Shift Work Dulls Brain Performance

SixFactor Re:Shift Work - Clarification (131 comments)

"Way lower production, too..."

That's kind of funny (and expected); I had the opposite experience at the plant. Night shift got things done, and done right! Might have had to do with a much smaller "uh-oh" crowd present in the wee hours.

I agree with you about how doing a meaningful study of this would be difficult. Maybe if the setting were say, in mainland China, which has a more compulsory (read: coercive) culture, then perhaps useful data could be obtained.... hmm....{Flame Proofing ON}

Shift Work Dulls Brain Performance

SixFactor Shift Work - Clarification (131 comments)

"Shift work" covers a wide range of jobs, from repetitive tasks (as in a factory) to technical support (as in a call center). TFA is really more interested in the disruption of the circadian rhythm because of those types of jobs. What would be interesting is if there was some differentiation in that study according to the types of jobs. Would working at a call center result in a different sort of degradation than, say, assembly? The former engages the brain (according to my firstborn, who seems to enjoy it), while the latter, well, I don't know if I could handle something like that for too long.

And having worked night shifts during our refueling (nuclear plant) outages, I can say that it was never dull, with all manner of problems to solve and people to deal with. There's definitely a nice camaraderie that develops on the night shift, so the term "anti-social" didn't quite apply.

Japan's Annual Nuclear Drill Highlights Problems

SixFactor Re:Good job. (43 comments)

I second. Drills are the way to identify and correct flaws, as well as to identify areas for improvement. It is unfortunate that it took a one-two punch to turn around Japan's nuclear culture, but hopefully they come out stronger, as we had following the Three Mile Island Unit 2 event in 1979. Here in the U.S., even now, emergency drills at nuclear power plants continue to optimize emergency processes, and to test a plant's (including and especially its staff's) response to a significant adverse event. The typical drill postulates a series of malfunctions that inevitably lead to a radiation release, which then triggers an evacuation. This latter part is designed to exercise local and state resources as well.

After Fukushima, the paradigm got turned a bit on its head: instead of a nuclear plant event causing the emergency, it's a natural calamity that degrades and destroys infrastructure that could lead to a radiation release. As a result, the lessons learned prompted at least one order, which requires all U.S. plants to be ready for events that are beyond their current design bases. In other words, if your plant was designed for a Category 3 hurricane, be ready to handle one that's much more devastating. As you might expect, this is no small expense, but the U.S utilities have committed to making the preparations, and you can find descriptions of these on the NRC website.

Kids Score 40 Percent Higher When They Get Paid For Grades

SixFactor Re:weird (716 comments)

Amen to that. I've told my kids that their parents have jobs: I am the breadwinner, while mom manages the household. It is therefore their job to attend school. I get performance reviews at work (while mom is of course, exempt from such :D). It is therefore important for them to do well at school, and grades, like it or not, reflect that progress.

Seems to me that the financial incentive has two functions: while it can clearly be a motivator (that likely promotes only short-term and shallow learning; but that's another discussion), it is also an indicator of how parents value (or de-value) education.

Secret US List of Civil Nuclear Sites Released

SixFactor Re:"for civilian use" (167 comments)

SDM,

I admire your effort and appreciate the apparent pro-nuclear stance. But please check out the NRC Fact Sheet on TMI Unit 2 (Unit 1 is doing just fine, thanks) for more precise details on the cause and sequence of events for the accident. You'll find some useful facts that will correct some of your misconceptions about the contributing factors and root causes of the event.

In my opinion, the most dominant root cause was inadequate operator training. The stuck-open primary valve (PORV) was misdiagnosed, with a faulty valve position indicator contributing to the misdiagnosis. Every operator action taken downstream of that led to the circus surrounding the event. It did not do to create emergency operating guidance on the fly. I contend that if there was no operator interference with the Emergency Core Cooling System(s) (yes, there are several), the core would have remained intact for some time (days).

BTW, SDM stands for Shutdown Margin - at least in the civilian side of the nuke industry. :D

Scientists Create Easier Way To Embed Objects Into Video

SixFactor Re:A few points of note: (236 comments)

"1. Initially from a computer forensics pov, it would be trivial to detect if a video has been altered, however i think with further improvements in the embedding technology where the actual advert piece is better rendered to take into account surrounding lighting conditions it might become more difficult, however not impossible to detect intentional modifications"

If I'd points, I'd mod you insightful - and I appreciate the understated tone of the statement. One implied (er, embedded) concern here is the legal standing of video evidence, say from ATM or other security surveillance cameras. A new and probably more intense layer of forensics will have to be added to validate such evidence. I foresee a mess (but I hope I'm wrong).

Car? Plane? It's Both and Legal

SixFactor SixFactor writes  |  more than 4 years ago

SixFactor (1052912) writes "At long last, a street-legal plane (or airworthy car), has been approved by the Federal Aviation Administration. Because of its size, weight, and lack of usual auto safety features, it's got decent gas mileage on the road. Only requires 20 hours of flying time to get a license, and a third of a mile to get airborne. At just under $200k, it's a bit expensive, but there are definitely some early adopters."

Nuclear Reactor Turbine Replacement

SixFactor SixFactor writes  |  more than 6 years ago

SixFactor (1052912) writes "This stopped my channel surfing cold: an unprecedented glimpse of an infrequent evolution — the replacement of a Boiling Water Reactor's high pressure turbine. The "Nuclear Turbine" episode of National Geographic Channel's "World's Toughest Fixes" is a well-executed and detailed documentary on how a turbine replacement proceeds at a US BWR. It also provides an excellent overview of various aspects of plant operations including security, radiation protection (more precisely, contamination control), training, and perhaps even more importantly, the nuclear industry's safety culture. Plant personnel were shown as professional, but not devoid of a sense of humor. The discussion regarding high level waste was a bit clipped and did not include the planned Yucca Mountain repository, but then again it was not the show's central subject. And my one nerdy gripe was with their slightly erroneous computer animation of the steam flowpath into the high pressure turbine.

I think this may the first time after 9/11 that a TV crew has been allowed within the protected and radiation control areas of an operating US nuclear power station. Everyone will find this episode highly entertaining and informative. It will be re-broadcast a few more times later this month, but is also available among the show's other episodes here. Enjoy."

Life from Artificial DNA?

SixFactor SixFactor writes  |  about 7 years ago

SixFactor (1052912) writes "Bioengineering proves itself again a field of significant breakthroughs. From a Washington Post article, researchers in Maryland are about to conjure life from completely artificial DNA. This is a rich article that covers profound angles like, life as an operating system, energy, genetically manipulated food, patent law, and most interestingly, raises shades of Jurassic Park:

Many scientists say the threat [referring to "bio-error"] has been overblown. Venter notes that his synthetic genomes are spiked with special genes that make the microbes dependent on a rare nutrient not available in nature.

And we all know what happened to those critters with amphibio-dino genes, don't we? So, just because we can, should we? "

Vista Service Pack 1: Light Dawns on Marblehead

SixFactor SixFactor writes  |  about 7 years ago

SixFactor (1052912) writes "From InformationWeek, some hopeful news for troubled Vista users. On the one hand, it could be argued that Microsoft is being responsive to its users' needs. On the other hand, "responsive" in Redmond appears to involve significant (v — >c) time dilation.

The money quote from the article:

Microsoft marketing VP Michael Sievert told InformationWeek in March that Vista was "high quality right out of the gate" and that the company would likely dribble out small updates as required via its Windows Update service.

I do not know if 300 or more changes constitute a dribble, but Service Pack 1 is at least a step in the right direction. But I think I'll wait for SP2 before replacing XP on my Windows machines."

SixFactor (1052912) writes "An idea to use plankton to fight climate change, is getting serious consideration. Plankton blooms, induced by fertilizing desolate patches of ocean with iron, are being tested for their capacity to absorb carbon dioxide from the atmosphere, and transport the greenhouse gas to ocean depths. If the tests yield immediate and measurable results, the effort could be a viable implementation of carbon offsets. However, if overdone, imagine getting to a "tipping point," where the concern is no longer global warming, but the opposite. One thing is notably absent from the article: there is no requirement for an Environmental Impact Statement. But I do foresee happier balleen whales."

SixFactor (1052912) writes "From here, it was revealed that software used for training at Palo Verde Nuclear Generating Station was illegally downloaded by a former PVNGS engineer while he was visiting in Iran. He allegedly took the software from the software vendor, which is based in Maryland. The software contained details of the site, and how it operates. There are a couple of obvious possibilities on why he did this: to provide an example of the training used at US plants, to further the nascent Iranian nuclear program; or, for more nefarious purposes. What is troubling is that this person's ability to access the software remained viable after his employment at the site."

SixFactor (1052912) writes "From KING5 in Tacoma, a woman's house got trashed when someone put up an ad on Craigslist stating that the house's contents were "free," inviting all and sundry to come and help themselves. A cruel act, and Craigslist's policy divulges information on ad posters only if a warrant or subpoena is issued. This makes immediate investigation of the scam difficult.

Not having used Craigslist, it seems to me that there has to be a way of providing some level of bona fides in setting up (and responding to) ads, such as a credit card number, to provide accountability and perhaps traceability. This could perhaps deter the malicious prankster, maybe even the criminal."

His remains will be in good company, as Gordon "Gordo" Cooper's ashes will also be along for the ride. Gordon Cooper was one of the pioneer Mercury astronauts, and was featured in the movie "The Right Stuff." The two will reach the final frontier in a SpaceLoft XL rocket.

SixFactor (1052912) writes "As described here, Israel has developed an infantry bot called VIPeR (Versatile, Intelligent and Portable Robot). It can pack an Uzi, pistol, or grenade launcher, among other hardware. An interesting feature is its Galileo wheel system, which can morph from a simple wheel to a track system. So far, the human will always be in the loop, and the article offers a key contrast with the US approach:

"Unlike the ambitious US plan to develop and deploy highly autonomous combat robots as part of the FCS [Future Combat Systems] program, the Israeli approach is more pragmatic, considering the contributions of such autonomously navigated vehicles in rather limited, mission-specific tasks. These will initially include perimeter security and border patrols and could later be enhanced to specific roles in force protection."

At his Most Coherent

SixFactor SixFactor writes  |  more than 7 years ago I found this in a transcript, and decided it was sufficiently exceptional to be saved as my first journal entry. Excerpted from an April 24, 2007 interview with Charlie Rose (grammaticals and all):

Charlie Rose:

What's the lessons [sic] of all this for you, the war in Iraq and what it means for the future? And what have you learned that you think would like to put in a note on the desk of [your] successor?

President George W. Bush:

I've learned that in order to make profound decisions that affect the future of the country, you must have a set of principles that are firmly etched in your soul, that you can't make good decisions if you chase the latest focus group or opinion poll, that you've got to believe a principle such as freedom is universal, and there is no kind of moral relativity when it comes to that subject, as far as I'm concerned. People deserve and desire to be free. And that history has taught us democracies don't war, so forms of government matter in terms of finding peace. But you have to believe principles in order to put up with all the noise, all the pressure, all the flattery and criticism that happens in Washington DC. That's one of the primary lessons I've learned as the president.


While he's definitely not a Ronald Reagan (see the balance of the transcript), this statement (which he probably memorized) is a lesson any presidential candidate should learn, hopefully before the elections, and definitely before taking the oath of office.
