Florida colleges fear boost in high-tech cheating

Florida's colleges are on high alert in the battle against what they fear is a growing number of tech-savvy cheaters.

Smartphones and social networking have made cheating easier and more widespread than ever, some say. And experts add that if schools don't crack down on the dishonesty now, there could be long-term consequences for society.

"Do you want to drive over a bridge designed by an engineer who cheated his way through school?" asked Jen Day Shaw, dean of students at the University of Florida. "Do you want to be operated on by a surgeon who cheats? If the students don't learn honesty and good values here, what are they going to do in the real world?"

Students will start final exams during the coming weeks, and the stakes can be huge. A poor grade in even one class may be enough to squash a student's chances to get into graduate school. For those already struggling, it can mean the difference between graduating and dropping out.

For some professors and students, cheating has turned into an arms race, where one is trying to outsmart the other. A professor makes the class put their cellphones in the front of the room; a student keeps a spare one in his pocket. A professor bans bathroom breaks during a test; a student claims it's a medical emergency. A professor uses a database of previously submitted term papers to catch plagiarism; a student pays someone to write an original paper.

"Students will challenge you on anything," said Angelia Millender, a vice president at Broward College, which tightened its academic honesty policy in 2010. "If a professor says put the phone away, they will say 'Where is that in writing?' Then they quote the policy in a way that serves them."

Educators say the biggest problem they encounter is plagiarism, with students copying and pasting someone else's work from the Internet. Often times, the students aren't intentionally trying to be dishonest but haven't been properly trained on how to cite their research, said Patricia Price, an associate professor of global and sociocultural studies at Florida International University.

Instructors also struggle to keep up with all the gadgets, apps, websites and social media sites that aid students in cheating. Most professors never thought to ban a student from wearing glasses during a test ? until Google recently announced plans to sell Internet powered "smart glasses."

"I know cheating has been going on forever," said Boris Bastidas, a senior at Florida Atlantic University. "But when you have the Internet in your pocket, it makes it a lot easier for students."

There are even YouTube videos showing students new creative ways to cheat, such as creating a fake label of a 20-ounce Coke bottle that replaces nutritional information with test answers and formulas.

"The things that get the hits on YouTube, you can believe at some point will be shared with faculty, too," said Ricardo Hall, dean of students at the University of Miami.

While colleges say technology has likely increased the number of cheating incidents, they don't have a clear picture of how big the problem is. UF had 385 honor code violations last school year, an 18 percent increase from the previous year. But officials say that could mean that educators are getting better at catching cheaters. FIU says the number of cases has been flat, while an FAU official says the university doesn't have a central tracking system.

And of course, many cheaters never get caught.

"So much of the information is anecdotal," said Ed Pratt, dean of undergraduate students at FAU. "You talk to students and faculty, you know cheating takes place, but it's really difficult to get a handle on how many students are doing it."

There have been several high-profile cases in the state, including a business class at the University of Central Florida where many students received advance test copies in 2010, and a scandal at Florida State University in 2007 involving student athletes cheating on an Internet test.

The ease of cheating, as well as the consequences, vary by instructor, students say.

"Some professors are really strict, and others kind of have the attitude that if you cheat, you're not learning, and that's not my problem," Bastidas said.

Price takes many precautions to prevent the problem, "but if a student is determined to cheat, they'll probably find a way," she said.

Improve The Value Of Your Home By Remodeling Your Bathroom ...

When looking to improve the value of your home, remodeling a bathroom can be a great step to take. Simple bathroom remodeling steps can include painting, changing out fixtures and installing new tiles. More elaborate efforts can include replacing bathtubs, toilets and sinks. Whatever route you choose, you?re sure to see an increased home value when you update your bathroom.

Give your bathroom a unique touch by deciding on a theme. Most people spend hours in their bathrooms, but apart from the coordinated colors, nothing seems to be unique. Come up with fun themes like pirate, under the sea, at the beach, or shipwrecked. Finding accessories for your idea can be fun and give your bathroom a sense of personality.

If you are redoing your tile floors, look into radiant heat tiles. These tiles provide heat through your electricity and are a real show stopper. Luckily, they are also easy to install yourself if you can follow the directions. This makes it a project you can add on whether you are hiring someone or doing it yourself. You?ll be grateful you did the first winter morning that you walk into your bathroom.

When improving your house, there are some projects that you can do yourself and others that you cannot. If you feel like you can complete a simple task like repainting the kitchen, then by all means do it, in order to save yourself some extra money. Just be sure that you know what you?re getting yourself into before you start a project. You don?t want to try and remodel your bathroom and find out half way through that you?re not sure if you can complete the task without hitting a pipeline.

If you are interested in changing the look of your bathroom, this space could be the perfect choice for your next home improvement project. Give your bathroom an extra special touch by installing radiant floor heat and a light-tube, which gives the space the appearance of having natural light. Both features come with instructions that are easy to follow.

Is it cheaper to do it yourself or pay someone else? If you decide to completely re-do your bathroom, but know nothing about plumbing, it might be beneficial to pay a plumber to come in. Also, you can check out the self help books at your local building supply. Don?t be afraid to ask. A simple project shouldn?t cost more because of inexperience.

Utah: Medical records breach more extensive

SALT LAKE CITY (AP) ? Health officials in Utah say hackers who downloaded thousands of medical files from state computers stole far more personal information than originally thought.

The Utah Department of Health said Friday that nearly 182,000 recipients of Medicaid and the Children's Health Insurance Program had their personal information stolen. The department estimates more than 25,000 Social Security numbers were compromised.

Agency officials originally thought the hackers stole 24,000 Medicaid claims. But officials now say 24,000 files were stolen, and each file potentially contains information on hundreds of people.

Officials say the attack started last week and likely came from eastern Europe. The information was on a new server that had security tools installed improperly.

The agency says it plans to reach out to those affected and offer free credit monitoring services for one year.

Serena routs Stosur, reaches Family Circle finals

CHARLESTON, S.C. (AP) ? Serena Williams even impressed herself with her powerful showing at the Family Circle Cup on Saturday.

Williams needed less than an hour to dispatch second-seeded Samantha Stosur, 6-1, 6-1 and advance to the clay-court final.

"You know, I think it was just one of those days that I could have done anything against anybody," Williams said.

There aren't many people in the world who could've withstood Williams' performance at the Family Circle Tennis Center. The 10th-ranked player was on her game from the start, winning the match's first eight points and rarely letting Stosur catch a breath.

On Sunday, Williams will face Lucie Safarova, a 6-0, 6-0 winner over Polona Hercog, for the championship.

Stosur held serve to cut Williams' lead to 2-1, then lost the next nine games. Stosur, who defeated Williams to win the U.S. Open title last September, got a loud cheer from the crowd when she prevented Williams from shutting her out in the second set.

Williams hit a forehand winner to end the match moments later, and eliminated Stosur from a tournament for the second straight week. Williams beat Stosur 7-5, 6-3 last week at the Sony Ericsson Open, serving 20 aces in the hard-court win.

Williams only had seven aces in this one, but was in command of nearly every shot she hit.

"I have to say this is probably the best match I've played in my career, either in a long time or it's up there in the top five," Williams said.

Stosur is a skilled 28-year-old player ranked fifth and rising. She combines a powerful serve with the fitness to chase down about any shot. Stosur rallied on Friday to defeat Serena's older sister, Venus, and was seeking to become just the eighth player to beat both Williams sisters in the same tournament.

Serena quickly made sure that didn't happen.

She cracked serves over 100 mph, landed returns in both corners and frustrated Stosur at every turn.

Stosur moved up on Williams' serve, varied her own serves ? anything to slow down Williams' relentless march. Stosur hoped to regroup in the second set, yet Williams' powerful serves and ground strokes kept coming.

Already down 30-love in the second set's opening game, Williams sent a rocket shot into the right corner. Stosur tried to chase, realized she couldn't and slowed her movement, looking to the sky in frustration.

"She was way too good today," Stosur said. "I think she was pretty happy with the way she played."

Who wouldn't be?

The hole in Williams' Hall-of-Fame resume is clearly on clay. She owns 13 Grand Slam titles, but just one coming at the French Open. Williams defeated sister Venus in 2002 for the championship at Roland Garros. Serena reached the semifinals there the next year and has not made it past the quarterfinals in five appearances since.

Williams has gotten only one day's practice on clay since the Sony Ericsson event ended. Still, she believes she's sliding better than she has in recent years and excited about her prospects on the surface this year.

The Family Circle Cup is a good start to her season on clay, she said. But that's all it is, a start.

"I'm trying to play like this at the end of the clay-court season," she said. "So we'll see."

Her made only mistake in the match, at least in her eyes ? a full-blown 360-degree, pirouette after a winning forehand that had her laughing as she moved ahead 2-0 in the second set.

"I didn't mean to spin," Williams said. "I was on clay and I kept spinning and I was like, 'God, this is so embarrassing right now. I hope nobody remembers this.'"

They'll remember just about every Williams did in this one, that's for sure.

Antibiotics a safe and viable alternative to surgery for uncomplicated appendicitis, say experts

Antibiotics a safe and viable alternative to surgery for uncomplicated appendicitis, say experts

Friday, April 6, 2012

Giving antibiotics to patients with acute uncomplicated appendicitis is a safe and viable alternative to surgery, say experts in a study published on bmj.com today.

Surgery to remove an inflamed appendix (appendicectomy) has been the mainstay of treatment for acute appendicitis since 1889 and the general assumption is that, without surgery, the risk of complications, such as perforation or infection, is high.

However, recent studies have reported fewer problems with antibiotic therapy than surgery in patients with uncomplicated appendicitis, but results have been inconclusive.

So a team of researchers at the Nottingham Digestive Diseaeses Centre NIHR Biomedical Research Unit set out to compare the safety and efficacy of antibiotic therapy as an initial treatment for uncomplicated acute appendicitis.

They analysed the results of four randomised controlled trials involving 900 adult patients diagnosed with uncomplicated acute appendicitis. A total of 470 patients received antibiotics and 430 underwent surgery.

Differences in study design and quality were taken into account to minimise bias.

Antibiotic therapy was associated with a 63% success rate at one year and a 31% relative reduction in complications compared with surgery.

Even after excluding patients from one study who crossed over from the antibiotic group to the surgery group, a significant (39%) reduction in complications with antibiotic therapy compared with surgery remained.

Of 68 patients treated with antibiotics who were readmitted with recurrence of symptoms, four had normal appendix and 13 had complicated appendicitis. Three patients were treated successfully with another course of antibiotics.

There were no significant differences in either length of hospital stay or risk of developing complicated appendicitis between the two groups of patients.

The authors argue that the role of antibiotics in acute uncomplicated appendicitis "has been overlooked based mainly on tradition rather than evidence" and they suggest that a careful 'wait, watch and treat' policy may be adopted in patients considered to have uncomplicated appendicitis or in whom the diagnosis is uncertain.

However, they stress that for those with clear signs of perforation or peritonitis (inflammation of the abdominal wall) ? early appendicectomy still remains the 'gold standard.'

They conclude that antibiotic therapy "is a safe initial therapy for patients with uncomplicated acute appendicitis" and that it "merits consideration as a primary treatment option for early uncomplicated appendicitis."

In an accompanying editorial, Dr Olaf Bakker from the Department of Surgery at the University Medical Center Utrecht in the Netherlands argues that treating appendicitis conservatively has "major certain disadvantages" as the reoccurrence rate of appendicitis is up to 20% in the first year. He argues that until more convincing and longer term results are published, "appendectomy for uncomplicated appendicitis will probably continue."

Samsung expects to double Q1 profit versus last year, sends itself a love note

Samsung Q1 2012 earnings guidance
Sammy has issued guidance for its financial performance between January and March 2012, ahead of a fuller earnings report due later this month. In contrast to HTC's latest news, the Korean giant looks rosy enough -- it's predicting an operating profit of 5.8 trillion won ($5 billion), which is almost double the quarterly profit from last year. Overall revenues continued to grow steadily too, rising nearly 22 percent to 45 trillion won ($40 billion). We'll need to wait for more detail to see where the growth is coming from, but it'd be cheesily nice to think our affection for the Galaxy Note had something to do with it.
