  • Much of the time spent discussing "ideas" in a business context is actually time spent slowly maneuvering large groups of managers into a compatible mind-space so that they can work together effectively - the results of the discussion in terms of ideas is worth nothing, whereas the result in terms of bonding, organizing, and motivating can be very valuable.

  • awesome - It seems what people want is a satisfying story about their place in the universe. Since characters are the most important elements of a story, the main “place” that matters to people is their social place – who they relate to and how. People feel they understand their place when they have a story saying how they can relate well to important social entities. Central to any social relation is whether the related person supports or opposes you in your conflicts. In fact, it seems enough to give your life meaning to just know who are your main natural allies and enemies among the important actors around, and what you can do to keep your allies supporting you, to give you high enough status.

  • And it seemed to be remarkably effective: a 2007 clinical study funded by Shaw’s company and conducted by the independent SGS Laboratories found the device prevented germs from being transferred to catheters nearly 100 percent of the time. Given these facts, you might expect that hospitals would be lining up to buy Shaw’s product. But that is not the case, even though his company is offering to match whatever price medical facilities are paying for their current, infection-prone IV catheter syringes. In fact, since the device hit the market two years ago, Retractable has sold fewer than 20,000 units, mostly to one New York hospital. Often, the company’s sales team can’t even get in the door to show their wares to purchasing agents. “The product does exactly what it is supposed to do,” Shaw says. “But it has one fatal flaw. Right there at the bottom of the handle it says Retractable Technologies.”
  • Our kids are all at that age and so its a regular family joke in the car ride home that the first to fall asleep gets a prize.  It sometimes even works.   But someone will fall asleep first, and once that happens the contest is over.  The other two have no incentives.  Also, in the first-to-fall game, each child has an incentive to keep the others awake. Not good for the parents. (And this second problem persists even if you add runner-up prizes.) So the new game in town is last-to-sleep gets a prize.  You would think that this keeps them up too long but it actually has some nice properties. Optimal play in this game has each child pretending to sleep, thereby tricking the others into thinking they can fall asleep and be the last. So there’s lots of quiet even before they fall asleep.  And there’s no better way to get a tired kid to fall asleep than to have him sit still, as if sleeping, in a quiet car.
  • In reality, people who are critically ill almost always look critically ill. It's not subtle. If you are in a lot of pain, or vomiting uncontrollably, or suddenly unable to move half of your body – by all means, come in. We don't expect or want people to diagnose themselves or their families. If it feels like an emergency, let us take a look at you. But if your sick child is feeling well enough to grab every toy in the toy bin and hurl it across the room, the chance they have anything that won't wait until their PCP can see them on Monday is between small and nonexistent. And if your symptoms would have led your mother to send you to bed and made you soup when you were six, it's probably safe to send yourself to bed when you're forty. And if you show up at the ED instead, I'm not going to run a battery of tests to figure out why you have a sore throat and a fever. I'm going to send you out on your mother's plan, the only difference being the terrifying bill that will follow after.
  • On a recent Wednesday morning, some Post editors were frustrated that the primary election results weren't garnering many hits -- despite the fact that John McCain had just won his party's nomination and Lisa Murkowski was on the verge of losing hers. What was hot, the traffic directors said, was Elin Nordegren telling People that her life had been "hell" since her husband's sex scandal, a photo of an alligator in the Chicago River, and a video posted on Gawker of a British woman throwing a feral cat into a dumpster.

  • In the past few years, Watts--a network-theory scientist who recently took a sabbatical from Columbia University and is now working for Yahoo --has performed a series of controversial, barn-burning experiments challenging the whole Influentials thesis. He has analyzed email patterns and found that highly connected people are not, in fact, crucial social hubs. He has written computer models of rumor spreading and found that your average slob is just as likely as a well-connected person to start a huge new trend. And last year, Watts demonstrated that even the breakout success of a hot new pop band might be nearly random. Any attempt to engineer success through Influentials, he argues, is almost certainly doomed to failure.
  • Somebody at a book-signing:  “I’ve always wanted to be a writer.  I could write a novel.” Me:  “Oh?  Why haven’t you?” Person:  “I just don’t have the time.” Me:  “Hmm.  Nobody gives me the time, either.  I have to make the time, set priorities, discipline myself to get my writing done each day, no matter how tired I am.  I worked a full-time regular job while I wrote my first novels, scraping out an hour here or there in evenings and weekends.  That’s how I’ve become a successful author.”
  • Even more striking is Exhibit C, the Edward Roybal Learning Center in the Westlake area, which was budgeted at $110 million until costs skyrocketed midway through construction when contractors discovered underground methane gas and a fault line. Eventual cost: $377 million. Mr. Rubin admits that the Roybal Center project was "a tremendous screw-up" that "should have been studied closer beforehand." The project was abandoned for several years, only to be recommenced when community activists demanded that the school be built at whatever cost necessary in order to show respect for the neighborhood's Latino children, many of whom were attending an overcrowded Belmont High School. The Roybal center now ranks in the bottom third of schools with similar demographics on state tests, while Belmont High ranks in the top third. But even though many Roybal kids can't read or do math, at least they have a dance studio with cushioned maple floors and a kitchen with a restaurant-quality pizza oven.
  • My next linguistical suggestion is more rigorous. It is to fight the "if-this-guy-wants-to-talk-to-that-guy" syndrome: never refer to parts of programs or pieces of equipment in an anthropomorphic terminology, nor allow your students to do so. This linguistical improvement is much harder to implement than you might think, and your department might consider the introduction of fines for violations, say a quarter for undergraduates, two quarters for graduate students, and five dollars for faculty members. The reason for this last suggestion is that the anthropomorphic metaphor —for whose introduction we can blame John von Neumann— is an enormous handicap for every computing community that has adopted it. I have now encountered programs wanting things, knowing things, expecting things, believing things, etc., and each time that gave rise to avoidable confusions. The analogy that underlies this personification is so shallow that it is not only misleading but also paralyzing.
  • It can be anything from cricket fans to stamp collectors. A social network that serves people with a shared interest is barely counts as a start-up idea at this stage. Naïvely a designer or developer starts one of these projects by gathering a feature set. How will our users communicate with each other? Will there be private communication too? Can they share details? What services will they want to integrate with? How can we get them connected as quickly as possible? Should they follow some users by default? Will we use OAuth to find their twitter friends? The list goes on.
  • The problem with Scott and his generation-- and this is most decidedly not Scott's fault but is the fault of his dad and grandfather's generations-- is that Scott just can't imagine playing without a net. "No, I'll just wait here, thank you, got myself an iced tea." This is what happens when you go through four years of college and don't at least read On The Road, let alone try it. "Start a business? From nothing? I don't know..." For him, debt should only be for a house, a school, and Polo shirts.

  • story behind popular job hunting book "And, over the past three decades, Bolles's preferred method has remained remarkably consistent: Sending out résumés doesn't work. Neither does answering ads. Employment agencies? No way. What does work is figuring out what you like to do and what you do well -- and then finding a place that needs people like you. Contact organizations that you're interested in, even if they don't have known vacancies. (Bolles actually coined the now commonplace term "informational interview.") Pester friends and family members for leads. Once you get in the door of the employer of your dreams, show how you can solve its problems."
  • But even after controlling for nearly all imaginable variables — socioeconomic status, level of physical activity, number of close friends, quality of social support and so on — the researchers (a six-member team led by psychologist Charles Holahan of the University of Texas at Austin) found that over a 20-year period, mortality rates were highest for those who were not current drinkers, regardless of whether they used to be alcoholics, second highest for heavy drinkers and lowest for moderate drinkers.

"That's what I find puzzling."

Groupon’s purchase form leads to mistakes

Groupon’s got a great business model: Subscribers get one offer every morning in their inbox from a local restaurant or business, and a time period to redeem that offer. They have tons of revenue. This morning I purchased my first Groupon. Even though I’m a pretty advanced computer user, I failed their purchase process and had to enter in my credit card data twice, as well as make two purchases. Let’s break down why it happened.

The offer was for Mr. Cecil’s California Ribs. I emailed a friend and she agreed it looked awesome, so I clicked on the link to make the purchase. Here’s their purchase page, which every user receives, unless they’ve previously logged into Groupon and set cookies to remember their login and password.

Note I’ve tried to buy two Groupons at the top of the form. I start entering in my personal information, password and credit card info. What I actually need to do is login first, like every customer that gets the Groupon emails.

After I’ve gotten out my credit card and punched in the information, I click “Complete My Order.” But I’m told by Groupon that my email address is already registered (of course, I subscribe to the email) and that I need to sign in first.

So I go back to the sign up form and click the light green “Sign In” button, which I’ve completely ignored up to this point. With the purchase information right there in front of me, why should I bother signing in?

Now that I’ve signed in, all of my information’s gone and I need to enter it all in again. I enter all my credit card and billing information again, and then get told “Congratulations! You’ve bought 1 Groupon for Cecil’s Ribs!” but of course I wanted to order two – Groupon reset the quantity while I was logging in.

Now I have to click on the deal again and click “Buy Groupon” to get one more. This time Groupon’s saved my credit card info, so I don’t have to enter it again. However, it’s generally not good practice to take people’s credit card information without their consent.

Finally I have my two Groupons. I’ve had to enter in my data twice and I’ve had to make two separate purchases. All in all, this is pretty bad usability for a well-known company, and I hope they fix it soon. They need to filter users with accounts from users without accounts, through a two-stage purchase screen, or email link magic, or allow everyone to make a purchase without using an account.

And now checking the site for the third time, I notice that you can only use one Groupon per table. All in all, a frustrating customer experience.

  • I wouldn’t have recognized him on the street and I didn’t know his name, but I knew him, or at least knew his body, and knew this odd habit of his. To put it in social-media terms, it was as if @weirdneighbor were tweeting, “I like playing piano in the nude. Whatever.” Because of the slant of the sun and the size of my windows, I don’t think he could see me, so our relationship, as it were, was less like Facebook, where the exchange is mutual, and more like Twitter: in other words, I was “following” him, but he wasn’t following me.

The school is being funded as any other public school in the state. School districts that have students attending the school will have to pay Greenfield up to $5,000 per student.

  • n both books we observed that payroll and wins in baseball do not have a strong correlation. Specifically, a team’s payroll only explains about 20% of a team’s wins. This means that it takes more than dollars to win in baseball. And this means that simply taking money from the rich teams and giving it to the poor teams is not going to transform baseball’s lower classes into winners. The Pirates appear to be agreeing with this observation. Rather than spend all the revenue sharing money – which may or may not lead to many more wins – the Pirates have decided to just keep part of this money as profits.

  • Libertarians are an increasingly vocal ideological group in U.S. politics, yet they are understudied compared to liberals and conservatives. Much of what is known about libertarians is based on the writing of libertarian intellectuals and political leaders, rather than surveying libertarians in the general population. Across three studies, 15 measures, and a large web-based sample (N = 152,239), we sought to understand the morality of selfdescribed libertarians. We found that, compared to liberals and conservatives, libertarians show 1) stronger endorsement of individual liberty as their foremost guiding principle and correspondingly weaker endorsement of other moral principles, 2) a relatively cerebral as opposed to emotional intellectual style, and 3) lower interdependence and social relatedness. Our findings add to a growing recognition of the role of psychological predispositions in the organization of political attitudes.
  • excellent, will blog soon: "Most academic efforts to understand morality and ideology come from theorists who constrain the moral domain to issues of harm and fairness. For such theorists, conservative beliefs are puzzles requiring non-moral explanations. In contrast, we present the "five foundations theory of intuitive ethics," which broadens the moral domain to match the anthropological literature on morality. We extend the theory by integrating it with a review of the sociological constructs of community, authority, and sacredness, as formulated by Emile Durkheim and others. We present data supporting the theory, which also shows that liberals may have a special difficulty in understanding the morality of conservatives. We suggest that what liberals see as a non-moral motivation for system justification may be better described as a moral motivation to protect society, groups, and the structures and constraints that are often (though not always) beneficial for individuals."

  • devastating palin takedown. too bad the audience we need to persuade doesn't read vanity fair After starting her new career as a national figure, Palin disengaged from the community. When in Wasilla, she rarely leaves the house. At her favorite coffee shop, Mocha Moose, Palin has been seen only once in the past three months. On those occasions when she goes to Church on the Rock, she usually arrives late, leaves early, and sits in the back. For runs to Target, she waits until it’s almost closing time. She has never darkened the doorway of Wasilla’s one independent bookstore, Pandemonium Booksellers, which took part in her Going Rogue book signing at the Curtis D. Menard Memorial Sports Center. Sarah’s mother, Sally Heath, is a charter member of the Valley Republican Women’s Club, which sells a batch of Palin-family recipes for $5, but Palin has not been to any of their meetings since resigning as governor.
