A literatura contemporânea na área de administração de negócios enfatiza a importância do ensino da inovação aos futuros profissionais das ciências gerenciais, visando capacitá-los para, também, gerir a mudança tecnológica. O objetivo desta pesquisa é examinar a oferta de disciplina relacionada à inovação, pelas Instituições de Ensino Superior, na área de Administração, Contábeis e Turismo, na graduação e nos cursos tecnológicos de Gestão, recomendadas pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior. Para tanto, foi desenvolvida uma pesquisa exploratória, com delineamento documental. A amostra que compõe esta pesquisa foi obtida a partir da análise das instiuições que oferecem disciplina cujo título contenha o terno “Inovação”. A partir desta amostra foram examinadas as ementas e respectivas bibliografias, obtidas nos websites das instituições de ensino. Foram realizadas buscas no banco de dados do e-MEC. Para efeito de fundamentação teórica esta pesquisa está baseada na Teoria do Crescimento Endógeno e no conceito schumpeteriano de desenvolvimento econômico baseado na inovação. Assim, dadas às bases teóricas de referência e a análise dos conteúdos descritos nas matrizes curriculares examinadas, pode-se observar um distanciamento entre a emergência do debate da inovação nos cursos que visam formar os profissionais nas atividades de administração, contabilidade e turismo, em nível de graduação e nos cursos tecnológicos de gestão e suas respectivas grades programáticas. De acordo com o resultado da amostra estudada, é possível inferir que, nos citados cursos, não haja ênfase no ensino da inovação, o que induz à conclusão da existência de uma lacuna no aprendizado da gestão de empresas cujo foco de negócio seja a inovação.

The Ionospheric Disturbances – TIDs – are irregularities on the ionospheric plasma propagating in speeds in the order of tens to a few hundreds of meters per second. This present study detected and characterized the TIDs of LSTIDs (Large Scale Travelling Ionospheric Disturbance) type at low latitudes during intense geomagnetic storms and its propagation over the Brazilian sector. This work also shows as being the first to report systematically propagation of gravity waves over Natal. For this purpose, we used ionospheric records obtained from type of digisonde CADI (Canadiam Advanced Digital Ionosonde) located in Natal and the type DSP (Digisonde Portable Souder) located in Cachoeira Paulista, Fortaleza and São Luis, whereupon we used a dataset of 12 years collected by INPE (National Institute of Space Research). In this study, both calm days, that preceded the storms, and the geomagnetically disturbed days were related during the years 2000 and 1012, which cover a period of maximum and minimum solar activity. And it is presented the variations that happened in the electron density from region F of the ionosphere over the Brazilian sector, especially near the Equator (Natal, Fortaleza and São Luis), caused by ionospheric disturbances in the equatorial region during intense geomagnetic storms, because, as we know of the literature in this area, this phenomenon contributes positively to the emergence of LSTIDs in the auroral region, which may move to the equatorial region where a few cases have been documented and studied systematically. From the observation of signatures if TIDs in ionogram records, a study of the morphology of these events was performed and compared with the main characteristics of the wave of this phenomenon during great magnetic storms, i.e., DST <(-200 nT) and KP > 6. Thus, we obtained the main characteristics of TIDs over our region, i.e., period, vertical wavelength, phase and propagation speed, as well as the delay of these disturbances compared to the beginning of the magnetic storms to the Brazilian Sector.

There are several abiotic factors reported in the literature as regulators of the distribution of fish species in marine environments. Among them stand out structural complexity of habitat, benthic composition, depth and distance from the coast are usually reported as positive influencers in the diversity of difentes species, including reef fish. These are dominant elements in reef systems and considered high ecological and socioeconomic importance. Understanding how the above factors influence the distribution and habitat use of reef fish communities are important for their management and conservation. Thus, this study aims to evaluate the influence of these variables on the community of reef fishes along an environmental gradient of depth and distance from shore base in sandstone reefs in the coast of state of Rio Grande do Norte, Brazil. These variables are also used for creating a simple predictive model reef fish biomass for the environment studied. Data collection was performed through visual surveys in situ, and recorded environmental data (structural complexity of habitat, type of coverage of the substrate, benthic invertebrates) and ecological (wealth, abundance and reef fish size classes). As a complement, information on the diet were raised through literature and the biomass was estimated from the length-weight relationship of each species. Overall, the reefs showed a low coverage by corals and the Shallow reefs, Intermediate I and II dominated by algae and the Funds by algae and sponges. The complexity has increased along the gradient and positively influenced the species richness and abundance. Both attributes influenced in the structure of the reef fish community, increasing the richness, abundance and biomass of fish as well as differentiating the trophic structure of the community along the depth gradient and distance from the coast. Distribution and use of habitat by recifas fish was associated with food availability. The predictor model identified depth, roughness and coverage for foliose algae, calcareous algae and soft corals as the most significant variables influencing in the biomass of reef fish. In short, the description and understanding of these patterns are important steps to elucidate the ecological processes. In this sense, our approach provides a new understanding of the structure of the reef fish community of Rio Grande do Norte, allowing understand a part of a whole and assist future monitoring actions, evaluation, management and conservation of these and other reefs of Brazil.

This paper focuses on the construction of the narrative for elementary school students, searching to identify strategies they employed in the production of narrative texts representative of miniconto genre. Therefore, we take a sample forty texts produced by students of 6 and 9 years of basic education, twenty in the 6th year students (ten public school and ten private school) and twenty students in 9th grade (distributed similarly between public education and private). In general, we aim to understand the mechanisms by which producers build their narratives, as well as providing input for analysis of textual production of this genre. This research is based on Functional-Linguistic assumptions of the American side, inspired by Givón (2001), Thompson (2005), Hopper (1987), Bybee (2010), Traugott (2003), Martelotta (2008), Furtado da Cunha (2011), among others. In addition, from the theoretical framework presented by Labov (1972) about the narrative, coupled with Batoréo contribution (1998), we observed the recurring elements in the structure of narratives under study: abstract, orientation, complication, resolution, evaluation and coda. Also approached, but that in a complementary way, the notion of gender presented in Marcuschi (2002). This is a research quantitative and qualitative, with descriptive and analytical-interpretive bias. In corpus analysis, we consider the following categories: gender discourse miniconto; compositional structure of the narrative; informativeness (discursive progression, thematic coherence and narrative, topical-referential distribution); informative relevance (figure / ground). At the end of the work, our initial hypothesis of the better performance of students in 9th grade, compared to 6, and the particular context of education in relation to the public context, not confirmed, since, in the comparative study revealed that the groups have similar performance as the construction of the narrative, making use of the same strategies in its construction.

A proteção do meio ambiente e a promoção de um desenvolvimento sustentável têm assumido um papel estabelecido e de crescente importância junto das organizações que, conscientes das suas fragilidades e pressionadas pela opinião pública, têm adotado sistemas voluntários de ação ambiental. A presente dissertação tem por base um estágio curricular que decorreu no período de outubro de 2013 a junho de 2014, numa Unidade Militar sob dependência da Marinha Portuguesa, o Depósito Munições Nato de Lisboa / Serviço de Armas Navais (DMNL/SAN). O estágio teve como objetivo principal a conceção e implementação de um sistema de gestão ambiental (SGA) com base no referencial internacional NP EN ISO 14001:2012. De acordo com o normativo foram definidos e implementados procedimentos e práticas de forma a dar cumprimento ao estabelecido nos requisitos - 4.1. (Requisitos Gerais), 4.2. (Política Ambiental), 4.3. (Planeamento) e 4.4. (Implementação e Operação). Assim, procedeu-se à revisão bibliográfica de conceitos subjacentes ao sistema de gestão ambiental e ao diagnóstico ambiental de referência, de modo a compreender os requisitos necessários para a conceção, desenvolvimento e implementação do SGA. Numa segunda fase foram identificados os aspetos ambientais significativos, realizado o levantamento de requisitos legais, estabelecidos objetivos e metas ambientais, desenvolvendo documentação necessária ao SGA. Para tal, foram realizadas reuniões, primeiramente de enquadramento da Unidade Militar e apresentação das instalações e atividades desenvolvidas. Ao longo do estágio foram também feitas reuniões para apresentação do trabalho desenvolvido e definição de objetivos e atividades necessárias à implementação do SGA. Na definição dos aspetos ambientais foram realizadas várias visitas às instalações nas quais houve contacto com os trabalhadores associados a cada tarefa de modo a compreender as atividades desenvolvidas e possíveis impactes. Com o objetivo de sensibilizar e contextualizar toda a guarnição, militares e civis, foram dinamizadas ações de formação e sensibilização no âmbito do desenvolvimento sustentável e gestão ambiental.O SGA do DMNL/SAN encontra-se em fase de implementação, sendo necessário proceder à realização de auditorias e revisão do sistema, bem como legalizar o registo da Unidade no portal da Agência Portuguesa do Ambiente, o qual não foi concretizado face a questões temporais e hierárquicas internas.

Esta investigação encontrou a sua fundamentação numa crescente preocupação sobre a questão da toxicodependência, uma problemática complexa, que até aos nossos dias não tem encontrado uma resposta segura para a sua resolução. O fenómeno da toxicodependência é um problema que acontece em toda a dimensão social. Nos últimos anos a incidência do consumo de drogas ilícitas tem aumentado de forma preocupante na nossa sociedade e em particular nas mulheres. Toda esta problemática da toxicodependência adquire dimensões ainda mais complexas e preocupantes nas situações de gravidez e de maternidade. Esta investigação tem como objectivo conhecer e analisar a experiência de vida e os sentimentos de mães toxicodependentes internadas numa comunidade terapêutica. A opção metodológica do estudo incide numa abordagem qualitativa, de natureza descritiva e de orientação fenomenológica, procurando deste modo conhecer melhor a globalidade dos fenómenos e a sua compreensão como experiência, tal como ela é vivida e tal como esta é definida pelas utentes. Entre outras conclusões, destacamos, a emergência de significações existenciais para a mulher a partir da experiência vivida no mundo da droga, assim como os sentimentos e emoções vividos pela experiência da maternidade. O internamento na comunidade terapêutica é vivido como positivo, ressaltando o crescimento pessoal uma vez que esta experiência proporcionou uma reflexão sobre a sua própria vida, perspectivando assim um projecto vida, um recomeçar.

The Federal Institution for Education, Science and Technology, in its historical path, has been living different changes. The transformations occurred along the way have been determined by coercive forces from the institutional environment, which has became more and more broad and complex throughout the time, obtaining diverse characteristics and new elements such as non institutional factors1 which started to contribute with the other changes. In this context, this work aims to study the isomorphic practices of the managers in the institutional changes process of the IFRN in 1998 and 2008, as of a theoretical coevolutionary perspective (CHILD; RODRIGUES; LEWIN; CARROL; VOLBERDA, 2003). This theory brings a new point of view for the organization analysis to the organizational studies, since it offers a non deterministic and non linear lection of the evolution process, which means, a coevolution. Thus, the organizations and their institutional and non institutional environment auto evolve, auto organize and auto reproduce. Therefore, the institutional and non institutional factors of the macro environment keep a continuous interdependence relationship with the organizations. For the means of this study, it is important to understand that is impossible to comprehend the object, the isomorphic practices, without considering that the previous institutional changes and its evolutions, its continuations and discontinuations, important in the coevolution process. As such, to call upon the institutional historical track is a fundamental aspect to materialize this study, for the recursive movement is indeed present in the coevolution. Another important point to make this research effective is that it is not possible to abdicate from the hologramatic view2 of this study, which considers the object, the isomorphic practices, part of the whole and this whole is also in the parts, therefore it is impossible to comprehend the object of study outside the context where it belongs. With this, as of the objective previously proposed, it is necessary to describe the characteristics of coevolution of the institutional changes related in 1998 and 2008; analyze the dynamic of the isomorphic mechanisms in its respective institutional change process; and describe the lessons learned which the isomorphic practices left to the IFRN, regarding its benefits and difficulties. All these transformations happened through coercive forces3 of the institutional environment. As of the Nineties, these forces became stronger, the environment became broader and more complex, with the emergency of new environmental factors. This study proposed to study the managing process and its practices, related to the micro environment, although it is required to articulate these actions, the demands and requirements from the macro environment. To make this research effective, semi structured interviews have been conducted with the managers who participated in both institutional change processes. In the results analysis, it has been possible to verify the particularity of each change, the one from 1998 with a strong normative action of the managers against coercive forces from the government for the search of recognition and the institutional legitimation and the one in 2008, which has been characterized by the normative action by managers in agreement with the coercive forces from the government, in favor of the government policy for the technological professional education. However, the results analysis it is possible to notice the evidence of a belonging feeling from the interviewed managers
