The validity and reliability of focus groups as a research method in adult education

The article examines the theory and practice of focus groups in adult education research. Three theoretical positions are described: radical hermeneutic, moderate interpretative and pragmatic realistic position trying to bridge the gap with positivist research. This last position has been chosen as the departure point for a further analysis of the focus group elements, which relate to validity and reliability. The research examines four European research projects in the field of adult education. The most important and surprising data are presented with reference to both socio-psychological and technical problems in the use of this method. The results highlight the importance and dynamics of all the elements discussed.     

New methods for life course analysis of lifelong education

Studies of the impact of education on adults’ lives must go beyond the background details of students, the course and the immediate learning outcomes, and be grounded in the changing lives of learners in a changing world. Life histories provide a rich source of data to assess the significance of education but are difficult to analyse. New approaches based on life course analysis show at what stage in students’ various ‘careers’ they participate, what else is going on at the time, and how education affects areas of their lives. The paper begins with a brief review of the literature on collecting life histories and a justification for the method adopted which provides the starting point for life course analysis. A case study of a student living in an area of multiple deprivation who took an Open University community education course is presented to show how life course analysis can be carried out and the place and influence of education evaluated.     

‘Science to the Glory of God’. The Popular Science Magazine Ibérica and its Coverage of Radioactivity, 1914–1936

This paper provides a first approach to the history of Ibérica, one of the most important popular science magazines published in Spain before the Civil War. Founded in 1914 by members of the Society of Jesus based at the Ebro Observatory, Ibérica reached a weekly circulation of about 10,000 in the mid 1920s, and was instrumental in extending science education in Jesuit education facilities and in developing a “reactionary modernist” culture that embraced Catholicism and modernisation. By focusing on its coverage of radioactivity and the radium industry, the article aims to examine the magazine’s popularising style and ideology, and to determine its role in the debates regarding the cultural value of science in the first decades of twentieth century Spain.     

Analysis of publications of the pilot issue of the data collection of the All-Russia Institute of Scientific and Technical Information of the Russian Academy of Sciences “Industry of Nanosystems and Nanomaterials”

The pilot issue of the data collection of the All-Russian Institute of Scientific and Technical Information of the Russian Academy of Sciences “Industry of Nanosystems and Nanomaterials” gives an approximate view of the state of this field of science at the beginning of 2007. The topics of articles in the pilot issue are analyzed. The directions of development of nanotechnologies are shown. The basic types of nanomaterials, the methods of their production, and their properties and applications are given.     

Definitions of a “document”

Although the definition of a document has been the subject of a vast number of works, analysis of the latest publications shows that the question remains controversial. In this article the two definitions of “document” accepted as the broadest ones, i.e., the principal and conventional ones, are taken for examination. The principal definition of a document starts from the document as a part in the social information-communication process, therefore, having its place in it and performing a function that is major, and obligatory for the document. The conventional definition limits the scope of this concept, mostly in terms of material and characters, with allowance for specific features in the operation of documental communication systems.     

A web of science databases as a criterion for assessment of the research activities of Belarusian scientists

The publication activity of the scientists of the National Academy of Sciences of Belarus, the degree of reflection of their papers in Web of Science databases, and the data on the citation of Belarusian researchers in the studies of other scientists are discussed.     

Investigation of the flow of scientific-technical information on the basis of the Russian technical literature on nanostructures and nanotechnologies

The objective of this investigation of the Russian technical literature on nanostructures and nanotechnologies is a study of the dynamics and the cumulative number of publications (CPN) concerning nanostructures and nanotechnologies, the dynamics an2 CPN for different types of publications, the publication productivity of Russian scientists and Russian cities concerning nanostructures and nanotechnologies, the scientific activity of Russian scientific-research and educational institutions concerning nanostructures and nanotechnologies, the investigation of Russian periodicals and continuing publications concerning nanostructures and nanotechnologies, and the simulation of the CPN and prediction of the CPN for nanostructures and nanotechnologies.     

Submaximal exercise and maturation in 12-year-olds

The aim of this study was to examine the maturation responses of young people to submaximal treadmill exercise. Body mass was controlled using both the conventional ratio standard and allometric modelling. Ninety-seven boys and 97 girls with a mean age of 12.2 years completed a discontinuous, incremental exercise test to voluntary exhaustion. We measured peak oxygen uptake (VO2peak) and VO2 when running at 8, 9 and 10 km x h(-1). Sexual maturation was assessed visually using Tanner's indices of pubic hair. Peak VO2 was significantly higher in boys (P<0.001); this was still the case when the influence of body mass was covaried out. During submaximal exercise, no significant differences in absolute VO2 were observed between the sexes (P>0.05); however, values of VO2, expressed both in ratio with body mass and adjusted for body mass using allometry, were significantly greater in boys than in girls (P<0.001). For absolute VO2, significant main effects (P<0.05) were seen for maturity at each exercise stage. With the influence of body mass controlled using either the ratio standard or allometry, no significant main effects (P>0.05) for maturity were observed. Our results indicate that boys are less economical than girls while running at 8-10 km x h(-1) and that, independently of body mass, maturation does not influence the VO2 response to submaximal exercise.
