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.

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 title com­pound, tetra­ethyl­ammonium tetra­thio­rhenate, [(C2H5)4N][ReS4], has, at room temperature, a disordered structure in the space group P63mc (Z = 2, α-phase). A phase transition to the monoclinic space group P21 (Z = 2, γ-phase) at 285 K leads to a pseudo-merohedral twin. The high deviation from the hexa­gonal metric causes split reflections. However, the different orientations could not be separated, but were integrated using a large integration box. Rapid cooling to 110–170 K produces a metastable β-phase (P63, Z = 18) in addition to the γ-phase. All crystals of the β-phase are contaminated with the γ-phase. Additionally, the crystals of the β-phase are merohedrally twinned. In contrast to the α-phase, the β- and γ-phases do not show disorder.

Marvel Comics held a press conference this week announcing details about "Secret Wars," a company-wide comic book crossover that they promise will change everything.

Promises of change in comics often don't amount to much, but here's why this one just might, with Marvel teasing that it will produce a whole new world for its characters.

"We see this as putting an endcap to decades of stories and starting a new era," said Marvel Editor-in-Chief Axel Alonso. "And when you see the scope of the event, you see what we're doing, what we're willing to do, this is a place where we're going to be bringing new pieces onto the board and taking old pieces off. You guys will be yelling and screaming, you'll be loving, hating, and in equal measure."

Reboot history

Rival DC Comics has always been quick to have stories designed to streamline their history, with the "Crisis on Infinite Earths" being the most famous one — a story that destroyed the DC Comics universe of the time, birthing a new timeline that gave us the versions of DC's heroes we know today. Several minor and major reboots followed, with the biggest since then being 2011's New 52 (and a tease of another one with this April's "Convergence").

Meanwhile, Marvel still refers back to stories from their early days, beginning with the first issue of "Marvel Comics" in 1939, and more so since the launch of "Fantastic Four" and the interlinked Marvel Universe in the 1960s, led by Stan Lee and Jack Kirby.

Marvel previously launched a line of comics meant to offer a fresh vision of the Marvel characters called Ultimate Comics, but now the worlds of those characters and the traditional Marvel universe are getting combined thanks to "Secret Wars."

"The Ultimate Universe, the Marvel Universe, they're going to smash together," said Alonso. "This is the Marvel Universe moving forward."

"We've never done anything like this, ever," said Marvel senior vice president and executive editor Tom Brevoort. "And what we're going to do to top it, I don't know. Hopefully that will be somebody else's problem."

The stories leading to "Secret Wars," and what is Battleworld?

The story that's been built up so far has to do with different universes colliding into each other — and in the first issue of "Secret Wars," the Marvel and Ultimate Earths collide, with the heroes of those worlds unable to stop it. What's left behind is what Marvel is calling "Battleworld," a patchwork planet with different parts of it inhabited by the characters from different famous Marvel crossovers of the past (you can see some of those past titles in the slideshow above).

Marvel released this video to help you visualize what exactly Battleworld is:

Battleworld video

See a map of Battleworld here, showing the different worlds made up of old storylines to be explored in "Secret Wars" (and click to enlarge):

Brevoort described Battleworld as "The little melting pot in which the new Marvel Universe will be created" after the Marvel and Ultimate versions of Earth are destroyed. He said that Battleworld is what Marvel is going to be "during, through and after" the beginning of "Secret Wars."

"Once you hit 'Secret Wars' 1, there is no Marvel Universe. There is no Ultimate Universe. All there is is Battleworld, and a whole lot of empty void," Brevoort said.

"Every single piece of this world is a building block for the Marvel Universe moving forward," Alonso said. "None of these stories are Elseworlds, or What Ifs, or alternative reality stories. They aren't set in the past or the future. They're not set in an alternate reality. They're set in the reality of the Marvel Universe."

It's also a story that uses an old name — the original "Secret Wars" involved an alien taking heroes from Earth and forcing them into battle for the fate of the universe. It remains unclear if the villain from that crossover will play a role here.

Why is Marvel rebooting?

Observers were quick to speculate on some of the behind-the-scenes reasons for the change. Combining the Ultimate Universe with the traditional Marvel Universe would let them incorporate the half-black, half-Latino Spider-Man from the Ultimate line that grabbed headlines a few years ago. It would let them do something different with characters like the X-Men and the Fantastic Four, who have been a flashpoint for controversy due to Fox retaining rights in perpetuity to any films based on those characters.

It also opens the door to a longtime comic book trope: Bringing back to life the dead.

"If we were to want to resurrect Gwen Stacy, this would be the place to do it, wouldn't it?" Alonso said.

What do creators and fans think about "Secret Wars"?

Speaking of the death of Gwen Stacy, the writer who pulled the trigger on killing her, Gerry Conway, tells Newsarama that he's on board.

"I think like with any idea, the execution will matter more than the idea itself. The idea of a reset is, by itself, not a bad idea," Conway said.

One who's less on board with it: longtime Spider-Man artist John Romita.

"My guess is new fans will be okay with it, and old fans will grumble," Romita told Newsarama. "I’m not a businessman, but I do know that comic companies, for almost 100 years now, do whatever they can for shock value. They grab attention. Personally, I hate all the goofy things they do. When I was there, I used to fight stuff like this. But you can’t stop them."

Current Marvel writers have been sworn to secrecy about what happens once "Secret Wars" is done:

The lack of certainty about what this all means has led fans to wildly speculate, as well as poke fun at what might happen:

Fan tweet 2

It's a story that's been years in the making.

"Every single time we've done an event, we've always had to be mindful of 'Secret Wars,' and we've had to make decisions based on the fact that we knew that 'Secret Wars' was headed our way," Alonso said.

Brevoort said that Hickman proposed a version of "Secret Wars" years ago, but that vision has since become significantly larger.

"It sounds like typical Stan lee hyperbole — and there's nothing wrong with typical Stan Lee hyperbole — but it is difficult to imagine something that would be larger in scope, in scale, than what we are doing with 'Secret Wars,'" Brevoort said.

That father of the modern Marvel comics world, Stan Lee, tells Newsarama that the reboot is "probably good."

"Anything they do that’s unexpected and different usually captures the attention of the fans," Lee said. "It sounds intriguing to me."

Lee also tells Newsarama that if he were to do it all again, he'd do it basically the same, describing what he did as "the right way to go, and maybe sometimes, even the perfect way to go."

"I liked making the Fantastic Four superheroes without a secret identity. I liked the tragedy of Spider-Man’s origin, the ‘with great power, there must also come great responsibility.’ I thought it was the right way of doing things at the time. And I still like what I’ve done," Lee said. "I can’t think, off the top of my head, of anything I’d really want to change."

What does "Secret Wars" mean for fans?

More details are promised in the weeks to come, with a free preview issue being released on Free Comic Book Day, May 2. While fans wait, they may want to heed the wait-and-see approach advocated by Conway and famed "Thor" artist Walt Simonson.

"Maybe this is coming back out of my old geology days, but I try not to have instant reactions to things and say, ‘Oh my God! That’s terrible!’" Simonson told Newsarama. "My basic reaction is usually ‘let’s see the evidence in the field.’ Let’s come back in a year and see what we’ve got. That will tell the story.”

And for those who say that Marvel is ruining their childhood by messing with the history of their favorite characters, Conway tells Newsarama:

"I would say to them, no, your childhood is still your childhood. There’s a point to be made, and it’s a universal one: We have to see that there’s a difference between what people do today, and what they did yesterday. Yesterday still exists, those stories still exist. Now someone else is getting a chance at a new childhood. And that’s nice."

Public school employees can take their required annual training to spot child abuse or neglect online, California State Superintendent of Public Instruction Tom Torlakson announced Monday.

“Nothing is more important than the safety of our students,” Torlakson said in a written statement. “The new online training lessons will help school employees carry out their responsibilities to protect children and take action if they suspect abuse or neglect.”

A new California law requires school employees, including teachers, teacher aides, and substitute teachers, to show proof to their employers that they’ve taken the training.

“We were hearing anecdotally that there may have been suspicions of abuse and neglect that was not always reported and we wanted to do something about that issue,” said Stephanie Papas, a California Department of Education consultant.

Recent high-profile cases, such as that of former Miramonte Elementary teacher Mark Berndt, revealed that school employees failed to report allegations of abuse. Los Angeles Unified agreed to pay a record $140 million to settle claims filed by one group of students in the case and $30 million to a second group. Berndt is serving a 25-year sentence after pleading no contest to the charges of committing lewd acts on children.

Papas, who helped create the new two-hour online training, said the course will help employees tell if a child has been hurt from abuse or from an accident, for example.

“We have photos that are examples of, say, a welt that is in the shape of a belt buckle or a slap on a child’s cheek that’s left a hand imprint,” she said.

In-person trainings are more effective, she said, but they’re more expensive than online trainings. That pushed the Department of Education to provide the free online training for school districts still under budget constraints.

She said current employees have until this fall to show their school districts proof that they’ve taken the training.

National Science Foundation (NSF)-funded researchers from North Carolina State and Elon universities have developed a technique that allows them to remotely control the movement of soft robots, lock them into position for as long as needed and later reconfigure the robots into new shapes. The technique relies on light and magnetic fields. "By engineering the properties of the material, we can control the soft robot's movement remotely; we can get it to hold a given shape; we can then return the robot to its original shape or further modify its movement; and we can do this repeatedly. All of those things are valuable, in terms of this technology's utility in biomedical or aerospace applications," says Joe Tracy, a professor of materials science and engineering at NC State and corresponding author of a paper on the work. In experimental testing, the researchers demonstrated that the soft robots could be used to form "grabbers" for lifting and transporting objects. The soft robots could also be used as cantilevers or folded into "flowers" with petals that bend in different directions. "We are not limited to binary configurations, such as a grabber being either open or closed," says Jessica Liu, first author of the paper and a Ph.D. student at NC State. "We can control the light to ensure that a robot will hold its shape at any point."
