Relatório de ensino supervisionada, realizada no agrupamento vertical n.º 3 de Évora - Santa Clara e Escola Secundária Severim de Faria em ensino de educação física nos ensinos básico e secundário

O presente relatório tem como objectivo efectuar uma retrospectiva e um balanço sobre todo o trabalho desenvolvido ao longo do ano lectivo na Prática de Ensino Supervisionada (PES). A prestação do aluno de PES foi ao longo deste relatório analisada minuciosamente, sendo na sua análise implícita uma reflexão crítica de carácter importante. A PES desenvolveu-se na EB 2;3 de Santa Clara, EB1 de São Mamede e na Escola Secundária de Severim Faria. Concluiu-se que o planeamento é essencial para que exista uma organização e controlo sobre o processo ensino­ aprendizagem; que a avaliação formativa é essencial para o sucesso dos alunos; o planeamento por etapas assume-se como o mais adequado para o processo ensino­aprendizagem. Por último considera-se que leccionar uma aula é muito mais que colocar os alunos a realizar uma modalidade desportiva, sendo necessário, pensar, planear, organizar, demonstrar, acompanhar, facultar informação e adaptar-se aos alunos e ao meio escolar. ABSTRACT; The present report aims to make a retrospective overview of the work throughout the school year in Supervised Practice Teaching (SPT). The present report aims to make a retrospective overview of the work throughout the school year in Supervised Practice Teaching (SPT). The work of the student of SPT is carefully examined through this report; a critical reflexion is implicit in all chapters. The SPT was developed in three schools: EB 2, 3, Santa Clara, EB1 São Mamede and Secondary School Severim Faria. lt was concluded that planning is essential for achieving a high level of organization and control on the teaching-learning process; that the formative evaluation is fundamental for the student’s success; and that a planning model based on stages seem to be the most appropriate for the learning process. Also, it was understood that teaching a lesson is much more than getting the students practicing a sport; it requires skills like planning, organizing, demonstrating, instructing and adapting to the students and school’s characteristics.

Relatório de prática de ensino supervisionada realizado no agrupamento vertical n.º 3 de Évora - Santa Clara e Escola Secundária Severim de Faria em educação física nos ensinos básico e secundário

O objectivo deste relatório é efectuar uma reflexão fundamentada sobre a prática pedagógica desenvolvida ao longo do ano lectivo 2009/201O. A dimensão investigativa está presente ao longo de todo o relatório e encontra-se associada à reflexão sobre o trabalho desenvolvido nas instituições escolares em que estive inserido. No decorrer deste relatório são destacas as seguintes temáticas: modelos de planeamento; ensino das actividades físico-desportivas; destrezas do professor; promoção da saúde; avaliação; participação na escola; desenvolvimento profissional. Conclusões: O Modelo de planeamento por etapas é aquele que mais favorece a aprendizagem dos alunos. No ensino dos jogos desportivos colectivos, o modelo teaching games for understanding assume-se como uma alternativa às abordagens tradicionais centradas na técnica. Informação aumentada dirigida para um foco externo parece dar origem a uma melhor aprendizagem. As aulas de Educação Física não estão a conseguir dar o contributo necessário para a obtenção dos níveis recomendados de actividade física. ABSTRACT: The purpose of this report is to conduct a reasoned discussion about the pedagogical practice developed during the academic year 2009/201O. The investigative dimension is present throughout the report and is linked to the reflection on the work that was undertaken in schools. Throughout this report the following topics are highlighted: planning models, teaching physical and sporting activities, teacher's skills, health promotion, evaluation, participation in school, and professional development. Conclusions: The model of "planning steps" is one most conducive to student learning. ln collective sports games, the teaching games for understanding model is assumed as an alternative to traditional approaches focused on the critical components of each motor skill. The use of an externa! focus of attention appears to lead to better learning. lt seems that Physical Education classes are failing to provide the levels of physical activity recommended for young people.

Contextualizing the tensions and weaknesses of information privacy and data breach notification laws

Data breach notification laws have detailed numerous failures relating to the protection of personal information that have blighted both corporate and governmental institutions. There are obvious parallels between data breach notification and information privacy law as they both involve the protection of personal information. However, a closer examination of both laws reveals conceptual differences that give rise to vertical tensions between each law and shared horizontal weaknesses within both laws. Tensions emanate from conflicting approaches to the implementation of information privacy law that results in different regimes and the implementation of different types of protections. Shared weaknesses arise from an overt focus on specified types of personal information which results in ‘one size fits all’ legal remedies. The author contends that a greater contextual approach which promotes the importance of social context is required and highlights the effect that contextualization could have on both laws.

Advances in skin cancer early detection and diagnosis

OBJECTIVES: To provide an overview of 1) traditional methods of skin cancer early detection, 2) current technologies for skin cancer detection, and 3) evolving practice models of early detection. DATA SOURCES: Peer-reviewed databased articles and reviews, scholarly texts, and Web-based resources. CONCLUSION: Early detection of skin cancer through established methods or newer technologies is critical for reducing both skin cancer mortality and the overall skin cancer burden. IMPLICATIONS FOR NURSING PRACTICE: A basic knowledge of recommended skin examination guidelines and risk factors for skin cancer, traditional methods to further examine lesions that are suspicious for skin cancer and evolving detection technologies can guide patient education and skin inspection decisions.

Dielectric performance of polymer nanocomposites synthesized by atmospheric-pressure plasma-treated silica nanoparticles

In this study, atmospheric-pressure plasmas were applied to modify the surface of silane-coated silica nanoparticles. Subsequently nanocomposites were synthesized by incorporating plasma-treated nanoparticles into an epoxy resin matrix. Electrical testing showed that such novel dielectric materials obtained high partial discharge resistance, high dielectric breakdown strength, and enhanced endurance under highly stressed electric field. Through spectroscopic and microscopic analysis, we found surface groups of nanoparticles were activated and radicals were created after the plasma treatment. Moreover, a uniform dispersion of nanoparticles in nanocomposites was observed. It was expected that the improved dielectric performance of the nanocomposites can attribute to stronger chemical bonds formed between surface groups of plasma-treated nanoparticles and molecules in the matrix. This simple yet effective and environmentally friendly approach aims to synthesize the next generation of high-performance nanocomposite dielectric insulation materials for applications in high-voltage power systems.

The Games Concept Approach (GCA) as a mandated practice : views of Singaporean teachers

This paper reports on the views of Singaporean teachers of a mandated curriculum innovation aimed at changing the nature of games pedagogy within the physical education curriculum framework in Singapore. Since its first appearance over 20 years ago, Teaching Games for Understanding (TGfU), as an approach to games pedagogy has gathered support around the world. Through a process of evolution TGfU now has many guises and one of the latest of these is the Games Concept Approach (GCA) a name given to this pedagogical approach in Singapore. As part of a major national curricular reform project the GCA was identified as the preferred method of games teaching and as a result was mandated as required professional practice within physical education teaching. To prepare teachers for the implementation phase, a training program was developed by the National Institute of Education in conjunction with the Ministry of Education and well known experts in the field from the United States. For this part of the study, 22 teachers from across Singapore were interviewed. The data were used to create three fictional narratives, a process described by Sparkes (2002a) and used more recently by Ryan (2005) in the field of literacy. The stories were framed using Foucault’s (1980/1977) notion of governmentality and Bernstein’s (1996) notion of regulative discourse. The narratives reveal tales of confusion, frustration but also of hope and enthusiasm.

Assessment and application of clustering techniques to atmospheric particle number size distribution for the purpose of source apportionment

Long-term measurements of particle number size distribution (PNSD) produce a very large number of observations and their analysis requires an efficient approach in order to produce results in the least possible time and with maximum accuracy. Clustering techniques are a family of sophisticated methods which have been recently employed to analyse PNSD data, however, very little information is available comparing the performance of different clustering techniques on PNSD data. This study aims to apply several clustering techniques (i.e. K-means, PAM, CLARA and SOM) to PNSD data, in order to identify and apply the optimum technique to PNSD data measured at 25 sites across Brisbane, Australia. A new method, based on the Generalised Additive Model (GAM) with a basis of penalised B-splines, was proposed to parameterise the PNSD data and the temporal weight of each cluster was also estimated using the GAM. In addition, each cluster was associated with its possible source based on the results of this parameterisation, together with the characteristics of each cluster. The performances of four clustering techniques were compared using the Dunn index and Silhouette width validation values and the K-means technique was found to have the highest performance, with five clusters being the optimum. Therefore, five clusters were found within the data using the K-means technique. The diurnal occurrence of each cluster was used together with other air quality parameters, temporal trends and the physical properties of each cluster, in order to attribute each cluster to its source and origin. The five clusters were attributed to three major sources and origins, including regional background particles, photochemically induced nucleated particles and vehicle generated particles. Overall, clustering was found to be an effective technique for attributing each particle size spectra to its source and the GAM was suitable to parameterise the PNSD data. These two techniques can help researchers immensely in analysing PNSD data for characterisation and source apportionment purposes.

Novel loci affecting iron homeostasis and their effects in individuals at risk for hemochromatosis

Variation in body iron is associated with or causes diseases, including anaemia and iron overload. Here, we analyse genetic association data on biochemical markers of iron status from 11 European-population studies, with replication in eight additional cohorts (total up to 48,972 subjects). We find 11 genome-wide-significant (P<5 × 10−8) loci, some including known iron-related genes (​HFE, ​SLC40A1, ​TF, ​TFR2, ​TFRC, ​TMPRSS6) and others novel (​ABO, ​ARNTL, ​FADS2, ​NAT2, ​TEX14). SNPs at ​ARNTL, ​TF, and ​TFR2 affect iron markers in ​HFE C282Y homozygotes at risk for hemochromatosis. There is substantial overlap between our iron loci and loci affecting erythrocyte and lipid phenotypes. These results will facilitate investigation of the roles of iron in disease.
