A chain-interactive innovation model for the learning economy: Prelude for a proposal

The implementation of innovation has a central role in the dynamic knowledge economy of the twenty-first century. The ability to assemble new expertise and commercialise new business propositions constitutes one of the central characteristics in today’s globalising, learning-intensive, fast changing economic life. This paper sets out to articulate a stylised understanding of the modern innovation process on the basis of the currently available understanding in the innovation studies tradition. The conceptual model seeks to capture the essential features of organisations engaged in developing dynamic factors of competitiveness.innovation; innovation process; conceptual model

Generating time series reference models based on event analysis

Creating a reference model that represents a given set of time series is a relevant problem as it can be applied to a wide range of tasks like diagnosis, decision support, fraud detection, etc. In some domains, like seismography or medicine, the relevant information contained in the time series is concentrated in short periods of time called events. In this paper, we propose a technique for generating time series reference models based on the analysis of the events they contain. The proposed technique has been applied to time series from two medical domains: Electroencephalography, a neurological procedure to record the electrical activity produced by the brain and Stabilometry, a branch of medicine studying balance-related functions in human beings

Two Different Approaches of Feature Extraction for Classifying the EEG Signals

The electroencephalograph (EEG) signal is one of the most widely used signals in the biomedicine field due to its rich information about human tasks. This research study describes a new approach based on i) build reference models from a set of time series, based on the analysis of the events that they contain, is suitable for domains where the relevant information is concentrated in specific regions of the time series, known as events. In order to deal with events, each event is characterized by a set of attributes. ii) Discrete wavelet transform to the EEG data in order to extract temporal information in the form of changes in the frequency domain over time- that is they are able to extract non-stationary signals embedded in the noisy background of the human brain. The performance of the model was evaluated in terms of training performance and classification accuracies and the results confirmed that the proposed scheme has potential in classifying the EEG signals

Modelling Stabilometric Time Series

Stabilometry is a branch of medicine that studies balance-related human functions. Stabilometric systems generate time series. The analysis of these time series using data mining techniques can be very useful for domain experts. In the field of stabilometry, as in many other domains, the key nuggets of information in a time series are concentrated within definite time periods known as events. In this paper, we propose a technique for creating reference models for stabilometric time series based on event analysis. After testing the technique on time series recorded by top-competition sportspeople, we conclude that stabilometric models can be used to classify individuals by their balance-related abilitie

Os mercados, os seus saberes e as suas incertezas

A globalização, tal qual a conhecemos, não resolve os problemas, nem equaciona as questões, do viver em conjunto sobre a Terra. No contexto actual, a luta pela democracia assume, assim, três vectores essenciais: a reinvenção do poder emancipador do conhecimento, com mais e melhores ciências, ciências sociais e outros saberes argumentativos; a reintrodução da escola como o local privilegiado da aprendizagem para a cidadania plena; a instalação e defesa de uma sociedade do reconhecimento, em que a valorização do outro como interlocutor corresponda ao pulsar planetário da nossa espécie.Such as we know it, globalization does not solve the problems or address the questions of living together on the Earth. Thus, in the current context, the struggle for democracy involves three essential aspects: the reinvention of the emancipatory power of knowledge, with more and better sciences, social sciences, and other argumentative knowledges; the reintroduction of the school as the privileged site for the learning of a full citizenship; and the establishment and defense of a society of recognition, in which the valorization of the other as interlocutor corresponds to the planetary throbbing of our species.La globalisation, telle que nous la connaissons, ne résout pas les problèmes, ni met en rapport les questions, de vivre ensemble sur la planète. Dans le contexte actuel, la lutte pour la démocratie assume ainsi trois vecteurs essentiels: la réinvention du pouvoir émancipateur de la connaissance, grâce à plus de sciences et de meilleures sciences, sciences sociales et d’autres savoirs argumentatifs; la réintroduction de l’école comme lieu privilégié de l’apprentissage pour la pleine citoyenneté; l’instauration et la défense d’une société de reconnaissance, dans laquelle la valorisation de l’autre en tant qu’interlocuteur corresponde à la pulsation planétaire de notre espèce

Natural variability of lotic Mediterranean ecosystems or wildfire perturbations: who will win?

This study evaluates the impacts of wildfires in lotic Mediterranean ecosystems. It was carried out at Monchique ridge after big wildfires occurred during 2002 and 2003. Deferential impacts were evaluated comparing historical results obtained before the wildfires (1999 and 2001), with the post fire ones (2006 and 2007). Physical and chemical parameters of the water, habitat morphology, diatoms, macrophytes, macroinvertebrates and fishes were evaluated at 10 collecting places, before and after wildfires. High recovering rates were observed to the vegetation, but it is still possible to found fire impacts over macrophytes and river morphology. Wildfires, contributed to canopy decrease and, consequently to the growth of plants that usually are controlled by shadow. As a result, vegetation biodiversity tend to increase. River banks tend also to be invaded by terrestrial plants. Higher post fires recover rates were observed to the more aquatic communities (diatoms, macroinvertebrates and fishes). For those communities, comparing spring situations before and after the fires no substantial differences were observed. Sometimes differences between consecutive years are even higher. So it can be concluded that magnitude of wildfire impacts is less than the natural inter-annual variability of Mediterranean rivers. Long-term effects of forest fires, resulting from large woody debries, were also detected by morphological alterations, like debries dams. Habitat diversity increase and impacts on aquatic communities are expected

Insatisfação corporal e transtornos alimentares em adolescentes de Palmas (TO)

To identify the prevalence of risk behaviors to eating disorders in teenagers from Palmas-TO and its relation to body dissatisfaction and sociodemographic characteristics. It’s a quantitative descriptive research performed with student teenagers from high school. The data collect happened remote. The Eating Attitudes Test (EAT-26) was used for eating behavior evaluation and the Body Shape Questionnaire (BSQ) to evaluate body self-realization. The sample was constituted by 58 participants, majorly females with ages between 15 and 17 years, studying in second year. We found that 17,2% of the sample had a positive score on EAT-26, while 8,6% showed some level of body dissatisfaction according to BSQ. There were no associations between sex, age, height and BMI with the scores on EAT-26 and BSQ. A positive association between body dissatisfaction and overweight or obesity was observed (p=0,007). Furthermore, it was found that adolescents with some level of body dissatisfaction had higher median score on EAT-26 (p=0,03).Identificar a prevalência de comportamentos de risco para transtornos alimentares em adolescentes de Palmas-TO e sua associação com a insatisfação corporal e características sociodemográficas. Trata-se de uma pesquisa quantitativa descritiva realizada com adolescentes estudantes do ensino médio (EM). A coleta de dados se deu de forma remota. Foi utilizado o Eating Attitudes Test (EAT-26) para avaliar comportamento alimentar e o Body Shape Questionnaire (BSQ) para avaliar a autopercepção corporal. A análise dos dados foi realizada com o teste de Mann-Whitney. A amostra foi constituída por 58 participantes, em sua maioria do sexo feminino com idade entre 15 e 17 anos, cursando o 2º ano do EM. Encontrou-se que 17,2% da amostra obteve pontuação positiva no EAT-26, enquanto 8,6% apresentaram algum grau de insatisfação corporal segundo o BSQ. Não houveram associações entre sexo, idade e IMC com as pontuações no EAT-26 e BSQ. Foi observada associação positiva entre insatisfação corporal e sobrepeso ou obesidade (p=0,007). Ademais, encontrou-se que adolescentes com algum grau de insatisfação corporal possuem maior mediana de pontuação no EAT-26 (p=0,03). A elevada insatisfação corporal na adolescência predispõe comportamentos alimentares inadequados, sendo que tanto adolescentes do sexo feminino como com excesso de peso possuem maior chance de estarem insatisfeitos com seu corpo
