My instinct is that the people surveyed may have been landlords of large apartment complexes or business owners where people do not live who would be more concerned about saving a dollar than safety. I feel that it would be interesting to know both the time span between the earthquake and the survey, the average amount of damage done to the area (a few buildings vs. a whole section of the town), and the general wealth of the area. Additionally, if the buildings were 1 story houses or 20 story apartment complexes would have a great impact on how to rehabilitate the buildings. The conclusion seems obvious- lower prices increase the likelihood that someone will wish to upgrade their seismic resistance.<br /><br />In the realm of decision trees I think this is an interesting way to go about finding solutions to a natural disaster. It takes a potentially panicked population and logically explains various decisions complete with costs and frequency of potential future earthquakes. <br />Anonymoushttps://www.blogger.com/profile/07670586587477690796noreply@blogger.comtag:blogger.com,1999:blog-4509736829271344872.post-32035998149251895022013-03-12T20:09:21.209-04:002013-03-12T20:09:21.209-04:00To clarify some points the region in China that wa...To clarify some points the region in China that was studied did have a frequency of having decent measured earthquakes according to the Richter Scale, meaning that earthquakes in the area were not uncommon occurrences. In terms of the earthquake event, the earthquake that totaled 88,000 deaths occurred in 2008. The study was completed by the authors in 2010. In the article it did not clarify how many building owners chose to upgrade their homes, but rather the researchers gave the most viable response based on the information presented in the decision tree.

As Ethan mentioned, it would be useful background information to note whether this area saw frequent earthquakes or if they were a rare occurrence. Either way it is odd after the deaths of over 88,000 people the individuals would not be more interested in safety. Furthermore, it seems likely the study was conducted fairly quickly after the earthquake took place. Directly after an event people are oftentimes more sensitive and willing to take drastic measures with an increased interest in safety. It would be useful to know the amount of time between the earthquake and the study. <br /><br />Due to the heavy weight finances played, the use of the DMT to economically justify the conversion to the highest seismic resistance may, in the future, save many lives. It would be interesting to find out how many individuals chose to upgrade to the highest seismic resistance as a result of the findings the DMT provided.Angie Andersonhttps://www.blogger.com/profile/11737384901278780197noreply@blogger.comtag:blogger.com,1999:blog-4509736829271344872.post-7987841173078391432013-03-11T15:03:05.712-04:002013-03-11T15:03:05.712-04:00This is an interesting topic to use decision tree ...This is an interesting topic to use decision tree analysis on. It is also interesting how the DMT used economic justification rather than safety as the end point of the model. Rather than have the three decisions end with how much they increased safety, they based it on an economic incentive. I also imagine one of the deciding factors in using economic benefits rather than the safety benefits is the frequency of earthquakes in the region. If the frequency was high than I would guess that costs would not have been as important of an issue.Anonymoushttps://www.blogger.com/profile/07243687512381833354noreply@blogger.com
