This paper examines the impact of foreign investors on stock returns in Korea from November 30, 1996 to the end of 1997 using order and trade data. We "nd strong evidence of positive feedback trading and herding by foreign investors before the period of Korea's economic crisis. During the crisis period, herding falls, and positive feedback trading by(More)
We can only estimate the distribution of stock returns, but from option prices we observe the distribution of state prices. State prices are the product of risk aversion – the pricing kernel – and the natural probability distribution. The Recovery Theorem enables us to separate these to determine the market's forecast of returns and risk aversion from state(More)
BACKGROUND To demonstrate the efficacy of intravitreal methotrexate for treating intraocular lymphoma. CASE A 55-year-old immunocompetent Asian man was diagnosed with intraocular lymphoma. OBSERVATIONS The patient was initially managed by intravenous administration of high-dose methotrexate. Because vitreous cells persisted after systemic chemotherapy,(More)
PURPOSE To compare anterior chamber depth (ACD) measurements using two non-contact optical devices, Pentacam and IOLMaster, and a contact device, ultrasonic A-scan in phakic and pseudophakic eyes. METHODS Ninety phakic and 94 pseudophakic eyes were enrolled in this prospective study. The difference between ACD measurements by the three devices was(More)
Pancreatic cancer is a lethal disease where specific early detection biomarkers would be very valuable to improve outcomes in patients. Many previous studies have compared biosamples from pancreatic cancer patients with healthy controls to find potential biomarkers. However, a range of related disease conditions can influence the performance of these(More)
Assignment of glycosylation sites and site microheterogeneity is of both biological and clinical significance. Herein, the detailed N-glycosylation pattern of human serum alpha-2-macroglobulin was studied using an integrative approach, including permethylation of N-glycans, collision induced dissociation (CID) and electron transfer dissociation (ETD) of(More)
While peptide-level labeling using isobaric tag reagents has been widely applied for quantitative proteomics experiments, there are comparatively few reports of protein-level labeling. Intact protein labeling could be broadly applied to quantification experiments utilizing protein-level separations or enrichment schemes. Here, protein-level isobaric(More)
For a long list of investment " biases, " e.g., home bias, loss aversion, and performance chasing, we find that genetic differences explain up to 45% of the variation across individual investors. The genetic factors that influence investment biases are also found to affect behaviors in other, non-investment, domains. This evidence is consistent with a view(More)
PURPOSE To determine the effect of cycloplegia on corneal thickness, corneal curvature, anterior chamber depth (ACD), angle-to-angle (ATA) and white-to-white (WTW) distances, and axial length (AL). METHODS Changes in corneal thickness, corneal curvature, ACD, ATA and WTW distances, and AL with and without cycloplegia were analyzed in 31 eyes of 31 young(More)
An Enterobacter cloacae blood culture isolate expressing carbapenem resistance via the Klebsiella pneumoniae carbapenemase KPC-2 gene is reported. To our knowledge, this is the first report of a nosocomial isolate with carbapenemase-mediated resistance causing infection in a patient from Tennessee.
