Panic buying, ignoring safety measures: The social psychology of crises

Credit: Will Kirk / Johns Hopkins University
Times of crisis can bring out the best in people. It can also reveal the strangest parts of human nature.
While restaurants in six states are offering free toilet paper to those in need in response to the barren toilet paper shelves in many local grocery stores, U.S. Today reports that a  in Newport, Oregon, issued an urgent request for residents to stop calling 911 when they run out of toilet paper. "You will survive without our assistance," the department stated.
Meanwhile, as the New York Times reports young people are continuing to travel despite restrictions and state and local governments are closing businesses to prevent people from congregating in public, groups of older adults, including an enclave of retirees in Florida and the parents of one New Yorker writer, are largely resisting the very social distancing behaviors that may protect their health.
Why?
"This outbreak is a classic example of a social dilemma," says Stephen Drigotas, a teaching professor and co-director of undergraduate studies in the Department of Psychological and Brain Sciences at Johns Hopkins. He is an expert in social psychology, and he says he'll likely draw from these  for material to include in his introductory course.
In the case of people panicking about toilet paper shortages, there are two phenomena in play, Drigotas explains.
First, panic buying during a pandemic is a classic example of a social dilemma: an inherent conflict between a person's individual self-interest and the good of the group as a whole. In this case, stockpiling goods is an example of the commons dilemma, which is based on 19th-century accounts of farmers who overgrazed public land set aside for their use by the government. Farmers could bring as much livestock to graze as they wanted, but many farmers came too often or with too many animals, and soon the land was stripped, requiring a season of no grazing in order to regrow and replenish.
"For an individual farmer, the dilemma was that they wanted to maximize the amount of grazing for their herd and ensure their livestock were all well-fed, but if too many farmers acted that way, the resource would be depleted for everybody," Drigotas explains.
During this outbreak of COVID-19, he says, common resources like food, toilet paper, and other essentials can become depleted if people don't show restraint.
"The problem occurs when people start to think that they're the ones sacrificing or missing out and they see other people benefiting," Drigotas says. "It inherently changes their mindset, and they'll actually start to feel that they're being taken advantage of. It causes people to react—panic might be a strong word—but it changes their motivation to become more selfish or overestimate what they need. In this case, it's toilet paper, of all things."
Another element at play is called the law of scarcity, which relates to how consumers think about goods that are in limited supply or available for a limited time, Drigotas says. Marketers will often use that sense of urgency to inspire people to make purchases they otherwise wouldn't. People are especially susceptible to the law of scarcity when they don't put much cognitive energy into their decision making, such as during late-night infomercials, or during a stressful, last-minute trip to the grocery store.
The challenge here, Drigotas explains, is inspiring people to resist the influence of the law of scarcity on their thinking and practice restraint in their purchasing.
"The more messages that get out there about how we should behave and how we should respond to this dilemma of the coronavirus outbreak, the more we'll understand that practicing restraint is the right thing to do," Drigotas says. "Moreover, if you can see evidence of other people showing restraint, people will be more likely to say yes, we can all work together in the face of this crisis."
Important groups of people may be ignoring these key messages about restraint, however. Business Insider reports that millennials are "snapping up" inexpensive flights despite travel warnings from the U.S. State Department and Centers for Disease Control and Prevention.
Drigotas says a fair amount of these behaviors can be chalked up to the recklessness of youth, but there may be another phenomenon at work here. "The probability is that if you're young, you aren't likely to experience poor outcomes from contracting this disease," he says. "I suspect that as we start to see more evidence of how this disease affects people and younger people start knowing people who get infected, they will start to show a little more restraint in their actions."
But paradoxically,  have also emerged indicating that many baby boomers are unwilling to cancel cruises or practice social distancing measures despite being at higher risk of developing severe illness if they contract COVID-19.
"Humans aren't good at doing probability estimates," Drigotas says. "There may be a mindset within this population that contracting COVID-19 is high consequence but low probability. For , the estimate would be that contracting COVID-19 is high probability but low consequence. This could explain why these two groups might eschew social distancing measures."
Drigotas cautions that it's not clear yet how statistically relevant these reports about baby boomer and millennial behaviors are—there's still much to learn and study, he says. He plans to continue to monitor the outbreak and look for evidence of the principles of  at play, but he, like his Johns Hopkins colleagues, will be doing it from the comfort—and safety—of his home.

Electric jolt to carbon makes better water purifier

Nagoya University scientists have developed a one-step fabrication process that improves the ability of nanocarbons to remove toxic heavy metal ions from water. The findings, published in the journal ACS Applied Nano Materials, could aid efforts to improve universal access to clean water.
Various nanocarbons are being studied and used for purifying  and wastewater by adsorbing dyes, gases,  and toxic  ions. These nanocarbons can adsorb heavy metal ions, like lead and mercury, onto their surfaces through molecular attraction forces. But this attraction is weak, and so they aren't very efficient adsorbents on their own.
To improve adsorption, scientists are considering adding molecules to the nanocarbons, like , that form stronger chemical bonds with heavy metals. They are also trying to find ways to use all available surfaces on nanocarbons for metal ion adsorption, including the surfaces of their inner pores. This would enhance their capacity to adsorb more metal ions at a time.
Materials scientist Nagahiro Saito of Nagoya University's Institute of Innovation for Future Society and colleagues developed a new method for synthesizing an "amino-modified nanocarbon" that more efficiently adsorbs several heavy metal ions compared to conventional methods.
They mixed phenol, as a source of carbon, with a compound called APTES, as a source of amino groups. This mixture was placed in a glass chamber and exposed to a , creating a plasma in liquid. The method they used, called "solution plasma process," was maintained for 20 minutes. Black precipitates of amino-modified carbons formed and were collected, washed and dried.
A variety of tests showed that amino groups had evenly distributed over the nanocarbon surface, including into its slit-like pores.
"Our single-step process facilitates the bonding of amino groups on both outer and inner surfaces of the porous nanocarbon," says Saito. "This drastically increased their adsorption capacity compared to a nanocarbon on its own."
They put the amino-modified nanocarbons through ten cycles of adsorbing copper, zinc and cadmium metal ions, washing them between each cycle. Although the capacity to adsorb metal ions decreased with repetitive cycles, the reduction was small, making them relatively stable for repetitive use.
Finally, the team compared their amino-modified nanocarbons with five others synthesized by conventional methods. Their nanocarbon had the highest adsorption capacity for the metal ions tested, indicating there are more amino groups on their nanocarbon than the others.
"Our process could help reduce the costs of water purification and bring us closer to achieving universal and equitable access to safe and affordable drinking water for all by 2030," says Saito.The subtle role of surfaces in ion stickiness

Research shows most bird feed contains troublesome weed seeds


Research shows most bird feed contains troublesome weed seeds
Many pigweed species (Amaranthus spp.) have been found as contaminants in commercially available bird feed mixes. Pigweeds were found at an average of 384 seeds kg-1 but reached levels as high as 6,525 seeds kg-1. This photo shows a variety of pigweed species that germinated following extraction from commercial bird feed mixes. Photo credit: Mindy Ward of Penton Media Credit: Mindy Ward of Penton MediaMany millions of homeowners use feeders to attract birds. But a two-year study featured in the journal Invasive Plant Science and Management suggests there may be one unintended consequence to this popular hobby. Bird feed mixtures may be helping to spread troublesome weeds that threaten agricultural crops.
When researchers examined the contents of 98 commercially available bird feed mixes, they uncovered several significant findings:
  • The mixes contained seeds from 29 .
  • 96 percent of the mixes contained seeds for pigweed species weeds, which can represent a significant threat to agriculture.
  • One in 10 contained Palmer amaranth or waterhemp seeds that demonstrated resistance to glyphosate in a greenhouse screening.
  • Seeds from kochia, common ragweed, foxtail species and wild buckwheat were also found in many of the mixes.
The researchers also explored which harvested bird feed ingredients contributed most to  seed contamination. They found that proso millet grain was closely linked to the presence of pigweed species weeds, while safflower and sunflower contributed most to the presence of kochia and common ragweed, respectively.
"While it is difficult to estimate the precise role commercial bird feed plays, there is a distinct possibility it may be an overlooked pathway for spreading troublesome weed species into new regions," says Eric Oseland of the University of Missouri.
To mitigate the risks, researchers recommend careful weed management in  designated for bird feed, as well as the use of sieving during packaging to reduce weed seed contamination. They also point to the proven effectiveness of regulatory measures adopted in Europe to limit weed seed content in bird feed.

From Australia's Bondi Beach to the streets of New Delhi, authorities across Asia have ramped up efforts to stem the spread of the deadly novel coronavirus amid fears of a second wave of infections in places where outbreaks had appeared under control.
Tighter travel restrictions were imposed in several countries as the number of cases in the region soared past 95,000—a third of the world's infections, an AFP tally shows.
Outside China—where the virus was first detected in December and infected more than 80,000 people—South Korea is the hardest-hit country in Asia with more than 8,500 cases.
While the number of infections in China has been falling for weeks, other countries are seeing the toll gather pace from spread of the highly contagious virus.
Cases rose by roughly a third in Thailand overnight to nearly 600, fueling scepticism about claims in neighbouring Myanmar and Laos of zero infections.
Three doctors treating virus patients in Indonesia died, taking the country's death toll to 48 with 514 confirmed infections.
Most cases are in Jakarta, where businesses have been ordered closed for two weeks.
After shutting its borders to foreigners and non-residents, Australia told citizens to also cancel domestic travel plans, with the number of cases topping 1,300.
Bondi Beach and several other popular swimming spots were closed after crowds of sunbathers defied a ban on large outdoor gatherings.
Pubs, casinos, cinemas and places of worship will be shuttered for up to six months starting Monday.
India curfew
Pakistan suspended international flights in a bid to prevent the virus spreading.
Officials in Sindh—the country's second-most populous province—ordered a lockdown effective midnight.
Pakistan has reported 5,650 suspected cases, 646 confirmed infections, and three deaths from the virus.
In nearby Bangladesh, however, only 27 cases have been reported, with two deaths.
Millions of people in India were in lockdown Sunday as the government tested the country's ability to fight the pandemic.
Officials said every private sector worker in New Delhi must work from home this week unless they are providing an essential service. Most public transport will also be halted.
Billionaire Anand Mahindra, whose vast Mahindra Group business empire includes cars and real estate, said his manufacturing facilities would try to repurpose to make ventilators.
Testing has expanded in the country of 1.3 billion people amid concerns that the 360 reported cases, including seven deaths, vastly understates the true scale of the crisis.
People took to their balconies in major cities after Prime Minister Narendra Modi urged Indians to thank medical workers and emergency personnel by clapping or banging pots and pans for five minutes at 5:00 pm Sunday.
The World Health Organization has called for "aggressive" action in Southeast Asia, fearing that a major outbreak could cripple the region's often decrepit health care systems.
Second wave
Authorities are now dealing with a second wave of infections in places where outbreaks appeared to have been brought under control as people return from abroad.
Singapore is banning all short-term visitors to the densely populated city-state after a surge of imported cases took its total to 445—including its first two deaths on Saturday.
In Hong Kong, where the worst had appeared to be over, the number of cases nearly doubled in the past week as more people fly back to the financial hub.
Infections in Malaysia hit 1,306—more than half linked to an international Islamic gathering held last month, with attendees later returning to Singapore and Indonesia with the virus.
In Sri Lanka, where 82 cases were reported, guards fired on inmates in a northern prison when they tried to break out, angry over a ban on family visits to prevent the spread of the virus.
Two convicts were killed and six others wounded.
Authorities also put restrictions on the sale of two malaria treatments amid fears of a run on the drugs after US President Donald Trump said that they might be effective to prevent a COVID-19 virus infection—though scientists agree that only more trials would determine if chloroquine really works and is safe.
Papua New Guinea, which has one confirmed infection, declared a 30-day state of emergency and halted domestic flights and public transport for two weeks.
Guam, which has 15 cases, confirmed a 68-year-old woman had died of COVID-19—the first virus-related death in the Pacific.

Crisis-hit Venezuelans turn to homemade remedies to fight virus

Faced with the coronavirus pandemic on top of an economic crisis that has left shortages of medicines and medical supplies, Venezuelans are turning to homemade remedies to protect themselves.
Whether it's hot drinks infused with lemon, salt, garlic or onions, cash-strapped Venezuelans are cooking up concoctions handed down from one generation to another.
No sooner had Venezuela announced its first  cases than Dilia Zorrilla ran to the shops to buy , anti-bacterial gel, alcohol and chlorine, but also onions for the hostel she runs in Guiria, a remote village in the northwest, 600 kilometers (370 miles) east of the capital Caracas.
She asked her employees to place the onions in a glass bowl at the feet of a statue of the Virgin Mary, who is particularly venerated on the Caribbean coast.
"And that is not too many," she said. Local legend has it that onions can ward off illnesses.
When new guests arrive at the hostel, which smells of onions, Zorrilla puts a drop of antiseptic gel in their hands and advises them to go out and buy gloves and face masks.
She also serves them a citric herbal tea. "You must drink it," she orders.
In this remote area, Zorrilla feels cut off from information. Television and telephone signals are unreliable.
"Here, everything we know has come from social media," the 42-year-old told AFP.
'Part of the desperation'
In this region infested with drug-traffickers and , these elixirs form part of the secrets handed down from one generation to the next.
For surgeon Jaime Lorenzo from the United Doctors NGO "these measures are part of the desperation" caused by a pandemic that has already killed 13,000 people worldwide, but which has affected just 42 people so far in Venezuela.
"As scientists, all remedies need to be based on scientific evidence," Lorenzo told AFP.
While these concoctions may have been passed down through generations, none of them has been scientifically tested, Lorenzo said.
The best advice, as espoused by President Nicolas Maduro, is to stay at home.
Since the beginning of the week, Venezuela has been under a near-total lockdown.
People are only allowed out to buy food or medicines. Schools are closed and most air transport links suspended.
Police and soldiers patrol the roads to ensure the decree is respected.
But long before COVID-19 arrived in Venezuela, the health system had already collapsed and it was often hard to get hold of medicines, either due to their exorbitant cost or scarcity in pharmacies.
'We're not prepared'
People have turned to homemade remedies even to treat cancer.
So "we're just not prepared" to face a pandemic, said 53-year-old trader Alodia Anton, who turned up at the Guiria hospital to have her blood pressure taken.
But it wasn't possible "because they don't have a  meter on the emergency ward."
Her biggest fear is that she or someone close to her would need emergency medical care: the main hospital in the region is in Cumana, a six-hour drive away on poorly surfaced roads.
So Anton makes do with "advice" her sister sends her by WhatsApp from the United States, such as "drink hot tea" with lemon, camomile or "whatever," wash the floor with vinegar and keep onions in her room.
Lorenzo warns against believing "myths" that hot drinks can weaken COVID-19, but that message isn't getting through.
"We're drinking boiled water with garlic and lemon," says a tearful Rosa Solangel through a face mask.
The 56-year-old cook fears for the health of her three children who have left the country for Brazil, Peru and Colombia—4.9 million people have fled Venezuela's economic meltdown since the end of 2015 according to UN data.

Welcome to the first social media pandemic. 

Here are 8 ways you can stop the spread of 

coronavirus misinformation.

Credit: CC0 Public Domain
The alarming messages ping our laptops and phones and parachute into our social media feeds, text messages and private chat groups.
Be prepared for a national quarantine. Martial law is coming.
The coronavirus was cooked up in a bioweapons lab by the CIA, or the pharmaceutical industry, or was funded by the the Bill & Melinda Gates Foundation to boost vaccine sales.
Sip water every 15 minutes, gargle with ethanol or eat raw garlic to ward off infection.
None of it is true, but, as public fear and uncertainty grow with the rise in deaths and confirmed cases across the U.S., we are becoming increasingly susceptible to these wildly false and sometimes hazardous claims that tap into our urgent need for the latest information about how to protect ourselves and our families.
Too often we pass along the misinformation we pick up, unwittingly exposing our loved ones to a flood of conspiracy theories, hoaxes and falsehoods that could mislead or even harm them.
So much misinformation is being transmitted from person to person that the scale is unprecedented, public health experts say. Unlike localized disasters such as hurricanes or mass shootings, the coronavirus outbreak is dominating the public conversation on every single social media platform.
COVID-19 is the world's first social media pandemic
"This is our first social media pandemic," says Carl Bergstrom, a professor of biology at the University of Washington who researches disinformation. "This is the first time we've had a pandemic where the population is relying heavily on social media for information."
Shelter-in-place orders and other restrictions on our daily lives have only exacerbated the  warn.
Hunkered down in their homes and isolated from their jobs and communities, people are connecting with friends and family on social media as they search for answers in a rapidly-evolving global public health crisis.
What they encounter instead: profiteers hawking "cures," cyber thieves trying to steal their , ideologues who distrust science or troublemakers intent on sowing confusion and distrust.
"There's a high degree of uncertainty and obviously a lot of fear and that creates a kind of perfect storm," says Peter Adams, senior vice president of education at the News Literacy Project. "Really well-intentioned people are trying to make sense of this and help friends and family to the greatest degree possible so they just sort of share everything they see and that turns into this over abundance of information, a lot of which isn't true."
The World Health Organization was so alarmed that, in February, it warned of a massive "infodemic," shorthand for information epidemic, "an overabundance of information—some accurate and some not—that makes it hard for people to find trustworthy sources and reliable guidance when they need it."
The 'life-and-death consequences' of misinformation during coronavirus
"This is a moment where misinformation can have real consequences, beyond what we have seen in elections," says Dhavan Shah, the Louis A. & Mary E. Maier-Bascom professor at the University of Wisconsin-Madison, director of the university's Mass Communication Research Center and scientific director of the Center for Health Enhancement System Studies. "This is a moment where misinformation can have life-and-death consequences."
Kathleen M. Carley, who directs Carnegie Mellon's Center for Computation Analysis of Social and Organizational Systems, has been researching the spread of coronavirus misinformation since January. She has identified three types of misinformation so far:
  • Fake cures or preventative measures such as taking colloidal silver, steroids, acetic acid, essential oils and cocaine; gargling with salt water; spraying chlorine on your body and avoiding ice cream.
  • False information about the nature of the virus such as COVID-19 is just a cold or a normal flu and children cannot catch it.
  • Conspiracy theories such as COVID-19 was bioengineered by a Russian bioweapons lab or was caused when an infected rat bit a student in a bioweapons lab in China.
Carley expects new sorts of misinformation to emerge around topics like coronavirus testing " to incite panic and sow confusion."
Who's fighting back against coronavirus misinformation?
Groups like Carley's are analyzing the waves of misinformation and informing the public. Fact-checking groups are debunking fake coronavirus cures, false news reports and conspiracy theories.
The WHO is working with Facebook, Twitter and other platforms to crack down on coronavirus misinformation. Influencers on Facebook-owned Instagram and Google-owned YouTube are being drafted to spread accurate news about the virus.
On Monday, Facebook joined seven other platforms—Google, Microsoft, Twitter, Reddit, YouTube and Microsoft's LinkedIn—in pledging to crack down on coronavirus misinformation as a direct threat to public welfare. And CEO Mark Zuckerberg told reporters Wednesday that Facebook is launching an information hub that will appear at the top of everyone's news feeds to counteract misinformation with facts about COVID-19.
Also on Wednesday, Facebook-owned WhatsApp announced it would give $1 million to support the International Fact-Checking Network in its fight against COVID-19 misinformation.
"The top priority and focus for us has been making sure people can get access to good authoritative information from trusted health sources," Zuckerberg said.
So, how can you practice better information hygiene? Here are some tips:
Arm yourself with the facts
We are all susceptible to misinformation. As the saying goes, "A lie can travel halfway around the world while the truth is still putting on its shoes." The peddlers pushing false or misleading content prey on our biases and our behavior, especially in a crisis.
"As people turn from traditional media sources, governmental agencies, NGOs to whatever is flying around this hour on social media, we feel like we are getting better and better information because it's more recent, but we are actually getting much worse information because it hasn't been adequately vetted," Bergstrom says. "The hunger for knowing what's happening up to the minute is driving people into the arms of people who are spreading rumors and disinformation on the internet."
Turn instead to public health officials such as The Centers for Disease Control and Prevention and the World Health Organization for information on the virus. What are the symptoms? How does it spread? The more information you know, the easier it will be to identify misinformation.
Treat anything not clearly attributed and linked back to one of those organizations with suspicion. "Above all else, what we are really urging people to do is consider the source," Adams says.
Take 20 seconds to research before sharing
Just like washing your hands for 20 seconds, take 20 seconds to research each piece of information you come across before passing it on.
"You can do a lot in 20 seconds when you encounter something in a social media feed," Adams says. "Check the comments to see if anyone has posted a link to a fact check of the claim or open a new tab and do a quick Google search for the claim 'does garlic help prevent coronavirus' and you will quickly turn up fact checks from credible fact-checking organizations."
Do not spread misinformation about prevention or cures
Bogus tips on how to prevent or cure coronavirus are blazing across social media. Some tips are harmless, like eating raw garlic to prevent infection. Others are dangerous and potentially life-threatening. You can debunk these tips by checking with the CDC or WHO. Don't share posts that could physically harm others.
Beware posts that traffic in fear
Research social media posts and messages that deliberately incite fear, strain credulity or are just too reassuring or comforting to be true. Ask yourself: Why is someone trying to make me feel this way?
Don't trust everything you see
We instinctively trust images and video, but they can be taken out of context, edited or digitally manipulated to mislead us. So check with trusted sources of information such as health experts. Or do a Google search or a Google image search to research if images and videos have been manipulated.
Don't join the crowd
Misinformation needs a crowd, the bigger the better. Sure, Kremlin-linked operatives produce shady content. Bots pepper social media with automated posts. But effective  campaigns thrive by recruiting unsuspecting members of the public who don't realize they are amplifying and legitimizing falsehoods or posts seeking to inflame tensions or disrupt American life. Cross check information with the CDC or WHO before sharing it with others.
Keep partisan politics out of it
We live in a deeply partisan world with bitter divisions between the political right and left, especially in the run-up to the 2020 presidential election. Be wary of efforts to downplay or exaggerate the threat of the coronavirus to attack one side or the other.
Uncertainty sucks, get used to it
Scientists are learning more each day about the virus and its spread, but it may take weeks, possibly months, for them to responsibly answer all of our questions. Don't fill the vacuum with unreliable information, Bergstrom advises.
"My hope is as this progresses, people will realize, 'Boy, I get burned every time I follow some credible-seeming anonymous thread on the internet, but when I read an article in U.S. TODAY, I haven't been burned yet," he said. "I hope that people would eventually start to figure that out.

One tough power source: Creating a lithium-ion battery that cannot catch fire


Credit: TOBATRON
The popular myth that a spider is never more than a few feet away is arguably more true of lithium-ion batteries than of arachnids. Powering everything from smartphones and laptops to electronic cigarettes, lithium-ion batteries beat out alternative sources of power because of their top-notch energy density and long life cycle, meaning they can be recharged over and over again before breaking down. Yet for all these advantages, lithium-ion batteries come with a major concern: They can catastrophically ignite when they overheat.
At the Johns Hopkins Applied Physics Laboratory, a new type of   that cannot catch fire is in the works. A team of researchers led by Konstantinos Gerasopoulos, a senior research scientist at the lab, recently made breakthroughs in their development efforts. The new battery is thin and flexible, unlike today's  that must be packaged in rigid cylindrical or polygonal cases to wall off their volatile contents. The APL battery is also tough, able to withstand submersion in water, cutting, and even ballistic impacts.
"We wanted to create a battery that is as thin and powerful as the electronics it's intended to power," Gerasopoulos says. "And to do that, we needed to transform the battery's safety."
Swap out for safety
In batteries, a  conveys electrons between two electrodes, providing an  that powers your device. Standard lithium-ion batteries contain an electrolyte with an organic solvent that, while efficient, happens to be flammable. Gerasopoulos and colleagues have developed a new class of electrolyte that uses lithium salts dissolved in water as an inflammable solvent. A —basically, a kind of plastic sponge—soaks up the water, and the ultimate result is a bendable, soft, contact lens-like electrolyte.
The positive with the negative
Usually, lithium-ion battery electrodes are foil-like and, when bent too much, can crinkle and be damaged. APL's battery electrodes are instead crafted with Kapton, a flexible film often used to insulate a spacecraft from extreme temperatures. As an added bonus, Kapton is a readily available, off-the-shelf material, reducing the battery's cost and complexity to manufacture.
More power for longer
The current iteration of the new electrolyte sustains 4.1 volts—not quite as much as conventional lithium-ion batteries, but it's inching closer. The APL team also wants to improve the battery's life cycle from around a hundred charges to more like a thousand, matching today's typical battery performances. Continued tweaking of the polymer's chemistry for better electrochemical stability should deliver on these two objectives.

Robopets: Using technology to monitor older adults raises privacy concerns

Robotic pets could increasingly provide social companionship and health

Social isolation and loneliness are concerns for many older adults, and can be triggered by the need to transition to a condo, rental accommodation, long-term care facility or retirement home.
Sometimes, the only thing standing between an older adult and loneliness may be a beloved pet. This reciprocal relationship of affection and attention between human and non-human animal translates into physical and mental health benefits. However, in many cases, pets can't move with their  since very few jurisdictions guarantee the right to bring an animal into a rental unit or condominium.
My research asks: what are the factors that impact well-being in older age? I explore the impacts of technology on privacy, autonomy and well-being, as well as the effects of the human-animal bond on health and well-being. I am also interested in whether social robots, including robopets, can produce the same effects.
In-home surveillance
Whether moving to a long-term care facility or a smaller home, many older adults find themselves subjected to increasing surveillance. Well-meaning family and caregivers install cameras, sensors and other devices to monitor independent older adults.
Social robots are new tools in the care of older adults. Some provide health-related services such as medication reminders, but most try to make up for the absence of human and animal companionship. These robots have artificial intelligence (AI) that is designed to interact with and provide comfort to the user.
For example, ElliQ is a small table-mounted device that interacts with a screen to enable "family members to easily check in." It also interacts with the user, suggesting activities, responding to their voice or touch or look. ElliQ is always on, collecting data on the user that is transmitted to the manufacturer.
Jennie is a  dog controlled by voice commands and through a smartphone app. Robot pets, like other social robots, are designed to respond to the user's emotions and, to do so, it engages in constant surveillance.
The responsiveness of  and robot pets relies on sensors to detect , record emotions and forward this information to be analyzed by algorithms that inform the robot's response. The results of the data analysis prompt the robot to smile or purr or snuggle. In the case where a health response is required, some robots can inform the caregiver of elevated blood pressure.
Robopets: Using technology to monitor older adults raises privacy concerns

Collecting personal data
Every step of this data process involves personal and sensitive information about an individual. For example, user identification data might be leaked at the sensing layer or in the cloud where the data is analyzed to determine the right response. User profiles contain not only identifying information such as name and address, but also data gathered on user moods, behaviors and habits.
Older adults are not always aware of the extent of the monitoring, which can lead to feelings of shame and humiliation if, for example, a person is caught on camera singing, dancing, engaging in sexual acts or crying. It is not that older adults don't realize that there is monitoring equipment, it is the 24/7 always-on aspect that may be unfamiliar to them. While enabling older adults to live with less human or animal contact, these monitoring systems and robots can increase their exposure and vulnerability.
Peer networks
The increasing number of surveillance-based options for providing care and companionship to older adults also ignores the reality that there are often other older adults who want to contribute meaningfully to their community. Using technology to build opportunities for human-to-human or human-to-animal interactions is one way to increase well-being without sacrificing privacy. For example, during virus season, technology could be used to develop something as simple as a telephone tree so that people can check in and connect in times of social distancing.
Other internet-based programs have been developed to support older adults to "age in place" with their companion animals. For example, Pet Assist, in Calgary, Alta., will help older adults manage pet-related tasks at home.
After all, patting a robot dog is not the same as cuddling with a beloved pet. And a real dog will never tell anyone that you danced around the house in your underwear.
Aging with pets isn't just a sentimental concern, but a matter of health and wellness

Zero emissions: government must address hurdles putting people off electric cars

Ambitious targets have been set by the UK and Scottish governments to become net-zero carbon economies by 2050 and 2045 respectively. But a variety of initiatives will be required on the part of government, industry and society to achieve this target.
Every industry will be required to have carbon reduction at the centre of what it does and rapidly introduce new technologies to achieve zero emissions from their activities. The question is how this should be done.
Take the case of cars, which are a major contributor of carbon emissions. According to one estimate, transport contributes to 30% of the EU's total emissions, with road transport contributing 72%. With this figure expected to rise, any strategy to reduce overall emissions should tackle this element aggressively.
The UK government has announced its intention to ban petrol, diesel and  by 2035. With a third of the UK's carbon emissions coming from road transport, the government's combative posturing is understandable. But is banning combustion fuel technology the most appropriate way to reduce emissions from road transport?
This is how we do it
There are two issues to consider: one, readiness of alternative technologies to replace petrol and diesel on a mass scale; and two, in a democratic society, bans should be used as only a measure of last resort.
There is overwhelming scientific evidence that smoking causes serious harm to a person's health to the extent it could kill them. But cigarette production is not banned. To control consumption of cigarettes, governments have introduced a wide range of legislation that limits their sale rather than banning their manufacture.
So rather than banning the production of petrol and diesel cars, governments should rapidly introduce effective policies that would make the cleaner technologies more attractive to users. Research on long-term technological change shows once a technology is entrenched in an industry, it leads to "path-dependency, which means that because shifting to alternative technologies can be costly—both for manufacturers and customers—industries often remain locked into existing technology.
Insights from our research into the century-long decline of Dundee's jute textile industry suggests that for any new technology to break dependency on existing dominant technology it must address two conditions: price (compared to the existing cost) and technical performance.
Looking back
The car industry has its roots in electric technology. The rechargeable battery was the dominant technology from the mid to late 19th century. But the discovery of new petroleum reserves and the invention of the combustion fuel engine in the early 20th century gave the petrol car a price and performance advantage over electric technology. This led to widespread adoption, making the combustion fuel engine dominant for over a century, leaving the car industry path-dependent on this technology.
But the industry has invested in innovation to break this dependency with alternative technologies, and hydrogen and electric have been around for quite some time. The electric car made a comeback in 1970s in response to the oil crisis. But with the fall in prices later that decade, the electric car was no longer an attractive proposition. In 1996 General Motors introduced its EV1 in response to the 1990 legislaton by the state of California which required 2% of their sales to be zero emissions.
Toyota also introduced its hybrid Prius in 1997 followed by Audi and Honda models. However, all the early electric cars had less than a 100-mile range and were relatively expensive. The cost and limited range issues have continued to hinder the widespread uptake of alternative technologies and the industry has remained locked into the combustion fuel engine in the two decades since.
Getting in gear
These days we are beginning to see performance issues addressed in electric cars. Many are now able to cover anywhere from 150 to 230 miles without recharging. Of course this is still far from what a diesel would offer on a full tank, but customers are gaining confidence.
Car manufacturers—existing makes and new players like Tesla—possess the technology to improve the performance of electric cars, and this will continue to advance. It is in their commercial interest to develop swiftly, to give them a competitive edge. But the main hurdle is price; electric cars are still more expensive than petrol and diesel cars—something industry bodies have emphasised.
Banning the production of petrols and diesels will not make electric cars cheaper. If the price of electric cars remains higher, it will only trap customers into a costly commitment. An MIT study has found that a mid-sized electric car is likely to be around £4,300 more expensive to the manufacturer than combustion fuel through to 2030. If the UK government is serious about facilitating this technology shift, it must provide serious long-term policies to help reduce the cost of electric cars.
There are two ways to make the price of electric technology more competitive. First, make owning petrol and  expensive by imposing a "gasoline car tax." This is currently practised in a mild version in the form of a congestion charge in many cities, and a higher car tax on diesel engines. But it has not helped to achieve the ambitious electric goal.
Imposing further tax such as additional fuel duty could make driving petrol and diesel vehicles more expensive—but without viable cheaper alternatives, it will not go down well with the electorate and could add to economic woes. The second, and recommended option, that emerges from our research is to introduce incentives that make purchasing and running an electric car cost effective.
Today, many people have a genuine desire to buy an electric car. This market will only increase—customers are already sold on the benefits. But the price tag holds most back from making that final purchase decision. The trajectory of electric technology is at a critical juncture where a properly competitive price will convince buyers to make it their next purchase. And if the government gets it right, this model can be applied to other industries where there is a pressing need to shift to lower-carbon technologies.
