May the Best-Connected Node Score! (Or, How I Came to Tolerate the World Cup)

I have to confess I am indifferent to soccer. Until last week, I was mostly annoyed by the distraction brought by the current World Cup.

​And then things changed a bit. Reading Le Monde, I was intrigued by a graphical representation of a complex network. It just so happened to be a representation of the strategy of the Dutch soccer team. This is a simple and clever representation, which—at least, for me—makes soccer interesting.

Why and How Cities Need to Learn Better

Christine Fallert Kessides's picture

During the recent 7th World Urban Forum (WUF) in Medellin, the talk was not just about the hundreds of millions of people coming to cities—but also the tens of thousands of city managers and local governments who will need to manage cities more effectively to unleash the promise of urbanization.  The WBI urban team, together with the Institute of Housing and Urban Studies and UN-Habitat’s Capacity Development unit, convened over 40 partners for a day of reflection on this challenge. 

Such a gathering had happened twice before— in preparation of Habitat II in Istanbul (1996), again in the run-up to the third WUF in Vancouver (2006)—and now on the cusp of the next milestone (Habitat III  in 2016).   It is helpful to consider where we have been and where are we now on this critical (and somewhat slippery) subject, given the 20 years’ worth of perspective in this area.

Policy Makers and Network Science: Time to Bridge the Divide

Last week I attended Masters of Networks, an event that analyzed how a greater understanding of networks can be used to make better policies, especially in the digital era. Many questions built in policy making both from the procedural and substantive perspective involve networks dynamics:

  • How does information spread?
  • Who participates in decision making?
  • How do we collect evidence?
  • Who influences behavior change?

Alberto Cottica, the mastermind behind the event, had a vision of putting two groups of people who traditionally don’t mingle much in the same room – policy makers and network scientists – to see what emerges as a result. Policy makers presented a variety of policy problems, and network scientists helped better frame the problems and address them through applying principles from network theory.

I had the privilege of presenting my perspective of what policy making in the digital era looks like (slides will be put on Slideshare soon). I will summarize below the main points from my intervention, but, more interestingly, reflect on feedback from the group.

My presentation consisted of three elements:

A Murmuration of Starlings

Reporting from TEDGlobal on Radical Openness. I was struck by Don Tapscott’s presentation on Tuesday, which compared the opening up of our knowledge and data as the next step in the evolution of human societies and called it an "Age of Networked Intelligence."  Tapscott then went on to say that the societies of this age can be likened to a “murmuration of starlings,” a term that is used here for a flock. The murmuration moves in a complex interconnected way without a single leader and the flock works together and protects itself from predators (see picture).

What surprised me is that this flock of starlings was startlingly similar to the infographic displayed by the Vibrant Data Project during a presentation by Eric Berlow, a TED Fellow, which describes the network of connections in an “open” environment. Check it out here:

Unique pitfalls in the analysis of networks

Jed Friedman's picture

Network analysis is a burgeoning sub-field in development economics as more and more attention is paid to how individual preferences and behaviors are influenced by decisions in the wider community. One example is the 2007 Kremer and Miguel paper that explores the determinants of take-up of deworming medicine by regressing take-up on the number of connections that the household has with other treated households.

Sudoku quilts and job matches: An experiment on networks and job referrals

David McKenzie's picture

One of the frustrations facing job seekers worldwide, but especially in many developing countries, is how much finding a job depends on who you know rather than what you know. For example, in work I’ve done with small enterprises in Sri Lanka, less than 2 percent of employers openly advertised the position they last hired – with the most common ways of finding a worker being to ask friends, neighbors or family members for suggestions. Clearly networks matter for finding jobs.

Quote of the Week

Antonio Lambino's picture

"We live in a networked world. War is networked: the power of terrorists and the militaries that would defeat them depend on small, mobile groups of warriors connected to one another and to intelligence, communications, and support networks. Diplomacy is networked: managing international crises -- from SARS to climate change -- requires mobilizing international networks of public and private actors. Business is networked: every CEO advice manual published in the past decade has focused on the shift from the vertical world of hierarchy to the horizontal world of networks. Media are networked: online blogs and other forms of participatory media depend on contributions from readers to create a vast, networked conversation. Society is networked: the world of MySpace is creating a global world of "OurSpace," linking hundreds of millions of individuals across continents. Even religion is networked: as the pastor Rick Warren has argued, 'The only thing big enough to solve the problems of spiritual emptiness, selfish leadership, poverty, disease, and ignorance is the network of millions of churches all around the world'...  In this world, the measure of power is connectedness."

Friends for global change

Maria Rodriguez's picture

Aren’t you amazed at how many networking opportunities the Internet offers? Today I started to think about it when I received a Facebook invitation from a friend from Romania that I haven’t seen in over 6 years! How else would I have heard from him again if not through the Internet? This made me realize that nowadays people all around the world, and most of all young people, have very international networks of friends thanks to the Internet and to how easy it is now to communicate and travel. In my case, I know people in almost every continent!
