...nitrogen oxides and particulates fell by 16 per cent. A fall in the number of cars and an increase in speed of 4 kilometres an hour were responsible for three-quarters of this fall, with greener technology in cars making up the rest. Carbon dioxide emissions fell by 19 per cent. Even an increase in the number of buses, whose diesel engines are among the worst polluters, could not offset the drop, partly because modern buses are fitted with particulate traps.
Just some musings about air pollution in honor of Thanksgiving. And no, I don't really get the connection, either.
First, CNN reports that five years worth of negotiations between state and local agencies and airports have failed to result in emissions cutbacks for airports.
The article quotes a Taipei city official who talks about the Wi-Fi project as not only beneficial to businesses but also to improve residents' quality of life [Italics mine].
They looked at 95 cities; here's the salient bit from the abstract:
A 10-ppb increase in the previous weekï¿½s ozone was associated with a 0.52% increase in daily mortality (95% posterior interval [PI], 0.27%-0.77%) and a 0.64% increase in cardiovascular and respiratory mortality (95% PI, 0.31%-0.98%).
Without a fundamental shift by government to address the fundamental policies that exacerbate urban sprawl, building new light rail systems and subsidizing select projects alone will have l
Photomontage is a visualization technique that is becoming increasingly popular as a tool to demonstrate what the future might look like under different design or build-out scenarios.
The New York Times had a more informative map that took into account population density.
A July, 2003 research paper from Carnegie Mellon University, co-authored by Chris Forman, Avi Goldfarb and Shane Greenstein, explores the extent of commercial adoption of the Internet in the nation's 50 largest metropolitan areas.
The paper --
"How did Location Affect Adoption of the Commercial Internet?-Global Village, Urban Density and Industry Composition" --explores the connection between industry composition and city size in explaining business use of the Internet.
[T]he category in which Bush showed the most significant gains over the year 2000 was urban voters (who made up 30 percent of all voters), among whom Bush polled 9 percentage points better than in 2000. Bush did even better among voters in the largest cities, picking up 12 points on his 2000 performance.
On the other hand, the New York Times has a bunch of maps on the back page of its special Election section today (which I can't find a link to; sorry) says that Kerry's margins in cities were actually much larger than Bush's margins in rural areas.
"DeVaan's modified van performs a similar trick. Its mast communicates with any of the wireless-Internet transceivers Implex.net has put atop Twin Cities skyscrapers, including Wells Fargo Place in downtown St. Paul and several in downtown Minneapolis. Presto! The van is Net-connected. All DeVaan has to do is plug in his Webcam and point it... In addition to serving as a roving eye, the van can provide high-speed wireless Internet access within a 1,500- to 2,000-foot radius."
"WazTempe, a Tempe, Ariz.-based wireless-Internet pro-vider that is turning the city into one big Wi-Fi hot spot, has come up with a clever way to plug gaps in its network: golf carts equipped as Wi-Fi repeaters. The Waz Mobile Units transmit in a roughly one-mile radius and can integrate with the rest of the city's wireless "mesh" infrastructure."
"The software will in the near future be made available at little or no cost. (This offering will include Scenario 360 v2.1 and later, and SiteBuilder 3D for CommunityViz.) We are in the process of exploring the logistics of this exciting new mode of distribution."
"There is a decent screen magnifier in Windows XP, which also includes a text-to-speech tool called Narrator. It is pretty limited and is only available in English, but it provides a useful tool in Notepad, Wordpad, Control Panel and Internet Explorer, as well as the Windows desktop and Windows setup."
You can launch Narrator easily by pressing the Windows logo key and the U key, which also lets you start and stop the tool.
At least, that seems to be what the New York Times remembers. Here's the part I'm talking about:
The Microsoft Home is more like a concept car, a design to dream about. Microsoft has imagined a dream house before: 10 years ago the company unveiled its first such demonstration home. At the time Microsoft's designers were intrigued by interactive television, a technology that never became the next big thing.
One of only a handful of cities in the nation to try it, Chaska -- just southwest of Minneapolis -- plans to have most of the city's 15 square miles Wi-Fi operational by the end of October.
"We firmly believe that the Internet is going to be just as much a part of everybody's future as the telephone or electricity is and we want to make sure that everybody has equal access to it," says Bradley Mayer, Chaska's information systems manager. "We wanted to ensure there was some sort of broadband activity that could be affordable by our residents."
"The Linux server now in use by the county helps manage its finances...employees who track the county's money log on to the server through a Web browser...Because there's only one program for the server instead of hundreds of copies for each computer at employees' workstations, the county also saves money on software licensing..."
The Internet can be a great way to supplement public meetings and get more people to participate in registering their opinions and preferences for planning alternatives. (Of course there are equity issues but that's a discussion for another piece.)
The image below is an example of a question asked on the online visual preference survey used by Midtown Columbus Georgia. Results from the survey, gathered both in public meetings and online, are being used as a foundation for guiding the future planning recommendations for Midtown Columbus.
