Clinical and experimental research has shown that reduced levels of brain-derived neurotrophic factor (BDNF) may be a risk factor for neurological complications associated with HIV-1 infection. We are actively testing genetically modified macrophages for their possible use as the cell-based gene delivery vehicle for the centr...

Literature on attention and its asset pricing implications suggests that people pay attention to stocks that appear in the media and people tend to buy attention-grabbing stocks. Stock recommendations from the TV show Mad Money and Wall $treet Week have proven to catch people’s attention and create price pressure on the stocks recomm...
Many empirical studies document the value effect. One explanation is that investors overreact to growth aspects for growth stocks. We apply Stein's (1989) method to investigate whether the degree of overreaction differs between value and growth stocks using the implied volatility from option prices. A finding of overreaction for either value stocks or growth stocks would lend support to overrea...

U...
The current system of managing fish stocks in the North Atlantic is failing: many key stocks are at historically low levels and fishing effort is being restricted while capacity remains high. The traditional scientific approach used by International Council for the Exploration of the Sea (ICES) to provide advice on fish stocks is based on complex analytical models of the fishery that require de...

Presently, assessment of carbon stocks in the context of greenhouse gas (GHG)-reporting on a nation-by-nation basis focuses on the terrestrial realm, i.e., carbon held in living plant biomass and soils, and on potential changes in these stocks in response to anthropogenic ac...
