Radock Resigns; Accepts New Post
Michael Radock, senior vice president for development and university relations, will leave USC in June to accept a position as vice-president of the Aspen Institute.
He will be vice president for resource development for the Aspen Institute for Humanistic Studies, with headquarters in New York City and Aspen, Colorado.
Radock joined the USC staff July 1,1981, after 20 years as vice president of the University of Michigan.
“When I accepted President Zumberge’s invitation to join his executive staff last year, we both agreed that the duration of my appointment would be short,’'Radock said.
“I am happy for Mike and Helen that they have this exciting new challenge at the Aspen Institute,” Dr. Zumberge said.
"Mike has had a busy year at USC. His major thrust has been in gearing up for an expanded program of alumni giving.” Zumberge continued, “but this year also has seen the start of drives to complete the funding of the Cinema-TV building complex and the Norris Cancer Research Institute.”
Zumberge pointed out that overall private gifts to the university remained strong during the 1982 fiscal year.
“Gifts this year for all purposes are $51.5 million, compared to $41.5 million at the same time one year ago,” he said.
In accepting Radock’s resignation, Zumberge said he will immediately launch a national search for a successor.
Until Radock’s replacement is found, the programs under his supervision will be assigned temporarily to Dr. Cornelius Pings, senior vice president for academic affairs at USC.
Interim Dean John B. Orr
New Child Care Center to Open
Ground breaking for the Hoover Intergenerational Care Center was held near USC last Friday.
USC President James H. Zumberge, City Councilman Robert Farrell and representatives from the Community Redevelopment Agency were present.
The ceremony took place at 3217 University Ave, (between 32nd St. and Jefferson Blvd.).
Hoover Intergenerational Care, a nonprofit organization founded in 1977, has developed an intergenerational program to meet the need for child-care and senior-citizen involvement in the Greater Hoover Project area. The organization seeks to involve senior
citizens from the Foster Grandparent Program and teenagers from South Central Los Angeles to help with pre-school children enrolled in the program.
The new facility was made possible with support of several individuals and orgainza-tions, including Farrell, the Community Redevelopment Agency, the 32nd Street Elementary School, members of the Greater University Parish and area businessmen.
Also giving support to the new facility are USC’s Leonard Davis School of Gerontology and Thomas Kilgore, Jr., director of the university’s Office of Special Community Affairs. Funding for the center is provided by the State Department of Education.
Education Dean Named
John B. Orr has been appointed as the sixth dean of the School of Education. His appointment, effective immediately, followed an extensive national search.
“Dr. Orr has served ably this past year as interim dean of the school,” says Cornelius J. Pings, senior vice president of academic affairs, who announced the appointment.
“I am confident,” Pings says, “that his tenure as dean will bring academic and administrative strength to this important professional school.”
Orr, a nationally known social ethicist, joined USC in 1967 as an associate professor of religion.
He graduated from the University of New Mexico with a B.A. in political science and
received his graduate education at Yale University. He served as an associate professor and chairman of the department of philosophy at Texas A & M Univesity before coming to USC to teach social ethics.
At USC, he has served as director of the School of Religion and as Tansey Professor of Social Ethics. He was appointed interim dean of the School of Education last year.
Orr is the author of “Radical Suburb,” published by Westminster Press in 1970, and “Ethical Choice,” published by the Free Press in the same year. He has published widely in the fields of social criticism, sociology of values, and public policy in education. In recent years, he has given substantial attention to the development of
programs in “education of citizenship.”
He formerly was associated with the Southwest Regional Development Laboratory, a federal educational research and development facility in Austin, Texas. He was responsible for the area of intercultural education.
He edited a monograph, “Education and Social Change,” published by the U.S. Office of Education in 1967.
He was a consultant to the U.S. Senate on revision of the Higher Education Act of 1968 and later served as staff consultant to the Educational Task Force of the Greater Los Angeles Urban Coalition.
Orr lives with his wife and two children in Los Alamitos. He is a native of Long Beach.
Scientists Look to Ocean As Land Energy Dwindles
As traditional fuel supplies are being depleted on land, scientists are looking to the seas for new sources of energy.
"Offshore oil is only one way the ocean can be used as an energy source,” says Jacqueline Rohas, a marine education specialist at USC. “The ocean offers more possibilities than most people realize.”
“Energy can be produced form marine plant life, from wave and tidal power, from the salt content of seawater, or from the temperature differences in the ocean,” Rojas explains. “These are just a few of the technologies now being explored.”
As assistant director fbr marine education at USC’s Institute for Marine and Coastal Studies' Sea Grant Program, Rojas helps develop educational materials and activities to foster greater “marine awareness”in the elementary and secondary schools.
This summer she will teach a course, jointly offered by the Sea Grant Program and the School of Education’s department of curriculum and instruction, to help elementary and secondary teachers intergrate marine science concepts into their lesst ns.
Enery production is just one of the topics Rojas will include in her discussions on marine research, ecology and management.
As many as ten different technologies are currently being developed to tap the ocean’s energy resources, according to Sea Grant’s assistant director, Stuart Ross, a guest lecturer in the marine education course.
Technologies likely to have the greatest application are wave power and Ocean Thermal Energy Conversion [OTEC), says Ross, a specialist in ocean energy and policy, who directs Sea Grant’s Marine Advisory Services.
OTEC takes advantage of the temperature difference between water on the ocean floor and water near the surface.
“The same principle is used in a steam engine,” Ross explains. “A fluid (water) is boiled. It turns to gas (steam). It expands in the process, creating pressure. The pressure drives a turbine. The steam then condenses and goes back through the system to be boiled again.
“The system requires a high temperature to vaporize the fluid and low temperature to recon-dense it. Whenever you have a temperature differential, as you do in the ocean, you have the theoretical possibility of running an engine.”
Surface water can be used to heat and vaporize a fluid, and the colder water from the ocean floor can be used to condense the vapor. The maximum difference between surface / floor extremes is only about 40 degrees F., so an OTEC system uses a working fluid, like ammonia, that vaporizes at lower temperature and condeses at a higher temperature than water.
The optimal site for an OTEC power plant would be in a tropical climate, Ross adds. There, the surface/floor extremes would be the greatest, since the bottom temperature is essentially the same over the entire seabed.
One of the biggest hurdles is collecting the cold water.
“To get to the bottom, you would have to run a huge pipe, perhaps 50 feet in diameter, down
3,000	feet or more,” Ross says. “That’s an engineering problem of the first oreder. It has never been done in commercial practise.”
A different use of the ocean’s energy is a seagoing turbine that hameses wave power.
A unit being developed by Lockheed-Califomia Co. is a dome-shaped strucure, 250 feet in diameter, that floats just beneath the water’s surface. Waves enter a central core and form a whirlpool that acts as a giant flywheel. The swirling column of water turns a turbine wheel, which provides electrical power.
“The Japanese have perfected ships with hulls containing wave-activated machinery that generates energy,” Ross says. "And wave energy can also be used on a smaller scale — to power a single buoy with a radio transmitter and light, for example.”
Marine plants such as seaweed and kelp can be processed to produce methane or other fuels.
"Giant kelp -- the large, floating brown patches you see at the beach -- are the fastest growing plants in the world,” Rojas says. “They can grow up to two feet a day.”
Researchers are experimenting with bubble-enclosed “kelp farms,” Rojas says. The farms could be positioned in the open sea, and nutrients could be introduced to promote even faster growth.
Another potential energy source, salinity gradient power, trades on the osmotic pressure that occurs whenever salt water and fresh water meet.
“Giant membranes could be placed at the mouths of rivers to take advantage of the pressure difference,” Ross says.
