Ideas or Interests: Privacy in Electronic Communications

This article examines why the idea of privacy failed to structure policymaking in the case of the Electronic Communications Privacy Act (ECPA). Although the relatively quick passage of ECPA might appear to be a case of the politics of ideas, the model of interest group politics more simply explains policy making. The analysis of this case suggests several factors as important in establishing the conditions under which a politics of ideas will be realized.     

Russia’s Natural Resources in the World Economy: history,review and reassessment

Abstract

Russia’s role in the global economic system today, and the Soviet Union’s in the past, is dominated by the export of natural resources, particularly oil and gas. The rents earned from these exports are both a source of strength and weakness, as they link the fortunes of Russia’s domestic economy to the volatility of global resource markets. This paper returns to a major research project conducted through the offices of the Association of American Geographers that resulted in Soviet Natural Resources in the World Economy, published in 1983. The project was first conceived in the aftermath of the resource crisis in the 1970s and concluded in the early 1980s as the Soviet Union sought to increase resource exports to support a failing domestic economy. This paper examines the origins, evolution, and management of this seminal work and presents a re-reading of the book in a contemporary context. We develop some of the key themes of the original project and conclude that it has contemporary relevance, as a reliance upon the resource sector remains a defining characteristic of Russia’s political economy and continues to shape Russia’s role in the global economy. We find that the regional dimension that was so important in the original project remains critical as Russia seeks to extend the resource frontier into new regions in the Arctic and the East and, at the same time, reduce its reliance on European markets – that are both stagnant and hostile – by developing new markets in Asia.     

Pore pressure evolution and fluid flow during visco‐elastic single‐layer buckle folding

Pore pressure and fluid flow during the deformational history of geologic structures are directly influenced by tectonic deformation events. In this contribution, 2D plane strain finite element analysis is used to study the influence of different permeability distributions on the pore pressure field and associated flow regimes during the evolution of visco‐elastic single‐layer buckle folds. The buckling‐induced fluid flow regimes indicate that flow directions and, to a lesser degree, their magnitudes vary significantly throughout the deformation and as a function of the stratigraphic permeability distribution. The modelling results suggest that the volumetric strain and the permeability distribution significantly affect the resulting flow regime at different stages of fold development. For homogeneous permeability models (k > 10^?21 m²), low strain results in a mostly pervasive fluid flow regime and is in agreement with previous studies. For larger strain conditions, fluid focusing occurs in the buckling layer towards the top of the fold hinge. For low permeabilities (<10^?21 m²), local focused flow regimes inside the buckling layer emerge throughout the deformation history. For models featuring a low‐permeability layer embedded in a high‐permeability matrix or sandwiched between high‐permeability layers, focused flow regimes inside the folded layer result throughout the deformation history, but with significant differences in the flow vectors of the surrounding layers. Fluid flow vectors induced by the fold can result in different, even reversed, directions depending on the amount of strain. In summary, fluid flow regimes during single‐layer buckling can change from pervasive to focused and fluid flow vectors can be opposite at different strain levels, that is the flow vectors change significantly through time. Thus, a complete understanding of fluid flow regimes associated with single‐layer buckle folds requires consideration of the complete deformation history of the fold.
