The Economic Consequences of Slowing Population Growth is a collection of papers dealing with the economic implications of a sustained low fertility rate on an industrialized country. The book reviews the situation prevailing in the United States including the country's demographic trends and prospects. The text also presents the uncertainties, the unknown, and the known economic consequences of low fertility as analyzed from previous generations. One paper examines the lessons that can be learned from a zero population growth in Europe by comparing theory and reality. This paper expounds on the social and economic effects while transitioning to a zero growth rate. Other papers examine the inter-relationships between unemployment, inflation, and economic policy. These papers also give recommendations to cut unemployment levels without causing inflation in the process. Other papers discuss social security and other needs of an aging population. One paper examines rising concerns over population movements in times of slower U.S. population growth; the author cites data reflecting migration trends and population declines in several metropolitan areas. The text can prove useful for sociologists, social workers, public health services officers, and public economists.

Since the beginning of space flight, the collision hazard in Earth orbit has increased as the number of artificial objects orbiting the Earth has grown. Spacecraft performing communications, navigation, scientific, and other missions now share Earth orbit with spent rocket bodies, nonfunctional spacecraft, fragments from spacecraft breakups, and other debris created as a byproduct of space operations. Orbital Debris examines the methods we can use to characterize orbital debris, estimates the magnitude of the debris population, and assesses the hazard that this population poses to spacecraft. Potential methods to protect spacecraft are explored. The report also takes a close look at the projected future growth in the debris population and evaluates approaches to reducing that growth. Orbital Debris offers clear recommendations for targeted research on the debris population, for methods to improve the protection of spacecraft, on methods to reduce the creation of debris in the future, and much more.

Written by the 2018 Mindel C. Sheps Award winner, this textbook offers a unique method for teaching how to model spatial (multiregional) population dynamics through models of increasing complexity. Each chapter in this programmed workbook starts with a descriptive text, followed by a sequence of exercises focused on particular multiregional models, of increasing complexity, and then ends with the solutions. It extends the current developments in the spatial analysis of social data towards improving our understanding of dynamics and interacting change across multiple populations in space. Frameworks for analyzing such dynamics were first proposed in multiregional demography, over 40 years ago. This book revisits these methods and then illustrates how they may be used to analyze spatial data and study spatial population dynamics. Topics covered include spatial population dynamics, population projections and estimations, spatial and age structure of migration flows and much more. As such this innovative textbook is a great teaching and learning tool for teachers, students as well as individuals who want to study demographic processes across space.

Many ecological phenomena may be modelled using apparently random processes involving space (and possibly time). Such phenomena are classified as spatial in their nature and include all aspects of pollution. This book addresses the problem of modelling spatial effects in ecology and population dynamics using reaction-diffusion models. * Rapidly expanding area of research for biologists and applied mathematicians * Provides a unified and coherent account of methods developed to study spatial ecology via reaction-diffusion models * Provides the reader with the tools needed to construct and interpret models * Offers specific applications of both the models and the methods * Authors have played a dominant role in the field for years Essential reading for graduate students and researchers working with spatial modelling from mathematics, statistics, ecology, geography and biology.

The Journal of Irreproducible Results is the funniest thing to happen to science since Archimedes ran naked through the streets of Syracuse." --Discover Science humor magazine The Journal of Irreproducible Results has targeted "hypocrisy, arrogance, and ostentatious sesquipedalian circumlocution" since 1955. JIR editor Norman Sperling presents humorous and quirky tidbits relating to science, math, academia, bureaucracy, and witty word play. More than 250 entries ponder and pun the practical and peculiar. Consider OSHA's definition of the word "exit" as compared to Merriam Webster's: OSHA states, "Exit is the portion of a means of egress which is separated from all other spaces of the building or structure by construction or equipment as required in this subpart to provide a protected way to travel to exit discharge." Webster's defines "exit" as, "A way out of an enclosed place or space." If you've ever questioned the warning label on your hand drill that reads, "This product is not intended for use as a dental drill," or wonder what the "punishable by law" penalty is for snipping off that warning label on your pillow or mattress, then this book is for you.
