Representing and Analyzing the Dynamics of an Agent-Based Adaptive Social Network Model with Partial Integro-Differential Equations
Get PDFWe formulated and analyzed a set of partial integro-differential equations that capture the dynamics of our adaptive network model of social fragmentation involving behavioral diversity of agents. Previous results showed that, if the agents’ cultural tolerance levels were diversified, the social network could remain connected while maintaining cultural diversity. Here we converted the original agent-based model into a continuous equation-based one so we can gain more theoretical insight into the model dynamics. We restricted the node states to 1-D continuous values and assumed the network size was very large. As a result, we represented the whole system as a set of partial integro-differential equations about two continuous functions: population density and connection density. These functions are defined over both the state and the cultural tolerance of nodes. We conducted numerical integration of the developed equations using a custom-made integrator implemented in Julia. The results obtained were consistent with the simulations of the original agent-based adaptive social network model we previously reported, confirming the robustness of the original finding. Specifically, when the variance of cultural tolerance d is large enough, the population with low d maintains the original clusters of cultures/opinions, while the one with high d tends to come to the center and connect culturally distant groups. Parameter dependence of the model behavior was also revealed through systematic numerical experiments

Modeling Empirical Stock Market Behavior Using a Hybrid Agent-Based Dynamical Systems Model
Get PDFWe describe the development and calibration of a hybrid agent-based dynamical systems model of the stock market that is capable of reproducing empirical market behavior. The model consists of two types of trader agents, fundamentalists and noise traders, as well as an opinion dynamic for the latter (optimistic vs. pessimistic). The trader agents switch types stochastically over time based on simple behavioral rules. A system of ordinary differential equations is used to model the stock price as a function of the states of the trader agents. We show that the model can reproduce key stylized facts (e.g., volatility clustering and fat tails) while providing a behavioral interpretation of how the stock market itself can cause periods of high volatility and large price movements, even when the economic value of the stock grows at a constant rate
Soaring into the Future of Chat Reference: Assessing for Quality in Cooperative Chat Reference
Get PDFOnline reference allows for libraries to join cooperatives to provide chat reference when local librarians are not available, far extending the hours assistance is available to patrons. As the future brings more cross institutional collaboration, how do we know that cooperative chat is effective for our patrons? Librarians at one institution worked to develop a rubric to assess chat transcripts for the quality of services provided. Over one academic term, these librarians assessed chat transcripts answered by academic librarians from other libraries. This poster will share the rubric used to assess transcripts, research methods, and initial findings from collected data
Torus links (4,2) Olivewood. Figure 4
No full textA 4,2 torus link carved from Olivewood. completed four new wooden torus knot sculptures, two from Purpleheart wood and two from Olivewood. One of the Purpleheart pieces came from a 2 x6 x6 block, and all the others were from 2 x4 x4 blocks. I made two (3,5) torus knots, one from the larger Purpleheart block and one from an Olivewood block. The other two smaller blocks were made into torus links, that is, two (2,1) torus knots linked, which happens when you make a (4,2) torus ``knot .https://orb.binghamton.edu/mathematical_sculptures/1622/thumbnail.jp
