U.S. Workers Are ‘Giving Away The Store,’ Costing Firms Billions

EAST LANSING, Mich. — Nearly 70 percent of the nation’s service employees give away free goods and services – from hamburgers to cable TV – costing companies billions of dollars a year, according to a groundbreaking study.

Clay Voorhees, study co-author and marketing expert at Michigan State University, said one of the best ways to combat this illegal practice – called “sweethearting” – is through better screening of job candidates. (more…)

‘Explorers’ Use Uncertainty And Specific Area of Brain

*As they try to find the best reward among options, some people explore based on how uncertain they are about the outcome of the options.  Those who employ that thought process, unlike people who use other strategies, uniquely harness the computational power of the rostrolateral prefrontal cortex, a new study finds.*

PROVIDENCE, R.I. [Brown University] — Life shrouds most choices in mystery. Some people inch toward a comfortable enough spot and stick close to that rewarding status quo. Out to dinner, they order the usual. Others consider their options systematically or randomly. But many choose to grapple with the uncertainty head on. “Explorers” order the special because they aren’t sure they’ll like it. It’s a strategy of maximizing rewards by discovering whether as yet unexplored options might yield better returns. In a new study, Brown University researchers show that such explorers use a specific part of their brain to calculate the relative uncertainty of their choices, while non-explorers do not. (more…)

3-D Laser Map Shows Earthquake Zone Before and After

*Geologists learn how earthquakes change the landscape — down to a few inches*

Geologists have a new tool to study how earthquakes change the landscape–down to a few inches. It’s giving scientists insights into how earthquake faults behave.

In this week’s issue of the journal Science, a team of scientists from the United States, Mexico and China reports the most comprehensive before-and-after picture yet of an earthquake zone, using data from the magnitude 7.2 event that struck near Mexicali, Mexico, in April 2010. (more…)

Distorted Art

*UD art professor creates sculptures from baking flour, aluminum*

There’s a quality to David Meyer’s art that’s both conceptual and ephemeral, sort of like watching the clouds roll by.

You see with your mind, not your eyes. And even then, as with clouds, shapes move. Things change.

There’s art in distortion. (more…)

Why Bad Immunity Genes Survive

*Study implicates “arms race” between genes and germs*

Biologists have found new evidence of why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs–even though some of those genes make vertebrate animals susceptible to infections and to autoimmune diseases.

“Major histocompatibility complex” (MHC) proteins are found on the surfaces of most cells in vertebrate animals. They distinguish proteins like themselves from foreign proteins, and trigger an immune response against these foreign invaders. (more…)
