Decluttering before the New Year

Time off work during the holidays is a perfect time to tidy up your home and work spaces to start the New Year right.

STORY HIGHLIGHTS

• Do your New Year's resolutions include a push to clean up? Here are some tips to start


• Being organized is about being in control, says professional organizer Susan Fleischman


• Cleaning clutter can eliminate the need to buy what you simply can't find

(CNN) -- Whatever other resolutions we make leading up to the New Year -- to call Mom more often, lay off the late-night snacks -- getting ourselves organized is likely near the top of the list. And that often means clearing out the clutter that keeps us from functioning efficiently, whether we're at work or at home.

Many employees -- whether they go to actual offices or do their jobs from home -- find the last week of the calendar year is ideal for sorting through e-mails, clearing their desks, and reorganizing their work spaces. Sorting through stuff is rarely fun, but those who tackle it now will find themselves a step ahead when their now-vacationing colleagues and clients come staggering back after the holidays.

According to the National Association of Professional Organizers, which sponsors the annual "Get Organized Month" each January to help folks take control of their time, tasks and possessions, 83% of members polled say that "paper organization" ranks highest on their individual and corporate clients' to-do lists. For people taking time off between Christmas and New Year's, this week offers a chance to get things in order before 2013 arrives.

Devoting time to both physically and mentally clearing out the "old" and embracing the "new" is about more than just getting rid of stuff. Being organized is really about being in control, says Susan Fleischman, a Chicago-based professional organizer, home stager and founder of clutterfree.

"As joyous as the holidays can be, the period between Thanksgiving and New Year's is probably one of the most stressful of the year for people," she says. That's why spending the week after Christmas decluttering "really helps you recover and detox from the hustle and bustle of the holidays.

"It's very symbolic -- we're ramping up to the ultimate do-over. We all get to turn the calendar page and make a fresh start."

For those at work, says Fleischman, "the phone stops ringing, there are fewer meetings. Real work probably comes to a screeching halt. There are far fewer reasons to keep letting getting organized fall to the bottom of the to-do list." And these days, when employees often feel compelled to work harder and longer, being organized can be a real competitive advantage.

NAPO Industry Member Director Mary Dykstra says that on average, Americans waste time amounting to between six and 12 weeks a year searching for things in their offices and homes. "Just imagine if you could get out from under that clutter and spend that time helping your company build their business and ultimately, your career," says Fleischman, who was a public relations and marketing executive before launching her professional organizing business.

"Every minute counts when it comes to impressing the boss, your colleagues and clients. At work, we strive to project that we're knowledgeable, in control and experts. We're constantly accessing, sharing, reacting to information. Being able to put your hands on the information or generate some information means the better you'll be able to rise to the top and have clarity of thought and creativity, and maximize productivity."

But what about moving from work to the home front? Cynthia Ewer, the Washington state-based editor of OrganizedHome.com and the author of "The Complete Idiot's Guide to Getting Organized Fast-Track," suggests we use this in-between-holidays week to step back and reflect on our habits and how well they're working for us at home.

It's important to remember, says Ewer, that "there are different personality types. "Organized" is what works for you. There are filers -- people who love folders. They want the serenity of knowing where things are. Pilers like to keep their eyes on their stuff. Deniers have bags of paperwork shoved into closets. Instead of using a "What-does-it-look-like?" yardstick, it's a "How-will-it-work?" question. Know yourself, and come up with solutions that reflect who you are, she says.

After all, she says, " 'It's here somewhere' is the most frustrating phrase in the English language."

Cutting clutter also can boost the bottom line. "How many times do you go to the store and buy the things you couldn't find?" asks Fleischman. But cleaning up and cleaning out also can generate money, says Ewer.

"It can be a real fun process to turn your clutter into cash."

Nab tax deductions by donating cleared-out items to nonprofit organizations. Declutterers can send usable books, DVDs, video games, and music to third-party merchants in exchange for gift cards through the Amazon Trade-In Program. Even computer manufacturers like Apple offer gift cards to customers who send in an old iPhone, iPad, or computer for reuse or recycling if those devices still have monetary value.

"Leading an orderly life is about saving time, saving money, reducing stress," says Fleischman, who also blogs about organizing tips and clutter makeovers. "And that's energy you can spend on leisure pursuits, which is very important to emotional well-being."

Some tips for cutting through the workplace and home clutter this holiday week:

• Stockpile your supplies. Fleischman advises making sure you've got the right trash bins, shredders, file folders and markers at your fingertips before you start sorting and tossing.
• Take it a zone at a time. Your office, home and car didn't become a mess overnight, so declutter in increments. Fleischman suggests starting with desktops, then floors, then moving on to file cabinets and bookcases.
• Go from horizontal to vertical piles. If you're purging papers, clear those piles from your desk and the floor by placing newly sorted files in a cabinet or an upright vertical file. This way, your eyes can quickly scan and identify what you need at a glance.
• Free up the fridge. "Get the ghosts of Christmas past out of there -- all those little cans of this and that, the beef sticks from the gift basket no one can bear to throw out," says Ewer. Besides, this clean-up also will save you some calories.
• Be realistic. If you really write out bills at the kitchen table and not in the home office, says Ewer, get yourself a wheeled cart you can roll where the work gets done. If your kids' toys actually live in the family room -- not in the bedroom toy box -- create a storage solution there.

"Look at your patterns of living and organize yourself accordingly."

Study: Cancer drug substitute linked to higher rate of relapse

(CBS News) Abby Alonzo was 10 when she was diagnosed in 2009 with Hodgkin's lymphoma, a cancer of the immune system. With proper treatment, 90 percent of patients survive.

"It wasn't as hard for me as I think it as it was on my mom and my brother and my dad," Abby says.

Abby began a seven-drug regimen. But in 2010, doctors told Abby's mother, Katie, there was a nationwide shortage of one of the medicines -- mechlorethamine.

"I started to get a little hysterical, 'Why is it not available?'" says Katie.

In 2010, 23 cancer drugs had shortages. Reasons include manufacturing problems and low profit margins for the drugs, which became mostly generic, and therefore less expensive, than brand-name.

"There is really nothing you can do," Katie says. "You do what your doctor tells you to do, you take what medications your doctor tells you to take, and you pray that it works. And if one of those medications isn't available, you just take, you know, the next-best thing."

Doctors thought the next-best thing for patients like Abby was a drug called cyclophosphamide.

Life-saving cancer drugs for children stuck in federal legislative limbo

But a new study in the New England Journal of Medicine showed 88 percent treated with the original drug were cancer-free after two years -- compared to only 75 percent of those receiving the replacement drug.

"This is the first study to clearly show that when we substitute one drug for what we think is just an equally good drug, that's not always going to be the case. So it's demonstrating a negative impact on patients," says Dr. Richard Gilbertson, the director of cancer care at St. Jude Children's Research Hospital.

Abby was one of the patients who relapsed. She then needed a bone marrow transplant, radiation and more chemotherapy. Right now, she shows no signs of cancer.

"What if I relapsed again? Or what if something else happens? You know, it is just really scary, that part," Abby says.

The original drug in the study is finally available again after almost three years. But there are still 13 drugs used in cancer therapy, and a total of 100 on the FDA shortage list.

Congress passed legislation last July giving the FDA more authority to deal with cancer drug shortages. That new law has made a big difference, and the key provision is the requirement that drug manufacturers let the FDA know when there's an impending shortage.

Since that law was passed, there has been a doubling of those notifications, so the FDA can increase imports from abroad and tell other manufacturers in the United States to step up production.

Another provision in that law is that the FDA set up a task force looking at other possible solutions to the drug shortage crisis, and they're required to submit that report to Congress by this coming July.

WH Lashes Out at 'Congressional Stupidity'

With only days to come up with a deal to avoid the fiscal cliff, the White House said “congressional stupidity” was damaging the economy but that an agreement could be reached if Republican leaders don’t get in the way.

President Obama cut his Hawaiian vacation short and headed back to Washington today while the Senate is scheduled to reconvene on Thursday. House Speaker John Boehner, R-Ohio, said previously that he would give House members a 48-hour notice of any upcoming vote, which means that the soonest the House could consider a bill would be Saturday — just two days before a deadline to make a deal or trigger a rise in taxes and steep budget cuts.

Boehner and other GOP leaders issued a statement today following a conference call saying: “The House has acted on two bills which collectively would avert the entire fiscal cliff if enacted. Those bills await action by the Senate.  If the Senate will not approve and send them to the president to be signed into law in their current form, they must be amended and returned to the House.”

While Boehner put the onus on the president and Senate Majority Leader Harry Reid, a White House official used testy language to  put the responsibility back on Boehner and Senate Minority Leader Mitch McConnell.

“What we need is for the Senate Minority Leader not to block a vote and for Boehner to allow a vote,” a White House official told ABC News. “The hits to our economy aren’t coming from outside factors, they’re coming from congressional stupidity.”

Reid’s plan would serve as a Democratic counterpart to Boehner’s plan B, which failed to gain enough support for a vote last week. Boehner left the ball in the Senate’s court after withdrawing  his plan Thursday.

Any plan from Reid is expected to include extending the Bush tax cuts for Americans making $250,000 or less.

Related: What if Bush tax cuts expire?

This has been a sticking point for the left and the right throughout discussions. Democrats believe that lower- and middle-class families should keep the  tax cut, while letting it expire for households making more than $250,000. Republicans counter that no Americans should be forced to pay higher taxes come Jan. 1, though Boehner’s plan would have required those making more than $1 million to lose the cut.

Reid could also propose cuts to tax deductions to generate more federal revenue.

Related: Can the mortgage deduction survive the fiscal cliff?

Michael Ettlinger, vice president for economic policy at the liberal think tank Center for American Progress, said that would make his plan very similar to Obama’s.

“I think this is likely to go smaller more than bigger as they try to gather votes in the Senate,” Ettlinger told ABC News Wednesday. “The Democratic vision of things is fairly clear. Where the Senate Republicans are willing to go is less so. That’s going to be the issue.”

Dan Holler of conservative policy advocacy group Heritage Action for America expects the plan to include an extension of unemployment benefits, something he says would be “extremely counterproductive for the economy.”

Democrats “see it as one of the most stimulative things you can do,” Holler told ABC News Wednesday. “Heritage has great research to go ahead and say this doesn’t really help.”

Related: Fiscal Cliff negotiators search for cuts without sacrifice.

In addition to an immediate measure to stop taxes from going up, Holler suggested there would be a mechanism to compel leaders to do more further down the road, a method he said has not historically been effective at reducing the deficit.

“I think Republicans are going to look at the entire package skeptically,” Holler said of Reid’s expected plan.

Boehner press secretary Michael Steel told ABC News the speaker’s office “will take a look” at Reid’s proposal once he brings it up for a vote or shares his ideas with the House.

Garnering consensus among both parties will be difficult for any plan now. Starbucks CEO Howard Schultz is trying to bring D.C. politicians together with every coffee cup sold in the District.

Critics have called into question  Boehner’s ability to bring his own party together.

“It seems that, in the House now, Boehner has no control over his extreme right-wing faction,” Sen. Bernie Sanders, I-Vt., said on MSNBC Wednesday. “You have, over in the House, a situation where the Republicans are saying, ‘Hey, we don’t think billionaires should pay a nickel more in taxes, but we do think there should be devastating cuts in programs that are impacting working families who are already hurting as a result of the recession.’ So that’s the problem that we have.”

THIS was the year we held our breath in almost unbearable anticipation while we waited to see whether physicists at the Large Hadron Collider would finally get a clear view of the Higgs boson, so tantalisingly hinted at last December. Going a bit blue, we held on through March when one of the LHC's detectors seemed to lose sight of the thing, before exhaling in a puff of almost-resolution in July, when researchers announced that the data added up to a fairly confident pretty-much-actual-discovery of the particle.

Early indications were that it might be a weird and wonderful variety of the Higgs, prompting a collective gasp of excitement. That was followed by a synchronised sigh of mild disappointment when later data implied that it was probably the most boring possible version after all, and not a strange entity pointing the way to new dimensions and the true nature of dark matter. Prepare yourself for another puff or two as the big story moves on next year.

This respirational rollercoaster might be running a bit too slowly to supply enough oxygen to the brain of a New Scientist reader, so we have taken care to provide more frequent oohs and aahs using less momentous revelations. See how many of the following unfundamental discoveries you can distinguish from the truth-free mimics that crowd parasitically around them.

1. Which of these anatomical incongruities of the animal kingdom did we describe on 14 July?

• a) A fish, found in a canal in Vietnam, that wears its genitals under its mouth
• b) A frog, found in a puddle in Peru, that has no spleen
• c) A lizard, found in a cave in Indonesia, that has four left feet
• d) A cat, found in a tree in northern England, that has eight extra teeth

2. "A sprout by any other name would taste as foul." So wrote William Shakespeare in his diary on 25 December 1598, setting off the centuries of slightly unjust ridicule experienced by this routinely over-cooked vegetable. But which forbiddingly named veg did we report on 7 July as having more health-giving power than the sprout, its active ingredient being trialled as a treatment for prostate cancer?

• a) Poison celery
• b) Murder beans
• c) Inconvenience potatoes
• d) Death carrots

3. Scientists often like to say they are opening a new window on things. Usually that is a metaphor, but on 10 November we reported on a more literal innovation in the fenestral realm. It was:

• a) A perspex peephole set in the nest of the fearsome Japanese giant hornet, to reveal its domestic habits
• b) A glass porthole implanted in the abdomen of a mouse, to reveal the process of tumour metastasis
• c) A crystal portal in the inner vessel of an experimental thorium reactor, to reveal its nuclear fires to the naked eye
• d) A small window high on the wall of a basement office in the Princeton physics department, to reveal a small patch of sky to postgraduate students who have not been outside for seven years

4. On 10 March we described a new material for violin strings, said to produce a brilliant and complex sound richer than that of catgut. What makes up these super strings?

• a) Mousegut
• b) Spider silk
• c) Braided carbon nanotubes
• d) An alloy of yttrium and ytterbium

5. While the peril of climate change looms inexorably larger, in this festive-for-some season we might take a minute to look on the bright side. On 17 March we reported on one benefit of global warming, which might make life better for some people for a while. It was:

• a) Receding Arctic sea ice will make it easier to lay undersea cables to boost internet speeds
• b) Increasing temperatures mean that Greenlanders can soon start making their own wine
• c) Rising sea levels could allow a string of new beach resorts to open in the impoverished country of Chad
• d) More acidic seawater will add a pleasant tang to the salt water taffy sweets made in Atlantic City

6. In Alaska's Glacier Bay national park, the brown bear in the photo (above, right) is doing something never before witnessed among bearkind, as we revealed on 10 March. Is it:

• a) Making a phonecall?
• b) Gnawing at a piece of whalebone to dislodge a rotten tooth?
• c) Scratching itself with a barnacle-covered stone tool?
• d) Cracking oysters on its jaw?

7. Men have much in common with fruit flies, as we revealed on 24 March. When the sexual advances of a male fruit fly are rejected, he may respond by:

• a) Whining
• b) Hitting the booze
• c) Jumping off a tall building
• d) Hovering around the choosy female long after all hope is lost

8. While great Higgsian things were happening at the LHC, scientists puzzled over a newly urgent question: what should we call the boson? Peter Higgs wasn't the only physicist to predict its existence, and some have suggested that the particle's name should also include those other theorists or perhaps reflect some other aspect of the particle. Which of the following is a real suggestion that we reported on 24 March?

Real growth in household incomes over past 5 years despite higher inflation: MOF

SINGAPORE: Singapore's economic growth slowed significantly this year, as subdued external demand affected most sectors of the economy.

But findings from the Ministry of Finance's second issue of the Singapore Public Sector Outcomes Review (SPOR) showed that there has been real growth in household incomes over the past five years despite higher inflation.

Median monthly household incomes dipped in 2009 to S$4,850 with the economic downturn, although these remain higher than five years ago - S$4,267 in 2005.

Incomes have since risen in 2010 with the economic recovery and tighter labour market.

The review found that to keep incomes on a sustainable growth path, the skills and productivity of workers must be raised. If the goal of raising productivity by two to three per cent per year over the next decade is achieved, median real incomes should grow by about 30 per cent over 10 years.

Published once every two years, SPOR provides a perspective on how the public sector and Singapore have fared in six broad range of areas of national interest including growing incomes and fostering strong families and a cohesive society.

The review said immediate challenges remain but are being addressed and these include relieving pressure in public housing and transport infrastructure.

Beyond these, SPOR said the government must keep sight of long-term issues vital to Singapore's survival, security and success.

Public policy will also have to take into account a greater diversity of needs and interests as society evolves.

The current Our Singapore Conversation is an effort to involve many Singaporeans in gathering aspirations and hopes for Singapore's future, and ideas on how we can achieve them together.

AR-15 gun sales continue to spike after shootings

(CBS News) The Newtown shootings and Monday's ambush in Webster, N.Y., have fueled the debate over gun control.

While that debate intensifies, something else is spiking: Gun sales.

At gun shows across the nation this past weekend people stood in line hoping to get their hands on an AR-15, the military-style rifle used in the Newtown Connecticut school shooting.

As NRA is criticized on shooting response, bullets sell

There's been a run on AR-15s at gun stores, too.

"I normally sell about 15-20 a month. I've sold about 30 in the last three days," said Rick Friedman, who owns RTSP in Randolph, N.J.

The reason, he says, is clear: "Because people want to make sure they can own them legally before they get the right taken away."

The White House said after the Newtown shooting that President Barack Obama supports a ban on assault weapons proposed by California Democratic Senator Diane Feinstein. Getting it through Congress quickly is highly unlikely, but the mere mention of a ban is enough to send sales soaring. And it's not just guns.

Brownells, the world's largest firearms supplier, says it recently sold more than three-and-a-half years worth of AR-15 magazines in three days.

Even before Newtown, sales of guns and ammunition this year were surging.

FBI background checks of potential gun buyers were up 31 percent in November 2012 over 2011.

Chuck Nesby, an instructor at Nova Firearms in Falls Church, Va., said they nearly sold out of AR-15s and high-capacity magazines after the shooting in Newtown.

CBS News

In a report issued prior to Newtown, the market research firm IbisWorld, which tracks the gun industry, found "Gun enthusiasts are working themselves into a frenzy over what another four years under the Obama administration may hold for gun laws."

Chuck Nesby is an instructor at Nova Firearms in Falls Church, Va., where they nearly sold out of AR-15s and high-capacity magazines after Newtown.

"If I could I would give Sen. Feinstein and the president salesmen of the year awards."

Sen. Feinstein plans to introduce her bill to ban the sale or manufacturer of assault weapons on the first day of the new Congress in January. That's expected to trigger yet another boost in gun sales.

Gunman Killed Firemen With Bushmaster, Left Note

A convicted killer, who shot dead two firefighters with a Bushmaster assault rifle after leading them into an ambush when they responded to a house fire he set in Western New York, left behind a typewritten note saying he wanted to "do what I like doing best, killing people," police said.

William Spengler, 62, set his home and a car on fire early Monday morning with the intention of setting a trap to kill firefighters and to see "how much of the neighborhood I can burn down," according to the note he wrote and which police found at the scene. The note did not give a reason for his actions.

Spengler, who served 18 years in prison for beating his 92-year-old grandmother to death with a hammer in 1981, hid Monday morning in a small ditch beside a tree overlooking the sleepy lakeside street in Webster, N.Y., where he lived with his sister, police said today in a news conference.

Police said they found remains in the house, believed to be that of the sister, Cheryl Spengler, 67.

As firefighters arrived on the scene after a 5:30 a.m. 911 call on the morning of Christmas Eve, Spengler opened fire on them with the Bushmaster, the same semi-automatic, military-style weapon used in the Dec. 14 rampage killing of 20 children in Newtown, Conn.

"This was a clear ambush on first responders… Spengler had armed himself heavily and taken area of cover," said Gerald Pickering, the chief of the Webster Police Department.

Armed with a Smith & Wesson .38 caliber revolver, a Mossman 12-gauge shotgun, and the Bushmaster, Spengler killed two firefighters, and injured two more as well as an off-duty police officer at the scene.

As a convicted felon, Spengler could not legally own a firearm and police are investigating how he obtained the weapons.

One firefighter tried to take cover in his fire engine and was killed with a gunshot through the windshield, Pickering said.

Responding police engaged in a gunfight with Spengler, who ultimately died, likely by a self-inflicted gunshot wound to the head.

As police engaged the gunman, more houses along Lake Ontario were engulfed, ultimately razing seven of them. Some 33 people in adjoining homes were displaced by the fire.

SWAT teams were forced to evacuate residents using armored vehicles.

Police identified the two slain firefighter as Lt. Michael Chiapperini, a 20-year veteran of the Webster Police Department and "lifetime firefighter," according to Pickering, and Tomasz Kaczowka, who also worked as a 911 dispatcher.

Two other firefighters were wounded and remain the intensive care unit at Strong Memorial Hospital in Rochester, N.Y.

Joseph Hofsetter was shot once. He sustained an injury to his pelvis and has "a long road to recovery," said Dr. Nicole A. Stassen, a trauma physician.

The second firefighter, Theodore Scardino, was shot twice and received injuries to his left shoulder and left lung, as well as a knee.
