So, remember the S&L Crisis of the late 1980s? I do. It was a direct result of the deregulation pushed by Reagan which resulted in unwise real estate lending. In the end, it cost American taxpayers something like $160 billion to clean up the mess (that’s about $270 billion in today’s money). Notable names associated with this debacle include John McCain and Neil Bush.
Well, guess what happened this morning?
WASHINGTON — U.S. federal regulators outlined their takeover of Fannie Mae and Freddie Mac Sunday morning, including control of the firms by their regulator and a Treasury Department purchase of the firms’ senior preferred stock.
The plan, outlined jointly by the Treasury Department and Federal Housing Finance Agency, also includes a plan for the Treasury to purchase mortgage-backed securities from the firms in the open market, and a lending facility through the Treasury from its general fund held at the Federal Reserve Bank of New York.
OK, this is basically S&L Crisis, Part II: Revenge of the Greedoids. You, and me, and every other US taxpayer are now on the hook for trillions of dollars of bailout money. Why? Deregulation and unwise real estate lending.
Yes, that is a gross oversimplification. But it is essentially true, and even one of the men responsible said so last year. Between them, Fannie Mae and Freddie Mac control something like half of the mortgages in the US, to the tune of about $12 trillion. Now, not all of those mortgages are going to go ‘bad’. But it’ll probably take trillions of dollars to clean this mess up.
Why do it? Well, the argument is that this is just too large a component of the US economy to allow things to spiral down. So the government has stepped in to secure ‘preferred stock’ in these two entities – the kind of stock held by other banks and foreign governments – in order to cushion the impact of the ongoing credit crisis.
But there is a problem in doing this. From the Wikipedia entry on the 2007 Subprime Mortgage Crisis:
A taxpayer-funded government bailout related to mortgages during the Savings and Loan crisis may have created a moral hazard and acted as encouragement to lenders to make similar higher risk loans.[68]Additionally, there is debate among economists regarding the effect of the Community Reinvestment Act, with detractors claiming it encourages lending to uncreditworthy consumers[69] [70] and defenders claiming a thirty year history of lending without increased risk.[71][72][73]Some have argued that, despite attempts by various U.S. states to prevent the growth of a secondary market in repackaged predatory loans, the Treasury Department‘s Office of the Comptroller of the Currency, at the insistence of national banks, struck down such attempts as violations of Federal banking laws.[74]
Yeah, you got that right: the feds *stopped* individual states from enacting legislation which would have limited the damage.
Your tax dollars at work. In the service of the big national banks who wanted to operate under the easier rules on the Federal level.
And now, we’re going to wind up with the tab for the bulk of the mess. And, in doing so, will once again establish that we’re not willing to let big businesses suffer the consequences of their errors in judgment (in this case the monetization of bundled subprime mortgages). I hold the current administration predominantly responsible for this debacle, just as I held the Reagan administration predominantly responsible for the failure to regulate the banking industry in the 1980s, but both political parties share some of the blame for refusing to stand up to the special interests who wanted to be insulated from their bad business practices.
I believe in the free market. But intelligent regulation has to temper the excesses of business. We learned that lesson in the 1930s. It looks like we’re going to have to learn it again.

Do you own a fire extinguisher? Why?
Do you own a fire extinguisher? Why? Are you expecting a fire? Or do you have some sort of left-over juvenile desire to play fireman, a private macho image of rushing into a burning building to save a child? Don’t you know that improperly used, a fire extinguisher can be dangerous to yourself and others? And there have been “studies” done that show people who own fire extinguishers are actually more careless with fire risks, thinking that they’ll always be able to resort to their fire extinguisher to solve the problem. Besides, firefighters are always right there when you need them, and can put out any fire for you, so there’s no point in having your own fire extinguisher.
How about an emergency first-aid kit? Do you have one of those? Why? Are you expecting to injure yourself? Or do you have some sort of left-over juvenile desire to play doctor, a private macho image of saving someone from bleeding to death with an improvised tourniquet? Don’t you know that improperly used, medical supplies and equipment can be dangerous to yourself and others? And there have been “studies” done that show people who own first-aid kits are actually more careless in general, thinking that they’ll always be able to resort to their medical supplies to repair any injury they sustain. Besides, Emergency Medical Technicians or doctors are always right there when you need them, and can instantly patch you up if you get injured, so there’s no point in having your own first-aid kit.
Are these responses to being prepared absurd? Yeah. But they are exactly the sorts of responses I get when people find out I have a permit for carrying a concealed weapon, and generally carry a pistol whenever and wherever I can legally do so. And my experience is not at all unusual – most gun owners encounter the same sort of reaction from non-gun owners. We’re asked if we’re expecting to have a shoot-out in the supermarket. We’re asked if we have some childish fantasy about playing cops & robbers. We’re told that if we want to play with guns and shoot people that we should join the military. We’re confronted with facts that guns are inherently dangerous to ourselves and others, and that “studies” have shown that owning a gun makes it more likely that we will behave in such a fashion as to need to resort to using one to get us out of a dangerous situation. And besides, there’s always a cop around when you need one, just to protect you, so there’s no need to have a weapon for self defense.
Are there gun owners who think that carrying a weapon makes them invincible, and they therefore go around with a chip on their shoulder, putting themselves in dangerous situations thinking that they can always whip out their pistol and escape? Yeah, probably. But that is no more the typical mindset of a gun owner than is the notion that someone who owns a fire extinguisher is going to be careless with fire risks. Are guns inherently dangerous, and if used improperly present a threat to the owner and anyone else in the vicinity? Definitely. Which is why anyone who carries a weapon has a responsibility (usually mandated by law in the state which issued their concealed carry permit) to know how to safely handle and use a firearm, how to safely store it, and when it can be legally used in defense of self or another. And are there gun owners who think that they’re some kind of auxiliary police force, ready to jump in and right any criminal wrong they see being committed? Yup. In fact, a lot of people who legally carry a firearm do so precisely because there are situations where intervening could save the life of a loved one, a friend or even a stranger. But that doesn’t mean that they are wanna-be cops. Rather, they’re just trying to help contribute to their own safety and the safety of others. The police, firefighters and EMTs can’t be everywhere. We do have a responsibility to protect ourselves, to make prudent preparations in the event of an unexpected turn of events. That means having a fire extinguisher handy in case of a fire. It means having a first aid kit, and knowing some basic medical skills for dealing with an emergency. And for me it means having a gun available as a tool for self protection. Your level of comfort with how you are prepared for what situations may well be different, but that does not mean that my decision, and the decision of millions of other Americans, to legally and safely carry a concealed weapon is wrong or paranoid.

I’ve written previously about the emergence of consciousness and the role that the biochemical stew in our heads plays in awareness and cognition. But let’s get a little more basic in our analysis. Let’s consider fire. No, not the slow fire of chemical reactions in our bodies, but actual burning of wood, and the role that it may have played in the development of human intelligence.
* * * * * * *
The Greek myth of Prometheus bringing the holy fire of Zeus to mankind, and thereby enabling civilization, has usually been understood as being an explanation of the role which technology plays in human development. After all, fire allows humans to control our environment, from living in colder climates to clearing land for farming to metallurgy. And, of course, to cook food, making a wider range of nutrients available.
But what if fire made human thought itself possible?
Cooking and Cognition: How Humans Got So Smart
After two tremendous growth spurts — one in size, followed by an even more important one in cognitive ability — the human brain is now a lot like a teenage boy.
It consumes huge amounts of calories, is rather temperamental and, when harnessed just right, exhibits incredible prowess. The brain’s roaring metabolism, possibly stimulated by early man’s invention of cooking, may be the main factor behind our most critical cognitive leap, new research suggests.
OK, that article is a little light on actual information. So I went to check the research paper. It’s a bit thick, but the basic idea was to study the rise of human cognition via two methods:
In this study, we attempted to identify molecular mechanisms involved in the evolution of human-specific cognitive abilities by combining biological data from two research directions: evolutionary and medical. Firstly, we identify the molecular changes that took place on the human evolutionary lineage, presumably due to positive selection. Secondly, we consider molecular changes observed in schizophrenia, a psychiatric disorder believed to affect such human cognitive functions as the capacity for complex social relations and language [6–12]. Combining the two datasets, we test the following prediction: if a cognitive disorder, such as schizophrenia, affects recently evolved biological processes underlying human-specific cognitive abilities, we anticipate finding a significant overlap between the recent evolutionary and the pathological changes. Furthermore, if such significant overlap is observed, the overlapping biological processes may provide insights into molecular changes important for the evolution and maintenance of human-specific cognitive abilities.
Got that? First, you determine the differences due to evolution (specifically as seen in DNA/mRNA divergence between us and chimpanzees), then you see where the brains of people who have schizophrenia are different from ‘normal’ brains. That can give you some indications of how cognition works, since schizophrenia is known to primarily impact cognition.
What did the researchers find?
In order to select human-specific evolutionary changes, we used the published list of 22 biological processes showing evidence of positive selection in terms of their mRNA expression levels in brain during recent human evolution [13]. Next, we tested whether expression of genes contained in these functional categories is altered in schizophrenia to a greater extent than expected by chance. To do this, we ranked 16,815 genes expressed in brain in order of probability of differential expression in schizophrenia, using data from a meta-analysis of 105 individuals profiled on 4 different microarray platforms in 6 independent studies [14]. We found that 6 of the 22 positively selected biological processes are significantly enriched in genes differentially expressed in schizophrenia (Wilcoxon rank sum test, p < 0.03, false discovery rate (FDR) = 11%), while only 0.7 would be expected to show such an enrichment by chance (Figure 1; Table S2 in Additional data file 1; Materials and methods). Strikingly, all six of these biological processes are related to energy metabolism. This is highly unexpected, given that there were only 7 biological processes containing genes involved in energy metabolism among the 22 positively selected categories (Figure 1; Table S2 in Additional data file 1). The mRNA expression changes observed in schizophrenia appear to be distributed approximately equally in respect to the direction of change, pointing towards a general dysregulation of these processes in the disease rather than a coordinated change (Table S3 in Additional data file 1).
Simply put: it’s metabolism. The brain eats up a lot of energy, about 20% of all the energy you take in as food. That’s a lot – for chimps the number is about 13%, and for other vertebrates it runs 2 – 8%. The conclusion:
In this study we find a disproportionately large overlap between processes that have changed during human evolution and biological processes affected in schizophrenia. Genes relating to energy metabolism are particularly implicated for both the evolution and maintenance of human-specific cognitive abilities.
Using 1H NMR spectroscopy, we find evidence that metabolites significantly altered in schizophrenia have changed more on the human lineage than those that are unaltered. Furthermore, genes related to the significantly altered metabolites show greater sequence and mRNA expression divergence between humans and chimpanzees, as well as indications of positive selection in humans, compared to genes related to the unaltered metabolites.
Taken together, these findings indicate that changes in human brain metabolism may have been an important step in the evolution of human cognitive abilities. Our results are consistent with the theory that schizophrenia is a costly by-product of human brain evolution [11,37].
When did this take place? From the LiveScience article first cited:
The extra calories may not have come from more food, but rather from the emergence of pre-historic “Iron Chefs;” the first hearths also arose about 200,000 years ago.
In most animals, the gut needs a lot of energy to grind out nourishment from food sources. But cooking, by breaking down fibers and making nutrients more readily available, is a way of processing food outside the body. Eating (mostly) cooked meals would have lessened the energy needs of our digestion systems, Khaitovich explained, thereby freeing up calories for our brains.
* * * * * * *
In Communion of Dreams, I posit the use of “auggies” – drugs designed to maximize the utilization of neurotransmitters in the brain. When combined with increased sensory information thanks to technology, an artificial kind of synesthesia occures, allowing for insights (artistic, cognitive) otherwise beyond human ability. But it is a cheat – you ‘burn up’ the available neurotransmitters quickly, accelerating brain function, but are left then less capable for a period of days after as the body replenishes. This is by and large a metabolic function – the same way an athlete can burn up energy stored in muscles in one brief period, but then needs time to recover.
I wrote this with an instinctive understanding of the mechanism involved – we’ve all experienced something akin to this phenomenon of pushing ourselves mentally for a short period, being tired and less able to think clearly afterwards. It’s a bit surprising to find that it may have literally been the same mechanism which lead to the rise of human intelligence to begin with.
And as for the alien artifact on Titan, which causes a similar phenomenon? Just coincidence that Prometheus was one of the Titans in Greek mythology.
No, really – just coincidence.

There’s a line from a Babylon 5 episode (I’m a big fan of the series) which has always stuck with me. Several characters are discussing the political situation on Earth following the imposition of martial law. One character says that people love it – crime is down, things are calm, peaceful.
“Yeah, the peace of the gun,” replies another character.
And that, my friends, is what we have today, here in the US. Specifically, in one small city in Arkansas:
HELENA-WEST HELENA, Ark. – Officers armed with military rifles have been stopping and questioning passers-by in a neighborhood plagued by violence that’s been under a 24-hour curfew for a week.
On Tuesday, the Helena-West Helena City Council voted 9-0 to allow police to expand that program into any area of the city, despite a warning from a lawyer with the American Civil Liberties Union of Arkansas that the police stops were unconstitutional.
Police Chief Fred Fielder said the patrols have netted 32 arrests since they began last week in a 10-block neighborhood in this small town on the banks of the Mississippi River long troubled by poverty. The council said those living in the city want the random shootings and drug-fueled violence to stop, no matter what the cost.
“Now if somebody wants to sue us, they have an option to sue, but I’m fairly certain that a judge will see it the way the way the citizens see it here,” Mayor James Valley said. “The citizens deserve peace, that some infringement on constitutional rights is OK and we have not violated anything as far as the Constitution.”
From another source:
Controversial Curfew in Helena-West Helena
Mayor James Valley has given residents in one high-crime neighborhood two choices…. go home or go to jail.
Valley’s issued a mandatory curfew for Second Street and the surrounding blocks — a place he considers to be a “hot spot” for crime. The curfew applies to anyone of any age at any time of day.
* * *
“This turf belongs to taxpaying citizens, not to hustlers and drug dealers….We are going to pop them in the head,” Mayor Valley said.
* * *
The mayor only has the power to issue a 48 hour curfew – so he says when this one expires, he’ll issue another one, and another one.
Predictably, the ACLU is taking a rather dim view of this:
The ACLU has written a letter to Helena-West Helena Mayor James Valley protesting the curfew he imposed on a portion of the city. The mayor says he’s received the letter, but believes it’s intentions are misplaced.
* * *
Mayor James Valley says no constitutional rights have been violated — he says they’re doing what’s needed to clean up the streets.
No doubt. And he’s willing to be reasonable:
Helena-West Helena Curfew Changes
Leaders in Helena-West Helena have come up with a new plan after criticism by the ACLU of the mayor’s recent curfew on a particular part of town.
This past weekend, Mayor James Valley issued a mandatory curfew for Second Street and the surrounding blocks — a place he considers to be a “hot spot” for crime.
* * *
Valley’s curfew will remain in place for all minors, but adults will be allowed out if they can answer questions about their need to be outside their homes.
See, like I said – he’s being perfectly reasonable about this. You can leave your house. If you can explain to authorities why you need to do so.
How could anyone possibly object to this?
*sigh*
This is nothing more or less than the peace of the gun. This is the abrogation of civil liberties as a solution for incompetent governance. Of course people like it – let things get bad enough that they fear for their lives more than they value their liberties, and you can get people to do almost anything. Mayor Valley is just applying the same logic as he applied in mid July when he, well, here’s the news report:
Mayor Orders Dogs Released Into Forest
You’ve heard it before…..Arkansas animal shelters struggling to take care of unwanted dogs and cats. One mayor has decided the best way to fix the problem in his town is to set the animals free.
KARK visited the Helena-West Helena animal shelter back in January. Conditions were dirty and animals were in poor health.
Thursday, KARK learned the town’s mayor James Valley has taken the unconventional approach of releasing the animals into the wild. In a press release, the mayor says “we fed and watered them and took them to the St. Francis National Forest.”
Yeah, he just turned them loose.
Like I said, incompetence. Let things get so bad, and then you can take absurd steps.
Like imposing martial law.
Is this just a trial run for other cities? Other levels of government? Because you can be damned sure that there are power-hungry people watching this situation very closely, and drawing their own conclusions. If a small-town mayor can get away with it, why not a large city mayor? Or a governor? Or a president?

I mentioned in passing last week that I was working on all my care-giving posts for a book. Here’s a bit more about that project, as it is tentatively shaping up.
Sometime last year, when I cross-posted one of those entries on Daily Kos, I discovered that there was someone else there who was in pretty much the exact same situation: caring for a beloved mother-in-law. For a variety of reasons, it is fairly unusual to find a man caring for a mother-in-law with dementia. We didn’t strike up what I would call a friendship, since both of us were preoccupied with the tasks at hand, but we did develop something of a kinship, commenting back and forth in one another’s diaries on that site. Our paths diverged – he and his wife eventually needed to get his mother-in-law into a care facility, whereas my wife and I were able to keep Martha Sr home until the end. But the parallels were made all the more striking by those slight differences. In the end, his “Mumsie” passed away about six weeks before Martha Sr died.
Recently this fellow and I picked up the thread of our occasional conversation once again. And discovered that both of us, independently, had been thinking of writing up a book about the experience of care giving. It didn’t take long before we realized that together we could produce a more comprehensive book, and a lot more easily, drawing on our individual experiences to show similarities and different choices. A few quick emails sorted out the pertinent details – basic structure of the book, that all proceeds from it will go to the Alzheimer’s Association (or them and other related organizations), some thoughts on publishing and promotion – and we were off and running.
For now, I’ll just identify him by his screen name: GreyHawk. By way of introduction, check out this excellent post of his at ePluribus Media, where he very neatly explains the *why* of our decision to write this book:
Special thanks to Jim Downey for the supplying the links to the video and to his blog, and just for being him; my wife and I took comfort from the fact that we were not alone in our situation, and that we knew at least one other couple who were going through a very similar experience to our own.
That’s it right there. Millions of Americans are facing this situation today, and millions more will in coming years as the baby-boomer generation ages. I’m not a scientist who can help find a cure to the diseases of age-related dementia. I’m not wealthy and able to make a significant difference in funding such research. But I can perhaps help others to understand the experience. GreyHawk and I are going to try, anyway. I know that my wife and I found comfort in knowing that we were not alone in this. So did he and his wife. If we can share that with others, and make their experience a little more understandable, a little easier, then that will be a worthy thing.
Wish us luck.

Yesterday was an anniversary. Here are some stunning pictures related to it. There have been movies made about it. And movies about what it meant. Or what it could lead to. And, of course, there are a whole bunch of books on related subjects. I’ve talked about the threat it presents. Lore about it has widely influenced popular culture. And it is still topical.

Here in the Midwest there is a real and significant problem with meth – to the point of paranoia on the part of both the population and government. This has led to laws restricting access to certain precursor drugs and chemicals, reports of environmental damage (meth labs tend to produce some really nasty chemical contamination), and the development of special task forces of local, state and federal police agencies to target meth production and distribution. It is the War on (Some) Drugs on steroids.
So it is fairly easy to see how something like this can happen:
Town Finds Drug Agent Is Really an Impostor
GERALD, Mo. — Like so many rural communities in the country’s middle, this tiny town had wrestled for years with the woes of methamphetamine. Then, several months ago, a federal agent showed up.
Busts began. Houses were ransacked. People, in handcuffs on their front lawns, named names. To some, like Mayor Otis Schulte, who considers the county around Gerald, population 1,171, “a meth capital of the United States,” the drug scourge seemed to be fading at last.
* * *
But after a reporter for the local weekly newspaper made a few calls about that claim, Gerald’s anti-drug campaign abruptly unraveled after less than five months. Sergeant Bill, it turned out, was no federal agent, but Bill A. Jakob, an unemployed former trucking company owner, a former security guard, a former wedding-performing minister, a former small-town cop from 23 miles down the road.
Ah, yes, that is a bit of a problem.
Read the whole piece, and you’ll likely be astonished that this guy was able to pull off this con job for so long. He had no documentation. He claimed that he didn’t need a warrant to enter people’s homes and businesses. He got by on cop-like swagger, a black T-shirt that said “POLICE”, a cop-wannabe car, and a short haircut.
Oh, and on the fact that the local police and government wanted him to succeed for their own purposes.
See, this is the thing. Pesky things like due process and respecting the civil rights of people slows down drug investigations. Or terror investigations. This can frustrate cops at about every level, who see a problem and honestly want to fix it. Along comes someone who says that he has the solution, and it is easy to believe him.
This is what the Wars on Drugs and Terror have brought: a willingness to trust authority at the cost of civil liberties. A willingness to cut corners to ‘meet the threat’. A perception that we’re in a crisis, and only by extraordinary means can we survive.
It starts by recognizing a problem. Then, because identifying and targeting a problem brings with it increased budget and power for the agency/department tasked with dealing with the problem, there is a tendency to inflate the problem, convince the public that the problem is growing, or deeper than initially thought. Things spiral, slowly at first, then with increasing speed. Unchecked, this positive-feedback loop takes on a life of its own, until it culminates in stupidity and horror.
This is the basic mechanism of what happened with the Inquisition. With the Salem Witch Trials. With the Red Scare(s). And now with the Wars on Drugs and Terror.
Think that I am over simplying? Here’s what Bill Jakob’s attorney, one Joel Schwartz, said about how his client got into this mess:
“It was an innocent evolution, where he helped with one minor thing, then one more on top of that, and all of the sudden, everyone thought he was a federal agent,” Mr. Schwartz said. “I’m not saying this was legal or lawful. But look, they were very, very effective while he was present. I don’t think Gerald is having the drug problem they were having. I’ve heard from some residents who were thrilled that he was there.”
That right there explains why and how these things happen. The way to stop them is well known: legal protection and due process. Those mechanisms were developed slowly over the centuries, with notable culminations in Magna Carta, our own Constitution, and the Universal Declaration of Human Rights. We ignore those protections at our peril.

. . . Darths & Droids previously, and particularly want to point to today’s strip. Why? Because of the commentary:
You can tell inexperienced roleplayers from experienced ones quite easily. Put them in a room that might contain traps or lurking monsters.
The inexperienced players will check behind the furniture, under the rugs, around the walls, etc, etc. The experienced players will check the ceiling. All the worst things are concealed on the ceiling. Really experienced players will have a 10-foot pole handy, specifically to poke and prod the ceiling, just to make sure it doesn’t have any lurking monsters, collapsing sections, more lurking monsters, cunningly concealed deathtraps, even more lurking monsters, rusty spikes that might drop on you if you so much as breathe, and, of course, yet more lurking monsters.
And you can tell veteran adventurers in most fantasy worlds by the way they keep glancing up every few seconds.
Or veteran veterans, for that matter. Or anyone who pays attention to the surroundings. It’s called ‘situational awareness.’

Happily, Shuttle Discovery made it home safe and sound on Saturday, as scheduled, in spite of misgivings I expressed in my last post and in comments. But losing pieces of the shuttle (or any space vehicle) is always a concern, as discussed extensively by James Oberg in this item for MSNBC:
Why NASA watches out for true UFOs
Astronauts don’t keep mum about potentially life-threatening objectsHOUSTON – Friday’s brief orbital anxiety about threats from an unidentified object seen out the window of space shuttle Discovery underscore why NASA has always been interested in what can justifiably be called UFOs.
* * *
The reason is life-and-death. Since Mercury days, NASA engineers have realized that visual sightings of anomalies can sometimes provide clues to the functioning — or malfunctioning — of the spaceships that contain their precious astronauts. White dots outside the window could be spray from a propellant leak, or ice particles, flaking insulation, worked-loose fasteners (as in this latest case) or inadvertently released tools or components.
Whatever the objects might be, they pose a threat of coming back in contact with the spacecraft, potentially causing damage to delicate instruments, thermal tiles, windows or solar cells, or fouling rotating or hinged mechanisms. So Mission Control needs to find out about them right away in order to determine that they are not hazardous.
Oberg knows his shit, so take a few moments and read the whole thing.
As I’ve mentioned previously, we know that space travel is dangerous, and there is very little doubt that we will see more deaths. But there’s no reason not to learn from our mistakes, and to make things safer as we can.
