifics of this "all".

Brazil by presenting incomparable biodiversity, distributed in mosaic wonderfully distinct biomes becomes a promising the field of study in seeks of new phytochemicals extracted from native plants with biological activity on weeds and insects of medical importance. Species of Lauraceae and Dilleniaceae family have an immense potential in the production of secondary compounds with herbicide and insecticide properties. Thus, this study objective was to clarify the following questions: leaf extracts the stem and root Ocotea pulchella and Davilla elliptica could interfere with the growth and development of Triticum aestivum, Euphorbia heterophylla and Panicum maximum and thus make a new alternative for the control of weeds? Amongst the donor species and crude extracts which more promising to start a bioprospecting, allowing isolate and identify the present compounds? The extracts show insecticidal activity against eggs and larvae of Aedes aegypti? Coleoptile bioassays were performed using hexane extracts, dichloromethanic, acetoetilicos, methanolic and aqueous leaf, stem and root of O. pulchella and D. elliptica 0.2, 0.5 and 0.8 mg.mL-1. Most active extracts have been evaluated on the germination and early seedling growth of E. heterophylla and P.maximum using doses of 0.25, 0.5, 1 and 2 mg.mL-1. The larvicidal activity was evaluated at concentrations of 0.25, 0.5, 1, 2 and 3 mg.mL-1 and ovicidal effect with the LC50 and LC90 lethal concentrations estimated in test A. aegypti larvae. The leaf extracts O. pulchella inhibit coleoptile growth of wheat and seed germination and seedling growth of weeds and standard species. In general, the ethyl acetate extract O. pulchella showed higher phytotoxic activity. Eleven compounds were isolated and characterized. Compounds 1, 2, 4 and 6 have not been identified before in O. pulchella and Ocoteol was first described in the literature. The compounds 5, 10 and 11 were most active with superior inhibition values of 90% in the standard species. P. maximum has been the target species most affected by O. pulchella and D.elliptica leaf extracts in all evaluated parameters. The reduction in root growth of wild poinsettia seedlings can be related to the decrease in the elongation of metaxylem cells submitted at the ethyl acetate extract (O. pulchella) and methanol (D.elliptica). The extracts from root hexane and dichloromethane O. pulchella at a concentration 3 mg.mL-1 have produced bigger effect larvicide. Lower values of CL50 and CL90 were estimated for larvae subjected to the root extract from O. pulchella dichloromethane. Hatching rate, TME and VME have been affected by DCM and hexane root extracts from O. pulchella. Specie O. pulchella showed higher potential herbicide on the germination and the growth pattern and weed species and insecticide on larvae and eggs of A. aegypti.

The present work focuses on a research with samba composers memories who participated in the "Puxando Conversa" Project that, 1990 a 2004, was recorded in video and exhibited in public places, aspects of life and work of 49 samba composers in Rio de January State. Starting with reports, sung and narrated, in video programs, I try to understand the history of samba which is revealed, for the purpose of discussing dialogical relations that constitute the samba as popular culture. There are dialogues that are more controversial, as in the case of which is established between the tradition and the cultural industry, they are responsible for any transformations in which the samba has passed since its popularization in the media, but, in general, I analyze, in the composers statements, their representations about samba, raising the discourses as , investigating how such voices (re) construct ideologically and culturally the social body that circumscribe and still deconstruct and challenge an official model of culture and music. Therefore, I seek, firstly, issues involving the samba from its popularity, in the mid-1920, understanding all of social, historical and cultural context which allows the samba being an icon in our culture. And a study, at last, that involves questions of life and art. To better understand this plot, I refer to Mikhail Bakhtin studies about popular culture, especially those which I may understand the popular culture as the place where processes dialogues and processes clashes live in parity.

The research aims to think over about the overlaps between fiction and documentary in the film The Motorcycle Diaries (2004) by Walter Salles, using intermediality as method. We will use the intermedial phenomena proposed by Rajewsky (2012) as methodologi cal tools, thinking about intermedial transposition, combination of media and intermedial references. So, it's possible think over what kind of reading instruction is been triggered by the film, from the perspective proposed by Odin (2012): fictivizante or documentarizante. Our interest here is to think how literature transposed into film triggers such statements, relating the use of an open script to the reality of filming and also considering the influences between fiction and documentary related to road movie. We also seek to understand instructions that the film gives to emulate the photo and refer to documentary photography in three black and white sequences and using archival footage in the end credits.
