James “Jim” Patterson, city manager and CEO of the City of Corvallis, has been named the OSU Foundation's new lead fundraiser for OSU athletics.
CORVALLIS, Ore. – James “Jim” Patterson, city manager and CEO of the City of Corvallis, has been named the Oregon State University Foundation's new senior associate athletics director/senior director of development for intercollegiate athletics.
Patterson brings to the foundation 12 years of experience in the public sector as well as 20 years of experience in private sector sales, executive sales management, marketing and promotions. In addition to providing leadership to the OSU Foundation athletics development staff and Our Beaver Nation, he will oversee fundraising communications, donor relations and the annual fund for OSU athletics, all of which support Beaver student-athletes.
The unit recently surpassed its $180 million fundraising goal as part of The Campaign for OSU and has begun planning for its next major initiatives. In his new role, Patterson will report directly to Mike Goodwin, president and CEO of the OSU Foundation.
As city manager and CEO of the City of Corvallis, Patterson led the strategic rebuilding of the city’s general fund reserves to more than $5 million; successfully negotiated union contracts projected to save the city millions of dollars in the future by moving employees to more affordable health care plans; and spearheaded the creation of a city budget development process that requires firm expenditure limits and revenues that equal expenditures.
Patterson is no stranger to the Oregon State community. As city manager, he worked as a partner and collaborator with various OSU entities, including the president’s office and board of trustees, to strengthen and enhance the relationship between the city and the university community. He is the public address announcer for OSU women’s basketball, an OSU parent and longtime supporter of Beaver athletics.
“I am proud to be joining two great organizations whose partnership has meant so much to OSU,” said Patterson. “The campaign has demonstrated the significant impact generous donors can have. I know that Oregon State University aspires to continue to improve the educational experience for all students and I look forward to being a part of that effort.”
The candidates who came forward for this position “made it a very competitive field,” according to OSU Foundation President and CEO Goodwin.
“Jim’s skills and knowledge stood out in what was a highly competitive national search,” Goodwin said. “He brings a wealth of critical experience to this role with the foundation, as well as a great deal of enthusiasm and relationship-building skills that will rally support for Beaver athletics.”
Prior to serving as the Corvallis city manager and CEO, Patterson served in the same capacity for the City of Sherwood, Oregon, from 2004–11. His time in the private sector included positions with United Advertising Media, United and Allied Van Lines, and OWNCO Marketing in Portland. He earned a bachelor’s degree from Portland State University.
Patterson will begin his work at the OSU Foundation on Aug. 25.OSU Foundation Source:

An OSU workshop on Aug. 23-24 called ChickTech is designed to encourage high school girls to enter computer and technical fields.
CORVALLIS, Ore. – ChickTech is hosting a workshop on Aug. 23-24 at Oregon State University to encourage high school girls to enter computing and technical fields.
The event culminates with a show on Sunday, Aug. 24, that’s free and open to the public. It will be from 4:30-5:45 p.m. at the Kelley Engineering Center on the OSU campus, and participants will display the projects they built.
The students may help create a robot, build a video game, or make a smartphone application, and are mentored by industry and academic professionals from high-tech fields. The event is free for participants, and includes an overnight stay in an OSU residence hall. It’s sponsored or supported by the OSU School of Electrical Engineering and Computer Science, the Women and Minorities program, the OSU Library, Tektronix, HP, Kattare, and Korvis.
The event is designed as a fun, positive learning experience to build participants’ confidence in their technical abilities, provide positive role models, and create connections with other young women from the area.
ChickTech is a non-profit organization, founded in Portland in 2013 by OSU alumna, Janice Levenhagen-Seeley, who was motivated by her own experiences to foster a more inviting culture for women.
“It was hard to feel like I belonged as a woman in computer engineering,” Levenhagen-Seeley said. “So I started ChickTech to give other girls and women the support that I didn’t have. I want them to feel like they are welcome and have unique things that they are bringing to the industry.”College of Engineering Media Contact:

OSU is joining a new national movement to create "badges" that recognize learning, and offer an online credential of education and knowledge.
CORVALLIS, Ore. – The Professional and Continuing Education, or PACE program at Oregon State University has begun an educational “badge” initiative, becoming part of an innovative national movement to expand the way learning accomplishments can be recognized.
These digital badges offer an additional method to recognize skills, education and abilities. As an “open credential,” they are detailed and personalized – and via computers can offer a more current and exact description of just what a person knows how to do.
The movement is conceptually similar to the “merit badges” that scouts have used for decades. But instead of a canoeing badge sewn onto a sash that verifies a person knows how to paddle a canoe, digital badges are computer icons that both recognize and can link to a full description of a person’s knowledge in a particular field – anything from robotics to welding to financial management.
At OSU, the first 300 badges have been issued to graduates of the popular “master gardener” online program. About 700 more badges are going to be presented to graduates of four other PACE programs in coming months.
“With employers relying more heavily on social media platforms like LinkedIn to make salary and career advancement decisions, we wanted to provide our students with a form of web-based credentialing that is secure, portable and meets contemporary workforce-related needs,” said Chris LaBelle, director of Professional and Continuing Education.
At OSU, LaBelle said, badges may be used to signify completion of a certificate program, an intensive workshop or the acquisition of a certain set of skills. They will be offered as a supplement to traditional degrees and certifications.
The badge movement is still in its infancy, but is already being embraced by a variety of institutions, from universities to private industry, government agencies and trade organizations. Open source computer software companies are among its advocates, and the system being used at OSU will work on multiple digital platforms.
In this initiative, OSU is working with the Oregon Badge Alliance, a non-profit organization working to set up a system of badges and micro-certifications in the state. Badges can provide detail on skills and achievements that aren’t available on traditional academic records and may include a range of work and studies far beyond a person’s academic degree. Creators of a badge clearly spell out the criteria for earning them, and they can recognize a specific accomplishment or sometimes continued growth in a general area of study.
“Because open badges can be collected from multiple sources, the possibilities are really endless,” said Wayne Skipper, founder of the Oregon Badge Alliance Wayne Skipper said. “In a rapidly evolving education landscape, the ability for students to quantify their own learning achievements is paramount. That requires more granular data than what we normally see on a transcript.”
PACE’s digital badge program has attracted the attention of other OSU colleges and departments as well, LaBelle said.
“Digital badges have the potential to become a university-wide program,” LaBelle said. “While non-degree students will receive the first wave of digital badges issued by our unit, I fully expect a demand for this form of micro-credentialing to spill over to OSU's student services and degree-based programs.”
Digital badges are already a national movement.
One university, for instance, provides different badges for various milestones in robotics, and another provides badges for reaching benchmarks of learning in regular, credit-bearing college courses.
Once awarded, badges can also be linked to a wide range of information that would never be found on an academic transcript, such as workshops attended, awards won, projects completed, essays written or work samples.
Colleges like OSU, the University of California and Carnegie Mellon are being joined by many other institutions in the badge movement. The Smithsonian Institution is awarding badges, as are the National Oceanic and Atmospheric Administration, National Association of Manufacturers, Intel and Disney-Pixar.Outreach and Engagement Media Contact:

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.
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.”College of Liberal Arts Media Contact: Michelle Klampe Source:

Three OSU faculty members have been named 2014 fellows of the American Geophysical Union. They are the only three fellows in this class from the state of Oregon.
CORVALLIS, Ore. – Three Oregon State University faculty members have been named 2014 fellows of the American Geophysical Union. They are the only three fellows in this class from the state of Oregon.
The three selected as fellows were Edward Brook and Gary Egbert from the College of Earth, Ocean, and Atmospheric Sciences; and Beverly Law from the College of Forestry.
Brook is a paleoclimatologist who studies the Earth’s ancient climates through examination of ice cores, specializing in the history of greenhouse gases. His studies have helped explain the processes that led to large-scale climate shifts throughout Earth’s history. In 2011, he was part of a team that completed the excavation of a 10,928-foot ice core – the longest core ever drilled by United States scientists – with ice more than 67,000 years old.
Egbert is a geophysicist and oceanographer whose studies range from ocean tides to electromagnetic imaging of the solid Earth. In one pioneering study, he and his colleagues used satellite altimetry data to show that ocean tides lose significant energy over rough topography in the open ocean. These results imply that the tides may provide an important source of mechanical energy for vertical ocean mixing, and large-scale heat transport in the ocean – processes which are critical to Earth’s climate.
Law is a professor of global change biology and terrestrial systems science who examines the role of forests in the global carbon cycle, and the impacts of climate change on those forests. She was science chair of the AmeriFlux network of more than 100 research sites for 11 years, and in 2014 was listed as a “most highly cited” researcher, in the top 1 percent for the period of 2002-12. She is a principal investigator on a five-year, $4 million project studying the impacts of drought, insects and fires on western forests.
The American Geophysical Union established the AGU Fellows program in 1962, and restricts annual recognition to less than 0.1 percent of its overall membership. This year, 62 fellows were named for their scientific eminence, a major breakthrough, a major discovery, paradigm shifts and/or sustained scientific impact. They will be recognized on Dec. 17 at the annual AGU conference in San Francisco.Generic OSU Media Contact: Mark Floyd Source:

The world’s oceans are vast and deep, yet technology and the quest for extracting resources from previously unreachable depths is beginning to put the deep seas on the cusp of peril.
CORVALLIS, Ore. – The world’s oceans are vast and deep, yet rapidly advancing technology and the quest for extracting resources from previously unreachable depths is beginning to put the deep seas on the cusp of peril, an international team of scientists warned this week.
In an analysis in Biogeosciences, which is published by the European Geosciences Union, the researchers outline “services” or benefits provided by the deep ocean to society. Yet using these services, now and in the future, is likely to make a significant impact on that habitat and what it ultimately does for society, they point out in their analysis.
“The deep sea is the largest habitat on Earth, it is incredibly important to humans and it is facing a variety of stressors from increased human exploitation to impacts from climate change,” said Andrew Thurber, an Oregon State University marine scientist and lead author on the study. “As we embark upon greater exploitation of this vast environment and start thinking about conserving its resources, it is imperative to know what this habitat already does for us.”
“Our analysis is an effort to begin to summarize what the deep sea provides to humans because we take it for granted or simply do not know that the deep sea does anything to shape our daily lives,” he added. “The truth is that the deep sea affects us, whether we live on the coast or far from the ocean – and its impact on the globe is pervasive.”
The deep sea is important to many critical processes that affect the Earth’s climate, including acting as a “sink” for greenhouse gases – helping offset the growing amounts of carbon dioxide emitted into the atmosphere. It also regenerates nutrients through upwelling that fuel the marine food web in productive coastal systems such as the Pacific Northwest of the United States, Chile and others. Increasingly, fishing and mining industries are going deeper and deeper into the oceans to extract natural resources.
“One concern is that many of these areas are in international waters and outside of any national jurisdiction,” noted Thurber, an assistant professor (senior research) in Oregon State’s College of Earth, Ocean, and Atmospheric Sciences. “Yet the impacts are global, so we need a global effort to begin protecting and managing these key, albeit vast, habitats.”
Fishing is an obvious concern, the scientists say. Advances in technology have enabled commercial fisheries to harvest fish at increasing depths – an average of 62.5 meters deeper every decade, according to fisheries scientists. This raises a variety of potential issues.
“The ability to fish deeper is shifting some fisheries to deeper stocks, and opening up harvests of new species,” Thurber said. “In some local cases, individual fisheries are managed aggressively, but due to how slow the majority of the fish grow in the deep, some fish populations are still in decline – even with the best management practices.”
The orange roughy off New Zealand, for instance, is both a model of effective and conservation-based management, yet its populations continue to decline, though at a slower rate than they would have experienced without careful management, Thurber noted.
“We also have to be concerned about pollution that makes its way from our continental shelves into the deep sea,” he added. “Before it was ‘out of sight, out of mind.’ However, some of the pollution can either make it into the fish that we harvest, or harm the fishers that collect the fish for us. It is one of the reasons need to identify how uses of the deep sea in the short term can have long-term consequences. Few things happen fast down there.”
Mining is a major threat to the deep sea, the researchers point out in their analysis. In particular, the quest for rare earth and metal resources, which began decades ago, has skyrocketed in recent years because of their increased use in electronics, and because of dwindling or limited distribution of supplies on land. Mining the deep ocean for manganese nodules, for example – which are rich in nickel – requires machines that may directly impact large swaths of the seafloor and send up a sediment plume that could potentially affect an even larger area, the scientists note.
These mining resources are not limited to muddy habitats, Thurber pointed out. Massive sulfides present at hydrothermal vents are another resource targeted by mining interests.
“The deep sea has been an active area for oil and gas harvesting for many years,” he said, “yet large reservoirs of methane and other potential energy sources remain unexploited. In addition to new energy sources, the potential for novel pharmaceuticals is also vast.
“There are additional threats to these unique habitats, including ocean acidification, warming temperatures and possible changes to ocean circulation through climate change.”
The next step, the researchers say, is to attach an economic value to both the services provided by the deep sea – and the activities that may threaten those services.
“What became clear as we put together this synopsis is that there is vast potential for future resources but we already benefit greatly through this environment,” Thurber said. “”What this means is that while the choices to harvest or mine will be decided over the coming decades, it is important to note that the stakeholders of this environment represent the entire world’s population.”
“The Bible, the Koran, the Torah, and early Greek texts all reference the deep sea,” he added. “Maybe it’s time for all of us to take a closer look at what it has to offer and decide if and how we protect it.”College of Earth, Ocean, and Atmospheric Sciences Media Contact: Mark Floyd Source:

Oral birth control may not work as well in obese women, but Oregon researchers have found new strategies to help address that concern.
PORTLAND, Ore. – The findings of a new study suggest two ways to effectively address the problem that birth control pills may not work as well in obese women, compared to women of a normal body mass index.
Birth control pills are a one-size-fits-all method, researchers say, but as the population has increased in weight, concern has grown about how well the pill works for obese women. Studies have consistently found that obesity has a negative impact on drug levels in the body, which may in turn affect how well the pill prevents pregnancy.
“Birth control pills have been shown in a large population study to fail at a higher rate in women who are obese,” said Ganesh Cherala, an assistant professor in the Oregon State University/Oregon Health & Science University College of Pharmacy.
“Our original studies were focused on why this might occur,” Cherala said, “and we found that obesity changes how a woman’s body clears contraceptive hormones.”
It takes longer for the pill to reach a steady state level in obese women, with possible impacts on efficacy of the birth control, and putting them at greater risk for a pill failure if they forget to take a pill or take it later.
In order to offset these changes, Cherala and Dr. Alison Edelman, an associate professor of obstetrics and gynecology at Oregon Health & Science University, studied two alternative strategies. They found that either a slight increase in the pill dose, from a very low dose to a low dose pill; or using the pill continuously without a “period week” off, appeared to counteract the changes that obesity causes.
This, in turn, may provide improved pregnancy prevention for women of differing weights who use the pill, the researchers said. Their work is published in Contraception, a professional journal, and was supported by the National Institutes of Health.
“Since oral contraception remains one of the most popular forms of birth control in the United States and the majority of our population is obese or overweight, it’s important to find methods of contraception that work for all women, no matter what their weight,” Edelman said.
“The strategies that we studied can be, and are currently being used by women, but now we know that they help to counteract the adverse effects of weight on contraceptive hormones,” she said.
For obese women, simply shifting to an alternative form of birth control is an option, the researchers said. But they also pointed out that oral contraceptives are the most preferred form of birth control and that a woman’s individual preference influences her adherence and continuation with any method.College of Pharmacy Media Contact: David Stauth Source:

The first four companies working with the OSU Advantage Accelerator have completed the program and are moving toward commercial success.
CORVALLIS, Ore. – Four promising startup companies in fields ranging from social media to chemical manufacturing are among the first “graduating class” of the Oregon State University Advantage Accelerator, upon completion of a program designed to help lead them toward commercial success.
Organizers of the new program say it’s off to a promising start in efforts to bring more university research and community ideas to the commercial marketplace. This and other elements of the OSU Advantage form partnerships with industry and work to boost the Oregon economy, while providing invaluable experiences for OSU students involved in many aspects of the program.
“Our program has unfolded as well or better than we had hoped, and we now plan to increase the output,” said John Turner, co-director of the Advantage Accelerator. “Completion of this program means that companies have an increased chance to succeed and have a step-by-step plan to approach the future.”
“Based on our experience in the first year of this program, we’ve decided to conduct two cohort groups each year rather than one,” Turner said. “The coming year will result in about 15-20 new startup companies.”
Success in a tough and competitive commercial marketplace is not automatic, however, and not all companies have the will and strength to complete the rigorous program.
The first graduates have completed a “portfolio” of accomplishments, Turner said, that included training to attract investors, a validated business model, a schedule for future steps, and an initial product to show prospective customers, investors or manufacturers. A few clients are already attracting attention through the sale of products and generating profit.
The OSU Advantage Accelerator provides mentoring with industry and entrepreneurial experts, consulting sessions, access to seed grants and the OSU Venture Fund, meetings with active investors, workshops on various topics, networking events and many other activities.
One of the early participants in the program, Onboard Dynamics of Bend, Ore., plans to market technology that could ultimately revolutionize the way America drives. It has developed systems that compress natural gas right in the vehicle and take advantage of the enormous current supplies of low-cost natural gas. The innovation is able to cut automobile fuel costs to the gasoline-equivalent of less than $1 a gallon.
“An intern working with the Advantage Accelerator performed a lot of tasks relating to market analysis and startup activities that were incredibly helpful to the company,” said CEO Rita Hansen.
“We’re in an excellent position right now, having been formally selected by the Department of Energy for a $2.88 million award, and our initial target markets are the underserved, small, light-duty commercial fleets,” Hansen said. “We’re very bullish about widespread adoption by these fleets of our products.”
A few other companies that have completed the program include:
- Pikli, a student-based company based on social media that allows individuals to involve their friends and family in their shopping experiences;
- Waste2Watergy, which is commercializing a microbial fuel cell technology to reduce or eliminate significant wastewater costs and produce electricity from the resultant effluence; and
- Valliscor, a chemical manufacturing company that licensed technology developed at OSU to produce high-value chemicals for the pharmaceutical, agricultural, polymer and electronics industries.
“The OSU Advantage Accelerator program was very helpful and their mentorship was really first-rate,” said Rich Carter, professor and chair of the OSU Department of Chemistry, and CEO of Valliscor. “They helped us develop the necessary tools to become a functioning company, and whenever you needed advice all you had to do was pick up the phone.”
Carter said he’s “very optimistic” about the company going forward, which is already producing and selling its first products.
The OSU Advantage Accelerator is one component of the Oregon Regional Accelerator and Innovation Network, or Oregon RAIN. With support from the Oregon legislature, collaborators on the initiative include OSU, the University of Oregon, the cities of Eugene, Springfield, Corvallis and Albany, and other economic development organizations. All the participants are focused on creating new business, expanding existing business, creating jobs and helping to build the Oregon and national economy.Oregon State University Advantage Media Contact: David Stauth Source:

A study by OSU researchers suggests that synchronization of climate patterns in the North Pacific and North Atlantic oceans may be the early warning sign for a climate change "tipping point."
CORVALLIS, Ore. – Scientists have long been concerned that global warming may push Earth’s climate system across a “tipping point,” where rapid melting of ice and further warming may become irreversible – a hotly debated scenario with an unclear picture of what this point of no return may look like.
A newly published study by researchers at Oregon State University probed the geologic past to understand mechanisms of abrupt climate change. The study pinpoints the emergence of synchronized climate variability in the North Pacific Ocean and the North Atlantic Ocean a few hundred years before the rapid warming that took place at the end of the last ice age about 15,000 years ago.
The study suggests that the combined warming of the two oceans may have provided the tipping point for abrupt warming and rapid melting of the northern ice sheets.
Results of the study, which was funded by the National Science Foundation, appear this week in Science.
This new discovery by OSU researchers resulted from an exhaustive 10-year examination of marine sediment cores recovered off southeast Alaska where geologic records of climate change provide an unusually detailed history of changing temperatures on a scale of decades to centuries over many thousands of years.
“Synchronization of two major ocean systems can amplify the transport of heat toward the polar regions and cause larger fluctuations in northern hemisphere climate,” said Summer Praetorius, a doctoral student in marine geology at Oregon State and lead author on the Science paper. “This is consistent with theoretical predictions of what happens when Earth’s climate reaches a tipping point.”
“That doesn’t necessarily mean that the same thing will happen in the future,” she pointed out, “but we cannot rule out that possibility.”
The study found that synchronization of the two regional systems began as climate was gradually warming. After synchronization, the researchers detected wild variability that amplified the changes and accelerated into an abrupt warming event of several degrees within a few decades.
“As the systems become synchronized, they organized and reinforced each other, eventually running away like screeching feedback from a microphone,” said Alan Mix, a professor in OSU’s College of Earth, Ocean, and Atmospheric Sciences and co-author on the paper. “Suddenly you had the combined effects of two major oceans forcing the climate instead of one at a time.”
“The example that we uncovered is a cause for concern because many people assume that climate change will be gradual and predictable,” Mix added. “But the study shows that there can be vast climate swings over a period of decades to centuries. If such a thing happened in the future, it could challenges society’s ability to cope.”
What made this study unusual is that the researchers had such a detailed look at the geologic record. While modern climate observations can be made every day, the length of instrumental records is relatively short – typically less than a century. In contrast, paleoclimatic records extend far into the past and give good context for modern changes, the researchers say. However, the resolution of most paleo records is low, limited to looking at changes that occur over thousands of years.
In this study, the researchers examined sediment cores taken from the Gulf of Alaska in 2004 during an expedition led by Mix. The mountains in the region are eroding so fast that sedimentation rates are “phenomenal,” he said. “Essentially, this rapid sedimentation provides a ‘climate tape recorder’ at extremely high fidelity.”
Praetorius then led an effort to look at past temperatures by slicing the sediment into decade-long chunks spanning more than 8,000 years – a laborious process that took years to complete. She measured ratios of oxygen isotopes trapped in fossil shells of marine plankton called foraminifera. The isotopes record the temperature and salinity of the water where the plankton lived.
When the foraminifera died, their shells sank to the sea floor and were preserved in the sediments that eventually were recovered by Mix’s coring team.
The researchers then compared their findings with data from the North Greenland Ice Core Project to see if the two distinct high-latitude climate systems were in any way related.
Most of the time, the two regions vary independently, but about 15,500 years ago, temperature changes started to line up and then both regions warmed abruptly by about five degrees (C) within just a few decades. Praetorius noted that much warmer ocean waters likely would have a profound effect on northern-hemisphere climates by melting sea ice, warming the atmosphere and destabilizing ice sheets over Canada and Europe.
A tipping point for climate change “may be crossed in an instant,” Mix noted, “but the actual response of the Earth’s system may play out over centuries or even thousands of years during a period of dynamic adjustment.”
“Understanding those dynamics requires that we look at examples from the past,” Mix said. “If we really do cross such a boundary in the future, we should probably take a long-term perspective and realize that change will become the new normal. It may be a wild ride.”
Added Praetorius: “Our study does suggest that the synchronization of the two major ocean systems is a potential early warning system to begin looking for the tipping point.”College of Earth, Ocean, and Atmospheric Sciences Media Contact: Mark Floyd Source:
A 15-year analysis of satellite-tagged blue whales off the West Coast found that their favored feeding areas are bisected by heavily used shipping lanes, increasing the threat of injury and mortality.
NEWPORT, Ore. – A comprehensive 15-year analysis of the movements of satellite-tagged blue whales off the West Coast of the United States found that their favored feeding areas are bisected by heavily used shipping lanes, increasing the threat of injury and mortality.
The researchers note that moving the shipping lanes off Los Angeles and San Francisco to slightly different areas – at least, during summer and fall when blue whales are most abundant – could significantly decrease the probability of ships striking the whales. A similar relocation of shipping lanes in the Bay of Fundy off eastern Canada lowered the likelihood of vessels striking endangered right whales an estimated 80 percent.
Results of the study – which was supported by the Office of Naval Research, the National Geographic Society, the National Science Foundation, private gifts to the Oregon State University Marine Mammal Institute and others – are being published this week in the journal PLOS ONE.
The analysis is the most comprehensive study of blue whales movements ever conducted. It was led by researchers at Oregon State University’s Marine Mammal Institute, who tracked the movement of blue whales off the West Coast to identify important habitat areas and environmental correlates, and subsequently to understand the timing of their presence near major ports and shipping traffic.
“The main areas that attract blue whales are highly productive, strong upwelling zones that produce large amounts of krill – which is pretty much all that they eat,” said Ladd Irvine, a researcher with OSU’s Marine Mammal Institute and lead author on the PLOS ONE study. “The whales have to maximize their food intake during the summer before they migrate south for the winter, typically starting in mid-October to mid-November.”
“It appears that two of their main foraging areas are coincidentally crossed by shipping lanes,” Irvine added.
In their study, the researchers attached transmitters to 171 blue whales off California at different times between 1993 and 2008 and tracked their movements via satellite. Their study looked at seasonal as well as individual differences in whale distribution, documenting a high degree of variability – but also a strong fidelity to the upwelling zones that coincide with ship traffic to and from the major ports of Los Angeles and San Francisco.
Blue whales can grow to the length of a basketball court, weigh as much as 25 large elephants combined, and their mouths could hold 100 people, though their diet is primarily krill – tiny shrimp-like creatures less than two inches in length. The blue whale is the largest creature to ever inhabit the Earth, yet little was known about their range or where they went to breed until Oregon State’s Bruce Mate led a series of tracking studies featured in the popular 2009 National Geographic documentary, “Kingdom of the Blue Whale.”
An estimated 2,500 of the world’s 10,000 blue whales spend time in the waters off the West Coast of the Americas and are known as the eastern North Pacific population. The huge whales can travel from the Gulf of Alaska all the way down to an area near the equator known as the Costa Rica Dome.
The majority of the population spends the summer and fall in the waters off the U.S. West Coast, with the areas most heavily used by the tagged whales occurring off California’s Santa Barbara and San Francisco, which puts them in constant peril from ship strikes.
“During one year, while we were filming the documentary, five blue whales were hit off of southern California during a seven-week period,” said Mate, who directs the Marine Mammal Institute at OSU’s Hatfield Marine Science Center in Newport, Ore. “Blue whales may not be as acoustically aware as species that rely on echolocation to find prey and there is some evidence that the location of the engines in the rear of the ship creates something of an acoustic shadow in front of them, making it hard for whales to hear the ship coming.
“Putting some kind of noise deterrent on the ships isn’t really an option, however,” Mate added. “You don’t really want to drive endangered whales out of their prime habitat and best feeding locations.”
Moving the shipping lanes would not be unprecedented, the researchers note. Scientists brought concerns about right whale ship strikes in the Bay of Fundy to the International Maritime Organization, and the industry led the effort to modify shipping lanes in the North Atlantic more than a decade ago.
Daniel Palacios, also a co-author on the paper and a principal investigator with OSU’s Marine Mammal Institute, said vessel traffic between Santa Barbara and Los Angeles moved south of its current location in the past to comply with the California Clear Air Act, but shifted back to its current location after getting an exemption to the legislation.
“It is not often that research results are so applicable to a policy decision.” Palacios said, “It’s not really our place to make management decisions, but we can inform policy-makers and in this case it is pretty straightforward. You will eliminate many of the ship strikes on blue whales by moving the shipping lanes south of the northern Channel Islands.”
The solution for the San Francisco area is similar, the researchers note, though not quite as simple. Three separate shipping lanes are used in the region and all cross through the home range and core areas of blue whales tagged in this study.
“We did find that the northernmost shipping lanes crossed the area that was most heavily used by tagged whales,” Irvine noted. “Restricting use of the northern lane during the summer and fall when more whales are present is one option; another would be to extend one lane further offshore before separating it into different trajectories, minimizing the overlap of the shipping lanes with the areas used by blue whales.”
The National Oceanic and Atmospheric Administration is planning a review of shipping lanes in the southern California area, which will be informed by this study. A variety of stakeholders must be consulted, however, before any changes are implemented.
Other funding sources for this study over the years including the TOPP Program (Tagging of Pacific Pelagics), the OSU Marine Mammal Institute Endowment, the Alfred P. Sloan Foundation, the Packard Foundation, NASA, the U.S. Geological Survey, the National Park Service, U.S. Fish and Wildlife Service and the Smithsonian Institution.Hatfield Marine Science Center Media Contact: Mark Floyd Source:

Kristin Watkins, associate vice president for advancement at Portland Community College and executive officer of the PCC Foundation, has been named the head of the OSU Foundation's office in Portland.
PORTLAND, Ore. – Kristin Watkins, associate vice president for advancement at Portland Community College and executive officer of the PCC Foundation, has been named the head of Oregon State University Foundation's office in Portland.
Watkins brings 17 years of experience in the Portland metro area to her new position as associate vice president of the OSU Portland Center. In addition to providing leadership to the OSU Foundation staff based in Portland, she will lead efforts to increase private support for OSU in the metropolitan area. With more than 40,000 alumni in greater Portland, the region is home to one in four of the university’s graduates.
As PCC’s chief advancement officer, Watkins established and led fundraising plans that nearly tripled annual revenue, bringing that institution’s fundraising program into the top 10 percent of community colleges in the nation.
“I couldn’t be more excited about joining the OSU Foundation’s team,” Watkins said. “As a graduate of two other land grant universities, I am passionate about the threefold land grant mission of accessible education, research and community outreach. It will be an honor to represent OSU in Portland and extend the university’s connections with alumni and other partners.”
The addition of Watkins to the OSU Foundation’s leadership team comes as the organization prepares to conclude Oregon State’s first comprehensive fundraising campaign on Dec. 31. In June, gifts from donors to The Campaign for OSU totaled more than $1.06 billion, including more than $180 million for scholarships and fellowships. Scholarship gifts like these support more than 3,000 students at OSU each year. Public events to celebrate the campaign’s donors are scheduled for Friday, Oct. 31.
To date Portland metro donors have contributed more than $330 million to the campaign.
“The campaign has been a tremendous launching point for us, and as we move forward it is even more important that we build our relationships in Portland; it’s our most important market,” said Mike Goodwin, president and CEO of the OSU Foundation. “Kristin is well-known in the community, and her leadership has created truly impressive results. We are thrilled to welcome her to the Oregon State family.”
Shawn Scoville, the OSU Foundation’s executive vice president, added, “Not only do we have a tremendous community of alumni and friends in Portland, we also are committed to supporting the city and our state by collaborating with a variety of nonprofits, industry partners, and colleagues in higher education, including PCC. Kristin is uniquely positioned to help us take these already strong relationships to the next level.”
A native of Virginia, Watkins graduated summa cum laude with a bachelor’s degree in international studies from Virginia Tech then earned a master’s degree in public affairs from the University of Minnesota. Prior to joining the Portland Community College staff, she was deputy director for Wider Opportunities for Women, a national nonprofit organization based in District of Columbia. She serves as a board member on District VIII for CASE – the Council for Advancement and Support of Education.
Watkins will begin her work at the OSU Portland Center in early September.

The OSU Board of Trustees on Friday approved the university’s operating budget for the 2014-15 fiscal year, and also approved new degree programs in robotics and religious studies.
CORVALLIS, Ore. – The Oregon State University Board of Trustees on Friday approved the university’s operating budget for the 2014-15 fiscal year, and also approved new master and doctoral degree programs in robotics and bachelor degree programs in religious studies.
This was the first meeting of the board after it officially took over oversight responsibility for the university on July 1 from the State Board of Higher Education. This change occurred as part of legislation adopted by the 2013 Oregon Legislature and the university’s decision to have its own independent board of directors appointed by the governor.
The board unanimously voted to adopt a $1.023 billion operating budget for the 2015 fiscal year, which covers OSU revenues and expenditures from July 1, 2014, through June 30, 2015. The revenue stream includes:
- Educational and program funding authorized by the state legislature;
- Projected tuition and fees paid by students;
- Auxiliary revenues from OSU service centers, including University Housing and Dining Services and OSU’s Department of Intercollegiate Athletics;
- External funds for teaching, research and outreach from private giving through the OSU Foundation, and from grants funded by state, federal or non-profit agencies or private industry.
The university’s budget for the 2013-14 fiscal year was $986.3 million.
The interdisciplinary robotics degree programs, which will begin in 2014-15, will be located within the School of Mechanical, Industrial and Manufacturing Engineering in OSU’s College of Engineering. During its first five years, the program is expected to graduate as many as 10 Ph.D. students and 30 master degree students and provide students expertise in the fields of robot design, control, manufacturing and operation that are rapidly growing worldwide. As many as 70 OSU students already are engaged in robotics studies.
The new bachelor of arts and bachelor of science degree programs in religious studies will be housed within OSU’s School of History, Philosophy and Religion in the College of Liberal Arts. The program will be initiated in fall 2015 and after five years would serve as many as 60 students. The decision restores religious study degree programs that were eliminated in the early 1990’s following budget cuts at Oregon State prompted by the adoption of state constitutional limits on property taxes.
The board also adopted a contract for the employment of OSU President Edward J. Ray through June 30, 2016, including terms of his compensation and his duties, responsibilities and annual performance evaluation.
The board also approved resolutions related to:
- How the university manages safeguards of U.S. Department of Defense classified information related to research contracts that may be awarded Oregon State;
- Reporting known or suspected fraud, waste and abuse within the university;
- Establishing a university code of ethics;
- Amending the charter of the OSU Board of Trustees’ executive and audit committee related to how external and internal university financial audits will be reviewed and approved by the board.
The board heard presentations from university finance and administration administrators related to public capital financing tools available for use by Oregon State; the university’s current and forecasted bonded indebtedness; and capital and facility improvement plans and procedures used by the university.Generic OSU Media Contact: Mark Floyd Source:

CORVALLIS, Ore. – As part of a NASA air and sea mission, Oregon State University researchers will measure ocean plants to see how changes in carbon levels could affect the future of fisheries and marine life.
Setting sail from Rhode Island on July 18, the Ship-Aircraft Bio-Optical Research (SABOR) campaign will use new optical instruments to pinpoint carbon levels in phytoplankton – tiny plants that play a critical role in carbon cycling. Phytoplankton absorb carbon dioxide during photosynthesis, distribute it when eaten by fish and other marine life, and then act as a carbon sink when they die and drift into the deep sea.
"Phytoplankton are the base of the marine food web and critical to the overall health of the Earth," said Mike Behrenfeld, one of the SABOR project scientists and a botany and plant pathology professor in OSU's College of Agricultural Sciences. “Changes to these microscopic plants – including the carbon they absorb – can affect an entire ocean, from sardine populations, to the location of native birds, and even to decreases in the survival of marine mammals.
"Understanding changes to phytoplankton biomass and photosynthesis are critical for projecting how oceans will fare in the future and how much of it is related to climate change," added Behrenfeld, who specializes in marine algae research.
The 20-day study has the team sailing and flying around the continental shelf off the East Coast of the United States. SABOR is unique among NASA projects because scientists will measure the ocean from both the air and water and try to find relationships between the two datasets. NASA will use the information to guide future satellite missions for understanding how the ocean and atmosphere are affected by climate.
The expedition will feature a state-of-the-art instrument that Behrenfeld's research team is using to separate phytoplankton from other particles in ocean water, such as bacteria, dead mass, and other types of plankton. The device, known as a sorting flow cytometer, uses a laser to detect phytoplankton in small streams of seawater. It then separates out the tiny plants to be analyzed for carbon. The technique is providing the first direct measurements of organic carbon in phytoplankton, said Behrenfeld.
While the Behrenfeld team is making measurements on the ship, an airplane will be collecting additional data, using an advanced laser system that can penetrate the ocean and measure phytoplankton levels in the upper depths of the water.
“By taking measurements using both the air and water instruments, scientists can gather a more accurate dataset than if they just used one or the other method," said Behrenfeld. "These relationships are the first step toward satellite technology that can provide an improved understanding of ocean ecology and its role in the carbon cycle.
"Eventually, new satellite missions will determine how and why ocean ecosystems are changing and the consequences to fish and the climate," Behrenfeld added.
The Behrenfeld research group is teaming with Kimberly Halsey, a microbiology professor with a joint appointment in OSU's College of Science and the College of Agricultural Sciences, to further understand how changes in phytoplankton numbers are related to their photosynthesis and general health. The two OSU teams include Allen Milligan, Jason Graff, Nerissa Fisher, and Matthew Brown.
SABOR is funded by the Ocean Biology and Biogeochemistry Program at NASA Headquarters, Washington. Project management and support will be provided by the Earth Science Project Office at NASA. Other mission scientists hail from the University of Maine; NASA's Langley Research Center; NASA's Goddard Institute for Space Studies; the City College of New York and others.Generic OSU Media Contact: Daniel Robison Source:

Lipoic acid may have such a wide range of biological effects because it helps to restore more normal circadian rhythms, which often decline with age.
CORVALLIS, Ore. – Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian rhythms, or the “biological clock” found in most life forms.
The ability of lipoic acid to help restore a more normal circadian rhythm to aging animals could explain its apparent value in so many important biological functions, ranging from stress resistance to cardiac function, hormonal balance, muscle performance, glucose metabolism and the aging process.
The findings were made by biochemists from the Linus Pauling Institute at Oregon State University, and published in Biochemical and Biophysical Research Communications, a professional journal. The research was supported by the National Institutes of Health, through the National Center for Complementary and Alternative Medicine.
Lipoic acid has been the focus in recent years of increasing research by scientists around the world, who continue to find previously unknown effects of this micronutrient. As an antioxidant and compound essential for aerobic metabolism, it’s found at higher levels in organ meats and leafy vegetables such as spinach and broccoli.
“This could be a breakthrough in our understanding of why lipoic acid is so important and how it functions,” said Tory Hagen, the Helen P. Rumbel Professor for Healthy Aging Research in the Linus Pauling Institute, and a professor of biochemistry and biophysics in the OSU College of Science.
“Circadian rhythms are day-night cycles that affect the daily ebb and flow of critical biological processes,” Hagen said. “The more we improve our understanding of them, the more we find them involved in so many aspects of life.”
Almost one-third of all genes are influenced by circadian rhythms, and when out of balance they can play roles in cancer, heart disease, inflammation, hormonal imbalance and many other areas, the OSU researchers said.
Of particular importance is the dysfunction of circadian rhythms with age.
“In old animals, including elderly humans, it’s well-known that circadian rhythms break down and certain enzymes don’t function as efficiently, or as well as they should,” said Dove Keith, a research associate in the Linus Pauling Institute and lead author on this study.
“This is very important, and probably deserves a great deal more study than it is getting,” Keith said. “If lipoic acid offers a way to help synchronize and restore circadian rhythms, it could be quite significant.”
In this case the scientists studied the “circadian clock” of the liver. Lipid metabolism by the liver is relevant to normal energy use, metabolism, and when dysfunctional can help contribute to the “metabolic syndrome” that puts millions of people at higher risk of heart disease, diabetes and cancer.
Researchers fed laboratory animals higher levels of lipoic acid than might be attained in a normal diet, while monitoring proteins known to be affected by disruption of the circadian clock in older animals.
They found that lipoic acid helped remediate some of the liver dysfunction that’s often common in old age, and significantly improved the function of their circadian rhythms.
In previous research, scientists found that the amount of lipoic acid that could aid liver and normal lipid function was the equivalent of about 600 milligrams daily for a 150-pound human, more than could normally be obtained through the diet.
A primary goal of research in the Linus Pauling Institute and the OSU Center for Healthy Aging Research is to promote what scientists call “healthspan” – not just the ability to live a long life, but to have comparatively good health and normal activities during almost all of one’s life. Research on lipoic acid, at OSU and elsewhere, suggests it has value toward that goal.
Continued research will explore this process and its role in circadian function, whether it can be sustained, and optimal intake levels that might be needed to improve health.Linus Pauling Institute Media Contact: David Stauth Source:

OSU chemists have developed a new technology to tell whether a common malaria medication is genuine, and it could save thousands of lives.
CORVALLIS, Ore. – Chemists and students in science and engineering at Oregon State University have created a new type of chemical test, or assay, that’s inexpensive, simple, and can tell whether or not one of the primary drugs being used to treat malaria is genuine – an enormous and deadly problem in the developing world.
The World Health Organization has estimated that about 200,000 lives a year may be lost due to the use of counterfeit anti-malarial drugs. When commercialized, the new OSU technology may be able to help address that problem by testing drugs for efficacy at a cost of a few cents.
When broadly implemented, this might save thousands of lives every year around the world, and similar technology could also be developed for other types of medications and diseases, experts say.
Findings on the new technology were just published in Talanta, a professional journal.
“There are laboratory methods to analyze medications such as this, but they often are not available or widely used in the developing world where malaria kills thousands of people every year,” said Vincent Remcho, a professor of chemistry and Patricia Valian Reser Faculty Scholar in the OSU College of Science, a position which helped support this work.
“What we need are inexpensive, accurate assays that can detect adulterated pharmaceuticals in the field, simple enough that anyone can use them,” Remcho said. “Our technology should provide that.”
The system created at OSU looks about as simple, and is almost as cheap, as a sheet of paper. But it’s actually a highly sophisticated “colorimetric” assay that consumers could use to tell whether or not they are getting the medication they paid for – artesunate - which is by far the most important drug used to treat serious cases of malaria. The assay also verifies that an adequate level of the drug is present.
In some places in the developing world, more than 80 percent of outlets are selling counterfeit pharmaceuticals, researchers have found. One survey found that 38-53 percent of outlets in Cambodia, Laos, Myanmar, Thailand and Vietnam had no active drug in the product that was being sold. Artesunate, which can cost $1 to $2 per adult treatment, is considered an expensive drug by the standards of the developing world, making counterfeit drugs profitable since the disease is so prevalent.
Besides allowing thousands of needless deaths, the spread of counterfeit drugs with sub-therapeutic levels of artesunate can promote the development of new strains of multi-drug resistant malaria, with global impacts. Government officials could also use the new system as a rapid screening tool to help combat the larger problem of drug counterfeiting.
The new technology is an application of microfluidics, in this instance paper microfluidics, in which a film is impressed onto paper that can then detect the presence and level of the artesunate drug. A single pill can be crushed, dissolved in water, and when a drop of the solution is placed on the paper, it turns yellow if the drug is present. The intensity of the color indicates the level of the drug, which can be compared to a simple color chart.
OSU undergraduate and graduate students in chemistry and computer science working on this project in the Remcho lab took the system a step further, and created an app for an iPhone that could be used to measure the color, and tell with an even higher degree of accuracy both the presence and level of the drug.
The technology is similar to what can be accomplished with computers and expensive laboratory equipment, but is much simpler and less expensive. As a result, use of this approach may significantly expand in medicine, scientists said.
“This is conceptually similar to what we do with integrated circuit chips in computers, but we’re pushing fluids around instead of electrons, to reveal chemical information that’s useful to us,” Remcho said. “Chemical communication is how Mother Nature does it, and the long term applications of this approach really are mind-blowing.”
Colorimetric assays have already been developed for measurement of many biomarker targets of interest, Remcho said, and could be expanded for a wide range of other medical conditions, pharmaceutical and diagnostic tests, pathogen detection, environmental analysis and other uses.
With a proof of concept of the new technology complete, the researchers may work with the OSU Advantage to commercialize the technology, ultimately with global application. As an incubator for startup and early stage organizations, OSU Advantage connects business with faculty expertise and student talent to bring technology such as this to market.College of Science Media Contact: David Stauth Source:

Girls and young women who post sexy or revealing photos are viewed by their female peers as less attractive and less competent, research shows.
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-Cascades Campus Media Contact: Michelle Klampe Source:

Research suggests that antibiotics are probably being used more than is appropriate in hospice patients, sometimes making life for the terminally ill worse instead of better.
CORVALLIS, Ore. – New research suggests that use of antibiotics is still prevalent among terminal patients who have chosen hospice care as an end-of-life option, despite little evidence that the medications improve symptoms or quality of life, and sometimes may cause unwanted side effects.
The use of antibiotics is so engrained in contemporary medicine that 21 percent of patients being discharged from hospitals directly to a hospice program leave with a prescription for antibiotics, even though more than one fourth of them don’t have a documented infection during their hospital admission.
About 27 percent of hospice patients are still taking antibiotics in the final week of their life.
This raises serious questions about whether such broad and continued antibiotic use is appropriate in so many hospice cases, experts say, where the underlying concept is to control pain and protect the remaining quality of life without aggressively continuing medical treatment.
Additional concerns with antibiotic use, the study concluded, include medication side effects and adverse events, increased risk of subsequent opportunistic infections, prolonging the dying process and increasing the risk of developing antibiotic resistant microorganisms.
The findings were just published in Antimicrobial Agents and Chemotherapy by researchers from Oregon State University and the Oregon Health & Science University. It was supported by the National Institutes of Health.
“Hospice care is very patient centered and in terminal patients it focuses on palliative care and symptom relief, not curative therapy,” said Jon Furuno, an associate professor in the Oregon State University/Oregon Health & Science University College of Pharmacy.
“It’s not for everyone, and it’s a serious decision people usually make in consultation with their family, nurses and doctors. These are tough conversations to have.
“Having decided to use hospice, however, the frequency and prevalence of antibiotic use in this patient population is a concern,” Furuno said. “Antibiotics themselves can have serious side effects that sometimes cause new problems, a factor that often isn’t adequately considered. And in terminally-ill people they may or may not work anyway.”
Issues such as this, Furuno said, continue to crop up in the evolving issue of hospice care, which is still growing in popularity as many people choose to naturally allow their life to end with limited medical treatment and often in their own homes. Hospice is covered by Medicare for people with a life expectancy of less than six months, helps to control medical costs and reduce hospital stays, and its services are now used by more than one third of dying Americans.
Unnecessary and inappropriate antibiotic use is already a concern across all segments of society, researchers said in the report, and more efforts are clearly needed to address the issue in hospice patients. The design of the study probably leads to it underestimating the significance of the problem, the researchers wrote in their conclusion.College of Pharmacy Media Contact: David Stauth Source:
