Coarse homology theories

In this paper we develop an axiomatic approach to coarse homology theories. We prove a uniqueness result concerning coarse homology theories on the category of `coarse CW-complexes'. This uniqueness result is used to prove a version of the coarse Baum-Connes conjecture for such spaces.Comment: Published by Algebraic and Geometric Topology at http://www.maths.warwick.ac.uk/agt/AGTVol1/agt-1-13.abs.htm

Analysis of selective chopper radiometer data

Data from SCR-B on Nimbus 5 have been processed to yield global, orbital temperatures at 10, 5, 2, 1, and 0.4 mb for the period January 1977 through April 1978 under the current task. In addition gridded values at 10 deg latitude by 20 deg longitude were prepared by space-time interpolation for the period January 1975 through April 1978. Temperature retrieval was based on regression of radiances against Meteorological Rocket Network data, with regressions recomputed at approximately six-month intervals. This data now completes a consistent time series from April 1970 to April 1978 for all available radiance data from SCR A and SCR B on Nimbus 4 and 5. The processing details for the current period are discussed, but is also applicable to the previous data periods. The accuracy of the temperature retrievals for each 6-month period for the entire eight years is given in the Appendices

Coarse topology, enlargeability, and essentialness

Using methods from coarse topology we show that fundamental classes of closed enlargeable manifolds map non-trivially both to the rational homology of their fundamental groups and to the K-theory of the corresponding reduced C*-algebras. Our proofs do not depend on the Baum--Connes conjecture and provide independent confirmation for specific predictions derived from this conjecture.Comment: 21 pages, 2 figures. Revised version.

Growth of Large-Scale Credit Unions in Iowa: Implications for Public Policy

Over the past two decades, the financial services industry has experienced a significant increase in competition and internal rivalry. Driven by deregulation and advances in information technologies, many historical institutional distinctions among financial intermediaries have disappeared or blurred considerably. The fundamental assumption that has guided many of the policy changes is that consumers are best served when businesses offering the same services are allowed to compete within a similar regulatory or institutional environment. Despite this general leveling of the playing field, credit unions continue to operate under tax and regulatory rules that differ, in important ways, from most of the firms in the financial services industry. Many of the tax and regulatory distinctions arose in the early 20th century during a time when credit unions were being established to meet the needs of individuals or communities that could not or were not being adequately served by commercial banks. However, as the financial services industry has evolved, the justification for continuing or maintaining credit unions

THE COST OF INACCURATE AUTOMOBILE MILEAGE INFORMATION

The model in this paper integrates the possibility of misinformation into consumer utility theory. If the utility realized from a good differs from the utility anticipated at time of purchase, shifts in demand would occur, and thus changes in consumer surplus. These changes provide a measure of the cost of misinformation or value of improved information. The empirical analysis yields estimates of the private and social cost of inaccuracies in automobile buyers; pre-purchase mileage estimates. If automobile purchases are based on imperfect gasoline mileage information, a discrepancy results between expected and actual fuel-efficiency. The data source is a survey of 1980 model car buyers conducted by the authors.Consumer/Household Economics,

THE COST OF INACCURATE CONSUMER INFORMATION: THE CASE OF THE EPA MILEAGE FIGURES

In this study a utility maximizing model is developed which accommodates changing states of information. Rational consumer choices in one state of information can lead to realizing different levels of utility than anticipated. Differences between these levels of utility suggest a measure for the value of information. This framework is applied to estimating the potential cost of possible inaccuracies in the EPA fuel-economy ratings. Survey data collected from new car buyers then are used to infer the magnitude of the actual costs that may be caused by the present EPA information.Consumer/Household Economics,
