Retreating glacier fronts on the Antarctic Peninsula over the past half-century.

The continued retreat of ice shelves on the Antarctic Peninsula has been widely attributed to recent atmospheric warming, but there is little published work describing changes in glacier margin positions. We present trends in 244 marine glacier fronts on the peninsula and associated islands over the past 61 years. Of these glaciers, 87% have retreated and a clear boundary between mean advance and retreat has migrated progressively southward. The pattern is broadly compatible with retreat driven by atmospheric warming, but the rapidity of the migration suggests that this may not be the sole driver of glacier retreat in this region.

Utilization and management of multiskilled health practitioners in U.S. hospitals.

This article examines the utilization and management of multiskilled health practitioners by U.S. hospitals. Results indicate such utilization is greatest for small hospitals as well as for other not-for-profit and government nonfederal hospitals. Flexibility, efficiency, and cost containment are the major reasons for utilizing such personnel. Secondary skills added to most multiskilled workers were of a parallel or lower level. Managerial issues and implications in utilizing multiskilled workers including training, compensation, evaluation, supervision, and competency assessment are also discussed.

The multiskilled health practitioner movement: where are we and how did we get here?

Multiskilled practitioners have been in health care settings for a long time. The form multiskilled practitioners have taken has varied with the cultural, socioeconomic, and technological constructs of the times. Some multiskilled practitioners have come and gone while others, such as the medical assistant and physician assistant, have remained. The complexity and sophistication of skills being combined have increased over time as have the degree level and opportunities for dual certification. Skills have been combined both across and within disciplines. There is currently a greater number and variety of formal programs to prepare multiskilled health practitioners in educational institutions and health care facilities, and more informal on-the-job training efforts than ever before--and they are increasing. Employment of multiskilled personnel has become a survival strategy for health care institutions in this current era of cost containment. Multiskilled allied health practitioners with basic nursing skills (ie, LPN level) may also provide one step toward a solution to the nursing personnel shortage being experienced by some health care facilities. The catchword for multiskilled has become not "whether," but "how."15 It is to everyone's benefit to learn from the efforts of those with experience in implementing the multiskilled health practitioner concept for both national and international application. The National Multiskilled Health Practitioner Clearinghouse intends, through its publications, services, and resource files, to serve as the cornerstone upon which the information from those with experience can be reposited and disseminated.

Marketing physician services in an academic medical center.

As a result of recent environmental changes in the health care industry, marketing has become a vital necessity for the survival of most hospitals. Kotler's conceptual framework is used to study and evaluate an innovative program for marketing physician services in a large urban medical center. This program was quite successful in increasing admissions and referrals and won a national award in 1984.

Refractive change in hyperglycaemia: hyperopia, not myopia.

Sudden changes in refraction are well recognised feature of hyperglycaemia. A tendency towards myopia has always been associated with elevations in blood glucose. Twelve diabetic patients were found to have experienced such refractive changes. Review of their records demonstrates that hyperglycaemia produces hyperopia. A theoretical mechanism for this phenomenon is discussed.
