Maps an apartheid-era Zulu Radio station as it grew to become one of the largest stations in Africa, countering censorship and propaganda.
Zulu Radio in South Africa is one of the most far-reaching and influential media in the region, currently attracting around 6.67 million listeners daily. While the public and political role of radio is well-established, what is less understood is how it has shaped culture by allowing listeners to negotiate modern identities and fast-changing lifestyles. Liz Gunner explores how understandings of the self, family, and social roles were shaped through this medium of voice and mediated sound. Radio was the unseen literature of the auditory, the drama of the airwaves, and thus became a conduit for many talents squeezed aside by apartheid repression. Besides Winnie Mahlangu and K. E. Masinga, among other talents, the exiles Lewis Nkosi and Bloke Modisane made a network of identities and conversations which stretched from the heart of Harlem to the American South, drawing together the threads of activism and creativity from both Black America and the African continent at a critical moment of late empire.
It is now possible to determine concentrations of trace constituents and pollutants in the lower atmosphere from space, a development which heralds a new era for tropospheric chemistry. The authors describe how to develop and validate methods for determining tropospheric trace constituents from satellite data, to encourage the use of these data by atmospheric chemists, and to explore the undoubted synergism which will develop between satellite and ground-based measurements, and will eventually give rise to a permanent observation system for the troposphere. The book comprises several comprehensive overviews, prepared by acknowledged experts in the field, together with a series of individual reports from investigators whose work represents the cutting edge of the subject. A variety of results, giving global distributions of several species and their modelling are reported. Most results stem from ESA satellite data, but there is also an account of the North American work in this field which has mainly concentrated on global distributions of ozone. It is fair to say that the field, as it develops, will revolutionize the way in which atmospheric chemistry is done. This timely book provides a good introduction for anyone with an interest in the future of the troposphere.
Containing useful information sources for the management of natural resources, this comprehensive text covers a large range of spatial resolutions and spectral characteristics. The book deals with the data sources and their physical interpretation, as well as processing techniques, such as visual interpretation and automated classifications, textural and structural processing and photogrammetry. There is a section on accuracy assessment and various applications relating to crops, grasslands, soils, landscapes, mines and coasts. The CD-ROM contains software and image data sets explaining the statistical methods of reference and contains a light version of the TeraVue software enabling the reader to compute the different processing spatial data.
