URBAN SPRAWL AND OBESITY

In the U.S., urban sprawl and the rise in obesity rates have been two powerful trends during the latter half of the 20th century. Previous empirical work has found that obesity rates are influenced by labor market outcomes that are fundamentally shaped by the spatial pattern of developed land. We examine these potential linkages in an urban spatial model augmented to include time allocation and weight. Residents maximize utility defined over housing, weight, and food subject to a fixed time budget allocated to commuting, calorie expenditure, and work. We examine how weight is affected by commuting distance, food prices, and the rate of calorie expenditure; how a reduction in transportation costs affects weight throughout the city; and how initial weight affects location decisions. We identify, and explore the significance of, the conditions under which weight gain is associated with common features of sprawl.Food Consumption/Nutrition/Food Safety,

PUBLIC CONSERVATION LAND AND EMPLOYMENT GROWTH IN THE NORTHERN FOREST REGION

As with many environmental issues, debates about increasing public conservation lands in the Northern Forest region frequently center on a perceived tradeoff between jobs and the environment. In particular, opponents of conservation lands often argue that employment will decline significantly when land is diverted from commodity-oriented uses such as wood products production. To evaluate this claim, we estimate a model of simultaneous employment and net migration growth using data on the 92 non-metropolitan counties comprising the region. Growth in employment and net migration are measured over the period 1990 to 1997 and the set of exogenous variables includes the 1990 share of the county land base in public conservation uses. We find that net migration rates were systematically higher in counties with more conservation lands, but the effects are relatively small. Public conservation lands were found to have no systematic effect on employment growth over the 1990 to 1997 period. Two extensions are considered. We examine the separate effects of preservationist and multiple-use lands. We also identify a "natural experiment" involving changes in national forest management that allows us to estimate the effects of diverting private forestland to public conservation uses. Our central conclusions are that existing public conservation lands have a positive, but small, effect on employment and migration in the Northern Forest region and that, over the range of our data, employment and migration are unlikely to be affected by timber harvest reductions resulting from the establishment of new conservation lands.Labor and Human Capital, Land Economics/Use,

Local Employment Growth, Migration, and Public Land Policy: Evidence from the Northwest Forest Plan

Debates over protecting public land reveal two views. Some argue protection reduces commodity production, reducing local employment and increasing out-migration. Others contend protection produces amenities that support job growth and attract migrants. We test these competing views for the Northwest Forest Plan (NWFP), which reallocated 11 million acres of federal land from timber production to protecting old-growth forest species. We find evidence that land protection directly reduced local employment growth and increased net migration. The total negative effect on employment was offset only slightly by positive migration-driven effects. Employment losses were concentrated in metropolitan counties, but percentage losses were higher in rural counties.amenities, employment growth, migration, Northwest Forest Plan, oldgrowth forests, public land management, Community/Rural/Urban Development, Land Economics/Use,

The criterion-related validity of the Northwick Park Dependency Score as a generic nursing dependency instrument for different rehabilitation patient groups

Objective: To investigate the criterion or concurrent validity of the Northwick Park Dependency Score (NPDS) for determining nursing dependence in different rehabilitation groups, with the Barthel Index (BI) and the Care Dependency Scale (C D S).Design: Cross-sectional study.Setting: Centre for Rehabilitation of the University Medical Center Groningen, The Netherlands.Subjects: Patients after stroke, spinal cord injury, multitrauma, head injury, amputation, rheumatoid arthritis, diabetes mellitus, lung diseases, tuberculosis and coronary artery disease. One hundred and fifty-four patients were included.Measures: The Northwick Park Dependency Score (NPDS), the Barthel Index (BI) and the Care Dependency Scale (CDS).Results: The correlation (rho) between the NPDS and the BI for all groups was - 0.87-1 R-2 = 0.76 (n = 154). Per patient group rho varied from - 0.70 (R-2 = 0.49) to - 0.93 (R-2 = 0.86). The overall correlation between the NPDS and CDS was larger than the criterion of rho = 0.60 (r=- 0.74; R-2 = 0.55) but was &lt;0.60 in the rheumatoid arthritis and tuberculosis group. The overall correlation between BI and CDS exceeded the criterion (r = 0.75; R-2 = 0.56).Conclusions: The NPDS is a generic nursing dependency instrument that can be used as a valid measure across various patient groups in rehabilitation.</p
