The use of broad equity-based compensation for employees in the lower ranks of an organization is a puzzle for standard economic theory: any positive incentive effects should be diminished by free rider problems, and undiversified employees should discount company equity heavily. We point out that employees do not appear to value company stock as prescribed(More)
We relate the performance of mutual fund trades to their motivation. A fund manager who believes that a stock is significantly mispriced will want to trade in its shares. However, heavy investor outflows (inflows) will constrain the manager by forcing him or her to control liquidity by selling (buying) stocks. Our results support the hypotheses that(More)
Prior small studies have shown multiple benefits of frequent nocturnal hemodialysis compared to conventional three times per week treatments. To study this further, we randomized 87 patients to three times per week conventional hemodialysis or to nocturnal hemodialysis six times per week, all with single-use high-flux dialyzers. The 45 patients in the(More)

The fund industry is larger in countries with stronger rules, laws, and regulations, and specifically where mutual fund investors’ rights are better protected. The industry is also larger in countries with wealthier and more educated(More)
Mechanistically, hyperbaric oxygen (HBO) appears useful for the treatment of osteomyelitis. HBO increases the oxygen tension in infected tissue, including bone. An adequate oxygen tension is necessary for oxygen-dependent killing of organisms by the polymorphonuclear leukocytes and for fibroblast activity leading to angiogenesis and wound healing. HBO has a(More)
Three patients with hyperthyroidism due to deliberate intake of excessive amounts of L-thyroxine are described wherein death was "instantaneous" and presumably due to ventricular fibrillation. Hyperthyroidism was not recognized on admission in two of these patients because of atypical presentations. Autopsy was performed in two patients. In one patient no(More)
BACKGROUND Chronic anal fissures (CAF) are caused by anal sphincter hypertonia leading to an ischaemic ulcer. By inducing temporary sphincter relaxation, botulinum toxin (Botox) injection has been shown to heal CAF in approximately 73-96% of cases in clinical trials. AIM This study looks at the efficacy of Botox clinical practice. METHODS The medical(More)
