Holding eternity in an hour: A practical exploration of the arts in the health care of older people with dementia

This project involved creative artists working with older people with dementia and staff from two Belfast Health and Social Care Trust supported housing centres in a mixed programme of dance, painting, music and drama which culminated in an open workshop with relatives and friends of the tenants. The study steered away from traditional medical models of art/music/dance therapy where the participant is perceived as a ‘patient’ in favour of identifying the participant as a ‘student’ who avails of a life-long learning experience. A key premise was that access to the arts is a human right, especially in the context of advancing age and cognitive impairment. . According to one the tenants of Mullan Mews, the project served to ‘awaken - or reawaken - folk with dementia to the endless vista of possibility already in their lives if they will only look for it’. A phenomenographic analysis of video data generated by the project emphasises the importance of the individual experiences of participants in the programme. The evidence from these storylines gained strength from the development of a documentary-style film text that has proved successful in capturing and translating the live experience of the project participants into a supportive text that goes beyond the written word.

Evidencing reflective practice in social work education: Theoretical uncertainties and practical challenges

Reflective practice has become an increasingly influential idea in social work education and, in the UK context, it has recently been acknowledged as key to ensuring that social workers are better equipped to engage in complex decision making and effective practice. However, there remains a lack of clarity about how this concept is defined and operationalised in teaching and learning and there has been little systematic empirical examination of its utility in facilitating professional development. Drawing on research with undergraduates at Queen's University Belfast, this paper aims to develop understanding of students' experience of reflective practice. The results suggest that agency systems that have become over-reliant on rules and procedures present formidable obstacles to learning both at an individual and at an organisational level. The paper argues that the relationship between how reflective practice is taught and how it is enacted in practice needs to be better understood if such obstacles are to be overcome. The paper concludes by considering the implications of the findings for developing reflective practice in social work education and practice and highlights the challenges that need to be addressed if reflection and critical thinking are to become more firmly embedded within agency systems and practice cultures.

‘Papers from ‘A Symposium with Professor Roger Brownsword: Super-stewardship in the Context of Public Health’’

This special issue seeks to engage the term 'stewardship' and the practical and theoretical work around it, both of which are destined to remain items of unfinished business as governance struggles to keep up and connect with its fast moving technological and societal targets. While this special issue is testament to that observation, it also helps to foster much needed scholarly discussion and critique – and to ensure this field is not unwittingly formed and deployed by and as a legitimating support for governance, but rather opened up, elaborated and contested. The articles provide innovative insights and food for thought on the conception and legal-political practice and potential of stewardship and ‘super-stewardship’ in national, supranational and international settings.

Practical Spectrum Aggregation for Secondary Networks with Imperfect Sensing

We investigate a collision-sensitive secondary network that intends to opportunistically aggregate and utilize spectrum of a primary network to achieve higher data rates. In opportunistic spectrum access with imperfect sensing of idle primary spectrum, secondary transmission can collide with primary transmission. When the secondary network aggregates more channels in the presence of the imperfect sensing, collisions could occur more often, limiting the performance obtained by spectrum aggregation. In this context, we aim to address a fundamental query, that is, how much spectrum aggregation is worthy with imperfect sensing. For collision occurrence, we focus on two different types of collision: one is imposed by asynchronous transmission; and the other by imperfect spectrum sensing. The collision probability expression has been derived in closed-form with various secondary network parameters: primary traffic load, secondary user transmission parameters, spectrum sensing errors, and the number of aggregated sub-channels. In addition, the impact of spectrum aggregation on data rate is analysed under the constraint of collision probability. Then, we solve an optimal spectrum aggregation problem and propose the dynamic spectrum aggregation approach to increase the data rate subject to practical collision constraints. Our simulation results show clearly that the proposed approach outperforms the benchmark that passively aggregates sub-channels with lack of collision awareness.
