Why prices often show less variation

Given some of the comments on that blog post, and the fact that the teachers conferences were being held last week, I decided to look in a little more depth at the education sector. How much do teachers in Ireland earn? How does this compare with other people in Ireland?

Yet another paper shows the hot-spot is missing. Ocean Acidification — a little bit less alkalinity could be a good thing In Brief: The oceans are not acidic, and will not become acidic in the foreseeable future.

Many of the fears and alarming scenarios are based on models. Many scary headlines are based on studies of extreme pH values beyond the range of anything realistic. Incredibly, hundreds of studies show that for pH changes that we are likely to encounter in the next years, there is arguably a net benefit to underwater life if the oceans became a little less alkaline.

There are estimates that the pH of the ocean has shifted about 0. Four pH units means 10, fold change in the concentration of hydrogen ions.

Yet still someone thought it was worth studying what would happen if, hypothetically, that happened. They reason that any change beyond 0. Some headlines come from studies of hydrothermal vents where CO2 bubbles up from the ocean floor. Not surprisingly they find changes to marine life near the vents, but then, the pH of these areas ranges right down to 2.

They are an extreme environment, nothing like what we might expect to convert the worlds oceans too. Marine life, quite happy about a bit more CO2?

Studies of growth, calcification, metabolism, fertility and survival show that, actually, if things were a little less alkaline, on average, marine life would benefit.

There will be winners and losers, but on the whole, using those five measures of health, the reefs are more likely to have more life on and around them, than they are to shrink. Percent change in the five measured life characteristics calcification, metabolism, growth, fertility and survival vs.

How can this be? First, marine life evolved under conditions were most of the time the world was warmer and had more CO2 in the atmosphere than it does today. That said, the dots in the graph above represent study results, and the ones below zero tell us there will be some losers, even though there will be more winners above zer0.

Thirdly, watch out for some of the more devastating headlines which also come from studies where researchers changed the pH by tossing hydrochloric acid into the tank.

Chlorine, as they say, is not the same as the gas nature breathes — CO2. The graph above is just one of many on their results and conclusions page. Yes, we should watch and monitor the oceans careful. No, there is no chance the Great Barrier Reef will be gone in the next years:In Brief: The oceans are not acidic, and will not become acidic in the foreseeable future.

From the standpoint of anthropology and sociology, dating is linked with other institutions such as marriage and the family which have also been changing rapidly and which have been subject to many forces, including advances in technology and medicine. How can we find prices of popular items through the centuries to make comparison charts?

This is an evisceration.
