How Do You Put a Price Tag on a Brand New City? – Jobs & Economy – The Atlantic Cities: “The infant nation of South Sudan has a big construction project in mind. Officials are hoping to build a brand new city to act as its capital. The cost of the project was recently estimated at $940 million.”
OK, cost of 1 stadium in Minneapolis to serve 8 games a year to replace existing stadium > cost of capital of entire country.
Susan Fecht @ SciAm: Track Record: Do Major Urban Subway Networks Evolve along Similar Patterns?:
“No two subway systems have the same design. New York City’s haphazard rail system differs markedly from the highly organized Moscow Metro (above), or the tangled spaghetti of Tokyo’s subway network. Each system’s design is the result of many factors, including local geography, the city’s layout and traffic distribution, politics, culture and degree of urban planning.”
Nice summary of recent research by Roth, Kang, Batty, and Barthelemy “A long-time limit for world subway networks” in Journal of the Royal Society: Interface (which might be behind a firewall if you don’t have library access)

From February: GTI/UTC Lunchtime Lecture Series – Dr. David Levinson – YouTube: “Network Structure and Travel Behavior”
(57:22)
Abstract: Transportation networks have an underlying structure, defined by the layout, arrangement and the connectivity of the individual network elements, namely the road segments and their intersections. The differences in network structure exist among and between networks. This presentation argues that travellers perceive and respond to these differences in underlying network structure and complexity, resulting in differences in observed travel patterns. This hypothesized relationship between network structure and travel is analyzed using individual and aggregate level travel and network data from metropolitan regions across the U.S. Various measures of network structure, compiled from existing sources, are used to quantify the structure of street networks. The relation between these quantitative measures and travel is then identified using econometric models.

The Scholarly Kitchen: The Emergence of a Citation Cartel :
“In a 1999 essay published in Science titled, ‘Scientific Communication — A Vanity Fair?’ George Franck warned us on the possibility of citation cartels — groups of editors and journals working together for mutual benefit. To date, this behavior has not been widely documented; however, when you first view it, it is astonishing.
Cell Transplantation is a medical journal published by the Cognizant Communication Corporation of Putnam Valley, New York. In recent years, its impact factor has been growing rapidly. In 2006, it was 3.482. In 2010, it had almost doubled to 6.204.
When you look at which journals cite Cell Transplantation, two journals stand out noticeably: the Medical Science Monitor, and The Scientific World Journal. According to the JCR, neither of these journals cited Cell Transplantation until 2010.”
