Phase 4 (2013-2015) Follow-Up Questionnaire
This follow-up focuses on health changes and updating important covariates such as smoking and family history of disease. We invited approximately 70,000 Phase 3 eligible subjects to participate regardless of whether they participated in the Phase 3 interview. For the first time, in order to recover crucial data on their health histories, we also interviewed the next-of-kin for participants who were incapacitated or deceased. The data collection was done primarily via mailed questionnaires, supplemented by computer assisted telephone interviews with those who did not respond to the mailings. Approximately 61% of eligible AHS participants or their proxies completed the Phase 4 survey. This Phase 4 data collection will greatly facilitate research on non-cancer chronic diseases, including diseases of aging, for which there are no registries.
The FCC has allowed Americans to connect any device and any application to the 22 MHz of radio spectrum that people are calling the 700 MHz band. The FCC did not include a wholesale condition, which would have required the owner of the band to resell bandwidth to third parties who could then service the end user. Google argued that the wholesale requirement would have stimulated internet competition. As of 2007, 96% of the country's broadband access was controlled by DSL and cable providers. A wholesale condition could have meant a third option for internet service.
