Decomposition of organic matter controls the flow of carbon and nutrients in terrestrial and aquatic ecosystems. Several kinetic laws have been proposed to describe decomposition rates, but they neglect adaptation of the microbial decomposer to environmental conditions. Here we formalise decomposition as an optimal control problem by assuming that…

This study aims to evaluate ChatGPT's capabilities in certain numerical analysis problem: solving ordinary differential equations. The methodology which is developed in order to conduct this research takes into account the following mathematical abilities (defined according to National Centre for Education Statistics): Conceptual Understanding,…

Many interesting research and design questions occur at the intersections of traditional disciplines, yet most coursework and research programs for undergraduate engineering students are focused on one discipline. This leads to underutilization of the potential in better preparing students through multidisciplinary projects. Identifying this…

When computer scientists discuss the computational complexity of, for example, finding the shortest path from building A to building B in some town or city, their starting point typically is a formal description of the problem at hand, e.g., a graph with weights on every edge where buildings correspond to vertices, routes between buildings to…

Presents a model relating the adequacy of an organization's problem-solving to its resources and to the appropriateness of its structures. Describes a test of the model, on 25 public elementary and secondary schools in southeastern Michigan, which found that different organizational structures use money differently and produce different outputs.…

Most educational management systems currently define organizational roles in terms of the operations to be performed. A more efficient manner of organization might be one that operates in terms of objectives to be reached. One way of implementing such a problem solving structure, would be to assign a particular problem to administrative personnel…

The Massachusetts General Hospital/Surgical and Special Services study, an information processing system for redesigning an outmoded existing hospital, structured information into small-scale elements that could be analyzed, reassembled into different solutions, and the solution selected that best accommodates all of the complex requirements.

Examines three different regression models of small group problem solving. (JK)

Home management students aid couple with cerebral palsy in solving home management problems with a systems approach. (AG)

This paper presents the concepts of a computer-directed system to improve human performance in structured learning situations. Attention is focused on finite-state systems in order to provide a systematic method for constructing training systems and to assist in analysis of problem solving and curriculum planning. The finite-state approach allows…

This 4-part document provides an overview of educational evaluation. Part I outlines the problems in educational evaluation, distinguishing between evaluations of student performance (objective attainment) and those of system operation (cost-effectiveness). Part II reviews existing practices in educational evaluation, focusing on the evaluation of…

Research of 25 Michigan elementary and secondary public schools is used to test a model relating organizations' problem-solving adequacy to their available inputs or resources and to the appropriateness of their structures. Problems that all organizations must solve, to avoid disorganization or entropy, include (1) getting inputs and producing…

The main purpose of the research reported in this document was to discover whether controlled experiments can be conducted on the relations between people and the complex computing systems which they use. Three increasingly complex experiments were designed to test the effect of varying delays of computer response on the number of commands issues…

This university level course in economic geography emphasizes the need for control of the spatial allocation of our resources, and strives for heightened student awareness of the world as a complex. It may thus be considered an introduction to geocybernetics, the study of man/machine relationships in the control of spatial organization. A systems…
