Megan Mosier (Ecology 2017) presented the results of her senior research at the Joint Meeting of Ichthyologists and Herpetologists that was held July 12-16, 2017 in Austin, Texas. During her senior year at CBU, Megan studied salamanders from both the Tennessee and Arkansas sides of the Mississippi river. Megan’s research poster described the population variation in two species of Ambystomatid salamanders that were separated by the Mississippi river.
Spring break is over, but I’m not sure winter is. It is close to freezing this morning as I write this note. Last year we had such a mild winter that I had plenty of choices for a great springtime picture for the March 2012 newsletter, but this year I had a hard time finding a picture to take that would show spring. The forecast for Friday, the date for the newsletter to go out, is for a high around 70, and for me that qualifies as spring weather – yeah! While the Memphis winter this year was much colder than average, we had nothing like the snowy winter weather of the Midwest and Northeast.
College teaching is a lot like spring. Students come to college with a lot of potential hidden inside. It is the job of the professors to warm and water that potential so it can become a beautiful and fruitful reality. Like spring thunderstorms, college teaching has its trials and tribulations, for both students and faculty. But the beauty of the subject, like the sun, will eventually shine forth. To glimpse that light and to be able to share that light with others is an absolute pleasure for me as a professor.
I hope you enjoy this newsletter with its many items including the featured alum, the featured article on student groups, the nice thank you note, and the featured department: mathematics.

Dr. Robert Appling, Biology 2003, announced his engagement to Jenny Cappleman. Dr. Appling is graduated from Barry University (2008) and is currently a podiatrist at Southhaven Foot Clinic.
Jennifer Hiltonsmith, Natural Science 2011, is in the Graduate Biology program at the University of Southern Maine. She is currently studying the physiological effects of oil dispersant on blue mussels. With the oil spill in the Gulf of Mexico and the presence of the Portland-Montreal pipeline docking station in Maine, it is important to understand the effects that dispersants, which are used to clean up oil spills, may have on the wildlife environment. Blue mussels were selected as the test subject because they are very abundant in Maine and serve as a bioindicator. In addition to her thesis work she is also responsible for teaching Anatomy and Physiology labs. After completion of her master’s degree she plans on working for an environmental testing agency either with the government or in a private sector.
Brandon Maharrey, Biology 2012, was accepted to the Pediatric Oncology Education program at St. Jude Children’s Research Hospital for this summer.

The CBU Student Members of the American Chemical Society (SMACS) has been very active during the past year. The club received notification during fall 2012 that it will receive an Honorable Mention Award from the national office of the American Chemical Society for its 2011-2012 chapter activities. The CBU SMACS chapter was also notified during fall 2012 that it will receive a Green Chemistry Chapter Award from the American Chemistry Society’s Green Chemistry Institute. Formal presentation of the awards comes at the April 2013 National Meeting of the American Chemical Society to be held in New Orleans, Louisiana. Anyone with an interest in chemistry or biochemistry is encouraged to join the club; membership includes students from the School of Engineering and most majors in the School of Science. Yusef Akbik is the current President of the CBU SMACS chapter.
During the month of October, 2012, SMACS celebrated National Chemistry Week and Mole Day. 2012 marked the 75th Anniversary of the American Chemical Society’s Student Members clubs and the 25th Anniversary of National Chemistry Week. The week began with a surprise demonstration on Monday of Elephant Toothpaste in the lobby of Assisi Hall and continued with Diet Coke and Mentos on Tuesday outside Cooper-Wilson, The Flaming Gummi Bear on Wednesday, a Special Seminar of Chemical Demonstrations by Dr. Harmon Donathan on Thursday, and Foaming Pumpkins in the lobby of Cooper-Wilson on Friday. The club had its traditional Mole Day Dinner on October 23 at the Spaghetti Warehouse with student members and both current and Emeriti faculty in attendance. A good time was had by all!
The CBU SMACS Chapter participated in a variety of community service activities during the past year. The club is one of the sponsors of the Memphis-Shelby County Science and Engineering Fair. Members of the club serve important roles in the Fair handling registration, judging middle school science projects, helping with general set-up and program preparation, and serving as courtesy guides. The CBU chapter was also co-host for the Greater Shelby County local and National Examinations of the Chemistry Olympiad and the local High School Competitive Examination which were sponsored by the Memphis section of the American Chemical Society and were held during spring 2012.
The club participates in a wide range of additional service activities including chemical demonstrations for middle and high school students, participation in the Science Olympiad, participation in activities and demonstrations that promote environmental awareness, and assisting the Admissions Department with demonstration sessions during Science and Engineering Days.
The CBU chapter of SMACS participates in a number of activities with Tri-Beta, the Biology Honor Society. They co-host the annual ACS-Tri-Beta Christmas Party. Members of the CBU SMACS chapter participate in several Tri-Beta events, including Bowling for Hope North in Uganda and the Annual Volleyball Game for the Church Health Center. On March 14, 2013, Tri-Beta was the club’s special guest for a joint meeting featuring presentations by Kay Powell on Optometry School and Dominique Garcia-Robles (B.S. Chemistry, 2011) on service opportunities with SVOSH, Student Volunteers for Optometric Service to Humanity. Both Kay Powell and Dominique Garcia-Robles are students at the Southern College of Optometry School.
The Student Section of the Mathematical Association of America received the CREATIVE PROGRAM AWARD for its Chess Tournament at the Greek Awards 2012. They again hosted the event this past November. In addition to their usual activities: they created Fibonacci rectangles that resulted in the golden spiral seen through the Cooper-Wilson Science Center, students from the Geometry and History of Math class shared insights about the origins of zero and early (surprisingly accurate) computations of the Earth’s circumference; and teams challenged each other in a friendly game of Math Jeopardy. A new addition to the annual Pi Day celebration was the tattoos members showed off. Of course, that did not interfere with their eating pie. The group is planning a trip to Oak Ridge, Tennessee, where they will tour the Oak Ridge National Laboratories on March 25th. The theme of Math Awareness Month 2013 is the Mathematics of Sustainability. Sustainability is not only a hot national topic, but one that has inspired several initiatives on CBU’s campus in recent years. The MAA is planning activities to educate the campus about math’s role.
The CBU chapter of the Society of Physics Students (SPS) held a kite flying event at Shelby Farms in the spring, and had a paper airplane contest that included contestants from Rhodes College. SPS members also attended the Zone 10 SPS meeting at Henderson State University where Brent Holmes made a presentation. This fall it held a Science Jeopardy contest where teams from both CBU and Rhodes College competed. SPS members assisted with three of the Science Olympiad events this spring. SPS members also joined Rhodes College SPS members at a formal dance at the new Kroc Center this spring.
The Math Center is a very popular place and continues to set new records for usage. It is a place for free one-on-one tutoring in math. It is also a place to do your math homework by yourself or in a study group with others in the center. Here are profiles of two of the tutors. Profiles of some of the other math tutors can be found in previous issues of this newsletter.
Rebekah Herrman is a junior Math and Physics double major who graduated from St. Benedict at Auburndale High School. She has been a tutor in the Math Center since her freshman year. She has helped many students and has been a real asset to the tutoring program. Rebekah is the president of the CBU Student Chapter of the Mathematical Association of America (MAA) and is on the Honors Program Board of Directors. She also is a resident assistant in Rozier Hall and is involved in campus ministry and the Society of Physics Students (SPS).
Alex Grover, a senior Mechanical Engineering major, has been working in the Math Center since the beginning of the semester. Though his involvement in math tutoring has been brief, he is no stranger to the program. Over his last four years he has taken many math courses, both fundamental and higher level. He has enjoyed passing on some of what he has learned to other students. Aside from tutoring, he has been active in engineering projects on campus as well as internships.
My name is Christina Brown Tran. I graduated from CBU in 2006 with a major in biology and minors in chemistry and behavioral science. I started CBU knowing that I wanted to go medical school to become a surgeon. However, life had different plans. I did not get accepted to medical school for the 2006-2007 school year and I was devastated. With the support of some amazing teachers and friends, I found my “plan B.” Little could I have known at the time, my new path would turn out to far surpass my original plan.
I got a job working as a clinic assistant at the Church Health Center, a not-for-profit clinic that provides healthcare for the working uninsured. Through that opportunity, I realized importance of service to the poor. I also went to graduate school and received a Master’s of Science in Epidemiology and worked on a childhood obesity study and a brain development study.
I started medical school in August of 2010 and it was terrible. It has been the hardest thing I have ever done- hours upon hours of studying, missing friends and family, and special events. I spent the first two years of medical school wondering if I had made the biggest mistake of my life. But, thankfully, third year changed everything. During the third and fourth years of medical school, students are let loose in clinics and hospitals. Third year has reminded me of why I have been studying so hard- to take care of my patients.
Through all the tears and laughter of the last eleven years, CBU has played a huge role in my life. I met some of my best friends in Dr. Ogilvie’s freshman biology. I met my husband in the Spain Auditorium. I met some of my best advocates in their shoebox offices in the old Science building. I was incredibly blessed to have had the opportunity to attend CBU.

Subject: RE: statistics help
I have to tell you, I do not ask for help very often. I could probably count on one hand how many times that I have. I just want to let you know that the help you gave me may not have seemed like a huge deal to you but it made all of the difference in the world to me. I messed with those graphs every day in January and could not figure out what I was doing wrong. I talked to you Thursday morning and had all of my graphs revised by Friday afternoon! They are now exactly as Dr. Simco requested. I cannot thank you enough James.
The Mathematics Department serves essentially every CBU student and is probably the biggest service department at CBU. It provides courses for Arts majors, courses for Business majors and many courses for Engineering and Science majors. It offers a Bachelor of Arts degree in mathematics, a Bachelor of Science degree in mathematics and a dual degree in Math and Computer Science. There are options in the math degree in bioinformatics with a minor in biology or chemistry, and an option in forensics with a minor in biology. Most people recognize that you can teach with a math degree, and we do have a program for teacher licensure in Math. There are lots of other career options with a Math degree.
Math for some students is a fascinating and wonderful subject. For others it is something initially feared and dreaded. This wide range in attitudes and backgrounds in mathematics provides quite a challenge for the department. To handle this challenge, the departmental faculty have tried many different teaching techniques and use a wide array of tools.
It all starts with trying to place students at the appropriate level. The initial placement is based on ACT scores, but the department offers placement tests for those who think their ACT results do not really indicate their level of skill and knowledge.
The Mathematics Department continues to explore ways to increase student success. To meet the needs of students who require a review of algebra before attempting other mathematics courses, the department has recently created three new ALG courses, ALG 110, ALG 115 and ALG 120. The department offers these in the fall in the day program and in the professional program in the evening. They are designed to prepare the student for Finite Math, MATH 105. The department hired Mrs. Sandra Davis a couple years ago to help with the new ALG courses. The Math 103 course was designed as a prerequisite for those that will take Precalculus and Calculus. Both the ALG courses and the MATH 103 course use computer tutorials to supplement instruction by the professor. These tutorials allow students to spend more time concentrating on individual weaknesses.
In the fall semester, the department incorporated the use of online interactive homework in its precalculus course, Math 117. The students in the course completed assessments in precalculus to help them learn and to prepare them for calculus. These assessments were developed at Pierce College in the state of Washington, are free and available at www.myopenmath.com. Dr. Andrew Diener, Assistant Professor of Mathematics, and Dr. Arthur Yanushka, Professor of Mathematics, modified them for use in CBU’s course.
During the summer of 2012 Dr. Arthur Yanushka developed similar online assessments for Math 132 Calculus II, Math 232 Calculus III and Math 309 Probability. His students used these assessments during the fall and spring semesters.
This is the eighth year of a special course, Math 129, that was designed to improve success for engineering students. The math department calls it MIFE (Mathematics Immersion for Freshman Engineers). Dr. Pascal Bedrossian and Professor Cathy Grilli have been team-teaching Math 129 in the fall semester. In it, students meet for nine contact hours each week and cover the topics of Pre-calculus and Calculus I. The students who succeed in the course are pleasantly surprised in Calculus II when the lectures are less than an hour!
Br. Joel Baumeyer continues to serve as Director of the Math Center which offers free assistance in mathematics, physics and computer science to CBU students. Tutors are typically CBU students majoring in mathematics, engineering or the sciences. These tutors take pride in offering their services to their fellow students. Since moving into the new Math Center room in Cooper-Wilson, student visits have increased from about 1,000 per semester to above 3,700 per semester.
In the upper level courses, the department uses the MAPLE programs to help make the material as visual as possible. Br. Walter Schreiner, Associate Professor of Mathematics, spent many hours of the past couple summers revising and updating MAPLE worksheets and aligning them with our new calculus text. Dr. Leigh Becker, Professor of Mathematics, continues to use MAPLE in his manuscript Ordinary Differential Equations: Concepts, Methods, and Models. CBU uses this manuscript as the text for MATH 231 Differential Equations. Dr. Holmes Peacher-Ryan, Associate Professor of Mathematics, is doing research on the robustness of maximum likelihood factor analysis using five-valued Likert data. As an example of five-valued Likert data, consider the sort of questionnaire we have all seen in which we answer “1″ for “strongly agree”, “2″ for “agree”, “3″ “neutral” or “don’t know”, “4″ for “disagree”, and “5″ for “strongly disagree”. Maximum likelihood factor analysis is a statistical technique which finds underlying factors or “causes” of the pattern of responses to a group of questions.
This year four seniors will graduate this year with B.A. or B.S. degrees in mathematics. Besides the usual array of mathematics courses, math majors must also take two semesters of seminar (Math 481-482) in their senior year. A fifth student is also taking seminar but will graduate in 2014. Raymond Bedrossian’s project is a study of the equations required to track an object, specifically its orientation, using a gyroscope and accelerometer. The main focus is on how to quickly compute the current orientation of the object on a cheap, low powered computer by using linear algebra concepts to create an accurate approximation algorithm as opposed to using exact equations, which can take too long to compute. Brent Holmes’s project is on chromatic numbers of infinite hypergraphs on the real plane. Brent uses hexagon tilings to prove restrictions on the chromatic numbers.
Aaron Lewis’s project is on the finite element method which includes a myriad of analysis techniques, e.g., direct stiffness method, which help solve for internal forces, stresses, and strains in structural members and systems. This is done by considering elemental adjacencies, external and internal loads, and boundary conditions. Michelle McEachron’s project analyzes non-periodic tilings of the plane. In particular she looks at how Penrose tiles force a non-periodic tiling when certain guidelines are followed. Megan Wilson’s project is on using neural networks to estimate breast cancer risks. By using neural networks, a model that uses probability distributions, resampling techniques such as bootstrap can be made to approximate the probability of malignancy directly. Raymond Bedrossian is a double major in Electrical Engineering and Computer Science and Mathematics. Brent Holmes is a double major in Mathematics and Physics. Aaron Lewis is a double major in Civil Engineering and Mathematics.
Dr. Leigh C. Becker, Professor of Mathematics, submitted a paper for review and publication during spring break entitled Resolvents and Solutions of Singular Volterra Integral Equations with Separable Kernels. This paper continues his recent efforts to develop techniques for finding closed-form solutions of certain types of integral equations. The following papers dealing with similar topics were published last year: Resolvents for weakly singular kernels and fractional differential equations, Nonlinear Analysis: Theory, Methods & Applications, 75, Issue 13 (Sept. 2012), pp. 4839-4861, and Singular integral equations, Liapunov functionals, and resolvents, Nonlinear Analysis: Theory, Methods & Applications, 75, Issue 7 (May 2012), pp. 3277-3291 (coauthored with T. A. Burton and I. K. Purnaras).
The Math Department also provides service to the university and community through the Student Section of the Mathematical Association of America which is part of our featured article on Student Groups earlier in this newsletter. In addition, Dr. Andrew Diener, Assistant Professor of Mathematics, is the CBU site director for the West Tennessee section of the Science Olympiad (see News of the Moment section earlier in this newsletter). The Math Department also provides support so that CBU can be a test site for the Tennessee Mathematics Teachers Association high school tests in the spring.
