Comment: Perverse Incentives (Score 1) 135

Most of the authors' analysis rings true, but Dr. Harold Varmus, in particular, contributed enormously to the perverse incentives he now complains about when, as NIH Director, he mandated "modular grants", in which scientists simply request grant support in multiples of $25,000 without the traditional detailed budget and without any salary data. Indeed, scientists were (and still are) expressly forbidden from including in their application any information on exactly how they proposed to spend the requested grant money or what they were paying themselves. The predictable response of the universities (and I speak here from first-hand experience) was to strongly encourage faculty to put larger portions of their salaries onto grants, and be rewarded with higher base salaries. Such policies were enthusiastically sold by department chairmen to upper-level administrators as a way of incentivizing faculty to acquire more grant support, while at the same time raising faculty salaries, all at zero net cost to the University. The fact that all this occurred at the same time as the doubling of the NIH budget only encouraged the process. Now the hard times are here again, money is tight, and support personnel are being let go, but faculty are not giving up their higher salaries and the universities aren't going back to paying faculty from university funds to do research, at least not without a fight.

When I arrived at Carnegie-Mellon University in 1968, all programs were running on a Univac 1108, soon to be replaced with a much more powerful IBM 360. In those days every science major learned to code in their freshman year. You would type your program onto punch cards, one instruction per card, then type your data onto cards, and dump into the submission box. Hours later you'd pick up your printout in your (physical) mailbox. Faster turnaround if you submitted at say 2AM. No security at all in those days, so occasionally your program cards would be stolen, if you hadn't duplicated it you'd have to start from scratch.

The opaque price structures of both Verizon and the cable companies show just how essential a regulated service is. If the telcos want to abandon POTS, then in return they ought to be required to offer comparable service on whatever system they propose to replace it with, and at the same price it was on POTS, a price that can never rise more than inflation. After all, electronics costs are dropping all the time, and they ought to be saving millions not having to maintain 2 separate systems anymore. Instead they seem to be offering exactly nothing in return. Where it's still available voice + DSL can be had for $50. Any hardwired replacement, cable or fiber, approaches $100, and so does wireless with a data cap comparable to DSL (150 GB/month). In my area, you can't even get internet without also taking voice. It's criminal. The other thing they need to do is to ban bundling and teaser rates. Mandate standard, transparent pricing: one price for the connection, then separate prices for internet, TV and voice. As it is, the pricing structure all but forces consumers to buy entertainment services if they want a connection at all.

These charter-school folks have a long-term agenda, and that is the conversion of public education from a public service to a fully privatized profit center, with the added perk of eliminating teachers unions as a political force. A key factor in achieving this is that wealth inequality has become so extreme that local governments no longer have the resources to educate the nation's children, but billionaires do. Can parents and boards of education afford to say "no" when, in the face of decaying buildings and teacher layoffs, big-time donors come offering modern, well-staffed facilities, with all the latest IT and other equipment, if only you let the donors do it their way? Once the public school system is reduced to being merely a dumping ground for the worst, most disruptive and unresponsive students, the donors won't have to be so generous, they'll be making handsome profits as the contractors in a privatized fee-for-service education system. It's just like the 1990s when deep-pocketed for-profit HMOs offered healthcare at below-market rates. Once all the nonprofit hospitals and insurers were driven out of business, the for-profits jacked up premiums at double-digit rates for decades. It was a brilliant strategy, and it's happening all over again, in education.

To me, the Times is well worth the 2 bucks a week I pay for it (with an .edu address). The articles are more comprehensive than any of the free news sites, and the ads are low-key. I feel news is something we should pay for, after all, someone has to pay all those reporters, editors, etc. It's become clear online ads aren't going to do it, and it shouldn't be governments paying them either. There are only going to be a few survivors in the online news game, but the Times might be one of them. They'll need millions of subscribers though, and last I heard they didn't even have a million yet.

Automotive grade lithium batteries are slowly falling in price but currently cost about $500 per kWh and can last perhaps 3000 charge-discharge cycles, so the cost to store and release one kWhr is about 16 cents, more than the total price of electricity in most of the US even at peak periods, but a good bit less than the retail price of electricity in Japan, about 32 cents. So in Japan it might actually make sense, depending of what the peak/off-peak differential is. But as suggested in the initial post, yes, is would make just as much sense to simply put some batteries in the basement and forget the cars. For that matter, you don't need lithium, lead batteries - cheaper but less durable - work out to about the same cost per kWh stored and released. But as lithium battery prices continue to fall, the day is not that far off when storing electricity from intermittent solar and wind sources in very large batteries will be economically feasible.

"[it] can run at an 80 percent efficiency when used to provide both heat and power." This makes no sense. If you count the heat produced, any combustible material can easily yield much better than 80 percent efficiency just by burning it. Condensing natural gas boilers, for example, routinely run at >95% efficiency. Of course, they're producing all heat and no electricity, but by the specified criteria, that's more efficient than the Cube. Straight % efficiency in producing electricity only, would be a much more useful number. I doubt that they're only counting electricity in the 80%, but it's ambiguous as written.

We are in fact increasing longevity and slowing down the aging process, but that only means an ever-longer period of helplessness preceding death. The most frightening statistic I've heard is that for every year of increased longevity that modern medicine has provided, only seven months is an increase in the time one is in good health. The other five months is an increase in the time during which you're still alive but have lost the ability to care for yourself. What's really needed is to minimize that period of dependence, in other words, delay the aging process while at the same time making it more sudden. Slowing it down is the worst thing you can do.

I've often taken notes on laptop at seminars and scientific meetings, and I've found it helps me concentrate on the talks. Taking notes on paper is distracting primarily because it requires constant glancing down at the paper. Further, I can type much faster than I can write. Rather than transcribing exactly what the speaker is saying, though, I find myself putting things in my own words, which keeps my attention from straying. But it's essential to be typing by touch and not looking down at the keyboard or the screen, which is as distracting as writing on paper. Typing errors, sometimes approaching one per word, can be corrected later, and in fact provide a convenient opportunity to review the material. If the study excluded surfers and included only touch-typists, I'm confident the laptop note-takers would do better.

The first stations will be built adjacent to Tesla's charging stations on the SF-to-LA route, and a swap will take no longer than filling a gas tank. From the article: "A battery pack swap will cost between $60 and $80, about the same as filling up a 15-gallon gas tank", Musk said. "Drivers who choose to swap must reclaim their original battery on their return trip or pay the difference in cost for the new pack.""

If the states really wanted to collect all that sales tax, all they would have to do is enforce current law (requiring residents to pay the tax themselves) and increase the penalties for evasion. Random audits would reveal massive infraction - supposedly less than 1% of taxpayers in states requiring it report any internet or other purchases where the vendor did not charge tax. But they won't do this, they're too scared of the backlash from voters. In short, they want somebody else to do the dirty work for them.
