In search of a grand, unifying theory of . . . porn?

Filed under: Science — Tags: , , , — Nicholas @ 08:37

Two different studies came to my attention dealing with people and pornography. (No, before you ask, the studies were not illustrated, and the pages didn’t stick together.) First up, Professors Martin Barker and Feona Attwood, and Dr Clarissa Smith tried to find out how individuals use porn:

The aim of this survey, available online at pornresearch.org, is to collect evidence around the everyday uses of pornography and find out how the people who use it feel it fits into their lives. Ultimately, the data may be used to challenge some of the assumptions now current in debate around the “sexualisation” of society.

Critics of the research have questioned whether such work is necessary, claiming that “everyone knows how porn is used”. Those behind the survey, Professors Martin Barker and Feona Attwood, and Dr Clarissa Smith, reader in sexual culture at the University of Sunderland, reckon that the real problem is that we don’t have the answers, and society is attempting to legislate in a vacuum.

While not denying the moral dimension of many of the questions, the researchers are concerned that the voices of users and enjoyers will be swamped by a prevailing critical assumption that the only issues worth considering are how problematic porn use is, or how it might affect children. The researchers believe that there can be many different and complicated reasons for looking at pornography and that not all the materials that go under that label are the same, only to be distinguished by how ‘extreme’ or ‘explicit’ they are.

Dr Smith told the Reg: “Although there is much speculation and plenty of academic work which insists on porn having demonstrable and problem ‘effects’ on users, I’ve been struck by how often researchers have told me there is no need for any empirical research on how and why porn is consumed.

You can imagine how studies like this would be resisted by other researchers who didn’t think of them first who might decry the work as being trivial and unnecessary.

On the other side of the Atlantic, researchers were more interested in the interaction between political events and the consumption of pornography:

Both Republicans and Democrats seek out internet porn to celebrate the victories of their candidates says a new study in the journal Computers in Human Behavior. The abstract from the article with the toe-curling social science title, “Pornography-seeking behaviors following midterm political elections in the United States: A replication of the challenge hypothesis” reports:

The current study examined a prediction derived from the challenge hypothesis; individuals who viciously win a competition of rank order will seek out pornography relatively more often than individuals who viciously lose a competition. By examining Google keyword searches during the 2006 and 2010 midterm elections in the United States, the relative popularity of various pornography keyword searches was computed for each state and the District of Columbia the week after each midterm election. Consistent with previous research examining presidential elections and the challenge hypothesis, individuals located in traditionally Republican states tended to search for pornography keywords relatively more often after the 2010 midterm election (a Republican victory) than after the 2006 midterm election (a Democratic victory). Conversely, individuals located in traditionally Democratic states tended to search for pornography relatively less often following the 2010 midterm election than they did following the 2006 midterm election.

Watch the Darwinian struggle of car evolution: http://www.boxcar2d.com/.

The program learns to build a car using a genetic algorithm. It starts with a population of 20 randomly generated shapes with wheels and runs each one to see how far it goes. The cars that go the furthest reproduce to produce offspring for the next generation. The offspring combine the traits of the parents to hopefully produce better cars. Now with the button at the bottom left u can choose to input cars and different terrains. This lets people post their results and even design a car by hand.

It uses a physics library called box2D to simulate the effects of gravity, friction, collisions, motor torque, and spring tension for the car. This lets the car be a wide range of shapes and sizes, while still making the simulation realistic. This is based on the AS3 box2D flash port of the library. Watch the demo of some of its capabilities.

My inspiration for this project comes from qubit.devisland.net/ga. My implementation uses the physics library to make the car a real object instead of two point masses. There are also many extra variables because of the complicated car and axles and the color cleary illustrates the evolution.

UK’s largest off-grid housing development

Filed under: Britain, Environment — Tags: , — Nicholas @ 07:37

If you’re really a fan of alternative energy, you might want to keep an eye on this new development in Brighton:

The six apartment buildings, to be built at the mouth of Shoreham port near Brighton, will be linked by wind turbines, and their southern face will be tiled in solar thermal and photovoltaics panels.

Batteries will be charged during the day in order to keep the lights on at night, and the apartments themselves will be heavily insulated in order to keep power use as low as possible.

But resident behaviour will also play a key role, says the developer, Colin Brace of Bohogreen, who has worked on previous low-carbon projects. “We can’t tell people that you only have so much power, and no more. But there are studies showing that if you give people renewable energy they think, oh good, it’s free, and their energy use actually goes up. So an important aspect of the project will be to educate people about their energy use.

“The apartments will be designed to encourage communal living as much as possible,” says Brace, “rather than having everyone in their own rooms using their own sources of power.” There will also be LED lights on the wind turbines which light up red, amber and green to show which block is using power most heavily, in order to foster “a healthy sense of competition between residents to keep their power use low”.

I wouldn’t want to live in a development where the neighbours are pre-selected for their “greener than thou” attitudes, frankly. The LED lights of shame would probably encourage more neighbour nosiness into the lives of the other residents.

Of course, all that healthy greenery comes at a slight premium to ordinary housing:

The apartments in Portzed will be up to 22% more expensive than an “on-grid” development, due to the extra costs of installing high-spec insulation and renewables. At current market rates, that could add £20-24,000 to the final price of a two-bedroom flat. The developers believe however that there is a high demand for this kind of home due to their rarity. The financing for the project is already in place and the project is expected to be financial viable.

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.

3D printing’s next trick: ears and skin

Filed under: Health, Technology — Tags: — Nicholas @ 11:10

In the gee-whiz world of 3D printing, the next new thing may well be printing skin:

Three-dimensional printing is a technique for making solid objects with devices not unlike a computer printer, building up line by line, and then vertically layer by layer.

While the approach works with polymers and plastics, the raw ingredients of 3D printing have been recently branching out significantly.

The printers have been co-opted even to make foods, and do-it-yourself biology experiments dubbed “garage biotech” — and has most recently been employed to repair a casting of Rodin’s sculpture The Thinker that was damaged in a botched robbery.

But at the annual meeting of the American Association for the Advancement of Science in Washington DC, the buzzword is bioprinting: using the same technique to artfully knock out new body parts.

QotD: Drink an imported beer and make Mother Gaia cry

Filed under: Environment, Quotations — Tags: , , , — Nicholas @ 10:46

According to PricewaterhouseCoopers partner and renewables specialist Michael Timar:

    “If someone saves money from having cavity wall insulation put into their house, but then spends it on something which produces carbon emissions in its manufacturing, or takes an extra journey, then the environmental benefit is lost.

    “You have to think about what the effect is all the way down the chain — that if you use less, you might actually end up consuming more.”

    Mr Timar warned that people who had saved £100 by cutting their energy bills could use the cash to fund extra leisure activities, such as drinking imported alcoholic beverages in bars — or electronic gadgets, which are often shipped from overseas.

This is beautiful:

    It has been calculated by environmental experts that one single bottle of imported beer uses 900g of CO2 — wiping out two-thirds of the annual carbon savings made by replacing all light bulbs in an average home with energy-saving models.

Drink two and you’re in credit.

Your Valentine’s Day date could be worse: you might be a male Anglerfish

More bits of mating lore from the animal kingdom here.

Pondering dinosaur sex on Valentine’s Day

Filed under: Randomness, Science — Tags: , — Nicholas @ 08:06

No, really:

I have been sitting here with two Stegosaurus models for 20 minutes now, and I just can’t figure it out. How did these dinosaurs — bristling with spikes and plates — go about making more dinosaurs without skewering each other?

Stegosaurus has become an icon of the mystery surrounding dinosaur sex. Dinosaurs must have mated, but just how they did so has puzzled paleontologists for more than 100 years. Lacking much hard evidence, scientists have come up with all kinds of speculations: In his 1906 paper describing Tyrannosaurus rex, for instance, paleontologist Henry Fairfield Osborn proposed that male tyrant dinosaurs used their minuscule arms for “grasping during copulation.” Others forwarded similar notions about the function of the thumb-spikes on Iguanodon hands. These ideas eventually fell out of favor — perhaps due to embarrassment as much as anything else — but the question remained. How can we study the sex lives of animals that have been dead for millions upon millions of years?

H/T to Maggie Koerth-Baker, who writes: “You’ve really got to read this entire article. Out loud. To someone you love. If they’re the kind of lover who wants to know about prehistoric mating rituals, the dino-sex theories of Victorian paleontologists, or how to sex a fossil, they’ll thank you. (And if they aren’t that kind of lover, well. Maybe it’s time to re-think the relationship.)”

The Netherlands go nuke, downplay wind power

Filed under: Economics, Environment, Europe, Technology — Tags: , , , , — Nicholas @ 09:50

Of all the EU states, the last one you’d expect to give up on wind power would be the one that everyone associates with windmills:

In a radical change of policy, the Netherlands is reducing its targets for renewable energy and slashing the subsidies for wind and solar power. It’s also given the green light for the country’s first new nuclear power plants for almost 40 years.

Why the change? Wind and solar subsidies are too expensive, the Financial Times Deutschland, reports.

Holland thus becomes the first country to abandon the EU-wide target of producing 20 per cent of its domestic power from renewables. This is a remarkable turnaround from a state that took the Kyoto Agreement seriously and chivvied other EU members into adopting renewable energy strategies. The FT reports that instead of the €4bn annual subsidy, it will be slashed to €1.5bn.

I did a quick Google image search for a typical Dutch windmill image, and decided that this one was too amusing to pass up:

QotD: (Historical) weather and climate

Filed under: Environment, History, Quotations — Tags: , , , — Nicholas @ 13:01

I read a lot of history and thus know a fair bit about how weather impact has been perceived by humans over time. It is a fact that the 20th century was an abnormally lucky hundred years, meteorologically speaking. The facts I managed to jam into tweets included (a) the superstorm that flooded 300 square miles of the Central Valley in California in the 1860s, (b) rainfall levels we’d consider drought conditions were normal in the U.S. Midwest before about 1905, and (c) storms of a violence we’d find hard to believe were commonly reported in the 1800s. I had specifically in mind something I learned from the book Wicked River: The Mississippi When It Last Ran Wild, which relays eyewitness accounts of thunderstorms so intense that travelers had to steeple their hands over their noses in order to breathe air instead of water; but a sense that storms of really theatrical violence were once common comes through in many other histories.

We had a quiet century geophysically as well — no earthquakes even nearly as bad as the New Madrid event of 1812, which broke windows as far north as Montreal. And no solar storms to compare with the Carrington Event of 1859, which seriously damaged the then-nascent telegraph infrastructure and if it recurred today would knock out power and telecomms so badly that we’d be years recovering and casualties would number in the hundreds of thousands, possibly the millions.

(I’m concentrating on 19th-century reports because those tended to be well-documented, but earlier records tell us it was the 20th century calm that was unusual, not the 19th-century violence.)

The awkward truth is that there are very large forces in play in the biosphere, and when they wander out of the ranges we’re adapted to, we suffer and die a lot and there really isn’t a great deal we can do about it; we don’t operate at the required energy scales. For that matter, I can think of several astronomical catastrophes that could be lurking just outside our light-cone only to wipe out all multicellular life on Earth next week. Reality is like that.

QotD: Genomics

Filed under: Health, Quotations, Science — Tags: , — Nicholas @ 00:07

There’s been enormous progress in genomics; we’re now on the threshold of truly understanding how little we understand. While the anticipated firehose of genome-based treatments hasn’t materialized, we now know why it hasn’t materialized, and it’s possible to start filling in the gaps in the map. Turns out that sequencing the human genome was merely the start. (It’s not a blueprint; it’s not even an algorithm for generating a human being. Rather, it’s like a snapshot of the static data structures embedded in an executing process. Debug that.) My bet is that we’re going to have to wait another decade. Then things are going to start to get very strange in medicine.

The Register: Let’s replace the discredited term “scientist” with “boffin”

Filed under: Media, Science — Tags: , — Nicholas @ 08:28

The Register, reacting to the decision by the Advertising Standards Authority to allow homeopaths and herbalists to be described as “scientists”, offers an alternative term:

We here at the Reg would like to offer as a new gold standard our use of the term “boffin” to replace the now officially discredited term “scientist” — which was already in our view unacceptably loosely applied, including as it did researchers in such fields as sports science, psychology etc.

A boffin, on these pages at least, will be a researcher whose work is based on hard sums and/or hard facts such as fossils, atomsmasher collisions etc. Statistics, especially ones gleaned by surveying students or counting up patents granted etc, will generally not count. Persons who work with the latter sorts of material will normally be known as eggheads, trick-cyclists, economists etc as appropriate.

And even though the word “scientist” now officially means nothing, we still aren’t going to apply it to homeopathic smellies experts.

Study implies that “traditional” parenting roles may be better for children

Filed under: Health — Tags: , , , — Nicholas @ 09:22

Cue the outrage:

Despite the long push for more equality in parenting duties, new research suggests that mothers and fathers may actually get along better when parenting roles are divided along more traditional lines — that is, when fathers back off caregiving duties, such as feeding and bathing, and put more effort into playtime.

[. . .]

Families in which fathers were more involved in play activities had more of what researchers called supportive interaction between the two parents.

In contrast, more of what is described by researchers as “undermining behaviour” was seen among families in which fathers do more of the caregiving.

[. . .]

It is unclear why the study yielded the results it did, but Sarah Schoppe-Sullivan, a professor of family science at Ohio State University and one of the study’s co-authors, suggested parents may be subconsciously bothered when parenting roles conflict with their pre-conceived ideas.

From the mother’s point of view, it could be a function of “maternal gatekeeping,” she said. “For mothers, maybe, it’s hard to give up some control to the father. That could be a total social effect, but there could some sort of biological underpinning to it.”

It’s a single study, so the results are hardly conclusive, but the general tenor of the study will not be popular in certain academic and political circles.
