O presente trabalho propõe um entendimento sobre as relações interpessoais entre os sujeitos envolvidos na construção e execução do projeto pedagógico de Educação na modalidade a distância sob uma perspectiva etnometodológica e multirreferencial de educação. Propomos identificar como as relações se estabelecem no cotidiano da EAD, quais são seus agentes organizacionais e como estes se interagem na estruturação do trabalho, uma vez que a EAD exige uma complexidade de profissionais de diferentes saberes para a concretização de seus objetivos. Tomando como referência os cursos de educação a distância da UMESP, pretendemos, por meio de observação, relatórios, aplicação de questionários e entrevistas, identificar como cada agente se vê e se percebe no processo, e de que forma entende e reconhece o outro no desenvolvimento das atividades do referido curso. Utilizando como referência o percurso realizado na elaboração e operacionalização de uma teleaula desejamos reconhecer os processos comunicacionais entre o grupo de profissionais técnicos, dos gestores, dos docentes e discentes dentro da organização acadêmica, analisando suas conexões e rupturas, assim como a abrangência e importância de suas funções na prática diária.(AU)

Considerando a relevância do tema nas discussões acerca da educação e novas tecnologias na sociedade contemporânea, a presente pesquisa de cunho exploratório, propõe compreender relação dos adultos e crianças com o computador e como ele media (ou não) está relação. Tomando os pais e a educadora como imigrantes e as crianças como nativos digitais do grupo do 1º no do EF I, de uma escola da rede particular de ensino, em São Bernardo do ampo. É uma pesquisa quantitativa na medida em que estuda frequência com que os dados aparecem entre o grupo de participantes e qualitativa uma vez que recorre a estratégias de coleta de dados tais como: roda de conversa com os educandos; questionário, e-mails e grupo de discussão com os pais (pai ou mãe); questionário, e-mails e entrevistas com a educadora. E como aporte teórico para as reflexões desta pesquisa autores como: BABIN & KOULOUMDJIAN (1989); CHAVES & SETZER (1980); HUIZINGA (2001); LÈVY (1993; 1996; 1999); KENSKY (2003; 2007); MORAN (1987; 2007); PAPERT (2008); VALENTE (2002); SANCHO (1998); QUEIROZ (1999), SÁ (2001) que contribuíram na medida em que possibilitaram uma conversa entre suas ideias, concepções e com as vozes dos participantes da pesquisa. Os resultados caminham para compreensão de que o computador para os educandos está atrelado à relação entre: infância, experiência, ludicidade como elementos para a construção do conhecimento; para os pais uma possibilidade ainda em adaptação, mas que requer orientação; e para a educadora a tecnologia parece ainda estar nos limites do campo da resistência, provalvelmente em decorrência da incongruência entre qualificação e políticas de trabalho docente. O trabalho deixa questões, esperando-se incentivar, com isso, novos estudos.

Estudos em ambiente laboral acerca do comportamento humano e saúde no trabalho, bem como a melhor forma de se aplicar as competências e habilidades do trabalhador, vêm ganhando maior corpo devido à crescente busca por melhores resultados organizacionais, ao aumento da competitividade no mercado e à necessidade empresarial de atingir melhor desempenho de suas equipes. Gestores procuram por recursos e inovações a fim de tornar possível o alcance das metas organizacionais. Empregados mais capacitados, satisfeitos e envolvidos com seu trabalho são também aqueles que têm maior comprometimento afetivo com a organização. Para a empresa, isto pode significar um aumento da produtividade, o rebaixamento do número de absenteísmo e turnover. A dimensão saúde no trabalho ganha relevância porque bem-estar no trabalho significa também empregado mais feliz, com menor probabilidade de adoecimento físico, psíquico ou moral, reduzindo custos relativos à restituição da saúde do trabalhador. Por outro lado, estudo realizado sobre a inteligência emocional em gestores sugere que pessoas com alto nível deste tipo de inteligência são capazes de ter relacionamentos mais profundos e constituir uma rede social mais segura, ajudar os outros de seu grupo, bem como desenvolver uma liderança onde se possa construir uma equipe coesa e uma comunicação mais efetiva com os outros e levar a cabo planos estratégicos empresariais com mais eficiência. Este estudo teve como objetivo geral analisar as relações entre as habilidades da inteligência emocional e as dimensões de bem-estar no trabalho. A pesquisa foi realizada em uma empresa do setor de plásticos e metalurgia, em uma amostra constituída por 386 participantes dos sexos masculino e feminino, com faixa etária entre 18 e 58 anos. Foi utilizado para a coleta de dados um questionário composto de quatro escalas que mediram os três componentes de bem-estar no trabalho e as habilidades da inteligência emocional. Os resultados do estudo revelaram que apenas três habilidades da inteligência emocional tiveram correlações significativas com as dimensões de bem-estar no trabalho: empatia, sociabilidade e automotivação. Foram observadas correlações mais significativas entre sociabilidade e bem-estar no trabalho. Portanto, o bem-estar no trabalho parece associar-se às habilidades intelectuais e emocionais dos trabalhadores de serem empáticos, manterem-se automotivados e, especialmente, de estabelecerem e conservarem suas amizades (sociabilidade)

No campo científico, a busca por uma maior compreensão acerca de bem-estar no âmbito do trabalho é a tônica do momento, reunindo estudiosos das mais diferentes áreas que demonstram interesse pelo tema. No contexto empresarial, o papel dos programas de promoção da saúde e qualidade de vida torna-se marcante quando se deseja o crescimento da produtividade e do bem-estar dos trabalhadores, considerando a obtenção de resultados crescentes, pela empresa, como fundamentais para que as melhorias nas condições, organização e relações de trabalho ocorram permanentemente. Ou seja, as empresas entendem que com o investimento nesses programas a produtividade deve aumentar, gerando recursos, para que esta se sinta estimulada a continuar investindo no bem-estar dos empregados. Este estudo teve como objetivo promover uma análise sobre as relações entre bem-estar no trabalho, representado por satisfação com o trabalho, envolvimento com o trabalho e comprometimento organizacional afetivo; e freqüência a programas organizacionais de promoção da saúde. A amostra foi constituída por 117 trabalhadores de uma indústria multinacional química e farmacêutica, situada na Grande São Paulo, sendo 53 do sexo masculino e 64 do sexo feminino, com idade média de 30,28 anos, dos quais 63 eram solteiros, 46 casados e oito registram outro estado civil. Para desenvolvimento deste estudo, utilizou-se como instrumento um questionário composto por quatro escalas que mediram satisfação no trabalho, envolvimento com o trabalho, comprometimento organizacional afetivo e freqüência de participação em programas de promoção da saúde, realizados na empresa. Todos os dados recolhidos por meio do instrumento eram numéricos, o que permitiu sua análise eletrônica pelo SPSS, versão 13.0 para Windows. Nessa categoria de dados incluem-se os de descrição da amostra, os referentes a bem-estar no trabalho e freqüência aos programas de promoção da saúde. Foi criado um banco de dados para realização das análises descritivas (freqüências, percentuais, médias e desvios-padrão) e de correlação bivariada (r de Pearson). Os dados que permitiram descrever os programas de promoção da saúde promovidos pela empresa foram obtidos por meio de entrevista com a gerente de responsabilidade social, análise do relatório da empresa e de folhetos elaborados para divulgação e registro desses programas. Um total de cinco categorias de programas foi identificado: benefícios, atividades físicas, saúde, atividades culturais/lazer e ações comunitárias. A maior freqüência aos programas ocorreu na categoria benefícios, pela presença constante no restaurante da empresa. Os resultados deste estudo revelaram que grande parcela do bem-estar no trabalho especialmente no que tange o envolvimento com o trabalho, comprometimento afetivo com a organização, bem como satisfações com os colegas, com a chefia e com o próprio trabalho praticamente independe dos programas de promoção da saúde promovidos pela empresa. Por outro lado, participação em programas de promoção da saúde que incluem as categorias de benefícios, saúde e ações comunitárias, relacionou-se a satisfações com promoções e com salário

O conflito trabalho-família é um fenômeno freqüente nas sociedades atuais em que homens e mulheres dividem responsabilidades familiares e profissionais. A sua direção pode ser unidirecional ou bidirecional, ou seja, da família para o trabalho, do trabalho para a família ou simultaneamente de uma esfera para outra, afetando sensivelmente as relações familiares e as relações nas organizações, sendo possível afetar diretamente o bem-estar dos indivíduos. Este é um estudo de natureza quantitativa e com desenho transversal. O critério para a escolha de participantes foi o de conveniência. O objetivo geral desta pesquisa foi analisar as relações entre conflito trabalho-família (CTF), bem-estar subjetivo (BES) e bem-estar no trabalho (BET). O estudo contou com a participação de 174 trabalhadores em uma amostra diversificada de profissionais do segmento privado, público e de ONG, sendo 52,9% do sexo feminino, com idade média de 38,29 anos (DP=11,22). Para a obtenção dos dados optou-se por um questionário abrangendo as três variáveis do estudo contendo duas escalas para aferir as dimensões de BES, uma escala para aferir BET e uma escala para aferir CTF/CFT. Para a análise dos dados foi usado o SPSS, versão 20. Foram calculadas frequências, percentuais, médias, desvios-padrão, e índices de correlação, bem como índices de precisão das medidas usadas (Alpha de Cronbach). Os resultados apontaram para uma maior interferência do trabalho na família do que da família no trabalho. Essa interferência foi significativa tanto para o bem-estar no trabalho, quanto para o bem-estar subjetivo, alterando o envolvimento com o trabalho e gerando sentimentos de infelicidade, desânimo e angústia em relação as suas realizações pessoais, e ao futuro. Quanto maior o conflito trabalho-família, menor é o bem-estar no trabalho e menor é o bem-estar subjetivo desses participantes.

Este estudo teve por objetivos, identificar a percepção do padrasto sobre suas relações com seu(s) enteado(s) e identificar a percepção do padrasto acerca da sua função e papel na família. Utilizou-se de uma investigação clínica de referencial psicanalítico que levantou os dados por meio de entrevistas semi-dirigidas e do Desenho de família com estórias, em 3 participantes adultos e que eram padrastos. Os atendimentos foram realizados em ambiente de consultório, respeitando-se questões técnicas e éticas da pesquisa e da Psicologia em especial, tais como sigilo e consentimento dos participantes. A análise do conteúdo mostrou que havia peculiaridades em cada caso estudado, entretanto, havia fatores comuns em seus sentimentos e ações sobre a família e enteados: a) houve uma ambivalência pois tanto se perceberam como homens provedores e orientadores dos filhos e enteados, quanto havia também uma a percepção de que os sentimentos pelo filho biológico eram diferentes daqueles sentidos por seus enteados. b) todos os padrastos revelaram entraves nas relações por uma não definição clara de seu papel e função no contexto familiar, muitas vezes reforçado pelas esposas- mães, tidas como aquelas que detém o poder sobre o filho/enteado e, esta confusão gerava rivalidade entre padrasto e enteado, numa disputa pelo amor da esposa e mãe. c) do ponto de vista psíquico, foi observado que muitos conflitos os remetiam aos períodos precoces do desenvolvimento, especialmente à resolução edipiana, como numa reedição; assim, o exercício da função de padrasto se dá à base da qualidade de suas relações com seus pais na infância tal como se dá no exercício da paternidade consangüínea. De modo que, a função de padrasto, assim como a paterna se dá por um compromisso evolutivo . Sugerem-se outros trabalhos, pois se entendeu que esse tipo de estudo relacionado à Psicologia do desenvolvimento pode auxiliar em ações de saúde e prevenção em saúde mental.

A sporttermékek iránti kereslet kialakulására a sportszocializáció meghatározó befolyással bír. A sport kiemelkedő szerepet játszik a mai modern társadalomban. Jelentős gazdasági súlyt képvisel, továbbá lehetőséget ad a személyes fejlődésre és a társas kapcsolatok kialakítására, ápolására. Az egyéni személyes előnyök mellett a sportolás támogatása révén a társadalom egészségi állapotának költséghatékony megőrzése is biztosítható. Ezzel együtt hazánkban alacsony a szabadidősportban való részvétel, a lakosság egészségi állapota romlik, az ülő életmód egyre terjed. Az elvégzett kutatás célja az volt, hogy olyan ismeretekre tegyen szert, amelyek segítségével megérthető a sportolást befolyásoló legfőbb tényezők hatása, így az egyén szűk környezetének (család, barátok, iskola) jelentősége, a társas befolyás hazai jellegzetességei. Ezek az ismeretek elősegíthetik mind a profit, mind a non-profit szféra számára a lakosság sikeresebb megszólítását, hozzájárulva egy aktívabb társadalom megteremtéséhez. _______ Sport socialization has high relevance to generate demand for sport. Sport plays an important role in today’s modern societies. It has enormous economic significance and provides opportunity for personal development and for establishing new or keeping existing social relationships. Besides individual personal benefits, supporting sport also ensures the costefficient maintenance of good health on a social level. However sport participation and sport spectatorship are both low in Hungary. At the same time the health status of residents are worsening and the society is characterized by a sitting, sedentary lifestyle. The goal of the study is to gather information on the primary factors influencing sport participation, especially the significance of the close social environment of the individual (family, friends and education). Understanding why people participate in sports and how they can be motivated to do so is of primary importance to both the private and the state sector, explained by business interest and by the need to ensure the healthy operation of the society.

Cattleya granulosa Lind is a large and endemic orchid in Atlantic Forest fragments in Northeast Brazil. The facility of collecting, uniqueness of their flowers, which have varying colors between green and reddish brown, and distribution in coastal areas of economic interest make their populations a constant target of predation, which also suffer from environmental degradation. Due to the impact on their populations, the species is threatened. In this study, we evaluate the levels of spatial aggregation in a preserved population, analyze the phylogenetic relationships of C. granulosa Lindl. with four other Laeliinae species (Brassavola tuberculata, C. bicolor, C. labiata and C. schofieldiana) and also to evaluate the genetic diversity of 12 remaining populations of C. granulosa Lindl. through ISSR. There was specificity of epiphytic C. granula Lindl. with a single host tree, species of Eugenia sp. C. granulosa Lindl. own spatial pattern, with the highest density of neighbors within up to 5 m. Regarding the phylogenetic relationships and genetic patterns with other species of the genus, C. bicolor exhibited the greatest genetic diversity (HE = 0.219), while C. labiata exhibited the lowest level (HE = 0.132). The percentage of genetic variation among species (AMOVA) was 23.26%. The principal component analysis (PCA) of ISSR data showed that unifoliate and bifoliolate species are genetically divergent. PCA indicated a close relationship between C. granulosa Lindl. and C. schofieldiana, a species considered to be a variety of C. granulosa Lindl. by many researchers. Population genetic analysis using ISSR showed all polymorphic loci. The high genetic differentiation between populations (ФST = 0.391, P < 0.0001) determined the structure into nine groups according to log-likelihood of Bayesian analysis, with a similar pattern in the dendrogram (UPGMA) and PCA. A positive and significant correlation between geographic and genetic distances between populations was identified (r = 0.794, P = 0.017), indicating isolation by distance. Patterns of allelic diversity suggest the occurrence of population bottlenecks in most populations of C. granulosa Lindl. (n = 8). Genetic data indicate that enable the maintenance of genetic diversity of the species is complex and is directly related to the conservation of different units or groups that are spatially distant.

According to the Statute of Children and Adolescents (1990) children and adolescents are conceived as subjects of rights, with absolute priority and development peculiar condition. Thus, if these rights were violated or threatened, will be applied protection measures. Within these measures, in that Statute, the foster institutional is proposed, with transitional and exceptional character. When the child goes out from family and community life, and she is upheld in an institution, the child is placed in a new development context, therefore, with new people, new places, and new relationships. According with Socio-Historical Psychology, theoretical support of this study, each context presents specific demands of socialization that influence child development and her subjectivity is constituted through the relations that the subject establishes in each context. These contexts bring challenges and proposals for the child and she needs to respond these. Then, whereas he is in relation to the other, in this moment, the subject is constituted, the interactions established during the foster institutional will be of paramount importance to the child. Among these interactions, we can cite situations involving aspects of moral development, specifically those that can ask (or not) the exercise of the virtues. About the intersection between these actions can then arise care actions beyond those involving the attending of an emerging need. The objective of this study is to investigate the presence of relation everyday permeated by care actions among children in foster institutional. For the scope of the objective three children were participated, with three years old and in foster care measure. The research is qualitative and the procedure for building the corpus was, mainly, the participant observation. Procedures with video and history in books were also used as supplementary procedures. The analysis of the corpus was made through Thematic Content Analysis, the episodes were grouped into analysis categories pre-and post-established. The preestablished were care actions related to body care, care actions related to socio affective aspects, and care actions related to body care and socio affective aspects simultaneously. The two post-established categories were dismemberment of the preceding categories, called care actions developed in child-child interaction, without the intervention of an adult, and care actions developed in child-child interaction, with direct intervention of the educator. The analysis indicated that in the everyday interaction between foster children, they identify the physical and emotional needs of each other foster member, and they are willing to help them in whatever way they can, emphasizing the importance of play and playful moments like mediators about these interactions. The care actions observed are based on children´s concepts and interpretations made from their experiences and largely refer to maternal care. The condition of being away from their family life can be an element that enables these actions. Finally, this study reaffirms the importance of designing the foster institution as a socialization and care space. It follows the importance of valuing and strengthening the positive aspects that arise in the relationships established by the children in this context, including the care actions, the research objective, which are components of the subjectivity of these children

Portuguese language textbooks, according to what has been preconized on the official document to education, have been configured on discursive genres imported from diverse spheres of human activity. Adverts, genre of ample social circulation, spread from the Advertising sphere to the schools and started being approached by these collectaneas as an object and a tool for teaching. Therefore, this research deals with the approach of ads in Portugese textbooks. These discursive practices matter for the impact or appeal they exert over the (new) consumers, among which High School students; for their representation in the capitalist system, which guides us on our relationships and social practices; and for the mix of languages that end up at their composition, once they encapsulate the spirit of our time, par excellence, the one from the verbal-visual genres. To understand the treatment given to these advertising pieces, from questions/commentaries related to them, two collections were selected by the Programa Nacional do Livro Didático – Textbook National Program (PNLD 2012) among the ones more used by public High Schools in Natal/RN. From Applied Linguistics, from mestizo, nomadic and inter/transdisciplinary identity (MOITA LOPES, 2009), this study falls within the discursive chain of the interpretive tradition of historical-cultural approach (FREITAS, 2010) and names the Bakhtin Circle and its language‟s dialogical conception as inescapable partners. The data of the colletaneas show that the genre approach can happen as concrete utterance, as linguistic artifact and as hybrid, at work with questions and without questions, with the predominance of its occurrence in the portion of the volume devoted to the study of grammar. In the literature chapters and production/interpretation of compositions, it insert is incipient or it doesn‟t happen in the volume. Such a provision has implications for multiliteracies (ROJO, 2012) of the citizen student, once the lack or the abundance of critical reading proposals for this genre, that demand from the student the exercise of knowledge that is necessary to the construction of linguistic and social meanings, can be responsible for guide to a more conscious consumerism (material and cultural) by the chief customers of the work under review. The approaches of the genres seems to indicate a gradual transition that such material have undergone, which means, from the focus on clauses to the focus on utterances, or even the approach as linguistic artifact to hybrid and the concrete utterance, in search of overcoming the traditional tendency of taking advantage of formal aspects of the language, to the detriment of enunciative ones, and for coming into harmony with the guidelines and parameters of teaching in contemporary times, bringing the school duties close to the rights in life.

The investigation analyze s the role of the municipalities in the ongoing development of literacy teachers, having as a field of study the municipalities of Jaguaruana and Palhano, both in the State of Ceará. The political - educational space adopted as a sample of the study is the p eriod between the years 2003 and 2006, when the emphasis on cooperative action among the federated entities is observed in the Government’s guidelines and Brazilian educational policies, showing the municipal presence in the implementation and execution of these policies. T he historical - dialectical materialistic perspective, understood as an analysis of the social reality as historical elaboration and product of the human praxis, is expressed as the required theoretical - methodological path. The investigatio n is operationalized through interconnected stages: one that involves bibliographical and documental analysis, in which the theoretical input of the research is added, as well as the Federal, State and M unicipal documents accessed ; and another, regarding t he field work, studying the specific character of the object and its mutual rela tionships in the municipalities . The research brings the notion of intergovernmental relationships and cooperative mechanisms as central theoretical tools and, dialoguing with them, ideas such as decentralization, municipalization and municipal autonomy are inserted into a theoretical/practical body, through which the historical and logical aspects of the object are detailed. The study describes and interprets the policies of on going development of literacy teachers with focus on the national guidelines formulated since the 1990’s and on the govern mental incorporation in the national and subnational spaces. In this sense, the analysis is based on the comprehension of the interrel ationship between the municipal policies and the p olicies created by the S tate or Federal G overnments in order to offer ongoing development of literacy teachers. Considering the investigated sample, it shows how the municipal role and the relationships bet ween the State and municipalities of Ceará have emerged, as well as their characteristics regarding the education management policies, taking into account the practices of municipalization and cooperation between the State and municipalities in their histo rical composition. It shows the practices which aim at the ongoing development of literacy teachers observed in the researched municipalities, pointing out the realities and specific marks left by municipal presence in the area, demonstrating the assigned role and the role played. Based on the points of view of the managers interviewed in the municipalities of Jaguaruana e Palhano, it is possible to note the meaning and effectiveness of the policies carried out. With such elements, it discusses the municipa l asymmetries in their homogeneities and heterogeneities rega rding the execution of their federative role. The analysis shows that th e role of the municipalities vary according to the historical, political and social interventions in each municipality. In the fields of formulation and execution of educational policies, the actions of the municipal governments, situated and with expressive interferences, reveal asymmetries in the sense that some municipalities have bigger autonomy and participate more effect ively in the production and distribution of policies than others. In terms of the researched realities, the study shows that taking care of the policies of ongoing development of literacy teachers is not a task that should be assigned exclusively to the mu nicipalities, nonetheless it is a role that they play with varying degrees of success. This role is in fact a joint competence of the federated entities, in the scope the Brazilian cooperative federalism.

On the evening of April 1, 1981, the city of Santa Cruz was taken by a flood that destroyed the spillway weir Santa Cruz and much of the city, causing the population of the lower areas to abandon their homes. Residences and closest to the dam, the river and the creek Trairi Sin streets were totally affected, and many of the houses and public buildings completely destroyed. Located in the state of Rio Grande do Norte, the city of Santa Cruz is marked by a very hot climate and semi-arid. With an average normal rainfall of 498.7 mm per year, the city is affected by drought since the beginning of its foundation, around the year 1831. For its development had continued, it was necessary that the population actualize various environmental interventions Nature, especially as regards the storage and distribution of water. Considering the process of occupying the space in question, as well as the relationships that human groups have with the natural environment, we aim to analyze how human interventions affect the environment around them, modifying it to meet their needs and interests. Thus, we intend to understand how media coverage enabled the construction of a framework of tragedy. We intend to observe how the occupation of Santa Cruz led to the modification of their surroundings, trying to discuss the effects of human intervention on natural disasters. Among the research sources include newspapers A República, Diário de Natal, Tribuna do Norte, O Poti and Folha de São Paulo, as well as interviews with the then mayor of Santa Cruz, Hildebrando Teixeira de Souza, and with the couple José Henrique de Pontes and Severina Aguida de Pontes, whose house was hit by the flood. We will also take messages from the state government, the minutes of the city council of Santa Cruz and reports produced by DNOCS on the construction of the weir and its survey after the flood.

The main inputs to the hippocampus arise from the entorhinal cortex (EC) and form a loop involving the dentate gyrus, CA3 and CA1 hippocampal subfields and then back to EC. Since the discovery that the hippocampus is involved in memory formation in the 50's, this region and its circuitry have been extensively studied. Beyond memory, the hippocampus has also been found to play an important role in spatial navigation. In rats and mice, place cells show a close relation between firing rate and the animal position in a restricted area of the environment, the so-called place field. The firing of place cells peaks at the center of the place field and decreases when the animal moves away from it, suggesting the existence of a rate code for space. Nevertheless, many have described the emergence of hippocampal network oscillations of multiple frequencies depending on behavioral state, which are believed to be important for temporal coding. In particular, theta oscillations (5-12 Hz) exhibit a spatio-temporal relation with place cells known as phase precession, in which place cells consistently change the theta phase of spiking as the animal traverses the place field. Moreover, current theories state that CA1, the main output stream of the hippocampus, would interplay inputs from EC and CA3 through network oscillations of different frequencies, namely high gamma (60-100 Hz; HG) and low gamma (30-50 Hz; LG), respectively, which tend to be nested in different phases of the theta cycle. In the present dissertation we use a freely available online dataset to make extensive computational analyses aimed at reproducing classical and recent results about the activity of place cells in the hippocampus of freely moving rats. In particular, we revisit the debate of whether phase precession is due to changes in firing frequency or space alone, and conclude that the phenomenon cannot be explained by either factor independently but by their joint influence. We also perform novel analyses investigating further characteristics of place cells in relation to network oscillations. We show that the strength of theta modulation of spikes only marginally affects the spatial information content of place cells, while the mean spiking theta phase has no influence on spatial information. Further analyses reveal that place cells are also modulated by theta when they fire outside the place field. Moreover, we find that the firing of place cells within the theta cycle is modulated by HG and LG amplitude in both CA1 and EC, matching cross-frequency coupling results found at the local field potential level. Additionally, the phase-amplitude coupling in CA1 associated with spikes inside the place field is characterized by amplitude modulation in the 40-80 Hz range. We conclude that place cell firing is embedded in large network states reflected in local field potential oscillations and suggest that their activity might be seen as a dynamic state rather than a fixed property of the cell.

This thesis analyzes the social relations of Cavalcante family of Gypsies who live in the city of Sobral, Ceará; especially as kinship relations are lived in a context marked by tensions and instability. From the domestic core ethnography conducted from January to June 2013, and observing the representations by gypsies around the family term, the goal is to show how these representations are activated to describe forms of solidarity between gypsies. To define themselves in terms of how a "big family", the ciganos to demarcate the non-Roma and prepare themselves for life in society codes that can be changed in the audience and situations. The paper discusses the role of family relationships in the forms of sociability and conflicts, matrimonial strategies, including non-gypsies, work practices, defining a gypsy lifestyle.

The present study has the objective of analyzing how the ways of dwelling influences the uses and the functional and symbolic appropriations of the urban space in Fortaleza city center, through the perspective of the residents and their relation with the living place. Scenarios of development and degradation of its urban space have marked the city center of Fortaleza. The intensification of the commercial and services occupation promoted through the years, paradoxically, the valorization of the land price and the devalorization of the residential use. Thus, the residential occupation was consolidated in a discontinuous way, being concentrated mainly in the external limits of the historical core of the neighborhood. The research is structured over the delimitation of an area and the selection of multifamily residential buildings, built since the 1960s, close to the central core of the neighborhood. The spatial configuration analysis of the selected residential buildings, and their relations with the urban surroundings and the land uses, reveals different aspects related to the urban vitality, producing impacts over the ways of dwelling constituted by the daily life of the residents. The study of the ways of dwelling involves the comprehension that the dwelling is beyond the private residential boundaries and the functional occupation. The conceptual base of this research is developed over the perspective that the dwelling represents a fundamental aspect of the human condition, allowing the person to relate with the space in an essential way (HEIDEGGER, 2012). In this perspective of the dwelling, the space reunites the mental and the cultural, the social and the historical, being marked by simultaneous logics of the conceived, the perceived and the lived space (LEFEVBRE, 2006). The development of this study, over the point of view of the neighborhood residents, is inserted in the perspective of the lived space, related to the concept of place, understood as a qualitative phenomenon, giving essence and identity to the space. The place of dwelling, marked by coexistences, is one of the structural elements of the urban land use, and potential for the rehabilitation of the central areas in big cities. Therefore, the study starts from the hypothesis that the location, the nearby land uses and the spatial configuration of the residential buildings affect the ways of dwelling, in other words the residents dissolve the boundaries of the shelter and experience the urban space, from the dwelling place. The requalification of the dwelling is opposed to the residential space based in functionality, in hierarchy, in self sufficiency, in standardization and in the reproduction of the urban space, materialized in the dense contemporary residential buildings, that are unrelated to the city. The stages of the research involved the spatial configuration analysis of the selected residential buildings and their surrounding, the land use mapping and interviews with the residents. The collected data allowed verifying that the buildings are located in areas presenting heterogeneous land uses, with a great number of residents and users. However, these aspects are not sufficient to promote the vitality of the public spaces in the neighborhood, since the people movement in the streets is controlled by the opening hours of the predominant commercial use in the area. The word of the residents, collected in interviews, indicate that the conservation conditions of the public spaces and the insecurity influences their everyday relations with the place of dwelling, affecting fundamental aspects for the dwelling requalification in the central area of Fortaleza.
