Oregon's land-use planning program is often cited as an exemplary approach to forest and farmland conservation, but analyses of its effectiveness are limited. This article examines Oregon's land-use planning program using detailed spatial data describing building densities in western Oregon. An empirical model describes changes in building densities on forest and agricultural lands from 1974 to...

This paper examines the effects of environmental zoning policies on lakefront land development, sorting, and economic welfare in a model where agents are heterogeneous in preferences and income. Agents consume lakefront amenities that are endogenous to development and the sorting process yields lakes which differ by amenities and frontage prices. Our findings include the following: i) lakes bec...

Large earthquakes occur in rocks undergoing high-pressure/low-temperature metamorphism during subduction. Rhythmic major-element zoning in garnet is a common product of such metamorphism, and one that must record a fundamental subduction process. We argue that rhythmic major-element zoning in subduction zone garnets from the Franciscan Complex, California, developed in response to growth-dissol...

Observation of social and economic trends (falling population in the inner city of Paris, increased commuter flows between the centre and the suburbs, and demand for local ticket prices) has led the Syndicat des Transports Parisiens (STP, the Paris transport authority) to re -examine the ticket price system as it is today. Reform of this system will involve a great many stakeholders in the tran...

Introduction: QUE 94201 (QUE) is a basaltic shergottite containing subequal amounts of pyroxene and plagioclase, the latter having been converted to maskelynite by shock (Fig. 1) [e.g., 1-3]. Pyroxene occurs as elongate subhedral to euhedral grains up to several mm in length. It has extensive and complex zoning (Fig 1). Typical grains have Mg-rich pigeonite cores mantled by Mg-rich augite, whic...

Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In this study, we use a linear programming model to endogenously allocate forest land to management inte...

In this paper, artificial neural networks (ANN) are proposed to classify and establish zoning faults (single-phase, bi-phase and tri-phase short circuits) in primary distribution systems. The proposed classification and zoning models are oriented toward the stochastic tracking of failures via emergency brigades. This work, instead of training a big ANN model, proposes to decompose the problem i...

The idea of using law to change the built environment in ways that reduce opportunities to commit crimes has a long history. Unfortunately, this idea has received relatively little attention in the legal academy and only limited rigorous empirical scrutiny. In this Article, we review the considerable literature on the relationship between zoning, the built environment, and crime. We then report...

A desktop Geographic Information Systems (GIS) for Geotechnical Information Management system has recently been developed to assist geo-technical managers, planners through flexible application with all common desktop GIS functionalities and customized tools like Borehole Viewer and Stripchart to relate alignments and cross-sections to a specific location and/or region on the map, and create th...
