Impact of Covid-19 on Cold Chain Tracking and Monitoring Systems Market Research Report 2020, Thrives the Global Industry Growth at Impressive CAGR...

Its always interesting to hear backstories on our favorite television programs or films and the Today Show is no different.

Recently, former Today co-anchor Katie Couric revealed how she got wind that ultra right-wing conservative Ann Coulter was scheduled to be interviewed by Ann Curry, and the steps Couric immediately took.

Its well known at this point that Ann Curry was basically booted from Today, with the most popular rumor being that her co-anchor, Matt Lauer, had allegedly requested that Curry be shifted from the show.

To make matters worse, Good Morning Americas ratings were skyrocketing, sending Todays producers and higher-ups into a panic.

The New York Times reported in 2013 about an anonymous assessment by Todays senior staffers and talent after Currys dismissal. One person wrote, our sense of family is broken, and another said, Matt is being blamed, and some in our audience see Savannah as the younger replacement wife.

Gayle King asked Ann Curry on CBS This Morning in 2018 if she would agree that Matt Lauer had derailed her career. Curry replied, You should ask someone else, Im not the one to ask about that I dont know what was all behind it. I do know that it hurt like hell.

In an interview with the Everything Iconic with Danny Pellegrino podcast this week, Couric addressed how often she stays in touch with her former colleague.

I havent seen her, Couric said. Once in a while, Ill run into her at things, but I think shes working on a PBS show or something. You know, I always liked Ann, but we werent really very close friends. So I havent kept up with her, but I hope shes doing well, I really do.

Pellegrino asked Couric if she ever switches on the Today Show on weekday mornings.

No, I dont, shhhh, Couric said laughing. Not really, not too much. . . I really get most of my news on my telephone. I think Ive just changed the way I consume news and information.

In her interview with Pellegrino, the topic of Courics 2002 infamous interview with Ann Coulter came up.

Courics response to Coulters name? Oh God, she was awful.

Couric continued, I find her to be a fascinating character, a lot of it is bravado and theater. I think shes probably extremely conservative, but I also feel like her whole schtick is . . . shes a provocateur.

The mother of two thanked Pellegrino for bringing her testy conversation with Coulter up, as she wants to include it in her memoir, which she is hoping to publish by 2021.

Im writing my memoir and that reminds me, I definitely have to write about that interview, which was just so intense. . . Some people think she ate me alive and some people think that I ate her alive.

The New York City resident then dropped the bombshell that it was actually Ann Curry who was slated to interview the contentious political personality that day.

Couric doesnt explain why she insisted on handling the conversation. But its most likely because Coulter, in the book she was promoting, Slander: Liberal Lies About the American Right, labeled Couric as the affable Eva Braun of morning TV and Couric wanted the author to explain what she meant by the stinging remark.

The former Today host perhaps also wanted to spare Ann Curry from what would have probably been a bloodbath of an interview with only Currys bones figuratively left afterward.

Ann Curry was scheduled to do that interview, Couric told Pellegrino, and I told the woman who books authors [on Today], because Ann Coulter had a book coming out, I said, No no no no no, I need to do that interview.'

Katie Couric on How She Spared Ann Curry From an Interview with 'Provocateur' Ann Coulter - Showbiz Cheat Sheet

As you can well imagine, my mailbox has been overflowing with questions about the coronavirus from precisely ZERO readers. So I decided to write my own questions. I know this is what youwouldbe asking if you were not standing in line, outside, 6 feet apart, to purchase a quart of milk.

What do you think of the medias coverage of the Wuhan virus?

Its like a nonstop War of the Worlds broadcast, which in 1938 panicked more than a million Americans into believing Martians had landed in New Jersey, sending people fleeing to the mountains, loading their shotguns and barricading their homes. And that was a single radio broadcast!

Today we have nearly all of media which I notice are doing fantastically well during the crisis terrifying the public about an apparently indestructible, omnipresent virus.

You dont think the China virus is as dangerous as they say?

Well, it is a virus capable of eliminating all human life, which would be bad, but notallbad because then youd never have to see another TV commercial with some company saying they consider you family.

So you think its safe to start lifting the stay-at-home orders?

Of course. I ask again: What was the purpose of telling everyone to stay home? Arent we all Wuhan-free now? More than 90 percent of the country has been self-quarantining for more than a month. Either we had it and didnt know it, or never had it at all. But in any eventwe dont have it now.

Or was that whole stay-at-home mandate just for fun?

What about threats of a resurgence?

Luckily the hospitals are half-empty, waiting for the gusher of coronavirus patients.

So we do nothing?

No, not at all, but now that 90 percent of us are Wuhan-free, these are the only things we need to do:

1) A real immigration moratorium, like this country had from 1924 to 1965. (Id also recommend that the other 49 states shut down flights from New York, but Ill leave that up to them);

2) Concentrate all protections on the elderly/immunocompromised;

3) No more handshaking, and liberal use of surgical masks in confined spaces.

Other than that, WERE DONE NOW.

But we know virtually nothing about this virus: why it kills, what stops it, how its transmitted.

Actually, we know one very important thing: By total serendipity, the Wuhan virus mostly kills people over the age of 70. Nearly 80 percent of all coronavirus deaths in the U.S. are of people over 70 years old.

What about Italy?

About 80 percent of the dead were over 70.

That sounds a little callous.

Not at all. Its a stroke of good luck! Wed be lucky if the virus targetedanyspecific group the nearsighted, left-handers, golfers because that would allow us to concentrate protections on that one group.

But its doubly good news because the Wuhan targets people who are mostly out of the workforce anyway. And we already have their names and addresses! How about the feds send a box of masks along with Social Security checks every month?

How will you get Democratic governors to go along with that?

Liberals can triple down on all their fascist stuff as long as its limited to the vulnerable.

Over 65? You need a note from the governor to leave your home!

Fine! But let the rest of us get back to work.

Why havent they done this already?

Because that wouldnt have the effect of wrecking the economy before the election.

Apart from the election, why would the media want to impoverish the nation?

1) Reporting on disasters is fun!

2) Their ratings are terrific and, of course,theyrestill being paid.

3) Liberals enjoy controlling people, especially with enragingly nonsensical rules.

I thought Trump was the authoritarian!

No, hes the lazy, narcissistic blowhard.Liberalsare the authoritarians.

The shutdown is airport security for the whole country. Nineteen Muslim immigrants flew planes into the World Trade Center and the Pentagon, and suddenly little old ladies from Oklahoma had to be goosed at airports.We have to be safe!

A horrible Chinese virus sweeps the planet, which is devastating to older people but virtually harmless to the young and the entire country has to be shut down.We have to be safe!

What about polls showing a majority of Americans want to keep the restrictions in place?

The media have frightened gullible suburban woman into a state of hysteria. (Talk about whipping up your ignorant base!) Kids could basically mainline coronavirus and theyd be fine. But soccer moms dont want their kids going back to school.

Whether its rational or not, people arent going to go out like they used to.

My entire life, liberals have said, Dont like abortion? Dont have one. Dont like pornography? Dont look at it. And so on.

I say: Dont want to leave your home? Dont leave your home!

So you recommend going out again?

Sure, whats the worst that could happen? Sure, you could die, but you probably wont.

Ann Coulter: Q & A on the Wuhan Virus - Breitbart

When the bizarre world of quantum physics where a "cat" can be both alive and dead, and particles a galaxy apart are connected is merged with computer technology, the result is unprecedented power to anyone who masters this technology first.

There is an obvious dark side. Imagine a world where online bank accounts could be easily hacked into and robbed. But this power can also be turned to good, allowing new drugs to be designed with unprecedented speed to cure disease. To prepare for such a future, many countries are investing billions to unlock the potential of what is called quantum computing. With an eye toward the future, a group of researchers at Fermilab,a particle physics laboratory in Batavia, Ill., has worked with high-school teachers to develop a program to train their students in this emerging field.

This program, called "Quantum Computing as a High School Module," was developed in collaboration with young students in mind. But it's also a perfect diversion for science enthusiasts of any age who suddenly have a lot of time on their hands.

This online training course introduces students to quantum concepts, including superposition, qubits, encryption, and many others. These additional concepts include quantum measurement, entanglement and teleportation; students will also learn and how to use quantum computers to prevent hacking. The course is also appropriate for community college or undergraduate students in areas outside of physics, such as computer science, engineering or mathematics, as well as a science literate public. One of the course's teachers, Ranbel Sun wrote, "It was great to work with a couple of America's smartest researchers to make sure that the science was right. Combining their knowledge and our teaching experience, we have developed an understandable learning program which bridges the gap between popular media and college textbooks."

Quantum computing uses the principles of quantum physics, which were developed in the early 1900s. Quantum physics describes the tiny realm of atoms, where the laws of nature seem to be very different from the world we can see. In this microcosm, electrons and particles of light called photons simultaneously act as both waves and particles a seeming absurdity, but one that is well accepted among scientists.

This non-intuitive quantum behavior has been exploited to develop powerful technologies, like the lasers and transistors that form the backbone of our technological society. Nobel Prize winning physicist Richard Feynman was the first to suggest that computers could be built to directly exploit the laws of quantum mechanics. If successful, these quantum computers could solve incredibly important and difficult problems that are too complex for even the most powerful modern supercomputers to solve. Last year, Google used a quantum computer called Sycamore to solve a problem thought to be virtually unsolvable by conventional computers; a calculation that would take the most powerful supercomputers 10,000 years to finish was solved in just 200 seconds by Sycamore.

The familiar computer on your desk uses a vast array of objects called bits to operate. Bits are basically simple switches that can be either on or off, which is mathematically equivalent to ones and zeros. Quantum computers rely on qubits, which can simultaneously be both on and off at the same time. This peculiar feature is common in the quantum world and is called superposition: being in two states at once. Researcher Ciaran Hughes said, "The quantum world is very different from the familiar one, which leads to opportunities not available using classical computers."

In 1994, Peter Shor invented an algorithm that revealed the power of quantum computing. His algorithm would allow quantum computers to factorize a number enormously faster than any classically known algorithm. Factorizing numbers is important because the encryption system used by computers to communicate securely relies on the mathematics of prime numbers. Prime numbers are numbers that are divisible only by one and themselves.

In a standard encryption algorithm, two very large prime numbers are multiplied together, resulting in an even larger number. The key to breaking the security code is to take the large number and find the two prime numbers that were multiplied together to make it. Finding these prime numbers is extremely hard for ordinary computers and can take centuries to accomplish.

However, using Shor's quantum algorithm, finding these prime factors is much easier. A working quantum computer would make our standard method of encryption no longer secure, resulting in the need for new encryption methods. Fermilab researcher Jessica Turner said, "Quantum computing is a very new way of thinking and will be revolutionary, but only if we can develop programmers with quantum intuition."

Obviously, any nation state or individual who is able to crack encryption codes will have a huge information advantage. The competition to develop working quantum computers is the new space race.

Quantum computing has the potential to overturn how computers securely communicate: from health care, to financial services and online security. Like it or not, the future is quantum computing. To fully reap the rewards of this quantum revolution requires a quantum fluent workforce. This new program is a very helpful step towards that goal.

The researchers have made their training program freely available.

TV Devs BBC iPlayer and FX on Hulu

Halfway through episode two of Devs, there is a scene that caused me first to gasp, and then to swear out loud. A genuine WTF moment. If this is what I think it is, I thought, it is breathtakingly audacious. And so it turns out. The show is intelligent, beautiful and ambitious, and to aid in your viewing pleasure, this spoiler-free review introduces some of the cool science it explores.

Alex Garlands eight-part seriesopens with protagonists Lilyand Sergei, who live in a gorgeous apartment in San Francisco. Like their real-world counterparts, people who work atFacebook orGoogle, the pair take the shuttle bus to work.

They work at Amaya, a powerful but secretive technology company hidden among the redwoods. Looming over the trees is a massive, creepy statue of a girl: the Amaya the company is named for.

We see the company tag line asLily and Sergei get off the bus: Your quantum future. Is it just athrow-away tag, or should we think about what that line means more precisely?

Sergei, we learn, works on artificial intelligence algorithms. At the start of the show, he gets some time with the boss, Forest, todemonstrate the project he has been working on. He has managed to model the behaviour of a nematode worm. His team has simulated the worm by recreating all 302 of its neurons and digitally wiring them up. This is basically the WormBot project, an attempt to recreate a life form completely in digital code. The complete map of the connections between the 302 neurons of the nematode waspublished in 2019.

We dont yet have the processing power to recreate theseconnections dynamically in a computer, but when we do, it will be interesting to consider if the resulting digital worm, a complete replica of an organic creature, should be considered alive.

We dont know if Sergeis simulation is alive, but it is so good, he can accurately predict the behaviour of the organic original, a real worm it is apparently simulating, up to 10 seconds in thefuture. This is what I like about Garlands stuff: the show has only just started and we have already got some really deep questions about scientific research that is actually happening.

Sergei then invokes the many-worlds interpretation of quantum mechanics conceived by Hugh Everett. Although Forest dismisses this idea, it is worth getting yourhead around it because the show comes back to it. Adherents say that the maths of quantum physics means the universe isrepeatedly splitting into different versions, creating a vast multiverse of possible outcomes.

At the core of Amaya is the ultrasecretive section where thedevelopers work. No one outside the devs team knows what it is developing, but we suspect it must be something with quantum computers. I wondered whether the devssection is trying to do with the 86 billion neurons of thehuman brain what Sergei has been doing with the 302 neurons of the nematode.

We start to find out when Sergei is selected for a role in devs. He must first pass a vetting process (he is asked if he is religious, a question that makes sense later) and then he is granted access to the devs compound sealed by alead Faraday cage, gold mesh andan unbroken vacuum.

Inside is a quantum computer more powerful than any currently in existence. How many qubits does it run, asks Sergei, looking inawe at the thing (it is beautiful, abit like the machines being developed by Google and IBM). Anumber that it is meaningless to state, says Forest. As a reference point, the best quantum computers currently manage around 50 qubits, or quantum bits. We can only assume that Forest has solved the problem ofdecoherence when external interference such as heat or electromagnetic fields cause qubits to lose their quantum properties and created a quantum computer with fantasticprocessing power.

So what are the devs using it for? Sergei is asked to guess, and then left to work it out for himself from gazing at the code. He figures it out before we do. Then comes that WTF moment. To say any more will give away the surprise. Yet as someone remarks, the world is deterministic, but with this machine we are gaining magical powers. Devs has its flaws, but it is energising and exciting to see TV this thoughtful: it cast a spell on me.

Devs: Here's the real science behind the quantum computing TV show - New Scientist News

A discovery that long eluded physicists has been detected in a laboratory at Princeton. A team of physicists detected superconducting currents the flow of electrons without wasting energy along the exterior edge of a superconducting material. The finding was published May 1 in the journal Science.

Researchers at Princeton have discovered superconducting currents traveling along the outer edges of a superconductor with topological properties, suggesting a route to topological superconductivity that could be useful in future quantum computers. The superconductivity is represented by the black center of the diagram indicating no resistance to the current flow. The jagged pattern indicates the oscillation of the supercurrent, which varies with the strength of an applied magnetic field.

The superconductor that the researchers studied is also a topological semi-metal, a material that comes with its own unusual electronic properties. The finding suggests ways to unlock a new era of "topological superconductivity" that could have value for quantum computing.

"To our knowledge, this is the first observation of an edge supercurrent in any superconductor," said Nai Phuan Ong, Princeton's Eugene Higgins Professor of Physics and the senior author on the study.Learn more about topological materials in thisessayby Ong.

"Our motivating question was, what happens when the interior of the material is not an insulator but a superconductor?" Ong said. "What novel features arise when superconductivity occurs in a topological material?"

Although conventional superconductors already enjoy widespread usage in magnetic resonance imaging (MRI) and long-distance transmission lines, new types of superconductivity could unleash the ability to move beyond the limitations of our familiar technologies.

Researchers at Princeton and elsewhere have been exploring the connections between superconductivity and topological insulators materials whose non-conformist electronic behaviors were the subject of the 2016 Nobel Prize in Physics for F. Duncan Haldane, Princeton's Sherman Fairchild University Professor of Physics.

Topological insulators are crystals that have an insulating interior and a conducting surface, like a brownie wrapped in tin foil. In conducting materials, electrons can hop from atom to atom, allowing electric current to flow. Insulators are materials in which the electrons are stuck and cannot move. Yet curiously, topological insulators allow the movement of electrons on their surface but not in their interior.

To explore superconductivity in topological materials, the researchers turned to a crystalline material called molybdenum ditelluride, which has topological properties and is also a superconductor once the temperature dips below a frigid 100 milliKelvin, which is -459 degrees Fahrenheit.

"Most of the experiments done so far have involved trying to 'inject' superconductivity into topological materials by putting the one material in close proximity to the other," said Stephan Kim, a graduate student in electrical engineering, who conducted many of the experiments. "What is different about our measurement is we did not inject superconductivity and yet we were able to show the signatures of edge states."

Stephan Kim, a graduate student in the Department of Electrical Engineering, conducted experiments demonstrating supercurrents in a topological material.

The team first grew crystals in the laboratory and then cooled them down to a temperature where superconductivity occurs. They then applied a weak magnetic field while measuring the current flow through the crystal. They observed that a quantity called the critical current displays oscillations, which appear as a saw-tooth pattern, as the magnetic field is increased.

Both the height of the oscillations and the frequency of the oscillations fit with predictions of how these fluctuations arise from the quantum behavior of electrons confined to the edges of the materials.

"When we finished the data analysis for the first sample, I looked at my computer screen and could not believe my eyes, the oscillations we observed were just so beautiful and yet so mysterious," said Wudi Wang, who as first author led the study and earned his Ph.D. in physics from Princeton in 2019. "It's like a puzzle that started to reveal itself and is waiting to be solved. Later, as we collected more data from different samples, I was surprisedat how perfectly the data fit together."

Researchers have long known that superconductivity arises when electrons, which normally move about randomly, bind into twos to form Cooper pairs, which in a sense dance to the same beat. "A rough analogy is a billion couples executing the same tightly scripted dance choreography," Ong said.

The script the electrons are following is called the superconductor's wave function, which may be regarded roughly as a ribbon stretched along the length of the superconducting wire, Ong said. A slight twist of the wave function compels all Cooper pairs in a long wire to move with the same velocity as a "superfluid" in other words acting like a single collection rather than like individual particles that flows without producing heating.

If there are no twists along the ribbon, Ong said, the Cooper pairs are stationary and no current flows. If the researchers expose the superconductor to a weak magnetic field, this adds an additional contribution to the twisting that the researchers call the magnetic flux, which, for very small particles such as electrons, follows the rules of quantum mechanics.

The researchers anticipated that these two contributors to the number of twists, the superfluid velocity and the magnetic flux, work together to maintain the number of twists as an exact integer, a whole number such as 2, 3 or 4 rather than a 3.2 or a 3.7. They predicted that as the magnetic flux increases smoothly, the superfluid velocity would increase in a saw-tooth pattern as the superfluid velocity adjusts to cancel the extra .2 or add .3 to get an exact number of twists.

Wudi Wang, the first author on the study, led the study and conducted many of the experiments. He earned his Ph.D. in physics from Princeton in 2019.

The team measured the superfluid current as they varied the magnetic flux and found that indeed the saw-tooth pattern was visible.

In molybdenum ditelluride and other so-called Weyl semimetals, this Cooper-pairing of electrons in the bulk appears to induce a similar pairing on the edges.

The researchers noted that the reason why the edge supercurrent remains independent of the bulk supercurrent is currently not well understood. Ong compared the electrons moving collectively, also called condensates, to puddles of liquid.

"From classical expectations, one would expect two fluid puddles that are in direct contact to merge into one," Ong said. "Yet the experiment shows that the edge condensates remain distinct from that in the bulk of the crystal."

The research team speculates that the mechanism that keeps the two condensates from mixing is the topological protection inherited from the protected edge states in molybdenum ditelluride. The group hopes to apply the same experimental technique to search for edge supercurrents in other unconventional superconductors.

"There are probably scores of them out there," Ong said.

New Princeton study takes superconductivity to the edge - Princeton University

The coronavirus pandemic has rapidly transformed education. Now that the reality of being away from peers for sustained periods of time is setting in, the isolation that comes with social distancing is dramatically reducing students motivation. Professors, meanwhile, face a different set of challenges, chiefly figuring out ways to keep students motivated. The reality is that students did not sign up for online learning and no matter how hard a professor tries, they will not be able to motivate all students.

Fear that students will completely disengage and/or drop out of college altogether is strong. Educators do know, however, that they need to be resilient and to continue engaging students no matter how effective their efforts are.

For students, maintaining a schedule and a workspace are crucial, but the unknown horizon of when universities will reopen makes all of this more difficult. Students who are used to working in various environments (the library, their department, cafs around town) are now spending full days in their parents homes. Adjusting to getting work done in my bedroom has been difficult, says Solenne Smith, a junior in American Universitys College of Arts and Sciences, now working from Branford, Connecticut, who usually finishes assignments from coffee shops on campus. In these busy spaces where students congregate on their laptops, there is a camaraderie that many are now trying to re-create in virtual study groups.

Faculty realize that to keep pupils focused, they must take a more active role. This requires more frequent contacts with students, multiple e-mailing, and, for the first time, I have allowed students to call me at home, says Steven Taylor, an associate professor in the Department of Government at American Universitys School of Public Affairs. He urges students to refrain from taking study breaks, like binge-watching videos and shows, as these tend to add further distractions. I do not attach much importance to taking breaks from working. Breaks become habitual and can lead to a lack of focus, Taylor says.

Educators appreciate these new challenges, which is especially assuring to students struggling to meet deadlines. Nobody expects us to be on top of our game right now, says one sophomore at George Washington University. To that end, many universities are providing the option to take classes pass/fail. American, like many other universities such as George Washington and Johns Hopkins, has loosened the rules around pass/fail, which takes pressure off students. But it might also make it harder to stay motivated. It makes me not want to do anything because if I get a C or an A, I still pass, so why put in extra work, says Emily Lynch, a junior at American Universitys School of Communication.

Overall, the onset of the pandemic has made some college students more appreciative of the time they have spent on campus. Op-eds published in The Eagle, American Universitys student newspaper, have expressed gratitude for students time on campus. The sophomore at GWU agrees: I dont know that motivation will increase but rather we will be grateful for the things we had before the pandemic.

Indeed, the prospect of returning to campus is a motivating factor in and of itself. It will make me appreciate the college experience and remind me to make the most out of the semesters I have left, says Advika Rajapakse, a junior at Johns Hopkins University.

George Washington Universitys Counseling and Psychological Services (CAPS) provides virtual walk-ins for students in need of mental-health support. They continue to hold regular business hours from 8:30 a.m. to 5 p.m. Virtual walk-ins are like regular meetings with a therapist except they are done through programs like Skype. JHU also provides online mental-health support for students. JHU goes a step further than GW in that they also provide phone numbers to call for counseling services. While neither university has an infinite capacity for how many student cases they can handle, each approach is innovative and best addresses the needs of as many students as possible.

American Universitys webpage reads, It is not uncommon to feel sad, isolated, stressed, or anxious during this time. While this has been a time of significant change including, but not limited to, disruption to academic and social routines, we remain committed to supporting our students, staff, and faculty through our virtual services and resources. Additionally, we recognize that the COVID-19 pandemic has greatly impacted certain communities, with an increase in xenophobia, racial aggression, economic deprivation, stigma, and barriers to appropriate resources. American Universitys commitment to supporting students was made clear in the fact that they list and recognize the potential problems.

GW also expressed concerns regarding xenophobia and racial aggression in its campus response: We know that the COVID-19 originated from Wuhan, Hubei Province, China and as a result, members of the GW community from China may be experiencing increased stress at this time. Students, faculty, and staff who are from China or of Chinese descent or others from a diverse background are valued members of our community.

In a letter to students and faculty, JHU President Ronald J. Daniels wrote, I have been deeply moved by the resiliency, determination, and almost fathomless reserves of grace with which Johns Hopkinseach of youis showing up, forging ahead, and getting through this historic moment as one community.

Daniels has taken the most optimistic approach to motivating students by singing the praises of the JHU community. GWs and Americans statements are objective, fact-based, and offering of support.

What has kept me motivated through the coronavirus pandemic is keeping a structured routine. I build into that schedule things beyond the virtual classroom that keep me energized: listening to the music of Lon, a Swedish indie-pop/soul singer; regular exercise; moving around and relocating from one workspace to another. Even for a workaholic like me, its easy to lose concentration. At the end of the day, the most distracting thing is the uncertainty about the fall semester. We are nearing the end of this period, which we coped with because it was temporary, but the prospect of a more permanent transformation of college education is frightening. The challenge going forward is staying motivated when you dont know what college life will be like.

SUPPORT THE PROSPECT

Staying Motivated When Schools Online - The American Prospect

(Just kidding, that sh*ts impossible right now) Pxhere | Photo courtesy Me, sleeping peacefully, through two noon deadlines.

Its a quiet Wednesday night. By Friday, I have a paper, two projects, an exam and probably an existential crisis to get done. There are currently about 64 projects I have started in my apartment and not finished and Im currently contemplating buying a third laundry hamper rather than doing a single load of laundry.

At this exact moment, there are about 200 different productive things I could be doing, but I currently only have the mental capacity to mentally order which establishments have the best quality Sprite (personally, I think McDonalds Sprite is the crispiest, and if you dont know what I mean we cant be friends anymore).

Finding enough motivation to just leave my room is hard enough, let alone finishing all the toughest assignments that seem to come near semesters-end. True story: I picked a pillow up off the floor and put it on my bed yesterday and rewarded myself with a two-hour nap. So the chances of me finishing that project on survey analysis? About the same as the likelihood that Emma Watson finally answers my DMs on Instagram (shes busy alright, it could still happen).

I know Im not the only one struggling here. Ive seen fellow students up until four in the morning doing homework when the will to get something accomplished finally graces them. A personal favorite is the daily videos an NDSU student posts on Snapchat of them screaming into a pillow while doing biology.

If students are struggling, Id have to imagine professors are struggling too. The only thing worse than writing an essay on the American dream riddled with ramblings reminiscent of a sleep-deprived toddler is reading thirty essays on the American dream riddled with ramblings reminiscent of a sleep-deprived toddler. I feel for you, Rooth.

Students and teachers alike have it rough right now. So the best thing anybody can do is be understanding.

A big shout-out to all the students assisting one another, helping with homework questions and being patient when your friend who promised to send you their lecture notes (me, probably) and is sending them over a few days late. And a bigger-shout out to the professors who recognize that this semester should not be about grades.

NDSU extending the pass-fail deadline is awesome. An institution that recognizes that just passing a class in the midst of a nationwide shutdown is accomplishment enough is surprisingly refreshing. Add to that, professors who have eased up on the workload for the rest of the semester and I might just find religion through all of this, because angels are real.

On the other hand, to the professors who are requiring the same level of excellence from students trying to piece together your twenty part assignment from that one corner of their garage that has Wifi, not to ruin my argument with the colloquial or anything, but could you please chill out? People have more important things to worry about, like a literal global emergency, than your proud title of professionally indifferent jerk.

I understand that years of poor student reviews and that 1 out of 5 on Rate-My-Professor is really getting to you, but many students are going through worse than a personal crisis of character, and a little understanding at this time is all that is needed.

However, that same level of understanding needs to be given not only to others but to ourselves too. While I dont personally recommend fully succumbing to the dark side of laziness; lush with its riches of wearing the same outfit for an entire week, eating handfuls of dry cereal and watching hours of Tiktoks via Facebook because you hate yourself, there are some things to be said for taking things one step at a time.

This whole lockdown started with people, in a haze of their capitalist and entitled upbringing, insisting that all this free time was the perfect opportunity to start a business, learn a new skill, or finally write that book (catch my book out this summer, Realizing No Amount of Time Will Make You the Next Hemingway: A Series of Personal Essays).

Instead, most people realized that being without friends, structure and reliable access to toilet paper isnt conducive to changing your life. It turns out that dream of being a hermit we used to have as middle schoolers in the age of Tumblr, not going to school or work, avoiding people at all costs and having 24-hour access to Rick and Morty is only a dream if your goal is to have B.O. and vitamin C deficiency, not if you want any semblance of happiness.

Theres not a lot of advice I can give on this topic. This isnt one of those one-size-fits-all formulas to stay motivated that are floating around the internet right now. Staying motivated isnt concern number one, personally, its like concern number 43, right in between planning my imaginary Tokyo Disney vacation and wondering if they sell any grilled cheese costumes small enough to fit my cat.

Students: all I can say is that Im here for you in spirit. May the will to get something done come at least once a week and may it be long enough to get you through that one assignment thats worth 30 percent of your grade.

Professors: have pity on us students. Some of us are stronger than others, but some of us are pathetic, shame gremlins that struggle to come out of our Pringles and Dr. Pepper stupor without constant social interaction. Please be gentle with us.

With any luck, well get through this together, not as new and better people, but as worn and sorrowful comrades that have been through something horribly embarrassing that we wont ever want to talk about again. And hey, if you didnt drink a bottle of bleach, start the hashtag #NorthDakotaSmart about ending a lockdown, or protest your right to go get your beard professionally trimmed. In the grand scheme of things, youre not doing so bad, right?

Association between work schedules and motivation for lifestyle change in workers with overweight or obesity: a cross-sectional study in Japan.

BMJ Open. 2020 Apr 30;10(4):e033000

Authors: Tanikawa Y, Kimachi M, Ishikawa M, Hisada T, Fukuhara S, Yamamoto Y

Abstract OBJECTIVE: To investigate the association between work schedules and motivation for behavioural change of lifestyle, based on the transtheoretical model (TTM) in workers with overweight or obesity. DESIGN: A cross-sectional observational study. SETTING: A healthcare examination centre in Japan. PARTICIPANTS: Between April 2014 and March 2016, we recruited 9243 participants who underwent healthcare examination and met the inclusion criteria, namely, age 20-65 years, body mass index (BMI) 25 kg/m2 and full-time workers. EXPOSURE: Night and shift (night/shift) workers were compared with daytime workers in terms of motivation for behavioural change. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was action and maintenance stages of change (SOC) for lifestyle in TTM. In a subgroup analysis, we investigated interactions between characteristics, including age, sex, BMI, current smoking, alcohol habits, hours of sleep and working hours. RESULTS: Overall, 1390 participants (15.0%) were night/shift workers; night/shift workers were younger (median age (IQR): 46 (40-54) vs 43 (37-52) years) and the proportion of men was lesser (75.4 vs 60.9%) compared with daytime workers. The numbers of daytime and night/shift workers in the action and maintenance SOC were 2113 (26.9%) and 309 (22.2%), respectively. Compared with daytime workers, night/shift workers were less likely to demonstrate action and maintenance SOC (adjusted OR (AOR): 0.85, 95% CI: 0.74 to 0.98). In a subgroup analysis that included only those with long working hours (10 hours/day), results revealed a strong inverse association between night/shift work and action and maintenance SOC (AOR: 0.65, 95% CI: 0.48 to 0.86). A significant interaction was observed between long working hours and night/shift work (P for interaction=0.04). CONCLUSIONS: In workers with overweight or obesity, a night/shift work schedule was associated with a lower motivation for behavioural change in lifestyle, and the association was strengthened in those with long working hours.

In March, when a state stay-at-home order forced educators to began teaching students remotely, Chatham Central teacher Laurie Paige started Paige Academy at her home.

Paige, a 20-year veteran history teacher of who last year was honored as Chatham Countys Teacher of the Year, established a plan and a routine for her family ringing a bell first thing in the morning to signal to her two children, 3rd and 9th graders, the school day was beginning. During mornings, she focuses on helping her younger child complete his school material by lunch, so she could focus on her high school students in the afternoon all the while keeping a close eye on her 9th graders progress in his four classes.

That lasted two weeks, Paige said. Then it just became survival of the fittest at that point. It just wasnt realistic.

Teachers across the state have been working from home, educating students from a distance since N.C. Gov. Roy Coopers order to close schools because of the COVID-19 pandemic in March.

Two Chatham County teachers shared their experiences with the News + Record Paige and Olivia Metcalf, who is in her second year teaching at Margaret Pollard Middle School. How they are spending their days now demonstrate just some of the ways teachers in Chatham County are working to not only continue educating their students, but also provide the social and emotional support their students and parents need right now.

To read the perspective of fourth grade teacher Susan Loflin of Bennett School, click here.

Metcalf has been teaching her students remotely from the Wake County home she shares with her French bulldog, Luna. Metcalf is a self-proclaimed early morning person. Each school day, she wakes up early to check email and figure out plans for the day. She creates a checklist of meetings, which include online classes and required school staff meetings, and reviews the tracking of communications with her students.

I keep track of the kids Ive talked to, Metcalf said. And I work to connect with kids who may have challenges in communicating.

Metcalf said that she works about the same amount of time teaching as when she was in the classroom, but she spends a lot more time on planning. She provides work for students two weeks in advance and schedules check-ins with students and provides question and answer periods for them.

On the other hand, Paige has discovered that she has had to adapt her work time to be available to her high school students. She originally set up office hours from 10 to 11 a.m., but found her students were not always available at that time.

That was very unrealistic, Paige said. A lot of students are working a lot of hours [at jobs] during the day. The kids who work at Food Lion are working almost full-time. A lot of my students are working and working excessively.

As a result, she has been receiving a lot of late-night emails and messages from her students. She said that some days she doesnt even turn off her computer until 1 a.m.

Most are doing their school work at night, she said. So Ive readjusted my schedule to be available later in the day. If a student asks a question, I want to be able to answer it. Weve had to adjust our time-frames to be more flexible to our students needs.

Keeping in touch

For these teachers, their biggest priorities are communicating with their students and parents.

Paige starts each day sending a Remind, a phone application for school communication, to her students alerting them to what assignments they need to be working on. She ends each day with another message recapping what they should have gotten done or accomplished for the day.

She records her lessons for each chapter for the students to use followed by assignments to ensure they have mastered the material. For each one of her four classes, she schedules at least one virtual class on Zoom, a video conferencing tool. Since many of her students are working during the day, she will sometimes hold those Zooms in the evening when her students are available.

Most of my day is spent trying to keep up with my students and communicating with parents, Paige said. [If I saw my students everyday in the classroom] they would been in tune and keeping up with work. Now if they dont show to a zoom or turn in assignments, I know I need to reach out. Something has happened, something is different. Im constantly working, letting the kids know Im there for them and support them.

Metcalf estimates that about 15 percent of her students dont have access to internet service. For those students, she created paper versions of her lessons. She said its the same content, but maybe not as engaging as online. Even with the digital gap, Metcalf noted that those students are still finding ways to be able to communicate with her, whether by email or by phone.

Im in constant communication with kids and parents, she said. Its very hard to go from seeing your students five days a week to now. They are missing the social aspect, they dont get to socialize with classmates. Theyre having a hard time at home. Its different, odd and feels weird. I miss seeing them so when I get to see them on Zoom or talk on the phone, its so nice to have that. Being able to communicate, using personalized communication, thats really valuable to me.

Challenges

For Paige, the biggest challenge is keeping her students motivated, especially her seniors. Schools were originally informed that students who were seniors would be graded using a pass/fail model, meaning that if they had passing grades as of March 13, they would pass their classes. If they were failing as of that date, they would be able to pull up their grades during virtual learning to receive a passing grade. Though the state provided updated guidance last Friday that students could have the option to use number grades instead of pass/fail, up until now, keeping those students engaged has been an uphill battle.

My biggest challenge is keeping the students motivated to do the work, Paige said. Giving them reasons to continue, especially the seniors. I just keep encouraging them to work for the AP exam. Its really, really hard.

Im feeling a lot of pressure, Metcalf said. These kids are going into high school next year and I want them to be prepared and successful for their future. Going from teaching in a classroom to teaching behind a screen is really difficult.

Metcalf said that at this point in the year, her students would typically be working on end-of-year projects and presentations. As a result, shes has had to adjust what shes teaching. She said shes fortunate to have a fellow Social Studies teacher, 20-plus year teaching veteran Dawn Streets, to collaborate with to find new ways to support her students education. She also thinks that as a new teacher, she may be better suited to adjust.

I think being kinda new to this, I like to do things in new different and creative ways, Metcalf said. I get to experiment, using digital tools, while trying to bring same energy to motivate my students. Its a learning process for me, but its nice because the kids are learning too. No matter what level of experience, were all learning too.

Resilience

Though in unchartered and challenging waters, both teachers expressed an unwavering support for their students and parents.

Never in my 20 years have I worked as hard and as many hours as I have in the past month., Paige said. Before everything was done hands-on and is now being done virtually. Its like building a plane as were flying it.

I feel like teachers really are working harder than probably ever have for their students, she continued. Its easy to think, Oh theyre just sitting at home, but I know from my colleagues and the teachers of my children how much work they are doing and the dedication and support is amazing. Educators across the country are all coming up with innovative ideas for their students, not just in providing educational support, but social and emotional support.

I know its hard for parents who are used to dropping off their kids, Metcalf said. Who now have to help their children to navigate this new way of learning. Im always someone you can talk to whether you need help or just want to talk to someone outside your home.

A parent called me yesterday, thanking me for instilling such a good work ethic in my child, Metcalf continued. Knowing were appreciated goes such a long way.

Everybody is trying to do everything they can to meet the needs of the students, Paige said. Many are sad, they are at home, they cant do all the things they want to do. Its a lot of change for young people.

I have seen that students are resilient and accepting of change, Paige said. As much of a disruption that it is for me, the students have adapted. Our students really can overcome more than I thought and more than they thought. If you had told me before Im not sure I would have believed it, but the kids are doing it. I believe they are learning, mastering the material, just in a very different way than I would have anticipated.
