A model of melt pond evolution on sea ice

A one-dimensional, thermodynamic, and radiative model of a melt pond on sea ice is presented that explicitly treats the melt pond as an extra phase. A two-stream radiation model, which allows albedo to be determined from bulk optical properties, and a parameterization of the summertime evolution of optical properties, is used. Heat transport within the sea ice is described using an equation describing heat transport in a mushy layer of a binary alloy (salt water). The model is tested by comparison of numerical simulations with SHEBA data and previous modeling. The presence of melt ponds on the sea ice surface is demonstrated to have a significant effect on the heat and mass balance. Sensitivity tests indicate that the maximum melt pond depth is highly sensitive to optical parameters and drainage.

An examination of business occupier relocation decision making : distinguishing small and large firm behaviour

This paper explores how business occupiers decide whether and where to relocate. It captures the experience and behaviour of a range of sizes and types of business occupier and subjects their decision-making processes to detailed scrutiny. A linear three-stage decision model is used to sequence and structure interviews with individuals who have intimate involvement with the relocation of 28 firms and organizations in Tyne and Wear, in the north-east of England. The 'constant comparative' method is used to analyse the interview data, from which emerges 18 key concepts, comprising 51 characteristic components. Using an axial approach, these are organized into 10 cross-cutting themes that represent the main areas of consideration or influence on the thinking of the people involved in determining whether a firm or organization should relocate and, if so, where to. The resulting analysis finds that organizations adopt varying degrees of sophistication when making relocation decisions; small firms are more inclined to make decisions based on constrained information; larger organizations adopt a more complex approach. Regardless of firm size, key individuals exert considerable influence over the decision-making process and its outcome

A level playing ‘field’? A Bourdieusian analysis of the career aspirations of further education students on sports courses

There is currently a distinct dearth of research into how sports students’ career aspirations are formed during their post-compulsory education. This article, based on an ethnographic study of sport students in tertiary education, draws on data collected from two first-year cohorts (n = 34) on two different courses at a further education college in England. The study draws on ethnographic observations, and semi-structured group interviews, to examine in-depth the contrasting occupational perspectives emergent within these two groups of mainly working-class students, and how specific cultural practices affect students’ career aspirations. Utilising a Bourdieusian framework, the paper analyses the internalised, often latent cultural practices that impact upon these students’ diverse career aspirations. The hitherto under-researched dimension of inter-habitus interaction and also the application of doxa are outlined. The article reveals how the two student cohorts are situated within a complex field of relations, where struggles for legitimisation, academic accomplishment and numerous forms of lucrative capital become habituated. The study offers salient Bourdieusian-inspired insights into the career aspirations of these predominantly working-class students and the ways in which certain educational practices contribute to the production and reproduction of class inequalities

A Golf Programme for People with Severe and Enduring Mental Health Problems

This article reports a pioneering golf programme for people with severe and enduring mental health problems. Following a discussion of the problems and possibilities of golf as a form of physical activity for this group, we outline the structure, organisation, and ethos of the golf programme. Through an analysis of qualitative case study data collected during the programme, we discuss the response to the programme from service users and mental health professionals. We conclude by highlighting aspects of the programme which were critical to its success and offering suggestions for further initiatives in this area

Contribution of deformation to sea-ice mass balance: a case study from an N-ICE2015 storm

The fastest and most efficient process of gaining sea ice volume is through the mechanical redistribution of mass as a consequence of deformation events. During the ice growth season divergent motion produces leads where new ice grows thermodynamically, while convergent motion fractures the ice and either piles the resultant ice blocks into ridges or rafts one floe under the other. Here we present an exceptionally detailed airborne dataset from a 9km2 area of first and second year ice in the Transpolar Drift north of Svalbard that allowed us to estimate the redistribution of mass from an observed deformation event. To achieve this level of detail we analyzed changes in sea ice freeboard acquired from two airborne laser scanner surveys just before and right after a deformation event brought on by a passing low pressure system. A linear regression model based on divergence during this storm can explain 64% of freeboard variability. Over the survey region we estimated that about 1.3% of level sea ice volume was pressed together into deformed ice and the new ice formed in leads in a week after the deformation event would increase the sea ice volume by 0.5%. As the region is impacted by about 15 storms each winter a simple linear extrapolation would result in about 7% volume increase and 20% deformed ice fraction at the end of the seaso

Complexity of Risk: Mixed-Methods Approach to Understanding Youth Risk and Insecurity in Postconflict Settings

In settings of intergroup conflict, identifying contextually relevant risk factors for youth development is an important task. In Vukovar, Croatia, a city devastated during the war in former Yugoslavia, ethno-political tensions remain. The current study utilized a mixed-methods approach to identify two salient community-level risk factors (ethnic tension and general antisocial behavior) and related emotional insecurity responses (ethnic and nonethnic insecurity) among youth in Vukovar. In Study 1, focus group discussions (N = 66) with mothers, fathers, and adolescents of age 11 to 15 years old were analyzed using the constant comparative method, revealing two types of risk and insecurity responses. In Study 2, youth (N = 227, 58% male, M = 15.88, SD = 1.12 years) responded to quantitative scales developed from the focus groups, discriminate validity was demonstrated, and path analyses established predictive validity between each type of risk and insecurity. First, community ethnic tension (i.e., threats related to war/ethnic identity) significantly predicted ethnic insecurity for all youth (β = .41, p < .001). Second, experience with community antisocial behavior (i.e., general crime found in any context) predicted nonethnic community insecurity for girls (β = .32, p < .05) but not for boys. These findings are the first to show multiple forms of emotional insecurity at the community level; implications for future research are discussed

A phenomenological exploration of exercise mental toughness: perceptions of exercise leaders and regular exercisers

Although elite sport has provided an ideal context for exploring mental toughness (MT), currently, there is scant research examining how this construct might be equally applicable in exercise settings, where high rates of attrition have been reported. The present research, therefore, aimed to address this gap, and to understand and conceptualise exercise mental toughness (EMT) through in-depth phenomenological interviews with a range of exercise leaders and exercise participants. Seven qualified and experienced exercise leaders and seven regular and frequent exercisers from formal exercise environments (i.e. gym and fitness classes) were interviewed. Interviews were digitally recorded, transcribed verbatim and analysed independently by members of the interdisciplinary research team. Key themes were agreed and member checking was used to promote trustworthiness of interpretations. MT was recognisable in exercise settings, with 10 general dimensions found to be relatively consistent with conceptualisations derived from elite sport (e.g. commitment, focus, emotional control, etc.). Importantly, present findings reveal how mentally tough exercisers think and behave in exercise settings. Some negative consequences were also reported such as over-training and training with injuries. The article also discusses how components of EMT may be valuable in terms of exercise maintenance and relapse prevention during exercise behaviour change

Research to develop Spiritual Pedagogy, Awareness and Change

This is an Accepted Manuscript of an article published by Taylor & Francis in British Journal of Guidance and Counselling on 21-4-16, available online: http://dx.doi.org/10.1080/03069885.2016.1174976A co-operative inquiry group consisting of 8 counsellors met for 11 months to explore their experience of spirituality in their counselling training and in their work with clients (Swinton, 2010; 2015). The aim was to explore whether spirituality was absent from the process of counselling training, specifically to discover (1) how counsellors perceived and described their experience of spirituality in their training and (2) with a view to developing spiritual pedagogy; how spirituality could be incorporated into the training process of practitioner
