Iatrogenic hypertension

Filed under: Bureaucracy, Health — Tags: , — Nicholas @ 12:17

It’s possible that millions of people are on high blood pressure medication today who don’t really need to be:

Currently, anyone suspected of having high blood pressure is diagnosed by a GP with an inflatable arm cuff. Doctors then call the patient back for additional readings, but these are always taken at their surgery or in hospital.

New draft guidance to be published today by the National Institute for Health and Clinical Excellence (Nice) says as many as one in four people experiences a surging pulse rate on entering a GP’s surgery.

This nervous response, termed “white coat hypertension”, can significantly raise blood pressure readings and many people are being misdiagnosed as a result.

To counter this, Nice is recommending that doctors do not rely solely on readings taken in their own surgeries. After the initial assessment, a patient should be sent home and asked to wear an ambulatory blood pressure monitoring (ABPM) device.

A suspicious mind might wonder if there’s a financial benefit to drug companies large enough to have them pressure physicians to diagnose high blood pressure even in people whose readings are not far off normal.

This just in: men still suck, say women

Filed under: Randomness — Tags: , , — Nicholas @ 11:30

From the Wall Street Journal:

Not so long ago, the average American man in his 20s had achieved most of the milestones of adulthood: a high-school diploma, financial independence, marriage and children. Today, most men in their 20s hang out in a novel sort of limbo, a hybrid state of semi-hormonal adolescence and responsible self-reliance. This “pre-adulthood” has much to recommend it, especially for the college-educated. But it’s time to state what has become obvious to legions of frustrated young women: It doesn’t bring out the best in men.

“We are sick of hooking up with guys,” writes the comedian Julie Klausner, author of a touchingly funny 2010 book, “I Don’t Care About Your Band: What I Learned from Indie Rockers, Trust Funders, Pornographers, Felons, Faux-Sensitive Hipsters and Other Guys I’ve Dated.” What Ms. Klausner means by “guys” is males who are not boys or men but something in between. “Guys talk about ‘Star Wars’ like it’s not a movie made for people half their age; a guy’s idea of a perfect night is a hang around the PlayStation with his bandmates, or a trip to Vegas with his college friends…. They are more like the kids we babysat than the dads who drove us home.” One female reviewer of Ms. Kausner’s book wrote, “I had to stop several times while reading and think: Wait, did I date this same guy?”

[. . .]

But for all its familiarity, pre-adulthood represents a momentous sociological development. It’s no exaggeration to say that having large numbers of single young men and women living independently, while also having enough disposable income to avoid ever messing up their kitchens, is something entirely new in human experience. Yes, at other points in Western history young people have waited well into their 20s to marry, and yes, office girls and bachelor lawyers have been working and finding amusement in cities for more than a century. But their numbers and their money supply were always relatively small. Today’s pre-adults are a different matter. They are a major demographic event.

What also makes pre-adulthood something new is its radical reversal of the sexual hierarchy. Among pre-adults, women are the first sex. They graduate from college in greater numbers (among Americans ages 25 to 34, 34% of women now have a bachelor’s degree but just 27% of men), and they have higher GPAs. As most professors tell it, they also have more confidence and drive. These strengths carry women through their 20s, when they are more likely than men to be in grad school and making strides in the workplace. In a number of cities, they are even out-earning their brothers and boyfriends.

And that last point begins to answer the question “Where Have The Good Men Gone?” Women traditionally look to find men who earn more and/or have higher academic and social position. Now that women are beginning to out-earn and out-compete men, it has the paradoxical result of reducing the pool of available men with the requisite higher financial or social capital. There are more women competing for fewer men. This trend will only increase in western society.

This came up last month, and will probably be a very common theme for books and magazine articles in the coming year.

Human hacking: the overconfident CEO

Filed under: Law, Media, Technology — Tags: , , , — Nicholas @ 07:19

An interesting story at PC World talks about the methods used to get inside information on individuals and companies:

“He was the guy who was never going to fall for this,” said Hadnagy. “He was thinking someone would probably call and ask for his password and he was ready for an approach like that.”

After some information gathering, Hadnagy found the locations of servers, IP addresses, email addresses, phone numbers, physical addresses, mail servers, employee names and titles, and much more. But the real prize of knowledge came when Hadnagy managed to learn the CEO had a family member that had battled cancer, and lived. As a result, he was interested and involved in cancer fundraising and research. Through Facebook, he was also able to get other personal details about the CEO, such as his favorite restaurant and sports team.

Armed with the information, he was ready to strike. He called the CEO and posed as a fundraiser from a cancer charity the CEO had dealt with in the past. He informed him they were offering a prize drawing in exchange for donations — and the prizes included tickets to a game played by his favorite sports team, as well as gift certificates to several restaurants, including his favorite spot.

The CEO bit, and agreed to let Hadnagy send him a PDF with more information on the fund drive. He even managed to get the CEO to tell him which version of Adobe reader he was running because, he told the CEO “I want to make sure I’m sending you a PDF you can read.” Soon after he sent the PDF, the CEO opened it, installing a shell that allowed Hadnagy to access his machine.

When Hadnagy and his partner reported back to the company about their success with breaching the CEO’s computer, the CEO was understandably angry, said Hadnagy.

“He felt it was unfair we used something like that, but this is how the world works,” said Hadnagy. “A malicious hacker would not think twice about using that information against him.”

Takeaway 1: No information, regardless of its personal or emotional nature, is off limits for a social engineer seeking to do harm

Takeaway 2: It is often the person who thinks he is most secure who poses the biggest vulnerability. One security consultant recently told CSO that executives are the easiest social engineering targets.

Workplace diplomacy

Filed under: Bureaucracy, Randomness — Tags: , , — Nicholas @ 12:42

An aside to an email discussion we were having provoked DarkWaterMuse to post his thoughts on the matter:

Diplomacy is a major cause of workplace inefficiency. Mostly, it doesn’t actually matter how things get said.

dwm tends to say whatever is rattling around at the top of his head. Too often what rattles around up there then manages to roll down mysterious passageways carved throughout his brain before it tumbles off the tip of his tongue.

Sometimes the words that escape just lay there, stunned and motionless on the floor, as other people in earshot simply glare at them.

Even worse though is when dwm doesn’t say anything at all. That probably means either there’s a log jam of words building up pressure inside his head, a clear sign of imminent unbounded and unpredictable cranial flatulence, or he’s mentally undressing one of the women who happens to be trapped in the same meeting room.

dwm has never really appreciated the need for diplomacy. Especially when there’s clearly work to be done. He subscribes to the notion that people like to be part of success, however it manages to manifest.

As it turns out, diplomacy isn’t necessary for success. It’s just necessary to manage the people who aren’t focused on it.

I’m not convinced, as I’ve found diplomacy to be one of the most frequently used “tools” in my arsenal. I suspect DarkWaterMuse, as primarily a “producer” of essentially original content has less functional need for the social lubricant of careful wording than someone like me (a “consumer” if you will), who generally requires the active co-operation of others to provide me with the raw material I happen to need to accomplish my tasks.

His point about diplomacy being “a major cause of workplace inefficiency” would more closely hit the mark if he were using it to describe weasel wording rather than diplomacy. As Sir Humphrey Appleby says “A good Civil Servant must be able to use language not as a window into the mind but as a curtain to draw across it.” What is ideal for a civil servant is toxic for good working relationships in non-bureaucratic environments.

UK government officials implicated in ADE-651 bomb detector scam

Filed under: Britain, Law, Middle East, Military, Technology — Tags: , , , — Nicholas @ 13:03

Remember the ADE-651? The bomb detector that could “detect elephants, humans and 100 dollar bills”? It now appears that British army personnel and civil servants were involved in the effort to sell the bogus device:

The government has admitted that the Army and UK civil servants helped market so-called “bomb detectors”, which did not work, around the world.

Export of the “magic wand” detectors to Iraq and Afghanistan was banned on 27 January 2010 because of the threat they posed to British and allied troops.

The move followed a BBC Newsnight investigation showing they could not detect explosives — or anything else.

Now Newsnight has learned that they are still being sold around the globe.

You can understand the attraction to potential scammers, as the things cost £11 to make (at most) and can be sold for £15,000 to unsuspecting dupes (or willing accomplices, splitting the profits) representing foreign governments.

QotD: The impermanence of “The Cloud”

Filed under: Quotations, Technology — Tags: , , , — Nicholas @ 15:13

We adopt many web services because they’re convenient (and free!), but it’s only after becoming dependent on those services that we recognize why they were provided for free in the first place: after all, it’s only by eliminating the inconvenience of paying users that startups can snag attention and secure the freedom to alter, downgrade, or cancel their services at will. By then, of course, we’re trapped in an unstable relationship, and our only means of recourse is to wail as loudly as possible, “You broke my heart!”

The big lesson that should have come out of the Tumbleocalypse was that we trust too easily. Did any of us listen? Nah. Instead, we’re signing our friends up to Dropbox to score 250 megs of bonus storage space and sending our most important documents to “the cloud.” We trust Dropbox because we trust others who use Dropbox: web designers, tech writers and professionals who, we believe, would never gamble with an unproven, flaky, or suspect service. Without this kind of trust-by-proxy, free web services couldn’t survive at all. Can you imagine anybody in their right mind signing up for a Facebook account today without a good friend by the sidelines whispering, “Don’t mind all that privacy whaffle. I know these guys mean well.”

Cloud storage is convenient, of course — ask anybody who’s experienced the horrors of manually synching PC to iPhone — but we downplay the risks involved in outsourcing control of the data we own. We so badly want to live in the future that we’ve lost the ability to question what living in the future might actually mean.

[. . .]

Those who believe that “the cloud” can act as a storage platform for our collective memories believe that everything that was available to us yesterday will be just as available to us tomorrow. Where exactly does this conviction come from?

The web is like any other sprawling city, and maybe worse: it’s so damn rickety it’s a minor miracle it hasn’t collapsed entirely. When you link, you do so trusting that the data to which you direct your readers won’t just up and disappear into the virtual ether. Except that, inevitably, it will — the short history of the web has established that much. We live somewhere, we leave, it becomes forgotten, and then we come back years later to find our old haunts brutally 404’d.

Mark Steyn on the state of Britain

Filed under: Britain, Education, Government, History — Tags: , — Nicholas @ 07:38

From a longer column on the general state of decline in the Anglosphere, Mark Steyn points out the negative aspects of British public education on modern day “Britons”:

In cutting off two generations of students from their cultural inheritance, the British state has engaged in what we will one day come to see as a form of child abuse, one that puts a huge question mark over the future. Why be surprised that legions of British Muslims sign up for the Taliban? These are young men who went to school in Luton and West Bromwich and learned nothing of their country of nominal citizenship other than that it’s responsible for racism, imperialism, colonialism, and all the other bad -isms of the world. If that’s all you knew of Britain, why would you feel any allegiance to Queen and country? And what if you don’t have Islam to turn to? The transformation of the British people is, in its own malign way, a remarkable achievement. Raised in schools that teach them nothing, they nevertheless pick up the gist of the matter, which is that their society is a racket founded on various historical injustices. The virtues Hayek admired? Ha! Strictly for suckers.

When William Beveridge laid out his blueprint for the modern British welfare state in 1942, his goal was the “abolition of want,” to be accomplished by “cooperation between the State and the individual.” In attempting to insulate the citizenry from the vicissitudes of fate, Sir William succeeded beyond his wildest dreams: Want has been all but abolished. Today, fewer and fewer Britons want to work, want to marry, want to raise children, want to lead a life of any purpose or dignity. Churchill called his book The History of the English-Speaking Peoples — not the English-Speaking Nations. The extraordinary role played by those nations in the creation and maintenance of the modern world derived from their human capital.

What happens when, as a matter of state policy, you debauch your human capital? The United Kingdom has the highest drug use in Europe, the highest incidence of sexually transmitted disease, the highest number of single mothers; marriage is all but defunct, except for toffs, upscale gays, and Muslims. For Americans, the quickest way to understand modern Britain is to look at what LBJ’s Great Society did to the black family and imagine it applied to the general population. One-fifth of British children are raised in homes in which no adult works. Just under 900,000 people have been off sick for over a decade, claiming “sick benefits,” week in, week out, for ten years and counting. “Indolence,” as Machiavelli understood, is the greatest enemy of a free society, but rarely has any state embraced this oldest temptation as literally as Britain. There is almost nothing you can’t get the government to pay for.

And this bit where he shows that the British government defies parody:

For its worshippers, Big Government becomes a kind of religion: the state as church. After the London Tube bombings, Gordon Brown began mulling over the creation of what he called a “British equivalent of the U.S. Fourth of July,” a new national holiday to bolster British identity. The Labour Party think-tank, the Fabian Society, proposed that the new “British Day” should be July 5th, the day the National Health Service was created. Because the essence of contemporary British identity is waiting two years for a hip operation. A national holiday every July 5th: They can call it Dependence Day.

Once again, correlation is not causation

Filed under: Britain, Media, Science — Tags: , , — Nicholas @ 12:50

An excellent example of what statistical analysis can and cannot show:

Do mobile phone towers make people more likely to procreate? Could it be possible that mobile phone radiation somehow aids fertilisation, or maybe there’s just something romantic about a mobile phone transmitter mast protruding from the landscape?

These questions are our natural response to learning that variation in the number of mobile phone masts across the country exactly matches variation in the number of live births. For every extra mobile phone mast in an area, there are 17.6 more babies born above the national average.

This was discovered by taking the publicly available data on the number of mobile phone masts in each county across the United Kingdom and then matching it against the live birth data for the same counties. When a regression line is calculated it has a “correlation coefficient” (a measure of how good the match is) of 98.1 out of 100. To be “statistically significant” a pattern in a dataset needs to be less than 5% likely to be found in random data (known as a “p-value”), and the masts-births correlation only has a 0.00003% probability of occurring by chance.

Part of the problem is that our brains have evolved to detect patterns and relationships — even when they’re not really there:

Mobile phone masts, however, have absolutely no bearing on the number of births. There is no causal link between the masts and the births despite the strong correlation. Both the number of mobile phone transmitters and the number of live births are linked to a third, independent factor: the local population size. As the population of an area goes up, so do both the number of mobile phone users and the number people giving birth.

The problem is that our first instinct is to assume that a correlation means that one factor is causing the other. While this does not cause a problem when using pattern-spotting as an evolved survival tool, it does cause severe problems when assessing possible health scares based on a recently uncovered correlation. For the majority of cases, correlation does not indicate the presence of causality.

Smug, but nursing that inferiority complex: urban Canada in a nutshell

Filed under: Cancon, Media, Politics — Tags: , , — Nicholas @ 01:28

John Geddes seems puzzled by the apparent contradiction:

Can we settle on the putdown of preference when it comes to right-wingers expressing their disdain for Canada?

They often resort to either of two seemingly contradictory, but equally condescending, lines about Canadians: we are insufferable in our sense of moral superiority, or we exhibit an equally tiresome inferiority complex.

Now, I’m willing to take my lumps, but do they have to come from both directions at once? Can’t you decide if my national ego is obnoxiously over-developed or pathetically under-developed?

I can only assume that Mr. Geddes hasn’t attended too many parties in Toronto or Ottawa. Both psychological maladies are often displayed by the same people . . . sometimes in the same conversation. Torontonians in particular are capable of sneering at vulgar Americans in one moment, then fretting that they don’t pay enough attention to our “world class” city in the next. Short of finding a way of expressing both thoughts simultaneously, I’d say that was a strong indication that urban Canadians can hold both thoughts without an overwhelming sense of contradiction.

This should be good for stirring up spirited debate

Sarah Bee reports on the kerfuffle around Satoshi Kanazawa’s book Ten Politically Incorrect Truths About Human Nature:

Women long for the classic Barbie figure with big boobs, long blonde hair and blue eyes because it makes men want to impregnate them, an evolutionary psychologist has proclaimed.

London School of Economics reader Satoshi Kanazawa has successfully manipulated the more malleable and shameless news outlets into excitedly regurgitating the provocative theories contained in his book, Ten Politically Incorrect Truths About Human Nature. He explains that the traditional attributes of the buxom blonde babe have evolutionary advantages, as the Daily Mail duly recounts.

Big boobs are supposedly indicative of fertility, along with a large waist-to-hip ratio. Blonde hair displays grey hairs less obviously, thus concealing age — men prefer the younger bird for a better shot at passing on their DNA, sensibly enough.

Blue eyes, Kanazawa points out, more clearly display pupil dilation, which occurs when the peepers’ owner sees something she likes. Thus a man can tell more quickly if a blue-eyed woman fancies a bit or not, saving precious sharking time at the bar.

Kanazawa further postulates that women are getting hotter and having lovelier daughters, while men are regrettably as fugly as ever they were. Beautiful women have more children than the overlooked homely types, and also have more female children, and on it goes in a wondrous babeification of the species.

This is a case where the science may point in a direction that is so politically and socially unwelcome that everyone just ignores it. Or it could be a huge joke to put the politically correct folks into a lather. Pick your option and season to taste.

The inevitable convergence of new technology with sex

Filed under: Media, Randomness, Technology — Tags: , — Nicholas @ 08:33

PC World looks at the latest convergence of all the sex-obsessed geeks in the world and the latest consumer electronics toys:

It’s practically the universal rule of electronics: Where there’s technology, there’s sex. Embrace it or shun it, but it’s the way of the world.

Now, it looks like Microsoft’s new Kinect may be the latest gadget to fall prey to prurient interests. The Kinect is undergoing a series of experiments designed to turn its motion-sensitive virtual gaming into motion-sensitive virtual mating.

Oh, come on — are you really that surprised?

The original term was “teledildonics”, which has the virtue of allowing you to discuss it without quite giving away the true subject.

If you want to know about the possibilities of Kinect sex, just ask Kyle Machulis. Machulis, aka “qdot,” runs a site called slashdong.org (Google it at your own risk). The site, which I probably shouldn’t mention by name more than once, focuses on the meeting point between sex and tech. It featured a blog this week exploring the idea of X-rated uses for Kinect-enabled Xboxes (hat tip to the crew from CNET for finding the page).

In the blog, Machulis — who was recently cited by New Scientist as a Kinect-hacking authority — observes how the Kinect is able to use depth in order to identify a person’s body shape. He goes on to note, however, that Microsoft’s gaming console really tracks the human body “as a whole,” looking at “major geometric features” of a user’s form. This doesn’t bode well for the prospect of Kinect sex; without getting too graphic, let’s just say that the primary anatomy involved in intimate relations isn’t exactly a “major geometric feature.” Sorry, fellas.

New technology is notoriously prone to being harnessed to the interests of prurience . . . after Gutenberg and his competitors got the mass-produced bible business going, one of the next profitable niches to be explored was the erotic/pornographic book market.
