Feds rooting out 'unwelcome speech' on campus: But what is that?

The failure of the University of Montana to respond adequately to rape and sexual assault allegations against popular football players has led to a broadening of how the federal government defines sexual harassment, causing free speech advocates to worry that the new policy will be used to punish ?unwelcome? flirting and chill the right to speak freely on campus.

A detailed ?resolution agreement? with the University of Montana, dated May 9, outlines what the US Department of Education and Justice Department describe as a new ?blueprint? for how colleges should view sex discrimination, assault, and harassment on campuses. The new policy is seen as binding, because colleges can lose federal funding, including Stafford and Pell grants, if they don?t abide.

Key among the federal findings at the University of Montana, where the university acknowledged it failed to properly address allegations of sexual assault against several football players, is the necessity to broaden the definition of sexual harassment to ?unwelcome conduct of a sexual nature,? including ?verbal conduct,? or speech.

RECOMMENDED: The evolution of sexual harassment awareness

The new policy also suggests that harassment does not have to be ?objectively offensive? to warrant complaints, and demands colleges take action against alleged aggressors even before judicial hearings are held.

A ?culture of rape and sexual violence ? is not exclusive to our campus,? Brittany Salley-Rains, co-director of the Women?s Resource Center at the University of Montana, told reporters at a press conference. ?There needs to be more prevention going forward and the university administration needs to do more to bring attention to the detrimental culture that threatens women."

The new policy outlined in the University of Montana agreement comes in response to campus expos?s about lax enforcement of sexual harassment rules, the signing by President Obama in March of the Campus Sexual Violence Elimination Act to make it easier to report sex crimes on campus, and a series of probes by the Department of Education into major universities that have allegedly failed to properly address sexual harassment and assault allegations.

To be sure, the new rules still require that sex crime allegations suggest either pervasive or severe acts or language, and still require an objective standard before allegations are upheld, according to the Department of Education?s letter to the University of Montana.

But campus free speech advocates have balked at those explanations, saying the policy could have a chilling impact on social, professional, even political dynamics on US college campuses. Critics say any sexual topic, including flirtation, sex ed classes, or a discussion of Vladimir Nabokov?s ?Lolita,? could be deemed ?unwelcome? and the basis for censure.

Such fears aren?t theoretical, campus free speech advocates say, citing a professor at the University of Denver who was found to have sexually harassed students by talking about sexual taboos in American culture.

?Unwelcome? speech has also been used in allegations of teachers creating a ?hostile environment,? which apparently happened to a professor at Purdue University at Calumet who last year faced investigation for criticizing on Facebook the failure by moderate Muslims to condemn violence by Islamic extremists.

The new federal rule ?is part of a decades-long effort by anti-?hate speech? professors, students, activists and administrators to classify any offensive speech as harassment unprotected by the First Amendment,? writes Greg Lukianoff, author of ?Unlearning Liberty: Campus Censorship and the End of American Debate,? in the Wall Street Journal. ?Such speech codes reached their height in the 1980s and 1990s, but they were defeated in federal and state court and came in for public ridicule. Despite these setbacks, harassment-based speech codes have become the de facto rule.?

The new sexual harassment blueprint, however, is necessary to force colleges to deal with a serious and pervasive problem that continues to seriously violate women?s civil rights, federal officials and civil rights groups maintain.

A recent investigative report by the Center for Public Integrity found that ?students deemed ?responsible? for alleged sexual assaults on college campuses can face little or no consequence for their acts.?

?Yet their victims? lives are frequently turned upside down,? the report asserts. ?For them, the trauma of assault can be compounded by a lack of institutional support, and even disciplinary action. Many times, victims drop out of school, while their alleged attackers graduate.?

The Department of Education probe of the University of Montana?s handling of rape allegations against football players found problems with both the university?s sex harassment policy and its implementation. Federal officials focused on police reports, for example, that suggested that one alleged victim simply ?regretted sex? and that another one didn?t seem sufficiently upset, and smelled of alcohol.

Seth Galanter, acting assistant secretary for civil rights with the Education Department, said the evidence showed sex harassment at the college violated civil rights law because the acts interfered with the ability of women to benefit from school programs.

"What is noteworthy about this announcement today is not the problems our investigation found at the university, but a shared commitment to the equality of women students and their safety," Roy Austin, deputy assistant attorney general for the Justice Department's civil rights division, said in a statement.

The broadened definition of sexual harassment enters the public debate two years after the Department of Education?s civil rights office and the Department of Justice tweaked sexual assault policy by lowering the evidentiary requirements for determinations of guilt. Instead of victims having to lay out ?clear and convincing evidence? of assault or harassment, a ?preponderance of evidence? is all that?s now necessary to determine that sexual assault or harassment took place.

Moreover, what?s troubling to some critics is that the idea of subjectively silencing ?unwelcome speech? about sex may seep into other corners of campus life, even going so far as to poison debates about personal ideology and politics.

?I doubt [the new sexual harassment policy] is intended to be fairly enforced,? writes civil libertarian Wendy Kaminer on Atlantic.com. ?I doubt federal officials want or expect it to be used against sex educators, advocates of reproductive choice, anti-porn feminists, or gay rights advocates, if their speech of a sexual nature is ?unwelcome? by religious conservatives.?

?When people demand censorship of ?unwelcome? speech, they?re usually demanding censorship of speech that they find unwelcome,? Ms. Kaminer writes. ?They usually seek to silence their political or ideological opponents, not their friends ? all in the name of some greater good.?

Individuals who drink heavily and smoke may show 'early aging' of the brain

May 18, 2013 ? Treatment for alcohol use disorders works best if the patient actively understands and incorporates the interventions provided in the clinic. Multiple factors can influence both the type and degree of neurocognitive abnormalities found during early abstinence, including chronic cigarette smoking and increasing age. A new study is the first to look at the interactive effects of smoking status and age on neurocognition in treatment-seeking alcohol dependent (AD) individuals. Findings show that AD individuals who currently smoke show more problems with memory, ability to think quickly and efficiently, and problem-solving skills than those who don't smoke, effects which seem to become exacerbated with age.

Results will be published in the October 2013 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.

"Several factors -- nutrition, exercise, comorbid medical conditions such as hypertension and diabetes, psychiatric conditions such as depressive disorders and post-traumatic stress disorder, and genetic predispositions -- may also influence cognitive functioning during early abstinence," explained Timothy C. Durazzo, assistant professor in the department of radiology and biomedical imaging at the University of California San Francisco, and corresponding author for the study. "We focused on the effects of chronic cigarette smoking and increasing age on cognition because previous research suggested that each has independent, adverse affects on multiple aspects of cognition and brain biology in people with and without alcohol use disorders. This previous research also indicated that the adverse effects of smoking on the brain accumulate over time. Therefore, we predicted that AD, active chronic smokers would show the greatest decline in cognitive abilities with increasing age."

"The independent and interactive effects of smoking and other drug use on cognitive functioning among individuals with AD are largely unknown," added Alecia Dager, associate research scientist in the department of psychiatry at Yale University. "This is problematic because many heavy drinkers also smoke. Furthermore, in treatment programs for alcoholism, the issue of smoking may be largely ignored. This study provides evidence of greater cognitive difficulties in alcoholics who also smoke, which could offer important insights for treatment programs. First, individuals with AD who also smoke may have more difficulty remembering, integrating, and implementing treatment strategies. Second, there are clear benefits for thinking skills as a result of quitting both substances."

Durazzo and his colleagues compared the neurocognitive functioning of four groups of participants, all between the ages of 26 and 71 years of age: never-smoking healthy individuals or "controls" (n=39); and one-month abstinent, treatment-seeking AD individuals, who were never-smokers (n = 30), former-smokers (n = 21) and active-smokers (n = 68). Evaluated cognitive abilities included cognitive efficiency, executive functions, fine motor skills, general intelligence, learning and memory, processing speed, visuospatial functions, and working memory.

"We found that, at one month of abstinence, actively smoking AD [individuals] had greater-than-normal age effects on measures of learning, memory, processing speed, reasoning and problem-solving, and fine motor skills," said Durazzo. "AD never-smokers and former-smokers showed equivalent changes on all measures with increasing age as the never-smoking controls. These results indicate the combination of alcohol dependence and active chronic smoking was related to an abnormal decline in multiple cognitive functions with increasing age."

"These results indicate the combined effects of these drugs are especially harmful and become even more apparent in older age," said Dager. "In general, people show cognitive decline in older age. However, it seems that years of combined alcohol and cigarette use exacerbate this process, contributing to an even greater decline in thinking skills in later years."

Durazzo agreed. "Chronic cigarette smoking, excessive alcohol consumption, and increasing age are all associated with increased oxidative damage to brain tissue," he said. "Oxidative damage results from increased levels of free radicals and other compounds that directly injure neurons and other cells that make up the brain. Cigarette smoking and excessive alcohol consumption expose the brain to a tremendous amount of free radicals. We hypothesize that chronic, long-term exposure to cigarette smoke and excessive alcohol consumption interacts with the normal aging process to produce greater neurocognitive decline in the active-smoking AD group."

Cigarette smoking is a "modifiable health risk" that is directly associated with at least 440,000 deaths every year in the United States, Durazzo noted. "Chronic smoking, and to a lesser extent, alcohol use disorders are also associated with an increased risk for Alzheimer's disease," he said. "So, the combination of these modifiable health risks may place an individual at even greater risk for development of Alzheimer's disease. Given the above, in conjunction with the findings from our cognitive and neuroimaging research, we completely support programs that routinely offer smoking cessation programs to all individuals seeking treatment for alcohol/substance abuse disorders."

Cannes opens with DiCaprio, Spielberg

CANNES, France (AP) ? The Cannes Film Festival is getting under way with a blockbuster day of Steven Spielberg and Baz Luhrmann's "The Great Gatsby."

The French Riviera extravaganza began on a rainy Wednesday, where the prestigious festival was to open with the 3-D adaptation of F. Scott Fitzgerald's novel. Spielberg is serving as jury president of this year's Cannes, presiding over a particularly starry group including Nicole Kidman, Ang Lee and Christoph Waltz.

"Gatsby" is making its European premiere Wednesday night, nearly a week after opening in North America. Such timing is atypical for Cannes, but the glamorous, flashy film is otherwise perfectly in line with the glitzy festival. It also returns Leonardo DiCaprio to Cannes' famous red carpet.

(AP) ? Congressional Republicans and Democrats on Wednesday challenged Attorney General Eric Holder over the Justice Department's handling of the investigation of national security leaks and its failure to talk to The Associated Press before issuing subpoenas for the news service's telephone records.

In exchanges that often turned testy, Holder defended the inquiry while pointing out that he had removed himself from any decision on subpoenas. The attorney general explained that he had been interviewed about what he knew of national security developments that prompted the probe.

The investigation follows congressional demands into whether Obama administration officials leaked secret information to the media last year to enhance the president's national security credentials in an election year.

"It's an ongoing matter and an ongoing matter in which I know nothing," Holder told the House Judiciary Committee.

The Justice Department secretly obtained two months of telephone records of reporters and editors for the AP, seizing the records for more than 20 separate telephone lines assigned to the AP and its journalists in April and May 2012.

Holder defended the move to collect AP phone records in an effort to hunt down the sources of information for a May 7, 2012, AP story that disclosed details of a CIA operation in Yemen to stop an airliner bombing plot around the anniversary of the killing of terrorist leader Osama bin Laden.

The attorney general called the story the result of "a very serious leak, a very grave leak." Earlier this week in a statement, AP President and Chief Executive Officer Gary Pruitt called the gathering of phone records a "massive and unprecedented intrusion" into how news organizations gather the news.

Under questioning, Holder said he recused himself from the investigation though he couldn't provide the panel with the exact date nor did he do so formally in writing. He said he was unable to answer questions on the subpoenas and why the Justice Department failed to negotiate with the AP prior to the subpoenas, a standard practice.

"The telephone records would not disappear if the AP had been notified," said Rep. Zoe Lofgren, D-Calif. "How could it ever be the case?"

The frustration extended to Republicans and Democrats.

"There doesn't appear to be any acceptance of responsibility for things that have gone wrong," Rep. James Sensenbrenner, R-Wis., told Holder. He suggested that administration officials travel to the Harry S. Truman Presidential Library and take a photo of the famous sign, "The buck stops here."

It was the Justice Department's No. 2 official, Deputy Attorney General James Cole, who made the decision to seek news media phone records, Holder said.

Last year, Holder appointed two U.S. attorneys to lead a Justice inquiry into who leaked information about U.S. involvement in cyber-attacks on Iran and an al-Qaida plot to place an explosive device aboard a U.S.-bound flight. Holder had resisted calls for a special counsel, telling lawmakers that the two attorneys, Ron Machen and Rod Rosenstein, are experienced, independent and thorough.

Holder was grilled on several scandals rocking the administration, including the targeting of conservative groups by the Internal Revenue Service and any missteps in sharing intelligence information prior to the bombings in Boston.

Holder said the FBI's criminal investigation of the Internal Revenue Service could include potential civil rights violations, false statements and potential violations of the Hatch Act, which prohibits federal employees from engaging in some partisan political activities.

In one of the sharpest exchanges, Holder defended Thomas Perez's tenure as head of the Justice Department's Civil Rights Division and said he would make a great secretary of the Labor Department.

Rep. Darrell Issa, R-Calif., was critical of Perez and repeatedly pressed Holder, who at one point refused to stop talking and accused Issa of repeatedly mischaracterizing the work of the Justice Department.

"That is inappropriate and is too consistent with the way in which you conduct yourself as a member of Congress. It's unacceptable and it's shameful," Holder told Issa.

The congressman ignored the comments and continued to question Holder.

Responding to news of the gathering of AP records, Sen. Chuck Schumer, D-N.Y., planned to revive a 2009 media shield bill that protects journalists and their employers from having to reveal information, including the identity of sources who had been promised confidentiality.

The bill does contain some exceptions in instances of national security.

"This kind of law would balance national security needs against the public's right to the free flow of information," Schumer said in a statement. "At minimum, our bill would have ensured a fairer, more deliberate process in this case."

The White House threw its support behind the push Wednesday morning, with Ed Pagano, President Barack Obama's liaison to the Senate, placing a call to Schumer's office to ask him to revive the bill ? a step the senator had planned to take. White House spokesman Jay Carney said Obama "believes strongly we need to provide the protection to the media that this legislation would do."

Obama's support for the bill signaled an effort by the White House to show action in the face of heated criticism from lawmakers from both parties and news organizations about his commitment to protecting civil liberties and freedom of the press.

White House officials have said they are unable to comment publicly on the incident at the heart of the controversy because the Justice Department's leak probe essentially amounts to a criminal investigation of administration officials.

It's not clear whether such a law would have prevented the government from gathering the AP phone records as it would depend on the provisions in the bill and how they were written.

Sen. Dianne Feinstein, D-Calif., chairwoman of the Senate Intelligence committee, said Wednesday that the leak was "within the most serious leaks because it definitely endangered some lives."

Feinstein said it was her understanding that the information gathering did not focus on the "content of phone calls," but rather "to see who reporters have spoken to, that somebody did provide this information with respect to this bomb."

On Wednesday, the leaders of the news organization whose members cover Congress told Cole that "your agency has not provided adequate reason for this disconcerting action."

"We are concerned the incursions by the Justice Department in this case jeopardize the relationship between reporters and anonymous sources, decreasing the likelihood that people will come forward with vital information of public importance," the representatives of the Congressional press galleries said in a letter.

"The press must be secure in its ability to conduct its business," the letter stated. "This critical work of reporters is protected by the First Amendment. Please explain how this unparalleled use of your investigative power is constitutionally consistent."

SEE IT: Pacers coach and his Stupid Human Trick

Indiana Pacers Coach Frank Vogel On David Letterman Show / 1986

nbaus3030 via YouTube

Indiana Pacers coach Frank Vogel appears on 'Late Night with David Letterman' back in 1986.

Most people know Frank Vogel as the head coach of the Indiana Pacers.

But it turns out the New Jersey native was something of a child prodigy when it comes to the odd combination of spinning a basketball and brushing his teeth.

Vogel, whose Pacers are tied up at a game apiece with the Knicks in the Eastern Conference semifinals, showcased his unique skill as an 8th grader for David Letterman as part of the Late Night host's classic 'Stupid Human Tricks' routine back in 1986.

In the clip, Vogel takes the stage and spins a basketball on the end of a tooth brush. Then the future NBA coach proceeds to brush his teeth with the ball still spinning. The original spin brush!

It's a cool stunt that earns a "you're gonna knock every tooth out of your head doing this" from the laughing Letterman.

Not only did Vogel survive the stunt with a full set of choppers, but he successfully repeated the feat last year for a group of Indianapolis kids.

Now the third-year NBA head coach will try to pull off his best trick yet ... leading the underdog Pacers into the Eastern Conference finals. Game 3 against the Knicks is Saturday.

Dust in the clouds: Cirrus clouds form around mineral dust and metallic particles

May 9, 2013 ? At any given time, cirrus clouds -- the thin wisps of vapor that trail across the sky -- cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 miles above the Earth's surface.

Cirrus clouds influence global climate, cooling the planet by reflecting incoming solar radiation and warming it by trapping outgoing heat. Understanding the mechanisms by which these clouds form may help scientists better predict future climate patterns.

Now an interdisciplinary team from MIT, the National Oceanic and Atmospheric Administration (NOAA), and elsewhere has identified the major seeds on which cirrus clouds form. The team sampled cirrus clouds using instruments aboard high-altitude research aircraft, analyzing particles collected during multiple flights over a nine-year period. They found that the majority of cloud particles freeze, or nucleate, around two types of seeds: mineral dust and metallic aerosols.

The absence of certain particles in the clouds also proved interesting. While scientists have observed that substances like black carbon and fungal spores readily form cloud particles in the lab, the team detected barely a trace of these particles in the upper atmosphere.

"We think we're really looking at the seed, the nucleus of these ice crystals," says Dan Cziczo, an associate professor of atmospheric chemistry at MIT. "These results are going to allow us to better understand the climatic implications of these clouds in the future."

Cziczo and his colleagues have published their results this week in Science.

Up in the air

Cirrus clouds typically form at altitudes higher than most commercial planes fly. To sample at such heights, the team enlisted three high-altitude research aircraft from NASA and the National Science Foundation (NSF): a B-57 bomber, a DC-8 passenger jet, and a G-V business jet, all of which were repurposed to carry scientific instruments.

From 2002 to 2011, the team conducted four flight missions in regions of North America and Central America where cirrus clouds often form. Before takeoff, the team received weather forecasts, including information on where and when clouds might be found.

"More often than not, the forecast is solid, and it's up to the pilot to hit a cloud," Cziczo says. "If they find a good spot, they can call back on a satellite phone and tell us if they're inside a cloud, and how thick it is."

For each mission, Cziczo and Karl Froyd, of NOAA's Earth System Resource Laboratory, mounted one or two instruments to the nose of each plane: a single particle mass spectrometer and a particle collector.

Each flight followed essentially the same protocol: As a plane flew through a cloud, ice particles flowed through a specialized inlet into the nose of the plane. As they flowed in, the particles thawed, evaporating most of the surrounding ice. What's left was a tiny kernel, or seed, which was then analyzed in real time by the onboard mass spectrometer for size and composition. The particle collector stored the seeds for further analysis in the lab.

A human effect on cloud formation

After each flight, Cziczo and his colleagues analyzed the collected particles in the lab using high-resolution electron microscopy. They compared their results with analyses from the onboard mass spectrometer and found the two datasets revealed very similar cloud profiles: More than 60 percent of cloud particles consisted of mineral dust blown into the atmosphere, as well as metallic aerosols.

Cziczo notes that while mineral dust is generally regarded as a natural substance originating from dry or barren regions of the Earth, agriculture, transportation and industrial processes also release dust into the atmosphere.

"Mineral dust is changing because of human activities," Cziczo says. "You may think of dust as a natural particle, but some percentage of it is manmade, and it really points to a human ability to change these clouds."

He adds that some global-modeling studies predict higher dust concentrations in the future due to desertification, land-use change and changing rainfall patterns due to human-induced climate effects.

Cziczo's team also identified a "menagerie of metal compounds," including lead, zinc and copper, that may point to a further human effect on cloud formation. "These things are very strange metal particles that are almost certainly from industrial activities, such as smelting and open-pit burning of electronics," Cziczo adds. Lead is also emitted in the exhaust of small planes.

Contrary to what many lab experiments have found, the team observed very little evidence of biological particles, such as bacteria or fungi, or black carbon emitted from automobiles and smokestacks. Froyd says knowing what particles are absent in clouds is just as important as knowing what's present: Such information, he says, can be crucial in developing accurate models for climate change.

"There's been a lot of research efforts spent on looking at how these particle types freeze under various conditions," Froyd says. "Our message is that you can ignore those, and can instead look at mineral dust as the dominant driving force for the formation of this type of cloud."

The group's experimental approach was an impressive feat in itself, says Brian Toon, a professor of atmospheric and oceanic sciences at the University of Colorado. In a typical cirrus cloud, only one particle in 100,000 forms an ice crystal, making the odds of capturing such crystals slim at best.

"This group has used an instrument in a plane flying at speeds of two football fields per second to catch individual ice crystals, evaporate them and measure the composition of the tiny remnant particles -- an amazing technological achievement," says Toon, who was not involved in the research. "Now these measurements need to be repeated over a wide range of locations to be sure they are general."

This research was funded by NASA and the NSF.

Pilot insurance program for students playing contact sports passes ...

In this Jan. 22, 1983, file photo, Dallas Cowboys Tony Dorsett takes a hard hit and fumbles the ball in first quarter of a game against the Washington Redskins. Dorsett is one of at least 300 former players suing the NFL claiming it pressured them to play with concussions and other injuries and then failed to help them pay for health care in retirement to deal with those injuries. (AP/File)

A bill that began as a limit on the amount of full-contact practices for high school and middle school football teams has morphed into a pilot insurance program designed to help cover students at risk of concussions during sports practice.

The bill passed the Texas House on Tuesday on a voice vote.

The legislation by Rep. Eddie Lucio III, D-Brownsville, would let the UIL and the Texas Education Agency develop an option insurance program that would cover ongoing, post-season, concussion-related injuries incurred by boys who play football and girls who play soccer for UIL. The program would be option, not a mandate.

The bill would need to make it through the budget conference committee, but passage of it would allow them to discuss it.

Lucio is currently laying out his bill, and it looks to have support.

?If you get a concussion, it doesn?t manifest itself right away. Sometimes it manifests itself after the season is over. The current insurance program (offered by the public schools) won?t cover you if you start to suffer from concussion-related injury after the season,? Lucio said. ?As you know, we have a very serious problem when it comes to head trauma and mental health of people who play contact sports. This would allow parents to properly prepare and guard against that.?

The bill would create a pilot program for insurance coverage. UIL and TEA would choose the participating school districts, which could opt out if they are tapped. It is also permissive to the parents, who can choose to pay the $5 coverage cost or not.

The bill has already been added to the budget bill, as it carries a cost of $100,000 to administer it. That Article 11 rider can?t be considered in conference committee without Lucio?s new legislation, according to House Appropriations Chairman Jim Pitts, who supported the new bill.

Stakeholders are in support, including coaches and teachers, Lucio said.

Lucio pulled down his original bill, he said, when he learned that the UIL was going to take up the same issue next month.?As introduced, Lucio?s bill would have limited to one hour per week the full-contact practices for high school and middle school football teams.

Next month, the UIL Legislative Council will take up the unanimous recommendation of its Medical Advisory Committee that football programs be limited to 90 minutes of full-contact, game-speed practices per player per week during the regular season and playoffs.

Liz Ryan: How do I bring up relocation expense on my job interview?

Dear Liz,

I have a second interview for a Director job next week, and at the first
interview I didn't say a word about relocation. I had just finished up a
one-year international assignment and so I assume the hiring manager knows I'm
going to need relocation assistance. That's why I didn't bring it up. I am
staying with friends now. How and when do I bring up the overhanging issue of my
relocation expenses when I go to the second interview next week?

Thanks,

Grace

Dear Grace,

Congratulations on the interview! You were correct not to bring up relocation at
a first interview. I don't recommend that you talk about compensation or any of
the transactional issues on a first interview, because at that early stage you
haven't established that there's even a mutual interest. Now you know - they
want you to come back. Now it's time to talk about what it would take to get you
on their team, including the relocation package.

Your interview is already set up, so you can talk about compensation there. We
usually recommend that you bring up salary with the person who contacts you to
set up the second interview.

When you're talking with your hiring manager at the interview, you can ask
"Would this be a good time for us to synch up on the comp package? I'd hate to
waste your time if we're not in the same ballpark." Of course, you'd hate to
waste your own time too, but we'll be polite and make it all about him or her,
your hiring manager.

Undoubtedly your hiring manager will ask you "Well, what would it take to get
you here, if we go in that direction?" You can say "I'm looking at opportunities
in the range of whatever to whatever." There's no sense talking about extras
like your relo package if your basic comp level is going to make the guy's head
explode. If the salary or salary-plus-bonus part, the cash compensation, goes
well, you can say "And of course I need to get out here." Let that phrase sit
there. You don't need to go into detail. Companies of any size have relo
policies.

If they balk at the idea of bringing you to town for an out-of-town job, run
away fast. For a Director level position, that piece of the package should go
without saying.

That being said, a friend of mine once got an offer for a VP job in Maine, and
the CEO told her that he wouldn't pay for temporary lodging. He said "We'll fly
you up one weekend and you can get an apartment, and we'll pay the commission on
your house sale in Chicago. After that you're on your own." My friend fled, of
course. The cheapskate CEO's relo offer made no sense at all. She's selling a
house, and she's supposed to find an apartment in one weekend and use it as
temporary lodging? And sign a one-year lease on the apartment? The nice name for
folks like that CEO is "penny-wise and pound foolish."

You are in great shape, Grace. If they don't get that people have to physically
move and move their belongings in order to take out-of-town jobs, they don't
deserve you. Keep us posted!

Best,

Liz

Unusual comparison nets new sleep loss marker

May 3, 2013 ? For years, Paul Shaw, PhD, a researcher at Washington University School of Medicine in St. Louis, has used what he learns in fruit flies to look for markers of sleep loss in humans.

Shaw reverses the process in a new paper, taking what he finds in humans back to the flies and gaining new insight into humans as a result: identification of a human gene that is more active after sleep deprivation.

"I'm calling the approach cross-translational research," says Shaw, associate professor of neurobiology. "Normally we go from model to human, but there's no reason why we can't take our studies from human to model and back again."

Shaw and his colleagues plan to use the information they are gaining to create a panel of tests for sleep loss. The tests may one day help assess a person's risk of falling asleep at the wheel of a car or in other dangerous contexts.

PLOS One published the results on April 24.

Scientists have known for years that sleep disorders and disruption raise blood serum levels of interleukin 6, an inflammatory immune compound. Shaw showed that this change is also detectable in saliva samples from sleep-deprived rats and humans.

Based on this link, Shaw tested the activity of other immune proteins in humans to see if any changed after sleep loss. The scientists took saliva samples from research participants after they had a normal night's sleep and after they stayed awake for 30 hours. They found two immune genes whose activity levels rose during sleep deprivation.

"Normally we would do additional human experiments to verify these links," Shaw says. "But those studies can be quite expensive, so we thought we'd test the connections in flies first."

The researchers identified genes in the fruit fly that were equivalent to the human genes, but their activity didn't increase when flies lost sleep. When they screened other, similar fruit fly genes, though, the scientists found one that did.

"We've seen this kind of switch happen before as we compared families of fly genes and families of human genes," Shaw says. "Sometimes the gene performing a particular role will change, but the task will still be handled by a gene in the same family."

When the scientists looked for the human version of the newly identified fly marker for sleep deprivation, they found ITGA5 and realized it hadn't been among the human immune genes they screened at the start of the study. Testing ITGA5 activity in the saliva samples revealed that its activity levels increased during sleep deprivation.

"We will need more time to figure out how useful this particular marker will be for detecting sleep deprivation in humans," Shaw says. "In the meantime, we're going to continue jumping between our flies and humans to maximize our insights."

Dr. Drew checks out of 'Celebrity Rehab'

TV

Dr. Drew Pinsky said he will not continue doing "Celebrity Rehab."

Dr. Drew Pinsky has confirmed that he has officially checked out of "Celebrity Rehab."

The physician and reality TV star recently confirmed to the Zach Sang & the Gang radio program that there will be no more seasons of "Celebrity Rehab," mainly because he's tired of getting blamed when a celebrity he's treated ends up dying from their drug addiction.

"I don't have plans to do that again, " Pinsky said. "I'm tired of taking all the heat. It's just ridiculous."

Pinsky, who starred in and co-produced five seasons of "Celebrity Rehab," said that doing the show has become too stressful for him, due to the fact that everyone is quick to point fingers at him when one of his celebrity patients relapses.

"It's very stressful and very intense for me, " Pinsky said. "To have people questioning my motives and taking aim at me because people get sick and die because they have a life-threatening disease, and I take the blame? Rodney King has a heart attack and I take blame for that?"

Pinsky said that while many viewers think that much of what is shown on "Celebrity Rehab" is faked for the cameras, the show was very real.

"These are really sick people, that's why they die," Pinsky said. "These are people with life-threatening addiction. Bob [Forrest] and Shelly [Sprague] and I ran a program for 20 years and [for 'Celebrity Rehab'] we do what we always do and just let them run the cameras."

To date, five of Pinsky's "Celebrity Rehab" patients have died, most recently country singer Mindy McCready, who took her own life in February. Still, Pinsky credits the show for helping a lot of celebrities finally get clean.

"It's sad that we're not doing more shows because people did get help," he said. "A lot of people are sober because of 'Celebrity Rehab' who wouldn't have been sober without it."

Pinsky added that he credits actor Tom Sizemore as the show's biggest success story. The actor, who was featured on the show's third season, had been trying unsuccessfully to get clean for years before coming on the show.

"We worked with him 10 years before [he came on the show]," Pinsky said. "Bob and I worked with him a lot and couldn't get him sober. And he got sober on 'Celebrity Rehab.' That's awesome."

Pinsky has practiced addiction medicine for 20 years, and said he continues to work with patients every week, in addition to hosting the nightly "Loveline" radio program, as well as his own talk show, "Dr. Drew on Call" on the HLN channel.

U.N. head, Security Council envoys discuss Syria as mediator wants out

By Michelle Nichols

UNITED NATIONS (Reuters) - U.N. chief Ban Ki-moon and ambassadors from the United States, Britain, France, Russia and China discussed on Thursday "possible diplomatic moves to end" the Syria conflict after U.N. diplomats said mediator Lakhdar Brahimi was determined to quit.

Diplomats, speaking on the condition of anonymity, said on Wednesday that Brahimi wanted to resign from the joint U.N.-Arab League role because he is frustrated with international deadlock over how to end Syria's two-year war that has killed 70,000.

The envoys from the permanent five veto-wielding members of the U.N. Security Council declined to comment after meeting with the secretary-general. A dispute between Russia and the United States over Syria has left the council paralyzed.

Brahimi, appointed last year after former U.N. Secretary-General Kofi Annan resigned as Syria mediator, also wants to distance himself from the Arab League, envoys said, because of its decision to recognize Syria's opposition.

Brahimi felt that move undermined his neutrality. He could quit the joint mediator role and possibly be reappointed as an U.N. adviser to Ban an Syria, diplomats said.

Ban's spokesman Martin Nesirky said of Ban's meeting with the council envoys: "(They) discussed possible diplomatic moves to end the crisis. He briefed them on the latest developments relating to the chemical weapons investigation mission."

Syria has blocked unfettered access by the U.N. mission, which was created by Ban nearly six weeks ago and has an advance team in Cyprus ready to deploy to Syria. Diplomats say it is unlikely it will gain access any time soon.

The Syrian government and the opposition blame each other for alleged chemical weapons attacks in Aleppo in March and Homs in December. Ban wants the inquiry to look at both incidents, but Syria only wants the U.N. to probe the Aleppo attack.

U.S. President Barack Obama on Tuesday said that there was evidence that chemical weapons had been used in Syria, but that it was not yet known how the chemical weapons were used, when they were used and who used them.

Obama has warned Syria's government that the use of chemical weapons could trigger unspecified consequences. He told a news conference on Tuesday that he had asked the U.S. military to prepare options on Syria, but declined to give further details.

Forces loyal to President Bashar al-Assad retook a central district in the city of Homs on Thursday, driving a wedge between two isolated pockets of rebel resistance in Syria's third largest city, fighters and activists said.

Nesirky said Ban and the permanent five Security Council envoys also discussed on Thursday "the ever-worsening humanitarian situation inside Syria and the neighboring countries, and international efforts to alleviate it."

Five million people have fled their homes, including 1.4 million refugees in nearby countries, the United Nations says.
