Education and community are currently intertwined, so that social practices, situated problems and emancipation processes have, more and more, entered in the school environment. Considering this context, the expansion of studies focusing on family literacy becomes necessary for the mobilization of alternatives and actions in this area. This research forms part of the project "The habitus of study: builder of a new reality in metropolitan Natal" (CAPES/OBEDUC/UFRN) and the program "Literacies and public policies: the family at school" (MEC/PROEXT/UFRN). In view of the chosen object – family literacy – therefore, we try to: 1) discuss actions implemented in a family literacy program, with specific reference to create literacy resources to register, discuss material, events, texts, 2) actions and promote forms of interaction by the family in the school environment; 2develop bonding strategies between school and families; 3) point the impact of such experiences of family literacy. To achieve these objectives, we base the discussion on theoretical contributions of the New Literacy Studies (STREET, 1984; McLAREN, 1988; BARTON & HAMILTON, 1993; KLEIMAN, 1995, 2000), focusing on Family Literacy and Literacy Project issues. Regarding to the research paradigm, we consider the Applied Linguistics field of study and we take the qualitative model (ERICKSON, 1990; BORTONI-RICARDO, 2008), with ethnographic critical approach (MOITA LOPES, 1993; THOMAS, 1993; HEATH & STREET, 2008). We understand, through our analysis, that families have much to contribute to the reality of schools, and, having seen relevance and value, these collaborators participate and act in support of the actions and the student’s education, even in the midst of complex routine situations. Still, we have learned that dialogues and activities with the community are necessary, looking forward to having involvement, local knowledge and the construction of shared learning; following this path, the collaborative environment is produced and the collaboration is effective.

The increasing demand for Internet data traffic in wireless broadband access networks requires both the development of efficient, novel wireless broadband access technologies and the allocation of new spectrum bands for that purpose. The introduction of a great number of small cells in cellular networks allied to the complimentary adoption of Wireless Local Area Network (WLAN) technologies in unlicensed spectrum is one of the most promising concepts to attend this demand. One alternative is the aggregation of Industrial, Science and Medical (ISM) unlicensed spectrum to licensed bands, using wireless networks defined by Institute of Electrical and Electronics Engineers (IEEE) and Third Generation Partnership Project (3GPP). While IEEE 802.11 (Wi-Fi) networks are aggregated to Long Term Evolution (LTE) small cells via LTE / WLAN Aggregation (LWA), in proposals like Unlicensed LTE (LTE-U) and LWA the LTE air interface itself is used for transmission on the unlicensed band. Wi-Fi technology is widespread and operates in the same 5 GHz ISM spectrum bands as the LTE proposals, which may bring performance decrease due to the coexistence of both technologies in the same spectrum bands. Besides, there is the need to improve Wi-Fi operation to support scenarios with a large number of neighbor Overlapping Basic Subscriber Set (OBSS) networks, with a large number of Wi-Fi nodes (i.e. dense deployments). It is long known that the overall Wi-Fi performance falls sharply with the increase of Wi-Fi nodes sharing the channel, therefore there is the need for introducing mechanisms to increase its spectral efficiency. This work is dedicated to the study of coexistence between different wireless broadband access systems operating in the same unlicensed spectrum bands, and how to solve the coexistence problems via distributed coordination mechanisms. The problem of coexistence between different networks (i.e. LTE and Wi-Fi) and the problem of coexistence between different networks of the same technology (i.e. multiple Wi-Fi OBSSs) is analyzed both qualitatively and quantitatively via system-level simulations, and the main issues to be faced are identified from these results. From that, distributed coordination mechanisms are proposed and evaluated via system-level simulations, both for the inter-technology coexistence problem and intra-technology coexistence problem. Results indicate that the proposed solutions provide significant gains when compare to the situation without distributed coordination.

The fish, Hoplias malabaricus (Osteichthyes: Erythrinidae) and armored catfish, Hypostomus pusarum (Loricariidae) are of freshwater origin from the neotropical region, and are considered ecologically and economically of important. This work investigated the trophic strategies, the morphology and histology of the digestive tract of these fish captured from the Marechal Dutra reservoir, Acari, the semiarid region of Rio Grande do Norte, Brazil. A total of 133 individuals of H. malabaricus and 118 specimens of H. pusarum were analyzed. The two study species occupy different levels in the food chain and spatial distribution in the water column of the reservoir. The results of this study are presented in the form of four scientific papers. The first article describes the morphology and histology of the digestive tract and the feeding habits of H. malabaricus (Bloch, 1794). This fish has a short intestine, with an intestinal coefficient of 0.72 ± 0.09. The dietary importance index indicates that H. malabaricus feeds preferentially on animal matter, especially on fish (72.8%) and prawns (27.2%). The histology of its digestive tract confirms the carnivorous feeding habit. The second article discusses about the pioneering work on the feeding strategy and the characterization of anatomy and histology of the digestive tract of H. pusarum. The intestine of this fish is long, with an intestinal coefficient of 10.8±0.7. The dietary importance index indicates that H. pusarum feeds preferentially on organic matter in decomposition (88.7%) and on filamentous microalgae and diatoms (11.3%). The third article compares the morphological aspects of the digestive tract of H. malabaricus and H. pusarum, in relation to their food habits. The arrangement of the digestive organs in both species is directly related to the shape of the peritoneal cavity and the form of the body. The short intestine of H. malabaricus and the long intestine of H. pusarum are associated with their feeding habits. The morphology of the digestive tracts of H. malabaricus and H. pusarum confirm their food habits, carnivorous and detritivorous / herbivorous, respectively. The fourth article discusses the food and reproductive aspects (length and weight, length-weight relationship, type of growth and sex ratio) of H. pusarum. This species has a negatively allometric growth, with the predominance of females in the sampled population. H. malabaricus inhabits the pelagic environment and is a carnivore, while H. pusarum, lives in the benthic environment and is characterized as a detritivore/herbivore. Each species studied shows a very different diet, without trophic competition between them. The morphological and anatomical structures of the digestive tract reflect their feeding strategy.

Health promotion is opposed directly to the biomedical model and established by intersectoral action, with collective and interdisciplinary approaches, considering the subject in their life contexts. Build healthy territories is to promote health, which necessarily includes intersectoral coordination and community mobilization. The health and education sectors can work together to promote health, developing so articulate actions and practices involving the subject in its territory of life and work. This study aimed to design and experience of health promotion strategies in school and Basic Health Units Family in Uberlândia - MG, from intersectoral relationship and community mobilization. The methodological research route was action research, or research intervention, because while researching already applied the ideas to solve problems through collective action. The research began in the Municipal School of Basic Education Prof. Eurico Silva, with the Health Centre's deployment to carry out surveillance and health promotion with active participation of students, involving all subjects of the school, students, teachers and other staff in the context of everyday life, which extrapolates the school walls, reaching the family and social groups in the community to which they belong. The health observatory has the objective existence with the establishment of the working groups, which at first were "healthy eating" and "drug-free world" and later, "dengue". The themes were chosen by the participants of the Health Centre, in which each is involved preferably. The second part of the research started with the approach between the Centre for Health and the health units (UBS and BFHU). The proposal was that the schools and the health nurse unit together should undertake prevention and health promotion, combating Aedes aegypti with intersectoral coordination and community mobilization. For it was crucial the involvement of ACS, ACE, ASE and the nurse coordinator of the Health Unit in creating community networks in the territory. home visits, community mobilization and intersectoral coordination: a training course in all BFHU and UBS teams with the following subjects was conducted. At this stage, were the Health Units that should approach the schools, in order to provide community networks to fight Aedes aegypti in each territory. The results and the scope of this experiment could only be brought to fruition because the Board of Health Surveillance and Care Coordination council of Basic embraced the proposal and helped in its implementation. It remains to continue consolidating this process of work in health units of primary care and the elementary schools, replicate the Health Centre's experience at school. The conclusion of this work is that schools and care facilities to health together with intersectoral coordination and community mobilization supported by community networks, can carry out prevention and health promotion, from a health model that considers the social determinants of health and overcoming hygienist model / sanitarian.

O uso das mídias sociais digitais como meio de divulgação de produtos, serviços e conteúdos organizacionais tem crescido nas últimas décadas e ganhou especial atenção nos planejamentos de comunicação organizacional e nos estudos acadêmicos sobre o tema. Nesse sentido, o segmento de empresas esportivas atua com destaque, despertando o interesse e a empatia do consumidor. Por meio de análise bibliográfica e estudo empírico, esta pesquisa teve como objetivo investigar as ações de comunicação mercadológica do segmento esportivo no ambiente digital conectado, através de um estudo de caso múltiplo das empresas Nike e Adidas. Para a obtenção dos dados, foram realizadas entrevistas em profundidade com profissionais do mercado e aplicado um protocolo de investigação de redes sociais digitais nos perfis das duas empresas. Após a coleta dos dados, estes foram analisados à luz das teorias estudadas nos capítulos iniciais (que abordaram temas como comunicação organizacional, comunicação digital, esporte e comunicação esportiva), e foi possível concluir, entre outros pontos, que, no universo do segmento esportivo, a comunicação digital conectada não prioriza o diálogo com seus públicos de interesse, sendo essencialmente baseada na divulgação unilateral de conteúdos, nem tampouco explora a potencialidade de cada uma das plataformas digitais disponíveis, replicando conteúdos em diferentes ambientes. Ficou evidente, também, o uso dos elementos constituintes do universo esportivo como argumentos estratégicos de comunicação das empresas, decorrente de sua capacidade de estreitar os laços relacionais com os públicos de interesse, por meio de seus apelos simbólicos de fácil identificação social.

Compreender as estratégias comunicacionais e simbólicas adotadas no desenvolvimento de rótulos das embalagens de vinho com foco em sua exposição no ponto de venda foi o objetivo geral deste trabalho. Foram abordados conceitos básicos sobre o universo do vinho e o imaginário a ele relacionado. O rótulo é o principal elemento de diferenciação neste produto, já que as garrafas de vinho são muito similares, sendo ele o responsável em persuadir o consumidor quando o produto está no ponto de venda. O rótulo é o componente “vendedor”, a “última chance” para motivar o consumidor a colocar o vinho em sua cesta de compras. A forma como este componente e seus conteúdos são desenvolvidos sob o ponto de vista gráfico e simbólico foi o objeto desta pesquisa qualitativa que utilizou como metodologia, referências bibliográficas e documentais nos dois primeiros capítulos. No terceiro capítulo, foi realizada uma análise de conteúdo gráfico e simbólico dos rótulos de uma amostragem intencional de vinhos. A seguir, foi aplicada uma pesquisa experimental empírica de alguns vinhos junto a degustadores para avaliar se a percepção e identificação dos rótulos podem gerar avaliações diferentes após uma primeira degustação "às cegas

This paper presents a survey conducted through collaborative work, which took place in a suburb school in the city of Uberlandia-MG. The research is characterized as case study and has a qualitative approach. Had the objective to look for different strategies of teaching and learning through the use of technology in pedagogical practice. Regarding the methodology in this research, we analyzed the work with the support of blogs, whose pages were used for student records and discussions directed to the geometry content. The students who were attending the fifth (5th) year of elementary school were invited to participate in this project. However, the research subjects were only those students who accepted the invitation to participate in the study through statement signed by parents. The project was developed with 30 students in the second half of 2014 and another 30 in the first half of 2015. The physical space at school, where most of the project activities were done was at the computer lab. In the process of compiling the data, at school, the following instruments were used: field notes produced by the entire project team, photographs and footage of the activities produced in the computer lab and in classroom (recorded by the research team) questionnaires, interviews, virtual space records: the blogs. The results of this research mainly focused on the analysis of the fifth year student‟s productions records in blogs. Regarding the conclusion, the research has shown that blogs, software and differentiated dynamic studies attracted the student‟s attention, leaving them mostly instigated by the unknown. Gradually, students built their own knowledge from their mistakes and successes. The entire work process enabled the computer lab to be an environment that is used not just to solving computerized and tedious drills. The blogs production work in groups, developed in students the reading and writing of both the mother language as symbols and mathematical nomenclature. The interaction between students became noticeable throughout the project, since it provided the student‟s personal growth, respect, tolerance and mutual cooperation. In this sense, we concluded that the project greatly contributed to the students' literacy process in the mother language, mathematics and computer literacy.

A transformação de elementos naturais em alimentos foi, é e será um tema central na actividade humana, convocando perícia, recursos, objectos e cultura, construindo em seu redor toda uma sociabilização e estabelecendo a refeição como um cerne civilizacional. Neste cenário, ritualizado na cozinha e na sala, convergem os mais diversos elementos disponibilizados pela sociedade contemporânea para produzir a refeição e dele resultam os mais diversos resíduos. Numa sociedade, em que a consciencialização da finitude dos recursos aliada ao aumento demográfico exponencial, gerou uma atitude ecológica que se tenta difundir e aumentar num panorama multicontraditório, todas as contribuições ganham uma urgência e validade significativa, sendo neste contexto que um trabalho de investigação pelo design, dedicado ao aumento de eficiência na confecção e consumo de refeições, assume a sua contribuição. Desde a utilização da tampa até aos mais recentes electrodomésticos, que a necessidade de uma maior eficiência energética se manifestou, embora de uma maneira difusa e colateral num contexto dominado pela qualidade, diversidade gastronómica e tempo de confecção. Pela análise das práticas, dos objectos e do espaço utilizados, verifica-se que existe um potencial de economia de recursos, que se pode obter pelo design de objectos e processos, relevantes para a refeição, que alarga e complementa as acções já implementadas, constituindo uma investigação em design que aborda várias dimensões desde aspectos históricos à produção de novos objectos e processos. Um olhar renovado e orientado para a eficiência coloca questões que, não pondo em causa aspectos qualitativos e culturais da refeição, poderão modificar e/ou complementar objectos e processos, melhorando práticas, potenciando espaços e relações. A concretização de cinco objectos e as pistas de investigação sugeridas demonstram a pertinência desta proposta e são o culminar deste trabalho.

A qualidade está na base do sucesso no mundo empresarial, sendo um fator de competitividade e de diferenciação entre organizações. No contexto das Instituições Particulares de Solidariedade Social, a aposta na qualidade é também uma realidade. No entanto, estas instituições enfrentam diversas dificuldades no processo de implementação do sistema de gestão da qualidade (SGQ) ISO 9001. De entre estas, destaca-se o difícil acesso à metodologia, crenças impostas, culturas resistentes à mudança, desconhecimentos e receios, que resultam em custos avultados para as organizações, dado o recurso frequente a empresas de consultoria. Como tal, o presente trabalho de investigação pretende salientar as principais dificuldades no processo de implementação da norma ISO9001:2008 em IPSS e dar o seu contributo para a clarificação da polémica que envolve a certificação desta norma, mediante a criação de um kit, com todas as ferramentas necessárias à implementação da norma. Por conseguinte, e para dar resposta ao objetivo proposto, procedeu-se numa primeira instância à realização de inquéritos a 29 organizações certificadas pelas normas ISO 9001:2008 e/ou EQUASS (European Quality in Social Services), de forma a apreender as principais dificuldades no processo de implementação da norma nas várias IPSS. Esta análise permitiu concluir que, os principais fatores que dificultaram a implementação do sistema de gestão da qualidade, segundo a norma ISO 9001:2008, são essencialmente a falta de tempo e/ou disponibilidade, assim como a dificuldade de interpretação da norma. Como tal, as organizações necessitam de ferramentas de auxílio que as apoiem e esclareçam no processo de implementação do sistema da qualidade. Neste sentido, elaborou-se o kit de implementação “Qualifica”. Este é constituído por um manual e um CD interativo com documentos, formações e ferramentas para a implementação do sistema, cujo objetivo é esclarecer, encaminhar, orientar e simplificar todo o processo de implementação da norma e utilizando uma linguagem simples e acessível. Para finalizar, a viabilidade do KIT “Qualifica” foi devidamente validada através da sua aplicação numa IPSS não certificada. Após a revisão do sistema implementado na IPSS em estudo, conclui-se que o KIT "Qualifica" ofereceu todas as bases e todos os recursos necessários para o bom entendimento, encaminhamento e implementação da norma, provando a sua potencialidade como ferramenta auxiliar fundamental que qualquer organização poderá no futuro utilizar.
