A statistical analysis was performed to test the hypothesis that, if profit-maximizing firms have limited information about the general productivity of new workers, they may choose to use easily observable characteristics such as years of education to discriminate statistically among workers. Information about employer learning was obtained by…

The relationship between employer learning and statistical discrimination was explored through a statistical analysis that included a test for statistical discrimination or "rational" stereotyping in environments where agents learn over time. The test is used to study the working hypothesis that, because firms have only limited…

This paper provides a snapshot of developments in the electronic journal industry. The first section identifies issues affecting librarians and publishers, including: (1) issues of common concern to both publishers and librarians, e.g., lack of comparable data, lack of context, incomplete usage data, marketing, content provided, interface…

Information concerning educational conditions in the southern Appalachian region is scattered, fragmentary, and often partisan to the assumption either that conditions are ideal or that they are inconceivably bad. The purpose of this study is to draw together the available facts in the case. Necessarily, this study is largely statistical. The…

Describes how user interfaces for the Bureau of Labor Statistics (BLS) web site evolved over a 5-year period along with the larger organizational interface and how this co-evolution has influenced the institution. Interviews with BLS staff and transaction log analysis are the foci of this study, as well as user information-seeking studies and user…

Reports on a statistical study on student assessment of professors and courses. Discusses the loglinear probability model that was used to find that students' evaluations of an economics course and several behavior attributes of the course's instructor were interactive and significant. (DB)

This paper addresses conflicting views on whether there is now or will soon be a surplus of college graduates and other skilled workers by analyzing data from the Bureau of Labor Statistics (BLS). Ten questions (and the answers reached) are addressed: (1) "Do the latest BLS projections of college graduate supply actually predict a bust--a…

The use of quantitative graphics in newspapers requires achieving a balance between being accurate and getting the attention of the reader. The statistical representations in newspapers are drawn by graphic designers whose key technique is fusion--the striking combination of two visual images. This technique often results in visual puns,…

This research illustrates how statistical analysis of data was presented by the plaintiff's attorneys as evidence in litigation involving sexual and racial discrimination in the case Green v. City of Gadsden. Bar graphs depict the sexual and racial compositions of (1) members of the Gadsden Police Department (GPD), (2) members of the GPD in…

This document describes the review, analysis, and decision-making process that Trinity University, Texas, went through to develop the three-part computer network that they use to gather and analyze EEG (electroencephalography) and EKG (electrocardiogram) data. The data are gathered in the laboratory on a PDP-1124, an analog minicomputer. Once…

Meta-analysis, meta-evaluation and secondary analysis are methods of summarizing, examining, evaluating or re-analyzing data in research and evaluation efforts. Meta-analysis involves the summarization of research findings to come to some general conclusions regarding effects or outcomes of a given treatment/project/program. Glass's approach…

The proportions of a sample of Australian postsecondary students who continued with full-time study, the nature of that study, the institution at which it occurred, and the students' success were investigated in this research study. Those criterion variables were then related to the students' sex and father's occupation by means of two- and…

Substantial differences exist between the incomes of white and black Americans. These differences in income are a major aspect of inequality between blacks and whites. Improvements and declines in black income relative to white income have roughly paralleled expansions and contractions in the business cycle. Income differences are related to a…
