Study underscores lack of diversity in stock photography sites

Peer-Reviewed Publication

NORTH CAROLINA STATE UNIVERSITY


A new study finds the majority of images related to health topics on stock photography sites are of light-skinned people within a fairly narrow age range, making it more difficult – and expensive – for organizations to create health education materials aimed at reaching other groups.

The findings are significant because using images relevant to audiences is an important factor in successful communication and outreach efforts. If many populations are not well represented on stock photography sites, it’s more difficult to develop effective communication tools to reach those populations.

“Many organizations that produce health outreach materials rely on stock photography sites to produce those materials,” says Michelle Jewell, co-author of the study and a science communicator in the Department of Applied Ecology at North Carolina State University. “In many cases, organizations that create outreach materials for minoritized groups or populations with lower socioeconomic status have limited resources, which exacerbates the challenges they face in producing effective materials that reflect the publics they serve.”

The researchers also found a significant difference between the diversity present on images available on free stock photography sites versus on sites that require users to pay for stock photos.

“Images on stock photo sites with paywalls were significantly more likely to depict a person of perceived minoritized racial/ethnic identity and darker skin tones,” says Catherine LePrevost, co-author of the study and an associate extension professor of applied ecology at NC State. “The pay sites were also less likely to contain markers of high socioeconomic status than images in databases that were free to use.”

“In other words, it is harder to find health-relevant photos of people who are not light-skinned and upper class,” Jewell says. “And when you do find them, they are more likely to come with a fee.”

The researchers launched the study after they struggled to find a stock image of a Latina pregnant woman for an unrelated science communication effort.

“Anecdotally, this lack of representation in stock photography is a widely known problem among professional communicators,” Jewell says. “We wanted to quantify the problem to get a better understanding of the scope of the problem.”

For the study, the researchers focused on five widely used stock image libraries, and searched each of those sites for five health-related terms: healthy eating, exercising, quitting smoking, vaccination, and pregnancy.

While about half of the images the researchers found included at least one person from a perceived minoritized group, there were stark differences when researchers accounted for skin tone.

For some search terms – healthy diet and quitting smoking – there were no images of people with dark skin tones at all. Only one search term – vaccination – included dark skin tones in 20% of its images.

“It became glaringly evident while searching through the stock photo libraries that certain populations are underrepresented,” say Zachary Chichester, first author of the study and an undergraduate at East Carolina University at the time of the study. “It is imperative that we bring attention to this issue in order to ensure that creators of health education media are able to produce materials that are most effective.”

Another factor was whether the stock photos showed a person’s face.

“If you were looking for photos that included someone’s face, which is important for humanizing the subject matter, things became even more difficult,” LePrevost says. “Basically, if an image included a person’s face, it was much less likely to be someone who could be recognized as being part of a minoritized racial or ethnic group.”

Age presented another challenge, with the researchers finding very few images that included older adults of any racial or ethnic group.

And these disparities became more pronounced when looking only at free stock photo sites and images.

“Effective health communication is incredibly important, and our study outlines a systemic obstacle to developing health communication tools for many groups,” LePrevost says. “Communication is an important component in addressing health disparities, and this work highlights one of the challenges facing those communication efforts.”

“We also hope this work will help health communicators secure the time and financial resources they need in order to develop effective outreach tools,” Jewell says. “Organizations that support health communication and education efforts need to recognize that communicators don’t have access to free images that are relevant to many audiences. Moving forward, granting bodies and other revenue sources should include budgets for photographers and illustrators to create media that best represents relevant audiences.”

New Mexico’s largest emitters overlooked in state climate policy

Well-designed climate policies could reduce climate- and health-damaging air pollution from large stationary sources responsible for 25 percent of state’s greenhouse gas emissions

Reports and Proceedings

PSE HEALTHY ENERGY

ALBUQUERQUE, NM — Many of New Mexico’s largest sources of climate and health-damaging air pollutants are not required to cut emissions at rates necessary to meet the state’s climate targets, according to a new analysis from researchers at the University of New Mexico and PSE Healthy Energy.

“We found that the state’s existing climate policies don’t require sufficient reductions from many of the large sources responsible for a quarter of the state’s emissions,” said Gabriel Pacyniak, associate professor of Law at University of New Mexico. “This puts climate goals at risk and has significant impacts for public health.”

The report analyzed emissions of health-damaging air pollutants and greenhouse gasses from 189 large stationary sources of pollution across New Mexico. Collectively, the sources reported 31.4 million metric tons of carbon dioxide equivalent (MTCO2e) in 2019, or approximately 25 percent of the state’s total greenhouse gas emissions in 2018. These same sources likely contribute the largest share of sulfur dioxide emissions in the state and a substantial share of nitrous oxides, both potent health-damaging air pollutants.

“As New Mexico retires its large coal plants, the relative share of emissions from the oil and gas sector continues to grow,” said Angélica Ruiz, environmental health analyst at PSE Healthy Energy. “By lowering emissions at facilities that pose the greatest risk to public health, we can dramatically increase the benefits of climate policies.”

The report also analyzed where large sources are located and suggested that there may be equity benefits to reducing emissions in those areas with a high percentage of people of color, lower-income people, or people with health vulnerabilities. Four regions—the San Juan Basin; Permian Basin; Albuquerque, Bernalillo, and Sandoval Counties; and Las Cruces and Dona Aña County—were identified as areas with particularly high concentrations of large stationary emissions sources.

“This report underscores that many Native, Latino, Black, and low-income communities bear substantial pollution burdens,” said Shannon Sanchez-Youngman, assistant professor at the UNM College of Population Health. “It’s crucial that these communities have a meaningful opportunity to participate in policy making processes.”

Climate policies that focus solely on achieving aggregate greenhouse gas emission reductions can allow health-damaging air pollution to persist. With New Mexico’s goal of reducing greenhouse gas emissions by 45 percent by 2030, this report offers analysis and policy recommendations to maximize the public health and climate benefits of state policies.

“Climate policies designed in parallel with air pollution policies can simultaneously reduce climate pollution and improve public health,” said Dr. Elena Krieger, director of research at PSE Healthy Energy. “But addressing climate emissions alone will likely not achieve the greatest public health benefits.”

The Center for Civic Policy served as the fiscal sponsor and advisor of the report, and the report was funded by the Environmental Defense Fund.

An analysis of nearly 2 million Tweets made by people in London and San Francisco explores specific events and types of locations that are associated with different emotions. Panote Siriaraya of the Kyoto Institute of Technology, Japan, and colleagues present these findings in the open-access journal PLOS ONE on February 1, 2023.

A growing body of research examines social media posts and location data to explore human behavior and emotions; for instance, to compare levels of happiness between geographic regions. However, much of that work has been limited to larger geographic scales and is focused on just one emotion at a time, or on a general assessment of positive versus negative emotion.

Siriaraya and colleagues now demonstrate how human emotional expression can be explored at a finer-grained level using Tweets and information on specific buildings, businesses, and other locations of interest from the public platform Open Street Map. They used computational tools known as neural networks to analyze nearly 2 million Tweets made by more than 200,000 people in London and San Francisco, identifying when and where people expressed anger, anticipation, disgust, fear, joy, sadness, surprise, or trust.

The analysis showed that different location types were associated with expression of different emotions. For instance, in both cities, tweets made in train stations, bridges, and other transportation sites tended to express less joy and more disgust. Tweets from hotels and restaurants showed higher levels of joy. Additionally, proximity to certain sites—and not just being within the sites—was associated with a difference in expressed emotions.

Specific events appeared associated with higher levels of specific emotions; for instance, San Francisco users displayed their highest levels of anger, disgust, and sadness on the day of the 2017 Women’s March, and London users showed high levels of fear and sadness during two local terrorism attacks. New Year’s Eve coincided with high levels of joy in both cities.

The researchers caution against overgeneralizing their results; for instance, the study only included Tweets in English. Nonetheless, they could help pave the way to additional fine-grained research to inform such fields as urban planning and tourism.

The authors add: “Our study highlights how it is possible to portray the characteristics of fine-grained emotions at a detailed spatial and temporal level throughout the whole city, using publicly available data sources.”

First solid scientific evidence that Vikings brought animals to Britain

Archaeologists have found what they say is the first solid scientific evidence suggesting that Vikings crossed the North Sea to Britain with dogs and horses.

Research led by Durham University, UK, and the Vrije Universiteit Brussels, Belgium, examined human and animal remains from Britain’s only known Viking cremation cemetery at Heath Wood, in Derbyshire.

Scientists looked at strontium isotopes contained within the remains. Strontium is a natural element found in different ratios across the world and provides a geographical fingerprint for human and animal movements.

Their analysis showed that within the context of the archaeology, one human adult and several animals almost certainly came from the Baltic Shield area of Scandinavia, covering Norway and central and northern Sweden, and died soon after arrival in Britain.

The researchers say this suggests that Vikings were not only stealing animals when they arrived in Britain, as accounts from the time describe, but were also transporting animals from Scandinavia, too.

As the human and animal remains were found in the remnants of the same cremation pyre, the researchers believe the adult from the Baltic Shield region may have been someone important who was able to bring a horse and dog to Britain.

The analysed remains are associated with the Viking Great Army, a combined force of Scandinavian warriors that invaded Britain in AD 865.

The findings are published in the scientific journal PLOS ONE.

Lead author Tessi Löffelmann, a doctoral researcher jointly working in the Department of Archaeology, Durham University, and the Department of Chemistry, Vrije Universiteit Brussels, said: “This is the first solid scientific evidence that Scandinavians almost certainly crossed the North Sea with horses, dogs and possibly other animals as early as the ninth century AD and could deepen our knowledge of the Viking Great Army.

“Our most important primary source, the Anglo-Saxon Chronicle, states that the Vikings were taking horses from the locals in East Anglia when they first arrived, but this was clearly not the whole story, and they most likely transported animals alongside people on ships.

“This also raises questions about the importance of specific animals to the Vikings.”

The researchers analysed strontium ratios in the remains of two adults, one child and three animals from the Heath Wood site.

Strontium occurs naturally in the environment in rocks, soil and water before making its way into plants. When humans and animals eat those plants, strontium replaces calcium in their bones and teeth.

As strontium ratios vary in different parts of world the geographical fingerprint of the element found in human or animal remains can help show where they came from or settled.

Strontium ratios in one of the adults and the child showed that they could have been from the area local to the Heath Wood cremation site, southern or eastern England or from Europe, including Denmark and south-west Sweden which were outside of the Baltic Shield region.

But the remains of the other adult and all three animals – a horse, a dog and what the archaeologists say was possibly a pig – had strontium ratios normally found in the Baltic Shield area.

While the researchers say their findings suggest the horse and dog were transported to Britain, it may be that the pig fragment was a piece from a game or another talisman or token brought from Scandinavia, rather than a live pig. The remains had also been cremated and buried under a mound, which the researchers say could be a link back to Scandinavian rituals at a time when cremation was absent in Britain.

Research co-author Professor Janet Montgomery, in the Department of Archaeology, Durham University, said: “Our study suggests that there are people and animals with different mobility histories buried at Heath Wood, and that, if they belonged to the Viking Great Army, it was made up of people from different parts of Scandinavia or the British Isles.

“This is also the first published strontium analysis on early medieval cremated remains from Britain and shows the potential that this scientific method has to shed further light on this period in history.”

The research team also included archaeologists from the University of York, UK, who excavated the Heath Wood cemetery between 1998 and 2000, and the Université Libre de Bruxelles, Belgium.

Professor Julian Richards, of the Department of Archaeology, University of York, who co-directed the excavations at the Heath Wood Viking cemetery, said: “The Bayeux Tapestry depicts Norman cavalry disembarking horses from their fleet before the Battle of Hastings, but this is the first scientific demonstration that Viking warriors were transporting horses to England two hundred years earlier.

“It shows how much Viking leaders valued their personal horses and hounds that they brought them from Scandinavia, and that the animals were sacrificed to be buried with their owners.”

The research was funded by Arts and Humanities Research Council (Northern Bridge) funding, the Vrije Universiteit Brussels, and The Rosemary Cramp Fund and the Institute of Medieval and Early Modern Studies, both Durham University.
