like Treasury bonds, and (2) low-grade bonds are more sensitive to stock returns. The implications of these studies may be limited in many situations of interest, however. For example, hedge funds often take highly levered positions in corporate bonds while hedging away interest rate risk by shorting

;similar ' data rectangles together, to minimize the area and perimeter of the resulting minimum bounding rectangles (MBRs). Following [19] we have chosen the so-called '2D-c ' method, which sorts rectangles according to the Hilbert value of the center of the rectangles. Given the ordering, every

Finite element solvers are a basic component of simulation applications; they are common in computer graphics, engineering, and medical simulations. Although adaptive solvers can be of great value in reducing the often high computational cost of simulations they are not employed broadly. Indeed

.3-$1.5 million in external costs; a heavy drug user, $370,000 to $970,000; and a high-school dropout, $243,000 to $388,000. Eliminating duplication between crimes committed by individuals who are both heavy drug users and career crimi-nals results in an overall estimate of the "monetary value of saving a

, in 1998 it cost $5,021 to keep a child in a part-day Head Start program for 34 weeks a year. The two-year, part-day Perry Preschool intervention cost $12,884 per child (in 1999 dollars) The methodology used in this study follows Currie and Thomas II. Data The PSID began in 1968 with a survey of 4

Multihop wireless mesh networks can provide Internet access over a wide area with minimal infrastructure expenditure. In this work, we present a measurement driven deployment strategy and a data-driven model to study the impact of design and topology decisions on network-wide performance and cost

. The analysis of survey data collected from 147 genomics scientists found that curators of genomic data valued quality criteria that can be assessed through direct examination of the data more highly, while end-users placed a high value on the quality criteria that can be assessed indirectly

of the options listed above would work as displayed in Differences in magnitude and distribution of cost across the population and over time would surely be critical in contemplating the potentially limiting role of resource availability (Determinant #2) for options A through C. If the threats appeared when

and winter precipitation Seasonal cycles of carbon uptake and loss The seasonal dynamics of each of the forest sites in are illustrated in Daytime uptake The tropical forest site showed the least seasonality in both daytime uptake (mean value 5·2 g C m -2 d -1 ) and night-time release (mean value 3·5 g C m

by investors over time. For example, the growth/value category was not widely used in 1980. Instead, we impose no categorical structure on the data and just follow the flows. Most strikingly, we are able to document that the fund flow effect is highly related to the value effect, a finding that could not have
