Mathematical Philosopher at Brown Bag Lunch

Aydin Mohseni, a mathematical philosopher at the University of California, Irvine, will be the featured speaker at the weekly CMCI Brown Bag Lunch on Monday, September 24.

Talk title: “On the Emergence of Minority Disadvantage: Testing the Cultural Red King Hypothesis.”

Abstract: The cultural red king effect predicts that differentials in group size may lead to inequitable outcomes for minority groups even in the absence of explicit or implicit bias. We test this prediction in an experimental context where subjects divided into groups engage in repeated play of a simplified Nash demand game. We run 14 trials involving a total of 112 participants. The results of the experiments are significant and suggestive: individuals in minority groups do indeed end up making low demands more frequently than those in majority groups, and so receive lower payoffs.

Undergraduate Research at the U of I

CMCI is pleased to contribute to the research efforts at the University of Idaho and provide opportunities for students to gain hands-on field experience. Why is it important? President Chuck Staben recently asked David Pfeiffer, Director of the Office of Undergraduate Research, the same question and shared his answer in the Friday Letter –

President Chuck Staben: Why is undergraduate research, scholarship and creative activity so important? What do such opportunities mean for students?
David Pfeiffer: Research projects, scholarly activities and creative activities are fundamentally different from class work and the experience of doing them can engage students in wholly different ways. They demand a kind of tenacity and creativity that often isn’t fully realized in traditional classes and labs. Collectively, they are recognized as among a handful of high-impact educational practices that help foster critical thinking skills, innovation and independence in students. As such, these experiences help better prepare students for success during their degrees and beyond, regardless of their career path. Employers are not in the dark on this, and they are increasingly looking for evidence of these types of experiences on students’ resumés.

Modeling Gut Microbial Dynamics

Join us for the next joint-hosted IBEST/CMCI seminar on Thursday, September 13, 12:30 p.m. in EP 122. Sean Gibbons from the Washington Research Foundation will present, “How do we model gut microbial dynamics?“

Abstract:

Dynamics reveal crucial information about how a system functions. However, it is not yet known what the relevant timescales or models are for understanding microbial dynamics in the gut. For example, gut microbial population dynamics may be largely internal, and the stool samples we obtain likely represent the end-point of these internal dynamics. In this talk, I describe a statistical approach for disentangling different components of dynamics within the human gut microbiome: autoregressive and non-autoregressive. Autoregressive dynamics involve recovery from large deviations in community structure. These recovery processes appear to involve the blooming of facultative anaerobes and aerotolerant taxa, likely due to transient shifts in redox potential, followed by re-establishment of obligate anaerobes. Non-autoregressive dynamics carry a strong phylogenetic signal, wherein highly related taxa fluctuate coherently. These non-autoregressive dynamics may be driven by external, non-autoregressive variables like diet. Most of the community variance is driven by day-to-day fluctuations in the environment, with occasional autoregressive dynamics as the system recovers from larger shocks. Despite frequently observed disruptions to the gut ecosystem, there exists a strong returning force that continually pushes the gut microbiome back towards its steady-state configuration.
