Re:Something missing in the head
Speaking of a sense of proportion.... in the United States you're three times as likely to die from a shark attack (1 death per year on average) as you are from from the measles (1 death every 3 years on average from 387 reported measles cases per year).
To put that into further perspective, the U.S. averages 11 deaths from fireworks and 24 from train crashes per year. Death from a literal lightning strike is 141 times as common than dying from the measles in the United States.
So let's not overreact quite yet.
Yes, there are things that kill you other than measles. The difference is that measles is pretty easily preventable - people just have to get vaccinated.
The other issue with measles - and most of the "childhood diseases" - is that they have other complications besides death.
https://www.cdc.gov/measles/ab...
"About one child out of every 1,000 who get measles will develop encephalitis (swelling of the brain) that can lead to convulsions and can leave the child deaf or with intellectual disability."
"Subacute sclerosing panencephalitis (SSPE) is a very rare, but fatal disease of the central nervous system that results from a measles virus infection acquired earlier in life. SSPE generally develops 7 to 10 years after a person has measles, even though the person seems to have fully recovered from the illness. Since measles was eliminated in 2000, SSPE is rarely reported in the United States."
That last line is ironic.

Re:Yellow Journalism
I'm not sure where the "Yellow" came from [...]
In the late 19th century Pulitzer and Hearst were going at it hammer and tongs trying to outsell one another in the newspaper business. They ended up in a contest over who could come up with the most sensationalized headlines and copy to sell papers. One of the simplest going theories for the origin of the term in the use of yellow ink during this period of big, exaggerated headlines. There are, however, other theories as well.
Thanks for the history lesson. I thought it had something to do with Hearst; but couldn't remember what.

Re: yeah, and?
Quote from Reversible Computing: A Brief Introduction
Interestingly, in this long term view, taking optimal advantage of thermodynamically reversible techniques requires not just different electronics, but also changes to all higher levels in computing - different logic designs and CPU architectures; different programming languages and algorithms. The reason is that in the reversible approach, as in the laws of physics themselves, information is a conserved quantity - it cannot be destroyed, although it can be uncomputed by careful, deliberate design. If information is simply discarded, as occurs continually (and implicitly) at all levels in traditional computing, it inevitably becomes heat.
This suggests that the end goal is *not* actually a general computer you can program like any other CPU. Is Michael P. Frank just making shit up?

Re:No, He Can't Do That
I'm not sure that analysis is correct. The case you linked to (in the indystar) never went to court. To consider it differently, if you are at a town-hall meeting, and CODEPINK runs in and starts shouting, they can be arrested.
Yet I am sure, since there's a bit more law in this area then the example that I provided. If you pay me, I'll teach you. Otherwise, I've given you more than enough resources and keywords to figure it out in your own.
Obviously that isn't something the creators of the constitution had thought about when they wrote the amendment, and none of the prior judgements really address the point, so the Supreme Court ruling would be based entirely on the opinions of the members of the court.

Re: Sororities

The fun numbers are at the end:
Women: 3.36
Sorority: 3.41Men: 3.20
Fraternity: 3.18University average: 3.29
By being male, you lose 0.9 GPA, and by joining a frat, another 0.2, for a total of 0.11 loss.
By being female, you gain 0.7 GPA, and by joining a sorority, you gain 0.5 more, for a 0.12 gain overall.
Note that the effect of joining a sorority is greater than that of joining a fraternity.Interestingly, the fraternity with the highest GPA just got suspended for spitting on wounded veterans and trying to urinate on the flag at the beach. Interpret that as you will.

Re:Plenty of other creatures haven't "evolved"OK, so I took the time to look it up.
The oldest references that I can find to the age of the American alligator (Alligator mississippiensis) is the Florida Museum of Natural History, who are of the opinion that the morpological differences between Alligator olseni (White, 1942) and Alligator mississippiensis (Daudan, 1802) are insufficient to justify calling them separate species. By the rules of zoological nomenclature the senior synomym applies. Specimens ascribed to olseni (and therefore, if you accept the FLMNH position, to mississippiensis) date back to the early Miocene at 16-18 Myr, possibly the earliest Miocene at 22-23 Myr. If you don't accept the FLMNH synonymy, then the oldest known fossils of Alligator mississippiensis date to the Pliocene around 5 million years. http://www.flmnh.ufl.edu/vertp... http://www.flmnh.ufl.edu/vertp...

Re:Aerial or underground ?
No - it's not even a question. Bury the lines and you will remove a large number of causes for power outages.
My parents live in a neighborhood with buried power lines. Yeah, on average the power goes out less often. However, they've had a recent issue with the buried lines decaying after 30+ years underground. When that happens, it's a much longer, and more expensive repair.
The thing that bothers me is well meaning landowners planting trees near power lines. Personally, I blame schools that hand out saplings to children without proper education. Yeah, they look nice when they are small. They don't stay small. -

Re:What an assholeToo bad that geneticist disagree with you. That's one reason why the latest revision of the APA's DSM doesn't consider transsexuality as a mental disorder any more. And remember those 2D:4D digit ratio studies, the ones that indicated that something hormonal happened before birth that can influence both gender and sexual orientation? Well, scientists have been able to replicate the influence of sex hormones by manipulating sex hormone levels in utero
Cohn and Zheng, also members of the UF Genetics Institute, found that the developing digits of male and female mouse embryos are packed with receptors for sex hormones. By following the prenatal development of the limb buds of mice, which have a digit length ratio similar to humans, the scientists controlled the gene signaling effects of androgen — also known as testosterone — and estrogen.
Essentially, more androgen equated to a proportionally longer fourth digit. More estrogen resulted in a feminized appearance. The study uncovered how these hormonal signals govern the rate at which skeletal precursor cells divide, and showed that different finger bones have different levels of sensitivity to androgen and estrogen.
We know that the 2D:4D digit ratio shows a correlation to both sexual orientation and gender identity. So, now the influence (or lack thereof) has been tied to what happens before you're born. My 2D:4D digit ratio is female. Thank you for playing.

Makes sense.
Our sense of smell is the sense running at the lowest level. It's wired straight into the brain in the shortest path of any sense.
This is why the peanut butter smell test can help diagnose Alzheimer's disease. I would expect nontraumatic loss of smell to highly positively correlate with damage to the structures of the temporal lobe (amygdala, basal ganglia, etc). This is where memory lives (in all its forms).
Smell is a pretty raw sense, as opposed to say, vision, which is highly processed by many different cortical systems and areas. I would therefore expect it to yield the best raw cerebral status metadata.

The hot oil would whirl around faster in Jupiter's gravity. Difficult to predict by how much due to the viscosity of the cooking oil. I speculate it would travel about 60% faster (square root of 2.53), just like the most comfortable walking speed on Jupiter is 60% than on Earth. I say most comfortable because your legs work like a pendulum and the frequency of that is 60% higher. In lower and lower gravities walking becomes impractical because it is so slow -- you have to wait longer for your legs to complete a step. http://www.phys.ufl.edu/courses/phy3221/fall07/DanielDimAnalysisMost%20Comfortable%20Walking%20Speed.doc

Re:Clathrate gun hypothesis
You see... I willing to bet the last 650,000 years didn't see an oil spill in the Gulf of Mexico either.
You might lose that bet. A LOT of oil spills into the gulf every year naturally, and it wouldn't be surprising if there were a rupture after an earthquake that released a lot of oil at the same time.......at least once in the last 650,000 years.
First, the below is not to say that I accept the lack of evidence as a rebuttal of the "clathrate gun hypothesis"
Then let's evaluate the chances of me loosing the bet.
First at all - just to know what you should google for, the terminology one uses spills vs seepage. In this regards, a quote from here:
The Deepwater Horizon site releases 3 to 12 times the oil per day compared to that released by natural seeps across the entire Gulf of Mexico. [...]
Natural seeps are not constantly active; the volume of oil released can vary considerably throughout the day and from day to day. As a result, only a small area around the source is actually exposed to "fresh" non-degraded oil, which is its most toxic state.[...] Their research suggests that oil from natural seeps normally stays in the water for between ten hours to five days.[...]
A sudden, concentrated and massive pulse of oil from an event such as the Deepwater Horizon disaster presents a fundamentally more acute stress to marine and coastal systemsSeismicity in the Gulf of Mexico - just as an estimate for chances of major spills from earth-quakes.
Hmmm... I might loose the bet, as there might have been major earthquakes... but somehow I'm more afraid of the "human greed" as pushing the trigger of the potential "clathrate gun". You see, the presence of old inactive rift faults, with major causes for earthquakes being the redistribution of sediments... doesn't seem as a big danger of things going astray... not as probable as the human greed.

Re:Death With Dignity
Homo sapiens has had more impact on biodiversity than any other species. The Great Oxidation Event lasted hundreds of millions of years and, while we have no means of establishing a survey of taxa from that era, it was most likely the result of a very large number of species, and indeed is such a long period of time that many speciation events could readily have occurred. Further, the autotrophs that released the oxygen in the first place had no means of affecting many of the anaerobes that live deep underground—and we do.
Here are your citations for humanity's impact. Suffice it to say that many of them will still be noticeable in a few million years:
- Climate Change, Human Impacts, and the Resilience of Coral Reefs
- Consequences of changing biodiversity
- A continent transformed: Human impact on the natural vegetation of Australia, which went on for something like sixty million years before we screwed it up.
- Tropical forest recovery: legacies of human impact and natural disturbances
- The Future of Biodiversity, the abstract for which starts: "Recent extinction rates are 100 to 1000 times their pre-human levels in well-known, but taxonomically diverse groups from widely different environments. If all species currently deemed "threatened" become extinct in the next century, then future extinction rates will be 10 times recent rates. Some threatened species will survive the century, but many species not now threatened will succumb. Regions rich in species found only within them (endemics) dominate the global patterns of extinction."
- Urbanization, Biodiversity, and Conservation
- Biodiversity inventories, indicator taxa and effects of habitat modification in tropical forest (PDF)
I don't know why you then decided to compare humanity's effect on biodiversity to that of mass extinction events, but let me explain to you why they are completely different.
When an extinction event occurs, there is a single source of pressure that living organisms must accommodate, or at most a couple: the sky is darker, the air is colder, the atmosphere is now filled with water rather than ammonia, et cetera. Humans have not been exerting this kind of pressure at all. We systematically destroy ecosystems, replacing hundreds of species of plants and animals with just one or two (which are, naturally, attuned to depend on us feeding, fertilizing, irrigating, and sheltering them) and we poison the water, air and soil with thousands of chemicals and chemical cocktails (an issue which is now so bad it's affecting us.)
This is too much for evolution to handle. Especially due to chemical poisoning, many of the hardiest species most likely to survive a natural disaster have been snared by exotic and unexpected genetic vulnerabilities. DDT was found to act as a sex hormone in birds, for example, causing males to develop female genitalia. As a South African, I'm sure you're aware that it's still in use, combating Malaria, even though it has been banned in many countries.
We are whittling down biodiversity in ways that the Great Oxygen Catastrophe didn't. It selected one major branch of the tree, the organisms that depended on a reducing atmosphere, and marginalized them, creating room for the healthy and d

Bozeman, MD, FACEP, FAAEM (PDF of a slideshow presentation made at University of Florida), Study: Tasers are safe to use - Physorg, Independent studies could answer questions about Tasers. I can't seem to locate a published record of that particular study, but here is another paper by Dr Bozeman that compares Tasers to other methods of incapacitation: Medical Aspects of Less Lethal Weapons.
Your turn.

In general, students may transfer 60 credit hours from community colleges as part of the hours needed for their UF degrees, regardless of when these hours are earned, subject to university and college degree requirements.

Junior-/senior-level (courses numbered 3000-4000) course requirements for the major must be completed at UF or, with permission of the studentâ(TM)s UF college, at another baccalaureate degree-granting institution. At least 25 percent of semester credit hours must be earned through instruction at the University of Florida. -
Hardly Surprising
The content in Saudi Arabia's domestic mass media is under the control of the government, having to pass through censors before it makes it on air or in print. Furthermore, while the press is said to be privately owned, the editor-in-chief of each newspaper is appointed by the government.

Traditional media is already under government control. Thousands of people producing online media are less easy to control, so they're only handing out licenses to those individuals they approve of.
