Forecasting with a CGE model: does it work?
Computable general equilibrium models can be used to generate detailed forecasts of output growth for commodities/industries. The main objective is to provide realistic baselines from which to calculate the effects of policy changes. In this paper, we assess a CGE forecasting method that has been applied in policy analyses in the U.S. and Australia. Using data available up to 1998, we apply the method with the USAGE model to generate "genuine forecasts" for 500 U.S. commodities/industries for the period 1998 to 2005. We then compare these forecasts with actual outcomes and with alternate forecasts derived as extrapolated trends from 1992 to 1998.

NEW YORK, Oct. 10 (UPI) -- A federal judge has ruled New York City's human rights law does not protect unpaid interns from sexual harassment.
U.S. District Judge Kevin Castel dismissed a lawsuit brought by Lihuan Wang, a former intern at the Chinese-language Phoenix Satellite Television US, the New York Post reported. Castel found that Wang, because she was not paid, was not a Phoenix employee.
Wang, who is now back in China, became a Phoenix intern in 2010. In her lawsuit, she said that Zhengzhu Liu groped her after inviting her to his hotel room to talk about possible paid employment at Phoenix.
Liu invited Wang to stay with him at a hotel in Atlantic City, N.J., when she asked him months later about her future, she said.
Phoenix investigated Wang's story and dismissed Liu last year, the Post said.
Castel did not dismiss another part of Wang's lawsuit. She is seeking damages from Phoenix because she was not hired while the company says she never applied.
Wang's lawyer said part of the suit may be transferred to Washington where suits brought by other Phoenix interns may be heard.
Lawsuits by unpaid interns have become common recently. In many of them, interns argue they are treated like employees -- except for the paycheck.

Youth Suspected of Stabbing Givatyaim Teen Over a Cigarette
According to witness, suspect attacked 18-year-old after skirmish over victim's refusal to give him a cigarette.
Police on Wednesday arrested a teenager suspected of stabbing an 18-year-old resident of Givatayim, after the victim refused his request for a cigarette.
The victim was evacuated to Tel Hashomer Hospital in stable condition, with serious wounds to his chest.
Police opened a search for the assailant shortly after the incident and managed to locate him within half an hour, attempting to flee the city on his motorcycle. The 17-year-old suspect was detained for further questioning.
According to eyewitness reports, the incident occurred after a skirmish broke out between a group of immigrant and local teenagers.
A friend of the victim, 'Max', told reporters that they had been approached by a group of boys while sitting on a bench in the city,
"We sat in the park drinking [and] on the way home stopped to rest on a bench," he said. "Suddenly, a group of guys came up and one of them asked for a cigarette."
"We told him no, because we didn't have any, and he answered that he was going to search us," added the witness. "It all happened very fast but suddenly I saw my friend walking toward me with blood on his chest. I jumped on him and put pressure on his chest in order to stop the bleeding."
As he told his testimony, Max's hand was still covered in his friend's blood.
In the wake of the attack, Givatayim Mayor Reuven Ben Shachar ordered municipal security forces to keep close watch on groups of teenagers gathering in the city park to drink.
"We will not allow violence in Givatayim," he declared. "This is a city unaccustomed to incidences such as these. Anyone who thinks he can go around Givatayim with a knife and alcohol is gravely mistaken."
"We will not allow this to happen and we will protect the quiet character of this city at any price," Ben Shachar added.
The mayor is planning to hold a special discussion session on the issue of youth violence later Wednesday.

Arthur Scott King was an American physicist and astrophysicist.
He was born in Jerseyville, Illinois, the son of Robert Andrew and Miriam Munson King. In 1883 the family moved to Santa Rosa, California in an attempt to alleviate their son Arthur's chronic asthma. The asthma cleared up, and in 1890 they moved again to Fresno.
In 1895 Arthur graduated from Fresno High School, then attended the University of California, Berkeley. He developed an interest in physics, and in 1899 he was admitted into their graduate school. He was awarded a Ph.D. in 1903, the first ever Ph.D. in physics awarded by that university.
After winning a Whiting Fellowship, he spent two years in Germany, studying at Bonn and Berlin and travelling in Europe. His academic interests were focused on spectroscopy, and at the time these institutions were leaders in the field.
In 1905 he returned to Berkeley and became an instructor. The following year he married Louise Burnett, and the couple would have two sons. The same year he published a paper describing the use of an electric furnace for use in spectroscopy.
He was offered a position at Mt. Wilson Observatory in 1907, and took his leave from Berkeley. He spent much of the remainder of his career studying the spectra of elements and molecules, with particular focus on rare earth elements. He also performed studies of meteors, including their spectra and directional paths. In 1929, he collaborated with Dr. Raymond T. Birge to discover the isotope Carbon-13, based on differences in the spectrum.

BAGHDAD — Thousands of mourners marched through Baghdad behind the coffin of one of the country's most powerful Shiite leaders yesterday, and eulogies from rivals and allies reflected deep worry over the political void left by his death.
Abdul-Aziz al-Hakim's death from lung cancer comes at a time of disarray among Iraqi Shiites. Just this week, his party formed a new political grouping to contest January's parliamentary elections that excludes the Iraqi prime minister, setting up a showdown between the two former allies.
Rivalries were put aside as al-Hakim's body was flown back to Iraq from Iran, where he died Wednesday, but tensions were clear as he was remembered in memorial services.
"We have lost you while we are undergoing a delicate and sensitive period, and in a time when we are in need of strong men with experience and who have made great sacrifices," Prime Minister Nouri al-Maliki said at the airport upon the arrival of al-Hakim's coffin. "We are still confronting the remnants of a dictatorship and terrorism by those who want to hurt Iraq."
Islamic tradition usually requires the dead to be buried swiftly, preferably within hours. But political factors were at play in the case of al-Hakim — one of Iraq's most influential power brokers — and his body was taken on a three-day mourning tour starting with memorials Thursday in Iran and ending with burial today in the Shiite holy city of Najaf in southern Iraq.
Iraq is holding parliamentary elections on Jan. 16 in which competition over the Shiite vote will be stiff because of the split among Shiite parties. In regional elections this year, al-Hakim's party, the Supreme Islamic Iraqi Council, did poorly in many parts of the south. A show of masses of supporters turning out to mourn al-Hakim could boost the party, and the bloc it formed this week with other parties called the Iraqi National Alliance.
Al-Hakim, who died at the age of 59, was a symbol for many of the re-emergence of Iraq's Shiite political majority after decades of oppression under Saddam Hussein's Sunni-led regime. He worked with Americans after the 2003 U.S.-led invasion even while maintaining his ties to Iran, where he lived in exile for 20 years.
His death comes as insurgents have stepped up attacks, including coordinated bombings last week against government ministries in Baghdad that claimed about 100 lives. Security was tight in the capital yesterday, and many major roads were closed.

From the Royal Institution in London, DemoJam. Featuring designer of particle accelerators, Suzie Sheehy. Vision researcher and engineering lecturer, Ben Craven. Protein crystallographer, Stephen Curry. The UK's coolest science teacher, Jonny Berliner. And your host, formerly the UK's coolest teacher, now stand-up mathematician, Matt Parker.
Are we done? We're done. All right. Now, ever since we had DemoJam, well, this means the Royal Institution is no longer just for Christmas. Lectures? Oh, no. No, no. We've invited our favourite scientists from right across the country to come in, flop their favourite demos out on the table, amaze us, educate us. Whatever they're going to do, it's going to be thoroughly good, geeky fun. And to start us off, can we please put our hands together for our very first DemoJammer, Dr. Suzie Sheehy.
You would have seen one of these Van de Graaff generators when you were at school. But if your school was anything like mine, then once a year, the thing got hauled out, switched on, and absolutely nothing happened. Now, what's supposed to happen is that the belt peels electrons off the rollers, and it builds up a positive static charge on the top of the dome.
I've got a bunch of electrodes which are hooked up to the Van de Graff. And when I switch it on, every other electrode will become positively charged. And the rest of them will stay at ground, or zero volts.
And my particle today is a ping pong ball which I've covered with a metallic paint so it can hold a charge. And when that sits on one of the positive electrodes, it becomes positively charged itself. And you should have learned, around about the Van de Graaff lesson in school, that like charges repel. So it actually pushes away from the positive electrode. And then, when it sits on the ground electrode, it loses all of that charge and becomes neutral again.
But it keeps rolling across to the next positive electrode, and the cycle repeats again. And each time this happens, it gains a little bit of momentum. So it gets faster and faster and faster, if the Van de Graaff works. So, if you'll all do me a favour and just kind of will it on with all of your will power, I'll just switch it on.
It's all right. You can breathe again now.
Now, it turns out, you can't roll protons around in a salad bowl, unfortunately. You need to actually put them in an ultra-high vacuum and then use magnetic fields to actually bend them around in a circle.
Now, it also turns out that a real proton is about 200 trillion times smaller than a ping pong ball. And it can't change its charge. So we've made a bit of a cheat here, because we've kept the electric field constant.
In a real accelerator, you have to change the electric field to keep accelerating the particle around. And you have to do it pretty quickly. Because the protons in the Large Hadron Collider, well, they're traveling at just a tiny fraction below the speed of light. And the speed of light is 299,792,458 meters a second.
So, keeping that in time with increasing speed of the particles is pretty tricky. And we're not just talking about one particle. We actually accelerate billions or even trillions of them all at the same time. And they all have the same electric charge, so they all try and repel against each other. And trust me, that causes all sorts of other problems.
So, as models go, this one is a little bit simplified. But there's two things about real accelerators that this can actually show us.
The first one is looking at the shape of the bowl, the curved shape, that's actually quite similar to the way we shape the magnetic field in the type of accelerator that I work on. And if you guys want to google it later, it's called a Nonlinear Non-scaling Fixed-Field Alternating Gradient Accelerator.
Now the other thing which relates to real particle accelerators is the power source. Accelerators based on this Van de Graaff principle were actually the cornerstone of nuclear physics research for decades. And my first publication, which was in nuclear physics, used a Van de Graaff accelerator. So to me, the Van de Graaff isn't just an unreliable, useless classroom demonstration. It's a reminder of how the development of particle accelerator technology has fundamentally changed the way that we understand the world around us.
Ladies and gentlemen, Dr. Suzie Sheehy! [APPLAUSE] That's fantastic. We give you the Small Hadron colander.
Now, if you're at home watching this from the comfort of your own computer, you might think that DemoJam, well, you think it's a short, concise, fun evening. Oh, no. It's not. We just edit it to make it look like it's short and fun. In reality, the show takes lots of long, tedious breaks while we set up for the next shot.
So to avoid the audience becoming too, well, irate, we give them some busy work. We're going to issue everyone with two Styrofoam cups and some elastic bands, and we'll come back later in the show to see what they're going to make of them. Now, however, can we get ready for our next DemoJammer. Put your hands together for Dr. Ben Craven. [MUSIC PLAYS]
In a moment, down here, I'm going to show you a little square. And what I want you to do is to tell me, in one word, your first impression, what colour that square is. So here goes. Call it out.
OK. So you think that one's white. Well how about this one?
White. Even whiter. So maybe the first one is not as white as you thought it was. Well, if that second one is white, look at that one. Okay. That's really white. And so white that we're having to adjust the camera to take account of it. So, do you think that third one is definitely white?
Are you absolutely certain it's white? Well, look. There's the white one. Now, see this first one you were looking at. What color do you think that is now?
It's grey, right? Let's take the lights up and see what it really is. What colour is it? Black. Now, a couple of minutes ago, you were telling me that that was white. Now you're telling me that it's black. So let's see what's going on. Let's have the lights back, please.
I was actually giving your brain a very, very difficult task to do here. This square is emitting a certain amount of light into your eye. Now you're in a dark room, and this is probably the brightest thing you can see. And so, your brain made the perfectly reasonable guess that this was a light thing in a dark place. But what the visual part of your brain didn't know about was the very bright light inside the box. And what it was actually looking at was a piece of wood painted black in a very bright place.
I'm going to do a little survey now. Has anybody seen this effect before, this demonstration? A handful of people have. Most of you haven't.
Well I'm sorry to say that most of you are completely wrong, because you've seen it hundreds of times before. When you look up at the moon in the sky, it feels like you're looking at a light object, a light-coloured object. We make jokes about the moon being made of cheese.
In fact, if I had a piece of moon rock here, it would be dark. It would be something like the surface of a road or a piece of dark slate. When you look at the moon, you're not looking at a light object in a dark place. You're looking at a dark object in a very bright place. Because the sun is shining very brightly on the moon.
So next time you look up at the moon in the sky, I want you to try and convince yourself that you really are looking at a dark object in a bright place. I've been trying for years, and I've never succeeded. So I hope you'll have better luck than I do. Thank you. [APPLAUSE] [MUSIC PLAYS]
Wow, that really is mind boggling. And, actually, do you mind if we have a look? if you come in here, right, you can see. It really is that there's a bathroom light and then just some poorly painted bits of wood. That is absolutely brilliant. And thankfully, because of this bit of equipment, we now finally have scientific proof of the Jackson conjecture, which states, it don't matter if you're black or white or some kind of intermediate stage.
Anyway. Now DemoJam would like to welcome along Professor Stephen Curry for a little fireside chat. [APPLAUSE] [MUSIC PLAYS] For which I need to be over there.
And now I'm over here. I'm joined by Professor Stephen Curry, who is a structural biologist. And you work on the somewhat dangerous foot and mouth virus.
Yes. That's right.
And that does sound very dangerous. Do you actually get to use the virus?
No, I work in a laboratory in London. We are not allowed, by law, to use the virus because it's so contagious. And we only work on small fragments from the virus.
So you get, like, a little bit?
We do, yes.
Like, just the foot?
Not quite the foot, but we work on proteins that the virus makes inside the cell during the course of infection.
OK, OK. So you get a safe bit to look at.
It's entirely safe.
You've brought in a virus. And we couldn't bring in foot and mouth, I'm afraid. But here we have, now, who is this guy?
Well, this is actually a kissing cousin of foot and mouth disease virus. This is actually the human rhino virus, which causes the common cold.
That's the common cold. Right. Now, how accurate is this model?
Well, this is a child's toy. So it's not entirely accurate. The real virus has no eyes, is not covered in soft blue fur.
It's nowhere near as adorable.
I'm afraid not.
But it is still an educational aid to some extent, right?
It is. There is one feature which is quite anatomically correct. And that you can see on this end of the virus, which is that it has a five-fold symmetry axis, which means that if we rotate it 1/5 of a turn, then the virus looks the same.
How do we actually know any of that? I mean, how do we know it's shaped like an icosahedron?
Well, that's a good question. Because this toy is actually quite a bit bigger than the real thing. In fact, it's about 3 million times larger than a real rhino virus.
That's not bad. That's better than the proton we had.
Indeed. But even so, it's too small to see by eye, and it's too small even to see with our very best light microscopes. You can get a fuzzy image with an electron microscope, but if you really want to see the atomic details, which is what I'm interested in, then you have to use a technique called X-ray crystallography. And for X-ray crystallography, you need X-rays and you need a crystal. I happen to have a crystal -
It's all there in the title...
- here. Oh, yes. So, this is a crystal of quartz. So it's not a crystal of rhino virus. You are all perfectly safe. And what's interesting about a crystal is that inside the crystal, all the atoms are lined up in orderly rows.
But the virus is not a cuddly toy, but it's not a crystal either, is it?
No, it's not. But if we grow up a few milligrams of rhino virus, there are techniques which will allow us to induce them to stick together in an orderly form that makes a crystal of rhino viruses.
Right, so you get crystallized virus.
And then the fun begins.
Yes. So, a crystallized rhino virus would actually be an awful lot smaller than this. But the interesting thing about the crystalline form of matter is that if you shine X-rays through it, then it diffracts that X-ray off in hundreds of different directions.
So you put X-rays through the lattice. They get diffracted. And you get your diffraction pattern, over on a screen or something.
That's right.
And then, that's not a picture of the structure, but you can work back, I believe, mathematically, from the structure that you see here to the atoms that must have caused that.
Yes, that's right. So, we get spots on a detector. But in those spots is all the information we need, thanks to Fourier's transform, to reconstruct -
I'm a big fan.
- To reconstruct the structure of the virus. And what's interesting about that is that Fourier was a French mathematician from the nineteenth century. He died, unfortunately, before the X-ray was even discovered, before the virus was even discovered.
Why was he doing it?
Because he was interested in the transport of heat. He was interested in how fast does it take heat to get from one end of a hot poker to the other?
Hot poker research. Right, now. You do all this. You do the X-ray diffraction. You work back. You get the structure. Now, I assume we're using that to somehow combat these viruses.
Yes. So, if we can see the detail structure, so the results we get are much more detailed than this. We can see where every atom is in the virus, and that gives us a really detailed understanding of how the virus interacts with the cell, how it uncoats, and the things that it does inside a cell to cause infection. So if you understand how the virus works, then it gives you a way to develop drugs in order to stop it.
So why have we not got a cure to the common cold?
Well, the common cold, fortunately for us, isn't a terribly serious disease -
It is for me.
- By the time you develop symptoms, you're more or less halfway on the way to a cure.
So you're going to get better anyway.
That's right, yes.
So all we get from knowing the structure of the common cold viruses is we can make slightly accurate toys. So if I -
You could say that, yes.
If you get ill, you can curl up in bed and cuddle the virus that is currently infecting you. That's just great. Anyway, all the best with foot and mouth, which is a great sentence. Can we have a final round of applause for Stephen Curry? [APPLAUSE]
Right. Now that we're pretty much at the end of DemoJam, we should check back in with our audience to see what they did with those cups. So they all have made Bernoulli cups out of them. So let's see how this goes.
Spectacular, it turns out. If you're wondering how to make your own Bernoulli cup at home, then beneath me somewhere is an information box which you've already clicked. You can find out how to build your own, successfully.
However, given that this is the scientific process, we need to end properly with a conclusion. And because we are the Royal Institution here, we should do it in an orthodox, scientifically accurate method. Which is, of course, through song. Ladies and gentleman, Jonny Berliner.
[MUSIC BEGINS] When I look at the world, it's all black and white. Like the black of the sky and the white of the moon at night. But it's more than the wavelength of the ray that gives me sight. It's the way that my brain interprets the light. But the colour of the moon's not black or white. It's in between. And it's a matter of psychology why it couldn't be seen.
It couldn't be seen. It couldn't be seen. No, the colour of the moon, it couldn't be seen.
I got a cold. It hurt a lot. I wanted to see the rhino virus that was causing the snot. Looked under a microscope. Nothing to see. So I tried my hand at crystallography. Got a pattern of dots. Didn't know what they mean without Fourier analysis, the icosahedron couldn't be seen.
It couldn't be seen. It couldn't be seen. No, the icosahedral structure of the rhino virus, it couldn't be seen.
Now Mr. Van de Graaff would be overjoyed to see his machine spin a ping pong ball around a custom blown acrylic oblate spheroid. He'd be even happier that his technology can generate the protons for the LHC. That we accelerate and collide with energy and find fundamental particles that couldn't be seen.
They couldn't be seen. They couldn't be seen. No, the fundamental particles, they couldn't be seen. They couldn't be seen. They couldn't be seen. They couldn't be seen.
Jonny Berliner! And that, ladies and gentlemen, is DemoJam.

Touchscreen monitors are slowly starting to appear as Windows 7 uptake increases which has compatibility out the box. But while most displays have multi-touch capabilities this is usually restricted to a couple of fingers. 3M has announced it is going well beyond that limitation and creating a display that will recognize all ten digits.
The M2256PW is a 22″ screen that can detect up to ten fingers. It does this through the use of 3M's Projected Capacitive Technology which gives it a high level of accuracy. It has a touch response time of below 15ms for every finger allowing for a very smooth and responsive experience.
The video above is an old demonstration of the tech, but new videos do exist on the 3M website.
In terms of the actual display it has everything you would expect from a standard screen including a resolution of 1600 x 1050, DVI and VGA connections, and an anti-glare surface. Compatibility is with Windows 7 without additional drivers and can be made to work with Linux, Windows Vista, and XP.
A 19″ version of the display is available as a development kit, but no release date or price for the commercial 22″ version has been announced yet.

Matthew's Opinion
If you are going to invest in a touchscreen display then having support for all ten of your fingers is the best solution. It means you will never reach a point where you want to do more with your hands, but are restricted by the input.
I'm sure 3M intend this for business use as much as for consumers. No doubt the displays can be setup for a couple of people to use in a business environment possibly to control other devices or collaborate on a task. For that reason they will no doubt carry a premium price.
This isn't the first ten-finger touchscreen we have seen as Stantum gave a demo of its display late last year. With these mutli-touch screens appearing I doubt it will take long for ten fingers to become the expected norm on any touchscreen you buy.

The special character of the instrument is indicated by the next significant credit, Mr. Heloya Ishikawa, the piano technician specially assigned to the EX by the Kawai factory, who accompanied it to Las Vegas to insure that it was set up flawlessly. He seems to have accomplished that mission admirably. Finally, engineer John Kiehl recorded, mixed, mastered and co-produced the performance, and created one of the best sounding piano recordings I've heard in the process.
None of that would matter so much, of course, if the performance itself wasn't as masterful as the instrument and technicians. Mike Jones became enamored of the piano listening to his parents Oscar Peterson albums as a child, and when his childhood idol recommended Boston's Berklee College Of Music as an appropriate place to develop his craft, Jones was on his way. While at Berklee, he became an acolyte of Dave McKenna's formidable left hand technique. Combining that rock solid foundation with his emulation of Peterson's right hand pyrotechnics produced a result that ranges from excellent to astonishing. That range is on full display on the eleven tracks of this release.
When I played this one for the piano player in my house, she just kept shaking her head and saying "Do you know how hard that is to do?" Well, as a matter of fact, I don't. I'm a string player, myself, and all keyboard parts sound hard enough. I do know how good it sounds, though, and it sounds spectacular. There are plenty of peaks, but they're hard to single out because the valleys are very shallow. There's not a misplaced note or an unsatisfying moment to be found. This is very simply the best solo piano performance I've heard this year, and rivals any I've ever heard. It's not to be missed.

Father and son 'to enjoy family activity holiday in Andorra'
The sights and sounds travellers can expect to find in the Pyrenees on a family activity holiday to Andorra are set to be experienced by a father and son.
Dad Phil Hibbert is taking 18-year-old Paul to the mountain range to tackle a gruelling 450-mile bike ride, reports the Shetland News.
Phil, from Vidlin, has become a keen cyclist since developing a sight condition known as uveitis.
The ailment means he cannot legally drive, meaning his bike has become his primary method of transport.
Speaking about how the condition has not slowed down his lust for life, Phil said: "Nowadays there is a tremendous amount that can be done to make the most out of the reduced vision some people experience from a number of conditions."
Those looking to tread a similar path in the Pyrenees could opt for The Adventure Company's Active Pyrenees Family Holiday.
In addition to mountain biking and hiking, the trip allows travellers to explore the Siscarro Lakes and Incles Valley.
If this article sparks your imagination then have a look at our activity holidays or our late availability holidays page
We've over 250 adventures worldwide & take 10,000 travellers away annually. We've been operating over 15 years & pioneered the concept of family adventures.
We go on most of our holidays so can offer excellent firsthand advice. Last year 90% of passengers rated our trip 'excellent' or 'good'

Bad Rabbits Talk "American Love"
Wed, 20 Mar 2013 10:11:01

Bad Rabbits Videos
Bad Rabbits are the musical revolution that the world's been waiting on.
The Boston quintet treads a fine line between sexy R&B swag, rock 'n' roll soul, and alternative metal crunch. It's a delicate balance unlike anything currently out there or preceding the group. In a day and age where everybody is derivative of something else, Bad Rabbits stand alone. That's why they could very well change the game for good when their new album American Love drops on May 14.
While gearing up to hit the road with Kendrick Lamar and Steve Aoki, bassist Graham Masser spoke to ARTISTdirect.com editor in chief Rick Florino about American Love and so much more in this exclusive interview.
What's the vibe like when you guys are recording?
We definitely have a couple of different ways in which we write. For American Love, we wrote with a producer B. Lewis. He lived in Oakland so he'd send us some ideas. We'd write a track over it or record ideas and send them back. We'd collaborate that way. It was a little different for us. The best way we worked was to be in a room together. That's the most direct. Usually, it'll just start with someone having an idea. We'll be messing around, and I'll have a bass idea or "Dua" will have a vocal melody or Sheel will have a drum part. It stems from there. It's an organic process. It comes from that one little idea. Someone hears it and says, "Oh, that's cool!" Then, they add something to it. It forms from the bottom like that into a song.
You can hear all of those nuances when you listen to American Love on headphones.
B. Lewis added another element to the album. That's why we brought him on. He had his own unique style, and it fit really well with us. Between the five of us and him, everyone is very passionate about the songwriting and recording processes. To me, that's where everything stems from in terms of the band, the brand, and the business. We want to make those recordings as good as possible. We have so many ideas we tend to throw at the songs. We just have to chip away at them to make them more cohesive.
What's the story behind "Royal Flush"?
It's a little different from the rest of the stuff on there. It started with a demo B. Lewis sent us. Immediately, everyone really liked it. The vocal melodies are really striking. It's a unique song. It showcases a little bit of the hardcore rock elements of our band. It brings a little bit of the live element to the record. Everyone really liked it. We worked hard on honing in on those melodies and making it a captivating song. We worked on the ending to make it very powerful and epic. It's like "Can't Back Down" off of our Stick Up Kids EP. It had that ending with a triumphant feel. Once we had it done, we were like, "This sounds like the end to an album".
How did "Sayonara" come together?
It was a similar process. A lot of tracks stemmed from our ideas. To me, that one was the best example of the fusion of R&B and rock. It starts with this epic post-rock ambient intro. Then, it breaks into the verse which is a more smoothed-out R&B sound. It really captures the duality of our music.
How important is that heavy element to the music?
It's not something we contrived like, "We don't want to be just an R&B band so let's put a breakdown here". It's not like that. Personally, I grew up listening to a lot of punk rock in middle school and high school. My first band was a punk band. I went to a lot of those shows. That dynamic of a live show having a very aggressive influence in the music was something I've been listening to for a long time. At the same time, my parents raised me on Sly & the Family Stone, Marvin Gaye, Stevie Wonder, and Michael Jackson. I listened to a lot of Motown and soul at home. When I was hanging out with my friends in eighth and ninth grade, we started a punk band, and we went to shows at The Wetlands and Coney Island High. It's a natural thing for us. Sheel, Salim, and Dua really came from hardcore roots. They played in hardcore, metal, and rock bands. That's part of them. We all had similar suburban upbringings playing in garage bands with our friends. A lot of that carries over. My parents played a lot of Motown and soul. Dua grew up singing in the church. His parents played gospel for him. We all had a lot of those dual influences.
What heavy bands did you guys bond over?
I always listened to bands like Rancid, NOFX, and Less Than Jake—a little bit more on the punk tip. Dua, Salim, and Sheel love Deftones and GlassJaw. Those were big ones. Then, there's Pantera. Bad Brains is a band we all listened to.
What song speaks to you the most right now?
I really like "We Can Roll". It's a cohesive fusion of rock and R&B. The melodies are rooted in R&B, but you can hear the crunchy guitars and heavy drums over them. It's the most unique, to me.
If you were to compare American Love to a movie or a combination of movies, what would you compare it to?
We've always seen ourselves as the party band in PCU. Our goal has always been to be P-Funk in the new PCU [Laughs]. That still holds true for American Love. It's still a party record, but it's got the love story where the kid meets the girl. It's a party record, it's a love record, and it's a fun record.

Recently, I was approached by a company to write about a product on my blog. I found out that I did not fit their criteria, and that really bugged me since they wanted to work on a viral advertising method to promote the product.
Their criteria were very strict, and so I was disappointed. When we were talking about it, they made no mention of needing me to be positive about the product, but they probably would not try to do such a thing with a product that has not tested well before.
I think such things are going to become more prominent with larger and smaller bloggers in the blogosphere as companies look for cheap and effective advertising, and in my mind, word of mouth is some of the best advertising a company can get. Impress a few key people, and you can sway the opinion of many.
This does not mean that I think you should hide the fact that you were approached to write about such product. I think being honest with your audience is the best thing you can do to retain your journalistic integrity. Some people try to hide that the article they wrote was in a way sponsored by a company or service, and I think this is a sad way to run a blog, and a fast way to ruin one.
If you are approached by a company to write a post on a product, be as objective as you can, and don't just turn it down because if you approach it correctly, you won't be doing anything wrong according to me.
What do you think though? Can you trust a blogger that has gone ahead, tested a product and written about it on his site?
