Design or decline-a national emergency? 1

The author draws attention to the demise of British manufacturing and stresses the importance of design. It is made clear that unless there is a change in attitude to the role of the professional engineer Britain's manufacturing base will continue to decline with markets steadily being lost to countries with a better motivated workforce     

Developing the untapped wealth of Britain's 'Celtic Fringe': Water engineering and the Welsh landscape, 1870-1960

This paper focuses on the development of water engineering schemes in Wales in the late 19th and 20th centuries, concentrating mainly on water-supply schemes promoted by large English municipalities such as Birmingham and Liverpool, but also discussing hydro-electricity. It is argued that the first water engineering projects in Wales were informed by certain perceptions of the Welsh landscape and wider discourses regarding Britain's 'Celtic Fringe', and that such concepts were used to promote ideas of water purity. Ideas of 'progress' and 'modernity' surrounding the changing of the landscape through water works are analysed, and how such notions were challenged in the 20th century is explored, particularly from conservationist and nationalist perspectives. In the second half of the 20th century, it is argued, a paradox emerges, whereby different ways of seeing or perceiving the landscape of Wales led to a divergence in the political dynamics surrounding water-supply projects and hydro-electric schemes.

Preventive measures to reduce bioaerosol exposure during refuse collection: results of field studies in the real-life situation

The aim of the present research project was to investigate and evaluate technical and organisational measures targeted at bioaerosol reduction during the refuse collection and to determine the exposure of refuse collectors to dust, fungi and endotoxins in an on-the-job situation with different vehicle technologies and states of hygiene. The following technical factors were found to influence the bioaerosol concentration at the refuse collector's workplace: compaction method, lifting device control, rave rail height, hopper depth, design of intake area and dust interception. For instance, notably higher total fungal counts were recorded with rotating drum compaction than with packer plate compaction. A hinged lid closure at the lifting device in conjunction with a suction unit induced a positive effect. In addition, the automatic lifting system had a positive influence on rear-end loaders, as did loading operation control from the closed driver's cab on side loaders. Regular internal and external high-pressure cleaning of the lifting device at intervals of not more than 14 days is recommended as a basic rule for vehicle hygiene.

Colonial Settlers and the Metropole: racial discourse in the early 19th-century Cape Colony, Australia and New Zealand

The ways that British settlers in South Africa, Australia and New Zealand, particularly those engaged in the extension of commercial sheep farming, constructed a certain discourse of colonialism during the first half of the 19th century are discussed. It is argued that this discourse was formulated, at least in part, in opposition to that of humanitarians within each colony and in Britain, who challenged settler capitalist practices on the fringes of Britain's expanding empire. Representations of a civilizing impact on the landscape were one component of the new racialized understandings and identities that settlers at each site constructed in their defence. Through attention to three colonial sites and their relations with each other and with the metropole, it is aimed to highlight the ways in which discourses of colonial landscapes and their inhabitants travelled across an imperial terrain.
