BLOOMINGTON, Ind. – In the classic Disney film “Beauty and the Beast,” Lumière, the candelabra character, famously sings with Mrs. Potts, a tea pot, “Be our guest, be our guest. Put our service to the test. Tie your napkin round your neck, Cherie, and we provide the rest.”

When the 1991 Oscar-nominated song co-written by Indiana University alumnus Howard Ashman was released, it hardly seemed realistic that a product could sing its own praises and sell itself to consumers. But artificial intelligence today makes it possible and new research from the IU Kelley School of Business finds that it can be a winning retail strategy.

Alan Dennis, professor of information systems and the John T. Chambers Chair of Internet Systems at the Kelley School, believes that it won’t long before products are selling themselves. Visual design technologies have rapidly improved over the past decade. Digital assistants such as Siri and Alexa and support chatbots have become ubiquitous.

“Companies have long used cartoon-like characters to sell products. We are familiar with the ‘M&M spokescandies,’ for example,” Dennis said. “But adding human features to a product can be a powerful way to influence consumers’ perceptions and decision making, because it can trigger anthromorphism.

“When we hear or see an inanimate object that has human features, our brain automatically ascribes human form to it even though we rationally know the object is not human. Anthromorphism changes how we think and behave toward an object, making us like it more,” he added. “Initial evidence suggests that not all products can trigger this; people are more likely to anthromorphize complex products.”

To test this idea, Dennis asked about 50 undergraduate students to assume the role of a new master’s candidate and told them their program required them to purchase a laptop computer, a camera and a television. They were required to bid for the products in an eBay-style auction site.

The researchers used a two-minute video to deliver the “human” element of each product and participants couldn’t bid until it was finished. They used a professional graphic to add human physical characteristics – such as eyes, a mouth and nose – human-like movements – such as blinking and mouth movement while talking. Each product spoke in the first person.

In addition to tracking each person’s willingness to pay, their cognitive processes were measured using an Emotiv EPOC EEG headset. Findings included:

  • People were willing to bid about 20 percent more for the more complex product – the laptop – when it was displayed with the human attributes, as compared with those who only learned about it through a static web page or with a video presenting just a slideshow.
  • In contrast, displaying the less complex products – the television and camera – in the same anthromorphic way had no effect on the amount bid.
  • The EEG data showed that presenting a product with the human elements and features triggered more cognition in the parietal lobe of the brain, which plays a key role in our understanding of the world around us. It also helps us understand where we are in relation to other things that your senses detect around us.
  • This recognition within brain was not a universal response. The data showed that ascribing human characteristics to the non-human products triggered different responses, depending the complexity of the product. Many respondents exerted more effort to suppress the “cartoon agent” as irrelevant in the case of the television and the camera.
  • The results suggest that people are more likely to amthromophize a product if it already has some human-like functionalities, such as the ability to respond and speak in a human voice, present some level of human knowledge, or have some autonomy in how it functions.

“Our research shows that there are important boundary conditions in the effects of displaying products in an anthromorphic form,” Dennis said. “Our results show that anthromorphic displays lead to different cognition and different willingness to pay for more complex products, but not less complex products … Our results suggest that adding a face, movement and human speech are useful in designing the display of more complex products.”

The paper, “Selling myself: Anthropomorphic products in electronic commerce,” appears in the journal, Decision Support Systems,” and was co-authored by Dennis and Lingyao “Ivy” Yuan, associate professor of information systems and the Kingland Systems Graduate Director of Business Analytics at the Debbie and Jerry Ivy College of Business at Iowa State University. She earned her PhD in information systems from the Kelley School of Business.

Subjects were shown products with human physical characteristics – such as eyes, a mouth and nose – that talked about their features.

Cuts to fire protection funding initially have a larger effect on home prices than crime, school quality or environmental quality, but the short-term decreases don’t persist, University of Cincinnati economists found.

David Brasington, PhD, and Olivier Parent, PhD, professors of economics in UC's Carl H. Lindner College of Business, studied the effects of communities that don’t pass fire protection renewal levies on housing values for a research article that was published in the journal Regional Science and Urban Economics.

Brasington was surprised by how cuts to fire protection funding had a greater effect on housing prices than other factors.

“We were really surprised about it having an effect and the magnitude of the effect, too,” he said. “It was surprising to me, also, because schools get the bulk of funding, and police services are so important.”

To study the effects of funding cuts, Brasington and Parent analyzed data of house sales in Ohio between 1995-2006, the most recent time frame that data was available.

They focused on communities that according to the U.S. Census Bureau share similar demographic and economic characteristics. The only discernible difference was that some of them narrowly voted to renew tax levies while others narrowly voted against renewing their levies.

In the year after communities narrowly voted to cut fire protection funding, house prices dropped between 6.7% and 15.1%. That translates to an average decrease in house values of $15,000 while the tax savings for the life of the house is only $1,500.

“Not renewing is kind of a shock to the community,” said Brasington, who added it’s rare for Ohio communities to vote against fire protection levies.

While housing prices decreased after a failed fire protection levy, Parent and Brasington found the prices returned to their normal levels in those communities within a few years.

“There might be some effect the second year after the vote but then normal levels return,” Brasington said. “You can’t tell a difference in house prices in cities that vote against the tax levies the third year, fourth year or fifth year after the vote. But there’s a temporary blip in house prices.

“Our guess is that a big factor in the drop of house prices initially is fear, fear of increased risk of fire. But what happens in Ohio is every fire department supports the other. If there’s a fire in [one area], the fire departments from [neighboring communities] and anywhere close by send fire trucks to help each other through mutual assistance agreements. The actual protection from fires is good, even if a tax levy fails probably because of these mutual assistance agreements.

“Our guess is people are afraid of the decrease in services at first then after a couple years they realize, ‘Well, there hasn’t been any big change in actual fire protection.’”

The effects of fire protection cuts are the opposite of cuts to park funding, which Brasington previously studied.

Brasington found Ohio communities that vote to renew parks and recreation spending see 13% higher home values three years after the vote than similar communities that voted against the tax renewals. While cuts to park funding initially didn’t have an effect on house prices, the effects grew in the following years.

“The parks and recreation cuts take a while to be noticeable whereas the fire protection failure drops house prices right away but doesn’t persist,” Brasington said. “They’re like the opposite sides of a coin.”

For both parks and fire protection, Brasington said, the studies show that those services matter to residents and are worth the investment.

 

Wildfires linked to surge in mental health-related emergency department visits


Peer-Reviewed Publication

EMORY HEALTH SCIENCES




An Emory University study published Feb. 15 in Nature Mental Health shows wildfires lead to an increase of anxiety-related emergency department visits in the western United States, amplifying the concerning parallel trajectory of two escalating public health crises — mental health and climate change.

The National Institutes of Health-funded study — conducted by researchers at Emory’s Rollins School of Public Health — is among the largest and most comprehensive research ever undertaken on the association between wildfire-related exposures and anxiety disorders.

Analyzing satellite-driven data and nearly 1.9 million emergency department visits across five states (California, Arizona, Nevada, Oregon and Utah) from 2007-18, the researchers showed wildfire smoke events — which is when wildfires become the main source of ambient pollution within a ZIP code — were associated with a 6.3% increase in mental health-related emergency department visits.

In addition to this startling data, the study shows:

  • Women, girls and older adults are more susceptible to severe anxiety disorders associated with wildfire exposures.
  • Men and boys also experienced an increase in anxiety disorders but only when linked to major smoke events.
  • Evidence for enhanced disaster risk reduction and climate risk management strategies, including climate awareness and risk communication tailored for vulnerable populations.

What the researchers say:

“The scary thing about climate change is it doesn’t have a clear boundary; you fear a lot about the unknown. Now we can use the knowledge we’ve gained to tell people there is no need to panic. When you receive a wildfire smoke alert, close your windows, limit your outdoor activities and don’t panic. Those sorts of preventative measures can potentially benefit the entire population,” says study co-author Yang Liu, PhD, chair and Gangarosa Distinguished Professor in the Gangarosa Department of Environmental Health at Rollins.

“Mental health is one of the most prevalent health conditions in the U.S. and our study found multiple pathways between wildfires and an association with severe anxiety disorders. Many people are already dealing with some mild or moderate mental health symptoms. Now imagine they wake up and see the sky covered in smoke, they’re likely going to feel even more anxious,” says the study’s lead author Qingyang Zhu, PhD, a postdoctoral fellow in the Gangarosa Department of Environmental Health.

Why it matters:

  • Rising temperatures and shifting drying patterns substantially escalated the potential for wildfires globally over the past 20 years, resulting in expanded burned areas and prolonged fire seasons.
  • The western United States is notoriously a major fire-prone region, due to the recurrent presence of fire weather conditions, increasing droughts and the abundance of fuel resources.
  • Climate change has been linked to a variety of psychological disorders such as anxiety, depression, post-traumatic stress disorder and eating disorders.
  • Mental health disorders, including anxiety disorders, have been an increasing threat to global public health in the past three decades. According to the most recent Global Burden of Disease study released in 2020, anxiety disorder was the 24th leading contributor — out of 369 diseases — to the global burden of disease.

This research was supported by the National Institute of Environmental Health Sciences of the NIH (ES034175 and ES027892). The NIH has established an NIH Climate Change and Health Initiative to reduce health threats from climate change, including mental health.

In a world where human activities have left an indelible mark on ecosystems, the preservation of species and natural landscapes has become an urgent global concern. Despite such trends, Traditional taboos rooted in religious beliefs have sometimes served as influential mechanisms for species conservation. Sociocultural systems have established sacred natural sites as an asylum with their rich biodiversity. Yet, research on species within these sites unveils conflicts between societal values and the imperative for nature conservation.

 

The case of Nara in Japan, where the sacred sika deer have been protected for over a thousand years, illustrates the complexities of wildlife management under cultural protection. Initially, the deer population was confined within traditional sanctuaries, but over 50 years of intensive protection policies have led to a rapid increase in numbers, causing them to spill out of these areas. Additionally, in the last 20 years, deer populations have surged in surrounding regions, previously almost devoid of deer. These include deer born outside the sanctuaries, now encroaching on the traditional protected areas.

 

For local farmers, preventing agricultural damage caused by these increasing numbers is a significant challenge. However, legal constraints and psychological resistance make culling, a common approach in other regions, difficult to implement in Nara. As this delicate balance between traditional protection and modern livelihoods is tested, the city of Nara has implemented wildlife management strategies, dividing the Nara city into protected, management and buffer areas. Despite these efforts, however, the escalating deer population has persisted, demanding a more scientific approach and a comprehensive plan to deal with the growing deer population.

In response to this pressing issue, researchers from Fukushima University undertook a genetic study and delving into the intricate genetic composition of the sacred deer population. “Our primary objective was to unveil potential impacts on the distinct genetic identity of the sacred deer, offering crucial insights that extend beyond genetics. The broader implication of the study was to explore wildlife management challenges and address overarching conservation issues,” explains Associate Professor Shingo Kaneko from the Faculty of Symbiotic Systems Science, Fukushima University, who, along with his colleague Dr. Toshihito Takagi and their team conducted the study. Their findings were published in the Journal of Conservation Science and Practice.

The team started by collecting samples from nine sites in districts A, B, and D of Nara city, comprising a total of 165 deer specimens. Genetic analysis focusing on the mitochondrial DNA (mtDNA) control region and nuclear simple sequence repeat (SSR) markers revealed a spatial pattern in the distribution of genetic variations among the studied deer populations. In the protected area, there was a dominance of a single mtDNA haplotype labeled as S4. However, in the management area, there were multiple haplotypes.

 

In terms of nuclear SSR, higher genetic diversity was observed in the management area compared to that in the protected region. The genetic structure and admixture analysis revealed two distinct clusters, with Cluster 1 dominant in the protected area and Cluster 1 and 2 mixed in the management region. "The protected region, dominated by the exclusive S4 mtDNA haplotype, reflects their historical isolation. In contrast, the management area showcases the establishment of genetically distinct populations, suggesting interbreeding and the potential replacement of the sacred deer by ordinary deer,” observes Dr. Takagi.

 

The coexistence and admixture context present challenges in deciding conservation policies, posing a dilemma between preserving the sacred deer lineage and allowing admixture for avoiding extermination.

 

The urgency in addressing these conflicts is underscored by concerns such as increased damage to agriculture, loss of genetic specificity, and potential disease spread. The study emphasizes the need for reconciliation and agreement on values among stakeholders based on scientific analysis, considering broader socio-economic, ecological, and cultural conditions. Public health concerns, including zoonosis and tick-borne diseases, further highlight the importance of careful management in this unique context, where the conservation of a population with a millennium-long history is at stake.

Until now, research results from population genetic analysis have rarely been utilized in Japanese wildlife management field. However, with the publication of our genetic research on ‘Deer of Nara,’ which is familiar to Japanese people, genetic analysis will likely be widely used to evaluate the origin of animals of unknown origin and the admixture of populations,” states a hopeful Dr. Kaneko.

The findings of this study will not only inform conservation and management strategies for Nara's sacred deer but also contribute to a global dialogue on balancing human-wildlife interactions in the face of rapid environmental changes.

Concordia researchers identify a decline in microbial genetic richness in the western Arctic Ocean


Small but statistically significant results point to the need for future study, say David Walsh and Arthi Ramachandran

The Arctic region is experiencing climate change at a much faster rate than the rest of the world. Melting ice sheets, runoff from thawing permafrost and other factors are rapidly changing the composition of the Arctic Ocean’s water. And that change is being experienced all the way down to the microbial level.

In a Concordia-led study published in the journal ISME Communications, researchers analyzed archival samples of bacteria and archaea populations taken from the Beaufort Sea, bordering northwest Canada and Alaska. The samples were collected between 2004 and 2012, a period that included two years — 2007 and 2012 — in which the sea ice coverage was historically low. The researchers looked at samples taken from three levels of water: the summer mixed layer, the upper Arctic water below it and the Pacific-origin water at the deepest level.

The study examined the microbes’ genetic composition using bioinformatics and statistical analysis across the nine-year time span. Using this data, the researchers were able to see how changing environmental conditions were influencing the organisms’ structure and function.

The researchers found subtle but statistically significant changes in the communities they studied.

“We observed a general overall loss in diversity of species across all the different water masses,” says David Walsh, a professor in the Department of Biology and the paper’s corresponding author.

“We also saw changes in the composition of the microbial community, meaning there were different species after the 2007 sea ice minimum than before.”

However, the periods of population richness decline changed between the ocean’s layers of water. Sudden decline in the fresher summer mixed water level, between 3–9 meters deep, was observed in 2005–2007. The upper Arctic water, between 16–78 metres, saw declines in 2010–2012, while the deeper Pacific water layer, between 49–154 meters, experienced a two-step decline — once between 2005–2007 and again between 2010–2012.

Small beginnings

The researchers are taking care not to overemphasize the results of their findings, saying the changes, while significant, remain slight. But with the summer Arctic ice cover shrinking steadily year over year, the data does hint at possible trends that may be visible in upcoming population studies in more recent years.

“With the warming and freshening of the Arctic Ocean comes a decrease of nutrients that are important for photosynthesis, which produces the organic matter that serves as energy and carbon sources for the marine food web,” Walsh explains.

“This shift risks strengthening what is known as the microbial loop, in which the energy and carbon that would normally go into higher trophic levels — meaning zooplankton and then fish — is rapidly recycled by microorganisms. This ecosystem is already dominated by microbial processes, which will only get stronger as this system continues.”

“This study provides us with a baseline idea of what is happening in the Arctic,” says co-author Arthi Ramachandran, PhD 23. “The Arctic is warming four times faster than the rest of the world, which makes it a fascinating ecosystem to study. The oceans are all interconnected, and the physical barriers of these oceans are becoming much less defined.”

Looking into the ocean’s warmer, fresher future

The researchers are now planning a metagenomic study that extends the time series to cover periods of even more intense sea ice minima. They hope to fully sequence the organisms’ genomes to further understand the microbial communities’ diversity and function in the environment.

The paper’s other co-authors are PhD candidate Vera Onana, Susanne Kraemer of Environment and Climate Change Canada and William Li of the Fisheries and Oceans Canada.

Energy poverty in Canada


An overlooked health and equity issue

Peer-Reviewed Publication

MCGILL UNIVERSITY




As many as one in five Canadian households can be considered to be in energy poverty, according to researchers from McGill University. Energy poverty occurs when households cannot afford or access the levels of energy necessary to meet their daily needs, live decent lives, and maintain healthy indoor temperatures all year round. More Canadians potentially suffer from energy poverty than from food insecurity.

Energy poverty as a predictor of poor health

“Earlier research has shown that a cold indoor temperature is associated with an exacerbation of some chronic diseases, so energy poverty is cause for concern,” says Mylène Riva, the Canada Research Chair in Housing, Community and Health, an associate professor in the Department of Geography and the senior author on a recent study in The Canadian Journal of Public Health. “In another study we are conducting in a small town in rural Canada, as many as 8% of participants reported having seen their breath inside their homes in winter.”

Indeed, the researchers found that, compared to those who were able to access and afford the energy services they needed, energy poverty was associated with a greater likelihood of poorer self-rated general and mental health. These factors are known to be strong predictors of higher levels of illness, and an increased risk of hospitalization and death. 

Higher levels of energy poverty in rural areas

The research also shows that there are higher levels of energy poverty in rural areas in Canada, where the population tends to be older, living in larger households, and facing greater income insecurity.

“For example, we found that in a small town in Nova Scotia, where around 40% of the population faces energy poverty, one household in three reported having to cut into their grocery spending to pay their utility bills,” adds Laurianne Debanné, a PhD student in Health Geography at McGill who has been studying energy poverty in Bridgewater, Nova Scotia, for the past three years.

Current Canadian energy efficiency programs failing to address energy insecurity

The researchers highlight the fact that programs and policies to advance energy transition—for example, those targeting energy efficiency in the housing sector—tend to be accessible to homeowners rather than renters and could potentially create or exacerbate social and health inequities if their benefits are not distributed equitably across the population.

“Households facing energy poverty start at a disadvantage in the energy transition. To prevent and reduce energy poverty and increase energy security across the country, programs and policies should address the main drivers of energy poverty, factors such as dwelling conditions and their energy efficiency, lower incomes, and the energy costs borne by ratepayers and end-users,” says Riva.

“Given the high proportion of Canadian households facing energy poverty, with demonstrated implications for population health, the results from this study make a strong case for energy poverty to be included in discussions about a just energy transition towards future climate resilience in Canada.”

The study was based on self-reported data from the 2018 Canadian Housing Survey, on a sample weighted to represent 14 million Canadian households from both rural and urban areas.

Energy poverty: an overlooked determinant of health and climate resilience in Canada” by Mylène Riva et al was published in the Canadian Journal of Public Health.

Health care inequities behind shorter life spans for Inuit from Nunavik, Quebec, with lung cancer


Peer-Reviewed Publication

CANADIAN MEDICAL ASSOCIATION JOURNAL





People living in the Inuit region of Nunavik in northern Quebec die earlier after a diagnosis of lung cancer than Montreal residents receiving treatment at the same cancer centre, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.230682.

All inhabitants of Nunavik are investigated and treated for cancer at the McGill University Health Centre (MUHC) in Montreal, more than 1400 km away from Nunavik hospitals, due to limited resources in the region. 

Researchers compared lung cancer survival between 95 Nunavik and 185 Montreal residents being treated at MUHC. They found that Nunavik residents with similar stages of lung cancer had shorter survival than Montreal residents, even after accounting for other differences between the groups. 

Analyzing results with community representatives pointed to chronic health care under-resourcing as a possible root cause of these survival differences.

"We underscore that our results should not be interpreted to conclude that Inuit have a genetic predisposition to worse lung cancer outcomes. Rather, our study observations contextualized with other knowledge about health services and access in Nunavik point to chronic underfunding and under-resourcing of Nunavik's health care services, as well as the lack of Inuit representation in health care provision, as likely upstream determinants of the disparity observed in our study," writes Dr. Faiz Ahmad Khan, a respirologist and associate professor, MUHC, Montreal, Quebec, with coauthors.

The authors recommend several actions to improve lung cancer survival for Nunavik Inuit, including:

  • Deploying Inuit-specific smoking cessation and prevention services
  • Making lung cancer screening available immediately, in an accessible, acceptable and culturally safe format, to facilitate earlier detection of lung cancer
  • Improving lung health services by, for example, creating x-ray capacity in villages
  • Supporting a Nunavik Inuit-specific lung cancer care plan
  • Providing training and employment for Inuit health navigators to support patients and families in Montreal
  • Increasing funding and human resourcing to strengthen Nunavik health care services

"In the bigger picture, observations such as ours should support Nunavik Inuit efforts toward greater self-governance, as increased Inuit decision-making over health care policy and funding will help ensure health services are aligned with the population's needs."
