Ball State University experts are available to provide information and background on a variety of issues. Story ideas include:

UNEMPLOYMENT TAKES TOLL PSYCHOLOGICALLY: People with low self-esteem are more likely to suffer bouts of depression as a result of losing their jobs as compared to individuals with high self-esteem, says Jay Zimmerman, a psychologist. Depressed workers in their 40s and 50s have an increased risk of suicide, while women, especially single mothers, also often feel trapped.

GLUCOSOMINE HELPS REBUILD CARTILAGE: As people age cartilage in their joints wears thin causing stiffness, a sign of the onset of osteoarthritis, says Dave Pearson, an exercise physiologist. The best way to turn back the clock is to add glucosomine, a nutritional supplement, to your diet. Glucosomine contains nutrients the body turns into cartilage lubricant. Research shows that it relieves pain and may help repair cartilage. The average person should notice a difference after about two months. Taking it now may help forestall arthritis in later years.

MANY PERSONAL TRAINERS LACK PROPER EDUCATION: Millions of Americans have hired personal trainers to help them develop and maintain a level of overall fitness, but many of these "professionals" have no little or no formal education, says Mitch Whaley, an exercise physiologist. He recommends people wanting a personal trainer seek out individuals certified by the American College of Sports Medicine or the National Strength and Conditioning Association. Both groups have the highest standards in the field.

AMERICAN ECONOMY MAY BE DOWN, BUT NOT OUT: Several recent reports show the U.S. economy entered 2003 with its momentum nearly spent. On the eve of an impending war that has already rattled financial markets, that's not a scenario the American public would have wished for, says Patrick Barkey, director of economic and policy studies. However, the economy took some tentative, but important, steps ahead at the close of last year. With a successful resolution of the current conflict, the prospects for healthy growth ahead may still be bright.

STUDY FINDS OLDER ADULTS DISLIKE NEGATIVE ADS: A survey of older Americans finds that 61.5 percent would not buy a product featured in an advertisement that ridicules senior citizens. The study also found that older adults find such advertisements are harmful because they reinforce negative stereotypes, says Robert Gustafson, a journalism professor.
