The future of distance education : reformed, scrapped or recycled

A mass of under-educated people, an expanding population, major global crises and an expanding knowledge economy all combine to sustain a massive demand for basic, further, higher, continuing and lifelong education.This demand cannot be met solely in the world’s classrooms; even if there were enough classrooms, many people will be unwilling or unable to attend them to learn. In this sense, distance education is essential for the future, but the fluidity around educational terms and practices means that it is also quite possible that ‘distance education’—the term and its history—will be towed to the scrap yard for many of its useful parts to be recycled. This chapter considers three key elements of distance education—technology, students and educational institutions—and the educational possibilities that surround them by reflection on past and present changes. The future of distance education is intimately connected to broader social, economic and cultural changes. These changes are strongly influenced by the ‘disruptive’ technologies, demographic transformations in the nature of distance learners and the pressures of global techno-capitalism on educational institutions.

The impacts of recycled water on Great Western vineyard soils

Recycled water has facilitated expansion of viticulture in Great Western, Victoria. The recycled water is of medium salinity, and has high concentrations of nutrients and sodium. Irrigation has resulted in increased topsoil EC, pH, and ESP. Laboratory studies identified spatially heterogeneous soils which present a risk of groundwater and offsite contamination.

American beauty recycled : the celebrity machine

This work examines the 'machine' of celebrity suggesting that the value assigned to celebrity and the function of celebrity n our society has to do with surplus desire and fluid identity. This work gtakes the video within the movie American Beauty and reframes i as an installation with gold leaf commenting on the ephemeral and trahs-lie, throw-away nature of celebrity and the way in which celebration can be extracted from the lottery of celebrity production.

Was monochloramine responsible for widespread lettuce crop failures at a major recycled water irrigation scheme?

In 2008, vegetable growers observed stunted lettuce plants showing signs of chlorosis and wilting. It was suspected that monochloramine in the recycled water used for irrigation, in combination with extreme environmental conditions (high irrigation water salinity and extreme heat), was responsible for these crop failures. A series of glasshouse studies was conducted to evaluate the impact of monochloramine concentration alone on iceberg lettuce seedlings, as well as in combination with high salinity and hot ambient temperatures. Monochloramine concentrations up to 9 and 15 mg L−1 Cl2 for continuous and initial irrigation only, respectively, did not affect the weight of iceberg lettuce heads (p > 0.05), while the combination of monochloramine (4–5 mg L−1 Cl2) and salinity (3,500 μS cm−1) did not significantly affect harvest measurements (p > 0.05). We therefore conclude that it is unlikely that monochloramine was responsible for the observed crop failures.
