5 Concerns For Small Businesses In 2013

NEW YORK ? In 2013, small business owners will contend with many of the same issues that made it hard to run their companies over the last 12 months.

They're also heading into the new year with a lot of uncertainty. It's unlikely that negotiations in Congress will resolve all of lawmakers' disagreements over tax and budget issues that affect small businesses. And there are still many questions about the implications of the health care law for small companies.

That points to continued caution ? and perhaps slow hiring ? among the nation's small companies.

"Uncertainty is the bane of every small business," says Scott Shane, a professor of entrepreneurship at Case Western Reserve University's Weatherhead School of Management in Cleveland. "Their only rational response is to pull in their horns and slow down."

Small businesses aren't likely to get much encouragement from the economy. It's expected to grow by no more than 3 percent in 2013, according to the Federal Reserve. That's a moderate pace, better than the 1.7 percent that the economy grew during the first three quarters of 2012. But it's also far from robust.

Here's a look at some of the issues facing small businesses in the coming year:

TAXES

Lawmakers are still haggling over what's called the fiscal cliff, the combination of billions of dollars in tax increases and budget cuts. Even if Congress reaches an agreement, small business owners won't have the certainty they need, according to Todd McCracken, president of the National Small Business Association, a group that lobbies on behalf of small companies.

"It almost surely won't be comprehensive enough that we won't be revisiting it next year," McCracken says. He's concerned that there'll be another fiscal cliff in six months ? which would mean more negotiations and more uncertainty.

Many small business owners are worried about their personal tax rates. Sole proprietors, partners and owners of what are called S corporations, all report the income from their businesses on their individual Form 1040 returns. That means their companies are in effect taxed at personal rates, which can be higher than corporate rates.

One of the most important tax provisions for small businesses, what's known as the Section 179 deduction, will shrink to $25,000 next year from $125,000 in 2012. The deduction, which applies to equipment purchases, was $500,000 in 2011. Congress can increase the deduction at any time, even after 2013 has begun. But for the time being, business owners can't count on getting a big break.

"It's a huge change for companies planning on making investments," McCracken says.

It's not known if Congress will extend the 2 percentage point payroll tax cut that workers have had for two years. If it doesn't, consumers will have less money in their paychecks to spend, and that is likely to affect retailers and any other small businesses that sell directly to the public.

HEALTH CARE

Health care has been another source of uncertainty for small business owners. The new year will bring some, but probably not all, of the answers to questions about how the new health care law will affect them. Many will have to devote some time to understanding the law ? or hire someone to help them do it.

"They'll have to get their arms around the law, look at their options, learn more about the exchanges," says John Arensmeyer, CEO of Small Business Majority, a lobbying group.

Under the law, companies with 50 or more employees will be required to provide affordable health care insurance for their employees starting Jan. 1, 2014. During 2013, federal and state health insurance exchanges will be set up, and owners will be able to see how much it will cost them to buy insurance. As the year begins, however, many small business owners don't know whether their states will be creating exchanges, or whether they'll have to go into the national system ? and they don't know what that will mean for their costs.

For some owners, that information will help them decide whether they will buy insurance, or whether they'll decide it's cheaper to not provide coverage and just pay the government a $2,000-per-employee fine. For those who have close to 50 workers, they may decide to not hire more workers in order to remain outside the law's jurisdiction.

LENDING

Don't look for the small business lending climate to get easier in 2013. Owners who are uneasy about the economy, taxes and health care aren't expected to significantly increase their borrowing, especially as many have been paying down debt since the recession. But even those who are ready to borrow are expected to find it's still hard to get a loan. Bankers are unlikely to be more liberal in their lending policies.

Depressed lending levels may be with us well beyond 2013, says James Schrager, a professor of entrepreneurship at the University of Chicago Booth School of Business.

The problem isn't just that banks are cautious about small business loans. Schrager notes that home equity loans, a traditional source of money for people starting or expanding a business, remain difficult to get, the result of the collapse in the mortgage market in 2008.

Small Business Majority's Arensmeyer is hopeful that a bill introduced in Congress this year to allow credit unions to make more loans to small businesses will get more traction when the new Congress convenes. That bill would more than double the amount of total assets that credit unions can use to lend to small businesses to 27.5 percent.

But he's also not expecting major changes in lending next year.

"Sadly, I don't think we're going to increase our access to capital overnight," he says.

ONSHORING

A trend that's expected to gain speed in 2013 is what's calling onshoring. That's the term for manufacturing that had been done overseas, and that's now taking place back in U.S. factories. Apple Inc. earlier this month said it would move production of some of its Mac computers to the U.S. from China next year ? but many small businesses have already been making the switch. While Apple is an example of a big company moving in this direction, the majority of U.S. manufacturers are small businesses.

There are several reasons behind the trend. As China becomes more of a middle-class country, wages for its workers are rising, and that is lessening some of the appeal of manufacturing there for U.S. companies, says Steven Kaplan, a professor of entrepreneurship and finance at Chicago's Booth School. Over the past two decades, it was the cheaper labor in China that prompted businesses of all sizes to have everything from computers to clothes to food ingredients made in China.

The rising cost of fuel, which has made transporting goods more expensive, is another factor in onshoring.

"Manufacturing in the U.S. is relatively more attractive than it has been in 20 years," Kaplan says.

SKILLED WORKER SHORTAGE

While companies' caution has weighed on the job market, many company owners who actually want to hire say it's hard to find workers to fill some positions.

It's becoming more difficult to find people who have the skills they need, these owners say. Many new manufacturing jobs require high-tech skills. They include positions at factories where computers are used to create products like airplane parts and machinery. And some require several years of training, says Shane, the Case Western Reserve professor. For example: A company that makes metal molds which are in turn used to create automobile dashboards. That takes a machinist who knows cutting-edge processes to make the molds.

"You cannot take someone off the street to do it," Shane says.

Because of changing technology, owners are struggling to find qualified workers in 2013.

"There's a whole level of work that's going to require skills that weren't needed in traditional jobs," says Arensmeyer. He notes that community colleges around the country are offering courses that will help train workers to fill these jobs. But training takes time, and the demand for jobs may continue to outstrip the supply of qualified workers.

Elizabeth Gregory: Aging Sperm? Not the World's End

Judith Shulevitz's recent New Republic essay on how later parenthood is "upending American society" claims that delaying kids could lead us down a rabbit hole of genetic decline. The piece gathers much of its energy from new studies suggesting that male sperm quality decays with age.

While female infertility is old news, issues with male fertility create a new cultural frisson. Apparently, genetic errors may be introduced into sperm every time they divide -- which is often. So the children of some older men may have issues, cognitive and physical, that the kids of younger men don't generally face (at least not due to their dad's contribution to their DNA).

There's a lot of emphasis on the word "may" in the New Republic piece, since most of the evidence it's based on is inconclusive. And there's a strong element of anecdote as well. Fertility catastrophizing is an ongoing sport. Here are some links to other fertility scaremongering pieces of the past few years that turned out to be not the big problems the headlines suggested: the ovarian reserve scare, the later-parenthood autism scare, and the childlessness scare. Earlier this month we had the low-birth-rate scare (which turns out to really be about young women delaying kids in order to establish themselves -- a time-lag effect).

In the case of new dads over 50, several studies do suggest that their kids may have a higher rate of schizophrenia (about 1 percent) than those of younger dads (about 0.25 percent), and there may be links to other ailments. Time, and more completed studies, will tell. The same is true of studies of the effects of fertility treatments like Clomid on both kids and moms, which the essay also raises as potentially devolutionary. The data is still in the gathering stages.

As there has been all along, there's reason to ask women and their doctors to think through their fertility options before turning to fertility tech and drugs. Firm data on rates of pregnancy in the late 30s and early 40s is scarce, because doctors can't mandate that a big group of people have unprotected sex constantly for the sake of an experiment. But one study indicates that most women not already known to have an endocrinal disorder or blockage will get pregnant without aid in their late 30s within two years. Many find two years too long a wait before seeking fertility boosters -- and certainly it's reasonable for women to get their hardware checked out early on in their fertility efforts, or even before they're ready to start trying for kids. But of the 580,000 kids born to women 35 and over in 2010, only 5 percent involved IVF (per CDC and SART 2010 data). We can't track how many involved Clomid or IUI. For more on rates of decline, click here.

Fertility treatments should be more regulated and tracked than they are. We know little about the long-term effects of the treatments we're using on a wide scale. But it's my opinion the presentation of data in this essay is questionable. Potential problems should be noted and discussed, but there's no basis for jumping to end-of-the-world conclusions. We are not falling off a fertility cliff.

Looking at the same question from the positive side, at least such hand wringing does open up discussion of these issues. Suggestions of declining quality of sperm among later dads shares out some of the weight that's been jammed on the shoulders of later moms in our fertility discourse.

Different from older moms' situation, however, these male fertility issues are addressable with relative ease. For women, IVF and egg donation involve injections of high doses of hormones with unknown long-term effects, huge expense for each attempt, and ethical questions over the use of poorer women's genetic material for the benefit of richer couples.

By comparison, for men worried about potential issues with their aging reproductive materials, arranging for sperm donation is a breeze. The cost is negligible, and no risky hormone injections are required. If you want familial DNA connections, there's the real option for many of using a nephew's sperm -- or that of a younger brother. Or, if you don't have such a handy relative, or it's not a real option given your family dynamic but you do hope to propagate your own DNA, you can push for further research around generation of new sperm cells from an individual's adult stem cells, skin cells or other tissue. If perfected, such advances could allow men (and, interestingly, women too!) to generate new sperm cells bearing their DNA. These would be free of the genetic errors that older sperm have, because they haven't divided as often. Some animal experiments along these lines have been successful.

The understanding that spermatic dynamism fades with time may surprise us for a few minutes. But viewed in wider context, it's not the end of the world, guys. Modern fertility is changing at lightning speed, and along with it the stratification of tasks based on gender. Many of our old-world assumptions are being upended. But for women, men, families, and society, the new options introduced by control of fertility are largely positive and open the way to ongoing positive cultural evolution.

Dangers of Obesity Heart Liver Disease High Blood Pressure ...

Certified Medical Exercise Therapist, Weight Loss Specialist

www.EvansvilleWeightLoss.com

Through the dangers of heart disease, high blood pressure, liver disease, and other related diseases, obesity is killing almost 1,000 Americans every day. That?s over 300,000 people who could have lived longer, more healthful lives. Simply put, the dangers of obesity to your health and happiness cannot be overstated. Obesity is killing you!

Definition of Obesity

The medical community considers total body fat when determining obesity. By comparing one?s height and weight to the standardized Body Mass Index (BMI), health care professionals can determine whether or not you are obese. Obesity is from 30% BMI to 39.9% BMI. Morbid obesity begins at a BMI of 40%. That?s a weight of about 235 for a person who is 5?4? tall and a weight of about 280 for a person 5?10? tall.

Dangers of Obesity

While these figures may seem like some arbitrary standard, there are some very real dangers of obesity. Some of the illnesses and dangers of obesity are the following:

Heart Disease
More technically known as coronary heart disease (CHD), this illness is the leading cause of death in the United States. In CHD, fatty materials build up on the walls of the arteries causing blockages and elevated blood pressure thus placing undue strain on the heart. The dangers of heart disease ultimately result in a heart attack and, in many cases, death.

Diabetes
An imbalance in one of the regulatory systems in the body, diabetes is a disease that affects over 20 million Americans. Many factors, most notably obesity, often lead to diabetes. People afflicted with the disease must make fundamental changes in their eating habits, day to day activities and can be dependent on insulin.

Liver Disease
Liver disease
is a collection of conditions, disorders, and infections that affect the cells, structures, and tissues of the liver, causing liver damage or stops liver functioning altogether. Alcohol is often blamed but obesity can also lead to non-alcohol fatty liver, a deadly disease through the accumulation of triglycerides and cholesterol. The proper functioning of the liver is vital to almost every other process in the body and liver disease has a profound effect on one?s ability to lead a normal life.

Stroke
The lack of sufficient blood flow to the brain can lead to a cerebrovascular accident (CVA) or ?stroke.? Similar to the blockages formed in CHD, plaque builds up on the inside of the arteries feeding the brain thus causing an interruption in the necessary nutrients. Life changes immediately for stroke victims. Some form of physical disability affects 75% of those who have suffered from a stroke.

The Bottom Line

Obesity is a real problem with real ramifications. Obese people suffer from more physical and mental health problems than their thinner counterparts and enjoy a significantly reduced quality of life.

Losing weight need not be difficult, time consuming nor painful. The Advanced Anti-Aging and Weight Loss Clinic utilizes state of the art techniques and technology to help you lose weight quickly and safely. Not only can the friendly medical professionals help you achieve a healthier and happier life, you will also look better and feel better!?

Study hints that stem cells prepare for maturity much earlier than anticipated

Dec. 27, 2012 ? Unlike less versatile muscle or nerve cells, embryonic stem cells are by definition equipped to assume any cellular role. Scientists call this flexibility "pluripotency," meaning that as an organism develops, stem cells must be ready at a moment's notice to activate highly diverse gene expression programs used to turn them into blood, brain, or kidney cells.

Scientists from the lab of Stowers Investigator Ali Shilatifard, Ph.D., report in the December 27, 2012 online issue of Cell that one way cells stay so plastic is by stationing a protein called Ell3 at stretches of DNA known as "enhancers" required to activate a neighboring gene. Their findings suggest that Ell3 parked at the enhancer of a developmentally regulated gene, even one that is silent, primes it for future expression. This finding is significant as many of these same genes are abnormally switched on in cancer.

"We now know that some enhancer misregulation is involved in the pathogenesis of solid and hematological malignances," says Shilatifard. "But a problem in the field has been how to identify inactive or poised enhancer elements. Our discovery that Ell3 interacts with enhancers in ES cells gives us a hand-hold to identify and to study them."

In 2000, Shilatifard identified Ell3 as the third member of the Ell (for "Eleven-nineteen lysine-rich leukemia gene") family of elongation factors, proteins that increase the rate at which genes are expressed. "At the time, we didn't think much of Ell3 because it was highly expressed in testes," says Shilatifard, noting that then people thought that sperm were merely vessels used to carry paternal DNA to an egg and that associated factors would have little relevance to the regulation of future gene expression in the resulting embryo.

But a few years back, a curious Open University graduate student working in the Shilatifard lab, Chengqi Lin, started exploring a potential function for the neglected gene by initiating a global search for regions occupied by Ell3 in the genome of mouse embryonic stem cells. His search in collaboration with a bioinformatician in the Shilatifard lab, Alexander S. Garruss, revealed that Ell3 sits on more than 5,000 enhancers, including many that regulate genes governing stem cell maturation into spinal cord, kidney, and blood cells.

"What was interesting was that Ell3 marked enhancers that are active and inactive, as well as enhancers that are known as "poised," says Lin, referring to a transition state from inactive to active. "That indicated that Ell3's major function might be to prime activation of genes that are just about to be expressed during development."

The fact that silent genes can be "primed" for expression was no surprise: researchers knew that the enzymatic machine that copies DNA into the RNA blueprint for proteins -- a protein called Pol II -- often pauses at the start of a gene, presumably revving its engine in preparation to jump across the genetic start gate in response to a developmental signal. However, Shilatifard and colleagues showed several years ago that paused Pol II is not a prerequisite for rapid transcriptional induction.

The surprise came when researchers used a molecular trick to deplete mouse ES cells of Ell3 and then did a "genomic" survey. They found that paused Pol II vanished from the start sites of many genes in Ell3-deficient cells. This means that not only does Ell3 preferentially mark stem enhancers, but also that its presence there is necessary to keep an idling Pol II ready for action.

Most of the current study defines how, when the developmental time is right, enhancer-bound Ell3 cooperates with components of a big-boss elongation factor called the Super Elongation Complex to release Pol II from the start gate, allowing the expression of genes required for stem cell differentiation. Critical among those findings is their observation that mouse stem cells depleted of Ell3 failed to activate genes expressed in mature cell types.

These results alone are cause for any lab to start chilling the champagne, yet a surprising coda to the study, leaves readers with yet another revelation. Collaborating with Fengli Guo, Ph.D., head of the Stowers electron microscopy core, the team prepared highly magnified images of mouse sperm and observed that both Ell3 and Pol II were present, in sperm nuclei.

In mammals, gene expression regulated by Pol II, a process known as transcription, does not begin until the formation of a single-celled zygote, that is, well after the union of sperm and egg germ cells. "It is very significant that Ell3 and other factors that regulate transcription are found in sperm," says Lin, the study's first author. Lin is cautious in interpreting this finding, "but it would be very exciting to further investigate whether transcription factors found in sperm could contribute to the decondensation of sperm chromatin or even further gene activation after fertilization by serving as epigenetic markers."

Shilatifard is also cautious as questions remain to be explored, among them whether Ell3 and Pol II actually contact DNA inside sperm or whether similar processes occur in unfertilized eggs and function in this process. Nonetheless, he feels this finding has fundamental implications, not only for development, but also for where he's going next.

"This work has opened up a whole new area of research in my lab," says Shilatifard, who has in the last decade focused on aberrant gene expression associated with leukemia. "If we find that transcription factors bind to specific regions of chromatin in germ cells, I may focus on germ cells in the next few decades. This would open a huge door enabling us to determine the role of these factors in early development."

Zhuojuan Luo, Ph.D., a postdoctoral fellow in the Shilatifard lab, also contributed to the study.

Funding for the study came from the Stowers Institute for Medical Research, the National Institutes of Health (Shilatifard R01CA89455 and R01CA150265), and Alex's Lemonade Stand Foundation.

2012 has seen an acknowledgement and mainstream awareness of the challenges of managing the burgeoning streams of information generated and available to organizations, particularly big data. In 2013, I expect the focus to shift to the challenges of developing and implementing enterprise strategies for making use of all this data.

Opportunities abound for deploying information in transformative ways. Gartner?s 2013 research agenda will help IT and business leaders develop and execute strategies for achieving higher returns on their information assets. This includes leveraging big data, enhancing analytic capabilities, achieving more disciplined information asset management approaches, and incorporating new and expanded information-related roles:

The volume, velocity, and variety of information sources available today to organizations is more than just an information management challenge. Rather this phenomenon represents an incredible opportunity to improve enterprise performance significantly and even transform their businesses or industries. More than merely reporting on information or even basic decision making support, information assets are an instrument for innovation. Making this strategic shift quickly enough to meet create competitive advantage is the real challenge for most businesses.

Key issues Gartner will be exploring throughout the coming year are also questions business and IT leaders should be asking themselves:

Business uses and sources of information

  • What are the range of internal and external sources of data available, starting with our own underutilized ?dark data??
  • How can information be used, not just for decision-making, but for greater business insights and process automation?
  • How can information be used to foster relationships and improve collaboration with our employees, partners, customers and/or suppliers?
  • How can information facilitate business transformation and innovation, beyond just incremental performance improvements?
  • How can information be monetized by packaging, sharing and/or selling it?

Information leadership

  • How can we evolve to a more information-centric culture?
  • How can our IT and business groups organize for achieving higher levels of information performance?
  • What emerging information-related skills and methods should be considered, planned for, used or acquired?

Big Data

Value and economics of information (infonomics)

  • Why should and how can we inventory, measure and quantify their information assets?
  • How can information?s value be used to justifying and gauge the?ROI of information-related initiatives, as well as other IT and business initiatives?
  • How can businesses manage information as an actual corporate asset?

So if you?re looking to make a corporate New Year?s resolution to do more with data for driving corporate value, consider developing answers to each of these questions. And keep an eye on Gartner?s Information Innovation research throughout 2013.

Hugo Chavez Health Update: Venezuela President Up, Walking, VP Says, But Doubts Persist

CARACAS, Venezuela -- Vice President Nicolas Maduro surprised Venezuelans with a Christmas Eve announcement that President Hugo Chavez is up and walking two weeks after cancer surgery in Cuba, but the news did little to ease uncertainty surrounding the leader's condition.

Sounding giddy, Maduro told state television Venezolana de Television that he had spoken by phone with Chavez for 20 minutes Monday night. It was the first time a top Venezuelan government official had confirmed talking personally with Chavez since the Dec. 11 operation, his fourth cancer surgery since 2011.

"He was in a good mood," Maduro said. "He was walking, he was exercising."

Chavez supporters reacted with relief, but the statement inspired more questions, given the sparse information the Venezuelan government has provided so far about the president's cancer. Chavez has kept secret various details about his illness, including the precise location of the tumors and the type of cancer. His long-term prognosis remains a mystery.

Dr. Michael Pishvaian, an oncologist at Georgetown University's Lombardi Cancer Center in Washington, said it was an encouraging sign that Chavez was walking, and it indicated he would be able to return to Venezuela relatively soon. But he said the long term outlook remained poor.

"It's definitely good news. It means that he is on the road to recover fully from the surgery," Pishvaian said in a telephone interview with The Associated Press. "The overall prognosis is still pretty poor. He likely has a terminal diagnosis with his cancer that has come back."

Pishvaian and other outside doctors have said that given the details Chavez has provided about his cancer, it is most likely a soft-tissue sarcoma.

Chavez first underwent surgery for an unspecified type of pelvic cancer in Cuba in June 2011 and went back this month after tests had found a return of malignant cells in the same area where tumors were previously removed.

Venezuelan officials said that, following the six-hour surgery two weeks ago, Chavez suffered internal bleeding that was stanched and a respiratory infection that was being treated.

Maduro's announcement came just hours after Information Minister Ernesto Villegas read a statement saying Chavez was showing "a slight improvement with a progressive trend."

Dr. Carlos Castro, director of the Colombian League against Cancer, an association that promotes cancer prevention, treatment and education, said Maduro's announcement was too vague to paint a clear picture of Chavez's condition.

"It's possible (that he is walking) because everything is possible," Castro told AP. "They probably had him sit in up in bed and take two steps."

"It's unclear what they mean by exercise. Was it four little steps?" he added. "I think he is still in critical condition."

Maduro's near-midnight announcement came just as Venezuelan families were gathering for traditional late Christmas Eve dinners and setting off the usual deafening fireworks that accompany the festivities. There was still little outward reaction on a quiet Christmas morning.

Danny Moreno, a software technician watching her 2-year-old son try out his new tricycle, was among the few people at a Caracas plaza who said she had heard Maduro's announcement. She said she saw a government Twitter message saying an announcement was coming and her mother rushed to turn on the TV.

"We all said, thank God, he's okay," she said, smiling.

Dr. Gustavo Medrano, a lung specialist at the Centro Medico hospital in Caracas, said if Chavez is talking, it suggests he is breathing on his own despite the respiratory infection and is not in intensive care. But Medrano said he remained skeptical about Maduro's comments and could deduce little from them about Chavez's prognosis for recovery.

"I have no idea because if it was such a serious, urgent, important operation, and that was 14 days ago, I don't think he could be walking and exercising after a surgery like that," Medrano said.

Over the weekend, Chavez's ally, Bolivian President Evo Morales, made a lightning visit to Cuba that only added to the uncertainty.

Journalists had been summoned to cover his arrival and departure in Havana, but hours later that invitation was canceled. No explanation was given, though it could have been due to confusion over Morales' itinerary as he apparently arrived later than initially scheduled.

Cuban state media published photos of President Raul Castro receiving Morales at the airport and said he came "to express his support" for Chavez, his close ally, but did not give further details. He left Sunday without making any public comments.

For the second day in a row Tuesday, Morales made no mention of his trip to Cuba during public events in Bolivia.

Yet more questions surround Chavez's political future, with the surgery coming two months after he won re-election to a six-year term.

If he is unable to continue in office, the Venezuelan Constitution calls for new elections to be held. Chavez has asked his followers to back Maduro, his hand-picked successor, in that event.

Venezuelan officials have said Chavez might not return in time for his Jan. 10 inauguration.

Opposition leaders have argued that the constitution does not allow the president's swearing-in to be postponed, and say new elections should be called if Chavez is unable to take the oath on time.

But government officials have said the constitution lets the Supreme Court administer the oath of office at any time if the National Assembly is unable to do it Jan. 10 as scheduled.
