Mr. Joe Sample and the Jazz Crusaders gave some of the best live performances ever!  If they had a concert within a few hundred miles radius of where I lived, I found a way to get there - no matter what.

Thank you Mr. Sample.  Your amazingly beautiful music lives on - forever.  R.I.P. sir!

The "Stock Act" Allows Top Federal Employees To Trade on Inside Information

by Iris Mack, PhD, EMBA on September 9, 2014 0 Comments

Huffington Post


Who says nothing ever gets done in Washington? Swiftly and without fanfare, Congress and President Obama have made it easier for top federal employees to trade on inside information.

On Monday, Obama signed into a law a change in the Stop Trading On Congressional Knowledge, or STOCK Act, which was passed in 2012. The change, which was approved unanimously by Congress last week, means that top federal employees, including staffers on Capital Hill and in the White House, will not have to publicly disclose their financial holdings online. That requirement was part of the original STOCK Act, but its implementation had been delayed again and again by Congress. And now it's dead.

The STOCK Act change does not apply to the president, vice president, members of Congress or candidates for Congress. Obama and Congress loudly passed the original STOCK Act last ...

Ex-SAC Trader Sentenced to 9 Years in Prison for Insider Trading Scheme

by Iris Mack, PhD, EMBA on September 4, 2014 0 Comments


by Matthew Goldstein


Mathew Martoma was sentenced to nine years in prison on Monday for carrying out one of the biggest insider trading schemes on record in 2008 when he was working as a portfolio manager at Steven A. Cohen’s former hedge fund, SAC Capital Advisors.

The sentence was in line with what the government was seeking. Prosecutors working for Preet Bharara, the United States attorney for the Southern District of New York, had asked for a prison term of eight years or more for Mr. Martoma, who was convicted in February by a federal jury in Manhattan. Mr. Martoma’s lawyers had simply asked Judge Paul G. Gardephe to show mercy and sentence him to a significantly shorter term.

In handing down the sentence, Judge Gardephe said, “The sums here are staggering and the size of the punishment must be sufficient to deter others.”

Mr. Martoma was ...

A friend of mine just told me that I used to walk around U.C. Berkeley's math department singing this Bobby Caldwell song. I guess I was in my own little math geeky world - oblivious to the fact that I was disturbing the peace. LOL!

Bobby Caldwell has what is known as blue-eyed soul. Enjoy!

Forbes: U.S. Hikes Fee To Dump Your Passport By 422%

by Robert W. Wood


Over the last two years, the U.S. has had a spike in expatriations. It isn’t exactly Ellis Island in reverse, but it’s more than a dribble. With global tax reporting and FATCA, the list of the individuals who renounced is up. For 2013, there was a 221% increase, with record numbers of Americans renouncing. The Treasury Department is required to publish a quarterly list, but these numbers are under-stated, some say considerably.

The presence or absence of tax motivation is no longer relevant, but that could change. AfterFacebook co-founder Eduardo Saverin departed for Singapore, Senators Chuck Schumer and Bob Casey introduced a bill to double the exit tax to 30% for anyone leaving the U.S. for tax reasons. That hasn’t happened, but taxes are still a big issue for many.

To leave America, you generally must prove 5 years ...

Paris (AFP) - IMF chief Christine Lagarde, one of the world's most powerful women, announced Wednesday she had been charged with "negligence" over a multi-million-euro graft case relating to her time as French finance minister.


The shock announcement came a day after she was grilled for more than 15 hours by a special court in Paris that probes ministerial misconduct, the fourth time she has been questioned in a case that has long weighed upon her position as managing director of the International Monetary Fund.

Fuel Fix: Uncle Sam Collects $110 Million From Offshore Oil Auction

by  Jennifer A. Dlouhy in OffshorePolitics/Policy

WASHINGTON — Oil and gas companies are set to pay the government $110 million in high bids for leases in the western Gulf of Mexico, after an auction Wednesday that underscored the industry’s interest in deep-water territory.

Fourteen companies participated in the sale, which nominally put 21 million acres up for grabs, though ultimately, just 81 blocks spanning 433,823 acres were sold.

The industry’s interest was concentrated on the Alaminos Canyon area and territory near the U.S.-Mexico maritime border that had been off limits for development while the two countries enacted a treaty to govern oil development.

McKinsey Report: Digitizing Oil & Gas Production

by Iris Mack, PhD, EMBA on August 20, 2014 0 Comments


The authors of a recently published McKinsey report believe further automation can play a major role in addressing the following challenges in the oil and gas industries:

More complex operations. Increasing volume and complexity in hostile, remote locations (for example, arctic, offshore, and deepwater) require reliable remote and automated or semiautomated operations, and logistics optimized for efficiency. Mature assets with declining production need very efficient maintenance schedules to keep production profitable.

Zero tolerance for health, safety, and environmental incidents. This is a nonnegotiable imperative. Recent industry experience has shown that in the current highly regulated environment, such incidents can threaten not only profitability but also the very existence of an operator. Automated production control, monitoring the condition of the equipment, and predictive shutdown systems are now basic requirements to prevent or mitigate catastrophic events in geographically dispersed remote operations.

The talent and experience gap. The industry is in the most ...

Stanford Professor Maryam Mirzakhani: First Woman to Win the "Nobel Prize" of Mathematics

by Iris Mack, PhD, EMBA on August 20, 2014 0 Comments


For the first time in history, a woman has received the highest honor in mathematics, often nicknamed the Nobel Prize of mathematics.

Since it was established in 1936, the Fields Medal had gone only to men, until Wednesday, when Maryam Mirzakhani received it in Seoul, South Korea, from the International Mathematical Union.

"This is a great honor. I will be happy if it encourages young female scientists and mathematicians," Mirzakhani said, according to a statement from Stanford University, where she is a professor.

Former MIT Dean Gabriel Bitran Pleads Guilty to Running a $500 Million Scam - Connected to Madoff's Ponzi Scheme

Former Associate Dean at MIT's Sloan School of Management Pleads Guilty in Hedge Fund Scam

A former Massachusetts Institute of Technology professor and his son have agreed to plead guilty (DOJ) to running a $500 million hedge-fund scam that was uncovered by investigators probing Bernard Madoff’s Ponzi scheme.

Gabriel Bitran, who was a chair professor and associate dean at MIT’s Sloan School of Management (VisualCV), and his son, Marco, told investors that their money management firm GMB Capital Management LLC had a successful real world track record, when in fact they simply assembled back data that would show a spectacular track record.

The men, who raised more than $500 million from 2005 to 2011, meanwhile put money into “funds of funds,” (Blm) which rely on investments by other hedge funds, mostly Bernie Madoff’s firm and Madoff feeder funds, according to prosecutors.

The Bitrans’ funds suffered losses ...
