When talk turns to the economy, it's clear that LA brings out the best and the worst.

Steve Julian: Business analyst Mark Lacter, where do you see the best of it here?

Mark Lacter: You see the best of the economy, Steve, with all kinds of startup activity - much of it tech-related - and you also see the large number of auto sales, the improved housing market, and the record number of people visiting Southern California - all indications of a growing economy.  But then, you have the other L.A. economy, with large numbers of families struggling to make ends meet, and seeing very little sign of recovery.  You know, the government has been releasing income data covering the last few years, and what you see is that the disparity between the richest 1 percent and the other 99 percent is at its widest point since the 1920s.  You especially see that kind of bifurcated economy in Southern California, which has some of the wealthiest people in the country, and also some of the poorest.

Julian: Now, the split between rich and poor has been happening for a good long time, hasn't it?

Lacter: Yes, but L.A. is in a special class because there are so many immigrants with limited job skills - in fact, a new study by the UCLA Anderson Forecast says it's a much higher percentage than immigrants living in Miami, San Francisco, and New York.  What's interesting is that 20 years ago the job skills among immigrants were significantly higher in L.A.  Limited job skills mean there's very little opportunity to move up the income ladder.  That factors into buying homes, sending your kids to college - really becoming part of the middle class.

Julian: I imagine that's particularly true for factory work…

Lacter: Yes, some of the same jobs that newly-arrived immigrants in previous generations would gravitate to.  Today, many of those jobs are gone, and they're being replaced by positions that require greater skill that's borne out of greater education.  And that, of course, is another problem: a sizable percentage of recently-arrived immigrants never finished high school, much less college, and that makes it even less likely that they'll be able to move up.

Julian: Related, or unrelated, to the recession?

Lacter: Actually, L.A. had serious income inequality in December of 2006, before the recession, when the county's unemployment rate was just 4.3 percent - a stunningly low rate when you consider that as of July, the jobless rate was almost 10 percent.  This points out that the division of haves and have-nots can happen even when the economy is doing well.

Julian: And it seems the last C-17 to be built for Air Force is a reminder of wage gap.

Lacter: That's right - it'll be up to foreign customers to keep the program in Long Beach alive.  Boeing currently has an order from India for 10 of the cargo planes, which will keep the line moving through the third quarter of next year.  Frankly, the only reason the C-17 has lasted this long is heavy political pressure by congressional lawmakers whose districts have an economic stake in the program.  At one time, as many as 16,000 people may have worked on the C-17 in Long Beach, but that number has fallen sharply over the years.

Julian: Still, this is the last airplane manufacturing plant in Southern California.

Lacter: And that, of course, speaks volumes about the state of the aerospace business, which had been one of the main economic drivers back in the days leading up to World War II.  Aerospace continued to be very important until the end of the Cold War, when you had a huge industry consolidation that resulted in the loss of tens of thousands of local jobs throughout the 1990s.  There's still quite a bit of aerospace activity locally that involves missiles, satellites, and electronics - both for the major defense contractors like Boeing and Northrop, and for smaller contractors and sub-subcontractors that still get a piece of the military pie.

Julian: But most of them require high skill levels…

Lacter: Yes, and that gets us back to the folks who are stuck in low-paying jobs with little prospect for moving up.  This is what the L.A. economy is all about, the good and the bad.

Sign 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.

This article aims to encourage practitioners, young and seasoned, by enhancing their structure-determination toolboxes with a selection of tips and tricks on recognizing and handling aspects of data collection, structure modelling and refinement, and the interpretation of results.

In the first reported crystal structure involving the potential ligand N,N',N''-tris­(2-pyridin­yl)-1,3,5-benzene­tricarboxamide, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules via their amide groups into slanted ladder-like chains. Only two of the three amide groups in the mol­ecule are involved in hydrogen bonding, which influences the degree of out-of-plane twisting at each amide group.

In the structure of the title salt, second-order Jahn–Teller distortion of the coordination octa­hedra around V ions is reflected by coexistence of short V—O bonds and trans-positioned long V—F bonds, with four equatorial V—F distances being inter­mediate in magnitude. Hydrogen bonding of the anions is restricted to F-atom acceptors only, with particularly strong N–H⋯F inter­actions [N⋯F = 2.5072 (15) Å] established by axial and cis-positioned equatorial F atoms.

The cationic cyclo­metallated iridium(III) complex [Ir(C9H7N2)2(C12H8N2)](PF6) has been synthesized and crystallized by the inter-diffusion method. It contains an unknown number of solvent mol­ecules and has a different space-group symmetry (C2/c) structure than its solvatomorph (P21/c).

The new copper(II) complex [CuLCl2]2, where L is a product of Schiff base condensation between methyl­amine and 2-pyridine­carbaldehyde, is built of discrete centrosymmetric dimers.

The asymmetric unit of the title compound contains two independent mol­ecules, consisting of perimidine and phenol units, which are linked through an N—H⋯O hydrogen bond. Intra­molecular O—H⋯N hydrogen bonds are observed in both independent mol­ecules.

The title compound, 1-(2,5-di­meth­oxy­phen­yl)-2,2,6,6-tetra­methyl­piperidine, was synthesized as a side-product during the synthesis of the inter­mediate, methyl 3,6-dimeth­oxy-2-(2-meth­oxy-2-oxoeth­yl)benzoate, necessary for the total synthesis of the isocoumarin 5,8-dimeth­oxy-3-methyl-1H-isochromen-1-one.

The dihedral angle between the two aromatic rings of the title compound is 64.12 (14)°. The crystal structure is stabilized by a short Cl⋯H contact, C—Cl⋯π and van der Waals inter­actions.

The title complex, Cu(L)2 or [Cu(C15HF10O2)2], comprising one copper ion and two fully fluorinated ligands (L−), was crystallized with 3,4-ethyl­ene­dioxy­thio­phene (EDOT, C6H6O2S) as a guest mol­ecule to give in a di­chloro­methane solution a unique co-crystal, Cu(L)2·3C6H6O2S.

Who’s Who in Payments – Complete Overview of Key Payment Providers encompasses key trends in the payments industry.

An intuitive method is presented for detecting pseudosymmetries in Z' > 1 cases as a complement to well-proven strategies already available in the literature. It is based in the simple idea that the mid-points between equivalent atoms in symmetrically related mol­ecules are disposed according to simple well-known patterns, which are easily recognizable by optical inspection. A number of Z' = 4 cases in the literature are analyzed, which allows some of the potentialities of the method to be revealed.

The crystal structure of tri­phenyl­methanol, C19H16O, has been redetermined using data collected at 295 and 153 K, and is compared to the model published by Ferguson et al. over 25 years ago [Ferguson et al. (1992). Acta Cryst. C48, 1272–1275] and that published by Serrano-González et al., using neutron and X-ray diffraction data [Serrano-González et al. (1999). J. Phys. Chem. B, 103, 6215–6223]. As predicted by these authors, the hy­droxy groups are involved in weak inter­molecular hydrogen bonds in the crystal, forming tetra­hedral tetra­­mers based on the two independent mol­ecules in the asymmetric unit, one of which is placed on the threefold symmetry axis of the Roverline{3} space group. However, the reliable determination of the hy­droxy H-atom positions is difficult to achieve, for two reasons. Firstly, a positional disorder affects the full asymmetric unit, which is split over two sets of positions, with occupancy factors of ca 0.74 and 0.26. Secondly, all hy­droxy H atoms are further disordered, either by symmetry, or through a positional disorder in the case of parts placed in general positions. We show that the correct description of the hydrogen-bonding scheme is possible only if diffraction data are collected at low temperature. The pro­chiral character of the hydrogen-bonded tetra­meric supra­molecular clusters leads to enanti­omorphic three-dimensional graphs in each tetra­mer. The crystal is thus a racemic mixture of supS and supR motifs, consistent with the centro­symmetric nature of the Roverline{3} space group.

The enanti­opure monopyrrolidine derivative (2S)-methyl (Z)-5-(2-tert-but­oxy-1-cyano-2-oxo­ethyl­idene)pyrrolidine-2-carboxyl­ate, C13H18N2O4, (1), represents a potential ligand and an attractive inter­mediate for the synthesis of chiral metal com­plexes. At the mol­ecular level, the com­pound features an intra­molecular N—H⋯O hydrogen bond; neighbouring mol­ecules inter­act via N—H⋯N contacts to form chains along [100]. Due to its elemental com­position, resonant scattering of the target com­pound is entirely insignificant for diffraction experiments with Mo Kα and small even for Cu Kα radiation. A preliminary study with the harder radiation type confirmed the chiral space group and the suitability of the single crystal chosen; as expected, the results concerning the absolute structure remained com­pletely inconclusive. A second data collection with the longer wavelength gave satisfactory quality indicators for the correct handedness of the mol­ecule, albeit with high standard uncertainties. The absolute configuration has been assessed independently: CD spectra for both enanti­omers of the target mol­ecule were calculated and the spectrum for the S-configured stereoisomer was in agreement with the experiment. The Cotton effect of (1) may be ascribed to π–π* transitions from HOMO to LUMO and from HOMO to LUMO+1. As both independent techniques agree with respect to the handedness of the target mol­ecule, the absolute structure may be assigned with a high degree of confidence.

During investigations of the formation of hydrated magnesium carbonates, a sample of the previously unknown magnesium carbonate hexa­hydrate (MgCO3·6H2O) was synthesized in an aqueous solution at 273.15 K. The crystal structure consists of edge-linked isolated pairs of Mg(CO3)(H2O)4 octa­hedra and noncoordinating water mol­ecules, and exhibits similarities to NiCO3·5.5H2O (hellyerite). The recorded X-ray diffraction pattern and the Raman spectra confirmed the formation of a new phase and its transformation to magnesium carbonate trihydrate (MgCO3·3H2O) at room temperature.

An efficient synthesis of 1-aryl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-ones, involving the diazo­tization of 3-amino-4-aryl­amino-1H-isochromen-1-ones in weakly acidic solution, has been developed and the spectroscopic characterization and crystal structures of four examples are reported. The mol­ecules of 1-phenyl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H9N3O2, (I), are linked into sheets by a combination of C—H⋯N and C—H⋯O hydrogen bonds, while the structures of 1-(2-methyl­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C16H11N3O2, (II), and 1-(3-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H8ClN3O2, (III), each contain just one hydrogen bond which links the mol­ecules into simple chains, which are further linked into sheets by π-stacking inter­actions in (II) but not in (III). In the structure of 1-(4-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, (IV), isomeric with (III), a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds links the mol­ecules into sheets. When com­pound (II) was exposed to a strong acid in methanol, qu­anti­tative conversion occurred to give the ring-opened transesterification product methyl 2-[4-hy­droxy-1-(2-methyl­phen­yl)-1H-1,2,3-triazol-5-yl]benzoate, C17H15N3O3, (V), where the mol­ecules are linked by paired O—H⋯O hydrogen bonds to form centrosymmetric dimers.
