ANN ARBOR, Mich. — The ongoing spread of non-native mussels in the Great Lakes has caused “massive, ecosystem-wide changes” throughout lakes Michigan and Huron, two of the planet’s largest freshwater lakes, according to a new University of Michigan-led study.

The blitzkrieg advance of two closely related species of mussels—the zebra and quagga—is stripping the lakes of their life-supporting algae, resulting in a remarkable ecological transformation and threatening the multibillion-dollar U.S. commercial and recreational Great Lakes fisheries. (more…)

Readability of Annual Reports Affects Accuracy of Analyst Forecasts

ANN ARBOR, Mich.—Stock analysts’ earnings forecasts for companies with hard-to-read annual financial reports are more informative, but less accurate, say University of Michigan researchers.

A new journal article in the May issue of Accounting Review shows that sell-side financial analysts expend greater effort to generate earnings forecasts of publicly traded firms with less readable 10-K filings. This increased effort by analysts results in earnings reports to investors that contain more information—but less accuracy and greater uncertainty. (more…)

Reframing Climate Change: It’s as Much Cultural as Scientific

ANN ARBOR, Mich.— While debate on climate change often strikes a caustic tone, the real impediment to meaningful dialogue is that the two sides often talk past each other in what amounts to a “logic schism,” says a University of Michigan researcher.

“In a logic schism, a contest emerges in which opposing sides are debating different issues, seeking only information that supports their position and disconfirms their opponents’ arguments,” said Andy Hoffman, the Holcim (U.S.) Professor of Sustainable Enterprise at U-M’s Ross School of Business and School of Natural Resources and Environment. “Each side views the other with suspicion, even demonizing the other, leading to a strong resistance to any form of engagement, much less negotiation and concession.” (more…)

Mating Mites Trapped in Amber Reveal Sex Role Reversal

ANN ARBOR, Mich.— In the mating game, some female mites are mightier than their mates, new research at the University of Michigan and the Russian Academy of Sciences suggests. The evidence comes, in part, from 40 million-year-old mating mites preserved in Baltic amber.

In a paper published March 1 in the Biological Journal of the Linnean Society, researchers Pavel Klimov and Ekaterina Sidorchuk describe an extinct mite species in which the traditional sex roles were reversed. (more…)

*New University of Michigan research shows higher education, religion, income levels influence Arab American support of organ donation*

ANN ARBOR, Mich. – U.S. organ procurement organizations looking to increase donation rates among Arab Americans can turn to new University of Michigan Health System research for recruitment ideas.

U-M researchers identified various factors – from education and income levels to gender and religion – that may predict how members of this population view organ donation, says lead study author Aasim I. Padela, M.D., an emergency physician and a Robert Wood Johnson Foundation Clinical Scholar at the U-M Health System. (more…)

Have We Changed Our Ways After the BP Oil Spill? Not Really

ANN ARBOR, Mich.—On the heels of last week’s federal recommendations to help prevent another BP oil spill disaster, a University of Michigan researcher says the tragedy has come close to acting as a catalyst for deeper change—but not quite.

“The BP oil spill is, potentially, a ‘cultural anomaly’ for institutional changes in environmental management and fossil fuel production,” said Andrew Hoffman, professor of management and organizations at the Ross School of Business and a professor at the School of Natural Resources and Environment. “But true change in our approach to handling issues related to oil drilling, oil consumption and environmental management have yet to occur.” (more…)

ANN ARBOR, Mich.— Organizational efforts to create and maintain an inclusive multicultural environment often face resistance by whites, says a University of Michigan researcher.

“Without the support of whites, organizations and educational settings will fail in their attempts to navigate and manage the complexities of diverse work forces and constituencies,” said Jeffrey Sanchez-Burks, an associate professor of management and organizations at Michigan’s Ross School of Business. “In the face of the dramatic projected growth in demographic diversity, such failure could have severe economic, social and political consequences.

Sick at Work and Surfing the Net? You’re Not Alone – or Are You?

ANN ARBOR, Mich.— Some scholars estimate that presenteeism, a relatively recent buzzword that applies to people who are less productive at work because of health issues, costs employers as much as three times the dollar amount as absenteeism in terms of lost productivity.

But researchers at University of Michigan believe those numbers may be inaccurate. A new opinion paper suggests that the tools for measuring and quantifying hours of lost productivity and translating those hours to dollars are unreliable and don’t capture the entire presenteeism picture, said Susan Hagen, an analyst from the U-M School of Kinesiology Health Management Research Center (HMRC).
