Children today hear so much praise that they've decoded its real meaning. We're making a mistake in thinking that we can manipulate them without recognizing that manipulation is at hand. So, the research is clear that children only under the age of seven take praise at face value and after that period of time, they learn the pattern. Kids who are praised a lot are the kids who teachers and parents are worried about.Kids become obsessed with looking good, not actually doing good. In the classroom
they tend to not want to take academic risks. And the worst consequence is that they make this conclusion: I should be getting by on my natural gifts, therefore, to show other kids I'm working hard, would be to broadcast that I'm not naturally smart. When, in fact, in real life you can't get anywhere without not just some intelligence, but also a lot effort and persistence.I can personally identify with that situation. I remember in graduate school struggling to grasp the calculus of economics, all the while trying not to let on to the truth. Failure shouldn't be ignored, but instead be recognized as a reality of living life.

Surprising as this may seem in the 21st century, your daughter’s strategy is not unusual. Evidence on speed-dating gathered by the economists Michèle Belot and Marco Francesconi shows that women are attracted by rich men, while men focus more on a woman’s physical appearance. Lena Edlund, another economist, has found that in the areas of her native Sweden where the wealthiest men live, women of prime marriageable age are over-represented.So this girl shouldn't just sit back and hope for missionary dating.
However, your daughter is only 15; for Edlund, “prime marriageable age” is 25-44. Your daughter is either going to have to get her hooks into this chap unusually early, or she is going to have to keep him on the boil for another decade – a lot of nail-painting.
Not only is she concentrating her investments into a single asset by abandoning her education, but she may even be making her main goal harder to achieve. Belot and Francesconi discovered that a strong social trend towards “assortative mating” means that although educated, high-achieving men are not interested in marrying a rich woman, they do like educated high-achieving women, rather than shallow girls with shiny nails.
Your daughter should learn to work hard and look good at the same time. Not only will it advance her immediate goals, it will also – sadly – stand her in good stead for the rest of her life.

From its inception, in 1892, the Pledge has been a slavish ritual of devotion to the state, wholly inappropriate for a free people. It was written by Francis Bellamy, a Christian Socialist pushed out of his post as a Baptist minister for delivering pulpit-pounding sermons on such topics as "Jesus the Socialist." Bellamy was devoted to the ideas of his more-famous cousin Edward Bellamy, author of the 1888 utopian novel Looking Backward. Looking Backward describes the future United States as a regimented worker's paradise where everyone has equal incomes, and men are drafted into the country's "industrial army" at the age of 21, serving in the jobs assigned them by the state.

Nationwide, 49% of fatal crashes happen at night, with a fatality rate per mile of travel about three times as high as daytime hours.Probably a combination of fatigue and alcohol. The fewest deaths
happened early in the morning, between 4 a.m. and 5 a.m. Those hours see significantly less traffic--only 9% of the average amount during peak hours.Surprisingly:
Mid-week days like Tuesday and Wednesday also pose the lowest number of fatalities, both averaging fewer drivers
fatalities actually drop across the nation during days with high amounts of snow, both because more people stay at home and because they tend to drive slower under inclement weatherI guess the best time to get groceries is at 4am on a Tuesday during a snow storm.

1) Extraction Costs: There are three ways for the government to get money. All have adverse effects on citizens:
- taxes: any government spending is taken from consumer spending (not even counting the costs of getting it= bureaucracy & accountants)
- borrowing: there is a finite amount of money to be loaned and any money loans to the government (through bonds) is money not invested in private industries (through stocks)
- printing money: leads to inflation (essentially a tax) and too much can lead to disaster (Zimbabwe)
3) Negative Multiplier Cost: Sometimes government spending is directly harmful. For example many regulatory agencies have small budgets, but impose huge costs on the private sector. I see this in the time I spend meeting government requirements for teachers. Not to say all regulations are bad, but undoubtedly regulation decreases output per dollar.
4) Behavioral Subsidy Cost: Many government programs encourage undesirable decisions. Welfare encourages encourages leisure over work. Home loan subsidies encourages consumer debt. Unemployment insurance encourages, well unemployment. Because wealth is determined by productivity, these policies shrink the economic pie.
5) Behavior Penalty Cost: This is the flip side of the last one. Government not only encourages bad behaviors, but it discourages good ones. Although tariffs are historically low, there are still laws that limit American citizens from buying the products that they want. Even cash for clunkers, which I discussed earlier, encouraged the purchase of new cars (within a certain time limit making saving for the purchase difficult) and will in the long run increase the cost of used cars (mostly purchased by the poor).
6) Market Distortion Cost: Government interference blinds consumers to real prices. For example in health care, also discussed earlier, because of government subsidies and the encouragement of employer provided insurance, consumers rarely pay the full price for care and in turn purchase too much. The same is probably true for education.
7) Inefficiency Cost: The industries that the government directly runs (Post Office, education, etc) could be run by private industries more efficiently. This is probably where the heart of the debate lies. Exactly how inefficient government run businesses are is hard to measure.
8) Stagnation Cost: Lack of "what would have been" in innovation. Without competition and a motive for profit, government run businesses have no incentive to improve. When I can get a banana from Costa Rica for less than it costs to send a letter to my neighbor, you know something is wrong.
However, do not think that I don't want government to do anything. I want it do to less sure, but I still need it to do the one thing that no business can do, enforce and protect property rights. The limited amount of the things I would like my government to do can be traced back to property rights. Here's what I mean:
- federal, state, and local military protects my life, liberty, and property
- protection under the law from violent crimes against my life, liberty and property
- enforcement of contracts on behalf of my life, liberty and property

Zombies are a popular figure in pop culture/entertainment and they are usually portrayed as being brought about through an outbreak or epidemic. Consequently, we model a zombie attack, using biological assumptions based on popular zombie movies. We introduce a basic model for zombie infection, determine equilibria and their stability, and illustrate the outcome with numerical solutions. We then refine the model to introduce a latent period of zombification, whereby humans are infected, but not infectious, before becoming undead. We then modify the model to include the effects of possible quarantine or a cure. Finally, we examine the impact of regular, impulsive reductions in the number of zombies and derive conditions under which eradication can occur. We show that only quick, aggressive attacks can stave off the doomsday scenario: the collapse of society as zombies overtake us all.So to summarize: an outbreak will be disastrous, unless there is a quick, well planned attack. So keep your shotgun close and I'll see you in the designated safe zone (mine is the nearest Super Walmart).

Being a Hefner Girlfriend was a specialised job, not to be confused with being a Playboy Playmate. In fact, Girlfriends were not allowed to become Playmates because Hef had found that they tended to flee the Mansion as soon as they collected their $25,000 Playmate cheque. Girlfriends were given their own bedroom, an allowance of $1,000 a week in cash, a new car, free dental and medical treatment, almost limitless clothes, hairdos, make-up and facials and all the cosmetic surgery they could wish for – Izabella reckons Hef shelled out $70,000 a year on breast implants.I would not have imagined it would be so, well professional. Like say, the oldest profession?
And then, of course, there was the sex – though surprisingly little of it according to Izabella. She reckons she had “less than 15 intimate minutes” with Hef in her two-and-a-half years at the Mansion – “I may as well have lived in a convent.” His main Girlfriend, Holly, shared his bedroom and presumably took care of his quotidian sexual needs – but Wednesdays and Fridays were Sex Nights when all the Girlfriends were expected to be on bedroom duty – though it was up to them whether they participated.I mean this to empower, not to degrade: how is this not prostitution?

Extraversion:Extraversion should be no surprise. I didn't really get Agreeableness, after all I love people. But then I remembered how little I liked group work and how I am always trying to figure out what people are "actually thinking". My low score on Conscientiousness is part of the reason why I started this blog. I have a goal of learning, but it is hard for me to get motivated to read. So I use my Extraversion and desire to teach people as motivation to organize my thoughts. As for Neuroticism, well if you've met me I'm pretty laid back. Openess also threw me for a loop at first. Then I remembered my recent trip to D.C. I loved going to see the Washington Improv Theater, but was quickly bored at the American History Museum (and I teach US History). I guess it depends on the cultural experience.
This trait reflects preference for, and behavior in, social situations. People high in extraversion are energetic and seek out the company of others. Low scorers (introverts) tend to be more quiet and reserved. Compared to other people who have taken this test, your score on this dimension (40) is relatively high.
This trait reflects how we tend to interact with others. People high in agreeableness tend to be trusting, friendly and cooperative. Low scorers tend to be more aggressive and less cooperative. Compared to other people who have taken this test, your score on this dimension (19) is relatively low.
This trait reflects how organized and persistent we are in pursuing our goals. High scorers are methodical, well organized and dutiful. Low scorers are less careful, less focused and more likely to be distracted from tasks. Compared to other people who have taken this test, your score on this dimension (21) is relatively low.
This trait reflects the tendency to experience negative thoughts and feelings. High scorers are prone to insecurity and emotional distress. Low scorers tend to be more relaxed, less emotional and less prone to distress. Compared to other people who have taken this test, your score on this dimension (11) is relatively low.
This trait reflects 'open-mindedness' and interest in culture. High scorers tend to be imaginative, creative, and to seek out cultural and educational experiences. Low scorers are more down-to-earth, less interested in art and more practical in nature. Compared to other people who have taken this test, your score on this dimension (24) is about average.

1) First, we need to understand the purpose of insurance. Whether it's health insurance, car insurance, or life insurance, the purpose of these are to pool risk as a safety net to pay for catastrophic events. The hope is that you never need to use them, but if you do, your family isn't bankrupted by a single event. Health insurance does not exist so I can get a $100 discount on eye glasses. It exists to so I can get a $100,000 cancer treatment. This seems to work in the car insurance industry. Sure they don't give me a discount on oil changes, but they do repair my car if someone damages it. One reason health insurance isn't like car insurance is the over 2,000 government mandates that add between 20-50$ to the cost of premiums. If consumers bore the full burden of non-catastrophic care, they would be less susceptible to the moral hazards of health care (another example with some teeth).
- 26% of the uninsured are eligible for some public coverage
- 21% of the uninsured are immigrants
- 20% of the uninsured have family incomes greater than $75,000 (more than me)
- 40% of the uninsured are young
- more regulation would increase costs and lead to less people with insurance
- to it's going to be very expensive and we don't have a lot of extra government funds
- the amazing, but currently unknown improvements in health care that would be developed for profit (most medical advances come from America's "broken" system)

So Funny I’m Jealous I Didn’t Say ItSubmit your own and you'll get an email you when they post it.
“What is he trying to do with that outfit?” Sarah asked Roy. Roy was deep in whiskey and clever as a fifth grade joke. The two of them were making fun of people.
“He’s trying out for an ugly competition,” Roy said and knew it was horrible.
“Dude looks like a virus with pants,” Sarah said. “Dude looks like a STD in a sports jacket!”
And, in the bathroom, Roy wrote it down on toilet paper. A STD in a sports jacket. He would use that later, in front of Sarah, by accident, and they’d stop being friends.

Some of the nation's biggest advertisers are distancing themselves from Fox News host Glenn Beck after he called President Obama a racist during a July 28 broadcast. Geico has pulled its ads from Fox News Channel's "The Glenn Beck Program." Lawyers.com, which is owned by LexisNexis, also has vowed not to advertise during the programThis is some proof that 24 hour news stations, no matter how bad they get, are still subject to market forces. If you want better news, demand it.

Forget about the dangers of increased driving and increased consumer debt, what frustrates me most is that there is a simpler, more efficient solution. Even though I commute 1 hour and 1/2 a day to work, I support increasing the gas tax a way to improve emissions, traffic and safety. It is more efficient (demand for gas is fairly inelastic), more equitable, and it's simpler (compared to a 4 month program that ran out of money in a week).
This programs exists not because politicians are irrational, but because voters are. As a teacher, I think voter education is the solution. Too bad my AP Econ class got cut in the slimming budget.

Then I heard about Monotizing Emma:
The year is 2013 and boutique investment bank Thackeray Walsh is arranging the first-ever securitization of smart teenagers.Nothing like the insanely convoluted securities that brought the global economy to its knees in 2008-2009, this bond is backed by something far more valuable than sub-prime mortgages or toxic assets.It’s backed by an A-list pool of adolescents pledging their future earnings. They get money now in return for a share of their subsequent income.Should of copyrighted it when I had the chance. Well this just a play, surely this can't exist in real life. Think again:
Students and alumni connect through UniThrive’s online community. Alumni search for students they want to lend to. Alumni pledge as much or as little money as they are willing. At 0% interest, these loans represent the best offering in the student loan market. Students form lasting relationships with their alumni lenders. Alumni can put a face to their contribution. Students pay back the loans after graduation.So it's a non-profit now, but there's no reason this same idea can't work with positive interest rates. But who would want to invest in students? How about me? Not just because I'm some delusional free marketeer, but because I'm a teacher. Who has better information on these investments than educators. Heck, this could even be a form of incentive pay for teachers:
What if teachers were paid based on the future income their students make. For example, student A grows up to make 100k a year. We look at the records and find the 20 teachers that taught student A and compensate them based on that. Compensation could be based on number of months spent with student.

At graduation, you walk off the campus toting the armor of self-confidence that comes from being told you are now "an educated adult." Self-confidence is extremely important.
Perhaps at some point it doesn't matter what actually happens during those four years; if the song-and-dance is elaborate enough, you will be convinced that education happened, and you will carry intellectual self-confidence with you into the world.
Does this phenomenon sound familiar?
If you want your headache to go away, it doesn't matter if you take real Advil or just something that looks and tastes like Advil -- the outcome is the same. The Placebo effect works. Why doesn't the same hold true for education?
In his new book, which I review here, Tyler Cowen writes:
Placebo effects can be very powerful and many supposedly effective medicines do not in fact outperform the placebo. The sorry truth is that no one has compared modern education to a placebo. What if we just gave people lots of face-to-face contact and told them they were being educated?
He reluctantly provides the terrifying conclusion: Maybe that's what current methods of education already consist of.

one of the most dramatic issues facing Generation X is infertility. No generation of women has had more trouble with fertility than this generation, who received the terrible baby boomer advice, "Wait. You have time. Focus on your career first."When I tell people my wife and I are thinking about kids in the next couple of years I rarely get a positive reaction. I'm not saying kids are for everyone, but if you want them, timing is something to think about:
There is plenty of evidence to show that the quality of your eggs takes a nose dive at age 35. And about 20 percent of pregnancies end in miscarriage, which means you have almost a 50 percent chance of having to go through three pregnancies to have two children. And it's recommended that you breast feed, which decreases your ability to get pregnant, at least while you're breast feeding. So be realistic: You can't count on getting pregnant three times in three years. You can't control fertility. Waiting until your midthirties to start a family, if you want to carry the babies yourself, is a risky endeavor. Which means, of course, you probably want to find a partner by the time you're 30.I've been surprised that so many of my married and unmarried peers have no imminent plans for children. This worries me for two reasons, societal problems and personal benefits. With most of the industrialized world under replacement and the rest of the world industrializing I see underpopulation as a future problem. However my main fear is people not realizing the personal benefits for having kids (or selfish reasons as stated by Bryan Caplan). Although children probably have a short term (20 years) negative effect on happiness for parents, the long term benefits are most likely positive. A 2003 Gallup study finds that 2/3 of childless people over 40 wish they had kids. I bet people with children don't regret their decisions that much.
If you don't want children then don't feel pressured into having them. People who don't want to have children know their own preferences much better than I do. However, if you do want children, especially multiple children, there is a time table. Careers can happen when you're 50, children cannot. And remember there are ways to make the hardships of parenting less hard. Finally, let me say that I cannot imagine the heartbreak of struggling to have children. It is because of those stories that I want to encourage those of us that can and want to, to have kids.

Predictable financial crises do not occur because it is profitable for private businesses to act on any information that may lead to a financial crises. Whether it's recognizing there is a surplus of housing or that borrowers and lenders are overburdened, the lack of information is what caused today's problems. Governments can remove the uncertainty they bring and economists can improve their ability to predict market crises, but then again if they did prevent anything you would never notice.

- It is scientifically nonsensical: There is no reason to square a person's height or ignore waist size.
- It makes no allowance for the relative proportions of bone, muscle and fat in the body.

- Insurance companies sometimes charge higher premiums for people with a high BMI. Among such people are all those fit individuals with good bone and muscle and little fat, who will live long, healthy lives.

1) The average years in retirement has gone from 0 in 1950 to 13.5 in 2005.
2) Time spent with their kids has been increasing since the mid-90's. This may be partially responsible for increasing IQ about 3 points per decade for the past century.
3) Americans spent over 20% of their disposable income on food in the 1930s and 1940s. Now we spend just 9.6%.
4) Large scale war may be over.
5) The US economy has never been so competitive. Meaning large companies have never had so little power.

Being a humanities or a social science major has a statistically significant negative effect on religiosity -- measured by either religious attendance and how important students consider the importance of religion in their lives. The impact appears to be strongest in the social sciences.Not all have a negative effect:
Students in education and business show an increase in religiosity over their time at college.As a Social Studies Education major at Clemson University, a school with above average religious attendance, I noticed this difference within the departments. I wonder if it's the old divide between what explains human behavior, science or scripture. I've never understood that debate since I think both are valuable.
