La enseñanza de la bioética personalista promueve cambios en las actitudes de los alumnos adolescentes de la escuela pública

En este artículo se relata una experiencia de la enseñanza de la Bioética personalista aplicada a estudiantes de segundo año del nivel secundario de dos escuelas públicas ubicadas en una ciudad del interior de Río Grande do Sul, Brasil. Con el objetivo de evaluar la receptividad de la Bioética personalista se aplicó un cuestionario antes y después de dar charlas a un total de 194 alumnos de ambos sexos, entre 15 y 17 años. Se realizó un análisis estadístico comparativo de los resultados. Se evidenció la coincidencia de los alumnos en el pensar ontológico personalista, salvo en el área de la dignidad humana y la sexualidad. Los mejores resultados se obtuvieron en la escuela donde los profesores acompañaron el proceso. Se constató la necesidad de incentivar la capacidad crítica de los jóvenes para que aprendan a discernir los mecanismos de manipulación e imposición de determinadas ideologías. En este sentido, la formación de los educadores resultó ser muy necesaria y urgente para que los alumnos obtengan apoyo efectivo.

Colchester Institute: Virtual bricklaying lays the foundations for the future

Brickwork Lecturer Chris Holland has created a resource that allows students to lay bricks on a computer screen. The former bricklayer has used the ActivInspire suite on the Promethean interactive whiteboard to draw various types of bricks, as well as other interactive tools from the building site. Students are now more engaged in the classroom as they can practise cavity walling, block work, and setting walls on foundation before they get out in the workplace. Learners using the resource range from 14–16-year-old school students and full-time 16–19-year-olds completing Diplomas in brickwork to apprentices completing NVQs.

Violência familiar na infância: fator de risco para o excesso de peso em adolescentes ?

O excesso de peso tem sido cada vez mais reconhecido como um importante problema de saúde entre os adolescentes. Para identificar seus fatores de risco, recentemente, alguns pesquisadores têm incorporando fatores psicossociais em modelos explicativos, incluindo a violência familiar na infância. No entanto, a questão ainda é pouco explorada na literatura, sendo este o primeiro estudo nacional sobre o assunto. O objetivo deste estudo foi avaliar se a violência na infância é um fator de risco para o excesso de peso na adolescência. Para isso, foi realizado, em 2010, um estudo transversal (linha de base do Estudo Longitudinal de Avaliação Nutricional de Adolescentes / ELANA) com 1014 adolescentes entre 13 a 19 anos de idade pertencentes ao 1 ano do ensino médio de duas escolas públicas e quatro escolas particulares, localizadas na cidade e na região metropolitana do Rio de Janeiro. O estado nutricional foi avaliado pelo índice de massa corporal (IMC) e a violência familiar na infância por meio do Childhood Trauma Questionnaire (CTQ). Modelos hierarquizados de regressão linear múltipla foram utilizados nas análises. Dos 1014 adolescentes, 53,4% eram do sexo feminino e 50,2% estudavam em escola pública. A prevalência de excesso de peso foi de 26,7%. De acordo com o modelo multivariado, houve uma menor tendência ao excesso de peso na adolescência entre os meninos que sofreram violência do tipo negligência física na infância (β=0,196, 95% CI: 0,346; 0,045, p < 0,011), e de acordo com o aumento da idade para todas as dimensões da violência aferida pelo CTQ (estimativas variaram de 0,136 a 0,126, p < 0.002). O risco de excesso de peso foi maior entre os adolescentes cujos pais apresentavam excesso de peso. Estimativas das variáveis de IMC para mães e pais variaram de 0,065 a 0,066 (p < 0,001) e 0,051 a 0,053 (p < 0,001), respectivamente. Conclui-se que a exposição à violência na infância parece não estar associada com o excesso de peso na adolescência. Foi notada uma tendência de redução do índice de massa corporal em adolescentes do sexo masculino que foram vítimas de negligência física na infância.

O surgimento dos números irracionais

Este é um trabalho de pesquisa sobre um conjunto de números (irracionais) que é pouco trabalhado no ensino básico de matemática. Foi uma procura muito interessante e enriquecedora, pois encontrei matemáticos e historiadores com visões bem diferentes. Muitos deles não aceitavam este novo conjunto. Para Leopold Kronecker, só existia o conjunto dos números inteiros. Já para Cantor e Dedekind, o aparecimento dos irracionais foi extremamente importante para o desenvolvimento da matemática, abrindo novos horizontes. Menciono aqui um pouco da vida e da obra de alguns matemáticos que se envolveram com os números irracionais. Tratamos ainda da descoberta dos incomensuráveis, ou seja, como iniciou-se o problema da incomensurabilidade, e do retângulo áureo e sua importância em outras áreas. O trabalho mostra também dois grupos de números que não são mencionados quando ensinamos equações algébricas, que são os números algébricos e os números transcendentes, assim como teoremas essenciais para a prova da transcendência dos irracionais especiais e . Por fim, proponho uma aula para uma turma do 3 ano do Ensino Médio com o objetivo de mostrar a irracionalidade de alguns números, usando os teoremas pertinentes

Erziehung und Bildung in Offenbach. Bericht 2015

Der Bericht "Erziehung und Bildung in Offenbach. Bericht 2015" (EBO), herausgegeben von Stadt Offenbach am Main, wird zum 9. Mal veröffentlicht. Erstmals wurden Daten der integrierten Ausbildungsberichterstattung für Hessen (iABE) einbezogen. Sie ermöglichen eine wohnortspezifische Analyse der Übergänge von der Sekundarstufe I in unterschiedliche Zielbereiche, wie z.B. Berufsabschluss oder Hochschulreife. Der EBO 2015 bietet vermehrt Zeitreihen, um langfristige Entwicklungen im Bildungsbereich darzustellen. Der Standortbestimmung dienen darüber hinaus interkommunale Vergleiche. Der EBO beinhaltet seit dem Bericht 2009 den von der Jugendhilfeplanung entwickelten „Index bildungsrelevanter sozialer Belastung“. Mit diesem können besondere pädagogischen Bedarfe in den 14 Grundschulbezirken ermittelt und faire, d.h. die unterschiedlichen Anteile bildungsbenachteiligter Schüler/-innen berücksichtigende, Schulleistungsvergleiche ermöglicht werden. Im Rahmen dieser Analyse rücken erstmals die Mädchen mit Migrationshintergrund in den Fokus: So fällt auf, dass im Übergang Grundschule/Gymnasium die Übergangsquote bei Mädchen mit Migrationshintergrund um 15 Prozentpunkte niedriger liegt als die der Mädchen ohne Migrationshintergrund. Sie liegt sogar knapp unter der Übergangsquote der Jungen mit Migrationshintergrund. Eine Erklärung dafür, dass die Mädchen mit Migrationshintergrund beim Übergang zum Gymnasium nicht zu den Bildungsgewinnern zählen, steht aber aus. Der Bericht verdeutlicht auch, dass der Bereich der Sprachförderung in allen Bildungsbereichen – „lebenslang“ – in der Kommune eine herausragende Rolle spielt. Der Bericht greift Linien des "Orientierungsrahmen für Bildungsentwicklung“ der Stadt Offenbach" auf. Der Prozess und die Erarbeitung wurden erstmals von der Fachstelle Bildungskoordinierung und Beratung federführend koordiniert. (DIPF/Autor)

Effects of training peer tutors in content knowledge versus tutoring skills on giving feedback to help tutees’ complex tasks

This study aims to investigate the effectiveness of training tutors in content knowledge of a particular domain versus training them in tutoring skills of pedagogical knowledge when tutoring on a complex tutee task. Forty-seven tutor-tutee pairs of fourth year secondary school students were created and assigned to one of two treatments. Twenty-two tutors received training in content knowledge and the other twenty-five tutors in tutoring skills. Tutors formulated written feedback immediately after the training. Tutees first interpreted the tutor feedback and then used it to revise their research questions. The results showed that tutors trained in tutoring skills formulated more effective feedback than tutors trained in content knowledge. In addition, tutees helped by tutoring-skills tutors found the feedback more motivating than those helped by content- knowledge tutors. However, no differences were found in tutee performance on revision. The findings are discussed in terms of the set-up of this study and implications for improving the effectiveness of peer tutoring.

North Atlantic and North Sea climate change: curl up, shut down, NAO and ocean colour

The strength of the North Atlantic Current (NAC) (based on sea-surface elevation sloped derived from altimeter data) is correlated with westerly winds (based on North Atlantic Oscillation [NAO] Index data over a nine year period [1992-2002] with 108 monthly values). The data time window includes the major change in climate forcing over the last 100 years (1995 to 1996). It is shown that the NAO Index can be used for early earning of system failure for the NAC. The correlation response or early warning time scale for western Europe and south England is six months. The decay scale for the NAC and Subtropical Gyre circulation is estimated as three years. Longer period altimeter elevation/circulation changes are discussed. The sea-surface temperature (SST) response of the North Sea to negative and positive NAO conditions is examined. The overall temperature response for the central North Sea to NAO index forcing, reflecting wind induced inflow, shelf circulation and local climate forcing, is similar to 5 months. In years with strong North Atlantic winter wind induced inflow, under marked NAO positive conditions, mean temperatures ( similar to 10.5 degree C) are about 1 degree C warmer than under negative conditions. In 1996 under extreme negative winter NAO conditions, the North Sea circulation stopped, conditions near the Dogger Bank became more continentally influenced and the winter (March) temperature fell to 3.1 degree C whereas in 1995 under NAO positive winter conditions the minimum temperature was 6.4 degree C (February). Seasonal advance of North Atlantic and North Sea temperature is derived in relation to temperature change. Temperature change and monthly NAO Index are discussed with respect to phytoplankton blooms, chlorophyll-a measurements, ocean colour data and the anomalous north-eastern Atlantic 2002 spring/summer bloom SeaWiFS chlorophyll concentrations.

Development and validation of a molecular technique for the analysis of archived formalin-preserved phytoplankton samples permits retrospective assessment of Emiliania huxleyi communities

The coccolithophores, particularly the species Emiliania huxleyi (Lohmann) Hay & Mohler, account for the bulk of global calcium carbonate production and as such play a fundamental role in global CO2 cycling and the carbonate chemistry of the oceans. To evaluate the response of this functional group to the effects of climate change, we undertook a feasibility study to determine whether a retrospective approach could be used on archived coccolithophore datasets. We demonstrate for the first time a technique for the extraction of E. huxleyi nucleic acids from archived formalin-fixed samples of the long-term Continuous Plankton Recorder. Molecular analysis of a nine year old formalin-fixed sample reveals the presence of a diverse population of E. huxleyi genotypes within a developing coccolithophore bloom. In addition, E. huxleyi sequences were amplified from a number of formalin-fixed samples, the earliest of which was collected in August 1972. This molecular assay promises the possibility of studying global variations in the distribution and genetic make-up of E. huxleyi communities over extensive periods of time. (c) 2008 Elsevier B.V.

The ABC for Life Programme - Teaching Basic Life Support in Schools

Background Less than 1% of the general public know how to assess or manage someone who has collapsed. It has been estimated that if 15–20% of the population were capable of performing cardiopulmonary resuscitation (CPR), mortality of out of hospital cardiac arrest could be decreased significantly. Training basic life support (BLS) skills to school children would be the most cost effective way of achieving this goal and ensuring that a large proportion of the population acquire basic life saving skills. Aims To assess retention of knowledge of basic life support 6 months after a single course of instruction in cardiopulmonary resuscitation designed specifically for school children. Setting School pupils in a rural location in one region of the United Kingdom. Methods A course of instruction in cardiopulmonary resuscitation – the ‘ABC for life’ programme – specifically designed to teach 10–12-year-old school children basic life support skills. The training session was given to school pupils in a rural location in Northern Ireland. A 22 point questionnaire was used to assess acquisition and retention of basic life support knowledge. Results Children instructed in cardiopulmonary resuscitation showed a highly significant increase in level of knowledge following the training session. While their level of knowledge decreased over a period of 6 months it remained significantly higher than that of a comparable group of children who had never been trained. Conclusion A training programme designed and taught as part of the school curriculum would have a significant impact on public health.

Present orientation, future orientation and alcohol use in Northern Irish adolescents

Earlier initiation into more problematic drinking behaviour has been found to be associated with more problematic drinking later in life. Research has suggested that a lower future time perspective (and higher present time perspective) is associated with health-compromising behaviours such as problematic alcohol use in college student, University undergraduate and general population samples. This study used a cross-sectional design to examine whether consideration of future consequences (CFC), assessed by the Consideration of Future Consequences Scale, was significantly related to drinking behaviour in a large sample (n=707) of Northern Irish adolescents. Alcohol use was self-reported by means of a composite measure of drinking behaviour. Demographic data were also gathered. After controlling for year in school (proxy for age), sex and for clustering at school level, lower future orientation and higher present orientation were found to be significantly associated with more problematic self-reported drinking behaviour. These results extend recent findings of a significant relationship between a foreshortened future time perspective and more problematic self-reported drinking behaviour in a UK sample of University undergraduates, to a large UK sample of adolescents. Given the relationship between early-onset drinking and more problematic use in later life, health promotion interventions might explore using the CFC construct in targeting adolescent drinkers.

Consideration of future consequences and alcohol use among Northern Irish adolescents

This study investigated the relationship between consideration of future consequences and alcohol use among adolescents. A cross-sectional design was used and a large sample of 12-to 16-year-old schoolchildren (n = 806) in Northern Ireland were recruited for this study. Alcohol use was assessed using a composite measure of drinking behaviour, the Adolescent Alcohol Involvement Scale. Time perspective was measured using the Consideration of Future Consequences Scale (CFCS). Data were also gathered on self-esteem, three domains of self-efficacy and aggression, all of which have been found to be related to both drinking behaviour and time perspective. Factor analysis of the CFCS revealed support for a two-factor solution, with CFC-I representing present orientation and CFC-F representing future orientation. After controlling for year in school (proxy for age) and gender and for clustering at school level, scores on both subscales were significantly associated with alcohol use. Only CFC-F score remained significant with the addition of psychosocial variables. These results support recent findings of a significant relationship between CFCS score and alcohol use in UK adolescents and University undergraduates, and suggest that in more fully controlled analyses, future orientation, rather than present, is related to adolescent drinking. Results are discussed in relation to health promotion. © 2013 Informa UK Ltd.

Field-Isolated Genotypes of Mycobacterium bovis Vary in Virulence and Influence Case Pathology but Do Not Affect Outbreak Size

Strains of many infectious agents differ in fundamental epidemiological parameters including transmissibility, virulence and pathology. We investigated whether genotypes of Mycobacterium bovis (the causative agent of bovine tuberculosis, bTB) differ significantly in transmissibility and virulence, combining data from a nine-year survey of the genetic structure of the M. bovis population in Northern Ireland with detailed records of the cattle population during the same period. We used the size of herd breakdowns as a proxy measure of transmissibility and the proportion of skin test positive animals (reactors) that were visibly lesioned as a measure of virulence. Average breakdown size increased with herd size and varied depending on the manner of detection (routine herd testing or tracing of infectious contacts) but we found no significant variation among M. bovis genotypes in breakdown size once these factors had been accounted for. However breakdowns due to some genotypes had a greater proportion of lesioned reactors than others, indicating that there may be variation in virulence among genotypes. These findings indicate that the current bTB control programme may be detecting infected herds sufficiently quickly so that differences in virulence are not manifested in terms of outbreak sizes. We also investigated whether pathology of infected cattle varied according to M. bovis genotype, analysing the distribution of lesions recorded at post mortem inspection. We concentrated on the proportion of cases lesioned in the lower respiratory tract, which can indicate the relative importance of the respiratory and alimentary routes of infection. The distribution of lesions varied among genotypes and with cattle age and there were also subtle differences among breeds. Age and breed differences may be related to differences in susceptibility and husbandry, but reasons for variation in lesion distribution among genotypes require further investigation. © 2013 Wright et al.

Femoral exostosis causing vastus medialis pain in an active young lady: a case report.

BACKGROUND:
Musculoskeletal conditions are a common reason for consultation to General Practitioners (GPs)/family physicians in primary care. Osteochondromas are the most common benign bone tumours and usually occur in the metaphyseal region of long bones. Despite the distal femur being the commonest location to find these benign bone tumours, this is the first case report in the literature specifically describing vastus medialis muscle pain as the presenting symptom due to underlying bursa formation secondary to local pressure effects.

CASE PRESENTATION:
Twenty nine year old female of white British ethnic origin, presenting to a primary care clinic with a three year history of intermittent left distal medial thigh pain.

CONCLUSION:
The benign bone tumour, femoral exostosis/osteochondroma, was diagnosed via Magnaetic Resonance Imaging (MRI) and treated conservatively, with surgical excision an option if not resolving. GPs/family physicians need to be aware of this diagnosis and that femoral exostosis/osteochondroma can present to primary care physicians, particularly within the second decade of life.
