Book Description
Changes over time in the levels and patterns of crime have significant consequences that affect not only the criminal justice system but also other critical policy sectors. Yet compared with such areas as health status, housing, and employment, the nation lacks timely information and comprehensive research on crime trends. Descriptive information and explanatory research on crime trends across the nation that are not only accurate, but also timely, are pressing needs in the nation's crime-control efforts. In April 2007, the National Research Council held a two-day workshop to address key substantive and methodological issues underlying the study of crime trends and to lay the groundwork for a proposed multiyear NRC panel study of these issues. Six papers were commissioned from leading researchers and discussed at the workshop by experts in sociology, criminology, law, economics, and statistics. The authors revised their papers based on the discussants' comments, and the papers were then reviewed again externally. The six final workshop papers are the basis of this volume, which represents some of the most serious thinking and research on crime trends currently available.

Book Description
People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be described and future land change can be projected using land-change models (LCMs). LCMs are a key means for understanding how humans are reshaping the Earth's surface in the past and present, for forecasting future landscape conditions, and for developing policies to manage our use of resources and the environment at scales ranging from an individual parcel of land in a city to vast expanses of forests around the world. Advancing Land Change Modeling: Opportunities and Research Requirements describes various LCM approaches, suggests guidance for their appropriate application, and makes recommendations to improve the integration of observation strategies into the models. This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes. Advancing Land Change Modeling's recommendations for assessment of future data and research needs will enable model outputs to better assist the science, policy, and decisionsupport communities.

Book Description
This book assesses the effects of spatially concentrated programs for housing and neighborhood improvement. These programs provide direct assistance to low-income property owners in an attempt to arrest neighborhood decline and encourage revitalization. The authors used the Harvard Urban Development Simulation Model (HUDS) in evaluating these programs. HUDS, a large-scale computer model, represents the process of housing rehabilitation, the production and consumption of housing services, household moving decisions, and other determinant of neighborhood change. The model simulates the behavior of approximately 80,000 individual households in two hundred residential neighborhoods of various quality levels. Unlike more aggregate models of urban development, HUDS has the capacity to identify how specific housing policies affect individual households as well as particular neighborhoods. Since program evaluations are no better than the models on which they are based, the authors provide sufficient detail to permit those readers primarily interested in the policy analysis to assess the methodology and to understandhow the policies are represented in the model; a more technical discussion of the model is then presented in appendixes. Although the simulations focus on policies that induce central-city property owners to upgrade their properties and thus stimulate revitalization, many of the authors' findings are relevant to larger issues of urban development. For example, the analysis of how housing rehabilitation subsidies affect the investment behavior of nonsubsidized property owners provides insights about the link between initial upgrading and sustained neighborhood improvement. The analysis also demonstrates how differences in location, household, and housing stock characteristics affect a particular neighborhood's responsiveness to a common policy initiative.

Book Description
The Economics of Neighborhood integrates neighborhood into contemporary notions of the urban economy. Neighborhood is viewed as a good with demand, supply, and equilibrium aspects. Topics covered range from demand for neighborhood and interneighborhood mobility to neighborhood choice and transportation services. The role of governments as suppliers of neighborhoods is also considered. Comprised of 12 chapters, this book begins with an introduction to some of the efforts to measure neighborhood effects and the approaches used in analyzing the role of neighborhood in the urban economy. The next section deals with the determinants of neighborhood demand in different eastern and midwestern cities in the United States in the mid- to late 1960s. The location choice of a sample of Pittsburgh households is examined, along with the role that neighborhood transition at the origin played in governing the decision to move or stay put. Subsequent chapters focus on the neighborhood choice of households already living in Washington, D.C., in 1968 as a joint prior choice of residential location, housing type, automobile ownership, and mode of travel to work; how the supply of certain kinds of neighborhoods can be determined by the interaction of residential demand and housing supply in the private sector; and optimum neighborhood supply by local governments. The concluding section analyzes neighborhood in an equilibrium setting, with emphasis on price outcomes and the quantity aspects of neighborhood. This monograph will be of value to economists as well as to researchers and students interested in urban economics.

Book Description
The Changing American Neighborhood argues that the physical and social spaces created by neighborhoods matter more than ever for the health and well-being of twenty-first-century Americans and their communities. Taking a long historical view, this book explores the many dimensions of today's neighborhoods, the forms they take, the forces and factors influencing them, and the people and organizations trying to change them. Challenging conventional interpretations of neighborhoods and neighborhood change, Alan Mallach and Todd Swanstrom adopt a broad, inter-disciplinary perspective that shows how neighborhoods are messy, complex systems, in which change is driven by constant feedback loops that link social, economic and physical conditions, each within distinct spatial and political contexts. The Changing American Neighborhood seeks to understand neighborhoods and neighborhood change not only for their own importance, but for the insights they offer to help guide peoples' efforts sustaining good neighborhoods and rebuilding struggling ones.

Book Description
An examination of the neighborhood transformation, gentrification, and displacement that accompany more compact development around transit. Cities and regions throughout the world are encouraging smarter growth patterns and expanding their transit systems to accommodate this growth, reduce greenhouse gas emissions, and satisfy new demands for mobility and accessibility. Yet despite a burgeoning literature and various policy interventions in recent decades, we still understand little about what happens to neighborhoods and residents with the development of transit systems and the trend toward more compact cities. Research has failed to determine why some neighborhoods change both physically and socially while others do not, and how race and class shape change in the twenty-first-century context of growing inequality. Drawing on novel methodological approaches, this book sheds new light on the question of who benefits and who loses from more compact development around new transit stations. Building on data at multiple levels, it connects quantitative analysis on regional patterns with qualitative research through interviews, field observations, and photographic documentation in twelve different California neighborhoods. From the local to the regional to the global, Chapple and Loukaitou-Sideris examine the phenomena of neighborhood transformation, gentrification, and displacement not only through an empirical lens but also from theoretical and historical perspectives. Growing out of an in-depth research process that involved close collaboration with dozens of community groups, the book aims to respond to the needs of both advocates and policymakers for ideas that work in the trenches.

Book Description
This book provides a detailed overview of the concepts, techniques, applications, and methodological approaches involved in land use and cover change (LUCC) modeling, also known simply as land change modeling. More than 40 international experts in this field have participated in this book, which illustrates recent advances in LUCC modeling with examples from North and South America, the Middle East, and Europe. Given the broad range of geomatic approaches available, it helps readers select the approach that best meets their needs. The book is structured into five parts preceded by a foreword written by Roger White and a general introduction. Part I consists of four chapters, each of which focuses on a specific stage in the modeling process: calibration, simulation, validation, and scenarios. It presents and explains the fundamental ideas and concepts underlying LUCC modeling. This is complemented by a comparative analysis of the selected software packages, practically applied in various case studies in Part II and Part III. Part II discusses recently proposed methodological developments that have enhanced modeling procedures and results while Part III offers case studies as well as interesting, innovative methodological proposals. Part IV revises different fundamental techniques used in LUCC modeling and finally Part V describes the best-known software packages used in the applications presented in Parts II and III.

Book Description
Over the last 25 years a vast body of literature has been published on neighbourhood effects: the idea that living in more deprived neighbourhoods has a negative effect on residents’ life chances over and above the effect of their individual characteristics. The volume of work not only reflects academic and policy interest in this topic, but also the fact that we are still no closer to answering the question of how important neighbourhood effects actually are. There is little doubt that these effects exist, but we do not know enough about the causal mechanisms which produce them, their relative importance in shaping individual’s life chances, the circumstances or conditions under which they are most important, or the most effective policy responses. Collectively, the chapters in this book offer new perspectives on these questions, and refocus the academic debate on neighbourhood effects. The book enriches the neighbourhood effects literature with insights from a wide range of disciplines and countries.
