Researchers from the University of Houston, in collaboration with others, have designed a "catch and kill" air filter that can trap the virus responsible for COVID-19, killing it instantly.

Zhifeng Ren, director of the Texas Center for Superconductivity at UH, collaborated with Monzer Hourani, CEO of Medistar, a Houston-based medical real estate development firm, and other researchers to design the filter, which is described in a paper published in Materials Today Physics.

The researchers reported that virus tests at the Galveston National Laboratory found 99.8% of the novel SARS-CoV-2, the virus that causes COVID-19, was killed in a single pass through a filter made from commercially available nickel foam heated to 200 degrees Centigrade, or about 392 degrees Fahrenheit. It also killed 99.9% of the anthrax spores in testing at the national lab, which is run by the University of Texas Medical Branch.

"This filter could be useful in airports and in airplanes, in office buildings, schools and cruise ships to stop the spread of COVID-19," said Ren, MD Anderson Chair Professor of Physics at UH and co-corresponding author for the paper. "Its ability to help control the spread of the virus could be very useful for society." Medistar executives are is also proposing a desk-top model, capable of purifying the air in an office worker's immediate surroundings, he said.

Ren said the Texas Center for Superconductivity at the University of Houston (TcSUH) was approached by Medistar on March 31, as the pandemic was spreading throughout the United States, for help in developing the concept of a virus-trapping air filter.

Luo Yu of the UH Department of Physics and TcSUH along with Dr. Garrett K. Peel of Medistar and Dr. Faisal Cheema at the UH College of Medicine are co-first authors on the paper.

The researchers knew the virus can remain in the air for about three hours, meaning a filter that could remove it quickly was a viable plan. With businesses reopening, controlling the spread in air conditioned spaces was urgent.

And Medistar knew the virus can't survive temperatures above 70 degrees Centigrade, about 158 degrees Fahrenheit, so the researchers decided to use a heated filter. By making the filter temperature far hotter - about 200 C - they were able to kill the virus almost instantly.

Ren suggested using nickel foam, saying it met several key requirements: It is porous, allowing the flow of air, and electrically conductive, which allowed it to be heated. It is also flexible.

But nickel foam has low resistivity, making it difficult to raise the temperature high enough to quickly kill the virus. The researchers solved that problem by folding the foam, connecting multiple compartments with electrical wires to increase the resistance high enough to raise the temperature as high as 250 degrees C.

By making the filter electrically heated, rather than heating it from an external source, the researchers said they minimized the amount of heat that escaped from the filter, allowing air conditioning to function with minimal strain.

A prototype was built by a local workshop and first tested at Ren's lab for the relationship between voltage/current and temperature; it then went to the Galveston lab to be tested for its ability to kill the virus. Ren said it satisfies the requirements for conventional heating, ventilation and air conditioning (HVAC) systems.

"This novel biodefense indoor air protection technology offers the first-in-line prevention against environmentally mediated transmission of airborne SARS-CoV-2 and will be on the forefront of technologies available to combat the current pandemic and any future airborne biothreats in indoor environments," Cheema said.

Hourani and Peel have called for a phased roll-out of the device, "beginning with high-priority venues, where essential workers are at elevated risk of exposure (particularly schools, hospitals and health care facilities, as well as public transit environs such as airplanes)."

That will both improve safety for frontline workers in essential industries and allow nonessential workers to return to public work spaces, they said.

Consumers prefer round numbers even when the specific number is better news

Surprising findings have implications for public health and economic marketing

RENSSELAER POLYTECHNIC INSTITUTE

 

TROY, N.Y. -- Consider this scenario: A vaccine for the novel coronavirus has been developed that is 91.27% effective. If public health officials present this information using the specific number, people are likely to think the vaccine is actually less effective than if it is presented as being 90% effective.

This concept is a real-life application of recent findings from Gaurav Jain, an assistant professor of marketing in the Lally School of Management at Rensselaer Polytechnic Institute, published recently in Organizational Behavior and Human Decision Process.

The paper, titled "Revisiting Attribute Framing: The Impact of Number Roundedness on Framing," explores an area of behavioral economics research pertaining to attribute framing, which evaluates how people make decisions based on the manner in which information is presented.

Watch this video to learn more.

For decades, researchers in this field have been focused on the attributes, the adjectives, and other words that describe what is being measured. In this paper, Jain looked at the numbers that are used in the frames themselves.

Using six sets of data with more than 1,500 participants, Jain and his co-authors considered what would happen to peoples' perception of information when specific, or non-round, numbers were used instead of round numbers.

The research showed that people find non-round numbers unique and jarring. Jain and his team determined that people pause to think about the specific number due to its uniqueness. Because it isn't easy to comprehend, people tend to compare the non-round number to an easily understood ideal standard -- like 100%. Then, because the specific number doesn't live up to the ideal, people perceive it negatively.

"Numbers have a language and give non-numerical perceptions," Jain said. "When we use specific numbers, the evaluations decrease. There was no apparent reason for this kind of behavior, and this was incredibly surprising."

While Jain and his team explored this question using standard behavioral economic research scenarios and not a specific question, such as communications regarding a potential coronavirus vaccine, this research has direct and critical impact in marketing and public health messaging.

"The extensive use of attribute framing in marketing, organizational behavior, and public policy communication and the robustness of the effects in experimental settings make it one of the most important and frequently studied phenomena in the field," Jain said. "Managers and public health officials should be careful when using non-round numbers, because the use of this approach in communication messages may decrease the subjective evaluations of the target on the associated attributes."

According to Jain, the paper also helps to add to the theoretical understanding of attribute framing. "Our studies lend support and offer an elaborated process account for the attention-association-based reasoning for framing effects in general, which adds to the scarce literature on processes underlying framing effects," Jain said.

Making a list of all creatures, great and small

A paper published July 7, 2020 in the open access journal PLOS Biology outlines a roadmap for creating, for the first time, an agreed list of all the world's species, from mammals and birds to plants, fungi and microbes.

"Listing all species may sound routine, but is a difficult and complex task," says Prof. Stephen Garnett of Charles Darwin University, the paper's lead author. "Currently no single, agreed list of species is available." Instead, some iconic groups of organisms such as mammals and birds have several competing lists, while other less well-known groups have none.

This causes problems for organizations and governments that need reliable, agreed, scientifically defensible and accurate lists for the purposes of conservation, international treaties, biosecurity, and regulation of trade in endangered species. The lack of an agreed list of all species also hampers researchers studying Earth's biodiversity.

The new paper outlines a potential solution - a set of ten principles for creating and governing lists of the world's species, and a proposed governance mechanism for ensuring that the lists are well-managed and broadly acceptable.

"Importantly, it clearly defines the roles of taxonomists - the scientists who discover, name and classify species - and stakeholders such as conservationists and government and international agencies," says Dr Kevin Thiele, Director of Taxonomy Australia and a co-author on the paper. "While taxonomists would have the final say on how to recognize and name species, the process ensures that stakeholders' needs are considered when deciding between differing taxonomic opinions."

The Earth's species are facing unprecedented threats, from global heating, pollution, land clearing, disease and overutilization, which together are driving an unprecedented and accelerating extinction crisis. "Developing a single, agreed list of species won't halt extinction," says Garnett, "but it's an important step in managing and conserving all the world's species, great and small, for this and future generations."

More ecosystem engineers create stability, preventing extinctions

SANTA FE INSTITUTE

 NEWS RELEASE 3-JUL-2020

When we think of engineering in nature, we tend to think of beavers -- the tree-felling, dam-building rodents whose machinations can shape the landscape by creating lakes and changing the path of rivers. But beavers are far from the only organisms to reshape their environment. A squirrel who inadvertently plants oak trees is also an "ecosystem engineer" -- roughly speaking, any organism whose impact on the environment outlasts its own lifetime. The coolest of these biological builders, according to Justin Yeakel, might be the shipworm, which eats through rocks in streams, creating cozy abodes for future invertebrate inhabitants.

Yeakel, an ecologist at the University of California, Merced, and a former Santa Fe Institute Omidyar Fellow is the lead author of a new paper that models the long term impact of ecosystem engineers. Researchers have long considered the role of ecosystem engineers in natural histories, but this study is among the first to quantitatively assess them in an ecological network model.

"We wanted to understand how food webs and interaction networks were established from a mechanistic perspective," he says. "To do that, you have to include things like engineering because species influence their environment and there's this feedback between the environment to the species."

In particular, the model uses simple rules to show how food webs can be assembled, how species interactions can change over time, and when species go extinct. One striking result: Few ecosystem engineers led to many extinctions and instability while many ecosystem engineers led to stability and few extinctions.

"As you increase the number of engineers, that also increases the redundancy of the engineers and this tends to stabilize the system," Yeakel says.

So, how do you create an ecological network model? It's highly abstracted -- there are no specific species like beavers or concrete environmental features like rivers. Everything is reduced to interactions: species can eat, need, or make. In this sense, nature becomes a network of interactions. For example, bees eat nectar from flowers; flowers need bees to be pollinated; trees make shade which flowers need.

The researchers gave the model a small number of rules, the main one being: Species have to eat only one thing to survive but they have to obtain all of the things they need. In less abstract terms, even if one flower species goes extinct, bees could survive on nectar from other flowers. But if either bees or trees fail to provide pollination or shade, which flowers need, then the flowers will go extinct.

Using these rules, the models were able to produce ecological networks similar to those in the real world, with a characteristic hourglass shape in species diversity -- more diversity at the top and the bottom of the web, less in the middle. To expand the model for future research, Yeakel plans on incorporating evolutionary dynamics so that species can change what they eat and need and make.

Two and a half billion years before humans showed up, cyanobacteria were a planetary-scale engineer that slowly changed the composition of the entire atmosphere by oxygenating it. But unlike our photosynthetic predecessors, "we're making changes on ecological timescales rather than evolutionary timescales," Yeakel says. "Is an organism that becomes a planetary-scale engineer doomed to extinction if it changes the environment too quickly?"

Study: Troubling connection between workplace pregnancy discrimination and health of mothers, babies

Researcher shares practical steps for managers to combat discrimination

WACO, Texas (July 7, 2020) - Perceived pregnancy discrimination indirectly relates to increased levels of postpartum depressive symptoms for mothers and lower birth weights, lower gestational ages and increased numbers of doctor visits for babies, according to a management study led by Baylor University.

The study - "Examining the Effects of Perceived Pregnancy Discrimination on Mother and Baby Health" - is published in the Journal of Applied Psychology.

"Despite being illegal, pregnancy discrimination still takes place in the workplace," said lead author Kaylee Hackney, Ph.D., assistant professor of management in Baylor University's Hankamer School of Business. "Obviously, this is troublesome. Our research highlights the negative impact that perceived pregnancy discrimination can have on both the mother's and the baby's health."

The researchers surveyed 252 pregnant employees over the course of two studies. They measured perceived pregnancy discrimination, perceived stress, demographics and postpartum depressive symptoms. The second study included the measurements of the babies' health outcomes, including gestational age (number of weeks of pregnancy when the baby was delivered), Apgar score (heart rate, respiration, muscle tone, reflex response and color), birth weight and visits to the doctor.

Sample survey statements and questions used to measure perceived discrimination, perceived stress and postpartum depressive symptoms included: "Prejudice toward pregnant workers exists where I work," "In the last month, how often have you felt nervous or stressed?" and "I am so unhappy that I cry." Mothers also logged their babies' health outcomes.

"I think the biggest surprise from this research is that pregnancy discrimination not only negatively impacted the mother, but also negatively impacted the baby she was carrying while experiencing the discrimination," Hackney said. "This just shows the far-reaching implications of workplace discrimination and highlights the importance of addressing it."

More than 50,000 discrimination claims in a decade

The study noted that over the last decade, more than 50,000 pregnancy discrimination claims were filed with the Equal Employment Opportunity Commission and Fair Employment Practices Agencies in the United States.

Pregnancy discrimination is defined as unfavorable treatment of women at work due to pregnancy, childbirth or medical conditions related to pregnancy or childbirth, Hackney said. Pregnant women perceive discrimination when they experience subtly hostile behaviors such as social isolation, negative stereotyping and negative or rude interpersonal treatment.

Examples might include lower performance expectations, transferring the pregnant employee to less-desirable shifts or assignments or inappropriate jokes and intrusive comments.

Practical steps for managers

Given that pregnancy discrimination led to adverse health outcomes through increased stress, the researchers believe managers are in a unique position to provide the support that pregnant employees need to reduce stress.

Some steps managers might take include:

• Providing flexible schedules
• Keeping information channels open and the employee in the loop, specifically with regards to work-family benefits and expectations leading up to leave/returning from leave
• Accommodating prenatal appointments
• Helping to plan maternity leave arrangements
• Normalizing breastfeeding in the workplace

"Overall, I would suggest that managers 1) strive to create a workplace culture where discrimination does not take place and 2) not make assumptions about what pregnant employees want," Hackney said. "The best approach would be to have an open dialogue with their employees about what types of support are needed and desired."

Healthcare partnerships

In addition, Hackney said the findings suggest that healthcare organizations may find opportunities to provide guidance and outreach to workplaces to help pregnant workers reduce stress via reduced pregnancy discrimination and enhanced work-family support for pregnant women.

Some steps may include training managers to be more family supportive and less biased against expectant mothers, she said.

Positive thinking has long been extolled as the route to happiness, but it might be time to ditch the self-help books after a new study shows that realists enjoy a greater sense of long-term wellbeing than optimists.

Researchers from the University of Bath and London School of Economics and Political Science (LSE) studied people's financial expectations in life and compared them to actual outcomes over an 18-year period. They found that when it comes to the happiness stakes, overestimating outcomes was associated with lower wellbeing than setting realistic expectations.

The findings point to the benefits of making decisions based on accurate, unbiased assessments. They bring in to question the 'power of positive thinking' which frames optimism as a self-fulfilling prophecy, whereby believing in success delivers it, along with immediate happiness generated by picturing a positive future.

Negative thinking should not replace positive thinking though. Pessimists also fared badly compared to realists, undermining the view that low expectations limit disappointment and present a route to contentment.

Their numbers are dwarfed though by the number of people - estimated to be 80 percent of the population - who can be classed as unrealistic optimists. These people tend to overestimate the likelihood that good things will happen and underestimate the possibility of bad things. High expectations set them up for large doses of destructive disappointment.

"Plans based on inaccurate beliefs make for poor decisions and are bound to deliver worse outcomes than would rational, realistic beliefs, leading to lower well-being for both optimists and pessimists. Particularly prone to this are decisions on employment, savings and any choice involving risk and uncertainty," explains Dr Chris Dawson, Associate Professor in Business Economics in Bath's School of Management.

"I think for many people, research that shows you don't have to spend your days striving to think positively might come as a relief. We see that being realistic about your future and making sound decisions based on evidence can bring a sense of well-being, without having to immerse yourself in relentless positivity."

The results could also be due to counteracting emotions, say the researchers. For optimists, disappointment may eventually overwhelm the anticipatory feelings of expecting the best, so happiness starts to fall. For pessimists, the constant dread of expecting the worst may overtake the positive emotions from doing better than expected.

In the context of the Covid-19 crisis the researchers highlight that optimists and pessimists alike make decisions based on biased expectations: not only can this lead to bad decision making but also a failure to undertake suitable precautions to potential threats.

"Optimists will see themselves as less susceptible to the risk of Covid-19 than others and are therefore less likely to take appropriate precautionary measures. Pessimists, on the other hand, may be tempted to never leave their houses or send their children to school again. Neither strategy seems like a suitable recipe for well-being. Realists take measured risks based on our scientific understanding of the disease," said co-author Professor David de Meza from LSE's Department of Management.

Published in the American journal Personality & Social Psychology Bulletin the, findings are based on analysis from the British Household Panel Survey - a major UK longitudinal survey - tracking 1,600 individuals annually over 18 years.

To investigate whether optimists, pessimists or realists have the highest long-term well-being the researchers measured self-reported life satisfaction and psychological distress. Alongside this, they measured participants' finances and their tendency to have over- or under-estimated them.

Study: Interplay of impact, moral goals influences charitable giving to different causes

UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN, NEWS BUREAU

CHAMPAIGN, Ill. -- Charitable giving is a nearly half-trillion-dollar sector of the U.S. economy, but what accounts for why some individuals, foundations and corporations give locally while others give to charities on the other side of the globe? According to a new paper co-written by a University of Illinois at Urbana-Champaign expert in consumer behavior and global marketing, the dynamic interplay between the accessibility of local impact versus more global goals can influence charitable behaviors between donors and recipients.

An appeal to morality can persuade people to make donations that benefit recipients halfway around the world - even though those same resources could be allocated to helping those with similar needs who live closer, said Carlos Torelli, a professor of business administration and the James F. Towey Faculty Fellow at Illinois.

"Although past research suggests that people are more likely to donate money to nearby causes to maximize the positive impact on their local community, donations to foreign causes are growing rapidly," he said. "With the rise of globalization, geographic borders are becoming less relevant for making charitable donations, which means nonprofits and charities can make more effective pitches to donors by emphasizing higher-level concepts such as morality and idealistic values."

Torelli and his co-authors conducted five studies to identify the conditions under which donors pledge higher amounts of money to recipients who are located spatially far away versus nearby recipients, and to rule out the possibility that the effect of spatial distance is driven by unequal economic conditions and, thus, differences in need between the two recipients.

"What we found is that people who donate money to causes that aren't local do so to feel more fulfilled, because it's something that's more aligned with their moral identity, which is the extent to which moral traits, goals and behaviors are important to one's self-concept or self-identity," said Torelli, also the executive director of Executive and Professional Education at the Gies College of Business. "We also found that this positive effect was more prevalent among people high in moral self-concept and was attenuated or even reversed among people low in moral self-concept."

The appeal to morality in requesting donations for distant recipients is "an entirely different framework" than for requesting donations to a local cause, which should emphasize the concrete, actionable impact of a monetary donation, Torelli said.

"For local or nearby causes, you really have to push the immediate impact aspect of it - how many people you can help, how much and how quickly your dollar can be put to work for individuals who are members of the community," he said. "The morality appeal, on the other hand, really has to tap into higher-level idealistic goals - clean water for everyone the alleviation of hunger, for example."

The paper's findings can help organizations increase the efficacy of marketing initiatives, Torelli said.

"The same cause can use different appeals depending on who they're targeting and where they are," he said. "If they're far away, then an appeal to morality is going to be more effective than an appeal to sheer numbers and impact."

The research also has implications for for-profit organizations engaging in corporate social-responsibility initiatives.

"Many large organizations are global and choose international charitable organizations to partner with, to align their social impact with their practices and beliefs," Torelli said. "Not only does this type of initiative have a social impact, it can also have a positive impact on employees of the organization. Our findings suggest that companies with corporate social-responsibility initiatives that help recipients in distant locations could benefit by focusing their communications on the higher-level goals that such initiatives are accomplishing instead of just touting their impact.

"Doing so might result in higher employee involvement with the charitable cause and higher employee satisfaction, particularly for employees who place a lot of importance on moral identity."

"Running in Tarahumara (Rarámuri) Culture," just published in Current Anthropology (v61, no. 3 (June 2020): 356-379) studies the Tarahumara Native Americans of northern Mexico. For over a century, the Tarahumara have been famous for their long distance running traditions and abilities, with many accounts claiming they have superhuman athletic abilities that partly result from being uncontaminated by westernization. Now an international team of researchers (including a champion Tarahumara runner) combine their own observations with detailed interviews of elderly Tarahumara runners to dispel these stereotypical myths, which they term the "fallacy of the athletic savage." Lieberman and colleagues use accounts by Tarahumara runners to detail the various ways Tarahumara used to run for hours to hunt animals, and they describe how the Tarahumara still run traditional long distance races that, for men, involve chasing a small wooden ball and, for women, a hoop. While these many different kinds of running have important social dimensions, running is also a spiritually vital form of prayer for the Tarahumara. Further, contrary to the fallacy of the athletic savage, Tarahumara runners --both men and women-- struggle just as much as runners from other cultures to run long distances, and instead of being the natural "superathletes" that some journalists have claimed, they develop their endurance from regular hard work and other endurance physical activities such as lots of walking and dancing.
