'Being Mandela:' Granddaughters dish on show

NEW YORK (AP) — The newest reality television show is in some ways like any other: mother and daughters, sibling rivalry, family gossip and talk of Big Grandpa, who is very strict but loves it when his great-grandchildren are around making a racket. But that's where the twist comes in: Big Grandpa is Nelson Mandela, the anti-apartheid legend.

"Being Mandela," a new series premiering Sunday on COZI TV, invites U.S. audiences into the lives of Zaziwe Dlamini-Manaway and Swati Dlamini, the fashionable, 30-something granddaughters of Mandela and Winnie Madikizela-Mandela. The 94-year-old former South African president, who recently was treated for a lung infection and had surgery to remove gallstones, does not appear in the series but his controversial ex-wife — "Big Mommy" to her grandchildren — does and seems to relish it.

If the Mandela clan seems like an odd subject for a reality show, the granddaughters make no apologies.

"We get asked this question a lot. Is this not going to tarnish the name and is this not going to be bad for the name?" Swati Dlamini said in an interview with The Associated Press in New York, where she and her sister were promoting the show. "But our grandparents have always said to us, this is our name too, and we can do what we think is best fitting with the name, as long as we treat it with respect and integrity."

The 13-episode first season follows the two women as they try to carry on the family legacy while juggling motherhood in Johannesburg.

The sisters, who spent most of their childhood in exile in the United States, make an emotional visit to the prison on Robben Island where their grandfather spent 18 of the 27 years he was imprisoned by South Africa's white-ruled government. Swati works on publishing the prison diaries that her grandmother wrote but now cannot bear to read.

The women, along with two brothers, also become the latest famous names to launch a fashion line, called "Long Walk to Freedom" in honor of their grandfather's autobiography. Their lives are special and glamorous and they know it. They hope that U.S. audiences — COZI TV is a new network launched by NBC Owned Television Stations — will see a vibrant and modern side of South Africa through their eyes.

They also bicker. The family, especially Winnie Madikizela-Mandela, loves to gossip about when Swati, the single mother of a 4-year-old daughter, is going to get married. Swati is furious when Zaziwe, despite being sworn to secrecy, blurts to their grandmother that her sister is dating someone. Zaziwe, 35, is married to an American businessman and has three children.

The sisters are the daughters of Zenani Mandela and Prince Thumbumuzi Dlamini of Swaziland. But parents everywhere will delight in seeing that being royal doesn't help them face toddler tantrums or get older children out of bed and into school uniforms.

Big Grandpa and Big Mommy are into the show, the sisters insisted.

Mandela will definitely watch it, they said. The Nobel Peace Prize winner apparently sort of likes reality TV.

"You'll be interested to know that he loves Toddlers and Tiarras," said Swati, laughing in reference to the TLC series about child beauty pageants.

"Because of the kids! He just loves children," Zaziwe added quickly.

The sisters said their grandfather is "happy and healthy."

Zaziwe showed a Feb. 2 photograph of Mandela at home, flashing his familiar smile, with his youngest great-grandchild on his lap — Zaziwe's one-year-old son. The picture is a rare public image of Mandela, whose last appearance on a major stage was during the 2010 World Cup soccer tournament in South Africa.

Mandela, who always lamented his long separation from his family during his imprisonment, is happiest these days when his offspring are running around being loud, his granddaughters said.

"We're in and out of the house. We're loud and he loves the noise," Zaziwe said.

The granddaughters say their grandfather — to the world, a symbol of integrity and magnanimity — holds the family to high standards and sets rules for when the children should be home and when dinner should start.

"He's a very strict person. Most people wouldn't think that but he really, really is," Zaziwe said.

The sisters are closer to Winnie Madikizela-Mandela, who divorced Mandela in 1997. Their adoring description of their grandmother as the doting matriarch stands in contrast with her checkered public image. Beloved by many poor urban blacks, Madikizela-Mandela also faces accusations that she and her bodyguard unit committed 18 killings in the 1980s. She denies it.

"She's fun. She never says no to us. I don't think I've ever heard my grandmother say no to us," Zaziwe said.

Still, the series shows Big Mommy clearly taking charge of the family. She marches into the hospital room where Zaziwe gave birth to Zen with a list of possible names for the baby boy.

The sisters say it was only after Mandela retired from public life that they started to get to know their grandfather.

"Our grandfather always told us that he belongs to the country and he's of service to the country and he doesn't belong to us as a family. And that's the sacrifice he's made for the country and that what he's told us as far as I can remember," Swati said.

Well: Old Age and Motorcycles Are a Dangerous Mix

If you’re over 40 and planning to hop on a motorcycle, take care. Compared with younger riders, the odds of being seriously injured are high.

That is the message of a new study, published this week in the journal Injury Prevention, which found that older bikers are three times as likely to be severely injured in a crash as younger riders.

The percentage of older bikers on the road is quickly rising, and their involvement in accidents is a growing concern. Nationwide, from 1990 to 2003, the percentage of motorcyclists over age 50 soared from roughly 1 in 10 to about 1 in 4. At the same time, the average age of riders involved in motorcycle crashes has also been climbing. Injury rates among those 65 and older jumped 145 percent from 2000 to 2006 alone.

Because of the increase in motorcycle ridership among older Americans, the researchers, led by Tracy Jackson, a graduate student in the epidemiology department at Brown University, wanted a closer look at their injury patterns. So she and her colleagues combed through a federal database of motorcycle crashes that were serious enough to require emergency medical care. That yielded about 1.5 million incidents involving motorcyclists 20 or older from 2001 to 2008.

The researchers then split them into groups: those in their 20s and 30s, another group between 40 and 59, and those 60 and older.

Over all, the study showed that injury rates for all three groups were on the rise. But the rise was steepest for the oldest riders. Compared with the youngest motorcyclists, those who were 60 and older were two and a half times as likely to end up with serious injuries, and three times as likely to be admitted to a hospital. The riders who were middle age were twice as likely as their younger counterparts to be hospitalized.

For older riders, the consequences of a collision were also especially alarming. Older and middle-aged bikers were more likely to sustain fractures and dislocations, and they had a far greater chance of ending up with injuries to internal organs, including brain damage.

The researchers speculated that it was very likely that a number of factors played a role in older riders’ higher injury rates. For one, declines in vision and reaction time may make older riders more prone to mistakes that end up in collisions. Another theory is that older riders tend to ride bigger bikes, “which may be more likely to roll or turn over,” Ms. Jackson said.

Then there is the greater fragility that comes with age. Older riders may be involved in the same types of accidents as younger riders, Ms. Jackson said, but in some cases, a collision that a 20-year-old would walk away from might send a 65-year-old to the hospital.

“Your bones become more brittle, and you lose muscle mass as you get older,” she said. “It could just be a matter of aging and the body being less durable.”

South Korean firm aims for the sky in L.A.

Ambitious South Korean enterprises continue to make noise on the global economic stage.

Electronics giant Samsung is giving Apple fits in markets across the globe with its hot-selling smartphones and tablets. Seoul-based Hyundai and Kia have been among the world's fastest-growing automakers in recent years. Portly singer Psy put South Korea on the pop culture map with his monster hit “Gangnam Style,” which has become the most popular video of all time on YouTube with nearly 1.3 billion views.

So it was only natural that South Korea's top airline, Korean Air, on Thursday took the wraps off its design for a dramatic, skyline-changing tower for downtown Los Angeles. The $1-billion skyscraper is to become the tallest building west of the Mississippi River — and a symbol of South Korea's status as an up-and-coming economic powerhouse.

The 73-story hotel and office building will include 900 guest rooms, double-decker elevators and an observation deck that will afford views of the Pacific Ocean. Slated to replace the old Wilshire Grand Hotel at Wilshire Boulevard at Figueroa Street, the new building will be slightly taller than the nearby U.S. Bank Tower, which has held the title of tallest building west of Chicago since 1989.

Originally planned as two smaller towers when it was announced four years ago, the Korean Air plan has morphed into a single tower that will give the Seoul company bragging rights to the highest skyscraper on the West Coast.

Experts said that's in keeping with South Korea's hard-charging business ethos. The skyscraper, currently dubbed the Wilshire Grand, is an outgrowth of a competitive corporate culture that has come to dominate the South Korean economy over the last 30 years, according to UC Riverside Ethnic Studies professor Edward Taehan Chang.

After the nation endured poverty, dictatorship and political unrest during much of the 20th century, attaining superlatives has become part of the country's fabric, Chang said. Corporations strive to dominate their industries, while younger generations take pride in the near universality of South Korea's popular culture.

“They always want to reach for No. 1 status,” Chang said. “The rapid economic growth has been about striving for the top spot.”

Korean Air is already at work dismantling the closed 1950s-era Wilshire Grand Hotel to make way for the glass-clad tower, which is expected to be completed in 2017. Korean Air has provided airline service to Los Angeles for more than 40 years and has owned the Wilshire Grand since 1989.

Korean Air is the flagship company of Hanjin Group, one of South Korea's largest conglomerates. Hanjin has interests in land, sea and air transportation as well as construction, heavy industry, finance and information services. A high-end hotel fits well with Korean Air's operations in Los Angeles: The company makes parts for airplanes, flies the planes here as the busiest Asian carrier at Los Angeles International Airport, runs travel agencies that book the tickets and operates a catering business that serves the food on the planes.

“The new Wilshire Grand is an investment that makes sense, and we are excited to continue our relationship with this great city,” Korean Air Chairman Y.H. Cho said Thursday at the offices of AC Martin Partners, the project's architect.

The sail-shaped skyscraper will light up at night and dwarf many of its neighbors. Most of the building will be devoted to a hotel, though an operator has yet to be named. Arriving guests would be whisked by high-speed elevators to the “sky lobby” on the 70th floor for check-in.

According to the plan, the 71st floor will be a restaurant. The floor above that will house window-washing gear and engineering equipment, clearing the top floor for an infinity swimming pool and observation deck.

Near street level will be about three floors of restaurants and shops, topped by 30 floors of offices for rent. Elevators will be double-decked, carrying two stacked cabs of passengers for additional capacity during peak hours.

Perched at the very top of the building will be a decorative “crown” and a mast-like spire that will have embedded LED lighting that can change colors. The display will be eye-catching and visible for miles, but it will not be used for advertising, said Christopher Martin, chief executive of AC Martin.

“It's not Coke bottles, it's art,” he said.

With the spire reaching to 1,100 feet, the Wilshire Grand would become one of the tallest structures in the country, surpassing the 1,046-foot Chrysler Building in New York, which has 77 stories.

The contemporary design of the Wilshire Grand, with its floor-to-ceiling windows, is intended to set it apart from surrounding granite-clad office towers, said architect David Martin, who is Christopher Martin's cousin.

He hopes the building, which is to include 400,000 square feet of office space, will reflect the city better than the last generation of skyscrapers does. The Wilshire Grand, for instance, will have operable windows in its guest rooms and offices.

“This is about the culture and climate of L.A.,” Martin said. “We are creating a sense of place, only it's 1,000 feet up in the air.”

AC Martin also designed the Figueroa-at-Wilshire high-rise across the street from the Wilshire Grand in 1990. The family firm was the primary architect of Los Angles City Hall in the 1920s.

Work on the new skyscraper will create 11,000 union construction jobs, Korean Air's Cho said, and employ 1,700 workers when it opens in four years. The project has obtained most development approvals from L.A. city officials.

Cho, who lives in Seoul and has a home in Newport Beach, is on the board of trustees at USC, where his children attended college and where he obtained his MBA.

“L.A. is like a second home,” Cho said.

The 936-room Wilshire Grand, built in 1952, was originally a Hotel Statler and later a Hilton. Once one of the city's best hotels, it was most recently a mid-market inn catering to conventioneers and tour groups from overseas before it closed at the end of 2011.

The property is a few blocks north of Staples Center.

L.A. County Sheriff's Department intends to fire seven deputies

Seven Los Angeles County sheriff's deputies have been notified that the department intends to fire them for belonging to a secret law enforcement clique that allegedly celebrated shootings and branded its members with matching tattoos, officials said.

The Times reported last year about the existence of the clique, dubbed the Jump Out Boys, and the discovery of a pamphlet that described the group's creed, which required aggressive policing and awarded tattoo modifications for police shootings.

The seven worked on an elite gang-enforcement team that patrols neighborhoods where violence is high. The team makes a priority of taking guns off the street, officials said.

The Sheriff's Department has a long history of secret cliques with members of the groups having reached high-ranking positions within the agency. Sheriff officials have sought to crack down on the groups, fearing that they tarnished the department's reputation and encouraged unethical conduct.

In the case of the Jump Out Boys, sheriff's investigators did not uncover any criminal behavior. But, sources said, the group clashed with department policies and image.

Their tattoos, for instance, depicted an oversize skull with a wide, toothy grimace and glowing red eyes. A bandanna with the unit's acronym is wrapped around the skull. A bony hand clasps a revolver. Smoke would be tattooed over the gun's barrel for members who were involved in at least one shooting, officials said.

One member, who spoke to The Times and requested anonymity, said the group promoted only hard work and bravery. He dismissed concerns about the group's tattoo, noting that deputies throughout the department get matching tattoos. He said there was nothing sinister about their creed or conduct. The deputy, who was notified of the department's intent to terminate him, read The Times several passages from the pamphlet, which he said supported proactive policing.

"We are alpha dogs who think and act like the wolf, but never become the wolf," one passage stated, comparing criminals to wolves. Another passage stated, "We are not afraid to get our hands dirty without any disgrace, dishonor or hesitation... sometimes (members) need to do the things they don't want to in order to get where they want to be."

Department spokesman Steve Whitmore said starting the termination process shows that Sheriff Lee Baca "does not take any of this lightly and will move forward with the appropriate action."

Investigators were less concerned about the tattoos, and more focused on the suspected admiration they showed for officer-involved shootings, which are expected to be events of last resort. The deputy told The Times, however, that investigators reviewed their shootings and arrests and found nothing unlawful.

"We get called a gang within the badge? It's unfair," he said. "People want to say you have a tattoo. So do fraternities. Go to Yale. Are they a gang?.... Boy Scouts have patches and they have mission statements, and so do we."

"We do not glorify shootings," he continued. "What we do is commend and honor the shootings. I have to remember them because it can happen any time, any day. I don't want to forget them because I'm glad I'm alive."

If the firings are upheld, it would be one of the largest terminations over one incident in the department's history. In 2011, the department fired about half a dozen deputies who were also said to have formed a clique. Those deputies worked on the third floor of Men's Central Jail and allegedly threw gang-like three-finger hand signs. They were fired after they fought two fellow deputies at an employee Christmas party and allegedly punched a female deputy in the face.

As part of the widening federal investigation of the Sheriff's Department, a criminal grand jury recently subpoenaed the agency for materials relating to deputy cliques, specifically citing several of the groups including the "3000 boys" and the Jump Out Boys.

When the pamphlet revealing the existence of the Jump Out Boys was initially found, officials didn't know if the group was real. But eventually, one member came forward and named the others, according to an official who asked for anonymity because he was not authorized to speak to the media.

The seven deputies can fight the department's decision to fire them.

Selena Gomez works the front row at Neo show

NEW YORK (AP) — Selena Gomez sat front and center at the fashion show to preview the first collection in her collaboration with Adidas' streetwear Neo label.

But the runway at Wednesday evening's show was a next-gen catwalk: Teenager bloggers were charged with styling the outfits instead of industry professionals.

Gomez thanked them as she stood on stage at the end of the show. She was flanked by models in denim shorts, Bermudas, slouchy sweats and T-shirts that read "Pirate Love." There were a few graffiti prints sprinkled in, and some varsity jackets.

The clothes, mostly in sunny yellow, bright pink and navy, were more surf than sport, which is Adidas' normal niche.

The show was very briefly interrupted by a protester trying to hand out leaflets about sweatshops.

Well: Think Like a Doctor: A Confused and Terrified Patient

The Challenge: Can you solve the mystery of a middle-aged man recovering from a serious illness who suddenly becomes frightened and confused?

Every month the Diagnosis column of The New York Times Magazine asks Well readers to sift through a difficult case and solve a diagnostic riddle. Below you will find a summary of a case involving a 55-year-old man well on his way to recovering from a series of illnesses when he suddenly becomes confused and paranoid. I will provide you with the main medical notes, labs and imaging results available to the doctor who made the diagnosis.

The first reader to figure out this case will get a signed copy of my book, “Every Patient Tells a Story,” along with the satisfaction of knowing you solved a case of Sherlockian complexity. Good luck.

The Presenting Problem:

A 55-year-old man who is recovering from a devastating injury in a rehabilitation facility suddenly becomes confused, frightened and paranoid.

The Patient’s Story:

The patient, who was recovering from a terrible injury and was too weak to walk, had been found on the floor of his room at the extended care facility, raving that there were people out to get him. He was taken to the emergency room at the Waterbury Hospital in Connecticut, where he was diagnosed with a urinary tract infection and admitted to the hospital for treatment. Doctors thought his delirium was caused by the infection, but after 24 hours, despite receiving the appropriate antibiotics, the patient remained disoriented and frightened.

A Sister’s Visit:

The man’s sister came to visit him on his second day in the hospital. As she walked into the room she was immediately struck by her brother’s distress.

“Get me out of here!” the man shouted from his hospital bed. “They are coming to get me. I gotta get out of here!”

His blue eyes darted from side to side as if searching for his would-be attackers. His arms and legs shook with fear. He looked terrified.

For the past few months, the man had been in and out of the hospital, but he had been getting better — at least he had been improving the last time his sister saw him, the week before. She hurried into the bustling hallway and found a nurse. “What the hell is going on with my brother?” she demanded.

A Long Series of Illnesses:

Three months earlier, the patient had been admitted to that same hospital with delirium tremens. After years of alcohol abuse, he had suddenly stopped drinking a couple of days before, and his body was wracked by the sudden loss of the chemical he had become addicted to. He’d spent an entire week in the hospital but finally recovered. He was sent home, but he didn’t stay there for long.

The following week, when his sister hadn’t heard from him for a couple of days, she forced her way into his home. There she found him, unconscious, in the basement, at the bottom of his staircase. He had fallen, and it looked as if he may have been there for two, possibly three, days. He was close to death. Indeed, in the ambulance on the way to the hospital, his heart had stopped. Rapid action by the E.M.T.’s brought his heart back to life, and he made it to the hospital.

There the extent of the damage became clear. The man’s kidneys had stopped working, and his body chemistry was completely out of whack. He had a severe concussion. And he’d had a heart attack.

He remained in the intensive care unit for nearly three weeks, and in the hospital another two weeks. Even after these weeks of care and recovery, the toll of his injury was terrible. His kidneys were not working, so he required dialysis three times a week. He had needed a machine to help him breathe for so long that he now had to get oxygen through a hole that had been cut into his throat. His arms and legs were so weak that he could not even lift them, and because he was unable even to swallow, he had to be fed through a tube that went directly into his stomach.

Finally, after five weeks in the hospital, he was well enough to be moved to a short-term rehabilitation hospital to complete the long road to recovery. But he was still far from healthy. The laughing, swaggering, Harley-riding man his sister had known until that terrible fall seemed a distant memory, though she saw that he was slowly getting better. He had even started to smile and make jokes. He was confident, he had told her, that with a lot of hard work he could get back to normal. So was she; she knew he was tough.

Back to the Hospital:

The patient had been at the rehab facility for just over two weeks when the staff noticed a sudden change in him. He had stopped smiling and was no longer making jokes. Instead, he talked about people that no one else could see. And he was worried that they wanted to harm him. When he remained confused for a second day, they sent him to the emergency room.

You can see the records from that E.R. visit here.

The man told the E.R. doctor that he knew he was having hallucinations. He thought they had started when he had begun taking a pill to help him sleep a couple of days earlier. It seemed a reasonable explanation, since the medication was known to cause delirium in some people. The hospital psychiatrist took him off that medication and sent him back to rehab that evening with a different sleeping pill.

Back to the Hospital, Again:

Two days later, the patient was back in the emergency room. He was still seeing things that weren’t there, but now he was quite confused as well. He knew his name but couldn’t remember what day or month it was, or even what year. And he had no idea where he was, or where he had just come from.

When the medical team saw the patient after he had been admitted, he was unable to provide any useful medical history. His medical records outlined his earlier hospitalizations, and records from the nursing home filled in additional details. The patient had a history of high blood pressure, depression and alcoholism. He was on a long list of medications. And he had been confused for the past several days.

On examination, he had no fever, although a couple of hours earlier his temperature had been 100.0 degrees. His heart was racing, and his blood pressure was sky high. His arms and legs were weak and swollen. His legs were shaking, and his reflexes were very brisk. Indeed, when his ankle was flexed suddenly, it continued to jerk back and forth on its own three or four times before stopping, a phenomenon known as clonus.

His labs were unchanged from the previous visit except for his urine, which showed signs of a serious infection. A CT scan of the brain was unremarkable, as was a chest X-ray. He was started on an intravenous antibiotic to treat the infection. The thinking was that perhaps the infection was causing the patient’s confusion.

You can see the notes from that second hospital visit here.

His sister had come to visit him the next day, when he was as confused as he had ever been. He was now trembling all over and looked scared to death, terrified. He was certain he was being pursued.

That is when she confronted the nurse, demanding to know what was going on with her brother. The nurse didn’t know. No one did. His urinary tract infection was being treated with antibiotics, but he continued to have a rapid heart rate and elevated blood pressure, along with terrifying hallucinations.

Solving the Mystery:

Can you figure out why this man was so confused and tremulous? I have provided you with all the data available to the doctor who made the diagnosis. The case is not easy — that is why it is here. I’ll post the answer on Friday.

---

Rules and Regulations: Post your questions and diagnosis in the comments section below.. The correct answer will appear Friday on Well. The winner will be contacted. Reader comments may also appear in a coming issue of The New York Times Magazine.

Pitfalls seen in growth of part-time work

Although the state's unemployment rate is at its lowest level in almost four years and the number of employed Californians is growing, labor experts see a different reality: Full-time work has faded in many industries.

Nubia Calderón Barillas, 32, left a job in retail in May for a housekeeping job at the Holiday Inn LAX that promised better pay and steady work.

But nearly nine months later, the mother of three said, she rarely works more than two days a week. She has asked for more hours, she said, but to no avail, even in an industry that set a new peak employment level last year.

"It's been difficult lately," she said. "I practically didn't work all of December except for the holidays."

California employers picked up the rate of hiring during 2012 — at times at nearly twice the rate of the country as a whole. But a significant portion of those jobs are less than full time, according to federal data released last week.

The number of people involuntarily working part time nationwide has grown to 7.9 million, an 80% increase from 2006, data from the Bureau of Labor Statistics show.

That trend is particularly pronounced in the Golden State, which saw the number of involuntary part-time workers swell to 1.3 million, up 126% from 585,100 in 2006. Only four other states, Nevada and Florida among them, had higher rates of involuntary part-time workers.

Various industries are increasingly relying on part-time workers and other contingent employees, such as temporary workers, to save money, said Michael Bernick, a Milken Institute fellow who studies labor markets.

"As you have more and more costs associated with full-time workers in terms of healthcare or other costs, employers look for alternative ways to reduce costs," Bernick said. "One way is on-demand and part-time work."

The increase isn't limited to industries that typically employ part-time workers, such as leisure and hospitality. Other sectors with strong job growth, such as professional and business services, have also seen a rise in part-time workers as employers aim to keep payroll costs down, Bernick said.

Nationwide, the number of involuntary part-time workers in professional and business services, which includes white-collar occupations such as accountants and lawyers, nearly doubled to 711,000 last year from 367,000 in 2007. A sector-by-sector breakdown is unavailable for California because the sample size of the household survey that the federal data rely on is too small.

Part-time work is common in California's leisure and hospitality sector, which added almost 61,000 jobs since December 2011, accounting for more than a quarter of the state's net jobs created in that time period.

Growth of low-wage industries such as hospitality provides work opportunities for people with limited education, even if the work is only part time, said Jerry Nickelsburg, senior economist at the UCLA Anderson Forecast.

"We shouldn't look with dismay" on the rapid growth of a sector that is so dependent on part-time work, he said. "If that were the only sector we were growing, then that would be worrisome."

Tom Walsh, president of Unite Here Local 11, a union representing hospitality workers in Los Angeles and Orange counties, said in negotiations with employers, his group has pushed for workers' hours to be maximized.

Although full-time work sometimes isn't ensured, Walsh said, employers are urged to give part-time workers as many hours as possible.

"I think it's an example of certain employers being penny wise but pound foolish," he said. "They figure they can save money by having more part-time workers and having low pay. If they don't change that, folks are going to take jobs somewhere else the first chance they get."

The long-term implication of part-time work, economists said, is growing wage disparities and the risk of dampening consumer spending, a major driver of the economy. Part-time workers also are more likely to rely on state aid, such as food stamps, to make ends meet.

Kellie Flowers moved to Los Angeles late last year hoping to find work as an event coordinator or wardrobe stylist.

But full-time work has been elusive, even with a college degree.

The 30-year-old Virginia native managed to land two part-time jobs when she first relocated, one at a Manhattan Beach boutique and the other at a running store.

She earned $10 per hour at both jobs but didn't have benefits or health insurance.

"It was very hard working two jobs," she said. "You definitely don't have any spending money."

Flowers recently started a new job, selling spa packages, on commission. She sells between six to 10 a day, earning $15 for each.

"I'm going to look for other jobs that make me happier. Until then I just need to make money," she said.

Meanwhile, Barillas, the Holiday Inn housekeeper, said she hopes she'll eventually work more hours.

She and her husband are falling behind on utility bills at the one-bedroom Koreatown apartment they share with their three children. She recently applied for food stamps, a decision she said was embarrassing.

"I've always had work," she said. "I used to think people on food stamps just didn't want to work, but now I find myself with the need to ask for help."

Child porn suspect indicted by federal grand jury

A North Hills woman whom authorities allege plied a young girl with crack cocaine and photographed her being sexually abused by an older man was indicted Tuesday on federal charges of producing child pornography and sex trafficking.

Letha Montemayor Tucker was named Tuesday in a four-count indictment returned by a federal grand jury. If convicted of all the charges, Tucker would face a mandatory minimum federal sentence of 10 years and could get up to life in prison, authorities said.

The charges come a month after authorities sought the public's help in the investigation by releasing photographs of a man and woman depicted in a set of widely circulated child pornography photos.

Tips started pouring in immediately after the photos were released, investigators said.

Tucker, who goes by the name Butterfly, was located about 10 hours after the release of the photos and taken into custody, said Claude Arnold, special agent in charge for Homeland Security Investigations in Los Angeles, a division of U.S. Immigration and Customs Enforcement.

The alleged victim, who was about 12 when the photos were taken, was found within a week of the case going public, Arnold said. She is an adult now and is cooperating with authorities, he said.

In addition to photographing the girl being sexually abused by the man, authorities said, Tucker also committed sex acts with the alleged victim.

The photos were part of a child pornography collection known as the "Jen Series."

The 40-plus photos were first discovered by investigators in the Chicago area in 2007. Investigators said images in the series have been reported about 300 times and have been found on computers across the country.

The victim "didn't even know these images were out there," Arnold said.

"The horror of child pornography is it's for life, the victimization," Arnold said. "Once the photos are there in cyberspace, they're there forever."

The girl, identified in court records only by the initials J.M.M., lived in the same Los Angeles County residential hotel as Tucker, who worked as a prostitute, authorities said.

Around 2000 or 2001, the girl stopped attending school regularly and spent more and more time in Tucker's room, smoking crack cocaine Tucker provided, according to the indictment.

The girl was present when Tucker engaged in prostitution with clients and was usually high when this happened, authorities allege. Tucker instructed the child to take off her clothes in front of the clients, prosecutors alleged in court papers.

The faces of Tucker and the girl are "clearly visible" in the photos, according to the indictment. Tucker had an eyebrow piercing and a tattoo of a sleeping cat behind her shoulder, which made her easier to identify, authorities said.

The face of the man, however, is blacked out in the photographs. Authorities are still trying to identify the man, Arnold said.

"Obviously, we want him also to answer for his crimes," Arnold said.

Arnold said the alleged victim is "going to be dealing with this for a long time."

Now that she has been identified, she will receive a victim notification every time one of the images turns up in an investigation, he said.

Tucker is being held without bond and is scheduled to be arraigned in federal court on Feb. 13. Her attorney could not be reached for comment.

Fox cuts ties to commentator Dick Morris

NEW YORK (AP) — Political commentator Dick Morris' prediction of a huge landslide for Mitt Romney didn't pan out. And now he's lost his job at Fox News Channel.

Network spokeswoman Dana Klinghoffer said Tuesday that Fox wasn't renewing its contract with Morris, who was steadfast throughout the campaign in his prediction of a big Romney win over President Barack Obama. He has made few appearances on Fox since the election.

Morris had also been criticized for accepting paid advertisements on his website from candidates that he discussed on the air at Fox.

On his website, Morris said he'll be appearing on CNN's Piers Morgan show Wednesday to talk politics.

Well: Getting Into Your Exercise Groove

Phys Ed

Gretchen Reynolds on the science of fitness.

This isn’t meant as an insult, but you are physiologically lazy. So am I. So are we all. Using treadmill testing, scientists have definitively established that, like other animals, humans naturally aim to use as little energy as possible during most movement. So when we walk or run, our bodies tend to choose a particular cadence, a combination of step length and step frequency, that allows us to move at any given speed with as little physiological effort as possible.

How we pick that cadence, though, and whether we can or would even want to change it has been unclear. But a series of recent studies involving runners, walkers, metronomes and virtual reality curtains suggests that while the tug of physiological laziness is strong, it can be controlled, or at least tweaked, with some conscious effort — and perhaps your iPhone playlist.

In the first and most revelatory of the studies, physiologists at Simon Fraser University in British Columbia asked adult volunteers to walk on a treadmill at an easy pace. Using motion capture technology, the scientists determined how many steps each person was taking per minute at this speed. A person’s pace depends, of course, on both step length and step frequency. But because the two are inextricably entwined — lengthen your stride and you’ll take fewer steps over a given distance — studying one provides sufficient information about the other, and frequency is easier to enumerate.

After establishing each volunteer’s preferred step frequency, the scientists then sped up or slowed the treadmill, and the researchers measured how quickly people’s legs responded.

The body, remember, wants things to be easy. When you increase or decrease the speed of your walking or running, various physiological changes occur; the amount of oxygen in your blood rises or falls, for instance, because your muscles start requiring more or less of the stuff. Other biochemical changes also occur within muscle cells. Sensing those changes, the body realizes that, at this new speed, your cadence isn’t ideal; you’re taking too few or too many steps to use the least possible amount of energy. Your body adjusts.

But that process takes a little while, at least five seconds or so for the oxygen levels to change and your body to recognize the alteration, says Max Donelan, a professor at Simon Fraser University who was a co-author of the study with his graduate student Mark Snaterse and others.

However, the walkers in the study were adjusting their step frequency within less than two seconds after the treadmill speed changed, Dr. Donelan points out. They then fine-tuned their pacing after that. But the first adjustment came almost instantly.

The same process occurred when the researchers repeated the experiment with runners. If the treadmill speed changed, the runners’ step frequency shifted almost immediately, too fast for internal physiology to have played much of a role.

These insty adjustments suggest that our brains very likely contain huge libraries of preset paces, Dr. Donelan and his colleagues have concluded, of idealized, “physiologically efficient” step cadences for any given speed and condition. It seems probable, in fact, that over our lifetimes, Dr. Donelan says, our brains develop and store countless templates for most pacing situations. We learn and remember what cadence allows us to use the least energy at that speed, and when we reach that speed, we immediately default to our body’s most efficient pace.

Just how the brain recognizes that we are moving at any particular speed is not completely understood, Dr. Donelan says, but almost surely involves messages from the eyes, feet, ears, nervous system, skin and other bodily systems.

Interestingly, it seems to be quite difficult to fool your brain. When Dr. Donelan and his colleagues draped shower-curtain-like enclosures around the front of a treadmill, projected a virtual reality scene of a hallway onto it and then manipulated people’s sense of the speed with which they were moving through the hallway, they found that people’s step frequency would quickly change to match this supposed new speed. But then they would settle back into their former cadence, even as the virtual hallway continued to move past them at unnatural speed.

Visual cues simply were not strong enough to affect pacing for long.

But the scientists have found one signal that does seem effectively to override the body’s strong pull toward its preferred ways of moving: a strongly rhythmic beat. When Dr. Donelan and his colleagues fitted runners or walkers with headphones tuned to a metronome, they found that they could increase or decrease volunteers’ step frequency, even if that frequency was faster or slower than a person’s preferred step pattern. They would also maintain that pace for as long as the metronomic rhythm continued unaltered. The volunteers aligned their movement to the beat.

In practical terms, this finding suggests that music may be one of the best ways to affect the pace of your running or walking, especially if you are trying to maintain a pace with which you are not familiar or which feels awkward. Want to start jogging faster than you have in the past? Load your iPod with uptempo music, Dr. Donelan suggests (although obviously ease into any changes in training slowly, to lessen the risk of injuries).

Dr. Donelan and his colleagues even have recently launched an iPhone app called Cruise Control that allows people to coordinate their pacing with their playlists. Input your preferred running or walking speed and the app skims your music library (nonjudgmentally; if you like Nickelback, that’s your business) and strings together songs with the requisite beat, even subtly altering the tempo of songs, if needed.

But of course, if you’re comfortable with your pace as it is, stick with it. For me, the most stirring message of these recent experiments is that, left to its own devices, your body will almost always obligingly try to choose the least demanding pace for you, a goal with which I’m happy to fall into step.
