To gain a better understanding of the effects on medical schools of transformations in medical practice, science, and public expectations, the AAMC in 1994 formed the Advisory Panel on the Mission and Organization of Medical Schools and appointed six working groups to address relevant issues. This article is a report of the findings of the Working Group on Preserving Medical Schools' Academic Mission in a Competitive Marketplace, which was charged with exploring how medical schools could acquire and/or preserve an adequate patient base for teaching, research, and income generation in a competitive marketplace. The other groups' reports will appear in future issues of Academic Medicine. To understand the diversity of approaches that schools have taken to achieve this goal and to preserve their missions, the group interviewed representatives of nine medical schools, selected to represent a cross section of U.S. medical schools. The interviews took place on four occasions between June 1995 and March 1996. The information and comments shared by participants helped the working group gain insight into the fundamental issues it had been charged to address, including those of new delivery structures, what value schools offer to delivery structures, how education and research can be incorporated and supported financially, possible new pressures on relationships between medical schools and teaching hospitals, changes in faculty physicians' employment relationships and terms, and the role of the medical school in graduate medical education. In collecting and analyzing the data, the working group focused on the distinction between protecting an institution's existing enterprise and preserving an institution's core mission. This article gives a detailed overview of the information and comments each school presented, organized under the appropriate question. The working group's conclusions and commentaries on the findings follow. An appendix presents more detailed summaries of the schools' presentations, organised as case studies. The picture that emerges is complex. The working group concluded that medical schools will take a variety of approaches to define and preserve their missions. Most, but not all, medical schools will be able to secure the patient bases necessary to fulfill their missions even in a competitive marketplace. However, the nature of many of the schools is likely to change, and it is not clear whether the core missions of education and research will continue at their present levels at all schools.

Current models of stellar chromospheres match either the global flux in the far ultraviolet emission lines or the details of a global line profile in order to obtain the atmospheric temperature structure. With this, it has been possible to model the global energy balance and derive a solution to the globally averaged physical properties of stellar chromospheres. However, such one component models do not actually characterize the physical structures which comprise the chromosphere, only the apparent mean structure.

This total program is directed toward development of a fixed boundary, shell-and-tube, gas-to-air recuperator, for a turboshaft gas turbine air craft engine, with 2000 hours design life. The object of Phase I of this recuperator development program is engineering designs, fabrication, and testing of full scale, 60 degree arc test sections and other required test specimens. Two different recuperator test sections were fabricated and tested. One was a U-tube unit with compressed air flowing through tubes and exhaust gas flowing over tubes (EOT). The other was a straight tube unit with exhaust gas flowing through tubes and compressed air flowing over tubes.
