Background: The Framework Method is becoming an increasingly popular approach to the management and analysis of qualitative data in health research. However, there is confusion about its potential application and limitations. Discussion. The article discusses when it is appropriate to adopt the Framework Method and explains the procedure for using it in multi-disciplinary health research teams, or those that involve clinicians, patients and lay people. The stages of the method are illustrated using examples from a published study. Summary. Used effectively, with the leadership of an experienced qualitative researcher, the Framework Method is a systematic and flexible approach to analysing qualitative data and is appropriate for use in research teams even where not all members have previous experience of conducting qualitative research. © 2013 Gale et al.; licensee BioMed Central Ltd.

A study was conducted to investigate the effectiveness, as measured by performance on course posttests, of mindmapping versus traditional notetaking in a corporate training class. The purpose of this study was to increase knowledge concerning the effectiveness of mindmapping as an information encoding tool to enhance the effectiveness of learning. Corporations invest billions of dollars, annually, in training programs. Given this increased demand for effective and efficient workplace learning, continual reliance on traditional notetaking is questionable for the high-speed and continual learning required on workers.^ An experimental, posttest-only control group design was used to test the following hypotheses: (1) there is no significant difference in posttest scores on an achievement test, administered immediately after the course, between adult learners using mindmapping versus traditional notetaking methods in a training lecture, and (2) there is no significant difference in posttest scores on an achievement test, administered 30 days after the course, between adult learners using mindmapping versus traditional notetaking methods in a training lecture. After a 1.5 hour instruction on mindmapping, the treatment group used mindmapping throughout the course. The control group used traditional notetaking. T-tests were used to determine if there were significant differences between mean posttest scores between the two groups. In addition, an attitudinal survey, brain hemisphere dominance survey, course dynamics observations, and course evaluations were used to investigate preference for mindmapping, its perceived effect on test performance, and the effectiveness of mindmapping instruction.^ This study's principal finding was that although the mindmapping group did not perform significantly higher on posttests administered immediately and 30 days after the course, than the traditional notetaking group, the mindmapping group did score higher on both posttests and reported higher ratings of the course on every evaluation criteria. Lower educated, right brain dominant learners reported a significantly positive learning experience. These results suggest that mindmapping enhances and reinforces the preconditions of learning. Recommendations for future study are provided. ^

The purpose of this thesis is to analyze how João Café Filho constituted a discourse of advocate of the labor movement and workers in different sociability spaces. It is intended to understand, on one hand, how political relations were established between different categories of workers and the ‘middle classes’ and, on the other hand, how places were instituted to house the meeting of these relations. It a ims to understand the insertion of Café Filho in union activities in the urban world. It demonstrates specificities of the political culture in Natal emphasizing the dispute between a city politically ruled by a still reigning rural paternalistic mentality and the rise of a new way to experience the urban conflicts which appeared. Temporally, the work is delimited between 1922 (proclaimed by Café Filho himself as the initial period of his political action) and 1937 (when he broke up with Vargas and went into exile in Argentina). The research was constituted by three main document types: several published newspapers between the decades of 1920 and 1930 in the cities of Natal, Recife, São Paulo, Porto Alegre and Rio de Janeiro; the autobiographical memoirs written by Café Filho himself and memoirs of other people who lived in his time. The main pillars that have supported the work were: the concepts of society and individuals (ELIAS, 1994; 1995), political cultures (BERSTEIN, 1998) and theater of the memory (GOMES, 2004); the sociability spaces category (CERTEAU, 1994; MALATIAN, 2001; RIOX, 1996); the biography notion (DOSSE, 2009; LORIGA, 2011). We demonstrated that Café Filho acted in some sociability spaces as: the Jornal do Norte, the Federação Regional do Trabalho and the Partido Democrático Nacional. In such spaces, Café Filho, gradually, become an important leader of workers and, at the same time, linked to national entities led to the opposition that fight against the power established in the Brazilian First Republic. In Café Filho’s interpretation, workers were individuals who needed to fight against the political structures prevailing at that time because the poor living conditions and the low representativeness of this group were caused by the way the political system in the First Republic was structured. After the 1930 Movement, the 3 de Outubro Club, the Jornal and the Labor Federation of Natal were constituted in spaces where the cafeista critical discourse about the government was changed: workers should follow the official syndicalism and defend the 1930 Movement which put Vargas in the presidency of the Republic.

Ocean Drilling Program (ODP) Leg 207, on the Demerara Rise in the western tropical North Atlantic, recovered multiple Cretaceous-Paleogene boundary sections containing an ejecta layer. Sedimentological, geochemical, and paleontological changes across the boundary closely match patterns expected for a mass extinction caused by a single impact. A normally graded, ~2-cm-thick bed of spherules that is interpreted as a primary air-fall deposit of impact ejecta occurs between sediments of the highest Cretaceous Plummerita hantkeninoides foraminiferal zone and the lowest Paleogene P0 foraminiferal zone. There are no other spherule layers in the section. In addition to extinction of Cretaceous taxa, foraminiferal abundance drops from abundant to rare across the boundary. Ir concentrations reach a maximum of ~1.5 ppb at the top of the spherule bed, and the Ir anomaly is associated with enrichment in other siderophile elements. We attribute the unusually well-preserved and relatively simple stratigraphy to the fact that Demerara Rise was close enough (~4500 km) to the Chicxulub impact site to receive ~2 cm of ejecta, yet was far enough away (and perhaps sheltered by the curve of northern South America) to have been relatively unaffected by impact-induced waves.

Introdução: A CIF foi considerada, por alguns clínicos, como não sendo totalmente viável para a aplicação na rotina clínica, já que este sistema de classificação contém mais de 1400 categorias. Posto isto, o processo de desenvolvimento de Core Sets da CIF tem sido priorizado pela OMS, tornando a CIF acessível para a avaliação das cs específicas. Estes pretendem orientar uma avaliação multidisciplinar abrangente, incluindo as categorias da CIF para descrever, de uma forma suficiente, a funcionalidade e incapacidade dos indivíduos. Contudo, podem existir divergências entre a perspetiva de crianças e jovens portugueses com PC e cuidadores sobre a sua cs e os core sets da CIF estabelecidos para a mesma. Objetivo: Identificar os problemas percecionados pelas crianças e jovens com paralisia cerebral e pelos cuidadores em Portugal e analisar em que medida estes aspetos são representados pela versão atual do Comprehensive Core Set da CIF para esta cs. Metodologia: Este estudo é qualitativo, tendo-se utilizado uma amostra conveniente de crianças/jovens com PC e cuidadores. Todos os dados foram recolhidos por meio de entrevistas e posteriormente analisados segundo o protocolo de Coenen. Foi efetuado o linking dos conceitos obtidos das entrevistas para as categorias da CIF, tendo sido comparadas com os Core Sets da CIF para esta condição. Resultados: Este estudo tem uma amostra de 48 indivíduos, sendo que 28 eram crianças e jovens com PC e os restantes 20 eram cuidadores. A média de idades das crianças/jovens incluídos foi 13,04 (±3,26), sendo que a idade mínima incluída foi 8 anos e a idade máxima, 18 anos. A média de idades dos cuidadores incluídos foi de 35,20 (±8,01) anos, sendo que a idade mínima incluída foi 22 anos e a idade máxima 55 anos. Das 256 categorias identificadas, 101 estão contempladas nas categorias dos Comprehensive Core Set da CIF. Estas encontram-se presentes em 58 categorias de 2º nível dos Comprehensive Core Set de um total de 135, correspondendo a 43% dos mesmos. Conclusões: Tendo em conta os resultados obtidos, podemos concluir que os Comprehensive Core Set da CIF para a PC contemplam a grande maioria dos problemas percecionados pela população-alvo, ainda que integre várias categorias que não foram relevantes para esta população em estudo.

Juniperus navicularis Gand. is a dioecious endemic conifer that constitutes the understory of seaside pine forests in Portugal, areas currently threatened by increasing urban expansion. The aim of this study is to assess the conservation status of previously known populations of this species located on its core area of distribution. The study was performed in south-west coast of Portugal. Three populations varying in size and pine density were analyzed. Number of individuals, population density, spatial distribution and individual characteristics of junipers were estimated. Female cone, seed characteristics and seed viability were also evaluated. Results suggest that J. navicularis populations are vulnerable because seminal recruitment is scarce, what may lead to a reduction of genetic variability due solely to vegetative propagation. This vulnerability seems to be strongly determined by climatic constraints toward increasing aridity. Ratio between male and female shrubs did not differ from 1:1 in any population. Deviations from 1:1 between mature and non-mature plants were found in all populations, denoting population ageing. Very low seed viability was observed. A major part of described Juniperus navicularis populations have disappeared through direct habitat loss to urban development, loss of fitness in drier and warmer locations and low seed viability. This study is the first to address J. navicularis conservation, and represents a valuable first step toward this species preservation.

The RAGE Exploitation Plan is a living document, to be upgraded along the project lifecycle, supporting RAGE partners in defining how the results of the RAGE RIA will be used both in commercial and non-comercial settings. The Exploitation Plan covers the entire process from the definition of the business case for the RAGE Ecosystem to the creation of the sustainability conditions for its real-world operation beyond the H2020 project co-funding period. The Exploitation Plan will be published in three incremental versions, due at months 18, 36 and 42 of the project lifetime. This early stage version 1 of 3 is mainly devoted to: i. Setting-up the structure and the initial building blocks to be populated and completed in the future editions of the Exploitation Plan and to ii. providing additional guidance for market intelligence gathering, business modelling definition and validation, outreach and industry engagement and ultimately providing insights for the development, validation and evaluation of RAGE results across the project´s workplan execution. These tasks will in turn render suitable inputs to enhance the two future editions of the Exploitation Plan.

Finländska elever presterar fortsättningsvis bra i matematik men deras inre motivation till ämnet är klart under medelnivån för OECD-länderna. Det finns ett konstaterat samband mellan intresse och prestationer, och att höja elevernas intresse vore därför viktigt. Användningen av dataspel i undervisningen möjliggör just detta då det kunde höja elevernas motivation och intresse. Det finns en del tidigare forskning om hur dataspel påverkar inlärningen, men eftersom området fortfarande är relativt nytt finns luckor att fylla. De övergripande resultaten inom området inlärning genom dataspel är positiva och lovande. Tidigare forskning visar att användningen av dataspel i matematikundervisningen har en positiv inverkan på elevernas prestationer. Man har också kunnat konstatera att användningen av dataspel i undervisningen påverkar elevernas attityder till ämnet positivt, men forskning om hur specifika affektiva faktorer som intresse, självuppfattning och matematikångest påverkas saknas. Syftet med avhandlingen är att undersöka effekten av dataspelet MinecraftEdu på finländska studerande inom yrkesutbildningen. Forskningsfrågorna som avhandlingen utgår ifrån är följande: Hur påverkar användningen av MinecraftEdu i matematikundervisningen låg- och normalpresterande studerandes 1) matematiska färdigheter, 2) intresse för matematik, 3) matematiska självuppfattning och 4) matematikångest? Forskningsmetoden är kvantitativ och datainsamlingen har genomförts med hjälp av en webbenkät och det standardiserade testet RMAT samt 8 problemlösningsuppgifter. Respondenterna bestod av andra årets studerande inom den finländska yrkesutbildningen. Experimentgruppen som bestod av studerande inom datanomutbildningen undervisades med hjälp av dataspelet Minecraft. Kontrollgruppen, bestående av studerande inom utbildningen för fordonsmekaniker, undervisades traditionellt. Data samlades in vid två tillfällen, före och efter avslutad kurs. Som analysmetod valdes en kovariansanalys. Resultaten av undersökningen tyder på att användningen av MinecraftEdu kan ha positiva effekter på studerandes matematiska färdigheter, speciellt problemlösningsfärdigheter. Resultaten tyder också på att lågpresterande studerande kan gynnas av undervisning genom MinecraftEdu, speciellt med tanke på matematiskt intresse och matematiska färdigheter. Skillnaderna mellan grupperna var dock inte signifikanta och resultaten kan därför inte generaliseras. Resultaten ger däremot en uppfattning om vilken effekt den här typen av undervisning kan ha.
