The small world phenomenon in social networks is quite a surprising property when one first learns of it [wikipedia: small world phenomenon]. Six degrees of separation - the idea that each person is connected to every other person by a path of length 6 on average - is quite remarkable. Yet we observe […]

The link above discusses how a nation’s or corporation’s culture can affect buyer seller relationships and whether a buyer repurchasing with a particular seller is affected by culture. The researcher’s surveyed various corporations in the United States and Latin America.
This is not to say that key characters such as strength of […]

 ECON 204 has thus far been presented as an introductory course, with most students being introduced to the general principles of networks for the first time.  With this in mind, it is natural to assume that we would have little understanding of network systems of any significant complexity.  However, the […]

I wanted my first blog posting to get back to the roots of graph theory because the mathematics behind graphs and the number theory behind the mathematics is what fascinates me the most.  “The Seven Bridges of Konigsberg” and Euler numbers are one of the base principles when studying the math and number theory behind […]

In the article, Cash In On Your Social Network, Joanna Glasner looks at online recruiting services, such as Jobster and H3.com that uses social networks to fill job positions, by offering cash for referrals and invitations by and for prospective job applicants. Companies such as Starbucks and Nordstrom use Jobster to have employees refer […]

 
BoingBoing, Digg, Fark, MetaFilter, Protrade, Wikia, YTMND. Aside from being some of the biggest powerhouses on the web, what else do these media giants have in common? Over the past few years, these websites have risen up to attain rather influential positions in […]

In their paper, Last-Minute Bidding and the Rules for Ending Second-Price Auctions: Evidence from eBay and Amazon Auctions on the Internet Alvin Roth and Axel Ockenfels examine the effects of different rules on the ending of second price auctions. While eBay uses a fixed end time for its auctions, Amazon’s system automatically extends an […]

Note: This was also posted on my own blog: http://aysz88.livejournal.com/27137.html . It may look better there.
In the February 16, 2007 issue of Science, Brendan J. Frey and Delbert Dueck apply “message-passing” networks to a problem that doesn’t seem particularly natural in that context: how does one cluster large numbers of objects, and then find […]

In my previous post, I had mentioned an online revolution known as web 2.0 and I had only created a directed edge from this blog to the wikipedia page. While I was reading one of my subscribed blogs, Presentation Zen, I stumbled across this post which shows how text can be used for an effective […]

In the CNET article found here the author discusses how the recent boom in network research has led to startling revelations in the mathematics of network theory. Network mathematics, a field in the past studied primarily by physicists and mathematicians, is growing in complexity thanks to the collaborative efforts of sociologists, statisticians, and many […]
