The use of individual patient data (IPD) in network meta-analysis (NMA) is becoming increasingly popular. However, as most studies do not report IPD, most NMAs are performed using aggregate data for at least some, if not all, of the studies. We investigate the benefits of including varying proportions of IPD studies in an NMA. Several models have…

A relatively simple Gaussian-type diffusion simulation model for calculating urban carbon (CO) concentrations as a function of local meteorology and the distribution of traffic is described. The model can be used in two ways: in the synoptic mode and in the climatological mode. (Author/BL)

This paper describes and illustrates the use of a recently developed management simulation-information model, suggesting it as one possible step toward partial solution of two longstanding concerns in educational administration. These problems are (1) the myopic and parochial "problems" view of education and (2) the schism between professor and…

The authors investigated the feasibility of desiging cost/benefit, or cost effectiveness models for two alternative organizations within United States Air Force: the United States Air Force Academy and the Reserve Officer Training Corps of Air University. On the basis of the situation analyses, two cost simulation models for both institutions were…

A theory is proposed of the processes which enable a subject to learn while solving a problem. One subject's protocol--including 224 steps and taking 90 minutes--is described. Adequacy of the mechanisms is guaranteed by a computer simulation of the processes in an adaptive production system. (Author/GDC)

An effort to construct a model of the thermal properties of materials based on theoretical thermo-electromagnetic models, to construct a data base of the dense cultural hospital scene according to Defense Mapping Agency Aerospace Center (DMAAC) specifications, and to design and implement a program to evaluate the tonal model and generate imagery…

The Needs Assessment Project will construct a computerized simulation model to evaluate the educational needs of all the community in order to keep educational changes compatible with community needs. This paper presents the approach to be taken in developing the Needs Assessment Model: a description of the study with a review of related…

The minicomputer-based Computerized Diagnostic and Decision Training (CDDT) system described combines the principles of artificial intelligence, decision theory, and adaptive computer assisted instruction for training in electronic troubleshooting. The system incorporates an adaptive computer program which learns the student's diagnostic and…

Eight appendixes to a final report "Alternative Federal Day Care Strategies for the 1970's" comprise this volume. The appendixes are as follows: A. References for Estimation and Evaluation of Impacts upon Children and Parents--contains a list of 292 studies, articles, and reports published between 1958 and 1971; B. Impacts of Preschool…

A synthetic performance test is a job performance test that has been degraded to some degree in the range of tasks covered or in the fidelity of stimulus/response features. Since further development is needed before synthetic performance testing is valid and efficient, this research project focused on three objectives: to (1) identify problems…
