Devido ao contexto económico vivido actualmente, de muita concorrência e de incerteza, impõe-se a aposta em fazer diferente, em fazer melhor e a um menor custo. Tal caminho pode ser percorrido com recurso à criatividade e inovação resultando deste binómio elementos potenciadores de mais-valias para a empresa e para o consumidor. Será que o ambiente organizacional influencia o aparecimento de criatividade e inovação? A opinião de que o ambiente é realmente muito importante para tal acontecer é partilhada por vários autores. A cultura organizacional, a forma como é considerado o indivíduo dentro da organização, como é feita a gestão de talentos, a forma como são encorajadas as ideias de todos os indivíduos pode realmente ser um factor decisivo para facilitar e encorajar a criatividade e inovação na empresa. A abordagem empírica assenta num estudo qualitativo, para o qual foram seleccionadas três empresas. A selecção de duas das empresas teve em conta o seu posicionamento no mercado como empresas inovadoras e a terceira pelo facto do seu core business estar directamente relacionado com a criatividade. Através do estudo realizado conclui-se que a cultura e o clima organizacional, ou seja, a forma como é visto o colaborador, como lhe é dado poder de decisão, como é reconhecido o seu esforço, trabalho e empenho, influencia os níveis de criatividade e inovação dentro da Organização. ABSTRACT; Due to the current economic context, marked by a fierce competition and uncertainty, it is necessary to focus on making differently, better and cheaper. Such path can be followed using creativity and innovation. Profit-boosting elements for the company and the consumer. Does the work environment affect the occurrence of creativity and innovation? Several authors share the opinion that the environment is very important for that occurrence. The organizational culture, the way how the individual is perceived inside the organization, how the management of talents is made, the ideas from all individuals are seen, can be a major to facilitate and encourage creativity and innovation in the company.

This work is an ethnographic research with collectors women of Mangaba in the village of Ponta Negra in Natal - RN. This Women also known as Mangabeira's women reproduce a practice learned with their ancestors, collecting this fruit in the coastal tablelands forests and latter commercializing it in the local markets. This research uses the methodology of oral history and visual anthropology with presentation of collected images on board. It is intended to emphasize the botanical and environmental aspects of the Mangabeira plant, its ecosystem, territorial, economic and historical aspects of it, also the knowledge of this extractive practice of our immaterial culture.
Show de Mamulengos de Heraldo Lins: construções e transformações de um espetáculo na cultura popular
Resumo:
The theater of puppets is one of the many expressions of popular culture which is marked by ongoing constructions and transformations in its symbolic representations as well as its characters and performances. In the city of Natal/RN, there is a manipulator called Heraldo Lins, an artist who operates such puppets, and has been performing his puppet since 1992. Lins has his own look at how he produces his performances and seeks to adjust his puppets to social and rentable contexts. Lins‟s performances are tailor-made in accordance with the request of his customers, as he makes up the passages and lines of his puppets according to his audience. This research aimed to study how the Heraldo Lins Mamulengos Show is built, especially its changes. We note that Lins chooses to dismantle the symbolic values of the tradition in the regular puppet theater once he adapts to modern patterns, placing himself between the traditional puppet theater and the cultural industry. The work in camp was made through a methodological focused in a participative observation and an audiovisual registry

O que é a cultura estratégica? Será que a viragem cultural nos estudos de segurança a que se pode assistir nas últimas duas décadas faz sentido e pode ser aplicado de forma pertinente ao caso de Portugal? Iremos argumentar que sim. E para o demonstrar começaremos por procurar definir o que é e para que serve esta noção de cultura estratégica. Para depois defender que se a cultura estratégica pode mudar, porém, muda a custo, e é portanto natural para uma primeira avaliação da sua pertinência e desenho de um programa de pesquisa aplicada ao caso de Portugal comece por procurar detetar nos comportamentos, nas opções estratégicas de longo prazo traços definidores de uma cultura estratégica nacional informal, genérica, amplamente partilhada e de grande duração; a qual condicionou as perceções e preferências na prossecução dos interesses do Estado português, em particular quanto ao uso da força.

O uso de imagens de satélite e fotografias aéreas são cada vez mais comuns na obtenção de dados sobre recursos ambientais, como os cursos d?água. Deste modo, o presente trabalho objetivou comparar três diferentes produtos de Sensoriamento Remoto no mapeamento visual de drenagens e nascentes: imagens do satélite SPOT/Ikonos, imagens do programa Google Earth® e fotografias aéreas, na Microbacia Hidrográfica do Córrego do Ceveiro (MHC), localizada em Piracicaba/SP. Utilizou-se rede de drenagem presente em cartas topográficas do IGC/SP, escala 1:10.000, como base para comparação. Foram analisados dois fatores: comprimento de drenagem (CD) e número de nascentes (NN), sendo as análises realizadas apenas em caráter quantitativo. Para o CD, o produto SPOT se mostrou mais semelhante às cartas 1:10.000, apresentando 1,43% acima do CD existente nas cartas. Para o NN, a fotografia aérea mostrou o coeficiente mais alto, sendo esse o produto analisado que apresentou maior equivalência com o valor das nascentes observadas nas cartas.

This article describes the Robot Vision challenge, a competition that evaluates solutions for the visual place classification problem. Since its origin, this challenge has been proposed as a common benchmark where worldwide proposals are measured using a common overall score. Each new edition of the competition introduced novelties, both for the type of input data and subobjectives of the challenge. All the techniques used by the participants have been gathered up and published to make it accessible for future developments. The legacy of the Robot Vision challenge includes data sets, benchmarking techniques, and a wide experience in the place classification research that is reflected in this article.

In this article we describe a semantic localization dataset for indoor environments named ViDRILO. The dataset provides five sequences of frames acquired with a mobile robot in two similar office buildings under different lighting conditions. Each frame consists of a point cloud representation of the scene and a perspective image. The frames in the dataset are annotated with the semantic category of the scene, but also with the presence or absence of a list of predefined objects appearing in the scene. In addition to the frames and annotations, the dataset is distributed with a set of tools for its use in both place classification and object recognition tasks. The large number of labeled frames in conjunction with the annotation scheme make this dataset different from existing ones. The ViDRILO dataset is released for use as a benchmark for different problems such as multimodal place classification and object recognition, 3D reconstruction or point cloud data compression.

The incidence of toxic cyanobacterial blooms is one of the important consequences of eutrophication in aquatic ecosystems. It is a very common phenomenon in reservoirs and shrimp ponds in the State of Rio Grande do Norte (RN), Brazil. Cyanobacterias produce toxins which can affect aquatic organisms and men trough the food chain. Aiming to contribute to the studies of cyanobacterias in RN, we propose: a) to evaluate the toxicity of isolated cyanobacterias in important fresh-water environments; and b) to verify the effects of both natural and cultured blooms occurred in reservoirs for human supply and in the cladoceran Ceriodaphnia silvestrii. This study was carried out using samples of natural blooms occurred between March and October of 2004 in Gargalheiras Dam (08º L e 39º W), in July of 2004 in Armando Ribeiro Gonçalves Dam (06o S e 37o W) and in commercial shrimp ponds (Litopenaeus vannamei) located in fresh-water environments. The samples were collected with plankton net (20µm.) for identification, isolation and obtaining of phytoplanktonic biomass for liophilization and later toxicity bioassays. The toxicity of cultured samples and natural blooms was investigated through bioassays in Swiss mice. Quantification of cyanobacteria in samples was conducted following the Ütermol method, with 300mL samples fixed with lugol. The toxicity test with Ceriodaphnia silvestrii followed ABNT, 2001 recommendations, and were accomplished with natural hepatotoxic bloom s samples and cultured samples of both non-toxic and neurotoxic C. raciborskii. In this test, five newborns, aged between 6 and 24 hours, were exposed to different concentrations (0 a 800 mg.L-1) of crude cyanobacterial extracts during 24 and 48 hours. Three replicates were used per treatment. The pH, temperature and dissolved oxygen at the beginning and after 24 and 48hours from the test were measured. We estimated the CL50 through the Trimmed Spearman-Karber method. The blooms were constituted by Microcystis panniformis, M. aeruginosa, Anabaena circinalis, Cylindrospermopsis raciborskii and Planktothrix agardhii, producers of mycrocistin-LR confirmed with HPLC analysis. Samples of hepatotoxic blooms registered toxinogenic potential for C. silvestrii, with CL50-24h value of 47.48 mg.L-1 and CL5048h of 38.15 mg.L-1 for GARG samples in march/2005; CL50-24h of 113,13 mg.L-1 and CL5048h of 88,24 mg.L-1 for ARG July/2004; CL50-24h of 300.39 mg.L-1 and CL50-48h of 149.89 mg.L-1 for GARG October/2005. For cultured samples, values of CL50-24h and CL50-48h for C. raciborskii toxic strains were 228.05 and 120.28 mg.L-1, respectively. There was no mortality of C. silvestrii during the tests with non-toxic C. raciborskii strain. The toxicity test with C. silvestrii presented good sensitivity degree to cyanotoxins. The toxicity of natural hepatotoxic blooms samples (microcystins) and cultured neurotoxic saxitoxins producer samples analyzed in this study give us strong indications of that toxin s influence on the zooplanktonic community structure in tropical aquatic environments. Eleven cyanobacteria strains were isolated, representing 6 species: Anabaenopsis sp., Cylindrospermopsis raciborskii, Chroococcus sp., Microcystis panniformis, Geitlerinema unigranulatum e Planktothrix agardhii. None presented toxicity in Swiss mice. The strains were catalogued and deposited in the Laboratório de Ecologia e Toxicologia de Organismos Aquáticos (LETMA), in UFRN, and will be utilized in ecotoxicológical and ecophysiological studies, aiming to clarify the causes and control of cyanobacterial blooms in aquatic environments in RN. This state s reservoirs must receive broader attention from the authorities, considering the constant blooms occurring in waters used for human consumption
