School Broadcasting in the United Kingdom: An Exploratory History

In the United Kingdom, television for schools is 50 years old in 2007. The anniversary provides a reason to undertake an exploratory history of school broadcasting, an area that has received very little attention from historians of British education. The first part of this article examines the origins of school radio broadcasting, focusing especially upon the pioneering work of Mary Somerville, who served as the BBC’s first Director of School Broadcasting from 1929 to 1947. It is then argued that school broadcasting had a ‘good war’, enhancing its international reputation and sense of public value between 1939 and 1945. Following the conclusion of hostilities, there were high expectations that television for schools would become quickly established, but financial, technical and other practical impediments delayed the launch of services until 1957. By that time, commercial television had emerged as a rival to the BBC and it was an ITV company, Associated-Rediffusion, rather than the BBC, which won the race to broadcast the first television programmes for schools. Some significant technological and marketled changes since the 1980s are noted, but the conclusion states that the reputation of British school broadcasting remains high at the beginning of the twenty-first century

Do we need clinical trials to test the ability of transdermal HRT to prevent coronary heart disease?

Postmenopausal hormone replacement therapy (HRT) with oral oestrogen was predicted to reduce coronary heart disease (CHD) risk by 50%. Randomized controlled trials show no such benefit, however, pointing instead to an initial increase in CHD events. Although the cardiovascular effects of transdermal HRT are largely unknown, improvements in arterial function are maintained when oestrogen is administered transdermally. Transdermal HRT also avoids the increased plasma levels of C-reactive protein (CRP) that are seen with oral HRT. However, the clinical significance of this general reduction in hepatic over-synthesis of plasma proteins is difficult to assess. Nevertheless, the available evidence on transdermal HRT appears to justify a formal clinical trial

Harnessing Technology: new modes of technology-enhanced learning: opportunities and challenges

A report commissioned by Becta to explore the potential impact on education, staff and learners of new modes of technology enhanced learning, envisaged as becoming available in subsequent years. A generative framework, developed by the researchers is described, which was used as an analytical tool to relate the possibilities of the technology described to learning and teaching activities. This report is part of the curriculum and pedagogy strand of Becta's programme of managed research in support of the development of Harnessing Technology: Next Generation Learning 2008-14. A system-wide strategy for technology in education and skills. Between April 2008 and March 2009, the project carried out research, in three iterative phases, into the future of learning with technology. The research has drawn from, and aims to inform, all UK education sectors

Conclusion: Rethinking African Governance and Development

This article draws together the main strands of argument being developed by the Africa Power and Politics Programme (APPP), as reflected in this IDS Bulletin. The central question is what kinds of governance arrangements work better to support the provision of the public goods that are essential to sustained and inclusive development in Africa. Evidence at local, sectoral and national levels is pointing to the overall conclusion that what works is often a ‘practical hybrid’, combining authoritative coordination with local problem?solving and constructive borrowing from local cultural repertoires. Consistent with the general idea of ‘going with the grain’, we find that the most likely source of the necessary vertical discipline is a developmental form of neo?patrimonialism, not ‘good governance’, as currently conceived. Similarly, local collective action to address bottlenecks in public goods provision is seldom enhanced by standard donor and NGO approaches to citizen or client empowerment

Timing, frequency and environmental conditions associated with mainstem-tributary movement by a lowland river fish, golden perch (Macquaria ambigua)

Tributary and mainstem connections represent important links for the movement of fish and other biota throughout river networks. We investigated the timing, frequency and environmental conditions associated with movements by adult golden perch (Macquaria ambigua) between the mainstem of the mid-Murray River and a tributary, the Goulburn River, in south-eastern Australia, using acoustic telemetry over four years (2007–2011). Fish were tagged and released in autumn 2007–2009 in the mid-Murray (n = 42) and lower Goulburn (n = 37) rivers within 3–6 km of the mid-Murray-lower Goulburn junction. 38% of tagged fish undertook mainstem–tributary movements, characterised mostly by temporary occupation followed by return of fish to the original capture river. Approximately 10% of tagged fish exhibited longer-term shifts between the mainstem and tributary. Movement of fish from the tributary into the mainstem occurred primarily during the spawning season and in some years coincided with the presence of golden perch eggs/larvae in drift samples in the mainstem. Many of the tributary-to-mainstem movements occurred during or soon after changes in flow. The movements of fish from the mainstem into the tributary were irregular and did not appear to be associated with spawning. The findings show that golden perch moved freely across the mainstem–tributary interface. This demonstrates the need to consider the spatial, behavioural and demographic interdependencies of aquatic fauna across geographic management units such as rivers
