Thirteen applied mathematics majors , two pure mathematics majors, 听and a graduate student in 听MS Applied mathematics received their degrees at听the 2017 Spring Commencement. Among the undergraduate majors, three received teacher certification through 每日大赛网站鈥檚 STEM Teach Program. Congratulations to all. Not all graduates are seen in the picture shown below.

2017 O. L. Hughes Award 听 听Cyrus Koch, a BS STEMteach Pure听Mathematics student received the 2017 O.L. Hughes Award. The award is annually presented to an outstanding senior mathematics major based on their math achievement, GPA, and leadership. It is given in memory of late Professor O.L. Hughes, who was the chair of the Math Department at 每日大赛网站 from 1945 to 1967. Cyrus will graduate at the 2017 Spring Commencement. Cyrus has accepted a teaching position at North Garland High School in Garland, TX and will also be assistant coach for the school鈥檚 competitive math team. He plans to attend UT-Dallas to work on a MS in pure mathematics so that he can be involved in teaching and curriculum development for the school鈥檚 ultra fast-track math program.

2017 Dorothy Long Award听Andrea Weaver, a BS STEMteach Applied Mathematics student received the 2017 Dorothy Long Award, annually presented to an outstanding female junior. The award is given in honor of late Professor Dorothy Long, who was a mathematics faculty member and the Dean of Women at 每日大赛网站 in the 60鈥檚. Andrea received a Noyce Scholarship last year and presented 鈥淣onlinear Elliptical PDEs鈥� at the 2017 AMS/MAA Joint Mathematics Meeting. She attended the 2017 Oklahoma-Arkansas MAA Section Meeting and participated in the Math Jeopardy Contest. Also, Andrea is a recipient of a SURF grant and will begin research on 鈥淣onclassical Symmetries of Dispersion Equations,鈥� this summer with Dr. Danny Arrigo.

2017 Outstanding Graduate Student Award 听Katie Burden, an MA Mathematics Education student, received the 2017 Outstanding Graduate Student Award by the unanimous recommendation of the Department of Mathematics faculty. She has worked in collaboration with Dr. Jason Martin on her thesis 鈥淐ase Studies of Virtual Manipulative and Static Derivative Images鈥� and presented her research at the 2017 Oklahoma-Arkansas MAA Section Meeting. Beginning in fall 2017, Katie will teach at Little Rock Central High School.

A paper co-authored by Ms. Kaiyi Chen (a former masters’ student at 每日大赛网站 in applied mathematics), Dr. Ling He (Carmichael Professor Finance), and Dr. R. B. Lenin (Associate Professor of Mathematics) has been accepted for publication in the听Journal of Risk Finance.听听The paper is based on Chen’s thesis “Time Variation Paths of Risk Sensitivities of Bank Stocks in Past Two Decades.”听 Dr. Lenin was the principle thesis advisor.

This paper incorporates the Flexible Least Squares (FLS) approach with a free statistical computing and graphics software听R to estimate the three-factor model developed by He and Reichert in 2003 to trace time variation paths in risk sensitivities of bank stock returns during 1990-2014, one of the most serious financial crises period in the U.S. history. The results of the paper show that interest rate sensitivity of bank stock returns coincides with the听听 dramatic changes in the bond market. It was significantly positive before the 2006 subprime mortgage crisis, reduced to insignificant between 2006 and 2008, and turned into significantly negative between 2008 to 2014. Further, the results of this study found that bank stocks negatively respond to changes in housing prices between1990-1994 and after that the sensitivity turns into significantly positive. The significant shifts in risk sensitivities of banks stock returns coincide alterations in long-term interest rates and monetary policy, especially, the enormously stimulative monetary policy after the financial crisis in 2008.

Ms. Chen听is currently pursuing a master鈥檚 in statistics at the University of Missouri-Columbia where she plans to complete her 听Ph.D. in statistics.

On November 19,听听the Department听听hosted the听听second听annual calculus tournament. 听It was organized by Dr. Jeff Beyerl, Dr. Long Le, Rebecca Stage, and James Palmer, assisted by various other mathematics faculty members听and graduate teaching听assistants.听听听Seven teams of three students听each competed against each other to solve problems as quickly as possible. The problems ranged through a variety of material that students in calculus learn: fundamentals, limits, derivatives, integrals, applications, and a dash of history.

The winning team, calling itself听CAL, consisted of three students from Dr. Long Le鈥檚 calculus I course: Lindsey Hazeslip, Connor Wilson and Azaryah Wilson.

Several professional development workshops in computer science for high schools teachers were organized by 每日大赛网站 STEM Institute in collaboration with the Departments of Mathematics and Computer Science. They were held during June 9-11 and 16-18, 2015 from 12pm to 4pm on 每日大赛网站 campus. 听Dr. R.B. Lenin, Associate professor of Mathematics, was the lead instructor. Teachers from Alma, Little Rock, Mayflower, and Vilonia School Districts attended the workshop.

In this workshop, Dr. Lenin covered basic computer programming topics such as expressions, functions, simple control and looping statements using the user-friendly software known as 鈥楢lice鈥� during the first half of the workshop. In the second half, he introduced a high-level computer programming language known as 鈥楶ython鈥� to understand deeper concepts of computer programming. The participants were provided with computers, and 听each topic was covered by the instructor through extensive hands-on-experience in computer coding. On the last day of the PD, various topics of the Praxis test were covered by going 听over the sample questions of Praxis study companion – Computer Science 5651.

Details about the content of this PD can be obtained by contacting Dr. R.B. Lenin (rblenin@uca.edu). Details about future offerings can be obtained by contacting Dr. Uma Garimella (ugarimel@uca.edu).

Some comments from the participants are …

“It was such a pleasure to take your class. I hope I have the opportunity to study with you again.

I never would have thought that this would be a field that I would be so interested in, but it may be just the ticket for me. Thanks so much for making it interesting and fun.

I am excited about the opportunities that this could bring, and I don’t think that I would be thinking in those terms if we didn’t have a knowledgeable, patient, and passionate instructor. Thank you so much for that.听”

“This was the best PD I’ve ever attended and most engaging. You made the learning fun yet kept us challenged everyday. Thank you for all of your help and I look forward to seeing you in the future.”

“I really enjoyed being in your class and am looking into taking more courses.“
