The ridesharing economy is experiencing rapid growth and progress. Companies such as Uber and Lyft are continuing to grow while providing their platform as an organizing medium for ridesharing, increasing consumer utility as well as employing thousands in part-time positions.
However, many challenges remain in the modeling of and understanding of rides-haring services, many of which are not currently under investigation by the academic community. In this paper an agent-based model is developed to simulate a ridesharing service in the Washington D.C. metropolitan region. The model forms the basis for future experiments to determine the levels of utility to both riders and [...]
So the analysis of negative ties in social networks is a growing field of study in academic circles and by social network theorists as well as agent-based modelers. Negative ties are basically a network relationship based on some negative or dislike or opposition attitude toward another actor in a network environment. Negative tie analysis is not clearly understood in the literature, and treatment of negative ties both structurally and mathematically is an area of early development in social network methodology and analysis.
But the space is going to become more important. Understanding group behavior under negative tie conditions is an increasingly important [...]

In the 1970s a prominent social science researcher by the name of Thomas Schelling surprised his colleagues (and a bunch of other people) by building a computational/mathematical model that showed that only a slight racial, or color-based preference in a buyer’s geographic decision on a home purchase can create very segregated societies. In other words, that communities in cities and rural areas which tend to be heavily dominated by specific group or demographic can result, even when people living in those communities are not necessarily super racist or bigoted.
Before you go hang a huge sign outside your door that celebrates the end of racism or something, [...]
