Gary Bishop, Enabling Technology (September 26)

How can computer geeks make life a little better for people with disabilities? How can you help? We will examine a few ways that computer technology is used to enable people to participate more fully in play, education, and work.

Gary Bishop graduated from the Southern Technical Institute in Marietta, Ga., with a degree in Electrical Engineering Technology in 1976.  After working for two years in the electrical power industry as a COBOL programmer, he came to UNC-Chapel Hill in 1979 to pursue graduate studies.  As if graduate studies weren’t enough, for his first two years as a graduate student here, he managed the Department of Computer Science in what is now the job of Associate Chair for Administration.  He completed his Ph.D. in Computer Science at UNC-Chapel Hill in 1984.  After working in industry at AT&T Bell Labs and at Sun Microsystems for several years, he joined our computer science faculty in 1991.


Ryan Brown and Marcia Bradshaw, Digital Divide (October 10)

The digital divide is the gap between those with regular, effective access to digital technologies and those without. It is related to social inclusion and equality of opportunity. It is seen as a social/political problem and has become increasingly relevant as the industrialized nations have become more dependent on digital technologies in their democratic and economic processes.  With regard to the Internet, ease of access is a fundamental aspect, but it is not the sole factor. Effective access also depends on ability to use information and communications technologies effectively.  The digital divide is often discussed in an international context because of the widely varying social and economic conditions in different countries.   Our speakers will discuss the digital divide in both international and local contexts.  Ryan will discuss the work of a UNC club, Technology without Borders, that is working to bring technology outside the country and Marcis will discuss work to close the digital divide in Durham.
Ryan Brown graduated from Enloe High School in Raleigh, with a National Merit Scholarship. He is currently a Junior at UNC-CH, studying Psychology and Pre-Med. Technology Without Borders was founded by Ryan Brown, Betsy Matthews, and Clark Letterman in November, 2005. Ryan spent a month in Mexico on a TWB project in the summer of 2006 teaching computer education to over 130 students, ages 6-50.
Marcia Bradshaw  is project director of the Environmental Science program at NCCU as well as project director of TOP-CAT, Technology Opportunities Program-Community Access to Technology.  The TOP-CAT project is a non-profit orgranization seeking to provide access to and promote the effective use of digital technologies so that under served neighborhoods in Durham, North Carolina may work to resolve the many challenges that adversely effect their quality of life.

Mary Whitton and Daniel Ward, Games (November 1)

Tonight's topic covers two radically different aspects of games:  how they can be used to the benefit of people and society and how they can cause addictive problems.

It took computer games to drive the market so that interactive 3D graphics down so that it is a part of every computer now.  Serious applications--from training to policy decision making--are the beneficiaries of the ubiquitous graphics capability.  Through examples, Pro. Whitton will discuss the technology that enables games, some technical issues still hindering serious game development, and some recent research that illustrates how subtlly content can influence behavior.

Have you ever been addicted to anything?  Shopping?  Gambling?  Sudoku?  How about the Internet?  Meet someone who never thought he could get addicted to anything, especially role playing games on the Internet.  We will analyze how his addiction started and what have been the consequences of his gaming addiction.

Mary C. Whitton has been involved in the development and evaluation of high performance graphics, visualization, and virtual environment systems for over 25 years.  She is a Research Associate Professor in the Department of Computer Science at the University of North Carolina at Chapel Hill.  Her research focuses on understanding what makes virtual environment systems effective and on developing technology and techniques to make them more effective.  Ms. Whitton joined UNC after 16 years in industry.  She was a co-founder of Ikonas Graphics Systems and Trancept Systems (acquired by Sun Microsystems).  She was President (then called Chair) of ACM SIGGRAPH 1993-1995.  Ms. Whitton earned an M.S. degree in Electrical Engineering from North Carolina State University. 
Daniel Ward
Daniel Ward is a 2001 graduate of UNC-Chapel Hill, and majored in Geography.  He is currently a Doctor of Pharmacy candidate at Wingate University School of Pharmacy, located in Wingate, NC.  In his spare time (haha..spare time), Daniel likes to play piano, read, and play tennis.  Upon graduation in Spring 2007, Daniel plans to work in community pharmacy in Eastern NC.

Andrew Chin, Antitrust and Microsoft (November 14)

Prof. Chin will discuss one of the most analytically demanding legal questions in antitrust history: the Microsoft tying claim.  In analyzing that claim, the parties, the courts, and most previous commentators failed to formulate a precise definition of a software product, and heavily relied on the false and misleading intuition that a software product consists of software code.  Chin will review the D.C. Circuit's adjudication of the Microsoft tying claim and reaches different legal conclusions by applying more precise techniques of antitrust analysis, grounded in first principles of antitrust law, copyright law, and software engineering, to the facts proven at trial.  These conclusions indicate that the courts should have found Microsoft liable for illegal tying under any of the doctrinal alternatives they considered for adjudicating the claim.  Instead, harms to competition from Microsoft's tying conduct that were factually proven at trial have gone unremedied, and Microsoft now enjoys illegitimately acquired monopoly power in the market for Web browser software products.

Andrew Chin
After serving as student government president at Texas, Chin earned his doctorate studying combinatorial mathematics and computational complexity theory at St. Catherine's College, Oxford on a Rhodes Scholarship and a National Science Foundation Graduate Fellowship. Between 1991 and 1995, he taught mathematics at Texas A&M University, computer science at King's College, University of London, and public policy at the University of Texas at Austin. At Yale, he published a paper written during his first semester as a note in the Yale Law Journal, and several subsequent law review articles. After graduation, he clerked for Judge Henry H. Kennedy, Jr. of the United States District Court for the District of Columbia, and assisted Judge Thomas Penfield Jackson and his law clerks in the drafting of the findings of fact in United States v. Microsoft Corporation. Chin then practiced in the corporate and intellectual property departments in the Washington, D.C. office of Skadden, Arps, Slate, Meagher & Flom, LLP. He is of counsel to Intellectual Property Solutions, P.L.L.C., where he prepares and prosecutes patent applications in computer and Internet technology. Chin joined the faculty of the University of North Carolina School of Law in 2001. He teaches antitrust, intellectual property, and patent law.
