Homing Devices for Your Kids These days, panoptic vigilance is a much more practical matter, as the advent of kid-tracking technology for the consumer market shows. A company called Wherify Wireless in Redwood Shores, Calif., sells a satellite location device designed to be worn by young children. For $399 and a monthly service fee ranging from $25 to $50, parents can outfit their kids with a chunky plastic watch in ''cosmic purple'' or ''galactic blue'' that will transmit the wearer's location using signals from the Global Positioning System's network of satellites. Parents can retrieve the location on the Internet or by calling a Wherify operator.
Even Blind People Can Draw What has really shocked cognitive scientists, however, is that many blind artists seem to have the tricks of the Renaissance buried inside their brains. Foreshortening, vanishing points and other devices of modern pictorial realism -- techniques that artists in the Middle Ages lacked -- can be found in blind art.
'C.S.I.' Myth, The Smooth criminals can apparently train themselves to beat the polygraph machine -- which measures pulse and breathing rates, sweating and blood pressure -- by using Valium and obscure muscular acrobatics involving their sphincters.
Unexamined Life Is Worth Living, The In his recently published book, ''Strangers to Ourselves,'' Wilson argues that the real key to our behavior lies in a part of the brain known as the adaptive unconscious. Evolved perhaps before consciousness itself, it is the realm responsible for such indispensable cognitive skills as acquiring language, sizing up situations quickly, detecting signs of danger, sussing out relationships -- skills that everyone uses every day without even realizing it. Think of the adaptive unconscious as the generator in the basement that hums along unnoticed, but without which little could happen.

Living for Tomorrow | Metropolis Magazine | December 2002 Whether the project will succeed in persuading developers and builders to take on its means and methods is a big question. MIT's would not be the first project to be thwarted by industry recalcitrance. Even the government-backed, multibillion-dollar initiative of the 1970s, Operation Breakthrough--which set out to increase housing production and reduce costs with an engineered approach to building--failed to infiltrate what is essentially a craft-based industry. Bob Kuehn, a Massachusetts builder, welcomes MIT's initiative but remains skeptical about its applicability. "Frankly I don't see it," he says. "There are too many barriers from the way the craft unions are organized. It's hard to come in and say, 'This used to be carpentry, but now it's somebody else's work.' I can remember when we stopped using lumber and went to metal studs, and what a big fight that was."

Larson pulls no punches when it comes to depicting the industry: "It's fragmented, conservative, worried about lawsuits, resistant to change, and involves labor-intensive processes that no industry in the world would use."

Antidepressant-Induced Sexual Dysfunction Associated with Low Serum Free Testosterone SUMMARY

In the course of an evaluation for treatment of antidepressant induced sexual dysfunction (ASD) with a new agent, an unforeseen pattern emerged in the pre-treatment laboratory assessment. Free serum testosterone levels in both men and women study subjects were found to be below the normal ranges in 75 percent of subjects in this small study. There were no other consistent laboratory findings that could account for such a high percentage correlation. Further inquiries into the possible causes for decreased serum testosterone and its association with ASD seems warranted.


Antidepressant induced sexual dysfunction (ASD) is a well recognized complication of treatment for mood and anxiety disorders (Gitlin 1997). Recent discoveries have helped to provide effective remedies for this significant obstacle to patient compliance and successful treatment outcome (Cohen 1997, Gitlin 1997, Bartlik 1995). However, no remedy is 100% effective. In addition, there is no fully satisfactory theory that explains the physiologic mechanisms responsible for the varied aspects of sexual dysfunction observed (Sussman 1998). In the course of an evaluation of treatment for ASD in a community office based research setting, a striking pattern emerged in the laboratory screening protocol. Free testosterone levels were found to be subnormal in 15 of 20 patients. No other consistent laboratory value nor physical examination finding could account for this observation. Causes for reduced free testosterone and its effect on sexual function are discussed with implications for future research and treatment strategies.

Dental History Fluoride is a chemical found in many substances. In the human body, fluoride acts to prevent tooth decay by strengthening tooth enamel and inhibiting the growth of plaque-forming bacteria. After researchers discovered this characteristic of fluoride, fluoridation -the process of adding the fluoride to public water supplies-began.

It all started with Frederick S. McKay, a Colorado Springs, Colorado, dentist, in the early 1900s. McKay noticed that many of his patients had brown stains, called "mottled enamel," on their teeth. McKay set out to find the cause, helped by researcher Greene V. Black (1836-1915) of Northwestern University and other dentists. By 1916, Mc Kay believed the mottling was caused by something in the patients' drinking water. By 1928, he concluded that mottling was linked to reduced tooth decay.

Edge 59 The problem is that every time a student takes a course because he has to, he finds himself faced with a serious motivation problem. If you don't know why you need to know something it is difficult to learn it and what you learn won't stay in memory for long. If we don't use something, or at least see how we might use it, it is difficult to retain it. A course in calculus may well be useful for an economist, but since the actual course likely has very little to do with economics and the calculus that would eventually be used by the economist, the student will have trouble caring about or retaining what he learned. If he never uses what he learns, he'll forget it entirely.

Jan Prochazka, an important figure of the Prague Spring, came under heavy surveillance after the Russian invasion of 1968. At the time, he saw a good deal of another great opposition figure, Professor Vaclav Cerny, with whom he liked to drink and talk. All their conversations were secretly recorded, and I suspect the two friends knew it and didn't give a damn. But one day in 1970 or 1971, with the intent to discredit Prochazka, the police began to broadcast these conversations as a radio serial. For the police it was an audacious, unprecedented act. And, surprisingly, it nearly suceeded; instantly Prochazka was discredited: because in private, a person says all sorts of things, slurs friends, uses coarse language, acts silly, tells dirty jokes, repeats himself, makes a companion laugh by shocking him with outrageous talk, floats heretical ideas he'd never admit in public, and so forth. Of course, we all act like Prochazka, in private we bad-mouth our friends and use coarse language; that we act different in private than in public is everyone's most conspicuous experience, it is the very ground of the life of the individual; curiously, this obvious fact remains unconscious, unacknowledged, forever obscured by lyrical dreams of the transparent glass house, it is rarely understood to be the value one must defend beyond all others. Thus only gradually did people realize (though their rage was all the greater) that the real scandal was not Prochazk
Almost there: a commercially viable fuel cell
Berkeley Lab researchers have developed a solid oxide fuel cell (SOFC) that promises to generate electricity as cheaply as the most efficient gas turbine.
Their innovation, which paves the way for pollution-free power generators that serve neighborhoods and industrial sites, lies in replacing ceramic electrodes with stainless-steel-supported electrodes that are stronger, easier to manufacture, and, most importantly, cheaper. This latter advantage marks a turning point in the push to develop commercially viable fuel cells.

Questionaire for identifying possible sleep apnea Questionaire for identifying possible sleep apnea
Sleep Apnoea FAQ / Sleep Apnea FAQ People with sleep apnoea generally have the following symptoms:

* Loud, frequent snoring
The pattern of snoring is associated with episodes of silence that may last from 10 seconds to as long as a minute or more. The end of an apnoea episode is often associated with loud snores, gasps, moans, and mumblings. Not everyone who snores has apnoea, by any means, and not everyone with apnoea necessarily snores (though most do). This is probably the best and most obvious indicator.
* Your bedmate indicates that you periodically stop breathing during your sleep, or gasp for breath
* Excessive daytime sleepiness/fatigue:
Falling asleep when you don't intend to. This could be almost anytime you are sitting down, such as during a lecture, while watching TV, while sitting at a desk, and even while driving a car. Ask yourself, "Did I used to be able to (read, drive, watch TV) for longer periods of time without falling asleep?" If the answer is yes, you may have sleep apnoea or another sleep disorder. Even if you don't literally fall asleep, excessive fatigue (that is, you got plenty of sleep and you're still really tired) could be an indicator.
INSURANCE LEGISLATION FOR ENTERAL FORMULA Our son Jon who was diagnosed with Crohn’s disease at age 13 has been on Vivonex enteral feedings via a PEG since 1992. This has been a crucial element of his treatment which enabled him to achieve normal growth and development, and which still helps him maintain his active and productive life. Maintaining insurance coverage for this part of his therapy has been problematic for us, and we are concerned about his continued access to this aspect of his care as he transitions into independence.

When he was first started on NG feedings his primary insurance coverage was an HMO through his father’s employment. According to every document we had ever received from this HMO, any and all care that any of us might require would be provided as long as we had complied with their rules for arranging care through the primary care physician, obtaining appropriate referrals, etc. So we were shocked when the HMO adamantly denied coverage for either the Vivonex formula or any of the supplies associated with its infusion, stating flatly that this was "not a covered service". Nowhere in their plan description had they hinted that any necessary services were simply "not covered". Fortunately, I was also employed and Jon had secondary coverage through my employment at a hospital. One provision of this hospital’ s benefit contract was 80% reimbursement for employee purchases from the hospital’s own pharmacy. So for a number of years I continued to order the Vivonex where I worked. However, the fact that our HMO could get away with flatly refusing to cover something so obviously medically necessary as Jon’s enteral feedings continued to rankle. And, as it became increasingly obvious that Jon would continue to require these feedings indefinitely, we had to worry about what would happen when he was no longer eligible as my dependent for my employer’s insurance with its own peculiar loophole.

I didn’t know anyone else on home enteral nutrition. I put out a feeler through the Mutual Help Network column of the Crohn’s & Colitis Foundation magazine. I received only a few scattered responses from other patients, but their insurance experiences, like ours had been pretty negative. I felt more and more strongly that if insurance companies were not willing to voluntarily cover enteral feedings, there must be regulation or legislation from the appropriate government entity to protect these patients from what amounted to blatantly discriminatory treatment of their particular medical need. But where to begin such a process seemed a very daunting task without more patients or families to join in the petition.

The Rise of ``Worse is Better'' Now I want to argue that worse-is-better is better. C is a programming language designed for writing Unix, and it was designed using the New Jersey approach. C is therefore a language for which it is easy to write a decent compiler, and it requires the programmer to write text that is easy for the compiler to interpret. Some have called C a fancy assembly language. Both early Unix and C compilers had simple structures, are easy to port, require few machine resources to run, and provide about 50%--80% of what you want from an operating system and programming language.

Reuters Health Information (2002-11-06): Germ warfare nothing new, Tartar bioterror shows Germ warfare nothing new, Tartar bioterror shows

Last Updated: 2002-11-06 12:45:46 -0400 (Reuters Health)

By E. J. Mundell

NEW YORK (Reuters Health) - Imagine populations in the West terrified by the prospect of biological attack from enemies lurking deep within central Asia.

Sound familiar? For the inhabitants of Europe nearly 700 years ago, the threat of bioterrorism--in those days from Mongol hordes storming across Russia--was all too real. And historians say that in at least one incident, the "Tartars" succeeded in unleashing the bacterium responsible for the Black Death on a trapped and helpless citizenry.

In 1346 "the Mongol army hurled plague-infected cadavers into the besieged Crimean city of Caffa, thereby transmitting the disease to the inhabitants," writes Dr. Mark Wheelis, a microbiologist and expert on bioterrorism at the University of California, Davis. He believes the medieval attack could provide lessons on the magnitude of the bioterror threat facing the world today. - Bubonic plague suspected in NYC visitors - Nov. 7, 2002 NEW YORK (CNN) -- A New Mexico couple who traveled to New York have been hospitalized with what is believed to be the first case of bubonic plague in the city in a century, said health officials.

The couple arrived in the city last Friday and went to the hospital two days later with high fever and swollen lymph nodes. The man, 53, is in critical condition and on life support at a Manhattan hospital; his 47-year-old wife is in stable condition, said officials. Both are in isolation at the hospital.

Wednesday, November 06, 2002 rudy rucker revisited Your computer science textbook Software Engineering and Computer Games is coming out from Addison Wesley this fall. Are video games a good way to teach computer science?

IMHO, having students do computer games projects is absolutely the best possible way to teach programming, graphics, software engineering, object oriented programming, etc. I used to be into photography, and I managed to get hold of this very nice camera, a Leica M4. And I was constantly shooting pictures with it. And then I wanted another lens, and I went to a store that carried Leica stuff, and I found out that a lot of people were into collecting Leicas, like keeping them in glass cases. To me, a camera is for taking pictures. And a programming tool like Visual Studio or the JDK is for writing programs. Not for collecting different versions of, or for arguing about, or for comparing to other products. It's there to use. Writing a game is a nice big problem that makes you program a lot.

The Bogdanov Affair We all laughed when the physicist Alan Sokal wrote a deliberately silly paper entitled Transgressing the boundaries: towards a transformative hermeneutics of quantum gravity, and managed to get it accepted by a refereed journal of social and cultural studies, Social Text.

But around October 22nd, many of us began hearing rumors that two brothers managed to publish at least 4 meaningless papers in physics journals as a hoax - and even got Ph.D. degrees in physics from Bourgogne University on the basis of this work!

The rumor appears to have begun with an email from the physicist Max Niedermaier to the physicist Ted Newman, and it spread like wildfire. I received copies from many people, and soon there was a heated discussion of what this meant for the state of theoretical physics. Had the subject become so divorced from reality that not even the experts could recognize the difference between real work and a hoax?

Consumer Information: " Why can't the Toyota Prius and Honda Insight get a carpool lane sticker?"
While the hybrid vehicles currently offered in California are very
clean vehicles, they do fall short of the EVs and alternative fuel vehicles
in several key areas and are not eligible for single occupant HOV lane
use. Even when counting power plant emissions, ZEVs offer significant reductions over hybrids and these emission rates improve over time due to the fact that hybrids produce more emissions as they age. In addition, gasoline powered vehicles have large emissions contributions due to the "upstream" pollution of refineries and fuel distribution.
AlterNet: I Want My SUV Truth be told, most of even the largest SUVs have fuel economy standards nearly identical to a new Porsche 911 (about 20 mpg), a vehicle capable of carrying only two snotty people and a small suitcase. And according to the most recent government data, the SUV's contribution to our smog problem pales in comparison to role played by commercial diesels and aging, oil-burning passenger vehicles (gross polluters).

WebMD - Fish Oil Eases Depression
Oct. 18, 2002 -- It may sound fishy, but researchers say taking a daily fish-oil supplement may boost the effectiveness -- or even replace -- antidepressants for treating depression in some people.
Metafilter | Comments on 20344
The hardest thing about figuring out if someone is at risk for suicide is that depression doesn't always manifest as weepy, low self esteem, isolating, lack of enthusiasm. It often manifests as anger, hostility, risk-taking behavior; particularly in men and in people with Bi-Polar Disorder type II. Also, people will try to act as if everything is normal out of fear of being incarcerated in a psych facility indefinitely, or fear of being thought badly of by family, friends, and associates.

The other misconception is that suicide is always a methodical,well planned event. It can be an impulsive, heat of the moment act, too. I guess what I'm trying to say is that is quite possible that she didn't display any of the signs traditionally associated with suicidal behavior. You shouldn't beat yourself up over "not seeing the signs." Not every person who kills themselves sticks to the classic profile of suicidal behavior.
