Reduction of power consumption for any computer system is now an important issue, although this should be done in a manner that is not detrimental to the user base. We present a number of policies that can be applied to multi-use clusters where computers are shared between interactive users and high-throughput computing. We evaluate policies by trace-driven(More)
This paper proposes a method for measuring investor risk appetite based on the variation in the ratio of risk-neutral to subjective probabilities used by investors in evaluating possible future returns to an asset. Unlike other indicators advanced in the literature, our measure of market sentiment distinguishes risk appetite from risk aversion, and is(More)
OBJECTIVE To characterize white matter abnormalities in adolescents with early-onset schizophrenia (EOS) relative to 3 comparison groups (adolescents at clinical high risk for developing schizophrenia [CHR], adolescents with cannabis use disorder [CUD], and healthy controls [HC]), and to identify neurocognitive correlates of white matter abnormalities in(More)
OBJECTIVE In early-onset schizophrenia (EOS), the earliest structural brain volumetric abnormalities appear in the parietal cortices. Early exposure to cannabis may represent an environmental risk factor for developing schizophrenia. This study characterized cerebral cortical gray matter structure in adolescents in regions of interest (ROIs) that have been(More)
The use of open, Internet-based communications for business-to-business (B2B) interactions requires accountability for and acknowledgment of the actions of participants. Accountability and acknowledgment can be achieved by the systematic maintenance of an irrefutable audit trail to render the interaction non-repudiable. To safeguard the interests of each(More)
The paper reviews psychological and social scientific research on lay attitudes to food risks. Many experts (scientists, food producers and public health advisors) regard public unease about food risks as excessive. This expert-lay discrepancy is often attributed to a 'knowledge deficit' among lay people. However, much research in psychology and sociology(More)
There is a growing tension within large organisations such as universities between the desire to perform vast amounts of computational processing and the desire to reduce power consumption by switching off computers. This situation will only worsen as computational problems get larger and the desire to save energy escalates. Through careful management of(More)
The wide variety of services and resources available over the Internet presents new opportunities to create value added, inter-organisational Composite Services (CSs) from multiple existing services. The resulting CS can involve close interaction among the constituent services of participating organisations. To preserve their autonomy and privacy, each(More)
