The proton-conducting material (NH4)4H2(SeO4)3 is examined to check whether its conductivity spectra are sensitive to subtle changes in the crystal structure and proton dynamics caused by external pressure. The AC conductivity was measured using impedance spectroscopy, in the frequency range from 100 Hz to 1 MHz, at temperatures 260 K < T < 400 K and pressures 0.1 MPa < p < 500 MPa. On the basis of the impedance spectra, carefully analyzed at different thermodynamic conditions, the p–T phase diagram of the crystal is constructed. It is found to be linear in the pressure range of the experiment, with the pressure coefficient value dTs/dp = −0.023 K MPa−1. The hydrostatic pressure effect on proton conductivity is also presented and discussed. Measurements of the electrical conductivity versus time were performed at a selected temperature T = 352.3 K and at pressures 0.1 MPa < p < 360 MPa. At fixed thermodynamic conditions (p = 302 MPa, T = 352.3 K), the sluggish solid–solid transformation from low conducting to superionic phase was induced. It is established that the kinetics of this transformation can be described by the Avrami model with an effective Avrami index value of about 4, which corresponds to the classical value associated with the homogeneous nucleation and three-dimensional growth of a new phase.

World Wrestling Entertainment held their annual Wrestlemania show last weekend in Northern California, the culmination of another year's worth of spectacle. According to the company, it was their highest grossing event of all-time, drawing $12.6 million, with an official attendance placing it fifth on their list of all-time crowds for the event. The show was headlined by former UFC Heavyweight Champion Brock Lesnar going up against up-and-coming star (and a relative of Dwayne "The Rock" Johnson) Roman Reigns.

WWE Network

It comes at a time when the company has embarked on a new way of making money: their over-the-top online programming provider, the WWE Network, where fans can pay $9.99 a month to see programming including what formerly used to cost $45 for most shows and $60 for Wrestlemania. They're one year in now on gambling that enough fans will want the Network that it will ultimately make them more money in the long-term, despite losing that pay-per-view revenue. Wall Street doesn't appear to be buying it — after announcing the day after Wrestlemania that they'd hit 1.3 million subscribers, WWE's stock took a significant loss.

"The point is not whether it's real or if it's staged. The point is, are you entertained by it, or not?" former WWE announcer Jim Ross told KPCC in an interview. WWE is looking for more fans to be entertained enough to plunk down $9.99 for all the pro wrestling content they want.

NXT

They're also in a transitional period with their audiences. They've launched a new show that's only on the Network called "NXT," turning their minor league into a program targeting hardcore pro wrestling fans with a different style of show than the more family-targeted "Raw" and "Smackdown." It's also where they groom potential future stars, many of whom seem to break the mold of some of the traditional stars on WWE's main roster.

They're signing up talent that's been getting buzz on the independent circuits, trying to create their own underground movement that hopefully spells money, and taking the NXT brand on tour for the first time. On the Raw after Wrestlemania, several NXT stars made their debut on the main roster. That follows a sell-out crowd (albeit at a smaller 5,000 seat venue) on the Friday night before Wrestlemania for a non-televised NXT show.

Give Divas a chance

WWE also faces cultural forces pushing them in new directions, including a difference in how society deals with gender. When WWE executive Stephanie McMahon, daughter of the famed Vince McMahon, tweeted in support of Patricia Arquette's speech calling for greater equality for women at the Academy Awards, one of their own wrestlers, AJ Lee, responded by publicly calling Stephanie McMahon out on Twitter for not promoting the women in her own company equally and paying them less than the male stars.

AJ tweet 2

Of course, the women in the company aren't given the same prominence as the men in part because it's felt that they won't make the company as much money. Still, it forced WWE's hand and Stephanie McMahon and the company as a whole publicly embraced the idea of giving the women (who WWE brands as "divas") a chance with the Give Divas A Chance movement (and accompanying trending hashtag).

What's next

The women have been promoted nearly equal to the men in that underground NXT league, but only time will tell if it continues to trickle upward. Wrestlemania didn't seem to show huge promise of that happening, with the one women's match of the show only getting a few minutes in the ring. However, the show also included a high-profile storyline with UFC female fighter and champion Ronda Rousey alongside the Rock, going up against Stephanie McMahon and Triple H, so there appears to be the room for women in prominent positions when they have the right storyline.

Whether WWE is able to wade through these forces of change to make more money — and perhaps regain some of the cultural currency that they've lost since becoming a monopoly and purchasing their top competition in 2001 — remains to be seen. They've stayed relatively steady despite a challenge from UFC, which many see as being what pro wrestling would be like if WWE didn't present fictional  They'll have to hope that giving new stars, including "divas," a chance will take them to another level.

To ensure the Comprehensive Everglades Restoration Plan (CERP) is responsive to changing environmental conditions like climate change and sea-level rise, as well as to changes in water management, a new report by the National Academies of Sciences, Engineering, and Medicine calls for a re-examination of the program’s original restoration goals and recommends a forward-looking, systemwide analysis of Everglades restoration outcomes across a range of scenarios.

As we welcome a new year and a new decade, we can make one prediction with certainty -- profound change lies ahead.

More than 9.6 million children — or 13 percent of all children in the U.S. — live in families with annual incomes below the poverty line, according to data from 2015. As closures and restrictions related to COVID-19 begin to impact the U.S. economy, it’s clear many more families will be receiving fewer paychecks and less income in the coming months, putting more children at risk of falling below the poverty line.

I know these Presidential debates aren’t debates in the historical sense.  Regardless, I’m looking forward to seeing how both men do on a topic of immense complexity.  Is Mitt Romney going to be more forthcoming about what tax deductions he’d want cut to keep his tax reform plan from ballooning the deficit?  Will President Obama  give more detail about how he would improve the economy, short of a government stimulus that could never get through a GOP Congress?

I’ll be live tweeting during the debate.  Join me @AirTalk #debates.

After nearly two months of “safer at home” during the COVID-19 outbreak, the state of California appears to be taking its first steps towards reopening businesses and restarting the economy.

Governor Gavin Newsom announced on Monday during the daily press briefing he has held since the start of the outbreak that California will be entering the first phase of its four-stage plan and allowing certain retail businesses like bookstores, music stores, sporting goods stores and florists to reopen for pickup as early as Friday. Manufacturing and logistics can start in the retail supply chain again as well. There are also local control measures in effect that allow certain municipalities to decide themselves whether to move farther ahead in the process and reopen certain things like restaurant dining rooms, though anyone deciding to do so would have to submit “containment plans” to the state. Two cities in Orange County, which has been involved in a back-and-forth with Sacramento over his order last week closing all state and local beaches in OC, have been cleared to reopen their beaches after they submitted plans to the state last week for how they’d reopen the beaches while safely controlling crowds.

Had the 2020 MLB season started at the end of March like it was scheduled to, at this point we’d be starting to see divisions shape up, star pitchers and position players separating themselves from the rest of the league and a first look at who this year’s contenders and pretenders really would be. Sadly, the COVID-19 outbreak forced the league to postpone the start of the season, and now the question has become if there will be a season, not when. 

Not to be dragged down by the idea of no baseball, Wall Street Journal sports writer Jared Diamond took a recent proposal the league floated for an abbreviated 2020 campaign and gamed out how that might look in real life. The league’s idea would do away with the National and American Leagues and divide all 30 MLB teams into three divisions of 10 teams separated by region, and those teams would play in empty stadiums and only against other teams in their geographic division in the interests of reducing travel. But how viable is this, really? And what other considerations would the league and players union have to take with regards to testing and protocol for what happens if someone were to contract COVID-19? Is there a world where baseball still happens this year?

Today on AirTalk, Jared Diamond joins the Triple Play of Larry Mantle, Nick Roman and A Martinez to talk about what a shortened 2020 MLB season might look like, which teams stand to win and lose the most from the realignment and what other precautions the league would have to take against the spread of COVID-19.

The coronavirus pandemic has brought out the good side of many Americans, but certainly not all Americans. Officials say that fraud related to COVID-19 — like hoarding equipment, price gouging and hawking fake treatments — are spreading as the country wrestles with the outbreak.

"It's a perfect ecosystem for somebody like a fraudster to operate in," said Craig Carpenito, the U.S. attorney for New Jersey and the head of the Justice Department's COVID-19 price gouging and hoarding task force.

"People want to believe that there's a magic pill that they can take or that if they buy a certain kind of mask or a certain kind of protective gear that it's going to protect them and their families," he said. "That creates opportunities for the types of people that prey upon scared people. They prey upon their fear."

A month ago, Attorney General William Barr instructed federal prosecutors around the country to aggressively investigate and prosecute scams and other crimes related to the COVID-19 pandemic. He also created the price gouging and hoarding task force and put Carpenito in charge of it.

From that perch, Carpenito has one of the best views of virus-related crime nationwide.

"Instead of seeing that tremendous support from all aspects of society, we're still seeing that sliver, that that dark underbelly, that small percentage of folks who instead of putting the interests of the country and support for those medical professionals that are putting themselves at risk in the forefront, they're finding ways to try and take advantage of this situation and illegally profiteer from it," he said. "And it's despicable."

The most prevalent kind of fraud that federal authorities are seeing at this point, he and others say, is tied to personal protective equipment like N95 masks, gloves or face shields.

In one notable case, prosecutors brought charges against a Georgia man, Christopher Parris, for allegedly trying to sell $750 million worth of masks and other protective equipment to the Department of Veterans Affairs but with a sizable advance payment.

The problem, prosecutors say, is the masks and other items didn't exist, at least not in the quantities Parris was offering.

Steven Merrill, the head of the FBI's financial crimes section, says the bureau refers to these sorts of operations as advance-fee schemes.

"We're getting many complaints that different entities are entering into these agreements, paying money upfront, sometimes hundreds of millions of dollars, and may or may not get any masks or other PPE ordered at all," Merrill said. "So our guidance to the public is to please be wary of these frauds and solicitations."

Other problems, such as hoarding and price gouging, can arise even when the medical gear does exist.

The FBI is trying to identify individuals who are stockpiling protective equipment and trying to sell it at exorbitant markups, sometimes 40 to 70 times the value, Merrill said.

A few weeks ago, the FBI seized nearly 1 million respirator masks, gloves and other medical gear from a Brooklyn man who was allegedly stockpiling them and selling them to nurses and doctors at what officials say was around a 700% markup.

The man, Baruch Feldheim, has been charged with lying to the FBI about price gouging. He's also been charged with allegedly assaulting a federal officer after he coughed on agents and claimed he had COVID-19.

The confiscated items, meanwhile, have been distributed to medical workers in the New York area.

Carpenito said the Justice Department has more than 100 investigations open into price gouging. It has hundreds more, he said, into other crimes tied to the pandemic, including fake treatments and cures.

In one case out of California, prosecutors charged a man who was allegedly soliciting large investments for what he claimed was a cure for COVID-19.

"He was doing so by broadcasting this scheme via, notably, YouTube, where had thousands of hits and views," Merrill said.

In a separate case out of Florida last week, the Justice Department got a court order to stop a Florida church from selling on its website an industrial bleach that was being marketed as a miracle treatment for the virus.

To be clear, the Centers for Disease Control and Prevention says there is no cure at this point for the virus.

More than a month into this crisis, there's no sense COVID-related crime is going to slow down.

In fact, Carpenito and Merrill say that with the massive $2 trillion economic relief package beginning to be doled out, they expect to see even more fraud in the weeks and months ahead.

"What we're worried about is that not only do we have these existing conditions, but we are awaiting — like everybody in the country — the arrival of $2 trillion to hit the streets," Merrill said. "And anytime there's that much money out there, you can just multiply the amount of frauds that are going to take place. So we're preparing for many more complaints to come in and new schemes to arrive on a daily basis."

What will happen on college campuses in the fall? It's a big question for families, students and the schools themselves.

A lot of what happens depends on factors outside the control of individual schools: Will there be more testing? Contact tracing? Enough physical space for distancing? Will the coronavirus have a second wave? Will any given state allow campuses to reopen?

For all of these questions, it's really too early to know the answers. But one thing is clear: Life, and learning for the nation's 20 million students in higher education, will be different.

"I don't think there's any scenario under which it's business as usual on American college campuses in the fall," says Nicholas Christakis, a sociologist and physician at Yale University.

So why are so many colleges announcing they will be back on campus in the fall?

In many cases, it's because they're still trying to woo students. A survey of college presidents found their most pressing concern right now is summer and fall enrollment. Even elite schools, typically more stable when it comes to enrollment, have reportedly been tapping their waitlists.

In the midst of all this uncertainty, it's worth looking at some of the ideas out there. With the help of Joshua Kim and Edward J. Maloney, professors and authors of the book Learning Innovation and the Future of Higher Education, here are some potential scenarios for reopening colleges and universities:

All virtual

Perhaps the most obvious option for the fall is to continue doing what they've been doing this spring. Colleges have signaled that they're planning for this option — even if it's a last resort. California State University, Fullerton, was one of the first to announce publicly it was planning for a fall semester online.

"Obviously we want to resume in-person teaching as soon as possible, but we also need to make sure that we're safe," says Ellen Treanor, who helps lead strategic communication at the school. Treanor says it made a lot of sense to assume the school would start online. "What would be the easier way to transition? It would be easier to transition beginning virtually and then transitioning in person," she said. "The faculty [needs] to be prepared."

With virtual classes, students can remain at home, although some colleges are exploring bringing them back to campus, where they could use the school's Wi-Fi to take online classes.

Delayed start

A delay in the semester would allow a school to wait it out until it was safer to reopen. One option is to push back a month or two, starting in October or November. Another idea is to push a normal start to January. In that case, the spring semester would become the fall semester, and potentially students could stay on campus through next summer to make up the spring semester. Boston University floated a version of this January start date when it announced a number of plans it was exploring.

One downside to a late start is what students will do in the meantime, especially those who don't have financial stability and rely on campus or the university to be a safe and stable home.

Some online, some face-to-face

This would be a hybrid model, with a combination of virtual and in-person classes. It may be a good choice for campuses that don't have enough classrooms to allow adjusting face-to-face teaching to the requirements of social distancing.

"You might have some of the larger classes being taught online simply because it's harder to imagine a 150- or 350-person classroom," says Maloney, who leads the Center for New Designs in Learning and Scholarship at Georgetown University. "So you might see that class split up into multiple sections." For large, entry-level classes, colleges may have a lecture component online and then meet in smaller groups in person.

"The hybrid model doesn't have to just be about modality," Maloney says. "It can be, but it could also be about fundamentally rethinking what the core structure has been for those large classes."

Of course, shifting larger classes online may not be enough, by itself, to alleviate the health concerns of having students on campus. Early research from Cornell University found that eliminating such classes didn't lessen student interactions with each other.

Shortened blocks

In block scheduling, students take just one course at a time for a shorter duration, typically three or four weeks. Colorado College, a liberal arts school south of Denver, has been using this model for 50 years. The college adopted this style of classes because "it allows [students] to take a deep dive and really focus in unique ways on the single subject," says Alan Townsend, the provost there. In a typical year, the school offers eight blocks.

In addition to its intensity, block scheduling is attractive right now because it allows flexibility. Colleges that use it have the opportunity to change the way classes look every three weeks — since there are multiple start and stop points. (With a semester, you have only a single start and then, often 16 weeks later, an end.)

"It's easier for us to now think creatively for next year," Townsend says. "Different students can make different choices. That's really hard to do with a semester-based system, but the blocks allow us to do that a little bit more flexibly."

The school is also entertaining the idea of sending faculty abroad to teach a block for international students who might not be able to enter the U.S, or adding summer blocks to give students even more opportunities to take classes.

Only some on campus

Some colleges have suggested bringing only freshmen back to campus and having upperclassmen either delay their start, or be online and remote.

The idea centers on research that shows just how important a student's first year of college is as a predictor of graduation. Adapting to campus can be a challenge, so this would allow first-year students to get comfortable and have extra support on campus.

Since upperclassmen are already familiar with how campus and classes work, the theory goes, they can more easily adapt to an online environment. Other versions of this approach would have students who have housing needs come back to campus first, and then, over time, phase in other groups of students.

All these options seek to keep the population density of the campus lower while still maintaining some face-to-face interactions.

On campus, with some changes

Social distancing, improved testing and contact tracing could help colleges reopen their campuses.

"Every school is trying to figure out a way to have students come back and do whatever we can while also protecting public health," says Learning Innovation co-author Joshua Kim, director of online programs and strategy at Dartmouth College.

"At the same time, we know that, however that works, things will be different. It's probably unlikely that we'll be able to cram students together in large, packed lecture halls or put doubles and triples in residence halls or have big events."

To follow social distancing, professors are measuring their classrooms, calculating how many students could fit in the space if they were 6 feet apart. Deans are planning out how students could enter and exit the classrooms safely.

But it's not just the classrooms that pose a challenge. For residential colleges, it's the dorms.

"Whether or not students are actually learning in the classroom, it's incredibly important for them to have an on-campus experience," Maloney says. So schools are thinking about how they can spread their students out, putting them in places where they normally wouldn't go.

Some ideas include housing students in offices that aren't being used, local hotel rooms or off-campus housing. Institutions are also reimagining campus events, like freshman orientation, since it's unlikely hundreds of students will be in a packed auditorium.

"Rethinking how we do everything we do at a university is part of the process," Maloney says.

Fragments of crushed rock released into the ocean during oil and gas exploration can physically bury organisms that live on the seafloor, accounting for 55% of offshore drilling???s environmental impact, according to a recent study. To allow more informed marine policy decisions, this physical impact must be recognised alongside the impact of chemicals released in drilling waste.

Researchers have developed a method to identify the parts that contribute the most to a product's greenhouse gas (GHG) emissions and evaluate alternative design solutions. When applied to a LCD television, it showed that GHG emissions could be cut by 36 per cent by using alternative parts to those currently used.

A new study by European researchers highlights the important contribution of greenhouse gases (GHGs) other than carbon dioxide to climate change and suggests policy measures to help reduce their impact. The study provides improved estimates of the current GHG balance of Europe, taking nitrous oxide and methane into account.

Traditional services also have some very strong propositions, like digital workplace, engineering services. Some of the demand for that is intact and it is only getting accelerated.

Particles from vehicle emissions are not the only traffic-related factor that causes deterioration of air quality in cities. Suspended road dust, caused by studded tyres, road salt and sand used in winter, may be at least as important in contributing to mortality rates, according to a new study in Stockholm, which suggests that these coarse particles should be controlled separately to fine particles.

The future challenge is to develop analytic strengths that span the organisation and not just areas of expertise.

The importance of predicting future threats to the areas connecting biodiversity hotspots when planning conversation projects is highlighted in a new study. Using Costa Rican forest as a case study, researchers compared forward-looking planning methods to those that focus exclusively on current threats and found the forward-looking approaches to be more effective and reliable.

Up to 90% of consumed drugs enter the environment. This may have negative effects on wildlife, especially when the drugs take long periods to break down. This study assessed the breakdown of sulphonamides — a class of antibacterials — in samples from two rivers in Poland. The results showed that sulphamethoxazole, a common veterinary antibiotic, was the most persistent and that various factors inhibit degradation, including low temperatures, heavy metal pollution and low pH.
