Middle-aged women negotiating the ageing process through participation in outdoor adventure activities

This study sought to examine the motivations middle-aged women give for belonging to an outdoor adventure group. As part of this, how the women were negotiating the ageing process was also examined. Fourteen women aged 36–64 (average age 51.4 years) were individually interviewed with the purpose of exploring their perceptions, values, motivations and the beliefs they attach to their participation. Findings highlight the women’s belief that participation delays the ageing process, gives them confidence in their lives and offers social support from other group members. In addition, pride, satisfaction and pleasure were expressed in the belief that they challenged the cultural norms and expectations of older women. Whilst delaying the ageing process, they also highlighted that they thought about a time in the future when they would not be able to continue to participate. The study emphasises that more adventurous activities are becoming more normalised and can be undertaken by women in middle age. This may also suggest that more needs to be done to promote diverse activities such as outdoor adventurous activities to women

Living up to our students’ expectations – using student voice to influence the way academics think about their undergraduates learning and their own teaching

Understanding the student learning experience is essential if Higher Education Institutions (HEI) are to provide an education for the 21st century. This study investigated students’ perspectives on their learning experiences and offered undergraduates a chance to influence the way academics think about learning and teaching.Participants were drawn from two UK HEIs and a semi structured focus group approach was adopted. A total of nine focus groups consisting of 3-7 participants were drawn from across all Sport degree year groups in both institutions. Assessment, pedagogy and teacher characteristics emerged as primary concerns across both institutions. Assessment was appreciated by all students as key to their learning but was exposed as being overly traditional and rigid in its application. Students were unanimous in their support for small group pedagogies, rejecting traditional powerpoint dominated lecturing styles. The emphasis on the behaviour of, and delivery by, tutors was noteworthy.Students appraised the development of their academic skills and confidence, linking these to motivation, knowledge, self-awareness and critical reflection. In doing so they understood the impact of inconsistencies in tutors’ teaching practices. The onus is on every tutor to combine imaginative assessment with dynamic and relational experiences in order to provide a strong foundation for flexible, reflective and creative graduates

Tracking career destinations of sports graduates 2000-2015:a longitudinal exploration of destinations and preparedness for the workplace

The advent of the TEF means that universities will be expected to evidence the impact of curriculum interactions on graduate destinations and social mobility. Over a third of sport employees are graduates but little data charts their career journeys. Key objectives: • track all Abertay sport graduates from the programmes’ inception • compare Honours and non-Honours graduates’ destination data • examine career trajectories • explore preparedness for the workplace • utilise demographic data to contextualise findings. 452 graduates were e-mailed.123 responded to the survey, 84% being in identifiable graduate level jobs. Across time, increasing proportions of students were Honours' graduates. Social class, gender and disability did not impact on this but articulation from FE was a significant factor (χ2 =84.68, p<0.01). Very few respondents (n=13) felt that their degree had not equipped them for working life. 'Placement' and 'research methods skills' were of most benefit in preparing for the workplace

Phenomenological model for predicting the energy resolution of neutron-damaged coaxial HPGe detectors

The peak energy resolution of germanium detectors deteriorates with increasing neutron fluence. This is due to hole capture at neutron-created defects in the crystal which prevents the full energy of the gamma-ray from being recorded by the detector. A phenomenological model of coaxial HPGe detectors is developed that relies on a single, dimensionless parameter that is related to the probability for immediate trapping of a mobile hole in the damaged crystal. As this trap parameter is independent of detector dimensions and type, the model is useful for predicting energy resolution as a function of neutron fluence.Comment: 7 pages, 7 figure

Application of digital terrain data to quantify and reduce the topographic effect on LANDSAT data

Integration of LANDSAT multispectral scanner (MSS) data with 30 m U.S. Geological Survey (USGS) digital terrain data was undertaken to quantify and reduce the topographic effect on imagery of a forested mountain ridge test site in central Pennsylvania. High Sun angle imagery revealed variation of as much as 21 pixel values in data for slopes of different angles and aspects with uniform surface cover. Large topographic effects were apparent in MSS 4 and 5 was due to a combination of high absorption by the forest cover and the MSS quantization. Four methods for reducing the topographic effect were compared. Band ratioing of MSS 6/5 and MSS 7/5 did not eliminate the topographic effect because of the lack of variation in MSS 4 and 5 radiances. The three radiance models examined to reduce the topographic effect required integration of the digital terrain data. Two Lambertian models increased the variation in the LANDSAT radiances. The nonLambertian model considerably reduced (86 per cent) the topographic effect in the LANDSAT data. The study demonstrates that high quality digital terrain data, as provided by the USGS digital elevation model data, can be used to enhance the utility of multispectral satellite data

Paleolakes and life on early Mars

Two distinct directions have begun to elucidate key parameters in the search for extinct life on Mars. Carbonate sediments, deposited about 10,000 years ago in association with biological activity, have been sampled from the paleolake beds of Lake Vanda and Meirs in the McMurdo Dry Valleys in Antarctica. These samples are being analyzed for simple biological signatures that remain in cold and dry paleolake sediments, namely microfossils, percent carbonate, and total organic carbon. Our second initiative is the study of Colour Lake, in the Canadian Arctic, that periodically maintains a perennial ice cover. Physical measurements started this year will be used to determine one end point for ice covered lake environments and will be compared to continuous measurements from Antarctic lakes started in November 1985. Interestingly, Colour Lake also supports benthic mat communities, but the low pH precludes carbonate deposition. This research will broaden our knowledge base for what conditions are necessary for ice covered lake formation and what biological signatures will remain in paleolake deposits
