Location: Hallam Auditorium, Room 206, Claxton Building, 1122 Volunteer Blvd.
Speaker: Yingkui Li, Geography, UTK
Topic: Mapping topography and surface processes using unmanned aircraft system and structure from motion
Abstract: The recent development in unmanned aircraft systems (UAS) and structure from motion (SFM) provides a rapid, efficient, and low-cost means to map detailed topography and quantify earth surface processes in a much finer (up to cm-level) resolution. This presentation introduces the recent teaching and research activities associated with UAS and SFM in the Department of Geography, including the accuracy assessment of UAS-mapped topography based on the comparison with the topography generated using the terrestrial laser scanner, and the pros and cons of various software packages and web services in mapping various terrain features (such as ground surface, vegetation, and buildings), and the potential of using UAS and SFM to map the extent and extract the 3-D characteristics of Kudzu.

Topic: Modeling the evolutionary origins and dynamics of social complexity
Abstract: It is now well recognized that understanding modern human behavior, psychology, culture, and certain economic and political processes is hardly possible without also considering factors and processes that were shaping our recent evolution. Deciphering the problems of human origins and subsequent social and cultural evolution requires a concerted effort of researchers from a diverse set of disciplines including biology, anthropology, psychology, economics, and history as well as mathematics and computational science. If we, as scientists, are successful in this endeavor, the societal impact will be enormous. I will illustrate some of my recent modeling work in this area. I will consider the collective action problem in heterogeneous groups, effects of identify fusion on self-sacrifice, the evolution of social norm internalization, and the joint dynamics of power inequality and cooperation.

Topic: Exploring nanobiological structures with 3D nanotomography, 4D printing via self-assembly, and graph theory
Abstract: We have been doing 3D X-Ray nanotomography of radiolarian tests and studying them geometrically and topologically. Also, we have been 4D printing via self-assembly icosahedral viral capsid models. I will bring along a variety of models that we have built to illustrate our work. Click here for more information.

Time/Date: 12:15 p.m. Friday, Sep 14, 2018
Location: Hallam Auditorium, Room 206, Claxton Building, 1122 Volunteer Blvd.
Speaker: Michael Buban, Air Resources Laboratory, Atmospheric Turbulence & Diffusion Division, NOAA
Topic: NOAA UAS Research and Technology Program: Moving research UAS platforms into operations
Abstract: NOAA's Atmospheric Turbulence and Diffusion Division (NOAA/ATDD) has been testing small unmanned aircraft system (sUAS) platforms and instrumentation to make high-resolution measurements of thermodynamic properties of the Earth's lower boundary layer and surface for the past four years. The use of sUAS for atmospheric research provides unprecedented access to a heretofore undersampled region of the lower boundary layer. Flights on a routine basis over a variety of land-surface types in various seasons will allow improvements in weather forecast models. This presentation will cover NOAA/ATDD's most recent developments in evaluating meteorological sensors for suitability for use on its small UAS, calibrating the sensors to NIST-traceable standards, validating the sensors performance against other measurement systems, and assessing the value of small UAS airborne systems for monitoring weather conditions on a routine basis.

Topic: Tragedy of Open Ecosystems
Abstract: This presentation investigates the role played by cooperation for the sustainable harvesting of an ecosystem. To achieve this, a bio-economic model based on multi-species dynamics with interspecific relationships and multi-agent catches is considered. A comparison between the non-cooperative and cooperative optimal strategies is carried out. Revisiting the Tragedy of Open Access and over-exploitation issues, it is first proved analytically how harvesting pressure is larger in the non-cooperative case for every species. Then it is examined to what extent gains from cooperation can also be derived for the state of the ecosystem. It turns out that cooperation clearly promotes the conservation of every species when the number of agents is high. When the number of agents remains limited, results are more complicated, especially if a species-by-species viewpoint is adopted. However, we identify two metrics involving the state of every species and accounting for their ecological interactions which exhibit gains from cooperation at the ecosystem scale in the general case. Numerical examples illustrate the mathematical findings. Click here for more information. Seminar flyer (pdf).

Topic: Cultural prerequisites for democracy and economic development
Abstract: The World Values Survey (WVS) quantifies the cultural values of 109 nations that represent 95% of the world's population on all six inhabited continents. Using unsupervised statistical methods, we present two orthogonal cultural components (Openness and Secular-Rationality) that underlie these data. Using a multilevel time series model, we show that Openness and Secular-Rationality must generally be infused into the population of a country before it becomes economically developed. Moreover, these cultural values not only also predict future levels of democracy, but also predict future democratic stability. Click here for more information. Seminar flyer (pdf).

Topic: Songbird social psychology: Flock complexity affects Carolina chickadee behavior
Abstract: We have known for decades that animal behavior is influenced by the genetic and developmental backgrounds of individuals. In human behavior, it is also clear that the immediate social context of an individual powerfully influences her or his behavior. It is becoming increasingly clear that social context also plays an important role in non-human animal behavior. This presentation will outline a few of the experiments we have conducted recently on the vocal and problem-solving behavior of Carolina chickadees, a small songbird common to the southeastern United States. We have found that chickadee flock size and composition influence the complexity and use of calls by individuals, and also their ability to solve novel foraging problems. Our work provides support to the hypothesis that social complexity drives communicative complexity and may drive social intelligence. Click here for more information. Seminar flyer (pdf).

Topic: Climate change and tipping points for seabird colonies in the Pacific Northwest
Abstract: Changes in sea surface temperatures in the Pacific Northwest are associated with changes in reproductive and feeding tactics in colonial seabirds. Warm years in the El Niño–Southern Oscillation are associated with short-term "lifeboat" tactics such as egg cannibalism that are not sustainable over the long term. Mathematical models suggest that prolonged rises in sea surface temperature can create tipping points that allow colony collapse. Click here for more information. Seminar flyer (pdf).
