Dwellers of agrarian reform settlements have a life conditioned by poor living and work conditions, difficulties accessing health programs, social assistance and other public policies and by this exacerbating their psychosocial and environmental vulnerability, which has an impact on their mental health. This research investigates the availability of support by the health and social assistance staff, regarding the demands of common mental disorders and alcohol abuse of dwellers of nine settlements in Rio Grande do Norte. Fifty three experts from different professional categories were interviewed individually or in groups. The results indicate that the workers suffer from poor working conditions, attributes of patrimonial heritage and welfare, which still survives in Brazilian social policies and particularly at local administrations of the countryside. The staffs have little knowledge of the local conditions and of the mental health needs, which has a negative impact on the reception and offered care. The implemented health care still corresponds to the biomedical logic, characterized by ethnocentrism, technicality, biology, cure, individualism and specialization, with little participation of the dwellers and disregarding the traditional knowledge and practices of local health care and by this not achieving the expected results. The psychosocial attendance is not well coordinated, presenting problems with the follow-up and continuity of care. The psychosocial mental health care in rural context has to face the challenge of the reorganization of the health care networks, the establishment of primary health care close to the people’s everyday life, building intersectional practices considering a health multidetermination and health education connected to these specific contexts. Due to the lack of knowledge of the specifics of the life conditions of the dwellers and the fragmentation of the psychosocial health care network, these staffs do not abide and are not ready to face the mental health needs in order to interfere with these health iniquities.

The Atlantic Forest in Rio Grande do Norte (RN) is included in Pernambuco biogeographic sub-region and it is composed by Semi-deciduous Forest, deciduous Forest, Mangrove and Restinga. We assessed the conservation status of Atlantic Forest in the RN through remnants mapping using high resolution satellite images and landscape ecology approaches. We evaluated if there is difference between the north and south coastal regions considering their natural a historical land use differences. We also assessed the influence of the small remnants on landscape cover and configuration. The proportion of the original biome area with remnants larger than 3 hectares is 15.60% for the official governmental limit and is 16.60% for the alternative limit (SNE, 2002). This remnants proportion varies between 0.56 and 46.52% in the hydrographic basins. 89.70% of the remnants are smaller than 50 hectares. Only 6.00% of the remnants are greater than 100 hectares, and these remnants are responsible by 65% of remaining area. The patches with smaller area influence all calculated metrics. The south coastal hydrographic basins have higher percentage of coverage of remnants, larger patch densities and fragments with larger areas than north coastal hydrographic basins. The diffuse drainage basins of the southern coastal have the highest percentage of coverage with remnants. 18.28% and 10% of the biome area are protected by reserves, according to the official governmental and alternative limits respectively. The reserves are mainly of sustainable use (IUCN V-VI). Therefore, the Atlantic Forest in Rio Grande do Norte is in critical situation, with low proportion of remaining area and high fragmentation level. It’s indispensable to biome conservation keep all the remaining area, especially the large remnants, and restore areas to increase remnants proportion and to increase landscape connectivity

Psychology is a relatively new scientific branch and still lacks consistent methodological foundation to support its investigations. Given its immaturity, this science finds difficulties to delimit its ontological status, which spawnes several epistemological and methodological misconceptions. Given this, Psychology failed to demarcate precisely its object of study, leading, thus, the emergence of numerous conceptions about the psychic, which resulted in the fragmentation of this science. In its constitution, psychological science inherited a complex philosophical problem: the mind-body issue. Therefore, to define their status, Psychology must still face this problem, seeking to elucidate what is the mind, the body and how they relate. In light of the importance of this issue to a strict demarcation of psychological object, it was sought in this research, to investigate the mind-body problem in the Phenomenological Psychology of Edith Stein (1891-1942), phenomenologist philosopher who undertook efforts for a foundation of Psychology. For that, the discussion was subsidized from the contributions of the Philosophy of Mind and the support of the phenomenological method to the mind-body problem. From there, by a qualitative bibliographical methodology, it sought to examine the problem of research through the analysis of some philosophical-psychological philosopher's works, named: "Psychic Causality” (Kausalität Psychische, 1922) and “Introduction to Philosophy" (Einführung in die Philosophie, 1920). For this investigation, it was made, without prejudice to the discussion, a terminological equivalence between the terms mind and psyche, as the philosopher used the latter to refer to the object of Psychology. It sought to examine, therefore, how Stein conceived the psyche, the body and the relationship between them. Although it wasn't the focus of the investigation, it also took into account the spiritual dimension, as the philosopher conceived the human person as consisting of three dimensions: body, psyche and spirit. Given this, Stein highlighted the causal mechanism of the psyche, which is based on the variations of the vital force that emerges from the vital sphere. In relation to the corporeal dimension, the philosopher, following the analysis of Edmund Husserl (1859-1938), highlighted the dual aspect of the body, because it is at the same time something material (Körper) and also a linving body (Leib). On the face of it, it is understood that the psyche and the body are closely connected, so that it constitutes a dual-unit which is manifested in the Leib. This understanding of the problem psyche-mind/body provides a rich analysis of this issue, enabling the overcoming of some inconsistencies of the monistic and dualistic positions. Given this, it allows a strict elucidation of the Psychology object, contributing to the foundation of this science.

This work aimed at analyzing the speeches constructed about motivation by English teachers who teach at public state schools in the interior of Minas Gerais. We aimed at delineating the concept of subject underlying the subjects’ notion of motivation and identifying the role that the English teacher attributes to himself and to the student when he/she enunciates on motivational issues, problematizing the possible consequences of these issues for some English teachers while working in public schools. In order to do so, our investigation made use of theoretical assumptions from Applied Linguistics and Discourse Analysis. The theoretical fundamentation deriving from Bakhtin Circle as well as from Michel Pecheux’s theoretical basis were also very relevant for this research. The intersection of these studying fields entails a theoretical construction that considers the voices of those who live the social practice (MOITA LOPES, 2006), which allows one to see the subjects through their heterogeneity, fluidity and fragmentation. Moreover, it generates knowledge about language in its political, ideological, social and historical aspects. AREDA (SERRANI, 1998) was used as a theoretical and methodological framework for data collection. In our analysis, we considered the voices and the conditions of production that constitute 5 English teachers and, from some selected speeches extracted from their discursive production, some notions as intra and interdiscourse, discursive resonance, discursive memory, among others, can be seen interwoven. We hypothesize that the production of meaning deriving from these English teachers comes from a cleavage between the interdiscursivity about motivation and their position in relation to the English language. Some of these teachers’ discursive inscriptions were delineated as they follow: i) the silenced motivation, in which the teachers come up with several voices, repeating what that has already been said about motivation through silence by excess; also, through an inscription in a process of anomy, the English teachers silence motivation, as they come up with other sayings, in an anomic order, denying their identification with their mother tongue and culture because of a desire to learn the foreign language and culture; ii) the motivation in/from/ by others that resounds, in the way the teachers speak, a relation of alterity on what, in/from desire of other relations (colleagues, students, teaching materials, media, etc.), other forms and alternatives are established as a guarantee of students’ motivation; the teachers are also inscripted in in-service practice training as a space of educational development, because they imagine that the experience of the in-service practice alone, which excludes the educational instruction from the Languages course in which they graduated/were graduating at, taught them how to motivate the students; iii) the motivation as a will of power/knowledge, which means there seems to be teachers’ inscription in the relationship between power and knowledge (Foucault, 1996), disconsidering the conflicts that constitute the English classroom to say that there is a control of the English teaching and learning process and, as a result, they also sustain that they hold control over how to motivate; furthermore, the presence of a resonant voice, whose effect is given by an inscription on the (illusion of) completeness can be seen, because the English teachers believe that while motivating their students, this motivation will provide them with all the missing elements, which would mean that when they motivate students, they would be able to fulfill all the gaps in their learning process.

Reconhecendo, a partir da constatação empírica, a multiplicidade de escolhas de crenças no Mundo e em particular na periferia urbana paulistana, reconhecemos, também, a emergência criativa de novas possibilidades de crer e não crer. Tal amplitude não apenas aponta para o crer (segundo as ofertas de um sem número de religiões) e o não crer (ateu e agnóstico), mas para uma escolha que poderia vir a ser silenciada e esquecida, neste binômio arcaico e obsoleto, quando alguém se dá à liberdade crer sem ter religião. Reconhecer interessadamente os sem-religião nas periferias urbanas paulistanas é dar-se conta das violências a que estes indivíduos estão submetidos: violência econômica, violência da cidadania (vulnerabilidade) e proveniente da armas (grupos x Estado). Tanto quanto a violência do esquecimento e silenciamento. A concomitância espaço-temporal dos sem-religião nas periferias, levou-nos buscar referências em teorias de secularização e de laicidade, e, a partir destas, traçar uma história do poder violento, cuja pretensão é a inelutabilidade, enquanto suas fissuras são abertas em espaços de resistências. A história da legitimação do poder que se quer único, soberano, de caráter universal, enquanto fragmenta a sociedade em indivíduos atomizados, fragilizando vínculos horizontais, e a dos surgimentos de resistências não violentas questionadoras da totalidade trágica, ao reconhecer a liberdade de ser com autonomia, enquanto se volta para a produção de partilha de bens comuns. Propomos reconhecer a igual liberdade de ser (expressa na crença da filiação divina) e de partilhar o bem comum em reconhecimentos mútuos (expressa pela ação social), uma expressão de resistência não violenta ao poder que requer a igual abdicação da liberdade pela via da fragmentação individualizante e submissão inquestionável à ordem totalizante. Os sem-religião nas periferias urbanas, nossos contemporâneos, partilhariam uma tal resistência, ao longo da história, com as melissas gregas, os profetas messiânicos hebreus, os hereges cristãos e os ateus modernos, cuja pretensão não é o poder, mas a partilha igual da liberdade e dos bens comuns. Estes laicos, de fato, seriam agentes de resistências de reconhecimento mútuos, em espaços de multiplicidade crescente, ao poder violento real na história.

This paper presents the theoretical-methodological possibilities of the French philosopher and sociologist Henri Lefebvre, for the discipline of architecture and urbanism in an effort to overcome the fragmentation imposed by the institutionalization of science in general. From Du rural à l'urbain (Lefebvre, 1970) compilation, it brings the author's other works from the period between 1968 and 1974, indicating the conduits for reflection and their interrelationships with methods, types of analyses and other procedures to treat the space-time urban. The methodology involves a research on the author s 'today and yesterday' in the scientific field, a research and analysis of his procedures in highlight of philosophical, social, economic and political aspects, the historical context of his references and provides significant and possible elements for the study, research and extension in the area in question

Habitat fragmentation and the consequently the loss of connectivity between populations can reduce the individuals interchange and gene flow, increasing the chances of inbreeding, and the increase the risk of local extinction. Landscape genetics is providing more and better tools to identify genetic barriers.. To our knowledge, no comparison of methods in terms of consistency has been made with observed data and species with low dispersal ability. The aim of this study is to examine the consistency of the results of five methods to detect barriers to gene flow in a Mediterranean pine vole population Microtus duodecimcostatus: F-statistics estimations, Non-Bayesian clustering, Bayesian clustering, Boundary detection and Simple/Partial Mantel tests. All methods were consistent in detecting the stream as a non-genetic barrier. However, no consistency in results among the methods were found regarding the role of the highway as a genetic barrier. Fst, Bayesian clustering assignment test and Partial Mantel test identifyed the highway as a filter to individual interchange. The Mantel tests were the most sensitive method. Boundary detection method (Monmonier’s Algorithm) and Non-Bayesian approaches did not detect any genetic differentiation of the pine vole due to the highway. Based on our findings we recommend that the genetic barrier detection in low dispersal ability populations should be analyzed with multiple methods such as Mantel tests, Bayesian clustering approaches because they show more sensibility in those scenarios and with boundary detection methods by having the aim of detect drastic changes in a variable of interest between the closest individuals. Although simulation studies highlight the weaknesses and the strengths of each method and the factors that promote some results, tests with real data are needed to increase the effectiveness of genetic barrier detection.

Com o presente trabalho pretende-se discutir a importância do DNA na resolução de casos de investigação forense. O Homem, desde os tempos mais remotos tem revelado interesse na confirmação da identidade dos seus semelhantes, pelo desenvolvimento e prática de diversas técnicas de identificação. A partir de uma revisão da literatura, fez-se o estudo dos métodos de identificação humana, sendo este mais aprofundado no que diz respeito ao DNA. Frequentemente são encontrados corpos em que a única peça disponível para o processo de identificação é o dente. As peças dentárias são as estruturas mais resistentes e estáveis do corpo humano, mantendo as suas características e propriedades por longos períodos de tempo pós-morte. A análise do DNA contribui de forma muito importante para os processos de reconhecimento humano, principalmente em casos em que outros métodos de identificação falham devido a decomposição, fragmentação, incineração ou inexistência de dados comparativos ante-morte. Para a obtenção de um perfil genético é necessário executar as seguintes etapas: extração do DNA, sua quantificação e amplificação seguida de análise de determinadas regiões do genoma. Nos dias de hoje, muitos casos de identificação necessitam de uma abordagem multidisciplinar, isto porque em algumas situações existe falta de material padrão ou, por outro lado, pode haver mais do que uma evidência a ser examinada.

The present work analyzes the fast evolution of gated communities in Natal-RN´s urban space. Characterized by the occupation of large areas, providing private security and utilities, this kind of real estate use arises a long list of questions and issues from society and scholars, due to privatization of urban space, bending of law constraints and the lack of an integrated planning of the cities where they are built. The reasons for its fast growth in Brazil s urban areas are analyzed, considering the impact on formal urban planning and municipal services and on the identification of urbanistic, architectural pattern and constraints, as well as legal, social and economic issues. This study is based on the detailed analysis of the first three units of gated communities built in the urban space in Natal, between 1995 and 2003, including their evolution throughout time and the specific social and economic reasons for its present widespread adoption in Brazilian real estate market and, particulary, in our city. The main objective of this piece of work is to answer the why s and how s these phenomena evolved, setting a basis for the definition of adequate public policies and regulation of this kind of urban land use

The transformations economical, social and politics in you finish them decades of the century XX brought changes that didn't just limit to the production system. The flexible accumulation took many workers lost her/it their workstations and they look for her/it new survival forms, migrating for administrative activities, of services rendered and for the tourist activity of small and medium load. The State has been investing in the implantation of plans of tourist development in order to create favorable conditions for the reproduction of the tourist activity in Brazil, mainly in the Northeast. A space when it starts to present a predominant economical activity suffers a restructuring in their social and economical relationships. The restructuring of these relationships takes to the construction of a new espacialidade. In the city of Christmas, in Rio Grande do Norte, the neighborhood of Black Tip is the most representative of the public investments for the tourist development. After intense process of tourist urbanization, Black Tip passed interfering in the global context consolidating as the tourist locus in the city. The tourist urbanization of the neighborhood took to the transformation of the space in merchandise that is sold and consumed as such. The recreation of fragments of other cultures brought by social actors, resulting from migratory processes stimulated by the tourist development, it has been presenting ruled social relationships in the informational technology, consumption of global goods and in the fragmentation of the urban space characterized by the internationalization and cosmopolitização. That process has been masking the inequalities partners and cultural as well as the territorial appropriation for an economical elite. The spaces are being appropriate for investors of the tourist section, private investors, agents and real estate producers, where the inequality is not just economical, but also cultural. The local population, mainly of the urban fraction of the Town of Black Tip, it doesn't participate of the productive process in function of the little or any professional qualification and he/she doesn't also have access to the consumption process. To the native ones it remains the fight for the preservation of his/her cultural identity and for the survival

Eventos climáticos extremos poderão ter conduzido à instabilidade de habitats e em última instância à sua fragmentação, causando repercussões ainda visíveis nos predadores de topo, tais como o boto (Phocoena phocoena). Consequentemente, os indivíduos que não se adaptaram, tiveram de procurar novos habitats com as respetivas condições ideais, nomeadamente os indivíduos da população de botos do Atlântico Este (norte e sul da Baía de Biscaia). O presente estudo focou-se em indivíduos da costa portuguesa (representando uma amostra da população residente a sul da Baía de Biscaia) e, recorrendo a informação proveniente de estudos previamente realizados, procurou salientar diferenças entre os botos que habitam ao longo do Atlântico Este. Foi aplicado um método de limpeza e branqueamento em crânios de boto, para posterior medição. Foram medidos 65 crânios de botos (programa Image J®), providenciados pela rede de arrojamentos de animais marinhos e obtidos no âmbito do projeto LIFE+ MarPro. As comparações das medidas dos crânios entre géneros foram realizadas a partir de modelos alométricos (programa GraphPad Prism ®) e as comparações entre géneros de cada estágio de desenvolvimento foram efetuadas com recurso a uma análise de PERMANOVA unifatorial (usando distâncias euclidianas), através do programa PAST® v. 2.12. Concluiu-se que na população em estudo, tanto as fêmeas como os machos apresentaram um modelo de alometria negativa. Reportou-se que as fêmeas apresentam comprimentos corporais superiores aos machos, assim como comprimentos e larguras cranianas. Comparativamente aos indivíduos da população a norte da Baía de Biscaia, a amostra de estudo da população do sul da Baía de Biscaia (representada pelos indivíduos da costa portuguesa) apresentou maiores comprimentos corporais e cranianos e maior largura craniana. Estes resultados corroboram observações prévias sobre a população de botos do Atlântico, que detetaram já diferenças genéticas e partilha limitada de genes, diferenças nos hábitos alimentares e habitats distintos nos botos de norte e sul da Baía de Biscaia.

During the last years tropical forest has been a target of intense study especially due to its recent big scale destruction. Although a lot still needs to be explored, we start realizing how negative can the impact of our actions be for the ecosystem. Subsequently, the living community have been developing strategies to overcome this problem avoiding bottlenecks or even extinctions. Cooperative breeding (CB) has been recently pointed out as one of those strategies. CB is a breeding system where more than two individuals raise one brood. In most of the cases, extra individuals are offspring that delay their dispersal and independent breeding what allows them to help their parents raising their siblings in the subsequent breeding season. Such behavior is believed to be due, per example, to the lack of mates or breeding territories (ecological constraints hypothesis), a consequence of habitat fragmentation and/or disturbance. From this point, CB is easily promoted by a higher reproductive success of group vs pairs or single individuals. Accordingly, during this thesis I explore the early post-fledging survival of a cooperative breeding passerine, namely the impact of individual/habitat quality in its survival probability during the dependence period of the chicks. Our study species is the Cabanis’s greenbul (Phyllastrephus cabanisi), a medium-sized, brownish passerine, classified within the Pycnonotidae family. It is found over part of Central Africa in countries such as Angola, Democratic Republic of the Congo, Mozambique and Kenya, inhabiting primary and secondary forests, as well as woodland of various types up to 2700m of altitude. Previous studies have concluded that PC is a facultative cooperative breeder. This study was conducted in Taita Hills (TH) at the Eastern Arc Mountains (EAM), a chain of mountains running from Southeast Kenya to the South of Tanzania. TH comprises an area of 430 ha and has been suffering intense deforestation reflecting 98% forest reduction over the last 200 years. Nowadays its forest is divided in fragments and our study was based in 5of those fragments. We access the post-fledging survival through radio-telemetry. The juvenile survey was done through the breeding females in which transmitters were placed with a leg-loop technique. Ptilochronology is consider to be the study of feather growth bars and has been used to study the nutritional state of a bird. This technique considers that the feather growth rate is positively proportional to the individual capability of ingesting food and to the food availability. This technique is therefore used to infer for individual/habitat quality. Survival was lowest during the first 5 days post-fledging representing 53.3%. During the next 15 days, risk of predation decreased with only 14.3% more deceased individuals. This represents a total of only 33% survived individuals in the end of the 50 days. Our results showed yet a significant positive relationship between flock size and post-fledging survival as well as between ptilochronology values and post-fledgling survival. In practice, these imply that on this population, as bigger the flock, as greater the post fledging survival and that good habitat quality or good BF quality, will lead to a higher juvenile survival rate. We believe that CB is therefore an adaptive behaviour to the lack of mates/breeding territory originated from the mass forest destruction and disturbance. Such results confirms the critical importance of habitat quality in the post-fledging survival and, for the first time, demonstrates how flock size influences the living probability of the juveniles and therefore how it impacts the (local) population dynamics of this species. In my opinion, future research should be focus in disentangle individual and habitat quality from each other and verify which relationship exist between them. Such study will allow us to understand which factor has a stronger influence in the post-fledging survival and therefore redirect our studies in that direction. In order to confirm the negative impact of human disturbance and forest fragmentation, it would be of major relevance to compare the reproductive strategies and reproductive success of populations living in intact forests and disturbed patches.

Brazil is home to one of the richest avifaunas the world, which is subject to high levels of environmental degradation, in particular forest fragmentation. The Atlantic Forest biome depicts this history of devastation and today remains as small isolated fragments on highly degraded landscapes. This project aimed to evaluate the effects of forest fragmentation in an area with Atlantic Forest remnants in northern Paraná (Brazil) on the distribution and the organization of assemblage of forest birds and tested the hypothesis that the structure of the assembly in the fragments is different than expected by chance. We did four qualitative samplings of birds in three sets of forest fragments in the landscape, each with three fragments: large, medium and small. The method applied in the sampling was point counts along transects, traveled randomly for four hours in each fragment. Samples were taken in two periods: from September to November / 2013, and between March and May / 2014. The structure of the meeting was assessed by rates of co-occurring species (Checkerboard and CScore) and α diversity patterns (wealth) and β (turnover of species), while the landscape structure was analyzed from the parameters: area, distance between fragments, fractal dimension, edge density, fragment shape index and nuclear area index. The null hypothesis of no structure in the assembly of birds in the landscape was tested with null models from the co-occurrence indexes. The effects of landscape structure on the assembly of the structure were analyzed by the Mantel test and principal component analysis (PCA). The assembly of the structure in the landscape showed a pattern of spatiotemporal organization significantly different from that expected by chance, revealing a structure most influenced by segregation of the species. The fragments showed significant differences in richness, unlike sets of fragments, indicating relative homogeneity in the landscape structure. The differences between the size and the distance between the fragments significantly influenced the patterns of organization of the meeting of forest birds in the landscape and patterns of α and β diversity, indicating that the higher the fragment and smaller distances between them, more the standard of species cooccurrence is different than expected by chance. Thus, the fragmented landscape of remnants of the northern Paraná Atlantic Forest still has availability of environmental resources and physical characteristics that allow a persistent organizational structure of the assembly of forest birds in space over time.

Currently, the biodiversity is considered as a powerful food security strategy, ecological and economical for humanity. Brazil is one of the main centers of genetic diversity of native fruit in the world. However, little is known about most of these species. In southwestern Paraná region, this diversity can be found, however, due to human action to increase genetic erosion, it is losing genotypes with potential for use. Thus, the conservation of genetic resources is essential for reduction strategies for damage caused to the environment and the lack of tech-nical information to increase the use of them. This study aimed to obtain information for cre-ating on farm net conservation in four citties this region. This study was carried out in rural properties from Dois Vizinhos, Itapejara D’Oeste, Verê and São Jorge D'Oeste citties, Paraná State, Brazil. It was action plan was established with the rural communities through gathering information with agents considered key in the process, it seeking the greatest number of farm-ers who had their properties in the native fruits as pitanga, jabuticaba, uvaia, cereja-do-mato, guabiroba, guabiju, sete capote, goiaba serrana, araça amarelo e vermelho trees. Semi-structured questionnaire was applied, which concerned issues of presence, handling and use of Myrtaceae fruit trees on their properties and informed consent term. There was a survey of the number and native fruits present in each property. The characterization of each household in terms of diversity handled and used in native fruit was performed. It was realized the soil col-lect in 200 properties with the presence of at least some native fruit tree naturally occurring, in order to determine the preference of the species for the chemical characteristics of the soil. The four citties have native fruits trees in quantity and diversity for the creation of on farm net conservation, with farmers demonstrating knowledge of their role as guardians of this heritage of humanity.
