Comment Re:Disbar. (Score 4, Interesting) 124

I remember reading a case, I think it was in Reader's Digest, where a Lawyer was 'touring' through small towns, then suing their main streets(more precisely, all the businesses on said main street) for ADA violations, doing much the same as presented in this article.

Despite being in a wheelchair, I believe he did end up being disbarred from the practice. What happened to him is that he did it enough that the towns found each other, formed a group, and basically caught the dude lying. As a lawyer representing himself, what could be considered 'mistakes' added up to him not doing 'due diligence'.

For example, he sued a hardware store for not having a wheelchair ramp. Yet said hardware store had had such a ramp for decades before he came by. Once this was noticed, they started going through his claims, collated from the various lawsuits, and started noting up discrepancies. For example, him suing a store for not being accessible inside - when the store had been closed when he supposedly visited due to illness by the owner/operator. Basically, they figured out that he stayed in the hotel for a couple days, then sued everybody on the street, without having actually attempted to patronize their business. A number of businesses actually had accommodations for him - he would have simply had to ask, which is very much allowed under the ADA.

Comment Re:Assets valuation? (Score 1) 335

This is the problem with placing monetary valuation on any object or service; value is in the eye of the beholder, and that includes the value of money itself.

That's why everything ends up being estimates, but with something like a wheelbarrow there's a number of stores you can get a wheelbarrow in, so you end up with a standard price for wheelbarrows, which is the general range where the person who needs a wheelbarrow can count on being able to buy one, and where a person with a wheelbarrow can count on selling it.

So you might 'value' your wheelbarrow at $100, but if the price of wheelbarrows actually traded is around $50, that indicates that you're not looking to sell. If a dude values his at $20, but can sell it at $50, he's probably going to adjust his valuation to ~$50 and sell it at that price.

So the guy with 50 wheelbarrows values them at ~$2500 and puts that on his value sheet. He might value them a bit more, but if he went to liquidate or had to replace the wheelbarrows(theft, natural disaster, accident), that's what they'd be worth.

The idea is that with a large company, unless you have systematic errors, it should be 'pretty' correct in most companies, despite the individual value of things like 'name brand', IP, and such being hard to estimate correctly.

Comment Re:Does not understand the market, obviously. (Score 2) 335

Right. It's been rare in recent decades for even individual companies to sell for less than their asset value, for precisely the reason you mention: that nearly any functioning business is worth more than the sum of its assets.

Part of the deal with this, I believe, is that if a company has a Q-value of less than one it's a prime indication that it would be worth more broken up, and is thus a prime target for corporate sharks to come in and liquidate it, dissolving the company or selling the remnants to suckers after having sucked the worth out of the company.

A q-value of less than 1 is an indication of a company that's NOT efficient with it's assets.

Comment Re:No self driving trains? (Score 2) 393

I think that depends on the subway. Property taxes already go towards paying for the road in front of most houses, for example, because there's not enough traffic for gasoline taxes(for example) to pay for the upkeep.

In a city where the roads can't keep up, paying at least for the subway transitway makes some sense. The extra transport capacity helps bring customers and employees to the work site. To put it another way, in properly situated sites adjusting things for the extra car traffic would be even more expensive.

Another factor you might not be considering is the marginal cost per passenger is quite small for rail(most forms of transit, really). You can run into a situation where if the trains were full, you wouldn't need to subsidize them even at low fare levels, yet at high fare levels you won't get enough passengers, so the rate of subsidization actually remains pretty constant. But by setting fairs low you actually move more people that way.

In a lot of cases, our rail travel sucks because there's just not enough of it. With enough investment - straightening routes allowing higher speeds, to actually useful destinations, we could make it a lot more prevalent, and safer/cheaper/more environmentally friendly to everybody.

The idea being that you're a lot more likely to take a 200mph train that can actually get you to work faster than driving. And because there's so many people like you, the train's reasonably full and thus profitable.

Comment Re:This is a ridiculous way to make concrete. (Score 4, Informative) 94

Concrete longevity has a LOT to do with preparation and maintenance.

For example tree roots - proper subsurface preparation, which isn't normally done for sidewalks, will result in roots not extending far under the concrete, and even if they do penetrate somewhat, not growing large enough to crack the concrete. Failing that, routine maintenance with certain products will kill the roots before they get too large, but leave the rest of the tree unaffected.

As for your questions -
1. It will probably only fix any given crack spot once.
2. 99% of the fixes will be practically microscopic in nature.
3. At the depths we're looking at, restoring a barrier is a bigger deal than being structural.
4. Most of the time the very cracking releases the stress that caused the crack, then water gets in and freezes, widening it. This keeps the water out(after the bacteria do their job).

If you think that everyone that has a hand in reviewing or providing comments at the request of the author on a paper should be listed as sources or authors you don't know anything about how scientific papers work.

If you think this then you misunderstood what I said. Last paper I wrote went through about a dozen different people.

However, if they received information, and not just the usual constructive criticism, then the person should be cited. Merely having males review the paper doesn't mean that a male viewpoint has been considered in said paper, which is what I was trying to get at.

He didn't say that they, must be of a higher quality. He said that it's a possibility that shouldn't be ignored. You can't just assume it's not true.

Finishing up a 300 level statistics course at the moment, and this fits right in with it.

You have the 'null hypothesis', which is what you're trying to reject/not reject. So 'Women's papers are just as good as the Men's' is, crudely speaking, a valid null hypothesis. You do all your math and you either reject it(p=.95), or fail to reject it(insufficient evidence say that they aren't). Other options include Men's papers being better, or women's being better.

And the crazy thing is, they did consult with male colleagues before publishing.

If they did so and didn't cite such in their paper, then they're bad at writing papers. If they did cite such, then he's a bad reviewer.

Then there's my usual answer - you generally get things like this when two assholes meet. So they might of written what he saw as a biased paper and reacted poorly.

Let's be honest. It can often be a bit of a stretch to see how any particular CS class or concept impacts society in a way that seems meaningful.

Same can be said for most engineering work. Anyways, what I was trying to get at is that making it look 'more socially meaningful' in order to attract women means that it would, at least theoretically, attract more men as well, because we care about that stuff as well.

I just had this /exact/ conversation with my wife. She said that the idea presented in this op-Ed is condescending (speaking a civil engineer herself). She said "what, women engineers just aren't getting enough hugs?"

Indeed. I found the op's bit '"An experience here at the University of California, Berkeley, where I teach, suggests that if the content of the work itself is made more societally meaningful, women will enroll in droves," writes Nilsson.' to be incredibly sexist in a number of ways.
1. Implies that women are more interested in 'socially meaningful' work
2. Implies, by correlation, that men aren't.
3. That the current engineering work isn't 'socially meaningful',
Oh, and news lady, Berkeley isn't 'normal'.

Oh, and it's not her fault, but remember that at this point men are highly outnumbered at most universities by women. They're the minority, not women.
