da Are Casual Fridays dead? By feeds.scpr.org Published On :: Tue, 06 Aug 2013 12:21:30 -0700 Business Update with Mark LacterWe used to make a big deal out of Casual Fridays at work. But now that we're entering the dog days of summer, is anyone dressing up? Mark Austin Thomas: Business analyst Mark Lacter, dare I ask what you're wearing? Mark Lacter: This is radio for a reason, Mark! And certainly, don't ask that question at the L.A. Daily Journal newspaper, which recently issued a memo that laid down the law on what's not considered appropriate attire. As in, no jeans, no sneakers (except for messengers), no sandals or flip-flops, no halter tops, no spaghetti straps, no tee-shirts. Also, no shorts, leggings, or exercise pants. And, if you don't measure up, you may be sent home to change clothes - without pay for the time you've missed. Now, to be fair, the Daily Journal is a legal newspaper, and law firms - along with the courts - remain kind of a bastion for traditional business attire. Thomas: And that means jackets and ties for men...? Lacter: ...and skirt suits and business dresses for women. It's the same deal for many offices in New York and Chicago. Matter of fact, dressing down is still not especially popular in many parts of the country, according to a new survey I came across. More than half of the respondents say it suggests an employee doesn't have respect for the workplace. In other words, not a team player. Thomas: But L.A. has this huge creative community where jeans and tee-shirts are almost part of the uniform. Lacter: Yeah, the only people wearing suits at these places are the high-level executives who are actually called "suits." This has been true in Hollywood for years, but now you're seeing it with the growth of tech companies. Imagine how confusing it must be for an attorney who wears the standard business uniform, and who has one of these companies as his client. And, maybe that's the point - there is no single workplace culture, even within the companies themselves. Thomas: Is being comfortable just not on the radar at these places? Lacter: Well, not to pick on the Daily Journal, but so what if someone who is stuck in front of a computer all day wants to be a little more comfortable in jeans? Will the world as we know it come to a halt? You know, the workplace is far different than it was even 10 years ago. People are doing their jobs in all sorts of ways, whether it's working from home, or as independent contractors. And, this is really all about common sense - so, maybe it's time the stick-in the-muds realized as much. Thomas: Attire aside, how is the workplace itself changing? Lacter: Some of those downtown law firms have been cutting back, which means that they don't need as much space. Not every attorney needs a giant office. Same with the downtown accounting firms - when folks do go to work, the office may include a fancy kitchen, a ping pong table, workstations that double as treadmills, a place to do yoga or even to take a nap. Thomas: All this is supposed to boost productivity... Lacter: ...which it probably does, though you do have to wonder whether having a yoga room really enhances output, or is just a way of keeping employees from not taking a job somewhere else. My favorite perk, and I say that facetiously, is the office kegerator, which not only seems like a dumb idea, but a great way for a company to get sued if somebody has one too many. Thomas: Quickly Mark, any news in the dispute between CBS and Time Warner Cable? Lacter: Not good news. Time Warner Cable offered what it said were two possible solutions to the standoff, but CBS has came back and called it a sham. Time Warner Cable subscribers have been without CBS programming since Friday, which is already going on longer than analysts had first expected. The fight is over re-transmission fees - the amount of money that a programmer receives from a distributor- in this case, Time Warner Cable. CBS apparently wants a big increase, and Time Warner Cable doesn't want to pay. Mark Lacter is a contributing writer for Los Angeles Magazine and writes the business blog at LA Observed.com.

da How Trader Joe's is handling the Affordable Care Act By feeds.scpr.org Published On :: Tue, 24 Sep 2013 12:46:21 -0700 Business Update with Mark LacterSign ups for the Affordable Care Act start in a week, and the program is leading to changes in the way employers handle health coverage. Steve Julian: Business analyst Mark Lacter, what's the most noticeable adjustment? Mark Lacter: Steve, once you get beyond the squabbling over efforts to defund the new law, what's happening is quite remarkable: businesses are finding new ways to administer and pay for coverage - and some would say it's long overdue. One interesting example: the grocery chain Trader Joe's, which is based in Monrovia, employs over 20,000 people, and shells out millions of dollars a year in helping provide its people with health insurance. Well, Trader Joe's has decided to end coverage for part-timers working fewer than 30 hours a week - under the new law businesses are not obligated to provide benefits to employees who work less than that amount. However, the company is giving those people $500 to go towards the purchase of premiums at the new public exchanges. And that, along with the tax credits available, could make the new arrangement cost about the same or even cheaper than the current health care package. Julian: How did TJ's explain this to its employees? Lacter: The company cited the example of an employee with one child who makes $18 an hour and works 25 hours a week. Under the old system, she pays $166 a month for coverage; under the new system, she can get a nearly identical plan for $70 a month. Now, there are cases in which workers will end up paying more - usually it involves having a family member who makes more money, but who doesn't have access to coverage (good example would be an independent contractor or freelancer). By the way, other companies - including the drug store chain Walgreen's - are also moving part-timers to the public market, and offering some sort of a subsidy. Julian: I imagine not all companies are being as conscientious... Lacter: No. We've seen a number of corporations cut worker hours and not offer a supplemental payment. Steve, it's worth remembering that administering health insurance is something that businesses fell into quite by accident 60 years or so ago - premiums cost next to nothing at the time, and it was seen as way of attracting workers without having to jack up wages. The arrangement became more attractive over the years because of certain tax benefits. But, it's far from ideal - workers move from job to job more often than they used to, and not all businesses are capable of handling the extra costs, especially small businesses. Julian: Doesn't L.A. have a higher percentage of uninsured than elsewhere? Lacter: Considerably higher - the Census Bureau show that 21 percent did not have coverage in 2012, which is higher than the overall national number. Now, there are a bunch of reasons for this: L.A. has a large percentage of households that simply can't afford health insurance or don't have access to government programs, among them undocumented immigrants. You also have big numbers of people who are self-employed and don't get covered - we're talking about freelancers or consultants of some sort. Julian: …Or, they work for small businesses whose owners either can't afford, or don't want to provide coverage… Lacter: That's right - the new law only requires businesses with more than 50 full-time workers to offer health insurance, and a lot of small businesses don't meet that threshold. The Census Bureau says that in the L.A. area, one in four people with jobs do not have health insurance - and, by the way, there's been a drop-off both in the percentage of businesses in California that offer coverage. Julian: Sounds dire. Who picks up the cost? Lacter: Well, we all do in one way or another - and that, of course, is the problem. What the Affordable Care Act offers is a start in getting some of the uninsured onto the rolls. Clearly, it's an imperfect solution that will require all sorts of adjustments, and even though everyone and their uncle seems to have formed a definitive opinion about the new law, it's going to be years before there's any real sense of how it's going. And, let's remember, signing up for these programs is not some political act. It's just a way for people to get health insurance for themselves and their families.

da Updating direct methods By scripts.iucr.org Published On :: 2019-01-01 The standard method of joint probability distribution functions, so crucial for the development of direct methods, has been revisited and updated. It consists of three steps: identification of the reflections which may contribute to the estimation of a given structure invariant or seminvariant, calculation of the corresponding joint probability distribution, and derivation of the conditional distribution of the invariant or seminvariant phase given the values of some diffracted amplitudes. In this article the conditional distributions are derived directly without passing through the second step. A good feature of direct methods is that they may work in the absence of any prior information: that is also their weakness. Different types of prior information have been taken into consideration: interatomic distances, interatomic vectors, Patterson peaks, structural model. The method of directly deriving the conditional distributions has been applied to those cases. Some new formulas have been obtained estimating two-, three- and four-phase invariants. Special attention has been dedicated to the practical aspects of the new formulas, in order to simplify their possible use in direct phasing procedures. Full Article text
