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.

Art as an educative and social tool

Since remote times, certain sectors of society have been exposed to inequality and vulnerability, where adequate intervention processes have become conspicuous because of their absence. Nowadays, current societies have the responsibility of contributing, based on their experience and knowledge, with more efficient policies and programs that improve the life quality of the most disadvantaged. It is here where art and its different tools play a very important role, not only on a physical level, but also as an education tool that allows the development of emotional, mental and communicative skills. The aim of this paper is to make clear the potential of art as an instrument of social and educational intervention. It starts by showing worldwide-collected experience related to education and arts, and then, it acquaints the reader with two parallel intervention projects that worked with youths under social vulnerability conditions. These interventions were developed based on a qualitative research (Grounded theory), using as methodology “The Artistic Mediation” with emphasis on body language. This methodology helped researchers to get close to the participants and to know their experiences and emotions. At the same time, it was possible to evidence the positive effects of educative interventions through art. These workshops were based on an artistic methodology especially focused on body language. Data in this work is qualitative, and as such, it permits a special approach to the personal and emotional experiences of the participants; clearly showing the positive effects of the referenced practice on them.

Instrumentos de evaluación utilizados en la formación inicial del profesorado y su coherencia para el desarrollo de competencias profesionales en los estudiantes: visión del alumnado, egresados y profesorado

El objetivo de este trabajo es analizar la frecuencia con que se utilizan diferentes instrumentos y procedimientos de evaluación desde el punto de vista del profesorado, del alumnado y de los egresados en la formación inicial de maestros y profesores especialistas en Educación Física, así como el grado de coherencia –relación- percibido por cada uno de esos grupos implicados entre dichos instrumentos y procedimientos de evaluación y el desarrollo de las competencias profesionales que se pretende adquieran los estudiantes. La muestra objeto de estudio está compuesta por 199 alumnos, 67 egresados y 53 profesores de las titulaciones de Magisterio (especialidad de Educación Física) y Ciencias de la Actividad Física y el Deporte de las universidades de Valladolid, Salamanca y León. Los resultados muestran una clara discrepancia entre los distintos grupos analizados, tanto en lo referido al tipo de instrumentos de evaluación utilizados, como en la valoración del grado de coherencia entre estos y el desarrollo de las competencias profesionales de los futuros maestros.

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.

Process Evaluation of the Roots of Empathy Program

This paper presents the findings of a qualitative process evaluation of the Roots of Empathy (ROE) programme. ROE is a universal, classroom-based intervention, which aims to enhance social and emotional learning of primary (elementary) school children. Effective delivery of such complex social interventions in real-world settings requires in-depth knowledge and understanding of factors that interact to influence implementation and fidelity. A case study methodology was employed with six schools, to explore the views of key actors and stakeholders involved in the delivery and receipt of the programme. Overall, ROE was delivered with high fidelity and the programme was viewed positively across the schools. However, one issue was the varied level of interest and awareness of the programme from parents.

Clubes de ciências e o percurso escolar dos alunos

Os factores que levam os alunos, no final da escolaridade obrigatória, a escolher o seu percurso escolar são vários. Neste estudo procurou-se saber em que medida a frequência de Clubes na área das Ciências influenciam essa decisão e, ainda, estudar como potenciar a sua organização no sentido de que estes possam contribuir positivamente para as escolhas dos alunos por percursos escolares na área das Ciências. A investigação decorreu em duas fases. Na primeira fase, foi avaliada a influência dos Clubes de Ciências na decisão do percurso escolar dos alunos, no final da escolaridade básica. Nesta fase foram realizados os seguintes procedimentos: -Entrevista semi-estruturada realizada a sete professoras responsáveis de Clubes na área das Ciências Físicas e Naturais, de 7 Escolas Secundárias da região de Aveiro. -Administração de um questionário, construído com questões maioritariamente fechadas, a uma amostra de 106 alunos, do 10ºAno, provenientes de 11 Escolas Secundárias da região de Aveiro, que frequentaram Clubes na área das Ciências Físicas e Naturais, no 3º Ciclo. -Tratamento estatístico das questões do questionário, com recurso ao programa SPSS (Statistical Package for the Social Science) e análise de conteúdo das questões abertas do questionário e das entrevistas, recorrendose para o efeito à construção de categorias de resposta. Na segunda fase concebeu-se e implementou-se um Clube de Ciências. Nesta fase surgiu a criação do Clube: ”Educação para o Desenvolvimento Sustentável”, no qual foi desenvolvido o projecto: “Construção e dinamização de uma Estação Meteorológica”, numa Escola Básica do 2º e 3º Ciclos do Concelho de Aveiro. Os resultados obtidos na primeira fase do estudo são reveladores da importância que é atribuída às experiências vivenciadas pelos alunos nos Clubes de Ciências que frequentaram. Os temas/assuntos abordados foram essencialmente conteúdos ligados a áreas do conhecimento das disciplinas de Ciências. Predominaram as estratégias com base em trabalho de projecto e em actividades experimentais. Indicadores nacionais e internacionais têm evidenciado um decréscimo no número de jovens que, na sua escolaridade, optam por estudos nas áreas das Ciências e da Tecnologia. Este decréscimo tem sido um factor de preocupação ao nível das políticas educativas, nomeadamente europeias, tornando-se urgente, por um lado, compreender o porquê desse facto e, por outro, encontrar formas de o minimizar. Os Clubes na perspectiva das responsáveis entrevistadas: (a) Surgem como uma oportunidade para melhorar as competências dos alunos ao nível do saber fazer; (b) Permitem confirmar e reforçar a motivação e o gosto pelas Ciências; (c) Podem, também, dar-lhes orientações para o futuro, embora esta não tenha sido uma preocupação explícita; (d) São do agrado dos alunos devido a apresentarem actividades não meramente académicas e formais. Os Clubes, na perspectiva dos alunos respondentes: (a) Aumentaram a motivação para estudar Ciências; (b) Permitiram relacionar as Ciências com o dia-a-dia; (c) Ajudaram na escolha do curso que frequentam no Ensino Secundário; (d) Contribuíram para querer exercer uma profissão na área das Ciências. Na segunda fase do estudo, foi desenvolvido um trabalho de projecto que envolveu alunos do 3º Ciclo. O tema do projecto, proposto e implementado, coincidiu com os dois temas menos abordados, nos Clubes frequentados pelos respondentes da primeira fase do estudo, Meteorologia e Temáticas com Impacto Social. Por outro lado o Clube pretendeu contribuir para a Década da Educação para o Desenvolvimento Sustentado, instituída pelas Nações Unidas, para fazer frente à actual situação de emergência planetária. Uma estratégia privilegiada para formar cidadãos capazes de assumir atitudes e valores com vista ao desenvolvimento sustentável, passa pela Educação em todas as suas vertentes, nomeadamente a do ensino não formal, na qual se incluem os Clubes de Ciências. ABSTRACT: National and international indicators have showed a decrease in the number of youngsters that, during their school course make their choices in the study areas of Science and Technology. This decreasing tendency has been a motive of concern as far as the European educational policies are concerned. Thus, it is urgent to understand the reason behind that situation and find ways to minimize it. There are various factors that make students choose their study areas in the end of their school course. This study aimed to find out how the Science Clubs can influence their decisions as well as to study new ways to improve their organization in such a way that they may contribute positively to the students’ choices of their school careers in the area of Science. The investigation was divided in two parts: in the first part, it was evaluated the level of the influence of the Science Clubs in the students’ school careers at the end of the elementary education. At this stage it was adopted the following procedure: -A semi-structured interview was applied to 7 female teachers that are responsible for the Natural and Physics Science Clubs, in secondary schools, in the region of Aveiro; -A mainly close-question questionnaire was applied to a sample of 106 students, in the 10th grade, in 11 secondary schools, in the region of Aveiro. These students have attended some Natural and Physics Science Clubs, during the 7th, 8th and 9th grades; -Statistical work of the questionnaire was done with the help of the SPSS programme (Statistical Package for the Social Science) as well as the analysis of the contents of the open-questions of the questionnaire and the interviews by means of the answer-category method. In the second part, a Science Club was planned and implemented. At this stage, a club was created - “Education for the Sustainable Development” - within which the following project was developed – “Building and Development of a Meteorological Observatory”, at a 2nd and 3rd Ciclos (Stages) Elementary School, in Aveiro. The results of the first part of this study case have showed clearly the importance given to the experiences of the students while attending the Science Clubs. The themes/subjects studied were mainly science knowledgerelated contents. The strategies adopted were based on project work and experimental activities. A view of the Clubs by the people who are responsible for them: (a)The Clubs mean an opportunity for students to learn the know-how process; (b)They have provided the reinforcement of the motivation and preference for Science; (c)Although it was not the main concern with the clubs, the truth is that they can also give the students a sense of awareness for the future; (d)Students like to make part of the clubs because of their experimental character. A view of the Clubs by the students who make part of them: (a)The clubs have increased the level of motivation to study Science; (b)They have allowed a close perspective of the daily life reality; (c)They have helped with the choice of the Secondary School courses; (d)They have made students want a future professional career in the area of Science. In the second part of this study case, a project work was carried out involving 7th, 8th and 9th grade students. The subject of the project, considered and implemented, coincided with the two less boarded subjects, in the Clubs attended a course for the respondents of the first phase of the study, Meteorology and Thematic with Social Impact. The Club also aimed to contribute to the decade of the “Education for the Sustained Future” as settled by the United Nations in order to face the present emergency situation of the planet. The last but not the least, it is believed that, the best strategy to teach future citizens who are able to take the responsibility of their values and attitudes towards a sustainable future, is to provide them a type of Education that can teach them both the formal curriculum aspects and the informal ones, as it is the case of the Science Clubs.
