Single-wavelength X-ray anomalous diffraction (SAD) is a frequently employed technique to solve the phase problem in X-ray crystallography. The precision and accuracy of recovered anomalous differences are crucial for determining the correct phases. Continuous rotation (CR) and inverse-beam geometry (IBG) anomalous data collection methods have been performed on tetragonal lysozyme and monoclinic survivin crystals and analysis carried out of how correlated the pairs of Friedel's reflections are after scaling. A multivariate Bayesian model for estimating anomalous differences was tested, which takes into account the correlation between pairs of intensity observations and incorporates the a priori knowledge about the positivity of intensity. The CR and IBG data collection methods resulted in positive correlation between I(+) and I(−) observations, indicating that the anomalous difference dominates between these observations, rather than different levels of radiation damage. An alternative pairing method based on near simultaneously observed Bijvoet's pairs displayed lower correlation and it was unsuccessful for recovering useful anomalous differences when using the multivariate Bayesian model. In contrast, multivariate Bayesian treatment of Friedel's pairs improved the initial phasing of the two tested crystal systems and the two data collection methods.

The generalized Darwin–Hamilton equations [Wuttke (2014). Acta Cryst. A70, 429–440] describe multiple Bragg reflection from a thick, ideally imperfect crystal. These equations are simplified by making full use of energy conservation, and it is demonstrated that the conventional two-ray Darwin–Hamilton equations are obtained as a first-order approximation. Then an efficient numeric solution method is presented, based on a transfer matrix for discretized directional distribution functions and on spectral collocation in the depth coordinate. Example solutions illustrate the orientational spread of multiply reflected rays and the distortion of rocking curves, especially if the detector only covers a finite solid angle.

Businesses are cutting back on hours to avoid having to provide health care coverage under the new Affordable Care Act.

Steve Julian: Business analyst Mark Lacter, who's affected here?

Mark Lacter: Thirty hours a week is the magic number for workers to be considered full time under the new law.  If a business has 50 or more full-time employees, health care coverage has to be provided.  Except that a lot business owners say that the additional cost is going to be a financial killer, so instead, some of them have been cutting back hours to below that 30-hour threshold.  More than 200,000 Californians are at risk of losing hours from the health care law - that according to one study.

Julian: What kinds of businesses are doing this?

Lacter: Restaurant chains have received much of the attention, but the city of Long Beach, as an example, is going to reduce hours for a couple of hundred of its workers.  And, last week came word that the L.A.-based clothing chain Forever 21 will cut some of its full-time employees to a maximum 29-and-a-half hours a week, and classify them as part time.  That touched off an outcry on the Internet - people were saying that Forever 21 was being unfair and greedy - though the company says that only a small number of employees are affected, and that its decision has nothing to do with the Affordable Care Act.  There's really no way to know - Forever 21 is a private company, which means it's not obligated to disclose a whole lot.  What we do know is that those people will be losing their health care coverage.

Julian: And, the ultimate impact on businesses and workers?

Lacter: Steve, you're looking at several years before the picture becomes clear.  Here in California, workers not eligible for health care through their employer can get their own individual coverage, and if their income levels are not over a certain amount, they'd be eligible for Medicaid.  And, let's not forget many businesses already provide coverage for their employees.  So, lots of rhetoric - but, not many conclusions to draw from, which does make you wonder why so many business owners are unwilling to at least give this thing a chance.  Just doesn't seem to be much generosity of spirit for their workers, not to mention any recognition that if people can go to a doctor instead of an emergency room we'd probably all be better off.

Julian: Health care is far from the only controversy for Forever 21, true?

Lacter: In some ways, it's one of the biggest Southern California success stories.  Don Chang emigrated here in 1981 from Korea at the age of 18, opened his first store in Highland Park three years later (it was called Fashion 21), and he never looked back.  Today, revenues are approaching $4 billion.  But, the guy must have some pretty hefty legal bills because his company has been accused of all kinds of workplace violations.  The lawsuits alleged that workers preparing items for the Forever 21 stores didn't receive overtime, that they didn't get required work breaks, that they received substandard wages, and that they worked in dirty and unsafe conditions - sweatshop conditions, essentially.

Julian: Are most of their claims settled out of court?  You don't hear much about them.

Lacter: They are, which means there's usually a minimal amount of media coverage.  If a privately held company decides to keep quiet by not releasing financial results or other operational information, there's not likely to be much of a story - unlike what happens with a company like Apple, which is always under scrutiny.  Sometimes, plaintiffs will try to organize class-action suits, but that's extremely tough when you're dealing with low-wage workers who are often very reluctant to get involved because of their legal status.  And, let's not forget that Forever 21 - like any low-cost retailer - is simply catering to the demand for cheap, stylish clothes that are made as quickly as possible.

Julian: I guess you can't make that happen when wages and benefits are appreciably higher than your competition.

Lacter: The next time you walk into a Forever 21 store and wonder how prices can be so reasonable, that's how.

When you look at fast growing private companies in the U.S., you need look no further than a small city next to Los Angeles International Airport.

Steve Julian: Business analyst Mark Lacter, tell us about the company that's based in El Segundo.

Mark Lacter: It's called Fuhu, Steve - that might ring a bell with some parents because Fuhu is the maker of the Nabi.  The Nabi is an Android tablet for kids, and it's a very cool device that mimics a lot of the capabilities of regular tablet, including the ability to play games and get onto the Web (with controls that parents are able to set up).  Last year, they sold 1.2 million Nabis, and that helped push the El Segundo company to the very top of Inc. magazine's list of fastest-growing businesses.  That's number one on a list of 5,000 companies, with a three-year growth rate of 42,148 percent.  Or, to put it another way, company revenue was $279,000 in 2009; it was almost $118 million in 2012.  Now, by the standards of an Apple or a Samsung, those are still not huge numbers -

Julian: - and maybe that explains why there's been relatively little media coverage of this company.

Lacter: It might also explain why local tech companies in general get short shrift.  Many of them are quite successful, but they're often on the small side, and they're also privately held as opposed to publicly-traded on a stock exchange.  That's one big difference from Silicon Valley, which has so many huge public corporations: Apple, Intel, HP.  L.A. County has only six Fortune 500 companies, and not a single one devoted solely to technology.  In Silicon Valley, there are 22 in the Fortune 500.

Julian: And yet, the L.A. economy has more than held its own without those large corporations.

Lacter: Matter of fact, the accounting firm PriceWaterhouse studied more than two dozen cities around the world to determine where it was easiest to do business (that's based on factors like access to labor), and what they found - somewhat surprisingly - was that L.A. ranked ahead of both San Francisco and Tokyo.  And, you can see evidence of that with the increase in venture capital money coming into all parts of L.A.  Now, it's important to keep an eye on all these up-and-coming companies because these businesses are helping generate higher-wage jobs.  And, for an area with a still-high unemployment rate - still over 10 percent in some places -- that's a big deal.

Julian: Speaking of companies, does anyone want to buy the L.A. Times?

Lacter: The answer is yes - most recently, the controlling owner of the Dodgers, Mark Walter, said he was interested in both the Times and the Chicago Tribune (though there's no way to know whether there are actual discussions taking place).  You also have several local groups, including one that involves billionaire Eli Broad, that have been interested to one degree or another.  But what was thought would be a fairly straightforward auction process has turned enormously complicated.  It's now to the point where the Tribune board has decided spin off the papers into a separate business, and that process will take until next year to complete and could preclude any sales for quite some time after that.

Julian: So, it's Limbo-land for the Times for who knows how long.

Lacter: Steve, it's not that Tribune really wants to keep the newspapers.  But, selling them off presents huge tax implications.  Also, there are assets that the potential buyers thought would be part of the package - assets that include real estate - that Tribune wants to hold onto.  So, what's left to sell are just the newspapers themselves, and frankly, they're among the least valuable properties.

Julian: Now, last week came word that the billionaire Koch brothers, who were believed to be interested in the Tribune properties, decided not to pursue a deal...

Lacter: ...that's right, they don't consider the Times or the other dailies to be economically viable.  You might recall a bit of an outcry over the prospect of having the Kochs, who are staunch conservatives, becoming the owners of these papers.  So, they're out of the picture.  But for the L.A. Times, it's really the worst of all worlds: no new owner and no vision for recasting the paper, at least in the near term.

The partial federal government shutdown is one week old, but economists are still saying that its impact in Southern California and elsewhere will be limited.

Susanne Whatley: Business analyst Mark Lacter, why is that?

Mark Lacter: If you look back on the history of these things, Susanne, you see that the disputes are resolved before too much damage gets done.  As for Southern California, I notice that KPCC's Alice Walton was asking around over the weekend about the shutdown, and most folks gave it a shrug.  The regional economy is just too diversified - and not especially tied to federal employment.  You have about 46,000 federal workers employed in L.A. County in one capacity or another - that's out of a workforce of nearly 5 million.  And, now it appears as if the federal employees who have been furloughed are going to receive their back wages whenever the shutdown finally ends.

Whatley: That still might make things dicey when it comes time to pay the monthly mortgage...

Lacter: ...but at least money will be available before most folks run into serious liquidity issues.  That's what the shutdown really comes down to - inconvenience rather than dislocation.  And, you see this with the various government services affected: the E-Verify website is down - that lets business owners know whether the people they're wanting to hire can work legally in the U.S., which obviously is important.  The Small Business Administration has stopped processing loan applications, and the Federal Housing Administration is reporting delays in its loan processing, which could mean a home buyer might not complete his or her paperwork all that quickly.

Whatley: But, what if this were to go on for months?

Lacter: Well, then it would create problems, but nobody really thinks that's going to happen.  The real issue, not just nationally and regionally - but globally - is the refusal by Congress to raise the debt ceiling.  The deadline is a week from Thursday, and - of course - there's been all sorts of debate about what this would mean for the economy.

Whatley: All right, so what would this mean for the economy?

Lacter: Well, no one knows exactly.  But, then again, no one knows exactly what would happen if you fell out of a airplane without a parachute.  I just wouldn't want to test it out.  And, of course, let's keep in mind that these are manufactured crises - not reflective of anything that's going on with the real economy.  It's certainly not reflective of anything that's going on in L.A., which saw a big jump in payroll jobs for 2012 - actually it was the sharpest increase since 2005, and nearly double the national rate (that's despite an unemployment rate that remains very high in certain parts of Los Angeles).

Whatley: What about some of the big locally based companies?

Lacter: Well, if your company is publicly traded, there's a good chance your shares took a dip these past few days.  Going back to September 18, the Dow has lost almost 700 points, which - percentage-wise - is not very much, but it is reflective of how uneasy Wall Street has become.  Public companies based in the L.A. area are taking it on the chin - Disney, Amgen, Mattel, DirecTV - their stock prices are all down going back to the middle of September.

Whatley: Even so, hasn't this been a good year for the stock market?

Lacter: It has - those local companies are up anywhere from 13 percent 30 percent year to date, and the Dow is up 14 percent year to date.  Of course, the stock price of a company doesn't always match the amount of money it makes, and this year, even before worries about the debt ceiling, the numbers haven't been as good as they should be at this stage of a recovery.  And, that's why there's particular concern about next week.  You do have to wonder whether a default could have ripple effects involving trade, consumer spending, the dollar - who knows what?  Now, it's still a pretty good bet that saner heads will prevail, although there are no guarantees - and again, if worse came to worse, do you really want to be jumping out of that plane?  Guess we'll find out.
