Wichita State upsets OSU 70-66 for Final Four trip

LOS ANGELES (AP) ? Cleanthony Early kept stealing glances down at the hat in his hands while he waited for his turn to climb the stepladder. The Wichita State forward seemed stunned at the words on the side of his brand-new ballcap: "Final Four Atlanta."

"It's crazy. I still can't believe we're here," Early said. "You try to expect it, but you expect a lot of things that don't happen. This really happened."

Believe it. Wichita State is going to Atlanta, and these Shockers are no longer a surprise after the way the tenacious ninth seeds held off mighty Ohio State in the West Regional final.

Malcolm Armstead scored 14 points, Fred Van Vleet bounced in a big basket with 1 minute left, and Wichita State earned its first trip to the Final Four since 1965 with a 70-66 victory over the Buckeyes on Saturday.

Van Vleet scored 12 points as the Shockers (30-8) followed up last week's win over top-ranked Gonzaga with a nail-biting victory over the second-seeded Buckeyes (29-8), whose 11-game winning streak ended one short of their second straight Final Four. Wichita State's 20-point lead in the second half dwindled to three in the final minutes, but several Shockers stepped up with big plays to stop the surge, heeding coach Gregg Marshall's halftime command to "play angry."

All that anger turned into a joyous postgame party at midcourt, even though the Shockers realize they've got more work to do.

"I don't think we're Cinderella at all," Marshall said. "Cinderellas usually are done by this stage. If you get to this point, you can win the whole thing. You beat a No. 1 seed and a No. 2 seed ? I don't think Cinderella just found one glass slipper. I think she found four."

Wichita State is just the fifth team seeded ninth or higher to reach the Final Four since seeding began in 1979, but the second in three years following 11th-seeded VCU's improbable run in 2011. The Shockers' celebration was wild, if a bit disbelieving, in front of several thousand roaring fans.

"Last year we were watching all this on television," said Early, who scored 12 points despite spraining his ankle in the second half. "I just feel like we've got the same potential as those (big-name) guys, regardless if they know who we are or not. We just tend to work hard."

Wichita State roared to a 20-point lead with 11 minutes to play after Ohio State played an awful first half, but LaQuinton Ross scored 15 of his 19 points after halftime, leading a ferocious rally that got the Buckeyes within three points in the final minutes.

Tekele Cotton hit a clutch 3-pointer for Wichita State with 2:20 left and grabbed a key offensive rebound moments later, allowing VanVleet to score on a shot that bounced all over the rim before dropping. Ron Baker and Cotton hit last-minute free throws to secure the second Final Four trip in Wichita State's history and a school-record 30th win.

"We're happy, but I'm still shocked," said Carl Hall, the glasses-wearing big man who scored eight points and led the Shockers' strong defensive effort. "We've got a team full of fighters. I brought them all together near the end and said, 'No matter what happens, I love y'all.' We had to fight so hard. We've got each other's backs, and it's hard to beat a team that's got five guys who work together like us."

Deshaun Thomas scored 21 points after missing nine of his first 12 shots for Ohio State, which made just 24 percent of its first-half shots. Aaron Craft scored nine points on 2-for-12 shooting against Armstead and a host of defenders for the Buckeyes, who dug a hole too deep to escape with their second-half rally.

"The way we shot coming into the Sweet 16, Elite Eight, everything was falling," Thomas said. "Today, it just wasn't our night. Nothing was falling. We had great looks, some of them, but they just weren't falling."

Yet after two weeks of upsets in the wild West bracket, underdog Wichita State seemed an appropriate pick to cut down Staples Center's nets. The Shockers' well-balanced roster managed built that enormous lead with the same consummate team play that they've shown throughout the tournament.

The Shockers are also the kings of Kansas, reaching the national semifinals after the powerful Jayhawks and Kansas State both went down.

Two sections packed with cheering Shockers fans provided all the encouragement necessary for a team that didn't win the Missouri Valley Conference tournament and was thought to be a bubble team for an NCAA berth. Now, Wichita State is the MVC's first Final Four team since Larry Bird led Indiana State to the title game in 1979.

Another giant awaits the Shockers in Atlanta next weekend: They'll face the winner of Sunday's Midwest Regional final between Duke and Louisville.

"We're all new to this, but I think we're ready for this," Early said. "We're going to prepare ourselves, and this game was pretty good preparation. We started at the bottom, and we've been working our way up."

Everybody chipped in for the Shockers. Armstead, the Oregon transfer, was named the regional's top player. Baker made nine free throws without a miss on his 20th birthday. And both Early and Hall returned to the court with second-half injuries, pushing Wichita State forward.

Seven seasons after underdog George Mason crashed the Final Four and underlined college basketball's growing parity, the Shockers are the latest smallish school to get on a big roll in the tournament. Butler made the national championship game in 2010 and 2011, and the Bulldogs were joined by that VCU team in the Final Four two years ago.

This year's tournament included stunning wins by Florida Gulf Coast, La Salle and Harvard, but nobody kept it going longer than Wichita State.

Although the Shockers have a beautiful home arena and robust support from fans and donors in Kansas' largest city, Marshall acknowledged that Wichita State's athletic budget is a fraction of what a BCS school can spend. He hasn't let it slow the Shockers, who made the NCAA tournament last year only to lose to 12th-seeded VCU in the first round.

After the Shockers easily beat La Salle two days ago to reach their first regional final since 1981, Marshall's pregame speech to the Shockers on Saturday finished with talk of cutting down the nets at Staples Center before getting on that plane back to Kansas, saying Wichita State didn't have to play "a perfect game" to beat mighty Ohio State.

"The Mecca awaits in Atlanta," he said.

Marshall was right, but he couldn't have anticipated just how imperfect Ohio State would be.

The postseason-tested Buckeyes appeared calm and confident during warmups in front of their healthy fan contingent, yet they proceeded to play the first half just like NCAA newbies.

They missed their first seven shots after the opening tip in a string capped by an airballed 3-pointer from Thomas, who missed his first five overall. The junior star was labeled "a bad-shot taker and a bad-shot maker" by Marshall on Friday, but he only lived up to the first part of that billing while going 4 for 13 in the first half.

Early hit two 3-pointers in the opening minutes, and the Shockers stretched their lead to 13 points shortly before halftime.

"You've got to give them credit," Craft said. "They really came out firing and we really didn't regain our footing until it was too late."

Hall went to the locker room after drawing a charge from Thomas early in the second half, holding the back of his head after Thomas' elbow clipped him on the jaw. Hall found his glasses and got back in the game 66 seconds later.

Wichita State gradually stretched its lead early in the second half, with Early's layup putting the Shockers up 53-33 with 12:09 to play.

Ross desperately tried to rally the Buckeyes, scoring eight consecutive points and leading a 23-6 run midway through the second half. Ohio State went into a full-court inbounds defense, and Shannon Scott's free throws with 2:49 left cut the lead to 62-59 ? but Ohio State couldn't get any closer.

Renowned music administrators, Stuart Worthington and Keith ...

slide seminar2 Renowned music administrators,  Stuart Worthington and Keith Harris hold music forum in GhanaA seminar on international artist, rights and music management has been held at the Ghana-India Kofi Annan Center of Excellence in ICT in Accra. The seminar was a collaborative effort between the Musicians Union of Ghana, MUSIGA and the British Council of Ghana.

The seminar had two major speakers in the persons of Stuart Worthington and Keith Harris. Seated with them on the High table were lawyer Mike Ocquaye and DJ Amess, a radio presenter and Artist Manager.

The seminar focused mainly on giving an overview, updating and helping participants to understand today?s music industry, general artist management where skills, roles and responsibilities of artists and managers were discussed. The various existing and new ways of making revenue in the music business as well as teamwork and 3rd?party relationships were also discussed.

Stuart Worthington, a provider of management consultancy, small business information, advice and guidance, professional training & development services for a range of clients and strategic partners and who has worked in most sectors of the cultural & creative / arts & entertainment / media industries spoke about a number of issues affecting musicians, managers and the entire complex situation of handling and sharing monies amongst the various players in the industry.

He entreated that all involved in the business of music should endeavor to gain knowledge and understanding of how money flows so the managers, artists and other stakeholders will know about the financial situations and their entitlement.

There were various issues concerning music sharing, copyright issues and talent management. Keith Harris, Director of Performer Affairs at PPL commented that on the issue of royalty payments, the only way Ghanaian artists can claim their royalties from other countries is when we have good enough systems in place to claim the royalties of artists of other countries.

He also spoke about artists creating good enough images of them and limiting their accessibility to their audience once they hit a certain level. There was a question on when an artist needs a manager to which Keith responded that in a situation where an artist is doing all the work, the very moment the business side of managing the talent begins to interfere with the creativity, someone has to be brought in to handle certain things and this person has to be a manager.

The issues that were disseminated at the seminar were infused with personal and professional experiences of the various speakers. At a point, Lawyer Mike Ocquaye entreated musicians to be serious about registering their music.

2013 New York Auto Show Winners and Losers - KickingTires

2014 Chevrolet Camaro

The New York International Auto Show proved to be one of the busiest of the auto-show season. Its two preview days were overflowing with new and redesigned cars that had Cars.com editors Mike Hanley, Joe Wiesenfelder, Joe Bruzek and Aaron Bragman scrambling through the Javits Center. With tired feet, we offer the hits and misses of the show.

Check out the Luxury Cars Winners and Losers here.

2014 Chevrolet Camaro

Mike Hanley:?Loser
The new slimmer front grille is a small change that achieves dramatic results, making an already sinister sports car even more so. I know the new taillights have a retro influence, but I'm not a fan and prefer the ones on the current car. What's more, it doesn't look like Chevrolet has done anything to address the Camaro's weight problem or ridiculously bad visibility.

Aaron Bragman:?Loser
I'm not a fan of this update. The Camaro has now looked as it does for seven years ? since the concept debuted in 2006 ? and the first refresh we get is this? The interior is still uncomfortable, poorly laid out and made from awful-quality plastics, and not even the arrival of a track monster, the Z/28, can distract from that. With a new Ford Mustang coming next year and a new Dodge Challenger coming in two, you'd have thought Chevy would have gone farther.

Joe Bruzek:?Loser
The new Z/28 is a spectacle of high-performance dedication. Unfortunately, it took removing air conditioning, sound insulation and all speakers except one to save 300 pounds, which is still roughly 270 pounds heavier than a Mustang GT. I don't think we'll see a lighter-weight Camaro across all models until a platform change happens. I do like the new retro taillights, however, and was never fond of the previous chrome-trimmed quad taillights.

Joe Wiesenfelder:?Loser
I think I can second, third and fourth many of the sentiments above. I haven't been a fan of this Camaro, and, as predicted, its weight problem can't be fixed until it's re-engineered. The interior also needed an ergonomics overhaul. Oddly enough, I like the nose and taillight changes. That isn't enough.

2014 Chevrolet Corvette Stingray Convertible Vettewl

MH: Winner
The Corvette Stingray convertible has the same sharply creased lines, gaping grille and stylized taillights of the coupe, but the transformation does away with the coupe's dramatically updated roofline in favor of a familiar-looking soft-top. I wish the soft-top's shape were a little more daring, but no one will care when the top's down, which will probably be most of the time with this car.

AB: Winner
Shut up about the square taillights already, they totally fit with the car's image and work with the overall look. Pretty much the only way to improve upon the Stingray coupe was to chop the top off, and here it is. Everything that's a plus for the coupe applies to the convertible: great interior, amazing technology, gorgeous body and now wind-in-the-hair fun too.

JB: Winner
Despite losing its roof, the Stingray convertible looks more complete with the top down now that the black roof, which looks out of place on anything but dark-colored cars, is gone. Sitting inside with the top down is as natural as any dedicated convertible designed just to be a convertible, which is a feat considering the drop-top has a coupe variant.

JW: Winner
Definitely the better-looking body style with the top down. (If it was ever on display with the top raised, I didn't see it.) I'm more pleased by the interior quality, which seems much better than what I saw in the coupe ? even under the harsh auto-show lights, unshadowed by a roof. Anyone notice the six-speed stick? Sure, it's expected, but I'd expect it in many, many performance and sports cars, and sometimes it just isn't there.

2014 Dodge Durango Durangowl

MH: Winner
The Durango's exterior updates are much more subtle in person; The full-width taillights are the only thing that really stand out. A large dashboard touch-screen and new controls improve an already good interior. New just a few years ago, the Durango wasn't especially in need of a refresh, which makes all the changes for 2014 a pleasant surprise.

AB: Winner
The Durango is perhaps the best SUV that nobody's buying, and the new one is just that much better. Like Jeep's approach to the new Grand Cherokee, Dodge fixed the elements that needed fixing and left the rest of it alone. Even better fuel economy than before, a top-notch multimedia system, more than adequate power, butch looks and real seven-passenger room for mid-$30,000s? Why aren't you buying these, America?

JB: Winner
The subtle exterior changes add nice flair to the already attractive Durango, especially the rear taillights that look stunning when illuminated. Plus Dodge adds its proven 8.4-inch Uconnect touch-screen multimedia system, which is one of the best in the business and a notable knock against the Durango when it didn't have it.

JW: Winner
As I expressed in the Up Close, how many SUVs are this recognizable from behind, day or night, from a half-mile away? How many of those actually look good, too? Good exterior, good interior, big touch-screen and a rotary knob gear selector rather than the Grand Cherokee's springy T-handle. Nothing seems to have been done in this update that didn't need doing.

2014 Honda Odyssey Odysseywl

MH:?Loser
Just when you think cars have all the features you could possibly need, Honda comes out with a built-in vacuum cleaner for its Odyssey minivan, which makes all the sense in the world for this family-focused vehicle. What doesn't make sense is that it's exclusively offered on the Touring Elite model, a luxury minivan that costs nearly $45,000. Why not offer it on the lower-level EX trim?

AB: Winner
Of course it's about the HondaVac system. Honda has come up with the first actual innovation in the minivan world since Chrysler's Stow 'n Go seating, and even if it is a little gimmicky, it's a real-world useful bit of kit that owners all over will actually employ. Pro tip: Parents, buy yourself a Flowbee and the lil' snowflakes can give each other haircuts on the way to school! Such a time-saver!

JB:?Loser
I applaud Honda's innovation and real-world functionality of the HondaVac. It's not a wimpy vacuum by any means. It is very lazy, however. A $30 garage vacuum will do the same thing, and when on the road a $1 car-wash vacuum cleans up impromptu hissy-fit messes.

JW: Winner
Automotive gold, that vacuum system is. Stow 'n Go is a great comparison, because I believe its role in keeping Chrysler and Dodge alive in the minivan segment can't be overstated. Have you sat in those seats? They're terrible, but the way they fold into the floor is so slick that they've charmed many a buyer ? who might not ultimately fold them often enough to justify the discomfort. The Odyssey vacuum would likewise lure buyers even if it didn't work well, but it seems to.

2014 Jeep Cherokee 2014 Jeep Cherokee

MH: Winner
It's all in the name. Jeep would have saved itself a lot of unnecessary comparisons with the previous-generation Cherokee SUV if it had come up with a different name for this all-new crossover. Whether you love or hate the design ? and after seeing it in person, I kind of love it ? the Cherokee demands your attention. There's a lot of substance here, too, with a high-quality interior and a roomy backseat. Priced right, it should be a hit.

AB:?Loser
It's the two faces that disturb me. There's the squinty-eyed predatory face up top descending upon the screaming, droopy-eyed face below it. See it? Admittedly, I first saw this trucklet at a preview in December, and it had chrome reflectors for those middle lights that threw everything off ? it actually does look better with them blacked out and blended into the lower bumper. I understand Jeep needs to get more aerodynamic for fuel-economy gains, but this just loses too many of the traditional Jeep styling cues in the process. Cherokee isn't the only name I keep hearing in relation to this new truck ? the other one is Pontiac Aztek.

JB: Winner
Love it. The Cherokee is freshly designed and functional, and it's significantly more attractive in person. There's dedication in the available trim levels to satisfy road goers with the Limited as well as off-road fiends. Trailhawk off-road models look especially mean, and with matte highlights, I see the Warthog multipurpose vehicle from the Halo video-game series.

JW: Winner
JB sees the what from the what? I've respected the styling since a sneak preview a few months ago, and I like it more now. Honestly, the small backseat and cargo area are major problems, but the front seats, interior quality, features and capability are all upsides. If Jeep dumps the Compass and Patriot, builds something larger and stops calling the Cherokee midsize, there will be fewer objective aspects to complain about.

2014 Kia Soul 2014 Kia Soul

MH:?Loser
The Soul gets some significant platform updates for 2014, but you wouldn't really know it from looking at it. When cars are defined by their designs, like they are with the Nissan Cube and Scion xB, evolving the concept is a big challenge and it's no less of one here.

AB: Winner
I've always liked the Soul, even with its former Playskool-grade interior, I've found it to be comfortable, funky and unique, and the new one looks like even more fun. However, I'm worried that Kia is trying to make themselves a Juke or even a Mini competitor here. This new model has a lot of luxury content that's just going to add weight and cost. No Soul should cost anywhere near $30,000.

JB: Winner
The Soul's proportions and function have always been a winning combination. Its interior has not with mostly cheap materials that don't look or feel of much quality. That's changed for 2014, and it's a noticeable improvement with more soft-touch materials and black-gloss finish trim pieces.

JW: Winner
The exterior changes take away from the Soul, making it less distinctive in front and more distinctive (in a negative way) in back, but this is one of those cases where I prefer to let individuals make their own aesthetic judgments. At least it's different. The interior is much improved. There are lots of advanced features along with the quality gains. If the ride and handling improve, as they have in other recently redone Kia vehicles, this will be a winner many times over.

2014 Mitsubishi Mirage Miragewinnersandlosers

MH: Winner
Perhaps reading about the Mirage's puny specs, like its 74-horsepower three-cylinder engine, created unnaturally low expectations for Mitsubishi's new subcompact hatchback, but I walked away impressed with its roomy and relatively comfortable cabin. When you take into account its expected thriftiness at the gas station, the Mirage might surprise people.

AB: Winner
It wins simply because it makes the Smart ForTwo completely irrelevant. The Mirage's three-cylinder engine has 4 hp more than the Smart's three-cylinder; it handily trounces the ForTwo's fuel economy (by a lot) and features room for two extra people and their stuff. Is this going to save Mitsubishi in the U.S. market? Not a chance. Scrapping all of its U.S.-made midsize cars and SUVs in favor of expensive, imported-from-Japan compacts and minicars is no recipe for success, but it might delay Mitsubishi's demise a while.

JB: Winner
It pains me to call a dinky car with 74 hp a winner, but its fuel economy of 40 mpg city/highway combined and potentially low price could be a winner for value shoppers looking for a high-mileage small car. Tiny cars like the Chevrolet Spark and Smart ForTwo can't match the Mirage's mileage claim.

JW: Loser
Aaron is still new to the team, so he hasn't learned that the ForTwo has been dead to us for years. The legit competitors are the Spark and Scion iQ. The Spark was surprisingly impressive even after I drove it. The iQ? Only until I drove it. A 74-hp three-banger and continuously variable automatic transmission are a recipe for disaster. This thing looks so old inside that I'm surprised Coda hasn't electrified it.

2014 Scion tC 2014 Scion tC

MH: Loser
The updated tC coupe incorporates some design cues from the brand's FR-S sports car, especially up front, but the look doesn't go all that well with the rest of the design. Not helping matters is an interior that's heavy on cheap-looking ? and feeling ? materials. You can do better, Scion; I know you can.

AB: Loser
Snore. Same old car but now with a Toyota Avalon front end, dull gray interior and LED "Altezza-style" taillights that went out of style five years ago. In a world where you can get a 201-hp Veloster Turbo or Honda Civic Si coupe for just a couple grand more, where's the appeal of the boring tC?

JB: Loser
Despite interior updates, the Scion tC still isn't on the same level as the Hyundai Veloster or Honda Civic. Its inspiration from the awesome FR-S should have been left where it belongs -- on the rear-wheel-drive sports car, though you can't blame Scion for wanting to see some of that car's success on the less interesting tC.

JW: Loser
Tale of two compacts: Honda and Scion came out with new generations; the Civic remained good but took a few steps backward. One model year later, Honda fixed it. The tC took more steps backward in 2011 and Scion still hasn't fixed it. I'd respect them more if they reverted to the gen-one tC.

2014 Subaru XV Crosstrek Hybrid XvWL

MH: Loser
I like the XV Crosstrek and think the gas-only version should do well for Subaru, but the hybrid's estimated gas mileage ? only 3 mpg better in combined city/highway driving ? is a problem in an era when hybrids must produce big fuel-economy gains to warrant their extra cost. Pricing hasn't been released yet, but the upcharge will have to be pretty small for the hybrid version to be worth it for most buyers.

AB: Loser
For Subie's first hybrid, this thing is lame. The whole point of a hybrid is better fuel economy, and the XV Crosstrek Hybrid just isn't enough of a hybrid to actually deliver. It's rated at 28/34 mpg city/highway, whereas the conventional version gets 25/33 mpg. It'll probably sell like crazy to loyal Subaru owners despite the extra cost and awful Linda Blair Upchuck Green paint, but as hybrids go, this is weaksauce.

JB: Loser
Like Mike and Aaron mention, the mileage improvement is weak for a hybrid. Maybe an off-road-oriented XV Crosstrek model with a lifted suspension wasn't the best way to introduce a hybrid.

JW: Loser
Everything that's wrong with the hybrid movement is summed up here: not enough efficiency gained. Aaron's right that Subaru junkies will probably buy it, though if it doesn't drive as well as or better than the average hybrid, it could be dead in the water. Aaron's also wrong: Its character Regan MacNeil who puked green in Technicolor. Poor Linda Blair. She never recovered from that role.

Subaru WRX Concept Subaru WRX Concept

MH: Winner
The next version of the WRX likely won't be this aggressive-looking ? the WRX STI, perhaps ? but even if some of the bolder cues like the huge fender flares and massive rear diffuser are toned down the car's great stance and proportions should remain.

AB: Winner
Subaru almost always does gorgeous concept cars, and the WRX Concept is no exception. The problem is when Subie goes to turn the concept car into reality, and designers lose out to more conservative executives (see the Advanced Tourer Wagon concept from 2011 for confirmation). If the actual next-generation WRX looks as good as this low, wide sedan concept does, I will be stunned.

JB: Winner
Almost as an apology for the XV Crosstrek Hybrid, Subaru redeemed itself with the hot WRX Concept. The best way to view the WRX Concept is from the rear three-quarter view where the bulging rear fenders and sleek profile impress. Hopefully some of the design makes it to production because Subaru's track record isn't that great for translating a concept car into a production model.

JW: Winner
Great to stare at from many angles, especially when far-out concepts are in short supply, as they have been for a few years. JB's right about the rear three-quarter view. That's some jet-fighter stuff going on there. I hope they use a glowing badge in the grille of a real car someday.

2014 Toyota Highlander 2014 Toyota Highlander

MH: Winner
The new Highlander's big-mouth grille is more than a little off-putting in photos, but in-person the crossover wears it well and it's not nearly as overpowering. Add up all of the other significant exterior changes with the all-new interior and there's a lot that's new on the 2014 Highlander. It all works quite well.

AB: Winner
Some of the styling may be derivative, such as the profile that looks like Volkswagen's 2013 CrossBlue concept and the rear end that looks like a new Nissan Pathfinder, but I applaud Toyota for using some more aggressive styling cues for the front end. It's actually distinctive ? and when is the last time you heard that about a Toyota? The interior is a massive step up from the current Highlander, and from many recent Toyotas in general. Good to see content being put back in after years of cheapening out.

JB: Winner
Toyota took a chance with the 2014 Highlander's aggressive, unique exterior styling. And they nailed it. Previously a drab SUV that was practical but not particularly interesting is now even more attractive and higher quality while also improving usability. The interior of the upscale Limited trim level on display is almost as classy as the 2013 Toyota Avalon, and there's considerably more usability from the rear seating and cargo area.

JW: Winner
In our comparison test of large crossovers with three rows of seats, what held the 2011 Highlander back was its interior quality and its snug third row. Toyota addressed both. Definitely a winner.

2015 Volkswagen Golf, GTI 2015 Volkswagen Golf and GTI

MH: Winner
Some might complain that all the Golfs and GTIs of recent memory look the same ? they do to a certain degree ? but as hatchbacks go, the design is athletic, so why toss it out? I'll take the Golf's and GTI's classic lines over a busily styled hatchback any day.

AB: Winner
The Golf formula is pretty unique in the U.S. market: a relatively inexpensive hatchback with European handling, luxury-car interior quality and decent resale value. But the GTI is truly a benchmark, and this new one looks even better. Golfs never change too much between one generation and the next; but when you're this good, you never really have to.

JB: Loser
Seeing as I had to look for the "All-New Golf" license plates on the show floor to distinguish them from the old car, the Golf is easily forgettable under the auto-show lights. It is an impressive car, however, with a high-quality interior just as the Golf and GTI have been in previous generations.

JW: Loser
I'm on Team Bruzek for this one. They might even look more boring than the outgoing generation. From the rear three-quarter and profile views, the blue Golf looked slab-sided, though the red GTI came across better. Yes, it's nice inside, roomy and likely a great-driving car, but for a redesign, I want more of a redesign, even if it appeals less to me, personally, than to others (see Soul, above).

Bill Allowing Gold and Silver as Money; Bureaucratic Nightmare ...

I have encouraging news in the state of Arizona where lawmakers back gold, silver as currency.

The measure is Arizona's latest jab at the federal government, which prohibits states from minting their own money. It also reflects a growing distrust of government-backed money.

The bill, which advanced in a 4-2 vote by a House committee Monday, states that gold and silver should be legal currency not subject to tax or regulation as property. The Republican-led Senate gave the bill its blessing in February in a 17-11 partisan vote.

The bill would let people use the precious metals as money as long as businesses agree to take them. If made law, it would take effect in 2014.

Democrats oppose the measure. They say it would be a bureaucratic nightmare because businesses don't have the equipment to determine the value of gold and silver.

Bureaucratic Nightmare?

Nonsense.

The bill is well written and extremely well thought out. It does not force companies to accept gold or silver (nor should it), it merely allows businesses to do so if they want. Any company that does not want to deal with gold or silver will not have to. So where's the nightmare?

States will not be minting their own money under such a proposal (nor should they) so there is no conflict on that part of Federal law.

I commend this bill, expect Arizona lawmakers to pass it, and urge the Governor to sign it. When that happens, gold will once again be legal money.

I support gold as money and believe gold is money whether or not the bill passes.

There is significant reason for people to distrust government-sponsored fiat currencies backed by nothing. I made the case recently in Fraudulent Guarantees; Fictional Reserve Lending; Comparison of US to Cyprus; What About New Zealand?

Here is a brief synopsis, but I encourage you to read the full article.

Monetary Recap

  • Base Money Supply: $2.9 Trillion
  • M1: 2.4 Trillion
  • M2: 10.4 Trillion
  • Total Credit Market Debt Owed: $56.3 trillion
One Giant Ponzi Scheme

Clearly far more money has been lent than exists. How can it possibly be paid back? If it can't be paid back, how good is a government guarantee on deposits?

In 2010 Bernanke proposed ending reserve requirements completely, but long-time Mish readers understand what Bernanke proposed is the de facto state of affairs already. (see the above link for an explanation).


Five Key Points
  1. In a Fractional Reserve Lending scheme, the notion there are meaningful reserves is ridiculous.
  2. Far more money has been lent out than really exists (the rest is a fictional accounting entry).
  3. Fractional reserve lending constitutes fraud (just as lending something you do not own is fraud).
  4. There is no way for all this money to be paid back (so it won't be).
  5. The Reserve Bank of New Zealand has the most sensible policy on deposit insurance of all the world's central banks. (NZ offers no deposit insurance). See my article for a full explanation.

Austrian police chase herd of cattle through town

VIENNA (AP) ? Austrian police and firefighters have taken on the role of urban cowboys in a two-day round-up of a herd of cattle that broke out of a fenced-off pasture and decided to go into town.

A police statement says the 43 steers defied attempts by police and volunteer firefighters to recapture them after wandering off Thursday and heading toward the Upper Austrian town of Freistadt. After being chased away from the railway station, they endangered motorists by stampeding onto a two-lane highway before running into a town suburb.

Two firefighters who tried to stop them were injured and needed hospital treatment.

The statement says 18 of the animals remain on the loose Friday. The rest have been corralled or tranquilized.

Syrian officials: 15 killed in university attack

DAMASCUS, Syria (AP) ? Mortar shells slammed into a cafeteria at Damascus University on Thursday, killing at least 15 people and wounding 20 in what was the deadliest in a string of such attacks on President Bashar Assad's seat of power, state media and officials said.

Rebels began firing shells at the capital earlier this year, and the strikes have become increasingly common in recent weeks as rebels clash with government troops on the east and south sides of the city.

State-run TV said 15 people were killed when mortar shells struck the cafeteria of the university's architecture department in the central Baramkeh district. A Syrian official who spoke to The Associated Press on condition of anonymity because he was not authorized to give official statements said 20 people were wounded in the attack.

There was no immediate claim of responsibility for the attack, which came two days after rebels barraged Damascus with mortar shells that killed at least three people and wounded dozens.

The shelling rarely causes many casualties, but it has shattered the aura of normalcy the regime has tried to cultivate in Damascus. In recent days, rebels have struck deeper than ever into the heart of the city in a new tactic to try and loosen Assad's grip on his main stronghold.

The government blamed "terrorists," the term it uses for rebels fighting to oust Assad, and called the attack as a "barbaric massacre."

Government-run Al-Ikhbariya TV showed footage of plastic tables and chairs turned upside down, shattered glass and pens and books scattered on the floor. Pools of blood were seen on the floor of the open-air cafeteria. The station showed paramedics trying to revive a wounded girl.

The Britain-based Syrian Observatory for Human Rights confirmed the attack, saying many of the wounded were in critical condition.

Syria's crisis began in March 2011 with protests demanding Assad's ouster. Following a harsh government crackdown, the uprising steadily grew more violent until it became a full-fledged civil war. The U.N. says Syria's two-year civil war has killed more than 70,000 people.

The mortar attack at the university occurred as officials denied opposition claims that an Iranian cargo plane allegedly carrying weapons to Assad's regime was hit as it landed at Damascus International Airport.

Al-Arabiya and Al-Jazeera TV quoted activists as saying that the plane was hit Wednesday night and caught fire as it was landing. State-run TV denied the report while the Observatory chief, Rami Abdul-Rahman, said he could not confirm that such an incident happened.

Ghaidaa Abdul-Latif, the general director of the Syrian Arab Airlines, denied in a telephone interview with The AP the occurrence of any incident at the airport. She stressed that all reports about the incident were "absolutely untrue."

Earlier in the day, activists said Syrian rebels attacked army checkpoints in and around a key southern town that is a gateway to Damascus.

The Observatory said rebel attacks were under way in and around Dael in the strategic Daraa province, which borders Jordan. The Local Coordination Committees, another activists group, said regime bombardment of Dael killed at least three people on Thursday.

The Observatory also reported violence in other parts of Syria, including the northern regions of Idlib and Aleppo, and air raids on the suburbs of Damascus.

The fighting comes as Mideast powers opposed to Assad have stepped up weapons supplies to Syrian rebels in coordination with the U.S. in preparation for a push on the Syrian capital, according to officials and military experts who spoke to the AP in Jordan.

In Jordan, the U.N. refugee agency said a riot broke out at a refugee camp for Syrians in the country after some of the refugees were told they could not return home.

Ali Bibi, a U.N. refugee liaison officer in Jordan, said it was unclear how many refugees were involved in Thursday's melee at the Zaatari camp. The riot broke out after some Syrians in the camp tried to board buses to return to their country.

He said Jordanian authorities refused to let the buses head to the border because of ongoing clashes between the rebels and Assad's forces in southern Syria, just across the border from Jordan. Bibi said there were no immediate reports of injuries.

Turkish officials on Thursday denied reports that the country was deporting several hundreds of Syrian refugees for causing disturbances inside a refugee camp near the border. A Foreign Ministry official said, however, that a group of 100 refugees asked to be allowed to leave the camp and to return to Syria on their own free will.

A fire at the camp in the town of Akcakale late Wednesday killed a 7-year-old child and sparked unrest among the refugees.

A camp security official said local authorities identified about 300 people who allegedly caused the disturbance and prepared to deport them. But the move was stopped by government officials, he said. He spoke on condition of anonymity because he was not allowed to discuss the situation in the camp with journalists.

The U.N. refugee agency could not immediately confirm the reports, but said it was concerned by allegations of possible deportations from Akcakale and was seeking further information.

In Israel, the military said it was beefing up medical teams along the border with Syria following several cases of wounded Syrians crossing the frontier to seek medical assistance.

A military official, who spoke on condition of anonymity under military protocol, said on Thursday there have been "numerous incidents" in recent months in which Syrians wounded in the fighting in their country arrived at the frontier for first aid from Israeli medics.

Eleven of them were taken and treated at Israeli hospitals, including one who died from his wounds on Wednesday. Others returned home after their conditions have improved.

The official spoke on condition of anonymity under military protocol. He said the military's focus in the Israeli-held Golan Heights was still on security and defense but that Israel sent extra medical teams to the area realizing more wounded could soon arrive.

OUYA available at retail on June 4 for $99

OUYA available at retail on June 4 for TKTK DNP

The Android-powered $99 OUYA game console becomes available at retail on June 4th -- a date which was revealed this week during the Game Developers Conference. OUYA's calling June 4th its "official launch date," despite Kickstarter backers receiving units starting this month. Essentially, the two month waiting period between Kickstarter boxes and retail availability is being used as a consumer beta, giving OUYA time to adjust its software after getting feedback from early adopters.

It's not clear if bundles will be available, but the game console itself and a controller (as well as power and HDMI cables, plus two AA batteries for the controller) are included in the $99 package. Major retailers like Amazon, Best Buy, and others are on board, so it shouldn't be too hard locating one in June should your interested be piqued -- and yes, pre-orders are available. Of course, it's a pretty small little game console, so it might be a bit tough locating the thing with your eyes.

Replace Your Engine Air Filter At Bear Automotive & RV Service Inc ...

Grand Junction Car Advice

When driving around Grand Junction, your minivan engine needs clean air to burn the fuel ? and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas.

All that air passes through a filter that catches the dust and dirt. Eventually the filter gets completely full. Because the filter can only hold so much, dirt starts getting through. This dirty air passes through the mass airflow sensor, and starts to accumulate on the delicate sensor element. The mass air flow sensor measures how much air is getting into your engine. When the airflow reading is incorrect, your minivan engine doesn?t get the proper amount of fuel. It runs rough and doesn?t perform as well as it should.

Eventually, the sensor is so damaged it needs to be replaced ? which is pricy. In fact you could buy a case or two of air filters for the cost of a sensor replacement.

Of course, that dirty air keeps on going through to your minivan engine where it?s burned along with the fuel, which dirties up your combustion chamber and increases harmful exhaust emissions ? not a good thing for Grand Junction air quality, not to mention our lungs.

When your knowledgeable Bear Automotive & RV Service Inc service advisor brings out your dirty air filter and recommends a replacement, remember the cost and poor performance that can be waiting for you down the road if you neglect this simple Bear Automotive & RV Service Inc service. Ask your Bear Automotive & RV Service Inc advisor if it?s time to replace your engine air filter.

Engineers enable 'bulk' silicon to emit visible light for the first time

Mar. 27, 2013 ? Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass those limitations, but the components of such computers require semiconductors that can emit light.

Now, research from the University of Pennsylvania has enabled "bulk" silicon to emit broad-spectrum, visible light for the first time, opening the possibility of using the element in devices that have both electronic and photonic components.

The research was conducted by associate professor Ritesh Agarwal, postdoctoral fellow Chang-Hee Cho and graduate students Carlos O. Aspetti and Joohee Park, all of the Department of Materials Science and Engineering in Penn's School of Engineering and Applied Science.

Their work was published in Nature Photonics.

Certain semiconductors, when imparted with energy, in turn emit light; they directly produce photons, instead of producing heat. This phenomenon is commonplace and used in light-emitting diodes, or LEDs, which are ubiquitous in traffic signals, new types of light bulbs, computer displays and other electronic and optoelectronic devices. Getting the desired photonic properties often means finding the right semiconducting material. Agarwal's group produced the first ever all-optical switch out of cadmium sulfide nanowires, for example.

Semiconducting materials -- especially silicon -- form the backbone of modern electronics and computing, but, unfortunately, silicon is an especially poor emitter of light. It belongs to a group of semiconducting materials, which turns added energy into heat. This makes integrating electronic and photonic circuits a challenge; materials with desirable photonic properties, such as cadmium sulfide, tend to have poor electrical properties and vice versa and are not compatible with silicon-based electronic devices.

"The problem is that electronic devices are made of silicon and photonic devices are typically not," Agarwal said. "Silicon doesn't emit light and the materials that do aren't necessarily the best materials for making electronic devices."

With silicon entrenched as the material of choice for the electronics industry, augmenting its optical properties so it could be integrated into photonic circuitry would make consumer-level applications of the technology more feasible.

"People have tried to solve this problem by doping silicon with other materials, but the light emission is then in the very long wavelength range, so it's not visible and not very efficient and can degrade its electronic properties," Agarwal said. "Another approach is to make silicon devices that are very small, five nanometers in diameter or less. At that size you have quantum confinement effects, which allows the device to emit light, but making electrical connections at that scale isn't currently feasible, and the electrical conductivity would be very low."

To get elemental, "bulk" silicon to emit light, Agarwal's team drew upon previous research they had conducted on plasmonic cavities. In that earlier work, the researchers wrapped a cadmium sulfide nanowire first in a layer of silicon dioxide, essentially glass, and then in a layer of silver. The silver coating supports what are known as surface plasmons, waves that are a combination of oscillating metal electrons and of light. These surface plasmons are highly confined to the surface where the silicon dioxide and silver layers meet. For certain nanowire sizes, the silver coating creates pockets of resonance and hence highly confined electromagnetic fields -- in other words, light -- within the nanostructure.

Normally, after excitation the semiconductor must first "cool down," releasing energy as heat, before "jumping" back to the ground state and finally releasing the remaining energy as light. The Penn team's semiconductor nanowires coupled with plasmonic nanocavities, however, can jump directly from a high-energy excited state to the ground state, all but eliminating the heat-releasing cool-down period. This ultra-fast emission time opens the possibility of producing light from semiconductors such as silicon that might otherwise only produce heat.

"If we can make the carriers recombine immediately," Agarwal said, "then we can produce light in silicon."

In their latest work, the group wrapped pure silicon nanowires in a similar fashion, first with a coating of glass and then one of silver. In this case, however, the silver did not wrap completely around the wire as the researchers first mounted the glass-coated silicon on a sperate pane of glass. Tucking under the curve of the wire but unable to go between it and the glass substrate, the silver coating took on the shape of the greek letter omega -- ? -- while still acting as a plasmonic cavity.

Critically, the transparent bottom of the omega allowed the researchers to impart energy to the semiconductor with a laser and then examine the light silicon emitted.

Even though the silicon nanowire is excited at a single energy level, which corresponds to the wavelength of the blue laser, it produces white light that spans the visible spectrum. This translates into a broad bandwidth for possible operation in a photonic or optoelectronic device. In the future, it should also be possible to excite these silicon nanowires electrically.

"If you can make the silicon emit light itself, you don't have to have an external light source on the chip," Agarwal said. "We could excite the silicon electrically and get the same effect, and we can make it work with wires from 20 to 100 nanometers in diameter, so it's very compatible in terms of length scale with current electronics."

The research was supported by the U.S. Army Research Office and the National Institutes of Health.

(AP) ? The putter D.A. Points once took from his mother paid off nicely for him Thursday in the Houston Open.

Points opened with five straight birdies and wound up with an 8-under 64 on a pleasant morning with only moderate wind at Redstone Golf Club. He had a one-shot lead over Cameron Tringale and afternoon starter John Rollins with the late groups still on the course.

Rory McIlroy, in his final start before the Masters, was 3-over par after a double bogey on the par-5 eighth, then rallied for a 73 in his afternoon round.

Points first borrowed the Ping Anser from his mother during his junior years in Illinois, and like most golfers, he abandoned it once he stopped making putts. But he recently asked Ping to clean it up for him and add some weight. He also got a putting lesson ? no, not from Steve Stricker ? and he was on his way.

"Maybe I'm an idiot for not having used this putter the whole time," Points said. "It worked well today."

Points, whose only win came with actor Bill Murray at his side at the Pebble Beach National Pro-am, made all five of his opening birdies from inside 15 feet. He dropped only one shot along the way.

Angel Cabrera of Argentina, a two-time major champion who lives in Houston, was in the group at 66.

Phil Mickelson was at 4 under and right in the mix until he hit his tee shot into the water on the sixth hole and made double bogey, nearly hooked a 3-wood into the hazard on the next hole and three-putted for bogey, and then made bogey on the par-3 ninth from a bunker to wind up at 72.

"It was a disappointing finish," Mickelson said. "I feel really good with the putter, and I believe that as the tournament goes on, I'll get better."

Mickelson played with defending champion Hunter Mahan, who didn't hit the ball his best and it finally caught up with him at the end for a 74. Also in the group was Geoff Ogilvy, who needs to finish in the top 50 in the world to get into the Masters. Ogilvy is currently at No. 50, though he will lose spots through the formula this week. He had three penalty shots in his round of 73.

Lee Westwood hit two shots in the water and still salvaged a bogey and was in the large group at 68 that included Riviera winner John Merrick and Jimmy Walker.

Charles Howell III had a 69 in his bid to get into his hometown major at Augusta National. Howell would need to finish at least in fourth place alone to have any chance of moving into the top 50.

For Points, Tringale and so many others, they need a win to get into the Masters.

Points was just trying to see some reasonable results, having made only two cuts all year. He did manage to join a group of stars in the Tavistock Cup earlier this week, and upon leaving home for Tuesday, he grabbed a handful of putters. One of them once belonged to his mother.

Ping rep Matt Rollins had some weights added to the putter, and equally important was an impromptu lesson from Lamar golf coach Brian White.

"It's one of those things," Points said. "I holed some nice par putts yesterday in my pro-am. I didn't hit it great, but I made a few good putts and the ball was going in the hole with nice pace and rolling real tight. And I thought, 'All right, this might be the key that kind of gets me going.'"

That it did.

Mickelson, meanwhile, was going along nicely despite some errant tee shots, such as his one on the 12th hole. He sliced the tee shot so far left that it bounced off the cart path, across the 13th tee box and down a slope toward the bushes. He was about pin-high, only 100 yards left of the green. He hit wedge into about 15 feet and turned to the gallery and said, "It's all about angles."

The angles caught up with him. Mickelson tee shot on the sixth never cleared the water, leading to his sloppy finish.

Mickelson enjoys playing the Houston Open before the Masters, but this is a different year. Because of the way the calendar falls, the Masters is a week later, and Houston is now two weeks before the first major of the year. This is only the second time in the last 15 years that Mickelson won't be playing the week immediately before Augusta.

Lefty also plans to skip the week before the U.S. Open.

"It's a very unusual situation for me here," he said. "I usually like to play the before. I'm going to have to learn how to do that, now that we're not really having tournaments conducive to getting ready for those events. This is a good opportunity for me to work on getting prepared properly in another spot outside of a tournament."

Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light

Mar. 3, 2013 ? Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both overcomes some important challenges of Heisenberg's famous Uncertainty Principle and also is applicable to qubits, the building blocks of quantum information theory.

They report their results in a paper published this week in Nature Photonics.

The direct measurement technique was first developed in 2011 by scientists at the National Research Council, Canada, to measure the wavefunction -- a way of determining the state of a quantum system.

Such direct measurements of the wavefunction had long seemed impossible because of a key tenet of the uncertainty principle -- the idea that certain properties of a quantum system could be known only poorly if certain other related properties were known with precision. The ability to make these measurements directly challenges the idea that full understanding of a quantum system could never come from direct observation.

The Rochester/Ottawa researchers, led by Robert Boyd, who has appointments at both universities, measured the polarization states of light -- the directions in which the electric and magnetic fields of the light oscillate. Their key result, like that of the team that pioneered direct measurement, is that it is possible to measure key related variables, known as "conjugate" variables, of a quantum particle or state directly. The polarization states of light can be used to encode information, which is why they can be the basis of qubits in quantum information applications.

"The ability to perform direct measurement of the quantum wavefunction has important future implications for quantum information science," explained Boyd, Canada Excellence Research Chair in Quantum Nonlinear Optics at the University of Ottawa and Professor of Optics and Physics at the University of Rochester. "Ongoing work in our group involves applying this technique to other systems, for example, measuring the form of a "mixed" (as opposed to a pure) quantum state."

Previously, a technique called quantum tomography has allowed researchers to measure the information contained in these quantum states, but only indirectly. Quantum tomography requires intensive post-processing of the data, and this is a time-consuming process that is not required in the direct measurement technique. Thus, in principle, the new technique provides the same information as quantum tomography but in significantly less time.

"The key to characterizing any quantum system is gathering information about conjugate variables," said co-author Jonathan Leach, who is now a lecturer at Heriot-Watt University, UK. "The reason it wasn't thought possible to measure two conjugate variables directly was because measuring one would destroy the wavefunction before the other one could be measured."

The direct measurement technique employs a "trick" to measure the first property in such a way that the system is not disturbed significantly and information about the second property can still be obtained. This careful measurement relies on the "weak measurement" of the first property followed by a "strong measurement" of the second property.

First described 25 years ago, weak measurement requires that the coupling between the system and what is used to measure it be, as its name suggests, "weak," which means that the system is barely disturbed in the measurement process. The downside of this type of measurement is that a single measurement only provides a small amount of information, and to get an accurate readout, the process has to be repeated multiple times and the average taken.

Boyd and his colleagues used the position and momentum of the light as the indicator of the polarization state. To couple the polarization to the spatial degree of freedom they used birefringent crystals: when light goes through such a crystal, there is a spatial separation introduced for different polarizations. For example, if light is made of a combination of horizontally and vertically polarized component, the positions of the individual components will spread out when it goes through the crystal according to its polarization. The thickness of the crystal can control the strength of the measurement, weak or strong, and determine the degree of separation, correspondingly small or large.

In this experiment, Boyd and his colleagues passed polarized light through two crystals of differing thicknesses: the first, a very thin crystal that "weakly" measures the horizontal and vertical polarization state; the second, a much thicker crystal that "strongly" measures the diagonal and anti-diagonal polarization state. As the first measurement was performed weakly, the system is not significantly disturbed, and therefore, information gained from the second measurement was still valid. This process is repeated several times to build up accurate statistics. Putting all of this together gives a full, direct characterization of the polarization states of the light.
