The Earth appears to be at the beginning of sixth massive species extinction. This paper balances a review of the forces threatening species survival with a comprehensive scan of factors that could act as counterweights. These factors could lead to four types of evolution—cultural, regulatory,...

This article explores the problem of evaluating programs with numerous jurisdictional implementations. Typically, budget and time constraints may not allow evaluation of every instance of program implementation. Therefore, a method is needed to guide the selection of a sample of implementations,...

During this period of reductions in government social programs, there is great value in developing program evaluation methods that are low cost and timely. This article explores the use of past evaluation data to develop statistical models useful in predicting future program performance. Model...

We analyze household decisions to use wood for space heating. Logistic regression and simultaneous equation models are estimated by using billing history and survey data collected from households in the Pacific Northwest. Strong positive determinants of wood use are size of the household,...

Discrete choice models are developed for decisions to participate in home energy audit and loan programs. A nested logit model of joint audit and loan decisions is also estimated. The results suggest that attitudinal variables concerning the information value and convenience of audits are the...

This study evaluates how urban residents value variety, spatial configuration, and patterns of open space in their neighborhoods. Quantitative matrices that were borrowed from landscape ecology were first used to measure the variety and spatial arrangement of open space plots and landuses around...
