The Symmetry Concept in the Perspective of Basic Education Teachers

The curricular changes that have occurred with the Portuguese Mathematics programme of study of 2007 showed, among other situations, the introduction of new contents and the new concept of symmetry. For the teachers, these changes require scientific updates to be provided so that the outcomes of the mathematics teaching can be guaranteed. In the academic year 2011/2012 a questionnaire was applied to a 142 inservice basic education teachers of a particular region of Portugal, to analyze the content knowledge in this subject (symmetry) and the form of scientific update occurred. The processing of data allowed us to identify inadequate conceptions, beliefs, topics more or less successful in responses and also compare the teacher’s responses of the different teaching groups.info:eu-repo/semantics/publishedVersio

A influência de variáveis ambientais no crescimento de espécies/procedências de Eucalyptus spp. nos estados de Minas Gerais e Espírito Santo.

Foram analisados onze experimentos de introdução de espécies e procedências potenciais de Eucalyptus instalados em várias localidades dos estados de Minas Gerais e Espírito Santo. O estudo da influência de variáveis ambientais dos locais de introdução no crescimento em altura dessas espécies, aos três anos e meio de idade, permitiu concluir que a altitude do local do experimento foi a variável que mais influenciou o crescimento em altura de Eucalyptus camaldulensis, E. dunnii, E. grandis, E. pellita e E. tereticornis; o déficit hídrico isoladamente influenciou significativamente apenas o crescimento em altura de E. urophylla; a temperatura média e o total anual de precipitações não influenciaram isoladamente o crescimento em altura das oito espécies estudadas, e que é possível prever o comportamento das espécies e procedências em relação ao crescimento em altura, conhecendo-se a altitude, déficit hídrico e total anual médio de precipitações do local de introdução

Occupational stress and cognitive appraisal profiles as predictors of students’ burnout

Objective: Analyze if different patterns of occupational stress experienced by students (lower versus higher) and different cognitive appraisal profiles assumed by students (positive evaluation of academic activity versus negative evaluation of academic activity) affect their experience of burnout over time. Background: The interactive and transactional perspective of adaptation to stress was adopted to analyze how university students evaluate their activity and related academic stress, and how they feel in terms of burnout. Method: Longitudinal study design, with three moments of data collection, with a sample of 175 psychology students, from a Portuguese university. The investigation protocol included the Stress Questionnaire for Students, the Primary and Secondary Cognitive Appraisal Scale, and the Shirom-Melamed Burnout Scale. Results: The results showed that students who experienced higher levels of stress and a negative evaluation of their academic activity also reported higher levels of burnout when compared to students who experienced lower levels of stress and positive evaluation of academic activity. Moreover, a pattern of high stress in M1 increases in 443% the probability to experience moderate to high burnout in M2. A profile of negative evaluation of the academic activity in M1 increases in 594% the probability to experience high burnout in M2. Students exposed to high levels of burnout at M2 are over nine times more likely to experience moderate levels of burnout at M3, and over 300 times more likely to experience high levels of burnout at M3. Conclusion: Students who experience higher academic stress and those who evaluate their academic activity more negatively have a higher tendency to experience burnout. Although, the experience of burnout in a specific data point is the main predictor of experiencing burnout in a later moment, highlighting the chronic effects of this syndrome on human wellbeing. Application: This study provides specific indications of how much stress and cognitive appraisal can affect burnout, alerting also for the chronic nature of burnout feelings, which must be considered in safety and occupational health interventions.This study was conducted at the Psychology Research Centre (CIPsi/UM) School of Psychology, University of Minho, supported by the Foundation for Science and Technology (FCT) through the Portuguese State Budget (UIDB/01662/2020)

Health-related quality of life in portuguese SLE patients: an outcome measure independent of disease activity and cumulative damage

PURPOSE: To evaluate quality of life in Portuguese patients with Systemic Lupus Erithematosus (SLE) and its correlation with disease activity and cumulative damage. METHODS: We included consecutive SLE patients, fulfilling the 1997 ACR Classification Criteria for SLE and followed at the Rheumatology Department of the University Hospital of Coimbra, Portugal at time of visit to the outpatient clinic. Quality of life was evaluated using the patient self-assessment questionnaire Medical Outcomes Survey Short Form-36 (SF-36) (validated Portuguese version). The consulting rheumatologist fulfilled the SLE associated indexes for cumulative damage (Systemic Lupus International Collaborating Clinics- Damage Index: SLICC/ACR-DI) and disease activity (Systemic Lupus Erythematosus Disease Activity Index: SLEDAI 2000). Correlation between SLEDAI and SLICC and SF-36 was tested with the Spearman Coefficient. Significant level considered was 0.05. RESULTS: The study included 133 SLE patients (90.2% female, mean age - 40.7 years, mean disease duration - 8.7 years). Most patients presented low disease activity (mean SLEDAI = 4.23) and limited cumulative damage (mean SLICC = 0.76). Despite that, SF-36 mean scores were below 70% in all eight domains of the index. Physical function domains showed lower scores than mental function domains. The QoL in this group of patients is significantly impaired when compared with the reference Portuguese population (p<0.05 in all domains). There was no correlation between clinical activity or cumulative damage and quality of life. CONCLUSION: QoL is significantly compromised in this group of SLE patients, but not related with disease activity or damage. These findings suggest that disease activity, cumulative damage and QoL are independent outcome measures and should all be used to assess the full impact of disease in SLE patients

Análise estatística de um sistema agroflorestal através do índice de produção equivalente.

As interações biológicas, econômicas e ambientais que ocorrem entre as culturas componentes de um sistema agroflorestal) (SAF, implicam em respostas diferenciadas das respectivas culturas, conforme os arranjos aos quais as mesmas estejam submetidas. Num ensaio de avaliação de S SAF' , cada parcela apresenta mais de uma variável a ser estudada e portanto, os dados apresentam-se de forma multidimensional. Assim sedo, a forma mais apropriada para análise desses sistemas é através do uso das técnicas da estatísticas multivariadas. Não obstante, o tipo de analise estatística mais freqüentemente realizado nos sistemas consorciados é através da transformação do problema multivariado em um problema univariado através da obtenção de uma única variável como função resposta das observações das culturas componentes e, a partir da mesma, aplicam-se os testes estatísticos comumente empregados na análise de dados agronômicos

Rash, fever and proteinuria after amoxicillin in a SLE patient

We report a case of severe type IV hypersensitivity reaction to amoxicillin, which occurred in a person with a 12-year history of SLE. The present case illustrates the wide differential diagnosis in a SLE patient who presents with an allergic drug reaction. The attribution of the presenting symptoms to the underlying SLE and/or to the drugs used to treat SLE and coexisting conditions is a major challenge

Análise de um sistema agroflorestal usando estatística multivariada.

Os cultivos consorciados onde são cultivados no mesmo espaço, de forma simultânea ou seqüencial, culturas anuais e/ou fruteiras com espécies florestais, com a presença ou não de animais, receberam a denominação específica de sistemas agroflorestais, ou simplesmente, s SAF' . Nas regiões tropicais, parece óbvio as vantagens desses sistemas em relação às outras formas de cultivo, principalmente no que tange a sua sustentabilidade a longo prazo. Não obstante, as análises quantitativas dos efeitos diretos das culturas componentes dos s SAF' , bem como das associações existentes entre essas culturas, são fundamentais para uma melhor compreensão e sistematização desses sistemas de cultivo. Entre os componentes dos s SAF' , há interações biológicas, econômicas e ambientais, entre outras, o que torna complexo as análises e interpretações dos mesmos
