Exploring human nature through the social web

Free public lecture discusses how online expression and communication is changing how we study human networks 

Philadelphia, PA—The web grows larger and more social every day, allowing ordinary people to express themselves more publicly and permanently than ever before through blogs and social media such as Facebook, Twitter, YouTube, Instagram, and Foursquare.

Sep Kamvar, LG Career Development Professor of Media Arts and Sciences and director of the Social Computing group at the MIT Media Lab, Massachusetts Institute of Technology, has had more than a decade of experience studying social technology that has emerged from this tremendous growth in public human communication and self-expression on the web.

In a free public lecture organized as part of the Annual Meeting of the Society for Industrial and Applied Mathematics (SIAM) in Chicago next week, Dr. Kamvar will discuss how this technological and accompanying cultural shift offers a great opportunity to study (and organize) people. “The Internet is bursting with people’s documented expression and communication, pictures and videos, all linked to freely available information about their location, time of day, weather, and more,” according to Kamvar.

Leslie Greengard to deliver The John von Neumann Lecture

The prize will be awarded at the SIAM Annual Meeting in Chicago

Philadelphia, PA—Leslie F. Greengard of the Simons Foundation and the Courant Institute of Mathematical Sciences at New York University has been awarded the 2014 John von Neumann Lecture prize.

The highest honor awarded by the Society for Industrial and Applied Mathematics (SIAM), the society’s flagship lecture—established in 1959 in honor of the Hungarian-American mathematician of the same name—is given to a mathematician, or a scientist in another field, who has made distinguished contributions to the field of applied mathematical sciences. Dr. Greengard will receive his award and present the associated prize lecture at the SIAM Annual Meeting to be held in Chicago next month. Read the rest of this entry »

Using math to analyze movement of cells, organisms, and disease

Philadelphia, PA—A few recent SIAM journal papers you should know about:

  Traveling waves model tumor invasion

Cell migration, which is involved in wound healing, cancer and tumor growth, and embryonic growth and development, has been a topic of interest to mathematicians and biologists for decades.

In a paper published recently in the SIAM Journal on Applied Dynamical Systems, authors Kristen Harley, Peter van Heijster, Robert Marangell, Graeme Pettet, and Martin Wechselberger study a model describing cell invasion through directional outgrowth or movement in the context of malignant tumors, in particular, melanoma or skin cancer. Tumor cells move up a gradient, based on the presence of a chemical or chemoattractant – this process is called haptotaxis. Receptors on the exterior of cell walls detect and allow passing of the chemoattractant. Based on the locations of these receptors, cells determine the most favorable migration direction.

Putting a number on opinion dynamics in a population

How math helps us analyze information distribution and assimilation 

Philadelphia, PA—Opinion formation in a large population is influenced by both endogenous factors, such as interaction with one’s peers—in-person and via social media—as well as exogenous factors, such as the media, of which mainstream media is one of the most influential factors. For example, according to a study conducted by the National Bureau of Economic Research in 2006, after the introduction and expansion of Fox News in the United States between 1996 and 2000, an estimated 3-28% of the audience was persuaded to vote Republican.

In a recent paper published in the SIAM Journal of Applied Dynamical Systems, authors Anahita Mirtabatabaei, Peng Jia, and Francesco Bullo use a mathematical model to study the process of information assimilation in a population resulting from such exogenous inputs. Read the rest of this entry »
