Text Box: Mathematics Department Newsletter
May 2003




It has been more than a year since the last Newsletter.  A few years back, we posted the Newsletter in May.  We have drifted that direction again.  The academic calendar seems to keep us so busy during the winter months.  This Newsletter will contain two full years of information for student activities.

This past year, Don Jurick passed away unexpectedly due to a heart attack in October 2002.  Don held a joint appointment since 1994; he taught in the Department of Mathematics and he served as the supervisor of MathSci Computer Learning Environment.  We remember Don in the final section of this Newsletter.

A number of proposed initiatives are beginning to develop.  I can discuss two here, a new program in financial mathematics and our efforts in Mathematics Education initiatives; I hope we will have more in next year’s letter. 

In March 2002, we were awarded a small grant from the Council of Graduate Schools/Sloan Foundation (CGS/Sloan) to perform a feasibility study with respect to a professional M.S. program in Financial Mathematics.  The Sloan Foundation challenges academic units in the sciences to develop professional M.S. programs to complement the MBA programs and the Management Science programs.  We have been working with the Departments of Economics & Finance, Computer Science, and Engineering Management & Systems to develop a program in Financial Mathematics.  Recently, we were awarded a second grant from CGS/Sloan to implement this program.  I have posted an announcement and a proposed curriculum at http://academic.udayton.edu/PaulEloe/FINMTH.htm for your perusal.  I am happy to take any input you might have.  We need to seek approval from the Ohio Board of Regents (OBOR); we are working with a calendar to admit students to this program beginning August 2004.

We are actively developing the Mathematics Education program for pre-service and in-service K-12 teachers.  Becky Krakowski, with a Ph.D. in mathematics education from North Carolina State University, came on board in August 2000.  We have successfully hired a new faculty member, Shannon Driskell, to begin working in the department in August 2003.  Shannon will earn a Ph.D. in mathematics education from the University of Virginia in August 2003.  With Becky and Shannon, we feel we are in a position to pursue exciting initiatives with respect to K-12 mathematics education issues.  This comes at a time when Wright State University (Ann Farrell (79) is on the faculty at Wright State) is developing a Ph.D. program in Mathematics Education.  The two programs don’t compete as we intend to support in-service teachers and Wright State will be preparing specialists for university positions.  The two programs should complement each other very nicely.  Becky, as Principal Investigator, recently coordinated a partnership with UD, Wright State, the Dayton Public Schools, and the Springfield Public Schools and proposed a Mathematics and Physical Science Professional Development Project for Secondary Teachers to the OBOR.  A partial list of the goals of the program are to enhance teacher understanding of content in mathematics and science, of research-based methods to improve student achievement, of effective use of technology in teaching, and of integration of mathematics and science.  Recently, the OBOR funded this $200,000 project.

We are in the construction stage of the renovated Science Center.  In early May, we moved out of the office spaces on the east side of Sherman Hall so the workers could move in.  The calendar says that we will move back into renovated office spaces in August and this phase of the project will be complete before classes begin in late August.  So, it is during the summer of 2003 that the long awaited dedicated Schraut Memorial Classroom will come to exist. 

We are in the process of planning the 4th Schraut Memorial Lecture.  This year we will organize a student conference in conjunction with the 4th Schraut Memorial Lecture.  In addition, we will host a dedication ceremony for the Schraut Memorial Classroom.  We have scheduled these events for Saturday, November 1.  You will be informed as the plans develop.

Please contact me if you see anything misreported in this newsletter.  In an effort to use our financial and material resources wisely, many of you receive the newsletter electronically.  Visit the web site, http://www.udayton.edu/~mathdept/, (click on archives) to see the on-line version.

Conversations Among Women in Mathematics:


Conversations among Women in Mathematics was held during the morning on Saturday, November 2, 2002.  Wiebke Diestelkamp and Aparna Higgins organized the event with the help of a generous grant from The Women’s Center Programming Fund at UD.


The program was a rousing success, fulfilling goals of bringing together women in different stages of their mathematical careers, promoting interaction between these women on both mathematical and gender-related issues, and providing examples of UD alumnae who are in positions of leadership in their professions.  The program took the form of a panel discussion on women in mathematics, followed by a luncheon.


Forty people participated in Conversations among Women in Mathematics.  There were 13 alumnae (three of whom are also current mathematics faculty, and one is a high school teacher), seven women faculty from the Department of Mathematics, nine women high school students, four high school mathematics teachers, 11 undergraduate UD students (9 of them women), three women graduate students, and a couple of male alumni and faculty.  We are grateful to the Mathematical Association of America, the Association for Women in Mathematics and the American Statistical Association for providing us with free or inexpensive information on careers and professions that use the mathematical sciences.  We included these (along with information from various UD offices) in the registration packets for the participants.


The panelists were Marla Gross (’90), Senior Statistician, P & G, Cincinnati, Nancy Roderer (’68), Associate Professor in the Division of Health Sciences Informatics and Interim Dean of University Libraries, Johns Hopkins University, Julie Suwalski (’92), Mathematics Teacher, Northmont High School, Clayton and Kathleen Taylor (’65), Professor of Mathematics and Assistant Chair of the Department of Mathematics and Computer Science, Duquesne University.


Each panelist spent 10-15 minutes talking about her experiences as a woman in mathematics and as a graduate of our department. Each woman provided some background as to why she chose mathematics to study, and how she has benefited from that pursuit.  The overwhelming reasons for going into mathematics were the encouragement and examples of fathers, uncles or teachers, and the benefits always included the ability to think critically and logically, and to develop problem-solving abilities.  The audience asked many questions about the panelists' jobs, about recruitment and retention of women in mathematics careers, about keeping one's options open even as one prepares to become a high school teacher, about which mathematics classes would be most useful to take in college, and about balancing careers with families.  In fact, the conversation was so lively that we had to interrupt it and request that we continue it in a new venue -- the Barrett dining room -- where luncheon was arranged for us. We had arranged the seating so that every table had a mix of high school students, college students, college faculty and alumni. The conversations at the tables never lagged.  After lunch, most of the participants attended the Biennial Alumni Seminar and the Annual Schraut Memorial Lecture.


With such a successful first-run, we hope to be able to make this a biennial event.  There certainly seems to be a need for women in mathematics to get together and celebrate their connections to each other and to mathematics, and to network with each other. 




20th Biennial Alumni Seminar:


The format was much the same as in previous years.  We opened with a single session and then broke to parallel sessions in which students could meet with alumni/ae from particular professions.  We broke into 8 parallel sessions this year.  The sessions were:


Mathematics & Business                                   Mathematics & Engineering

Coordinators:                                                     Coordinator:

Tom Britt, Teri Trimbach Dean                     Ed Mykytka


Mathematics & College Teaching                       Mathematics & Statistics

Coordinators:                                                     Coordinators:

Paul Campbell, Kathy Taylor                         Kristin Blenk Duncan, Tom Filloon


Mathematics & Service                                     Mathematics & High School Teaching

Coordinators:                                                     Coordinators:

Susan Pratt, Charles Stander                                     Becky Krakowski, Scott Mitter


Mathematics & Medicine                                   Mathematics & Others

Coordinator:                                                      Coordinator:

Dan Schauer                                                    Nancy Roderer


An important message to give to students is that a strong background in mathematics truly opens doors to opportunities.  The session, Mathematics & Others, is not imaginatively named.  Hopefully we will do better by the 21st Alumni Seminar.  Nancy Roderer serves as an Associate Professor in the Division of Health Sciences Informatics and Interim Dean of University Libraries at Johns Hopkins University.  She was a very good sport with the title of her session; she had much to say about the role of Information Technology in the world of Library Science.

In the single session that preceded the parallel sessions, several of the session coordinators gave short presentations to entice students to their sessions.  Due to time constraints, Mathematics & Teaching and Mathematics & Statistics did not make presentations.  The presenters were:  Nancy Roderer (see the above paragraph), Tom Britt, who is an actuarial scientist with Nationwide in Columbus; Teri Dean, who has held several management positions with P & G in Cincinnati; Ed Mykytka, who chairs the Engineering Management & Systems program at UD; Susan Pratt, who works with the database for a nonprofit organization in Columbus; and Dan Schauer, who is an Outcomes Research and Clinical Effectiveness Fellow in the Cincinnati College of Medicine.  He serves as his research group’s statistician.  As we put the day’s events together, we intended that students see the diversity that mathematics brings.  The common themes of statistics and database management through these presentations were remarkable.  The UD faculty has much to learn from these sessions as well.


Third Kenneth C. Schraut Memorial Lecture:


Following a social break, Dr. Paul J. Campbell (67), delivered the 3rd Kenneth C. Schraut Memorial Lecture.  After receiving an M.S. in algebra and a Ph.D. in mathematical logic from Cornell University, he taught at St. Olaf College in Minnesota before settling at Beloit College in Wisconsin where he is currently Professor and Chair of the Department of Mathematics and Computer Science.  He has been the Reviews Editor for Mathematics Magazine since 1977, editor of The Undergraduate Mathematics Applications Project (UMAP) Journal since 1984, and author for many years of annual articles on mathematics for Encyclopædia Britannica yearbooks.  Paul delivered a very enjoyable lecture on How to Keep Up with Mathematics.  The slides and references for his talk can be found at

Qin Sheng delivered colloquium presentations at Western Illinois University, the University of Louisiana, Lafayette, and the National University of Singapore.  He was an invited speaker at the Second International Conference on Neural, Parallel and Scientific Computations in Atlanta as well.  Qin co-organized with Paul Eloe a Special Session in Nonlinear Analysis and Computation, Bloomington, Indiana, April 2003.  Qin, Muhammad Islam, Mariette Maroun, and Youssef Raffoul gave talks.  Eric Kauffmann (91), currently an associate professor at the University of Arkansas at Little Rock, also delivered a lecture in this session.


Departmental members continue their service to the mathematics community.  Bill Friel continues as Secretary-Treasurer of the Ohio Section of the MAA, and Tom Gantner served as the Ohio Section’s Past-President and Chair of the Teaching Awards committee.  Aparna Higgins continues as a co-director of  Project NExT, and serves on several committees of the MAA, including the Committee on Site Selection, the Committee on Professional Development and the Alder Awards committee.  She was elected to the Nominating Committee of the MAA, and completed her term on the subcommittee on undergraduate research. 


SABBATICAL:  Gerry Shaughnessy spent the entire 2001-2002 academic year on sabbatical leave.  Gerry spent a large part of time on sabbatical working as a statistician for UDRI.  He worked with a team on a project that is developing procedures for Retrogression and Re-Aging (RRA) of corrosion prone aircraft parts.  His efforts focused on statistically designing experiments to support the project.  He developed a model to predict tensile strength from an in-situ RRA treatment; he presented these results at a meeting of the Canadian Research Council.


Now that Gerry has returned to the classroom, he incorporates this experience to participate in a large experimental project into the statistics classroom.  He worked on another project on sabbatical that he incorporates into the classroom.  He employed the Visual Basic Macro language within Excel to “unconfound” effects from experimental data generated by an orthogonal array with a small number of experimental runs.  Gerry is head coach for the UD handball team.  This has nothing to do with his sabbatical, but it is certainly newsworthy.




UNDERGRADUATE ACTIVITIES (during the 2001/2002 and the 2002/2003 years)


Putnam Exam

Mark Burky and Gayatri Gunda participated in the William Lowell Putnam Mathematical Competition in both 2001 and 2002.  They were joined by Joel Helton and James Goodman in 2001 and by Steven Abrams, Steven Buck, Kari Blaeser, and Christopher Ryan in 2002.


Mathematics Modeling Competition

A team of Mark Burky, Michael Grote, and Gaytri Gunda spent a weekend in February 2002 to participate in the UMAP Mathematical Modeling Competition.  In this competition, the team is given two problems on Friday at noon.  The team then chooses one problem and must complete the work with the envelope dated midnight, on the following Monday.  This year’s team produced “The Development of a Mathematical Model to make the Height of the Water Output of a Fountain a Function of Wind Velocity to Prevent the Spraying of Those Walking Nearby.”


High School Mathematics Competition

The MAA Student Chapter and the Pi Mu Epsilon chapter organize an annual high school mathematics competition.  This is an impressive undertaking.  In addition to writing the questions and checking the answers, the UD students seek sponsors to support lunch and T-shirts for the high school participants, and arrange an awards ceremony.  Julia Tosi coordinated The Sixth Annual University of Dayton High School Math Competition in March 2002, in which 140 high school students on 47 teams from 10 schools participated.  Kolleen Hryb coordinated the Seventh Annual Competition in 2003, which had 115 high school students on 39 teams representing 7 schools.  In 2002, students who wrote problems and prepared for the contest included Chris Bomba, Marcy Carew, Chuck DeRee, Shelly Franz, Gayatri Gunda, Mike Grote, Kolleen Hyrb, Stephanie Lindsey, Susan Pratt, and Chunlei Zhang. In 2003, these tasks were performed by Suzanne Dietz, Alisa Godfrey, Jason Inkrott, Stephaney Lindsey, Melissa Lovesky, David Martin, Peri Shereen,  and Becky Snyder.  Joining these students to help out on the day of the contest were David Martin and Tara Bertke in 2002, and Tony Ball, Gayatri Gunda, Laura Riepenhoff and Emma Stull in 2003.   David Martin designed the T-shirt each year, and in 2003 he also designed a logo for the Department of Mathematics.  Becky Krakowski (in 2002) and Stephanie Edwards (in 2003) were invited to address the participants.  Over the two-year period, the following organizations have provided their generous sponsorship of this competition:  the Department of Mathematics, the Honors and Scholars Program, the Office of Admissions, Food Services, the Bookstore, the Student Alumni Council – all from UD, and the Day Air Credit Union, The Greek House, Jimmy John’s, Papa John’s and United Dairy Farmers.



Gayatri Gunda participated in the George Washington University Summer Program for Women in Mathematics (SPWM) in the summer of 2002.  This is a five-week intensive program for mathematically talented undergraduate women who are completing their junior year and may be contemplating graduate study in the mathematical sciences.  During the summer of 2003:  Peri Shereen will participate in the SPWM at GWU; Pam Smith obtained an internship at Mission Research Corporation to work on parallel processing problems; Ben Johnson will attend an NSF-Research Experiences for Undergraduates program in physics at the University of Toledo; Kolleen Hyrb will be a resident assistant at the Pre-College Programs at Wright State University; Gayatri Gunda will study in Spain and compare K-12 education in the USA and Spain.

She delivered a beautiful eulogy at Don’s funeral mass.  With Sr. Donna’s permission, we close this newsletter with her eulogy.



In Memory of

Donald L. Jurick

Remarks delivered Wednesday, October 16, 2002


I’m Donna, Don’s sister, and as many of you know from him a Sister of Notre Dame. I’m grateful that Father Jerry asked me to say a few words on behalf of the family: brother, Fred, and sister, Peg, and her husband, Norm.


For me and I think for many of you “THE BIKE” has become a symbol. It says something of exploring new ground, of fragile, perhaps dangerous independence, frugality and more than a touch of mystery. It took him on paths through many neighborhoods and out into the countryside. I’m grateful to those of you who offered a ride when he, knowingly or unknowingly, needed one.


The 1st Neighborhood:

Math Sci:   Its students, faculty colleagues, and maintenance staff.  I know this neighborhood fairly well through late night phone calls. Many of you know it far better and will have to share your own stories.  Here, too, he sought to explore new ground or perhaps more importantly make it possible for students to explore new ground. The family read last night the touching notes written by students. That reaching out went beyond his own math class students and student fellows in the labs to a concern for education in general and at all levels.


The 2nd Neighborhood (but not in any hierarchical but rather a meandering order):

Family was important to Don sometimes in more mysterious than obvious ways.  We grew up close as siblings -- 4 of us less than 7 years apart from oldest to youngest.  Then as adults scattered throughout the U.S.  He deeply loved his nieces and nephews:

My sisters’ 4 children

My brother’s 2 children

His surrogate families after my parents died and we were all gone from the Dayton area were incredibly special to him and for him: bike rides, children’s football games, home cooked meals.


The 3rd Neighborhood

The Religious Community that nourished him spiritually.  Friends and acquaintances in Incarnation Parish: Sunday Mass, ushering, muffins and conversation.  The Marianist Spirit on campus: alive and important for him.  These were “water” for a hot or tiring or leisurely bike ride.


The 4th Neighborhood

The Intellectual Community that recognized and fed his need to grapple with and extend ideas.  The Faculty and Staff at the Research Institute who recognized his talent, took a chance on him and nurtured his development.  The Mathematics Department Chairs and Faculty who suggested he teach, bolstered his confidence and then allowed him to thrive and even become their teacher as technological innovations invaded the classroom.  Colleagues in the Sciences, the Education Programs, and the Center for Pastoral Studies all became collaborators in his work and theirs to further education for all students.  This brings me back to students, which in the end was his passion. I found on his desk a statement imbedded in a document (the intent of which I’m not quite sure) but the statement I think ties all the neighborhoods together:

My goals are to continue to create an environment in which students reflect upon what they are doing and naturally generate ideas, to provide the resources and guidance that allows them to develop and implement their ideas, to maintain a space where students learn that ideas can become reality. I strive to use technology to enhance education.  I want the students to situate what we are doing in a historical and philosophical context so that it is for the betterment of mankind. [I would say “humankind.” I think Don would even enjoy his big sister correcting him here.] Always in using technology in education I am concerned with its pedagogical value.

He somehow understood that students understood students best. And that our job as educators or mentors or parents was to free them and support them in their development of self and one another.


My brother, my sister and brother-in-law and I are deeply grateful for Don’s life and your

collaborative part in it. Your outpouring of kindness has been overwhelming. I pray with you that as the mystery of his life has touched each of us while he was among us, his spirit may challenge us to believe in and challenge one another and the generations that will succeed us.  May he rest in peace and yet may his spirit be restless enough to goad us on to even more life giving service.


Donna M. Jurick, SND
