Racial makeup of private prisons shows disparities, new OSU study finds

CORVALLIS, Ore. – A disproportionate number of Hispanics are housed in private prisons across the United States, a pattern that could leave such prisons vulnerable to legal challenges, new research from Oregon State University shows.

The percentage of adult Hispanic inmates in private prisons was two points higher than those in public facilities, while the percentage of white inmates in private prisons was eight points lower than in public facilities, said Brett Burkhardt, an assistant professor of sociology in the School of Public Policy at OSU’s College of Liberal Arts.

“This is a systemic issue,” Burkhardt said. “Prison administrators should be aware of racial disparities in inmate placement to ensure that inmates’ rights are being upheld and to avoid future lawsuits.”

Private prisons are those operated by private for-profit or non-profit companies that have contracts with government agencies. In some cases, the private company operates an existing prison, while in others the company builds and operates the facility. About 8 percent of those sentenced to state or federal prison are being held in private facilities, according to a 2011 study.

But there are some concerns that those in private prisons have fewer opportunities for jobs and rehabilitation and are more likely to get in trouble while incarcerated, which could raise questions about whether private prisons provide inmates equal protection under U.S. civil rights laws.

Research has shown that private prisons have higher rates of inmate misconduct; fewer work assignments for prisoners; more inmate grievances; and more escapes than public facilities, Burkhardt said. 

“The data can’t demonstrate that there is a violation of inmates’ rights,” Burkhardt said. “But prison officials should be aware of the pattern because it could trigger lawsuits.”

Burkhardt’s study is the latest in a growing body of research on racial disparities in the criminal justice system. African-Americans and Hispanics are incarcerated at much higher rates than whites in the U.S. and previous research has found widespread racial disparities throughout the criminal justice system.

The disparity in prison placement is not linked to higher overall incarceration rates of Hispanics. It appears to stem from the process in which inmates are assigned to a correctional facility, Burkhardt said. How those decisions are made is unclear; they typically are handled by prison administrators. The research indicates there is a racial pattern to inmate assignment at correctional facilities, which also could raise legal concerns for corrections officials, he said.

Burkhardt’s findings were outlined in an article titled “Where Have All the (White and Hispanic) Inmates Gone? Comparing the Racial Composition of Private and Public Adult Correctional Facilities.” The article was recently published in the journal “Race and Justice.” The research was supported by OSU.

Burkhardt analyzed national correctional facility data for all state and federal correctional institutions from 2005, about 1,500 in all. Federal immigration detention facilities were excluded. He found that Hispanics were overrepresented and whites were underrepresented in private prison populations.

African-Americans also were overrepresented in private prisons, but the difference was not considered statistically significant, Burkhardt said. When populations of African-American and Hispanic inmates were combined, they were four percentage points higher in private facilities than in public ones, which was significant, Burkhardt said.

The racial disparity is present in both federal and state facilities and it does not appear to be connected to the security level, size or age of the facility, he said. More research is needed to determine why Hispanics are over-represented in the private prison population, he said. For example, private firms may prefer healthier inmates, which tend to be young, non-white inmates; or the assignments may be tied to prisoners’ gang affiliations.

“It’s not entirely obvious why this is happening,” Burkhardt said. “It’s a little bit of a mystery.”

Study: Young women with sexy social media photos seen as less competent

BEND, Ore. – Girls and young women who post sexy or revealing photos on social media sites such as Facebook are viewed by their female peers as less physically and socially attractive and less competent to perform tasks, a new study from Oregon State University indicates.

“This is a clear indictment of sexy social media photos,” said researcher Elizabeth Daniels, an assistant professor of psychology who studies the effect of media on girls’ body image. Daniels’ findings are based on an experiment she conducted using a fictitious Facebook profile.

“There is so much pressure on teen girls and young women to portray themselves as sexy, but sharing those sexy photos online may have more negative consequences than positive,” Daniels said.

Girls and young women are in a “no-win” situation when it comes to their Facebook photos, Daniels said. Those who post sexy photos may risk negative reactions from their peers, but those who post more wholesome photos may lose out on social rewards, including attention from boys and men, she said.

“Social media is where the youth are,” she said. “We need to understand what they’re doing online and how that affects their self-concept and their self-esteem.”

Daniels’ research was published today in the journal “Psychology of Popular Media Culture.” The article, titled “The price of sexy: Viewers’ perceptions of a sexualized versus non-sexualized Facebook profile photo,” was co-authored by Eileen L. Zurbriggen of the University of California, Santa Cruz.

Daniels conducted the research while on the faculty at OSU-Cascades and received two Circle of Excellence grants from OSU-Cascades to support the study. She is now an assistant professor of psychology at the University of Colorado in Colorado Springs.

For the study, Daniels created two mock Facebook profiles for the fictitious 20-year-old Amanda Johnson. In both versions, Amanda liked musicians such as Lady Gaga, books such as “Twilight,” and movies like “The Notebook,” that would be appropriate for a person her age.

The only difference between the two was the profile photo. The photos were actual high school senior portrait and prom photos of a real young woman who allowed the photos to be used for the experiment.

In the sexy photo, “Amanda” is wearing a low-cut red dress with a slit up one leg to mid-thigh and a visible garter belt. In the non-sexy photo, she’s wearing jeans, a short-sleeved shirt and a scarf draped around her neck, covering her chest. 

Study participants were 58 teen girls, ages 13-18, and 60 young adult women no longer in high school, ages 17-25. They were randomly assigned one of the profiles and asked questions based on that profile.

The participants were asked to assess Amanda’s physical attractiveness (I think she is pretty), social attractiveness (I think she could be a friend of mine), and task competence (I have confidence in her ability to get a job done) on a scale from 1-7, with one being strongly disagree and 7 being strongly agree.

In all three areas, the non-sexy profile scored higher, indicating that those who viewed that photo thought Amanda was prettier, more likely to make a good friend and more likely to complete a task. The largest difference was in the area of task competence, suggesting a young woman’s capabilities are really dinged by the sexy photo, Daniels said.

The research underscores the importance of helping children and young people understand the long-term consequences of their online posts, Daniels said. Parents, educators and other influential adults should have regular conversations about the implications of online behavior with teens and young adults, Daniels suggested.

“We really need to help youth understand this is a very public forum,” she said.

The research also highlights the need for more discussion about gender roles and attitudes, particularly regarding girls and young women, she said.

“Why is it we focus so heavily on girls’ appearances?” she said. “What does this tell us about gender? Those conversations should be part of everyday life.”

Daniels’ advice for girls and young women is to select social media photos that showcase their identity rather than her appearance, such as one from a trip or one that highlights participation in a sport or hobby.

“Don’t focus so heavily on appearance,” Daniels said. “Focus on who you are as a person and what you do in the world.”

OSU receives federal grant to study academic outcomes of Oregon’s English learners

CORVALLIS, Ore. – Oregon State University has won a grant of nearly $400,000 from the U.S. Department of Education to investigate what happens to Oregon students who begin school as English language learners.

Researchers will use the grant to examine the academic performance of current and former English language learners and determine how best to support their academic achievement, said Karen Thompson, an assistant professor in OSU’s College of Education, who will lead the study.

“Being able to see, over a long period of time, how a student is doing is very important,” Thompson said. “Some students might need ongoing assistance even after they are considered proficient in English, while others might achieve at very high levels.”

Students who do not speak English proficiently when they enter school are considered English language learners. When students master the language, they are no longer considered English language learners and are reclassified as English proficient students.

Some states continue to monitor former English language learners throughout their school careers, but until recently, Oregon has only monitored them for two years, as required by the federal government, Thompson said.

The grant, from the education department’s research arm, the Institute of Education Sciences, will give investigators the opportunity to assess the longer-term academic success of students who enter school as English language learners, including graduation rates, she said. Researchers will also collect and analyze data about how current and former English language learners are faring in different types of programs, including dual-language programs, which have greatly expanded in Oregon schools in recent years, Thompson said.

The grant runs from Aug. 1 through July 31, 2016. The Oregon Department of Education and WestEd, a nonprofit education research agency, are partnering with OSU on the project. David Bautista, an assistant superintendent at the Oregon Department of Education, will serve as co-principal investigator.

The three agencies have established the Oregon English Learner Alliance in an effort to improve educational outcomes for Oregon’s English language learners. The alliance is part of a larger effort by the Oregon Department of Education to improve educational outcomes for students learning English.

The number of English language learners in Oregon has grown dramatically over the last 20 years and now makes up about 10 percent of the state’s kindergarten- through 12th-grade population. The number of reclassified students also has grown, making it more important than ever to understand how those students do in school once they’re no longer receiving extra help to learn English, Thompson said.

If researchers identify areas where current and former English language learners do well, they want to examine practices in those classrooms or schools and share the best of them with other educators, Thompson said.

EDITOR'S NOTE: This work will be supported by U.S. Department of Education grant number R305H140072. The amount of federal funding is $399,928, the non-federal funding for the project is $29,009 and the project’s total funding is $428,937. Of the total funding, 93 percent is federal and 7 percent is non-federal.

Iron, steel in hatcheries may distort magnetic “map sense” of steelhead

CORVALLIS, Ore. – Exposure to iron pipes and steel rebar, such as the materials found in most hatcheries, affects the navigation ability of young steelhead trout by altering the important magnetic “map sense” they need for migration, according to new research from Oregon State University.

The exposure to iron and steel distorts the magnetic field around the fish, affecting their ability to navigate, said Nathan Putman, who led the study while working as a postdoctoral researcher in the Department of Fisheries and Wildlife, part of OSU’s College of Agricultural Sciences.

Just last year Putman and other researchers presented evidence of a correlation between the oceanic migration patterns of salmon and drift of the Earth’s magnetic field. Earlier this year they confirmed the ability of salmon to navigate using the magnetic field in experiments at the Oregon Hatchery Research Center. Scientists for decades have studied how salmon find their way across vast stretches of ocean.

“The better fish navigate, the higher their survival rate,” said Putman, who conducted the research at the Oregon Hatchery Research Center in the Alsea River basin last year. “When their magnetic field is altered, the fish get confused.”

Subtle differences in the magnetic environment within hatcheries could help explain why some hatchery fish do better than others when they are released into the wild, Putman said. Stabilizing the magnetic field by using alternative forms of hatchery construction may be one way to produce a better yield of fish, he said.

“It’s not a hopeless problem,” he said. “You can fix these kinds of things. Retrofitting hatcheries with non-magnetic materials might be worth doing if it leads to making better fish.”

Putman’s findings were published this week in the journal Biology Letters. The research was funded by Oregon Sea Grant and the Oregon Department of Fish and Wildlife, with support from Oregon State University. Co-authors of the study are OSU’s David Noakes, senior scientist at the Oregon Hatchery Research Center, and Amanda Meinke of the Oregon Hatchery Research Center.

The new findings follow earlier research by Putman and others that confirmed the connection between salmon and the Earth’s magnetic field. Researchers exposed hundreds of juvenile Chinook salmon to different magnetic fields that exist at the latitudinal extremes of their oceanic range.

Fish responded to these “simulated magnetic displacements” by swimming in the direction that would bring them toward the center of their marine feeding grounds. In essence, the research confirmed that fish possess a map sense, determining where they are and which way to swim based on the magnetic fields they encounter.

Putman repeated that experiment with the steelhead trout and achieved similar results. He then expanded the research to determine if changes to the magnetic field in which fish were reared would affect their map sense. One group of fish was maintained in a fiberglass tank, while the other group was raised in a similar tank but in the vicinity of iron pipes and a concrete floor with steel rebar, which produced a sharp gradient of magnetic field intensity within the tank. Iron pipes and steel reinforced concrete are common in fish hatcheries.

The scientists monitored and photographed the juvenile steelhead, called parr, and tracked the direction in which they were swimming during simulated magnetic displacement experiments. The steelhead reared in a natural magnetic field adjusted their map sense and tended to swim in the same direction. But fish that were exposed to the iron pipes and steel-reinforced concrete failed to show the appropriate orientation and swam in random directions.

More research is needed to determine exactly what that means for the fish. The loss of their map sense could be temporary and they could recalibrate their magnetic sense after a period of time, Putman said. Alternatively, if there is a critical window in which the steelhead’s map sense is imprinted, and it is exposed to an altered magnetic field then, the fish could remain confused forever, he said.

“There is evidence in other animals, especially in birds, that either is possible,” said Putman, who now works for the National Oceanic and Atmospheric Administration. “We don’t know enough about fish yet to know which is which. We should be able to figure that out with some simple experiments.”

Reflections on wilderness featured at Corvallis Science Pub

CORVALLIS, Ore. – Fifty years ago, Congress passed the Wilderness Act, which today protects nearly 110 million acres in the United States. At the June 9 Corvallis Science Pub, Cristina Eisenberg, an Oregon State University conservation biologist, will discuss why intact wilderness areas matter more today than they did in 1964.

The Science Pub presentation is free and open to the public and begins at 6 p.m. in the Majestic Theater, 115 S.W. Second St. in Corvallis.

Eisenberg’s intimate acquaintance with wilderness stems from 20 years of living with her family in a cabin adjacent to the Bob Marshall Wilderness in Montana. At 1 million acres, it comprises the second-largest wilderness area in the lower 48 states.

In her research, she studies interactions among wolves, elk, aspen and fire. In Rocky Mountain ecosystems, she has shown that relatively intact, large tracts of land are essential to create ecologically resilient landscapes. Such landscapes typically consist of extensive protected wilderness.

She will also read and show images from her recently published book, The Carnivore Way, in which she profiles the Crown of the Continent ecosystem, a 28-million-acre wildlife corridor that runs along the mountainous spine of North America.

Sponsors of Science Pub include Terra magazine at OSU, the Downtown Corvallis Association and the Oregon Museum of Science and Industry.

Businesses need to plan for, address impacts on biodiversity, new report indicates

CORVALLIS, Ore. – Businesses large and small need to begin the difficult work of assessing and addressing their impact on biodiversity and ecosystem services in order to reduce risk to natural resources in the future, according to a new report from Oregon State University researchers.

Biodiversity and ecosystem services refer to the variety and diversity of plants and animals in the ecosystem and the benefits that nature provides, respectively. They should be part of companies’ strategic planning, said Sally Duncan, director of the OSU Policy Analysis Lab in the School of Public Policy.

“This is an issue of risk management – it has to be part of a strategic plan,” Duncan said. “As one pioneer company leader put it, the greatest risk of all is not doing anything.”

The report, “The New Nature of Business: How Business Pioneers Support Biodiversity and Ecosystems Services,” provides a framework for companies to begin identifying and addressing their potential impacts on the ecosystem.

The report was published this month and is available at www.newnatureofbusiness.org. Partners in the multidisciplinary, international project include Oregon State University and the University of Sydney Business School. Funding comes from the National Science Foundation’s National Socio-Environmental Synthesis Center, with additional support from the University of Sydney Business School.

Biodiversity of plants, animals and microorganisms is essential to a properly functioning ecosystem. Ecosystem services are the benefits of such a system, and include goods such as food and fiber or services such as flood control or pest management.

But biodiversity is threatened by environmental degradation due to things such as habitat destruction and climate change. That, in turn, poses challenges for business leaders, who will have to deal with the ramifications, including pressure from consumers to improve business practices.

“There are many, many companies that have started doing important work on water conservation and energy conservation,” Duncan said. “Biodiversity and ecosystem services are much more complicated. They’re very hard to measure and most companies haven’t even thought about it yet.”

Corporate giants Dow Chemical Co., Pfizer Inc. and Wal-Mart Stores Inc., and smaller organizations such as the Eugene Water and Electric Board, are among the pioneers who are taking steps to address their impacts on biodiversity. Their efforts are highlighted in the report.

Pfizer created a Wildlife Management Team and employees are working to restore and enhance the wildlife on the company’s 2,200-acre manufacturing site in Michigan. Eugene Water and Electric is working with landowners and local government to change land management practices, rather than build a new water treatment plant and charge higher rates.

Researchers developed a decision-making framework to help other companies get started addressing their own impacts on biodiversity and ecosystems services. The hope is that business leaders will use and test the framework and share their experiences on the project website, Duncan said.

“Any change to a big organization is extremely difficult,” Duncan said. “If business leaders see a story on the website that they can relate to, it might seem less scary.”

Developing a tool to measure companies’ impacts on biodiversity and ecosystems services and making that tool available to companies around the world are some of the next steps for the project, she said.

Study: Targeted funding can help address inequities in early child care programs

CORVALLIS, Ore. – The quality of early child care and education programs is influenced both by funding and by the characteristics of the communities in which the programs operate, new research from Oregon State University shows.

The findings indicate that law- and policy-makers may need to consider the demographics of communities when making funding decisions about early childhood programs, said Bridget Hatfield, an assistant professor in OSU’s College of Public Health and Human Sciences.

That’s especially important now because many states, including Oregon, are adopting or revising quality ratings systems that tie funding to program quality, Hatfield said.

Her findings were published recently in “Early Childhood Research Quarterly.” Co-authors were Joanna K. Lower of Lower & Company, Deborah J. Cassidy of the University of North Carolina at Greensboro and Richard A. Faldowski of the University of North Carolina at Chapel Hill. Lower received funding for the research from the Office of Planning, Research and Evaluation, Administration for Children and Families, U.S. Department of Health and Human Services. Hatfield received funding for the research from the Institute of Education Sciences at the University of Virginia.

Hatfield studied about 7,000 licensed early child care and education programs in North Carolina, which has one of the nation’s oldest quality rating and improvement systems for early child care and education programs. These systems are used by many states to determine how much government funding an early child care and education program receives.

Oregon and many other states are in the midst of implementing a quality rating system.

Hatfield found that children from low-income communities have less access to high-quality early child care and preschool, even though they are likely to gain more benefits from it.

“There are a lot of barriers to high-quality education in disadvantaged communities,” she said. “Hiring teachers with bachelor’s degrees, providing appropriate school supplies and play equipment – you need money to do all those things.”

Her research also showed that additional government funding can provide a significant boost to the quality of programs in disadvantaged communities. Those programs make bigger quality improvements when they receive extra funding than programs that are in more affluent communities, Hatfield found.

“Just because a program is in a disadvantaged community doesn’t mean it can’t attain high quality,” she said. “The extra money helps the programs in disadvantaged communities close the gap.”

Hatfield studied family child care homes, where child care is provided in a private home, as well as child care centers and preschool programs, including federal programs such as Head Start.

The research shows that quality of child care can vary based on funding, but other factors also affect program quality, Hatfield said. For example, in other research projects, she is studying the interactions between teachers and children in the classroom. That kind of research will help child care program leaders determine how best to spend money they receive to improve their programs.

“If we give people more money, what’s the best way to spend it?” she said. “Do we buy more puzzles for the children or train the teachers to better use the puzzles they have?”

Corvallis Science Pub focuses on the future of the oceans

CORVALLIS, Ore. – Warming ocean temperatures, rising acidity and reduced biological productivity threaten the livelihoods of about 2 billion people who depend on marine ecosystems, according to a report by an international team of 29 scientists last fall.

At the May 12 Corvallis Science Pub, Andrew Thurber, a post-doctoral researcher at Oregon State University who helped to conceive the study, will discuss how the oceans are responding to a changing climate. The Science Pub presentation, which is free and open to the public, begins at 6 p.m. in the Majestic Theater located at 115 S.W. Second St. in Corvallis.

“What is really sobering about these findings is that they don’t even include other impacts to the world’s oceans such as sea level rise, pollution, over-fishing, and increasing storm intensity and frequency,” he said. “All of these could compound the problem significantly.”

Thurber’s research focuses on deep-sea ecosystems, particularly the role of invertebrates in recycling nutrients and sequestering carbon. He has conducted experiments under seasonal sea ice in Antarctica and explored communities that live around methane seeps near New Zealand and Costa Rica.

Thurber received his Ph.D. from the Scripps Institution of Oceanography, UC San Diego. His work has been supported by the National Science Foundation.

Sponsors of Science Pub include Terra magazine at OSU, the Downtown Corvallis Association and the Oregon Museum of Science and Industry.

“The Carnivore Way” could be key to large predator conservation

CORVALLIS, Ore. – North America’s mountainous backbone, stretching from Mexico to Alaska, could serve as a model for balancing the needs of large predators and people, an Oregon State University biologist suggests in a new book.

In “The Carnivore Way: Coexisting with and Conserving North America’s Predators,” published May 1 by Island Press, Cristina Eisenberg describes the ongoing efforts of humans to coexist with wolves, cougars, wolverines and other species in a largely wild but developing landscape.

Eisenberg, who grew up in a hunting and ranching family in northern Mexico, is an instructor in the Oregon State College of Forestry, a Smithsonian research associate and an Earthwatch scientist. She obtained her doctorate and completed two post-doctoral fellowships at Oregon State.

From her home in northwestern Montana, where grizzlies and wolves outnumber people, she traveled more than 13,000 miles – from the Arctic to northern Mexico – to trace corridors that link carnivores with the habitats they need to thrive. She met with scientists who studied these animals and with officials who found ways to conserve grizzlies, wolves, wolverines and other species. She talked with conservationists who hiked the trails and documented challenges to predators and their prey.

“Large carnivore conservation is ultimately about people,” Eisenberg wrote. “Science and environmental law can help us learn to share landscapes with fierce creatures, but ultimately coexistence has to do with our human hearts.”

For Eisenberg, it also has much to do with ecosystems. Wildlife scientists have documented the crucial role that large carnivores play in shaping forests and rangelands, she said.

“When you’re out there on the ground and a wolf shows up or a cougar shows up and starts doing what they do, you have these ‘aha’ moments,” Eisenberg said. “What I’m doing in ‘The Carnivore Way’ is providing a lot of stories and examples. There’s a massive amount of science in the book, but in the end, it’s sharing those ‘aha’ moments that help people connect with these animals.”

In a world in which ecosystems are reeling from climate change and other human influences, she said, wolves and other carnivores can restore resilience that benefits the resources that people depend on. By maintaining a role for carnivores, ecosystems are more likely to rebound in the face of drought, fire and other disturbances linked to a changing climate.

"Scientists studying ecosystems worldwide have found that carnivores indirectly improve the health and vigor of plant communities by reducing the density of their prey and in some cases by changing prey behavior,” said Eisenberg. “In many places in North America, for example, by preying on elk, wolves reduce the browsing pressure that elk place on plants. This enables trees and shrubs to grow to maturity and provide habitat for many other species, such as songbirds.”

Eisenberg’s research on the effects of predators on ecosystems has been supported by Parks Canada and the High Lonesome Ranch, which occupies 400 square miles in western Colorado. She and Oregon State co-investigator David Hibbs recently obtained Earthwatch Institute funding that will support their research on wolves, elk, and fire for several years. Articles featuring her research have appeared in National Geographic, The New York Times, High Country News and other outlets.

In 2010, Island Press published her previous book, “The Wolf’s Tooth,” which describes the ecological roles of large carnivores. She is writing a book on climate change, “Taking the Heat: Wildlife, Food Webs, and Extinction in a Warming World,” also for Island Press.

Changes in processing, handling could reduce commercial fishing injuries, research shows

CORVALLIS, Ore. – Handling frozen fish caused nearly half of all injuries aboard commercial freezer-trawlers and about a quarter of the injuries on freezer-longliner vessels operating off the coast of Alaska, new research from Oregon State University shows.

Many of those injuries and others aboard the two types of vessels could be prevented with the right interventions, and the research methods used in the study could help identify and reduce injuries and fatalities in other types of commercial fishing, said researcher Devin Lucas. His findings were published in the “American Journal of Industrial Medicine.”

“We’ve drilled down to such a detailed level in the injury data that we can actually address specific hazards and develop prevention strategies,” said Lucas, who recently received his Ph.D. in public health from OSU’s College of Public Health and Human Sciences and works for the National Institute for Occupational Safety and Health (NIOSH) in the Alaska Pacific office.  

Lucas’ study is the first scientific assessment of the risk of fishing on freezer-trawlers and freezer-longliners. In both types of vessels, the processing of fish is handled on-board. The vessels had reputations for being among the most dangerous in commercial fishing in part because of a few incidents that resulted in multiple fatalities.

However, an analysis of 12 years of injury data showed that fishing on the freezer vessels was less risky than many other types of commercial fishing, which is one of the most dangerous occupations in the United States, Lucas said. The rate of injury on freezer-trawlers was about the same as the national average for commercial fishing, while the rate aboard freezer-longliners was about half of the national average.

“The reality is that many fisheries elsewhere in the U.S., including Oregon Dungeness crabbing, are much more dangerous,” Lucas said.

His review of injury data indicated that the majority of injuries in the freezer-trawler fleet occurred in the factories and freezer holds, while the most common injuries in the freezer-longliner fleet occurred on deck while working the fishing gear. Injuries from processing and handling fish were also common on the longliners, the research showed.

Study co-author Laurel Kincl, an assistant professor of environmental and occupational health and safety in the College of Public Health and Human Sciences, said the methods used in the research, including describing and categorizing the types of injuries, can now be applied to other commercial fishing industries to identify safety issues and pinpoint areas for prevention.

“Not all commercial fishing is the same,” Kincl said. “You have different equipment, different processes.”

Kincl said researchers are hoping to build from this research and explore other fishing-related injuries and prevention strategies. The Dungeness crab industry is one area that may be explored and another is land-based fish-processing, she said.

Additional authors of the study were Viktor E. Bovbjerg and Adam J. Branscum, associate professors in the College of Public Health and Human Sciences at OSU and Jennifer M. Lincoln of NIOSH. The research was supported by OSU and NIOSH.
