PAP's Koh Poh Koon describes himself as a man who wants to get things done






SINGAPORE: Someone who wants to get things done and done effectively.

That's how Dr Koh Poh Koon describes himself, believing these traits can help him contribute as the People's Action Party's (PAP) candidate for the Punggol East by-election.

Despite being a new face in the constituency, Dr Koh feels that many residents have warmed up to him.

Despite having only been introduced to Punggol East voters recently, Dr Koh already looks comfortable interacting with the residents. That's because he said, communicating with people comes as second nature given his profession as a surgeon.

"My job as a doctor has allowed me to really be connecting to strangers that just walk into my clinic and within five minutes we've established a rapport.

"They put their lives in my hands to operate for them so I think building up a rapport with people and gaining their trust is something that comes naturally to me because of my training and my profession.

"And I think my personality and disposition does make it easier as well. Be sincere, be yourself, never be a different person, life gets miserable when you put up a facade.

"Second thing, be sincere and ernest and I think people will be able to listen and they can feel it and that much I learned from my patients".

Dr Koh may have been a grassroots volunteer for the last 11 years. But a recent meeting with a low-income Punggol East resident convinced him that he has made the right choice to stand as a PAP candidate in this by-election.

"He said doctor, we don't want handouts, help us get a breakthrough, break our poverty cycle and that really struck me that helping people really goes beyond giving handouts. It's about putting in place programmes that give people a break in life, giving people a future, that there's hope."

Connecting with the residents is of utmost importance to Dr Koh, prompting him to share his humble childhood experience.

"The way to understand a person is to know what he's made of, you need to know where he came from and that's the way of putting forward my life for residents to understand what makes me tick and I think that has achieved some resonance with the residents."

Dr Koh already has plans to provide new services such as daycare for the elderly and health screening programmes within a soon-to-be built community centre.

Online courses need human element




Online courses are proliferating, says Douglas Rushkoff, but will really succeed when they bring humanity to learning process




STORY HIGHLIGHTS


  • Douglas Rushkoff: Education is under threat, but online computer courses are not to blame

  • He says education's value hard to measure; is it for making money or being engaged?

  • He says Massive Open Online Courses lack human exchange with teachers

  • Rushkoff: MOOCs should bring together people to share studies, maintain education's humanity




Editor's note: Douglas Rushkoff writes a regular column for CNN.com. He is a media theorist and the author of "Program or Be Programmed: Ten Commands for a Digital Age" and "Life Inc.: How Corporatism Conquered the World, and How We Can Take It Back." He is also a digital literacy advocate for Codecademy.com. His forthcoming book is "Present Shock: When Everything Happens Now."


(CNN) -- Education is under threat, but the Internet and the growth of Massive Open Online Courses are not to blame.


Like the arts and journalism, whose value may be difficult to measure in dollars, higher education has long been understood as a rather "soft" pursuit. And this has led people to ask fundamental questions it:


What is learning, really? And why does it matter unless, of course, it provides a workplace skill or a license to practice? Is the whole notion of a liberal arts education obsolete or perhaps an overpriced invitation to unemployment?



Douglas Rushkoff

Douglas Rushkoff



The inability to answer these questions lies at the heart of universities' failure to compete with new online educational offerings -- the rapidly proliferating MOOCs -- as well as the failure of most Web-based schools to provide a valid alternative to the traditional four-year college.


Education is about more than acquiring skills.


When America and other industrialized nations created public schools, it was not to make better workers but happier ones. The ability to read, write and think was seen as a human right and a perquisite to good citizenship, or at least the surest way to guarantee compliant servitude from the workers of industrial society. If even the coal miner could spend some of his time off reading, he stood a chance of living a meaningful life. Moreover, his ability to read the newspaper allowed him to understand the issues the day and to vote intelligently.


What we consider basic knowledge has grown to include science, history, the humanities and economics. So, too, has grown the time required to learn it all. While the modern college might have begun as a kind of finishing school, a way for the sons of the elite to become cultured and find one another before beginning their own careers, it eventually became an extension of public school's mandate. We go to college to become smarter and more critical thinkers while also gaining skills we might need for the work force.



Accordingly, we all wanted our sons and daughters to go to college until recently. The more of us who could afford it, the better we felt we were doing as a society. But the price of education has skyrocketed, especially in the tiny segment of elite schools. This has led to the widespread misperception that a good college education is available only to those willing to take on six-figure debt.


Worse, in making the calculation about whether college is "worth it," we tend to measure the cost of a Harvard education against the market value of the skills acquired. Did my kid learn how to use Excel? If not, what was the point?


To the rescue come the MOOCs, which offer specific courses, a la carte, to anyone with a credit card; some even offer courses for free.


Following the model of University of Phoenix, which began offering a variety of "distance learning" in 1989, these newer Web sites offer video lectures and forums to learn just about anything, in most cases for a few hundred dollars a class. MOOCs have exploded in the past few years, enrolling millions of students and sometimes partnering with major universities.








For pure knowledge acquisition, it's hard to argue against such developments, especially in an era that doesn't prioritize enrichment for its own sake. But it would be a mistake to conclude that online courses fulfill the same role in a person's life as a college education, just as it would be an error to equate four years of high school with some online study and a GED exam.


Don't get me wrong: I have always been a fan of online education -- but with a few important caveats.


First off, subjects tend to be conveyed best in what might be considered their native environments. Computers might not be the best place to simulate a live philosophy seminar, but they are terrific places to teach people how to use and program computers.


Second, and just as important, computers should not require the humans using them to become more robotic. I recently read an account from an online lecturer about how -- unlike in a real classroom -- he had to deliver his online video lectures according to a rigid script, where every action was choreographed. To communicate effectively online, he needed to stop thinking and living in the moment. That's not teaching; it's animatronics.


Online learning needs to cater to human users. A real instructor should not simply dump data on a person, as in a scripted video, but engage with students, consider their responses and offer individualized challenges.


The good, living teacher probes the way students think and offers counterexamples that open pathways. With the benefit of a perfect memory of student's past responses, a computer lesson should also be able to identify some of these patterns and offer up novel challenges at the right time. "How might Marx have responded to that suggestion, Joe?"


Finally, education does not happen in isolation.


Whether it's philosophy students arguing in a dorm about what Hegel meant, or fledgling Java programmers inspecting one another's code, people learn best as part of a cohort. The course material is almost secondary to the engagement. We go to college for the people.


Likewise, the best of MOOCs should be able bring together ideal, heterogeneous groupings of students based on their profiles and past performance, and also create ample opportunities for them to engage with one another in the spirit of learning.


Perhaps this spirit of mutual aid is what built the Internet in the first place. Now that this massive collaborative learning project has succeeded, it would be a shame if we used it to take the humanity out of learning altogether.

House passes $50.7 billion Sandy relief bill

FILE - In this Oct. 30, 2012, file photo, a man walks with his dog to a National Guard vehicle after leaving his flooded home at the Metropolitan Trailer Park in Moonachie, N.J., in the wake of Superstorm Sandy. The storm drove New York and New Jersey residents from their homes, destroyed belongings and forced them to find shelter for themselves - and for their pets, said owners, who recounted tales of a dog swimming through flooded streets and extra food left behind for a tarantula no one was willing to take in. (AP Photo/Craig Ruttle, File) / Craig Ruttle

The House of Representatives today passed a $50.7 billion bill to provide funds for Hurricane Sandy relief as well as other natural disasters. The vote was 241 to 180, with 179 Republicans and one Democrat voting no.

The bill will now move to the Senate, where it is expected to be passed by lawmakers after the new session begins on January 22, though it's possible it could be passed by voice vote this week. It is then expected to be quickly signed into law by President Obama.

The package was divided into two parts: A $17 billion bill for immediate recovery from Sandy, and another $33.7 billion amendment for long-term recovery and investment to limit the damage from similar events in the future. The October storm is believed to be responsible for 140 deaths and billions of dollars in damage centered in New York, New Jersey and Connecticut. It damaged or destroyed hundreds of thousands of homes and businesses and knocked out transit systems and power grids.

The package provides more than $16 billion for the New York and New Jersey transit systems as well as more $16 billion for Housing and Urban Development funding for recovery from Sandy and other disasters. Other funding goes to the Federal Emergency Management Agency's disaster relief aid fund and to Army Corps of Engineers projects to limit future damage. Funding is also authorized for repairs by the Coast Guard, Federal Highway Administration and Veterans Affairs Department.

Lawmakers from the Northeast criticized southern Republican lawmakers who had sought to reduce the size of the package or require that funding be offset with an across the board cut to discretionary spending. An amendment from Rep. Mick Mulvaney, R-S.C., that would have offset the funding with spending cuts failed 162 yeas to 258 nays earlier in the day, and the Republican-led House Rules Committee blocked efforts to reduce the size of the package.

"We are asking, we are pleading and we shouldn't have to beg for money for the Northeast, to be able to survive this tragedy that hit us," said Rep. Rosa Delauro, D-Conn., who added: "I might remind my colleague from Louisiana that between Rita, Wilma and Katrina, this institution appropriated $133.9 billion in disaster relief."

Critics of the bill derided it as "an excuse for a grab-bag of spending, having nothing to do with emergency relief," in the words of Rep. Tom McClintock, R-Calif.

The Senate passed a $60 billion Sandy relief bill before the end of the last Congress, but House Speaker John Boehner, R-Ohio, declined to schedule a House vote on that measure in the wake of the contentious vote on "fiscal cliff" legislation. That decision prompted harsh criticism from northeastern lawmakers, including Rep. Peter King, R-N.Y., and Gov. Chris Christie, R-N.J., forcing Boehner to hastily schedule today's vote in addition to $9.7 billion in flood relief that was passed Jan. 4.

NY Passes Nation's Toughest Gun Law













Today New York became the first state to pass a gun control law -- the toughest in the nation -- since the Sandy Hook Elementary School shooting massacre last month.


Acting one month and a day since the rampage killing that left 20 first-graders and six educators dead, Gov. Andrew Cuomo signed the bill into law shortly after 5 p.m.


Called the New York Safe Act, the law includes a tougher assault weapons ban that broadens the definition of what constitutes an assault weapon, and limits the capacity of magazines to seven bullets, down from 10. The law also requires background checks of ammunition and gun buyers, even in private sales, imposes tougher penalties for illegal gun use, a one-state check on all firearms purchases, and programs to cut gun violence in high-crime neighborhoods.


As he signed the bill into law, Cuomo said it was not only "the first bill" but the "best bill."


"I'm proud to be a New Yorker, because New York is doing something, because we are fighting back, because, yes, we've had tragedies, and yes, we've had too many innocent people lose their lives, and yes, it's unfortunate that it took those tragedies to get us to this point, but let's at least learn from what's happened, let's at least be able to say to people, yes, we went through terrible situations, but we saw, we learned, we responded, and we acted, and we are doing something about it," Cuomo said. "We are not victims.

'The View' on NRA Shooting App: Think It Out Watch Video







"You can overpower the extremists with intelligence and with reason and with commonsense," Cuomo continued, "and you can make this state a safer state."


New York's law also aims to keep guns out of the hands of those will mental illness. The law gives judges the power to require those who pose a threat to themselves or others get outpatient care. The law also requires that when a mental health professional determines a gun owner is likely to do harm, the risk must be reported and the gun removed by law enforcement.


The legislation also includes what is called a "Webster provision," named for the two firefighters ambushed on Christmas Eve in Webster, N.Y. The measure would mandate a life sentence with no chance of parole for anyone who kills a first responder.


The National Rifle Association issued a statement after the bill's signing, saying it was "outraged at the draconian gun control bill that was rushed through ... late Monday evening."


"Gov. Andrew Cuomo and the New York State Legislature orchestrated a secretive end-run around the legislative and democratic process and passed sweeping anti-gun measures with no committee hearings and no public input," the statement read. "These gun control schemes have failed in the past and will have no impact on public safety and crime. Sadly, the New York Legislature gave no consideration to that reality. While lawmakers could have taken a step toward strengthening mental health reporting and focusing on criminals, they opted for trampling the rights of law-abiding gun owners in New York, and they did it under a veil of secrecy in the dark of night. The legislature caved to the political demands of a governor and helped fuel his personal political aspirations."

Tennis: Ice-cool Murray crushes Haase at Australian Open






MELBOURNE: Andy Murray brushed aside Dutchman Robin Haase in a clinical display to progress smoothly to the second round of the Australian Open.

The third-seeded Scot had few problems with the 53rd-ranked Haase, winning 6-3, 6-1, 6-3 in 1hr 37min in warming temperatures on Rod Laver Arena.

Murray, who broke through for his first Grand Slam title at last year's US Open, was always in charge of his opening match breaking Haase's service eight times in a dominant display.

"It was a good start and it was nice to win in straight sets, it was the hottest day of the tournament so far," Murray said at courtside.

"It took a little while to get used to that and the court was playing much quicker because of it."

Murray, 25, has twice been runner-up at the Australian Open. He is drawn to face 17-time Grand Slam champion Roger Federer in the semi-finals and possibly defending champion Novak Djokovic in the final.

The Scot hit 25 winners mixed with 20 unforced errors, while Haase gave up 35 unforced errors.

Murray broke the erratic Dutchman's serve three times to take the opening set in 41 minutes helped by his superior accuracy. Meanwhile Haase frequently over-hit his volleys and failed to put consistent pressure on the third seed.

Murray was broken as he attempted to serve out for the set, putting a weak sliced backhand into the net, but it was only a temporary setback as the Scot broke Haase's serve next game for the set.

Murray, with an iced towel around his neck at changeovers to cope with the heat, took a grip on the match and he raced through the second set in 26 minutes with two more service breaks, conceding just 12 points.

And the third seed broke the wilting Dutchman's opening service game in the final set as he surged towards victory.

Murray reeled off another break in the fifth game, but lost his own serve for only the second time in the match at 4-2. But he again broke Haase's serve to take the match when the Dutchman overhit a forehand.

Clarence Thomas ends seven-year silence

STORY HIGHLIGHTS


  • Clarence Thomas known for remaining quiet during oral arguments

  • On Monday, he joked about lawyers educated at Yale, his alma mater

  • Current Supreme Court known as 'hot bench' for the rhetorical scrum during arguments




Washington (CNN) -- It was just a few words and a joke at that. But Supreme Court Justice Clarence Thomas broke his seven-year long silence on Monday when he spoke at oral arguments.


He made fun of lawyers from Yale, his law school alma mater.


Thomas has become known for rarely commenting on cases from the bench, another reflection of the complex and often misunderstood personality of the court's only African-American jurist.


On Monday, the justices were hearing an argument about the state of Louisiana's delay in paying for counsel for a death penalty defendant. Should that count against the state for the purposes of the right to a speedy trial?


A lawyer for the state was making the case for the inmate's appointed counsel, saying the woman was "more than qualified" and "very impressive."


"She was graduate of Yale Law School, wasn't she?" said Justice Antonin Scalia in apparent support, noting another member of the legal team went to Harvard.


The next words were hard to hear in the back-and-forth between the justices. But Thomas made a joke about the competence of Yale lawyers when compared to their Harvard colleagues, according to two witnesses.

The official transcript released by the court does not capture the flavor of the colorful exchange. But the lawyer arguing before the court was apparently not pleased.


"I would refute that, Justice Thomas," said Carla Sigler, the assistant district attorney in Lake Charles, Louisiana.


The rest of the time, Thomas kept his own counsel as he is known to do.


"One thing I've demonstrated often in 16 years is you can do this job without asking a single question," he recalled in a speech five years ago.


Written opinions remain the main way the court expresses itself. But the current court is known as a "hot bench" for the busy back-and-forth rhetorical scrum during arguments.


Eight of the justices compete for time to make their questions and views known.


Thomas does occasionally speak from the bench when announcing opinions he has written, but before arguments commence.


Off the bench in friendly audiences, he can be gregarious, inquisitive and often self-reflective. He has a booming voice, and his hearty laugh is easily recognizable.


Some scholars have said Thomas' aversion to talking has reached epic heights.


A study of transcripts by Timothy Johnson of the University of Minnesota found in the past four decades, no justice besides Thomas had failed to speak at least once during an entire 12-month term.


The last time he spoke was February 22, 2006, during a capital appeal.

Hillary Clinton to testify on Benghazi Jan. 23

Secretary of State Hillary Rodham Clinton will testify Jan. 23 before the House Foreign Affairs Committee about the deadly Sept. 11 assault on the U.S. mission in Libya.



That's the word from Rep. Ed Royce, chairman of the panel. He said in a statement late Monday that Clinton will answer questions about the raid that killed U.S. Ambassador Chris Stevens and three other Americans in Benghazi.

Clinton had been scheduled to testify last month but she suffered a concussion when she fell during an illness. She was later hospitalized with a blood clot in her head.

She's also expected to testify before the Senate Foreign Relations Committee around the same time as her House testimony. That date has not been announced by the committee.

She has planned to step down and President Barack Obama has nominated Sen. John Kerry to replace her.

Armstrong Admits Doping in Tour, Sources Say













Lance Armstrong today admitted to Oprah Winfrey that he used performance enhancing drugs to win the Tour de France, sources told ABC News.


A goverment source tells ABC News that Armstrong is now talking with authorities about paying back some of the US Postal Service money from sponsoring his team. He is also talking to authorities about confessing and naming names, giving up others involved in illegal doping. This could result in a reduction of his lifetime ban, according to the source, if Armstrong provides substantial and meaningful information.


Armstrong made the admission in what sources describe as an emotional interview with Winfrey to air on "Oprah's Next Chapter" on Jan. 17.


The 90-minute interview at his home in Austin, Texas, was Armstrong's first since officials stripped him of his world cycling titles in response to doping allegations.


Word of Armstrong's admission comes after a Livestrong official said that Armstrong apologized today to the foundation's staff ahead of his interview.


The disgraced cyclist gathered with about 100 Livestrong Foundation staffers at their Austin headquarters for a meeting that included social workers who deal directly with patients as part of the group's mission to support cancer victims.


Armstrong's "sincere and heartfelt apology" generated lots of tears, spokeswoman Katherine McLane said, adding that he "took responsibility" for the trouble he has caused the foundation.

Lance Armstrong Doping Charges: Secret Tapes Watch Video





McLane declined to say whether Armstrong's comments included an admission of doping, just that the cyclist wanted the staff to hear from him in person rather than rely on second-hand accounts.


Armstrong then took questions from the staff.


Armstrong's story has never changed. In front of cameras, microphones, fans, sponsors, cancer survivors -- even under oath -- Lance Armstrong hasn't just denied ever using performance enhancing drugs, he has done so in an indignant, even threatening way.


Armstrong, 41, was stripped of his seven Tour de France titles and banned from the sport for life by the U.S. Anti-Doping Agency in October 2012, after allegations that he benefited from years of systematic doping, using banned substances and receiving illicit blood transfusions.


"Lance Armstrong has no place in cycling and he deserves to be forgotten in cycling," Pat McQuaid, the president of the International Cycling Union, said at a news conference in Switzerland announcing the decision. "This is a landmark day for cycling."


The U.S. Anti-Doping Agency issued a 200-page report Oct. 10 after a wide-scale investigation into Armstrong's alleged use of performance-enhancing substances.


Armstrong won the Tour de France from 1999 to 2005.


According to a source, speaking to ABC News, a representative of Armstrong's once offered to make a donation estimated around $250,000 to the agency, as "60 Minutes Sports" on Showtime first reported.


Lance Armstrong's attorney Tim Herman denied it. "No truth to that story," Herman said. "First Lance heard of it was today. He never made any such contribution or suggestion."


Armstrong, who himself recovered from testicular cancer, created the Lance Armstrong Foundation (now known as the LIVESTRONG Foundation) to help people with cancer cope, as well as foster a community for cancer awareness. Armstrong resigned late last year as chairman of the LIVESTRONG Foundation, which raised millions of dollars in the fight against cancer.

Benefits of emissions cuts kick in only next century









































Are we the altruistic generation? Do we care what happens to our grandchildren, and to their children? Or are we with Groucho Marx when he said: "Why should I care about future generations? What have they ever done for me?"











A new study of climate change lays out in detail why this matters. According to its author, Nigel Arnell of the University of Reading, UK, the unpalatable truth is that even rapid action now to curb greenhouse gas emissions would have only a "negligible effect by 2030, and the benefits in 2050 would remain small". The big dividend – cooler temperatures, fewer floods and droughts and better crop yields, compared to carrying on as we are – would only become clear by about 2100.












Arnell and colleagues used climate models to look at how different policies to curb greenhouse gases would affect temperature, sea levels, crop yields and the incidence of droughts and floods. Two findings emerged. The first is that lags in the climate system mean the real benefits of cutting emissions will only show up late this century. This, says Arnell, underlines that there is a lot of global warming "in the pipeline" that cannot now be prevented.












But the study also shows that tackling climate change early brings big rewards. Arnell compared a policy of letting emissions peak in 2016 and then cutting them by 2 per cent a year with one that delays the peak till 2030 and then cuts by 5 per cent a year. He found that both restricted warming in 2100 to about 2 °C, but the climate disruption over the next century would be much less with the early start. Coastal flooding from sea-level rise in particular would be much reduced. This, he told New Scientist, contradicts a common view that drastic action to curb warming should wait for renewable energy to become cheaper.













"Arnell has shown just how crucial the emissions pathway we take today will be for our children and grandchildren," said Dave Reay, geoscientist at the University of Edinburgh, UK. Bill McGuire of University College London agrees: "It shows taking effective action now is far better than putting it off until later."












It's a shame, then, that even if all goes well with UN negotiations, no global deal to bring down emissions will come into force until at least 2020. Our great-great-grandchildren will be cursing our delay.
