Consumers of porn have more feminist attitudes

Filed under: Cancon, Health, Media — Tags: , , , — Nicholas @ 02:00

We’ve all heard the claim that pornography desensitizes those who view it and dehumanizes women … except that doesn’t seem to be the case, if a recent study is accurate:

The study, published in The Journal of Sex Research, was conducted by researchers at the University of Western Ontario. “According to radical feminist theory, pornography serves to further the subordination of women by training its users, males and females alike, to view women as little more than sex objects over whom men should have complete control,” they wrote in the study abstract.

Yet after comparing people who watch porn with those who don’t, researchers found those who had watched an adult film at least once in the past year held more egalitarian ideas about women in positions of power and women working outside the home, along with more positive views toward abortion. The two groups did not differ significantly in attitudes about “traditional” families or self-identification as feminist.

“Taken together, the results of this study fail to support the view that pornography is an efficient deliverer of ‘women-hating ideology,'” study authors concluded. “While unexpected from the perspective of radical feminist theory, these results are consistent with a small number of empirical studies that have also reported positive associations between pornography use and egalitarian attitudes.”

Researchers relied on data collected between 1975 and 2010 for the General Social Survey, which asks Americans about a wide range of social issues and personal views (including gender equality and personal pornography consumption). For both men and women, viewing porn was associated with more positive attitudes toward women holding positions of power, less negative views of abortion, and less negative attitudes toward women in the workplace.

QotD: The historical triumph of public health

Filed under: Bureaucracy, Government, Health, History, Quotations — Tags: , — Nicholas @ 01:00

… the great public health achievements between roughly 1850 and 1960. Doctors and public health experts were given extraordinarily broad powers by the government, and they used them to eliminate the scourges that had made cities into pestholes from time immemorial. They built gleaming sewers and water treatment plants to wipe out virulent water-borne pathogens that used to regularly claim thousands of lives. Contact-tracing and quarantine of airborne and sexually transmitted diseases turned former plagues like smallpox and syphilis into tragic but sporadic outbreaks. Changes in building codes helped beat back mass killers like tuberculosis. Poison control cut down on both accidental and deliberate deaths. The Pure Food and Drug Act, and similar ordinances in other countries, reduced foodborne illness, and also, the casual acquisition of opiate or cocaine addictions through patent medicines. Malarial swamps were drained. Environmental toxins were identified and banned. Then they went and invented antibiotics and vaccines and vaccination laws, and suddenly surgery was as safe as a long-haul flight, TB was curable, and childhood illnesses that used to kill hundreds of people every year were a quaint footnote in your 10th-grade history textbook.

Having seen public experts work these miracles through the heavy hand of the state, people understandably concluded we could use miracles in other areas. They had a metaphor, so to speak. The metaphor wasn’t very good, as is often the case, but it took a while to find out that you couldn’t solve a problem in your steel supply chain with the same system that was so good at tracing cholera outbreaks to tainted pumps.

[…]

This is an overreaction to a terrible failure, for two reasons. First, big bureaucracies fail all the time, especially in the face of novel threats. A large institution is like a battleship: hard to sink, but also hard to turn. Public health experts of earlier eras made grave mistakes, like dumping London’s untreated sewage into the Thames; public health experts of the future will too. The more important question is whether they correct themselves, as it seems to me the CDC is now doing.

The second is that this is not your grandfather’s public health system. Public health experts were, in a way, too successful; they beat back our infectious disease load to the point where most of us have never had anything more serious than Human papillomavirus or a bad case of the flu. This left them without that much to do. So they reinvented themselves as the overseers of everything that might make us unhealthy, from French Fries to work stress.

As with the steel mills, these problems are not necessarily amenable to the organizational tools used to tackle tuberculosis. The more the public and private health system are focused on these problems, the less optimized they will be for fighting the war against infectious disease. It is less surprising to find that they didn’t know how to respond to a novel infectious disease than it would have been to discover that they botched a new campaign against texting and driving.

QotD: This explains so much

Filed under: Health, Humour, Quotations, Science — Tags: , — Nicholas @ 01:00

The entire brain weighs three pounds (1.4 kg) and so is only a small percentage of an adult’s total body weight, typically 2%. But it consumes 20% of all the energy the body uses. Why? The perhaps oversimplified answer is that time is energy.

Neural communication is very rapid — it has to be — reaching speeds of over 300 miles per hour and with neurons communicating with one another hundreds of times per second. The voltage output of a single resting neuron is 70 millivolts, about the same as the line output of an iPod. If you could hook up a neuron to a pair of earbuds, you could actually hear its rhythmic output as a series of clicks.

[…]

Neurochemicals that control communication between neurons are manufactured in the brain itself. These include some relatively well-known ones such as serotonin, dopamine, oxytocin, and epinephrine, as well as acetylcholine, GABA, glutamate, and endocannabinoids. Chemicals are released in very specific locations and they act on specific synapses to change the flow of information in the brain. Manufacturing these chemicals, and dispersing them to regulate and modulate brain activity, requires energy — neurons are living cells with a metabolism, and they get that energy from glucose. No other tissue in the body relies solely on glucose for energy except the testes. (This is why men occasionally experience a battle for resources between their brains and their glands.)

Carbohydrates and fatty foods

Filed under: Food, Health, Science, USA — Tags: — Nicholas @ 04:00

Amy Alkon glories in her current dietary choices:

I spend my whole day eating fat — bacon fat, kale cooked in bacon fat, an omelet with cheese and pate, coffee made with half ‘n’ half; and steak, sausage, cheese, and green beans swimming in butter. Oh, also, a tablespoon of coconut oil warmed in half ‘n’ half a few times a day, whenever my brain feels like it’s on fire from intense activity.

I have never felt better.

And I’m never hungry the way I would get when I ate low-fat/high-carb — a hunger that made me feel like I could stop and devour a road sign (and anyone unlucky enough to be standing next to it at the time).

On the subject of hunger’s effect on diet maintenance, Gary Taubes has an op-ed in The New York Times that describes a study, taking place toward the end of World War Ii, that placed men on a starvation diet:

    For 24 weeks, these men were semi-starved, fed not quite 1,600 calories a day of foods chosen to represent the fare of European famine areas: “whole-wheat bread, potatoes, cereals and considerable amounts of turnips and cabbage” with “token amounts” of meat and dairy.

    As diets go, it was what nutritionists today would consider a low-calorie, and very low-fat diet, with only 17 percent of calories coming from fat.

There were horrible physical effects — and psychological ones. Two men had breakdowns. And then, when they were allowed to eat normally, they consumed “prodigious” amounts of food…eating themselves into “post-starvation obesity,” in the researchers’ words.

[…]

    Questions like these about the relationship between calories, macronutrients and hunger have haunted nutrition and obesity research since the late 1940s. But rarely are they asked. We believe so implicitly in the rationale of eat less, move more, that we (at least those of us who are lean) will implicitly fault the obese for their failures to sustain a calorie-restricted regimen, without ever apparently asking ourselves whether we could sustain it either. I have a colleague who spent his research career studying hunger. Asking people to eat less, he says, is like asking them to breathe less. It sounds reasonable, so long as you don’t expect them to keep it up for long.

Britain’s National Health Service runs up a “deficit of almost £1 billion in just three months”

Filed under: Britain, Government, Health — Tags: , — Nicholas @ 04:00

In the Telegraph a report on the dire financial straits of Britain’s NHS:

NHS trusts in England have racked up a deficit approaching £1 billion in the first three months of the financial year – the worst financial position “in a generation,” regulators have said.

The figure is more than the £820 million overspend for the entire previous year.

Experts warned of a looming winter crisis.

They said the “staggering” figures would result in widespread cutbacks to services, with lengthening waiting times and increased rationing of care.

The statistics for April to June show an overall deficit of £930m across England’s 241 NHS hospital trusts, with three in four trusts in the red.

The statistics show NHS Foundation Trusts had a deficit of £445 million. Other NHS trusts ended the first quarter of the year £485 million in deficit.

The foundation trust sector is under “massive pressure” and can no longer afford to go on as it is, the financial regulator Monitor said.

Regulators said an “over-reliance” on agency nurses and doctors to plug shortages of staff was fuelling the growing debt, which is forecast to reach a record high.

“[P]harmaceutical companies … make out like bandits from the existence of the patent system”

Filed under: Bureaucracy, Business, Health, Law, USA — Tags: , , , — Nicholas @ 05:00

The current US patent system is set up to create and maintain — for a limited time — monopolies that can be exploited by pharmaceutical companies:

The Wall Street Journal has a puzzling piece complaining about how the pharmaceutical companies seem to make out like bandits from the existence of the patent system. What puzzles is that the entire point and purpose of the patent system, in an economic sense, is so that inventors of things can make out like bandits. The background problem is that of public goods, something I’ll explain in a moment. That problem leads us to thinking that a pure free market in things which are public goods isn’t going to work as well as something a little different. So, we design something a little different. And the point and purpose of our design is so that people who innovate can make vast mountains of cash out of having done so.

It’s then more than a bit odd to point out that our system enables people who innovate to make vast mountains of cash.

[…]

Which brings us to the subtlety of those pricing decisions. With drugs, pharmaceuticals, close enough the cost of manufacturing a dose is zero. All of the costs go in the original research, the clinical testing (the lion’s share) and getting it through the FDA. Profit is therefore determined, since marginal production costs are zero (they’re not, accurately, but close enough for this comparison), by gross revenue. And we want to maximise the incentive for people to innovate, that’s the very reason we’ve got this patent system in the first place, and thus we would rather like the pharma companies to be maximising revenue.

And thus, from this economic point of view, we should be quite happy with people raising their prices. Demand does fall as they do so, yes, but as long as gross revenue increases, the price rises more than compensating for the fall in unit demand, then we should be happy with the way the system is working. Gross revenue is being maximised, profits are being maximised, incentives to innovate are being maximised. That’s what we want our system to do after all.

Far from being worried about this price gouging we should be welcoming it. Because, obviously, someone making bajillions out of having innovated a drug to cure a disease increases the incentives for many other people to go and invest bajillions of their own to cure other diseases. Far from complaining about it we should be celebrating the system working.

Your daily recommended minimum intake of water

Filed under: Food, Health, Science — Tags: — Nicholas @ 02:00

I’m sure you’ve heard variations on the notion that we’re all effectively dehydrated and should drink more water … where “more” is defined as a minimum of 64 ounces of water. It’s pseudo-scientific bullshit, as you may have already decided for yourself:

If there is one health myth that will not die, it is this: You should drink eight glasses of water a day.

It’s just not true. There is no science behind it.

And yet every summer we are inundated with news media reports warning that dehydration is dangerous and also ubiquitous.

These reports work up a fear that otherwise healthy adults and children are walking around dehydrated, even that dehydration has reached epidemic proportions.

Let’s put these claims under scrutiny.

I was a co-author of a paper back in 2007 in the BMJ on medical myths. The first myth was that people should drink at least eight 8-ounce glasses of water a day. This paper got more media attention (even in The Times) than pretty much any other research I’ve ever done.

It made no difference. When, two years later, we published a book on medical myths that once again debunked the idea that we need eight glasses of water a day, I thought it would persuade people to stop worrying. I was wrong again.

Many people believe that the source of this myth was a 1945 Food and Nutrition Board recommendation that said people need about 2.5 liters of water a day. But they ignored the sentence that followed closely behind. It read, “Most of this quantity is contained in prepared foods.”

“A head of iceberg lettuce has the same water content as a bottle of Evian”

Filed under: Food, Health, Science — Nicholas @ 03:00

Another older article that I neglected to blog when it was still fresh and green on the … shelf. Here’s a few less-than-appetizing facts about salad vegetables:

Salad vegetables are pitifully low in nutrition. The biggest thing wrong with salads is lettuce, and the biggest thing wrong with lettuce is that it’s a leafy-green waste of resources.

In July, when I wrote a piece defending corn on the calories-per-acre metric, a number of people wrote to tell me I was ignoring nutrition. Which I was. Not because nutrition isn’t important, but because we get all the nutrition we need in a fraction of our recommended daily calories, and filling in the rest of the day’s food is a job for crops like corn. But if you think nutrition is the most important metric, don’t direct your ire at corn. Turn instead to lettuce.

One of the people I heard from about nutrition is researcher Charles Benbrook. He and colleague Donald Davis developed a nutrient quality index — a way to rate foods based on how much of 27 nutrients they contain. Four of the five lowest-ranking vegetables (by serving size) are salad ingredients: cucumbers, radishes, iceberg lettuce and celery. (The fifth is eggplant.)

Those foods’ nutritional profile can be partly explained by one simple fact: They’re almost all water. Although water figures prominently in just about every vegetable (the sweet potato, one of the least watery, is 77 percent), those four salad vegetables top the list at 95 to 97 percent water. A head of iceberg lettuce has the same water content as a bottle of Evian (1-liter size: 96 percent water, 4 percent bottle) and is only marginally more nutritious.

Take collard greens. They are 90 percent water, which still sounds like a lot. But it means that, compared with lettuce, every pound of collard greens contains about twice as much stuff that isn’t water, which, of course, is where the nutrition lives. But you’re also likely to eat much more of them, because you cook them. A large serving of lettuce feels like a bona fide vegetable, but when you saute it (not that I’m recommending that), you’ll see that two cups of romaine cooks down to a bite or two.

The corollary to the nutrition problem is the expense problem. The makings of a green salad — say, a head of lettuce, a cucumber and a bunch of radishes — cost about $3 at my supermarket. For that, I could buy more than two pounds of broccoli, sweet potatoes or just about any frozen vegetable going, any of which would make for a much more nutritious side dish to my roast chicken.

Lettuce is a vehicle to transport refrigerated water from farm to table. When we switch to vegetables that are twice as nutritious — like those collards or tomatoes or green beans — not only do we free up half the acres now growing lettuce, we cut back on the fossil fuels and other resources needed for transport and storage.

Save the planet, skip the salad.

Helicopter parents have raised a generation of needy, emotionally fragile young adults

Filed under: Education, Health, Quotations, USA — Tags: , , , , — Nicholas @ 02:00

In Psychology Today, Peter Gray looks at how universities are unequipped to handle the anxieties and emotional neediness of today’s students:

A year ago I received an invitation from the head of Counseling Services to join other faculty and administrators, at the university I’m associated with, for discussions about how to deal with the decline in resilience among students. At the first meeting, we learned that emergency calls to Counseling had more than doubled over the past five years. Students are increasingly seeking help for, and apparently having emotional crises over, problems of everyday life. Recent examples mentioned included a student who felt traumatized because her roommate had called her a “bitch” and two students who had sought counseling because they had seen a mouse in their off-campus apartment. The latter two also called the police, who kindly arrived and set a mousetrap for them.

Faculty at the meetings noted that students’ emotional fragility has become a serious problem when in comes to grading. Some said they had grown afraid to give low grades for poor performance, because of the subsequent emotional crises they would have to deal with in their offices. Many students, they said, now view a C, or sometimes even a B, as failure, and they interpret such “failure” as the end of the world. Faculty also noted an increased tendency for students to blame them (the faculty) for low grades—they weren’t explicit enough in telling the students just what the test would cover or just what would distinguish a good paper from a bad one. They described an increased tendency to see a poor grade as reason to complain rather than as reason to study more, or more effectively. Much of the discussions had to do with the amount of handholding faculty should do versus the degree to which the response should be something like, “Buck up, this is college.” Does the first response simply play into and perpetuate students’ neediness and unwillingness to take responsibility? Does the second response create the possibility of serious emotional breakdown, or, who knows, maybe even suicide?

Two weeks ago, the head of Counseling (who has now moved up to another position in the University) sent us all a follow-up email, announcing a new set of meetings. His email included this sobering paragraph: “I have done a considerable amount of reading and research in recent months on the topic of resilience in college students. Our students are no different from what is being reported across the country on the state of late adolescence/early adulthood. There has been an increase in diagnosable mental health problems, but there has also been a decrease in the ability of many young people to manage the everyday bumps in the road of life. Whether we want it or not, these students are bringing their struggles to their teachers and others on campus who deal with students on a day-to-day basis. The lack of resilience is interfering with the academic mission of the University and is thwarting the emotional and personal development of students.”

[…]

In my next essay in this series I’ll examine the research evidence suggesting that so-called “helicopter parenting” really is at the core of the problem. But I don’t blame parents, or certainly not just parents. Parents are in some ways victims of larger forces in the society — victims of the continuous exhortations from “experts” about the dangers of letting kids be, victims of the increased power of the school system and the schooling mentality that says kids develop best when carefully guided and supervised by adults, and victims of increased legal and social sanctions for allowing kids into public spaces without adult accompaniment. We have become, unfortunately, a “helicopter society.”

If we want to prepare our kids for college — or for anything else in life! — we have to counter all these social forces. We have to give our children the freedom, which children have always enjoyed in the past, to get away from adults so they can practice being adults, that is, practice taking responsibility for themselves.

Universities, alcohol, women, and consent

Filed under: Health, Law, Politics, USA — Tags: , , , , — Nicholas @ 04:00

At Simple Justice, Scott Greenfield includes a poster from Southeast Missouri State University that nicely summarizes both the institutional infantilization of university students and the current double standard on booze and consent rules:

University students, booze and consent

There is universal agreement that any female (though not male) who has passed out is incapable of giving consent to sex. But as the spectrum of reaction to alcohol or drugs comes closer to the sober end, it becomes increasingly problematic. The word used to describe a woman who cannot consent is “incapacitation.”

What is incapacitation? That’s impossible to say. It usually described by either specific instances of conduct (“if she’s puking her guts out, that means she’s incapacitated”), which offers no guidance when she’s not puking her guts out, or when she’s done puking her guts out, or before she’s puking her guts out.

The underlying rationale is that a woman who is so drunk that she cannot formulate knowing, intentional and voluntary consent, cannot consent to sex. This is a dubious standard, as the incapacity to consent doesn’t mean she would not consent, but that she cannot consent.

To put this in context, consider a person who fully consents, enthusiastically desires to engage in conduct, but wasn’t specifically asked beforehand. This person can truthfully assert that it was non-consensual under the Affirmative Consent standard, because she never overtly expressed consent.* The objective standard is not met, although the subjective standard is fully met.

The problem is reminiscent of drunk driving, which was determined by the objective inability to perform the tasks necessary to safely drive a car before the law turned to Blood Alcohol Content as a proxy, an inadequate measure but a convenient one for law enforcement to prove. Sexual incapacitation suffers from a lack of definition and no objective basis.

What is clear about incapacitation is that it’s not when there is “liquor in the cup,” or when “she has touched alcohol,” any more than it would be a crime for her to thereafter get behind the wheel of a car. Yet, the notion that any alcohol (or drugs, which don’t seem to find their way onto posters or flyers as much) per se vitiates consent is spreading and being used as the hard and fast line.

A unique genetic population in the Dominican Republic

Filed under: Americas, Health, Science — Tags: , , , — Nicholas @ 03:00

BBC Magazine on the extraordinary lives of the Guevedoces, children who suddenly develop male sexual characteristics at puberty:

The discovery of a small community in the Dominican Republic, where some males are born looking like girls and only grow penises at puberty, has led to the development of a blockbuster drug that has helped millions of people, writes Michael Mosley.

Johnny lives in a small town in the Dominican Republic where he, and others like him, are known as “Guevedoces“, which effectively translates as “penis at twelve”.

We came across Johnny when we were filming for a new BBC Two series Countdown to Life, which looks at how we develop in the womb and how those changes, normal and abnormal, impact us later in life.

Like the other Guevedoces, Johnny was brought up as a girl because he had no visible testes or penis and what appeared to be a vagina. It is only when he approached puberty that his penis grew and testicles descended.

[…]

So why does it happen? Well, one of the first people to study this unusual condition was Dr Julianne Imperato-McGinley, from Cornell Medical College in New York. In the 1970s she made her way to this remote part of the Dominican Republic, drawn by extraordinary reports of girls turning into boys.

When she got there she found the rumours were true. She did lots of studies on the Guevedoces (including what must have been rather painful biopsies of their testicles) before finally unravelling the mystery of what was going on.

When you are conceived you normally have a pair of X chromosomes if you are to become a girl and a set of XY chromosomes if you are destined to be male.

For the first weeks of life in womb you are neither, though in both sexes nipples start to grow.

Then, around eight weeks after conception, the sex hormones kick in. If you’re genetically male the Y chromosome instructs your gonads to become testicles and sends testosterone to a structure called the tubercle, where it is converted into a more potent hormone called dihydro-testosterone This in turn transforms the tubercle into a penis. If you’re female and you don’t make dihydro-testosterone then your tubercle becomes a clitoris.

External Benefits

Filed under: Economics, Health — Tags: , , , , — Nicholas @ 04:00

Published on 18 Mar 2015

What can the flu teach us about economics and externalities? In this video, we go over how vaccines produce positive externalities that help people stay healthy. When someone receive the vaccine, they pass along the positive benefits of the vaccine to others, generating positive externalities. However, when someone gets a vaccine, they bear all of the costs and only reap some of the benefits of the vaccine. The social value is larger than the private value, resulting in an an undersupply of flu shots. One solution to this problem is a Pigouvian subsidy — a subsidy on a good with external benefits.

What are externalities and what are the different kinds of costs? And what does this have to do with the rise of “superbugs”? This video is an introduction to externalities, including the concepts of private cost, external cost, and social cost. Using the example of antibiotics and viruses, we take a look at how costs are passed along to different members of society beyond the producer and consumer. We’ll use a chart to illustrate how to calculate the effects of a Pigouvian tax, and we provide definitions for the other key terms that will be used throughout this video series.

Teaching microaggressions

Filed under: Health, Politics, USA — Tags: , , , , — Nicholas @ 04:00

At Ace of Spades HQ, Ace sums up the deepest problem with the movement to find microaggressions everywhere and in everything:

The idea is that just as cognitive therapy teaches people to not make a big deal out of trivialities (like teaching people who have a phobia about elevators to learn to not be afraid of elevators), microagression brain-programming is a malicious form of cognitive therapy teaching people the exact opposite — to fear this, hate that, fly off the handle about this other thing, and generally carry on like a lunatic about things that sane people do not even think about.

And just as the good form of cognitive therapy can make a hysteric or neurotic a well-functioning individual, so can the insidious form of it turn a well-functioning individual into a hysteric or neurotic.

I think it’s 100% right and I’m glad someone had the guts to say so.

Colleges and progressives generally are teaching young people how to be mentally ill.

Pessimism and doom-mongering still sells books and movies

Filed under: Books, Environment, Health, Media, Science — Tags: , , , — Nicholas @ 04:00

Gregg Easterbrook reviews The End of Doom by Ronald Bailey:

Outside your window, living standards are rising, crime is declining, pollution is down, and longevity is increasing. But in pop culture, we’re all doomed. The Hunger Games films have been box-office titans, joined by World War Z, Interstellar, The Book of Eli, Divergent, The Road, and other big-budget Hollywood fare depicting various judgment days. Over in primetime, the world is ending on The Walking Dead, The Last Ship, The 100, and Under the Dome.

The same outlook obtains in nonfiction literature. Books that foresee doomsday — Collapse by Jared Diamond, The End of Nature by Bill McKibben, The Coming Plague by Laurie Garrett among them — win praise from commentators and sell briskly. Books contending that things basically are fine don’t do as well. One might think that optimism would be marketable to contemporary book buyers, who live very well by historical standards, but it doesn’t seem to work that way. Readers prefer material that depicts them dwelling in the final generation. Perhaps declining religious belief in Armageddon has been replaced by an expectation of some natural-world version of the event.

Into this adverse market steps The End of Doom by Ronald Bailey, an impressively researched, voluminously detailed book arguing that the world is in better shape than commonly assumed. Bailey deflates doomsday by showing that human population growth does not mean ecological breakdown; that food supply increases faster than population and probably always will; that, far from depleted, most resources are sufficient to last for centuries; that air pollution in the United States is way down; and that cancer is in decline.

Specialists will argue about some of the studies Bailey cites to support these contentions. So much environmental research exists today, for example, that one can find a study to prove practically anything. But in the main, Bailey’s selection of research is fastidious and convincing.

Bailey spends too much time, though, on discredited trendy bleakness from the 1960s and 1970s — such as Paul Ehrlich’s global-famine predictions and the 1972 Club of Rome report. One can practically hear dead horses saying, “Stop flogging me.” The End of Doom redeems itself with a clever chapter on how precautionary principles boil down to this rule: never do anything for the first time. “Anything new is guilty until proven innocent,” Bailey writes, but he goes on to chronicle how many new ideas denounced as dangerous turned out instead to make life less risky.
