The purpose of the present study was to investigate the level of physical activity (PA) in an all-boys school and, using a mixed method design, to identify factors that facilitate or hinder PA engagement. Participants ( n = 382) completed the Three Day Physical Activity Recall (3DPAR) questionnaire to enable examination of the pattern of their PA and the amount of time spent on sedentary activities. To understand further the motivation behind their level of PA, 24 participants with the highest and lowest 3DPAR scores were selected for focus groups. Quantitative data of the PA levels of the all-boys sample of this study and those of a mixed sample from a study by Lee and Trost were analysed using percentage means with 95% confidence intervals, with a 2x2 analysis of variance being used for the comparisons. The focus group data were transcribed and thematic analysis was performed on the transcripts. The quantitative results revealed evidence that male students in the current sample were more active in comparison with the students from the mixed sample. The qualitative results indicated that PA participation was facilitated by factors such as intention to maintain health and fitness levels, a strong school sports culture, regular exercise with friends and family, and an individual’s exercise history. In contrast, academic workload, poor exercise history and after-school non-PA related activities were identified as factors that hindered PA participation. The findings are discussed in relation to wider school decisions and policies that have an effect on PA among adolescent students.

The innovations of the twenty-first century in digital technology and media have had major influences in the way young urbanites and future city designers think as well as experience places. In embracing this conceptual shift of how new communication technologies are changing people’s perceptions, experiences and ways of knowing the city, Oxford Brookes University continues to develop pedagogical methods which use new media in the teaching, learning and production of contemporary urban design.These methods are examined in this paper in the context of three undergraduate modules:• Taking the urban design learning experience out of the classroom and into the field using mobile lectures;• Using digital media in research and engaging with oral, visual and sensory experiences;• Developing design communication skills using video, animation, interactive PDFs and website design;• Bringing new perspectives to classic theoretical concepts by engaging with different media: Cullen’s Townscape from serial expe...

An approach to restriction-site mapping and contig building that uses fragment-size data from multiple complete digests of a set of clones that oversample a genomic region is presented. Maps containing both fragment-length data and clone-end data are maintained for each restriction enzyme. Synchronization between the maps for the different enzymes is achieved by requiring the clone-end maps for all enzymes to be compatible. Basic concepts that underlie multiple-complete-digest mapping - including the match/merge approach to map incorporation, extension vs. assimilation, ambiguity, and clone-end compatibility - are presented. An initial application of multiple-complete-digest mapping to real data on a set of cosmid clones suggests that this mapping method has exceptional power to produce accurate maps that are well suited to the needs of large-scale DNA-sequencing projects. 31 refs., 7 figs., 2 tabs.
