Save Tulane Engineering – A Rally in Vain

Only one day after the announcement from Tulane (renewal.tulane.edu) that most of engineering would be cut, and the remainder merged with the sciences in the new Science and Engineering department, there’s already a counter-movement.

As much as I admire the dedication of those involved in the Save Tulane Engineering blog and movement, it seems to me to be a rash and emotionally driven plea. After months of deliberation, a group of people far better informed than the student body about the state of the university has made a decision about what will stay and what will go. It seems to me preposterous to think that Dean Altiero, who is to be the new dean of the school of Science and Engineering, would not have been informed of the decision process. It’s evident to me that this was not well-considered, given this quote from the letter:

President Cowen should have spoken to Dr. Altiero, Dean of Engineering, before making the decision to effectively cut our entire department.

In all likelihood, he is the one who decided which departments to axe. Further evidence of the emotional attachment and hubris in the letter abound, such as this bit:

Biomedical, Mechanical, Civil, Chemical,Electrical ,Computer Science, and Computer Engineering students are the most intelligent and diligent students in the most respected disciplines at Tulane.

I’m certain that some people from other departments would disagree. Which departments should be axed, then? Would they rather have a school full of financially crippled departments than no departments at all? This is a fight for the very survival of the university, and by no means do the current measures even assure that.

It could easily be said that I am biased — that because Biomedical Engineering is one of the two departments that will remain in Engineering, I am not properly concerned for the welfare of others. That may be the case, but I think that may leave me in a more objective position to consider the situation. I have watched the drama unfold as the Tulane School of Medicine has gone through similar turmoil, as rumors and opinions spread and blossomed like wildfire through the student body only to be found false after tempers have flared.

I will not sign the petition to change this decision. I feel that at this point what is needed is dialog with the administration, with our dean, and with the president. It is impossible for those railing against these changes to have been fully informed. I expect more of my fellow engineers — people whose lives and livelihoods are founded on the application of reason and knowledge in the process of solving problems. For instance, from the letter:

If you, or anyone else have statistics regarding Engineering at Tulane such as per capita earnings, grant numbers, donation numbers, or scholarship recipients please let me now.

Be careful what you ask for — you may get it. The programs that were cut also happen to be some of those in the most financial trouble, with the least research productivity. I can’t say for certain that this is the sole driving force behind the changes — I suspect there’s more to it — but if the desired statistics are acquired, they probably will undermine the “Save Tulane Engineering” movement rather than support it.

Finally, I should say that it’s easy to point out what you view as the failings of others. I do it in this very post, to some degree. What’s important is to offer a solution with your criticism. As a solution, I propose that we move on, find other places to go, and let things settle as they are. I also propose that if a strong case can be made for the preservation of one or more departments, that case should be pressed. However, I have not thus far seen any such cases. I have only seen pleading and emotion. If the “Save Tulane Engineering” movement is to be productive, it must be more constructive. It must offer concrete solutions based on real numbers. Simply pointing at other parts of the university and crying, “but surely we are more valuable than them: let them go instead,” is far from constructive. Should something appropriate and constructive be proffered, I may then be persuaded to support it with my signature.

The Game of Looking Productive: Optimization by Nuclear Engineers

I found this on Slacker Manager today, and I had to share it. You should read the whole thing (link at the end), but here’s an excerpt:

Mike:
I agree. Now, why is it that we are considered above average performers, but we could do better? I see three possibilities:

1. We throw in enough good stuff, and seem eager enough to do a good job, that our slacking is not noticed.
2. We are way above average, and even our slacking is above average.
3. We aren’t slacking as much as we think we are.

What do you think?

Marc:
i think its a combination of the three. if i had to correlate constants, it would go something like this:

Reason = C1R1+C2R2+C3R3
where Ci= a constant with the property SUMi(Ci)=1

R1=”We throw in enough…”
R2=”We are way above…”
R3=”We aren’t slack….”

in my opinion,
C1=.7
C2=.1
C3=.2

Mike:
good thinking with equations. I think we are getting somewhere. more equations:
Vi equals the value of Ri to other people’s perception, and
Ei equals the relative effort of performing Ri, and
please note that I have changed Ci from a constant to a variable.
PERCEPTION = C1*R1*V1 + C2*R2*V2 + C3*R3*V3
EFFORT = E1*C1 + E2*C2 + E3*C3

I would say that we are good at maximizing PERCEPTION while minimizing EFFORT. The question is, why are we good at this, and why can’t others do it as well as we can? Do people not realize that this is a sort of game?

More details

I hadn’t seen this bit before. This is very bad.

The Faculty of the Liberal Arts and Sciences and the School of Engineering will be reorganized into two schools: the School of Liberal Arts and the School of Science and Engineering. A total of five programs—Civil and Environmental Engineering, Mechanical Engineering, Electrical Engineering and Computer Science, Computer Engineering and Exercise and Sports Science—will be eliminated. Students in these programs will have the opportunity to continue their studies at Tulane if they can finish degree requirements by May 2007. Otherwise, they will be offered assistance in selecting another major at Tulane or transferring to another institution.

Survival to Renewal: Tulane University

This leaves Biomedical Engineering ADDENDUM – and Chemical Engineering. I guess we’re “world-class excellent.”  Wow.

Bad news for Tulane

Tulane lost a ton of money during this whole hurricane situation. I’m sure renting cruise ships as residence halls isn’t helping to stem the financial hemorrhaging.  Now comes the belt-tightening.

If your department isn’t rocking the proverbial casbah, you’re out the door:

The university will focus its undergraduate, professional and doctoral programs and research in areas where it has attained, or has the potential to achieve, world-class excellence. It will suspend admission to those programs that do not meet these criteria.

Survival to Renewal: Tulane University

I’m now very curious about the definition of “world class excellence”…  Just how bad is it? Here are some numbers:

The financial recovery aspects of the renewal plan address the budget shortfall the university anticipates in the wake of Hurricane Katrina and will result in the phased elimination of approximately 50 faculty positions in discontinued undergraduate and professional degree programs. Another 180 faculty positions will be eliminated at the medical school as a result of the decreased population and changing health care needs of New Orleans.“I deeply regret that employee reductions were necessary to secure the university’s future,” said Cowen. “We have tried to make the reductions as strategically and humanely as possible, recognizing the hardship it places on those whose positions have been terminated.”

Survival to Renewal: Tulane University

Not very good at all.

The Scientific Method, and how Intelligent Design Doesn’t Fit It

If you’re not familiar with the scientific method, or if you need a refresher, please see the article linked below from Wikipedia.

Scientific method – Wikipedia, the free encyclopedia

The heart of the scientific method is the multi-step, sometimes iterative process shown below:

From the wikipedia article linked above

Really, the whole crux of the Intelligent Design (ID) debate rests in step 3. Intelligent Design does not form a hypothesis.  A hypothesis is a statement of what is thought to be the case, worded in a falsifiable way.  I actually have a problem with the list above. Perhaps step 7.5 should be “Confirm or deny the hypothesis.” There are technical issues here involving what are known as “null hypotheses,” but I don’t remember them, and they’re not strictly relevant to the rest of my point. Here are some possible hypotheses:

  1. Water is composed of hydrogen and oxygen
  2. My shoes are black
  3. Things lofted into the air will fall back to earth
  4. I was a cow in my previous life
  5. Every object with mass bends spacetime
  6. The sky is green during the day
  7. The living soul of a human is established at conception

Can you pick out the ones that are not actually hypotheses? I’m having a really hard time with this. I’m focused on Intelligent Design, so I tend to come up with non-hypotheses that relate to ID.  I can’t think of many other non-hypotheses, as most things can now be tested and investigated to the extent of support or falsification. Appropriately, most of the non-hypotheses that I can come up with are politically charged. Do you see the connection? They’re politically charged because nobody can ever prove whether they are true or not, and so what you end up with is a bunch of arguing on a national and global scale, over things which can never be proven. By the way, the non-hypotheses are numbers four and seven. Even if the others are incorrect, they are testable — falsifiable.

This, as I see it, is the end of the Intelligent Design issue. ID has no place in science. Unfortunately, there’s a lot of money and politicking involved in the issue. If enough people bullshit, loudly and frequently, other people start to listen and believe. That doesn’t make what’s being said not bullshit. Try an experiment. Come up with some outlandish lie. Something that’s possible, but highly improbable about you or that could have happened in the news. Start telling people. See how many check it out, how many believe it at face value, how many call your bullshit. You won’t gain a lot of trust this way, but you might discover something interesting.
