Lenovo Miix is a watered-down ThinkPad Tablet 2, starts at $500 (hands-on)

Lenovo Miix is a watered-down ThinkPad Tablet 2, starts at $500 (hands-on)

Comb through Lenovo's current product lineup, and you'll find a little something for everyone. A Windows 8 tablet for businesses? Check. How 'bout a consumer model? Yep, that too. But hey, you can never have too many, right? After releasing the IdeaTab Lynx tablet, Lenovo is now launching the Miix, a 10-inch model that's also meant to be used with a keyboard. All told, it's sort of like a watered-down ThinkPad Tablet 2, insofar as it has the same rubbery, soft-touch finish and some very similar specs. Chiefly, it has a dual-core Intel Atom processor along with a 10.1-inch, 1,366 x 768 display, 64GB of on-board storage, an optional keyboard case and a battery rated for 10 hours of runtime. The two even weigh about the same: 1.27 pounds for the Miix, and 1.25 pounds for the WiFi-only TP Tablet.

What's missing, of course, are all the goodies that make the ThinkPad more of a premium device -- you know, NFC, mobile broadband and an active digitizer for pen input. Also, whereas the TP Tablet 2 sports dual cameras, the Miix has just a front-facing webcam, and the resolution's been downgraded from two megapixels to 1.3. Expect it to hit shelves in Q3, with a starting price of $500 (that keyboard will cost $49 extra). For now, check out our hands-on photos below.

Samsung Galaxy NX Hands-On: I Can't Take My Eyes Off You (Should I?)

The first thing that strikes you about Samsung's new Android-powered interchangeable-lens camera is how big that 4.8-inch AMOLED screen looks on the back of a camera. Even when it's turned off, the blackness stares back at you like an enrapturing abyss.

Student engagement more complex, changeable than thought

June 20, 2013 ? A student who shows up on time for school and listens respectfully in class might appear fully engaged to outside observers, including teachers. But other measures of student engagement, including the student's emotional and cognitive involvement with the course material, may tell a different story -- one that could help teachers recognize students who are becoming less invested in their studies, according to a new study coauthored by a University of Pittsburgh researcher.

More importantly for educators, the study, published online in the professional journal Learning and Instruction, suggests that student engagement -- essential for success in school -- is malleable, and can be improved by promoting a positive school environment. The result paves the way for future work to offer teachers diagnostic tools for recognizing disengagement, as well as strategies for creating a school environment more conducive to student engagement.

"Enhancing student engagement has been identified as the key to addressing problems of low achievement, high levels of student misbehavior, alienation, and high dropout rates," said Ming-Te Wang, assistant professor of psychology in education in the School of Education and of psychology in the Kenneth P. Dietrich School of Arts and Sciences at Pitt, who coauthored the study with Jacquelynne S. Eccles, the Wilbert McKeachie and Paul Pintrich Distinguished University Professor of Psychology and Education at the University of Michigan.

"When we talk about student engagement, we tend to talk only about student behavior," Wang added. "But my coauthor and I feel like that doesn't tell us the whole story. Emotion and cognition are also very important."

Wang and Eccles' study is among the first attempts by researchers to use data to explore a multidimensional approach to the question of student engagement. In the past, only behavioral measures of student engagement -- such as class attendance, turning in homework on time, and classroom participation -- had been evaluated when gauging student engagement. By conducting a study linking students' perceptions of the school environment with behavior, the authors have provided one of the first pieces of empirical research supporting the viability of the multidimensional perspective, which had previously been largely theoretical.

The researchers designed a 100-question survey that includes the evaluation of emotional engagement and cognitive engagement. Sample survey questions that tested emotional engagement in classes across all subject areas asked students to agree or disagree with statements such as "I find schoolwork interesting" and "I feel excited by the work in school." Sample questions concerning cognitive engagement asked students to provide ratings to questions like "How often do you make academic plans for solving problems?" and "How often do you try to relate what you are studying to other things you know about?"

Using the survey, Wang and Eccles conducted a two-year longitudinal study, tracking approximately 1,200 Maryland students from seventh through eighth grade. The authors also measured students' perceptions of their environment by having them answer questions in five areas: school structure support, which gauged the clarity of teacher expectations; provision of choice, which assessed students' opportunities to make learning-related decisions; teaching for relevance, which evaluated the frequency of activities deemed relevant to students' personal interests and goals; students' perceptions of the emotional support offered by teachers; and students' perceptions of how positive their relationships were with fellow students.

The authors found that students who felt that the subject matter being taught and the activities provided by their teachers were meaningful and related to their goals were more emotionally and cognitively engaged than were their peers. Adding measures of emotional and cognitive engagement could broaden researchers' perspectives on student engagement in future work in this area.

Also among the paper's main findings is that the school environment can and, indeed, should be changed if it is impeding student engagement. A positive and supportive school environment is marked, Wang said, by "positive relationships with teachers and peers. Schools must provide opportunities for students to make their own choices. But they also must create a more structured environment so students know what to do, what to expect, from school." Wang also noted, however, that there is no "one size fits all" strategy to the problem of student engagement.

"Usually people say, 'Yes, autonomy is beneficial. We want to provide students with choices in school,'" Wang said. "This is the case for high achievers, but not low achievers. Low achievers want more structure, more guidelines."

As a result, Wang said, teachers must take into account individual variation among students in order to fulfill the needs of each student.

Wang's current work, undertaken in partnership with six Allegheny County school districts, focuses on developing a diagnostic tool that teachers can use to identify students who are disengaged from school, with a specific emphasis on math and science classes.

LED-powered 'privacy visor' thwarts facial recognition

Isao Echizen wearing the privacy visor.

Worried that your face is being detected and recorded on everything from security cameras to Google Glass? Don these infrared-emitting glasses to prevent your face from being recognized, and your only worry will be how dorky you look.

The "privacy visor," created by associate professor Isao Echizen at Japan's National Institute of Informatics, use bright, near-infrared LEDs to blast cameras with light that they can see but humans can't. The software that detects faces gets confused and decides that this brightly lit object isn't a face.

It's an idea that has existed in various forms since facial recognition became possible: whether wearing sunglasses, contorting one's features or just growing a beard, faking out the cameras has always been a possibility. These glasses are just a little more convenient.

With the IR emitters adding noise to the camera's image, the face cannot be detected.

While it works, this system can still be fooled. Many cameras filter out the type of light generated by the LEDs, for instance, and in some conditions the LEDs might not produce enough light to dazzle the camera. And, of course, there's nothing actually preventing pictures or video from being taken, even if your face couldn't be automatically detected in them.

The privacy visor won't be going on sale any time soon, but if wearable cameras get any more popular, there will surely be a demand for something like it before long. Watch the technology in action in this video from Diginfo.tv:

Gold hits two-and-half year low as Fed flags end to easy money

By Jan Harvey

LONDON (Reuters) - Gold plunged to its lowest in more than 2-1/2 years on Thursday, with investors exiting in droves after the U.S. Federal Reserve gave its most explicit signal yet that it plans to bring the era of easy money to an end.

Fed Chairman Ben Bernanke said on Wednesday the U.S. economy was expanding strongly enough for the central bank to begin slowing the pace of its bond-buying stimulus later this year.

Losses picked up momentum after bullion broke through its April low at $1,321 an ounce, a key support level, knocking it to a low of $1,285.90, down 4.5 percent and its weakest since September 2010.

Spot gold was down 4 percent at $1,296.60 an ounce at 10:54 a.m. ET, while U.S. gold futures for August delivery were down $77.20 an ounce at $1,297.00.

"Precious metals, in particular gold and silver, are losing their status as a viable asset class to hold," Viktor Nossek, head of research at Boost ETP, said. "The macroeconomic backdrop shows that the U.S. is recovering, Europe is restructuring and China is rebalancing."

He added, "Risk assets further out probably have more appeal because they have an underlying income stream that backs them up. Investors are pre-empting the view of global stabilization by selling precious metals."

The ultra-loose monetary policy brought in by the Fed to boost U.S. growth, which kept interest rates at rock bottom levels while stoking concerns about inflation, was a major factor fuelling a more than decade-long bull run in gold.

Indications that the policy was nearing an end have helped push prices down more than 20 percent this year after 12 straight years of gains. Gold is now firmly in bear market territory, more than 30 percent below its record high of $1,920.30 an ounce, set in September 2011.

"There's always been an expectation that there's inflation lurking around the corner with QE being instigated by the West, but it has never materialized," Nossek said. "The idea of pent-up inflation is not only dissipating, but is nowhere to be seen."

SILVER TUMBLES

Swiss bank UBS early on Thursday slashed its one-month target price for gold to $1,250 from $1,425 previously and its three-month forecast to $1,350 from $1,500, citing the Fed's move.

"This creates an increasingly difficult environment for gold," it said. "Slowing Fed asset purchases, with the end now potentially in sight, higher yields, a stronger dollar and continued improvements in the economy are significant obstacles that perpetuate an already very weak investor sentiment."

Physical gold demand in India, the world's biggest consumer of the metal, remained lackluster on Thursday despite a 4 percent drop in Indian gold prices, in sharp contrast to the response seen in April when spot prices plunged. Gold in rupee terms remains well above its April lows.

Silver was the biggest faller among the precious metals, sliding more than 6 percent to a session low at $19.68 an ounce, its weakest since September 2010. The metal was later down 6.1 percent at $20.02 an ounce.

Spot platinum was down 2.5 percent at $1,375.24 an ounce, while spot palladium was down 4.1 percent at $665. 72 an ounce.
