Download or read book Constructing strata of primary sampling units for the Residential Energy Consumption Survey written by Rachel M. Harter and published by RTI Press. This book was released on 2017-05-26 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2015 Residential Energy Consumption Survey design called for stratification of primary sampling units to improve estimation. Two methods of defining strata from multiple stratification variables were proposed, leading to this investigation. All stratification methods use stratification variables available for the entire frame. We reviewed textbook guidance on the general principles and desirable properties of stratification variables and the assumptions on which the two methods were based. Using principal components combined with cluster analysis on the stratification variables to define strata focuses on relationships among stratification variables. Decision trees, regressions, and correlation approaches focus more on relationships between the stratification variables and prior outcome data, which may be available for just a sample of units. Using both principal components/cluster analysis and decision trees, we stratified primary sampling units for the 2009 Residential Energy Consumption Survey and compared the resulting strata.

Download or read book Racial Discrimination and Minority Business Enterprise written by Jon S. Wainwright and published by Routledge. This book was released on 2014-01-14 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using a large microdata sample from the most recent decennial census, this book documents the economic disparities facing minority-owned business owners relative to non-minorities. The book incorporates a wide range of geographic and industrial categories and demonstrates that these disparities persist even when other important factors such as education, experience, wealth and family structure are held constant. Self-employed business owners comprise an important and growing sector of the U.S. economy. In contrast to wage workers, the issue of discrimination against minority business owners has received little attention from economists. However, recent U.S. Supreme Court decisions have made the continued constitutionality of affirmative action in public sector purchasing and contracting contingent upon documenting the existence of discrimination against such businesses within relevant geographic or industrial boundaries. The author shows that among prime working age males, being an entrepreneur is a relatively more lucrative form of employment, on average, than working for a wage. Typically, however, non-Hispanic whites become entrepreneurs at much higher rates and receive much higher earnings than their black, Hispanic, and Native American counterparts. The author's findings of racial and ethnic disparities are strongest for black and Native American entrepreneurs. Positive levels of discrimination facing Hispanic and Asian entrepreneurs are also documented. The book also includes discussion of relevant Supreme Court decisions, how economists attempt to measure discrimination and the major sources of data available for studying minority business enterprise.

Tierney and published by Transportation Research Board. This book was released on 2012 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Census microdata are the confidential records of specific individuals and housing units from whom Decennial Census or American Community Survey responses have been obtained. The U.S. Census Bureau also draws a sample from the full set of microdata and makes these sampled records available in the Public Use Microdata Sample (PUMS) data products, so that users can develop their own tabulations. These data are being used by state departments of transportation (DOTs) and metropolitan planning organizations (MPOs) for studies, such as analyses of the commuting characteristics of population subgroups, and for supporting travel demand model and land use models."--Preface

This book was released on with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the great challenges in ecophysiology is linking physiological measures in wild animal populations with changes in individual fitness. Physiological variables that indicate nutritional state, stress, disease, or injury are used extensively in veterinary practice and captive settings to assess the health and likelihood of reproductive success of many animals. The development and refinement of sampling methods that limit disturbance of animals, coupled with advancements in analytical methods have allowed researchers to begin to examine the relevance of these physiological parameters in wild animals for predicting population trends and response to environmental perturbations. However, despite extensive research in this field, consistent correlations between fitness and/or population health and physiological measures remain rare.

Download or read book Composition and Origin of Cometary Materials written by K. Altwegg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comet nuclei are the most primitive bodies in the solar system. They have been created far away from the early Sun and their material properties have been altered the least since their formation. Thus, the composition and structure of comet nuclei provide the best information about the chemical and thermodynamic conditions in the nebula from which our solar system formed. In this volume, cometary experts review a broad spectrum of ideas and conclusions based on in situ measurement of Comet Halley and remote sensing observations of the recent bright Comets Hale-Bopp and Hyakutake. The chemical character of comet nuclei suggests many close similarities with the composition of interstellar clouds. It also suggests material mixing from the inner solar nebula and challenges the importance of the accretion shock in the outer nebula. The book is intended to serve as a guide for researchers and graduate students working in the field of planetology and solar system exploration. Several special indexes focus the reader's attention to detailed results and discussions. It concludes with recommendations for laboratory investigations and for advanced modeling of comets, the solar nebula, and the collapse of interstellar clouds.

Download or read book Choosing Homes, Choosing Schools written by Annette Lareau and published by Russell Sage Foundation. This book was released on 2014-03-31 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of policy shifts over the past decade promises to change how Americans decide where to send their children to school. In theory, the boom in standardized test scores and charter schools will allow parents to evaluate their assigned neighborhood school, or move in search of a better option. But what kind of data do parents actually use while choosing schools? Are there differences among suburban and urban families? How do parents’ choices influence school and residential segregation in America? Choosing Homes, Choosing Schools presents a breakthrough analysis of the new era of school choice, and what it portends for American neighborhoods. The distinguished contributors to Choosing Homes, Choosing Schools investigate the complex relationship between education, neighborhood social networks, and larger patterns of inequality. Paul Jargowsky reviews recent trends in segregation by race and class. His analysis shows that segregation between blacks and whites has declined since 1970, but remains extremely high. Moreover, white families with children are less likely than childless whites to live in neighborhoods with more minority residents. In her chapter, Annette Lareau draws on interviews with parents in three suburban neighborhoods to analyze school-choice decisions. Surprisingly, she finds that middle- and upper-class parents do not rely on active research, such as school tours or test scores. Instead, most simply trust advice from friends and other people in their network. Their decision-making process was largely informal and passive. Eliot Weinginer complements this research when he draws from his data on urban parents. He finds that these families worry endlessly about the selection of a school, and that parents of all backgrounds actively consider alternatives, including charter schools. Middle- and upper-class parents relied more on federally mandated report cards, district websites, and online forums, while working-class parents use network contacts to gain information on school quality. Little previous research has explored what role school concerns play in the preferences of white and minority parents for particular neighborhoods. Featuring innovative work from more than a dozen scholars, Choosing Homes, Choosing Schools adroitly addresses this gap and provides a firmer understanding of how Americans choose where to live and send their children to school.

Book excerpt: Scientists and conservationists are beginning to understand the importance of top carnivores to the health and integrity of fully functioning ecosystems. As burgeoning human populations continue to impinge on natural landscapes, the need for understanding carnivore populations and how we affect them is becoming increasingly acute.Desert Puma represents one of the most detailed assessments ever produced of the biology and ecology of a top carnivore. The husband-and-wife team of Kenneth Logan and Linda Sweanor set forth extensive data gathered from their ten-year field study of pumas in the Chihuahua Desert of New Mexico, also drawing on other reliable scientific data gathered throughout the puma's geographic range. Chapters examine: the evolutionary and modern history of pumas, their taxonomy, and physical description a detailed description and history of the study area in the Chihuahua Desert field techniques that were used in the research puma population dynamics and life history strategies the implications of puma behavior and social organization the relationships of pumas and their preyThe authors provide important new information about both the biology of pumas and their evolutionary ecology -- not only what pumas do, but why they do it. Logan and Sweanor explain how an understanding of puma evolutionary ecology can, and must, inform long-term conservation strategies. They end the book with their ideas regarding strategies for puma management and conservation, along with a consideration of the future of pumas and humans. Desert Puma makes a significant and original contribution to the science not only of pumas in desert ecosystems but of the role of top predators in all environments. It is an essential contribution to the bookshelf of any wildlife biologist or conservationist involved in large-scale land management or wildlife management.
