    Obesity is a currently a major problem plaguing the world as a whole. The International Obese Task Force (IOTF) estimates at least 1.1 billion adults are overweight with some 312 million of those obese, globally. 1 As of 2004, in less than twenty years, the prevalence of obesity had more than doubled in adults with childhood obesity prevalence rising even more rapidly. Obesity, however, can be classified as a disease of its own or as a symptom of another disease. Two such diseases that have obesity as a symptom are Metabolic Syndrome and Cushing ’s syndrome. Metabolic Syndrome is a condition that is represented by the presence of multiple risk factors. These factors, as indicated by The National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III), include elevated waist circumference, elevated triglycerides, reduced high-density lipoprotein cholesterol (HDL-C), elevated blood pressure and elevated fasting glucose. Table 1 provides the modified categorical cut-off points for the five Metabolic Syndrome diagnostic criteria with the modifications including medical treatment received for diabetes, hypertension or elevated triglycerides

    A Unified Cognitive Model of Visual Filling-In Based on an Emergic Network Architecture

    The Emergic Cognitive Model (ECM) is a unified computational model of visual filling-in based on the Emergic Network architecture. The Emergic Network was designed to help realize systems undergoing continuous change. In this thesis, eight different filling-in phenomena are demonstrated under a regime of continuous eye movement (and under static eye conditions as well). ECM indirectly demonstrates the power of unification inherent with Emergic Networks when cognition is decomposed according to finer-grained functions supporting change. These can interact to raise additional emergent behaviours via cognitive re-use, hence the Emergic prefix throughout. Nevertheless, the model is robust and parameter free. Differential re-use occurs in the nature of model interaction with a particular testing paradigm. ECM has a novel decomposition due to the requirements of handling motion and of supporting unified modelling via finer functional grains. The breadth of phenomenal behaviour covered is largely to lend credence to our novel decomposition. The Emergic Network architecture is a hybrid between classical connectionism and classical computationalism that facilitates the construction of unified cognitive models. It helps cutting up of functionalism into finer-grains distributed over space (by harnessing massive recurrence) and over time (by harnessing continuous change), yet simplifies by using standard computer code to focus on the interaction of information flows. Thus while the structure of the network looks neurocentric, the dynamics are best understood in flowcentric terms. Surprisingly, dynamic system analysis (as usually understood) is not involved. An Emergic Network is engineered much like straightforward software or hardware systems that deal with continuously varying inputs. Ultimately, this thesis addresses the problem of reduction and induction over complex systems, and the Emergic Network architecture is merely a tool to assist in this epistemic endeavour. ECM is strictly a sensory model and apart from perception, yet it is informed by phenomenology. It addresses the attribution problem of how much of a phenomenon is best explained at a sensory level of analysis, rather than at a perceptual one. As the causal information flows are stable under eye movement, we hypothesize that they are the locus of consciousness, howsoever it is ultimately realized

The definitive version was published in Journal of Invertebrate Pathology 111 (2012): 90-93, doi:10.1016/j.jip.2012.06.002.Degenerative lesions in the dorsum of the horseshoe crab (Limulus polyphemus) exoskeleton, eyes, arthrodial membrane, and base of the telson were documented in a population of wild caught laboratory animals. The disease can lead to loss of tissue structure and function, deformed shells, abnormal molting, loss of ocular structures, erosion of interskeletal membranes, and cardiac hemorrhage. Microscopy, histopathology, and in vitro culture confirmed the causative agent to be a green algae of the family Ulvaceae. Further research may explain how green algae overcome horseshoe crab innate immunity leading to external and internal damage.This study was supported in part by the Frederick B. Bang Fellowship and a grant from the Division of Research Resources, National Institutes of Health (P-40-RR1333-07)

    A aprendizagem das ciências baseada na resolução de problemas online : comparação entre estilos de aprendizagem e opiniões de alunos do 7º ano

    Publicado em "Atas do XII Congresso Internacional Galego-Português de Psicopedagogia. Braga : Universidade do Minho, 2013. ISBN : 978-989-8525-22-2"A Aprendizagem Baseada na Resolução de Problemas online (ABRP online) é uma abordagem de ensino em que os alunos aprendem através da resolução de problemas, em grupo e com recurso exclusivo à Internet. Diferentes alunos apresentam diferentes preferências em termos da forma como gostam de aprender, ou seja, apresentam diferentes estilos de aprendizagem. Alguns desses estilos são mais compatíveis com determinados tipos de abordagens de ensino do que outros e dependendo essa compatibilidade, entre outros, do nível de autonomia que estas abordagens requerem. Assim, o objetivo deste estudo é analisar a opinião de alunos do 7º ano de escolaridade sobre o ensino do tema Dinâmica da Terra através da ABRP online (que requer elevada autonomia) em função do estilo de aprendizagem. Para o efeito, utilizou-se um questionário de opinião e um teste de estilos cognitivos. Os resultados deste estudo sugerem que os alunos com preferência pelo menos alta pelos estilos reflexivo, pragmático ou teórico aderiram um pouco mais à ABRP online do que os que têm um estilo ativo. Estes resultados devem ser aprofundados através de outras técnicas de recolha de dados a fim de poderem ajudar os professores a adequar o ensino orientado para a ABRP às preferências de aprendizagem dos seus alunos
