New Notre Dame paper examines household production and asset prices

2015-03-20
(Press-News.org) A new paper by Zhi Da, Viola D. Hank Associate Professor of Finance at the University of Notre Dame, find that residential electricity usage can track household production in real time and helps to price assets. "The importance of household production in economics has been recognized by Nobel Laureate Gary Becker back in 1960s but measuring what household produces at home has been an empirical challenge," Da said." For example, it has been a puzzle why certain industries such as consumer product, food, and clothing earn higher average returns than others such as steel and fabricated products. Our research shows that consumer product related industries are risky since they have high exposure to household production risk." In addition to its contribution to economic theory, the research can potentially prove useful for investors. "Investors can better compute the expected return on a stock or the cost of capital for a firm by taking into consideration the household production risk," Da said. "We find that average investors dislike times when the household production is low. Therefore, stocks or projects with low payoff in those times are more risky and would require higher expected return." The new paper is Zhi Da's latest effort to use electricity usage to examine finance and economics. "I found in another paper that the growth rate in industrial electricity usage negatively predicts next-one year stock market return," he said. "For example, if the industrial electricity usage this month is 1 percent lower than that in the same month last year, we predict the stock market return to be 0.92 percent higher in the next year." The new study appears in the Journal Management Science.

Letting go of the (genetic) apron strings

2015-03-20
A new study from Princeton University sheds light on the handing over of genetic control from mother to offspring early in development. Learning how organisms manage this transition could help researchers understand larger questions about how embryos regulate cell division and differentiation into new types of cells. The study, published in the March 12 issue of the journal Cell, provides new insight into the mechanism for this genetic hand-off, which happens within hours of fertilization, when the newly fertilized egg is called a zygote. "At the beginning, everything ...

Levee detonations reduced 2011 flood risk on Mississippi River, UCI-led study finds

2015-03-20
Irvine, Calif., March 20, 2015 - A controversial decision in 2011 to blow up Mississippi River levees reduced the risk of flooding in a city upstream, lowering the height of the rain-swollen river just before it reached its peak, according to a newly published computer modeling analysis led by UC Irvine scientists. The work focused on a Missouri agricultural area called the New Madrid Floodway that was inundated when the levees were detonated. The researchers found that the region would have flooded anyway if the river had been allowed to overtop the levee banks. And ...

From soda bans to bike lanes: Which 'natural experiments' really reduce obesity?

2015-03-20
Banning sodas from school vending machines, building walking paths and playgrounds, adding supermarkets to food deserts and requiring nutritional labels on restaurant menus: Such changes to the environments where people live and work are among the growing number of solutions that have been proposed and attempted in efforts to stem the rising obesity epidemic with viable, population-based solutions. But which of these changes actually make an impact? To answer that question, many public health researchers take advantage of "natural experiments"--looking at people's calorie ...

Research team discovers backup system that helps sustain liver during crisis

2015-03-20
BOZEMAN, Mont. - Scientists from Montana State University and Sweden have discovered an antioxidant system that helps sustain the liver when other systems are missing or compromised. Like a generator kicking in when the power fails or an understudy taking the stage when a lead actor is sick, the newly found system steps up during a crisis. It's fueled by methionine, an amino acid that can't be manufactured in the body and doesn't come from herbal teas or supplements. People get it only by eating protein. "This is an important finding," said Ed Schmidt, a professor in ...

National team led by Tufts CTSI finds navigators are integral to clinical research process

2015-03-20
BOSTON (March 20, 2015) - A study reported in this week's Science Translational Medicine found that qualified investigators are more likely to respond to opportunities for clinical trials if they are contacted by an institution-specific point person, or navigator. Jonathan M. Davis, MD, Tufts Clinical and Translational Science Institute (CTSI) Director of Regulatory Affairs and Chief of Newborn Medicine at Floating Hospital for Children at Tufts Medical Center and a multi-institution team of child health researchers instituted the Point-Person Project, a pilot study that ...

Pigs gain the same with corn-ethanol co-product as with corn-soybean meal diet, says study

2015-03-20
URBANA, Ill. - Distillers dried grains with solubles, or DDGS, are increasingly common in swine diets in the United States. In recent years, different types of DDGS have come on the market. "Ethanol plants use different procedures to produce DDGS, which results in different end products," said Hans H. Stein, a professor of animal sciences at University of Illinois. "To produce conventional DDGS, the corn is cooked to gelatinize starch prior to fermentation. However, uncooked DDGS can also be used if specific enzymes are used to pre-digest the starch prior to fermentation. ...

More than 25 percent of acne patients fail to get prescribed medications

2015-03-20
WINSTON-SALEM, N.C. - March 20, 2015 - Medicine obviously can't do much good if it sits on a pharmacy shelf. Yet more than one-quarter of the acne patients surveyed by Wake Forest Baptist Medical Center researchers didn't get medications prescribed by their dermatologists. Among the 143 acne patients who participated in the study, 27 percent failed to obtain all of their medications, including both prescription drugs and over-the-counter products. Those who were prescribed two medications had the highest rate of primary non-adherence - not getting a medication or not using ...

Researchers ID potential prognostic marker for recurrence of head & neck squamous cell carcinoma

2015-03-20
Philadelphia, PA, March 20, 2015 - A new study provides the first evidence that the mediator complex subunit 15 (MED15) may play a crucial role in the pathophysiology of head and neck squamous cell carcinoma (HNSCC). MED15 overexpression was found to be associated with higher mortality rates in HNSCC patients with cancer recurrence, particularly in oral cavity/oropharyngeal tumors, according to the study published in The American Journal of Pathology. MED15 overexpression was also associated with heavy alcohol consumption, which is an HNSCC risk factor. HNSCC is the sixth ...

New approach uses 'twisted light' to increase efficiency of quantum cryptography systems

2015-03-20
Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using "twisted light." This remarkable achievement is possible because the researchers used the orbital angular momentum of the photons to encode information, rather than the more commonly used polarization of light. The new approach doubles the 1 bit per photon that is possible with current systems that rely on light polarization and could help increase the efficiency of quantum cryptography systems. Quantum cryptography promises more secure communications. ...

Nova Southeastern University researcher part of team researching DNA of tigers
2015-03-20
FORT LAUDERDALE-DAVIE, Fla. - Tigers - they are some of nature's most beautiful, deadly and endangered species. In fact, living tigers are severely endangered in fragmented geographic areas across Asia - some reports show their numbers as low as 3,000 wild individuals. While there are efforts to help protect these magnificent creatures, more was needed in terms of research into the genetics of tigers. Nova Southeastern University researcher Stephen O'Brien was part of a team of research scientists from China, the United Kingdom, Israel, Russia and Qatar that looked at ...
