Calculating Property Relations

Calculating Property Relations

Combining theories of calculation and property relations and using an array of archival sources, this book focuses on the building and decommissioning of state-owned defense factories in World War II-era Chicago. Robert Lewis's rich trove of material--drawn from research on more than six hundred federally funded wartime industrial sites in metropolitan Chicago--supports three major conclusions. First, the relationship of the key institutions of the military-industrial complex was refashioned by their calculative actions on industrial property. The imperatives of war forced the federal state and the military to become involved in industrial matters in an entirely new manner. Second, federal and military investment in defense factories had an enormous effect on the industrial geography of metropolitan Chicago. The channeling of huge lumps of industrial capital into sprawling plants on the urban fringe had a decisive impact on the metropolitan geographies of manufacturing. Third, the success of industrial mobilization was made possible through the multi-scale relations of national and locational interaction. National policy could only be realized by the placing of these relations at the local level. Throughout, Lewis shows how the interests of developers, factory engineers, corporate executives, politicians, unions, and the working class were intimately bound up with industrial space. Offering a local perspective on a city permanently shaped by national events, this book provides a richer understanding of the dynamics of wartime mobilization, the calculative actions of political and business leaders, the social relations of property, the working of state-industry relations, and the making of industrial space.

Structure-Property Relationships in Surface-Modified Ceramics

The use of ion beams for the modification of the structure and properties of the near-surface region of ceramics began in earnest in the early 19805. Since the mechanical properties of such materials are dominated by surface flaws and the surface stress state, the use of surface modification tech niques would appear to be an obvious application. As is often the case in research and development, most of the initial studies can be characterized as cataloging the response of various ceramic materials to a range of ion beam treatments. The systematic study of material and ion beam parameters is well underway and we are now designing experiments to provide specific information about the processing parameter - structure-property rela tionships. This NATO-Advanced Study Institute was convened in order to assess our current state of knowledge in this field, to identify opportunities and needs for further research, and to identify the potential of such processes for technological application. It became apparent that this class of inorganic compounds, loosely termed ceramics, presents many challenges to the understanding of ion-solid inter actions, the relationships among ion-beam parameters, materials parameters, and the resulting structures, as well as relationships between structure and properties. In many instances, this understanding will represent a major extension of that learned from the study of metals and semiconductors.
