Environmental Risk and Uncertainty: Insights from Yucca Mountain

Abstract This study examines the effects of the risk from transporting high–level radioactive waste to the proposed Yucca Mountain repository on housing location decisions in Southern Nevada. Using data from a survey of southern Nevada households, we develop a model–based subjective risk estimate for each household. We then explore different factors that may influence the household's location decisions if the proposed transportation route is ultimately chosen for nuclear waste transport. We extend the conventional expected utility model to allow for uncertainty surrounding the actual risks borne by the household. Finally, we examine the impact of federal government compensation on households' location decisions. The findings indicate that residents currently living near the proposed transportation route express subjective risk estimates much larger than those reported by the Department of Energy. In general, households that are uncertain about the future risks are more likely to relocate than those expressing certainty. When everything is considered, the model predicts that between one and three percent of households living near the transportation route are likely to relocate. Compensation can influence some households to remain at their present location and bear the transport risk.     

Head Start's Comparative Advantage: Myth or Reality?

In recent years, Head Start's prominent role in preparing low‐income 4‐year‐olds for school has been affected by rapid growth in state‐funded pre‐K programs, some of which are based in public schools. This has led to questions about the comparative advantages of these two approaches to early education. An analysis of data from Tulsa, Oklahoma, indicates that the school‐based pre‐K program is more effective in improving early literacy outcomes, while Head Start is more effective in improving health outcomes. The two programs are comparable with regard to early math learning. Social–emotional effects are more subtle, but the school‐based pre‐K program has demonstrable positive effects, while the Head Start program does not.     

Geographic and Historical Observations on the Future of a Federal Russia

A paper assessing prospects for the future of federalism in Russia investigates geographic and other factors that historically have either promoted or inhibited the unity of the Russian state. Among the major factors complicating the process of forging a new federal relationship among Russia's central government, republics, and oblast-level units, the paper focuses on the question of the Russian state's legitimacy, the only partial character of democratization, limited experience with constitutional federalism, and contradictions between individual and ethnic rights. 2 tables, 19 references.     

Adapting the roman alphabet for writing Old English: evidence from coin epigraphy and single‐sheet charters

Single‐sheet charters and coin epigraphy provide valuable evidence for the development of representations of the Old English dental fricative in the seventh and eighth centuries. This evidence indicates differing Kentish and Mercian practices up to the 780s, when scribes in both areas rapidly adopt <ð> to represent this sound. In Kent, occasional experimentation with this character from perhaps as early as the reign of Eadbald (616–40 ad ) may suggest a lengthy period of gradual adoption prior to the rapid increase. Mercian practice instead shows an abrupt adoption, which is perhaps the result of reform according to external (perhaps Kentish) models.     

The compendium of European spatial planning systems

This paper sets out the context for the production of a European planning systems compendium, which will provide an authoritative and accessible source of information about systems and policies across the European Union.
