With binge alcohol consumption extracting a deadly toll on college campuses and cigarette smoking the chief preventable cause of cancer in the United States, the College of Communications and the Pennsylvania Center for the First Amendment will hold a roundtable discussion to address the legal, ethical, health and marketing issues surrounding the advertising of alcohol and tobacco products.
Slated for 7:30 p.m. Wednesday, March 26, at the Kern Graduate Center in Assembly Room 112, the discussion brings together experts from The Smeal College of Business Administration, University Health Services and the College of Communications.
"You've got child-friendly cartoon figures like Joe Camel pushing cigarettes and a flotilla of frogs croaking for Budweiser. Despite the potentially deadly appeal of these figures, the First Amendment protects such commercial speech," said Clay Calvert, assistant professor of communications and associate director of the Pennsylvania Center for the First Amendment at the University.
Panelists include: Marvin Goldberg, a professor in The Smeal College of Business Administration who specializes in social marketing; Natalie Croll, assistant director of University Health Services; Chuck McMellon, professor in the College of Communications who teaches advertising; and Calvert, who specializes in media law and policy issues.
Jeremy Cohen, associate dean of undergraduate studies in the College of Communications, will moderate the discussion and invite participation from the audience.
The Pennsylvania Center for the First Amendment, founded in 1992, conducts educational conferences for lawyers, judges, journalists, educators and the general public. In addition, the center is a resource for the media and the public, and has provided expert testimony to courts and legislatures.
Tony Kushner, award-winning author of "Angels in America" and prominent gay activist, will speak in Eisenhower Auditorium at 8 p.m. Monday, March 24.
Known for his Pulitzer Prize- and Tony Award-winning play, "Angels in America," Kushner's famous work consists of two plays: "Millennium Approaches" and "Perestroika." A seven-hour long play dealing with AIDS and the crisis of conscience the epidemic poses to America, "Angels" has won almost every major theatrical award since opening in Los Angeles in 1992. An upcoming major motion picture based on the play will be directed by Robert Altman.
Integrating historical figures such as Ray Cohn with a potpourri of characters both gay and straight, "Angels" has played to rave reviews in New York City's Walter Kerr Theatre since 1993. In 1994, the play began its national tour.
Kushner has received numerous playwriting fellowships and awards and taught at New York University, Yale, the University of Iowa, Princeton and the Julliard School of Drama. He has a bachelor's degree from Columbia University and a master of fine arts degree from New York University.
Fifth in the Distinguished Speakers Series, Kushner's presentation is co-sponsored by the Lesbian Gay Bisexual Student Association. Tickets are free and will be available in 225 HUB. For more information, contact Carol German in the Office of Student Activities at (814) 863-3786.

"AIDS; Search for a Cure," a March 27 luncheon lecture, will be given by Kenneth A. Johnson, Paul Berg professor of biochemistry, at noon in 110 N. Henderson, The Living Center, on the University Park campus.
By the year 2000, 40 million people will be infected with HIV, the virus that causes AIDS. There has been considerable excitement over new drugs that may afford a cure in some individuals. However, this excitement is tempered by concerns over the ability of the virus to mutate rapidly, leading to resistant forms of the virus. Johnson will discuss his research on dealing with these issues in developing better drugs used to treat AIDS.
This free lecture is sponsored by the Penn State Chapter of Sigma Xi.
Michael Hout, professor of sociology and director of the Survey Research Center at the University of California -- Berkeley, will deliver the 1996 Francis Sim Memorial Lecture at 8 tonight in 101 Thomas Building on the University Park campus. Hout, internationally renowned expert in the field of stratification research, will discuss "Inequality by Design: Myths, Data and Politics." Author (with five Berkeley colleagues) of Inequality By Design: Cracking the Bell Curve Myth (Princeton University Press, 1996), Hout challenges the claims of the bestseller by Richard Herrnstein and Charles Murray, The Bell Curve, through a re-analysis of the very data used by Herrnstein and Murray to support their assertion that inherited differences in intelligence explain inequality.
Hout's talk will draw upon some of the recent work on the sources of inequality in the United States and assess the arguments of The Bell Curve. The lecture is open to the public.

To most folks, wetlands are marshy ponds with a duck or two floating on the water.
To Robert Brooks, associate professor of wildlife ecology in the School of Forest Resources, "all wetlands are not created equal," and the results of a three-year study of 51 natural wetland sites in Pennsylvania have shown this to be true.
Brooks, director of the Penn State Cooperative Wetlands Center, said Pennsylvania is losing hundreds of acres of wetlands per year to development and other uses. Simultaneously, state agencies, private companies and private citizens are restoring or creating hundreds of wetland acres each year. The project, funded by the Pennsylvania Department of Environmental Protection and the U.S. Environmental Protection Agency, Region III, gives agency employees and other professionals specific guidelines to describe and categorize a variety of wetland types, including natural wetlands used as reference sites for researchers and mitigation projects.
A series of assessment techniques to help professionals evaluate restored or created wetlands have been developed during the study. "A wetland is an elusive thing to categorize," Brooks said. "The best way to describe our work is that we are creating a sort of template or blueprint that can best match the characteristics of a certain type of wetland to the site where you intend to replace or restore a wetland."
The project identified 51 sites as reference wetlands and categorized them into types. At each site, characteristics such as plant life, animal life, soil composition, sedimentation and basin shape also were analyzed and categorized.
"The project also extensively researched bird, amphibian and plant species that inhabit only certain wetland habitats -- called indicator species," Brooks said. "To truly create or restore a wetland in a specific site, you have to match the structure and characteristics of whatever wetland type best fits the site. Otherwise, the wetland will function differently."
Brooks said forested wetlands fed by groundwater are the most abundant type of wetlands in the Mid-Atlantic area, and these forested areas are most commonly lost to development. If the forested wetlands are restored or created, the most common type is an open-water pond with emergent forest vegetation.
"The flora and fauna associated with forested wetlands and open-water wetlands are markedly different," Brooks said. "What this means is that some types of wetlands will be very hard to replace, and if the choice comes down to destroying a wetland, it's important to know which types can be difficult to replace."
The team's research also revealed that while different types of wetlands obviously have different characteristics, created wetlands have different characteristics from the wetland types they are modeled on. "A created wetland looks like a natural site, but it really doesn't behave like one," he said.
Although Brooks said the wetlands assessment project has given resource professionals the tools with which to identify or describe wetland types, the next step to completing the portrait of the state's wetlands is understanding how wetlands function.
To do this, the Penn State Cooperative Wetlands Center is initiating another three-year wetland project, led by Brooks and C. Andrew Cole, affiliate assistant professor of landscape architecture, designed to discover how wetlands function, including how wetlands change over time and how human disturbances affect their natural progression.

Sure, you can let your mouse do the shopping on the World Wide Web or you can stroll a virtual mall, but those conveniences are last week's e-news. What if you or a corporate consumer could use the Web to save real time and real money? And, what if the seller could learn to serve customers so well that they would come back time after time?
Supported by an IBM grant of $63,000, a cross-disciplinary team of researchers is trying to create a system to do just that. Plus, one part of the program may even help consumers eat more healthfully. The primary thrust, though, is to capitalize on the power of the Web and database technology to create what is being called a "21st-Century Customer Management System."
Using this system, a customer could, for example, quickly and effectively explore the features and cost tradeoffs between two types of laptop computer, then place an order without reams of order forms and paperwork. Or, a customer could call up a company Web site and, by filling out an electronic form, say, "This is my problem, what can you do for me?" Web images of the products would permit a thorough visual inspection of critical features.
At the same time, the laptop computer seller could learn about the customer's likes and dislikes, using that information to better serve the buyer in the future, speed transactions, compile preferences for new designs, and build a closer, long-term relationship between the buyer and seller.
Involved in the project are David T. Wilson, holder of the Alvin H. Clemens professorship of entrepreneurial studies, Anthony Verstraete, senior lecturer in management information systems, and Stanley Aungst, instructor in management information systems, all with The Smeal College of Business Administration; Audrey N. Maretzki, professor of food science and nutrition, and Janice McClure, research support associate, both in the College of Agricultural Sciences; and Russell Barton, associate professor of industrial engineering, in the College of Engineering.
The goals are to reduce the steps and extraneous cost in a sales transaction, making it easier and quicker for customers to get what they want. At the same time, sellers can learn about the buying habits of their customers so they can do a better job of delivering what they need. Researchers are also exploring the possibility of working with a grocery chain, setting up a system whereby seniors living in a retirement community or low-income consumers in a public housing development could jointly order groceries over the 'Net and have deliveries made right to their home. Costs could be lowered through potential savings in delivery expenses. The Web ordering system also could be set up to display nutritional information on each product as the customer sorts through the selections on the aisles of the electronic market. A prototype of the system is expected to be complete by June.
