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.

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).

ANN ARBOR, Mich.— A table-top gamma-ray detector created at the University of Michigan can not only identify the presence of dangerous nuclear materials, but can pinpoint and show their exact location and type, unlike conventional detectors.
“Other gamma ray detectors can tell you perhaps that nuclear materials are near a building, but with our detector, you can know the materials are in room A, or room B, for example,” said Zhong He, an associate professor in the Department of Nuclear Engineering and Radiological Sciences.
“This is the first instrument for this purpose that can give you a real-time image of the radiation source. Not only can we tell you what material is there, but we can tell you where it is, and you can find it and walk towards it.”(more…)
ANN ARBOR, Mich. — When parents set up long-term savings accounts for college, business start-ups or home ownership, kids feel more financially and emotionally secure, new research shows.
The studies show the importance of families using child development accounts (CDA) as one measure to shift from an overreliance on credit and create a foundation for asset building. In other words, this program encourages households to maintain less debt and more savings. (more…)
ANN ARBOR, Mich. — Is your character shaped by where you live—or vice versa?
University of Michigan psychology researchers found that some cities lead with their heart—emotional and interpersonal strengths—while others lead with their head—intellectual and self-oriented strengths.
They also found such distinctions are also related to economic and political consequences. (more…)
NN ARBOR, Mich.—A groundbreaking new equation developed in part by researchers at the University of Michigan could do for organic semiconductors what the Shockley ideal diode equation did for inorganic semiconductors: help to enable their wider adoption. (more…)

ANN ARBOR, Mich
.— Twisting spires, concentric rings, and gracefully bending petals are a few of the new three-dimensional shapes that University of Michigan engineers can make from carbon nanotubes using a new manufacturing process.
The process is called “capillary forming,” and it takes advantage of capillary action, the phenomenon at work when liquids seem to defy gravity and spontaneously travel up a drinking straw.
The new miniature shapes have the potential to harness the exceptional mechanical, thermal, electrical, and chemical properties of carbon nanotubes in a scalable fashion, said A. John Hart, an assistant professor in the Department of Mechanical Engineering and in the School of Art & Design.
The 3D nanotube structures could enable countless new materials and microdevices, including probes that can interface with individual cells, novel microfluidic devices, and lightweight materials for aircraft and spacecraft. (more…)
ANN ARBOR, Mich.—Tuberculosis fights off the toxic agents, acidity and oxidants, that our immune system sends to destroy it, which is why the maddeningly drug-resistant bacterium can survive in harsh conditions in our bodies for essentially as long as its human host lives, new research shows.
