    Notes: Abstract This paper considers the definitions of recursive and statelike representations form-D systems modeled as operators on a partially ordered Hilbert resolution space. Using only the causality structure we develop a second-order transition representation which encompasses previously studied models. The same representation is shown to be valid for both quarter plane and arbitrary conic causality structures. Transformation of the transition representation into a first-orderm-D local state model leads to the concept of structural minimality. We develop explicit conditions which apply to both stationary and nonstationary cases. The transition representation also enables us to establish the existence of general 1-D wave advance model representations. Minimality of the wave advance model is also discussed.

    Topics: Computer Science
    Notes: Abstract Developing knowledge bases using knowledge-acquisition tools is difficult because each stage of development requires performing a distinct knowledge-acquisition task. This paper describes these different tasks and surveys current tools that perform them. It also addresses two issues confronting tools for start-to-finish development of knowledge bases. The first issue is how to support multiple stages of development. This paper describes Protos, a knowledge-acquisition tool that adjusts the training it expects and assistance it provides as its knowledge grows. The second issue is how to integrate new information into a large knowledge base. This issue is addressed in the description of a second tool, KI, that evaluates new information to determine its consequences for existing knowledge.

    Topics: Computer Science
    Notes: Abstract This research examines the process of learning problem solving with minimal requirements for a priori knowledge and teacher involvement. Experience indicates that knowledge about the problem solving task can be used to improve problem solving performance. This research addresses the issues of what knowledge is useful, how it is applied during problem solving, and how it can be acquired. For each operator used in the problem solving domain, knowledge is incrementally learned concerning why it is useful, when it is applicable, and what transformation it performs. The method of experimental goal regression is introduced for improving the learning rate by approximating the results of analytic learning. The ideas are formalized in an algorithm for learning and problem solving and demonstrated with examples from the domains of simultaneous linear equations and symbolic integration.

    Notes: Abstract This longitudinal research study focused on persistence and financial aid of women, underrepresented minorities, and needy students majoring in science, engineering, and mathematics (SEM) in a large, public university in a metropolitan area. Beginning in fall 1989, four consecutive freshmen cohorts (n's = 1967, 1679, 1614, and 1924, respectively) were tracked through 1996–97. SEM majors persisted and graduated at higher rates, but took longer to graduate than non-SEM majors. Women, underrepresented minorities, and needy students received more gift aid than other student populations. However, only women had lower departure rates and graduated at higher rates than other SEM student populations. Compared to non-SEM majors, gift aid for SEM majors was more likely to be awarded on the basis of merit rather than need. Average loan indebtedness increased rapidly from 1989–90 through 1996–97 for both SEM and non-SEM majors. Implications of the findings for improved institutional and federal policy are indicated, and further research on the study topics recommended.
