The use of predictive modelling to target Neolithic settlement and occupation activity in mainland Scotland

A central aim of Neolithic studies in Europe is to understand settlement or domestic activity of the first agriculturalists. In Scotland, the continued absence of unambiguous Neolithic settlement or domestic occupation activities on the mainland remains an unresolved issue. It is proposed that areas attractive for settlement and occupation activities may be identified by constructing GIS-based models of sites believed to be related to settlement or occupation activities, including chambered cairns, timber halls, and sites containing pit-digging episodes. Statistical analyses undertaken in this process suggest new insights into the locations of the chambered cairns, timber halls, and pits. Finalised models are constructed and desktop assessments are conducted to examine model performance. Research priorities for improving significant environmental variables driving the current models are identified.     

Voluntary Approaches to Environmental Problems: Exploring the Rise of Nontraditional Public Policy

Government reliance on voluntary programs represents a significant shift in public policy: moving from command and control regulations to market based mechanisms. This article explores the determinants of Voluntary Remediation Programs (VRPs) in the American States. During the 1980s and 1990s, 44 states adopted VRPs to facilitate remediation of existing hazardous waste sites. Relying on diffusion of innovation theory, I develop a model of state policy adoption that explores the influence of internal state political and economic factors, as well as testing the influence of regional and top‐down diffusion forces. I utilize a discrete‐time event history approach to test this model. The results indicate that state policymaking is responsive to interest group pressure and the pace of cleanup at hazardous waste sites. Additionally, state policymaking is consistently influenced by the actions of surrounding state governments; the probability of adopting a voluntary program increases if surrounding states have already developed these policies.
