Human Factors in Space Engineering

http://www.eraualumni.org/s/867/index.aspx?sid=867&gid=1&pgid=252&cid=1661&ecid=1661&crid=0&calpgid=15&calcid=889

ERAU Daytona is gaining support for a space transportation R&D institute. Among the fields the institute will be pushing is HFE in space flight. I'm still working on getting a contact for more info, but this is definitely interesting.

As a note, in Doc Travis's latest book "Introduction to Rocket Science and Engineering" (Travis S. Taylor, CRC Press. Copyright 2009) he covers all the basics of rocketry and space flight. He covers government acquisition phases and how detailed such acquisition programs need to be. He even slightly hints at the need for human factors... but there is no HFE chapter. :(

Maybe I should write it for him? XD

Lets switch gears for a moment.

Safety.

What is safe? Can something ever truly be safe? Should we define a new word (safe-ish) instead? Is there a reason for everything to be "safe".

What would the shifts be. Instead of the most common last words being "hey watch this!" perhaps we could change it to "well, it was safe-ish".

:D

Yerkes-Dodson Law

I'm being evil today and giving everyone homework.

http://psychclassics.yorku.ca/Yerkes/Law/

This paper is the work that eventually led to the "inverted U" Yerkes-Dodson law of human performance. The law posits that as stimulation increases, arousal (think alertness not the other, more fun version) increases to a point. After that point further stimulation theoretically results in a decrease in arousal. Sounds valid on the face of it (I love that phrase). There are issues with the initial paper (obviously the first issue would be that the study involved mice, not people).

Now others have done studies trying to apply the conclusions of this paper to humans (and the studies are arguable as to their validity). Your homework is to read this original work and tell me what some of the other issues are with the conclusions.

:D

On politics...

Okay, for the most part I'm too darned busy showing the flaws in modern pseudo-science to want to do much on politics here but...

They moaned and complained as George Bush orchestrated one of the largest expansions in the US Government in history. They whined about his policies, the war, the money he spent, and ultimately about the economic crisis (even though the evidence points to the possibility (I won't say fact here because I'm too lazy to find a citation right now) that the Dem's are the ones that finally caused the housing collapse).

Someone please explain to me something. If what Bush did was so bad, how is Obama doing even more than that better? Is a massive increase of the items that made Bush so disliked really the hope and change the American people wanted? Really?

We're leaving Iraq (were gonna do that anyway) but we're pumping up Afghanistan with out a plan. (At least "the surge" had a communicated plan behind it along with a change in command).

We borrowed and over-spent ourselves into an economic crisis... now the solution is to borrow more and spend EVEN MORE! Huh? Something does not compute.

Obama touted "hope and change"... The increase in people who voted for him going to gun stores and saying the reason is they're afraid of him! Terrifying!

But here's the most frightening thing. Nobody can talk to a person with a differing point of view anymore because we no longer can even understand the ideas of the other side. You must have common ground to hold meaningful political discourse. We seem to be engaged in political tit-for-tat.

It is time to kick everyone out of office (on both sides) and hold some meaningful discussions. We're all Americans, we'd better find some common ground quick.

It is conspicuous

Have you ever noticed that growing up everyone told you that your teachers knew what they were talking about... and now as an adult you realize they were full of it? In fact, it sometimes seems that those who teach in the grade schools have an IQ that is lower than the dumbest kid in the class.
