Firms pressure sales people to invest in costly internal negotiations: INFORMS study
(Institute for Operations Research and the Management Sciences) In many firms sales people spend as much time negotiating internally for lower prices as they do interacting with customers. A new study appearing in the November issue of Marketing Science, a publication of the Institute for Operations Research and the Management Sciences, INFORMS, finds that firms should allow their sales people to 'waste' energy on internal negotiations. In fact, it says, firms should make the process wasteful on purpose.

Hee Oh to receive 2015 AMS Satter Prize
(American Mathematical Society) Hee Oh of Yale University will be awarded the 2015 AMS Ruth Lyttle Satter Prize at the Joint Mathematics Meetings in January in San Antonio, Texas. Oh is honored for '[her] fundamental contributions to the fields of dynamics on homogeneous spaces, discrete subgroups of Lie groups, and applications to number theory.'

When vaccines are imperfect
(Society for Industrial and Applied Mathematics) The control of certain childhood diseases is difficult, despite high vaccination coverage in many countries. One of the possible reasons for this is 'imperfect vaccines,' that is, vaccines that fail either due to 'leakiness,' lack of effectiveness on certain individuals in a population, or shorter duration of potency. In a paper publishing today in the SIAM Journal on Applied Mathematics, Felicia Magpantay et al. use a mathematical model to determine the consequences of vaccine failure and resulting disease dynamics.

A new tool for identifying onset of local influenza outbreaks
(University of Massachusetts at Amherst) Hospital epidemiologists and others responsible for public health decisions do not declare the start of flu season lightly. All the extra precautions cost time and money, so they do not want to declare flu season too early. For hospitals, there is a strong incentive to define a really clear period as flu season.

Epidemic spreading and neurodegenerative progression
(PLOS) Researchers from the Montreal Neurological Institute have used a model inspired by patterns of epidemic disease spreading to map how misfolded proteins propagate within the brain.

Radiation monitors tested on space station to fly on Orion
(University of Houston) Already tested on the International Space Station, six radiation detectors developed by a team from the University of Houston physics department and their NASA colleagues have paved the way for two new devices to fly on the first test flight of NASA's new Orion spacecraft.

Pavel Gurevich wins the 2014 von Kaven Award
(Deutsche Forschungsgemeinschaft) The German Research Foundation has selected mathematician PD Pavel Gurevich, Ph.D., from the Free University of Berlin to receive the 2014 von Kaven Award. Gurevich conducts research on nonlinear partial differential equations, focusing in particular on hysteresis phenomena and pattern-forming processes.

DFG establishes 14 new Research Training Groups
(Deutsche Forschungsgemeinschaft) The German Research Foundation is establishing 14 new Research Training Groups to further support early career researchers in Germany.

'Green Revolution' changes breathing of the biosphere
(University of Maryland) The intense farming practices of the 'Green Revolution' are powerful enough to alter Earth's atmosphere at an ever-increasing rate, boosting the seasonal amplitude in atmospheric carbon dioxide to about 15 percent over the past five decades. That's the key finding of a new atmospheric model, which estimates that on average, the amplitude of the seasonal oscillation of carbon dioxide in the atmosphere is increasing at a rate of 0.3 percent every year.

Victor Kac to receive 2015 AMS Steele Prize for Lifetime Achievement
(American Mathematical Society) Victor Kac of the Massachusetts Institute of Technology will be awarded the 2015 AMS Leroy P. Steele Prize for Lifetime Achievement at the Joint Mathematics Meetings in January in San Antonio, Texas. He is honored for 'his groundbreaking contributions to Lie Theory and its applications to Mathematics and Mathematical Physics.'
