Wall Street Beats London's City in Pay for Middle Office Workers
Pay
Middle office professionals should move to Wall Street if they?re chasing money, but stick to the City of London if they want more career opportunities.
Pay for senior risk and compliance professionals working in banking in New York outstrip those for equivalent roles in London, Continental Europe and Asia, according to the 2013 salary survey released today by recruiters Robert Walters. Risk and compliance roles at banks are among the few ?for which the survey compares pay globally.
A senior compliance professional working in an investment bank in New York can expect between $250-525k, suggests the survey, while an equivalent role in London pays a maximum of $232k. In fact, Wall Street compliance pay outstrips every other geography; Singapore is the closest competitor with senior salaries out up to $298k.
Not surprisingly, with the onslaught of regulation, compliance recruitment remained high globally, suggests the survey, with hedge funds, commercial banks and investment banks alike all competing for talent.
It?s more of a mixed job market for risk professionals, however. In London, risk recruitment ?remained high throughout 2012?, particularly in operational risk, and has continued to be active throughout the first few weeks of 2013, says Robert Walters.
In New York, meanwhile, banks are less likely to recruit risk professionals. ?With the potential restrictiveness of Dodd-Rank remaining unclear, many bulge bracket firms were cautious in their risk management hiring approaches,? said the survey. ?Firms also looked to fill many roles with internal candidates whenever possible.?
We?ve outlined compensation for risk and compliance jobs globally below, but the U.S. figures for risk roles include bonus payments so aren?t directly comparable. However, middle office bonuses have traditionally comprised a small proportion of total compensation relative to front office positions. We have requested base salary figures for U.S. risk jobs ?from Robert Walters.

Biological marker predicts susceptibility to common cold
Feb. 19, 2013 ? Researchers at Carnegie Mellon University have identified a biological marker in the immune system that -- beginning at about age 22 -- predicts our ability to fight off the common cold.
Published in the Journal of the American Medical Association (JAMA) and led by Carnegie Mellon's Sheldon Cohen, the study found that the length of telomeres -- protective cap-like protein complexes at the ends of chromosomes -- predicts resistance to upper respiratory infections in young and midlife adults. Telomere length is a biomarker of aging with telomeres shortening with increasing chronological age. As a cell's telomeres shorten, it loses its ability to function normally and eventually dies. Having shorter telomeres is associated with early onset of aging related diseases such as cardiovascular disease and cancer, and with mortality in older adults. Unknown until now is whether telomere length plays a role in the health of young to midlife adults.
"Our work suggests the possibility that telomere length is a relatively consistent marker across the life span and that it can start predicting disease susceptibility in young adulthood," said Cohen, the Robert E. Doherty Professor of Psychology in CMU's Dietrich College of Humanities and Social Sciences. "We knew that people in their late 50s and older with shorter telomeres are at a greater risk for illness and mortality. We also knew that factors other than aging, such as chronic stress and poor health behaviors, are associated with shorter telomeres in older people. Consequently, we expected that younger people would vary in their telomere length as well and wanted to see what this would mean for their health."
Cohen and his team measured the telomere length of white blood cells from 152 healthy volunteers aged 18-55. These individuals were then exposed to a rhinovirus, which causes a common cold, and quarantined for five days to see if they actually developed an infection.
The results showed that participants with shorter telomeres were more likely to become infected by the cold virus. Further, although there was no relationship between telomere length and infection among the youngest participants (ages 18-21), beginning at about age 22, telomere length started to predict whether individuals would develop an infection. As participant age increased, telomere length became an even stronger predictor. Additionally, telomere length of a specific type of white blood cell -- a CD8CD28- T-cytolytic cell -- was a superior predictor of infection and cold symptoms than other white blood cell types. The telomeres found in CD8CD28- cells shorten more quickly than those found in other cell types, and previous research has found shorter telomere length in these cells to be associated with decreases in markers of immune competence.
"These cells are important in eliminating infected cells and those with shorter telomeres in the CD8CD28- cell population may be at greater risk for infection because they have fewer functional cells available to respond to the [cold] virus," Cohen said. "The superior ability of CD8CD28- T-cytolytic cells to predict infection gives us an idea of which cells to focus on in future work on how telomere length influences the immune system's response to infection and other immune-related challenges."
Cohen added, "The increased importance of telomere length with age is likely because the younger participants had fewer very short telomeres, or that their young immune systems were able to compensate for the loss of effective cells."
Cohen emphasized that "this is preliminary research and further work with other viruses and with natural infections will help clarify its implications."
In addition to Cohen, the research team included CMU's Denise Janicki-Deverts; the University of Virginia Health Sciences Center's Ronald B. Turner; Children's Hospital of Pittsburgh's Margaretha L. Casselbrant, Ha-Sheng Li-Korotky and William J. Doyle; and Elissa S. Epel of the University of California, San Francisco.
The National Center for Complementary and Alternative Medicine and the National Institute of Allergy and Infectious Diseases funded this research, with supplemental support from the MacArthur Foundation's Research Network on Socioeconomic Status and Health, the Eberly Foundation, the Hamburg Fellowship and National Institutes of Health funding to the University of Pittsburgh Clinical and Translational Science Institute.

Inmate wanted Bieber castrated, suffocated

By Bruna Nessif, E! Online
Things just got a little scarier. News of a possible murder plot formulated by an inmate and two fugitives against pop star Justin Bieber made headlines in December, and now the details behind that conspiracy have unraveled after the audio of phone calls made last November from a prison near Las Cruces, N.M., were released.
Police told ABC News ' Albuquerque affiliate KOAT that inmate Dana Martin, who is doing time at the Southern New Mexico Correctional Facility for the murder and rape of a 15-year-old girl, was the mastermind behind the plot.
A Justin Bieber murder plot?
According to police, Martin directed a former jailhouse friend in Vermont, Mark Staake, and Staake's nephew, Tanner Ruane, to carry out the kidnapping and murder, and asked Ruane in a taped conversation, "Did he go over the Bieber thing with you?"
"Nah. The way I like to work dude, I like to know as little as possible," Ruane replied. "He's gonna use one of the things you gave him, and then he's gonna take care of it." Oh, and it gets worse.
"We went and bought the hedge clippers," Ruane said. "You're gonna give me 5 large ($5,000) for each one I get." Police said that Ruane was instructed to castrate Bieber and his bodyguard with the clippers, and then suffocate them with a scarf.
"Tie it really tight, and that cuts off all the oxygen, and then tie it in the back again, really tight. That seals the deal," Martin was heard saying.

Luckily, before any of this could take place, Staake and Ruane were arrested by border patrol agents after making a wrong turn in to Canada. They, along with Martin, now face two counts each of conspiracy to commit murder and two counts each of conspiracy to commit aggravated battery.
Bieber's camp were not immediately available for comment, but told E! News when the plot first came about in December, "We take every precaution to protect and insure the safety of Justin and his fans."

Dopants dramatically alter electronic structure of superconductor
Monday, February 18, 2013
Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into "superconductors" able to carry electrical current with no energy loss-an enormously promising idea for new types of zero-resistance electronics and energy-storage and transmission systems. At present, a key step to achieving superconductivity (in addition to keeping the materials very cold) is to substitute a different kind of atom into some positions of the "parent" material's crystal framework. Until now, scientists thought this process, called doping, simply added more electrons or other charge carriers, thereby rendering the electronic environment more conducive to the formation of electron pairs that could move with no energy loss if the material is held at a certain chilly temperature.
Now, new studies of an iron-based superconductor by an international team of scientists - including physicists from the U.S. Department of Energy's Brookhaven National Laboratory and Cornell University - suggest that the story is somewhat more complicated. Their research, published online in Nature Physics February 17, 2013,* demonstrates that doping, in addition to adding electrons, dramatically alters the atomic-scale electronic structure of the parent material, with important consequences for the behavior of the current-carrying electrons.
"The key observation - that dopant atoms introduce elongated impurity states which scatter electrons in the material in an asymmetric way - helps explain most of the unusual properties," said J.C. S?amus Davis, the study's lead author, who directs the Center for Emergent Superconductivity at Brookhaven Lab and is also the J.G. White Distinguished Professor of Physical Sciences at Cornell University. "Our findings provide a new starting point for theorists trying to grapple with how these materials work, and could potentially point to new ways to design superconductors with improved properties," he said.
The researchers used a technique developed by Davis called spectroscopic imaging scanning tunneling microscopy to visualize the electronic properties around individual dopant atoms in the parent material, and to simultaneously monitor how electrons scatter around these dopants (in this case, cobalt).
Earlier studies had shown that certain electronic properties of the non-superconducting "parent" material had a strong directional dependence - for example, electrons were able to move more easily in one direction through the crystal than in the perpendicular direction. However, in those studies, the signal of a strong directional dependence only appeared when the scientists put the dopants into the material, and got stronger the more dopants they added.
Before this, the assumption was that dopants simply added electrons, and that the material's properties - including the emergence of superconductivity - were due to some intrinsic characteristic (for example, the alternating alignments of electron spins on adjacent atoms) that resulted in a directional dependence.
"But the emergence of directional dependence of electronic properties as more dopants are added suggests that the strong directionality is a result of the dopants, not an intrinsic property of the material," Davis said. "We decided to test this idea by directly imaging what each dopant atom does to the nearby atomic-level electronic structure in these materials."
According to Davis, the current paper reports two very clear results:
1) At each cobalt dopant atom, there is an elongated impurity state-a quantum mechanical state bound to the cobalt atom-that aligns in a particular direction (the same for each cobalt atom) relative to the overall crystal. 2) These oblong, aligned impurity states scatter the current-carrying electrons away from the impurity state in an asymmetric way - similar to the way ripples of water would propagate asymmetrically outward from an elongated stick thrown into a pond, rather than forming the circular pattern produced by a pebble.
"These direct observational findings explain most of the outstanding mysteries about how the electrical current moves through these materials - for example, with greater ease perpendicular to the direction you would expect based solely on the characteristics of the parent material," Davis said. "The results show that the dopants actually do dramatic things to the electronic structure of the parent material."
"It's possible that what we've found could be similar to an effect dopants had on early semiconductors," Davis said. "Early versions of these materials, though useful, had nowhere near the performance as those developed after the 1970s, when scientists at Bell Labs figured out a way to move the dopant atoms far away from the electrons so they wouldn't mess up the electronic structure." That advance made possible all the microelectronics we now use every day, including cell phones, he said.
"If we find out the dopant atoms are doing something we don't want in the iron and even copper superconductors, maybe we can find a way to move them away from the active electrons to make more useful materials."
