App also allows users to communicate with MU animal science experts
COLUMBIA, Mo. – Each year, overheated cattle cost farmers more than $1.2 billion. Now, researchers at the University of Missouri have created a smartphone application that can detect when a cow is at risk for heat stress. The app also can offer the best methods for intervention.
“Cows are like the rest of us,” said Don Spiers, professor of animal sciences at MU’s College of Agriculture, Food and Natural Resources, who led the team that developed the app. “They slow down in hot and humid weather. When stressed by too much heat, they stop eating, and thus, fail to grain weight or produce milk.” (more…)
Outdoor recreationists should take precautions to avoid problems with bears in southern Missouri
COLUMBIA, Mo. — For nearly a century, the only bears known to reside in Missouri were on the state flag or in captivity. Unregulated hunting and habitat loss had wiped out most black bears in Missouri, Arkansas and Oklahoma by the 1920s. Now, thanks to a reintroduction program in Arkansas during the 50s and 60s, hundreds of bears amble through the forests of southern Missouri, according to a joint study by University of Missouri, Mississippi State University, and Missouri Department of Conservation biologists, who warn that although the bear population is still small, outdoor recreationists and homeowners should take precautions in the Ozark forest to avoid attracting bears.
“Black bears normally do not attack humans, but they will ransack picnic baskets, tear through garbage bags or even enter buildings looking for food,” said Lori Eggert, associate professor of biological sciences in MU’s College of Arts and Science. “Although some Missourians may be concerned, the return of black bears to Missouri is actually a good sign. It means parts of the state’s forests are returning to a healthy biological balance after nearly two centuries of intensive logging and exploitation.” (more…)
COLUMBIA, Mo. — CEOs need to demonstrate strong leadership and good decision-making skills, but CEOs with over-confidence can involve their companies in riskier ventures and put investors’ funds at risk, according to a new study from the University of Missouri, Georgia Tech University and the University of Texas-Arlington.
“Over-confident CEOs feel they have superior decision-making abilities and are more capable than their peers,” said Stephen Ferris, professor of finance in the MU Trulaske College of Business. “Unfortunately, they tend to make decisions about mergers or acquisitions that can be viewed as risky. For example, CEOs who are over-confident tend to target companies that do not focus on their core line of business. Generally speaking, mergers that diversify companies don’t work.” (more…)
COLUMBIA, Mo. — Nations that have freedom of information (FOI) laws in place tend to have lower incidents of corruption than those with no similar laws, a new University of Missouri study found. In comparing data from 168 countries, Edson Tandoc, Jr., a doctoral candidate in the MU School of Journalism also found that having an FOI law is linked to higher levels of human development. He says governments of many countries enact FOI laws in an effort to stop corruption, but while FOI laws work to reduce corruption over time, they are not a quick fix.
“Because it takes years for these laws to become fully effective, FOI laws should not be considered only as a corrective measure,” Tandoc said. “Countries without FOI laws should not wait for corruption to strike before they get serious about passing these laws because they will not cure the problems overnight.” (more…)
Research could guide business and political decisions as well as charity work
COLUMBIA, Mo. – A business may build a better reputation as a good corporate citizen by donating $100,000 to ten charities, as opposed to $1 million to one charity, suggested University of Missouri anthropologist Shane Macfarlan. Contrary to earlier assumptions in theoretical biology, Macfarlan’s research found that helping a greater number of people builds a positive reputation more than helping a few people many times. The results of this research can offer guidance to businesses and politicians on how to improve their public images.
“Good reputations are good business. For example, buyers tend to purchase from merchants with numerous positive ratings on internet-based commerce websites, such as Amazon and eBay,” said Shane Macfarlan, post-doctoral anthropology researcher in MU’s College of Arts and Science. “Beyond the realm of commerce, the power of a positive reputation may have influenced the evolution of language and cooperation in our species. In our study, we found that an individual’s reputation improves more after helping a greater number of people compared to performing a greater number of helpful acts for fewer people.” (more…)
Scientists find that essential fatty acid found in vegetable oils does not promote inflammation in humans
COLUMBIA, Mo. — A typical American consumes approximately 3 or more tablespoons of vegetable oil each day. Vegetable oils, like those from soy, corn and canola, are a significant source of calories and are rich in linoleic acid (LA), which is an essential nutrient. Since the 1970s, researchers have known that LA helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing. A new study from the University of Missouri contradicts that claim.
In the study, “Effect of Dietary Linoleic Acid on Markers of Inflammation in Healthy Persons: A Systematic Review of Randomized Controlled Trials,” researchers at the University of Missouri and the University of Illinois found that no link exists between vegetable oil consumption and circulating indicators of inflammation that are often associated with diseases such as heart disease, cancer, asthma and arthritis. While earlier animal studies have shown that a diet rich in LA can promote inflammation, MU animal sciences researcher Kevin Fritsche says that humans respond to LA differently. (more…)
COLUMBIA, Mo. – Currently, many recent college graduates still face the daunting task of searching for a job. While the job search process can be long and exhausting, a University of Missouri researcher has found that maintaining positivity and staying motivated can lead to a more successful job search.
“The search for a job can be stressful time in anyone’s life, especially first-time college graduates,” said Daniel Turban, professor of management at the MU Trulaske College of Business. “Job searching isn’t rewarding until the end of the search when a job is actually secure.” (more…)
Understanding microbe communities could improve wetland wastewater treatment systems
COLUMBIA, Mo. – Wetlands serve as the Earth’s kidneys. They filter and clean people’s water supplies while serving as important habitat for many species, including iconic species like cattails, cranes and alligators. Conventional ecosystem health assessments have focused on populations of these larger species. However, the tiny, unseen creatures in the wetlands provided crucial indicators of the ecosystems’ health in a study by University of Missouri Associate Professor of Engineering Zhiqiang Hu and his team. Using analysis of the microbiological health of wetlands is cheaper and faster than traditional assessments, and could lead to improvements in harnessing natural processes to filter humans’ wastewater.
“During road and building construction, engineers must sacrifice wetlands to development, but laws dictate that these lost wetlands be compensated for by establishing a wetland somewhere else,” said Hu. “Our research could be applied to both monitor the success of these compensation wetlands and guide conservationists in inoculating new engineered ecosystems with the correct types of microorganisms.” (more…)
