Large-Scale Structure in Networks (Santa Fe Institute)


An interesting talk from the Santa Fe Institute on how understanding large-scale networks (the speaker, Mark Newman, works primarily with social networks) can help us understand complex systems.

What the large scale structure of networks can tell us about many kinds of complex systems

June 5, 2014 | Santa Fe Institute


Networks are useful as compact mathematical representations of all sorts of systems. SFI External Professor Mark Newman asks what the large-scale mathematical structures of networks can tell us.

Mathematical measures of network properties such as degree (a measure of average connectivity) and transitivity (a measure of second-order connectivity) are simple, often-used ways of understanding network structure at a local level.

Newman is interested in larger-scale structures of networks with thousands or millions of nodes. He reviews statistical techniques that offer such large-scale insights, as well as potential predictive capabilities.

His presentation took place during SFI's 2014 Science Board Symposium in Santa Fe.

A New America: How Millennials Are Sparking Change


This 2+ hour discussion on the Millennials is brought to you by Microsoft, The Atlantic, National Journal, and FORA.tv. It was held at the University of Texas, Austin, on March 25, 2014, featuring Margo Dover, Jae Kim, Trey Martinez Fischer, Bob Metcalfe, Jason Seats, Michele Skelding, and Wendy Spencer (biographies are provided below).
Summary

Millennials are on track to be the most educated, the most connected, and the most wired generation, with a bent for entrepreneurship and service. Evidence shows that Millennials may represent the tipping point generation in America, whose preferences and priorities are setting the direction for public and private life over the decades ahead. They are, by far, the most diverse generation in American history, with non-whites comprising about 40 percent. Austin, Texas has become a hub for Millennials and millennial entrepreneurs; the city's open and collaborative business climate has turned it into a unique entrepreneurship incubator.

Join National Journal and The Atlantic for the second in a series of town hall events as we go to the heart of Austin to examine the opportunities, inclinations and impact of this giant influential generation. This exciting event will focus on how Millennials are using entrepreneurship to build a pathway to success, and will feature insights from Millennials, government officials, educators, entrepreneurs, and more.

Douglas Rushkoff - Present Shock

In this video posted at the IEET (Institute for Ethics and Emerging Technologies), Douglas Rushkoff talks about his most recent book, Present Shock: When Everything Happens Now (due out in March).
Back in the 1970s, futurism was all the rage. But looking forward is becoming a thing of the past. According to Douglas Rushkoff, “presentism” is the new ethos of a society that’s always on, in real time, updating live. Guided by neither history nor long term goals, we navigate a sea of media that blend the past and future into a mash-up of instantaneous experience. 
Rushkoff shows how this trend is both disorienting and exhilarating. Without linear narrative we get both the humiliations of reality TV and the associative brilliance of The Simpsons. With no time for long term investing, we invent dangerously compressed derivatives yet also revive sustainable local businesses. In politics, presentism drives both the Tea Party and the Occupy movement. 
In many ways, this was the goal of digital technology—outsourcing our memory was supposed to free us up to focus on the present. But we are in danger of squandering this cognitive surplus on trivia. Rushkoff shows how we can instead ground ourselves in the reality of the present tense.
Here is the talk.

Douglas Rushkoff has been an authority on the intersection of technology and culture since before the word “google” was anything more than baby talk. He predicted the coming centrality of the Internet (CYBERIA, 1992 – a book initially canceled by a publisher who feared the net would be over by the time it came out); he coined the terms “viral media” (MEDIA VIRUS, 1994) and “social currency” (Upside Magazine, 1996); he forecasted the collapse of the dotcom bubble (SXSW, 1997) and the most recent recession in a 2004 column that later became his book, LIFE INC; he even inspired today’s code literacy movement (PROGRAM OR BE PROGRAMMED, 2010). He is the author of a total of twelve bestsellers (translated to over thirty languages), the host of three award-winning documentaries, an award-winning educator and frequent media commentator.

EDGE: Thinking in Network Terms - A Conversation with Albert-lászló Barabási

From Edge, this is an interesting talk by Albert-lászló Barabási on thinking in terms of networks. Some of the questions he has been asking and seeks to answer here are:
  • [W]hat does it mean to be part of the network? 
  • [W]hat does it mean to think in terms of the network? 
  • What does it mean to take advantage of this connectedness and to understand that? 
  • [H]ow do you describe mathematically the connectedness? 
  • How do you get data to describe that? 
  • What does this really mean for us?
Some of the implications of this research might be alarming for some. I have no problem with collected data and trying to understand how, when, and why people interact, but I have concerns about what might happen to that data - who is going to use it, and how is it going to be used?

You can listen to the audio link below, watch the embedded video, or read the transcript (the first paragraphs of which are included, but you'll need to follow the title link to read the whole thing).

Audio: Thinking In Network Terms



THINKING IN NETWORK TERMS  

THINKING IN NETWORK TERMS
[ALBERT-LÁSZLÓ BARABÁSI: 9/24/2012]
We always lived in a connected world, except we were not so much aware of it. We were aware of it down the line, that we're not independent from our environment, that we're not independent of the people around us. We are not independent of the many economic and other forces. But for decades we never perceived connectedness as being quantifiable, as being something that we can describe, that we can measure, that we have ways of quantifying the process. That has changed drastically in the last decade, at many, many different levels.
It has changed partly because we started to be aware of it partly because there were a lot of technological advances that forced us to think about connectedness. We had Worldwide Web, which was all about the links connecting information. We had the Internet, which was all about connecting devices. We had wireless technologies coming our way. Eventually, we had Google, we had Facebook. Slowly, the term 'network connectedness' really became part of our life so much so that now the word 'networks' is used much more often than evolution or quantum mechanics. It's really run over it, and now that's the buzzword.
The question is, what does it mean to be part of the network, or what does it mean to think in terms of the network? What does it mean to take advantage of this connectedness and to understand that? In the last decade, what I kept thinking about is how do you describe mathematically the connectedness? How do you get data to describe that? What does this really mean for us?
This had several stages, obviously. The first stage for us was to think networks, only networks down the line. That was about a decade ago, we witnessed the birth of network science. I could say a couple of geniuses came along and did it, but really it was the data that made it possible. Suddenly we started to discover that lots of data that's out there, that we're collecting thanks to the Internet and other technological advances, allowed us to look at connectedness and to measure it and to map it out.
Once you had data, you could build theories. Once you had theories, you have predictive power, you could test that and then the whole thing fitted itself. It suddenly very actively emerged as a field that we now call network science. Going beyond networks, going beyond connectedness, we realized we started to know not only whom you connect to and whom you see and where are your links (the economical, personal, social or whatever they are) but we started to see also the timing of your activities. What do you do with those links? When do you interact?
