Trans‐border European networking: Shifts in corporate strategy?

The disappearance of man‐made borders and the need for increased international cooperation seem to prelude a removal of unnecessary obstacles between actors in different countries. This article is concerned with the relationship between political borders, economic development of border regions and networking of companies located there. It presents a ‘state of the art’ of research on border region development and trans‐border networking by companies. Based upon this research, the article concludes with a discussion on conditions that influence the emergence of new corporate networking in border regions, including effective policy action.     

Spatial Diffusion of the HIV/AIDS Epidemic: Modeling Implications and Case Study of AIDS Incidence in Ohio

This paper extends a compartmental epidemiological model for HIV transmission and AIDS incidence to include hierarchical and expansion spatial diffusion. An implication of the resultant model is that hierarchical diffusion causes the large infection growth rates of densely populated areas at the top of the central places hierarchy to “chain” down and dominate small local growth rates during the exponential-growth phase of the epidemic. Also, hierarchical diffusion causes a high transient growth rate in the first few years of a local epidemic. The spatial compartmental model fits observed AIDS incidence spatial diffusion patterns in Ohio reasonably well.     

Peace Protest and Policy

The tremendous fluctuations in public mobilization against United States nuclear weapons policy, a relatively stable policy over four decades, present a difficult riddle to social scientists. Since the dawn of the nuclear age small groups of activists have consistently protested both the content of United States national security policy and the process by which it is made. Only occasionally, however, has this protest spread beyond a handful of relatively marginal groups, generated substantial public support, and reached mainstream political institutions. This article examines the political cycles of peace movement engagement and quiescence, and their relation to external political context, particularly public policy. I begin with a brief review of the relevant literature on the origins of the movements, noting parallels in the study of interest groups. Building on recent literature on political opportunity structure. I suggest a theoretical framework which emphasizes the interaction between activists choices and political context. I then describe the cycles of peace movement activism and quiescence on nuclear weapons issues in the United States using mass media sources to delineate periods of mobilization. I outline a number of policy variables which may help explain protest mobilization. My conclusions address the importance of policy and political context in explaining movement cycles and the potential influence of protest movements on policy.     

Planning in the 1990s: An international agenda

This paper, originally presented to the AESOP‐ACSP joint conference in Oxford in 1991, stresses that both in Europe and in the US, there is a major difference for planning in the switch from boom to recession. During the 1990s a major challenge will be to find new ways of public‐private partnership in financing new urban infrastructure at a time when developer contributions — a major innovation of the 1980s — have dried up. This particularly applies to the European high‐speed train system — one critical element of which will run through the East Thames Corridor, one of Britain's major urban developments in the coming years. In the US, planners are likely to remain more locally focused, less internationally concerned, than in a Europe in which national barriers are rapidly eroding.
