The year has been one of multivariate comings and goings for the Mathematics Department. Professors Frank Morgan, Ollie Beaver, Stewart Johnson and Edward Burger were all on leave, working hard to make their times away successful and fruitful. (The prize for the largest number of different places visited during the sabbatical leave went to Professor Morgan.) We welcomed the arrival from Princeton of statistician Dick De Veaux. We look forward to the data analyses he will introduce us to and hope that now, with a statistician, we will all become Normally Distributed. Continuing the department tradition begun by Ed Burger, Dick regaled a big and enthusiastic audience at the annual Spring Family Weekend talk, "Sex, Lies and Graphical Displays: Making Statistics Work for You."
The department was also fortunate for the year's presence of Visiting Professors Rob Manning and Faan Tone Liu. Both made very successful and appreciated additions.
In the spring, Professor Dave Witte left Williams for the midwestern hills of Oklahoma State University, Stillwater, Oklahoma. We sincerely wish him good fortune and success, although we will sorely miss his cheer, counsel and never- stinting help and advice. Hardly a person in department has not benefited from insightful mathematical conversations with Dave. In honor of Dave's accomplishments at Williams, the department has instituted a new student prize: the Dave Witte (Mathematical) Problem Solving Prize.
We are all pleased to congratulate Professor Stewart Johnson on receiving tenure and his subsequent forthcoming promotion to Associate Professor.
In the midst of all the faculty activities, the department was delighted to welcome three little girl arrivals: Emily Silva, Alexa Adams and Alexandra De Veaux (in order of appearance). The proud parents allow us hold the newcomers on occasion, and we all agree that the three are most clever, smart and beautiful.
Continuing the theme of a year of many changes, Professor Cesar Silva was Acting Chair of the department in the fall and Professor Ollie Beaver took over as Acting Chair in the spring. Upon his return to Williams, Professor Morgan (in surprise to everyone) stepped down from the position of Chair; Professor Beaver has agreed to take over as Chair of the department.
The Mathematics department is very grateful for the years of leadership and untiring attention that Frank Morgan has given to Mathematics and to Williams since he arrived in 1987. As catalyst, as active prodder, as mathematics enthusiast extraordinaire, Frank Morgan liberated the enthusiasm and spirit that we all had for mathematics at Williams and led us into a new era of achievement. The surge of activity in and tremendous success of undergraduate mathematics research at Williams, from SMALL (an acronym whose original definition only a few know any longer) to independent study, have largely been results of Frank's efforts. Faculty teaching and research have thrived under Frank's unflagging encouragement and support. His continued enthusiastic support of ideas and innovation led to new and exciting courses and unique approaches to old courses. The number of mathematics majors has, as of this year, quadrupled the numbers of ten years ago. Indeed, Frank's indefatigable efforts on behalf of Williams College in the mathematics community has brought the department national recognition. We thank you Chair Frank!
Mathematics majors had a terrifically successful year. Four present and past majors were honored by the National Science Foundation: Chris French `95, Jessica Baraka `91, Anna Bardone `91 all received NSF grants; Michael Pelsmajer `95 received honorable mention. At the annual spring math majors dinner, the Rosenberg prize for outstanding senior went to Chris French; the Morgan prize for accomplishment and promise in applied mathematics went to Jeff Bevelander; the Goldberg prize for the best senior colloquium went to Chris Kollett. Additionally, the Benedict prize for outstanding sophomore went to Jason Schweinsberg (first place) and (second place) to Deborah Greilsheimer and Brian Wecht.
This year's SMERSH did not have the "fortune" of helping interview job applicants, but kept busy helping the department gather student opinions, running the fall and spring Ice Cream Socials and generally being available for giving advice and help. Thanks go to Emily Shahan `95, Ted Welsh `95, Aaron Williams `95, Dan Ebert `96, Teon Edwards `96 and Joanna Barnes `97.
Of course, very little could have been accomplished this year without the glue that holds the department together, Marissa Barschdorf. As the departmental secretary, Marissa is simply super! Patiently and cheerfully she gets us through deadlines, crises and the daily big or little details that crop up. We are very glad and grateful that Marissa is in the department.
All of the faculty had a busy and productive year. Highlights of the year's faculty activities are:

She also serves on the Advisory Board of the Williams College Multicultural Center. Beaver will become Chair of the Mathematics department.
Professor Deborah Bergstrand gave a talk on graph coloring as part of an alumni seminar at Williams in October. She also completed her third year as Dean of First Year Students -- her fifth and final year in the Dean's Office. She looks forward to spending her upcoming sabbatical at Stanford and then returning full-time to the Math Department.
Professor Edward Burger participated in the 1994 Math Science Event at Williams in May and presented "Proving Conjectures in Geometry Hands On". During the summer, Burger was the faculty research advisor for Colin Blakely `95 and Chris Kollett `95 who pursued original research in number theory. Both students produced manuscripts. Professor Burger then embarked upon a sabbatical leave.
In the fall, Burger was a Visiting Assistant Professor of Mathematics at the University of Texas at Austin. There he taught an undergraduate course in abstract algebra and was the faculty research advisor for D. Lucky. In the spring, Burger was a Visiting Assistant Professor of Mathematics at the University of Colorado at Boulder. There he taught an advanced graduate topics course in number theory and was a visiting member of the Center for Number Theory Research. At both Austin and Boulder, Burger interacted with some of the leaders in number theory research.
During his leave, Professor Burger gave numerous lectures around the country. In May he was the invited main speaker at the Mathfest at Bridgewater State University, Bridgewater, MA.

In November Burger was invited to lecture in the Millican Lecture Series at the University of North Texas in Denton. There he spoke on "Diophantine Approximation: So Close, Yet So Far".
In February at the University of Colorado at Boulder, Burger gave a lecture entitled "Primitive Bases, Siegel's Lemma and an Application" in the number theory seminar; and in the Mathematics colloquium he spoke on "The Good, the Bad and the Unusual: How to Build Amusing Transcendental Numbers by Procrastination". In March he was invited to address the entire student body at the San Domenico School in California. There he gave a talk entitled "Oops, Ouch, Wow, Hubba Hubba: How Guesses and Mistakes Lead to Beauty and Mathematics". In April, Burger was invited to give a lecture in the Humanities Lecture Series at Tacoma Community College in Washington. There he presented "How Well Does Our Intuition Capture Truth and Reality"? A Journey into the Aesthetics and Beauty of Mathematics".
Professor Burger was named a Mathematical Association of America Visiting Lecturer (1994-1997). He reviewed three articles for Mathematical Reviews and was the referee for both the Houston Journal of Mathematics and the Rocky Mountain Journal of Mathematics. His article, "Inhomogeneous Inequalities Over Number Fields" appeared in the Illinois Journal of Mathematics. His article, "Transcendence and Irrationality Measures" appeared in the Proceedings of the Seminar on the Theory of Numbers (Caen, France, 1994). His article, "Sur les quotients partiels de U-numbres dans un corps de séries formelles" co-authored with E. Dubois, appeared in Comptes Rendus de l'Acádémie des Sciences Paris..
Professor Richard D. De Veaux introduced two new courses into the Statistics curriculum this spring, Math 244 (Statistical Design of Experiments) and Math 346 (Regression and Forecasting). Next fall he will introduce the newly designed introductory sequence of Statistics courses comprised of Math 143 (Elementary Statistics and Data Analysis) and Math 243 (Statistics and Data Analysis). Math 143 is designed for students in the humanities and social sciences who wish to become literate in the language and basic manipulation of statistical analysis. Math 243, which covers many of the same topics as Math 143, is intended for science and Mathematics majors who may take the advanced statistics courses.
De Veaux has served as Program Chair for the American Statistical Association section on Statistics in the Physical and Engineering Sciences and as chair organized 5 invited paper sessions and 14 contributed paper sessions for the national meeting of the ASA in Orlando this Summer. With Lyle Ungar of the University of Pennsylvania he will teach a one day short-course entitled "An Introduction to Artificial Neural Networks" at the meeting. He continued his work as Associate Editor of Technometrics and has accepted a newly created position as Review Associate Editor for which his job will be to actively solicit and encourage review articles for Technometrics. He has been invited to be a discussant at this years Gordon Research Conference in Statistics in Chemistry and Chemical Engineering. His paper, "Multicollinearity: A tale of two non-parametric regression" (with L. H. Ungar appeared in Selecting Models from Data: AI and Statistics and a paper with H. Wainer "Making Triathlons Fair: The Ultimate Triathlon" appeared in Swim Magazine. In addition, several papers appeared in refereed conference proceedings. He has also received (tentative) notification that he has been awarded a National Science Foundation grant for two years for research on "Radial Basis Function Neural Networks in Process Control".
Professor Thomas Garrity has continued his collaboration with Robert Mizner. They finished a paper "The Equivalence Problem for Higher-Co-dimensional CR Structures". Their paper "Invariants of Vector-Valued Bilinear and Sesquilinear Forms" appeared in the journal Linear Algebra and Its Applications. In the fall he spoke at the College of the Holy Cross and in the spring he spoke at the Hudson River undergraduate Math Conference.
Victor E. Hill IV, Thomas T. Read Professor of Mathematics, gave his multi-media presentation "Mathematical Aspects of the Music of Bach" for a special meeting of the Northeastern Section of the Mathematical Association of America held at Regis College in October. He gave the same program twice in one day at Dartmouth College in November, and also presented it at St. Paul's School, at Williams, and for the St. Petersburg Chapter of the American Guild of Organists. He also served at St. Paul's School as Dickey Visitor in Mathematics, lecturing on many-valued logics, speaking informally to classes, and consulting with the Mathematics faculty. In June he was appointed to his 14th and 15th years on the Board of the Association of Anglican Musicians.
Professor Stewart Johnson is on sabbatical this year and continues his research in Dynamical and Hybrid Systems. He presented joint work at the Second Annual Hybrid Systems and Autonomous Control Workshop at Cornell University in October 1994. His recent paper, "Simple Hybrid Systems" has appeared in the International Journal of Bifurcations and Chaos.
Professor Faan Tone Liu was a Visiting Assistant Professor in the Mathematics Department at Williams this year. She taught first-semester Calculus, Multivariable Calculus and Real Analysis. She gave several seminars throughout the year at faculty colloquia and seminars, and a talk entitled "Decomposing Singular Measures" at SUNY-Albany. Liu studies Measure Theory and Classical Fourier Analysis.
Professor Robert Manning spent the year as a visiting professor at Williams. In addition to giving several talks at the Math Faculty Seminar and the Albany-Williams Ergodic Seminar, he spoke at the University of Maryland on "Quantum Computation by Sums of Classical Trajectories" and at the Hudson River Undergraduate Mathematics Conference on "A Random Pair of Sticks in a Square". His paper "Regularized semiclassical radial propagator for the Coulomb potential" appeared in the journal Physical Review A, and he continued to work on the implementation of quantum mechanical approximation methods to multi-body systems. He received a postdoctoral research fellowship from the National Science Foundation to study mathematical modeling and computation in chemical applications at the University of Maryland.
He developed a new curriculum for Math 305 (Applied Real Analysis) to address the needs of both math majors and students from the physics, chemistry, computer science, and economics departments. In his multivariable calculus courses, he designed projects giving students experience with realistic problems, computation on Mathematica, and technical writing.
Professor Robert Mizner continued his collaboration with Professor Thomas Garrity on algebraic theory and the geometry of CR structures.
Professor Frank Morgan enjoyed a year on sabbatical at Bonn, Germany; Vitoria, Brazil; Queens College, New York City; Davis, California; Melbourne, Australia; and Trento, Italy. Continuing his research on minimal surfaces, he published 6 papers and has 10 more in the works. A new edition of his Geometric Measure Theory book and a new text Calculus Lite are appearing this spring and summer. He has given some 50 talks, including a series of lectures on geometric measure theory at the International Center for Mathematics Research in Trento, Italy, and his popular Soap Bubble Geometry Contest at locations around the world, including his old high school in Allentown, Pennsylvania, where he was recognized as "Distinguished Alumnus" at the June graduation.
This summer Morgan's SMALL undergraduate research Geometry Group will study the shapes of crystals and immiscible fluids, participate in a regional graduate course taught by Morgan at Illinois, and speak at Morgan's special session on Soap Bubble Geometry at the joint Mathematics meetings in Burlington, Vermont. Other speakers include five other SMALL Geometry alums. Christopher French `95 and Scott Greenleaf will report on work from the summer of 1993; their joint paper with Morgan has been accepted for publication in the Journal for Geometric Analysis. The 1994 American Mathematical Society What's Happening in the Mathematical Sciences features earlier work on soap bubbles by the SMALL Geometry Group, including "The Standard Double Soap Bubble in R2 Uniquely Minimizes Perimeter" by Manuel Alfaro `91, Jeffrey Brock, Joel Foisy `91, Nickelous Hodges, and Jason Zimba `91 (Pacific J. Math.) and the recently published "The Shortest Enclosure of Three Connected Areas in R2" by Christopher Cox `92, Lisa Harrison `93, Michael Hutchings, Susan Kim `94, Janette Light `93, Andrew Mauer `93, and Meg Tilton `93 (Real Analysis Exchange .
In March Morgan represented Mathematics research at a exhibition for Congress on national science funding, accompanied by SMALL alums Michael Hutchings (now a graduate student in Mathematics at Harvard) and Susan Kim `94 (now with Teach for America in Los Angeles).
Morgan serves as a member of the Council of the American Mathematical Society and several national committees.
Professor Cesar Silva offered a tutorial, Chaos and Fractals, in addition to his regular courses and continued his research in ergodic theory; he was acting chair of the department for the Fall semester. In June he visited his collaborator Philippe Thieullen in Lisbon, Portugal and gave the following talk: "Quotients of Nonsingular Actions and Rational Joinings." He later went to a conference in Quito, Ecuador where he presented "Teoría ergódica de aplicaciones con medida cuasi-invariante" and "Sistemas Dinámicos Discretos: Fractales y Caos" at the IV Encuentro, Quito, Ecuador in July. He also lectured on the same topics at the Catholic University of Peru, in Lima. He presented "Coding techniques for ergodic nonsingular maps" at the University of North Carolina, Chapel Hill in the Ergodic Theory Seminar in March. He also gave a general survey talk at Siena College entitled "Does A Power of 2 Start With Your Social Security Number?" in their Mathematics Colloquium on December 2, 1994. He was a Workshop discussion leader at the Science-Engineering Academic Support Network organized by New England Board of Higher Education in Boston on October 2, 1994.
Professor Silva organized a weekly seminar in ergodic theory together with a colleague at the State University of New York at Albany, Professor Karin Reinhold-Larsson. He also gave several talks at Williams on fractals and ergodic theory. The second semester he supervised a student, Forrest Trepte, on a 3-D fractals rendering program.
Silva organized a Special Session in Ergodic Theory at the Hartford Meeting of the American Mathematical Society in March, where 19 speakers presented talks.
He had the following paper accepted for publication: "Prime type IIIl automorphisms: An instance of coding techniques applied to nonsingular maps", (with A. del Junco), and submitted the paper "Mixing conditions for nonsingular transformations", with T. Adams and N. Friedman. On May 19 together with Professor Beaver he attended a workshop on Mathematica in Champaign, Illinois.
Professor Dave Witte taught three new courses this year: an applied algebra course for junior majors, a senior seminar on problem solving, and a Winter Study course on how to use the computer program Mathematica. He was on leave for the spring, and used this opportunity to attend conferences and to visit several research universities. His paper on "Superrigidity of Lattices in Solvable Lie Groups" was accepted for publication in Inventiones Mathematicae.
Student-faculty research continues to be an important part of our program. This summer (`95) there are 12 students working full time on research projects including three from outside Williams. Eight of the students are being supported by a grant from the National Science Foundation's Research Experiences for Undergraduates program. The students meet regularly for informal conversation (and cookies), as well as more formal talks given by faculty or students. Those students doing experimental work take a short course on machine shop work and another on electronics.
Visiting Assistant Professor Andrés Corrada-Emmanuel spent the year developing a model he created to explain the superfluid 4He transition in aerogels. His theoretical studies consisted primarily of Monte Carlo simulations performed on the Power Mac 7100/88 recently acquired by the department.
Professor Corrada-Emmanuel attended a "Workshop on Superfluids in Aerogels" at Northwestern University in November 1994 where he gave an invited talk on his new approach to the experimentalists working on these novel gels. In addition, he was invited to speak at the general meeting of the American Physical Society in April 1995 on the results of his computer simulations. He is now in Pennsylvania State University working with Moses Chan, a leading experimenter in 4He superfluidity.
Professor Stuart Crampton received a new two year grant for $135,000 from the National Science Foundation Research in Undergraduate Institutions Program to support his research with cryogenic atomic hydrogen masers. With Dr. Donald McAllaster and Christopher Kim `95, he continued the study of motional narrowing of hyperfine transition resonances that was begun last year with Craig Epifanio `94. Crampton gave talks entitled "Semiclassical Hydrogen Atom Collisions" at the joint Harvard University and Smithsonian Astrophysical Observatory Atomic Physics Colloquium in December and also at Wesleyan University in March.
Crampton continues to serve on the Board of Directors of Research Corporation and as a consultant to the Sherman Fairchild Foundation Scientific Equipment Program. He also serves on the National Academy of Sciences Board of Assessment of the Physics Programs at the National Institute of Standards and Technology. He concluded his term on the Advisory Board to the Education Division of the American Institute of Physics (AIP) and commenced serving on the International Advisory Board for a 1996 international conference on Undergraduate Physics Education to be sponsored by the AIP and the University of Maryland.
As chair of the department, Associate Professor Kevin Jones devoted much of his attention this year to the hiring of two new faculty members. Sarah Bolton, currently at Berkeley, will be joining us as a regular assistant professor. For her thesis research she built an ultra fast laser system and used it to study how excitations in semiconductors are influenced by the dimensionality of the sample. She will be joining our active Lasers and Optics Group. Dennis Krause, currently at Purdue, will be coming as a three year visitor. His work has been on the theory of time reversal symmetry in atoms.
Patrick Frierson `95 worked with Jones to build a frequency stable diode laser for use in a laser cooling experiment. Jones spent the summer of `94 at the National Institute of Standards and Technology in Gaithersburg, MD investigating collisions between very cold (0.5 mK) atoms. Such slow moving atoms are strongly influenced by weak long range forces and thus are sensitive to interactions which are masked in higher energy collisions.
With support from the college's Tutorial Program, Jones developed a new tutorial course on Applications of Quantum Mechanics. We have found the tutorial format particularly well suited to upper level problem solving courses and now offer three courses in this format.
During this year, newly arrived Assistant Professor Protik Majumder acquired and tested apparatus which will be used in pursuing experiments in laser spectroscopy of heavy atoms such as lead and thallium. Using the technique of optical rotation, he and former colleagues have recently been able to make precision measurements of tiny weak interaction effects in atoms which violate parity or mirror reflection symmetry. These results were published in April in the journal, Physical Review Letters. These new measurements can yield important new information concerning the physical theory known as the Standard Electroweak model. Beginning in the summer of 1995 with several students, he will undertake a number of additional measurements of lead and thallium atomic structure, using both atomic vapor cells and an atomic beam, which will facilitate the interpretation of the parity violation experiments in terms of testing fundamental physics.
In August 1994, Majumder attended the 14th International Atomic Physics Conference in which he presented a poster entitled "Measuring Parity Nonconservation with a Single Trapped Ion". During the fall of 1994, he gave three seminars: "Atomic Parity Violation: High Energy Physics at 10-4 GeV" at Williams ; "What Atomic Parity Nonconservation Can Teach Us About Elementary Particle Physics" at Amherst College; and finally "Atomic Parity Nonconservation in Pb, T1, and Ba+: New Results and Future Directions" at MIT for the Nuclear and Particle Physics Seminar series.
Associate Professor Jefferson Strait is continuing his research on light propagation in optical fibers. His honors student Todd Stievater `95 built a laser with a cavity made entirely of optical fiber. Presently the laser produces light at 1.56 microns, a wavelength at which pulses of light called solitons should be able to propagate long distances with very little attenuation or dispersion. The immediate goal of this project is to mode-lock the laser, causing it to produce pulses of light about 10-12 seconds in duration. Since conventional photodetectors cannot resolve optical pulses this short, another honors student, Kira Maginnis `95, built a device called an autocorrelator to measure the pulse duration. Ultimately Strait plans to use this laser as a source of soliton pulses to study how solitons interact when they propagate in optical fiber. During the summer of 1995, Matt DeCamp `96 and Ben Evans `96 will join Strait to continue this work.
During the spring semester, Strait taught a new course, Physics 142, Physics Today. The title of the course is familiar to professional physicists, because it is the title of a publication that describes what is new in physics and in the profession. At Williams, Physics Today is a first-year course about the physics of the twentieth century (mostly). First-year students learned special relativity and were introduced to quantum mechanics and some applications.
In May, Strait attended the Conference on Lasers and Electro-Optics in Baltimore. Throughout the year, he reviewed papers for the American Journal of Physics. He also taught two short courses in optics at Universal Instruments, Binghamton, NY. Universal builds robotic machines used to assemble electronic circuit boards. Strait's students at Universal were engineers who design the optical systems that align electronic components on circuit boards. At Williams, Strait served as the pre-engineering advisor. In that capacity, he organized an engineering career panel in December.
Professor William Wootters worked with four students in the summer of 1994 on theoretical problems concerning the processing of "quantum information," that is, information stored in systems that must be treated quantum mechanically. He continued this line of research throughout the academic year with his thesis student Colin McCormick. During a spring semester sabbatical Professor Wootters collaborated with a group at IBM's Watson Research Center working on quantum computation. He has given talks on his research recently at Swarthmore, Wesleyan, and SUNY Albany, as well as at IBM. At Williams he gave a different sort of talk, to the entire first-year class, at the beginning of the fall semester; it was entitled "Science and Mystery" and was based on readings by Freeman Dyson and Annie Dillard.
Professor Wootters was recently appointed to the editorial board of Physical Review A and attended a meeting of that board in May. He gave talks at two conferences this year, one at the University of Maryland on the foundations of quantum mechanics, and another at NIST on quantum computation and quantum cryptography. At a meeting of the Council on Undergraduate Research, he participated in a panel on NSF-REU programs at undergraduate institutions.
Staff Physicist and BSC Coordinator Bryce Babcock spent several weeks during the fall semester in South America where he was collaborating with Professor Pasachoff of the Astronomy Department, on experiments at the total solar eclipse in Putre, Chile on November 3, 1994 (see more detailed comments in the Astronomy section.) On his return trip he gave a talk on the eclipse experiment at the University of the Andes in Merida, Venezuela. Pasachoff and Babcock are preparing to repeat one of the experiments, looking for evidence of oscillations in small coronal loops, at the next total eclipse on October 24, 1995 in Mukandgarh, India. In addition to his continuing work developing research and instructional laboratory apparatus, Babcock has been involved with planning for the expansion and renovation of the science facilities as a member of the divisional committee that selected the architectural firms that will carry out the project, and as a member of the Science Facilities Building Committee which is overseeing the project. He attended a Project Kaleidoscope workshop on Facilities for Undergraduate Science and Mathematics Programs in Washington, D.C. in February.
David Park spent most of the year writing a book on light. In November he gave an invited lecture, "A Study of Time" at the World Archaeological Congress in New Delhi.

[Colloquia are held jointly with Astronomy. See Astronomy section for additional listings.]
The Psychology Department enjoyed a productive academic year with continuing scientific accomplishments of our faculty and many of our talented senior majors. Our faculty sponsored 7 senior honors theses that were presented to the department on May 15. Two of our faculty members also sponsored 3 senior honors theses in the Neuroscience concentration. Each of the student authors received honors, and five were subsequently elected to student membership in Sigma Xi. In addition, a number of current and former majors presented papers, co-authored with our faculty, at professional meetings held in this country and abroad. The titles of these talks can be found in the descriptions of the faculty's research.
We were also very pleased by the continued student interest in our department. This year, as in the next, we will have approximately 110 junior and senior majors. Not surprisingly, this substantial number of majors was accompanied by a large number of total registrations in psychology. We are delighted, of course, to know that the pedagogy and intellectual interests of our faculty appeal to many Williams students.
We are fortunate next year to have the capable services of two lecturers. Dr. Wendy Penner will join the Psychology senior seminar team this fall, and Dr. Anthony Giuliano, a visiting lecturer from the Family Center of the Berkshires, will be here for the full year teaching the courses in abnormal psychology during Professor Heatherington's leave.
This year we bid farewell to Susan Engel, a colleague who for several years has assisted the department on a part-time and full time visiting lecturer basis. Susan will be taking on a full time faculty position at Bennington College this fall. Her presence will be missed.
We had another year of informative outside colloquia. Dr. Richard Reckman spoke to the Psychology 401 class about his clinical experiences with multiple personality disorder. Our 1960 Scholars Program, designed to encourage students to consider academic careers, was very successful. The program brought eminent psychologists to campus to present colloquia on their research. Each colloquium was followed by a discussion and dinner with senior majors who had been selected as 1960's scholars. The speakers and their topics are listed at the end of this section.
Our department also had the exciting opportunity to introduce and moderate a lively on-campus debate between Dr. Charles Murray, co-author of The Bell Curve, and Dr. Robert Sternberg, a Yale University psychology professor who specializes in the study of intelligence. The attendance at this debate was overwhelming and included students, faculty, staff, and members of the local community and news media. The newly formed Applied Psychology Interest Group sponsored an open discussion and made readings available on reserve at the libraries for those interested in reading pertinent materials prior to the debate.
The Applied Psychology Interest Group also organized a group discussion and show of the Amalia Mesa-Bains exhibit at the Williams College Museum of Art. Dr. Bains is a noted psychologist and artist.
Once again, our majors made substantial contributions to the governance of the department. The Psychology Students Liaison Committee (SLC) continued to play an important role in representing majors to the department. We are also grateful to a number of our majors who served as teaching assistants in several of our larger courses and in the computer lab of Psychology 201, Statistics and Experimentation.
The Department maintained its close association with the Neuroscience Program, chaired by Professor Solomon. The Neuroscience Program continues to benefit from a generous grant from the Essel Foundation that supports student and faculty research in the neurosciences. The primary purpose of this award is to involve students in state-of-the-art neuroscience research. During this past summer, 12 Williams students were selected as Essel fellows and spent the summer working in the four neuroscience laboratories on campus. They were involved in diverse projects ranging from the investigation of spinal cord regeneration in fish to testing anti-dementia drugs in Alzheimer's patients. Many of these students will continue as either honors thesis or independent study students during the 1995-96 academic year. Additionally, five high school students were selected as Essel fellows. These students rotated among the neuroscience laboratories during their 6 week tenure. One of the goals of the Essel foundation was to bring distinguished scientists to campus for extended visits. This year, we were fortunate to have Dr. Susan Fahrbach who conducted a series of seminars on "The Neurobiology of Development."
Assistant Professor Carmen Arroyo conducted research on resilience processes among economically disadvantaged adolescents and social identity theory. In conjunction with her thesis student, Kristen Harrington `95, Prof. Arroyo began a new series of studies investigating the role of self-stereotypes in the use of self-handicapping impression management strategies. In October 1994, she was invited to attend and present a paper at the Children's Defense Fund Task Force on the Status and Psychological Development of African-American Males Conference in Tennessee ("Defiers of Negative Predictions: How Some African-American Males Succeed"). She also presented a paper at the April 1994, Annual Meeting of the American Educational Research Association entitled, "The Constitutive Role of the Self in Educational Resilience Among Economically Disadvantaged African-American Adolescents."
Professor Phebe Cramer continued her research work on the study of defense mechanisms. During 1994 and 1995, she attended the Austen Riggs Center, Staff Reunion in October 1994, and the Nag's Head Conference on Personality and Social Psychology in Highland Beach, Florida in June 1995. At Nag's Head, she attended a workshop on "Multiple Regression for ANOVA Users" and presented a paper on the pre-school antecedents of adult defense mechanism use.
Her professional activities during this year included service on the Institutional Review Board at the Austen Riggs Center in Stockbridge, continuation as the Associate Editor for the Journal of Personality, as a member of the Editorial Board of the Journal of Personality Assessment, and as a reviewer for articles submitted to other professional journals. Professor Cramer began collaborative research this year with Professor Gisela Labouvie-Vief, of Wayne State University, and continued her collaborative research with Professor Jack Block of the University of California at Berkeley. While on a half-year sabbatical this year, Professor Cramer traveled to Ecuador, the Galapagos Islands, Belize, Honduras and Guatemala, taking part in the study of indigenous flora, fauna, and culture.
