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.     

Assessing the reliability of pRIA for identifying ancient proteins from archaeological contexts

The use of immunological techniques for identifying the origin of proteins and inferring foodstuffs exploited by prehistoric occupations has been conducted for several decades. Cases of experimental laboratory and archaeological studies have shown the potential of these techniques for reliable results. However, very few of these case studies employ archaeological sites that have excellent preservation and high-resolution spatial contexts between identifiable faunal remains, features, and stone tools. We present an assessment of the identification reliability of one immunological technique, protein radioimmunoassay (pRIA), using faunal remains and stone tools from two sites from arctic and subarctic contexts. The results of this research indicate that, even in contexts with excellent preservation, the identifications produced by the pRIA technique are subject to misidentification and cross-reactions due to diagenetic alteration of proteins. We propose a higher minimum reaction value (percent binding of labeled antibody) that mitigates these effects, and renders the pRIA results more reliable for ancient, poorly preserved organic remains.     

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.     

Slum clearance, privatization and residualization: the practices and politics of council housing in mid-twentieth-century England

This article contributes to a growing literature on working-class suburbanization by arguing that both the residualization and privatization of council housing need to be properly historicized. This case study of housing policy in the borough of Brighton demonstrates that council house sales between the 1950s and 1970s were important in the residualization of inter-war estates well before the 'right to buy' legislation of the 1980s. Concerns about excessively affluent tenants can also be traced to the inter-war period, although it was not until the late 1950s that local Conservatives sought to push affluent council tenants into owner occupation via capping incomes and encouraging council house sales. The article shows that slum clearance had long been central to the local council's provision of municipal housing and that apart from two short periods following the First and Second World Wars, council housing was conceived of primarily as a residual tenure by those in control of policy implementation. It further demonstrates that slum clearance between the 1920s and 1960s altered the social constituency for council housing and, combined with selective privatization, specific allocation policies and disinvestment, led to the stigmatization of certain inter-war estates. The article suggests that further case studies are needed in order to test the wider applicability of these arguments during the middle years of the twentieth century.     

Suburban Affairs: Groups and Political Communities Across Sydney

According to recent international research, political mobilisation at the local level no longer reflects socioeconomic divisions in society, but is instead based on a post-material oriented ‘politics of choice’. This proposition is applied to group politics within six Sydney communities. We broaden the examination of political activity undertaken by local groups to include lobbying, advocacy and community organising. This leads us to find that the primary variance among communities is in the type of activities undertaken rather than the level of group activity. In more privileged areas of Sydney, local groups are more likely to be constituted as traditional interest groups, including those that focus on post-materialist concerns. However, group activity remains substantial in less affluent areas, but manifests in different forms, including hybrid groups that combine service provision and advocacy.     

The 'Mardi Gras' Shipwreck: Results of a Deep-Water Excavation, Gulf of Mexico, USA

The 'Mardi Gras' Shipwreck is the remains of an early-19th-century sailing vessel lost in approximately 1220 m of water in the Gulf of Mexico. A recent archaeological investigation documented the wreck and recovered several artefacts, including glassware, ceramics, navigational instruments, a cannon, and a stove. Analyses of these artefacts and the surviving hull have led to preliminary conclusions on the nature of the vessel and its crew.
