Apreciação dos jogos por crianças e jovens em um festival de handebol

Nosso interesse pelo campo teórico da Praxiologia Motriz teve início no projeto de extensão universitária denominado “Ensinando e Aprendendo Handebol”, espaço no qual nos deparamos, já há quase 10 anos, com o desafio de ensinar handebol à crianças e jovens. Associados a este projeto de extensão, sentimos a necessidade de um grupo de pesquisa, no qual pudéssemos nos aprofundar nos estudos acerca da pedagogia dos esportes coletivos, surgindo, a partir do ano de 2009, o Núcleo de Estudos e Pesquisas das Abordagens Táticas dos Esportes Coletivos (NEPATEC).Departamento de Educación Físic

EEG-Based Epileptic Seizure Prediction Using Temporal Multi-Channel Transformers

Epilepsy is one of the most common neurological diseases, characterized by transient and unprovoked events called epileptic seizures. Electroencephalogram (EEG) is an auxiliary method used to perform both the diagnosis and the monitoring of epilepsy. Given the unexpected nature of an epileptic seizure, its prediction would improve patient care, optimizing the quality of life and the treatment of epilepsy. Predicting an epileptic seizure implies the identification of two distinct states of EEG in a patient with epilepsy: the preictal and the interictal. In this paper, we developed two deep learning models called Temporal Multi-Channel Transformer (TMC-T) and Vision Transformer (TMC-ViT), adaptations of Transformer-based architectures for multi-channel temporal signals. Moreover, we accessed the impact of choosing different preictal duration, since its length is not a consensus among experts, and also evaluated how the sample size benefits each model. Our models are compared with fully connected, convolutional, and recurrent networks. The algorithms were patient-specific trained and evaluated on raw EEG signals from the CHB-MIT database. Experimental results and statistical validation demonstrated that our TMC-ViT model surpassed the CNN architecture, state-of-the-art in seizure prediction.Comment: 15 pages, 10 figure

‘The smell of the place’: Managerialist culture in contemporary UK business schools

© 2014 Taylor & Francis. By introducing an intentionally provocative critique of managerialist regimes which typify contemporary UK business school culture, we argue that current business school management practices generate a climate of mistrust and alienation amongst academics. Such a climate is not conducive to a reformative agenda that business schools should be pursuing if they are to improve staff morale and the educational environment. Drawing on Ghoshal’s ‘smell of the place’ metaphor to structure this argument, we court deliberate irony and paradox. Rather than draw on heterodox theory to inform our critique we, instead, turn relatively mainstream management and organization theory against itself. Our argument is that even when examined through orthodox lenses, managerialist practices are found wanting and contradict the precepts of much mainstream normative theory

MicroRNA degradation by a conserved target RNA regulates animal behavior

International audiencemicroRNAs (miRNAs) repress target transcripts through partial complementarity. By contrast, highly complementary miRNA-binding sites within viral and artificially engineered transcripts induce miRNA degradation in vitro and in cell lines. Here, we show that a genome-encoded transcript harboring a near-perfect and deeply conserved miRNA-binding site for miR-29 controls zebrafish and mouse behavior. This transcript originated in basal vertebrates as a long noncoding RNA (lncRNA) and evolved to the protein-coding gene NREP in mammals, where the miR-29-binding site is located within the 3′ UTR. We show that the near-perfect miRNA site selectively triggers miR-29b destabilization through 3′ trimming and restricts its spatial expression in the cerebellum. Genetic disruption of the miR-29 site within mouse Nrep results in ectopic expression of cerebellar miR-29b and impaired coordination and motor learning. Thus, we demonstrate an endogenous target-RNA-directed miRNA degradation event and its requirement for animal behavio
