Harry, I'm putting this in a new thread because there's actually a lot of it, and it's not going to copy well from the PDF files in which I've got it most conveniently, because it's all in tables--and because there are a lot of things about it that you're going to have to tailor to your version of the world.
Introductory Notes
There is one advancement table for the Alpha version and a separate one for the Beta version.
Attributes are listed first, but they take longer to improve; skills follow.
Officers have skill and attribute improvements for being officers, in addition to those they get for being members of a department.
I'm giving you attribute and skill improvements for both worlds, but only for medical personnel.
The attribute system is such that in the specified time frame the character will gain one intensity, but only within the levels for which the advancement is sufficient. That is, the work conditions will improve the resistance of all crew members to a maximum of 1@10 (at level one), but for deck hands, whose conditions are harsher, they may improve (at level two) to 2@10.
The skill system is given in skill marks or credits earned per time period. Remember that a character loses extra skill marks if he would advance two intensities--that is, if a character receives five marks, he improves from 1@1 to 1@2 and loses the other four marks, or he improves from 2@1 to 2@2+1 mark, or he improves from 3@1 to 3@1+5 marks.
Alpha Attributes
Resistance improves one intensity at level one every 800 days, because it does so for everyone in the crew due to the harshness of the shipboard conditions. Deck hands and pilots improve at level two, but others do not.
Hand/Eye improves one intensity at level one every 800 days, because of the medical work such as stitching and the examinations that have to be done.
Intellect improves one intensity at level one every 2000 days because of the constant problem-solving nature of the job.
Education Level improves one intensity at level one every 1500 days because of the continuous learning all medical personnel face in performing their jobs.
Will Power improves one intensity at level one every 2000 days, because it does so for all crewmen due to the harsh conditions and hard life; it continues at level 2 for deck hands and top officers only.
Beta Attributes
Stamina improves one intensity at level one every 800 days because it does so for all crewmen due to the conditions; security, deck hands, and top officers get this benefit at level 2 also.
Resistance improves one intensity at level one every 800 days for much the same reason, and again deck hands and security and top officers get greater benefits.
Density improves one intensity at level one every 1000 days due to the gravity fluctuations aboard ship and the varying conditions of planets visited.
Hand/Eye improves one intensity at level one every 600 days due to the medical work, which includes various types of surgical procedures.
Intellect improves one intensity at levels one, two, and three, every 3000 days, because of the nature of the work in problem solving.
Education Level improves one intensity at levels one and two every 2000 days because of the constant learning medical professionals undergo.

There may be some things missing; none of my test players ever played a doctor, although I had a navigator and a couple of security people.

And THAT answers the world-building question I was gonna ask fairly shortly-handling increases just from work, as well as the one about mental attribute increases.
