How Effective is the iPad as a Business Tool?
Right from the start the iPad was marketed as one of the best unique devices to be launched on the market. It’s screen size and ability to render amazing images as well as it’s great video playback lives up to this claim. However, there is more to the iPad than just this because the device offers business-savvy users some very interesting apps they can really benefit from. Although Apple is pretty independent, it does however, have in-built support for Microsoft [...]
Obesity affects job prospects for women, study finds
ScienceDaily (Apr. 30, 2012) ? Obese women are more likely to be discriminated against when applying for jobs and receive lower starting salaries than their non-overweight colleagues, a new study has found.
The study, led by The University of Manchester and Monash University, Melbourne, and published in the International Journal of Obesity, examined whether a recently developed measure of anti-fat prejudice, the universal measure of bias (UMB), predicted actual obesity job discrimination. The researchers also assessed whether people's insecurity with their own bodies (body image) and conservative personalities such as, authoritarianism, and social dominance orientation were related to obesity discrimination, as they are related to homophobia and racism.
Psychologist and lead researcher Dr Kerry O'Brien said the nature of the study was initially concealed from the participants to avoid biased results, and simply advertised as a study on whether some people are better at personnel selection than others.
"Participants viewed a series of resumes that had a small photo of the job applicant attached, and were asked to make ratings of the applicants suitability, starting salary, and employability," said Dr O'Brien. "We used pictures of women pre- and post-bariatric surgery, and varied whether participants saw either a resume, amongst many, that had a picture of an obese female (BMI 38-41) attached, or the same female but in a normal weight range (BMI 22-24) following bariatric surgery.
"We found that strong obesity discrimination was displayed across all job selection criteria, such as starting salary, leadership potential, and likelihood of selecting an obese candidate for the job."
The higher a participant's score on the measure of anti-fat prejudice, the more likely they were to discriminate against obese candidates, while those with a more authoritarian personality also displayed discrimination.
Dr O'Brien and co-authors Dr Janet Latner, from the University of Hawaii, and Dr Jackie Hunter, from Otago University, noted that one of the particularly interesting and new findings was that the participants' ratings of their own physical appearance (body image) and importance of physical appearance were also associated with obesity discrimination.
"The higher participants rated their own physical attractiveness and the importance of physical appearance, the greater the prejudice and discrimination," said Dr O'Brien. "One interpretation of this finding might be that we feel better about our own bodies if we compare ourselves and discriminate against 'fat' people, but we need to test this experimentally."
The study is the first to show a relationship between explicit self-report measures of obesity prejudice and obesity job discrimination. In addition, the results suggest that a belief in the superiority of some individuals over others is related to the perception that obese individuals deserve fewer privileges and opportunities than non-fat individuals.
Dr O'Brien added: "Our findings show that there is a clear need to address obesity discrimination, particularly against females who tend to bear the brunt of anti-fat prejudice. Prejudice reduction interventions and policies need to be developed. It's also becoming clear that the reasons for this prejudice appear to be related to our personalities, how we feel about ourselves, with attributions, such as, obese people are lazy, gluttonous etc merely acting as justifications for our prejudice."

Australia Parliament investigating why Apple?s digital goods cost more down under
The standing committee on infrastructure and communications in the Australian House of Representatives will be launching an investigation into why digital goods (such as iTunes music and iBooks) are priced so much more highly in Australia than elsewhere in the world. Traditionally, shipping costs drove prices up for physical goods, but for electronic files you're downloading, there's really no good reason for such a price disparity.

Highs, lows of Ferguson's career
Is Sir Alex Ferguson the most successful manager of all time?
If he?s not sitting at the head of the table, he?s surely got a place there, right?
Writing for Forbes, Bobby McMahon reminds us that Ferguson wasn?t born into the Manchester United position (even if it seems that way.) His journey to Old Trafford was shaped through failures as well as successes ? the same way most of us have success and failures in life.
McMahon also says Ferguson was a pretty decent player in his day.
The lengthy piece finishes with something that might be called the ?Seven Habits of Highly Effective Managers, Sir Alex Ferguson Version.? Like this one:
He has a hunger for knowledge. It has not only kept him relevant to a sport and a business that has changed beyond recognition but has kept him at the top.

A Most Peculiar Sunset
NASA/JPL-Caltech
You wouldn't know it, not right away, but there is something strange about this picture. It's a sunset, yes, but notice the blush of color right above the sun. It's blue. And as you look up, the blue fades into a faint rose or pink.
Now think about the sunsets you've seen, how often the sky can turn golden, or orange, sometimes pink, red, but when you look up, away from the setting sun, those colors fade back to a pale, twilight blue? It's rare to see a sunset dipped in blue.
So this photo is a puzzle: it's blue where the red should be and red where the blue should be. Why?
Because we're not on Earth. This is a Martian sunset. On May 19, 2005, the camera on NASA's little robot, the rover named Spirit, took this picture while sitting in the Gusev crater on Mars. NASA snapped the photo, says the press release, "around 6:07 in the evening of the Rover's 489th Martian day."
NASA/JPL-Caltech
Apparently, Mars has blue sunsets all the time. Earth doesn't.
NASA admits that there's a color filter on Spirit's camera that exaggerates the colors slightly, but they say the blues you see here "are similar to what a human would see" on Mars. Not so much the pinks. Pinks are slightly more pronounced in these photos, but the blues are true colors.
So here's our question: Why are Martian sunsets blue?
The Air On Mars Is Different From The Air On Earth
On Earth, the air is mostly nitrogen and oxygen. We've also got moisture, dust particles, smoke, aerosols, pollen, salt from the ocean. The atmosphere on Earth is denser ? meaning there are more molecules per cubic inch in our air.
Martian air, by contrast, is much, much thinner, about 1percent the density of air on Earth, plus the gasses are different: they've got CO2, nitrogen and argon, but most important, says Mark Lemmon, associate professor of planetary sciences at Texas A&M University, air on Mars is rich with teeny, teeny particles of dust. Their dust is smaller than our dust, and they've got more of it in the Martian sky. Dust is the key to why the two sunsets look different, so we'll be keeping our eye on Martian dust.

Light Scatters Differently On Mars Than It Does On Earth
Let's stand facing the sun on Mars. It's early evening. The sun is setting. Light is streaming toward our eyes, moving through the dusty air. What happens?
Sunshine, as you know, contains many different wavelengths of light. If you catch a beam of light in a prism (Newton did this) it breaks into a rainbow of colors ? reds, violets, blues. When the sunshine on Mars hits the clouds of fine dust floating through the air, it also breaks into different colors. Martian dust is exactly the right size to absorb the blue wavelengths of light and scatter red wavelengths all over the sky. That's why if you are standing on Mars and look away from the setting sun, most of the sky is rosy, pink, and various shades of red.
But now look straight at the setting sun. On Mars, the beams of light streaming toward you, having lost their red waves, show the wavelengths that haven't scattered off. That remaining light is predominantly blue. So when you look straight at the sun on Mars, you see a haze of blue. Look away from the sun, and the light is red.
It's exactly the opposite on Earth.
Here, when the sunshine hits our atmosphere, the waves that scatter are blue in color. That's why everywhere we look, our sky is blue ? except when we look straight at the setting sun. There, the blue light is missing, so the remaining wavelengths predominate, and they are mostly the reds, the golds, the oranges.
Our atmosphere scatters blue; Mars' atmosphere scatters red.
Our sunsets feature reds. Mars' sunsets feature blue.
That's because our air is different from Martian air.
What About That Blue Halo Around The Sun?
Take a look at this short animation from NASA. Called "I'm Dreaming of A Blue Sunset," It's a reconstruction from still photographs, where you can see a bright blue halo around the sun as it sinks to the horizon. Why is that halo there?
According to Professor Lemmon, when sunshine hits Martian dust, the blue light doesn't bounce far. It sticks near the dust, pingponging around at close range. That's why if there's a dust storm on the horizon, (and that's what seems to be happening in the video), the area around the sun traps a lot of blue light, and the sun seems to glow blue.
Red light, as we've said, ricochets much farther off, so in the video, the reddish patches are some distance from the sun, the blue is tucked in close.
The point being, if you happen to be camping out on Mars and see an intense blue sunset like the one in the video, make sure the wind isn't blowing in your direction, because a few hours from now, that sandstorm might blow your tent down. (You did remember to bring a tent, no?)
