User Apathy in the Air

I just flew from Newark to Boston and was amazed by the percentage of passengers who were content with watching 30 minutes of repetitive commercials 12 inches from their face.

The United (now Continental?) flight offered a free preview of the in-flight directv service. Having ESPN feeding me the latest NHL and NBA playoff news during the normally tedious boarding process and ascent was an unexpected delight, tiding my ADD mind over until I was allowed to power on my iPhone. However, shortly after the preview ended (and the plea for $ to continue viewing began), I shut down the display.

Twenty minutes later I noticed that everyone else still had their displays on, still watching the directv advertisements flash before their eyes. This got me wondering... are consumers really so lazy that they would rather watch an endless (and repeating) stream of bad commercials rather than figure out how to turn off the screen?  Or are they too dumb to realize that you can even turn it off?  Try to make a guess...then look at this photo of the controller:
Where's the power button?
I wonder if "no power button" was an explicit decision from the airline/directv execs...some kind of sneaky ploy to make more money from having more eyeballs on more commercials.  What do you think?

I guess that isn't too likely, since it fails to pass the most important test in human behavior reasoning:
Hanlon's razor - Never attribute to malice that which is adequately explained by stupidity.

This was an old update that I wrote for my boss.  I wrote it with as many acronyms and identifiers as possible just to test her :-)
Is everyone forced to work with this many TLA or is it just me?

The Stepstone project's transition from the SODA subproject of Eclipse OHF (moving to RT) to OHT is almost complete. We have been working on support for the ISO/IEEE P11073-20601 PAN protocol and are slowly adding support for the various 11073-104xx specializations. Most of this support involves generating the java class model from the ASN.1 model and adding support for the MDER encoding.

We have also began work on a WAN interface prototype using WS-I Basic (SOAP/HTTP with WS-Addressing) to send the XER encoded ASN.1 event reports from the AHD to the RMS (WAN Device). As part of this work, we have analyzed some other web service standards including WS-RX (WS-RM and WS-MC), WS-Event/WS-Notification, WS-Man/WSDM, and others.

One alternative being discussed in Continua is the re-purposing of the IHE PCD protocol (HL7 V2.5 over MLLP--a TCP/IP protocol with some extra framing characters)

Once the data arrives, it is up to the RMS to translate these messages from the IEEE DIM model to HL7 RIM in order to generate a CDA-based PHM (CCHIT approved?) and convert the IEEE nomenclature to the various medical nomenclature standards like SNOMED or LOINC. Once this is complete, the PHM is sent over the xHR (x=PHR, EHR, EMR, etc) interface using IHE XDR or XDM (both from the XDS family). If XDS is used instead, such as across a RHIO or HIE, we will have to deal with handling patient IDs through profiles like IHE PIX/PDQ.
