BIOECONOMICS OF REGULATING NITRATES IN GROUNDWATER: TAXES, QUANTITY RESTRICTIONS, AND POLLUTION PERMITS

Soil specific, chance constrained, dynamic models of agricultural production and nitrate leaching are developed to assess the impacts of nitrogen fertilizer taxes, quantity restrictions on fertilizer or leachate, and leachate permits. A programming model uses the solutions of these bioeconomic models to determine regional impacts of the regulations.Land Economics/Use, Research Methods/ Statistical Methods,

David Bederman, Model Law Professor

It is an honor and privilege to contribute to this Issue of the Emory Law Journal remembering my longtime friend and colleague, David Bederman. It is right that we should do so, for David was the model law professor, excelling as an advocate, scholar, teacher, colleague, and friend. He set the standard for all of us

Periodic Atlas of the Metroscape: Lassoing Urban Sprawl

This issue\u27s atlas compares the metroscape with four other metropolitan areas (San Antonio, Columbus, Charlotte, and Orlando). Using 1990 and 2000 census block group data, density classifications were used to show patterns of urban (3 ,000+ persons/ sq.mi .), suburban (1 ,000 to 3,000 persons/sq.mi .), exurban (300 to 1,000 persons/sq .mi.) , and rural (/sq.mi.) growth. While the metroscape experienced significant population growth from 1990 to 2000, compared to the other four, it realized the smallest loss of rural lands and significantly less suburban and exurban style development as well. By comparison, Orlando - the other metro area in the sample using urban containment policies - realized significantly more outward development

Debunking the exurban myth: a comparison of suburban households

Journal ArticleAs American cities spill over their traditional boundaries into 'exurbia', the debate about whether this new growth is substantively different from what preceded is an important one. We disagree with the idea that the counterurbanization the United States is experiencing represents a dramatic break from previous growth patterns. Using parametric and nonparametric analysis, we examine whether or not the behavioral patterns and demographic characteristics of exurbanites differ from those of suburbanites. Is exurbanization really different from suburbanization and are exurbanites really different from suburbanites? Our research shows that the answer is no. Exurbia should not be defined separately from suburbia. Rather, the development on the metropolitan fringe is simply the latest incarnation of the continued suburbanization of American cities

Effectiveness of urban containment regimes in reducing exurban sprawl

Journal ArticleDuring the 1990s, the exurban landscape grew faster and added more people than urban, suburban, and rural landscapes. In many respects, exurbanization is the quintessential representation of urban sprawl and the problems it poses. More than 100 metropolitan areas across the US attempt to manage exurbanization through various forms of urban containment at regional or subregional scales. In this article, we assess the extent to which urban containment is effective in managing exurban sprawl in the 35 largest metropolitan areas in the US. Through simple cross-section analysis, we found that relative to metropolitan areas without urban containment, those pursuing "strong" containment efforts performed best in reducing exurbanization. Strong containment programs are those that direct urban development into areas defined by urban containment boundaries and restrict development outside the boundaries. Metropolitan areas with "natural" containment, i.e., where development is constrained because of oceans, mountains, public ownership, and water supply, did not perform as well but saw less exurbanization than noncontained metropolitan areas. Least effective relative to other forms of containment were metropolitan areas with weak containment efforts, principally because such approaches do not substantially restrict development outside containment boundaries. Strong urban containment appears to be effective in reigning in exurban sprawl but without apparently dampening population growth generally

The Three Uses of the Law: A Protestant Source of the Purposes of Criminal Punishment

In this article, we focus on the interaction of Anglo-American criminal law and Protestant theological doctrine. We argue (1) that the sixteenth-century Protestant theological doctrine of the uses of moral law provided a critical analogue, if not antecedent to the classic Anglo-American doctrine of the purposes of criminal law and punishment; and (2) that this theological doctrine provides important signposts to the development of a more integrated moral theory of criminal law and punishment in late twentieth century America. Part One of this Article sets out the theological doctrine of the civil, theological, and educational uses of the moral law, as formulated by sixteenth century Lutherans and Calvinists, and elaborated by later Protestant writers in England and America. Part Two analyzes the analogous deterrent, retributive, and rehabilitative purposes of criminal law, as articulated by early modem Anglo-American jurists and moralists, and explores the historical cross-fertilization between these theological and legal doctrines. Part Three reflects on contemporary American criminal law developments in light of this three uses doctrine

Alternative outlets for sustaining photosynthetic electron transport during dark-to-light transitions.

Environmental stresses dramatically impact the balance between the production of photosynthetically derived energetic electrons and Calvin-Benson-Bassham cycle (CBBC) activity; an imbalance promotes accumulation of reactive oxygen species and causes cell damage. Hence, photosynthetic organisms have developed several strategies to route electrons toward alternative outlets that allow for storage or harmless dissipation of their energy. In this work, we explore the activities of three essential outlets associated with Chlamydomonas reinhardtii photosynthetic electron transport: (i) reduction of O2 to H2O through flavodiiron proteins (FLVs) and (ii) plastid terminal oxidases (PTOX) and (iii) the synthesis of starch. Real-time measurements of O2 exchange have demonstrated that FLVs immediately engage during dark-to-light transitions, allowing electron transport when the CBBC is not fully activated. Under these conditions, we quantified maximal FLV activity and its overall capacity to direct photosynthetic electrons toward O2 reduction. However, when starch synthesis is compromised, a greater proportion of the electrons is directed toward O2 reduction through both the FLVs and PTOX, suggesting an important role for starch synthesis in priming/regulating CBBC and electron transport. Moreover, partitioning energized electrons between sustainable (starch; energetic electrons are recaptured) and nonsustainable (H2O; energetic electrons are not recaptured) outlets is part of the energy management strategy of photosynthetic organisms that allows them to cope with the fluctuating conditions encountered in nature. Finally, unmasking the repertoire and control of such energetic reactions offers new directions for rational redesign and optimization of photosynthesis to satisfy global demands for food and other resources
