Florida, the University of Miami, and Florida International University. The IASCP faculty also includes members lo- cated at other universities and research laboratories both within the continental United States and abroad. The overall objective of IASCP is the maintenance of a scientific center of excellence focused on human commu- nicative behavior. The Institute's program includes (but is not confined to) three broad areas: 1) the communicator(s), i.e., the physiological/physical/psychological processes by which individuals generate and transmit communicative signals (speech), 2) the respondentss, and how receptive (hearing) and neural mechanisms function to process sig- nals within a variety of environments, and 3) the message, i.e., the codes and signs (language) that constitute the sum total of these communicative messages. The IASCP faculty includes students and scientists with a variety of interests and training. Expertise is represented by the phonetic sciences, speech pathology and audiology, psychology, psycholinguistics, linguistics, anthropology, psychoacoustics, auditory neurophysiology, electrical en- gineering, computer sciences, physics, communication studies, bilingual communication, biocommu-nication, den- tistry, and medicine. As stated, IASCP's overall research effort is basically an interdisciplinary one, but the focus of each investigator's interests is the advancement of knowledge about human communication.

INTERDISCIPLINARY RESEARCH CENTERS ACCOUNTING RESEARCH CENTER Established in 1976, the ARC is an integral part of the Fisher School of Accounting and of the College of Busi- ness Administration. It serves to develop and promote a scholarly environment for research in accounting with a special interest in interdisciplinary research. ARC holds frequent research seminars, organizes a biennial national research symposium on accounting and auditing stan- dards, and publishes the Journal ofAccounting Literature. For information, contact Director, Accounting Research Center, 267 Business Building. CENTER FOR AERONOMY AND OTHER ATMOSPHERIC SCIENCES The Center (ICAAS) is a community of scholars drawn from many disciplines represented at the University of Florida. Each scholar has an established professional knowledge and research capability in the atmospheric sciences or in physical, biological, or societal disciplines that relate closely to our atmospheric environment. As an interdisciplinary center, ICAAS promotes pure and ap- plied research in the atmospheric sciences and provides machinery for translating research into forms relevant to societal needs. Activities include a diverse range of bio- logical, ecological, and technological research related to INTERDISCIPLINARY RESEARCH CENTERS /45 the quality of the air. In particular, the development of clean combustion technologies which foster the energy needs of Florida and the nation while reducing harmful atmospheric emissions has been a major ICAAS focus of the past decade. These activities are dispersed widely in the Colleges of Engineering, Liberal Arts and Sciences, Agriculture, Medicine, Law, and Business Administra- tion. Interdisciplinary projects of ICAAS encompass (1) stud- ies of sources, atmospheric transformation, and transport of acidic substances for a Florida acid rain assessment; (2) studies of ultraviolet, visible, and infrared radiation levels reaching the ground for photobiological applications; (3) evaluation of the environmental impact for the conver- sion of Florida's oil boilers to coal including development of interpolated analytic wind roses and pollutant concen- tration contours for Florida; (4) interplay of energy pro- duction needs relative to air quality standards including the technical, scientific, medical, agricultural, psycho- logical, economic, and legal aspects of the energy/air quality problems resulting in a monograph "Coal Burning Issues" on an assessment of the impact of increased coal use in Florida; and (5) economic and environmental benefits of co-burning coal, coal-water slurries, biomass, and waste with natural gas for efficient energy recovery and reduced emissions. These energy-atmospheric envi- ronment projects have led to the formation of the Univer- sity of Florida-Tacachale-Clean Combustion Technology Laboratory (CCTL) which evolved from joint programs of ICAAS, the Department of Mechanical Engineering, IFAS Agronomy, and UF analytical departments. For further information, write the Director, Professor A.E.S. Green, ICAAS, Space Sciences Research Building. CENTER FOR APPLIED MATHEMATICS The Center consists of faculty from the Departments of Aerospace Engineering, Mechanics, and Engineering Sci- ence and of Mathematics. These faculty are interested in the application of mathematics to research problems in the physical, engineering, social, and biological sciences. Codirectors are Professors A. R. Bednarekand U. Kurzweg. CENTER FOR AQUATIC PLANTS The Center for Aquatic Plants is a multidisciplinary unit of the Institute of Food and Agricultural Sciences (IFAS). Established in 1978 by the Florida Legislature, the Center is the lead agency for coordinating research and educa- tional programs on aquatic plant ecology and manage- ment in Florida. The Center is also involved in national and international research and education programs. The Center encourages interdisciplinary research focused on biological, chemical, mechanical, and integrated aquatic plant managementtechniques and their impacton aquatic ecosystems. Scientists associated with the Center special- ize in aquatic plant ecology, plant pathology, entomol- ogy, phycology, physiology, fisheries, weed science, and limnology. Faculty and graduate students are associated with their respective departments in IFAS. Interested persons should contact the Director, Center for Aquatic Plants, 7922 NW 71st Street, Gainesville, Florida 32606.
