Brock psychology professor seeks participants for two sleep studies

May 22, 2015

We’ve all done it: pressed the “send” button too quickly on that nasty e-mail, tweeted something we thought was hilarious but actually offensive, or snapped at our kids for some innocent remark they’ve made.

Chances are we did this on a day when we’ve had less than optimal sleep the night before.

Another scenario: on those rare occasions when we’ve curled up in the middle of the day to take a quick siesta, we seem to be sharper, more focused and can recall things easier once we awaken from our slumber.

Brock University psychology professor and sleep expert Kimberly Cote is conducting two research projects that will shed more light on how the brain functions when we have less - and more - sleep than usual.

Brock researchers find rosemary extract effective in diabetes treatment

May 21, 2015

Brock researchers have discovered the herb rosemary does more than pair well with mushrooms or roast chicken. They found that extract from the evergreen-like herb increases the transport of glucose into muscle cells, working much like drugs used to treat Type 2 diabetes.

Health Sciences Prof. Evangelia Tsiani worked on the project with her graduate student and the study’s primary author Madina Naimi as well as Chemistry researchers T.C. Stamatatos and D.I. Alexandropoulos, and McMaster University researcher Theodoros Tsakiridis.

Their findings have been published in a paper titled “Increased skeletal muscle glucose uptake by rosemary extract through AMPK activation.” The results complement Tsiani’s previous work studying the positive effects of resveratrol, an antioxidant common in red wine, and naringenin, a citrus flavonoid.

Free carbon credits can increase profits for polluters: Brock-Guelph study

May 20, 2015

Government schemes that regulate greenhouse gas emissions through the trading of carbon credits can actually increase profits for high-polluting companies if carbon credits are initially given to these companies free of charge, says new Brock University research.

Economist Marcel Oestreich and University of Guelph economist Ilias Tsiakas analyzed the impact on German industries of the European Union’s Emissions Trading System, launched in 2005 to combat climate change.

Under the system, regulators place a specific limit – or “cap” – on the amount of greenhouse gasses that factories, power plants and other companies are allowed to emit into the environment.

Some companies emit less than their limit, while others emit more. The ones that emit less can sell the difference to companies that emit more than their limit through certificates commonly known as “carbon credits.”

Trio of awards for dramatic arts professor

May 19, 2015

It has been a busy spring for Joe Norris.

In the midst of packing up his office to transfer to the new Marilyn I. Walker School of Fine and Performing Arts, the dramatic arts professor added three newly acquired items to take with him: two awards from the American Educational Research Association and one from Brock University.

Norris and Richard D. Sawyer from Washington State University captured the association’s Significant Contribution to Educational Measurement and Research Methodology Award.

They were recognized for their book, Understanding Qualitative Research: Duoethnography, which Norris and Sawyer co-wrote. The book details the duo’s new research methodology called “duoethnography.”

Scientists find that athletes don’t really need all of those drinks

May 11, 2015

New research by scientists at Brock University has debunked the widely-held belief that dehydration saps the strength of athletes performing in hot conditions.

It is common to see distance runners or cyclists gulp water and other drinks during long races, trying to replenish fluids and avoid the loss of strength that has long been accepted as a consequence of dehydration.

But the Brock study, published this month in the Scandinavian Journal of Medicine and Science in Sports, concludes there is no such impairment.

Lead researcher Stephen Cheung, a renowned kinesiologist whose research subjects have ranged from Olympic athletes to offshore oil workers, said his team’s findings refute the long-unquestioned tenet that water loss hinders a competitor’s performance.

This particular research involved 11 trained racing cyclists who wore IV drips while riding stationary bikes under competition-like conditions. Some cyclists had IV drips containing a saline solution to replenish fluids lost through sweat, but others had IV drips that were shams, providing no rehydration at all.

Brock-led arts documentary captures top prizes in international film competition

May 6, 2015

When young people are given the chance to tell their own stories in their own ways, amazing things can happen.

They produce plays that are both entertaining and informative. They deepen understanding of racism, bullying and other issues with which society grapples.

And they win international awards that affirm their creative ideas and work.

Such is the case with Commotion, a documentary arising out of a project of the same name that Department of Dramatic Arts associate professor Gyllian Raby and Carousel Players artistic director Pablo Felices Luna created three years ago in partnership with community groups.

Commotion captured two Prestige Film Awards for 2015: the Gold Award in the Educational/Instructional category, and the Silver Award for Research.
