White House official fired over anonymous tweets
By Roberta Rampton and Steve Holland
WASHINGTON (Reuters) - A senior White House official who was helping negotiate nuclear issues with Iran has been fired after being unmasked as the acidic voice behind a Twitter account known for its insults of public figures at the White House and on Capitol Hill, a government official said on Tuesday.
Jofi Joseph was director of nuclear non-proliferation on the White House National Security Council staff, but for more than two years sent hundreds of anonymous and abrasive tweets using the handle @NatSecWonk.
He was fired last week after he was caught, the official said.
A White House official confirmed Joseph no longer worked there, but would not comment on personnel matters. The firing was first reported by the website Daily Beast.
In his Twitter biography, now removed from the social networking site, Joseph described himself as a "keen observer of the foreign policy and national security scene" who "unapologetically says what everyone else only thinks."
As the widely followed @NatSecWonk, Joseph speculated anonymously about the political motives and career moves of administration officials he worked with. They included Ben Rhodes, President Barack Obama's spokesman on national security issues.
This month, Joseph tweeted that Hillary Clinton, the former secretary of state, "had few policy goals and no wins" in the Middle East. He agreed with Republican Representative Darrell Issa, who has relentlessly pursued Clinton for administration actions after last year's attack on the U.S. diplomatic post in Benghazi, Libya.
"Look, Issa is an ass, but he's on to something here with the @HillaryClinton whitewash of accountability for Benghazi," he tweeted.
He also sniped at U.S. Ambassador to the United Nations Samantha Power's use of Twitter. "Can someone again brief @AmbassadorPower that Bashar Assad likely doesn't follow her Twitter feed?" he recently wrote.
Joseph did not respond to phone and email requests for comment, but he told the website Politico he regretted his tweets.
"What started out as an intended parody account of DC culture developed over time into a series of inappropriate and mean-spirited comments. I bear complete responsibility for this affair and I sincerely apologize to everyone I insulted," Joseph said in an email to Politico.
He also targeted journalists, including Daily Beast reporter Josh Rogin who broke the story of his firing. "Just a hunch, but I have the sense lots of people would like to punch @joshrogin in the face," he said earlier this month.

Guy On Train Live Tweets Former CIA Chief's On-Background Interview
You'd think he'd be more careful: The man who was once responsible for the National Security Agency and the Central Intelligence Agency was giving a background interview during a train ride, but he didn't notice that a fellow passenger was live tweeting the highlights.
In truth, we didn't learn any secrets from Ret. Gen. Michael Hayden, but Tom Matzzie, who used to work for the liberal group MoveOn.org, provided a riveting — and funny — account of the ordeal on his Twitter feed.
Matzzie said Hayden told the journalists that he could only be identified as a former senior administration official and then went on to give "disparaging quotes about" the Obama administration. At one point Hayden, said Matzzie, was "bragging about rendition and black sites."
Hayden, you might remember, served as the NSA director under Presidents Bill Clinton and George W. Bush. He served as CIA director for Bush and President Obama. Currently, he works for the Chertoff Group.
As you might imagine, eventually Hayden got a call from his office telling him what was going on. Matzzie wondered if he should hide. But Hayden graciously offered an interview and even took a picture with Matzzie.
Eventually, Matzzie tweeted, Hayden got off the train in Newark.
"He touched my back ... again," Matzzie tweeted, before adding that he was about to get off the train himself and someone should "email my wife and explain all this."

Saudi Women Go For A Spin In Latest Challenge To Driving Ban

A woman drives a car in Saudi Arabia on Sunday. Saudi Arabia is the only country where women are barred from driving, but activists have launched a renewed protest and are urging women to drive on Saturday.
Faisal Al Nasser/Reuters/Landov
Activists in Saudi Arabia tried once, they tried again and now they're making a third challenge to the kingdom's long-standing ban on female drivers.
Some women have recently made short drives, posting videos on social media sites, and many more are planning to get behind the wheel on Saturday.
Saudi Arabia is the only country in the world that effectively prohibits women from driving, a ban supported by conservative clerics. While there is no law formally banning female drivers, the government does not give them licenses.
Government authorities seem to be more lenient these days, however.
Sara Hussein, 32, says it's time to claim the right to drive.
"Think back in history — Rosa Parks was the only person who sat down on the bus, wasn't she? And then it started to happen gradually," Hussein says. "It does have to start with the few brave people who are willing to risk whatever there is to risk."
Hussein's mother, Aziza al-Yousef, who is in her 50s and teaches computer science at King Saud University, is a key organizer of the drive-in. Activists set Saturday as a date for a national road rally, but also encouraged women to just get behind the wheel any time.
"We are saying, 'Just go ahead and drive now,' " says al-Yousef. "I know women started driving. The messages are in the hundreds. We are counting the videotapes."
YouTube
Activists have been challenging Saudi Arabia's ban on female drivers by taking to the road and posting videos. Here is one of what organizers say are 100 videos posted so far.
The mother and daughter say the videos are coming from across the kingdom and even show one man teaching his wife and sister to drive.
Relying On Male Drivers
Saudi Arabia was made for driving, with wide open spaces and cheap gas. The sprawling capital, Riyadh, is as big as Los Angeles, with no dependable public transportation.
Women must rely on men to drive them around. They may be male relatives or drivers who are part of the country's imported labor. But this is expensive and an intrusion into their lives, many women say.
As the country changes bit by bit, the prohibition on female drivers can contradict other efforts by the government. For example, the government is urging private companies to hire more women. It is hard to see how that can happen unless women can drive to work, Hussein says.
"No one has been given orders from higher up" to arrest female drivers, she adds.
Al-Yousef says this campaign, the third challenge to the driving ban, has learned from past mistakes.
In 1990, 47 women made the first attempt to challenge the ban. They all lost their jobs, were prohibited from traveling for years, and were shunned for their defiance.
The next challenge came in 2011, when activists Maha al-Qatani was the first Saudi woman to get a traffic ticket. The campaign fizzled after some women were jailed for driving. But soon after, King Abdullah said women could vote in local elections, and 30 women were appointed to the 150-member Shura Council, an advisory body to the king.
Going For A Spin
Al-Yousef — who has an international driver's license — says she and other drivers don't want to break laws aside from the one banning driving.
She now takes a short drive every day and invites me to join her for a cruise around the capital. We get in the front, her male driver climbs in the back, and we take to the road.
"I need people to see that it is normal; we have to let people accept it," al-Yousef says. "It doesn't mean anything if you drive only one day."
The afternoon traffic is so heavy that nobody notices two women in the front seat of a car.
Then we approach a police station.
"Let's see what their reaction is," she says. "You watch it; it's going to be on your right."
She says the head of the national police stated publicly that his officers would not arrest women for driving. But they will ticket those without a license, which is impossible for a woman to get here.
Al-Yousef drives like a pro. She learned while attending a university in the U.S. The only time she shows excitement is when another activist calls her.
"I am driving!" she announces with a distinct rise in her voice.
We end our drive at her front door, where her husband is waiting to meet her.
"Hello, I'm a coward. How do you do," her husband, Moisen al-Haydar, says with a laugh.
Al-Haydar says he's given up driving. He's proud of his wife for braving Riyadh's hectic traffic. He supports her driving campaign, but he's worried, too.
Threats Against Activists
There have been online threats and insults against activists. Al-Yousef filed a case this week against the attackers in court. Also this week, conservative clerics urged King Abdullah to stop Saturday's drive-in, but the king did not meet with the complaining clerics.
Al-Yousef sweeps away her husband's concerns and sits down to check the latest driving videos.
"We've had four today and we are now up to 100 videos," she says as she turns up the volume on the latest driving demonstration.
Al-Yousef translates the Arabic in the video: "She says this is a very positive movement; Saudi ladies should have the choice to drive her own car. And she named the tape, 'Yes, we can.' "
The final decision is up to the king, who has said he believes women have the right to drive, but hasn't said when.

A Diagram Of HealthCare.gov, Based On The People Who Built It
An attempt to draw out the various parts of HealthCare.gov's tech system, based on the testimony of its contractors.

An attempt to draw out the various parts of HealthCare.gov's tech system, based on the testimony of its contractors.
Elise Hu/NPR
One of the major issues that's emerged since the failed rollout of HealthCare.gov is that there was no lead contractor on the project. (CGI Federal was the biggest contractor — awarded the most expensive contract — but says it did not have oversight over the other parts of the system.) Instead, the quarterbacking was left to the Centers for Medicare and Medicaid Services, a subagency of the Department of Health and Human Services.
As it's become clear recently, the team at CMS did not have the in-house technological expertise to be an effective "quarterback" over a complicated and unprecedented tech system.*
The testimony of contractors on the Hill today before the House Energy and Commerce Committee illustrates the complexity of not just the system, but the procurement process that led to having different contractors responsible for separate parts of a whole that were all dependent on the reliability of other parts.
"When you have five or six different people, each optimizing their part of the process, it's easy to pass a performance problem around in an infinite loop," says Michael Slaby, who headed the technology systems behind President Obama's 2008 and 2012 campaigns.
We tried to draw out each part of HealthCare.gov based on how 4 of its 55 total contractors described it. But if you prefer reading about their responsibilities, I've laid that out below.
CGI Federal is the contractor that has developed a portion of the federal exchange, the software application known as the Federally Facilitated Marketplace, or "FFM." It's the online marketplace for shopping after you create a secure account, so it's a combination of the website and a transaction processor for taking payments after you enroll.
Tools created by CGI include the e-mail that is sent to the user to confirm registration, the link that the user clicks on to activate the account, and the Web page the user lands on.
QSSI built the enterprise identity management (or EIDM), better known as the front door to HealthCare.gov. It's the registration management tool — the part that allows users to create secure accounts. You have to get past the front door before getting to the marketplace. According to administration officials, high traffic led the account creation, or front door, to bottleneck, which prevented the vast majority of users from accessing the marketplace. QSSI says the bottleneck happened because of a late-in-the-game decision to force users to create an account before getting to browse the plans.
QSSI also built the Data Services Hub that is not actually a hub because it doesn't store data. It's better described as a pipeline that transfers data — routing queries and responses between various trusted data sources. For example, after you enter information about yourself, things like citizenship must be verified. The pipeline directs queries to information sources, such as government databases that verify that information, and sends the responses back to the marketplace.
Data from the Internal Revenue Service, the Department of Homeland Security, Social Security and insurance carriers will be channeled by this pipeline.
Equifax is responsible for income verification data for those seeking financial assistance (subsidies) through the new health law. It does real-time verification of income and employment, and pipes it through the "hub." It verifies a user's eligibility for Medicaid and the Children's Health Insurance Program (CHIP), and for eligibility for tax credits and for reduced copays and deductibles for low-income applicants. This happens after a user gets through the front door, of course.
Serco's contract is to handle the paper applications. To date, the company has received about 8,000 paper applications. But, "Our challenges have included coping with the performance of the portal as that is our means of entering data just as it is for the consumer," Serco's John Lau says. The contract awarded had projected Serco to process 6 million paper applications by the end of March 2014.
*To be fair, the federal government isn't structured in a way that is inviting to the most expert technology minds. The way government hires for tech projects treats technology systems like single end products — a bridge, for example — that can be bought and built and left alone, instead of as services that roll out in stages, respond to users, and are continuously nurtured. For more on that topic, check out my Q&A with Mike Bracken, the United Kingdom's executive director of digital.

DES MOINES, Iowa (AP) — Fed up and ready to get off the sidelines, veteran Iowa Republicans are working to wrest control of the state GOP from the evangelicals, tea partyers and libertarians they blame for alienating longtime party loyalists.
Led by Iowa Gov. Terry Branstad, these Republicans want to grow the state party — one that ideological crusaders have shaped over the past few years — by bringing back into the fold pragmatic-minded voters while attracting more women and younger voters.
These Republicans say success would be Branstad winning re-election next fall and paving the way for a national GOP comeback in the 2016 presidential election by choosing a mainstream Republican in the leadoff presidential caucuses.
"What we need is someone who knows how to get things done, accomplish things," Branstad told the Associated Press recently. "My goal is to strengthen the party and to try to encourage people, new people, to participate and to show that I think the future for the party can be bright if we are welcoming — and if we really work."
The power struggle shaping up here has begun playing out across the nation. Some national Republican luminaries are blaming tea party figures like Texas Sen. Ted Cruz for demanding ideological purity, inciting the partial government shutdown and damaging perceptions of the party across the country.
In Iowa, it took the party two months to sell all the tickets to its annual fall fundraiser featuring Cruz, who led the failed effort to defund President Barack Obama's health care law. The event usually sells out quickly, and Branstad allies point to the sluggish pace as evidence that local GOP leaders are unhappy — and ready for a change.
Others dispute that, and accuse Branstad's backers of trying to weaken the party's conservative base.
"It's really unfortunate that a small few who are loud are trying to speak for the grassroots," said Tamara Scott, a Republican National Committee woman and outspoken Christian conservative who speaks highly of Cruz.
For decades, pro-business, economic conservatives like Branstad controlled the Iowa GOP. In the 1980s, the evangelical wing injected new energy. But those Republicans also rallied behind presidential candidates who ultimately lost the party's nomination, raising questions of whether Iowa Republicans were reflective of the GOP nationally.
In 2000, George W. Bush broke the mold, knitting business and Christian conservatives together to win the caucuses en route to the White House.
But big budget deficits under Bush turned off centrists, and the war in Iraq roused supporters for former Texas Rep. Ron Paul. That left evangelicals and Paul-type libertarians — many who would also later identify with the tea party — the most engaged Republicans in Iowa. They flexed their power in 2008, choosing as their caucus winner Arkansas Gov. Mike Huckabee, whose dominant Christian conservative profile further alienated mainstream Republicans.
By 2010, the Iowa GOP was so weak that it recruited the long-retired former governor, Branstad, to run again. This pragmatic, not ideological, Republican beat a well-known social conservative in a tough primary before unseating the unpopular Democratic incumbent. Branstad backers viewed his victory as the start of a complete reclaiming of the party.
Then came the 2012 Iowa caucus debacle.
The state GOP initially declared Mitt Romney the winner. Three weeks later, the party drew ridicule when it said former Pennsylvania Sen. Rick Santorum — a social conservative — had actually received the most votes.
Meanwhile, insurgent tea party conservatives and Paul supporters from his two failed presidential campaigns worked at the precinct level to seize the state GOP committee and chairmanship. They succeeded.
A.J. Spiker, a Paul backer, became the state party chairman. Since then, he's faced criticism from activists for weak fundraising. Records show that the party was raising more than $40,000 a month four years ago and now is raising less than $30,000 per month. Spiker dismisses the criticisms and the Branstad effort as nothing more than typical squabbling.
"We are in a period of some disagreement within the party. But I think that is happening nationally," Spiker said.
Branstad's allies have had enough. They hope to drive disaffected Republicans back into the party's grassroots, starting with the midterm caucuses in January where party activists will choose delegates who will decide the GOP's direction heading into 2016.
"If the establishment wants to take over, they have to show up," said Doug Gross, a longtime Branstad adviser. "And frankly we haven't."
The effort doesn't stop with the caucuses.
Branstad is publicly neutral in the U.S. Senate primary here, but Lt. Gov. Kim Reynolds is publicly backing Joni Ernst — a state senator from rural southwest Iowa — in a crowded field.
Reynolds says her endorsement is "not just in name only," and plans to campaign and raise money for Ernst. in hopes that the six-candidate Senate field's only woman could help the party attract more women voters next fall, and to the 2016 caucuses.
Oskaloosa lawyer Diane Crookham Johnson is among those Republicans Branstad wants back.
The state party's chief fundraiser in 2000, Johnson supports abortion rights, but dropped out of party leadership after growing frustrated with what she saw as increasing rigidity on social issues.
But Johnson has been contacted by Ernst and rival Mark Jacobs, and likes what she's starting to hear.
"They want to know where I'm at," she said "And that's a good sign."

Microsoft Surface Unit Volume Doubled In Most Recent Quarter
Microsoft today reported that its Surface line of tablets had revenue of $400 million in the most recent quarter. On its earnings call, the company stated that in the most recent quarter (fiscal Q1, 2014), Surface unit volume doubled from the prior quarter (fiscal Q4, 2013). I confirmed the fact with Microsoft directly, following the statement.
It’s an interesting fact, because it underscores that Surface is at once growing, but that it also had a weak summer sales season. For the fiscal year that recently ended for Microsoft, total Surface revenue totaled $853 million. Given that the $400 million figure for the most recent quarter (which was not part of that $853 million sum) was essentially half the former total, it can be deduced — in conjunction with the doubled unit volume — that Microsoft’s tablet line sold slowly during the summer.
That’s not unexpected, of course, but it’s important to keep in mind where Surface is coming from, so that we can put its later figures into context.
Microsoft noted that in the most recent quarter, there was some hesitation among potential Surface Pro purchasers, as the Surface Pro 2 was on the horizon. That pent-up demand could skew Surface revenue higher in the current quarter that will include the release of the Surface Pro 2, the Surface 2, and the holiday sales cycle.
In a call, Microsoft declined to forecast Surface revenue for the coming quarter.
So we’ll have to do it. I think that $600 million will be the absolute lower bound of “not terrible”; $800 million will be solid; and a $1 billion tally will be a win. Your move, Microsoft.

Tunable electrical behavior not previously realized in conventional devices
As electronics approach the atomic scale, researchers are increasingly successful at developing atomically thin, virtually two-dimensional materials that could usher in the next generation of computing. Integrating these materials to create necessary circuits, however, has remained a challenge.
Northwestern University researchers have now taken a significant step toward fabricating complex nanoscale electronics. By integrating two atomically thin materials molybdenum disulfide and carbon nanotubes they have created a p-n heterojunction diode, an interface between two types of semiconducting materials.
"The p-n junction diode is among the most ubiquitous components of modern electronics," said Mark Hersam, Bette and Neison Harris Chair in Teaching Excellence in the Department of Materials Science and Engineering at Northwestern's McCormick School of Engineering and Applied Science and director of the Northwestern University Materials Research Center. "By creating this device using atomically thin materials, we not only realize the benefits of conventional diodes but also achieve the ability to electronically tune and customize the device characteristics. We anticipate that this work will enable new types of electronic functionality and could be applied to the growing number of emerging two-dimensional materials."
The isolation over the past decade of atomically thin two-dimensional crystals such as graphene, a single-atom-thick carbon lattice has prompted researchers to stack two or more distinct two-dimensional materials to create high-performance, ultrathin electronic devices. While significant progress has been made in this direction, one of the most important electronic components the p-n junction diode has been notably absent.
Among the most widely used electronic structures, the p-n junction diode forms the basis of a number of technologies, including solar cells, light-emitting diodes, photodetectors, computers, and lasers.
In addition to its novel electronic functionality, the p-n heterojunction diode is also highly sensitive to light. This attribute has allowed the authors to fabricate and demonstrate an ultrafast photodetector with an electronically tunable wavelength response.
The research, "Gate-Tunable Carbon Nanotube-MoS2 Heterojunction p-n Diode," was published October 21 in the Proceedings of the National Academy of Sciences.

CP Rail's profit jumps as freight revenue rises, costs fall
(Reuters) - Canadian Pacific Railway
The U.S.-listed shares
Canada's largest rail operator, Canadian National Railway Co
CP said operating ratio improved 820 basis point to 65.9 percent in the quarter. The ratio improved by 80 basis points to 59.8 percent for Canadian National Railway.
Operating ratio is a key barometer of efficiency in the railroad industry and is the percentage of revenue needed to maintain operations.
CP said Chief Financial Officer Brian Grassby will be retiring but would remain till the end of the year.
Net income climbed to C$324 million ($315 million), or C$1.84 per share, from C$224 million, or C$1.30 per share, a year earlier. Excluding items, the company earned C$1.88 per share.
Costs fell 6 percent.
Revenue rose 6 percent to C$1.5 billion.
Analysts had expected earnings of C$1.72 per share, according to Thomson Reuters I/B/E/S.
CP's shares closed at C$134.74 on the Toronto Stock Exchange on Tuesday. They ended at $130.96 on the New York Stock Exchange.

Boeing boosts 2013 forecast as Q3 profit soars
Washington (AFP) - Boeing raised its 2013 earnings forecast Wednesday after third-quarter profits soared, saying it would boost production of its flagship 787 Dreamliner aircraft.
Net earnings totaled $1.16 billion for the July-September quarter, an increase of 12 percent from $1.03 billion in the same period in 2012, the US aerospace and defense giant said.
Earnings per share came in at $1.51 compared with $1.35 a year ago.
Adjusted earnings per share, excluding certain pension expenses, increased 16 percent to $1.80, well above Wall Street analysts' average estimate of $1.55.
Revenues also beat expectations, rising 11 percent to $22.13 billion, reflecting higher commercial airplane deliveries.
"Consistently strong operating performance is driving higher earnings, revenue and cash flow as we deliver on our record backlog and return increased value to shareholders," said Jim McNerney, Boeing's chairman, president and chief executive.
Boeing raised its 2013 core earnings outlook to a range of between $6.50 and $6.65 per share, from the prior estimate of $6.20-$6.40 range. It maintained its revenue forecast of $83-86 billion.
Investors cheered, pushing Boeing shares to new all-time highs despite an overall lower market. The Dow component's stock was up 4.9 percent at $128.44 in late-afternoon New York trade, after climbing as high as $129.99.
In the year to date, Boeing shares have spiked about 60 percent, after trading steadily in the $70 range in 2012.
Boeing said it expected to deliver 635 to 645 new commercial aircraft in the year, including more than sixty 787s, at an operating margin revised to above 10 percent, an increase of a half percentage point.
The Chicago-based company, which employs more than 170,000 people in the US and in 70 countries, said it had third-quarter operating cash flow before voluntary pension contributions of $4.31 billion, up from $2.35 billion a year ago.
It also had a record $415 billion order backlog, including $27 billion net orders booked during the quarter.
Third-quarter profits from its Commercial Airplanes subsidiary soared 40 percent to $1.62 billion, while revenues rose 15 percent to $13.99 billion.
Despite technical glitches that have plagued Boeing's new 787 Dreamliner , the company reported "continued strong demand" for its cutting-edge plane, which entered service two years ago.
The company said it planned to increase its 787 production rate for 2016 to 12 airplanes per month from 10, and would raise that 14 airplanes per month before the end of the decade.
But McNerney, in a conference call with analysts, expressed dissatisfaction with the 787's performance.
"Improving dispatch reliability of the 787 is at the top of our priorities," he said, referring to the ratio of the number of flights delayed because of technical problems to the total number of flights.
Boeing booked 200 net aircraft orders in the third quarter. Deliveries accelerated to 170 airplanes from 149 a year ago, as the pace of 787 deliveries nearly doubled.
Commercial Airplanes had a backlog of nearly 4,800 airplanes valued at $345 billion.
Headwinds from US cutbacks in defense spending amid a protracted Washington budget battle that forced sharp "sequestration" automatic cutbacks beginning in March appeared to impact Boeing's Defense, Space & Security subsidiary.
Profits in the smaller defense unit fell 19 percent to $673 million, led by a 48 percent fall in earnings from military aircraft. Boeing said that its military aircraft unit's operating margin fell 6.2 percent, in part reflecting one-time charges on the F-15 and C-17 programs.
The Defense unit had an order backlog of $70 billion, with 38 percent of that representing orders from international customers.
"Despite the uncertainty of the US defense market, overall our customer-focused business strategies and disciplined execution on our programs are producing the results we expect, McNerney said.

DANVERS, Mass. (AP) — A well-liked teacher was found slain in woods behind this quiet Massachusetts town's high school, and a 14-year-old boy who was found walking along a state highway overnight was charged with killing her.
Blood found in a second-floor school bathroom helped lead investigators to the body of Colleen Ritzer, a 24-year-old math teacher at Danvers High School who was reported missing when she didn't come home from work on Tuesday, Essex District Attorney Jonathan Blodgett said.
"She was a very, very respected, loved teacher," Blodgett said.
The suspect, Philip Chism, was arraigned on a murder charge Wednesday and ordered held without bail. The teenager, described by classmates as soft-spoken and pleasant, also did not come home from school the day before and was spotted walking along Route 1 in the neighboring town of Topsfield at about 12:30 a.m. Wednesday.
Officials didn't release a cause of death and haven't discussed a motive in the killing.
A court filing said Ritzer and Chism were known to each other from the high school, but it did not elaborate. The arrest was made based on statements by the suspect and corroborating evidence at multiple scenes, investigators said in court documents.
Ritzer's family said they are mourning the death of their "amazing, beautiful daughter and sister."
"Everyone that knew and loved Colleen knew of her passion for teaching and how she mentored each and every one of her students," the family said in a statement provided by her uncle Dale Webster.
At his arraignment in adult court in Salem, Chism's defense attorney argued for the proceeding to be closed and her client to be allowed to stay hidden because of his age. The judge denied the request. The lawyer, Denise Regan, declined to comment outside court. No statement had been released from his family by Wednesday evening.
The tall, lanky teenager had moved to Massachusetts from Tennessee before the start of the school year and was a top scorer on the school's junior varsity soccer team, said Kyle Cahill, a junior who also plays soccer. He said the team had been wondering where Chism was when he skipped a team dinner Tuesday night.
"We're all just a family. It just amazes me really," Cahill said. "He wasn't violent at all. He was really the opposite of aggressive."
Ritzer had a Twitter account where she gave homework assignments, encouraged students and described herself as a "math teacher often too excited about the topics I'm teaching."
She was a 2011 graduate of Assumption College in Worcester, a school spokeswoman said Wednesday. She graduated magna cum laude with a bachelor of arts degree in math, a minor in psychology and a secondary education concentration, according to the college's 2011 commencement program.
One of her former students, Chris Weimert, 17, said she was a warm, welcoming person who would stand outside her classroom and say hello to students she didn't teach. He said she had been at the school for two years.
"She was the nicest teacher anyone could ever have. She always had a warm smile on her face," he said.
Ryan Kelleher, a senior, said students related to the young teacher, who liked to wear jeans and UGG boots just like the teenagers she taught. Kelleher, who also plays soccer, said the arrest of the soft-spoken Chism didn't make sense to him.
"From what I know about him and seeing him every day, it just doesn't add up that he would do such a thing, unless this was all an act to fool somebody," the 17-year-old said.
Ritzer lived at home with her 20-year-old brother and her sister, a high school senior. The close-knit family was often outside, barbecuing, spending time together and enjoying each other's company, neighbors said.
Mary Duffy has lived next door to the Ritzers in the suburban neighborhood in Andover since the family moved there more than two decades ago. She had known Colleen Ritzer from the time she was a baby and said the Ritzers' oldest child had just one life ambition: to be a high school math teacher.
"All I ever heard is that she loved her job," Duffy said.
All public schools in Danvers, about 20 miles north of Boston, were closed Wednesday.
The Boston Red Sox had a moment of silence for Ritzer Wednesday before Game 1 of the World Series.
Hundreds turned out for a candlelight vigil Wednesday evening on the parking lot of the school. Many wore pink, Ritzer's favorite color. They prayed and sang and, at the end of the vigil, they placed their candles along with some stuffed animals in the middle of a ring they have formed for the gathering.
"She supported all of us. We should be there to support her," said Danvers senior Courtney Arnoldy, 18, who had Ritzer for a teacher.
Ritzer is the second teacher allegedly killed by a student in the U.S. this week. A Sparks, Nev., middle school teacher was allegedly shot by a 12-year-old student on Monday.

Japan's Abe: to use extra tax revenue, not new debt, for stimulus spending
TOKYO (Reuters) - Japanese Prime Minister Shinzo Abe said on Thursday he plans to use higher-than-expected tax revenue to fund economic stimulus spending rather than relying on issuing new debt.
Abe was speaking in the upper house budget committee.
The government will announce in early December details of a 5 trillion yen ($51 billion) economic stimulus package meant to offset the drag from an increase in the sales tax next April. ($1 = 97.2900 Japanese yen)

Birthing a new breed of materials

Where two different materials meet on the atomic level, a new material can be born that is neither one nor the other. The two parent materials do not mix they remain distinct from one another but their marriage begets a strange child with properties unlike those of either parent. These so-called interfacial materials are considered to be a breed of materials in their own right, and, thanks to recent technological advances that allow them to be fabricated in the laboratory, their real-world properties can now be explored.
A discussion of new insights into these interfacial materials, as well as some of the novel properties expected of them, will be given by materials scientist Chang-Beom Eom, Theodore H. Geballe Professor and Harvey D. Spangler Distinguished Professor at the University of Wisconsin at Madison, at the AVS 60th International Symposium and Exhibition, held Oct. 27-Nov. 1, 2013, in Long Beach, Calif.
"Each new interfacial material presents unexplored territory, in much the same way as the discovery of a new bulk material," Eom said. Researchers can use analogies to compare a new interfacial material to bulk materials with similar properties, he continued, "but there is always something unique about the new interfacial material that holds surprises" for the people studying it.
For one such material is born from the marriage between LaAlO3 (lanthanum aluminum oxide) and SrTiO3 (strontium titanium oxide). The parent compounds are insulating, meaning they do not conduct electricity; but the interface where they meet is conducting. Another interfacial material, made of different parent compounds, holds promise for being a topological insulator, a material that allows electrons to move along its surface in a way that fundamentally protects them from the usual defects and imperfections of a conducting substance.
Size is one of the bigger advantages of these new substances compared to bulk materials. Since their unusual behavior is confined to the atom-thin space between two compounds, interfacial materials could one day be used to make tiny devices that consume less power, Eom said.
Theorists had predicted the existence of many of these substances, but modern-day techniques for growing one thin film on top of another with interfaces that are atomically distinct from each other have now made it possible to create these materials in the laboratory.
"Advances over the last ten years in both materials experiment and theory have come together to provide our first real opportunities to broadly explore interfacial materials," Eom said. With a deeper understanding of their unusual properties, Eom continued, researchers may one day be able to customize the materials, combining theory and experiment to design interfacial materials for nanoscale applications.
