Epidemiology: Role of dynamic individual decisions during ongoing epidemic outbreaks

The lecture begins with a historical review of epidemic models and the concept of tipping point. We then revisit phenomenologically inspired modeling frameworks that account for the impact that single disease outbreaks have on the decisions that individuals make in response to real or perceived risk of infection. Finally, a behavioral framework where individual decisions are modeled as a function of tradeoffs made in response to self-assessed costs tied to present or future risks of infection, including those resulting from potential loss of benefits due to risk aversion decisions is introduced and implemented on a simplified population-level epidemic model. The impact of these decisions is illustrated in the context of a single influenza outbreak.

How Mathematics Is Making Hollywood Movies Better

What’s your favorite movie? Star Wars? Avatar? The Avengers? Frozen? What do these and all the highest earning Hollywood movies since 2000 have in common? Mathematics! You probably didn’t think about it while watching these movies, but math was used to help make them. In this presentation, we will discuss how math is being used to create better and more realistic movies. Along the way we will discuss some specific movies and the mathematics behind them. We will include examples from Disney’s 2013 movie Frozen (how to use math to create realistic looking snow) to Pixar’s 2004 movie The Incredibles (how to use math to make an animated character move faster). Come and join us and get a better appreciation of mathematics and movies.

Call for Student and Faculty Papers

As usual, we hope for a wide variety of talks from our own members. If you have something interesting to say about mathematics or teaching, contribute a talk and share with the rest of the section. Students (both undergraduates and graduates) are encouraged to participate.

Note: We are hoping to hold a special student session and we need your help! Please encourage your students to submit an abstract for a talk about their favorite problem, theorem, or mathematician. We do not expect work to be original to the student, but the presentation should be. We are especially interested in talks focused mathematicians who are minorities and their math.

Proposals for talks are due by September 21. Please use the electronic submission form, if at all possible. (Logging in first will make it easier, so you are encouraged to do so.) If you are unable to use the submission site, please send the following information to Angela Kohlhaas at Loras College - angela.kohlhaas@loras.edu:

Thank you for considering preregistering for the upcoming meeting. This will save you time at the meeting, make it easier for our secretary at the meeting, and increase the efficiency in gathering the data that the MAA headquarters asks of us for each meeting (including gender, whether you are a presenter, and student/faculty/other status). When you come to the registration table at the meeting, indicate that you have already preregistered. Your name will be looked up from the list gathered from this registration tool and you will only need to pay the registration fee ($15) to complete the process. If you want to prepay using PayPal, this is done in the paragraph below. Preregistration takes place here. Note that you can use this page whether you are currently in our database or not (see below), but the process will be much easier if you already are.

The registration fee for those who have to pay (people who aren't students or invited speakers) is $15 and can be paid below. Note that this is a second step to the registration process.

IA section database

We are trying to maintain an up-to-date database of all section members to provide better communication, save expenses on mailings, and help with the registration and proposal process. If you have not already updated your information, you may do so by using the log in page here. The credentials that you need here are your email and your password. If you forgot your password, you can always have it sent to by using the "I forgot my password" link on the log in page (log in). This assumes that you are in the system. If you are not sure if you are or not, check here. If you are not in the system, use the Contact menu there to send a message to request to be added.
