A jack knife is a pocket knife that is put to many tasks, because it's ready to hand. Often there could be a better tool for the job, such as a screwdriver, a scraper, or a can-opener, but these are not usually pocket items. In statistical terms, the expression implies making do with what's available. Another simile, of an extreme situation, is…

In the first of two experiments, we demonstrate the spread of a novel form of tool use across 20 "cultural generations" of child-to-child transmission. An experimentally seeded technique spread with 100% fidelity along twice as many "generations" as has been investigated in recent exploratory "diffusion" experiments of this type. This contrasted…

The present simulation study confirms that the corrected epsilon approximate test of B. Lecoutre yields a less biased estimation of population epsilon and reduces Type I error rates when compared to the epsilon approximate test of H. Huynh and L. S. Feldt. (SLD)

The primary purpose of this research is to examine the impact of estimation methods, actual latent trait distributions, and item pool characteristics on the performance of a simulated computerized adaptive testing (CAT) system. In this study, three estimation procedures are compared for accuracy of estimation: maximum likelihood estimation (MLE),…

Papers in this volume explore indicators of children's well-being in the following areas: cross-cutting issues; population, family, and neighborhood; and social development and problem behaviors. The first section includes: (1) "Potential and Problems in Developing Indicators on Child Well-Being from Administrative Data" (Robert M.…

Regional analysis is central to applied geographic research, contributing to better planning and policy development for a variety of societal problems facing the United States. The development of energy policy serves as an illustration of the capabilities of this type of analysis. The United States has had little success in formulating a national…

A framework is provided for asking research questions and implementing an applied urban research project. Chapter 1 gives a brief overview of the term "urban" and the field of urban research. Chapter 2 discusses how different levels of analysis can be used in doing urban research. Chapter 3 suggests the need for strategic thinking in the applied…

This report presents a preliminary analysis of Pennsylvania day care centers based on data obtained through questionnaires, site visitations, and observation. The sample of day care centrs is described in terms of two major variables: population density and funding. Topics include: (1) administration and organization; (2) staff (recruitment,…

The data in this report is drawn from the 1994 public library annual report and represents a snapshot of certain conditions that existed in Wisconsin public libraries at the end of 1993. Trustees and staff can use this data to identify an appropriate peer group and select a service target based on activities reported by that group. This companion…

Quantitative output measures for municipal and county public library services in Wisconsin provide points of reference for libraries to analyze their needs and establish primary service goals based on unique community-targeted services. Traditional input measures are also furnished, which produce various recommended targets, based on the size of…
