The principles of modern genetics are extended to study the extinction probabilities of such genetic diseases as sickle-cell anemia, Tay-Sachs disease, and cystic fibrosis. (JT)

Presents a coordination level matching algorithm to be used in document retrieval systems that incorporate relevance feedback strategies. It is argued that this algorithm may eliminate the need for the frequent reevaluation of documents that is currently found in such systems, and conditions under which reranking is unnecessary are given.…

Examines library availability studies for the past 50 years as a measure of library effectiveness and looks at their differing sources of study samples, methods for gathering data, categories of nonavailability, and data analysis. The Kantor branching technique developed in 1976 is described as the standard analysis method. (Author/EM)

The effects of a teaching program in probability devised for students in grades five to seven were analyzed. Most of the notions were too difficult for fifth graders; 60-70 percent of the sixth graders and 80-90 percent of the seventh graders were able to understand and use correctly most of the concepts.

Discusses methods for integrating mathematics with study of culture and history to encourage awareness of its role in everyday life: comparing number words in foreign languages; discussing number origins, numerical symbols of ancient societies, games of skill and chance; and examining different housing styles to develop geometry and measurement…

After a review of the disadvantages of linear models for estimating the probability of academic success from previous school records and admission test results, the use of a probit model is proposed. The model is illustrated with admissions data from the Ecole des Hautes Etudes Commerciales in Montreal. (Author/BW)

The need for hands-on computer laboratory experience in undergraduate and graduate statistics education has been firmly established in the past decade. As a result a number of attempts have been undertaken to develop novel approaches for problem-driven statistical thinking, data analysis and result interpretation. In this paper we describe an…

Using multi-spell discrete time binary logistic regression, this study examined sequential occurrences of students' departures and returns over the period of six years. The model included time-invariant (gender, ethnicity, parents' educational attainment, family income, timing of matriculation, high school performance, and geographic origin) and…

Included in this section are brief articles outlining an approach to teaching mental computation, an inductive approach to algebra, and using football to teach probability. (MNS)

Discusses a short computer program used in teaching the random (RND) function in the BASIC programming language. Focuses on the mathematical concepts involved in the program related to elementary probability. (JN)
