Why do some handle stress better than others


For some students, just going to school can be very stressful.? Add standardized tests to the mix, and even a gifted student can be unnerved.? ?

Performing well on high school competency exams opens the door to a student?s academic future like never before.? In some cases, the pressure has even filtered down to elementary school?where competition for collegiate scholarships has found a surprising new starting place.

In this Just Explain It, we?ll break down the science behind why some students perform well under pressure, while others don?t.? We?ll also look into what can be done to help students perform better in stressful situations.

Researchers have found that the success of some students can be linked to how fast dopamine is cleared from their brain.

Dopamine is a chemical messenger that helps transmit signals between nerve cells of the brain.? The chemical has many functions, playing important roles in behavior and cognition, attention, working memory and learning. Our brains work best when there?s not too much or too little dopamine.

That?s where what?s known as the COMT gene comes into play - and it comes in the form of two variants. The fast variant removes dopamine quickly and the slow variant removes the chemical gradually.

Studies of people in two environments were conducted?one under normal conditions, the other under stressful conditions.? It was found that under normal conditions, people with the slow-acting COMT gene excelled when performing mental tasks.?? Under those conditions, people with the fast-acting gene didn?t perform as well.

The outcome was reversed when people were subjected to a great deal of stress.? That?s because dopamine overloads the brains of people with the slow-acting gene? ? hampering their ability.? You see, dopamine rises in stressful situations.? So in this circumstance, the fast-acting gene keeps the brain?s dopamine at normal levels.

The COMT gene variants have also been shown to actually predict the activity of regions of the brain involved in cognition and emotional responses, said David Goldman, a National Institutes of Health scientist and author of ?Our Genes Our Choices.? This gene is an example of the genetic reasons why people?s brains work a little differently, and how the expression of these differences is altered by the contexts in which people find themselves, and choose.

How this all works has been studied in real life situations.? Researchers in Taiwan followed 779 students who took the national competency exam.? Under more stress than usual, students with the slow-acting enzymes scored eight percent lower on average than those with the fast-acting ones.? ?

There?s no need to worry though, it?s not either/or for most people.?? About 50 percent of all people inherit one of each gene variation from their parents.? So that means most people have medium acting enzymes. The other half is split between fast and slow acting genes.

Researchers also found that experience leveled the playing field.? The more practice someone had at performing tasks, the less likely they were to melt under pressure.

We know that practice makes perfect, but here are some other things that can help students reduce stress. ?

1.? Eat healthy.? Meals should include fruits and vegetables.
2.? Exercise regularly.
3.? Do things you enjoy often like, hobbies, sports and reading.
4.? Make sure you get enough sleep.
5.? Learn relaxation techniques like, meditation and deep breathing.

Research from the University of Missouri shows that being involved in school activities like, chess, spelling bees or science fairs gives students a chance to perform.? Some of these moments might be very stressful, but there?s a chance they could payoff in the end. ?

Airline to charge by weight of passenger, bags for flights

PAGO PAGO, American Samoa - A tiny Samoa airline is offering a new reason to drop extra weight before your next trip: Tickets sold not by the seat, but by kilogram.

Samoa Air planned on Wednesday to start pricing its first international flights based on the weight of its passengers and their bags. Depending on the flight, each kilogram (2.2 pounds) costs 93 cents to $1.06.

That means the average American man weighing 195 pounds with a 35 pound bag would pay $97 to go one-way between Apia, Samoa, and Pago Pago, American Samoa. Competitors typically charge $130 to $140 roundtrip for similar routes.

The weight-based pricing is not new to the airline, which launched in June. It has been using the pricing model since November, but in January the U.S. Department of Transportation approved its international route between American Samoa and Samoa.

The airline's chief executive, Chris Langton, said Tuesday that "planes are run by weight and not by seat, and travellers should be educated on this important issue. The plane can only carry a certain amount of weight and that weight needs to be paid. There is no other way."

Travellers in the region already are weighed before they fly because the planes used between the islands are small, said David Vaeafe, executive director of the American Samoa Visitors Bureau. Samoa Air's fleet includes two nine-seat planes for commercial routes and a three-seater for an air taxi service.

Langton said passengers who need more room will be given one row on the plane to ensure comfort.

The new pricing system would make Samoa Air the first to charge strictly by weight, a change that Vaeafe said is, "in many ways... a fair concept for passengers."

"For example, a 12- or 13-year-old passenger, who is small in size and weight, won't have to pay an adult fare, based on airline fares that anyone 12 years and older does pay the adult fare," he said.

Vaeafe said the pricing system has worked in Samoa but it's not clear whether it will be embraced by travellers in the U.S. territory.

Langton said the airline has received mixed responses from overseas travellers since it began promoting the pricing on its website and Facebook page.

Ana Faapouli, an American Samoa resident who frequently travels to Samoa, said the pricing scheme will likely be profitable for Samoa Air.

"Samoa Air is smart enough to find ways to benefit from this service as they will be competing against two other airlines," Faapouli said.

Pago Pago-based Inter Island Airways and Polynesian Airlines, which is owned by the Samoa government, also run flights between the country and American Samoa.

By keeping the beat, sea lion sheds new light on animals? movements to sound

Apr. 1, 2013 ? Move over dancing bears, Ronan the sea lion really does know how to boogie to the beat.

A California sea lion who bobs her head in time with music has given scientists the first empirical evidence of an animal that is not capable of vocal mimicry but can keep the beat, according to new research published by the American Psychological Association.

The study's authors suggest that their findings challenge current scientific theories that an animal's ability to synchronize its movements with sound are associated with the same brain mechanisms that allow for vocal mimicry in humans and some birds such as cockatoos, parrots, and budgerigars. The findings were published online April 1 in APA's Journal of Comparative Psychology.

"Understanding the cognitive capabilities of animals requires carefully controlled, well-designed experiments," said study co-author Colleen Reichmuth, PhD, with the Institute of Marine Sciences at the University of California at Santa Cruz. "This study is particularly rigorous because it examines, step-by-step, the learning conditions that supported the emergence of this complex behavior."

Ronan, a 3-year-old sea lion, demonstrated her ability to bob to the beat in six experiments led by doctoral candidate Peter Cook at the Long Marine Lab at UCSC.

"Dancing is universal among humans, and until recently, it was thought to be unique to humans as well," said Cook. "When some species of birds were found to have a similar capability for rhythmic movement, it was linked to their ability to mimic sound. Now we're seeing that even mammals with limited vocal ability can move in time with a beat over a broad range of sounds and tempos."

Ronan's first musical "dance" lesson was to the tune of a simplified section of John Fogerty's "Down on the Corner," the study said. Once Ronan was trained to bob her head to music, the researchers tested her with two pop songs, "Everybody" by the Backstreet Boys, and "Boogie Wonderland" by Earth, Wind and Fire. Without any prior exposure to the songs, Ronan was able to bob to the beat of both songs over the course of multiple trials, according to the study. She then showed that she could follow along to five different tempos of "Boogie Wonderland."

Ronan's bobbing skills markedly improved over the course of the trials and apparently endured, the study found. The researchers gave her a follow-up test a few weeks after the final session and she was successful in keeping the beat with each of the sounds previously used, maintaining a minimum of 60 consecutive bobs to each of the various beats.

At the beginning of the experiments, Ronan was first trained to move in time to a hand signal, which was replaced by a simple non-musical sound signal. When she successfully completed tests by bobbing her head to various rhythmic sounds, she was rewarded with a fish, the study said.

The researchers varied the types and speed of the sounds to verify that she was actually following the rhythm by bobbing her head. To rule out that she wasn't simply bobbing her head in response to the previous beat, they tested her using two computer-generated, metronome-like ticks -- one that did not miss a beat and the other that did. Ronan kept the beat going even when the metronome missed a beat, according to the study.

A video of Ronan can be watched at: http://www.youtube.com/watch?v=6yS6qU_w3JQ

Careers: What Does It Take to Become a Real Estate Agent? Part 6 ...

What is it really like to be a real estate agent, and what does it take to become one? We interviewed six Redfin Agents to find out why they chose real estate as a career and how they came to work at Redfin. Yesterday we profiled Chad Pluid, who managed a restaurant and worked in banking before joining Redfin. Today you?ll hear from?Bree Al-Rashid, a Redfin listing agent who worked as horse trainer, financial planner, and a real estate agent at another brokerage before joining the company.

If you?re looking for more agent info, be sure to check our entire series of real estate agent profiles and don?t hesitate to investigate open real estate jobs at Redfin.

bree-alrashid-270x360Bree Al-Rashid ? Listing Agent

Before joining Redfin, Bree worked as horse trainer, financial planner, and a real estate agent at another brokerage.

What did you do before you joined Redfin?

In college I ran a riding school and summer camp for kids to help pay for my tuition. One of my riding students ended up being a high level VP of a financial planning firm. She tried to hook me up with her son, but when that didn?t work out she said I should work for her firm. I did that for about two years, and stayed in the financial planning industry for six years.

What made you want to pursue your real estate license, and what was the process like?

I was tired of being stuck inside an office. My husband worked in real estate and was looking for help, so I decided to become licensed. We built a business together at Keller Williams, and then worked at RE/MAX for awhile.

Coming from an industry where there was a lot of licensing that you had to obtain, getting my license was pretty easy. You have to plan it out and do the classes, but if you?re a good test taker it?s fine. For most people who are interested in the industry, it?s totally feasible. You don?t have to have achieved high levels of math or analysis to be a licensed real estate professional.

How did you hear about Redfin, and why did you decide to apply?

A colleague at RE/MAX became a Redfin partner agent, and he introduced me to it. I was a partner agent for awhile, but when I decided I needed more balance in my life, I applied to Redfin. I started as a listing specialist, which provides the opportunity to keep regular hours. It has afforded a much more balanced life, especially with vacation time.

Do you worry about the market going up and down?

It hasn?t been a problem. I was always very lucky; I had as much or more business than I wanted.

What?s the best part of your job?

Redfin has a team of people that you can count on for support, so you can create balance in your life. Working on your own as an agent is a challenge; it?s hard to be a graphic designer, HR manager and bookkeeper all in one day and be successful. Now my day is spent marketing houses, negotiating contracts, and solving real estate-related problems. Redfin offers a chance to get your life back.

I love Redfin?s feel, the corporate culture. I love its weirdness ? how we?re thinking out of the box ? it?s super progressive, not stale and stodgy. I?m sick of it sounding like real estate is only for people who are over sixty. Redfin is really fresh. There?s also a lot of room for growth. If you want to work in other parts of the company, there are options. You?re not stuck being an agent for the rest of your life.

What skills do you think are important to be successful as a real estate agent?

People who come from a liberal arts background are often successful in real estate. 90% of what we do is good communications, reading into subtext, connecting the dots for human beings. People who are overly analytical struggle in this industry because they lose sight of the human component. There?s so much that can?t be measured in real estate; you can?t measure human emotions or the layout of a house.? It takes people skills and good communicators to be successful. Organization, problem solving, and the ability to be calm during stressful situations are also important.

What would you tell people who are thinking about becoming an agent?

If you?re getting into real estate as an independent broker and you have no background in the industry or a natural market to find business, it?s a tough business to get into. I came from financial planning, which has a similar struggle. It?s very difficult to find clients right off the bat. That?s what is unique about Redfin; if you have interest in the agency and you?re 22 years old, you can get into it right away. Or if you?re 50 and coming back for a second or third career, you can do the same thing. There are so many great built-in systems, and there?s an opportunity for mentorships. We don?t let people fail at Redfin.

At Redfin our motto is ?keep it weird.? What?s something ?weird? about you?

My pig won ?Grand Champion Market Hog? at the 1994 Oakhurst Fair. I didn?t get chicken pox until I was 14.? Then I gave them to my mom who was 41.?I can throw a Frisbee with my feet.

Egypt says will not discuss emergency loan with IMF

The saga of Biscuit, a 37-pound feline from the St. Louis area, isn't quite done yet. The tubby tabby had to find another home after his first one didn't work out after leaving an area shelter in mid-March. The St. Louis Post-Dispatch reports Ed and Lisa Pyatt of Eureka, Mo., were the lucky recipients of Biscuit after the City of St. Charles Animal Control Services reviewed more than 110 offers for homes. The huge cat didn't get along with the Pyatts' other cat. Luckily, a specialized animal shelter stepped in to help.

(AP) ? Mexican drug cartels whose operatives once rarely ventured beyond the U.S. border are dispatching some of their most trusted agents to live and work deep inside the United States ? an emboldened presence that experts believe is meant to tighten their grip on the world's most lucrative narcotics market and maximize profits.

If left unchecked, authorities say, the cartels' move into the American interior could render the syndicates harder than ever to dislodge and pave the way for them to expand into other criminal enterprises such as prostitution, kidnapping-and-extortion rackets and money laundering.

Cartel activity in the U.S. is certainly not new. Starting in the 1990s, the ruthless syndicates became the nation's No. 1 supplier of illegal drugs, using unaffiliated middlemen to smuggle cocaine, marijuana and heroin beyond the border or even to grow pot here.

But a wide-ranging Associated Press review of federal court cases and government drug-enforcement data, plus interviews with many top law enforcement officials, indicate the groups have begun deploying agents from their inner circles to the U.S. Cartel operatives are suspected of running drug-distribution networks in at least nine non-border states, often in middle-class suburbs in the Midwest, South and Northeast.

"It's probably the most serious threat the United States has faced from organized crime," said Jack Riley, head of the Drug Enforcement Administration's Chicago office.

The cartel threat looms so large that one of Mexico's most notorious drug kingpins ? a man who has never set foot in Chicago ? was recently named the city's Public Enemy No. 1, the same notorious label once assigned to Al Capone.

The Chicago Crime Commission, a non-government agency that tracks crime trends in the region, said it considers Joaquin "El Chapo" Guzman even more menacing than Capone because Guzman leads the deadly Sinaloa cartel, which supplies most of the narcotics sold in Chicago and in many cities across the U.S.

Years ago, Mexico faced the same problem ? of then-nascent cartels expanding their power ? "and didn't nip the problem in the bud," said Jack Killorin, head of an anti-trafficking program in Atlanta for the Office of National Drug Control Policy. "And see where they are now."

Riley sounds a similar alarm: "People think, 'The border's 1,700 miles away. This isn't our problem.' Well, it is. These days, we operate as if Chicago is on the border."

Border states from Texas to California have long grappled with a cartel presence. But cases involving cartel members have now emerged in the suburbs of Chicago and Atlanta, as well as Columbus, Ohio, Louisville, Ky., and rural North Carolina. Suspects have also surfaced in Indiana, Michigan, Minnesota and Pennsylvania.

Mexican drug cartels "are taking over our neighborhoods," Pennsylvania Attorney General Kathleen Kane warned a legislative committee in February. State Police Commissioner Frank Noonan disputed her claim, saying cartels are primarily drug suppliers, not the ones trafficking drugs on the ground.

For years, cartels were more inclined to make deals in Mexico with American traffickers, who would then handle transportation to and distribution within major cities, said Art Bilek, a former organized crime investigator who is now executive vice president of the crime commission.

As their organizations grew more sophisticated, the cartels began scheming to keep more profits for themselves. So leaders sought to cut out middlemen and assume more direct control, pushing aside American traffickers, he said.

Beginning two or three years ago, authorities noticed that cartels were putting "deputies on the ground here," Bilek said. "Chicago became such a massive market ... it was critical that they had firm control."

To help fight the syndicates, Chicago recently opened a first-of-its-kind facility at a secret location where 70 federal agents work side-by-side with police and prosecutors. Their primary focus is the point of contact between suburban-based cartel operatives and city street gangs who act as retail salesmen. That is when both sides are most vulnerable to detection, when they are most likely to meet in the open or use cellphones that can be wiretapped.

Others are skeptical about claims cartels are expanding their presence, saying law-enforcement agencies are prone to exaggerating threats to justify bigger budgets.

David Shirk, of the University of San Diego's Trans-Border Institute, said there is a dearth of reliable intelligence that cartels are dispatching operatives from Mexico on a large scale.

"We know astonishingly little about the structure and dynamics of cartels north of the border," Shirk said. "We need to be very cautious about the assumptions we make."

Statistics from the DEA suggest a heightened cartel presence in more U.S. cities. In 2008, around 230 American communities reported some level of cartel presence. That number climbed to more than 1,200 in 2011, the most recent year for which information is available, though the increase is partly due to better reporting.

Dozens of federal agents and local police interviewed by the AP said they have identified cartel members or operatives using wiretapped conversations, informants or confessions. Hundreds of court documents reviewed by the AP appear to support those statements.

"This is the first time we've been seeing it ? cartels who have their operatives actually sent here," said Richard Pearson, a lieutenant with the Louisville Metropolitan Police Department, which arrested four alleged operatives of the Zetas cartel in November in the suburb of Okolona.

People who live on the tree-lined street where authorities seized more than 2,400 pounds of marijuana and more than $1 million in cash were shocked to learn their low-key neighbors were accused of working for one of Mexico's most violent drug syndicates, Pearson said.

One of the best documented cases is Jose Gonzalez-Zavala, who was dispatched to the U.S. by the La Familia cartel, according to court filings.

In 2008, the former taxi driver and father of five moved into a spacious home at 1416 Brookfield Drive in a middle-class neighborhood of Joliet, southwest of Chicago. From there, court papers indicate, he oversaw wholesale shipments of cocaine in Illinois, Wisconsin and Indiana.

Wiretap transcripts reveal he called an unidentified cartel boss in Mexico almost every day, displaying the deference any midlevel executive might show to someone higher up the corporate ladder. Once he stammered as he explained that one customer would not pay a debt until after a trip.

"No," snaps the boss. "What we need is for him to pay."

The same cartel assigned Jorge Guadalupe Ayala-German to guard a Chicago-area stash house for $300 a week, plus a promised $35,000 lump-sum payment once he returned to Mexico after a year or two, according to court documents.

Ayala-German brought his wife and child to help give the house the appearance of an ordinary family residence. But he was arrested before he could return home and pleaded guilty to multiple trafficking charges. He will be sentenced later this year.

Socorro Hernandez-Rodriguez was convicted in 2011 of heading a massive drug operation in suburban Atlanta's Gwinnett County. The chief prosecutor said he and his associates were high-ranking figures in the La Familia cartel ? an allegation defense lawyers denied.

And at the end of February outside Columbus, Ohio, authorities arrested 34-year-old Isaac Eli Perez Neri, who allegedly told investigators he was a debt collector for the Sinaloa cartel.

An Atlanta attorney who has represented reputed cartel members says authorities sometimes overstate the threat such men pose.

"Often, you have a kid whose first time leaving Mexico is sleeping on a mattress at a stash house playing Game Boy, eating Burger King, just checking drugs or money in and out," said Bruce Harvey. "Then he's arrested and gets a gargantuan sentence. It's sad."

Typically, cartel operatives are not U.S. citizens and make no attempt to acquire visas, choosing instead to sneak across the border. They are so accustomed to slipping back and forth between the two countries that they regularly return home for family weddings and holidays, Riley said.

Because cartels accumulate houses full of cash, they run the constant risk associates will skim off the top. That points to the main reason cartels prefer their own people: Trust is hard to come by in their cutthroat world. There's also a fear factor. Cartels can exert more control on their operatives than on middlemen, often by threatening to torture or kill loved ones back home.

Danny Porter, chief prosecutor in Gwinnett County, Ga., said he has tried to entice dozens of suspected cartel members to cooperate with American authorities. Nearly all declined. Some laughed in his face.

"They say, 'We are more scared of them (the cartels) than we are of you. We talk and they'll boil our family in acid,'" Porter said. "Their families are essentially hostages."

Citing the safety of his own family, Gonzalez-Zavala declined to cooperate with authorities in exchange for years being shaved off his 40-year sentence.

In other cases, cartel brass send their own family members to the U.S.

"They're sometimes married or related to people in the cartels," Porter said. "They don't hire casual labor." So meticulous have cartels become that some even have operatives fill out job applications before being dispatched to the U.S., Riley added.

In Mexico, the cartels are known for a staggering number of killings ? more than 50,000, according to one tally. Beheadings are sometimes a signature.

So far, cartels don't appear to be directly responsible for large numbers of slayings in the United States, though the Texas Department of Public Safety reported 22 killings and five kidnappings in Texas at the hands of Mexican cartels from 2010 through mid- 2011.

Still, police worry that increased cartel activity could fuel heightened violence.

In Chicago, the police commander who oversees narcotics investigations, James O'Grady, said street-gang disputes over turf account for most of the city's uptick in murders last year, when slayings topped 500 for the first time since 2008. Although the cartels aren't dictating the territorial wars, they are the source of drugs.

Riley's assessment is stark: He argues that the cartels should be seen as an underlying cause of Chicago's disturbingly high murder rate.

"They are the puppeteers," he said. "Maybe the shooter didn't know and maybe the victim didn't know that. But if you follow it down the line, the cartels are ultimately responsible."
