Investigating mathematical investigations

There are good reasons why we may involve the students in doing mathematics investigations. Recent curricula encourage this sort of activity but we notice that its application in the classroom is not a simple matter. We discuss the issues that arise when students are presented with investigative tasks, with special interest in the dynamics of the classroom and in the role of the teacher. Our aim is to derive suggestions for classroom practice as well as for further research and teacher development

Conforto térmico em instalações para processamento úmido de café

Este estudio tuvo como objetivo evaluar el confort térmico para trabajadores, en tres edificaciones de procesamiento húmedo de café en Colombia, utilizando el índice WBGT, y análisis de temperatura y humedad relativa a través de mapeo. Los límites recomendados del WBGT fueron excedidos en la actividad de abastecimiento de combustible de la secadora en la Edificación 3. Las tres edificaciones presentaron variabilidad higrotérmica espacial debida a la secadora de café, y a problemas con la ventilación, volumen de control y resistencia térmica de materiales en los edificios 2 y 3. Para favorecer la transferencia de calor de la secadora al ambiente exterior, y hacer más homogéneo el ambiente térmico de las edificaciones, se recomienda instalar puentes térmicos alrededor de esta zona, y para hacer más eficiente la evacuación de vapor y calor, aumentar el área de ventilación natural en las edificaciones 2 y 3, e instalar claraboyas de ventilación sobre la secadora

Innovation in open and distance continuing teacher education

Encontro realizado em Praga de 16-17 março de 2000In Portugal, since 1994 teachers from Basic and Secondary Education(1), in order to progress in their careers (according to the regulations of the Ministry of Education) need to engage themselves in continuing education. Courses or workshops on pedagogic, methodological or scientific topics are organized for them by higher education institutions, or by associations of schools of different levels located in a certain area. In these courses, teachers may gain credits, which are necessary for their progression. These are traditional face-to-face courses. Universidade Aberta offered this kind of courses too, but in 1997 it started an experimental programme of open and distance continuing education. Short courses on new technologies for teaching, evaluation and assessment techniques, didactics of literature, child and youth literature were offered to basic and secondary school teachers. This was the first open and continuing education programme organized by Universidade Aberta.info:eu-repo/semantics/publishedVersio

Abordagem clínica de intoxicações em canídeos por inseticidas anticolinesterásicos e utilização de testes imediatos (point of care)

Dissertação de Mestrado Integrado em Medicina VeterináriaPerante a suspeita de intoxicação aguda, a abordagem célere e sistemática ao doente, permite uma rápida prestação de cuidados específicos. A triagem, recolha da história clínica, avaliação e intervenção médica de urgência, o diagnóstico e a terapêutica são processos chave nessa abordagem. O diagnóstico, por norma, é suportado por um painel analítico inicial. O recurso a testes imediatos (“point of care”), permite avaliar não só a condição geral dos doentes em tempo real, mas também os efeitos que os xenobióticos possam ter a nível orgânico e que se traduzam, nomeadamente, em alterações do equilíbrio hidroeletrólitico e estado ácido base. O presente estudo pretendeu avaliar as alterações analíticas, detetadas através da ferramenta ePOC (“Enterprise Point of Care”), em animais suspeitos de intoxicação por inseticidas anticolinesterásicos e a sua eventual influência no diagnóstico e implementação da terapêutica. A amostra estudada consistiu em 14 canídeos, que na triagem médica apresentavam sintomas inespecíficos e outros compatíveis com intoxicação aguda por insecticidas anticolinesterásicos: tremores musculares (93%), hipersiália (64%), hipertermia (57%), cianose (50%), diarreia (57%) e vómito (36%). Foram colhidas amostras de sangue para a realização do teste ePOC e para ulterior análise toxicológica.Os resultados obtidos através do ePOC mostraram diminuição da pressão parcial de dióxido de carbono (pCO2) (64%), aumento da concentração de lactato (36%), aumento dos valores de hemoglobina e hematócrito (50%), hiperglicémia (36%) e aumento dos valores de creatinina (50%), não havendo, contudo, relação estatisticamente significativa entre as variáveis testadas e o diagnóstico toxicológico (p>0.05). Porém, em todos os animais considerados acidémicos houve detecção de compostos do grupo dos inseticidas anticolinesterásicos na análise toxicológica. O estudo clínico individualizado de cada caso permitiu verificar que, apesar da sintomatologia similar, os animais apresentavam distúrbios ácido-base diferentes, sendo por isso também necessária uma abordagem terapêutica diferenciada, fulcral especialmente em condições críticas. Estudos futuros, com uma amostra de maior dimensão e preferencialmente com exposição a diferentes xenobióticos, poderão permitir uma avaliação mais exata e abrangente da relação entre a etiologia das intoxicações e as alterações hidroeletrolíticas e de gases sanguíneas verificadas.ABSTRACT - Clinical Approach to Poisoning in Canidae by Anticholinesterase Insecticides and use of immediate tests (Point of Care) - Faced with a suspected acute intoxication, a prompt and systematic approach to the patient, allows a fast provision of specific care. The triage, history taking, assessment and emergency medical intervention, diagnosis and treatment are key processes in this approach. The diagnosis is usually supported by an initial analytic panel. The use of immediate testing ("point of care"), allows the evaluation, not only of the patient’s general condition in real time, but also the effects that xenobiotics may have at an organic level, which may result in electrolyte and acid base disorders. The presente study intended to evaluate the analytical changes detected by ePOC ("Enterprise Point of Care") in animals suspected of poisoning by anticholinesterase insecticides and their possible influence on the diagnostic and therapeutic implementation. The sample consisted of 14 canines, which had nonspecific symptoms and other compatible with acute poisoning by anticholinesterase insecticides: muscle tremors (93%), hypersialia (64%), fever (57%), cyanosis (50%), diarrhea (57%) and vomiting (36%). Blood samples were collect to perform ePOC testing and for further toxicological analysis. Analytical changes (ePOC) showed a decreased partial pressure of carbon dioxide (pCO2) (64%), an increased lactate concentration (36%), na increase in hemoglobin and hematocrit levels (50%), hyperglycemia (36%) and an increased serum creatinine values (50%), without, however, statistically significant relationship between the variables tested and toxicological diagnosis (p> 0.05). Nevertheless, in all animals considered acidemic, toxicological analysis showed the detection of anticholinesterase insecticides. The individualized clinical study of each case has shown, that despite the similar symptoms, the animals had different acid-base disorders and is, therefore, also required a different therapeutic approach, especially in critical conditions. Further studies with a larger sample and preferably with exposure to different xenobiotics may allow a more accurate and comprehensive evaluation of the relationship between the etiology of poisoning and blood gas and electrolyte changes observed

The state of the psychological contract and its relation to employees' psychological health

The present paper explores the role of the state of the psychological contract in predicting psychological health outcomes in a sample of 385 employees from different Spanish companies. Results indicate that the state of the psychological contract significantly predicts life satisfaction, work-family conflict and well-being beyond the predictive capacity of the content of the psychological contract. In addition, trust and fairness, two of the dimensions of the state of the psychological contract, jointly contribute to explaining these psychological health variables, adding value to the predictive role of fulfilment of the psychological contract. These results lend support to the approach proposed by Guest and colleagues.El presente trabajo estudia el papel del estado del contrato psicológico para predecir resultados de salud psicológica en una muestra de 385 empleados de distintas empresas españolas. Los resultados indican que el estado del contrato psicológico predice la satisfacción con la vida, el conflicto trabajo-familia y el bienestar psicológico más allá de la predicción alcanzada por el propio contenido del contrato psicológico, y que la confianza y la justicia, dos de las dimensiones del estado del contrato psicológico, consideradas conjuntamente contribuyen a explicar dichas variables añadiendo valor al rol que como predictor desempeña el cumplimiento del contrato. Estos resultados suponen un apoyo a los planteamientos de Guest y colaboradores

Addressing the patient experience in myocardial perfusion scintigraphy

Background: Myocardial Perfusion Scintigraphy is a medical exam whose purpose is to evaluate myocardial perfusion. This examination due to their procedures can generate some anxiety in patients that can disturb the good performance of the exam. The main objective of this study is to perform an analysis of patient's undergoing myocardial perfusion scintigraphy experience, assess patient`s anxiety and check Nuclear Medicine Department communication and information effectiveness. Material and methods: For this study, the State-Trait Anxiety Inventory (STAI) and two Scan Experience Questionnaires were used. Sixty patients answered the questionnaires before and after myocardial perfusion scintigraphy. Results: Patients reported medium levels of scan-related anxiety and trait anxiety before the myocardial perfusion scintigraphy. After the scan, there is a slight decrease in patients' anxiety. Results of the scan, radiation used, duration of the scan and the injection of the radiopharmaceutical are the most relevant patients' concerns before the scan. 15% of the sample did not receive the necessary information or the most effective way. Conclusions: The results suggest that there are several factors that tend to trigger the patient's experience and anxiety. Strategies to improve patient myocardial perfusion scintigraphy experience at Nuclear Medicine Department are presented.info:eu-repo/semantics/publishedVersio
