Biological invasion is considered a major threat to biological diversity. One of the consequences of converting forest to fragmented landscape is the entrance of exotic species into the interior of the forest remnants. Coffea arabica L. (Rubiaceae), the coffee plant, a native shrub species of African forests and historically introduced in Brazil for commercial purposes. Currently, the plant community is composed of many fragments of forest that bordered the old farms producing coffee with pronounced dominance. The study was conducted in a fragment of semideciduous forest in São Carlos, São Paulo. This study sought to generate information about the process or stage of the life cycle that influence population growth, investigating over two consecutive years the influence of removal of C. arabica on the growth of regenerating individuals of tree and shrub species , featuring floristic and structure of regenerating community where the presence of exotic species occurs. Data were collected in two areas of the fragment (edge and inside). Evaluation of population growth rate (λ) showed that the population remains stable in different environmental conditions, noting that the species is effectively established in the fragment, characterized as invasive species in this environment. It has not been possible to conclude that coffee influences the growth and/or establishment of natural regenerating community. The diversity and abundance differ between edge and interior of the fragment, with the greatest wealth in the forest interior. Note that this is one of the last remnants of Semideciduous Forest in the region of São Carlos, and despite its small size, isolation, impoverishment and the abundant presence of coffee, especially in its edge, knowledge about the composition and this operating environment is of utmost importance.

The novel Orphans of Eldorado (2008 ), by Milton Hatoum, brings into his narrative a number of references to Amazonian texts of different indigenous and riverine populations of the region of Manaus , Amazonia . Highlighting the indigenous elements , seems to build a deep dialogue with the call Amerindian literature , thus expanding the possibilities for analysis and interpretation of the work . The narrative is inspired by the myth of Eldorado , a possibly indigenous source of a series of records made throughout history that show the tense relationship between the colonial and post- colonial explorers in the Amazonian indigenous peoples and their lands . In addition to this story , other indigenous texts are cited and appear in the novel , composing a rich and heterogeneous scenario . To take account of this literary phenomenon , we mobilize our work in the categories of literary heterogeneity , intertextuality and rhizome , looking to make a broad approach that seeks to bring to the discussion the relevance of Amerindian substrate of the work , and show the importance of indigenous literature for this novel . We also consider it important to use the methodology of tensive semiotics to highlight gradations , the gradiência , and relationships , realizing the game of presence and absence of these indigenous elements that appear in the figures of sound, noise and silence. We believe that this work can contribute not only to compose the critical fortune of this novel , but to emphasize the importance of indigenous elements and indigenous reality in Brazilian literature and society.

The determinants of species distribution are continually questioned by researchers. What we know is that depending on the scale of approach such patterns may respond with different magnitudes. We did three approaches with different experimental designs with a common understory plant specie in central Amazonia. In the first chapter, we tested for the density-dependece on growth and mortality of seedlings. The results indicate that seedlings can grow less when alone in the natural environment, however, not observed experimentally. The second chapter, we describe the effects of neighborhood in reproductive effort. The reproductive frequency and intensity proved inconsistent spatially and temporally, the light was best explained the variation between neighborhood effects. And finally we explore the explanatory factors on Heliconia acuminata L. C. Richard (Heliconiaceae), distribution in mesoscale and landscape scale. The mechanims approach on a landscape scale becomes less representative by soil components distribution associated with altimetry in landscape set distribution patterns. The seedling emergence spatial pattern overlaps with the density in breeding and reproductive individuals, increase in occupancy around these individuals, independent of sample scale. In this scenario, we analized the density-dependence effects, neighbor effects and explanatory factors on H. acuminata in the three following chapter.

After identifying the interference of systemic mechanisms in education, reduced, in turn, to the utilitarian condition of simple means for the achievement of extrinsic ends, the dissertation presents the communicative praxis as a proposal of reflection and demarcation of the interests existing between system and culture. For this, it is taken into account the theoretical framework of Habermas, which guided by the paradigm of intersubjectivity, seeks to reintegrate a modern rationality and linguistically decentered (post-metaphysical), situated in the reality of procedural mode and based on the aspect dialogic performative of the interactions arising from the lived world. The communicative praxis, therefore, enables the enhancement of basic elements for democratic debate aiming the understanding , and then preventing the instrumental character of the unilateral coercions present in teaching procedures and, thus, to ensure learning that aims not only the logic of success, but also the experience of interactions permeated by cognitive, normative and aesthetic practices.

Child sexual abuse, according to the World Health Organization, has become a matter of public health, requiring interventions in the different spheres of society. Although alarming information, there are still few reports of this type of crime, which is permeated by secrets, shame and guilt. A victim of child sexual abuse often presents difficulties in discriminating the difference between what is a manifestation of affection and an abusive act thus can not act against these situations. To assist in this task, a strategy of prevention of child sexual abuse programs is the use of books Preventive Approach (LIAP), whose task autoprotetivas teach skills to children. In order to understand how this type of literature can help children to protect themselves from sexual abuse, three studies were conducted. The first is a systematic review of scientific literature on studies examining such LIAPs through pre-established criteria. The second study evaluated LIAPs Brazilian authors on child sexual abuse through criteria established by the literature in order to identify the potential within them to prevent child sexual abuse. The third is an empirical study and the central theme of the dissertation evaluated the effectiveness of storytelling as a means to acquire skills of self-protection against sexual abuse in children 2 years of elementary school and specifically, sought to check whether the reading of story of a book specially designed for the prevention of child sexual abuse, can promote substantially, acquiring skills of self-protection against child sexual abuse, compared to other children's book to prevent non-specific to child sexual abuse or a group that did not participate in any kind of reading. As a result, it was observed that children who participated in the interventions with the specific book about sexual abuse had higher overall performance compared to the performance of children from other groups.

In 1939, Carmen Miranda was a consecrated singer in Brazil, in her career on the radio broadcasting as well as theatres and casinos. As a national idol she went to the United States under a contract for a revue on Broadway. Her new career in the United States was seen by Brazilians as a diplomatic mission and she was required to represent her nation and introduce the national rhythm samba to the North-American audiences. At that time, she performed the national identity which was remodeled through the mass culture national dynamics, integrating popular and afro-Brazilian elements, but also filtering them in order to produce an image based on whiteness. In this way, the white artist, remembered for her remarkable green eyes and attuned to the Hollywoodian fashion, featured the Baiana character, a Brazilian national type which referred to a black woman. In her international career, however, she became the new representation of Latin America in the midst of the Good Neighbor Policy period. Carrying her stylized Baianas dressings, Miranda evoked a happy, cheerful, sensual, exuberantly representation of Latin America, offering the opportunity to escapism during the World War II. From the radio broadcasting to the Hollywood cinema, and also participating in some TV shows, Carmen Miranda was part of a process in which the Brazilian national identity came to be produced through the mass culture involving national and international creations. Through the concept of performativity, this thesis explores how Carmen Miranda created new symbolical senses about the national identity and Latin American representations in a form of complicity, with consolidated meanings based on coloniality , considering both national and international dimensions. Because of her path (closely related to the Brazilian popular culture), Carmen reproduced the cultural meanings involved in her representations through three constitutive elements: humor, exaggeration and caricature. These characteristics, alongside with self-parody and irony, enabled some kinds of audiences to read her performances as subversive in a sense that she was destabilizing the comprehension of identity as essence, and, at the same time, challenging social constructed hierarchies. These features allowed her to be appropriated as a camp icon, in the United States, and in a carnivalesque way, in Brazil.

This study aims to contribute to the anthropological debates regarding the notions of childhood and child in the scope of urban anthropology and anthropology of children. Through ethnography with children in two different social contexts - the Gonzaga favela (São Carlos-SP) and the Jardim Paulista condominium (Araras - SP) - I analyze the particularities and the plurality of the ways of being a child through the experiences and life of these agents in such urban spaces. The goal is to speculate on the multiplicity of possible childhood notions, paying attention to the ways in which such notions are linked to different definitions of families, house, street, risks and possible agencies.

This work is concerned with the orbital stability of special solutions called "standing waves" for Hamiltonian systems in a real and invariant Hilbert space under the action of a specific group of isometries in such space. The stability investigated is orbital in the usual sense for a dynamical system and is with respect to perturbations of the initial condition. Initially we approach the problem in an abstract manner and then we show an application of the discussed method.

This work is divided into two parts. In the first part, our goal is to present the theory of Hardy Spaces Hp(Rn), which coincides with the Lebesgue space Lp(Rn) for p > 1, is strictly contained in Lp(Rn) if p = 1, and is a space of distributions when 0 < p < 1. When 0 < p ^ 1, the Hardy spaces offers a better treatment involving harmonic analysis than the Lp spaces. Among other results, we prove the maximal characterization theorem of Hp, which gives equivalent definitions of Hp, based on different maximal functions. We will proof the atomic decom¬position theorem for Hp, which allow decompose any distribution in Hp to be written as a sum of Hp-atoms (measurable functions that satisfy certain properties). In this step, we use the strongly the of Whitney decomposition and generalized Calderon-Zygmund decomposition. In the second part, as a application, we will prove that nonlinear quantities (such as the Jacobian, divergent and rotational defined in Rn) identied by the compensated compactness theory belong, under natural conditions, the Hardy spaces. To this end, in addition to the results seen in the first part, will use the results as Sobolev immersions theorems ans the inequality Sobolev-Poincare. Furthermore, we will use the tings and results related to the context of differential forms.

Complex data, like images, face semantic problems in your queries that might compromise results quality. Such problems have their source on the differences found between the semantic interpretation of the data and its low level machine language. In this representation are utilized feature vectors that describe intrinsic characteristics (like color, shape and texture) into qualifying attributes. Analyzing the similarity in complex data, perceives that these intrinsic characteristics complemented the representation of data, as well as is carried out by human perception and for this reason the use of multiple descriptors tend to improve the ability of discrimination data. In this context, another relevant fact is that in a data set, some subsets may present essential specific intrinsic characteristics to better show their rest of the data elements. Based in such premises, this work proposes the use of boundary conditions to identify these subsets and then use the best descriptor combination balancing for each of these, aiming to decrease the existing semantic gap in similarity queries. Throughout the conducted experiments the use of the proposed technique had better results when compared to use individual descriptor using the same boundary conditions and also using descriptors combination for the whole set without the use of boundary conditions.

Although the relationship between psychoanalysis and biology has been denied by many Freudian followers, today much study has been done in Freud's work, resuming his concepts within the naturalistic bias. Aiming to deepen these relationships, this study aims to analyze the convergences between the psychoanalytic concept of object choice and sociobiological studies regarding choice of partners. For psychoanalysis, human sexuality doesn´t have a main objective to reproduce, but this does not take us away from biological conceptions of sexuality, as is pointed out by several theoretical biology and contrary to a widespread view within the psychoanalytic means. It is thus to analyze how psychoanalysis and biology study this aspect of human sexual behavior, including their specificities, but also looking to evaluate their degree of convergence and complementarity that can then establish

A reduction in social contact among the elderly can result in unhealthy social isolation, and an increase in depressive symptoms. To combat this problem, services for the elderly are emerging, but little is yet known about the factors that affect the use of these services and the contribution of these programs to reduce social isolation. On the basis of the literature review, a new instrument was constructed to evaluate the extent to which older people who are engaged in activities outside the family circle feel that these involvements create opportunities to be more active, more competent, meet new people, form new friendships, learn new skills, do something they enjoy, or to do something related to their personal interests. The overall objectives of the current study were to: a) compare the perceptions of users and non-users of services for the elderly, with respect to their perceptions of the adequacy of their opportunities for social contact outside the family, and b) to determine if elderly people with more positive perceptions of these activities also report fewer depressive symptoms. Participants included 60 people aged 65 years or older (15 female and 15 male service users, and 15 female and 15 male non-users), all residing in a small city with approximately 122.000 inhabitants, in the interior of the state of São Paulo, Brazil. All respondents obtained scores equal to or above their cut-off score on the Mini Mental State Examination, such that all participants presented normal cognitive functioning. After signing the consent form, the participants responded to instruments about their financial status, physical and mental health (Brazilian Socioeconomic Criteria, Katz Scale of ADL, the PAQ and the Geriatric Depression Scale). Next, participants rated the extent to which their nonfamily activities meet their needs for social inclusion. The two groups were highly similar with respect to socioeconomic status, education, and functionality levels. The main findings indicate that both users and non-users of services for the elderly reported a high level of satisfaction with their non-family activities. In addition, average ratings of their opportunities for social inclusion were high in both groups, but those who used services for senior citizens had fewer depressive symptoms than those who did not use these services, which is coherent with some other studies that point to the positive effects of attending universities for senior citizens. As such, the primary contribution of this study was to initiate more detailed work, to identify and better understand how to create opportunities for the social inclusion of the elderly.

The goal of this PhD thesis was to propose alternatives to improve the analytical performance of F AAS (Flame Atomic Absorption Spectrometry) and LIBS (Laser Induced Breakdown Spectroscopy) aiming V and Mo determination. Some analytical procedures, in agreement with the Green Chemistry principles of, as the cloud point extraction (CPE) and dispersive liquid-liquid microextraction (DLLME) were evaluated in different kind of samples (mineral water, medicines and soil). First was evaluated some parameters concerning to the CPE and the instrumental parameters, using factorial design in order to obtain the better conditions for the extraction of V and Mo individually and simultaneously, as well as the minimum sample volume necessary to introduce in the nebulizer. The limits of detection (LOD) achieved with the CPE to extract individual V and Mo were 80 and 20 μg L-1, respectively. When the CPE procedure was applied for simultaneous extraction, the LODs were 80 and 70 μg L -1 to V and Mo, respectively. The developed procedure was applied in two real samples of medicines and the recoveries obtained were 107 ± 4 % and 98 ± 2 % for V and Mo, respectively. Measurements in presence of Fe (II) (possible interfering) in proportions higher than 1:10 (V: Fe and Mo: Fe) were performed and the absorbance signals of V and Mo decrease thereabout 30 and 50%, respectively. In the second work a procedure employing dispersive liquid-liquid microextraction for the determination of V and Mo by LIBS was developed and applied in water, medicines and soil samples. Some factorial designs were also performed to optimize the best conditions for DLLME procedure. After the optimization, a sample volume of 10 μL was dried in a piece of aluminum foil and submitted to determination by LIBS. The combination of DLLME-LIBS is quite feasible since microextraction is fast, easy to apply, low-cost, they have the possibility of automation, generates little waste and the small volume of the final extract is sufficient for the LIBS analysis. The LOD achieved with the proposed method were 5 and 30 μg L-1 for V and Mo, respectively. The procedure was applied to real samples of two medicines, where the recoveries obtained by comparing with the standard addition method and determination by ICP OES ranged 92-104% for V and 96% for Mo. In the soil sample recovery was 97 ± 15% for V and Mo was below the LOQ and a reference material NCS ZC 85005 (Beef Liver) where V was below the LOQ and the recovery obtained for Mo was 102 ± 21%.

This study presents a pump scheduling problem for the capture, transfer and storage of water supply systems in urban networks, whose objective is to minimize the electricity cost associated to the pumping operations. To deal with the dynamic and random nature of the water-demand, we propose two-stage stochastic programming with recourse models, where the random variables are represented by a finite and discrete set of realizations or scenarios. The developed mathematical models are extensions of previous deterministic models of the literature and they reflect the basic assumption that a fixed cost could be incurred by the turn on/ turn off activities of the hydraulic pumps. In order to control violations of the water-demand constraints in the presence of multiple different scenarios, we also consider a robustness technique in an attempt to obtain almost feasible solutions. Last, but not least, we adopt a risk-aversion criteria so-called mean absolute deviation to obtain second-stage costs less dependent on the realizations of the scenarios. The scenarios were generated according to a Monte-Carlo simulation procedure that may use any probability distributions to produce the empirical probabilities of the random variables. As the proposed pump scheduling problem with fixed cost is a two-stage stochastic mixed 0 − 1 program, we develop a efficient hybrid heuristic to obtain good-quality solutions of practical instances in a plausible running time. Overall results evidence the stability of the scenario generation method, the sensitivity of the solution according to the key parameters of the mathematical model, and the efficiency of the heuristic in solving large instances. Finally, we show that is possible to save resources by solving the stochastic programming model instead of adopting simpler approaches based on the expected value.

The teaching-learning process of a foreign language for the Third Age is a theme that demands attention and has been little explored. Through the investigation of beliefs and motivational aspects in such a context, we intend to provide subsidies for the development of teachers competences, especially the ones who are involved with the referred public. By having in mind that this issue demands knowledge of the real changes that occur during the process of ageing, we have sought support in the fields of Gerontology, Sociology, Psychology and Applied Linguistics itself. The theoretical framework of this thesis was based upon Neri (1991, 1993, 1995, 2000), for the issues related to the Third Age; Dörnyei (1994, 2001, 2005), for the motivational aspects; Barcelos (2001, 2004), for the beliefs, and Almeida Filho (2002, 2005, 2012), for the competences. The research was developed through several instruments such as questionnaires, interviews and self-reports, which involved 110 participants. The analyzed data show us some aspects to be considered in the conduction of the teaching-learning process. We have to consider the single characteristics of the Third Age public, so that we can be aware of the benefits of a social and cognitively exciting environment for the development and maintenance of the elderly physical and mental capacities. However, to achieve this awareness, it is necessary to overcome some possible stereotyped and prejudiced ideas or images of the old people and the old age that are current in society, especially when it refers to the beliefs that old people are not able to acquire a foreign language, that while getting older, we start losing memory gradually and that the elderly do not feel motivated to the acquisition of knowledge or the acquisition of another language anymore.

Problematize the carnivalesque as a political inorganization a multitude of subjects who transgress power relations is the general aim of the thesis study. Popular demonstrations in societies that emerge are answers to the oppressor s mechanisms and relations of power that the capitalist logic promotes. These popular events appear as everyday ideology through carnivalesque relationships and are problematized, by this reflection, as objects of study. Two cutouts appear as places of observation in order to emphasize the clashes. 1) The street carnivals that reappear in the last ten years in the national and international scene as noted by the media dissemination. 2) The movement known as Carnival Against Capitalism - promoted by individuals from different countries constituting crowds that destabilize power relations. For such thinkers as Bakhtin (2006a, 2010a, 2010b, 2010c, 2011a ) and Negri, Hardt ( 2005a ) are crucial references in this architectural reflection. Some questions guide this study: 1) What can be read as manifestations carnival towards transgredient? 2) How different subjects do carnival? The purpose is specifically from such questions: 1) argue that every day events can carry a valued investment and such investment, disrupts discourses and relations of domination. 2) Affirm the existence of a "collective of a singularity which are not limited to the massive pocket of dough and composes the crowd. 3) Understand the crowd as a grotesque body - tireless and inalienable. Taking for granted the inextricable link between the social situation and the sign key understandings were: 1) There is no cohesive identity, but identities in constant struggle. 2) There is no speech that completely silenced the other, but lives in the discursive struggle linguistic materiality. 3) The carnivalization is a form of activism, a responsive activity. 4) A rule carnival happens as a counterpoint to the official system through various demonstrations and protests, art, music and parties. 5 - A crowd of singularities also has an affirmative view towards transgredient. Their actions may be carnival i.e., responses to ethics rectified. The research methodology is based on the theoretical perspective of Bakhtin's dialogical dialectic - clash of words and against words - which briefly means that the sign is part of a communication system and therefore cannot be separated from the concrete forms of communication, there is no separation between material reality and ideology of the sign, and there is a tense relationship between official and everyday discourses of.

In this work, we consider the estimation of the number of errors in a software from a closed population. The process of estimating the population size is based on the capture-recapture method which consists of examining the software, in parallel, by a number of reviewers. The probabilistic model adopted accommodates situations in which reviewers are independent and homogeneous (equally efficient), and each error is an element that is part of a disjoint partition in relation to its detection probability. We propose an iterative process to obtain maximum likelihood estimates in which the EM algorithm is used to the nuisance parameters estimation. The estimates of population parameters were also obtained under the Bayesian approach, in which Monte Carlo on Markov Chains (MCMC) simulations through Gibbs sampling algorithm with insertion of latent variables were used on the conditional posterior distributions. The two approaches were applied to simulated data and in two real data sets from the literature.
