Developing a tutoring module for presentation of computerized patient management problems

The simulation problem is one of the most commonly used formats in computer-assisted instruction (CAI). In medical education, a patient simulation problem is known as a patient management problem (PMP). A number of computerized PMP systems are currently available. However, to date, there is no record of PMP systems having been developed using artificial intelligence. This is noteworthy since artificial intelligence techniques could help in the generation of more effective and intelligent instructional systems.

This paper analyzes and evaluates existing instructional simulation software in clinical medicine in terms of effective educational design attributes. Components of effective PMP systems thus identified are incorporated into a computerized instructional system which uses artificial intelligence techniques for teaching problem-solving and diagnostic skills to undergraduate medical students.     

University research and development of a microsatellite

Developing a microsatellite at a university is an effective means of training engineering students for an R&D career. Such a programme requires the adoption of many research and development processes from industry. This paper describes how tailored forms of systems engineering, project management and technology management were applied to develop a high technology product at a tertiary educational institution. This microsatellite development programme has produced students who are well prepared for the realities of engineering practice, and a research and development facility that earns research funding for the university.     

TECHNICAL CHANGE IN PRODUCTION PROCESSES OF THE SEQUENTIAL INTERINDUSTRY MODEL

Transient processes important to understanding technical change are modeled using a time-varying version of the Sequential Interindustry Model, SIM. A simple process of technical change is explored, where a new production technique replaces an old one for one of an industry's production processes. Using several measures internal and external to the industry the model can help in understanding the complex processes of technical change, point to difficulties in their analysis, and suggest guidance to further examinations. An earlier version of this paper was presented at the Eighth International Conference on Input-Output Techniques, Sapporo, Japan, July 1986.     

Qualität im Journalismus – ein integratives Konzept

To determine the various performance criteria concerning journalism it is reasonable to develop a broad concept, which integrates the different theoretical approaches. In a functional and system-oriented perspective, fundamental performance criteria can be based on the social function and the specific code of journalism, which emerged in an historical process of mutual observation of journalists and audiences. In a normative-democratic perspective, performance criteria can be derived from societal and human values codified in diverse regulations. However, in this regard it has to be taken into account that specific claims of the political subsystem also play an important role. Finally from an audience and action oriented viewpoint, it is important to keep in mind that journalistic communication must be useful and applicable in the world the audience lives in.

The Marshallian macroeconomic model: A progress report

In this progress report, we first indicate the origins and early development of the Marshallian macroeconomic model (MMM) and briefly review some of our past empirical forecasting experiments with the model. Then we present recently developed one-sector, two-sector and n-sector models of an economy that can be employed to explain past experience, predict future outcomes and analyze policy problems. The results of simulation experiments with various versions of the model are provided to illustrate some of its dynamic properties that include “chaotic” features. Last, we present comments on planned future work with the model.     

Research article: Look after they leap: illustrating the value of retrospective reports in employee turnover

The prevailing methodology for studying employee turnover is limited because it emphasizes prediction rather than understanding. This paper critiques this methodology and draws out the implications of an alternative: retrospective self-reporting, by actual leavers. Retrospective self-reporting has three main advantages. First, it allows direct assessment of actual incidents of turnover, so interventions can be informed by accounts of real events, instead of being based on inference. Second, it offers insight into the dynamic character of decisions to quit, which are often unpredictable or precipitated by sudden events. Third, it allows for assessment of the role of non-work factors. This makes a methodological contribution, allowing greater insight into the decision to quit, which is ontologically, socially and dynamically complex. It has implications for how we construe and manage turnover. The argument is illustrated by a recent study of 352 UK National Health Service nurse leavers but has wider implications for turnover in the public sector.
