Ecology of Hierarchical Landscapes
The idea for this book grew out of: (1) the realisation that development of the theory of landscape ecology has now reached the point where rigorous field work is required to validate models, test assumptions and ideas of scaling theory, and refine our understanding of landscape features and their delineation; (2) the relative scarcity of compilations that have examined the role of field research or interdisciplinary management applications in advancing the science of landscape ecology; and (3) the increasing amount of information coming out of the Chequamegon Integrated Field Project (CIFP) on relevant topics. This book synthesises the experiences and lessons learned from the CIFP project and other relevant landscape studies in an attempt to demonstrate the utility of field studies and emerging technology to the advancement of the science. This book is organised to synthesise and update knowledge on research topics mentioned previously, with an emphasis on ecological consequences (i.e., implications for ecological function) of the approach to and understanding of these topics across levels of the ecological hierarchy.

Alcohol and Homicide
The relationship between alcohol and homicide in America is explored both historically and theoretically, providing the groundwork for two empirical analyses. The first, a theoretical approach, leads to the development of a selective disinhibition hypothesis, the implications of which are tested in a longitudinal analysis of alcohol availability and homicide in 256 U.S. cities between 1960 and 1980. Alcohol availability was found to significantly increase homicide rates. Availability also interacted with city poverty rates, lack of social bonds, and the age structure to further increase the incidence of murder. The second analysis, policy based, focuses on the impact on youth homicide rates of increases in the minimum age of purchase for alcohol, enacted by most states during the 1980s. This analysis shows that increases in the minimum drinking age had a significant impact on certain types of youth homicide. The book concludes with a discussion of the causes of the alcohol and homicide relationship, public policy and crime control alternatives for reducing alcohol related homicide, and other ongoing research that addresses these and other issues.
