Aulas virtuais: uma discussão sobre a interação no aprendizado de língua estran...

Este artigo fornece um retorno sobre a rápida transição dos cursos presenciais para a modalidade remota no contexto da pandemia Covid-19, que afetou o mundo inteiro desde março de 2020. Revelando nossa experiência como jovens professores de francês, inseridos em projetos de extensão na Universidade Federal Fluminense (UFF), abordaremos os desafios de implantação de atividades interativas no contexto de cursos m...

Targeting the uncertainty of predictions at patient-level using an ensemble of ...

Despite being able to make accurate predictions, most existing prognostic models lack a proper indication about the uncertainty of each prediction, that is, the risk of prediction error for individual patients. This hampers their translation to primary care settings through decision support systems. To address this problem, we studied different methods for transforming classifiers into probabilistic/confidence-...

Neuropsychological predictors of conversion from mild cognitive impairment to A...

Background: Predicting progression from Mild Cognitive Impairment (MCI) to Alzheimer's Disease (AD) is an utmost open issue in AD-related research. Neuropsychological assessment has proven to be useful in identifying MCI patients who are likely to convert to dementia. However, the large battery of neuropsychological tests (NPTs) performed in clinical practice and the limited number of training examples are chal...

Background Predicting progression from Mild Cognitive Impairment (MCI) to Alzheimer’s Disease (AD) is an utmost open issue in AD-related research. Neuropsychological assessment has proven to be useful in identifying MCI patients who are likely to convert to dementia. However, the large battery of neuropsychological tests (NPTs) performed in clinical practice and the limited number of training examples are chall...

Predicting progression of mild cognitive impairment to dementia using neuropsyc...

Background: Predicting progression from a stage of Mild Cognitive Impairment to dementia is a major pursuit in current research. It is broadly accepted that cognition declines with a continuum between MCI and dementia. As such, cohorts of MCI patients are usually heterogeneous, containing patients at different stages of the neurodegenerative process. This hampers the prognostic task. Nevertheless, when learning...

Classification of primary progressive aphasia: do unsupervised data mining meth...

Our objective was to test whether data mining techniques, through an unsupervised learning approach, support the three-group diagnostic model of primary progressive aphasia (PPA) versus the existence of two main/classic groups. A series of 155 PPA patients observed in a clinical setting and subjected to at least one neuropsychological/language assessment was studied. Several demographic, clinical and neuropsych...

Caracterização do perfil lesional na ginástica acrobática

Este estudo teve como propósito analisar as lesões ocorridas ao longo da época desportiva 2012/2013, em todos os ginastas portugueses do distrito do Porto dos vários escalões e, simultaneamente caracteriza-los a nível antropométrico e maturacional. A amostra foi constituída por 33 atletas de Ginástica Acrobática, com idades entre os 8 e 23 anos, treinando em média 14,79h/semana. Nestas ginastas foram avaliadas ...
