We use a unique data set of annuities in the United Kingdom to test for adverse selection. We find systematic relationships between ex post mortality and annuity characteristics, such as the timing of payments and the possibility of payments to the annuitant's estate. These patterns are consistent with the presence of asymmetric information.…

Sixteen tables are presented for critical values of the larger of two sample correlation coefficients from two independent samples, given the sample size and the value of the smaller correlation. These tables allow quick assessment of significance without requiring calculation of the test statistic. (SLD)

This paper explores the issues involved in the linguistic characterisation of disordered discourse and the ways in which a Systemic Functional Linguistic framework addresses these issues. For many years, language disorders were described in terms of formal grammars, with "breakdown" discussed in terms of one or more of the traditional levels of…

Discusses O'Neill's proposal for the colonization of space as it offers new problems in pure physics. Addresses specifically the distribution of the atmosphere in O'Neill's habitat and whether there will be enough air at the axis of rotation to allow human-powered flight, with particular reference to the habitat's "artificial gravity."…

Discusses how the discovery of chaos has created a new paradigm in scientific modeling and how findings are contributing to changes in thought about many different branches of science. Includes explanations and examples of how chaotic behavior can be understood. (ML)

Presents a mechanical model for an ecology laboratory that introduces the concept of optimal foraging theory. Describes the physical model which includes a board studded with protruding machine bolts that simulate prey, and blindfolded students who simulate either generalist or specialist predator types. Discusses the theoretical model and data…

Considers several cosmological facts that relate to formulating accurate models about the universe, including the red shift, the unbounded universe, and the curvature of space. (CS)

Presents a model of the cardiovascular system which solves a set of interacting, possibly nonlinear, differential equations. Figures present a schematic diagram of the model and printouts that simulate normal conditions, exercise, hemorrhage, reduced contractility. The nine interacting equations used to describe the system are described in the…

Precise transcript development is vital to the articulation and transfer of credit. The transcript, the institution's award of credit, must present the institution's relation to experiential learning; transcription practices must allow institutions to communicate with third parties. Sample transcripts are provided. (MLW)

This article synthesizes articles discussed as part of the research symposium at the 24th International Conference on Learning Disabilities on October 11, 2002. Topics include translating learning disability research to practice, identification of learning disabilities, special education and postmodernism, and the response to treatment model.…

Focuses on the brain processes and brain systems involved in learning and memory from a neuropsychological perspective of analysis. Reports findings related to the locus of memory storage, types of memory and knowledge, and memory consolidation. Models of animal memory are also examined. An extensive reference list is included.
