The prudent investment process.
Are you a CFO, CEO or treasure of your organization? Are you a member of the board of directors or investment or pension committees? If you answered "yes" to these questions, you are likely to be considered a fiduciary of investment assets. This position carries with it prestige, responsibility, and potential personal liability should something go wrong. Of course, liability will most likely occur only if a failure has occurred in carrying out fiduciary responsibilities. But what are those responsibilities? And what is the most appropriate way to manage investment decisions?
Do you have an IPS (investment policy statement)?
Academic studies have shown that over long-term time periods market timing is responsible for less than two percent of the variance of investment returns; security selection is responsible for less than five percent; while asset allocation policy (the desired mix of stocks and bonds) is responsible for almost 92 percent of the total return variation (see chart). This is yet another reason why it is critical to document the desired asset allocation policy and other guidelines for the portfolio in a written IPS.

The use of reaction time measures to evaluate nonword reading in primary progressive aphasia.
We reported on a subject with nonfluent primary progressive aphasia (PPA), NL, who demonstrated an impaired ability to make rhyme judgments (Dowhaniuk, Dixon, Roy, Black, & Square, in press). Our hypothesis was that these deficits represent a precursor to phonological alexia. However, no definitive evidence supported the existence of a phonological reading impairment as NL made relatively few errors reading nonwords. To further evaluate NL's nonword reading, nonword and real word reaction times were compared. NL's reaction times were significantly longer for only nonwords compared to the slowest control subject. We then assessed the first two stages of processing involved in nonword reading (Coltheart, 1996). NL did not demonstrate deficits with graphemic parsing or phoneme assignment. His continuing problems with auditory rhyme judgments support the presence of a phonological processing deficit not specific to reading. We conclude that reaction time measures allow for the detection of subtle nonword reading deficits.

The genucentric joint orthosis.
Pain and instability of the knee, major causes of disability in the geriatric population, impair independence in ambulation and transfers, and lead to falls that can result in fractures of the hip and further deterioration of the knee joint. The newly developed genucentric joint seems effective in meeting the needs of the multiple-handicapped elderly with mediolateral instability of the knee, poor blood circulation, and limited energy. Clinical results indicate that the genucentric joint orthosis can be worn with significant improvements in comfort when compared to more common knee orthoses, eliminating migration and reducing pistoning to the point where it is undetectable.
