Math:MinutesWELCOME TO THE 2003-2004 ISSUE OF THE DEPARTMENT NEWSLETTER.The past year has been a sad one, with the untimely death of Joaquin Bustoz following complications from a car accident in early July. His presence in the Department is over-whelmingly missed. This followed the announcement earlier in the year that Joaquin hadbeen awarded a Presidential Award for Excellence in Science, Mathematics, and Engineering

Mentoring in conjunction withthe SUMS Institute; he is theonly recipient in the history ofthese awards to be so honored twice, with an earlier

award in 1996. Our thoughts continue to accompany his family at this time of bereavement.Articles later in the Newsletter by John McDonald and Katie Sisulak contain a fuller appreciation of just how great an impact Joaquin had upon the Department and Universityduring his tenure at ASU.

Yang Kuang continues to act as Director of Graduate Studies, GlennHurlbert as Director of Undergraduate Studies, and Matt Isom asDirector of First Year Mathematics. Harvey Smith retired in Januaryafter 25 years of service to ASU, and Lynn Kurtz in May, after 35 yearsat ASU. Both served their Department and profession with expertise,good humour, and grace. We shall miss their distinctive and muchappreciated contributions to Department life.

The current hiring season allows us to seek four future faculty, twoappointments joint with the School of Life Sciences, in ComputationalBiology and in Statistics, and two appointments within the Departmentin Analysis and in Statistics. We hope for a successful search.Congratulations are offered to John Lopez and Alex Mahalov upontheir thoroughly well deserved promotions to Full Professor. In the First Year Math programwe welcome Roger Cooper, John Pariseau, and Thistle Stacks, as new Instructors. RoseannRevel has had to take early retirement from her position in charge of the Testing Centre, dueto health reasons. She will be retiring to Montana, and we wish her lots of cool temperatures. Her winsome personality and wonderful sense of humour will be greatlymissed. Kristine Murray is taking over Roseann's responsibilities in the Testing Centre.

Sharon Lohr in June 03 had the signal honour of becoming the first recipient of theGertrude M. Cox Award, recognizing her important national contributions to statistics.Marilyn Carlson was appointed interim Director of CRESMET at ASU, reflecting the recognition of the fundamental role she is playing in ASU's educational mission. Severalconferences at ASU have been organized by faculty during the past year. Eric Kostelich andYing-Cheng Lai hosted the third ``Dynamics Days'' meeting in January; Dieter Armbruster ran a workshop on Transport in Supply Chains, Traffic and Biology, in February; ChristianRinghofer arranged a workshop on nanoscale devices at the end of October; and MarilynCarlson was in charge of the 7th RUME (Research in Undergraduate Mathematics Education)Conference also at the end of October.

April 2003 was Math Awareness Month, andcelebrated the interplay of Mathematics andArt. Festivities culminated with a lecture presented jointly by Helaman and ClaireFerguson, on the mathematics of Helaman'sinternationally acclaimed sculptures (his latestcommission is an 8-ton granite sculpture forthe headquarters of Merck Pharmaceuticals).The multimedia presentation was stimulatingand well-attended with over 300 people inthe audience, including many localhigh-school students and their teachers. Also

as part of the Month's activities, we were fortunate to have on display in theDepartment a selection of anamorphic art byASU's own graduate student Kelly M. Houle,whose art has an international following. Shewas a speaker at the M.C.Escher CentennialConference held in Rome, 1998. Her pieces,constructed so as to present recognizableimages when viewed in a cylindrical mirror,provoked great interest. She spoke on herwork to an intrigued audience.

The department is delighted to have receivedan extremely generous benefaction thatallows the formation of the Jack HawesMemorial Scholarship, funding an undergraduate student to work with a facultymember on a research project for one year.The Joaquin Bustoz Memorial Scholarship hasalso been exceptionally well endowed, andwill be offered for the first time this year. TheCharles Wexler Mathematics Prize for excellence in undergraduate study was awarded jointly this year to Andrew Jenningsand Joshua Kantor. Both students exhibit firstrate talents in mathematics: Jennings was alsothe recipient of the Department's prize forwork stemming from his Research Experiencefor Undergraduates. The Charles WexlerTeaching prize was awarded jointly to HeleneBarcelo and Anmin Zhu, recognizing theirexcellence in the classroom. Congratulationsto both. I never cease to be amazed at theenergies and enthusiasms of all my fellow colleagues and staff members as everyonestrives in their individual way to contribute tothe success of the Department at ASU. It is apleasure to be associated with you all!

Letter from the chair (continued from page 1)

Dr. Joaquin Bustoz passed away inAugust after sustaining serious injuriesin a car accident in July. Dr. Bustozleaves behind his wife, Maureen andhis children: David, Matt, and Sara.He also leaves behind three grandsons:Kyle, Alex, and Michael. Dr. Bustozwas a very caring father, husband, andbrother to his family.

Professionally Joaquin was known forhis work with Analysis, OrthogonalPolynomials, and SpecialFunctions. He was a SeniorFulbright Lecturer at theUniversidad Nacional deColombia, a visiting professor ofMathematics at the Universidadde Coimbra, Coimbra, Portugal,and a Visiting Mathematician atthe Mathematical Association ofAmerica. He received severalawards including the WexlerAward, Alumni AssociationService Award, and twoPresidential Awards forExcellence in Science, Mathematics,and Engineering Mentoring.

The passing of Dr. Bustoz has left avery large gap in the lives of severalpeople in Mathematics and around the University. Although he was neverone for drawing attention to himself,his friends and colleagues in theMathematics department can feel hisabsence daily, Dr. Bustoz hired many ofthe staff and faculty members that arestill here. I know that every time I hear someone walk in the stairwellwith Birkenstock’s on, I wait for someone to say “See you tomorrow,Kate!” but I haven’t heard that sincethe first week in July.

The future of the SUMS Institute isn’tclear, but the Math-Science HonorsProgram will continue without hesitation. Dr. Bustoz always dedicatedhis efforts to the increased preparationand enrollment of underrepresentedstudents in the math and sciences, thisdedication will not be diminished by his absence, but continued by the staff and family he worked with inMathematics. There will still be summers in Bateman filled with

anxious andrambunctioushigh school stu-dents, makingnoise just to beheard, whenthey start driv-ing you crazy,just rememberwhy the stu-dents are thereand thank Dr.Bustoz.

A scholarship fund has been established in honor of ProfessorJoaquin Bustoz. Donations to it maybe sent to:

students are essentially precluded at present from doublingbecause of the extra year it would take them to satisfy Liberal Arts College requirements, on top of our major requirements. Wehave devised some solutions to this hurdle that several depart-ments within FSoE find very attractive. Keep your ears open.Finally, we created a program in Cryptography that we hope willdraw the attention of a number of talented students. This program is analogous to the Actuarial program in that it is not a degree or concentration but rather a well-constructed set of recommended courses.

The Mathematics Club is alive and well with countably manyenthusiastic students. They have been holding regular meetings,with attendancetypically in the high twenties, including speakerssuch as the Director of Career Services, topics such as mathematical juggling, and activities like game night. Moreover,they first suggested the idea of an undergraduate research conference that led to funding by the Mathematics Association of America, among many other subsequent supporters, to hostone. On the dates of February 27-29, 2004, we will hold the FirstArizona Mathematics Undergraduate Conference -- yes, we arerunning AMUC!. The intention is to rotate the conference infuture years among UA and NAU and ASU. We expect some 80-100 participants from Arizona, New Mexico, and SouthernCalifornia for this grand inaugural event. The conference couldn'tcome at a better time for us as we begin to focus more on undergraduate research. The department has added the Jack H.Hawes Memorial Research Scholarship to our existing MathematicsUndergraduate Scholarship (see math.asu.edu/scholarship.htm)to encourage and reward our undergraduates in their researchendeavors. We have also invented new 1-credit courses(194/294/394/494) in Problem Solving to help students developtheir creative skills in this direction. Chris Heckman has done anoutstanding job with the more than 20 students who signed up for them. He has also taken over as official coach of our Putnamteam. Many of the team members have been using the newcourses to hone their skills. One of last years members, Andrew

Jennings, scored among the top 150 students (top 5%) nationwide(actually North America-wide) on the prestigious competition.Andrew was a former winner of our Undergraduate Scholarship, as was Collin Raymond, who has gone on to study at the LondonSchool of Economics through the support of his MarshallScholarship. Collin also made national headlines when he wasselected by USA Today as one of the top 20 students in America.

As our total class enrollment this fall (12,169 students) stayed inthe ballpark of last fall's number (12,016), enrollment in First YearMathematics courses jumped 4% from 7,263 to 7,565. We hiredthree new instructors who have helped share the load: We welcome Thistle Stacks, Roger Cooper, and John Pariseau and lookforward to their contributions to our program. For the first timethis fall we were able to redirect more than a handful of studentsinto two drop-back courses. We are eager to see if this experimentis a success; about 120 students took advantage of the opportunity. Placement of students into the appropriate entry levelmathematics course will be aided by the implementation of theUnified Placement Test. We have been using and collecting dataon the UPT for years. This spring will be the first time students willbe required to write the exam prior to enrolling in any FYM course.The placement test can be found on-line at fym.la.asu.edu/placement. The implementation of WeBWorK forhomework in FYM courses has been complemented in all CollegeAlgebra and Precalculus courses. Other courses on track to adoptthe WeBWorK system are Finite Mathematics and Brief Calculus.WeBWorK is currently being used in 115 sections of various mathematics and statistics courses which are taught by 70 differentfaculty of all ranks and which serve 4,665 students.

The 2003 Wexler Awards for OutstandingUndergraduate Teacher and OutstandingMathematics Undergraduate were presentedat the annual awards ceremony in May. TheOutstanding Undergraduate Teacher awardwas shared by Dr. Anmin Zhu and AssociateProfessor Hélène Barcelo. Dr. Zhu had quite anumber of strong recommendations from hiscalculus students some of whom had takenmore than one course from him. These nomi-nations stressed Dr. Zhu's enthusiasm, his carefor the student, and willingness to help out-side of class. Professor Barcelo, nominated forthe Wexler Award in several previous yearsincluding this one, has a strong record ofteaching and mentoring talented undergraduate mathematics majors. Sheserved as the faculty mentor for AndrewJennings, this year's co-winner of the WexlerMathematics Prize, for his undergraduateresearch project which was awarded first prizeinthis years Research Experiences forUndergraduates competition. Dr. Barcelo hadpreviously mentored another winner of thiscompetition. Congratulations to both Dr. Zhuand Professor Barcelo for their outstandingcontributions to undergraduate teaching!

The 2003 Wexler Award for OutstandingMathematics Undergraduate was shared bytwo students-Joshua Kantor and AndrewJennings, with several faculty nominatingboth. They are both truly remarkable undergraduate mathematics majors who have excelled in several of the department'sgraduate level mathematics courses. Each hasspecial strengths andis highly deserving of theaward. Congratulations to both Joshua Kantorand Andrew Jennings for receiving the WexlerAward and best wishes in their future mathematics education.

The department celebrated its fifth annual Mathematics Awareness Month inApril 2003, in coordination with the Joint Policy Board for Mathematics and colleges and universities across the country. The theme of this nationwide event was "Mathematics and Art".

The primary event was a public lecture by mathematician and sculptorHelaman Ferguson, and his wife Claire. Helaman Ferguson's sculptures are

located in institutions and collections world-wide; one of his mathematical algorithms hasbeen listed among the top ten in the twentiethcentury. Claire Ferguson has written extensivelyon Helaman's work and is also an artist.

The Fergusons' lecture, which was attended by a large and eclectic crowd, was titled``Mathematics in Stone and Bronze''. Using

slides and video, they showed how Helaman's creations go from initial conception through mathematical design and computer graphics to their finalform. They also discussed the innovative computer technology used to create tori and double tori, trefoil knots, wild and tame spheres, Moebius strips andKlein bottles out of solid stone.

A Math Department Open House and Barbecue preceded the Fergusons'lecture, and many people turned out --- including students from various areahigh schools --- to mingle with math professors and students on a beautiful April afternoon.

A special Math Awareness Colloquium was held later in the month, featuring a slide lecture and exhibit of anamorphic drawings and paintings by Kelly M.Houle. ``Anamorphosis'' refers to the projection or representation of an image on a planar or curved surface in which the original image can be viewed properly only from a certain point, or as reflected in a curved mirror. Ms. Houle's work was a fascinating introduction to this blend of mathematics and art.

The 2003 Math Awareness Month activities also included a panel discussion inwhich various mathematics and statistics faculty gave an overview of currentresearch in the department.

Philip LeonardPeople, not unlike life events, seldom tend to be monochromatic,yet to my eyes Phil has one dominant color. He is a good person.Over the roughly 25 years I have known him, he has been a person who quietly and without ostentation makes a positive contribution to whatever situation he finds himself. There seemsto be an aspect of the human genome (what perhaps is called "Mars" in western poetic parlance) which seeks to lash out and destroy. I certainly have some of this myself, as do most people I know. Phil's remarkable feature is that heseems to have been overlooked when this aspect ofhumanity got passed around. Phil has always beenthere to help; he seems to have never been thereto hinder. (Thank you Phil for this; I take thisopportunity to express deep gratitude on behalf of our community.) He persists in consistently, quietly and cheerfully making positive contributionsto our community. That's his main color. Now let'sget to the math!

Many of us got our Ph.D.s in areas distinct from combinatorics, butlater wound up doing a fair amount of work in a special branch of

combinatorics called combinatorial design theory. Both Phil and I have continued to do work in our "birth" area as well. Phil'sPh.D. was in algebraic number theory in the late 1960's. His earlywork involved third and fourth degree extensions of finite fields,and in the early 1970's he began collaboration with KennethWilliams in Ottawa. His research in small degree field extensionsover finite fields and the rationals persisted into the mid 1980'swith frequent collaboration with Williams which resulted in some20 or so joint research articles.

He became chair of the department in1985; a position he held for two years. Inthe early 1990’s his research activitiesbegan to be focused primarily in the areaof combinationial design. BruceAnderson introduced him to this topic inthe late 1970's. The two basic questionsof design theory are how to generate andclassify them. As in life, the color ofglasses you use to view mathematics canhave a great effect on what you do withit. Phil's glasses were colored "numbertheory and finite field extensions,” so

he used the arithmetic operations in finite fields as a tool for constructing new designs. It is clear to me that Phil has had a lot of fun working with these things over the years.

I hope that this does not leave you with the impression that Phil was only a researcher. Phil has made a great impact through histeaching. He won the Wexler award and an MAA teaching awardfor its southwest section. Phil has been very involved with helpingtrain teachers both by teaching MTE classes and other work (funded and otherwise) in concert with our Mathematics Educationgroup. When one thing ends and another begins, sometimes oneis given to musings about what things will have lasting impact. It seems highly likely Phil will have had a lasting impact in mathematics education through the influence he has had on the current teachers of our children.

It is impossible to completely represent any parent without saying something about his or her children. Mary and Phil have threechildren: Andrew, Stephanie and Maggie. They are all in their thirties and living back east. Stephanie has two small children (and Phil is trying to figure out how to get them on his bike without disturbing the calmness of their mother). I have not hadmuch contact with his family, but I have had some. As a result Isuspect that their color may not be much different from his.

The future? Phil may weave (in the literal sense of the word) and spend more time in New England, his place of roots, children andgrandchildren. Of course, such things are never certain. What iscertain is that we will miss him.

First of all, I would like to thank and congratulate Frank (JohnBurke, postdoc, MIT), Dieter (Rama Chidambaram, Asst. Prof.,U. of Michigan - Dearborn), Jack (Menassie Ephrem, CoastalCarolina U.), Sharon (Joe Hirman, Glaxo), Basil (Bong-Sik Kim,Zassenhaus Asst. Prof., Ohio State U.) , Rosie (Cristina Negoita,Asst. Prof. in research, ASU) and Carl (Youngsoo Ha, Postdoc,KAIST U., Korea) for each producing a Ph.D so far this year. Wehave several more lined up for December graduation. We mayhave another record year in Ph.D production (we had 10 lastyear). The record before last year is 7 Ph.Ds in 1995. And in the

period of 1987-1992, we producedonly 13 Ph.Ds. As the numbersshow, with the new streamlinedgraduate exam structure in placeand a newly established graduatementoring committee, our graduateprogram is greatly improved, andmuch more competitive and productive than our competitorssuch as UA, U. Utah and U. Florida.

This fall, we have 115 graduate students enrolled in our program(including MNS) and taking 1002

credit hours. 99 of them are in our program. Last fall, we had 83students enrolled in our graduate program taking a total of 831credit hours, an increase of over 20%.

We have 32 new students this fall 03. We made 28 TA offers, 24 accepted and enrolled in our graduate program, mostly inour Ph.D program. We had almost twice as many and clearlybetter applicants. Among them, 4 are minority students andmany from top schools in the US and the world. These studentsare very competitive and motivated. They recognize ASU and our faculty members’ strength. It is now a challenge for us tosee their strength. We must continue to strive to make their education experience a productive and rewarding one.

This semester is the first time in many years that we did not haveto cancel any graduate courses. After much work, we were ableto assign a TA grader to all our over booked qualifying classes.

In addition to passing the MIP program (Master’s in Passing)last year, we introduced this year (thanks to Marilyn and

others) a new MNS in Math Education. Last year, we administered for the first time three qualifying exams in oneyear. After much debate, we completed the restructuring of thequalifying exams this month.

We are in the early stage of a timely and time-consuming discussion on the introduction of an interdisciplinary appliedmath Ph.D program. We will start the discussion on designing a 5year BS/MS program soon.

Graduate program reportsBY YANG KUANG

This past year has seen a numberof exciting new developments. TheUndergraduate Committee hasbeen hard at work investigatingand implementing a number ofinnovations, and many newopportunities exist for our fastgrowing population of undergraduate majors.

Including students in all of ourfour degrees (Bachelor of Science,Bachelor of Arts, ComputationalMathematical Sciences, andMathematics Education), we havegrown from 351two years ago,to 382 last year(9% increase),to 419 this year(10% increase),189 of whom(45%) arefemale. We alsohave 80 stu-dents minoringin Mathematics.Some of thegrowth is due tothe 44 students obtaining a CMSdegree in only its second year ofexistence. Some credit is also dueto the recruiting efforts of ourCommittee in sending letters toparticular high-performing students in our core courses andin local high schools. The BarrettHonors College has done theirshare as well by enticing a numberof National Merit Scholars to studymathematics here. We now have31 Honors students pursuing ourdegrees. Moreover, with such aninflux of excellent students, ourmajors now boast an average GPAof 2.99, and nearly 30% of themhave a GPA above 3.5.Our committee is looking into

ways of attracting even moremajors by developing the BA insuch a way as to serve the needsof those students who may usetheir degree to pursue non-scientific careers. National statistics compiled by the NationalScience Foundation indicate thatover 90% of mathematics graduates go directly into theworkforce. Almost 80% are innon-science positions, and nearly40% are in management, sales, or administration. Thus we havebeen considering a number of

new courses that could beoffered for these students, courses thatwould give them necessary skills inapplying mathematicsin such environmentsand would be relevantas well for the 12%or so who decide topursue secondaryteaching. We havehad promising discus-

sions with the EconomicsDepartment, among others, alongthese lines, so look for some inno-vative offerings in the near future.The Mathematics Educationdegree is also under renovation, aswe look for ways to strengthen the mathematicalcontent knowledge of those wetrain to teach in the secondaryschools. Keep your eyes peeledfor improvements in that area aswell. Maybe the biggest newattraction to our degrees willcome from plans we are considering to facilitate doublemajors with students in the FultonSchool of Engineering. Such

New interdisciplinary programoff to a great startBY MICHELLE HOWE

In 2002 the Department of Mathematics joined forces with the School of Life Sciences, theWP Carey School of Business, and the Computer Science and Engineering Department, aswell as a variety of other faculty, to form the Computational Biosciences Program.Currently MS degrees are being offered but applications are in committee to make thisdegree ASU’s first Professional Science Master’s degree. Graduation requires 42 creditsincluding an internship and coursework in professional development as well as science and technology studies.

Due to the highly interactive nature of this program, enrollment has been capped at 40 students. In itsfirst year it reached 80% of its prescribed admissions and in the second year it was up to 95% of itsmaximum capacity. With the 2004 admission process on the horizon it is expected to be fully enrolled.

Current enrollment includes local, national, and international students of the highest quality.Prerequisites for admission are extensive and highly varied, requiring students to have a thoroughbackground in mathematics, biology, chemistry, and computers.

Service awards

The Mathematics Department mourns the tragic loss on August 13, 2003 of a great man.Beloved colleague, educational leader, and mathematician Professor Joaquin Bustoz passed awayfrom complications of injuries suffered in an automobile accident on July 6. Joaquin was a national leader of efforts to encourage young people from under-represented minorities to studyadvanced mathematics and science. In 1985 he founded the SUMS Institute (Strengthen

Understanding of Math and Science.) SUMS enables talentedstudents from inner city, rural and reservation high schools toenroll in rigorous ASU-credit courses in mathematics, physics,chemistry and biology. Former SUMS students have had a significant impact as math and science teachers in Arizonahigh schools. Others have forged successful careers in scientific and mathematical research. Joaquin also initiatedmany projects to improve mathematics instruction in Arizona’sreservation schools, obtaining funding from the NationalScience Foundation, the Eisenhower Foundation and the

Arizona Board of Regents. Beginning in 1999 he directed ASU’s NSF-funded MARC (MinorityAccess to Research Careers) Program. Joaquin’s achievements were recognized by an Award forthe SUMS Institute from President Bush in 2003, an Award for Excellence in Science, Mathematicsand Engineering Mentoring from President Clinton in 1996, and a National Education Award fromthe American Association for the Advancement of Science in 1990.

In addition to his efforts as mentor and administrator, Joaquin pursued a successful career as anactive member of the international mathematical research community. He published numerouspapers in the field of Classical Analysis. His 1975 article “Jacobi polynomial sums and univalentCeasaro means” in the Proceedings of the American Mathematical Society is widely cited in mathematics literature. Just before his death he was working with his student Luis Gordillo on a promising new version of classical summability theory called “q-summability.” In 2000 hehelped organize a major research conference, the NATO Advanced Study Institute on SpecialFunctions held at ASU.

Though Joaquin frequented lofty academic and administrative circles, he kept students as his firstpriority. He constantly reminded them that minorities could succeed at hard science and math. “I will work with you;” he told discouraged students. Former students testify that he: “changedmy life;” “showed me a new world;” “helped me to realize my dream.” He encouraged his students to return to their communities to make a contribution. By his own example, he showedthem how to live a life of service.

Joaquin spent most of his life as student and faculty member Arizona State University. Born inTempe on December 30, 1939, he attended Rural School, located on the northeast corner ofSouthern and Rural Road. At Tempe Union High School he was a member of the track teambefore graduating in 1957. As a youth he worked in local agricultural fields. After obtainingBachelor’s and Master’s degrees in mathematics from ASU in 1961 and 1963 respectively, heworked for the Navy in San Diego for a year before returning to ASU to complete his Ph.D. inmathematics in 1967. He taught at Ohio University, the University of Cincinnati, and theUniversidad Nacional de Columbia before returning to ASU in 1975. From 1982 to 1985 Joaquinserved as chair of the Department of Mathematics. In 1990 he received the Charles Wexler Award for Excellence in Teaching in the ASU Department of Mathematics.

Throughout his distinguished academic career, Joaquin remained a devoted family man. He relished working at home improvement projects with his children and took special delight in his grandchildren. He and his wife Maureen enjoyed entertaining friends and colleagues at backyard cookouts.

Joaquin will be greatly missed, especially by his wife Maureen, daughter Sarah, sons Matt andDavid, grandsons Kyle, Michael and Alex, sister Mary and brothers Manuel, Ramon, and Albert, as well has by his many friends and colleagues.

Roseann Revel was hiredin October, 1983 as theadministrative supportperson for theMathematics LearningCenter. At that time theLearning Center includeda Tutor Center for

students enrolled in Mathematics classes at Arizona State Universityas well as a Testing Center where the Mastery Exams for theCalculus classes were given. While workingwith the Learning Center, Roseann assisted withall aspects of the program, including budgetingand student payroll. She also helped in develop-ing advising schedules and was responsible forscheduling the undergraduate Mathematicscourses. Roseann has been called the “WelcomeWagon” of the Learning Center for her cheerfulness, joviality and willingness to work as a part of the team and the “Iron Hand” of theCenter for her willingness to take on the difficultassignments and take charge of any given situation when necessary.

She continued to work with the Learning Center until the Fallsemester of 1995 when the First Year Mathematics program came into existence. As a part of the FYM program the currentMathematics Testing Center was developed. Roseann wasinstrumental in the development of the Testing Center and, under

her watchful eye, it has continued to grow and improve until currently there are approximately 55,000 exams given in theTesting Center during an academic year.

Roseann received her AA degree from Mesa Community College in Management Supervision and was a member ofthe FYM team that was awarded the Governor’s Spirit of Excellence Award in 1998.

After twenty years of devoted service to theDepartment of Mathematics and Statistics, Roseannhas made the decision to make her health her toppriority and has been approved for disability statuswhich should continue until she is eligible for fullretirement. Upon her retirement she plans to moveto Bozeman, Montana to enjoy and take advantageof the refreshing clean air and beautiful mountainsthere.

The Institute for Strengtheningthe Understanding of Mathand Science has recently completed its 18th Math-Science Honors Program(MSHP). The late Dr. JoaquínBustoz started the program in1985 with 32 students fromPhoenix area high schools andcontinues, having served nearly 1,900 participants.

The Math-Science HonorsProgram in an intensive, residential program that givesunderrepresented students asuccessful university experienceand the ability to earn university mathematics creditwhile in high school.Participants in the program live on-campus, take a three or four credit mathematicscourse, and interact with faculty. This structured program includes traditional lectures, daily program sessions, frequent testing, andone-on-one tutoring. TheMath-Science Honors Programstresses hard work, disciplineand encourages students tocontinue their education pasthigh school. Applications for the MSHP 2004 will be available January 2004 on the web athttp://summs.la.asu.edu.For more information, please

“Let me check with someone who knows.” If I had a nickel andthen double it the next time and double it again the time afterthat, and so on, for each time I used that phrase with Bev in mind,

we all could retire. I cannot remem-ber a time when I asked Bev a ques-tion and she did not know theanswer or know who to go to for theanswer. Bev has been an exceptionalasset to First-Year Mathematics andthe Department. There is always aqueue of people waiting to enterBev’s office and it’s not just for thechocolate or an available chair for thereally good conversations but ratherto dip into Bev’s vast knowledge ofrules, history, protocol, spoken agree-

ments, and implicit assumptions that maintain the momentum ofour department. Moreover, her knowledge extends to every nookand cranny of what the PSA 211 office oversees, and we all areoften in her debt for what people perceive as the Undergrad Chairor Director’s competence. Bev has served her time and all of usvery well. Since 1996, the questions “Let me ask Bev”, “Is Bevaround”, “I need to find Bev to ask her a question”, “Is Bev here?I need some chocolate” have echoed through PSA 211.

One might be lead to believe Bev is clairvoyant. She has such agreat sense of anticipation and is fully in tune with what we're try-ing to accomplish throughout the year. On a day-to-day basis sheis always prepared, organized, and ready to tackle any job.However, Bev is fully human, very caring and keenly perceptive.Some of this probably comes from having raised several children,and some may come from having been a high school teacher, but Ithink most comes from just who she is. Her skills seem to have nobounds. She can handle sad, confused, demanding, and evenangry students with great compassion, professionalism, and attimes in the face of very poor behavior. Through it all there isalways time to share life's other issues, personal crises, gossip fromPSA 216 and of course some chocolate!

Sometimes, Bev just makes your day. Her efforts, skill, enthusiasm,knowledge and humor are what get us all through some of thosetough days. Always spoken with a smile “I’ll see you here tomor-row”. Fortunately for her and sad for us we won’t see Bev for toomany more tomorrows. Bev is trading in the 8-5 routine for an RVand a little palace in Yarnell, Arizona.

Bev, it has been great working with you. You truly have been aconsistent source of information and dependability. We will missyou. We all wish for you a fabulous retirement. And remember,keep your head down; a smooth swing will get you down the mid-dle of the fairway; two putts is a good thing and it must be noonsomewhere. Cheers.

The statisticians in the Department continue to contribute locally and nationally to avariety of statistical activities. Sharon Lohr received the newly established Gertrude M.Cox Award, funded by the RTI (Research Triangle Institute). RTI had noted that "distin-guished achievement awards" for statisticians usually honor individuals near the end oftheir careers.

The Gertrude M. Cox award acknowledges and encourages statisticians in mid-careerwho are "making significant contributions to statistical practice." The Award took place at the annual dinner of the Washington StatisticalSociety on June 10, 2003, where Sharon gave the invited speech. Sharon will also bechair of the Survey Research Methods Section of the American Statistical Association in2004 and was reappointed to the US Census Bureau Advisory Committee.

Kathy Prewitt returned from her sabbatical leave this fall after visiting the statisticsdepartments at Texas A&M University and University of California at Davis. She is chairof the committee to increase membership of the Western North American Region ofthe International Biometric Society. Jake Oleson is in his second year at ASU and is the

proud father of a new baby girl, Eva Shea Oleson, born inAugust. Jake has started a productive collaboration withfaculty in the School of Life Sciences. Dennis Young alsoreturned from his sabbatical this fall and has taken over asthe interim Director of the Committee on Statistics and theMS Statistics program.

The year saw the graduation of eight students in the MSStatistics program, and one in the MA Mathematics program

with emphasis in statistics. Joe Hirman completed his Ph.D. in August, 2003 under thedirection of Prof. Lohr. He took a position with Glaxo. There are currently twenty sta-tistics students in the MS Statistics program, two in theMA Mathematics program, and six in the Ph.D.Mathematics program. Started in August 2001, theCertificate in Statistics program has been extremely suc-cessful. Seventeen have obtained the Certificate sinceDecember 2002, and there are currently over 50 stu-dents enrolled in the Certificate program. In 2002 anemphasis in Industrial Statistics and Six SigmaMethodology was added to the Certificate program.

The thirteenth annual Statistics Week was held March26-27, 2003. The Statistics Fair had representativesattending from General Dynamics, America WestAirlines, Intel, NDCHealth, Motorola, and Honeywell.Our guest speakers this year were Karen Kafadar, Professor of Statistics at the Universityof Colorado-Denver, and Joe Cavanaugh, Associate Professor at the University ofMissouri-Columbia. Prof. Kafadar presented two talks: "Simulating Survival Probabilitiesof a Lander Mission on Mars," and "Statistical Analysis of Microarrays". Prof.Cavanaugh's talk was titled "Locally Self-Similar Processes and Their Wavelet Analysis."

A number of our statistics graduate students received awards this year. Liyun Gong received the Outstanding Student Award from the MS Statistics program in March, and Amylou Dueck received the TA Excellence in TeachingAward from the Department of Mathematics and Statistics. Amylou Dueck, PhilipBackus and Jenifer Bosches received Graduate College Awards for Tuition for the year.Congratulations to all of them for a job well done.
