There would be a very simple measure the CDC could impliment to absolutely determine if there was a link, change the age recommended for vaccination schedules while simultaneously tracking the precise age for the population in which autism first presents itself. If they change the vaccination schedule by delaying 1 year the normal course of vaccines and find that the median age of the onset of autism in new patients changes, then they have incontrovertible proof. Most of these early childhood diseases are also extremely rare in the United States and delaying the age of vaccination by one year would have very few if any consequenses.
Prices have come back to normal or bottomed out in all areas except NY and DC.
There are two general very good statistics to use regarding this, price/rent ratios and also the case shiller 20 city index. If you look at the case shiller 20 city index for the last 20 years you'll see that typically real estate increases in value by around 25%-50% every 10 years. Trending the index from the November 2008 numbers to February you'll see that we are very close to 125 to 150 for this index or will be reaching it by May.
Looking at the price/rent ratios is another independent means of seeing this value, and again, trended out you'll see that within the next two or three months we'll be back to normal price/rent ratios we've seen in the last 30 years. DC and NY seem to be experiencing the same fall, but lagging the rest of the index by a year or so.
Even looking at your first link http://www.ritholtz.com/blog/2009/02/homes-still-too-pricey-to-stabilize/ you'll see that the most meaningful statistic is the ratio of median home price to median income has since 1980 been around 3.5, and trending that graph out to the present, we are back at that 3.5 level.
I saw that we were in a real estate bubble from these same statistics I've given here back in 2003, so I've been tracking this for a while. What we need to worry about now is shooting ourselves in the head for fear of what is yet to come when literally the worst is over.
Peace
It's as it people think that being homeless is itself a sin, something that needs to be redressed by sermon and admonition. Christ himself was homeless. I don't understand present Christians, gilded Churches, parking lots full of Lexus and Mercedes cars. Perhaps they should simply content themselves with feeding their sheep. If he were to come again I wonder if he would actually enter in the building or sleep under the bridges with those who needed him the most.
Just did a bit more research. There are four types of Dengue fever. The problem is that if you vaccinate against just one of the forms and get bitten by a mosquito carrying a different form, there is a higher likelihood that you will then contract the hemorrhagic fever. Humans are the only vectors, it is species specific. It also appears that the four forms of Dengue have been around since they were first isolated in the 1950s.
That's something I wondered too. OK, looking at the worst case. Millions of viruses occur with and infection and thousands of mutations. Any virus that would be transmitted with a mosquito living a shorter life span would logically be a faster growing virus. If it was transmitted to person, there would probably be fewer of the viruses as their reproduction time would be limited by the mosquitos shorter life span, and therefore less likely to create the disease. But if the disease did occur, it would be a more virulent form as it was introduced successfully by a smaller number of viruses. So the worst case, in my uneducated guess, would be a faster reproducing, more virulent
virus. Either way this virus gets my nod as the nasty boy on the block, in it's regular form it's called bone break fever because of the pain, through the internal and external bleeding into it with the hemorrhagic form and it's something that will keep me out of the jungles. We also have a far bigger human population down there then ever before due to lots of coastal tourism. Michigan anyone?
Hmm, looks like that's long enough for the mosquitos to reproduce, so they couldn't develope a gene for resistance. Clever indeed. When I was cave diving in Mexico a local guide mentioned all of the guide contracted had contracted the disease the month before in the Yucatan, including himself. In 1995 Mexico had 70 cases, in 2001 it had 1781, in 2007 it had 27000. Now it's starting to mutate to the hemorrhagic fever with 5000 cases in Mexico. Hemorrhagic fever is the horror movie kind, the bleeding from the eyes type that was thought to have actually wiped out over 90 percent of the population of Central America in the 1500s. I'd say the numbers of general dengue fever are vastly under reported. People in rural Mexico know there is no cure, so they don't go to the hospital and spend the money and thus they aren't counted in the official statistics.
