  • Spatial planning as large-scale practical project : the problem of effective governance
  • The A. reflects upon the effectiveness of networked governance, using the collaborative spatial and environmental planning of Healey as a textbook example. He tries to answer the question of how effectiveness is guaranteed by strategic consensus

  • The effect on attribute prediction of location uncertainty in spatial data
  • The AA. propose a statistical model for incorporating location error into spatial data analysis. They investigate the effect of location error on the spatial lag, the covariance function, and optimal spatial linear prediction.

  • Effects of surface water storage by soil roughness on overland-flow generation
  • This study analyses effects of surface roughness on overland-flow by means of a model simulating depression filling, flow pathways and runoff generation. It examines the relevant characteristics of surface roughness using numerically generated
  • surfaces. Three surface descriptions are considered. First, the sensitivity of overland-flow triggering to surface correlation properties is addressed. Secondly, effects of the short-range correlation are studied. Thirdly, combined effects of random

  • Geographic and network neighbors : spillover effects of telecommunications infrastructure
  • The paper tests for spatial spillover effects of state-level telecommunications infrastructure investment on state output, using panel data for 48 U.S. states from 1970 to 1997. Findings indicate that a state benefits from its own telecommunications
  • infrastructure, but telecommunications investment by other states has a negative impact on its output growth path, and proximity amplifies this negative spillover effect.

  • The mean annual temperature at the top of permafrost, the TTOP model, and the effect of unfrozen water
  • The effect of unfrozen water content on the thermal properties of the ground is discussed in the context of the TTOP model. Numerical simulations of the thermal regime for a range of fine-grained soils are used to determine the effect of variable

  • Effects of club size in the provision of public goods. Network and congestion effects in the case of the French municipalities
  • The paper formalizes and measures the impact of club size on the quality of the public good provided to its members. Under a general framework the AA. describe various functional forms that allow either network or crowding effects. Mechanisms

  • Holocene lake-effect precipitation in northern Michigan
  • Holocene sediments from Nelson Lake, on Michigan's eastern Upper Peninsula, provide isotopic, pollen, and charcoal evidence for a two-step sequence of changes in moisture source and increased lake-effect precipitation during the late Holocene
