The interaction of polyacid-modified composite resins ("compomers") with aqueous fluoride solutions

OBJECTIVE: The aim of this study was to investigate how the release of fluoride from two compomers and a fluoridated composite resin was affected by exposure to KF solution. MATERIAL AND METHODS: Two compomers (Dyract AP and Compoglass F) and one fluoridated composite (Wave) were prepared as discs (6 mm diameter and 2 mm thick), curing with a standard dental lamp. They were then stored in either water or 0.5% KF for 1 week, followed by placement in water for periods of 1 week up to 5 weeks total. Fluoride was determined with and without TISAB (to allow complexed and decomplexed fluoride to be determined), and other ion release (Na, Ca, Al, Si, P) was determined by ICP-OES. RESULTS: Specimens were found not to take up fluoride from 100 ppm KF solution in 24 h, but to release additional fluoride when stored for up to five weeks. Compomers released more fluoride cumulatively following exposure to KF solution (p<0.001), all of which was decomplexed, though initial (1 week) values were not statistically significant for Dyract AP. Other ions showed no variations in release over 1 week, regardless of whether the specimens were exposed to KF. Unlike the compomers, Wave showed no change in fluoride release as a result of exposure to KF. CONCLUSIONS: Compomers are affected by KF solution, and release more fluoride (but not other ions) after exposure than if stored in water.

Creating a suitable and successful solution for the integration of podcasting and vidcasting in a higher education e-learning environment

A small research project is currently taking place within a department of the University of Greenwich. The project involves using current technology (Apple’s xServe, iPhones, iPod touch, Podcast Producer application and some 3rd party capture software) with the intention to provide a solution for quick and simple podcasting. This paper also aims to investigate the use of podcasting to help promote and extend the e-learning provision within the school. In short this project aims to justify the use of podcasting as a teaching and learning tool to help enhance student learning while identifying the most appropriate manner to integrate podcasting within an e-learning environment.

'Bowing from the heart': an investigation into discourses of professionalism and the work of caring for students in further education

Since their incorporation in 1993, further education (FE) colleges in England have been responsible for their own staffing and, faced with funding constraints as well as recruitment and retention targets, some have introduced a new category of staff referred to here as 'learning support workers' (LSWs). Though their employment conditions and specific duties vary considerably, LSWs' work often includes providing individual care for students. In this small-scale study, using semi-structured interviews, the perceptions of some teachers and LSWs about the nature of their relationships with each other and with students are investigated. The study is set broadly in the context of debates about the impact of public sector reform on FE colleges and teachers. A discourse analysis approach is adopted in discussion of the data. The authors conclude that although they are differently positioned in relation to traditional discourses of professionalism, both teachers and LSWs are perceived to be carrying out what Hochschild termed 'emotional labour'. The contradictory nature of emotional labour is also highlighted. Some of the implications of employing a new group of workers in FE are discussed.

South East London Palliative and End of Life Care Education and Training Strategy: Meeting the Education and Training Needs of the Health & Social Care Workforce Involved in the Care of Patients and Carers at the End of Life.

EXECUTIVE SUMMARY Aims 1. The aims of this strategy are • to ensure that a full range of education and training related to the adult end of life care pathway is available across South East London to meet the needs of our health and social care workforce • to enable those responsible for end of life care education and training commissioning to procure comprehensively from a full range of education providers in a systematic and strategic manner. Background 2. The work that underpins this strategy was begun by the South East London Cancer Network via its Palliative and End of Life Care Coordinating Group and then developed by way of the Marie Curie Delivering Choice Programme’s Education and Training work stream.

‘Nothing will prevent me from doing a good job’. The professionalisation of part-time teaching staff in further and adult education

Approximately 85,000 part-time teaching staff working in further education (FE) and adult and community learning (ACL) are often seen as ‘a problem’. The intrinsic ‘part-timeness’ of these staff tends to marginalise them: they remain under-recognised and largely unsupported. Yet this picture is over-simplified. This article examines how part-time staff make creative use of professional autonomy and agency to mitigate problematic ‘casual employment’ conditions, reporting on results from Learning and Skills Development Agency-sponsored research (2002–2006) with 700 part-time staff in the learning and skills sector. The question of agency was reported as a key factor in part-time employment. Change is necessary for the professional agency of part-timers to be harnessed as the sector responds to ambitious sectoral ‘improvement’ agendas following the Foster Report and FE White Paper. Enhanced professionalisation for part-time staff needs greater recognition and inclusion in change agendas.
