Spatial data mining in local finance
Data mining is the automatic process of sorting through large amounts of data and discovering patterns. It has been described as "the nontrivial extraction of implicit, previously unknown, and potentially useful information from data" (Frawley et al 1992). For an introduction to data mining, see presentation slides on the website of Professor Robert Stine, from whom I learned the topic at ICPSR.
Spatial data ming is the application of data mining techniques to spatial data, with the objective to discover spatial patterns. Still at the early stage of development, spatial data mining is considered a new field with boundaries yet to be defined. In general, spatial data mining focuses more on large data sets and tend to be exploratory in nature, with heavy reliance on newly developed computational powers (Professor Guo).
In a recent project I am using exploratory spatial data analysis (EDA) to visualize and analyze spatial patterns of inter-local fiscal relations with a comprehensive database that include hundreds of fiscal variables for all local governments in Georgia. This may be an example of spatial data mining in the study of public finance and local government management. I am eager to meet others with similar interests. (Click here to get my presentation slides on ABFM 2007.)

Good post -- and also the how and how to never pitch. I'm embarrassed that a great many in my field just do not get it.

You may try saving as PNG (lossless as opposed to JPG), or the other thing that I can think of is that you could need to rasterize your smart objects, and after that save it being a PNG. Be careful to not save over your original PSD, because once you rasterize, you won't be able to un-rasterize.

Excellent tip. Many thanks a lot. I only have one particular question though. Many of the above works for me but 1 thing I cannot upload my videos using iweb. When i select a video to upload the iweb function is dimmed. I'm using iweb 06. Any suggestions?

I actually like this approach and use it for most of what I do online. But I get into all-or-nothing phases where I won't even start on a project if I do not think I can make it turn out perfect. In no way starting is usually a waste of a superior idea and opportunity.

Interesting post. I am curious about your recommendation for "leaving your Twitter handle or Facebook fan web page URL rather than linking back again to your site." I've normally considered that leaving your website address is 1 way of adding a few more links to your web site. I'm curious about why "its better" to leave a Twitter handle and forgo that potential website link. Do you might have a blog publish the consider a close look at this strategy?

Hello. I noticed your website title, "Fiscal Issues & Geeky Stuff -
Hubert H. Humphrey Institute of Public Affairs" does not really reflect the content of your web page. When composing your website title, do you think it's most beneficial to write it for Search engine optimisation or for your audience? This is one thing I've been struggling with due to the fact I want good search rankings but at the same time I want the best quality for my visitors.

In my experience V2 has been everything I could have hoped for. My whole ordering process went smoothly from beginning to end. I did A LOT of research before finally settling on V2 as my e-cig supplier, and since my starter kit arrived (over a month ago) I have not had a cigarette! V2 has many different flavors to choose from and so far all that I have tried have been fantastic. Their carts last at least as long as a pack of traditional cigs would and their batteries hold a long charge. I was also really impressed by the amount of vapor V2 e-cigs produce...very thick and smoke-like. I honestly do not miss cigarettes at all! In fact it feels like I am still smoking. They have many different batteries/cartridges/accessories to choose from and they have managed to mimic the whole sensation/feeling/throat hit of smoking an actual cigarette. I recommend V2 strongly to anyone interested in trying e-cigs. Not only am I saving money it is nice to know that I may also be saving my life. I have read where some had problems with V2's shipping times and I can say that I have never had any problems at all. V2's customer service is outstanding (no, I do not work for V2) and they go out of their way to please their customers. Not only is the product and customer service great but they are always running sales and have discounts...V2 has truly changed my life and it is wonderful to now consider myself a "non-smoker"!!!Jeff

I'm confused as to the Census' definition of "origin" and "race". When will "American" be considered an origin? Maybe in the 1790's, capturing someone's origin, such as Germany, Sweden, Mexico, Spain, etc. may have been important considering the number of immigrants that were entering the United States; however, I do not see how it is relative now considering 95% of the people completing the census were born in America, therefore their origin is American, which is not captured.
I have spoken to several friends that are Hispanic (which is a race that is not captured); however there parents were born in America, they were born in America and therefore they consider themselves as Americans, not Mexican Americans, so how do you expect them to answer question 8? Who do you expect them to answer question 9; White? What is the definition of "White"? Why is "Mexican American" considered an origin, but "African American" considered a race? How do you expect persons of mixed race to answer questions 8 and 9?
Your origin is where you came from and your race is who you represent. And I think it is about high time the government starts capturing this information more accurately.

Hi Andrew
I would say the biggest challenge I had to overcome in college would be accepting that I would have no friends. Almost all of the students ignore me because they are too ignorant or afraid to talk to me. I t used to bother me, but now it doesn't because if they are too rude to talk to me, I don't want them as friends. Besides, I am 31 now, so I have nothing in common with most of the other students!
